Shock absorbing, wheelchair accessible, recreational surface area and method of constructing same

Abstract

A recreational play area meeting a fall height requirement and being constructed essentially of one or more layers of shock absorbing synthetic material such as dimpled polystyrene, running to a perimeter structure consisting of nailer boards and collector drain. The shock absorbing layer is overlaid with polyethylene synthetic turf filled with a sand/rubber mixture for added shock attenuation.

Description

FIELD OF THE INVENTION[0001]This invention relates to recreational play areas and more particularly to a recreational play area with shock-absorbing qualities for fall-caused injury protection constructed by laying one or more layers of shock-absorbing material over a base such as asphalt, concrete or dirt. The shock absorbing layer or layers are then overlaid with synthetic turf to provide a natural appearance, as well as high durability and low maintenance requirement. The surface is also wheelchair accessible in that it provides a surface which is uniform and low-friction.BACKGROUND OF THE INVENTION[0002]Recreational areas, such as playgrounds and / or playscapes, have traditionally been characterized by dirt or turf surfaces which provide only minimal protection against injury due to falls. More recently, it has become popular to spread shredded rubber on the recreational surface area, around and under swings, slides, climbing bars and other recreational equipment. The principal p...

Benefits of technology

[0005]In accordance with one aspect of my invention, a shock absorbing, fall safe, uniform recreational play surface area is provided by laying one or more pre-fabricated layers of sheet-like shock-absorbing material over a base; i.e., the desired fall height safety function is met by selecting the number of layers of material rather than by pouring. This greatly simplifies the installation procedure and eliminates the need for mixing and pouring materials. The shock attenuating material layers are usually sold in rolls which are relatively easily transported and which may be joined to one another by taping seams. The area is defined by a base which may be natural or constructed of concrete or asphalt. Because of the uniformity of the surface, it is easily wheelchair accessible and low in maintenance.

[0006]In accordance with a preferred embodiment of the invention, a collector drain is created around at least part of the periphery of the play area. At least one ply or layer of thin impervious polymeric material is then placed over the base so as to extend to the collector drain, the area preferably being sloped or grated toward the collector drain. The impervious layer is then overlaid with at least one layer of shock attenuating material which is then topped with a synthetic turf of wear-resistant polyethylene or the like. The turf may be filled with a mixture of sand and rubber to provide additional shock protection.

Problems solved by technology

Because of the uniformity of the surface, it is easily wheelchair accessible and low in maintenance.
