JPS581595Y2 - screen door - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a new screen door.

Conventionally, sheds for large and other small animals kept in general households are usually built using ambient water, but although this is good in the cold winter months, ventilation is poor in the summer months, making it uncomfortable to live in.

In order to improve this, a screen door with a wire mesh is installed at the entrance or part of the surrounding area, which provides good ventilation and prevents mosquitoes, flies, etc. from entering, that is, prevents insects. It is good to be able to do it.

However, when using such a screen door, the wire mesh is often damaged by the feet or claws of large animals, causing it to break and become unusable.

Thus, the purpose of the present invention is to provide a screen door that will not be damaged by the feet or claws of small animals, especially for use in small animal breeding sheds. It has been discovered that the above object can be achieved by fitting an inner frame having expanded metal on the inside between the upper and lower edges of an outer frame having upper and lower edges.

To explain the present invention in more detail with respect to one embodiment thereof,
1 is usually a rectangular or square outer frame of an appropriate size,
Aluminum or iron (e.g. thickness 0.8-1.2m/m
It is made of metal such as iron plate.

This outer frame 1 is formed into a mesh shape with vertical and horizontal crosspieces 2 usually provided at equal intervals on the front side, and bent extensions of a certain length are provided at the upper and lower parts to form edges 3, 3. Form.

For example, a mesh 2 is provided on the inside of this outer frame 1, that is, on the edge forming side.
A regular steel insect-proof wire mesh 4 of m/m is attached over the entire surface.

On the other hand, 5 is an inner frame of a size that fits into both edges 3, 3 of the outer frame, and a remaining part 6 is provided at the same position as the outer frame 1 to form a mesh shape, and similar edges are provided at the upper and lower parts. Sections 7 and 7 are being made.

The inner frame is usually made from an iron plate with a thickness of 0.8 to 1.2 m/m.

The expanded metal 8 is similarly attached to both edges by spot welding over the entire surface.

Expanded metal is a durable wire mesh made by making cuts in an alloy plate or iron mesh plate and pulling it uniformly to create uniform gaps.
41) is preferably used.

Incidentally, depending on the size of either or both of the outer frame and the inner frame, it is also possible to leave only the periphery without forming the crosspiece and leave the entire front surface open, or to form it only in either the vertical or horizontal directions.

As described above, between the upper and lower inner edges of the outer frame 1 with the wire mesh attached on the inside, the inner frame 5 with the expanded metal 8 attached on the inside in the same way is fitted and pressed together to form a screen door, When in use, the expanded metal 8 is placed on the inside of the shed, that is, on the side that comes into contact with small animals.

When using the screen door of the present invention constructed in this way, the outer frame 1, the wire mesh 4, the inner frame 5, and the expanded metal 8 are arranged from the outside.
The wire mesh 4 is sandwiched between the inner frame 5 and the outer frame 1, and does not come into direct contact with small animals, so that it is not damaged, broken, or contaminated by their feet or claws.

The side that comes in contact with small animals is equipped with durable extra band metal, so it will not be damaged by mosquitoes, mosquitoes, etc.
Invasion of flies can be completely prevented.

In addition, although extended metal with relatively large gaps does not provide complete insect protection, a steel wire mesh is provided on the outside, which is good in terms of insect prevention and ventilation.

Further, since the inner frame is fitted within the edge of the outer frame, the wire mesh and the expanded metal can be well fixed while maintaining a distance between them.

Moreover, this four-layer structure does not impair breathability in any way.

Thus, when using the screen door of the present invention, it is not damaged by the claws, feet, etc. of small animals, completely prevents the intrusion of mosquitoes and flies, and provides sufficient ventilation, which is very good.

Of course, it can be used not only for dog kennels, but also for places in general houses and buildings that are likely to receive shocks.

Therefore, the present invention can provide a truly effective screen door of this type.
