JP4510684B2 - Toilet for pet animals - Google Patents

Description

  The present invention relates to a pet animal excrement receptacle generally called a pet toilet, and relates to a toilet used by pet animals such as dogs and cats (pets).

  Normally, it is made of a synthetic resin molded product, and includes a tray-like main body having an impermeable bottom plate, and a cover frame that is fitted and locked to the peripheral portion of the main body, and has a water-absorbing waste receiving sheet ( A toilet for pet animals having a structure in which the periphery of the water absorbent sheet is sandwiched between the main body and the cover frame by placing the cover on the bottom plate of the main body and fitting the cover frame on the main body is known. It is.

  With the increase in indoor pets (especially dogs), there is a growing demand for this kind of pet toilet installed indoors. Conventional pet toilets have a relatively easy water absorption sheet when pets enter and exit the toilet. Therefore, the use efficiency of the water-absorbing sheet is reduced, frequent replacement of the sheet is necessary, feces and urine excreted from pets adhere to the main body and become contaminated, and much effort is required for cleaning. There is a problem that it takes.

  From the above, the amount of water-absorbing sheet used is increased, the owner's economic burden is increased, and the increase in the amount of sheet used increases the generation of harmful substances such as carbon dioxide accompanying the incineration.

  On the other hand, a pet toilet having a structure for covering a mesh plate made of a synthetic resin provided with a large number of fine holes through which a pet's feet do not pass is provided on a water absorbent sheet. With this structure, the problem of movement of the water-absorbing sheet does not occur, but urine accumulates on the mesh board due to surface tension, and when the pet moves on the mesh board, the urine sticks to the pet's sole and becomes dirty, If the pet leaves the toilet as it is, the surrounding area becomes dirty, which is unsanitary. Further, since indoor dogs are usually trained to urinate on a paper water-absorbing sheet, there is also a problem that urination must be repeated again in order to urinate on a mesh screen made of synthetic resin.

In addition, as a structure that prevents the movement of the water absorbent sheet, a structure that increases friction by laying a net covered with a soft resin under the water absorbent sheet, or a protrusion or the like between the main body and the cover frame is provided, and the periphery of the sheet A structure that strengthens the fixing of parts has been proposed.

  Such an improved pet toilet can substantially prevent the water-absorbing sheet from moving on the main body, and thus solves the above problems to some extent. However, when the pet scratches the water absorbing sheet with the forelimbs, the sheet cannot be prevented from moving, and the paper constituting the water absorbing sheet can be played by biting and playing with the sheet pulled out between the main body and the cover frame. And water-absorbing polymers are scattered around, increasing the owner's cleaning effort. Furthermore, there are various problems such as cases in which pets chew and play with the water-absorbing sheet that has been lifted off and are accidentally swallowed, resulting in diseases such as enteritis and bowel obstruction, and these problems have not been solved.

  In view of the problem of such a conventional pet toilet, the present invention not only prevents the movement of the water absorbent sheet on the main body, but also prevents the sheet from shifting or floating even if the pet scratches the water absorbent sheet with the forelimbs. An object of the present invention is to obtain a pet toilet that can firmly fix a water-absorbing sheet and can prevent filth from adhering to the pet's feet.

  In the present invention, on the surface of the main body facing the back side of the sheet, a groove consisting of several to dozens of vertical and horizontal is provided, a water absorbent sheet is laid thereon, and steel or vinyl chloride is used in accordance with the position of the groove. The above-mentioned problem is solved by covering the constructed wire rod and pressing the water-absorbing sheet into the groove to firmly fix the water-absorbing sheet to the main body.

That is, the toilet for pet animals according to the invention of claim 1 of the present application is a toilet for pet animals provided with a main body 1 having an impermeable bottom plate and a cover frame 17 attached to the main body. a vertical lateral grooves 6 and 7 are arranged, and a holding grating 13 having a wire 15, 16 which are arranged vertically and horizontally to fit to be inserted from above into the groove in the arrangement of the grooves, the pressing The wire rods 15 and 16 of the lattice have a structure in which a waste receiving sheet 19 placed on the bottom plate of the main body 1 is pushed into the groove and fixed.

  A pet animal toilet according to the invention of claim 2 of the present application is a pet animal toilet having the above-described structure, wherein the main body 1 locks the peripheral frame 14 or the wires 15 and 16 of the presser grid 13. The holding grid 13 is fixed to the filth receiving sheet 19 by the wire rods 15 and 16 being immersed in the grooves 6 and 7 while being locked by the locking member 12. Is.

  The toilet for pet animals according to the invention of claim 3 of the present application is the toilet for pet animals having the above structure in which the main body 1 is provided with a locking tool 18 for locking the cover frame 17. The wire rods 15 and 16 are inserted into the grooves 6 and 7 and fixed to the filth-receiving sheet 19 while being sandwiched between the cover frame 17 and the cover frame 17 locked thereto. It is.

  Further, the pet animal toilet according to the invention of claim 4 of the present application is the pet animal toilet having the above structure in which the main body 1 is provided with a locking tool 18 for locking the cover frame 17. It is attached to the cover frame 17.

  In the conventional pet toilet, the body and the cover frame that fixes the peripheral part of the water absorbent sheet were pressed to suppress the movement of the sheet, but the pressing part was limited to the sheet peripheral part, so the fixing was insufficient, Since the sheet easily moves and the sheet itself is made of paper pulp, the pet is often easily torn or moved when the pet is scratched with a nail or the pet bites.

  In the toilet of the present invention, the water absorbent sheet is pressed in a state of being pushed into the groove by several to ten or more grooves on the surface of the main body and wires arranged in accordance therewith, and the entire water absorbent sheet is firmly fixed. can do. As a result, various problems in the conventional toilet described above are solved, and the effect of suppressing the labor and economic burden of the owner in pet defecation and urination indoor breeding is tremendous. Further, the use efficiency of the sheet main body can be increased, the generation of harmful substances such as carbon dioxide accompanying the incineration of the sheet can be reduced, and it can be imparted to maintaining the health of the pet itself.

  Hereinafter, an example of a preferred embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of the assembled pet toilet, FIG. 2 is a plan view of the main body, FIG. 3 is a cross-sectional view of section A in FIG. 2, FIG. 4 is a plan view of the presser grid, and FIG.

  The main body 1 is a flat rectangular injection-molded product, and is provided with a peripheral flange 2 having a cross-shaped reverse letter shape along the outer periphery thereof, and is provided with a peripheral groove 3 adjacent to the inner periphery of the peripheral flange and surrounded by the peripheral groove. The flat portion is a flat bottom plate 4 that is approximately half the height of the circumference. Reinforcing ribs 5 are integrally formed on the back surface of the bottom plate 4, and grooves 6 and 7 having U-shaped or V-shaped cross sections are formed on the top surface of the bottom plate 4 in the vertical and horizontal directions. Finger insertion portions 8 having a wider groove width are provided on the outer side of the circumferential groove 3 at four locations in the longitudinal direction and two locations in the width direction. Further, a cover latching portion 9 is formed in the center portion in the longitudinal direction of the circumferential collar 2 by notching the outer peripheral skirt portion.

  A locking metal fitting 12 formed by bending a spring plate through two slits 10 and 11 provided in the groove bottom is attached to a portion of the circumferential groove 3 provided with the finger insertion portion 8 in the longitudinal direction (FIG. 3). reference). This locking metal fitting is provided with a pressing surface 12a for pressing the upper end with a finger and bending it outward, and a step portion 12b for locking a peripheral frame 14 of a pressing grid 13 to be described later is formed immediately below the pressing surface. Yes. The lower part of the locking metal fitting 12 is bent in an upward U-shape, and the slight bending provided in the bent portion is fitted to the edges of the slits 10 and 11 to prevent the locking metal fitting 12 from falling off. Yes.

  As shown in FIG. 4, the presser grid 13 is a grid-like structure in which a peripheral frame 14 is fixed around vertical and horizontal wires 15 and 16 that match the distance and number of the vertical and horizontal grooves 6 and 7 provided on the bottom plate 4 of the main body. It is a member. The wire rods 15 and 16 and the peripheral frame 14 are, for example, piano wires, which are formed by welding their intersections and are entirely coated with resin or paint. One of the vertical and horizontal wires 15 and 16 is below the other at the intersection. For example, when the longitudinal wire 15 is positioned below the width wire 16, the depth of the longitudinal groove 6 provided on the bottom plate 4 of the main body is made deeper than the depth of the width groove 7. The peripheral frame 14 is preferably fixed on the vertical and horizontal wires 15 and 16. In this case, the end of the wire positioned below is slightly bent upward so that the end is flush with the end of the wire positioned above.

  The cover frame 17 is a frame-like member fitted so as to cover the upper part of the peripheral flange 2 and the peripheral groove 3 of the main body, and is a synthetic resin injection-molded product. In the example of FIG. 1, the inwardly extending ridge 18 provided at the center of the peripheral edge in the longitudinal direction is engaged with the upper edge of the cover locking portion 9 provided in the main body by the elasticity of the cover frame 17 itself. It is fixed to.

  In the pet toilet having the above structure, a commercially available water-absorbing sheet 19 for receiving waste is placed on the upper surface of the bottom plate 4, and the peripheral frame 14 of the presser grid 13 is placed so that the wires 15 and 16 are fitted into the grooves 6 and 7 from above. It fixes in the state hooked on the step part 12b of the latching metal fitting 12. As shown in FIG. At this time, the wire rods 15 and 16 of the holding grid are bent into a U-shape by absorbing the water-absorbing sheet 19 directly below them into the grooves 6 and 7, and the water-absorbing sheets in which the wires 15 and 16 themselves are also bent into a U-shape. It will be buried or semi-submerged in the groove. As described above, in a state where the wire rods 15 and 16 push the water absorbent sheet 19 into the grooves 6 and 7, the wire rods 15 and 16 may be bent upward due to the pushing reaction force. In that case, as shown in FIG. 5 (b), the presser grid 13 is bent in a downwardly convex state in advance, and the water absorbing sheet 19 is made into the groove 6, by the repulsive force when trying to return this bending to the horizontal. 7 may be pushed into the inside.

  After fixing the water absorbent sheet 19 with the presser grid 13 in this way, the cover frame 17 is attached to the peripheral edge of the main body 1 for use. In use, since the entire surface of the water absorbent sheet 19 is fixed by the wires 15 and 16, there is no possibility that the water absorbent sheet 19 is displaced or lifted up even if the pet scratches the foot. In addition, since the wires 15 and 16 have a rough lattice shape, the wires themselves are also pushed into the grooves formed by bending the upper surface of the water-absorbing sheet 19, so that urine does not accumulate on the wires 15 and 16 due to surface tension. The urine does not adhere to the feet of the pet walking on the water absorbing sheet 19.

  When the soiled water absorbing sheet is replaced, the cover frame 17 is removed, and the presser surface 12a of the lock fitting 12 is pushed to bend the lock fitting 12 outward, thereby releasing the lock of the press lattice 13. When the pre-deflection as shown in FIG. 5B is given to the presser grid 13, the longitudinal peripheral edge of the presser grid 13 (the widthwise bend as shown in FIG. 5B) is released. Therefore, the presser grid 13 may be removed, and the water absorbent sheet 19 may be removed and replaced.

  Since the wire rods 15 and 16 of the presser grid are located on the water absorbent sheet 19, it is inevitable that the filth excreted on the water absorbent sheet 19 adheres to the wire rods 15 and 16, but the wire rods 15 and 16 are spaced apart from each other. Since it is a thin member arranged, dirt adheres little, and even if it is reused as it is, it will be immersed in a groove formed by pushing the upper surface of a new water absorbent sheet, so that the pet's feet walking on it will not be soiled. Of course, when the presser grid 13 is removed, the filth attached to the wires 15 and 16 can be easily cleaned by washing with water or rubbing.

  The above embodiment is a structure in which the presser grid 13 is locked by the locking metal fitting 12 attached to the main body 1, but it may be integrated with the cover frame 17 and attached and detached together with the cover frame 17. Further, when the peripheral edge of the presser grid 13 placed on the water absorbing sheet 19 is fixed to the main body 1 without providing the locking metal fitting 12, it is pushed down by the cover frame and the wires 15, 16 May be pushed into the grooves 6 and 7. In this case, it is desirable that the locking structure between the cover frame 17 and the main body 1 is a structure that is firmly fixed using, for example, a clasp.

  As shown in the above embodiment, the structure in which the presser grid 13 is separated from the cover frame 17 allows only the presser grid 13 to be replaced with a new one when the presser grid 13 is damaged. There is an advantage.
