Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to a shutter lock.

[Conventional technology]

In conventional shutter locks, the lock lever is raised and lowered by the upward rotation of a lever, and when lowered, the lower end of the lock rod penetrates through a hole in the shutter rail to lock the lock.

[Problem that the invention attempts to solve]

The storm door lock is attached to the final storm door, and since there is a gap between the storm door and the glass door, a thin plate or rod is inserted into the gap, and the tip of the thin plate or rod is inserted at the upper end of the lever. There was a problem in that when the lever was engaged and the thin plate or rod was pressed, the lever could be rotated and unlocked.

[Means for solving problems]

In order to solve the above problems, this invention has the upper end of the rocking plate stacked on the side of the lever rotatably attached to the upper part of the lever, and when the lever is brought down, the edge of the elongated hole The tip of the oscillating plate is brought into contact with the oscillating plate, and the oscillating plate is provided with the ability to rotate in a direction in which the tip thereof rises.

[Effect]

While rotating the lever in the falling direction, the lock rod is lowered, and the lower end of the lock rod is passed through the through hole of the shutter rail to lock the lock.

At this time, the tip of the rocking plate rises as the lever rotates, and when the lever finishes rotating, the tip of the rocking plate comes into contact with the edge of the elongated hole, causing the lever to rotate in the upright direction. Even if an attempt is made to do so, the tension of the rocking plate prevents the door from opening, and the locked state is maintained.

When unlocking, the swinging plate is rotated so that its tip descends, the contact between the tip of the swinging plate and the edge of the elongated hole is released, and the lever is rotated in the rising direction.

〔Example〕

In the figure, A is a shutter lock.

The above-mentioned storm door lock A consists of a mounting lock box 1 and a through hole 2 provided in alignment with the top wall and bottom wall of this lock box 1.
A lock rod 3 that can be raised and lowered is passed through the top wall of the lock box 1, and a long hole 4 is provided in the top wall of the lock box 1 so that one end communicates with the through hole 2. An L-shaped lever 6 is rotatably attached to the lever 6, an L-shaped elongated hole 7 is provided at the lower end of the lever 6, and a pin protrudes halfway from the side of the locking rod 3 so as to pass through the elongated hole 7. 8, and locking and unlocking can be performed while raising and lowering the lock rod 3 by raising and rotating the lever 6.

In addition, a pin 9 is attached to the lever 6 on the side of the lever 6.
The end is attached rotatably through the long hole 4, and the tip that fits into the opposite side of the lock rod 3 of the long hole 4 is inserted into the long hole 4 when the lock is locked.
A rocking plate 10 is provided which comes into contact with the edge of the shaft.

Further, the swing plate 10 described above is provided with the ability to rotate in the direction in which the tip thereof rises.

The above rotatability is achieved by winding a spring rod 11 around the pin 9, and locking one end of the spring rod 11 to the lever 6 and the other end to the rocking plate 10, respectively.

In the figure, reference numeral 12 denotes a piece projecting laterally from the upper edge of the distal end of the rocking plate 10, and the rocking plate 10 is rotated by placing a fingertip on this piece 12. 13 is a mounting piece for the lock box 1. 14 is a stopper piece for preventing the tip of the swing plate 10 from coming off.

〔effect〕

As described above, according to the storm door lock of this invention, the tip of the rocking plate is brought into contact with the edge of the elongated hole during locking, thereby preventing the lever from rotating in the unlocking direction. Therefore, it is possible to prevent the lever from rotating in the unlocking direction due to the operation of the plate, rod, etc.

Therefore, the locked state can be maintained reliably.
