ES2315213A1 - Backrest-elevable headrest for sofa-bed with seats and retractable backings (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Backrest-lift-up headrest for sofa-beds with seats and retractable backrests, constituted in practice by two plates (1) of rectangular configuration. Each plate (1) has two lateral grooves (2) through which runs a rod (3) with a 90º bend. The rod (3) is connected at one end to the plate (1) thanks to a vertical projection (4) that has the latter, both being fixed by nuts (5), while the other end of the rod (3). ), that is to say, the vertical part that remains below the plate (1) is fixed under pressure to two ferrules (6) that have been welded for this purpose in the upper part of the backrest (7) of the structure of the sofa- bed. To attach the headrest to the structure of the sofa-bed, simply insert the stem (3) into the holes of the sleeves (6), being thus fixed and ready for use. To make it difficult for the rod (3) to move vertically, a number of studs (8) are placed in the lower part of the bushing (6). (Machine-translation by Google Translate, not legally binding)

Description

Liftable headrest-backrest for sofa beds with seats and backrests retractable.

Object

The object to which the invention relates to protects in the present invention patent consists of a "Liftable headrest for sofa beds ", that is, for usable furniture indistinctly and potentially as sofas (in a retracted position or folded) or as beds (in extended or deployed position).

Background

The current high price of homes, conditions the need for maximum use of space inhabited, registering in this consideration the creation and use of transformable furniture, so that it is susceptible of the greatest possible use.

One of the most characteristic furniture is the sofa bed This piece of furniture has the comfort of offer seating places, at the same time as hiding in your interior a large bed to convert any living room or cabin in an improvised bedroom.

When space is scarce, as is usually the case Once again, the sofa bed is the perfect ally. The changes that are emerging in the traditional family structure and the high floor prices cause you to bet on one of these versatile furniture to live in small apartments or studies.

Today we find a lot in stores of models to meet the needs of all types of customers. There are models with single beds, but also type marriage, as well as small armchairs and poufs that, in a space reduced, they incorporate small beds that will support the unforeseen

Apart from the obvious size classification, we can distinguish the sofa beds by virtue of the opening, either this frontal, lateral or elevable. If we take out the bed in front, the mattress may be hidden on the back of the sofa or on the seat.

Given the great functionality they play and use which is made of them, incorporation into the same new advantages and solutions that make this type of furniture a better solution for its users.

The main drawback presented by sofa bed of the type of so-called "living room" in which the seat and backrest once deployed are under the bed, is that said backrest must be of limited height to allow the unfolding of the sofa bed, thus having poor support the user's head and hence the utility of the headrest liftable

Description of the invention

The purpose of the invention that constitutes the object of the present invention patent consists of the elimination of some structural problems of the known object described in the previous section, having been designed and developed according to this priority objective.

According to the perfection introduced and claimed in this patent, the general structure of the mechanism, responds in broad terms to the known design of these mechanisms, in terms of its composition and operation.

For this, the head restraints are constituted by rectangular paths of rectangular configuration and nature metallic Each plate has two lateral grooves along the that runs a rod with a 90 ° bend.

The stem is related by one of its ends with the plate thanks to a vertical highlight that presents this last, both being fixed by nuts, with the ability to I turn around that point, acting in practice as hinges. He other end of the stem, that is, the vertical part that remains for under the plate is fixed to pressure to two bushes that have been soldiers to that end on top of the back of the sofa bed structure.

For fixing the headrest to the structure of the sofa bed is enough to introduce the stem in the holes in the bushings, thus being fixed and ready for use To make it difficult for the stem to move vertically some prisoners are placed in the part bottom of the bushing, which has a groove in its part bottom so that prisoner makes contact with both the cap as with the stem.

Once the headrests are fixed to the sofa-bed structure these have a 90 ° turning capacity to that the user can graduate at will. Thanks to headrest is achieved in height gain in the backrest of the sofa bed, which is a real innovation in this type of furniture, which solves the structural deficiency of these sofa beds that hide seats and backrests under the bed.

Brief description of the drawings

To complete the description of the invention and facilitate the interpretation of formal characteristics, structural and functional of your object, are accompanied by drawings in which different aspects of a preferred embodiment of the liftable headrest for sofa beds that is the object of this patent. In these drawings:

- Figure 1 represents an exploded view of the upper part of the sofa bed structure with the headrest in down position.

- Figure 2 corresponds to a view previous where the headrests to the backrest are already related of the sofa bed structure.

- Figure 3 shows the previous views with headrests in an upright position, that is, when you are making use of them.

- Figure 4 represents side details of the previous views.

Description of a preferred embodiment

To clearly show nature and the scope of the advantageous application of headrest-lift that constitutes the object of the claimed invention, its description is described below. structure referring to the drawings that, to represent a preferred embodiment of said object, with character informative, should be considered in its broadest sense and not copied limiters of the application and the content of the invention claimed.

To do this, the headrest-headrests are made up of flat paths (1) of rectangular configuration and nature metallic Each plate (1) has two lateral grooves (2) through which runs a rod (3) with a 90 ° bend.

The stem (3) is related by one of its ends with the plate (1) thanks to a vertical projection (4) that presents the latter, being fixed both by nuts (5), capable of turning at that point, acting in practice as of hinges. The other end of the stem (3), that is, the part vertical that remains below the plate (1) is fixed under pressure at two bushes (6) that have been welded to that end in the part upper backrest (7) of the sofa bed structure.

For fixing the headrest to the structure of the sofa bed is enough to introduce the stem (3) in the holes of the bushings (6), thus being fixed and ready for use To make it difficult for the rod (3) to move vertically some prisoners (8) are placed in the lower part of the bushing (6), which has a groove (9) in its lower part so that said prisoner makes contact (8) both with the bushing (6) as with the rod (3).

Once the headrests are fixed to the sofa-bed structure these have a 90 ° turning capacity to that the user can graduate at will. Thanks to headrest is achieved in height gain in the backrest of the sofa bed, which is a real innovation in this type of furniture, which solves the structural deficiency of these sofa beds that hide seats and backrests under the bed.

Claims (1)
