Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
176 words
A locking mechanism comprising: a. a stationary structure having a movable structure extensibly mounted thereon; b. pivot means fixedly attached on one end thereof to said stationary structure and having a tongue movable into juxtaposed relationship to a surface of the movable structure, the tongue having an aperture formed therethrough; c. a housing mounted on the movable structure and having bore formed therein, said housing positioned so that the aperture of the tongue of said pivot means is axially alignable with the bore thereof, said housing having a slot formed therein transverse to its bore and opening thereinto; d. a plunger axially insertable through the apreture of the tongue of said pivot means and into the bore of said housing, said plunger having a groove therein which aligns with the slot of said housing when said plunger is inserted therein; and e. locking latch means mounted on the movable structure and retractably movable through the slot of said housing into the groove of said plunger for releasably retaining said plunger within the bore of said housing.
Claim 2
Dependent Claim
176 words
A locking mechanism comprising: a. a stationary structure having a movable structure extensibly mounted thereon; b. pivot means fixedly attached on one end thereof to said stationary structure and having a tongue movable into juxtaposed relationship to a surface of the movable structure, the tongue having an aperture formed therethrough; c. a housing mounted on the movable structure and having bore formed therein, said housing positioned so that the aperture of the tongue of said pivot means is axially alignable with the bore thereof, said housing having a slot formed therein transverse to its bore and opening thereinto; d. a plunger axially insertable through the apreture of the tongue of said pivot means and into the bore of said housing, said plunger having a groove therein which aligns with the slot of said housing when said plunger is inserted therein; and e. locking latch means mounted on the movable structure and retractably movable through the slot of said housing into the groove of said plunger for releasably retaining said plunger within the bore of said housing.
Claim 3
Dependent Claim
21 words
A locking mechanism as claimed in claim 1 wherein said pivot means includes a hasp having the tongue hingedly mounted thereon.
Claim 4
Dependent Claim
36 words
A locking mechanism as claimed in claim 1 wherein said plunger includes a cylindrical shank having the groove formed in an annular configuration adjacent to one end thereof and having a flange on the opposite end.
Claim 5
Dependent Claim
34 words
A locking mechanism as claimed in claim 1 further including biasing means within the bore of said housing for engaging said plunger and yieldingly urging said plunger out of the bore of said housing.
Claim 6
Dependent Claim
104 words
A locking mechanism as claimed in claim 1 wherein said locking latch means comprises: a. a latch mounted on said housing for pivotable movement in a plane perpendicular to the longitudinal axis of the bore of said housing, said latch positioned so that its pivot plane is aligned with the slot formed in said housing; b. biasing means attached to the movable structure and to said latch for yieldingly urging the latch into the slot of said housing; and c. key-actuated means mounted on the movable structure adjacent to said housing for retracting said latch from the slot of said housing upon actuation thereof.
Claim 7
Dependent Claim
42 words
A locking mechanism as claimed in claim 5 wherein said latch has a notch formed on one end thereof for engagement by said key-actuated means, said latch having a tab formed along its length for entry into the slot of said housing.
Claim 8
Dependent Claim
53 words
A locking mechanism as claimed in claim 5 wherein said key-actuated means comprises: a. a lock having a portion thereof rotatable through an arc of substantially 90*; b. a lever attached to the rotatable portion of said lock and movable therewith; and c. a pin transversely mounted on one end of said lever.
Claim 9
Dependent Claim
108 words
A locking mechanism as claimed in claim 1 wherein said locking latch means comprises: a. a lock having a portion thereof rotatable through an arc of substantially 90*; b. a lever attached to the rotatable portion of said lock and movable therewith in a plane perpendicular to the longitudinal axis of the bore of said housing, said lever positioned so that its plane of rotation is in alignment with the slot of said housing, said lever extending from said lock so that its extending end will normally protrude into the bore of said housing and will be retracted therefrom when moved by said lock through its rotational plane.
