Provided is a prefabricated shelf assembly. The prefabricated shelf assembly enables a shelf to be conveniently and rapidly assembled, enables the assembled shelf to be firmly maintained, and allows an outer wall and a door to be assembled as a user desires, thus realizing a high-quality product, and allows the length of the shelf to be adjusted via an assembly kit or allows a plurality of shelves to be optionally arranged and then be assembled depending on an installation environment, and adopts a coupling method using a fitting protrusion and a fitting hole, so that the shelf may be re-assembled by separating only a support plate even when the assembly has been completed, and thereby the height of a storage part can be easily changed.

A shelving unit includes a plurality of posts, a plurality of shelf-supporting beams attached to the plurality of posts to form a shelf support frame, and a shelf. The shelf has a plurality of sides seated on the shelf support frame. The plurality of the sides of the shelf includes a depending flange. At least one of the depending flanges extends downwardly along a respective shelf-supporting beam between about 30% and about 100% of the height of the shelf-supporting beam. Another shelf unit is further disclosed where the shelves include a color that corresponds to a color-coded system for organizing the storage of items on the shelving unit. A method of organizing a shelving unit utilizing the color-coded shelf system is also disclosed.

A device for connecting modular metal shelving units, comprising at least two props (1) and at least one connecting element (2), for mutual coupling of the two props (1). Each prop (1) comprises central couplings (14), first distal couplings (16) and second distal couplings (17), and each of the couplings (14,16,17) comprises a central coupling (11) and a first adjustment slot (12). The connecting element (2) comprises a first grouping (21) of pins (20), which can be inserted into the first distal couplings (16) of a prop (1), and a second grouping (22) of pins (20), which can be inserted into the second distal couplings (17) of another prop (1). The first adjustment slot (12) of the first distal couplings (16) is diametrically opposed to the first adjustment slots (12) of the central couplings (14) and the second distal couplings (17).

An example apparatus includes a bracket having a rack attachment member and a guard attachment member, and upper and lower engagement tabs that are coupled to the rack attachment member and have a stem portion and a head portion. The rack attachment member has a lock pin hole above the lower rack engagement tab. The lock pin hole is sized and positioned to provide sufficient cross-sectional area within a rack engagement distance to allow passage of a bracket lock pin therethrough within the rack engagement distance. The apparatus further includes a bracket lock pin having a stabilizing leg coupled to a lock pin head, where the stabilizing leg fits through the lock pin hole and the lock pin head does not. The stabilizing leg urges the lock pin head toward the lock pin hole when the stabilizing leg is passed through the lock pin hole.

The present invention discloses a connecting structure, a connecting method and an article containing the connecting structure. The connecting structure includes a fastener, a first connecting member adjacent to the trailing end of the fastener and a second connecting member away from the trailing end of the fastener. The second connecting member is provided with a threaded connecting hole, which in the axial direction thereof is provided with thread matching with the form of thread of the fastener and having a central angle of at least 180 degrees. The first connecting member is provided with a connecting hole, and the fastener connects the two connecting members through the threaded connecting hole and the connecting hole. The connecting method achieves quick connecting with the connecting hole of the first connecting member by preloading the fastener to the threaded connecting hole, without being affected by the assembly space. The connecting structure and the connecting method can be used in a variety of articles. The thickness of the threaded connecting hole is equal to the pitch of the fastener. The form of thread of the threaded connecting hole is fitted with the thread of the fastener by only one turn, which during processing can be made directly in the form of stamping, resulting in a simple processing and improving the processing efficiency.
