DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0016] With reference to FIGS. 1 and 2, an exerciser in accordance with the present invention comprises a stand (20), a base (30) and two covers (10,101). The stand (20) comprises a supporting rod (28), a knob (21), a stand rod (25) and a positioning plate (24). The supporting rod (28) has a threaded hole (281) defined in the middle portion of the supporting rod (28). A through hole (282) with a diameter smaller than that of the threaded hole (281) is defined in a bottom of the threaded hole (281), such that a shoulder (not numbered) is formed between the threaded hole (281) and the through hole (282). Multiple cavities (284) are defined in the supporting rod (28). A groove (283) is defined around each respective end of the supporting rod (28).

[0017] The knob (21) is detachably attached to the supporting rod (28). A stub (22) extends downward from the knob (21) and has an outer thread (not numbered) to screw with the threaded hole (281) in the supporting rod (28). A curve cavity (23) is defined in the bottom of the stub (28), and a tab (211) is formed on the top of the knob (21) for the user to conveniently rotate the knob (21).

[0018] The stand rod (25) is rotatably mounted between the supporting rod (28) and the knob (21). The stand rod (25) has a rod body (27) extending through the through hole (282) of the supporting rod (28). A ball (26) is formed on the top of the rod body (27) and is rotatably received between the shoulder in the supporting rod (28) and the curve cavity (23) in the knob (21). A neck (261) with a diameter smaller than that of the rod body (27) is formed between the ball (26) and the rod body (27). In addition, multiple longitudinal channels (271) are defined in the outer periphery of the rod body (27) along an axial direction of the rod body (27). In practice, each channel (271) extends to the bottom of the rod body (27).

[0019] The positioning plate (24) is rotatably mounted around the stub (22) on the knob (21) and abuts with the bottom of the knob (21). A through hole (242) is defined in the positioning plate (24) for the stub (22) extending through the through hole (242). Two curve edges (240) are formed on opposite sides of the positioning plate (24), and two flat edges (241) are formed on opposite sides of the positioning plate (24). Two protrusions (243) are formed on the bottom of the positioning plate (24).

[0020] The base (30) is detachably attached to the bottom of the stand (20) to support the stand (20). The base (30) has four legs (31) attached to the rod body (27) of the stand rod (25). A T-shaped rail (33) is formed on one end of each respective leg (31) to engage with one of the channels (271) in the rod body (27). A supporting bar (35) with a U-shaped cross section is pivotally attached to each respective leg (31). An inverse U-shaped recess (311) is defined in the top of each respective leg (31) to receive the corresponding one of the supporting rods (35). Two pivotal holes (32) are respectively defined in two sides of each respective leg (31). Two pivots (351) extend from the inner surface of each respective supporting bar (35) and are respectively inserted into the pivotal holes (32) in the corresponding one of the legs (31) to make the supporting bar (35) be pivotally attached to the corresponding leg (31).

[0021] The covers (10,101) are rotatably attached to the supporting rod (28) of the stand (20). Each respective cover (10,101) has a skirt (11) extending around the bottom of the cover (10,101) so as to define a chamber (12) in the bottom of the cover (10,101). Multiple baffles (not numbered) are formed on the inner surface of the chamber (12) of each respective cover (10,101). The elements of the stand (20) and the base (30) can be securely received in the chambers (12) and held on the baffles of the cover (10,101) after the stand (20) and the base (30) being disassembled as shown in FIG. 4. A holding tab (17) with a curve recess (not numbered) is formed on each respective cover (10,101) and corresponds to one of the grooves (283) in the supporting rod (28). A recess (14) with a curved inner edge is defined in one side of the top of each respective cover (10,101). A depression (15) is defined in the bottom of recess (14) in each respective cover (10,101). Multiple bumps (13) are formed on the top of each respective cover (10,101). Two lock holes (16) are defined in each respective cover (10,101).

[0022] In assembling, the rod body (27) of the stand rod (25) penetrates through the through hole (282) in the supporting rod (28), and the ball (26) of the stand rod (25) is supported on the shoulder in the supporting rod (28). The covers (10,101) are attached on the supporting rod (28) respectively at two sides of the threaded hole (281), and the holding tabs (17) are respectively engaged with the grooves (283) in the supporting rod (28). A U-shaped rod holder (29) encloses each side of the supporting rod (28) and has two ears (291) respectively engaging with the lock holes (16) in the corresponding one of the covers (10,101). Consequently, the covers (10,101) will be rotatably attached to the supporting rod (28) with the rod holders (29). The stub (22) on the knob (21) then extends through the through hole (242) in the positioning plate (24) and is screwed into the threaded hole (281) in the supporting rod (28). The legs (31) are attached to channels (271) in the rod body (27) with the rails (33), such that the stand (20) with the covers (10,101) can be put on a flat object with the base (30).

[0023] In a first operational embodiment, with reference to FIGS. 1, 2 and 5, the knob (21) is slightly released from the threaded hole (281) in the supporting rod (28). The positioning plate (24) is rotated relative to the stub (22) of the knob (21) to a position where the curve edges (240) of the positioning plate (24) are respectively received in the recesses (14) in the covers (10,101). The protrusions (243) on the positioning plate (24) will be respectively inserted into the depressions (15) in the covers (10,101). After the knob (21) is screwed onto the positioning rod (28) to a tightened condition, the covers (10,101) are squeezed between the supporting rod (28) and the positioning plate (24) and are connected to each other through the positioning plate (24). Two supporting bars (35) corresponding to the supporting rod (28) are pivotally rotated relative to the corresponding legs (31) and respectively abut two cavities (284) on the supporting rod (28) with the free ends. Consequently, the user can step on the covers (10,101), and the user can pivotal rotate ankles in two directions with the supporting rod (28) as an axle as shown in FIG. 5. The ankles of the user can be exercised with the exerciser. In addition, the bumps (13) on the covers (10,101) provide a massage effect to the feet of the user.

[0024] In a second operational embodiment, with reference to FIGS. 2 and 6, the knob (21) is slightly released from the threaded hole (281) in the supporting rod (28). The positioning plate (24) is rotated relative to the stub (22) to a position where the flat edges (241) of the positioning plate (24) are parallel to the sides of the covers (10,101) and the curve edges (240) are released from the recesses (14). This can release the connection between the two covers (10,101). Consequently, the covers (10,101) can pivotally rotate relative to the supporting rod (28) in different directions respectively. Accordingly, the exerciser can be used as a stepping exerciser when the user steps on the covers (10,101).

[0025] With reference to FIG. 7, the supporting bars (35) on the legs (31) are rotated to a position where they abut the corresponding legs (31) and leave the supporting rod (28), so as to release the supporting effect provided by the supporting bar (35) from the supporting rod (28). Consequently, the supporting rod (28) can universally rotate relative to the stand rod (25) at the ball (26) as a center, such that the covers (10,101) with the supporting rod (28) can be rotated in a universal direction relative to the stand rod (25). This can make the user rotate ankles in a universal direction.

[0026] With such an exerciser in accordance with the present invention, multiple exercising and training effects are provided, the use of the exerciser is versatile.

[0027] After unscrewing the knob (21) from the threaded hole (281) in the supporting rod (28), the positioning plate (24) can be taken away from the supporting rod (28). The rails (33) on legs (31) are released from the channels (271) in the stand rod, and the stand rod (25) can be taken out from the through hole (282) in the supporting rod (28). To disengage the ears (291) on the rod holders (29) from the lock holes (16) in the covers (10,101), the covers (10,101) can be released from the supporting rod (28). Consequently, the exerciser is detached into multiple separate elements. The elements of the stand (20) and the base (30) can be put into the chambers (12) in the covers (10,101) and be held by the baffles in the chambers (12) as shown in FIG. 4. To combine the covers (10,101) with studs (not numbered) and holes (not numbered) formed on the covers (10,101), the covers (10,101) can combine with each other to receive the stand (20) and base (30). Accordingly, with reference to FIG. 8, the user can easily carry the exerciser to anywhere. The exerciser can be also put into the pocket of clothes or pants for transporting it, such that the exerciser is portable and the use of the exerciser is convenient.

[0028] Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
