Description

Domaine de l'inventionField of the invention

L'invention se rapporte à des dispositifs de sécurité facilitant la montée et la descente d'escaliers et prévenant par ailleurs les chutes.The invention relates to safety devices facilitating the rise and fall of stairs and also preventing falls.

L'invention est destinée plus particulièrement à permettre à des personnes toujours capables de se déplacer mais présentant des difficultés de mobilité ou d'équilibre de se servir sans danger d'escaliers.The invention is intended more particularly to allow people still able to move but having mobility or balance difficulties to safely use stairs.

Description du problèmedescription of the problem

La plupart des immeubles à étage sont mal conçus pour des personnes présentant des problèmes de mobilité, quelle que soit l'origine de leurs problèmes : accident, maladie, problèmes liés à l'âge.Most two-storey buildings are poorly designed for people with mobility problems, regardless of the source of their problems: accident, illness, age-related problems.

Un changement d'environnement n'est pas une solution, surtout pour des personnes âgées qui perdent ainsi leurs repères. Par ailleurs, lorsque le handicap est mineur, de telles personnes se refusent à envisager des aménagements lourds, qui leur apparaissent comme une atteinte à leur dignité. On a donc cherché à développer un dispositif d'un usage aisé, conférant une bonne sécurité lors du passage d'un étage à un autre via un escalier préexistant.A change of environment is not a solution, especially for seniors who are losing their bearings. Moreover, when the disability is minor, such people refuse to consider heavy development, which they see as an attack on their dignity. It has therefore sought to develop a device for easy use, giving good security when passing from one floor to another via a pre-existing staircase.

On connaît des « ascenseurs d'escaliers » comportant un siège, généralement repliable, muni d'un moteur électrique progressant sur une rampe montée sur le côté des marches d'un escalier existant. On connaît aussi, pour des personnes plus gravement handicapées, des plates-formes basées sur le même principe permettant à des personnes en voiturette de remonter un escalier."Stair lifts" are known having a seat, generally folding, provided with an electric motor progressing on a ramp mounted on the side of the steps of an existing staircase. We also know, for people with more severe disabilities, platforms based on the same principle allowing people by cart to go up a staircase.

État de la techniqueState of the art

De nombreux dispositifs ont déjà été développés pour assurer un utilisateur dans un escalier. GB 2 218 344 décrit un harnais de sécurité accroché à un câble muni éventuellement d'un contrepoids. US 1 785 487 décrit une barrière mobile se déplaçant le long de deux rampes. D'autres systèmes décrivent une barre horizontale coulissant le long d'une rampe courant parallèlement à l'escalier. Cette rampe peut être munie d'un système d'arrêt, qui est généralement une crémaillère ou un système d'encoches ( GB 2 188 344 , US 2007/0017170 , US 4 253 287 ), voire d'un système d'arrêt débrayable ( GB 2 257 723 ). Suivant une autre conception, la barre d'appui est munie d'un système de freinage ( US 4 899 989 , DE 2006 012 433 ).Many devices have already been developed to ensure a user in a staircase. GB 2 218 344 describes a safety harness hooked to a cable possibly equipped with a counterweight. US 1,785,487 describes a movable barrier moving along two ramps. Other systems describe a horizontal bar sliding along a running ramp parallel to the stairs. This ramp may be provided with a stop system, which is generally a rack or a system of notches ( GB 2,188,344 , US 2007/0017170 , US 4,253,287 ), or even a disengageable stop system ( GB 2,257,723 ). According to another design, the support bar is provided with a braking system ( US 4,899,989 , DE 2006 012 433 ).

These and other aspects of the invention will be clarified in the detailed description of particular embodiments of the invention, with reference to the drawings of the figures, in which:
  • Fig.1 is a schematic side view of a user going up a staircase using an embodiment of the device according to the invention.
  • Fig.2 is a face of the device, the arms being raised.

Les figures ne sont pas dessinées à l'échelle. Généralement, des éléments semblables sont désignés par des références semblables dans les figures.The figures are not drawn to scale. Generally, similar elements are designated by similar references in the figures.

Description détaillée des figuresDetailed description of the figures

La Figure 1 montre le principe de fonctionnement de l'invention : l'utilisateur 1 est accompagné, tant à la montée (comme représenté ici) qu'à la descente par un bloc-moteur 2 monté sur un rail 4 courant parallèlement à la volée d'escalier 6. Ce bloc-moteur 2 supporte deux bras 8, 10 disposés sensiblement à hauteur de la taille de l'usager 1. Celui-ci dispose de commandes (décrites plus loin) lui permettant d'assigner au dispositif différentes fonctions suivant qu'il est plus ou moins ingambe.The Figure 1 shows the operating principle of the invention: the user 1 is accompanied, both on the ascent (as shown here) and on the descent by an engine block 2 mounted on a rail 4 running parallel to the flight of stairs 6. This engine block 2 supports two arms 8, 10 disposed substantially to the height of the user's size 1. It has commands (described later) allowing it to assign the device different functions depending on whether it is more or less ingambe.

Le dispositif permet, suivant un premier usage, d'assumer simplement une protection contre les chutes à l'utilisateur en bonne condition physique. Dans ce cas, l'utilisateur règle la vitesse du dispositif sur son propre pas, assuré, en cas de faux pas ou d'étourdissement, de ne pas tomber, maintenu qu'il est par les barres de protection disposées à la hauteur de sa taille.The device allows, according to a first use, to simply assume a fall protection to the user in good physical condition. In this case, the user sets the speed of the device on his own step, ensured, in case of missteps or dizziness, not to fall, maintained that it is by the protective bars arranged at the height of his cut.

Suivant une deuxième "philosophie d'usage", le dispositif procure à un utilisateur en condition physique "moyenne" ou médiocre, et notamment en phase de réadaptation post-traumatique, un appui et une aide effectifs. Il peut ainsi réapprendre à marcher normalement, et bénéficier à la fois d'un soutien et d'une véritable aide à la marche.According to a second "philosophy of use", the device provides a user in "average" or poor physical condition, including post-traumatic rehabilitation, effective support and assistance. He can relearn how to walk normally, and benefit from both support and real walking aids.

Suivant une troisième "philosophie d'usage", le dispositif permet à un utilisateur en mauvaise condition physique de continuer à utiliser un escalier, lui procurant ainsi un exercice salutaire, sans risque pour lui, et en lui offrant à la fois une sécurité absolue et un soutien physique, le bloc-moteur fournissant dans ce cas une grande partie de l'effort nécessaire à la montée.According to a third "philosophy of use", the device allows a user in poor physical condition to continue using a staircase, thus providing him a healthy exercise, without risk for him, and offering him both absolute security and a physical support, the engine block providing in this case much of the effort required to climb.

Le présent dispositif permet aussi à certaines personnes qui hésiteraient à dépendre d'un ascenseur d'escalier de continuer à habiter un logement non-adapté à leurs difficultés physiques.The present device also allows some people who would hesitate to depend on a stair lift to continue to live in a housing not adapted to their physical difficulties.

La Fig. 2 montre, plus en détail, un mode de réalisation du dispositif suivant l'invention.The Fig. 2 shows, in more detail, an embodiment of the device according to the invention.

Les deux bras 8, 10 fixés sur le bloc-moteur 2 sont représentés relevés, ce qui permet d'utiliser l'escalier normalement, le bloc-moteur 2, de faible encombrement, ne gênant pas l'accès à l'escalier.The two arms 8, 10 fixed on the engine block 2 are shown raised, which allows the use of the staircase normally, the engine block 2, small footprint, does not interfere with access to the stairs.

Le bloc-moteur 2, muni ici d'une alimentation embarquée 12 (une batterie rechargeable) est enfermé dans une carrosserie 14 de forme appropriée, qui prévient tout contact dangereux avec une pièce mobile et est muni d'un dispositif de transmission engrenant sur le rail 4, voire sur un double rail garantissant une parfaite verticalité au système.The engine block 2, here provided with an onboard power supply 12 (a rechargeable battery) is enclosed in a body 14 of appropriate shape, which prevents any dangerous contact with a moving part and is provided with a transmission device meshing on the rail 4, or even on a double rail guaranteeing a perfect verticality to the system.

L'entraînement du bloc-moteur 2 peut se faire via un moteur agissant sur une crémaillère 16, comme illustré, mais aussi par contact glissant, ou par un système de câbles disposés en va-et-vient, etc. L'alimentation du moteur peut se faire via un câble électrique, via un rail en alimentation Basse Tension, via la batterie embarquée, etc. Dans le cas d'une batterie embarquée, au moins un poste d'alimentation est prévu, soit en haut, soit en bas de l'escalier, afin que la batterie 12 puisse se recharger entre deux utilisations. Un bouton d'appel (non représenté) permet de faire monter ou descendre le dispositif à la demande. La batterie 12 peut également alimenter un diffuseur muni de diodes lumineuses à très faible consommation éclairant les marches 6 pendant la montée/la descente.The drive of the engine block 2 can be done via a motor acting on a rack 16, as illustrated, but also by sliding contact, or by a system of cables arranged back and forth, etc.. The motor can be supplied via an electric cable, via a low voltage supply rail, via the on-board battery, etc. In the case of an on-board battery, at least one power station is provided, either at the top or at the bottom of the staircase, so that the battery 12 can be recharged between two uses. A call button (not shown) makes it possible to raise or lower the device on demand. The battery 12 can also power a diffuser provided with very low consumption light diodes illuminating the steps 6 during the rise / fall.

Les deux bras 8, 10 sont symétriques, de façon à pouvoir servir indifféremment de bras antérieur et/ou de bras postérieur à la montée ou à la descente. Ils sont montés à pivotement sur un dispositif de fixation 18 solidaire du bloc-moteur 2. Le dispositif de fixation permet 18 de régler à la fois la hauteur des bras 8, 10 et leur écartement. Ces bras sont munis d'un rembourrage 20 destiné à répartir la pression exercée sur le tronc de l'utilisateur en cas de chute.The two arms 8, 10 are symmetrical, so that they can be used indifferently for the front arm and / or the rear arm for the ascent or descent. They are pivotally mounted on a fastening device 18 integral with the engine block 2. The fastening device 18 makes it possible to adjust both the height of the arms 8, 10 and their spacing. These arms are provided with a padding 20 for distributing the pressure exerted on the trunk of the user in the event of a fall.

Chaque bras 8, 10 peut être abaissé en position active (horizontale) distinctement l'un de l'autre. De façon optionnelle, l'abaissement d'un bras ou la saisie du bras antérieur 8 provoque l'abaissement automatique de l'autre bras 10, via un mécanisme à retardement qui peut être pneumatique ou électrique. Quelle que soit l'option choisie, un dispositif de sécurité 21 empêche la mise en branle du dispositif tant que les deux bras 8, 10 n'ont pas été abaissés en place et que l'utilisateur n'est pas fermement assuré. Le dispositif de sécurité 21 est par ailleurs muni d'un circuit de mesure conçu de façon à arrêter le moteur en cas de résistance anormale à l'avancement ou de chute de l'utilisateur, et ce jusqu'à ce qu'une décision soit prise par l'utilisateur lui-même ou par une tierce personne.Each arm 8, 10 can be lowered into the active (horizontal) position distinctly from each other. Optionally, the lowering of one arm or the gripping of the front arm 8 causes the automatic lowering of the other arm 10, via a delay mechanism which can be pneumatic or electric. Whichever option is chosen, a safety device 21 prevents the device from moving until the two arms 8, 10 have been lowered in place and the user is not firmly ensured. The safety device 21 is also provided with a measuring circuit designed to stop the motor in case of abnormal resistance to the advancement or fall of the user, and until a decision is taken by the user himself or by a third person.

La partie des bras venant en contact avec le torse de l'utilisateur est munie d'un rembourrage 20 afin de répartir la pression exercée sur le corps en cas de chute et pour offrir un appui confortable aux avant-bras.The portion of the arms engaging the wearer's torso is provided with padding 20 to distribute the pressure exerted on the body in the event of a fall and to provide comfortable support for the forearms.

L'extrémité 22 des bras 8, 10 est incurvée de façon à éviter toute chute latérale.The end 22 of the arms 8, 10 is curved so as to avoid any lateral drop.

Les commandes sont disposées sur un arceau 24 distal décalé vers l'avant et incliné par rapport au plan horizontal suivant un angle α étudié pour que les mains de l'utilisateur se posent naturellement à hauteur des commandes 26, 28 lorsque ses avant-bras reposent sur le rembourrage 20 de la barre d'appui 8.The controls are arranged on a distal arch 24 offset forwards and inclined relative to the horizontal plane at an angle α designed so that the user's hands naturally land at the height of the controls 26, 28 when his forearms rest. on the padding 20 of the support bar 8.

En serrant les mains sur l'arceau de commande 24, l'utilisateur actionne deux barrettes de contact 26, 28 qui constituent à la fois un dispositif de mise en route et une sécurité d'"'homme-mort" : dans ce cas, il est impératif que les deux barrettes 26, 28 soient actionnées simultanément pour que le dispositif se mette en marche. On peut également prévoir qu'une alarme se déclanche au cas où les barrettes de contact 26, 28 sont relâchées pendant un temps prédéterminé.By shaking hands with the control bar 24, the user actuates two contact bars 26, 28 which constitute both a starting device and a safety "dead man": in this case, it is imperative that the two bars 26, 28 are operated simultaneously for the device to start. It can also be provided that an alarm is triggered in the case where the contact strips 26, 28 are released for a predetermined time.

L'utilisateur dispose également d'un bouton d'alarme 30 disposé centralement sur l'arceau de commande. Ce bouton d'alarme peut, suivant le cas, actionner une sonnerie ou encore déclencher un signal à distance pour appeler des secours.The user also has an alarm button 30 arranged centrally on the control bar. This alarm button can, as the case may be, activate a bell or trigger a remote signal to call for help.

Un curseur 32 placé sur le bloc-moteur 2 permet de régler la vitesse de déplacement de l'appareil le long du rail 4. On peut éventuellement coupler ce réglage à un système manuel de contrôle fin, dépendant par exemple de la force exercée sur une des barrettes de commande 26, 28.A slider 32 placed on the engine block 2 makes it possible to adjust the speed of movement of the apparatus along the rail 4. This adjustment may optionally be coupled to a manual fine control system, depending, for example, on the force exerted on a machine. control strips 26, 28.

Le rail de guidage 4 peut, au choix, être fixé sur un mur ou sur l'escalier 6 lui-même. Les fixations doivent évidemment être suffisamment résistantes pour supporter le poids de l'usager en cas de chute.The guide rail 4 may, as desired, be fixed on a wall or on the stairs 6 itself. The fasteners must obviously be strong enough to support the weight of the user in case of a fall.

Le rail 4 doit évidemment être conçu de façon à être adaptable à tout type d'escalier : droit, courbé, à palier, etc.The rail 4 must obviously be designed to be adaptable to any type of staircase: straight, curved, landing, etc.

Suivant une forme de réalisation avantageuse, le dispositif de l'invention peut être conçu de façon à s'adapter à un système de rail 4 préexistant, de façon à permettre une installation "évolutive". De cette façon, en cas d'aggravation de l'état de l'utilisateur, le rail 4 voire même le bloc-moteur 2 peut être réutilisé pour l'installation d'un siège conventionnel.According to an advantageous embodiment, the device of the invention can be designed to adapt to a pre-existing rail system 4, so as to allow a "scalable" installation. In this way, in case of worsening of the user's condition, the rail 4 or even the engine block 2 can be reused for the installation of a conventional seat.
