Definitions
- the present invention consists of a recliner for use in office or home applications, which combines a simple structure, great strength, ease of use and is adjustable to the individual.
- a chair It is desirable for a chair to have the maximum comfort, while the degree of recline by folding is satisfactory, in any case greater than 30/35 °, so that the user's body is placed in a suitable position.
- the chair has footrests and armrests, so that the comfort of the individual is independent of the position that the chair adopts, and preferably a storage tray such as a computer keyboard, a mouse, or a laptop .
- a known type of reclining chair has a foot on it that is positioned an advanced piece forward, articulated by its front end, so that when said articulation is released the seat tilts on the articulation axis.
- This type of structure poses two fundamental problems: first instead large moments are generated with respect to the support foot, which is why it is required that the structure be endowed with great solidity, which negatively affects production costs and the weight of the chair; secondly, the angle of inclination is considerably limited, since said articulated part is required to be partially hidden under the seat, and to be supported on a foot, normally provided with wheels.
- Another drawback is that the center of gravity does not change significantly, so the efforts made by the articulating means and the support foot are greater than recommended.
- the invention that we propose has the object of a reclining chair that overcomes the previously described drawbacks, displacing the center of the seat base proportionally to its folding to maintain the position of the center of gravity of the chair with the seated person, allowing manufacturing Cheaper, maintaining or improving its structural strength, and being more versatile in terms of the degree of abatement possible, without the existence of predetermined positions.
- an adjustable footrest and means to support a tray for the location of, for example, computing devices such as a keyboard, a mouse or a laptop.
- Figure 1 shows the chair of the invention seen from the bottom, in which the support support has been removed for clarity of representation
- Figure 2 shows the chair of the invention from a side view in which a break has been made in the base to illustrate the internal mechanism
- Figure 3 shows the chair of the invention in a slightly folded position, in which, in the rupture practiced, the position of the mechanism is appreciated
- Figure 4 shows a view similar to that of Figure 3 but in a fully folded position
- Figure 5 shows a front view of the chair showing the folding mechanism.
- the chair object of the invention provided with a backrest 2 and a seat base 3.
- the preferred angle of the base plane of the backrest with respect to the base plane of the seat is 100 °.
- FIG. 4 shows a chair support foot on, for example, a base provided with wheels. It is advisable for the support foot to have adjustment means in height, such as elastic and / or pneumatic means, already known from the state of the art, or any other mechanical means, which in any case are outside the scope of this invention.
- the support foot 4 of the chair 1 is jointly connected to a first body 5 mobile with respect to a second body 6 integral to the base of the chair 1.
- Both the first body 5 and the second body 6 have at least two lateral surfaces 7 and 8, and 9 and 10, respectively, each provided with at least one pair of grooves 11 and 12, and 13 and 14 respectively.
- Said grooves are crossed by respective axes 15 and 16.
- the axis may be mechanically common to both sides of the mechanism or be made up of two separate mechanical axes constituting a single geometric axis, therefore we will refer to the mechanical axis. in both as a single axis, even though it could be divided into two parts.
- At least one of said shafts 15 or 16 is provided with a pinion 17 geared on the one hand to a rack 18 integral with one of the grooves 11 or 12 and on the other hand to another rack 19 linked to the grooves 13 or 14.
- the body of the chair 1 can then be moved from an extreme non-folded position to a folded position, for which the movement of the set of elements 1, 2, 3, 6, 9, 10, 13, 14 occurs, and particularly the rack 18 that will force the corresponding movement of the pinion 17, thereby adopting a precise position defined by the effects of the other rack 19 of the fixed element assembly to the base 4, 5, 7, 8, 11, 12, 19. Due to the convergence of the grooves 11, 12, 13, 14 the sliding in turn produces a turn, since all other degrees of freedom of the mechanism are restricted by said position.
- the sliding will be limited by the position of the axes in the defined position of grooves H and l3 or l2 and l4, which will never be parallel, and the rotation will be limited by the existence of the pair of axes 15 and 16, one in each for of grooves 11 and 13, or 12 and 14.
- the proposed chair 1 optionally also has a footrest 20 that is provided with the corresponding height adjustment means in order to be adaptable to any user.
- Another optional feature is to provide the chair 1 with a support tray or work surface arranged between the armrests, for example folding with respect to one of the sides, in which to place work or leisure means, such as computer accessories (keyboard, mouse , laptop, or a book or games).
- work or leisure means such as computer accessories (keyboard, mouse , laptop, or a book or games).
- said tray may be provided, with the corresponding fixing or accommodation means, with a flange for preventing the articles from falling.
- the seat is folded down by means of the movement of a lever arranged on one or of its sides, so that by means of the adequate reduction the pinions move relative to the zippers.
- the movement can be driven by an electric motor.
- the relative displacement between the racks can only be carried out by one of the axes 15 or 16.
- the second axis will be kept at the appropriate distance from 1 to 1 first, by less than 1 rod or separation rod.
