When the shampooing operation is completed, when the release pedal A2c is depressed, the coupler A3 in the locked state is unlocked and the coupler A3 in the coupled state is released by depressing the coupler pedal A2b of the lock device B2. Then, the locking members B2 unlock the engaging members A2d and A2e, and the lid B1a is closed and movable (see FIG. 5).

The outline of the operation of the present invention has been described above. Next, a detailed structure will be described together with FIG. The same reference numerals as those shown in FIGS. 1 to 5 denote the same members, and a description thereof will be omitted.
First, the structure of the driving means A2 and the locking means B2 for opening the lid B1a of the underfloor unit B and then fixing the shampoo unit A to the underfloor unit B will be described. 6 to 10 show the entire shampoo unit A, and a column 2 is attached to a pair of bars 1 to which casters A1a are attached, and a shampoo ball A4 is attached to the upper end of the column 2.

  A guide rail (not visible by a slide plate 2b, which will be described later) is attached to the column 2 side, and a slide plate 2b is attached to the guide rail so as to be movable up and down. A frame-shaped lock plate 2c is attached to the slide plate 2b. A lock pedal A2a is attached. A pair of conical engagement members A2d are attached to the rear (left side in FIG. 6) of the lock plate 2c, and the engagement members A2e are also attached to the front (left side in FIG. 7). In addition, two springs 2d are stretched between the slide plate 2b and the support column 2, and springs are biased in a direction in which the slide plate 2b is always pulled up.

  In the shampoo unit A configured as described above, when the lock pedal A2a is depressed against the spring force of the spring 2d, the slide plate 2b is lowered and the engaging members A2d and A2e are moved directly below to be described later. Enter under floor unit B.

  Next, the entire underfloor unit B of FIGS. 11 to 13 will be described. The underfloor unit B is accommodated under the floor, and the cover plate B1 is covered on the opening surface at the same height as the floor surface. . When the cover plate B1 is opened with a square hole facing the lid B1a that covers the upper surface of the hot and cold coupler 3 and the drainage coupler 4 to which hot water and water are supplied, and the engaging member A2d is lowered to apply a pressing force. A hole that faces a pair of descending pressing members B1b and a hole that faces an opening / closing lid B1c that is opened when the engaging member A2e descends and a pressing force is applied are opened.

  12 and 13 show the entire underfloor unit B excluding the hot water coupler 3 and the drainage coupler 4, FIGS. 14 to 16 show a link mechanism for opening and closing the lid B1b, and FIGS. 17 to 22 show a locking device. It is the figure which showed the link mechanism of B2, First, the mechanism for opening lid | cover B1b is a pair of pressing member B1b always pushed up with the spring force of the spring 4, and one end was pivotally supported by this pressing member B1b. First and second links 5, 6, a first auxiliary link 7 whose one end is pivotally supported by the first other end, and a second one whose one end is pivotally supported by the other end of the second link 6 The auxiliary link 8, one end of which is pivotally supported by the casing of the underfloor unit B and the other end of which is pivotally supported by the lid B1b, and one end pivotally supported by the casing and the other end of the lid B1b. The open / close link 10 is pivotally supported, and the other end of the auxiliary link 8 is pivotally supported at one end. Klink 11 as being more configurations.

  The other ends of the first and second links 5 and 6 are attached with rollers 5a and 6a guided by rails attached to the casing, and the tip of the auxiliary link 7 is a U-shaped link. 9 is pivotally supported at a portion close to the rotation fulcrum. Further, an intermediate portion of the lock link 11 is pivotally supported by a fixed link 12 that is formed upright from the casing. Further, a blocking piece 11a is formed at the upper end of the lock link 11 for blocking the rotation of the opening / closing lid B1c pivotally supported by the housing.

  The operation of the link mechanism for opening the lid B1a will be described. The shampoo unit A is moved above the underfloor unit B, and the lock pedal A2a is positioned with the engaging member A2d positioned above the pressing member B1b. Is depressed, the pressing member B1b starts to descend as the lock pedal A2a descends. When the pressing member B1b is lowered, the rollers 5a and 5b of the first and second links 5 and 6 are guided by the rail and moved rightward in FIGS.

  Here, when the roller 5a of the first link 5 moves in the right direction, the auxiliary link 7 pivotally supported by the roller 15a rotates the U-shaped link 9 in the direction of the arrow (the right end is the rotation fulcrum). Since it is moved, the lid B1a moves leftward while ascending. At this time, since the opening / closing link 10 also rotates with the movement of the lid B1a, the opening / closing link 10 and the U-shaped link 9 serve as a parallel link to move the lid B1a in a substantially horizontal state. At the position, the lid B1a is retracted from above the hot water coupler 3 and the drain coupler 4.

  On the other hand, when the second link 6 moves to the right, the auxiliary link 8 is moved to the right, so that the lock link 11 is rotated counterclockwise with the shaft fulcrum with the fixed link 12 as a fulcrum. Accordingly, the blocking force that has prevented the counterclockwise rotation by the spring bias of the opening / closing lid B1c that has been in contact with the blocking piece 11a of the lock link 11 is released, and the opening / closing lid B1c is as shown in FIG. The engagement member A2e can be passed by being rotated counterclockwise.

  When the pressing force by the engaging member A2d is released, a spring force by the spring 4 is applied to the pressing member B1b. Therefore, when the pressing member B1b is raised by the spring force, the first and second links 5, By returning 6 to the original position, the lid B1a and the open / close lid B1c are closed to return to the initial state.

Next, details of the locking device B2 will be described with reference to FIGS. 12, 13, and 17 to 25. FIG.
Reference numeral 13 denotes a first upright plate that stands up from the bottom surface of the underfloor unit B, and the lower bent portion of the first link 14 formed in an inverted U shape is pivotally supported on the upright plate 13. One end of the second link 15 is pivotally supported. One end of the third link 16 is pivotally supported on the housing side of the underfloor unit B, and the other end is pivotally supported on one end of an auxiliary link 19 described later. A pin 14 a is formed at an upper bent portion of the first link 14, and the pin 14 a faces a long hole 15 a formed in the second link 15. A bolt-shaped shaft rod 14 b is integrally attached to the pin 14 a, and a spring 15 b is stretched between the head of the shaft rod 14 b and the end portion of the second link 15.

  A lock link 17 is pivotally supported on the distal end side of the first link 14, and a spiral spring 17a is attached to the pivotally supported shaft so as to rotate the lock link 17 clockwise. A roller 17 b is attached to the tip of the lock link 17. A connecting link 18 is pivotally supported on the shaft to which the spiral spring 17a is attached, and an auxiliary link 19 pivotally supported by the connecting link 18 is pivotally supported on one end of the third link 16.

  The other end of the release link 21 whose one end is pivotally supported by the lower end of the release pin 20 is pivotally supported at the pivot point of the third link 16 and the auxiliary link 19. The release pin 20 is supported by the housing of the underfloor unit B so as to be movable up and down, and is flush with the surface of the cover plate B1 when unlocked, and the surface of the cover plate B1 when locked. It protrudes slightly more.

  A roller 18a guided by a guide portion 22a of the second upright plate 22 is attached to the tip of the connection link 18, and a second connection link 23 is pivotally supported on the roller 18a. One end of an L-shaped third connection link 24 is pivotally supported on the connection link 18, and the other end of the connection link 24 is pivotally supported on the lower end of the lock rod moving link 25. The upper end of the lock rod moving link 25 is pivotally supported by the rear end of the lock rod 27 slidably guided by the guide tube 26.

  The other end of the connecting link 23 is pivotally supported at the other end of an auxiliary moving link 28 whose one end is pivotally supported by an upright plate 22 erected from the underfloor unit B. A pin 28 a is fixed to the upright plate separated from the upright plate 22, and a long hole 25 a formed in an intermediate portion of the lock rod moving link 25 faces the pin 28 a. The guide tube 26 is pivotally supported by two pivot points so as to be swingable, and is pivotally supported by the separated upright plate to which the pin 28a is fixed. The link 29 is pivotally supported.

  The lower end of the link 29 is pivotally supported by the swing link 30, and the swing link 30 is pivotally supported by the upright plate 22 and stretched between the casing of the underfloor unit B. A rotational force in the clockwise direction is applied by the spring 30a. A roller 30 b is attached to the tip of the swing link 30.

  Next, the locking operation will be described based on the above-described link mechanism. The states of FIGS. 17 and 22 are states in which the lock pedal A2a is depressed and the engaging member A2d is in contact with the pressing member B1b. Since the engaging member A2d has a conical shape, the engaging member A2d is guided so as to be centered in the middle of passing through the hole of the cover plate B1 even if the position of the engaging member A2d is slightly deviated from the pressing member B1b. To facilitate a smooth descent. In the above state, the spring 15b pivotally supported by the shaft rod 14b biases the shaft rod 14b and the pin 14a in the direction of the spring force 15b. This spring force 15b is decomposed in parallel (Y direction) and perpendicular (X direction) to the direction of the axis connecting the rotation fulcrum of the link 14 and the pin 14a.

  Here, if the Y component of the spring force 15b is the spring force Y and the X component is the spring force X, the pin 14a attached to the link 14 receives the spring force X, so the link 14 has a rotational moment in the direction of arrow a. Will occur. Due to this moment, the link 14 tries to rotate in the direction of the arrow a, but the shaft (supporting urethane is wound around the shaft) supporting the link 14, the lock link 17 and the connecting link 18 is the second link 15. The link 14 is brought into a non-rotatable state, and therefore the link 14 is not rotated in the direction of arrow a.

  In this state, when the lock pedal A2a is further depressed, the pressing member B1b is further lowered, so that the link 14 is rotated in the counterclockwise direction. At this time, the rotation as shown by the arrow b about the rotation fulcrum of the link 14 is performed. A moment is generated. When this rotation reaches the position shown in FIG. 23, the direction of the spring force 15b and the direction of the spring force Y coincide with each other, so the spring force X component becomes zero. If the link 14 rotates as it is and reaches the position shown in FIGS. 19 and 24 and passes the dead point, a spring force X in the opposite direction is generated, and the link 14 springs regardless of the lowering of the pressing member A2d. The spring force from 15b is received.

  As a result, the roller 17b of the lock link 17 moves to the engagement member A2d side along the guide portion B1c, and the roller 17b is engaged with the engagement stage formed on the engagement member A2d as the engagement member A2d is lowered. Therefore, the engagement member A2d is locked by the lock link 17 (see FIGS. 20 and 25).

  On the other hand, when the link 14 is rotated in the counterclockwise direction, a counterclockwise rotational force is applied to the auxiliary moving link 28 via the connecting link 18 and the connecting link 23. Since the end is pivotally supported by the upright plate 22, the pivot point of the auxiliary moving link 28 and the connecting link 23 is pushed downward. A roller is provided at the shaft fulcrum. Also, since the connecting link 18 moves, the connecting link 24 also moves to the left. Therefore, the lock rod moving link 25 is rotated clockwise around the pin 28a, and the tip of the lock rod moving link 25 is moved. The shaft-supported lock rod 27 protrudes from the guide tube 26 and is engaged with the engagement step portion A2d1 of the engagement member A2e.

  In the locked state shown in FIG. 20, the roller 17a of the lock link 17 is engaged with the engaging member A2d, the lock rod 27 is engaged with the engaging member A2e, and the shampoo unit A is below the floor unit B. In this state, in particular, the engaging member A2e and the lock rod 27 are merely engaged, and therefore, when an external force is applied to the shampoo unit A, there is a possibility that rattling may occur. There is.

  Therefore, by pressing the roller 30b of the oscillating link 30 against the spring force of the spring 30a by the moving member 31 that descends by depressing the coupler pedal A2b to connect the coupler described in detail later, the oscillating link 30 30 is rotated counterclockwise. When the swing link 30 is rotated counterclockwise, the guide tube 26 is rotated clockwise via the link 29, so that the lock rod 27 applies a push-down force to the engagement member A2e. The flange 27 and the engagement member A2e are more firmly engaged. Further, since the pivot point of the auxiliary moving link 28 and the connecting link 23 is pushed down, it is pushed down by the moving member 31, so that the connecting link 23 moves the connecting link 18 to the left and the roller 17b is engaged. Applying a force to push down the engaging step A2d1 of the combined member A2d, the roller 17b and the engaging member A2d are more firmly engaged, and therefore, rattling is prevented even when an external force is applied to the shampoo unit A. (See FIG. 21).

Next, a link mechanism for connecting the cold water / hot water / drainage coupler of the shampoo unit A and the coupler of the underfloor unit B will be described with reference to FIGS.
The coupler pedal A2b is attached to the distal end of the coupler link 32, and the distal end of the coupler link 32 is fixed to a rotating shaft 32b that is rotatably supported by an attachment piece 32a that stands up from the base side of the shampoo unit A. Yes. A connecting link 33 formed integrally with the coupler link 32 is also fixed to the rotating shaft 32b. The other end of the connection link 33 is pivotally supported by the second link 34. The tip of the second link 34 is pivotally supported by a water supply / drainage block 35 supported so as to be movable up and down with respect to a slide rail 2f provided on the support 2 side.

  A lock rod 36 is attached to the water supply / drainage block 35 and is configured to move up and down as the water supply / drainage block 35 moves up and down. Four bearing holes 35a are formed at the four corners of the water supply / drainage block 35, and four support rods 37 are supported in the bearing holes 35a with play (can be tilted about 3 degrees) in the horizontal direction. Yes. A flexible head 38 is pivotally supported so as to be able to move up and down at the lower portion of the support rod 37, and a spring 39 is interposed between the flexible head 38 and the water supply / drain block 35.

  A water / hot water coupler 40 and a drain coupler 41 are attached to the flexible head 38. Further, a spring 2f is stretched between the water supply / drainage block 35 and the column 2, and the water supply / drainage block 35 is always urged upward by a spring. Reference numeral 42 denotes a water / hot water coupler fixed on the underfloor unit B side, and 43 denotes a drainage coupler which is connected to a water supply, a water heater and a trap through the under floor. The coupler 40 is connected to the mixing faucet A5, and the drainage coupler 41 is connected to the shampoo ball A4.

  Next, in order to prevent the water supply / drainage block 35 from being pulled up by the spring 2f in the state where the water supply / drainage block 35 is lowered and the couplers 40, 41 on the shampoo unit A side are connected to the couplers 42, 43 on the underfloor unit B side. Next, the locking means 44 for locking the lock rod 36 will be described with reference to FIGS.

  This locking means 44 is attached to the middle part of the column 2, and as shown in FIG. 8 and FIG. 27, a rotary link 44a having a bent shape in which the middle part is pivotally supported on the fixing plate 2g of the column 2, A synthetic resin lock cam 44c connected to one end of the rotating link 44a via a connecting link 44b, and stretched between the rotating link 44a and the fixed plate 2g, and the rotating link 44a is spring-biased counterclockwise. And a roller 44e attached to the other end of the rotary link 44a. The lock cam 44c is pivotally supported by the fixed plate 2g.

  The roller 44e is in sliding contact with a release plate 44g that descends when the release pedal A2c is depressed. The release plate 44g is composed of a width detail and a wide portion (see FIG. 29). When the release pedal A2c is not depressed, the roller 44e abuts the width detail and the rotation link 44a and the lock cam 44c are as shown in FIG. When the release pedal A2c is depressed, the roller 44e comes into contact with the wide portion and the rotary link 44a and the lock cam 44c are in the positions indicated by the solid lines in FIG. 44c rotates to allow the lock rod 36 to be lifted by the spring 2f.

  Next, the operation of the link mechanism for connecting the couplers described above will be described. When the coupler pedal A2b is depressed, the coupler link 32 connected to the coupler pedal A2b and the connecting link are rotated on the rotary shaft 32b. While rotating counterclockwise. When the connecting link 33 is rotated counterclockwise, the water supply / drainage block 35 is lowered by the second link 34 against the spring force of the spring 2f, so that the flexible head 38 attached via the support rod 37 is used. Descends.

  The couplers 40 and 41 attached to the flexible head 38 start to descend toward the couplers 42 and 43 on the underfloor unit B side. Here, the couplers 40 and 41 have a range of about 3 degrees with respect to the horizontal direction. Since it can be freely changed by the spring 39, the couplers 40 and 41 and the couplers 42 and 43 are connected even when the couplers 42 and 43 on the underfloor unit B side are fixed at an angle. Therefore, the life of the couplers 40 to 43 and the members supporting the couplers can be extended without damaging them.

  Further, when the couplers 40 and 41 and the couplers 42 and 43 are connected (see FIG. 31), the locking means 44 for locking the lock rod 36 has the side surface a of the lock cam 44c when the lock rod 36 is lowered. Since the lock rod 36 is in contact with the side surface of the lock rod 36, the lock rod 36 is lowered in a free state. When the lock rod 36 passes through the lock cam 44c, the spring force of the spring 44d moves to the position of the phantom line in FIG. 28 to close the top of the lock rod 36. Therefore, even if the foot is released from the coupler pedal A2b. Since the lock rod 36 is fixed at the position of the lock cam 44c, the connection state between the couplers is maintained.

  It should be noted that in the above-described embodiment, it is possible to make a good connection even if the couplers 40 and 42 and 41 and 43 are shifted in position or at an angle by being movable in the horizontal direction. The case where the structure (water supply / drain block 35, support bar 37, flexible head 38, spring 39) is attached to the shampoo unit A side has been described, but the above-described operation can be performed even if this structure is attached to the underfloor unit B side. .

  32 and 33, the water and hot water couplers 40 and 42 are known in the present invention, but the drainage couplers 41 and 43 have a new structure. This is because the drainage coupler 43 on the underfloor unit B side does not close the connection portion with the coupler 41 when the coupler 41 on the shampoo unit A side is connected, thereby discharging into the drainage pipe. The steam of the hot water is trapped in the underfloor unit B, and the trapped steam is cooled so that it does not accumulate in the underfloor unit B as water.

  A valve body 43b that is always pushed up by a spring 43a is accommodated in the drainage coupler 43. A valve seat 43c made of packing is formed on the valve body 43b, and a valve seat 43d is also formed at the opening of the coupler 43 so that steam from the drain pipe enters when the valve seats 43c and 43d come into contact with each other. Not configured. In addition, 43d is a concave female part having packing.

  On the other hand, the drainage coupler 41 on the shampoo unit A side also houses a valve body 41b that is pressed down by a spring 41a. The valve body 41b is in contact with a valve seat 41d made of packing with respect to a male member 41c attached to the lower end of the drainage coupler 41 to maintain a closed state. Reference numeral 41d denotes a male part that enters the recess 43d.

  In the drainage couplers 41 and 43 configured in this way, the valve seats 41c and 43c are in a closed state in a disconnected state, so that water accumulated from the shampoo ball A4 may leak to the outside. In addition, the steam from the drainage in the drainage pipe does not leak into the underfloor unit B.

  In this state, when the water supply / drainage block 35 is lowered by the above-described operation, the protruding portion of the valve body 41b of the coupler 41 comes into contact with the protruding portion of the valve body 43b of the coupler 43, and the valve body 41b resists the spring force of the spring 41a. The valve body 43b is pushed down against the spring force of the spring 43a. In addition, the male part 41d enters the female part 43d and is sealed with packing, but at this time, the valve body 41b rises and the valve body 43b descends. Therefore, as shown in FIG. Thus, the drainage discharged from the drainage coupler 41 flows into the drainage coupler 43 and drains into the drainage pipe.

Next, as described above, the shampoo unit A is locked and fixed to the underfloor unit B, and the hair washing work is performed by connecting the couplers 40 to 43, and the shampoo unit A is moved after the hair washing work is completed. Will be described.
Here, when the release pedal A2c is depressed, the release plate 44g starts to descend, and when the roller 44e comes into contact with the wide portion of the release plate 44g, the rotary link 44a rotates clockwise against the spring force of the spring 44d. Since it is rotated, the lock cam 44c is rotated counterclockwise as shown by the solid line in FIG. Accordingly, since the lock state of the lock rod 36 is released, the water supply / drainage block 35 is raised to the initial position by the spring force of the spring 2f and stopped.

  Further, when the release pedal A2c is stepped on, a pressing pin (not shown) that descends in conjunction with the lowering of the release pedal A2c pushes down the release pin 20, so that the release link 21 moves to the right and the third link 16, the roller 17b of the lock link 17 is moved away from the engagement step A2d1 of the engagement member A2d, and the lock between the lock link 17 and the engagement member A2d is released.

  Further, when the moving member 31 that is lowered by depressing the coupler pedal A2b is lifted, the swing link 30 is rotated clockwise by the spring 30a, and the guide tube 26 is rotated counterclockwise. The engagement state between the engagement member 27 and the engagement member A2e is released. In this state, as described above, the release link 21 moves to the right, thereby moving the connection link 18 to the right and the connection link 23 rotating the auxiliary movement link 28 counterclockwise. The lock rod 27 connected to the auxiliary movement link 28 is retracted, and the engagement with the engagement member A2e is released. Accordingly, the slide plate 2b rises due to the spring force of the spring 2d, but if the slide plate 2b rises before the release pedal A2c is stepped on and the water supply / drainage block 35 rises completely, the lid B1a of the underfloor unit B and the coupler 40 and 41 may come into contact with each other to generate a metal sound, and the lid B1a may not be closed.

  Therefore, in the present invention, the shock absorber shown in FIGS. 6 and 25 is provided to gently raise the slide plate 2c when the lock is released and the lifted state is reached. This shock absorber includes a rack 45 that is attached to the slide plate 2c and moves up and down, and a gear member that meshes with the rack 45 and gently lifts the rack 45, and is fixed to the support member 2 side. It is configured. Therefore, when the slide plate 2c is pulled up by the spring 2d, since the rack 45 is engaged with the buffer member 46, the slide plate 2c is gently lifted, and the above-described interference can be prevented.

  When the slide plate 2c gently rises and returns to the initial position in this way, the lock of the shampoo unit A to the underfloor unit B is completely released. Further, when the engaging member A2d is raised, the pressing member B1b is raised and the lid B1a is closed by an operation opposite to the above-described opening operation. Since the shampoo unit A is in a free state, the shampoo unit A can be moved to a predetermined position, or moved to the position of another under-floor unit B to perform the next hair washing operation. It will be.

  In the above-described embodiment, when the drainage couplers are disconnected, water accumulates in the underfloor unit due to water dripped from the drainage coupler on the shampoo unit side or due to poor connection with other couplers. There is a possibility that sewage will overflow from the underfloor unit.

  Therefore, in the present invention, as shown in FIGS. 11 and 34, when a predetermined amount of water has accumulated in the underfloor unit B, the water accumulated from the drain pipe is automatically drained through the trap. . In the figure, a drain hole (not shown) is formed in the trap 46 connected to the drain coupler 43, and a valve 46a for opening and closing the drain hole is attached to a rotatable shaft rod 46b pivotally supported by the trap 46. Further, the shaft rod 46b extends outward from the casing of the underfloor unit B, is bent along the casing, and a float 46c is attached to the tip thereof.

  Then, by storing the underfloor unit B in a case stored in advance under the floor (not shown), if the water is collected in the case, the float 46c is lifted and the shaft 46b is rotated. The valve 46a opens the opening hole by the rotation of the shaft rod 46b. Thereby, the water overflowing from the underfloor unit B into the case flows into the trap 46, and a certain amount or more of water does not accumulate in the case and the housing, and it is possible to prevent the malfunction of the link mechanism.

  In the above-described embodiment, the pedal for opening the lid B1a and the pedal for locking are the same, and the pedal used by the lock pedal A2d has been described. However, the lid B1a is opened. The pedal for locking and the pedal for locking may be separate.
