Description

[Detailed description of the invention] This invention relates to a locking device for a double door type door.

For example, to lock a gate with double doors, first lock one door by inserting the tip of a dowel into a hole in the ground using a French drop (gremont), then use a cylinder lock to protrude the lock piece and lock one door. One door is locked to the other.

However, if there is a large gap between the bottom edge of the door and the ground, you can grasp the dropstick and push it up so that the bottom edge escapes the hole, thus locking one door against the ground. Can be canceled.

For this reason, there is a drawback that the engagement between the hole and the protruding lock piece is released when the opposing inner edges of both doors are pushed open.

Therefore, there is a device that prevents the drop bar from being pushed up to solve the above-mentioned drawbacks.

However, the drop rod of this locking device and the lifting rod connected to the drop rod are built into a vertical frame made of pipe on the inner edge of the gate, and have a constant lifting stroke, so the lower edge of the attached gate and the ground The dimensions between them must be constant.

For this reason, there was a drawback that it took time and effort to determine the mounting position of the gate.

The purpose of this invention is to eliminate the above-mentioned drawbacks by making it possible to freely adjust the vertical stroke of the drop bar.

This idea involves inserting a drop bar that can be raised and lowered into a vertical bar made of pipe on the inner edge of one side door, and incorporating a locking device to prevent the drop bar from rising when lowered into the vertical bar. A button for unlocking the drop bar and a photo for raising and lowering the drop bar are provided on the surface corresponding to the vertical frame of the remaining door on one side. To provide a locking device which can be fixed at a predetermined position with a fastener and can change the lifting and lowering stroke of a drop bar.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, A and A' are doors installed in a double-folding style, and at least one of the doors A has a pipe on the inner edge vertical bar 1.

Further, a drop bar 2 that can be raised and lowered upward from the lower end of the vertical beam 1 is fitted, and an upwardly directed lifting rod 3 is connected to the upper end of the drop bar 2.

Further, a through window 4 is provided on the surface of the door A' of the vertical beam 1 facing the vertical beam 1', and a recess 5 provided on the lifting rod 3 is fitted into the through window 4.

Further, a locking device 6 is provided in the vertical bar 1 to prevent the drop bar 2 from rising once it has descended to a predetermined position, and a locking device 6 is provided on the surface of the vertical bar 1 having the above-mentioned through-hole 4 to release the lock. A button 7 is provided.

The above-mentioned locking device 6 includes a slider 8 that slides in the horizontal direction integrally with a button 7 in the illustrated case, a long hole 9 provided in the slider 8 so that the lifting rod 3 passes through it, and a long hole 9 that extends downward from the upper end of the lifting rod 3. As the lifting rod 3 descends, the slider 8 is pushed back while compressing the spring 11 by the edge of the opening 10 and the tapered surface. When the slider 8 is pushed back while pressing the button 7 to compress the spring 11, the locking pawl 12 is removed from the through hole 10. is removed, and the prevention of the lifting rod 3 from rising is released.

Furthermore, the photo 5 provided on the lifting rod 3 is the tightening tool 1.
3 allows it to be fixed at a predetermined position on the lifting rod 3.

The fixing method of the above photograph 5 is as shown in FIGS. 6 and 7, by providing a groove 15 on the surface of the base 14,
After fitting the lifting rod 3 into this groove 15, the base 1
The plate-like body 16 is stacked on the surface of 4, and this plate-like body 16
While fixing the plate-like body 16 to the base body 14 with a fastener 13 consisting of a screw that is inserted into the base body 14 and screwed into the base body 14, the elevating rod 3 is clamped between the base body 14 and the plate-like body 16, and then the plate The recess 18 provided on the back side of the tab 5 is fitted into the protrusion 17 protruding from the surface of the plate 16, and the screw 19 is screwed into the tab 17 from the tab 5 to attach the tab 5 to the plate 16. is fixed.

In the figure, 20 is a through hole provided in the vertical bar 1 for the button 7 to pass through, 21 is a spring that balances the weight of the lifting rod 3 and the drop bar 2, and 22 is a pin 23 attached to the indoor side of the door A, and the end is pivoted. The supported bar plate 24 is a receiving metal fitting attached to the indoor side of the door A' so as to lock the tip of the bar plate 15 into which the bar plate 15 is inserted.

In addition, in the case of illustration, it was attached to a gate, but it may be attached to a door other than a gate.

The locking device according to this invention has the above-mentioned structure, and the locking method will be explained next. First, after closing one door A, the drop bar 2 is lowered together with the elevator lever 3 by shooting 5, and then , the lower end of the drop bar 2 is inserted into the recessed hole B provided in the ground.

At this time, as the lifting rod 3 descends, the through hole 10
The upper edge of the spring 1 and the tapered surface part intermittently
1 is compressed to move the slider 8 backward, and at the same time, the lifting rod 3 is prevented from rising by the locking pawl 12 that fits into the through hole 10 after the drop rod 2 has finished descending.

After that, close the remaining door A′ and open the door above.
The vertical bar 1' of A' covers the photograph 5 of the vertical bar 1 and the button 7.

Note that when closed, the doors A and A' are locked from outside by a cylinder lock and from inside by a bar plate 15 whose tip is locked with a receiving metal fitting 17.

Next, after opening the door A', the button 7 is pushed to allow the locking pawl 12 to escape from the through hole 10, and while maintaining the escape state, the elevating rod 3 is moved together with the drop bar 2 by shooting 5. pull up.

Also, when adjusting the stroke of drop bar 2,
Remove the screw 19 and remove the screw 5, then loosen the fastener 13 and attach the lifting rod 3 to the base 14.
is released, and while lowering the drop rod 2 and the base body 14, when the lower end of the drop rod 2 is inserted into the recessed hole B, the base body 14 is positioned at the lower end of the through-hole 4, and Thereafter, by tightening the fastener 13, the lifting rod 3 is clamped between the base body 14 and the plate-shaped body 16, and the recessed part 18 is fitted into the protrusion 17, and the screw 1 is inserted.
9 fixes the photo shoot 5 to the plate-like body 16.

Furthermore, since the locking pawl 12 is automatically removed from the through hole 10 constituting the locking portion when the lifting rod 3 is lowered, the lifting rod 3 can be lowered smoothly.

Furthermore, when pushing up the lifting rod 3, the button 7 may be pushed to release the engagement between the through hole 10 and the locking pawl 12.

As described above, according to the locking device according to this invention, since the lock can be fixed in a predetermined position of the lifting rod by the fastener, the lock can be loosened by the fastener and the lock can be dropped together with the lifting rod. The lever can be lowered, and the lever can then be fixed in place on the lifting rod by means of a fastener.

Therefore, it is possible to eliminate the inconvenience of having to keep the installation height of the door constant.
