DETAILED DESCRIPTION

(14) Referring first to FIGS. 1-4, a climbing exercise apparatus is generally identified by the reference numeral 100. The apparatus 100 may include a base 110. A generally vertically extending stanchion 112 may be fixedly secured to the base 110. A brace member 113 having distal ends fixedly secure to the base 110 and the stanchion 112 may angularly support the stanchion 112. The stanchion 112 may extend upwardly from the base 110 an angle of about fifteen (15) degrees from vertical.

(15) Referring now specifically to FIG. 2, the stanchion 112 may include spaced apart substantially parallel stanchion members 114 and 115. The lower ends of the stanchion 112 may be fixedly secured to the base 110 and the upper ends thereof connected by a bridge member 116 (shown in FIG. 1) to maintain the spacing between the stanchion members 114, 115. The stanchion members 114, 115 may include a pair of longitudinal stanchion races 117 and 118, respectively, in facing relationship to one another defining a gap 120 between the stanchion members 114, 115.

(16) The climbing exercise apparatus 100 may include arm carriages 122 and 124 linearly constrained to move along the stanchion races 117, 118 in the gap 120 between the stanchion members 114, 115. Hand grips 126 and 128 may be connected to the arm carriages 122, 124, respectively. Rollers or low friction material and the like may be utilized to facilitate the linearly constrained movement of the arm carriages 122, 124 along the stanchion races 117, 118.

(17) Foot support members 132 and 134 may extend downwardly from the arm carriages 122, 124, respectively (see FIG. 6). The foot support members 132, 134 may be fixedly secured to the arm carriages 122, 124. The foot support members 132, 134 may define right-angle structures comprising elongated vertical legs 133 and transverse legs 135. The transverse legs 135 may extend in opposite directions relative to one another. Through holes 137 and 139 may extend through the the transverse legs 135 of the foot support members 132, 134.

(18) Foot carriages 140 and 142, linearly constrained to move along the stanchion races 117, 118 in the gap 120 between the stanchion members 114, 115, may be coupled to respective arm carriages 122, 124. The foot carriages 140, 142 may include spaced apart through holes 144, 145 and 146 aligned horizontally proximate the upper end 148 of the foot carriages 140, 142. Foot pedals 141 may be secured proximate the lower distal ends of the foot carriages 140, 142, generally in a non-adjustable manner but may be rotatably secured to the foot carriages 140, 142, if preferred.

(19) Means may be provided, such as but without limitation, a cable 150 or roller chain such that opposite and reciprocal motion may occur between arm carriages 122, 124 and foot carriages 140, 142. The user may set the exercise mode of the climbing exercise apparatus 100 to straight climbing or cross climbing and vice versa. To facilitate a change in the climbing mode of the climbing exercise apparatus 100, the foot carriages 140, 142 may be leveled (equal height above the floor) relative to one another, best shown in FIG. 3, so that through holes 139 of the transverse legs 135 of the support members 132, 134 align with the through holes 145 of the foot carriages 140, 142. A temporary alignment pin 152 may be inserted through the aligned holes 139 and 145 to temporarily secure the foot carriages 140, 142 to the foot support members 132, 134. To configure the climbing exercise apparatus 100 for homolateral or straight climbing, lock pins 154 may be inserted through holes 144 of the foot carriages 140, 142 and holes 137 of the transverse legs 135, thereby securing foot carriage 142 to foot support member 132 and foot carriage 140 to foot support member 134, shown in FIG. 4. To configure the climbing exercise apparatus 100 for contralateral or cross climbing, shown in FIG. 5, the lock pins 154 may be inserted through holes 146 of the foot carriages 140, 142 into holes 137 of opposite transverse legs 135, thereby securing foot carriage 140 to foot support 132 and foot carriage 142 to foot support 134.

(20) Referring now to FIGS. 7-9, a second embodiment of a climbing exercise apparatus is generally identified by the reference numeral 200. The climbing exercise apparatus 200 may include a base 210 adapted for resting on a substantially flat surface, such as but without limitation, a floor. A stanchion 212 may be fixedly secured to the base 210. The stanchion 212 may extend generally vertically upward from the base 210. A cross member 214, integrally formed with the stanchion 212 or separately bolted or otherwise secured to the upper end of the stanchion 212, may extend transverse to the longitudinal axis of the stanchion 212. The upper end of the stanchion 212 may define a T-shaped profile where portions of the cross member 214 project from the stanchion 212 in opposite directions.

(21) A pair of guide members 216 and 218 may include upper ends fixedly secured to the upper end of the stanchion 212. The guide members 216, 218 may be spaced apart from one another and may extend substantially parallel to the stanchion 212. The guide members 216, 218 may be fixedly secured to the base 210 spaced from and in front of the stanchion 212.

(22) Arm carriages 220 and 222 may be slidably secured to respective guide members 216, 218. Hand grips 215 and 217 may be connected to the arm carriages 220, 222, respectively. The arm carriages 220, 222 may be linearly constrained to move along the guide members 216, 218 in a generally vertical reciprocal motion. A pair of pulleys 224 and 226 may be rotatably secured to the cross member 214. A larger pulley 228 may be rotatably secured proximate the lower end of the stanchion 212. A cable 230 or roller chain may be utilized to provide reciprocal or oppositional dependent movement of the arm carriages 220, 222. The cable 230 may be routed over the pulleys 224, 226 and the pulley 228. Links 232 projecting from the arm carriages 220, 222 may connect the arm carriages 220, 222 to the cable 230. The ends of the links 232 may be crimped or otherwise secured to the cable 230.

(23) The arm carriages 220, 222 may include a plurality of openings or holes 234 along the length thereof. The position of the hand grips 215, 217 may be adjusted along the arm carriages 220, 222 to accommodate the height of a user by detaching the hand grips 215, 217 from the arm carriages 220, 222 and reattaching them at openings 234 at a different height.

(24) Foot carriages 240 and 242 may be slidably secured to respective guides 216, 218. Foot or pedals 243 may be secured proximate the lower distal ends of the foot carriages 240, 242, generally in a non-adjustable manner but may be rotatably secured to the foot carriages 240, 242, if preferred. A second cable 244 or roller chain may be utilized to provide reciprocal or oppositional dependent movement of the foot carriages 240, 242. The cable 244 may be routed over an intermediate pulley 246 secured to the stanchion 212 and the distal ends thereof secured to respective foot carriages 240, 242.

(25) A contact roller 250 may be secured to an axle 252 which is rotatably secured to the stanchion 212. The roller 250 may engage the large pulley 228. A portion of the cable 230 may be routed over the roller 250. A gear 254 concentric with the roller 250 may be secured to the axle 252. The gear 254 may be in operative engagement with a linear rack with teeth 256 secured to the foot carriages 240, 242.

(26) While preferred embodiments of the invention have been shown and described, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims which follow.
