Description

[Detailed description of the invention] The present invention relates to a sliding screen door device, and its gist is that a screen door 2 is fitted between an upper frame 1a and a lower frame 1b so as to be freely movable, and a pair of stoppers are provided to prevent the screen door 2 from floating up. 5 and 5 are separated from each other by a distance larger than the width W of the screen door 2, and the upper frame 1a
This relates to a sliding screen door device that is vertically installed from the top surface 4 in the rail groove 3a.

In the conventional sliding screen door device, as shown in FIGS. 1 and 2, an upper frame 1a' and a lower frame 1b' of the screen door frame 1' are attached to the upper and lower parts of the sliding door frame 7 for the sliding door 6. And this upper frame 1
A screen door 2 was fitted between a' and the lower frame 1b' in a so-called Kendon style.

That is, first lift the screen door 2, insert the upper end of the screen door 2 fully into the rail groove of the upper frame 1a', and then lift the screen door 2.
The lower end of the screen door 2 is placed on the lower frame 1b' by standing it straight up and down.

The screen door 2 can be locked by a locking device, and the locking device prevents the screen door from running.
For example, as shown in FIG. 3, a sickle lock 8 attached to the side end of the screen door 2 is locked into a locking groove 9 bored in the sliding door frame 7.

However, on hot summer nights, we often open the sliding door to let in the breeze and then go to bed with the window closed using the sliding door and screen door. While the screen door was rattled up and down using the gap between the top of the rail groove and the top surface of the upper Azusa, the locking device or the screen door itself could come off, making it extremely unsafe from a security standpoint.

This invention was made in view of the drawbacks of the conventional example of slanting.The purpose of this invention is that when the screen door is pushed to one side of the screen door frame, the screen door is held down by the stopper and can be moved up and down. To provide a sliding screen door device which is excellent in crime prevention without the need to worry about the locking device of the screen door being removed by moving the screen door up and down, and which allows the screen door to be easily fitted between the upper and lower frames in a folding manner. be.

The present invention will be explained in detail below with reference to the accompanying drawings.

A screen door frame 1 consisting of an upper frame 1a, a lower frame 1b, and a vertical frame 1C is attached to the four indoor sides of the sliding door frame 7 for the sliding door 6, and a screen 10 is stretched inside this screen door frame 1. Fit the screen door 2.

The upper surface of the lower frame 1b has a protruding rail protrusion 3b on which the door roller embedded in the lower surface of the screen door 2 is placed so that it can run freely. There is no problem even if it is inset.

A rail groove 3a is recessed in the lower surface of the upper frame 1a in the longitudinal direction thereof, and the upper end of the screen door 2 is fitted into the rail groove 3a.

A gap of an appropriate height is secured between the top surface 4 of the rail groove 3a and the upper end surface of the screen door 2 so that the screen door 2 can be attached and detached from the screen door frame 1 in an easy-to-understand manner. A pair of stoppers 5, 5 are vertically disposed at a distance slightly larger than the width W of the screen door 2 from the top surface 4 to near the height of the upper end surface of the screen door 2.

Therefore, the distance S between the stopper 5 and the vertical frame 1C is smaller than the width W of the screen door 2, and by positioning the screen door 2 between the stoppers 5, the screen door 2 can be moved from the screen door frame 1 by the Although it can be easily attached and detached, by moving the screen door 2 toward the right or left end, the upper end of the screen door 2 is held down by the stopper 5 to prevent rattling.

Here, it is preferable that the distance Q between the top surface 4 of the rail groove 3a and the upper end surface of the screen door 2 is narrow, but at most Q is a dimension that does not allow the screen door 2 to be removed in a knock-down manner.

The stopper 5 may be made of any material such as metal or synthetic resin, but it may be made of any material such as metal or synthetic resin; things cannot be used.

Further, the vertical frame 1C has a recessed groove 11 extending vertically, and when the screen door 2 is moved to the edge, the end of the screen door 2 fits into the recessed groove 11, and the vertical frame 1C allows the screen door to It is possible to suppress rattling in the front-rear direction, and the crime prevention effect is even higher.

12 is a beat 12 protruding from the screen door 2 to prevent insects from entering.
The tip is brought into contact with the sliding door 6 on the indoor side.

Further, a locking device (for example, the same as that shown in the conventional example) is installed between the screen door 2 and the vertical frame 1C.

In the illustrated example, the screen door 2 is a right-side screen door that is moved toward the right side, but a left-side screen door that is moved toward the left side may be used as the screen door 2.

As described above, the present invention is to fit a screen door between the upper frame and the lower frame so that it can run freely, and to install a pair of stoppers for preventing the screen door from floating on the top surface of the rail groove of the upper frame with a distance greater than the width of the screen door. Even though the stopper is installed vertically from the top surface in the rail groove, the screen door can be easily attached and removed from the screen door frame by positioning it in the middle between the stoppers. Moreover, when the screen door is moved to the edge of the screen door frame as in normal use, the screen door is restricted from rising by the stopper, so even if the screen door is moved up and down, it does not wobble much. This has the advantage that the locking device and the screen door itself do not come off while the screen door is rattling when it is locked, making it extremely excellent in crime prevention.
