TOILET SEAT AND PORTABLE TOILET WITH SAME <br> <br> <br> Patents - stay tuned to the technology TOILET SEAT AND PORTABLE TOILET WITH SAME

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat to be mounted on a portable toilet (movable portable toilet) and a portable toilet equipped with the toilet seat. More particularly, the toilet seat has a substantially rectangular outer shape, The rear end of the opening portion of the user's body is curved so as to be convexly rearward so as to prevent the skin on the back of the user's thighs (femur) from being caught, and the toilet seat with a higher degree of freedom of the user's seating position, Lt; / RTI &gt; portable toilet.

A portable toilet (portable simple toilet) used for a built-in western style toilet or an elderly person or a handicapped person for excretion in a living room is provided with a toilet seat used for sitting on a seat when the user uses the toilet. The toilet seat functions to prevent the femur or buttocks of the user from directly touching the opening rim of the toilet when the user sits on the toilet and serves to support the user's thighs or buttocks. In the toilet seat, there are two types of U shape in which the rim of the opening is open and O shape in which the rim of the opening is closed. In recent years, O The use of a toilet seat having a shape has become mainstream.

However, in recent years, the portable toilet is generally equipped with an armrest or a backrest. Therefore, the flat portion of the chair on which the toilet seat is placed is often made generally rectangular in order to support the armrest or the backrest. Therefore, if the outer shape of the toilet seat is O-shaped in the portable toilet, the O-shaped toilet seat can form a gap or step along the outer edge of the O-shaped toilet seat between the substantially rectangular flat portion, And the corresponding gap or step is arranged to traverse the back of the thigh of the seated user in the oblique direction. Therefore, in the portable toilet with the outer shape of the toilet seat in the O-shape, when the user sits on the toilet seat and then moves the leg, the skin behind the thigh is moved between the toilet seat and the flat portion of the toilet bowl main body There was a problem in that it was caught in a gap or a step and wounds.

Therefore, in recent years, there has been proposed a method of manufacturing a semiconductor device, which is disclosed in Japanese Patent Application Laid-Open No. 2005-000387 (Patent Document 1), Japanese Patent Application Laid-Open No. 2010-240165 (Patent Document 2), Japanese Laid-Open Patent Publication No. 2012-152256 As disclosed, a toilet seat having a substantially quadrangular outer shape of the toilet seat has been developed so as not to traverse the back of the thigh of a user who is seated with a gap or step between the toilet seat and the flat portion of the toilet bowl body . That is, when the outer shape of the toilet seat is substantially rectangular, a gap or a step formed between the toilet seat and the flat portion of the toilet bowl main body can be formed outside the thigh of the seated user.

However, since the substantially rectangular toilet seat as described above has both ends of the front edge of the toilet seat protruded forward as compared with the O-shaped toilet seat, when the user tries to sit on the rear side of the toilet seat, The front end of the toilet seat is relatively in contact with the front edge of the toilet seat, so that the user can not sit deeper.

Normally, in a portable toilet, the front edge of the toilet seat substantially coincides with the front end portion of the toilet bowl main body, and the support pillars of the armrest are attached near both ends of the front end portion of the toilet bowl main body. Therefore, when both ends of the front edge of the toilet seat are retreated rearward of the toilet bowl main body so that the rear of the user's knee is not relatively in contact with the front edge of the toilet bowl from the front side, There is a problem in that a space for attaching the support pillars of the armrest to the flat portion of the portable toilet is lost.

In addition, a movable toilet having an armrest or a backrest is further provided with support pillars for supporting the armrests and the armrests on the outside of the toilet seat. Further, since the toilet seat is rotatably attached to the toilet body, there has been a design restriction that the toilet seat should not be interfered with the support pillars supporting the armrest or the armrest when the toilet seat is rotated.

Japanese Unexamined Patent Application Publication No. 2005-000387 Japanese Patent Application Laid-Open No. 2010-240165 Japanese Unexamined Patent Application Publication No. 2012-152256

Accordingly, in order to prevent the skin of the back of the user's femur from being caught, the present invention is applied to a toilet seat placed on a movable toilet (movable portable toilet) having a substantially rectangular outer shape, And it is an object of the present invention to provide a toilet seat capable of preventing a user from interfering with a supporting column supporting the armrest or armrest and allowing the user to sit back deeply.

Further, the present invention is not limited to securing a space for attaching the support pillars of the armrest to the flat portion of the portable toilet, and also to prevent the front edge of the toilet seat and the front end portion of the toilet bowl body from moving freely And a toilet seat to which the toilet seat is attached.

Further, in the portable toilet with the toilet seat according to the present invention, not only the required strength is ensured but also the protrusion such as ribs or the step is removed from the surface of the toilet bowl main body, The effect is maximized, and as a result, the user aims to provide a portable toilet seat that can stand up from the portable toilet or sit on the portable toilet with little movement.

The inventors of the present invention have made intensive investigations on the shape and arrangement of the toilet seat attached to a portable toilet with an armrest or a backrest. As a result, the basic shape of the toilet seat has a substantially rectangular shape, It is possible to prevent the skin on the back of the user's thighs from being caught and to allow the user to sit deeper behind the toilet seat by bending back both sides convexly toward the rear of the opening of the toilet seat, And has reached the completion of the invention.

More specifically, according to the present invention, there is provided a toilet seat which is placed on a movable toilet and is used as a toilet seat. The toilet seat has an opening portion closed around the periphery of the toilet seat and a rear end portion of the toilet seat extending outwardly from the first end, A first side edge extending in a straight line shape and a second side edge extending from a second end located on the opposite side of the first side edge and outside the toilet seat to a rear side of the toilet seat, And extends from the first end to the second end via a protrusion located forward of the tip of the opening and has a first inflection point between the first end and the protrusion, And a front edge including a curved portion having a second inflection point therebetween.

According to the present invention, there is provided a toilet seat disposed and used on a portable toilet, comprising: an egg-shaped opening portion with its periphery closed; and an opening portion extending from the first end positioned rearwardly of the opening end portion to the rear portion of the toilet seat, Wherein the width of the toilet seat cross section at a cross section orthogonal to the tangent of the first side frame is continuously reduced from the rear portion of the toilet seat toward the front portion and is then continuously enlarged A second side edge extending from the second end located on the opposite side of the first side edge and outside the toilet seat to the rear side of the toilet seat, the second side edge being located rearward of the tip end of the opening, The width of the cross section of the toilet seat at a cross section orthogonal to the tangent line is continuously increased from the rear portion to the front portion of the toilet seat, And then extending from the first end to the second end via a projection located forwardly of the tip of the opening and a second side edge arranged to be subsequently enlarged and extending between the first end and the projection Is provided with a front edge having a first inflection point and a curved portion having a second inflection point between the second end and the protrusion.

Herein, the portable toilet refers to a movable portable toilet as described in Patent Documents 1 to 3, which is used for the elderly and physically handicapped to be excreted in a living room or the like. The concept of a portable toilet is not limited to a portable toilet manufactured mainly from a resin material, for example, a so-called furniture, which is manufactured from materials such as wood, such as an outer frame, a leg, an armrest, A harmonized portable toilet is also included.

In the present invention means a region near the front of the toilet seat and the movable toilet located on the side of the user when the adult user is seated on the toilet seat, and &quot; rear portion &quot; A toilet seat disposed on the back of the user and an area in the vicinity of the rear of the portable toilet when the user seated on the toilet seat. The term &quot; end portion &quot; of the side edge of the toilet seat means a corner portion whose side edge extending in the longitudinal direction of the toilet seat substantially changes direction to the front edge extending in the width direction of the toilet seat, May be not only angled portions, but also rounded corner portions.

The toilet seat of the present invention is suitable for use on a removable toilet, not a conventional built-in western style toilet.

This is because when both ends of the front edge of the substantially rectangular toilet seat are retreated rearward of the toilet body portion in the portable toilet, both ends of the front end portion of the toilet body portion are also retreated rearward of the toilet body portion, It is an object of the present invention to solve the problem that there is no space for attaching the support pillars of the armrest at the flat portion of the portable toilet. It is another object of the present invention to provide a portable toilet with a supporting column for supporting the armrest and the armrest on the outside of the toilet seat so that the toilet seat interferes with the supporting pillars supporting the armrest or the armrest when the toilet seat is rotated This is because it is one of the important tasks to be solved.

The toilet seat of the present invention is a so-called O type toilet seat having a closed-up opening. The toilet seat of the present invention has first and second side edges extended from an end of the toilet seat located rearward from the end of the opening to a rear portion of the toilet seat in a substantially straight line, . In the present invention, the term " rim " means the contour of the toilet seat shown in the plan view and the section forming the contour. The term &quot; approximately linear shape &quot; means a line segment connecting the two separated points at substantially the shortest distance, and if the distance is substantially the same as a straight line, not only a straight line in a strict sense but also a broken line bent in a somewhat " It also includes a somewhat curved line as you draw the arc.

As described above, the toilet seat of the present invention has a substantially square shape extending from the outer side of the toilet seat to a rear portion of the toilet seat from the front end portion of the opening portion in a substantially straight line shape and having substantially parallel first and second side edges And the inside of the toilet seat has an inner rim that defines openings such as O-shaped or egg-shaped. Therefore, the width of the cross section of the toilet seat at a cross section orthogonal to the tangent of the first side edge, and the width of the cross section of the toilet seat at a cross section orthogonal to the tangent of the second side edge, As shown in Fig. 3, and is continuously enlarged thereafter.

Since the outer shape of the toilet seat of the present invention is substantially quadrangular as described above, it is possible to make the seat surface of the toilet seat a necessary and sufficient size, and the support pillars supporting the armrests and the armrests can be disposed in the first and second The toilet seat does not interfere with the support pillars that support the armrests or the armrests when the toilet seat is rotated, even when the toilet seat is disposed adjacent to the outside of the second side frame.

If the first side edge and the second side edge of the toilet seat are arranged in, for example, &quot; H &quot; shape so that the seat surface of the toilet seat is sufficiently large, It interferes with support pillars that support armrests or armrests. On the contrary, when the width of the toilet seat is maximized, the maximum distance between the left and right armrests is determined so as not to interfere with the support post supporting the armrest or armrest, so that the outer width of the toilet seat becomes relatively small, As a result, the seat surface of the toilet seat can not be made a necessary and sufficient size.

In addition, in the present invention, since the outer shape of the toilet seat is substantially rectangular, a gap or a step formed between the toilet seat and the flat portion of the toilet bowl main body can be formed outside the thigh of the seated user. Therefore, according to the present invention, it is possible to prevent a gap or step between the toilet seat and the flat portion of the toilet bowl main body from crossing in the oblique direction behind the back of the femur of a seated user, It is possible to solve the problem of sticking to a gap or a step formed between the toilet seat and the flat portion of the toilet bowl main body.

The toilet seat of the present invention has a projection located forward of the distal end of the opening, as opposed to the end of the side edge. The toilet seat of the present invention has a front edge extending from the first end to the second end via the corresponding projection and the front edge has a first inflection point between the first end and the projection, And a curved portion having a second inflection point between the second end portion and the projection portion. In the present invention, the &quot; inflection point &quot; is sufficient if the front edge changes from the convex state toward the rear of the toilet seat to the convex state toward the front of the toilet seat, and the changed portion is not only a point, And the like.

As described above, the toilet seat of the present invention is curved and retreated so that both end regions of the front edge are convex toward the rear of the toilet seat as compared with the rectangular toilet seat. Therefore, even if the user tries to sit on the rear side of the toilet seat, The front edge of the toilet seat does not come into contact with the back of the user's knee and is not obstructed as compared with the toilet seat in which the front and rear edge sections of the toilet seat are not retreated. Therefore, the user can easily sit on the rear of the toilet seat of the present invention.

In the toilet seat of the present invention, since the center portion of the front frame protrudes forward relative to the opposite end portions of the front frame, when the user sits deeply in the rear of the toilet seat, the protrusion of the front frame, Thereby bringing the user's two legs apart. Therefore, the user can naturally take an easy posture. In particular, in the case of a male user, since the user can easily direct the lower part of the penis, it is possible to prevent the urination of the user from scattering over the protrusion of the front rim .

In addition, the posture in which the user has opened his or her legs allows the user to wipe the bowel movement from the front side with the magnetic force without taking the posture after the excretion. In addition, even when the user is an elderly person or a caregiver who is required to wipe it out to a person or a caregiver, it is possible to wipe out the user's bowel movement without hugging the user. It is possible to greatly reduce.

In addition, in the present invention, the curved portion of the front rim has a first curve portion curved convexly toward the rear of the toilet seat between the first end portion and the first inflection point, and a second curve portion curved in the backward direction of the toilet seat between the second end portion and the second inflection point And a third curved portion curved convexly toward the front of the toilet seat between the first inflection point and the second inflection point, and a second curved portion convexly curved toward the front of the toilet seat.

As described above, if the curved portions of the both end regions of the front rim are curved convexly toward the rear of the toilet seat and the curved portions of the central portion of the front rim are curved convexly toward the front of the toilet seat, The shape of the both end zones of the front rim is matched to the back of the user's knee so that the two legs of the user are guided to spread elegantly and smoothly. In addition, the shape of the front rim described above is convenient as a target of a position where the user puts his / her leg when the user sits on the toilet seat.

Particularly, when the top edge raised upward from the vicinity of the protruding portion of the front edge is provided on the seat surface formed along the front edge of the toilet seat, the top edge of the front edge and the top edge of the sheet surface near the protruding portion, It is possible to make the two legs of the user smoother and firmly open the legs because the effect is enhanced. Therefore, compared with the case where only the protruding portions are formed on the front edge, the user can take a more comfortable posture So that the urination of the user is prevented from scattering beyond the protrusion of the front rim more reliably.

In the seat surface of the toilet seat of the present invention, a recessed first concave portion is arranged downward from the vicinity of the first curved portion of the front edge, and a recessed second concave portion is formed downward from the vicinity of the second curved portion of the front edge . In other words, the recessed first and second recessed portions facing downward on both sides of the top edge of the seat surface formed along the front edge of the toilet seat are folded by the top edge of the seat surface provided in the vicinity of the protruding portion and the protruding portion of the front edge, The fit feeling of the two legs of the guided user is further improved and at the same time the excessive leg spreading of the two legs of the user is prevented so that the user can take an attitude closer to the ideal type which is easier to perform urination and defecation .

In addition, when the portable toilet seat to which the toilet seat is attached is equipped with the armrest and the supporting column for supporting the armrest from below, it is preferable that the first end and the second end of the toilet seat are arranged forward of the supporting column of the armrest.

When the first end portion and the second end portion of the toilet seat are disposed forward of the support pillars of the armrests, space for attaching the support pillars of the armrests is ensured in the toilet body portion, It can be made substantially the same shape as the rim. Therefore, the user seated on the toilet seat can freely move his or her legs, especially toward the outside.

The toilet seat of the present invention is a first seat surface which is substantially linearly shaped in a cross section orthogonal to a tangent of a first side edge and has an inclination angle of a first seat surface inclined downward toward the opening with respect to the horizontal surface, The first sheet surface being formed so as to continuously increase from the rear portion toward the front portion and to be subsequently decreased to be substantially horizontal, and a second sheet surface which is formed in a substantially straight line shape in a cross section orthogonal to the tangent line of the second side edge. The seat surface is formed so that the inclination angle of the second seat surface inclined downward toward the opening with respect to the horizontal surface continuously increases from the rear portion of the toilet seat toward the front portion thereof, And a second sheet surface.

That is, the toilet seat of the present invention has a first seat surface and a second seat surface with an opening therebetween, and the inclination of the first and second seat surfaces are all inclined toward the front portion from the rear portion of the toilet seat, And subsequently becomes gradually gentle, and becomes approximately horizontal near the front edge of the toilet seat. On the other hand, the term &quot; tilt angle &quot; of the sheet surface herein means an angle with respect to a horizontal plane of a line segment showing a typical gradient of the sheet surface, which is substantially linear in cross section perpendicular to the tangent to the side edge.

Therefore, when the user sits on the toilet seat, the first and second seat surfaces guide the user's buttocks into the opening of the toilet seat. As a result, the first and second seat surfaces raise the skin of the user's buttocks relative to the seat surface, thereby opening the anus of the user, thereby exerting an effect of facilitating the user's excretion. On the other hand, it is not always necessary that the seat surface, which is shown in a substantially linear shape in cross section of the toilet seat, is a flat surface in which the end surface of the toilet seat is straight, and if the slip of the seat surface provides the above- , A somewhat downwardly curved surface, or an upwardly curved surface.

The inclination angle of the first sheet surface is maximized at the cross section of the toilet seat passing through the dimension line perpendicular to the tangent line of the first side edge and the width of the opening maximized, It is preferable to maximize the cross section of the toilet seat passing through the dimension line which is perpendicular to the tangent line of the second side frame and the width of the opening becomes the maximum.

When the inclination angle of the first seat surface and the inclination angle of the second seat surface are maximized at the position where the width of the opening of the toilet seat is maximum, when the user sits on the toilet seat of the present invention, The first and second seat surfaces are guided by the midpoint of the dimension line at which the width of the opening of the toilet seat is maximized, so that the user's bowel movement can fall down to a predetermined position of the urinal installed below the toilet seat. Therefore, the above-mentioned inclination of the first and second sheet surfaces prevents the user's bowel movement from scattering or adhering to the circumference of the barrel and prevents the bowel movement of the user from falling into the water stored in the barrel at a predetermined depth It is possible to prevent the occurrence of bad odors due to exposure of the sides.

On the other hand, normally, if the inclination angle of the first sheet surface and the inclination angle of the second sheet surface are maximum in the vicinity of the position where the width of the opening of the toilet seat is maximum, The inclination angle of the first sheet surface and the inclination angle of the second sheet surface are set so as not to become maximum at the position where the width of the opening of the toilet seat becomes maximum in a strict sense It is not.

Next, according to the present invention, there is provided a portable toilet according to the present invention, to which the toilet seat of the present invention described above is attached. In this case, the portable toilet of the present invention can enjoy all the benefits brought about by the toilet seat of the present invention described above.

In addition, the portable toilet of the present invention is provided with a toilet bowl body portion, and the toilet bowl body portion includes a box portion having an upper opened portion, a box portion having a front portion inclined rearward from the opening edge of the opening toward the lower side of the box portion, And a frame portion connected to an opening rim of the box portion.

As means for improving the strength of the toilet bowl body against deformation, there are a method of providing a bending rib or a reinforcing rib on the opening rim or side surface of the toilet bowl body, or a method of disposing a panel on each surface of the toilet bowl body, A method of making a box structure, and the like are known.

In particular, since the bending rib of the opening rim is a protrusion protruding outward from the body of the toilet in terms of structure, when the bending rib is provided in the body of the toilet, when the user moves the leg in the portable toilet or in the vicinity of the movable toilet, As shown in FIG. Therefore, in the present invention, by employing a box structure which is advantageous for eliminating the protrusion such as the bending ribs, it is possible to prevent a protrusion or a step, which is likely to be caught by the user from the front part of the toilet bowl, So that the front portion of the toilet bowl main body is formed in a smooth shape.

In the present invention, the so-called two-piece structure is employed, and the toilet bowl main body portion is made up of a box portion having an opened upper portion and a corresponding And a frame portion connected to an opening rim of the opening by a screw or the like, thereby solving the above problem. Therefore, in the present invention, both the box portion and the frame portion can be molded as a one-piece molded article made of resin, and as a result, a portable toilet can be provided which is robust at low cost.

In the portable toilet of the present invention, since the front portion of the box portion is inclined rearward from the opening rim of the opening toward the bottom of the box portion, the user pulls his / her foot to the bottom or rear of the front edge of the toilet seat . Therefore, in the portable toilet of the present invention, when the user stands up from the portable toilet and / or when the user sits on the portable toilet, the weight shift mainly occurs only in the vertical direction. Therefore, Seating on the toilet becomes easy.

In addition, since a gap or the like formed between the toilet seat and the flat portion of the toilet bowl main body is formed outside the femur of the seated user, it is also prevented that the skin behind the user's thigh is caught in the gap or the like.

Since the front edge of the toilet seat of the present invention is curved convexly toward the rear of the toilet seat so that both ends of the toilet seat are convexly protruded toward the front of the toilet seat, So that the user can sit down deeply. Further, when the user sits deeply in the rear of the toilet seat, the projection of the front edge contacts the inside of both knees of the user to open the two legs of the user, so that the user can naturally take an easy posture. In addition, the posture in which the user makes two legs allows the user to wipe his / her bowel movement from the front with his / her own hand without exerting an uncomfortable posture after excretion, and even when the user is a person who requires a caregiver, The user can wipe away the user's bowel movement without hugging the user, so that the burden on the person who is on the way can be greatly reduced.

The seat surface of the toilet seat of the present invention is characterized in that the inclination of the seat surface continuously increases toward the opening portion from the rear portion toward the front portion of the toilet seat and then gradually becomes gentle, As shown in Fig. Therefore, when the user sits on the toilet seat of the present invention, the buttocks of the user are guided to fit into the opening of the toilet seat, so that the skin of the user's buttocks can be raised relative to the seat surface, The anus is opened, and the bowel movement of the user becomes easy.

When the toilet seat of the present invention is disposed so that the end of the front edge of the toilet seat is positioned forward of the support post of the armrest, space for attaching the support pillars of the armrest can be ensured, The user who is seated on the toilet seat can freely move his / her two legs, especially toward the outside.

The portable toilet according to the present invention has the toilet seat of the present invention described above and further has the so-called box structure, so that the required strength can be ensured and the user can freely lift the leg from the surface of the toilet bowl main body It is possible to eliminate protrusions or steps such as ribs which are likely to make the surface of the toilet bowl main body smooth. In addition, since the toilet bowl main body adopts a so-called two-piece structure that is divided into a box portion and a frame portion, it is possible to mold all the components as an integral molded article made of resin, and to provide a portable toilet seat which is robust at low cost. It is needless to say that the portable toilet of the present invention can enjoy all the benefits brought about by the toilet seat of the present invention described above.

In addition, the portable toilet of the present invention allows the front portion of the toilet body portion to be inclined rearward from the opening rim of the opening to the bottom of the box portion, so that when the user stands up from the portable toilet and / or seats on the portable toilet, It becomes possible to pull the foot of the user to the bottom of the front edge of the toilet seat. As a result, the weight shift of the user during the first occurrence and / or the sitting of the user becomes mainly the up and down movement, so that the standing and sitting can be facilitated.

As described above, since the toilet seat 4 of the present embodiment has a substantially rectangular outer shape and the opening portion 40 is of an egg shape, the seat surfaces 41 and 42 of the toilet seat 4 can be made sufficiently large Even if the support pillars 200 for supporting the armrests 20 and the armrests of the portable toilet 1 are disposed adjacent to the outside of the first and second side edges 43 and 44 of the toilet seat 4 The toilet seat 4 does not interfere with the armrest 20 or the support pillars 200 that support the armrests when the toilet seat 4 is rotated (see FIGS. 1 and 2).

If the first side edge 43 and the second side edge 44 of the toilet seat 4 are arranged in the shape of a "cube", for example, and the seat surfaces 41, 42 of the toilet seat 4, The portion where the width of the toilet seat 4 becomes maximum interferes with the support pillars 200 that support the armrests 20 and the armrests. On the other hand, if the maximum width of the toilet seat 4 is set so as not to interfere with the armrest 20 or the supporting column 200 supporting the armrest, the maximum distance between the left and right armrests 20 is determined The outer width of the toilet seat 4 becomes relatively small. As a result, the seat surfaces 41, 42 of the toilet seat 4 can not be secured in a required and sufficient size.

In addition, in the toilet seat 4 of the present embodiment, a gap or a step formed between the side edges 43, 44 of the toilet seat 4 and the flat portion of the toilet bowl main body 2, And is formed outside the thigh (see Fig. 1). Therefore, in the present embodiment, it is possible to prevent a gap or step between the toilet seat 4 and the flat portion of the toilet bowl main body 2 from traversing the back of the thigh of the seated user in the oblique direction, It is possible to solve the problem that the skin behind the thigh of the user is caught by a gap or a step formed between the toilet seat 4 and the flat portion of the toilet bowl main body 2. [

5, the first side edge 43 of the toilet seat 4 has a first end 430 located on the outer side of the toilet seat 4 behind the front end 400 of the opening 40 And the second side edge 44 has a second end portion 440 located on the outer side of the toilet seat 4 behind the front end portion 400 of the opening portion 40.

The front edge 45 also has a first end portion 430 and a second end portion 440 which are common to the first side edge 43 and the second side edge 44, And a protrusion 450 located forward of the protrusion 440. In addition, the front edge 45 has a first inflection point 451 between the first end 430 and the protrusion 450 and a second inflection point 452 between the second end 440 and the protrusion 450.
