Snap lock connector for components such as knock-down furniture components

A snap lock connector for use in connecting and disconnecting components, such as furniture components, and being characterized by a rigid construction which provides longitudinal stabilization of the components in the locked condition by preventing relative longitudinal movement or pivoting between the components;

• said connector comprising:
• an elongate male member for forming an extension from one of the components to be assembled and having a generally bulbous outer end defining opposing, curved, oppositely and outwardly extending, leading and trailing, camming surfaces generally around at least a portion of the circumference thereof, a longitudinally extending intermediate portion extending from said trailing surface and being of smaller transverse cross-sectional dimensions than said bulbous outer end, and a generally non-flexible rear end portion extending longitudinally from said intermediate portion and being of a predetermined configuration having cross-sectional dimensions at least as large as said bulbous outer end;
• a female member for forming an elongate, internal passageway within the other of the components to be assembled and having an inner portion of slightly larger dimensions than said bulbous outer end of said male member, and inwardly and longitudinally extending projection forming an intermediate portion for restricting the dimensions of said passageway at said intermediate portion to less than the dimensions of said bulbous outer end of said male member, and a longitudinally extending generally non-flexible outer portion of slightly larger dimensions than said bulbous outer end of said male member, and being of a predetermined configuration corresponding generally to the predetermined configuration of said rear end portion of said male member for snuggly receiving same when said members are in locking engagement, said projection defining opposing, curved, oppositely and inwardly extending, leading and trailing, camming surfaces;
• one of said male and female members comprising flexible, resilient material and having a longitudinal cut-out partially therethrough for rendering a portion other than said generally non-flexible portion of said one member expandable and contractable;
• and
• said leading, camming surface of at least one of said male and female member comprising a lesser included angle with respect to a longitudinal axis than said trailing camming surface for locking of said members with less force than unlocking of said members;
• whereby, said male member may be inserted into and withdrawn from said female member for locking of said members by forced sliding engagement of said leading camming surfaces and for unlocking by forced sliding engagement of said trailing camming surfaces of said male and female members causing flexible contraction of said expandable and contractable portion of said one member for allowing passage of said bulbous outer end of said male member past said projection in said intermediate portion of said female member, and so that, when said male member is inserted into said female member and is in locking engagement therewith, said trailing camming surface of said male member will be in engagement with said trailing camming surface of said female member and said generally nonflexible rear end portion of said male member will be snuggly received in said generally non-flexible outer portion of said female member of generally the same configuration for providing a rigid connection with longitudinal stabilization of said male and female members to prevent relative movement or pivoting between said members and thus the components being connected.
