Definitions

  • the object of this invention is a folding chair with an articulating device of plate type shaped in such a way as to allow full nesting of the legs of the chair in the closed position.
  • a folding chair comprising two pairs of legs and a seat, articulated to one another, in which there is located between the front legs and rear legs an articulating device having one end rotationally integral with the rear leg and the opposite end rotationally integral with a fixed member projecting transversally from the rear face of the front leg, means also being provided for arresting the rotation of such articulating device in relation to the opposite positions of opening and closure.
  • such articulating device consists of a plate of substantially "H" shape the opposite ends of which form housings to accommodate the upper ends of the rear legs, and of a member integral with the front legs, respectively. Furthermore, at such ends containing the fixed member there is provided a cavity extending lengthwise towards the inside of the plate and capable of accommodating such locking device, which preferably consists of a latch located inside the plate and capable of cooperating with the relevant recesses in such transverse member under the thrust action exerted in an axial direction by flexible components, such recesses being arranged in a counterposed manner along an axis parallel to the longitudinal axis of the front legs in order to effect locking in relation to the sole positions of full opening and full closure.
  • such locking device is comprised of a latch projecting transversally from the front leg and capable of being inserted by spring action into a corresponding housing of the articulating plate, or for such plate to be held against the front leg in the positions of full opening and full closure by means of devices of magnetic type.
  • the chair according to the invention is essentially comprised of a supporting frame with a first member 1 consisting of two parallel plates 1a made integral with a transverse member 1b, also of plate type, and carrying at their upper end the opposite ends of a arched back 2.
  • first member 1 and second member 3 of the frame thus constitute the articulated legs of the chair - front legs 1a and rear legs 2a, respectively - to which is made rotationally integral, by means of pins or the like which are self-evident and not shown in the figures, seat 4.
  • the device for relative articulation of the legs consists of a plate 5 of substantially "H" shape the opposite ends of which form two housings 5a and 5b respectively extending lengthwise towards the inside of body 5, housing 5a being furthermore shaped with internal transverse side 5c located in an inclined position to allow relative rotation of rear leg 2a as will be described in greater detail hereinafter.
  • a cavity 6 to accommodate a spring 8 acting on a latch 9 capable of cooperating with corresponding recessed housings 7a provided, in counterposed positions, on the surface of a transverse member 7 projecting transversally from the rear surface of front leg 1a, to which it is attached, for example by means of screws, providing means for locking plate 5 in relation to front leg 1a.
  • transverse through holes 5d capable of accommodating appropriate pins 6a providing a rotary link between plate 5 and rear leg 2a and plate 5 and transverse member 7.
  • the hole has one of its ends countersunk to accommodate the head of a flathead screw, not illustrated, the threaded end of which is engaged in nut 5e.
  • Figure 4a shows the relative setting of the various parts with the chair in an open condition: legs 1a are inclined according to a certain appropriate angle; plate 5 is set against legs 1a with latch 9 pushed by spring 8 against upper recessed housing 7a of cross-member 7 and with the rear legs correspondingly inclined to the rear.
  • the counteraction of latch 9 maintains in a locked condition the relative positions of the various components to prevent accidental and undesired closure of the chair.
  • plate 5 is also made of magnetic material in order to obtain adherence to front leg 1a and ensure stability in the open and closed positions.
  • provision may also be made for applying magnetic pads located in appropriate housings machined into the plate and the legs to obtain the same effect of adherence described above.
