Abstract

An exerciser adapted for use in simulating skiing and the like including a base and a turntable rotatably mounted on the base. Thus, foot supports are mounted on the turntable so as to be rotatable therewith. The foot supports are movable with respect to the turntable and with respect to one another upon application of a predetermined amount of foot pressure so as to permit canting thereof in two opposing directions and pivoting in a third direction thereby permitting the user to selectively shift feet, legs, and body when engaged with the foot supports in any one of four directions of movement depending on the application of pressure thereto and accordingly exercising the users legs and body in a desired manner.

2. The invention in accordance with claim 1 wherein there is a separate cylindrical member, a separate heel support, and a separate pair of toe supports for each foot support.

3. The invention in accordance with claim 1 wherein the heel and tow supports are formed of rubber material adhesively bonded to the turntable.

4. An exerciser comprising:

a base, a turntable rotatably mounted on the base, foot support means on the turntable so as to be rotatable therewith, the foot support means being moveable with respect to the turntable upon application of a predetermined amount of foot pressure so as to permit canting thereof in two opposing directions and pivoting in a third direction thereby permitting the user to selectively move his feet when engaged with the foot support means in any one or in a combination of four directions of movement depending on the application of leg and foot pressure thereto and accordingly allowing the user to exercise in a desired manner, the canting movement being about a longitudinal axis of the foot support means corresponding to a longitudinal axis of a user'"'"'s foot positioned on the foot support means so as to permit shifting of the relative elevation of the inside and outside edges of the foot and the pivoting movement being about a transverse axis of the foot support means corresponding to a transverse axis of a user'"'"'s foot positioned on the foot support means so as to permit shifting of the relative elevation of the heel portion and toe portion of the user, the foot support means includes a pair of spaced foot supports to selectively support the feet of a user, each foot support adapted to be independently canted and pivoted with respect to the other foot support and the turntable, the foot support means is provided for facilitating canting of each support and includes a fulcrum member mounted on the turntable and engaging a receiving surface on the under surface of the foot support adjacent the portion of the foot support where the toe and ball portions of the foot of the user engages the foot support.

5. The invention in accordance in claim 4 wherein a bearing assembly is mounted between the base and the turntable to permit 360°

relative rotation therebetween.

6. The invention in accordance with claim 5 wherein the bearing assembly includes a first plate affixed to the base, a second plate affixed to the turntable in position to mate with the first plate, a race formed by surfaces on the mating plates, a plurality of ball bearings captured in the race and forming the engaging surface upon which the turntable can rotate with respect to the base.

7. The invention in accordance with claim 4 wherein the surface of each foot support adapted to be engaged by the user includes a frictional surface to deter relative movement therebetween, a side wall portion and toe wall portion extending toward from the foot engagment surface to facilitate retention of foot position relative to the foot support as the user moves his foot and the foot support relative to the turntable and the base in selected directions.

8. The invention in accordance with claim 7 wherein each side wall portion is an L-bracket with one leg fastened to the upper surface of a foot support and the other leg substantially aligned with at least a portion of the edge of the foot support distal from the other foot support and extending upwardly from the upper surface of the foot support.

9. The invention in accordance with claim 7 wherein each toe wall portion includes an L-bracket formed of three segments in the form of a shorter central segment and two longer end segments extending angularly from the ends of the central segments so that the toe wall portion generally conforms to the shape of the toe portion of the user'"'"'s shoe, one leg of each toe wall portion L-bracket fastened to the upper surface of a foot support and the other leg being substantially aligned with the adjacent edge of the foot support and extending upwardly therefrom.

10. The invention in accordance with claim 7 wherein the friction surface includes a ribbed pad affixed to a substantial portion of the upper surface of each foot support.

11. The invention in accordance with claim 4 wherein sensing means is positioned so as to monitor the degree of movement of the foot support means as the user moves the foot support means relative to the base.

12. The invention in accordance with claim 11 wherein display means in responsive to the sensing means to indicate the type and degree of sensed movement of the foot support means as the user operates the exerciser.

13. The invention in accordance with claim 12 wherein the sensing means includes at least one electrical sensor switch and the display means includes an electrical display board, and the switches and display board interconnected at a releasable electrical interface.

14. The invention in accordance with claim 13 wherein the foot support means includes a pair of spaced foot supports to respectively support the feet of a user, there is a first sensor switch located adjacent the heel portion of each foot support, a second sensor switch adjacent one side edge of each foot support, and a third sensor switch adjacent the other side edge of each foot support so as to be engaged and activated as each foot support is pivoted and canted from one side to the other respectively, and a rotation sensor switch positioned to sense the degree of rotation of the turntable and accordingly the foot supports rotating therewith as the user operates the exerciser.

15. The invention in accordance with claim 4 wherein the fulcrum member is cylindrical in configration and the heel portion of each foot support is at a higher elevation than the toe portion of each foot support in the relaxed condition, and a toe wall portion extending up from each foot support in position to be engaged by the toe portion of the foot of the user to facilitate retention of foot position relative to the foot support during use of the exerciser.

16. An Exerciser comprising;

a base, a turntable rotatably mounted on the base, foot support means on the turntable so as to be rotatable therewith, the foot support means being movable with respect to the turntable upon application of a predetermined amount of foot pressure so as to permit canting thereof in two opposing directions and pivoting in a third direction thereby permitting the user to selectively move his feet when engaged with the foot support means in any one or in a combination of four directions of movement depending on the application of leg and foot pressure thereto and accordingly allowing the user to exercise in a desired manner, the canting movement being about a longitudinal axis of a user'"'"'s foot positioned on the foot support means so as to permit shifting the relative elevation of the inside and outside edges of the foot and the pivoting movement being about a transverse axis of the foot support means corresponding to a transverse axis of a user'"'"'s foot positioned on the foot support means so as to permit shifting of the relative elevation of the heel portion and toe portion of the user, the foot support means includes a pair of spaced foot supports to selectively support the feet of a user, each foot support adapted to be independently canted and pivoted with respect to the other foot support and the turntable, a resilient heel extends upward from the turntable into engagment with the underside of the foot support at the location where the heel of the user engages the foot support and at least one resilient toe support extending up from the turntable into engagement with the portion of the foot support engaged by the toes of the foot of a user, and the foot support being mounted with the heel and toe portions thereof at different elevations whereby pivoting about a transverse axis will permit shifting of the relative elevations of the heel and toe portion of the foot support and this movement being accommodated by the resilient supports.
