TRANSFORMABLE FRAME

The solution relates to meeting the vital needs of a person, in particular to furniture, mainly to sofa beds, which are increased in size due to the elements located in them, primarily to folding bed frames.

Transformable furniture has been known since the beginning of the last century, and since the 1950s, unified elements have been widely used in the United States and Western Europe (see, for example, the books of Boger L. A. The complet te quide to furniture styles, L. , 1961, NY, 1969). In the USSR in the second half of the 50s, the design of transformable furniture began, in particular, there are known (see, for example, the magazine catalog “I choose, N ° 128, 2002) sofa beds containing a body with a back, front and rear walls and base, as well as the transformation mechanism. The mechanism comprises folding sections. This design is convenient, although for its folding into the position "bed you need to carry out four operations, that is, it can be folded out in three steps. A large number of elements, as well as articulated joints, adversely affect the rigidity of the structure. However, this design was the result of numerous improvements to the sofa beds below.

Known chairs, sofas and beds containing sections having the ability to move and mutually displace, soft elements and rollers (see, for example, US 2125940, 2568366, 3187351, 3877087, 4292697, 4620335, 4625346 and 4672696; AT 11679/66, 3869 / 67, 5336/73, 156/76, 157/76, 4627/78, 1435/79, 1674/84, 2266/89, 2640/89, 585/91, 1247/94 2211/96, 169097 and 100498; IT 28652-61, 22179U, M191U318, M1950680 and M1980565; DE 2402018, 8005674U, 19604898, 19605309 and 19803059; CH 531862 and 624286; UK 2070423, 2091092 and 2106777; CA 354842; SU

The design of this furniture is very diverse, which is caused by various interests of the consumer, while the mechanism that ensures its transformation plays a significant role in similar objects. Such mechanisms are known from security documents US 2803018, 2827640, 3906557 and 4928331; DE 4437579, 4443382 and 19747692; RU 2721, 4201, 2130751, 8883, 11027, 12645, 18227 and 18619; FR 2768909; WO 93/20732. Most often, a back rotation is provided. Rational in this case is the implementation of curly grooves on the sidewalls as it is done, in particular, in furniture according to SN 674922; AT 2266/89 and 1247/94; DE 19642460 and 19918107, as well as in convertible sofa beds according to US 4737996. Nevertheless, high consumer properties of furniture can be ensured by the rational execution of both the furniture elements themselves and their optimal interaction. However, in each of the documents cited there is no such implementation.

Mutual placement of furniture sections and communication of one section, at least with the body, is essential. The three-link mechanism for connecting the head of the chair-bed according to US 2007988 with the body is quite complicated. Two levers are provided for connecting the head of the chair-bed according to US 2287596 and RU 2146488 with the body. The single-link connection between the head of the head and the body of the chair-bed according to US 2621337 required a complex connection of the head to other sections of the bed. A closed three linker is used in a chair-bed according to US 4447921.

Transformable furniture with extension sections is effective (see, for example, US 2568366, 3877087 and 4292697, IT 27337A / 76, CH 632401 and 661855, EP 631749, RU 2110941, 2110942 and 2132149).

Known transformable frame containing a housing with which are connected having the ability to move and mutual displacement of the part (see, for example, WO 99/22625).

This furniture provides for mutual fixation of movable parts, while the middle part is installed with the possibility of pushing and pulling on

supports between the head and foot parts, the last of which is installed with the ability to move to the top of the middle and head parts. The multilevel arrangement of the main parts, as well as their ineffective fixation in the unfolded state, necessitate the use of a conglomerate of soft elements, which unsatisfactorily affects the consumer properties of furniture. The reliability of the locking rollers associated with the sections is low, which drastically reduces, like the presence of a lifting and locking hook, the ease of use in any of the very possible distortions. Equally, the implementation of the stop limiter reduces the usability, which is not always convenient for the consumer. The described complication of the design leads to additional operations when using furniture, although the effect of a different level arrangement of parts is determined by the essentially comparatively unsuccessful kinematics of the mechanism, in particular, their mutual arrangement of the axes of the articulated joints.

The task is to simplify the design and increase the reliability of the transformed frame while reducing the cost of its manufacture and operation.

Improving the reliability of the transformed frame while simplifying its design, as well as reducing costs in the manufacture and operation, is ensured by the rational connection of its elements and their interaction.

For this, in a transformable frame containing a housing, to which are connected movable and mutually displaceable parts, the housing is connected to the head through a three-link mechanism.

The communication of the housing with the head through a three-link mechanism in a transformable frame containing the housing, to which the moving and mutually displaceable parts are connected, will increase its reliability while simplifying the design, reducing costs in manufacturing and operation, since its elements that are easy to manufacture are rationally connected, and the kinematics of their interaction provides any of its states without additional efforts in a regular position, which is strictly fixed.

The implementation of the head with the ability to move satisfies the consumer in any of the furniture provisions used by him.

Placing the headboard in the level and below the seat section allows you to rationally use the backrest, which transfers forces from its outer surface to the body, which is essential for the functioning of both the headboard and back.

The middle link of the mechanism is associated with the headboard, and this allows you to rationally transfer efforts to it in any position.

The supporting link of the mechanism has the ability to be placed essentially parallel to the seat sections and for the legs, which is essential for efforts both in the transformation of furniture and in its untransformed state.

The links of the mechanism are made mainly from the profile, the surfaces of which are offset.

Depicted on:

figure 1 - frame;

FIG. 2-5 - frame during transformation;

FIG. 6 - sofa bed;

FIG. 7 - sofa bed when unfolded.

The frame contains associated with the housing 1 (figure 1) and between each other the headboard 2, seat 3 and foot 4. These parts are connected to the lining 5 of the housing 1 and have the ability to move and mutual displacement.

The frame is equipped with a three-link mechanism 6 for connecting the housing 1 with parts 2,3 and 4, that is, the connection of the housing 1 with the head 2 is carried out through the mechanism 6.

The supply of a three-link mechanism 6 for connecting the housing 1 with parts 2,3 and 4 of the frame containing the housing 1, in which parts 2-4 having the ability to move and mutually displace are placed, will increase its reliability of the sofa bed while simplifying the design, reducing manufacturing costs and operation, since elements that are simple to manufacture are rationally connected, and the kinematics of their interaction provides any of its states without additional efforts in the normal position, which is strictly fixed.

The implementation of the head 2 with the ability to move satisfies the consumer in any of the furniture provisions used by him (Fig. 2-5).

The headboard 2 is placed at the level (Fig. 2) and below (Fig. 3) of the seat 3, which makes it possible to rationally use the backrest 7 (Fig. 6), which transfers forces from its outer surface to the housing 1, which is essential for functioning as the headboard 2, and backrests 7.

The middle link 8 (Fig. 3) of the mechanism 6 is connected with the headboard 2, and this allows you to rationally transfer forces to it at any position (Fig. 2-5).

The supporting link 9 of the mechanism 6 has the ability to be placed essentially parallel to the seat sections and for legs 3 and 4, which is essential for efforts both in transforming furniture and in its untransformed state.

The links of the mechanism are made mainly from the profile, the surfaces of which are offset.

The proposed set of features used in the sofa bed (Fig.6,7).

The sofa bed functions like this.

When folding, the sofa beds act on section 4 and push it up to placement under section 3 (Fig. 3). Both sections 3.4 push in the direction of the backrest 7. With the further movement of sections 3 and 4, the head 2 is rotated relative to the horizontally located link 9.
