Garage parking position indicator

For use in indicating proper positioning of a vehicle travelling along an entry path into a garage for parking between a vehicle access door of the garage and a rear wall of the garage, apparatus comprising:

• means for receiving wave energy mountable inwardly of the access door on one side of the entry path at a point displaced from the rear wall by a distance greater than the length of the vehicle and at a height suitable for cross-secting the travelling vehicle from a leading to a trailing edge thereof;
• means mountable inwardly of the access door on an opposite side of the entry path from said receiving means for constantly transmitting and directing wave energy toward said receiving means along a path substantially transverse to the vehicle entry path whereby the presence of any portion of the vehicle on said transverse path interrupts reception of said wave energy by said receiving means;
• and
• first and second electric lights mountable in a rear portion of the garage and switching means electrically connectable between said lights and said receiving means for activating said first light in response to interruption of reception of said wave energy and for deactivating said first light and activating said second light in response to restoration of reception of said wave energy.

For use in indicating proper positioning of a vehicle travelling along an entry path into a garage for parking between a vehicle access door of the garage and a rear wall of the garage, apparatus comprising:

• means for receiving infrared wave energy mountable inwardly of the access door on one side of the entry path at a point displaced from the rear wall by a distance greater than the length of the vehicle and at a height suitable for cross-secting the travelling vehicle from a leading to a trailing edge thereof;
• means mountable inwardly of the access door on an opposite side of the entry path from said receiving means for constantly transmitting and directing coded infrared wave energy toward said receiving means along a path substantially transverse to the vehicle entry path whereby the presence of any portion of the vehicle on said transverse path interrupts reception of said coded wave energy by said receiving means;
• and
• a green and a red electric light mountable in a rear portion of the garage at approximately eye level of a driver of the vehicle;
• switching means electrically connectable between said lights and said receiving means for activating said green light in response to interruption of reception of said wave energy and for deactivating said green light and activating said red light in response to restoration of reception of said wave energy, and
• means for electrically disconnecting said red light a predetermined time after electrical connection thereof.
