Device for installing a window or door frame in an opening in a wall

The invention relates to a device for mounting a window or door frame in a wall in an opening formed by a bracket to be placed between the wall and the frame, which is fixed in place by means of wedges or a wedge.

Doors and windows are usually fastened first with wedges, after which the frames are nailed or screwed to the wall. Because the distance between the frame and 10 parts of the adjacent building varies, this work can be time consuming, especially when wedges are flowing from pieces of wood material and pieces hanging on the construction site. Various assembly solutions have been presented in the past, and examples of these can be found in EP patent application 01 47 563 and in generally published DE patent applications 24 05 838 and 24 26 080. However, these previously known devices have the disadvantage that they consist of many parts and are thus expensive to manufacture. In addition, the installation time is long, as the devices require precise fitting work and several work steps in order for the solutions according to the proposals to achieve a sufficient holding force during the deformation and bending of the frame parts.

20 With regard to the prior art, reference is also made to DE-A-20 44 911, which discloses a fastening strip for mounting a door or window assembly in a wall opening. The end of the strip has holes that act to attach the strip to the frame portion. The strip according to the reference does not have teeth and does not have any device that would allow tightening if necessary. adjusting the clamping force after the door assembly 25 is installed in the wall opening. The reference shows a strip that must be attached to the edge of the door opening, after which the door assembly can be placed in the door opening.

In addition, with reference to the prior art, reference is made to GB-A-2 188 986, which discloses a spacer for use in fitting a spring-loaded window frame wall opening, the spacer being substantially U-shaped, with a fixing screw or the like inserted in the U-slot. The spacer according to the reference thus provides a suitable distance between the frame and the wall while the frame is screwed to the wall.

In addition, with regard to the prior art, reference is made to FI patent 86329, which discloses a device for mounting a window or door frame in an opening in a wall and a tool for use in connection with a device in which the frame is first centered in the opening with wedges or a specially designed device. next, an elongate metal plate is threaded between the frame and the opening, and then the metal plate is pressed together longitudinally by means of a tool, whereby the metal plate bends into a zigzag shape, whereby the teeth 5 in the metal plate secure the frame 5 in place. The disadvantage is that the fastening method in question does not allow the frame to be adjusted after fastening, it is difficult to dismantle the fastening and, in addition, a special tool is required for fastening. The centering device used in connection with the installation of the frame is cumbersome to use and, in addition, it is an expensive investment, and the price is further increased by the special tool required for fastening.

It is an object of the present invention to provide an apparatus for installing doors and windows in which the above drawbacks have been eliminated. The device is cheap to manufacture, for example, by stamping, and in addition, the device can be installed quickly without a special tool by means of a wedge or wedges.

The device according to the invention provides a decisive improvement over the above-mentioned drawbacks. To accomplish this, the device according to the invention is characterized in that the bracket consists of a thin plate with at least two rows of teeth at an angle of 180 ° to each other and that the wedge or wedges 20 have pressed the teeth against both the wall and the frame.

The most important advantages of the fastening device according to the invention are that the fastening of the frame takes place without holes to be drilled through the frame. In addition, the frame can be adjusted even after mounting by moving the wedges. The fastening method is advantageous when using ready-made wedges made of chipboard, which are available from the supplier of the fastening device. It is easy to cut off the excess from the wedges made of chipboard. The fastening method is fast, because the wedges used for fastening also center the frame. No separate equipment or tools are required. Only a hammer on every builder is needed. The fastening performed by the fastening device 30 is firm and secure. In addition, it has a wide operating range, as the adjustment is done by increasing the number of wedges. If necessary, the attachment can be quickly dismantled without visible damage. When attaching the frame, there is no need to unpack the window or door, but the packaging plastics can be left in place for protection during construction. The wall-side part of the fastening device can be fastened to the metal frame post 35, e.g. with screws, POP rivets or the like. Otherwise, the above fastening methods can be used in special cases.

The invention will now be described in detail with reference to the accompanying drawing, in which Figure 1 shows a fastening device perpendicular to the side; Fig. 2 shows a perpendicular top view of the fastening device; Fig. 3 shows the fastening device seen from a perpendicular end; Fig. 4 shows the fastening device in the fastening situation of the frame as seen in the direction of the frame; and Figure 5 shows some tooth shapes of the fastening device.

10

Figure 1 shows the shape of the fastener 1. The fastener 1 has two rows of teeth 2, one of which is intended to adhere to the frame and the other to the edge of the wall opening. In addition, the fastener 1 has tongues 3 which guide the wedge or wedges to the correct position of the fastener. The fastener 1 can be made of, for example, a thin metal plate by means of a plate work-15 workstation or the like.

Figure 2 shows the auxiliary holes 4, which may be several if necessary. They are intended for fastening to difficult fastening objects, such as a concrete surface, in which case the row of teeth on the concrete surface side is straightened with a hammer and the fastening is performed by means of a concrete crack and a screw.

Figure 3 shows a preferred shape of the tooth 2.

Figure 4 shows the wall 7, the frame 8 and between them there is a fastener 25 1 in the fastening situation. The wedges 6 have pressed the teeth 2 into the wall 7 and the frame 8. The position of any auxiliary screw 5 is shown in the figure.

Figure 5 shows various preferred shapes of tooth 2. The shape, number and size of the tooth may vary when using different fastening materials, and in addition, the shape of the teeth 2 of the fastener 30 1 may vary depending on the manufacturing technique.

Fastener 1 works as follows. First, the frame is placed in the opening in the right place using wedges. The fasteners 1 are then inserted between the frame and the wall, conveying them, e.g. by means of the tip part of the wedge 6. When the fastener is in the right place, the teeth 2 are immersed in the wood 2 by means of one or more wedges 6. The wedges 6 remain well in place by means of a sharp corner 3a in the tongue 3. Another way is to fasten the fasteners 1 in place by hitting the teeth 2 against either the wall or the frame. The frame is then lifted into place and aligned with wedges. Next, the wedges 6 are inserted into the fasteners 1 and the teeth 2 are closed, after which the alignment wedges can be removed if desired and the frame remains firmly in place. If the wedge in the fastener remains outside the surface of the frame, it is easy to cut it off by breaking, because the wedge is made of chipboard. Post-installation adjustment is possible by reversing or hitting the wedges deeper, because even if the wedges are reversed, the teeth do not rise out of the wood by themselves. If the frame is to be removed, the wedges must first be removed, after which the teeth can be lifted out of the wood, eg with a screwdriver.

It will be apparent to one skilled in the art that the invention is not limited to the example set forth above, but may vary within the scope of the claims. For example, the width / length ratio of the fastener can be varied, the dimensions can vary and there can be several rows of teeth.
