Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a screen door that is fitted into a sash or the like.

[Conventional technology]

Conventionally, a pair of vertical and horizontal frames were connected to corner blocks at the four corners to form a rectangular screen door.

[Problem that the invention attempts to solve]

Conventional screen doors use L-shaped corner blocks to connect the vertical and horizontal frames, and are constructed from a combination of three members, which makes processing and assembly of each member complicated, and especially When assembled, the rigidity of the corners was extremely weak, making long-term use difficult.

Therefore, an object of the present invention is to provide a screen door that solves the above problems.

[Means for solving problems]

In order to solve the above problems, the present invention provides a screen door configured in a rectangular shape with a pair of vertical frames and a pair of horizontal frames, in which the vertical frames protrude from the main body portion and both ends thereof in the direction of the horizontal frames. The projecting portion has a U-shape as a whole, and the projecting portion is characterized in that it is integrally provided with a joint to be fitted into the hollow portion of the horizontal stile.

The above-mentioned pair of vertical and horizontal frames have grooves for meshing that communicate with each other formed on their inner peripheral surfaces. Further, the vertical frame and the protruding portion are integrally formed of synthetic resin.

[Effect]

Because the vertical stile also serves as a corner block,
There are fewer parts, and the corners that connect to the horizontal frames are more rigid, making the whole structure stronger.
When the vertical frame is made of synthetic resin, it is manufactured using a mold, so processing is not complicated.

Assembling is easy, as all you have to do is fit a pair of horizontal frames into the joint of one vertical frame, and then assemble one of the vertical frames.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Since the screen door 1 has the same shape on both sides, the right half is omitted in Fig. 1, but a pair of vertical frames 2 on the left and right
(only the left side is numbered) and a pair of upper and lower horizontal frames 3 and 4 are assembled to form a rectangular frame.

The left stile 2 is the same as the right stile, but includes a main body portion 2a and protruding portions 2b and 2c that protrude from both ends in the directions of the horizontal stile 3 and 4, and these are integrally molded from synthetic resin, making the overall structure It is formed in the shape of a letter. Furthermore, each of the protruding portions 2b, 2c is integrally formed with long and short joints 2d, 2e, 2f, 2g that fit into the two-stage hollow portions 3a, 3b, 4a, 4b of the horizontal frames 3, 4. These long and short joints 2d~
2g is arranged so that the short joints 2f, 2g are at the outer positions, and the short joints 2f, 2g are provided with rail grooves 2h, 2i continuous with the protruding parts 2b, 2c, as shown in FIG. ing. The upper and lower horizontal frames 3 and 4 are provided with cuts 3c and 4c in the hollow portions 3b and 4b in accordance with the rail grooves 2h and 2i, allowing them to run on the rails.

Furthermore, the vertical frame 2 and the horizontal frames 3 and 4 have netting grooves 2j, 3j, and 4j that communicate with each other on their inner peripheral surfaces.
This provides convenience for setting up the net after the framework. In the figure, numeral 6 is a handle and 7 is a string. When assembling the screen door 1, the end faces of the upper and lower frames 3 and 4 are applied to the joints 2d and 2e of one vertical frame, for example, the left frame 2, and the hollow parts 3a, 3b, 4a,
4b into the long and short joints 2d to 2g, and assemble the right stile in the same way. There is a concave groove 2 in the assembled frame.
A net 5 is stretched on the side where j, 3j, and 4j are located, and a string 7 is fitted into the grooves 2j, 3j, and 4j through the net 5. The excess screen 5 protruding from the grooves 2j, 3j, and 4j is cut off, and the screen door 1 is completed.

[Effect of idea]

As described above, according to the present invention, processing and assembly are easy, the rigidity of the corner portions is increased, and it is possible to use the device in a stable state for a long period of time.
