Abstract

The hinge comprises a cartridge placed in the fixed and movable barrels. The cartridge comprises a radially deformable cylinder body (8) having an internal cavity open at one end of the body. The other end of the body comprises a bottom (11) with an axial tapped hole. A screw (12) is housed axially in the cavity and its threaded end (15) engages the tapped hole and its head (13) is located at the cavity inlet. Elastomer sleeves (18) and spacers (16) are alternately threaded on the screw shank (14) and fill the cavity. The clamping screw causes compression of the sleeves and an expansion of the cylindrical body peripheral wall (9). The sleeves are placed opposite the movable barrels. In addition there are axial ribs (19a,19b) on the body to immobilize it in the fixed barrels.

Description

L'invention concerne le domaine des charnières comportant au moins un charnon mobile placé entre deux charnons fixes, une broche passant par tous les charnons et des moyens pour exercer un couple de freinage réglable sur le charnon mobile.The invention relates to the field of hinges comprising at minus a movable knuckle placed between two fixed knuckles, a spindle going through all the knuckles and ways to exercise a couple of adjustable braking on the movable knuckle.

De telles charnières sont utilisées lorsque l'ouvrant doit rester dans une position fixe après son ouverture. Il en est ainsi par exemple pour les portes des armoires techniques au cours de la maintenance, et pour les écrans plats des ordinateurs portables qui doivent conserver une position verticale ou légèrement inclinée en cours d'utilisation.Such hinges are used when the opening must remain in a fixed position after opening. This is so for example for the doors of technical cabinets during maintenance, and for flat screens of laptops which must keep a upright or slightly tilted position during use.

FR A 2 613 002 décrit un frein de charnière notamment pour ouvrant de hublot dans lequel il est prévu entre les portées cylindriques des deux pentures et la broche de la charnière, un manchon en une matière élastomérique semi-rigide, et on met en appui contre les extrémités opposées du manchon deux éléments cylindriques susceptibles de s'engager dans les portées cylindriques des deux pentures et enfilés sur la broche, cette dernière comportant une tête de broche et une extrémité filetée coopérant avec un écrou de serrage pour comprimer le manchon en élastomère. Cet écrou sert à la fois à la fixation de la broche et à la compression du manchon élastomère. Dans cette disposition, la paroi périphérique du manchon en élastomère coopère directement avec les parois cylindriques du charnon fixe et du charnon mobile. Le manchon est ainsi soumis à des couples de torsion qui peuvent être préjudiciables au maintien de son intégrité. En outre, la tête de vis et l'écrou sont en appui sur les faces extrêmes des charnons, ce qui nuit à l'aspect esthétique de l'ensemble, et peut entraíner un desserrage de l'écrou.FR A 2 613 002 describes a hinge brake in particular for window opening in which it is provided between the cylindrical seats of the two hinges and the hinge pin, a sleeve in one semi-rigid elastomeric material, and is pressed against opposite ends of the sleeve two cylindrical elements likely to engage in the cylindrical bearings of the two hinges and threaded on the spindle, the latter comprising a spindle and a threaded end cooperating with a clamping nut for compress the elastomer sleeve. This nut is used for both fixing of the spindle and compression of the elastomeric sleeve. In this arrangement, the peripheral wall of the elastomer sleeve cooperates directly with the cylindrical walls of the fixed knuckle and knuckle mobile. The sleeve is thus subjected to torques which may be detrimental to the maintenance of its integrity. In addition, the head screw and nut are supported on the end faces of the knuckles, this which harms the aesthetic appearance of the whole, and can lead to a loosening the nut.

Partant de cet état de la technique, l'invention s'est donnée pour but de proposer une charnière équipée d'un frein, dans lequel le manchon en matière élastomérique semi-rigide est uniquement soumis à des efforts de compression axiale.Starting from this state of the art, the invention is given aim of proposing a hinge fitted with a brake, in which the sleeve of semi-rigid elastomeric material is only subjected to axial compression forces.

Un deuxième but de l'invention est de proposer une cartouche formant broche pour solidariser les charnons, qui soit facile à monter et démonter et qui inclut les moyens de freinage.A second object of the invention is to propose a cartridge forming a pin to secure the knuckles, which is easy to assemble and disassemble and which includes the braking means.

Un autre but de l'invention est de proposer un dispositif de freinage de charnière qui soit facilement réglable. Another object of the invention is to propose a device for hinge brake which is easily adjustable.

La charnière selon l'invention est caractérisée par le fait que la broche est constituée d'un corps de cylindre déformable radialement qui a une cavité interne cylindrique débouchant à l'une des extrémités dudit corps et qui présente à l'autre extrémité un fond dans lequel est ménagé un orifice axial taraudé dont le diamètre est inférieur au diamètre de la cavité, ledit corps de cylindre présentant en outre des moyens pour l'immobiliser en rotation par rapport à au moins l'un desdits charnons fixes, et par le fait que les moyens pour exercer un couple de freinage comportent une vis dont la tête loge dans l'entrée de la cavité et dont le fût est terminé par un filetage coopérant avec l'orifice axial taraudé dudit corps de cylindre, des manchons en matière élastomérique semi-rigide et des entretoises annulaires rigides enfilés en alternance sur le fût de la vis et dimensionnés de manière à remplir l'espace annulaire de la cavité qui entoure le fût, les manchons en matière élastomérique étant disposés en regard des charnons mobiles afin qu'un serrage de la vis provoque une compression desdits manchons et une expansion radiale des portions de paroi cylindriques dudit corps situées dans les charnons mobiles.The hinge according to the invention is characterized in that the spindle consists of a radially deformable cylinder body which has a cylindrical internal cavity opening at one end of said body and which has at the other end a bottom in which is formed a threaded axial hole whose diameter is less than the diameter of the cavity, said cylinder body further having means for immobilize it in rotation relative to at least one of said knuckles fixed, and by the fact that the means for exerting a braking torque have a screw whose head is housed in the entrance of the cavity and whose barrel is terminated by a thread cooperating with the threaded axial orifice of said cylinder body, sleeves of semi-rigid elastomeric material and rigid annular spacers threaded alternately on the barrel of the screw and dimensioned so as to fill the annular space of the cavity which surrounds the barrel, the sleeves made of elastomeric material being arranged in look at the movable knuckles so that tightening the screw causes a compression of said sleeves and a radial expansion of the portions of cylindrical wall of said body located in the movable knuckles.

Avantageusement, les moyens pour immobiliser en rotation le corps de cylindre par rapport à un charnon fixe comportent un ergot radial formé sur la paroi périphérique du corps de cylindre et une rainure axiale formée dans la paroi interne dudit charnon pour recevoir ledit ergot.Advantageously, the means for immobilizing in rotation the cylinder body relative to a fixed knuckle have a radial lug formed on the peripheral wall of the cylinder body and an axial groove formed in the internal wall of said knuckle to receive said lug.

De préférence, l'ergot est constitué d'une nervure axiale s'étendant sensiblement sur toute l'étendue du charnon fixe correspondant.Preferably, the lug consists of an axial rib extending substantially over the entire extent of the fixed knuckle corresponding.

Selon une autre caractéristique de la charnière proposée, le corps de cylindre comporte un ergot en regard de chaque charnon fixe, ces charnons fixes comportant des rainures axiales alignées, et les charnons mobiles présentent chacun une nervure axiale susceptible d'être alignée avec les nervures des charnons fixes dans une position déterminée de montage et démontage de la broche.According to another characteristic of the proposed hinge, the cylinder body has a lug opposite each fixed knuckle, these fixed knuckles having aligned axial grooves, and the mobile knuckles each have an axial rib capable of being aligned with the ribs of the fixed knuckles in a determined position for mounting and dismounting the spindle.

Avec cette dernière caractéristique, la broche ne peut être montée ou démontée que lorsque toutes les nervures des charnons fixes ou mobiles sont alignées.With this last characteristic, the spindle cannot be assembled or disassembled only when all the ribs of the fixed knuckles or mobiles are aligned.

La cartouche, selon l'invention, destinée à freiner une charnière ayant au moins un charnon mobile placé entre deux charnons fixes est caractérisée par le fait qu'elle comporte :

  • un corps de cylindre déformable radialement destiné à être placé dans lesdits charnons, ledit corps de cylindre ayant une cavité interne débouchant à l'une des extrémités dudit corps et présentant à l'autre extrémité un fond dans lequel est ménagé un orifice axial taraudé dont le diamètre est inférieur au diamètre de la cavité,
  • une vis dont la tête loge dans l'entrée de la cavité et dont le fût est terminé par un filetage coopérant avec l'orifice axial taraudé dudit corps de cylindre,
  • des manchons en matière élastomérique semi-rigide et des entretoises annulaires rigides enfilés en alternance sur le fût de la vis et dimensionnés de manière à remplir l'espace annulaire de la cavité, qui entoure le fût.
    • The cartridge, according to the invention, intended to brake a hinge having at least one movable knuckle placed between two fixed knuckles is characterized in that it comprises:
  • a radially deformable cylinder body intended to be placed in said knuckles, said cylinder body having an internal cavity opening at one end of said body and having at the other end a bottom in which is formed a threaded axial orifice whose diameter is less than the diameter of the cavity,
  • a screw whose head is housed in the entrance of the cavity and whose barrel is terminated by a thread cooperating with the tapped axial orifice of said cylinder body,
  • sleeves of semi-rigid elastomeric material and rigid annular spacers threaded alternately on the barrel of the screw and dimensioned so as to fill the annular space of the cavity, which surrounds the barrel.

    • De préférence, le corps de cylindre comporte en outre des moyens pour l'immobiliser en rotation par rapport à au moins l'un des charnons fixes.Preferably, the cylinder body further comprises means for immobilizing it in rotation with respect to at least one of the fixed knuckles.

    Avantageusement, les moyens d'immobilisation comportent au moins un ergot radial formé sur la paroi périphérique du corps de cylindre.Advantageously, the immobilization means comprise at minus a radial lug formed on the peripheral wall of the cylinder body.

    De préférence, l'ergot est constitué d'une nervure axiale.Preferably, the lug consists of an axial rib.

    D'autres avantages et caractéristiques de l'invention ressortiront de la lecture de la description suivante faite à titre d'exemple et en référence aux dessins annexés, dans lesquels :

  • la figure 6 est une coupe selon un plan passant par son axe d'une broche reliant trois charnons fixes et deux charnons mobiles d'une charnière.
    • Other advantages and characteristics of the invention will emerge from reading the following description given by way of example and with reference to the appended drawings, in which:
  • Figure 1 is a top view of a hinge according to the invention arranged flat;
  • Figure 2 is a side view of the hinge of Figure;
  • Figure 3 is a perspective view of the same hinge which rises one of the ends of the spindle;

  • Figure 6 is a section along a plane passing through its axis of a pin connecting three fixed knuckles and two movable knuckles of a hinge.

    • Les figures 1 à 4 montrent une charnière 1 comportant deux paumelles 2a, 2b. Figures 1 to 4 show a hinge 1 comprising two hinges 2a, 2b.

    La paumelle 2a, dite fixe, comporte deux charnons fixes 3a et 3b, et la paumelle 2b, dite mobile, comporte un charnon mobile 4a disposé entre les deux charnons 3a et 3b. Une broche 5 montrée en coupe sur la figure 5 est disposée dans les orifices cylindriques alignés des trois charnons 3a, 3b et 4a. Ainsi que cela se voit sur les dessins, les charnons fixes 3a et 3b présentent des rainures 6a et 6b alignées parallèles à l'axe 7 de la charnière 1.The hinge 2a, called fixed, comprises two fixed knuckles 3a and 3b, and the hinge 2b, called mobile, comprises a mobile knuckle 4a disposed between the two knuckles 3a and 3b. A pin 5 shown in section in Figure 5 is arranged in the aligned cylindrical holes of the three knuckles 3a, 3b and 4a. As can be seen in the drawings, the fixed knuckles 3a and 3b have aligned grooves 6a and 6b parallel to the axis 7 of the hinge 1.

    Le charnon mobile 4a comporte également une rainure 6c qui, dans une position angulaire déterminée des paumelles 2a et 2b, se trouve dans l'alignement des rainures 6a et 6b.The movable knuckle 4a also has a groove 6c which, in a determined angular position of the hinges 2a and 2b, there is in alignment with the grooves 6a and 6b.

    La broche 5 comporte un corps de cylindre 8 ayant une paroi périphérique cylindrique 9 déformable radialement qui délimite une cavité interne 10 cylindrique d'axe 7 débouchant sur une face d'extrémité du corps 8 et un fond 11 dans lequel est ménagé axialement un orifice axial taraudé ayant un diamètre inférieur au diamètre de la cavité 10. L'épaisseur du fond 11 est légèrement plus grande que la hauteur d'un charnon fixe 3a, 3b.The spindle 5 comprises a cylinder body 8 having a wall radially deformable cylindrical device 9 which delimits a cavity internal 10 cylindrical with axis 7 opening onto an end face of the body 8 and a bottom 11 in which an axial orifice is provided axially threaded with a diameter less than the diameter of the cavity 10. The thickness of the bottom 11 is slightly greater than the height of a fixed knuckle 3a, 3b.

    Une vis 12, comportant une tête de vis 13 et un fût 14 dont la partie d'extrémité 15 est filetée s'étend axialement dans la cavité 10. La tête 13 de la vis 12 est disposée à l'entrée de la cavité 10, tandis que sa partie filetée 15 coopère avec l'orifice taraudé du fond 11.A screw 12, comprising a screw head 13 and a barrel 14, the end portion 15 is threaded extends axially in the cavity 10. The head 13 of the screw 12 is disposed at the entrance to the cavity 10, while its threaded part 15 cooperates with the tapped hole in the bottom 11.

    Sur le fût 14 est enfilé, d'une part, un poussoir 16 en appui contre la face interne de la tête de vis 13 et présentant une collerette 17 entourant la tête de vis 13, et d'autre part un manchon 18 interposé entre le poussoir 16 et le fond 11.On the barrel 14 is threaded, on the one hand, a pusher 16 in support against the internal face of the screw head 13 and having a flange 17 surrounding the screw head 13, and on the other hand a sleeve 18 interposed between the pusher 16 and the bottom 11.

    Le poussoir 16 et le manchon 18 occupent au repos la totalité de l'espace annulaire entourant le fût 14 et délimité par la paroi périphérique cylindrique 9. La longueur totale du poussoir 16, réalisé en un matériau rigide indéformable, est légèrement supérieure à la hauteur du charnon fixe 3a.The pusher 16 and the sleeve 18 occupy the whole at rest of the annular space surrounding the barrel 14 and delimited by the peripheral wall cylindrical 9. The total length of the pusher 16, made in one rigid non-deformable material, is slightly greater than the height of the fixed knuckle 3a.

    Le corps de cylindre 8 comporte en outre sur sa paroi périphérique externe, deux nervures axiales alignées 19a et 19b destinées à loger dans les rainures 6a, 6b des charnons fixes 3a et 3b. Pour placer la broche 8 dans les yeux des charnons 3a, 4b et 4a, on l'introduit par l'une des extrémités libres de ces charnons, on fait coulisser la nervure 19a par exemple dans la rainure 6b, puis la rainure 6c mise en alignement avec les rainures 6a et 6b, puis la rainure 6a. La nervure 19b est alors positionnée dans la rainure 6b.The cylinder body 8 further comprises on its peripheral wall external, two aligned axial ribs 19a and 19b intended to lodge in the grooves 6a, 6b of the fixed knuckles 3a and 3b. To place the pin 8 in the eyes of knuckles 3a, 4b and 4a, we introduce it by one free ends of these knuckles, the rib 19a is made to slide by example in groove 6b, then groove 6c aligned with the grooves 6a and 6b, then the groove 6a. The rib 19b is then positioned in the groove 6b.

    Lorsqu'on fait ensuite pivoter la paumelle 2b autour de la broche 8, cette dernière est immobilisée en rotation et axialement sur les charnons fixes 3a et 3b.When the hinge 2b is then pivoted around the spindle 8, the latter is immobilized in rotation and axially on the fixed knuckles 3a and 3b.

    Le manchon 18 est réalisé en une matière élastomérique semi-rigide.The sleeve 18 is made of a semi-rigid elastomeric material.

    La tête de vis 13 comporte sur sa face externe une empreinte 20 destinée à coopérer avec un outil approprié pour permettre le serrage de la vis 12. L'empreinte peut être réalisée sous la forme d'un trou à 6 pans par exemple.The screw head 13 has on its external face a impression 20 intended to cooperate with an appropriate tool to allow tightening screw 12. The impression can be made in the form of a Hexagon hole for example.

    Le serrage de la vis 12 provoque une compression axiale du manchon 18, et une expansion radiale de la portion de paroi cylindrique 9a entourant le manchon 18. Du fait des dimensions données au fond 11 et au poussoir 16, le manchon 18, hors contraintes, est disposé en regard du charnon fixe 4a. La longueur du manchon 18 est sensiblement inférieure à la hauteur du charnon mobile 4a. Le diamètre du corps de cylindre 8 est au plus égal au diamètre des yeux des charnons 3a, 3b et 4a. Lorsque la vis 12 est desserrée, la broche 8 est immobilisée sur les charnons fixes 3a et 3b, et le charnon mobile 4a peut pivoter autour de la broche 8 sans frottements. Dans cette situation de non-serrage de la vis 12, il est possible de monter la broche 5 sur les charnons ainsi que cela a été expliqué ci-dessus et de la démonter par le cheminement inverse, à condition d'aligner préalablement la rainure 6c avec les rainures 6a et 6b.Tightening the screw 12 causes axial compression of the sleeve 18, and a radial expansion of the cylindrical wall portion 9a surrounding the sleeve 18. Due to the dimensions given to the bottom 11 and the pusher 16, the sleeve 18, without constraints, is arranged opposite the fixed knuckle 4a. The length of the sleeve 18 is substantially less than the height of the movable knuckle 4a. The diameter of the cylinder body 8 is at most equal to the diameter of the eyes of the knuckles 3a, 3b and 4a. When the screw 12 is loosened, the pin 8 is immobilized on the fixed knuckles 3a and 3b, and the mobile knuckle 4a can rotate around pin 8 without friction. In this situation of non-tightening of screw 12, it is possible to mount pin 5 on the knuckles together as has been explained above and disassemble it by the reverse path, provided that groove 6c is aligned beforehand with grooves 6a and 6b.

    En revanche, lorsque la vis 12 est serrée, le manchon 18 est comprimé axialement et la portion de paroi 9a s'expanse radialement et appuie positivement contre la paroi interne cylindrique du charnon mobile 4a, ce qui crée un couple de freinage d'autant plus grand que le serrage est fort. Ce couple de freinage s'oppose à la rotation du charnon mobile 4a par rapport aux charnons fixes 3a et 3b.On the other hand, when the screw 12 is tightened, the sleeve 18 is axially compressed and the wall portion 9a expands radially and presses positively against the cylindrical inner wall of the knuckle mobile 4a, which creates a braking torque all the greater as the tightening is strong. This braking torque is opposed to the rotation of the knuckle movable 4a relative to the fixed knuckles 3a and 3b.

    L'épaisseur de la paroi périphérique 9 et le matériau constitutif du corps de cylindre 8 sont choisis de telle manière que la portion de paroi 9a puisse se déformer radialement, tout en assurant le freinage et l'intégrité de la broche 8. Les paumelles 2a et 2b peuvent être réalisées en métal ou en un matériau plastique rigide. Il en est de même du corps de cylindre 8.The thickness of the peripheral wall 9 and the constituent material of the cylinder body 8 are chosen such that the wall portion 9a can deform radially, while ensuring braking and the integrity of the spindle 8. The hinges 2a and 2b can be produced made of metal or a rigid plastic material. It is the same with the body cylinder 8.

    Dans l'exemple décrit ci-dessus et montré sur les figures 1 à 5, la paumelle mobile 2b ne comporte qu'un seul charnon mobile 4a interposé entre deux charnons fixes 3a et 3b de la paumelle fixe 2a.In the example described above and shown in Figures 1 to 5, the movable hinge 2b has only one movable knuckle 4a interposed between two fixed knuckles 3a and 3b of the fixed hinge 2a.

    La figure 6 montre un exemple de charnière 1 dans laquelle la paumelle fixe 2a qui présente trois charnons fixes référencés 3a, 3b et 3c et la paumelle mobile 2b comportent deux charnons mobiles référencés 4a et 4b. Le charnon mobile 4a est interposé entre les charnons fixes 3a et 3b, et le charnon mobile 4b est interposé entre les charnons fixes 3b et 3c.Figure 6 shows an example of hinge 1 in which the fixed hinge 2a which has three fixed knuckles referenced 3a, 3b and 3c and the mobile hinge 2b comprise two mobile knuckles referenced 4a and 4b. The movable knuckle 4a is interposed between the fixed knuckles 3a and 3b, and the mobile knuckle 4b is interposed between the fixed knuckles 3b and 3c.

    La vis 12 est identique à la vis décrite dans le mode de réalisation précédent. Il en est de même du poussoir 16. Ainsi qu'on le voit sur la figure 6, une entretoise rigide 21 enfilée sur le fût 12 est interposée entre deux manchons 18a et 18b en matière élastomérique.The screw 12 is identical to the screw described in the embodiment previous. The same applies to push-button 16. As can be seen on the Figure 6, a rigid spacer 21 threaded on the barrel 12 is interposed between two sleeves 18a and 18b made of elastomeric material.

    L'entretoise 21 est disposée en regard du charnon fixe intermédiaire 3b.The spacer 21 is arranged opposite the intermediate fixed knuckle 3b.

    Le serrage de la vis 12 provoque ici la compression des deux manchons 18a et 18b et l'expansion des portions de paroi cylindriques 9a, 9b disposées en regard des charnons mobiles 4a et 4b. Le corps de cylindre 8 ne comporte qu'une seule nervure axiale 19a.The tightening of the screw 12 here causes the compression of the two sleeves 18a and 18b and the expansion of the cylindrical wall portions 9a, 9b arranged opposite the mobile knuckles 4a and 4b. The body of cylinder 8 has only one axial rib 19a.
