DETAILED DESCRIPTION
The present Bicycle Transporting Systems will now be discussed in detail with regard to the attached drawing figures, which were briefly described above. In the following description, numerous specific details are set forth illustrating the Applicant's best mode for practicing the Bicycle Transporting Systems and enabling one of ordinary skill in the art to make and use the Bicycle Transporting Systems. It will be obvious, however, to one skilled in the art that the present Bicycle Transporting Systems may be practiced without many of these specific details. In other instances, well-known manufacturing methods, mechanical engineering considerations, and other details have not been described in particular detail in order to avoid unnecessarily obscuring this disclosure.
FIG. 1 shows a perspective view illustrating bicycle transporting system 100 that includes a T-shaped rack 102 to transport bicycle 104 by hanging and bracing bicycle 104 by wheels 106 while rack 102 may be mounted to receiver hitch 108 of vehicle 110. Rack 102 holds wheels 106 of bicycle 104 by passing hooks 112 through wheels 106 and allowing wheels 106 to rest and suspend from hooks 112, as shown. Rack 102 braces wheels 106 by holding wheels 106 along braces 114, as shown. Braces 114 extend alongside the portions of wheels 106 while wheels 106 are suspended by hooks 112, as shown. Braces 114 minimize rotation of stem and headset 117. Said another way, braces 114 hold the front wheel and rear wheel of bicycle 104 in relatively similar planes thereby preventing shifting of the load of bicycle 104, such as, for example, shifting caused by transporting. This embodiment is shown with positions for two bicycles, the first bicycle is drawn in FIG. 1, a second bicycle could be positioned on the hooks between vehicle 110 and bicycle 104.
Rack 102 has groove 116 to hold wheels 106, as shown. Groove 116 holds wheels 106 to prevent rotation around the axis formed by the suspension of the front wheel on the front hook and the rear wheel on the rear hook. Groove 116 limits swaying of the bicycle around this axis. Together, hooks 112, braces 114, and groove 116 allow placement of bicycle 104 onto rack 102 with a single lift and placement of bicycle on rack 102, as shown. After lifting and placing, bicycle 102 may be unlikely to shift during transport. Further, wheels 106 may be secured with strap 120, as shown, which may prevent wheels 106 from becoming dislodged from hooks 112 during transport by vehicle 110.
Rack 102 removeably attaches to vehicle 110. Rack 102 includes a mount 118 that couples with receiving hitch 108, as shown. Mount 118 may be formed to mate with receiving hitch 108, for example, mount 118 may include an aperture that permits a bolt to extend from one side of the receiving hitch 108, through mount 118, and out the other side of receiving hitch 108, where the bolt may be held in place by a cotter pin or other fastener. Receiving hitch 108 may support a maximum tongue weight of maximum force that may be exerted on receiving hitch 108. Rack 102 may be designed considering the average maximum tongue weight or the tongue weight for a particular vehicle or a particular class of vehicles, for example, materials selected for use in rack 102 may be selected to minimize the weight exerted on receiving hitch 108 while providing sufficient stiffness while fully loaded with various size bicycles.
Rack 102 may be a single, integral frame, for example, rack 102 may be built from commercially available square steel tubing, cut to fit the design, and then permanently welded together. In another embodiment, the rack may include a single, integral frame (including the mount, the t-shaped frame, the braces, the sway-limiting groove, and/or other desirable portions) which may be manufactured as a single piece (for example by extrusion, molding or other techniques). In further embodiments, the rack may include a hinge, joint, or other means to allow folding or separation of the rack along two or more portions to allow for storage. These racks provide for transporting bicycles on a vehicle, when the bicycle has a front and rear wheel attached to a bicycle frame, when the wheels have spokes (or other passage between the tire and the axle) and a headset (or other hinge to allow steering between the wheels). These racks have hooks or other suspenders to suspend the front wheel and the rear wheel by passing through the wheel (between the tire and the axle) so that the wheel suspends from the hook or suspenders while the wheels are attached to the bicycle frame in an operable position. The hooks or suspenders may be attached to a support separated by a span sufficient to allow suspension of the bicycle while the front wheel or rear wheel remain operably attached to the bicycle. The support may be attached to a mount to mount the support to a vehicle. System 100 may further include a sway limiter to limit the sway of the bicycle around the axis formed between the front and rear wheel hooks. Other embodiments disclosed herein may show other types and configurations of hooks, suspenders, fasteners, mounts and other parts of the system.
FIG. 2 shows a perspective view illustrating bicycle transporting system 200 including rack 202 to transport bicycle 206 by hanging and bracing bicycle 204 by wheels 208 and mounting to bumper 206 of the vehicle (without a receiver hitch), where rack 202 may be folded while not in use and adjusted for bicycles of differing wheel spans and different size wheels. In this embodiment, rack 202 may connect to the vehicle by attachment to bumper 206, as shown. Rack 202 may terminate in a bumper-mating plate 207, which may be designed to conform or mate to the shape or profile of the bumper, such as, for example, an L-shaped plate to cover the top and face of the bumper. Bumper-mating plate 207 may extend along the length of bumper 206, along either side of rack 202, as shown. Bumper-mating plate 207 may extend along bumper 206 far enough to support rack 202 when rack 202 may be holding the maximum number of bicycles. Bumper-mating plate 207 may be lined with liner 210, such as, for example a rubber coating, a foam cushion, or other material that may prevent damaging bumper 206 or the paint on bumper 206. Bumper-mating plate 207 may be removeably attached to bumper 206 using two or more straps 212, as shown. Alternately, fasteners other than straps may be used, such as, for example, hooks, screws, or clips, hook and loop fasteners, etc.,
Bottom frame 214 and upright frame 216 may be hingedly connected, as shown. Bottom frame 214 may include hinge 218, as shown, which allows hinge 218 to rotate to allow bottom frame 214 to fold toward upright frame 216. When hinge 218 is in the fully open position, bolt 220 may be placed through a set of apertures in bottom frame 214 and a set of apertures in upright frame 216, thereby preventing movement of hinge 218 when rack 202 is in use. This arrangement may allow for folding of rack 202 during storage, but, still allows the rack to be substantially immobile during transportation of bikes. Mount 222 may be used to add additional frames to carry additional bikes. (See FIG. 4 and FIG. 12 for discussion of hitching additional frames.)
Rack 202 may adjust for bikes of different size wheel spans or different size wheels. In this embodiment, rack 202 includes a T-shape, with one arm of the T an adjustable arm 224 that includes a series of apertures 226, as shown. Slideable member 228 includes aperture 230, which is sized to permit sliding along the adjustable arm 224, as shown. To move slideable member 228, bolt 232 may be removed from slideable member 228, which will allow slideable member 228 to slide along adjustable arm 224, as shown. After moving slideable member 228, slideable member may be aligned with the series of apertures 226, which will allow bolt 232 to be reinserted, thereby preventing any further movement of slideable member 228. Slideable member 228 may be positioned to allow hooks 234 to suspend wheels 208 from the topmost portion of each wheel, when both wheels 208 are suspended from hooks 234. Bolt 232 may be further secured by a cotter pin on the underside. This arrangement may allow adjustment for wheel span without requiring any balance, lifting or other dexterous action by the user. After adjustment, placement of bolt 234 may be performed without holding slideable member 228 in position.
Bicycle 204 may be positioned on rack 202 for transporting, as shown. Bicycle 204 may be lifted high enough so that wheels 208 may pass over hooks 234 as shown. Wheels 208 may rest on protective covering 236, as shown. Protective covering 236 may cover hooks 234 to help protect the paint, finish or other surface of wheels 208, as shown. Wheels 208 may rest along braces 238, as shown. Again (similar to the previous embodiment), braces 238 may prevent rotation of the stem and headset of bicycle 204, as shown. Bungee cord 240 may wrap from fastener mount 212, to underneath a portion of hook 234, to secure on the other side of fastener mount 212, as shown. Bungee cord 240 may assist holding wheels 208 onto hooks 234 and along braces 238, even while the vehicle is in motion.
Bicycle 204 may be prevented from swaying along the axis formed by hooks 234, as shown. Rack 202 may include sway-limiting member 242, as shown. Sway-limiting member 242 may be connected to upright member 216 by hinge 244, as shown. Hinge 242 may allow sway-limiting member 242 to adjust to the size of wheels 208 of bicycle 204, as shown. For larger wheels, hinge 244 may allow sway-limiting member 242 to move toward upright member 216 to accommodate larger wheels. For smaller wheels, hinge 244 may allow sway-limiting member to move away from upright member 216 to accommodate smaller wheels. Sway-limiting member 242 allows a portion of wheels 208 to rest in a groove at distal end of sway-limiting member. When wheels 208 are positioned within sway-limiting member 242, sway-limiting member 242 will prevent swaying of the bicycle during transportation, including when the vehicle accelerates and decelerates.
System 200 provides for transporting a bicycle on a vehicle, when the bicycle has two wheels, (a front and a rear wheel), that are operably connected to the bicycle frame separated by a headset (or other hinge) to allow steering between the wheels. The system includes a rack, such rack has hooks or other suspenders to suspend the front wheel and the rear wheel by passing through the wheel (between the tire and the axle) so that the wheel suspends from the hook or suspenders while the wheels are attached to the bicycle frame in an operable position. The hooks or suspenders may be attached to a support separated by a span sufficient to allow suspension of the bicycle while the front wheel or rear wheel remain operably attached to the bicycle. Braces maybe affixed to the support adjacent to the hooks to brace the wheels to limit the rotation of the stem and headset. The support may be attached to a mount to mount the support to a vehicle.
System 200 may further include fasteners to fasten removably the front and rear wheel to the hooks or suspenders. System 200 may further include a sway limiter to limit the sway of the bicycle around the axis formed between the front and rear wheel hooks. Other embodiments disclosed herein may show other types and configurations of hooks, suspenders, fasteners, braces, sway-limiters, mounts and other parts of the system.

FIG. 12D shows a cross sectional view illustrating the portion of a rack that allows for expanding the rack through the line L of FIG. 12B. (For an overview of bicycle racks extended by hitching frames together see FIG. 4)
Considering FIG. 12A to D together, hitching system 800 includes upright-mount 802 that is fixedly connected to upright-receiver 804, as shown. Upright-support 828 may have the same size and shape periphery as upright-mount 802, as shown. Upright-support 828 may insert into upright-receiver 804, as shown. Upright-support 828 may rest upon upright-mount 804 when upright-support 828 is inserted into upright-receiver 804, as shown.
Perpendicular-support 814 may be fixedly attached to coupling 818, as shown. Bracket 820 may be fixedly attached to perpendicular-support 814 and coupling 818, as shown. Perpendicular-ridges 824 may be integral with bracket 820, as shown. In alternate embodiments, perpendicular ridges 824 may be used without bracket 820. Upright-ridges 822 may be disposed along the open end of coupling 818, as shown. Coupling 818 may be sized to mate with upright-receiver 804 being sized just larger than the periphery of upright-receiver 804. Coupling 818 may rest upon upright-receiver 804 by resting on upright-receiver 804 with the load also placed on upright-ridges 822 and perpendicular-ridges 824, as shown. Ridges may be any type of restraining face or restraining member that may resist pressure in the direction perpendicular to its face.
Upright-receiver 804 may have set of apertures 806, as shown. Perpendicular support 814 may have set of apertures 816, as shown. Upright-support 828 may have set of apertures 826, as shown. Set of apertures 806. set of apertures 816, and set of apertures 826 may be positioned such that a locking-bolt 808 may be inserted through all six holes simultaneously when hitching system 800 is in the assembled position, so that hitching system 800 may be locked so that it will not come apart, such as, for example, during travel of a vehicle. Locking-bolt 808 may have bolt-head 814 and cotter pin 810 which may removeably hold locking-bolt 808 in place.
Hitching system 800 allows each portion of the system to be assembled while being held in place by gravity. For example, starting from the unassembled state, upright-support 828 may be placed within upright-receiver 804 and rest upon upright-mount 802 using gravity. After positioning upright-support 828, no manual or dexterous assistance is needed from the person hitching the frames together. Next, coupling 818 of perpendicular-support 814 may pass by upright-support 828 and over upright-receiver 804 before dropping down upon upright-receiver 804, as shown. Coupling 818 may be held in place by interlocking forces along upright-ridges 822 and perpendicular-ridges 824, as shown. Again, perpendicular-support 814 may be held in place using gravity and without manual assistance. Alternately, perpendicular-support 814 may be positioned before upright-support 828, thereby allowing the assembler to assemble whatever piece is the most convenient or handy. Finally, locking bolt 808 may be inserted through the sets of apertures 806, 816, 826, as shown. Hitching system 800 may allow for one handed assembly, which may require less dexterity on the part of the person assembling.
In an alternate embodiment, perpendicular support 814 may be required to be placed prior to upright-mount 802, which may allow coupling 818 to completely encircle upright-receiver 804, and thereby eliminate upright-ridges 822.
