Abstract
Abstract Described is a latch assembly designed to be affixed to and to secure together two closure members at their abutting edges. A flexible portion of a latch body allows the latch to snap over and then engage a keeper when the edges of the closure members are brought together. For unlatching, a push button actuator is incorporated to cause the flexible element to flex outwardly, thereby releasing the latch from engagement with the keeper and permitting separation of the closure members.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A push button latch comprising, in combination, a latch body and an actuator positioned within said body in operative engagement therewith, said body having front, side and end members, said front member being flexible in a direction substantially perpendicular to the plane of its outer face, an opening formed in said front member, inwardly facing keeper engagement means integral with said front member and spaced apart from said opening, a push button formed toward one end of said actuator and operatively positioned within said opening, whereby inward depression of said push button causes outward motion of the opposite end of said actuator, causing an outward motion of said front member of said latch body.
Claim 2
Dependent Claim
114 words
A push button latch comprising, in combination, a latch body and an actuator positioned within said body in operative engagement therewith, said body having front, side and end members, said front member being flexible in a direction substantially perpendicular to the plane of its outer face, an opening formed in said front member, inwardly facing keeper engagement means integral with said front member and spaced apart from said opening, a push button formed toward one end of said actuator and operatively positioned within said opening, whereby inward depression of said push button causes outward motion of the opposite end of said actuator, causing an outward motion of said front member of said latch body.
Claim 3
Dependent Claim
29 words
The push button latch of claim 1 further characterized by mounting studs projecting from the inner surface of said latch body and adapted to engage openings in a panel.
Claim 4
Dependent Claim
30 words
The push button latch of claim 1 further characterized by spaced apart legs integral with the actuator and positioned for operative engagement with the inner surface of said latch body.
Claim 5
Dependent Claim
24 words
The push button latch of claim 2 further characterized by an opening formed in said actuator through which one of said mounting studs extends.
Claim 6
Dependent Claim
39 words
The push button latch of claim 3 further characterized by a fulcrum edge formed toward the top of the actuator legs, said fulcrum edge providing a pivot contact around which said actuator rotates on depression of said push button.
Claim 7
Dependent Claim
20 words
The push button latch of claim 1 further including cut out portions in the side members of said latch body.
Claim 8
Dependent Claim
73 words
The push button latch combination of claim 1 further characterized by mounting studs attached to the inner surface of said front member at one end and engaging openings in a first panel at the other end, and a keeper having a mounting stud with said mounting stud engaging an opening in a second panel whereby said first and second panels are locked in abutting relationship when said keeper engagement means engages said keeper.
Claim 9
Dependent Claim
37 words
The combination of claim 7 in which the keeper mounting stud is attached to the keeper at a position eccentric to the outside diameter of the keeper thereby providing positional adjustment of the keeper on rotation thereof.
