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.
