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.
Claims20
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
- an attachment feature on the plurality of mounting patches, the attachment feature configured to attach the mechanical load to the substrate,
- wherein the substrate comprises:
- a first substrate panel having a first seaming edge;
- and
- a second substrate panel having a second seaming edge, wherein the second seaming edge is joined to the first seaming edge to form a seam.
A projection screen comprising:
- a substrate having at least one mounting edge;
- and
- 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,
- wherein the substrate comprises:
- a first substrate panel having a first seaming edge;
- and
- a second substrate panel having a second seaming edge, wherein the second seaming edge is joined to the first seaming edge to forma seam,
- wherein a first mounting patch has a shape selected from the group consisting of a square shape, a rectangular shape, a quadrilateral shape, an oval shape, a circular shape, a triangular shape, and an asymmetric shape.
A projection screen comprising:
- a substrate having at least one mounting edge;
- a plurality of mourning, 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,
- wherein the substrate comprises:
- a first substrate panel having a first seaming edge;
- and
- a second substrate panel having a second seaming edge, wherein the second seaming edge is joined to the first seaming edge to form a seam.
