The slide rail 16 is attached to the upper frame 1 in advance, and after assembling the opening frame A and attaching to the building, the movable vertical frame MJ of the screen door C is connected to the slider portion 18 of the slide rail 16 via the connection fitting 21. The upper ends of the movable vertical frames MJ are suspended by connecting the upper ends of the movable vertical frames MJ.

Since the slider portion 18 is fitted to the retainer 20 with a required length, the movable vertical frame MJ can be moved in a direction parallel to the opening surface or in a direction perpendicular to the opening surface. It is possible to move very lightly in the longitudinal direction of the upper frame 1 without lateral swing, that is, while maintaining a complete vertical state.

The connecting metal fitting 21 has its upper end fixed to the slider portion 18 in advance by a screw 22a, and its lower end fixed to the outdoor surface of the movable vertical frame MJ with the screw 22b. The frame MJ can be easily separated from the upper frame 1.

At the lower end of the movable vertical frame MJ, as shown in the lower part of FIG. 5, a plastic lower member 23 having at least a part of the sectional shape equal to that of the movable vertical frame MJ is formed on the upper surface thereof. The pair of engaging projections 24 are pushed into the lower end of the movable vertical frame MJ to be integrally connected. An engaging piece 25 is fixed to the indoor side surface of the lower member 23 with a screw 22c. The engaging piece 25 is provided in a state where the engaging portion 25a is fitted in the guide groove 9 of the lower frame 2 in advance when assembling the opening frame A. When the movable vertical frame MJ is attached to the opening frame A, The engagement piece 25 is screwed to the lower member 23.

In this manner, the movable vertical frame MJ can move in the longitudinal direction of the upper frame 1 without the upper end being swayed by the slide rail 16, and the lower end is swayed via the engagement piece 25. It is possible to move in the longitudinal direction of the lower frame 2 without performing. That is, even when a force in the opening and closing direction is applied at an arbitrary height, the movable vertical frame always moves vertically in FIG. 1 while maintaining a vertical state.

As shown in FIGS. 3, 4, 5, and 8, the movable vertical frame MJ has a cross section formed in a substantially H-shape, and a winding shaft that opens to one of the vertical frames 3 with respect to the central web 26. It has a storage groove 27 and a net storage groove 28 that opens on the opposite side of the winding shaft storage groove 27 with respect to the web 26. The opening surface of the winding shaft housing groove 27 is shielded by a shielding member 29 fitted and fixed to the movable vertical frame.

As shown in FIG. 7, a pair of ridges 29b and 29c bent in opposite directions are provided on the front and back of a strip 29a having a width substantially equal to the web 26, as shown in FIG.
As shown in FIG. 8, as shown in FIG. 8, the pair of ridges 29 c on the back surface are fixed by being fitted between the distal ends of a pair of vertical walls forming the winding shaft housing groove 27. . The magnetic plate 30 is fixed at a plurality of predetermined heights between the pair of ridges 29b on the surface.

A winding shaft 31 that is continuous from the upper end to the lower end thereof is rotatably held inside the winding shaft housing groove 27. The upper end is rotatably supported by a bearing 32 (FIG. 2) provided inside the upper end of the movable vertical frame, and the lower end is rotatably supported by a support shaft 33 protruding from the upper surface of the lower member 23. The winding shaft 31 has an upper end protruding slightly above the upper end of the movable vertical frame, and a pinion 34 is fixed to the protruding portion.
Are engaged with a rack 35 extending in the longitudinal direction of the upper frame 1 and attached to the inner surface of the indoor-side hanging wall 7 a forming the groove 7 of the upper frame 1. Therefore, when the movable vertical frame MJ is moved in a direction parallel to the opening surface of the opening frame A, the winding shaft 31 is rotated in the winding direction or the rewinding direction.

The bottom of the mesh storage groove 28 of the movable vertical frame MJ,
That is, a pair of fitting grooves 36 are formed on the winding shaft 31 side as an example, and one longitudinal edge of a net 37 formed in the fitting grooves in a bellows shape is formed thick. Fixed part 37
a can be fitted and fixed. The structure for fixing the one edge of the net to the movable vertical frame MJ is arbitrary. The pleats 37c of the folded and shortened net can be stored in the net storing groove 28 of the movable vertical frame MJ.

A fixing portion 37b formed by forming the other end of the net 37 to be thick is formed so as to open opposite to the opening surface of the housing portion 13 of the other vertical frame 4 of the opening frame A. It is fixed to the opening frame A by being pushed into the groove 13a (FIG. 3).

As shown in FIG. 2, the winding shaft 31 has
An annular recess 3 at a position spaced in the height direction.
1a is formed, and one end of a string 38 such as a plastic rope or a wire rope is penetrated into a small hole through which the winding shaft is penetrated in a concave portion thereof, and a stopper is connected to a tip of the string 38 to thereby remove the string 36. Is connected to the winding shaft 31. The concave portion 31a of the winding shaft 31 is for guiding the string at the time of winding the string and for reducing the maximum winding diameter as much as possible. However, a spool may be fixed to the winding portion of the string.

Each of the strings 38 is fixed to a fixing portion 37a of the net 37,
The string is horizontally passed through a small hole formed in the fixing portion 37b and each pleat 37c therebetween, and the other end of the string is free of the spring 15b of the spring unit 15 attached to the housing portion 13 of the vertical frame 4. It is connected to the end. Thus, all the strings 38 are always kept in tension.

The operation of the above configuration will be described. Since the movable vertical frame MJ has its upper end suspended from the upper frame 1 by the slide rail 16 and moved, the movable vertical frame MJ can be moved in a direction parallel to the opening surface of the opening frame A or in a direction perpendicular to the opening surface. , Swinging is effectively prevented. In addition, the lower end of the movable vertical frame MJ is similarly prevented from swinging in a direction parallel to and perpendicular to the opening surface of the opening frame by the engagement piece 25. Therefore,
The movable vertical frame MJ smoothly maintains a vertical state and smoothly moves in a direction parallel to the opening surface even when an opening / closing force is applied at an arbitrary height.

When the movable vertical frame MJ is moved to the left in FIG. 1, the net 37 is extended and the screen door is closed as shown in FIG. When the closing member 29 approaches the closing member 14 of the vertical frame 3, the magnetic plate 30 is attracted to the magnet MG, and is fixed in the closed state. Further, the shielding member 29 is in close contact with the soft member S. Therefore, the collision sound of the movable vertical frame does not occur when the screen door is closed. Insects are prevented from entering between the movable vertical frame MJ and the vertical frame 3. When the movable vertical frame MJ is moved to the right, the net 37 is shortened and the screen door is opened as shown in FIG. Therefore, it is possible to open the door B and freely pass through the entrance.

The take-up shaft 31 is rotated by the action of the pinion 34 and the rack 35 along with the movement of the movable vertical frame MJ. In FIG. 3, when moving the movable vertical frame MJ to the right, the winding shaft 31 is rotated in the winding direction according to the amount of movement, and the string 38 is wound. Therefore, no matter where the movable vertical frame MJ exists, the string 38 always maintains a tensioned state and prevents the net from becoming loose. On the other hand, in FIG.
Is moved to the left, the winding shaft 31 is similarly rotated in reverse according to the amount of movement, and the string 38 is rewound from the winding shaft. Since the other end of the string is connected to the spring 15b, even if there is a slight difference between the amount of movement of the movable vertical frame MJ and the amount of rotation of the winding shaft 31, the string is always in a required tension. Maintain the condition to prevent the net from loosening. In addition, the movable vertical frame MJ
Is smoothly moved while maintaining a completely vertical state by the slide rail 16, so that the meshing state of the pinion 34 and the rack 35 does not collapse, so that the winding shaft 31 is moved in accordance with the movement of the movable vertical frame MJ. Since it is reliably rotated, only a part of the string is not loosened.

One end of a string 38 that keeps the net 37 parallel to the opening surface so that the net 37 is not bent by wind or human beings is pulled by a spring 15b and the other end is wound around a winding shaft 31. It is always in tension. Therefore, the string may be tightly wound at the time of winding, and the string may not be smoothly rewound when the net is closed, or the string may be deteriorated and cut, requiring replacement. Thus, when it becomes necessary to correct the winding state of the string or to replace the string, the closing member 29 is required.
Can be easily removed from the movable vertical frame MJ.

In the above embodiment, the slide rail 16
The rail portion 17, the retainer 20, and the slider portion 18 were attached by fitting the rail portion 17 to the door stop wall 6 of the upper frame 1 using a ready-made product in which the rail portion 17, the retainer 20, and the slider portion 18 were previously assembled in a factory or the like. In the case of this example, the slide rail 16 can be relatively easily incorporated into the upper frame 1 of the opening frame A. The configuration formed on the upper frame 1 for fixing the rail portion 17 of the slide rail 16 has an advantage that there is no particular limitation.

However, in order to incorporate the slide rail 16 into the upper frame 1, the rail portion 17 is integrally formed with the door stop wall 6 of the upper frame, and the retainer 20 and the slider portion are formed on the rail portion before assembling the opening frame. 18 can be attached by fitting the combined one. In the case of this embodiment, the effect of saving the used material can be obtained.

In order to mount the engagement piece 25 for guiding the lower end of the movable vertical frame MJ movably in the longitudinal direction of the lower frame 2, the lower portion used to support the lower end of the winding shaft 31 is mounted. The present invention is not limited to the case where the engagement piece 25 is fixed to the member 23, and the engagement piece may be directly fixed to the lower end of the movable vertical frame MJ. The engagement portion 25a of the engagement piece 25 may be formed by a roller. Further, the guide member of the lower frame 2 is not limited to the groove 9. Any shape that guides the engagement piece in the longitudinal direction of the lower frame may be used.

When the area covered by the mesh on the opening surface of the opening frame is variously different, meshes having different widths are used, and the width in the shortened state (distance between the right and left edges) is also different. A movable vertical frame having a different depth of the net storage groove 33 according to the width of the net is used.

When the slide rail 16 and the engagement piece 25 are detachably connected to the movable vertical frame MJ by screws or the like as in the above embodiment, the slide rail 16 and the engagement piece 25 Has the advantage that any movable vertical frame having a different mesh storage groove depth can be mounted in the same manner using the same one.

Although the above embodiment is applied to the entrance, the present invention can also be applied to a window similarly, and has the same operation and effect.

[0044]

As described above, according to the present invention, the slide rail is attached to the outdoor side hanging wall forming the groove of the upper frame, and the movable vertical frame is suspended from the slider portion. Since the movable vertical frame is moved stably along the slide rail, the meshing state of the pinion and the rack is reliable,
The pinion does not separate from the rack. Therefore, the moving amount of the movable vertical frame and the winding amount or rewinding amount of the string by the winding shaft match, so that the movable vertical frame can be moved and the net can be opened and closed reliably and smoothly.

Further, when the winding shaft housing groove of the movable vertical frame is closed by a detachable closing member, the closing member is removed when necessary to replace the string wound around the winding shaft. Maintenance can be easily performed.
