Definitions

  • the present invention relates to a lift chair, providing elderly or disabled people with assistance for the transition from the sitting position to the standing position, therefore for lifting, as well as for the reverse transition from the standing position to the sitting position. .
  • This chair allows such people to get up or sit down without the help of a third person and without physical effort.
  • the present invention seeks to remedy these drawbacks by providing a lifting chair of the "monocoque" type which is of simple and light construction, while having a particularly suitable movement and allowing possible adjustments as a function of the size of the user and / or desired seating position.
  • the subject of the invention is essentially a lifting chair comprising a base, an ascent-descent mechanism and a shell composed of a seat, a backrest and two armrests joined together in a monobloc assembly, an armchair in which the ascent-descent mechanism comprises two pairs of parallel lateral links, of very unequal lengths, which each connect the base to the shell so as to form a deformable quadrilateral, the two shorter links having their axis of articulation on the base located higher than the articulation axis of the two longer rods on the base, and behind this latter axis, while a motorized extendable device is articulated, on the one hand, with the following base a transverse axis and, on the other hand, to the shell along an axis coincident with the axis of articulation of the rods of shorter length to said shell.
  • the lifting chair object of the present invention and in particular the lifting mechanism of this chair which is reduced practically to four links, retain a very simplified structure.
  • the uneven length of the rods gives a remarkable movement during the climb: the chair shell rises first, remaining roughly parallel to itself, and only then does this shell tilt towards the before, while continuing its movement of elevation.
  • the two shorter rods are articulated at points located near the anterior edge of vertical lateral elements integral with the shell, while the two longer rods are articulated in points located near the rear edge of said elements, the latter comprising a series of holes which allow an adjustment in height of the points of articulation of the two pairs of rods.
  • the two pairs of rods are, for example, articulated on side legs, folded down, which belong to a plate fixed under the seat of the hull.
  • the series of holes provided in the latter case along the anterior and posterior edges of each lateral tab of the plate, allow an initial adjustment of the height relative to the ground of the shell, as well as of the inclination of the seat. with respect to the horizontal.
  • the two links of each pair are integral with the same transverse tube, mounted pivoting along its axis between the two lateral parts of the base, the two smallest links length also being interconnected by a cross member carrying in its middle a yoke to which is articulated, along an axis passing through the points of articulation of these rods on the shell, the upper end of a threaded rod moved axially by means a rotary nut coupled to an electric geared motor, the threaded rod being partially housed inside a housing secured to the geared motor and articulated to the base along a transverse axis.
  • the armchair shown in the drawing comprises a metal base (1), connected by two pairs of links, respectively (2 and 3), to a shell (4).
  • the base (1) has, on each side, a front upright (5) and a rear upright (6), interconnected by a right upper element (7) as well as by a bent lower bar (8).
  • the two bars (8) are connected to each other by two transverse elements (9), which with the middle parts of these bars (8) define a small rectangular central frame (10).
  • the shell (4) consists of a seat (11), a backrest (12) and two armrests (13), joined together as a single unit. Under the seat (11) is fixed a plate (14), the side parts of which are folded so as to form two vertical legs (15) facing downwards.
  • the two links (2) of the first pair are integral with the same transverse tube (16), pivotally mounted along its axis between the front parts of the two upper elements (7) of the base (1). These two links (2) are also interconnected at intermediate points. res of their length, by a crosspiece (17), while their ends remote from the tube (16) are articulated, at points (18), near the front edges of the two lateral tabs (15) of the plate (14).
  • the crosspiece (17) carries two ears (19), constituting a yoke whose axis (20) passes through the points of articulation (18) of the rods (2) on the lateral legs (15) of the plate (14).
  • the two links (3) of the second pair are also integral with the same transverse tube (21), pivotally mounted along its axis between the upper parts of the two front uprights (5) of the base (1).
  • the ends of these links (3) remote from the tube (21) are articulated, at points (22), near the rear edges of the two lateral tabs (15) of the plate (14).
  • the links (3) of the second pair have a length greater than twice that of the links (2) of the first pair.
  • the length of the links (2) (measured between the two articulation axes) is 12.5 cm
  • the length of the links (3) (measured between the two articulation axes) is 31.5 cm, which corresponds to a length ratio very close to 2/5.
  • the axis of articulation of the connecting rods (2) of shorter length on the base (1) is located above and behind the axis of articulation rods (3) of greater length on the base (1).
  • the axis of the tube (16) is located 8.5 cm higher than the axis of the tube (21), and 5 cm in back of the latter.
  • the central frame (10) of the base (1) is crossed by a housing (23) integral with an electric geared motor (24), which rotates a nut (not shown) cooperating with a threaded rod (25) of which the part outside the housing (23) is directed upwards.
  • the housing is linked to the two bars (8) by articulation along a transverse axis (26); the upper end of the threaded rod (25) is articulated to the yoke (19) along the axis (20).
  • Figures 1 to 4 make it possible to decompose the movement which brings the shell (4) from its lowest position to its highest position, this movement being controlled by the actuation of the gear motor (24) in the direction causing the lifting of the threaded rod (25) relative to the housing (23).
  • Each lateral tab (15) of the plate (14) has, along its front and rear edges, series of holes respectively (27 and 28), making it possible to position the articulation points (18 and 22) in various ways rods (2 and 3), to adjust the height and the inclination of the shell (4) in the low position.
  • the manual control of the gear motor (24) will advantageously be placed on one of the armrests (13) of the shell (4).
