Abstract: Novel tools and techniques are provided for concealing indoor wiring and cables while serving as architectural wall panels or adornments. In various embodiments, a system of architectural wall panels might include one or more architectural wall panels and a plurality of wall mounts that are removably securable to a wall. Each architectural wall panel might include a front face having a decorative or architectural pattern thereon, a rear face, and two or more mounting protrusions formed on a surface of the rear face. Each mounting protrusion and an adjacent mounting protrusion might form or define a vertical channel having a size through which cables can be disposed when the wall panel is mounted on the wall. The two or more mounting protrusions removably couple with two or more corresponding wall mounts that have been secured to the wall, thereby allowing the wall panel to mount on the wall.

Abstract: An explosion-proof arrangement (20) having a bushing part (23) with a bushing opening (24) that defines a bushing surface (25) and a structural unit (29) arranged in the bushing opening (24). The structural unit (29) includes a deformable inner body (31) with at least one conductor channel (32) extending through in a longitudinal direction (L), and a plastically deformable connecting sleeve (30) surrounding the inner body (31). At least one conductor (21) is guided through its own associated conductor channel (32) in the inner body (31). A connecting portion (33) of the connecting sleeve (30) is plastically deformed so that it presses radially inwardly on the inner body (31) and deforms it in a radial direction (R). A first delimiting surface (35) is formed on an outer circumference of the plastically deformed connecting portion (33). The bushing surface (25) forms a second delimiting surface (36).

Abstract: A recessed wall mounting apparatus and method are presented. The invention includes a housing unit coupled with a mounting ring.
