Description

The present invention relates to hinges.

A pivotal door is conventionally carried by hinges fixed to a frame. In order for the door to close properly, and to be locked, a good fitting accuracy of the hinges is obviously required. Even if the assembly is done accurately, it is possible that the fixtures to the frame move or deform, for example if dowels are used. It can also occur, over time, a progressive deformation of the frame itself, especially if the door is of high weight. One can for example think of a metal gate of great width.

If the door tilts slightly, it may still remain maneuvrable for some time, but the free end of its lower edge will rub on the ground, damaging it by progressive digging of a ramp, and requiring an increased effort for its maneuver .

Likewise, the planned functional distance between the bolt and the striker will be modified and their cooperation may become impossible.

In such a case, it is possible to reorient the closing position of the door by moving the fixing point of the lower or upper hinge on the frame so that one end of the geometric pivot axis, which it defines with the opposite hinge, tilts slightly relative to the frame, to restore the verticality of this axis and thus to raise the position of the free end of the door in the closed position.

It may also be necessary to reframe the closing position of the door by translating it to one side or the other or height, whether for cooperation bolt / strike or for a sealing problem to seal with the frame.

Such a displacement of the fasteners will leave traces of holes in the frame and / or the door, which, in addition to the unsightly appearance, can be sources of degradation initiators over time; for example by oxidation or other, due to moisture. In addition, this involves tedious operations.

The present invention aims at providing a solution to such a problem of adjusting the closing position of a pivotally mounted door.

The documents EP-A-0 747 557 and EP-A-1217157 each describe a hinge, comprising a first block, comprising first means for fixing to a frame and first bearing means, for axial support of second bearing support means, belonging to a second block comprising second fixing means to a door, the first and second bearing means being provided for mutually cooperating in relative rotation with respect to an axial direction of a geometric hinge axis, the first bearing means being movably mounted in axial position, within a range of adjustment predetermined axial axis extending in said axial direction, relative to the first fixing means and being associated with means for adjusting said axial position and locking means in said axial position.

For this purpose, the present invention relates to a hinge according to claim 1.

Thus, an axial adjustment of the door is effected by a displacement of the first bearing means, with respect to the remainder of the first block and therefore in particular with respect to the first fixing means. As the first bearing means support the second bearing means associated at the door, they adjust the height position of the door. It is therefore unnecessary to disassemble the first and second fastening means.

In particular, if the bearings of a hinge are used prematurely, or if the attachment thereof to the frame has not been carried out exactly to the desired height, we can easily rebalance the sharing of the weight load of the door, with the other hinges or hinges, by a height adjustment of the bearings of the hinge considered or others.

It will be understood that, while the invention is particularly useful for a room or building door, it is also applicable to other types of pivoting elements, such as windows and window or furniture shutters. that is to say, in general, any pivoting element whose part, remote from the pivot axis, must be able to occupy a predetermined position. It will be noted in particular that the precise function of this pivoting element does not come into play here, that is to say that it is not necessarily a closing element of a passage, and that it can for example be a simple rotating arm of which a part, for example of free end, must come to occupy a certain position, for example to cooperate with a fixed element. It is therefore generally a functional position, but not necessarily a closing position.

Of course, the invention is also applicable for a non-vertical axis element.

Note also that the hinge term used here is intended to cover both the hinges in the strict sense, that is to say whose two mutually articulated elements are normally inseparable, and devices said hinge, whose two elements above are simply mutually hooked and separable by axial translation.

According to the invention, the first bearing means comprise a bearing support bushing with a bearing bearing surface facing the second bearing means and with a bearing surface facing away from the bearing support surface, provided to take support on the pin.

The sleeve, or ring, can therefore translate axially, the support bearing surface being constituted for example by an upper end portion, in the operative position, of the sleeve, possibly forming a radial expansion lip to present a desired width of circular track. The bearing surface may be for example a lower edge of the sleeve.

As the locking in rotation is thus ensured at the level of the axial support provided to the support bearing sleeve, it is easy to provide to leave accessible an end of the hinge, for example slot or wheel, to exert alternating torques if the removable means of axial support, for example a pin, are somewhat stuck.

According to the invention, a gond adjusting section is provided to be rotatably mounted, and movable in axial translation, relative to the first fixing means, and comprises a support ramp, axial position adjustment, inclined with respect to a purely radial plane to said axis, provided to cooperate with a support ramp relief solidarity of the first means of fixation. The support ramp relief may be, in minimum configuration, a support tooth. Dual mounting is also possible.

In a particular embodiment, the support ramp constitutes an end surface of the section.

It is therefore a cam on which the hinge adjustment section rests, so that a rotation of the latter in a given direction pushes it in axial translation.

In another embodiment, the support ramp is a thread.

The ramp is therefore lateral and can therefore extend axially over any range of desired length.

The locking means comprise a pin arranged to be housed in a transverse hinge hole, the pin is furthermore functionally associated with rotational stop means, integral with the first fixing means, arranged to limit any parasitic rotation of the adjustment section. of hinge.

The pin is thus bi-functional, since it provides the desired axial support, possibly through a sleeve in which it is housed to protect it against the axial shear of the bearing that it supports, and that it fixes the angular position, and thus the axial position of the rotary section.

In a particular embodiment, the support bearing bushing is held in position by an end surface of a screw movable adjusting screw with axial translation relative to the first fastening means belonging to a first body, and the one of the set of elements constituted by the adjusting screw and the first body, comprises, for this purpose, a thread, axial position adjustment, provided to cooperate with a complementary relief integral with the other element of the assembly. The holding in position may be radial and / or axial.

In a variant, a hinge comprises a lateral relief of support of the support bushing and a lower end of the hinge is held in position by an end surface of a movable adjusting screw in axial translation with respect to the first drive means. fastener belonging to a first body, and one of the set of elements constituted by the adjusting screw and the first body comprises, for this purpose, a thread, axial position adjustment, provided to cooperate with a complementary relief integral with the other element of the assembly.

Said support relief is advantageously a locking pin in rotation.

In a particular embodiment, the support bearing bush is integrated integrally with the hinge adjusting section to form a screw, one end of which constitutes said bearing bearing surface and the second bearing means comprise, in addition to a support bearing surface provided to abut on said end, an axial centering relief arranged to cooperate with a surface of complementary shape of said end ensuring the function of maintaining axial bearing alignment gondola.

The bearing bearing surface, resting on the screw head, may for example be continued by a skirt surrounding the head, each being preferably circular and of the same diameter. The bearing support surface thus constitutes the bottom of a cavity open to the bottom, or cap, which laterally traps the head and thus maintains the desired axial alignment.

The support bearing bushing may be rotatably mounted, and movable in axial translation relative to the first fastening means belonging to a first body, and one of the set of elements consisting of the support bearing sleeve and the first body, comprises, for this purpose, a thread, axial position adjustment, provided to cooperate with a complementary relief integral with the other element.

The sleeve is thus screwed directly to the first body, and a free portion of its outer surface, generally cylindrical, may include a grooving, accessible to a user, constituting a control wheel, discussed below.

The axial position adjusting means are advantageously arranged to receive a rotary adjustment tool.

The tool may for example be a screwdriver, an Allen key or a flat wrench, cooperating with the adjustment means, arranged for this purpose.

The axial position adjusting means may also comprise a control wheel.

The first and second bearing means may comprise respectively first and second ramps, inclined on a radial plane to the axis, provided to cooperate to cause a repulsion in axial translation of the second block relative to the first block during a pivoting of the second ramp, in a given direction, in an angular sector occupied by the first ramp.

It can be provided that at least one of the first and second fixing means comprises a pair of complementary lateral adjustment elements constituted by a body, coupled to the first, respectively second, bearing means, and by a removable base, mounting on respectively the frame or the door, one of the elements of the pair comprising a serration, with teeth arranged in a range extending in a direction transverse to said axial direction, the other element of the pair having a complementary relief of the serration to provide a plurality of relative disjoint coupling positions, with lateral offset, between the two elements of the pair, in association with means for maintaining the coupling in any chosen position.

It is therefore a serration of several teeth that cooperates with another serration, which can be limited to a single tooth if the constraints provided are limited.

It is thus possible to perform lateral adjustment of the door by lateral translation in its plane of extension or a depth adjustment by transverse displacement to this plane, this being a function of the direction towards which the bearing surface, the frame or the the door, which receives the fastening means considered, that is to say, in particular, a slice surface or a front surface of the frame or the door. Note that the lateral adjustment elements above, and those indicated below, could be provided even in the absence of the axial position adjusting elements. Note further that, as the door is in practice carried by at least two hinges, a single hinge can be provided carrier, that is to say ensuring the adjustment of axial position, in height, the other hinge or hinges can be mounted with an axial clearance between their opposite bearings, or even returned, and then ensuring only the lateral adjustment, of registration in the intended orientation, usually vertical, of the geometric axis of pivoting the door. In particular, the axial position adjusting hinge may be free of lateral adjustment elements.

Preferably, the first and second fixing means each comprise a said pair of complementary lateral adjustment elements.

The carrier surfaces above will then preferably be chosen substantially mutually perpendicular, that is to say one of slice and the other frontal, so that one has the two degrees, mentioned above, adjustment respectively lateral and depth of the door. However, it can be provided that the base provides a return angle, can reach for example 90 degrees, between its bearing surface on the bearing surface and a direction of overall extension of a plane of the interface that it presents on the other side, that is to say a plane of extension of the serration or complementary relief.

The base advantageously comprises a relief of holding in position of the fastening means, intended to be introduced into the frame, respectively the door.

To increase the adjustment range, there may be provided an adapter shim, offset thickness of the base, having a fastener to the base, constituting an equivalent to that of the elements of the pair that belongs to the body, and having mounting means at a predetermined position on the body.

The shim, or even a set of shims of various thicknesses, thus offers a possibility of increased offset of the axis of the hinge relative to the bearing surface considered. Again, the wedge set can offer various angle references.

The complementary relief may be arranged to also be moved in one direction, extending each tooth tip, which is oblique with respect to the axial direction of hinge, so as to have, for each of the disjoint lateral offset positions, another plurality of positions forming a succession of offset positions both lateral and axial.

Each of the disjointed lateral positions, mutually distant from a serration pitch, corresponding to a certain relative axial position between the serration and the complementary relief, can thus now evolve in a fine, possibly continuous, adjustment range. For example, the directions of extension of the tops of the teeth will be essentially axial with a slight obliquity chosen as a function of the length of the tops of the teeth so that a substantially axial translation of the complementary relief over the length thereof causes a lateral shift. a step or even a few steps if we avoid the need for too frequent uncoupling of the serration and the complementary relief. Adjustment means by substantially axial relative displacement between the serration and the complementary relief will be provided to thereby cause one of these. It may for example be a lateral adjustment screw by axial pushing thereof. Retrofitting the height offset thus caused may be performed by the axial position adjustment means.

The serration can belong to a regular matrix formed by a first network of columns of said teeth which is started by a second transverse network of rows of teeth to form pyramids arranged in a matrix, and the complementary relief comprises a matrix of the same regularity, cavities receiving peaks of the pyramids.

It is thus possible to make offsets in one and / or the other of the row and column directions, which may or may not be mutually perpendicular.

The cavities can lead to a common flat surface or in valleys. In the latter case, the guidance in the direction, line or column, desired, is provided by the valley flanks.

The present invention will be better understood with the aid of the following description of an embodiment of the hinge according to the invention, with reference to the appended drawing, in which:

• the figure 1 is a perspective view of a hinge according to one embodiment of the invention,
• the figure 2 is a view, in section AA of the figure 3 longitudinal axis of the hinge, with an adjustment in the axial axial position,

With reference to Figures 1 to 3 , the hinge shown comprises a first block 11, said fixed, with a first body 120 having first elements 12 for attachment to a wall or frame 1 and first bearing elements 13, movably mounted on the first body 120 and serving as a support axial, by a bearing bearing surface 131, to a bearing bearing surface 231, belonging to second bearing members 23, constituting a support integrated with a second body 220 of a second block 21, rotatably mounted on the first block 11 and, furthermore, can be adjusted axially with respect thereto, as explained below. The second block 21 comprises second elements 22 for fixing to a rotatably mounted element, here a pivoting door 2. The first and second bearing elements 13, 23 are designed to mutually cooperate in relative rotation with respect to an axial direction 10 a geometric axis of a common axis or hinge 9.

For ease of presentation, the hinge is assumed to be in the operative position, i.e. with the substantially vertical axial direction. The various elements are therefore described with reference to this orientation. It is obvious that the description, and even the possible use, of the hinge would remain valid, after the necessary transposition, if the hinge was oriented differently.

To allow a height adjustment of the door 2 without the need to disassemble the hinge, the first bearing elements 13, and therefore with them all the second block 21 and in particular the second elements 22 for attachment to the door 2, are mounted mobile in a setting range predetermined axial axis extending in the axial direction 10, relative to the remainder of the first block 11, so in particular with respect to the first body 120 and therefore to the first elements 12 for attachment to the frame 1, which serve as absolute position reference of the hinge relative to the frame 1. There is provided a member for adjusting the axial position of the first bearing members 13, here in the form of a slot 14F accessible to a screwdriver, at the said upper end of the hinge 9. It is in further provided locking elements in the selected axial position, here comprising a pin 151 with two branches, generally β- shaped, with a rectilinear branch through a transverse hole 91, here radial and diametral direction, of the hinge 9, and a curved branch coming down on the outer surface of the hinge 9 to thereby trap and keep in place the pin 151. The pin 151 is here threaded into a short sleeve for to strengthen its resistance to axial shear caused by a support bearing sleeve 130. The sheath is however of limited length so that its removal is unnecessary during the adjustment rotation of the hinge 9.

The first bearing members 13 comprise the substantially cylindrical support bushing 130, surrounding the hinge 9, with an upper edge, or coping, constituting the bearing support surface 131 thus turned towards a homologous bearing bushing 230 of the second bearing elements. 23 bearing support surface 231. The support bearing sleeve 130 further comprises a lower portion constituting a bearing surface 133, thus turned away from the support bearing surface 131, provided to take support, to through a washer 150, on the axial support element constituted by the pin 151, which, in addition, serves as locking element in rotation of the hinge 9, when the first bearing elements 13 have reached the desired axial adjustment position , as explained below. For such locking against any misalignment rotation, the pin 151 is functionally associated with two rotational stop elements 124 ( Fig. 2 ), integral with the first fastening elements 12, arranged to limit, and even here totally inhibit, any parasitic rotation of the hinge 9, and therefore in particular of a threaded portion 92 thereof, for the axial adjustment. The rotational stop elements 124 belong to the first body 120 and have two respective axial abutment surfaces which are located in substantially an axial plane of the axial direction 10, being rotated in the same direction, and are aligned with the same side of the transverse hole 91. The rectilinear branch of the pin 151 is thus here substantially supported, by two projecting ends, on the two axial abutment surfaces, so that any parasitic movement of rotation in one direction or the other causes a reaction. of inhibition on the part of the axial abutment surface considered.

If the user wishes to make a new adjustment, and therefore wants to extract the pin 151, he can still access the adjustment slot 14F to, if necessary, exercise alternating pairs of slight rotation of the hinge 9 in order to unlock the pin 151 if it is in strong support with friction on axial abutment surfaces.

The threaded portion 92 of the hinge 9, used for the axial adjustment of the first bearing elements 13, is here a lower end section, rotatably mounted, and movable in axial translation, with respect to the first body 120, therefore in particular with respect to the first fastening elements 12, and it comprises a support ramp 93, axial position adjustment, inclined with respect to a purely radial plane to the axial direction 10, provided to cooperate with a support ramp 23 integral with the first body 120, thus also the first fastening elements 12. The bearing ramp here is a thread 93, surrounding the actual body of the threaded portion 92, engaged with a axial tapped sliding hole, located here at the lower end of the first body 120.

Alternatively, the above thread is omitted and the support ramp (93) constitutes an end surface of the hinge section 92, then not threaded, placed on a ramped bottom of the sliding hole.

In another variant, according to figure 6 it may be provided that the function of the support bearing bushing 130 is integrated integrally, or directly associated, with that of the threaded hinge adjusting section 92 to form a threaded rod 14 or bearing screw, or support of bearing (sleeve 130), independent whose body replaces the lower portion 92 of the hinge 9 as drawn. A support surface 141, upper end, top of a head 142 or, as drawn, opposite end to the head 142 here at the bottom, constitutes, in all or part, the support bearing surface 131, or , as drawn, carries the support bearing sleeve 130, the hinge 9 then being limited to an upper section 94. The second bearing elements 23, or, as drawn, the upper section 94, then preferably includes, in addition the bearing bearing surface 231 provided to bear on the screw head 142, an axial centering relief arranged to cooperate with a surface of complementary shape of the support surface head 141 and providing the function of gond 9 maintaining axial bearing alignment. The axial centering relief may be an upper appendage, that is to say an extension of the screw body 141 above the support surface 141, housed in an adjusted vertical passage of the second body 220, of the kind shown in FIG. in figure 2 . The hole 91 for the pin 151 is then formed in the screw 14.

In a dual manner, the axial centering relief may be a ring surrounding the support surface 141 to form a housing 149 open upwards in order to receive, to support and maintain its centering, a lower end of the upper section 94, or a endpiece thereof, such as the bearing bush 230, mounted in the second body 220, that is to say a coupling of the type shown for the section 92, but then without threading. In such an arrangement, the upper section 94, carried by the screw head 142, is therefore free of any need for rotation for adjustment. It can therefore be integral in rotation, or even in one piece, with the first or the second bearing elements 13, 23.

In another variant, the support bearing sleeve 130 is rotatably mounted and movable in axial translation with respect to the first body 120, and therefore in particular with respect to the first fastening elements 12, and one of the set of elements consisting of by the support bearing sleeve 130 and the first body 120, comprises, for this purpose, a thread, axial position adjustment, provided to cooperate with a complementary relief, integral with the other element of the assembly, for example a or many teeth or a complementary thread. It is therefore a screwing action that occurs at the level of the sleeve 130, that is to say without being deported at the lower section 92, which can be omitted or well preserved, but smooth, as centering tail, to ensure better support in the axial direction.

The substantially cylindrical free circumferential section of the sleeve 130 can then be striated to form an axial position adjusting wheel.

In short, in the above variants, the axial adjustment is effected through a kinematic chain in cascade, that is to say that the adjusting screw 14 does not directly regulate the bearings but regulates the axial position of the section 94 which, itself, carries the first bearing elements 13. The upper section 94, then free of own means of axial adjustment, is therefore driven by the adjusting screw 14, driving, functionally upstream of the kinematic chain, but the upper section 94 is also leading towards the downstream elements constituted by the first bearing elements 13. These are borne by the upper section 94 through a radial appendix such as the pin 151 or they comprise a partially blind axial hole open downwards to receive, bearing on a shoulder, radial or conical, in the periphery of its bottom, an end shoulder of the upper portion 94. Beyond the bottom of the hole, the axially portion The central section of the upper section 94, of restricted diameter, extends upwards to open the first bearing elements 13 and reach the second bearing elements 23, to ensure the desired centering.

The support bearing surface 131 and the support bearing surface 231 respectively comprise first and second ramps 132, 232, inclined on a horizontal plane, thus radial to the axial direction 10, provided to cooperate to cause a repulsion in axial translation of the second block 21 relative to the first block 11 during a pivoting of the second ramp 232, in a given direction, in an angular sector occupied by the first ramp 132. It is therefore unnecessary to pull or push the hinge 9 to adjust the axial position. In the case of the rotary bearing type bearing variant, the head of the bearing screw can bear, in simple axial support in a radial plane, a tip, non-circular radial section, movable only axially through a sliding guide in a housing of the same section, mouthpiece whose upper surface forms the ramp.

In this example, it is further provided possibilities of lateral adjustment, that is to say radial displacement of the axial direction 10. As explained at the beginning, the lateral adjustment elements could have been provided even in the absence axial position adjusting elements.

As shown in figure 3 , the first elements 12, for attachment to the frame 1, comprise a pair of complementary lateral adjustment elements, constituted by a first base 126, mounting on the frame 1, forming a complement or removable portion of the first body 120, coupled, here in an adjustable manner, to the first body 120, and therefore in particular to the first bearing elements 13. One of the elements of the pair of elements 120, 126, here the first body 120, comprises a 125DT serration having ribs , with vertically extending vertices, in the form of teeth 125D arranged in a range extending in a direction which, with respect to the axial direction 10, is transverse, and here substantially orthogonal that is to say horizontal and parallel to the bearing surface offered by the frame 1. The other element of the pair of elements 120, 126, so here the first base 126, comprises a relief 126DT, complementary to the indentation 125DT, to allow coupling between the two elements of the pair 120, 126 in a plurality of possible lateral disjoint positions possible offset, in association with elements 127 for maintaining the coupling in any chosen position, for example screws or fangs. The complementary relief 126DT may be limited to a tooth or, as here, be a serration with substantially the same number of teeth as the 125DT serration.

Similarly, the second elements 22, for attachment to the door 2, comprise a pair of complementary lateral adjustment elements constituted by the second body 220, hereby integrally coupled to the second bearing elements 23, and by a second removable base 226, for mounting on the door 2. One of the elements of the pair of elements 220, 226, precisely here the second body 220, comprises a serration 225DT having ribs, with vertices with directions of extensions vertical, globally referenced 225A ( Fig. 2 ), in the form of 225D teeth arranged in a range extending in a transverse direction, here substantially orthogonal, to the axial direction 10, that is to say horizontally and parallel to the coupling surface that the door 2 offers , namely a main face or a slice. The other element of the pair of elements 220, 226, thus here the second base 226, comprises a relief 226DT, complementary to the serration 225DT, to allow a coupling between the two elements of the pair of elements 220, 226. a plurality of relative disjoint positions possible lateral offset, in association with elements 227 for maintaining the coupling in any chosen position, for example screws or fangs. The complementary relief 226DT may be limited to a tooth or, as here, be a serration with substantially the same number of teeth as the serration 225DT. As shown in figure 2 , the indentation 225DT and the complementary relief 226DT are here distributed over two axially distant zones, to better ensure axial alignment.

The base 126, 226 comprises a nipple 126N, 226N for holding in position, intended to be introduced into the frame 1, respectively the door 2. Undequired screws are also provided.

Thus, the first and second bodies 120 and 220 can be temporarily decoupled from the respective first and second bases 126 and 226 to effect any desired lateral offset of a number of serration steps in the extension plane. of the respective complementary reliefs 126DT and 226DT, to then again mate the assembly. There is thus a plurality of disjoint positions offered for a lateral shift.

In this example, an adapter shim 228, of thickness offset of the second base 226, comprises an element 228A for fixing, or coupling, to the second base 226, precisely here a serration constituting a double of the serration 225DT of the second body 220 , or at least one equivalent element, with substantially the same functional characteristics as the latter, the number of teeth being different. The adapter shim 228 further comprises elements 228M for mounting and fixing, at a predetermined position, on the second body 220, here appendices position centering means associated with horizontal (non-drawn) fastening screws received in four open slots in a vertical wall and having horizontal extension directions to allow any desired lateral adjustment within the intended range. The lights 5 thus pass through the second base 226 to end in a threaded hole of the second body 220.

The same kind of shim can also be provided for the first base 126.

Alternatively, the complementary relief 226DT is arranged to also be moved in the extension direction 225A of each tooth 225D, which is then provided obliquely, preferably in a limited manner, with respect to the vertical axial direction of hinge, for thus having, for each of the disjoint lateral offset positions, another plurality of positions forming a continuation, which may be continuous, of both lateral and axial offset positions.

In such a case, the coupling between the second base 226 and the second body 220 can still be maintained by fixing screws, but with a wide head since the access holes 5, to the fixing holes, have had to be enlarged by height, in the axial direction 10. The resistance to vertical sliding between the opposing serrations 225DT, 226DT can for example be provided by friction, by an effective tightening of the fixing screws, or by undulations along the various teeth 225D, c that is to say by creating, in the first network constituted by the slightly inclined ribs on the vertical constituting the teeth 225D, another transverse network. In other words, and taking the example of the serrated relief 226DT, the valley bottoms, substantially vertical of the first network, would present a periodically varying depth, that is to say a notched profile intended to be coupled to peak areas, distributed with the same spatial periodicity, on top edges belonging to the 225DT serration opposite , to couple.

It can thus be provided that the zone comprising the serration 225DT actually comprises two such serrations, mutually crossed, perpendicularly or otherwise, with groove depths that are identical or different from one serration to the other. In short, it is thus formed a first regular network of pyramids whose peaks can be received in corresponding cavities of a second network, complementary reliefs in the form of cavities opposite rows and columns of the same steps as their counterparts of the first network. The cavities may be mutually disjoint, that is to say each lead to a common flat surface of the second network, or lead to the bottom of a valley, as explained above.

If then the valleys oriented in one of the two directions, for example "column", have a depth greater than those which are transverse to them, the tops of the pyramids can thus be slid from one cavity to another by keeping them substantially at the bottom of the valley "column", so without risk of parasitic shift in an unwanted direction by an involuntary jump of each pyramid to a valley "column" next to the one where it must move. On the other hand, if each pyramid is to pass to another valley of the complementary relief, in order to make a shift in the "line" direction, the pyramids and the complementary relief zone, with cavities, will be mutually slightly recessed so that the peaks of the pyramids can pass in the "transverse" passes that the network "line" has created in the network "column". The "transverse" necks above then provide guidance in the "line" direction, that is to say that each pyramid will remain at its line then associated, and can again move in the "column" direction that 'after leaving the "transverse" pass and entering a new "column" valley. Note that the two areas to be coupled, serration and complementary relief, may have different extents, insofar as the desired strength of the coupling is ensured. It can also be expected that one of the two zones above can be coupled to the other with partial overflow on a marginal area, non-functional thereof, to the extent that this marginal area does not have relief likely to hinder the coupling.

The Figures 4 and 5 illustrate three adjustment positions relating to three respective types of adjustment, each position being extreme in the respective adjustment range. Thus, the hinge 9 is raised 5 mm from the average position according to the figure 2 , and, independently, on the figure 5 the 125DT serration of the first body 120 is shifted 5 mm to the right with respect to the first base 126, and, independently, the serration of the adapter shim 228, which is a duplicate of the 225DT body serration, is shifted by 5 mm down. Compared with average positions according to figures 2 and 3 we can deduce, symmetrically, second extreme positions, opposite to those drawn.
