Definitions

  • the invention relates to seating, in particular a stackable chair, according to the preamble of patent claim 1.
  • the object of the present invention is therefore to remedy these disadvantages of the prior art of silver furniture, in particular chairs.
  • a piece of silver furniture, in particular a stackable chair is to be created which is easier to handle and enables less force-consuming, back-friendly stacking.
  • the chair should be as compact and space-saving as possible.
  • the chair should have the lightest possible construction and be simple and inexpensive to manufacture.
  • the solution to these problems consists in seating, in particular in a stackable chair, which has the features stated in the characterizing section of patent claim 1. Further developments and / or advantageous embodiment variants of the invention are the subject of the dependent claims.
  • the invention proposes that, in the case of a piece of seating furniture, in particular in the case of a stackable chair, with a seat shell mounted in a carrier frame and having a seat recess and a back part, the seat shell is pivotably articulated in the carrier frame.
  • the seat shell can be swung out of a sitting position into a stacking position in which a free front edge of the seat recess occupies a lower position than in the seat position.
  • the carrier frame has a larger clear width in a front section closer to the free front edge of the seat recess than in a rear section.
  • the swivel mounting allows the seat shell to be swiveled out of a sitting position into a stacked position.
  • a front section of the carrier frame which is closer to the free front edge of the seat recess has a larger clear width than a rear section. This means that the chairs can be pushed together and stacked one behind the other, laterally. It is no longer necessary to lift each chair. If the surface is suitable, the chairs can be easily pushed into one another with the seat shell swung down.
  • the trough-shaped seat shell of the rear chair accommodates the seat shell of the front chair.
  • the wider front section of the support frame of the rear chair overlaps the rear section of the support frame of the front chair on the outer sides thereof.
  • the seat shell is suspended from two suspension points in the support frame, which are each arranged in the side parts of the seat shell.
  • the shape of the seat shell of the chair and its elongation is designed such that when the seat shell is pivoted away, its center of gravity lies approximately in a plane that is spanned by the two suspension points of the seat shell and the direction of gravity. As a result, the swung-out seat shell takes up a hurried, stable position which does not require any special fixation via stops or the like.
  • the seat shell is made from a separate seat recess and a separate back part.
  • the two parts are preferably connected to one another only at the two lateral suspension points and can be pivoted together.
  • the seat recess and the back part can be pivoted relative to one another to a limited extent and can be fixed in the respective position. This constructive measure allows the chair to be adapted to the individual needs of a person taking a seat on it.
  • the detachable swivel mechanism is provided at the two suspension points. It comprises a flange part with detachable recesses that is detachably connected to the support frame, a rotating part that is connected to the seat shell and that extends through the flange part, and a coupling part that can be displaced axially relative to the flange against a spring force. Locking teeth protrude from the circumference of the coupling part, which engage in recesses of the rotating part and can be locked in the latching recesses of the flange part.
  • the coupling part has three locking teeth, which are preferably distributed uniformly over the circumference, which engage in recesses of the rotating part and can be locked in at least two different triple rings of locking recesses of the flange part that belong together.
  • the at least two triple blocks of latching recesses belonging together define the seating position and the pivoting-down position of the seat shell. This means that the seat shell can also be clearly fixed in the swiveled position. This makes stacking the chairs even easier.
  • the spring-loaded coupling part also forms a push button for releasing the locking mechanism for pivoting the seat shell.
  • the push button does not protrude from the inside of the seat shell facing the user and can be operated from the inside.
  • the chair is designed as a so-called cantilever chair.
  • the support frame is formed in one piece and has a bracket with two support arms with a stand frame.
  • the stand frame forms an acute angle with the support arms. In this way it is ensured that the center of gravity vector of the chair runs approximately in the middle section of the stand frame, so that the chair has a secure stand and cannot tip over even in the normally loaded state.
  • the chair By arranging wheels, rollers or the like at the transition of the support arms to the stand frame, the chair can be easily moved. This further simplifies the lateral stacking of the chairs and their transportation.
  • the support frame comprises a front and a rear pair of chair legs.
  • the front pair of chair legs has a larger clear width than the outside distance of the rear pair of chair legs.
  • the chairs overlaps the front pair of legs of the higher chair on the outside of the rear pair of legs of the front chair. This enables space-saving, compact stacking.
  • a front and a rear chair leg are arranged inclined to one another on both sides of the seat shell in such a way that they form the legs of a triangle.
  • the suspension points for the seat shell are arranged approximately at the intersection of the two chair legs.
  • the front or rear pair of chair legs or both pairs of chairs can be provided with rollers or wheels.
  • the chairs are largely independent of the surface and can be easily moved, in particular pushed together, without exerting a great deal of effort.
  • Figure 1 shows a first embodiment of a stackable chair with a seat shell in the sitting position.
  • FIG. 2 the chair from FIG. 1 with the seat shell in the stacking position
  • FIG. 3 shows a number of laterally stacked chairs according to FIG. 2; 4 shows a variant of a stackable chair with the seat shell pivoted away;
  • FIG. 5 shows a number of laterally stacked chairs according to FIG. 4.
  • Fig. 6 is an exploded view of a pivot mechanism.
  • a first exemplary embodiment of a stackable chair designed in accordance with the invention is provided overall with the reference number 1 in FIGS. 1 and 2.
  • the chair comprises a seat shell 5 which is mounted in a support frame 2.
  • the support frame 2 is composed of a front and a rear pair of chair legs 3 and 4.
  • the front pair of chair legs 3 has a larger internal clearance than the outside distance of the rear pair of chair legs 4.
  • a front chair leg 3 and a rushed rear chair leg 4 each form an acute angle with one another and form the legs of a triangle.
  • the pivot point for the seat shell 5, at which a pivot mechanism 10 is provided for the seat shell, is located approximately at the tip of the triangle formed in this way.
  • the seat shell 5 is trough-shaped and comprises a seat trough 6 with a free front edge 7 and a back part 8.
  • the front and rear chair legs 3, 4 are equipped with wheels, rollers 9 or the like.
  • the seat shell 6 is pivotally guided. As a result, it can be pivoted out of a sitting position (FIG. 1) into a stacking position. In the stacking position, the free front edge 7 of the seat recess 6 has a smaller distance from the standing surface of the chair 1 than in the sitting position of the seat shell 5.
  • the seat shell 5 is preferably designed such that when the seat shell 6 is pivoted away, its center of gravity is approximately in one plane lies, which is spanned by the two Aufltäitgeoints 10 of the seat shell 6 and the direction of gravity.
  • the seat shell 5 can be formed in one or two parts.
  • the seat recess 6 and the back part 8 are connected to one another at the lateral suspension points 10 and can be pivoted together.
  • 3 finally shows a hurried number of stackable chairs 1 according to FIGS. 1 and 2 in the laterally stacked position.
  • the seat shells 6 of the chairs 1 are pivoted into the stacking position.
  • the trough-like seat shell 6 of the rear chair 1 receives the rearward protruding section of the seat shell 6 of the front chair 1.
  • the front pair of chair legs 3 of the rear chair 1 laterally overlaps the rear pair of chair legs 4 of the front chair. From Fig. 3 it can also be seen that the rear leg pairs 4 can be connected to a horizontal strut 44 to increase the stability of the support frame.
  • FIGS. 4 and 5 A variant of a stackable chair is shown in FIGS. 4 and 5 and is provided overall with the reference number 21.
  • this is a so-called cantilever chair that has a support frame 22 formed in one piece.
  • the support frame 22 is approximately bow-shaped and has a stand frame 24 with two longitudinal bars 241 and a cross bar 242 connecting them.
  • Two support arms 3 protrude from the longitudinal spars, angled at an acute angle.
  • the pivot mechanisms 10 are arranged, on which the sides of the seat shell 25 are pivotally articulated.
  • the seat shell 25 in turn has a trough-like seat trough 26 with a free front edge 27 and a back part 28. It can be made in one piece or in two parts.
  • the support arms 23 on both sides of the seat shell 25 have a light width which is greater than the width of the support frame 22 in the region of the stand frame 24.
  • the width of the stand frame 24 preferably decreases continuously from the upright projecting support arms 23 to the cross member 242. Wheels, rollers or the like can be arranged at the transition of the support arms 23 to the longitudinal bars 241 of the stand frame 24.
  • FIG. 5 shows a number of cantilever chairs 21 in a laterally stacked arrangement.
  • the trough-like seat shell 25 of the respective rear chair 21 accommodates the part of the silver shell 25 of the chair 21 which is arranged directly in front of it and which swivels back to the stacking position.
