Description

The present disclosure relates to veterinary toilets for receiving excrement from dogs and the like.

For example, a liquid-permeable top sheet and a liquid-impermeable back sheet, and an absorbent disposed between the top sheet and the back sheet for treating excrement of animals such as dogs housed indoors. An absorbent sheet as an absorbent article including a body is widely known.
In this type of absorbent sheet, when an animal rides on the upper surface of the absorbent sheet, it may be displaced and wrinkled or turned up. Therefore, for example, as in the animal litter box shown in Patent Document 1, a panel holding part is provided. By disposing and pressing the constituent fixing member on the upper surface side of the absorbent sheet, it is possible to prevent the absorbent sheet from being displaced or turned over.

The invention disclosed in Patent Document 1 includes a lower container having an excrement container for accommodating excrement and having an open upper surface,
A disposable liquid permeable panel arranged to cover the upper part of the excrement container,
A panel support portion disposed between the lower container and the liquid permeable panel to support the liquid permeable panel,
A system toilet for dogs, comprising: a panel pressing portion that presses at least a part of the vicinity of the peripheral edge of the liquid permeable panel from the upper surface side of the liquid permeable panel.

The conventional veterinary toilet disclosed in Patent Document 1 has a configuration in which a fixing member that constitutes a panel pressing portion is fixed from above so as to surround an excretion region for excretion of animals. In addition, the animal litter box is configured such that the animal can enter the animal litter box in the entry direction from an entry part provided on the fixing member for the animal to enter. Further, the fixing member is configured to have a uniform width regardless of whether it is the entrance portion or a portion other than the entrance portion.

JP, 2013-202028, A

The inventors of the present disclosure have made it possible for animals, such as dogs, that are housed indoors to have an absorbent sheet or the like arranged underneath via a flexible member such as a plastic panel or a hard member. We obtained the knowledge about recognizing the softness-sensitive part such as the sex sheet as the excretion region. In addition, the inventors of the present disclosure have a habit of excreting when one or more of the four limbs land on a part recognized by the animal as an excretion area when the animal excretes in an animal litter box. Got knowledge about having.
According to the above findings, in the conventional animal litter box as described in the above-mentioned Document 1, when the animal is excreted, the animal enters the animal litter box from the entry part with the front leg, and the animal is If the front leg lands on the part recognized as the excretion area, it may be excreted. However, in the conventional animal litter box, if the animal is not guided to the back side in the approach direction of the animal litter box, even if the animal's front leg lands in the excretion area, the animal excrement device is used as the animal litter box. There is a possibility that the animal is likely to excrete without being stored inside, and the excrement of the animal may leak out of the animal litter box.
On the other hand, in order to solve the above problems, in the animal litter box, if the length of the width of the fixing member is uniformly lengthened, the animal excretion region until the animal enters the back side of the animal litter entry direction. Cannot be reached, and as a result, it becomes easier to guide the animal to the rear side in the approach direction of the animal litter box. However, in such an animal litter box, since it is necessary to secure the width of the fixing member, it becomes difficult to secure the area ratio of the excretion region with respect to the animal litter box.
Further, conversely, the width of the fixing member is shortened, or the animal litter box is configured without a part of the fixing member, more specifically, with the entrance portion with the excretion region sandwiched therebetween. If the structure is not provided with the fixing members in the parts arranged so as to face each other, this structure may cause the displacement of the excretion region, and animal excrement may easily leak out of the animal litter box.
Therefore, the present disclosure suppresses the displacement of the excretion region and facilitates ensuring the area ratio of the excretion region with respect to the animal litter box, and easily guides the animal to the back side in the entry direction of the animal litter box. It is an object of the present invention to provide an animal litter box in which the excrement of the above does not easily leak outside the animal litter box.

Therefore, the animal litter box according to the present disclosure is
A fixing member for fixing the absorbent sheet, the absorbent sheet is exposed, the animal litter box comprising an excretion region for the animal to excrete,
The fixing member has an approaching direction of the animal, and has an entering portion for the animal to enter, and a non-entering portion other than the entering portion,
The non-entry portion is at least arranged so as to face the entry portion with the excretion region interposed therebetween,
The length of the approaching portion in the approaching direction is longer than the length in the approaching direction of a portion of the non-entrying portion facing the approaching portion,
It is characterized by

According to the present disclosure, while suppressing the displacement of the excretion region and easily ensuring the area ratio of the excretion region with respect to the animal litter box, it is easy to guide the animal to the rear side in the entry direction of the animal litter box, It is possible to provide an animal litter box in which the excrement of the above does not easily leak outside the animal litter box.

The length of the approaching portion in the approaching direction is longer than the length in the approaching direction of a portion of the non-entrying portion facing the approaching portion,
The animal toilet.

In the animal litter box of the present aspect, since the length of the entry portion in the entry direction is configured to be longer than the length of the part of the non-entry portion that faces the entry portion in the entry direction, the length of the entry portion in the entry direction is long. However, the excretion region is arranged on the far side in the approach direction as compared with the case where the length of the non-entrance part facing the approach part is equal to the length in the approach direction. Therefore, it becomes easy to guide the animal from the entry portion to the back side in the entry direction by utilizing the habit of the animal approaching until the front leg reaches the excretion region. As a result, in the animal litter box of the present aspect, when the front leg of the animal lands on the excretion region, the animal excrement is easily excreted in a state where the animal excrement device is housed in the animal litter box, so that the animal excrement is Hard to leak out of the animal toilet.
Further, since the animal litter box of the present aspect has the above-described configuration, the length of the non-entry portion of the non-entry portion facing the entry portion in the entry direction is the length of the entry portion in the entry direction while fixing the absorbent sheet. It is easier to secure the area ratio of the excretion region with respect to the animal litter box, as compared with the case of being configured in the same manner.
Furthermore, since the animal litter box of this aspect has the non-entry part in the fixing member in the part other than the entry part, it guides the animal to the rear side in the entry direction of the animal litter box, and the stress due to the body pressure of the animal is eliminated. Even if it reaches the area, the absorbent sheet is fixed by the non-entry portion, so that the displacement of the absorbent sheet or the excretion area where the absorbent sheet is exposed is easily suppressed.
As described above, the animal litter box of the present aspect, while facilitating the positional deviation of the excretion region and ensuring the area ratio of the excretion region with respect to the animal litter box, keeps the animal in the approach direction of the animal litter box. Easy to guide to the back side, and animal excrement is unlikely to leak out of the animal litter box.

Since the animal litter box of this aspect includes the entry part having a predetermined configuration, even if the animal cannot be guided to the far side in the entry direction of the animal litter box and the animal excretes on the entry part. It is possible to guide the excrement to the excretion region by the inclination of the entrance portion, and make it difficult for the excrement of the animal to leak out of the animal litter box.

[Aspect 5]
The animal litter box further comprises a bottom tray having a mounting portion for mounting the absorbent sheet,
The animal litter box according to any one of aspects 1 to 4.

Since the animal litter box of the present aspect further includes a bottom tray having a predetermined configuration, the absorbent sheet can be stably arranged on the bottom tray, and excrement of the animal is used for the animal while suppressing displacement of the excretion region. You can prevent it from leaking out of the toilet.

[Aspect 6]
The animal litter box further has a plurality of openings, and further comprises a cover member for covering the absorbent sheet arranged in the excretion region.
The animal litter box according to any one of aspects 1 to 5.

Since the animal litter box of this aspect includes the cover member having a predetermined configuration, the absorbent sheet is unlikely to be displaced from the position before entering the animal, even when the animal enters the animal litter box. Therefore, the animal litter box of the present aspect can prevent the excrement of the animal from leaking out of the animal litter box while suppressing the displacement of the excretion region.

[Aspect 7]
The animal litter box further includes a wall member in at least a part of a portion circumscribing an edge of the non-entry portion that is not in contact with the excretion region.
The animal litter box according to any one of aspects 1 to 6.

Since the animal litter box of this aspect further includes a wall member at least at a part of the outer edge of the non-entry part, an animal that has entered the back side of the animal litter direction in the approach direction is likely to stay at the back side in the approach direction. .. Therefore, the animal litter box of this aspect can prevent animal excrement from leaking out of the animal litter box.

Hereinafter, preferred embodiments of the animal litter box according to the present disclosure will be described in detail with reference to the drawings.

The direction from left to right) and the second approach direction E2 (direction parallel to the second direction Y in FIG. 3 and upward from bottom in FIG. 3).

[Fixing member]
As shown in FIG. 3, the fixing member 3 in the animal litter box 1 according to the present embodiment is formed in a substantially square frame shape in plan view. Further, as shown in FIG. 2, the fixing member 3 constitutes the uppermost surface of the animal litter box 1 and exposes a part of each of the cover member 5 and the absorbent sheet 7 arranged on the lower surface side thereof. It is configured.

In the present embodiment, as shown in FIGS. 1 and 3, the fixing member 3 is divided into a first entry portion 13, a second entry portion 15, a first non-entry portion 17, and a second non-entry portion 19. .. As shown in FIG. 3, in the animal litter box 1, the first entry portion 13, the excretion region 11, and the first non-entry portion 17 are arranged in this order in the first entry direction E1. Further, in the animal litter box 1, the second entry portion 15, the excretion region 11, and the second non-entry portion 19 are arranged in this order in the second entry direction E2.

In the present embodiment, as will be described later, each of the first entry portion 13 and the second entry portion 15 has a gentler slope than each of the first non-entry portion 17 and the second non-entry portion 19, The animal A is configured so that the animal A can enter the animal litter box 1 more easily than the first non-entry portion 17 and the second non-entry portion 19.

Further, in the present embodiment, as shown in FIG. 3, the fixing member 3 has an inner edge 21 and an outer edge 23, each of which has a substantially square shape in a plan view. The outer edge 23 of the fixing member 3 forms the contour of the fixing member 3, and the inner edge 21 is a portion of the animal litter box 1 that exposes the excretion region 11 from the fixing member 3.

In the present embodiment, the length L1 of the first approach portion 13 extending in the first approach direction E1 and the length L2 of the second approach portion 15 extending in the second approach direction E2 are each 340 m. Further, the length L3 of the first non-entry portion 17 extending in the first approach direction E1 and the length L4 of the second non-entry portion 19 extending in the second approach direction E2 are each 150 mm. However, the size of the fixing member in the present disclosure is not limited to the aspect of the above-described embodiment, as long as the length of the entry portion in the entry direction is longer than the length of the non-entry portion in the portion facing the entry portion in the entry direction. The size can be appropriately changed according to the size of the animal to which the animal litter box is used.

The term "animal" in the present disclosure refers to dogs, cats, rabbits, ferrets, monkeys, and other animals that can generally be left free in the room, but the animal litter box according to the present disclosure can be used. As long as it exists, its kind and size are not limited in any way. However, the animal litter box according to the present disclosure can be particularly preferably used for pet small indoor dogs that require toilet training.

In addition, the entry part and the non-entry part of the fixing member according to the present disclosure can be partitioned according to the ease with which an animal can enter the animal litter box. The criterion for distinguishing between the entry portion and the non-entry portion is, for example, the height of the fixing member (a portion having a relatively low height in the fixing member is configured as an entry portion, and a portion having a relatively high height is configured as a non-entry portion. By doing so, it is possible for the animal to enter the animal litter box more easily from the non-entry part than from the non-entry part.) The presence or absence of a physical barrier (for example, as shown in the second embodiment described later). As in the aspect, by providing a physical barrier or the like on at least a part of the portion circumscribing the edge that is not in contact with the excretion region of the non-entry portion in the animal litter box, the It is possible that the animal can enter the animal litter box more easily from the entry part.), the difference in slope between the fixing members (the slope at the entrance part is gentler than the slope at the non-entry part). Therefore, it is possible that the animal can enter the animal litter box more easily from the non-entry part than from the non-entry part).

In the present embodiment, the length L1 of the first approach portion 13 in the approach direction E1 is set to be longer than the length L3 of the portion of the first non-entrance portion 17 facing the first approach portion 13 in the approach direction E1. Is configured. Further, the length L2 of the second approach portion 15 in the approach direction E2 is configured to be longer than the length L4 of the second non-entrance portion 19 facing the second approach portion 15 in the approach direction E2. ing. This is from the viewpoint of achieving the operational effects of the animal litter box according to the present disclosure. More specifically, the action and effect of the animal litter box according to the present disclosure will be described below, in comparison with the conventional animal litter box.

FIG. 5: is a figure which shows typically an example of the usage aspect of the animal litter box 1 which concerns on 1st Embodiment of this indication. Further, FIG. 7 is a diagram schematically showing an example of the usage of the animal litter box in the conventional technique.

The animal litter box 1'in the prior art shown in FIG. 7 is configured such that the lengths L1' to L4' of the respective entrance portions 25 extending in the approach directions E1' to E4' are uniform. The animal litter box 1'in the prior art is configured to be able to enter the animal litter box 1'through any of the entry portions 25 provided on the four sides of the substantially square fixing member 3'. However, for the sake of convenience, a case will be described in which the animal A'enters the animal litter box 1'through the entry portion 25 provided in the lower portion of the fixing member 3'in FIG. In this case, the animal A'can enter the animal litter box 1'with the approach direction E2' being parallel to the second direction Y in Fig. 7 and upward from the bottom in Fig. 3.

According to the habit of the animal approaching the front leg until reaching the excretion region as described above, in the conventional animal litter box 1′, as shown in FIG. In some cases, the animal entered into the animal litter box 1'through the entry part 25 at F1' and the animal A'excreted when the front leg F1' landed on the part recognized as the excretion area 11'. In that case, the excrement of the animal A'or the rear leg F2' of the animal does not fit into the animal litter box 1', and the animal A'is likely to be excreted. There was a risk that it would leak out of 1'.

On the other hand, in the animal litter box 1 according to the present embodiment, as shown in FIG. 5, the length L1 of the first entry portion 13 in the entry direction E1 faces the first entry portion 13 of the first non-entry portion 17. It is configured to be longer than the length L3 of the portion in the approach direction E1. Further, the length L2 of the second approach portion 15 in the approach direction E2 is configured to be longer than the length L4 of the second non-entrance portion 19 facing the second approach portion 15 in the approach direction E2. ing.
The case where the animal A enters the animal litter box 1 from the second entry part 15 in the approach direction E2 will be described. In the animal litter box 1 of the present embodiment, as shown in FIG. In some cases, the front leg F1 may enter the animal litter box 1 from the second entry portion 15 and be excreted when the front leg F1 lands on a portion where the animal A recognizes the excretion region 11. In the animal litter box 1, as described above, the length L2 of the second entry portion 15 in the entry direction E2 and the length of the second non-entry portion 19 facing the second entry portion 15 in the entry direction E2. Since the animal A has a predetermined relationship with the length L4, the animal A is compared with the conventional animal litter box 1′ when the front legs F1 of the animal A land on the excretion region 11 in which the animal can be excreted. As a result, the animal toilet 1 is likely to be guided deeper in the approach direction. That is, in the animal litter box 1 according to the present embodiment, the length of the entry portion in the entry direction is equal to the length of the non-entry portion of the portion facing the entry portion in the entry direction, The excretion region 11 is arranged on the back side in the approach direction E2. Therefore, it becomes easy to guide the animal A from the second entry portion to the back side in the entry direction E2 by utilizing the behavior of the animal that enters until the front leg F1 reaches the excretion region 11. As a result, in the animal litter box 1, when the front leg F1 of the animal lands on the excretion area 11, the animal can be easily excreted in a state where the animal excrement device or the rear leg F2 of the animal is housed in the animal litter box 1. Animal excrement U is unlikely to leak out of the animal litter box 1.
In the above, the case where the animal A enters the animal litter box 1′ from the second entry part 15 in the entry direction E2 has been described, but the animal A enters the animal litter box 1 from the first entry part 13 in the entry direction E1. Even in the case, the same effect as above can be obtained.

Further, since the animal litter box 1 has the above-mentioned configuration, the portion of the first or second non-entry part 17, 19 facing the first or second entry part 13, 15 while fixing the absorbent sheet 7. Of the first or second approach direction E1, E2 (L3, L4) is configured to be equal to the length (L1, L2) of the first or second approach section 13, 15 in the approach direction E1, E2. The area ratio of the excretion region 11 to the animal litter box 1 is easier to secure than in the case of the above. Furthermore, since the animal litter box 1 has the first non-entry part 17 and the second non-entry part 19 in the part other than the first entry part 13 and the second entry part 15 in the fixing member 3, the animal A The absorbent sheet 7 is fixed by the first non-entry part 17 or the second non-entry part 19 even if the stress is generated in the excretion region 11 by being guided to the back side of the toilet 1 in the entry direction and the body pressure of the animal A is applied. Therefore, it is easy to suppress the displacement of the absorbent sheet 7 or the excretion region 11 where the absorbent sheet 7 is exposed.

As described above, the animal litter box 1 allows the animal A to enter the animal litter box 1 while easily suppressing the displacement of the excretion area 11 and ensuring the area ratio of the excretion area 11 to the animal litter box 1. The effect that the excrement U of the animal A is less likely to leak out of the animal litter box 1 is obtained because the excrement U of the animal A is easily guided to the back side in the direction.

In the animal litter box 1 according to the present embodiment, each of the lengths (L1, L2) of the first approach portion 13 in the first approach direction E1 and the second approach portion 15 in the second approach direction E2 is in the excretion region 11, It is 40% of the length (L5) extending in the direction parallel to the first approach direction E1 of the first approach portion 13 and the direction parallel to the second approach direction E2 of the second approach portion 15, respectively. However, in the animal litter box according to the present disclosure, the length in the entry direction of the entry part is not limited to the above, and the maximum value of the length of the excretion region extending in the direction parallel to the entry direction of the entry part, It is preferably 10 to 100%, more preferably 20 to 80%, and even more preferably 25 to 50%.

According to such a configuration, the animal litter box does not have such a configuration because the entry portion has a length in the entry direction of a predetermined ratio with respect to the maximum value of the length of the excretion region extending in the predetermined direction. Compared with the animal litter box, it is easier to guide the animal to the far side in the approach direction of the animal litter box, and even if it is not possible to guide the animal to the far side in the approach direction of the animal litter box, the animal A Can be excreted on the entry site. Therefore, the animal litter box can prevent animal excrement from leaking out of the animal litter box.

Note that the fixing member in the present disclosure can be configured using various materials such as wood, metal, and plastic. Among these materials, it is preferable to use plastic because there is no problem of generation of odor due to infiltration of excrement into the material or corrosion of excrement. As the plastic, various materials such as polyethylene, polypropylene, vinyl chloride resin, polystyrene, ABS resin, AS resin, polyester resin, (polyethylene terephthalate, etc.), polyamide resin, polycarbonate resin can be used.

Further, in the animal litter box of the present disclosure, it is preferable that the length of the entry portion in the entry direction is configured to be longer than the distance between the front leg and the hind leg of the animal that is the target of use of the animal litter box.

In the present disclosure, the distance between the front and rear legs of the animal is the distance between the center of gravity of the ground contact surface of the left front leg and the center of gravity of the ground contact surface of the left rear leg of the animal, with the animal resting on the ground contact surface. And the distance between the center of gravity of the ground contact surface of the right front leg and the center of gravity of the ground contact surface of the right hind leg of the animal.

According to this configuration, in the animal litter box of the present disclosure, since the entry portion is configured to be longer than the lengths of the front leg and the hind leg of the animal to be used, the animal is placed in the entry direction of the animal litter box. It can be guided to the inner side of the animal to suppress excrement of animal excrement outside the animal litter box. Therefore, the animal litter box of the present disclosure can prevent animal excrement from leaking out of the animal litter box.

In the present embodiment, as shown in FIGS. 1 and 3, the fixing member 3 is provided so as to surround four sides of the outer edge of the excretion region 11. According to such a configuration, the absorbent sheet 7 is easily fixed, and the displacement of the absorbent sheet 7 or the excretion region 11 where the absorbent sheet 7 is exposed is easily suppressed.
In the present disclosure, the term “surrounding” the target object (fixing member or the like) around the target object (excretion region or the like) means that the target object directly or indirectly in a portion of 80 to 100% of the outer edge of the target object. It means making external contact.

In addition, in the animal litter box according to the present disclosure, the fixing member is not limited to the above-described aspect as long as the non-entry portion is disposed so as to face at least the entry portion with the excretion region sandwiched therebetween. For example, the entry part and the non-entry part of the fixing member do not have to extend continuously. Further, when the animal litter box has a quadrangular shape in a plan view, the fixing member does not necessarily need to be present on four sides, and the fixing member may be present on two opposite sides or three sides.

In the present embodiment, as shown in FIG. 4, each of the first entrance portion 13 and the second entrance portion 15 is gently inclined and is configured such that the height H decreases as it approaches the excretion region 11. ing. In the present disclosure, the height of the object (entrance portion, wall member described later) refers to the distance in the thickness direction Z between an arbitrary point on the upper surface of the object and the placement surface of the animal litter box.
With such a configuration, the animal litter box 1 cannot guide the animal A to the inner side of the animal litter box 1 in the entry directions E1 and E2, and the animal A is excreted on the first entry part 13 or the second entry part 15. Even if it has happened, the excrement U is guided to the excretion region 11 by the inclination of the first entry part 13 or the second entry part 15 so that the excrement U of the animal A does not easily leak out of the animal litter box 1. You can

In the present disclosure, the gradient difference between the outer edge and the inner edge at the entrance of the fixing member is preferably 2 to 30 mm, more preferably 5 to 15 mm. If the animal cannot be guided deeper in the direction of entry of the animal litter box and the animal is excreted on the first entry part or the second entry part, efficiently guide the excrement to the excretion area. Because.

[Excretion area]
