Description
Background of the Invention
The invention relates to an apparatus for performing exercises, particularly those known as "push-ups".
Several devices on which push-up exercises may be performed have been patented. Such devices are disclosed in U.S. Pat. No. 2,666,640 (Jennings); U.S. Pat. No. 4,327,907 (DeVries); and U.S. Pat. No. 4,610,448 (Hill). Many prior art devices support a handle or handles at a fixed distance from a surface, usually the floor. Such prior art devices do not provide a way of easily adjusting the distance between the handle and the surface and consequently cannot adequately accommodate a person in various stages of conditioning.
Summary of the Invention
The invention reduces the limitations of the prior art push-up exercising apparatus by providing an apparatus which is easily adjusted to increase or decrease push-up difficulty. The invention allows the user to place the apparatus in one of a plurality of orientations, for example three orientations, thereby positioning a handle, on which the push-ups are to be performed, at one of three different distances from the surface such as a floor. Two similar apparatuses are used, the user holding onto one in each hand and pushing on the apparatuses to raise himself from the floor.
A person just starting to condition himself would begin training by orienting the two apparatuses so that the handles with the shortest distance to the floor are rendered operative. As the person progresses in conditioning, the two apparatuses would be re-oriented to render operative the handles with the next shortest distance to the floor. As the person further progresses, the two apparatuses would be re-oriented to render operative the handles with the furthest distance to the floor, thus providing maximum exercising difficulty.
By combining the orientation of the apparatuses with the way in which the user may choose to place the apparatuses on the floor, push-up exercises may be used to strengthen several areas of the body such as triceps, front and rear deltoids, biceps, pectoral muscles and the like. In addition, the apparatuses may be used for performing quick dip exercises for further upper body strength and conditioning.
Another embodiment of the apparatus according to the invention is for performing push-up exercises, etc. on a surface such as a floor. The apparatus includes a handle and first and second supports. The first and second supports both have first and second sides for placement of the supports on the surface. The handle is supported at a first distance from the first side and at a second different distance from the second side. The first and second supports may be oriented to place the first sides on the surface thereby positioning the handles thereof at the first distance from the floor. Similarly the first and second supports may be oriented to place the second sides on the surface thereby positioning the handles thereof at the second distance from the floor. The handles have a plurality of longitudinal grooves to prevent slippage of a hand gripped thereon. The handles can be releasably attached to the supports and have locking tabs and depth stops which cooperate with collars on the first and second supports to securely hold the handles and prevent axial movements of the supports. The handles also have a longitudinal groove forming a keyway to engage with the keying member in the collars to prevent rotation.

Description of the Preferred Embodiments
Referring to FIG. 1, a pair of exercising apparatuses is shown generally at 10 in use by a person 12 performing push-up exercises on a surface 14.
Referring to FIG. 2, a single exercising apparatus is shown generally at 16, comprising a first handle 18, a second handle 20 and a third handle 22, all the handles being similar. Each handle is operably connected to, and extends between, a first support 24 and a second support 26. The first and second supports 24 and 26 are similar, and consequently only the first support 24 will be described in detail. The support 24 has an equilateral triangular shape comprising a first side 28, a second side 30 and a third side 32.
Referring to FIG. 3, the first support 24 includes a first collar 34 having an opening 35, the collar providing first holding means for holding the first handle 18. The first support 24 also includes a second collar 36 having an opening 37 and a third collar 38 having an opening 39, the collars 36 and 38 providing second and third holding means respectively.
Each collar 34, 36 and 38 is supported by first, second and third brace means respectively, which include a web member 40 extending between the collars 34, 36 and 38, a plurality of inner stiffening members 42 also extending between the collars and a plurality of outer stiffening members 43 extending from the sides 28, 30 and 32 to the collars 34, 36 and 38 and the inner stiffening members 42. The combination of the collars 34, 36 and 38, the inner stiffening members 42, the outer stiffening members 43 and the web member 40 provide first, second and third means for supporting the first, second and third handles 18, 20 and 22 respectively.
The collars 34, 36 and 38 are supported generally adjacent vertices of the triangular shape and at different perpendicular distances from respective sides 28, 30 and 32 disposed oppositely to the respective vertices. The first collar 34 is supported at a first distance 44 from the first side 28. The second collar 36 is supported at a second different distance 46 from the second side 30, and the third collar 38 is supported at a third different distance 48 from the third side 32.
Referring to FIGS. 4 and 6, the handle 18 includes a first end portion 54 and a second, similar end portion (not shown) at an opposite end of the handle. The end portion 54 includes spaced apart first and second guide members 58 and 60 which are disposed on each side of the end portion and form keyways 62 and 63 on generally diametrically opposite sides of the end portion, as best seen in FIG. 6. The guide members 58 and 60 extend from a diametrical web member 65 and all three members extend the length of the handle. The end portion 54 also includes first and second locking tabs 64 and 66 attached to longitudinally extending outer segments 67 and 69 of the handle by first and second resiliently bendable portions 68 and 70.
A first cam portion 72 having a first tapered surface 74 extends from the end of the first locking tab 64. A second cam portion 76 having a second tapered surface 78 extends from the end of the second locking tab 66. The first and second tapered surfaces 74 and 78 are adapted for contact with an end face of the collar 34 when the first end portion 54 is pushed against the collar for insertion therein.
As shown in broken outline in FIG. 4, as the first end portion 54 is pushed against the first collar 34, the first and second cam portions 72 and 76 and hence the first and second locking tabs 64 and 66 are deflected inwardly, bending about the first and second resiliently bendable portions 68 and 70 as indicated by broken lines at 72.1 and 76.1.
Referring to FIG. 5, the first end portion 54 is shown after having been pushed through the collar 34 until first and second depth stops 80 and 82 are in contact with the first collar 34. At this point, the first and second cam portions 72 and 76 have passed through the first collar 34. Thus the first collar 34 is no longer in contact with the first and second tapered surfaces 74 and 78, and consequently the first and second cam portions 72 and 76 and the first and second locking tabs 64 and 66 are no longer deflected. The first and second resilient portions 68 and 70 return the first and second locking tabs 64 and 66 to their original position, and the assembly of the first end portion 54 into the first collar 34 of the first support 24 is then complete.
The first support 24 is prevented from axial movement towards the middle of the first handle 18 by the first and second depth stops 80 and 82. Axial movement of the support 24 away from the middle of the first handle 18 is prevented by interference with first and second shoulders 81 and 83 at inner ends of the first and second cam portions 72 and 76.
The handle 18 further includes first and second longitudinal grooves 84 and 86 on each side thereof. The grooves 84 and 86, and similar parallel grooves which are continuations of the keyways 62 and 63 extend lengthwise of the handle and provide means to prevent slippage by a hand gripped thereon.
Referring again to FIG. 6, the collar 34, which is representative of collars 36 and 38, is shown including first and second keying members 50 and 52 located diametrically opposite each other and extending radially inward from the collar. The first and second keying members 50 and 52 ensure correct orientation and prevent rotation of the handle so that the segment 67, without grooves, is uppermost for comfortable gripping.
Rotation of the handle is prevented by the engagement of the first and second keying members 50 and 52 with the keyways 62 and 63 respectively on each side of the first end portion 54.
The first end portions of the second and third handles 20 and 22 are assembled onto the first support 24 in the manner just described. The second end portions of the first, second and third handles 18, 20 and 22 are similar and are also assembled onto the second support in the same manner as described above.
Referring to FIGS. 4 and 5, to disassemble the first handle 18 from the first support 24, the first end portion 54 is removed from the first collar 34 as follows. The first and second cam portions 72 and 76 may be squeezed inwardly, consequently deflecting the first and second locking tabs 64 and 66 inwardly against the force of the first and second resilient portions 68 and 70. The shoulders 81 and 83 disengage from the collar 34 and the first handle 18 may be pulled away from the first support 24, thereby freeing the first handle 18. The second and third handles 20 and 22 are disassembled from the first support 24 in the same manner. The first, second and third handles 18, 20 and 22 are disassembled from the second support 26 in the same manner as described above.
The apparatus described herein has three sides and is presented by way of preferred example only. Other apparatuses having two or more sides, which support one or more handles at different distances from a surface, depending on the orientation of the apparatus, could be devised.
