Bollard and cable vehicle barrier
First Claim
1. A below-grade collapsible bollard and cable vehicle barrier system disposed in a vehicle pathway comprising:
- a. a vault having a top, a bottom, two ends, an approach side and a shoulder side, said vault being located near the center of said vehicle pathway;
b. a rod rotatably mounted inside said vault, said rod extending perpendicular to the direction of traffic movement;
c. a bollard having a first end and a second end, said bollard being coupled to said rod substantially near said first end, whereby rotation of said rod rotates said bollard to extend the second end thereof above said vault in a vertical direction, hereafter raised position;
d. an actuator having a first end secured within said vault and a second end coupled to said rod through an arm, said actuator being disposed for rotating said rod; and
, e. a cable having each end thereof affixed to deadweight anchors on either side of said vehicle pathway, and said cable being disposed perpendicular to said vehicle pathway, said cable also being affixed near the second end of said bollard, whereby when said bollard is in said raised position said cable is stretched across said vehicle pathway and when said bollard is in a lowered position said cable is relaxed on said vehicle pathway.

Abstract
A below-grade collapsible bollard and cable vehicle barrier system disposed in a vehicle pathway. The system comprises one or more bollard devices that include a vault located in the vehicle pathway, a rod rotatably mounted inside the vault, a bollard having a first end coupled to the rod, whereby rotation of the rod rotates the bollard to extend the second end thereof above the vehicle pathway. An actuator is secured within the vault for rotating the rod and thus raising the bollard. A cable is disposed perpendicular to the vehicle pathway with each end thereof affixed to anchors on either side of the pathway. The middle of the cable is affixed to the second end of the bollard. When the bollard is raised the cable is stretched across the pathway forming a barrier to traffic.

7. An automatic self-contained below-grade collapsible bollard and cable traffic barrier system disposed in a vehicle pathway comprising:
-
a. a vault having a top, a bottom, two ends, an approach side and a shoulder side;
b. a rod rotatably mounted to support members inside said vault, said rod extending across said vault from end to end and perpendicular to traffic flow;
c. a bollard having a first end and a second end, said bollard being coupled to said rod substantially near said first end, whereby rotation of said rod rotates said bollard so as to extend the second end thereof above said vault in a vertical direction, hereafter raised position;
d. a sleeve for removably receiving said bollard near said first end thereof, said sleeve being secured to said rod by means of brackets welded to both said sleeve and said rod, said bollard being removably secured to said sleeve by means of a removable pin;
e. an actuator having a first end anchored within said vault and a second end coupled to said rod by means of an arm, said actuator being disposed for rotating said rod; and
,f. a cable having each end anchored on either side of said vehicle pathway, said cable being disposed perpendicular to said vehicle pathway, said cable also being affixed near the second end of said bollard, whereby when said bollard is in said raised position said cable is s stretched across said vehicle pathway and when said bollard is in a lowered position said cable is relaxed on said vehicle pathway. - View Dependent Claims (8, 9, 10, 11)

12. An automatic self-contained below-grade bollard and cable traffic control apparatus, said apparatus comprising:
-
a. a plurality of bollard devices spaced across a vehicle pathway, each device comprising;
i) a vault adapted for being placed transverse said vehicle pathway and in the pavement thereof, said vault having a top, a bottom, two ends, an approach side and a shoulder side;
ii) a rod rotatably mounted to support members inside said vault, said rod extending across said vault perpendicular to the direction of traffic movement;
iii) a bollard having a first end and a second end, said bollard being coupled to said rod substantially near said first end thereof, whereby rotation of said rod rotates said bollard so as to extend the second end thereof above said vault in a vertical direction, hereafter raised position;
iv) an actuator having a first end anchored within said vault and a second end coupled to said rod by means of an arm, said actuator being disposed for rotating said rod; and
,b. a cable stretched across said vehicle pathway and being coupled near the second of each of said bollards, whereby when said bollards are in said raised position said cable is stretched across said vehicle pathway and when said bollards are in a lowered position said cable is relaxed on said vehicle pathway. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
