ABSTRACT:
The present safety mechanism is especially constructed for a carriage insertable into a load space of a vehicle. The safety device prevents the accidental unlocking of wheel supporting, tiltable arms of the carriage. Specifically, the wheel supporting arms must not be able to tilt upwardly unintentionally. For this purpose a security pin or bolt is provided which is capable of reaching behind a shoulder of a locking bolt. The security pin or bolt is connected by a cable to a tiltable lever which supports a roller. When the roller comes to rest on a support, for example, the loading platform, the security pin or bolt is withdrawn from the shoulder arresting position so that only after such withdrawal the locking bolt may be disengaged by actuating a respective grip member at the handle of the carriage.
