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 method, that is, sliding method like other windows of sliding doors, and is always installed outside the window, which is easy to be contaminated by dust, etc., and in such a case, the view right is impaired. Moreover, there is a problem in that the manufacturing cost and installation width of the window frame frame increases because a separate guide rail must be installed in the window frame frame for sliding the insect screen.

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.

An object of the present invention is to provide a roll screening device having improved convenience in installation work in a roll screening device for sliding windows that can be installed in a large sliding window and horizontally opened and closed.

In addition, another object of the present invention is to provide a roll screen screen device including a guide screen rail of the screen can be optimized, even when the screen is opened and closed horizontally, the rigid structure.

The roll screening device according to the present invention is a roll screening net main body, the screen is wound in a roll shape and is tensionably accommodated, a lead frame fixed to one end of the screen screen drawn out from the roll screening net main body, so that the lead frame is sliding A roll screening device including a guide rail and a lower rail, wherein the lower rail is attached to a guide formed on a sliding window frame frame in which the roll screen device is installed, and is spaced apart from the bottom of the window frame frame by a predetermined height.

Here, the roll screen screen main body, the roll screen screen case formed with a slit for drawing the screen screen; Winding pipe wound around the screen; A pair of rotating brackets fixed to both ends of the winding tube; A pair of case seals fitted at both ends of the roll screen case; And a spring interpolated in the winding tube, one end of which is fixed to one of the pair of case sealing ports and the other end of which is fixed to the winding tube.

In addition, the lower rail, the locking portion fitted to the one end; The flange portion extending outward along the longitudinal direction of the lower rail; is closed by the formed rail encapsulation.

In addition, upper and lower pipe portions are formed at upper and lower portions of the insect screen, respectively, and each of the upper rail and the lower rail includes: a slit portion for guiding the lead frame to slide; And a guide rod inserted into the upper tube portion or the lower tube portion when the insect screen is drawn along the lead frame. Here, the rail encapsulation may be formed integrally with the guide rod.

The roll screen device according to the present invention, can be installed in a large sliding window and can also be opened and closed horizontally. In addition, even when the screen is opened and closed horizontally, it is possible to optimize the sealed state of the top and bottom of the screen. Compared to the conventional roll screening device, the screen guide structure of the relatively rigid structure is adopted, so there is a better effect on the prevention of safety accidents. Furthermore, since the lower rail is spaced apart from the bottom surface of the window frame frame, it is advantageous for drainage of rain water or the like accumulated on the window frame frame, and further, the operation of fixing the lower rail to the guide of the window frame frame becomes easy.

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

First, referring to Figure 1, the roll screening device according to the present invention is configured to be installed on the sliding window. First, a description of 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), and the 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. The roll 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 on 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 insect screen device 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 winding tube 10 by a fixing protrusion 62a formed on the spring fixing member 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 by a pair of case sealing openings (40, 50).

On the other hand, the other end of the insect screen 110 wound on the winding pipe 10 is drawn out through the slit 120b formed in the case 120a is fixed to the lead frame 140. The insect screen 110 installed in this way may be wound or tensioned according to the sliding operation of the lead frame. In particular, the insect repellent screen 110 is in the wound state by the spring 60, when the lead frame 140 is slid accordingly after sliding, and can be elastically returned when the lock state of the opening and closing device 100 is released. 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. The fixing plate 116 is formed at one end of the insect screen 110, the fixing plate 116 is inserted into the fixing groove 11 formed in the winding pipe 10 is fixed. 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 the inner diameter of the winding tube 10, and one end of the spring 60 is inserted into the groove 15 by inserting a fixing protrusion 62a formed in the spring fixture 62. 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. 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. The pipe parts 112 and 114 have larger thickness than the insect net, so the insect screen is wound up. When wound in the tube 10, it takes up a large volume of state. Therefore, 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, the space to be installed in the window frame frame 300 is insufficient, so the case 120a should be minimized as much as possible. Accordingly, the pipe storage units 20b and 30b of the pivot brackets 20 and 30 facilitate the winding and tensioning operation of the insect screen having the pipe parts 112 and 114 employed in the present invention, and at the same time the volume of the case 120a. To minimize this. 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 may be fitted into 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 rod are illustrated. The relationship of the earth 186 is the same. In addition, FIG. 6 is for explaining a 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 163 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. Therefore, when the roll screen is fully pulled out and functions as a screen, the upper and lower portions of the screen 110 are completely closed by the upper and lower 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 screening device, both ends of the screening screen are simply fitted to the rail, but when the screen is configured to be opened and closed horizontally with this structure, the children fall against the screening screen and the risk of falling due to the screening screen is released. have. However, the upper rail and lower rail structure adopted in the present invention has the effect of preventing such a safety accident.

Next, the roll screen device according to the present invention is installed on the outdoor side of the window frame frame 300, Figure 8 shows the roll screen screen device according to the present invention is installed on the window frame frame 300. As shown in FIG. 8, the roll screen case 120a is installed at a side edge of the window frame frame 300 (for reference, in FIG. 2, it is shown as being installed on the left side when viewed outdoors, and in FIG. 8, when viewed from the outside, the right side is installed. Shows the installed state). In addition, the upper rail 160 and the lower rail 180 are attached to the outdoor guide (or guide rail) 300a of the window frame frame 300. In particular, it should be noted that the lower rail 180 is attached to the outdoor side guide 300a, but is formed to be spaced apart from the bottom surface 300b of the window frame frame 300 at a predetermined interval and high.

In the present invention, the reason why the lower rail 180 is installed to be spaced apart from the bottom surface 300b of the window frame frame 300 is as follows. First, the position where the roll screen device of the present invention is installed is the outdoor space of the window frame frame 300, as shown in Figure 2 is formed in the space between the plurality of guides. Rain space may accumulate in the space between the guide rails on which the roll screen device is installed. If the lower rail 180 is connected to the bottom surface 300b, drainage of the rainwater may not be easy, and the cumbersomeness of cleaning may be increased. Can be. Second, since the roll screen device according to the present invention is installed between a plurality of guides, the installation space is not enough. In particular, in the case of the lower rail 180, it must be attached to the guide 300a. If the screw hole is formed on the bottom surface 300b, rainwater enters the window frame frame 300 through the formed screw hole. Done.

Therefore, in the present invention, the lower rail 180 is attached to the guide 300a to be spaced apart from the bottom surface 300b of the window frame frame 300, but provides a means for securing convenience of work. 9 illustrates a structure of a rail sealing portion 186 for closing one end of the lower rail 180. As shown in FIG. 9, the rail encapsulation 186 of the present invention includes a locking portion 186a fitted to one end of the lower rail 180, and a flange portion extending outward along a length direction of the lower rail 180. 186b) is formed. Further, optionally, the rail encapsulation 186 may be formed integrally with the guide rod 184, in which case the lower rail similar to the upper rail 160 and the upper leadframe encapsulation 142 described in FIG. The guide rod 184 may be supported by the lead frame encapsulation 144 so that the fastening structure in which the guide rod 184 is inserted into the lower tube portion 114 may be applied. In addition, the through hole 186c may be formed in the flange portion 186b.

As shown in FIG. 9, a flange portion 186b extends in the longitudinal direction of the lower rail 180 in the rail sealing hole 186 fitted to the lower rail 180 and closing one end thereof. Therefore, the lower rail 180 is fixed to the guide 300a of the window frame frame 300 through the flange portion 186b. 8 again, since the lower rail 180 is fastened to the guide 300a through the flange portion 186b, the fixing operation is much easier. In addition, the drain 300d may be formed in the guide 300a of the window frame frame 300 under the lower rail 180, and thus rainwater may be drained through the drain 300d.
