Abstract
An integrally moulded device for applying pressure to screen material or a retaining bead, to force same into a groove of a frame member is disclosed. The tool has a central body graspable by the human hand and a thin blade member at each end, each blade member having a straight edge surface extending from the body and a convexly arcuate edge surface extending from the outer end of the straight edge surface back to the body. One arcuate edge surface is transversely rounded for preforming screen material into the groove. The other arcuate edge surface is transversely V-shaped for pushing a flexible bead into the groove to retain the screen material therein. The shape of the blade members permits the application of pressure completely into corners defined by abutting grooves.
Claims5
A device for pushing a flexible material into a retaining groove for capture therein comprising:
- a central body member graspable by a human hand;
- a first thin blade member at one end of said body member and a second thin blade member at the other end of said body member;
- each of said blade members including a straight edge surface extending outwardly from adjacent one longitudinal edge of said body member and a convexly arcuate edge surface extending from adjacent the other longitudinal edge of said body member to the outer end of said straight edge surface and defining a sharp corner therewith, the arcuate edge surface of the first blade member being transversely rounded and the arcuate edge surface of said second blade member being transversely V-shaped.
The device of clim 1 wherein the straight edge surface of each of said blade members is coextensive with a different longitudinal edge of said body member.
