Title: Reclinable folding deckchair

Description:
TECHNICAL FIELD 
     The present disclosure concerns the field of furniture and more specifically that of foldable and reclining armchairs or chairs comprising at least a backrest and a leg-rest. 
     BACKGROUND 
     An example of these armchairs is described in French patent FR2721811. This document describes a relax armchair comprising: a frame forming the backrest; two parallel beams forming the seat, the beams being hinged in the vicinity of the lower end of the backrest frame; two armrests parallel to each other and parallel to the beams of the seat, the armrests being hinged on the backrest frame, each armrest having a sliding axis parallel to the beams; a U-shaped frame forming the leg-rest whose two branches are hinged to the end of the beams, the upper end of the branches of the leg-rest frame is hinged at the end of the armrests; a stretched piece of fabric being hooked on the frame and to the beams by elastic means. 
     The armchair according to this document further comprises a stand formed by two jambs, a front jamb and a rear jamb respectively, each jamb being formed by parallel legs secured to the beams, said jambs being hinged together around a yoke, the end of each front jamb having a yoke adapted to slide on said sliding axis and a means for blocking position of the armchair, the legs of the jambs being connected together by a hinged connecting rod, respectively on the front jamb and on a yoke fastened on the rear end of the beam, adapted to enable the sliding of each rear jamb. 
     Thus, the transmission of movement between the backrest and the leg-rest is achieved by the deformation of the quadrilateral formed by the backrest, the leg-rest, the seat beams and the sliding axis of the armrest. During this movement, the entire stand is stationary, in particular the sliding yoke and the yoke located at the rear of the beam, so that the armrest is displaced at the same time as the backrest. 
     As described in this example, the yoke at the rear of the beam is secured to the seat beam and enables the sliding of the jamb relative to said beam. The drawback of this configuration is that this yoke is not totally satisfactory from an aesthetic point of view, in particular since the screw maintaining the yoke fastened is apparent and makes the overall appearance of the armchair less attractive.

     According to the disclosure, the receiving shell  1   b  further comprises a second receiving housing  3   b  shaped so as to slidably receive a rear leg  105   b  of the jamb  105 , as represented in  FIGS. 5 to 10 . Advantageously, the covering shell  1   a  comprises a complementary second receiving housing  3   a  shaped so as to at least partially receive the rear leg  105   b  housed in the second receiving housing  3   b  of the receiving shell  1   b . Thus, when the jamb yoke is closed, as represented in  FIG. 10 , the rear leg  105   b  is enclosed within the jamb yoke  1 . 
     Advantageously, the covering shell  1   a  comprises a closure member  7  of the jamb yoke  1 , said closure member  7  being configured to cooperate with a complementary closure member  8  formed in the receiving shell  1   b , as illustrated in particular in  FIGS. 8 and 10 . 
     The closure member  7  is projecting with respect to the covering shell  1   a  and more particularly extends according to an axis secant, and preferably substantially perpendicular, to the longitudinal axis according to which the jamb yoke  1  extends, as shown in  FIG. 10 . The closure member  7  has at a free end a retainer element shaped so as to cooperate with the complementary closure member  8 , and more specifically with an orifice  8   a  formed in the complementary closure member  8 . 
     The complementary closure member  8  is formed above the second housing  3   b  of the receiving shell  1   b  as shown in  FIGS. 8 and 10 . The complementary closure member  8  comprises an orifice  8   a  shaped so as to cooperate with the closure member  7  of the covering shell  1   a.    
     As illustrated in  FIG. 6 , the covering shell  1   a  further comprises two guide blades  12  arranged on either side of the complementary first receiving housing  2   a . The two guide blades  12  being intended to cooperate with a indentation formed in the receiving shell  1   b . Of course, these guide blades are optional and may be more or less than two in number. 
     Furthermore, in the example illustrated in particular in  FIG. 7 , the covering shell  1   a  comprises a retainer element  11  shaped so as to cooperate with a complementary retainer element  10  formed on the receiving shell  1   b . The retainer element  11  comprises a free end preferably having a hook-like shape as shown in  FIG. 7 . 
     The receiving shell  1   b  comprises a complementary retainer element  10  shaped so as to cooperate with a retainer element  11  formed on the covering shell  1   a . The complementary retainer element  10  comprises a projecting portion, the shape of the free end of the retainer element  11  is shaped so as to be engaged on said projecting portion of the complementary retainer element  10 , as illustrated in  FIG. 10 . 
     As shown in all of  FIGS. 5 to 10 , the covering shell  1   a  has a face constituted by the cover and an opposite face comprising all the components described hereinabove and each intended to cooperate with a complementary component of the receiving shell  1   b.    
     Moreover, on each jamb  105 , the armchair  100  comprises means for limiting the sliding of the rear leg  105   b  made using a connecting rod  106  and an element  107  forming a stop. 
     The connecting rod  106  has a first end  106   a  hinged around the front leg  105   a  and a second end  106   b  hinged around the jamb yoke  1 . More specifically, the first end  106   a  is bent around a fastening element passing through the front leg  105   a , as represented in particular in  FIG. 12 , and the second end  106   b  is bent around the fastening member  4  so as to be housed in the jamb yoke  1 , as represented in  FIG. 7 . 
     The element  107  forming a stop is fastened in the rear leg  105   b  using a fastening rod  109  passing through orifices  110  carried by said rear leg  105   b.    
     During the deployment of the armchair  100 , each rear leg  105   b  will slide backwards until the element  107  abuts against an area of the connecting rod  106  located in the vicinity of its second end  106   a . The armchair  100  is then stabilized and enables the seating of a person. 
     The receiving shell  1   b  advantageously has a concave receiving area  108  shaped so as to receive the element  107  when it comes into contact with the connecting rod  106 . Thus, this allows avoiding the concentration of the forces exerted by the element  107  on the sole connecting rod  106  and distributing them between the jamb yoke  1  and said connecting rod  106 , safety and stability being thereby increased. 
     Of course, the disclosure is not limited to the embodiment described and represented in the appended figures. Modifications are still possible, in particular with regards to the constitution of the various elements or by substitution of technical equivalents, yet without departing from the scope of the disclosure.
