Description

[Detailed description of the invention] This invention allows the user to operate a rotary handle mounted on the outer seat of one of a pair of gates, which is integrally connected to the rotary handle and provided on the inner seat of the gate. This invention relates to a gate lock in which a locking rod is removably engaged with a locking member provided on an inner seat of an opposing gate, and in particular, the inner seat of one of the gates is provided with the rotary handle and the locking member. The locking rod is rotatably supported via a square core rod, and the inner seat of the square core has a parallel end surface, while a slide is operated against the inner seat by the cam mechanism of the key. The movable plate is provided with a perforated part that allows the inner seat part of the square core rod to rotate freely, and a lock hole is perforated on one side of the perforated part in the parallel end surface part and the retaining part. When the parallel end surface portion is located in the drilled hole, the rotating handle and the locking rod can freely rotate, and when the parallel end surface portion is engaged with the locking hole, the rotating handle and the locking rod can rotate freely. Rotation of the rod is restrained and the rod is locked so that it cannot rotate, while a protrusion of the stopper that engages with the cam mechanism of the key and can be restored is engaged with a pair of grooves provided in the sliding plate. The present invention relates to a gate lock in which the displacement of the sliding plate is restrained, and the sliding plate is caused to flip-flop through the key.

Conventionally, by operating a rotary handle that is loosely fitted to the outer seat of one of the gates as a gate lock, a locking rod connected to the rotary handle and provided on the inner seat of the gate can be locked inside the opposite gate. Gate locks were used that were designed to lock and release with a hook as a locking member provided on the seat, and were locked with a small lock such as a padlock as needed.

However, using a separate small lock as described above means that the lock must be engaged with the retaining part each time the gate is locked.
When using the gate, remove the lock from the engaging part,
There is a drawback that it requires complicated management such as storing the lock,
Additionally, separately providing the above-mentioned small lock on a gorgeous and elegant gate has the disadvantage that it impairs the aesthetic design of the gate.

In view of the problems with the gate lock based on the above-mentioned conventional technology, the purpose of this invention is to eliminate the above-mentioned drawbacks by providing a lock on the inner seat of the gate, and to solve the problems and to create a simple structure based on a rational design. The aim is to provide a new gate with excellent functionality.

The structure of this invention in accordance with the above purpose is that, by rotating a rotary handle loosely fitted to one outer seat of the gate, a locking lever connected to the rotary handle and provided on the circular seat of the gate is operated. is engaged with the locking member provided on the circular seat of the opposing gate,
On the other hand, when the key is inserted and rotated into the locking hole provided in the circular seat of one of the gates, the rotation of the square core rod that pivotally supports the rotating handle and the locking rod prevents the stopper from moving against the sliding plate. The gist of the present invention is that the locking lever is restrained by the locking member, and the engagement of the locking rod with the locking member is locked.

Next, an embodiment of this invention will be described below based on the drawings.

Reference numeral 1 denotes a gate lock which is the gist of this invention, and the gate lock 1 is attached as a pair to opposing parts of well-known gates 2 and 2' of the double-opening type when the gates are closed.

That is, at a predetermined inner position of the one gate 2, an outer seat 3 and a circular seat 4, which are appropriately designed die-cast molded products and have the same shape, sandwich the gate on the inside and outside of the gate 2, respectively. The outer seat 3. A square core rod 5 is rotatably inserted and supported in the center of the inner seat 4, and a rotary handle 6 is appropriately drawn and fixed on the external pressure 3 side of the square core rod 5. On the side of the circular seat 4 of the square core rod 5, a locking rod 7 with a tip end is fixed integrally and perpendicularly to the square core rod 5, so that when the rotating handle 6 is rotated, The locking rod 7 is configured to rotate along with the rotation of the rotating handle 6 via the square core rod 5.

Reference numeral 8 denotes a key portion, which has the function of restraining the rotation of the square core rod 5, and is provided on the circular seat 4 side of the square core rod 5.

That is, on the circular seat 4 side of the square core rod 5, a square shaft 9 as a parallel end surface is formed perpendicular to the locking rod 7, and a sliding plate 10 slides perpendicularly to the square shaft 9. The sliding plate 1
0 is provided with a circular hole 11 as a bored portion through which the square shaft 9 of the square core rod 5 can rotate freely, and a parallel end surface of the square shaft 9 and a parallel end surface of the square shaft 9 are formed on the vertically downward side of the circular hole 11. A rectangular hole 12 is drilled in the close abutting engagement, and when the sliding plate 10 slides to the lower end, the square shaft 9 is located in the circular hole 11 of the sliding plate 10, and the square shaft 9 becomes freely rotatable, so that the rotating handle 6 and the locking rod 7 are freely rotatable, while when the sliding plate 10 slides to the upper end, the square shaft 9 moves into the rectangular shape of the sliding plate 10. The square shaft 9 is fitted into the hole 12 and cannot be rotated, so that the rotating handle 6 and the locking rod 7 maintain the horizontal state of the locking rod 7.

The sliding plate 10 forms a predetermined shape of a flat plate as shown in FIG. 14 and a protrusion 17 of the key 16 shown in FIG. 4 on the lower end surface 15.
A hole 18 is formed in the bottom plate 19 of the key part 8, in which the tip of the key 16 engages so as to be able to come into contact with the key. 16 is inserted, and when the key 16 is rotated clockwise, the protrusion 17 of the key 16 comes into contact with the lower end surface 15 of the letter-shaped notch 13 of the sliding plate 10, and the sliding plate 10 is slid upward. When the key 16 is rotated to the left, the protrusion 17 of the key 16 engages with the letter-shaped notch 13 of the sliding plate 10.
The sliding plate 10 contacts the lower end surface 15 of the sliding plate 10 so as to slide downward.

A groove 21 in the shape of a letter is cut in the center of the sliding plate 10, and a stopper 23 having a protrusion 22 that slides into the groove 21 is rotated around a pin 25 by a spring 24. The protrusion 17 of the key 16 is provided in such a way that it can be restored, and when the key 16 is rotated to the right in the figure, the protrusion 17 of the key 16 engages the R part of the stopper 23 on the lower surface of the letter-shaped notch 13 carved in the lower part of the sliding plate 10. 2
6, the stopper 23 is rotated to the left about the pin 25 against the spring 24, and the protrusion 22 of the stopper 23 is inserted into the [shaped groove 21 formed in the center of the sliding plate 10].
As the key 16 is removed from the upper groove 27, the protrusion 17 of the key 16 comes into contact with the upper end surface 14 of the letter-shaped notch 13 provided at the lower part of the sliding plate 10, and slides the sliding plate 10 to the upper end. When the protrusion 17 of the key 16 finishes turning, the stopper 2
The protrusion 17 of the key 16 is released from being pressed against the R portion 26 of No. 3, and the stopper 23 is pressed against the pin 2 by the spring 24.
5, the protrusion 22 of the stopper 23
is slidably engaged with the lower groove 28 of the letter-shaped groove 21 in the center of the sliding plate 10, and the downward sliding of the sliding plate 10 is stopped.

On the other hand, a circular seat 4 and a hook 29 as a locking member are fixedly installed inside the opposing gate 2' at a predetermined position, and the above-mentioned locking rod 7 is adapted to engage and separate from the hook 27. A handle 30 having the same shape as the rotary handle 6 provided on the outer seat 3' and the gate 2 is fixed symmetrically to the rotary handle 6 at the same predetermined position as the rotary handle 6.

In the above configuration, when locking the gates 2, 2',
The gates 2 and 2' are each closed, and the lock rod 7, which is facing downward due to its own weight, is manually rotated to the left parallel to the gate 2 and 2', and the lock is closed. Attach the lock lever 7 to the hook 27 above.
When the key 16 is locked into the locking hole 20 and the key 16 is rotated clockwise, the protrusion 17 of the key 16 is also rotated clockwise, causing the protrusion 17 to slide downward. The stopper 23, which is close to the R part 26 of the stopper 23 on the lower surface of the [character-shaped notch 13 of the plate 10 and the [character-shaped notch 13], contacts the R part 26, and has the R part 26, The stopper 23 is rotated to the left in the figure against the spring 24 which applies a restoring force to the center, and the upper groove 27 of the [shaped groove 21]
Printed on.

While the protrusion 22 of the stopper 23 that had been in dynamic engagement moved from the right end to the left end of the upper groove 27 and maintained that state, the sliding plate 10 slid over the length of the [shaped groove 21]. It has a dynamic stroke and is able to slide upward.

Thus, the protrusion 17 of the key 16 comes into contact with the upper end surface 14 of the letter-shaped notch 13, causing the sliding plate 10 to slide upward, and the protrusion 22 of the stopper 23
The sliding plate 10 is also relatively slidably engaged with the vertical groove 21 in the central portion of the sliding plate 10, and the sliding plate 10 is slidably engaged with the vertical groove 21 in the central portion of the sliding plate 10 until the protrusion 22 is positioned in the lower groove 28 of the character-shaped groove 21. When the plate 10 continues to slide upward and stops at this position, and the protrusion 17 of the key 16 is located substantially upward as shown in FIG.
7 is detached from the R portion 26 of the stopper 23, and the stopper 23 turns to the right due to the restoring force of the spring 24, and the protrusion 22 of the stopper 23 is located above the lower groove 28 of the [shaped groove 21]. When engaged with the right end, the sliding plate 10 becomes unable to slide downward.

On the other hand, with the above-mentioned locking rod 7 locked to the above-mentioned hook 29, the side surface of the above-mentioned square shaft 9 as a square core rod is vertically fitted into the rectangular surface of the above-mentioned rectangular hole 12 as the above-mentioned lock hole. When engaged, the square shaft 9 becomes unable to rotate, so that the locking rod 7 is engaged with the hook 29 and becomes locked, and the gate 2° 2' is locked.

In addition, when unlocking the gates 2, 2',
Contrary to the case of locking ', the key 16 is inserted into the locking hole 2.
0 and rotate the key 16 to the left, the lock will be unlocked by reversing the process described above.

Note that the embodiments of this invention are not limited to the above embodiments,
It is of course possible to make the square core rod into a hexagonal shaft like a hexagonal bolt, and the drilled part is not limited to a circular hole, but can also be an elliptical hole. It is also possible to remove the lock hole and make the lock hole concave.Furthermore, by providing a lock hole in the external pressure part, it is also possible to lock the gate from inside and outside.

Furthermore, the application target is not limited to gates, but can also be applied to fence locks, etc.

As mentioned above, according to this invention, a lock part is also provided on the rotary handle and the locking rod of one of the gates through the square core rod, and the square core rod engages inside the flip-flop. The gate can be easily locked at the key, and it is extremely convenient to only need to manage the key.

Further, the key part has an extremely simple structure consisting of the square core rod, a sliding plate having a lock hole that releasably engages with the square core rod, and a stopper that maintains the flip-flop state of the sliding plate. Because of this, the above-mentioned key maintains its function as a lock even in the face of wind and rain, and can be used for a considerable period of time. Even if you try to open a locked gate,
No stress is generated in the key portion, and an excellent effect is achieved in terms of maintenance.

Furthermore, both the sliding plate and the stopper that make up the key are flat, so the key does not take up a large installation space and can be inserted into the inner seat of the gate, so it can be decorated as appropriate. By providing a die-cast circular seat and an external pressure having the same shape as the circular seat, the circular seat of the opposing gate, and the external pressure, there is an advantage that the gate as a whole can have a design effect.

In addition, by rotating the key, the stopper is rotated around the pin, and the protrusion of the stopper is separated from the letter-shaped groove of the sliding plate. The rectangular hole in the moving plate can be locked in correspondence with the parallel end surface, and compared to systems that use a rack and pinion, the rotation of the key is directly converted to locking the parallel end surface, resulting in efficient operation. Not only does this provide an excellent effect of locking the lock, but also the protruding portion of the stopper prevents the sliding plate from returning to the unlocking direction, resulting in an excellent effect of reliably locking the lock.

Therefore, since there is no waste in operation, there is little wear and tear, and functional constancy is maintained, which results in an excellent effect of fewer failures.
