FIELD OF INVENTION
This invention relates to small animals, and in particular to devices, apparatus, systems and methods for providing a double bearing, not noisy, injection molded exercise wheel for small animals, including marsupium's such as sugar gliders, as well as mice, rats, gerbils and dwarf hamsters, and the like, with no exposed mounting hardware, which safely holds animals within, and allows for waste to fall out.
BACKGROUND AND PRIOR ART
Exercise wheels have been used over the years that allow for small animals, including marsupium's such as sugar gliders, as well as mice, rats, gerbils and dwarf hamsters, and the like, to use, and have generally been metal type wheels, with exposed mounting hardware. However, these wheels have many problems. For example, many of these wheels are made from metal parts, coated with paint, that can wear off over time. The prior art wheels can often have cage type openings and cross-bars that can allow for feet, tails and legs to pass through that can result in harm to the small animals.
There are also safety issues with the prior art wheels. The floor type openings in these wheels and additional side openings can also cause the small pets to fall out of the rotating wheel and accidentally banging their heads on nearby shelves or types if the small animal tries to exit through the small holes as the wheel is spinning.
Additionally, most of these cage type wheels have exposed mounting hardware which results in the rotating wheel to generate squeaky noises not only during the day but all night long as the wheel is being rotated. As such, these prior art wheels can become both annoying and undesirable over time in view of the noise being generated by the rotating wheels.
Thus, the need exists for solutions to the above problems with the prior art.

To the rear of one of the bearings 50 can be a longer bushing 52, such as but not limited to another stainless steel bushing, and the like, which spaces the hub portions of the wheel 10 from the top of the stand 70. An elongated fastener 60 such as a bolt or screw can attach the wheel 10 into the top cap 72 on the main upright tube 74 of the stand 70, with a nut 65 on another side of the cap 72 and washer 56 on opposite side of the cap 72.
Referring to FIGS. 2A-2B, the rear wall 16 can have a generally convex shape facing the upright support tube 74 which can function as a safety feature so as to help prevent animals from becoming trapped in the space between the rear wall 16 and support tube 74.
Referring to FIGS. 1A-3, the U shaped stand 70 will now be described. The bottom of the main upright tube 74 can frictionally fit into the top of a T fitting 76. Rear support tubes 78 can attach into both sides of the T fitting 76. A left leg tube 80 can be attached to one of the rear support tubes 78 by a left coupler 82, and have an end cap 84 on the outer end of the left leg tube 80. A right leg tube 90 can be attached to another one of the rear support tubes 78 by a right left leg coupler 92 and have an end cap 94 on the outer end of the right left leg tube 90. The U shaped stand 70 can allow for the wheel 10 to be supported on any generally flat surface, such as a table top, countertop, shelf or floor. The U-shaped stand 70 components can be formed from PVC types pipes, and the like.
The novel exercise wheel can be used for travel cages, and can be used for small animals, such as marsupium's such as sugar gliders, as well as mice, rats, gerbils and dwarf hamsters, and the like,
The wheel and stand can be approximately 11 & 1⁄2 inches tall, and be approximately 111⁄2 inches tall, approximately 91⁄2 inches wide, approximately 6 inches deep.
