Abstract

A kit for assembly of exercise apparatus (1) comprising a first major component (2) and a second minor component (3) each with engagement means (22–25) complementary to those on the other and detachably interengagable with each other in alternative mutual orientation of those components (2, 3) so that the assemblage can be arranged and rearranged at will be assume alternative bench, chair or incline configurations.

Claims

1. Exercise apparatus in the form of a kit of parts, whether assembled or not, which comprises at least a first major component provided with engagement means in at least three alternative sites thereon, and a second minor component provided at a site thereon with engagement means complementary to those on the major component, said engagement means being detachably interengageable with one another in alternative mutual orientations of the components wherein:

the major and minor components are each substantially symmetrical about a shared, normally-vertical plane of symmetry, which in use also accommodates the user'"'"'s body axis;

in overall outline in said shared normally-vertical plane of symmetry that accommodates the user'"'"'s body axis, the major and minor component are each generally wedge-shaped, the opposed, wedge-forming sides thereof subtending the same angle θ

in each component; and

said complementary engagement means provided on said first major component and said second minor component are in the form of male and female members;

such that in use, the resultant assemblage can be arranged and rearranged at will to assume each of a range of alternative configurations comprising bench, chair and incline configurations.

2. Exercise apparatus as claimed in claim 1, in which the complementary engagement means on both the major component and the minor component are disposed and are mutually engageable and disengageable normal to said plane of symmetry in order to assume at least said bench and chair configuration.

3. Exercise apparatus as claimed in claim 1, in which in overall outline in the shared normally-vertical plane of symmetry that accommodates the user'"'"'s body-axis, the major component is a generally wedge-shaped irregular pentagon, having major and minor wedge-forming sides, and the minor component is a generally wedge-shaped irregular tetragon each of said components having two opposed non-parallel faces subtending the same angle θ

in each component and each having two other opposed generally-parallel faces, the pentagon having a fifth face intersecting with the minor wedge-forming face at one end thereof and with the major end-face at its other end, and being parallel to the major wedge-forming face, so that when assembled with the major end-faces of both components side-by-side in the same horizontal plane and with one of the wedge-forming faces of the tetragon in abutting facial contact with the fifth face of the pentagon then the assemblage is arranged so as to assume its chair configuration with the minor end face of the tetragon in an horizontal plane to serve as seat-portion of said chair and the minor wedge-forming face of the pentagon reclines therefrom to serve as back-portion of said chair.

4. Exercise apparatus as claimed in claim 3, in which the acute angle subtended by the wedge-forming opposed non-parallel faces of both the major and the minor components is θ

;

the acute angle α

between the major wedge-forming face of the manor component and a perpendicular from the major end-face thereof is equal to the acute angle α

between the first wedge-forming face of the minor component and a perpendicular from the major end-face thereof;

the acute angle β

between the minor wedge-forming face of the major component and a perpendicular from the major end-face thereof is equal to the acute angle β

between the second wedge-forming face of the minor component and a perpendicular from the major end-face thereof; and

in which α

+β

=θ

;

while the back-portion of said chair reclines at an acute angle from the vertical, which is equal to β

.

5. Exercise apparatus as claimed in claim 3, in which the major component is further provided with a cut-out section in the corner thereof between its major end-face and the fifth face thereof, which cut-out section comprises an internal face intersecting the fifth face being parallel to the major end-face of the major component, and an internal face intersecting said major end-face being parallel with the major wedge-forming face of said major component;

the dimensions of the cut-out being complementary with those of the minor component, such that when the minor end of the minor component is mated therewith, one of its wedge-forming faces is co-planar with the minor wedge-forming face of the major component, so that when thus assembled the resultant assemblage assumes its incline configuration.

6. Exercise apparatus as claimed in claim 5, in which the major component is provided with side-pods to either side of the cut-out section, said side-pods comprising a side parallel to and co-planar with the fifth face of the pentagon, and a side parallel to and co-planar with the major end-face of the major component, said side-pods being displaced outwards from the plane of the pentagon so as to constitute extensions of the fifth side thereof and the major end-face, but allowing access to the complementary internal faces within said cut-out.

7. Exercise apparatus as claimed in claim 5, in which the at least three sites on the major component at which there are provided engagement means comprise:

a site located in the minor wedge-forming face, disposed substantially towards the minor end thereof, which site accommodates the engagement means of the minor component so as to form the bench configuration;

a site located in the fifth face of the pentagon, which site accommodates the engagement means of the minor component so as to form the chair configuration; and

a site located within the cut-out section, in the internal face intersecting the major end-face, being parallel with the major wedge-forming face, which site accommodates the engagement means of the minor component so as to form the incline configuration.

8. Exercise apparatus as claimed in claim 1, in which said first major component is provided with female members only and said second minor component is provided with male member(s) only.

9. Exercise apparatus as claimed in claim 1, in which the wedge-subtending angle θ

is in the range of from 20°

to 35°

.

10. Exercise apparatus as claimed in claim 9, in which the wedge-subtending angle θ

is substantially equal to 26°

.

11. Exercise apparatus as claimed in claim 4 in which the angles α

and β

are substantially equal.

12. Exercise apparatus as claimed in claim 1, in which the male member(s) are in the form of (an) upstanding ridge(s) and the complementary female member(s) are in the form of groove(s), each extending substantially across the width of the respective component face.

13. Exercise apparatus as claimed in claim 12, in which the male member(s) and the complementary female member(s) are of generally cylindrical, polygonal or omega-shaped cross-section.

14. Exercise apparatus as claimed in claim 12, in which the set of male members comprises a pair of ridges and the first and second sets of female members each comprise a pair of grooves.

15. An exercise apparatus as claimed in claim 14, in which each pair of ridges and each pair of grooves comprises members of different size, so that the minor component may only enter into engagement with the major component in one specific orientation at each site on the major component at which the female members are located.

16. Exercise apparatus as claimed in claim 1 in which the major component and/or the minor component are provided with channels adapted to receive elastic resistance bands therein.

17. Exercise apparatus as claimed in claim 1, in which the major component and/or the minor component are provided with cut-out sections therein to act as hand-grips during use of the apparatus.

18. Exercise apparatus as claimed in claim 1, in which the major and minor components are formed substantially from injection moulded plastics material.

19. Exercise apparatus as claimed in claim 3, in which the major wedge-forming face of the major component is in the form of a detachable platform;

and

there are further provided mounting blocks on which said detachable platform may be mounted, so as to form a so-called ‘

step’

aerobics exercise platform.
