  As shown in FIGS. 3 to 11, the opening / closing slide means A mainly includes an opening / closing slide rod 3, a slide rail 30, and an elastic body 35. The slide rail 30 is fixed to a fixing plate or the like on the outer peripheral surface of the bathtub body T, and is provided in a direction orthogonal to the opening / closing line of the bathtub opening / closing part G. The opening / closing slide rod 3 is formed with a slide rod portion 31 and a distal end side bulging portion 32. The slide collar 31 is configured to be slidable with respect to the slide rail 30. Specifically, the gate-shaped slide pinching portion 31 a fixed to the slide collar 31 slides while wrapping the both side groove portions 30 a and 30 a of the slide rail 30. The elastic body 35 may be provided directly on the opening / closing slide rod 3 without being provided on the link 8 described later (see FIG. 5C).

  As shown in FIGS. 5 and 10, the tip side bulge portion 32 is formed with an inclined piece 32 a on the upper surface side. Specifically, it is formed in a straight line so that the tip side is lower and the height gradually increases from there. The inclination may be formed in an arc shape in an uneven shape. In addition, a large elongated hole 32 b is provided in the distal end side bulging portion 32 in parallel to the longitudinal direction of the slide flange 31. The length is formed to be equal to the stroke length (predetermined length: 2L) when the drive arm 5 makes one rotation [see FIG. 7A]. Further, an elongated hole portion 32c for pivotally supporting a later-described link is provided below the distal end side bulging portion 32.

  As shown in FIGS. 5 and 12, the driving means B mainly includes a rod 4, a driving arm 5, and an electric motor 51. A shaft piece 41 at one end (left side in FIG. 5) of the rod 4 is slidably provided in the large elongated hole 32b of the distal end side bulging portion 32. The other end (right side in FIG. 5) of the rod 4 is pivotally supported by a shaft 42 at the tip of the drive arm 5. That is, the shaft piece 41 at one end (left side in FIG. 5) of the rod 4 is slid and pulled in the large slot 32, and the other end (right side in FIG. 5) of the rod 4 is driven. It is pivotally supported at the tip of the drive arm 5 by the electric motor 51. A sensor disc 52 is fixed to the shaft of the electric motor 51 (or fixed to the drive arm 5). A cutout 52a of about 45 degrees to about 60 degrees is provided on the outer periphery of the sensor disk 52, and the optical sensor 53 is configured to operate at this location.

  As shown in FIGS. 5, 10 and 11, the stopper means C is mainly composed of a horizontal collar 61, a drooping collar 62 on the tip side, and an elastic body as viewed from the side as the stopper collar 6. 63 and the middle of the horizontal flange 61 is pivotally supported by a shaft 64 so as to be rotatable on a fixed plate on the outer peripheral surface of the bathtub body. A front end roll portion 65 is provided at the lower end of the hanging hook piece 62, and a rear end roll portion 66 is provided at the rear end of the horizontal hook portion 61. The distal end roll portion 65 is configured to roll on the inclined piece 32 a of the distal end side bulging portion 32.

  Further, the front end roll portion 65 is moved by the elastic force of the elastic body 63 (specifically, the tension coil spring 63a) provided between the shaft support 64 and the rear end roll portion 66. It is configured to be able to roll while pressing on the inclined piece 32 a of the distal end side bulging portion 32. In addition, the tip end roll portion 65 is not provided at the lower end of the drooping hook piece 62, and it can be slid while pressing on the inclined piece 32a of the tip side bulging portion 32 as a slidable portion. Sometimes.

  As shown in FIGS. 5, 12, and 13, the stopper release means D mainly includes a stopper release cam 7, a driving pulley 72, a driven pulley 71, a timing belt 70, and a tension pulley 73. It is configured. The driving pulley 72 is fixed to the drive shaft of the electric motor 51, and the driven pulley 71 is fixed to an appropriate location on the outer peripheral surface of the bathtub body. Further, a stopper release cam 7 for releasing the stopper rod is attached to the outer surface of the driven pulley 71 in a bar shape. In particular, the stopper releasing cam 7 pushes down the rear end roll portion 66 of the stopper rod 6 against the elastic body 63, so that the tip-side bulge that the hanging-shaped flange portion 62 has been engaged with is engaged. It is released from the jaw part of the part 32.

  The diameter of the driven pulley 71 is configured to be twice that of the driving pulley 72. That is, the pulley ratio is 2. Accordingly, the stopper release cam 7 (or the driven pulley 71) is set to rotate once for every two rotations of the drive shaft (or the driving pulley 72) of the electric motor 51. In particular, at the first rotation, the stopper release cam 7 does not operate at all, and at the second rotation, the stopper release cam 7 operates (see FIG. 8).

  As shown in FIGS. 1 to 4, the opening / closing slide means A for locking the hook 2 and the stopper means C for stopping the operation of the opening / closing slide means A have the same structure. Are provided in two stages up and down. In particular, the lower opening / closing slide means A is referred to as lower opening / closing slide means A ′, and the lower stopper means C is referred to as lower stopper means C ′. The open / close slide rod 3 of the open / close slide means A is linked to the lower open / close slide rod 3 'via the link 8, the link rod 9a and the lower link 8'. As a result, the upper opening / closing slide means A and the lower opening / closing slide means A ′ operate in synchronism even when the driving means B and the stopper release means D are not present on the lower side. Similarly, the stopper rod 6 of the stopper means C is also linked to the lower stopper rod 6 ′ of the lower stopper means C ′ via the link rod 9b.

  The opening and closing of the bathtub opening / closing part will be described. At this time, since the upper and lower two stages perform the same operation synchronously, only the upper stage will be described with reference to FIGS. Thus, it may be configured by an opening / closing device having only an upper stage or only a lower stage. Further, when the diameter of the driving pulley 72 is 1, the diameter of the driven pulley 71 is 2. That is, the driving pulley 72 rotates twice and the driven pulley 71 rotates once.

<Close operation and lock mechanism of bathtub opening / closing part>
First, at the start of the locking process of closing the bathtub opening / closing part G, the opening / closing slide means A, driving means B, stopper means C, stopper releasing means D and manual stopper releasing means E are in the state shown in FIG. At this time, the bathtub opening and closing part G is closed as shown in FIGS. At this time, it is in a lightly closed state, and there is a gap of about 5 cm inside and outside. In this manner, the bathtub opening / closing part opening / closing switch S1 of the operation panel is pressed in a state where the bathtub opening / closing part is closed, and the electric motor 51 is started. With this rotational drive, the driving pulley 72 and the drive arm 5 rotate clockwise as shown in FIG. In contrast, the driven pulley 71 and the stopper release cam 7 are interlocked and rotated clockwise by the timing belt 70. Then, the rod 4 moves rearward (right side) by the rotation operation of the drive arm 5.

  The open / close slide rod 3 is also pulled backward (right side) against the elastic body 35 by being pulled by the rod 4, and the inclined piece 32 a of the distal end side bulging portion 32 of the open / close slide rod 3 is moved to the stopper rod. 6 is pushed up the tip end roll portion 65 at the lower end of the hanging collar piece portion 62 (see FIGS. 5B and 6A). At this time, the drooping flange piece 62 (tip roll portion 65) of the stopper rod 6 is configured to be pressed downward by the elastic force of the elastic body 63.

  When the rotation operation of the drive arm 5 proceeds and the rod 4 further moves rearward (right side) so that it is 170 degrees inside and outside (immediately before 180 degrees) from the beginning as shown in FIG. The top of the tip side bulging portion 32 of the slide rod 3 exceeds the position of the tip roll portion 65 at the lower end of the hanging rod piece 62 of the stopper rod 6, and at that moment, the hanging rod piece 62 and the tip roll The portion 65 serves to hold the tip-side bulged portion 32 of the opening / closing slide rod 3. That is, as shown in FIG. 6C, the tip roll portion 65 is locked to the arc-shaped portion 32 d of the tip side bulged portion 32. At this time, the bathtub opening / closing part G is in close contact with the bathtub body T. This is the locked state (see FIGS. 6B and 6C). Further, the rotation operation of the drive arm 5 advances, and the locked state is maintained even if the drive arm 5 rotates 180 degrees as shown in FIG.

  Then, the rotation operation of the drive arm 5 proceeds and rotates 360 degrees (one rotation) as shown in FIG. At this time, the top rod 4 moves forward (left side) while the opening / closing slide rod 3 is kept locked by the stopper rod 6. That is, the shaft piece 41 of the rod 4 moves from the right end to the left end of the large elongated hole 32b of the distal end side bulging portion 32. By this operation, the element for preventing the opening / closing slide rod 3 from moving to the left side is the locking of the hanging rod piece 62 to the arcuate portion 32d of the tip side bulged portion 32 of the opening / closing slide rod 3 It has become only. That is, in the state of FIG. 7B, the operation of the electric motor 51 and the rod 4 does not contribute to the movement of the opening / closing slide rod 3. With such an operation, the locking process ends. That is, the driving pulley 72 rotates once and the driven pulley 71 rotates one half, and the locking process ends.

<Opening operation of bathtub opening / closing part>
First, the bathtub opening / closing part opening / closing switch on the operation panel is pressed in a state where the bathtub opening / closing part is completely closed and locked. This state is also when the locking process ends or the unlocking process starts in FIG. Then, as shown in FIG. 8A, the electric motor 51 starts to rotate, and the driving pulley 72 and the drive arm 5 start to rotate in the second round. On the other hand, the driven pulley 71 and the stopper release cam 7 rotate in conjunction with each other from the half rotation end position. The rod 4 moves rearward by the rotation of the drive arm 5.

  Further, the electric motor 51 rotates once and three quarters, the driven pulley 71 also rotates, and the stopper release cam 7 rotates about three quarters from the beginning. This state is a state immediately before unlocking as shown in FIG. When the electric motor 51 further rotates a little, as shown in FIG. 9 (A), the rear end roll portion 66 of the horizontal flange portion 61 of the stopper rod 6 is pushed down. By this momentary operation, the opening / closing slide rod 3 is instantaneously moved to the left by the tensile force of the elastic body 3. This state is a “state immediately after unlocking”. Immediately before the opening / closing slide rod 3 is completely moved in the left direction, a gap is formed between the tip of the hook 2 in the latch hole 1 of the bathtub opening / closing portion, and the hook 2 is separated from the latch hole 1 by its own weight. It starts to fall and is set at a right angle.

  Further, the electric motor 51 makes two rotations, and the rotation ends as shown in FIG. At this time, the unlocking process ends. As described above, at the same time as the second rotation of the electric motor 51 is completed, the stopper release cam 7 (the driven pulley 71) is rotated by one half of the latter half. In this state, the bathtub opening / closing part can be freely opened. This state is the same as the above-mentioned “at the start of the locking process” (see FIG. 5A).

<Emergency bathtub opening and closing operation>
In this apparatus, when the electric motor 51 does not operate at the time of a power failure, the bathtub opening / closing part can be opened manually. As shown in FIG. 7 (B), in the case of a power failure with the bathtub opening / closing part G locked, when the emergency unlocking knob 100 is pulled up once, in FIG. 6 is rotated in the clockwise direction, and the opening / closing slide rod 3 is instantaneously moved to the left by the tensile force of the elastic body 35 and is unlocked by the operation at this moment. At the same time, the lower stopper 杆 6 ′ that is interlocked is also lifted, and the hook 2 is removed from the latch hole 1 in the same manner as the opening / closing operation by the electric motor 51, and the bathtub opening / closing portion G is opened.

<Each detection operation>
As a detection mechanism of the driving means B, the first rotation and the second rotation of the electric motor 51 are managed. The first rotation is a bathtub opening / closing section closing operation, and when the sensor disk 52 makes one rotation, it is detected by the operation of the optical sensor 53 through the notch 52a. The second rotation is a bathtub opening / closing portion opening operation, and when the sensor disk 52 rotates twice, the optical sensor 53 is sensed by operating through the notch 52a. Further, as a mechanism for detecting the opening / closing slide rod 3 of the opening / closing slide means A, the movement of the first sensor plate 36 is detected by the first optical sensor 37 and the operating position of the opening / closing slide rod 3 is confirmed. Further, as a detection mechanism of the stopper rod 6 of the stopper means C, the movement of the second sensor plate 67 is sensed by the second optical sensor 68 and the operating position of the stopper rod 6 is confirmed.

  The features of the embodiment of the present invention include the following matters. The sliding means A for opening and closing is fixed to the link mechanism that performs linear motion with the rotational power by the driving means B and interlocks the opening and closing with the hooks 2 at the upper and lower stages using the restoring force of the elastic body 63 (spring). The stopper means C is provided, and the release of the fixing is performed by a stopper release cam 7 connected to the rotational power. Further, the device is such that the emergency opening / closing slide means A is unlocked by the emergency unlocking knob 100 by manual operation, the hook 2 is opened, and the bathtub opening / closing part G is opened.

  Further, the effects of the embodiment of the present invention include the following matters. When the hook 2 is closed and locked to the latch hole 1 and the stopper rod 6 is operating, the opening / closing slide rod 3 is fixed and the closed state of the hook 2 is maintained (locked state). There is no need to provide a mechanism for holding the opening / closing slide rod 3 on the rotational power side by the driving means B. In addition, when the electric motor 51 does not operate due to a power failure or failure, when the hook 2 is closed, the closed state of the hook is maintained (locked state), thereby opening the bathtub opening / closing unit unintended by the user. The movement can be avoided. When the electric motor 51 makes one rotation and the locking process ends (FIG. 7 (B)), the stopper 杆 6 (stopper means C) is released by the emergency lock release knob 100 by manual operation, and the hook 2 It is possible to open the bathtub opening / closing part G in the open state, and to exit the bathtub. That is, in the present invention, since there is a mechanism for fixing the opening / closing slide rod 3 with the stopper rod 6, the bathtub opening / closing portion G can be opened even when the electric motor 51 does not operate.

  Furthermore, in the embodiment of the present invention, the driven pulley 71 provided with the stopper release cam 7 for releasing the stopper rod 6 for fixing the opening / closing slide rod 3 is connected to the rotational power, thereby opening and closing. Two types of operations, that is, linear movement of the slide rod 3 and release of the fixing by the stopper rod 6 can be performed by one rotational power (electric motor 51), and the cost of the entire apparatus can be reduced.
