Description

  The present invention relates to a portable toilet.

In recent years, with the advent of the elderly, the nursing of bedridden elderly people at home has become a major social problem. In this care, the excrement is particularly difficult to process. In view of such circumstances, various portable toilets that can be placed like furniture in bedrooms and hospital rooms have become commercially available. In this portable toilet, for example, as disclosed in Patent Document 1, a bucket is disposed below the toilet seat. And the excrement of the care recipient falls in this bucket. The bucket is taken out of the container storage room by a caregiver in a timely manner and processed in a toilet room or the like.
JP 2002-282164 A

  If the portable toilet disclosed in Patent Document 1 is used, it is easy for the care recipient to excrete, but the problem remains. That is, if a user goes alone (without help from a caregiver) to a portable toilet, the user may fall over and get to the front of the portable toilet. Therefore, in the front part of the portable toilet, there is a step between the toilet seat and its peripheral part, so if the part where the hand is worn is the outer edge of the toilet seat, a local force acts on the hand, It cannot be said that there is no possibility of an unexpected situation.

  Therefore, this invention makes it the technical subject to eliminate such a malfunction.

Technical measures taken to solve the above problems are:
A chair portion, a bucket detachably disposed on the chair portion, and a case disposed on a rear portion of the chair portion and pivotally attached to a toilet seat. In the portable toilet housed in the bucket, the front end of the bracket provided below can be inserted into and removed from the gap defined between the outer frame of the chair and the toilet seat. The portable toilet is constructed by arranging an auxiliary tool made of an elastic body having substantially the same height as the toilet seat.
In this case, it is preferable that the height of the mattress on the bed adjacent to the bed is substantially the same as the height of the auxiliary tool.

  According to the portable toilet of the present invention, the steps around the toilet seat are substantially eliminated, so that even if an elderly person or a physically weak person stumbles and puts a hand on the outer edge of the toilet seat, local force acts on the hand. There is nothing wrong. In addition, when the portable toilet of the present invention is adjacent to the bed, if the height from the floor surface of the toilet seat and the height from the floor surface of the mattress on the bed are substantially the same, there will be no step between the two. Easy transfer between.

 DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment embodying a warm water washing toilet seat device of the present invention will be described in detail with reference to the drawings.

   1 to 3, the portable toilet 10 includes a chair unit 20. The chair portion 20 is provided with a support plate 22 that can slide in the front-rear direction. A hole 24 is formed in the support plate 22. A resin outer bucket 30 is fitted into the hole 24, and an edge 32 of the outer bucket 30 is engaged with the support plate 22. In this way, the outer bucket 30 is suspended from the support plate 22.

 An inner bucket 40 made of resin is accommodated in the outer bucket 30. The opening of the inner bucket 40 is closed with a lid 50 when not in use.

A cleaning unit 60 is attached to the rear portion of the support plate 22. The cleaning unit 60 includes a case 62, a toilet seat 64 pivotally attached to the case 62 , and a cleaning mechanism (not shown) installed in the case 62 . As will be described later, the cleaning mechanism opens the inner bucket 40, and after the user seated on the toilet seat 62 excretes, hot water is sprayed from a nozzle (not shown) to the user's anus by a predetermined operation. The cleaning is done.

 When the portable toilet 10 is not used, as shown in FIG. 1, the opening of the inner bucket 40 is closed with a lid 50, and in this state, the toilet seat 62 is placed in the use position. When the portable toilet 10 is used, that is, when a care recipient wants to excrete, the caregiver first raises the toilet seat 62 (FIG. 3) and pulls out the support plate 22 slightly forward (FIG. 4). Then, the lid 50 is removed to open the inner bucket 40 (FIG. 5), the support plate 22 is returned to the original position, and the toilet seat 62 is set to the use position. Then, the care recipient sits on the toilet seat 62 and excretes, and is washed with warm water. Excrements (urine / urine) are contained in the inner bucket 40.

 When such a series of excretion is completed, the excrement stored in the inner bucket 40 needs to be thrown away into the toilet (or filthy logistics) in the toilet room, so the support plate 22 is pulled out slightly forward, and the inner bucket The inside 40 is taken out (FIG. 6). As will be described in detail below, the inner bucket 40 is configured to prevent the relative rotation of the container main body 42 containing the excrement with respect to the handle 44, and therefore is slightly forward.

 In the above description, the support plate 22 is pulled out slightly forward in order to avoid interference between the lid 50 and the inner bucket 40 and the nozzle that are to be taken out upward.

 The inner bucket 40 will be described in detail with reference to FIGS.

 The inner bucket 40 includes a container body 42 and a handle 44. The handle 44 has an inverted U-shape, and free end portions 44a and 44a thereof are rotatably connected to an integral pin 46 and 46 at the center portion of the outer surface of the container body 42 in the longitudinal direction. That is, both the free end portions 44a and 44a of the handle 44 having an inverted U shape are pivotally attached to the pins 46 and 46 of the container body 42, so that the handle 44 has the pins 46 and 46 which are both pivot points. The container main body 42 can be rotated about the connecting pivot X.

 A rest body 49 that integrally holds the handle in the non-use position at the rest position is integrally formed at the right end of the pivot axis X of the container body 42. In addition, upper edge portions 48 and 48 projecting outward are integrally formed on the upper surface portion of the container body 42 on the left side of the pivot X, and the end portions 48a and 48a thereof are erected. The free end portions 44a and 44a face each other at a predetermined interval.

 As is apparent from FIGS. 7 and 8, the container body 42 is not symmetrical with respect to the pivot axis X, and has a large right volume. Since the excrement is mainly accommodated in the right side portion of the container main body 42, the center of the pivot X and the center of gravity of the container main body 42 containing the excrement are not on the same vertical line, and the container main body 42 is not in the outer bucket. When the raised handle 44 is lifted up while seated in the container 30, the container body 42 tries to rotate around the pivot X in the clockwise direction. However, the free end portions 44a and 44a of the handle 44 are engaged with the end portions 48a and 48a of the upper edge portions 48 and 48 of the container main body 42 to prevent further rotation. Thereby, the spillage of excrement accompanying the large rotation of the container body 42 is prevented.

 Reference is again made to FIG. In the state shown in FIG. 1, a stepped portion 68 is unavoidable on the toilet seat 64 and its peripheral portion (specifically, between the toilet seat 64 and the front and side portions of the outer frame portion (peripheral portion) of the chair portion 20). Defined. When the stepped portion 68 is provided with auxiliary tools 90 and 90 having substantially the same height as the toilet seat 64 as shown in FIG. 10, the stepped portion is eliminated as shown in FIG. As a result, even if an elderly person or a physically weak person sits on the assisting device 90 at the outer edge of the toilet seat, local force does not act on the hand.

Thus, the auxiliary tool 90 is formed of a urethane resin or other elastic body. In this case, the outer surface of the assisting tool 90 may be colored with a color other than white from the viewpoint of relieving the user's mind or considering the low vision person. Instead of the urethane resin, the auxiliary tool 90 may be manufactured from a bag or a tree (particularly soft rubber tree) filled with a gel agent. When the assisting device 90 is made from a tree, particularly a soft rubber tree, even if an elderly person or a physically weak person sits on the assisting device 90 on the outer edge of the toilet seat, a local force acts on the hand. There is nothing wrong. When the auxiliary tool 90 is manufactured from wood, particularly soft rubber wood , it is desirable to use urethane coating for improving the design, but other coating may be used.

 Further, in order to stabilize the auxiliary tool 90, a planar fastener 92 is used, and as shown in FIG. 12, it is detachably attached to the bottom surface of the stepped portion 68 (specifically, the edge portion 32 of the outer bucket 30). As shown in FIG. 13, a bracket 96 is provided on the auxiliary tool 90, and the tip of the bracket 96 is inserted into a gap 28 (see also FIG. 1) formed on the inner surface of the outer frame portion of the chair portion 20. It may be removably fitted.

 As shown in FIGS. 14 and 15, the portable toilet 10 equipped with the auxiliary tool 90 is adjacent to the bed 100, the height from the floor surface F of the toilet seat 64 and the floor surface F of the mattress 102 on the bed 100. If the height from the center is made substantially the same, the step between the toilet seat 64 and the mattress 102 is eliminated by the auxiliary tool 90, and transfer between the two can be performed easily.

 As shown in FIGS. 14 and 15, when the portable toilet 10 equipped with the auxiliary tool 90 is adjacent to the bed 100, it is convenient for the user to provide the night light 98 on the auxiliary tool 90. This is because when the user gets off the bed 100 and uses the portable toilet 10 at night, the user can use the night light 98 to be portable without turning on the installed stand on the headboard of the bed 100 in a twisted manner. This is because the exact position of the toilet 10 can be recognized. As the night light 98, it is best to apply a nocturnal paint to a predetermined section on the surface of the auxiliary tool 90. Of course, nocturnal paint may be applied to the entire surface of the auxiliary tool 90.
