Abstract

A device for locking a detachable roof in a motor vehicle to a vehicle body. The lock device has first and second lock pins caused to appear from or disappear into the detachable roof in synchronism in directions opposite to each other by means of a control lever through first and second levers. These lock pins are inserted into lock holes formed in the vehicle body, whereby the detachable roof is fixed. The lock device further includes: a pawl capable of taking an abutting position where the pawl abuts against at least one of the first and second levers to prevent the levers from being rotated in a direction unlocking the detachable roof, and a releasing position where the pawl is not engaged with the lever; a spring for biasing the pawl in a direction in which the forward end of the pawl abuts against the lever; a release lever made engageable with the pawl only in a direction driving the forward end of the pawl to the releasing position; and a key-locking device having a key cylinder, a key cylinder lever of which can take a locking position where the key cylinder lever prevents the release lever from rocking in a direction driving the pawl and a releasing position where the key cylinder lever does not interfere with the release lever.

A device for locking a detachable roof in a motor vehicle, comprising:

first and second levers rotatably mountable to said detachable rood in contact with each other in a manner to be rotatable in synchronism with each other in directions opposite to each other;
first and second lock pins axially, linearly, movably supportable on said detachable roof by means of guides mounted at positions opposite to each other on said detachable roof and with the first and second levers therebetween, connected to the first and second levers, respectively, through connecting mechanisms, and insertable at forward ends therof into lock holes formed in a motor vehicle body and opposed to the lock pins;
and a control lever connected to one of the first and the second levers to rotate the same, wherein said device further comprises:
a pawl rockingly supported by a rotary shaft, a forward end of which can take an abutting position where the forward end thereof abuts against at least one of the first and the second levers in a locked state in which the first and the second lock pins are projected, so as to prevent the levers from being rotated in a direction unlocking the detachable roof, and a releasing position where the forward end thereof is not engaged with the lever;
a spring for biasing said pawl in a direction in which the forward end of said pawl abuts against the at least one of said levers;
a release lever rockingly journaled and made engageable with said pawl only in a direction of driving the forward end of said pawl to the releasing position;
and
a key-locking device provided contiguously to said release lever and having a key cylinder, said key cylinder having a key cylinder lever which can take a locking position wherein said key cylinder lever abuts against said release lever to prevent said release lever from rocking in a direction of driving said pawl, and a releasing position wherein said key cylinder lever does not interfere with said release lever.
