Abstract
A device that can be ridden for recreation and exercise. The device has an upright annular spring body member with a seat and a handle on the upper segment of the body annulus. In use, the rider straddles the device and with his feet planted on the riding surface, flexes his legs to impose his weight on the device to store energy therein. This cycle is followed by the rider extending his legs to release the stored energy. This jouncing sequence is repeated and the rhythmic build up of energy causes the device and its rider to be bouncingly propelled across the riding surface. In a second embodiment, stirrups are provided in the lower segment of the body annular for the rider's feet. In a third embodiment, the body member has supports for the rider's feet suspended from the seat.
Claims16
A device adapted to be ridden for recreation or exercise, said device having resilient means for propelling said device bouncingly across the riding surface comprising:
- a thin solid resilient upright non-metallic annular spring body member having its axis located in the horizontal plane, said spring member having an upper top segment, a lower bottom segment in direct contact with a reacting directly against the surface on which the device is to be ridden, and a pair of opposing substantially ellipsoidal ends, the distance between said ends being less than the distance between said upper and said lower segments, said annular spring having nearly constant flexural and stiffness properties throughout the entire annulus;
- handle means to be grasped for support by the rider of said device, said handle means being fixed at least on said upper segment;
- and
- seat means fixed on the radially outer surface of said upper segment proximate said handle means such that said device can be straddled by a rider with his feet in contact with the riding surface and wherein the elasticity of said spring member is such that said rider, by following an operating sequence in which he stores energy in the spring member by flexing his legs to impose his weight thereon and releases said energy to do work by extending his legs, can use the elasticity of said spring member to propel the device and himself bouncingly across said surface.
A device adapted to be ridden for recreation or exercise, said device having resilient means for propelling said device bouncingly across the riding surface comprising:
- a thin solid resilient upright non-metallic annular spring body member having an upper segment, a lower segment in direct contact with and reacting directly against the surface on which the device is to be ridden, and a pair of opposing substantially ellipsoidal ends, said annular spring having nearly constant flexural and stiffness properties throughout the entire annulus;
- seating means on said upper segment;
- and
- handle means proximate said seating means, wherein said device can be straddled and said handle means used for support and wherein the elasticity of said spring member is such that a rider by following an operating sequence in which he stores energy in the spring member by bending his legs to impose his weight thereon and releases said energy to do work by extending his legs, can use the elasticity of said spring member to cause the device and himself to be propelled bouncingly across said surface.
A device adapted to be ridden for recreation or exercise, said device having resilient means for producing vertically directed oscillations, and wherein said resilient means comprises:
- a single continuous one-piece thin solid resilient upright non-metallic annular spring serving as a body member and having an upper segment for the seating of a rider and a lower segment in direct contact with and reacting directly against the surface upon which the device is to be ridden, said annular spring having nearly constant flexural and stiffness properties throughout the entire annulus, wherein said device can be mounted by a rider and wherein the elasticity of said spring member is such that said rider, following an operating sequence in which energy is stored in the spring member by bending his legs to impose his weight thereon and releasing said energy to do work by straightening his legs can use the elasticity of said spring member to produce substantially vertically directed oscillations of said device and said rider.
