Abstract
Abstract A locking bar system having a lock assembly insertable within the bores of aligned lug members. One of the lug members has a passage of predetermined contour formed within an inner wall. The lock assembly includes a lock plug insertable within a locking tube. A locking pin is rigidly secured to and is immovable with respect to the lock plug and passes through a channel formed in a sidewall of the locking tube. The locking pin extends into the passage formed in the lug member with the position of the locking pin within the passage determining whether the system is locked or unlocked. The lock plug is prevented by means of the locking pin from axial movement with respect to the locking tube.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
A bar lock system comprising: a. a pair of strike plates having alignable lug members, each of said lug members having a bore opening defining an inner wall, at least one of said lug members having a continuously formed passage of predetermined contour formed within said inner wall; b. lock assembly means having (1) a locking pin of constant extension therefrom and movably actuated within said passage, (2) a locking tube insertable within said bore openings of said lug members, and (3) lock means positionally located within said locking tube; said locking pin being rigidly secured to and immovable with respect to said lock means said lock means and said locking pin being rotatable with respect to said locking tube through a predetermined angular displacement, and said locking tube being fixedly secured with respect to rotational movement within said bore openings of said lug members.
Claim 2
Dependent Claim
145 words
A bar lock system comprising: a. a pair of strike plates having alignable lug members, each of said lug members having a bore opening defining an inner wall, at least one of said lug members having a continuously formed passage of predetermined contour formed within said inner wall; b. lock assembly means having (1) a locking pin of constant extension therefrom and movably actuated within said passage, (2) a locking tube insertable within said bore openings of said lug members, and (3) lock means positionally located within said locking tube; said locking pin being rigidly secured to and immovable with respect to said lock means said lock means and said locking pin being rotatable with respect to said locking tube through a predetermined angular displacement, and said locking tube being fixedly secured with respect to rotational movement within said bore openings of said lug members.
Claim 3
Dependent Claim
125 words
A bar lock system comprising at least one strike plate having a bore opening, a locking tube insertable with said bore opening and having at least one opening passing through a sidewall thereof, lock means disposed within and being rotatable with respect to said locking tube, said bore opening having an inner wall, a passage of predetermined contour formed in said inner wall, and a locking pin rigidly secured to and immovable with respect to said lock means, said locking pin extending through said sidewall opening and into said passage so that the lock means is partially rotatable for moving said locking pin within said passage but said lock means is prevented by said locking pin from axial movement with respect to the locking tube.
Claim 4
Dependent Claim
125 words
A bar lock system comprising at least one strike plate having a bore opening, a locking tube insertable with said bore opening and having at least one opening passing through a sidewall thereof, lock means disposed within and being rotatable with respect to said locking tube, said bore opening having an inner wall, a passage of predetermined contour formed in said inner wall, and a locking pin rigidly secured to and immovable with respect to said lock means, said locking pin extending through said sidewall opening and into said passage so that the lock means is partially rotatable for moving said locking pin within said passage but said lock means is prevented by said locking pin from axial movement with respect to the locking tube.
Claim 5
Dependent Claim
39 words
The bar lock system of claim 2 in which said locking tube is fixedly secured with respect to said bore opening to prevent rotational movement but allow axial movement of said locking tube with respect to said bore opening.
Claim 6
Dependent Claim
37 words
The bar lock system as recited in claim 3, where said predetermined contour of said passage includes a pair of passage extensions, each joined to a longitudinally directed groove passing substantially normal to each of said extensions.
Claim 7
Dependent Claim
30 words
The bar lock system as recited in claim 4 where said locking pin is rotatably movable within each of said passage extensions responsive to a rotation of said lock means.
Claim 8
Dependent Claim
30 words
The bar lock system of claim 2 in which there are provided a pair of strike plates having alignable lug members, each of said lug members having a bore opening.
Claim 9
Dependent Claim
52 words
The bar lock system as recited in claim 6 including: a. first mating means formed on at least one of said strike plates; and, b. second mating means formed on a sidewall of at least one of said lug members, said first and second mating means being received one in the other.
Claim 10
Dependent Claim
36 words
The bar lock system as recited in claim 7 where said first mating means includes a tooth element insertable within a corresponding second mating means for restraining motion between said strike plates in a predetermined direction.
Claim 11
Dependent Claim
38 words
The bar lock system as recited in claim 8 where said second mating means includes a channel formed within at least one of said lugs for insertion of at least one tooth element of said first mating means.
Claim 12
Dependent Claim
36 words
The bar lock system as recited in claim 7 where said second mating means includes a tooth element insertable within a corresponding first mating means for restraining motion between said strike plates in a predetermined direction.
