The wheel and axle assembly is removable from the strut assembly and when utilized and assembled on the strut assembly the wheel and axle assembly is in an extended position to provide stability of the cart.

In a framework made of frame pieces for a switchgear cabinet, the frame pieces are preferably laterally reversed in relation to their cross-sectional diagonal.

Each frame comprises, on one first side, posts (11A to 11D; 11A' to 11D') and, on a second side, crosspieces (12A to 12C; 12A' to 12C'), said posts and crosspieces extending perpendicularly to one another when the frame is assembled.

In a framework made of frame pieces for a switchgear cabinet, the frame pieces are preferably laterally reversed in relation to their cross-sectional diagonal.

The self-supporting span (l, 2) has fixed thereto one or more auxiliary posts and crossbars (3) for supporting filling modules (C) for the wall.

In the area of the inner side of the framework, the frame pieces have two receiving sections provided with fastening recesses for fixing mounting rails.

An important place in our façade systems is occupied by the mullion-transom wall MB MB-SR50N.

The supporting structure of the MB-SG50 system is based on a mullion/transom aluminium frame of the profile width equal to 50 mm.

The invention relates to a control device with a housing (10), the open front of which is fitted with a closed front frame (13) consisting of frame arms (14, 15, 16, 17) and corner connectors (18).

Like Emile Gallé, Louis Majorelle took his inspiration from the outlines of plant forms for the base, uprights and crosspieces in his furniture.

The invention relates to a supporting structure for conservatories or the like, especially the frame profiles used for the same, that is the vertical members and the bars which carry the glass structure.

By combining several known and novel features, a framework having easy-to-produce frame pieces is created which optimally meets all requirements for use with a switchgear cabinet.

The MB-SR50N mullion-transom system is also a basis for fire resisting façades MB-SR50N EI and glazed roofs.

The invention is characterised in that the struts (7, 8) have detent devices (10) and can be interlocked by means of said devices, to form the rectangular frame when mounted.

A guarantee of solidity and a perfect aesthetic, the fluted feet are joined by a crossed spacer; the uprights and sleepers are supported by an assembly of tenons and mortises.
