1. Field
Example embodiments of the present invention generally relate to an exercise assembly adapted for performing a dip exercise and other exercises.
2. 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 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).
Further, traditional pull-up and chin-up bars do not allow for the performance of dip exercises. The user must use a separate dip bar having horizontal handles in order to perform a dip. These conventional dip bars have a fixed width between the handles.
An example embodiment of the present invention is directed to an exercise assembly that includes a pivotable bar assembly and a dip bar assembly. The pivotable bar assembly extends through a frame and has a central bar connected between first ends of a pair of swings arms, with second ends of the swing arms pivotably connected to facing surfaces of the frame. The dip bar assembly extends across a front side of the frame and includes a main tube with a pair of handles extending outward from the main tube and resting on the center bar of the bar assembly.
Another example embodiment is directed to an exercise assembly that includes a bar assembly attached to a frame and configured to be pivoted at one end so as to extend outward through the frame, and a dip bar assembly extending across a front side of the frame and including a pair of handles extending outward from a main tube of the dip bar assembly and resting on the bar assembly.
Another example embodiment is directed to a dip bar assembly for placement against a frame. The assembly includes a pair of end stubs, a main tube and a pair of handles extending outward from the main tube. The main tube is secured between the end stubs, with ends of the end stubs terminating in bumpers which engage a front surface of the frame. Each end stub includes a bracket for supporting a swing arm of a pivotable bar assembly therein so that the swing arms are angled outward from the frame toward the dip bar assembly.
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.
The dip bar assembly 300 includes a main tube 305 secured between a pair of stub tubes 310 by collars 315. The ends of the stub tubes 310 terminate in bumpers 330 that protect the frame 400. The dip bar assembly 300 includes a pair of handles 350 attached to the main tube 305 and also attached to the central bar 205 of the bar assembly 200. The handle 350 may include an over-mold material thereon, such as foam rubber, to provide a non-slip surface.
Additionally, the dip bar assembly 300 includes a pair of brackets 320 designed to receive and support the swing arms 250, as shown in

A lower pivot mount 251 (shown generally as the pivot point 275 in
For example, once the bar assembly 200 has been pushed downward so that the pivot pin 255 rides up the narrower channel 256 of slotted aperture 253, the mushroom head 257 of the pivot pin 255 captures surfaces of the side struts 252 along the slotted aperture 253. Exercising may begin. In one example, the bar assembly 200 can be removed from the channels 216 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.
With a load on the exercise assembly 100, the forces induced by the weight are absorbed by the bar assembly 200 and dip bar assembly 300 against the frame 400. The downward force on handles 350 is absorbed in part by the central bar 205, which in turn is secured in the brackets 320 of the dip bar assembly 300. The main tube 305 and stub tubes 310 also absorb the forces imparted on the handles 350, and the bumpers 330 protect the frame 400 against damage.
The handles 350 are infinitely or variably adjustable in width, within the constraints the main tube 305, i.e., to the collars 315. This is unlike conventional dip bars which have fixed widths between the handles. Each handle 350 includes a collar 351 integrally formed and having a bore 352 so as to slide over the main tube 305, to be set at any desired position on the main tube 305. An angled arm 353 extends downward from the collar 351 and flares out to a level grip end 355. Each angled arm 353 includes a support 354 on an underside thereof. Each support 354 is designed to rest on the central bar 205 of the bar assembly 200. Each grip end 355 can include an over-mold grip 356 and a decorative end cap 358 that inserts into the bore 357 of the grip end 355 once the grip 356 has been slipped over grip end 355.
The half-round feature 326 locates the main tube 305 of the dip bar assembly 300 at the proper height along the swing arms 250 so that the supports 354 on the underside of the angled arms 353 of the handles 350 do not gouge the foam rubber cover of the central bar 205. The half-round features 326 secure the dip bar assembly 300 to the swings arms 250, preventing the dip bar assembly 300 from falling if the central bar 250 is ever pulled away from the door frame 400.
The handle assembly 500 includes the J-hook 510, a rotation assembly 520, and a handle 530. The J-hook 510 grips the central bar 205. The J-hook 510 is connected to the rotation assembly 520, which in turn is connection to the handle 530. The J-hook 510 remains fixed in place as the handle 530 can be rotated around the axis of the J-hook 510 via the rotation assembly 520. As will be shown hereafter, the handle assemblies 500 can be used in conjunction with the dip bar assembly 300. As shown, the bar assembly 200 is configured for pull-ups and chin-ups.
As previously noted, the bar assembly 200 can pivot about the pivot pins 255. In an example, the bar assembly 200 is first lifted out of the upper hook mounts 215 to unlock the pivot pin 255, such that the pin 255 slides down into the wider part of the slotted aperture 253. The bar 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.
The central hollow metal bar 205 can be covered with an over-mold grip, as previously described. The central bar 205 is dimensioned so that its inner diameter is slightly larger than the outer diameter of the end stubs 254. Accordingly, the end stubs 254 are received within the central bar 205, and may be secured via retaining rings 210.
The rotation assembly 520 includes a rubber bellow 528 between the hook 510 and the neck 539 of the handle 530. At its top, the rubber bellow 528 attaches to the base 516 of the J-hook 510. The rubber bellow 528 mates with the neck 539 of handle 530 at its bottom so that a portion of the neck 539 contacts an interior surface of the bellow 528. The rubber below 528 encloses the washer 525 and a portion of the bolt 526 extending there through.
The handle 530 includes a hollow metal shaft 537 overlaid with or sheathed within grip member 538. Shaft 537 may be composed of chrome steel or aluminum, for example, and is secured to arms of the U-bracket 532 via insertion of fasteners 534 through holes 533 in the U-bracket 532. The grip member 538 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 548.
The bearing 519 has an opening for receiving the bolt 526. When the handle assembly 500 is assembled, the bearing 519 fits up into a bore 517 formed within the base 516 of the J-hook 510, contacting an underside surface of plug 518.
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.
