Specific details for implementing the invention

[0029] The configuration and operation according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0030] This is intended to provide a detailed explanation sufficient for a person skilled in the art to easily implement the contents of the present invention, and does not imply that the technical concept and scope of the present invention are limited thereby.

[0031] In addition, it should be noted that when assigning reference numerals to the components of each drawing, identical components are denoted by the same numeral whenever possible, even if they are shown in different drawings; furthermore, terms specifically defined in consideration of the structure and operation of the present invention may vary according to the intent or convention of the user or operator, and the definition of such terms needs to be determined based on the content throughout this specification.

[0032] First, the components of a window frame equipped with an interlocking insect screen according to the present invention can be broadly classified into a window frame (100) equipped with an outer window rail (110) and an inner window rail (120) as shown in FIGS. 1 to 3, a window sash (200) consisting of an outer window (210) and an inner window (220) that move along the outer window rail (110) and the inner window rail (120), and an insect screen (300) installed between the outer window rail (110) and the inner window rail (120) and operated in conjunction with the inner window (220). The components will be examined in more detail through the illustrated drawings.

[0033] First, the window frame (100) is,

[0034] It is installed on a wall or similar structure separating the interior and exterior, supports a window sash (200) to be described later that is installed on the inner perimeter of a window frame (100), and guides the sliding of such a window sash (200).

[0035] A plurality of rails for sliding the window sash (200) are installed on the inner perimeter of the window frame (100). Specifically, an outer window rail (110) is installed on the outside, and an inner window rail (120) is installed on the spaced-in inside.

[0036] The window (200) is,

[0037] The window frame (100) described above includes an outer window (210) and an inner window (220) installed overlapping in the front-rear direction on the inner perimeter of the window frame (100), wherein the outer window (210) is installed on the outer window rail (110) of the window frame (100) and slides along the outer window rail (110), and the inner window (220) is installed on the inner window rail (120) of the window frame (100) and slides along the inner window rail (120), and the interior can be opened and closed according to the operating state of the inner window (220) and the outer window (210).

[0038] The window sash (200) may specifically be composed of a window sash frame forming the outer perimeter and glass installed inside such a window sash frame, and a rail groove to which the rail of the aforementioned window frame (100) is coupled is provided on the outer perimeter of such a window sash frame, and a roller or the like may be installed on the lower side of the window sash frame to assist in sliding operation.

[0039] The insect screen (300) is,

[0040] It is installed in the window frame (100) together with the aforementioned window sash (200) and is positioned in the open area when the window sash (200) is opened, serving to block pests from entering the room.

[0041] Conventional insect screens are installed on the outer insect screen rail of the window frame located on the outside of the window sash, so they always obstruct the view regardless of whether the window sash is opened or closed, and they have the disadvantage of being exposed to the outside, making them susceptible to contamination or damage.

[0042] The present invention overcomes the disadvantages of such conventional insect screens by linking the insect screen with the window sash so that the insect screen unfolds or folds according to the opening and closing of the window sash, thereby preventing obstruction of the view caused by the insect screen and also preventing contamination or damage.

[0043] An embodiment of the insect screen (300) according to the present invention is specifically described in FIGS. 1 to 3 as follows.

[0044] The insect screen (300) according to the present invention may be configured to include a fixed bar (310), a movable bar (330), and a mesh member (320), and the insect screen is installed between an outer window rail (110) and an inner window rail (120).

[0045] The fixing bar (310) is installed on the floor surface between the outer window rail (110) and the inner window rail (120) located on the side of the inner perimeter of the window frame (100), and can be configured with a length corresponding to the upper and lower length of the side of the inner perimeter of the window frame (100).

[0046] A movable bar (330) that is spaced apart from a fixed bar (310) has a length corresponding to that of the fixed bar (310) and can be moved in both directions along the longitudinal direction between the outer window rail (110) and the inner window rail (120) of the window frame (100).

[0047] The separated fixed bar (310) and the movable bar (330) are connected through a mesh member (320), and as one side of the mesh member (320) is connected to one side of the fixed bar (310) and the other side of the mesh member (320) is connected to one side of the movable bar (330), the fixed bar (310), the unfolded mesh member (320), and the movable bar (330) form a roughly rectangular shape.

[0048] As shown in FIG. 2, the movable bar (330) may have a protruding catch (321) formed on its inner surface, and when the front end of the side frame (221) of the inner window (220) is moved toward the inner perimeter side of the window frame (100) to close the inner window (220), the front end of the side frame (221) of the inner window (220) is caught on the catch (321) as shown in FIG. 1.

[0049] That is, when moving to open the inner window (220) in a closed state as shown in FIG. 3, the movable bar (330) is moved together, causing the folded mesh member (320) to unfold and the open part of the inner window (220) to be blocked by the mesh member (320). When moving to close the inner window (220) in an open state, the front end of the side frame (221) of the inner window (220) touches the catch (321) of the movable bar (330), causing the movable bar (330) to move toward the fixed bar (310), thereby causing the unfolded mesh member (320) to fold as shown in FIG. 1.

[0050] Here, when the inner window (220) is closed and the mesh member (320) is folded, the inner window (220) is opened. Since the movable bar (330) does not move unless the user intentionally grasps and moves the inner window (220) together with the movable bar (330), the movable bar (330) can be left as is and only the inner window (220) is opened as in FIG. 2 as needed, so that the mesh member (320) is not covered and a completely open state can be achieved.

[0051] Meanwhile, as an embodiment to allow the movable bar (330) to naturally move together when the inner window (220) is opened or closed for the convenience of using the insect screen (300), the stopper (321) is made of an elastic material and connected to the movable bar (330), and a fitting groove is formed on the surface of the stopper (321) facing the inner window. Then, when the side frame (221) of the inner window (220) moves toward the movable bar (330), the leading edge of the side frame (221) of the inner window (220) is elastically fitted into the fitting groove of the movable bar (330), so that the side frame (221) of the inner window (220) and the movable bar (330) are fixed to each other, and the movable bar (330) may move together in conjunction with the opening or closing of the inner window (220). If it is desired to separate the side frame (221) of the inner window (220) from the movable bar (330) and move it, The side frame (221) of the inner window (220), which is elastically fitted into the groove of the movable bar (330), can be easily separated and moved by pulling it.

[0052] Here, since it is difficult for the leading edge of the side frame (221) of the inner window (220) to be directly inserted into the insertion groove of the movable bar (330), it is preferable to form a protruding insertion hole at the leading edge of the side frame (221) of the inner window (220) and to configure the structure so that this insertion hole is inserted into the insertion groove of the movable bar (330) and fixed.

[0053] In this way, when the inner window (220) and the movable bar (330) are linked together, when the inner window (220) is opened, the mesh member (320) naturally unfolds over the open area to block the open area, and when the inner window (220) is closed, the mesh member (320) naturally folds, thereby preventing contamination or damage to the mesh member (320) and ensuring a good view of the outside through the closed inner window (220).

[0054] In another embodiment for the convenience of using the insect screen (300) so that the movable bar (330) can naturally move together when the inner window (220) is opened or closed, as illustrated in FIGS. 1 to 3, at least one magnetic body (322) may be installed along the longitudinal direction on one side of the movable bar (330) in the direction toward the inner window (220) from the catch (321), and the front end of the side frame (221) of the inner window (220) may also be configured to be connected to each other by magnetic force by installing a magnetic body (222) at a corresponding position facing the magnetic body (322) of the catch (321).

[0055] Here, the magnetic body (322)(222) may be exposed to the outside, but if fine iron powder in the air adheres to it and causes corrosion, the surface of the magnetic body (322)(222) may be easily contaminated and the bonding force due to magnetic force may be weakened. Therefore, a soft, thin protective cover through which magnetic force can pass may be wrapped around the magnetic body (322)(222), or the magnetic body (322)(222) may be installed so that it is received inside the catch (321) or inside the front end of the side frame (221) of the inner window (220), so that the magnetic body (322)(222) is not exposed to the outside.

[0056] Meanwhile, when the fixing bar (310) is installed between the outer window rail (110) and the inner window rail (120) located on the inner side of the window frame (100), it may be directly fixed to the floor surface between the outer window rail (110) and the inner window rail (120) located on the inner side of the window frame (100), but preferably, as shown in FIG. 3, a guide bar (340) in the shape of "└┘" is first installed along the vertical length direction between the outer window rail (110) and the inner window rail (120), and the fixing bar (310) is inserted and fixed to the guide bar (340), thereby configuring the fixing bar (310) to be detachable from the guide bar (340).

[0057] Here, when the ends of the movable bar (330) and the guide bar (340) are extended to form extension parts (331) (341), as the movable bar (330) moves to the fixed bar (310) and the mesh member (320) is folded, the extension parts (331) (341) come close to each other as shown in FIG. 1, so that the folded mesh member (320) is not exposed to the outside but is received and concealed within the extension parts (331) (341) of the movable bar (330) and the guide bar (340), thereby preventing contamination and damage to the mesh member (320) and making the overall appearance beautiful.

[0058] In addition, as illustrated in FIG. 1, if one extension (331) of the movable bar (330) is bent in a stepped manner to form a fitting groove (323) on the inner surface, when the mesh member (320) is folded, the extension (341) of the guide bar (340) is fitted into the fitting groove (323) formed in the extension (331) of the movable bar (330) and fixed to each other, thereby preventing the movable bar (330) from moving unnecessarily while the mesh member (320) is folded and the mesh member (320) from unfolding arbitrarily.

[0059] Meanwhile, the mesh member (320) has multiple holes formed on its surface to prevent insects from entering, and is made of a flexible material that is installed between the fixed bar (310) and the movable bar (330) so that it can be unfolded or folded according to the movement of the movable bar (330).

[0060] The mesh member (320) can be configured as a zigzag shape with folds formed in the vertical direction maintaining a constant spacing along the length direction, for example, as a folded mesh or a bellows mesh.

[0061] Although the insect screen (300) is not illustrated in the drawings as another embodiment, a drum-shaped fixed rod is rotatably installed between the outer window rail (110) and the inner window rail (120) located on the inner perimeter side of the window frame (100), and one end of the mesh member is elastically wound several times around this fixed rod, and a movable bar (330) is installed at the other end of the mesh member, and the movable bar (330) is configured to be fixed by being hooked onto the side frame (221) of the inner window (220). When the movable bar (330) moves along the space between the outer window rail (110) and the inner window rail (120) of the window frame (100) together with the window sash (200) to open the window sash (200), the mesh member is released from the fixed rod and the mesh member is unfolded. When the movable bar (330) moves to the opposite side together with the window sash (200) to close the window sash (200), the mesh member It gets wrapped around the fixed rod again.

[0062] Meanwhile, as illustrated in FIG. 4, between the outer window rail (110) and the inner window rail (120) located on the upper side of the inner perimeter of the window frame (100), and between the outer window rail (110) and the inner window rail (120) located on the lower side of the inner perimeter of the window frame (100), an upper guide bracket (130) in the shape of "┌┐" and a lower guide bracket (140) in the shape of "└┘" may be installed facing each other to guide when the upper and lower ends of the mesh member (320) are moved.

[0063] Here, a spacing adjustment member is attached to one side of the inner surface of the upper guide bracket (130), and the end of such spacing adjustment member (131) is made to contact the floor surface between the outer window rail (110) and the inner window rail (120) on the upper side of the inner perimeter of the window frame (100), and the other side of the inner surface of the upper guide bracket (130) can be fastened to the floor surface between the outer window rail (110) and the inner window rail (120) on the upper side of the inner perimeter of the window frame (100) through a screw (132).

[0064] Here, the spacing adjustment member (131) and the screw (132) may be installed to penetrate directly into the inner surface of the upper guide bracket (130), but as shown in FIG. 5, an installation groove (135) may be formed along the longitudinal direction on one upper surface of the upper guide bracket (130) so that the spacing adjustment position can be freely moved, and an auxiliary bracket (133) may be configured to be fitted and moved by forming a fastening hole (134) so ​​that the spacing adjustment member (131) and the screw (132) can be fastened into such an installation groove (135).

[0065] The need for such a gap adjustment device (131) is not relevant when the window frame (100) is constructed normally, but as shown in FIG. 6 (a), if the upper part of the window frame (100) is lifted during the construction process, a large gap may occur between the upper part of the mesh member (320) and the inner surface of the upper guide bracket (130), allowing pests to enter. Also, if the upper part of the window frame (100) sags, the upper part of the mesh member (320) may come into contact with and be pressed against the inner surface of the upper guide bracket (130), which may prevent the mesh member (320) from unfolding and folding smoothly.

[0066] Accordingly, when fixing the upper guide bracket (130) to the floor surface between the outer window rail (110) and the inner window rail (120) on the upper side of the inner perimeter of the window frame (100), the gap between the inner surface of the upper guide bracket (130) and the upper surface of the mesh member (320) is appropriately adjusted as shown in Fig. 6 (b) by rotating the gap adjuster (131) in the forward or reverse direction, thereby preventing the entry of pests and preventing unnecessary interference between the upper surface of the mesh member (320) and the inner surface of the upper guide bracket (130) when the mesh member (320) is unfolded and folded. Once the adjustment of the gap adjuster (131) is completed in this manner, the upper guide bracket (130) can be fixed to the floor surface between the outer window rail (110) and the inner window rail (120) on the upper side of the inner perimeter of the window frame (100).

[0067] Meanwhile, as illustrated in FIGS. 7 to 9, slide grooves (150) are formed in the upper guide bracket (130) and the lower guide bracket (140) respectively so that the upper and lower ends of the mesh member (320) can be guided more effectively through the upper guide bracket (130) and the lower guide bracket (140), and at least one slider (350) is installed in each of the upper and lower ends of the mesh member (320), and a catch (351) that can be selectively caught and moved in the slide grooves (150) of the upper guide bracket (130) and the lower guide bracket (140) may be formed protrudingly at the end of such slider (350).

[0068] That is, the slide groove (150) is composed of an opening (151) having a predetermined width along the longitudinal direction while forming a step on the other side of the inner surface of the upper guide bracket (130) and the lower guide bracket (140), and an internal space (152) formed inside the opening (151) that is larger than the opening (151). The catch (351) of the slider (350) is approximately rectangular, and the length of the short side (353) is formed shorter than the width of the opening (151) formed in the slide groove (150). By making the long side (352) of the catch (351) parallel to the longitudinal direction of the slide groove (150), the catch (351) can be inserted through the opening (151) of the slide groove (150) and moved into the internal space (152). In this state, if the catch (351) is rotated so that the long side (352) is no longer parallel to the longitudinal direction of the slide groove (150), The long side (352) of the catch (351) is caught on the inside of the opening (151) formed in the slide groove (150), so that the catch (351) is not disengaged through the opening (151) formed in the slide groove (150).

[0069] Accordingly, when the mesh member (320) is installed on the upper guide bracket (130) and the lower guide bracket (140) using the slider (350) fixed to the top and bottom of the mesh member (320), as shown in FIG. 8 (a) and (b), an external force is applied to move the movable bar (330) as far as possible from the fixed bar (310) so that the wrinkles of the mesh member (320) are completely flattened. Consequently, the long side of the catch (351) formed on the slider (350) becomes horizontally parallel to the longitudinal direction of the slide groove (150). In this state, the catch (351) is inserted into the internal space (152) through the entrance (151) of the slide groove (150). Then, when the external force applied to completely flatten the wrinkles of the mesh member (320) is removed, as shown in FIG. 9 (a) and (b), by the wrinkles of the mesh member (320) As the mesh member (320) is folded into a basic state, the long side (352) of the catch (351) located in the internal space (152) becomes inclined from a horizontal state, and the long side (352) of the catch (351) catches on the entrance (151) of the slide groove (150), so that the catch (351) is not separated from the slide groove (150).

[0070] Meanwhile, when a lower guide bracket (140) is installed on the inner perimeter bottom side of the window frame (100), the drain hole (111) of the outer window rail (110) located on the inner perimeter bottom side of the window frame (100) can be covered by the lower guide bracket. Therefore, as shown in FIGS. 10 and 11, one or more spacing members (160) are installed between the outer window rail (110) and the inner window rail (120) located on the inner perimeter bottom side of the window frame (100) so as not to interfere with the drain hole (111), and by installing the lower guide bracket (140) by seating it on the spacing member (160), the phenomenon of the drain hole (111) of the outer window rail (110) being blocked by the lower guide bracket (140) can be prevented.

[0071] In addition, since the position of the drain hole (111) of the outer window rail (110) may vary depending on the specifications of the window frame (100), it is preferable to form a fixing groove (141) along the longitudinal direction on one side of the inner surface of the lower guide bracket (140) and to form a fixing projection (161) on the upper surface of the spacing member (160) so that it can be inserted into such a fixing groove (141) and slide.

[0072] As described above, the detailed description of the present invention has explained specific embodiments, but it is understood that various modifications are possible within the scope of the described content. Therefore, the scope of the described content does not need to be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
