Definitions

  • the invention relates to a device for assembling the back of a chair on a supporting structure with a seat and less a tubular upright, the backrest having a tubular cavity intended to receive the upright, and a means of lock fitted with a retaining tooth intended to be clipped into a hole in the amount for blocking the latter.
  • the backrest is fixed to the supporting structure by at least two screw locking means.
  • the file is produced with two tubular housings on its rear part, vertically, and two uprights of support forming part of the supporting structure are introduced into these housing.
  • the file remains hung on the uprights, and, to prevent it from separates, it is blocked by screws or clips which pass through the housings and amounts at least partially.
  • the backrest is composed of two elements: a front panel, usually with a range and acting backrest, and a backrest that applies with the front panel.
  • an element has two tubular housings to receive the uprights file support.
  • the housings and the uprights are fixed together by added means such as screws or clips.
  • this operation always has the disadvantage of having to use fastening means and center the holes in which they are to be used.
  • the two elements of the file must be handled, stored and transported separately, being able to be assembled only after fixing of one of the two parts which applies to the support uprights.
  • Document D1 (US 2030635) describes a device for assembling the backrest of a chair on a supporting structure having a seat and at least one upright tubular, the backrest having a tubular cavity intended to receive the upright, and a locking means equipped with a retaining tooth intended to be clipped in a hole in the upright to block the latter.
  • the locking means consists of a pawl articulated around an axis, and urged towards the position of blocking by a return spring arranged at the opposite end with respect to the retaining spout. The mounting of the pawl remains a complicated operation.
  • the object of the invention is to provide a chair in which the assembly of the file with the support uprights is made with an original configuration and a combination of elements making it possible to exclude any means of attachment reported.
  • Another object is to provide a chair back composed by a back backrest and front panel which can be assembled before mounting on the structure, and therefore stored and transported together and at the same time.
  • the assembly thus proves to be easier and faster to perform with the advantage of a reduction labor costs.
  • the clip pins are arranged on the inner side of the backrest in contact with corresponding holes on the front panel.
  • FIG 1 there is shown the supporting structure 10 of a chair, provided with the seat 11 and having two tubular uprights 12 for supporting and blocking a backrest 13. A hole 14 is made on one side of each upright 12.
  • the backrest 13 is made up of two parts: a rear backrest 15 and a panel before 16, the latter being equipped with a gasket 16 '.
  • the backrest 15 is fitted with clip pins 17 on the inside, while the panel 16 is provided with holes 18 intended to receive by pressure these pins of clipping.
  • the rear folder 15 has two cavities 19 which extend vertically, each having a tubular structure intended to receive an upright 12.
  • a flexible vertical sleeve 20 provided at its top with a tooth 21.
  • the backrest 15 and the front panel 16 can be assembled beforehand by snap-fastening the clip pins 17 of one into the holes 18 the other.
  • the back 13 is then assembled to the uprights 12 of the chair in bringing these uprights into the corresponding tubular cavities 19, by using elasticity of sleeves 20, and sliding the backrest on the uprights up to trigger, by elastic reaction of these sleeves, the teeth 21 in the holes 14, as indicated in FIGS. 4, 4a and 5.
  • the backrest 13 When mounted, the backrest 13 is locked and cannot be moved to down from the top fin 23 and up from these same clip teeth 21.
