Abstract
A method of mounting screen material may include a screen mounted to a frame at multiple mounting points. One embodiment may include mounting patches attached along the perimeter of the screen. These mounting patches may be strain relieved in order to enable rolling the screen without sacrificing the in-plane rigidity of the patches when the screen is mounted to a frame. Stated differently, the strain relieved patches may reduce the strain on the screen in the circumstance the screen is rolled onto a core. The mounting patches may be strain relieved by locating notches or slits in the mounting patch.
Claims32
A projection screen comprising:
- a substrate having at least one mounting edge;
- a plurality of mounting patches attached to the substrate along the at least one mounting edge, the plurality of mounting patches configured to uniformly distribute a mechanical load across the substrate;
- and
- a first strain relief feature in a first mounting patch, the first strain relief feature configured to reduce the bending stiffness of the first mounting patch.
A mounting patch for a projection screen, comprising:
- a substrate;
- an attachment feature in the substrate, the attachment feature configured to attach a mechanical load to the projection screen when the mounting patch is attached to the projection screen;
- and
- a strain relief feature in the substrate, the strain relief feature configured to reduce the bending stiffness of the mounting patch when the mounting patch is attached to the projection screen and further configured to maintain in-plane rigidity of the mounting patch when the mounting patch is attached to the projection screen.
A method for assembling a projection screen system, the method comprising:
- locating a projection screen comprising a substrate having at least one mounting edge, the projection screen further comprising a plurality of mounting patches attached to the substrate along the at least one mounting edge, the plurality of mounting patches configured to uniformly distribute a mechanical load across the substrate, the projection screen further comprising a first strain relief feature in a first mounting patch, the first strain relief feature configured to reduce the bending stiffness of the first mounting patch while maintaining in-plane rigidity of the first mounting patch;
- and
- attaching the plurality of mounting patches to a frame.
