DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(10) Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

(11) Unless the context clearly requires otherwise, throughout the description and the claims, the words comprise, comprising, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of including, but not limited to. Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words herein, above, below and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word or in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word each is used to refer to an element that was previously introduced as being at least one in number, the word each does not necessarily imply a plurality of the elements, but can also mean a singular element.

(12) FIGS. 1-2 illustrate an exercise apparatus 10 for use by a person 20 on a support surface 15, such as a floor. A foot docking station 30 comprises a rigid, preferably metallic base plate 40 pivotally fixed to a rigid, preferably metallic back plate 50 at a hinge 60. The back plate 50 includes a central pivot 55 rotationally fixed with a bottom side 72 of a rigid, preferably metallic foot plate 70.

(13) The foot plate 70 has a shin engagement mechanism 80 extending away from a top side 78 thereof for engaging the shins 22 of the person 20 while the person's feet 24 contact the top side 78 of the foot plate 70 or a cushion 79 affixed thereto. The shin engagement mechanism 80 includes a pair of cushioned, arched shin pads 400 projecting laterally away therefrom. Optionally the arched shin pads 400 may be fixed on a shin pad trolley 84 that is adjustably moved closer or farther away from the foot plate 70 with a retention pin 440, or other similar mechanism for moving the arched shin pads 400 up and down with respect to the foot plate 70.

(14) Preferably the base plate 40 and foot plate 70 further include a rotational locking mechanism 90 adapted for selectively locking the relative rotational position between the back plate 40 and the foot plate 70. Such a rotational locking mechanism 90 may include, for example, a plurality of locking apertures 92 each arranged a common distance D from the central pivot 55 and a release pin arrangement 94 and pin 96 arrangement fixed with the foot plate 72 and biased to urge the pin 96 into one of the locking apertures 92. As such, the user 20 can pull the release pin 96 out of the locking aperture 92 to allow the foot plate 70 to rotate about the pivot 55 with respect to the back plate 50. The release pin arrangement 94 may be set in a fully retracted position (not shown) if desired so that the foot plate 70 freely rotates on the back plate 50 during exercising.

(15) Preferably the base plate 40 further includes a weight rod 49 (FIG. 1) projecting upwardly therefrom and adapted to receive at least one annular weight (not shown) thereon. Alternately, a door or other heavy item (not shown) may be engaged with the weight rod 49 or base plate 40 to maintain the base plate 40 on the support surface 15.

(16) Preferably the exercise apparatus 10 further includes a lower bench 110 (FIGS. 3 and 4). The lower bench comprises a rigid, preferably metallic, elongated lower shaft 120 having a proximal end 122 and a distal end 128 adapted for engaging the foot docking station 30 with at a plurality of the second pin receivers 430. When the foot docking station 30 is engaged with the lower bench 110, the base plate 40 is removed and replaced with the lower shaft 120 (FIG. 4).

(17) A distal leg 130 is fixed with the distal end 128 of the lower shaft 120 at a rotational leg mount 140. The distal leg 130 is positionable between a retracted position 150 (FIG. 6) aligned with and adjacent to the lower shaft 120, and a plurality of extended positions 160 (FIGS. 3-5, 7 and 8). In such an embodiment, the rotational leg mount 140 includes a rotational lock 142 adapted for selective locking of the relative rotational position of the distal leg 130 and the lower shaft 120. The distal leg 130 terminates at a distal end 138 thereof with at least one surface grip 139.

(18) Preferably the distal leg 130 includes a single T-shaped leg 330 having a main shaft 334 and two laterally projecting shafts 336. The rotational leg mount 140 includes an axle 144 (FIG. 5) traversing the proximal end 132 of the distal leg 130. The rotational lock 142 includes at least one locking plate 145 through which a pin 146 can engage any one of a plurality of pin stops 147 to selectively lock the relative rotational position of the distal leg 130 and the lower shaft 120.

(19) Preferably the proximal end 122 of the lower shaft 120 of the lower bench 110 further includes a receiver 180 for engaging an upper bench 190 (FIGS. 7-13C). A rigid, preferably metallic, elongated upper shaft 200 has a distal end 208 adapted for engaging the receiver 180 of the lower shaft 120, and a proximal end 202. A proximal leg 210 is fixed with the proximal end 202 of the upper shaft 200 at another rotational leg mount 140 at a proximal end 212 thereof, identically to that of the distal leg 130 except oriented 180-degrees such that the proximal leg 210 may extend beyond the proximal end 202 of the upper shaft 200 when in a most extreme extended position 160. The proximal leg 210 terminates at a distal end 218 thereof with at least one of the surface grips 139.

(20) In such an embodiment, the distal end 208 of the upper shaft 200 and the receiver 180 of the lower shaft 120 include a second pin locking mechanism 370 (FIG. 7), such that a locking pin 376 may be used to selectively lock the proximal end 122 of the lower shaft 120 to the distal end 208 of the upper shaft 200.

(21) Preferably a pair of wheels 310 (FIGS. 5 and 6) extends past the proximal end 202 of the upper shaft 200. The distal end 128 of the lower shaft 120 includes a pulling handle 320. As such, with the proximal and distal legs 210,130 each in their retracted positions 150, the pulling handle 320 may be lifted and pulled to roll the apparatus 10 along the support surface 15 upon the third pair of wheels 310.

(22) An auxiliary bench 460 (FIGS. 5-7) may be attached to the upper and lower benches 190,110 by removing the foot docking station 30. The auxiliary bench 460 may be selectively attached to the upper and lower benches 190,110 at a pair of mechanical fastener pins 465. As such, by positioning the proximal and distal legs 210,130 in their various positions, the auxiliary bench 460 may be reclined, inclined, or level. An optional pivotal seat section 470 may be included at the distal end of the auxiliary bench 360 and separably inclined with respect to the auxiliary bench 460 (FIG. 7), or rotated to become aligned with the auxiliary bench 460 (FIG. 6). A bracket and pin mechanism 475 cooperative with the plurality of second pin receivers 430 of the lower shaft 120 is included for selectively positioning the rotation of the seat section 470 with respect to the auxiliary bench 460.

(23) The apparatus 10 may further include a seat 480 fixed with the proximal end 202 of the upper shaft 200 (FIGS. 5 & 8), as well as a pair of rigid hand grips 490 and a pair of knee supports 500 for performing various leg exercises while being able to sit on the seat 480 and hold onto the apparatus 10 manually at the hand grips 490.
