Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an automatic sliding door locking device for sliding doors.

Conventional technology For example, as described in Publication of Utility Model Publication No. 54-11426,
One end of the flexible strip is fixed to the upper stile of the shoji,
A pair of insertion arms are protruded from the other end of the main body, which can freely protrude from the rigid frame, and claws provided on the outer surface of the insertion arms are engaged with vertical grooves provided in the rigid frame. Some have a structure in which they are bent so that they protrude from the upper frame and are locked to the upper frame.

Problems to be Solved by the Invention In the conventional example described above, the entire structure is made of a flat plate-like flexible material, and the tip of the insertion arm is used as a doorstop, so the insertion arm collides with the solid frame. At this time, the insertion arm that serves as the doorstop may be bent, making it difficult to insert it into the stile. Due to the flexibility of the main body (easily deformed), the shoji can easily rise due to external forces such as wind pressure and come off the window frame.

Purpose of the Invention The present invention has been devised for the purpose of eliminating the drawbacks of the above-mentioned conventional examples and providing a device that can provide a more reliable retaining state.

Means for Achieving the Object In order to achieve the above object, the present invention provides a guide groove horizontally in the upper stile of the shoji, and engages with the guide groove an operating rod whose tip protrudes freely into and out of the window frame side. , the threaded base end of the operating rod is passed through the upright piece of the sliding frame that is slid into the guide groove, and an adjustment nut is screwed together to connect the operating rod and the sliding frame to each other; The other end of the arm piece has one end rotatably pivoted to the movable frame, and the other end of the locking piece that engages with the guide groove, pivots freely up the shoji upper stile, and locks to the window upper frame. and are pivotably connected to each other.

Embodiment The drawing shows an embodiment of the automatic shoji removal prevention device for a sliding door according to the present invention, where A is a window frame, B is a shoji fitted into the window frame, and the shoji B is formed on the upper side of the upper stile 1. An operating rod 3 is engaged with the guide groove 2, and the operating rod 3 is provided with an L-shaped bent tip 3a, and the tip 3a is arranged on the window jamb 4 side so that it can be moved in and out from the shoji B. The rising piece of the sliding frame 5 is disposed in the groove 2 in a protruding manner and moves the base end 3b of the operating rod 3 laterally along the guide groove 2, on which the male screw a is carved. 5a and screw the adjustment nut 6 to connect the operating rod 3 and the sliding frame 5 to each other, one end of the arm piece 7 is rotatably pivoted to the sliding frame 5 by a pin 16, Further, the other end of the arm piece 7 and one side of the locking piece 8 are pivotably connected to each other by a pin 9, and the other side of the locking piece 8 is fixed to the upper frame 1 at 10. Pivot 1 installed horizontally on the guide frame 11 of the sliding frame 5
2, the bottom piece 5 of the sliding frame 5 is rotatably attached to the guide frame 11, and the bottom piece 5 of the sliding frame 5 is prevented from coming off the edge on the side of the pivot portion 12.
The rise regulating edge 13 is in contact with b, and
A pair of through holes 15, 15 are provided at appropriate locations on the bottom piece 5b of the sliding frame, into which the protrusions 14 provided on the guide frame 11 are fitted to stop the movement of the sliding frame 5.

Therefore, when the shoji B is erected on the window frame A and the shoji B is slid in the direction of the jamb 4, the operating rod tip 3a protrudes from the shoji B and collides with the inner edge 4a of the jamb 4.
The sliding frame 5 is connected to the base end of the operating rod 3 and has a guide frame 11.
, the arm piece 7 rotates around the pin 16, and the locking piece 8 rotates around the pivot 12 to stand up and lock onto the window frame 21. When the tip of the rod 3a is pulled with a fingertip, each member returns to its original position and the shoji B can be removed from the window frame A.

In addition, in the example, a retaining device configured in substantially the same manner as described above was provided on the other side of the window upper frame 21, and male screws a, a were provided at both ends of the sliding frames 5, 5 of each device. They are connected to each other using a connecting rod 17 and adjustment nuts 18, 18, and are configured to be operated by the operating rod 3.

19 shows a guide member for the operating rod 3.

Effects of the invention Since the present invention has the above-mentioned configuration, when the tip of the operating rod collides with the jamb, the sliding frame to which the base end of the operating rod is attached moves along the guide groove.
An arm piece with one end attached to the sliding frame is rotated, and as the arm piece is rotated, the locking piece stands up, automatically preventing the shoji from coming off. This prevents the shoji from rising and coming off due to external forces such as wind pressure.

In addition, the present invention can adjust the length of the protruding length from the guide groove at the tip of the operating rod by moving the adjustment nut forward and backward along the operating rod, thereby reducing the machining accuracy of shoji and window frames or wobbling due to changes over time. can be absorbed and a stable state of preventing the shoji from coming off can be obtained.
