Description
- 1. Field of the Invention
- The invention relates to an inversion exerciser, more particularly to an inversion exerciser including a foot retaining part pivoted to a beam and adjustable at an angle relative to the beam.
- 2. Description of the Related Art
- U.S. Pat. No. 7,081,073 discloses an inversion exerciser that includes: a beam provided with a pair of pivot boards; a curved rack secured to the pivot boards and provided with retaining teeth; a foot retaining part pivoted to the pivot boards; a block secured to a chamber in the foot retaining part, defining a passage and provided with a pawl; a rod slidably received in the passage and having one end pivoted to the pawl so as to rotate the pawl to disengage the retaining teeth of the rack; a spring for biasing the rod to rotate the pawl and to disengage the pawl from the retaining teeth of the rack; an elbow pivoted to the beam and having one end pivoted to the other end of the rod; and an operating post mounted slidably in the chamber in the foot retaining part and connected to the other end of the elbow for rotating the elbow against the spring in order to force the pawl to engage the retaining teeth of the rack. The inversion exerciser thus formed allows the root retaining part to be adjustable at an angle relative to the beam. However, the aforesaid conventional inversion exerciser is disadvantageous in that the structure of the parts required to permit engagement and disengagement between the retaining teeth and the pawl is complicated.
- Therefore, the object of the present invention is to provide an inversion exerciser that can overcome the aforesaid drawback associated with the prior art.
- Accordingly, an inversion exerciser of the present invention comprises: a beam having a pivot part that is formed with a plurality of retaining grooves which are angularly displaced along an arcuate track; a foot retaining part pivoted to the pivot part so as to be rotatable relative to the beam about a first axis; a swingable part having first and second end portions and a middle portion extending between the first and second end portions and pivoted to the foot retaining part so as to permit rotation of the swingable part relative to the foot retaining part about a second axis parallel to the first axis and so as to permit co-rotation of the swingable part and the foot retaining part about the first axis; a locking pin extending transversely relative to the swingable part and secured to the first end portion of the swingable part so as to be co-rotatable with the swingable part to thereby engage and disengage a selected one of the retaining grooves; an urging member for biasing the swingable part to rotate in a first rotation direction to retain the locking pin in the selected one of the retaining grooves; and a releasing member mounted movably on the foot retaining part and connected to the second end portion of the swingable part for rotating the swingable part in a second rotation direction opposite to the first rotation direction so as to disengage the locking pin from the selected one of the retaining grooves.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
-
FIG. 1 is an exploded perspective view of the preferred embodiment of an inversion exerciser according to the present invention; -
FIG. 2 is an assembled perspective view of the preferred embodiment; -
FIG. 3 is a fragmentary partly sectional view of the preferred embodiment, illustrating a state where a first locking pin is urged to be retained in a retaining groove; -
FIG. 4 is a fragmentary partly sectional view of the preferred embodiment, illustrating another state where the first locking pin is disengaged from the retaining groove; and -
FIG. 5 is a fragmentary partly sectional view of the preferred embodiment, illustrating yet another state where the entire exerciser is inverted and where a second locking pin engages a retaining groove. - Referring to
FIGS. 1 , 2 and 3, the preferred embodiment of an inversion exerciser according to the present invention is shown to include: abeam 2 having apivot part 22 that is formed with a plurality of retaininggrooves 231 which are angularly displaced along anarcuate track 23; afoot retaining part 3 pivoted to thepivot part 22 so as to be rotatable relative to thebeam 2 about a first axis (A) ; aswingable part 41 having first andsecond end portions middle portion 413 extending between the first andsecond end portions foot retaining part 3 so as to permit rotation of theswingable part 41 relative to thefoot retaining part 3 about a second axis (B) parallel to the first axis (A) and so as to permit co-rotation of theswingable part 41 and thefoot retaining part 3 about the first axis (A) ; afirst locking pin 42 extending transversely relative to theswingable part 41 and secured to thefirst end portion 411 of theswingable part 41 so as to be co-rotatable with theswingable part 41 to thereby engage and disengage a selected one of theretaining grooves 231; a firsturging member 43 for biasing theswingable part 41 to rotate in a first rotation direction to retain thefirst locking pin 42 in the selected one of theretaining grooves 231; and a releasingmember 5 mounted movably on thefoot retaining part 3 and connected to thesecond end portion 412 of theswingable part 41 for rotating theswingable part 41 in a second rotation direction opposite to the first rotation direction so as to disengage thefirst locking pin 42 from the selected one of theretaining grooves 231. - In this embodiment, the first
urging member 43 interconnects thefirst end portion 411 of theswingable part 41 and thefoot retaining part 3. The releasingmember 5 is movable relative to thefoot retaining part 3 along a straight path, and is operable to move in a first direction along the straight path to rotate theswingable part 41 about the second axis (B) in the second rotation direction. The inversion exerciser further includes asecond urging member 52 for biasing the releasingmember 5 to move in a second direction opposite to the first direction so as to rotate theswingable part 41 about the second axis in the first rotation direction. - The inversion exerciser of this invention further includes a
safety lock 6 including aswingable plate 61 that has aheavy end portion 611, alight end portion 612 opposite to theheavy end portion 611, and amiddle portion 613 extending between the heavy andlight end portions swingable part 41 so as to permit rotation of theswingable plate 61 relative to theswingable part 41 about a third axis (C) parallel to the first and second axes (A, B) . Thesafety lock 6 further includes asecond locking pin 62 that is secured to thelight end portion 612 of theswingable plate 61 and that extends transversely relative to theswingable plate 61 for engaging an adjacent one of theretaining grooves 231 when the inversion exerciser is inverted. Theheavy end portion 611 has a weight greater than that of thelight end portion 612 so as to permit rotation of theswingable plate 61 about the third axis (C) by gravity. - The releasing
member 5 includes arod 51 that extends into apost 31 of thefoot retaining part 3 along the straight path, that has an enlargedend portion 511 connected to thesecond end portion 412 of theswingable part 41, and that is urged by the secondurging member 52. Therod 51 is formed with a pushingprotrusion 512 that is disposed above thesecond end portion 412 of theswingable part 41 for driving theswingable part 41 to rotate about the second axis (B) in the second rotation direction when therod 51 is moved in the first direction along the straight path. Aknob 53 is connected to an opposite end of therod 51 for driving movement of therod 51. - When the inversion exerciser is not in a state of use, the
swingable part 41 is urged by the first andsecond urging members first locking pin 42 in the selected one of theretaining grooves 231, as best illustrated inFIG. 3 . - No matter what the position the inversion exercise is to be disposed, i.e., whether an upright or an inverted position, the
heavy end portion 611 of theswingable plate 61 always rotates to a level lower than that oflight end portion 612 by virtue of gravity. As such, when the inversion exerciser is disposed at the upright position, the second-locking pin 62 is disengaged from the adjacent one of theretaining grooves 231, thereby permitting angular adjustment of thefoot retaining part 3 relative to thebeam 2 when thefirst locking pin 42 is disengaged from the selected one of theretaining grooves 231. On the other hand, when the inversion exerciser is disposed at the inverted position (seeFIG. 5 ), thesecond locking pin 62 will engage the adjacent one of theretaining grooves 231, thereby preventing rotation of thefoot retaining part 3 about the first axis (A) even when thefirst locking pin 42 is accidentally disengaged from the selected one of theretaining grooves 231. - When the angle of the
foot retaining part 3 relative to thebeam 2 is to be adjusted prior to use of the inversion exerciser, the inversion exerciser is disposed at the upright position and theknob 53 is pushed downwardly (seeFIG. 4 ) against the urging force of the secondurging member 52 in order to push thesecond end portion 412 of theswingable part 41 via the pushingprotrusion 512 of therod 51 and to rotate theswingable part 41 about the second axis (B) in the second rotation direction, thereby disengaging thefirst locking pin 42 from the selected one of theretaining grooves 231 and permitting rotation of thefoot retaining part 3 about the first axis (A). After the angle of thefoot retaining part 3 has been adjusted, the user can step onto a pair of foot pedals (not shown) on thefoot retaining part 3 and the inversion exerciser can then be inverted to conduct inversion exercise. Thesecond locking pin 62 engages the adjacent one of theretaining grooves 231 immediately after the inversion exerciser is inverted, thereby preventing disengagement from thebeam 2 during the inversion exercise. - By pivoting the
swingable part 41 to thefoot retaining part 3 and securing thefirst locking pin 42 to one end of theswingable part 41, the structure of the inversion exerciser of this invention is made simpler than that of the aforesaid conventional inversion exerciser. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
