Therefore, specially defined terms may vary according to the intention or custom of users and operators, and definitions of these terms should be determined based on the contents throughout the present specification.

First, the configuration of the insect-proof cap installed in the drain hole of the window frame frame according to the present invention is installed from the inner cap 100 installed in the inside of the drain hole 321 formed in the screen rail 320, and the outside of the drain hole 321 It can be broadly divided into an outer cap 200 coupled to the inner cap 100, and each component will be described in more detail as follows.

First, the inner cap 100,

As shown in FIG. 1, rainwater accumulated in the window frame 300 is installed directly behind the drain hole 321 of the screen rail 320 between the window rail 310 of the window frame 300 and the screen rail 320 It guides them to be discharged to the outside through the air, and prevents pests from entering the room through the drain hole.

A preferred embodiment of the inner cap 100 will be described in detail through FIGS. 2 and 3.

The inner cap 100 is composed of a hexahedral enclosure 110 having a space 111 of a predetermined size therein while the bottom surface is opened, and as it is located between the window rail 310 and the screen rail 320 (110) may be a rectangular parallelepiped shape having a long length and a short width.

As the enclosure 110 is positioned directly behind the drain hole 321 formed in the screen rail 320, an opening 112 of a predetermined size is formed in the front of the enclosure 110 so as to communicate with the drain hole 321 .

The opening 112 may be formed on the rear side together with the front of the housing 110, and when both the opening 112 are formed in the front and rear of the housing 110, the housing 110 is connected to the window rail 310 In the process of installing between the screen rails 320, there is no need to consider the front and rear directions of the enclosure 110 in which the opening 112 is formed, so that the enclosure 110 is formed between the window rail 310 and the screen rail 320. When installed, the drain hole 321 and the opening 112 do not coincide with each other, so that inconvenience such as re-installation can be prevented in advance.

A plurality of through holes 113 are formed on both sides and upper surfaces of the enclosure 110, and the size of the through holes 113 is configured to allow rainwater to pass through without pests, and through holes according to design conditions. When 113 is formed in a size that allows small pests to pass through, a locking member may be formed in the through hole 113 in the form of a straight line or a grid to prevent the inflow of pests.

The number, arrangement, and location of the through holes 113 formed in the enclosure 110 need not be determined in any one form, and in consideration of the moving direction and amount of rainwater moving within the window frame frame 300, etc. Various modifications can be implemented.

Both sides of the enclosure 110 may be preferably formed to be inclined, and when the through hole 113 is formed on the side in an inclined state, the contact area with rainwater moving to both sides of the enclosure 110, etc., is increased. While a large amount of rainwater can be smoothly passed through the through hole 113, and when installing by inserting the enclosure 110 between the window rail 310 and the screen rail 320, the amount of the enclosure 110 As the external force is applied by gripping the side, the external force can be accurately and effectively transmitted to both sides of the enclosure 110 that is formed to be inclined.

In addition, both sides of the enclosure 110 are parts that are gripped by the user's hand when the inner cap 100 is installed or removed, so a plurality of non-slip protrusions 115 forming a straight line in the width direction on both sides of the enclosure 110 ) May be formed.

When the non-slip protrusions 115 are formed on both sides of the housing 110, through holes 113 formed on both sides of the housing 110 may be formed between the non-slip protrusions 115, and the non-slip protrusions It may be formed while being over (115).

On the other hand, the inner cap 100 may be installed in the drain hole 321 while being combined with the outer cap 200 to be described in detail later to form an insect repellent cap, but only the inner cap 100 ′ without the use of the outer cap 200 Insect repellent cap may be configured.

When only the inner cap 100' is installed in the drain hole 321 without the use of the outer cap 200 to form an insect repellent cap, the inner cap 100' located between the window rail 310 and the screen rail 320 is When unnecessarily moved, the opening 112 formed in the enclosure 110 of the inner cap 100' cannot communicate with the drainage hole 321 of the screen rail 320, such as rainwater flowing into the interior of the window frame 300 Since drainage may not be possible through the drain hole 321, the inner cap 100 ′ installed between the window rail 310 and the screen rail 320 needs to be prevented from unnecessary movement.

Accordingly, as an embodiment for preventing unnecessary movement of the inner cap 100', the longitudinal front or longitudinal rear of the enclosure 110, or both the longitudinal front and rear, the window rail 310 and the screen rail 320 ) By forming a curved portion to protrude toward the inner surface of the enclosure 110, the inner surface of the window rail 310 or the inner surface of the screen rail 320 or the inner surface of the window rail 310 and the screen rail 320 Unnecessary flow can be prevented by being combined by force fitting.

In addition, another embodiment for preventing unnecessary movement of the inner cap 100 ′ is to prevent movement protruding forward on both upper sides of the inner circumference of the opening 112 of the enclosure 110 as illustrated in FIGS. 4 and 5 Protrusion 114 can be formed, and when the housing 110 is installed between the window rail 310 and the screen rail 320, the movement preventing protrusion 114 is formed around the inside circumference of the drain hole 321 of the screen rail 320 It is also possible to prevent unnecessary movement of the housing 110 installed between the window rail 310 and the screen rail 320 as it is caught in a state.

Here, when the movement preventing protrusion 114 excessively protrudes from the inner circumference of the opening 112 of the enclosure 110, the movement preventing protrusion in the process of inserting the enclosure 110 between the window rail 310 and the screen rail 320 Since (114) causes unnecessary interference with the inner surface of the screen rail (320), it is preferable to protrude appropriately in the elastic range, and by configuring the bottom surface of the movement preventing protrusion (114) to be inclined, the movement preventing protrusion (114) is the screen rail ( It is also desirable to configure to move smoothly along the inner surface of 320).

In addition, in order to prevent unnecessary movement of the housing 110, the movement preventing protrusion 114 may be formed together in the curved shape of the housing 110 described above, so that unnecessary movement of the housing 110 may be prevented more effectively.

The outer cap 200,

As shown in Figure 2, the above-described inner cap 100 is installed in front of the drain hole 321 formed in the screen rail 320 and is installed at the rear of the drain hole 321 between the window rail 310 and the screen rail 320 Is combined with

A preferred embodiment of the outer cap 200 will be described in detail through FIGS. 3 and 6.

The outer cap 200 is formed with holes 211 having a shape and size corresponding to the drain hole 321 in the center of the front of the body 210, and forming a right angle with respect to the rear surface on both sides of the body 210 A pair of locking pieces 213 protruding in length are formed, and these locking pieces 213 are fitted into the drain holes 321.

The hole 211 formed in the front center of the body 210 may form a water film due to the surface tension when rainwater discharged through the drain hole 321 moves, and this water film reduces the functionality of drainage. Accordingly, it is necessary to prevent a water film from being formed in the hole 211, and for this purpose, at least one water film preventing protrusion 212 protruding toward the center may be formed around the inner circumference of the hole 211.

As illustrated in FIG. 7, the facing distance between both locking pieces 213 formed on the rear surface of the body 210 may be configured as a distance corresponding to the lengthwise distance of the drain hole 321, and both locking pieces 213 A first protrusion (214a) is formed at a point spaced a predetermined distance from the rear surface of the body 210 on the outer surface along the longitudinal direction of the body 210, and the locking portion 214 is formed between the rear surface of the body 210 and the first protrusion 214a. ) Is formed, and a second protrusion 215a is formed at a point spaced apart from the first protrusion 214a by a predetermined distance, so that a fitting portion 215 is formed between the first protrusion 214a and the second protrusion 215a. I can.

Here, the locking portion 214 has a gap corresponding to the thickness of the window rail 310 on which the drain hole 321 is formed, and the inner circumference of the drain hole 321 is fitted, and the fitting portion 215 is the inner cap 100 The inner circumference of the opening 112 is fitted while having a gap corresponding to the thickness of the inner circumference of the opening 112 formed in the enclosure 110 of ).

Therefore, when the outer cap 200 is inserted from the outside of the drain hole 321, the locking piece 213 generates an elastic effect, and the inner circumference of the drain hole 321 is in both locking portions 214 of the locking piece 213 The outer cap 200 is fixed to the outside of the drain hole 321 by being fitted, and at this time, the fitting portion 215 of the locking piece moves downward from the rear of the drain hole 321 as it is naturally located inside the drain hole 321 As the inner circumference of the opening 112 formed in the housing 110 of the inner cap 100 to be installed is fitted into the fitting portion 215, the inner cap 100 is fixed by the outer cap 200, and the inner cap The opening 112 of the 100 naturally coincides with the drain hole 321.

On the other hand, the outer cap 200 may be installed in the drain hole 321 while being combined with the inner cap 100 to form an insect repellent cap, but without the use of the inner cap 100, only the outer cap 200 ′ is formed. It could be.

When only the outer cap 200 ′ is installed in the drain hole 321 without the use of the inner cap 100 to form an insect repellent cap, only the engaging portion 214 is configured on the engaging piece 213 as shown in FIGS. 8 and 9. , Rainwater flowing into the window frame frame 300 is discharged to the outside through the hole 211 formed in the outer cap 200' body 210, and the hole 211 so that pests are not introduced through the hole 211 ), a blocking member 216 such as a mesh net may be installed, and the blocking member 216 may be installed to be assembled into the hole 211 as needed.

Looking at the detachment process of the insect repellent cap according to an embodiment of the present invention configured as described above is as follows.

That is, when the insect repellent cap installed in the drain hole 321 of the window frame 300 as in FIGS. 4 and 5 is composed of only the inner cap 100', the enclosure 110 of the inner cap 100' By descending between the rail 310 and the screen rail 320 and fixed to the rear of the drain hole 321 of the screen rail 320, by matching the opening 112 and the drain hole 321 of the enclosure 110, the window frame frame 300 ), rainwater flowing into the interior of the enclosure 110 can be discharged to the outside of the window frame 300 through the through hole 113 of the enclosure 110 through the drain hole 321 matching the opening 112, and the drain hole 321 Pests introduced through) are captured in the space 111 of the enclosure 110 or cannot be introduced into the room, and are again passed out of the drain hole 321.

And when removing pests trapped in the space 111 of the enclosure 110 or cleaning or inspection of the inner cap 100', the enclosure 110 located between the window rail 310 and the screen rail 320 The inner cap (100') is simply separated from the window frame frame 300 by raising it while holding both sides of the box, and then removing the pests captured in the space 111 of the enclosure 110, and the inner cap ( 100') can be cleaned and inspected.

In addition, as shown in FIGS. 8 and 9, when the insect repellent cap installed in the drain hole 321 of the window frame 300 is composed of only the outer cap 200 ′, the locking piece 213 located at the rear of the body 210 When inserted into the drain hole 321, the hole 211 of the body 210 and the drain hole 321 naturally match, and the locking portion 214 of the locking piece 213 is fixed to the drain hole 321, so that the window frame frame Rainwater flowing into the interior of the 300 may be discharged to the outside of the window frame 300 through the drain hole 321 and the hole 211 of the body 210, and the hole 211 of the body 210 Pests introduced through the body 210 may be blocked by the blocking member 216 installed in the hole 211 of the body 210.

And when separating the outer cap 200' from the drain hole 321 for reasons such as cleaning and inspection of the blocking member 216 or the outer cap 200', if both locking pieces 213 are collected inward, the locking part ( Since the inner circumference of the drain hole 321 is off from 214, the outer cap 200' is pushed outward of the drain hole 321 to be separated simply and quickly.

In addition, when the insect repellent cap installed in the drain hole 321 of the window frame 300 is composed of the inner cap 100 and the outer cap 200, the outer cap 200 as illustrated in Figs. The outer cap 200 is first fixed to the drain hole 321 by inserting the locking piece 213 into the drain hole 321 so that the inner circumference of the drain hole 321 is inserted into the locking portion 214 of the locking piece 213 Then, when the case 110 of the inner cap 100 is lowered vertically from the upper side of the window rail 310 and the screen rail 320, the inner circumference of the opening 112 formed in the enclosure 110 is drained through the drain hole 321 As it is inserted into the fitting portion 215 of the outer cap 200 and the engaging piece 213 passing through the inner cap 100 and the outer cap 200 with the drain hole 321 therebetween, the inner cap 100 and the outer cap 200 are firmly and simply It can be combined.

At this time, the inflow of pests is blocked by the space 111 formed in the enclosure 110 of the inner cap 100, so the blocking member 216 is not required in the hole 211 of the outer cap 200, but if necessary Accordingly, the blocking member 216 may be installed in the hole 211 of the outer cap 200. For example, if the blocking member 216 with a wide gap is installed in the hole 211 of the outer cap 200 Even if the blocking member 216 is not a pest, it can prevent the inflow of foreign substances such as fallen leaves or small stones, so that the insect repellent cap can be used more effectively, cleanly and safely.

In addition, if the inner cap 100 and the outer cap 200 are combined with the drain hole 321 in between and the inner cap 100 needs to be cleaned or inspected, the inner cap 200 is left as it is. When 100 is lifted to separate the inner circumference of the opening 112 of the housing 110 from the fitting portion 215 provided in the engaging piece 213 of the outer cap 200, the inner cap 100 is As it is simply separated from 300), it can be cleaned or inspected, and after cleaning or inspection, the inner cap 100 can be lowered back to its original position and installed simply.

In addition, when cleaning or inspection of the outer cap 200 is required, the outer cap 200 cannot be separated from the drain hole 321 in a state in which the inner cap 100 is coupled, so the inner cap 100 is raised while the inner cap 100 is raised. When the piece 213 is gathered inward and pushed outward, the locking part 214 of the locking piece 213 is released from the inner circumference of the drain hole 321, so that the outer cap 200 can be simply separated from the drain hole 321. On the contrary, when the outer cap 200 is coupled to the drain hole 321, the locking piece 213 can be pushed into the drain hole 321 to be simply coupled.
