DD244911A1 - FOLDING FITTING, PREFERABLY FOR LIEGESOFAS AND ARMCHAIRS - Google Patents

Abstract

The invention relates to a transformation fitting for couches and armchairs, which makes it possible to produce a Liegeflaeche from the seat function of the upholstery fog by high physical effort or force by the upper of two superimposed lower frames is pulled forward and thereby sitting, Lehnen- and make clamping part level with Liegeflaeche. Furthermore, it is possible to stop the transformation in the first phase, whereby the relaxation position is reached and the access to the ceiling box is released.

field of use

The invention can be applied to the construction and construction of upholstered furniture for transforming the seat function via the relaxed position to the reclining function and vice versa. The effect achieved is achieved via a Faitprinzip the frame structure.

Characteristic of the known technical solutions

The folding principle for the transformation of the seat into the lying function, realized by the articulated connection of three upholstery parts (seat, backrest and backrest clamping part) is internationally known and is realized by means of fogging in different ways.

The disadvantages of known technical solutions are:

- high fitting costs (often are complete metal frames with high weight);

A part of the solutions must be removed from the wall during transformation;

- existing solutions made of wood do not have sine required weight loss when lowering the backrest part, so that when turning a high physical effort is necessary;

- The fitting must be ver cornered by elaborate upholstery design or sleeves ;

- many transformation solutions have no storage space for blankets or even bed crates;

- No relaxation position when transforming possible.

Object of the invention

The aim of the invention is a mechanism for, by folding principle transformable. To use seating furniture so that the furniture design can be open and floor-free without covering,

when transforming from the sitting position a relaxation position is present, in which from the access in.einen bed box possible

the fitting compensates for the weight of the backrest and backrest clamping part when transforming, the fitting takes over the support function for the frame and for the leveling of the upholstered parts in a reclining function, no detachment from the wall when transforming into the reclining function is required, the transformation into the reclining function or seat function, as well as in the relaxation position, without high physical effort of the operator takes place and

in the transformation no additional handles, such as handling and / or removal or removal of upholstery elements, is necessary.

Explanation of the essence of the invention

The known technical solutions adhere to the disadvantages mentioned. Based on this, a mechanism was developed, which consists of three assemblies used in cooperation.

These assemblies are composed of the pivot point of the backrest clamping part to the frame, the scissors with two separately acting hinged joints and the stop (mounted on the frame).

The pivot point was fixed so that when pivoting by 90 °, the backrest clamping part is guided away from the wall up, 'without causing the upholstered furniture must be pulled away from the wall. The scissors consists of two unequal length levers, a tension spring and a support piece at the scissors point pivot point. This assembly causes / that when lowering the

Backrest and backrest clamping part opens the scissors and thus the tension spring is tensioned. Thus, at the moment of their maximum extension, the load of the lowering frame components with padding is absorbed. In the opposite direction, this fitting spring is a Vervyandlungs- and force expenditure help. About the support piece on Schernenspritzdredrehpunkt the load in the reclining function is transmitted to the base and a level equality of the upholstery zueinarider.gesichert. The stop, made of sheet metal, ensures by the striking of the rear wheels the relaxed position, as well as the security at the side access to the bed box

 The fitting can be used for armchairs as well as for two- and three-seat sofas.

Embodiment.

In the drawings, the embodiment of the invention is shown. It shows the

Fig. 1: the side view in the sitting position, Figure 2: the side view in the relaxed position, Figure 3: the side view in the lying position.

In the sitting position, the upper frame 1 is located above the lower frame or ceiling box 2, wherein the seat frame front piece 3 engages on the lower frame 2 and thus an independent unwanted transforming is excluded.

The movements to transform from the sitting position on the relaxation position to the bed made by moving forward of the upper frame 1 with the seat part 5 as a unit and the associated lowering of the backrest part 6 and the pivoting of the clamping part 7 on the pivot points. The upholstery parts are interconnected with known hinges 9.

In this movement ensured in the first phase, by the striking of the rear roller of the upper frame 1 on the stop plate 4, which is worked on the fore foot of the subframe 2 in floor level, the relaxed position and securing the lateral access to the ceiling box. 2

Between the backrest part 6 and clamping part 7, the Beschlagselem ent scissors with tension spring 10 is arranged, which has three functions to fulfill.

1. When lowering the upholstery parts, the scissors 10 opens and simultaneously clamps the tension spring. Thus, at the moment of the maximum extension of the spring, the load of the descending backrest part 6 and the pivoting about 90 ° above the pivot 8 clamping part 7 is compensated.

2. Represents the spring of the scissors 10 in the transformation process in the opposite direction, ie from the lying position in the sitting position is a transformation and effort required.

3. Does the scissors 10 in the lying position a functionally required height compensation, with the scissors tip fulcrum is supported in the lying position on the subframe 2.

Claims (4)

claims: 1. folding fitting, preferably for couch sofas and armchairs, characterized in that in the sitting position a forward rollable upper frame (1) on the rigid subframe or ceiling box (2) is arranged while the Sitzrahmenvorderstück (3) in the subframe (2) locked , wherein the backrest part (6) with the seat part (5) and clamping part (7) by means of hinges (9) known per se, but the clamping part (7) below the pivot point (8) with the subframe or ceiling box (2) , in itself, however, mutually rotating or. are arranged pivotally. 2. Faltbeschlag, preferably for couch sofas and chair according to item 1, characterized in that in the sitting position between the backrest part (6) and the clamping part (7) parallelogram a pair of scissors with tension spring (10) fixed in itself, but movably mounted on the three fulcrums is, which stump angle stretches in lying position and the scissors fulcrum (11) on the subframe or ceiling box (2) is seated and thereby ensures a functionally necessary height compensation of the bed. 3. Faltbeschlag, preferably for divans and armchairs, according to items 1 and 2, characterized in that when pulling the upper frame (1), the rear roller on the stop plate (4) is stopped, the relaxation position is reached while access to the ceiling box ( 2) is secured. 4. Faltbeschlag, preferably for couch sofas and armchairs according to item 1,2 and 3, characterized in that the tension spring of the scissors (10) when lowering the backrest part (6) and clamping part (7) fully absorbs the load at the moment of the maximum excerpt and When reconverting also represents a Kraftaufwandshilfe or conversion aid.
