Definitions

  • the invention relates to a chair with a pedestal and a hinged thereto carrier, which is coupled to a seat and this carries, wherein the seat is rotatable about an axis of rotation or pivotally connected between a sitting position and a raised position with the carrier and wherein the carrier Has at least one receiving area for the aligned investment of a bayed identical chair.
  • Office chairs are known whose seat, consisting of a seat and a backrest, is rotatably mounted about a vertically arranged axis on a pedestal.
  • the pedestal can be designed as a base.
  • Such a base is usually formed of four or five arms to which pivotally mounted rollers are attached.
  • a disadvantage of such chairs is the large storage space they need for storage, since they can not be stacked.
  • an office chair with a synchronous rocking mechanism is known.
  • the rocker mechanism allows simultaneous adjustment of the seat during an adjustment of the backrest of the chair.
  • the chair is constructed of a tube frame, wherein a reference between the tubes is stretched and forms the seat or the backrest.
  • the seat is rotatable in its rear area and directed obliquely upwards linear movably mounted. At the same time the seat is rotatably mounted in its front area.
  • a second identical office chair can be pushed from behind into the first office chair. The seat of the second chair slides under the seat of the first chair and pushes it up along its linear guide. The seat thus forms reception areas, where a second chair can be joined.
  • the arms of a base formed as a base of the chair are rearwardly higher at a node fastened than the forwardly directed arms, so that the front arms of the rear chair can be pushed under the rear arms of the front chair. It can be strung together as many office chairs.
  • the disadvantage of the seat of the office chair must be made narrower than the backrest, so that the tubular construction of the seat between which the backrest can be inserted. This is at the expense of the seating comfort.
  • receiving areas, on which a second chair can be lined up are formed on the seat surface. This results in an increased wear of the seats when they rub against each other when inserting a chair.
  • a stackable and telescopically chair is known.
  • Two mutually spaced first frame parts form rear, mounted on rollers chair legs, which pass upwards in armrests.
  • second frame parts arranged in a crossed manner relative to the first frame parts, which form the front, provided with rollers chair legs and carry the backrest in the upper area.
  • the seat of the chair is rotatably mounted in the opposite crossing points of the first and second frame parts and can be pivoted between a sitting position and an erect position. In the erected position identical chairs can be strung together, with the backrest of the front chair is based on the base of the seat of the rear chair.
  • the chairs can be stacked on top of each other with the seats folded, with the rollers of the respective upper chair being guided along and mounted on the frame parts of the lower chair.
  • the construction of the chair does not allow the use of a pedestal, so that it can not be realized with chairs with rotatably mounted seats.
  • the object of the invention is achieved in that the seat is swung out in the raised position of the receiving area of the carrier and this frun.
  • the one-level seating surfaces prevent the chairs from being placed close together.
  • the seat surface releases the receiving area, which is advantageously arranged on the support of the chair.
  • it is moved so far away from the receiving area by the pivoting movement, that a provided for investment section of a chair to be adorned on the seat over, for example, under the established seat through, can be pushed to the receiving area.
  • chairs can be pushed together and lined up to save space, without the seats abutting and wear out.
  • the carrier has an outwardly open inner receiving area and / or that the carrier has an outer receiving area and that the seat in the erected position the inner receiving area and / or the outer receiving area grisfensiv.
  • the inner and outer receiving areas can be designed so that the outer receiving area of one chair engages in the inner receiving area of a rowed chair.
  • the chairs are so with their straps to each other, which were previously released by the erection of the seats.
  • defined contact surfaces for example made of plastic, can be applied to the inner and / or outer receiving region of the wearer of the chair. These contact surfaces can then form the stop between juxtaposed chairs.
  • the seats or the backs of juxtaposed chairs and their covers do not come into contact with each other.
  • the carrier partially or completely made of plastic. As a result, the wear can be minimized.
  • An essential idea of the invention is that juxtaposed chairs only touch the carriers. Thus, the contact takes place only in a non-visible area of the chairs. Visible areas do not touch and are therefore not exposed to increased wear.
  • the mutual alignment of the chairs can be done by the contact of the wearer.
  • Suitable receiving areas can be obtained in that the carrier has two legs, that the legs are connected at one end and that the mutually facing portions of the legs at least a portion of the inner receiving portion and the opposite portions of the legs form at least a portion of the outer receiving portion ,
  • a support constructed in this way can be produced inexpensively. It allows for a secure support and support of the seat in their sitting position and on the other hand, the formation of suitable recording areas to build identical chairs next to each other.
  • the legs are at least partially U-shaped or V-shaped to each other, the chairs are aligned when juxtaposed against each other and centered.
  • the legs can be executed straight, but also bent.
  • the seat and a backrest of the chair are integrally connected to each other and / or that the seat and the backrest are made separately and that the backrest is attached directly or indirectly to the carrier.
  • a one-piece seat and back can be inexpensively, for example, as a plastic molding produced. It is also possible, the seat and the backrest made of plywood, preferably made of molded plywood (mold) to produce. In such one-piece seats can advantageously be adjusted together with the seat backrest to get a favorable position for juxtaposing the chairs for both.
  • a separately executed seat can be leaned in its raised position to the backrest and held by this in the erected position, without the need for additional components are required.
  • the seat can be pivoted out of the receiving area of the carrier in that the axis of rotation is formed by a hinge connection between the seat surface and the carrier and that the hinge connection in a front region of the seat, in particular along a front edge of the seat, or in a rear area the seat surface, in particular along a rear edge of the seat, is arranged.
  • the arrangement of the axis of rotation between the carrier and the seat and along an edge of the seat is raised in its raised position completely over the carrier. As a result, the one or more receiving areas of the arranged below the established seat carrier are free.
  • the chair two pivoting armrests are assigned and that the armrests pivot when adjusting the seat between the sitting position and the erected position.
  • the armrests can thus be placed in a position that allows two chairs to be placed close together.
  • the seat is held independently in its raised position.
  • the unloaded seat can be automatically held in its upright position, characterized in that between the seat and the support at least one actuator, in particular a gas spring, is arranged, which acts with a directed from the sitting position in the established position force on the seat. At the same time, the actuator acts as a cushion when the seat is moved back to its sitting position.
  • at least one actuator in particular a gas spring
  • a stop to be arranged on the carrier on which the seating surface rests directly or indirectly in the sitting position such that the stopper forms part of the outer receiving area and / or part of the inner receiving area. and that the stopper is adapted to cooperate with a stop receiving a geflindhten chair.
  • the stopper performs two functions. On the one hand, it serves as a safe and resilient support for the seat in its seating position. On the other hand, he intervenes in the receiving area of an adjoining chair and thus sets the correct position of the chairs to each other. This can prevent that chair parts accidentally abut each other and the chairs are damaged.
  • a stop buffer is arranged on the seat surface, that the stop buffer rests in the seat position of the seat on the stop and / or that the stop buffer in the erected position of the seat in an Anreih direction to an adorned identical chair is aligned. Together with the stop, the stop buffer forms a secure and resilient support for the seat in its sitting position.
  • the stop buffer may be made of an elastic material, in particular made of rubber.
  • the stop buffer acts shock-absorbing with changing loads on the seat.
  • the bumper shows in a direction from which another chair can be strung. If a chair is lined up, it can, for example, with its seat or its backrest, abut against the stop buffer of the adjacent chair.
  • the footrests In order to be able to line up chairs, the footrests must not obstruct the way. This can be achieved by virtue of the fact that the base frame is rotatably connected to the carrier and that a locking device is effective between the base frame and the carrier such that at least in the erected position of the seating surface the base frame and the carrier are aligned in a predetermined rotational position. In the predetermined rotational position of the carrier with the seat and the pedestal are aligned against each other so that a chair can be applied to the receiving area of a second chair and at the same time the pedestals can be pushed into each other. It can be provided as a chair with a rotatable about a vertical axis seat, which can be arranged to save space to other identical chairs.
  • the pedestal and the seat of the chair can thereby be automatically aligned with each other, that the pedestal is connected to the carrier rotatable about a second axis of rotation and biased against gravity and that a coupled to the carrier locking member engages in relief of the seat in a centering of the pedestal , Once the seat is relieved
  • the carrier is aligned with the seat relative to the contemplatun in such a way that the chair can be queued to a chair of the same design.
  • the pedestal is formed by a base, that arms of the pedestal are laterally offset to each one of a node of the pedestal outgoing radial line attached to the node and that the feet in a direction of rotation to the node to the respective radial line are arranged.
  • Chairs with such executed monrizen can be pushed together with a suitable alignment of the contemplatnche and thus strung together.
  • the locking can be done as previously described.
  • the foot crosses are aligned in a locked position so that one arm of the base, relative to the seat of the chair, facing forward, one to the rear and two more to each opposite sides of the chair show.
  • the arms at the node By arranging the arms at the node, the rear arm of a front chair and the front arm of a rear row chair are offset laterally.
  • the chairs can be strung together, with the mutually facing arms of the frames are pushed past each other.
  • the arms, starting from the node are aligned obliquely downwards.
  • the front and / or rear arm of a chair can thus be pushed under a lateral arm of an adjoining chair.
  • a possible variant of the invention is such that the carrier protrudes beyond the second axis of rotation and that the inner and the outer receiving area are arranged at least in sections on the projecting carrier area.

  • chairs 10 can be strung together in the manner described.
  • the outer receiving area 29 of the carrier 20 of the rear chair 10 is inserted into the inner receiving area 28 of the carrier 20 of the front chair 10.
  • the stop 25 of the carrier 20 of the rear chair 10 is inserted into the stop receptacle 27 of the carrier 20 of the front chair 10. This results in a relative positioning of juxtaposed chairs 10 to each other.
  • lateral guidance of the chairs 10 takes place through lateral sections of the inner and outer contact areas 28.1, 29.1, on which the carriers 20 rest against one another.
  • a straight row of aligned chairs 10 is obtained.
  • the seats 11 are held independently in the raised position, so that no forces transmitted to adjacent chairs 10 and thereby increased wear is caused.

Abstract

L'invention concerne une chaise (10) qui comporte un piètement (40) et un support (20) monté de manière articulée sur celui-ci et relié à une assise (11) et supportant cette dernière, l'assise (11) étant reliée au support (20) de manière à pouvoir pivoter ou basculer autour d'un axe de rotation (30), entre une position utile de siège et une position relevée, et le support (20) présentant au moins une zone d'emboîtement (28,29) permettant le positionnement en alignement d'une autre chaise (10) de conformation similaire. Lorsque le siège est en position relevée, l'assise (11) est pivotée à l'opposé de la zone d'emboîtement (28,29) du support (20) et libère celle-ci. On obtient ainsi une chaise (10) conçue pour pouvoir être entreposée avec un faible encombrement avec des chaises (10) de conformation similaire juxtaposées les unes aux autres.
