Patent ID: 7367597

Claim:
A push-to-open latch selectively moveable between latched and unlatched positions along a latch axis, the push-to-open latch having opposing proximal and distal ends, the push-to-open latch comprising: a latch assembly, including: a latch housing having a housing bore open at the proximal end and extending along the latch axis to a housing bottom wall at the distal end; and a pin rod shaft extending upwardly from the housing bottom wall along the latch axis and having a pin rod dowel extending laterally outwardly from the pin rod shaft at the proximal end; and a catch assembly reciprocatively moveable relative to the latch assembly along the latch axis and including: a catch housing having a catch bore aligned with the latch axis; an inner cam axially rotatably disposed within the catch bore and having a mating end and a bearing end facing the proximal end, the mating end having inner cam mating end ramps formed thereon; and an outer cam axially rotatably disposed within the catch bore and having a mating end and a bearing end, the mating end having outer cam mating end ramps formed thereon, the bearing end facing the pin rod shaft, the inner and outer cam mating ends collectively defining a cam interior, the outer cam having a cam bore extending axially therethrough for passage of the pin rod shaft; wherein the inner and outer cam mating end ramps cooperate to alternately engage and release the pin rod dowel from the cam interior such that the push-to-open latch is respectively placed in the latched and unlatched positions during reciprocation of the pin rod shaft through the cam bore along the latch axis.
