Abstract

A first ring 4 is mounted on the axis 3 of the hinge and it carries a second ring 7 which has a first thread 9 which is screwed with a thread 6 of the first ring as well as a second thread 12 with a pitch opposite to that of the first thread 9 and screwed with an external thread 15 of a third ring 14 mounted to slide axially, without being able to turn, on the first ring 14, which makes it possible to easily adjust the distance between the parts 1 and 2 of the hinge.

Description

The subject of the invention is a device which can be incorporated into a

  hinge during manufacture, or attached to an existing hinge, to allow

  vertically adjust the distance between the coo-

  perants of this hinge. A palm is made up of two pieces that have

  each a fixing lug for their respective fixing

  on the one hand to a panel movable by pivoting, on the other hand to a fixed frame. These two pieces have, in addition, each

  1U a blind hole and an axis is engaged in The two bor-

  Genes put in extension of each other. The extreme face which surrounds the blind hole of the upper part rests on

  the extreme face which surrounds the blind hole of the lower part

  better. These two faces slide over each other when the movable panel pivots around the passing geometric axis

  by the two blind holes and by the axis that these holes contain

nent.

  With conventional hinges when a sag

  ment or a downward deformation of the panel carried by the hinges has occurred, it is necessary to bring the end face of the lower part of each of the hinges carrying this panel to a higher level. Commonly, this change is made by placing one or more washers around the axis of each hinge, between the end face

  upper part The lower part and the lower end face

upper room.

  This procedure requires dismantling the pan-

  neau, or to unhinge it, separating the pieces from each

  hinge to access the axis which remains in the lower part

  fixed to the fixed frame and to be able to put on this

  axis one or more washers having, alone or together

  ble, the desired thickness equal to the desired lifting of the movable panel. Then, replace the panel in its place by simultaneously threading the upper parts of the

  hinges on the axes remained in the lower parts.

  Such an operation takes time and is sometimes not easy to perform by a single person, in particular

  when the movable panel is heavy or large.

  The main object of the invention is to provide a device which can be fitted to a conventional hinge and which makes it possible to precisely adjust the level of the end face of the support of a movable panel by this hinge without it

  be necessary to dismantle this panel.

  Another object of the invention is to achieve a device of the type defined above designed in such a way that it can just as well be incorporated into a hinge during manufacture as it is attached to a palm.

  existing already in use.

  The above goals are achieved with a device

  for hinges having a lower part, an upper part

  rieure, an axis engaged at the same time in a blind hole of the

  lower part and in a blind hole in the upper part

  this device comprising, in accordance with the invention, a first ring having a through hole which can contain the axis of the hinge and an external thread on its external lateral face, a second ring with internal thread screwed onto the first ring , a means of blocking in

  rotation of the first ring on the second ring, this

  seems of the two rings being placed around the axis between the

  upper part and the lower part of the hinge.

  Preferably, there is also a means of immobilizing

  reading of the first ring on the hinge axis.

  According to one embodiment of the invention, the first ring has on its external lateral face a first zone of a determined diameter which carries the external thread and a second zone, distinct in the axial direction from the

  first zone, having a size in transverse direction inferior

  smaller than said diameter with a non-revolution profile and a smooth surface in the longitudinal direction; a third ring

  is mounted on the second zone of the first ring for

  see sliding along said smooth surface while being immobilized in rotation relative to this first ring, this third ring having on its external face an external thread to which corresponds on the internal face of the second ring a second complementary thread; these threads are screwed together and are in the opposite direction to the direction of the threads which cooperate between The first ring

and the second ring.

  With this embodiment, blocking the

  second ring on the first ring is produced by the enga-

  the latter with the third ring which is itself

  even immobilized in rotation relative to the first ring.

  According to a variant of this embodiment, the first ring is chosen with an internal diameter which is slightly less than the diameter of the axis so that this first ring is fitted by force fitting on

said axis.

  On some hinges the axis is not immobilized

  dried in one of the two rooms, but it is left free in rotation and translation. In this case, the first ring of the device of the invention is immobilized in rotation at

  using a pawn partially inserted into a parallel hole

  lele to the axis drilled in the end face of this first ring and in a similar hole drilled in the face of the

  piece on which this first ring rests.

  We will now give a description of several

  exemplary embodiments of the invention, without limiting intention and without excluding any variant. Reference will be made to the accompanying drawings in which: FIG. 1 is a partial section view passing through the geometric axis of rotation of the two parts of a hinge fitted with a device of the invention according to its simplest aspect, - Figure 2 is a partial view similar to Figure 1 of a second more improved embodiment 4. of the device of the invention, - Figure 3 is a view along arrow F of Figure 2, - Figure 4 is a partial view similar to FIG. 2 of a third embodiment of the invention, FIG. 5 is a sectional view passing through

  the axis of a ring which is part of the device of the fig-

  re 4, - Figures 6 and 7 are views from the outside of a hinge fitted with a device according to Figures 2

  or 4 respectively shown at two adjustment positions.

  The hinge shown in Figure 1 is of a completely common type consisting of two identical parts 1,2 which, after assembly, rest on each other containing an axis 3 by which a relative pivoting of the parts 1 and 2 is made possible. The upper part 2 is fixed to a panel (this word designates here a door, a window, a gate, etc.) which is pivotally movable; as we know it is often necessary to modify the position of this panel in the direction of lifting relative to the

piece 1 fixed to a fixed frame.

  In its simplest aspect the device of

  the invention comprises a first ring 4 having a central hole

  tral 5 to the diameter chosen to be able to be threaded on

  axis 3 and a threaded external lateral face 6. A two

  xth ring 7 also has a central hole 8 through which it can be threaded on the axis 3 and an inner side face

  threaded 9 by which it screws onto the first ring 4.

  By unscrewing the second ring 7 relative to the first ring 4 it is modified with precision and with ease the total height of the two assembled rings 4,7. It suffices to lift the movable panel (not shown) to which the part 2 is fixed, without dismantling it, in order to be able to rotate the

  two rings 4,7 relative to each other.

  So that the setting, i.e. the relative position

  tive given to the two rings 4,7 keeps over time, during the alternating pivotings of the movable panel, it is provided as a means of immobilizing the second ring 7 on the first ring 4 a radial screw 10 such as a needle screw with a slot at the end opposite to the pointed end which is mounted on the second ring 7, this screw 10

  screwing into a corresponding threaded hole until

counter the first ring 4.

  It is also desirable that the first ring 4

  can be immobilized in rotation at least during the

  execution of an adjustment operation. Several means can be adopted, either a radial hole provided in this first ring 4 to be able to introduce the end of a tool there, or a threaded radial hole in which a second needle screw can be screwed coming to meet the axis 3, or

  a central hole 5 chosen so that the first ring 4 becomes

  force handle on axis 3. This last solution is the simplest, mainly when axis 5 is itself immobilized by a force fitting, or by another means, in a room, generally the lower part 1,

from the hinge.

  The embodiment described above allows adjustment only along the axial length of the threads 6.9

of the two rings.

  In the embodiment illustrated by Figures 2 to 7 o the elements identical to those of Figure 1 are designated by the same reference numerals, the first ring 4 has on its outer side face a first zone which carries the thread 6 , at a determined diameter, and a second zone 11 distinct in axial direction from the first threaded zone 6. This second zone 11 has a

  size in transverse direction less than that of the first

  mier zone and, moreover, it has a profile which is not of revolution, octagonal for example as one can see it on

  Figure 3, with a smooth surface in the longitudinal direction.

262384.2

  The second ring 7 has an inner lateral face which presents in longitudinal direction the thread 9 which is screwed

  on thread 6 of the first ring and a second thread

  stage 12 whose pitch is in the opposite direction to the pitch of thread 9.

  The two parts with opposite threads 9,12 have lengths

  identical and are separated by a central recess 13.

  There exists in this example of realization a three-

  fifth ring 14 which has an external lateral face provided

  a thread 15 capable of being screwed in with the second thread-

  stage 12 of the second ring 7. The inner lateral face of the third ring 14 is smooth and has the same profile

  than that of the second zone 11 of the first ring 4.

  Thus, the third ring mounts Free to slide on The second zone 11 of the first ring 4 at the same time as

  its external thread 15 is engaged with the second file-

  corresponding inner stage 12 of the second ring 7. At the same time, the first thread 9 of this second ring 7

  is engaged with the thread 6 of the first ring 4.

  As the pitches of the two threads 9.12 sQnt identi-

  ques but in opposite directions, when we unscrew the second ring 7 relative to the first ring 4 to raise it, that is to say to lift the upper part 2 relative to the lower part 1, a movement of unscrewing also occurs between threads 12 and 15 of the second ring 7 and the third ring 14. Since the latter is immobilized in rotation by its inner lateral face, this third ring 14 moves in translation and it also rises with respect to the second ring 7. The total lifting movement of the upper part 2 relative to the lower part 1 of the hinge is therefore the sum of the thread pitches 6.9 on the one hand and 12.15 on the other hand, for

  each rotation of the second ring 7.

  FIG. 2 shows the device in its state of maximum lifting of the upper part 2 relative to the lower part 1; we see that when moving towards the

262384?

  top by unscrewing the second ring 7 is added the displacement

  cement upwards of the third ring 14 relative to

the second ring 7.

  Figure 4 is made up of two different halves

  your. The left half when looking at this figure shows the device in its initial state, at its lowest height dimension. Figure 6 shows the external appearance of the device in this state. The right half of Figure 4 shows the device in its final state, at its largest height dimension, as in Figure 2. Figure 7 shows

  the external appearance of the device in its final state.

  The adjustment movement described above requires that the first ring 4 be immobilized in rotation. In this regard, any of the means mentioned above in

  About the example of Figure 1 can be used.

  In the case of FIG. 2, it is assumed that the axis 3 is itself immobilized by a force fitting in the lower part 1. The first ring 4 has a diameter

  interior determined to allow fitting by sleeve

force on axis 3.

  Note that this assembly can be done on a poor

  melle new and, as well, on a hinge already in service.

  The device of the invention can therefore be used on all

The existing paumetles.

  In the case of Figure 4, it is assumed that the axis 3 is not immobilized in rotation in the parts 1

  or 2 from the hinge. A hole 16 is drilled in the extreme face

  me lower of the first ring 4 and a pawn 17 is intro-

  force down over part of its length in this hole 16.

  When the device is mounted on a hinge, a hole 18 with a diameter preferably greater than that of the pin 16 is drilled in the end face of the lower part 1 on which the first ring 4 rests and the projecting part of the pin 16 is introduced into this hole, which prevents the

rotation of the first ring 4.

  FIG. 3 shows that the third ring 14 is immobilized in rotation relative to the first ring 4

  thanks to the non-revolution profile of this ring 4. The third

  fifth ring 14 has the necessary complementary profile only in its lower end portion 14A. On the rest of

  its length, the third ring 14 has an internal widening

  laughing 14B which shows an internal shoulder 19.

  After assembly of the third ring 14 with the first ring 4, the upper extreme edge of this first ring 4 is deformed in several places, for example by a few punches at the points 20 (FIG. 3) so that the deformations 21 are in relief with respect to the shoulder 14 and that the third ring 14 is no longer removable from the

  first ring 4 by sliding in the axial direction.

  The production of the first ring 4 described with reference to FIGS. 2 and 3 requires giving this ring two different configurations in the direction of its length and giving at least part of the inner face of the third ring 14 a complementary configuration

not of revolution.

  The right half of Figure 4 and Figure 5 illustrate a variant that provides the same result in

  leaving a cylindrical configuration to the rings 4 and 14.

  A longitudinal hole 22 parallel to the axis 3 is drilled from the lower end face of the first ring 4, so as to be located partly on the one hand in this first ring 4, on the other hand in the third

  ring 14 in the area where these two rings have cy-

  lindriques in contact after their assembly, then a

  cylindrical pin 23 is inserted into the longitu-

  dinal 22. By this assembly, analogous to a keying, the three-

  fifth ring 14 is immobilized in rotation relative to

the first ring 4.

  The invention also relates to any hinge of any type which is equipped with a device for adjusting

  vertical direction according to the invention.
