BACKGROUND
This invention relates to an apparatus that is attached to a bicycle as a
means of
exercising one or more dogs at a time.
A common problem in urban areas is that dog owners have difficulty giving
their
dogs adequate exercise. Walking dogs on a leash, especially the larger breeds,
may not allow them to get sufficient exercise. While off-leash exercise is
ideal,
off-Icash areas may not be conveniently located and/or their hours of use may
be
limited to certain times of the day.
Some people solve the problem of exercising their dogs by riding a bicycle
with
the dog running alongside and the cyclist either holding the end of the leash
or
attaching it to the handlebars. This method is unsafe for the cyclist, the
dog, and
others on the road. By having to watch out for the dog and keep the bike
steady,
the cyclist may be distracted from keeping an eye on trra.ffic and road
obstacles.
As well, the dog can easily knock or pull the bike over, possibly injuring the
cyclist;
if the dog gets away, it can get hit by a car or cause an accident. Even if
one
avoids=areas with vehicle traffic and rides along a path or trail, the dog and
bike
may take up too much space widthwise, making it difficult for others on the
trail to
pass. Another problem with exercising dogs in this way is that only one dog at
a time
can be exercised,
I have found that these disadvantages may be overcome by attaching an
apparatus
to the bike that allows one or more dogs to be exercised while leashed at the
rear of
the bike. With the dogs secured in this way, there is little chance of them
being
able to pull or knock the bike over or to get free; the cyclist, being better
able to
concentrate on the road, can ride more safely. As well as allowing one to
exercise
more than one dog at a time, using the device takes up less space on the road
widthwise than if the dog runs alongside the bike.
SUMMARY OF INWNTION
This invention provides for a canine-exercising apparatus attachable
to a bicycle.
One aspect of the invention provides for right and left support anns
attached to and extending rearwardly from rear frame members of a bicycle.

CA 02433995 2007-02-02
lA
Right and left swing arms are attached to the right and left support anns,
respectively. A harnessing means for accepting at least one leash is attached
to each of the swing arms. The swing arms are attached to the support arms
in either a first position for use wherein the swing arms extend rearwardly
from the support arms beyond the rear of the rear wheel of the bicycle, or a
second position for storage wherein the swing arms extend generally
upwardly from the support arms beyond the top of the rear wheel. The swing
arms may be pivotable between the first and second positions. The swing
arms may be removably attached to the support arms. The support arms may
be removably attached to the rear frame of the bicycle, and removably
attached to each other.
Further aspects of the invention provide for harnessing means
comprising at least one ring. The harnessing means may also comprise
shock-absorbing components, such as expansion springs between the rings
and the harnessing means. The support arms optionally include an
abrasion-resistant surface. For example, rubber sleeves may be provided for
the support arms.

DETAILED DESCRIPTION OF THE INVENTION
In the embodiment of the Canine Bike Exerciser illustrated in Figures 1, 2,
and 3, the
invention comprises a device attached to a bicycle frame that allows one to
exercise one
or more dogs at a time by having them run with the bicycle while being leashed
at the
rear. The device comprises a primary component, shown in Figures 1, 2, 3, and
4, made
from steel tubes 1, which are attached to a bicycle frame by means of nuts and
bolts 2 and
zip straps 3.
The tubes 1 are flattened at the ends, where holes are drilled to allow for
the passage of
bolts 2, 4a, and 4b. Rubber sleeves 5 are slipped onto each of the tubes 1 at
the points
where the tubes 1 come in contact with the bicycle frame in order to lessen
the possibility
of abrasion on the frame.
The device also comprises a secondary component, shown in Figures 1, 2, 3, 5,
6, and 7,
made from steel tubes 6 flattened at the ends, where holes are drilled to
allow for the
passage of bolts 4a, 4b, and 7. At the distal end the tubes 6 are bent at
right angles where
they are attached by nuts and bolts 7 to a wooden joining element 8; at the
proximal end,
the steel tubes 6 of the secondary component are connected to the steel tubes
1 of the
primary component by bolts 4a and 4b, and wing nuts 9. The bolts 4a and 4b are
passed
through the corresponding holes in the steel tubes 1 of the primary component
and the

CA 02433995 2005-07-29
3
steel tubes 6 of the secondary component from the medial side so that bolts 4a
and 4b can
be secured by wing nuts 9 on the lateral side of the bolts 4a and 4b. Placing
the wing nuts
9 on the lateral side allows the bolts 4a and 4b to be easily removed in order
to detach the
secondary component from the primary component should one want to remove the
secondary component when the Canine Exerciser is not in use, as seen in Figure
4.
Alternatively, one can remove only one set of bolts 4a, allowing one to
position the
joining element in a forwardly facing direction superior to the rear bicycle
wheel, as
illustrated in Figure 3.
As seen in Figures 1, 2, 3, 5, 6, and 7, the bolts 7 joining the steel tubes 6
of the
secondary component to the wooden joining element 8 are passed through the
joining
element 8 from the distal to the proximal side, where the bolts 7 are secured;
thus the
bolts 7 protrude on the opposite side of the joining element 8 to where the
dog(s) are
leashed, eliminating the chance of injury to the dog(s).
Figures 1, 3, 6, and 7 show in detail the elements of the Canine Bike
Exerciser that enable
one to leash a dog or dogs to the apparatus. Eye screws 10 are inserted into
the top of the
wooden joining element 8; an expansion spring 11 is connected to each eye
screw 10; a
harness ring 12 is attached to each expansion spring 11. The leash of a dog
being
exercised is looped through the harness ring.
The arrangement of components on the joining element 8 has been done with the
utmost
regard for the safety of the dogs: rounded edges on a wooden joining element
8,
placement of eye screws 10 on top of the wooden joining element 8 to minimize
the
chances of contact with the dog(s), expansion springs 11 that minimize yanking
on the
dog's neck, round harness rings 12 (that is, no sharp edges that could injure
the dog(s).
Having thus described the present invention, it is thought that said invention
and its
advantages will be understood from the foregoing description, and it will be
evident that
various changes to said invention may be implemented without departing from
the spirit
and scope of said invention or sacrificing all of its material advantages;
that is, the
foregoing description is merely a preferred or exemplary embodiment of said
invention.
