Claim 6

A vehicular barrier system for restricting movement in a vehicle way, placed below the surface of such vehicle way including a bollard selectively protuberant above the surface of such vehicle way comprising: a casing implanted below such vehicle way; an electromechanical drive mechanism including a reversible motor retained as a unit within said casing and coupled to the bollard for erecting or retracting the bollard to or from a protuberant position obstructing movement in such vehicle way; a bezel surrounding the bollard and releasably secured to said casing for restricting access to the electromechanical drive mechanism; a locking assembly means integral with the bollard permitting limited rotation for access to the bollard for replacement, adjustment or repair; an electronic control means associated with the motor of the electromechanical drive mechanism for activating the motor to operate the electromechanical drive mechanism for erecting or retracting the bollard.

Claim 7

The vehicular barrier system of claim 3 wherein the electromechanical drive mechanism further includes: a drive shaft having a threaded region, a traveler nut threaded upon the threaded region of the drive shaft, said drive shaft coupled to said motor; a main bearing housing for the drive shaft; a tubular plastic housing seated over the main bearing housing; a plastic cover for said tubular plastic housing; a roller guide means within said plastic cover; a cable means secured to the traveler nut extending through the plastic cover over the roller guide means and secured to the lower end of the bollard; and a stabilizer means to prevent rotation of the traveler nut with the drive shaft, thereby causing the traveler nut to move up or down the threaded region of the drive shaft carrying the cable means and bollard therewith when the drive shaft rotates.

Claim 8

The vehicular barrier system of claim 4 wherein the traveler nut is fluted and of non-magnetic material and the stabilizer means includes a tubular plastic guide extending from the main bearing housing to the plastic cover with the fluted area of the traveler nut engaging the plastic guide and includes; a proximity switch mechanism including an adjustable magnetic carrier with a magnet at the upper end and at the lower end seated within the plastic guide; said traveler nut of non-magnetic material having a magnet carried thereon; and said electronic control means including means for activating the motor and deactivating the motor responsive to the magnet carried by the traveler nut approaching the proximity of the upper magnet or the lower magnet.

Claim 9

The vehicular barrier system of claim 3 wherein the electromechanical drive mechanism further includes a drive shaft having a threaded region, a traveler nut threaded upon the threaded region of the drive shaft, said drive shaft coupled to said motor and includes: a riser tube, surrounding the drive shaft, secured at the lower end to the traveler nut and at the upper end to the bollard, and a stabilizer means to prevent rotation of the traveler nut with the drive shaft, thereby causing the traveler nut to move up or down the threaded region of the drive shaft carrying the riser tube and bollard therewith when the drive shaft rotates.

Claim 10

The vehicular barrier of claim 6 which includes a main bearing housing for the drive shaft, a tubular plastic housing surrounding the traveler nut and seated over and sealed to the main bearing housing, and a plastic cover for said tubular plastic housing surrounding and sealed to the riser tube.
