Abstract
Abstract A retractable latch mechanism including a center body having a cavity therein, the center body being disposed within a frame structure to pivot between an operative position and a nonoperative position. The mechanism also includes a pintle member which has a latch portion at one end thereof and is disposed through a bore in a guide member, the pintle and guide guide members being movable through an opening in the frame structure between a retracted position within the center body cavity and a raised position partially through the frame opening when the center body is in the operative position. When the pintle and guide members are in the raised position the center body may be pivoted to its non-operative position to lock the mechanism in the raised position and the pintle member may be pivoted between an unlatched position and a latched position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
155 words
A retractable latch mechanism comprising: a frame support having a first side and a first opening through said first side, a center body having a cavity therein, said center body disposed on one side of said first side and pivotal about an axis substantially perpendicular to said first side between an operative position and a non-operative position, a guide member having a bore therethrough, said guide member movable in said first opeNing between a retracted position within said cavity and a raised position partially through said first opening when said center body is in said operative position, and a pintle member disposed through said bore and having a latch portion at one end thereof, said pintle member being movable with said guide member between said retracted position and said raised position and also being pivotal within said bore between an unlatched position and a latched position when said guide member is in said raised position.
Claim 2
Dependent Claim
155 words
A retractable latch mechanism comprising: a frame support having a first side and a first opening through said first side, a center body having a cavity therein, said center body disposed on one side of said first side and pivotal about an axis substantially perpendicular to said first side between an operative position and a non-operative position, a guide member having a bore therethrough, said guide member movable in said first opeNing between a retracted position within said cavity and a raised position partially through said first opening when said center body is in said operative position, and a pintle member disposed through said bore and having a latch portion at one end thereof, said pintle member being movable with said guide member between said retracted position and said raised position and also being pivotal within said bore between an unlatched position and a latched position when said guide member is in said raised position.
Claim 3
Dependent Claim
76 words
A retractable latch mechanism as specified in claim 1 wherein said centerbody has an aperture therein in communication with said cavity, said aperture having a shape selected relatively to the shape of said guide member to provide means for allowing said guide member to move through said aperture when said centerbody is in said operative position and for not allowing said guide member to move through said aperture when said centerbody is in said non-operative position.
Claim 4
Dependent Claim
69 words
A retractable latch mechanism as specified in claim 2 wherein a portion of said guide member remains within said first opening when said guide member is in said raised position and wherein the shape of said first opening is selected relative to the shape of said guide member to limit the rotation of said guide member relative to said frame when said pintle member is pivoted within said bore.
Claim 5
Dependent Claim
25 words
A retractable latch mechanism as specified in claim 3 and including means for maintaining said guide member adjacent said latch portion of said pintle member.
Claim 6
Dependent Claim
65 words
A retractable latch mechanism as specified in claim 4 wherein said frame support includes a second side apart from said first side, said center body being disposed between said first and second sides and said second side having a second opening therein, said pintle member passing through said second opening, said cavity, and said first opening when said pintle member is in said raised position.
Claim 7
Dependent Claim
34 words
A retractable latch mechanism as specified in claim 5 and including means for limiting the movement of said pintle member through said first opening as said pintle member is moved toward said raised position.
Claim 8
Dependent Claim
38 words
A retractable latch mechanism as specified in claim 6 wherein said means for limiting is a washer connected to said pintle member and adapted to abut said second side when said pintle member is in said raised position.
Claim 9
Dependent Claim
39 words
A retractable latch mechanism as specified in claim 7 and including means for moving said guide member and said pintle member between said retracted position and said raised position and for pivoting said pintle member between said unlatched position.
Claim 10
Dependent Claim
32 words
A retractable latch mechanism as specified in claim 8 and including means for securing said center body in said non-operative position and means for securing said pintle member in said latched position.
