Description

The present invention relates to a bathtub that is not so complicated in structure and can be easily bathed while on a wheelchair.

In Japan, the number of people using wheelchairs is increasing in addition to those who are physically disabled due to illness or injury. In recent years, barrier-free has been promoted in public buildings and train stations, and elevators directly connected to platforms have been actively used. Moreover, in the home where there is a person using a wheelchair, the residence is made barrier-free, and a housing environment that is convenient for the person using the wheelchair without a step is being developed.

In this way, barrier-free is being promoted in each home, public building, etc., but in fact, a bathtub that can be put on a wheelchair is rarely seen. This is because bathing is a private matter, and the time and frequency of bathing vary from person to person, and the bathing time is not necessary for a long time. Therefore, it seems that bathing itself is not so important.

On the other hand, bathing is not just a private matter, but it is also an important public health issue for the sick, injured, and elderly, and it is unsanitary if the injured person does not bathe for days. On the other hand, injuries may be worsened or the recovery of injuries may be delayed until not worsened. Also, even if elderly people or injured people want to bathe, if they are unable to bathe on their own, they will miss the opportunity to bathe, resulting in an unsanitary state of not bathing for days. It was.

Meanwhile, bathtubs that do not require caregivers are being developed. For example, a side plate on one side of a bathtub is provided to be freely opened and closed by an air cylinder, a sealing material and a lock mechanism are provided on one side, and a guide groove for a wheelchair is provided on the inner surface of the side plate and the bottom plate. .

As a result, the wheelchair is placed on the bottom plate, and then the four side plates are erected and stopped by the respective locking brackets, so that the bathtub is completed and the wheelchair bathtub is easy to assemble.

Embodiment 1 of the present invention will be described below with reference to FIG.

FIG. 1 shows a wheelchair bathtub A (hereinafter simply referred to as “tub A”) according to Embodiment 1 of the present invention. The bathtub A of the present invention is mainly composed of a bottom plate 1, two side plates 2, and two side plates 3 (however, in FIG. 1, only one side plate 2 and one side plate 3 are shown for explanation). The two side plates 2 and the two side plates 3 are erected on the bottom plate 1 to form a bathtub. The upper surface of the bottom plate 1 has a configuration in which a flat rectangular parallelepiped plate is stacked on the center portion, and the upper surface of the bottom plate 1 has a configuration in which the central portion is one step higher than the four edge portions 4a. Each side plate 2 and each side plate 3 are erected on the edge substantially vertically.

Specifically, the insertion protrusions 5 provided at the lower ends of the side plate 2 and the side plate 3 are fitted into the kerf 6 formed in the flat surface on the side of the step 4b of the end edge 4a of the bottom plate 1, respectively. In this case, as shown in FIG. 1, a plurality of elastic members 7 project substantially hemispherically from the side surface of each step 4 b of the edge 4 a of the bottom plate 1, so that the side plate 2 that comes into contact with these elastic members 7 or While pressing the lower end side surface of the side plate 3 to compress the elastic member 7, the insertion protrusions 5 provided at the lower end of the side plate 2 and the side plate 3 are fitted into the cut grooves 6 of the bottom plate 1.

  As described above, the side plate 2 and the side plate 3 are pressed against the elastic member 7 and the side plate 2 and the like are erected on the bottom plate 1, so that while the side plate 2 and the side plate 3 are erected on the bottom plate 1, the bottom plate 1. Therefore, a restoring force is always applied to the side surface of the step portion 4b of the end edge portion 4a and the lower portion of each side plate to return the elastic member 7 to the original position. For this reason, the adhesion between the bottom plate 1 and the side plate is increased, and the side plate 2 and the side plate 3 that are erected are prevented from accidentally coming out of the bottom plate 1. However, if the elastic member 7 is protruded too much, a gap is formed in the joint surface between the bottom plate 1 and the side plate 2, so that the protruding length is preferably about several centimeters depending on the hardness of the elastic member 7.

  Further, as shown in FIG. 1, when the side plate 2 and the side plate 3 are erected on the bottom plate 1, a depth slightly smaller than the size of the elastic member 7 at a position where the elastic member 7 of the joint surface at the lower end of the side plate contacts. If the dent 8 of about several centimeters is provided, the elastic member 7 is compressed and fitted into the dent 8, and the joining is more difficult to shift.

  On the other hand, as shown in FIG. 2, the adjacent side plate 2 and side plate 3 are joined by joining the adjacent side plate 2 and side plate 3 with a buckle fitting 9. Also in this case, as shown in FIG. 1, since the elastic member 7 protrudes in a substantially hemispherical shape from a plurality of locations on the joining surface of the side plate 2, when the side plates are joined together by the buckle fitting 9, the side plate 3 is pressed. The elastic member 7 is press-fitted into the recess 8 of the opposing side plate 3. Accordingly, the side plate 2 and the side plate 3 that are joined are always subjected to a restoring force to return to the original size of the elastic member 7 while they are erected, thereby increasing the adhesion between the side plates and joining the side plates 2 and 3. Will not come off. In FIG. 2, one buckle metal fitting 9 is used for joining the side plate 2 and the side plate 3, but two buckle metal fittings 9 may be used as shown in FIG. A number of buckle fittings 9 may be used.

The buckle fitting 9 is normally used as a joining fitting such as a trunk. When the side plate 2 and the side plate 3 are joined, a handle 9a having one end pivotally attached to a base 9f attached to the side plate 3 is raised, and a hook 9c having one end locked in the long hole 9b of the handle 9a is attached to the side plate. When the handle 9a is tilted by being hooked on the bent edge 9e of the second locked metal 9d, the hook 9c pulls the locked metal 9d, and the side plate 2 and the side plate 3 are joined. The buckle fitting 9 has a simple configuration that is simply attached to the side plate 2 and the side plate 3 and is easy to operate.

  Further, the configuration of joining the side plates by the buckle metal fitting is not limited to the above-described configuration. For example, as shown in FIG. 18, the metal fitting 39 is attached to the side plate 3 and the metal fitting 40 is attached to the side plate 2. Good. Further, if the distance between the bent edge 41 of the locked metal fitting 39 and the tip of the hook 45 can be expanded and contracted, the force for attracting the side plate 2 and the side plate 3 of the buckle metal fitting can be adjusted. Optimal force can be applied to the packing material 10. Therefore, as shown in FIG. 18, the hook having one end locked in the long hole 44a of the handle 44 pivoted at one end on the base 40a of the locking bracket 40 is divided into two, and a nut is attached to the shaft at the tip of one hook piece 42. If the portion 43 is provided, a screw is cut on the outer periphery of the shaft of the other hook piece 45 to form a bolt portion, and the bolt portion of the shaft of the hook piece 45 is screwed to the nut portion 43 of these hook pieces 42, the hook If the piece 45 is rotated, the position of the tip of the hook piece 45 is changed, and the force for attracting the side plate 2 and the side plate 3 of the buckle fitting can be adjusted.

  Further, in the configuration shown in FIG. 18, a hinge 46 is provided in the middle of the locked metal fitting 39 as shown in FIG. 19, so that the free end of the locked metal fitting 39 can be bent and folded on the side plate 2 side. You may make it the structure which hooks the hook piece 45 on the curved edge 41. FIG. With such a configuration, the locked metal fitting 39 can be folded on the side surface of the side plate 3, so that it is avoided that the bent edge 41 is bent by colliding with other members during assembly or disassembly of the bathtub. Can do.

Moreover, waterproofing of the joining location of the bottom plate 1 of the bathtub A, each side plate 2 and the side plate 3 is performed by putting the packing material 10 along the joining surface. As shown in FIG. 1, a packing material 10 is provided along each joint surface of the side plate 2, the side plate 3, and the bottom plate 1. In FIG. 1, the packing material 10 is fitted into the notches provided in the bottom plate 1, the side plate 2, and the side plate 3 so as to slightly protrude from the respective joining surfaces, but the packing material 10 is inserted into the side plate 2, the side plate 3, and the bottom plate 1. The method of extending along each joint surface is not limited to this configuration, and other configurations may be used. In addition, the configuration in which the packing material 10 is arranged is when the side plate 2 and the side plate 3 are joined so that the hot water filled in the bathtub A does not leak, as in the configurations shown in FIGS. 1, 2, and 3. Or, when the side plate 2 and the side plate 3 are joined to the bottom plate 1, a configuration in which the packing material 10 is arranged in two rows at each joining surface is preferable.

In the assembling procedure of this bathtub A, first, the bottom plate 1 is placed in a bathroom washroom or the like, and the bather is put on a wheelchair and placed on a place that is one step higher than the edge 4a at the center of the bottom plate 1. Then, the respective insertion protrusions 5 provided at the lower ends of the side plate 2 and the side plate 3 are fitted into the respective cut grooves 6 formed in the plane beside the step portion 4b of the four end edges 4a of the bottom plate 1, Two side plates 2 and side plates 3 are erected on the bottom plate 1. And the adjacent side plate 2 and the side plate 3 are joined by fastening the buckle fitting 9. Then fill up bathtub A with hot water. When a bather leaves the bathtub, the hot water in the bathtub A can flow out and drain if one of the four side plates that make up the side wall of the bathtub is removed. You can go outside while riding in a wheelchair.

  Note that any one of the side plates removed and drained must be performed with water pressure applied to the side plates, which requires labor for the caregiver, but the side plate 2, the side plate 3 or the bottom plate 1 If the hole for draining the hot water in the bathtub A is drilled at any of the locations, and the rubber plug is configured in the hole, the hot water in the bathtub A will be drained without removing the side plate. It can be convenient. And the hole for draining the hot water in the bathtub is drilled in either the bottom plate or the side plate, and the rubber plug is put in the hole. This configuration can be adopted also in the following bathtubs B to E. it can.

Next, Example 2 will be described with reference to FIG.
In the bathtub B of the second embodiment, only one side plate 12 of the four side plates constituting the side wall of the bathtub is detachable, and the other side plates 13 are fixed integrally with the bottom plate 11 in advance. Has been. When the side plate 12 is erected on the bottom plate 11, a plurality of insertion protrusions 15 provided at the lower end of the side plate 12 are provided with a plurality of cuts provided on a plane beside the step portion 14 b of the edge 14 a of the bottom plate 11. This is done by fitting into the groove 16. Further, the other side plate 13 and the side plate 12 adjacent to each other are joined by buckle fittings (not shown) similar to those in the above embodiment.

  Similar to the configuration of the bathtub A, also in this embodiment, a plurality of substantially hemispherical elastic members 17 protrude from two joint surfaces of the side plate 13 with the side plate 12 and abut against the lower side surface of the side plate 12. Since the substantially hemispherical elastic member 17 protrudes from the side surface of the step portion 14 b of the edge portion 14 a of the bottom plate 11, when inserting the insertion protrusion 15 into the groove 16 of the bottom plate 11, the side plate 12 is moved to the side plate 13. It is necessary to compress the elastic member 17 by pressing against the joining surface of the bottom plate 11. Further, the waterproofing of the joining portions of the side plate 12, the bottom plate 11, and the side plate 13 is performed by placing the packing material 18 along the joining surface. Further, in the same manner as in the first embodiment, a recess (not shown) may be provided on the joint surface of the side plate 12 where the elastic member 17 faces and the elastic member 17 may be fitted.

Unlike the bathtub A, the bathtub B is erected on the bottom plate 11 by simply standing the side plate 12 and joining the adjacent side plate 13 with the buckle fitting, thereby reducing the labor of the caregiver who assembles the bathtub. Can be convenient. In addition, when using the tub B like the tub A, it is possible to bring it into a bathroom where a normal tub is already installed such as at home, but the tub B is a wheelchair passenger. Since it can be used without any problems even if it is used as a normal bathtub by others, it may be installed in the bathroom as a normal bathtub. Then, the side plate 12 may be removed and used only when entering the bathtub B with a wheelchair.

Further, as the insertion protrusion 15 provided at the lower end of the side plate 12 of the bathtub B, a configuration in which a grazing 35 as shown in FIG. 13 is driven so as to protrude from the lower end of the side plate 12 may be adopted. In this case, a convex portion 36 as shown in FIGS. 15 and 16 is provided in the kerf 16 formed in the end edge portion 14 a of the bottom plate 11. When the side plate 12 is erected on the bottom plate 11, as shown in FIG. 14, as shown in FIG. Disappear.

  Further, as shown in FIG. 17, as the insertion protrusion 15, a commercially available screw tip 37 is attached, and in the cut groove 16 formed in the end edge portion 14 a of the bottom plate 11, the outer diameter of the screw tip 37 is slightly increased. It is good also as a structure which inserts the nut 38 of a big diameter. With such a configuration, once the side plate 12 is erected on the bottom plate 11, the unevenness on the side of the screw tip 37 is caught by the unevenness on the side of the nut 38 when the side plate 12 is slightly inclined. For example, there is no possibility that the bathtub B is accidentally removed when hot water is contained. On the other hand, if the side plate 12 is lifted right above with a certain amount of force, the unevenness of the screw tip 37 and the unevenness of the nut 38 can be removed while being rubbed. Thus, if it uses the structure which uses a commercially available member for the insertion protrusion 12, the process of the side plate and bottom plate of the bathtub B will become very easy. In the above description, the case of the bathtub B has been described. In the case of the bathtub A as well, a configuration in which the shaving 35 and the screw tip 36 are used as the insertion protrusion 5 and the nut 37 is fitted in the kerf 6 is employed. It is possible.

Next, Example 3 will be described with reference to FIG.
In the bathtub C of the third embodiment, only the side plate 20 has a detachable configuration, and the other parts of the bathtub C are fixed integrally in advance. Therefore, when the bathtub C is assembled, the assembly is completed if the side plate 20 is attached. Specifically, a hinge shaft member 22a provided at the lower end of the side plate 20 is inserted from the side into a hinge tube member 22b provided on the back surface of the bottom plate 19, and the two side plates 21 to which the inner side surfaces of the side plate 20 are joined, and It is rotated so as to contact the bottom plate 19. And in order to join the side plate 20 and the two side plates 21, the buckle metal fitting (illustration omitted) provided in the appropriate location of the side plate 20 and the side plate 21 is fastened. This buckle fitting is the same as in the above embodiment. The buckle fitting may be attached not only to the outside of the bathtub but also to the inside. If the buckle bracket is attached to the inside of the bathtub, the wheelchair passenger can conveniently tighten the buckle bracket. The bathtub C is provided with legs or the like in the bathtub C as shown in FIG. 5 so that the side plate 20 can be freely rotated by a hinge 22 (comprising a shaft member 22a and a tube member 22b). It is necessary to provide a space between the floor. Further, the waterproofing of the joint portion between the side plate 20, the bottom plate 19 and the side plate 21 is performed by placing the packing material 23 along the joint surface.

Next, Example 4 will be described with reference to FIG.
The bathtub D of the fourth embodiment is mainly composed of a bottom plate 24, two side plates 25, and two side plates 26. A plate-like fastener 27 in which approximately half is a frame-shaped hook is provided at an appropriate portion of the four edge portions on the back surface of the bottom plate 24, and only the hook portion of the fastener 27 is the end of the bottom plate 24. It is attached in parallel to the back surface of the bottom plate 24 so as to protrude outward from the edge. Further, a rubber piece 29 is attached to an appropriate location on the back surface of the bottom plate 24 so that a space is formed between the bottom plate 24 and the floor surface of the bathroom (see FIGS. 7 and 8). Further, hooking metal fittings 28 having a substantially J-shaped vertical cross section are attached to the lower portions of the side plates 25 and 26 so that the hooks at the front end face the outer side of each side plate.

  When assembling the bathtub D, the hooking metal fitting 28 of the side plate 25 is obliquely fitted into the hook portion of the fastener 27 of the bottom plate 24 as shown in FIG. In this state, the side plate 25 is stood upright. If it does so, as shown in FIG. 8, the hook part of the hook metal fitting 28 will be caught in the hook part of the fastener 28, and will not come out upward. Although the case of the side plate 25 has been described here, the side plate 26 is assembled in the same procedure. The order of assembling the four side plates constituting the side wall of the bathtub D may be assembled from any side plate.

  In this state, since the side plate 25 and the side plate 26 are not fixed to the bottom plate 24, the adjacent side plate 25 and the side plate 26 are respectively joined by buckle fittings (not shown) similar to the above embodiment, The joining between the side plate 25 and the side plate 26 and the joining state between the side plate and the bottom plate 24 are stabilized. In order to make it more stable, the side plate 25 and the side plate 26 may be joined using a plurality of buckle fittings as shown in FIG.

  Next, the waterproofing method of the bathtub D is demonstrated using FIG.9 and FIG.10. First, the side plates are joined to each other, and the packing material 30 is placed along two joining surfaces of the side plate 26 and the side plate 25 so as to protrude from the joining surface by several centimeters. In such a configuration, when the side plate 25 and the side plate 26 are joined by fastening the buckle fitting 31, the protruding portion of the packing material 30 is compressed. Get higher.

  Next, another method for joining the side plates will be described with reference to FIGS. The L-shaped packing material 32 is attached along the both side ends of the surface which becomes the inner surface of the bathtub D of the side plate 26. A permanent magnet 33 is fitted in a part of the L-shaped packing material 32 that comes into contact with the side plate 25 when the side plate 25 and the side plate 26 are joined. On the other hand, a magnetic absorption body 34 to which a permanent magnet 33 such as metal is attracted is fitted at a position of the side plate 25 where the L-type packing material 32 of the side plate 26 abuts. With such a configuration, the L-shaped packing material 32 attracts the side plate 25 due to the magnetism of the permanent magnet 33 and fills the gaps at the joining portion, so that the waterproof property is enhanced. Further, when hot water is poured into the bathtub D, the L-type packing material 32 is pressed against the side plate 25 and the side plate 26 by the water pressure of the hot water, and is more closely attached.

  Further, regarding the waterproofing method of the side plate 25 and the joining surface of the side plate 26 and the bottom plate 24, any of the above-described joining methods of the side plates is adopted, the side plate 25 and the side plate 26 of the bathtub D and the bottom plate 24. The four sides of the bottom plate 24 joined to each other are sealed by providing an angle-like packing material (not shown). Furthermore, if the cross-sections of the side pieces on both sides of the packing material in the form of an angle are made to have a sharp pointed shape like a blade, the side plates 25 and the like are strongly adhered by water pressure.

  In addition, since the side plate 25 and the side plate 26 of the bathtub D have a plurality of hooks 28 protruding from the lower ends, the hooks 28 are in direct contact with the floor surface when the bathtub D is disassembled and stood against the wall. There is a risk of damage. Therefore, if a hook-like guide piece longer than the hook metal fitting is protruded from the lower end of the side plate so that the hook metal plate 28 is not damaged, and the bottom plate 24 is appropriately provided with a hole for fitting the guide piece, the side plate 25 and the side plate Positioning when standing 26 on the bottom plate 24 is facilitated.

Next, Example 5 will be described with reference to FIGS.
In the bathtub E of the fifth embodiment, only the side plate 47 has a movable configuration, and other parts of the bathtub E are fixed integrally in advance. The upper end of one side portion of the side plate 47 is pivotally supported on the side wall end surface of the adjacent bathtub E by a shaft 48 so that the portion can be a fulcrum. The other side of the side 47 is connected to the adjacent side plate using a buckle fitting (not shown). A hook 49 is provided on the outer surface near the other side of the side plate 47, and one end of the rope 50 is tied to the hook 49. The other end of the rope 50 is connected to a winder 53 installed on a table 52 through a pulley 51 installed on the ceiling of the bathroom. An insertion projecting piece 54 is provided at the lower end of the side plate 47, and can be fitted into a notch (not shown) provided on a flat surface on the side of the step of the edge of the bottom plate 55 of the bathtub E. Further, the waterproofing of the joint portion between the side plate and the bottom plate 55 and the adjacent side plate is performed by placing the packing material 56 along these joint surfaces.

  A method of using the bathtub E will be described. When the rope 50 is wound up by the winder 53 from the state in which the side plate 47 is erected on the bottom plate 55 as shown in FIG. 20, the side where the hook 49 of the side plate 47 is provided as shown in FIG. Lift as a fulcrum. With the side plate 47 jumped up, the passenger in the wheelchair enters the bathtub E together with the wheelchair. Thereafter, when the winder 53 is operated from the bathtub E and the rope 50 is fed out, the side plate 47 rotates, and the side plate 47 is erected on the bottom plate 55 as shown in FIG. At that time, the insertion protrusion 54 at the lower end of the side plate 47 fits into the cut groove of the bottom plate 55. If the winder 53 is provided with a ratchet, the rope 50 is stopped at the position where the winder 53 is stopped, and the rope 50 does not reverse by mistake, which is more desirable.

  According to the configuration of the bathtub E, a passenger in a wheelchair can take a bath alone without helping an assistant. In this embodiment, the rope 50 is operated by using the winder 53. However, the rope 50 can be operated by pulling or loosening the rope 50 by hand, and the rope 50 can be specified. When fixing by length, it is good also as a structure which connects the end of the rope 50 to the appropriate location of the bathtub E. FIG.

  Further, in the present embodiment, the side plate 47 jumps up. However, as shown in FIG. 22, a hinge 57 may be used to open the side plate 47 like a door. In this case, although not shown, the free end of the side plate 47 and the side plate end adjacent to the bathtub E are fixed using the same buckle fitting as in the above embodiment.

As a result, the lower end of the side plate 59 or 60 forms a key-shaped projecting piece with a frame 59a or 60a extending horizontally outward and bent upward from its outer edge. In addition, as shown in FIG. 26, packing materials 64 are provided on two sides of the frame body 60a serving as both side ends of the side plate 60 so as to cover one surface of the side. The packing material 64 is not affixed to the side plate 59.

Next, a method for assembling the bathtub F will be described. The side plates 59 are erected so as to face the respective edge portions on the upper surface of the bottom plate 58. At this time, as shown in FIG. 27, the side plate 59 is erected so that the protruding piece 63 of the side plate 59 is hooked on the bent portion of the locking piece 61 having a cross-sectional key shape of the bottom plate 58. Then, the two side plates 60 are erected so as to face each other in the same manner. Adjacent side plates 59 and side plates 60 are joined using a buckle fitting 65 as shown in FIG.

The buckle fitting 65 includes a hooking tool, a holding tool 65a with a buckle, and a hook-like locked tool 65b. For example, the locking tool 65a is attached to the edge of the reinforcing member 60c of the side plate 60, and the locked tool. 65b is fixed to the end edge of the reinforcing member 59c of the side plate 59, the buckle of the locking tool 65a is raised, the hooking tool is hooked on the locked tool 65b, and the buckle is returned to its original position and locked.

Increases waterproofness. The length of the hooking tool of the locking tool 65a can be adjusted.

Further, as shown in FIG. 23, if the pin 75 is protruded from the location closest to the joint surface with the side plate 60 above the inner side surface of the two side plates 59 erected opposite to each other, For convenience, the side plates 60 can be prevented from falling inward of the bathtub F.

A seventh embodiment of the present invention will be described below with reference to FIGS.
29 to 31 show a wheelchair bathtub G (hereinafter simply referred to as “tub G”) according to Embodiment 7 of the present invention. The bathtub G of the present invention has a configuration in which one of the four side plates is open as shown in FIGS. To do. Then, the edge of the bottom plate 72 on the open side is projected horizontally from the edge toward the outside of the bathtub G, bent upward at the outer edge, and from the upper edge to the center of the bottom plate 72. A locking piece 68 having a cross-sectional key shape is provided that protrudes horizontally toward the top and further hangs downward from its inner edge (in FIG. 31, the locking piece 68 is omitted). The locking piece 68 may be molded together when the bathtub G is integrally molded with a stainless steel plate or the like, or may be configured to be welded to the bathtub G afterwards.

In the above description of the present embodiment, the locking piece 68 is once protruded to the outside of the bottom plate 72 and bent upward there. You may make it the structure protruded horizontally toward the center of the baseplate 72 from the edge, and was made to hang down from the inner edge further. However, in this case, the position where the later-described packing material 71 of the packing material 70 is provided is shifted backward by temporarily folding the stainless steel plate or the like constituting the bathtub G and then folding it to the inside of the bathtub G at approximately 90 degrees. There is a need.

Also, the detachable side plate 66 shown in FIG. 32 attached to one end of the opening of the wheelchair bathtub G is integrally formed of a single plate made of stainless steel, aluminum, or the like in the same manner as the bathtub G. The side plate 66 shown in FIG. 32 is provided with a reinforcing material 67 horizontally in the center. The side plate 66 is provided with a key-shaped projecting piece 74 which is bent horizontally at the lower end and protrudes upward at the outer edge.

Next, a waterproofing method for the joint surface between the bathtub G and the side plate 66 will be described. First, for joining the two side plates 69 and the side plates 66 on both sides of the opening end of the bathtub G, as shown in FIG. A stainless steel plate or the like to be formed is bent at approximately 90 degrees inside the bathtub G to form an attachment margin 71 for the packing material 70, and the packing material 70 is attached vertically along the attachment margin 71. Furthermore, the surplus portion such as the stainless steel plate is folded and welded to the inside of the bathtub G. As for the joining of the bottom plate 72 and the side plate 66 of the bathtub G, as shown in FIG. 29 and FIG. 31, a margin 73 is erected on the edge of the bottom plate 9 on the opening side, and along the margin 73. The packing material 70 is stuck horizontally. The pasting 73 is provided with a plurality of notches, and the width of the locking piece 68 is adjusted so that the wheelchair wheel can pass through.

Next, a method for assembling the bathtub G will be described. When the side plate 66 is erected on the opening side of the bottom plate 72 of the bathtub G, the side plate 66 is slid from either the right or left side of the opening side of the bathtub G, and the protruding piece 74 at the lower end of the side plate 66 is attached to the bathtub G. It fits in the locking piece 68. Then, the two side plates 69 and the side plates 66 of the bathtub G are joined using the same buckle fitting as in the sixth embodiment (not shown). As described above, the packing material 70 is provided at the joint between the two side plates 69 and the side plate 66 of the bathtub G. By joining with the buckle fitting, the two side plates are joined with a certain amount of force. The waterproofness of the bathtub G increases.

In this embodiment. The stainless steel plate or the like constituting the bathtub G is bent approximately 90 degrees inside the bathtub G to form the margin 71 for the packing material 70. However, as shown in FIGS. 33 and 34, the stainless steel plate or the like constituting the bathtub G is attached to the bathtub. The margin 71 of the packing material 70 may be formed by bending the outer side of the G approximately 90 degrees. Such a configuration is desirable because the sanitary upper tub G has less accumulated germs and dirt.

In the present embodiment shown in FIG. 29, the edge of the bottom plate 72 on the open side as described above is projected horizontally from the edge toward the outside of the bathtub G. It is configured to be provided with a key-shaped locking piece 68 that is bent upward, protrudes horizontally from its upper edge toward the center of the bottom plate 72, and further hangs downward from its inner edge. As shown in FIG. 33, a portion that makes the locking piece 68 protrude horizontally from the end edge portion of the bottom plate 72 toward the outside of the bathtub G protrudes from the entire surface of the end edge portion. You may make it the structure which makes a part bend upward and protrudes by the outer edge. Only a part of the locking piece 68 is bent upward at the outer edge thereof, so that the wheel of the wheelchair can pass through the gap without the bent part upward of the locking piece 68.

Further, for joining the bottom plate 72 and the side plate 66 of the bathtub G, as shown in FIGS. 29 and 31, a plurality of pastes 73 are erected on the edge of the bottom plate 66 on the opening side, and along the paste margin 73. However, as shown in FIG. 33, the packing material 70 protrudes horizontally from the edge of the bottom plate 72 of the locking piece 68 toward the outside of the bathtub G. Alternatively, it may be configured to be horizontally attached to the upper surface. However, when the packing material 70 is applied to the upper surface of the portion of the locking piece 68 that protrudes horizontally from the edge of the bottom plate 72 toward the outside of the bathtub G, the wheelchair is placed on the upper surface of the bottom plate 72. At this time, the wheel of the wheelchair passes therethrough and the packing material 70 may be worn out or peeled off. Therefore, as shown in FIG. 35, the packing material 70 is placed on the bottom surface of the projecting piece 74 of the side plate 66. You may make it the structure which affixes.

Further, in this embodiment, the side plate 66 has a configuration in which a reinforcing material 67 is provided horizontally in the center, but as shown in FIGS. 36 and 37, a depth of 5 mm is used instead of the reinforcing material. A configuration may be adopted in which a plurality of convex presses are inserted. The side plate 66 is easier to be integrally molded than the configuration in which a separately prepared reinforcing material is provided, which is desirable in terms of hygiene. In addition, the structure which inserts this convex press can be employ | adopted also in the case of the side plate 59 and the side plate 60 of Example 6. FIG.

In place of the locking pieces and the protruding pieces of the sixth and seventh embodiments, the outer edge of the bottom plate 58 or 72 is bent upward as shown in FIG. 38, and the upper edge is horizontally directed toward the center of the bottom plate 58 or 72. A bent section key-shaped locking piece 61 ′ or 68 ′ is formed, and a lower end edge of the side plate 59, 60 or 66 is formed horizontally as a cross-section key-shaped protrusion 63 ′ or 74 ′. Protruding piece 63 'or 74' can be engaged with locking piece 61 'or 68' by providing packing material 62 'or 64' inside 'or 68'. Further, as shown in FIG. 39, the structure in which the upper edge of the locking piece 61 'or 68' is curved can be similarly engaged.

As described above, the bathtubs A to G are configured, and even if hot water is put into these bathtubs, the hot water hardly leaks to the outside, and even if it leaks, the amount of the hot water is small. There is no inconvenience.

As for the materials of the bathtubs A to E, synthetic resin or stainless steel may be used, and wood may be used. In the case of wood, the surface is waterproofed to prevent it from getting heavier or rotting with hot water. A paint may be applied or a transparent acrylic resin cover may be covered integrally. Here, a method of applying the waterproof paint will be specifically described. First, a waterproof paint such as an epoxy resin is applied to each side plate and bottom plate which are inside the bathtub. Then, in order to make it easier to peel off later, a flat plate coated with a release agent such as oil is pressure-bonded to the coated surface. As the flat plate used here, a smooth mirror-finished metal plate or acrylic plate with no irregularities or protrusions is used. Then, after the waterproof paint is fixed, the pressure-bonded flat plate is removed. When the waterproof paint is fixed by crimping the flat plate in this way, the surface of the waterproof paint is smoothly finished like a mirror, and when using these side plates and bottom plate, the touch is very good when bathing in the bathtub. Become. In the above description, it is described that the waterproof paint is applied to the side plate and the bottom plate which are inside the bathtub, but the waterproof paint may be applied to any side of the side plate or the bottom plate.

Moreover, you may make it the structure which affixes a metal plate to the location which contact | abuts with the other member of the side plate which comprises these bathtubs A-E, or a baseplate, or a location where a wheelchair rests or collides when bathing. In this way, if the parts that other members and wheelchairs touch are covered with a metal plate, even if the bathtub is assembled and disassembled many times and used for many years, the joint surface of the side plate and the bottom plate will be rubbed. It is possible to avoid being scraped off, and the service life of the bathtubs A to E can be extended.

When sticking a metal plate to the side plate or the bottom plate, it may be configured to affix the metal plate, avoiding the location where the packing or elastic member protrudes, or after attaching the metal plate to an appropriate location of the side plate or the bottom plate, You may make it the structure which attaches packing and an elastic member from the top. When the material of the bathtubs A to E is wood, it is easier to install the packing or elastic member on the metal plate because the mounting surface is smoother, and between the packing and the metal plate. There is almost no gap, and the waterproofness of the bathtubs A to E is increased. When attaching a locking metal fitting, a hinge, or the like to the side plate or the bottom plate, the attachment is strengthened if the metal plate is attached from above.

Further, the joining of the side plate and the bottom plate and the mutual joining of the side plates are not limited to those of the first to seventh embodiments, and can be configured to be recombined with those of the other embodiments. The configuration can be selected and adopted. Moreover, in Examples 1-7, although the buckle metal fitting is provided in the joining of adjacent side plates, it is not restricted to this buckle metal fitting. Examples of the joining structure include a pinch structure and a structure using a locking tool using a wedge. In short, any structure may be used as long as a locking body is provided on one side plate of adjacent side plates, a locked body is provided on the other side plate, and these locking bodies are locked to the locked body. In the second, third, and seventh embodiments, the one side plate 12 and the side plate 20 are detachable. However, the present invention is not limited to this, and two or three side plates may be detachable.
