Roll-type Insect Net Apparatus for a Sliding Door}

The present invention relates to a roll screen device for sliding windows and doors that can be installed in sliding windows that open and close horizontally.

Insect screens are usually installed outside the windows of buildings to prevent pests from entering the room. Insect screen is installed on the outermost side of the windows, usually in sliding doors are installed by combining the insect screen in the frame for sliding screens on a separate guide rail formed in the window frame frame.

Such a conventional insect screen is opened and closed in a sliding way, that is, sliding like other windows of sliding windows, and is always installed outside the window, which is easily contaminated by dust, etc., and in such a case, the view right is hindered. Since a separate guide rail must be installed in the window frame frame for sliding of the insect screen, there is a problem that the manufacturing cost and installation width of the window frame frame increases.

In order to solve this problem, a roll screen net has been recently developed in which a screen is wound in a roll form and is installed in a tensionable manner. However, the roll screens used to date are limited only when the size of the comparative window is small, and are difficult to use for large sliding windows such as an apartment veranda. In addition, the conventional roll screen has a form that can be opened and closed vertically, the roll screen that can be opened and closed horizontally in sliding windows installed on the veranda has not been developed yet.

As such, one of the reasons why a horizontal roll screen device, which can be installed to be opened and closed horizontally on a large window, that is, a sliding window installed in an apartment veranda, is not developed. It is not possible to bury the installation inside the window frame frame, another reason is that it is difficult to seal the top and bottom of the screen when the screen is opened and closed horizontally. In particular, in order to achieve the original purpose of the insect screen, it is necessary to maintain the closed structure so that the insect pests can not penetrate while opening and closing the insect screen horizontally.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of a roll screening apparatus according to the present invention.

First, referring to Figure 1, the roll screening device according to the present invention is configured to be installed in a sliding window. First, when explaining the configuration of a general sliding window, when viewed from the outside of the building, for example, the window frame frame 300 is installed in the opening (not shown) of the concrete building, the window frame frame 300 is a predetermined guide rail (not shown) C) is formed, and inner and outer windows 220 and 210 are fitted to slide along the guide rail. In particular, the outer window 210 installed outside the building is composed of a window frame 212 and a glass window 214 installed there. Roll screen screen device according to the present invention is installed to be opened and closed in conjunction with the outer window frame 212, the roll screen screen body 120 is installed on the inner side (between a plurality of guide rails) of the window frame frame (300). In addition, the insect screen 110 wound on the roll screen body 120 is guided along the upper and lower rails (160, 180) and is tensioned by the lead frame 140, the lead frame 140 is a predetermined opening and closing device ( It is installed to be fixed and dismantled to the window frame 212 through the 100, 200. Insect screen 110, the roll screen main body 120, the upper and lower rails (160, 180), the lead frame 140 constituting the roll screen screen device according to the present invention are all a plurality of guide rails formed in the window frame frame 300 Among them, it is installed in a predetermined space between the guide rails for guiding the outer window frame 212, and is installed to open and close the insect screen according to the opening and closing of the outer window (210).

Referring to Figure 2, when explaining the configuration of the roll screening apparatus according to the present invention. First, tubular upper and lower tubular portions 112 and 114 are formed on the upper side and the lower side of the insect screen 110. One end of the insect screen is fixed to the take-up pipe 10 and the other end is fixed to the lead frame 140. Rotating brackets 20 and 30 are respectively fixed to both ends of the winding tube 10. Then, the spring 60 is inserted through the pair of rotating brackets 20 and 30 and the winding tube. One end of the spring 60 is fixed to any one of the pair of case sealing openings 40 and 50, and the other end of the spring 60 is fixed to the take-up pipe 10 through the spring holding device 62. In addition, the winding pipe 10 wound around the screen 110 is mounted in the roll screen screen case 120a in a state in which the spring 60 is installed together with the rotation brackets 20 and 30. Then, both ends of the roll screen case (120a) is closed through a pair of case openings (40, 50).

On the other hand, one end of the insect screen 110 wound on the winding pipe 10 is drawn out through the slit 120b formed in the case (120a) and one end is fixed to the lead frame 140. The insect screen 110 installed as described above may be wound or drawn out according to the sliding operation of the lead frame. In particular, the insect repellent screen 110 is in a wound state by the spring 60, and when the lead frame 140 is slid out, and accordingly, after the lock state of the opening and closing device 100 is released, it may be elastically returned. In addition, the upper tube portion 112 of the insect screen 110 is drawn into the upper rail 160 as the lead frame 140 is sliding, wherein the guide rod 164 is configured to be inserted into the upper tube portion 112. In this case, a slit 162 is formed in the upper rail 160, and the lead frame sealing hole 142 is movable along the slit 162. The lead frame encapsulation 142 is for finishing one end of the lead frame 140, and at the same time supports the guide rod 164 so that the upper tube 112 is inserted into the guide rod 164. Similarly, the coupling relationship between the lower pipe part 114, the lead frame sealing hole 144, the lower rail 180 and the guide rod 184 is the same.

Next, with reference to Figure 3, the coupling relationship of the rotation bracket (20, 30), the winding pipe 10, the insect screen 110 will be described. A fixing plate 116 is formed at one end of the insect screen 110, and the fixing plate 116 is inserted into and fixed to the fixing groove 11 formed in the winding pipe 10. In addition, a plurality of grooves 13 are formed in the outer diameter of the winding tube 10, and the pivoting bracket 20 is fixed to the winding tube 10 by fitting the fixing protrusion 20c into the groove 13. . In addition, a groove 15 is formed in an inner diameter of the winding tube 10, and one end of the spring 60 is wound by inserting a fixing protrusion 62a formed in the spring fixture 62 into the groove 15. It can be fixed to (10).

On the other hand, the pipe bracket 20b is formed in the rotation bracket 20, and the outer diameter of the pipe receiving portion 20b is formed smaller than the outer diameter of the take-up pipe 10. In the state in which the insect screen 110 is wound, as shown in Figure 4, the upper tube portion 112 is received while being wound in the tube portion storage portion 20b of the rotation bracket 20. As will be described later, in the present invention, the pipe parts 112 and 114 are formed in the insect screen 110 to achieve a structure that can be sealed even when the insect screen is tensioned, but the pipe parts 112 and 114 have a larger thickness than the insect net. When the insect screen is wound in the take-up pipe (10) will occupy a large volume of state. In order to prevent malfunctions when the winding and pulling operations of the insect screen 110 are repeated, the case 120a should be made sufficiently large. However, if the volume of the case 120a is large, since the space to be installed in the window frame frame 300 is insufficient, the case 120a should be bulky. The pipe storage portions 20b and 30b of the rotation brackets 20 and 30 facilitate the winding and tensioning operation of the insect screen in which the pipe portions 112 and 114 employed in the present invention are formed, and at the same time increase the volume of the case 120a. It is to minimize. In FIG. 4, a state in which the upper pipe part 112 of the insect screen is wound and accommodated in the upper pivot bracket 20 is schematically illustrated. As shown in FIG. 4, even when the upper pipe part 112 is formed, it can be expected that the insect screen 110 can be wound to a substantially constant outer diameter without being convex in the upper part of the insect screen.

Next, referring to FIG. 5, a rotation groove 54, a bracket support shaft 56, and a spring fixture 58 are formed inside the case encapsulation member 50. In FIG. 2, the spring 60 is fixed to the upper case encapsulation 40, but those skilled in the art can understand that the two case encapsulations 40 and 50 are symmetrical to each other, and thus, the lower case encapsulation ( 50) and the lower pivot bracket 30, but the upper case sealing opening 40 and the upper pivot bracket 20 may be configured in the same structure.

The pivoting plate 30a of the pivoting bracket 30 is fitted to the bracket support shaft 56 and then seated in the pivoting groove 54. Therefore, when the insect screen 110 is wound and tensioned, the rotation bracket 30 can be safely rotated without being caught. In addition, one end of the spring 60 is fitted and fixed to the spring fixture 58.

Next, referring to FIG. 6, the lead frame sealing opening 142 includes a body 142 a fitted to one end of the lead frame 140 and a slit insertion inserted into the slit 162 formed on the upper rail 160. It consists of a piece 142b and the guide rod guide 142c which was interpolated to the upper rail 160, and the one end of the upper pipe | tube part 112 was fixed. Here, the guide rod guide 142c supports the guide rod 164 such that the guide rod 164 is inserted into the upper pipe portion 112 when the insect screen 110 is drawn out along the lead frame 140. In addition, one end of the upper rail 160 is fitted with a rail seal 166 is closed, the rail seal 166 may be formed integrally with the guide rod 164. In FIG. 6, the upper rail 160, the upper leadframe encapsulation 142, and the upper rail encapsulation 166 are illustrated as an example, but the lower rail 180, the lower leadframe encapsulation 144, and the lower rail encapsulation are illustrated in FIG. 6. The relationship of (186) is the same. In addition, FIG. 6 is a diagram illustrating the coupling relationship between the upper lead frame sealing opening 142, the upper pipe section 112 of the insect screen, and the rail sealing opening 166 in which the guide rod 164 is integrally formed. The components are all mounted inside the upper rail 160 (dotted line).

Referring to Figure 6, when explaining the coupling relationship when the insect screen 110 is wound along the lead frame 140, the guide rod guide of the lead frame sealing member 142 fixed to one end of the lead frame 140 The upper tube part 112 of the insect screen 110 is fixed to 142c. The guide rod 164 is seated on and supported by the guide rod guide 142c. When the insect repellent screen 110 is completely wound on the case 120a, only a portion of the end of the guide rod 164 may be inserted into the upper tube portion 112 while being supported by the guide rod guide 142c. When the insect repellent screen 110 is drawn out according to the sliding operation of the lead frame 140, the slit inserting piece 142b moves in a state of being fitted into the slit 162 formed on the upper rail 160. At this time, the upper tube portion 112 fixed to the guide rod guide 142c is also drawn out along the lead frame 140, and at the same time the guide rod 164 supported by the guide rod guide 142c is the upper tube portion ( Interpolated at 112).

In the state where the insect screen 110 is completely drawn out, as shown in FIG. 7, the upper pipe part 112 of the insect screen 110 is fitted into the guide rod 164 in the upper rail 160. Similarly, the lower pipe part 114 of the insect screen 110 is fitted to the guide rod 184 even inside the lower rail 180. Thus, when the roll screen is fully pulled out and functions as the screen, the top and bottom of the screen 110 are completely closed by the top and bottom rails 160 and 180, respectively. In particular, when the diameter T2 of the guide rod 164 is larger than the opening width T1 of the slit 162, a relatively strong coupling force is maintained so as not to be separated from the upper rail 160 even when the insect screen 110 is pulled down. Can provide. In the conventional vertical roll screen device, both ends of the screen screen are simply inserted into the rail. However, when the screen screen is configured to be opened and closed horizontally, children may lean against the screen and fall off the screen. . However, the upper rail and lower rail structure adopted in the present invention has the effect of preventing such a safety accident.

Although a preferred embodiment of the present invention has been described so far, those skilled in the art will be able to implement in a modified form without departing from the essential characteristics of the present invention. Therefore, the embodiments of the present invention described herein are to be considered in descriptive sense only and not for purposes of limitation, and the scope of the present invention is shown in the appended claims rather than the foregoing description, and all differences within the equivalent scope of the present invention Should be interpreted as being included in.
