[0004] However, in the device disclosed in the aforementioned Patent Document 1, since the member that holds the shutter at the open position is configured to move along the axis of the keyhole, the housing becomes large in size along the axis of the keyhole. Along with this, it is necessary to form the mechanical key into a very long

Abstract

In the protector of a cylinder lock arranged such that a shutter plate is reset automatically from open position to closed position as a mechanical key is withdrawn from a key hole, a spring means (57), first and second engaging members (58, 59), and a cam means (60) for operating the engaging members are housed in a casing (22) to operate along a plane intersecting the axis of a key hole (28) perpendicularly. The cam means makes the first engaging member (58) engage with the shutter plate (34) in response to operation of the shutter plate to the open position, makes the second engaging member (59) engage with the shutter plate in response to insertion of the mechanical key (33), disengages the first engaging member from the shutter plate in response to rotary operation to the on position, and disengages the second engaging member from the shutter plate in response to withdrawal of the mechanical key. Since the mechanical key is not required to be formed long, the protector of a cylinder lock can be constituted compactly.

Description

technical field [0001] The invention relates to a protection device for a cylinder lock. The protection device for a cylinder lock comprises: a housing which has an insertion hole and is fixed to a cylinder body of the cylinder lock. The insertion hole corresponds to a keyhole, and the keyhole is arranged on an inner cylinder that the cylinder lock has; a gate that can move along a plane perpendicular to the axis of the keyhole between a closed position that closes the insertion hole and an open position that opens the insertion hole, And the gate is accommodated in the housing; and a magnetic lock capable of holding the gate in the closed position when locked, and locking the gate from the closed position to the closed position when unlocked. Operated in an open position, the gate is automatically reset from the open position to the closed position as the mechanical key is withdrawn from the keyhole. Background technique [0002] For example, in Patent Document 1, there is...
