The present disclosure provides various examples of a universal mounting bracket for mounting a floating shelf to a flat vertical surface such as a wall. The bracket assembly allows for installing the bracket with a single selected fastener. This is more efficient and allows for the bracket to be installed in the widest variety of vertical assemblies with the most strength possible. The bracket can be installed into a stud wall, hollow drywall space, solid masonry wall, a hollow masonry wall unit, a brick wall, a cinderblock wall, a reinforced masonry wall, a plaster wall, a steel wall assembly or support structure, and any other vertical assembly so long as there is a satisfactory fastener for that assembly. Alternatively, the universal mounting bracket provides a mechanism that facilitates its use as a hook for a multitude of purposes.

Described herein is a sanitization assembly including: a sanitization device, such as for example a photocatalytic device or ionizer or the like; and a containment element. The sanitization device is received in the containment element, and the containment element includes a box-shaped, box-like containment body. The box-like containment body includes side containment body surfaces and has dimensions in the width and thickness thereof that are substantially the same as those of a panel or rack or shelf of a furnishing element that includes side shelf surfaces. The box-like containment body can be assembled on the panel or rack or shelf, thus being continuous with the panel or rack or shelf. The side shelf surfaces substantially continue in the side containment body surfaces.

A shelf support beam (80, 130, 200) for use in a shelving unit (10) to support a shelf (22). A structural member (82, 132, 202) has a C-shaped cross-section. A web (94, 144, 216) separates a top flange (96, 146, 220) from a bottom flange (112, 162, 234). The top flange (96, 146, 220) is configured to support the shelf (22). The web (94, 144, 216), the top flange (96, 146, 220), and the bottom flange (112, 162, 234) define a channel (92, 142, 214) of the member (82, 132, 202). The channel (92, 142, 214) defines a cavity height (C1, D1, E1). The top flange (96, 146, 220) and the bottom flange (112, 162, 234) define a top flange width (C2, D2, E2) and a bottom flange width (C3, D3, E3), respectively. A ratio of the cavity height (C1, D1, E1) to a sum of the top flange width (C2, D2, E2) and the bottom flange width (C3, D3, E3) is greater than 1, is at least 1.20, or is about 1.40. The C-shaped cross-section has a moment of inertia (98, 148, 238) of greater than 0.40, greater than 0.45, or at least 0.46. The top flange (96, 146, 220) includes an elevated portion (100, 150, 222) and a lower or shelf support portion (104, 154, 226) separated by a sidewall (106, 156, 230).

The invention provides a side frame, which comprises a frame body formed by connecting vertical columns and a horizontal bar; and a plurality of supporting arms provided on the frame body; the vertical columns are provided with a plurality of mounting holes, two ends of each of the supporting arms are respectively connected with mounting holes of two of the vertical columns of the frame body; one end of the horizontal bar of the frame body is provided with a fixing device for installing the frame body to a wall body. The present invention also provides a storage rack with side frames. The storage rack comprises at least two side frames and a plurality of boards, each of which is positioned between two side frames, and can be detachably connected to the supporting arms on the side frames. The side frames of the present invention have simple structure and strong practicability. The supporting arms of the side frames can form a stable connection with the frame body of the side frames, thereby improving the structural strength of the side frames. The invention of the storage rack with the side racks has better supporting capacity and load bearing effect, thereby improving the practicability and stability of the storage rack.
