  • Double wall slide with varying sloped slide bed playground slide
    Patent number: 6342015
    Abstract: A double wall scoop shaped residential slide with an integrally formed footing attached to the underside of the slide bed and varying slope slide bed. The slide is formed from a one piece rotational molded process. The slide surface and walls form a U-shaped scoop defining a semi-circular slide bed, allowing for increased safety and structural support. The scooped shape provides integrally formed side walls which prevent the user from falling off the slide during use. The built-in footing is advantageous because it lowers manufacturing costs while increases stability and safety of the slide.
