Cylinder lock and unlocking device comprising thereof

Abstract

An unlocking device has low cost, miniature and simple integral construction, comprising: a cylinder lock(2) operated by the insertion of a matching key; an operating handle(3) producing an unlocking movement for unlocking a door locking mechanism; and a clutch device(4) for transmitting the unlocking movement of the operating handle(3) to the door locking mechanism by an operation of the cylinder lock(2). The cylinder lock(2) includes a first key plug locking mechanism(10) for locking the key plug(8) into the sleeve(7) in the state that the key matching member(9) is inserted into the locking hole(73). The key matching member is arranged with gaps(G1,G2) between an inner surface(73A) of the locking hole(73) and the key matching member(9) in a key insertion and extraction direction in the state that the key plug(8) is locked into the sleeve by the key plug locking mechanism. Consequently, the key matching member (9) can be released smoothly without interference with the inner surfaces(73A) of the locking holes(73).

Description

technical field [0001] The present invention relates to a cylinder lock and an unlocking device provided with the cylinder lock, and more particularly to a cylinder lock for unlocking a door lock mechanism on a vehicle door panel and an unlocking device provided with the cylinder lock. Background technique [0002] As a conventional locking and unlocking device, there is, for example, a device including a clutch (link mechanism for an actuator) that is turned on and off by turning a standard key (matching key) (Patent Document 1). [0003] The locking and unlocking device has: a link mechanism for the handle that generates rotational movement through the pulling operation of the door handle; a lever for the handle that generates a downward linear motion through the rotational movement of the link mechanism for the handle; The linear movement of the rod is transmitted to the above-mentioned actuator using the linkage mechanism of the link mechanism. [0004] In addition, the...

Problems solved by technology

[0009] However, with regard to the locking and unlocking device of Patent Document 1, in addition to the clutch, the cylinder lock, and the handle, it is also equipped with a cylinder lock rod and a key swing lever mechanism, so not only the number of parts is large, but the overall structure is comparatively relatively large. Complicated and costly

[0010] In addition, with regard to the locking and unlocking device of Patent Document 1, since the cylinder lock lever and the key swing lever mechanism are provided between the cylinder lock and the clutch, the external dimensions are relatively large, and there is also a problem with the structure as a whole. The problem of large-scale
