Lock pins for carriage assemblies of printing devices

A carriage assembly for a printing device, the carriage assembly comprising:

• a carriage base to support a printhead;
• a chute assembly attachable to the carriage base, the chute assembly comprising an opening to accommodate the printhead;
• and
• a manifold coupled to the carriage base to cover the printhead;
• a latching device to latch the manifold to the carriage base upon a first downward movement of the manifold towards the carriage base and to unlatch the manifold from the carriage base upon a second downward movement of the manifold towards the carriage base;
• and
• a lock pin slidably mounted on the chute assembly, the lock pin being slideable between a first position and a second position with respect to the manifold, the lock pin to restrict the second downward movement of the manifold towards the carriage base in the second position.

A printing device comprising:

• a carriage assembly to move within the printing device, the carriage assembly comprising:
• a carriage structure defining an opening to house a printhead;
• a manifold positioned above the carriage structure, the manifold to latch with the carriage base upon a first downward movement of the manifold towards the carriage base and to unlatch from the carriage base upon a second downward movement of the manifold towards the carriage base;
• a lock pin slideable on the carriage structure to a first position and a second position respect to the manifold, wherein
• the lock pin is to allow unlatching of the manifold with the carriage structure in the first position and restrict unlatching of the manifold with the carriage structure in the second position;
• and
• a detection pin mounted in the carriage structure, wherein
• in the first position of the lock pin, the detection pin is to engage with the lock pin to restrict a sliding of the lock pin to the second position.
