Flexible protective bicycle cover for transport on a vehicle carrier

A flexible protective cover constructed of elastic stretchable material to continously cover a bicycle seat, crossbar, handle bars and the front fork of a bicycle when mounted on a car top carrier. The cover can be provided to fit the bicycle either with or without the front bicycle wheel attached to the bicycle.

BACKGROUND OF THE INVENTION 
This invention relates to a flexible protective cover for use on a bicycle 
while transported by a vehicle. The cover provides protection for the 
seat, handle bar portion and front fork portion of the bicycle from dust, 
bugs, grime, dirt and water while traveling. It provides a streamlined 
shape as a result of using a conforming stretchable material that extends 
from the seat, over the handle bars and down to the bottom of the front 
fork. 
Typically, most bicycle riders do not cover their bicycles while 
transporting them on automobile roof carriers, trailers, bumper carriers 
or otherwise. With increasingly complex bicycle technology and consequent 
higher costs (in the thousands of dollars for professional racing 
bicycles) it becomes increasingly more important to protect the critical 
or sensitive bicycle parts from damage or soiling due to travel related 
contaminants. 
To this end, a flexible protective cover for drive train elements of a 
bicycle is disclosed in U.S. Pat. No. 4,632,416, issued on Dec. 30, 1986. 
This cover protects only the front drive sprocket, the chain and the rear 
sprocket and adjacent gear shift mechanisms. Alternatively, entire bicycle 
covers have been sold for a number of years which envelope the entirety of 
the bicycle. Such covers serve the purpose of protecting expensive bicycle 
parts from damage or soiling, but are intended for use only while the 
bicycle is being stored. They would present a serious problem if used when 
transporting a bicycle on top of a car, since cross-winds striking the 
large expanse of fabric would likely push the bicycle laterally, causing 
serious damage to the bicycle and/or the bicycle carrier. 
Therefore, it is the purpose of this invention to provide a cover that 
protects the bicycle from airborne objects and contaminants while 
traveling at highway speeds, while not subjecting the bicycle to 
destabilizing lateral forces. 
SUMMARY OF THE INVENTION 
The apparatus of the present invention is in the nature of a flexible cover 
attached to a bicycle that is being transported by a vehicle, such as when 
mounted on a car top bicycle carrier. The cover is made of a stretchable 
material and has waterproof portions adapted to keep the seat dry while 
being transported. In one embodiment, this invention includes a cover to 
protect the seat, the crossbar, the handle bar portion and extends down to 
the front yoke and fork. In a second embodiment, the cover protects only 
the seat, cross bar and handle bar portions. This embodiment can be used 
when the front bicycle wheel is left on the bicycle during transportation, 
thereby protecting the upper portions of the bicycle. 
The stretchable material is used to tightly envelope the protected portions 
and maintain the cover over the seat, handle bar and yoke of the bicycle 
and prevent flapping or flutter when traveling at highway speeds. The 
stretchable material may have elastic means sewn into the periphery to aid 
in gripping the seat and handle bar portions. Because of its minimal use 
of fabric, the cover of this invention has a small cross-wind profile, 
when viewed from the side, thereby minimizing the tendency for the bicycle 
to topple sideways in a cross-wind. While the car is in motion the front 
profile of the cover shields all major bicycle parts except the pedals 
from road grime and objects approaching the bicycle from the front 
quadrant of the bicycle.

DETAILED DESCRIPTION OF THE INVENTION 
Referring to FIGS. 1 and 2, the flexible bicycle cover 10 is illustrated in 
its installed position on a bicycle 12. The cover 10 comprises a 
continuous piece of stretchable material consisting of a seat cover 
portion 14, a handle bar cover portion 16 and a front fork cover portion 
18. The bicycle 10 is mounted on a car top carrier 20 which is securely 
fastened to a car roof 22. The bicycle 10 is releasably affixed to the 
carrier 20 with at least one quick release skewer 24. 
The seat cover portion 14 slips over bicycle seat 26 and is held securely 
in place by elastic attachment means 28 that run continuously from one 
side of the handle bar cover portion 16, around the back and underside of 
seat 26 to the opposite side of handle bar cover portion 16. The cover 
illustrated in FIG. 1 is preferably utilized when the front bicycle wheel 
has been removed for easier transportation of the bicycle 12. As can be 
seen in FIG. 2, with the exception of the drive train 30, the front 
profile of the flexible bicycle cover 10 shields the bicycle from highway 
contaminants as the car travels in a forward direction. 
FIG. 3 illustrates the details of construction of the bicycle cover 10. 
Seat cover portion 14 is provided with a waterproof seat pocket member 40 
and a waterproof seat cover 42. The waterproof seat cover 42 repels water 
from the seat while in transit. The front horn portion of bicycle seat 
slips into seat pocket member 40 to maintain the flexible cover 10 in 
place over the seat 26. Elastic means 28, which may be in the form of a 
conventional shock cord, extends continuously around the handle bar cover 
portion 16 from 44, around the seat cover portion 14 and back around 
handle bar portion to 46. The seat cover portion 14 and handle bar portion 
16 are continuously interconnected with fabric tongue 47, which covers 
crossbar 49. The front fork cover portion 18 is provided with a pair of 
apertures 48 that are engaged by a skewer 24 to hold the flexible cover 10 
in position on the bicycle while in transit. The front fork cover portion 
18 is provided with a reinforced portion 50. For example the stretchable 
fabric material 52 may be folded upon itself and sewn to provide 
additional strength. A pair of loops 54 are provided to secure the front 
fork cover portion 18 behind the front fork of the bicycle during transit. 
The loops 54 may be fastened by any conventional means, such as 
hook-and-pile fasteners sold under the Velcro.TM. trademark, by snaps or 
by inserting a string 56 through each loop 54 and tying a knot. Pockets 58 
are formed in the handle bar cover portion, as by sewing extra pieces of 
stretchable material 52 into the flexible cover 10. Such pockets are 
necessary in order to tightly enclose the handle bars and brake levers of 
the bicycle 12. 
FIG. 4 illustrates a cross-section of the seat cover portion 14, with 
stretchable material 52 rolled over at the edge 70 to enclose elastic 
means 28, gathered, and then sewn with thread 72, through the waterproof 
seat cover 42. 
A second embodiment of the flexible protective cover 10 is illustrated in 
FIG. 5. The seat cover portion 12 and the handle bar cover portion 14 are 
identical, however no front fork cover portion 18 is provided. By 
terminating fabric 52 and connecting the elastic means 28 between points 
44 and 46, the device of FIG. 3 may be modified into the embodiment of 
FIG. 5. The flexible cover 80 of FIG. 5 is used on a car top mounted 
bicycle 82 transported with the front wheel 84 in place. The cover 80 
comprises a similar seat cover portion 86 which is contiguous with handle 
bar cover portion 88 by virtue of fabric tongue 89. The flexible cover 80 
protects only the upper portions of bicycle 82 while mounted on car top 
bicycle rack 20 attached to car roof 22. 
Referring to FIG. 6, a third embodiment of the invention comprises a split 
front fork cover 90 installed on a bicycle with the front wheel in place. 
The front fork cover portion 92 comprises a pair of cover members 94, 96 
which extend on either side of wheel 84 in front of and adjacent each of 
the forks. The members 94, 96 attach to the bicycle at skewers 98. 
FIG. 7 illustrates in plan view the location of members 94, 96. This 
embodiment may be utilized in the manner disclosed in FIG. 1 by securing 
the members 94, 96 to one another by snaps, Velcro.TM. strips, buttons or 
other means well-known to those skilled in the art, and by securing the 
portions 94, 96 to the frame through apertures 48. 
The cover 10 illustrated in FIG. 3 can be installed on a bicycle having the 
front wheel 84 in place (as illustrated in FIG. 5) by folding the front 
fork cover portion 18 under the handle bar portion 16 and tying loops 54 
together around any convenient bicycle part in the handle bar area. 
The waterproof seat portions can be made from any strong, flexible 
waterproof coated material. The preferred material for the stretchable 
material is a blend of an elastic fiber and Nylon.TM. in the ratio of 
about 15:85% respectively. However, blends of from about 5-25% elastic 
fiber and from about 75-95% Nylon.TM. are operative. It is to be 
understood that the cover of the present invention must be provided in a 
stretchable material to acquire the benefits set forth herein. 
While a preferred embodiment of the invention has been disclosed, various 
modes of carrying out the principles disclosed herein are contemplated as 
being within the scope of the following claims. Therefore, it is 
understood that the scope of the invention is not to be limited except as 
otherwise set forth in the claims.
