Cylinder lock and method for mounting such a cylinder lock

A cylinder lock comprising:

• a first cylinder housing provided with a first cylindrical recess which extends along a first axis and a second cylindrical recess which extends along a second axis which is parallel to the first axis, wherein both the first and the second cylindrical recess extend from an end of the first cylinder housing, wherein the first cylinder housing is further provided with a first locking pin bore which extends perpendicularly to the second axis and extends partly through the second cylindrical recess, wherein an axis of the first locking pin bore does not intersect the second axis, so that the first locking pin bore is offset with respect to the second axis, wherein the first cylinder housing is provided with an internally threaded locking bolt bore which extends perpendicularly to the second axis;
• a first lock cylinder which in unlocked condition is received rotatably around the first axis in the first cylindrical recess in the first cylinder housing and in a locked condition is received nonrotatably in the first recess;
• a cam which is coupled with or is couplable with the first lock cylinder;
• a bridge which is provided with a central part and a first cylindrical end, wherein the first cylindrical end extends along a bridge axis and is detachably receivable in the second cylindrical recess in the first cylinder housing, wherein the first cylindrical end of the bridge is provided with a single first locking pin recess which extends along a first locking pin recess axis which is perpendicular to the bridge axis and is coaxial with the axis of the first locking pin bore when the bridge and the first cylinder housing are connected with each other, wherein the bridge is provided with a first locking bolt passage which has an axis which extends perpendicularly to the bridge axis;
• a first locking pin which is received in the first locking pin bore in the first cylinder housing and which extends in the first locking pin recess of the bridge when the bridge and the first cylinder housing are connected with each other;
• and
• a first locking bolt with the aid of which the bridge is detachably connected with the first cylinder housing,
• wherein the first locking pin is fixedly received in the locking pin bore, and;
• wherein the first cylindrical end of the bridge is provided with a flattened side which extends at least from a free end, remote from the central part of the bridge, of the first cylindrical end of the bridge up to and including the first locking pin recess, wherein the flattened side extends in a plane that includes an angle with the first locking pin recess axis, such that, upon insertion of the first cylindrical end into the second recess in a first rotational position of the bridge with respect to the first cylinder housing, the first cylindrical end can pass the first locking pin at least in part due to the presence of the flattened side and wherein after complete insertion of the first cylindrical end into the second recess the bridge is rotatable to a second rotational position relative to the first cylinder housing, in which second rotational position the first locking pin is received in the first locking pin recess, such that a displacement of the bridge relative to the first cylinder housing in axial direction along the second axis is hindered, wherein in the second rotational position the first locking bolt passage in the bridge and the first locking bolt bore in the first cylinder housing are oriented coaxially, such that the first locking bolt in assembled condition connects the first cylindrical end of the bridge and the first cylinder housing detachably with each other.
