Abstract

A security bollard system with a housing and at least one bollard assembly. The housing has an interior and a top surface with an opening through the top surface into the interior. The bollard assembly is positioned within the housing and includes a bollard. The bollard is rotatably coupled to the interior of the housing and is rotatable between a lowered position and a raised position. When in the lowered position, the bollard is positioned in the interior of the housing and when in the raised position, the bollard extends up through the opening in the top surface of the housing. Each bollard is configured to be moved between the lowered positioned and the raised position manually. Additionally, each bollard has a pivot point about which the bollard rotates that is positioned to balance the bollard about the pivot point and limit torque required to rotate the bollard.

Claims (41)

1 . A security bollard system comprising:

a housing having an interior and a top surface with at least one opening through the top surface into the interior and at least one cover panel configured to cover the at least one opening; and

at least two bollard assemblies positioned within the housing, each bollard assembly of the at least two bollard assemblies comprising:

a bollard rotatably coupled to the interior of the housing through a bearing, the bollard manually rotatable between a lowered position and a raised position, wherein when in the lowered position, the bollard is positioned in the interior of the housing and oriented parallel with the top surface of the housing and when in the raised position, the bollard extends up through the at least one opening perpendicular to the top surface of the housing;

an upper stop positioned within the interior of the housing to contact the bollard when the bollard is in the raised position;

a locking tab extending away from the bollard and having a locking aperture, the locking aperture configured to align with the upper stop when the bollard is in the raised position; and

a locking pin configured to engage with the upper stop and the locking aperture to couple the locking tab to the upper stop and lock the bollard in the raised position;

wherein the bollard has a pivot point about which the bollard rotates that is positioned to balance the bollard about the pivot point and limit a torque required to rotate the bollard about the pivot point;

wherein each bollard of the at least two bollard assemblies rotates in a direction opposite from each adjacent bollard of the at least two bollard assemblies;

wherein each bollard is configured to rotate about an axis extending in a first direction and impede vehicle motion in the first direction; and

wherein each bollard is configured to be moved between the lowered position and the raised position manually.

2 . The security bollard system of claim 1 , further comprising at least one drain hole through a bottom of the housing, the at least one drain hole configured to drain fluid out of the housing.

3 . The security bollard system of claim 1 , each bollard assembly further comprising a protrusion coupled to and extending away from the at least one cover panel and configured to hold the bollard in the lowered position when the at least one cover panel is positioned to cover the at least one opening.

4 . A security bollard system comprising:

a housing having an interior and a top surface with at least one opening through the top surface into the interior; and

at least one bollard assembly positioned within the housing, each of the at least one bollard assembly comprising:

a bollard rotatably coupled to the interior of the housing, the bollard rotatable between a lowered position and a raised position, wherein when in the lowered position, the bollard is positioned in the interior of the housing and when in the raised position, the bollard extends up through the at least one opening;

an upper stop positioned within the interior of the housing to contact the bollard when the bollard is in the raised position;

a locking tab extending away from the bollard, the locking tab configured to align with the upper stop when the bollard is in the raised position; and

a locking pin configured to engage with the upper stop and the locking tab to couple the locking tab to the upper stop and lock the bollard in the raised position;

wherein the bollard of each of the at least one bollard assembly has a pivot point about which the bollard rotates that is positioned to balance the bollard about the pivot point; and

wherein the bollard of each of the at least one bollard assembly is configured to rotate about an axis extending in a first direction and impede vehicle motion in the first direction.

5 . The security bollard system of claim 4 , wherein the pivot point is positioned to limit a torque required to rotate the bollard about the pivot point.

6 . The security bollard system of claim 4 , wherein the bollard is rotatably coupled to the interior of the housing through a bearing.

7 . The security bollard system of claim 4 , wherein when the bollard is in the lowered position, the bollard is oriented parallel with the top surface of the housing and when the bollard is in the raised position, the bollard is perpendicular to the top surface of the housing.

8 . The security bollard system of claim 4 , the locking tab having a locking aperture, wherein the locking pin is configured to engage with the upper stop and the locking aperture to lock the bollard in the raised position.

9 . The security bollard system of claim 4 , wherein the bollard is configured to be moved between the lowered position and the raised position manually.

10 . The security bollard system of claim 4 , wherein the at least one bollard assembly comprises at least a first bollard assembly and at least an adjacent bollard assembly, and wherein the bollard of the first bollard assembly rotates in a direction opposite from the bollard of the adjacent bollard assembly.

11 . The security bollard system of claim 4 , further comprising at least one drain hole through a bottom of the housing, the at least one drain hole configured to drain fluid out of the housing.

12 . A security bollard system comprising:

at least one bollard assembly, each bollard assembly of the at least one bollard assembly comprising:

a bollard rotatable between a lowered position and a raised position, wherein when in the lowered position, the bollard is oriented to allow a vehicle to pass over the security bollard system and when in the raised position, the bollard is oriented to impede the vehicle from passing over the security bollard system; and

a locking assembly comprising a locking tab extending away from the bollard and a locking pin configured to engage with the locking tab and lock the bollard in the raised position:

wherein the bollard is configured to rotate about an axis extending in a first direction and impede vehicle motion in the first direction when the bollard is in the raised position.

13 . The security bollard system of claim 12 , further comprising a housing having an interior and a top surface with at least one opening through the top surface of the interior, wherein the at least one bollard assembly is positioned within the housing.

14 . The security bollard system of claim 13 , wherein when in the lowered position, the bollard is positioned in the interior of the housing and when in the raised position, the bollard extends up through the at least one opening.

15 . The security bollard system of claim 12 , the locking assembly comprising an upper stop positioned to contact the bollard when the bollard is in the raised position.

16 . The security bollard system of claim 15 , wherein the locking tab configured to align with the upper stop when the bollard is in the raised position, and a locking pin configured to engage with the upper stop and the locking tab to couple the locking tab to the upper stop and lock the bollard in the raised position.

17 . The security bollard system of claim 12 , wherein the bollard has a pivot point about which the bollard rotates that is positioned to balance the bollard about the pivot point.

18 . The security bollard system of claim 12 , wherein the bollard is configured to be moved between the lowered position and the raised position manually.

19 . The security bollard system of claim 12 , wherein the at least one bollard assembly comprises at least a first bollard assembly and at least an adjacent bollard assembly, and wherein the bollard of the first bollard assembly rotates in a direction opposite from the bollard of the adjacent bollard assembly.
