  • the third fixed iron piece 10313 is fixed on the front beam 1031, and the driving plate 4011 is hinged to the third fixed iron piece 10313.
  • the drive plates 4011 are set in pairs
  • the drive links 4012 are set in pairs corresponding to the drive plates 4011
  • the paired drive plates 4011 pass through a drive shaft 4014
  • the driving part 4013 is connected with the driving shaft 4014, so that a driving part 4013 can drive a pair of driving connecting rods 4012 to move synchronously through a driving shaft 4014, so as to simplify the structure, which is the purpose of light weight and low cost of the product .
  • the driving link 4012 is also provided with a limit buffer pad 40121 that can be in contact with the first fixed iron piece 10311, through which the limit buffer pad 40121 limits the swing formation of the drive link 4012 and buffers the drive link.
  • the abutting force between the rod 4012 and the first fixed iron piece 10311 prevents damage to both.
  • the driver 4013 includes a second telescopic cylinder 40131, one end of the second telescopic cylinder 40131 is hinged to the driving plate 4011, and the other end is hinged to the bracket 1 , so as to drive the driving plate 4011 to rotate relative to the bracket 1 .
  • the bracket 1 also includes a connecting frame 10211 connected to the horizontal portion 1021, the connecting frame 10211 is hinged to one end of the second telescopic cylinder 40131, and the connecting frame 10211 is provided with a connecting hole for connecting the rotating shaft 1011 (not shown in the figure). ); thus, setting the connecting frame 10211 can reduce the difficulty of processing the bracket 1, and directly act on the rotating shaft 1011 by the force generated during the expansion and contraction of the second telescopic cylinder 40131.
  • the pedal rotation driving assembly 401 drives the first supporting plate 201 to rotate relative to the bracket 1
  • the driving rod 4024 drives the first connecting rod 4021 to rotate around the hinge position on the first supporting plate 201 through the conversion connection, thereby pulling the second connecting rod 4021
  • the rod 4022 makes the second support plate 202 move relative to the first support plate 201 to realize the extension or contraction of the pedal assembly 2.
  • the buffer assembly 4025 is set to drive the rod 4024 swings freely, and can also buffer its swing process, so that its drive is stable.
  • the seat of the present invention simplifies the linkage mechanism, the pedal structure and the bracket structure, has good economy, and has the advantages of light weight and low cost.

Abstract

La présente invention concerne un siège de loisir, se rapportant au domaine technique des sièges. Le siège de loisir selon la présente invention comprend : un support, un ensemble repose-pieds, et un mécanisme télescopique, l'ensemble repose-pieds comprenant une première plaque de support et une deuxième plaque de support, et la première plaque de support étant articulée avec le support. La première plaque de support comprend un corps de plaque et une plaque latérale formée par pliage d'un seul tenant du corps de plaque, et la deuxième plaque de support et la plaque latérale étant reliées de façon à pouvoir coulisser l'une par rapport à l'autre. Le mécanisme télescopique comprend un mécanisme de liaison de suivi et un ensemble d'entraînement de rotation de repose-pieds utilisé pour entraîner la première plaque de support en rotation par rapport au support, le mécanisme de liaison de suivi étant disposé entre la première plaque de support et la deuxième plaque de support pour entraîner le coulissement de la deuxième plaque de support. Dans le siège de loisir selon la présente invention, le corps de plaque de la première plaque de support est plié d'un seul tenant pour former une plaque latérale destinée à relier la deuxième plaque de support, ce qui simplifie la structure et réduit l'utilisation de pièces et ce qui rend le produit léger et à faible coût.
