The present invention aims to provide a sealing structure for the gap between the upper and lower frames and the upper and lower sections of a folding type pleated insect screen, which can perfectly seal the exterior from the interior by blocking even the gaps caused by the spatial difference that arise when the pleated insect screen having a folding structure is folded or unfolded by moving a movable frame.

Description

Technology Field

[0001] The present invention relates to the upper and lower frames of a folding type pleated insect screen having a foldable structure and a sealing structure for the upper and lower gaps of the insect screen. More specifically, when an insect screen that can be folded and unfolded in a pleated manner is not required or is used as an entrance door, the screen is folded to open the window of the entrance door; conversely, when an insect screen is required, the screen is unfolded to block the window, thereby preventing the intrusion of various pests such as mosquitoes and flies into the interior. In the case of such a folding or unfolding insect screen, the insect screen connected to one end of the movable frame moves along with the movement of the movable frame to unfold in a pleated manner. When the upper and lower ends of the insect screen are unfolded and approach the upper and lower frames, which are the outer frames of the pleated insect screen, a space is created between the upper and lower frames of the insect screen and the upper and lower ends of the unfolded insect screen. Since a gap is formed due to this spatial difference, the exterior and interior are not completely sealed off, and external foreign substances, mosquitoes, insects, etc., can enter through said gaps. Therefore, the invention relates to a method for sealing even said gaps. This invention relates to the upper and lower frames of a folding type pleated insect screen and a sealing structure for the upper and lower gaps of the insect screen. Background Technology

[0002] Generally, most pleated insect screens available on the market adopt a manual method, which involves manually moving the screen with a folding structure to fold and unfold it as needed, and is installed on windows and doors as a means to prevent various pests such as mosquitoes and flies from entering the interior.

[0003] These conventional pleated insect screens have a folding structure, and when insect-blocking functions are needed, the moving frame connected to one side of the screen is manually moved to unfold the screen and block the window, thereby preventing various pests such as mosquitoes and flies from entering the room. Conversely, when insect-blocking functions are not needed, the moving frame is moved to fold the screen, thereby opening the blocked window.

[0004] At this time, as the above-mentioned moving frame is guided by the upper and lower frames constituting the outer frame of the pleated insect screen and slides, the insect screen connected to one side of the moving frame is also guided at its upper and lower ends close to the upper and lower frames. Due to the structural characteristics of the pleated insect screen having such a folding structure, a space is created between the upper and lower frames and the upper and lower ends of the insect screen, and a gap is formed due to the difference in space, so the outside and inside are not completely blocked, raising a problem that foreign substances, mosquitoes, insects, etc. from the outside may enter the inside.

[0005] Therefore, when installing pleated insect screens, it is desirable to ensure that even the gaps caused by the difference in space between the upper and lower frames and the upper and lower parts of the screen are sealed. Prior art literature

[0006] Japanese Patent Publication No. JP 9-296669 (November 18, 1997) Korean Patent Publication No. 10-2005-0093900 (September 23, 2005) The problem to be solved

[0007] The present invention was devised to resolve the conventional problems described above, and its main purpose is to provide a sealing structure for the gap between the upper and lower frames and the upper and lower sections of a folding type pleated insect screen, which can perfectly seal the exterior from the interior by blocking even the gaps caused by the spatial difference that arise when the pleated insect screen having a folding structure is folded or unfolded by moving a movable frame.

[0008] In addition, another objective of the present invention is to provide a sealing structure for the upper / lower frames of a folding type pleated insect screen and for the upper / lower gaps of the insect screen, which not only increases economic efficiency by being simply constructed, but also is very convenient to use while ensuring accurate sealing operation despite its simple structure. means of solving the problem

[0009] First, the pleated insect screen according to the present invention is structured such that one end of the insect screen connected to a movable frame is fixed to the left frame, the movable frame to which the insect screen is connected moves from the left frame toward the right frame, and a connecting corner cap is fitted and assembled at the end of the left and right frames so that the upper and lower frames are fitted and assembled again in a horizontal direction, and the movable frame slides along the upper and lower frames to approach and adhere to the left and right frames, thereby folding or unfolding the insect screen. At this time, the direction of movement of the movable frame and the insect screen connected thereto may vary depending on the type of door (single door type, double door type, etc.) and the installation location, and it is assumed that for convenience, the folding is depicted as the left and the unfolding as the right in the drawings of the present invention.

[0010] The present invention for achieving the above objective relates to a folding type pleated insect screen in which a plurality of insect bars (referred to as "insect screens"), having surfaces processed with fine holes, are connected in a horizontal direction with a plurality of hinge bars as an axis,

[0011] When the insect screen is cut in the longitudinal direction, the cut portion formed therein is characterized by being divided into: a finishing member that is fitted; a sealing member that is forcibly fitted onto the finishing member; a slide piece formed in the middle of the sealing member; a locking rim formed integrally at both ends of the slide piece; and a close-fitting piece, wherein the slide piece is characterized by having an incision groove formed therein to provide appropriate tension and flexibility to facilitate fitting when the sealing member is forcibly fitted onto the finishing member.

[0012] In addition, the above-described finishing member has a guide groove and an insertion groove formed on the upper and lower sides of the inner edge partitioned by the inner edge of the guide groove, and a locking edge is integrally formed on the upper inner side of the guide groove, and when the sealing member is forcibly fitted through the guide groove, the slide piece of the sealing member moves up and down along the inner edge of the guide groove, and the contact piece at the end also moves up and down, and in the state where the sealing member is forcibly fitted to the finishing member as described above, the locking edge formed at the end of the slide piece catches on the locking edge of the guide groove, thereby preventing the sealing member from coming off.

[0013] In addition, the sealing member is characterized in that an elastic piece is integrally formed that slopes downward along a line extending from the middle of the bottom surface of the locking rim, and as the sloped end of the elastic piece is supported by the inner edge of the finishing member, the elastic piece is pressed or returns to its original state, and accordingly, the sliding piece of the sealing member moves up and down along the inner surface of the guide groove of the finishing member. Effects of the invention

[0014] According to the present invention as described above, when the insect screen having a folding structure is folded or unfolded through the movement of the movable frame, the gap caused by the difference in space between the upper / lower frame of the pleated insect screen and the upper / lower bottom of the insect screen is blocked, thereby completely sealing the outside from the inside, which has the greatest effect of preventing foreign substances, mosquitoes, insects, etc. from entering the inside.

[0015] Furthermore, the sealing structure of the present invention is very simple, allowing for trouble-free use and significantly extending its service life, thereby increasing economic efficiency. In addition, it is a useful invention with advantages such as convenience of use, as the sealing operation is accurately performed despite the simple structure. Brief explanation of the drawing

[0020] According to the present invention as shown in the drawing above, in a folding type pleated insect screen (W) in which a plurality of insect screens (1), the surfaces of which are processed into fine holes (3), are connected in a horizontal direction with a plurality of hinge bars (2) as a axis,

[0021] When the above insect screen (1) is cut in the longitudinal direction, the cut portion (4) is formed, and a finishing member (5) is fitted therein; a sealing member (6a, 6b) is forcibly fitted to the finishing member (5); a slide piece (7) is formed in the middle of the sealing member (6a, 6b); a locking rim (8) is integrally formed at both ends of the slide piece (7); and a close-fitting piece (9) is formed separately. In the slide piece (7), a cut groove (10) is formed to provide appropriate tension and flexibility so that the sealing member (6a, 6b) can be forcibly fitted to the finishing member (5).

[0022] Meanwhile, the above-mentioned finishing member (5) is divided by an inner edge (11); a guide groove (12) and an insertion groove (13) are formed on the upper and lower sides thereof, and a catch (14) is integrally formed on the upper inner side of the guide groove (12). When the sealing member (6a, 6b) is forcibly fitted through the guide groove (12), the slide piece (7) of the sealing member (6a, 6b) moves up and down along the inner surface of the guide groove (12), and the contact piece (9) at the end also moves up and down. In the state where the sealing member (6a, 6b) is forcibly fitted to the finishing member (5) as described above, the catch (8) formed at the end of the slide piece (7) catches on the catch (14) of the guide groove, thereby preventing the forcibly fitted sealing member (6a, 6b) from coming off.

[0023] On the other hand, in the case of the sealing member (6b), an elastic piece (15) that slopes downward in a line extending from the middle of the bottom surface of the catch (8) is integrally formed, and as the inclined end (16) of the elastic piece (15) is supported by the inner edge (11) of the finishing member (5), the elastic piece (15) is pressed or returned to its original state, and accordingly, the slide piece (7) of the sealing member (6b) is configured to move up and down along the inner surface of the guide groove (12) of the finishing member (5).

[0024] In the drawing, the unexplained reference numeral (17) refers to a movable frame, (18a, 18b) refers to an upper / lower frame, (19a, 19b) refers to a left / right frame, (20) refers to a connecting corner cap, and (21) refers to a roller for moving the movable frame (17).

[0025] The entire pleated insect screen (W) according to the present invention, configured as described above, is completed as the entire pleated insect screen (W) as shown in Fig. 7 by assembling the individual parts disassembled as shown in Fig. 1. After installing the completed pleated insect screen (W) in a window frame or entrance door that is not illustrated, the insect screen (1) having a folding structure is slid left and right by sliding the movable frame (17) to artificially fold or unfold the insect screen (1) when an insect-blocking function is required, thereby blocking the window frame or entrance door to prevent the entry of various pests such as mosquitoes and flies into the room. Since this function and operation are identical to that of a general pleated insect screen, the following description will focus only on the technical gist of the present invention.

[0026] First, according to the present invention, the insect screen (1) having a folding structure through a hinge bar (2) as shown in FIG. 2 is cut to a certain length, and the insertion groove (13) of the finishing member (5) according to the present invention is inserted into the upper / lower cut portion (4) formed by the hinge bar (2), thereby finishing the upper / lower portion of the insect screen (1) with the finishing member (5). Then, the locking rim (8) of the end of the slide piece (7) of the sealing member (6a, 6b) is aligned with the guide groove (12) located on the opposite side of the insertion groove (13) of the finishing member (5) and forced-fitted, thereby easily installing the sealing structure of the present invention on the upper / lower portion of the insect screen (1).

[0027] Meanwhile, in the case of the sealing member (6a, 6b) that is forcibly fitted into the finishing member (5) as described above, appropriate tension and flexibility are provided through the cut groove (10) formed in the slide piece (7), making it easy to forcibly fit, and when forcibly fitted, the catch (8) at the end of the slide piece (7) catches on the catch projection (14) of the guide groove (12) of the finishing member (5), thereby preventing detachment.

[0028] Next, the operation of the sealing structure according to the present invention will be explained.

[0029] First, in the case of the sealing member (6a) that is forcibly fitted into the finishing member (5) installed at the bottom of the insect screen (1), as shown in FIG. 6 (a) and FIG. 7, as the insect screen (1) unfolds, the sealing member (6a) is unfolded as the contact piece (9) extending from the slide piece (7) comes into contact with the lower frame (18b). At this time, as the slide piece (7) moves up and down along the inner surface of the guide groove (12) of the finishing member (5), the sealing member (6a) descends due to its own weight as shown in FIG. 4 (b), and the contact piece (9) comes into contact with the upper surface of the lower frame (18b), thereby blocking the gap created by the difference in space between the lower frame (18b) and the insect screen (1).

[0030] In the case of the sealing member (6b) that is forcibly fitted to the finishing member (5) installed at the top of the insect screen (1), as shown in Fig. 6 (b) and Fig. 7, the sealing member (6b) is unfolded as the contact member (9) extending from the slide member (7) touches the upper frame (18a). At this time, as the slide member (7) moves up and down along the inner surface of the guide groove (12) of the finishing member (5), the sealing member (6b) is supported by the inclined end (16) of the elastic member (15) that slopes downward from the middle of the bottom surface of the locking frame (8) and the inner edge (11) of the finishing member (5), and the elastic member (15) is pressed and then returned, the contact member (9) is in close contact with the lower surface of the upper frame (18a) to block the gap created in the space between the upper frame (18a) and the insect screen (1).

[0031] As described above, by blocking even the gaps caused by the difference in space between the upper / lower frames (18a, 18b) and the upper / lower insect screen (1), the outside and inside are completely blocked, thereby preventing foreign substances, mosquitoes, insects, etc. from entering the inside.
