Fig. 3 is an exploded perspective view of the upper end of the storage case 2L constituting the vertical roller window, and the guide lid 4c fitted to the upper guide rail 32a on the upper lid briquette 4 and traveling in the lateral direction. Is formed, and is fixed to the upper end of the storage case (2L) and simultaneously posts the levers (7a) (7b) is fixedly stored on both sides of the guide groove (4c) in the upper lid briquette (4) wound spring (10) As a shot in the direction that is separated from the upper rail (32a) as a latch 9 is inserted in the opening of the lower surface of the upper lid briquette (4), the front end of the jaw (9b) of the two branches branched The inner inclined surface is rigidly engaged with the tip inclined surface 7d of the levers 7a and 7b so as to release the upper frame rail 32a in accordance with the opening and closing operation of the levers 7a and 7b. Herein, the latch 9 is pressed in the pocket 9a, in particular as shown in FIG. (11) and at the same time the tip of the pressing spring (11) is in contact with the lower surface of the upper lid briquette (4), when the latch (9) is shot downwards and the inner inclined surface and the lever ( Strongly engages the tip inclined surface 7d of 7a) and 7b so that the levers 7a and 7b are closed so that the upper frame rail 32a is not clamped, while a fixed connection to the latch 9 thereof. An electric lower lower latch 8 is connected to the lower end of the interlocking interlock 2c, and the levers 7a and 7b of the lower lid briquette 3 also sandwich the lower frame rail 33a at the same time. have.

4 and 5, "12" indicated as a latch is fitted to the upper end of the shaft 17 inserted into the take-up shaft 13 of the mantle 1R, so that idling is constrained by the projection 12a. In addition, "14" is a torsion spring, and both ends thereof are fixed to the spring terminals 15 and 16, and one spring terminal 16 has the protrusion 16a engaged with the slit 13a of the winding shaft 13; To the idle winding 13, the other spring terminal 15 is fixed to the lower end of the shaft 17, the upper end of the shaft 7 is fixed to the boss 18a of the cover 18 , The lid 18 is fixed to the upper lid briquette 4 in a detachable manner.

And "19" is a braking plate, the jaw (19a) engaging with the latch 12 is formed at the tip of the semi-circular inner circumferential surface formed to surround the latch 12 protruding from the upper end of the take-up shaft 13, the other end The pressing spring 20 is disposed in the guide hole formed in the flange (19b) bent downward, the braking plate (19) is attached to the guide groove (4b) of the upper lid briquette (4) As the tip of the pressing spring 20 is shot in contact with the vertical wall of the upper briquette 4, the jaw 19a of the brake plate 19 is engaged with the latch 12. Rotation is constrained in the rotational direction (clockwise) in which the web 1 is expanded, that is, the rotation of the web 1 of the winding shaft 13 of the winding shaft 13 of the mesh roll rotated integrally with the latch 12 is rotated. It was for redemption.

An inclined surface 19c is formed at the lower end of the vertical flange 19b of the braking plate 19, and the latched end branched at the distal end of the latch 9 is engaged with the inclined surface 9c provided at the upper edge. Therefore, when the latch 9 is moved upward to stop the levers 7a and 7b, the inclined surface 9c of the latch 9 presses the inclined surface 19c of the brake plate 19 to press the spring 20. ) By moving the braking plate 19 in the lateral direction while compressing the) and the engagement between the jaws 19a and the latched 12 of the braking plate 19 is terminated. Clockwise rotational constraints can be released.

On the contrary, when the latch 12 is lowered to lock the levers 7a and 7b, the brake plate 19 is fed back by the pressing elastic piece 20 and again the jaw 19a and the latch of the brake plate 19 are applied. (12) becomes pressure.

Fig. 6 is an external view of the drive handle 21 constituting the above-mentioned vertical roll window, in which the drive handle 21 is integrally formed with the pinion 22 at its tip. The rack gear 23 to be engaged is internally stored in the gear case 24 vertically, and at the same time, between the tip of the rack gear 23 and the ceiling wall of the gear case 24 which are internally stored in the gear case 24. The coil-shaped press spring 25 is arrange | positioned and the lag gear 23 is always shot below by the press spring 25. That is, the drive handle 21 is fixed to the gear case 24, the gear case 24 is fixedly disposed in the middle of the storage case (2L), the rack gear 23 is fixedly engaged to the interlocking groove (2c) Therefore, when the drive handle 21 is rotated, the lex gear 23 slides upward while compressing the pressing spring 25 and raises the interlocking motion 2c simultaneously. On the contrary, when the drive handle 21 is released, the compressed pressing spring 25 is elongated, and the interlocking rod 2c also slides downward. Thus, the latch 9 connected to the interlocking rod 2c is operated to move up and down. Control of pinching or opening by the levers 7a and 7b with respect to the rails 32a and 33a and the rotation of the take-up shaft 13 is performed so that the jaws 19a of the brake plate 19 and the latch 12 are controlled. The engagement can be made at the same time.

As described above, in the present invention, as illustrated in FIG. 2, the lower lid briquettes 3 fixed to the lower ends of the storage cases 2R and 2L are detachably fitted to the lower frame rails 33a and 33b. In addition, the transverse traveling is freely performed in the upper and lower frames 32 and 33 supported by the door car 5 stored in the lower lid briquette 3.

In this way, the sliding sliding chassis is a left and right window (35R) (35L) that allows to cover the normal single-glazed glass irrespective of the general model, its left and right vertical frame (36R) (36L) is almost a common dimension to support it. And the spacing of the lower frame rails 33a and 33b and the spacing d with the rails 33a and 33b parallel to the windows 35R and 35L, the spacing d of which is It is around 23mm. As described above, the mesh roll 1R is wound around the winding shaft 13 of about ø10 mm, and the mesh width of 850 to 900 mm is wound around the ø19 to 20 mm. It is internally stored in the storage cases 2R and 2L so as to be stored in the space d between the rails 33a and 33b, and the end of the net 1 is adhesively fixed to the net press hoop 6 made of synthetic resin. At the same time, the mesh pressing hoop 6 is detachably fitted to the guide groove 34a of the flat "C" cross section of the chassis frame 34. Furthermore, the guide groove 34a of the bell 34 is made separately from the chassis, for example, made of synthetic resin extrusion, so that it can be bonded or screwed to the bell 34, and thus it can be installed in the existing chassis door. It is.

And, the lower lid bracket 3 fixed to the lower end of the storage case 2R (2L), unlike the above-mentioned door car 5, the lever (7a) to securely clamp the chassis lower frame rail (33a) 33b detachably. The levers 7a and 7b, which are stored in a lower lid briquette 3 fixed to the lower end of the storage case 2R and 2L, are 7a and 7b. It is fixedly connected to the lower end of the interlocking rod 2c slidably inserted into the guide groove 2a of the storage case 2 in the same shape as the levers 7a and 7b fixedly stored in the upper lid briquette 4 shown. It is press-engaged with the inclined surface of the latch front end part of the latch 8 which exists, and clamps and fixes the chassis undercarriage rail 33a, 33b strongly, and also pulls a storage case 2R (2L) laterally and a mesh ( In the case of expanding and installing 1), the frictional resistance is large in the levers 7a and 7b so that the lower lid briquette 3 does not deviate in the returning direction. Will be used as a free (7c).

Therefore, since the vertical roll screen (first embodiment) of the present invention is constructed as described above, the bells are shifted from each other, that is, the storage case is to be expanded and installed in the sliding aluminum chassis. When the driving handle 21 of 2L is rotated to the front, the pinion 22 and the engaged rake gear 23 are raised while compressing the pressing spring 25 in which the pinion 22 is integrally installed. ), And the latches 8 and 9 fixed to the upper and lower ends of the interlocking rod 2c are raised so that the inner inclined surface of the latch tip jaw 9b is weaker than the front inclined surface 7d of the levers 7a and 7b. While the latches of the upper and lower rails 32a and 32b of the upper and lower openings of the upper and lower frames are opened by the levers 7a and 7b that are engaged and posted, the latch inclined surface 9c is accompanied by the rise of the latches 8 and 9. Since the inclined surface 19c of the brake plate 19 is pressed to compress the pressing spring 20, the brake plate 19 is moved in the lateral direction. Since the engagement of the jaw 19a of the brake plate 19 and the latch 12 is released and the clockwise rotational constraint of the latch 12 and the take-up shaft 13 is canceled, the drive handle 21 thereof is rotated. When the storage case 2L is pulled laterally and the inside of the upper and lower rails 32a and 33a of the opening upper and lower frames 32 and 33 are slid, the net 1 is drawn out from the storage case 2L. The winding shaft 13 is a winding shaft made of synthetic resin such as lightweight or flexible vinyl chloride or ABS, so that the twisting shaft is formed by the tension force generated when the network is expanded by using for a long time. It does not cause the movement, and smooth rotational movement can be performed, thereby reducing the operating force. By only releasing the hand from the drive handle 21 at the proper position, the drive handle 21 is instantaneously reversed by the elasticity of the compressed pressing spring 25 to be returned to its original shape, and at the same time connected to the latch 23. Since the interlocking shaft 2c slides downward by the pressing of the pressing spring 11 stored in the pocket 9a of the latch 9, the inner inclined surface of the front end jaw 9b of the latch 12 and the lever ( By strongly engaging the tip inclined surface 7d of 7a) and 7b, the levers 7a and 7b can be clamped to the locked upper and lower rail 32a and 33a to free the storage case 2c. It is possible to install the net 1 as desired by stopping and fixing it at the free position. At the same time, the latch 9 slides downward by sliding downward between the interlocking sections 2c, and the pressing force against the inclined surface 19c of the brake plate 19 of the inclined surface 9c of the latch 9 is released to remove the latch 9. The copper plate 19 is fed back by the pressing spring 20 and the rotation of the winding shaft 13 is constrained as the jaws 19a and the latch 12 of the brake plate 19 are engaged again. In order to return the storage case 2L which pulled the upper and lower frames 32 and 33 laterally in order to expand and install the net 1, the upper and lower rails are rotated by rotating the drive handle 21 again. When the clamping engagement of the levers 7a and 7b with respect to (32a) and 33a is released, the mantle 1R in the storage case 2L is wound by the force of the torsion spring 14 and the storage case is wound. 2L is to be returned. At this time, even if you inadvertently remove the hand from the drive handle 21, the interlocking movement (2c) is lowered by climbing to the rotation of the drive handle 21 in the original direction by the pressing spring 25, so the storage case 2L Since the levers 7a and 7b internally stored in the upper and lower lid briquettes 3 and 4 fixed to the upper and lower ends intervene the upper and lower rails 32a and 33a again, the storage case 2L suddenly stops. To prevent collision with the bell 34.

In the longitudinal roller screen, a lightweight and flexible synthetic resin winding shaft 13 allows the mesh roll 1R to be compactly wound in the storage case 2 in a compact cross section. Since the strength of the storage case 2 can be used as paper space enough, the storage performance of the narrow space is improved, and even if the wind pressure is applied to the expanded network 1, the upper and lower edges of the network 1 are opened. Interventions can be prevented from occurring, such as damaging the insect repellent. In addition, the left and right glass windows (35R) (35L) is pulled horizontally in the opening width of the whole open or enemy for ventilation, so that the storage case (2R) (2L) to the position to polymerize with the window frame 36R (36L) Can be further secured by the net (1) with the opening fully expanded by the stop fixing or by moving the window frame (36R) (36L) laterally and polymerizing with the storage case (2R) (2L). will be.

After the storage case 2L is pulled laterally to expand and install the net 1, the upper latch 9 is lowered, and the levers 7a and 7b clamp the upper and lower rails 32a and 33a to stop. 고정) At the same time, the latch 12 is constrained to the expansion direction of the mesh 1 by engagement with the jaw 19a of the braking plate 19, so that it is out-of-plane with respect to the mesh 1 for a long time. Even when an external pressure such as wind pressure in the direction is loaded, the mesh roll 1R is rotated again to prevent the mesh 1 from being expanded, and it is bent like a bow or the edge of the mesh 1 is separated from the upper frame rail 32a. It is effective to prevent the formation of gaps. And electric running on the same rail (33a) to the upper lid briquette (4) and lower lid briquette (3) in the state that the mesh (1) is expanded Even if one left and right glass window 35R is inadvertently slid laterally or collided, the upper and lower briquettes 4 and 3 can serve as stop waves. Is minute as in the cross slide will absorb its shock. Further, even when the storage case 2 and the winding shaft 13 are in the return direction, the winding shaft 13 in which rotation of the mesh 1 in the expansion direction is constrained by the above-described latch 12 is in the winding direction. Since the rotation is not constrained, it is possible to return the mesh 1 to which tension has been relaxed by the force of the torsion spring 14, so that the mesh 1 can always be kept in a tension state without sagging.

7 and 8, the present invention is elastically draped flat bar (44a), which allows the upper frame 43 opened in the second embodiment to expand and contract its opening by compression springs (45a, 45b) In the first embodiment, the take-up shaft 13 for winding and holding the mesh 1 to be pulled out is inserted by inserting the shaft 17 for mounting the torsion spring 14 in the first embodiment. Preferably, the upper lid briquette 28a of the lid briquettes 28a and 28b disposed in the upper and lower ends of the storage case 2L holding and holding the material made of synthetic resin such as lightweight, flexible vinyl chloride or ABS in a rotational manner. A roller 5 is installed in the upper roller briquette 40a so that the roller 39 can be rotated by abutting on the flat bar 44a. Compression clamps supporting the flat bar 44a as a solid hold Ring (45a) has a In a compression spring (45a) (45b) side than the elastic force of one spring (45a) arranged at the end side opening width of the opening arranged in the width center side is set weaker in (45b).

Since the vertical roller screen according to the second embodiment as described above has the above configuration, the shaft 17 inserted in the winding shaft 13 winding the net 1 by inadvertently being fixed to the storage case 2L. Even when the net 1 is suddenly returned by the elasticity of the torsion spring 14 mounted on the torsion spring 14, due to the elastic force directed downward of the compression springs 45a and 45b, the flat bar 44a is cast. The roller 39 in the upper lid briquette 28a and the door roller 5 in the lower lid briquette 28b are clamped to apply a braking action by frictional force, and in particular, the compression spring 45a disposed at the center of the opening width. Since the resilience force is set weaker than the compression spring 45a arranged at the side of the opening width end side, the clamping force in the vertical direction is increased as the storage case 2c is pulled back to the vertical frame 31 side and stored. Slowing down the acceleration of the return of the case 2c The selection of whether the storage case 2c is attached or returned to the vertical frame 31 by sudden stop or slow down at the same time as the down or sudden stop is performed. The compression spring 45a having the flat bar 44 draped in the opening upper frame 43 is selected. It is possible to carry out by adjusting the elastic force of 45b, and in particular, the suddenly stopped storage case 2c prevents a shocking return as it is pressed by hand to a predetermined position. Furthermore, the door car 5 is loaded with the elastic force of the compression springs 45a and 45b, which makes it possible to hold the above-described flat bar 44 on the opening top frame 43, and thus the storage case 2c and the mesh roll ( Since the load of 1R) is greater than that of the roller 39, the outer circumference of the wheel of the door car 5 is larger than the outer circumference of the roller 39, so that the sliding friction force of the door car 5 and the roller 39 is increased. Can be made almost equal, and since the storage case 2c is returned by the load equally divided by the net 1, the storage case 2c can be tilted and move, and can travel while holding the vertical.

8 is a separate embodiment of the vertical roller screen which is the second embodiment of the present invention. Specifically, the length of 5 to 10 cm is applied to the upper frame 43 close to the opening frame 31 for fixing the net length. The shaft 17 having the torsion spring 14 shown in the first embodiment therein in the opening gap, in which the flat bar 44 is fixed and the opening gap is slightly reduced as the opening gap is reduced. Upper and lower lid briquettes 28a and 28b fixedly disposed on the upper and lower ends of the storage case 22 for holding and winding the winding shaft 13 for winding and holding the mesh-shaped mesh 1 by winding out and inserting it. In the lower lid bracket 28b in the middle, the rollers held on the roller briquettes 40b while holding the door car 5 that supports the storage case 22 by traveling on the opening harness 43 are driven. (39) stand in the upper lid briquette (28a) After the roller 39 is fixedly held on the roller briquette 40a capable of rolling on the top frame 43 and the flat bar 44, the lower lid briquette is applied to these roller briquettes 40a and 40b. The interlocking rod 2c is connected to the upper end of the roller briquette 40b in the 28b, and at the tip of the interlocking rod 2c, which is connected and fixed to the roller briquette 40a in the lower lid briquette 28b. The flexible cushion spring 41 which is integrally mounted to the roller briquette 40a in the upper lid briquette 28a is connected.

Since the modified example of the second embodiment of the present invention has the configuration as described above, the storage case 2c is wound as the net 1 is wound up by the negative force of the torsion spring 14 inscribed in the winding shaft 13. And the roller 39 of the upper and lower sides are guided while compressing the cushion spring 41 between the openings reduced by the flat bar 44, so that the storage case 2L is subjected to the rotational friction of the upper and lower rollers 39. As a result of the braking action, sudden stop or slow down can be delayed without colliding with the bell 31. At this time, the operation selection of the slow down or sudden stop of the storage case 2L is performed by adjusting the force of the repulsion of the cushioning spring 41 and the force of the electric torsion spring 14 inscribed in the take-up shaft 13. In this case, the storage case 2L that is suddenly stopped in the middle may be pressed lightly by hand and closely adhered to the bell frame 31, so that the storage case 2L may be suddenly returned and collide with the bell frame 31.

Furthermore, the lower roller briquette 40b is removed and the lower end of the cushion spring 41 integrally mounted to the upper roller briquette 40a is supported on the bottom of the upper bracket 28a so that the door roller 5 and the upper roller ( 39) is a structure which is press-induced between the above-mentioned reduction opening gaps.

FIG. 9 is a synagogue side view of a vertical roll window provided on an indoor side of an opening of a free door or an opening / closing window which opens and closes only on one side. First, the storage case 2L has a net corner disposed at the door opening 26. The net 1 which is pulled laterally in the middle part of a frame is fully installed in an opening part. At this time, the lid briquettes 28a and 28b fixedly disposed on the upper and lower ends of the storage case 2L are guided and pulled horizontally to the upper and lower rails, and the net pressure hoop of one end of the mantle roll 1R described above ( 6) is press-fitted to the guide groove 31a of the bell frame 31, and the storage case 2L is pulled laterally to be detachably fixed to the bell frame 31 which is installed by using an engagement device (not shown). It was made by laying the network (1). However, when external pressure such as wind pressure is added to the net 1 in this state, the net 1 is tensioned in the out-of-plane direction and the winding shaft 13 is rotated in the direction of expanding the net 1 again. The entire wound and the remaining net is also expanded and the center portion of the net 1 is greatly inflated so that the upper and lower edges of the net are spaced apart from the upper and lower frames, thereby damaging the insect repellent action. Since the pulling force is applied to the double-sided adhesive tape and there is a closed end from which the retractable portion is separated from the take-up shaft 13, in this regard, as shown in the plan view of the third embodiment of FIG. The lid of the upper case of the storage case 2 is provided with a braking plate 27 which is detachably engaged with the latch 12 protruding from the upper end of the winding shaft 13 in the same shape as the shaft 17 and the winding shaft 13. It is internally stored in the briefing 28a slidingly, and it is stored. The teeth 2 are laterally pulled to secure the engagement to the embedding frame 31 and the reverse rotation of the take-up shaft 13 can be restrained.

That is, the braking plate 27 is disposed in parallel with the lid briquette 28a at the upper end of the storage case 2L, and the braking plate 27 is always shot with the pressing spring 29, and the jaw of the braking plate 27 27a) is detached from the retained 12 and the retained 12 is in a released state, so the flange head 27b of the brake plate 27 is released from the guide hole 28c of the lid briquette 28a. Protruding from the lid briquette 28a together with the storage case 2 and being compressed to the bell 31, the flange head 27b of the brake plate 27 is fixed to the bell 31. While impinging on the spring 30 and compressing the pressing spring 29, it is immersed in the guide hole 28c, and at the same time, the jaw 27a of the braking plate 27 is engaged with the latched 12 so that the winding shaft 13 Since the reverse rotation is prevented, the net 1 once drawn out from the take-up shaft 13 continues to be tense without sagging. Furthermore, the clearance error between the moving stole of the lid bracket 28a and the stroke required for engagement with the latch 12 is absorbed by the elastic force of the leaf spring 30, and the storage case 2 is provided. Even when the upper end portion is slightly slowed down and inclined, the jaw 27a of the braking plate 27 is securely engaged with the latched 12, and even if an out-of-plane direction load acts on the enlarged mesh 1 Since the shaft 13 is constrained in reverse rotation together with the retained 12, it is possible to prevent the mesh 1 from being greatly inflated and at the same time the longitudinal edge of the mesh 1 is pulled from the shaft winding shaft 13. The effect is to prevent the lung from being separated.

11 is an external view of a mesh-shaped mesh 1 made of, for example, a synthetic resin of polyester resin used in the first, second, and third embodiments described above, wherein the edge of the mesh is formed of a polyester hoop 28. It is reinforced. That is, as it is described above, the closer to the end of the mesh-like mesh 1, the closer to the free end, the closer the free end is, so that the reinforcement summation between the engaged and the transverse yarns is collapsed, so that the transverse elongation is increased. Acrylic or urethane-based coating agent to prevent elongation of the thread, even if the hardness of the thread is increased during use, and the edge part becomes single yarn, resulting in a bad appearance and a closed end which is simultaneously rolled up, and the winding shaft in a bent state It is wound in (13) and not only causes trouble in the light winding operation, but also leads to a gap in the expanded network 1 edge, which causes damage to the insect repellent effect.

Then, by depositing aluminum on both edges of the net 1 to finish, an ultra-thin polyester hoop (0.03 to 0.04 mm thick) 38 having a high tensile strength is attached to both sides of the net 1 with a width of 5 to 20 mm. The hoop 38 is integrally joined at both sides of the mesh width to reinforce the edge of the mesh, but the outer diameter of both ends of the mesh mirror 1R is thicker than the middle portion because the thickness of the mesh becomes thicker than the middle portion. The inner diameter of the storage case must also be largely molded, such as causing a problem in smooth rotational operation.

Therefore, the thickness of the net body 1 is determined by the outer diameter of engagement which is thicker than a horizontal thread. In general, the working is an extremely thin aggregate of polyester yarn, and has a round cross section of 0.3 to 0.4 mm as 55 to 75 denyl (thread thickness unit). Therefore, the above-mentioned polyester hoop 38 is bonded on both sides of the mesh, and the high pressure press is applied to press the flattened flattened flattened to fix the thickness of 0.25 ~ 0.29mm around the solidified shape by the adhesive force of the double-sided hoop. It is possible to prevent the restoration of the rounded linear shape, and by making the thickness of the reinforced network in this manner equal to or less than the thickness of the network edge of the other middle portion, the mesh roll 1R wound on the winding shaft 13 is entirely formed. It can be finished with a uniform outer diameter over, and smooth winding operation can be obtained in the storage case 2L.

In addition, even when the strongly installed net (1) is subjected to wind pressure, the edge of the net (1) with a strong tensile strength is not bent like a bow, it is in close contact with the vertical wall of the upper and lower rail rails have the effect of insect repellent action.

Furthermore, the purpose of mirror finishing by placing aluminum on both sides of the polyester tape 38 is to increase the density of the polyester dough surface to completely block aeration so that the guru applied to the hoop 38 contacts with air and moisture and ages. Not only can it be prevented, but also the effects of aging deterioration (aging) caused by radiant heat at cold temperatures and sun, infrared and ultraviolet rays can be reduced.

As described above, the vertical roll mesh screen of the present invention can operate the opening and closing of the screen according to the rotation operation of the driving handle, and when the rotation operation of the driving handle is canceled, the mesh screen is not wound up and momentarily firmly stopped and fixed. This prevents unnecessary expansion of the door, and improves the safety and durability of the door itself by relieving the opening and closing of the door, especially when it is returned, and also improves the reliability of the insect repellent action. The shock is relieved to increase the stability and durability of the mesh itself, and the edge of the mesh is reinforced with polyester hoops to prevent rewinding and bending and to significantly improve the durability of the mesh without disintegrating the mesh. It works.
