Description

GOND WITH A STUD ADAPTED TO ACCOMMODATE IN A HINGE OF AN OPENING ELEMENT,

  IN PARTICULAR OF A PORTAL The invention relates to a hinge provided with a stud adapted to be housed in a hinge of an opening, in particular a portal.

  Current hinges conventionally include: - a plate relative to which orthogonally extends a post, pierced with oblong holes for fixing said plate on a frame, formed with their parallel longitudinal axes so as to allow adjustment of the position of the plate along a first adjustment axis (x) parallel to the longitudinal axes 10 of the oblong orifices, - and a stud-carrying head pierced with a longitudinal bore capable of accommodating the post and comprising blocking means capable of securing said head dowel holder on said lug so that the dowel extends parallel or orthogonally with respect to the first adjustment axis (x) with a latitude for adjusting the position of the dowel head head along a second adjustment axis (y ) parallel to

  the longitudinal axis of the post and orthogonal to the first adjustment axis (x).

  These hinges allow, when installing an opening leaf such as a gate, to adjust the balance of the latter by playing on two adjustment axes consisting of the two adjustment axes (x), (y), mentioned above. . In addition, depending on the shape of the stud and the design of the means for locking the stud head on said stud, these hinges can allow, from a single hinge model, to position the stud so that the latter extends along one or the other direction along the axis (x), or even also along one or the other direction along an axis (z) orthogonal to the axes

(x) and (y).

  Thus, such hinges lead to correcting the defects of balance of the opening. In addition, their design tends to minimize the number of models of a given hinge type necessary to adapt to all installation conditions. With a view to reducing the number of models required, a hinge described in French patent FR 2,796,979 has also been designed, with a basic design similar to that of the hinges described above, but on the one hand including the plate is pierced with three coaxial axial holes, and on the other hand, the tenon constitutes a separate piece of the plate, pierced with a threaded bore capable of allowing it to be fixed on the plate by means of a fixing screw housed in any of the holes in

said platinum.

  The present invention aims to provide a basic hinge design derived from that of the hinges described above and has the main objective of providing 10 such a hinge which, once an opening placed on its hinges, offers possibilities of adjustment of the final position of the stud of this hinge according to three orthogonal adjustment axes.

  Another object of the invention is to provide a hinge making it possible to apply, from the same hinge model, several arrangements of the stud of this hinge.

  Another objective of the invention is to provide a hinge made up of distinct parts assembled one on the other but having the rigidity of a

hinge made in one piece.

  To this end, the invention relates to a hinge comprising: a plate pierced on the one hand with oblong orifices for fixing said plate to a frame, formed with their parallel longitudinal axes so as to allow adjustment of the position of the plate according to a first adjustment axis (x) parallel to the longitudinal axes of the oblong orifices, and on the other hand of an orifice for fixing on the plate a stud adapted to extend orthogonally to said plate, and provided with a longitudinal bore capable of accommodating a screwing member, - and a stud-carrying head pierced with a longitudinal bore capable of accommodating the stud, and comprising blocking means capable of securing said stud-carrying head on said post so that the stud extends parallel or orthogonally with respect to the first adjustment axis (x), with a latitude for adjusting the position of the stud head along a second adjustment axis (y)

  parallel to the longitudinal axis of the post and orthogonal to the first adjustment axis (x).

  According to the invention, this hinge is characterized in that: the orifice of the plate for fixing the post consists of an oblong orifice with a longitudinal axis (z) orthogonal to the first and second adjustment axes (x), ( y), - the longitudinal bore of the post consists of a through bore capable of accommodating a screwing member provided with an accessible operating tip 10 from the end of the bore opposite to the plate, - and the head dowel holder is pierced with a longitudinal through bore capable of maneuvering by means of a tool the maneuvering tip

of the screwing member.

  In addition to the two adjustment axes (x), (y) offered by current conventional hinges, the hinge according to the invention is designed to offer a third adjustment axis (z) orthogonal to the axes (x), (y). , due to the possibility of moving the post

  along the long axis of the oblong orifice for fixing said tenon on the plate.

  In addition, and in an essential manner, as well as the fixing members (fixing screw of the plate on a support, means for blocking the head 20 with a stud holder on the post) allowing the positioning adjustment along the axes (x ), (y), the member for screwing the post onto the plate is accessible after the opening of the leaf on the hinge, so that all the adjustments, according to the three axes (x), (y), ( z)

  can be made once the sash is in place.

  According to a first preferred embodiment, the plate has a rectangular shape and has oblong orifices, for fixing said plate, formed with their longitudinal axes parallel to the sides

longitudinal of this plate.

  On the other hand, according to a second variant embodiment, the plate, also of rectangular shape, may include oblong orifices, for fixing said plate, formed with their longitudinal axes orthogonal to the sides

longitudinal of this plate.

  Furthermore, advantageously, the orifice for fixing the post on the plate forms a countersink formed at the rear face of said plate and capable of accommodating a nut, the screwing member consisting of a fixing screw provided a

  operating head and a threaded rod capable of being screwed into the nut.

  According to another advantageous characteristic of the invention, the tenon consists of a cylindrical tenon provided with a peripheral wall on which are formed at least two longitudinal flats inclined longitudinally so as to have inverted slopes. In addition, the stud head is then pierced with a cylindrical bore of circular section conjugate with the external diameter of the stud, and comprises locking members adapted to come to bear and lock on the

tenon flats.

  The design of these means for locking the stud head head 15 on the tenon makes it possible to guarantee against any relative displacement of these two elements,

  fact that the blocking is ensured by blocking members bearing on two flat faces inclined according to inverted slopes, some thus prohibiting any movement of the head in the direction of the plate, and others preventing any movement of the tending head, in particular under the effect of the weight of the leaf suspended from the hinge, to move it away from the plate.

  According to another advantageous characteristic of the invention, the plate and the tenon comprise notches formed respectively on the periphery of the orifice intended for the fixing of the tenon, and on one of the end end faces of said tenon, and adapted to cooperate so as to prevent a possible rotation of the post, and a possible movement of said post along the axis (y).

  Such notches allow to perfectly immobilize the post relative to the plate, and thus lead, in combination with the above-mentioned arrangements for immobilizing the stud head head, to produce a hinge whose

  rigidity is comparable to that of a hinge made in one piece.

  According to a first advantageous alternative embodiment, the post has at least two flats formed at the level of generatrices of the wall

  peripheral of said post extending along two perpendicular diametrical planes.

  This arrangement allows, in effect, by simple rotation of the head 5 stud holder around the post, to arrange the stud so that it extends in one or the other direction along any of the axes ( x) and (z), and this by means of locking members positioned and in a suitable number to come to bear on the flats

  in either of these four positions.

  According to a second advantageous alternative embodiment aiming at the same objective (possible quadruple positioning of the stud) the tenon comprises at least two flats formed at the level of diametrically opposite generatrices of the

peripheral wall of said post.

  Another advantageous embodiment consists in combining the two variants described above and therefore advantageously in making a hinge, the tenon of which comprises four flats distributed around the periphery of the peripheral wall of said tenon and formed so that two flats formed at the level generators

  diametrically opposite have inverted slopes.

  Other characteristics, objects and advantages of the invention will emerge from the detailed description which follows, with reference to the appended drawings which, by way of non-limiting example, represent a preferred embodiment. On these

  drawings: - Figure 1 is a perspective view, in exploded mode, of the components of a hinge according to the invention, - Figure 2 is a longitudinal section of this hinge by a plane 25 A, on which the stud is shown pivoted by 900 relative to the stud shown in Figure 1, - Figure 3 is a partial longitudinal section of the stud assembly / stud head head of this hinge, by a plane B passing through the axis of the screws blocking of said stud head on said tenon, FIG. 4 is a front view of the base of the tenon of a hinge according to the invention,

  - And Figures 5 to 8 are schematic perspective views showing four separate arrangements of a hinge according to the invention.

  The hinge according to the invention shown in the figures is intended to carry in a rotary manner an opening such as a portal, and adapted to allow the vertical alignment of this opening, once the latter is put in place, by playing on three axes of

orthogonal adjustment.

  (For the purpose of simplifying the terminology, the hinge according to the invention is described below, being assumed to be in its fixing position on a frame, the edges of the plate therefore extending respectively horizontally and vertically).

  This hinge comprises, firstly, a plate 1 of rectangular shape shown, arranged horizontally, that is to say with its longitudinal sides 15 extending horizontally.

  This plate 1 is, in the first place, pierced by two oblong holes 2, 3 centered on the longitudinal axis of symmetry of said plate, and whose major axes extend parallel to the longitudinal sides of this plate 1. These two oblong holes 2, 3 are intended to allow the passage of fixing screws (not shown) 20 of the plate 1 on any support, by providing a latitude for adjusting the position of this plate 1 along a first horizontal adjustment axis (x), as shown in the figures to 8. These two oblong holes 2, 3 are, moreover, formed, the first 3 in the vicinity of one of the vertical edges of the plate 1, and the second 2 substantially offset from the vertical axis of symmetry of this plate 1, opposite this axis

  of symmetry with respect to the first oblong hole 2.

  -The plate 1 is, in addition, pierced with a third oblong hole 4 whose major axis extends vertically along an axis (z), arranged so as to be focused on the length portion of the plate 1 extending between the second oblong hole 2 and the

  vertical edge of said plate opposite the first oblong hole 3.

  This oblong hole 4, intended for fixing the post on the plate 1, splits, in the thickness of said plate, into a lumen 5 formed in the half5 thickness of plate 1 from the front fax machine before the latter. , of width adapted to allow the passage of a fixing screw, and a slot 6 formed in the other half-thickness of the plate 1, from the rear front face of this

  last, of suitable width to accommodate and lock in rotation a nut.

  In addition, the front end face of the plate 1 has on the 10 periphery of this third oblong hole 4, a notched grating 7, that is to say formed of diamond point studs delimiting series of respectively horizontal grooves

and vertical.

  The hinge according to the invention further comprises a pin holder head 8 formed of two blocks machined in one piece: a first block 9 of rectangular rectangle shape adapted to come into abutment against the front end face

  of the plate 1, extended by a second cylindrical block 10 of axis of revolution perpendicular to the longitudinal axis of symmetry of the rectangular parallelepiped block 9.

  In addition, the four longitudinal sides of the first block 9 are bevelled so as to present chamfers such as 11, 12 sections at 45.

  This stud head head 8 is, moreover, pierced with a bore

  longitudinal cylindrical 15 formed axially in the first block 9 and extending into the second block 10, outside of which it opens through an orifice 16 formed axially with respect to said bore and of section adapted to allow insertion inside this bore 15 of a tool shank such as a screwdriver or an hexagon wrench.

  The stud head 8 is also pierced by two threaded orifices such as 17 opening into the bore 15, formed opposite in two diametrically opposite chamfers 11, 12 of the first block 9, so as to extend along

  an oblique axis inclined by 45 relative to the faces of said first block.

  This stud holder head 8 finally comprises a threaded bore 18 formed axially in one of the bases of the second block 10, adapted to allow the fixing on said head of a cylindrical stud 19 provided for this purpose with an end section. 20 threaded diameter smaller than the current diameter of said stud combined with that of said threaded bore 18. The hinge according to the invention finally comprises a lug 21 having the shape of a cylindrical tubular sleeve of external diameter substantially smaller than the internal diameter of l bore 15 of the stud head 8, of

  so as to provide a clearance allowing the introduction of said stud in said bore.

  This tenon 21 comprises, first of all, a front face 22

  notched having a series of parallel notches combined with the notch 7 of the plate 1.

  As mentioned above, this stud 21 consists of a tubular sleeve therefore pierced with a longitudinal bore 23 passing through. This bore 23 is further subdivided into two longitudinal sections 23a, 23b of frustoconical shape separated by a radial shoulder: a first section 23b of smaller section adapted to allow the passage of the threaded rod of a fixing screw 28, and emerging at the level of the notched fax machine 22 of this stud 21, and a second section 23a of section greater than that of the

  first section 23b adapted to accommodate the head 29 of a fixing screw.

  This stud 21 is, moreover, machined so that its peripheral wall 20 has four longitudinal flats 24-27 centered on generatrices extending in two perpendicular diametrical planes offset by 450 relative to the

  notches 22 of the front face of said stud.

  These flats 24-27 are, moreover, arranged so that two diametrically opposite flats, respectively 24-26, 25-27 are formed according to parallel cutting planes inclined longitudinally by the same angle of the order of a few degrees relative to the longitudinal axis of the post 21. Thus formed, the flats 24-26, 25-27 have, from one or the other end face of the front post

21, reverse slopes.

  The fixing of the pin 21 on the plate 1 is ensured by means of a clamping screw 28 provided with a hexagon socket head 29 adapted to come to be housed in the section 23a of the bore 23 of said pin, in abutment against the radial shoulder of said bore, and of a threaded rod of section adapted to extend in the section 5 23b of the bore 23, and of length adapted to be screwed into a nut 30 housed in

  the lumen 6 of the third oblong hole 4 of the plate 1.

  The attachment of the stud head 8 around the lug 21 is ensured by means of two needle type screws 31, 32 adapted to be

  screw into the holes 17 of said stud head 8.

  First, and as shown in FIGS. 5 to 8, the hinge according to the invention makes it possible to orient the stud 19 so that it extends in either direction, either along an axis ( x) parallel to the longitudinal axis of the plate 1,

  either along an axis (z) orthogonal to said longitudinal axis of the plate 1.

  For this purpose, it should be noted that, although the stud 19 is shown oriented horizontally in FIGS. 6 and 7 and oriented downwards in FIG. 8, and this for the purpose of illustrating the different positions that can take said stud relative to the plate 1, it is understood that the hinge according to the invention is designed so that this stud 19 systematically extends vertically and is oriented upwards, this position being obtained, for the assemblies of FIGS. 6 and 7 by placing the plate 1 vertically, and for the assembly of FIG. 8 by turning over from

1800 said platinum.

  These four orientations of the stud 19 can, in addition, be obtained by subjecting the stud head head 8 around the stud 21 by a simple rotation, and are automatically indexed because the locking screws 31, 32 cannot ensure a locking of said stud head in rotation only when their end

  bears on a flat face, that is to say on one of the flats 24-27, of the stud 21.

  Secondly, the hinge according to the invention offers three orthogonal adjustment axes with a view to adjusting the position of the opening once it

set up on its hinges.

  Indeed, the position of the stud 19 can be adjusted along a first adjustment axis (x) thanks to the oblong shape of the orifices 2, 3 for fixing the

deck 1.

  The position of the stud 19 can also be adjusted along a second adjustment axis (y) by displacement of the stud head 8

  longitudinally along the post 21.

  Finally, the position of the stud 19 can also be adjusted along a third adjustment axis (z) thanks to the oblong shape of the third orifice 4 of the plate 1, which allows the tenon assembly to be moved along this axis (z). 21 / door head 10 stud 8.

  It is, moreover, essential to note that, as mentioned above, all these adjustments are authorized once the opening is put in place on its hinges, because all the fixing members (fixing screw of the plate 1, screw fixing 28 of the stud 21 on the plate 1, and locking screw 31, 32 of the stud head 8 on the stud 21) are accessible without requiring any disassembly of any part of the hinge.

  Thirdly, once all the adjustments have been made, the hinge according to the invention can be assimilated to a hinge made in one piece due to the perfect immobilization, one with respect to the other, of the various parts constituting it,

  guarantee against any relative displacement of an element compared to another.

  Indeed, and on the one hand, the pin 21 is perfectly immobilized relative to the plate 1, due to the notches 7 and 22 which guarantee

  against any sliding downwards and any possible rotation of said tenon.

  In addition, and on the other hand, any relative movement of the stud head 8 relative to the stud 21 is also prohibited, since the blocking of this stud head head 8 is ensured by two coaxial screws 31, 32 bearing on two flat faces (flats 24-26 or flats 25-27) inclined longitudinally on inverted slopes. Thus, in fact, any movement of the stud head 8 in the direction of the plate 1 is prohibited by the clamping screw 31 or 32 bearing on the flat 24-27 forming a dihedral of obtuse angle with the front face of said platinum. Likewise, any movement of the stud head 8 tending to move it away from the plate 1 (the most frequent case observed with the current hinges, resulting from the tensile force exerted on the hinge due to the weight of the opening) is prohibited by the clamping screw 32 or 31 bearing on the flat 24-27 forming a dihedral angle at the acute apex with the front face of said plate.
