Abstract

An RV trailer motion lock-out system is provided for installation on an RV trailer having a brake light and having at least one protruding component with a corresponding protruding component activation unit for extending said protruding component. A detect circuit detects when voltage is applied to the brake light for illuminating the brake light. A lock-out circuit controls the protruding component activation unit to permit the extending of the protruding component upon user command, and once the brake light is illuminated, the lock-out circuit latches for preventing the extending of the protruding component, the illumination of the brake light being indicative of transit of the RV trailer.

Claims

1. An RV trailer motion lock-out system for installation on an RV trailer having a brake light and having at least one protruding component with a corresponding protruding component activation unit for extending said protruding component, comprising:

a detect circuit for detecting when voltage is applied to said brake light for illuminating the brake light; and

a lock-out circuit which controls said protruding component activation unit to permit said extending of said protruding component upon user command, and once the brake light is illuminated, the lock-out circuit latches for preventing the extending of said protruding component, said illumination of said brake light being indicative of transit of said RV trailer.

2. The system of claim 1 wherein said motion lock-out system comprises a motion lock-out switch located inside of said RV trailer.

3. The system of claim 2 wherein said motion lock-out switch comprises a momentary toggle switch with an associated activating button.

4. The system of claim 2 wherein said lock-out switch is located on an inside wall of said RV trailer.

5. The system of claim 2 wherein an indicator light is provided adjacent said lock-out switch which is illuminated when said RV trailer is parked and said protruding component activation unit can be activated for extending said protruding component.

6. A system of claim 1 wherein said protruding component activation unit comprises a power switch for feeding power to a power unit for extending said protruding component.

7. The system of claim 1 wherein said protruding component activation unit comprises a protruding component control circuit for activating a power unit for extending said at least one protruding component.

8. The system of claim 2 wherein said lock-out circuit comprises a filter for filtering out a debounce signal caused by said motion lock-out switch.

9. The system of claim 1 wherein said motion lock-out circuit comprises a function toggle flip-flop.

10. The system of claim 1 wherein said protruding component activation unit is either a protruding component power switch or a protruding component control circuit, and said lock-out circuit has a relay for switching a battery voltage to either a motion lock-out line connecting to said power switch or to said protruding component control circuit via a pseudo-ignition line.

11. The system of claim 1 wherein said motion lock-out system comprises a control panel with an associated enclosure for housing electronic components, said control panel with said enclosure for mounting to an inside wall of said RV trailer.

12. The system of claim 1 wherein said at least one protruding component comprises at least one of a slide-out room, an awning, a landing gear, a leveling system, or steps.

13. The system of claim 1 wherein said lock-out circuit comprises a user operated toggle switch for permitting a user to toggle between a first mode in which said protruding component cannot be extended and a second mode wherein said protruding component can be activated to be extended.

14. An RV vehicle motion lock-out system for installation on an RV trailer having a brake light and having at least one protruding component with a corresponding protruding component activation unit for extending said protruding component, comprising:

a detect circuit for detecting when voltage is applied to said brake light illuminating the brake light;

a lock-out circuit which controls said protruding component activation unit to permit said extending of said protruding component upon user command, and when the brake light is illuminated, the lock-out circuit latches and changes to a state in which extension of said protruding component is disabled, said illumination of said brake light being indicative of transit of said RV trailer; and

said lock-out circuit having a toggle switch for toggling between said state in which extension of said protruding component is disabled and another state wherein extension of said protruding component is enabled.

15. The system of claim 14 wherein the lock-out circuit includes an indicator light which is illuminated when the trailer is parked.
