Abstract
Abstract A post is adapted to be raised to an active position in front of a vehicle being serviced from a pit beneath the vehicle, the post serving as a barrier to guard against injury and property damage in the event the vehicle suddenly lurches forwardly. After the vehicle has been serviced, the post may be lowered to a stored position in the pit to enable the vehicle to be driven forwardly from the service area.

Claim 1
Independent Claim
175 words
The combination of, a vehicle lubrication service pit having front and rear end portions, and a vehicle barrier selectively operable to form a safety stop adjacent the front end portion of the pit for a vehicle disposed above the pit for servicing, said barrier comprising a framework secured to the front end portion of said pit near the upper side thereof, a sleeve secured to and depending from said framework and extending downwardly into the front end portion of the pit, a barrier post supported slidably within said sleeve for up and down movement between a raised active position and a lower stored position, said post presenting an obstacle to forward movement of the vehicle when in said active position and being located below and clear of the undercarriage of the vehicle when in said stored position, means for urging said post upwardly toward said active position, and means independent of said urging means for holding said post in said active position and selectively releasable to permit lowering of said post to said stored position.

Claim 7
Dependent Claim
57 words
