Abstract:
A moveable surface exercise device comprising:a frame, including a pair of substantially longitudinal side frames;a continuous segmented track, including:a plurality of individual deck members movably connected one to another, thereby creating a continuous loop being disposed so as to enable an upper run and a lower run;a plurality of support members mounted to said deck members, at least two support members being received by said frame;a plurality of permanent magnets secured to said deck members, the permanent magnets generating a magnetic field;at least one coil means mounted to said frame, the at least one coil means capable of generating an electromagnetic field, the magnetic field from said permanent magnets passing through the electromagnetic field, thereby applying force to said continuous loop; anda controller means to vary the electromagnetic field strength of said at least one coil means, thus enabling variation in the speed of movement of said continuous loop relative to said at least one coil means, whereby said upper run is a continuous surface capable of moving and supporting a load placed on said deck members, the load being transmitted through said support members to said frame.
