FRAME PROFILE

Abstract: The invention relates to a frame profile (1) that is sub­ stantially U-shaped and has at least one substantially U-shaped edge (5). In order to attach a frame profile (1) firmly and without causing damage to a finished surface of a wall edge (39, an edge end (27) located at an interval from the edge body (8) grips for anchoring on a wall edge (3).

Description: The invention relates to a frame profile as indicated in the preamble of claim 1. Such a frame profile is disclosed in NL-A-8500395. The invention has for its object to provide a frame profile that can be attached firmly and without causing damage to a finished surface of a wall edge. To this end the frame profile according to the invention is characterized as indicated in claim 1. Displacement of the frame profile in the direction away from the wall edge is counteracted to a great extent as a result of the anchoring action of the edge end. The frame profile does abut the side surface of the wall edge uniformly over its whole length due to a portion of the inner edge flange which lies against said wall side surface without penetrating therein. It is remarked that from EP-A-0140436 a frame profile is known, the edges of which are not U-shaped. The edges then come up against the wall face at a right angle thereto. When these edges are clamped towards the wall face, a firm clamping on the wall face is indeed realized, but the edge thereby penetrates into the outer layer, for example a plaster layer, of the wall, which can result in the plaster work coming loose locally. Visible damage occurs particularly when, following initial clamping into position, the frame profile is moved slightly in order then to be clamped into a definitive position. From AU-B-511102 a frame profile is disclosed having U-shaped edges, the edge ends thereof being directed to the side surfaces of the wall edge. These edge ends are not used as anchoring means and the U-shaped edges do not accomodate clamp members. Further the inner flange of the U-shaped edge does not have a portion abutting the side surface of the wall portion without penetration at a distance from said edge end. In preference the inner edge flange has a local deformation at the position of at least one clamp. The position of the clamp in lengthwise direction of the frame profile is then easy to determine and fix. The invention will be elucidated in the description following hereinafter with reference to a drawing. In the drawing in schematic form: Fig. 1 shows a side view of a frame profile according to the invention having incorporated therein a profile clamp according to the invention; Fig. 2 is a section along line II-II from fig. 1; Fig. 3 is a section along line III-III from fig. 2; Fig. 4 shows on a large scale the detail IV from fig. 2; and Fig. 5 shows two frame profiles in a transporting situation. The frame profile 1 according to the invention has a substantially U-shaped profile with a recess 2 for receiving a door or window. This frame profile 1 is fixed in position on a wall edge 3 by means of a profile clamp 4. Frame profile 1 has two substantially U-shaped edges 5. The inner flange 6 and a connecting piece 7 of an edge body 8 of a U-shaped edge 5 together form a substantially S-shaped profile piece 9. Profile clamp 4 comprises a first angular clamping member 11 of which a first leg 13 extends along the body 10 of frame profile 1 and a second leg 16 along the narrow frame flange 18 of frame profile 1 located by the recess 2. Profile clamp 4 further comprises a second angular clamping member 12 of which a first leg 15 extends along the body 10 and a second leg 17 extends along a wide frame flange 19 of frame profile 1. Profile clamp 4 further comprises a clamping screw 20 and support means 21 connecting both first legs 13 and 15 for mutual pivoting. The first clamping member 11 has a second leg 16 that is slightly shorter than the narrow frame flange 18 present by the recess 2 and which is considerably shorter than the second leg 17 of the second clamping member 12. The second leg 17 is slightly shorter than the recess-free, broad frame flange 19. The first clamping member 11 is substantially L-shaped, while the second clamping member 12 is substantially U-shaped. The second clamping member 12 namely supports via a short spacer piece 21 on the first leg 13 of the first clamping member 11. This spacer piece 21 forms together with the clamping screw 20 the fastening means with which the clamping members 11 and 12 are attached for pivoting to each other and with which the profile clamp 4 is tensioned for fixing the frame profile 1 firmly in position on wall edge 3. As fig. 3 shows, the inner flange 6 has two incisions 23 at the location of the profile clamp 4, while the edge piece 24 lying between is curved towards the frame flanges 18 and 19. This edge piece 24 grips in a cavity 25 of a channel-like profiled first member 11 and second clamping member 12. Side edges 26 of the clamping members 11, 12 grip adjacent to edge pieces 24 onto the inner flange 6 and during tensioning of profile clamp 4 press the edge end 27 slightly into the material of the wall edge 3, which results in the inner flange 6 gripping for anchoring on wall edge 3. Close to the visible portion 28 of wall edge 3 the frame profile 1 is rounded off with a bend 29 so that the lie of the profile edge 5 at that location does not result in damage. The edge end 27, which can cause some surface damage to wall edge 3, lies at an interval a from the edge body 8. The clamping screw 20 in the form of a recessed head screw is accessible using a sizeable socket head screwdriver via an opening 30 arranged in the body 10 and closable with a cap 31. The clamping members 11 and 12 which are profiled over virtually their whole length are manufactured from reinforced metal and are practically form-rigid. Because of the large pivot angle over which the clamping members 11 and 12 can move relative to each other, the profile flanges 18 and 19 can move over a considerable range relative to each other, which results in the frame profile according to the invention being suitable for bridging wall edges with a large thickness tolerance. Through the use of a large socket head screwdriver which can be inserted into a substantial recessed hole of the recessed head screw 20, it is easy to apply a large fixing force by hand, for example a clamping force of more than 100 kg. The point at which the ideal clamping force is reached is not difficult to judge. Fig. 5 shows how two frame profiles 1 together with their profile clamps 5 may be laid into each other and transported using a minimum transporting space.
