Description

  The present invention relates to a toilet for pet animals used when pet animals such as cats are raised indoors.

As an example of a pet animal toilet, Patent Document 1 shown below proposes the following cat toilet.
A toilet for pets, comprising an outer container main body having an upper opening, and an interior of the outer container main body, forming a mesh-like body at a bottom center portion, and sand on the mesh-like body An inner container body provided in the upper end opening of the inner container body, and an excretion hole having an elliptical shape with the major axis in the longitudinal direction of the container so that the pet can rest on the entire periphery A lid portion having only a central portion, and the shortest length between the peripheral edge in the major axis direction of the hole portion of the lid portion and the peripheral edge of the lid portion, and the short axis of the hole portion of the lid portion The shortest length between the peripheral edge in the direction and the peripheral edge of the lid is 5 to 8 cm, and the ratio of the major axis dimension of the hole to the inner dimension of the lid in the container longitudinal direction is 56 to 60. % And the short axis dimension of the hole part relative to the inner dimension of the lid part in the container short direction. Ratio, toilet pets, which is a 40 to 47% (see claim 1 of Patent Document 1).

Then, as an operation when the cat is added, the following is stated in the opinion dated March 20, 2006 in the examination process of the invention shown in the above patent document.
“In the pet toilet according to the first invention of the present application, after the cat puts his face inside the inner container body from the hole of the lid (I) and confirms the smell of sand, (II) the hole of the lid As a result of moving forward on the lid part so as to position the waist on the formed depression, (III) (IV) Both front legs are naturally placed on the front edge of the cat on the lid, and both hind legs are placed on the left and right edges of the cat on the lid, and then excreted. V) After reversing the front and back direction on the lid, (VI) After putting the face into the inside of the inner container body from the hole of the lid and confirming the smell of the excreted part (dent part) on the sand by sniffing (VII) After putting one forefoot into the inside of the inner container body from the hole in the lid and hiding sand so as to hide the excretion part (dent part), (VIII) Retreat I will leave.
That is, in the pet toilet according to the first invention of the present application, the lid portion has a central hole portion for excretion having an elliptical shape with the major axis oriented in the longitudinal direction in the longitudinal direction of the container so that the cat can rest on the entire periphery. Only the shortest length of the peripheral edge of the lid part in the major axis direction and the peripheral edge of the lid part, and the peripheral edge of the lid part in the minor axis direction of the lid part and the lid part. And the ratio of the long axis dimension of the hole to the inner dimension of the lid in the container longitudinal direction is 56 to 60%, and the container short Since the ratio of the short axis dimension of the hole portion to the inner dimension of the lid portion in the hand direction is 40 to 47%, the above behavior (both the sand at the location where the odor of sand is to be excreted is removed) After digging with the forefoot, it moves forward and excretes) While putting the forefoot in the part and making it possible to dig and sand with a natural posture without difficulty, the cat rides on the lid in the direction of the longitudinal direction of the container and puts the foot on the periphery Since it can be naturally positioned on the hole so that it does not get dirty with excrement when excreting, it can be used safely without any rough phase. It is what you did. "
Japanese Patent No. 3824887

  As stated in the above opinion, "Put your forefoot naturally on the front edge of the cat on the lid, and place your hind legs on the left and right edge of the cat on the left and right side." This is ideal, but in practice this is not always the case.

In the thing of the patent document 1, since the defecation in the posture which a human is ideal is made to force a cat, for example, since the case where a cat defecates sideways is not assumed, defecation is a lid part in that case. It is also possible to fall on the lid without passing through the excretion hole.
Also, if you try to be a cat, if you are forced into a cramped posture, you may stop using the toilet in the first place.

Further, as shown in FIG. 1 of Patent Document 1, the pet toilet proposed in Patent Document 1 has an inner container body having an inverted trapezoidal section in the same shape inside an outer container body having an inverted trapezoidal section. The sand is accommodated in the inner container body. A guard member is erected almost vertically around the lid to form a peripheral wall.
Thus, the toilet for pets of Patent Document 1 has an inverted trapezoidal shape, so that the toilet becomes unstable when the cat moves on the lid or excretes in a sideways posture. Therefore, it is possible that the cat cannot move or excrete with confidence.
And since the wall stands up almost vertically in the first place, the space to move on the lid is narrow, the cat can not move on the lid so that it is in an ideal posture, the expected posture It is also possible to excrete.

Thus, in the pet toilet described in Patent Document 1, it is doubtful whether a cat can be used without disgusting in the first place.
Further, for example, since no sideways excretion is planned, it is conceivable that feces and urine may adhere to the lid without passing through the excretion hole.
Furthermore, since the cat lacks a sense of stability when it rides on the lid, the cat may hate to use it.

  The present invention has been made in order to solve such a problem, and the cat is used without being disliked. An object of the present invention is to provide a toilet for pet animals that passes through an opening.

As a toilet for pet animals, the inventor has a sand receiving portion for storing sand, a toilet seat installed above the sand receiving portion so that a cat can ride and a hole for excrement falling, and a toilet seat The basic form is to have a peripheral wall standing around the provided area, and if any device is added to this basic form, the cat will not dislike the use of the toilet, and the excrement will surely be released from the hole in the toilet seat when excreted. The present invention has been completed by earnestly studying whether it can fall.
In the following, the problems assumed by the inventor up to the completion of the present invention and the knowledge obtained by the inventor to solve the problem will be described in detail.

What should be done to prevent cats from reluctant to use the toilet? On the contrary, we discussed why cats may be reluctant to use the toilet in conventional toilets.
First of all, even if the cat gets on the toilet seat, in order to evacuate after putting the front leg on the edge of the front of the toilet, the cat on the toilet seat needs to move around on the toilet seat from the front of the toilet There is.
However, in the conventional pet toilet as shown in Patent Document 1, the peripheral wall provided around the toilet seat is erected almost vertically, and the cat is cramped to move on the toilet seat. It is difficult to induce. Therefore, it becomes a factor that a cat dislikes getting on the toilet itself.

  Since it is difficult to guide the circular movement, if a cat on the toilet seat tries to excrete the toilet in the lateral direction, the front leg is hung on the wall or the front leg is placed on the toilet seat. However, even when trying to hang the forefoot on the wall, the conventional pet toilet does not assume such a thing, so the peripheral wall is not cut out except for one part of the front of the toilet, and the forefoot can be hung. Hard to do. Even if the front leg is hung, the conventional toilet for pets does not assume that the cat will be excreted sideways. It may be unstable, and the toilet may be wobbled and the cat will be surprised.

On the other hand, when a cat that faces the toilet in the horizontal direction tries to excrete with its front paws on the toilet seat, it feels tight due to the vertical wall that stands upright, and the cat can excrete with peace of mind. I can't. For example, the width of the hole in the toilet seat can be set wider so that both feet of the cat can ride with room. However, the feces of the cat may not fall out of the hole and adhere to the hole. It will increase.
Thus, in the conventional pet toilet, even if the cat rides on the toilet seat, it is assumed that the cat excretes in a posture with the front foot on the front notch of the toilet, but not so The posture is such that it cannot be excreted comfortably. This makes cats dislike using the toilet itself.

Therefore, if the inventor tried to excrete in the toilet and got on the toilet seat, the inventor would be able to excrete the cat on the toilet seat with peace of mind, and ensure that the excrement would fall out of the toilet seat hole. I thought about what kind of ingenuity is necessary to make it.
The most ideal way is for a cat on the toilet seat to excrete with its forefoot on a notch in the peripheral wall of the front of the toilet. Therefore, although cats riding on the toilet seat will be around walking around on the seat in order to take the attitude, in order to induce its operation, the inventor and the peripheral wall in an oval or long yen shaped cat I thought about making it easier to move around. In addition, in order to eliminate the feeling of pressure of the peripheral wall against the cat moving around, we considered that the inner wall surface of the peripheral wall is inclined outward to create a space between the cat's body and the wall. By doing so, it is possible to prompt the cat to move around without increasing the width of the periphery of the toilet seat.

In addition, even if the cat riding on the toilet seat does not excrete at the ideal position described above, for example, when the cat is excreted in the state of facing the toilet, the cat excretes with confidence, and the excrement remains in the toilet seat. The point of dropping from the hole was considered as follows.
As described above, by tilting the peripheral wall in the outward direction, when the cat tries to excrete sideways, the peripheral wall is not compressed, so the cat can place both feet on the toilet seat. In fact, model experiments using cats have confirmed that cats evacuate with both feet on the toilet seat with the toilet facing sideways. In this way, by inclining the peripheral wall outward, it is possible to excrete in the horizontal direction without increasing the width around the toilet seat hole, and the width around the toilet seat hole is not widened. The possibility of excrement sticking to the toilet seat can also be reduced.

  Thus, the inventor found that inclining the inner wall surface of the peripheral wall in the outward direction can guide the circular movement of the cat riding on the toilet seat and enable proper excretion while facing the peripheral wall I got.

In addition, when the cat tries to excrete in a sideways posture, it is necessary to ensure that the toilet does not become unstable. Then, I thought to make this outer wall function as a customer part that supports the toilet, thereby realizing a stable installation.
Then, it was found that the skirt-like outer wall is configured as a leg portion for supporting the toilet, so that the sand receiving portion into which the sand is put can be shaped in any way. In other words, in the conventional example, since the toilet is supported by the bottom surface of the sand container, the sand container needs to have a function of accommodating the sand and stably supporting the toilet. Therefore, the capacity of the sand accommodating portion becomes larger than necessary, and as a result, it is necessary to put more sand than necessary.
In this regard, the inventor has found that it is possible to reduce the capacity of the sand storage part to the minimum capacity required by separating the sand storage of the toilet from the function of supporting the toilet. Got.

The present invention has been completed on the basis of the knowledge obtained as a result of the above research, and specifically comprises the following configuration.
Each of the various solving means described above has a specific effect, and does not mean that all the solving means must be provided.

(1) A toilet for pet animals according to the present invention has a toilet body having a sand container for containing sand, and an opening for allowing manure to pass therethrough while being detachably installed above the sand container. The toilet body has a circular, elliptical, or oval peripheral wall in a plan view that rises above the position where the toilet seat is installed and has a notch in the front of the toilet. The inner wall surface is formed so as to rise obliquely outward.

(2) Moreover, in the thing as described in said (1), the surrounding wall is curving so that it may dent in the inner wall surface side, It is characterized by the above-mentioned.
By curving the peripheral wall inward, it is possible to effectively prevent the scattered sand from splashing out of the toilet when the cat digs sand with its feet. In addition, by curving the peripheral wall inward, the space in the toilet can be increased without increasing the width of the peripheral edge of the opening of the toilet seat, and the cat moves around on the toilet seat or is excreted facing the wall. It can effectively eliminate the feeling of pressure on the cat when it is. And since it is not necessary to make the width | variety of the opening part peripheral part of a toilet seat wide, it can reduce the possibility that feces and urine will adhere to the opening part peripheral part of a toilet seat by that much.

(3) Further, in those described in the above (1) or (2), the outer peripheral shape and the opening of the toilet seat, a circle, is formed in an oval or long circular, openings periphery on both sides of the該便seat The width is set to be wider than the width of the peripheral edge of the opening at the front and rear portions of the toilet seat.
By widening the peripheral edge of the opening on both sides of the toilet seat, even when the cat excretes sideways, the front paws can be placed comfortably on the peripheral edge of the opening of the toilet seat, making it easy to excrete sideways .

(4) Moreover, in the thing in any one of said (1)-(3), the site | part close | similar to the opening part in the opening part peripheral part of a toilet seat is made into the gentle slope which inclines gently to a plane or an opening part side, These The portion outside the flat surface or the gentle slope is a slope with a steep slope than the gentle slope.
By providing a flat or gentle slope part at the periphery of the opening of the toilet seat and a steeper slope part than these, a part of the toilet seat can function as the inner wall surface of the peripheral wall of the toilet body. It is possible to effectively guide the orbiting movement of the cat on the toilet seat.

(5) Moreover, in the thing in any one of said (1)-(4), it has a support leg which supports a toilet main body, and a part or all of this support leg is a sand accommodating part in planar view. It is provided so that it may be arrange | positioned on the outer side.
It is necessary to support the toilet on the bottom surface of the sand container by providing the support legs for supporting the toilet body so that part or all of the support legs are arranged outside the sand container in plan view. Thus, the volume of the sand container can be set regardless of the toilet support function. Therefore, the volume of the sand container can be set to a small capacity, and a pet animal toilet that can save sand can be realized.
In addition, as a specific example aspect in which the support leg that supports the toilet body is provided so that a part or all of the support leg is disposed outside the sand container in a plan view, a cylinder is provided so as to surround the sand container. The aspect which provides a shape-like leg part, the aspect which notches a part of circumference | surroundings of this cylindrical leg part, the aspect which provides the rib-shaped leg part which protrudes on the outer wall of a sand accommodating part, etc. can be mentioned.

(6) Moreover, in the thing in any one of said (1)-(5), it has an outer wall extended toward the bottom from the top part of a surrounding wall, and this outer wall is a leg part which supports a toilet. It has the function of.
Since the outer wall has a function as a leg, it is not necessary to support the toilet on the bottom surface of the sand container, and the volume of the sand container is set regardless of the toilet support function. Therefore, the volume of the sand container can be set to a small capacity, and a pet animal toilet that can save sand can be realized.
In addition, the outer wall extending downward from the top of the peripheral wall has a function as a leg portion, which is excellent in design.

(7) Moreover, in the thing in any one of said (1)-(6), the width of the widest part in the opening part peripheral part of a toilet seat is A, The toilet seat outer peripheral part in the said wide part when a toilet seat is installed When the horizontal distance of the top of the peripheral wall is D, the length of D is set to be 0.5 to 1.1 times the length of A.
By setting the length of D to be 0.5 times or more of the length of A, the necessary space between the cat and the peripheral wall can be provided without setting the toilet seat opening periphery more than necessary. It can be ensured, and it is easy to put the forefoot on the toilet seat with the cat facing the peripheral wall, and appropriate excretion in the state of facing the peripheral wall can be realized.

(8) Moreover, in the thing in any one of said (1)-(7), when the toilet seat is installed, the horizontal distance of the toilet seat outer peripheral part in the widest part in the opening part peripheral part of this toilet seat, and the top part of a surrounding wall Is D and the height of the peripheral wall is E, the length of D is set to be not less than 0.5 times and not more than 1.1 times the length of E.
By setting the length of D to be not less than 0.5 times the length of E, the inclination angle of the peripheral wall does not become extremely large, and the periphery of the toilet seat opening is the same as described in (7) above. Even if the part is not set wider than necessary, the necessary space can be secured between the cat and the surrounding wall, the front leg can be easily put on the toilet seat with the cat facing the surrounding wall, and the face facing the surrounding wall Appropriate excretion can be achieved.

(9) Moreover, in the thing in any one of said (1)-(8), it has a tool holding part which can hold | maintain a tool in the surrounding wall of the toilet rear part in a toilet main body, and hold | maintains the said tool in this tool holding part Then, at least a part of the tool is set to extend upward from the top of the peripheral wall at the rear of the toilet.
By holding the tool in the tool holding part formed on the peripheral wall at the rear of the toilet, a part of the tool extends upward from the peripheral wall at the rear of the toilet, so that when the cat tries to face the peripheral wall at the rear of the toilet, the tool becomes obstructive Therefore, it is possible to prevent the cat from being excreted while facing the rear of the toilet. Therefore, the posture of excretion of the cat can be limited to forward and sideways, the width of the peripheral edge of the rear part of the toilet seat can be reduced, and therefore the opening can be set large, and the excrement can surely fall from the opening. It becomes possible to do so.

  In the present invention, the toilet body having a sand container for containing sand, and a toilet seat detachably installed above the sand container and having an opening for passing manure, the toilet The main body has a circular, elliptical, or oval peripheral wall in a plan view that rises above the position where the toilet seat is installed and has a notch in the front of the toilet, and the inner wall of the peripheral wall faces outward. Therefore, it is possible to effectively guide the circling movement of the cat riding on the toilet seat of the toilet and to make it excrete toward the front of the toilet. Moreover, in addition to being able to perform such an operation without difficulty, it is possible to allow the cat to be excreted in a posture other than forward-looking, and it is possible to achieve an effect that the cat does not dislike using the toilet.

  FIG. 1 is a perspective view of a pet animal toilet constructed as an optimal cat toilet for a cat as an embodiment of the present invention. 2 is a perspective view showing a state in which the toilet seat for the pet animal shown in FIG. 1 is removed, FIG. 3 is a plan view of the toilet for the pet animal shown in FIG. 1, and FIG. -A line sectional view, FIG. 5 is a sectional view taken along the line BB in FIG. 3, FIG. 6 is a perspective view showing the state of the toilet for pet animals from the bottom side, FIG. 7 is a perspective view showing the use state, FIG. 8 is a plan view of a toilet seat used for a pet animal toilet. Hereinafter, the toilet for pet animals of this Embodiment is demonstrated based on FIGS.

First, the outline of the toilet 1 for pet animals according to the present embodiment will be described. As shown in FIGS. 1 to 5, a toilet body 5 having a sand container 3 for containing sand, and a sand container in the toilet body 5. 3 and a toilet seat 9 having an opening 7 through which manure passes, and the toilet body 5 rises above the position where the toilet seat 9 is installed and the front of the toilet An elliptical peripheral wall 13 having a notch 11 is formed in plan view, and an inner wall surface 15 of the peripheral wall 13 is formed to rise obliquely outward.
Hereinafter, each configuration will be described in detail.

<Toilet seat>
Seat 9, as shown in FIG. 8, a seat frame 17 of a substantially long circular (shape oval) in a plan view length circular opening 7 is formed, is formed on the front portion of the seat frame 17 seat 9 Is formed from a fixing piece 19 for fixing the toilet body 5 to the toilet body 5.
The shape of the opening 7 formed in the toilet seat main body 17 is not similar to the outer peripheral shape of the toilet seat main body 17 (hereinafter simply referred to as “toilet seat main body shape”), and is longer than the toilet seat main body shape. As a result, the width of the opening peripheral portion 21 of the toilet seat body 17 is not uniform but is different.

In this example, A = 76 mm, B = 36 mm, and C = 64 mm, where A is the lateral width of the peripheral edge 21 of the opening, B is the front width, and C is the rear width.
The reason why the width of the horizontal part is set larger than the front part and the rear part in this way is to make the cat have an appropriate urination posture in relation to the shape of the inner wall surface 15 of the peripheral wall 13 of the toilet body 5 described later. However, details on this point will be described later.
In the present embodiment, the ratio of the front width B, the rear width C, and the horizontal width A is as follows: C = 1. 78, B = 2.1, but as the allowable range of the rear width C and the lateral width A with respect to the front width B, when the front width B is 1, C = 1.6 to 1.9 and B = 2.0 to 2.3.

  The peripheral edge 21 of the opening of the toilet seat 9 is a gentle inclined surface toward the opening 7. This is because the sand adhering to the opening peripheral edge 21 and the urine adhering to the opening peripheral edge 21 without passing through the opening 7 slide to the opening side. In addition, a plurality of holes 22 for dropping sand are provided in the peripheral edge 21 of the opening.

  The fixed piece portion 19 includes a rectangular planar portion 23 in plan view and a bent piece portion 25 (see FIGS. 1 and 2) formed by bending downward from the planar portion 23. As shown in FIG. 1, the flat surface portion 23 comes into contact with the bottom surface of the cutout portion 11 of the peripheral wall 13 of the toilet body 5. As shown in FIGS. 1 and 2, the bent piece 25 is formed with a locking hole 27, and the locking hole 27 is locked to the locking portion 29 of the toilet body 5, so that the toilet seat 9 is The toilet body 5 is firmly held.

<Toilet body>
As shown in FIGS. 1 to 5, the toilet body 5 is formed with a sand accommodating portion 3 for accommodating sand at the center, and a step portion for placing the toilet seat 9 on the upper portion of the sand accommodating portion 3. 31 (see FIGS. 2 and 4) is formed over the entire upper periphery of the sand container 3. A vertical wall 33 is formed substantially vertically from the outer periphery of the step portion 31 so as to rise to the height of the toilet seat 9. The vertical wall 33 is continuously inclined to the outside and curved inward. An inner wall surface 15 is formed. Further, an outer wall 35 extending downward from the top of the peripheral wall 13 is formed, and the four corners of the outer wall 35 become leg portions 37 installed on the floor surface when the toilet body 5 is placed on the floor surface. Yes.
The toilet body 5 formed in the shape as described above is made of a resin molded product, and the sand container 3, the step portion 31, the vertical wall 33, and the peripheral wall 13 are integrally formed. When viewed from the side, as shown in FIG. 6, a wide space is formed between the outer surface of the sand container 3 and the outer wall 35.
Below, the peripheral wall 13 which has the main feature points of the toilet main body 5 is demonstrated in detail.

  Although the peripheral wall is substantially elliptical in plan view, as shown in FIG. 2, an inverted trapezoidal notch 11 is formed at the front of the toilet. The bottom of the notch 11 is a flat peripheral wall plane 39. Both side surfaces of the notch portion 11 are inclined portions 41 inclined toward the peripheral wall plane portion 39. The reason why the inclined portion 41 is used is that when the cat hangs the front foot toward the upper side of the peripheral wall 13, the front foot naturally slides on the inclined portion 41 and moves toward the peripheral wall plane portion 39.

[Inner wall surface]
As described above, the inner wall surface 15 is formed so as to be inclined outward and bend inward, and as a result, a space is formed between the cat riding on the toilet seat 9 and the inner wall surface 15. It has come to be. Hereinafter, the size of this space and its meaning will be described.
As shown in FIG. 5, the width of the opening peripheral edge portion 21 on both sides (horizontal portion) of the toilet seat 9 (hereinafter sometimes referred to as “lateral opening peripheral edge width of the toilet seat 9”) is A, and the lower end of the inner wall surface 15. When the length in plan view from the top to the top (hereinafter sometimes referred to as the inner wall horizontal width) is D, A = 76 mm and D = 53 mm are set. Therefore, in this example, the length of D is set to about 0.7 times the length of A.
Thus, by inclining the inner wall surface 15 of the peripheral wall 13 outward, a space is formed at a predetermined ratio with respect to the width of the opening peripheral edge portion 21 of the toilet seat 9. It is possible to induce the cat on board to feel the pressure on the inner wall surface 15 and move around on the toilet seat 9.
The inner wall horizontal width D described above corresponds to “the horizontal distance D between the toilet seat outer peripheral portion and the top of the peripheral wall in the wide portion when the toilet seat is installed” in the present invention.

  Further, as described above, in the present embodiment, the width A of the peripheral opening portion of the toilet seat 9 is set wider than the front and the rear, and this and the inner wall horizontal width D are set to a predetermined value. By making the length or longer, the cat can be excreted sideways, and even if the cat excretes sideways, manure falls appropriately from the opening 7 of the toilet seat 9. That is, by widening the peripheral opening width A of the side opening of the toilet seat 9, even when the cat is turned sideways, the front and rear legs can be placed on the peripheral edge of the horizontal opening of the toilet seat 9, and By setting the wall surface horizontal width D to be equal to or longer than a predetermined length, it is not possible to give a feeling of pressure to a sideways cat, and as a result, the cat can excrete sideways. It falls from the opening 7.

  In this way, the inner wall surface 15 is inclined outward and curved inward so that a space is formed between the cat riding on the toilet seat 9 and the inner wall surface 15. As a result, it is possible to guide the cat's orbital movement and to allow the cat to excrete in a sideways posture in combination with the wide width of the peripheral edge of the side opening of the toilet seat 9.

The reason why the space is defined in relation to the width of the opening peripheral edge 21 of the toilet seat 9 is that the width of the opening peripheral edge 21 of the toilet seat 9 is large, that is, the toilet itself is large, that is, a large cat. This is because the space needs to be widened accordingly.
In the above example, the inner wall surface horizontal width D is about 0.7 times the length of the opening peripheral edge width A of the toilet seat side, but the length of D is 0 of the length of A. If it is 5 times or more, the effect of inducing the cat's orbital movement can be greatly expected as compared with the conventional vertical wall. Moreover, it is more preferable that the length of D is 0.7 times or more of the length of A as in the present embodiment.
Note that the upper limit of the magnification of the length D to the length A is 1.1 times, preferably 1.0 times. If the upper limit value is increased, the size of the toilet body 5 becomes too large and the inner wall surface 15 is too slanted, so that the slope of the inner wall surface 15 becomes too loose and the scattered sand becomes difficult to slide off. . In summary, the range of the magnification of D to the length of A is 0.5 times to 1.1 times, 0.5 times to 1.0 times, and 0.7 times to 1.1 times. , 0.7 times to 1.0 times, and the later described ones can be said to be a more preferable range.

Further, the inner wall horizontal width D has a predetermined meaning in defining the height of the peripheral wall 13 in relation to E (see FIG. 5), so this point will be described below.
The reason why the inner wall horizontal width D is defined in relation to the peripheral wall height E is that the peripheral wall height E becomes large, that is, if the height of the peripheral wall 13 is high, even if the length of D is the same, the inclination of the peripheral wall 13 However, if the height of the peripheral wall 13 is reduced, the inclination of the peripheral wall 13 will be relaxed even if the length of D is the same, so the feeling of pressure on the cat riding on the toilet seat 9 will be different. is there.
When the height of the peripheral wall 13 is E (see FIG. 5), E = 80 mm is set in this example. Therefore, in this example, the inner wall horizontal width D is set to about 0.66 times the length of the peripheral wall height E.

In the above example, the inner wall horizontal width D is about 0.66 times the peripheral wall height E. However, if the length of D is 0.5 times the length of E or more, Compared to the vertical wall, it can be greatly expected to be able to induce the cat's orbital movement. Moreover, it is more preferable that the length of D is 0.66 times or more of the length of E as in the present embodiment.
The upper limit of the magnification of the length D to the length E is 1.1 times, preferably 1.0 times. This is because if the upper limit value is increased, the height of the toilet body 5 becomes too high, and the inclination of the inner wall surface 15 becomes too steep to cause a feeling of pressure on the cat. In summary, the range of the magnification of D to the length of E is 0.5 times to 1.1 times, 0.5 times to 1.0 times, and 0.66 times to 1.1 times. 0.66 times to 1.0 times, and the later-described one can be said to be a more preferable range.

〔outer wall〕
The outer wall 35 extends downward from the top of the peripheral wall 13 downward, and the four corners of the outer wall 35 are leg portions 37 that are installed on the floor surface when the toilet body 5 is placed on the floor surface. Therefore, the toilet body 5 is stably placed in a wide area with respect to the floor surface.
As shown in FIG. 6, when the toilet body 5 is viewed from the bottom side, a large space is formed between the sand container 3 and the outer wall. This means that the volume of the sand container 3 is set small. It means that That is, even if the volume of the sand container 3 is set small, the toilet body 5 can be stably installed on the floor surface.
Thus, since the outer wall 35 is provided in the surrounding wall 13 and this outer wall 35 is made to function as the leg part 37, with the prior art example in which the bottom face of the sand accommodating part 3 became the mounting surface of the toilet main body 5. In contrast, the volume of the sand container 3 can be set regardless of the stable installation of the toilet body 5. For this reason, the effect that the volume of the sand accommodating part 3 can be set as small as possible, and can be set to a free shape is acquired.

  As shown in FIG. 1, FIG. 2, and FIG. 6, the outer wall 35 is formed with a curved portion 43 that curves upward, backward, left, and right, and the curved portion 43 is provided by providing the curved portion 43. When the toilet body 5 is placed on the floor surface, a gap is formed between the toilet body 5 and the toilet body 5 that is placed on the floor surface. Yes.

  As shown in FIG. 7, a tool holding portion 45 for holding a scoop 44 used for sand leveling or the like is formed at the rear portion of the peripheral wall 13. The tool holding portion 45 is formed by providing a recessed portion on the peripheral wall 13 and can be held by inserting the main body portion 49 of the scoop 44 including the handle 47 and the main body portion 49 into the recessed portion. Then, as shown in FIG. 7, in a state where the main body portion 49 is held, the handle 47 is held so as to extend upward from the top portion of the peripheral wall 13. For this reason, even if the cat riding on the toilet seat 9 tries to hang the forefoot on the peripheral wall 13 in a state of facing backward, the handle 47 of the scoop 44 becomes obstructive and it is difficult to hang the forefoot. For this reason, it can prevent that a cat excretes in the state which faced the rear part of the surrounding wall 13, in other words, there exists an effect of encouraging the excretion attitude | position to a cat forward and sideways.

<How to use>
Next, the usage method of the toilet 1 for pet animals which concerns on this Embodiment comprised as mentioned above is demonstrated below.
When the toilet 1 for pet animals is used for a kitten, it is difficult to use the toilet seat 9. Therefore, the toilet seat 9 is removed and used. In this case, it is possible to put a foot on the recessed portion of the peripheral wall 13 formed at the front end of the toilet body 5 and to easily enter the sandbox. In addition, since the surrounding wall 13 is provided in the toilet main body 5, it can prevent that sand scatters out of a toilet.

When the toilet seat 9 is used, the toilet seat 9 is attached to the toilet body 5 as shown in FIG. When the cat uses the toilet with the toilet seat 9 attached, the cat rides on the toilet seat 9 from the front of the toilet, the cat riding on the toilet seat 9 makes a round on the toilet seat 9 and the front leg is cut away in the peripheral wall 13 It excretes so that it may hang on the plane part 23 of the toilet seat 9 installed on the surrounding wall plane part 39 of the part 11. FIG. When the cat excretes in this posture, manure falls from the opening 7 of the toilet seat 9 to the sandbox.
Thus, in the toilet 1 for pet animals of this Embodiment, since the space is provided between the opening peripheral part 21 of the toilet seat 9 and the surrounding wall 13, the cat who got on the toilet seat 9 can easily carry out the toilet seat 9 It is easy to make a predetermined posture around the top.

  If a cat tries to excrete in a state of facing sideways before making a round after riding on the toilet seat 9, there is a predetermined space between the peripheral wall 13 and the cat. It will be excreted in the state of being placed at the peripheral edge of the opening. Even if excreted in this posture, manure falls from the opening 7 of the toilet seat 9 to the sandbox. And even when the cat is taking a posture of excretion in a sideways state, the outer wall 35 forms a leg portion 37 with a divergent shape, so that the toilet body 5 is stably placed on the floor surface. There is no wobbling.

Further, when the cat faces the rear wall of the peripheral wall 13, as shown in FIG. 7, the handle 47 of the scoop 44 becomes an obstacle, so that excretion in the state of facing the rear wall 35 is prevented.
That is, the cat on the toilet seat 9 excretes forward and sideways, and excrement falls from the opening 7 of the toilet seat 9 into the sandbox regardless of the posture of excretion.

  In the embodiment described above, an example in which the outer wall 35 continuous from the top of the peripheral wall 13 is formed in order to stably install the toilet body 5 is different from the outer wall 35 continuous from the top of the peripheral wall 13. A separate leg may be provided on the peripheral wall 13. In this case, for example, a leg portion fixed to the toilet body 5 and extending outward from the inner wall surface 15 in a plan view may be provided.

In the above embodiment, the outer wall 35 extending downward from the top of the peripheral wall 13 is formed, and the outer wall 35 functions as a leg portion that supports the toilet body 5. Although shown, for example, an outer wall 35 that spreads in the form of a skirt may be provided so as to be continuous with the lower portion of the peripheral wall 13. Further, as shown in FIG. 10 which is a cross-sectional view of FIGS. 9 and 9, an outer wall 35 functioning as a leg portion is provided so as to surround the sand accommodating portion 3, and is provided without spreading in a skirt shape. An aspect may be sufficient.
Further, in the above-described embodiment, the inner wall surface 15 rises obliquely toward the outside and is curved so as to be recessed toward the inner wall surface side. However, as shown in FIGS. The wall surface 15 may be configured to rise obliquely outward without being recessed toward the inner wall surface side.

  Further, as shown in FIGS. 9 and 10, a portion 9a near the opening in the toilet seat 9 is a flat or gentle gentle slope inclined toward the opening, and a portion 9b outside the flat or gentle slope is flat or loose. You may make it an inclined surface of a steep slope rather than a slope.

  In the above embodiment, the shape of the peripheral wall 13 in plan view is described by taking an ellipse as an example. However, the shape of the peripheral wall in plan view of the present invention is not limited to this, and the cat moves around. For example, the shape may be a circle (see FIGS. 9 and 10) or an ellipse.
