Description

  TECHNICAL FIELD The present invention relates to a technique suitable for use in a swinging open / close type bathing apparatus capable of bathing a physically handicapped person or an elderly person in a sitting position.

  Conventionally, as a bathing apparatus for bathing a bather seated in a wheelchair or the like in a sitting position, there is a swinging open / close type bathing apparatus. This swinging open / close bathing device has a fixed bathtub opened on one side, a swing bathtub having an opening corresponding to the opening of the fixed bathtub and swinging in the vertical direction, and two on the bottom surface of the fixed bathtub. And a rail provided in parallel.

  When bathing with the above-described conventional swing opening / closing type bathing apparatus, first, the bather is seated in a wheelchair that can separate the chair portion and the carriage (chair lower portion). Rollers are attached to both sides of the chair portion. On the other hand, the swinging bathtub is stored under the fixed bathtub and the opening of the fixed bathtub is opened. Next, the wheelchair is moved, and the chair part is moved into the fixed bathtub while running the roller of the chair part on the rail on the fixed bathtub. And after moving a chair part to the back of a fixed bathtub, a chair part is cut off from a trolley and only a trolley is pulled out. Next, the rocking bathtub is rocked upward. Thereby, the opening of a fixed bathtub and the opening of a rocking bathtub are connected, a fixed bathtub and a rocking bathtub are continued in a watertight state, and the bathtub which can store hot water is formed. Next, the bather is bathed in hot water in the bathtub. When the bather has finished bathing, drain the hot water from the bathtub. And after hot water draining is completed, the swinging bathtub is swung to the opening side of the fixed bathtub, and the swinging bathtub is stored under the fixed bathtub to open the opening of the fixed bathtub. Next, the wheelchair carriage is placed under the fixed bathtub, and the chair portion and the carriage in the fixed bathtub are combined. Then, pull out the wheelchair while running the chair roller on the rail.

By the way, the rail described above is configured to tilt with the swinging motion of the swinging bathtub. If demonstrating it concretely, the rotating shaft is provided in the base end part (end part of the back | inner side of a fixed bathtub) of a rail, and the rail is vertically rotatable. Moreover, the rolling member which rolls on the inner surface of a rocking bathtub is provided in the front-end | tip part (end part of the opening side of a fixed bathtub) of a rail. The rail is pushed up and tilted by the swinging tub through the rolling member as the swinging bathtub swings upward, and is lowered as the swinging bathtub swings toward the opening side of the fixed bathtub. According to such a structure, when the rocking tub is opened, the rails are arranged in a horizontal state, and the bather sitting on the chair portion on the rails is in an upright posture. On the other hand, when the rocking tub is closed, the rail is arranged in an inclined state, and the bather seated on the chair portion on the rail is in a posture that falls backward (see, for example, Patent Documents 1 to 3). .
Japanese Patent No. 3474554 Japanese Patent No. 3535126 JP 2003-190245 A

  However, in the above-described conventional swinging open / close bathing device, when the swinging bathtub is closed, the chair portion in the fixed bathtub is in a free state in which the chair can move along the rail. Also, the blow molded part of the chair part is easy to float due to buoyancy. For this reason, there is a problem that when the bather is bathed with hot water in the bathtub, the chair portion moves upward (front end side) along the inclined rail due to the buoyancy of the chair portion itself.

  In addition, in the above-described conventional swinging open / close bathing device, the chair portion in the bathtub can slide on the rail even when the rail is not lowered to the position where it can be combined with the carriage, so that after the bathing is completed When combining a chair part with a trolley | bogie, the position of a chair part and a trolley | bogie may shift | deviate and it may not be united well.

  In the present invention, the above-described conventional problems are taken into consideration, and the movement of the chair portion during bathing due to buoyancy can be prevented, and the rail is lowered to a position where it can be combined with the lower portion of the chair (cart). It is an object of the present invention to provide a swinging open / close bathing device capable of preventing unsatisfactory combination of the chair portion and the chair lower portion due to the absence of the chair portion.

  The swing opening / closing bathing apparatus according to the present invention has a fixed bathtub having an opening on one side, an opening corresponding to the opening of the fixed bathtub, and a swing fulcrum located near the upper end of the opening portion. A swinging bathtub that is swingable in a vertical direction, and the opening is connected to the opening of the fixed bathtub so that the swinging bathtub forms a bathtub that can be filled with water. Is swung between a closed state that is continuous in a watertight state and an open state that is housed under the fixed bathtub and opens the opening of the fixed bathtub. A rail that extends in the depth direction of the fixed bathtub and supports the chair portion of the wheelchair and travels the chair portion in the depth direction is provided, and the rail swings the swing bathtub in the closed state. The tip is raised and tilted according to A swinging open / close bathing apparatus in which the tip is lowered and the inclination is reduced as the tank swings in the open state direction, and the chair moves along the rail when the rail is tilted. When the rail comes to a position where it can be combined with the lower portion of the chair, a lock mechanism is provided that allows the chair portion to move along the rail.

  With such a feature, the swing tub is housed in the lower side of the fixed tub so that one side of the fixed tub is opened. At this time, the rocking tub is swung in the open state direction until the rail comes to a position where it can be combined with the lower part of the chair. Thereby, a lock mechanism will be in the lock release state which accept | permits the movement of the chair part along a rail. Next, the chair portion is moved along the rail to the back side of the fixed bathtub while the bather is seated on the chair portion of the wheelchair from the open opening of the fixed bathtub. Thereby, a bather is put in a fixed bathtub with a sitting posture. At this time, the bather is moved from the back side of the bather into the fixed bathtub so as to move the bather backward. Next, after the chair part put in the fixed bathtub is separated from the chair lower part, the swinging bathtub is swung in the closed state. As a result, the tip of the rail is raised and the rail is tilted, and the chair portion supported by the rail is also pushed up and tilted. As the chair portion is tilted in this manner, the bather sitting on the chair portion is placed in a posture that is tilted backward (a supine posture). The rocking bathtub is swung in the closed direction until the opening is connected to the opening of the fixed bathtub. Thereby, the bathtub which can be filled with water which consists of a rocking bathtub and a fixed bathtub is formed. Hot water is put into this bathtub and bathers are bathed. At this time, since the rail is inclined, the lock mechanism is in a locked state that restricts the movement of the chair portion along the rail, and the movement of the chair portion toward the rail front end is restricted.

  After bathing, first drain the hot water from the bathtub. And after the hot water in a bathtub is completely lose | eliminated, a rocking bathtub is rock | fluctuated in an open state direction, and one side of a fixed bathtub is opened. At this time, the rocking tub is swung in the open state direction until the rail comes to a position where it can be combined with the lower part of the chair. Thereby, a lock mechanism will be in a lock release state, and the movement of the chair part along a rail is accept | permitted. In a state where the rail is not lowered to the position where it can be combined with the lower portion of the chair, the lock mechanism remains in the locked state, and the movement of the chair portion along the rail is restricted. After swinging the rocking tub until the rail comes to the position where it can be combined with the lower part of the chair, the chair part in the fixed tub is united with the lower part of the chair, and then the wheelchair is moved out of the fixed tub along the rail. . Thereby, the bather after bathing is taken out of a fixed bathtub with a sitting posture.

  Further, in the swing opening / closing type bathing apparatus according to the present invention, the locking mechanism includes a locking member provided on the chair portion side, a locked member provided on the rail side, and the locked member. A biasing member that biases the locked member so that a part of the rail is disposed at a locking position where the locking member is in contact with the locking member. When a contact portion that comes into contact with the bottom surface of the fixed bathtub is provided at a position where it can be combined with the lower portion of the chair, and the contact portion comes into contact with the bottom surface of the fixed bathtub, the locked member It is preferable that it is the structure which moves to the non-locking position which does not contact | abut the said locking member.

  As a result, when the rail is tilted without being lowered to the position where it can be combined with the lower portion of the chair, the locked member is disposed at the locking position by the biasing force of the biasing member. Thereby, even if a chair part tries to move along a rail, the locking member provided in the chair part side is contact | abutted to the to-be-latched member provided in the rail side, and the movement of a chair part is controlled. On the other hand, when the rail is lowered to the position where it can be combined with the lower portion of the chair, the abutting portion comes into contact with the bottom surface of the fixed bathtub, the locked member moves, and the locked member is arranged at the non-locking position. As a result, the locking member provided on the chair portion side does not contact the locked member provided on the rail side, and the movement of the chair portion is allowed.

  According to the swing opening and closing type bathing apparatus according to the present invention, even if buoyancy acts on the chair portion in the bathtub filled with hot water, the chair portion moves along the rail by the lock mechanism when the swing bathtub is in a closed state. Therefore, the movement of the chair part during bathing can be prevented. In addition, when the rail is not lowered to the position where it can be combined with the lower part of the chair, the lock mechanism restricts the movement of the chair along the rail, and when the rail is lowered to the position where it can be combined with the lower part of the chair. Since the lock mechanism is released and the movement of the chair portion along the rail is allowed, it is possible to prevent the union failure between the chair portion and the chair lower portion.

  On the other hand, as shown in FIG. 6, the swinging tub 31 is housed in the lower side of the fixed tub 30, so that one side of the fixed tub 30 is opened. At this time, the rocking bathtub 31 is swung in the open state until the rail 52a reaches a position where the rail 52a can be combined with the carriage 10. As a result, as shown in FIG. 14, the second contact portion 121 c of the lock mechanism 120 is brought into contact with the bottom portion 36 of the fixed bathtub 30, and the first contact portion 121 b is brought into contact with the detachment prevention convex portion 113. The lock mechanism 120 is placed in a non-locking position where it does not come into contact, and the lock mechanism 120 is unlocked. When the lock mechanism 120 is in the unlocked state, the movement of the chair portion 120 along the rail 52 a is allowed, and the above-described wheelchair 1 can be brought into the fixed bathtub 30.

  In the state described above, the wheelchair 1 on which the bather is placed is moved to the opening side of the open fixed tub 30 and set to the carry-in position so that the back of the bather is directed to the opening side of the fixed tub 30. . At this time, the end of the square pipe 16 of the wheelchair 1 is fitted between the guides 71 and 71 to align the wheelchair 1 with respect to the swinging open / close bath apparatus 2.

  Thereafter, as shown in FIG. 7, the wheelchair 1 is moved from the back side of the bather into the fixed bathtub 30 so as to move the bather backward, and is pushed into the back side of the fixed bathtub 30. Then, the fixed position of the plate member 13b is set by the convex portion of the lock member 82b and fixed, and the carriage 10 of the wheelchair 1 is fixed by the wheelchair fixing means 82 to be in a fixed state (loading state). Thereby, a bather is put in the fixed bathtub 30 with a sitting posture. At this time, the roller 17 a of the chair part frame 17 is rolled on the rail 52 a so that the chair part 12 can be supported by the chair support part 52. Further, the tip of the safety rod 107 a comes into contact with the safety contact portion 108 of the guide rail tip 71, and the safety rod 107 a moves in the approach direction of the wheelchair 1. As a result, the lock member 107b, which has been in the upright locked state, is rotated and tilted clockwise in FIGS. 6 to 8 to be released from the pin attaching / detaching pedal 106b.

  Next, the chair portion 12 placed in the fixed bathtub 30 is separated from the cart 10. Specifically, the pin attaching / detaching pedal 106b is stepped on to move the attaching / detaching pin 105 downward to release the fixing state of the attaching / detaching plate 102. The chair portion 12 is pushed to the right side in the drawing to be separated from the carriage 10, and the roller 17a rolls on the rail 52a which is in a substantially horizontal position, so that the chair portion 12 is moved along the rail 52a. As shown in FIG. 8, the bather is accommodated in the bathtubs 30 and 31. At this time, the pressing roller 103 is offset from the position immediately above the corresponding roller 101 in the fixed state in the moving direction of the chair portion 12 and is spaced upward from the corresponding roller 101 as shown in FIG. It is in a state of swinging to the upper right.

  Next, after detecting that the chair part 12 is placed at a predetermined position by the chair part detection switch 121, the cylinder 90 is driven by the control means, and the rocking bathtub 31 is closed with the rocking fulcrum 91 as the center. Swing in the state direction. As the rocking bathtub 31 rocks in the closed state, the roller 52c rolls on the bottom 38 of the rocking bathtub 31, and is supported on the bottom 38 of the rocking bathtub 31 via the roller 52c and the tilting support 52b. The tip ends of the rails 52a and 52a are lifted so as to be pushed up, and the rails 52a and 52a (the chair support portion 52) are rotated (tilted) around the rotation fulcrum 51. Thereby, the rails 52a and 52a (chair support 52) are tilted, and the chair 12 placed on the rails 52a and 52a (chair support 52) is tilted in the same manner as the rails 52a and 52a. The seated bather is in a supine posture that is tilted backwards. Further, as shown in FIG. 15, the rails 52 a and 52 a are tilted so that the second contact portion 121 c of the lock mechanism 120 is separated from the bottom portion 36 of the fixed bathtub 30. As a result, the locked portion 121 is rotated by the biasing force of the biasing member 122, the first contact portion 121b is disposed at the locking position where it contacts the slip-off preventing convex portion 113, and the lock mechanism 120 is in the locked state. Become.

The rocking bathtub 31 is swung in the closed state until the rocking position detecting means 124b detects that the rocking bathtub 31 is closed. Thereby, the swinging bathtub 31 is swung to a position where the opening is connected to the opening of the fixed bathtub 30, the upper end of the swinging bathtub 31 becomes substantially horizontal, and the swinging bathtub 31 and the fixed bathtub 30 are in a watertight state. It becomes the closed state which continued in the. By being in the closed state, the bathtubs 30 and 31 that can be filled with hot water are formed.
Here, the packing 40a as the watertight means 40 of the bent portions 30a and 31a and the receiving member 40b thereof are brought into close contact with each other, thereby bringing the fixed bathtub 30 and the rocking bathtub 31 into a watertight state during bathing.

  Next, hot water is supplied from the tank 60 into the bathtubs 30 and 31, hot water is applied to the bathtubs 30 and 31, and the bather is bathed. At this time, the swinging open / close bath device 2 detects the amount of hot water with the water level sensors 122a, 122b, 123a, 123b and detects the temperature of the hot water with a hot water temperature sensor (not shown). At this time, as described above, the rail 52a is tilted and the lock mechanism 120 is in a locked state, so that the movement of the chair portion 12 toward the tip of the rail 52a is restricted.

  When bathing is completed, the drain plug opening / closing pedal 47 is stepped on, and the drain plug 44 closing the drain hole 45 is pushed upward to drain the water. When the water level sensor 122a detects that the hot water in the bathtubs 30 and 31 has been drained, the control means drives the cylinder 90 to swing the swinging bathtub 31 in the open state and Open the side. As the swinging tub 31 swings in the open state, the roller 52c rolls on the bottom 38 of the swinging tub 31, and is supported on the bottom 38 of the swinging tub 31 via the roller 52c and the tilting support 52b. The tips of the rails 52a and 52a are lowered, the rails 52a and 52a (the chair support portion 52) are rotated (tilted) around the rotation fulcrum 51, and the inclination of the rails 52a and 52a is reduced. Thereby, the chair part 12 supported on the rails 52a and 52a (chair support part 52) becomes horizontal, the body of the bather in the supine posture is raised, and the bather is in the sitting position. At this time, the rocking bathtub 31 is swung in the open state until the rail 52a comes to a position where it can be combined with the carriage 10. Accordingly, as shown in FIG. 14, the second contact portion 121 c is brought into contact with the bottom surface 36 of the fixed bathtub 30, and the locked member 121 rotates against the urging force of the urging member 122, The one abutting portion 121b moves to a non-locking position where it does not abut against the slip-off preventing convex portion 113, and the lock mechanism 120 enters the unlocked state.

  Next, after the chair portion 12 is combined with the carriage 10, the wheelchair 1 is pulled out from the swinging open / close bath device 2, and the bather is moved out of the fixed bathtub 30. Thereby, the bather after bathing is taken out of the rocking | fluctuating open / close type bathing apparatus 2 with a sitting posture. Specifically, the bather who gets up in the sitting position is moved forward along the rail 52 a together with the chair portion 12, and the attaching / detaching pin 105 is attached to the attaching / detaching hole 104 while the attaching / detaching plate 102 is pressed by the pressing roller 103 and the roller 101. Insert into and fix. In this state, the wheelchair release pedal 82c is depressed, the wheelchair 1 is unlocked, and the wheelchair 1 is moved forward (to the left in the figure), thereby contacting the safety contact portion 108 of the guide rail tip 71. When the safety rod 107 a is separated from the safety contact portion 108, the safety rod 107 a moves to the rear side (right direction) of the wheelchair 1 with respect to the carriage 10. As a result, the lock member 107b, which has been tilted and released, rotates counterclockwise in FIGS. 6 to 8 and is brought into a locked state in contact with the pin attaching / detaching pedal 106b. 10 and the chair part 12 are prevented from being inadvertently separated.

  Further, as described above, when the chair portion 12 is combined with the carriage 10 and the wheelchair 1 is moved, the rail 52a is lowered to the position where it can be combined with the carriage 10 as described above, and the lock mechanism 120 is unlocked. Therefore, the movement of the chair portion 12 toward the front end side of the rail 52a is allowed.

  According to the swinging open / close bathing apparatus 2 having the above-described configuration, the movement of the chair portion 12 along the rail 52a is restricted by the lock mechanism 120 when the swinging bathtub 31 is in the closed state. Even if buoyancy acts on the chair portion 12 due to hot water in the bathtubs 30 and 31, the movement of the chair portion 12 is restricted by the lock mechanism 120. Thereby, the chair part 12 can be prevented from being lifted during bathing. Further, when the rail 52a is not lowered to the position where it can be combined with the carriage 10, the movement of the chair portion 12 is restricted by the lock mechanism 120, and when the rail 52a is lowered to the position where it can be combined with the carriage 10. Since the lock mechanism 120 is released and the movement of the chair portion 12 is allowed, after the bathing, the swinging tub 31 is opened, but the rail 52a is lowered to a position where it can be combined with the carriage 10 although it is incomplete. If not, the movement of the chair portion 12 is restricted. As a result, it is possible to prevent the union failure between the chair portion 12 and the carriage 10 due to the rail 52a not being lowered to the position where the carriage 52 can be joined with the carriage 10.

  Moreover, according to the swinging open / close bathing apparatus 2 having the above-described configuration, the locking mechanism 120 includes a slip-off preventing convex portion 113 provided on the chair portion 12 side and a locked member 121 provided on the rail 52a side. And a biasing member 122 that biases the locked portion 121 so that the first abutting portion 121b of the locked member 121 is disposed at a locking position where the first contacting portion 121b abuts against the slip-off preventing convex portion 113. Composed of the configuration, the locked portion 121 is provided with a second contact portion 121c that contacts the bottom surface 36 of the fixed bathtub 30 when the rail 52a is lowered to the position where it can be combined with the carriage 10. When the second contact portion 121c is brought into contact with the bottom surface 36 of the fixed bathtub 30, the locked portion 121 is configured to move to a non-locking position where it does not come into contact with the slip-off preventing convex portion 113. To the position where the rail 52a can be combined with the carriage 10 If Gerare non is restricted movement of the chair unit 12, the movement of the seat part 12 is allowed when the rail 52a is lowered to a dockable position of the carriage 10. Thereby, the lock mechanism 120 having a simple configuration can be realized without using a sensor or the like.

  Further, according to the swinging open / close bath device 2 having the above-described configuration, when the bather in the sitting position is placed on the back, the bather remains on the chair portion 12, so that the body is securely held, Stability is maintained even during tilting. In addition, when taking a bath, the bather has the same posture as a general bath, and can take a comfortable bath. Further, in the swinging open / close bathing apparatus 2 in which the bather is tilted as shown in FIG. 8, the load applied from the chair support 52 to the bottom 38 of the swinging bathtub 31 can be reduced by the buoyancy of the float F.
