Description

250 1985

  Armchair adjustable and transformable.

  The invention relates to an adjustable and transformable armchair

  This is indicated by the variety of its adjustment possibilities and practical use.

  It is known to put the back of an armchair in

  inclined positions and to obtain various posi-

  the backrest and seat using additional

  A transverse bar can be freely arranged.

  The object of the present invention is to provide a

  which can be used on demand, be isolated-

  as a table seat for meals, or a garden chair when the backrest is in an inclined position, or as a comfortable resting chair

  or sleeping furniture by attaching an additional surface

  by coupling a second chair.

  This object is achieved according to the invention for a chair

  thanks to a seat whose side walls,

  their ends before and below the seat, are

  hingedly connected by a metal rod with the front ends of a primary frame, and thanks to a backrest whose lower ends, above the seat, are hinged to the seat near his

250 1985

  rear end and whose side walls have supports projecting downwardly and offset rearwardly, with at least one recess at the free end, for example, can be mounted between the U-shaped sides of the primary frame of fixed rods which may be surrounded by a recess at the lower end of the back support, and vertical grooves in the upper longitudinal sides of the side walls of the U-shaped frame, in which a rod

  free transverse can be accommodated at will for the

  the lower edge of the longitudinal sides of the seat.

  In this case, it is advantageous to ensure that at least one

  in addition to the point of ar-

  seat and backrest, to be able to better

  hold the spine of the user.

  It is further advised that on one side of the stems

  primary chassis, and between the seat and the

  side of the primary chassis, either without a pivot bracket

  freely fit into the free space

  the U-shaped frame and the seat of a second armchair turned from 1800, whose through stem is received in

  a recess formed at the free end of the tab.

  It is also possible to provide a seat extension with longitudinal longitudinal grooves at the front end, in which penetrate pins provided on the

  internal faces of the primary frame.

  Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figures 1 to 3 show the chair in various

  grinding according to the invention before assembly; Figure 17 shows the chair in the form of a usual chair: Figure 18 shows the chair in stool position, and Figure 19 shows two chairs used at the same time to form a convalescence bed The armrests 1 and feet 2, 3 respectively form

  together a U-shaped frame in which a wall la-

  4 is fixed mounted. The armrests 1 and the feet 2, 3 are furthermore rigidly connected to each other by a transverse board 5 and by bars 6 to

  9 fixed. A transverse bar 10 is further provided,

  in longitudinal grooves 11 which are milled, as well as recesses 12, -13 of semicircular shape,

  in the upper longitudinal side of the side walls 4.

  In addition, a fixed iron bar 14 is provided for

  also due to the rigidity of the fixed frame. The iron bar 14 passes beneath a seat 15 and, at its front end, passes through the side walls 16 of the seat 15 forming the fixed point of rotation of the seat. Above the seating surface and near its rear end is a hinge 17, one leg of which is

  rigidly connected to the side walls 18 of a backrest 19.

  The rear part of the side walls 18 of the file 19

  is extended downwards and forms a light support

  staggered backwards, in the lower end

  which is formed a recess 21 in the form of a semicircle.

  It will be shown in what follows what positions

  lets take the chair described.

  In FIG. 1, the backrest 18 has a slightly

  clenched backwards. This is the case when the fixed rod 6 is in the recess 21 of the support 20. The rear part of the seat 16 is, in this case, slightly raised

by articulation 17.

250 1985

  In FIG. 2, the support 20 projects freely between the fixed bars 6 and 7, and the lateral walls 16 of the seat rest by their lower longitudinal edges on the

  fixed bar 9. The backrest 19 is strongly inclined towards the

  Rière. The rear part of the seat 15 is pivoted downwards

around the iron bar 14.

  In FIG. 3, the fixed bar 8 is in the recess 21 of the support 20. At the articulation 17, the rear part of the

  seat 16 is slightly rotated upward.

  In FIG. 4, the fixed bar 9 is in the recess 21 of the bar 20. The rear part of the seat is strongly

  pivoted upwards from the hinge 17.

  In FIG. 5, the backrest 19 is rotated anti-clockwise around the hinge 17 to such an extent that the front edge of the support 20 rests against the rear face of the seat 15. The backrest and the seat form

a flat surface.

  In Figure 6, the backrest and the seat, in the extended position

  5, are rotated in the direction of the auto-clockwise of the metal bar 14. The free crossbar 10 no longer rests in the groove 11, but in the groove 12, so that the crossbar

  free rest against the rear edge of the support 20.

  In FIG. 7, the backrest 19 is pivoted clockwise around the hinge 17 until the free end of the backrest rests on the top of the seat 15. The free transverse bar 10 found again in the groove 11. The lower edges of the walls

  side 16 of the seat 15 rest on the fixed bar 9.

  It is then the folded position of the chair in the-

  which one can, for example, be slipped under a

a table.

  FIG. 8 shows the chair in the same folded position,

in front view.

  Figure 9 shows the case where two chairs according to the invention can be used as a bed. The chair shown

  on the left is in the position according to Figure 4. The

  right-hand gravity is in the position shown in the figure, but turned so that the two front ends of the armchairs face each other by the transverse planks 5. As shown in Figure 8, a free space is left between the U-shaped frame 1, 2, 3 and the side walls 16 of the seat 15, which space is filled on the right side of each chair by a tab which can rotate freely on the iron bar 14 and whose free end can be folded into the free space on the left side of the other chair. Since lateral recesses

  23 are at the free ends of the legs 22, these

  the legs, when folded down, hold the two tins 14 together at the end

before armchairs.

  If you want to lift your legs, you give the chair

  on the right, the position according to FIG.

  Another embodiment of an adjustable chair according to the invention comprises, in accordance with FIG. 10, a primary frame 31 with feet 32 inclined backwards at the ends of the casings, are reported rollers 33, two stiffening plates 34, 35, a iron bar 36, a wooden bar 37, an iron bar 38, guide rails 39 and tenons 40. A seat 41 is provided with strips 42 and holes

  43 who receive the ends of the iron bar 38.

  43, at the rear end of the seat, is

  provided a plate 44 with a hole 45.

  A folder 46 with bands 47 has a hole 48 and a round bar 49, and it is provided at the lower end

250 1985

  widening, a plate 50 which maintains an iron bar 51 and which has, in addition to a hole 52, recesses

53 to 55.

  The hole 48 of the backrest 46 receives a hexagon screw passing through a hole 56 formed in the rear end of an armrest

  57, while a leg 58 with hole 59 is connected to articula-

  by a hexagonal screw with the upper end of an armrest support 60 with hole 61, and carrying a bar 62

  maintained by the guide 39 of the primary frame.

  The tenons 40 of the primary frame penetrate into a groove

  longitudinal 63 of a seat extension 64 with bands 65.

  The adjustable chair shown in Figure 11 results from

  mounting the individual parts shown in Figure 10.

  If the backrest 46 is lifted slightly and rotated clockwise forwards

  the horizontal position, we then obtain the position of non

  use of the chair according to Figure 12.

  If, on the contrary, the file 46 is rotated

  clockwise in such a way that it forms the extension of the seat 41, the chair can then be brought into the erected position represented in FIG.

  which takes up little space for storage.

  If the backrest 46 is left in the extended position according to FIG. 13 and if the seat extension 64 is further folded around the tenons 40, in the direction of clockwise forwards, the lower face the seat extension 64 then rests against the wooden bar 37 and the totally horizontal coating is obtained in accordance with the

figure 14.

  FIG. 15 shows the position of the chair according to the invention in the form of a convalescent seat, the backrest 46 being raised and pivoted in such a way that the iron bar 36 is housed in the recess 53 at the lower end of the seat. folder. The seat extension 64 is further raised at the free end and moved slightly inwardly so that the iron bar 38 is supported by

  stepped front end of seat extension 64.

  According to a third embodiment, the recliner

  Figure 16 includes a primary frame 71 with rearwardly inclined feet 72, and slightly more straightforward front feet 73, fixed reinforcement strips 74.

  and 75, a fixed iron bar 76 and a wooden bar 77

  xe. In addition, there is also provided an iron bar 78 as well as inside the primary frame and at its end

  before, a guide rail 79 on each side as a

lower section of a recess 80.

  A seat 81 comprises strips 82, holes 83 and 84, and a pin 85. The hole 83 serves to receive the iron bar 78. The holes 84 receive a hexagonal screw around which can rotate freely a support lever 86 with transverse bar 87. The iron bar 76 can be housed

  in a recess 88 of the free end of the control lever

  86. The tenons 85 fit in holes 89 of a

  iron plate 90 at the lower end of the part la-

  of a folder 91 bearing a bar 92 and recesses

  93, 94 in which can be arranged to choose the bar 76. The folder 91 has strips 95 and holes 96 in which fit hex nuts associated with the holes 97 of the armrests 98. Below the armrests 98 are provided fasteners 99 with holes 100 in which hexagonal screws passing through a hole 101 in an armrest support 102 are fitted. At the lower end of each support 102 there is provided a stud 103 projecting

  laterally which is held by the rail guide 79.

  A hole 104 in the primary frame 71 and a hole 105 in a wooden hook 106 at recess 107 serve for

receiving hexagonal screws.

  Figure 17 shows the spare parts of Figure 16 in

  the mounted position of the chair. After the uprising of the back

  by the upper end and after its elevation, the iron bar 76 is housed in the recess 94 of the file

  91, and the latter has a slight inclination towards the rear.

  By the armrest 98, the upper part of the support bar 102

  has been dragged backwards, and the tenons 103 at the

  lower half rest against the right end of the guide

  79. The support lever 86 retains the position out of use.

  If the file 91 is placed even more vertical, the lower end of the file is then left in front of

  .5 the iron bar 76, and this is against the edge

  bottom of the side walls of the seat 81.

  If the back is tilted further back, the

  Iron bar 76 then comes into recess 93.

  In the substantially horizontal position of the folder

  shown in Figure 18, its lower end is supported on the one hand against the underside of the strips 82 of the seat 81 and on the other hand against the iron bar 76. The wooden hooks 106, which are in the same plane as the side walls of the backrest 91 on the outer sides of the seat, are

  covered, in the position shown, by the walls la-

  side of the seat. As can be seen in FIG. 18, the armrests 98, in the horizontal position of the backrest 91, almost do not protrude upwards and clenches two persons who sit on the seat in the seat.

  stool position shown in Figure 18.

  Figure 19 shows again the seat according to the invention in the position of Figure 17. A second chair according to

  the invention is however additionally placed

  in such a way that the front ends of the two

  sires almost touch each other. The wooden hooks 106 of the left seat are also folded to the right and the bar

  in wood 77 of the right armchair is housed in the recess-

  107 of the wooden hook 106, the right chair being connected to the chair left safely but still removable. In the right chair, the support levers 86 are further pivoted downward about their point of rotation

  84 so that the iron bar 76 of the right armchair

  it can be accommodated in the recess 88 of the support lever 86. The seat 81 thus takes an inclined position upwards and the backrest 91 also takes this inclined position in the

  extended configuration according to Figure 18.

  Two chairs in stool configuration can naturally

  also be linked to one another by the drawdown

  hooks 106. They thus form a four-seater bench.

  It is also possible to fold the backrest 91 tilted back of the left chair shown in Figure 19 to the horizontal position shown in Figure 18, so that it forms an extension for the legs,

  the backrest is strongly inclined downwards and the seat

  steeply inclined right armchair used to

the support of the body.

  If the seat is rotated in the stool position according to FIG. 18, clockwise around the front legs 73, the front end of the seat is supported by

  on the floor and thus one obtains the folded position allowing

  both the storage of the seat when not in use.
