  Hereinafter, a bathing apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  With reference to FIG. 1 thru | or FIG. 8, the bathing apparatus 1 is provided with the bathtub 2 and the conveyance vehicle 3. FIG. In this specification, the longitudinal direction of the bathtub 2 is called the front-back direction, and the direction orthogonal to this is called the left-right direction.

As shown in FIG. 1, the bathtub 2 is surrounded by a front wall, a rear wall, and both side walls so that a bathing recess is formed therein, and has an outer shape that is rectangular in plan view. Edges of both corners on the front wall side on the side constitute a first seating portion 4 on which a bather who performs bathing directly can sit. A carriage fixing portion 5 for connecting and fixing (docking) the transport vehicle 3 to the bathtub 2 is provided at the upper end portion on the other end side in the longitudinal direction of one side wall of the bathtub 2. The carriage fixing portion 5 is provided at the upper end portion of one side wall of the both side walls of the bathtub 2, but is not limited thereto, and may be provided within a predetermined range above the outer surface of the side wall of the bathtub 2. Good. This “within a predetermined range” means that when a bather who has been transported by a transport vehicle takes a bath directly without using a transport vehicle, the carriage fixing part may interfere with the bather or his / her bathing assistant, or may protrude. This is within the range where there is no risk of injury from the fixed trolley.

  As shown in FIG. 4, since the cart fixing part 5 does not protrude outward from the lower foot of the outer side surface of the side wall of the bathtub 2, the cart fixing part 5 is a bather or a bathing assistant when bathing directly. There is no possibility that the bather or the bathing assistant will be injured due to the fact that the bogie fixing part 5 comes into contact with the body.

  In addition, since the carriage fixing part 5 is located higher than the bathroom floor surface, the bathroom floor surface can be easily cleaned, the bathroom can be kept clean, and the mechanical impression of the entire apparatus disposed in the bathroom is softened and homely. You can give bathers the impression of a bathtub.

  As shown in FIG. 1, the bathtub 2 is provided with a moving mechanism 6 that moves (lifts and lowers) the bather in the bathtub 2. The moving mechanism 6 includes a placement unit 7 and a link mechanism 8.

  As shown in FIGS. 1 and 3, the transport vehicle 3 includes a cart unit 9 and a mounting unit 10 that can be separated from the cart unit 9. The carriage unit 9 includes a plurality of frame members 11, a plurality of wheels 12, an operation pedal 14, and the like.

  The cart portion 9 is provided with an engaging member 15 that engages with the cart fixing portion 5 on the bathtub 2 side.

  As shown in FIG. 8, the engaging member 15 is configured by a frame frame 15 a made of a pipe material in a rectangular frame shape in plan view, and one end side is pivotally supported and the other end side is engaged with the carriage fixing portion 5. The other end side including the engagement end portion 15b is biased downward by a spring member with the end portion 15b serving as a rotation center.

  As shown in FIG. 1, the mounting portion 10 includes a seat portion 10a on which a bather can sit, a backrest portion 10b on which the bather can sit back, and a crus support portion 10c that supports the lower leg of the bather.

  The bathtub 2 is provided with a cover 16 for covering the moving mechanism 6 so as to be opened and closed. In FIG. 1, the cover 16 is shown in an open state and does not cover the moving mechanism 6.

  As shown in FIG. 4, the mounting portion 7 on the bathtub 2 side includes a pair of rail portions 7 a that face in parallel in the left-right direction along the rear wall of the bathtub 2, and is located between the bathtub 2 and the transport vehicle 3. The 1st delivery member which delivers mounting part 10 is constituted.

  The cart fixing portion 5 includes an inclined portion 5a, a main body portion 5b, and a groove portion 5c between the outer peripheral edge of the inclined portion 5a and the inner peripheral edge of the main body portion 5b. The groove portion 5 c has a shape and a groove width that can be engaged with the engaging end 15 b of the engaging member 15. 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 contacts the body of the bather or bathing assistant. In addition, the engagement end portion 15b can be smoothly fitted into the groove portion 5c.

  As shown in FIG. 3, the carriage fixing portion 5 has a pair of step portions 5 d parallel to each other in the left-right direction on both sides in the front-rear direction as rail portions. The spacing between the pair of stepped portions 5d corresponds to the spacing between the pair of rail portions 7a included in the mounting portion 7. The cart fixing portion 5 includes a step portion 5d as a rail portion, thereby constituting a third delivery member that delivers the mounting portion 10 between the bathtub 2 side and the transport vehicle 3 side.

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

  As shown in FIGS. 6A and 6B, the first movement prevention mechanism 17 includes a lock member 17a whose upper end protrudes and retracts from the carriage fixing portion 5, and a lower end of the lock member 17a that is integral with the other end. An unlocking member 17b supported by a shaft 17d (integrated with the locking member 17a) and a spring member 17c for urging them in a clockwise direction (locking direction) are provided. The lock member 17a can be protruded or retracted from the through hole 5f formed in the main body portion 5b of the carriage fixing portion 5, and can be protruded or retracted from the through hole 5e formed in the groove portion 5c of the fixing portion 5.

  When the engaging end 15b of the engaging member 15 does not enter the groove portion 5c of the cart fixing portion 5, the lock member 17a protrudes from the cart fixing portion 5 by the bias of the spring member 17c, and the lock releasing member 17b is , Protruding from the groove portion 5c. In this protruding state, the first movement prevention mechanism 17 prevents the movement of the mounting part 10 between the transport vehicle 3 side and the bathtub 2 side.

  When the engagement end portion 15b of the engagement member 15 enters the groove portion 5c of the carriage fixing portion 5, the lock release member 17b is pushed against the urging force of the spring member 17c, and rotates counterclockwise. The lock member 17a is retracted into the carriage fixing portion 5 together with retreating into the portion 5c. As a result, the first movement prevention mechanism unit 17 allows the mounting unit 10 to move between the transport vehicle 3 side and the bathtub 2 side.

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

  The second movement blocking mechanism 18 includes a lock release member 18a that can rotate integrally around a shaft 18c provided on the engagement member 15, and a lock member 18b that is integral with the lock release member 18b. The urging member is urged counterclockwise. When the locking member 18b protrudes on the lower surface of the mounting portion 10 by the bias 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 moved by the locking member 18b to the carriage portion. It is blocked (locked) from moving on 9, and is prevented from falling off the carriage unit 9.

  In addition, as shown in FIG. 7, a plurality of second movement prevention mechanisms 18 are provided along the width direction of the engagement member 15 at intervals at which the bather cannot simultaneously operate the second movement prevention mechanisms 18 with one hand. (Two in FIG. 7) are provided. Thereby, the following effect is acquired. That is, when the cart unit 9 is erroneously coupled to the bathtub 2 from an oblique direction, both the second movement prevention mechanism units 18 and 18 start to engage with the cart fixing unit 5 before and after time. Therefore, in the situation where the diagonal connection is finished, the second movement prevention mechanism unit 18 that has started the connection to the cart fixing unit 5 may perform the above-described unlocking, but the cart fixing unit later. The second movement prevention mechanism unit 18 that has started the connection to 5 is not unlocked as described above. This prevents erroneous unlocking of the second movement blocking mechanism 18 when the cart unit 9 is obliquely connected.

  In addition, since the second movement prevention mechanism 18 is provided as described above, when not connected to the bathtub 2, all the second movement prevention mechanisms 18, at the same time, due to misuse by the bather, 18 is prevented from being unlocked, and the mounting portion 10 is prevented from falling off the carriage unit 9.

  When the carriage 9 is pushed in the bathtub 2 direction, the engagement end 15b of the engagement member 15 protruding from the side of the carriage 9 rises on the inclined portion 5a of the carriage fixing part 5 against the bias of the spring member. Therefore, it enters the groove portion 5c of the carriage fixing portion 5 by the bias 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 prevention mechanism portion 17 moves the mounting portion 10 from the transport vehicle 3 side to the bathtub 2 side. While permitting, since the lock member 18b of the second movement blocking mechanism 18 is retracted into the carriage 9, the first movement blocking mechanism 17 and the second movement blocking mechanism 18 are both unlocked. The mounting portion 10 is allowed to move from the top of the cart portion 9 to the bathtub 2 side.

  As shown in FIG. 8, the carriage unit 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 unit 10 between the transport vehicle 3 side and the bathtub 2 side. Is provided. 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 serving as the first and third delivery members described above and the pair of step portions (rail portions) of the carriage fixing portion 5 This corresponds to the facing distance of 5d.

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

  The cart fixing portion 5 and the first movement prevention mechanism portion 17 are formed symmetrically in the left-right direction in plan view, and thereby, as will be described later with reference to FIGS. 9A and 9B, In any case, the cart fixing part 5 can be attached to the bathtub 2.

  As shown in FIG. 5, the groove portion 5c of the carriage fixing portion 5 includes a first groove portion 5c1 that is linear in the front-rear direction and R-shaped second groove portions on both sides in the front-rear direction of the first groove portion 5c1. 5c2. 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 consists of a second engagement end portion 15b2 on both sides of the first engagement end portion 15b1.

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

  That is, the engagement member 15 of the carriage fixing portion 5 and the carriage portion 9 is provided with 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. Configure.

  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 unit 9 of the transport vehicle 3 is connected and fixed to the bathtub 2.

  The positioning means can position the connection position between the carriage unit 9 of the transport vehicle 3 and the bathtub 2 to connect and fix them, and the connection mechanism can fix the carriage unit 9 to the bathtub 2 at the specific position. Configure.

  Here, as shown to FIG. 9A, the trolley | bogie part 9 is in the center cross section C1 (this example corresponds to the midline surface of the bather mounted on the mounting part 10 by planar view) of the mounting part 10, and a bathroom floor surface. A vertical plane is defined as a reference plane 9c1, or a perpendicular line passing through one end of the carriage 9 adjacent to one end of the side wall of the bathtub 2 in a state of being positioned at the specific position as a reference line 9c2. .

  Therefore, even if the cart fixing part 5 is provided at one of the left and right side walls of the bathtub 2, it is not necessary to change the positioning means, and only a minor work of changing the operation pedal 14 can be performed on the cart fixing part 5 of the bathtub 2. The carriage unit 9 of the transport vehicle 3 can be positioned and connected and fixed.

  As a result, various troublesome position adjustment operations for positioning are not required, and there is no need to individually manufacture and sell bathing apparatuses of the right specification and left specifications, so that an inexpensive bathing apparatus can be provided. . In addition, one type 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 linear track by the first to third delivery members. Moreover, the mounting part 10 is mounted on the cart part 9 so that the center line C2 (which coincides with the midline of the bather mounted on the mounting part 10 in plan view) is perpendicular to the reference line 9c2. Thereby, compared with the rotary structure which rotates the mounting part 10 and moves in the bathtub 2, the cart part 9 is made into the same linear track on the cart part 9 and the bathtub 2 from either the right or left of the bathtub 2. The mounting part 10 can be moved along the shortest distance along, and the movement assistance burden can be reduced.

  Moreover, it can move in the bathtub 2 without changing the direction of the mounting part 10 from either the left or right of the bathtub 2 in the direction in which the bather is moved in the bathtub 2, and the fear of the bather when the mounting part 10 moves. The feeling can be reduced.

  Further, compared to a bathing device of a model in which the carriage unit 9 is not fixed to the bathtub 2, the carriage unit 9 is reliably positioned on the bathtub 2 and is connected and fixed by the connecting mechanism. Thus, it is possible to prevent an accident in which the carriage unit 9 moves carelessly and the mounting unit 10 falls from the carriage unit 9 or the bathtub 2.

  The cart unit 9 includes a pair of first frame members 11 a that face in parallel in the front-rear direction of the cart unit 9, a pair of second frame members 11 b that face in parallel in the left-right direction of the cart unit 9, and a first Wheels 12 at the front and rear ends of the frame member 11a and rail members 9a (second delivery members) on the second frame member 11b are provided.

  Here, in the front-rear direction of the carriage part 9, the front side of the bather mounted on the mounting part 10 on the carriage part 9 is the front direction of the carriage part 9, and the carriage part 9 is mounted on the mounting part 10 on the carriage part 9. The back side of the bather is the rear direction of the carriage unit 9. The left-right direction of the carriage unit 9 is a direction orthogonal to the front-rear direction of the carriage unit 9. Further, the front-rear direction and the left-right direction of the carriage unit 9 are independent from the front-rear direction and the left-right direction of the bathtub 2, but in FIG. I'm doing it.

  Between the pair of first frame members 11a facing in the left-right direction, a first space S1 is formed on both sides in the front-rear direction so that the bathing assistant can easily step in to perform bathing assistance for the bather. In addition, a second bathing assistant can step in between the pair of second frame members 11b in the front-rear direction so that the mounting assistant 10 can easily move the mounting portion 10 toward the bathtub 2. A space S2 is formed.

  Of the pair of first spaces S1, the forward space S1 ′ can be used to store the lower leg support portion 10c of the mounting portion 10. As a result, the forward space S1 ′ is vacated as a stepping space, so that the bathing assistant can step into the forward space S1 ′ and perform the bather's transfer assistance work, and the work load is reduced. As shown, it can be used as a foot space when the bather stands up.

  The second space S2 is a wide space having a depth that extends beyond the center in the left-right direction of the carriage unit 9 and reaches the bathtub 2 side. Therefore, when the bathing assistant operates the fixing of the transport vehicle 3 to the bathtub 2 and then moves the mounting portion 10 from the second delivery member of the carriage portion 9 to the bathtub 2 side, The mounting part 10 can be moved by stepping into the second space S2. Thereby, the burden of the assistance work which a bathing assistant transfers a bather to the bathtub 2 side with the mounting part 10 is reduced, and the risk of damaging a waist etc. by the said work is reduced.

  In FIG. 9A, the cart fixing portion 5 is fixed to one side wall of the bathtub 2, but the cart portion 9 is symmetrical in the front-rear and left-right directions, so that the cart fixing portion 5 is connected to the bathtub 2 as shown in FIG. 9B. It can fix to the other side wall of this, and the trolley | bogie part 9 can be fixed to the other side wall of the bathtub 2. FIG. In this way, the carriage fixing part 5 can be connected and fixed to the bathtub 2 regardless of which side of the right and left side walls of the bathtub 2 is attached.

  With reference to FIG. 10 thru | or FIG. 18, the moving mechanism 6 and the cover 16 by the side of the bathtub 2 are demonstrated. FIG. 10 shows the bathtub 2 when the transport vehicle bathing is performed, and FIG. 11 shows the bathtub 2 when the bathing is performed directly.

  The bathtub 2 is formed in a rectangular shape in plan view, and has, as described above, the first seating portion 4 on which a bather who takes a bath directly can sit, at one end portion in the longitudinal direction. The moving mechanism 6 includes a placement portion 7 and a link mechanism 8 that are covered with a cover 16 when the bather takes a bath directly.

  Since the moving mechanism 6 is not provided outside the bathtub 2 and is directly covered with a cover 16, the appearance of the bathtub 2 is close to the appearance of the bathtub 2 used in a general home. Yes. Therefore, a bather who takes a bath directly can sit and bathe in both the first seating portion 4 and the second seating portion (described later) in a bathing atmosphere similar to that of a general home. By this, the person who has paralysis in the right half or the left half of the body can put the body of the person who has paralysis on the first seating part 4 or the second seating part and is not paralyzed Since the body can be assisted by an assistant, safe bathing can be realized.

  Also, a bather who takes a bath directly sits in the first seat 4 and moves into the bathtub 2 or sits in the second seat without being disturbed by the moving mechanism 6. Or you can take a bath directly.

  As shown in FIGS. 12 and 13, the cover 16 covers a first protection portion 16 a that covers and protects the placement portion 7 of the moving mechanism 6, and a second cover that covers and protects the link mechanism 8 of the moving mechanism 6. And a protective portion 16b.

  The first protection portion 16a has a flat plate shape that covers the other end of the bathtub 2 so that a bather who takes a bath directly can sit. The first protection portion 16a is provided with a gripping portion 16c that can be gripped when a bather who performs bathing directly moves into the bathtub 2. The first protection portion 16a constitutes the second seating portion on which a bather who takes a bath directly with the moving mechanism 6 covered is seated.

  The second protection portion 16 b is erected downward with respect to the first protection portion 16 a so as to face the bathtub 2, and a bather who directly takes a bath can sit back in the bathtub 2. The second protective portion 16b is provided with a fixing hole 16d to which a fixing member such as a belt for fixing a bather who directly takes a bath in the bathtub 2 can be attached. The fixing holes 16d are provided with at least a pair of right and left, and if necessary, two or more pairs of fixing holes 16d.

  The cover 16 is slidably fixed to the bathtub 2 or the mounting portion 7 (tub side) by a cover floating prevention mechanism 19 shown in FIG. 14 so that the cover 16 can be prevented from floating from the bathtub 2. .

  In FIG. 14, the first protective portion 16a of the cover 16 is shown in cross section. The connection part 19a which has a horizontal L shape is provided in the left-right direction pair by the 1st protection part 16a lower part. In addition, a pair of connecting portions 19b having an L shape is provided on the mounting portion 7 in a pair in the left-right direction. This connection part 19b is not restricted to being provided in the mounting part 7, and may be provided in the bathtub 2. FIG. The cover 16 is slidably attached in the left-right direction.

  When the cover 16 is slid in the left-right direction, one connecting portion 19a is positioned below one connecting portion 19b and is opposed in the vertical direction, and the other connecting portion 19a is opposed to the other connecting portion 19b in the vertical direction. do not do.

  When the cover 16 is slid to the other in the left-right direction, the other connecting portion 19a and the other connecting portion 19b face each other in the vertical direction in the same manner as described above.

  Thereby, even if the buoyancy by the hot water in the bathtub 2 acts on the cover 16, it is prevented that the connection part 19b floats by the connection part 19a. Therefore, even if the cover 16 receives buoyancy due to hot water, the cover 16 can be prevented from floating from the bathtub 2.

  The cover 16 is attached to the bathtub 2 so as to be rotatable in the front-rear direction via the rotary shaft 25. Specifically, the cover 16 can be rotated rearward of the bathtub 2 without being removed from the bathtub 2. Yes. Thereby, when bathing directly, the cover 16 can be installed so as to cover the moving mechanism 6 by rotating in the forward direction of the bathtub 2, and when bathing the transport vehicle, the cover 16 is placed behind the bathtub 2. Tilt it in the direction so that it does not get in the way of bathing on the transport vehicle.

  As illustrated in FIG. 15, the moving mechanism 6 of the bathtub 2 includes a placement portion 7 and a link mechanism 8. As described above, the mounting portion 7 includes the pair of rail portions 7a that guide the mounting portion 10 toward the bathtub 2 as a first delivery member.

  The link mechanism 8 includes first to third arm portions 8a to 8c, first and second rotating shafts 8d and 8e, first to third connection pins (only the second connection pin 8f is shown), Have The first and second rotating shafts 8 d and 8 e are provided below the side wall of the recess of the bathtub 2. In the side wall of the bathtub 2, a motor and the like for rotating the first and second rotary shafts 8d and 8e are incorporated. One end of the first arm portion 8a is provided so as to be rotatable about the first rotation shaft 8d. The other end of the first arm portion 8a is attached to the placement portion 7 by a first connecting pin. One end of the second arm portion 8b and one end of the third arm portion 8c are both provided to be rotatable about the second rotation shaft 8e. The other end of the second arm portion 8b is attached to the mounting portion 7 by a second connecting pin 8f. The other end of the third arm portion 8c is attached to the mounting portion 7 by a third connecting pin.

  16 to 18 show a state of the mounting portion 7 rotated by the link mechanism 8. When the first and second rotary shafts 8d and 8e rotate, the other ends of the first to third arm portions 8a to 8c rotate in an arc shape with the mounting portion 7 held horizontally. Specifically, the first to third arm portions 8a to 8c rotate counterclockwise by the rotation of the rotary shafts 8d and 8e, and are arranged in the vicinity of the other end of the bathtub 2 in the initial state. The mounting unit 7 (state shown in FIG. 16) is moved in the forward direction of the bathtub 2 and moved downward of the bathtub 2 (state shown in FIG. 17). Further, by rotating these rotary shafts 8d, 8e, the first to third arm portions 8a to 8c are rotated until they are substantially parallel to the bottom of the bathtub 2, so that the mounting portion 7 finally has the It is moved to the bottom (state of FIG. 18). Thus, when the carriage 7 is bathed by moving the placement unit 7, the bather can take a bath while sitting on the seat of the mounting unit 10 of the carriage 3.

  When direct bathing is performed, the placing portion 7 is rotated in an arc shape from the inside of the bathtub 2 to the other end of the bathtub 2 by the link mechanism 8, and the placing portion 7 is left in the bathtub 2 and directly. Since it does not obstruct bathing, the inside of the bathtub 2 can be used as widely as possible.

  Further, the mounting portion 7 is covered by the first protective portion 16 a of the cover 16, so that the mounting portion 7 can be made invisible from the outside. The protective portion 16a can be seated on the second protective portion 16a as a second seating portion.

  Further, the second protective portion 16b of the cover 16 can make the link mechanism 8 invisible, and a bather who takes a bath directly leans on the second protective portion 16b of the cover 16 in the bathtub 2. You can bathe comfortably.

  Furthermore, since the bather who directly takes a bath can stabilize the posture when he / she grips the grip 16c and moves to the bathtub 2, bathing can be performed safely.

  Furthermore, since the bather who takes a bath directly by a fixing member such as a belt attached to the mounting hole 16d of the second protective portion 16b of the cover 16 can be fixed in a safe posture in the bathtub 2, the bath directly It is possible to prevent a submergence accident in the bathtub 2 of the bather who performs.

  Furthermore, the cover lifting prevention mechanism 19 prevents the cover 16 from being lifted by the influence of buoyancy from the bath water in the bathtub 2 even if the cover 16 is made of a relatively lightweight material made of resin. can do. Furthermore, by simply rotating the cover 16 in the front-rear direction of the bathtub 2, it is possible to easily switch between direct bathing and transport vehicle bathing, and it is not necessary to take a place when the cover 16 is removed.

  Referring to FIG. 19A to FIG. 19C, the mounting portion 10 is located at different positions in the movement direction of the lock member 17 a of the first movement prevention mechanism portion 17 of the carriage fixing portion 5 or the second movement prevention mechanism portion 18. It has three first to third engagement portions that can be engaged with the lock member 18b. Here, the first engagement portion is the engagement portion 10d on 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 10f at the bottom of the mounting portion 10. In addition, the shape of the first to third engagement portions is not limited to the above, and may be a recess, a hole, or the like, and the combination thereof is arbitrary.

  The mounting portion 10 has these engaging portions 10d, 10e, and 10f, so that the mounting portion 10 does not accidentally fall from the carriage portion 9 or the placement portion 7 so that the first to different movement directions are different. It can be locked at the fourth predetermined position. Here, the first predetermined position is a position on the carriage unit 9 where the mounting part 10 is locked by the locking member 18b and the engaging part 10d, and the second predetermined position is the mounting part 10 on the carriage part 9. Is a position locked by the locking member 18b and the engaging hole 10e. The third predetermined position is a position where the mounting portion 10 is locked by the locking 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. Reference numeral 10 denotes a position locked by the lock member 17a and the engagement hole 10f.

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

  As described above, the second movement prevention mechanism portion 18 is configured such that the locking member 18b protrudes from the cart portion 9 and engages with the engaging portion 10d of the mounting portion 10 so that the mounting portion 10 falls from the cart portion 9. Stop in the locked state. However, due to an erroneous operation, the lock member 18b cannot be engaged with the engaging portion 10d of the mounting portion 10, and therefore the mounting portion 10 moves in the drop-off direction by a distance from the first predetermined position to the second predetermined position. Even so, the lock member 18b enters the engagement hole 10e by the biasing force of the spring member 18d. Thereby, since the movement of the mounting part 10 can be prevented in the second locked state, the falling of the mounting part 10 from the cart part 9 can be prevented.

  The mounting portion 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 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.

  In addition, when the mounting portion 7 is in the second predetermined position, the mounting portion 7 and the center of gravity of the bather mounted thereon are biased and are in an unstable state. By returning to the first predetermined position, the posture of the mounting portion 7 and the bather can be stabilized and the safety of the bather can be ensured.

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

  As described above, the first movement prevention mechanism 17 is configured such that the locking member 17a protrudes from the carriage fixing portion 5 and engages 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 be engaged with the engaging portion 10d of the mounting portion 10, and therefore the mounting portion 10 moves in the drop-off direction by a distance from the third predetermined position to the fourth predetermined position. Even so, the lock member 17a enters the engagement hole 10f by the urging force of the spring member 17c. Thereby, since the movement of the mounting part 10 can be prevented in the fourth locked state, the falling of the mounting part 10 from the mounting part 7 can be prevented.

  The mounting portion 10 can be easily moved from the fourth predetermined position to the third predetermined position. In this case, the lock member 17a can be rotated counterclockwise about the shaft 17d by the spring member 17c. Therefore, the lock member 17a comes into contact with the end face of the engagement hole 10f, and the lock member 17a is counterclockwise. And retracted from the engagement hole 10f. Accordingly, the lock member 17a and the engagement hole portion 10f do not interfere with each other, so that the mounting portion 10 can be easily returned from the fourth predetermined position to the third predetermined position.

  In addition, when the mounting portion 7 is in the fourth predetermined position, the mounting portion 7 and the center of gravity of the bather mounted thereon are biased and are in an unstable state. By returning to the third predetermined position, the posture of the mounting portion 7 and the bather can be stabilized and the safety of the bather can be ensured.

  In the second movement prevention mechanism 18, the center of gravity is set so as to be positioned on the shaft 18c. This prevents the second moving mechanism 18 from rotating about the shaft 18c even when the cart 9 passes over an uneven floor and receives an impact force in the vertical direction. Therefore, 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 lock release member 18a side, for example. In this case, since the force that rotates counterclockwise about the shaft 18c acts on the second movement blocking mechanism 18, the spring member 18d that urges the lock member 18b clockwise is provided. Even if the biasing force is weakened due to deterioration, it is possible to prevent the lock member 18b from rotating clockwise and disengaging the lock member 18b from the engagement portion 10d.

  Referring to FIG. 20 to FIG. 23, the mounting portion 10 of the transport vehicle 3 includes an operation lever 20 on the back side thereof as shown in FIG.

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

  FIG. 23 is a cross-sectional view of the carriage unit 9 and the bathtub 2 as viewed from the front in the front. The carriage unit 9 has a symmetrical operation pedal 14 that is operated when the carriage unit 9 is separated from the bathtub 2. The operation pedal 14 includes 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 left pedal 14b is not used for the operation of separating the carriage unit 9 from the bathtub 2, it cannot be stepped on by a not-shown movable range limiting means. In addition, since the operation pedal 14 is a left-right symmetric shape, when connecting the trolley | bogie part 9 to the other end side of a bathtub, you may rearrange the operation pedal 14 attached to the rear side in FIG. 9A to the front side. Further, the operation pedal is not limited to the shape and configuration described above, and the shape, configuration, attachment position, and the like that do not require recombination may be changed as appropriate.
