Definitions

  • the present invention relates to an armchair which can be transformed into a stretcher bed, particularly intended for the handling, transport, sleeping and putting in a wheelchair of incapacitated or able-bodied persons to be examined or operated on.
  • This chair is also intended for semi-disabled people who can be helped by an assistant to sit, stand or lie down.
  • a relaxation and relaxation seat with variable inclination comprising a set of two deformable rectangular frames, connected by horizontal crosspieces on which is stretched.
  • a canvas which are suspended laterally from two lateral supports resting on the ground; the suspension of the two frames forming the frame of this chair is taken, in the manner of a swing, at a horizontal transverse articulation axis, which is arranged very above the large upper side of each of the two frames .
  • Such an arrangement of the articulation and suspension axis does not allow the seat to be tilted more than a few degrees from the horizontal. Therefore, such an arrangement, applied to a bed chair for medical use of the type described in US-A-2 676 643 already mentioned, would not allow the chair to be brought into the upright position or in a standing position.
  • the present invention aims to remedy these drawbacks by proposing an armchair convertible into a stretcher bed comprising a backrest, a seat and a legrest bracing a set of two rectangular lateral frames, articulated at their apices and integral in their deformation, the sides of which anterior and posterior are extended upwards and downwards respectively to form the lateral frames of the backrest and legrest, the lower sides of which constitute the lateral frames of the seat, and the upper sides of which are each articulated around a horizontal articulation axis, normally perpendicular to the vertical planes passing through said frames, and integral with a base resting on the ground, this chair being characterized in that the articulation axis on the upper side of a frame is arranged either below or above the said side, at a distance from the latter not exceeding 10 centimeters.
  • the upper sides of the two frames form the armrests of the chair.
  • the articulation axis of the two armrests will normally be a common horizontal axis; in this regard, the two side frames of the chair will then have the same dimensions.
  • the horizontal articulation axis to which the chair is articulated or suspended, passes slightly below the plane defined by the armrests, and it is normally located along the latter , at respective distances of one third and two thirds of the length separating the points of articulation of said armrests on the rear and front sides of the two frames.
  • This configuration of the chair according to the invention considerably reduces the effort required to deform the chair or to tilt it forwards or backwards, so much so that it becomes very easy for the practitioner to raise the seat. vertically, or practically vertically, without the help of any auxiliary energy source usually required on armchairs of the same kind.
  • the practitioner is therefore able to very simply take charge of a person standing, or sitting upright, on his examination chair; when the caregiver presses his buttocks against the seat of the chair, the general balancing of the chair, and in particular the position of the horizontal articulation axis along the armrests, contributes to causing immediate deformation of the two rectangular frames of the chair, which allows the person to sit effortlessly, neither on his part, nor on the part of the practitioner.
  • the chair according to the invention can therefore be placed in any intermediate position, which can optionally be maintained, either manually, or by blocking means provided at various points on the chair.
  • the horizontal axis of articulation of the armrests can be locked in its rotation, normally free, so that the chair can be, for example, locked in a set of intermediate positions for which the seat is more or less inclined compared to the horizontal.
  • auxiliary energy source for example electric
  • auxiliary means for example electric
  • these means can be dimensioned according to criteria much less severe than on armchairs convertible into beds of the same kind.
  • the chair shown schematically in Figure 1 comprises a set of two articulated rectangular frames, of which only the left frame is visible in the figure, which are connected by transverse spacers, perpendicular to the plane of the drawing.
  • These two frames of the same dimension, each consist of an anterior side 1, a posterior side 2, a lower side 3 and an upper side 4 forming an armrest, and are integral in their deformations.
  • the joints on sides 1 to 4 between them are normally left free but at least one of them could be fitted with a locking means or a brake.
  • the front 1 and rear 2 sides are extended, respectively upwards and downwards, to constitute, with the transverse spacers, the frames supporting the backrest 5 and the leg rest 6 of the chair, more particularly visible on the Figures 2 to 7.
  • the lower sides 3 of the frames form, with the transverse spacers, the frame of the seat 7 of the chair. It will be observed that, in the case of an armchair / bed for medical use as described here by way of example, it is important that the backrest 5, the legrest 6 and the seat 7 are made in the form of removable cushions of a flexible material, such as high density foam, covered with a synthetic fabric which can be sterilized.
  • the two frames are suspended, or articulated, on a horizontal articulation axis 8, extending perpendicular to said frames, this axis 8 being integral with a base 9 resting on the ground.
  • This base 9, normally provided with rollers 10, can have any shape, but preferably comprises at least one horizontal cross member 11 at its lower part so as to form a stop disposed at the rear of the leg rest 6.
  • the horizontal cross member 11 is used in particular to limit the deformation of the frames, and therefore of the chair, so that the sitting position, for which the backrest 5 is the most raised, is comfortable for the patient.
  • the hinge pin 8 is normally mounted free in rotation, so that when the leg rest 6 abuts against the cross member 11 of the base 9 or, if necessary, against the ground, said leg rest 6 can slide against said cross member 11 causing the tilting of the seat 7 towards the front, which enables the chair to be placed in a seated upright position, as shown in perspective in FIG. 3, and diagrammatically in phantom in FIG. 1 .
  • the horizontal articulation axis 8 of the chair can be temporarily blocked, either directly or indirectly by auxiliary means blocking the position of the seat 7 in a horizontal, vertical or inclined position, intermediate between these two extreme positions.
  • At least one of the axes of articulation of the sides 1 to 4 of the deformable frames forming the frame of the chair can be temporarily blocked. In this way, it is possible to maintain the seat 7 of the chair at any angle.
  • the temporary blocking of the chair makes it possible to obtain all of the positions shown in FIGS. 4 to 6, namely a seated stretcher position ( fig. 4), an elongated stretcher position (fig. 5 and in phantom in figure 1) and an elongated position, inclined towards the front, making it possible to carry out a radiological examination (fig. 6).
  • the horizontal articulation axis 8 will be disposed at a distance from the posterior sides 2 of the frames approximately equal to a third of the length of the upper sides 4 forming armrests. It has been demonstrated that this proportion is perfectly suited to an automatic balancing of the chair towards a stable sitting position, when the patient is supported in the standing sitting position; in this case, it should be noted that the seat 7 must be free to rotate.
  • the horizontal articulation axis 8 passes just below the plane of the armrests, at a distance of a few centimeters, for example 15 millimeters, from the axis of the armrests, with a maximum about 10 centimeters; in this way, the chair is in a more unstable equilibrium position than if the horizontal articulation axis 8 were, on the contrary, located above said plane.
  • This arrangement facilitates the tilting of the seat 7 of the chair from one position to the other.
  • the seat 7 can be constituted by a wardrobe seat, superimposable, if necessary, on the bowl of a WC.
  • the height of the chair is adjustable by means of a conventional device with jacks, for example electrically controlled, or by means of a purely mechanical lifting system of the type of a jack or its analog.
  • the possibility of adjusting the seat height 7 explains in particular why it is generally necessary to have a cross member 11 at the front of the base 9, the leg rest 6 being able, in fact, in the highest position of the chair, no longer come into abutment against the ground when it is completely folded back (extreme sitting position).
  • the passage from one position to the other can be obtained in various ways, depending on whether the deformations of the chair and / or the inclination of the armrests are blocked or not.
  • the lifting of the chair from an extended stretcher position (fig. 5) to a verticalization position (fig. 2) can be carried out directly with the side frames (1,2,3,4) locked in their maximum extension position (bed position), in which case only the rotation of the armrests around the hinge pin 8 is left free.
  • the chair can be placed in a position derived from its seated or lying stretcher position so that the practitioner can perform a gynecological examination of the patient installed on the armchair.
  • the leg rest 6 is separated from the rest of the side frames forming the frame of the chair, which allows it to tilt, by simple gravity, against the base 9.
  • the backrest 5 can be indifferently in the upright, elongated or inclined position
  • the release of the legrest 6 towards the rear leaves the practitioner free to position himself facing the length of the chair.
