DEFINITION

Classification: 24/615

Requiring manual force applied against bias to interlock or disengage:

(under subclass 614) Projection wherein the resiliently biased component or segment is intended to be moved either into or out of its normal interlocking position by manual force applied directly to the biased component or segment in a direction opposite to that of the biasing force.

(1) Note. To be proper for this and the indented subclasses it is required that the direction of this manual force for moving the resiliently biased component or segment be always applied at an angle to the direction of travel of the projection member during its final stage of association with the receiving member.
