DETAILED DESCRIPTION

This disclosure relates to an artificial Christmas tree and to a method of setting up an artificial Christmas tree.

As an example, the artificial Christmas tree includes a plurality of frame sections adapted to be assembled to form a tree frame. The tree frame has an outer frame portion adapted to support artificial tree features (e.g., branches). The artificial Christmas tree also includes a hoist adapted to move one or more of the frame sections in a longitudinal direction of the tree frame above an assembly location. As used herein, the term hoist can refer to a device and/or an action for raising up an object. For example, hoisting can including lifting the object from an elevated position above the object or lifting the object from a lower position that is below part of the object. Advantageously, the artificial tree features (e.g., branches, ornaments, lights and other decorations) may be applied to (or removed from) respective frame sections while each frame section is within physical reach of a user. As a result, the user does not need the use of ladders, cherry pickers or other lift equipment to set up and decorate the tree.

In some examples, the artificial Christmas tree includes a base and an elongated support. The elongated support is adapted to move relative to the base between a prone position and an erect position. For example, the artificial Christmas tree includes a hoist coupled to the base and/or support to move the support between respective prone and erect positions. While in the erect position, in which the distal end portion of the support is above the base, frame sections may be positioned and moved along the support toward the distal end portion of the support. As described herein, branches and/or other decorations may be coupled to the frame sections and the branches decorated before being moved upwardly along the support. A next frame section can be coupled to a preceding frame section. Branches are then coupled to the next frame section, which can be decorated without the use of ladders or other lift equipment. The process can be repeated until the assembly of the artificial Christmas tree is complete. A similar process may be implemented to disassemble the artificial Christmas tree by adjusting the height of the frame sections and removing branches and decorations (if desired), again without the use of ladders or other lift equipment.

As used herein, the term artificial simply means that the tree is not a live tree; however, parts of the tree may be synthetic materials, natural materials or a combination of natural and synthetic materials. For example, an artificial Christmas tree can refer to an artificial version of a conifer tree, such as an evergreen type of tree (e.g. a spruce, pine or fir tree). While the branches of a Christmas tree are usually green in color, such trees may be any color and may be lighted or unlit. As used herein, prone refers to a generally horizontal position, such as lying on the ground or another surface (e.g., a more horizontal than vertical orientation). Also, as used herein, erect refers to an upright or generally vertical position with respect to the ground or another surface (e.g., a more vertical than horizontal orientation).

FIGS.1and2depict an example of a base10that is part of an artificial Christmas tree200. The base10includes a central portion11that may be placed on a surface (e.g., ground) at a desired display location. For example, to facilitate moving the base10to the desired display location, the base10can include one or more wheels (e.g., a pair of wheels, three wheels, four wheels or more)8coupled to at or near a respective edge of the central portion11. The wheels8may be coaxial or otherwise arranged to facilitate controlled movement of the base10across the surface. A bracket (or other support structure) can be arranged and configured to support the respective wheels8with respect to the central portion11so the wheels8do not engage the surface until the base10is tilted (or pivoted) onto the wheels8. In this way, the base10remains stable (e.g., difficult to move) due to contact between the central portion11and the surface until the base10is tilted onto the wheels8enable rolling movement of the base across the surface. In another example, retractable caster wheels8can be coupled to the central portion11and remain retracted until activated (e.g., by stepping on or otherwise moving a respective foot pedal). When activated, the retractable wheels8can elevate the base10above surface to facilitate movement of the base across the surface. Using retractable wheels enables the base to be moved easily before assembly, during assembly or after assembly. In other examples, the base10may be carried, slid or otherwise transported to the desired display condition without wheels.

As shown in the example ofFIG.5, the base10includes a plurality of legs12extending outwardly from a central support structure14of the base. The legs12may be coupled to the base10by one or more fasteners15(e.g., nut and bolt, threaded locks, screws, clamps, and the like). While three legs12are shown in this example, different numbers of legs and/or different lengths may be used in other examples. The legs12are configured to provide additional stability after the base is positioned at the desired display location.

In some examples, the legs12may include telescoping leg portions13to provide adjustable lengths that may be set by a user. For example, the telescoping leg portions13may extend outwardly from the main part of the legs12and terminate in a respective distal end. As shown in the examples ofFIGS.5and6, the telescoping leg portions13are each moveable axially with respect to the respective legs12in the direction of arrow, shown as A1.FIGS.1and2show the legs12,13detached from the central part of the base10. That is, each of the main part of the legs12can be removable from and attachable to the base10, and further can be omitted in some examples. For example, each leg12may include a respective fastener17adapted to fix the length of the telescoping leg portion13with respect to its main leg12. For example, the fastener17can be implemented as a threaded T-bar lock, a bolt, a pin or another type of fastener configured to couple the legs12with respect to the base10. As disclosed herein, the telescoping leg portions13are adapted to provide additional support and stability by increasing the diameter of the base10, such as during assembly and/or disassembly of the tree200.

As a further example, after assembly of the artificial Christmas tree200has been completed, the telescoping leg portions13can be inserted (e.g., fully or nearly fully) into respective main legs12as to reduce the diameter of the base to be commensurate with (or less than) the outer diameter of the branches at or near the bottom of the tree, such as the completed artificial Christmas tree200shown inFIG.17. Alternatively, after assembly of the artificial Christmas tree200, the telescoping leg portions13may be removed from the main legs12and stored until needed again. For instance, at a time for disassembly of the artificial Christmas tree200, the telescoping leg portions13may be used again (e.g., re-inserted or pulled out from the main legs12) to provide increased stability during the disassembly process.

As shown in the example ofFIGS.3-9, the artificial tree200can include one or more elongated supports20. The elongated support20has a proximal end portion22and an opposite distal end portion24. The elongated support20can have a circular cross-sectional shape or another cross-sectional shape (e.g., rectangular, hexagonal or the like). The elongated support20can be formed of a rigid material, such as a metal, plastic, glass fiber, carbon fiber or the like.FIG.3depicts an example of the elongated support20, in which the support includes multiple (e.g., two or more) elongated sections23. The sections23are configured to be coupled together axially to provide the support having a desired length. For example, the support sections23can be coupled together by threaded fittings, friction fittings, welds, clamps, as well as other fittings or fasteners arranged and configured to couple the respective support sections together to form the elongated support20. The use of multiple sections23enables a user to configure the same tree system to a number of different tree heights by selecting a subset of the support sections23with a corresponding set of frame sections designed to form an artificial Christmas tree having a desired height. For example, for each of a plurality of different possible support lengths, a given set of frame sections having respective shapes and lengths may be used to assemble a tree having the height commensurate with the selected support length. The same base10further may be used for any selected tree height. In other examples, a single monolithic pole may be used as the elongated support20, and there can be a number of such poles for different height trees.

In some examples, one or more elongated flexible members (e.g., guy wires) may be coupled between a distal end portion24of the support20and ends of respective legs12or13to provide additional stability (e.g., during assembly and disassembly of the artificial Christmas tree). For example, as shown inFIG.9, one or more elongated flexible members25can be implemented as guy wires extending between a distal end portion24of the support20to respective hooks (e.g., C-shaped or closed hooks)19located at end portions of telescoping leg portions13. The elongated flexible members25can be implemented as wires, rope, cord, straps or elongated flexible members arranged and configured (e.g., as guy wires) to provide tension between the distal end portion24of the support20and the respective legs12,13. In other examples, guy wires could be coupled between the distal end portion24and the ground or other anchoring structure on or coupled to the ground.

In a further example, with reference back toFIG.1, the artificial Christmas tree200includes a mounting post16coupled to the base10. The mounting post16is moveable (in the direction of arrow A2) between a prone position (e.g., substantially parallel to the ground or more horizontal than vertical, as shown inFIG.1) and an erect position (e.g., substantially orthogonal to the ground or more vertical than horizontal, as shown inFIG.9). For example, the base10includes a coupling18configured to couple the mounting post16to the base10to enable the movement of the mounting post in the direction A2 between respective prone and erect positions. For example, the coupling18could be implemented as a joint, such as hinge, pivot joint, articulating joint, a track or other coupling arranged and configured to enable movement of the mounting post and elongated support20between prone and erect positions.

With reference toFIGS.4and5, the mounting post16is adapted to couple to the proximal end portion22of the support20, with the support and mounting post aligned in a substantially coaxial or parallel arrangement. In one example, the mounting post16includes a receptacle configured to receive the proximal end portion22of the support20within the receptacle. In another example, the proximal end of the support includes a receptacle that is configured to receive the mounting post16therein. Additionally or alternatively, the mounting post16may be coupled to proximal end portion22of the support using other means, such as mating threaded fittings, clips, clamps, hooks or other fasteners arranged and configured to couple the proximal end portion22and mounting post16together. In still other examples, the mounting post16may be omitted from the artificial Christmas tree200, and the elongated support can be moved to its erect position manually (e.g., by hand).

In an example, the central support structure14of the base10includes a retainer26adapted to retain the support20in the erect position. For example, the base10includes a support bracket30extending between respective spaced apart proximal and distal ends32and34. The proximal end32may be part of the central support structure. The retainer26may be located at or near the distal end34of the support bracket30. The retainer26may be implemented as a fastener, frame, bracket, enclosure, cage or guide arranged and configured to retain the support20in the erect position relative to the base10. For example, the support bracket30is implemented as a rigid cage or bracket extending upwardly from the proximal end32, which is fixed to the central portion11of the base10. The support bracket30has an opening36along one side of the support bracket, and the opening is arranged and configured to receive the mounting post16and the proximal end portion22of the support20therein while in the erect position. As shown in the example ofFIGS.1and2, the support bracket30and retainer26share the opening36along a common side of the support bracket. The retainer26thus may hold the mounting post16and/or the support20in the erect position with respect to the support bracket30when moved to the erect position, such as shown inFIG.9.

As a further example, the retainer26includes a latch38adapted to hold the support20in the erect position. The latch38may be implemented as a locking mechanism, pin, pawl, clamp or any other structure arranged and configured to hold the support20in the erect position with respect to the base10. For example, the latch38includes spaced apart retaining arms that are mechanically biased (e.g., by springs) toward each other and include shoulder portions configured to snap-fit and lock the elongated support20when moved to the erect position. The retainer26can also include an actuator40adapted to release the support20from being held by the latch38, such as by moving the spaced apart arms of the latch away from each other. For example, responsive to movement of actuator40from a lock position to a release position, retaining arms of the latch38are moved away from the each other to enlarge the opening36. Thus, when the actuator40is in the release position, the latch38is configured to allow the support20to move through the opening36between the erect position (e.g., upright orientation within the support bracket30) and the prone position (e.g., on the ground or other surface).

As described herein, the support20can be moved between its prone and erect positions manually or in a mechanically assisted manner. An example of a manual approach to move the support is one or more persons applying physical force to guide the support20and/or mounting post16(e.g., using their hands without mechanical or powered assistance) from the prone position to the erect position or from the erect position to the prone position. The manual approach may be implemented while the proximal end of the support is coupled to the mounting post, as described herein, as well as in the absence of a mounting post. An example of a mechanically-assisted approach to move the support20includes use of a hoist50configured to apply a physical force to move (or help move) the support between respective prone and erect positions.

For example, with reference toFIGS.2and7-9, the artificial Christmas tree200includes a hoist50. The hoist50can be coupled to the base10and/or the support20. The hoist50is adapted to move the support20between the prone and erect positions, as described herein. In an example, the hoist50includes a winch52and a flexible elongated member54. The flexible elongated member54can be implemented as a rope, a cord, wire or a cable or other flexible member having sufficient flexibility and tensile strength to support the weight of the elongated support20as it is moved between prone and erect positions by the winch52.

In an example, the winch52is coupled to the base10, such as attached to the support bracket30. In other examples, the winch52can be coupled to other parts of the base10. As an example, the winch52can be implemented as a mechanical winch (e.g., hand winch) that includes a spool56and a crank58, such as shown inFIG.2. In another example, the winch52may be implemented as a powered winch (e.g., powered by electric, hydraulic, pneumatic and/or another drive mechanism) in which the rotation of the spool56is driven in response to user-actuation of a control button or switch. The direction in which the spool56is rotated about an axis thereof controls whether the flexible elongated member54is being wound onto the spool56(to decrease the length of the flexible elongated member) or is unwound from the spool56(to increase the length of the flexible elongated member).

For example, as shown inFIGS.7and8, the flexible elongated member54extends from the winch52and is coupled to the support20at an intermediate location59of the support between its proximal and distal end portions22and24. The intermediate location59may be spaced from the proximal end portion22of the support a distance that is approximately equal to (though it may be more or less than) a height of the support bracket30. Thus, when the support20is in the erect position and retained within the support bracket30, such as shown inFIG.9, the location59is adjacent but spaced away from (e.g., above) the distal end34of the support bracket30, and the latch38. A connector60can be coupled to support20at the intermediate location59of the support20. In the examples shown inFIGS.7and8, a collar62is coupled around (partially or entirely around) the support20at the intermediate location59, and the collar62includes the connector60. The collar can be implemented as a strap, a sleeve, a clamp or other structure that may be permanently or removably coupled to the support to hold the connector60at the location59. In another example, the connector60can be coupled directly to the support20at the intermediate location59, such as by a mechanical fastener (e.g., nut and bolt, screw, rivet, etc.), adhesive bond, weld or the like. Thus, the connector60may be permanently coupled to the support20or be removable from the support. In yet another example, the flexible elongated member54is coupled to the support20at the intermediate location without the connector60, such as by looping a free end portion of the flexible elongated member54around the support20and attaching the free end portion with another part of the flexible elongated member54at the location59.

By way of further example, the hoist50can also include an arrangement of one or more pulleys64that can be coupled to the base10, such as at or near the distal end34of the support bracket30. The pulley64thus can be configured to support movement and change of direction of the flexible elongated member54between the winch52and the location59(e.g., connector60) where the flexible elongated member54is coupled to the support20. As mentioned, the winch52is adapted to change the length of the flexible elongated member54between the winch52and the support20to thereby move the support between the prone and erect positions, as shown inFIGS.7-9. While in the examples disclosed herein, the hoist50includes the winch52, in other examples, the winch52may be omitted from the hoist, and hoist include the flexible elongated member54and/or the arrangement of one or more pulleys64. In such example, the flexible elongated member54can be manually or otherwise pulled through one or more pulleys64to move the support20to a desired position. One or more rollers can also be used to facilitate movement of the flexible elongated member54relative to the support20. After being moved to the erect position, the support20can be fixed in place, such as by tying or otherwise securing the flexible member54with respect to the base10.

In some examples, one or more tree topper66may be attached at the distal end portion24of the support20. For example, prior to moving the support20to the erect position, the tree topper can be coupled at the distal end portion24, as shown inFIG.6. The coupling may further be configured to provide electrical power to the tree topper66and/or other associated decorations. For example, the topper66includes a tree topper (e.g., a star, angel or other ornamental topper). Additionally, or alternatively, the topper66can include a top set of respective tree branches with needles and having a general conical shape arranged and configured to form a continuous tree when a top tree frame section (e.g., to which branches have already been coupled) is hoisted longitudinally to its final assembly position at or near the distal end portion24of the support, as disclosed herein (see, e.g.,FIG.17). Respective branches may be coupled at the top of the support20separately or may be an integrated set of top branches for the artificial Christmas tree.

The artificial Christmas tree200includes a plurality of frame sections70,130,140and150adapted to be assembled to form a tree frame72, such as shown inFIGS.10-16. When assembled, each of the frame sections70,130,140and150can have a shape that is cylindrical, frusto-conical or a frame section may include a combination of cylindrical and frusto-conical portions. Thus, when the frames sections are coupled together, as disclosed herein, they form a tree frame for the artificial Christmas tree200, so that the tree can have a generally conical shape, such as the artificial Christmas tree shown inFIG.17. However, because the frame sections are separate, the systems and methods disclosed herein can be used to form an artificial Christmas tree having virtually any shape or combinations of shapes, including cylindrical, conical, ellipsoidal, polyhedral, spherical and semi-spherical to name a few.

In the examples ofFIGS.10-16, the frame sections70are moveable in the longitudinal direction above the assembly location, such as along the length of the support20. For example, a given frame section70has proximal and distal ends74and76spaced longitudinally apart from each other. The proximal end74of a given frame section70is adapted to be coupled to a distal end76of another frame section. In this way, longitudinal movement of the given frame section70along the support20causes corresponding axial movement of each other frame section (e.g., frame sections130,140and/or150) to which the given frame section is coupled.

As shown in the example ofFIGS.10and11, the frame section70includes one or more annular brackets (e.g., a collar portion)78configured to surround the support20. The annular brackets78has an inner diameter that at least approximates an outer diameter of the support20. A radially outer portion80of the frame section70has an inner diameter that is greater than the inner diameter of the annular brackets78. One or more braces82extend between the annular brackets78and the radially outer portion80of the respective frame section70.

As shown in the example ofFIG.10, to facilitate coupling respective frame sections70around the erect support, each respective frame section includes two or more annular sector portions84and86configured to be coupled together around the support20. An abutment, demonstrated at88, between the respective sector portions84and86can extend longitudinally between the axially spaced apart ends74and76of the frame section70. The two annular sector portions84and86may be coupled together along each abutment88by fasteners91arranged and configured to mechanically join the annular section portions together, such as shown inFIGS.10and11. Examples of fasteners91that may be used, individually or in combination, include nuts and bolts, locking pins, tape, zip ties, magnetic couplings, Velcro, or other fasteners arranged and configured to join the sector portions84and86together.

By way of further example, a sum of angles that the annular sector portions84and86of each respective frame section70,130,140,150span is 360 degrees so as to circumscribe the elongated support20. In the example ofFIGS.10-11, the frame section70includes two annular sector portions84and86that each spans an equal angle, such as approximately 180 degrees. In other examples, the annular sector portions for a respective frame section may be asymmetric, in which the angles that each annular sector portion spans are different from each other. Additionally, while the example frame sections70and130shown inFIGS.10-11includes two annular sector portions, one or more other frame sections140and150can include more than two annular sector portions (e.g., 3, 4, 5 or more annular sector portions), each of which may span the same or different angles. The number of annular sector portions in a respective frame section can depend on the outer diameter of the frame section. For example, larger diameter frame sections (e.g., lower frame sections) that are closer to the surface on which the base10is placed may have a larger number of annular sector portions than smaller diameter frame sections(e.g., upper frame sections) that are further from the surface on which the base10is placed. The number of annular sector portions for a given frame section70thus may further be designed to facilitate storage and/or transport.

As a further example, with reference back toFIGS.2and4, the artificial Christmas tree200can include an additional hoist90coupled to the base10, such as at or near the lower end32of the support bracket30. The hoist90can also be coupled to one or more frame sections and adapted to move one or more of the frame sections along the support20in a longitudinal direction of the tree frame72above an assembly location. The hoist90can be implemented as including any device or combination of devices, including manually operated, electrically and/or pneumatically driven hoists, configured and arranged to move respective frame sections70,130,140,150longitudinally above the assembly location. In one example, the hoist90also includes a connecting element that extends from a distal end of the support20that is configured to couple to and move the respective frame sections70,130,140,150longitudinally above the assembly location along the support20(e.g., by hoisting from above). In another example, the hoist is configured to lift the respective frame sections70,130,140,150from below (see, e.g.,FIGS.22-24). In an example, the hoist90is separate from the hoist50that is adapted to move the support between its prone and erect positions. In another example, the hoist90may use some of the same parts as the hoist50.

As described herein, the artificial Christmas tree200and related methods allow a user to attach tree features to respective frame section of the tree without requiring the use of ladders or other specialized equipment. The tree frame72, as formed by respective frame sections70,130,140and150, has an outer frame portion adapted to support artificial tree features83. The artificial tree features83can include branches, ornaments, lights and/or other decorations. Some or all the ornaments, lights and other decorations may be coupled to respective branches before the branches are attached to the respective frame sections70. Alternatively, some or all of the ornaments, lights and other decorations can be coupled to the branches during assembly of the artificial Christmas tree, such as after the branches are attached to the respective frame sections70.

As shown in the example ofFIG.12, tree features83can include branches with an arrangement of artificial foliage (e.g., needles or other leaves), ornaments, lights and other decorations. Such tree features83can be coupled to a respective frame section70,130,140,150prior to hoisting the frame section longitudinally towards the distal end portion24of the support20. For example, the hoist90can be used to position the frame section at desired height along the support to facilitate coupling tree features83to respective frame sections. In the example ofFIG.12, tree features83are coupled to the frame braces82by fasteners85after frame section70has been coupled to the support20. The fasteners85can be implemented as nuts and bolts, screws, pins, ties, and/or other fasteners arranged and configured to couple respective tree features to the frame sections. In some examples, some or all tree features83could be coupled to the frame section even before the frame section has been coupled around the support.

In some examples, the elongated support20can include one or more guides extending longitudinally along the support20. The one or more guides (e.g., passages) are configured to enable movement of one or more flexible elongated members98,100and/or electrical wires through or along the support20to facilitate operation of the hoist90, such as disclosed herein. For example, an electrical wire can be coupled between the tree topper66and extend through the guides to a source of electrical power. In another example, there can be one guide for each of the flexible elongated members98,100, or a respective guide may be shared by the flexible elongated members98,100. For example, the support20is hollow and thus has a passage (e.g., lumen)92extending longitudinally through the support to define the respective guide. The passage92has openings94and96at or near each of the respective proximal and distal end portions22and24of the support20. The guide passage92can have an internal diameter sufficient to receive one or more of flexible elongated members and/or other members (e.g., electrical connectors, conduits, etc.) within the passage.

The flexible elongated members98,100, which can form part of the hoist, can be implemented as ropes, cords, wires, cables or other flexible member having sufficient flexibility and tensile strength to support the weight of the frame sections as they are moved along the support20by the hoist90. While two flexible elongated members98,100are shown in the examples ofFIGS.4-13, different numbers (e.g., a greater or lesser number than two) of flexible elongated members can be used in other examples as part of the hoist90

As shown in the example ofFIGS.9and10, a portion of each of the flexible elongated members98,100extends from the distal end portion24of the support20to terminate in a respective end102,104. The ends102,104can include respective connectors106,108configured to couple the flexible elongated members98,100to one or more frame sections70, such as for hoisting respective frame sections along the support, such as disclosed herein (see, e.g.,FIGS.11-16). In other examples, namely where a brake apparatus has been included within a given frame section70, the connector ends may be coupled to the brake (see, e.g.,FIGS.18-20). Another portion of the flexible elongated members98,100may extend into and through the support20. The hoist90is configured to adjust the length of the flexible elongated members98,100that extends from the distal end portion24of the support20to control the position of one or more frame sections along the support20.

As a further example, with reference toFIGS.2and4, the hoist90can include a winch110, the flexible elongated members98,100, another flexible elongated member112and an arrangement of pulleys114,116,118and119. The winch110is coupled to the base10, such as coupled to the support bracket30. The pulleys114and116are coupled to the support20near the opening96at the distal end portion24of the support20. For example, the pulleys114and116may be mounted at diametrically opposed sides at the distal end portion24and configured to help keep the end connectors and flexible elongated members98,100separated along opposing exterior sides of the support20. While two pulleys114and116and associated flexible elongated members98,100are shown, any number of one or more flexible elongated members and respective pulleys could be used in other examples. The pulley118is coupled to the central portion of the base10and aligned with the opening94near the proximal end portion22of the support20when the support is retained (e.g., by retainer26) in the erect position. The pulley119is also coupled to the base10, such as aligned with the winch110. For example, the pulleys118and119are configured to support movement and change of direction of the flexible elongated member112between the support20and the winch110.

As shown inFIG.4, the winch110includes a spool120that rotates in a respective direction to control winding or unwinding a length of the flexible elongated member112from the spool. For example, the flexible elongated member112extends from the spool120of the winch110, passes over pulleys118and119, and is coupled to the flexible elongated members98,100. For example, a distal end113of the flexible elongated member112is coupled to respective ends proximal122,124of the flexible elongated members98,100(e.g., within passage92of the support20). In another example, the flexible elongated members98,100can be a formed of a single length of the flexible elongated member, and the distal end of the flexible elongated member112is coupled to a midpoint (at the location of ends122and124) of the flexible elongated member, such as by connector128.

The winch110may be a manual winch or a powered winch, such as described herein. In the example ofFIGS.1-14, the winch110is shown as an electrically-powered winch configured to control the rotation of the spool120in response to user-actuation of a control button or switch of a control device126. The use of an electrically powered winch110facilitates hoisting the frame sections longitudinally along the support, and further allows a user to continuously or intermittently adjust the height of respective frame sections while adding and/or removing tree features83. In an example, the control device126can be a remote control device that is physically or wirelessly coupled to a drive mechanism for controlling the rotation of the spool120. While the hoist90is shown inFIGS.1,2and4-16to include the winch110to adjust the longitudinal position of the frame sections70, in other examples, the winch could be omitted from the hoist90. The longitudinal position of the frame sections70thus could be adjusted manually (e.g., by hand) along the support20without use of a winch, and one or more flexible elongated members could be secured (e.g., with respect to the base10) to hold the length at a desired position during assembly and disassembly of the artificial Christmas tree, including when attaching and removing tree features83.

By way of further example, the continued assembly of the artificial Christmas tree200is disclosed with reference toFIGS.10-16. For example, after some or all respective tree features83have been coupled to the first frame section70, the first frame section70is moved longitudinally along the support20toward the distal end portion24of the support. For example, the hoist90is used to move the frame section70above the legs12,13by an amount sufficient to place a next frame section130beneath the frame section70(e.g., in a space between the legs of the base and the proximal end74)

A next frame section130is coupled around the support20beneath the preceding frame section70(e.g., between the legs of the base and first frame section70. The frame section130may include two or more annular frame sectors, such as described with respect toFIG.10. For example, the frame section130includes two annular sectors that each spans 180 degrees. The frame sectors of the frame section130are coupled together by fasteners around the support below the frame section70, such as described herein with respect to frame section70. In the example ofFIG.13, the frame section130is in the shape of a conical frustum having spaced apart proximal and distal ends132and134and longitudinally extending braces136between the ends. The distal end134has a smaller diameter than the proximal end132. The distal end134has the same diameter and is configured to abut the proximal end74of the preceding frame section70to facilitate connecting the frame sections70and130together.

For example, the distal end134of the frame section is coupled to the proximal end74of the preceding frame section70by fasteners91arranged and configured to mechanically join the respective frame sections together, such as shown inFIG.13. Examples of fasteners91that may be used to couple frame sections70and130together include one or more of nuts and bolts, locking pins, tape, zip ties, magnetic couplings, Velcro, or other fasteners arranged and configured to join the frame sectors84and86together. The type of fasteners91further may be selected according to expected loads to be experienced by the respective fasteners, which may vary depending on wherein the tree assembly the fasteners are used. Tree features83can be coupled to the braces of the frame section130, such as disclosed with respect toFIG.12to form a partially assembled artificial Christmas tree, as shown inFIG.14.

As shown inFIG.15, the assembly comprising tree frame sections70and130is moved longitudinally along the support20toward the distal end portion24of the support, such as disclosed herein (e.g., manually or using winch). With the proximal end132of the preceding frame section130raised sufficiently above the base10, a next frame section140is coupled around the support20beneath the preceding frame section130, as shown inFIG.15. In the example ofFIG.15, the frame section140is in the shape of a conical frustum. For example, the frame section140includes multiple annular sectors that collectively span 360 degrees and are coupled together along respective abutments (e.g., by nuts and bolts or other fasteners) to form the conical frustum shape. The frame section140includes a proximal end142and an opposing distal end144and braces extending longitudinally between the respective ends. The distal end144has a smaller diameter than the proximal base end142. For example, the distal end144has the same size and is configured for coupling to the proximal end132of the preceding frame section130. With the distal end144aligned with the end132in an abutment, the respective frame sections130and140can be coupled together (e.g., by nuts and bolts or other fasteners), such as described herein. Tree features83can also be coupled to the frame section130, such as disclosed with respect toFIGS.12, for forming artificial Christmas tree. As described herein, the height of the frame section140can be adjusted to a desired height during application of tree features (e.g., by hoist90, such as using remote control126).

As shown inFIG.16, the frame assembly comprising frame sections70,130and140is moved longitudinally along the support20toward the distal end portion24of the support, such as disclosed herein (e.g., manually or using winch). With the proximal end142of the preceding frame section140raised sufficiently above the base10, the next frame section150is coupled around the support20beneath the preceding frame section130, as shown inFIG.16. For example, the frame section150includes multiple annular sectors that collectively span 360 degrees and are coupled together along respective abutments (e.g., by nuts and bolts or other fasteners) to form a conical frustum shape. The frame section150includes a proximal end152and an opposing distal end154and respective braces extending longitudinally between the respective ends. The distal end154has a smaller diameter than the proximal end152. For example, the distal end154has the same size and is configured for coupling to the proximal end142of the preceding frame section140. With the distal end154aligned with the end142in an abutment, the respective frame sections140and150can be coupled together (e.g., by nuts and bolts or other fasteners), such as described herein.

In this example ofFIG.16, the frame section150is designed as the last frame section for artificial Christmas tree200being assembled. Accordingly, the height of the frame section140can be adjusted (e.g., by hoist90, such as using remote control126, or other means) to a desired height to facilitate application of tree features, if there is still room to lift the frame section150along the support. Tree features83can also be coupled to the frame section150, such as disclosed herein to form the final artificial Christmas tree200, such as shown inFIG.17. Additionally, to improve stability of the final artificial Christmas tree200, notches158are formed in the proximal base end152. The notches158are arranged and configured to allow legs12or13to be received in respective notches so that the proximal end152portion of the base frame150between the legs can rest directly on the ground (or other surface on which the base10is placed). Other frame sections140,130or70could include similarly configured notches158, such as in situations when they might be used as the lower-most frame section of the artificial Christmas tree200.

After the artificial Christmas tree200has been assembled, the guy wires25can be removed as shown inFIG.17. If desired, the telescoping leg portions13can be retracted or removed from the base10. The main legs12can remain in place or also can be removed. In this way such support features will not detract from the aesthetics of the fully assembled tree.

The artificial Christmas tree200further can include electrical lines and connectors (e.g., along an interior passage of the respective frame sections and/or along an exterior of the frames—not shown). The electrical lines and connectors are configured to supply electrical power to lights or other electrically powered decorations on the branches that are attached to the frames to receive electrical signals for operation. For example, plug-type electrical connections may be made between adjacent frame sections when connected together.

The sizes and number of respective frame sections can vary depending on the length of the artificial Christmas tree200being assembled. In an example, the artificial Christmas tree is a tall tree having a height of at least ten feet. In other examples, the tree is a tall tree having height of at least twenty feet, at least thirty feet, at least sixty feet or higher. The systems, trees and methods of assembly disclosed herein are equally applicable to an artificial Christmas tree having any height.

The artificial Christmas tree200may also be disassembled, such as by performing the sequence shown inFIGS.5-17in a reverse order. For example, the guy wires25may be reattached and the telescoping legs extended to provide increased stability during the disassembly process. The branches can be removed from lowest installed frame section, and the frame section can be disconnected from its preceding frame section and removed from the artificial Christmas tree200. The group of remaining frame sections is lowered toward the base10and the disassembly process is repeated until all the frame sections have been removed. The branches may remain attached or they can also be removed. After the frame sections have been removed, the elongated support20is moved from its erect position to its prone position, and the support can be disconnected from the base10. The base, frame sections, tree features, flexible elongated members and other parts and equipment may be transported and stored in a suitable storage location.

In some examples, the artificial Christmas tree can include a brake system250. The brake system250is coupled to at least one of the frame sections, such as an uppermost frame section70. In another example, one or more respective frame section may include a respective brake system. For example, the brake system250may be coupled within the first frame section70and one or more other frame sections may be connected directly or indirectly to the first frame section. The brake system250is adapted to actuate braking responsive to free-fall axial movement of at least one of plurality of frame sections in the longitudinal direction along the support20, such as in the unlikely event that the frame section becomes disconnected from the hoist90.FIGS.18,19and20show an example of a brake system250.

In the example ofFIG.18, the brake system250includes brake apparatuses252and254coupled to frame sector portions84and86of the frame section70. Each brake apparatus252,254can reside opposite sides of the elongated support, when the frame sectors are coupled together around the support, as disclosed herein. Each brake apparatus252,254includes a respective braking member260,262. The braking members260and262are mounted within brake housing portions256,258, and are biased radially inwardly toward the support20(e.g., by one or more springs276,278—not shown inFIG.18). For example, braking members260and262are coupled to brake housing portions256and258by a coupling (e.g., pivot member or other structure) arranged and configured to enable movement of braking members into and out of engagement with the support20. The flexible elongated members98and100can be configured to hold braking members260and262away from the support20when the flexible elongated members are taut. In the example shown inFIG.19, when the flexible elongated members98and100provide tension to support the frame section70, the flexible elongated members98and100engage an arm, pin, roller or other structure, shown at272and274, to move and hold the braking members260and262out of engagement from the support20(see, e.g.,FIG.19). When the tension is removed (e.g., in response to a cable snapping or otherwise released), the springs276and278drive respective braking members260and262into engagement with the support20(see, e.g.,FIG.20), thereby stopping the downward movement of the frame section70as well any other frame sections that may be coupled to the frame section. The brake apparatus252,254can also include a wheel (or other guide)264,266arranged and configured to hold the brake apparatus at a prescribed alignment with respect to the elongated support20and to facilitate longitudinal movement of the frame section70along the support, including during assembly and disassembly.

For example, so long as the flexible elongated members98,100are applying force in a direction of arrow A3 (shown inFIG.18), which results in sufficient tension in the flexible elongated members98,100, the brake system250is configured to permit substantially free longitudinal movement of the frame section70along the elongated support20. The weight of the first frame section (individually or in combination with any other connected frame sections) can provide sufficient tension on the flexible elongated members98,100, which holds the braking members260and262away from the support20to enable the longitudinal movement of the frame section(s) along the support20. If the flexible elongated members98,100no longer apply force in the direction A3 so the tension is removed or the braking apparatus is otherwise activated, the braking members260and262are actuated to apply frictional and/or other forces to the support20to decelerate and/or to prevent further axial movement of the brake system250and each frame section that is operatively coupled to the brake system.

FIGS.19and20depicts an example of the brake system250with parts of the frame section70and brake system removed to show a portion of each brake apparatus252,254coupled around the elongated support20. InFIG.19, the flexible elongated members98,100are taut through each brake apparatus252,254in response to force applied upwardly on the flexible elongated members98,100. Thus, flexible elongated members98,100engage respective pins272,274to move each braking member260,262away from the support20. As a result, the brake system250is configured in a released position to allow for substantially free movement of the frame section70along the support20, as described herein.

In the example ofFIG.20, the brake system250is activated in response to terminating the application of upward force on the flexible elongated members98,100. As a result of the tension in the flexible elongated members98,100being removed, springs276and278drive the braking members260and262radially inwardly to engage the elongated support20and apply force to the support20for braking the frame section70(e.g., along with any other frame sections coupled to such frame section). For example, the braking system250can be configured to automatically actuate in response to the tension in the flexible elongated members98,100being removed. The brake apparatus250thus is free to move axially along the support20while there is tension in the flexible elongated members98,100(e.g., due to upward force being applied). In response to terminating the application of force on the flexible elongated members98,100, the brakes252,254are actuated to stop axial movement along the support20.

FIG.21is a flow diagram depicting an example of a method300to assemble an artificial Christmas tree, such as the artificial Christmas tree200. Accordingly, the method300also refers to artificial Christmas tree200and its assembly or disassembly, as shown in FIGS.1-20. At302, the method300includes positioning the base10at a desired location where the tree is to be displayed. With the base in position, legs may be coupled and/or extended from the base10(see, e.g.,FIG.5).

At304, the method includes erecting the elongated support of the tree so a distal end portion of the support is above an opposite proximal end portion of the support distal end portion of the support is above the base. For example, a hoist50is used to move the support20from the prone position to the erect position (see, e.g.,FIGS.7-9). The support20can be coupled to the base10to enable movement of the support between the prone position and the erect position. For example, the base10includes a mounting post16moveable between respective prone and erect positions thereof, and the proximal end portion of the support is coupled to the mounting post prior to erecting the support at304. When the support has been erected, the support can be retained the erect position with respect to the base, such as by retainer26(see, e.g.,FIG.9). As disclosed herein, the support20can be moved to the erect position (e.g., with or without the hoist50) prior to any frame sections being coupled around the support. In a further example, one or more tree toppers66can be coupled at the distal end portion of the support prior to erecting the support at304.

At306, a first frame section is positioned relative to the support. For example, the first frame section70can be coupled around the elongated support20by coupling respective frame sectors84and86together (see, e.g.,FIGS.10-11). At308, the method300also includes moving the first frame section along the support toward the distal end portion of the support. For example, a hoist90, which is coupled to the support, can be used to move the first frame section70along the support20. The support20further can include passage extending longitudinally through the support with openings94and96near each of the proximal and distal end portions22and24of the support. The hoist90can include a winch, an arrangement of pulleys and a flexible elongated member that extends through the passage of the support and is coupled to the first frame section. A length of one or more flexible elongated members98,100thus can traverse the passage when moving one or more frame sections at308by using the hoist.

Additionally, in some examples, prior to raising any frame section along the support more than a predetermined distance sufficient for placing a next frame section around the support between the base and a preceding frame section, the method300includes attaching tree features83to the frame section. This can include attaching branches to the one or more frame sections and/or decorating at least some of the branches. As an example, a user may hoist the preceding frame section(s) a few feet off the ground to facilitate attaching branches and decorations to such preceding frame section. In this way, the user can attach branches and decorations while standing instead of kneeling or sitting on the ground adjacent the frame section. In some examples, the height may be adjusted (e.g., up or down) throughout the process of attaching branches and decorating. Once branches and decorations have been applied to a given frame section, the given frame section may be move upwardly along the support a distance that is greater than or equal to the predetermined distance to enable the next frame section to be attached. As described herein, the branches and/or decorating can be implemented without requiring use of a ladder or other extension equipment.

At310, a next frame section is positioned beneath the preceding frame section. At312, the next frame section is coupled to the preceding frame section. For example, after the first frame section70has been decorated, the first frame section70can be moved longitudinally along the support20to provide space between the base10and the proximal end74of the first frame section for the next frame section130(see, e.g.,FIGS.11-13). Frame sectors of the next frame section130can be coupled to each other around the support, and the distal end134of the next frame section130can be coupled to the proximal end74of the first frame section70(see, e.g.,FIG.13). To facilitate coupling the ends74and134of the frame sections70and130together, the first frame section70may be lowered (e.g., by hoist90) onto the next frame section130.

At314, a determination is made whether there are any additional frame sections that are to be assembled as part of the tree. If additional frame sections are to be used (yes), the method returns from314to308to repeat the steps at308,310and312for each subsequent frame section to form the artificial Christmas tree. Because the proximal end of a given frame section is adapted to be coupled to a distal end of another frame section, movement of the given frame section along the support (e.g., by hoist90) causes corresponding movement of each other frame section to which the given frame section is coupled. When it is determined at314that no additional frame sections are to be added, the method ends at316.

As disclosed herein, the order of the method300may be reversed to disassemble the artificial Christmas tree. For example, disassembly can include removing each frame section from the support, moving the remaining frame sections in a longitudinal direction toward the base10and repeating the removal of frame sections until all have been removed from the support. Then, the support can be moved from the erect position to a prone position, such as in which the support is placed on the ground or other surface structure near the base. As further disclosed, the artificial Christmas tree can be configured as a kit having a prescribed set of frame sections that can vary depending on a height of the tree. The elongated support20further can include multiple longitudinal support portions, which can be coupled together axially between the proximal and distal end portions of the support (see, e.g.,FIG.3). In some examples, such as for very tall and/or heavy trees, the tree can include a brake system (e.g., brake system250). In an artificial tree that includes a brake system and in the unlikely event that one or more frame sections were to fall downwardly along the support (e.g., if the flexible members98,100were to release, snap or otherwise unable to provide tension to hold the frame section70), the method300further can include automatically actuating the brake system in such event. In response to being actuated, the brake system can decelerate or prevent movement of the frame section(s) along the support in a direction from the distal end portion of the support to the proximal end portion of the support (see, e.g.,FIGS.18-20).

As used herein, the term “includes” means includes but not limited to, the term “including” means including but not limited to. The term “based on” means based at least in part on. Additionally, where the disclosure or claims recite “a,” “an,” “a first,” or “another” element, or the equivalent thereof, it should be interpreted to include one or more than one such element, neither requiring nor excluding two or more such elements.

As described herein, an artificial Christmas tree can be assembled and disassembled by hoisting respective frames in a longitudinal direction over an assembly (or disassembly) position. The hoisting can be implemented by lifting respective frame sections from above, such as described with respect toFIGS.4-17and21. In another example, the hoisting can be implemented by lifting or lowering respective frame sections from a hoist located within the tree frame, such as described with respect toFIGS.22-24. Accordingly, those skilled in the art will appreciate various configurations of hoists that can be implemented to raise and lower frame sections for assembly and disassembly based on this disclosure.

FIGS.22-24depict an example of a central base400that can be part of an artificial Christmas tree200, such as disclosed herein. For example, the central base400can be located at a central position within a frame of the artificial Christmas tree200being assembled or disassembled. In the example ofFIGS.22-24, the base400includes a hoist402arranged and configured to move one or more frame sections in a longitudinal direction above an assembly (or disassembly) position. For example, the hoist can contact part of a lower frame section and lift (or lower) the frame section, along with any frame sections coupled to it, from below. The base400includes a central base portion404that can be placed on a surface (e.g., ground) at a desired assembly location, which typically also is the display location. The hoist402can be arranged at the central base portion404. One or more wheels (not shown) can be coupled to the central base portion404to facilitate movement of the base400across the surface, such as described herein.

The base400can also include a number of legs406extending outwardly from the central base portion404of the base400. The legs406may be coupled to the central base portion404by one or more fasteners, as described herein. The legs406are configured to provide additional stability, such as by increasing the effective diameter of the central base portion. In some examples, the legs406may include telescoping leg portions408to provide adjustable lengths that may be set by a user. As disclosed herein, the telescoping leg portions408are adapted to provide additional support and stability by further increasing the effective diameter of the base400, such as during assembly and/or disassembly of the tree200.

In the example ofFIGS.22-24, the hoist402is a lift mechanism that includes an elongated central barrel portion410extending outwardly from (e.g., orthogonal to) the central base portion404to terminate in a distal end412thereof. The central barrel410can be fixed with respect to the base support portion404(e.g., by welding and/or use of fasteners). The central barrel410is adapted to support an elongated rod (e.g., a piston rod)414, which is movable with respect to the central barrel410. The rod414thus extends a variable distance from the distal end412of the barrel410to terminate a distal rod end416. The central barrel410includes one or more adjustment mechanisms arranged and configured to move the rod414in a longitudinal direction (e.g., axially) relative to the central barrel, to thereby adjust the distance that the rod extends from the central barrel. That is, the hoist402is moveable between its compressed position (shown in solid lines) and its extended position (shown in dashed lines) in a longitudinal direction of the tree frame, shown at A4, for raising and lowering frame sections, such as described herein.

The adjustment mechanism(s) can be coupled to a proximal end of the rod414(not shown) within the barrel410, and include mechanical, hydraulic, electrical, and/or electro-mechanical mechanisms configured to move the rod414relative to the barrel410. In some examples, the adjustment mechanism of the hoist402is controllable by an actuator, shown at418, which is coupled to (e.g., part of) the hoist. The actuator418can be an electrical and/or mechanical actuator configured to implement desired movement of the rod with respect to the barrel410, namely to raise or lower the distal end416of the rod414. In an example where the actuator418implements electrical actuation, a controller420can be coupled to the actuator418and be adapted to activate or deactivate the actuator418responsive to a user input (e.g., by pressing a respective button on a human-machine interface of the controller420).

In the example ofFIGS.22-24, the hoist402includes an arrangement of arms422coupled to the distal end416of the rod414. The arms422can extend radially outwardly from the rod414and terminate in respective distal end portions424. The distal end portions424can be adapted to contact braces or annular support portions of a frame section. In one example, a support bracket (e.g., a curved or generally U-shaped bracket)426can be mounted at each of the distal end portion424. The support bracket426can be arranged and configured at the distal end portion424to grasp or hold a portion of a frame section during hoisting thereof, such as during assembly or disassembly of the tree200(see,FIGS.23and24). In some examples, the support bracket can swivel to facilitate alignment with braces or support portions of the frame sections. Additionally, or alternatively, straps (e.g., rubber, nylon or the like) or ties can be attached to the support brackets426or another part of the distal end portion424to help hold the frame sections in place with respect to the arms422, such as when the frame sections are being lifted up or down by the hoist402.

In some examples, the distal end portion424of the arms422may be implemented as telescoping arms to provide variable arm lengths, which can be adjusted by a user according to the size of the frame section being hoisted. For example, the telescoping distal arm424may extend axially from the main part of the respective arms422. As shown in the examples ofFIG.22, the telescoping distal arm portions424are each moveable axially with respect to the respective main arms422in the direction of an arrow, shown at A4.

As a further example, the arms422can include proximal arm portions430that are coupled to the distal end416of the rod414. The proximal arm portions430can extend longitudinally from the distal end416of the rod414in a direction towards the central base portion404. The proximal arm portions430can also extend substantially parallel to and be spaced radially outwardly from an outer sidewall of the central barrel410. The main arm portions422can extend from the ends of the proximal arm portions outwardly away from the central barrel410. For example, the main arm portions422can extend transversely away from the ends of respective proximal arm portions430, such as at an angle ranging from about 70 degrees to about 110 degrees (e.g., about 90 degrees). The main arm portions422can be fixed to or integrally formed with the proximal arm portions430. Alternatively, the main arm portions422can be able to move longitudinally along the length of the proximal arm portions430, such as to adjust the height of the main arm portions (e.g., without actuating the hoist402).

One or more spacing collars432can be coupled to an intermediate location of the proximal arm portions430. The spacing collar432is arranged and configured to facilitate movement of the collar longitudinally along the central barrel410and, when the hoist402is extended a sufficient length, also along the rod414. For example, the collar432is formed of a rigid material and is configured to support the proximal arm portions430in a fixed arrangement and to space the arm portions430away from the outer sidewall of the central barrel410. A radially inner surface of the collar432can include a coating, bearings, rollers or other feature to facilitate its longitudinal motion along the barrel410and rod414during hoisting.

InFIG.23, a frame section440is shown being lifted above the surface at an assembly location. The frame section440can be any of a number of frame sections that can be coupled together to form the frame of the artificial Christmas tree200. The frame section440can include an arrangement of annular sectors or be implemented according to other configurations, such as described herein. The support brackets426can be arranged and configured to hold respective annular frame supports442of the frame section440, such as by adjusting the length of the respective distal end portions424to match the diameter of the frame supports442being held by the support brackets426. When positioning the support brackets426, the hoist402can be actuated to raise or lower the arms at an appropriate height for contacting the frame support442. As shown in the examples ofFIGS.23and24, the support brackets426can hold an intermediate (or upper) frame extension from a lower edge, and the frame can be strapped in place by one or more straps444. In other examples, the support brackets426can grasp other parts of the frame (lateral or vertical extending frame supports) from other angles such as from above or from the side. After the frame section440is secured to the support bracket426(or another part of the arm422), a user can control the actuator418to raise or lower the frame section for assembling and disassembling the artificial Christmas tree. For assembly, the hoist402is configured to lift a given frame section along with one or more other frame sections, if they have been already assembled into the tree, to provide sufficient height to insert a next frame section between the previous frame section and the ground. For disassembly, the hoist402is thus configured to attach to and lift a frame section that is above the lower-most frame section being removed, and after the lower-most frame has been removed, the previous frame section can be lowered onto the ground and the disassembly process repeated.

FIG.24show the artificial Christmas tree200at an intermediate stage of assembly or disassembly using the hoist402to raise or lower the frame sections440and450of the tree. For example, a second frame section450has its distal end aligned with and abutting the proximal end of the frame section440, and the respective frame sections440and450can be coupled together (e.g., by nuts and bolts or other fasteners), such as described herein. The process of adding or removing frame sections, including using the hoist402to raise or lower the frame section(s) as needed, can be repeated for each frame section until the process of assembling or disassembling the tree is complete. As shown inFIG.24, the tree200can include branches with an arrangement of artificial foliage (e.g., needles or other leaves)452, ornaments454, lights and/or other decorations456, which can be attached to one or more of respective frame sections440and450.

For example, with reference toFIGS.23and24, a method of assembling an artificial Christmas tree will be described. The method includes positioning a given frame section440of an artificial Christmas tree200at the assembly location. Frame sectors can be assembled together to form a frame section440around the base400, such as described herein. The height and length of the arms422can adjusted to align the support brackets426with desired portions of the frame section440for lifting. Once in alignment (e.g., with support brackets holding the frame), the frame section(s) can be moved in the longitudinal direction above the assembly location, such as shown inFIG.23. The hoist402can be controlled (e.g., using the controller420) to move the proximal (bottom) end of the frame above the surface a distance at least equal to a height of a next frame section to be added.

A next frame section450can be assembled and positioned beneath the previous frame section440. The next frame section450can then be coupled to the previous frame section. For example, the previous frame section(s) can be lowered onto the next frame section450for attachment (e.g., by fasteners). A user can control the hoist402to move the first and second frame sections440and450, as a unit, in the longitudinal direction so the most recently attached frame section450rests on the ground (or on the legs406). While resting on the ground, the straps444can be loosened and removed from holding the frame section440, and the hoist lowered further. The distal end portions424can be adjusted to align support brackets426with a frame section of the lower (e.g., bottom) frame section450. During such alignment, the hoist402can be actuated so the support brackets426can contact and hold the frame support, and straps444can applied to secure the frame to the arms422. Once properly connected, the hoist402can be activated to move the frame sections, as a unit, longitudinally above the assembly location to provide sufficient space for the next frame section (if any). As mentioned, branches having an arrangement of artificial foliage (e.g., needles or other leaves)452, ornaments454, lights and/or other decorations456can also be attached to one or more of respective frame sections440and450prior to hoisting the frames for adding the next frame section. In some examples, lights can be coupled to at least some of the branches and electrical lines along the respective frame sections can be connected together to supply electrical power to the lights as well as other electrical features.

While the hoist402inFIGS.22-24is shown as a hydraulic-type lift, other types of hoists can be used in other examples, such as a scissor lift, a pneumatic lift, an accordion lift and the like. Additionally, by using the hoist402to lift from the bottom, the elongated central support (e.g., trunk)20can be omitted from the artificial Christmas tree. In other examples, the hoist402can be used with the support20, such as by appropriate adaptations to the hoist and/or support.

As used herein, the term “and/or” can include any and all combinations of one or more of the associated listed items.

It will be understood that when an element is referred to as being “on,” “attached” to, “connected” to, “coupled” with, “contacting”, “adjacent”, etc., another element, it can be directly on, attached to, connected to, coupled with, contacting, or adjacent the other element or intervening elements may also be present. In contrast, when an element is referred to as being, for example, “directly on,” “directly attached” to, “directly connected” to, “directly coupled” with, “directly contacting”, or “directly adjacent” another element, there are no intervening elements present. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “directly adjacent” another feature may have portions that overlap or underlie the adjacent feature, whereas a structure or feature that is disposed “adjacent” another feature might not have portions that overlap or underlie the adjacent feature.

Spatially relative terms, such as “under,” “below,” “lower,” “over,” “upper”, “proximal”, “distal”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms can encompass different orientations of a device in use or operation, in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features.

As used herein, the phrase “at least one of X and Y” can be interpreted to include X, Y, or a combination of X and Y.

It will be understood that, although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a “first” element discussed below could also be termed a “second” element without departing from the teachings of the present disclosure. The sequence of operations (or steps) is not limited to the order presented in the claims or figures unless specifically indicated otherwise.

Any of the described structures and components could be integrally formed as a single unitary or monolithic piece or made up of separate sub-components, with either of these formations involving any suitable stock or bespoke components and/or any suitable material or combinations of materials; however, the chosen material(s) should be biocompatible for many applications.

Though certain components described herein are shown as having specific geometric shapes, all structures of this disclosure may have any suitable shapes, sizes, configurations, relative relationships, cross-sectional areas, or any other physical characteristics as desirable for a particular application. Any structures or features described with reference to one aspect or configuration could be provided, singly or in combination with other structures or features, to any other aspect or configuration, as it would be impractical to describe each of the aspects and configurations discussed herein as having all of the options discussed with respect to all of the other aspects and configurations. A device or method incorporating any of these features should be understood to fall under the scope of this disclosure as determined based upon the claims below and any equivalents thereof.

What have been described above are examples. It is, of course, not possible to describe every conceivable combination of components or methodologies, but one of ordinary skill in the art will recognize that many further combinations and permutations are possible. Accordingly, the invention is intended to embrace all such alterations, modifications, and variations that fall within the scope of this application, including the appended claims.
