Description
Background of the Invention
1. Field of the Invention
The present invention relates to easy chairs and more particularly to those used out of doors.
2. History of the Art
A considerable number of easy chairs, reclining chairs and the like intended for relaxing out of doors exist on the market. Certain of these devices are of the "wheelbarrow" type, i.e. they comprise a frame of which one of the ends is associated with a pair of wheels. In this type of article, the backrest is sometimes inclinable in several positions, while the leg rest is made in one piece with the article or is independent thereof. In certain other cases, easy chairs of the type in question exist, of which the leg rest is articulated with respect to the seat surface.
In all cases, it is necessary for the user to rise from the chair if he wishes to change the inclination of the backrest and/or of the leg rest, which is a drawback. In addition, the so-called "wheelbarrow"-type easy chairs cannot be stacked due to the presence of the wheels.
Object of the Invention
It is an object of the improvements forming the subject matter of the present invention to overcome the drawbacks of the known easy chairs and to produce such a chair which responds better than heretofore to the various desiderata of the users.
The invention will be more readily understood on reading the following description with reference to the accompanying drawings, in which:

FIG. 2 is a side view of the easy chair in the position wherein all its elements are extended.
FIG. 3 is a view in detail, on a larger scale, showing in section the manner in which the end of each armrest is in abutment on a part of the frame in the retracted position of said armrests.
FIG. 4 illustrates how the end panel of the leg rest abuts on the frame in the position illustrated in FIG. 2 of the chair according to the invention.
FIGS. 5 and 6 illustrate the chair according to the invention in two positions of use.
FIGS. 7 and 8 are views similar to that of FIG. 3, but showing how the end of each armrest cooperates with the frame in the positions of the chair illustrated in FIGS. 5 and 6, respectively.
FIG. 9 is a view similar to that of FIG. 4, but corresponding to the position of the chair illustrated in FIG. 6.
Description of the Preferred Embodiment
Referring now to the drawings, the easy chair according to the invention essentially comprises a frame 1 illustrated in FIG. 1. This latter comprises two longitudinal elements 2, 3 joined by crosspieces 4, 5, 6 and 7. It is observed that crosspiece 4 joins one of the ends of the two longitudinal elements 2 and 3, whereas crosspiece 6 lies at about two thirds of the length thereof. As for crosspiece 7, it joins, as illustrated, the ends of the longitudinal elements opposite those which are joined by crosspiece 4.
It will be noted that, opposite crosspieces 4 and 6, the outer face of the longitudinal elements 2 and 3 have legs 8, 9 respectively, depending therefrom which have a horizontal transverse section in the form of a U of which the central vertical web 8a, 9a is placed near each longitudinal element, while flanges 8b, 9b are directed outwardly. The flanges of each leg are slightly convergent towards the ground and are joined by a foot 10 adapted to rest on the ground.
In other words, the legs are generally in the form of an upwardly open V.
One of the flanges 9b of the legs 9 which lies to the rear comprises an inclined partition 9c for reasons which will be better explained hereinbelow. Above the crosspiece 5 which lies roughly in the middle of longitudinal elements 2 and 3, but whose position may vary, a seat surface 11 has been placed, constituted by a narrow transverse lath which is fixedly associated on top of the longitudinal elements 2 and 3. On either side of the two ends of the seat surface 11, there are provided two horizontal pivots 12, 13 and 14, 15. Pivots 12 and 14 are in alignment with each other so as to constitute with a corresponding part a hinge for a leg rest 16 (FIG. 2). Likewise, pivots 13 and 15 serve for the articulation of a backrest 17 with respect to the seat surface 11.
On each of the lateral sides of the backrest 17 there is hinged an armrest 18 whose free end rests against a horizontal extension 9d of the oblique partition 9c of the corresponding leg, as illustrated in FIG. 3. Of course, when the backrest is folded down against the frame, it is maintained in horizontal position by crosspiece 4.
The leg rest 16 which, for its part, is articulated about pivots 12 and 14, is constituted by two panels 16a, 16b of which the former comprises at the level of one of its ends means for pivoting about pivots 12-14. The other end of panel 16a is pivotally associated with the end panel 16b. The latter comprises on its outer face transverse reinforcing ribs referenced 16c. Two of these ribs are extended downwardly so that, in horizontal position of the leg rest, one of these ribs referenced 16d abuts against two blocks 7a made at each end of the crosspiece 7, as illustrated in FIG. 1. The vertical lateral faces of panel 16b each comprise a cant or catch 16e which, in the position of FIG. 4, rests against the oblique face of the corresponding block 7a.
When a user is stretched out in dorsal decubitus on the easy chair of which the elements are horizontal, his buttocks rest on the seat surface 11. If the user sits up, he may grip the arm rests and move them forwardly with a view to tipping the backrest upwardly, for example as illustrated in FIGS. 5 and 6. In the first of these positions, he may bring a finger or extension 18a of the armrest into one or the other of two perforations in the form of slots 19, 20 made transversely in the partition 9c of the corresponding leg 9. Each finger comprises a groove 18b in which is elastically positioned the upper rounded edge 19a, 20a of each perforation 19, 20. It is observed that, to this end, the finger comprises a certain thickness so that it cooperates with the two edges of each slot, with the result that the armrest is thus wedged in one or the other of its two positions which determine those of the backrest 17 (FIGS. 7 and 8).
As illustrated in FIG. 6, when the user is sitting on the seat surface 11 and his back rests, or not, against the backrest, he can raise the leg rest so that its two panels 16a, 16b determine therebetween an obtuse angle in order to support the user's legs when they are slightly bent. The fact of bringing the leg rest to this position provokes a displacement of the cants 16e with respect to blocks 7a of crosspiece 7, so that a stop 16f comes into abutment against blocks 7a. There again, the lateral faces of the end panel 16b of the leg rest 16 comprise cants 16g which cooperate with the oblique faces of the blocks 7a (FIG. 9). It is observed that stop 16f is also a transverse rib whose height is greater than that of rib 16d described previously.
It will be readily understood that the change of position of the leg rest is effected without the user having to get off the easy chair and that this change of position is made without effort due to the cooperation of the cants 16e with respect to the oblique faces of blocks 7a.
As illustrated in FIG. 2, easy chairs according to the invention may be stacked on one another with their hinged elements folded in abutment against the frame since the legs 8 and 9 are offset outwardly, they have an upwardly diverging form and are laterally and outwardly open. The legs of the chairs engage in one another in order to obtain a stack of chairs.
Legs 8 of the chairs may also be associated with dismountable wheels 21 illustrated in discontinous lines in FIG. 2.
It must, moreover, be understood that the foregoing description has been given only by way of example and that it in no way limits the domain of the invention which would not be exceeded by replacing the details of execution described by any other equivalents.
