DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen door whose net can be easily replaced, or to a net structure for the screen.

[0002]

2. Description of the Related Art Aluminum sash screen doors in ordinary houses have become extremely high in all the screen doors in response to the spread of aluminum sash windows. This is similar to the traditional wooden frame screen door in that it is composed of a net and a window frame, but unlike a wooden one, it is difficult to adopt a method of driving a nail into the net and fixing it. Normally, the net is stretched by using the structure and method as shown in FIG.

In other words, a fitting member 22 (often a rubber cord having a thickness just fitted into the concave groove 21) is used to fit into a concave groove 21 orbiting inside the sash frame 20. This is a method in which the parts are fitted and fixed. The work of installing the net 23 is already completed at the product stage, and is not performed by the purchaser after the purchase. If the dust gets clogged up, the buyer must wipe and wash the net, but after a few years, it will loosen or break, so it will be necessary to replace it. Become.

[0004]

However, the net 23
The work of fitting the peripheral portion of the groove into the groove 21 may be wrinkled or distorted if the user is not very skilled. In some cases, the net may not be long enough even though the net is appropriately sized. Sometimes you can.

[0005] The work of stretching the net is performed by the fitting member 2.
When fitting 2 into the concave groove 21, considering the length of a part of the net 23 being drawn into the concave groove 21, it is aesthetically preferable that the entire surface of the net 23 be taut when the work is completed. It is desirable to do some work alone,
I need a point. In other words, for those who are new to the job or who do this only once every few years, the task of replacing the net was impossible.

[0006]

Means for Solving the Problems In view of the above points, the present inventor has finally completed the screen door and the net body for the present invention as a result of intensive research, and the feature thereof is that "screen door ") Is a screen door in which a net is stretched in a frame made of aluminum sash, and the net is a rectangular net main body and the rectangular net for detachably fixing the net to the frame made of aluminum sash. Peripheral edge 4 of shape net body
And a grip frame that grips at least two opposing sides of the sides. In the "net body for screen doors", the screen door is detachably fixed in a frame made of aluminum sash. A rectangular net main body, and a gripping frame for gripping at least two opposing sides of four peripheral edges of the rectangular net main body for detachably fixing the same to an aluminum sash frame. In that it is composed of

Here, the "rectangular net main body" is a sheet-like body having a size corresponding to a meshed portion of a screen door, and is not made of a material different from that of a conventional net. However, unlike the conventional net, it is not mounted by a method of directly fixing the frame to the aluminum sash frame of the screen door main body, but is mounted via a “grip frame”.

The "grip frame" is a frame member fixed to at least two opposing sides of the four sides constituting the rectangular net main body. This is for imparting rigidity to the rectangular net body to hold the shape of the net at the time of stretching work, and for fixing the rectangular net body to the aluminum sash frame of the screen door body. Things. Although there is no particular limitation on the specific structure and material, a plastic plate-like material having shape-retaining properties is suitable for the material. In the structure, the structure of the “fixing portion”, which is a portion for fixing to the frame body of the screen door body, corresponds to the structure of the frame body. The main body itself is greatly different from the case where it is a dedicated product.

[0009] At least two opposing sides of the four sides constituting the rectangular net main body are equivalent to three sides of the rectangle,
It means four sides or two opposite sides. When the gripping frames are provided on all four sides, the width and height of the screened portion of the screen door are limited to one type. However, screen doors generally have different widths even if they have different heights. Therefore, gripping frames are provided only on three sides or two opposite sides, and cut to an appropriate height. The versatility expands and is convenient. In that case, the material of the holding frame is
It is desirable to employ one that is easy to cut.

In the case where the distance between the opposite gripping frames is made variable to some extent by adding an elastic material or the like, and even if the distance between the frame members of the screen door body is slightly different, it can be applied. Usability will be even better.

The method of installing the net for a door into a screen frame according to the present invention is slightly different depending on whether the gripping frame is provided only on two opposing sides or three or more sides. In the case where the grip frame is provided only on two opposing sides, first, the work is started by fixing one grip frame to the screen frame. This fixing is generally of a fitting type, but may be performed by another method (however, the structure must be detachable). At this time, the net (rectangular net main body) can be fixed without sagging or pulling because one side is gripped by the gripping frame. At this time, if the height (or width) of the net is large, it may be temporarily fixed instead of completely fixed.
Next, the other holding frame is fixed (or temporarily fixed) to the screen door. Then, when the height (or width) is large, it is cut into an appropriate size. Then, the work is completed by fixing the two sides having no gripping frame. The fixing method of these two sides may be the same as the conventional fitting member, or may be a rod-like or plate-like member similar to a holding frame. The fixing of the two sides is an operation after the other two sides are properly stretched, so that the operation is very simple.
