Here, in the present invention, portable toilet refers to being drained for the elderly and disabled person in room etc., special
Portable simplified toilet seat described in sharp document 1~3.In addition, in the concept of portable toilet, in addition to mainly by resin material
Other than the portable toilet of manufacture, further include such as other than the toilet seat of portable toilet outline border, leg, handrail, backrest
By the portable toilet of the manufacture of the materials such as timber, so-called style of furniture.
In the present invention, " front " refers to when adult user is seated at toilet seat, configures the abdomen in user
The region of the front adjacent of the toilet seat and portable toilet of side, furthermore " rear portion ", which refers to, is seated at closestool in adult user
When seat ring, the region near the toilet seat of back side of user and the rear of portable toilet is configured.In addition, toilet seat
" end " of the lateral margin of circle refers to that the lateral margin of the length direction extension along toilet seat is prolonged towards the width direction along toilet seat
The corner part that the leading edge stretched substantially is changed direction, the corner part can be not only corner, be also possible to fillet
Corner.
Toilet seat of the invention is applicable not only to common fixed Western-style toilet seat, is particularly suitable for being positioned in just
It takes and is used in formula lavatory.
This is because it is an object of the present invention to solve following projects: in portable toilet, in general square shape
In the case that the up-front both ends of toilet seat are retreated to the rear of lavatory main part, the two of the front end of lavatory main part
End is also retreated to the rear of lavatory main part therewith, therefore there is no the pillars of installation handrail in the planar portions of portable toilet
Space.In addition, also as the invention solves an important project be, the outside of toilet seat configured with handrail and
Support handrail pillar portable toilet in, by toilet seat be set as toilet seat rotate when the toilet seat will not with help
The shape that hand, the pillar for supporting handrail interfere.
Toilet seat of the invention is have the opening portion of periphery seal, so-called O-shaped toilet seat.In addition, this
The toilet seat of invention has in the outside of toilet seat from the end for being located at the front end position rearward than opening portion
Substantially linearly extend to first and second lateral margin at the rear portion of toilet seat, and the whole shape with general square shape.It needs
It is noted that in the present invention, " edge " refers to the profile of the toilet seat shown in a top view and forms the end of the profile
Face.In addition, " substantially linear " refer to by isolated two o'clock with it is roughly the shortest distance connection line segment, as long as apart from it is upper with it is big
It causes identical, then includes not only proper straight line, further include slight curvature at the broken line of " (Japanese) く shape " or to describe
The curve of the mode slight curvature of big circular arc.
In this way, toilet seat of the invention has the shape of general square shape in the outside of toilet seat, have from opening
The front end in portion is in first and second side for substantially linearly extending to the rear portion of toilet seat and substantially parallel arranging
Edge, and there is the inner edge for the opening portion for dividing O-shaped or egg shape etc. in the inside of toilet seat.Therefore, with the first lateral margin
The width and the toilet seat in the section orthogonal with the tangent line of the second lateral margin of toilet seat section in the orthogonal section of tangent line
The width of section with continuously reducing from the rear portion of toilet seat towards front, continuously expands later.
It, can be by toilet seat since the shape of toilet seat of the invention is set as general square shape as described above

Handrail, the pillar for supporting handrail, in toilet seat rotation, toilet seat will not occur with the pillar of handrail, bearing handrail
Interference.
If by the first lateral margin of toilet seat and the second lateral margin be configured to such as " (for example) Ha shape " and by toilet seat
The seat surface of circle is set as necessary and enough sizes, then the width the best part of toilet seat can be with handrail, bearing handrail
Pillar interferes.On the contrary, will not be sent out with the pillar of handrail, bearing handrail if being formed as the width the best part of toilet seat
The maximum distance of the size of raw interference, the then permission between the handrail of left and right determines, therefore the shape width of toilet seat becomes smaller relatively,
As a result, the seat surface of toilet seat can not be made to keep necessary and enough sizes.
In turn, in the present invention, since the shape of toilet seat is general square shape, toilet seat and lavatory are formed in
Gap, step difference between the planar section of main part are formed in the outside of the huckle of the user after taking a seat.Therefore, at this
In invention, incline due to can be avoided the gap being formed between toilet seat and the planar section of lavatory main part, step difference edge
The inside of the huckle of user of the tilted direction after taking a seat, therefore the skin of the inside of the huckle of user can be eliminated
The problem of being sandwiched into the gap formed between toilet seat and the planar portions of lavatory main part, step difference.
Toilet seat of the invention has the front end position on the front conversely being positioned at the end of lateral margin than opening portion
The protruding portion set.Also, before toilet seat of the invention is with the second end is extended to via the protruding portion from first end
Edge, and then the leading edge is included between first end and protruding portion with the first inflection point and from the second end between protruding portion
Curve part with Second Inflexion Point.It should be noted that in the present invention, " inflection point " as long as from leading edge towards toilet seat
It not only include the variation to the part for the state change protruded towards the front of toilet seat in the state of the protrusion of rear
Part be point the case where, include the case where being made of straight line.
In this way, compared with the toilet seat of rectangle, toilet seat of the invention makes up-front two end regions with towards closestool
The mode of the rear protrusion of seat ring is bent and retreats, therefore, even if user sits down to the rear of toilet seat, before previous
The toilet seat that two end regions of edge stand fast is compared, the leading edge of toilet seat will not with the interior side contacts of the knee of user and
As obstacle.Therefore, user easily can sit deeper to the rear of toilet seat of the invention.
In addition, in the toilet seat of present embodiment, since up-front center portion is more opposite than up-front two end regions
Ground protrudes forwards, therefore when user sits deeper to the rear of toilet seat, and the two of up-front protruding portion and user
The inside of knee abuts, and two legs of user is guided to diverge.Therefore, user can naturally take the appearance for being easy excretion
In the case where gesture, especially male user, it can easily make sexual organ downward, therefore can be avoided the row of user
Urine crosses up-front protruding portion and splashes.
In addition, after excretion, user is not necessarily to take the posture slightly bent over for the posture of two leg of user fork,
Can defecation voluntarily be wiped from front.In addition, even if user has to be by nurse or nursing staff is wiped
The elderly or in the case where needing nursing staff, nurse is equal can be wiped the defecation of user without taking user in one's arms,
Therefore the burden of nurse etc. can be greatly decreased.
In turn, in the present invention, it is preferred that up-front curve part includes: the court between first end and the first inflection point
The first bending section of convex is bent to the rear of toilet seat；Towards toilet seat between the second end and Second Inflexion Point
Rear bends to the second bending section of convex；And it is bent between the first inflection point and Second Inflexion Point towards the front of toilet seat
At the third bending section of convex.
As described above, if the rear of curve part towards the toilet seat of up-front two end regions bends to convex, and leading edge
Center portion curve part towards convex is bent in front of toilet seat, then sat in user to the rear of toilet seat
When deeper, the fit inside of the knee of the shape and user of up-front two end regions, therefore gentle and swimmingly guidance use
Two legs of person are diverged.In turn, above-mentioned up-front shape becomes the position that oneself leg is placed when user sits down to toilet seat
Label, therefore it is easy to use.
Especially have on the seat surface of toilet seat formed along leading edge and is roused upward near up-front protruding portion
When the top risen, the top of the seat surface near up-front protruding portion and protruding portion acts synergistically and improves the two legs fork of user
Effect is guided, therefore more two legs of user can be made smoothly and reliably to diverge.Therefore, protruding portion is simply formed with in leading edge
The case where compare, user can it is more natural and so take be easy excretion posture, can be more reliably prevented from user's
Urination crosses up-front protruding portion and splashes.
In addition, being formed about downward on the seat surface of toilet seat of the invention in up-front first bending section
First recess portion of recess, also, the second recess portion being recessed downward is formed about in up-front second bending section.That is,
First and second recess portion that the two sides at the top of the seat surface formed along the leading edge of toilet seat are recessed downward passes through leading edge
Protruding portion and the seat surface being arranged near protruding portion top and further increasing be guided two legs fork user two
The cooperation sense of leg, and prevent the excessive fork of two legs of user, thus can make user take close to be easier urination,
The posture of the ideal form of defecation.
In addition, the portable toilet for being equipped with toilet seat have handrail and support from below the handrail pillar feelings
Under condition, preferably the first end of toilet seat and the second end are configured to more closer to the front than the pillar of handrail.
It, can be in lavatory when the first end and the second end of toilet seat are configured to more closer to the front than the pillar of handrail
On the basis of the space for ensuring to install the pillar of handrail in main part, also the shape of toilet main body front end is set as and toilet seat
The leading edge same shape of circle.Therefore, the user being seated on toilet seat can make two legs of oneself freely, especially
It is directed towards outside and moves freely through.
Preferably, toilet seat of the invention has: the first seat surface, in the section orthogonal with the tangent line of the first lateral margin
In be in substantially linear, be with respect to the horizontal plane formed as towards the tilt angle of opening portion the first seat surface inclined downward, with
Continuously increase from the rear portion of toilet seat towards front, continuously reduce later and become it is approximate horizontal；And second
Face is in substantially linear in the section orthogonal with the tangent line of the second lateral margin, with respect to the horizontal plane downwards towards opening portion
The tilt angle of inclined second seat surface is formed as, with continuously increasing from the rear portion of toilet seat towards front, Zhi Houlian
It reduces and becomes approximate horizontal continuously.
That is, toilet seat of the invention has the first seat surface and the second seat surface for clipping opening portion, also, first and second
Seat surface inclination with from the rear portion of toilet seat towards front and towards opening portion, continuously steepening is high and steep, continuously become later
Gently, and near the leading edge of toilet seat become approximate horizontal.It should be noted that here, " tilt angle " of seat surface
Refer in the section orthogonal with the tangent line of lateral margin in substantially linear, indicate seat surface representative angle line segment relative to

Therefore, when user is seated at toilet seat, first and second seat surface is so that the buttocks of the user falls into horse
Mode in the opening portion of bucket seat circle guides.As a result, first and second seat surface is by the skin phase of the buttocks of user
Seat surface is relatively lifted, the anus of user is opened, therefore can play becomes easy the excretion of user in this way
Effect.As long as it should be noted that being capable of inclining by seat surface in the seat surface of substantially linear in the section of toilet seat
It tiltedly obtains and falls into effect, it also may include being slightly toward that the section of toilet seat, which need not be only made of linear plane,
The curved surface of lower section recess or the curved surface expanded upward.
Moreover it is preferred that the tilt angle of the first seat surface is orthogonal and opening with the tangent line of the first lateral margin
It is in the toilet seat section of the maximum dimension line of width maximum, also, the tilt angle of the second seat surface is cut with the second lateral margin
Line is orthogonal and the toilet seat section of the maximum dimension line of width of opening in it is maximum.
If the width of the tilt angle of the first seat surface and the tilt angle of the second seat surface in the opening portion of toilet seat is maximum
Position become maximum, then when user is seated at toilet seat of the invention, the anus of user passes through first and second
Seat surface is directed near the midpoint of the maximum dimension line of width of the opening portion of toilet seat, therefore, the defecation energy of user
Enough fall to the specified position being set in the tub of the lower section of toilet seat.Therefore, the inclination energy of first and second seat surface
It enough prevents the defecation of user to splashing around tub or attachment, and is buried in the defecation of user reliably to provide
Depth lodge in the water in tub, therefore foreign odor caused by the exposing of defecation can be prevented.
It should be noted that in general, if the tilt angle of the first seat surface and the tilt angle of the second seat surface are in toilet seat
Opening portion the maximum position of width near become maximum, then the anus of user can be guided opening to toilet seat
Near the midpoint of the maximum dimension line of the width of oral area, therefore the tilt angle of the first seat surface and the tilt angle of the second seat surface are simultaneously
The maximum position of the nonessential width in a strict sense in the opening portion of toilet seat becomes maximum.
