Description

La présente invention concerne les meubles tels que lits ou fauteuils dont une partie est d'inclinaison réglable. The present invention relates to furniture such as beds or chairs of which is adjustable tilt. Elle vise plus particulièrement les lits dont la tête et/ou le pied sont relevables, ou inclinables. It is more particularly the beds which the head and / or foot can be lifted, or reclining.

De tels lits sont bien connus, notamment dans le domaine médical. Such beds are well known, particularly in the medical field. A l'origine, le relevage des têtes et pieds de lits se faisait manuellement. Originally, the raising of the heads and feet of beds was done manually. Actuellement, surtout dans le domaine de la literie domestique, la tendance est à la motorisation des commandes d'inclinaison de tête et/ou de pied de lit. Currently, especially in the field of household linen, the trend is motorization head tilt controls and / or footboard

C'est ainsi qu'ont été proposés des sommiers spéciaux, notamment à lattes, comprenant différentes parties articulées les unes sur les autres, et des vérins électriques adaptés à soulever chacune de ces parties. This led to proposed special mattresses, including laths, including different parts hinged to each other, and electric actuators adapted to raise each part.

Cependant, de tels sommiers pourvus de nombreuses articulations sont difficiles à réaliser, et, de ce fait, relativement onéreux. However, such mattresses filled many joints are difficult to perform, and, therefore, relatively expensive.

La présente invention a pour objectif premier la transformation de tous types de literies en literies à tête et/ou pied relevable ou inclinable. The present invention aims primarily the transformation of all types of bedding in bedding head and / or lift or tilt foot.

On a déjà proposé, par exemple dans le document WO-A-92 09520, un dispositif d'inclinaison de tête et/ou de pied de lit comprenant deux moyens d'appui ou châssis articulés l'un sur l'autre et un moyen de commande motorisé permettant de régler leur écartement relatif, ledit dispositif pouvant être installé de manière amovible sur un lit classique, entre le sommier et le matelas. It has already been proposed, for example in WO-A-92 09520, a head inclination and / or footboard comprising two support means or frames articulated to one another and means motorized control for adjusting their relative spacing, said device being detachably installed on a conventional bed, between the box spring and mattress. Malheureusement, le moyen de commande est placé à l'intérieur du périmètre défini par les châssis en sorte qu'il n'est pas possible d'obtenir la position horizontale et, dans cette position, de profiter de la coopération du matelas avec le sommier. Unfortunately, the control means is placed inside the perimeter defined by the frame so that it is not possible to get the horizontal position and in this position, to enjoy the cooperation of the mattress with box spring .

Pour pallier cet inconvénient, on a proposé également, selon US-A-4 853 990, un dispositif du genre ci-dessus dans lequel le moyen de commande n'est pas placé à l'intérieur du périmètre défini par les châssis : malheureusement, celui-ci est agencé de telle sorte que la position complètement horizontale ne peut, là non plus, être atteinte et l'angle de levage est limité. To overcome this drawback, it has also been proposed according to US-A-4,853,990, a device of the above kind wherein the control means is not positioned within the perimeter defined by the frame: unfortunately, it is arranged such that the completely horizontal position can not, either, be reached and the lifting angle is limited.

La présente invention a pour but de proposer un dispositif d'inclinaison de tête et/ou de pied de lit ne présentant pas les inconvénients ci-dessus. The present invention aims to propose a head tilt and / or footboard does not have the above drawbacks.

A cet effet, l'invention propose un dispositif d'inclinaison de tête et/ou de pied de lit, comprenant deux moyens d'appui ou châssis articulés l'un sur l'autre et un moyen de commande intervenant entre lesdits châssis pour régler leur écartement relatif, ledit dispositif pouvant être installé de manière amovible sur un lit comportant un sommier et un matelas, un châssis dit dormant étant destiné à reposer sur ledit sommier et un châssis dit mobile étant destiné à supporter une extrémité dudit matelas, lesdits châssis étant disposés en un V dont l'ouverture est réglable, le châssis dormant comportant deux tubes s'étendant parallèlement dans un même plan et le châssis mobile étant constitué d'un cadre en U monté pivotant sur et entre lesdits tubes, ledit moyen de commande étant attaché au châssis dormant et adapté à commander, par l'intermédiaire de vis sans fin, la translation longitudinale de sabots montés coulissant le long desdits tubes, et dont To this end, the invention proposes a head biasing means and / or footboard, comprising two support means or frames articulated to one another and a control means acting between said chassis to adjust their relative spacing, said device being installed in a removable manner on a bed comprising a base and a mattress, a frame said frame being intended to rest on said base and a frame movable said being for supporting one end of said mattress, said frames being arranged in a V whose opening is adjustable, the fixed frame comprising two tubes extending parallel in the same plane and the movable frame being constituted by a U-shaped frame mounted to pivot on and between said tubes, said control means being attached to the fixed frame and adapted to control, via the worm, the longitudinal translation of shoes mounted sliding along said tubes, and including le déplacement commande l'inclinaison du châssis mobile par rapport au châssis dormant, caractérisé en ce que les vis sans fin associées aux sabots sont logées dans lesdits deux tubes qui s'étendent longitudinalement et le moyen de commande est situé à l'extérieur de l'aire embrassée par le châssis dormant. the displacement control the inclination of the mobile frame relative to the fixed frame, characterized in that the endless screw associated with the shoes are accommodated in said two tubes which extend longitudinally and the control means is located outside of the 'area encompassed by the window frame.

La mise en oeuvre de ce dispositif permet donc de faire d'une literie de type fixe classique une literie à tête et/ou pied inclinables sous la commande d'un moteur. The implementation of this device makes it possible to make a conventional fixed bed type bedding to head and / or reclining foot under the control of a motor. La présente invention, ne nécessitant pas la mise en oeuvre de sommiers articulés, résout les problèmes, notamment de coût, des literies à tête et/ou pied inclinables connues à l'heure actuelle. The present invention does not require the implementation of articulated mattresses, solves problems, including cost of bedding to head and / or foot reclining known at present.

En outre, le dispositif selon la présente invention étant installable de manière amovible, il peut être utilisé alternativement sur plusieurs literies, voire même sur d'autres meubles tels que châssis de chaise longue. Furthermore, the device according to the present invention is installable in a detachable manner, it can be used alternately in several bedding, or even on other furniture such as deck chair frame.

Dans le premier exemple de réalisation, représenté à la figure 1, un dispositif 1 d'inclinaison de tête de lit est installé sur un lit 2 comprenant un sommier 3 et un matelas 4. Le sommier 3 est de type quelconque, pouvant être indifféremment à ressorts ou à lattes voire même plus simple encore. In the first embodiment, shown in Figure 1, a device 1 for headboard tilt is installed on a bed 2 including a beam 3 and a mattress 4. The frame 3 is of any type that can be indifferently springs or slats even simpler still. Est représentée sur la figure 1 la tête du lit 2. Is shown in Figure 1 the head of the bed 2.

Le dispositif 1 comprend deux moyens d'appui ou châssis articulés l'un sur l'autre. The device 1 comprises two support means or frames articulated to one another.

Le premier desdits moyens d'appui, formant base du dispositif, est constitué par un châssis dormant formé d'un boítier 7, de forme parallélépipédique allongée, et de deux tubes latéraux 9, partant de l'une et l'autre extrémité dudit boítier, par rapport auquel ils s'étendent perpendiculairement. The first of said support means, forming the base of the device is constituted by a chassis frame formed of a housing 7, elongated parallelepipedic shape, and two side tubes 9, starting from one and the other end of said housing with respect to which they extend perpendicularly.

Les deux tubes 9 s'étendent dans un même plan d'appui et sont destinés à reposer sur le sommier 3 comme on le voit sur la figure 1. Le boítier 7, lui, s'étend le long de l'extrémité du sommier, à l'extérieur de ce dernier de manière à ne pas gêner le matelas lorsque ce dernier s'étend à l'horizontale sur ledit sommier. The two tubes 9 extend in the same supporting plane and are intended to rest on the bed frame 3 as seen in Figure 1. The housing 7, it extends along the end of the bed, outside the latter so as not to impede the mattress when the latter extends horizontally on said base. Avantageusement, la face inférieure du boítier 7 s'étend dans le plan d'appui des deux tubes 9. De la sorte, le dispositif 1 peut servir au relevage et à l'inclinaison d'un matelas directement posé sur le sol. Advantageously, the underside of the housing 7 extends from the bearing plane of the two tubes 9. In this way, the device 1 can be used for lifting and tilting a mattress laid directly on the ground.

Le second moyen d'appui du dispositif 1 comprend un châssis mobile en forme de cadre 5, monté pivotant, au niveau de l'un de ses côtés 6, entre les extrémités libres des deux tubes 9, comme on le voit sur la figure 1. De la sorte, les châssis dormant et mobile du dispositif 1 s'étendent suivant deux plans d'appui formant un V d'ouverture réglable. The second support means of the device 1 comprises a movable frame-shaped frame 5, pivotably mounted at one of its sides 6, between the free ends of the two tubes 9, as seen in Figure 1 . in this way, the movable and fixed frame of the device 1 extend along two bearing planes forming a V adjustable opening. L'intérieur du cadre 5 est libre ou constitué par un treillis de fils métalliques (non représenté) adapté au soutien du matelas. Inside the frame 5 is free or consisting of a metal son grid (not shown) adapted to support the mattress.

Comme on le voit bien sur la figure 1, cet ensemble forme un plan d'appui adapté à maintenir une extrémité du matelas dans une position inclinée par rapport au reste dudit matelas qui s'étend à l'horizontale. As is seen in Figure 1, this assembly forms a support plane adapted to hold one end of the mattress in an inclined position relative to the remainder of said mattress extending horizontally.

A l'intérieur du boítier 7 est installé un moteur 16 maintenu par des flasques de support 15, ledit moteur se trouvant sensiblement au centre dudit boítier, à égale distance des tubes latéraux 9, par rapport auxquels son arbre 14 s'étend perpendiculairement. Within the housing 7 there is installed a motor 16 held by support flanges 15, said motor being substantially in the center of said housing, at equal distance of the side tubes 9, against which the shaft 14 extends perpendicularly. Comme on le voit sur la figure 1, cet arbre 14 s'étend de part et d'autre du moteur, ledit arbre 14 portant à ses extrémités deux pignons 13. Chacun de ces pignons 13 est en prise avec un pignon 12 se trouvant à l'extrémité d'une vis sans fin 11 logée à l'intérieur du tube latéral 9 se trouvant du côté correspondant. As seen in Figure 1, the shaft 14 extends on either side of the motor, said shaft 14 carrying at its ends two pinions 13. Each of these pinions 13 is meshed with a pinion 12 located at the end of a screw 11 housed inside of the side tube 9 located on the corresponding side.

A l'intérieur de chacun des tubes 9 coulisse un sabot mobile 10 dont le déplacement est commandé par la vis sans fin 11 correspondante. Within each of the tubes 9 slides a movable shoe 10 whose movement is controlled by the screw 11 corresponding. A ce sabot 10, dont une partie traverse le tube 9 au moyen d'une fente ménagée sur ce dernier, est associé un lever 8 dont une extrémité est montée pivotante sur ledit sabot. At this shoe 10, part of which passes through the tube 9 by means of a slot provided on the latter, is associated with a lever 8 having one end pivotally mounted on said shoe. L'autre extrémité de ce levier 8 est montée pivotante sur l'un des côtés latéraux du cadre 5. The other end of the lever 8 is pivotally mounted on one of the lateral sides of the frame 5.

Ainsi, au moyen de deux leviers 8 qui interviennent sur les côtés latéraux du cadre 5, le moteur 16 permet de commander l'écartement des deux châssis du dispositif 1, et, par conséquent, l'inclinaison de la tête de matelas. Thus, by means of two levers 8 which intervene on the lateral sides of the frame 5, the motor 16 is used to control the spacing of the two frames of the device 1, and therefore the inclination of the mattress head.

La figure 2 montre une variante de réalisation selon laquelle le dispositif d'inclinaison de tête de literie comprend toujours deux châssis constitués l'un par deux tubes latéraux 9 et l'autre par le cadre 5. Cette fois ci, cependant, le moteur 22 commandant l `écartement de ces châssis se trouve non plus entre les deux tubes 9 mais contre l'un de ces tubes, son arbre 21 s'étendant parallèlement à ces derniers, comme on le voit sur la figure 2. 2 shows an alternative embodiment according to which the existing head reclining device always comprises two frame constituted one by two lateral tubes 9 and the other by the frame 5. This time, however, the motor 22 Order the `spacing of these frames is located either between the two tubes 9 but against one of these tubes, its shaft 21 extending parallel to the latter, as seen in Figure 2.

Ce moteur 22, s'étendant à l'extérieur du sommier 3 le long de l'un des côtés latéraux de ce dernier, comporte, à l'extrémité de son arbre 21 un pignon 20 en prise avec un pignon 19 se trouvant à l'extrémité d'un arbre 18. L'arbre 18 possède en outre deux pignons 17 correspondant aux pignons 13 du précédent mode de réalisation. This motor 22, extending to the outside of the bed 3 along one of the lateral sides thereof, comprises, at the end of its shaft 21 a gear 20 engages a pinion 19 located at the end of a shaft 18. the shaft 18 also has two gears 17 corresponding to the pinions 13 of the previous embodiment. La transmission des efforts entre ces pignons 17 et les leviers 8 agissant sur le cadre 5 se fait comme dans l'exemple précédemment décrit. The transmission of forces between these pinions 17 and the levers 8 acting on the frame 5 is done as in the example described above.

Une troisième variante de réalisation, représentée à la figure 3, permet de commander simultanément les inclinaisons du pied et de la tête de literie. A third embodiment, shown in Figure 3, makes it possible to simultaneously control the inclination of the foot and bedding head.

La partie du dispositif intervenant en tête de lit peut être celle correspondant au premier ou au deuxième mode de réalisation qui viennent d'être décrits, à la différence que les vis sans fin 11 sont prolongées vers le pied de lit par des arbres 31 partant de boítiers 30 auxquels aboutissent lesdites vis 11, comme on le voit sur la figure 3. The part of the speaker device headboard can be that corresponding to the first or second embodiment described above, except that the endless screw 11 are extended to the footboard by shafts 31 extending from housings 30 which lead said screws 11, as seen in Figure 3.

Ces boítiers 30, pourvus d'un mécanisme de débrayage, permettent de solidariser et désolidariser à volonté chacune de ces vis sans fin 11 avec l'arbre 31 correspondant, dont une extrémité filetée forme également vis sans fin. These housings 30, provided with a release mechanism, possible to join and disconnect at will each screw 11 with the corresponding shaft 31, which also form a threaded end screw.

Avec cette partie filetée est en prise un sabot 32 qui commande un lever 23 agissant sur un second châssis mobile 24 dont un côté est monté pivotant entre des longerons 25 prolongeant les tubes 9, et à l'intérieur desquels sont logés les arbres 31. Ce second châssis mobile 24, articulé sur le châssis dormant 9 reposant sur le sommier 3, supporte le pied du matelas 4. With this threaded portion engages a shoe 32 which controls a lift 23 acting on a second moving frame 24 one side of which is pivotally mounted between side rails 25 extending the tubes 9, and inside which are housed the shafts 31. This second moving frame 24, hinged to the blind frame 9 resting on the beam 3, supports the foot of the mattress 4.

De la sorte, le moteur 16 peut commander, en plus de l'inclinaison de la tête de lit, celle du pied de lit. In this way, the motor 16 can be controlled, in addition to the tilt of the headboard, the footboard

Lorsque le mécanisme de débrayage est actionné pour désolidariser les arbres 31 des vis sans fin 11, la commande d'inclinaison de pied de lit est désactivée. When the release mechanism is operated to disengage the shafts 31 of the worm 11, the footboard tilt control is disabled. Autrement dit, on peut régler l'inclinaison de la tête de lit sans affecter celle de pied de lit, ce dernier gardant l'inclinaison qu'il avait avant débrayage. In other words, you can adjust the tilt of the headboard without affecting the footboard, the latter keeping the inclination he had before release.

En se reportant aux figures 4 à 7, un dispositif 101 selon l'invention est constitué d'un châssis dormant formé de deux tubes latéraux 109, de section ici rectangulaire, destinés à reposer sur le sommier, et d'un châssis mobile formé d'un cadre 105 en U monté pivotant sur et entre les tubes 109 du châssis dormant, grâce à des axes d'articulation 135. Referring to Figures 4 to 7, a device 101 according to the invention consists of a chassis frame formed of two side tubes 109, here of rectangular section, intended to rest on the bed frame, and a movable frame consisting of a frame 105 pivotally mounted on the U and between the tubes 109 of the fixed frame through the hinge 135 axis.

A l'intérieur de chacun des tubes 109 coulisse un sabot mobile 110 dont le déplacement est commandé par la vis sans fin 111 correspondante ; Within each of the tubes 109 there slides a movable shoe 110 whose movement is controlled by the screw 111 corresponding end; chaque sabot 110 présente, figure 7, un axe 148 qui traverse une fente 147, ménagée dans la paroi externe du tube 109, et autour duquel est articulé un lever 108 ; each shoe 110 has, FIG 7, an axis 148 which passes through a slot 147, formed in the outer wall of tube 109, and around which is hinged a lever 108; à son autre extrémité, chacun des leviers 108 se termine par une partie cintrée 134 à angle droit par laquelle il est monté articulé sur le cadre 105, ladite partie cintrée 134 prenant place dans un fourreau 149 solidarisé au cadre 105, par exemple par soudage. at its other end, each of the levers 108 ends in a curved portion 134 at right angles by which it is mounted articulated on the frame 105, said bent portion 134 takes place in a sleeve 149 secured to the frame 105, for example by welding.

Comme dans l'exemple décrit à propos de la figure 2, chaque vis sans fin 111 est munie à son extrémité d'un pignon 112 qui engrène chacun avec un pignon 117 porté par un arbre transversal 118 ; As in the example described with reference to Figure 2, each screw 111 is provided at its end with a pinion 112 which meshes with a pinion 117 each carried by a transverse shaft 118; l'arbre transversal 118 est en outre muni à une de ses extrémités d'un pignon 119 qui engrène avec le pignon 120 de l'arbre 121 d'un moteur 122 placé à l'extérieur du dispositif parallèlement à un tube latéral 109. the transverse shaft 118 is further provided at one of its ends with a pinion 119 which meshes with the pinion 120 of the shaft 121 of a motor 122 located outside of the device in parallel with a side tube 109.

Les extrémités des vis sans fin 111 et les pignons 112 qu'elles portent, d'une part, et les parties d'extrémité de l'arbre transversal 118 et les pignons 117 qu'elles portent, d'autre part, sont supportés par des carters 137 et 138 placés en bout des tubes latéraux 109 auxquels ils sont solidarisés ; The ends of the worm 111 and the pinions 112 they carry, on one hand, and the end portions of the transverse shaft 118 and the pinions 117 they carry, on the other hand, are supported by casings 137 and 138 placed at the end of the side tubes 109 to which they are joined; les extrémités des vis sans fin 111, opposées à celles qui portent les pignons 112, sont portées par des paliers de centrage 151 logés à l'intérieur des tubes latéraux 109 dont ils épousent la section interne quadrangulaire ; the ends of the worm 111, opposite those which carry the pinions 112, are carried by centering bearings 151 housed inside of the side tubes 109 they match the inner quadrangular section; avantageusement lesdits carters 137 et 138 sont reliés par un tube transversal 136 que traverse l'arbre transversal 118 ; advantageously said casings 137 and 138 are connected by a transverse tube 136 through which the transverse shaft 118; le moteur 122 et les pignons 119 et 120 sont placés dans un boítier 141 solidaire du tube latéral voisin 109 et du carter 137 par l'intermédiaire d'une plaque de fond 150. Le boítier 141 et les carters 137, 138 protègent l'extérieur des divers pignons et de la graisse qu'ils contiennent pour assurer leur longévité. the motor 122 and sprockets 119 and 120 are placed in a housing 141 secured to the adjacent side tube 109 and the housing 137 via a base plate 150. The housing 141 and the housings 137, 138 protect the outside various gears and fat they contain to ensure their longevity.

Selon une variante non représentée, les dimensionnements des pièces sont tels que les carters 137 et 138 sont constitués par des prolongements d'extrémités des tubes latéraux 109 associés à des bouchons d'extrémité. According to a variant not shown, the sizing of the parts are such that the housings 137 and 138 are formed by extensions of the ends of the side tubes 109 associated with end caps.

Comme on le voit, le dispositif 101 qui vient d'être décrit comporte un moyen de commande 122-120-119-117-111-118 libérant complètement l'intérieur du périmètre défini par les châssis ; As shown, the device 101 which has just been described comprises a 122-120-119-117-111-118 control means completely freeing within the perimeter defined by the frame; par ailleurs, la position complètement horizontale peut être obtenue : le cadre 105 s'inscrit à l'intérieur du périmètre du châssis dormant défini par les tubes latéraux 109 et le tube transversal 136, comme montré partiellement par les traits mixtes sur la figure 5, en sorte que dans la position des châssis complètement horizontale ceux-ci affleurent un même plan, tel que le plan P de la figure 6. Moreover, the completely horizontal position can be obtained: the frame 105 fits within the perimeter of the fixed frame defined by the side tubes 109 and the cross tube 136, as shown partially by dashed lines in Figure 5, so that in the position of the completely horizontal chassis thereof are flush with the same plane as the plane P of Figure 6.

Bien entendu, sans nuire au résultat recherché, le cadre 105 peut porter des lanières élastiques pour le support du matelas, telles que les lanières 146 de la figure 4. Of course, without affecting the desired result, the frame 105 may wear elastic straps to the mattress support, such as strips 146 of Figure 4.

Selon l'exemple décrit et représenté, la commande est motorisée : on comprend que les mêmes avantages sont obtenus avec une commande manuelle ; According to the example described and shown, the control is powered: it is understood that the same advantages are obtained with a manual control; ainsi, par exemple, les pignons étant solidarisés en rotation avec les arbres qui les portent par des méplats d'extrémité, tels que les méplats 139, 140 des arbres 118, 121 recevant les pignons 119, 120, il suffit de supprimer le moteur 122 et les pignons 119, 120 et d'entraíner les pignons 117 en faisant coopérer une manivelle avec les méplats 139 de l'arbre transversal 118. Thus, for example, the pinions being secured in rotation with the shafts which carry them by end flat surfaces, such as flats 139, 140 of shafts 118, 121 receiving the pinions 119, 120, it suffices to remove the motor 122 and the sprockets 119, 120 and cause the pinions 117 by engaging a crank with the flats 139 of the transverse shaft 118.

La figure 8 est analogue à la figure 6 mais montre une variante d'articulation de levier : ici, le levier 208 est droit, sans partie cintrée telle que 134, et est directement articulé sur l'extrémité d'un support d'axe 133 fixé au cadre 105. Figure 8 is similar to Figure 6 but shows a lever hinge variant: here, the lever 208 is right, without bent portion such as 134, and is directly articulated on the end of a support shaft 133 fixed to the frame 105.

Avantageusement, des moyens de fixation peuvent être prévus pour maintenir le dispositif sur le sommier. Advantageously, the attachment means may be provided for maintaining the device on the base. Il s'agit alors de moyens de fixation adaptés à des sommiers de type classique non spécialement prévus pour accueillir le dispositif. It is then fastening means adapted to conventional box springs not specifically designed to accommodate the device. De tels moyens de fixation peuvent, par exemple, comprendre des vis autoforeuses, notamment dans le cas des sommiers en bois, coopérant avec des pattes de fixation portées par le tube transversal 136, par exemple, telles que les pattes 142, 143 de la figure 4. Such attachment means may for example comprise self-tapping screws, especially in the case of wooden mattress supports, cooperating with fastening lugs carried by the cross tube 136, for example, such that the tabs 142, 143 of Figure 4.

Sur cette même figure 4, un autre moyen de retenue du dispositif a été illustré : ce moyen consiste en une bande transversale flexible 144 reliant les extrémités de prolongements 153 des tubes latéraux 109 ; In the same figure 4, another arrangement of the retaining means has been illustrated: this means consists of a flexible transverse strip 144 connecting the ends of extensions 153 of the side tubes 109; ces prolongements 153 ont une longueur suffisante pour que la bande 144 reçoive une partie du corps de la personne couchée qui ainsi exerce une poussée au droit de la bande 144 vers le sommier qui maintient le dispositif. these extensions 153 are of sufficient length so that the tape 144 is exposed a part of the body of the person lying thus pushes the right of the strip 144 to the bolster which holds the device.

Selon la figure 9, le maintien du dispositif est obtenu par une sangle 145 élastique faisant le tour par en dessous du sommier 3 et attelée par ses extrémités aux tubes latéraux 109 par des crochets 152. According to Figure 9, the maintenance of the device is obtained by an elastic strap 145 going around from beneath the beam 3 and coupled by its ends to the side tubes 109 by hooks 152.

Quoi qu'il en soit, quels que soient ces moyens de fixation ou de maintien, ils sont agencés en sorte que le dispositif est installé de manière amovible. Anyway, whatever these fastening or holding means, they are arranged so that the device is installed detachably.
