  • Patent number: 6665987
    Abstract: In the first embodiment, a staircase repair device or kit is provided which includes two components, namely, a stair tread repair member and a riser repair member. These members are placed on an existing staircase to provide a protective covering. In the second embodiment, a new staircase construction is provided which includes a plurality of stair tread members spanning between standard stringers. The components of the first embodiment and the stair tread member of the second embodiment are made of metal bent to desired shapes. Each is coated with a synthetic material to coat exposed surfaces or to completely encapsulate them therein. A slip-free wearing surface is formed by a layer of particles placed over the first coating, and a second coating of synthetic material which is applied over the dispersed layer of particles.

  • Patent number: 6438909
    Abstract: A heating assembly is provided which includes a metal stair tread member having an upper horizontal surface and a bottom surface for mounting on a stair tread of a staircase. A strip heating element is attached to the bottom surface of the stair tread member. A first covering of synthetic material encapsulates the horizontal surface of the metal stair tread member and the strip heating element on bottom surface of the stair tread member. The strip heating element is contiguous with the bottom surface and is attached thereto by a gasket extending around the peripheral edge of the strip heating element. A thermostat is electrically connected to the strip heater and to a power source for selectively supplying electric current to the strip heater in response to changes ambient temperatures. A temperature sensing element is in electrical communication with the thermostat wherein the thermostat selectively supplies the current to the strip heating element.
