Abstract
Abstract A motor vehicle parking space barrier for preventing unauthorized use of a parking space. A lateral blocking arm is mounted to an upright post. The post is mounted for reciprocable longitudinal movement in a fixed base. When locked, a novel mechanism prevents longitudinal movement of the blocking arm, thereby preventing usage of the parking space. When unlocked, the barrier can be pushed by the vehicle to a non-blocking position. A resilient means returns the barrier to its initial position when the vehicle leaves the parking space. Means are provided for allowing the driver to unlock the locking mechanism without getting out of the vehicle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
86 words
A parking space barrier comprising a hollow base having a longitudinal slot therein, a vertical post movably mounted in said base for reciprocable longitudinal movement with respect to said base to blocking and non-blocking positions and projecting upwardly through said slot, resilient means in said base engaging said post for resiliently urging longitudinal movement of said post in one direction, a blocking arm mounted for movement in unison with said post, and locking means for fixedly preventing longitudinal movement of said post while in blocking position.
Claim 2
Dependent Claim
86 words
A parking space barrier comprising a hollow base having a longitudinal slot therein, a vertical post movably mounted in said base for reciprocable longitudinal movement with respect to said base to blocking and non-blocking positions and projecting upwardly through said slot, resilient means in said base engaging said post for resiliently urging longitudinal movement of said post in one direction, a blocking arm mounted for movement in unison with said post, and locking means for fixedly preventing longitudinal movement of said post while in blocking position.
Claim 3
Dependent Claim
39 words
The parking barrier of claim 1, wherein said blocking arm is transverse to said post, and also including a longitudinally extending arm connected to said blocking arm and said post whereby said blocking arm is displaced from said post.
Claim 4
Dependent Claim
17 words
The parking barrier of claim 2, also including means for fixedly securing said base to the ground.
Claim 5
Dependent Claim
73 words
The parking barrier of claim 2, wherein said vertical post is hollow and has upper and lower vertical slots therein, and said locking means comprises a vertical rod movably mounted within said vertical post, a lateral pin fixedly connected to said rod and projecting through said upper vertical slot, a cam means rotatably mounted to said post for movement of said pin, and a lock mounted to said cam means and said pin.
Claim 6
Dependent Claim
73 words
The parking barrier of claim 4, wherein said locking means also includes a spring exerting upward force on said rod, a stop mounted inside said base, a lower lateral pin fixedly connected to said rod and projecting through said lower vertical slot whereby said lower pin engages said stop in the locked position and is spaced from said stop when said cam means is rotated to the unlocked position to overcome said spring.
