An assembly for use with a weight rack includes a mounting rail for mounting to the weight rack, including a plurality of rail sections extending laterally and spaced along the length of the mounting rail to define slots therebetween. The accessory includes a mounting portion for removably mounting to the mounting rail and a functional portion connected to the mounting portion for use in a weightlifting exercise. The mounting portion includes a fixed portion and a moveable portion that is moveable with respect to the fixed portion between a locked position, where the fixed portion and the moveable portion engage the mounting rail, and a release position, where the accessory can be removed from the rail. The mounting portion also includes a peg received in one of the slots of the mounting rail and a locking mechanism that moves the moveable portion between the locked position and the release position.

Four types of telescoping modules are disclosed wherein the first type has a pair of opposed female ends, the second type has a pair of opposed female ends, and the third type has a female end and an opposed male end. The fourth type has two opposed male ends between which a positionable threaded rod and retaining components stably extend the length between the male ends of the telescoping module. Alternatively, the fourth type of telescoping module may have a female end and a male end. Each of the male ends of the second, third, and fourth types of telescoping modular components comprises a cylindrical body with one or more linear set(s) of two or more spaced-apart prongs on the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels and/or prong-retaining slots for receiving therein the cylindrical body.

The application relates to a method of establishing four profiles which when releasably mounted together are forming a cabinet frame. The profiles are having folding areas comprising cutout parts.

In a wall-mounted shelving and/or storage system, vertical standards are mounted to a wall using a plurality of individual cleats arranged in vertical columns and horizontal rows. The width of each cleat is smaller than the width of the standard, so that it can be hidden within the standard when mounted. Formed on the back of each vertical standard are a plurality of transverse edges at predefined intervals, in known spatial relationships with bracket connection points, for cooperating with the cleats to properly position and orient the standards at the correct height with respect to each other.

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).

A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.

A tubular structural profile and construction system, produced by cutting and folding a semi-rigid and foldable sheet, having four orthogonal layers joined at fold lines and two internal diagonal layers joining two opposing fold lines. The sheet has six rectangular sections. The cutting lines are positioned for at least one tongue, which coincides with at least one slot located on an opposing fold lines, such that, during the folding, the profile is closed of the coming together of fold lines and both internal diagonal layers, and by means of the insertion of at least one tongue on its corresponding slot, and wherein, in addition, the profile of the formed system can have at least one break in the second external layers and in the two internal diagonal layers, which permit the creation of an engaging area for transverse structural profiles.

A modular tube apparatus that can include metal legs as an inner part of an overall height adjustable leg of a workstation. Each leg piece can include a plurality of protrusions on each side to help align parts for assembly and vertical shear strength. There are also notches on each side to self-align holes on the two parts and for additional shoulder support. The overall adjustable legs may include a base plate for securement and an outer tube leg to provide additional strength and securement.

Provided is an angle bar for shelf assembly, the angle bar including a vertical frame in which a plurality of fastening grooves is formed and a horizontal frame on which a fastening protrusion is formed, wherein the plurality of fastening grooves, each including upper and lower grooves, are formed, the lower groove has a narrower width than the upper groove, and is connected to the upper groove with an inclination portion in between, wherein the fastening protrusion includes a convex portion having an inclination surface and first and second wing portions that are formed on lateral surfaces, respectively, of the convex portion, and wherein a distance between respective end portions of the first and second wing portions is smaller than a width of the upper groove and is larger than a width of the lower groove, and the convex portion has a wider width than the lower groove.
