Definitions

  • the present invention relates to armchairs, in particular for outdoor use, in which the footrest, pivotally carried by the front edge of the seat, is connected to the articulated backrest on the base, so that any changing the backrest angle causes a corresponding change to that of the footrest.
  • This arrangement allows the footrest to angularly follow the orientation changes imparted to the backrest and the seat by the user, while allowing, by moving the axes in the arched lights, the complete folding of the seat.
  • the object of the invention is to allow the realization of an armchair of the aforementioned type which, while being of simple and robust construction, is capable of being folded up in a small footprint for its transport, its storage or its storage. .
  • the chair according to the invention is essentially remarkable in that the rear end of each of the longitudinal connecting rods which, in the usual way, provide the connection between the backrest and the footrest is articulated on a pivoting crankpin which is not angularly linked to said backrest only in one direction of rotation, so as to remain free to pivot in the opposite direction when folding the entire seat.
  • the reference 1 designates the seat base, the edges of which are articulated in 2 to the front legs 3 pivotally assembled in 5 to the rear legs 4 in order to define a base. foldable formed by two side struts braced, V-shaped open towards the ground.
  • the base of the reclining backrest 7 which is supported by the rear legs 4 by means of two studs 8 projecting (shown in fig. 4 in the form of simple axis lines) slidably engaged in slides 4 a .
  • each armrest 9 which is turned towards the bottom has a rack tooth clean to cooperate selectively with a fixed tooth provided on one or the other of the feet 3 or 4, above the assembly pivot 5 thereof.
  • the chair also includes a footrest 11 pivotally carried at 12 by the front edge of the seat 1.
  • Two longitudinal connecting rods 13 connect this footrest 11 to the backrest 7 so that any modification of the inclination of this the latter causes the tilting of said footrest which in the most straightened position of the backrest (fig. 1) is folded vertically below the seat 1, while in the inverted position of fig. 2 it is raised in the extension of this seat.
  • the connecting rods 13 must also allow the entire seat to be folded up in a small footprint (cf. fig. 5), with the footrest 11 brought parallel to the seat 1.
  • each connecting rod 13 connected to the opposite connecting rod by a cross member 13 a , is pivotally assembled at 14 to a crank pin 15 which in the embodiment envisaged crosses a lumen 1 a of the seat 1 to come articulate on the corresponding pivot 6, between the two ears 1 b of said seat which carry this pivot.
  • Each crankpin 15 is shaped to present a bearing or scope face 15 has adapted to cooperate with an upper stop 7 is provided on the back 7.
  • crank pins 15 and the backrest 7 and consequently between the latter and the footrest 11 also allows the folding of the chair in the manner illustrated in FIG. 5. Indeed, during this folding, the crank pins 15, until this time oriented substantially in the extension of the backrest 7, are free to pivot (angle ⁇ ) to come to orient themselves substantially perpendicular to the seat 1 and in the backrest 7, thereby authorizing the retraction of the connecting rods 13 and the complete folding of the footrest 11 which thus comes to orient itself parallel to the other elements of the seat.
  • crank pins 15 and their actuation by the backrest 7 in a single direction of pivoting may differ from those envisaged above, provided that a unidirectional angular connection is obtained.
