Abstract
Abstract A barrier post to prevent unauthorized use of a private parking space includes a firmly anchored base and a post which is shiftable from an upright barrier position to a lowered inactive position. A simplified locking and release mechanism permits separating the post from its shear pin holding means by a lifting and pivoting manipulation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
198 words
A parking space barrier comprising a base adapted to be anchored to a floor or to ground and having a pair of spaced upright elements, a cross pin secured to and extending between said elements near their upper ends, opposing shear pins removably mounted on said elements near their lower ends and below said cross pin and projecting interiorly of said elements, a barrier post engaged between said upright elements and having bottom end opening slots in opposite sides thereof engaging over the shear pins removably and having vertically elongated closed end sloTs in the same opposite sides thereof above the firstnamed slots and slidably and pivotally receiving said cross pin, a key lock on said post near the top thereof including a rotary crank arm within the post, and a link connected with said crank arm and moved thereby and extending through the post and having a lower end loop receiving said cross pin with sufficient play between the loop and cross pin to allow the loop to be lowered by turning of the crank arm to release the post for lifting relative to the cross pin sufficiently to separate said shear pins from said first-named slots.
Claim 2
Dependent Claim
198 words
A parking space barrier comprising a base adapted to be anchored to a floor or to ground and having a pair of spaced upright elements, a cross pin secured to and extending between said elements near their upper ends, opposing shear pins removably mounted on said elements near their lower ends and below said cross pin and projecting interiorly of said elements, a barrier post engaged between said upright elements and having bottom end opening slots in opposite sides thereof engaging over the shear pins removably and having vertically elongated closed end sloTs in the same opposite sides thereof above the firstnamed slots and slidably and pivotally receiving said cross pin, a key lock on said post near the top thereof including a rotary crank arm within the post, and a link connected with said crank arm and moved thereby and extending through the post and having a lower end loop receiving said cross pin with sufficient play between the loop and cross pin to allow the loop to be lowered by turning of the crank arm to release the post for lifting relative to the cross pin sufficiently to separate said shear pins from said first-named slots.
Claim 3
Dependent Claim
40 words
A parking space barrier as defined by claim 1, and wherein the shear pins have screw-threaded engagement with said upright elements to allow separation of shear pin shanks from said elements and replacement of the shear pins following failure thereof.
Claim 4
Dependent Claim
31 words
A parking space barrier as defined by claim 1, and said lower end loop of said link being elongated axially of the link and slidably and pivotally receiving said cross pin.
Claim 5
Dependent Claim
32 words
A parking space barrier as defined by claim 3, and said bottom end opening slots being downwardly flared and the upper portions of the slots slidably and pivotally engaging said shear pins.
Claim 6
Dependent Claim
53 words
A parking space barrier as defined by claim 1, and said base including a flat base plate adapted to rest on a floor, said upright elements comprising spaced parallel plate elements, said barrier post being rectangular in cross section and one opposing pair of sides of said post fitting between said plate elements.
