The groove portion 5c has a shape and a groove width into which the engaging end portion 15b of the engaging member 15 can be fitted. Since the corner portion of the engaging end portion 15b has an R shape, there is no risk of injury even if the engaging end portion 15b comes into contact with the body of a bather or a bathing assistant. Further, the engaging end portion 15b can be smoothly fitted into the groove portion 5c.

As shown in FIG. 3, the bogie fixing portion 5 has a pair of stepped portions 5d parallel to each other in the left-right direction on both sides in the front-rear direction as rail portions. The facing distance between the pair of stepped portions 5d corresponds to the facing distance between the pair of rail portions 7a provided in the mounting portion 7. The bogie fixing portion 5 is provided with a step portion 5d as a rail portion, thereby forming a third delivery member for delivering the mounting portion 10 between the bathtub 2 side and the transport vehicle 3 side.

The trolley fixing portion 5 is the first movement blocking that prevents the mounting portion 10 from moving in the left-right direction on the moving mechanism 6 except when the trolley portion 9 is connected and fixed to the bathtub 2 by the trolley fixing portion 5. A mechanism portion 17 is provided.

As shown in FIGS. 6A and 6B, the first movement blocking mechanism portion 17 has a lock member 17a whose upper end portion can protrude and retract from the carriage fixing portion 5 and the other end side integrated with the lower end side of the lock member 17a. The unlocking member 17b (integrated with the locking member 17a) supported by the shaft 17d and the spring member 17c for urging these in the clockwise direction (locking direction) are provided, and the unlocking member 17b is a carriage. The lock member 17a can protrude or retract from the through hole 5e formed in the groove portion 5c of the fixing portion 5, and the lock member 17a can protrude or retract from the through hole 5f formed in the main body portion 5b of the carriage fixing portion 5.

When the engaging end portion 15b of the engaging member 15 does not enter the groove portion 5c of the carriage fixing portion 5, the lock member 17a protrudes from the carriage fixing portion 5 by the urging of the spring member 17c, and the unlocking member 17b , Protruding from the groove portion 5c. In this protruding state, the first movement blocking mechanism portion 17 blocks the movement of the mounting portion 10 between the transport vehicle 3 side and the bathtub 2 side.

When the engaging end portion 15b of the engaging member 15 enters the groove portion 5c of the carriage fixing portion 5, the unlocking member 17b is pushed against the urging of the spring member 17c and rotates counterclockwise to the groove. The lock member 17a is retracted into the portion 5c, and at the same time, the lock member 17a is retracted into the carriage fixing portion 5. As a result, the first movement blocking mechanism unit 17 allows the mounting unit 10 to move between the transport vehicle 3 side and the bathtub 2 side.

A second movement blocking mechanism portion 18 is provided on the carriage portion 9 of the transport vehicle 3. The second movement blocking mechanism portion 18 blocks (locks) the movement of the mounting portion 10 on the carriage portion 9 except when the carriage portion 9 is connected and fixed to the bathtub 2 by the carriage fixing portion 5. ..

The second movement blocking mechanism portion 18 includes an unlocking member 18a that can integrally rotate around a shaft 18c provided on the engaging member 15, and a locking member 18b that is integrated therewith, and these are spring members 18d. (Biasing member) is urged in the counterclockwise direction. When the lock member 18b protrudes onto the lower surface of the mounting portion 10 by the urging of the spring member 18d and engages with the engaging portion 10d (first engaging portion) on the lower surface side, the mounting portion 10 is subjected to the trolley portion by the locking member 18b. It is prevented (locked) from moving on the trolley portion 9 and is prevented from falling off from the trolley portion 9.

Further, as shown in FIG. 7, a plurality of second movement blocking mechanism portions 18 are provided along the width direction of the engaging member 15 at intervals at which the bather cannot operate the second movement blocking mechanism portions 18 at the same time with one hand. (Two in FIG. 7) are provided. As a result, the following effects can be obtained. That is, when the carriage portion 9 is erroneously connected to the bathtub 2 from an oblique direction, the second movement blocking mechanism portions 18 and 18 start engaging with the carriage fixing portion 5 in a timely manner. Therefore, in the situation where the diagonal connection is completed, the second movement blocking mechanism unit 18 that has started the connection to the trolley fixing portion 5 may release the lock described above, but the trolley fixing portion will be released later. The above-mentioned unlocking is not performed on the second movement blocking mechanism unit 18 that has started to be connected to 5. As a result, it is possible to prevent the second movement blocking mechanism portion 18 from being erroneously unlocked when the carriage portion 9 is diagonally connected.

Further, since the second movement blocking mechanism unit 18 is provided as described above, when the second movement blocking mechanism unit 18 is not connected to the bathtub 2, due to misuse by the bather, all the second movement blocking mechanism units 18 at the same time, The unlocking of 18 is prevented, and the mounting portion 10 is prevented from falling off from the trolley portion 9.

When the trolley portion 9 is pushed in the two directions of the bathtub, the engaging end portion 15b of the engaging member 15 protruding from the side surface of the trolley portion 9 rises on the inclined portion 5a of the trolley fixing portion 5 against the urging of the spring member. Then, it enters the groove portion 5c of the bogie fixing portion 5 by the urging of the spring member. When the engaging end portion 15b enters the groove portion 5c, the carriage portion 9 is connected and fixed to the carriage fixing portion 5, and the first movement blocking mechanism portion 17 moves the mounting portion 10 from the transport vehicle 3 side to the bathtub 2 side. While allowing, the lock member 18b of the second movement blocking mechanism 18 is retracted into the carriage portion 9, so that both the first movement blocking mechanism 17 and the second movement blocking mechanism 18 are in the unlocked state. The mounting portion 10 is allowed to move from the top of the carriage portion 9 to the bathtub 2 side.

As shown in FIG. 8, the carriage portion 9 is a pair of rail members 9a facing in parallel in the left-right direction as a second delivery member for passing the mounting portion 10 between the transport vehicle 3 side and the bathtub 2 side. To be equipped with. The distance between the pair of rail members 9a in the front-rear direction is such that the pair of rail members 7a of the mounting portion 7 which is the first and third delivery members and the pair of stepped portions (rail portions) of the bogie fixing portion 5. It corresponds to each facing interval of 5d.

The mounting unit 10 can be transferred between the transport vehicle 3 side and the bathtub 2 side by the first to third transfer members, and the mounting unit 10 safely reciprocates between the carriage unit 9 and the moving mechanism 6. be able to.

The carriage fixing portion 5 and the first movement blocking mechanism portion 17 are formed symmetrically in the left-right direction in a plan view, whereby the left and right side walls of the bathtub 2 are formed as described later with reference to FIGS. 9A and 9B. In either case, the carriage fixing portion 5 can be attached to the bathtub 2.

As shown in FIG. 5, the groove portion 5c of the bogie fixing portion 5 has a first groove portion 5c1 linear in the front-rear direction and an R-shaped second groove portion 5c1 on both sides in the front-rear direction of the first groove portion 5c1. It consists of 5c2. Further, the engaging end portion 15b of the engaging member 15 of the carriage portion 9 corresponds to the linear first engaging end portion 15b1 corresponding to the first groove portion 5c1 and the second groove portion 5c2. It is R-shaped and consists of a first engaging end portion 15b1 and a second engaging end portion 15b2 on both sides.

Since both the first groove portion 5c1 and the first engaging end portion 15b1 are linear, when the first engaging end portion 15b1 engages with the first groove portion 5c1, the transport vehicle 3 uses the bathtub 2 Positioned parallel to the outer surface of the.

That is, the engaging member 15 of the carriage fixing portion 5 and the carriage portion 9 provides a positioning means for positioning the transport vehicle 3 at a specific position with respect to the bathtub 2 when the mounting portion 10 is moved to the bathtub 2 for bathing. Constitute.

By this positioning means, the transport vehicle 3 is positioned at the specific position with respect to the bathtub 2. This specific position is a position where the carriage portion 9 of the transport vehicle 3 is connected and fixed to the bathtub 2.

The positioning means can position the connecting position between the carriage portion 9 of the transport vehicle 3 and the bathtub 2 and connect and fix them, and can fix the carriage portion 9 to the bathtub 2 at the specific position. To configure.

Here, as shown in FIG. 9A, the carriage portion 9 is formed on the central cross section C1 of the mounting portion 10 (in this embodiment, it corresponds to the midline surface of the bather mounted on the mounting portion 10 in a plan view) and the bathroom floor surface. A vertical plane is symmetrically formed as a reference plane 9c1 or a perpendicular line passing through one end of a carriage portion 9 close to one end of a side wall of the bathtub 2 as a reference line 9c2 in a state of being positioned at the specific position. ..

Therefore, even if the carriage fixing portion 5 is provided at one end of either the left or right side wall of the bathtub 2, it is not necessary to rearrange the positioning means, and only the operation pedal 14 is rearranged to the carriage fixing portion 5 of the bathtub 2. The carriage portion 9 of the transport vehicle 3 can be positioned and connected and fixed.

As a result, various troublesome position adjustment work for positioning is not required, and it is not necessary to individually manufacture and sell bathing devices of models such as right specification and left specification, and it is possible to provide an inexpensive bathing device. .. In addition, one model of bathing device can support various layouts in the bathroom.

In this case, the reference line 9c2 is parallel to the direction in which the mounting portion 10 is moved in the bathtub 2 along the straight track by the first to third delivery members. Further, the mounting portion 10 is mounted on the carriage portion 9 so that its center line C2 (corresponding to the midline of the bather mounted on the mounting portion 10 in a plan view) is perpendicular to the reference line 9c2. As a result, as compared with the rotary configuration in which the mounting portion 10 is rotated and moved into the bathtub 2, the carriage portion 9 is placed on the same straight track on the carriage portion 9 and in the bathtub 2 from either the left or right side of the bathtub 2. The mounting unit 10 can be moved along the shortest distance, and the burden of moving assistance can be reduced.

Further, the bather can be moved into the bathtub 2 from either the left or right side of the bathtub 2 without changing the direction of the bathtub 2 while keeping the direction of moving the bather, and the bather's fear when the mounting unit 10 is moved. The feeling can be reduced.

Further, as compared with the bathing device of the model in which the carriage portion 9 is not fixed to the bathtub 2, the carriage portion 9 is reliably positioned on the bathtub 2 and is connected and fixed by the connecting mechanism, so that the mounting portion 10 is being reciprocated. It is possible to prevent an accident in which the carriage portion 9 moves carelessly and the mounting portion 10 falls from the carriage portion 9 or the bathtub 2.

The bogie portion 9 includes a pair of first frame members 11a that face each other in parallel in the front-rear direction of the bogie portion 9, a pair of second frame members 11b that face each other in parallel in the left-right direction of the bogie portion 9, and the first. A wheel 12 at each end of the frame member 11a in the front-rear direction and a rail member 9a (second delivery member) on the second frame member 11b are provided.

Here, in the front-rear direction of the trolley portion 9, the front side of the bather mounted on the mounting portion 10 on the trolley portion 9 is the front direction of the trolley portion 9, and the trolley portion 9 is mounted on the mounting portion 10 on the trolley portion 9. The back side of the bather is the rear direction of the carriage portion 9. The left-right direction of the carriage portion 9 is a direction orthogonal to the front-rear direction of the carriage portion 9. Further, the front-rear direction and the left-right direction of the trolley portion 9 are independent of the front-rear direction and the left-right direction of the tub 2, but in FIG. 9A, the front-rear left-right direction of the trolley portion 9 and the front-back left-right direction of the tub 2 are one. I am doing it.

Then, between the pair of first frame members 11a facing each other in the left-right direction, first spaces S1 are formed on both sides in the front-rear direction so that the bathing assistant can easily step in to perform the bathing assistance work of the bather. In addition, the bathing assistant can step on the pair of second frame members 11b between the pair of second frame members 11b so that the mounting portion 10 can be easily moved in the direction of the bathtub 2. Space S2 is formed.

Of the pair of first spaces S1, the space S1'in the front direction can be used for storing the lower leg support portion 10c of the mounting portion 10. As a result, the space S1'in the front direction is vacant as a stepping space, so that the bathing assistant can step into the space S1'in the front direction to assist the bather in transferring, and the work load is reduced. As shown, it can also be used as a foot space when the bather stands up.

The second space S2 is a wide space with a depth that extends beyond the center of the carriage portion 9 in the left-right direction to the bathtub 2 side. Therefore, when the bathing assistant fixes the transport vehicle 3 to the bathtub 2 and then moves the mounting unit 10 from the second delivery member of the trolley unit 9 to the bathtub 2 side, the bathing assistant moves the trolley unit 9 to the bathtub 2. The mounting unit 10 can be moved by stepping into the second space S2. As a result, the bathing assistant reduces the burden of assisting work of transferring the bather to the bathtub 2 side together with the mounting portion 10, and reduces the risk of injuring the lower back or the like during the work.

In FIG. 9A, the carriage fixing portion 5 is fixed to one side wall of the bathtub 2, but since the carriage portion 9 is symmetrical in the front-rear and left-right directions, the carriage fixing portion 5 is attached to the bathtub 2 as shown in FIG. 9B. The carriage portion 9 can be fixed to the other side wall of the bathtub 2. As described above, since the carriage portion 9 can be connected and fixed to the bathtub 2 regardless of which side of the left or right side wall of the bathtub 2 is attached to the carriage fixing portion 5, various layouts of the bathtub 2 can be supported.

With reference to FIGS. 10A to 10C, the mounting portion 10 is located at a different position in the movement direction of the lock member 17a of the first movement blocking mechanism portion 17 of the carriage fixing portion 5, or the second movement blocking mechanism portion 18. It has three first to third engaging portions that can be engaged with the locking member 18b. Here, the first engaging portion is the engaging portion 10d on the lower surface of the mounting portion 10, the second engaging portion is the engaging hole portion 10e on the lower portion of the mounting portion 10, and the third engaging portion. The portion is an engaging hole portion 10f at the lower part of the mounting portion 10. The shapes of the first to third engaging portions are not limited to the above, and may be recesses, holes, or the like, and the combination thereof is arbitrary.

By having these engaging portions 10d, 10e, and 10f, the mounting portion 10 is different in the moving direction so that the mounting portion 10 does not accidentally fall from the carriage portion 9 or the mounting portion 7. It can be locked in a fourth predetermined position. Here, the first predetermined position is the position where the mounting portion 10 is locked by the lock member 18b and the engaging portion 10d on the carriage portion 9, and the second predetermined position is the position where the mounting portion 10 is locked on the carriage portion 9. Is the position where is locked by the lock member 18b and the engagement hole 10e. Further, the third predetermined position is a position where the mounting portion 10 is locked by the lock member 17a and the engaging portion 10d on the mounting portion 7, and the fourth predetermined position is the mounting portion on the mounting portion 7. 10 is a position where the lock member 17a and the engaging hole 10f are locked.

When the mounting portion 10 moves on the carriage portion 9, when the lock member 18b of the second movement blocking mechanism portion 18 engages with the engaging portion 10d, the mounting portion 10 moves from the first predetermined position. Is blocked (first locked state). Further, when the lock member 18b of the second movement blocking mechanism portion 18 engages with the engaging hole portion 10e, the mounting portion 10 is prevented from moving from the second predetermined position (second locked state).

In this way, the second movement blocking mechanism portion 18 first determines that the lock member 18b protrudes from the carriage portion 9 and engages with the engaging portion 10d of the mounting portion 10 so that the mounting portion 10 falls from the carriage portion 9. Stop in the locked state. However, due to an erroneous operation, the lock member 18b cannot engage with the engaging portion 10d of the mounting portion 10, so that the mounting portion 10 moves in the dropout direction by a distance from the first predetermined position to the second predetermined position. However, the lock member 18b enters the engaging hole 10e by the urging force of the spring member 18d. As a result, the movement of the mounting portion 10 can be prevented in the second locked state, so that the mounting portion 10 can be prevented from falling from the carriage portion 9.

The mounting unit 10 can be easily moved from the second predetermined position to the first predetermined position. In this case, the chamfered upper surface 18e of the lock member 18b comes into contact with the end surface of the engagement hole 10e, and the lock member 18b is rotated clockwise around the shaft 18c to retract from the engagement hole 10e. Therefore, since the lock member 18b and the engaging hole portion 10e do not interfere with each other, the mounting portion 10 can be easily returned from the second predetermined position to the first predetermined position.

Further, when the mounting unit 7 is in the second predetermined position, the center of gravity of the mounting unit 7 and the bather mounted on the mounting unit 7 is biased and is in an unstable state, so that the mounting unit 7 is in an unstable state as described above. By returning to the first predetermined position, the posture of the mounting unit 7 and the bather can be stabilized and the safety of the bather can be ensured.

When the mounting portion 10 moves on the mounting portion 7, when the lock member 17a of the first movement blocking mechanism portion 17 engages with the engaging portion 10d, the mounting portion 10 moves from the third predetermined position. It is blocked (third locked state). Further, when the lock member 17a of the first movement blocking mechanism portion 17 engages with the engaging hole portion 10f, the mounting portion 10 is prevented from moving from the fourth predetermined position (fourth locked state).

In this way, the first movement blocking mechanism portion 17 prevents the locking member 17a from protruding from the carriage fixing portion 5 and engaging with the engaging portion 10d of the mounting portion 10 so that the mounting portion 10 falls from the mounting portion 7. Stop in the third locked state. However, due to an erroneous operation, the lock member 17a cannot engage with the engaging portion 10d of the mounting portion 10, so that the mounting portion 10 moves in the dropout direction by a distance from the third predetermined position to the fourth predetermined position. However, the lock member 17a enters the engaging hole portion 10f by the urging force of the spring member 17c. As a result, the movement of the mounting portion 10 can be prevented by entering a fourth locked state, so that the mounting portion 10 can be prevented from falling from the mounting portion 7.

The mounting unit 10 can be easily moved from the fourth predetermined position to the third predetermined position. In this case, since the lock member 17a can be rotated counterclockwise by the spring member 17c about the shaft 17d, the lock member 17a comes into contact with the end surface of the engaging hole portion 10f, and the lock member 17a rotates counterclockwise. It is rotated to retract from the engaging hole 10f. Therefore, since the lock member 17a and the engaging hole portion 10f do not interfere with each other, the mounting portion 10 can be easily returned from the fourth predetermined position to the third predetermined position.

Further, when the mounting unit 7 is in the fourth predetermined position, the center of gravity of the mounting unit 7 and the bather mounted on the mounting unit 7 is biased and is in an unstable state, so that the mounting unit 7 is in an unstable state as described above. By returning to the third predetermined position, the posture of the mounting unit 7 and the bather can be stabilized and the safety of the bather can be ensured.

The center of gravity of the second movement blocking mechanism portion 18 is set to be located on the shaft 18c. As a result, even when the trolley portion 9 passes over an uneven floor surface and receives an impact force in the vertical direction, it is possible to prevent the second moving mechanism portion 18 from rotating about the shaft 18c. Therefore, it is possible to prevent the lock member 18b from rotating clockwise to disengage the lock member 18b from the engaging portion 10d.

The position of the center of gravity of the second movement blocking mechanism portion 18 is not limited to the above, and may be, for example, on the unlocking member 18a side. In this case, since a force that tends to rotate counterclockwise around the shaft 18c acts on the second movement blocking mechanism portion 18, the spring member 18d that urges the lock member 18b clockwise Even if the locking member 18b is deteriorated and its urging force is weakened, it is possible to prevent the locking member 18b from rotating clockwise to disengage the locking member 18b from the engaging portion 10d.

With reference to FIGS. 11 to 14, the mounting portion 10 of the transport vehicle 3 is provided with an operating lever 20 on the back side thereof as shown in FIG. The operating lever 20 is urged downward, and the lower end thereof is pivotally supported by a shaft 21a as shown in FIGS. 12 and 13. One end side 22a of the doglegged lock member 22 is also pivotally supported on the shaft 21a. The central portion of the lock member 22 is pivotally supported by a shaft 21b. The other end side 22b of the lock member 22 can be engaged in the notch recess 23 on the side surface of the rail member 9a of the carriage portion 9.

When the operating lever 20 is not operated, as shown in FIG. 12, the lock member 22 is engaged in the notch recess 23 on the side surface of the rail member 9a, and the mounting portion 10 is fixed on the bogie portion 9 and the rail. The movement on the member 9a is blocked (locked state).

When the operating lever 20 is operated upward, as shown in FIG. 13, the lock member 22 rotates counterclockwise around the shaft 21b and comes off from the notch recess 23 on the side surface of the rail member 9a, so that the mounting portion 10 is removed. It can be moved from the trolley portion 9 to the bathtub 2 side (unlocked state).

FIG. 14 is a cross-sectional view of the carriage portion 9 and the bathtub 2 viewed from the front in the front direction. The carriage portion 9 has a symmetrical operation pedal 14 that is operated when the carriage portion 9 is separated from the bathtub 2. The operation pedal 14 is provided with pedals 14a and 14b. One end side of the engaging member 15 is pivotally supported by a shaft 15c, and the other end side is an engaging end portion 15b. The operation pedal 14 is connected to the engaging member 15 by a mechanism including a plurality of rotating shafts 24a to 24f and a plurality of connecting bars 25a to 25d. Since the pedal 14b on the left side is not used for the operation of separating the carriage portion 9 from the bathtub 2, it cannot be stepped on by the range of motion limiting means (not shown). Since the operation pedal 14 has a symmetrical shape, the operation pedal 14 attached to the rear side in FIG. 9A may be rearranged to the front side when the carriage portion 9 is connected to the other end side of the bathtub. Further, the operation pedal is not limited to the above-mentioned shape and configuration, and the shape, configuration, mounting position, etc. that do not need to be rearranged may be appropriately changed.

The carriage portion 9 has a second movement blocking mechanism portion 18 including a locking member 18a and an unlocking member 18b. The carriage fixing portion 5 of the bathtub 2 is provided with a first movement blocking mechanism portion 17 including a locking member 17a and an unlocking member 17b.

In order to allow the bather to take a bath in the bathtub 2, the transport vehicle is brought close to the bathtub 2 and the carriage portion 9 is connected and fixed to the bathtub 2 by the carriage fixing portion 5. When the trolley portion 9 is connected to the bathtub 2, the locks of the first movement blocking mechanism portion 17 and the second movement blocking mechanism portion 18 are released, so that the mounting portion 10 is moved to the bathtub 2 side from above the trolley portion 9. .. After the movement is completed, the trolley portion 9 may be separated from the bathtub 2 by depressing the pedal 14a, if necessary. Then, FIG. 14 shows a state immediately before the carriage portion 9 is close to the bathtub 2 side and the lock by the first movement blocking mechanism portion 17 and the second movement blocking mechanism portion 18 is released because the bathing is completed. There is.

When the carriage portion 9 is connected to the bathtub 2, the mounting portion 10 on the mounting portion 7 of the bathtub 2 is unlocked by the first movement blocking mechanism portion 17 and the second movement blocking mechanism portion 18, and the bathtub 2 is released. Since it becomes possible to move from the bathtub portion 9 to the carriage portion 9, the mounting portion 10 is moved from the bathtub 2 side to the carriage portion 9 side.

When this movement is completed, the operation pedal 14a is depressed to separate the trolley portion 9 from the bathtub 2 side, and the mounting portion 10 is locked on the trolley portion 9 by the second movement blocking mechanism portion 18, so that the bathing assistant can take a bath. The finished bather can be transported.
