Definitions

  • the object of the invention relates to the technical sector of variable positioning support means.
  • the traditional beds or the resting plans it is advantageous for the traditional beds or the resting plans to be adjustable in height in order to facilitate the care, and the transfers of the sick or the handicapped, as provided for in a hospital environment.
  • the height-adjustable medical beds are designed from a rolling frame carrying the mechanisms while the frame of the bed including the bed base, can be moved in height relative to the frame.
  • this movement is generally carried out manually or in a motorized manner, by the use of means first of all forcing it to move longitudinally between the high and low positions, that is to say according to a square or rectangular kinematics.
  • the support structure according to the invention overcomes these drawbacks, in that it makes it possible to obtain a loading surface that can be adjusted in height without increasing its size.
  • said structure is composed of a rigid lower frame bearing on the ground or on any frame, of an upper frame also rigid and connected to the lower frame, by a central device with a deformable and motorized parallelogram. on the one hand and by lateral support and holding members articulated between the two frames on the other hand.
  • the central device with a deformable parallelogram consists of four pairs of rods hinged transversely and two by two to the median crosspieces of the lower and upper frames, and hinged together in the middle of the distance between said frames where a driving means connected to the connecting axes of the pairs of lower and upper links, controls the movements of said pairs of links.
  • the support and retaining members are constituted by longitudinal bars articulated at their ends to the lower frame on one side and to the upper frame on the other side, and by four pairs of articulated rods. longitudinally and two by two near the ends of the side members of said frames, and hinged together in the middle of the distance between the frames, being linked in pairs by control bars.
  • the support structure is illustrated according to the basic embodiment which comprises a rigid lower frame (1) formed of longitudinal members (1a) and crosspieces (1b), a rigid upper frame (2) also formed of side members (2a) and cross members (2b).
  • the frame (1) has on each side legs (1c) extending upwards, while on the opposite side the frame (2) also carries legs (2c) extending downwards . Between the legs (1c and 2c) are mounted with free articulation of the longitudinal bars (3) for holding and connecting.
  • the frames (1 and 2) receive on each side and also with free articulation, pairs of upper links (4) and lower links (5) articulated together in (6).
  • the two pairs of rods 94 and 5) on each side are interconnected in the middle of the distance between the frames (1 and 2) by control bars (7) articulated at the axes (6), and transversely, said bars are joined by reinforcing crosspieces (8).
  • the frames (1 and 2) carry by their median crosspieces (1b1 and 2b1), a deformable parallelogram device which consists of four pairs of rods (9) articulated transversely and two by two to the crosspieces (1b1 and 2b1) and between them in the middle of the distance between the frames (1 and 2) by axes (10).
  • An actuator of the jack type (11) with low voltage electric motor (12) is interposed between the axes (10) of each of the two pairs of transverse rods (9) and controlled by the user using a well-known remote control device and not illustrated.
  • the pairs of links (9) are moved aside or brought closer together, thereby causing the frame (2) to rise or fall relative to the frame ( 1) resting on the ground or on any frame; this without modifying the overall dimensions, that is to say in a purely vertical manner.
  • the structure can replace a box spring in a traditional bed.
  • the frames (1 and 2) it suffices to make the frames (1 and 2) to the dimensions of a conventional bed base (one place or two places) and to fix or rest the lower frame (1) for example on supports such as brackets. (13) fixed inside the uprights or boats (B) of the bed themselves fixed to the head (T) and the foot (P).
  • the disabled person or the caregiver can thus easily modify the lying position (C) between two heights (h1-h2) according to his needs.
  • This possibility is particularly advantageous for transfers from the bed to a seat, to facilitate the passage from the reclining station to the standing station, to improve the working conditions of the nursing staff.
  • the upper frame (2) of the structure can receive a box spring in several parts C1, C2, C3 with variable geometry to serve as bust relief, leg folding, leg relief, well known.
  • the structure equipped with a plate (14) fixed on the frame (2) can serve as a massage, care or examination table, veterinary worktop or the like.
  • This table can receive under the frame (1) a fixed base (15) and / or rolling (16), grip handles (17) or other equipment necessary for this kind of application.
  • the structure can be equipped with an articulated ramp (18) on one side and a flap (19) on the other.
  • a disabled in a wheelchair (20) can easily access it, then activate the structure to mount it at the floor of a vehicle (V) and possibly move it (by remote control of a motor device acting on the wheels of the structure, in order to be able to get into the vehicle.
  • the structure can be used to bring loads (21) from an upper level (N1) to a lower level (N2) or vice versa.
