Abstract
A battery operated parking barrier which is directly driven by a motor between a blocking position and an open position, and a drive shaft which may be locked to resist external forces in the blocking position and in the open position.
Claims19
A barrier, comprising:
- a rotatable blocking arch, stable in a first, blocking position, and in a second, open position;
- a rotatable shaft, functionally connected to said blocking arch, rotating said arch between said first and second positions;
- an electric motor, functionally associated with said rotatable shaft, providing driving power to said shaft for rotation thereof;
- a power source providing power to said electric motor;
- a brake portion, slidably mounted on said shaft and actuated by said electric motor, said brake portion locking said shaft to external forces when said shaft is in a position corresponding to one of said blocking position and said open position of said arch;
- and
- a cam disposed on said shaft and rotatable therewith and engaging said motor, said cam transferring rotational force from said motor to said shaft.

- a power source providing power to said electric motor;
- a brake portion, slidably mounted on said shaft and actuated by said electric motor, said brake portion locking said shaft to external forces when said shaft is in a position corresponding to one of said blocking position and said open position of said arch;
- and
- a defense assembly including a spring and at least one link connecting said rotatable shaft to said rotatable arch, said link being free to move within an arc perpendicular to said shaft and being under pull tension from said spring,
- wherein movement of said link allows said arch to rotate relative to said shaft when rotational force exceeding a retaining force generated by said spring is applied to said arch from an external force.
