Abstract

The mechanism comprises a calliper (4) made from elastic wire in the shape of a U, having turned-over ends (43) engaging with holes (200,31) in both the sliding components and the bars. The two sides of the calliper pass through angled slots (50) in lugs (5) on the sides of the sliding components, positioned so that the movement of the calliper side in the slots in one direction causes them to disengage from the holes and allow the sliding components to be adjusted relative to the bars. The base of the U-shaped calliper is in the form of a handle, and the slots in the lugs (5) are angled at 45 degrees to the vertical. <IMAGE>

Description

La présente invention concerne un dispositif de verrouillage / déverrouillage en translation d'une rallonge par rapport à un élément de mobilier tel qu'un lit ou un fauteuil.The present invention relates to a locking / unlocking device in translation of an extension relative to a piece of furniture such as a bed or an armchair.

Elle concerne également l'élément de mobilier ainsi équipé.It also relates to the element of furniture thus equipped.

Des lits disponibles sur le marché, en particulier ceux qui équipent les hôpitaux, sont équipés d'un cadre supportant le sommier qui est pourvu d'une rallonge coulissante. Ceci permet de donner au lit une longueur adaptable à la taille de la personne occupant ce lit.Beds available on the market, in particular those fitted to hospitals, are equipped with a frame supporting the bed base which is provided with a sliding extension. This makes it possible to give the bed a length adaptable to the size of the person occupying this bed.

De manière générale, la rallonge comporte deux profilés longitudinaux et parallèles qui peuvent coulisser sur des tiges solidaires du lit. Les profilés présentent chacun un trou transversal tandis que les tiges présentent chacune une série de trous similaires de sorte que les profilés peuvent être disposés par rapport aux tiges de manière à faire correspondre les trous entre eux et permettre l'introduction de moyens de verrouillage, c'est-à-dire de blocage en translation de la rallonge.Generally, the extension comprises two longitudinal and parallel profiles which can slide on rods integral with the bed. The profiles each have a transverse hole while the rods each have a series of similar holes so that the profiles can be arranged relative to the rods so as to match the holes together and allow the introduction of locking means, c 'that is to say in translation lock of the extension.

Ce type d'équipement se trouve également sur certains fauteuils, pour le positionnement et le réglage d'un coussin faisant office d'appui-jambes.This type of equipment is also found on certain armchairs, for positioning and adjusting a cushion acting as a leg support.

Les moyens de verrouillage comprennent le plus souvent des ressorts, des cliquets ou autres pièces mécaniques à enfoncer ou à déplacer.The locking means most often comprise springs, pawls or other mechanical parts to be pushed in or moved.

Ces mécanismes de verrouillage / déverrouillage mettent en oeuvre plusieurs pièces mécaniques susceptibles de se bloquer ou de se casser et dont l'actionnement peut provoquer certains incidents, notamment des coincements de doigts. De plus, la manoeuvre de verrouillage / déverrouillage requiert une certaine dextérité et, pour l'opérateur, la compréhension du geste à faire n'est pas toujours facile.These locking / unlocking mechanisms use several mechanical parts capable of blocking or breaking and the actuation of which can cause certain incidents, notably pinching of fingers. In addition, the locking / unlocking maneuver requires a certain dexterity and, for the operator, understanding the gesture to be made is not always easy.

La présente invention a pour but de fournir un dispositif de verrouillage / déverrouillage efficace qui présente un nombre de pièces mécaniques réduit au minimum, dont l'actionnement est facile, rapide et sans risque d'incidents, notamment des coincements de doigts.The object of the present invention is to provide an effective locking / unlocking device which has a number of mechanical parts reduced to a minimum, the actuation of which is easy, rapid and without risk of incidents, in particular trapped fingers.

Ce dispositif de verrouillage / déverrouillage en translation d'une rallonge par rapport à un élément de mobilier, tel que mentionné ci-dessus, est caractérisé en ce que les moyens de verrouillage consistent en un étrier en fil élastiquement déformable, en forme générale de "U", dont les extrémités libres sont rabattues pour pouvoir pénétrer dans les trous et en ce qu'il est prévu sur chacun des profilés des moyens formant rampe qui coopèrent avec une branche latérale de l'étrier en "U", et qui sont conformés de telle manière qu'un effort sur l'étrier tendant à le faire pivoter autour de l'axe matérialisé par les extrémités rabattues provoque une déformation de l'étrier qui fait ressortir les extrémités rabattues de l'un des trous et, par conséquent, le déverrouillage de la rallonge, tandis qu'un relâchement de cet effort provoque le mouvement inverse, c'est-à-dire l'introduction des extrémités rabattues dans ledit trou et le verrouillage de la rallonge.This locking / unlocking device in translation of an extension relative to a piece of furniture, as mentioned above, is characterized in that the locking means consist of an elastically deformable wire stirrup, in the general form of " U ", the free ends of which are folded down so as to be able to penetrate the holes and in that there is provided on each of the profiles of the means forming a ramp which cooperate with a lateral branch of the stirrup in" U ", and which are shaped of such so that a force on the stirrup tending to rotate it around the axis materialized by the folded ends causes a deformation of the stirrup which brings out the folded ends of one of the holes and, consequently, the unlocking of the extension, while a relaxation of this force causes the reverse movement, that is to say the introduction of the folded ends into said hole and the locking of the extension.

Ainsi, à l'aide d'une seule et même pièce en forme générale de "U", on va pouvoir réaliser le verrouillage ou le déverrouillage de la rallonge sans avoir aucunement recours des pièces munies de cliquets ou de ressorts. De plus le verrouillage / déverrouillage des deux côtés longitudinaux de la rallonge va pouvoir être réalisé en manoeuvrant ce seul et unique élément.Thus, using a single piece in the general shape of "U", we will be able to achieve the locking or unlocking of the extension without having any recourse to parts with pawls or springs. In addition, the locking / unlocking of the two longitudinal sides of the extension can be carried out by operating this one and only element.

Le cadre de lit 1, représenté partiellement à la figure 1, comporte deux profilés longitudinaux 10 formés de tubes creux métalliques de section carrée. Entre ces profilés sont prévues deux plaques transversales 11 et 12.The bed frame 1, partially shown in Figure 1, has two longitudinal sections 10 formed of hollow metal tubes of square section. Between these profiles are provided two transverse plates 11 and 12.

Parallèlement et à distance des profilés 10 sont montées deux tiges plates, parallèles et longitudinales 3 en métal. Chaque tige, disposée dans un plan vertical, est montée du côté interne des profilés 10, ce qui signifie que les deux tiges 3 se font face. Elles sont rendues solidaires des profilés au moyen de pièces de fixation 30.In parallel and at a distance from the profiles 10 are mounted two flat, parallel and longitudinal metal rods 3. Each rod, arranged in a vertical plane, is mounted on the internal side of the sections 10, which means that the two rods 3 face each other. They are made integral with the profiles by means of fastening parts 30.

Elles s'étendent depuis la plaque 11 jusqu'à sensiblement l'extrémité libre des profilés 10. Bien entendu, leur longueur est définie en fonction de la distance sur laquelle on souhaite procéder à l'extension de la rallonge.They extend from the plate 11 to substantially the free end of the profiles 10. Of course, their length is defined as a function of the distance over which it is desired to extend the extension.

Chaque tige est percée d'une série de trous 31 d'axe horizontal répartis régulièrement sur toute la longueur. Dans une variante de réalisation, ces trous peuvent être répartis de manière non régulière, de manière à pouvoir mettre en place la rallonge dans des positions prédéterminées.Each rod is pierced with a series of holes 31 with a horizontal axis distributed regularly over the entire length. In an alternative embodiment, these holes can be distributed in an irregular manner, so that the extension can be put in place in predetermined positions.

La rallonge 2 comporte deux profilés longitudinaux et parallèles 20, réunis à l'une de leurs extrémités, par une plaque transversale 21.The extension 2 comprises two longitudinal and parallel sections 20, joined at one of their ends, by a transverse plate 21.

Les profilés 20 ont une section en forme de "U" dont la base 202 est disposée verticalement, c'est-à-dire parallèlement aux tiges 3. Ils sont disposés de telle manière que leurs ailes 201 soient à l'opposé les unes des autres. Les profilés 20 peuvent coulisser le long des tiges 3, les ailes 201 étant disposées de part et d'autre des chants inférieur et supérieur des tiges 3.The sections 20 have a "U" shaped section, the base 202 of which is arranged vertically, that is to say parallel to the rods 3. They are arranged in such a way that their wings 201 are opposite each other. other. The profiles 20 can slide along the rods 3, the wings 201 being arranged on either side of the lower and upper edges of the rods 3.

Non loin de son extrémité opposée à la plaque 21, chaque profilé 20 comporte au niveau de la base 202, un trou transversal 200 d'axe horizontal. On comprend que selon la position de la rallonge par rapport au cadre de lit, on peut faire coïncider le trou 200 avec l'un ou l'autre des trous 31 des tiges 3, en vue d'y introduire des moyens de verrouillage.Not far from its opposite end to the plate 21, each section 20 has at the base 202, a transverse hole 200 of horizontal axis. It is understood that depending on the position of the extension relative to the bed frame, the hole 200 can be made to coincide with one or the other of the holes 31 of the rods 3, in order to introduce locking means.

Par ailleurs, les deux profilés 20 sont pourvus, sur la face externe de leur base 202, c'est-à-dire sur leurs côtés qui se font face, d'une pièce 5, par exemple en matière plastique.Furthermore, the two sections 20 are provided, on the external face of their base 202, that is to say on their opposite sides, with a part 5, for example made of plastic.

Sa hauteur correspond à celle de la base 202 et elle en est rendue solidaire, par exemple par collage, par une face plane latérale 51. Vue de face (figure 3), cette pièce comporte deux parois inférieure 53 et supérieure 52 horizontales qui se raccordent d'une part par un élément de paroi curviligne 54 et d'autre part par la face latérale 51.Its height corresponds to that of the base 202 and it is made integral with it, for example by gluing, by a lateral flat face 51. Viewed from the front (FIG. 3), this part has two horizontal lower 53 and upper 52 walls which are connected on the one hand by a curvilinear wall element 54 and on the other hand by the lateral face 51.

Dans cette pièce, qui présente une certaine épaisseur, est percé longitudinalement un alésage oblong 50, disposé de manière oblique. La partie inférieure de ce trou est disposée du côté du profilé 20 et, de manière avantageuse, les bords longitudinaux et parallèles de l'alésage forment avec la verticale un angle a d'environ 45°.In this part, which has a certain thickness, an oblong bore 50 is pierced longitudinally, arranged obliquely. The lower part of this hole is disposed on the side of the section 20 and, advantageously, the longitudinal and parallel edges of the bore form an angle α of approximately 45 ° with the vertical.

Les moyens de verrouillage consistent en un étrier en fil métallique 4, en forme générale de "U". Cet étrier comporte une base 40 qui s'étend parallèlement et à proximité de la traverse 21 de la rallonge.The locking means consist of a metal wire stirrup 4, in the general shape of "U". This stirrup has a base 40 which extends parallel and close to the cross member 21 of the extension.

Les extrémités de la base 40 se poursuivent par deux parties obliques 41 formant un angle obtus avec celle-ci. Ces deux parties se raccordent chacune à une branche latérale 42 qui s'étend parallèlement aux profilés 20 et aux tiges 3. Les extrémités libres 43 de ces branches sont rabattues à angle droit pour pouvoir pénétrer dans les trous 31 et 200 précédemment cités, réalisant ainsi le verrouillage de la rallonge par rapport au cadre de lit (voir figure 2). Ces extrémités 43, alignées l'une par rapport à l'autre, matérialisent un axe de pivotement XX'.The ends of the base 40 are continued by two oblique parts 41 forming an obtuse angle with the latter. These two parts are each connected to a lateral branch 42 which extends parallel to the profiles 20 and to the rods 3. The free ends 43 of these branches are folded down at right angles so as to be able to penetrate the holes 31 and 200 previously cited, thus achieving locking the extension in relation to the bed frame (see figure 2). These ends 43, aligned with respect to each other, materialize a pivot axis XX '.

On notera que l'ensemble de l'étrier est disposé dans un même plan et que les branches latérales 42 traversent l'alésage 50 prévu dans chaque pièce 5. Dans une autre forme de réalisation, les parties 41 peuvent former avec les branches 42 un certain angle dans un plan vertical, de sorte que la base 40 se situe dans un plan différent de celui des extrémités 43.It will be noted that the whole of the stirrup is arranged in the same plane and that the lateral branches 42 pass through the bore 50 provided in each part 5. In another embodiment, the parts 41 can form with the branches 42 a certain angle in a vertical plane, so that the base 40 is located in a plane different from that of the ends 43.

Dans la position de verrouillage montrée à la figure 1, les branches s'appuient sur le rebord inférieur des alésages 50. C'est également la position illustrée aux figures 5A et 5B.In the locking position shown in Figure 1, the legs are supported on the lower edge of the bores 50. This is also the position illustrated in Figures 5A and 5B.

Nous allons maintenant expliquer la manière dont on procède pour réaliser le déverrouillage de la rallonge.We will now explain how to proceed to unlock the extension.

D'une main, on saisit la base 40 de l'étrier qui fait office de poignée.With one hand, grab the base 40 of the stirrup which acts as a handle.

On actionne la base 40 dans le sens de la flèche f (figures 4 et 7A) de manière à provoquer un mouvement de pivotement de l'étrier vers le haut, autour de l'axe XX' cité plus haut.The base 40 is actuated in the direction of the arrow f (FIGS. 4 and 7A) so as to cause the pivoting movement of the stirrup upwards, around the axis XX 'mentioned above.

Pendant cette opération, chaque branche latérale 42 est contrainte de se déplacer vers le haut le long des alésages 50 qui font offices de rampe. Les branches 41 et 42 se rapprochent sous l'effet de coincement provoqué par l'angle a de chaque alésage (figure 7B).During this operation, each lateral branch 42 is forced to move upwards along the bores 50 which act as ramps. Branches 41 and 42 are approaching under the jamming effect caused by the angle a of each bore (FIG. 7B).

Il s'opère donc une flexion de chacune des branches de sorte que les extrémités rabattues 43 se dégagent partiellement des trous 31 et 200 le débattement est suffisant pour qu'il y ait un retrait des extrémités 43 des trous 31 (flèche g, figure 4). De cette façon, les extrémités 43 ne bloquent plus la rallonge en translation.There is therefore a bending of each of the branches so that the folded ends 43 partially emerge from the holes 31 and 200 the clearance is sufficient for there to be a withdrawal of the ends 43 of the holes 31 (arrow g , Figure 4 ). In this way, the ends 43 no longer block the extension in translation.

En maintenant l'étrier, il suffit simplement de faire coulisser la rallonge le long du cadre de lit pour lui faire occuper la position désirée.Holding the bracket, simply slide the extension along the bed frame to make it occupy the desired position.

En relâchant l'étrier, sous l'action de son propre poids et de l'élasticité du fil de métal, les branches 42 retombent au fond des alésages 50, en étant guidés par les bords et les extrémités rabattues 43 de l'étrier rentrent dans les trous 31, en réalisant ainsi le verrouillage.By releasing the stirrup, under the action of its own weight and the elasticity of the metal wire, the branches 42 fall back to the bottom of the bores 50, being guided by the edges and the folded ends 43 of the stirrup return in holes 31, thereby achieving locking.

Les pièces 5 sont disposées sensiblement à un tiers de la distance entre l'axe XX' et la partie 40 de l'étrier, du côté des trous 200. Cette position peut varier en fonction du débattement de l'étrier souhaité, de la souplesse du fil de l'étrier et de la course nécessaire au blocage de la rallonge par les extrémités 43.The parts 5 are arranged substantially at a third of the distance between the axis XX 'and the part 40 of the stirrup, on the side of the holes 200. This position can vary according to the travel of the desired stirrup, the flexibility of the stirrup wire and the stroke necessary to block the extension by the ends 43.
