Abstract
Description
- This application claims priority under 35 U.S.C. §120 to co-pending application Ser. No. 12/042,368 to Stephen G. Hauser, et al., filed Mar. 5, 2008 in the United States Patent & Trademark Office and entitled “PULLUP EXERCISE ASSEMBLY WITH ROTATBLE HANDLES AND PIVOTABLE BAR”, the disclosure of which is incorporated herein in its entirety by reference.
- 1. Field of the Invention
- Example embodiments of the present invention generally relate to rotatable handle assembly for use with an exercise bar that enhances a pullup and/or chin-up exercise, for example.
- 2. Description of Related Art
- Pullups and chin-ups are exercises consisting of chinning oneself, as on a horizontal bar attached at each end to a frame of a door or doorpost, or of chinning oneself on other outdoor or fitness equipment. Both are compound exercises designed to work the muscles of the upper body. Basically, the difference lies in the grip. One performing a chin-up uses a narrow grip with the palms facing inward, while a pullup is done with typically a wider grip on the bar and with the palms facing outward.
- Traditionally, the exercise of performing a pullup or chin-up places substantial strain on the joints and is limited to exercising certain muscles in the arms, neck and back. Pullup bars with rotatable handle assemblies have been developed to exercise additional muscles in the arms, neck and back. However, these systems do not address or facilitate core muscle exercises (abdominal, trunk).
- An example embodiment is directed to a handle assembly adapted to grasp a bar for exercise. The handle assembly includes a J-shaped hook for placement on the bar, a curved portion forming an upper end of the J-hook adapted to grasp the bar to secure the handle assembly to the bar, a rotation assembly, and a handle attached to the rotation assembly, the handle having an inverted U-shaped bracket with a cross piece defining a grip that is connected between ends of the U-bracket. The rotation assembly is arranged between a lower end of the J-hook and the handle, and includes a bearing having a fastener extending there through that is received within the J-hook lower end to attach the J-hook to the handle. The bearing facilitates rotational movement of the handle. A user grasps the handle to place the curved portion of the J-hook over the bar. The handle is rotated by the user during exercise, via the bearing, about a vertical axis of the J-hook.
- Another example embodiment is directed to a handle assembly adapted to grasp a bar for exercise. The handle assembly includes a J-shaped hook for placement on the bar, a rotation assembly and a handle attached to the rotation assembly. The handle has an inverted U-shaped bracket with a cross piece defining a grip that is connected between ends of the U-bracket. The rotation assembly is connected between a lower end of the hook and the U-shaped bracket and includes a bearing, the handle being rotatable via the bearing by a user during exercise with the J-hook on the bar.
- Example embodiments of the present invention will become more fully understood from the detailed description given herein below and the accompanying drawings, wherein like elements are represented by like reference numerals, which are given by way of illustration only and thus do not limit the example embodiments.

FIG. 9 illustrates a user performing an Australian pullup on theexercise assembly 1000. -
FIG. 10 illustrates a user performing a standing row on theexercise assembly 1000. - The example embodiments in general relate to a pullup exercise assembly that includes rotatable handle assemblies and a pivotable bar assembly which can be oriented and secured into various positions between two vertical surfaces, such as the doorposts or sides of a door frame. The example exercise assembly can combine the pullup and chin-up exercise, and can be used for performing core exercises such as an inverted pushup (known as an “Australian pullup”), standing row exercise and a dip exercise, for example.
-
FIG. 1 is a perspective view of an exercise assembly in accordance with the example embodiments. The pullup exercise assembly, hereafter “exercise assembly 1000”, is shown positioned betweenvertical surfaces 305 of aframe 300. Theexercise assembly 1000 includes abar assembly 200 comprising acentral bar 205 connected between a pair ofside arm assemblies 250. Thecentral bar 205 may include a rubber overmold grip, for example. One ormore handle assemblies 100 can be affixed to thecentral bar 205 via a J-hook 110 that forms part of thehandle assembly 100. - The
handle assembly 100 includes a J-hook 110, arotation assembly 120, and ahandle 130. The J-hook 110 grips thecentral bar 205. The J-hook 110 is connected to therotation assembly 120, which in turn is connection to thehandle 130. The J-hook 110 remains fixed in place as thehandle 130 can be rotated around the axis of the J-hook 110 via therotation assembly 120. - Each
side arm assembly 250 includes avertical side strut 252 connected to ahorizontal end stub 254. Theend stub 254 can be welded to theside strut 252. Theside struts 252 extend along thevertical surface 305 between an upper hook mount 215 (which receives the portion of the side-arm assembly where theend stub 254 is attached to the side strut 254) and alower mount 251 which includes apivot pin 255 that extends through aslotted aperture 253 in theside strut 252. - The
bar assembly 200 can pivot about thepivot pins 255. In an example, thebar assembly 200 is first lifted out of theupper hook mounts 215 to unlock thepivot pin 255, such that thepin 255 slides down into the wider part of theslotted aperture 253. Thebar assembly 200 can then be rotated to a desired angle from vertical to perform a different exercise such as a dip, standing row, inverted pullup, etc. - As shown in
FIG. 1 , thebar assembly 200 includes a centralhollow metal bar 205, which can be covered with an overmold grip, as previously described. Thecentral bar 205 is dimensioned so that its inner diameter is slightly larger than the outer diameter of theend stubs 254. Accordingly, theend stubs 254 are received within thecentral bar 205, and may be secured viaretaining rings 210. -
FIG. 2 is a perspective view of the handle assembly in accordance with the example embodiments. Thehandle assembly 100 is a standalone component; in other words it is freely removable from thebar 205 and is not fixed to thecentral bar 205 by a connection means which requires assembly/disassembly, such as a pin, screw or actuation mechanism which locks and unlocks thehandle assembly 100 from thecentral bar 205. - The J-
hook 110 includes an uppercurved portion 112, an elongate intermediate body that is generally semi-circular in shape and which forms a circular shape at abase 116 of thehook 110. The J-hook 110 may be made of a metal material such as steel (which may be painted for stylistic purposes), and alloy thereof, aluminum, etc. Thehandle 130 is connected to therotation assembly 120 at aneck 139. Thehandle 130 includes ametal U-bracket 132 having agrip member 138 secured therein by way of threadedfasteners 134. The U-bracket 132 may be made of a medium or heavy gauge impact plastic such as acrylonitrile butadiene styrene (ABS), or of a metal material such steel, and alloy thereof, cast aluminum, etc. Thefasteners 134 may be pins for example. -
FIG. 3 is an exploded view of the handle assembly ofFIG. 2 to illustrate components in greater detail. Therotation assembly 120 includes a generally circular orcylindrical bearing 119 which is positioned between awasher 125 and an internally threadedplug 118. The bearing 119 permits thehandle 130 to be rotated 360 degrees in either direction around a vertical axis of the J-hook 110 that is perpendicular to thebar 205 during exercise. Theplug 118 receives ahex bolt 126 such that the external threads onbolt 126 mate with internal threads withinplug 118 to connect the J-hook 110 withhandle 130. Theplug 118 has a hex head shape that is a standard profile for an Allen wrench, and fits into abore 117 formed inbase 116. As can be seen inFIG. 3 ,bolt 126 extends throughneck 139,washer 125 andbearing 119, to be threaded into theplug 118. - The
rotation assembly 120 includes arubber bellow 128 between thehook 110 and theneck 139 of thehandle 130. At its top, the rubber below 128 attaches to thebase 116 of the J-hook 110. Therubber bellow 128 mates with theneck 139 ofhandle 130 at its bottom so that a portion of theneck 139 contacts an interior surface of thebellow 128. The rubber below 128 encloses thewasher 125 and a portion of thebolt 126 extending there through. - The
handle 130 includes ahollow metal shaft 137 overlaid with or sheathed withingrip member 138.Shaft 137 may be composed of chrome steel or aluminum, for example, and is secured to arms of the U-bracket 132 via insertion offasteners 134 throughholes 133 in theU-bracket 132. Thegrip member 138 may be made of a foam rubber or suitable elastomeric material and has a wider or thicker center portion which tapers down to the end portions of the grip member 148. - The
bearing 119 has an opening for receiving thebolt 126. When thehandle assembly 100 is assembled, the bearing 119 fits up into abore 117 formed within thebase 116 of the J-hook 110, contacting an underside surface ofplug 118. -
FIG. 4 is a front view of the handle assembly ofFIG. 2 , andFIG. 5 is a cross-section view of the handle assembly inFIG. 4 taken across a line A-A. Referring toFIGS. 4 and 5 , the relationship between moving and fixed components withrotation assembly 120 can be seen in greater detail. Thebearing 119 is designed to rotate around the fixedbolt 126 with thehook 110 being fixed on thecentral bar 205 and the user swiveling or rotating thehandle 130 around therubber bellow 128 such that theneck 139 and bearing 119 rotate together. Thus, thebearing 119 and handle 130 rotate together for desired rotational movement in either direction. -
FIG. 6 is a partial exploded view of thebar assembly 200 to illustrate components in greater detail, andFIG. 7 is a partial exploded view of thebar assembly 200 to illustrate connection thereof between vertical surfaces. Referring toFIGS. 6 and 7 , the outer ends of eachend stub 254 are attached to corresponding upper ends of the side struts 252. The portion of the side-arm assembly 250 shown in circle B ofFIG. 7 is received into theupper hook mount 215. Theupper hook mount 215 includes achannel 216 to receive the end ofend stub 255 and top ofside strut 252 at the intersection thereof. Thus, thechannel 216 has a sufficient width to accommodate the upper portion of the side-arm assembly 250, as shown best inFIG. 7 . Theupper hook mount 215 is secured to avertical surface 305 of adoor frame 300 for example by suitable fasteners 217 (such as wood screws) throughholes 219 formed in theupper hook mount 215. - A
lower pivot mount 251 is provided to enable thebar assembly 200 to be pivotable, once the top of theassembly 200 is lifted out of thechannels 216 of the hook mounts 215. Thelower pivot mount 251 is secured to thevertical surface 305 by suitable fasteners 258 (such as wood screws) throughholes 259 formed in thelower pivot mount 251. Thelower pivot mount 251 contains thepivot pin 255. Thepivot pin 255 has a post with amushroom head 257 that is configured to extend into the larger opening of the slottedaperture 253. Once the desired location of thebar assembly 200 is set, i.e., theassembly 200 has either (a) been set for conventional pullup/chin-up exercises, or (b) has been pivoted to some desired angle from vertical for another exercise, themushroom head 257 captures surfaces of the side struts 252. - For example, once the
bar assembly 200 has been pushed downward so that thepivot pin 255 rides up thenarrower channel 256 of slottedaperture 253, themushroom head 257 of thepivot pin 255 captures surfaces of the side struts 252 along the slottedaperture 253. Exercising may begin. In one example, thebar assembly 200 can be removed from thechannels 116 of the upper hook mounts 215 and rotated up to 180 degrees to a lower dimension, pivoting around the lower pivot mounts 251 so as to permit one to perform inverted pushup exercises from the ground up, a standing rowing exercise, a dip exercise etc. -
FIG. 8 illustrates a user performing a conventional pullup or chin-up exercise on theexercise assembly 1000. Since thehandle assemblies 100 swivel, the user's hands can rotate as the user is moving up and down, engaging additional muscle groups. -
FIG. 9 illustrates a user performing an Australian pullup on theexercise assembly 1000. In this example, the fitness trainer has oriented theexercise assembly 1000 such that the side struts 252 andcentral bar 205 have been rotated downward approximately 180 degrees from vertical. In this orientation, the trainer can perform a reverse pushup (Australian pullup) to work different muscles than can be achieved with a conventional pullup/chin-up bar. -
FIG. 10 illustrates a user performing a standing row on theexercise assembly 1000. In this example, the fitness trainer has oriented theexercise assembly 1000 such that the side struts 252 andcentral bar 205 have been rotated downward approximately 120 degrees from vertical. In this orientation, the trainer can perform a rowing exercise to work the core abdominal muscles, in addition to working the biceps, deltoids, pectorals and other back muscles. -
FIGS. 8 through 10 are merely example orientations of theexercise assembly 1000 to perform exercises other than standard pull-ups or chin-ups. It would be evident to one or skill in the art to re-position the side-arm assemblies 250 andcentral bar 205 to perform exercises other than shown inFIGS. 8-10 . - Therefore, unlike traditional pullup or chin-up bars that limit the user's range of motion, the
example exercise assembly 1000 includes twisting handles 130 onadjustable swing arms 250 which attach to thecentral bar 205 to maximize muscle motion. Thehandle assemblies 100 incorporatebearings 119 to enable 360 degree rotation. This permits the user's arms to move naturally, reduces strain on joints, and engages additional muscle groups as compared to the standard pullup bar. Theexample exercise assembly 1000 thus may combine the standard pullup and chin-up exercises into one, and can facilitate additional workouts to core and abdominal muscle groups. - The example embodiments being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as departure from the embodiments of the present invention. All such modifications as would be obvious to one skilled in the art are intended to be included within the following claims.
