US 4,787,630 A · Exercise device

Abstract

An exercise device including rotatably interconnected base and platform assemblies. The base assembly is adapted to rock back and forth on a floor or other horizontal surface and a person using the device stands, sits, kneels or lays on the platform assembly. The device is adjustable whereby the permitted range of movement can be widely varied. Ropes, springs, elastic cords or poles can be grasped by a person using the device for balance and for upper body exercise.

Dependent claims

An exercise device, which comprises:

(a) a base assembly including a base plate with upper and lower surfaces;
(b) a platform assembly including a platform plate with upper and lower surfaces;
(c) a bearing connected to said base plate upper surface and said platform plate lower surface, said bearing being adapted to permit rotational movement about a rotational axis extending in a direction substantially normal to said base and platform plates and to maintain said base and platform plates in substantially parallel, spaced relation;
(d) stop means adapted for limiting the rotational movement of said platform assembly relative to said base assembly and comprising a stop lug mounted on said base plate upper surface and a stop pin projecting downwardly from said platform plate lower surface and adapted to engage said stop lug;
(e) said platform plate including a plurality of spaced stop pin receivers extending between its upper and lower surfaces and arranged in a circular pattern around said rotational axis;
and
(f) said stop pin comprising a shank adapted to be slidably and removably received in a respective stop pin receiver, a head and a pull tab received on said shank below said head and adapted to engage said platform plate upper surface.

9 more elements

An exercise device, which comprises:

(a) a base assembly including:
(1) a baseplate with opposite sides, opposite ends and upper and lower surfaces;
(2) a plurality of opposed pairs of rocker bar pin receivers in said baseplate and open at the lower surface thereof;
(3) a rocker bar including a convex, semicylindrical contact surface and a pair of upwardly-projecting rocker bar pins adapted for removable placement in said rocker bar pin receivers;
and
(4) a pair of stop lugs each mounted on and projecting upwardly from said baseplate upper surface and including a respective upwardly-open stop pin receive, each said stop lug being mounted adjacent a respective baseplate side;
(b) a platform assembly including:
(1) a platform plate with opposite sides, opposite ends, upper and lower surfaces and a downwardly-projecting thickened center portion;
(2) a plurality of stop pin receivers extending through said platform plate between its upper and lower surfaces, said stop pin receivers being positioned in a substantially circular pattern in spaced relation around said rotational axis;
(3) a pair of side loops each mounted on a respective platform plate side;
and
(4) a pair of end loops each mounted on a respective platform plate end;
(c) a pivot bolt receiver extending through the centers of said baseplate and said platform plate in alignment with said rotational axis, said pivot bolt receiver including a countersunk portion open at said platform plate upper surface;
(d) a pivot fastener including a pivot bolt rotatably received in said pivot bolt receiver and having a head received in the pivot bolt receiver countersunk portion and a nut threadably received on the pivot bolt below the baseplate lower surface;
(e) a bearing assembly centered on said rotational axis and including a lower half mounted on said baseplate upper surface, an upper half mounted on said platform plate lower surface below said platform plate thickened center portion and a plurality of ball bearings received between said bearing assembly halves;
(f) a pair of stop pins each including a shank, a head, a pull tab mounted on said shank below said head and a lower end, each said stop pin being adapted to be received in a respective stop pin receiver with said lower end thereof positioned in spaced relation above said baseplate upper surface;
(g) a pair of ropes each including a proximate end connected to a respective loop and a distal end;
and
(h) a pair of poles, each including:
(1) an inner section with a plurality of fastener receivers;
(2) a hollow outer section telescopically receiving said inner section and including an aligned pair of fastener receivers;
(3) a pair of tips each mounted on a respective section;
and
(4) a mechanical fastener extending through said outer section receivers and an aligned pair of inner section receivers.

Detailed description1,676 words

#As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

#For purposes of the description herein, the exercise device is oriented in FIG. 2 transversely from left to right and longitudinally from top to bottom.

#Referring to the drawings in more detail, the reference numeral 1 generally designates an exercise device embodying the present invention and including base and platform assemblies 2, 3. The base assembly 2 includes a baseplate 11 with opposite sides 12, opposite ends 13, an upper surface 14 and a lower surface 15. A semi-cylindrical rocker bar 18 is mounted on the baseplate lower surface 15 by a pair of rocker pins 19 inserted in an opposed pair of pin receivers 20 which extend upwardly into the baseplate 11 from its lower surface 15. A total of eight rocker bar pin receivers 20 are provided in a circular pattern on the baseplate 11 and are spaced in a circular pattern at about 45.degree. intervals whereby the rocker bar 18 can be oriented longitudinally, transversely or diagonally with respect to the baseplate 11. The orientation of the rocker bar 18 determines how the base assembly 2 will rock; e.g. side-to-side, end-to-end, or corner-to-corner. The rocker bar 18 includes a convex, semi-cylindrical contact surface 22 adapted to engage a floor 23 or other horizontal surface.
