Description

[Detailed Description of the Invention] This invention relates to an improvement of the bottom box of a conventional pet case.

The bottom box of a conventional PET case is a four-walled box with a bottom plate, on which is placed a garbage receiving box that can be freely accessed and removed. It was installed by placing a security wire mesh on top of it. In addition, when attaching the wire mesh frame above the bottom box or the above-mentioned wire mesh to the four peripheral walls of the bottom box, the upper part of the four peripheral walls of the bottom box can be extended outward in steps to form a shelf. , placed on the shelf. Therefore, in the case of the bottom box of a conventional pet case, even though most of the water droplets and small food particles when small birds and small animals bathe can be collected by the garbage receptacle, the surrounding wall of the garbage receptacle and the peripheral wall of the bottom box are Water droplets and dirt got into the gaps between the two, and a bottom plate was needed to catch the water droplets and dirt. That is, since the peripheral wall of the garbage receiving box is located inside the inner peripheral wall of the bottom box, a gap is created between the peripheral wall of the garbage receiving box and the inner peripheral wall of the bottom box, and water droplets and fine garbage can fall through the gap. , or
When taking the bottom box in and out, the dirt that had accumulated in the gap would always fall to the bottom. Further, since the shelves on which the wire mesh and the wire mesh frame are placed are located outward from the inner circumferential wall of the bottom box, they do not serve to shield the gap therebetween.

By the way, in view of the current soaring prices of plastic molding materials, this invention allows the bottom box to be molded using half to 70% of the amount of material used for conventional bottom boxes. The purpose is to remove the bottom plate from the However, since the bottom plate of the bottom box plays the role described above, it is necessary to form something in place of the bottom plate in the bottom box, and when molding it from plastic, the mold is complicated and it is not cheap. Another disadvantage was that it could not be supplied in large quantities. Therefore, conventionally, there are bottom boxes made of metal plates without a bottom plate, or bottom boxes devised by the applicant in which the three walls of the back plate and both side plates are connected by hinges and formed into a flat shape are known. . but,
Since both of them have drawbacks such as durability and difficulty in use, the present invention has created a bottom box that has four walls exactly like the conventional bottom box but does not have a bottom plate.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the bottom box, and FIG. 2 is a sectional view taken along the line A--A in FIG. 1. 1 is the bottom box body, which is integrally molded from plastic. The bottom box main body 1 is open at the top and bottom and is formed into a square shape by rectangular four-walled plates. 2 and 2' indicate the side plates of the bottom box main body 1 among the four wall plates, 3 indicates the front plate, and 4 indicates the rear plate. These side plates 2, 2' are the front plate 3 and the back plate 4.
The vertical width is longer than that, and there are side plates 2, 2' at the bottom of both sides.
Leg portions 5, 6, 7, and 8 are formed by extending the . Further, leg portions 6' and 8' formed by extending the lower ends downward are connected to both lower ends of the back plate 4.
However, these leg portions 6' and 8' also serve as a stop plate to prevent the garbage receiving box described below from being inserted and removed to the rear of the rear surface. Further, on the inner wall surface 1o of the four wall plates of the bottom box body 1, a series of mounting shelves 9 for depositing wire mesh are provided, each of which protrudes inward. However, in this case, since the vertical widths of both side plates 2 and 2' and the front and rear plates 3 and 4 are different, the front and rear plates 3 and 4 are connected to the lower edge of the front and rear plates 3 and 4. It is formed as follows. In addition, on the inner wall surface 10 of both side plates 2, 2' below the placement plate 9, there are a plurality of flat plate-shaped protrusions 12, 12 on which a collar 13 of a garbage receiving box 11 described below is slidably placed. It is formed to protrude.

The protrusions 12, 12 are divided into a front protrusion 12a and a rear protrusion 12b, and have different configurations. The front protruding part 12a located close to the front plate 3 is formed with its tip 15 inclined obliquely upward, and its rear part 16 is parallel to the above-mentioned storage shelf 9 from the rear end edge of the tip 15. The tip 1
They are formed to extend rearward at intervals longer than 5. Further, in the embodiment, the rear protrusion 12b is formed to be inclined diagonally upward like the tip 15 of the front protrusion 12a;
They may be formed flat, and the number of formations is not limited.

It is also assumed that the inward protrusion width of the protrusions 12 is smaller than or equal to the width of the upper loading shelf 9. Reference numeral 11 denotes a garbage receiving box of the bottom box body 1, and a collar 13 is formed in a continuous manner at the upper end of the peripheral wall of the garbage receiving box 11. This garbage receiving box 11 is the bottom box body 1.
To insert and attach the garbage receiving box 11 to the bottom box body 1, insert the garbage receiving box 11 into the bottom box body 1 from the front opening 14 with the garbage receiving box 11 in the front direction B, and then insert the garbage receiving box 11 into the bottom box body 1 through the front opening 14. The garbage receiving box 11 is placed on the tip 15 of the protruding portion 12 and slid along the inclined surface of the full end portion 15 to move the garbage receiving box 11 rearward and attach it. In this case, the rear part 16 of the front protrusion 12a and the upper end of the rear protrusion 12b are both at the same height,
This protrusion 12 supports the collar 13 of the garbage receiving box 11, and the garbage receiving box 11 is placed thereon.

As described above, the present invention forms the bottom box body 1 consisting of the front plate 3, the back plate 4, and the side plates 2, 2', and the inner wall surfaces 10 of the front plate 3, the back plate 4, and the side plates 2, 2'. A series of mounting shelves 9 are formed that project inward.

Therefore, when small animals or birds bathe on the wire mesh placed on the above-mentioned shelf 9, water splashes and scattered food particles are blocked by the inner wall surface 10 of the above-mentioned front plate 3, etc. Does not jump out from the box,
It will not stain the area around the pet case. In particular, compared to conventional pet cases that do not have a bottom plate in the bottom box and do not have a front plate to take out and put in the garbage receiving box, the floor near the entrance and exit of the garbage receiving box gets dirty. is completely absent. In addition, water droplets and food particles blocked by the inner wall surface 10 of the front panel 3, etc., can be removed by placing a wire net mounting shelf 9 on the inner peripheral surface of the front panel 3, side panels 2, 2', and rear panel 4. Therefore, when the garbage receiving box 11 is inserted onto the protrusions 12, 12 directly below the loading shelf 9, the garbage receiving box 1 located below along the upper surface of the loading shelf 9 is inserted.
It will fall to the bottom of the trash receptacle 11.
can reliably catch water droplets and fine dust. Therefore, conventionally, both side plates 2 of the bottom box body 1,
Water droplets and fine dust do not enter into the gaps between 2' and the back plate 4 and the peripheral wall of the dust receiving box 11.

Further, the bottom box of the present invention is composed of four wall plates 2, 2', 3, and 4, and the four wall plates 2, 2',
Since a series of mounting shelves 9 are formed on the inner wall surfaces 10 of the four walls 2, 2', 3, and 4 to protrude inward in a series including the front panel 3, the mounting shelves 9 are provided with ribs on the four wall panels 2, 2', 3, and 4. It plays the same role as forming a shell, is strong against twisting and distortion, and can firmly hold a large amount of weight, so it can be used for large pet cases such as mynah birds.

Further, in the present invention, the protrusions 12, 12 that protrude inwardly from the inner wall surfaces 10 of the side plates 2, 2' are formed in a flat plate shape, and the front protrusion 12a located near the front plate 3 has its tip 15. is formed to be inclined diagonally upward, and the rear portion 16 extends rearward from the rear end edge of the tip portion 15 in the horizontal direction with respect to the storage shelf 9 at a distance longer than the length of the tip portion 15. is forming.

Therefore, when the flange 13 of the garbage receiving box 11 is placed on the tip 15 and slid, it can be slid extremely smoothly along the inclined surface of the tip 15 due to the flat plate shape, and the flange 13 can be slid very smoothly along the slope of the tip 15. The collar 13 of the garbage receiving box 11 can be placed very stably and reliably on the rear portion 16 having a long horizontal distance from the container 9.

In addition, in the present invention, the part on which the garbage receiving box 11 is slidably placed is divided into a plurality of protruding parts 12, 12, so that the bottom box main body 1 is divided into four wall plates 2, 2', 3 and 4, and a protruding part is formed directly under the shelf 9, the bottom box body 1 can be formed into a slide core or a mold without using a complicated and expensive mold such as a split mold. The bottom box body 1 can be integrally molded using an injection mold using finger pins, and the bottom boxes of PET cases can be manufactured in large quantities at low cost.

Based on the above, the bottom box of the present invention is an epoch-making bottom box that eliminates the negative effects of removing the bottom plate from the bottom box and reduces the amount of molding material used by the bottom plate, which is compatible with the current economic situation. It is inexpensive and can be supplied to the market in large quantities using plastics.
