Abstract

A spring loaded latch assembly including a first stationary member for securement to a desired stationary surface, and a second movable member wherein the assembly provides for controlled reciprocating movement between the two members from a first closed position to a second open position upon pushing engagement by a user. The first stationary member includes a housing, a spring member secured within a portion of the housing by a retaining member and a latch arm connected thereto. The second movable member includes an engagement member in operable communication with the spring member to provide a spring force between the two members and a latch track member for cooperative engagement with the latch arm of the first member. The assembly also includes a release member that enables disengagement of the latch arm from the latch track without causing damage to the first or second members.

Dependent claims

A push-push latch mechanism, comprising:

a first member having a latch arm movably secured by a first end thereof upon a first portion of said first member, and a latch member mounted upon a second end of said latch arm wherein said second end of said latch arm is movably supported upon a second portion of said first member;
a second track member operably connected to said latch member of said latch arm of said first member and comprising a path formed therein for guiding said latch member of said latch arm upon reciprocating sliding movement of said first and second members with respect to each other between a first closed position and a second opened position;
a spring mounted upon said first member and interposed between said first and second members for providing a biasing force between said first and second members so as to relatively bias said first and second members toward said opened position;
means defined upon said second member for retaining said latch member of said latch arm at a predetermined position, along said path, corresponding to said closed position defined between said first and second members when said first and second members are moved with respect to each other from said opened position to said closed position under the influence of a first push force in a first direction opposite to said biasing force of said spring, and yet permitting release of said latch member from said retaining means, so as to permit said first and second members to move with respect to each other from said closed position to said opened position, under the influence of a second push force in said first direction against said biasing force of said spring while said first and second members are retained at said closed position as a result of said latch member being retained by said retaining means;
and
means mounting said second portion of said first member upon said first member for permitting movement of said second portion of said first member and said latch member with respect to said first member for enabling disengagement of said latch member of said latch arm from said retaining means of said second track member when said first and second members are positioned at said first closed position and subjected to a pulling force in a second opposite direction so as to permit said first member and said second track member to be moved with respect to each other to said opened position without causing damage to said first and second members.

3 more elements

A spring-loaded latch assembly, comprising:

a first stationary member having a housing disposed thereon, a spring member disposed within said housing, a latch arm movably mounted at a first end thereof upon a first portion of said first stationary member, and a latch mechanism mounted upon a second end of said latch arm wherein said second end of said latch arm is movably supported upon a second portion of said first stationary member;
a second movable member mounted upon said first stationary member for controlled reciprocating movement with respect to said first stationary member between a first closed position and a second opened position, said second movable member including an engagement member operatively engaged with said spring member of said housing so as to provide a spring biasing force between said first and second members toward said opened position of said second movable member;
a latch track member, defined upon said second movable member for cooperative engagement with said latch mechanism of said latch arm of said first stationary member, comprising a channel formed therein and having a predetermined path for guiding said latch mechanism of said latch arm therein so as to provide said controlled movement between said first and second stationary and movable members, and means for retaining said latch mechanism of said latch arm at a predetermined position corresponding to said closed position of said second movable member, when said second movable member is moved from said opened position to said closed position under the influence of an engagement force applied to said second movable member in a first direction opposite to said biasing force of said spring member, and yet permitting release of said latch mechanism from said retaining means, so as to permit said second movable member to move from said closed position to said opened position, when said second movable member is subjected to an engagement force in said first direction against said biasing force of said spring member while said second movable member is retained at said closed position as a result of said latch mechanism being retained by said retaining means;
and
means mounting said second portion of said first stationary member upon said first stationary member for permitting movement of said second portion of said first stationary member and said latch mechanism with respect to said first stationary member for enabling disengagement of said latch mechanism of said latch arm from said retaining means of said latch track member when said second movable member is positioned at said first closed position and when said second movable member is subjected to a disengagement force in a direction substantially opposite to said engagement force in said first direction so as to permit said second movable member to be moved to said second opened position without causing damage to said first and second members.
