Description

STRUCTURAL MEMBER FOR A CABINET FRAMEWORK IN SWITCHING The invention relates to a structural member for a switching cabinet frame, which has two profiled sides that rest vertically towards each other, forming the outer sides of the frame, and which are designed as a section of hollow profile that is open to the inner side. The structural members, designed as closed hollow profiles, are known for the structure of a switching cabinet frame. Closed hollow profiles are expensive to manufacture, particularly when they satisfy in a simple manner all the requirements made of a frame, the possibilities of a full length assembly, the simple connection with the corner connectors, the sealing of the elements of wall and the doors to be coupled, etc. Structural members for a switch cabinet frame are also known, designed as open hollow profiles, which may be simpler to be manufactured with a stamped and flexed part, but which do not meet in a simple manner all the requirements of a frame of switching cabinet. The purpose of the invention is to provide a structural member of the aforementioned type, which, like a hollow profile section fabricated in a simple manner, satisfies in a simple manner all the requirements made of a switching cabinet frame. This objective is achieved according to the invention by combining the following characteristics: a) the sides of the profile are fused one inside the other via transition sections that remain vertical towards each other, inside a corneal section that remains at an angle of 135 ° towards both sides of the profile, b) the sides of the profile are fused one inside the other, opposite the transition sides, within externally open receiving grooves for sealing elements, c) the connection with the receiving grooves are sections that lie vertically parallel to each other. the associated profile sides, d) the sections are parallel to the associated profile sides are provided with a series of coupling means, and e) the connection with the section that is parallel to the associated profile sides are terminal sections curved inwards.

The structural member thus designated can still be manufactured from a simple curved and stamped part or as an extruded section, or by profiling or stencil cutting. The profile sides of a structural member with the reception grooves curved inward, offer accommodation possibilities for the sealing elements, which can also be designed as high frequency seals. The transition sections and the connecting section provide in the region of the outer edges a receiving means in which the hinge and closure means can be housed. Symmetrically with the diagonal of the cross section, in the end regions of the structural member, two plug-in receiving means are formed for plug-in groups of corner connectors, so that the frame structure can be easily assembled with the structural members, and with the correspondingly designed corner connectors. Both rows of coupling means form, turned to the internal phase, two coupling strips lying vertically towards each other, so that the components can be coupled to the structural member in two directions. The structural member of that type is stamped and folded from a metal foil strip or is produced as an extruded section. According to a development, the possibility of coupling with the corner connectors occurs because the sections that remain vertically towards and parallel with the associated profile sides define, with the reception grooves and the terminal sections, the receptacle receiving means for plug-in groups of corner connectors. The receiving grooves on the profile sides are formed by three sections which are respectively at right angles with respect to each other. According to yet another embodiment, the transition of the receiving grooves to the continuation sections is constructed so that the sections lie vertically towards the profile sides, they are formed with sections of the grooves receiving one way in two layers. Furthermore, the transition section and the connecting section form, towards the outer edges of the hollow profile section, a reception means for folded edges above, wall elements or a door. The plug-receiving means for the groups of plugs or the corner connectors are improved since the terminal sections lie vertically towards the connecting section or vertically towards the sides of associated profile. The design of the structural member can be such that it is in the form of an open hollow profile section, or as a closed hollow profile section. The invention will be explained in more detail with reference to the modalities given by way of example and shown in the drawings, which show: Figure 1: a structural member in cross section, as an open hollow profile section, and Figure 2: a perspective view of a portion of a structural member in the form of a closed hollow profile section.

The structural member according to FIG. 1 is produced, for example, from a metal sheet strip by stamping and bending as an open hollow section section 10. The hollow section section 10 does not have an outer edge formed, but nevertheless forms asymmetrically to the diagonal. During assembly of the structural member, the open side of the hollow profile section 10 is turned inwardly. The two profile sides 11 and 12, which lie vertically to one another, form the outer sides of the structural member in a known manner, but do not extend as far as the outer edge. These are interconnected by the transition sections 14 and 15 that remain vertically thereto and by the connecting section 13. Thus, in the corner area there results a receiving means 30, which houses not only the hinge and closure elements. , but also the folded edges 41 and 43 of the doors 40 and the wall elements 42. Facing away from the transition elements 14 and 15, the sides 11 and 12 of the profile are fused into reception grooves 17 and 17, in shape of U, formed by three sections that remain respectively at right angles to each other. These receiving grooves 16 and 17 house sealing members 31 and 32, which limit against the lips or sealing lips on the walls 41 and the wall elements 42. As shown by the sealing strips 33, the sides 11 and 12 of the profile can by themselves support the sealing strips, which is particularly useful for alignment of the structural members. By connecting with the receiving grooves 16 and 17, the sections 18 and 21 are inwardly curved towards the sides 11 and 12 of the profile, being in a double-layer shape with the adjacent section of the receiving grooves 16 and 17. connection to sections 18 and 20 are sections 19 and 22, which are respectively parallel to the associated sides 11 and 12 of the profile and are provided with a series of coupling means 24 and 25. Finally, terminal sections 20 and 23 connecting with sections 19 and 22 form, with sections 18 and 19 or 21 and 22 and receiving grooves 16 and 17, receiving means 26 and 27 for the plug assemblies of the corner connectors, as shown in the broken lines. The end sections 20 and 23 are aligned parallel to each other, and lie vertically to the connecting section 13. These can, however, be vertical to the associated sides 11 and 12 of the profile as well, and better surround the plug-in groups of the connectors. corner. Sections 19 and 22 form, with their rows of coupling means 24 and 25 over the entire length of the hollow profile section 10, the coupling means in two seals that lie vertically to each other. In this case, the additional mounting rails can be simultaneously connected to the sections 19 and 22, reinforcing the hollow profile section 10.

In the embodiment according to Figure 2, a structural member 10 is involved, formed as a closed hollow profile section, which may for example be produced as an extruded section. The difference of the structural member 10 according to figure 1, lies in the fact that the terminal sections 20 and 23 lie vertically to the connector section 13 and are interconnected by a section 28. This section 28 can be connected to the connecting section 13. The section 28 may also comprise sections in two parts, which are connected to the terminal sections 20 and 23. The receiving means 26 and 27 for the socket groups of a corner connector may in this case also include the sides 11 and 12 of the profile and the transition sections 13 and 14. However, two receiving means remain for two plug groups, although with different cross section. In addition, the structural member according to Figure 2 satisfies all the requirements made of a structural member.
