Description

Quick assembly hinge, and assembly comprising such a hinge and a fixed frame and/or a sash.

This presentation relates to a hinge or equivalent.

By “hinge or equivalent” is meant any type of hinge, hinge, pin, hinge, etc.

Various techniques are known for mounting a hinge both on a fixed frame and on a sash arranged adjacent to the fixed frame in order to allow the opening and closing of the sash relative to the fixed frame.

However, these techniques are often complicated and require a relatively long assembly time.

It would therefore be desirable to have a new hinge mounting technique or equivalent offering a relatively reduced mounting time compared to known techniques.

To this end, the present invention relates to a hinge or equivalent comprising a first wing having at least one knuckle, a second wing having at least one knuckle, and a pin extending in an axial direction, the first wing and the second wing being configured to pivot relative to each other around the axial direction, the first wing and/or the second wing being provided with mounting means configured to mount said wing on a frame or an opening, the mounting means comprising at least one stud extending along a length direction and comprising a head and a body, the head being arranged opposite said wing with respect to the body along the length direction, the head having a width greater than one body width, the body width increasing progressively along the length direction from the wing to the head.

The presence of at least one such stud on one of the two wings, or even on both wings, makes it possible to easily and therefore quickly mount the wing (or wings) on the facing wall (frame or opening) by inserting stud into a corresponding mounting hole in that wall.

According to other possible characteristics:
- Said at least one stud has a circular cross-section and the body has a generally frustoconical shape;
- the means for mounting the first wing and/or the second wing only comprise said at least one stud;
- the hinge or equivalent comprises locking means configured to lock the assembly of the first wing and/or of the second wing with the frame or the opening;
- the locking means comprise at least one through hole configured to receive a rod, a screw or a rivet;
- the first wing and/or the second wing comprise said at least one through-hole;
- Said at least one stud is a drilled rivet or a semi-drilled rivet.

According to another object, the present invention relates to an assembly comprising a hinge or equivalent as briefly explained above and a fixed frame and/or a sash, the fixed frame and/or the sash comprising as many mounting holes as the first wing and/or the second wing comprises studs, respectively, each mounting hole having the shape of a buttonhole.

The installation of the mounting hole(s) in the wall (frame or sash) is particularly simple and quick to make, which does not add any complexity to the assembly of the hinge.

According to other possible characteristics:
- when the hinge or equivalent comprises locking means configured to lock the assembly of the first wing and/or of the second wing with the frame or the opening, the buttonhole has a narrow portion and a widened portion with respect to the portion narrow, the locking means comprising at least one blocker configured to engage in the widened portion and block the stud in the narrow portion;
- the assembly comprises a fixed frame provided with at least one mounting hole having the shape of a buttonhole and a sash provided with at least one mounting hole having the shape of a buttonhole, in which the means for mounting the first wing and the means for mounting the second wing each comprise at least one stud, the buttonhole shape of said at least one hole in the frame being arranged head to tail with respect to the buttonhole shape of said at least one hole in the sash.

The object of this presentation and its advantages will be better understood on reading the detailed description given below of various embodiments given by way of non-limiting examples. This description refers to the pages of appended figures, on which:

The shows a perspective view from the front of two walls on which the hinge of the is mounted according to an exemplary embodiment of the invention;

The shows a rear view of the hinge mounted on the two walls of the ;

The shows a side view of a hinge mounted on two walls according to another embodiment of the invention;

The shows a front view of the two walls on which the hinge of the is mounted.

As shown in Figures 1 to 5 and designated by the general reference denoted 10, a hinge or equivalent (eg hinge, plug, hinge, etc.) is used in association with walls which are here respectively a frame 20 and an opening 22 , on which the hinge is intended to be mounted, thus making it possible to open and close the leaf 22 with respect to the frame 20. It will be noted that the role of the walls illustrated in the figures can be reversed in other embodiments and, for example, frame 20 may be a sash, while sash 22 may be a frame.

Hinge 10, sash 22 and frame 20 together form a functional assembly denoted 30.

The hinge 10 more particularly comprises two wings, namely a first wing 12 and a second wing 14 ( ) which each respectively comprise a knuckle 12a and two knuckle 14a, 14b known per se and cooperating with each other in a known manner to assemble the hinge. It will be noted that other wing configurations with a different number of knuckles can be envisaged.

The hinge 10 also comprises a pin or rod 16 which extends in an axial direction, here denoted Z (the axial direction is generally vertical although other orientations may be suitable), which provides the mechanical connection between the knuckles of the two wings and therefore between the two wings. The pin 16 constitutes the axis of rotation of the hinge thus formed. The first wing 12 and the second wing 14 are thus configured to pivot relative to each other around the axial direction Z.

Each wing extends here in a substantially planar manner in two directions of extension, the first direction of which corresponds to the axial direction Z and the second direction denoted Y is perpendicular to the axial direction Z ( ).

As shown on the , the hinge 10 comprises mounting means which are configured to mount at least one of the two wings 12, 14 on one of the two walls which are the fixed frame 20 and the opening 22. In the example embodiment illustrated in the figures the means for mounting the hinge are configured to mount each of the two wings 12 and 14 on one of the two walls 20 and 22, namely the first wing 12 on the wall 20 and the second wing 14 on the wall 22.

More particularly, the mounting means of each wing comprise one or more studs which each extend along a direction of length X ( ), also called mounting direction, which is perpendicular to the first wing extension direction (Z axial direction) and the second wing extension direction Y.

In the embodiment illustrated in the figures each wing 12, 14 is provided with two mounting studs P1, P2, for the wing 12 on the one hand, and P3, P4, for the wing 14 on the other hand . The two studs of the same wing are here aligned along the axial direction Z. In this example, the studs are all identical and only the description of the stud P1 will be given below.

The stud P1 comprises a body P1.1 which extends from the wing 12 to which it is attached (or of which it is an integral part in another embodiment), along the direction of length X and away from the wing, up to a P1.2 head which is arranged opposite the wing in relation to the body.

As shown on the , the head P1.2 forming the distal end of the stud P1 is wider than the body P1.1 in a plane defined by the directions Y and Z and, in the example shown, the width or transverse dimension of the body increases progressively along the direction of length X, from the wing 12 to the head P1.2. As more particularly represented on the , the stud P1 has a cross section of circular shape and the body P1.1 of the stud has a generally frustoconical shape whose base is formed by the head P1.2 of the stud. However, other alternative forms of stud with increasing cross-section may be suitable, the stud possibly for example having a flared external shape with a concave profile.

For mounting the hinge 10 on the frame 20 and the sash 22, each of these walls has as many mounting holes as each of the wings has mounting studs, namely here two in the embodiment described.

The represents the two walls 20 and 22 or portions of these walls against which the hinge 10 is arranged for its mounting on the latter. Alternatively, the can represent two plates on which the hinge is intended to be mounted.

In the exemplary embodiment illustrated in the , the wall 20 has two mounting holes T1 and T2 and the wall 22 has two mounting holes T3 and T4. The mounting holes are all identical and only mounting hole T1 will be described below.

Each mounting hole provided (for example by cutting) in a wall or a plate here has the general shape of a buttonhole which is produced, for the hole T1, in the form of a hole passing through the wall or the plate in its thickness and which comprises two adjacent hole portions or zones communicating with each other:
a first portion or zone of hole T1.1 which is configured, in particular here by its width (dimension in a plane defined by the transverse directions Y and Z), to allow the insertion of the head P1.2 of the stud P1 according to the length direction X of the pad;
-a second portion or hole zone (not visible on the because hidden by the engaged stud inserted in this portion but visible in the embodiment of the ) which communicates with the first portion or zone T1.1 to allow the body P1.1 of the stud to move (by sliding) in a direction transverse to the direction of length X (in this example the direction of movement is the axial direction Z since the two portions or hole zones are aligned in this direction), from the first portion T1.1 to the second portion.

The second portion masked by the head P1.2 of the stud P1 on the is configured, in particular here by its width (narrow portion with respect to the first widened portion T1.1), to prevent the passage of the head P1.2 along the direction of length X of the stud, thus opposing the removal of the stud P1 in this direction, as soon as the body P1.1 of the stud ( ) is engaged in this second portion, as shown in the . The two portions of the through hole T1 are here circular.

The frustoconical shape of the studs (or more generally their general flared shape from the wing towards the head of the stud) allows the wall formed by the frame 20 and/or by the opening 22 to be positioned between the wing 12, 14 of the hinge and the head of the block considered and thus to maintain the wall against the wing. This tapered shape of the studs also makes it possible to adapt to a whole range of wall thicknesses for a given stud shape and length and to be able to block any relative movement between wall and wing along the stud axis (direction of length X). The cutout of the T1 mounting hole to accommodate the P1 pedestal is adapted according to the thickness of the wall.

By way of example, each stud can have a length of 2.5 mm, a diameter of 7.8 mm at the level of the wing and a diameter of 11.8 mm at the level of the head and can adapt to a range of wall thicknesses (eg: sheets) of between 0.3 and 2.2 mm. Other dimensions of studs in cooperation with other wall thicknesses are of course possible.

It should be noted that at least two studs are necessary to block the rotation of the hinge wing along the axis of the stud. The presence of more than two studs per wing ensures better mechanical strength and a better distribution of forces on the hinge wing. A hinge system with a stud and a rivet or a stud and a screw to block rotation is also possible. In such a case the rivet or the screw is capable of blocking a rotation and a translation.

According to a variant embodiment (not shown) with two studs per wing or more than two studs per wing), the studs do not necessarily all have the same tapered shape and the same length. They may also not all be aligned vertically (in the case of an arrangement with a vertical pin in the knuckles) and may be oriented differently.

It will be noted that what has just been explained also applies to a plate on which the hinge is mounted and which can then be attached against one of the walls.

As shown on the , the buttonhole shape of the hole T1 of the frame 20 is arranged head to tail with respect to the buttonhole shape of the hole T3 of the opening 22 (it is the same for the holes T2 and T4). This arrangement, (assuming the spindle is vertical), makes it possible to maintain the studs in their buttonhole thanks to the forces generated jointly between the sash and the frame. The weight of the sash 22 pushes upwards, therefore the buttonholes on the sash 22 have the widened part arranged at the bottom and the resulting force on the frame 20 pushes down, therefore the buttonholes on the frame 20 have the enlarged part arranged at the top.

Such an arrangement can be omitted in the case of an assembly with a horizontal pin. Indeed, in such an assembly there is no effort in the direction of clipping of the buttonhole, so the direction of assembly does not matter.

The shows a rear view of the , thus showing the rear face of the hinge 10 which is opposite to the front face pressed against the large faces of the walls 20 and 22.

In this embodiment, each stud can be made in the form of a drilled rivet (by deformation) or a semi-drilled rivet which can be seen, on the , the rear end opposite the head of the stud. However, the stud can alternatively be welded, screwed, crimped, glued...

As shown in Figures 2 and 3, each wing 12, 14 of the hinge comprises a through hole t1, t2 which also passes through the thickness of the facing wall and which is configured to receive a locking member, for example a rod , a screw or a rivet in order to lock the assembly of the wing considered with the facing wall (frame or opening), thus preventing the dismantling of the hinge. In the example illustrated in the figures, the hole t1 is left free while the hole t2 receives a rivet R whose head can be seen on the rear face on the .

Other means for locking the assembly of the wings with the associated walls can be used in place of the locking means described above or in addition thereto.

Such other locking means comprise for example a blocker which is configured to engage in the first widened portion T1.1 of the hole T1 when the stud is engaged in the second narrower portion of the mounting hole, thus blocking the stud in this last portion by preventing it from returning in the first portion T1.1.

This type of blocker can for example be made in the form of a cap or a pop rivet.

Figures 4 and 5 illustrate another embodiment of a hinge 10' also comprising two studs P'1, P'2 on the first wing 12' and two studs P'3, P'4 on the second wing not visible on these figures and knuckles 12'a and 12'b for the 12' wing and knuckles 14'a, 14'b and 14'c for the wing 14' (number, configurations and lengths different from those of the knuckles of the previous figures).

The from the side shows the general flared shape, here frustoconical, of the studs which allows them to interface with walls of different thicknesses for the same stud. The studs thus protrude beyond the wall which they pass through by their opening portion which is more or less extended depending on the thickness of the wall passed through.

On the the two walls 20' and 22' are each provided with two mounting holes T'1, T'2 and T'3, T'4 respectively of the same configuration as those of the except their orientation which is reversed.

In this figure, the mounting studs P'1, P'2 of the first wing 12' and P'3, P'4 of the second wing were initially inserted respectively into the widened portions of the mounting holes along the axis X ( ), then moved by (lateral) sliding in the narrowed portions of these holes and a blocker B1, B2, B3 and B4 was then engaged in the widened portion of each hole in order to lock the assembly of the studs in the wall concerned and therefore ensure the locking of the wings of the hinge. Such a blocker can be a stopper or a pop rivet for example.

Although the present invention has been described with reference to specific embodiments, it is obvious that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In particular, individual features of the different illustrated/mentioned embodiments can be combined in additional embodiments. Accordingly, the description and the drawings should be considered in an illustrative rather than restrictive sense.

It is also obvious that all the characteristics described with reference to an assembly method can be transposed, alone or in combination, to a device, and conversely, all the characteristics described with reference to a device can be transposed, alone or in combination, to a assembly process.
