A connecting piece (21) is fixed at one end in the masonry by wing bolts (23,24). A pin (25) allows assembly of the connecting piece to the chassis (11). A locking screw (31) is housed in a threaded housing (27) on the connecting piece. The pin allows a relative movement between the connecting piece and the chassis when the locking screw is rotated in the housing. The locking screw has an increasing diameter ferrule (33). The housing in the connecting piece is located so that the ferrule is located facing a protuberance (17) on the chassis. The connecting piece is slightly curved and tensioned when the locking screw is rotated in the threaded housing.

Description

SETTING DEVICE FOR FIXING CHASSIS OF

WINDOWS AND / OR DOORS.

Subject of the invention.

  The present invention relates to an adjustable wedging device for positioning window and / or door frames.

  The device is particularly suitable for setting the chassis in all planes quickly and easily.

Technological background.

  Conventionally, for wedging window frames and / or doors, use of sealing tabs called tabs IIZ "because of their particular shape.

  Several examples of such tabs are described in the following documents: - The document WO87 / 01756 describes a device for fixing a plastic profile extruded from the chassis using a screw, this fixing device also comprising a device for screw locking. Although this device allows positioning adjustment, it is a limited solution to extruded profiles and is of relatively complex placement. In addition, this device is not suitable for double walls comprising either a void or an insulating material included between the masonry block and the exterior facing brick.

  - Document DE-A-3047902 describes a similar device suitable for wooden frames, in particular door frames. This device wedges the chassis using screws arranged angularly.

  Consequently, these different types of device are not suitable for all types of chassis (wood, aluminum, PVC, etc.). Similarly, the use of such sealing lugs in constructions comprising an interior block generally made of concrete and an exterior facing brick separated by a vacuum or by an insulator can prove to be particularly delicate.

Purpose of the invention.

  The present invention aims to provide a wedging device for fixing window frames and / or doors of any kind. More particularly, this device makes it possible to place both wooden, aluminum or PVC frames.

  A complementary object of the present invention is to allow placement of the wedging device in a simple and rapid manner, so as to allow a significant saving of time.

  Another additional object of the present invention aims to propose a device which can be arranged in all the planes (horizontal planes and vertical planes).

  Another object of the present invention is to propose a wedging device which can be arranged between an interior block and an exterior facing brick, even when the latter are separated by a large vacuum or by a space filled with an insulator.

  Finally, the present invention aims to propose a wedging device which makes it possible to avoid the use of polyurethane foam or wooden wedges.

  Other purposes and advantages will appear in the

description which follows.

  Characteristic elements of the invention.

  The wedging device for fixing window frames and / or doors according to the present invention consists of four main components and complementary elements allowing their fixing.

  These main components are as follows: - a part known as a chassis part intended to be fixed to the chassis by appropriate means; a so-called connecting piece which can be joined at one end in the masonry; - A pin which ensures the assembly of the connecting piece to the chassis piece and - a so-called adjusting screw preferably allowing to exert a deformation stress on the connecting piece.

  Various embodiments of the invention are possible.

  According to a first preferred embodiment of the invention, the part known as chassis part can be provided with a protuberance (boss) while the so-called connecting part is provided with a threaded housing.

  In this case, the clamping screw is also provided with a tip with increasing diameter. A constraining force is exerted in this case by the clamping screw, the tip with increasing diameter exerting a constraining force on the connection piece because it applies to the protuberance.

  When the clamping screw is introduced into the threaded housing of the connection piece, the increasing diameter nozzle is located at the height and opposite the protuberance of the chassis piece.

  The connecting pin allows relative movement of the connecting piece when the clamping screw undergoes a rotational movement in the corresponding threaded housing, because the increasing diameter of the end piece acts on the protuberance by causing tensioning.

  According to an alternative embodiment, it is possible to provide in the so-called chassis part, at its end opposite to that by which it is fixed to the chassis, a threaded housing so that the clamping screw acts directly on the said part connection.

  An identical effect can also be obtained by providing a threaded housing also in the connection piece.

  Advantageously, the connecting piece is slightly arched, even in the absence of stress, in order to ensure a "spring" effect.

  The materials chosen are of suitable quality for the intended use; in particular the elements exposed to humidity such as the connecting piece will preferably be made of galvanized steel.

Brief description of the drawings.

  The present invention will be better described with reference to the various appended figures in which: - Figure 1 represents a view in horizontal section of the elements constituting a wedging device according to a first embodiment of the present invention, - Figure 2 represents a view similar to that of FIG. 1, but according to a second embodiment of the invention, FIG. 3 represents a front view which makes it easier to understand for the installation of a chassis & using several wedging devices according to the present invention.

  Description of several preferred embodiments of the present invention.

  FIG. 1 represents in a conventional manner a bay which must receive a door or a window and which consists of a masonry element, in this case a block 1.

  Also quite generally, a facing brick 3 is provided and separated from the block 1 by a space for which the reference 5 has been used, this space being either empty or filled with an insulator.

  The frame of the window or door frame which has received the mark 7 must be mounted perfectly vertical.

  According to the state of the art, it is usual to use four sealing tabs arranged at the four corners of the chassis.

  According to the present invention, there are also four wedging devices at the four corners of the chassis, of which a single wedging device is shown more particularly in FIG. 1.

  This wedging device according to the invention, more commonly known as wedging tab, is constituted by a part 11 known as a chassis part fixed in a conventional manner to the frame 7 of the chassis, for example using screws 13 and 15.

  According to a first embodiment, the chassis part 11 has a protuberance 17 (boss) whose function will appear further on in the description.

  A connection piece bearing the mark 21 is suitably fixed at one end to the masonry 1, preferably using a screw 23 and a dowel 24.

  At the other end, the connection is ensured on the chassis part 11 using a pin 25.

  This connecting piece 21 further comprises a housing 27 provided with a thread which allows it to receive a clamping screw 31. This clamping screw 31 is provided at its end with a nozzle 33 of increasing diameter.

  The arrangement of the threaded housing 27 is provided in such a way that, when the clamping screw 31 is introduced therein, the end piece 33 with progressive diameter acts on the protuberance 17 by progressively wedging the frame or more particularly the frame 7 of this frame.

  Because the connecting piece 21 acts like a spring-effect blade, the frame frame 11 will in this case be held firmly in place and completely secured to the masonry 1.

  In another embodiment shown in Figure 2, reference marks identical to those of the previous figure were used for identical or similar elements.

  In this embodiment, the part 11, called the chassis part, does not have a protuberance 17 (boss). At its end opposite to that where the screws 13 and 15 are provided, a threaded housing 28 has been produced intended to receive a screw 32 which acts directly at its end on the connection piece 21. Advantageously, the frame piece 11, its end o is provided with the threaded housing 28, is slightly curved so that the screw acts at an appropriate angle on the connection piece 21.

  In this embodiment, the adjusting screw exerts a stressing effect deforming the connecting piece 21.

  However, it is also possible to provide a threaded bore also in the connection piece 21 in which case an identical or similar effect can be obtained without actually putting the connection piece under tension.

  FIG. 3 represents the method of fixing a complete chassis in a rack. The assembly process is characterized by the following stages: - fix four chassis parts 11 on the frames 7a and 7b of the chassis, preferably at the four corners of this chassis, and place this chassis in the rack; - check the side jack (measurement X - X in the figure) on the left and right; - move the connecting pieces 21 of the two upper clamping legs A and B to the wall, and screw the tightening screws 31 or 32 fully into the corresponding threaded housings 27 or 28; - place the lower frame 7c in line with the upper frame 7d and carry out the same operations for the two lower setting lugs C and D; - drill and place four dowels 24 in the masonry for each of the setting lugs A, B, C and D, screw each time a screw 23 for each of the four dowels 24; - screw or unscrew each of the clamping screws 31 so as to precisely adjust the frame and to position the frames vertically and the openings parallel to the gate.

  As we have seen from the succession of steps in the assembly process, this is a particularly rapid assembly of the wedging devices while avoiding the placement of different thicknesses of wooden blocks or the use polyurethane foam.

  By way of example, one can cite a time saving of ten to fifteen minutes by placing the chassis.

  In addition, this device, when placed, is discreet and can be easily made invisible after recapping.

  Advantageously, the wedging devices according to the present invention can be placed on any chassis, whether it is made of wood, aluminum or PVC; only the shape of the chassis parts 11 will change depending on the type of chassis.

  It should be noted that in the particular case of new constructions, that is to say constructions where there remains a void or a space filled with an insulator, the wedging device according to the present invention is particularly advantageous for fixing frames door or window.

  On the other hand, it can also be noted that in the case where the device according to the present invention is used, it is not necessary to have several wedging devices to effect lateral positioning.
