Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a metal plate door for a pet house such as a dog kennel, and particularly to a door with a lattice.

[Conventional technology]

Conventionally, the metal plate door has an opening formed in the door body, and a plurality of pipes or round bars are fixed to the opening as a grid material by spot welding or caulking at predetermined intervals, or the door body is fixed to the opening by spot welding or caulking. A plurality of lattice surface parts were formed by punching in the middle part of the board.

[The problem that the idea aims to solve]

However, in the former case, the door body and the lattice material are manufactured separately and then welded, etc.
This method is extremely time-consuming and unsuitable for mass production, resulting in high production costs and the occurrence of defective products due to poor welding. Also, in the latter case,
It was undeniable that the lattice material lacked strength and gave a feeling of being weightless and cheap.

The present invention has been made with the above-mentioned considerations in mind, and its purpose is to provide a metal plate door for a pet house that is easy to manufacture, durable, and safe for pets.

[Means to solve the problem]

In order to achieve the above-mentioned object, the metal plate door of the pet house according to the present invention includes a face plate part that connects between the top and bottom of the door body, and a bent plate part that is connected by bending both left and right ends of this face plate part. It is characterized by having a lattice material formed into a cylindrical shape, and horizontal bars that cover the openings at both the upper and lower ends of the lattice material.

[Effect]

According to the above configuration, the molding process can be easily performed and the material can be used effectively. The lattice material is cylindrical, and the openings at both the upper and lower ends of the lattice material are covered with horizontal bars, so even though the lattice material is formed by bending a metal plate,
The door is safe for pets because it does not catch hands, feet, or body hair, and the horizontal bar acts as a reinforcing material for the door body, so that the door is strong and beautiful as a whole.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows an example of a pet house made of steel plates for keeping pets such as dogs. The peripheral wall 2 is formed by a front side wall 4, a rear side wall 5, and left and right side walls 6 and 7. The rear wall 5 and the left and right side walls 6, 7 are all made of a single piece of painted steel plate, but the front wall 4 is made of, for example, the left and right side walls 6, 7.
It is located between pillar parts 6' and 7' formed into a hollow shape by bending the front end of the front plate 7, and has a front plate 8 having a plurality of punching holes 8a, and one end of which is hinged to the pillar part 7'. It is formed from a door 9 which is attached and is formed in an opening type that can swing open and close around a vertical axis.

FIG. 2 shows the door 9 in detail, 11a
11d is an outer edge portion formed by bending the four circumferences of the door body 10. Reference numeral 12 denotes a lattice material formed in the middle part of the door body 10 except for the upper and lower parts of the door body 10, which is formed into a cylindrical shape by punching, bending, or winding the door body 10, for example. The cross-sectional shape is trapezoidal in the illustrated one. 13 are outer edge portions 11a, 1 at both ends of the lattice material 12;
Bent parts 11c', 11 formed on the inner side of 1b
d' and at both upper and lower ends of the lattice material 12
The horizontal crossbar is fixed by welding or the like so as to cover the opening 12a, and it improves the appearance by preventing the opening 12a from being exposed, and serves as a reinforcing material for the door body 10 while ensuring the safety of dogs and humans. It is something to do. 1
4 is a hole for attaching a hinge, and 15 is a space formed by the lattice material 12.

Next, the manufacturing process of the door 9 will be explained based on FIG. 3. Figure A is a plan view showing the steel plate plate 21 before forming the lattice material 12 of the door body 10, Figure B is a sectional view taken along the line X-X of Figure A, and Figures H to H are in the folded state. FIG.

First, the punched portion 16 having a predetermined size and a predetermined shape is removed from the plate-shaped body 21 by punching, and the door body 1 is removed.
A face plate part 17 that extends between the upper and lower parts of 0, and this face plate part 1
A bending plate portion 18 is provided by bending both left and right ends of 7.
are formed on both sides of the face plate portion 17 (see A in the figure).
Next, the end portion 18' of the bent plate portion 18 is bent at a slight angle α (see FIG. 3C). Then, it is bent at the boundary between the bent plate part 18 and the face plate part 17 (see D of the same figure). Furthermore, when winding is performed so that the ends 18' of the bent plate part 18 butt each other,
A lattice material 12 having a trapezoidal cross-sectional shape is formed (see E in the figure).

In addition, in the above-mentioned bending and winding processes,
Press processing or bender processing is performed,
Press processing is preferable. Further, the outer edge portions 11a to 11d of the door body 10 may be bent appropriately to form a predetermined shape.

In the above-mentioned embodiment, the lattice material 12 is connected to the face plate part 17 which is continuous between the upper and lower parts of the door body 10 and this face plate part 1.
A bent plate portion 18 that is connected by bending both left and right ends of 7.
However, as shown in FIG. 4, the cross-sectional shape of the lattice material 12 can be, for example, semicircular (see A in the same figure) or triangular (see B in the same figure). ) or rectangular (see figure C).

In the above embodiment, the door body 10
Although the substantially I-shaped punched portion 16 is removed from the door body 10, the present invention is not limited to this. For example, as shown in FIG. 5, a cut groove 20 for bending the door body 10 is removed. may be formed.

Further, in the above-mentioned embodiment, the outer edges 11a to 11d are provided around the four circumferences of the door body 10, but a decorative edge made of, for example, synthetic resin is attached to the door body 10 on which only the lattice material 12 is formed. Good too.

Furthermore, a plurality of holes may be formed at appropriate locations in the door body 10 by punching or the like.

6 and 7 respectively show other embodiments of the present invention, FIG. 6 shows one in which only one lattice member 12 is formed on the door body 10, and FIG. 7 shows another embodiment of the door body 10. 2 shows a structure in which a plurality of lattice members 12 are provided in two stages, upper and lower.

[Effect of idea]

As explained above, the door of the present invention is formed into a cylindrical shape by a face plate part that extends between the upper and lower parts of the door body, and a bent plate part that is connected by bending both left and right ends of this face plate part. Since the lattice material is equipped with a lattice material and horizontal bars that cover the openings at both the upper and lower ends of the lattice material, when forming the cylindrical lattice material on the door body, it is necessary to perform, for example, punching and then bending. In addition, to cover the openings at both the top and bottom ends of the lattice material,
It is easy to manufacture the horizontal beams by simply fixing them by welding or the like.

In addition, in the door of the present invention, the lattice material is cylindrical, and the openings at both the upper and lower ends of the lattice material are covered by horizontal bars, so even though the door is made of a lattice material formed by bending a metal plate, The door is safe for pets because it does not catch hands, feet, or body hair, and since the horizontal bar acts as a reinforcing material for the door body, the door is strong and beautiful as a whole.
