Abstract

Perfected joint for sofa beds, characterized mechanism because the mechanism deployed position bed, a plate (1) is incorporated in tension that functions as a strut of the workpiece held-back cushions (2) preventing that in that position the ground contact of said pads is produced; because when the folding mechanism is to move from the bed position to a sofa position, a plate (3) moves to the subject-piece seat cushion (4) to prevent friction occurring or deformation of said pads; and that when the mechanism is folded in the sofa position, the plate (1) working in compression, exerts a thrust on the subject-back cushions (2), inclining to adopt a position adjusted to the user's back, that rests on them.

Description

Improved mechanism for articulation of sofa beds.

Object

The object to which the invention relates to Protects in this Utility Model, it consists of a Mechanism perfected for sofa bed articulation, that is, for usable furniture interchangeably and potentially as sofas (in retracted or folded position) or as beds (in extended or deployed position).

Background

The current high price of the volume built in housing conditions the need for maximum use of the inhabited space, inscribing in this consideration the creation and use of transformable furniture, so that it is susceptible to double and even multiple use.

One of the most characteristic furniture of the group of the dual use is the sofa bed that, in its multiple variants, has gained general acceptance and reaching great diffusion by the accused practical difference of its two positions of use: as a sofa, during the day and as a bed at night.

The transformation of one piece of furniture into another (which, in this specific case, must be done daily) presents a series of requirements for greater functionality, among the which can be included:

The minimum occupation of space, in position folded (sofa).

The least possible displacement of components complementary (eg cushions).

The greatest effort economy in the manual transformation (ergonomics), through compensation mechanical (balanced, springs).

The structure of the known sofa bed is mostly formed by steel plates that configure frames rigid soldiers and articulation knots between them, to facilitate the transformation of use by folding some about others.

Within these generic characteristics, they are known numerous embodiments that meet in proportion variable the functional requirements previously stated and that for that reason, they are perfectible in partial aspects that allow a greater degree of compliance with these requirements.

Description of the invention

The purpose of the invention that constitutes the The purpose of this Utility Model is to eliminate some functional disadvantages of the known object, having been designed and developed according to this objective Priority

According to one of the improvements introduced and claimed in this Utility Model, the general structure of the mechanism, responds in broad terms to the known design of these mechanisms, in terms of their composition and operation.

However, the perfected mechanism that constitutes the object of this Utility Model, presents improvements Structural that bring new benefits and effects on what is already known.

Among these improvements can be noted the following:

With the mechanism deployed in bed position, it incorporates a plate that working on traction, It works like a brace of the cushion-clamp piece of the backrest preventing that in this position the contact with the floor of the cushions mentioned.

When the mechanism is is folding to move from the bed position to the position sofa, a plate displaces the cushion-clamp piece of the seat to avoid friction or deformation of The cushions mentioned.

Finally, when the mechanism is folded in the sofa position, a plate working under compression, exerts a push on the backrest cushion holder, tilting it so that adopt a position adjusted to the user's back, so that rest comfortably on it.

As a peculiarity of mechanism, it should be noted that all its articulated joints are made using screws as fixing means, so that in the event of breakage or deformation of any of the structural elements, can be easily replaced with parts originals

Another advantage to highlight is that thanks to this system of displacement the backrest allows to be 10 centimeters higher.

Brief description of the drawings

To complement the description of the invention and facilitate the interpretation of formal characteristics, structural and functional of its object, drawings are accompanied in those that schematically represent different aspects of a preferred embodiment of the perfected mechanism for sofa bed articulation, which constitutes the object of this Utility Model. In these drawings:

- Figure 1 represents in perspective the mechanism structure assembly, deployed in position bed.

- Figure 2 shows a side elevation view of the mechanism deployed in bed position.

- Figure 3 shows in side elevation the mechanism in intermediate position, folding to pass from the Bed position to sofa position.

- Figure 4 shows in side elevation the folding mechanism in sofa position.

Description of a preferred embodiment

To clearly show nature and the advantageous application scope of the perfected mechanism for the sofa bed joint that constitutes the object of the claimed invention, the following is described arrangement of structural elements, referring to the drawings that, for representing a preferred embodiment of this object, for informational purposes, should be considered in its broader sense and not as limiters of the application and the content of the claimed invention.

The general structure of the mechanism responds in broad terms to the known design of these mechanisms, as far as to its composition and operation.

However, the perfected mechanism that constitutes the object of this Utility Model, presents improvements Structural that bring new benefits and effects on what is already known.

Among these improvements can be noted the following:

- With the mechanism deployed in the bed position, a plate (1) is incorporated which, working on traction, works as a brace of the cushion holder part of the backrest (2) preventing that, in said position, the contact with the floor of the cushions mentioned.

- When the mechanism is folding to move from the bed position to the sofa position, a plate (3) move to the seat cushion holder part (4) to avoid friction or deformation of the aforementioned cushions

- Finally, when the mechanism is found folded in the sofa position, the plate (1) working at compression, exerts a push on the cushion holder  of the backrest (2), tilting it to adopt a position adjusted to the user's back, so that it rests comfortably on he.

- As a feature of the mechanism, it is possible point out that all articulated joints are made by screws as fixing means, so that in the case of there is a breakage or deformation of any of the elements structural, can be easily replaced with parts originals

Claims (1)

1. Improved mechanism for the articulation of sofa beds, characterized in that with the mechanism deployed in the bed position, a plate (1) is incorporated which, working in traction, functions as a brace of the support-cushion piece of the backrest (2) preventing that, in said position, contact with the floor of said cushions occurs; because when the mechanism is folding to move from the bed position to the sofa position, a plate (3) displaces the seat cushion holder (4) to prevent friction or deformation of said cushions; and because when the mechanism is folded in the sofa position, the plate (1) working under compression, exerts a push on the backrest cushion holder (2), tilting it so that it adopts a position adjusted to the user's back, which support on them.
