Description

[Detailed Description of the Invention] Technical Field There are cases in which a shoji with double-layered glass is fitted in place of a shoji with single-layered glass in an existing window device in order to achieve heat insulation or soundproofing effects.

However, if the existing window frame is used for a single-layer glass shoji, when the double-layer glass shoji is fitted, a part of it protrudes from the window frame, and the screen that was used when the single-layer glass shoji was used becomes unusable.

The present invention relates, for example, to a window frame attachment device for a vertical frame for a screen door, which is attached to a conventional window frame so that a screen door can be used when the screen door is used.

Prior art and its problems As a prior art, for example, Utility Model Application No. 57-183389
There is a method listed in the publication, but this conventional one has a structure where the screen door frame is simply fitted into the window frame vertical frame, so the screen door frame is fitted into the window frame vertical frame. Not only does this require a third member, a holding piece, but it is simply fitted through the holding piece, so attention must be paid to the processing accuracy of each member. There is a risk of it falling off.

Purpose of the present invention The purpose of the present invention is to provide a window frame attachment device that eliminates the defects of the conventional device described above, allows easy attachment work, and prevents the screen door frame from falling off from the window frame vertical frame. It was devised as

Means for Achieving the Object The vertical frame for a screen door is constructed with a U-shaped cross section consisting of an intermediary piece and an internal piece and an external piece provided on both sides of the intermediary piece in the indoor and external directions, and the inside of the vertical frame for a screen door is The outer end piece on the outdoor side of the existing window frame vertical frame is engaged between the vertical frame of the window frame and the outer piece, and the tip of a screw screwed into one of the inner and outer pieces is pressed against the outer end piece. That's what I do.

Embodiment The drawings show an embodiment of the window frame addition device for a screen door vertical frame according to the present invention, where A is an existing window frame, B and B' are window frame A in place of the existing inner and outer shoji with single-layer glass. C is an inner and outer shoji with double glazing equipped with double glazing b, b and b', b' fitted in the inner and outer shoji B,
This is a screen that has been refitted into window frame A to correspond to B'.

1, 1 is the vertical frame of the window frame A, 2, 2 is the outer end piece of the window frame 1, 1 on the outdoor side, that is, on the screen door C side,
The outer end piece 2 constitutes the engagement groove 3 of the vertical stile of the outer shoji B, and 4 is a vertical frame for a screen door attached to this outer end piece 2. The vertical frame 4 is composed of an intermediate piece 5 and an internal piece 6 and an external piece 7 arranged on both sides of the intermediate piece in the indoor/outdoor direction, and has a U-shaped cross section. The outer end piece 2 of the window frame vertical frame 1 is engaged with the outer piece 7 of the vertical frame 4 located on the outdoor side.
Attach the screw 8 from the outside to the appropriate position, screw the screw 8 from the inner surface 7' of the outer piece 7 and tighten it, and connect the tip protruding from the inner surface 7' of the outer piece 7 to the outdoor side of the outer end piece 2. It is constructed by pressing into contact with the

1 to 3 show a first embodiment, in which a U-shaped spring frame 9 is interposed at a proper position between the outer end piece 2 and the vertical frame 4, and the vertical frame outer piece of the spring frame outer piece 9a is 7. The inner piece 9b and the vertical frame inner piece 6 are pressed together to further tighten the screw 8.

This spring frame 9 is not an essential member in applying the present invention, and the second embodiment shown in FIG. 4 shows this example.

In addition, in the figure, 21 is a screen door frame, 22 is an airtight material provided on the screen door frame 2, and the tip of this airtight material is attached to the outer piece 7 of the screen door frame 4 and the vertical frames 23, 23 of the outer shoji B. It is designed so that they are in contact with each other.

Further, the screw 8 may be screwed into the inner piece 6 of the vertical screen frame 4.

Functions and Effects of the Present Invention Since the present invention has the above-described configuration, the screen door vertical frame is assembled to the outer end piece of the window frame vertical frame so as to engage the outer end piece, and the inner and outer pieces of the vertical frame are assembled. When the screws are screwed together from either side, the tips of the screws come into pressure contact with the outer end piece, and when the screws continue to rotate, the screen frame with the screws screwed together moves toward the outdoors or indoors and is fixed in place. It will be done.

Therefore, the present invention is practical because it allows the screen door vertical frame to be securely attached to the existing window frame without falling off, and additional work can be easily performed without requiring special techniques.
