Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a stay for a window shoji, and in particular to a stay for a window shoji used for a type of window in which the shoji is sent outside the window frame while being opened. It is related to the stay.

[Conventional technology]

For window shoji, which is equipped with a pair of arms that swingably connect the window shoji to the window frame, and in which one arm sends the window shoji outward from the window frame, while the other arm swings it relative to that arm. status is already known.

This stay is used to hold the window shoji in any open position.
Although the frictional force of the connecting portion is increased, sufficient holding force cannot be obtained. In addition, this stay is used to open and close window shoji by pushing or pulling it by hand.
Therefore, it is not easy to open and close large and heavy window shoji against the wind pressure, and it is dangerous because you have to lean your body out of the window frame.

Also, a stay is known that uses seven crank handles to open and close multiple window shoji installed in a row, but this stay cannot increase the feed stitch of the window shoji, and it is difficult to open and close the window shoji easily. Can not.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a stay for a window shoji that can securely hold the window shoji in its open position, allow the window shoji to be opened and closed safely and easily, and increase the feeding position of the window shoji. It is something to do.

Another object of the present invention is to provide a stay for a window shoji that can easily open and close a plurality of consecutively arranged windows with a large amount of movement using seven crank handles.

[Means to solve the problem]

In order to achieve the above object, the stay for a window shoji of the present invention is provided with a stay for a window shoji that is capable of swinging the window shoji to the window frame (a first arm that is connected in series, and a second arm that swings the window shoji with respect to the first arm). a second arm, a third arm that swings the first arm relative to the window frame, and a reciprocating mechanism that is connected to the second arm and the third arm so that these arms perform two movements to open and close the window sash. It is equipped with a drive rod.

The window sash stay of the present invention further includes a crank handle device for reciprocating the two-part moving rod.

In the window sash stay of the present invention, the stays are each housed in a plurality of consecutive window sashes, each stay is connected to a common drive rod, and the drive rod is connected to a crank handle device. ing.

The window shoji stay of the present invention is provided above and below the window shoji,
These stays are connected by a transmission shaft and operated by a crank handle.

These and other objects of the invention, as well as the features of the invention, will become apparent to those skilled in the art from the following description of the embodiments, which refers to the accompanying drawings.

The window shoji (1) is sent outward from the window frame while swinging around a vertical axis, and in FIG. 1, two pieces are arranged side by side. The two window sashes (1) on the right half are opened and closed with the right crank handle (2a), and the two window shojis (1) on the left half are opened and closed with the left crank handle (2b).

Window shoji stays are provided at the upper and lower ends of each window shoji (1), and each window shoji is swung about the - movable pivot point while swinging around the other fixed pivot points to close the window. Send it out of the frame.

The stay shown in FIG. 1 is attached to the lower end of each window shoji (1) and includes a first arm (3), a second arm (4), and a third arm (5). The first arm fi above
