The trolley | bogie fixed part 5 comprises the 3rd delivery member which delivers the mounting part 10 between the bathtub 2 side and the conveyance vehicle 3 side by comprising the level | step-difference part 5d as a rail part.

  A first movement blocking mechanism for blocking movement of the mounting portion 10 in the lateral direction on the moving mechanism 6 except when the carriage portion 9 is connected and fixed to the bathtub 2 by the carriage fixing portion 5 in the carriage fixing portion 5 A mechanism unit 17 is provided.

  As shown in FIGS. 6A and 6B, the first movement preventing mechanism unit 17 is integrally formed with the lower end side of the lock member 17a whose upper end can project and retract from the carriage fixing unit 5 and the other end side The lock release member 17b (an integral body with the lock member 17a) supported pivotally by the shaft 17d and a spring member 17c biasing the members in the clockwise direction (lock direction) are provided. The lock release member 17b is a bogie The lock member 17 a can be protruded or retracted from the through hole 5 e formed in the groove portion 5 c of the fixed portion 5, and the lock member 17 a can be protruded or retracted from the through hole 5 f formed in the main body portion 5 b of the carriage fixed portion 5.

  When the engaging end 15b of the engaging member 15 does not enter the groove 5c of the carriage fixing portion 5, the locking member 17a projects from the carriage fixing portion 5 by the biasing of the spring member 17c, and the unlocking member 17b , And protrudes from the groove portion 5c. In this projecting state, the first movement preventing mechanism 17 prevents movement of the mounting unit 10 between the side of the carrier 3 and the side of the bathtub 2.

  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 biasing force of the spring member 17c and rotates in the counterclockwise direction. Withdraws into the portion 5 c and with this, the lock member 17 a withdraws into the carriage fixing portion 5. As a result, the first movement preventing mechanism unit 17 permits movement of the mounting unit 10 between the side of the carrier 3 and the side of the bathtub 2.

  The carriage portion 9 of the carrier 3 is provided with a second movement preventing mechanism unit 18. The second movement blocking mechanism 18 blocks movement of the mounting unit 10 on the carriage unit 9 (locked state) except when the carriage unit 9 is connected and fixed to the bathtub 2 by the carriage fixing unit 5. .

It is biased in the counterclockwise direction by the (biasing member). When the locking member 18b is projected on the lower surface of the mounting portion 10 by the urging of the spring member 18d and engaged with the engaging portion 10d (first engaging portion) on the lower surface side, the mounting portion 10 is locked by the locking member 18b. The movement on the carriage 9 is blocked (locked) and the carriage 9 is prevented from falling off.

  In addition, as shown in FIG. 7, the second movement preventing mechanism 18 has a plurality of members along the width direction of the engaging member 15 at intervals at which the bather can not operate the second movement preventing mechanism 18 simultaneously with one hand. (2 in FIG. 7) are provided. By this, the following effects can be obtained. That is, when the carriage portion 9 is erroneously connected to the bathtub 2 from an oblique direction, both the second movement preventing mechanism portions 18 start to engage with the carriage fixing portion 5 temporally before and after. Therefore, in the situation where the diagonal connection has been completed, the second movement preventing mechanism unit 18 which has first started the connection to the carriage fixing unit 5 may perform the above-mentioned unlocking, but the trolley fixing unit is later The second movement preventing mechanism 18 that has started to be connected to 5 is not unlocked as described above. Thereby, the erroneous release of the lock of the second movement prevention mechanism unit 18 at the time of the diagonal connection of the carriage unit 9 is prevented.

  In addition, since the second movement preventing mechanism 18 is provided as described above, all the second movement preventing mechanism 18 are simultaneously used by a bather's misuse when the second movement preventing mechanism 18 is not connected to the bathtub 2. The lock release 18 is prevented from being released, and the mounting portion 10 is prevented from falling off the carriage portion 9.

  When the carriage portion 9 is pushed in the direction of the bathtub 2, the engagement end 15b of the engagement member 15 protruding from the side surface of the carriage portion 9 rises on the inclined portion 5a of the carriage fixing portion 5 against the bias of the spring member. Then, it enters into the groove portion 5c of the carriage fixing portion 5 by the urging of the spring member. When the engagement 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 preventing mechanism 17 moves the mounting portion 10 from the carrier 3 side to the bathtub 2 side. Since the lock member 18b of the second movement prevention mechanism 18 retracts into the carriage 9 while being allowed, both the first movement prevention mechanism 17 and the second movement prevention mechanism 18 are unlocked. The mounting unit 10 is allowed to move from the top of the carriage 9 to the bathtub 2 side.

  As shown in FIG. 8, the carriage portion 9 is a pair of rail members 9 a facing in parallel in the left-right direction as a second delivery member for delivering the mounting portion 10 between the carrier 3 side and the bathtub 2 side. Equipped with The distance between the pair of rail members 9a in the front-rear direction is the pair of rail members 7a of the mounting portion 7 as the first and third transfer members and the pair of step portions (rail portions) of the carriage fixing portion 5 It corresponds to each opposing interval of 5 d.

  The loading portion 10 can be delivered between the carriage 3 side and the bathtub 2 side by the first to third delivery members, and the loading portion 10 safely reciprocates between the carriage portion 9 and the moving mechanism 6 be able to.

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

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

  Since the first groove portion 5c1 and the first engagement end 15b1 are both linear, when the first engagement end 15b1 is engaged with the first groove portion 5c1, the transport vehicle 3 is moved to the bathtub 2 Parallel to the outer surface of the

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

  The carrier 3 is positioned at the specific position with respect to the bathtub 2 by this positioning means. The specific position is a position where the carriage portion 9 of the carrier 3 is connected and fixed to the bathtub 2.

  The positioning means can position the connecting position of the carriage 9 of the carrier 3 and the bath 2 and connect and fix them, and a connecting mechanism which can fix the carriage 9 to the bath 2 at the specific position. Configure

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

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

  As a result, various troublesome position adjustment operations for the positioning become unnecessary, and it is not necessary to individually manufacture and sell bathing devices of the right specification and left specification, and an inexpensive bathing device can be provided. . In addition, it is possible to cope with various in-bath layouts with one type of bathing apparatus.

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

  In addition, with the direction to move the bather into the bathtub 2, it is possible to move the inside of the mounting unit 10 from the left or right of the bathtub 2 without turning the mounting unit 10, and the fear of the bather when moving the mounting unit 10. You can reduce the feeling.

  Further, as compared with the type of bathing apparatus in which the carriage 9 is not fixed to the bathtub 2, the carriage 9 is reliably positioned on the bathtub 2 and connected and fixed by the connection mechanism. Thus, it is possible to prevent an accident in which the mounting portion 10 falls from the trolley portion 9 or the bathtub 2 due to the trolley portion 9 moving carelessly.

  The carriage portion 9 includes a pair of first frame members 11a opposed in parallel in the front-rear direction of the carriage portion 9, a pair of second frame members 11b opposed in parallel in the left-right direction of the carriage portion 9, and a 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, the front side of the bather who is mounted on the mounting unit 10 on the carriage unit 9 is the front direction of the carriage unit 9 in the front-rear direction of the carriage unit 9 and is mounted on the mounting unit 10 on the carriage unit 9 The back side of the bather is the back direction of the carriage 9. The left-right direction of the carriage portion 9 is a direction orthogonal to the front-rear direction of the carriage portion 9. Although the longitudinal direction and the lateral direction of the carriage portion 9 are independent of the longitudinal direction and the lateral direction of the bathtub 2, in FIG. 9A, the longitudinal direction and the lateral direction of the carriage portion 9 and the longitudinal direction and the lateral direction of the bathtub 2 are one. I do.

  And between the opposing of the left-right direction of a pair of 1st frame members 11a, the 1st space S1 which a bathing assistant can easily step in in order to perform bathing assistance work of a bather is formed in the front-back direction both sides Also, between the facing in the front-rear direction of the pair of second frame members 11b, the bathing assistant can step in 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 forward space S1 ′ can be used to store the lower thigh support 10c of the mounting portion 10. As a result, since the forward space S1 'is freed as a stepping space, the bathing assistant can step into the forward space S1' to perform the transfer work of the bather, and the work load is reduced, and FIG. As shown, it can also be used as a foot space for the bather's standing movement.

  The second space S2 is a wide space having a depth extending beyond the center of the carriage 9 in the left-right direction to the bathtub 2 side. Therefore, when the bathing assistant fixes the transport vehicle 3 to the bath 2 and then moves the mounting portion 10 from the second delivery member of the carriage 9 to the bathtub 2 side, the bathing assistant takes the position of the carriage 9 Stepping in the second space S2 allows the loading unit 10 to be moved. As a result, the burden of assistance work for transferring a bather to the bathtub 2 side together with the loading unit 10 is reduced, and the risk of hurting the waist or the like in the work is reduced.

  The carriage fixing portion 5 is fixed to one side wall of the bathtub 2 in FIG. 9A, but since the carriage portion 9 is symmetrical in the front, rear, left and right, as shown in FIG. The carriage portion 9 can be fixed to the other side wall of the bath 2 by fixing it to the other side wall of the tub 2. As described above, even if the carriage fixing portion 5 is attached to either side of the left and right side walls of the bathtub 2, the carriage portion 9 can be connected and fixed to the bathtub 2, so that various layouts of the bathtub 2 can be accommodated.

  Referring to FIGS. 10A to 10C, the mounting unit 10 is located at a different position in the moving direction of the lock member 17a of the first movement preventing mechanism 17 or the second movement preventing mechanism 18 of the carriage fixing unit 5. It has three first to third engagement portions engageable with the lock member 18b. Here, the first engagement portion is the engagement portion 10d of the lower surface of the mounting portion 10, and the second engagement portion is the engagement hole portion 10e at the lower portion of the mounting portion 10, and the third engagement portion The portion is an engagement hole 10 f in the lower portion of the mounting portion 10. In addition, the shape of a 1st-3rd engaging part is not limited above, A recessed part, a hole part, etc. may be sufficient, and the combination is arbitrary.

  The mounting portion 10 has the engaging portions 10d, 10e and 10f, so that the mounting portion 10 does not fall from the carriage portion 9 or the mounting portion 7 by mistake, the first to It can be locked in the fourth predetermined position. Here, the first predetermined position is a position where the mounting portion 10 is locked by the locking member 18 b and the engaging portion 10 d on the carriage portion 9, and the second predetermined position is the mounting portion 10 on the carriage portion 9. Is a position locked by the locking member 18b and the engagement hole 10e. Further, the third predetermined position is a position where the mounting portion 10 is locked on the mounting portion 7 by the locking member 17 a and the engaging portion 10 d, and the fourth predetermined position is the mounting portion on the mounting portion 7 10 is a position where it is locked by the locking member 17a and the engagement hole 10f.

  When the mounting unit 10 moves on the carriage unit 9, when the lock member 18 b of the second movement prevention mechanism unit 18 engages with the engaging unit 10 d, the mounting unit 10 moves from the first predetermined position. To be blocked (first locked state). In addition, when the lock member 18b of the second movement prevention mechanism 18 engages with the engagement hole 10e, the movement of the mounting unit 10 from the second predetermined position is blocked (a second locked state).

  As described above, in the second movement preventing mechanism unit 18, the locking member 18b protrudes from the carriage unit 9 and engages with the engaging unit 10d of the mounting unit 10 to cause the mounting unit 10 to fall from the carriage unit 9 Block in the locked state. However, the locking member 18b can not engage with the engaging portion 10d of the mounting portion 10 due to an erroneous operation, so the mounting portion 10 moves in the dismounting direction by the distance of the second predetermined position from the first predetermined position. Even in this case, the lock member 18b enters the engagement hole 10e by the biasing force of the spring member 18d. As a result, the movement of the mounting unit 10 can be prevented in the second locked state, so that the falling of the mounting unit 10 from the carriage unit 9 can be prevented.

  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 contacts the end face of the engagement hole 10e, and the lock member 18b is rotated clockwise about the shaft 18c to retract from the engagement hole 10e. Therefore, since the lock member 18b and the engagement hole 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, at the second predetermined position of the mounting portion 7, the center of gravity of the mounting portion 7 and the bather mounted thereon is biased to be in an unstable state. By returning to the first predetermined position, the mounting portion 7 and the bather's posture can be stabilized to secure the bather's safety.

  When the mounting unit 10 moves on the mounting unit 7, when the lock member 17 a of the first movement prevention mechanism unit 17 engages with the engaging unit 10 d, the mounting unit 10 moves from the third predetermined position. Being blocked (third locked state). In addition, when the lock member 17a of the first movement prevention mechanism 17 engages with the engagement hole 10f, the movement of the mounting unit 10 from the fourth predetermined position is blocked (fourth lock state).

  As described above, in the first movement preventing mechanism unit 17, the locking member 17 a protrudes from the carriage fixing unit 5 and engages with the engaging unit 10 d of the mounting unit 10 so that the mounting unit 10 falls from the mounting unit 7. Block in the third lock state. However, the locking member 17a can not engage with the engaging portion 10d of the mounting portion 10 due to an erroneous operation, so the mounting portion 10 moves in the dismounting direction by the distance from the third predetermined position to the fourth predetermined position. Even in this case, the lock member 17a enters the engagement hole 10f by the biasing force of the spring member 17c. As a result, the movement of the mounting unit 10 can be prevented in the fourth locked state, so that the falling of the mounting unit 10 from the mounting unit 7 can be prevented.

  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 around the shaft 17d by the spring member 17c, the lock member 17a is in contact with the end face of the engagement hole 10f, and the lock member 17a is rotated counterclockwise. And is retracted from the engagement hole 10f. Therefore, since the lock member 17a and the engagement hole 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, at the fourth predetermined position of the mounting portion 7, the center of gravity of the mounting portion 7 and the bather mounted thereon is biased to be in an unstable state, and thus the mounting portion 7 is as described above. By returning to the third predetermined position, the mounting portion 7 and the position of the bather can be stabilized to ensure the safety of the bather.

  The center of gravity of the second movement prevention mechanism 18 is set to be located at the axis 18 c. As a result, even when the carriage portion 9 passes an uneven floor surface and receives an impact force in the vertical direction, for example, the second moving mechanism unit 18 is prevented from rotating about the shaft 18c. Since this can be performed, it is possible to prevent the lock member 18b from rotating clockwise and disengaging the lock member 18b from the engagement portion 10d.

  The position of the center of gravity of the second movement prevention mechanism 18 is not limited to the above, and may be on the side of the unlocking member 18a, for example. In this case, since the second movement preventing mechanism 18 is acting to rotate counterclockwise around the shaft 18c, the spring member 18d biasing the lock member 18b clockwise is It is possible to prevent the locking member 18b from rotating clockwise and disengaging the engagement between the locking member 18b and the engaging portion 10d even if the biasing force is deteriorated due to deterioration.

  With reference to FIGS. 11 to 14, the mounting portion 10 of the carrier 3 is provided with an operation lever 20 on the back side as shown in FIG. 11. The control lever 20 is biased downward, and its lower end is pivotally supported by a shaft 21a as shown in FIGS. One end 22a of the lock member 22 in the shape of "く" is also pivotally supported by the shaft 21a. The lock member 22 is pivotally supported at its central portion by a shaft 21b. The other end 22 b of the lock member 22 is engageable with the notch recess 23 on the side surface of the rail member 9 a of the carriage 9.

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

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

  FIG. 14 is a cross-sectional view of the carriage 9 and the bathtub 2 as viewed from the front, and the carriage 9 has a symmetrical operation pedal 14 operated to separate the carriage 9 from the bathtub 2. The operation pedal 14 is provided with pedals 14a and 14b. One end of the engagement member 15 is pivotally supported by a shaft 15c, and the other end is an engagement end 15b. The operation pedal 14 is connected to the engagement member 15 by a mechanism including a plurality of rotation shafts 24a to 24f and a plurality of connection bars 25a to 25d. The pedal 14b on the left side is not used for the operation of separating the carriage 9 from the bathtub 2, so that it can not be stepped on by the movable range limiting means (not shown). Since the operation pedal 14 has a symmetrical shape, when the carriage 9 is connected to the other end of the bathtub, the operation pedal 14 attached to the rear side in FIG. 9A may be rearranged on the front side. In addition, the operation pedal is not limited to the above-described shape or configuration, and the shape, the configuration, the attachment position, and the like which do not need to be rearranged may be appropriately changed.

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

  In order to allow the bather to bathe in the bath tub 2, the transport vehicle is brought close to the bath tub 2 and the bogie section 9 is connected and fixed to the bath tub 2 by the bogie fixing section 5. When the carriage 9 is connected to the bathtub 2, the lock of the first movement prevention mechanism 17 and the second movement prevention mechanism 18 is released, so the loading unit 10 is moved from the carriage 9 to the bathtub 2 side. . After the movement is completed, the carriage portion 9 may be separated from the bathtub 2 by stepping on the pedal 14a, if necessary. And FIG. 14 shows the state immediately before the lock | rock by the 1st movement prevention mechanism part 17 and the 2nd movement prevention mechanism part 18 is cancelled | released, since the trolley | bogie part 9 adjoins to the bathtub 2 side, There is.

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

  When this movement is completed, the operation pedal 14a is depressed to separate the carriage 9 from the bathtub 2 side, the mounting unit 10 is locked on the carriage 9 by the second movement prevention mechanism 18 and the bathing assistant takes a bath The finished bather can be transported.
