Definitions

  • Our invention relates to a reclining phair, and more particularly to a foldable reclining ch ii, in which a leg-rest, a seat, a back-rest and connecting link-means are pivotally. interconnected with each other to form ,a polygonal structure withunequal sides andwherein said polygonal structure is movably connected to said support.
  • One object of our invention is ;to provide a foldable reclining chair of the above described. type, inwhich the members of the polygonal structure may be folded upon each other iintwo parallel planes.
  • Another object of our invention is. to provide a 'foldable reclining chair of ,theabove described type, in which the members of the polygonal structure may befoldedupon each other in two parallel planes, and in which, the members of a foldablesupport are positioned in one of said planes, when the chair isfolded.
  • a furtherob'ject of our invention is to provide such a foldable reclining chair withanovel looking device for locking the movable parts of the polygonal-structure in anydesired position, so that the user of the chair may gradually shift the movable parts of the polygonal structure from any adjusted position into any other more reclined position by gradually loosening said looking device and pressing back against said back-rest, while he rests-on the chair.
  • a foldable recliningch'air comprising a support, and'a polygonal structure
  • invention-theconnecting link-means form thearm-rests on each side of the chair and are provided with slo;ts';'one point of the polygonal struotureisv pivoted to the support; pins are secured to the support on each side of the chair and are in movable engagement with said slots for controlling the movement of the members of thepolygonal structure, when the latter, is swungaboutits pivot point onjthe support; the pivot points between the back rest and the arm-rests are.
  • Fig.1 is a side elevational viewfof the foldable reclining'chair .in sittinglposition
  • 'i 'Fig. 2 is a perspective view of the foldable reclining chair shown in Fig. 1,
  • Fig. 3 is a fragmentary top plan view of an arm-rest of thechair, illustrating thelockin-g device in an enlarged scale
  • I Figs. ,5ar-5c are side elevational views of the chair illustrating subsequent positions of the parts of the chair, when the folding of the chair isstarted from a reclining position.
  • the support of the chair consists of two pairs of uprights l and 2, one pair being arranged on eachside of the chair.
  • the upright 2 is hinged to the uprights Iat 3.
  • a plate 35 of curved shape is secured to the upper end of each upright i and carries a pin orpivot 36 for a purpose to be describediater on; r
  • N indicates the leg rest, which is provided With 'a'st'r'ip M of fabric or the like attached thereto.
  • 7 indicates the seat having a plurality of .strips iii of fabric or the like secured thereto.
  • ⁇ t indicates the back-rest; whichis provided with 1 l a plurality of stri'psS'l ,of fabric or the lil ze' attached' thereto. 8 indicates" connectingylinks,
  • each arm-rest 8 is hinged [to theupperendof the legerest H at The 'backerest 4 provided with pivots IElfon feach side of the chair. Said pivots are positioned' at intermediate points of the back-rest and are in slidable engagement with said slots 9 of the arm-rests, so that the distance between the pivots l2 and I9 may be changed, if desired.
  • the leg-rest H, the seat I, the back-rest 4 and the arm-rests 8 form a polygonal structure having sides of unequal length, the shortest side being the upper part of the leg-rest H between the pivots l2 and 38.
  • the back-rest 4 has an extension 39 on each side of the chair, and said extension is pivoted to the upright! at 5, so that the polygonal structure may be rotated about said pivot 5, if it is desired to bring the movable parts thereof from the sitting position shown in full lines in Fig. 1 into a reclining position shown in dash and dotted lines in Fig. 1.
  • the movements of the members of the polygonal structure during said adjustment are controlled by the pins 36, which are in slidable engagement with the guiding slots 9 of the arm-rests 8.
  • the pins 36 In order to lock the movable parts of the polygonal structure in any adjusted position, the pins 36 have a threaded end extending outwardly from the arm-rest, and a clamping knob 10 or the like'is screwed on this end for pressing a clamping'diso 40 loosely arranged on said pin 35 against the surface of the arm-rest. If the disc 40 is pressed against the arm-rest, the polygonal structure is locked.
  • the side of the armrest 8 facing the clamping disc 48 has an inc-lined surface l6, which permits a gradual change'from' the sitting position or an intermediate reclining position into a more reclined position'of the polygonal structure while the user of the chair rests thereon. Assume, the parts of the chair are locked in an intermediate reclining position, when the clamping disc is tightly pressed against the recess 15 in the position shown in Fig. 3.
  • the shoulder l1 formed by the inclined surface 16 limits the sitting position of the polygonal structure, when the clamping disc at abuts against said shoulder.
  • the extreme rec-lining position of the polygonal structure is limited by an engagement of the pin 36 with the front end 4
  • Transverse bars 20, I5, 50 and [8 are secured to the side bars of the leg-rest II, seat 15 and back-rest 4 respectively, and connect the two polygons on each side of the chair with each.
  • the chair is in sitting position.
  • the upright I is in the same plane as theleg-rest H and the seat 1, and the upright 2 may be swung about its pivot 3 so that it comes into the same plane as the upright l and the entire width a of the folded chair is equal to the sum of the width b and c of two members of the chair only.
  • Figs. 5a-5c illustrate the folding of the chair, when its parts are in a reclined position.
  • a foldable reclining chair comprising: a pair of uprights on each side of the chair, the uprights of each pair being pivotally connected with each other; a pivot secured to the upper end of one of said uprights on each side of the chairf two polygons one at each side.
