TECHNICAL FIELD

The present disclosure relates to the technical field of festival decoration products, and in particular, relates to a treetop support configured to fix a treetop decorative piece to a treetop of a Christmas tree.

BACKGROUND

Christmas trees are commonly used for festival decoration and ornament, and generally, various decorative pieces or ornaments, for example, color lights, color strips, and the like, may also be put on the Christmas tree. Treetop decorative pieces are also commonly used for the Christmas tree. Conventionally, treetops of the Christmas trees have substantially consistent shape and dimension (some differences may be present in terms of dimension between real trees and artificial trees). However, the treetop decorative pieces have different fixing bases depending on different designs and styles.

Typically, a dedicated fixing support is correspondingly arranged according to the specific shape of a treetop decorative piece to fix the decorative piece to the treetop of the Christmas tree. However, the conventional fixing support fails to particularly match with all types of treetop decorative pieces, or achieves a poor fixing effect even the fixing support is capable of fixing the treetop decorative pieces.

Therefore, it is necessary to develop a novel treetop support capable of matching with most of the treetop decorative pieces and achieving a good fixing and support effect.

SUMMARY

With respect to a convention treetop decorative piece, a connection portion configured to fix the treetop decorative piece to a Christmas tree is typically a conical structure, a cylindrical structure, a straight-rod structure, a clamp structure, a baby skirt internal support structure, or the like structure. In this case, a dedicated fixing portion is generally desired, or the connection portion merely adapts to a Christmas tree having a particular treetop structure. The present disclosure is intended to provide a treetop support applicable to a treetop of a Christmas tree to fix treetop decorative pieces of different shapes or dimensions to the treetop of the Christmas tree.

DETAILED DESCRIPTION

For better understanding of the present disclosure by a person skilled in the art and for more clear definition of the protection scope of the present disclosure, the present disclosure is described hereinafter in detail with reference to some specific embodiments. It should be noted that the specific embodiments construed for the present disclosure are only illustrated, which are merely a part of embodiments of the present disclosure. The specific and direct descriptions of the related structures are only for ease of understanding of the present disclosure, and various specific features are not intended to directly limit the practice of the present disclosure. Any customary selections and replacements made by a person skilled in the art under the concept of the present disclosure shall all be considered as falling within the protection scope of the present disclosure.

A treetop support is provided. The treetop support is applicable to a treetop of a Christmas tree to allow a treetop decorative piece to be fixed to the treetop of the Christmas tree by the treetop support. In this way, an object of decorating the Christmas tree is achieved.

Referring toFIG. 1toFIG. 3, the treetop support includes a support body100, and a support assembly200and an adjustment assembly300that are fitted on the support body. The support body100is configured to be fitted with a treetop of a Christmas tree to fit the treetop support assembly to the treetop of the Christmas tree. The support assembly200and the adjustment assembly300are both fitted on the support body100. The support assembly200is pivoted to present different fitting states such that different treetop decorative pieces are fixed to the treetop of the Christmas tree by the treetop support. The adjustment assembly300is displaceably fitted on the support body100to adjust a fitting state of the support assembly200with respect to the support body100.

The support body100includes a support rod110. The support rod110is in a rod or rod-like structure to achieve a critical support function.

The support assembly200includes a plurality of support members210. Each of the support members210is pivotably fitted on the support rod110. An outer surface of each of the support members210is formed as a support surface211. The support surfaces211form different angles with the support rod110due to pivoting of the support members210. The support surfaces211of the support members210collectively formed as a support plane of the support assembly200, such that the treetop decorative piece is fitted on the support plane. In addition, since a pivoting angle of each of the support members210with respect to the support rod110are adjustable, an angle of the support plane formed by the support surfaces211is also adjustable. In this way, the treetop support may adapt to treetop decorative pieces in different shapes and dimensions.

The adjustment assembly300is displaceably arranged along an extending direction of the support rod110. The adjustment assembly300includes an adjustment portion310. When the adjustment assembly300is displaced along the support rod110, the adjustment portion310is synchronously displaced correspondingly. In addition, the adjustment portion310is fitted on a bottom or an inner wall of each of the support members210, such that the support member210is pivoted with respect to the support rod110, and the angle between the support member210and the support rod110is also correspondingly increased or decreased. In this way, different conical support structures with different dimensions are formed to adapt to the treetop support having a conical or cone-like fixing connection portion. In addition, the support members210may also be such pivoted that each of the support members210is attached to the support rod110to form a support structure in a cylindrical shape or a prismatic shape such that the treetop support is folded and received, or may serve as a treetop support matching with a fixing connection portion in a cylindrical shape or with an clamp acting as a fixing connection portion.

When the treetop support adapts to a treetop decorative having different fixing connection portions, fitting between the treetop support and the treetop decorative piece is as follows.

Referring toFIG. 8, each of the support member210of the treetop support is pivoted by a suitable angle to form a cone-like support plane formed by four support members210, and the adjustment assembly300is rotated by a threaded structure with respect to the support rod110, and displaced to a suitable position and maintained at the position. In this case, an inner wall of each of the support members210is supported by the adjustment portion310of the adjustment assembly300. Still referring toFIG. 13, a treetop decorative piece600is provided with a conical fixing portion formed by spiraling of a linear portion, which is sleeved on a conical support surface of the treetop support member. Apparently, the treetop support is displaceable upward and downward along the support rod110by the adjustment assembly300, such that the support members210exhibits different angles of conical surfaces, and thus the treetop support adapts to various conical fixing portions having different angles of conical surfaces.

Referring toFIG. 14, by adjustment of the angles of conical surfaces, the treetop support may also be caused to adapt to inside of the skirt of a baby-shaped treetop support, such that the baby-shaped treetop support is fixed.

Referring toFIG. 15, when the support members210are in a folding and receiving state, the treetop support is formed to have a cylindrical upper structure. In this way, not only a folding state of the treetop support may be formed, but also a treetop decorative piece having a fixing connection portion with a cylindrical fixing inner cavity is fixed. In this case, the fixing connection portion having the cylindrical fixing inner cavity of the treetop decorative piece has an inner diameter greater than or equal to an outer diameter of each of the support members210, and a lower end of the fixing connection portion is supported by the adjustment portion310, such that the treetop decorative piece600is fixed.

Referring toFIG. 16, likewise, when the support members210are in the folding and receiving state, the treetop support may also employ a clamp as the fixing connection portion to fix the treetop decorative piece. In this case, the fixing connection portion of the treetop decorative piece600is a clamp602. One end of the clamp is clamped onto the support members210in the folding and receiving state to fix the treetop decorative piece600.

Therefore, based on different states formed by pivoting of the support members210with respect to the support rod110, the treetop support may match with the treetop decorative piece600fixed by a variety of configurations such as a fixing connection portion with a conical inner cavity, a skirt fixing connection portion, a fixing connection portion with a cylindrical inner cavity, and a clamp fixing connection portion.

In some embodiments, an end of the support member210is provided with a pivot shaft201, the support rod110is correspondingly provided with a shaft base. The pivot shaft201is fitted into the shaft base, such that the support member210is pivotably arranged with a position at an upper end thereof as a pivot shaft.

Referring toFIG. 3andFIG. 4, a top pf the support rod110is provided with a shaft base fixing cover120. The shaft base fixing cover120is fixed to the support rod110by a screw (not shown in the drawings). The shaft base fixing cover120and the support rod110are each provided with a half shaft base202, and the two half shaft bases202respectively arranged on the shaft cover fixing cover120and the support rod110cooperate with each other and form the shaft base after the shaft base fixing cover120and the support rod110are fixed to each other.

The top of the support rod110is further provided with a pivot hole203, such that an upper portion of each of the support members210is fitted into the pivot hole203, such that each of the support members210is pivotably fitted on the support rod110about the pivot shaft201.

Although the shaft base fixing cover120and the support rod110are fixed by the screw as illustrated inFIG. 5, other known connection techniques may also be employed, for example, snap-fitting, adhesive-bonding, or the like.

Referring toFIG. 2andFIG. 5, to lock each of the support members210when not being used, an upper end surface of the adjustment portion310is provided with a locking slot311. A lower end212of each of the support member210is fittable into the locking slot311, such that the treetop support may be formed as a relatively fixed integral structure when not being used. That is, when each of the support members210is pivoted to be attached to the support rod110to form a cylindrical shape, the lower end212of each of the support members210is locked into the locking slot311, such that each of the support members210fails to be freely pivoted.

Referring toFIG. 5, to enable each of the support members210to be automatically pivoted to a desired angle during adjustment of the treetop support, the adjustment portion310is provided with a guide surface313. The guide surface313is a conical surface or a curved surface, and outwardly acts on the lower end212of the support member210to achieve a guide effect. When the adjustment assembly300is displaced along the support rod110, for example, displaced from bottom to top, the lower end of the support member210is slided along the guide surface313and is automatically unfolded by the guide effect.

In addition, it is also feasible that the adjustment portion310is not provided with the guide surface313, as long as the treetop support is inverted during initial adjustment or each of the support members210is manually driven. In this case, an upper surface of the adjustment portion310is designed as a flat surface.

Referring toFIG. 5, for ease of operation of the adjustment assembly300, the adjustment assembly300further includes a hand-wheel portion320, which is arranged under the adjustment portion310. In addition, to enable the adjustment assembly300to be displaceably arranged with respect to the extending direction of the support rod110, the adjustment assembly300is hollowed out and formed as a cylindrical cavity312. The cylindrical cavity312is sleeved on the outside of the support rod110, such that the adjustment assembly300is displaceable upward and downward along the support rod110.

In some embodiments, an outer wall of the support rod110and an inner wall of the cylindrical cavity312are respectively provided with threaded structures fittable with each other, such that the adjustment assembly300is displaced upward and downward or positioned by rotation with respect to the support rod110. Specific parameters (for example, a pitch) of the threaded structures may be defined according to the actual needs, such that the adjustment assembly300achieves a suitable displacement distance in response to being rotated by 360 degrees, and is positioned at a corresponding position.

In some other embodiments, upward and downward displacement or positioning is achieved between the support rod110and the adjustment assembly300by thread engagement, and thus another equivalent alternative structure is achieved.

For example, the adjustment assembly300is freely displaceably sleeved on the support rod110and is locked and positioned by a locking mechanism, wherein the locking mechanism includes a locking slot113and a locking block (not shown in the drawings) respectively arranged on the support rod110and the adjustment assembly300. When the locking block and the locking slot113are separated from each other for unlocking, the adjustment assembly300is capable of being freely displaced to a desired position along the extending direction of the support rod110, such that the locking block is fitted into the locking slot113to lock the displacement of the adjustment assembly300along the support rod110, and thus the adjustment assembly300is positioned. In this way, each of the support members210exhibits a desired angle of conical surface.

The locking slot is preferably arranged on an outer surface of the support rod110along the extending direction of the support rod110. The adjustment assembly300is correspondingly provided with a locking block. When the locking block is fitted into the locking slot, the adjustment assembly300is displaced with respect to the support rod110along the extending direction of the support rod110and thus is locked and positioned. If the adjustment assembly300needs to be operated to be displaced with respect to the support rod110, the locking block needs to be operated to be separated from the locking slot. When the adjustment assembly is displaced to a suitable position, the locking block and the locking slot are fitted with each other again to achieve locking again. The structure of the locking block is known, for example, by arranging an elastic member on an inner wall of the cylindrical cavity312at one end and forming a locking block fittable into the locking slot at the other end.

In addition, when the adjustment assembly300is freely displaceable sleeved on the support rod110and is locked and positioned by the locking mechanism, the outer wall of the support rod110may also be further fitted with an inner wall314of the cylindrical cavity by friction. Specifically, by interference fitting between inner and outer diameters or an elastic piece mating structure, the adjustment assembly300is displaced or positioned along the extending direction of the support rod110. Nevertheless, when the friction between the outer wall and the inner wall is sufficiently great, the locking mechanism constituted by the locking slot and the locking block may be omitted.

Although the guide surface313is capable of causing each of the support members210to be automatically pivoted to a desired angle under the guide effect thereof, the guide effect is not effected during initial operations in a locking state. Further simplification of the operations and improvement of user experience, the treetop support further includes an unlocking assisting member130, which acts on each of the support members210at an initial state of unlocking, such that the support member210is pivoted to a desired angle, and thus the lower end of the support member210is unfolded and fitted with the guide face313.

Referring toFIG. 4, the unlocking assisting member130is arranged on the support rod110, which is arranged under the shaft base by a suitable distance, that is, arranged under the pivot shaft of each of the support member210. The pivot shaft refers to a pivot shaft formed when the support member210is pivoted about the pivot shaft201. Further, the unlocking assisting member130is protruded on a surface of the support rod110, such that each of the support members210is fitted, at the lower end thereof, into the locking slot311and is thus locked by the locking slot. The unlocking assisting member130acts on the inner wall of the support member210to cause the inner wall to be slightly deformed. In this case, where the adjustment assembly300is operated to be displaced downward by a suitable distance, the lower end of each of the support members210is separated from the locking slot311, and is pivoted to a smaller angle under the effect of the unlocking assisting member130such that the lower end of the support member210is slightly flared outward to form an unlocking initial state as illustrated inFIG. 6andFIG. 7.

Apparently, since the lower end of each of the support members210is fitted with the guide surface313under the effect of the unlocking assisting member130, the adjustment assembly300is further operated to be displaced upward, and thus a pivot angle of the support member210is adjusted, such that the support surface of the support member210satisfies a use requirement. Such a structural design plays a proactive role with respect to user operations.

Referring toFIG. 8, the treetop support is adjusted to thus use state in some occasions, such that the treetop support is fixed by the conical support plane formed by the outer surfaces of the support members210. Nevertheless, an angle of conical surface of the conical support plane is not limited to the angle as illustrated inFIG. 8, but may be adjusted by the upward and downward displacements of the adjustment assembly300along the support rod110.

In order that the treetop support achieves a good effect and a beautiful appearance both when being folded and unfolded, a cross section of each of the support members210is in a circular shape with a ¼ circumference, such that the treetop support is formed as a cylinder-like structure as illustrated inFIG. 1andFIG. 2to act as a treetop support capable of receiving or matching a fixing inner cavity in a cylindrical shape, a prismatic shape, or other shapes when not being used.

Nevertheless, the cross section of the support member210may also be in another shape or radian. For example, when a cross section of the support rod110is a square, the cross section of the support member210is a rectangle having a length equal to a length of each edge of the support rod110. In this way, when each of the support members210is pivoted to be attached to the support rod110, an integral structure in a cubic shaped is formed. In addition, the number of support rods210is not limited to four in the drawings, but may be an even greater or smaller number, for example, two, three, five, sixth, or even more.

Further, for better matching with the treetop decorative piece having a conical fixing cavity, in the treetop support, the pivot shaft201of each of the support members210is arranged to be proximal as much as possible to the top end of the support rod110, such that the treetop support, when being unfolded, has a conical or cone-like support plane.

In some other embodiments, a lower end surface of the support member210is a beveled surface, and thus the lower end surface is better fitted with the guide surface313of the adjustment portion310during the adjustment.

In some other embodiments, the support rod110is hollowed out and formed as an inner cavity11. The inner cavity11includes an upper cavity111such that the treetop decorative piece having a line-shape or rod-shape fixing connection portion is fitted into the upper cavity111, and thus the treetop decorative piece600is fixed. In addition, the inner cavity11is preferably arranged to allow the upper and lower ends of the support rod110to pass through, such that a lower cavity112is formed at the lower end of the support rod110. Where the inner cavity11is not arranged to allow the upper and lower ends of the support rod110to pass through, the upper cavity111is not communicated with the lower cavity112.

Referring toFIG. 17, a lower end of the treetop decorative piece600is provided with a rod-shape fixing connection portion601as a fixing portion of the treetop decorative piece600. The treetop decorative piece is fitted into the upper cavity111, and acts on, by a bottom end of the rod-shaped connection portion601, a bottom of the upper cavity111, or the treetop decorative piece600acts on the upper end of the support rod110. In this way, the treetop decorative piece600is fixed.

Meanwhile, an inner wall of the inner cavity11at the lower end of the support rod110is further provided with female threads.

Referring toFIG. 19, in some other embodiments, the treetop support further includes a first rod401, a second rod402, and a connection member500. An upper end of the first rod401is fitted into the lower cavity112at the lower end of the support rod110. A lower end of the first rod401and an upper end of the second rod402are respectively fitted with an upper end and a lower end of the connection member500.

For example, the inner wall of an inner cavity11at the lower end of the support rod110, and the inner walls of the upper and lower ends of the connection member500are all provided with female threads, and the upper and lower ends of the first rod401and the upper end of the second rod402are correspondingly provided with male threads, such that these parts are fitted with each other by the corresponding thread structures. Nevertheless, besides thread engagement, other known fitting fashions are also available, for example, straight-rod interference fitting, which is not limited herein.

By the first rod401, the second rod402, and the connection member500, the treetop support is fixed to the treetop of the Christmas tree.

In addition, with respect to a gourd-like treetop decorative piece, the decorative piece, due to the rod-like fixing connection portion, may be fixed to the treetop of the Christmas tree by the first rod401, the second rod402, and the connection member500. That is, the support rod101, the first rod401, the second rod402, and the connection member500may be fitted with each other by threads, or may be fitted with each other by insertion (during the insertion engagement, two adjacent parts are fitted with each preferably by interference fitting), such that these parts are connected to each other.

Referring toFIG. 18, the first rod401, the connection member500, and the second rod402are successively connected, the gourd-like treetop decorative piece600is sleeved onto the upper end of the first rod401, and the second rod402is fixed to the treetop of the Christmas tree. In this way, the treetop decorative piece is fixed. Nevertheless, the gourd-like treetop decorative piece600as illustrated in the drawings is only exemplary for illustration purposes. Other treetop decorative pieces having a rod-like fixing connection portion may be likewise fixed by the above structure.

Further, althoughFIG. 13toFIG. 18respectively illustrate fitting states when the treetop support is applicable to different treetop decorative pieces, the shape of the treetop decorative piece matching with the treetop support is not limited to that illustrated in the drawings. In practice, treetop decorative pieces having any corresponding fixing connection portions may be fixed by the treetop support.

Referring toFIG. 20, the treetop support according to an embodiment of the present disclosure is bound and fixed to a treetop by a strap404at a strap fixing port403at the lower end of the second rod402, such that the treetop support is fixed to the treetop of the Christmas tree. In addition, in this embodiment, the first rod401and the second rod402are two totally identical structures for ease of manufacturing, and the lower end of the second rod402is provided with the strap fixing port403for fitting of one end of the strap404. Preferably, the strap404may be a strap having a hook and loop tape, wherein two side surfaces of the strap are respectively provided with loop and hook.
