SPRING-BASED EXERCISE CYCLE
The invention includes an exercise cycle having an upright frame and a spring assembly capable of permitting at least a portion of the upright frame to move or shift in a lateral side-to-side direction or a front-to-back direction. The exercise cycle includes a pair of front legs depending from a forward portion of the exercise cycle and a pair of rear legs depending from a rear portion of the exercise cycle. Each of the front legs and rear legs have a proximal section adjacent to the upright frame that is spaced a distance from a distal section by a spring.

FIELD OF INVENTIONThe present invention generally relates to exercise equipment, and in particular, a spring-based exercise cycle permitting side-to-side and front-to-back movement.
BACKGROUNDExercise equipment such as treadmills, elliptical trainers, stair climbers, rowing machines, and stationary bikes have become increasingly popular. In particular, stationary exercise bikes are used in many different locations including in health clubs, gyms, or at home. Different types of exercise bikes have been designed for different uses.
Generally, the frame of the conventional stationary exercise bicycle is rigidly mounted at a fixed position. This makes it difficult to simulate the actual riding of a bicycle and the health effects associated therewith. For example, one important component is for a rider is to engage his or her core and abdominals while bicycle riding. Oftentimes, core engagement is required when a bicycle rider “corners” a turn or leans with the bike laterally. Accordingly, some exercise equipment has been developed which allows the user to sway laterally side-to-side in an attempt to better simulate the actual realistic experience of riding a bicycle. This conventional equipment, however, uses hydraulics or a movable platform base which does not adequately simulate the actual effects of “cornering” or leaning and do not provide the same health benefits or core engagement of actual riding.
Accordingly, an invention is needed which overcomes these drawbacks and provides improved exercise equipment which permits leaning side-to-side or front-to-back movement and promotes core engagement.
SUMMARY OF THE INVENTIONThe present invention is directed to exercise equipment, such as an exercise cycle, that permits a rider to move or shift the equipment laterally side-to-side or front-to-back so as to more realistically simulate bicycle riding and promote core engagement. The exercise cycle can include an upright frame which has a forward section and a rear section. A longitudinal axis can extend from the rear section to the forward section along a path that is generally parallel to the ground. Additionally, the exercise cycle can also include other cycle components such as handlebars, pedals, wheels or other components as are generally known in the art.
The upright frame includes depending legs which extend downwardly to form a base in contact with the ground. Generally, the upright frame can have at least two pairs of depending legs which are operatively connected with a spring configuration for permitting the upright frame to move laterally side-to-side with respect to the longitudinal axis or front-to-back in response to movement by a user.
The spring configuration can include a spring, coil, or other bias element that is arranged and secured to each leg of the two pairs of depending legs. In particular, each of the depending legs can include a proximal portion adjacent to and secured or integrally attached to the upright frame. The proximal portion includes a fastener assembly which is adapted for securing an upper portion of the spring, coil, or other bias element. Each of the depending legs also includes a foot distal from the upright frame and spaced a distance from the frame by the spring, coil, or other bias element. In particular, the foot includes an assembly that is adapted for securing a lower portion of the spring, coil, or other bias element. Accordingly, the spring configuration, which in this example includes four separate springs, permits the upright frame to move laterally side-to-side or front-to-back in response to movement by a user.
The present invention provides for an apparatus and method of using a stationary exercise cycle that has a spring-based system to permit a cycle rider to move or shift the exercise cycle in a lateral side-to-side or front-to-back motion while pedaling or riding.
Referring to
The upright frame 102 of the exercise cycle 100 has a forward portion 104 and a rear portion 106. In general, convention exercise cycle components such as handlebars, a monitor screen, resistance knob, or other components may be attached to the forward portion 104 as is known in the art. The rear portion 106 may include a cycle seat for the rider or other components as are generally known. As shown in
The spring configuration 200 is secured to legs depending from the upright frame 102. In one example, and referring to
Each of the legs 108, 110 include a proximal leg portion 114 and a distal leg portion 116 that are spaced a distance from one another by a spring 118. The proximal leg portion 114 is adjacent to and secured or integrally attached with the upright frame 102. It may be integrally attached or secured through welding, fastening or other ways known in the art.
The forward depending legs 108 and rear depending legs 110 may have various configurations as is known in the art. For example, as shown in
The spring 118 may be secured or fastened to legs 108, 110 using various assemblies. For example, a fastener assembly 202 may be used to secure an upper portion of the spring 118 to the proximal leg portion 114. A foot fastener assembly 204 may be used to secure a lower portion of the spring 118 to the distal leg portion 116.
Referring to
The post piece 120 can be used to secure the spring 118 as shown in
Referring to
The clamp 126 also includes a support frame 128 for engaging the proximal leg portion 114 or cross-members 218, 220 and providing additional stability to the exercise cycle 100.
Referring to
The post piece 210 can be used to secure the spring 118 as shown in
Referring to
As described herein, the spring configuration 200 includes a spring 118 arrange on each of the four legs 108, 110 thereby permitting a rider to lean and shift or move the upright frame 102 in a generally lateral side-to-side direction or front-to-back direction. Referring to
A rider can shift his or her weight in the forward direction. In this example, the springs 236, 240 on each of the forward legs 108 are compressed, at least in part, by the weight of the rider while the springs 238, 242 on each of the rear legs 110 extend. This configuration causes the forward portion 104 to tilt downward while the rear portion 106 shifts upward so as to simulate a downhill ride. Similarly, when a rider shifts his or her weight in the rear direction, the springs 236, 240 on the forward legs 108 extend and the springs 238, 242 on the rear legs 110 are compressed. This configuration causes the rear portion 106 to tilt downward while the forward portion 104 shifts upward so as to simulate an uphill climb.
