Abstract
A lock mechanism to lock two parts relative to each other. The lock mechanism comprises a base plate (30) attachable to one said parts with a pivot pin (26) connected thereto, a keep (38) being defined in the pivot pin. A lock body (24) is also provided and this defines a channel (33) within which the pivot pin locates for rotation of the lock body relative to the pivot pin. A locking arrangement (36) is located within the lock body, and includes a movable bolt (37), which in extended and retracted positions engages with or disengages from the keep (38) to prevent or allow rotation of the lock body relative to the pivot pin. A latch plate (40) may be provided on the other part to cooperate with the lock body. This allows a wide variety of different parts to be secured relative to each other in such a way that they are securely held.
Claims16
A lock mechanism to lock a first part and a second part relative to each other, said lock mechanism having a closed configuration and a open configuration, and said lock mechanism comprising:
- a base plate attachable to the first part;
- a pivot pin secured to the base plate, to prevent movement with respect thereto and having an axis of rotation substantially parallel to the base plate;
- a keep defined in the pivot pin;
- a lock body defining a channel within which the pivot pin is located, said lock body mounted for rotation around the pivot pin and with respect to the base plate, to move between the open and closed configurations;
- and
- a locking arrangement located within the lock body, said locking arrangement including a bolt movable between an extended position and a retracted position, whereby in the closed configuration the lock body and pivot pin are suitably positioned relative to each other such that the bolt may be moved by the locking arrangement to the extended position so as to engage the keep and thus prevent rotation of the lock body relative to the pivot pin, whereas in the open configuration the lock body and pin are not suitably positioned to enable the bolt to engage the keep.
