Description

The invention relates to a lounge chair of the kind where the adjustment of

  the inclination of the backrest produces a corresponding and automatic adjustment of the inclination of an element

  before intended to support the feet of the user.

  Sun loungers of the type in question and known

  in the prior art have structural features

  ture and complicated operation, which lead to high-priced products with operating constraints, or others of simpler characteristics, but insufficient in terms of comfort, when considered from a point of view general. Another negative aspect of the already known embodiments relates to the weight

  excessive structures, and in addition to the difficulties of

  assembly of the assembly, which causes difficulties for the

  long distance transport, as well as for a sirpleremanie-

  furniture in a certain environment.

  Another disadvantage of the known lounge chairs

  day refers to the little variation in dimensions of the length

footrest age.

  As the footrest is placed substantially vertically-

  when it is in the out-of-service position, i.e.

  when the backrest is in the high position, and as the

  feet is articulated by its upper part to the front part of the chaise-longue seat, it happens that, regardless of the setting chosen for the headrest, such chair lo.ngue depending on the size of the user, the rest -feet will always have a fixed elongation corresponding substantially to the height (conventional) of the front part of the seat. The fixity of dimension of the footrests of known deckchairs has the effect that, in many cases, the users

  taller ones will have an extreme part of the legs

  ble which exceeds the edge of the footrest, which then becomes a poorly or unusable element, which can even be in

some harmful cases.

  It is an objective of the present invention to propose

  a chaise longue of simple construction, inexpensive and re-

  laterally light, fitted with an adjustable headrest and a

  front feet whose inclination is controlled by the inclination

  chosen seat of the backrest, the arms being automatically adjustable

  only in conjunction with the backrest and the footrest, thus conferring maximum comfort in all positions. Another object of the invention is to provide a footrest which allows an automatic increase in

  its longitudinal elongation, from a significant dimension-

  equal to the front height of the seat, up to a dimension capable of supporting them. feet of any user who is

  sitting in the lounge chair while raising the

  feet from its substantially vertical out-of-service position

  to a substantially horizontal service position. In-

  Another objective of the invention is to propose a chaise-longue of the kind defined above, comprising a headrest adjustable vertically by the user, when seated in the chaise-longue. An additional objective of

  the invention is to provide a chaise-longue as defined

  above, which has an easily removable structure for

  packaging and transport, which may be provided with a padding

  basic rabies covered with additional padding,

  removable and reversible, extended on the headrest, the backrest,

  arms, seat and footrest.

  Yet another objective of the invention is to provide a chaise-longue corresponding to the preceding aims and capable of an inclination adjustment controlled by any system which allows continuous adjustment and maneuvering from a

  point of the structure accessible to one of the user's hands

  sator sitting in the chaise-longue. These goals, and more

  very, of the present invention are obtained by a chair-

  long of the type comprising a seat fixed to a base support, a reclining back articulated on the seat, a footrest

  forward which can be tilted according to a tilt function

  set back, and a pair of side arms lift

vés in connection with the seat.

  According to the basic characteristics of the invention, the two lateral arms are each formed in a longitudinal beam having an elongation substantially equal to that of the seat, having their front end articulated on the front part of the seat by means of a rod. link, and their rear end articulated directly on the backrest and at a high point in relation to the axis of the backrest-seat joint, so that, in the maximum elevation position of the seat,

  the arms remain substantially parallel to the seat, and

  clinch forward as the seat swivels to its minimum elevation position; the seat comprising a front support on which is articulated the rear end of a small intermediate lever at the end of which is articulated the rear end of a small rigid rod having its front end articulated on the footrest; the middle part of said intermediate lever is articulated on the front end of a long, rigid rod, having its rear end articulated on an extension of the backrest structure, which extends downward from the point of articulation of this last at

seat.

  With the basic construction arrangement defined above

  above, when the user, after having unlocked the file, pushes or releases it, thereby modifying

  its angular position, the arms also modify their po-

  angular position in relation to the seat plane, adapting to

  the new attitude of the user on the seat.

  According to another provision of the invention, the change

  automatic angle of the footrest, depending on the in-

  cliniation imparted to the file, is obtained by the intermediary

  re of an extremely simple mechanism, comprising only

  two rigid rods and a small lever articulated on the seat.

  According to a construction variant of the invention, a support plate is mounted on the front face of the footrest structure, by means of a pair of arms in

  articulated parallelogram, parallel to the plane of said structure

  ture and movable under the action of these arms articulated on the

  plate and structure, between a retracted position and inac-

  tive covering said structure, when the latter is

  in its inactive vertical position, and a partial position-

  slightly offset towards the outside of said support structure

  feet, along the longitudinal geometric axis of the chair-

  long, said support plate maintaining the same minimum spacing relative to the footrest structure on its movement between said limit positions; one of the arms of the

  articulated parallelogram extending beyond its point of ar

  ticulation with the footrest structure to receive, in an articulated manner, the end of a rigid rod having its opposite end articulated on a predetermined point (if it is desired adjustable) of the seat structure, arranged in a

  arrangement lowered and retracted with respect to the axis of arti-

  culation of the footrest structure on the front part of the seat structure. With this arrangement, when the footrest structure moves angularly towards the

  high, around its axis of articulation, the point of articulation

  tion between the rigid rod and the elongated parallelogram arm tends to move away from the rear articulated point of the rod which, being rigid, causes angular displacement

  of said parallelogram arm around its point of articulation

  tion on the footrest structure, pushing the plate

  support forward gradually, said point of articulation

  tion acting to maintain the longitudinal axis of the plate

  support, parallel to the longitudinal axis of the seat. According to the-

  vention still, the headrest has a structure comprising at least two lower rods passing through guides fixed to the upper part of the backrest; one of the rods having its lower part hinged on a lever having its end pivotally mounted on the lower part of the backrest and the other end extending through a vertical guide, slightly outside one of the sides of the structure of

  backrest, over a sufficient length to allow its movement

  lying in the vertical direction by the user himself,

  while lying on the seat. Restraint of support-

  head in a given, chosen position is preferably ob-

  held by one of the rod guides, by friction action

between it and the guided rod.

  The invention will be described below with reference to the

  attached sins, in which: Figure 1 is a side view of the chaise-longue without any padding and in the maximum elevation position of the backrest;

appropriate ages.

  As shown in the drawings above, the chair-

  long object of the invention comprises a seat 10 fixed on a

  basic support set 20, reclining backrest 30, rear

  ticulated on the rear part of the seat 10, a pair of arms articulated directly on the backrest and indirectly, via rigid rods, at the front part of the seat, a front footrest 50 having its upper part articulated on the front part of the seat 10, and a headrest 60 mounted

on the record.

  The seat 10 comprises a flat rectangular frame supporting

  both, internally and through spring elements 11, a sheet 12 of a resistant material such as canvas. The seat 10 includes, in its front region, a support

  13, rigid, lower U-shaped having the ends

  of its lateral branches welded, or otherwise

  attached to the side rails of the seat frame.

  The base support assembly comprises: a front leg 21 formed of an upper column detachably attached to the support 13 of the seat, and forming a body an elongated lower plate disposed transversely to the longitudinal axis of the chaise-longue, acting foot support on the ground; and a rear leg 22, consisting of a flat U-shaped frame, having the upper ends of its branches fixed to the lateral extreme rear parts of the seat 10. To the basic horizontal branch of the rear foot 22 is attached to removably the end part of a rigid support rod

  23 arranged longitudinally, the front end of which is

  delivered to the middle part of the front foot 21. This support rod 23 is dimensioned so as to hold the rear foot 22

  tilted back. Attaching the front foot 21 to the upper

  port 13 of the seat 10 is produced by clamps 21a, the

  base parts are forced against the widened upper part

  front foot 21 by bolts 22a.

  The rear foot 22 has the upper parts of its lateral branches in the form of flat, vertical plates

  provided with through holes, through which the former

  corresponding end of a shaft 14 fixed laterally to the ex-

  corresponding rear end of seat 10.

  Consequently, although the rear foot 22 is articulated

  abut from above on the ends of the shaft 14 which project laterally from the seat, it is prevented from moving thanks

to the support rod 23.

  The backrest 30 is defined by a main frame, having a generally rectangular outline, having a part

  main upper plane, extending from the upper edge

  laughing to a level somewhat above the seat, and

  a lower part, also flat, forming a slight angle

  re-entrant in relation to the upper part. The bars-

  side rails of the lower part are crossed respec-

  tively by the ends of the shaft 14, between the seat and the lateral branches of the rear leg 22, to allow the

  angular movement of folding the backrest 30, and the

  lower tie of the backrest extends downward relative to

  the geometric axis of articulation 14-14, by a part of the

  dre having an inverted trapezoidal contour. File 30

  further takes a plurality of cross members 31 to support the lining (padding) and two end side bars 32, in the same plane as the upper part 30 of the frame and connected to the latter only to the upper part, by 1 'intermediary lateral extensions of the upper horizontal seat bar. These two extreme side bars 32 of the

  seat extend up to the height of the arms 40 of the chair-

long.

  Each arm 40 consists of a plate 41 having an inverted U-shaped profile of low height, the flaps of which are provided with small rear extensions crossed by small

  hinge pins 42 having their ends fixed respectively

  at the lower end of the extreme sidebar

  32 of the seat, and to the inner side bar of the back frame-

  sier 30. On the front parts of the side flaps of the plate

  that 41 are articulated the ends of a pair of rigid rods 43. The internal rod of each pair of rods 43 is articulated at its lower part on a horizontal fixed shaft

  44, constituting the front edge of the seat 10 and extending laterally

  outwardly from the latter. In the configurations shown in FIGS. 1 to 4, on the shaft 44 is articulated the lower end of a part 45 in the shape of an inverted L, which is fixed at its upper part to the outer rod of each

pair of rigid rods 43.

  As can be seen in FIGS. 1 and 2, the arms are mounted in a sort of parallelogram with respect to the backrest and the seat, the inclination of the front rods 43 of the arms being greater than that of the backrest 30, so that , when the file "goes down", the arms 40 come closer

  gradually from the seat and tilt forward and slightly

  downward (Figure 2). In the configuration illustrated in FIGS. 1 to 4, the footrest 50 is constituted by a flat, U-shaped frame having internal crosspieces 51 arranged in diagonals, and the extreme upper parts of its lateral branches connected by a crosspiece 52 and also articulated on the lower end of the rigid rods

  outside 43, by means of small rear pins

ticulation 48.

  Between element 45 and the outer rod of each pair

  re of rods 43 is articulated a horizontal shaft 46 to which

  che the upper part of a spring 47, the end of which

  lower is attached to the cross member 52 of the footrest 50.

  The automatic movement of the footrest is obtained by a mechanism comprising a small lever 15 whose end

  lower is articulated to the support 13 for seat 10, and its ex-

  upper end forming a joint for the rear end

  first of a small rod 55, the front end of which is articulated

  on the crosspiece 52 of the footrest 50.

  On the middle part of the small lever 15 is articulated the front end of an elongated rod 35, the rear end of which is articulated on the lower edge of the backrest frame

  30. With this extremely simple arrangement, when the back-

  sier 30 is folded from the "vertical" position of Figure 1 to the "lying" position of Figure 2, the elongated rod 35 forces the small lever 15 to rotate forward, pushing

  thus the footrest to its more angular positions

  lifted, via the small rod 55, which is

  core provided with a plurality of holes to allow better

  their adjustment of the footrest stops 50. The small lever

  , which is also provided with a plurality of longi-

  tudinaux, allows to multiply the angular displacements

  of the footrest 50 as a function of a certain angular displacement

file area 30.

  According to the embodiment shown in Figures 8, 9 and 10, on the middle part of the small lever 15 is articulated

  the front end of a small arm 35a, in the form of an extension

  ment of the elongated rod 35, this small arm 35a having its ex-

  rear end hinged to the front end of the rod

  length 35. A coil spring 8Q is arranged around a

  extension of the pivot pin between the small le-

  vier 15 and the small arm 35a, this spring having its ends made up of radial rods whose curved ends

  are mounted around the pivot pins between the pe-

  rods 55 and the small lever 15, and between the small arm

  a and the elongated rod 35, respectively.

  The spring 80 permanently biases the small arm a and the small rod 55 towards a position in axial alignment with the elongated rod 35, causing the elongated rod 35 and small arm 35a assembly to behave like a single rigid rod during the maneuver of the chaise longue between the "vertical" position shown in Figure 1 and the "lying" position

shown in figure 2.

  However, after the backrest 30 and the footrest have reached the position shown in FIG. 2, where the small lever 15 bears against a stop 13a, fixed to the lower base part of the U-shaped support 13, the production of the elongated rod in two parts 35 and 35a allows that, by forcing the backrest still downwards, these two parts are articulated with respect to each other, against the force of separation of the end rods of the spring 80, making it is possible for the backrest to be lowered to the "completely" position

  lying down "shown in Figure 9, without changing the

  feet, which remains in its highest position.

  In the configuration shown in FIGS. 5, 6 and 7, the structure of the footrest 50 receives on its front face a support plate 56, on the upper and middle parts of which the ends of two arms 57 and 58 are articulated arranged in parallel to each other and to the planes defined by the footrest structure 50 and the support plate 56, these arms 57 and 58 are articulated on a part of the footrest structure so as to define a system of hinge and attachment to sides of parallelograms between the plate

  56 and the structure 50, allowing the first to move

  cer, from a position of non-service, entirely covering the structure 50 which is in the "vertical" position (FIG. 5), and

  a service position, where it is moved longitudinally-

  ment forward with respect to the structure 50 (FIG. 6). It is possible that one of these arms 58 mentioned

  extends beyond its point of articulation with the structure

  re of footrest 50 to receive, in articulation, the

  mite of a rigid rod 52 having its opposite end articulated

  lée on a point of the seat structure 10, arranged in re-

  line and lower in relation to the axis of articulation of the footrest structure on the front part of the structure

seat.

  In the configuration shown, this indented point

  seat structure 10 is defined by a pivot point

  ment 61 on a rigid rod 60 fixed to the lower part of the front edge of the seat, so as to project downwards

and the back.

  Thus, when the footrest structure 50 is pro-

  gressively high, the increasing distance between the end of the elongated arm 58 and the point on the rod 60, in association with the rigidity of the elongated rod 59, causes the corresponding rotation of the two arms 57 and 58 around their points of articulation on structure 50, pushing the support plate

forward.

  The angle of the backrest 30 can be adjusted

  naked by any suitable device, such as, for example, that which consists of a hydraulic cylinder 70 having one of its ends articulated on the lower edge of the backrest frame 30, and at the other end a rod 71 projecting from 1 free end articulated on the support 13 of seat 10, the

  rod 71 being surrounded by a return spring 72.

  The jack 70 is divided inside by a piston into two chambers filled with hydraulic fluid, and communicating with each other by means of a valve passage controlled by the user. The headrest 60 comprises a rectangular planar frame having a width equal to that of the backrest frame, this frame ill

  comprising two lower rods 61 in the same plane,

  placed inside two guide elements 62 and 63 fixed to the internal upper edge of the backrest frame 30. On one of the rods and at the lower part thereof articulates the extreme free part of a transverse lever 65, with its opposite end part articulated on the rear part of the opposite side part of the backrest frame 30. The lever 65 extends beyond its point of articulation on the rod 61 of the headrest, pass through a vertical guide 66 (Figure 2) attached to the backrest and slightly beyond the lateral limits of the backrest, for manual operation by the user

  in the vertical direction. Guide 62 of the operating rod

  vre 61 is shaped as a tightening sleeve which acts by rubbing

  ment around this rod to prevent sagging

  vertical tane by the action of gravity on the whole.

  The seat 10, the backrest 30, the arms 40, the

  feet 50 and headrest 60 are padded as shown

in figure 11.
