Definitions

  • the present invention relates to armchairs and more particularly to wheelchairs which must be easily foldable and take up less volume when they are folded.
  • Foldable wheelchairs are already known, such as that described in DE-B-1176315, very schematically comprising in their essential elements two frames forming an armature, two foldable arches connecting the two armatures, these two arches and the armatures producing two parallelograms joined by one on their side, these two parallelograms being deformable, thus allowing the two reinforcements to be brought together.
  • These reinforcements are advantageously in the form of a rectangular frame and are preferably made of hollow tubes of section, for example square. One of these tubes appears, cut out, in 3 on the frame 1.
  • These two frames each support rolling means such as for example a small wheel 4 and 5 idle mounted and another wheel of larger diameter 6 and 7, ensuring the rolling of the wheelchair, in particular by hoops 8 and 9 fixed on the rims of these wheels 6 and 7.
  • these wheels include tires mounted on the chamber, as is clearly seen in the figure at 10 in the section of the cutaway section.
  • the two frames 1 and 2 are held relative to each other by a first spacer 11 foldable into two parts 12 and 13 around an axis 14.
  • These two parts affecting the shape d '' a hoop, made of material like rigid tubes, are rotatably fixed at each end around axes 15 and 16, respectively on the frame 1 and an axis 17 and 18 on the frame 2, not visible on the figure.
  • the frames are made of tubes forming rigid parallelograms which are generally in planes perpendicular to the rolling plane of the chair.
  • the axes 15 and 16 and the axes 17 and 18 are located on two straight lines which are also perpendicular to this running plane.
  • the two arches 12 and 13 are located in, respectively, two planes perpendicular to the running plane defined above, and which will be able to pivot relative to the plane of the frames around, each, two straight lines passing respectively through the couples d axes 15, 16 and 17, 18, while constantly containing a common straight line, that which passes through the axis of rotation 14 connecting the two arches 12 and 13.
  • the frames are shaped in a frame and their vertices 19 and 20, which are in the high position on the sides of the frames 21 and 22, respectively supporting the large diameter wheels 6 and 7, are rotatably mounted around respectively two axes 23 and 24, two uprights 25 and 26 which are able to support.
  • a flexible canvas 27 which will constitute the file for the person who will use this armchair.
  • each upright comprises a curved part at its upper end forming handles 28 and 29, respectively for the uprights 25 and 26.
  • These two uprights additionally comprise two plates respectively 30 and 31 integral with the bars 32, 33.
  • the wheelchair further comprises connecting means between each upright 25 and 26 with each part 12 and 13 of the spacer 11, so that when these uprights pivot around axes 23 and 24 respectively, they drive into another rotation of the two parts 12 and 13 around the pairs of axes 15, 16 and 17, 18 respectively.
  • lever 40 and 41 integral at one of their ends with the upright at points 42 and 43 respectively different from the axes of rotation 23 and 24.
  • the other end of these levers is pivotally mounted in 44, 45, at the end of a rod 46 and 47 (the rod 47 is not visible in Figure 1).
  • the rod is located inside the tubes 3 of square section forming the frame of the frames, and which allow the rods, also having a corresponding square section, to be able to slide inside these tubes 3 which form housings for said rods.
  • the other ends of the rods 46 and 47 opposite to that connected to the lever 40 and 41 each support a link 50 and 51, the two ends of which are rotatably mounted on axes, on the one hand, on the rods 46 and 47, and, d on the other hand, on the two parts 12 and 13 of the spacer 11.
  • These rods make it possible to transform the translational movement of the rods into a rotational movement for the parts 12 and 13.
  • the levers 40 and 41 and the rods 50 and 51 cooperate with their respective rods through windows 81, 82 (FIG. 2) produced in the wall of the tubes 3.
  • a first spacer 11 has already been described connecting the two frames 1 and 2. However, it is well known that only one is not sufficient for good stability of a wheelchair, in particular a wheelchair, for the physically handicapped.
  • the two uprights support at their ends 55 and 56 opposite those of the handles 28 and 29 a second spacer 57 foldable into at least two rigid parts 58 and 59 around an axis of rotation 60.
  • These two parts are produced by example in steel or aluminum tubes.
  • the axis of rotation 60 is advantageously parallel to the two bars of the uprights. This assembly thus forms two planes articulated around this axis 60, which therefore obliges the two bars to remain constantly parallel even while operating only one when the chair is being folded.
  • the two parts 58 and 59 are L-shaped and are supported respectively in the uprights 25 and 26 so that they can pivot around the axis of the bars 32 and 33, and advantageously in these to be able to obtain rigidity to rotation about an axis perpendicular to these bars.
  • the bases 61 and 62 of the two parts 58, 59 respectively extend the two bars 32 and 33.
  • Each base 61 and 62 is connected to the frames by connection means constituting a connecting rod system 63 and 64.
  • Each connecting rod 63 and 64 comprises a projecting lug 65, 66, fixed integrally at 73, 74, on the base 61, 62, and a connecting rod 67, 68, one end of which is pivotally mounted on a fixed point of the armatures by a first ball joint 69, 70, and the other end of which is pivotally mounted on the end of the tab 65, 66, by means of a second ball joint 71, 72.
  • These connecting means thus make it possible, when the uprights pivot around axes 23 and 24 respectively, in particular in the direction of arrow 75, to move the ends 55 and 56 away from the reinforcements and therefore points 73, 74.
  • the ball joints 69, 70, 71 and 72 thus make it possible to absorb the torsions of the connecting rods relative to the elements to which they are linked.
  • the links 64 and 65 move away from the reinforcements but the fixed length of the links 67 and 68 obliges the links 65 and 66 to rotate since the distance from the axes 69, 71 , and 70, 72, is fixed.
  • the swivel ment of the two uprights as described above also causes the rotation of the two arches around the axis 14 in the direction of the bringing together of the two frames.
  • the chair should include a flexible canvas which will be suspended between the two frames 1 and 2 on the top of the two frames, this canvas will be the seat means and which will allow more easy folding of the chair.
  • This chair may also include armrests and footrests; these latter means being known in themselves, will not be described.
  • the chair illustrated in Figure 1 folds and unfolds as follows.
  • FIG. 2 represents, seen from the side, the armchair according to FIG. 1, on which appears the illustration of the decomposition of the movement of the various constituent elements of the armchair.
  • the uprights 25 and 26, and the spacer 11 occupy the positions P i .
  • a force is then exerted, for example manually, in the direction of arrow 75 on one of the uprights. They tilt by rotation and can simultaneously occupy the intermediate position P 2 .
  • the first spacer "breaks" by rotation of the two arches around the axes 15, 17 and 16, 18, and their common axis 14 and, on the other hand, the second spacer 57 also breaks by rotation around the bases 61, 62, and the common point 60.
  • positions P 3 in the figure represent the folded spacers, which are in planes parallel to those of the reinforcements and therefore this mode of representation, according to the figure, means that these spacer parts appear in projection in their true size. (in proportion of course with the other elements of the chair).
  • the chair can advantageously include locking means in its unfolded position.
  • These means can be, for example, controllable hooks secured to the armatures, which can be snapped onto lugs secured, for example to the ends 55 and 56 of the uprights 25, 26.
  • the armchair as produced has many advantages, in particular as regards its size. Indeed, it does not for example have a spacer parallel to the first at the level of the large wheels 6 and 7, which means that the two frames 1 and 2 can be perfectly pressed against each other. This is advantageous since it is at this level that the large diameter wheels are located, which are of considerable bulk. This absence of a spacer at this level therefore contributes to reducing the overall width.
  • Another advantage lies in particular in the fact that the connections and the articulations of the spacers all being linked directly or indirectly with the two uprights, it is then possible to fold or unfold the chair with one hand and with what side whatever, by acting indifferently on one or the other of the amounts.
  • the connecting means between the second spacer 57 and the two frames 1 and 2 are essentially constituted by sets of rods 63, 64, mounted on ball joints.
  • FIGS 3 A and B show the elements of the chair necessary for understanding the present invention.
  • Figure 1 there is shown the structure of the chair comprising two frames like the frame 1 formed of a frame, at a corner of which is articulated in rotation about an axis 23 a post 25 consisting of a bar 32 completed by a curved part forming a handle 28.
  • This hollow tubular bar 32 supports a base 61 of the spacer 57, this base being able to rotate on itself in this bar 32.
  • FIGS 3 A and B show an advantageous embodiment of these locking means.
  • These means comprise a pawl 300 integral with a rod 301 which can slide in bearing means which are advantageously constituted by the very interior of the bar 32 of the upright 25.
  • This rod 301 then crosses at its two ends, on the one hand, the bar 32 by a slot 302, the emerging part 303 of this rod being advantageously bent, relatively close to the handle 28, to form a gripping means in a goal which will be explained below and, on the other hand, by the end 55 of the bar 32 and through the bar 61 by a guide hole 304.
  • this rod 301 is subjected to the action of a pushing force, given by a spring 305 cooperating with a pin 306 secured to the bar 32 and a shoulder 307 secured to the rod 301, this shoulder abutting against the end 308 of the base 61 when the spring is fully relaxed, to prevent the rod from coming out of its housing.
  • this shoulder can be shaped so that its side wall slides against the inner wall of the bar 32 and thus forms one of the elements of the bearing means guiding the rod in its translations.
  • the chair further comprises a hook 309 secured to the side 21 of the frame of the frame 1 against which the upright 25 bears when the chair is unfolded.
  • This hook is, in the illustrated embodiment, formed by a solid piece complementary to the pawl 300 which, in this case, assumes the shape of a stirrup.
  • This operation blocks the amount which can no longer, therefore, undergo rotation for folding the chair.
  • the embodiment of the pawl and the hook must be taken in the widest sense, that is to say of two pieces of any kind which, when they cooperate with each other, prevent relative movement of a piece compared to each other.
  • the pawl has a female function
  • the hook has a male function, and that, of course, these two functions could be very easily reversed and even combined.
