This disclosure focuses on certain features with the understanding that other features of the inversion apparatus 100 may be gleaned from the above-referenced patents.
The base 10 includes two pairs of legs 11 having upper ends pivotally coupled together with two apex plates 12, thereby forming two inverted V-shaped or A-shaped frames 13. The table is pivotally or rotatably attached to and supported on the apex plates 12 of the base 10 with pivot axles 14, which pivot with the table 16 relative to the apex plates 12, between a normal status or non-inverted, ready position (see
The table 16 may be described in terms of a body supporting platform and an extension or bar 21 that is attached to and/or extends from the lower end of the platform. A foot engaging assembly or lower limb engaging assembly 105 is mounted on a lower end portion of the extension 21. The foot engaging assembly 105 may be described in terms of an ankle holder or clamp 103 and a foot rest 104, which cooperate to hold, retain, and/or position the feet and ankles of a user relative to the table 16. The extension 21 is preferably telescopically adjustable relative to the platform for moving or adjusting the ankle holder 103 and the foot rest 104 toward or away from the platform, according to the height or dimension of the user.
When the tilting inversion exerciser 100 occupies or is rotated to the relaxed or unloaded or non-inverted or generally upright position shown in
The ankle holder 103 includes a fixed rear ankle support 3 having left and right rear padded cuffs 31 attached to the extension 21 to comfortably engage with and support the backs of a user's ankles A. In this regard, a cylindrical tube or hollow rod 32 extends laterally through a hole in the extension 21, and is secured in place by a bolt 33 and a nut 34, as shown in
The ankle holder 103 also includes an adjustable front ankle support 4 having left and right front padded cuffs 43 attached to the extension 21 to comfortably engage with and support the fronts of a user's ankles A. In this regard, a square tube or shank or support 25 extends forwardly through a hole in the extension 21, proximate its lower distal end (and beneath the bolt 32). The shank 25 preferably extends perpendicularly through the extension 21, and is welded in place. The shank 25 defines a compartment or chamber 26 having an open or unobstructed forward end. A column or stem 40 is slidably mounted or engaged in the chamber 26 of the shank 25 and projects out the forward end. A cylindrical tube or hollow rod 41 extends laterally through a hole in the stem 40, proximate a forward end 42 of the stem 40, and is secured in place by a bolt 48 and a nut 49, as shown in
As further explained below, the cuffs or anchor members 43 may be adjusted and moved toward or away from the cuffs 31 to accommodate the ankles of various users. In other words, people of different dimensions and/or standards may be suitably and snugly fitted and engaged between respective pairs of cuffs 31 and 43, thereby solidly and stably anchoring or retaining or positioning the ankles of the user to the extension 21 of the table 201.
As shown in
The stem 40 further defines or includes one or more holes or orifices 46 formed in and extending through an upper portion or second surface 47 thereof. The holes 46 cooperate with a lock device 5 to secure the front ankle holder 4 in a desired location relative to the rear ankle holder 3. In this regard, a hole extends through an upper surface or sidewall of the shank 25, and a barrel or tubular member 28 is welded onto the shank in alignment with the hole. The barrel 28 extends perpendicularly upward from the shank 25 and defines a bore 29 in communication with the chamber 26 defined by the shank 25 to accommodate the latch or lock device 5.

A tag or label 59 is preferably mounted on top of the button 56 to call attention to the exposed or protruding button 56 and/or the label 59 and provide or indicate a warning signal that the tongue 51 of the rod 50 is not engaged with any of the orifices 46 of the stem 40. In this misaligned position, the stem 40 and the cuffs 43 are free to move relative to the cuffs 31, meaning the feet of the user may not be solidly and stably anchored or retained or positioned to the extension 21 for purposes of inversion.
In operation, the tilting inversion exerciser in accordance with the present invention includes an ankle holder for adjustably securing the ankle portions of the user, and for giving some security to the user while conducting the inversion exercises, and for preventing the feet of the user from being inadvertently disengaged from the foot and ankle engaging assembly, and thus for allowing the user to safely conduct inversion exercise.
The foot rest 104 is attached or mounted or secured to a bottom or distal end portion 22 of the extension 21 (beneath the shank 25). The foot rest 104 includes one or more and preferably two foot pedals 60a and 60b sized and configured to underlie and stabilize and support the feet F of the user, and/or to be stepped on by the feet F of the user. In this regard, a square tube or shank or support 23 is welded to the lower end of the distal end portion 22, and extends forward and downward from the end portion 22. The tube 23 defines a chamber or compartment 20 that opens forwardly in a direction generally away from the extension 21. The left and right foot pedals 60a and 60b are selectively rotatably mounted to the tube 23. As further described below, a lock assembly or device 7 is sized and configured for insertion into the open forward end of the chamber 20.
A cylindrical tube or hollow rod 80 extends laterally through holes in the sidewalls of the tube 23 and through an aligned opening in the device 7 to secure the device 7 inside the tube 23. The left foot pedal 60a slides onto an outwardly projecting left end of the rod 80, and the right foot pedal 60b slides onto an outwardly extending right end of the rod 80. Screws 87 insert through holes in respective foot pedals 60a and 60b, and thread into aligned holes 81 in respective ends of the rod 80 to fasten the foot pedals 60a and 60b to the rod 80 and capture the tube 23 therebetween. In the absence of other influences, this arrangement rotatably mounts the rod 80 (and the foot pedals 60a and 60b) on the tube 23 for rotation about a longitudinal axis defined by the rod 80. In terms of structure, the left pedal 60a and the right pedal 60b are mirror images of one another.
The left and right pedals 60a and 60b share a common eccentricity relative to the rod 80, and each includes a plurality of and preferably three alternative foot bearing surfaces 61-63 disposed about the outer peripheral portion thereof. Each surface 61-63 is arranged and located at a different radius or spacing distance from the rod 80, and thus, establishes a different foot supporting location relative to the rod 80 and the support 25 associated with the ankle holder 103. For example,
The rod 80 has or defines one or more and preferably three holes or orifices 82-84 formed through the middle or intermediate portion of the rod 80. The orifices 82-84 occupy respective circumferentially spaced locations at a common axial location along the rod 80. The axial location of the orifices 82-84 aligns with the center of the tube 23 and places the orifices 82-84 in communication with the chamber 20 defined by the tube 23.
The latch or lock device 7 is disposed or engaged in the chamber 20 of the tube 23, and may be described as a means for releasably latching or locking the rod 80 and the foot pedals 60a and 60b in the different angular positions. The lock device 7 includes a casing or lever or bar comprised of two identical left and right inserts or halves 72 and 73, one of which is flipped 180 degrees relative to the other. The inserts 72 and 73 are sized and configured to come together and register or mate with one another in a manner that defines a through hole 74. After the device 7 is assembled and inserted into the chamber 20, the rod 80 is inserted through the hole 74 and the aligned holes in the sidewalls of the tube 23, as described above.
The inserts 72 and 73 cooperate to retain three movable parts therebetween. In this regard, the inserts 72 and 73 have inner end portions that define a stepped down rail that extends between relatively larger flanges on respective inserts 72 and 73. The hole 74 extends through a central portion of the rail. A U-shaped follower or first movable part 70 is configured to straddle the rail between the flanges. The follower 70 has an inner end or base portion that wraps or curves around the distal inner end of the rail, which in turn, wraps or curves around the rod 80. The base portion supports a peg or tongue or projection 71 that projects away from the base portion of the follower 70 and toward the rod 80. The follower 70 has first and second legs or prongs 77 that extend away from respective ends of the base portion to respective outer ends, which are bent toward one another to define first and second tabs 78.
The inserts 72 and 73 have outer end portions that define a lipped or rimmed opening proximate the open front edge of the chamber 20. The rimmed opening has a square profile that nest concentrically inside the square profile of the chamber 20. The inserts 72 and 73 also have intermediate portions that define a channel between the rimmed opening and the rail.
A knob or button or second movable part 75 has an inner end portion sized and configured to fit between the prongs 77 on the follower 70 and to resist extraction from the chamber 20 through the rimmed opening. The inner end portions defines first and second grooves or slots 79 that open in opposite directions to receive and retain respective tabs 78. A helical coil spring or bias member or third movable part 76 is placed in series or compressed between a distal inner end of the knob 75 and an opposing end of the rail, thereby biasing the knob 75 away from the rail (and away from the inserts 72 and 73). The knob 75 has a stepped down intermediate portion or neck that extends through the rimmed opening, and an outer end disposed outside the inserts 72 and 73, and sized and configured to be pushed by the thumb or fingers of the user.
The foregoing arrangement is such that the knob 75 is slidable relative to the inserts 72 and 73 between a relaxed or latched or extended position, shown
