【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the insect screen apparatus of the present invention, as shown in FIG. 3, the insect screen 4 is wound and unwound by the tension of the winding spring 13, and the spring 13 is set to the inner shaft groove 12d of the bobbin 12. It is installed in the housing housing fixing cap 14 of FIG. 1 and the insect net 4 is wound or pulled out by the rotation of the bobbin 12.

The bobbin 12 is provided with a flange 12 a, is formed so as to be symmetrical on both left and right sides, and forms an insertion shaft 12 b having a fitting groove corresponding to the key groove 10 a formed on the winding rotary shaft 10. Has been done. By inserting the insertion shaft 12b into the journals at the left and right ends of the winding shaft, the bobbin shaft 12c is connected to the boss 14a of the storage housing cap 14 and serves as a rotating shaft of the winding shaft 10. The winding shaft 10 is formed with key grooves 10a connected to the upper end of the insect screen (4) up to the left and right ends, and the height of the side wall at points A and B of this key groove corresponds to the thickness t of the insect screen. Since the difference is provided by that amount, the insect screen 4 can be wound around the winding shaft 10 without causing deformation.

As shown in FIG. 1 (a), the insect net housing 1 having a semi-circular structure is vertically fastened integrally with the insect net support 2 at both left and right ends, and is connected to the rear end of the housing. The part 1b is installed toward the outside of the existing window frame 20. Further, as shown in FIG. 2, at the bottom end 1c of the housing extending from the front face 1a and the rear end 1b of the housing housing 1, the front face 1a is formed to be longer than the bottom end 1c. Therefore, when the insect repellent net body 3 is wound around the winding shaft 10, the lower part of the insect repellent net body 3 is housed so as not to spoil the appearance.

As shown in FIGS. 1 (b) and 4, the insect net support 2 is provided with a slide groove 2 d which is inserted into the insect net 4 to assist the insect net 4 in ascending / descending action. A gap 2c having a constant width is formed in the vertical direction at the inner end of the slide groove 2a of the insect net support 2, which is 1.2 to 3 times thicker than the thickness. Further, the insect-proof net support 2 is reinforced in strength by inserting a reinforcing support 16 inside.

As shown in FIG. 4, the left and right journal portions 17a of the fixed horizontal rod 17 connected to the inner side of the handle 5 at the lower end of the insect screen enter the inside of the slide groove 2a and have a predetermined frictional force when moving up and down. To give. That is, when the insect-preventing net 4 is wound around the take-up shaft 10 by unlocking the locking device 6a, the tension of the spring 13 rapidly raises the insect-preventing net 4. As a result, the ascending speed slows down, and when the user pushes it, a two-step ascending action that immediately ends the ascending is performed.

When installing a conventional insect netting aggregate on a window frame, it is fixed to the window frame with bolts and nuts by a normal method. At this time, the insect screen is installed between the window frame and a predetermined interval so that the window can be opened and closed. It was installed with a gap. Therefore, as shown in FIG. 4, the insect screen could not completely provide the insect-proof sealing property with the existing window frame 20 and the predetermined space formed. Therefore, in this invention, the sealing layer 18 made of a brush, a non-woven fabric, rubber, a plastic synthetic resin material or the like is fitted to the shielding layer fitting portion 2d of the insect net support 2, thereby ensuring the hermeticity with the window frame 20. I am doing it.

The shielding layer 18 of the present invention not only provides a simple sealing action, but removes dust and dirt adhering to the window each time the window is opened and closed, so that it does not come in contact with human hands. The parts are also cleaned if possible. A general synthetic resin net, a natural fiber net or a metal net can be used as the insect net 4 of the present invention, but it is particularly excellent in various characteristics such as heat resistance, weather resistance and impact resistance. It is preferable to use an alloy material (for example, aluminum alloy or stainless alloy material).

When the insect net 4 of the present invention is made of a metal material such as aluminum or stainless steel, the fixed horizontal rod 17 at the lower end of the insect net 4 and the shape retaining reinforcements 19 at the left and right ends are soft. The end portions of the net body may be finished with a shock-resistant synthetic resin material or a plate-shaped thin stainless steel material to prevent deformation. The part of the shape retaining reinforcement 19 at the left and right ends that is in contact with the gap 2c of the slide groove 2a of the insect net support 2 has an enlarged structure. As shown in FIG. 4, it is sufficiently thicker than the width of the gap 2c. Even if the opening and closing of 4 is continuously repeated, the gap 2c does not easily enter, so that the opening and closing can be smoothly performed.

If the shape-retaining reinforcement material 19 is a synthetic resin reinforcement material, in order to improve the bondability with the metal insect repellent net 3, a high-frequency heat fusion method or a thermoplastic synthetic resin is used. It is also possible to manufacture by injecting a thermoplastic resin to the left and right ends of the insect net 4 spread to the left and right by a press injection method, or by a compression bonding method performed at the plasticizing temperature. As shown in FIG. 6, such an insect-proof net 4 is constituted by a pin 6c fixed to the handle 5 in a locking device 6a of the locking means 6 at the lower end, which is fitted by a long hole 6b. The bar 6a performs a locking action while the bar 6d is inserted into or discharged from the bar supporting portion 2d of the insect net support 2.

That is, if the insect net 4 is to be installed, when the handle 5 at the lower end of the insect net 3 is grabbed, the insect net 3 is unwound from the winding portion and the slide groove 2a of the insect net pillar 2 is removed. When it comes to descend while rubbing and reaches the bottom end of the insect net support 2, it pushes up the locking device 6a having a wide upper part downward and pushes the contact surface 6g of the bar 6d to the left and right. Since it is inserted into the bart supporting portion 2d while protruding leftward and rightward, even if the force for pushing down the insect net 4 by hand is removed, it remains fixed.

If the insect screen 3 is to be opened, the locking device 6a may be pushed up, as shown in FIG. As shown in FIG. 5, the fixed horizontal rod 17 for fixing and supporting the insect screen 4 has a chevron-shaped projection 17c formed at the center of the slit 17b formed in the axial direction. Secure the net 4 firmly. When the insect net 3 is opened and housed in the insect net housing 1, it does not hinder the opening / closing operation of the window.

The fixed horizontal rod 17 is inserted into the internal insertion groove 5 a of the handle 5, and the concave and convex portion 17 c is strongly meshed by the compressive force of the handle 5 to prevent the insect net 4 from coming off. On the other hand, the handle 5 is provided with comb-shaped concave and convex portions 5b on the inner side surface up to the left and right ends so as to be tapered upward in the axial slit 5a so that the fixed horizontal rod 17 is not deformed even when it is used for a long time. The mechanical stability is strengthened.

When the conventional insect repellent net is installed for a long time, there is a problem that fine dust adheres to the net due to an electrostatic phenomenon and impairs the aesthetic appearance, and the mesh is blocked to prevent air circulation. there were. However, as described above, the housing housing 1 for winding installed on the upper part of the insect net support 2 of this invention is provided with the fitting portion 1d into which the net brush 15 is fitted. Since the brushes 15 are arranged in rows at the upper end of the insect screen 4 and are installed so as to press the insect net 4, the net brush 15 sweeps the entire insect net 4 when the insect net 4 is raised. Then, the dust and dirt adsorbed can be removed. Therefore, the user does not need to separately clean the insect screen, and the insect screen 4 can always be used cleanly by repeating only the opening and closing action.

As described above, according to the insect screen apparatus of the embodiment of the present invention, the barb 6d is inserted into the aggregate by the sliding frictional vertical movement of the locking device 6a, so that the structure is extremely stable. Can be held. In addition, by installing a mesh brush 15 or the like in the winding section, a perfect airtightness is ensured, and the insect net 3 and the window can be kept clean. Furthermore, since the left and right ends of the insect repellent net body 3 made of a metallic material are fixed by the shape-retaining reinforcements 19, the deformation is less likely to occur than that of the conventional synthetic resin material net body.

At the lower end of the insect screen device, the fixed horizontal rod 17 and the handle 5 doubly fix the insect screen 4, so that the net body is hardly detached and the sliding groove 2a and the appropriate friction are maintained even when the net is raised or lowered. Since the force is maintained, a rapid rise can be prevented, and a constant space is maintained in the gap 2c so that the mesh does not rub. Further, since the shape retaining reinforcements 19 at the left and right ends are also thickened on the inner side, even if the insect repellent net body 3 is repeatedly opened and closed, the net body is prevented from coming off, and the shape is not deformed.

The locking device 6a in the above embodiment can be configured by using an elliptical rotary cam, and is not limited to the above.

[0030]

[Effect of device]

 As is clear from the above description, according to the insect net device of the present invention, the strength of the insect net is enhanced, and the sealing property of the window frame is also enhanced. In addition, the insect repellent function can be maintained for a long time without the netting coming off or the shape being deformed, and it can be used without impairing the aesthetic appearance.
