Description

The invention relates to a hinge fitting for a door, window or the like, comprising a fixed part intended to be fixed on the frame of said door or window and a part mobile made integral with the opening and provided with at least one bushing crossed by a hinge pin engaged in at least a yoke associated with the fixed part, blocking means ensuring the immobilization in axial translation of this axis.

The present invention will find its application in the field of the building hardware and concerns, more in particular, the hinge fittings.

A number of fittings are already known articulation corresponding to the above description and which distinguish by a fixed part which we just relate on the frame of a door, window or the like, while the opening receives the movable part of this fitting of articulation, knowing that their cooperation takes place by means an axis of articulation.

More particularly, this mobile part, also called blade, comprises at least one socket through which the axis passes of the aforementioned articulation which is, moreover, engaged and maintained in the bore of at least one fork of the fixed part.

For example, the sleeve of the movable part can be located above and in the axial extension of a single yoke, also in the form of a socket, of the fixed part, just like this can include two yokes coming from both sides and on the other side of the sleeve of the movable part so as to receive the ends of the hinge pin.

According to another embodiment, the mobile part can be equipped with several sockets located in the axial extension one from the other and framed with screeds of the fixed part, the one and the other being crossed by the axis of articulation.

In the vast majority of cases, this axis of articulation, when it contributes to the pivoting of a door leaf or window around a vertical axis, is engaged from the top in the fixed part and the mobile part of the articulation fitting, to ensure their connection. Stop means provided at the level of this articulation axis, even at the level of the fixed part, prevent it from being released unexpectedly by simple gravity. During assembly, such stop means also allow the user to ensure that this axis of articulation is completely engaged in the hinge fitting.

Having said this, it should be noted that there are also situations in which this axis cannot be engaged or withdrawn from above, for example in the case where the fitting articulation, ensuring pivoting around a vertical axis an opening, is located very close to the delimiting lintel, in the upper part, the opening of a door, window or similar. Also, this articulation axis cannot be engaged to guarantee the cooperation of the mobile part with the part fixed, only from the bottom, so it is necessary to equip the means locking fitting preventing this axis of articulation is not released by simple gravity, means which can be defined by a simple stop element as this has been explained above.

In this regard, it is quite usual to machine at this axis articulation, grooves intended to cooperate with clips blocking equipping the fork (s) of the fixed part.

If such locking clips are able to secure with efficiency the function assigned to them makes it difficult ensure through them that when mounting opening it from a door or window on its sleeping frame, so when it comes to making the movable part of the hinge fitting with the fixed part, that this axis joint was brought into a fully engaged position. However, if this is not the case, it is likely to unexpectedly release, and cause the opening of the opening relative to its sleeping frame.

There are also other known solutions which either prove to be restrictive from a design point of view, as the case may be even hinge fittings or even operations to lead to bring the moving part in cooperation with the part fixed and make active the axial blocking of the hinge pin.

It is also known to house around the edge of a screed a fixed part, or even a socket of the mobile part, a hole for the passage of a locking screw or pin coming to cooperate, therefore, with the hinge pin to prevent it from being released by simple gravity. Obviously such locking screws or pins are parts that the operator or user can lose during assembly and disassembly of the door leaf, window or similar. Furthermore, such parts are incapable, alone, to warn this operator or user that the hinge pin has or has not been properly inserted into the prior.

Document EP-0 0 628 688 discloses a fitting articulation whose fixed part is defined by a plate surmounted by three screeds between which are inserted sockets associated with a movable part, these yokes and these sockets being defined capable of receiving a hinge pin. This is immobilized axially by means of locking means associated with the central yoke of the part fixed. In fact, these blocking means consist of a button lock rotatably mounted in a housing provided for this effect at the level of this central yoke. This button locking is, therefore, likely to occupy a first unlocked position and a second locked position in which it cooperates, by means of locking nipples suitable, with a peripheral groove formed at the axis of articulation.

It will be noted, more particularly, the absence in such a design of indexing means for indexing the position locked and the unlocked position of this button. Only one visual identification allows a knowledgeable operator with a practical constant in the use of this type of fittings of articulation, to determine, according to the position of this locking button, if the articulation axis is correct locked in axial translation.

The object of the present invention is therefore to offer articulation fittings equipped with means of Axial locking of the hinge pin which are locked and with manual unlocking and which cannot be made active only if the axis of articulation has been previously perfectly positioned in the screed (s) of the fixed part, as well as the or the sleeves of the moving part.

The design of these blocking means is intended, however, simple and easy to handle.

To this end, the invention relates to a hinge fitting for door, window or the like, having a fixed part intended to be fixed to the frame of said door or window and a movable part made integral with the opening and provided at least one socket crossed by a hinge pin engaged in at least one yoke associated with the fixed part, this articulation fitting further comprising locking means in axial translation of said articulation axis, characterized by the fact that said blocking means are locked and manual unlocking and are defined by an element forming bolt secured to the fixed part or to the hinge pin and provided capable of cooperating, in the locked position, with a keeper part, respectively, of the hinge pin or of the fixed part, said latch element comprising, again, indexing means for indexing its position locked and its position unlocked.

The invention will be better understood on reading the following description relating to an exemplary embodiment illustrated in the attached drawing.

• Figure 1 is a schematic representation in longitudinal section of a hinge fitting according to the invention;
• Figure 2 is a schematic bottom view of Figure 1, the latch member of the axial translation locking means of the hinge pin being in the unlocked position;
• Figure 3 is a view similar to Figure 2, the lock member being here shown in the locked position.

As shown in the attached drawing and more particularly in Figure 1, the invention relates to a hinge fitting for door, window or the like, ensuring, therefore, the pivoting connection between the opening of this door or window with its sleeping frame.

Thus, this articulation fitting 1 comprises a fixed part 2 intended to be attached to this sleeping frame and with which comes to cooperate a movable part 3 made integral with the opening, this via a hinge pin 4.

More precisely, this axis of articulation 4 comes pass through the bore of at least one socket 5 of the movable part 3 and is engaged in at least one yoke 6, 7 that comprises the fixed part 2. In this regard, it is illustrated in Figure 1 a fixed part 2 comprising two yokes 6, 7 having a bore 8, 9 for receiving the ends 10, 11 of the axis articulation 4, knowing that between these yokes 6, 7 extends, axially, the socket 5.

As already explained in the section introductory, the present invention is in no way limited to a hinge fitting conforming to this single mode of production. In particular and by way of example, the mobile part 3 can be provided with several sockets, systematically framed by screeds in the fixed part, all of these bushings and yokes being crossed by the axis hinge 4.

In fact, the invention aims to respond to a problem that one meets, more particularly, in the case where, for reasons for size, articulation axis 4, defining substantially a vertical pivot axis of an opening by relative to a sleeping frame, must be inserted from below in the socket (s) 5 and the fork (s) 6, 7, respectively of the mobile part 3 and the mobile part 2 of the articulation fitting 1. In these conditions it is advisable to make sure during assembly that this hinge pin 4 is fully engaged to guarantee a perfect connection between this moving part 3 and the fixed part 2 and then prevent it does not emerge from the latter by gravity or friction, especially when handling the door, window or similar.

For this purpose and according to the invention the hinge fitting 1 comprises locking means 12 in axial translation of the axis hinge 4 which are locking and unlocking manual. They are defined, advantageously, by an element forming lock 13 made integral with the axis of articulation 4 and which is provided capable of cooperating, in locking position, with a striker portion 14, respectively, the hinge pin 4 or the fixed part 2.

However, it must be considered within the reach of the skilled person. overturn this construction.

Thus, the latch member 13 is in the form of a stirrup 15 mounted to slide, perpendicular to this axis of articulation 4 on one end 11 of it.

More precisely, at this end 11 the articulation axis 4 has a peripheral groove 16 defining, at the bottom of groove, a section 17 adjusted to the width 18 of a cutout 19 that includes the stirrup 15 and allowing the latter to move between a locked position 20 corresponding to the Figure 2 and an unlocked position 21, as visible in figure 3.

Preferably, these locked positions 20 and unlocked 21 of the latch element 13 are indexed relative to the axis of articulation 15 by means 22 appropriate.

According to a preferred embodiment, such means indexing 22 are defined, at the cutout 19 of the caliper 15, between the locking position 20 and the position unlocking 21, by a throttle 23 of width lower than section 17 of said hinge pin 4 at the bottom of groove 16. Note that the cutout 19 opens out into periphery of the stirrup 15 so as to define two branches 24, 25 having, between them, a certain elasticity allowing, specifically, the crossing by the axis 4 of the constriction 23.

Advantageously, the cutout 19 opens out through a second throttle 23A authorizing, of course, the mounting of this caliper 15, therefore of the element forming a lock on the axis articulation 4 by making them integral.

It will be observed that this stirrup 15 comprises, again so advantageous, obviously 26 in the axial extension of said cutout 19 for receiving a tool, such as a screwdriver, thus allowing to push back this element forming lock in active locking position 20 or in position unlocked 21.

Finally, the stirrup 15 which defines this lock-forming element 13, is completed by a locking tab 27 plus specially designed to cooperate with the striker portion 14 formed at the level of the fixed part 2. Obviously, this part forming a keeper 14 is preferably located in the extension of clevis 7, on the accessible side of the fixed part 2, or on the engagement side of the hinge pin 4.

According to a preferred embodiment, this part forming keeper 14 is in the form of a notch 28 adjusted for receiving the tongue 27 and formed in a sole 29 of the fixed part 2 from which extend the yoke (s) 6, 7.

Advantageously, the locking tab 27 of the element forming latch 13 is provided with positioning means 30 provided able to cooperate with positioning means complementary 31 at the level of the striker part 14. In the extent that the latch member 13 is likely to pivot around the hinge pin 4, it is advisable to ensure its correct angular positioning when lock command so that it can cooperate with efficiency with this striker part 14. In this dispute such positioning means 30 also make it possible to keep stationary in rotation relative to this part forming a keeper 14 the element forming a lock 13, after locking.

According to one embodiment, the positioning means are have the form of a lug 30, extending at the end of the tongue 27, perpendicular to the plane of the latter and in a direction opposite to the articulation axis 4. Thus, this lug 30, in the locking position of the element forming a lock 13, engages in a cutout 31 in the part forming a keeper 14. This cutout 31, which communicates with the notch 28, corresponding to said positioning means complementary.

Thus, when mounting an opening on the sleeping frame of a door, window or the like, consisting in bringing the movable part 3 of a hinge fitting 1 in cooperation with the part fixed 2, the hinge pin is inserted 4 in the yoke (s) 6, 7 and socket 5, respectively of this fixed part 2 and the mobile part 3.

Once this step has been completed, the operator activates the means of blocking 12. However, this can only be carried out if the element forming a lock 13 is positioned in front of the part forming keeper 14. If this is not the case, this operator knows, immediately, that the hinge pin 4 has not been suitably inserted at the hinge fitting 1.

It should be noted that, as in the past, the means of locking in axial translation 12 of the hinge pin 4 can complement other means of immobilization intended, in particular, to facilitate the installation of an opening on a sleeping frame. Indeed, during this installation, it can be practical to have axial locking means that activate automatically and avoid the fallout of this axis of articulation 4 from the yoke (s) 6, 7 and socket 5, the time for the operator to bring the latch element 13 into the position of lock 20.

Thus and according to an exemplary embodiment, in the bore 8, 9 yokes 6, 7 can emerge, at least partially, a clip of blocking 32 capable of being elastically erased when the introduction of the articulation axis 4 for, when the latter is in the fully engaged position, being pushed back, automatically, in a peripheral groove 33, 34 formed, in correspondence, at the level of this axis of articulation 4.

The advantages resulting from the present invention consist of a considerable gain in security, insofar as it allows to warn the user of the correct positioning of the articulation axis at the level of the fitting and to prevent any risk of disengagement unexpected. The invention turns out, again, of simple design and, therefore, easy industrialization.
