BACKGROUND OF THE INVENTION1. Technical Field
This invention relates generally to equipment used for mountain climbing and rock climbing. More particularly, the invention relates to climbing walls and the artificial rocks used thereon. Specifically, the invention relates to such an artificial rock having a recess formed therein for receiving a safety device such as a piton or a camming device.
2. Background Information
Mountain and rock climbing over the last several decades have become an increasingly widespread sport. The sport is broadly divided into free climbing and climbing with ropes and related equipment. Due to the popularity of the sport, the practice of rock climbing indoors has become widespread with the advent of climbing walls using artificially formed gripping surfaces, such as artificial rocks which are attached to walls formed of any suitable material. Such artificial rocks have been used broadly within the free climbing aspect of the sport although safety ropes suspended from above are typically attached to climbers as they practice this free climbing style. However, the other aspect of climbing has yet to be represented in the artificial industry, that is, wherein climbers use ropes and related equipment to suspend themselves or protect themselves from falling by inserting a structure known as a piton or other safety device into a crevice of a rock. Thus, there is a need to provide a climbing wall on which climbers may practice their trade using pitons, ropes and related equipment.
BRIEF SUMMARY OF THE INVENTIONThe present invention provides an artificial rock for use with a climbing wall, the rock comprising a first rigid wall having a first lateral surface; a second rigid wall which is adjacent and fixed with respect to the first wall and which has a second lateral surface which generally faces the first lateral surface; wherein the rock has a back adapted to face the climbing wall when mounted thereon; wherein the first and second lateral surfaces define therebetween a forward opening recess adapted to receive a safety device therein for supporting climbing equipment; and wherein the rock has sufficient strength to support a weight of a climber.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
Similar numbers refer to similar parts throughout the specification.
DETAILED DESCRIPTION OF THE INVENTION A first embodiment of the artificial rock of the present invention is indicated generally at 10 in
In accordance with the invention and with reference to
Recess 20 extends in a continuous manner from top 22 to bottom 24 and thus is upwardly opening at top 22 and downwardly opening at bottom 24. Each of rock 10 and recess 20 has a length which is the same as the other, as represented at L in
Rock 10 may be thought of as including a pair of laterally spaced and relatively thick walls 50A and 50B which are separated by recess 20 and respectively include first and second lateral surfaces 42 and 44, with walls 50A and 50B joined by a rear bridge 52 which includes rear surface 46. Rear bridge 52 has an upper thickness T2 (
In use and with reference to
To use support equipment 16 with rock 10, piton 56 is inserted into recess 20 and moves downwardly as indicated at arrow C in order to wedge in between first and second lateral surfaces 42 and 44 whereby support equipment 16 supported by rock 10 with piton 56 engaging surfaces 42 and 44. Although not required, it is preferred that lateral surfaces 42 and 44 are configured to mate with downwardly and inwardly tapered opposed side surfaces 68 and 70 of piton 56. With piton 56 firmly wedged or seated within recess 20, cable 58 hangs downwardly therefrom and passes through a lower portion of recess 20 at bottom 24 thereof, the lower portion having depth D1 (

In accordance with the invention and with continued reference to
Recess 104 includes three sections which are vertically oriented with respect to one another. In particular, recess 104 includes a tapered upper section 118, a vertically parallel intermediate section 120 and a tapered lower section 122. More particularly, upper section 118 has first and second lateral surfaces 124 and 126 which taper downwardly and inwardly with respect to a first vertical plane 128 disposed therebetween. Rock 100 is bilaterally symmetrical about plane 128. Lateral surfaces 124 and 126 extend from top 106 of rock 100 downwardly to respective first and second intersection locations 130 and 132 which define the bottom of upper section 118 and the top of intermediate section 120. Upper section 118 has a vertical height HI extending from top 106 of rock 100 to intersection locations 130 and 132.
Intermediate section 120 has first and second opposed lateral surfaces 134 and 136 which are parallel to one another and vertical plane 128. First and second lateral surfaces 134 and 136 of intermediate section 120 define therebetween a width W5. Lateral surfaces 134 and 136 extend downwardly respectively from first and second intersection locations 130 and 132 to a lower end of intermediate section 120 at first and second intersection locations 138 and 140 which define the bottom of intermediate section 120 and the top of lower section 122 of recess 104. Intermediate section 120 has a vertical height H2 defined between intersection locations 130 and 132 at the top of section 120 to intersection locations 138 and 140 at the bottom of intermediate section 120.
Tapered lower section 122 of recess 104 has first and second opposed lateral surfaces 142 and 144 which taper inwardly and downwardly with respect to plane 128 from intersection locations 138 and 140 to bottom 108 of rock 100. Lower section 122 has a vertical height H3 defined between intersection locations 138 and 140 at the top thereof to bottom 108 of rock 100. Although the heights HI, H2 and H3 may vary, they are all the same in the present embodiment so that upper section 118 extends from top 106 of rock 100 one-third of the way down to bottom 108, intermediate section 120 extends from one-third of the way down to two-thirds of the way down to bottom 108 and lower section 122 extends from two-thirds of the way down to bottom 108 of rock 100. Thus, each of sections 118, 120 and 122 represent a respective one-third of the height of rock 100.
It is further noted that the respective lateral surfaces of upper section 118 and lower section 122 are substantially flat and are angled in a manner similar to lateral surfaces 42 and 44 of artificial rock 10. Thus, as shown in
Rock 100 further includes a rear surface 146 which bounds the rear of recess 104. Rear surface 146 is substantially flat and tapers downwardly and forwardly with respect to a second vertical plane 148 perpendicular to first vertical plane 128, as described with regard to rear surface 46 of recess 20 of rock 10, as indicated at C in
Rock 100 may be thought of as having a pair of lateral walls 150A and 150B analogous to walls 50A and 50B of rock 10. Thus, lateral walls 150A and 150B are spaced from one another and separated by recess 104 of rock 100. Lateral wall 150A includes lateral surfaces 124, 134 and 142 of respective sections 118, 120 and 122 of recess 104. Lateral wall 150B likewise includes lateral surfaces 126, 136 and 144 of recess 104. Lateral walls 150A and 150B each define a counterbore mounting hole 154 analogous to mounting holes 36 and having the same configuration. Lateral walls 150A and 150B are joined by a rear bridge 152 which includes rear surface 146. Similar to rear bridge 52 of rock 10, rear bridge 152 is thicker adjacent bottom 108 of rock 100 than it is adjacent top 106 of rock 100. One distinction of recess 104 with respect to recess 20 of rock 10 is that recess 104 at bottom 108 of rock 100 is deeper than is recess 20 adjacent bottom 24 of rock 10. This distinction relates to the use of camming device 102, which has a greater depth dimension which passes through the opening of recess 104 adjacent bottom 108 of rock 100. Thus, this increased depth dimension accommodates the depth of camming device 102 sufficiently to help prevent device 102 from pulling forward and out of recess 104, as described with regard to piton 56 and recess 20 of rock 10.
In use, rock 100 is mounted on climbing wall 12 in the same manner as described with reference to rock 10. Upper section 118 and lower section 122 of recess 104 are configured for use with passive safety devices such as a piton as described with reference to rock 10. However, as previously noted, rock 100 is also configured for use with active safety devices such as camming device 102. With reference to
Camming devices 102 includes a frame 158 with a plurality of camming members 160 pivotally mounted thereon adjacent an end of frame 158 whereby members 160 move as indicated by Arrows D in
To use support equipment 156 with rock 100, camming device 102 is operated to move camming members 160 toward the closed position so that camming members 160 may be inserted into recess 104 within intermediate section 120 thereof. More particularly, a climber will position a thumb on thumb grip 162 and a finger or fingers on finger grip 164 and squeeze to move camming members 160 toward the closed position. Once camming members 160 are inserted within intermediate section 120 of recess 104, the climber will release his or her grip on thumb grip 162 and finger grip 164 to allow camming members 160 to move toward the open position due to the spring bias thereof. Movement of camming members 160 toward the open position engages the respective camming members 160 against lateral surfaces 134 and 136 of intermediate section 120 to hold camming device 102 in place within recess 104. As is well known in the art, downward force on frame 158 of camming device 102 is translated to a camming force which moves or attempts to move camming members 160 toward the open position, thereby creating a forceful engagement between camming members 160 and lateral surfaces 134 and 136.
Device 102 is disposed within recess 104 so that U-shaped support 168 of frame 158 and actuator cables 166 pass through lower section 122 and out of recess 104 at bottom 108 of rock 100. Thumb grip 162 and finger grip 164 are disposed below bottom 108 of rock 100 with finger grip 164 spaced downwardly therefrom sufficiently to allow the climber to insert a finger in order to operate device 102 from below rock 10. As previously noted, depth D2 of recess 104 adjacent bottom 108 of rock 100 is greater than that of recess 20 of rock 10 in order to accommodate frame 158 and actuator cables 166 of device 102. As previously noted, intermediate section 120 has a width W5 (
Artificial rock 200 (
It was noted with respect to rock 100 that thumb grip 162 and finger grip 164 were disposed below bottom 108 of rock 100 with finger grip 164 spaced downwardly therefrom sufficiently to allow the climber to insert a finger in order to operate device 102 from below rock 10. However, this is not a requirement, as shown with rock 200 in
Artificial rock 300 is similar to rock 200 except that rock 300 defines a recess 302 which is laterally bound by first and second lateral surfaces 304 and 306 which are substantially flat and vertical and parallel to one another and vertical plane 128. A substantially flat and vertical rear surface 308 bounds recess 302 rearwardly in the same manner as rear surface 204 bounds recess 202 of rock 200. Artificial rock 300 includes a pair of spaced lateral walls 350A and 350B analogous to walls 250A and 250B of rock 200. Lateral walls 350A and 350B respectively include lateral surfaces 304 and 306. Thus, walls 350A and 350B vary from walls 250A and 250B with respect to the different configuration of recesses 302 and 202 respectively.
Recess 302 thus has a width W5 (
Thus, the present invention provides several embodiments of an artificial rock which may be used as a standard artificial rock on a climbing wall and also with climbing support equipment which provides a safety feature for the climber and allows the climber to practice with said equipment. Each of the artificial rocks of the present invention is thus configured to support the weight of the climber using the rock, whether the climber is placing his or her weight on the rock with a hand or foot thereon, or via the use of safety devices like those described herein. While smaller climbers may of course be supported by rocks of comparatively lesser strength, the rocks of the present invention should easily support a weight of 200 pounds without breaking or pulling loose from the climbing wall. More typically, the present rocks will support 300, 400, 500 pounds and often much more in order to ensure safety of the climber. The rocks also are configured to support such weights when applied via gravity as a sudden downward force via the safety devices within the recess of a respective rock, as is the case when the climber falls and is caught by the safety equipment suspended from the rock.
It will be evident to one skilled in the art that a variety of changes may be made which are within the scope of the present invention. For example, the overall shape of the body of the artificial rock may be varied substantially without departing from the scope of the invention. Thus, for instance, the artificial rock may have a body which is shaped more like a standard artificial rock used with climbing walls to provide different gripping surfaces for the hands and feet of the climber while also providing the recess therein for use with a piton. In addition, the recess formed in the artificial rock may have a variety of configurations. The surfaces which bound the recess of the embodiment shown in the drawings are all substantially flat and with regard to the tapered recess or sections thereof provide a constant taper, although this is not required. Thus, for instance, lateral surfaces 42 and 44 and rear surface 46 may have angles which vary along the length of the recess from top to bottom. This would include such surfaces being angled or being curved in a convex manner while moving downwardly along the recess. Because a piton seated within the recess may or may not come into contact with rear surface 46 or a surface analogous thereto, the particular angle at which the rear surface tapers is of less concern than that of the lateral surfaces bounding the recess. Nonetheless, as previously noted, the rear bridge of artificial rock 10 must have sufficient structural strength in order to support a climber utilizing rock 10.
It will be appreciated that with artificial rocks such as rocks 100 and 200 which include a tapered section and a parallel-side section that the tapered and parallel sections may be disposed at various levels within the artificial rock. Thus, an artificial rock may have a parallel section at the top and a tapered section at the bottom or vice versa. In addition, such a rock may include any number of tapered sections and parallel sections which are suitable to the purpose of supporting a safety device therein.
The various recesses may also be formed in a manner to help prevent a piton or other safety device from becoming dislodged therefrom through the forward opening portion of the recess. Thus, for instance, the lateral surfaces bounding the recess may angle inwardly and forwardly in a manner that would tend to move the safety device in a rearward manner when seated in the recess. In addition, lips may be formed which extend inwardly respectively from the lateral walls (such as 50A and 50B) along the front of the rock to provide a barrier which would prevent a safety device from sliding forward and out of the recess. Other variations will be evident to one skilled in the art.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of the invention is an example and the invention is not limited to the exact details shown or described.
