The present invention operates as follows.
The base member (10) fixed on the toilet body (101) of the western-style toilet (100) and the toilet seat receiver (20) disposed above the base member (10) include the toilet body (101). It is connected by the link mechanism (30) of the raising / lowering part (30, 40) arrange | positioned by the side surface side, and the toilet seat receiver (20) raises / lowers when the link mechanism (30) raises / lowers. Since the toilet seat (102) of the western toilet (100) is attached to the toilet seat receiver (20), the toilet seat (102) moves up and down as the toilet seat receiver (20) moves up and down. Power for raising and lowering the toilet seat (102) is supplied from the power unit (50) to the link mechanism (30) via the connecting means (40).

  The link mechanism (30) of the elevating part (30, 40) has a first link member (31) and a second link member (32), which intersect in an X shape. Since the intersection part (33) of the first link member (31) and the second link member (32) is axially connected, the first link member (31) and the second link member (32) are this axial connection part. Can be rotated with respect to each other. Of both ends of the first link member (31), one end (31a) connected to the front (21a) of the toilet seat receiver (20) can be slid back and forth, and the other end (31b). ) Is axially connected near the rear part of the base member (10), and can be rotated around this axially connected portion.

  Of the two end portions of the second link member (32), one end portion (32a) connected to the front portion (11a) of the base member (10) can be slid back and forth, and the other end portion (32b). ) Is axially connected near the rear end of the side surface (21) of the toilet seat receiver (20), and can be rotated around this axially connected portion.

  That is, in the link mechanism (30) of the elevating part (30, 40), both the first link member (31) and the second link member (32) have their end portions located on the front side of the toilet body (101) slid back and forth. And can be rotated. Moreover, the edge part located in the back side of a toilet bowl main body (101) can be rotated by each axis | shaft connection part.

  The link mechanism (30) can be raised by winding the cable (42) by the operation of the power unit (50). The front end (42a) of the cable (42) is fixed to the front part (11a) of the base member (10), and the pulley (41) provided at one end part (32a) where the second link member (32) slides. Since the rear end (42b) side is housed in the power unit (50) side after being hooked on the front side, the cable (42) pushes the pulley (41) backward when the cable (42) is wound up. As a result, one end (32a) of the second link member (32) provided with the pulley (41) slides backward and rotates in the direction in which the other end (32b) rises. Thereby, the rear part (23) side of the toilet seat receiver (20) to which the other end part (32b) is connected rises.

  By this sliding and rotation, the first link member (31) is simultaneously rotated in the direction of rising about the connecting shaft (36). Since the one end (31a) rises while sliding backward, the front part (21a) of the toilet seat receiver (20) to which the one end (31a) is connected rises. In this way, the toilet seat (102) can be raised together with the toilet seat receiver (20).

  When the winding of the cable (42) is loosened from the state where the toilet seat receiver (20) is raised, the one end portion (31a) of the first link member (31) is lowered while sliding forward, and the first link member (31 ) Rotate in the direction of falling forward.

  By this sliding and turning, the one end portion (32a) of the second link member (32) slides forward. Thereby, the 2nd link member (32) rotates in the direction which falls backward, and the other end part (32b) of the 2nd link member (32) descends. In this way, the toilet seat (102) is lowered together with the toilet seat receiver (20).

  When the lifting parts (30, 40) are arranged on both sides of the toilet body (101), the size of each lifting part (30, 40) is reduced and the toilet seat receiver (20) is lifted on both the left and right sides. Therefore, the lifting / lowering operation is stable.

  According to the toilet seat lifting / lowering apparatus of [1], [2] and [3] according to the present invention, all of the base member, the toilet seat receiver, the lifting / lowering section and the power section are disposed on the toilet body, and the width direction of the apparatus Since the power section that spreads out is arranged on the rear side of the toilet body that is a dead space, the width of the device can be reduced and the user of the wheelchair can improve the convenience of use, The space in the toilet can be used effectively and can be made compact in appearance.

  As in the toilet seat lifting / lowering device of [4], the tip of the cable as the connecting means is fixed to the base member, and is provided at one end of the second link member slidably connected to the front of the base member. The front end side of the cable may be hung on the front side of the pulley, and the rear end side may be housed so as to be able to be wound on the power unit side, thereby extending the cable regardless of the slide position of the second link member as it goes up and down. Since the direction is always rearward, a direction changing member such as a relay pulley for changing the direction of the cable is not necessary, and the apparatus can be miniaturized correspondingly.

  In addition, as in the toilet seat lifting device of [5], it is preferable to arrange the lifting parts on both sides of the toilet body body, so that the size of each lifting part can be reduced and the both sides of the toilet seat receiver are raised and lowered. A stable lifting operation can be obtained.

Press (towards direction). As a result, when the connecting shaft 37 slides in the direction of the arrow A within the slide hole 14, the second link member 32 simultaneously rotates in the direction of rising with the connecting shaft 37 as the center of rotation. At this time, the first link member 31 connected to the second link member 32 by the connecting shaft 34 rotates in the direction of rising with the connecting shaft 36 as the center of rotation simultaneously with the rotation of the second link member 32. . At the same time, the connecting shaft 35 connected to the slide end 31 a of the first link member 31 slides in the direction of the arrow A in the slide hole 24.

  The first link member 31 rotates about the connecting shaft 35 even if the connecting shaft 35 slides in the slide hole 24, and the second link member 32 rotates the connecting shaft 38. Since it rotates about the center, when the first link member 31 and the second link member 32 are rotated so as to rise, the toilet seat receiver 20 rises without tilting.

  As shown in FIG. 7, when the connecting shaft 35 is slid halfway in the direction of the arrow A in the slide hole 24, the first link member 31 and the second link member 32 are raised more than in the case shown in FIG. The toilet seat receiver 20 is not inclined and is raised by the amount of the first link member 31 and the second link member 32 being raised.

  When the cable 42 is further wound, the second link member 32 further rotates in a direction in which the connecting shaft 37 rises while the connecting shaft 37 slides in the slide hole 14 in the arrow A direction. At the same time, the first link member 31 further rotates in the direction in which the connecting shaft 35 rises while sliding in the direction of arrow A in the slide hole 24. When the connecting shaft 37 and the connecting shaft 35 slide in the slide hole 14 and the slide hole 24 to the end in the direction of arrow A and stop, the first link member 31 and the second link member 32 stop rotating in the rising direction. . The state at this time is shown in FIG. 5 and FIG. 6, and the toilet seat receiver 20 is in the most elevated position without being inclined.

  From this state, when the power source unit 50 loosens the winding of the cable 42 and the cable 42 is pulled out, the link mechanism 30 moves downward without tilting the toilet seat receiver 20 by performing an operation reverse to the above description. Let The link mechanisms 30 are arranged on both sides of the toilet body 101 and perform the above operations at the same time, so that a stable lifting operation can be obtained.

  In this way, the toilet seat lifting / lowering apparatus 1 can be lifted and lowered smoothly between the position shown in FIGS. 5 and 6 and the position shown in FIG. 8 without tilting the toilet seat receiver 20. That is, the toilet seat 102 attached to the toilet seat receiver 20 can be raised and lowered smoothly without being inclined.
