Description

The present invention relates to a toilet mat cover for fixing an absorbent sheet used in a pet toilet to a pet toilet.

In recent years, pets such as dogs and cats are increasingly kept indoors. The problem with keeping pets indoors is the treatment of excretion. Fortunately, these pets are excreted in a fixed place by so-called "discipline". Therefore, pet toilets that are mainly kept indoors have been proposed.

Litter boxes are used with absorbent sheets that absorb excrement (especially urine). Pets, on the other hand, do not seem to understand the meaning of using absorbent sheets. Therefore, the pet toilet needs to have a function of holding the absorption sheet in an unfolded state even if the pet moves freely.

Patent Document 1 discloses a dog sheet in which an absorbent sheet is placed on a support base, a mesh sheet is further placed, and then the frame and the support base are fixed to hold the absorbent sheet in an expanded state. There is. Here, since the cross sections of the horizontal and vertical bars are formed in an upward convex shape in the bar portion of the lattice of the net-like sheet, urine easily flows to the lower absorption sheet, and the absorption sheet is wrinkled by the movement of the dog. It is said that it does not move.

Patent Document 2 discloses a pet toilet in which two absorbent sheets can be fixed side by side. Here, too, a frame member is disclosed in which the absorption sheet is placed on a tray portion provided with a peripheral wall erected on the bottom surface and the peripheral edge, and the edge portion of the absorption sheet is fixed to the tray. Further, Patent Document 2 also discloses a cover plate material in which a large number of holes are formed to protect the surface of the absorbing sheet.

Patent Documents 1 and 2 can certainly hold the absorbent sheet in an unfolded state even against careless movements of a pet (dog). In addition, there is a net-like fixture that fixes the absorption sheet, and it is considered that it can be suitably used for the treatment of urination.

However, these patent documents do not give any consideration to defecation. The grid-like fixture for fixing the absorbent sheet is not disposable because it is molded of resin or the like. Further, since the fixture is placed between the absorption sheet and the stool, the stool cannot be processed together with the absorption sheet. As a result, the stool on the fixture must be treated by wiping it off. However, the grid-like fixture has a problem that feces tend to remain in the grid, and it takes time and effort for washing such as washing with water each time.

Further, when the lattice is made of resin, if the space between the through holes is widened, sink marks occur and dents are formed. As a result, there is also a problem that urine remains on the surface of the fixture.

The present invention was conceived in view of the above problems, and even if it is a grid-like or mesh-like absorption sheet fixture, feces are less likely to remain, and urine is less likely to remain on the surface and fall onto the absorption sheet. It provides an easy toilet mat cover and a pet toilet with it.

More specifically, the toilet mat cover according to the present invention
Plate-shaped body and
A plurality of through holes formed in the main body,
On the surface that receives the excrement of the pet, a protrusion is provided between the through holes .
The main body is substantially rectangular, and is characterized in that leg members that are detachably attached are arranged on the side surfaces of at least two corners.

In addition, the pet toilet according to the present invention is
With the above toilet mat cover,
Tray part and
It is characterized by having a fixing means for fixing the toilet mat cover and the tray portion to each other.

The toilet mat cover according to the present invention is a plate-shaped member in which a large number of through holes called a lattice shape or a mesh shape are formed, and since protrusions are provided between the through holes, the protrusions support feces and penetrate. It has a structure that makes it difficult to enter the hole. Therefore, after removing the stool, it can be cleaned up cleanly by wiping. In addition, the protrusions between the through holes make it easy for urine to flow into the through holes, and urine does not easily remain on the surface of the toilet mat cover.

It is a figure which shows the conventional pet toilet. It is a figure which shows the structure of the toilet mat cover which concerns on this invention which is adapted to the pet toilet of FIG. It is a figure which shows the back surface of the toilet mat cover which concerns on this invention shown in FIG. FIG. 3 is a diagram showing a pet toilet according to the present invention in which the conventional pet toilet of FIG. 3 and the toilet mat cover according to the present invention shown in FIG. 4 are combined. It is a figure which shows the conventional toilet for pets and the toilet mat cover which concerns on this invention to match. FIG. 7 is a diagram showing a pet litter box according to the present invention, which is composed of a conventional pet litter box and a toilet mat cover according to the present invention of FIG. 7. It is a figure which shows the conventional pet litter box, the toilet mat cover which concerns on this invention corresponding to it, and the pet litter box which concerns on these.

The toilet mat cover and the pet toilet according to the present invention will be described below with reference to drawings and examples. The following description exemplifies one embodiment and one embodiment of the present invention, and the present invention is not limited to the following description. The following description can be modified without departing from the spirit of the present invention.

FIG. 1A shows a perspective view of the toilet mat cover 10 according to the present invention. FIG. 1B is a partially enlarged view of FIG. 1A. The main body 10a of the toilet mat cover 10 has a plate-like shape. The surface shape is not particularly limited and may be circular, oval or rhombic, but the convenience of a rectangle is high. This is because the absorbent sheet used for pet toilets is often rectangular. Even if the four corners are rounded, they are included in the rectangle in this specification.

With reference to FIGS. 1 (a) and 1 (b), a plurality of through holes 12 are formed on the surface. The toilet mat cover is meaningless in a hole through which the pet's feet can pass, as the absorbent sheet placed underneath needs to be protected from the pet's free movement. Further, if the through hole 12 is too small, the excreted urine does not smoothly flow to the lower absorption sheet. Therefore, the through hole 12 has a suitable size. It is preferably about 5 mm to 20 mm square (or diameter).

If the distance 12d between the through hole 12 and the through hole 12 is long, urine will accumulate on the surface. On the other hand, if it is too short, it will be difficult to wipe off the stool residue. It is preferable that there is a length between the through hole 12 and the through hole 12 so that a flat surface 12f can be formed. This is because if the flat surface 12f is formed between the through holes 12, it is easy to wipe it clean even if the toilet mat cover 10 is defecated. Therefore, the distance 12d between the through holes 12 is preferably 1 mm to 5 mm.

Further, it is desirable that the opening edge 12oe of the through hole 12 is chamfered. This is because urine easily flows into the through hole 12. It is more desirable that the chamfering process is a curved surface processing having a curvature.

The through holes 12 are preferably arranged in a uniform vertical and horizontal grid pattern over the entire surface of the main body 10a. When arranged in a vertical and horizontal grid pattern, a space 12s wider than the distance 12d between the through holes 12 which are in an oblique positional relationship and the adjacent through holes 12 can be formed, and the protrusion 14 described later can be formed. This is because there is a place to form.

More specifically, in FIG. 1B, the through holes 12e1 to the through holes 12e4 are referred to. The through hole 12e1, the through hole 12e2, and the through hole 12e3 are in an adjacent positional relationship. On the other hand, the through hole 12e1 and the through hole 12e4 are in an oblique positional relationship. A space 12s wider than the adjacent distance 12d between the through holes 12 is formed between the through holes 12e1 and the through holes 12e4.

In the toilet mat cover 10 according to the present invention, it is not excluded that the through holes 12 are arranged according to a rule other than the grid pattern. Further, it is not necessary to uniformly arrange the through holes 12 over the entire surface 10f of the toilet mat cover 10. That is, the arrangement of the through holes 12 may have a different arrangement pattern depending on the location.

A protrusion 14 is formed in this space 12s. FIG. 2 shows a cross section taken along the line AA shown in FIG. 1 (b). The protrusion 14 is a portion protruding from the surface 10f of the main body 10a (see FIG. 1A) of the toilet mat cover 10. Here, the surface 10f of the main body 10a may be a surface on which the opening 12o of the through hole 12 is formed. That is, the top 14t of the protrusion 14 is located higher than the opening 12o of the through hole 12.

The height 14h of the protrusion 14 is preferably about 1/10 to 1/2 of the maximum diameter of the through hole 12. If it is too high, it will be difficult to wipe off the stool attached to the root side of the protrusion 14, and if it is too low, the stool cannot be supported. For the same reason, the protrusion 14 is preferably configured with a smooth slope. In particular, the top 14t portion should have a rounded curve.

As described above, the toilet mat cover 10 according to the present invention may have a through hole 12 and a protrusion 14. It is more preferable that the protrusion 14 is higher than the opening 12o of the through hole 12. By having this form, urine flows into the through hole 12 according to the inclination of the protrusion 14, so that it is unlikely to remain on the surface 10f of the main body 10a. On the other hand, the stool is supported by the protrusion 14 so that it can be easily wiped off later. Further, since the space between the through holes 12 is formed by a flat surface 12f, wiping is further facilitated. As a result, the cleaning interval of the toilet mat cover 10 can be lengthened, and management becomes easier.

Further, when the toilet mat cover 10 is made of resin, sink marks of the resin do not occur between the through holes 12 (the portion corresponding to the space 12s), so that urine does not remain on the surface of the toilet mat cover 10. When the toilet mat cover 10 is made of resin, it is preferably white or a color close to white. This is because the dirt is conspicuous, so it is easy to understand the necessity of cleaning.

More specific forms of the toilet mat cover of the present invention may have several variations depending on the form of the pet toilet used. An example of modification of the toilet mat cover according to the present invention according to the variation is shown below. Of course, the toilet mat cover according to the present invention is not limited to the following examples.

Further, the pet toilet according to the present invention can be configured in combination with a conventional pet toilet or a part thereof. In such a case, the conventional pet toilet or a part thereof constitutes either or both of the tray portion and the fixing means of the pet toilet according to the present invention.

The pet toilet according to the present invention has a fixing means for fixing the toilet mat cover and the tray portion according to the present invention, and the toilet mat cover and the tray portion according to the present invention. The toilet mat cover according to the present invention has at least the characteristics of the toilet mat cover 10 described above. The tray portion is a portion having a surface on which the absorption sheet is placed. Further, the fixing means is for fixing the tray portion and the toilet mat cover according to the present invention, and the form thereof is not particularly limited. It is also desirable that the absorbent sheet can be fixed at the same time.

As a conventional pet toilet, there is a type shown in FIG. FIG. 3A is an overall view, and FIG. 3B is a partially enlarged view of FIG. 3A. The pet litter box 1 according to the present invention in which the conventional pet litter box 50 is combined with the toilet mat cover according to the present invention will be described below. The conventional pet toilet 50 has a substantially rectangular shape made of silicone. Therefore, it is flexible and has a so-called mat-like shape. The floor 51 is formed of a flat surface. A vertical wall 53 may be formed on the edge portion 52. Further, notches 54 are formed at least at the four corners.

With reference to FIG. 3B, the cut portion 54 is a portion in which the cut 55 is provided on a surface formed at a position higher than the floor 51. This surface does not have to be particularly horizontal and may be inclined. The thickness of the notch 54 may be substantially the same as the thickness of the floor 51. The notch 55 is composed of a crevice 56 that penetrates the silicone at the notch 54. The notch 55 may have at least one crevice 56. However, it is preferable to provide the notch 55 at two or more crevices 56 in which the midpoints of each are combined.

When two or more crevices 56 are stacked, a plurality of movable pieces 56a are formed. When an object is inserted into the notch 55, the movable piece 56a is pushed to the back side, but the inserted object can be gripped by the restoring force. That is, the notch 55 has a locking force. Further, it is preferable that the cut portion 54 is provided with two cuts 55. The notch 55a and the notch 55b are made from the side closer to the center 51c of the floor 51.

As the toilet mat cover according to the present invention that can be suitably used for the conventional pet toilet 50, the following points are added in addition to the configuration of the toilet mat cover 10. FIG. 4A shows the toilet mat cover 20. Like the toilet mat cover 10, the toilet mat cover 20 has a main body 21 having a plurality of through holes 12 formed and protrusions 14. The toilet mat cover 20 further has a vertical wall 22 around the main body 21 that faces downward from the surface of the main body 21. The vertical wall 22 is preferably provided on all four sides. The vertical wall 22 also functions to fix the absorbing sheet to be laid underneath.

Further, it is desirable that a notch 22h is formed in the vertical wall 22 at the center of each side of the main body 21. Here, the notch 22h is, for example, a gate-shaped notch. Further, it is desirable that at least the vertical wall 22 on the long side side of the main body 21 is formed. When the toilet mat covers 20 are used side by side as described later, they are used to connect the toilet mat covers 20 to each other.

Detachable leg members 23 are attached to the toilet mat cover 20 at at least two corners. Of course, it is more desirable if there are leg members 23 at all four corners. The leg member 23 is shown in FIGS. 4 (b) and 4 (c). FIG. 4 (b) is face up and FIG. 4 (c) is face down. The direction of gravity during use is indicated by an arrow G in the figure. The leg member 23 is a member having a leg protrusion 23c projecting vertically from a plate-shaped plane at an end of a plate-shaped member 23b provided with a step 23a. The leg protrusion 23c is composed of a base portion 23e projecting from a plate-like plane and an umbrella portion 23d having a diameter larger than that of the base portion 23e.

The toilet mat cover 20 is formed with a receiving hole 25 for detachably attaching the leg member 23. The receiving hole 25 may be a through hole formed in the vertical wall 22. The receiving hole 25 is formed in a shape that matches the cross section of the leg member 23 on the side where the leg protrusion 23c is not provided.

FIG. 5 shows a perspective view of the back surface of the toilet mat cover 20. A holding piece 26 is provided on the back surface of the main body 21. The holding piece 26 is for preventing the absorbing sheet from rising near the center of the toilet mat cover 20 and partially protruding from the through hole 12 so as to be caught by a pet's claw or the like and torn. Further, since the toilet mat cover 20 is provided with the vertical wall 22, the central portion is floating. Therefore, the holding piece 26 is also for supporting the pet even if it rides on it.

That is, the pressing piece 26 presses the absorbing sheet at a place other than the vertical wall 22 to support the pet. Therefore, the height 26t of the holding piece 26 (distance downward from the back surface of the main body 21) is substantially the same as the height 22t of the vertical wall 22. The place where the holding piece 26 is installed may be provided at least near the center of the toilet mat cover 20.

As described above, an example of using the pet toilet 1 according to the present invention, which is composed of the conventional pet toilet 50 and the toilet mat cover 20, will be described with reference to FIG. An absorption sheet 5 is placed on the conventional pet toilet 50. The four corners of the mounted absorption sheet 5 are locked by the notch 55a (see FIG. 3B). Since the conventional pet toilet 50 is made of silicone, the notch 54 is also flexible. The movable piece 56a formed by the crevice 56 is easily deformed. Therefore, the absorption sheet 5 can be easily locked by simply inserting the corner of the absorption sheet 5 into the notch 55a.

Next, the toilet mat cover 20 to which the leg members 23 are attached to the four corners is placed on the absorbent sheet 5, and the leg protrusions 23c of the leg members 23 are provided in the notches 55b outside the notches 55a in which the absorbent sheets 5 are locked. Plug it in. Also in this case, the movable piece 56a of the notch 55b is easily deformed, and the umbrella portion 23d of the leg protrusion 23c is locked by the notch 55b, resulting in a loosely fixed state. In this case, the floor 51 of the conventional pet toilet 50 corresponds to the tray portion of the pet toilet 1 according to the present invention, the cut portion 54 of the conventional pet toilet 50 and the leg member 23 of the toilet mat cover 20. Consists of the fixing means for the pet litter box 1 according to the present invention.

As described above, in the pet toilet 1 according to the present invention, the absorption sheet 5 is fixed by sandwiching the absorption sheet 5 between the conventional pet toilet 50 and the toilet mat cover 20. Further, even if the pet walks on the toilet mat cover 20, the absorbent sheet 5 will not be wrinkled and the position will not be displaced.

Further, since the treatment of urination and defecation has the same effect as described with respect to the toilet mat cover 10, it is easy to clean up and the toilet mat cover 20 can be washed at a long interval.

A pet litter box 2 (see FIG. 8) according to the present invention using a wide type of the conventional pet litter box 50 will be described with reference to FIG. 7. This conventional pet toilet 60 has the size of two absorbent sheets. That is, two absorbing sheets 5 can be used side by side. Further, an absorption sheet 6 having a size equivalent to two normal absorption sheets, which is called a wide type, may be used. In the conventional pet toilet 60, a notch 54 is formed not only at the four corners but also at the central portion of the long side. This is because the absorption sheet 6 does not shift.

In the pet toilet 2 according to the present invention using such a conventional pet toilet 60, two toilet mat covers 20 are used (see FIG. 7B). In this case, the connecting member 28 is attached to the notch 22h provided on the long side of the toilet mat cover 20, and the two toilet mat covers 20 are connected.

Here, the connecting member 28 is a substantially rectangular parallelepiped member in which two slits are formed, and the two toilet mat covers 20 are connected by inserting the notches 22h of the two toilet mat covers 20 into the slits.

In the state of the connected toilet mat cover 30, leg members 23 are attached to the four corners, and the absorption sheet 6 is sandwiched between the toilet mat cover 30 and the conventional pet toilet 60. FIG. 8 shows the configuration of the pet toilet 2 according to the present invention.

In this way, the toilet mat cover 20 can be connected to each other and used as the toilet mat cover 30. Therefore, it can be said that the toilet mat cover 20 is configured to be connectable. Here, a notch 22h is formed in the vertical wall 22 provided on the toilet mat cover 20, and two toilet mat sheets 20 are connected by a connecting member 28 that connects the notches 22h to each other. However, the form of connection is not limited to this, and may be connected by other methods.

Further, also in the case of the pet litter box 2 according to the present invention, the floor 51 of the conventional pet litter box 60 corresponds to a tray portion, and the notch portion 54 of the conventional pet litter box 60 and the leg member 23 of the toilet mat cover 20 It constitutes the fixing means of the pet litter box 2 according to the present invention.

FIG. 9 shows a pet litter box 3 according to the present invention using a conventional pet litter box 70. The conventional pet toilet 70 has a support plate 71 and a frame portion 72. The support plate 71 may have a flat surface on which the absorption sheet can be placed. The frame portion 72 is fixed to the support plate 71 to sandwich the absorbing sheet. Other shapes are not particularly limited.

The toilet mat cover 40 used in the conventional pet toilet 70 has an edge engaging portion that engages with the frame portion 72 or the support plate 71 at the edge. The form of the edge engaging portion is not particularly limited. For example, it may be a recess 42 that engages with the engaging protrusion 71a provided on the support plate 71, or may be a locking hole 44 through which the protruding portion 72a provided on the frame portion 72 penetrates. Further, a recess 46 may be provided on the side surface of the main body 41.

Further, the toilet mat cover 10 (see FIG. 1) itself can be used by sandwiching it between the support plate 71 and the frame portion 72 together with the absorbing sheet 5. The toilet mat cover 10 does not particularly engage with the support plate 71 or the frame portion 72, but the absorbent sheet 5 can be sufficiently fixed even if it is simply sandwiched between the support plate 71 and the frame portion 72. Even with such use, the effect of the toilet mat cover 10 on the excretion treatment can be similarly exerted.

In the pet litter box 3 according to the present invention, the tray portion corresponds to the support plate 71 of the conventional pet litter box 70, and the conventional pet litter box 70 and the edge engaging portion of the toilet mat cover 40 correspond to the fixing means. .. When the toilet mat cover 10 is used for the conventional pet toilet 70, the holding between the support plate 71 and the frame portion 72 corresponds to the fixing means.

As described above, the toilet mat cover according to the present invention and the pet toilet having the cover can easily perform the excretion process of pets.
