A modular rack assembly includes upright support legs, two first shelf units, and a second shelf unit. Each upright support leg has two spaced-apart first hole units, and a plurality of spaced-apart second holes disposed between the first hole units. The first shelf units are connected to the upright support legs through the first hole units. The second shelf unit is engaged to the second holes of the upright support legs which are at the same height, and includes a second shelf plate formed with insertion holes, and supporting members that are engaged to the second holes at the same height and that are inserted into the insertion holes to support the second shelf plate.

A wall hanging system by which a wall décor item such as a ledge, a frame, a mantel, or the like may be mounted to and hung from a wall. The wall hanging system may include the wall décor item having a rear surface and first and second mounting channels in the rear surface. The wall hanging system may also include first and second mounting brackets that are configured to be mounted to the wall. At least one of the first and second mounting brackets may have an elongated aperture through which a fastener extends for mounting that mounting bracket to the wall. As such, the mounting bracket with the elongated aperture is able to slide side-to-side along the wall while being mounted to the wall in order to properly align the first and second mounting brackets with the first and second mounting channels of the wall décor item.

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 screw includes a head having and a stem with spaced apart threads. The thread of the thread of the screw includes flat spots and sloped section, and is sized, such that it can securing attach through a hole in the pegboard without damaging the hole despite the thread being wider than the hole.

A rack storage unit for use in an automation system for a storage of work pieces and/or work piece pallets and/or tools, which includes a base frame with a rack stand and two rack side parts arranged at a distance from one another, wherein facing surfaces of the rack side parts are provided with interfaces for mounting placement devices. It is provided that the base frame is produced as a one-piece cast body from artificial stone, and that the interfaces are held by adhesive force as separately formed insert parts in the facing surfaces of the rack side parts.

The invention relates to system for the mounting of shelves on a substantially rectangular load carrier having four identical columns arranged in the corners thereof. The system comprises columns having a rectangular profile with four side faces, a substantially rectangular shelf of a length which is shorter than the distance between the columns of the load carrier, on which shelf a holder is mounted that can be inserted into complementary slots in the columns of the load carrier, said slots being configured with a support face with which the holder is capable of engaging in such a manner that the holder supports on the column. The columns as such are configured with slots that extend symmetrically about a longitudinally extending center axis of one of the side faces and through the side faces adjacent to that side face. The slots are each separately configured with three substantially identical cut-outs, the one of which is situated in the axis of symmetry and the two remaining ones are in the adjacent side faces. The cut-outs are function as support faces for the holders of the shelf, them being arranged on the shorter sides of the shelf and extending in the longitudinal direction of the shelf to the effect that they are capable of engaging with the slots in the four columns arranged on the load carrier.

A system to support a member extending from a wall. The system includes a wall with one more apertures, a bracket configured to be disposed an aperture, and a member comprising a tang, wherein the tang is configured to be supported by the bracket. The bracket comprises a body with a hole, the hole receives the tang therein, wherein the body comprises a plurality of surfaces that collectively define the hole, wherein the body includes a portion biased inwardly toward the opposite surface, wherein the biased portion extends inwardly past an inner surface of the respective wall of the plurality of walls that includes the biased portion. The body further includes a plurality of fingers extend from the plurality of walls, the plurality of fingers each biased in a direction away from the hole.

A shelf system for mounting a shelf to a wall, which includes a shelf having a rear edge and first and second shelf fasteners coupled to the shelf and protruding from the rear edge. The shelf system may also include a mounting bracket assembly for mounting directly to a wall and to which the shelf is to be coupled. The mounting bracket assembly may include first and second shelf engaging portions that have mounting apertures therethrough. Wall fasteners may extend through the mounting apertures of the first and second shelf engaging portions to mount the mounting bracket assembly to the wall. The portions of the first and second shelf fasteners which protrude from the rear edge of the shelf may be inserted into the mounting apertures of the first and second shelf engaging portions of the mounting bracket assembly to couple the shelf to the mounting bracket assembly.

A mounting system that includes a hub which is fixable to a surface to aid in hanging an object on the surface. The wall mount system allows for various applications depending on the item being mounted and/or the preference of the individual mounting the item. The hub is configured to support the use of disparate fasteners, affording a user flexibility to choose between various wall fastening options and combinations therein depending on the application.
