Adjustable biaxial stretcher

Claim 1

An adjustable stretcher device for positioning and holding frame structures of various dimensions and for biaxially tensioning a screen fabric across the frame structures, said adjustable stretcher comprising: (a) a generally flat base member for supporting the remaining elements of the device, (b) a pair of elongated opposing and perpendicularly disposed track members for securement to said base member, said track members having securement means to fasten said track members to said base member in a generally radial position from the center of said base member, each said track member further having an internally disposed sliding groove along its length, (c) a clamping member for slidingly engaging each said track member, each said clamping members having a sliding plate body for slidably engaging said internally disposed groove members of said track members and having an adjustable set screw means, a handle member, an elongated connector shaft in communication with said handle member and a shaft support cylinder mounted to said sliding plate body, each said connector shaft further having a widened end portion, and (d) an elongated stretcher module body having a body member, and further having a longitudinally extending channel member for slidingly receiving the widened end portion of said connector shaft, whereby the movement of the clamping members on said track members, the movement of said stretcher module body on said widened end portion of said connector shaft and the movement of the handle member of said clamping member permits a user to adjust the tension of screen fabric material biaxially across a frame structure placed within the adjustable perimeter of said elongated stretcher module bodies.
