Abstract

A dispensing system and method utilizing a break-away antenna in a radio frequency customer identification system for service stations to reliably and accurately identify and charge customers for their purchases. The antenna is formed by a bracket adapted to be affixed to the object, a rod pivotally mounted to the bracket, and a spring normally urging the rod to a first position, the rod being pivotal to a second position in response to a force applied to the rod in a direction towards the second position.

Claims

1. A gasoline dispensing system comprising a dispenser for dispensing fuel to vehicles and comprising a housing, a nozzle extending from the housing for receiving gasoline from a storage tank and dispensing the gasoline into a vehicle tank, and a mounting bracket affixed to the housing;

and an antenna for receiving transmitted customer identification information from the vehicle, the antenna comprising a rod pivotally mounted to the mounting bracket, and a member normally urging the rod to a first position, the rod being pivotal to a second position in response to a force applied to the rod in a direction towards the second position.

2. The system of claim 1 wherein the member is a spring that engages the mounting bracket and the rod and returns the rod to its first position after release of the force.

3. The system of claim 1 further comprising a shaft mounted on the bracket, and wherein the rod comprises at least one flange having an opening for receiving the shaft to pivotally mount the rod to the mounting bracket.

4. The system of claim 3 wherein the mounting bracket is movable in a lateral direction along the axis of the shaft in response to a force being applied to the rod in the lateral direction, and wherein the mounting bracket comprises a member for imparting the pivotal movement to the rod in response to application of the latter force.

5. The system of claim 1 wherein the mounting bracket is fastened to the upper surface of the housing and wherein the rod projects outwardly from a wall of the housing in the first position.

6. The system of claim 5 wherein the first position is horizontal and wherein the second position is vertical.

7. An antenna for mounting to an object, the antenna comprising a mounting bracket adapted to be affixed to the object, a shaft mounted on the bracket, a rod comprising at least one flange having an opening for receiving the shaft to pivotally mount the rod to the bracket, and a member normally urging the rod to a first position, the rod being pivotal to a second position in response to a force applied to the rod in a direction towards the second position.

8. The antenna of claim 7 wherein the member is a spring that engages the mounting bracket and the rod and returns the rod to its first position after release of the force.

9. The antenna of claim 7 wherein the rod is movable in a lateral direction along the axis of the shaft in response to a force being applied to the rod in the lateral direction, and wherein the bracket comprises a member for imparting the pivotal movement to the rod in response to application of the latter force.

10. The antenna of claim 7 wherein the bracket is fastened to a surface of the object and wherein the rod projects outwardly from the object in the first position.

11. The antenna of claim 10 wherein the first position is horizontal and wherein the second position is vertical.

12. A method of dispensing gas comprising the step of providing a dispenser equipped with a nozzle for insertion into the fuel tank of a vehicle, providing a transponder on the vehicle for transmitting customer identification information to the dispenser for processing, and mounting an antenna on the dispenser in a first position for receiving the transmitted information, and permitting the antenna to pivot to a second position in response to a force applied to the antenna in a direction towards the second position.

13. The method of claim 12 wherein the antenna returns to the first position after release of the force.
