Abstract

Abstract An electric radiant heating panel includes a gypsum panel incorporating a length of electrical resistance heating wire therein having ends adapted to be connected to source leads at the rear surface of the panel by connection members. Each connection member comprises a short length of wire attached at one end to the heating wire and carrying a sleeve-like member on the other end adapted to receive source leads from two directions whereby a plurality of such panels can be connected electrically in parallel with the source leads. A cover is provided over the connection members at the rear of the panel and comprises a section of gypsum panel scored through one cover sheet and the gypsum core so that the section is divided into two portions whereby the other cover sheet acts as a hinge. One portion is secured to the rear surface of the panel, while the other portion is recessed to receive the connection members and source leads and is pivotally movable about the hinge relative to the rear surface of the panel to selectively cover or expose the source leads and connection members.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 176 words
An electrical heating panel carrying a length of electrical resistance heating wire therein having ends adapted to be connected to source leads, a pair of connection members each having one end connected to a respective end of said heating wire and the other end adapted to be connected to source leads at a rear surface of said panel, a cover for the connection of said connection members to said source leads at a rear surface of said panel, comprising, a section of panel having a layer of gypsum between two flexible cover sheets, said section being scored through one sheet and said layer so that said other sheet acts as a hinge and said section is defined in two portions, one of said portions secured to the rear surface of the panel, a recess defined in the other portion, said one of said portions being positioned on said panel such that said other portion may be pivoted to contact the rear surface and receive the connections of the connectors to the source leads in said recess.
Claim 2
Dependent Claim 176 words
An electrical heating panel carrying a length of electrical resistance heating wire therein having ends adapted to be connected to source leads, a pair of connection members each having one end connected to a respective end of said heating wire and the other end adapted to be connected to source leads at a rear surface of said panel, a cover for the connection of said connection members to said source leads at a rear surface of said panel, comprising, a section of panel having a layer of gypsum between two flexible cover sheets, said section being scored through one sheet and said layer so that said other sheet acts as a hinge and said section is defined in two portions, one of said portions secured to the rear surface of the panel, a recess defined in the other portion, said one of said portions being positioned on said panel such that said other portion may be pivoted to contact the rear surface and receive the connections of the connectors to the source leads in said recess.
Claim 3
Dependent Claim 31 words
The apparatus of claim 1 wherein the connection members connect source leads between twO other adjacent panels and the heating wires of each panel are in parallel with the source leads.
Claim 4
Dependent Claim 41 words
The apparatus of claim 1 wherein said connection members each comprise a length of conductor having one end connected to the heating wire and carrying a sleeve-like member on the other end thereof adapted to receive source leads from two directions.
