Abstract

The present invention is a bicycle roller system with roller pins specially shaped to accommodate the beginning cyclist. The pins are parabolic in shape, with the center of the roller pins having the smallest circumference and the two ends of the roller pins having the greatest circumference, affording the cyclist added balance and natural positioning in the center of the roller pins. The amateur cyclist can now feel confident mounting the once intimidating bicycle roller system knowing that his maintained balance is a natural design feature of the system. Another difference between the present invention and the prior art is the fact that the present system does not require a plurality of supports between the system and the surface on which it stands in order to prevent contact between the roller pins and the surface. The side rails of the present invention are of sufficient height as to disallow the roller pins from rubbing the mounting surface.

Self supported bicycle roller system

A bicycle roller system of the type in which a frame carries rollers arranged to support the wheels of a free-standing bicycle to permit the bicycle to be operated on the rollers in a conventional manner, i.e., with all motive power and lateral balancing of the bicycle being supplied by its operator. In the bicycle roller system disclosed herein, the frame is formed of side rails that mount the rollers at adjustable intervals along the length of the frame to accommodate various bicycle and wheel sizes.

Bicycle roller systems provide great exercise and training to both the professional and amateur cyclist, teaching the rider both balance and endurance. However, the traditional bicycle roller systems prove difficult for the beginner to use in that he is not supported and has to rely on his own balance to maintain a riding stance or promptly fall off the roller system and risk injury as he crashes to the floor. Unlike the prior art, the present invention is a bicycle roller system with roller pins specially shaped to accommodate the beginning cyclist. The pins are parabolic in shape, with the center of the roller pins having the smallest circumference and the two ends of the roller pins having the greatest circumference, affording the cyclist added balance and natural positioning in the center of the roller pins. The amateur cyclist can now feel confident mounting the once intimidating bicycle roller system knowing that his maintained balance is a natural design feature of the system. Another difference between the present invention and the prior art is the fact that the present system does not require a plurality of supports between the system and the surface on which it stands in order to prevent contact between the roller pins and the surface. The side rails of the present invention are of sufficient height as to disallow the roller pins from rubbing the mounting surface.

Figure 1 Bicycle roller system with bicycle

Figure 1 consists of a bicycle roller system including two side rails 110, three roller pins 120, a plurality of roller pin fittings 140, and a bicycle 150.

Roller pins 120 are constructed preferably of stainless steel and are placed into roller pin fittings 140 inherent in the two metal side rails 110 such that the roller pins 120 perfectly fit the dimensions of the user's bicycle. The height of the side rails 120 keep the roller pins 120 a sufficient distance above the ground to prevent contact.

The cyclist mounts the bicycle on the bicycle roller system and begins pedaling. Balance is lent to the cyclist via the special design of the roller pins 120, as seen in Figure 2.

As seen in Figure 2, the three roller pins 120 of the bicycle roller system are designed such that the center of their lengths have the smallest circumference, with the outer ends having the greatest circu...
