Next, to explain the interlocking lever, gate lock, etc., 4a in the figure is an interlocking bar, and the first interlocking bar 4a is formed by bending a stainless steel plate (SUS430) into a downward U-shape in cross section. It is arranged in the hollow part 96 of the hollow upper stile 24, and is pivoted at the intermediate position between the left and right longitudinal sides of the intermediate upper stile 24 so as to be able to move up and down (4 in the figure).
1) At the same time, its right end portion is disposed directly below the protruding portion 31 of the lever 3, while its left end portion is fitted into the left vertical shaft frame 26 of the gate (see Fig. 2). The first interlocking bar 4a is
By pushing down the lever 3, the right end is pushed down, while the left end is pushed up and rotated exactly like a seesaw (see the double-dashed chain line in FIG. 2). However, the first interlocking bar 4a is
A torsion coil spring 42 provided nearby always biases the lever in a direction that opposes this rotation, and when the downward force of the lever 3 is released, it returns to its original substantially horizontal angle.

On the other hand, 4b in the figure is a second interlocking bar;
The interlocking bar 4b is formed by bending a stainless steel plate (SUS430) into a U-shaped cross section, and is arranged in the hollow part of the left vertical stile 26 of the gate (which is the door stop stile). The upper end of the U-shape is formed by cutting out the bottom of the U-shape, leaving the opposing wall section (4
3) A rotatable round bar roller 44 is installed between both opposing walls of the notch 43, and the left end of the first interlocking bar 42 is loosely inserted into the round bar roller 44 from below. It will come into contact with you. The rotation of the first interlocking bar 4a causes the second interlocking bar 4b to be pulled up via the round bar roller 44, while the lower end of the second interlocking bar 4b is connected to the gate lock 5, which will be described next. (See Figures 8 and 9).

FIGS. 8 and 9 show an embodiment of a gate lock, and the gate lock 5 is provided at the middle of the height of the left vertical stile 26 (which is the door stop stile) of the gate.

First of all, Figure 8 shows an example of a gate lock suitable for a swinging door. In the figure, 51 is a strike (made of SUS304)
2 is a strike receiver (made of SUS304), 53 is a latch (made of brass), 54 is a latch fixing metal fitting (made of SUS304)
The latch fixing metal fitting 54 fixes and holds the latch 53, and the transmission plate 55 (SUS304
The second interlocking bar 4b is pulled up through the rotation of the second interlocking bar 4b to move backward, thereby unlocking the gate. On the other hand, unless a lifting force is applied to the second interlocking bar 4b, the latch 53 and the fixing member 54 maintain the forward locked state due to the bias of the coil spring 56. The strike receiver 52 is provided on the right stile of the other left door 22, which faces the left stile 26.

Next, FIG. 9 shows an example of a gate lock suitable for a sliding gate. In the figure, 57 is a sickle (made of SUS304), and 58 is a torsion coil spring, which is unlocked by pulling up the second interlocking bar 4b. Again, the locked state is maintained by the bias of the spring 58 unless a lifting force is applied to the second interlocking bar 4b. Note that the numbers in the figure that are common to those in FIG. 8 have the same meaning.

By the way, to explain the entire locking/unlocking state of the locking device 1 of the gate, first, the hollow upper stile 2
4 When the lever 3 attached to the top surface is pushed down, the lever 3 rotates downward, and its pushing part 31 pushes down the right end part of the first interlocking bar 4a arranged inside the upper stile hollow part 96. , the first interlocking bar 4a rotates in a seesaw shape around the shaft support 41,
The left end pushes down the round bar roller 44 at the upper end of the second interlocking bar 4b from below, and as a result, the second interlocking bar 4b inside the hollow part of the stile is pulled upwards. The provided gate lock 5 is unlocked.

On the other hand, if no push-down force is applied to the lever 3, the lever 3, the first interlocking bar 4a, the second interlocking bar 4b, and the gate lock 5 are initially Keep locked.

In addition, the gate locking device of the present invention is as follows:
In addition to the illustrated swinging door, it can be used for various gates such as sliding doors, vertically movable gates, and so-called lift-up gates.Of course, it can also be used for combination gates of swinging doors and sliding doors.

Further, the lever of the locking device may be of the vertically movable type as shown, but may also be vertically movable in parallel, and in this case, a coil spring or the like may be selected as the upward biasing means.

Furthermore, the lever can be biased upward not only directly as shown in the illustration, but also indirectly by using a biasing means in an interlocking bar or a gate lock. Good too.

Of course, various types of gate locks can be selected.

In the illustrated example of the gate, only the right door 23 of the left and right doors 22 and 23 is equipped with the locking device 1 of the present invention, but in FIG. This is because the left door is also equipped with a lever of the same quality and shape in order to harmonize the left and right appearance of the gate, and although the lever on the left door can move up and down and is biased upward, It is not linked to the gate lock, and is more of a decorative feature.

Although the embodiments have been configured as described above, it goes without saying that the present invention can be implemented in various ways without departing from the spirit thereof, and is not limited to the above embodiments.

(Effects of the Invention) Since the present invention is configured as described above, it has the following effects.

That is, in the gate locking device of the present invention, a notch opening is transparently provided in the upper surface of the hollow upper stile of the gate, and the notch opening has a vertical movement or a vertical movement that is directly or indirectly biased upward. In addition to installing a freely movable lever,
The lever is linked to the gate lock, and the gate can be unlocked by pressing down on the lever on the top of the upper stile, so simply pushing down on the lever unlocks the gate, so there is no need to use levers or knobs like in the past. There is no need to hold or rotate the handle, making it extremely easy to operate.
