The sleeve comprises a truncated cylinder portion and a truncated section centred on the connecting rod axis. The brake casing has a cavity with a cylindrical section portion and a truncated section which houses the sleeve.

Description

La présente invention concerne un dispositif de freinage de tringle déplacée en translation par un organe de manoeuvre, notamment lors de l'ouverture et de la fermeture d'un ouvrant.The present invention relates to a device for rod braking displaced in translation by a operating device, especially during opening and closing an opening.

Elle concerne également un ouvrant coulissant par levage équipé d'un tel dispositif.It also relates to a sliding leaf by lifting equipped with such a device.

De manière connue, un ouvrant, tel que porte, fenêtre, porte-fenêtre ou analogue, est monté sur un dormant et comprend une ferrure, telle que crémone, crémone-serrure, commandant, par l'intermédiaire d'une ou plusieurs tringles, des dispositifs de verrouillage de l'ouvrant (galet, pêne,...) coopérant avec des gâches du dormant.In a known manner, an opening, such as a door, window, French window or the like, is mounted on a dormant and includes a fitting, such as a cremone bolt, lock-bolt, commander, via a or more rods, locking devices opening (roller, bolt, ...) cooperating with strikes of the dormant.

Il est connu, notamment dans les ouvrants coulissants, oscillants ou oscillo-battants, d'équiper l'ouvrant de dispositifs annexes de manoeuvre de l'ouvrant tels que des dispositifs de levage de l'ouvrant dans son plan vertical, des dispositifs de compas permettant l'ouverture en soufflet de l'ouvrant, pivotant autour d'une traverse, ou encore des dispositifs de décalage de l'ouvrant parallèlement à sa position de fermeture, dans un plan horizontal.It is known, especially in opening sliding, oscillating or tilt-and-turn, to equip the opening of auxiliary devices for maneuvering opening it such as lifting devices opening it in its vertical plane, compass allowing the bellows opening of the opening, pivoting around a cross member, or sash shifting devices parallel to its closed position, in a horizontal plane.

Traditionnellement, ces dispositifs de manoeuvre de l'ouvrant sont actionnés également par les tringles montées sur la ferrure de l'ouvrant, éventuellement par l'intermédiaire de tringles souples formant des équerres de renvoi d'angle aux coins des ouvrants.Traditionally, these operating devices of the sash are also actuated by the rods mounted on the opening hardware, possibly by through flexible rods forming squares angle return to the corners of the opening.

Cependant, lors des manoeuvres de l'ouvrant, commandées par un organe de manoeuvre de la ferrure, le poids de l'ouvrant se répercute directement sur le dispositif de manoeuvre et tend à déplacer les tringles de manoeuvre plus rapidement que l'organe de manoeuvre manipulé par l'utilisateur. However, during the opening maneuvers, controlled by an operating member of the fitting, the the weight of the opening directly affects the operating device and tends to move the rods maneuver faster than the operating member handled by the user.

Il n'est pas rare alors que l'organe de manoeuvre échappe aux mains de l'utilisateur et que l'ouvrant termine brutalement son déplacement jusqu'à sa position de fermeture ou d'ouverture.It is not uncommon for the organ of maneuver escapes the user's hands and that the opening abruptly ends its movement until it closed or open position.

Cet effet est notamment observé pour les ouvrants coulissants par levage dans lesquels l'ouvrant est abaissé lors de sa fermeture. L'utilisateur doit alors contrer le poids de l'ouvrant en retenant l'organe de manoeuvre lors du mouvement de fermeture.This effect is particularly observed for sliding doors by lifting in which the door is lowered when it is closed. User must then counter the weight of the opening by retaining the organ maneuver during the closing movement.

La présente invention a pour but de résoudre les inconvénients précités et de proposer un dispositif de freinage du mouvement de la tringle de manoeuvre qui permette de conserver des dispositifs traditionnels (ferrure, dispositif de verrouillage, de manoeuvre, équerre de renvoi d'angle...) standardisés.The object of the present invention is to resolve the disadvantages mentioned above and to propose a device for braking of the movement of the operating rod which allows to keep traditional devices (fitting, locking, operating device, standardized angle return square ...).

Le dispositif de freinage de tringle pour ouvrant visé par l'invention comporte une ferrure, telle que crémone, crémone-serrure comprenant un organe de manoeuvre commandant le déplacement en translation d'une tringle, ladite tringle actionnant au moins un dispositif de manoeuvre de l'ouvrant.The rod braking device for opening covered by the invention comprises a fitting, such that cremone bolt, locking bolt comprising a maneuver controlling the translational movement of a rod, said rod actuating at least one opening device.

Conformément à l'invention, ce dispositif de freinage est caractérisé en ce qu'il comprend une tringle de liaison solidaire en translation de la tringle de manoeuvre et du dispositif de manoeuvre de l'ouvrant et un manchon en matériau élastique entourant la tringle de liaison et logé dans un boítier de frein, ce boítier de frein comportant des parois internes adaptées à comprimer le manchon autour de la tringle de liaison lorsque cette tringle est déplacée en translation.According to the invention, this device for braking is characterized in that it comprises a connecting rod secured in translation of the operating rod and operating device the opening and a sleeve of elastic material surrounding the connecting rod and housed in a brake housing, this brake housing having internal walls adapted to compress the sleeve around the rod link when this rod is moved in translation.

Le dispositif de freinage conforme à l'invention permet donc de freiner le mouvement de la tringle de liaison, et par là-même, celui de la tringle de manoeuvre lorsque l'ouvrant est déplacé par l'intermédiaire de l'organe de manoeuvre de la ferrure. The braking device according to the invention thus makes it possible to slow down the movement of the rod of link, and by that, that of the rod maneuver when the leaf is moved by through the fitting operating member.

Ce dispositif de freinage permet ainsi de s'opposer au poids de l'ouvrant et d'éviter le déplacement brutal de ce dernier.This braking device thus makes it possible to oppose the weight of the sash and avoid brutal displacement of the latter.

De préférence, le manchon comprend un tronçon cylindrique et un tronçon tronconique, centrés sur l'axe de la tringle de liaison, le boítier de frein comprenant un évidement ayant une portion de section cylindrique et une portion de section tronconique adaptées à loger le manchon.Preferably, the sleeve comprises a section cylindrical and a frustoconical section, centered on the axis of the connecting rod, the brake housing comprising a recess having a cylindrical section portion and a portion of frustoconical section adapted to accommodate the muff.

Cette forme particulière du manchon et du boítier de frein permet de freiner la translation de la tringle de liaison uniquement dans un sens de déplacement et de laisser libre le déplacement de la tringle dans son sens inverse de translation.This particular shape of the sleeve and brake housing slows the translation of the connecting rod only in one direction displacement and leave free the displacement of the rod in its opposite direction of translation.

Le déplacement de la tringle de liaison est ainsi freiné lorsque celle-ci se déplace dans un sens défini de la base du tronçon tronconique du manchon vers le sommet de ce dernier.The displacement of the connecting rod is thus braked when it moves in one direction defined from the base of the frustoconical section of the sleeve towards the top of the latter.

Selon un autre aspect de l'invention, un ouvrant coulissant par levage, comprenant une ferrure, telle que crémone, crémone-serrure, comprenant un organe de manoeuvre commandant le déplacement en translation d'une tringle actionnant au moins un dispositif de verrouillage de l'ouvrant et un dispositif de levage de l'ouvrant dans un plan du dormant, une tringle souple formant équerre de renvoi d'angle, reliant ladite tringle et des supports de roulement dudit dispositif de levage, est caractérisé en ce qu'un dispositif de freinage conforme à l'invention est fixé entre ladite tringle souple et un support de roulement du dispositif de levage de l'ouvrant.According to another aspect of the invention, an opening sliding by lifting, comprising a fitting, such as cremone bolt, bolt lock, comprising a maneuver controlling the translational movement of a rod actuating at least one device for locking of the sash and a lifting device opening it in a frame plane, a flexible rod forming angle return bracket, connecting said rod and bearing supports of said device lifting, is characterized in that a device for braking according to the invention is fixed between said flexible rod and a bearing support of the device of lifting the sash.

Ainsi, pour un ouvrant coulissant par levage, qui est soulevé lors de son ouverture, le dispositif de freinage permet de retenir le mouvement de la tringle lors de la fermeture de l'ouvrant. Thus, for a sliding leaf by lifting, which is lifted when opened, the braking helps to retain the movement of the rod when the opening is closed.

En référence tout d'abord à la figure 1, le dispositif de freinage conforme à l'invention est destiné à équiper un ouvrant 1 comportant de manière connue une ferrure de verrouillage ayant un boítier logeant un mécanisme (non représenté) commandé par un organe de manoeuvre (poignée, béquille) et adapté à déplacer une ou plusieurs tringles de manoeuvre 2, masquées traditionnellement par une têtière 3.Referring first to Figure 1, the braking device according to the invention is intended to equip an opening 1 comprising so known a locking fitting having a housing housing a mechanism (not shown) controlled by a operating device (handle, stand) and suitable for move one or more operating rods 2, traditionally masked by a headrest 3.

Les tringles de manoeuvre 2 peuvent supporter des organes de verrouillage, tels que pêne demi-tour, galet,... coopérant avec des gâches réalisées sur le dormant 4.The operating rods 2 can support locking members, such as a latch bolt, roller, ... cooperating with strikes made on the sleeping 4.

Le dispositif de freinage conforme à l'invention est destiné plus particulièrement aux ouvrants 1 dans lesquels la tringle de manoeuvre 2 actionne au moins un dispositif de manoeuvre 5 de l'ouvrant 1, tel qu'un dispositif de levage de l'ouvrant 1 dans un plan vertical, parallèle au plan du dormant 4.The braking device according to the invention is intended more particularly for opening 1 in which the operating rod 2 actuates at least one operating device 5 of the opening 1, such as a opening device 1 in one plane vertical, parallel to the frame plane 4.

En effet, lors de l'ouverture et/ou de la fermeture de ces ouvrants 1, le mouvement de la tringle de manoeuvre 2 est naturellement accéléré par l'effet du poids de l'ouvrant 1.Indeed, during the opening and / or the closing of these openings 1, the movement of the rod maneuver 2 is naturally accelerated by the effect of sash weight 1.

Un tel ouvrant comprend également une tringle souple formant équerre de renvoi d'angle 6 à un angle de l'ouvrant (l'angle inférieur sur la figure 1) solidaire de la tringle de manoeuvre 2. Such an opening also includes a rod flexible forming angle return angle 6 at an angle of the opening (the lower corner in Figure 1) integral of the operating rod 2.

Cette équerre de renvoi d'angle 6 est, dans les réalisations connues, directement ou par l'intermédiaire d'une deuxième tringle de manoeuvre, fixée au dispositif de manoeuvre 5 de l'ouvrant 1 afin de transmettre le mouvement de la tringle 2 à partir de la poignée ou béquille de l'ouvrant 1.This angle return square 6 is, in the known achievements, directly or through a second operating rod, fixed to the device operating 5 of the opening 1 in order to transmit the rod 2 movement from the handle or sash stand 1.

Conformément à l'invention, un dispositif de freinage 7 est fixé entre l'équerre de renvoi d'angle 6 et le dispositif de manoeuvre 5 de l'ouvrant 1.According to the invention, a device for braking 7 is fixed between the angle gear 6 and the operating device 5 of the opening 1.

Ce dispositif de freinage proprement dit va maintenant être décrit plus en détail en référence tout d'abord à la figure 7 et aux figures 2A à 2D, 3A et 3B.This actual braking device will now be described in more detail with reference all first in Figure 7 and Figures 2A to 2D, 3A and 3B.

Ce dispositif de freinage 7 comprend une tringle de liaison 8, telle qu'une tige cylindrique, et un manchon 9 en matériau élastique entourant la tringle de liaison 8 et logé dans un boítier de frein 10, ce boítier comportant des parois internes 10c adaptées à comprimer le manchon 9 autour de la tringle de liaison 8 lorsque la tringle de liaison 8 est déplacée en translation.This braking device 7 comprises a rod link 8, such as a cylindrical rod, and a sleeve 9 of elastic material surrounding the rod connection 8 and housed in a brake housing 10, this housing comprising internal walls 10c adapted to compress the sleeve 9 around the connecting rod 8 when the connecting rod 8 is moved in translation.

Le manchon 9 peut être en caoutchouc par exemple, de manière à pouvoir supporter la compression.The sleeve 9 can be made of rubber by example, so that it can withstand compression.

Il comporte en son centre un évidement cylindrique de section sensiblement supérieure à celle de la tringle de liaison 8 qui le traverse.It has in its center a recess cylindrical section significantly larger than that of the connecting rod 8 which passes through it.

Le manchon 9 comprend un tronçon cylindrique 9a et un tronçon tronconique 9b centrés sur un même axe x-x, confondu avec l'axe formé par la tringle de liaison 8.The sleeve 9 comprises a cylindrical section 9a and a frustoconical section 9b centered on the same axis x-x, coincides with the axis formed by the connecting rod 8.

De préférence, le manchon 9 comprend des entailles 9c, au nombre de quatre et réparties symétriquement par rapport à son axe central x-x sur la figure 3B.Preferably, the sleeve 9 comprises notches 9c, four in number and distributed symmetrically with respect to its central axis x-x on the Figure 3B.

Ces entailles 9c s'étendent parallèlement à cet axe central x-x, sur toute la hauteur du tronçon tronconique 9b et une partie du tronçon cylindrique 9a. These notches 9c extend parallel to this central axis x-x, over the entire height of the section frustoconical 9b and part of the cylindrical section 9a.

Ces entailles 9c facilitent la compression du manchon 9 sur la tringle de liaison 8 par les parois internes 10c du boítier de freinage 10.These notches 9c facilitate the compression of the sleeve 9 on the connecting rod 8 through the walls internal 10c of the brake box 10.

Ce dernier comprend également, comme illustré sur la figure 2A, un évidement central, s'étendant suivant l'axe x-x, ayant une portion de section transversale cylindrique 10a et une portion de section transversale tronconique 10b adaptées à loger le manchon 9, c'est-à-dire respectivement le tronçon cylindrique 9a et le tronçon tronconique 9b du manchon 9.The latter also includes, as illustrated in FIG. 2A, a central recess, extending along the x-x axis, having a section portion transverse cylindrical 10a and a section portion frustoconical transverse 10b adapted to accommodate the sleeve 9, that is to say respectively the cylindrical section 9a and the frustoconical section 9b of the sleeve 9.

La portion de section tronconique 10b est de dimension identique ou sensiblement plus réduite que celle du tronçon tronconique 9b du manchon 9.The portion of frustoconical section 10b is identical or significantly smaller in size than that of the frustoconical section 9b of the sleeve 9.

Afin de faciliter le montage du manchon 9, le boítier de frein 10 est en deux parties: un coffre 10' logeant l'évidement central précité et illustré aux figures 2A et 2B et une couvercle 10'' illustré aux figures 2C et 2D.In order to facilitate the mounting of the sleeve 9, the brake housing 10 is in two parts: a trunk 10 ' housing the aforementioned central recess and illustrated in Figures 2A and 2B and a 10 '' cover illustrated in Figures 2C and 2D.

Le couvercle 10'' comporte également un évidement cylindrique 10d adapté à venir en regard de la portion de section cylindrique 10a et à être traversé par la tringle de liaison 8.The 10 '' cover also has a cylindrical recess 10d adapted to come opposite the portion of cylindrical section 10a and to be crossed by the connecting rod 8.

De manière classique, le couvercle 10'' est fixé par rivetage au coffre 10' du boítier par des tétons 11 coopérant avec des orifices 12, au nombre de quatre dans cette réalisation.Conventionally, the 10 '' cover is fixed by riveting to the trunk 10 'of the case by nipples 11 cooperating with orifices 12, four in number in this achievement.

La portion tronconique 10b du coffre 10' se prolonge également par une ouverture cylindrique 10e débouchant sur la face du coffre 10' opposée à celle recevant le couvercle 10". La tringle de liaison 8 traverse ainsi cette ouverture cylindrique 10e, de sorte que l'ensemble du boítier de frein 10 et du manchon 9 est monté en coulissement sur la tringle de liaison 8.The frustoconical portion 10b of the trunk 10 'is also extends through a 10th cylindrical opening opening onto the face of the trunk 10 'opposite that receiving the 10 "cover. The connecting rod 8 thus passes through this cylindrical opening 10e, so that all of the brake housing 10 and the sleeve 9 is slidably mounted on the connecting rod 8.

Ce boítier de frein peut être moulé en alliage à base de zinc additionné d'aluminium et de magnésium, du type Zamak™. This brake housing can be molded from alloy zinc base added with aluminum and magnesium, Zamak ™ type.

Le dispositif de freinage comprend en outre un ressort 13 logé dans l'évidement 10a du boítier de frein 10. Ce ressort 13 est de préférence hélicoïdal et précontraint entre le tronçon cylindrique 9a du manchon 9 et la face d'extrémité du boítier de frein 10 constituée par le couvercle 10'' et par le coffre 10'.The braking device further comprises a spring 13 housed in the recess 10a of the brake housing 10. This spring 13 is preferably helical and prestressed between the cylindrical section 9a of the sleeve 9 and the end face of the brake housing 10 constituted by the cover 10 '' and by the trunk 10 '.

La section interne du ressort est supérieure à la section de la tringle de liaison 8 qui le traverse.The internal section of the spring is greater than the section of the connecting rod 8 which passes through it.

Le boítier de frein 10 comporte également des moyens de fixation 14 adaptés à fixer le boítier 10 à une têtière 3 s'étendant sensiblement parallèlement à la tringle 2 de la ferrure éventuellement prolongée par une tringle souple de renvoi d'angle 6.The brake housing 10 also includes fixing means 14 adapted to fix the housing 10 to a headrest 3 extending substantially parallel to the rod 2 of the fitting possibly extended by a flexible corner deflection rod 6.

Dans cet exemple, les moyens de fixation 14 sont constitués de deux ailes 14 de la largeur du coffre 10'. Ces ailes 14 sont adaptées à traverser une lumière 3a prévue à cet effet dans la têtière 3 et servent de guidage du boítier de frein 10 dans la lumière 3a de la têtière 3.In this example, the fixing means 14 are consisting of two wings 14 of the width of the trunk 10 '. These wings 14 are adapted to pass through a light 3a provided for this purpose in the headrest 3 and serve as guide the brake housing 10 in the lumen 3a of the headrest 3.

Cette lumière 3a est de longueur, dans la direction de l'axe x-x de la tringle de liaison 8, sensiblement supérieure à la longueur du boítier de frein 10 dans cette même direction, afin de permettre un mouvement transversal du boítier de frein dans cette lumière 3a lors du déplacement angulaire de la tringle de liaison 8, comme cela sera expliqué ci-dessous avec le fonctionnement du dispositif.This light 3a is of length, in the direction of the x-x axis of the connecting rod 8, significantly greater than the length of the housing brake 10 in this same direction, to allow a transverse movement of the brake housing in this light 3a during the angular displacement of the rod link 8, as will be explained below with the operation of the device.

Grâce à la forme tronconique du manchon 9 et du boítier 10, le dispositif de freinage est comprimé sur la tringle de liaison 8 seulement lorsque celle-ci se déplace de la base vers le sommet du tronçon tronconique 9b du manchon 9. En outre, la forme tronconique permet d'obtenir une compression progressive autour de la tringle de liaison 8. Thanks to the frustoconical shape of the sleeve 9 and the case 10, the braking device is compressed on the connecting rod 8 only when the latter moves from the base to the top of the frusto-conical section 9b of the sleeve 9. In addition, the frustoconical shape allows obtain progressive compression around the connecting rod 8.

Le tronçon cylindrique 9a du manchon permet un bon guidage du manchon 9 dans le boítier 10 et évite toute mise en travers.The cylindrical section 9a of the sleeve allows a good guidance of the sleeve 9 in the housing 10 and avoids any crossing.

Comme illustré à la figure 7 et aux figures 5A à 5C et 6A à 6C, une douille 15 est montée en rotation autour d'une extrémité 8a de la tringle de liaison 8.As illustrated in Figure 7 and Figures 5A to 5C and 6A to 6C, a bush 15 is mounted for rotation around one end 8a of the connecting rod 8.

Cette douille 15 est de forme sensiblement cylindrique, traversée sur sa longueur d'un évidement également cylindrique.This socket 15 is substantially shaped cylindrical, crossed over its length by a recess also cylindrical.

Pour la montage de la douille 15, l'extrémité 8a de la tringle 8 est prolongée par un téton 8d de section réduite qui est adapté à traverser l'évidement de la douille 15.For mounting the socket 15, the end 8a of the rod 8 is extended by a nipple 8d of section reduced which is suitable for crossing the recess of the socket 15.

Cette dernière vient ainsi en butée contre l'extrémité 8a de la tringle de liaison 8, au niveau de l'épaulement formé par le raccordement du téton 8d à cette extrémité 8a.The latter thus comes into abutment against the end 8a of the connecting rod 8, at the shoulder formed by the connection of the stud 8d to this end 8a.

L'extrémité libre du téton 8d est rivetée sur la douille 15 par l'intermédiaire d'une rondelle de sertissage de sorte que la douille 15 est immobilisée en translation sur la tringle de liaison 8 mais libre en rotation autour de l'axe x-x.The free end of the nipple 8d is riveted on the socket 15 by means of a washer crimping so that the sleeve 15 is immobilized in translation on the connecting rod 8 but free in rotation around the x-x axis.

Un support de douille 16 comporte un téton 17b ayant une extrémité 17a fixée à la tringle de la ferrure, c'est-à-dire à la tringle de manoeuvre 2 ou à la tringle de renvoi d'angle 6.A socket support 16 includes a stud 17b having one end 17a fixed to the rod of the fitting, i.e. to operating rod 2 or to the angle return rod 6.

Dans l'exemple illustré à la figure 1, le support de douille 16 est fixé à la tringle souple de renvoi d'angle 6, par sertissage de l'extrémité 17a du téton 17b sur une ouverture cylindrique prévue à cet effet dans la tringle souple 6.In the example illustrated in Figure 1, the socket holder 16 is fixed to the flexible rod of bevel gear 6, by crimping the end 17a of the stud 17b on a cylindrical opening provided for this effect in the flexible rod 6.

Le têtière 3, s'étendant parallèlement à la tringle souple 6, comporte une lumière oblongue 3b traversée par le téton 17b qui peut ainsi se déplacer librement en translation avec les tringles 2, 6 et 8, indépendamment de la têtière 3 fixe par rapport à l'ouvrant 1.The headrest 3, extending parallel to the flexible rod 6, has an oblong light 3b crossed by the stud 17b which can thus move freely in translation with the rods 2, 6 and 8, independently of the headrest 3 fixed with respect to opening it 1.

Cette lumière longitudinale 3b adaptée au passage du téton 17b est illustrée à la figure 4. Elle a une longueur suivant l'axe x-x adaptée au déplacement du téton 17b lors de la course de la tringle 2.This longitudinal light 3b adapted to passage of the stud 17b is illustrated in FIG. 4. It has a length along the x-x axis adapted to the displacement of the pin 17b during the stroke of the rod 2.

Le support de douille 16 est également constitué de deux parties 16', 16'', moulées en Zamak™, qui sont solidarisées autour de la douille 15 lors du montage.The socket support 16 also consists two 16 ', 16' 'parts, molded in Zamak ™, which are secured around the sleeve 15 during assembly.

Chaque partie 16' et 16'' comporte, sur leur face destinée à venir en regard, respectivement des tétons cylindriques 18 et des orifices cylindriques 19. Les tétons 18 sont introduits par force ou rivetés dans les orifices 19 lors de la fermeture du support de douille 16.Each 16 'and 16' 'section has, on their face intended to come opposite, respectively cylindrical nipples 18 and cylindrical orifices 19. The nipples 18 are introduced by force or riveted in the orifices 19 when the support for socket 16.

De même, chaque partie 16' et 16'' comporte en regard un évidement central 16a dont la section transversale correspond sensiblement à la moitié de la section de la douille 15 et deux évidements semi-circulaires 16b prolongeant l'évidement central 16a à chacune de ses extrémités.Similarly, each part 16 'and 16' 'has in look at a central recess 16a whose section transverse corresponds substantially to half the sleeve section 15 and two semi-circular recesses 16b extending the central recess 16a to each of its ends.

La dimension de ces évidements semi-circulaires correspond sensiblement à la moitié de la section de la tringle de liaison 8a et est également adaptée à loger la rondelle de sertissage de la douille 15 sur l'extrémité 8d de la tringle de liaison 8.The size of these semicircular recesses roughly corresponds to half the cross section of the connecting rod 8a and is also suitable for housing the crimp washer of the sleeve 15 on the end 8d of the connecting rod 8.

La douille 15 est ainsi montée immobile dans le support de douille 16, la tringle de liaison 8 pouvant pivoter librement dans la douille 15.The sleeve 15 is thus mounted stationary in the socket support 16, the connecting rod 8 being able pivot freely in the socket 15.

L'autre extrémité 8b de la tringle de liaison 8 est fixée à un dispositif de manoeuvre 5 de l'ouvrant 1, qui est dans cet exemple un dispositif de levage de l'ouvrant 1.The other end 8b of the connecting rod 8 is fixed to an operating device 5 of the opening 1, which in this example is a lifting device for opening it 1.

Ce dispositif de levage est connu en lui-même et ne sera pas décrit en détail ci-dessous. This lifting device is known in itself and will not be described in detail below.

Il comprend des chariots 5a à roulements doubles et des lumières faisant office de rampe 5b situées dans les parois latérales du chariot 5a.It includes 5a trolleys with double bearings and lights serving as a ramp 5b located in the side walls of the carriage 5a.

Des tétons 5c solidaires de supports de roulement 5d circulent dans les lumières 5b.5c nipples secured to support bearing 5d circulate in the lights 5b.

L'extrémité 8b de la tringle de liaison 8 est fixée aux supports de roulement 5d du chariot.The end 8b of the connecting rod 8 is attached to the carriage 5d bearing supports.

Pour cela, cette extrémité 8b est solidaire d'un boítier 20 comprenant deux tétons 21 alignés suivant un axe Y-Y, adaptés à être montés en rotation sur le dispositif de levage 5 de l'ouvrant 1, et plus précisément dans des orifices circulaires prévus à cet effet dans les parois latérales des supports de roulement 5d du dispositif de levage 5.For this, this end 8b is integral with a housing 20 comprising two pins 21 aligned along a Y-Y axis, adapted to be mounted in rotation on the lifting device 5 of the sash 1, and more precisely in circular holes provided for this effect in the side walls of the supports bearing 5d of the lifting device 5.

Ce boítier 20, moulé en Zamak™, comprend un évidement cylindrique 20a, débouchant à l'une de ses extrémités 20b, de section transversale légèrement supérieure à celle de l'extrémité 8b de la tringle de liaison 8 qui vient se loger dans cet évidement 20a.This case 20, molded in Zamak ™, includes a cylindrical recess 20a, opening at one of its ends 20b, slightly cross section greater than that of the end 8b of the rod link 8 which is housed in this recess 20a.

L'extrémité 8b de tringle 8 comporte en outre deux orifices 8c destinés à loger deux vis pointeaux (non représentées) traversant deux alésages 20c ménagés dans une face latérale du boítier 20.The rod end 8b 8 further comprises two holes 8c intended to accommodate two needle screws (not shown) passing through two bore 20c provided in a side face of the housing 20.

Ces fixations par vis permettent de solidariser la tringle de liaison 8 au boítier 20.These screw fasteners make it possible to secure the link rod 8 to the housing 20.

Le montage du dispositif de freinage 7 est ainsi relativement simple.The mounting of the braking device 7 is thus relatively simple.

On monte tout d'abord le manchon 9 dans le coffre 10' du boítier de frein 10 jusqu'à ce que son tronçon tronconique 9b vienne en butée sur la portion de section tronconique 10b du boítier 10.We first mount the sleeve 9 in the trunk 10 'of the brake box 10 until its frustoconical section 9b comes into abutment on the portion of frustoconical section 10b of the housing 10.

Le ressort 13 est ensuite introduit dans la portion de section cylindrique 10a du coffre 10', puis le couvercle 10'' riveté sur le coffre 10'.The spring 13 is then introduced into the portion of cylindrical section 10a of the trunk 10 ', then the cover 10 '' riveted to the trunk 10 '.

L'ensemble ainsi constitué est engagé sur la tringle de liaison 8 sur laquelle il coulisse avec un léger frottement du manchon 9 sur la tringle de liaison 8 du fait de la précontrainte réalisée par le ressort 13 sur le manchon 9.The assembly thus constituted is engaged on the connecting rod 8 on which it slides with a slight friction of the sleeve 9 on the connecting rod 8 due to the prestress produced by the spring 13 on the sleeve 9.

L'extrémité 8a de la tringle est ensuite sertie dans la douille 15 puis le support de douille 16 est monté autour de la douille 15.The end 8a of the rod is then crimped in socket 15 then socket holder 16 is mounted around the socket 15.

L'autre extrémité 8b de la tringle de liaison 8 est fixée dans le boítier 20 grâce à des vis pointeaux introduites dans les alésages 20c et les orifices 8c de la tringle 8.The other end 8b of the connecting rod 8 is fixed in the housing 20 by means of needle screws introduced into the bores 20c and the orifices 8c of the rod 8.

Le support de douille 16 est ensuite fixé à l'extrémité de la tringle souple 6 de l'équerre de renvoi d'angle, le téton 17b traversant la lumière 3b de la têtière 3 et l'extrémité 17a du téton 17b étant rivetée sur la tringle souple 6.The socket support 16 is then fixed to the end of the flexible rod 6 of the bracket angle gear, the pin 17b passing through the light 3b of the headrest 3 and the end 17a of the stud 17b being riveted on the flexible rod 6.

La position définitive du boítier de frein 10 peut alors être réalisée, par introduction des ailes 14 dans la lumière 3a réalisée à l'extrémité de la têtière 3.The final position of the brake housing 10 can then be carried out, by introduction of the wings 14 in the light 3a made at the end of the headrest 3.

Le boítier 20 peut ensuite être monté en rotation sur le support de roulement 5d du dispositif de levage 5.The housing 20 can then be mounted in rotation on the bearing support 5d of the lifting 5.

Lors du fonctionnement, l'organe de manoeuvre est actionné par un utilisateur, de manière à déplacer les tringles 2 et 6 en translation, de haut en bas et de la gauche sur la droite lors de la fermeture de l'ouvrant tel que représenté à la figure 1, et de bas en haut et de la droite vers la gauche de la figure 1 lors de l'ouverture de l'ouvrant.During operation, the operating member is operated by a user, so as to move the rods 2 and 6 in translation, from top to bottom and from the left on the right when closing the opening as shown in Figure 1, and from bottom to top and from right to left in Figure 1 when opening of the opening.

Ce mouvement est indiqué par les flèches F (Fermeture) et O (Ouverture).This movement is indicated by the arrows F (Closing) and O (Opening).

Lors de l'ouverture, la tringle de liaison 8 se déplace ainsi dans un sens contraire au sens d'action du manchon 9 du dispositif de freinage, c'est-à-dire du sommet vers la base du tronçon tronconique. When opening, the connecting rod 8 thus moves in a direction opposite to the direction of action of the sleeve 9 of the braking device, i.e. vertex towards the base of the frustoconical section.

Ceci a pour effet de supprimer la précontrainte du manchon 9 sur la tringle de liaison 8 et de laisser libre le mouvement d'ouverture de l'ouvrant au cours duquel celui-ci est soulevé par le déplacement du support de roulement 5d grâce à la rampe 5d dans laquelle se déplace le téton 5c du dispositif de levage 5.This has the effect of removing the prestress of the sleeve 9 on the connecting rod 8 and leave free opening movement of the sash during from which it is raised by the displacement of the 5d bearing support thanks to the 5d ramp in which moves the pin 5c of the lifting device 5.

Le ressort 13 empêche le manchon 9 d'être entraíné dans la portion de section cylindrique 10a du boítier de frein 10.The spring 13 prevents the sleeve 9 from being driven in the cylindrical section portion 10a of the brake housing 10.

Le mouvement d'ouverture n'est donc pas freiné et un palier 5'b est généralement prévu à l'extrémité de la rampe 5b pour supporter le poids de l'ouvrant 1 lorsqu'il est relevé.The opening movement is therefore not slowed down and a 5'b bearing is generally provided at the end of the ramp 5b to support the weight of the sash 1 when raised.

Lors de l'ouverture, l'extrémité 8b de la tringle de liaison 8 suit le mouvement du support de roulement 5d alors que l'extrémité 8a de la tringle de liaison 8 reste solidaire de la tringle souple 6 de renvoi d'angle.When opening, the end 8b of the connecting rod 8 follows the movement of the support bearing 5d while the end 8a of the rod connection 8 remains integral with the flexible rod 6 of angle reference.

Or, le support de roulement 5d est éloigné de la traverse de l'ouvrant 1 alors que la tringle souple 6 de renvoi souple reste immobile par rapport à l'ouvrant 1.However, the bearing support 5d is distant from the cross member of the opening 1 while the flexible rod 6 of flexible return remains stationary relative to the opening 1.

Ce mouvement est rendu possible grâce au montage en rotation du boítier 20 autour des tétons 21 sur le support de roulement 5d.This movement is made possible thanks to the mounting in rotation of the housing 20 around the nipples 21 on the bearing support 5d.

Une inclinaison de la tringle de liaison 8 est ainsi obtenue sans déformation de cette tringle 8.An inclination of the connecting rod 8 is thus obtained without deformation of this rod 8.

En outre, la lumière 3a de la têtière autorise un mouvement transversal du boítier de frein 10 qui accompagne l'inclinaison de la tringle de liaison 8.In addition, the light 3a of the headrest authorizes a transverse movement of the brake housing 10 which accompanies the inclination of the connecting rod 8.

Au moment de la fermeture en revanche, le poids de l'ouvrant 1 s'exerce sur la rampe 5b du dispositif de levage et tend à rappeler brutalement la tringle de liaison dans le sens de la flèche F.At the time of closing, however, the weight of the opening 1 is exerted on the ramp 5b of the device lifting and tends to abruptly recall the rod link in the direction of arrow F.

Or, à la position finale d'ouverture, le ressort 13 a exercé une action de rappel sur le manchon 9 qui est logé dans la portion de section tronconique 10b du boítier de frein 10a et légèrement comprimé sur la tringle de liaison 8.However, in the final opening position, the spring 13 exerted a return action on the sleeve 9 which is housed in the tapered section portion 10b of the brake housing 10a and slightly compressed on the connecting rod 8.

A la fermeture, ce frottement du manchon 9 et la poussée du ressort 13 ont tendance à déplacer le manchon 9 dans le sens de la flèche F, à l'intérieur de la portion de section tronconique 10b du boítier de frein 10.On closing, this friction of the sleeve 9 and the spring thrust 13 tend to move the sleeve 9 in the direction of arrow F, inside the portion of frustoconical section 10b of the brake housing 10.

Ce déplacement génère progressivement un frottement de plus en plus important du manchon 9 sur la tringle de liaison 8, jusqu'à pouvoir bloquer cette tringle en translation si l'utilisateur lâche l'organe de manoeuvre.This displacement gradually generates a more and more friction of the sleeve 9 on the connecting rod 8, until it can block this rod in translation if the user releases the organ maneuver.

Lorsque l'utilisateur maintient l'organe de manoeuvre, il contrebalance, avec l'aide du dispositif de freinage 7, l'effet du poids accélérant le déplacement des tringles 2, 6 et 8.When the user maintains the maneuver, it counterbalances, with the help of the device braking 7, the effect of the weight accelerating the displacement of the rods 2, 6 and 8.

Le dispositif de freinage conforme à l'invention permet ainsi de conserver une standardisation des organes classiques d'un ouvrant coulissant par levage (équerre de renvoi d'angle 6, dispositif de levage 5,...).The braking device according to the invention thus allows standardization of conventional elements of a sliding leaf by lifting (angle return square 6, lifting device 5, ...).

Bien entendu, de nombreuses modifications peuvent être apportées à l'exemple décrit ci-dessus sans sortir du cadre de l'invention comme définie dans la revendication 1.Of course, many modifications can be made to the example described above without depart from the scope of the invention as defined in claim 1.

Ainsi, le dispositif de freinage peut être utilisé pour d'autres types d'ouvrants coulissants.So the braking device can be used for other types of sliding doors.

Il peut également être utilisé sur des ouvrants coulissants ayant des fonctions annexes de décalage ou de soufflet au lieu de celles de levage.It can also be used on sashes sliding with additional offset functions or bellows instead of lifting ones.

La tringle de liaison 8 pourrait également être réalisée dans un matériau souple afin d'autoriser sa déformation élastique à partir de son point fixe, au niveau de sa liaison avec la tringle souple 6 de renvoi d'angle. The connecting rod 8 could also be made of a flexible material to allow its elastic deformation from its fixed point, at level of its connection with the flexible return rod 6 angle.

Le boítier de liaison 20, fixant l'autre extrémité 8b de la tringle de liaison 8 au support de roulement 5d, pourrait alors être monté fixe sur le support de roulement 5d, la tringle de liaison 8 se déformant lors du levage du support de roulement 5d.The connection box 20, fixing the other end 8b of the connecting rod 8 to the support 5d bearing, could then be fixedly mounted on the bearing support 5d, the link rod 8 is deforming when lifting the bearing support 5d.
