Patent ID: 7367161

Claim:
A gate opener comprising: a base plate secured to the ground; a gate; a bearing assembly that is secured to the base plate and supports the gate; a motor operatively connected to the bearing assembly, the motor having an output shaft; a male coupling operatively connected to the output shaft of the motor; a female coupling mated with the male coupling, the female coupling connected to the gate; and such that activation of the motor causes the output shaft to rotate in a first direction causing the male coupling to rotate causing the female coupling to rotate, in turn causing the gate to rotate, the rotation of the gate female coupling continuing until a limit is reached causing the motor to cease activation and upon subsequent activation of the motor the output shaft of the motor rotates in a second direction that is opposite to the first direction causing the gate to counterrotate and such that the bearing assembly, the output shaft of the motor, the male coupling and the female coupling are all aligned on a common longitudinal axis.
