Description: PART OF FACADE, PARTITION WALL OR EQUAL CONSTRUCTION WHICH CAN BE USED ON BOTH SIDES, AND MOUNTINGS FOR THIS FACADE The present invention relates to parts of facades, partitions or the like which can be used on both sides, that is, whose sides are equipped with properties rendering it attractive to be able to turn the part in its support, for example, in the form of a frame. The present invention also relates to hardware for such swivelling or pivoting parts, more specifically pivot and swivel mountings, optionally with friction elements, and also fittings which facilitate the swivelling or pivoting of the parts. The following description of the invention will be based on these parts beings windows, doors or combinations thereof, but this is only a preferred embodiment and it also conceivable that the parts, for example, may be components of a decoration or the like, A great number or more or less complex devices are known in the art for at least partly turning windows so as to make the outer surface accessible for maintenance from the inside of buildings. Of course, the aim has been to turn the window as close to 180° as possible to allow easy access for maintenance. However, in the cases where the pivoting has taken place through virtually 180°, the general plane through the window has been displaced so as to lie outside the general facade plane, whilst windows using the other conventional pivot means can only be turned approximately 180°. Today's building technology uses, not least when it comes to cladding glass, highly specialised windows of double or multilayer type and having a sophisticated system of coatings sometimes with highly selective reflection and transmission properties. Of course, the object of these energy-efficient windows is to maximise or optimise both the transmission and reflection of heat and light. It would be of great interest to be able to produce a window which could be used "on both sides" in order to be able to utilise the properties of the window as regards the transmission and reflection of light and heat, not least when climatic conditions vary, but not restricted thereto. At the same time, it would be of great interest to be able to produce a window which in one or two simple movements and without excessively complex hardware and framework can be turned 180° to facilitate maintenance. In addition, it would be of great interest to produce windows where the swivelling or pivoting could take place horizontally, vertically or, if so desired, at any angle whatsoever. As mentioned above, it should be noted that the invention is not limited to windows, but generally relates to swivelling or pivoting parts of facades, partitions and the like, for instance, also doors or combinations of windows and doors, and also purely decorative elements. However, as mentioned, the invention will be described here with particular reference to windows. In the description that follows and in the accompanying claims the word 'frame' is used to mean the surround of the aforementioned parts of facades, partitions or the like, whilst the word 'casing' is used to mean the framework around the opening that the part is intended to close. In accordance with the above, the present invention relates to a part of a facade or partition useful on both sides and capable of swivelling horizontally or pivoting vertically through 180°, characterised in that it comprises: a) replaceable casing/frame fittings /plates; b) a concealed hinge mounting, optionally having friction elements, located in the centre of the casing/frame cross-section; c) a surrounding, U-shaped friction moulding or section on both sides of the mounting; d) a surrounding air duct in the internal groove of the frame with vents between the U-shaped mouldings; and e) a replaceable opening device for turning the mouldings In a preferred embodiment the frame consists of two identical parts joined together with tongues and grooves and secured to one another with screws from each side. It is preferred that the U-shaped mouldings should be secured by means of inlaid, stripping tacked or stapled in place. The inventive part is preferably a window, a door or a combination thereof. It is preferable that the space between the frame and the casing should be 3.2 to 20 mm. As stated above, the invention also relates to a swivel or pivot hinge mounting, optionally equipped with friction elements, for swivelling or pivoting the part of the facade, partition or the like 180°, and this mounting is characterised in that it comprises: a clamping plate for the casing or frame, a clamping plate for the frame or casing, a space-adjustable plate or arm for retaining an anchor bolt and optionally adjusting the friction, and a pivot bolt, optionally equipped with friction elements. In a preferred embodiment, an adjustable friction or braking element in a housing is provided between the bolt and the arm or plate, wherein the friction or braking element consists of optionally slightly conical discs or washers, alternately secured by the housing and the bolt and optionally pressure-loaded by means of a spring. In another preferred embodiment, the bolt is in the form of a double screw which, reckoned from the head, comprises a threaded portion of relatively large diameter, intended for interaction with an adjusting nut for loading the spring, a square-cylindrical portion for retaining the washers and whose diagonal dimension is smaller than the diameter of the central hole in the washer, and a threaded portion of relatively small diameter, intended for receiving a locking nut. In an especially preferred embodiment the arm or plate has the form of a tension arm which at one end thereof is loosely hooked onto one side of the friction housing, spans this and on the diametrically opposite side is secured with adjustable retaining force. In a variant of the last-mentioned method, the tension arm can be replaced by a locking nut, which provides a mechanism essentially the same as the first-mentioned friction mechanism, but turned relative to the plates. As mentioned above, the invention also relates to an opening device for sliding out frames of parts as described above when opening them, and this is characterised by a block and a pivot pin; a long lever with spacing and release holes; a short lever, fixed to the long lever via holes in one end and fixed to a slide rod at the other end, the lever being intended for turning around the pin for movement of the frame 14 upon opening in order to turn the U-shaped mouldings, and a mounting which allows controlled movement of the short lever during turning. Additional features and advantages of the invention will be set forth in the description below and in the accompanying claims in connection with the attached figures wherein: Figure 1 is a cross-section through a possible embodiment of a window of the type comprised by the invention; Figure 1 a shows a friction moulding according to the invention; Figures lb and lc are cross-sections which indicate the location and position of the friction mouldings, and where Figure lb also shows an opening device; - Figures 2a to 2c show a possible embodiment of a swivel or pivot mounting; Figures 3a to 3f show another embodiment of a swivel or pivot mounting according to the invention with friction elements; Figures 5a to 5c show another embodiment of a swivel or pivot mounting with friction elements; - Figures 6a to 6c show yet another embodiment of a swivel or pivot mounting with friction elements; Figures 7a to 7g show a closing device as indicated in Figure lb with associated parts. In Figure 1 a double layer window is indicated by means of the reference numeral 18, held in a frame 19 which is mounted casing 20. Towards the weather-exposed side the window is equipped with fittings 22', 22", 22'" and 22"". The air tightness between the window frame and casing is secured by sealing elements, e.g., U-shaped sections 21 as indicated in la. These U-shaped sections are preferably fastened in pre-formed grooves by means of stripping 40 which is tacked or stapled in place. As indicated by the reference numeral 23, the casing and the frame may be equipped with sleeves and screws 24 for the optional moving of one or more of the sections 22 when turning the window. In this connection, reference is also made to the discussion of Figure lb. The window frame 18 in a preferred embodiment is divided into two parts 19 and 19', preferably placed against one another with tongues and grooves 38 to ensure lateral stability and fastened to one another by means of screws as indicated at 39. The window assembly as shown in Figure 1 is intended to be turned about an axis perpendicular to the paper plane and which lies in a plane in the centre of the "casing/frame cross-section". A rotation of 180° of the window 18 in the frame 19 whilst it is in the casing 20 is allowed due to a preferably relatively large space between the frame and casing, a space that is preferably at least 3.2 mm. As mentioned above, the air tightening takes place preferably by providing U-shaped sections 21, secured to the frame and/or casing and of a dimension such that they are in constant contact with the superjacent part. The turning may also be a pivoting so that the axis of rotation is horizontal, all the mouldings and the like then simply being moved correspondingly. Fastening the moulding to the frame and casing takes place with the aid of screws as indicated by 24. Figures lb and lc show a cross-section which indicates possible locations for the friction mouldings and also of a closing device 33 which will be described in more detail below with reference to Figure 7. When pivoting the window with pivot mountings as described below, the U-shaped mouldings arranged on each side of the window are preferably arranged as shown in Figures lb and lc, but it is conceivable that all U-shaped mouldings at the top and bottom are secured only to the frame. When turning with swivel mountings in the centre of the top and bottom, the U-strips are arranged in the casing at the side and the top, but preferably in the frame at the bottom. In Figure lb the reference numeral 36 indicates a fixed mounting plate in the window frame for moving the device 33 if the window is to be turned by swivelling or pivoting. In Figure lc the swivel or pivot suspension is indicated by 37. Figures 2a to c show a simple form of mountings which allow the pivoting or swivelling described above. In principle it is irrelevant which parts are fastened to the casing and which parts are fastened to the frame, although owing to the necessary thickness of material it is generally preferable that the larger and more bulky part with the pivot bolt should be attached to the casing as will be described below. A space has been cut out of the casing for the pivot bolt plate 6 and the pivot bolt 7, connected to the mounting plate 3 via adjusting screws 5. The plate 3 is fastened to the material by means of non-illustrated screws in holes 25 suitable therefor. The mounting is of course so positioned that the axis of rotation runs through the longitudinal axis of the pivot bolt 7. Above the plate 3 there is arranged in the superjacent material a mounting plate 2, secured to the material by means of non-illustrated screws in screws holes 26 arranged therefor. To mount the pivoting part in question, it is first held and then turned into position so that the pivot bolt plate 6 and the pivot bolt 7 are drawn towards the mounting plate 3 by means of the screw 5. This means that the bolt 7 moves from the position shown in Figure 2a to the position shown in Figure 2b, that is, into engagement with the superjacent hole 2 in the plate 1. It should not be necessary to point out that the axis of rotation which runs along the longitudinal axis of the bolt 7 in addition to running in a plane approximately in the centre of the depth of the casing, also in projection divides the casing opening into two identical, upper and lower or left and right parts as the case may be so as to allow an approximately symmetrical turning. When swivelling or pivoting parts of facades such as windows and/or doors or combinations thereof, it may be favourable preferably to be able to adjust the friction to counteract, for example, undesirable impacts, gusts of wind and the like. One embodiment exhibiting this is illustrated in Figures 3a to f. In principle, the device shown in Figures 3 functions in the same way as that shown in Figures 2. The mounting plate 6 is secured to the mounting plate 3 via adjusting screws 5 and a bolt 7 runs through a hole in the plate 3 and in a hole thereabove in the plate 1 , both the plate 3 and the plate 1 being secured to the frame and the casing respectively as described above. In the embodiment shown in Figure 3a there is arranged between the bolt 7 and the plate 6 a housing 9 as shown from above in Figure 3b, in longitudinal section in Figure 3c, in cross-section in Figure 3g and from below in Figure 3d. This housing is equipped with a groove 28 in which the middle of the plate 6 engages. When the plate 6 is drawn towards the plate 3 by means of the screws 5, a friction element 8 of discs as indicated by 10 in Figure 3e and 11 in Figure 3f, the first held in place by means of lugs 30 in engagement with grooves 31 in the housing 9, and the second held in place by means of a rectangular hole 32 in engagement with a rectangular lug 29, will be pressed towards one another via a spring, here shown as a disc spring 12. The device as shown in Figures 3 allow a stepless and problem-free tensioning of the friction element. In the embodiment shown in Figures 2 and Figures 3 the space between the screws 5 should be slightly greater than the width of the frame 19 so that the screws 5 can be manipulated when the pivoting or swivelling part is in a plane essentially perpendicular to the paper plane. However, it may be desirable to have quicker and simpler facilities for adjusting the tensioning and such an embodiment is shown in Figures 4. In Figure 4a the bolt 7 can be seen with a friction element 8 consisting of discs 10 and 11 and loaded by means of a spring 12. However, in the illustrated embodiment the bolt 7 is made in the form of a double screw with an upper threading 14 having a relatively large diameter and a lower threading 16 having a relatively small diameter and a square-cylindrical part 15 arranged therebetween. The head 7, that is, the pivot bolt, is intended for engagement in a suitable plate 1. An adjusting nut 13 is screwed onto the bolt, and more specifically on the threading 14. A disc spring 12 is arranged under the adjusting nut 13 and discs 10 and 11 of the previously described type are arranged in the friction element in Figure 4c. The whole unit is locked by a locking nut 17 which is screwed onto the threading 16. When the bolt 7 with friction element 8 is put in place a part of the nut 13 will be visible and capable of being gripped with a suitable tool in the gap between the casing and frame, which allows a rapid and immediate adjustment of the friction element in any position of the window. An alternative embodiment of a mounting having a friction element is indicated in Figure 5a. Figure 5 is a side view of the device according to Figure 5a and Figure 5c shows the same seen from above. Another alternative embodiment is shown in Figures 6a to 6b, the images corresponding to Figures 5a to 5c. However, Figure 6a shows the tensioning mechanism for the friction element in a slightly different embodiment, wherein the arm 6', 6" has been replaced by a retaining nut 17 and on the other side of the friction elements 8 there is arranged a nut 13. This device corresponds essentially to the embodiment shown in Figure 3 a but where the elements have been "turned". The embodiments which are shown in Figures 5a to 5c and 6a to 6c are distinguished by a simple assembly, the mountings can be assembled in milled-out grooves between the mouldings in the casing and when mounting the window this can then be pivoted into place after a 90° rotation of the mounting in the casing. As mentioned above, the invention also relates to a closing/opening device. This device is illustrated schematically in Figure lb, indicated by 33 and shown in greater detail in Figure 7 and Figures 7a to 7g. The reference numeral 34 is used to indicate a block for a guide pin 34', screwed in place in a suitable manner in the casing 20. Fastened to a fixed mounting 36 on the window frame there is mounted a slide rod 38, locked by means of a locking plate 37 (see the top of Figure 7f and Figure 7g). A sliding element 35' is bent around the slide rod 38 and clinched to an arm 35 having a sliding track with slightly enlarged track areas 38 and a release opening 37. The sliding pin 34' on the block 34 is inserted into the arm 35 via the hole 37. The pin 34'is slightly stepped as can be seen from Figures 7c and 7d. The collar area of 34' which has the smallest diameter corresponds to the smallest width of the groove in the arm 35. The next largest area of 34' corresponds to the diameter 38 in the enlargements in the groove in the arm 35. This permits locking in a closed or chosen airing position without there being any possibility of accessibility from the outside of the window. As mentioned, the arm is released from the block 34 via the hole 37. A manipulation of the arm a) when the window is closed will, because of the fastening to the slide rod 38, the connection of the arm 35 to the bent element 35' by clinching and with the pin 34' as a centre of rotation, result in a movement of the window so that the "direction" of the mouldings is turned and the window can be opened without difficulty. To release the sliding pin 34' in the groove in the arm 35, an embodiment is conceivable as shown in Figures 7c and 7e wherein the pin is spring-loaded in the block 34. A simplified embodiment is shown in Figure 7d wherein the pin 34' quite simply is unscrewed from a block in the form of an angle element. As mentioned previously, the slide rod 38 is locked between a fixed mounting plate 36 and a locking plate 37 as can be seen from Figures 7f and 7g. By means of the inventive idea, namely to turn a window, a door a combination thereof, parts of facades, partitions and the like exactly 180° so that the whole unit remains in place and in sealing engagement with the surrounding casing, and by means of the outlined types of hardware which permit this, it is for the first time possible to be able to utilise all the technical possibilities represented by different types of glazing in terms of light and heat reflection and transmission. Because cladding panels, for example, are capable of being turned in a simple manner, these can be used both decoratively and commercially, with the possibility of, for instance, colour variations, patterned facades and not least advertising, since all these features can be put in place with relative ease and by turning the panel, can also be easily removed.
