DE3201261C2 - Spring fitting for sitting / lying furniture with several upholstered parts - Google Patents

Description

The invention relates to a spring fitting for a piece of furniture with several upholstery parts, which can optionally be used as Seating furniture or as a lounger can be used, with a bed box support frame with a forward pull-out Upper and lower pull-out frame connected, as well as a bed box frame from a back upholstery frame is partially covered and the bed frame and the lower pull-out frame are connected to each other via the spring-loaded fittings, which slide in guide rails and a longer one and have a shorter lever, the fixed hinge point of which is attached to a bed box support frame

attached angle profile piece are attached.

Such a piece of furniture is known from DE-AS 25 42 941. Around the bed frame and the lower one and upper seat cushions on the guide rails with the bed box frame open with the support feet to be able to pull forward so far that the back cushion is placed on the back cushion support frame the bed box support frame must first be manually locked to the lower pull-out frame ίο and unlocked again after the support feet of the frame have been put on. This locking and unlocking is not only cumbersome, but also material and time consuming.

The invention is based on the object of eliminating the ger annten disadvantage by locking and unlocking the frame parts solely by means of the spring force and the leverage of the spring fitting opening and closing process is carried out.

According to the invention, this object is achieved in that the shorter lever of the spring fitting is behind its point of articulation on the angle profile piece has a triangular bevel that when open Bed box frame engages in a semicircular recess of the lower pull-out frame that the bed box mounting frame a stop lock for hitting against the lower pull-out frame and that the triangular fold on the shorter lever of the spring fitting on one arranged in a bolt holder and the lower pull-out frame piercing bolt hits

The task can be solved in that the shorter lever of the spring fitting behind his The articulation point on the angled profile piece has a triangular bevel, which when the bed box frame is open A stop lock engages in a semicircular recess in the lower pull-out frame has, in front of which the fold for locking the lower pull-out frame is placed.

The two solutions of the invention are given in the The following description is explained in more detail with reference to the exemplary embodiments shown in the drawings. It shows

F i g. 1 shows a cross section of the furniture in the sitting position,

F i g. 2 an enlarged section of the spring fitting with the bed box closed,

F i g. 3 shows an enlarged section of the spring fitting with the bed box open, FIG. 4 shows a section BB according to FIG. 3, fig. 5 shows a section AA according to FIG. 3,

F i g. 6 shows a cross section of the furniture according to the second Solution in the sitting position and

F i g. 7 shows an enlarged section of the spring fitting according to FIG. 6th

A lower pull-out frame 2 lies on a bed box frame 1, which is slidably connected in guide rails 4 to a spring-loaded fitting, which has a longer lever 3a and a shorter lever 3b , and protrudes at its rear into a cavity 21 of a back support part 5.

The fixed hinge points of the levers 3a, 3b are at one fixed to the lower frame 2 extract angle profile piece 27 attached. On the lower pull-out frame 2, a bed box support frame 6 is arranged, the width of which corresponds to the lower pull-out frame 2 and is flush with it, while it has an overhang 7 at the front and is flush with the depth of the bed box frame 1 at the rear. In the

Frame 2 and 6 are upholstery springs, e.g. B. slats 8 inserted The lower pull-out frame 2 has additional shelves 13 at the front, while the bed box support frame & front in a recess of the bed frame 1 and the lower pull-out frame 2 support feet 14 with rollers The front overhang 7 of the bed box support frame 6 serves as a grip element to remove both frames 2 and 6 with the aid of the spring-loaded fitting of the bedding diagonally upwards and then to pull it forward and put it on the floor. ι ο

The short lever 36 of the spring fitting is beveled triangularly from the center of the pivot point 9 to the inside and bevelled at a right angle at its end.The protruding part of the fold 10 rests with its angle in the recess 11 and locks the stop lock 12 with its angle part of the bed frame trailer frame means 6. the locking of this frame 6 takes place with a latch 26 which is arranged in a bolt fixture 25 during the opening operation, the bending presses 10 of the lever 3b against the latch 26, whereby the latter 'is vertically raised and sits in front of the abutting block Yi. The bed box support frame 6 is thus locked, while when the frame 2 and 6 are placed on the floor, the bolt 26 falls back into its starting position and the lock of the bed box support frame 6 is released.

The bed box support frame 6 has a seat cushion 16 on which a congruent cushion 17 rests The seat cushion 16 is at its rear upper edge with the rear lower edge of the cushion 17 through a releasable hinge 18 connected. A back cushion 19 is arranged on the cushion 17 its rear surface on the closed part 20 of the back support part 5. The cavity 21 de ·. Back support part 5 prevents the bed box 1 from being blocked during the movement sequence when the bed box 1 is opened Pads 16 and 17 on their rear surfaces.

The frames 2 and 6 with their cushions 16 and 17 are used to convert from the sitting to the lying position pulled forward from the open position of the bed box and with their support feet 13,14 or the rollers 15 placed on the floor. The bed box support frame 6 with the cushions 16 and 17 is pulled horizontally forward with the help of the rollers 15 until the lock 22 of the bed box support frame 6 strikes against the inside of the lower pull-out frame 2. The upholstery 17 is folded around the hinge 18 on the lower pull-out frame 2 and the back cushion 19 is placed on the back padding frame 24

In the case of the furniture according to de: i F i g. 6 and 7, the folding process of the cushions 16 and 17 is changed because the two cushions 16, Y1 are connected with the aid of a hinge 28 located at the front in the sitting position. In addition, the stop lock 12 is attached to the pull-out frame 2. If this pull-out frame 2 is to be locked when the bed frame 1 is open, the fold 10 lies in front of the stop lock 12.
