Definitions

  • the invention is related to the field of exercise devices and more particularly to simulation equipment for sport practice and rock climbing.
  • the present invention provides a simulated climbing wall for a climber to climb up on, comprising: a frame; an articulated wall in the form of a continuous chain structure including a plurality of climbing wall panels hingedly attached, one to the next, in the form of a chain; and suspension means, affixed to the frame, for supporting the articulated wall in such a way that the panels may move downwardly as the climber climbs the articulated wall.
  • a preferred embodiment includes two channel members, each pivotally attached at its upper end to the frame and panels having rollers on their edges the rollers riding within the channel members.
  • Each panel has a removeable ⁇ surface board.
  • the suspension assembly mounted on top of the frame, includes an automotive rear axle assembly with wheels and a brake.
  • the articulated wall may rotate over the wheels in the manner of a belt on a pulley but normally the brake is locked on and the brake prevents movement of the wall surface.
  • a rope attached to the climbers waist releases the brake and the weight of the climber causes the wall surface to descend.
  • the channel members are pivotally adjustable with respect to the frame such as to allow adjustment of the pitch angle of the wall surface and thereby present to the climber a wall surface that is alternatively a steep slope, a vertical wall or an overhang.
  • Figure 1 is a perspective view of the simulated climbing wall
  • Figure 2 is a perspective cut*away view of the simulated climbing wall
  • Figure 3 is a perspective view of one embodiment of the climbing wall panel

  • Figure 10 is a side view of an alternative embodiment of the cantilever frame; wherein the same element is referred to by the same reference numeral throughout the several views.
  • Figure l shows the invention assembled on a frame (11) .
  • An articulated wall structure (12) having flat faced panels (1) is disposed so that it provides a flat simulated climbing wall for the climber to climb up.
  • Figure 2 shows the articulated wall structure (12) and the flat faced panels (1) and rollers (2) disposed so that the rollers ride within facing channels of channel members (3) thereby providing a flat simulated climbing wall face between the channel members.
  • Frame (11) serves as a mount for two pivotally mounted channel members.
  • the two channel members (3) are pivotally mounted on pivots (4) . These pivots allow adjustment of the pitch angle of the climbing wall
  • the weight of the articulated wall structure is supported by a suspension assembly (5) which is mounted within a cradle (6) on top of frame (11) .
  • the suspension assembly includes brakes (not shown), one on each wheel.
  • a three pound weight (7) is supported by a rope (8) which runs over pulleys (10) .
  • FIG. 6 shows the other end of rope (8) , which runs through a system of pulleys (10) attached to a first lever (66) .
  • the first lever is attached via linkage wire (69) to a second lever (67) .
  • the second lever is attached to brake actuating rods (61) which are attached to the brakes.
  • second rope (14) is attached to the three pound weight (7) and runs over pulleys (15) .
  • the other end of rope (14) is attached to a carabiner (9) which may be attached to the climber's waist such that when the climber passes the predetermined height, rope (14) may release the brake.
  • FIG. 3 shows detail of one embodiment of climbing wall panel (1) .
  • the perspective shown is from the inside of the articulated wall structure of Figure 2. If the climbing wall face is considered the front side of the panel, Figure 3 shows the back side.
  • a panel frame (32) contains a surface board (31).
  • each.surface. board is a l'-X 6', 1/2" plywood sheet and the panel frame is made of 1-1/2 inch square steel tubing. Climbing holds may be attached to the face of the panel by a variety of means.
  • Adjacent panels are hinged together on the back of the frame members by four hinges (34) .
  • the two outer hinges have long bolts (35) which serve as hinge pins and also as axles for rollers (2) .
  • bumper blocks (33) in the articulated wall structure assembly serve to keep the panels centered on the suspension assembly.
  • FIG. 4 shows detail of a preferred embodiment of climbing wall panel (1) .
  • the perspective shown is from the inside of the articulated wall structure of Figure 1. If the climbing wall face is considered the front side of the panel, Figure 4 shows the back side.
  • a panel has a first frame (41), a second frame (42) and a surface board (31) attached to the second frame.
  • each surface board is a 1 » X 6*, 1/2" plywood sheet and each frame is made of 1-1/2 inch square* steel tubing. Climbing holds may be attached to the face of the surface board by a variety of means.
  • Adjacent panels are hinged together on the back of the first frame members by four hinges (34) .
  • the two outer hinges have long bolts which serve as hinge pins and also as axles for rollers.
  • the first frames are made of welded square-section steel tubing and are hinged together.
  • the surface boards have a second frame mounted on the reverse side. Each second frame fits inside its corresponding first frame and is secured by spring loaded pins in the ends of the first frames that engage with holes in the second frames.
  • the second frames made of maple or other strong lightweight material, serves the dual function of positioning the panel on the first frame and also stiffening the panel so that it will not bow out under the pull of the climber.
  • a preferred embodiment of the surface board fastening means, a spring-plunger is shown in Figure 5. This consists of a pin (52) , a spring (53) and a ring (54) .
  • Figure 4 shows two spring-loaded pins, one at each end of the second frame. The surface board may be released for removal by pulling either pin. Both pins are accessible on panels that are at the back of the climbing frame, in curtain wall (16) of Figure 1. The panel is accessible from either side and may be removed by one person.
  • Figure 6 shows a top view of the suspension assembly and in particular the braking and damping system.
  • Figure 6 shows two wheels (13) mounted on an automotive rear axle assembly differential unit (60) .
  • the wheels support the weight of the articulated wall structure and allow the articulated wall structure to move down, under the weight of the climber, when the brakes are released.
  • the brakes are normally on and are released when the climber passes a predetermined height on the wall.
  • the rope (14) which is attached to his waist by a carabiner, passing over pulleys (15) becomes taut and lifts the 3 lb. weight (7) . This releases the pressure of the weight (7) from the rope (8) which runs through pulleys (10) and is attached to the first lever (66) .
  • first lever (66) rotates about pivot (65) which via linkage wire (69) causes second lever (67) to release the brake via brake actuating rods (61) .
  • damper (64) which is linked via chain sprocket (62) and chain (63) to the wheels via the automotive rear axle assembly differential unit.
  • a counterweight (68) balances the weight of levers (66) and (67) .
  • Other brake and lever arrangements and other means for supporting the articulated wall and allowing the wall, to move vertically may be used.
  • non-mechanical brakes may be used such as might be provided electro-mechanically by an electric motor.
  • bumper bars serve to keep the panels centered on the suspension assembly.
  • the bumper bars (43) are shown in Figure 4 and are square-section metal tubing members welded onto the back of the first frames. The ends of the bumper bars are cut at an angle of approximately 45 degrees.
  • the bumper bars serve three functions. First, they serve to keep the curtain wall centered on the wheels of the suspension assembly while the climbing wall is in use. Second, they serve to strengthen the first frame. Third, when the frame hinges fold in the course of operation, they limit the degree of folding to an angle of approximately 90 degrees which improves the smoothness of descent of the simulated wall.
  • a cut away top view of a preferred embodiment of the suspension assembly showing the operation of the centering bumpers is shown in Figure 7.
  • Two wheels (13) are mounted on an automotive rear axle assembly differential unit (62) .
  • the wheels support the weight of the articulated wall structure and allow the articulated wall structure to move down, under the weight of the climber, when the brake is released.
  • First frames (41) ride over wheels (13) such that bumper bars (43) maintain the centered alignment of the frames when the simulated climbing wall turns during use.
  • FIG 8. A preferred embodiment of the cantilever frame is shown in Figure 8.
  • the frame which is made of lightweight metal such as aluminum or tubular steel, has a horizontal member (90) .
  • Figure 8 also shows a preferred embodiment of the adjustment mechanism (80) for adjusting the vertical angle of the channel members and climbing surface. It is a very simple arrangement using a drum and cable arrangement. More detail is shown in Figure 9.
  • drums (88) are carried by an axle (83) that runs across the machine between side frames (81) .
  • the axle is positioned behind the curtain wall (15 in Figure 1) .
  • the axle turns in bearings (87) mounted on boxes (92) that may slide towards the front and back on horizontal member (90).
  • the axle is turned by hand wheel (91) .
  • a handwheel is preferred over a crank for safety reasons.
  • drums (88) are mounted between the bearings on the axle. These drums have several turns of cable (89) wound around them. The middle of the cable is attached to the drum. The two free ends of each cable extend to the front and back of the machine where they are firmly attached to the frame and are stretched tight with a turnbuckle. Thus, when the axle is turned by a handwheel at one end, the entire assembly rides forward and backward on the cable.
  • an arm (85) is pivotally attached to the axle at one end and to the channel member by pivot (86) at the other end.
  • the axle carries two wheels (84) , mounted between the arms, which hold the curtain wall well clear of the axle such as to prevent climbing holds attached to the surface board from coming into contact with the axle.
  • Other mechanisms such as a rack and pinion mechanism or a mechanism including friction wheels may be used in place of the drum and cable assembly to adjust the wall angle.
  • Figure 10 shows a cantilever frame which, in a preferred embodiment, is of lightweight metal construction such as aluminum or tubular steel. This construction keeps obstructions well clear of the climbing wall face so that a falling climber will not sustain injury as a result of striking any part of the structure during a fall.
  • the climber attaches the carabiner to his waist and begins to climb the simulated rock face. Initially, with the 3 lb. weight holding the brake on via a first rope, the simulated rock face is locked in place. When the climber reaches a predetermined height, a second rope, attached to the carabiner, lifts the weight, thereby releasing the brake, and the simulated rock face begins to descend under the climber's weight until the second rope becomes slack and the brake is reapplied.
  • the angle of the simulated climbing wall may be changed by removing locking pin (94), turning hand wheel (91) until channel (3) is at the desired angle and the hole in box (92) is aligned with one of the holes (93) in horizontal frame member (90) and reinserting locking pin (94) .
  • a surface board may be removed when the board is at the back side of the climbing frame. Removal of one pin is sufficient allow the second frame to be taken out of from the first frame. Thus the task can be performed by one person from one side of the climbing frame.
