Abstract

The lifting apparatus includes a vertical mast (1) with a specific profile. A carrier moves on the pole by rotation. A chassis (7) has two arms (8) linked to it so as to be able to move around two axes. Each arm has two wheels (11) on it. A device allows independent motorised movement on the ground. The motorised device includes an omni directional wheel, a motor and a battery. An attachment device allows liquid or powder containers to be attached to the mast. A tape device attached to the mast moves along with the carrier.

Description

L'invention est relative à un ensemble lève-malades perfectionné du genre comportant généralement :

  • un mât vertical, au profil spécifique, dans lequel se déplace, entraîné par une vis sans fin animée d'un mouvement de rotation réversible, un chariot pourvu d'un porte-options qui s'étend à l'extérieur dudit mât au travers d'une fente longitudinale pourvue d'un moyen d'étanchéité;
  • une embase, à ouverture motorisée, constituée par un châssis et deux bras articulés autour de deux axes solidaires dudit châssis.
The invention relates to an improved patient lift assembly of the kind generally comprising:
  • a vertical mast, with a specific profile, in which moves, driven by an endless screw animated by a reversible rotational movement, a carriage provided with an option carrier which extends outside said mast through 'a longitudinal slot provided with a sealing means;
  • a base, with motorized opening, constituted by a chassis and two arms articulated around two axes integral with said chassis.

Dans les ensembles connus du genre en question :

  • le moyen d'étanchéité du mât, généralement du type à brosses ou à languettes en matière caoutchouteuse, manque d'efficacité et est d'un entretien difficile;
  • le moyen d'ouverture motorisée des bras articulés est généralement réalisé à partir d'un ensemble "motoréducteur-moyen de liaison aux bras articulés" autonome introduisant un coût supplémentaire d'acquisition et d'entretien;
  • aucun moyen de déplacement motorisé de l'ensemble n'est prévu.
In known sets of the genus in question:
  • the sealing means of the mast, generally of the type with brushes or tabs made of rubbery material, is ineffective and is difficult to maintain;
  • the motorized opening means of the articulated arms is generally produced from an autonomous "gearmotor-means of connection to the articulated arms" introducing an additional cost of acquisition and maintenance;
  • no means of motorized movement of the assembly is provided.

L'invention vise donc à réaliser un ensemble lève-malades dans lequel on a cherché :

  • à améliorer l'étanchéité du mât pour une meilleure exploitation de l'appareil dans les services hospitaliers à soins intensifs et dans les services d'hydrothérapie;
  • à utiliser l'énergie existante au niveau de la vis sans fin pour permettre l'ouverture motorisée des bras articulés pour un meilleur accès à différents types de supports (fauteuils, chaises-toilettes...);
  • à faire réaliser un profil dont la section intérieure intégre divers dispositifs de positionnement et de guidage des sous-ensembles en mouvement dans le mât voire se prolongeant à l'extérieur;
  • à permettre le déplacement motorisé dans toutes les directions de l'ensemble de manière à accroître les possibilités d'utilisation dudit ensemble (déambulation assistée par exemple);
  • à rechercher des solutions simples et économiques pour les divers moyens sus-exposés ainsi que pour la réalisation des pieds (modulaires emboîtables et non en mécano-soudure) et des assises (en mousse thermo-compressée) des diverses options.
The invention therefore aims to produce a patient lift assembly in which we sought:
  • to improve the tightness of the mast for better use of the apparatus in hospital intensive care services and in hydrotherapy services;
  • to use the existing energy at the level of the worm to allow the motorized opening of the articulated arms for better access to different types of supports (armchairs, chair-toilets ...);
  • to make a profile whose internal section integrates various positioning and guiding devices of the moving sub-assemblies in the mast or even extending outside;
  • allow motorized movement in all directions of the assembly so as to increase the possibilities of using said assembly (assisted walking for example);
  • to seek simple and economical solutions for the various means mentioned above as well as for the realization of the feet (modular interlocking and not in mechanical welding) and seats (in thermo-compressed foam) of the various options.

Elle concerne à cet effet :

  • un moyen d'étanchéité du mât, aux projections de liquides et aux poussières de toutes sortes, qui est réalisé à partir d'un ruban, se déplaçant en même temps que le chariot, venant obturer la fente longitudinale dudit mât au dessus et au dessous du porte-options lors de son déplacement vertical vers le bas ou vers le haut en fonction du sens de rotation de la vis sans fin;
  • un moyen d'ouverture motorisée des bras articulés qui est réalisé à partir de la vis sans fin verticale qui comporte, à son extrémité inférieure, un dispositif de liaison assurant l'accouplement débrayable de cette dernière à un moyen apte à provoquer l'écartement angulaire desdits bras articulés et leur retour à la position initiale où ils sont paralléles entre eux;
  • un mât dont la section comporte, intérieurement, essentiellement, des parois de guidage des roues du chariot, une ouverture de guidage de la poignée de manipulation dudit ensemble et une fente de guidage et de maintien du ruban d'étanchéité;
  • un moyen autonome de déplacement de l'ensemble, placé à la verticale du mât, qui comporte un ensemble "roue omnidirectionnelle (20)-motoréducteur(21)-batterie (22)" apte à permettre le déplacement motorisé de l'ensemble lève-malades.
To this end, it concerns:
  • a means of sealing the mast, against liquid projections and dust of all kinds, which is produced from a tape, moving at the same time as the carriage, closing the longitudinal slot of said mast above and below the options carrier during its vertical movement down or up depending on the direction of rotation of the worm;
  • motorized opening means of the articulated arms which is produced from the vertical endless screw which comprises, at its lower end, a connecting device ensuring the disengageable coupling of the latter to a means capable of causing angular separation said articulated arms and their return to the initial position where they are mutually parallel;
  • a mast, the section of which comprises, internally, essentially, guide walls of the wheels of the carriage, an opening for guiding the handling handle of said assembly and a slot for guiding and holding the sealing tape;
  • an independent means of movement of the assembly, placed vertically above the mast, which comprises an assembly "omnidirectional wheel (20) -motor gearbox (21) -battery (22)" capable of allowing motorized movement of the lift assembly- sick.
