Definitions

  • the invention relates to a chair with a seat plate, a supporting base frame and a backrest, with the following features:
  • the underframe comprises two U-shaped lateral side parts with front and rear legs, each connected by a horizontal bottom part;
  • Chairs of this type are known. These are usually relatively lightweight chairs that can be stackable and / or provide the ability to form contiguous rows of chairs.
  • the base of such chairs consists for example of a rod material made of steel or another metal.
  • the legs are made on the sides of the chair by contiguous structures of the aforementioned bar material, which are suitably joined from side to side.
  • the bar stock used usually made of steel, is usually elastically bendable. This flexibility can be used to give the chair at least certain suspension properties and in particular to make the backrest with respect to the seat plate resiliently.
  • the invention is therefore based on the object to provide a chair of the type mentioned, which has suspension properties that at least partially automatically adapt to the weight of the user of the chair.
  • the chair according to the invention is characterized by the following features:
  • the bent-over upper ends of the front legs of the two side panels carry a first transverse axis directed transversely to the chair underneath
  • the bent upper ends of the rear legs of the two side parts carry a second transversely directed to the chair transverse axis below the seat plate;
  • the second transverse axis is at a distance behind the first transverse axis
  • the backrest is based on a lever which extends from behind under the seat plate and from the front to the front first receives the second and then the first transverse axis pivotally.
  • the backrest can rebound significantly as the user of the chair leans back.
  • the first, front axle is raised and lowered that of the rear legs.
  • the seat plate With the first, from the front legs outgoing transverse axis, the seat plate is raised. In this way, the weight of the user of the chair can counteract the retraction of the backrest. The heavier the user, the more the backrest is supported by its weight. This results in an automatically controllable suspension effect for the backrest.
  • the lever extends beyond the first, front transverse axis beyond the seat plate.
  • a spring for example in the form of a rubber buffer, is placed between the end of the lever and the underside of the seat panel.
  • Such a spring serves as a return spring, as it exerts a preload on the lever.
  • the front and rear axles may be formed by angling the upper ends of the front and rear legs bent back under the seat plate at their outer ends of the bent portions again so as to be from the right and left sides on the left side coaxially towards each other. In this way, they can form two-part axes or they can be connected physically. This results in a considerable stabilization of the chair as a whole.
  • the upper bent ends of the front legs are fixedly connected to the underside of the seat plate, so that the bending ability of the bent upper ends of the front legs can also provide a certain suspension effect.
  • a spring element such as a body made of an elastomeric material or a metal spring.
  • the spring element serves as a return spring for the backrest. Since the front end of the lever protrudes beyond the first transverse axis, it approaches the underside of the seat plate in the illustrated lever movement, so that when a compression spring is inserted between the front end of the lever and the underside of the seat plate, a bias toward the starting position the chair elements is generated.
  • Fig. 1 is a side view of a chair according to the invention.
  • Fig. 2 shows a plan view of the base of the chair with the seat plate omitted.
  • Fig. 1 is a side view of a chair according to the invention seen from the right side.
  • a seat plate is designated 10 and a backrest 12.
  • the seat plate rests on a base 14.
  • Information such as right side, left side, front and rear relate in this context to the sitting position of a user, not shown, on a chair. In this sense, Fig. 1 shows a view of the right side of the chair.
  • a right side part 16 is shown.
  • the side part 16 is made of rod material, for example of steel. It is bent in a U-shape and accordingly comprises a front leg 18, a rear leg 20 and a bottom, the legs 18,20 connecting, lying horizontally on the floor bottom part 22nd
  • the upper ends of the legs 18, 20, which are indicated at 24, 26, are bent in the horizontal direction in the direction under the seat plate 10 and toward each other.
  • the side part 16 forms in this way an almost completely closed rectangular frame, which is not physically connected only in the upper area below the seat plate.
  • transverse transverse axes 28,30 which are naturally perpendicular to the plane in Fig. 1.
  • the transverse axes 28, 30 can be fastened to the bent-over ends 24, 26 in mutually corresponding, opposite positions.
  • the two transverse axes 28,30 take a lever 32 which extends from the back of the seat plate 10 forth under the seat plate.
  • the lever 32 carries the backrest 12, which rises behind the seat plate. He takes the two transverse axes 28,30 and is pivotally mounted with respect to this. 1 When the user of the chair leans back and on the backrest
  • lever 32 has an end 34 which extends forwards over the two transverse axes 28, 30 and in particular also the front transverse axis 28.
  • This end 34 of the lever 32 is supported on the underside of the seat plate 10 l ⁇ , or, the seat plate 10 rests on the front end 34 of the lever
  • the seat plate 10 is connected to the bent upper ends 24 of the front case 5 ne 18, so that the seat plate 10 in addition by these bent upper ends 24 experiences a slightly elastic support.
  • Fig. 2 the bent-over upper ends of the front leg 0 18 and the rear leg 20, as in Fig. 1, 24,26 designated.
  • the respective corresponding parts on the opposite, so left side of the chair bear the same reference numerals with the addition of a line.
  • the opposite bent portions 28,28 'and 30,30' are aligned with each other and thus extend coaxially, so that they can serve as an axis common 5. They therefore together form the two transverse axes 28,30.
  • the angled ends 28, 28 'and 30, 30' can also be connected to one another to form a common axis, as shown in FIG. 2.
  • the lever is indicated in Fig. 2 only dash-dotted lines. He takes on the two axes 28,30 and carries in the rest in his behind the seat plate 10 projecting portion 36, the towering backrest 12th
