Claims
- 1. Safety system for entering and exiting garage doors and entrances comprising:a warning sign adapted to be placed by an attachment means at a primary line of sight of a driver of a truck during lowering and raising movement of said door; a delay means provided to facilitate a movement of said sign in such manner that said sign will always appear first in the primary line of sight of said driver to eliminate a possibility of collision between said truck and said door; a moving means adapted to lower said sign into an operational position and provided to keep said sign in non-operational retracted position when said door is completely open to ensure clearance for moving truck.
- 2. Safety system according to claim 1, wherein said warning sign is activated by a warning sign activating means.
- 3. Safety system according to claim 2, wherein said warning sign moving means is a motor-driven assembly.
- 4. Safety system according to claim 3, wherein said door is activated by a detector adapted to transmit signal to a door control panel operating the movement of said door by means of a door motor.
- 5. Safety system according to claim 4, wherein warning sign activating means is a warning sign control panel, said warning sign control panel is adapted to monitor signals sent from said detector to said door control panel.
- 6. Safety system according to claim 5, wherein the signal transmitted from said door control panel to said door motor is intercepted by said warning sign control panel.
- 7. Safety system according to claim 6, wherein said door is lowered down by a detector adapted to send signal to said door control panel.
- 8. Safety system according to claim 7, wherein said signal is intercepted by said warning sign control panel activating the warning sign to be lowered down before said door is closed.
- 9. Safety system according to claim 3, wherein said sign is attached to said motor-driven assembly by a system of cables connected to a respective set of drums mounted on a shaft.
- 10. Safety system according to claim 3, wherein said sign is attached to said motor-driven assembly by a cable connected to a drum and a lazy-tongs system.
- 11. Safety system according to claim 3, wherein said sign is attached to said motor-driven assembly by a rigid plate pivotally connected to a shaft.
- 12. Safety system according to claim 3, wherein said sign is attached to said motor-driven assembly by cables connected to a drum rotatable by a tubular motor mounted within said drum.
- 13. Safety system according to claim 3, wherein said sign is fixed to a side of said entrance.
- 14. Safety system according to claim 3, wherein said warning sign is attached to said motor-driven assembly by a pivoting arm adapted to pivot said sign into a retracting position.
- 15. Safety system according to claim 3, wherein said warning sign motor-driven assembly is a motor driven drum adapted to wind and unwind the attachment means of said sign.
- 16. Safety system according to claim 2, wherein said sign is attached to a lower edge of said door by a pivoting arm adapted to be pivoted around a pivot mounted on said door, and wherein pivoting movement of said arm is restricted by a first stopper provided to maintain the angle of the arm when said door is between an open and a closed position and a second stopper mounted to an upper frame of the entrance to facilitate the pivoting upward movement of said arm when the door is opening.
- 17. Safety system according to claim 2, wherein said warning sign activating means is a locking element connected to a set of drums provided with cables facilitating manual operation of the door, and wherein said locking device is provided to prevent the door to be opened or closed in case the sign is not completely down.
- 18. Safety system according to claim 1, wherein said sign is fixed above said door.
- 19. Safety system according to claim 1, wherein said door is provided with an additional alarm means installed in the vicinity of said door to increase the reaction time for said driver before the door will start to close or is not completely open.
- 20. Safety system according to claim 6, wherein said delay means is activated by said door control means at a predetermined delay period set by the signal sent from said sign control panel.
- 21. Safety system according to claim 20, wherein said warning sign delay means is an electric delay system provided to allow an additional delay time right after said sign is down to increase the reaction time for the driver before the door will start to close.
- 22. Safety system according to claim 1, wherein said door is provided with a sensor adapted to give additional warning signal to the driver in case said truck is very close to the door.
- 23. Safety system according to claim 1, wherein said sign stays down when said door is completely closed.
- 24. Safety system according to claim 1, wherein said sign stays up when said door is completely closed.
- 25. Safety system according to claim 1, wherein the dimensions of said sign are larger than a width of said entrance to facilitate a better visibility of said sign when the truck is backing up towards the entrance.
