Abstract

The conversion of the furniture article between bed and chair configurations and vice versa is actuated by an electric jack (9). There is an articulation (5) pivoted at three points (6-8) to allow the adjustment of the armrests (4) into a position as an extension of the back of the chair (1) during movement to a horizontal configuration. It produces a vertical movement in the rests during tilting of the assembly around the rotary cross axis (5) which is permanently parallel to the support frame to allow the movement of the armrests to a horizontal position.

Description

La présente invention concerne un fauteuil-brancard permettant un transport et une manutention aisée des patients du fauteuil au lit et du lit au fauteuil. Ce dispositif est destiné à facilité le travail des personnels hospitaliers et à assurer un plus grand confort aux patients en leur évitant des efforts inutiles.The present invention relates to a stretcher chair allowing easy transport and handling of patients from the chair to the bed and from the bed to the chair. This device is intended to facilitate the work of hospital staff and to provide greater comfort to patients by avoiding unnecessary efforts.

Cette manutention s'effectue actuellement par des systèmes de lève personnes électriques nécessitant l'emploi de sangles. Ces systèmes n'étant destinés qu'au transfert du patient, le transport est assuré par des fauteuils de type classique uniquement conçus pour le transport.This handling is currently carried out by electric lift systems requiring the use of straps. These systems being intended only for the transfer of the patient, the transport is ensured by armchairs of conventional type only designed for transport.

Des fauteuils de transfert électriques sont également utilisés pour la manutention des patients. Ces systèmes qui n'adoptent pas la double position fauteuil et brancard, n'admettent pas de fonctionnement uniquement mécanique du fauteuil. Le patient dans ce système est contraint de s'asseoir sur le siège de transfert.Electric transfer chairs are also used for patient handling. These systems which do not adopt the double position armchair and stretcher, do not admit only mechanical functioning of the armchair. The patient in this system is forced to sit on the transfer seat.

L'invention, le fauteuil-brancard, consiste en un fauteuil pouvant adopter une
position de brancard (horizontale) par un basculement de l'ensemble de la
structure. Ce basculement, qui met en jeu une articulation spécifique du
fauteuil (éléments (4) et (5)), peut être assuré soit par un moteur électrique
(9), soit mécaniquement. Le basculement mécanique de la structure est alors
facilité par des poignées mobiles (11) situées au bout des accoudoirs du
fauteuil. Ainsi, le patient s'étant glissé de son lit au fauteuil en position
horizontale (brancard) et l'opérateur hospitalier ayant bloqué l'assise du siège
grâce à la goupille de blocage (13), une légère traction du patient, grâce aux
poignées mobiles (11), permet le passage de la position horizontale
(brancard) à la position verticale (fauteuil). Le patient peut alors être
transporté en fauteuil en utilisant les poignées de déplacement (12).
The invention, the stretcher chair, consists of a chair that can adopt a
stretcher position (horizontal) by tilting the entire
structure. This tilting, which involves a specific articulation of the
armchair (elements (4) and (5)), can be provided either by an electric motor
(9), either mechanically. The mechanical tilting of the structure is then
facilitated by movable handles (11) located at the end of the armrests of the
armchair. Thus, the patient having slipped from his bed to the chair in position
horizontal (stretcher) and the hospital operator who blocked the seat
thanks to the locking pin (13), a slight traction of the patient, thanks to the
movable handles (11), allows the passage from the horizontal position
(stretcher) in the vertical position (chair). The patient can then be
transported in a wheelchair using the movement handles (12).

L'articulation spécifique qui comporte les éléments (4) et (5) permet un parfait alignement des bras et du dossier du fauteuil sur un plan horizontal (position brancard). Ainsi, le passage du patient du lit au fauteuil ne se trouve pas entravé par les bras du fauteuil.The specific articulation which includes elements (4) and (5) allows perfect alignment of the arms and back of the chair on a horizontal plane (stretcher position). Thus, the patient's passage from the bed to the chair is not hindered by the arms of the chair.

With reference to these drawings, the stretcher chair includes
- a file (1)
- seat of the armchair (2)
- movable leg rest (3)
- armrests (4)
- specific articulation system (5)
- fixing point (6)
- fixing point (7)
- fixing point (8)
- electric motor (9)
- mobile support for the seat of the chair (10)
- movable handles at an angle of 360 "(11)
- a specific joint made up of elements 4 and 5
- movement handles to steer the chair (12)
- wheelchair seat locking pin (13)
- transverse axis no 14 (14)
- transverse axis of rotation No 15 (15)
- axis n "16 (16)
The entire frame of the chair can be made of steel or light and resistant materials. The armchair includes a rectangular frame on which are fixed 4 movable wheels allowing to move and direct the armchair.

L'ensemble de l'articulation du fauteuil peut être mise en oeuvre par un vérin électrique (9) qui exerce une traction ou une poussée sur l'axe transversal n" 14 (14) suivant la position recherchée (horizontale ou verticale). L'ensemble du siège (dossier et assise) bascule alors autour de l'axe transversal de rotation n" 15 (15) permettant l'obtention de la position horizontale (brancard) ou verticale (fauteuil). Lors de cette rotation autour de l'axe de rotation n"15 (15) l'ensemble de l'articulation constituée par les accoudoirs et le système articulé n"5 permet un mouvement verticale des accoudoirs. Ces derniers restent alors en permanence parallèle au châssis porteur. Pendant toute la durée de la rotation les accoudoirs restent en position horizontale. En fin de rotation le dossier et les accoudoirs sont situés dans le même alignement et se trouve sur le même plan parallèle au châssis porteur (position horizontale). Les accoudoirs du fauteuil sont alors totalement escamotés permettant au patient de se glisser sans entrave du lit sur le fauteuil en position horizontale. The whole articulation of the chair can be implemented by an electric actuator (9) which exerts a traction or a push on the transverse axis n "14 (14) according to the desired position (horizontal or vertical). the entire seat (backrest and seat) then swings around the transverse axis of rotation no. 15 (15) allowing the horizontal (stretcher) or vertical (armchair) position to be obtained. During this rotation around the axis of rotation n "15 (15) the whole of the articulation constituted by the armrests and the articulated system n" 5 allows a vertical movement of the armrests. The latter then remain permanently parallel to the carrying frame. Throughout the duration of the rotation the armrests remain in a horizontal position. At the end of rotation, the backrest and the armrests are located in the same alignment and are on the same plane parallel to the supporting frame (horizontal position). The armrests of the chair are then completely retracted allowing the patient to slide unhindered from the bed onto the chair in a horizontal position.

Une position intermédiaire peut être obtenue en faisant basculer l'assise du siège autour de l'axe n" 15 (15). Pour obtenir cette position il faut débloquer l'assise (2) en retirant la goupille de blocage (13). Le support mobile de l'assise du siège (10) peut alors atteindre une position maximale en bout de course autour de l'axe n"16 (16). Cette position maximum permet une position intermédiaire de l'assise du siège (position semi allongée).En l'absence de vérin électrique le mouvement de rotation autour de l'axe transversal de rotation n"15 (15) peut être obtenu mécaniquement et sans grands efforts.An intermediate position can be obtained by tilting the seat base around the axis no. 15 (15). To obtain this position, the seat (2) must be released by removing the locking pin (13). movable support for the seat cushion (10) can then reach a maximum position at the end of its travel around the axis n "16 (16). This maximum position allows an intermediate position of the seat cushion (semi-extended position). In the absence of an electric actuator the rotation movement around the transverse axis of rotation no. 15 (15) can be obtained mechanically and without great efforts.

L'opérateur bascule alors manuellement le fauteuil vers l'arrière tandis que le patient, grâce aux poignées mobiles (11) exerce une traction vers l'arrière facilitant ainsi le basculement du fauteuil autour de l'axe n0 15. Le fauteuil se retrouve alors en position verticale.The operator then manually tilts the chair backwards while the patient, thanks to the movable handles (11) exerts a rearward pull thus facilitating the tilting of the chair around axis No. 15. The chair is then found upright.

L'assise et le dossier du fauteuil sont recouvert d'un revêtement en mousse pour le confort du patient. Cette mousse peut être recouverte par tout revêtement (tissu, cuir, etc...). The seat and back of the chair are covered with a foam covering for patient comfort. This foam can be covered by any coating (fabric, leather, etc.).
