Definitions

  • the present invention relates to an armchair having a power-driven footrest with a pull-out extension.
  • armchairs having a footrest pivotally mounted in front of the base seat and powered for rotation between a lowered position and a raised position are known.
  • footrests incorporating an extension element to be drawn out before the foot rest.
  • the motor for rotation of the footrest also carries further crank mechanisms simultaneously controlling both the footrest rotation and the extension sliding.
  • This has disadvantages both in terms of costs (due to the crank mechanism complexity) and due to the fact that the footrest rotation is limited by the necessity of moving, by said rotation, the kinematic mechanism for the extension sliding.
  • the pulling-out amount of the extension is too tightly a function of the footrest rotation degree.
  • an armchair which comprises a power-driven footrest which is pivotally mounted for drivingly rotating between a lowered position and a raised position, the footrest at a free end thereof comprising an extension element movable between a retracted position and a position drawn out of the footrest for constituting lengthening thereof, characterized in that the extension element has a movement actuator between the two retracted and drawn-out positions, control means receiving a signal from a sensor for detection of the angular position of the footrest and operating the actuator for the extension element movement when the angular position is detected to be of a predetermined value.
  • an armchair generally identified by 10, comprises a footrest 11 pivotally mounted around an axis 12 for drivingly rotating between a lowered position and a raised position (shown in chain lines in the figure), relative to a base seat 13.
  • the footrest is driven by a motor 19 and at its free end comprises an extension element 14, movable between a retracted position and a position drawn out of the footrest for constituting lengthening thereof.
  • the armchair is not herein described in detail as it can be of any known type, as a person skilled in the art can easily envisage.
  • the armchair may comprise a back 15 also power-driven for controlled adjustment of the reclination.
  • Both the footrest motorization and, possibly, the back motorization are controlled by a control device 22 through commands sent for example from a keyboard 23, as known in the art.
  • the extension element 14 has an actuator 16 for movement between the two retracted and drawn-out positions (the last-mentioned position being shown in chain lines).
  • Control means 17 receives a signal from a sensor 18 for detection of the angular position of the footrest and operates the actuator for movement of the extension element when the angular position a is detected to be of a predetermined value.
  • the position sensor 20 may also be the limit switch itself signalling to the device 22 for footrest control that the position of maximum lifting has been reached.
  • the extension element is pulled out when a predetermined angular position of the footrest has been reached, which angular position can also be easily adjusted, without the existence of kinematic constraints given by the kinematic rotation mechanism of the footrest which is completely separated.
  • the kinematic mechanism for movement of the footrest can be any mechanism known in the art both of the type providing a direct rotation of the pivot axis and of the type providing movement transmission by crank mechanisms .
  • control device 17 may be incorporated into the control device 22 itself.

Abstract

Un fauteuil (10) comprend un repose-pied (11) à moteur, lequel est monté pivotant pour tourner de manière entraînée entre une position abaissée et une position relevée et inversement. Au niveau d'une extrémité libre, le repose-pied (11) comprend un élément d'extension (14) pouvant passer d'une position rétractée à une position étirée et inversement du repose-pied, afin de permettre son allongement. L'élément d'extension (14) comprend un actionneur (16) de mouvement entre les deux positions rétractées et étirées. Un moyen de commande (17) reçoit un signal d'un détecteur (18) détectant la position angulaire du repose-pied et il commande l'actionneur (16) mettant en mouvement l'élément d'extension (14) lorsque la position angulaire est détectée comme étant à une valeur prédéterminée. Avantageusement, le détecteur (18) est également un détecteur de limite du mouvement ascendant du repose-pied.
