Abstract

The hospital bed comprises a frame with a sleeping plane on which a mattress (3) is placed. It is fitted along one of its longitudinal sides with a barrier (5) able to occupy two end positions. In the first position the barrier is erected vertically with its top located at a higher level than the mattress upper surface. In the second retracted position the barrier top is located at a level lower than that of the mattress upper surface. There are lateral position adjusters (200,200',8) for the barrier in its erected position.

Description

La présente invention se rapporte à un lit, notamment hospitalier, qui comporte un cadre de lit avec un plan de couchage sur lequel est disposé un matelas et qui est équipé, au moins le long d'un de ses côtés longitudinaux, d'au moins un élément de barrière.The present invention relates to a bed, particularly hospital bed, which comprises a bed frame with a sleeping surface on which is arranged a mattress and which is equipped, at least along one of its longitudinal sides, at least a barrier element.

Par l'expression "lit hospitalier", on entend tout lit équipé de moyens, mécanisés ou non, qui permettent de porter assistance à l'individu qui y repose. De tels lits sont notamment susceptibles d'être utilisés dans les hôpitaux proprement dits, mais également dans des maisons de repos, de retraite, ou même chez des particuliers, pour autant que ceux-ci ne disposent pas d'une autonomie complète.The term "hospital bed" means any bed equipped with means, mechanized or not, which can assist the individual who rests there. Such beds are particularly likely to be used in hospitals themselves, but also in nursing homes, retirement homes, or even in private homes, as long as they do not have complete autonomy.

Le ou les éléments de barrière qui équipent ces lits sont susceptibles d'occuper deux positions extrêmes, à savoir :

  • une première position érigée verticale dans laquelle ils s'étendent au voisinage dudit matelas, leur sommet se situant à un niveau supérieur à celui de la surface supérieure du matelas, de manière à constituer un moyen de retenue de l'occupant du lit, prévenant la chute accidentelle de ce dernier ;
  • une seconde position escamotée, généralement à l'aplomb de la précédente, dans laquelle leur sommet se situe à un niveau au moins inférieur à celui de la surface supérieure du matelas, de manière à permettre notamment à l'occupant de quitter le lit.
The barrier element or elements that equip these beds are likely to occupy two extreme positions, namely:
  • a first vertical erect position in which they extend in the vicinity of said mattress, their top being at a level higher than that of the upper surface of the mattress, so as to constitute a means of restraining the occupant of the bed, preventing the accidental fall of the latter;
  • a second retracted position, generally in line with the previous one, in which their summit is at a level at least less than that of the upper surface of the mattress, so as to allow the occupant to leave the bed.

Cette structure est notamment décrite dans le document FR-A-2 815 518 au nom du présent demandeur. La barrière peut, en plus des deux positions précitées, occuper une position verrouillée intermédiaire dans laquelle elle est écartée du lit et s'étend partiellement au-dessus du plan de couchage.This structure is particularly described in the document FR-A-2,815,518 on behalf of the present applicant. The barrier may, in addition to the two aforementioned positions, occupy an intermediate locked position in which it is spaced from the bed and extends partially above the coating plane.

Les constructeurs de ces lits sont tenus de respecter de nombreuses normes, et notamment des normes particulièrement drastiques en matière de sécurité, plus particulièrement des caractéristiques dimensionnelles des barrières, compte tenu du matelas et des accessoires qui équipent le lit.The manufacturers of these beds are required to comply with many standards, including particularly stringent standards in terms of safety, especially the dimensional characteristics of the barriers, given the mattress and accessories that equip the bed.

Malgré toutes les précautions prises, il arrive que l'on rencontre des situations d'accident dues au fait que certains patients agités ou désorientés se trouvent coincés entre le matelas et l'élément de barrière en position érigée.Despite all the precautions taken, accident situations may occur due to the fact that some agitated or disoriented patients are trapped between the mattress and the barrier element in erected position.

Bien entendu, les personnes les plus alertes arrivent à se dégager de cette situation, mais d'autres restent coincés entre le matelas et la barrière. Dans certains cas extrêmes, de tels accidents ont entraîné la mort du patient.Of course, the most alert people manage to get out of this situation, but others are stuck between the mattress and the barrier. In some extreme cases, such accidents resulted in the death of the patient.

Pour éviter de telles situations, chaque constructeur recommande aux établissements qui achètent leurs lits d'utiliser un matelas dont la largeur est adaptée pour réduire au minimum l'écartement entre chacune des faces verticales et longitudinales du matelas, et l'élément de barrière attenant.To avoid such situations, each builder recommends that establishments purchasing their beds use a mattress whose width is adapted to minimize the spacing between each of the vertical and longitudinal faces of the mattress, and the adjoining barrier element.

Dans la pratique, et du fait qu'il existe sur le marché de nombreux matelas de largeurs différentes, il est prévisible que malgré les recommandations du fabricant du lit, les soignants optent pour des combinaisons matelas/lit présentant des risques de piégeage, par exemple en créant un espace important entre l'élément de barrière et le matelas.In practice, and because there are many mattresses of different widths on the market, it is foreseeable that, despite the recommendations of the bed manufacturer, caregivers will opt for mattress / bed combinations with trapping risks, for example creating an important gap between the barrier element and the mattress.

A l'inverse, d'autres utilisateurs souhaitent employer des matelas relativement larges, de sorte qu'il n'est alors plus possible d'amener les éléments de barrière en position érigée et de les verrouiller correctement.Conversely, other users wish to use relatively large mattresses, so that it is no longer possible to bring the barrier elements into the erected position and lock them correctly.

Le document EP-A-0 315 438 décrit un lit thérapeutique dont le plan de couchage est prévu basculant autour d'un axe médian longitudinal. Au dessus du plan de couchage sont montés des éléments latéraux de contention destinés à être plaqués contre le corps du patient. Ces éléments sont formés de deux panneaux rembourrés et reliés par une base qui peut également être rembourrée afin que le patient puisse y faire reposer ses bras.The document EP-A-0 315 438 discloses a therapeutic bed whose sleeping surface is provided tilting about a longitudinal median axis. Above the lying plane are mounted lateral compression elements intended to be pressed against the body of the patient. These elements are formed of two padded panels and connected by a base which can also be padded so that the patient can rest his arms.

Ces éléments ne s'étendent pas le long des côtés longitudinaux du lit et ne peuvent être assimilés à des barrières.These elements do not extend along the longitudinal sides of the bed and can not be assimilated to barriers.

La présente invention a pour but de pallier les inconvénients mentionnés plus haut en proposant un lit qui puisse s'adapter au mieux aux différentes largeurs de matelas du commerce, en particulier de manière à limiter au maximum le risque d'accident du type de celui décrit plus haut.The present invention aims to overcome the drawbacks mentioned above by providing a bed that can best adapt to different widths of commercial mattresses, in particular so as to minimize the risk of accidents of the type described above. upper.

Ainsi, la présente invention propose un lit, notamment hospitalier, selon la revendication 1.Thus, the present invention provides a bed, particularly hospital, according to claim 1.

Ainsi, grâce à ces moyens de réglage qui peuvent être automatiques, on va adapter au mieux la position relative de l'élément de barrière érigé par rapport au matelas en place sur le lit, de manière à réduire au minimum l'intervalle qui les sépare, ce qui permet d'éviter la situation d'accident telle que décrite plus haut.Thus, thanks to these adjustment means which can be automatic, it will best adapt the relative position of the barrier element erected relative to the mattress in place on the bed, so as to minimize the gap between them , which avoids the accident situation as described above.

Par ailleurs, selon d'autres caractéristiques avantageuses mais non limitatives :

  • ledit élément de barrière est agencé à la manière d'un parallélogramme déformable, le passage de ladite première à ladite seconde position, et inversement, se faisant exclusivement dans le sens longitudinal ;
  • l'appui de la face interne de l'élément de barrière en position érigée contre la face longitudinale correspondante du matelas conditionne l'engagement dans l'une des au moins deux ouvertures.
  • lesdites ouvertures sont disposées selon une ligne droite à l'aplomb de la trajectoire courbe de la seconde extrémité dudit bras, et lesdits moyens de réglage comprennent également un volet apte à obturer par recouvrement au moins une des ouvertures de verrouillage non sélectionnées, afin que le doigt puisse s'engager dans l'ouverture adéquate ;
  • ledit volet est pivotant et comporte une face supérieure formant rampe apte à permettre son franchissement par le doigt en vue de son engagement dans ladite ouverture adéquate, un déplacement du doigt dans le sens inverse provoquant le pivotement du volet et le découvrement de l'ouverture correspondante ;

Moreover, according to other advantageous but non-limiting characteristics:
  • said barrier element is arranged in the manner of a deformable parallelogram, the passage from said first to said second position, and vice versa, being exclusively in the longitudinal direction;
  • the support of the inner face of the barrier element in the erected position against the corresponding longitudinal face of the mattress conditions the engagement in one of the at least two openings.
  • said openings are arranged in a straight line in line with the curved path of the second end of said arm, and said adjusting means also comprise a cover capable of covering by overlapping at least one of the lock openings not selected, so that the finger can engage in the proper opening;

Le lit représenté très schématiquement est un lit connu en soi auquel l'invention est susceptible de s'appliquer. Il est constitué d'un châssis 1 formé d'un cadre métallique 10 plein, auquel sont rattachées des roulettes 11 délimitant entre elles une forme rectangulaire allongée.The bed shown very schematically is a bed known per se to which the invention is applicable. It consists of a frame 1 formed of a solid metal frame 10, to which are attached wheels 11 delimiting between them an elongated rectangular shape.

Le cadre supporte des équipements 12 de relevage et d'abaissement de la partie couchage du lit, destinés notamment à faciliter l'intervention du personnel hospitalier. De tels équipements sont également prévus pour positionner le patient dans des positions dites de sécurité, notamment de proclive et de déclive.The frame supports equipment 12 for raising and lowering the sleeping part of the bed, intended in particular to facilitate the intervention of hospital staff. Such equipment is also provided to position the patient in so-called safety positions, including proclive and declivity.

Bien entendu, le châssis est susceptible de recevoir d'autres équipements mécaniques et/ou électroniques, aptes à coopérer avec la partie couchage du lit.Of course, the chassis is likely to receive other mechanical equipment and / or electronic, able to cooperate with the sleeping part of the bed.

A ce châssis et/ou au plan de couchage sont également fixés des panneaux verticaux de tête et de pied de lit, non représentés ici. Ils délimitent transversalement les extrémités longitudinales du lit.To this frame and / or to the sleeping plane are also fixed vertical panels of head and footboard, not shown here. They delimit transversely the longitudinal ends of the bed.

De façon connue en soi, la partie couchage du lit est essentiellement formée de ce que l'on désignera, dans l'ensemble de la présente demande, sous le vocable "plan de couchage", référencé 2, c'est-à-dire une surface confondue ou située juste au-dessous de la face inférieure du matelas et qui est le plus souvent constituée d'un plan dur en plusieurs parties, l'une au moins de ces parties étant mobile de manière à occuper des positions différentes de l'horizontale.In a manner known per se, the bedding portion of the bed is essentially formed of what will be referred to throughout the present application, under the term "sleeping plan", referenced 2, that is to say a surface which is merged or located just below the underside of the mattress and which is most often constituted of a hard plane in several parts, at least one of these parts being movable so as to occupy different positions of the horizontal.

Ceci permet notamment, par inclinaison de l'une et/ou l'autre de ces parties, de mettre le patient dans une position similaire à celle qu'il occuperait dans un fauteuil.This allows, in particular, by inclination of one and / or the other of these parts, to put the patient in a position similar to that he would occupy in a chair.

Ce lit est équipé, le long de chacun de ses côtés longitudinaux, d'éléments de barrière référencés 5. Conformément à l'invention, c'est la valeur de "l'écartement" j entre le matelas et les éléments 5 que l'on souhaite adapter à la largeur du matelas, afin de réduire au maximum le risque de coincement dans cette zone.This bed is equipped, along each of its longitudinal sides, barrier elements referenced 5. According to the invention, it is the value of "spacing" j between the mattress and the elements 5 that the it is desired to adapt to the width of the mattress, in order to minimize the risk of jamming in this area.

Sur cette figure sont également représentés en traits interrompus, des aménagements conformes à l'invention, qui seront décrits ultérieurement.In this figure are also shown in dashed lines, arrangements according to the invention, which will be described later.

Le lit représenté plus en détail aux figures 2 et 3 est typiquement un lit susceptible d'intégrer les moyens conformes à l'invention.The bed shown in more detail in Figures 2 and 3 is typically a bed capable of integrating the means according to the invention.

Il est décrit en détail dans le document WO-A-02/32271 au nom du présent demandeur. On pourra s'y reporter en cas de besoin.It is described in detail in the document WO-A-02/32271 on behalf of the present applicant. We can refer to it when needed.

Toutefois, pour faciliter la lecture de la suite dans la description, nous en ferons ci-après une description succincte.However, to facilitate the reading of the continuation in the description, we will make a short description below.

Ce lit a une structure généralement analogue à celle qui a été donnée plus haut. Les références identiques à celles utilisées à la figure 1 désignent les mêmes équipements.This bed has a structure generally similar to that which has been given above. References identical to those used in figure 1 designate the same equipment.

Le lit est équipé d'un élément de barrière 5 à deux panneaux 5' et 5" articulés l'un par rapport à l'autre. Ils s'étendent parallèlement à l'un de ses côtés longitudinaux. Pour des raisons de clarté des dessins, un élément similaire, susceptible d'équiper le second côté, n'a pas été représenté.The bed is equipped with a barrier element 5 with two panels 5 'and 5 "articulated with respect to one another and extend parallel to one of its longitudinal sides. drawings, a similar element, likely to equip the second side, was not shown.

Il s'agit de panneaux en forme de plaques généralement rectangulaires. Leurs dimensions sont sensiblement similaires, de telle manière que lorsqu'ils sont superposés l'un par rapport à l'autre (figure 2) dans une position dite "rabattue", ils occupent l'encombrement d'un seul élément.These are panels in the form of generally rectangular plates. Their dimensions are substantially similar, so that when they are superimposed with respect to each other ( figure 2 ) in a so-called "folded" position, they occupy the bulk of a single element.

En direction longitudinale, ils présentent une dimension au plus égale à la moitié de la longueur du matelas. De cette façon, lorsqu'ils sont déployés, ils occupent pratiquement l'intégralité de la longueur du matelas.In the longitudinal direction, they have a dimension at most equal to half the length of the mattress. In this way, when they are deployed, they occupy practically the entire length of the mattress.

Dans une variante de réalisation, le premier élément pourrait occuper sensiblement les trois quarts de la longueur du lit et le second, le dernier quart.In an alternative embodiment, the first element could occupy substantially three quarters of the length of the bed and the second, the last quarter.

Dans encore une autre forme de réalisation, les éléments pourraient être au nombre de trois et occuper chacun, au plus le tiers de la longueur du lit.In yet another embodiment, the elements could be three in number and occupy each, at most one third of the length of the bed.

A la figure 2, on a symbolisé par la flèche h le mouvement de relevage des éléments de barrières. La position escamotée de cette figure est particulièrement utile lorsque le personnel hospitalier souhaite accéder au lit sans être gêné dans ses mouvements. En effet, dans cette position, le sommet des panneaux 5 et 5' est situé à un niveau inférieur à celui de la surface supérieure du matelas 3. Cette position permet également à l'occupant du lit de le quitter, sans difficultés.To the figure 2 , arrow symbol h indicates the lifting movement of the barrier elements. The retracted position of this figure is particularly useful when the hospital staff wishes to access the bed without being disturbed in its movements. Indeed, in this position, the top of the panels 5 and 5 'is located at a lower level than the upper surface of the mattress 3. This position also allows the occupant of the bed to leave without difficulty.

Les panneaux 5' et 5" sont articulés l'un par rapport à l'autre autour d'un axe XX' qui est généralement perpendiculaire à l'axe longitudinal du lit. Ainsi, après relevage dans le sens de la flèche h, on peut les déployer l'un par rapport à l'autre, comme le montrent les flèches f et g.The panels 5 'and 5 "are articulated with respect to one another about an axis XX' which is generally perpendicular to the longitudinal axis of the bed, thus, after lifting in the direction of the arrow h, one can unfold them in relation to each other, as shown by the arrows f and g.

Aux figures 4 et 7 est représenté partiellement un système 50 qui permet de positionner et de verrouiller les éléments de barrières 5' et 5" en position rabattue au-dessus ou au-dessous du plan de couchage.To the Figures 4 and 7 is partially shown a system 50 which allows to position and lock the barrier elements 5 'and 5 "in the folded position above or below the coating plane.

On y a référencé par 500 un bras central et principal qui fait partie intégrante du système 50 cité plus haut, à parallélogramme déformable.There is referenced by 500 a central and main arm which is an integral part of the system 50 mentioned above, deformable parallelogram.

Le panneau 5' est articulé en haut de ce bras autour d'un axe 501 parallèle à l'axe longitudinal du lit, tandis que le bras lui-même est articulé par rapport au châssis du lit autour d'un axe parallèle 502.The panel 5 'is articulated at the top of this arm about an axis 501 parallel to the longitudinal axis of the bed, while the arm itself is hinged relative to the frame of the bed about a parallel axis 502.

On a désigné par la référence 20 une pièce de verrouillage solidaire du châssis de lit. Cette pièce, ouverte vers l'extérieur, comporte une paroi de fond 206 généralement verticale, qui s'étend parallèlement à l'axe longitudinal du lit, encadré par deux ailes parallèles, verticales et transversales.20 has designated a locking piece integral with the bed frame. This piece, open towards the outside, has a bottom wall 206 generally vertical, which extends parallel to the longitudinal axis of the bed, flanked by two parallel wings, vertical and transverse.

Elle se poursuit vers le bas par une paroi inclinée 205, dite "de verrouillage", formant un angle obtus avec la paroi de fond. Enfin, elle est également délimitée par une paroi de couverture 208 généralement horizontale. Il comporte, sur chacune des parois 205 et 208, une ouverture 200, respectivement 201 associée à un arrêtoir 203, respectivement 204.It continues downwards by an inclined wall 205, called "locking", forming an obtuse angle with the bottom wall. Finally, it is also bounded by a generally horizontal cover wall 208. It comprises, on each of the walls 205 and 208, an opening 200, respectively 201 associated with a stop 203, respectively 204.

Le bras central 500 est creux et à son extrémité peut coulisser un doigt de verrouillage 503. Ce doigt est monté élastiquement dans le bras et mis sur contrainte par un ressort non visible, de façon à ce que son extrémité dépasse toujours du bras 500'. Il est relié à un câble d'actionnement 504.The central arm 500 is hollow and at its end can slide a locking pin 503. This finger is resiliently mounted in the arm and stressed by a non-visible spring, so that its end always exceeds the arm 500 '. It is connected to an actuating cable 504.

Un mécanisme de commande à distance, non représenté, et positionné par exemple sur le panneau 5', permet de tirer sur le câble et d'actionner le doigt.A remote control mechanism, not shown, and positioned for example on the panel 5 ', allows to pull on the cable and operate the finger.

Dans la position de la figure 4, les panneaux 5' et 5" s'étendent au-dessus du plan de couchage du lit et le doigt 503 est engagé dans l'ouverture 200 de la pièce 20. Pour déverrouiller les panneaux dans cette position, il faut alors agir sur le câble 504, afin que le doigt ressorte de son logement.In the position of the figure 4 , the panels 5 'and 5 "extend above the sleeping surface of the bed and the finger 503 is engaged in the opening 200 of the part 20. To unlock the panels in this position, it is then necessary to act on the cable 504, so that the finger comes out of its housing.

En position escamotée en dessous du plan de couchage (figure 6) le doigt est alors logé dans l'ouverture 201 et là encore, il est nécessaire d'actionner le câble 504 pour changer de position.In retracted position below the sleeping surface ( figure 6 ) the finger is then housed in the opening 201 and again, it is necessary to actuate the cable 504 to change position.

Tel est l'état de la technique connu du document WO-A-02/32271 précité, relatif aux moyens de verrouillage de l'élément de barrière.This is the state of the art known from the document WO-A-02/32271 above, relating to the locking means of the barrier element.

Dans le cadre de la présente invention, ces moyens de verrouillage sont globalement inchangés, mais ceux-ci sont combinés à des moyens de réglage de la position latérale de l'élément de barrière en position érigée, qui permettent de réduire, autant que faire se peut, l'intervalle entre l'élément de barrière et la face longitudinale correspondante du matelas que reçoit le lit.In the context of the present invention, these locking means are globally unchanged, but these are combined with means for adjusting the lateral position of the barrier element in the erected position, which make it possible to reduce, as far as possible, the gap between the barrier element and the corresponding longitudinal side of the mattress that the bed receives.

Ces moyens sont plus spécifiquement décrits en référence aux figures 8 à 14 annexées. Cependant, les références identiques à celles déjà utilisées plus avant désignent les mêmes objets et ne seront donc pas à nouveau décrits en détail.These means are more specifically described with reference to the Figures 8 to 14 attached. However, references identical to those already used earlier designate the same objects and will not be described again in detail.

Par rapport au mode de réalisation décrit plus haut et conforme à l'état de la technique, la pièce 20 conserve la paroi de fond 206 généralement verticale, parallèle à l'axe longitudinal du lit, encadrée par deux ailes parallèles, verticales et transversales 207.Compared to the embodiment described above and in accordance with the state of the art, the piece 20 retains the generally vertical bottom wall 206, parallel to the longitudinal axis of the bed, flanked by two parallel, vertical and transverse wings 207 .

La paroi de fond se poursuit, comme déjà décrit plus haut, vers le bas, entre les deux ailes 207, par une paroi inclinée 205 dite "de verrouillage", formant un angle obtus avec ladite paroi de fond.The bottom wall continues, as already described above, downwards, between the two wings 207, by an inclined wall 205 called "locking" forming an obtuse angle with said bottom wall.

Sur les figures 11 et 12, on a référencé C, la portion de courbe décrite par l'extrémité inférieure du bras 500 lors de son mouvement de rotation autour de l'axe 502. Comme on le voit nettement, la paroi 205 est parallèle à une tangente à cette courbe. Elle s'étend à proximité immédiate de cette courbe fictive, sans toutefois interférer avec elle.On the Figures 11 and 12 , reference C, the curve portion described by the lower end of the arm 500 during its rotational movement about the axis 502. As can be seen clearly, the wall 205 is parallel to a tangent to this curve. It extends in the immediate vicinity of this fictional curve, without interfering with it.

Ainsi que cela est particulièrement visible aux figures 8 et 9, sont formées dans la paroi 205 deux ouvertures de verrouillage 200 et 200'. Ces ouvertures sont alignées et disposées à l'aplomb de la courbe C, dans la partie médiane de la paroi. L'ouverture 200 est celle qui est la plus proche de l'extrémité libre de la paroi 205.As this is particularly visible in Figures 8 and 9 are formed in the wall 205 two locking openings 200 and 200 '. These openings are aligned and arranged at right angles to the curve C, in the median part of the wall. The opening 200 is the one that is closest to the free end of the wall 205.

A ces ouvertures est associé un volet plat pivotant 8, reposant par sa face inférieure sur la face supérieure de la paroi 205.To these openings is associated a pivoting flat flap 8, resting by its lower face on the upper face of the wall 205.

Il a, vu de dessus, une forme rectangulaire allongée et est articulé par rapport à la paroi 205, autour d'un axe 80 perpendiculaire à cette dernière.It has, seen from above, an elongated rectangular shape and is hinged relative to the wall 205, about an axis 80 perpendicular to the latter.

Deux butées 7 et 7' en forme de quarts de sphère font saillie de la paroi 205 et limite le débattement angulaire du volet 8. Ces butées sont disposées de telle manière que lorsque le volet est en appui contre la face plane de la butée 7, il recouvre totalement l'ouverture de verrouillage 200', sans interférer avec l'ouverture 200, tandis que lorsqu'il est en appui contre la face plane de la butée 7', il découvre totalement l'ouverture 200', tout en étant escamoté dans une direction opposée à l'ouverture 200.Two abutments 7 and 7 'in the form of quarter-sphere protrude from the wall 205 and limit the angular displacement of the flap 8. These stops are arranged in such a way that when the flap bears against the flat face of the abutment 7, it completely covers the locking opening 200 ', without interfering with the opening 200, whereas when it bears against the flat face of the abutment 7', it completely discovers the opening 200 ', while being retracted in a direction opposite to the opening 200.

Ainsi qu'on le comprend aisément à la comparaison des figures 8, 9 et 10, le volet présente une partie antérieure 81, située au voisinage de l'axe 80, qui présente une épaisseur constante. Elle se prolonge par une partie d'extrémité postérieure 82 dont la face supérieure inclinée 820 forme rampe. Cette pente s'étend transversalement par rapport aux grands côtés du rectangle dans lequel s'inscrit le volet. Elle est ascendante en direction de l'extrémité libre de la paroi 205.As can easily be understood from the comparison of Figures 8, 9 and 10 , the flap has an anterior portion 81, located in the vicinity of the axis 80, which has a constant thickness. It is extended by an end part posterior 82 whose inclined upper face 820 forms a ramp. This slope extends transversely with respect to the long sides of the rectangle in which the flap fits. It is ascending towards the free end of the wall 205.

La face 820 s'étend ici sensiblement sur la moitié de la surface du volet. Dans une autre forme de réalisation, cette proportion pourrait être moindre. Il est cependant nécessaire que la rampe se situe, quand le volet occupe la position en butée de la figure 8, à l'aplomb de la courbe C évoquée plus haut.The face 820 here extends substantially over half of the surface of the flap. In another embodiment, this proportion could be less. However, it is necessary that the ramp is located, when the shutter occupies the position in abutment of the figure 8 , in line with the curve C mentioned above.

Nous allons maintenant décrire, en référence aux figures 11 à 15, la manière dont on verrouille l'élément de barrière 5 en position érigée, selon que l'on a affaire à un matelas plus ou moins étroit.We will now describe, with reference to Figures 11 to 15 the manner in which the barrier element 5 is locked in the erected position, depending on whether one is dealing with a more or less narrow mattress.

Les figures 11 et 12 illustrent le cas d'un matelas 3 relativement étroit. Cela correspond à la situation de la figure 1 dans laquelle le matelas est représenté en traits continus et présente une largeur L.The Figures 11 and 12 illustrate the case of a relatively narrow mattress 3. This corresponds to the situation of the figure 1 wherein the mattress is shown in solid lines and has a width L.

Pour la clarté des figures 11 et 12, les moyens de support du matelas n'ont pas été représentés. De plus, l'élément de barrière y a été représenté par un seul trait mixte 5 censé correspondre à la paroi du panneau 5" faisant face au matelas 3.For the sake of clarity Figures 11 and 12 , the support means of the mattress have not been represented. In addition, the barrier element has been represented by a single dotted line intended to correspond to the wall of the panel 5 "facing the mattress 3.

Lors de l'érection de l'élément 5, le bras 500 décrit une portion de courbe centrée sur l'axe 502. Il s'agit de la courbe C précitée.During the erection of the element 5, the arm 500 describes a portion of the curve centered on the axis 502. This is the aforementioned curve C.

Du fait de la position inclinée de la paroi 205, le volet occupe la position de la figure 8 dans laquelle il s'appuie contre la butée 7 et obture l'ouverture 200.Due to the inclined position of the wall 205, the shutter occupies the position of the figure 8 in which it bears against the stop 7 and closes the opening 200.

Lors du mouvement précité, l'extrémité du doigt de verrouillage 503 engagé dans le bras 500 rencontre la face inclinée 820 formant pente du vole 8. Le doigt se rétracte progressivement dans le bras, jusqu'à franchir totalement le volet.During the aforementioned movement, the end of the locking pin 503 engaged in the arm 500 meets the inclined face 820 forming a slope of the fly 8. The finger retracts gradually in the arm, to fully cross the flap.

Dans la mesure où le matelas n'est pas assez large pour contrarier la fin du mouvement de la patte autour de l'axe 502, le doigt 503 vient à rencontrer l'ouverture 200 et à s'engager dans celle-ci. C'est la situation de la figure 12.Insofar as the mattress is not wide enough to thwart the end of the movement of the tab around the axis 502, the finger 503 comes to meet the opening 200 and engage therein. This is the situation of the figure 12 .

L'écartement j qui subsiste entre le matelas 3 et l'élément de barrière 5 est réduit au minimum, évitant ainsi tout risque d'accident.The gap j that remains between the mattress 3 and the barrier element 5 is minimized, thus avoiding any risk of accident.

A la figure 12, on a représenté en traits interrompus, dans le prolongement du matelas 3, l'encombrement que présenterait un matelas plus large.To the figure 12 there is shown in dashed lines, in the extension of the mattress 3, the size that would present a wider mattress.

Ce matelas, de largeur L', est représenté en traits interrompus à la figure 1. On y retrouve, symbolisés de la même façon, les éléments de barrière 5 dans une nouvelle position adaptée à ce matelas.This mattress, of width L ', is represented in dashed lines at the figure 1 . There is, symbolized in the same way, the barrier elements 5 in a new position adapted to this mattress.

Les moyens selon la présente invention permettent donc d'autoriser un verrouillage de l'élément de barrière, malgré la largeur plus importante du matelas.The means according to the present invention therefore allow to allow locking of the barrier element, despite the greater width of the mattress.

Le mode opératoire permettant d'arriver à la situation de la figure 13 est analogue à celui décrit en référence à la figure 11.The procedure for arriving at the situation of the figure 13 is similar to that described with reference to the figure 11 .

Cependant, le matelas présentant une largeur importante, l'appui de l'élément de barrière sur ce dernier s'oppose, sauf effort important, à ce que le doigt 503 s'enclenche dans l'ouverture 200, après qu'il ait franchi le volet 8.However, the mattress having a large width, the support of the barrier element on the latter is opposed, except significant effort, so that the finger 503 engages in the opening 200, after he has crossed part 8.

Dès lors que le doigt a franchi la rampe 820, l'appui de l'élément de barrière 5 contre le matelas tend à imprimer à la patte 500 un mouvement inverse du précédent. Ce faisant, le doigt 503 repousse le volet 8 contre la butée 7', tandis qu'il s'engage dans l'ouverture 200'. On atteint alors la position de verrouillage de la figure 15, dans laquelle il subsiste également, comme dans le cas précédent un jeu minimum j entre le matelas et l'élément de barrière.Once the finger has crossed the ramp 820, the support of the barrier element 5 against the mattress tends to print the leg 500 a reverse movement of the previous. In doing so, the finger 503 pushes the flap 8 against the stop 7 ', while it engages in the opening 200'. We then reach the lock position of the figure 15 , in which there is also, as in the previous case, a minimum clearance j between the mattress and the barrier element.

Compte tenu du fait que l'élément de barrière 5 est susceptible d'occuper deux positions différentes, la valeur de l'intervalle qui le sépare du chant correspondant des panneaux de tête 4 et de pied 4' de lit peut varier.In view of the fact that the barrier element 5 is capable of occupying two different positions, the value of the gap which separates it from the corresponding edge of the head panels 4 and the foot 4 'of the bed can vary.

Afin que cet intervalle ne puisse être suffisamment grand pour générer des risques de coincement d'un membre, on équipe ces panneaux de brides, comme cela est illustré à la figure 16.In order that this gap can not be large enough to generate a risk of jamming of a limb, these flange panels are equipped, as illustrated in FIG. figure 16 .

En effet, sur cette figure est représenté un panneau de tête de lit 4, dont les chants verticaux opposés sont pourvus de brides 14 en forme de U. Cette solution permet d'augmenter artificiellement la largeur du panneau, tandis que la forme ajourée, à claire voix des brides évite que l'on s'y coince les doigts. Lorsque l'élément de barrière est en position érigée, on réduit ainsi la distance entre cet élément et le panneau 4. De cette manière, on respecte les règles dimensionnelles normatives.Indeed, in this figure is shown a headboard 4, whose opposite vertical edges are provided with U-shaped flanges 14. This solution makes it possible to artificially increase the width of the panel, while the openwork shape, to Clear voice of the bridles prevents fingers from getting caught. When the barrier element is in the erected position, the distance between this element and the panel 4 is thus reduced. In this way, the normative dimensional rules are respected.

A la lecture qui vient d'être faite, on comprend que le verrouillage de l'élément de barrière 5, en fonction de la largeur du matelas est automatique et "intuitive". C'est en effet l'appui de la face interne de l'élément de barrière en position érigée contre la face correspondante du matelas qui conditionne l'engagement dans l'une ou l'autre des ouvertures.At the reading just made, it is understood that the locking of the barrier element 5, depending on the width of the mattress is automatic and "intuitive". It is in fact the support of the inner face of the barrier element in erected position against the corresponding face of the mattress which conditions the engagement in one or other of the openings.

Bien entendu, la disposition relative des deux ouvertures 200 et 200' devra être prévue en fonction des largeurs les plus courantes de matelas, ceci afin que l'élément de barrière puisse être verrouillé facilement, quel que soit le cas qui se présente.Of course, the relative arrangement of the two openings 200 and 200 'should be provided according to the most common widths of mattress, so that the barrier element can be locked easily, whatever the case that occurs.

Dans une forme de réalisation non représentée, le nombre d'ouvertures de verrouillage pourrait être plus important, de manière à pouvoir s'adapter à un nombre encore plus important de modèles de matelas.In an embodiment not shown, the number of locking openings could be larger, so as to adapt to an even larger number of mattress models.

Dans l'exemple de réalisation présenté ici, les moyens de réglage de la position latérale de l'élément de barrière en position érigée sont combinés aux moyens de verrouillage de cet élément de barrière. Ce n'est pas forcément le cas. Ainsi, les moyens de réglage peuvent être prévus indépendants des moyens de verrouillage.In the embodiment shown here, the means for adjusting the lateral position of the barrier element in the erected position are combined with the locking means of this barrier element. This is not necessarily the case. Thus, the adjustment means may be provided independently of the locking means.

Enfin, les moyens de l'invention peuvent s'appliquer à des éléments de barrière autres que ceux décrits ici. Il s'agit tout particulièrement de ceux qui sont agencés à la manière d'un parallélogramme déformable, le passage de la première position érigée à la seconde position escamotée, et inversement, se faisant exclusivement dans le sens longitudinal.Finally, the means of the invention can be applied to barrier elements other than those described here. It is particularly those which are arranged in the manner of a deformable parallelogram, the passage from the first erected position to the second retracted position, and vice versa, being exclusively in the longitudinal direction.
