A frame structure (100) for a piece of furniture comprising struts (1) which are capable of forming legs (101) of the piece of furniture, cross-pieces (2) which connect, in accordance to a grid-like structure, the struts (1), and connection means (300) which are configured to join the struts (1) and the cross-pieces (2), wherein the connection means (300) comprise at least two bent extensions (21, 22) which are capable of engagement in corresponding seats (11, 12) which are formed in the strut (1) and in the cross-piece (2), respectively, or vice versa, and further comprising a fixing element (3) which includes an abutment surface (30), a threaded seat (31) and a corresponding screw (4) which has a head (40) which is capable of an approach movement towards/withdrawal movement from the abutment surface (30) by means of screwing in the threaded seat (31), the fixing element (3) being configured in such a manner that the abutment surface (30) and the head (40) of the screw (4) abut the strut (1) and the cross-piece (2), respectively, or vice versa, as a result of the mutual approach/withdrawal movement.

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.

The “STRUCTURAL PROFILE FOR ELECTRICAL CABINET” comprises a profile that presents a front sealing area and is positioned in relation thereto at 90°, a side sealing area, an inner fixing wall, an inner fixing side, an inner fixing tab, an outer fixing wall, an outer fixing side and a central barrier.

Generally, an enclosure and method for assembling an enclosure including a plurality of frame members connected or interconnectable to generate a framework and a plurality of panels fastened or fastenable to the framework. In particular embodiments, enclosure and a method of assembling an enclosure from a kit including prefabricated enclosure sides including interconnectable frameworks fastened to panels configured to overlap adjacent panel edges at the corners upon interconnecting the frameworks.

STRUCTURAL COLUMN AND MODULAR STRUCTURE FOR ELECTRICAL CABINETS COMPRISING SAID STRUCTURAL COLUMN, includes a structural column (1) which, from a single piece, accurately determines two corners or vertexes of a modular structure (19) for electric cabinets. The modular structure (19) has four vertically positioned structural columns (1) and at least eight horizontal beams (20) connected to each other by means of screws (21). This invention also introduces an innovative joint between the elements of the structural columns (1), which are joined together by means of welds (6) and with the aid of limiters (12), positioning flaps (11) and engagers (9). Thus, this invention guarantees a perfect square of the modular structure and the correct assembly of the electrical cabinet, with no need for highly specialized labor. The modular structure (19) presented here can be manufactured entirely from low-cost metal materials such as carbon steel, significantly reducing the manufacturing costs of electrical cabinets.

A mast arrangement for a storage and retrieval unit is disclosed. The mast arrangement includes a mast, which is formed by a front flange plate, two side plates and, a rear flange plate and has a box profile and a substantially rectangular cross section, interface elements, which are each secured in pairs to the side plates and extend in the region of the front flange plate, and a rail for guiding the storage and retrieval unit. The rail is attached to each of the interface element. The interface elements are each provided with a hole, a reinforcement element extending through the hole, and through corresponding holes in the side plates, and are connected on both sides to the relevant interface elements.

Provided is a coupling system comprises a first tubular member with a top end and a second tubular member with a bottom end, defining together a longitudinal axis. One of the top end of the first tubular member and the bottom end of the second tubular member is configured with a longitudinal axially extending socket portion. The other one of the top end of the first tubular member and the bottom end of the second tubular member is configured with a longitudinal axially extending plug portion for coaxial snug receipt within the socket portion. Each tubular socket portion and the plug portion is configured with a lock opening intersecting the longitudinal axis. The coupling system includes a locking plug configured for locking engagement of the lock openings while in register with one another, thereby preventing axial or rotary displacement of the first tubular member and the second tubular member.

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.
