Description

The invention relates to housing frames in skeleton construction for electrical and electronic devices. Such housing frames are required for enclosures, racks, containers, frames and other prefabricated structures that are completely or partially made of metal or metal alloys and for receiving and / or holding electrical and / or electronic sub-racks, chassis and other facilities are provided.

Such housings, frames, containers, frames, and other ¹ ^ prefabricated constructions generally have a skeletal frame with a substantially rigid, upstanding legs of metal or metal alloys. These legs are arranged at a distance from one another on the frame edge and are connected to one another at least on the upper side and on the lower side of the frame in such a way that the frame is made essentially rigid. Furthermore, a lower wall, an upper wall and side walls made of sheet metal (made of a metal or a metal alloy) or made of other sheet material are attached to the frame. At least one of the side walls is usually, but not necessarily, designed in the form of a door. Usually, the upright legs at the top and bottom of the frame are connected to each other by means of rigid support members, each between

adjacent legs extend and permanently or detachably with the adjacent legs, for example with the help by bolts, grooves or by welding. Carry the upright legs as well as the supporting parts contributes significantly to the rigidity of the housing. The .

Support parts also allow a localization of the legs, so that the necessary dimensional accuracy of the frame

is ensured. Usually the support parts manufactured by die casting, from angle steel, from an aluminum extrudate or from a structural foam plastic, as in In all these cases, the mass of the material of the support parts makes a major contribution to the necessary strength and rigidity of the frame.

The invention is based on the object of a simple and inexpensive frame in skeleton construction for a prefabricated Provide construction for receiving and / or holding electrical and / or electronic equipment, the frame being easily and simply assembled by semi-skilled or unskilled workers can be.

The invention is characterized in particular by the features of the claims. The frame can be of any desired cross-section, but is essentially one rectangular cross-section of the frame preferred, with an upright component / arranged at each of the four corners is and the so existing four upright components each on the top and bottom of the • 'Frame are interconnected to give the frame the required To give rigidity. The connection of the

² ^ right-hand components under each other is made with the help of an endless, flexible band and associated stiffeners, anchors or brackets. If the height of the skeletal frame is substantially greater than its transverse dimensions, the upright components can also

to each other with the help of an endless, flexible band and associated stiffeners, struts or brackets at least one middle point between the top and the bottom of the frame are connected.

L -J

Due to the fact that the upright components with each other by endless belts made of metal or metal alloys as well as associated stiffeners, struts or brackets are connected, is the use of support members of large mass to achieve the required rigidity and strength no longer required; Rather, the upright components and the stiffeners, struts or brackets can be made of lightweight material, e.g. steel, so that one has the required strength and rigidity is maintained with a significant reduction in the mass of the material used.

The adjustment devices preferably press the stiffeners, struts or brackets in their longitudinal direction to the upright components outwards to the endless

Keep the band taut. The individual adjustment device • the outward movement of all stiffeners, Struts or brackets are effected at the same time.

For example, the clamping device (clamp, stiffening or bracing) in a skeletal frame with upright To use standing components, in which the cross-sections deviate from one another in the transverse direction, can be done at the outer end each clamping device a nose or head piece can be releasably attached, which is selected from several nose or head pieces whose shapes are different from each other.

The endless, flexible band can move endlessly inwards have directed flange, on which a separately formed lower or upper wall or a separately formed Tray can be releasably attached; preferably the endless flexible belt is integral with one substantially flat, lower or upper wall or with a substantially flat compartment. To the upright components too localize, in both cases the endless, flexible belt can have a second endless, inwardly directed flange on.

Alternatively, the flexible endless belt can stand upright between adjacent ones Components along sections in the longitudinal direction of the tape have an inwardly directed flange, the ends Adjacent flanges provide an opening to receive an upright one Form component.

The invention also relates to a partial kit for producing the above-described frame in a skeleton construction. This set of parts can be packed flat, making them easy to store and transport.

The invention also relates to housings, racks, containers, Frame and other prefabricated structures with the inventive Frame in skeleton construction.

The invention is explained below with reference to the appended Drawing explained in more detail. Show it:

Fig. 1 is a perspective view of the invention Frame and

Fig. 2 is a partially sectioned side view of a clamping device of the frame according to FIG. 1.

The frame shown is essentially rectangular in cross section and has the following components, among others on: four angle irons 1 that support the upright

Form components or legs of the frame, a flexible endless steel band 2, which surrounds the legs below and with

a substantially flat lower wall 3 is in one piece, a flexible endless steel band 6, which the upper end the leg surrounds and is integral with a substantially flat top wall 7 and associated clamping devices 4 and 8, which keep the straps taut in the manner described in more detail below, so that the frame substantially becomes stiff and rigid.

The endless belt 2 has an inwardly directed endless flange 5, and the endless belt 6 has an inwardly directed endless flange 9; the four corners of the Flanges 5 and 9 are used to locate the four legs

The two clamping devices 4 and 8 are essentially identical and each have a central hub 11 and four outwardly extending struts 12. The hub

11 is with a threaded hole 15 having approach 14 and an annular recess 16 provided, the Diameter gradually directed away from the base of the recess increases. In the recess 16, a conical bolt 17 is slidably or displaceably arranged, the shape of which is complementary to that of the recess. A screw 19 extends through a bore 18 in the bolt 17 and is in engagement with the threaded hole 15 in order to push the bolt 17 axially into the hole 16. Any bracing

12 consists of an extruded steel tube, the 'inner end of which is free in one of four in the circumferential direction Spaced, radially extending bores in the wall of the extension 14 slides. The inner end face each strut 12 is shaped so that, when flush with the inner end of the bore 20, it forms the outer wall the recess 16 continues smoothly. At the outer end of each strut 12 is a separately formed nose or Head piece 21 releasably attached, which is convexly curved at its free end and complementary to the concave shape of a Leg 1 is; the nose or head piece 21 has a

Pin 22 which protrudes through a slot 23 in the leg 1 and into a bore in an L-shaped corner piece 24 engages, which is arranged between the leg 1 and the band 2 or 6, around the strut relative to the leg to be forcibly secured.

During the production of the skeletal frame, the struts 12 of the lower clamping device 4 are in bores 20 of the projection 14 of the hub 11 arranged, the conical

.jQ bolt 17 is removed, and the clamping device is in the Endless belt 2 arranged. When the separately formed corner pieces 24 at the corners of the endless belt 2 and the legs 1 are arranged at the corners defined by the flange 5, the pegs 22 of the nose or head pieces 21 of the struts 12 inserted through the slots 23 in the legs and come with the holes in the corner pieces forcibly engaged; the conical bolt 17 is pressed into the projection 14 with the aid of the screw 19, so that the arrangement is loaded to a small extent. The screw is then tightened down to tension the band 2 and to effectively clamp the lower ends of the legs 1 between the band and the struts 12.

The same process flow is used for the top of the. skeletal frame repeated.

Once the skeletal frame has been clamped or braced to form an essentially rigid structure, so the bottom, the top and the side walls can be clad with sheet metal (the sheet metal can be shaped like this be that the legs 1 and the connecting parts are covered); a hinged door is also fitted.
