Description

Field of the invention The present invention relates to a shutter hinge device consisting of a hinge provided with holes for fixing to the shutter and a counter-hinge provided with holes in positions corresponding to those of the holes in the shutter. hinge as well as assembly members for joining the hinge and the counter-hinge and the panel of the sandwich shutter, STATE OF THE ART Multiple embodiments of hinges and counter-hinges generally assembled by pan screws are known. coming to rest against the hinge and passing through the shutter panel to emerge from holes in the counter-hinge and receive a nut, or even a blind nut.

These different embodiments of shutter hinges 15 have the drawback of being very apparent when the shutter is open and the back of the shutter, which is then visible, is particularly noticeable because of the nuts of the screws fixing the hinges to the counter-pieces. hinges.

The nuts are also exposed to the elements and to the infiltration of rainwater by capillary action between the counter fitting and the nut to reach the threaded part of the screw.

It also facilitates the infiltration of water inside the shutter panel along the thread, by migrating moisture along the thread.

This presence of humidity is all the greater as the bore which receives the screw is smooth and thus leaves an air gap between the thread of the screw and the bore.

The different types of known hinges also have the drawback of not being adaptable to different thicknesses of shutters nor of being easy to install.

Each type of shutter thickness requires a different hinge for each type of shutter thickness.

In addition, these hinges are not easy to install.

In addition, the screws in relief can be inconvenient for the appearance of certain types of buildings seeking the simplicity of the forms.

In addition, this type of closure is not reversible, that is to say that the screw and the nut are always on a determined face 2 of the shutter: the screw is on the side of the hinge and the nut is on the side of the counter-hinge.

If the screw may have a relatively flat head like a so-called pan screw, the nut constitutes a highly raised element, whether it is a simple nut or a cap nut.

Since the counter-hinge is visible when the shutters are open, in certain cases there will be the drawback of having very visible nuts since they are in relief.

Aim of the invention The aim of the present invention is to remedy the drawbacks of known solutions and to develop a shutter hanging device which is particularly not very visible when the shutter is open, adaptable to all the thicknesses of shutters and if possible reversible.

Ex and Ervantakes of the invention To this end, the present invention relates to a shutter hinge device comprising: - a hinge provided with non-circular holes for fixing to the shutter, a counter-hinge, provided with holes in corresponding positions to those of the hinge, - assembly members for assembling the hinge and the counter-hinge through the shutter panel passing through the holes in the hinge and those in the counter-hinge, each assembly member comprising: ^ a socket made up of: ** a flat head without recess, ** a sleeve with internal thread, of length less than the thickness of. panel, * a non-circular collar under the flat head, at the base of the threaded sleeve, of shape and dimensions complementary to those of the non-circular holes of the hinge for the rotation blocking, a flat head screw for screwing in the threaded sleeve engaged in a hole in the panel through the corresponding hole in the counter-hinge.

The shutter hinge device according to the invention has the advantage of allowing a particularly firm and inconspicuous connection between the hinge, the counter-hinge and the assembly members, bringing together these three elements so as to take the shutter firmly in. sand- s wich between the hinge and the counter-hinge.

The hinge according to the invention is simple, adaptable to different thicknesses of shutters which, in general, are between 20-45 mm, thanks to the latitude offered by the combination of the sleeve and the screw since the screwing is housed in the thickness of the shutter.

The socket size is preferably slightly less than the smallest shutter thickness chosen for the compatibility range of shutter thicknesses, the length complement to the thickness of the shutter being achieved by the length of the shutter. screw.

The shape of the non-circular holes of the hinge and that of the collar of the sleeve are complementary in the direction of the locking in rotation of the sleeve, which allows other variations of shape than the simple assembly of a positive shape and of the sleeve. 'a negative form.

Thus and by way of example, a rectangular hole in the hinge and a square collar are complementary shapes within the meaning of the invention since their assembly blocks the rotation of the sleeve.

A rectangular hole or more generally elongated in the longitudinal direction of the hinge offers the advantage of making it possible to absorb the expansion of the hinge exposed to strong sunlight.

This prevents the expanding hinge exerting excessive forces on the shutter which could crack it.

Such a hinge will preferably have a hole fitted over the hinge side collar and the other elongated holes to absorb expansion while maintaining a fixed point between the hinge and the shutter.

The counter-hinge will have holes shaped to match that of the hinge to allow expansion to be balanced although both sides of the shutter are not exposed to the sun at the same time.

Finally, the assembly of the screw and the sleeve is done very simply since the sleeve is locked in rotation by its engagement through the hinge and the threaded sleeve is itself held in the bore of the shutter.

It is then sufficient to pass the screw through the homologous hole of the counter-hinge to arrive almost automatically in the threaded sleeve and to continue screwing, for example using a screwdriver.

The subject of the invention is also a shutter hinge device comprising: 5 - a hinge provided with non-circular holes for fixing to the shutter, - a counter-hinge, provided with holes in positions similar to those of the hinge, - assembly members for assembling the hinge and the counter-hinge through the shutter panel passing through the holes in the hinge and those of the counter-hinge, each assembly member comprising: a screw made up of: ** a flat head without indentation, ** a threaded body, of length less than the thickness of the panel, ** a non-circular collar under the flat head, at the base of the threaded body, of shape and dimensions complementary to those of the holes in the hinge to be locked from rotation, a flat head socket with a recess to receive the threaded body engaged in a bore in the panel and screwed through the mating hole in the counter-hinge.

This hinge device has the same advantages as those developed above. This is the screw / sleeve inversion of the hinge device developed above.

Advantageously, the counter-hinge has circular holes and the screws have a circular collar of the same diameter as that of the circular holes of the counter-hinge, which allows clearance-free assembly between the screws and the counter-hinge. hinge since the screw is engaged without play in the counter-hinge and is blocked by the sleeve, 30 clicks itself housed without play in the non-circular hole of the hinge.

According to another advantageous characteristic, the counter-hinge has a hole enveloping the circular collar of the screw.

Particularly advantageously, the screw has a collar of the same diameter as the threaded sleeve of the sleeve and the collar of the sleeve is polygonal in shape circumscribed by the threaded sleeve.

A circumscribed shape within the meaning of the present invention means that the sides of the polygonal, preferably regular, shape are tangent to the contour of the threaded sleeve.

Particularly advantageously, the hole in the cantilever and the hole in the counter-hinge are of identical polygonal shape and the collar of the sleeve is of polygonal shape inscribed in the polygonal shape of the hinge and the counter-hinge. , the collar of the screw being of circular shape inscribed in the polygonal shape of the holes of the hinge and the counter-hinge. to This combination of shapes ensures all the advantages of assemblies described above and additionally adds the reversibility of the sleeve and the screw, Thus the sleeve can. be engaged in the counter-hinge and the screw in the hinge, which modifies the appearance of the shutter in the closed position or in the open position, thus making the appearance of the shutter in the open position particularly smooth, compatible with certain requirements aesthetic.

This possibility of reversing the bushes and screws in no way modifies the compatibility of the shutter hinge device for different shutter thicknesses.

According to another advantageous characteristic, the hole of the hinge and the hole of the hinge are identical, of polygonal shape, and the collar of the sleeve is of polygonal shape inscribed in the polygonal shape of the holes of the hinge and of the hinge. counter-hinge, the collar of the screw is of circular shape inscribed in the polygonal shape of the holes of the hinge and the counter-hinge.

The flat head screw has the advantage not only of being very inconspicuous on the corresponding face of the shutter but also of effectively covering the hole of the counter-hinge and thus reducing or even avoiding the penetration of moisture between the counter-hinge. hinge, screw head and screw body inside the hole in the shutter panel.

According to another advantageous feature, the flat head has a square shape with curved edges and a domed top joining the edges leaving a small thickness.

This form of flat head not only has the advantage of being itself thin thanks to the convex shape, the thickest part of which corresponds to the base of the socket and the collar and on the other hand, of hardly offer a grip to a tool such as pliers in an attempt to force the socket from the outside when the shutter is closed.

5 According to an advantageous characteristic, the non-circular collar has a square shape, which is a very simple embodiment and offers excellent resistance to locking in rotation of the sleeve with respect to the hinge, especially since the non-circular holes of the hinge are advantageously complementary, of dimensions 10 complementary to those of the collar of the sleeve.

Figure 1 shows a P-panel shaped door shutter V fitted with two or three hinges on the front DV of the shutter (side facing the wall when the shutter is open or visible side when the shutter is closed).

These hinges are each combined with a counter-hinge 2 on the other side DO (back of the shutter) of the shutter thus held sandwiched between the pairs of hinges 1 and counter-hinges 2 to be hung on the hinges.

FIG. 1 shows a part of the shutter V open revealing the front face DV of the shutter with a hinge 1 fixed to the panel P by four assembly members 3, the square head of which can be seen 311.

Figure 2, in its parts 2A, 2B, 2C, shows the detail of the hinge 1 and the counter-hinge 2.

Fig. 2A is an enlargement of the hinge 1 showing the square shaped hole 12 with the hole PC in the panel P and the threaded sleeve 313 of the socket 31 cut away.

It also shows for the next hole, the flat head 311 of the sleeve 31 placed in the hinge.

According to FIG. 2B, the hinge 1 has a node 11 to receive a hinge and four fixing holes 12.

These non-circular holes 12 30 are of oblong or polygonal shape, in particular square to receive the sockets 31 of the fasteners 3.

The hinge 1 is applied against the front DV of the shutter V.

According to FIG. 2C, the counter-hinge 2, of similar or simpler shape than that of the hinge 1, does not have a knot and is used to hold the panel P on the front hinge DV, The 8 counter-hinge 2 has fixing holes 22 in positions corresponding to those of the holes 12 of the hinge 1 but of polygonal shape, for example square to each receive the. screw 32 of an assembly member 3.

Figure 3 is a sectional view according to Figure 1 showing the structure of the panel assembly P by the hinge device 100 composed of the hinge 1 and the counter-hinge 2 or a member having the same function of 'support, as well as assembly members 3.

This is made up of a sleeve 31 and a screw 32 1 () passing through the hinge 1, the PC hole in panel P and the counter-hinge 2.

The bush 31 has a flat head 311 without a recess, carrying a sleeve 313 with an internal thread.

A square collar 312 lines the underside of the flat head 311 at the base of the threaded sleeve 313.

The square collar 312 has the same shape and the same dimensions as the holes 12 of the hinge 1 or vice versa and more exactly, the collar 312 preferably imposes its shape and dimensions on the hole 12 of the hinge 1 for the simple one. because the fasteners 3 are intended for a large number of hinges which may have different aesthetic shapes and thus it is easier to adapt the shape of the holes of the hinges to the shape of the collars of the sleeves and not the other way around.

The threaded sleeve 313 receives a flathead screw 321 with a screw socket 322 and a threaded body 323 for threading into the threaded sleeve 313.

The screw 32 passes through the hole 22 of the counter-hinge 2 to be housed in the threaded sleeve 313 engaged in the hole PC of the panel P thus sandwiched between the hinge 1 and the counter-hinge 2.

Figures 4 and 5 show the bush 31 in more detail.

The flat head 311 of the socket 31 has a generally canned shape in plan view, with rounded sides 31 and a domed top 311b to thus have a very thin edge (eb).

The top 311b is smooth without indentation so as to present as little relief as possible with respect to the hinge 1 and also the least grip on a tool which would be used to force the head of the socket 31.

The collar 312 is preferably of square shape and more generally of non-circular shape so as to be locked in rotation in the hole 12 of complementary shape of the hinge 1, The thickness of the collar 312 is close to the thickness of the hinge 1.

The threaded sleeve 313 has a relatively large length L compared to the thickness (e) of the panel P to have a better hold of the assembly member 3 in the hole PC of the panel, 10 whose diameter is adjusted to that of the threaded sleeve 313, again with the aim of ensuring a practically no clearance required by closing the shutter in its bay.

Since the thickness (e) of the panels used for the shutters V is of the order of 20 mm-45 mm, it is possible to standardize the length L of the sleeves 313.

According to Figure 6, the screw 32 is preferably flat head 321 to integrate into the aesthetics of the front of the shutter DV, visible when the shutter V is open.

The screw 32 has a collar 324 to be housed without play in the hole of the counter-hinge 2 and thus hold it without play.

According to the example above, the screw 32 has a collar 324 of the same diameter as that of the threaded sleeve 313.

The collar 312 of the sleeve 31 is of polygonal shape circumscribed to the threaded sleeve 313.

This means that this polygonal shape has sides tangent to the circular shape of the threaded sleeve.

25 Particularly advantageously, the hole in the hinge 1 and the hole 22 in the counter-hinge 2 are of identical polygonal shape, and the collar 312 of the sleeve 31 is of polygonal shape inscribed in the polygonal shape of the holes. 12 and 22 of hinge 1 and counter-hinge 2.

The collar 324 of the screw 32 is of circular shape 30 inscribed in the polygonal shape of the holes 12 and 22 of the hinge 1 and the counter-hinge 2, This allows the reversibility of the assembly while ensuring the locking in rotation of the sleeve 31 and holding without play but with rotation of screw 32.

These different variants are described but are not shown in the drawings. Fig. 7 is a sectional view showing the structure of the assembly of a panel P by another embodiment of the hinge device 100A according to FIG. invention.

The hinge device 100A is composed of the hinge 1 and the counter-hinge 2 or of a member having the same support function.

These different elements are united by assembly members 3A.

The assembly member 3A is composed of a screw 31A and a sleeve 32A passing through the hinge 1, the hole PC of the panel P and the counter-hinge 2.

The screw 31A has a flat head 311A without a recess, carrying a threaded body 313A.

A non-circular collar, here square 312A adorns the underside of the flat head 31 lA at the base of the threaded body 313A.

The square collar 312A has dimensions allowing it to fit into the holes 12 of the hinge 1 and to be locked therein in rotation.

The threaded body 313A receives a threaded socket 32A with a flat head 321A with a screw recess 322A and an internally threaded sleeve 323A for screwing onto the threaded body 313A.

The bush 32A passes through the counter-hinge 2 to be screwed on the threaded body 313A engaged in the PC hole of the panel P.

Figure 8 shows, in two perspective views, the detail of the socket 32A.

This socket consists of a 321A flat head with a 322A screw socket.

The flat head 321A carries a sleeve 323A with an internal thread.

In this exemplary embodiment, there is no round collar under the flat head at the junction with the threaded sleeve, with sleeve 323A serving as a round collar.

FIG. 9, in its parts 9A and 9B, shows a screw 31A constituting the assembly member 3A with the sleeve 322 This screw 31A has a flat head 311A provided with a curved edge 311aA and a domed top 311. bA.

The underside of the head has a square collar 312A followed by a threaded body 313A.
