Description

  The present invention relates to a portable toilet that can be transported, and more particularly to a portable toilet in which a toilet seat is provided with a cleaning device.

  A chair-type portable toilet that is used by elderly people and people with disabilities in their rooms and hospital rooms is known, but in recent years, portable toilets with a cleaning device for cleaning the buttocks in the toilet seat have become widespread. ing. For example, see Patent Document 1.

  In a cleaning device that cleans the buttocks, the nozzle is generally cleaned while the nozzle is retracted. In the portable toilet, the cleaning water is trapped in a bucket placed on a chair. Since it is necessary, the bucket is generally positioned so as to overlap the lower part of the nozzle so that the washing water can be reliably trapped. Therefore, when removing the bucket, simply lifting the bucket vertically, the bucket rear end and nozzle, and a guide plate for guiding cleaning water to the bucket below the nozzle are unavoidable. There was a problem that the rear end of the interference.

  For this measure, in Patent Document 1, the bucket is not placed directly on the chair, but is placed on a drawer-type weight receiving member that slides in the front-rear direction. Thus, when throwing away the excrement, the bucket is first slid to the front position where the overlap can be eliminated via the weight receiving member, and the bucket is pulled up in the vertical direction in this state, so that the bucket is guided to the guide plate. It is devised so that it can be taken out without interfering with.

JP 2006-94901 A

  In the structure of Patent Document 1 configured as described above, the bucket can be taken out without interfering with the guide plate, but the removal method cannot be performed by one operation of lifting the bucket. In addition to the problem that the inconvenience remains, the structure of Patent Document 1 is indispensable for a portable toilet that needs to be stored and transported when it is not used or according to the user's location. Then, not only pull-out weight receiving members but also rails etc. are necessary, so it becomes inevitably heavy, especially when elderly people and physically handicapped people transport this portable toilet There was a problem of forcing hard work.

  In addition, if the weight receiving member is not securely stored, the bucket is not in the proper storage position, so the cleaning water for nozzle cleaning is not trapped in the bucket, and the excrement is reliably trapped. There were also problems such as being unable to do so, and excessive water splashing in the bucket due to the fall of excrement.

  In order to solve the above-described problems, a portable toilet according to the present invention includes a chair member on which a user is seated, a bucket serving as a container for excrement that is detachably placed on the seat surface of the chair member, and the chair member. A portable toilet provided with a toilet seat pivotably mounted at a rear end thereof and capable of taking a standing position and a flat position covering the upper surface of the bucket, the rear portion being the back side of the user when the toilet seat is seated A cleaning device having a nozzle provided on the side, a guide plate that is located below the nozzle in the retracted state and guides the cleaning water sprayed from the nozzle into the bucket, and is located below the guide plate, A bucket placed on the chair member so as to overlap the guide plate, the bucket taking a first position overlapping the guide plate and a second position sliding forward from the first position; As before The handle is slidably mounted on the chair member, and a handle is pivotally attached to the bucket so as to be swingable in a substantially horizontal manner on the front side of the chair member. It is.

  Since it is configured as described above, when throwing away the excrement in the bucket, the bucket slides forward simply by pulling out the handle provided on the front side of the bucket, and the handle is in a vertical state. In this state, the interference between the rear end of the bucket and the guide plate is also avoided, so that the bucket can be reliably and easily taken out with one take-out operation.

  In the portable toilet according to claim 2, in the retracted state of the handle, a shielding member is provided at a position behind the handle and in front of the front end of the bucket so as to close a gap between the bucket upper surface and the lower surface of the toilet seat. And the shielding member is configured to conceal the grip portion of the handle.

  In the present invention, since the bucket can be taken out while avoiding interference with the guide plate by one operation by grasping the handle, the handle is configured to be stored on the front side of the bucket. For this reason, there is a possibility that small water or pooled water may fall on the grip portion of the handle, but in the present invention, it can be reliably prevented by the shielding member.

  Furthermore, because the portable toilet is used in an environment that is not a dedicated toilet booth due to the shielding member, the sound during excretion has become a great resistance and discomfort for the user. In the present invention, since the gap is closed by the shielding member, it is possible to suppress the leakage of sound during excretion, and it is possible to achieve the effect that the user's resistance and discomfort can be greatly reduced.

  The portable toilet according to claim 3, wherein when the bucket is in the second position, the handle is configured to be in an upper position higher than the storage position, and the handle contacts the lower surface of the toilet seat at the upper position. The restraint force is applied to the movement of the toilet seat to the flat position.

  As a result, when the bucket is not sufficiently stored, the handle located at the upper position does not become a normal, substantially horizontal storage position, so that it can be easily determined that the bucket is insufficiently stored. In addition, since the toilet seat is also configured so as not to be in a regular flat position, an incomplete storage state of the bucket can be recognized also in this respect. Therefore, it is possible to prevent the nozzle from being accidentally washed or excreted in the bucket in a state where the washing water for washing the nozzle of the washing device and the excrement cannot be trapped.

  5. The portable toilet according to claim 4, wherein when the bucket is in the second position and the handle is in the upper position, the handle is moved to the retracted position in conjunction with the movement of moving the toilet seat to the flat position. Thus, the bucket is configured to slide to the first position.

  As a result, when the bucket is not in the normal storage position, the toilet seat is simply pushed to the flat position without bothering the toilet seat to the upright position and correcting the bucket to the normal storage position, or without worrying about the toilet seat. By sitting on the handle, the bucket automatically slides to the normal storage position as the handle moves to the storage position.

  In the portable toilet according to claim 5, low friction means is provided between a support surface that supports the bucket of the chair member and a contact surface between the support surface of the bucket.

  As a result, even a bucket containing pooled water or excrement can easily slide. Therefore, when the bucket is taken out or stored, and further, the handle is pushed in the storing direction by pressing the toilet seat. Even for the function of automatically sliding the bucket with respect to the movement, the operation can be surely ensured without unnecessarily increasing the strength of the handle.

  In the portable toilet according to claim 6, the shielding member is integrally formed on the upper end surface of the bucket, and a predetermined flat surface is formed on the upper end surface of the bucket between the shielding member and the grip portion of the handle. In addition, a concave draining groove having a length substantially corresponding to the grip portion is formed on the flat surface.

  As a result, even if there is small water that has exceeded the shielding member, it is possible to reliably trap it in the drain groove while the small water hangs down the upper surface of the bucket, so that the grip part of the handle is surely soiled. It can be prevented.

  According to the portable toilet according to the present invention, the portable toilet is extremely excellent in the field of portable toilets, in which the bucket can be easily taken out without making the portable toilet heavy and reliably avoiding interference with the nozzle and guide plate of the cleaning device. It is possible to achieve the effect.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a portable toilet equipped with a cleaning device according to the present invention. On a seat surface 1a of a wooden chair member 1, a cleaning device 2 for cleaning the hips is fixed at the rear end. In addition, the toilet seat 4 is swingably supported with respect to the front portion of the cleaning device 2 via a hinge 3 so that the toilet seat 4 can take two positions, a flat position shown in the figure and an upright position. Yes.

  In the figure, reference numeral 5 denotes a cushioning seat for a user to sit when using the portable toilet as a chair. The seat 5 covers the upper surface of the toilet seat 4 and is a horizontal position where the toilet seat 4 is seated. As shown in the figure, the seat part is erected in a folded state through the support member 5a, so that when it is used, the seat part 1 comes into contact with the back part 1b of the chair member 1 so as to function as a cushioned backrest. It is configured.

  In the figure, 2a is an operation panel for selecting the function of the cleaning device 2, and 1e and 1f are armrests. As can be seen from the figure, the armrest 1f on one side is configured to be short, and this is because a person with a physical disability supports the body from the short armrest 1f side to the armrest 1f while shortening it to the portable toilet. Is designed so that it can be easily slid.

  Next, a description will be given focusing on the inside of the opening 4a opened in the center of the toilet seat 4. A seat opening 1d for the bucket 6 larger than the opening 4a is formed on the seat surface 1a of the chair member 1 below the toilet seat 4 while corresponding to the opening 4a. A step-like support surface 1c that supports a bucket 6 to be described later is formed at the periphery of the storage opening 1d, and the bucket 6 is placed on the chair member 1 by placing the flange 6a of the bucket 6 on the support surface 1c. It is comprised so that it may be supported by.

  In the figure, reference numeral 7 denotes a lid that covers the opening of the bucket 6, and this lid 7 plays a role of preventing odors and splashing of accumulated water when the bucket 6 is transported.

  Next, a nozzle 2b for cleaning the butt is provided on the opening 4a side of the cleaning device 2 so as to be able to take a retracted state and an extended state as shown in the figure. Below the nozzle 2b is a chair member. A guide plate 8 fixed to one seating surface 1a is provided. The guide plate 8 is provided below the nozzle 2b so that the cleaning water sprayed by the nozzle 2b for cleaning the nozzle 2b is surely guided into the bucket 6. Here, supplementing the cleaning of the nozzle 2b, in order to clean the nozzle 2b when the nozzle 2b is in the retracted state of the figure, the nozzle is directed from the nozzle 2b toward the upper wall of the cleaning chamber 2c located above the nozzle 2b. The nozzle 2b is sprayed with cleaning water by itself, and the nozzle 2b is cleaned with the rebounding cleaning water. The cleaning water that has cleaned the nozzle 2b falls on the upper surface of the guide plate 8, and the guide plate 8 It is transmitted and falls into the bucket 6.

  2 is a perspective view similar to FIG. 1, except that the cleaning device 2, the toilet seat 4 and the seat portion 5 are removed so that the seat surface 1a and the bucket 6 of the chair member 1 can be easily confirmed. The same applies to the following, but the same components as those in FIG.

  In FIG. 2, since the toilet seat 4 is removed, a substantially U-shaped handle 9 for taking out and transporting the bucket 6 to a position corresponding to the front lower portion of the toilet seat 4 is stored on the front side of the bucket 6. It can be seen that the handle 9 is swingably attached to the bucket 6 so as to straddle the side upper part of the bucket 6. Note that the state of the handle 9 shown in the figure is a state in which the handle 9 is in a normal storage position that is horizontal.

  Next, in the normal storage state of the bucket 6 shown in the figure, the gap 10 is continuously provided from the center of the bucket 6 to the entire circumference around the front side. This means that the bucket opening 1d formed on the seat surface 1a is longer than the longitudinal length of the bucket 6 in the longitudinal direction, and the bucket 6 extends in the longitudinal direction through the storage opening 1d. It is configured to be slidable. Needless to say, the flange 6a of the bucket 6 is placed on the support surface 1c to ensure this sliding.

  Next, the reason why the bucket 6 is allowed to slide will be described with reference to FIG. FIG. 3 is a side view using a partial cross-sectional view. As is apparent from this figure, the bucket 6 can reliably trap the cleaning water for cleaning the nozzle 2b described above in a normal storage state. Thus, the guide plate 8 and the rear end of the bucket 6 are arranged so as to overlap each other by a length L below the guide plate 8 described above. As a result, the cleaning water for cleaning the nozzle 2 b falling on the guide plate 8 can be surely dropped into the bucket 6. Therefore, the rear end (left side in the figure) of the bucket 6 is configured in such a way that the rear end is largely cut by the recess 6b so as to overlap the guide plate 8 as clearly shown in FIG.

  Next, in the present invention, in order to facilitate the removal of the bucket 6, the handle 9 is disposed in the retracted state so as to be positioned on the front side as shown in the figure. I will explain the point of view.

  In general, a gap L1 exists between the upper surface of the bucket 6 and the lower side of the toilet seat 4, but in the present invention, the gap L1 is integrally extended from the flange 6a of the bucket so as to be integrally formed by the shielding portion 6c. It is configured to shield. This prevents small water or accumulated water in the bucket 6 from splashing from the gap L1 and adhering to the grip portion 9b of the handle 9. By this shielding part 6c, the bucket 6 can be taken out cleanly, and uncomfortable feelings such as caregivers can be eliminated.

  Further, when the toilet seat 4 is set to the flat position shown in the drawing, the shielding portion 6c is configured to be in close contact with the lower surface of the toilet seat 4 so that the toilet seat 4 is pressed into FIG. As can be seen from the perspective view of the bucket 6 shown in the figure, the shielding portion 6c is long except for the rear end portion. It works effectively for the problem of sound during use that has been a burden on the user, reduces sound leakage, and does not have a lot of anxiety and discomfort even in a usage environment that is not a toilet booth It is also possible to produce an excellent effect that it can be added.

  Next, a method for taking out and storing the bucket 6 will be described in detail with reference to FIG. First, the case where the bucket 6 is taken out after use is described. In order to take out the bucket 6 after adding the service, as shown in FIG. 4a, first, the toilet seat 4 is swung in an upright state, and then the handle 9b of the exposed handle 9 is lifted while moving in the direction of the arrow A, that is, naturally. When the handle 9 is lifted while pulling in the direction of the user, the bucket 6 easily moves in the direction A (left side in the figure), and the overlap with the guide plate 8 interferes and the bucket 6 It becomes possible to take out upward.

  Here, the viewpoint to which the present invention is further devised will be described. That is, when the bucket 6 is slid in the direction A, the bucket 6 has a certain weight because it contains excrement in addition to the pooled water, but in the present invention, the chair member 1 is slid so that it can be easily slid. A plurality of protrusions 6d are integrally formed on the lower surface of the flange 6a of the bucket 6 that abuts on the support surface 1c to reduce the contact area and lower the sliding resistance, thereby resisting the weight of the portable toilet. Only the bucket 6 is easily slid to the user side. Here, the bucket 6 is provided with the protrusion 6d, but the protrusion may be formed on the support surface 1c side of the chair member 1, and is not limited to the protrusion, but a low friction tape or a low friction resin member. Needless to say, it is sufficient to apply a low-friction process such as using a roller or using a roller.

  In the state where the bucket 6 has moved forward, the rear end of the bucket 6 can be taken out without interfering with the guide plate 8 by lifting it up through the handle 9 without needing to introduce it as FIG. 4b. Is.

  Next, the procedure for storing the bucket 6 in the portable toilet will be described. The bucket 6 is stored in such a manner that after the bucket 6 that becomes heavier when the reservoir water is contained is placed on the chair member 1 and the like, the bucket 6 is moved backward in a direction away from yourself, which is a direction in which force is difficult to enter. Become work. Thereby, both can be overlapped in the retracted state while avoiding interference between the guide plate 8 and the rear end of the bucket 6. However, this work can be difficult if it is performed by an elderly person or a person with a physical disability, even if it is a healthy person. In the present invention, the storage operation of the bucket 6 is also delicately devised.

  The operation for storing the bucket 6 will be described below with reference to FIG. 4c. The bucket 6 is placed on the chair member 1 by allowing the bucket 6 to pass through the storage opening 1d of the chair member 1 and the flange 6a of the bucket 6 abut on the support surface 1c in the state where the toilet seat 4 is raised. At this point in time, the guide plate 8 and the recess 6b of the bucket 6 do not overlap or are slightly overlapped if they are stored rearward with some consideration. In this state, since the bucket 6 is not in the complete storage position, it is not preferable that the nozzle 2a be cleaned or used in this state.

  In the present invention, in this state, as shown in the drawing, it is one idea to prevent the handle 9 from being in the normal horizontal storage position. As a result, it is possible to easily determine that the bucket 6 is not in the normal storage state because the handle 9 is not in the normal storage state or the toilet seat 4 is not in the normal flat position. Therefore, it is possible to reliably prevent the bucket 6 from being used in an abnormal storage state. In addition, if the bucket 6 is found to be in an abnormal state, the user can again hold the handle 9 and move it backward while lifting the bucket. By pushing the tilted handle 9 backward, the bucket 6 can be easily slid. In this case, it is not necessary to lift the bucket 6 or move the heavy bucket 6 away from the body. Therefore, the bucket 6 can be brought into a normal storage state very easily, and the guide plate 8 and the bucket 6 can be reliably overlapped.

  Further, in the present invention, a delicate device is applied, and when the bucket 6 as shown in the figure is not in a normal storage state, the toilet seat 4 is pressed from above so that the toilet seat 4 is in a normal position. Alternatively, simply by sitting on the toilet seat 4 to add work, the contact portion 4a provided on the toilet seat 4 presses the handle 9 downward while contacting the handle 9. As a result, the handle 9 receives the downward force, and the curved curved surface portion 9c formed on the handle 9 comes into contact with the inclined surface 1g formed on the support surface 1c of the chair member 1, and guides the inclined surface 1g. As a result, the bucket 6 moves to the right side of the drawing, which is the rear side, and the bucket 6 automatically slides to a proper position where the guide plate 8 and the rear end of the bucket 6 are surely overlapped. As is clear from the above, the bucket can be stored without worrying about the painful and cumbersome work of overlapping the guide plate 8 and the bucket 6.

  Furthermore, in the present invention, in order to reduce the weight of the sliding operation of the heavy bucket 6, it is devised to reduce the frictional force generated between the bucket 6 and the support surface 1 c, so that the operating force can be reduced. However, if the handle 9 is deformed, a sufficient sliding force cannot be secured, but it is not necessary to increase the strength of the handle 9 by reducing the frictional force. The effect that it is not necessary to make it heavy can be produced. Specifically, a plurality of protrusions 6d are provided on the lower surface of the flange 6a of the bucket 6 to make point contact with the support surface 1c.

  Finally, details of the bucket 6 will be described with reference to FIG. The contents described in the previous description are given the same reference numerals and are omitted. This bucket 6 is a silencing bucket, and as shown in FIG. 5b, a convex portion 6e is formed at a portion where small water abuts. The convex portion 6e suppresses vibration by increasing the rigidity of the convex portion. In the present invention, the shape of the convex portion 6e is optimized in detail.

  Specifically, if the convex portion 6e is simply formed in a convex shape, the surface strength cannot be increased unless the convex portion is protruded to a large convex shape, so that the generation of sound cannot be reduced. There is a problem in that a large amount of falling sound is generated because the water is diverted by the convex portion and falls into the accumulated water. In the present invention, first, the first shelf 6f is formed, and the second projection 6g is formed in the center of the shelf 6f so that the upper portion is triangular and widens downward. Configured. By configuring in this way, the surface rigidity can be increased without raising the convex portion 6e so much, so that the impact sound due to the collision of small water and the small water are divided into two at the top of the convex portion. The concentrated sound does not fall in the bucket 6, and the falling sound is greatly reduced because the film 6 is dispersed in the accumulated water and dropped in such a manner that the film is applied to the convex portion 6e.

  In the figure, 6h is a draining groove formed in a concave shape on the upper surface of the flange 6a so as to substantially correspond to the grip portion 9b of the handle 9. Although the shielding member 6c is provided, if the seating state of the toilet seat 4 is inadequate, it is undeniable that small water or the like drips on the grip portion 9b side even if it gets over the shielding member 6c. . The draining groove 9h is accumulated in advance in the draining groove 9h so that the small water does not touch the grip portion 9b even if there is small water dripping over the shielding member 6c. Is. Thus, even in the present case in which the grip portion 9b is securely stored on the front side, the user can carry the bucket 6 by gripping the grip portion 9b without causing concern about dirt.
