Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing animals (especially rats) from entering through a shutter and a shutter opening when the shutter is lowered.

[0002]

2. Description of the Related Art At present, there is a problem that a mouse enters through a shutter opening. Shutters installed in various buildings are stored in the direction of the ceiling when they are open, and the rat cannot pass through because the seat plate closes the shutter opening. However, when the shutter is lowered, a gap of about 2 cm is generated before and after (on both sides) between the shutter opening of the ceiling and the shutter. The mouse moves up and down using the irregularities of the slats of the shutter skillfully, and moves in and out of the room through the gap.

[0003]

Problems to be solved by the present invention
It has been common practice to use a flat plate material and screw one end thereof to a magsa forming a shutter opening so as to close the gap. This flat plate material is a retrofit type, and must be measured one by one at each installation location and made one by one. Especially when the shutter is curved
The plate material had to be cut into a shape corresponding to the curved state, and if the seat plate had a square cross section, the flat plate material was processed into a shape following the square shape, and that processing had to be done at the press factory Instead, it was very troublesome.

[0004] Therefore, an object of the present invention is to provide an animal intrusion prevention device which is light in weight and simplifies construction, in order to prevent the above-mentioned disadvantages.

[0005]

According to the present invention, there is provided an animal intrusion prevention apparatus, comprising: a shutter which is drawn out of a shutter storage section through a shutter opening, wherein a gap between the shutter in the shutter opening and the shutter opening is provided. And an elongated member is arranged along the shutter (claim 1).

[0006] Accordingly, the size of the gap formed along the shutter is reduced by the elongated member disposed in the gap between the shutter and the shutter opening, and the animal (mouse) cannot pass through.

The elongated member has a round cross section (claim 2) or a square cross section (claim 3). The round cross section has an advantage that rat teeth do not stand. is there. Further, the elongated member has a number of sharp projections in its longitudinal direction (claim 4), and prevents the animal from pushing through the elongated members while avoiding the sharp projections.

[0008] Both ends of the elongated member are fixed to a guide rail or a magsa constituting a shutter opening by a mounting bracket (claims 5 and 6). In the mounting bracket, the elongated member is formed between the shutter and the opening. Can be easily installed in between.

Further, the position of the elongated member is corrected by a gap correcting material in the middle thereof (claim 7), so that the position of the elongated member is corrected when the shutter is bent so that the animal does not pass through. It has the advantage of being corrected to a small size.

[0010] In addition, as the elongated member, a wire such as a wire, a pipe, a round bar, or the like is used.
10).

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example in which a shutter 1 is mounted on a building and the shutter 1 is lowered. The shutter 1 is formed by connecting a number of slats, the base end of which is connected to the winding shaft 2 and the seat plate 5 is provided at the end. When the shutter 1 is raised,
It is wound on the winding shaft 2.

The winding shaft 2 is generally housed in a shutter housing space 4 constituted by a shutter housing case 3. Although not shown, the winding shaft 2 is rotated by a spring or a motor to wind the shutter.

The shutter opening 6 is where the shutter 1 enters and exits.
The shutter 1 includes guide rails 8 provided at both ends thereof, and as shown in FIG. 2 when viewed from below, the shutter 6 is disposed in the opening 6 in the longitudinal direction.

[0015] Between the shutter opening 6 and the shutter 1, gaps 6a and 6b are provided on both sides thereof. This is a space necessary for the shutter 1 to move smoothly and has a size of about 2 cm. Therefore,
A rat that can be active if there is a space of about 1.5 cm can enter and exit through the gaps 6a and 6b.

Therefore, as shown in detail in FIG. 2, an elongated member 9 such as a wire is positioned in the middle of the gaps 6a and 6b along the longitudinal direction of the shutter opening 6, and is stretched. Specifically, as shown in FIG. 3, the opening 6 is attached to mounting brackets 10, 10 attached to the guide rail 8 of the opening 6.
It is fixed to.

The mounting bracket 10 is shown in FIG. 4. A slit is formed in the upper locking portion 10a, a screw hole 12 is formed in the lower fixing portion 10b, and the elongated member 9 is formed in the slit 11.
Are inserted and engaged, and are fixed to the guide rail 8 by screws 13 through screw holes 12. In addition,
The mounting bracket 10 has not only one slit 11 but also two slits as shown in FIG.

The elongated member 9 is a metal wire, a resin cord, a thin rod, a connecting member for a number of balls, etc., and has a diameter of 1 mm.
mm ~ 3mm, 4mm ~ such as pipes and round bars
Those having a diameter of about 10 mm are used, and have a round or square cross section. In the case of the round shape, there is an advantage that rat teeth do not stand. Although not shown, a sharp protrusion may be formed on the wire to prevent the mouse from contacting and pushing out. An engagement ring 15 is attached to an end of the elongated member 9. When the engagement ring 15 is inserted into the slit 11, the engagement ring 15 is engaged with the mounting bracket 10.

FIGS. 6 and 7 show an example in which an elongated member (for example, a wire) 9 in a case where the shutter 1 is curved is attached. That is, an example is shown in which a plurality of elongated members 9 are used when the gaps 6a and 6b between the shutter 1 and the shutter opening 6 cannot be completely blocked by one elongated member 9. One side of the gap is two,
Moreover, since the gap is wide at the center, the gap correction material 1 is used to adjust the gap between the two elongated members 9.
6, so as to keep an appropriate gap of about 1 cm. In the case of the present embodiment, when the shutter 1 is curved to maintain an appropriate gap, the gap correcting material 1
6 is used.

As shown in FIG. 8, the gap correcting member 16 has a base end 16a attached to the magsa 7, and an elongated member 9 inserted into holes 17, 17 formed in the main pillar 16b at the tip end. .

In the above configuration, to attach the elongated member 9 to the shutter opening 6, first, a fitting 10 is attached to the inside of the guide rail 8 of the opening 6. Then, the ends of the elongated members 9 are respectively inserted into the slits 11 of the mounting bracket 10.
To complete the engagement. As a result, the gap becomes shorter than the size through which the mouse can pass, thereby preventing entry and exit. If the shutter is curved, the installation position is corrected using the gap correction material 16 that corrects the position according to the state of the shutter 1.
When an appropriate gap cannot be obtained with one elongated member 9, two or three or the like can be used, and a gap correction material 16 is used to make the dimension between the elongated members 9 appropriate. Things.

In this embodiment, the mounting bracket 10
Has been described only on an example of attachment to the guide rail 8 of the shutter opening 6, but it may be attached to the magsa 7 or to a building. The attachment between the attachment fitting 10 and the elongated member 9 is performed by engaging the elongated member 9 with the slit 11 as in the above-described example. Is also good. Further, as described above, although the description has been given mainly of rats, it is possible to prevent birds and the like from entering.

[0023]

As described above, according to the present invention, since the elongated member is disposed in the gap between the shutter and the shutter formed in the shutter opening, the gap becomes smaller than the size of the animal such as a mouse. To prevent animal invasion. Further, the attachment of the elongated member has an advantage that it is much simpler than the attachment of the conventional flat plate material, and it can be provided at a low cost with few parts. This has the effect of making it very easy to retrofit existing shutters.
