  • Patent number: 6419610
    Abstract: A truncated triangular inclined climbing wall is attached to a wooden play structure, and is tilted at about a forty-eight degree angle against the play structure, and is fastened by a flange to an elevated deck which is accessible through a wood framed inlet. The climbing wall is staked to the ground, and narrows from a wide, ground-engaging, base, to a narrower summit, which is immediately adjacent the framed inlet. The climbing wall is formed with a number of rock-simulative ledges, which progress from the base to the summit. Each molded ledge preferably has a child-graspable hand grip integrally molded in the riser. The top surfaces of the step-like ledges define treads which are inclined from the horizontal to direct the child's foot inward toward the climbing wall rather than away from the wall and off the structure.

  • Patent number: 6193633
    Abstract: Three thermoformed polyethylene plastic segments are bolted together to form a truncated triangular inclined climbing wall for attachment to a wooden play structure. The climbing wall is tilted at about a forty-eight degree angle against the play structure, and is fastened by a flange to an elevated deck which is accessible through a wood framed inlet. The climbing wall is staked to the ground, and narrows from a wide, ground-engaging, base, to a narrower summit, which is immediately adjacent the framed inlet. The climbing wall is formed with a number of rock-simulative ledges, which progress from the base to the summit. Each molded ledge preferably has a child-graspable hand grip integrally molded in the riser. The top surfaces of the step-like ledges define treads which are inclined from the horizontal to direct the child's foot inward toward the climbing wall rather than away from the wall and off the structure.
