Abstract

Articulated chair, which constituted from two rigid sides with upper armrest, a seat between these rigid sides, a folding back and a front and retractable footrest, under seat and which is related to a link mechanism which is also the support structure assembly of the chair on the floor structure that is shorter and narrower than the chair body, characterized in that in correspondence with the bottom of the rigid sides of the chair are provided respective legs that are positioned to limit both laterally and frontally, legs that in the rest position of the chair are slightly off the ground to establish support if rollover trend towards both laterally and towards the front of the chair itself.

Description

Articulated armchair

Object of the invention

The present invention relates to an armchair articulated that includes a folding backrest from a position approximately vertical to a later position and practically horizontal, and a footboard or retractable footrest, counting on rigid sides whose upper part goes located the corresponding armrests, settling between the lower part of the seat and these sides the corresponding articulated structure that allows the commented dejection of the backrest and the slapping or exit towards the front of the footboard or footrest.

The object of the invention is to avoid the risk of I turn to the armchair when a load is made or push on one of the sides or the front part of it armchair.

Background of the invention

As is known, articulated armchairs or Ergonomic, which are used both at a particular level and in hospital clinics, etc., are generally constituted by rigid sides in which the corresponding upper armrests, between whose sides it goes located the seat itself, as well as a folding backrest from the almost vertical position to a position of virtually horizontal dejection while ahead and in correspondence with the bottom of the commented seat goes arranged a footrest that unfolds forward in the moment when the backrest is folded back, all based to an articulated structure or mechanism established under the set that form the seat and backrest.

The metallic and articulated structure referred to with previously it also constitutes the support of the armchair assembly, so that conventionally those structures are narrower that the width of the chair itself, in addition to being substantially offset backwards from the front of it.

These characteristics give rise to a chair instability that tends to tip over when make a load on one of its sides or on the front part of the seat, which poses a risk to the occupant and / or patient, especially when the chair is used in hospital clinics.

Description of the invention

The articulated armchair that is recommended, based in the characteristics referred to above, it presents the particularity that in correspondence with the bottom and front of the rigid sides of the armchair body, have provided complementary legs, which are laterally to the limit of those sides of the body of the armchair and of the own one front, so that the problem that this type of armchairs in certain body positions tend to overturn lateral or forward, it is perfectly resolved by the existence of those front legs and especially for the concrete positioning of them, so that those legs They are designed so that in normal position of use do not touch the floor and allow the mobility of the backrest and footrest through its mechanisms, but at the moment the armchair starts the tipping movement to one side or the other or towards in front, there is immediate support on the ground through the commented supplementary legs, ultimately preventing the overturning of the armchair. That is, the forces between said legs Supplementary and supports corresponding to the structure general of the articulated armchair mechanism, are distributed and as a consequence, any lateral movement with tendency to return the chair itself, even any movement forward also tending to overturn, as a result of weight shift that can occur in certain circumstances on the chair itself.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a view according to a general perspective of an articulated armchair with legs corresponding to the novelty characteristics of the invention.

Figure 2.- Shows a perspective view side of the same chair represented in the previous figure, with the backrest folded back and footrest extended towards in front of.

Figure 3.- Shows a perspective view front and bottom of the chair itself represented in the figures previous, showing how the support structure for the armchair It is narrower than the body of the chair itself, and shorter than this one, so that the problems that support structure has of the chair are solved by the supplementary legs that can be seen frontally in this figure.

Preferred Embodiment of the Invention

Based on the referred figures, you can observe a conventional armchair that is foldable and that includes two rigid sides (1), a folding backrest (2), and a front and bottom footrest (3) retractable, leaving it for under the corresponding seat (4) of the armchair, with the particularity that on the top of the sides rigid (1) the corresponding armrests (5) are formed, All this as conventional.

In addition, this type of armchairs counts inferiorly and in a hidden way with a structure (6) in which the corresponding mechanism for dejection is established both of the backrest (2) and for the extensibility and scaling of the footrest (3), structure (6) that also constitutes the means of support or support of the armchair assembly on the ground, and that as you can see in figure 3 is smaller and shorter than the armchair's own body.

Well, the novelty of the invention is based on that on the bottom and front of the rigid sides (1) two legs are provided (7) whose length is such that in the resting position or normal use of the chair do not rest on the floor, said legs (7) being stiffened by means of a crossbar (8), as shown in figure 3.

That lower level of the legs (7) so that rest on the ground, allows the movements of the mechanism to the folding of the backrest (2) and the recoil or extensibility of the footrest (3).

Based on the legs (7) that are located at limit in the frontal direction and the limit in the lateral sense, as can be seen in the commented figures, they establish that in the moment that the chair tends to overturn overweight in one of the lateral or in the front, immediately lean on such legs (7) and prevent its overturning, all as a consequence that such legs (7) constitute a supplementary means of support moved towards the previous part, being necessary to make a intentional maneuver to carry out the overturn of one's own armchair.

Claims (1)

1. Articulated armchair, which being constituted from two rigid sides with upper armrests, a seat between those rigid sides, a folding backrest and a front and retractable footrest, located under the seat and which is related to an articulated mechanism that also constitutes the support structure of the armchair assembly on the floor, structure that is shorter and narrower than the armchair body, is characterized in that in correspondence with the lower part of the rigid sides of the armchair, two legs are provided that are located at the limit both laterally and frontally, legs that in the chair's rest position are slightly separated from the floor to establish supports in case of a tendency to overturn both towards the side and towards the front of the armchair itself.
