Description

[Detailed explanation of the invention] This invention relates to an insect screen that is attached to the outside of the ventilation opening to prevent small insects from entering through the ventilation opening provided on the side wall or the upper part of the front wall of a dog kennel. The purpose of the present invention is to provide an insect repellent net that can reliably cover ventilation openings with simple operation.

One embodiment of the present invention will be described with reference to the drawings. The mesh frame 1 has an internal surface formed from a rectangular peripheral edge 1a in a uniform bulge shape, and three circular openings 1c are arranged in parallel on the bulge surface 1b. A fine mesh 2 is stretched over the inner surface of the opening of the mesh frame 1, and an appropriate number of engaging pieces 3 each having a tip 3a bent into a triangular shape on the side are protruded at appropriate locations on the bulged inner surface. The engaging piece 3 is shown in FIG. 2 in order to attach the insect screen A to the outside of a shutter-shaped ventilation opening 4 formed by punching out the upper part of the side wall of the dog house B. As shown in FIG. 3, the net frame is inserted between the upper and lower armor plates 4a arranged in parallel, and the lower edge of the tip 3a is engaged with the inner edge of the lower armor plate 4a by pressing the net frame inward as shown in FIG. By engaging the upper end with the inner end of the upper armor plate and fixing the entire insect screen, the peripheral edge 1a of the insect screen frame 1 is brought into close contact with the outer peripheral wall surface of the ventilation opening 4.

In FIG. 1, reference numeral 5 denotes an insect screen protruding from the front wall window, and reference numeral 6 denotes an insect screen protruding from the front door window.

The present invention has the above-described configuration and has the following effects.

The internal surface of the mesh frame is bulged from the peripheral edge, the mesh is stretched over the opening of the bulging surface, and it is pressed against the outside of the ventilation opening, so that the bulging surface 1b is fitted to the outside of the protruding armor plate and mounted on the peripheral edge. 1a can be brought into close contact with the outer circumferential wall of the ventilation opening without any gaps, and small insects can be reliably prevented from entering through the joint.

Moreover, if the engaging piece 3 provided inwardly protruding inside the bulging surface is inserted from between the upper and lower parallel armor plates 4a, the lower side of the triangular bent portion of the engaging piece tip 3a will engage with the inner end of the lower armor plate. At the same time, its upper end engaged with the inner end of the upper armor plate, and in this case, the elasticity of the armor plate acted from both the upper and lower sides at the engaging portion, making it difficult for the mesh to disengage, and therefore the entire mesh frame reliably covered the ventilation opening. Due to the elasticity of the members fixed in this state, the peripheral edge of the screen frame can be brought into even closer contact with the outer peripheral area of the ventilation opening. Furthermore, when removing the insect screen, if the engaging piece is pulled out against the elasticity of the armor plate, the engagement is released and the screen frame is easily separated from the ventilation opening.

As described above, the insect screen of the present invention can be attached to and removed from the ventilation opening by means of the engaging pieces 3, and can effectively prevent small insects from entering through the ventilation opening.
