BACKGROUND
The present invention relates to a container and case for the storage and transport of a bicycle. More particularly, the invention relates to a container for storage and transport of a bicycle in partial disassembly.
In recent years, the popularization of lightweight bicycles has greatly increased sport and competitive usage of such machines, particularly bicycles especially designed with extremely lightweight frames and other components and intended for long distance riding. Such machines are constructed of lightweight metals or carbon fiber and are precision machined and balanced to provide maximum speed and range with minimum weight. Such machines are commonly provided with derailleur multi-speed mechanisms.
Unfortunately, as the weight of modem bicycles is reduced, and the precision machining features are increased, the bicycle mechanism becomes more fragile and susceptible to damage from abusive handling. Lightweight wheels and rims are susceptible to bending, and derailleur mechanisms are susceptible to misalignment.
Bicycle touring has also become popularized in recent years. One aspect of this sport involves the long distance touring of groups of bicyclists in places remote from their homes. Typically, the bicyclist transports himself and his machine to a remote starting point by auto, train, bus or airplane and engages in the sport of touring in regions remote from the bicyclist's home location. At the completion of such touring events the bicyclist and his machine are transported back to their home location.
In the normal and other usage of a modem lightweight bicycle great care must be taken for the storage and transport of the machine to avoid damage or destruction to the machine. Since machines of such precision have become extremely expensive and difficult to repair, a need has arisen for a container device which can safely store and transport a bicycle, even under the abusive handling conditions typically found in commercial airline service. Such a container must be more than a mere box for enclosing the bicycle, for it must be as compact as possible to conserve space during shipping, and it must protect the components of the bicycle from wear and damage caused when the frame of the bicycle contacts other bicycle components, such as the wheels of the bicyle, during transport.
Various configurations of bicycle cases have been developed. However, one problem that has not been satisfactorily addressed is the storage of the wheels for the bicycle. As can be imagined, the bicycle case should be designed to be as compact as possible while providing enough interior room to pack the bicycle safely and securely. Typically, the wheels of the bicycle are removed for shipment. Various configurations have been used to position the wheels alongside the bicycle to minimize the profile of the bicycle within the box or carrier. However, the rims and spokes of the bicycle often are left in contact with the frame or components of the bicycle, which may damage the bicycle or the wheels if the wheels shift during transport.
What has been needed and heretofore unavailable is a compact, light yet robust, carrier box and wheel transportation system providing for safe and easy shipment of a bicycle, while incorporating features, particularly with respect to storing the wheels, that prevent damage to the frame, wheels and other components of the bicycle during transport of the bicycle. The present invention satisfies these and other needs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings in detail, in which like reference numerals indicate like or corresponding elements among the several figures, there is shown in FIGS. 1-3 a series of views of a one embodiment of a bicycle transport case 10 in accordance with the principles of the present invention. The case includes a base 15, a first side 30 and a second side 35 that removably attaches to the base using fasteners 40, 45, 50 of a type well known in the art.
As shown in the FIGS. 1-3, a pair of rear wheels 20 may be disposed at a bottom rear of the base 15 to facilitate movement of the base across a surface. In some embodiments, a pair of front wheels 25 may be disposed at a front end of base 15, resulting in the placement of wheels at all four corners of the base, as shown in the figures, so that the base may be freely rolled from one location to another. Those skilled in the art, however, will recognize that rollers may be substituted for the wheels, and that the case can be moved even if it only includes a single pair of wheels or a roller or rollers disposed at one end of the case, allowing the non-wheeled end to be tilted up and the case rolled on the wheeled end.
A handle or strap 60 may be mounted on one side of the case to assist in pulling the case over a surface. In an embodiment having only a pair or wheels mounted at one end of the base, the strap or handle would typically be mounted on the opposite end of the case relative to the wheels. One or more handles or straps 55 may also be mounted on a top surface of the case 10 to facilitate lifting of the case. In the embodiments shown, the handles or straps 55, 60 are shown mounted on the second side 35 of the case. Alternatively, they may be mounted on the first 30, or mounted on a combination of first and second sides. Of course, additional handles or straps may be mounted on the sides or side panels of the case without departing from the intended scope of the invention.
FIG. 2 illustrates how the exemplary embodiment includes both a first side 30 and second side 35 which releasably couple using couplers 45, 50 to each other to form a cavity that is configured to enclose a bicycle mounted to the base 15. Typically, as will be discussed in more detail below, the wheels of the bicycle are removed from the frame of the bicycle prior to mounting the bicycle within the case 10. Each of the first side 30 and second side 35 also include couplers to couple the respective sides to the base 15.
Each of the first and second sides 30, 35 has a height dimension, a length dimension and a width dimension, with the length dimension being approximately the same as a length dimension of the base. The sum of the width dimensions of the first and second sides approximates the width of the base, and the height dimension of the first and second sides are generally the same, and sufficient to enclose the height of a bicycle that is mounted to the base. Note, however, that the width dimensions of the first and second side may not be equal, and in some embodiments, will not be equal, as is shown in FIGS. 1-3.
Referring now to FIG. 4, details of the base 15 of the transport case are shown. The base 15 of the transport case includes various fixtures and assemblies configured to securely hold a bicycle frame, and in some embodiments, additional accessories, tools or other items securely within the case during shipment. As shown, the base includes a bottom 105, and low sides (See FIG. 1) that surround the circumference of the base to define a shallow cavity having bottom 105 at one end, and open above to allow placement of a bicycle onto the fixtures attached to bottom 105 of base 15. It will be understood, however, that the low sides are not necessary to the invention. All that is needed is that the base be configured to allow the first and second sides to mate with the base to form a cavity in which a bicycle may be mounted. The base also includes appropriate fixtures or fasteners 110 that cooperate with fixtures or fasteners 40 mounted to the first and second sides to secure the first and second sides to the base.
Base 15 is configured to allow attachment of various fixtures and assemblies configured to secure the bicycle to the base. In one embodiment, one or more slots 95 may be machined into a top surface of the bottom 105 of base in such as manner as to form a groove or grooves shaped to receive a pin having a head configured to be retained within the groove. An opening may be formed at one end of the groove to allow the pin to be inserted into the groove. In another embodiment, a pair of L-shaped or U-shaped rails (not shown) may be mounted to the base, the pair of rails cooperating such that a pin having shaft sized smaller than the width of the groove, and also having a head sized larger than the groove, but smaller than the separation between the interior of the rails, can be placed within the assembly, yet retained by the assembly.
In another embodiment, a second plate may be mounted over the bottom 105 of the base in such a manner that grooves may be formed in the second plate to accept the mounting pins of various fixtures, as will be described below.
In still another embodiment, various hooks, loops or other fasteners 100 may be affixed to the base to facilitate tying down various accessories, tools or other items, such as handle bars, seat/post, helmet, shoes, aero bars, pump, track sack, pedals, shoes or tools.
As shown, a rear dropout receiving assembly 90, also called a rear mounting assembly or rear dropout mount, as will be described in more detail with reference to FIGS. 7A-7C, may also be mounted on bottom 105 of base 15. The rear mounting assembly may be fixed in place, as shown, or may also be configured to engage one or more grooves or rails as discussed above to maintain the rear mounting assembly in place, yet allowing the rear mounting assembly to be moved forward and rearward to assist in accommodating different sized bicycles.
FIG. 5A is a side view of case 10 looking into the interior portion of the second side 35 when second side 35 is mounted to the base 15. As shown in FIGS. 1-3, second side 35 has a pair of raised side lips 155 and a top lip 160 that are joined to back panel 150 of the second side to define a cavity for accommodating a pair of bicycle wheels. In one embodiment, a tap 165 is mounted to the top edge, the tab having an opening 170 formed therein. In other embodiments, tab 165 may be a fastener or catch. Also mounted to the side lips are one or more fasteners 175, which may be one side of a hook and loop fastener, or may be one side of a magnet and plate fastener.
A pair of wheel mounts 180, 185 are mounted to back panel 150 and configured to receive at least a portion of an axle assembly of a bicycle wheel in such a manner so as to maintain the wheel in position relative to the wheel mount 180, 185 when the wheel is so mounted. Wheel mounts 180, 185 may be formed so as to hold and lock the axle in place, or they may be configured to be used with a quick release system, wherein the mount receives one end of bicycle quick release skewer, which when hand tightened by activating the cam of the skewer of the quick release, tightens the wheel against the wheel mount to releasably hold the wheel in place.
FIG. 5B is a side view of a protective panel 200 that is sized to fit within the area bounded by the inner walls of raised side lips 155 and top lip 160 and the top of the base. Protective panel 200 is typically fairly stiff, and may be coated on one or more sides with a protective material. A layer of compressible foam may also be attached to one or both sides of panel 200. In use, panel 200 is placed over the wheels once the wheels are mounted in wheel mounts 180, 185. In this manner, panel 200 isolates the wheels from the rest of the bicycle that is mounted to the base 15 of the transport case 10. The wheel side of panel 200 may also include one or more fasteners, such as the opposite side of hook and loop fastener system, or magnet and plate system. For example, where fastener 175 is a hook portion of a hook and loop system, the loop portion of the fastener system would be mounted on the wheel side of panel 200 so that when panel 200 is positioned over the wheels mounted to second side 35, the loop portion engages the hook portion to hold panel 200 in place. Of course, it does not matter whether the hook portion or the loop portion is mounted to the second side or the panel 200, as long as each portion engages the other to hold panel 200 in place. Those skilled in the art will understand that a hook and loop fastener system, or magnet and plate system have been described for example only, and that releasable fastener systems may be used without departing from the intended scope of the invention.
In one embodiment, panel 200 includes an opening 205 that allows for use of a finger or other instrument to be inserted to facilitate removal of panel 200 from its mounted position to expose the wheels of the bicycle. Opening 205 may also be used accommodate a releasable latching system, the hole being used to mount a locking mechanism such as a camlock that then cooperates with opening 170 (or an assembly disposed within hole 170) of tab 160 (FIG. 5A) to securely hold panel 200 in place.
In another embodiment, the second side may also include slots, brackets or other features such as rotatable tabs or latches to allow attachment of a panel to be removably mounted to the second side overlaying the attached wheels. In this manner the panel encloses the wheels within the cavity formed by the second side and its two side panels and top panel, and provides for separation of the wheels from the frame of the bicycle during shipment. The panel may be any suitable material, such as plastic, wood or wood product, metal or foam. In an alternative embodiment, the sides of the panel may include various hooks, loops or other fasteners to facilitate tying down various accessories, tools or other items.
FIGS. 6A and 6B illustrate embodiments of a front fork mount 200 that may be mounted to the base 15 to secure the front fork of a bicycle being shipped in the transport case 10. A quick release axle spindle (FIGS. 8C-D) is received in an appropriately sized bore 205 of the front fork mount 200. In the embodiment shown, the mount includes a bottom portion 201 and a removable top portion 215 that holds the quick release axle spindle in place in bore 205. In this embodiment, the quick release axle spindle is held within bore 205 in a fixed position by pressure on the spindle when top portion 215 is fastened onto bottom portion 210 using fasteners 220.
In an alternative embodiment, top portion 215 and bottom portion 210 may be a single piece, with bore 205 sized slightly larger than the diameter of the quick release axle spindle so that the spindle may be inserted through the bore 205. The spindle is held within bore 205 when a wheel is mounted on the spindle and a quick release skewer is threaded through the spindle and tightened.
A tab 225 configured to cooperate with the one or more grooves 95 in the base 15 is disposed at a bottom end 230 of bottom portion 210. Tab 225 is inserted into a groove in the base 15 to provide adjustment of the position of the fork mount along the lengthwise dimension of the base 15 to accommodate different sizes of bicycles. Tab 225 may be mushroom shaped, as shown in FIG. 6A, or it may take on other shapes, such as the T-shaped tab 235 shown in FIG. 6B. For example, the mushroom shaped tab 225 of FIG. 6A or the T-shaped tab 235 of FIG. 6B may be used where a single groove is formed in the base 15. Where a pair of rails are mounted on base 15 to provide for lengthwise adjustment of the position of front fork mount 200, the T-shaped tab 235 may be used. Both the mushroom shape and the T-shape may be characterized generally in that the shapes have a pin 227, 228 to which is mounted a head 228, 238 respectively.
In some embodiments, the bottom end 230 may include a portion 240 that is angled relative to the remainder of bottom end 230. This angulation provides a locking capability to hold the front fork mount in place on base 15 when the mount is in position to receive the front fork of a bicycle. This angulation allows the mount to lean backwards slightly, tilting the pin and head and locking the head against the top surface of the groove or rail. The position of the front fork mount may be adjusted by simply leaning the front fork mount 200 in an appropriate direction to “unlock” the front fork mount, and then sliding the front fork mount along the groove or rails to reposition the front fork mount.
FIGS. 7A-D illustrate embodiments of a rear drop out mount 300 that is similar to the front fork mount, but may be sized differently to ensure adequate clearance of various bicycle components above the base 15 of the transport case 10 when the bicycle is mounted to the base to prevent damage to those components.
FIG. 7A is a perspective view of one embodiment of the rear drop out mount 300 showing a bottom portion 305 and a top portion 310 that is fastened to the bottom portion 305 using fasteners 320, such as threaded screws or bolts, inserted through bores formed into top portion 310 and threaded into threaded holes formed in bottom portion 305. This arrangement allows top portion 310 to place pressure on a spindle that that is inserted through bore 315 (FIGS. 7B-D) to hold the spindle in place.
In an alternative embodiment, as described with reference to the front fork mount 200 above, rear drop out mount may be formed in a single piece, with bore 315 sized to be slight larger than the diameter of a spindle, allowing the spindle to be inserted into and extend through bore 315 in a loosely fitting manner. A quick release skewer 325 (FIG. 7A) may be inserted through the spindle to hold the spindle in place when lever 330 of the quick release spindle is actuated to tighten the quick release skewer.
Also shown in FIG. 7A is a faux cog 335 which may be mounted on the spindle, either fixedly, or rotatably and removably. Faux cog 335 provides for mounting of the chain of the bicycle being transported in such a manner as to put tension on the chain so that the chain does not move during transport, which would otherwise possible cause damage to the bicycle frame or other components.
In some embodiments, the quick release skewer 330 may include a round wheel- or gear-chain holder 335 for holding the chain of the bicycle to prevent movement of the chain during shipment of the transport case. This prevents the chain from marring the paint of the bicycle, or otherwise damaging the bicycle. A similar quick release mechanism is utilized to hold the front fork of the bicycle. However, as is well known in the art, a chain holder is not needed at the front fork mount.
The rear drop out mount 300 may be fixed to the base 15, or rear drop out mount 300 may include a tab 340 such as that previously described with reference to the front fork mount 200. This tab can be received into the groove of the base to allow adjustment of the position of the rear drop out mount along the lengthwise dimension of the base to accommodate different sizes of bicycles. A bottom end 345 of the rear drop out mount 300 may have an angled portion 350 to provide a “locking” capability to hold the rear drop out mount 300 in position on the base 15, in those embodiments where rear drop out mount 300 is not fixed to base 15, but is instead moveable. This angulation allows the mount to lean backwards slightly, tilting the pin and head of the tab and locking the head of the tab against the top surface of the groove or rail.
While the figures illustrate both front fork and rear drop out mounts as both having tabs, and thus both being adjustable, those skilled in the art will appreciate that only one of the mounts can be adjustable, with the other mount fixed, and still provide the amount of adjustment necessary to accommodate different sized bicycles. Similarly, in embodiments where only one of the mounts is moveable, the length of the groove or slot in the base that receives the tab of the moveable mount need only be as long as necessary to provide the amount of movement needed to accommodate a typical range of bicycle sizes. Also, while a mushroom-shaped tab is disclosed and shown in FIGS. 6 and 7, other shapes are possible, so long as they provide for retention of the tab within the groove or slot when the mount is moved.
FIG. 8 illustrates various embodiments of quick release mechanisms that are may be used in concert with the mounts of FIGS. 7A-D to hold the rear drop outs of the bicycle to the base 15 of the transport case 10. FIG. 8A is a side view of a quick release spindle 400 showing a chain holder 405 mounted to one end of a faux axle 410 having a bore 415 through which a hand actuated skewer commonly known in the art extends.
FIG. 8B shows an embodiment of a spindle 430 having a hollow faux axle 435 that is designed for use with a track bicycle. Its length is generally shorter than a spindle 450 that is used for mounting a road bicycle, as shown in FIGS. 8C and 8D, due to the increased length needed to accommodate the wider separation between chain stays commonly found on a bicycle having a rear cassette and derailleur system for changing gears, unlike a track or fixed gear bicycle which typically has only one cog and lacks a derailleur.
Referring again to FIG. 5A, there is shown an embodiment of wheel mounting brackets 180, 185 mounted to the inside of the second side 35 of the transport case 10. These brackets are configured to accept a fixture 500 attached to an axle or quick release of a wheel, as is shown in FIG. 9. The fixture of FIG. 9 includes a central portion 505 that projects above a main body 510 of the fixture. Central portion 505 includes a bore 515 that extends through the fixture. The main body 510 is sized and configured to engage the wheel mounts 180, 185 mounted to the second side 35 of the transport case 10 in such a manner as to hold a bicycle wheel in place in the transport case 10.
In some embodiments, the bore 515 of central portion 505 may be threaded and configured to thread onto a wheel axle. Alternatively, the bore may be threaded to accept the threaded end of a quick release skewer inserted through a hollow axle of a bicycle wheel, (hollow axles are common on most bicycles, as they allow a quick-release skewer to be used to removably attach the wheel to the drop outs of the fork and frame). Once the fixture 500 is threaded onto the wheel axle or quick release of the wheel, the main body 510 of the fixture is inserted into a slot 182, 187 of the wheel mounting bracket 180, 185 respectively (FIG. 5A), and is maintained within the wheel mounting bracket through the cooperation of the main body and wheel mounting bracket to retain the wheel in the bracket. The slot of the wheel mounting bracket (FIG. 5A) may also be configured so that as the projecting central portion 505 of the fixture 500 is slid into the slot 182, 187, the shape of the slot cooperates with the shape of the projecting central portion of the fixture to lock the fixture in place in the wheel mounting bracket.
In one embodiment, two adjacent comers 520, 535 along one side of main body 510 may be rounded, or otherwise configured, to improve the ease of insertion of fixture 500 into wheel mounting brackets 180, 185. Alternatively, main body 510 may have a rounded shape.
FIG. 10 is an illustration of another embodiment of the invention, showing a base portion 600 having a front dropout retainer 610 and a rear drop out retainer 615 mounted to a bottom 620 of the base. As in other embodiments discussed above, base portion 600 may include wheels 605 disposed at one or more portions of the base, such as at one bottom edge of the base, or at two or more corners of the base.
The front and rear dropout retainers 610, 615 may be mounted to the floor 620 of the base portion 605. However, the front dropout retainer 610 may also be moveably mounted to the floor 620 as described above.
In most cases, rear dropout retainer 615 will be fixed to the floor 620. However, like the front dropout retainer, it may be moveably mounted to the floor as described above so as to provide for addition adjustment to accommodate various sizes of bicycle frames.
FIGS. 11 and 12 illustrate details of the rear dropout retainer of this embodiment. As shown, the rear dropout retainer includes a mounting fixture 625 that is affixed to the floor 620 of the base 600. The rear dropout retainer also includes a telescoping assembly formed from a bottom portion 630 and a top portion 635. As shown, the bottom and top portions are tubular in construction. In one embodiment, an outer diameter of top portion 635 is less than an inner diameter of bottom portion 630, and thus may slide into bottom portion in such a way that the length of the telescoping assembly can be lengthened or shortened according to the size of bicycle frame being placed into the transport case.
As shown in FIG. 12, the top portion 635 includes a slot 670 that extends into the interior of the tube that forms top portion 635. Bottom portion may include an opening extending through the wall of the tube forming the bottom portion. A fastener 655, such as a screw or bolt or the like may be inserted through the opening in the bottom portion and into slot 670, thus joining the top portion to the bottom portion. Those skilled in the art will understand that this arrangement allows the top portion to telescope within the bottom portion thus allowing the overall length of the telescoping assembly to be altered as needed.
It will also be understood by those skilled in the art that slot 670 may replicated on the opposite side of the top portion, and also that an opening may also be formed in the opposite side of the bottom portion so that fastener 655 may extend through the bottom and top portions to facilitate tightening and loosening fastener 655. In some embodiments, fastener 655 may be a nut 657 and bolt combination, with the nut removable from the bolt. In another embodiment, the nut may be permanently mounted on the bottom portion by welding, adhesive, or other means known in the art. In a further embodiment, the walls of the tube of the bottom portion defining the opening may also include threads configured to engage the threads of the bolt or screw, thus eliminating the need for a nut.
While the telescoping assembly has been described wherein the top portion 635 is inserted into the bottom portion 630, the function provided by this arrangement may be provided in other ways. For example, the top and bottom portions may be formed so that the bottom portion may be inserted into the top portion. Alternatively, rather than be tubular in shape, the top and bottom portions may be square in shape, and still telescope. In still another embodiment, any shape may be used provided the top portion engages the bottom portion in a manner that provides for one or both to moveably engage the other so that the overall length of the assembly may be altered to accommodate different sizes of bicycles frames being mounted within the transport case.
Returning now to FIGS. 11 and 12, an opening may be disposed in a bottom portion of the bottom portion 630, the opening extending through the bottom portion 630. This opening is configured to receive a fastener 660 extending through the mount 625 into and through the bottom portion 635. Fastener 660 may be tightened with a nut 662. As can be seen, mounting the bottom portion 630 to rotate around fastener 660 aids in adjusting the longitudinal position of the rear dropout retainer to accommodate different sized bicycle frames.
Rear dropout retainer 615 also includes a tube 640 that is sized to fit between the rear dropouts of a bicycle. Plugs 645, 650 each have an opening configured to accept a skewer, may be inserted into the ends of tube 640. These plugs may be formed of metal, plastic or any other suitable material. The plugs may also be provided in a set having pairs of plugs, with the individual plugs of the pair having a selected size, different from another pair of the set of plugs. In this way, bicycles of differing type, or having a different distance between the rear dropouts of the bicycle, may be accommodated by the embodiments of the rear drop retainer of the present invention. In another embodiment, the plugs and ends of the tube 640 may be threaded. In this embodiment, the plugs may be turned within the end of the tube so as to lengthen or shorten the length of tube 640 to accommodate the space between the rear dropout of a bicycle.
The rear dropout retainer 615 is advantageous because the retainer may be pivoted forward and back and the length and width of the retainer may be adjusted to accommodate various types of bicycles. In this embodiment, this adjustment can be made without having to relocate the mount of the rear dropout retainer along the length of the floor of the base.
The bicycle transport case may be formed from metal, wood, plastic, or any combination of these. For example, the outer sides and surfaces of the case may be formed of plastic, and the base may have a metal insert forming a foundation for the groove and mounts to be mounted thereon. Alternatively, the base may be formed entirely of metal. Where a suitable plastic is used for the base, the grooves may be formed in the plastic and used for mounting the fork and rear drop out mounts, while reducing the overall weight of the transport case.
While the bicycle transport case has been described as having the wheel mounts for the bicycle's wheels mounted on one of the sides (specifically, the second side) of the case, other embodiments are possible where the width dimension of both the first and second sides is sufficient to allow a wheel, or more than one wheel, to be mounted on each side. In those embodiments, a protective panel could be included for each side to isolate the wheel or wheels mounted on each side to be isolated from a bicycle mounted on the base between the two sides. In other embodiments, the base is wide enough to accommodate at least two bicycle frames, and wheel mounts are provided on each of the first and second sides for mounting the wheels of both bicycles.
While several particular forms of the invention have been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention.
