Filed:

Sep 15, 2000

Appl. No.:

09/663641

Inventors:

Kenneth J. Jonas - Janesville WI
Randall C. Grutza - Janesville WI
Matthew T. Bolland - Stoughton WI

Assignee:

PlayCore Wisconsin, Inc. - Chattanooga TN

International Classification:

A63B 1700

US Classification:

482 35, 482 37, 446110

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 childs foot inward toward the climbing wall rather than away from the wall and off the structure. To contribute to the rock-simulative visual effect of the thermoformed plastic assembly, polyethylene is extruded with a pattern of streaks or striations which, when molded, simulate the color variations of naturally occurring rock formations. The hypotenuse of the triangle provides both a climbing surface and a means for directing climbing children to the inlet.

US Classification:

482 35

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. To contribute to the rock-simulative visual effect of the thermoformed plastic assembly, polyethylene is extruded with a pattern of streaks or striations which, when molded, simulate the color variations of naturally occurring rock formations.
