Some embodiments relate to a picture frame including a first pair of frame profiles, second pair of frame profiles, connectable to compliment to a right-angled corner at an assembled position. The second frame profiles have a locking groove extending from a bottom face thereof. The first and second frame profiles each have a stepped section at an inside face thereof, with a picture facing lip disposed above a bottom face. There is a corner coupler having a first arm slidingly displaceable for slidably arresting within an open end of the back board arresting groove of a first frame profile, and a second arm configurable for arresting into locking groove of the second frame profile. A back board having first opposite edges having length corresponding with the first length of the first frame profiles, and second opposite edges having length corresponding with second length of second frame profiles can be included.

The invention refers to a support device for board panels having a connecting rod with a first end and a second end, a front bulkhead, an intermediate bulkhead, a rear bulkhead and an element connecting to a surface including an orifice, which are interconnected to each other. The invention also refers to a board panel support and junction system having the support device and the associated preparation method. The present invention has the advantage of connecting adjacent board panels such that the intervals formed between them are not apparent, wherein the board panels are, for example, board panels configured for writing or for fastening papers.

A picture frame includes four frame sides forming a rectangular frame structure. An end portion of each frame side is provided with a mounting groove, and the frame side is provided with a picture groove for receiving an edge of a picture. The picture frame also includes four corners, with each corner arranged between two adjacent frame sides and provided with an insertion portion. The insertion portion is configured to be inserted into the mounting groove and connected to the mounting groove in a detachable manner. Each of the frame sides includes a first side that faces away from a wall surface during use and a second side that faces the wall surface during use. The picture groove is provided on the first side and/or the second side of each of the frame sides.

The present disclosure relates to a corner connector for frames and modular structures, designed for seamless and reversible frame assembly. The corner connector comprises an expandable body and a central channel to house a screw. Upon screw tightening, the connector expands against the frame bars to ensure a secure corner joint. The corner connector is made from materials such as plastics, metals, and composites, for durability and flexibility for repeated use. Internally threaded, the central channel pairs with a complementary threaded screw, facilitating a strong interlock with frame bars that feature mating semi-circular notches. The body's textured exterior enhances grip, ensuring a stable, aesthetic finish.

A repositionable frame system includes a frame component for holding an image substrate and having a rear face. The system further include a frame mount that is fixedly attached to the rear face of the frame component. The frame mount comprises a first magnetic element. The system also includes a repositionable wall pad for placement on a support surface and configured to detachably couple to the frame mount. The wall pad includes a cross-linked closed cell polyethylene foam having a first face that faces away from the frame mount and an opposite second face that faces the frame mount. The wall pad further includes a removable transfer adhesive layer disposed directly along the first face, a permanent transfer adhesive layer disposed directly along the second face, and a second magnetic element that is magnetically attracted to the first magnetic element.
