Definitions

  • the present invention relates to a liftable bed, that is to say a bed whose bed base can be brought with the bedding which it supports to a suitable position above its base or fixed base in order to facilitate reordering. bed.
  • a liftable bed is known, the base to which the feet are fixed is connected to the movable frame intended to receive the bed base by at least two connecting rods pivotally mounted around axes fixed to said base and subjected to the action of tending elastic means. to separate from said base their end fixed to the movable frame, locking means retaining the frame in the low position against the base and unlocking means releasing the frame and allowing the actuation of the elastic lifting means.
  • French patent No 78 21520 relates to a lifting bed of this type, in which each connecting rod extends one of the ends of a helical spring working in bending around an axis fixed to the base, the other end of said spring. being itself linked to said base.
  • the present invention provides for this purpose a rocker pivotally mounted on the movable frame and returned to a rest position in which it projects by one arm relative to the bottom of the movable frame and cooperates by a part of the other arm with the means locking so as to oppose their disengagement, the rocker pivoting underweight the box spring when the latter rests on the frame, said pivoting eliminating the blocking action of the locking means.
  • the movable frame has a recess in which said arm is received when it is pushed back by the base, so that in this position the rocker is not projecting relative to the movable frame.
  • the bed of Figure 1 has a fixed base 100 and a movable frame 101 for receiving a box spring.
  • the head of the bed is on the left in the figure.
  • a pair of lifting members constituted by helical springs 102 working in bending, the turns of which are arranged around tubular axes 103 fixed transversely to the base 100.
  • the arrangement is symmetrical and two springs are arranged at the ends of each axis 103.
  • Each spring 102 is extended by a straight portion 104 arranged longitudinally, the angled end 105 of which is engaged in a bearing 106 fixed to the movable frame.
  • the part 104 is reinforced by a tubular element 107.
  • the spring 102 is connected to the straight part 104 in the vicinity of the base and that the end 108 of the spring is directed inward.
  • the end 108 is bent relative to the last turn so as to be parallel to the axis 103.
  • a piece 109 welded on the axis guides the end 108 allowing it to move axially while keeping it angularly.
  • the straight portions 104 constitute lifting rods and their length is chosen as a function of the desired lifting height.
  • Straps not shown, have their ends fixed respectively to the base and to the movable frame and retain the movable frame, in the raised position, against the action of the springs 102.
  • Rubber stops 110 are fixed on the base 100 to maintain a safety gap between the base and the movable frame 101 in the low position.
  • Screws 111 fix the frame 101 to the base 100 for storage and transport, and must be removed for use.
  • a locking device is mounted on the movable frame 101 at the head of the bed. It comprises a lock 112 mounted sliding in a longitudinal direction in a rectangular guide 113 fixed on a part 114 in the form of a bowl itself fixed to the movable frame 101. In the position shown, the spout 115 of the lock advances under the edge 116 of the transverse part of the base, which prevents the lifting of the mobile frame under the action of the springs 102. The lock is returned to this position by a spring 115a.
  • the latter is connected to a cable 117 on which traction can be exerted from an unlocking device mounted at the foot of the bed and described below.
  • a rocker 118 made of sheet metal is pivotally mounted on an axis 119 fixed to the piece 114 and returned to the position shown in dotted lines in FIG. 3 by a spring 120.
  • the end 121 of the rocker enters an opening 122 formed in the part 114 and engages in a transverse groove 123 formed on the upper face of the lock 112. The lock is thus prevented from moving under the action of a pull on the cable 117.
  • the bed base When the bed base is placed on the movable frame 101, it pushes by its weight the part 124 of the rocker and at the same time the end 121 comes out of the recess 123 of the lock and takes the position shown in solid lines. The lock can then be released by pulling on the cable 117.
  • a stamped 125 is made in the horizontal edge of the movable frame to receive the part 124 of the rocker and thus prevent it from projecting relative to the movable frame when the bed base is supported on the movable frame.
  • the unlocking device shown in Figures 4 and 5 allows to exert traction on the cable 117 for lifting.
  • the locking device is fixed to the mobile frame 101 at the foot of the bed and the reference 130 designates the angle which constitutes the end of the mobile frame, the horizontal wing carrying the reference 131 and the vertical wing the reference 132.
  • the cable 117 is fixed to the end of a lever 133 pivotally mounted by means of an axis 134 on the horizontal wing 131 and placed under it.
  • the end of the lever 133 opposite the eyelet 135 for fixing the cable 117 is in the form of a fork and passes between the wing 131 and a case 234 fixed to the wing 131, which serves to hold the lever 133 in position.
  • a second lever 136 is pivotally mounted by means of an axis 137 on the vertical wing 132.
  • An operating handle 138 is fixed to the lever 136 and at the opposite end, the lever has a finger. 139 which engages between the teeth 140 constituting the fork end of the lever 133.
  • the springs 102 are under tension, the straight parts 104 are substantially parallel to the ground, the movable frame 101 is supported on the stops 110 and retained by the latch 112.
