Abstract

A step bench for performing repetitive stairstep exercises has adjustable-height support members and a retractable floor mat. The adjustable-height support members are configured as telescoping cylinders, with vertically extending stair-like slots formed in the wall of one of the cylinders, and corresponding pegs attached to the adjacent wall of the other cylinder to extend slidably through the slots. The height of the support members is adjusted by rotating the cylinders relative to each other to move the pegs from one "stair" of the slot to an upper or lower "stair". A retractable floor mat assembly comprises a roller mounted beneath the bench platform to left and right flanges depending from the ends of the platform, with a mat wound about the roller in a manner similar to a windowshade.

Claims

1. A step bench for performing stair-step exercises, said step bench comprising:

a platform having a top surface for stepping on by a user and an underside surface;

a plurality of support members attached to said lower surface sufficient to stably support said step bench on a support surface, each of said plurality of support members having a pair of members moveable relative to each other axially and rotationally, said pair of members having means associated therewith to adjust their relative axial relationship and in turn the overall length of the respective support member;

a roller having first and second ends both disposed below and secured to said platform; and

a mat having a fixed end attached to said roller, said mat being rotatably wrappable about said roller and said mat having a free end which may be gripped and pulled by a user to unroll the mat from said roller a preselected distance on a support surface.

2. The step bench of claim 1, wherein each said support member is formed of a first cylindrical member telescopingly associated with a second cylindrical member.

3. The step bench of claim 2, wherein:

said first cylindrical member has at least two substantially ascending slots formed therein, each of said slots comprising a plurality of generally upright segments alternating with transverse segments; and

said second cylindrical surface has a plurality of pegs extending therefrom and corresponding in number to said slots, said pegs being snugly and slidably positioned in said slots.

4. The step bench of claim 3, wherein said platform is generally rectilinear in projection.

5. The step bench of claim 3, wherein said second cylindrical surface is an outer surface of an inner cylinder and said first cylindrical surface is an inner surface of an outer cylinder slidably disposed about said inner cylinder.

6. The step bench of claim 5, wherein said outer cylinder has an upper end which is attached to said underside of said platform, and said inner cylinder has a lower end for positioning on a support surface.

7. The step bench of claim 6, further including a base for positioning on a support surface at said lower end of said inner cylinder.

8. The step bench of claim 7, wherein said base has means for grasping by a user to rotate said inner cylinder relative to said outer cylinder.

9. The step bench of claim 6, wherein said inner cylinder has an upper end which is attached to said underside of said platform, and said outer cylinder has a lower end which rests on a floor.

10. The step bench of claim 3, wherein said first cylindrical surface is an outer surface of an inner cylinder and said second cylindrical surface is an inner surface of an outer cylinder slidably disposed about said inner cylinder.

11. The bench of claim 10, wherein said inner cylinder has an upper end which is attached to said underside of said platform, and said outer cylinder has a lower end which rests on a floor.

12. The step bench of claim 10, wherein said outer cylinder has an upper end which is attached to said underside of said platform, and said inner cylinder has a lower end for positioning on a support surface.

13. The step bench of claim 1, wherein said platform has two opposite ends and first and second flanges depending from said opposing ends;

and wherein said roller is rotatably mounted at said first and second ends to said first and second flanges, respectively.

14. The step bench of claim 13, wherein said first end of said roller extends slidably through said first flange, and wherein a handle is adapted to said first end for operation by the user to rotate said roller for retracting or unrolling said mat.

15. An adjustable height bench for repetitive stepping upon by a user performing step exercises, said adjustable height bench comprising:

a platform having opposing ends, a top surface extending therebetween for stepping on by a user, and an underside surface;

at least one pair of support members attached to said lower surface at opposing ends of said platform, each of said support members comprising;

an inner cylindrical member having an outer surface and one or more protrusions extending outward from said outer surface, and

an outer cylindrical member slidably annularly disposed about said inner cylindrical member, and having one or more slots each comprising at least one horizontal segment contiguous with a downwardly extending segment;

a roller rotatably mounted below said platform between said opposing ends; and

a flexible mat having a fixed end attached to said roller, said flexible mat being wrapped around said roller, and said flexible mat having a free end which may be gripped and pulled by a user to unroll the mat from said roller.

16. The bench of claim 15, wherein said outer cylindrical member is attached to said underside surface and said inner cylindrical member has a lower end which contacts a support surface.

17. The bench of claim 16, wherein said lower end has means associated therewith for gripping by the user to rotate said inner cylindrical member within said outer cylindrical member.

18. The bench of claim 17, having two pairs of said support members respectively attached at the four corners of said platform.

19. The bench of claim 18, wherein said slots each comprise at least one rotational upper segment and one rotational lower segment connected by a first axial segment.

20. The bench of claim 15, wherein said roller has first and second ends, and further including a knob adapted to said first end for rotating said roller to retract or unroll said mat.

21. A combination step bench and floor mat for use in exercise sessions including repetitive stairstep exercises, consisting essentially of:

a single platform having opposing ends, a top surface extending therebetween for stepping on by a user, and an underside surface;

first and second flanges depending from said platform, said first flange disposed proximal to one of said opposing ends and said second flange disposed proximal to the other of said opposing ends;

support members attached to said lower surface at said opposing ends of said platform, said support members being operable to vary the height of said top surface above a support surface;

a roller having first and second ends, said roller being disposed below said platform and rotatably mounted at said first and second ends to said first and second flanges, respectively; and

a flexible mat having a fixed end attached to said roller, said flexible mat being wrapped around said roller, and said flexible mat having a free end which may be gripped and pulled by a user to unroll the mat from said roller.

22. The bench of claim 21, wherein said first end of said roller extends slidably through said first flange, and further including a knob adapted to said first end for rotating said roller to retract or unroll said mat.

23. The bench of claim 22, wherein said second end of said roller is releasably mounted in a bushing, said bushing being attached to said second flange.
