Definitions

  • the invention relates to seating furniture according to the preamble of claim 1.
  • Such seating is known, for example, from DE-GM 77 11 928.
  • the support parts and the armrest parts are made of flexible material and flexible.
  • the flexible armrests result in considerable material problems.
  • they can be constructed from a steel spring band as the core, which is covered with elastic material, for example integral foam.
  • elastic material for example integral foam.
  • this construction tends to buckle easily when the often very large loading forces have to be absorbed.
  • One is also very restricted in the choice of materials for the casing.
  • the usual, inexpensive materials such as wood, solid plastics and the like. are eliminated due to a lack of elasticity.
  • This armrest construction is therefore also expensive.
  • the de depending on the backrest inclination formed armrests also aesthetically unsatisfactory.
  • the known seating meets the user need to ensure a permanent connection of the armrests with the seat and backrest, even if they are inclined towards each other. If this is not the case, the armrest is only connected to the seat, for example, when the backrest is inclined there is a gap to the armrest, or the armrest protrudes beyond the backrest when the backrest is in a vertical position. This results in dangerous clamping points.
  • the armrest is attached to the backrest, it projects upwards at an angle when it is tilted. A person sitting down can then get stuck with his pocket.
  • it is also a mechanical problem to introduce the considerable supporting forces of the user into the lower part of the chair via the backrest.
  • the solutions mentioned are also aesthetically extremely unsatisfactory.
  • the backdrop guide can either be in the seat or in the backrest. In most cases, however, it is advantageous to place the link guide in the seat, where it then runs approximately horizontally. This advantageously results in a constant armrest height for the user.
  • the almost horizontal seat also offers better design options than the approximately vertical backrest. In terms of strength and function, it is very advantageous to rigidly connect corresponding pivot bearings of the armrests, in particular their bearing journals.
  • the armrests are designed as rigid connection parts between the seat and the backrest.
  • a third hinge at the front at the junction of the support part and armrest part is not necessary here. This not only saves construction effort and costs, it also results in much better design options.
  • the armrests are designed exclusively for the strength requirements of the acting forces can be. This prevents buckling or bulging.
  • an elastic covering material for the armrests can be used in connection with a load-bearing core just as well as rigid and self-supporting material, such as wood, plastic, metal, etc.
  • the invention offers the advantage, particularly in times of shifting material costs, of being able to select the cheapest materials in terms of design and price regardless of certain combinations. It also avoids excessive stress on the bearings, which arise when deformation forces have to be applied to the elastic deformation of flexible armrests.
  • the cover can be achieved by assigning a base part to the support part of the armrest, which is designed in such a way that the pivot point stored in the link is covered constantly.
  • Armrests are very often not loaded vertically, but rather at a slight angle to the outside, for example when a user supports himself when standing up. For this it is a great advantage to connect the corresponding bearings of both armrests to each other by means of a rigid connection. Because this creates a bond in terms of strength, which prevents bending forces on the bearings and the resulting tilting of the armrests as well as high bearing edge loads. It it is sufficient if only a corresponding pair of rotary bearings is connected. It is also advantageous to tie the pair of bearings to the seat because the rigid connection, in particular a rod, can be laid in or even better under the seat, where it is better out of sight than on the backrest.
  • An advantageous embodiment also consists in providing round bearing bolts which are each inserted into the ends of a connecting round tube. This results in a simple, rigid and very inexpensive solution.
  • Fig.l a piece of furniture in the form of a swivel chair with seat 1, backrest 2, armrests 3 and pedestal 13 is shown.
  • the armrest 3 comprises a front, upwardly striving support part 15, and an arm support part 14 rigidly connected to it. Both parts consist of rigid material, for example of a metal bracket with a padded arm support made of plastic.
  • the armrest parts 14 are articulated on the backrest 2 with the pivot bearing 4.
  • the support parts 15 are connected to the seat 1 via the pivot bearings 5. This is movably guided in the longitudinal slot of the link guide 9.
  • the position of the seat 1 and the backrest 2 can be changed in relation to one another by means of an adjusting device 20 known per se (e.g. according to EP-A 78.200139), the seat angle, i.e. the angle between the seat and backrest, with changes.
  • FIG. 2 shows how the corresponding pivot bearings 5a, 5b of the armrests 3a, 3b are connected by a mechanically rigid connection.
  • This mechanically rigid connection is a rod 6, in this case a tube, at the ends of which bolts 7a, 7b are provided which engage in the support parts 15a, 15b of the armrests 3a, 3b.
  • the armrests 3a, 3b are articulated on the backrest 2 by means of the bolts 8a, 8b.
  • the bolts 7, 8 of the pivot bearing can advantageously be an integral part of the armrests 3.
  • the rod 6 connects the two armrests 3a and 3b to one another below the seat cushion within the seat 1 by pushing the bolts 7 into the tube 6 from the outside inwards and connecting them.
  • the connection of bolt 7 and tube 6 expediently takes place releasably, for example by a screw 19 or pins, split pins and the like.
  • the bolts 7 are guided in the longitudinal slot of the link guide 9 and can rotate in the link guide.
  • the link guide 9 can be an integral part of the seat 1, for example, is arranged as a plastic part with storage properties in the seat frame 18 (Fig.4b). If the link guide is provided in the backrest, it is arranged in the backrest frame.
  • the link guide can also be attached as a separate component on the seat 1 or on the backrest 2, if the seat and / or backrests are made of plastic shells, e.g. made of fiberglass or deformed plywood, the backdrops can advantageously be provided in the side cheeks of the shells.
  • the sliding block 10 is made of plastic and has a hole in the middle for receiving the bolt 7 and two surfaces on the outside which slide along the bearing surfaces of the link guide 9. This results in a reduced surface pressure. This is shown in Fig.4a and 4b. As can be seen, the bolt 7 is inserted into a recess 17 of the armrest 3b and is integrally connected to it, e.g. welded.
  • the link guide 9 is positively provided in the frame 18 of the seat 1.
  • the bolts 8 on the backrest 2 which are not connected to a connecting rod, are inserted into a hole on the left and right in the frame of the backrest 2 and are releasably secured there against falling out.
  • a bearing bush (not shown) into the backrest.
  • the Armrests 3 with the bolts 7, 8 attached to them are advantageously attached from the outside. They are also advantageously releasably connected to the connecting tube 6. Suitable detachable connections are, for example, dowel pins, screws, locking washers, locking rings and the like, which prevents them from falling out. Since the plug-in connection absorbs the armrest forces acting vertically, no great strength requirements are imposed on the connection. A special securing on the link guide 9 can then advantageously be omitted.
  • the armrests 3a, 3b are mutually secured by the rigid connection via the rod 6.
  • Fig. 3 shows armrest designs, which cover the backdrop by their design.
  • the front support parts 15 of the armrests 3 have base parts 16, which extend over the longitudinal slot of the link guide 9.
  • the backrest 2 is in its foremost position.
  • the distance 12 between the bearing 5 and the rear edge of the base part 16 is chosen to be at least as large as the slot in the link 9. The same distance is advantageously chosen from the front edge of the base part.
  • a ring back is also shown in broken lines in FIG. 3, with which the covering of the slot of the link guide 9 is effected particularly successfully.
  • two connecting rods 6 or only one can be used. You can connect the corresponding bearings of the backrest 2 and / or the seat 1 depending on the conditions of the seating. If only one connecting rod 6 is used, then either the link-guided bolts or the other bolts guided in bores can be connected to one another.
  • a solution is also possible in which two bolts are saved.
  • a bearing pin is firmly inserted in the backrest 2 per armrest.
  • the connecting rod 6 is extended so far that it projects right and left into the armrests 3a and 3b.
  • the armrests in turn have corresponding receiving bores into which the connecting rod 6 is then inserted and secured against falling out.
  • the connecting rods 6 can also be bent or bent.
