The rails are closer on steeper slopes and this operates a support angle correction linkage which consists of an L shaped member (11) pivoted on the lower sliding bearing and attached with articulation (12) to the body and to the support by a rod (13) with articulated connections (14,15)

Description

La présente invention concerne un dispositif pour transporter des personnes ou des charges dans un escalier présentant des pentes différentes et/ou des virages, comprenant deux rails de guidage fixés l'un au-dessus de l'autre le long de l'escalier, un bâti déplaçable le long des rails de guidage, un support monté sur le bâti et destiné à recevoir au moins une personne ou une charge, des moyens d'entraínement pour déplacer le bâti le long des rails de guidage, et des moyens de correction d'assiette pour maintenir le support horizontalement quelle que soit la pente de l'escalier.The present invention relates to a device for transporting people or loads on a staircase with slopes different and / or turns, including two guide rails fixed one above the other along the stairs, a frame movable along the guide rails, a support mounted on the built and intended to receive at least one person or a load, drive means for moving the frame along the rails guidance, and attitude correction means to maintain the support horizontally whatever the slope of the staircase.

Les dispositifs conçus actuellement pour transporter des personnes ou des charges dans un escalier présentant des pentes différentes comportent des moyens de correction d'assiette compliqués, difficiles à réaliser et coûteux.The devices currently designed to transport people or loads on a staircase with slopes different include attitude correction means complicated, difficult to carry out and expensive.

La présente invention se propose plus particulièrement d'apporter une solution à ce problème et, pour ce faire, elle a pour objet un dispositif de transport ayant la structure indiquée ci-dessus et caractérisé en ce que les moyens de correction d'assiette comprennent une première articulation assurant une liaison pivotante entre le support et le bâti, deux rotules supérieures déplaçables le long du rail de guidage supérieur et sur lesquelles est fixé le bâti, une rotule inférieure déplaçable le long du rail de guidage inférieur, un bras coudé fixé au niveau de son coude sur la rotule inférieure, une deuxième articulation assurant une liaison pivotante entre l'extrémité libre de l'une des branches du bras coudé et le bâti, et une bielle reliée au support par une troisième articulation et à l'extrémité libre de l'autre branche du bras coudé par une quatrième articulation, toutes les articulations étant horizontales et parallèles entre elles.The present invention more particularly proposes to provide a solution to this problem and, to do this, it has for object a transport device having the structure indicated above and characterized in that the attitude correction means include a first articulation ensuring a pivoting connection between the support and the frame, two movable upper ball joints along the upper guide rail and on which the frame, a lower ball joint movable along the guide rail lower, an arm bent fixed at the level of its elbow on the patella lower, a second articulation ensuring a pivoting connection between the free end of one of the branches of the bent arm and the frame, and a connecting rod connected to the support by a third articulation and at the free end of the other branch of the arm bent by a fourth joint, all the joints being horizontal and parallel to each other.

Ces moyens de correction d'assiette ont une structure simple, ce qui permet de les réaliser et de les assembler facilement tout en limitant le prix de revient du dispositif de transport.These attitude correction means have a simple structure, which allows them to be made and assembled easily while limiting the cost price of the transport device.

De préférence, les rails de guidage sont fixés sur des montants répartis le long de l'escalier et pourvus de colliers de serrage dans chacun desquels est immobilisée une tige de fixation solidaire du rail de guidage correspondant. Preferably, the guide rails are fixed on uprights distributed along the stairs and fitted with cable ties in each of which is fixed an integral fixing rod the corresponding guide rail.

Le positionnement des rails de guidage l'un par rapport à l'autre peut ainsi être réalisé rapidement et avec précision puisqu'il suffit de fixer les colliers de serrage à la hauteur adéquate sur les montants.The positioning of the guide rails with respect to the other can thus be carried out quickly and precisely since it suffices to fix the cable ties to the height adequate on the uprights.

Selon un mode de réalisation préféré, les montants sont répartis le long d'un mur portant l'escalier et s'étendent entre le mur et les rails de guidage, le bâti, le support, le levier coudé et la bielle étant situés du côté opposé au mur par rapport aux rails de guidage.According to a preferred embodiment, the amounts are distributed along a wall carrying the staircase and extend between the wall and guide rails, frame, support, bent lever and the connecting rod being located on the side opposite the wall with respect to the rails guide.

Par ailleurs, chacune des rotules comporte de préférence un corps annulaire pourvu d'une cavité comportant une surface de forme sphérique, ainsi qu'une bague logée dans la cavité et apte à pivoter dans celle-ci dans tous les sens, cette bague comportant une surface externe de forme sphérique s'appuyant contre la surface de la cavité et une surface interne cylindrique s'appuyant contre le rail de guidage associé, le corps annulaire et la bague de chaque rotule étant respectivement pourvus de fentes conformées pour livrer passage aux tiges de fixation du rail de guidage correspondant lors du déplacement du bâti.Furthermore, each of the ball joints preferably comprises a annular body provided with a cavity having a shaped surface spherical, as well as a ring housed in the cavity and able to pivot in it in all directions, this ring having a surface external spherical shape leaning against the surface of the cavity and a cylindrical internal surface pressing against the rail of associated guide, the annular body and the ring of each ball joint being respectively provided with slots shaped to deliver passage to the corresponding guide rail fixing rods during displacement of the frame.

Pour permettre le transport de personnes, le support est de préférence pourvu d'un siège comportant un plan de symétrie vertical s'étendant perpendiculairement à la direction de transport.To allow the transport of people, the support is preferably provided with a seat having a vertical plane of symmetry extending perpendicular to the direction of transport.

Un mode d'exécution de la présente invention sera décrit ci-après à titre d'exemple nullement limitatif en référence aux dessins annexés dans lesquels:

  • la figure 1 est une vue de face schématique d'un escalier présentant des pentes différentes et pourvu d'un dispositif de transport conforme à l'invention ;
  • la figure 2 est une vue de côté de l'escalier et du dispositif visible sur la figure 1 ;
  • la figure 3 est une vue de face schématique partielle et agrandie du dispositif de transport selon l'invention, cette vue étant prise dans la direction opposée au mur visible sur les figures 1 et 2 et représentant le dispositif de transport dans une partie de l'escalier ayant une pente déterminée ;
  • la figure 4 est une vue prise dans la même direction que sur la figure 3 mais montrant le dispositif de transport dans une partie horizontale de l'escalier ;
  • la figure 5 est une vue analogue à celle représentée sur la figure 3, mais montre le dispositif de transport dans une partie de l'escalier plus pentue que dans la partie visible sur la figure 3 ; et
  • la figure 6 est une vue en perspective schématique d'une rotule faisant partie des moyens de correction d'assiette du dispositif de transport.
An embodiment of the present invention will be described below by way of nonlimiting example with reference to the accompanying drawings in which:
  • Figure 1 is a schematic front view of a staircase having different slopes and provided with a transport device according to the invention;
  • Figure 2 is a side view of the staircase and the device visible in Figure 1;
  • Figure 3 is a partial schematic enlarged front view of the transport device according to the invention, this view being taken in the direction opposite to the wall visible in Figures 1 and 2 and showing the transport device in part of the staircase with a determined slope;
  • Figure 4 is a view taken in the same direction as in Figure 3 but showing the transport device in a horizontal part of the staircase;
  • Figure 5 is a view similar to that shown in Figure 3, but shows the transport device in a part of the staircase more steep than in the visible part in Figure 3; and
  • Figure 6 is a schematic perspective view of a ball joint forming part of the attitude correction means of the transport device.

L'escalier visible sur la figure 1 s'étend à partir d'un palier inférieur A et comprend successivement une première partie B ayant une pente déterminée, une deuxième partie C s'étendant horizontalement et une troisième partie D ayant une pente plus importante que celle de la partie B.The staircase visible in Figure 1 extends from a landing lower A and successively comprises a first part B having a determined slope, a second part C extending horizontally and a third part D having a steeper slope important than that of part B.

Il est équipé d'un dispositif de transport installé le long d'un mur M et permettant de déplacer des personnes âgées ou handicapées.It is equipped with a transport device installed along a wall M and allowing the elderly or disabilities.

Ce dispositif de transport comprend tout d'abord un rail de guidage supérieur 1 et un rail de guidage inférieur 2 fixé sous le rail supérieur 1.This transport device firstly comprises a rail of upper guide 1 and a lower guide rail 2 fixed under the top rail 1.

Ces rails s'étendent le long de l'escalier et sont séparés l'un de l'autre par des distances différentes selon la partie de l'escalier dans laquelle ils se trouvent. Plus précisément, leur distance est la plus grande dans la partie horizontale C et la plus faible dans la partie D, laquelle est plus pentue que la partie B.These rails extend along the stairs and are separated one on the other by different distances according to the part of the stairs they are on. More specifically, their distance is greatest in the horizontal part C and the most weak in part D, which is steeper than part B.

Comme le montrent les figures 3 à 5, le dispositif de transport comprend également un bâti 3 déplaçable le long des rails de guidage 1, 2, un support 4 monté sur le bâti 3 et sur lequel est fixé un siège 5, des moyens d'entraínement conventionnels 6 pour déplacer le bâti 3 le long des rails, et des moyens de correction d'assiette 7 maintenant horizontalement le support 4, et par conséquent le siège 5, quelle que soit la pente de l'escalier.As shown in Figures 3 to 5, the transport device also includes a frame 3 movable along the guide rails 1, 2, a support 4 mounted on the frame 3 and on which is fixed a seat 5, conventional drive means 6 for moving the frame 3 along the rails, and trim correction means 7 holding the support 4 horizontally, and consequently the seat 5, whatever the slope of the stairs.

On notera que les moyens d'entraínement 6, qui ne sont visibles que sur les figures 1 et 3, comprennent un moteur électrique 6a destiné à entraíner en rotation un galet 6b prenant appui contre le rail supérieur 1.Note that the drive means 6, which are not visible that in Figures 1 and 3, include an electric motor 6a intended to rotate a roller 6b bearing against the top rail 1.

Dans le mode de réalisation représenté, les moyens de correction d'assiette 7 comprennent une première articulation 8 assurant une liaison pivotante entre le support 4 et le bâti 3, deux rotules supérieures 9 déplaçables le long du rail de guidage supérieur 1 et sur lesquelles est fixé le bâti 3, une rotule inférieure 10 déplaçable le long du rail de guidage inférieur 2, un bras coudé 11 fixé au niveau de son coude sur la rotule inférieure 10, une deuxième articulation 12 assurant une liaison pivotante entre l'extrémité libre de la branche 11a du bras coudé 11 et le bâti 3, et une bielle 13 reliée au support 4 par une troisième articulation 14 et à l'extrémité libre de la branche 11b du bras coudé par une quatrième articulation 15.In the embodiment shown, the means of attitude correction 7 include a first articulation 8 ensuring a pivoting connection between the support 4 and the frame 3, two upper ball joints 9 movable along the guide rail upper 1 and on which the frame 3 is fixed, a ball joint lower 10 movable along the lower guide rail 2, a bent arm 11 fixed at its elbow on the lower ball joint 10, a second articulation 12 ensuring a pivoting connection between the free end of the branch 11a of the bent arm 11 and the frame 3, and a connecting rod 13 connected to the support 4 by a third articulation 14 and at the free end of the branch 11b of the arm bent by a fourth articulation 15.

on précisera ici que les articulations 8, 12, 14 et 15 sont horizontales et parallèles entre elles.it will be specified here that the joints 8, 12, 14 and 15 are horizontal and parallel to each other.

Par ailleurs, les rails de guidage 1, 2 sont fixés sur des montants verticaux 16 répartis le long de l'escalier et pourvus chacun de deux colliers de serrage 17 dans chacun desquels est immobilisée une tige de fixation 18 solidaire du rail de guidage correspondant.Furthermore, the guide rails 1, 2 are fixed on vertical uprights 16 distributed along the stairs and provided each of two clamps 17 in each of which is immobilized a fixing rod 18 secured to the guide rail corresponding.

Dans le mode de réalisation représenté, les colliers 17 comportent deux vis 19 permettant d'ajuster la position des colliers le long des montants lorsqu'elles sont dévissées et d'immobiliser les colliers dans les positions adéquates lorsqu'elles sont visées.In the embodiment shown, the collars 17 have two screws 19 for adjusting the position of the collars along the uprights when they are unscrewed and immobilize collars in the correct positions when targeted.

En se référant à la figure 2, on remarquera par ailleurs que les montants 16 s'étendent entre le mur M et les rails de guidage 1, 2, tandis que le bâti 3, le support 4, le levier coudé 11 et la bielle 13 sont situés du côté opposé au mur M par rapport aux rails de guidage, c'est-à-dire du côté de la partie de l'escalier qui est empruntée par les personnes.Referring to Figure 2, it will also be noted that the uprights 16 extend between the wall M and the guide rails 1, 2, while the frame 3, the support 4, the bent lever 11 and the connecting rod 13 are located on the side opposite the wall M with respect to the rails guide, i.e. on the side of the part of the staircase which is borrowed by people.

En se référant maintenant à la figure 6, on pourra constater que les rotules 9 et 10, qui sont toutes identiques, comportent un corps annulaire 20 pourvu d'une cavité 21 comportant une surface de forme sphérique, ainsi qu'une bague 22 logée dans la cavité 21 et apte à pivoter dans celle-ci dans tous les sens, la bague 22 comportant une surface externe de forme sphérique s'appuyant contre la surface de la cavité 21 et une surface interne cylindrique s'appuyant contre le rail de guidage associé.Referring now to Figure 6, we can see that ball joints 9 and 10, which are all identical, have a annular body 20 provided with a cavity 21 comprising a surface of spherical shape, as well as a ring 22 housed in the cavity 21 and suitable for pivoting therein in all directions, the ring 22 having a spherical outer surface resting against the surface of the cavity 21 and a cylindrical internal surface leaning against the associated guide rail.

Le corps annulaire 20 et la bague 22 des rotules sont respectivement pourvus de fentes 23, 24 conformées pour livrer passage aux tiges de fixation 18 des rails de guidage 1, 2 lors du déplacement du bâti 3 le long de ceux-ci.The annular body 20 and the ring 22 of the ball joints are respectively provided with slots 23, 24 shaped to deliver passage to the fixing rods 18 of the guide rails 1, 2 during the displacement of the frame 3 along these.

on notera ici que la fente 23 du corps annulaire 20 permet d'introduire très facilement la bague 22 dans la cavité 21. Il suffit en effet de placer la bague 22 perpendiculairement au corps 20 et de l'introduire dans la fente de celui-ci, puis de la faire pivoter de façon que sa surface externe vienne contre la surface de la cavité.it will be noted here that the slot 23 of the annular body 20 allows very easily introduce the ring 22 into the cavity 21. It it suffices to place the ring 22 perpendicular to the body 20 and insert it into the slot thereof, then make it rotate so that its outer surface comes against the surface of the cavity.

Pour être complet, on précisera que le siège 5 présente un plan de symétrie vertical s'étendant perpendiculairement à la direction de transport. Il est d'un type connu en soi et ne sera donc pas décrit.To be complete, it will be specified that seat 5 has a plan of vertical symmetry extending perpendicular to the direction transport. It is of a type known per se and therefore will not described.

Bien entendu, si le dispositif de transport selon l'invention devait être utilisé pour transporter non plus des personnes mais des charges particulières, il conviendrait bien entendu de remplacer le siège 5 par un réceptacle approprié.Of course, if the transport device according to the invention was to be used to transport not people but particular loads, it would of course be necessary to replace the seat 5 by an appropriate receptacle.

Les figures 3 à 5 montrent clairement les positions relatives des éléments constitutifs des moyens de correction d'assiette 7 dans les parties B, C et D de l'escalier.Figures 3 to 5 clearly show the relative positions constituent elements of the attitude correction means 7 in parts B, C and D of the staircase.

Ainsi, la bielle 13 s'incline progressivement vers la droite lorsque le support 4 se déplace de la partie C à la partie B, puis de la partie B à la partie D. Le bras coudé 11 pivote quant à lui progressivement dans le sens de la flèche F représenté sur la figure 4.Thus, the connecting rod 13 gradually tilts to the right when the support 4 moves from part C to part B, then from part B to part D. The bent arm 11 pivots meanwhile gradually in the direction of arrow F shown in the figure 4.

Les figures 3 à 5 montrent également que le siège 5 reste horizontal quelle que soit la position du support 4 dans l'escalier.Figures 3 to 5 also show that seat 5 remains horizontal whatever the position of the support 4 on the stairs.

Il ressort de ce qui précède que le dispositif de déplacement selon l'invention comporte des moyens de correction d'assiette particulièrement simples et permettant à la personne installée sur le siège 5 de monter ou descendre l'escalier en toute sécurité, quelles que soient les variations d'inclinaison que ce dernier peut présenter.It appears from the above that the displacement device according to the invention includes attitude correction means particularly simple and allowing the person installed on seat 5 to go up or down the stairs safely, whatever the tilt variations that the latter can present.
