Definitions
- the present invention relates to seating furniture with a seat and backrest according to the preamble of independent patent claim 1.
- Seating furniture in which the area of an elastic pivoting of the backrest relative to the seat is adjustable and, if necessary, can also be pivoted elastically from a selectable basic position.
- the seat and backrest without a backrest support are only connected to one another at their edge parts.
- the connection is resilient so that the backrest can be pivoted relative to a side frame support connected to the seat.
- the backrest is provided with an upper cushion part, which is also pivoted relative to the backrest. Both joints have spring elements, so that a force has to be applied to pivot the parts against one another.
- the spring element is a helical spring which, supported on one part, pulls a pin with an arched head into a pan.
- the two parts can be pivoted about an axis of rotation located outside of this joint arrangement, so that a restoring force arises when pivoting out of a normal position.
- a second embodiment are in the divided Frame supports two resilient plastic parts are used, which exert a restoring force on this press plate in a limited swivel range of a rotatably mounted press plate when the backrest is swung out of the normal position.
- the double joint allows the back and neck to be supported while the body is in a relaxed position.
- there is a frame for holding the seat and the backrest which consists of a large number of individual parts, as a result of which such seating furniture can only be produced at a high price.
- CH-A 611 502. Between the seat and backrest, which are each shown as self-supporting elements, a connecting element is arranged, which acts as a spring due to the shape.
- the connecting element, the seat and the backrest are integrally connected to one another. Wood, metal, plastic, alone or in combination, are suitable as materials.
- Such seating is of course very cheap to manufacture because it can be made by stamping and, in the case of sheet metal, by pressing.
- the fact that it is possible to manufacture the seat, backrest and connecting element from the same material means that means which are not mentioned must be present so that on the one hand the connecting element is flexible and on the other hand the seat and backrest are rigid.
- seat 1 consists of seat 1 and backrest 2, which are designed as shells of the same shape, and of two connecting elements 3, 4 for the elastically yielding connection of seat 1 and backrest 2.
- chair legs 5-8 attached on the seat 1 .
- the two identical shells for seat 1 and backrest 2 have two support ribs 10, 11 on the side and a plate 12 located between these support ribs 10, 11.
- the plate 12 is recessed in the middle to fit the seat, and the section 13 projecting over the supporting ribs 10, 11 is convexly curved, so that the edge is arranged under the seat surface behind the seat and behind the support surface at the backrest.
- the chair legs 5-8 are inserted into the supporting ribs 10, 11 and attached to them, as will be described later.
- the connecting elements 3, 4 are also inserted into the supporting ribs 10, 11.
- FIG. 2 The formation of the connecting elements 3, 4 and their attachment in the support ribs is shown in Fig. 2 on an enlarged scale.
- This type of fastening takes into account the fact that the shells are made of polypropylene, which has only a limited mechanical strength, in the case of screw connections, in which a wall section made of polypropylene between a screw head and a plate-like part made of another rigid material, such as, for example the chair legs, pinched, would break out if the wall thickness and therefore additional material are not provided.
- the connecting elements 3, 4 mainly consist of a band-shaped spring element 30 which is angled so that the two legs 31, 32 of approximately the same length form an obtuse angle of at least approximately 100 °.
- the ends 33, 34 of these legs 31, 32 are inserted in axial slots 35, 36 of cylindrical pins 37, 38 and rigidly held by means of screws 39, 40 which are screwed through the legs into the opposite side of the slot 35, 36.
- the portion 41 between the two pins 37, 38 is integrally foamed polyurethane to protect the user and the spring element 30 and can be characterized in an aesthetically appealing manner by circumferential beads as a spring element.
- the channels 12, 13 of the support ribs 10, 11 are formed on the end parts as cylinders 14, 15 which are closed on one side.
- a bore 18, 19 is located in the end wall 16, 17 of the cylinders 14, 15.
- the inside diameter of the cylinders 14, 15 and the diameter of the pins 37, 38 are dimensioned to fit a fit, so that the pins 37, 38 can be pushed into the cylinders 14, 15.
- the pins 37, 38 are fastened in the cylinders 14, 15 by means of 0-rings 40, 41 made of elastic material, which according to FIG. 2 are placed around a cylindrical guide 42, 43. With a screw 44, 45 screwed axially into the pin 37, 38, the pin 37, 38 is pulled against the end wall 16, 17, as a result of which the O-ring 40, 41 is pressed together and thus pressed against the cylinder wall.
- This bracket is sufficient to rigidly connect the two chair parts, the seat 1 and the backrest 2.
- wall thicknesses of 4 mm are sufficient for the cylinders to be able to absorb the forces when using polypropylene for the shells of the seat and backrest.
- spring elements 30 it was assumed that those with a force of up to 15 kg at a point 30 cm
- Spring elements loaded over the seat are rigid and resilient in a range between 20 and 25 kg and have a strength under permanent load before 35 kg.
- FIG 3 and 4 show two variants for the type of fastening of the pins 37, 38 described above in the cylinders 14, 15. Only the fastening to the seat 1 is shown, the fastening to the backrest 2 is identical, as is also shown in FIG 2 emerges.
- a disk ⁇ 49 made of elastic material, which is pierced centrally.
- the outer surface of this washer 49 is covered by a washer 48 and a screw 47 serves to compress the elastic washer 49, which thus performs the function of the 0-rings 40, 41.
- the screw head of this screw 47 is accessible through an opening 19 closed by means of a plug 46 in the partition 17.
- the arrangement according to FIG. 4 differs from the arrangement described above only in that a ring 50 with a square cross section was used instead of the disk 49 and also in that the pin 38, similar to that in FIG. 3, with a cylindrical guide which at the same time the screw-in depth of the screw 47 is limited.
- FIG. 5 to 7 show a first application of the described seat back arrangement in a chair and in an armchair with armrests.
- the problem of the strength of polypropylene described above also applies here and neither chair legs nor armrests can be screwed onto the shells in the usual way by means of screw connections.
- 7 shows the channel 13 in the rib 11 of the shell 12 clearly and on an enlarged scale
- FIG. 6 shows the rib 11 and the shell 12 in a side view.
- the two front chair legs 60, 61 engage in the channel 13 with an angled support part 62.
- this channel 13 there are, for example, two eyes 63, 64, of which the rear eye 64 is clearly drawn out in FIG. 7.
- the rear chair legs 67, 68 are connected to one another by means of a cross member 69.
- This cross member 69 is Rated Most 60, 61 angesch K on the one hand to this rear chair legs 67, 68 and on the other hand to the support portions 62 of the front chair legs.
- the armrests 70 are inserted into the rear chair legs 67, 68 with a plug-in part 71 and fixed by means of a screw 72. Without these armrests 70, the opening in the rear legs of the chair can be closed by a plastic plug.
- the rear chair legs 67, 68 are, as shown in FIG. 5, shifted outwards. The purpose of this is that the chairs or armchairs can be stacked on top of one another, as can be easily understood by any person skilled in the art.
- FIG. 8-10 Another application is shown in Figs. 8-10 in an office chair.
- Screws 84 are provided on a rigid base frame 83 in the usual way for fastening the column 80 with the star-shaped beams 81 and with the adjusting device 82.
- This base frame 83 as shown in FIG. 10, is designed as a support structure suspended on both sides, in which band-shaped supports 85 are fastened to holding rails 86.
- the holding rails 86 engage in the lateral ribs 10, 11 of the shell 12 and are held by clamping means, such as a base 87 on an eye 88, which is pressed together by a screw 89.
- the dimensions of the holding rails 86 are selected such that a distance to the channel wall is formed outside the same.
- a covering hood 90 can be pushed into this space of 3-4 mm in order to protect the adjusting device 82 from dirt.
- Armrests 91 can be designed with a self-supporting arm 92, and they can be screwed to the holding rails 86 from the outside by means of two screws 93, 94.
