Description

Docket 11749C
PUSHUP EXERCISER HAVING MULTIPLE HAND POSITIONING
SPECIFICATION
Field of the:Invention 100011 This invention relates generally to fitness and exercise apparatus and particularly to fitness and exercise apparatus used to perform pushup exercises.
Background of the Invention

[0002] Perhaps one of the most well-known and frequently employed types of exercises is that generally referred to a "pushups". While pushups may be performed in a variety of routines, the most basic pushup exercise is performed by the participant laying face down upon a floor surface with the upper feet and toes supporting the lower portion of the body and with arms extended outwardly and downwardly placing hands approximately beneath the participant's shoulders. Frequently, the participant supports the participant's hands upon the floor surface using extended fingers and thumb to actually touch the floor surface. In this position, the participant then stiffens and maintains a rigid straight line body position while pushing the body upwardly using the participant's arms until the arms are fully extended and the participant's body is supported upon the foot and toes together with the participants hands.
Thereafter, the participants simply lowers and raises the body using the participant's arms.
In many instances, the objective of a "perfect" pushup is attained by lightly touching the chest to the floor between the participant's hands during each downward movement.

[0003] Among the many variations of pushup exercises utilized, one is well-known for accommodating persons having limited upper body and arm strength in which the lower body is supported upon the participant's knees rather that foot and toes. When so supported, the pushup requires substantially less upper body and arm strength for exercise. At the opposite extreme, persons seeking to increase the effort required for the pushup exercise often utilize a single supporting hand and perform the so-called one handed pushup. By way of further variation, participants often utilize different hand positions such as wider or narrower spacing to add variety to the pushup exercises. Additionally, participants may choose to rotate the hand positions upon the floor for further variation of the exercise.

[0004] Recognizing the long term popularity and effectiveness of pushups as a fitness and conditioning exercise, practitioners in the art have endeavored to provide a variety of apparatus which is utilized in performing exercises. One such example is an apparatus produced and marketed under the product name "the strength builder" which utilizes an elongated flat board having a plurality of closed end holes formed therein. A pair of cooperating handles is provided each of which includes an inverted U-shaped handle grip supported upon a small generally flat platform base. The platform base further includes a downwardly extending generally cylindrical post at one end of the platform. The posts on the handles are sized and shaped to be received within the closed end apertures one elongated board. The board further includes a plurality of indicia lines together with numerals to identify hand locations and angular positions upon the board for each of the handles. In its intended use, the user places the posts of each of the handles into the selected closed end apertures on the board and rotates the handles to the desired angular position upon the board. Thereafter, the user grips the upper portion of the inverted U-shape handle grips and performs pushup exercises thereon.

[0005) Another variation of pushup exercise product provided by practitioners in the art is sold under the product name "perfect pushup mobile unit" sold by Perfect Fitness. The perfect pushup mobile unit apparatus includes a pair of generally disk shaped circular platforms each having an inverted U-shape handle pivotally secured to the edges thereof, The handles are pivomble between a vertical position intended for use and a flat position intended for storage and transport. In the anticipated use of the perfect pushup mobile unit product the participant grips each inverted U-shaped handle and positions the circular bases thereof upon the floor and thereafter assumes the typical pushup position. The user is able to pivot thc hand grip units to set a particular rotational position of the participant's hands during the pushup exercise. Thereafter, the pushup exercise is carried forward in the conventional fashion. By way of further variety, a plurality of similar products are sold which are generally described in the art as "pushup stands"
which are characterized by pairs of hand units each including a band grip portion. In the most typical stand configuration, the hand grip portion includes an inverted U-shaped member having downwardly extending legs each of which is joined to a short transverse floor piece in a right angle attachment Variations of this pushup stand apparatus are provided by fabricating variously formed tubular material shapes all of which are employed in a similar manner to perform pushup exercises.

[0006) While the foregoing described prior art devices have to some extent improved the art and have in some instances enjoyed commercial success, there remains nonetheless a continuing need in the art for ever more improved pushup exerciser apparatus.

Summary of the Invention

[0007] Accordingly, it is a general object of the present invention to provide an improved exercise apparatus suitable for pushup exercise activities. It is a more particular object of the present invention to provide an improved apparatus for pushup exercise which facilitates and orderly and organized sequence of hand positions during pushup exercises. It is a still more particular object of the present invention to provide an improved apparatus for pushup exercise which maintains the handles of the pushup apparatus in a secure non-pivoting reliable and repeatable position, [was] In accordance with the present invention, there is provided apparatus for performing pushup exercises, the apparatus comprising: a generally planar board defining a generally planar top surface; a plurality of post receptacles formed in the top surface; a pair of handle units each having attachment means for engaging selected ones of the post receptacles in a fixed location and angular orientation upon the top surface; and a plurality of color indicia formed on the top surface in association with selected ones of the post receptacles, the color indicia defining groups of color indicia each group being distinguishable from other groups by a characteristic color whereby the post receptacles and the color indicia groups cooperate to define selected positions of the handle units upon the board.

100271 Figure 1 sets forth a perspective view of a pushup exerciser constructed in accordance with the present invention and generally referenced by numeral 10.
Pushup exerciser includes a board 11 formed by a pair of board sections 12 and 13 joined along a board section junction 14. In combination, board sections 12 and 13 form a generally planar elongated board 11 which, in accordance with the present invention, receives a pair of handle units 30 and 40 at selected positions upon board 11 to fa.cilitate the multiple hand position pushup exercise activity.
It will be apparent to those skilled in the art from the descriptions which follow that the present invention pushup exerciser facilitates a substantial variety of hand positions and angles each of which is maintained in a secure attachment of handle units 30 and 40 once a position set has been selected, [00283 More specifically, pushup exerciser 10 is formed of a pair of generally planar board sections 12 and 13 joined along a board section junction 14 in the manner described below in Figures 5 and 6. Suffice it to note here that board section junction 14 provides a fixed attachment which allows board sections 12 and 13 to perform as a single extended generally rigid board 11. Board section 12 defines a generally planar top surface 22 which in turn defines a plurality of post receptacles 50 through 65 therein. Similarly, board section 13 includes a generally planar top surface 23 which in turn defines a plurality of post receptacles 70 through 85. It will be noted that post receptacles 70 through 85 are arranged in a pattern which forms a mirror image of the pattern by which post receptacles 50 through 65 are formed in surface 22 of board section 12. Each of post receptacles 50 through 65 formed on board section 12 and post receptacles 70 through 85 formed on board section 13 comprise generally cylindrical closed end receptacles configured and sized to receive the cooperating cylindrical posts formed on the undersides of handle units 30 and 40 (seen below in Figures 10 and 11). Thus, post receptacles 50 through 65 of board section 12 are arranged in a pattern which facilitates multiple positioning attachments of handle unit 30 upon top surface 22. Correspondingly, post receptacles 70 through 85 of board section 13 are arranged in a mirror image pattern which facilitates multiple positions for attachment of handle unit 40 upon top surface 23 of board section 13.
[0029) In accordance with an important aspect of the present invention, post receptacles 50 through 65 of board section 12 and 70 through 85 of board section 13 are generally arranged in pairs with each pair defining a selected handle unit position upon board 11. In further accordance with an important aspect of the present invention, each pair of post receptacles which define a selectable handle unit position are joined by a color indicia. Each color indicia extends between the pair of post receptacles and which defines a color selected in accordance with a predetermined position code. Accordingly, top surface 22 includes a color indicia 90 extending between post receptacles 50 and 54. Similarly, a color indicia 91 extends between post receptacles 51 and 55 while color indicia 92 extends between post receptacles 52 and 56. A
color indicia 93 extends between post receptacles 53 and 56. A color indicia 94 extends between post receptacles 56 and 57 while a color indicia 97 extends between post receptacles 57 and 61 (partially obscured by handle unit 30). Continuing, a color indicia 95 extends between post receptacles 58 and 59 while a color indicia 96 extends between post receptacles 59 and 60. A
color indicia 98 extends between post receptacles 58 and 63 while a color indicia 99 extends between post receptacles 62 and 63. A color indicia 100 extends between post receptacles 59 and 62 while a color indicia 101 extends between post receptacles 64 and 65.

8 [00301 In a corresponding fashion, a color indicia 110 extends between post receptacles 70 and 74 of board section 13 while a color indicia 1.11 extends between post receptacles 71 and 75.
Similarly, a color indicia 112 extends between post receptacles 72 and 76 while a color indicia 113 extends between post receptacles 73 and 76 and a color indicia 114 extends between post receptacles 76 and 77 (obscured by handle 40). A color indicia 117 extends between post receptacles 77 and 81 (partially obscured by handle unit 40). A color indicia 115 extends between post receptacles 78 and 79 while a color indicia 116 extends between post receptacles 79 and 80. Finally, a color indicia 118 extends between post receptacles 78 and 83 while a color indicia 119 extends between. post receptacles 82 and 83 and a color indicia 120 extends between post receptacles 79 and 84 and a color indicia 121 extends between post receptacles 84 and 85.
[0031] Board section 12 further includes a downwardly extending sidewall 24 while board section 13 further includes a downwardly extending sidewall 25. Sidewalls 24 and 25 extend about the entire periphery of board sections 12 and 13 respectively and are joined along board section junction 14 to form a rigid self-supporting member for board 11. In the preferred fabrication of the present invention, sidewalls 24 and 25 are sufficient to provide depth for post receptacles 50 through 65 and 70 through 85. The fabrication of sidewalls 24 and 25 and their relationship to post receptacles 50 through 65 and 70 through 85 is set forth below in Figure 9 in greater detail. However, suffice it to note here that sidewalls 24 and 25 support top surfaces 22 and 23 respectively above the surface upon which board 11 is rested to maintain clearance between post receptacles 50 through 65 and 70 through 85 above the supporting floor or surface upon which board 11 is rested. In the preferred fabrication of the present invention, board sections 12 and 13 are fabricated as integrally formed molded plastic units which, when joined along board section junction 14 in the manner shown in Figures 5 and 6 and described below,

9 form board 11 into an elongated rigid single exercise board. The fabrication of board 11 in separatable board sections 12 and 13 set forth below in Figures 5 through 8 facilitate convenient separations of board sections 12 and 13 for easy storage and transport.
[0032) Figure 2 sets forth a top plan view of pushup exerciser 10 showing board sections 12 and 13 joined along board section junction 14 to form a rigid board 11.
Figure 2 also shows handle units 30 and 40 positioned upon board sections 12 and 13 respectively.
Thus, Figure 2 shows a top plan view of board 11 and handle units 30 and 40 in an exemplary configuration for the execution of the pushup exercise.
100331 More specifically, pushup exerciser 10 is formed of a pair of generally planar board sections 12 and 13 joined along a board section junction 14 in the manner described below in Figures 5 and 6. Suffice it to note here that board section junction 14 provides a fixed attachment which allows board sections 12 and 13 to perform as a single extended generally rigid board 11. Board section 12 defines a generally planar top surface 22 which in turn defines a plurality of post receptacles 50 through 65 therein. Similarly, board section 13 includes a generally planar top surface 23 which in turn defines a plurality of post receptacles 70 th.rough 85. It will be noted that post receptacles 70 through 85 are arranged in a pattern which forms a mirror image of the pattern by which post receptacles 50 through 65 are formed in surface 22 of board section 12. Each of post receptacles 50 through 65 formed on board section 12 and post receptacles 70 through 83 formed on board section 13 comprise generally cylindrical closed end receptacles configured and sized to receive the cooperating cylindrical posts formed on the undersides of handle units 30 and 40 (seen below in Figures 10 and 11). Thus, post receptacles 50 through 65 of board section 12 we arranged in a pattern which facilitates multiple positioning attachments of handle unit 30 upon top surface 22. Correspondingly, post receptacles 70 through 85 of board section 13 arc arranged in a mirror image pattern which facilitates multiple positions for attachment of handle unit 40 upon top surface 23 of board section 13.
10034] in accordance with an important aspect of the present invention, post receptacles 50 through 65 of board section 12 and 70 through 85 of board section 13 arc generally arranged in pairs with each pair defining a selected handle unit position upon board 11.
In further accordance with an important aspect of the present invention, each pair of post receptacles which define a selectable handle unit position are joined by a color indicia. Each color indicia extends between the pair of post receptacles and defines a color selected in accordance with a predetermined position code. Accordingly, top surface 22 includes a color indicia 90 extending between post receptacles 50 and 54. Similarly, a color indicia 91 extends between post receptacles 51 and 55 while color indicia 92 extends between post receptacles 52 and 56. A
color indicia 93 extends between post receptacles 53 and 56. A color indicia 94 extends between post receptacles 56 and 57 while a color indicia 97 extends between post receptacles 57 and 61 (partially obscured by handle unit 30). Continuing, a color indicia 95 extends between post receptacles 58 and 59 while a color indicia 96 extends between post receptacles 59 and 60. A
color indicia 98 extends between post receptacles 58 and 63 while a color indicia 99 extends between post receptacles 62 and 63. A color indicia 100 extends between post receptacles 59 and 62 while a color indicia 101 extends between post receptacles 64 and 65.
100351 In a corresponding fashion, a color indicia 110 extends between post receptacles 70 and 74 of board section 13 while a color indicia 111 extends between post receptacles 71 and ?S.
Similarly, a color indicia 112 extends between post receptacles 72 and '76 while a color indicia 113 extends between post receptacles 73 and 76 and a color indicia 114 extends between post receptacles 76 and 77 (obscured by handle 40). A color indicia 117 extends between post receptacles 77 and 81 (partially obscured by handle unit 40). A color indicia 115 extends between post receptacles 78 and 79 while a color indicia 116 extends between post receptacles 79 and 80. Finally, a color indicia 118 extends between post receptacles 78 and 83 while a color indicia 119 extends between post receptacles 82 and 83 and a color indicia 120 extends between post receptacles 79 and 84 and a color indicia 121 extends between post receptacles 84 and 85.
[00361 As mentioned above, post receptacles 50 through 65 and 70 through 85 are organized and arranged in post receptacle pairs configured to receive handle units 30 and 40 upon top surfaces 22 and 23 respectively at a variety of selectable positions.
Each of the handle unit positions is selected to provide a particular set of benefits for the pushup exercised being performed. For example, the positions of handle unit 30 upon board section 12 identified by color indicia 90, 91, 92 and 93 together with the mirror image positions of handle unit 40 upon board section 13 identified by color indicia 110, 111, 112 and 113 emphasized shoulder muscle development In accordance with an important aspect of the present invention, color indicia 90, 91, 92 and 93 as well as color indicia 110, I 1 1 , 112 and 113 define a common color (in this case red). This common color provides easily understood and observed association of the shoulder muscle emphasizing handle unit positions_ [0037] In further accordance with the invention, it will be noted that handle units 30 and 40 are fixed as to location and angular position by the pair of post on each handle unit (seen in Figures 10 and 11) and the post receptacle pair receiving them. Thus, the location and angular position of the handle units are securely established and maintained at the selected handle unit positions.
100381 In a similar manner, the handle unit positions of handle unit 30 upon board section 12 identified by color indicia 94,95 and 97 as well as the handle unit positions of handle unit 40 upon board section 13 identified by color indicia 114, 115 and 117 emphasize chest muscle development. In accordance with the above-mentioned aspect of the present invention, color indicia 94, 95 and 97 as well as color indicia 114, 115 and 117 define a common color (in this case blue). Once again this common color provide easily understood and observed association of the chest muscle emphasis handle unit positions.
[00391 In further similarity, the handle positions of handle unit 30 upon board section 12 identified by color indicia 96, 98 and 100 and the positions of handle unit 40 upon board section 13 identified by color indicia 116, 118 and 120 emphasis triceps muscle development. Once again, in accordance with the present invention, color indicia 96, 98 and 100 as well as color indicia 116, 118 and 120 define a common color (in this case green). Once again, this common color provides easily observed and understood association of the triceps muscle emphasis handle unit positions.
100401 Finally, the positions of handle unit 30 upon board section 12 identified by color indicia 99 and 101 and the positions of handle unit 40 upon board section 13 identified by color indicia 119 and 121 emphasize back muscle development. In continued accordance with the present invention color indicia 99, 101, 119 and 121 define a common color (in this case yellow).
Once again, this common color provides easily understood and observed association of the back muscle emphasis handle unit positions of the present invention ptishup exerciser.

10041) Thus, in accordance with the present invention, handle units 30 and 40 are quickly and easily positionable upon board sections 12 and 13 at a selected position and are maintained in a fixed secure location and angular position by the dual post, dual post receptacle cooperation between handle units 30 and 40 the receptacle pairs upon board sections 12 and 13. The color association provided by the color indicia quickly identifies handle unit locations which facilitate or emphasize a chosen muscle group development without resort to any additional materials or directions. It will be apparent to those skilled in the art that while the examples set forth herein utilizes the color red for shoulder emphasis, blue for chest emphasis, green for tricept emphasis and yellow for back muscle emphasis, other colors may be utilized without departing from the spirit and scope of the present invention. The important aspect with respect to this important facet of the present invention is the provision of color coded muscle group indicia having common colors upon board 11 together with the secure location and angular positioning provided by the dual post configuration of the handle units and post receptacle pairs.
100421 Figure 3 sets forth an enlarged partial perspective view of pushup exerciser 10 showing handle units 30 and 40. As described above, pushup exerciser 10 includes a board 11 having a board section 13 within which a plurality of post receptacle pairs are formed. As is also described above, board section 13 defines a generally planar top surface 23 having a plurality of color indicia formed between selected pairs of post receptacles. In Figure 3, board section 13 shows post receptacles 76, 79, 80, 82, 83, 84 and 85. Board section 13 also defines post receptacles 77 and 81 which are obscured by handle unit 40. Color indicia 112, 113, 114, 116, 117, 119 and 121 are also formed upon surface 23 of board section 13.

[00431 Figure 3 also shows a perspective underside view of handle unit 30.
It will be understood by those skilled in the art that handle unit 30 and 40 are identical and that the descriptions of handle unit 30 will apply equally well to handle unit 40.
Accordingly, handle unit 30 includes an elongated base 31 defining a rectangular aperture 32 and supporting a pair of generally cylindrical downwardly extending posts 35 and 36. Handle unit 30 further includes a pair of upwardly extending supports 33 and 34 positioned at opposed ends of base 31. A
generally cylindrical grip bar 37 extends between grip supports 33 and 34 and is secured in the manner set forth below in Figure 12. Grip bar 37 further supports a handle grip 38 preferably formed of a resilient soft material such as foam rubber, foam plastic or the like.
[00441 With handle unit 40 positioned as shown in Figure 3, it will be noted that a portion of color indicia 117 upon which handle unit 40 is attached is visible through the aperture formed in the base of the handle unit. This provides assistance in positioning handle units 30 and 40 at the desired location and within the desired color indicia group during exercise activities.
[00451 Figure 4 sets forth a top plan view of board 11 which, as mentioned above, comprises board sections 12 and 13 joined along a board section junction 14.
As is also mentioned above, board section 12 defines a top surface 22 having a plurality of post receptacles 50 through 65 formed therein. As is also described above, board section 13 defines a top surface 23 having a plurality of post receptacles 70 through 85 formed therein. For purposes of illustration, Figure 4 omits the above-described color indicia which associate the respective pairs of post receptacles in the above-described manner. Of importance to note in Figure 4 is the increased difficulty which would arise in identifying the pairs of post receptacles upon board II
without the aid of color indicia 90 through 101 and 110 through 121 shown above in Figures 1 and 2. This emphasizes the great advantage to be provided by the present invention color indicia pairing of post receptacles which is provided in the manner set forth above.
In the preferred fabrication of the present invention, board 11 is formed of board sections 12 and 13 to provide an elongated board which may be readily separated to facilitate stacking board sections 12 and 13 one upon the other for a more compact storage and transport. In their preferred fabrication, board sections 12 and 13 are formed of molded plastic or other suitable material which provides the advantageous or low-cost mass-production.
[00461 Figure 5 sets forth a section view of board 11 taken along section lines 5-5 in Figure 4. As described above, board ills formed of board sections 12 and 13 defining respective top surfaces 22 and 23 as well as respective sidewalls 24 and 25. As is also mentioned above, board sections 12 and 13 arc joined along board section junction 14. Of importance to note in Figure 5, is the extension of sidewalls 24 and 25 downwardly from top surfaces 22 and 23 respectively.
Thus, in the preferred fabrication of board 11, sidewalls 24 and 25 are longer than the downward extensions of post receptacles formed in top surfaces 22 and 23. To further strengthen board 11 and provide greater support for handle units 30 and 40 during pushup exercise, board 11 defines a plurality of intermediate supporting ribs 40 through 49 spaced beneath board sections 12 and 13. It will be noted that intermediate supporting walls 40 through 49 extend downwardly from top surfaces 22 and 23 by a distance equal to the downward extensions of sidewalls 24 and 25.
As a result, the total weight of the user is distributed between sidewalls 24 and 25 together with intermediate supporting walls 40 through 49 to provide significant rigidity and strength for board 11.

[0047] Figure 6 sets forth a partial section view of board 11 showing board section junction 14 in enlarged detail, More specifically, board section 12 defines a sidewall 24 and a top surface 22 as described above. As is also described above, board section 13 defines a sidewall 25 and a top surface 23. Board section junction 14 includes a generally U-shaped upwardly open channel wall 26 formed at the lower end of sidewall 25 of board section 13. Board section junction 14 further includes a wall flange 27 formed in sidewall 24 of board section 12.
Of importance to note is the formation of an elongated notch 28 formed in wall flange 27. Notch 28 facilitates the insertion of wall flange 27 into channel wall 26 while maintaining the support surface contact of sidewalls 24 and 25. The extension of wall flange 27 into channel wall 26 secures the position of board sections 12 and 13 and forms board section junction 14. This secure attachment resists any separation of board sections 12 and 13 during exercise activities. When the user desires to separate board segments 12 and 13 the user simply forces board section 12 upwardly while forcing board section 13 downwardly which withdraws wall flange 27 from channel wall 26.
Once separated, board sections 12 and 13 may be stacked for compact storage and/or transport.
[0048] Figure 7 sets forth a perspective assembly view of board sections 12 and 13 in which the board sections are separated from each other. As described above, board section 12 defines a top surface 22 within which a plurality of post receptacles 50 through 65 are formed.
As is also described above, board section 12 includes a downwardly extending sidewall 24.
Sidewall 24 includes a portion defining a wall flange 27 having a notch 28 formed therein.
100491 Board section 13 also described above includes a top surface 23 having a plurality of post receptacles 70 through 85 formed therein. Board section 13 further includes a downwardly extending sidewall 25 having a channel wall 26 formed along one portion thereof Channel wall 26 defines an upwardly open generally U-shaped channel which receives wall flange 27 of board section 12 in the manner shown in Figure 6.
100501 Figure 8 sets forth a partial perspective view of board section 13 having sidewall 25 and top surface 23. Of importance to note in Figure 8 is the structure of upwardly open U-shaped channel wall 26.

Handle unit 30 further includes a resilient handle grip 38 which, as mentioned above, is preferably formed of a resilient material such as foam rubber or foam plastic or other suitable easily gripped material.
100551 As mentioned above, handle units 30 and 40 are identical in fabrication.
Accordingly, the descriptions and figures set forth above which illustrate and describe the structure of handle unit 30 will be understood to apply equally well and be equally descriptive of handle unit 40.
[00561 Figures 13 through 15 set forth an alternate embodiment of the present invention in which handle units 30 and 40 are replaced or supplemented by a handle unit constructed to utilize an alternative apparatus for securing, locating and angularly fixing the position of the handles upon the board portions of the present invention pushup exerciser. In essence, the embodiment set forth in Figures 13 through 15 replaces the pair of downwardly extending posts formed in handle units 30 and 40 (seen in Figures 10 through 12) with a single fasted posts.
100571 More specifically, Figure 13 sets forth a side elevation view of a handle unit constructed in accordance with an alternate embodiment of the present invention and generally referenced by numeral 130. Handle unit 130 includes a generally rectangular frame 131 having a base portion 132 which in turn provides a bottom surface 133. Base 132 supports a downwardly extending faceted post 134. Post 134 is faceted with to cooperate with a faceted post receptacle (receptacle 145 shown in Figure 14 receptacle 155 shown in Figure 15). The fitceting of post 134 and cooperating faceted receptacles 145 and 155 provide the angular fixing of the position of h.suiclie 130 utilized in the present invention pushup exerciser. Handle unit 130 further includes a resilient grip 135 formed upon the upper portion of frame 131. Grip 135 is preferably formed of a suitable resilient soft material such as foam rubber or foam plastic.
Alternatively, grip 135 may be fabricated of a suitable leather or other material, [00581 Figure 14 sets forth a partial top view of a board section 140 which is fabricated in general accordance with board sections 12 and 13 set forth above. Thus, board section 140 includes a top surface 141 supporting pairs of generally cylindrical post receptacles such as receptacles 142 and 143. In further similarity to the above.described embodiment, a color indicia 144 extends between post receptacles 142 and 143. Board section 140 differs from board sections 12 and 13 set forth and described above in that it further utilizes a faceted post receptacle 145. Post receptacle 145 is formed to receive faceted post 134 of handle unit 130 (seen in Figure 13). In the example set forth in Figures 13 and 14, faceted post 134 is hexagonal in cross section. Correspondingly, faceted receptacle 145 is also hexagonal in cross section.
However, it will be apparent to those skilled in the art that a different faceted structure may be utilized such as triangular or octagonal or square without departing from the embodiment of the invention shown in Figures 13 through 1$, 100591 In operations, handle unit 130 may be positioned upon board section 140 by inserting faceted post 134 into faceted receptacle 145. It will be apparent that the faceted structure of pest 134 and receptacle 145 provide for a plurality of angularly fixed positions for handle unit 130 upon board section 140, Thus, the very desirable angular fixing of handle unit 130 during the pushup exercise is maintained.
[00601 Figure 15 sets forth a portion of a board section constructed in accordance with the alternative embodiment of the present invention set forth in Figure 13 and 14 above. This further alternate embodiment includes a board section 150 constructed in a similar fashion to board sections 12 and 13 set forth above. Thus, board section 150 includes a top surface 151 within which a pair of post receptacles 152 and 153 are formed. Board section 150 further includes a faceted receptacle 155 surrounded by a color indicia 154. Color indicia 154 performs the same function as the embodiment set forth above in Figures 3 through 3 in that color indicia are utilized to indicate the particular muscle groups to be emphasized.
[00611 Figure 16 sets forth a perspective view of a further alternate embodiment of the present invention pushup exerciser generally referenced by numeral 370. Pushup exerciser 170 is similar to exerciser 10 set forth and described above in that it includes a board comprised of a pair of board sections each defining a plurality of post receptacle pairs for receiving and fixing a pair of handle units on the board surface at selectable positions. Pushup exerciser 170 differs in that board section junction 210 is not straight-line as above , but rather defines a pair of oppositely directed "dove-tail" joints to join the board sections. In all other respects, pushup exerciser 170 is fabricated and operative in the manner described above.
[00621 Thus, pushup exerciser 170 includes board sections 171 and 172 joined at a board section junction 210. Board section 171 defines a plurality of post receptacles 191 through 206.
while board section 172 defines a plurality of post receptacles 175 through 190. Post receptacles 191 through 206 and 175 through 190 arc arranged in pairs to receive handle, units 173 and 174.
Board sections 171 and 172 also support color indicia in the manner shown above in Figure 1 which are omitted from the figure to avoid cluttering Figure 16.
[00631 Figure 17 sets forth an assembly view of board sections 171 and 172.
As mentioned above, pushup exerciser 170 includes board sections 171 and 172 joined at a board section junction 210. Board section 171 defines a plurality of post receptacles 191 through 206. while board section 172 defines a plurality of post receptacles 175 through 190.
Post receptacles 191 through 206 and 175 through 190 are arranged in pairs to receive handle units 173 and 174. As is also mentioned above, board sections 171 and 172 also support color indicia in the manner shown above in Figure 1 which are omitted from the figure to avoid cluttering Figure / 7.
100641 Board section 171 defines a junction wall 211 having a dove-tail notch 212 and a dove-tail extension 213 formed therein. Correspondingly, board section 172 defines a junction wall 215 having a dove-tail notch 216 and a dove-tail extension 217 formed therein. Board sections 171 and 172 are joined by inserting dove-tail extensions 213 and 217 into dove-tail notches 216 and 212 respectively. This provides a secure attachment between board sections 171 and 172 during use which may be separated for storage and transport as needed.
po6si What has been shown is a novel pushup exerciser having multiple hand positioning handle units which are selectively attachable to a supporting board for exercise of different muscle groups during pushup exercise. The invention shown includes a supporting board formed of a pair of board sections joined along a board section junction to form a rigid board structure.
The board sections may be separated to facilitate compact and convenient storage and transport.
The pushup exerciser includes a plurality of post receptaclea disposed upon the supporting board in paired arrangement each paired arrangement defining a position, location and angle orientation of a handle unit received within. Coordinating color indicia are provided in association with each post receptacle pair to provide easy identification of muscle group emphasis for each receptacle pair and handle unit location.

[00661 While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
