Description

The utility model relates to the furniture industry, in particular to furniture for sitting and lying, which is transformed from a sitting position to a lying position by extending elements, and can be used in the manufacture of transformable upholstered furniture products, namely sofa beds, and is intended to simplify the process of transformation, changing the size of the sleeping place of the sofa bed. The sleeping place transformation mechanism (MTSM-06vf (Springboard)) is used in upholstered furniture in sofa beds to create a sleeping place in a sofa with supports from 120 mm to 150 mm high.

Designs of transformable furniture for sitting and lying are known, the sleeping place of which is formed from several sections, and at least one of them is movable relative to the other and is transformed according to the “dolphin” principle: it rolls out from under the seat and rises to its level https:/ /www.favorittextil.ru/katalog/dlya-myagkoj-mebeli/mekhanizmy-transformatsii/stalmot/mekhanizmy-transformatsii-spalnogo-mesta/mekhanizm-transformatsii-ws189-5-detail, https://orlovskaya-obl.tiu.ru /p169301383-mechanism-transformatsii-dlya.html.

The closest analogue of the claimed utility model, taken as a prototype, is a mechanism for transforming a corner sofa-bed, including a sofa base, a retractable base, connected by means of guides on the base of the sofa and roll-out wheels interacting with these guides, mounted on a retractable base, a side base, made of of metal pipes and equipped with supporting parts, a linen box, characterized in that tubular structural elements of the sidewalls of the sofa base are used as guides for the drawer base, a plate is welded between the tubular guides, which limits the maximum movement of the drawer base during transformation from the “sofa” position to the “bed” position ”, to which stops are welded to counteract the movement of the base of the retractable to the left or right during transformation, excluding possible jamming in the “withdrawable roller-guide” pair, protective plastic pads are installed on the stops, linen th box interacts with the side base installed on it using lifting mechanisms that provide unhindered access to its contents, and is attached to the base of the sofa using wedge hooks, with the possibility of mounting both on the left and on the right (RU 195984 U1, 02/12/2020) .

The main disadvantage of this technical solution is that in the folded state the wheels of the "dolphin" transformation mechanism stand on the floor, which spoils the design of the model.

The technical problem of the utility model is to eliminate the above disadvantage and expand the arsenal of tools.

The technical result of the claimed utility model is to ensure the transformation of the sleeper of the sofa-bed with high supports with the possibility of folding the wheels and eliminating their contact with the floor in the assembled state of the sofa.

The technical result of the utility model is achieved by the fact that the device for transforming the sliding part-sleeper of the sofa bed, containing the transformation mechanism "dolphin" and the first and second guides located on the side of the seat of the sofa bed,

- at the same time, the "dolphin" transformation mechanism contains the upper and lower sections, which are transformed with the help of rods into the folded and unfolded states,

- the upper section is made with the possibility of fixing on it the retractable part-sleeper of the sofa bed, which is in the folded state under the seat of the sofa bed, and in the unfolded state - at the level of the seat height;

- the lower section is made with the possibility of interaction with the first and second guides, as well as with the floor, by means of a wheel system, including the first and second movable wheels, transport and support wheels;

different in that

- the first movable wheel is located in the front part of the "dolphin" transformation mechanism and is configured to move along the first guide;

- the second movable wheel is located in the rear part of the "dolphin" transformation mechanism and is configured to move along the second guide;

- transport and support wheels are located in the front part of the "dolphin" transformation mechanism and are made with the possibility of interacting with the floor;

- the first guide is located under the second guide and contains an inclined section with the possibility of lifting the front part of the "dolphin" transformation mechanism together with the transport and support wheels located in this part and their corresponding lifting from the floor in the process of folding when moving along the specified section of the first movable wheel and with the possibility of lowering the front part of the transformation mechanism "dolphin" in the process of unfolding when moving along the specified section of the first movable wheel;

- the second guide contains a straight section and an inclined section associated with it with the possibility of raising the rear part of the "dolphin" transformation mechanism in the process of folding when moving along the indicated sections of the second movable wheel and with the possibility of lowering the rear part of the "dolphin" transformation mechanism in the process of unfolding when moving along the specified sections of the second movable wheel.

The proposed utility model is illustrated by drawings.

In FIG. 1 shows the sofa bed in the folded state.

In FIG. 2 shows the sofa bed at the initial moment of unfolding, when the transport wheel 7 leaves the first guide 5 and touches the floor.

In FIG. 3 shows the moment when the straight section of the second guide 6 ends and the rear wheel 11 starts downhill.

In FIG. 4 shows the moment when the inclined section of the second guide 6 ends and the rear wheel 11 stops and limits the movement of the mechanism forward.

In FIG. 5 shows the moment of the beginning of the transformation of the sleeping bag, when the wheels 7 and 8 are simultaneously on the floor and subsequently the entire support 4 is transferred to the wheel 8.

In FIG. 6 shows the sofa bed in the unfolded state.

In FIG. 7 shows the sofa bed in the unfolded state, describing parts of the structure of the mechanism and the sofa bed.

In FIG. 8 shows the transformation mechanism "dolphin" without the first and second guides 5 and 6.

The transformation device for the sliding part-sleeper of the sofa bed consists of a transformation mechanism of the "dolphin" type 3 (Fig. 8) with a system of movable wheels and guides. The first guide 5 is a support for the transformation mechanism "dolphin" 3 with a retractable part (sleeper) 2 in the "folded" position. And also along it, the mechanism during rolling out is lowered and first touches the transport 7, and in the process of transformation and the support wheels 8 of the floor. In the process of folding said guide 5 allows you to raise the mechanism to a level at which the bottom of the side 9 of the sofa comes to the desired height of the supports. Thus, the first guide 5 serves to lower the front part of the mechanism during the unfolding process and to raise it during the folding process.

The second guide 6 is used to lower the rear part of the transformation mechanism "dolphin" 3 in the process of unfolding and lifting in the process of folding. At the same time, the shape of the guide determines the trajectory of the wheel 11, serves additionally to bypass the parts of the mechanism in its rear part from the first guide 5 during the transformation process and allows the rear part of the dolphin transformation mechanism 3, in turn, to lower (and when addition - rise) to the desired level. For this, a straight section is made, which turns into a slope at the moment when the parts of the mechanism have already passed the first guide 5, and only after that does a smooth lowering occur. The second guide 6 also serves as a stopper to limit the extension of the mechanism when unfolding.

The movement along the first guide 5 is carried out by the wheel 10, the movement along the second guide 6 is carried out by the wheel 11.

The device operates as shown in Fig. 1-7: User grabs drawer side 9 from below and begins to pull it out towards himself. After a short application of a small effort, the transformation mechanism "dolphin" 3 rolls along the first guide 5 until the contact of the transformation mechanism "dolphin" 3 with the hollow wheel 7. Further, before the transformation into a sleeping place (Fig. 6, 7) of the mentioned mechanism after full extension, the front part of this mechanism rests on wheel 7, and the rear part rests on wheel 11. After the rear part of this mechanism passes through the first guide 5, a slope is provided in the second guide 6, along which the mechanism goes down and is fixed in the front part of the second guide 6.

After that, the retractable part (sleeping bag) 2 begins to be lifted up and there is a transition from the transport wheel 7 to the thrust wheel 8, kinematically connected with the sleeping bag 2 transformation mechanism.

After unfolding, mechanism 3 rests on wheel 11 and wheel 8, and its sleeping bag rests on frame 9 and forms a single bed with seat 1.

The presence of a certain form of guides and movable wheels associated with the movement of the rods of the "dolphin" mechanism allows you to raise the structure to the level required to match the sliding part of the sleeping bag and the seat of the sofa bed in height and ensure a comfortable sleep. Thus, the transformation of the sleeper of the sofa-bed with high supports 4 (from 120 mm to 150 mm) with the possibility of folding the wheels and eliminating their contact with the floor in the assembled state of the sofa is ensured.
