Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen door stopper for preventing a screen door from being detached between upper and lower rails provided on upper and lower frames of a sash. The indoor side rail, which protrudes from the frame to the upper rail for the screen door parallel to the longitudinal direction above the screen door frame,
The present invention relates to a screen door stopper for restricting a movement allowance of a screen door upper frame above and preventing the screen door from being detached in a state where the screen door is mounted between the upper projecting members on the outdoor side.

[0002]

2. Description of the Related Art Conventionally, screen doors are provided on the outermost side of a shoji that opens and closes windows and entrances of buildings. This screen door is not always used like glass shoji, but is used only during the season when insects are likely to occur, such as in summer, so it is required to be inexpensive and lightweight so that it can be easily removed, Frequently, they easily fall out of the sash frame.

[0003] Generally, the screen door is mounted between the upper and lower rails for the screen door provided on the sash frame by a "kendon type".
That is, the upper door rail suspended from the upper sash frame is lifted so as to be sandwiched between upper and lower indoor and outdoor projecting members projecting in parallel above the upper screen door frame, and then protruded from the lower sash frame. The screen door is lowered so that the door wheel mounted in the lower frame of the screen door is placed on the lower rail for the screen door, but after mounting, the upper part of the screen door upper frame on the indoor side and outdoor side There is a considerable gap between the upper surface of the horizontal member between the bases of the protruding members and the lower end of the upper door rail suspended from the upper sash frame. The presence of this gap allows the screen door to be attached and detached in a fast-moving manner, but this also causes the screen door to come off.

For example, as shown in a sectional view of a sash with a screen door shown in FIG. 9, a screen door 7 has a screen door upper rail 3 hanging from a sash upper frame 1 extending vertically above the screen door upper frame 9. After being lifted so as to be sandwiched between the upper and lower projecting members 12 and 13 on the indoor side and the outdoor side projecting over the entire length in the direction, the door wheel 17 mounted in the screen lower frame 16 is projected to the sash lower frame 2. It is mounted in a "Kendon type" that is lowered onto the lower rail 4 for screen doors. In this state, the upper projecting members 12 and 13 on the indoor side and the outdoor side in the screen door upper frame 9 are provided.
Since there is a gap between the upper surface of the horizontal member 10 between the bases of the sash and the lower end of the screen door upper rail 3 suspended from the sash upper frame 1, the screen door 7 can move upward. Due to the vibration or the like, the door roller 17 may completely fall off from the screen door lower rail 4 protruding from the sash lower frame 2, or one of the door rollers 17 may be displaced and the screen door 7 may be distorted.

Therefore, in order to prevent such a phenomenon from occurring, conventionally, a plate-shaped screen door stopper having a long hole formed in a vertical direction in order to restrict a moving allowance of the screen door upper frame upward. A screw whose upper end is positioned slightly lower than the lower surface of the horizontal portion of the upper frame of the sash, and which is inserted through the long hole, is screwed into a predetermined position of the upper side projecting member on the indoor side protruding above the upper door frame. A method has been adopted in which the sash is fixed to the upper frame of the sash by screwing and fixing the female screw provided.

However, according to this method, not only must a screwdriver be provided for rotating the screw when adjusting the mounting height position of the screen door stopper, but also the position of the screen door stopper is located at the top of the screen door frame. Since it is located at the top, when adjusting the mounting height position of the screen door stopper, a stepladder must be prepared, and if the screws are weakly tightened, gravity will lower the screen door stopper. It has a drawback in that it does not fulfill its role and if the screws are strongly tightened, the screen door stopper will be damaged.

[0007]

SUMMARY OF THE INVENTION The drawbacks of the conventional screen door stopper are solved, and the mounting height position of the screen door stopper can be easily adjusted by operating a fingertip without preparing a special tool. Not only can reliably function as a detent effect that restricts the upward movement of the screen door upper frame, but also the mounting height of the screen door detent at a low position near the top of the net attached to the screen door It is an object of the present invention to provide a screen door stopper which can adjust the position, and which can easily release the stopper effect when the door is not used, such as when cleaning the door or in winter.

[0008]

As a result of various studies to solve the above-mentioned problems, the present inventor has found that the horizontal member between the indoor and outdoor projecting members projecting in parallel above the screen door frame above. A through hole vertically penetrating at a predetermined position is formed, and a screen door stopper is inserted into this through hole so that the uppermost portion is positioned immediately below the lower end of the upper door rail suspended from the sash upper frame. It has been found that the above problem can be solved by adopting a structure which can be mounted so that the height of the mounting can be adjusted in the vertical direction.

That is, according to the present invention, the upper door rail hanging from the upper frame of the sash is mounted so as to be sandwiched between the upper and lower indoor and outdoor projecting members projecting in parallel above the upper door frame. For the screen door, which is inserted vertically into the horizontal member between the upper protruding members of the screen door upper frame of the screen door, and is inserted into a through hole formed in parallel with the longitudinal direction, and the uppermost portion is located immediately below the lower end of the screen upper rail. A leg which can be deformed so as to reduce the distance between the ends by the elasticity of the material around the upper end below both sides of the upper gate-shaped portion, and which can be inserted through the through hole, is a stopper. Further, the present invention relates to a screen door stopper, wherein serrations are formed on the outside of the legs at predetermined intervals to engage with the horizontal member of the screen door upper frame.

Further, in such a screen door stopper, if a spring portion for restoring the shortening of the distance between the ends is formed between the legs, the mounting height position of the screen door stopper is repeatedly adjusted. It is possible to effectively prevent the occurrence of a phenomenon in which the serrations formed on the outside of the leg at predetermined intervals due to the settling of the material and cannot be maintained in the engagement state with the horizontal member of the screen door frame at the predetermined interval, When the knobs are formed at the outer lower ends of the legs, respectively, they can be well engaged with the fingertips for shortening the distance between the ends of the legs, and also have a function of protecting the fingertips. Is provided with an engaging portion formed with a cushion contact portion that is formed in an arc shape via a space portion, the mounting height position of the screen door stopper is adjusted, and as a result, the sash is moved when the screen door is moved. Lower end of upper door rail suspended from upper frame There is no phenomenon that the screen door cannot be moved even if the upper end of the screen door stopper comes in contact with it, and the gate-shaped part penetrates vertically through the horizontal member of the screen door upper frame and drills parallel to the longitudinal direction. In the case of a shape that can be inserted through the provided through-hole, if a locking portion having a width and / or length greater than the width and / or length of the through-hole is provided on the top of the gate-shaped portion, the screen door When adjusting the mounting height position of the screen stopper, the screen door stopper does not fall out of the through hole drilled in the screen door upper frame so that it can be operated safely and the longitudinal side of the locking part If one of the is provided with a sliding projection that engages with a notch groove formed in the vertical direction on the upper projecting member on the outdoor side of the screen door upper frame, the mounting state of the screen door stopper is defined.
