Description: A Frame / The present invention relates to a frame, particularly intended for fire-proof doors and pre erably made of steel profile, this frame, which is designed to be fitte in an opening, particularly a wall opening, having an abutment shoulder which is . adapted to a closing element such as a door or the like, and comprising as well at least one fixing arrangement which is designed to be fixed to at least one edge of the opening intended for the frame, and adapts thereto. The main object of the present invention is to make it possible . to fix such a frame for closing elements such as doors, gates and windows in ' an opening in the wall of a building, simply and accurately, without any special work having to be carried out on the opening. The said object is achieved with a frame according to the present invention which is primarily characterised in tha the said fixing arrangement comprises at least one adjust able fixing device which extends along the opening plane of the opening and bridges the distance between the frame and the edge of the opening, and which can be locked to the said edge of the opening so as to hold and support the said fixing device and the frame in the desired position in the opening. The invention is described in the following with referenc to the accompanying drawings, on which Figure 1 shows in cross-section a frame constructed according to the invention and used for a door, Figure 2 shows the frame and the door viewed from their planar side, Figure 3 shows in cross-section a frame which is fixed to a brick wall, Figure 4- shows an alternative design for the frame, Figure 5 shows in cross-section a frame which is fixed to a wall which is not solid, Figure 6 shows a fixing device appertaining to the frame, viewed from the side, Figure 7 is a plan view o the fixing device shown in Figure 6, Figure 8 shows in cross-section a frame constructed according to the invention with its associated covering strips, and Figure 9 shows in cross-section a fixing device which can be used for fixing the frame constructed according to the invention. In Figure 1 there is a door leaf designated with the numeral 1, or more specifically a fire-proof door leaf 1 which is supported pivotably by means of hinges 2 on one of its vertical edges on a frame 5 constructed according to the invention which is fixed to the edge 3 of an opening 3 in a wall 4-. A frame part 5C expediently suppor the said hinge 2 while another frame part 5 has a f OM - cavity 6 which preferably has an adjustable lock bolt guard 7 which is designed to accommodate a lock bolt 9 which is mounted in the door leaf 1 so that it can be displaced in a lock case 8. In the example shown in Figures 1, 3 and 5 the wall 4- to which the frame 5 is fixed is of the type which consists of plates 10 which are supported on battens 11, forming a hollow space 12 between the plates 10. The frame 5 is formed, for example, of three frame parts 5A, 5B and 5C which, together with a door sill 13, are preferably assembled together to orm a unit in manner which i ' s known per se, before they are inserted in the opening 3 in which it is desired they should be supported. However, it is also possible to assemble the various part together to form a frame* on site, where the opening 3 is located, if so desired. All the frame parts 5A, 5B, 5C, which are preferably 2 made of steel profile, with two frame side shanks 5 ~ and 5 respectively located at a mutual distance from 1 each other projecting from a central frame part 5 and suitably bent round at their respective free ends 5 and 5 , each have an abutment shoulder 3 which is adapted to the intended closing element 1 which it is desired to support thereon.- The frame 5 also comprises a number of fixing devices 14- appertaining to the fixing arrangement, of which at least one such fixing device 14- extends along the opening plane of the opening 3- In the embodiment shown on the drawings in Figure 2 the frame 5 is fixed to the wall 4- with the aid of three short fixing devices 14- in each vertical frame part 5A and 5C respectively, with one similar " fixing device 14- in the horizontal frame part 5B. Naturally, it would be entirely adequate to fix the frame 5 with a single fixing device. This fixing device would then preferably be made as an elongated device, in order to ensure that the same function is fulfilled as in the arrangement with a plurality of shorter fixing devices 14-, the function of which will now be explained in more detail. A fixing device 14- is formed of a part 14- in the form of a profile. The said fixing device 14- is formed of a flat part 14-A with two side shanks 14-3, 14 projecting out from the flat part 14-A at a mutual distance from each other. Along each of the side shanks 14-B, 14-C a guideway 15 extends from a widened guideway section 15A, sloping towards the flat part 14-A of the device 14- which forms what may be called an element of the fixing device. In the vicinity of the said widened guideway section 15A each of the shanks 14-3, 14-C is provided with a recess 16 or the like to form an entrance 153 through into the said guideway 5. The said fixing device 14- is designed to be mounted in the frame 5 by means of .projecting fixing elements 17 ? before it is introduced into the opening 3 in the wall 4-. The projecting fixing elements 17 may have the cross-section form shown in Figure 9 5 for example, like a boss 17 equipped with a hole 17A and having a flange shape 1?B, which is preferably fixed onto the insid 4 ~ c of the two bent ends 5 and 5^ respectively of the frame part when the frame 5 or the frame parts 5A _ 5c are delivered from the factory, as s ow in Figures 1 and 3, by means of rivet-like devices such as blind rivets 18 for example. The frame 5 is fixed in the opening 5 in the following way: .The adjustable fixing profile 14- is placed with its flat part 14-A turned away from the frame 5 so that an entrance passage 1 B on the two shanks 14-B, 14-C on ' the fixing device 14- comes directly in front of its respective pro- jecting boss 7 on the frame 5* so that the said bosses 17 can be introcLuced through the passage 15B into their respective guideway 15. Preferably, the respective fixing devices 14- are attached to the frame t>7 means of the pro ecting fixing elements 7 in such a way that when the fixing device 14- is displaced in the vertical directi of the frame 5 the said device 14- is moved in the directi away from the frame 5 and towards the side edges 3A of th opening due to the fact that the guideways 15 converge in the direction towards the contact section 14-A. When the respective fixing device 14- has been moved sufficiently, so that it rests with its contact section 14-A against the edge 3A of the opening 3 against the fixed battens 11, for.example, a hole 1 is made in the said fixed batten 1 and is preferably also tapped. Through a cut-out 20, preferably provided beforehand in the contact section 14-A a fixing element is inserted, for example, in the form of a screw element 21 equipped with a washer, which is screw tight in the tapped hole 19. This is made possible from the outside of the frame 5 v a mounting hole 22 in the frame » which may be closed off expediently with a plug In the event that the battens 11, etc. are too thin to have the frame 5 fixed to them, the batten 11 may be strengthened by means of a strengthening plate 24-, etc. The space between the frame 5 and the wall 4- is covered in preferably by means of an elastic fixing element such as a sealing substance 25, for example, as shown in Figure 1. The frame 5 or the various frame parts 5A - 5C are finally fixed when all the fixing devices 14- are.screwed firmly in the wall 4- in the manner described above. Figure 3 shows how a frame element 5 is fixed to a solid brick wall b means of a wood-screw 211 which is screw into a plug 26 which is inserted in an opening 27 in the wall 4 5 . Figure 4 shows an alternative version of a frame 5 fixed to a brick wall 4^. Figure 5 shows on a larger . scale the fixing of a frame 5 mounted-in a hollow wall 4, with a rubber profile element 28 inserted in ' the intermediate.space between the frame 5 and the wall 4. Screening strips 31, 32 which bridge the distance between the frame 5 and the wall 4 are attached, as shown in Figure 8, by using soring clips 29, 30 which preferably ~ 2 4 have a shape adapted to the respective shanks 5 , 5 and 5 5 , 5 5 of a frame 5. The hollow space located inside the frame 5 is preferably filled up with some kind of insulating material 33, such as rock wool, for example. The invention is not limited to the embodiment example shown on the drawings and described above, but can be modified within the framework of the following Patent Claims. For example, it is possible to arrange more pair of projecting fixing elements on each frame section, with a corresponding number of guideways on the respective fixing profile devices or, instead of fixing the project¬ ing fixing elements 17 to the frane 5, they may be fixed to the side shanks 143, 14C of a fixing device and the slanting guideways may be arranged instead on the frame 5 in which the fixing elements are then designed to be accomodated in a similar way to that described above.
