Abstract
Description
- The present invention concerns a mechanism for a so-called relaxation chair, in other words a chair which, as is known, is provided with a seat, a back and a footrest and which can be put from a sitting position into a reclined position.
- In particular, the present invention concerns a mechanism for such a relaxation chair which can be put in the different positions in a continuous manner.
- In known mechanisms for such relaxation chairs, the seat is set in a fixed angle in relation to the supporting structure and the back and footrest are hinge-mounted to this seat, whereby a bar transmission forms an irregular parallel connection between the back and the footrest.
- These known mechanisms are disadvantageous in that in no way is obtained a good reclined position since, when moving from the sitting position into the reclined position, one is easily inclined to shift towards the front of the seat and/or whereby there is a relative displacement between the body and the back of the chair.
- In the known mechanisms of this type, various parts of the mechanism are visible, either in the sitting position, in the reclined position or in both positions.
- This is usually not only unaesthetic, but it is often also dangerous because of the shear effects of the bars of such mechanism.
- Moreover, the known mechanisms are often difficult to operate.
In these known mechanisms, the lever transmissions are selected such that they make it possible for an average person to tilt the chair in the required positions. - However, this is disadvantageous in that problems arise when such a chair is used by smaller or lighter persons, since the centre of gravity of said person is situated in another point of application of the chair.
- It has also been found that in the known mechanisms, the length of the footrest is relatively short, since this length is limited by the distance between the seat to which it is linked and the floor upon which the chair is placed, one and other such that it is almost impossible for a normal person to let the feet rest on such a footrest.
- Also, the present invention aims a relaxation chair which systematically excludes the above-mentioned and other disadvantages of the known chairs.
- To this aim, a mechanism for a relaxation chair according to the invention mainly consists of the combination of a seat which is provided on a support in a freely swinging manner via which the whole is fixed on a foot; hinge-mounted to this seat, on the one hand a back and on the other hand a footrest; bent bars which form a connection between the back and the footrest; transmission levers between the back and the above-mentioned support; compensating springs between the seat and the footrest; and flexible means provided between the seat and the footrest.
- According to a special characteristic of the invention, the footrest of the above-mentioned mechanism is extensible, to which end the footrest is formed of two parts which can be telescopically moved in relation to one another and whereby springs are provided between these parts which continuously try to move them apart.
- According to another special characteristic of the invention, the extension of the footrest will be limited first by the upholstery of the chair and/or by a foil of elastic material fixed to the mechanism.
- Another special characteristic of the invention is the fact that the lever transmissions between the back and the support on which the seat is fixed in a swinging manner are determined such in combination with compensating springs provided between the seat and the footrest that the seat mechanism is almost always in balance in any position whatsoever.
- In order to better explain the characteristics of the invention, the following preferred embodiment of a mechanism for a relaxation chair is described as an example only without being limitative in any way with reference to the accompanying drawings, in which:
- figure 1 shows a schematic side view of a relaxation chair according to the invention, whereby the chair is in the sitting position;
- figures 2 and 3 are views similar to that in figure 1, but whereby the seat is in an intermediate position, a reclined position respectively;
- figure 4 shows a view in perspective of the mechanism in the position as represented in figure 1;
- figure 5 shows a view in perspective of the mechanism in the position as represented in figure 3;
- figure 6 shows a partial section according to line VI-VI in figure 4;
- figure 7 shows a partial section according to line VII-VII in figure 5;
- figure 8 shows a view of the part indicated by F8 in figure 4;
- figure 9 shows a section according to line IX-IX in figure 8;
- figure 10 shows a view of the part indicated by F10 in figure 5.
- As shown in figure 1, the
mechanism 1 according to the invention mainly consists of aseat 2 which is fixed to asupport 4 in a freely hinging manner which is fixed in turn to anactual foot support 5 which is for example designed such that such a chair can turn aroundpivot 6 of thisfoot support 5. - To the rear end of the
seat 2 is fixed, via apivot 7, in a freely hinging manner, theback 8, whereas to the front end of theseat 2, via apivot 9, in a freely hinging manner, is fixed thefootrest 10. - The
back support 8 is provided, at the height of itshinge point 7, with a forwardly directedprotrusion 11 which so to say forms a lever and which, at its free end, is connected in a freely hinging manner, via apivot 12, to thelever 13 which is connected in a freely hinging manner at its other end, via apivot 14, to thesupport 4. - The
back 8 is connected in a freely hinging manner tot thefootrest 10 by means ofbent bars 15 and pivots 16-17. - Finally, the
footrest 10 consists of afirst part 18 which is connected by means ofdraw springs 19 to theseat 2 and of asecond part 20 which can be moved in a restricted manner in relation to thepart 18, whereby this movement is controlled bysprings 21 on the one hand, provided between theparts upholstery 22 of the chair on the other hand. - With the exception of the
parts - When a person is seated in the chair in the position as represented in figure 1, the chair mechanism will be in balance thanks to the cooperation of the levers formed between the hinge points 12-13, 12-14 and 14-3 on the one hand, and the tensile force exerted by the
draw springs 19 on the other hand. - The
upholstery 22 makes sure, in this position, that thepart 20 of thefootrest 10, against the action of thesprings 21, is maintained in the slid-in position. - When the chair is put into the reclined position, whereby normally the chair will remain in balance in all intermediate positions thanks to the compensatory action exerted by the
springs 19, anexcess part 23 ofupholstery 22 will be formed as theparts springs 21 to telescope out thepart 20 of thefootrest 10 in relation to thepart 18, which has a result that not only theupholstery 22 is maintained entirely stretched, but also that anextended footrest 10 is obtained. - By using
bent bars 15, the total height of the seat will moreover be restricted, so that there is more space to provide comfort-increasing soft foam. - A preferred embodiment of a chair mechanism according to figures 1 to 3 is described in figures 4 to 10.
- One will notice hereby chat the
seat 2 is formed as it were of two sides 24-25 which show outwardly directed parts 26-27 at the top which form the supports onto which the actual armrests can be fixed. - The sides 24-25 are connected to one another by means of a solid,
bent tube 28. - Hingeable in 3 is provided a
bent cross-plate 29 with the sides 24-25 which has acentral attachment 30 with which this plate is connected to the above-mentionedfoot 5, preferably in a rotatable manner. - The
seat 8 is in this case formed of a U-shaped,tubular frame 31 in between which can be provided springy means which are not represented, whereby thisframe 31 is connected in a removable manner at the bottom to a transversally directedplate 32 which has bent parts at its ends which form the above-mentionedprotrusions 11 with which thelevers 13 are fixed viapivots 12 itself. - In this embodiment, at least one of the
bent bars 15 shows a downwardly directed widening 33 in which is provided abent groove 34, whereby abar 35 passes through this groove which is screwed in aplate 36 which is fixed, for example by means of welding, to theside bar 35 is provided with suitable press-on means which, when turned, draw thebar 15 against theplate 36, loosen it respectively, in order to lock the mechanism in a certain position, free it respectively, by changing the friction between theplate 36 and thebar 15. - The
parts footrest 10 are formed in this case of a square tube, save for theside parts 37 of thepart 20 which are made as a U-profile, one and other such that guides 38-39 which are provided on the sides of thepart 18 can be shifted in theseside parts 37. - The
springs 21 are provided aroundbars 40 which are fixed on thepart 20, whereby these bars are provided withstops 41 at their free end which have as an aim to determine the maximum movement of thepart 20 in relation to thepart 18. - Finally, the
springs 19 are connected to thetube 28 of theseat 2 in this embodiment. - Preferably, a foil (42) made of elastic synthetic material will also be provided onto such a mechanism, which can follow all the movements of the mechanism and which determines the final shape of the chair. This foil will be fixed to the
back 8 on the one hand and to thetelescopic part 20 of thefootrest 10 on the other hand. - It is clear that a mechanism is obtained in this way which remains in balance in almost any position for almost any person, thanks to the appropriate selection of the length of the levers 11-13 in combination with compensating
springs 19; which can be appropriately fixed, if required, in any position whatsoever; and whereby is used a footrest which is extended in the reclined position of the chair. - It is clear that the invention is by no means limited to the embodiment given as an example and represented in the accompanying drawings; on the contrary, such a mechanism according to the invention can be made in all sorts of shapes, dimensions and materials while still remaining within the scope of the invention.
