Description
ACCESSORY FOR A LOCKING ASSEMBLY
FIELD OF THE INVENTION
The present invention relates to locking devices and more particularly, relates to an accessory for a locking assembly.
BACKGROUND OF THE INVENTION
Theft, as it relates to vehicles, is an ongoing problem. Such theft can range from stealing the contents of a vehicle to the theft of the vehicle itself. One particular problem relates to trailers.
Various types of trailers are widely used including RV type trailers as well as commercial trailers utilized to transport goods from one location to a second location.
Often the theft of the trailer will occur when the trailer is unattended. In order to prevent such theft, some trailers utilize devices such as padlocks and chains for attaching a trailer to an adjacent fixed object such as a post or the like. However, such chains and padlocks can be defeated by use of bolt cutters, torches, and the like. Even when the trailer is attached to its own vehicle, theft can occur when the trailer is unattended. Again, various tools or implements can be utilized to detach the trailer and steal the same.
In order to overcome the above, it has been proposed in the art to utilize locking assemblies such as the one shown in United States Patent 7,040,646. The locking assembly shown in this patent can be utilized for securing the trailer hitch such that the trailer cannot be attached to a different vehicle. The assembly makes it extremely difficult for theft of the trailer to occur. However, it has been found that theft will still occur through the negligence of the person using the trailer. Whether on purpose or by accident, the use of the locking assembly is sometimes neglected and thus theft can occur.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a device for use with a locking assembly and which device will function to remind the user to secure the locking assembly once the trailer has been detached from the cab or other towing vehicle.
According to one aspect of the present invention, there is provided a device for use with an anti-theft locking assembly, the device comprising an enclosure, a noise emitter mounted within the enclosure, a control circuit mounted within the enclosure, and an actuator extending externally of the enclosure, the actuator being designed to be plugged into a first actuator receptor on a towing vehicle or a second actuator receptor on the locking assembly, the noise emitter being activated when the actuator is unplugged from one of the receptors.
According to a further aspect of the present invention, there is provided a method for encouraging the use of an anti-theft locking assembly wherein the anti-theft locking assembly is mounted on a trailer on the connection between the trailer and a towing vehicle, comprising the steps of mounting a housing having a sound emitting device proximate the anti-theft assembly, the housing enclosing a control circuit and a noise emitter and an actuator extending externally thereof, the control circuit being operative to activate the noise emitter when the actuator is disconnected from a receptor, providing a first receptor on the anti-theft device, and providing a second receptor on the vehicle.
The device of the present invention is designed to be used primarily with a conventional towing vehicle/trailer combination. The towing vehicle may range from automobile to the cab of a semi-trailer. Similarly, the type of attachment between the

Figure 1 is a view of a portion of the trailer and vehicle connection with the anti-theft locking assembly in place;
Figure 2 is a view similar to Figure 1 illustrating the trailer connected to the vehicle;
Figure 3 is a view, partially in section, of the device according to the present invention; and Figure 4 is a perspective view of a portion of a trailer and vehicle utilizing the device.
DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings in greater detail and by reference characters thereto, there is illustrated in Figure 1 a truck generally designated by reference numeral 10 and which includes a fifth wheel generally designated by reference numeral 12.
Fifth wheel 12 comprises a base plate 14 which is secured to the truck 10. A
pair of support members 16 extend upwardly and support a coupling 18. Coupling 18 is of the known type including a horseshoe-shaped receptacle 19 and a locking bar 20.
A trailer 22 has a king pin (not shown) which engages with coupling 18. The above arrangement is a common one in the towing of trailers.
An anti-theft locking device 24 is mounted on the king pin of the trailer. In this respect, the anti-theft locking device may be such as shown in United States Patent 7,040,646 and which is commercially available from the company AMP Lock Inc., and which is illustrated on the web site www.amplock.com.
-4-Mounted on towing bar 23 of trailer 22 is a device generally designated by reference numeral 26. Device 26, as may be best seen in Figure 3, has a housing 28 which encloses a control circuit 30, a noise emitter 32 and a battery 34. Extending outwardly from housing 28 is an actuator 36.
Housing 28 is preferably of the tamper proof variety such that the regular user cannot gain access thereto. Many tamper proof housings are known in the art. It will be seen that the housing may contain vents to permit sound from noise emitter 32 to pass therethrough.
Battery 34 is of the long lasting type preferably a lithium ion battery which, under most circumstances, will have a life in excess of 10 years. Control circuit 30 functions such that when actuator 36 is not plugged into a suitable receptor, noise emitter 32 is activated.
In use, and as may be seen in Figures 1 and 2, when the trailer is hooked to the truck 10, actuator 36 is plugged into a vehicle receptor 38. However, when trailer 22 is disconnected, anti-theft locking device 24 must be connected to the king pin of trailer 22 such that actuator 36 may be plugged into a receptor 40 in locking assembly 24.
In other words, when the trailer is disconnected, it is necessary to remove actuator 36 from vehicle receptor 38 and noise emitter 32 is activated to remind the user to connect anti-theft locking device 24. Naturally, if so desired, a time delay may be built in to control circuit 30 so that the operator is given a certain amount of time to connect the anti-theft locking device without noise emitter 32 being activated.
As shown in Figure 4, a pick-up truck 50 having a ball hitch 52 could likewise use the device. Trailer tow bar 54 contains a device 26 which can be plugged into vehicle receptor 58. An anti-theft locking assembly (not shown) can be used with coupler 56.
It will be understood that various types of actuators and receptors may be utilized. In
