Description

Roll insect screen {ROLL MOSQUITO NET}

The present invention mainly relates to a roll screen that is installed on the window frame of a building to open and close, and more particularly to a roll screen that can block the lower gap when the screen is closed.

Insect screens are installed in the window frames of buildings and are mainly used to ventilate the outside while blocking the inflow of harmful insects such as mosquitoes and flies.

In the case of high-rise apartments and public buildings, roll screens are widely used to perform functions as insect screens without interfering with opening and closing windows, as most windows are made of casement windows or casement windows.

In general, the roll screen is a housing frame 200, the housing frame 200 of the housing frame 200 to accommodate the insect screen 100 wound on the winding rod 10 having a tension function as shown in the example shown in Figures 1 and 2 Guide frame 300 for guiding the screen 100 when lifting up and down on both sides, a handle bar 400 formed with a handle on the bottom of the screen 100, and a lower frame 500 coupled to the bottom of the guide frame 300 When the handle bar 400 is lowered to the lower frame 500 to be brought into contact with the lower frame 500, the screen is fixed by the fixing means, and the insect screen 100 is kept closed. The insect screen 100 is automatically opened by (10).

Here, in the closed state of the insect screen 100, the gap between the handlebar 400 and the lower frame 500 should be closely closed to prevent the invasion of mosquitoes, flies, bugs, etc. Infiltration can be prevented.

As such, a method for preventing the lower gap is conventionally made by coupling the mohair 420 to the bottom of the handle bar 400 as shown in FIGS. 1 and 2.

However, the mohair 420 is cut in the friction due to the opening and closing operation of the insect screen 100, because it is installed in the window frame because it is exposed to sunlight over many hours. The cut mohair is not good for health as it is broken and blown, and the conventional insect screen has a gap due to mohair that is worn out or has a small number of parameters.

Domestic Patent No. 10-1151334 “Spring tension control device of roll screen” Korean Patent Publication No. 10-2004-00074238

Accordingly, an object of the present invention is to provide a roll screen that can effectively prevent the closing gap of the screen without using the mohair used in the prior art.

According to the above object, the present invention, the housing frame 20 for receiving the insect repellent screen 10 wound on the winding rod, guide frame 30 for guiding the lifting screen 10 when lifting up and down on both sides of the housing frame 20 In the roll screen consisting of a handle bar 40 formed with a handle 40a at the bottom of the screen 10, and a lower frame 50 coupled to the bottom of the guide frame 30, The lower end of the handle bar 40 integral protrusion 42 is formed, the upper surface of the lower frame 50, the fitting fitting groove 52 that can accommodate the protrusion 42 of the handle bar 40 is customized It is configured to be formed, it is characterized in that it can effectively prevent the lower gap at the time of closing the insect screen without using the existing mohair.

The present invention is to prevent the gap between the handlebar and the lower frame in the roll screen screen, instead of the conventional structure of coupling the mohair to the lower handlebar, to prevent the gap by forming corresponding projections and fitting grooves on the lower and lower frame of the handlebar respectively. As a configuration so that the production is easy, the production cost is cheap, there is an advantage that can be used without changing semi-permanently.

Figure 4 is a perspective view of the main incision showing the configuration of the roll screen handle bar and the lower frame of the present invention in detail,
Figure 5 is a side cross-sectional view showing the operating state between the handlebar and the lower frame when opening and closing the roll screen of the present invention.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

Roll screen (A) according to an embodiment of the present invention is the housing frame 20 and the insect screen 10 to accommodate the insect screen 10 on the upper side as shown in Figure 3 the screen 10 up and down the housing frame 20 At the lower end of the guide frame 30 and the insect screen 10 to guide the lifting, a handle bar 40 having a handle 40a is provided to hold the handle bar 40 to lift and open the insect screen 10 and the handle bar 40. When lowered to the lower frame 50 so as to abut it is fixed by the fixing means, the insect screen 10 is maintained in a closed state, and when the release is fixed, the winding rod having a tension function built up in the housing frame 20 The screen 10 is automatically opened by the same as the operation of the conventional roll screen.

Particularly, it is preferable to use Korean Patent Registration No. 10-1151334, "Spring tension control device of a roll screen," which the inventors of the present application have a patent right.

On the other hand, the characteristic configuration of the present invention is to lower the handlebar 40 to open and close the insect screen 10 to the lower frame 50 to close the insect screen 10, the handlebar 40 and the lower frame by the damage of mohair, etc. (50) It has a structure that can be closely closed by preventing any gaps that may occur between them.

That is, referring to Figure 3 to 5, the bottom of the handle bar 40 coupled to the bottom of the insect screen 10 to open and close the insect screen 10 is formed with a protrusion 42 extending downward, integrally, the lower frame The upper surface of the 50, the fitting fitting groove 52 that can accommodate the protrusion 42 of the handle bar 40 is formed integrally correspondingly.

Figure 5 is a side cross-sectional view showing the operating state between the handlebar 40 and the lower frame 50 when opening and closing the insect screen 10 in the roll screen (A) of the present invention.

5 (a) shows the state before the handlebar 40 is completely lowered to the lower frame 50, (b) is the handlebar 40 is lowered down to the lower frame 50 is fixed screen 10 It shows the status of the function.

Referring to FIG. 5 (b), in the state in which the insect screen 10 is lowered to perform the function of the insect screen 10, the protrusion 42 of the lower portion of the handle bar 40 is fitted into the groove 52 of the lower frame 50. It is maintained in the image inserted in the) it is possible to closely close the gap between the handlebar 40 and the lower frame 50. That is, the protrusion 42 of the lower portion of the handlebar 40 is fitted with grooves 52 of the lower frame 50 so that the gap can be effectively prevented by convex and concave-convex coupling between each other. It is possible to prevent the intrusion of and also to prevent the infiltration of dust by the draft or draft.

In forming the lower protrusion part 42 of the handle bar 40, when the hollow wall plate body having the bottom side opening groove 44 is formed, the material cost can be reduced.

Handle bar 40 and the lower frame 50 is a widely used frame made of aluminum, each of the protruding portion 42 and the fitting groove 52 is formed in the form can be easily and inexpensive, and the existing mohair and As there is almost no deformation, it can be used semi-permanently. It also solves the problem of mohair being worn out and worn out over time.

In the present invention, the protrusion 42 is formed in the lower part of the handle bar 40 and the fitting groove 52 is formed in the upper surface of the lower frame 50. On the contrary, the fitting groove is formed in the lower surface of the handle bar 40 and the lower part is formed. Protrusions may be formed on top of the frame 50.

Reference numeral 46 is coupled to both ends of the handlebar 40 as a slider and fitted to the guide frame 40 so that the lifting and lowering of the handlebar 40 when opening and closing the insect screen 10 according to the operation of the handlebar 40. Make it smooth.

Although the foregoing description of the present invention has been described with reference to specific embodiments, various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention is not to be determined by the embodiments described, but should be determined by the scope of claims for utility model registration and the scope of claim for utility model registration.

The present invention is used in a roll screen.
