In this auxiliary lock, a locking member holding piece 3 projecting outward is attached to an inward opening type hinged door 1 via an attachment portion 4, and a locking member 5 is attached to the tip end side of the locking member holding piece 3. It is configured to lock by bringing the locking member 5 into contact with the door frame 2 side.

The mounting portion 4 attaches the holding piece 43 to the tip of the screw bolt 42a screwed into the nut 42b arranged on the mounting portion main body 41, whereby the screw bolt 42a is rotated to appear and disappear in the axial direction. The holding piece 43 is moved so that the hinged piece 43 and the locking member holding piece 3 can hold the hinged door 1 and fix the auxiliary lock to the hinged door 1.
The holding piece 43 is composed of a main body portion 43a and a rubber packing 43b.

By the way, in the auxiliary lock of the present embodiment, the locking member holding piece 3 and the mounting portion 4 are configured to be separable on the indoor side, so that the locking member holding piece 3 and the mounting portion 4 are in the locked state when the locking member 5 is in the locked state. 4 and 4 can be separated and unlocked on the indoor side.

As a mechanism for separating the locking member holding piece 3 and the mounting portion 4 on the indoor side, specifically, a cam 44 is arranged on the mounting portion 4 so as to be pullable against the urging force of the spring 45. As shown in FIG. 3A, the mounting portion 4 is attached to the locking member holding piece 3 by engaging the locking portion 44a of the cam 44 with the locking hole 32 formed on the base end side of the locking member holding piece 3. As shown in FIG. 3B, the cam 44 is pulled against the urging force of the spring 45 to integrate the cam 44 with the locking portion 44a of the cam 44 and the locking member holding piece 3. By releasing the engagement with the locking hole 32 formed on the base end side and pulling the hinged door 1 by holding the door knob 6 in this state, the locking member holding piece 3 and the mounting portion 4 are separated on the indoor side. I am trying to be able to do it.

In this case, the pulling operation of the cam 44 is performed by the ring member 46, and the locking member holding piece 3 is operated by the operation method (for example, "open the sliding door of the ring with the emergency escape function to the hinge side"). The instruction sticker 47 stating the above is attached.

Further, the mounting portion main body 41 of the mounting portion 4 is assembled by covering it with the cover 41a.

On the other hand, as shown in FIG. 3, the locking member 5 is formed in the rectangular parallelepiped main body 50 as a locking mechanism on the opposite side of the cylinder lock 51 and the cylinder lock 51, and a slit into which the locking member holding piece 3 is inserted. It has a shaped hole 52, and by inserting the key 54 into the cylinder lock 51 and turning it, a latch ball (not shown) provided in the back of the slit-shaped hole 52 so as to be able to appear and disappear is fixed in a protruding state. It is configured.
Then, the through hole 31 of the locking member holding piece 3 inserted into the slit-shaped hole 52 is locked with a latch ball so that the locking member holding piece 3 can be locked.
In this way, the slit-shaped hole 52 into which the locking member holding piece 3 is inserted is formed in the locking member 5, and the latch ball provided in the back of the slit-shaped hole 52 so as to be able to appear and disappear is fixed in a protruding state. Therefore, the latch ball is not exposed to the outside, which has an advantage that it is difficult to unlock illegally.

Here, in order to lock the locking member 5 by bringing the locking member 5 into contact with the door frame 2 side when the locking member 5 is locked on the locking member holding piece 3, the door frame contact The contact piece 53 is arranged.
The door frame contact piece 53 is provided with a gap adjusting member 53a that adjusts so as to eliminate the gap between the door frame contact piece 53 and the door frame 2 at the time of locking, and the door contact that comes into contact with the surface of the hinged door 1. The contact piece 53b is formed.
Here, by disposing the gap adjusting member 53a, it is possible to prevent the hinged door 1 from rattling during locking.
Further, by forming the door contact piece 53b, the tip portion of the locking member holding piece 3 that has locked the locking member 5 is made difficult to bend toward the hinge side, so that the tip portion of the locking member holding piece 3 is bent to prevent the locking member. It is possible to prevent unauthorized unlocking of 5 to release the contact state with the door frame 2 side.

In this auxiliary lock, when the locking member 5 is in the locked state, the locking member holding piece 3 and the mounting portion 4 can be separated and unlocked on the indoor side, whereby the inward opening type hinged door 1 can be retrofitted. Since it can be used as an auxiliary lock and can be urgently escaped from the room at the time of locking, it can be a highly safe auxiliary lock.
In particular, the locking member holding piece 3 and the mounting portion 4 can be separated and unlocked on the indoor side by a simple operation called a pulling operation, and an emergency escape from the room at the time of locking can be enabled. Therefore, the safety can be further improved.

The auxiliary lock of the present invention has been described above based on the embodiment thereof, but the present invention is not limited to the configuration described in the above embodiment, and the locking member holding piece 3 and the mounting portion 4 are placed on the indoor side. As a mechanism that makes it separable with, for example, a connection structure using a pull-out pin can be adopted, and the configuration can be appropriately changed as long as the purpose is not deviated.

Since the auxiliary lock of the present invention can be used as an auxiliary lock for retrofitting an inward-opening hinged door and enables emergency escape from the room at the time of locking, it can be used as a management lock for an empty room. In addition to being suitably used, it can be widely used as an auxiliary lock for an inward-opening hinged door.
