DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen door improved so that it can be smoothly opened and closed without being easily dislodged even when a mounting frame to be mounted has an irregular opening height.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a device disclosed in Japanese Utility Model Application No. 53-181871 (Japanese Utility Model Application Laid-Open No. 55-92772).
In this invention, an adjusting tool consisting of a corner tool and an adjusting bar is urged upward by a leaf spring fitted to the corner tool, and the screen door is mounted between the upper rail and the lower rail of the mounting frame. Then, the screen moves while the adjuster is elastically pressed against the upper rail. In addition, after adjusting the adjustment tool up and down, a method of fixing the adjustment tool so that it cannot be moved up and down is also performed, and a method of fixing a separate stopper other than the adjustment tool by adjusting the adjustment tool up and down is also commonly performed in a fitting. I have.

[0003]

The mounting frame for mounting the screen door has an incorrect opening height, that is, when the upper rail and the lower rail are not parallel (the center portion of the upper rail is bent downward, Rails may be diagonal instead of horizontal)
In that case, when the screen door of the above-mentioned conventional example runs, the adjuster moves up and down following the rail frame without coming off the upper rail, but is opened and closed while moving, but since the screen door is light, it is caught by a little resistance during running. Trying to be diagonal. Then, there is a problem that the rear of the adjusting tool is pushed into the upper rail, the screen door is lifted, and the door roller of the lower rail is disengaged from the lower rail.

[0004] Further, by tightening a screw which is screwed into a vertical piece of the above-described conventional corner tool, the corner tool and the adjustment bar are fixed. If the rail and the lower rail are not parallel, raising the fixed position of the corner tool and adjustment bar makes it difficult to separate from the upper rail, but when the upper rail is bent downward, etc., opening and closing is not smooth or impossible When the fixed position is lowered, there is a problem that the upper rail is easily detached from the upper rail. Furthermore, in the method of adding and fixing another stopper (usually a plate made of synthetic resin), if the stopper comes into contact with the upper rail while the screen is running, the resistance increases and the opening and closing is smooth. There is a problem that it is not carried out, and it is also conceivable to use a door pulley (adjustment tool or upper rail is equipped with a door pulley), but in that case the opening and closing will be smooth, but the number of parts is There is a problem that the cost increases and the size increases.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a screen door in which an adjusting tool having a door roller is vertically movably mounted on an upper rail, and the adjusting tool is attached upward by a spring. It is urged and prevented from falling, it is made to be able to move up and down within a certain range, and the stopper that prevents the downward movement of the adjustment tool can be fixed to the screen door body or the adjustment tool by changing the vertical position, By fixing the stopper at an arbitrary position, the downward movable amount of the adjusting tool can be adjusted.

[0006]

The present invention is configured as described above.
Even if the adjustment tool is pressed against the upper rail of the mounting frame by the upward biasing force and the opening height is incorrect, the screen door is opened and closed while moving up and down following it, adjusting the vertical position of the stopper If it is fixed, the adjustment tool will contact the stopper and prevent downward movement beyond a certain level, and the screen door will move up and down up to the range of irregularity of the mounting frame opening height, so that there is no obstacle to opening and closing In addition, the adjustment tool does not move beyond the range, and it is possible to prevent the lower rail from being lifted until the lower rail comes off the lower rail of the mounting frame. In addition, since the adjusting tool having the door roller can be moved up and down and urged upward, the door door is always in contact with the upper rail of the mounting frame even when the screen door is running smoothly or tilting obliquely. State.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment will be described with reference to FIGS. The screen door is composed of an upper beam 1, a lower beam 2 and a vertical beam 3
To form the screen door body A, and corner tools 6 on both sides.
An adjustment bar 5 having a 6 is mounted on the upper bar 1 so as to be vertically slidable. The adjusting tool B includes an adjusting bar 5 and corner tools 6 on both sides thereof. The corner tool 6 includes a rotatable door roller 8 and a spring 7 for urging the adjustment tool B upward, and is provided with a leg 9. 10 are provided. A spring 7 attached to the adjusting tool B comes into contact with the upper rail 1 to generate an upward biasing force. In addition, the adjustment tool B may be only the corner tools 6.

The stopper 12 is formed by bending both ends of a metal plate or the like in the same direction, and contacting the upper and lower portions with contact portions 13 and 14.
Are provided, and a vertically long mounting slot 15 is provided therebetween, and is fixed to the screen door main body A so that the vertical position can be adjusted.
The upper and lower contact portions 13 and 14 come into contact with the corner tool 6 at the same time. The stopper 12 is attached together when the upper beam 1 and the vertical beams 3.3 are assembled. A part of the upper part of the vertical bar 3 is notched and the upper bar 1 is abutted there. A set screw 16 is inserted through the mounting hole 15 of the stopper 12 and the mounting hole 17 of the vertical bar 3, and the screw is screwed into the screw hole of the upper bar 1. And
The upper beam 1 and the vertical beams 3 are assembled, and the stopper 12 is attached.

The stoppers 12 and 14 are provided at the upper and lower portions of the stopper 12 because, when the stopper 12 is adjusted up and down, through the opening 19 of the insect stopper 18 attached to the vertical bar 3 of the screen door. In some cases, only one of the upper part and the lower part of the stopper 12 is visible. In such a case, the adjustment can be made by moving either the visible upper part or the lower part. In short, the stopper 12 can be easily moved from either of the upper and lower portions. However, only one of the contact portions may be provided, and it is not an absolutely necessary condition to provide the stopper at two upper and lower portions. The stopper 12 does not have to be mounted with a set screw 16 for assembling the upper rail 1 and the vertical rails 3. However, if it is used, the cost can be reduced and the assembling strength of the screen door can be enhanced. .

In order to mount the adjusting tool B, the corner tools 6.6 with the spring 7 and the door roller 8 attached thereto are inserted into both ends of the adjusting bar 5, and the corner tools 6.6 and 6 When the 9.9 is inserted into the groove of the vertical rail 3.3, the engaging portion 11
11 is restored over the head of the setscrew 16, 16 and is prevented from falling off by the head of the set screw 16.
The heads of the setscrews 16 are located in the elongated holes 10 for movement of the legs 9 of the corner tool 6, within which the corner tool 6 can move up and down.

To attach the screen door to the mounting frame, first, the set screws 16 on both sides are loosened to stop the stoppers 12.
Into a state where it can be moved up and down (the state shown in FIG. 3), and fitted into the mounting frame. When the upper and lower rails of the mounting frame are parallel, the stoppers 12 and 12 are lifted as they are until the contact portions 13 and 14 abut against the corner tool 6 of the adjusting tool B, and the set screws 16.1.
Tighten 6. If the upper and lower rails are not parallel, move the screen door to the left and right and adjust the stopper B at the lowest position (the position where the dimension between the upper and lower rails of the mounting frame is the smallest).
12 is lifted until the contact portions 13 and 14 come into contact with the corner tool 6 of the adjusting tool B, and the set screws 16 and 16 are tightened (the state of FIG. 4). In short, when the screen door is stopped and the adjusting tool B abuts on the stopper 12 at a predetermined position and cannot be pushed down, the screen door cannot be lifted any more, and the lower rail of the screen door is disengaged from the lower rail of the mounting frame. This makes it possible to smoothly run without slipping off even if the screen door gets stuck during running.

When the screen door travels to a position where the dimension between the upper and lower rails of the mounting frame is larger than the minimum position, the adjusting tool B is slightly raised by the force of the spring 7 (the state shown in FIG. 5).
In both the state shown in FIG. 4 and the state shown in FIG. 5, the adjuster B is always urged upward by the force of the spring and the door roller 8 is always in contact with the upper rail R while the screen door is running.

A second embodiment will be described with reference to FIG. The screen door is constructed by assembling the upper beam 20 and the vertical beam 21 with assembly screws 33.

An adjustment bar 23 having 4 and 24 is attached to the upper bar 20 so as to be vertically slidable. The adjusting tool D includes an adjusting bar 23 and corner tools 24 on both sides thereof. The corner tool 24 has a rotatable door wheel 26 and a spring 25 for urging the adjusting tool D upward, and is provided with a leg 27. An elongated hole 28 and an engaging portion 29 (the same as in the first embodiment) are provided. In addition, the adjustment tool D may be only the corner tools 24.

The stopper 30 is provided with a screw hole 34 substantially at the center of a plate made of metal or the like, and is provided with a contact portion 31 by bending the lower end thereof. Fixed as possible. The stopper 30 is fixed to the corner tool 24 by inserting a set screw 32 from the long hole 28 for movement and mounting of the leg 27 and screwing it into the screw hole 34. To adjust the vertical position of the stopper 30, loosen the set screw 32 and move it up and down.
Can also be moved up and down together, so that the set screw 32 may be tightened and fixed at an appropriate position.

In the first embodiment, the stoppers 12
Is lifted until the contact portions 13 and 14 abut against the corner tool 6 of the adjusting tool B, and the set screws 16 and 16 are tightened. In the second embodiment, the stopper 30 loosens the set screw 32, The contact part 31 is an assembly screw 33 of the screen door main body C.
, And fix it by tightening the set screw 32. Configurations and the like not described in the second embodiment are as follows.
The description is omitted because it is the same as in the first embodiment.

[0016]

As described above, according to the present invention, the screen door is
Even when the opening height of the mounting frame to be attached is incorrect, the adjustment tool moves up and down without coming off the upper rail, and the door of the adjustment tool can be smoothly opened and closed while always touching the upper rail. Even if the screen door is caught by a slight resistance and tries to be inclined, if the opening height of the mounting frame exceeds the range of deviation of the opening height, the stopper will abut against the adjustment tool, and the screen door body will not lift further and will come off the lower rail. There is an effect that almost disappears. In addition, even when the running screen door is about to be inclined, since the force is received by the door of the adjusting tool, the screen door can be opened and closed smoothly.
