CONSTRUCTED FROM SPECIAL CROSS-SECTION BARS The following statement is a full description of this invention, including the best method of performing it known to applicant(s): P19/3/84 Partition element for insertion into the side openings of a housing frame, constructed from special cross-section bars.

The invention refers to a partition element for insertion into the side openings of a housing frame, constructed from special cross-section bars. Such a partition element is basically known from the German utility model 7508449.

In case of the known partition element the locking mechanisms, with which the partition element is connected to the housing frame, protrude through the internal side of the housing of the wall element, wha- often a disadvantage. For reasons of cleanliness and hygiene, especially in the field of medicine, smooth internal walls are desired for the housings built from 15 partition elements. The protruding locking mechanisms could ha%4 a disadvantagous effect also with regard of flow technology, if the housings are used as channels for a flowing gas. A further disadvantage of the known partition element is in that, that the cts internal and external wallj pate of the partition element must

C

be bent at their edges, thereby making heir manufacture expensive.

Further, the achievement of a possibly good thermal and/or acoustic insulation of the interior of the housing from the 25 surroundings is often important. In case of the known partition element bridgings, transferring heat and sound are in existence, which are formed by the locking mechanisms and often through the direct contact between the internal and external sheets of the partition elements.

of the type mentioned in the introduction, which continuous smooth internal housing sur nd which can be simply manufactured. Further partition element should be constructed so, th eferably no well conducting heat and sound co ons should be present between the internal and -i =e -a--54 &g pa t-i- il e-1--1ti rtL: -3a- According to the present invention there is provided a partition 'lement for insertion into the side openings of a housing frame, whose side openings for the support of the partition element are each bordered by a continuous bearing flange which can be grasped from the back, said partition element having an external plate and an internal plate which are separated by a space filled with insulating material, said partition element being provided with locking mechanisms near its edges by which the partition element is lockable with the housing frame, characterized in that the partition element along its outer periphery consists of special cross-section bars which are adjacent to each other, and have o.

on their sides parallel to the sides of the partition element |I flat surfaces, so that the external plate and the internal plate, both smoothly formed, are fixed to the flat surfaces i of the special cross-section bars and that the locking I mechanisms are arranged inside the special cross-section bars and are each provided with a locking bolt which can swing outwards from the narrow side of the partition element.

V.

Figure 1 shows a corner of a cube or a rectangular shaped housing, which is constructed with partition elements in accordance with the invention. The housing frame consists of housing frame bars with special cross-section 6 three of which, cut at bevel, converge in each corner. These are held together by a corner piece 69, from which three connecting pieces protrude at right angle to each other, onto which the housing frame bars with special cross-section 6 are pushed.

The connection between the bar with the special cross-section and the corner piece can be carried out by gluing, bolting or riveting, for example. Each housing frame bar with special cross-section has two bearing flanges 63, arranged at right angles to each other, which can be grasped at the back (see Figs. 2 and which in case of an erected hovsing frame forms a continuous bearing flange, against which a partition o element abuts with a corresponding bearing flange 22.

ao A partition element is constructed from four special S. cross-section bars 4 which are cut at bevel and are joined as a square or rectangular shaped frame. The external wall and the internal wall 18 (Fig. 4) of the special cross-section bar show smooth surfaces 7 and 8, respectively, plate P\te onto which the external e1 2 and the internalqal 3, °o which as an example may be made of aluminium sheet, are glued by means of a double-sided adhesive tape 9. The adhesive S tape is preferably an elastic synthetic material and has a certain thickness of, for example, 0.8mm so, that thermal .stresses between the various components of the partition element can be compensated due to the elastic deformation of S this layer of adhesive band.

The connection between the four special cross-section bars can be produced exclusively by this adhesive tape.

However, in case of large and/or heavily loaded partition elements additional metal angles can be set inside the special cross-section bars at the connecting positions where they border each other.

39 -3e\r The space between the two4pmae-2 2 and 3 is filled out with insulating material, for example with mineral fibre-wool.

on Fig.4 shows an example of embodiment of a sectioned special cross-section bar for a partition element. The hollow section contains two intermediate walls 16,17, so that three chambers 11,12,13 are formed. One can recognise both smooth surfaces 7 Sp\ate.

and 8, respectively, to which the externalqpaeed 2 and the p\ze. internal4 ae4-e 3, respectively, are glued. The wall 19 of the special cross-section bar, which forms the narrow external side of the partition element, is provided at both its ends with a projection 19a,19b, which form a stop-edge for the to-be-glued phates p\otes -on paq-ss 2 and 3 and facilitate the adjustment of the pal-e4during the gluing process. The bearing flange 22 is formed by a -6 section protruding at right angles from the wall 19 of the S* special cross-section bar by which the bearing flange 19 is mechanically stiffened on one hand, and on the other a i completely smooth external surface of the partition element is achieved. However, in principle, a simple protruding from the 20 wall 19 of the special cross-section bar wall would suffice as bearing flange. The bearing flange 22 is provided with a groove 23 to accept a seal 24. This seal is constructed preferably as a .I highly effective double-lip rubber seal, which seals reliably the inside space of the housing for both vacuum and pressure.

The locking mechanism 40 for tW+e fixing .4 the partition element on the housing frame consists of a locking bolt 41 and an actuating shaft 42 for te turning a4 the locking bolt. The intermediate walls 16 and 17 of the bar with special crosssection 4 are positioned so, that the leaf-shaped locking bolt 41 is guided between the long side walls of the chamber 12 and is fixed by these in its position at right angle to the plane of the wall element. To retain good guide surfaces for the locking bolt 41, both long walls of the internal chamber 12 are provided with projecting webs 14 which during the milling of the slots 44 are also milled to the exact dimension for the locking bolt.

7 These webs also serve for good anchoring of the above mentioned possibly used stiffening at the connecting positions of the bordering special cross-section bars, while the stiffening angle is inserted in the chambers 12 of the special cross-section bars.

Theused in the example of embodiment ma- for the locking bolt consists of a first cylindrical section 43a (Fig.6a and 6b), a cam-shaped portion 43b and a second cylindrical section 43c. The cam-shaped portion is constructed as a square and fits into the corresponding square hole of the locking bolt 41. The actuating shaft is mounted with its first cylindrical section 43a in the corresponding holes of the external wall 15 and the intermediate wall 16 and with the *6 second cylindrical section 43b in the second intermediate S wall 17.

*see The assembly of the locking mechanism 40 is carried out in such j a manner, that a short slot 44 (Fig.4) is milled into the wall S2b 19 of the special cross-section bar, through which the locking bolt is pushed into the chamber 12 from the narrow side of the partition element. Subsequently, the actuating shaft is pushed from the front side of the partition element into the position shown in Fig.3. A falling out of the actuating shaft is prevented by the outer plate 2. The actuating shaft is provided with a preferably square-shaped axial hole or continuous conduit 39 so, that by inserting a square-shaped key from the outside through an opening in the outer4Apse 2 the locking bolt can be turned so that it swings out through the slot 44 in the special cross-section bar and shifts behind the bearing flange 63 of the housing frame bar with the special cross-section and the partition element pushes strongly with its seal against the bearing flange 63 of the housing frame bar with the special cross-section.

To achieve a high heat transfer resistance at right angle to the plane of the partition element, the special cross-section bars of the partition element can be made of poor heat conducting synthetic material, preferably with glass fibre reinforcement.

shows in cross section the possible construction of a special cross-section bar in the case when this has to be made of metal, but the heat conductivity at right angle to the plane of the partition element has to be low. The special crosssection bar in this case consists of two bar sections 4a and 4b, the first one of which forms both chambers 11 and 12 to accomodate the locking mechanism. The second bar section is an essentially smooth wall portion 18, which is connected with the J. first part by two insulating web-walls 20. The web-walls are dovetail shaped at their ends. Another possibility of their S construction is to bend them at their ends as it is shown for the insulating web-walls 65 of the housing frame bars with l special cross-section in Fig.2.

S 2' 0 On the sides of both bar sections connected by the insulating U- web-walls there are correspondingly shaped protrusions 26,27 to accomodate the insulating web-walls. Firstly, the relatively narrow protrusion 26 of the extruded bar section is bent to a lesser degree and is pressed against the insulating web-walls connection.

S actuating member 45 could be provided instead of a square-shaped 0 3 key, as this is illustrated in Figs.7a and 7b. This actuating member consists of a spindle 47, one end of which is constructed as a slotted square 46, on the tip of which locating lugs 46a are situated. This square is inserted into the square-shaped hole 39 of the actuating shaft 42 and is located with the locating lugs 46a behind the internal face of the actuating shaft 42 so, that the actuating member cannot be removed -6i ir;; i once the housing is closed. On thejprotruding through the partition element l 7I, star-shaped for example, handwheel 48 can be put on fixed or rotatably. In the porflet of e s 4p7ne 17 latter case the4protruding through the partition element *r r i 0L:- 47 is constructed of two cylindrical sections 47a,47b, having different diameters so, that the hand wheel 48 with its correspondingly shaped hole section is fixed in the axial direction by the smaller diameter. An actuation of the locking bolt 41 is possible only then, when the hand wheel 48 is connected with the spindle 47 in the direction of rotation. For this purpose on the face of the top cylindrical section 47a there is a slot 49 situated, and in the upper part of the bore in the hand wheel 48 there are two axially running diametrically opposed grooves 52. By inserting a correspondingly shaped flat key 51 into the slot 49 and the grooves 52, the hand wheel 48 and spindle 47 are connected with each other in the direction of o* rotation so that an actuation of the locking mechanism becomes possible.

26 The above described partition elements can be varied in many ways within the framework of the claims. For example, the chamber 13 in Fig.4 may be omitted and the intermediate wall 17 may take the function of the directed towards the internal side of the housing external wall 18. A protrusion of the cylindrical section 43c of the actuating shaft 42 from the intermediate wall 17 is not necessary. The second cylindrical section 43c of the actuating shaft 42 of the locking mechanism can also be omitted completely.

The thickness of a partition element can be, for example, 40 mm p\ c,.fs and the span up to 2 to 3 meters. The I paeas 2,3 have, for example, a thickness of 1 mm.

The number of required locking mechanisms per partition element depends from the size of the partition element and the required quality of the seal.
