Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a pulling device for a shoji of a vertical window used in building construction or housing.

[Prior art]

Conventional lift-down windows, such as the one seen in Japanese Utility Model Application Publication No. 59-13574, generally have an upper shoji on the outside of the room and a lower shoji on the inside of the room, and each has a guide groove in the frame. It is designed to be able to slide up and down inside. However, if one shoji is placed on the outdoor side and the other on the indoor side, even when the window is closed, there will be a level difference between the shoji on the indoor side and the shoji on the outdoor side, making it difficult to maintain sufficient watertightness. ,
There is a problem that airtightness cannot be achieved.

Further, Japanese Utility Model Publication No. 56-109386 discloses a single-side up/down window in which the lower part is a fitted window, the upper shoji slides in the vertical direction, and when the door is locked, it can be flush with the fitted window part. However, the shoji had to be raised and lowered without being attached to the window frame, making the appearance unsightly.
The operation is also complicated. Also, it cannot be applied to a raised/lowered window where two shoji screens go up and down.

[Purpose of the invention] This invention's shoji pulling device for a vertical window was developed in view of the above-mentioned problems, and allows two shojis to be pulled along guide grooves provided in the frame of the window. It can be raised and lowered, and when locked, the indoor shoji and the outdoor shoji are constructed so that they are flush or almost flush, and the indoor shoji and the outdoor shoji are drawn together to provide excellent watertightness and airtightness. The purpose is to make it possible to raise and lower windows.

[Structure of the device] The vertical window in this device has an indoor shoji and an outdoor shoji built into the window frame, which consists of an upper frame, a lower frame, and left and right frames. It moves up and down along the indoor guide groove and outdoor guide groove provided in the frame of the window frame.

The indoor shoji is provided with one or more pairs of sliding members that protrude left and right, and slide within the indoor guide groove. On the other hand, the rigid frame of the window frame is provided with a horizontal guide groove that allows the indoor shoji sliding member to move horizontally toward the outdoor side, and when the window is closed and locked, the indoor shoji is guided to the outdoor side, and the indoor shoji It is designed to be flush or nearly flush.

A Gremont device is attached to the upper edge of the indoor shoji, and a pair of arms slides along the top surface of the indoor shoji in a freely retractable manner by operating a handle of the Gremont device. A pull pin is provided upwardly protruding from the upper surface of this arm. On the other hand, a pull block with a cam surface is provided on the lower edge of the outdoor shoji and protrudes downward, and when the pull pin of the arm is pulled by the handle operation of the Gremont device, the pull block moves along the cam surface of the pull block. The pulling pin moves, and the indoor shoji and the outdoor shoji can be pulled together.

Note that, if necessary, a trigger may be provided at the mounting base of the arm to adjust the amount of pull by the Gremont device.

Similarly, for the lower edge of the indoor shoji, pull the arm with the downward pulling pin protruding from it by operating the handle of the Gremont device, and pull it along the cam surface of the pulling block protruding from the top surface of the lower frame.
