RU2146488C1 - Convertible upholstered seating and lying furniture equipped with retractable member - Google Patents

Abstract

FIELD: production of furniture, in particular, convertible armchairs and sofas. SUBSTANCE: convertible furniture has carcass, sides rigidly attached to carcass, movable back and seat which are secured to carcass for rotation relative to horizontal pin and forward and backward displacement during conversion, retractable member used for lengthening seating and lying surface and provided with end support, and cushion adapted to be positioned on retractable member. Carcass is made in the form of hollow casing adapted for receiving cushion, when furniture is converted into seat. Seat and back have carcass with rigid base and cushion positioned onto base. Retractable member guides are fastened under seat rigid base. Retractable member is formed of rigid boards with restrictor at end part. Cushion adapted to be put onto retractable member is made detachable. EFFECT: simplified construction, wider operational capabilities and increased convenience. 4 dwg

Description

 The invention relates to furniture production and can be used in the manufacture of chair beds and sofa beds. Such furniture is widely used in the equipment of premises with a limited area, as it allows it to be used economically.

 Transformable furniture is known, consisting of a rigid frame on which sections of the back and seats are attached, connected by a click-clock transformation mechanism that transforms the product from the “sofa” position to the “bed” position and vice versa. (Rumyantsev R.P. Production of upholstered furniture. M: Forest industry, 1979, p. 97-99).

 The disadvantage of this type of transformable furniture is the possibility of increasing the size of the surface for lying only by adding the surface of the back to the seat surface.

 Known convertible upholstered furniture for sitting and lying, complemented by a retractable element, comprising a frame, sidewalls rigidly fixed to it and movably mounted back and seat, rotatably connected relative to the horizontal axis with movement back and forth during transformation, a retractable element extending the surface for sitting and lying, with an end support and a pillow mounted on it, and the furniture frame is made in the form of a hollow box in which this pillow is stored in the "sitting" position (SU 1509029 A1, 09/23/98 nine).

 The disadvantage of such furniture is the complexity of its manufacturing technology.

 The technical result achieved by the implementation of this invention is to simplify the technology of manufacturing furniture and increase its strength when using wooden structures (traditional and most accessible to Russian furniture manufacturers).

 The specified technical result is achieved by the fact that in a convertible upholstered furniture for sitting and lying, supplemented by a retractable element containing a frame, sidewalls rigidly fixed to it and movably mounted back and seat on it, connected rotationally with respect to the horizontal axis with forward and backward movement during transformation, a sliding element extending the surface for sitting and lying, with an end support and a pillow mounted on it, and the furniture frame is made in the form of a hollow box in which in the position "d For the seat ", this pillow is stored, according to the invention, the backrest and seat have a frame with a rigid base with a pillow fixed on top, guides for a sliding element are made under the rigid base of the seat, made in the form of rigid shields with a stop at the end, and a pillow mounted on a sliding element made removable.

 The invention is illustrated by drawings, where in FIG. 1 shows the construction of furniture in the "sitting" position in FIG. 2 - furniture with a raised seat; in FIG. 3 - furniture in the "lying" position; in FIG. 4 - seat assembly with a support extending the surface for lying, with vertical cuts.

 The furniture has a frame 1, on which the sidewalls 2 are rigidly fixed, with the help of a lock 3, a back 4 and a seat 5 are rotated relative to the horizontal axis with movement back and forth during transformation. Position 6 is the end support of the extension surface. Position 7 - removable pillow. Position 8 is a retractable element that extends the surface for lying, made in the form of rigid shields 9, for example, of plywood, resting on a support 6 in the form of a bent arc protruding above the surface of the shields and providing emphasis on the removable pillow 7 installed in the "lying" position . Position 11 - limiter. Position 12 - seat frame. Position 13 - guides.

 The furniture is transformed from the “sitting” position to the “lying” position as follows: remove the removable pillow 7 from the frame 1, lower the backrest 4, pulling the seat 5, lower the seat 5, extend the element extending the surface for lying 8 and lay a removable pillow is placed on it 7. The transformation of furniture from the “lying” position to the “sitting” position is performed in the reverse order.

 By extending the extension element in the “sitting” position, additional comfort for resting the legs can be achieved. Also in this position, the furniture can be used as a safe crib.

 The proposed furniture is stable and easy to use.
