Abstract
A vision unit which can be easily assembled into the opening in a door such as a fire door which is constructed so that it can withstand high temperatures without disintegration. The vision unit is readily assembled into an opening in the door by one person working alone. The vision unit is composed basically of two frame members, two lower support elements and a biasing element which extends between the wall surface at the top of the opening and one of the support arms of the frame. The support arms include sharp edge portions for contacting a transparent panel member. Securing means such as threaded nuts and bolts or screws pass through the door opening and fasten the frame members to the door as well as to the panel member.
Claims25
A fire resistant vision unit for assembly in an opening in a door or the like comprising:
- a first frame member adapted to be mounted in said opening to one side of said door;
- a second frame member adapted to be mounted in said opening and to the opposite side of said door;
- said first and second frame members having flange sections for extending over peripheral edges of said opening;
- securing means clamping the first and second frame members to the door and to a transparent panel member
- support arms extending toward each other from said first and second frame members into said opening and defining an open holding channel;
- said transparent panel member disposed in said channel;
- wherein said support arms maintain said panel in place including times when said panel becomes semi-molten said support arms including inwardly biased sharp edge portions in contact with said panel member wherein said sharp edge portions will imbed in said panel member when said panel becomes semi-molten and;
- at least one support element positioned between said first and second frame members and closing the open channel to support the bottom of said panel member.
An easily assembled window unit in a kit form for assembly by one person into a fire door opening comprising:
- a first frame member adapted to be mounted in said door opening to one side of said door;
- a second frame member adapted to be mounted in said opening and to the opposite side of said door;
- said first and second frame members having flange sections for extending over peripheral edges of said opening;
- securing means for clamping the first and second frame members to the door and to a fire resistant, transparent panel member
- support arms adapted to be positioned so as to extend from said first and second frame members into said opening to define an open continuous holding channel;
- said fire resistant, transparent panel member constructed to be disposed in said channel;
- wherein said support arms maintain said panel in place including times when said panel becomes semi-molten said support arms including inwardly biased sharp edge portions for directly contacting said panel member upon assembly of the window unit wherein said sharp edge portions will imbed in said panel member when said panel becomes semi-molten;
- and
- at least one support element for positioning between said first and second frame members and closing the open channel to support the bottom of said panel member.
