Parking space holder
A parking space is reserved by raising a chain about three feet above a parking space. The chain is attached to a post, and a weight is attached to the chain to lower the chain along the post and to drag the lowering chain along the parking space toward the post for full access. A motor with a speed reducer turns a shaft with a chain drive gear and an encoder. A signal receiver and control start the motor to raise or lower the chain when one of two buttons is pressed on a key fob by the authorized space user. The encoder is connected to the control to stop the chain when fully up or down. A stop trigger on the chain activates a stop switch when the chain is fully raised.
