  The toilet for pets provided with the conventional mesh-shaped cocoon pups as described in Patent Documents 1 and 2 is the back side of all the excretion fluid such as urine excreted on the surface of the cocoon pupae (the surface facing the pet performing the excretion operation). In some cases, a part of the excretory fluid may remain on the surface of the pupae without being able to shift to the side. In particular, the intersection where the wire materials constituting the cocoon child cross each other tends to cause the excreted liquid to remain as droplets, which is the main cause of the remaining liquid on the surface of the cocoon child. The surface of the puppet often forms the outer surface of the toilet for pets, and is a relatively easily noticeable part. The excreted liquid remaining on the surface of the pupae can cause a bad odor and is inconvenient for the pet owner. There is also a possibility of giving a pleasant feeling and further transferring to a pet walking on the surface, and the pet walking around the room may contaminate the room. Note that the techniques disclosed in Patent Documents 1 and 2 do not take into account the suppression of liquid residue on the surface of the eggplant.

  Therefore, the subject of this invention is providing the toilet for pets which can prevent the surface liquid residue of excretion liquid effectively.

  The present invention is a pet toilet comprising a kite puppet, a tray disposed below the kite puppet, and an absorbent sheet accommodated in the tray, wherein the kite puppet includes a plurality of first tubs extending in one direction. One wire rod and a plurality of second wire rods extending in a direction crossing the one direction, and the plurality of first wire rods and the plurality of second wire rods are parallel to each other with an interval therebetween. At the intersection where the first wire and the second wire intersect, one of the two wires protrudes upward from the portion not intersecting the other to form a protrusion, and the other By providing a pet toilet that passes under the protruding portion, and the absorbent sheet is in contact with the other wire rod that passes under the protruding portion below the protruding portion. The above-mentioned problem is solved.

  The toilet for pets of the present invention can effectively prevent the remaining surface liquid of excretory liquid.

It is sectional drawing which shows typically the II-II line cross section (thickness direction cross section of a scissors) of (a).

  Hereinafter, the pet toilet according to the present invention will be described based on a preferred embodiment thereof with reference to the drawings. 1 to 3, the pet toilet 1 of the present embodiment is arranged on the bottom wall 31, the side wall 32 connected to the bottom wall 31, and the bottom wall 31. The tray 3 which has the opening part 33 which opposes, and the absorptive sheet 4 accommodated in the tray 3 are provided.

  The kite child 2 constitutes a pet scaffold that performs excretion in the pet toilet 1, and is substantially flat and has a substantially rectangular shape in plan view, and is close to a pet when the toilet is used as shown in FIG. The first surface 21 located on the side (the surface of the cocoon child 2) and the second surface 22 located on the side opposite to the first surface 21 and located on the side far from the pet when using the toilet (the back surface of the cocoon child 2) have. Normally, granular materials such as toilet sand are not loaded on the first surface 21, and the pet rides directly on the first surface 21 and excretes urine and the like when using the toilet. Therefore, when the toilet is used, the first surface 21 first receives excretory fluid. In this specification, the side closer to the pet when using the toilet is also referred to as “upward” and the side farther from the pet is also referred to as “lower”.

  As shown in FIG. 1 to FIG. 3, the spider 2 includes a frame body 23 that forms a peripheral portion (outline) of the spider child 2, and a region (excretion region) surrounded by the frame body 23. The frame body 23 has a shape obtained by hollowing out an inner portion of a substantially rectangular shape in plan view, excluding its peripheral portion, from a substantially rectangular plate shape in plan view. A portion corresponding to the portion is the excretion region.

  4 and 5 show a part of the excretion area of the pupa 2 in an enlarged manner. The scissors 2 are a plurality of linear first wires 24 extending in one direction X in the surface direction (horizontal direction) of the first surface 21 and a plurality of linear shapes extending in a direction Y intersecting (orthogonal) with the one direction X. And the second wire rod 25. The direction X coincides with the longitudinal direction of the cage 2 (pet toilet 1), and the direction Y coincides with the width direction of the cage 2 (pet toilet 1) orthogonal to the longitudinal direction X. The plurality of first wire rods 24 and the plurality of second wire rods 25 are respectively arranged in parallel at intervals. Since the excretion region is configured by arranging the wires 24 and 25 in a lattice shape in this way, the excretion region is surrounded by both the wires 24 and 25 and has a rectangular shape in plan view. Many liquid holes 26 are formed. The liquid permeable hole 26 penetrates the cocoon child 2 in the thickness direction, and excreted liquid such as urine excreted on the first surface 21 side moves to the second surface 22 side via the liquid permeable hole 26. To do. An intersection 27 where the first wire 24 and the second wire 25 intersect is formed around (four corners) around the quadrangular liquid-permeable hole 26.

  As shown in FIGS. 4 and 5, each of the first wire 24 and the second wire 25 is a metal wire (for example, made of stainless steel) having a circular cross section, and a bent part of which is bent or curved. Is a wire rod with a curved portion. In each first wire 24, the plurality of curved portions 24 </ b> P are constant in the length direction (direction X) of the first wire 24 by matching their bending (curving) directions (the protruding direction of the top of the curved portion 24 </ b> P). The two curved portions 24P and 24P adjacent to each other are provided at intervals, and a straight portion 24Q having no curved portion is formed. Moreover, in each 2nd wire 25, the some bending part 25P makes those bending (curving) directions (projection direction of the top part of the bending part 25P) correspond, and the length direction (direction Y) of the 2nd wire 25 Are provided at regular intervals, and between the two adjacent curved portions 25P, 25P is a straight portion 25Q having no curved portion.

More specifically, the convex portion 45 of the absorbent sheet 4 is a portion in which the absorbent sheet 4 is supported from below by the flange portion 35 of the tray 3, and the surface 4 a side thereof is directed upward (the edge 2). It protrudes. The plurality of convex portions 45 respectively correspond to the flange portion 35 and continuously extend over the entire length in the width direction Y of the absorbent sheet 4, and the protruding portion (curved portion 24 </ b> P) at the intersection 27 of the flange 2. Or it is located below 25P) and is in contact with a wire rod (straight line portion 25Q or 24Q) passing below the protruding portion. Further, between the two adjacent convex portions 45, 45 of the absorbent sheet 4 corresponds to the groove portion 36 of the tray 3 and is not supported from the lower side. Therefore, as shown in FIG. The surface 4a side is a recess 46. The absorbent sheet 4 is not in contact with the scissors 2 at the recess 46. Thus, the absorbent sheet 4 accommodated in the tray 3 has a plurality of convex portions 45 and a plurality of concave portions 46 extending across the entire length in the width direction Y of the absorbent sheet 4 on the surface 4a side. By alternately arranging the absorbent sheets 4 in the longitudinal direction X orthogonal to the direction Y, irregularities are formed, and the convex portions 45 constituting the irregularities are in contact with the scissors 2.

The dimensions and the like of each constituent member in the tray 3 are not particularly limited, but can be set as follows.
The protrusion height t2 (see FIG. 2) of the heel part 35 is such that the liquid is transferred from the cocoon child 2 to the absorbent sheet 4, and the absorbent sheet is on the uneven surface 31a when a large amount of urine is absorbed. From the viewpoint of stable installation, the thickness is preferably 1 to 50 mm, more preferably 5 to 30 mm.
The width w1 (see FIG. 2) of the collar portion 35 is preferably 3 to 30 mm, more preferably 5 to 25 mm, from the viewpoint of stable installation of the absorbent sheet 4. From the same viewpoint, the width of the groove portion 36 (interval between adjacent flange portions 35, 35) w2 (see FIG. 2) is preferably 0 to 30 mm, and more preferably 5 to 15 mm.
The size of the tray 3 is not particularly limited. For example, in the upper end portion 32 a, the tray 3 has a long side of 25 to 210 cm, a short side of 15 to 160 cm, and a square shape of 15 to 210 cm when the flat side is rectangular, and the side wall 32 has a height of 2 ~ 15 cm. In addition, the dimension of each part of the tray 3 shown here is an internal dimension (dimension inside the tray 3).

  The material for forming the tray 3 is not particularly limited as long as it has corrosion resistance. The tray 3 is integrally formed of a general-purpose synthetic resin such as polypropylene, polyethylene, polyethylene terephthalate, vinyl chloride, acrylonitrile-butadiene-styrene copolymer (ABS) because it is lightweight, easy to handle and has good moldability. The ones made are preferred. In addition, a resin or the like whose surface is subjected to water-repellent processing or antibacterial processing is also preferably used as a material for forming the tray 3.

  As the absorbent sheet 4, those capable of absorbing and holding excretory fluids such as urine in the technical field can be used without particular limitation. The absorbent sheet 4 is preferably formed from a raw material containing one or more components such as pulp fiber, clay mineral material, and polymer absorbent material into a plate shape (sheet shape). The shape and size of the plate-like absorbent sheet 4 in plan view can be substantially the same as the shape (rectangular shape) and size of the bottom wall 31 of the tray 3 in plan view. The thickness of the plate-like absorbent sheet 4 is preferably 0.1 to 20 mm, particularly 1 to 15 mm, from the viewpoints of installation properties and ease of storage.

  The pet toilet 1 of the present embodiment is in a state where the cage 2 is fitted (arranged) on the tray 3 so as to cover the opening 33 (see FIG. 3) of the tray 3 as shown in FIGS. use. The absorbent sheet 4 is disposed on the inner surface (uneven surface) 31 a of the bottom wall 31 of the tray 3. On the first surface 21 of the kite 2, granular materials such as toilet sand are usually not loaded. When excretory fluid such as urine is excreted toward the first surface 21 in a state where the pet is on the first surface 21 of the spider child 2, the excretion fluid passes through the persimmon child 2 in the thickness direction. It moves to the second surface 22 side through the liquid hole 26 and is absorbed and held by the absorbent sheet 4 in contact with the second surface 22. The pet toilet 1 of this embodiment is suitable as a toilet for animals such as dogs, cats, rabbits, and hamsters, and is particularly suitable as a toilet for dogs.

  According to the pet toilet 1 of the present embodiment, the excretion is performed on the first surface 21 of the excretion region (region surrounded by the frame body 23) of the salmon child 2, which is a surface that first receives excretion fluid of the pet. Since the intersection 27 of the wire rods 24 and 25 constituting the region is configured to include a protruding portion (curved portion 24P or 25P) in which one of the wire rods protrudes upward from the peripheral portion, It is difficult to remain on the outer surface, and quickly moves to the second surface 22 side along the outer surface. In addition, the other wire constituting the intersection point 27 passes through the lower part of the projecting portion, and the other wire and the absorbent sheet 4 (convex part 45) located below the contact are in contact with each other. The excretory fluid transferred from the first surface 21 side to the second surface 22 side via the protruding portion is quickly absorbed and held by the absorbent sheet 4. Therefore, the toilet 1 for pets of the present invention hardly causes liquid residue on the first surface 21 and is excellent in hygiene. Inconvenience due to such liquid residue (bad odor, discomfort to the pet owner, The occurrence of soiling etc.) can be effectively prevented.

  Further, in the present embodiment, a plurality of convex portions 45 and a plurality of concave portions 46 extending over the entire length in the width direction Y of the absorbent sheet 4 on the surface 4a side (the surface facing the scissors 2) of the absorbent sheet 4. Are alternately arranged over the longitudinal direction X of the absorbent sheet 4 perpendicular to the width direction Y, the surface 4a has irregularities, and the convex portions 45 constituting the irregularities are the scissors 2 Since the concave portion 46 that makes up the concave and convex portions is not in contact with the spider 2, the excretory fluid that has migrated into the absorbent sheet 4 through the convex portion 45 is the width of the absorbent sheet 4 at the concave portion 36 in the vicinity thereof. It is diffused in the direction Y, whereby the entire absorbent sheet 4 can be used more efficiently.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, the shape of the scissors 2, the tray 3, and the absorbent sheet 4 in a plan view is not limited to the rectangular shape as in the above embodiment, and may be a circle, an ellipse, or the like. However, in consideration of the habit related to the excretion of the pet, it is preferable that one direction has a relatively long shape in plan view.

  Moreover, in the said embodiment, the surface (bottom surface) in which the unevenness | corrugation is formed in the tray 3 from the viewpoint of providing an unevenness | corrugation to the surface (opposite surface facing the scissors 2) 4a side of the absorbent sheet 4 in the tray 3. For this purpose, the flange portion 35 and the groove portion 36 are formed on the inner surface 31a of the bottom wall 31 of the tray 3 on which the absorbent sheet 4 is placed to provide unevenness. However, the inner surface 31a is a flat surface without irregularities, and instead, irregularities are formed between the flat inner surface 31a and the absorbent sheet 4 on the surface facing the absorbent sheet 4. Another member (uneven sheet) may be interposed. Moreover, you may use the sheet | seat with which uneven | corrugated shape was provided to the surface 4a as the absorptive sheet 4, and what provided the uneven | corrugated shape to the whole sheet (for example, a bellows-shaped absorbent sheet).

  Moreover, in the said embodiment, the 1st wire 24 and the 2nd wire 25 are metal, such as stainless steel, and the said excretion area | region (area | region enclosed by the frame 23) is the textile fabric which consists of these metal wires. However, the first wire 24 and the second wire 25 may be made of a resin such as polyethylene, polypropylene, polyethylene terephthalate, and the excretion region may be a resin molded body made of the resin wire. In that case, at the intersection 27 where the first wire rod 24 and the second wire rod 25 made of resin intersect, one (the projecting portion) and the other (the straight portion) of the two wire rods 24 and 25 are integrally formed.
