Abstract
The invention relates to a screen tensioning system having a mesh screen and a U-shaped channel that engages an edge of the mesh screen. A clamp engages the U-shaped channel and the mesh screen. A frame having a substantially H-shaped cross section, wherein parallel side members converge to define a longitudinal slot permit the mesh screen to extend through the longitudinal slot, yet the clamp remains secured within the frame. A plurality of fasteners secure the clamp to the frame and are tightened to apply varying degrees of local tension to the screen. Preferably, no fasteners are used to secure the screen to the clamp.
Claims8
A screen tensioning system comprising:
- a mesh screen having a lip formed along an edge of the mesh screen, wherein the lip is bent approximately perpendicular to a field of the mesh screen;
- a U-shaped channel having an open end, wherein the lip of the mesh screen is secured within the U-shaped channel with adhesive;
- a longitudinal clamp having a top portion and a bottom portion, wherein the bottom portion is configured to receive the U-shaped channel and the top portion is configured to fit over the open end of the U-shaped channel and be secured to the bottom portion;
- a frame configured to receive the longitudinal clamp therein and the frame having a longitudinal slot along its length and approximately perpendicular to the open end of the U-shaped channel, wherein a width across the longitudinal slot is less than a width of the open end of the U-shaped channel;
- and
- a plurality of fasteners disposed on a side of the frame opposing the longitudinal slot of the frame, wherein the plurality of fasteners are configured to move the longitudinal clamp away from the longitudinal slot when rotated in order to apply tension to the field of the mesh screen.
A method of securing a security screen to a frame comprising the steps of:
- securing an edge of a security screen having a lip formed along an edge of the security screen, wherein the lip is bent approximately perpendicular to a field of the security screen;
- clamping the U-shaped channel in a clamp assembly that is substantially coextensive with the U-shaped channel, wherein the lip is secured within an open end of the U-shaped channel with adhesive, and the clamp assembly having a top portion and a bottom portion, wherein the bottom portion is configured to receive the U-shaped channel and the top portion is configured to fit over the open end of the U-shaped channel and is secured to the bottom portion;
- sliding the clamp assembly into a frame member having a size and dimension to entrap the clamp assembly;
- wherein the frame has a longitudinal slot along its length and is approximately perpendicular to the open end of the U-shaped channel, wherein a width across the longitudinal slot is less than a width of the open end of the U-shaped channel;
- securing the clamp assembly to the frame member with a plurality of fasteners;
- and applying tension to the screen, wherein the plurality of fasteners are disposed on an a side of the frame opposing the longitudinal slot of the frame and are rotated to move the clamp assembly away from the longitudinal slot to apply said tension.
