Abstract
Abstract A device is provided for releasably securing a parked vehicle to an adjacent structure. The device includes a carriage first section affixed to the adjacent structure and a vertically adjustable carriage second section mounted on the first section and biased to assume a predetermined elevated position. The second section moves downwardly from the elevated position upon a predetermined external force being exerted thereon. A first element is mounted on the carriage second section for relative movement between an operative vehicle-locking mode and an inoperative vehicle-release mode. A second element is adjustably mounted on and substantially concealed by the carriage second section and coacts therewith and the first element to retain the latter in an operative mode. A manually actuated third element is carried on the carriage second section and is movable independently thereof to effect movement of the first element from the inoperative mode to the operative mode. The third element normally assumes a substantially concealed position within the carriage second section. A manually actuated fourth element is adjustably mounted on the carriage second section and is engageable with the second element to effect movement of the latter to a non-retaining position with respect to the first element, when the fourth element is manually activated in one relative direction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
234 words
A releasable locking device for securing a parked vehicle to an adjacent structure, said device comprising a carriage having a first section adapted to be affixed to the adjacent structure, and a second section mounted on said first section and biased to assume a predetermined elevated position, said second section being movable downwardly from said elevated position upon an external force of a predetermined magnitude being exerted on said second section; a first means mounted on said carriage second section for relative rectilinear movement with respect thereto between an operative vehicle-locking mode and an inoperative vehicle-release mode; releasable second means mounted on and substantially concealed by the carriage second section and coacting therewith and said first means for retaining the latter in said operative mode; manually actuated third means carried on said carriage second section and movable independently thereof between extended and retracted positions, when moving from a retracted position to an extended position said third means effecting relative movement of said first means from said inoperative mode to said operative mode, said third means normally assuming a retracted position and being substantially concealed within said carriage second section; and manually actuated fourth means adjustably mounted on said carriage second section and engageable with said second means to effect movement of the latter to a non-retaining position with respect to said first means, when said fourth means is manually actuated in one relative direction.
Claim 2
Dependent Claim
234 words
A releasable locking device for securing a parked vehicle to an adjacent structure, said device comprising a carriage having a first section adapted to be affixed to the adjacent structure, and a second section mounted on said first section and biased to assume a predetermined elevated position, said second section being movable downwardly from said elevated position upon an external force of a predetermined magnitude being exerted on said second section; a first means mounted on said carriage second section for relative rectilinear movement with respect thereto between an operative vehicle-locking mode and an inoperative vehicle-release mode; releasable second means mounted on and substantially concealed by the carriage second section and coacting therewith and said first means for retaining the latter in said operative mode; manually actuated third means carried on said carriage second section and movable independently thereof between extended and retracted positions, when moving from a retracted position to an extended position said third means effecting relative movement of said first means from said inoperative mode to said operative mode, said third means normally assuming a retracted position and being substantially concealed within said carriage second section; and manually actuated fourth means adjustably mounted on said carriage second section and engageable with said second means to effect movement of the latter to a non-retaining position with respect to said first means, when said fourth means is manually actuated in one relative direction.
Claim 3
Dependent Claim
26 words
The releasable locking device of claim 1 wherein the second means is spring biased to effect automatic retaining of the first means in the operative mode.
Claim 4
Dependent Claim
66 words
The releasable locking device of claim 2 wherein the second means includes a first lock component fixedly mounted on and substantially concealed by the carriage second section and a spring biased second complemental lock component carried on said first means and being substantially concealed by said carriage second section, said lock components normally being in interlocking relation when said first means is in said operative mode.
Claim 5
Dependent Claim
35 words
The releasable locking device of claim 1 wherein an external upward manual pull of predetermined magnitude exerted upon said third means effects movement of said first means from said inoperative mode to said operative mode.
Claim 6
Dependent Claim
31 words
The releasable locking device of claim 1 wherein an external upward manual pull of predetermined magnitude exerted upon said fourth means effects movement of said second means to said non-retaining position.
Claim 7
Dependent Claim
38 words
The releasable locking device of claim 4 or 5 wherein the third and fourth means are each provided with an exposed attachment element for selective engagement by a manually manipulated implement to impart an upward pulling force thereto.
Claim 8
Dependent Claim
62 words
The releasable locking device of claim 6 wherein the third means normally assumes a retracted position relative to the carriage second section and assumes an extended position when effecting movement of said first means from an inoperative mode to an operative mode; the attachment element of said third means being exposed when the latter is in either the retracted or extended position.
Claim 9
Dependent Claim
27 words
The releasable locking device of claim 7 wherein the attachment element is adapted to be selectively engaged and disengaged by one end of an elongated rodlike implement.
Claim 10
Dependent Claim
84 words
The releasable locking device of claim 7 wherein the third means includes a pair of elongated depending members arranged in spaced substantially parallel relation and having upper end portions thereof interconnected and provided with an attachment element, said third means being disposed in a sliding straddling relation with a portion of said first means, said elongated members having lower end portions in force-transmitting relation with said first means upon said third means assuming a predetermined extended position with respect to said carriage second section.
