Title: Sliding anti-insect window constructing structure having segmented detachable rail frames

Description:
TECHNICAL FIELD 
     The present invention relates to the installation structure of a rail frame for guiding a sliding movement of a roller apparatus of a sliding insect window screen which is capable of supporting a sliding insect window screen and providing a sliding opening/closing action of the sliding insect screen. More particularly, the present invention relates to the sliding insect window screen comprising the rail frame which can more stably support the sliding insect window screen on the top surface and on the bottom surface, so even if a strong wind blows against the sliding insect screen, it is possible for the sliding insect window screen to maintain a stable state without shaking movement. 
     Moreover, the present invention relates to the sliding insect window screen which is appropriate for being installed in front of a sliding window for constituting a special sliding window system. The special sliding window system has a glass panel which is directly and removably seated on and supported by rollers without a quadrilateral door sash that supports the glass panel forming the sliding window so as to minimize a phenomenon of reducing an open view through the sliding window. Also, the glass panel includes vertical stiffeners with an enlarged cross-section (cross-section having a thickness thicker than the glass panel) attached to the both side surfaces of the glass panel so as to reinforce transverse bending rigidity of the glass panel and to exhibit high wind pressure resistance. In this special sliding window system with the above-described structure, upper and lower pocket guides are respectively formed in upper and lower door guide frames used as a window frame member that guides a sliding movement of the sliding window so as to guide the upper end and lower end of the sliding window in both inner and outer surfaces of the sliding window, thereby supporting a smooth movement of the sliding window. In order to allow the sliding window provided with the vertical stiffeners to be integrally installed within a door guide frame, and to allow the sliding window to be separated from the door guide frame in a state where the sliding window is provided with the vertical stiffeners, a pocket guide is formed as pocket guide segments removable from a door guide frame body, and the pocket guide segments are successively installed to be separable from each other on both the inner and outer surfaces of the sliding window along the travel direction of the roller guide rail. 
     BACKGROUND ART 
     The present invention relates to an insect window screen for installation on the outside of the windows in order to prevent indoor entry of various insects, and particularly the insect window screen of the mesh type with being coupled between a lower screen chassis and an upper screen chassis and sliding along the rail provided on the insect window screen installation frame equipped in front of the sliding window installation frame. 
     In general, there are two types of insect window screen. The one type is a fixed insect window screen which is fixed to the window installation frame by using hinge and screws. The other type is a moving insect window screen which is sliding along the rail on the insect window screen installation frame which is additionally constructed in front of window installation frame  10  of a window frame being provided for the window  20  as shown in  FIGS. 1 and 2 . 
     The present invention relates to a moving insect window screen among the above two types of the insect window screen, i.e. a sliding insect window screen or insect window screen in short. According to conventional configurations of the moving insect window screen, as shown by the accompanying drawings in  FIG. 1 , the roller of the lower screen chassis constituting the insect window screen  40  is firmly mounted on the lower rail provided on insect window installation frame  30  in the window frame, but a holder of the upper screen chassis constituting the window screen  40  is no longer in close contact with an upper rail provided on the insect window installation frame  30  of the window frame as shown in  FIG. 2 . Therefore, in a part of the upper rail, there is a problem such as noise generated in case of that the insect wind screen  40  is shaken by the wind. 
     In addition, for example, when a sliding insect window screen is additionally installed to a window system that is provided between the indoor living room the balcony, a special constructing structure of the sliding insect window screen is necessary for that the sliding insect window can be easily installed to the insect window installation frame and separated from the insect window installation frame according to the change of season. However, according to the prior art, in order to adapt the sliding insect window screen for easy installation and removal, there is a problem in that the insect window screen is jerking when it is sliding along the rail and is shaken by wind pressure because of large installation clearance. 
     In order to solve this problem, Korea Patent No. 10-0376971 B1 provided an additional guiding wing member made of soft and elastic synthetic resin to the holder of the upper chassis constituting the insect window screen. According to the additional guiding wing member, when sliding insect window screen is installed into the insect window installation frame of the window frame, the additional guiding wing member of the holder of the upper chassis is pushed into the upper rail of the insect window installation frame and therefore the additional guiding wing member is resiliently bended against the upper rail into a reinforcing rib. To the next, the roller of the upper chassis is placed on the lower rail of the insect window installation frame, and then the additional guiding wing member is resiliently recovered into the original form to firmly contact to the upper rail of the insect window installation frame. As a result of these upper and lower contact structure, shaking by wind pressure could be prevented. 
     However, the above-described structure including the resilient guiding wing member added to the holder of the upper chassis by the Korea Patent No. 10-0376971 B1 has a structural limitation with regard to the wind load proof because of its resilient properties and its short durability based upon soft material. 
     In addition, as described in the prior art with reference to the attached  FIGS. 1 and 2  and the drawings of Korea Patent No. 10-0376971 B1, because that the upper rail and lower rail of the insect window installation frame is exposed, the chassis of the insect window screen may interferes with the visibility of the window. Accordingly, the value of the effort and cost required to remove the door chassis of the glass window for the wide visibility may be compromised by the chassis of the insect window screen. 
     DETAILED DESCRIPTION OF THE INVENTION

     wherein said rail bridge is formed as two or more rail bridge segments which are separately and detachably installed into the inside of said insect window installation frame body pocket, and 
     wherein said rail bridge segments are successively installed and detachably connected under or above the sliding insect window screen along the advancing direction of said rail. 
     Advantageous Effects 
     According to the present invention, an insect window screen can be integrally installed within the insect window installation frame and the installed insect window screen also can be simply separated from the insect window installation frame. Moreover not only the lower chassis constituting the insect window screen but also upper chassis constituting the insect window screen can have a roller member which is more tightly installed into a narrow space so that very smooth sliding movement by the rollers can be achieved both of the upper and the lower rail on the insect window installation frame, and even if a strong wind blows against the sliding insect screen, it is possible for the sliding insect window screen to maintain a stable state without shaking movement. 
     Furthermore, an insect window installation structure according to the present invention, an effect of maximizing durability against the wind pressure with good airtight performance can be achieved. 
     In addition, the upper rail and lower rail of the insect window installation frame is less exposed, therefore the chassis of the insect window screen may not interferes with the visibility of the window.

However, the present invention may be implemented in various forms and is not limited to the embodiments described hereinafter. 
     As described previously, the present invention is intended to solve a problem for the improvement of the sliding insect window installation structure for the insect window screen not to be an obstacle in case of being used together with the special window system having the increased openness of the windows, and also is intended to solve a structural problem produced in case of the installation or separation of the sliding insect screen. Herein,  FIG. 3  is a longitudinal cross-section view of illustrating a sliding insect window installation structure according to the present invention,  FIG. 4  is a plan view of illustrating a sliding window installation structure shown in  FIG. 3 , and  FIGS. 5 to 7  are illustrating usefulness and applicability of a sliding window installation structure with regard to the sliding insect window installation structure according to the present invention. 
     In addition,  FIGS. 8 to 10  are cross-sectional views illustrating the operating states of installation and removal of the sliding insect window screen in case of using the lower structure of the insect window installation structure according to the present invention, and  FIGS. 11 to 13  are cross-sectional views illustrating the operating states of installation and removal of the sliding insect window screen in case of using the upper structure of the insect window installation structure according to the present invention. 
     Moreover,  FIGS. 14 to 19  are plan views illustrating the operating states of removal of the rail bridge and separation of the insect window screen in an embodiment comprising three rail bridge segments in the upper or lower structure. 
     An embodiment of the present invention exemplified in the drawings provides an insect window installation frame  200 , for an insect window screen  500  to be integrally installed within the insect window installation frame  200  and to be simply separated from the insect window installation frame  200 , comprising; 
     an insect window installation frame body pocket  210  which is installed adjacent to a door installation frame  100 ; and 
     a rail bridge  220  being detachably installed into an inside of said insect window installation frame body pocket  210  with including rail  222  extended along the sliding direction of the insect window screen  500  at the position with a pre-determined distance from the bottom surface or ceiling surface of said insect window installation frame body pocket  210 . 
     Whereas, a locking projection  201  may be protruded outside of one side of said insect window installation frame body pocket  210 , and said locking projection  201  can be inserted and coupled into a fastening groove  101  formed on the concave outer side of the door installation frame  100 . 
     In addition, said rail bridge  220  is formed as two or more rail bridge segments  220 - 1 ,  220 - 2 ,  220 - 3  which are separately and detachably installed into the inside of said insect window installation frame body pocket  210 , and said rail bridge segments  220 - 1 ,  220 - 2 ,  220 - 3  are successively installed and detachably connected under or above the sliding insect window screen  500  along the advancing direction of said rail  222 . 
     Preferably, so that said rail bridge  220  having a segmented structure which are separately and detachably installed, i.e. two or more rail bridge segments  220 - 1 ,  220 - 2 ,  220 - 3  can be installed into the inside of said insect window installation frame body pocket  210 , as shown in  FIGS. 3 to 7 , a fastening tab  214  is provided along the advancing direction of said rail  222  in the inner side of said insect window installation frame body pocket  210 , and a inserting projection  224  is provided along the advancing direction of said rail  222  on the inner/outer end of said rail bridge  220  so that said inserting projection  224  can be inserted into said fastening tab  214 . Therefore, based upon the friction generated between said inserting projection  224  and said fastening tab  214 , said rail bridge  220  could not be separated from said insect window installation frame body pocket  210  without applying the external force. However, it is preferred that said inserting projection  224  and said fastening tab  214  are formed so that said rail bridge  220  could be easily detached from said insect window installation frame body pocket  210  when a user grips and pulls said rail  222  extruded from an upper surface of the bridge rail  220 . 
     Further, said rail bridge segment  220 :  220 - 1 ,  220 - 2 , or  220 - 3  being provided as a bridge rail  220 , can be provided into any one or more structure among the upper structure and the lower structure of said insect window installation frame  200 , and as illustrated in the accompanying drawings, the sliding insect window screen  500  have a diversity in the working direction of installation and removal (the sliding insect window screen  500  may be installed/removed in various directions) in case of being provided all of the upper structure and the lower structure of said insect window installation frame  200 . 
     Herein, when said rail bridge  220  are removed from one of the upper structure and the lower structure of said insect window installation frame  200  as illustrated in  FIG. 3 , in order that the sliding insect window screen  500  can be easily separated from the inner surface of said insect window installation frame body pocket  210  of said insect window installation frame  200 , for example, if a distance (refer to b″ of  FIG. 3 ) from the lower end of the sliding insect window screen  500  to the bottom surface of the lower structure of said insect window installation frame body pocket  210  is greater than a distance (refer to a′ of  FIG. 3 ) from the upper end of the sliding insect window screen  500  to the lower end of the upper structure of said insect window installation frame body pocket  210 , said rail bridge  220  is detached from said insect window installation frame body pocket  210  provided in the lower structure of said insect window installation frame  200  (see  FIG. 8 ), and then the sliding insect window screen  500  can be downwardly moved into the free space (see  FIG. 9 ), and then, as the upper end of said insect window screen  500  can be rotated in the forward outside the lower end of said insect window installation frame body pocket  210  of the upper structure (see  FIG. 10 ). Finally, if said insect window screen  500  is slant upwardly lifted in this state, said insect window screen  500  can be removed from said insect window installation frame body pocket  210  of the lower structure (see  FIGS. 8 to 10 ). 
     On the contrary case, said rail bridge  220  is firstly detached from said insect window installation frame body pocket  210  provided in the upper structure of said insect window installation frame  200  (see  FIG. 11 ), and then the sliding insect window screen  500  can be upwardly moved into the free space (see  FIG. 12 ), and then, as the lower end of said insect window screen  500  can be rotated in the forward outside the upper end of said insect window installation frame body pocket  210  of the lower structure (see  FIG. 13 ), and finally if said insect window screen  500  is slant downwardly moved in this state, said insect window screen  500  can be removed from said insect window installation frame body pocket  210  of the upper structure (see  FIGS. 11 to 13 ). Meanwhile, in order that such removal can be easily achieved, a distance (refer to b′ of  FIG. 3 ) from the upper end of the sliding insect window screen  500  to the upper end of the upper structure of said insect window installation frame body pocket  210  should be greater than a distance (refer to a″ of  FIG. 3 ) from the lower end of the sliding insect window screen  500  to the upper end of the lower structure of said insect window installation frame body pocket  210 . 
     Thus, according to the insect window installation structure including the insect window installation frame having a segmented structure which is separately and detachably installed, as shown by the  FIGS. 8 to 10  and  FIGS. 11 to 13 , if said rail bridge segment  220 :  220 - 1 ,  220 - 2 , or  220 - 3  being provided as the rail bridge  220  at any one of the upper structure and the lower structure of said insect window installation frame  200  is removed from the said insect window installation frame  200 , said insect window screen  500  also can be removed from said insect window installation frame body pocket  210 , and the insect window screen  500  assembled through the production line can be integrally installed into said insect window installation frame body pocket  210 . Furthermore, an insect window installation structure capable of maximizing durability against the wind pressure with good airtight performance can be achieved because that a chassis portion of the insect window screen  500  is substantially accommodated in said insect window installation frame  200  as shown in the figures. 
     In addition, in order to improve dust resistance, water-tightness, and air-tightness of the sliding insect window screen system having the above-described structure, as illustrated in  FIG. 3 , blocking members  540  such as mohair may be installed in a horizontal longitudinal direction on the opposite surfaces of said rail bridge segment  220 :  220 - 1 ,  220 - 2 , or  220 - 3  provided as the rail bridge  220  and said sliding insect window screen  500 . 
     Meanwhile, in the case of the sliding insect window screen systems according to the embodiments described above, descriptions will be made on the configuration which allows the rail bridge segments  220 :  220 - 1 ,  220 - 2 ,  220 - 3  provided as the rail bridge  220  to be easily separated from said insect window installation frame body pocket  210  of the insect window installation frame  200  without interference with said sliding insect window screen  500  (refer to  FIGS. 8 and 11 ) and the operating procedure thereof. 
     Hereinafter, embodiments of the apparatus for this removal process will be described with reference to the accompanying drawings such that a person ordinarily skilled in the art to which the present invention belongs may easily embody the present invention. 
     First, as illustrated in  FIG. 4 , said rail bridge segments  220 :  220 - 1 ,  220 - 2 ,  220 - 3  provided as the rail bridge  220  in the upper or lower structure of the sliding window screen  500  are divisionally formed as two or more segments over the entire length of the rail  222  ( FIG. 4  being an illustrative three segments), and one or more segments may be formed to have a length removable from said insect window installation frame body pocket  210  in a state where the sliding insect window screen  500  is installed to be seated on the rollers  520  on the rail  222  of the other segment on the rail bridge  220 . 
     Hereinafter, the operation of the present invention will be described with reference to  FIGS. 14 to 19 , assuming that three rail bridge segments  220 - 1 ,  220 - 2 ,  220 - 3  are divisionally installed as the rail bridge  220  in the upper structure or the lower structure of the sliding insect window screen  500  along the entire length of the rail  222 , as an example. 
     First, when the sliding insect window screen  500  is in the closed state as illustrated in  FIG. 14 , sliding insect window screen  500  is in the state where it cannot be easily removed from the insect window installation frame boy pocket  210  of the insect window installation frame  200  due to the interference between the rail bridge segments  220 - 2 ,  220 - 3  (segments noted by (b) and (c) in  FIG. 14 ) provided as the rail bridge  220  and the sliding insect window screen  500 . However, the rail bridge segments  220 - 3  (segments noted by (a) in  FIG. 14 ) located at a position where the sliding insect window screen  500  is not positioned as illustrated in  FIG. 15  may be removed from the insect window installation frame body pocket  210  of the insect window installation frame  200 . Then, when the rail bridge segments  220 - 2  is slid into the position of the removed the rail bridge segments  220 - 1  as illustrated in  FIG. 16 , so that the rail bridge segments  220 - 2  also can be removed from the insect window installation frame body pocket  210  of the insect window installation frame  200 , as illustrated in  FIG. 17 . 
     In the state illustrated in  FIG. 18  in which two rail bridge segments  220 - 1  and  220 - 2  are removed from the insect window installation frame body pocket  210  of the insect window installation frame  200 , the sliding insect window screen  500  may be removed from the insect window installation frame body pocket  210  of the insect window installation frame  200  as described above with reference to  FIGS. 8 to 10 and 11 to 13 . The state in which the sliding insect window screen  500  is removed is illustrated in  FIG. 19 . 
     Meanwhile, the order performed from  FIGS. 14 to 19  may be referred to as the steps of removing the sliding insect window screen  500  from the insect window installation frame body pocket  210  of the insect window installation frame  200  and on the contrary, the order performed from  FIG. 19  to  FIG. 14  may be referred to as the steps of installing the sliding insect window screen  500  into the insect window installation frame body pocket  210  of the insect window installation frame  200 . 
     The embodiment described above exemplifies a case in which three rail bridge segments  220 - 1 ,  220 - 2 ,  220 - 3  are divisionally installed as the rail bridge  220  along the entire length of the rail  222  in the upper or lower structure of the sliding insect window screen  500 . Unlike this, it can be seen that the present invention may be implemented by divisionally installing the rail bridge segments  220 - 1 ,  220 - 2  having different lengths as the rail bridge  220 . That is, in this case, the rail bridge segment larger than the entire width of the sliding insect window screen  500  may be removed from the insect window installation frame  200  so that the sliding insect window screen  500  may be removed from the insect window installation frame  200  or installed into the insect window installation frame  200  without any difficulty. 
     In addition, according to the concept similar to the present invention, the pocket guide segments  130 :  130 {circle around ( a )},  130 {circle around ( b )}, or  130 {circle around ( c )} provided as the pocket guide  130  supporting sliding window  400  may be provided in an upper structure and/or a lower structure of the door guide frame  100 , and therefore the sliding window  400  can be removed or installed in the door guide frame  100  (refer to  FIG. 20 ). The more detailed descriptions with regard to the entire constitution and operation for this invention, are described in the Korea Patent Application No. 102012-0047789 and the PCT application No. PCT/KR2013/003912 previously filed by inventor and applicant of the present invention, therefore the specification and drawings filed incorporated by reference. 
     The scope of the present invention to be protected is not limited thereto and may cover various types of insect windows to which the present invention is applied, and various modifications and changes using the basic concept of the present invention defined in the accompanying claims also belong to the scope of the present invention.
