The control unit U is also connected to a manually operated hand switch 54 via a control signal line V.

  A base end portion of the flexible wire 4 is wound around the driven roller 72. The driven roller 72 rotates in both directions according to the operation of the elevating drive device 73 and winds or feeds the flexible wire 4. The comforter H rises or descends according to the rotation of the driven roller 72. If desired, a position detector such as a limit switch that detects the positions of the uppermost position (FIG. 17) and the lowermost position (FIG. 16) of the comforter H is disposed in association with the driven roller 72 or the flexible wire 4. Then, the detection result of the position detector is input to the control unit U. The control unit U restricts the raising / lowering range of the comforter H within the range of the highest position and the lowest position. As a modification, a movement restricting means such as a stopper for restricting the movement of the comforter H at the highest position and the lowest position may be provided in association with the driven roller 72 or the flexible wire 4.

  As shown in FIGS. 15 and 18, the horizontal movement device 74 has a transmission 74a having a worm gear mechanism, and a gear 74b is fixed to an output shaft of the transmission 74a. A gear 76 a meshing with the gear 74 b is fixed to the rotation drive shaft 76. The torque of the horizontal moving device 74 is transmitted to the rotary drive shaft 76 via the transmission 74a, the gear 74b, and the gear 76a, and the drive wheel 75 is rotated by the rotation of the rotary drive shaft 76. The rotary drive shaft 76 is rotatably supported on the edge of the horizontal substrate 71 by a bearing 76b. Therefore, the horizontal substrate 71 is entirely moved in the longitudinal direction (front-rear direction) of the bed B by the operation of the horizontal moving device 74. Move on. The most advanced position of the horizontal board 71 is shown in FIG. 19, and the last retracted position of the horizontal board 71 is shown in FIG. If desired, position detectors such as limit switches for detecting the positions of the most advanced position (FIG. 19) and the most retracted position (FIG. 20) of the horizontal substrate 71 are disposed on the horizontal substrate 71 or the horizontal guide member 15, The detection result of the detector is input to the control unit U. The control unit U limits the moving range of the horizontal substrate 71 to the range of the most advanced position and the most retracted position. Movement limiting means such as a stopper for limiting the movement of the horizontal substrate 71 at the most advanced position and the most retracted position may be disposed on the horizontal substrate 71 or the horizontal guide member 15. As the horizontal movement device 74, other mechanisms such as a rack and pinion mechanism and a lead screw mechanism may be used.

  The driven roller 72 is wound around the base ends of the two flexible wires 4. Each flexible wire 4 extends in the longitudinal direction of the bed B from the outer peripheral surface of the driven roller 72, and is turned downward by the pulley 100 of the tension applying device 80 and hangs down. The distal end portion of each flexible wire 4 is connected to the bedding suspension frame 40.

  The bedding suspension frame 40 is made of a wooden bar frame fastened by a fastening tool. As described above, the bedding suspension frame 40 is connected to the comforter H by the mooring member 2 and the flexible wire 3.

  FIG. 21 shows the structure of the tension applying device 80, and FIG. 22 shows the operation mode of the tension applying device 80.

  The tension applying device 80 includes a support member 81 fixed to the upper surface of the front end portion of the horizontal substrate 70, and a hollow swinging member 90 that is rotatably supported by a support shaft 91 of the support member 81. The swing member 90 applies tension to the vertical portion of the flexible wire 4 by pulling upward the vertical portion of the flexible wire 4 to which the load of the comforter H acts.

  The spring locking tool 82 protrudes from the top of the support tool 81, and one end of the coil spring 85 is locked to the locking tool 82. The other end of the spring 85 is anchored to a spring locking tool 86 projecting from the upper surface of the swing member 90. The spring 85 constitutes a biasing means that biases the swinging member 90 upward and rotates the swinging member 90 upward when the load of the comforter H acting on the vertical portion of the flexible wire 4 is reduced.

  A screw-type or bolt-type stopper 83 that restricts the rising of the swing member 90 is fixed to the locking tool 82. The stopper 83 protrudes obliquely downward from the lower surface of the engagement tool 82. The swing member 90 has a stopper abutting plate 84 at a position facing the lower end of the stopper 83. The abutting plate 84 is made of an elastically deformable cushioning material such as rubber or elastomer. A plate-like stopper 88 that restricts the lowering of the swinging member 90 is provided at the lower end of the support 81. A swing member abutting plate 87 that is opposed to the lower surface of the swing member 90 is fixed to the upper surface of the stopper 88. The abutting plate 87 is also made of a resiliently deformable cushioning material such as elastically deformable rubber or elastomer.

  The swing member 90 is made of a metal tube having a rectangular cross section, and has openings 93 and 98 on the lower surface of the distal end portion and the distal end surface. A horizontal support shaft 92 of the pulley 100 is fixed to the tip of the swing member 90. The flexible wire 4 extends from the base end opening 95 of the swinging member 90 into the hollow portion of the swinging member 90, turns downward via the circumferential groove of the pulley 100, and hangs down from the opening 93.

  FIG. 22A shows the neutral position (horizontal position) of the swing member 90. When the flexible wire 4 is wound around the driven roller 72 by the rotation of the driving roller 3 and moves in the direction of the arrow α, the flexible wire 4 raises the comforter H. As indicated by a broken line arrow E in FIG. 22B, the tension due to the load of the comforter H acts on the flexible wire 4. The tension of the flexible wire 4 works to rotate the swing member 90 downward. The swinging member 90 is rotated downward by the extension of the spring 85 and abuts against the abutting plate 87 and stops. This state is shown in FIG.

  When the flexible wire 4 is drawn from the driven roller 72 by the rotation of the driven roller 72, the flexible wire 4 lowers the comforter H. While the tension due to the load of the comforter H acts on the flexible wire 4, the flexible wire 4 maintains a tension state. The tension of the conductive wire 4 disappears rapidly. Due to the sudden loss of tension of the flexible wire 4, the flexible wire 4 is loosened or loosened. When the flexible wire 4 is loosened or slackened, a situation occurs in which the flexible wire 4 is entangled in a gap between members, which is not desirable. However, the swinging member 90 released from the tension of the flexible wire 4 is rotated upward by the elastic restoring force of the spring 85 as shown in FIG. Since the portion of the wire 4 is pulled upward, the looseness or slack of the flexible wire 4 is eliminated.

  Next, the operation of the bedding lifting apparatus 1 will be described.

  When a person on the bed B operates the horizontal movement device 74 by operating the hand switch 54, the torque of the horizontal movement device 74 is transmitted to the rotary drive shaft 76 via the transmission 74a, the gear 74b, and the gear 76a. The drive wheel 75 rotates. The rotation direction of the horizontal movement device 74, and hence the rotation direction of the drive wheel 75, is set by the hand switch 54.

  The driving wheel 75 and the driven wheel 76 travel on the upper surface of the lower flange portion 15a according to the rotational driving of the driving wheel 75, and move the lifting mechanism 70 back and forth between the most advanced position (FIG. 19) and the most retracted position (FIG. 20). Move in the direction. The pair of left and right flexible wires 4 move according to the movement of the lifting mechanism 70 and move the bedding suspension frame 40 and the comforter H in the longitudinal direction of the bed B. A person on the bed B can arbitrarily set the position of the elevating mechanism 70 and adjust the positional relationship between the body and the comforter H to an optimal state by operating the horizontal movement device 74 as described above.

  When a person on the bed B operates the lifting drive device 73 by operating the hand switch 54, the torque of the lifting drive device 73 is transmitted to the driven roller 72 via the drive pulley 73b, the endless belt 77, and the driven pulley 72b. The driven roller 72 rotates the flexible wire 4 in the winding direction or the feeding direction.

  When the elevating drive device 73 winds up the flexible wire 14 as shown by an arrow α in FIG. 15, the bedding suspension frame 40 and the comforter H ascend as a whole as shown by an arrow α in FIG. 16. When the comforter H rises to the highest position as shown in FIG. 17, the elevating drive device 73 stops and the comforter H stops at the highest position. The person on the bed B operates the hand switch 54 to stop the elevating drive device 73 at an arbitrary position below the highest position, and to put the comforter H at an arbitrary position between the highest position and the lowest position. It may be stationary.

  When the elevating drive device 73 feeds the flexible wire 14 as indicated by an arrow β in FIG. 15, the bedding suspension frame 40 and the comforter H are entirely lowered as indicated by an arrow β in FIG. 17. When the comforter H descends to the lowest lowered position as shown in FIG. 16, the elevating drive device 73 stops and the comforter H stops at the lowest lowered position. A person on the bed B operates the hand switch 54 to stop the elevating drive device 73 at an arbitrary position above the lowest position, and to put the comforter H at an arbitrary position between the highest position and the lowest position. It may be stationary.
