DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Referring to FIG. 2, the physical exercise balancer comprises a main post 20 made up of a hollow lower beam 21 and upper beam 22, a plurality of stuffing sleeves 23, a handle 30, a pair of screws 31, a supporting mount 40, a stepping board 41, a pivot shaft 42, a leg base 50.

[0031] The hollow lower beam 21 and the upper beam 22 that can be made in a rectangular or circular section are telescopically associated with each other for adjustment. The lower beam 21 is provided with a number of equally spaced openings 211 on one inner wall of the lower portion thereof. On the outer surface of the lower beam 21 are disposed a plurality of equally spaced retaining holes with a screw hole disposed at the bottom end thereof. The upper beam 22 is provided with a plurality of equally spaced through holes 221 and 222 on both the opposite sides thereof with a proper distance defined between the through holes 221 and 222. There are a plurality of locking sleeves 23 having a threaded central through hole and. On the inner wall of the lower beam 21 are disposed a plurality of protrusion spots (not marked) with which the locking sleeves 23 can be selectively engaged for telescopic adjustment of the upper beam 21 according to a height of a user. The handle 30 having an axial through hole 301 for attachment to the top end of the upper beam 22 are provided with a lateral through hole 302 and 303 at the top and bottom end thereof for securing the handle 30 to the top end of the upper beam 22 by way of screws 31. The supporting mount 40 has a central hole 401 slightly larger than the outer dimension of the lower beam 21 and two pivot lugs 402 disposed at the front thereof and having a pivot hole thereon respectively. On the top surface of each pivot lug 402 is defined a retaining groove 404. Between the pivot lugs 402 is defined a dodge cavity 403 in communication with the interior of the supporting mount 40. The stepping board 41 has a plurality massage protrusion spots 411 on the top surface and a pivot joint 412 as well as a rectangular supporting block 413 which can engage with the lower edge of the opening 211 for supporting purpose. On the external face of each side of the pivot joint 412 is disposed a retaining projector 414. The stepping board 41 is pivotally mounted to the supporting mount 40 as a whole by way of the pivot shaft 42 which is led through the pivot lugs 402 of the supporting mount 40 and the pivot joint 412 and retained in place at the rear end thereof so as to permit the supporting mount 40 and the stepping board 41 pivotally joined together to be selectively engaged with one of the openings 211 of the lower beam 21. The leg base 50 having a slipper proof pad 51 is secured to the bottom of the lower beam 21 in assembly.

[0032] Referring to FIG. 4, note, in operation the supporting mount 4 is mounted to the lower beam 21 and in selective engagement with one of the openings 211 and the stepping board 41 is forced to pivot about the pivot shaft into a perpendicular position with respect to the lower beam 21. In the pivot operation, the supporting block 413 is first located at a distance of the lower edge of the opening 211 so that the stepping board 41 can be pivoted downwardly for use. Afterwards, the supporting mount 40 is forced to move down along the lower beam 21, making the supporting block 413 in abutment against the lower edge of the opening 211 for use, as shown in FIG. 5. To collect the pivoted stepping board 41, the supporting mount 40 is lifted up in a reverse manner on the lower beam 21 so as to permit the stepping board 41 to be pivoted into a vertical position with the retaining projectors 414 in retaining engagement with the retaining grooves 404 of the supporting mount 40 to hold the stepping board 41 in place for storage.

[0033] Referring to FIG. 6, the second embodiment is illustrated. Basically speaking, the second embodiment is similar to the first embodiment of the present invention, only the stepping board 41′ is placed on the side of the main post 20, i.e., a user is standing on the stepping board 41′ with the main post 20 located on his or her right hand side instead of the front side as shown in the first embodiment.

[0034] The difference in the first embodiment and the second embodiment lies in the supporting mounts 40 and 40′. As shown in FIG. 6, in the second embodiment, the supporting mount 40′ has a limiting block 413′ on the pivot joint 412′. On the pivot lugs 402′ are disposed countersunk holes 404′ for passage of the pivot shaft 42′. On the front face of the supporting mount 40′ are disposed a retaining hole 405′ and a positioning bore 406′. The retaining hole 405′ is designed for engagement with the limiting block 413′ of the supporting mount 40′ and the positioning bore 406′ is used for holding a V-shaped resilient retaining piece 43′ having an engagement head 431′ at the front thereof On the inner surface of the pivot lugs 402′ are disposed a retaining cavity 407′ respectively for holding the ends of the V-shaped resilient retaining piece 43′. The elements identical to those disclosed in the first embodiment are not repeatedly described and they are marked with the same numerals plus a prime mark.

[0035] As shown in FIG. 7, the stepping board 41′ is pivotally engaged with the supporting mount 40′ by way of the pivot shaft 42′.
