Definitions

  • This invention relates to collapsible or folding chairs having a rigid seat.
  • Folding chairs are already known in which the two front legs are interconnected and prolonged into the back of the chair, these front legs being rotatably connected to two rear legs which cross the front legs and are also interconnected.
  • the rear legs support at their tops the front part of the seat of the chair which, at the rear, is supported by the front legs by means of pivots or similar members.
  • connection between the lower part of the back and the rear edge of the seat is a firm hinge connection, which the connection between the rear leg frame and the front edge of the seat is a slit hinge connection.
  • This allows simultaneous turning and sliding between pairs of legs and the seat in the longitudinal axis of the latter.
  • the pivots in the leg frame act jointly with slits or similar devices arranged at the seat along its longitudinal axis so that, upon folding the pairs of legs, the seat will occupy a position along the common plane of the folding pairs of legs. In this way the folded chair will take up comparatively little space.
  • the seat upon the folding up of the chair, strikes against the chair back so that the panels on the back will ordinarily prevent the seat from folding completely into the frame formed by the back and side legs unless the side stringers of the frame are abnormally thick or unless the transverse panels of the back are positioned at such a height as to afford space underneath for the folded seat. Consequently the folded chair will occupy a comparatively large space, and will be unhandy when a number of chairs are arranged in a pile, as the seat which protrudes to a greater or less extent from the chair frames will get in the way.
  • the slit hinge connection is arranged as a connection between the seat and the front leg frame, so that the rear part of the seat, when the chair is folded, will slide downwardly and inwardly against the front leg frame.
  • Figure 1 shows a chair in front view in unfolded state
  • Figure 6 a detail of the chair shown in section and larger scale.
  • the seat 3 of the chair has on its underside two side stringers i!) which at their front parts, by means of pivots II, are fastened to revolve with the upper ends of rear-legs 2, the side stringers having on their outer side slots 9 into which engage round pivots 8 fastened on the inner sides of front-legs I.
  • the pivot 3 abuts the rear end of slot -9 and thus prevents the legs from sliding further.
  • the slot 9 slides along the pivot 8, the seat simultaneously tip-ping more and more backwards, until it finally, together with rear-legs 2, folds into the space formed by the frame of the front-legs.
  • the side stringers l0, Figure 6 will be embedded in the U-shaped mounting I which is rigidly fastened to the front-legs l and fastened to revolve with respect to the rear-legs 2 by means of a bolt not shown.
  • the rear-legs 2 may be bent at an angle, in order to fit in the best possible manner into the space at disposal between the front-legs.
  • a folding chair as defined in claim 1, wherein said side stringers are U-shaped in cross-section having grooves formed therein which face the inner sides of the adjacent portions of said front legs, said grooves cooperating with said pivotal connection between said side stringers and said front legs.
