Description

The present invention relates to a hinge fitting for a door leaf, residential shutter or piece of furniture or the like, of the type comprising first and second elements mounted respectively on a fixed support forming a frame and said leaf, one of the elements comprising a pivot, while the other element has a crapaudine around the pivot, the pivot and the crapaudine being fixed to the frame or to the leaf by means of a hinge comprising-- fixing holes intended to receive elements of fixing, and an adjustment member intended to adjust the positioning and / or the inclination of said fitting and of the door or flap during its installation, at least two of the fixing holes having an oblong shape, extending substantially in the extension of the common longitudinal axis of said holes or optionally along parallel axes.

By US patent US-A-2 611 921, there is known a hinge pivoting on plug hinges and one of the hinges consisting of a rectangular metal blade has a rectangular hole. Said blade can slide along a groove made in a fixing plate fixed on a fixed support or on a leaf using screws.

An adjustment member consisting of an octagonal piece comprising an eccentric fixing hole is engaged in the above-mentioned rectangular hole, in a determined position, so as to adjust the position of the hinge relative to the fixing plate.

Once in place, the octagonal piece is fixed to the support or to the aforementioned leaf, also using a screw. The assembly constituted by the fixing plate, the metal blade forming the hinge and the octagonal part, is covered with a covering plate intended to hold the octagonal part in place and to hide it by a united surface, forming a third thickness.

The major drawback of this known fitting lies in the difficulty that installers experience in adjusting the positioning of said fitting when installing a shutter or a door. In addition, it is impossible to correct the subsequent play of a leaf, without completely dismantling said fitting. Finally, this known fitting comprises numerous parts of complex shapes which increase its manufacturing cost.

German patent application DE-A - 2635 237 relates to a hinge for furniture, a first hinge of which is fixed to the frame of the furniture with the aid of fixing elements and an adjustable sliding plate in the direction of the hinge pivot axis and a second hinge rigidly fixed to the door leaf. A setting member comprising an eccentric cam collaborates in the lateral movement of the adjustment plate.

The major drawback of this device lies in the fact that the adjustment can only be carried out in one direction and under the effect of gravity. Adjustment in a second direction, for example perpendicular to the first direction, is impossible because the hole in which the cam is positioned is rectangular. The cam only works on one lip of the hole.

In addition, the adjusting member does not contribute to fixing the hinge.

British patent GB-A-12,235 describes a fitting for a heavy door for a cold room. A first hinge of the fitting is rigidly fixed to the frame of the door. The hinge intended for the door leaf has horizontal oblong holes lined on their edge with toothed grooves. When the door is put in place, a threaded rod cooperating with a toothed washer facilitates precise mounting of the door so as to avoid gaps and loss of frigories.

This known device does not, however, include any control member for bringing the door into the ideal position. This adjustment can only be made in one direction.

The problem relating to the fitting of a shutter or door fitting results from the difficulty encountered by the installers in drilling fixing holes in the masonry in the correct position, despite the use of a template.

Indeed, it is very difficult to obtain holes in the walls at precise locations, possibly perfectly aligned, due to the fact that the force of the drilling tool used follows the path of least resistance in composite materials of masonry.

This lack of precision during drilling has the disadvantage of incorrectly fitting the leaves. The fault may be such that the closing of the leaf (s) is possibly prevented.

American patent US-A-2 885 722 suggests using a hinge comprising two hinges as the door leaf hinge. In the first hinge are provided first oblong fixing holes intended to receive screws.

Two of the holes extend in line with each other. The second hinge comprises a second hole extending in a direction perpendicular to that of the aforementioned first holes.

An adjustment member consisting of a toothed washer at its periphery is pivotally fixed using a fixing element. It allows the positioning and / or inclination of the fitting and therefore that of the door or shutter to be adjusted in steps.

The drawback of this known system lies in the fact that the adjusting member does not participate in the fixing of the hinge and that the adjustment can only be carried out by discrete value corresponding to the distance separating two teeth.

The object of the present invention is to eliminate the drawbacks described above. It offers a fitting of the type described in US-A - 2885722 forming a hinge for a door leaf. or residential shutter, furniture door or the like, of the type comprising first and second elements mounted respectively on a fixed support forming and said leaf by means of a hinge comprising first fixing holes of oblong shape, intended for receive fasteners, extending substantially in or parallel to the extension of the common longitudinal axis of said holes or possibly along parallel axes, while a second hole extends in a direction perpendicular to those of the first holes aforementioned and a control member consisting of a gripping head, pivotally fixed by a fixing element and integral with a cam engaged in the aforesaid second hole and intended to adjust the positioning and / or the inclination of said fitting and of the door or flap during installation, when the control member is actuated.

According to a feature of the invention, a hinge has three fixing holes of oblong shape, the intermediate hole having a longitudinal axis perpendicular to the common longitudinal axis of each of the two end holes.

The adjusting member advantageously comprises a fixing element serving at the same time as a fixing member.

The invention also relates to a method for adjusting the positioning and / or the inclination of each of the elements of said fitting.

This method is essentially characterized in that one introduces into any one of the oblong holes extending in the hinge in a direction perpendicular to that of the first aforesaid holes, a control member consisting of a fixed element and d 'A hexagon head controlling a cam pivotally mounted around the above fixed element, which is actuated in rotation by a maximum of half a turn using a key.

In these different figures, the same reference notations designate identical or analogous elements.

Figure 1 shows a type of fitting, designated as a whole by the reference notation 1 and intended to ensure the pivoting around a vertical axis of a leaf 2 which can be a door or a shutter of which only the upper part has been represented.

These fittings comprise a first element mounted on the leaf 2 and forming a horizontal hinge 3, and a second element 4 forming a hinge fixed on a fixed support forming the frame of the leaf 2.

These first and second elements are fixed respectively to the leaf 2 and to the frame by means of fixing elements, not shown, such as screws, lag screws, burglar-proof bolts or the like, introduced into corresponding holes made in each of these elements which thus articulate with each other in order to ensure the pivoting of the leaf 2 around a vertical axis L L '.

Each horizontal hinge 3, as illustrated in FIGS. 3 and 4, is constituted by a metal tab of substantially rectangular shape and crossed by holes 5, 6 for the passage of fastening elements 7 such as screws.

The holes 5, 6 advantageously have an oblong shape and extend in the extension of one another. In the example considered, these oblong holes 5, 6 are in longitudinal alignment on the hinge 3 and are located on the axis of symmetry of this tab.

One of the ends of the hinge 3 ends in a rounded loop substantially closing in on itself so as to define a substantially cylindrical open passage and whose axis is perpendicular to the axis of symmetry of the fixing lug. This rotary member 8, also called the node of the horizontal hinge, acts as a basket as shown in FIG. 4.

The element 4 forming a hinge is illustrated in FIG. 5. It has substantially the shape of a T, the head of which is arranged vertically. The head of the T of this element 4 acts as a fixing lug for this element on the frame and has fixing holes 9, 10 of oblong shape intended to accommodate fixing elements not shown which may be screws, lag screws, anti bolts -breaking or the like. As in the case of the horizontal hinge, these holes 9 and 10 are aligned longitudinally and are located in the axis of symmetry of the elongated fixing lug and of substantially rectangular shape.

The horizontal leg 11 of the T-shaped part of the hinge element 4 comprises at its end a pivot axis or journal 12 disposed perpendicularly to the leg of the T and integral therewith.

It will be understood from the above, that the articulation between the horizontal hinge 3 and the element 4 is produced by the rotation of the horizontal hinge around the pin 12 thus passing through the open passage of the lug 8 and extending in the axis of the joint.

The pivot 12 can also be removably mounted to the element 4 forming a hinge, so as to be able to transform each hinge into a hinge and vice versa.

Such a pivot is shown in FIGS. 6 and 7 and comprises an elongated hollow cylindrical upper part 13 for pivoting around the latter of the corresponding hinge, an elongated cylindrical lower part 14 being able to be inserted into a corresponding opening at the end of the hinge, and an annular part 15 for supporting the pivot 12 on the upper edge of the clamp.

The lower part 14 has ribs 16 extending along this part 14 and regularly spaced around it. By way of example, these ribs 16 are four in number and allow correct positioning of the pivot 12 in its corresponding opening 8.

According to the invention, each fixing lug of each element 3, 4 of the fitting comprises a second hole 17 forming an adjustment light, preferably situated between two holes 5, 6 and 9, 10 intended to each receive a fixing element 7, as shown in FIG. 5. The longitudinal axis of this possible oblong lumen 17 is perpendicular to the axis of symmetry of the fixing lug and the geometric center of this lumen is in longitudinal alignment with the geometric centers of the oblong holes 5 , 6 and 9, 10.

Of course, the shape and arrangement of this oblong light 17 are also found on the horizontal hinge of Figure 3 and is shown in solid lines.

Furthermore, with each fixing lug of each fitting element is associated a control member 18 which, in the present case, and for the sake of simplification, is shown only in association with the horizontal hinge of FIG. 3.

As shown in Figures 8 and 9, the control member 18 comprises a head portion 19 under which is integrally attached a cylindrical portion 20 forming a cam. As it is clear from these figures, the longitudinal axis of the cylindrical part 20 is eccentric relative to the central axis of the head 19 of the control member 18.

In addition, a bore 21 coaxial with the axis of the head 19 crosses on either side the control member so as to allow the passage of a fastening element 7 of the control member 18 on the leaf or the dormant. A counterbore 22 is produced in the upper part of the head 19 coaxially with the bore 21 to allow passage of the head of the fixing element 7.

The external diameter of the cylindrical part 20 of the control member can be identical to the diameter of the passages defined at each of the opposite ends of each oblong hole. It is thus understood that the control member 18 can be mounted on each fitting element by inserting the cylindrical part 20 in each adjustment lumen 17, the head 19 of the member 18 coming to bear on the fixing lug of each element fittings by means of a circular bearing surface 23 serving as a connection surface between the head and the cylindrical part 20 forming a cam.

The fixing element 7 of the control member 18 serves as a fulcrum or pivot point for the movement of the cam 20.

As shown in FIG. 4, the lower end of the cylindrical part 20 is flush with the bearing surface of the hinge 3 on the leaf 2 when the control member 18 is mounted on the support tab.

It is therefore understood from the above that the holes 5, 6 and 9, 10 above and the slot 17 of oblong shape defined in each element of the fittings allow an adjustment of the position of each of these elements by a relative displacement between these oblong bores and their securing screws 7, this relative displacement being obtained by acting on the control member 18.

The positioning of each fitting element is carried out as follows.

Each fitting element is mounted on its appropriate support (casement or frame) using the fixing screws 7 passing respectively through the oblong holes 5, 6 and 9, 10 and in holes drilled respectively in the leaf and the frame using a template not shown. The screws 7 are not fully tightened.

- Then, each control member 18 is introduced into the oblong adjustment light 17. This adjustment member 18 is held by the screw 7 which is not fully tightened and serving as a pivot for the displacement of the cylindrical part 20 forming a cam.

The head 19 of the control member 18 having a hexagonal shape, it is therefore possible, using a key 24, to rotate this member 18 which, by means of the cylindrical part 20 forming cam acting on the longitudinal edges of the adjustment light, pushes the fitting element longitudinally on the screws 7 which thus serve initially as a guide for this fitting element.

When the position of the leaf relative to the fitting is correct, as illustrated in FIG. 2, it then suffices to definitively block the adjustment, to definitively tighten each screw 7 to firmly hold the member 18 and then to definitively block the screws in the oblong holes 5, 6 and 9, 10.

Thus the adjusting member 18 makes it possible to adjust the positioning of the leaf relative to the frame, both in a horizontal and vertical direction in order to compensate for any misalignment caused by a compaction of the building or due to imprecision in drilling the fixing holes when installing the shutter or door.

The adjustment system according to the invention also allows subsequent adjustment of the position of the leaf if the need arises, for example as a result of the work of the masonry or the wood of the leaf over time. Of course, this possibility of subsequent adjustment will be made by slightly loosening the fixing screws inserted in the holes 5, 6 and 9, 10, by loosening the screw 7 of the control member 18 and by rotating using a key 24 suitable for the head 19 of this control member 18 for the thrust movement of the fitting element.

Other modifications can be made to the adjustment system of each fitting element without departing from the scope of the present invention.

For example, the holes 5, 6 instead of being made along the longitudinal axis of the element 3 of fitting 1 can be made along a vertical axis of this element, while the adjustment light 17 will be made along the longitudinal axis of the fitting. It is therefore possible to combine this type of fitting element with another fitting element having holes made along the longitudinal axis of the fitting and an adjustment light perpendicular to this axis, the combination of these two fitting elements allowing also their displacement relative to each other in a horizontal direction and a vertical direction.

In addition, the adjustment lumen into which the cam portion 20 of the control member 18 is inserted may also have a substantially oval shape, the diameter of the cam corresponding to the smallest diameter of this oval bore.

The adjustment system according to the invention can also be applied to the types of fittings comprising respectively a square hinge (FIG. 10), a hinge for the connection of two leaves of a double flap (FIG. 11), a vertical folded hinge (figure 12) and a horizontal hinge (figure 13).
