Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The technology of dummy locks.

[0002]

2. Description of the Related Art Since a key plate cannot be inserted, it is easily recognized as a false lock.

[0003]

SUMMARY OF THE INVENTION A dummy lock that does not rotate even when picked, or that does not release the sound of a cylinder lock, and a dummy lock that cannot be picked are manufactured.

[0004]

Means for Solving the Problems The dead bolt is removed from the fully functioning cylinder lock body, or the cylinder body and the cylinder cylinder on both sides of the shear line of the fully functioning cylinder lock body are connected and fixed. Or, the share line of the fully functioning cylinder lock body was eliminated and the cylinder body and cylinder cylinder were integrated, or
A dummy lock that has the above configuration, with the tumbler of the fully functional cylinder lock body immovably fixed, has a key insertion groove, allows the key plate to be inserted, and cannot be locked.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A dead bolt has been removed from a fully functional cylinder lock body, or a cylinder cylinder and cylinder cylinders on both sides of a shear line of a fully functional cylinder lock body have been connected and fixed, or One or several of the above methods are available, eliminating the share line of the fully functioning cylinder lock body and integrating the cylinder body and cylinder cylinder, or fixing the tumbler of the fully functioning cylinder lock body immovably. A dummy lock that has a key insertion groove and can insert a key plate and cannot be locked.

[0006]

[Embodiment] A completely functioning cylinder lock body has no shear line, the cylinder body and the cylinder cylinder are integrated, a dead bolt is removed from the cylinder lock body, a key insertion groove is provided, a key plate can be inserted, and a key is locked. A dummy tablet that is made into a plate by reducing the thickness of a dummy tablet that cannot be used.

[0007]

According to the present invention, it is possible to produce a dummy lock in which the cylinder body does not rotate even when picked, or the cylinder lock does not release sound.
