DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description of the three preferred embodiments of the invention is not intended to limit the invention to these preferred embodiments, but rather to enable any person skilled in the art to make and use this invention.
As shown in FIG. 1, the bicycle carrier 1o of the preferred embodiments includes a post 12 and a fastener 14 coupled to the post 12 and adapted to attach the bicycle carrier 10 to a vehicle. The bicycle carrier 10 is preferably designed to attach a bicycle 16 with a seat tube 20 to a vehicle 18. The bicycle carrier 10 may, however, be used to attach a unicycle or any suitable cycle with a seat tube 20 to a vehicle or any suitable temporary storage.
The post 12 of each of the preferred embodiments functions to be temporarily inserted into the seat tube 20 of an inverted bicycle 16. Since conventional seat tubes have a bore that is cylindrically shaped, the post 12 is preferably a rod that is cylindrically shaped. The post 12 may, however, have any suitable shape. In a first variation, the post 12 is preferably made of a rigid material, such as a metal, and is preferably covered by a protective layer 22. The protective layer 22, which functions to reduce damage to the seat tube 20, is preferably made of a rubber material, but may be made of a plastic material or any other suitable material. In a second variation, as shown in FIG. 2, the post 12 includes a flexible portion 24. The flexible portion 24 functions to conform to the seat tube, regardless of the inner diameter of the seat tube 20. The flexible portion 24 is preferably formed with several projections 26 that extend in a radial direction from the central axis of the post 12. The post 12 of the second variation may include a rigid portion.
In the preferred embodiments, as shown in FIG. 1, the bicycle carrier 10 also includes a frame 28. The frame 28 functions to connect and orient the post 12 and the fastener 14. The frame 28 is preferably made of a rigid material, such as metal, but may be made of any suitable material.
In the first preferred embodiment, the frame 28 preferably includes a first arm 30 that attaches to the post 12 and a second arm 32 that attaches to the fastener 14. The fastener 14 of this embodiment functions to attach the bicycle carrier 10 to a hitch 34 of a vehicle 18 and, as such, is preferably sized and shaped to mate with a receiver of a hitch 34. The fastener 14 is preferably integrally formed with the frame 28, but may be separatly formed and fixed to the frame 28 with any suitable method, such as welding. The frame 28 preferably includes a zig-zag shape that allows the fastener 14 to mate with the hitch 34 closer to the bottom of the vehicle 18 and allows the post 12 to be inserted into the seat tube 20 closer to waist height of a typical user. In a first alternative variation, as shown in FIG. 3, the frame 28 also includes a third arm 36. The bicycle carrier 10 of this variation of the first embodiment also includes an additional receiver 38 for a hitch that allows a user to selectively attach an additional trailer or hitch 34 for additional hauling. In a second alternative variation, as shown in FIG. 4A, the frame 28 also includes a hinge mechanism 40. The hinge mechanism 40 functions to allow a user to pivot the bicycle carrier (and the bicycle) out of the way, and to access a portion of the vehicle (such as a luggage compartment). The hinge mechanism 40 operates between a locked position and an unlocked position, shown in FIG. 4B. In a third alternative variation, as shown in FIG. 5, the frame 28 defines a bore 42. The bore 42 is sized to accept a section of the post 12. The bicycle carrier 10 of this variation also includes a securing mechanism 44 that attaches to the end of the post 12 thereby securing the post 12 to the frame 28. The securing mechanism 44 is preferably a threaded nut, but may alternatively be any suitable device able to secure the post 12 to the frame 28. With this third alternative variation of the first preferred embodiment, the bicycle carrier 10 is able to be displayed and shipped to the user in a compact package and the user is able to assemble the bicycle carrier 10 with standard tools found in the typical home.
In the second preferred embodiment, as shown in FIG. 6, the frame 28 preferably extends the substantial width of a bed 46 of the vehicle 18, such as a truck. The fastener 14 of this embodiment functions to attach the bicycle carrier 10 to the bed 46 of the vehicle 18. The fastener 14 preferably includes bolts, but may include any suitable device or method, including magnets, that attach the bicycle carrier 10 to the bed 46 of the vehicle 18.
In the third preferred embodiment, as shown in FIG. 7, the frame 28 preferably extends the substantial width of a roof 48 of the vehicle 18, such as a sedan or a wagon. The fastener 14 of this embodiment functions to attach the bicycle carrier 10 to the roof 48 of the vehicle 18. The fastener 14 preferably includes clamps that attach to the rain gutters or roof racks of the vehicle 18, but may include any suitable device or method that attach the bicycle carrier 10 to the roof 48 of the vehicle 18.
In each of the preferred embodiments, but as best shown in FIG. 1, the bicycle carrier 10 also includes a guide 50 coupled to the frame 28. The guide 50 functions to substantially prevent rotation of the bicycle 16 about the post 12 during the transportation of the bicycle 16. The guide 50 preferably includes a pair of rods 52 and 54. Both rods 52 and 54 include a first end that is connected to the frame 28 and a second end that cooperatively creates a fork 56. The fork 56 functions to receive the top tube, or any other suitable portion, of the bicycle 16. Preferably, the rods 52 and 54 are made of a material that allows them to be flexed into different orientations to receive top tubes, or other suitable portions, of bicycles with different sizes and/or proportions. In a first alternative variation, the rods 52 and 54 may be integrally formed to each other, effectively becoming one rod. In other alternative embodiments, the bicycle carrier 1o may include any suitable device to substantially prevent rotation of the bicycle 16.
In each of the preferred embodiment, the bicycle carrier 10 also includes a hold-down system 58 coupled to the frame 28. The hold-down system 58 functions to substantially prevent lift of the bicycle 16 off the post 12 during the transportation of the bicycle 16. The hold-down system 58 preferably includes a flexible cable 60 that wraps around the top tube, or any other suitable portion, of the bicycle 16 and a cable cleat 62 that engages and holds the strap. The hold-down system 58 may alternatively include belts, ties, clamps, or any other suitable device or method that substantially prevents lift of the bicycle 16 off the post 12.
In each of the preferred embodiment, the bicycle carrier 10 also includes a handlebar stabilizing system 64. The handlebar stabilizing system 64 functions to prevent rotation of a handlebar of the bicycle 16 during the transportation of the bicycle 16. The handlebar stabilizing system 64 preferably includes an elastic cable 66 that wraps around the handlebar, or any other suitable portion of the bicycle 16, and a cable ball 68 that allows the elastic cable 66 to engage itself. The handlebar stabilizing system 64 may alternatively include belts, ties, clamps, or any other suitable device or method that substantially prevents rotation of a handlebar of the bicycle 16.
In the first preferred embodiments, the bicycle carrier 10 also includes a locking loop 70. The locking loop 70 functions to receive a lock, such as a chain or bar lock. The lock may be inserted through the top tube, or any other suitable portion of the bicycle 16, and the locking loop 70 to secure the bicycle 16 to the bicycle carrier 10, and hence to the vehicle 18. The locking loop 70 is preferably made of a metal material, but may alternatively be made of any suitable material.
In each of the preferred embodiments, as best shown in FIG. 1, the bicycle carrier 10 includes a second post 72. Preferably, the guide 50, hold-down system 58, and handlebar stabilizing system 64 are provided for each post 12. Preferably, the respective guide 50, hold-down system 58, and handlebar stabilizing system 64 are attached to the frame 28 on alternate sides to prevent interference. It will be understood by those in the art that, if appropriate structural adjustments are made to the frame 28 and the fastener 14, there may be more or less than two posts included in the bicycle carrier 10.
As shown in FIGS. 8A, 8B, and 8C, the method of the preferred embodiment includes the following steps: providing a bicycle carrier 1o having a post 12 and a fastener 14 and attaching the fastener 14 of the bicycle carrier 10 to the vehicle, removing a seat post 74 of the bicycle 16 and inverting the bicycle 16, and inserting the post 12 into the seat tube 20 of the bicycle 16. The method may also include other suitable steps, such as substantially preventing rotation of the bicycle 16 about the post 12, substantially preventing lift of the bicycle 16 off the post 12, and substantially preventing rotation of a handlebar of the bicycle 16.
The actual size and shape of a finished product of one of the preferred embodiments will depend, in part, on aesthetic considerations.
