Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a screen door mounting structure.

[0002]

2. Description of the Related Art Conventionally, screen doors are often provided with rails on the upper and lower end faces of a rectangular opening, and with grooves on the upper and lower end faces of the screen door. The rail on the upper end surface and the rail on the lower end surface of the opening are respectively inserted into the groove of the opening and the groove of the lower end surface, and are attached to the opening of the building.

[0003] In this screen door, the groove provided on the upper end face of the screen door is usually deep. When mounting the screen door, the screen door is inclined to approach the rail at the upper end face of the opening, and from below, Insert the rail of the upper end of the opening deep into the groove of the upper end of the screen door, raise the lower end of the screen door higher than the rail of the opening, and then vertically insert the rail with the rail inserted into the groove of the screen door. Rotate until
Position the groove on the lower end face of the screen door above the rail on the lower end face of the opening, lower the screen door, and insert the rail on the lower end face of the opening into the groove on the lower end face of the screen door. Then, attach the screen door to the opening.

When the screen door is no longer needed after summer, the screen door is removed and stored in a reverse procedure to the installation. Furthermore, there are fixed screen doors that do not slide, but many of these fixed screen doors have almost the same structure, and when installing or repairing or replacing in the same manner as above, the procedure opposite to the installation is performed. Removed by Thus, many screen doors have a structure that can be easily attached and detached.

[0005]

However, with the screen door attached, a force is applied to the screen door, for example, by wiping the screen portion or the cross section of the screen door, or when a child or the like touches the screen door. In such a case, since the screen door is light, there is a problem that the screen door is easily displaced upward, the groove on the lower end face of the screen door comes off from the rail provided on the lower end face of the opening, and the screen door drops. At this time, if there is a person below the screen door, there is a problem that the person is hit by the screen door or is injured.

To prevent the screen door from moving upward and dropping,
If the groove of the screen door is made shallow, a problem arises in that it becomes difficult to mount the screen door. SUMMARY OF THE INVENTION An object of the present invention is to provide a screen door mounting structure in which the screen door can be easily attached and detached, and which is not easily detached when cleaning or touching a child.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. According to the first aspect of the present invention, rails are provided on an upper end face and a lower end face of a rectangular opening. Grooves are provided on the upper end face and the lower end face of the screen door, and the rails of the upper end face and the lower end face of the opening are inserted into the grooves of the upper end face and the lower end face of the screen door, respectively. A screen door mounting structure in which the screen door is attached to the opening, and a projection having elasticity is provided on the upper side of the screen door so as to always protrude from the end face and to be retracted when pressed, and the protrusion pushes the upper end face of the opening. In a state of being protruded to the vicinity of the upper end face.

In the first aspect of the present invention, an elastic projection is provided on the upper side of the screen door so as to always protrude from the end face and to be retracted when pressed. The projection is formed of a material having rubber elasticity. An elastic body such as a spring, a leaf spring, or rubber may be attached to the projection, and the elastic body may be used to push up or pull up the projection.

According to a second aspect of the present invention, a rail is provided on an upper end face and a lower end face of a rectangular opening, a groove is provided on an upper end face and a lower end face of a screen door, and a groove on an upper end face of the screen door. The rail of the upper end face of the opening and the rail of the lower end face are inserted into the groove of the lower end face, respectively, and the screen door is attached to the opening. A rectangular fall prevention fitting that becomes lower when it is placed horizontally and becomes higher when it is made vertical is rotatably mounted, and that the fall prevention fitting is raised, and the tip of the fall prevention fitting is positioned at the opening. It is in a state where the upper end face is pressed or protruded near the upper end face. The screen door in the present invention includes both a screen door slidably attached and a fixed screen door.

According to the first aspect of the present invention, a projection having elasticity is provided on the upper side of the screen door so as to always protrude from the end face and to be retracted when pressed, and this projection presses the upper end face of the opening or the upper side. Since the screen is protruded to the vicinity of the end face, the screen can be easily attached or removed, and the screen does not come off during cleaning or the like.

To explain this in detail, as in the conventional case, the screen door is inclined and approached from below to the rail at the upper end face of the opening, and the screen door is pushed up to insert the upper side of the opening into the groove at the upper end face of the screen door. Insert the end rail deep. On this occasion,
The screen door is pushed up slightly stronger than before. Then, on the upper side of the screen door, there is provided a projection having elasticity that constantly projects from the end face and retracts when pressed, so that the projection collides with the upper end face of the opening by the force pushing up the screen door and is pressed down. And the lower end of the screen door is higher than the rail at the opening.

Next, with the rail inserted into the groove of the screen door, the screen door is rotated until it becomes substantially vertical, and the groove at the lower end face of the screen door is moved above the rail at the lower end face of the opening. When the force that pushes the screen door upwards is removed, the force that the elastic projection attempts to return to its original state automatically pushes the screen door down, opening the groove in the groove on the lower end face of the screen door. The rail at the lower end of the section is inserted. In this way, the screen door is attached to the opening. In addition, it can be removed in the reverse order of the attachment.

As described above, although a force for pushing up the screen door is required, the screen door can be easily attached and detached in a manner substantially the same as the conventional method. In addition, in the screen door thus attached to the opening, the projection is in a state of pressing the upper end face of the opening or in a state of protruding to near the upper end face, so that the projection cannot be pushed down with a small force. However, the projections hinder the screen door from being easily moved upward. Therefore, the screen door cannot be easily removed only when a small upward force is applied to the screen door, such as when cleaning or when a child touches the screen.

According to the second aspect of the present invention, a rectangular fall prevention metal fitting is provided on the upper side of the screen door so that the height from the end face becomes lower when it is turned sideways and becomes higher when it is made vertical. Since the metal fitting is raised and the tip of the fall prevention metal fitting is pressed against the upper end face of the opening or protruded near the upper end face, the screen door can be easily attached or removed, and The screen door does not come off during cleaning.

To explain this in detail, when the fall prevention metal fitting is vertical, the fall prevention metal fitting is rotated so that the rotation prevention metal fitting is horizontal and low before mounting. Then, as in the conventional case, the screen door is inclined to approach the rail at the upper end face of the opening from below, and the rail at the upper end face of the opening is deeply inserted into the groove at the upper end face of the screen door.

[0016] Then, since the fall prevention fitting is lower, the rail goes deep into the groove of the screen door without the fall prevention fitting becoming a hindrance, and the lower end face of the screen door becomes higher than the rail of the opening. . Next, while keeping the rails in the grooves of the screen door, rotate the screen door until it is almost vertical, and move the groove on the lower end face of the screen door above the rail on the lower end face of the opening, and remove the screen door. Lower down and insert the rail on the lower end face of the opening into the groove on the lower end face of the screen door.

After that, when the fall prevention fitting is rotated and raised, the screen door is attached to the opening. Further, the screen door can be removed in the reverse order. As described above, the screen door can be easily attached or detached in substantially the same manner as in the related art except that the fall prevention bracket is rotated.

Moreover, in the screen door attached in this manner, the fall prevention fitting is in a state where the upper end face of the opening is pressed or protruded to the vicinity of the upper end face.
The fall prevention metal fitting provided on the upper end face of the screen door hinders the screen door from being moved upward. Therefore, even if an upward force is applied to the screen door, such as when cleaning or when a child touches the screen, the fall-prevention metal fittings hinder the screen door from being easily removed.
