Abstract

This cylinder lock is a cylinder lock which can lock and unlock a mortise lock via a displacement transmission member. The cylinder lock comprises: a cylinder lock body; a key insertion part which is provided on one end side of the cylinder lock body and into which a key is inserted; and a displacement transmission member mounting part which is provided on the other end side of the cylinder lock body and on which the displacement transmission member can be mounted. A plurality of displacement transmission members corresponding to each of case locks having a plurality of specifications can be removably mounted on the displacement transmission member mounting part. Thus, cylinder locks having the same specification can be applied to case locks having a variety of specifications.

First claim

1 . A cylinder lock configured to lock and unlock a mortise lock via a displacement transmission member, the cylinder lock comprising:
a cylinder lock body; a key insertion portion that is disposed at one end of the cylinder lock body and allows a key to be inserted therethrough, and a displacement transmission member mounting portion that is disposed at another end of the cylinder lock body and is provided for allowing mounting of the displacement transmission member, wherein the displacement transmission member mounting portion allows each of a plurality of displacement transmission members to be detachably mounted thereon, the plurality of displacement transmission members respectively corresponding to mortise locks having a plurality of types of specifications.

2 . The cylinder lock of claim 1 , further comprising:
a cylinder cover mounting portion that is disposed at the one end of the cylinder lock body and is provided for allowing mounting of a cylinder cover, wherein the cylinder cover mounting portion allows each of a plurality of cylinder covers having a plurality of types of specifications to be detachably mounted thereon.

3 . The cylinder lock of claim 1 , further comprising:
a keyhole that is continuous with the key insertion portion, wherein the keyhole is suitably applicable to each of a plurality of the cylinder locks that are different in an axial length of the cylinder lock body.

4 . A set of cylinder locks comprising a plurality of the cylinder locks of claim 1 ,
wherein the plurality of the cylinder locks have an identical inner structure in proximity to the other end while being different in an axial length of the cylinder lock body, and wherein the set of cylinder locks include a key of an identical type that is suitably applicable to all of the plurality of the cylinder locks different in the axial length of the cylinder lock body.

5 . The cylinder lock of claim 2 , further comprising:
a keyhole that is continuous with the key insertion portion, wherein the keyhole agrees with each of a plurality of the cylinder locks that are different in an axial length of the cylinder lock body.

6 . A set of cylinder locks comprising a plurality of the cylinder locks of claim 2 ,
wherein the plurality of the cylinder locks have an identical inner structure in proximity to the other end while being different in an axial length of the cylinder lock body, and wherein the set of cylinder locks include a key of an identical type that agrees with all of the plurality of the cylinder locks different in the axial length of the cylinder lock body.

7 . A set of cylinder locks comprising a plurality of the cylinder locks of claim 3 ,
wherein the plurality of the cylinder locks have an identical inner structure in proximity to the other end while being different in an axial length of the cylinder lock body, and wherein the set of cylinder locks include a key of an identical type that agrees with all of the plurality of the cylinder locks different in the axial length of the cylinder lock body.
