The invention discloses a column-beam connecting assembly capable of being manually assembled, including connecting columns and connecting beams. The connecting column is formed with an arc channel along the axial direction. The arc channel opens to the surface of the column as a groove. A number of pairs of anchor slots are shaped on both sides of the groove, and the anchor slots of the same pair are at the same height. Mounting parts for snapping into the anchor slots are shaped on both sides of the connecting beam. Half T-shaped jointing heads are provided on the outer ends of said mounting pans for connecting to the arc channel, and said jointing heads are either in the shape of a column head matching the arc channel, or in the shape of a hook head. A frame structure assembled by the connecting parts is further disclosed.

A tool storage system has a universal mounting bracket coupled to a support surface formed with a plurality of apertures that align with differently sized support arms that support a tool therefrom. The apertures are aligned along a common horizontal plane and the support arms have different heights that allow tools to be hung therefrom in a nesting relationship so that more tools can occupy less space or area relative to the support surface. The nesting relationship of the tools provides for a first tool supported by the first arm to fit within a space defined by the second tool supported by the second arm. In some instance, the first and second arms may be part of a pair of support arms, respectively.

A vertical support provides for the rapid assembly, disassembly, and modification of a shelving system in a variety of configurations, as determined by the practical and aesthetic requirements of the user. The vertical support facilitates the mounting of a variety of attachment members, such as shelves, hangers, or media boards, that contain powered appliances, allowing the user to further customize the shelving system to his practical and aesthetic requirements. The vertical support makes it easy for a user to mount these attachment members and hides the connections of the various components, to maximize the aesthetic appeal of the shelving display. Additionally, vertical support can be configured with other subcomponents to form shelving systems.

A structural connector for assembling a plurality of structural members includes a main shank, a first bolt extending though the main shank, a first plug threadedly engaging a first blot shaft of the first bolt, a second bolt extending through the main shank and the first bolt shaft, and a second plug threadedly engaging a second bolt shaft of the second bolt. Each of two shank ends of the main shank, a first bolt head of the first bolt, a first plug head of the first plug, a second bolt head of the second bolt, and a second plug head of the second plug is configured to threadedly engage a structural connecting end of each of the structural members.

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).

Pedestal components are stacked on top of each other in multiple layers, to form multiple display surfaces at different levels of the pedestal. Modular components may be secured together only by gravitational force, and may cooperate by slidable and/or rotatable engagement, for adjustment of a group of components into different configurations as desired. The pedestal may include two or more subassemblies each having two or more layers of components, wherein the subassemblies may be connected by components extending between and engaging multiple of the subassemblies so that some of the components are common to, and interchangeable in, multiple subassemblies.

A present application is directed to a shelving system having a coupling system comprising a tab coupler and a socket coupler, said tab coupler comprising a locking tab extending from a locking face along a locking axis and configured with a round, T-like sectioned shape; said socket coupler comprising a U-shaped locking socket projecting from a mounting face of the socket coupler along a coupler axis and configured with a U-shaped tab arresting groove; the coupling system is configurable between an unlocked position whereat the locking socket slidingly receives the locking tab so that the locking axis and the coupler axis coincide, and a locked position upon rotating one of the tab coupler and the socket coupler about the coinciding axes, entailing snugly arresting of the locking tab by the locking socket, preventing sliding displacement and axial displacement along the coinciding axes.
