The mesh 200 may be a mesh in which a wire is woven in a mesh structure. The wire may be formed of metal or plastic, glass fibers, for example. Air flows through the mesh grooves defined by the wires. One part of the mesh 200 is connected to the cassette 100 and the other part is connected to the handle 300.

The handle 300 can be moved between a position away from the cassette 100 (see FIG. 1) and a position close to the cassette 100 (see FIG. 2). The handle 300 may have a smaller size than the cassette 100.

Rail assembly 400 extends to connect adjacent ends of cassette 100 and handle 300. The rail assembly 400 may be formed to receive both ends of the mesh 200.

The fixed unit 500 may include a pair of members formed to interlock with the handle 300 and the rail assembly 400. Thereby, the fixing unit 500 causes the handle 300 to be fixed in the deployed position (see FIG. 1). The operation lever 530 for releasing the fixing of the handle 300 may be installed in the handle 300.

Connecting table 600 is a configuration for connecting the free ends of the pair of rail assembly 400 to each other. Connecting rod 600 is generally arranged parallel to winding cassette 100. The connecting rod 600 may be referred to as a frame together with the rail assembly 400.

This insect repellent device may not work in conjunction with opening and closing of the window. In other words, the cassette 100 or the handle 300 is not fixed to the window, but may have a form fixed to the window frame.

A portion of the net 200, for example the top 210, is connected to the roll 120. The roll 120 is for winding the net 200, and the length may be determined corresponding to the width of the net 200. One end of the roll 120, specifically the left end in the drawing, is rotatably supported by a support 125 that is coupled to the rail assembly 400.

The elastic body 130 is a member for accumulating or dissipating an elastic force. For example, when the mesh 200 is pulled to be unrolled from the roll 120, the elastic body 130 is stretched to accumulate elastic force. On the contrary, while the mesh 200 is wound on the roll 120, the elastic body 130 provides a force for the mesh 200 to be wound on the roll 120 by releasing the accumulated elastic force. To this end, the elastic body 130 may be, for example, a torsional spring. To elastically wind the roll 120, one side of the elastic body 130 is coupled to a fixing table 135. This fixing table 135 is non-rotatably engaged with the inner surface of the roll 120. [

The connecting portion 721 is a portion to which the elastic body 130 (Fig. 3) is connected. The connecting portion 721 may have a size to be inserted into the hollow portion of the roll 120 (Fig. 3). The connection portion 721 may have a size to be inserted into the elastic body 130, specifically, the hollow portion of the coil spring.

The support 722 is also inserted into the hollow portion of the roll 120 to support the roll 120 in rotation relative thereto.

The connecting cylinder portion 723 accommodates the slider 730. Specifically, the connecting cylinder portion 723 may include a first hollow portion 724 and a first latching projection 725. The first hollow portion 724 forms an open space in the direction toward the slider 730. The first locking protrusion 725 protrudes from the inner circumferential surface of the first hollow portion 724. The first latching protrusion 725 may extend along the longitudinal direction of the body 110. The first locking protrusions 725 may also be formed as a plurality of spaced apart at regular intervals along the circumferential direction of the inner circumferential surface of the first hollow portion 724.

The slider 730 has a generally cylindrical shape, and both ends thereof are formed to be inserted into the coupling member 720 and the cover module 750, respectively. Specifically, the first recess 731 is formed on the outer surface on one end side of the slider 730, and the second recess 733 is formed on the outer surface of the other end side. Here, the first recess 731 and the second recess 733 may extend along the longitudinal direction of the body 110. The first recess 731 is formed to slidably receive the first latching protrusion 725 of the slider 730. The second recess 733 is formed to slidably receive the second latching protrusion 777 of the cover module 750. On one side of the slider 730, a tool groove 735 is formed. The tool groove 735 is formed corresponding to the through hole 761 of the cover module 750 and may be formed to have a hexagonal cross section corresponding to the hexagonal wrench. It is also possible to form the cross-sectional shape of the tool groove 735 in a rectangular or octagonal shape in addition to a hexagonal shape.

The cover module 750 may include a plate 760 and an engagement member 770.

The plate 760 is configured to cover the other end 112 of the body 110. The plate 760 may include a main portion 760a and an auxiliary portion 760b. The main portion 760a is a portion to be coupled to the other end portion 112 of the body 110 and the auxiliary portion 760b is a portion to be fitted to and joined to the rail assembly 400. [ A through hole 761 is formed at the center of the main portion 760a. At the edge of the main portion 760a, a fastening hole 763 for inserting a screw for fastening with the body 110 may be formed.

The engaging member 770 is protruded from the main portion 760a while communicating with the through hole 761. [ The engaging member 770 may include an engaging cylinder portion 775 formed to receive the slider 730. The engaging cylinder portion 775 may include a second hollow portion 776 and a second locking protrusion 777 protruding from the inner surface of the second hollow portion 776. The second hollow portion 776 is formed to have a size capable of accommodating the slider 730 and is formed to communicate with the through hole 761. The second locking protrusions 777 may extend along the longitudinal direction of the body 110 and may be formed at a plurality of spaced intervals along the circumferential direction of the second hollow portion 776.

The biasing member 780 is configured to deflect the slider 730 toward the cover module 750 with respect to the connecting member 720. [ For this purpose, the biasing member 780 may be a coil spring installed in the first hollow portion 724 of the connecting member 720.

The operation of the tension control assembly 700 according to the above construction will be described with reference to FIGS. 5 and 6. FIG.

5 is a cutaway perspective view for explaining a state in which the slider 730 is engaged with the engaging member 770 in the tension adjusting assembly 700 of Fig. 3, Fig. 6 is a perspective view of the slider 730 in the tension adjusting assembly 700 of Fig. 730 are released from the engagement with the engaging member 770. As shown in Fig.

5, the first recess 731 of the slider 730 is engaged with the first latching protrusion 725 of the connecting member 720 in the initial assembled state. The second recess 733 of the slider 730 is engaged with the second latching protrusion 777 of the cover module 750. Thereby, the connecting member 720, the slider 730, and the cover module 750 are not rotated about the axis along the longitudinal direction of the body 110. [ As the connecting member 720 is not rotated, the elastic body 130 connected to the connecting member 720 is also not rotated. This is the same even if the tool is inserted into the tool groove 735 of the slider 730 through the through hole 761 to give a force.

6, in order to adjust the tension of the elastic body 130 by rotating the elastic body 130 in the state of FIG. 5, the tool T is first inserted into the tool groove 735 through the through hole 761, (730) with respect to the connecting member (720). Thereby, the first recess 731 of the slider 730 is inserted still further into the first hollow portion 724 while the slider 730 is still engaged with the first latching projection 725 of the connecting member 720 . The movement of the slider 730 causes the second recess 733 of the slider 730 to come off the second latching protrusion 777 of the engaging member 770. [ Thereby, the slider 730 is released from the engagement state with the engaging member 770, and becomes rotatable about the axis along the longitudinal direction together with the connecting member 720.

When the slider 730 receives the rotational force by the tool T in the upper rotatable state, the slider 730 rotates together with the connecting member 720. [ Thereby, the elastic body 130 connected to the connecting member 720 can be rotated without clockwise or counterclockwise distinction. This means that the twist degree of the elastic body 130 can be adjusted to be strong or weak, and it also means that the roll 120 can be wound or unwound.

After the elastic body 130 is rotated to a desired level, the slider 730 can be retracted to engage with the engaging member 770 again. This retraction can be accomplished manually using the tool T and, moreover, automatically by the biasing member 780. [ In the latter case, after the biasing member 780 is compressed by advancing the slider 730 into the connecting member 720, the force applied to the slider 730 is restored when the force applied to the slider 730 is removed or weakened, (770). ≪ / RTI >

The process of manipulating the tension of the elastic body 130 can be performed simply by using a tool from the outside, without having to disassemble the winding cassette 100.

Such a winding cassette for a winding insect repellent device, a winding insect repellent device having the same, and a tension adjusting assembly used therein are not limited to the configuration and manner of operation of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
