Abstract
Abstract A surfing simulator consists of a top board which is suspended by a spring suspension system consisting of two units. In one embodiment, each unit includes two spaced apart parallel coil springs. The units are used to suspend the top board above an appropriate surface, e.g., ground. The rockability of the top board about one axis when a person steps on the board, is dependent on the orientations of the springs with this axis. The rockability of the board about a transverse axis depends on the spacing between the two units. Both the orientations of the springs and the spacing between the units is easily variable.

A surfing simulator comprising: an elongated board having top and bottom sides and defining a longitudinal axis in a plane parallel to said sides; spring suspension means including first and second spring assemblies, each assembly including at least one coil spring and top and bottom members with the spring connected therebetween, with the spring axis extending between said members; and connecting means for selectively connecting each assembly to the board by securing the assembly top member to the board''s bottom side with the spring''s axis perpendicular to said longitiduinal axis, whereby said springs suspend said board above a support surface with which the bottom members of said assemblies are in contact, with the rockability of said board about an axis perpendicular to said longitudinal axis being a function of the spacing between said assemblies, each of said assemblies includes first and second coil springs spaced apart and parallel between the top and bottom members of the assembly, each assembly defines a plane in which the axes of the springs of the assembly lie, and said connecting means connect each assembly to said board at a selectable angular orientation of the assembly''s plane with respect to the board''s longitudinal axis so as to control the rockability of the board about said longitudinal axis, the top member of each assembly defining an aperture equidistant from the two springs of the assembly, said board defining a plurality of apertures along its longitudinal axis, and said connecting means include a pair of bolts, extending through one of said board apertures and the aperture of the top member of one assembly, with the rockability of the board about an axis perpendicular to its longitudinal axis being a function of the distance between the board''s apertures through which the bolts extend.

A surfinG simulator comprising: an elongated board having top and bottom sides and defining a longitudinal axis in a plane parallel to said sides; first and second identical spring assemblies, each assembly including a pair of similar coil springs, top and bottom members and means for securing said springs between said members, with the springs being spaced from one another and with the axis of each spring extending between said members, the axes of the two springs being an imaginary plane extending through said assembly; and connecting means for connecting said assemblies to the bottom side of said board so as to suspend said board above said assemblies with each assembly being connected at a variable selected angular orientation of its plane with respect to said longitudinal axis, each assembly being connected to said board so that its springs are at equal distances from said longitudinal axis, with the planes of said assemblies being vertically oriented and said longitudinal axis is in a horizontal plane and the angular orientation of each assembly plane with respect to said longitudinal axis being variable between zero and ninety degrees, said board defining a plurality of apertures along said longitudinal axis, each aperture extending between the board''s top and bottom sides, and said connecting means include means for each assembly which extend through a selected one of said apertures to connect the assembly to the board through the selected aperture to thereby vary the spacing between the assemblies connected to said board.
