Description

[Detailed description of the invention] The present invention is to attach a stopper to the shoji stile of a vertical sliding window so that its tip always protrudes downward from the lower end of the stile, and to attach a stopper to the horizontal frame of the opening. A stopper receiver is disposed that extends in the longitudinal direction of the frame and has a sliding groove at the lower end of the stopper when the window is opened or closed, and the sliding groove of the stopper receiver is arranged so that the sliding groove is in the direction of the fire direction of the opening horizontal frame. A stopper device for a vertical sliding window is characterized in that the depth gradually decreases from the side toward the outside, and its purpose is to prevent excessive force from being applied to the stopper hardware in the vertical sliding window. An object of the present invention is to provide an improved stopper device for a vertical sliding window, which is configured to close the window in response to the activation of the door.

In this case, as mentioned above, a stopper is attached to the shoji stile of the vertical sliding window so that its tip always projects downward from the stile, and when the vertical sliding window is opened, a stopper is attached. The sliding groove in which the tip of the stopper extends in the longitudinal direction of the open frame provided on the stopper receiver attached to the opening horizontal frame, and whose depth gradually decreases outward from the fire direction side of the open frame. , and automatically fits into the end of the horizontal frame on the fire direction side side of the sliding groove, and the vertical sliding window is held in the open position.

In this state, if an excessive external force such as strong wind or human power is applied to the vertical sliding window, there is a risk that the window, the stopper, or the stopper mounting bracket attached to the shoji frame will be damaged. Since the depth of the stopper receiving groove in the stopper receiver is gradually decreased in the window closing direction, that is, outward from the fire direction side of the opening horizontal frame, if an excessive force is applied as described above, The tip of the stopper comes off from the tip of the stopper along the bottom surface of the inclined groove of the sliding groove.
The vertical sliding window closes immediately, eliminating the risk of damage to the window and stopper device.

The present invention will be described below with reference to illustrated embodiments.

A is a vertical sliding window, and the stopper's axle 4 is vertically slidably fitted into the upper and lower fixing pieces 2 and 3 attached to the vertical stile 1, and the collar piece 5 of the concentric bar 4 and the upper fixing piece 2 are connected to each other. An ammunition machine 6 is interposed between them, and the force of the ammunition machine 6 forces the core body 4 of the stopper to always protrude below the vertical stile 1.

In the figure, 7 is the legitimate child attached to the stem 4 of the stopper, which is the vertical stile 1.
It protrudes toward the indoor side from a vertically elongated slot provided in the.

B is the lower frame of the opening, and as the window A is opened and closed, its vertical stile 1
The tip of the stem 4 of the stopper that protrudes from the bottom of the bottom frame B
A stopper holder C is arranged on the movement trajectory sliding on the top,
When the window A is opened, the tip of the stem 4 of the stopper automatically fits into the receiving groove of the stopper receiver C, and the window A is held in the open position.

Once the stopper shaft 4 is fitted into the receiving groove of the stopper receiver C in this way, the child 7 is operated to pull up the stopper shaft 4 and remove it from the stopper receiver C for the next operation.

Conventionally, in this type of device, the receiving groove of the stopper receiver C was formed in a cylindrical shape with an inner diameter approximately equal to the outer diameter of the stopper stem 4. If this occurs, the window A1 stopper core 4 may be damaged, or the screws for attaching the fixing pieces 2, 3 of the stopper core 4 to the shoji frame 1 may be damaged.

In this case, the depth of the groove is oriented from the lower bottom of the cylindrical stopper receiving groove 8 in the stopper receiver C in the closing direction of the window A, that is, oriented outward from the firing side of the lower frame B. There is a sliding groove 9 at the bottom end of the stopper that gradually decreases, so that when the window A is opened, an excessive force is applied to the window A due to a gust of wind or human power, and an overload is applied to the stopper part. At this time, the stopper shaft 4 slides along the sliding groove 9 from the bottom of the stopper receiving groove 8 in the stopper holder C, and its tip rises, and thus the stopper shaft 4 and the stopper holder C are connected to each other. The engagement is released and window A
will close immediately, and there is no risk that window A and its stopper will be damaged.

Although the illustrated example shows a case where the device of the present invention is disposed on the lower frame side of the opening frame, it may be disposed on the upper frame side.
