Patent application numberDescriptionPublished
20080256895CORNER JOINT FOR SILK SCREEN FRAMES - A corner joint for constructing silkscreen frames, comprising a first insert member, a second insert member connected perpendicularly to the first insert member, and a means for achieving an air-tight fit between the insert members and frame side members. The free ends of the first and second insert members have at least one tapered surface. The insert members are adapted to be received inside an end of a frame side member and tightly engage the frame side member.10-23-2008

20110284023ORTHODONTIC FLOSSER - An orthodontic flosser comprising an elongated handle and a head coupled to the handle at a vertical angle is disclosed. A first and second projection extend from the head for suspending floss, the first projection is sized for insertion of floss between a wire affixed to a tooth and the tooth. A source spool of fresh floss is configured to feed fresh floss incrementally into suspension between the first and second projections while a take-up bobbin is configured for taking up used floss and applying tension to the suspended floss. A button may be used for releasing the source spool to rotate, and for holding the source spool against rotation. The source spool and take-up bobbin may be disposed in separated chambers to reduce cross contamination.11-24-2011

20100263558SCREEN-PRINTING PANEL - A screen-printing panel comprising a locking strip sewn to screen-printing mesh is described. The mesh along an edge of the panel is folded around the locking strip and secured using a line of stitching. A gap between the end of the locking strip and the edge of the mesh contributes to corner softening. Another gap between the end of the stitching and the end of the locking strip also contributes to corner softening. Locking strips have various cross sections including rectangular, triangular, and complex curves. Two colors of thread may be used to aid in orienting the panel. An adhesive may be used to hold the mesh to the locking strip for convenience during handling and sewing.10-21-2010
20100269717PIVOTING LOCKING STRIP SYSTEM AND APPARATUS FOR SILKSCREEN FRAME - A frame for tensioning fabric such as a silkscreen mesh is described. The frame includes a groove for securing the fabric using a locking strip. The groove includes a central cavity between a groove floor and a groove entrance, an insertion cavity coupled to the groove entrance and the floor, a side cavity opposite the central cavity from the insertion cavity and coupled to the groove entrance and the floor, and a pivot disposed on the groove floor. The side cavity includes a vertex. The insertion cavity may be adjacent the central cavity. A portion of the side cavity may be removed at an end of the frame for softening corners of the fabric or mesh. Locking strips may be stitched to edges of the fabric or mesh.10-28-2010
20100276091APPARATUS AND METHOD FOR SCREEN TENSIONING - A screen fabric frame is disclosed including a locking strip and a frame member. The frame member includes a locking strip groove extending at least a portion of a length of the frame member. The locking strip groove includes a central groove configured to receive the locking strip, a minor side groove having a minor depth, and a major side groove distal the central groove, the major side groove having a major depth greater than minor depth of the minor side groove.11-04-2010
20100300312SCREEN-PRINTING FRAME - A system for attaching mesh to a frame and applying tension to the mesh is described. The system includes a locking strip slot in a movable frame member that permits mesh and an attached locking strip to be inserted into the slot from the top. The locking strip may be asymmetric. The system further includes a rigid frame that can hold the movable frame member under tension. The system also includes gripping the movable frame member at the locking strip slot to apply tension to the mesh. A simple hand tool may be used for engaging the locking strip slot and leveraging against the rigid portion of the frame to apply the tension. A simple hand tool may be used for separating the movable frame member from the rigid frame to remove the mesh.12-02-2010
20110155003ROLLER FRAME STRETCHER - Mesh may be stretched between rollers of a roller frame using a tool to grip a locking strip slot in the roller at about the middle of the roller and turning the roller using the tool. A rectangular frame may support the roller frame in a planer configuration during stretching. A jack coupled to the rectangular frame may be used to apply rotational force to the tool for rotating the roller. A triangular locking strip may be stitched to the mesh for insertion into the locking strip slot from the top instead of the end of the slot.06-30-2011
