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.

According to the invention, a connecting element (1) is provided, comprising a base plate (2), which is connected to at least a first receiving element (3) and a second receiving element (4), wherein the first receiving element (3) and the second receiving element (4) each have a first strip (7) and a second strip (8), which are each arranged substantially perpendicular to the base plate (2), wherein the first and the second strip (7,8) of the first receiving element (3) and the base plate (2) delimit a first receiving groove (9), which is designed to receive a separating element (23), and the first and the second strip (7,8) of the second receiving element (4) and the base plate (2) delimit a second receiving groove (10), which is designed to receive a separating element (23).

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.

An angle bar includes two longitudinal angled plate portions, and a corner portion connecting therebetween. The corner portion has an inner corner surface bounding an inner corner space and an outer corner surface. A stopper protrudes into the indented corner space, and has an abutment face extending across the indented corner space. A limiter protrudes into the indented corner space from the inner corner surface, and has a through hole opening in a direction along a bending line of the corner portion. A modular post assembly has at least two angle bars abutting each other, and a fixing rod extending through the through holes of the bars along the bending line and limited between the stoppers for fixing together the bars.

A bar for supporting a table, comprising includes an angle shaped bar having a longitudinal extension, including a first side and a second side extending perpendicular relative each other, at least one first hole through the first side of the angle shaped bar, adapted for connecting two bars together longitudinally so as to form a longer bar, a ridge, extending along the longitudinal edge of the first side of the angle shaped bar, wherein the ridge is adapted to longitudinally limit movement of connected bars.

An adjustable shelf system includes a vertical support member with slots therein, brackets each having at least one rearward hook engageable into a said slot, a shroud behind and about opposing sides of the vertical support member, and a cover member separable into strips configured for placement over the front face of the vertical support member and mateable with the shroud above and below the brackets.

The present invention relates to an adjustment profile (11) comprising an elongated means, substantially square of its cross section which means is provided with evenly spaced fastening openings (13) on at least one of its surfaces for receiving fastening means. In the cross section of this adjustment profile, one of its four sides is open for the whole length dimension of the adjustment profile comprising two opposite edge profiles (12) shaped substantially symmetrical to form a linear guide. Between the two opposite edge profiles (12) forming this linear guide is here arranged a moving carriage (16), whereby the motion of the carriage is supported by at least two bearing units (18) supported on opposite edge profiles.

Disclosed is a planar exterior forming square rack pipe, which comprises a rack pipe main body, a joint coupling protrusion part, and a plane forming member, and thus the outer surfaces of the planar exterior forming square rack pipes can be simply formed as a plane without operations such as the attachment of a separate member, such that the coupling of additional objects to the outer surface of the planar exterior forming square rack pipe such as the assembly of a planar panel, the mounting of a shock absorber, the mounting of a name plate, and the fastening of angles is simplified, assembly and mounting for the coupling of the additional objects can be completely carried out, and external foreign material such as dust can be blocked, and the rigidity of the exterior of the planar exterior forming square rack pipe can be reinforced relatively more than that of a conventional rack pipe having a curved shape so as to allow the rack pipe to be used as a pillar for supporting heavy materials or receiving a heavy load, thereby enabling stable support.
