Definitions

  • the invention relates to a piece of seating furniture with a self-supporting seat plate attached to its legs, which is provided on its underside with slits tapering to the legs at the attachment points, which slots in the legs face in the longitudinal direction of the legs, which are aligned with the slots in the seat plate , with corner parts for the stable connection of the seat plate and legs being glued into each of the opposing slots.
  • the essential feature of this seating furniture is to design the connection of the seat and legs by triangularly shaped corner parts, which are glued with their mutually perpendicular sides into aligned slots in the seat plate and leg.
  • an arrangement of at least two corner parts is deliberately provided at each connection point. The corner parts run towards each other in the respective leg and extend at an angle enclosed by them into the correspondingly shaped slots in the seat plate.
  • the invention has for its object to provide a piece of furniture in which the construction of the attachment point between the legs and the self-supporting seat plate is simplified and improved.
  • the seating furniture should also be easily stackable.
  • the seat plate is provided at each fastening point with a single slot protruding approximately diagonally into the seat plate from the fastening point, which in its transverse direction extends essentially over the thickness of the seat plate, and in that at each fastening point the two slots a single mounting bracket in the manner of flat steel is inserted upright such that each mounting bracket fills in the slot in the seat plate and leg in the longitudinal direction of its respective leg approximately in the order of magnitude of 2 to 3 times the seat plate thickness and laterally completely so that the legs of the support bracket on the underside of the seat plate and on the inside of the leg in question.
  • the support bracket correspondingly let into the slots avoids any protrusion of its legs from the surfaces of the connected parts, so that the stackability of the seating furniture in question is in no way impaired by the support bracket.
  • the seat plates can lie one on top of the other, thereby avoiding damage.
  • the stack height is limited to the thickness of the respective seat plate.
  • the resulting large-scale support from seat plate to seat plate during stacking also offers the advantage that any padding that may be attached to the seat plate cannot be pressed in at individual points.
  • the enlargement of the adhesive surface due to only one slot in the part in question allows a corresponding reduction in its cross-section, that is to say on the one hand the seat plate and on the other hand the leg.
  • B. is a plywood board with a thickness of 25 mm.
  • the slots are expediently introduced into the seat plate in such a way that they completely penetrate the seat plate.
  • the slots can be made into the seat plate from the outside using a saw.
  • the slot of the seat plate material leaves a base which is expediently placed on the side of the seat surface, so that the optically appearing seat surface is not disturbed by the slot.
  • the slot maintains sufficient expansion in its transverse direction so that the support bracket can develop the stability it exerts on the seat plate essentially fully.
  • it is of course also possible to provide the base left standing next to the slot on the underside of the seat plate.
  • the support bracket can be provided with a profile running transversely to its longitudinal direction, for which of course a corresponding profile must be provided in the slot in question.
  • a profiling can simplify the manufacturing process, since it ensures a secure fit of the support bracket with respect to the seat plate or leg for the process of setting the bond. This also results in an increase in the adhesive area.
  • the support bracket can also be advantageously formed by injecting it into the slots after the chair leg and seat plate have been joined.
  • the slots aligned with one another form a shape for the plastic to be injected, which then hardens in it and thus establishes the firm connection.
  • the seating furniture shown in FIG. 1 represents a wooden chair with four vertical chair legs 2, 3, 4 and 5, of which the seat plate 6 is carried.
  • the chair legs 4 and 5 protrude upward beyond the seat plate 6 and are connected to one another above the seat plate 6 by the backrest 7.
  • Four slots 8 are provided in the seat plate 6, which protrude approximately in the diagonal direction into the seat plate 6.
  • support bracket 9 see FIG. 2 are inserted, via the connection between the seat plate 6 and the chair legs 2 to 5 for the purpose of attachment.
  • the support bracket 9 shown in FIG. 2 is inserted into a slot 10 in chair leg 3, which is described in more detail with reference to FIG. 2.
  • Such a slot 10 is also present in the other chair legs 2, 4 and 5.
  • FIG. 2 shows the connection of the chair legs 2 to 5 and the seat plate 6 according to FIG. 1 in an enlarged view.
  • the chair leg 3 and the seat plate 6 are shown at a distance from one another in order to facilitate understanding in connection with the support bracket 9 drawn between them.
  • the chair leg 3 is provided with the slot 10 which is aligned with the slot 8 in the seat plate 6 when the chair leg 3 and seat plate 6 are connected to one another by means of the support bracket 9.
  • the leg 12 of the support bracket 9 is inserted into the slot 10 of the chair leg 3, the leg 12 being completely absorbed by the slot 10.
  • the slot 10 has a corresponding depth for this.
  • the seat plate 6 is pushed onto the leg 11 of the support bracket 9, the leg 11 being completely received by the slot 8.
  • the slots 8 and 10 have such a width that the legs 11 and 12 completely fill the slots 8 and 10.
  • the firm connection between the support bracket 9 and the chair leg 3 and the seat plate 6 is done by gluing between the legs 11 and 12 and the slots 8 and 10.
  • the adhesive in question is expediently introduced beforehand into the slots 8 and 10, from which he then when the Legs 11 and 12 is pressed out, but a sufficiently thick adhesive film remains between the legs 11 and 12 and the walls of the slots 8 and 10, so that there is a stable connection, which is so firm when choosing a suitable adhesive that when overloaded rather the material of the seat plate 6 and the chair leg 3, here wood, breaks before the bond loosens.
  • the slot 8 penetrates the seat plate 6 completely.
  • the seat plate 6 and the support bracket 9 a position in the slot 8 results according to a corresponding dimensioning of the leg 11, according to which the leg 11 closes both with the seat surface and with the underside of the seat plate 6.
  • the support bracket 9 In order to achieve a sufficient strength of the support bracket 9, it is expediently made of flat steel or a corresponding solid aluminum alloy. It is also possible to use a correspondingly hard plastic for this.
  • FIGS. 1 and 2 The embodiment shown in FIGS. 1 and 2 is, as mentioned, a wooden chair 1, the seat plate 6 of which consists of a plywood plate with a thickness of approximately 25 mm.
  • the seat plate 6 is due to its strength easily able to absorb the forces transmitted from the support bracket 9, because the Leg 11 of the support bracket 9 protrude into the seat plate 6 with a length such that there is a sufficient distribution of the transmitted forces along the leg 11.
  • the length of the legs 11 corresponds to twice the thickness of the seat plate 6.
  • FIG. 3 shows a support bracket 24 which has a thickening 26 at the end of its leg 25, which forms a profiling which extends transversely to the leg 25.
  • the support bracket 24 is inserted into the seat plate in the direction of the arrow 28 shown. To enable this insertion, the slot in the seat plate is provided with an extension at its end.
  • the thickening 26 gives the support bracket 24 inserted into the seat plate a certain support in order to give the necessary rest for the hardening of an adhesive film surrounding the leg 25. This also increases the adhesive area.
  • the profile 33 running in the longitudinal direction is provided on the leg 32 of the support bracket 31, and the profile 35 is also provided on the leg 34.
  • the profiles 33 and 35 are again thickened portions.
  • the profile 33 is received by a corresponding recess 36 in the slot 37 of the relevant seat plate 38.
  • the profiling 33 ensures that after inserting the leg 32 into the slot 37, the leg 32 initially receives a secure hold.
  • FIG. 5 shows the seat plate 39, into which the slot 40 is let in, which here leaves the base 42 in relation to the seat surface 41.
  • the slot 40 therefore only extends to the surface of the seat plate 39 opposite the seat surface 41.
  • This introduction of the slot 40 has the result that an angle of support inserted into the slot 40 is not visible on the seat surface 41.
  • the base 42 has only such a strength that a support angle inserted into the slot 40 extends essentially over the full strength of the seat plate 39, so that practically the full strength of the seat plate 39 is used for the introduction of forces into the seat plate 39.
  • the support angles protruding into the respective seat plate are glued to the seat plate, the respective support angles being of such a strength that they completely fill the slot in question, but there is still enough space for gluing an adhesive film can form, which then ensures the firm connection between the support bracket and seat plate.
