Abstract

Abstract An exercise device of the flexible bed type having a rigid frame and a bed formed of flexible fabric which is yielding supported on the frame in a tightly stretched condition. The bed is supported by yieldable elements connecting the marginal portion of the bed to the sides of the frame and which are arranged to provide a maximum of tension in a central region of the bed to allow the user to perform a bouncing action on the bed with a minimum of flexing of the bed. This is provided by coil springs which are connected so that the springs to the right of the center of the frame are connected to the frame at a point to the right of an imaginary line perpendicular to the frame through the point where the spring is connected to the bed and the springs to the left of center of the fraame are connected to the frame at a point to the left of an imaginary line perpendicular to the frame through a point where the spring is connected to the bed. The apparatus may be supported on legs which are removable for convenience in transportation and storage or may be supported on an enclosing frame to enable the device to be used as an article of furniture when not being used for exercising.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 175 words
Exercising apparatus comprising: a rectangular frame, said frame formed of opposite side frame portions and opposite end frame portions, a rectangular bed formed of flexible fabric disposed in said frame having side margins and end margins spaced inwardly from the side frame and end frame portions, respectively, means for supporting said frame in a substantially horizontal plane, and coil springs connected at their inner ends to be margins of said bed and connected at their outer ends to said frame, all said springs being connected so that the springs to the right of the center of said side and end frame are connected to said frame at a point to the right of an imagnary line perpendicular to said frame through the point where the spring is connected to said bed and the springs to the left of center of said side and end frame are connected to said frame at a point to the left of an imaginary line perpendicular to said frame through a point where the spring is connected to said bed.
Claim 2
Dependent Claim 175 words
Exercising apparatus comprising: a rectangular frame, said frame formed of opposite side frame portions and opposite end frame portions, a rectangular bed formed of flexible fabric disposed in said frame having side margins and end margins spaced inwardly from the side frame and end frame portions, respectively, means for supporting said frame in a substantially horizontal plane, and coil springs connected at their inner ends to be margins of said bed and connected at their outer ends to said frame, all said springs being connected so that the springs to the right of the center of said side and end frame are connected to said frame at a point to the right of an imagnary line perpendicular to said frame through the point where the spring is connected to said bed and the springs to the left of center of said side and end frame are connected to said frame at a point to the left of an imaginary line perpendicular to said frame through a point where the spring is connected to said bed.
Claim 3
Dependent Claim 14 words
An apparatus according to claim 1 wherein said coil springs are of equal size.
Claim 4
Dependent Claim 31 words
An apparatus according to claim 1 wherein an equal number of springs are connected to the right of center of said side and end frame as to the left of center.
Claim 5
Dependent Claim 51 words
An apparatus according to claim 1 wherein at each corner of said bed one of said coil springs is connected at its inner end to said corner of said bed and is connected at its outer end to said frame at a location spaced from the adjacent corner of said frame.
Claim 6
Dependent Claim 50 words
An apparatus according to claim 1 wherein two of said coil springs are located centrally of the length of each side of the bed and are connected to the adjacent side of said frame at points spaced apart at a greater distance than the points of connection to said bed.
Claim 7
Dependent Claim 30 words
An apparatus according to claim 5 wherein the springs are connected to said bed and frame along each side thereof from the two centrally located springs at increasingly greater distances.
