Abstract
Abstract An insert panel support structure especially adapted for use in a hollow metal door to frame an opening for an insert panel, such as a glass panel. The channels defining the support structure are longer than the length of the respective sides of the opening and need not be cut to length to preform a support structure of a predetermined size. The channels are so arranged that the end of one channel abuts an overlapping mating channel to frame the opening.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
238 words
In a door having first and second spaced skins and at least one multisided opening through each skin, said openings overlying one another to define a through passage, the combination comprising a plurality of channel members secured between said skins, one channel member being provided for each side of one of said openings, each channel member having a first end located at one corner of said one opening and a second end extending at least beyond an opposite corner of said one opening along a side of said opening, said first end of each channel member being in abutment with a side of one other channel member, the second end of each channel member extending between said spaced skins beyond the abutting first end of another channel member for framing said one opening by means of channel members having lengths longer than the length of the sides of said one opening, a plurality of molding members, the number of molding members being equal to the number of channel members, and fastening means releasably securing each molding member in overlying relationship with a cooperating one of said channel members, each of said molding members having at least one leg and each of said channel members having at least one leg, said one leg of each channel member being spaced from said one leg of its overlying molding member to define a slot for receiving and supporting an insert panel.
Claim 2
Dependent Claim
238 words
In a door having first and second spaced skins and at least one multisided opening through each skin, said openings overlying one another to define a through passage, the combination comprising a plurality of channel members secured between said skins, one channel member being provided for each side of one of said openings, each channel member having a first end located at one corner of said one opening and a second end extending at least beyond an opposite corner of said one opening along a side of said opening, said first end of each channel member being in abutment with a side of one other channel member, the second end of each channel member extending between said spaced skins beyond the abutting first end of another channel member for framing said one opening by means of channel members having lengths longer than the length of the sides of said one opening, a plurality of molding members, the number of molding members being equal to the number of channel members, and fastening means releasably securing each molding member in overlying relationship with a cooperating one of said channel members, each of said molding members having at least one leg and each of said channel members having at least one leg, said one leg of each channel member being spaced from said one leg of its overlying molding member to define a slot for receiving and supporting an insert panel.
Claim 3
Dependent Claim
107 words
The combination claimed in claim 1 wherein each of said molding members has a first end located at one corner of the other of said openings and a second end extending at least beyond an opposite corner of said other opening along a side thereof, said first end of each molding member being in abutment with a side of one other molding member, the second end of each molding member extending between said spaced skins beyond the abutting first end of another molding member for framing said other opening by means of molding members having lengths longer than the length of the sides of said other opening.
Claim 4
Dependent Claim
43 words
The combination claimed in claim 1 wherein said one opening is of smaller dimension than the other opening, said channel members each including a center portion extending perpendicularly to the plane of said one opening and being substantially flush with the side thereof.
Claim 5
Dependent Claim
32 words
The combination claimed in claim 3 wherein each of said channel members includes a base portion extending to the plane of the other opening and being substantially flush with the side thereof.
Claim 6
Dependent Claim
43 words
The combination claimed in claim 4 wherein each of said molding members includes a base portion extending perpendicularly to the plane of said other opening and being substantially coplanar with the center portion of the channel member to which it is releasably secured.
Claim 7
Dependent Claim
53 words
The combination claimed in claim 1 wherein each channel member has two spaced outer legs with each leg secured to a respective one of said skins adjacent said openings, each leg of a channel member having extending therefrom a base portion substantially flush with the side of the opening from which it extends.
Claim 8
Dependent Claim
41 words
The combination claimed in claim 6 wherein one of said outer legs includes an offset adjacent its respective base portion for receiving between said offset and the skin to which said leg is affixed a portion of said overlying molding member.
Claim 9
Dependent Claim
56 words
The combination claimed in claim 7 wherein said molding members are formed as U-shaped members having legs and a base portion, the portion of said molding member received in said offset portion being one of said legs, the outer edge of the other of said legs being in abutment with a surface of said channel member.
