6~7 memhers and adapted to serve as handle means for the rider.
The device of -the present invention inc]ucles a pair oE string-like members, each being disposed secured to the under-side of the suspension member, depending downwardly therefrom and shaped arcuately so as to have the free ends thereof engage the surface of the ground and provide an upward force when -the support member is directed downwardly to the ground thereby causing the rocker to easily and con~eniently spring back and continue in oscillations. The pair of second upright members are modified such that the first of the pair of members is fixedly secured to the suspension member and the other of the pair of second upright members being disposed removably in any of three holes located in the suspension member. This permits the other of the second upright members to be adjusted selectively along the length of the suspension member so as to enable the entire apparatus to be adjusted to accommodate for variations in the weight of a pair of users. The alternate embodiment also includes a pair of horizontally disposed support members installed trans-verse the hemi-arclllar shape base support members, such addi-tional pair of horizontally disposed support members beinginstalled approxlmately midway between the point of con-tact of the hemi-arcular shape base support members where contacting the ground,~and the location of the suspension member.

The member 10 is adapted to rock forward or backward along the outer surface of the member 10 as the same contacts the floor 14. The two members 10 are in coaxial alignment with each other.
Each member 10 will have a transverse rod or shaft mem-ber 18 disposed across the same at about 1/3 - 1/2 of the way upward from the point of contact 12; the foregoing adapted to serve as a safety bar or the like in order to give stability to the apparatus. The shaft member 18 is preferably permanently affixed by its distal end portions to the opposite sides of the rnember 10, such as by welding, rivets~ etc. or any other suitable fastening or affixation means 20. The member 18 also may func-tion as a point of contact for the feet 22 of the rider 24 if .:

6~7 member 30 that has a horizontal cross bar 32 thereon for han~le means. I~ desired, the beam 26 may define a pair of opposing notched areas 34 disposed between each pair of upriyhts 28, 30, for accommodation of the thighs of the rider 24.
~ dditional stability can be imparted to the device by having a second beam 36 disposed beneath the first beam 26, in contact therewith, in planar alignment, but extending only edge to edge across the member 10, whereas, the first beam 26, extends beyond the member 10 across both end ~ections.
The entire assembly may be constructed of any suitably rigid material such as high impact plastic, metal and wood.
An additional pair of holes 38 and 40, facilitating horizontal bar 32 being permitted to be moved inwardly at two locations towards the center of support member 26. This is accomplished by permitting upright member 30 to be installed into holes 38 and 40, selectively. The other horizontal cross bar 32 i5 locke~d in its location, because the equivalent of holes 38 and 4Q are not provided on that side of support member 26.
Spring members 42 and 44 are shown secured underneath support member 26, and as illustrated, extend outwardly therefrom so as to engage the surface of the ground, not shown, as support member 26 is pivoted above the plane of the ground. Figure 4 also illustrates transverse members 46, extending parallel to an under surface of support member 26 and engaging the downwardly directed portions of U-shaped support members 10. Members 46 are shown removahly affixed to member 10, thus lowering the cost of manufacturi~g and the weight of the entire apparatus.
