Description

Double open type roll screen of project windows

The present invention relates to a double-open roll insect screen for a project window, and more specifically, a single insect screen is configured so that it is possible to select and use not only pest blocking but also fine dust blocking, to increase durability, and to facilitate locking and unlocking when selecting an insect screen It relates to a double-opening roll insect screen for a project window that has increased usability.

In general, insect screens are installed on windows of residential facilities or buildings to prevent intrusion of pests.

These insect screens are usually installed in the form of a simple mesh-like mesh made of a metal mesh or plastic mesh.

However, in the mesh-type insect screen, fine dust or yellow sand is inevitably introduced into the room as it is.

Such fine dust or yellow dust has recently emerged as a serious environmental problem, and in particular, fine dust penetrates deeply into the human alveoli and is a direct cause of various respiratory diseases, as well as lowering the immune function, leading to various diseases. It requires very careful attention.

Therefore, the influx of allergens such as vehicle smoke in an environment with frequent vehicle driving, fine dust, yellow dust, and seasonal pollen cannot be blocked by insect screens, and in this case, the window must be closed.

In order to solve this problem, recently, a fine dust blocking network called a 'nano network' has been released to replace the existing insect screen.

However, since these fine dust blocking nets are equipped with both insect repellent and fine dust blocking functions that have completely replaced insect screens, they are of a fixed type, so they have excellent fine dust blocking functions due to their compactness, but have a drawback in that visibility is sharply reduced.

In addition, windows are opened for ventilation on a sunny day without fine dust or yellow dust. Nevertheless, there are disadvantages that ventilation is not performed properly because the nano-net is too dense, the view is not too good, and the room is darkened. There are also disadvantages.

For this reason, it is inevitably necessary to completely open the fine dust shielding net for ventilation or view, so at this time, there is a disadvantage that the insect repellent function is weakened.

As another example, a method of installing a roll screen with the existing screen as it is and pulling it up and down to block it separately is also disclosed. Therefore, it has the disadvantage of being cumbersome to use.

In this regard, in the following [Prior Art Literature], a fine mesh and an insect screen are installed together, such as Patent No. 10-1871766 (June 21, 2018) 'Roll-type insect screen with dust-proof function' A technology that can be used as a network has been disclosed.

However, in the case of the registered patent, the second blocking rod spread out in the process of attaching and detaching the first fixing means to hook the second blocking rod provided in the second extension rod may be easily broken, and the fixing performance due to the decrease in elasticity There is a disadvantage in that durability is lowered, such as falling.

In addition, in order to use the insect screen and the fine net alone or half and half, a magnet with strong magnetic force is used when fixing each other. There are also disadvantages of being large.

According to the present invention, it is possible to obtain the effect of increasing the convenience in use by increasing the durability and facilitating locking and unlocking when selecting the insect screen, as well as blocking pests and fine dust with one insect screen.

1 is an exemplary view of a roll insect screen according to the present invention.
2 to 4 are exemplary enlarged views showing the main part of FIG. 1 .
5 is an exemplary perspective view showing a part of the roll insect screen according to the present invention cut away.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 and 2, the roll insect screen according to the present invention is a double-open insect screen applied to the project window.

At this time, the project window refers to a window having a structure that is opened by pushing the hinge on the upper side, and the roll screen of the present invention is applied to this window, and the roll screen is configured to open and close on both sides.

The roll insect screen according to the present invention includes a general net roll housing 100 and a fine net roll housing 200 .

At this time, the general mesh roll housing 100 has a built-in general insect screen wound in a self-winding manner, so that when there is no external force, it automatically winds and maintains the state drawn into the general network roll housing 100 .

Similarly, the fine dust net is embedded in the fine mesh roll housing 200 while being wound in a winding manner, so that when there is no external force, the fine dust net is automatically wound while maintaining the state drawn into the fine mesh roll housing 200 .

In addition, both ends of the general net roll housing 100 and the fine net roll housing 200 are connected by a pair of roll guides 300 .

In this case, a slit (reference numeral omitted) is formed on the opposite surface of the roll guide 300 , so that each general insect screen or fine dust net drawn from the general mesh roll housing 100 or the fine mesh roll housing 200 . Both ends of the are to slide safely along the slit.

In addition, both ends of the general net traction piece 110 and the fine net traction piece 210 are fitted to the roll guide 300 to slide, respectively, and one end of the general insect screen is fixed to the end of the general net traction piece 110, One end of the fine dust net is fixed to the end of the fine net traction piece 210 .

Therefore, when the general net traction piece 110 and the fine net traction piece 210 are completely fixed in close contact with the general network roll housing 100, at this time, the function of the fine dust net is performed. When the 210 is completely fixed in close contact with the fine mesh roll housing 200, at this time, the general insect screen function is performed, and the general mesh traction piece 110 and the fine mesh traction piece 210 are maintained in a locked state at the center of the length. Half of the normal insect screen and half of the fine dust network, that is, half of the functions will be performed.

In addition, when the general net traction piece 110 is fixed in close contact with the general network roll housing 100 side, and the fine net traction piece 210 is closely fixed to the fine net roll housing 200 side, it is completely open as a state without an insect screen, and a large amount of It can be used to ventilate the air.

On the other hand, a locking unit 400 capable of locking or releasing each other is installed in the middle of the length of the general net traction piece 110 and the fine net traction piece 210 .

The locking unit 400 is divided into a normal mesh-side locker part GL and a fine mesh-side locker part ML based on the locking boundary, as in the examples of FIGS. 2 to 5 .

At this time, the general mesh side locker part (GL) is fixed to the upper surface of one end of the general mesh traction piece 110 and has an inclined surface at one side and a loosening guide 120 having a protruding inclined protrusion 122, and the inclined protrusion 122 ) is formed on the magnet piece 124 fixed to one side of the loosening guide 120, the first fixing block BL1 in which the loosening guide 120 is built, and the first fixing block BL1. A general mesh hook fixing piece 150 that is inserted and assembled to move up and down within a certain width, and one end is hook-coupled to the fixing hook 102 (see FIG. 1) of the general mesh roll housing 100 in a one-point fixed manner, and the general network It is installed on the lower part of the hook fixing piece 150 and includes a fixing piece spring 140 to provide an elastic return force.

Therefore, when you want to release the hook coupling, if you press the general mesh hook fixing piece 150, the fixing piece spring 140 is pressed and the hook coupling portion is easily released. ) can be easily separated from

This is different from the method in which the hook piece is elastically deformed in the prior art to release the hook coupling, and is operated by pressing and releasing the spring, so there is no risk of damage to the hook piece and thus a longer life is possible. In particular, in the present invention, the fixing hook 102 is also configured to be replaceable only for that part, so that in case of any damage, the maintenance cost is also low because only the fixing hook 102 needs to be replaced with a single unit without replacing the entire roll housing.

And, when the hook is coupled, simply push it in, the fixed piece spring 140 is pressed and elastically deformed to be easily coupled.

In addition, the general mesh hook fixing piece 150 is not easily separated and separated because it is fitted in the first fixing block BL1 that is bolted to the general mesh traction piece 110 . In this case, the structure in which the general mesh hook fixing piece 150 is movably assembled to the first fixing block BL1 is such that the fine mesh hook fixing piece 250 to be described later is movable to the second fixing block BL2. Since it is the same as the assembled structure, it will be replaced by explaining it.

In addition, the fine mesh side rocker part (ML) has a spring 220 for loosening disposed on one end of the upper surface of the fine mesh traction piece 210, and one side disposed on the top of the spring for loosening 220 is open, and the inclined protrusion 122 ) and a magnet housing 230 that can be moved, is built into the magnet housing 230 and fixed with a set screw 232 , and is adsorbed by magnetic force with the magnet piece 124 through the opening of the magnet housing 230 . It includes a fixing magnet 240 that can be, and a fine mesh hook fixing piece 250 disposed on the upper end of the loosening spring 220 and fixed to the lower side of one side of the magnet housing 230 by a fixing bolt 252. do.

At this time, the end of the fine mesh hook fixing piece 250 also has a structure that can be hooked up like the general mesh hook fixing piece 150, and the fixing hook 202 provided in the fine mesh roll housing 200 (see FIG. 2). It is configured so that it can be fixed by hanging on the one-point method.

In addition, since the fine mesh hook fixing piece 250 is also fitted and fixed on the second fixing block BL2 bolted to the fine mesh pulling piece 210, the entire fine mesh side locker part ML is not separated.

That is, as shown in FIG. 5 , fitting protrusions DT protrude from both sides of the body of the fine mesh hook fixing piece 250 , and the fitting protrusions DT are of the insertion groove GO of the second fixing block BL2. It is fitted in the protrusion fitting grooves (HV) formed on the inner walls of both sides and is installed to be movable up and down within a certain width while being restrained not to be separated from the upper part.

Accordingly, when the normal mesh side locker part GL and the fine mesh side locker part ML are attached to each other by magnetic force, the user presses the upper surface of the magnet housing 230 to release it.

Then, the entire micro-mesh-side rocker part ML is lowered, and in the process, a portion of the lower end of the magnet housing 230 is inclined to ride on the inclined protrusion 122 of the loosening guide 120 .

Therefore, as in the example of FIG. 4 , as the separation angle increases along the central axis, the fixing force between the magnet pieces 124 and the stationary magnet 240 attached to each other is easily released.

That is, it can be easily separated without applying a great force.

As such, the double-opening roll insect screen of the project window according to the present invention has the advantage of maximizing user convenience.
