Description

DESCRIPTION

Mechanism for relaxation chair

Object of the invention

The object of this invention is to provide the market with an improved reclining and relaxation system for armchairs, sofas, etc., with which to achieve maximum relaxation for the user by raising the footrest higher than the conventional one.

The industrial sector to which this invention belongs is the manufacture of furniture and rest elements.

Background of the invention

There are various reclining systems on the market for relaxation in armchairs and the like, all of them made up of similar elements, such as those disclosed in the following documents:

Document ES1053578U discloses a structure for a reclining seat, the back of which can be reclined backwards by tilting and simultaneously raising the seat body, with support means for a footrest projecting towards the front, which provides a slight elevation.

Document ES2325367T3 discloses a reclining chair that has a mechanism that raises and extends the footrest simultaneously, which consists of linearly extending the sliding profile elements allowing some small pivoting and/or translation movements, to perform a smoother operation of the mechanism. In addition, it avoids the "scissor effect". Document ES2609252T3 presents assisted articulation mechanisms for a tilting and sliding recliner chair in such a way that the sequence ensures that the footrest extends substantially before the backrest begins to recline.

Document ES2767134T3 proposes a reclining chair close to a wall, which can be moved by means of a special seat back adjustment mechanism from a vertical position to a horizontal position, without the backrest coming into contact with the wall. This is achieved in such a way that when the backrest is tilted in a direction towards the wall, the seat moves forwards at the same time.

Document ES2399840T3 shows an articulation mechanism for a reclining chair that provides improved movement between sitting, reclining and fully reclining positions. To fully recline the chair, the user applies a force to the backrest, which acts on the seat mounting plate and lift link arm and causes the seat to rise and move the link to the full recline position. The rearward motion causes the rear of the seat mounting plate and lift links to rise at a higher rate than the front portions. In this way, the orientation of the lifting link arm and, therefore, of the seat is close to horizontal.

On the internet, they also market various type systems such as the above, being able to see as an example those disclosed by the company Subiñas (https: //www.subinas.es/mecanismosrelax-para-butacas-y-sofas.asp).

The fundamental difference of the mechanism that is presented with respect to the state of the art lies in the fact that the proposed reclining system provides a greater elevation of the footrest than the one usually found on the market, reaching a position in which the feet are at the same height as the heart, generating a sensation of weightlessness and maximum comfort in the user, as well as great stability of the chair and the security that once the backrest is reclined, if the user stands up, said backrest remains fixed on your site; thereby achieving a great technical advantage over conventional systems.

Although the invention disclosed in document ES2399840T3 proposes to reach a recline close to horizontal, the system to achieve it differs completely from the improvement proposed here. While in said document ES2399840T3 the force exerted by the user is used to reach the maximum reclining position, the object of this invention is characterized by having two additional legs in a strategic position in the support and reclining mechanism, entering in operation once the recline and elevation system has been fully deployed, and that not only causes the extra elevation of said footrest, but also stability of the chair, while preventing the backrest from returning to its initial position.

Explanation of the invention

This reclining system is made up of a standard reclining mechanism with the peculiarity of the insertion of two plates, one on each side of the mechanism, which have a wheel at their end. In this way, two legs are formed (plate with wheel) that will allow the movement to tilt. That is to say, this invention materializes in a modification in the reclining mechanism for a conventional and habitual relaxation in the market.

The conventional reclining-relaxing mechanism is not going to be the object of a detailed description of each of its parts, since its operation with its various possible variants is widely known in the sector and is not the object of this invention. However, its movement as a whole is going to be referred to, since it is necessary to understand the improvement advocated in this invention, but not its movement piece by piece.

To better understand the functionality that this system provides, it is necessary to understand the movement of the conventional recline-relax system. This movement is mainly divided into two parts: first, it performs the opening movement of the footrest, thanks to the extension of the scissors that make it up, and then it performs the forward movement where the backrest reclines and the seat moves slightly forward. ahead.

The main advantage provided by the introduction of these wheeled plates is the stabilization of the system. In their initial position, the plates are in a nearly horizontal position with respect to the ground plane, without touching it. When the system begins its opening movement, the footrest of the upholstered furniture begins to rise, leaving the stabilizing legs still in their initial position. Then, continuously, the seat moves forward, simultaneously with the reclining movement of the backrest, the stabilizing legs start to move.

At that moment, the legs begin to descend until the wheel touches the ground, stabilizing the system throughout the remaining travel. These wheels not only provide extra elevation on the footrest part, but also provide great stabilization, leaving the end user feeling weightless for optimal rest and relaxation.

In addition, with the stabilization and elevation provided by said element, the end user can sit forward when the mechanism is fully open without the sofa or armchair rocking forward. In this way, one of the main drawbacks of conventional relaxation chairs is solved.

A significant aspect, and that differentiates this system from others, is that all the movement is carried out with a single motor, achieving a continuous sequence of movements. In addition, this system can be incorporated not only into armchairs, but also into sofas and composition modules with a chaise longue.

Brief description of the drawings

To complement the description made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, where the following has been represented for illustrative and non-limiting purposes.

Figures with the conventional recline-relaxation system are shown first, followed by those related to the maximum elevation relaxation system. All this with the aim of capturing the differentiation and practicality of the new system.

In addition, the abscissa and ordinate axes have been incorporated so that the difference in movement described by both systems can be more easily appreciated.

Figure 1.- Shows a profile view of a sofa module with the standard recline-relaxation system in its original position. It can be seen how the mechanism (1) is completely closed.

Figure 2.- Shows a profile view of a sofa module with the standard recline-relaxation system incorporated. In this figure it can be seen how the mechanism (1) has already completed its first movement: the total opening of the footrest.

Figure 3.- A profile view of the conventional recline-relaxation system with all of its movement performed. With respect to figure 2, it can be seen how the mechanism (1) has made its forward movement and the backrest has been slightly more reclined.

In these first three figures, the movement of the conventional recline-relaxation system has been shown. The figures corresponding to the maximum elevation relaxation system are shown below.

Figure 4.- Represents in a profile view the maximum elevation recline-relaxation system in its original position. The wheels corresponding to the stabilizer legs (2) are at a small distance from the horizontal axis, so they are not in contact with the ground. In addition, the mechanism (1) is completely closed.

Figure 5.- Shows the same situation of the maximum elevation recline-relaxation system as figure 4, but in a perspective view. In this view, it can be seen more clearly that the wheel is not in contact with the ground, but is at a small distance.

Figure 6.- Shows a profile view of a sofa module with the maximum elevation recline-relaxation system semi-open. This figure represents just the moment in which the opening movement of the mechanism (1) ends, where it can be seen that the stabilizer leg (2) continues in its original or initial position.

Figure 7.- The same situation as figure 6 is represented, but from a perspective view of the system.

Figure 8.- Shows the final position of the maximum elevation recline-relaxation system. The mechanism (1) is completely open, with its opening and forward movement carried out, and the stabilizing legs (2) are in contact with the ground giving the system greater stability, in addition to raising it in the footrest part to achieve a feeling of weightlessness in the end user. Thanks to the axes incorporated in the figures, the extra elevation that this system provides can be more easily appreciated, thus differentiating itself from the conventional system. As seen in the figure, in this new system the feet are at the same height as the heart, generating the sensation of weightlessness.

Figure 9.- Shows the same situation as figure 8, but with a perspective view in order to be able to visualize both sides of the maximum elevation relaxation system in its final position.

The main components that stand out in the different figures are:

(1) Standard recline-relax mechanism

(2) Stabilizing Leg

Preferred embodiment of the invention

According to the explanation of the invention and the figures presented, it can be seen how the improvement introduced in the conventional reclining-relaxation systems is constituted from incorporating in the reclining mechanism (1) on both sides of the frame structure, Following the last articulated section, a plate with a wheel at its lower end rolls like a leg (2) (fig.4).

The structure of the proposed system consists of a backrest, a seat and a footrest, with their corresponding frames and fastening pieces on each of the sides, a reclining articulation system and seat elevation, supported by a traditional scissor-like structure. on each side with a series of profiles articulated with each other, following the profile that supports the structure or scissors, a leg-like section (2) made up of a plate and a wheel.

The system works as follows:

In the initial position of the chair, when the reclining mechanism is fully closed (fig.4), the stabilizing legs (2) form a certain angle with respect to the scissors without the wheel being in contact with the ground, but rather about 0.5-2.5 cm from it.

By activating the motor (not shown in the figures), by means of a button, the sequence of raising the footrest, the movement of the drawer where the seat rests that causes it to move forward, and the reclining of the backrest are carried out continuously. . When said opening movement of the mechanism (1) ends, the stabilizer leg (2) still continues in its original or initial position (figs. 6 and 7). At that moment, the wheel begins to descend, resting on the ground and the plate is placed in a vertical position until it reaches a position almost perpendicular to the ground (80° ± 5°) and thus causes the drawer to rise and the backrest to rise. lie down a little more.

Finally, the final position of the system is reached, when the mechanism (1) is fully open, with its opening and forward movement carried out, and the stabilizing legs (2) are in contact with the ground, giving the system greater stability, raising the part of the footrest and lowering the backrest a little more, to achieve a sensation of weightlessness in the user (figs. 8 and 9).

The entire opening and closing sequence is carried out and controlled by a single electric motor (not included in the figures) through a push button (not included in the figures).
