Further, one or both of two pairs of protruding edges 11a, 11b; 13a, 13b forming the fitting grooves 11c, 11d; 13c, 13d are provided with storage grooves 11, 13 as described later.
It is formed so that a locking edge 14b formed on the back surface of the shielding member 14 for shielding the opening surface of the above can be fitted and locked.

With the above configuration, in the screen door of the present embodiment, the opening and closing direction of the screen and the moving direction of the movable vertical frame MJ can be set to both the left and right. That is, the movable vertical frame MJ can be connected to either the left or right side of the net 37. Now, an example in which the movable vertical frame MJ is connected to the left side of the net will be described. In this case, the opening of the storage groove 11 of one vertical frame (the vertical frame close to the movable vertical frame MJ when the screen door is closed, and the left vertical frame 3 in FIGS. 1, 3, and 4) is shielded by the shielding member 14. ing.

As shown in detail in FIG. 5, the shielding member 14 is formed by integrally forming a pair of locking edges 14b on the back surface of the band plate 14a, and is continuous with the center of the surface of the band plate 14a in the longitudinal direction. At the position corresponding to the magnetic plate 30 attached to the MJ shielding member 29 of the movable vertical frame to be described later, the magnet MG is fixed to the groove 14c formed as described above by press-fitting. A soft member (not shown) such as mohair extending to the surface of the magnet MG is fixed to the portion by fitting. The shielding member 14 is
As shown in FIG. 5, the locking edge 14b is

In the storage groove 13 of the other vertical frame (the vertical frame close to the movable vertical frame MJ when the screen door is opened, and the right vertical frame 4 in FIGS. 1, 3 and 4), a bellows-like foldable net 37 is provided. The urging unit 15 constituting a tensioning means that constantly applies a urging force in the tensioning direction to the string 38 that penetrates and supports the cord 38 in the horizontal direction is fixed. As shown in FIG. 6, the urging unit 15 includes a case 15a, a coil spring 15b as an urging member having one end fixed in the case, and a coil spring 1
Case 1 in which the string 38 connected to the other end of 5b is turned half way
And a roller 15c pivotally attached to the case 5a.
5a is provided with a mounting portion 15e having a hole 15d for screwing into the storage groove 13 of the vertical frame 4. Therefore, the urging unit 15 is attached to the opening frame A so as to be easily detachable.

The roller 15c converts the moving direction of the string 38 into a substantially perpendicular direction (horizontal direction and vertical direction) in order to couple the string 38 to the coil spring 15b arranged so that the biasing direction is substantially vertical. It is for doing. With the above configuration of the urging unit 15, the longitudinal direction of the urging unit 15 can be arranged in a vertical direction, that is, the longitudinal direction of the vertical frame 4 can be aligned, so that the urging unit 15 can be There is an advantage that the space of the vertical frame can be effectively used when installing in a space.

When a sufficient space in the vertical direction can be ensured in the vertical frame 4, as shown in FIG. 7, the roller 15c is omitted from the urging unit 15, and the coil spring 15b is disposed in the horizontal direction. It is also possible to configure the urging unit 15A described above. In this case,
The longitudinal direction of the urging unit 15A is the horizontal direction.

At the upper and lower ends of the indoor side of the door stop wall 6 of the upper frame 1, fitting grooves 6a and 6b are formed so as to face each other, and a slide rail 16 is mounted in these fitting grooves. It is. As shown in FIGS. 8 and 9, the slide rail 16 has concave small ball rolling surfaces 17a, 17
b, a rail 17 extending in the longitudinal direction of the upper frame 1 of the open frame, and concave and small ball rolling surfaces 18a and 18b opposed to the small ball rolling surface of the rail at both upper and lower ends. A short slider 18 and a retainer 20 for rotatably holding small balls 19a and 19b such as a plurality of steel balls for rolling on the small ball rolling surfaces of both rail members while being spaced apart in the longitudinal direction of each rail member. It consists of

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

The slider 18 is fitted to the retainer 20 with a required length, so that the movable vertical frame MJ can be horizontally moved in a direction parallel to the opening surface and 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 swinging, that is, while maintaining a complete vertical state.

The connecting metal fitting 21 has its upper end at the slider 1
8, the movable vertical frame MJ can be easily attached to and detached from the upper frame 1 because the lower end portion is fixed to the outdoor surface of the movable vertical frame MJ with the screw 22b. it can.

At the lower end of the movable vertical frame MJ, as shown in the lower part of FIG. 7, a plastic lower member 23 having at least a part of a 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.

When the storage groove 13 is not provided on the back side of the vertical frame 4, the movable vertical frame M is required when the slider 18 of the slide rail has a required length to secure the movement stability.
When J is moved to the end in the screen door opening direction, that is, between the vertical frames 4, the movable vertical frame connected to the slider is stopped because the leading end of the slider comes into contact with the vertical frame first and stops. It may not be possible to move until it comes into contact with the vertical frame 4. However, since the storage groove 13 is provided on the back side of the vertical frame 4, the slider 18 can move to the upper end portion of the biasing unit storage groove 13, so that the movable vertical frame can move until it comes into contact with the vertical frame 4. There is an advantage that the opening amount of the opening surface can be maximized.

As shown in FIGS. 3 and 4, the movable vertical frame MJ has a substantially H-shaped cross-sectional shape, and the winding shaft housing groove 2 that opens toward the one vertical frame 3 with respect to the central web 26.
7 and a web housing groove 28 which opens on the opposite side of the winding shaft housing 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. 5, the shielding member 29 has a pair of ridges 29b and 29c bent in opposite directions on the front and back of a strip 29a having a width substantially equal to the web 26.
As shown in FIG. 5, as shown in FIG. 5, the pair of convex 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 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 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. Further, 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, and the pinion 34 is provided in the groove 7 of the upper frame 1. 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 7a that forms 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 vertical edge of a bellows-shaped net 37 is formed so as to be foldable in the fitting grooves. The fixing portion 37a formed in the above can be attached so as to be able to be freely inserted and removed. On the other hand, the fixing portion 37b formed by forming the other end of the net 37 to be thick is a part of the other vertical frame 4 of the opening frame A.
Can be removably attached to fitting grooves 13c and 13d which are open to the opening surface of the storage groove 13 facing the indoor and outdoor directions. The pleats 37c of the folded and shortened net can be stored in the net storing groove 28 of the movable vertical frame MJ.

The winding shaft 31 has an annular concave portion 31a formed at a position spaced apart in the height direction, and a plastic rope or a wire rope or the like is formed in a small hole through the winding shaft in the concave portion. Through one end of the string 38,
One end of the string 36 is connected to the winding shaft 31 by connecting a stopper to the tip. Recess 3 of winding shaft 31
1a 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 other end of 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 formed by the spring 15b of the biasing unit 15 attached to the storage groove 13 of the vertical frame 4. Connected to the free end. The string 38 has one end wound around the winding shaft 31 and the other end connected to the urging unit 15. Therefore, the cord 38 holds the net 37 in a state where the urging force of the coil spring 15b of the urging unit 15 always acts in the tensioning direction to maintain the tensioned state.

Next, the opening and closing operation of the screen door having 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, even when the movable vertical frame MJ is provided with an opening / closing force at an arbitrary height, the movable vertical frame MJ always maintains a vertical state and smoothly moves in a direction parallel to the opening surface.

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. 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.

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 therefore, the width in the shortened state (distance between the left and right 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 screwing 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.

Next, the case where the left and right hand of the screen door is changed will be described. The urging unit 15 is shown in FIGS.
, Is attached to the storage groove 11 of the left vertical frame,
7 has a fitting groove 11c of the left vertical frame.
11d is fitted and fixed. The string 38 having one end coupled to the free end of the coil spring 15b of the biasing unit is
The half of the roller 15c of the urging unit makes a half turn so that each pleat of the mesh penetrates, and the other end of the mesh is formed in the mesh storage groove 28 of the movable vertical frame MJ.
After passing through the fixing portion at the other end of the net fixed to the bottom of the movable frame, the hole formed in the web of the movable vertical frame provided in the opposite direction to that shown in FIGS. Then, the other end of the string is connected to the winding shaft 31. And the right vertical frame 4
The storage groove 13 is shielded by fitting and locking the same shielding member as the shielding member 14 upside down.

As described above, the storage groove and the fitting groove are provided so as to communicate with the indoor side on both the left and right sides, so that the urging unit and one of the vertical edges of the net are attached to the vertical frame. Since the exchange can be easily performed, the right and left hand of the screen door can be easily set or changed.

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

The urging unit 15 is housed in the housing groove 11 or 13 provided in the indoor part of the vertical frames 3 and 4 and is attached, so that it is not seen from the indoor side, so that the appearance is good. Also,
Instead of closing the storage groove of the vertical frame not storing the biasing unit with the closing member 14, the protruding edge 29b of the closing member 29 of the movable vertical frame may be fitted into the storage groove.
In this case, the magnet M is located between the protruding edges 11a and 11b.
