Abstract: A device for stretching a canvas mounted to a frame comprises a spacer and a screw. The frame has a plurality of side members each mutually abutting at angled ends. A first portion of the spacer includes a central aperture therethrough and two opposing ends or sides. Each end of the first portion is sized to engage a contact surface of each side member. The screw has a threaded shaft adapted for rotational engagement with the central aperture of the first portion of the spacer. The threaded shaft terminates at a first end thereof with a screw head that has a frustoconical side wall and an end surface that includes a tool-engaging recess. Rotating the screw to move the screw head closer to the spacer causes the spacer to push the side members mutually away from each other to stretch the canvas.

Abstract: The gym locker attached privacy cover creates a privacy area behind an arched privacy screen where a user may change clothing without being seen. The gym locker attached privacy cover attaches to gym lockers at a first support column and a second support column. An opaque screen stored without the support columns is deployed from around spindles within each support column and wires in the opaque screen cause the opaque screen to form an arch that projects away from the lockers. The user may stand within the space defined between the lockers and the arch. The first support column and the second support column may each be held in place by a set of magnets. In some embodiments, the privacy screen may be retracted by a spring-loaded ratchet and pawl arrangement or by a manually operated knob attached to the spindle.

Abstract: The present invention presents a stretching frame for fabric materials such as an artist's canvas which can be easily assembled and disassembled, while providing superior rigidity. Unique inner frame members interlock orthogonally along the inner length of outer frame member to prevent the tension of the canvas from deflecting the frame inwardly. Half lapped joints at the corners of the inner frame members provide additional strength for the frame and the ability to adjust the tautness of the canvas in either a single direction or two directions by the insertion of wedges or turnbuckles.

Abstract: A stretcher bar framing device having a narrow top surface, an interior surface, an exterior surface and an angled edge such that a stretched canvas touches only the top surface. The top surface provides a surface for supporting a painting canvas, reducing the surface area contacting the canvas and increasing the paintable surface. A bottom surface of the frame contains a channel so that the canvas material is folded over the top along an exterior surface and folded into a channel so that a rubber spline may be inserted attaching the canvas to the frame without the need for staples.
