Abstract

A bollard security system for opening and shutting an entrance or exit to a passageway includes a plurality of bollards activated by a drive system including a counterweight. The system includes vehicle and or personnel recognition and authorization system for lowering the bollards. The system can be operated manually when the drive system is non-operational.

Claims

1. A security system for selectively shutting and opening the vehicle entrance or exit or passage ways comprising:

base structure housing a support structure-and a main frame, wherein the main frame comprises a interconnected by steel channels, and wherein the main frame comprises a drive system for moving the bollard up and down;

a guide system for guiding movement of the bollards, wherein the guide system comprises a male and female part;

a counterweight coupled to the plurality of bollards to balance the bollards when moving up and down, with the help of the guide system; and

at least one sensor for identification of a vehicle or a person to initiate movement of the bollards in up or down direction.

2. The security system of claim 1, further comprising a top plate to withstand weight of the vehicle.

3. The security system of claim 1, wherein the base structure is constructed to support the support structure, the main frame, the plurality of bollards, and the counterweight.

4. The security system of claim 1, characterized in that the support structure is assembled to the base structure in such a way that it can take the complete upward and downward movement of the bollard along with complete load of the vehicle passing on it.

5. The security system of claim 1, wherein the main frame takes effective weight of the guide, and the counterweight.

6. The security system of claim 1, wherein the male part of the guide system is made of tool steel with phosphorous and the female part is made of steel with phosphorous bronze and is fitted to the male part to reduce the wear and tear.

7. The security system of claim 1, characterized in that the counterweight bears the equivalent load of the moving the bollard and that will minimize the load on the drive.

8. The security system of claim 1, wherein at least one sensor identifies and recognizes the vehicle or person by reading a card reader or a biometric system or any type of signal generation mechanism from a database storing information.

9. The security system of claim 1, wherein the security system can be operated manually.

10. The security system of claim 1, wherein the number of bollards comprises at least one bollard depending on size of the passage way or as per load of the vehicle.

11. The security system of claim 10, wherein height of the bollard is from 1500 mm to 2700 mm.

12. The security system of claim 11 wherein each of the bollards is a seamless tube having a height of 270 mm, a diameter of 150 mm and a thickness of 13 mm.

13. The security system of claim 1, wherein the drive system for moving the bollards up and down is characterized in that having a gear box with a motor for movement along with a drive shaft and at least one pulley—

which upon receiving instruction/information moves the bollards up or down.

14. The security system of claim 13 wherein the drive system comprises a pair of pulleys disposed on the drive shaft in spaced relation to each other.

15. The security system of claim 1 wherein the bollards have bottom ends and are interconnected at the bottom ends.

16. The security system of claim 12 wherein each of the bollards is a seamless tube.
