Abstract

An edge guard for the trailing edge of a swinging closure comprises a metal strip formed into a general U-shape so as to have inner and outer legs of single thickness extending from a semi-circular base. Non-metallic insulating material is applied to the metal strip so as to be disposed in covering relation to at least certain portions of the strip including a covering relation which prevents the metal of the channel from contacting the trailing edge. Some non-metallic material is applied to the metal strip at locations where the legs apply self-retention force to the trailing edge and has a higher durometer than at other locations where non-metallic material is applied to the metal channel. In the preferred embodiment the higher durometer material also covers the distal end edge surfaces of the legs.

Claims

1. In combination with the trailing edge of a swinging closure, a self-retaining insulating metal edge guard fitted onto said trailing edge comprises an elongate metal channel having in transverse view inner and outer legs extending from a generally semi-circular base, said inner and outer legs serving to apply self-retention forces to opposite sides of said trailing edge, said channel being formed from a metal strip of uniform thickness having side edge surfaces which become distal end edge surfaces of the legs in the channel, non-metallic insulating material disposed on the metal channel in covering relation to said legs and base including a covering relation wherein direct contact of the metal of the channel with said trailing edge is prevented by said non-metallic insulating material, said non-metallic insulating material having respective zones, one of said zones being on one leg at the location of force application by that leg to said trailing edge, another of said zones being on the other leg at the location of that other leg'"'"'s force application to the trailing edge, and a further of said zones disposed on the channel between said one and said another zones wherein said one and said another zones are of harder non-metallic insulating material than said further zone of non-metallic insulating material.

2. The combination set forth in claim 1 in which said one and said another zones of non-metallic insulating material are disposed on the metal channel so that the force applied to the trailing edge by each leg is transmitted through the corresponding one of said one and said another zones.

3. The combination set forth in claim 1 in which said one and said another zones of non-metallic insulating material also extend in covering relation to the distal end edge surfaces of the respective legs.

4. The combination set forth in claim 1 in which said one and said another zones are disposed in covering relation to the distal end edge surfaces of the respective legs and immediately contiguous marginal portions of the interior and the exterior of each respective leg.

5. The combination set forth in claim 1 in which said one and said another zones each partially overlaps a corresponding portion of said further zone.

6. The combination set forth in claim 5 in which said one and said another zones partially overlap said further zone at the distal end edge surfaces of the respective legs and an immediately adjacent marginal portion of the respective legs.

7. The combination set forth in claim 1 in which said non-metallic insulating material is so disposed as to cover the full exterior of the metal channel.

8. The combination set forth in claim 7 in which said insulating material which covers the full exterior of the metal channel is constituted by the extension of said one and said another zones in covering relation to the exterior of the metal channel.

9. The combination set forth in claim 1 in which said legs are generally parallel with each other.

10. In combination with the trailing edge of a swinging closure, a self-retaining insulated metal edge guard comprising an elongate metal channel having in transverse view inner and outer legs extending from a generally semi-circular base, said inner and outer legs serving to apply self-retention forces to opposite sides of said trailing edge, said channel being formed from a metal strip of uniform thickness having side edge surfaces which become distal end edge surfaces of the legs in the channel, non-metallic insulating material disposed on the metal channel in covering relation to said legs and base including a covering relation wherein direct contact of the metal of the channel with the trailing edge is prevented by said non-metallic insulating material, said non-metallic insulating material having respective zones, one of said zones being in covering relation to the distal end edge surface of one of said legs and an immediately contiguous side of the same leg, another of said zones being in covering relationship to the distal end edge surface of the other leg and an immediately contiguous side of the same leg, said non-metallic insulating material having a further zone disposed on the metal channel between said one and said another zones, and wherein said one and said another zones are of non-metallic insulating material which is of higher durometer than that of said further zone of insulating material.

11. The combination set forth in claim 10 in which the material of said one and said another zones extends from the corresponding distal end edge surface onto immediately contiguous margins of each leg on both the interior and the exterior of the channel.

12. The combination set forth in claim 11 in which said one and said another zones are extended on the interior of the channel so as to cover the full exterior of the channel.

13. The combination set forth in claim 10 in which said one and said another zones of non-metallic insulating material partially overlaps respective portions of said further zone of non-metallic insulating material.

14. The combination set forth in claim 13 in which said overlapping occurs on the interior of the metal channel.
