Description

Recliner armchair

Object of the invention

The present invention relates to an armchair reclining, in which your back is likely to fall towards outside and your seat move forward, so that the user of it can adopt two limit positions, one with its back next to the vertical and another considerably lying as well like any intermediate position chosen by it.

The object of the invention is to achieve an armchair recliner of maximum structural simplicity, which changes easily position at the request of the body's own mobility of the user.

The armchair can be used interchangeably private or public use, in the latter case implantable in rooms of shows, cinemas, conference rooms, etc.

Background of the invention

There is a great diversity of seats on the market with the aforementioned applications, which for the most part they present as a common denominator a rigid structure, how It only allows a certain body posture for the user. The limitations that from the point of view of use offer these rigid seats are obvious.

There are also different types of seats reclining, which allow the degree of backrest inclination and sometimes also allow positional changes in the seat, but all of them present their once as a common denominator a great structural complexity derived from the necessary mechanisms for its mobility or change of position.

On the other hand these devices, in many cases of doubtful efficacy, they generally have a remarkable volumetry, which often makes hiding with the upholstered, being necessary to place them in a special cabin internal, so that such mechanisms are duly isolated and not pose a risk to the users of the armchair or to the staff responsible for cleaning it.

Description of the invention

The reclining armchair that the invention proposes solves the problem fully satisfactorily previously exposed, constituting a solution of maximum structural simplification, reduced cost and maintenance practically null, in which the mechanisms that allow its mobility occupy a minimal, practically negligible space, which the space occupied by the elements does not increase the absolute basic of the armchair, that is to say for its seat, backrest and armrest

To do this and more specifically said armchair it is structured from a fixed frame, in which two sides participate, which will preferably remain Integrated armrest armrests, conveniently lateral stiffened together by one or more crossbars conveniently located so that they do not interfere with the moving elements.

In the postero-superior zone of said frame, that is to say of the sides that constitute it, is establishes a transverse tilt axis for the backrest, axis which is located substantially above the lower edge of the itself, and on said lower edge in turn joins in turn the seat, so that backrest and seat form a dihedral of variable angle

To the mentioned stiffening crossbar, established between the two sides of the fixed frame, in the anterior area of the same, a bushing is oriented, oriented in the direction anteroposterior and centered disposition, in the which plays a stem with its free posterior limb and with its anterior limb articulated jointly to a crossbar in the area middle of the seat, so that the latter is also movable in the antero-posterior direction, accompanying backrest movement, at the same time as you can swing in accordance with the kinematic chain that configures with the mentioned support.

Finally and according to another of the characteristics of the invention it is provided that the structure rigid that constitutes the base of the seat is an articulated a anterior half-frame, assisted by a pair of side springs of torsion, so that the anterior limb of the seat is susceptible to swinging elastically and downward with with respect to the rest of said seat, enhancing the comfort of the same and, consequently, the comfort of the armchair in its set.

The mobile structure of the armchair is maintained stable in any position by simply rubbing your upholstered, and in use situation remains stable in turn any position chosen by the user, depending on their own body position, being able to carry out any time change in it without further pressing back with the area upper back, or pushing the seat back.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a perspective view of a recliner armchair made in accordance with the purpose of the present invention

Figure 2.- Shows a side elevation view and in section of the armchair of the previous figure, in a situation of maximum dejection for your support.

Figure 3.- Shows, finally, a detail in perspective of the base structure of the seat, at the level of the area of articulation between the two integral parts of it.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as in the recliner that the invention proposes a frame participates, based on two sides (1), which in the practical embodiment example depicted in the figures adopts a trapecial configuration, isoscelic and inverted, but that can adopt any other configuration, in which they remain integrated the respective armrests (2), laterals (1) that are stiffened by at least one crossbar (3) that confers on frame adequate structural strength.

To the postero-superior zone of the lateral (1) a tilt shaft (4) is coupled that crosses the backrest (5) at a point substantially distanced from its edge bottom, as seen especially in figure 2, so that said backrest (5) is capable of tilting within the frame (1).

At the lower edge of the backrest (5) joins articulated, by means of a coupling (6) type hinge or similar, the seat (7), whose base structure (8) is set to in turn, in a substantially offset position forward, a crossbar (9) integrated in the seat structure, to the which joins a rod (10) articulated at its midpoint, axially movable in a bush (11), of considerable length, fixed jointly to the crossbar (3) at its midpoint, preferably by welding, so that the crossbar (9) is likely to move forward and backward, together with the seat (7), by displacement telescopic rod (10) inside the bushing (11), and also said seat (7) is able to swing through of the articulated joint between said crossbar (9) and the stem (10), simultaneously to the backrest tilting (5), and that, as seen especially in figure 2, the three points crankshaft cited, that is, the tilt axis (4) of the backrest, articulated joint (6) from backrest to seat (7), and crossbar (9) of the latter, are located according to the imaginary vertices of a deformable triangle.

This implies, as previously stated, that from a situation of minimum backrest inclination (5), as shown in figure 1, mobilizing the user own body on the armchair automatically gets, without need to act on any mechanism, any change of position it deems convenient, up to the maximum situation backrest shown in figure 2.

Finally and as a complement to the above exposed, it is provided that in the base structure (8) of the seat (7) participate a front half-frame (12) articulated jointly to the crossbar (9), settling on the ends of said crossbar (9) two torsion springs (13) which relate the half-frame (12) to the rest of the structure (8) of the seat and that, given an overexertion determined by the load body of the user on the front area of the seat (7), they allow that limb to swing slightly towards below, further enhancing the comfort of the armchair.

Claims (2)

1. Recliner armchair, which can be used for private use as well as for public use, in showrooms, cinemas and the like, in which a fixed frame participates in which its armrests are integrated and in which the seat and seat are established backrest of the armchair, characterized in that between the sides of the frame, in correspondence with the postero-superior area of the same, a transverse tilt axis for the backrest is established, which is substantially raised with respect to the lower edge thereof and which allows the tilting of said backrest with respect to the frame, while said lower edge of the backrest joins the seat articulatedly, which in turn incorporates in its base structure a transverse bar, substantially offset forward, to which midpoint joins articulated a rod that plays telescopically inside a bushing in solidarity with the midpoint of a crossbar that stiffens both beats rails of the fixed frame and that is located in the vicinity of the anterior edge of said laterals, so that said seat is capable of moving in the antero-posterior direction and tilting simultaneously to the way the backrest does, both elements configuring a dihedral of variable amplitude depending on the user's body position. 2. Reclining armchair, according to claim 1, characterized in that an anterior half-frame participates in the base structure of the seat, articulated jointly to the rest of the structure through the aforementioned transverse bar, bar on whose ends two torsion springs are established that relate the semi-frame with the rest of the base structure of the seat and that allow a certain downward tilt of said half-frame when the user acts with his own body load on the front limb of the seat.
