Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a slide bar automatic lock device for a skylight shoji.

[Prior Art] In a skylight installed in a building, there is a skylight that can be opened not only by simply opening and closing it but also by sliding it in parallel.

This kind of skylight has an opening / closing device for opening / closing the skylight shoji and a slide device for moving the skylight shoji in parallel, and normally only the opening / closing device is operated to rotate the skylight shoji around the hinge, but the skylight is opened. In case of cleaning the outer surface of the skylight shoji, the sliding device can be operated to move the skylight shoji in parallel.

When the skylight shoji slides, the set screw a of the slide device is loosened as shown in FIG.
When the opening / closing lever c having the tip fixed with a screw is tilted backward after the connection with the slide bar b is pushed, the slide bar b is pushed rearward while the opening angle of the skylight shoji d gradually narrows. As shown in the figure, the skylight shoji d can be slid behind the window frame f together with the hinge e attached to the tip of the slide bar b.

[Problems to be Solved by the Invention] In the skylight described above, the set screw a of the slide bar b must be loosened when the skylight shoji d is slid,
The work was tedious.

The present invention has been made to solve such conventional problems, and the slide bar can be automatically unlocked when the skylight shoji slides, and further, the self-lock can be performed when the skylight shoji is returned. It is a technical object to provide an automatic locking device.

[Means for Solving the Problem] As a means for solving this technical problem, the present invention is slidably attached to a window frame, provided with an inclined surface and a locking portion at its tip, and has a rear portion. A slide bar having a skylight shovel attached to the end via a hinge, a lock pin that engages with the inclined surface and engages and disengages with the locking portion, a rotating lever that moves the lock pin in its axial direction, and the skylight. Attached to the chain that drives the shoji,
The gist of the present invention is to have a slide plate that engages with the rotation lever.

[Operation] When the skylight shoji slides, the slide plate moved by the drive chain rotates the rotation lever and the lock pin is retracted to unlock the snow ride bar, and the skylight shoji slides while the skylight shoji is returned. Occasionally, the inclined surface at the tip of the slide bar advances while pushing away the lock pin, and when the inclined surface passes, the lock pin is pushed in, locked by the locking portion of the slide bar, and automatically self-locked.

Embodiment Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiment.

In FIG. 1, reference numeral 1 denotes a slide bar slidably provided with respect to the window frame 2, and an inclined surface 1a is formed at a tip thereof, and a stepped locking portion 1b is provided subsequently to the inclined surface 1a.
As shown in FIG. 2, a hinge 4 is attached to the rear end portion via a mounting bracket 3. The slide bar 1
A roller 1c for lateral shake prevention and a roller 1d for vertical shake prevention are attached to the window frame 2 and the roller 1c.
By rolling along the left and right walls and the upper and lower walls of the guide tube 5 having a rectangular cross section inside, the slide bar 1 can slide smoothly inside the guide tube. Numeral 6 is a substantially L-shaped plate-shaped rotary lever, which is located at the tip of the guide cylinder 5 and is positioned on the window frame 2
Is attached to the inner side of the shaft via a mounting member 7 and a shaft 8 and is urged clockwise by a coil spring 9 wound around its supporting shaft in FIG. A lock pin 10 is slidably fitted to a sleeve 11 fitted to the side wall of the guide cylinder 5, and its rear end is supported by an inner end of the rotary lever 6 by a shaft 12. There is. 13 is a slide plate,
As shown in FIG. 3, a plurality of rollers 13a attached to the lower end portion of the side surface are attached so as to be rollable along a pair of upper and lower guide rails 2a formed on the window frame 2, and substantially the middle portion is It is fixed to the drive chain 14 and can be slid back and forth by this drive chain. In addition, the front end surface of the slide plate 13 has a piece
15 is fixed, and this piece is made to rotate by pushing the end portion of the rotary lever 6.

In FIG. 3, reference numeral 16 denotes an opening / closing lever for the skylight shoji 17, which is actuated by the drive chain 14 as in the conventional case. Further, in FIG. 1, reference numeral 18 is a drive shaft, and the drive chain 14 is wound around a sprocket 19 attached to the end thereof.

The lock device of the slide bar according to the present invention is configured as described above, and when the skylight shoji 17 is opened, the drive chain is
The opening / closing lever 16 is raised via the slide plate 13 and the slide plate 13, and the slide plate 13 is moved forward (to the left in the drawing) as shown in FIG. 1 as the drive chain 14 moves. When the skylight shoji is fully opened, the piece
15 rotates the rotary lever 6 counterclockwise against the coil spring 9 and pulls the lock pin 10 to unlock the slide bar 1.

After that, the upper end of the opening / closing lever 16 is fixed, and the skylight shoji 17 is slid down by gradually tilting it backward. At this time, since the lock of the slide bar 1 has already been released, the slide bar is moved to the guide. It is moved rearward (to the right in FIG. 1) along the tube 5. This movement causes the slide plate 13 to also retract, so that the rotary lever 6 is rotated clockwise by the restoring force of the coil spring 9,
The lock pin 10 projects into the guide cylinder 5. In this way, the skylight shoji 17 can be slid rearward, with the opening angle thereof being gradually reduced, as in the conventional case.

Next, to return the skylight shoji 17 to its original state, open and close the lever for opening and closing.
16, the slide bar 1 moves forward in the guide tube 5 (leftward in FIG. 1) at this time, and at the final stage, the inclined surface 1a of the slide bar 1 moves to the lock pin.
10 is gradually pushed away, the rotary lever 6 is advanced while being rotated counterclockwise, and when the inclined surface passes, the lock pin 10 is pushed by the restoring force of the coil spring 9 and locked to the locking portion 1b. , It is designed to automatically self-lock.

After this, the set screw of the opening / closing lever 16 is loosened and tilted rearward again to move to the closing operation of the skylight shoji 17, but at this time, since the tip end of the sillado bar 1 is already locked by the lock pin 10, it slides. The bar does not move rearward (rightward in FIG. 1) along the guide tube 5, and the skylight shoji can be closed.

In a normal opening / closing operation of the skylight shoji 17, since the slide bar 1 is kept in the locked state by the lock pin 10, the slide bar does not move even if the opening / closing lever 16 is tilted backward when closing the skylight shoji. , There is no hindrance to the closing operation.

[Effects of the Invention] As described above, according to the present invention, the lock of the slide bar is automatically released when the skylight shoji slides, and when the skylight shoji is returned, the lock pin is locked by using the return operation of the slide bar. Since it is configured so that it can be pushed out and self-locking automatically, it is not necessary to manually operate the set screw of the slide bar as in the conventional case, and the effect of sliding the skylight shoji can be achieved very easily.
