Definitions

  • the present invention relates to a device allowing the vertical displacement of a bed inside a structure and the immobilization of the latter in a high storage position, thus freeing up the lower space.
  • Document FR-A-2 616 309 discloses a device allowing the vertical displacement of a platform or a bed inside a structure.
  • the implementation of this device requires costly guidance systems.
  • the bed must be balanced by a counterweight of a mass equivalent to that of the bed, which is expensive and requires an adjustment which must be called into question each time the layout of the platform is modified.
  • the object of the present invention is to remedy the drawbacks presented by known devices and for this purpose it proposes a bed with vertical displacement which is of simple and inexpensive design, of reliable and practical operation, and which does not require for the control of its vertical displacement only a force very significantly less than the weight of the bed.
  • the device comprises at least two cords which each cooperate towards one end with a point of the bed, which pass over deflection pulleys carried by the guide structure and which are each associated at its other end with a means of displacement making it possible to apply pull-ups to said ropes to ensure the elevation of the bed in a horizontal position and vice versa, and it is characterized by the association, with each of said ropes, of a reducing hoist ensuring a reduction in the force to be applied to said means of movement in order to raise the bed to its high position. This force to be applied is thus divided by the coefficient of reduction of the hoists.
  • the displacement means comprises a counterweight
  • the mass of the counterweight is divided by the gear reduction coefficient of the hoists and can thus be less than or equal to half the mass of the bed.
  • the displacement means can be constituted by a handle to which the lifting ropes are fixed and on which engages by sliding and bears a removable counterweight.
  • a rigid guide structure has generally been designated at 1, inside which is intended to move a bed 2 vertically.
  • the structure 1 comprises four vertical beams 3 which are assembled at their upper part by four horizontal beams 4.
  • each hoist system comprising a pulley 6, 6 ', 6 ", 6"' carried by the bed 2 in the vicinity of each angle and a rope 7, 7 ', 7 ", 7” 'passing over said pulley and one end of which is fixed at a high point 8, 8', 8 ", 8” 'of the structure 1.
  • the four strings 7, 7', 7 ", 7” ' are returned, by means of pulleys carried by the structure 1, in an area where they are close to each other, mutually parallel and vertical. They are then joined together by means of a handle 9, which will be described later with reference to FIG. 3, on which a removable counterweight 21 fits.
  • the return of the rope 7 is provided by pulleys 10, 11 and 12, the return of the rope 7 'is effected by pulleys 13, 14, 15, that of the rope 7 "by pulleys 16, 17 and that of the rope 7" 'by pulleys 18, 19.
  • a traction exerted on the handle 9 makes it possible to obtain identical vertical displacements of the four angles of the bed 2, with a reduction in linear displacements which is equivalent to the reduction provided by the hoist systems.
  • a reduction can be provided so that the vertical displacement of the handle 9 is double the vertical displacement of the bed 2.
  • the handle 9 is elongated in the form of a slide, with a flared lower part 20.
  • the free ends of the four cords 7, 7 ', 7 ", 7"' are fixed by crimping to the upper end of the handle 9.
  • a removable counterweight made of cast iron, which has a central bore 22 over its entire height and which is open axially on one of its lateral faces.
  • the width of the internal bore 22 of the counterweight 21 is slightly greater than that of the body of the handle 9, and it goes by narrowing at the top of the counterweight.
  • the counterweight 21 rests on the flared lower part 20 of the handle 9, while the body of the latter is housed inside the bore 22 of the counterweight.
  • the counterweight is slid upwards along the handle body, then after a quarter-turn rotation the counterweight is released from the handle body thanks to the opening provided over the entire height of the lateral face of the counterweight. It is understood that the establishment of the counterweight on the handle will be carried out by the reverse operation.
  • the bed 2 rests on wedges, not shown in the drawing, the position of which can be adjustable.
  • the user pulls the handle 9 without having to exert a very reduced force.
  • the friction of the ropes and the pulleys is such that the bed holds itself in balance in all positions and in particular in the high position.
  • a high stop not shown in the drawing, limits the travel of the bed, and consequently that of the counterweight.
  • the user lifts the counterweight without again having to develop effort.
  • each rope 7, 7 ', 7 “, 7”' is fixed to the corresponding post 3 of the structure 1 by means of a clamping member 23 screwed onto the post 3 and to through which the rope 7 can only slide in one direction (direction of arrow A in Figure 4).
  • a clamping member 23 screwed onto the post 3 and to through which the rope 7 can only slide in one direction (direction of arrow A in Figure 4).
  • FIG. 5 a variant according to which the device for controlling the vertical movement of the bed 2, by handle and counterweight, is replaced by a winch 24, the ropes 7, 7 ', 7 ", 7"' s' simultaneously winding side by side on the single drum 25 of this winch.
  • the pulleys 12, 15, 17 and 19 are then no longer necessary.
  • the hoist system ensuring a reduction in half, the lifting force to be supplied by the winch will be reduced by half.
