Description

  The present invention relates to a portable toilet (movable simple toilet) having a pivotable toilet seat, and particularly in a portable toilet having a substantially rectangular outer shape on a flat surface portion, both sides of the front end of the portable toilet are provided on both sides of the toilet seat. The present invention relates to a portable toilet in which the degree of freedom of a user's seating position is increased by curving and retreating so as to protrude rearward from the tip of the opening.

  2. Description of the Related Art In recent years, portable toilets (mobile simple toilets) have become widespread for elderly people and physically handicapped people to excrete in living rooms.

  By the way, in recent years, portable toilets are often provided with armrests and backrests in consideration of use by elderly people and physically disabled people. For this reason, the flat part of the stool on which the toilet seat is placed is often formed in a substantially rectangular shape as a whole so that the armrest and the backrest can be supported.

  Further, in the portable toilet having the substantially flat plane portion as described above, if the outer shape of the toilet seat is an O shape that is substantially similar to the opening of the toilet seat, the O-shaped toilet seat has an O between the substantially square plane portion. A gap or a step is formed along the outer edge of the shaped toilet seat, and the gap or the step is arranged so as to cross the back side of the thigh portion of the seated user in an oblique direction. For this reason, in a portable toilet with an O-shaped toilet seat, if the user moves the leg after sitting on the toilet seat, the skin on the back of the thigh is placed between the toilet seat and the flat surface of the toilet body. There is a problem of being injured by being caught in the created gaps and steps.

  For this reason, in a portable toilet having a substantially square plane portion, Japanese Patent Application Laid-Open No. 2005-0003287 (Patent Document 1), Japanese Patent Application Laid-Open No. 2010-240165 (Patent Document 2), Japanese Patent Application Laid-Open No. 2012-152256 (Patent Document 3). ), The outer shape of the toilet seat is also substantially rectangular, so that the gaps and steps created between the toilet seat and the flat surface of the toilet body are oblique to the back side of the user's thigh. The use of toilet seats that do not cross over is increasing.

  Thus, in recent portable toilets, the plane portion has a substantially rectangular outer shape, and a type in which a substantially rectangular toilet seat is attached is becoming mainstream. However, the portable toilet having a substantially rectangular flat surface portion as described above has a front end portion of the portable toilet projecting forward compared to a stationary toilet with a flat surface portion having an O shape. When trying to sit behind the toilet seat, the back side of the knee hits the front end of the portable toilet relatively on the front side, and there was a problem that it was not possible to sit down deeply.

  In addition, as described above, since the armrest is usually attached to the portable toilet, the front end portion of the portable toilet is arranged so that the back side of the user's knee does not hit the front end portion of the portable toilet relatively on the front side. When both ends of the toilet are retracted backward from the toilet body, there is a problem in that there is no space for attaching a support column for supporting an armrest in the flat part of the portable toilet.

  Therefore, the present invention provides a portable toilet having a substantially rectangular outer shape on a flat surface, and a space for attaching an armrest post to the flat surface portion of the toilet main body is secured, and the front end of the toilet main body is further seated. It is an object of the present invention to provide a portable toilet that does not hinder free movement of legs and allows a user to sit deeply behind the toilet seat.

  In addition, the present invention prevents the user's legs from being caught by eliminating protrusions and steps such as ribs from the surface of the toilet body while ensuring the necessary strength, It is an object of the present invention to provide a portable toilet in which the degree of freedom of movement of the legs is increased, and as a result, the user can stand up from the portable toilet and sit on the portable toilet with less movement.

  The present inventors have provided a rotatable toilet seat, and as a result of earnestly examining the shape and arrangement of a portable toilet having a substantially rectangular outer shape, the outer shape of the flat portion of the toilet main body is substantially reduced. After securing the space for placing the armrest struts by making it square and receding by curving both sides of the front end of the toilet body so that it protrudes backward from the tip of the toilet seat opening Thus, the user can sit deeply behind the toilet seat, and the present invention has been completed.

  Specifically, according to the present invention, the toilet main body having an upper surface having a first opening defined by an edge wall, the second opening having a closed periphery, and the upper surface. A toilet seat pivotably attached to the upper portion of the toilet seat, and the upper surface of the toilet body is located outside the upper surface of the toilet seat when the toilet seat is placed on the upper surface of the toilet body. A first side end extending substantially linearly from the end of the first toilet body located rearward of the front end of the opening to the rear of the upper surface, and the upper surface opposite to the first side end A second side end extending substantially linearly from the end of the second toilet body located rearward of the front end of the second opening of the toilet seat to the rear of the upper surface, and the toilet seat From the first end to the second end via the toilet body protrusion located in front of the tip of the second opening. And a toilet main body front portion extending portable toilet is provided.

  That is, the portable toilet of the present invention includes a toilet seat having an opening that is closed around the periphery. The toilet main body of the portable toilet of the present invention has a toilet seat placed on the upper surface of the toilet main body from the end of the toilet main body located behind the upper end of the toilet seat and outside the top of the toilet seat. It has the 1st and 2nd side edge part extended substantially linearly to the rear part of the toilet body part. The toilet body has a toilet body protrusion that is positioned forward of the front end of the toilet seat opening, as opposed to the toilet body ends of the first and second side ends. The front part of the toilet part is formed with a front end part of the toilet body extending from the end part of the first toilet body to the end part of the second toilet body via the protruding part, and has a substantially rectangular shape as a whole. doing.

  Here, the portable toilet in the present invention means a portable toilet as described in Patent Documents 1 to 3, which is used for excretion of elderly people and physically disabled people in a room or the like. In addition to the portable toilets that are mainly made of resin materials, the concept of portable toilets, for example, outer frames and legs other than portable toilets, armrests, backrests, etc., are made of materials such as wood, So-called furniture-like portable toilets are also included.

  Further, in the present invention, the “side end portion” means an outline of a portable toilet that appears in a plan view and an end face that forms the outline. Further, “substantially straight” means a line segment connecting two separated points with a substantially shortest distance. If the distance is substantially the same as a straight line, not only a straight line with a strict meaning but also a little “ Curved lines that are bent in the shape of "" and curved lines that are slightly bent to draw large arcs are also included. For this reason, it is sufficient that most of the side end portion extends substantially in a straight line, and a bulge or the like is formed on a part of the side end portion to accommodate, for example, the leg column of the portable toilet body. Also good.

  Further, in the present invention, the "front part" means an area in the vicinity of the front of the toilet seat and portable toilet placed on the abdomen of the user when an adult user sits on the toilet seat, and "rear part" Means an area in the vicinity of the back of the toilet seat and the portable toilet placed on the back side of the user when an adult user sits on the toilet seat. Further, the “toilet body end” at the side end of the portable toilet substantially changes the direction of the side end extending in the longitudinal direction of the portable toilet to the front end of the toilet body extending in the width direction of the portable toilet. It means a corner portion, and the corner portion may be not only a corner portion but also a corner portion with an R.

  In addition, in general, a portable toilet can be made compact after securing a space for attaching a pair of armrests arranged substantially in parallel on a plane portion of the toilet body, so the first side end of the toilet body Is arranged substantially parallel to the second side end.

  Furthermore, the portable toilet of the present invention has a toilet body front end extending from the first toilet body end to the second toilet body end via the toilet body protrusion, and the front end is 1 has a first inflection point between the toilet body end and the toilet body protrusion, and a second inflection point between the second toilet body end and the toilet body protrusion. It is preferable that the curve part which it has is included. In the present invention, the “inflection point” is sufficient if the front end of the toilet body changes from a convex state toward the rear of the toilet body portion to a convex state toward the front of the toilet body portion, The changing part includes not only a point but also a straight line.

  Thus, the portable toilet of the present invention is curved and retracted so that both end areas of the front end of the toilet body are convex toward the back of the toilet body compared to the toilet body having a rectangular flat surface. Even if the user tries to sit behind the toilet seat of the portable toilet, the front end portion of the toilet body does not hit the back side of the user's knee and become an obstacle. For this reason, the user can easily sit deeply behind the toilet seat of the portable toilet of the present invention.

  Further, the portable toilet according to the present invention has a central portion of the front end of the toilet body that protrudes forward relative to both end areas of the front end, so that when the user sits deeply behind the toilet seat, the front end The toilet body protrusion of the part abuts on the inner side of both knees of the user and guides the user's legs to open. For this reason, the user can take a posture that allows for easy excretion, and in particular, in the case of male users, the genitals can be easily directed downward, so that the user's urination is at the tip of the toilet seat. And it becomes possible to eliminate scattering beyond the protruding part of the front end of the toilet body.

  For this reason, the toilet seat attached to the portable toilet of the present invention may include a front edge that is disposed substantially parallel to the front end of the toilet body when the toilet seat is placed on the upper surface of the toilet body. preferable.

  That is, if the front part or part of the front edge of the toilet seat is substantially the same shape as the front end part of the toilet body, both ends of the conventional front edge can be used even if the user tries to sit behind the toilet seat of the portable toilet. Compared to a toilet seat where the area has not been retracted, the front edge of the toilet body and the front edge of the toilet seat do not interfere with the back of the user's knee, and the leg fit when the user is seated Can be increased. In addition, if the front part or part of the front edge of the toilet seat is substantially the same shape as the front end part of the toilet body, the toilet body protrusion at the front end of the toilet body and the protrusion at the front edge of the toilet seat are used in cooperation. Since it abuts widely on the inside of both knees of the user, both legs of the user are smoothly opened.

  Further, the posture in which the user opens both legs allows the user to wipe the defecation from the front by himself without taking the middle / lower back posture after excretion. In addition, even if the user is an elderly person or care recipient who must be wiped by an attendant or caregiver, the attendant may wipe the user's defecation without holding the user. As a result, the burden on the attendant and the like can be greatly reduced.

  In the present invention, the curved portion of the front end portion of the toilet body includes a first curved portion that curves convexly toward the rear of the toilet body portion between the first toilet body end portion and the first inflection point, and a second Between the second inflection point and the second inflection point, a second curving portion that curves convexly toward the rear of the toilet main body, and between the first inflection point and the second inflection point And a third curved portion that is convexly curved toward the front of the toilet body.

  As described above, the curved portion of the both end areas of the toilet body front end is curved convexly toward the rear of the toilet body, and the curved portion of the central portion of the toilet body front end is directed to the front of the toilet body. When the user sits deeply behind the toilet seat, the shape of both end areas of the front end of the toilet body fits on the back of the user's knee so that the user's legs are gently And guide them to open their legs smoothly. Further, the shape of the front end portion of the toilet body described above is convenient as a mark of a position where the user places his / her leg when sitting on the toilet seat.

  The portable toilet of the present invention includes a toilet main body, and the toilet main body is a box having an upper opening, and the front surface is inclined downward from the opening edge of the opening toward the rear of the box. It is preferably divided into a box portion having a portion and an upper surface portion connected to the opening edge of the box portion.

  As a means for improving the strength of the toilet body against deformation, a method of providing folded ribs or reinforcing ribs on the opening edge or side surface of the toilet body, or arranging a panel on each surface of the toilet body, A method of making the portion a so-called box structure is known.

  However, the folding rib on the opening edge is a protrusion that protrudes outward from the toilet body due to its structure. Therefore, if the folding rib is provided on the toilet body, the user can put the leg in the portable toilet or near the portable toilet. It becomes an obstacle to catch a leg when moving. Therefore, in the present invention, by adopting a box structure that is advantageous for eliminating projections such as folded ribs, projections that may cause a user to hook a leg or the like, particularly from the front surface of the toilet body, The step is eliminated and the front surface of the toilet body is smooth.

  In general, if the toilet body portion has a box structure, the moldability and maintainability of the toilet body portion are reduced, so in the present invention, a so-called two-piece structure is adopted, and the toilet body portion is a box portion whose upper portion is opened, The above-mentioned problem is solved by using two parts including an upper surface connected to the opening edge of the opening by a screw or the like. Therefore, in the present invention, both the box part and the upper surface part can be molded as a resin-made integral molded product, and as a result, a low-cost and sturdy portable toilet can be provided.

  In the portable toilet of the present invention, since the front part of the box part is inclined from the opening edge of the opening to the lower part of the box part and to the rear, the user can place his / her foot under the front end part of the toilet body part. Alternatively, it is possible to draw it directly below or behind the front edge of the toilet seat. For this reason, in the portable toilet of the present invention, when the user stands up from the portable toilet and / or when sitting on the portable toilet, the weight shift is mainly only in the vertical direction, Easy seating on portable toilets.

  Furthermore, the portable toilet of the present invention preferably connects the outer surface of the box part flush with the outer surface of the upper surface part.

  In the portable toilet of the present invention, the shape of the front end portion of the toilet body is substantially the same as the front edge of the toilet seat in order to freely move both legs of the user seated on the toilet seat as described above. For this reason, when the outer surface of the box portion is connected flush with the outer surface of the upper surface portion, the front surface having substantially the same surface shape as the shape of the front edge of the toilet seat from the front end portion of the toilet body portion downward to the toilet body portion The part can be formed.

  As a result, if the outer surface of the box part is flush with the outer surface of the upper surface part, the protrusions and steps are removed from the front part of the toilet body part, and the front part of the toilet body part can be made a smoother shape. In addition, the protrusion at the center of the front edge of the toilet seat can be continuously formed from the front edge of the toilet seat to the front of the toilet body so that the user can sit deeply behind the toilet seat. In this case, it is possible to more smoothly promote the user to open the legs of both legs.

  In the present invention, the upper surface portion of the toilet body has a frame portion, a receiving portion that has a first opening defined by an edge wall and is detachably attached to the frame portion inside the frame portion. It is preferable to be divided into two.

  The upper surface of the toilet body supports the armrest and the backrest, and is connected to the box to improve the strength of the toilet body, support the toilet seat from below, and further define the first opening. It also functions to support the bucket suspended from the first wall through the edge wall. For this reason, in the upper surface of the toilet main body, in particular, the first opening and its peripheral part are easily contaminated by the excrement and dust of the user, and it is necessary to appropriately clean and clean.

  Therefore, in the present invention, the upper surface portion of the toilet body is divided into a receiving portion including the first opening and its peripheral portion and a frame portion that detachably supports the receiving portion, whereby the receiving portion is separated from the toilet body. It is separated from the section so that it can be easily cleaned outside the portable toilet. Therefore, if the receiving part has a structure that can be easily detached from the toilet body part, the toilet body part does not necessarily have to be separated into the frame part (upper surface part excluding the receiving part) and the box part. May be a so-called one-piece structure.

  In addition, the receiving portion is provided with a bowl-shaped groove around the first opening of the receiving portion, thereby preventing the excrement of the user from dripping or scattering to other parts of the toilet body. be able to. If the toilet seat or lid is pivotally attached to the receiving part, the toilet seat and lid can be removed from the toilet body at once using the receiving part, making it easier to clean the portable toilet. It becomes.

  Next, the characteristics of the toilet seat attached to the portable toilet of the present invention will be described. The toilet seat attached to the portable toilet of the present invention has a first side edge disposed substantially parallel to the first side end of the toilet body when the toilet seat is placed on the upper surface of the toilet body, and It is preferable to provide the 2nd side edge arrange | positioned substantially in parallel with the 2nd side edge part of a toilet main-body part.

  In the present invention, when the first and second side edges of the toilet seat are arranged substantially parallel to the first and second side edges of the toilet body, respectively, the toilet seat has a substantially rectangular shape. It can be formed on the outer side of the thigh of the user who is seated with a gap or step formed between the upper surface of the main body. For this reason, the toilet seat having the first and second side edges as described above is slanted on the back side of the user's thigh where the gap or step between the toilet seat and the upper surface of the toilet body is seated. Since it is possible to eliminate crossing in the direction, it eliminates the problem that the skin on the back side of the user's thigh is caught in the gap or step formed between the toilet seat and the upper surface of the toilet body be able to.

  In addition, since the armrests of portable toilets are usually arranged substantially parallel to the side edges of the toilet body, toilet seats having side edges arranged substantially parallel to the side edges of the toilet body are used as armrests and armrests. The toilet seat does not interfere with the armrest or the armrest that supports the armrest when the toilet seat is rotated, and as a result, the seat surface of the toilet seat is maximized between the left and right armrests. Can be large.

  If the side edge of the toilet seat is not arranged substantially parallel to the side edge of the toilet body, for example, if it is arranged in a “C” shape, The part with the maximum width will interfere with the armrests and the struts that support the armrests. On the other hand, if the part where the width of the toilet seat is the maximum is designed not to interfere with the armrests and the struts that support the armrests, the maximum distance between the left and right armrests is fixed, so the outer width of the toilet seat is relatively small. As a result, the seat surface of the toilet seat may not be necessary and sufficient.

  Further, when the portable toilet is provided with an armrest and a support column that supports the armrest from below, the toilet seat having the substantially rectangular outer shape as described above has the front end portions (corner portions) on the front side of the toilet seat in front of the armrest support column. It is preferable to arrange in. Here, the “end portion” of the toilet seat means a corner portion in which the side edge extending in the longitudinal direction of the toilet seat substantially changes its direction to the front edge extending in the width direction of the toilet seat, Not only corners but also corners with R may be used.

  If the front ends of the toilet seat are placed in front of the armrest struts, the front end of the toilet body will be approximately the same shape as the front edge of the toilet seat, and a space for attaching the armrest strut will be secured in the toilet body. can do. For this reason, the user seated on the toilet seat can move his / her legs freely, particularly toward the outside.

  The toilet seat used in the portable toilet of the present invention is a first seat surface that appears substantially linearly in a cross section orthogonal to the tangent line of the first side edge, and is inclined downward toward the opening with respect to the horizontal plane. A first seating surface formed such that the inclination angle of the first seating surface increases continuously from the rear part to the front part of the toilet seat and then decreases continuously and becomes substantially horizontal; 2 is a second seating surface that appears substantially linearly in a cross section perpendicular to the tangent of the side edge of the second side, and the tilt angle of the second seating surface that tilts downward toward the opening with respect to the horizontal plane is from the rear of the toilet seat. It is preferable that the second seating surface is formed so as to continuously increase toward the front portion and then decrease continuously thereafter to become substantially horizontal.

  That is, the toilet seat described above has a first seat surface and a second seat surface across the opening, and both the first and second seat surfaces are inclined from the rear portion to the front portion of the toilet seat. As it goes toward it, it becomes tighter continuously towards the opening, then gradually becomes gentler, and becomes substantially horizontal near the front edge of the toilet seat. Here, the “inclination angle” of the seating surface means an angle with respect to a horizontal plane of a line segment that shows a typical gradient of the seating surface that appears substantially linearly in a cross section orthogonal to the tangent of the side edge.

  Therefore, the first and second seating surfaces guide the user's buttocks to drop into the opening of the toilet seat when the user is seated on the toilet seat. As a result, the first and second seating surfaces raise the skin of the user's buttocks relative to the seating surface and open the user's anus, so that the user can easily excrete. It should be noted that the seat surface that appears substantially linearly in the cross section of the toilet seat does not necessarily need to be composed only of a plane in which the cross section of the toilet seat appears in a straight line, as long as the above-described drop effect is obtained by the inclination of the seat surface. For example, a curved surface slightly depressed downward or a curved surface bulging upward may be included.

  In addition, the inclination angle of the first seating surface is maximized in a toilet seat cross section passing through a dimension line that is orthogonal to the tangent line of the first side edge and has the maximum width of the opening, and the inclination of the second seating surface. The angle is preferably maximized in a toilet seat cross section passing through a dimension line orthogonal to the tangent line of the second side edge and having the maximum width of the opening.

  When the inclination angle of the first seat surface and the inclination angle of the second seat surface are maximized at a position where the width of the opening of the toilet seat is maximized, when the user is seated on the toilet seat of the present invention, Since the user's anus is guided by the first and second seating surfaces near the midpoint of the dimension line where the width of the toilet seat opening is maximum, the user's bowel movement is a bucket installed below the toilet seat. It is possible to drop it into a predetermined position. For this reason, the inclination of the first and second seat surfaces described above prevents the user's defecation from scattering or adhering to the periphery of the bucket, and the user's defecation at a predetermined depth. Since it is surely buried in the water stored inside, it is possible to prevent the generation of off-flavors due to the exposure of feces.

  Normally, if the inclination angle of the first seat surface and the inclination angle of the second seat surface are the maximum near the position where the width of the opening of the toilet seat is maximum, the user's anus is placed on the toilet seat. Since it can be guided near the midpoint of the dimension line where the width of the opening is maximum, the inclination angle of the first seat surface and the inclination angle of the second seat surface are, in a strict sense, the level of the toilet seat opening. It does not have to be the maximum at the position where the width is maximum.

  Since the front end of the toilet body of the portable toilet of the present invention has both end areas curved convexly toward the back of the toilet body, and the protrusion (center area) protrudes convexly toward the front of the toilet body. The user can easily sit deeply behind the toilet body and the toilet seat. Also, when the user sits deeply behind the toilet seat, the protruding part at the front end of the toilet body abuts on the inside of both knees of the user and opens the legs of the user, so the user naturally excretes Will be able to take an easy posture. In addition, the posture in which the user has opened both legs allows the user to wipe the defecation from the front without taking a middle waist posture after excretion, and the user is a care recipient etc. Even if it exists, since the attendant etc. can wipe a user's defecation without holding a user, the burden of an attendant etc. can be reduced significantly.

  Since the portable toilet of the present invention has a so-called box structure, the necessary strength is ensured, and protrusions and steps such as ribs or the like that may cause a user to hook a leg or the like from the surface of the toilet body are eliminated. The surface of the main body can be made smooth. In addition, since the toilet body portion employs a so-called two-piece structure divided into a box portion and an upper surface portion, any part can be molded as an integrally molded product made of resin, and at low cost. A sturdy portable toilet can be provided.

  Furthermore, the portable toilet of the present invention is configured such that the front surface of the toilet body is inclined from the opening edge of the opening downward and rearward of the box, so that the user can stand up from the portable toilet and / or the portable toilet. When the user sits down, the user can draw his / her feet down to the front end of the toilet body or the front edge of the toilet seat or just behind it. As a result, when the user stands up and / or sits down, the weight of the user is mainly moved only in the vertical direction, and the user can easily stand up and sit down.

  The portable toilet of the present invention has a receiving part that easily contaminates the upper surface of the toilet body part with the excrement or dust of the user and requires appropriate cleaning and wiping, and a frame part that detachably supports the receiving part. Therefore, the receiving part can be easily cleaned outside the portable toilet.

  In the present invention, when the side edge of the toilet seat is arranged substantially parallel to the side end of the toilet body, interference with the armrests of the toilet body and the columns that support the armrests during rotation of the toilet seat is prevented. In addition, the gap formed between the toilet seat and the upper surface of the toilet body is formed outside the thigh of the seated user, so that the skin on the back side of the user's thigh is sandwiched between the gap, etc. Is also prevented.

  In the present invention, the seat surface of the toilet seat is continuously tightened toward the opening as the inclination of the seat surface moves from the rear part to the front part of the toilet seat, and then gradually becomes gentle, and is approximately in the vicinity of the front edge of the toilet seat. In the horizontal shape, when the user sits on the toilet seat of the present invention, the user's buttocks are guided to drop into the toilet seat opening, and the user's buttocks skin is relative to the seat surface. Therefore, the user's anus is opened, and the user's defecation is facilitated.

  In the present invention, when both front ends of the toilet seat are arranged in front of the armrest strut, the front end portion of the toilet body is made substantially the same shape as the front edge of the toilet seat, and a space for attaching the armrest strut is provided in the toilet. Since it can be secured in the main body, both legs of the user seated on the toilet seat can move freely.

If the distance is substantially the same as a straight line, not only a straight line with a strict meaning but also a little “ Curved lines that are bent in the shape of "" and curved lines that are slightly bent to draw large arcs are also included. For this reason, it is sufficient that most of the side end portions 25 and 26 extend substantially in a straight line. For example, the leg portions of the portable toilet body 2 are accommodated in a part of the side end portions 25 and 26. A bulge or the like may be formed.

  Further, in the present embodiment, the “front part” means an area near the front of the toilet seat 4 and the portable toilet 1 arranged on the user's ventral side when an adult user sits on the toilet seat 4, and The “rear part” means a region in the vicinity of the back of the toilet seat 4 and the portable toilet 1 arranged on the back side of the user when an adult user sits on the toilet seat 4. The “toilet body end portions 250 and 260” of the side end portions 25 and 26 of the portable toilet 1 are the side end portions 25 and 26 extending in the longitudinal direction of the portable toilet 1 and extending in the width direction of the portable toilet 1. In addition, it means a corner portion that substantially changes its direction to the toilet body front end portion 27, and the corner portion may be not only a corner portion but also a corner portion with an R.

  The toilet body first toilet body end 270 of the portable toilet 1 of the present embodiment includes a first inflection point 271 between the first toilet body end 250 and the toilet body protrusion 270, and A curved portion 273 including a second inflection point 272 is provided between the second toilet body end 260 and the toilet body protrusion 270. In the present embodiment, the “inflection point” is a portion where the toilet body front end portion 27 changes from a convex shape toward the rear of the toilet body portion 2 to a convex shape toward the front of the toilet body portion 2. It is sufficient that the changing part is not only a point but also a straight line.

  Thus, the portable toilet 1 of the embodiment is curved and retracted so that both end areas of the toilet body front end 27 are convex toward the back of the toilet body 2 as compared with the toilet body having a rectangular flat surface portion. Therefore, even if the user tries to sit behind the toilet seat 4 of the portable toilet 1, the front end portion 27 of the toilet body 2 is compared with the conventional toilet seat where both end areas of the front edge are not retracted. There is no obstacle to hitting the back of your knee. For this reason, the user can easily sit deeply behind the toilet seat 4 of the portable toilet 1 of the present embodiment.

  Further, in the portable toilet 1 of the present embodiment, the center portion of the toilet body front end portion 27 protrudes forward relative to both end areas of the front end portion 27, so that the user can sit deeply behind the toilet seat 4.

It has a leading edge 45 arranged in parallel.

  That is, if the front part or a part of the front edge 45 of the toilet seat 4 is substantially the same shape as the front end part 27 of the toilet body 2, even if the user tries to sit behind the toilet seat 4 of the portable toilet 1, Compared to a conventional toilet seat in which both end areas of the front edge are not retracted, the front end 27 of the toilet body 2 and the front edge 45 of the toilet seat 4 do not impinge on the back side of the user's knee, and The fit of the legs when seated can be enhanced. Further, if the front part or a part of the front edge 45 of the toilet seat 4 has substantially the same shape as the front end part 27 of the toilet body part 2, the toilet body protrusion part 270 of the toilet body front end part 27 and the front edge 45 of the toilet seat 4 Since the protrusion 450 cooperates widely with the inner side of the user's knees, both the legs of the user can be smoothly opened.

  Further, the posture in which the user opens both legs allows the user to wipe the defecation from the front by himself without taking the middle / lower back posture after excretion. In addition, even if the user is an elderly person or care recipient who must be wiped by an attendant or caregiver, the attendant may wipe the user's defecation without holding the user. As a result, the burden on the attendant and the like can be greatly reduced.

  In the present embodiment, the curved portion 273 of the toilet body front end portion 27 is a first curved curved convexly toward the rear of the toilet body portion 2 between the first toilet body end portion 250 and the first inflection point 271. A curved portion 274, a second curved portion 275 convexly curved toward the rear of the toilet body 2 between the second toilet body end 260 and the second inflection point 272, and the first Between the inflection point 271 and the 2nd inflection point 272, the 3rd curved part 276 curved convexly toward the front of the toilet main body part 2 is included (refer FIG. 4, 5).

  As described above, the curved portion 273 in the both end areas of the toilet body front end 27 is convexly curved toward the rear of the toilet body 2, and the curved portion 273 in the center portion of the toilet body front end 27 is the toilet body. When the user curves deeply toward the front of the part 2, when the user sits deeply behind the toilet seat 4, the shape of both end areas of the toilet body front end 27 fits on the back side of the user's knee. Therefore, the user's both legs are guided to open gently and smoothly. Further, the shape of the toilet main body front end 27 described above is convenient as a mark of a position where the user puts his / her leg when sitting on the toilet seat 4.

  FIG. 8 shows a schematic diagram of the receiving part 3 in a state where the bucket 6 is suspended, which is separated from the upper surface part 28 of the toilet body part 2.

  As will be understood with reference to FIGS. 3, 4, and 8, in the present embodiment, the upper surface portion 28 of the toilet body 2 has a frame portion 24 and a first opening 30 defined by an edge wall 31. And is divided into a receiving portion 3 that is detachably attached to the frame portion 24 inside the frame portion 24.

  The upper surface 28 of the toilet body 2 supports the armrest 20 and the backrest 21 and is connected to the box 23 to improve the strength of the toilet body 2 and to support the toilet seat 4 from below. It also functions to support the bucket 6 so as to be suspended in the first opening 30 via the edge wall 31 defining one opening 30. For this reason, in the upper surface part 28 of the toilet body 2, in particular, the first opening 30 and its peripheral part are easily contaminated by the excrement and dust of the user, and it is necessary to appropriately clean and clean it. .

  For this reason, in the present embodiment, the upper surface portion 28 of the toilet body 2 is divided into a receiving portion 3 composed of the first opening 30 and its peripheral portion, and a frame portion 24 that detachably supports the receiving portion 3. The receiving part 3 is separated from the toilet body part 2 so that it can be easily cleaned outside the portable toilet 1. Therefore, if the receiving part 3 has a structure that can be easily detached from the toilet body part 2, the toilet body part 2 is separated into the frame part 24 (upper surface part 28 excluding the receiving part 3) and the box part 23 as in this embodiment. It is not necessary that the frame portion 24 and the box portion 23 are integrated.

  Moreover, the receiving part 3 provides the bowl-shaped groove part 32 around the 1st opening part 30 of the receiving part 3, and a user's excrement etc. hangs down to other parts of the toilet body part 2, or is scattered. Can be prevented. Further, when the toilet seat 4 and the lid portion 5 are pivotably attached to the receiving portion 3, the toilet seat 4 and the lid portion 5 can be detached from the toilet body portion 2 at once using the receiving portion 3, so that the portable seat portion 4 and the lid portion 5 are portable. The toilet 1 can be more easily cleaned (see FIGS. 3 and 8).

  Next, the feature of the toilet seat 4 attached to the portable toilet 1 of this embodiment is described. FIG. 9 shows a schematic diagram of the toilet seat 4 of the present embodiment, and FIG. 10 shows a plan view of the toilet seat 4 of the present embodiment.

  The toilet seat 4 attached to the portable toilet 1 of this embodiment is rotatably attached to the receiving part 5 of the toilet body 2 as understood by comparing FIG. 1 and FIG. The toilet seat 4 has a first side edge 43 disposed substantially parallel to the first side end 25 of the toilet body 2 when the toilet seat 4 is placed on the upper surface 28 of the toilet body 2. And the 2nd side edge 44 arrange | positioned substantially parallel to the 2nd side edge part of a toilet main-body part is provided.

  In the present embodiment, when the first and second side edges 43 and 44 of the toilet seat are arranged substantially parallel to the first and second side end portions 25 and 26 of the toilet body 2, respectively, the outer shape of the toilet seat 4 Can also be formed in the outer side of the thigh of the user who is seated with a gap or step formed between the toilet seat 4 and the upper surface 28 of the toilet body 2. For this reason, the toilet seat 4 having the first and second side edges 43 and 44 as described above has a gap or step formed between the toilet seat 4 and the upper surface portion 28 of the toilet body 2. Since it is possible to eliminate crossing the back side of the thigh in an oblique direction, the skin on the back side of the user's thigh is formed between the toilet seat 4 and the upper surface 28 of the toilet body 2. And the problem of being caught between steps can be solved.

  Moreover, in the portable toilet 1 of this embodiment, since the armrest 20 is arrange | positioned substantially parallel to the side edge parts 25 and 26 of the toilet body part 2, it is substantially parallel to the side edges 25 and 26 of the toilet body part 2. The toilet seat 4 having the arranged side edges 43 and 44 is arranged adjacent to the armrest 20 and the support column 200 that supports the armrest. However, when the toilet seat 4 rotates, the toilet seat 4 supports the armrest 20 and the armrest. And as a result, the seat surface of the toilet seat 4 can be maximally sized between the left and right armrests 20.

  If the side edges 43, 44 of the toilet seat 4 are not arranged substantially parallel to the side ends 25, 26 of the toilet body 2, for example, in a “C” shape, the seat surface 41, When 42 is made a necessary and sufficient size, the portion where the width of the toilet seat 4 is maximum interferes with the armrest 20 and the support 200 supporting the armrest. On the contrary, when the portion where the width of the toilet seat 4 is maximized is a size that does not interfere with the armrest 20 or the support column 200 that supports the armrest, the allowable maximum distance between the left and right armrests 20 is determined. As a result, the seat surfaces 41 and 42 of the toilet seat 4 cannot be made large and necessary.

  Moreover, the portable toilet 1 of this embodiment is supporting the armrest 20 and the support | pillar 200 which supports this armrest from the downward direction by the upper surface part 28 of the portable toilet 1, and the both ends of the front side of the toilet seat 4 which has a substantially rectangular external shape. The (corner portion) is disposed in front of the armrest support 200. Here, the “end portion” of the toilet seat 4 is a corner portion where the side edges 43 and 44 extending in the longitudinal direction of the toilet seat 4 substantially change the direction to the front edge 45 extending in the width direction of the toilet seat 4. This means that the corner portion may be not only a corner portion but also a corner portion with an R.

  In the present embodiment, since both front end portions 430 and 440 of the toilet seat 4 are arranged in front of the armrest column 200, the shape of the front end portion 27 of the toilet body 2 is substantially the same shape as the front edge 45 of the toilet seat 4. In addition, a space for mounting the armrest support 200 can be secured in the toilet body 2. For this reason, the user seated on the toilet seat 4 can freely move his / her legs particularly toward the outside.

  FIG. 11 is a sectional view of the toilet seat 4 shown in FIG. 10 from the AA section to the DD section orthogonal to the first side edge 43 and the second side edge 44, and the toilet seat. A front view of 4 is shown.

  The toilet seat 4 used in the portable toilet 1 of the present embodiment has a first seat surface 41 and a second seat surface 42 with an opening 40 interposed therebetween (see FIGS. 9 and 10). As shown in FIG. 11, the first seating surface 41 that appears in a substantially straight shape in a cross section orthogonal to the tangent to the first side edge 43 is inclined downward toward the opening 40 with respect to the horizontal plane. The inclination angle α of the first seating surface 41 is continuously increased from the rear part to the front part of the toilet seat 4 and then continuously decreased to become substantially horizontal. In addition, the second seating surface 42 that appears substantially linearly in a cross section perpendicular to the tangent to the second side edge 44 is inclined at an angle of the second seating surface 42 that tilts downward toward the opening 40 with respect to the horizontal plane. α is formed so as to continuously increase from the rear part to the front part of the toilet seat 4 and then continuously decrease to become substantially horizontal.

  That is, the inclinations of the first and second seat surfaces 41 and 42 are both continuously tightened toward the opening 40 from the rear part to the front part of the toilet seat 4, and then gradually become gentle. 4 is substantially horizontal in the vicinity of the front edge 45. Here, the “inclination angle” of the seating surfaces 41, 42 is a horizontal plane of a line segment representing a typical gradient of the seating surfaces 41, 42 appearing substantially linearly in a cross section orthogonal to the tangent line of the side edges 43, 44. It means the angle with respect to (FIG. 11).

  Therefore, the first and second seat surfaces 41 and 42 guide the user's buttocks into the opening 40 of the toilet seat 4 when the user is seated on the toilet seat 4. As a result, the first and second seating surfaces 41 and 42 lift the skin of the user's buttocks relative to the seating surfaces 41 and 42 to open the user's anus. The effect of doing. It should be noted that the seat surfaces 41 and 42 appearing substantially linearly in the cross section of the toilet seat 4 are not necessarily limited to planes in which the cross section of the toilet seat 4 appears as a straight line as long as a drop effect can be obtained by the inclination of the seat surfaces 41 and 42. It is not necessary to be configured, and as shown in FIG. 11 (d), it may include a curved surface slightly depressed downward.

  In the present embodiment, the inclination angle α of the first seating surface 41 passes through a dimension line 401 (FIG. 11) that is orthogonal to the tangent line of the first side edge 43 and has the maximum width of the opening 40. It is the largest in the toilet seat cross section. Further, the inclination angle α of the second seating surface 42 is maximum in the toilet seat cross section passing through the dimension line 401 (FIG. 11) orthogonal to the tangent line of the second side edge 44 and having the maximum width of the opening 40. It has become.

  When the inclination angle α of the first seat surface 41 and the inclination angle α of the second seat surface 42 are maximized at the position where the width of the opening 40 of the toilet seat 4 is maximized, the user can When seated on the toilet seat 4, the user's anus is guided by the first and second seat surfaces 41, 42 near the midpoint of the dimension line 401 where the width of the opening 40 of the toilet seat 4 is maximum, The user's stool can be dropped to a predetermined position in a bucket 6 installed below the toilet seat 4 (see FIG. 1). Therefore, the inclination of the first and second seat surfaces 41 and 42 prevents the user's defecation from scattering or adhering to the periphery of the bucket 6, and the user's defecation at a predetermined depth. Since it is surely buried in the water stored in the bucket 6, it is possible to prevent the generation of a strange odor due to the exposure of feces.

  If the inclination angle α of the first seat surface 41 and the inclination angle α of the second seat surface 42 are maximum in the vicinity of the position where the width of the opening 40 of the toilet seat 4 is maximum, the user's anus Can be guided in the vicinity of the midpoint of the dimension line 401 where the width of the opening 40 of the toilet seat 4 is maximum, so that the inclination angle α of the first seating surface 41 and the inclination angle α of the second seating surface 42 can be guided. In a strict sense, does not have to be maximized at a position where the width of the opening 40 of the toilet seat 4 is maximized.
