Abstract
A fabric is cut, sewn, and furnished with Velcro or other hook and loop fastener portions to become a cover to be removably positioned about a drive mechanism of a bicycle to protect this drive mechanism from the accumulation of dirt. A back elevational side of this fabric cover has spaced circular cuts with access cuts to these spaced circular cuts, thereby forming an access flap. These cuts accommodate the fitting of this back elevational side about both the rear axle and the pedal axle, and alongside the drive chain and the sprocket of a bicycle. After the fitting of this back elevational side about a rear axle and a pedal axle, Velcro fastener portions are used to keep the access cuts closed together when this cover is in use. A front side, which is continuous throughout, is thereafter secured to the back elevational side, where not previously initially sewn together to make this cover, by using components of Velcro fasteners. Preferably a Velcro strap is used to keep a rear bicycle wheel from rotating, as this Velcro strap of this cover is passed around a spoke of a bicycle wheel.

Description
Background
There has always been a need to try to keep the drive mechanisms of bicycles clean to prevent unnecessary wear otherwise caused by dirt that accumulates in these drive mechanisms. In 1894 Walter Biddles in his U.S. Pat. No. 531,254 illustrated and described his gear case which was essentially all metal and permanently mounted on a bicycle frame to cover the bicycle drive mechanisms. Then in 1897 William C. Humphrey in his U.S. Pat. No. 594,694 disclosed his dress and mud guard which also was essentially all metal and permanently mounted on a bicycle frame to the bicycle drive mechanism.
In 1976 Messrs. Weed and Mougel, in their U.S. Pat. No. 3,968,913, illustrated and described their protective fabric cover for an automobile mounted bicycle carrier. Their fabric cover completely covered the entire bicycle. Openings provided in the flexible fabric material of the cover cleared portions of the automobile bicycle carrier and also strap portions used to secure the bicycle to this carrier. This fabric cover had a top opening to receive the bicycle. A top flap secured subsequently by a Velcro fastener completed the protection of the entire bicycle from the ambient environment.
Later, in 1983, Joseph G. Profeta in his U.S. Pat. No. 4,378,883, disclosed his bicycle carrying case made of vacuum formed plastic resin material, originally available in sheets. Two complete formed sides were hinged together to completely cover a bicycle. Fasteners were used to keep the cover sides together. Openings were provided to receive hangers either mounted on vehicles or on dwellings, and to receive a person's hands, or shoulder straps. The interior of this complete case was padded. Another embodiment was made as a unitary overall member having an integral hinge between the sides.
These past permanent covers, for covering only the drive mechanism of bicycles, and the full covers of bicycles are recognized as serving their respective purposes very well. There remains a need, however, for a low cost, easily made, easily installed, easily removed, and readily cleaned, fabric cover to place over the drive mechanism of bicycles, when they are being transported on a vehicle or stored while awaiting the next bicycle trip, to keep the drive mechanism clean.
Summary
The drive mechanism of a bicycle is conveniently protected from the accumulation of dirt during transport and/or storage of a bicycle, by using a fabric cut, sewn, and furnished with Velcro or other hook and loop fastener portions, to be conveniently installed and conveniently removed, using the hook and loop fastener portions. This fabric cover is readily cleaned and compactly stored when not in use.
The fabric cover is installed by first positioning the back elevational side thereof inside the gears, derailleur, chain, and sprocket, and about both the rear axle and pedal axle, utilizing a flap portion formed by vertical cuts, and circular cuts, made in this back elevational side. Then the cuts are secured by using respective hook and loop fastening portions. Thereafter, a front elevational continuous side is placed over the gears, derailleur, chain and sprocket and secured to the back elevational side by respective hook and loop fastening portions, to thereby complete the protective covering of a drive mechanism of a bicycle.

Description
The conveniently installed and removed fabric protective cover 10 for the drive mechanism 12 of a bicycle 14, illustrated in a preferred embodiment in all the FIGS. 1 through 4 of the drawings, when installed, keeps the drive mechanism 12 of a bicycle 14 free of dirt during the transport or storage periods of the bicycle 14. In FIG. 1, this fabric protective cover 10 is shown installed around the drive mechanism 12 of a bicycle 14. Preferably when installed, the rear bicycle wheel 16 is kept from rotating by placement of the loop 18 of this cover 10 about a spoke 20 of the wheel 16, as illustrated in FIG. 2.
This fabric protective cover 10 is shown in FIG. 3 as it is arranged for storage when not in use, with the exception of showing the final securing of some of the hook and loop fastener interfitted portions 22, 24. The exterior 26 of the back elevational side 28 of this cover 10 is illustrated to show the circular opening 30 which is fitted about the rear axle 32 of the bicycle; the circular opening 34 which is fitted about the pedal axle 36 of the bicycle 14, the respective access vertical cutouts 38, 40, providing access to the circular openings 30, 34, and in so doing creating the access flap portion 42 of this back elevational side 28 of the cover 10.
The cutout 38 for reaching the circular opening 30 is securely covered and closed by using the overall Velcro or other hook and loop fastener 44, having the respective interfitting portions 22, 24 of a Velcro fastener. The cutout 40 for reaching the circular opening 34 is securely covered and closed by using the overall Velcro fastener 46, having the respective interfitting portions 22, 24, of a Velcro fastener. These overall Velcro fasteners 44, 46 are shown in their opened positions in FIG. 3.
The loop 18, which is utilized to be passed around a spoke 20 of a rear bicycle wheel 16 and secured to this fabric protective cover 10, is equipped with an overall Velcro or other hook and loop fastener 48 having respective interfitting portions 22, 24. This loop 18 is secured at one end at all times to the access flap portion 42 of this back elevational side 28 of this cover 10, as particularly shown in FIGS. 3 and 4. When this loop 18 is secured about the spoke 20 of the rear bicycle wheel 16, this wheel 16 will not be able to turn around in many rotations, when the wind is blowing, as a vehicle carrying the bicycle on a bicycle rack is underway. If no loop 18 is available or the loop 18 is not secured, then the rotating wheel 16 is often able to partially dislodge this full fabric protective cover 10.
The continuous front elevational side 50 and the back elevational side 28 of this fabric protective cover 10, are preferably, sewn together along their common bottom edges 52, 54, along their common front edges 56, 58, and along their common back edges 60, 62, as particularly shown in FIGS. 3 and 4. Then their oppositely positioned top edges 64, 66 are closed together by an overall Velcro or other hook and loop fastener 68 having the respective interfitting portions 22, 24, as shown in FIG. 3.
The start of the placement of this removable fabric protective cover 10 about the drive mechanism 12 of a bicycle 14 is illustrated in FIG. 4. All of the overall Velcro or other hook and loop fasteners 44, 46, 48, and 68, are in their open positions of their respective interfitting portions 22, 24. The back elevational side 28 is being placed behind the gear assembly 70, derailleur 72, chain 74. Then by utilizing the circular opening 30 for the rear axle 32 and the cutout 38 for reaching this opening 30, portions of this cover 10 are placed about the rear axle 32.
Subsequently, but not shown, this placement is continued by utilizing the circular opening 34 for the pedal axle 36 and the cutout 40 for reaching this opening 34 to place portions of this cover 10 about the pedal axle 36. These placements, in reference to the circular openings 30, 34, and rear axle 32 and pedal axle 36 are completed by the respective closings of the respective overall hook and loop fasteners 44, 46, which respectively close the cutouts 38 and 40.
Then the overall hook and loop fastener 68 is utilized to join the oppositely positioned top edges 64, 68 of the back elevational side 28 and the continuous front elevational side 50 to complete the closure of this full fabric protective cover 10 about the drive mechanism 12 of the bicycle 14. Preferably, the final step is undertaken to place the loop 18 about a spoke 20 of the rear wheel 16 of this bicycle 14, to keep this wheel 16 from rotating relative to this fabric protective cover 10, when it is in its protective covering position preventing the accumulation of dirt on the drive mechanism 12, when the bicycle 14 is being transported or stored.
