Description

  The present invention relates to a portable toilet.

  For example, Japanese Patent Laying-Open Nos. 2005-304694 and 2014-64601 disclose a furniture-like portable toilet in which a sewage receptacle, a bucket, a toilet seat, and the like are arranged on a frame formed of wood. Here, the frame is also referred to as a toilet outer shell. The sewage catcher is called a toilet seat catcher or a catch plate. The bucket is also called a filth pot.

JP 2005-304694 A JP 2014-64601 A

  So-called furniture-like portable toilets have a sewage tray placed on a wooden frame, but the scattered urine adheres to the wooden frame, causing odors to the frame and the frame to rot. There was a case.

  The portable toilet proposed here includes a wooden frame and a resin tray. The frame has a tray placement section for placing the tray at a predetermined position. The front part of the tray placed on the tray placing part protrudes ahead of the frame body in plan view. In this case, urine hardly adheres to the frame.

  In this case, for example, the tray has a bucket placement portion for placing the bucket at a predetermined position, and the frame body is made of a front material arranged in front of the outer peripheral surface of the bucket placed on the tray. You may have. And it is good for the forefront part of an internal peripheral surface in the upper edge of a bucket to have come out ahead of the front material among frame bodies in planar view. With this configuration, for example, the inner peripheral surface of the bucket is widened forward, and urine is unlikely to leak in front of the portable toilet.

  Further, the frame body may include a pressing portion that hits the upper surface of the rear portion of the tray placed on the tray placement portion. With this structure, the rear portion of the tray can be prevented from floating. Further, the upper front portion of the tray may include an inclined surface that is inclined downward toward the front and a step that is recessed backward from the lower edge of the inclined surface. In this case, since there is an inclined surface that is inclined forward in the upper part of the front surface of the tray and a step that is recessed backward from the lower edge of the inclined surface, urine that travels on the inclined surface easily falls from the lower edge of the inclined surface to the floor. For this reason, urine leaking from the front surface of the tray is not easily transmitted to the frame. Moreover, you may provide the decorative board which is arrange | positioned in the front side of the front material, and the intermediate part of the left-right direction curves ahead, and was equipped with the inclination part which inclined back as it went to the lower part from the upper part.

  The tray may include a lower member placed on the tray placing portion and an upper member placed on the lower member. The upper member may include a bucket placement portion for placing the bucket at a predetermined position, and a receiving portion extending around the bucket placed on the bucket placement portion. In this case, when spilled water is spilled, only the upper member can be cleaned, so cleaning is easy.

  Further, the front part of the lower member may have a protrusion protruding upward on the inner side of the upper edge in plan view. A front portion of the upper member may have a contact portion that hits the protrusion. By providing the protrusion, the upper member can be stably supported. The protrusion may have a structure in which the bottom surface of the lower member is raised upward. According to this structure, since the upper surface of a lower member continues, it is easy to wipe and cleaning becomes easy. Further, the upper edge of the front portion of the lower member may hit the upper member.

  The tray may include a bucket housing portion that covers the outside of the bucket placed on the bucket placement portion. This makes it difficult for the bucket to be seen on the exterior of the portable toilet and improves the appearance of the portable toilet. When the tray is composed of an upper member and a lower member, the lower member may include a bucket housing portion that covers the outer side of the bucket placed on the bucket placement portion.

The second rear face member 12d2 is disposed in the lower part of the rear part of the left face member 12b and the right face member 12c.

<Tray placement unit 50>
The frame body 12 has a tray mounting portion 50 for mounting the tray 14 at a predetermined position. In this embodiment, as shown in FIG. 2, the tray mounting portion 50 is provided on the upper surface of each member of the front member 12a, the left and right support plates 12b5 and 12c5, and the first rear member 12d1.

<Presser member 12e>
The frame body 12 may include a pressing portion that hits the upper surface of the rear portion 14 b of the tray 14 placed on the tray placement portion 50. In this embodiment, a pressing member 12e is disposed above the rear surface material 12d (here, the first rear surface material 12d1) as a pressing portion that hits the upper surface of the rear portion 14b of the tray 14. As shown in FIG. 3, the pressing member 12 e protrudes inward from the left and right face members 12 b and 12 c. As shown in FIG. 1, the pressing member 12 e is disposed immediately above the upper surface of the rear portion 14 b of the tray 14 mounted on the tray mounting portion 50. When the front portion 14a of the tray 14 is pushed down with respect to the frame body 12, the upper surface of the rear portion 14b of the tray 14 contacts the pressing member 12e. For this reason, the front part 14a of the tray 14 mounted on the tray mounting part 50 is not pushed down.

  For example, when a user who needs care is transferred from the bed to the portable toilet 10, a state in which the user sits with respect to the toilet seat 24 in a position shifted forward from an appropriate position may occur. The tray 14 is provided with a toilet seat 24, and the weight of the user is applied to the tray 14 through the toilet seat 24. In this portable toilet 10, the tray 14 protrudes ahead of the front material 12a. For this reason, when the weight of the user is applied to the front part 14a of the tray 14, the front part 12a of the tray 14 is pushed down with the front member 12a of the frame 12 as a fulcrum, and the rear part 14b of the tray 14 is pushed. The force acts to lift up. In this embodiment, the frame body 12 is provided with a pressing member 12e on the rear portion 14b of the tray 14 placed on the tray placement portion 50. For this reason, even if the force which raises the rear part 14b of the tray 14 acts, the rear part 14b of the tray 14 contacts the pressing member 12e. In this way, when the pressing member 12e is in contact, the front portion 14a of the tray 14 is not greatly pushed down.

<Tray 14>
The tray 14 is made of resin and has a bucket mounting portion 14c for mounting the bucket 16 at a predetermined position. The tray 14 is placed on the tray placement unit 50 of the frame body 12. The front part 14a of the tray 14 placed on the tray placing part 50 protrudes in front of the front member 12a of the frame 12 in plan view. Thus, since the tray 14 protrudes forward from the front member 12a, urine is hardly applied to the front member 12a. In this respect, the front portion 14a of the tray 14 protrudes forward by 5 mm or more, preferably 1 cm or more, from the foremost portion 12a2 of the front member 12a (in this embodiment, the upper front edge (see FIG. 9)). Good. In order for the tray 14 to be stably supported by the front member 12a, the distance that the tray 14 protrudes forward from the front member 12a is, for example, 8 cm or less, preferably 5 cm or less. In this embodiment, the front portion 14a of the tray 14 protrudes approximately 3 cm forward from the foremost portion 12a2 of the front member 12a. Further, as shown in FIG. 9, the upper portion of the front surface of the tray 14 includes an inclined surface 14d that is inclined downward toward the front, and a step 14d1 that is recessed backward from the lower edge of the inclined surface 14d. In this case, urine traveling along the inclined surface 14d tends to fall from the lower edge of the inclined surface 14d to the floor. For this reason, even when urine is transmitted through the front surface of the tray 14, urine is not easily applied to the front material 12 a of the frame 12. Moreover, the tray 14 is good to be provided with the bucket accommodating part 14e which covers the outer side of the bucket 16 mounted in the bucket mounting part 14c. Since the tray 14 covers the outside of the bucket 16, the appearance of the portable toilet 10 is improved.

  FIG. 6 is a perspective view of the tray 14. FIG. 7 is a perspective view of the tray 14 on which the bucket 16 is placed. FIG. 8 is a perspective view of the lower member 64. FIG. 9 is a vertical side view of the enlarged portable toilet 10 at the front of the frame 12 on which the tray 14 is placed. In FIG. 9, the bucket 16 placed on the tray 14 is indicated by a two-dot chain line. 10 is a cross-sectional front view of the tray 14 and is a cross-sectional view taken along the line XX of FIG. In this embodiment, the tray 14 includes an upper member 62 and a lower member 64 as shown in FIG.

<Upper member 62>
As shown in FIGS. 6 and 7, the upper member 62 extends around the bucket mounting portion 14c for mounting the bucket 16 in a predetermined position, and the bucket 16 mounted on the bucket mounting portion 14c. Receiving portion 62b. In this embodiment, the upper member 62 of the tray 14 has an opening 62c in which the bucket 16 is mounted at the center. An inner wall 62d that rises upward is provided around the opening 62c. The bucket mounting portion 14c is provided on the upper edge of the inner wall 62d. A recess 62e is provided on the outer periphery of the inner wall 62d. An outer wall 62f that rises upward is provided on the outer periphery of the recess 62e. There is a step on the outer wall 62f, and a mounting portion 62g on which the toilet seat 24 is mounted is provided.

  Thus, the upper member 62 is provided with the receiving portion 62 b that receives the urine around the bucket 16. The upper member 62 functions as a so-called “receiving plate”. The upper member 62 is put on the lower member 64. As shown in FIG. 9, the front portion 62 a of the upper member 62 includes an outer edge portion 62 h that is bent outward and extends downward. A rib 62i is provided between the outer wall 62f and the outer edge portion 62h extending downward. Further, as shown in FIG. 6, an air duct connection port 62 n connected to the deodorizing device 28 is provided in the rear portion 62 m of the upper member 62.

<Lower member 64>
As shown in FIG. 1, the lower member 64 includes a bucket housing portion 14 e. In this embodiment, the bucket housing portion 14 e covers the outside of the bucket 16 placed on the bucket placement portion 14 c and surrounds the bottom of the bucket 16. That is, the outer peripheral surface 16 a of the bucket 16 is generally surrounded by the lower member 64 of the tray 14. For this reason, urine overflowing inside the lower member 64 by being transmitted through the outer peripheral surface 16a of the bucket 16 is received by the bucket accommodating portion 14e. By this bucket accommodating portion 14e, the lower member 64 functions as a so-called “sewage receiver”.

  Further, the lower member 64 is placed on the tray placing portion 50 provided in the frame body 12. As shown in FIG. 9, on the lower surface of the front portion 64a of the lower member 64, there is a surface 64b that is placed on the front member 12a of the frame 12, and the rear surface (inner surface) of the front member 12a from the surface 64b. And a surface 64c extending downward along the surface.

  Further, the front portion 64a of the lower member 64 has a protrusion 64f protruding upward as shown in FIG. The protrusion 64f is provided on the inner side (rear side) of the upper edge 64e of the front portion 64a in plan view. On the other hand, as shown in FIG. 9, the back surface of the front portion 62a of the upper member 62 has a contact portion 62j that hits the protrusion 64f. A front portion 62 a of the upper member 62 is supported by a protrusion 64 f of the lower member 64. Thus, in this embodiment, the upper member 62 is stably supported by the lower member 64 in the front portion 14a of the tray 14, and the required strength is ensured. Further, by providing the above-described protrusion 64f as a support structure for the front portion 14a of the tray 14, it is possible to prevent a load from being concentrated on the upper edge 64e of the front portion 64a of the lower member 64. Further, in this embodiment, a protrusion 64f is provided in which the bottom surface 64g of the lower member 64 is raised upward. Since the bottom surface 64g of the lower member 64 is raised and the protrusion 64f is provided, the number of parts does not increase. Furthermore, since the upper surface of the lower member 64 provided with the protrusions 64f is a continuous surface, the upper surface of the lower member 64 is easy to wipe and easy to clean.

  The upper edge 64e of the front portion 64a of the lower member 64 is in contact with the upper member 62. When the upper edge 64 e of the front portion 64 a of the lower member 64 is in contact with the upper member 62, the load acting on the upper member 62 is supported by the lower member 64. In this embodiment, in the front portion 14 a of the tray 14, the upper edge 64 e of the lower member 64 hits the rib 62 i provided on the back surface (lower surface) of the outer edge portion 62 h of the upper member 62. As a result, the load acting on the upper member 62 is supported by the lower member 64, so that the front portion 14a of the tray 14 is not easily deformed.

  Moreover, in this embodiment, the front upper part of the tray 14 is provided with the inclined surface 14d inclined downward as it goes to the front. And the level | step difference 14d1 dented back from the lower edge of this inclined surface 14d is provided. In this embodiment, the outer edge portion 62 h of the upper member 62 covers the upper edge 64 e of the front portion 64 a of the lower member 64 on the front surface of the tray 14. The front surface 62h1 of the outer edge portion 62h is inclined forward as it goes from the upper part to the lower part. The upper edge 64e of the lower member 64 is fitted inside the lower edge of the front surface 62h1, and a step 14d1 that is recessed backward from the lower edge of the front surface 62h1 is formed. For this reason, when the urine overflowing forward from the tray 14 travels along the front surface 62h1 of the outer edge portion 62h of the upper member 62, it falls from the lower edge of the front surface 62h1 of the outer edge portion 62h to the floor. For this reason, it is difficult to be transmitted to the lower member 64. Further, in this embodiment, the front surface 64h of the lower member 64 is inclined backward as it goes downward from the upper edge 64e of the front portion 64a. For this reason, even when urine travels along the front surface 64h of the lower member 64, urine tends to fall downward from the front surface 64h of the lower member 64 in the middle thereof. Furthermore, the lower end of the front surface 64h of the lower member 64 protrudes ahead of the front material 12a. In this embodiment, the lower end of the front surface 64h of the lower member 64 protrudes 5 mm or more (about 1 cm) before the front material 12a. For this reason, urine that travels on the front surface 64 h of the lower member 64 does not easily reach the front material 12 a of the frame body 12, and urine does not easily adhere to the frame body 12 on the front surface of the portable toilet 10.

  As shown in FIG. 10, the peripheral edge 62 k of the upper member 62 covers the upper edge 64 i of the lower member 64 on both the left and right sides of the tray 14. For this reason, the deformation of the upper member 62 and the lower member 64 is suppressed to be small, and the deformation of the tray 14 is suppressed to be small as a whole. Further, a step 64j is provided on the lower member 64 so as to hit the back surface of the placement portion 62g of the upper member 62 on which the toilet seat 24 is placed. The back surface (lower surface) of the step 64j of the lower member 64 is placed on support plates 12b5 and 12c5 (see FIG. 3) provided inside the left surface material 12b and the right surface material 12c. As described above, the lower member 64 is placed on the tray placing portion 50 provided on the frame body 12 in the front-rear direction and the left-right direction. A placement portion 62 g of the upper member 62 on which the toilet seat 24 is placed is supported by the lower member 64 and the frame body 12.

  Further, in the rear portion 14b of the tray 14, as shown in FIGS. 7 and 8, the rear portion 64k of the upper member 62 covers the rear portion 64k of the lower member 64. As shown in FIG. 1, the rear portion 62m of the upper member 62 and the rear portion 64k of the lower member 64 are stacked one above the other and placed on the first rear member 12d1 of the frame 12, and the upper surface is pressed by the pressing member 12e. It has been. The portion is lifted when the front portion of the tray 14 receives a load on the lower side, and presses against the pressing member 12e. In this embodiment, since the rear part 62m of the upper member 62 and the rear part 64k of the lower member 64 are overlapped, the required strength is ensured. Further, a deodorizing device holding portion 64m for holding the deodorizing device 28 is provided at the rear portion 64k of the lower member 64 corresponding to the duct connection port 62n of the upper member 62.

  Thus, in this portable toilet 10, the front part 14a of the tray 14 placed on the tray placing part 50 protrudes in front of the front member 12a of the frame 12 in a plan view. Is hard to get dirty. In relation to the front of the front surface 12a of the frame body 12a, the rear portion of the tray 14 is prevented from being lifted by the pressing portion (the pressing member 12e in the above-described embodiment) provided on the frame body 12. Has been. Various improvements have been made to improve the strength of the front portion of the tray 14. In addition, the front surface of the portable toilet 10 has a structure in which urine does not easily leak, and the convenience of the user and the caregiver is achieved.

  For example, in this portable toilet 10, a bucket 16 is placed on a tray 14 placed on a frame 12 as shown in FIG. The front member 12 a is disposed in front of the outer peripheral surface of the bucket 16. Specifically, the front member 12 a is more than the outer peripheral surface 16 a of the bucket 16 in the intermediate portion in the vertical direction of the bucket 16 among the outer peripheral surfaces of the bucket 16 disposed at a predetermined position with respect to the frame body 12. It is arranged in the front. In the form shown in FIG. 1, the outer peripheral surface 16 a of the bucket 16 is surrounded by a lower member 64 of the tray 14 to be described later in the middle portion of the bucket 16 in the vertical direction. The front member 12a is disposed in front of the lower member 64. In this embodiment, the front member 12a is a plate-like member, but is not limited to a plate-like member. The front member 12a is a constituent member of the frame 12 and is spanned between the front part of the left face member 12b and the front part of the right face member 12c. What is necessary is just the member arrange | positioned ahead rather than the outer peripheral surface of the bucket 16 arrange | positioned in the position.

  In this portable toilet 10, as shown in FIG. 1, the foremost part 16b of the inner peripheral surface of the bucket 16 at the upper edge of the bucket 16 protrudes ahead of the front member 12a of the frame 12 in plan view. . More specifically, FIG. 1 is a cross-sectional view taken along the central portion in the left-right direction of the portable toilet 10, and, as shown in FIG. The foremost portion 16b of the frame body 12 protrudes in front of the front member 12a of the frame body 12. More specifically, the forefront portion 16b of the inner peripheral surface of the bucket 16 may protrude forward from the upper front edge of the front member 12a of the frame body 12. In this case, the front member 12a is based on the foremost part 12a2. For example, the foremost part 16b of the bucket 16 may protrude forward by 5 mm or more, preferably 1 cm or more than the foremost part 12a2 of the front surface member 12a.

  Here, FIG. 11 is a plan view of the portable toilet 10, and a user sitting on the portable toilet 10 in a normal use posture is indicated by a virtual line H. FIG. In the portable toilet 10, as shown in FIG. 11, a space S <b> 1 that reaches the frontmost portion 16 b of the inner peripheral surface of the upper edge of the bucket 16 can be secured widely with respect to the groin h <b> 1 of the user H sitting on the portable toilet 10. . Since the space S1 reaching the forefront portion 16b of the inner peripheral surface at the upper edge of the bucket 16 is secured widely, urine is less likely to leak forward than the upper edge of the bucket 16. As for this point, since a space S1 reaching the forefront portion 16b of the inner peripheral surface at the upper edge of the bucket 16 is widely secured, the opening 24a of the toilet seat 24 disposed on the bucket 16 is also secured widely forward. Can be done. For this reason, scattering from the outside of the opening of the toilet seat 24 can be reduced.

  Further, as shown in FIG. 1, the front member 12 a of the frame body 12 is located behind the frontmost portion 16 b of the inner peripheral surface of the bucket 16 at the upper edge of the bucket 16. Therefore, a space S <b> 2 that has entered the interior of the portable toilet 10 larger than the front edge of the toilet seat 24 can be secured on the front surface of the portable toilet 10 (in other words, in front of the front surface member 12 a of the frame 12). By securing such a space S <b> 2, a user sitting in the portable toilet 10 can draw his / her legs deeper near his / her center of gravity and can easily move up from the portable toilet 10. Moreover, when such a space S2 is secured, when assistance is required when the user stands up from the portable toilet 10 or transfers to the portable toilet 10, this space S2 is also provided to the assistant. The foot can be stepped deeply under the portable toilet 10. Thereby, since the center of gravity of the assistant can be brought close to the center of gravity of the user sitting on the portable toilet 10, the burden on the assistant can be greatly reduced.

  Although one embodiment of the portable toilet 10 has been described above, the portable toilet proposed here is not limited to the above-described embodiment unless specifically mentioned.

  For example, the specific structures of the frame 12 and the tray 14 are not limited to the above-described embodiment unless otherwise specified.

  For example, the tray 14 exemplifies a form constituted by the upper member 62 and the lower member 64. However, the tray 14 may include a bucket mounting portion 14c. For example, the lower member 64 may include the lower member 64. It is not necessary. That is, the tray 14 may be configured by a member called a so-called receiving plate. FIG. 12 is a cross-sectional view showing a portable toilet 10A according to another embodiment. In this portable toilet 10 </ b> A, the tray 14 has a structure according to the above-described upper member 62, and is directly placed on the tray placing portion 50 of the frame 12. As shown in FIG. 12, the tray 14 has an inclined surface 14 d that conforms to the front surface 62 h 1 (see FIG. 1) of the upper member 62, and may be placed on the front material 12 a of the frame 12.

  In the form shown in FIG. 12, the portable toilet 10 </ b> A is separate from the tray 14 and includes a decorative plate 66. The decorative plate 66 is disposed on the front side of the frame body 12 and includes an inclined surface 66a that is curved forward at the middle portion in the left-right direction and inclined backward as it goes from the upper part to the lower part. The decorative plate 66 can conceal the bucket 16 and the lower part of the tray 14 on the front surface of the portable toilet 10A, and can prevent urine from adhering to the frame body 12 (the front material 12a of the frame body 12). The decorative board 66 may be attached to the frame body 12 (for example, the front material 12a, the left surface material 12b, the right surface material 12c, etc.). Further, the decorative plate 66 may be attached to the tray 14. Further, the decorative plate 66 may be attached when the tray 14 includes the upper member 62 and the lower member 64 as described above. Moreover, since the decorative board 66 is provided with the inclined surface 66a inclined backward as it goes from the upper part to the lower part, a wide space under the foot can be secured.

  As described above, the invention proposed here is used for a portable toilet.
