  • Patent number: 7591477
    Abstract: The system for capturing a vehicle is a device, which is mounted on the front of a first vehicle for deploying a grasping hook for grasping the rear bumper of a second vehicle. In operation, the system begins in a locked configuration, with a hook member being positioned rearward with respect to a lower shaft. When the first vehicle brings an actuating arm in contact with the rear bumper of the second vehicle, pressure on the actuating arm generates rotation in the upper shaft. This rotation of the upper shaft causes disengagement of the lower end of an engaging member from a recess formed in a disc mounted on the lower shaft, causing the resiliently biased lower shaft to rotate. Rotation of the lower shaft rotates an elongated hook support and the hook member into the deployed configuration, with the hook member grasping the rear bumper of the second vehicle.

  • Patent number: 5150911
    Abstract: An improved tow bar assembly used to tow cars or trailers located on uneven terrain. The assembly uses two tow bars. One end of each tow bar is attached to a bumper housing. Each bumper housing is removably clamped to the bumper of a disabled vehicle by a chain which has one end secured to the undercarriage of the vehicle and the other end engaged to a chain hook member. The chain is pulled tight by tightening wing nuts threaded onto the upper end of a bolt which causes a spring located between the wing nuts and the top of the bumper housing to pull the chain tight. A socket member located where the other ends of the tow bars join together engages a ball member mounted on a supporting structure of a tow vehicle providing a universal-type joint. The socket member is secured to the ball member by a rotating latch member which uses a pin to prevent the latch member from rotating relative to the socket member, effectively locking the socket member to the ball member.

    Abstract: The invention provides a hitch intended especially as a bumper hitch for automobiles and employing a pair of adjustable-length chains to connect the hitch to the bumper. The two chains are connected to the arms of a centrally-pivoted, two-armed lever and the lever pivot is moved backwards by a cam to tighten them simultaneously, with the lever pivoting to take up inequalities. The cam pivots about the lever pivot and engages a reaction member to produce the tightening movement, the cam having a "dead" position on tightening so that it will not move voluntarily out of that position. The hitches can be used in pairs on a transverse trailer-ball carrying bar which extends through the hitch bodies and also constitutes the reaction member for each hitch cam. The hitches are retained on the bar and slide freely thereon until the cam is moved to the tightened position, when it also locks the respective hitch in transverse position on the bar by its reaction engagement with the bar.

The curved arm assemblies lie in a lateral plane, with their convex surfaces facing each other, thereby allowing significantly improved clearance between the bumper of the towing vehicle and the arm assemblies themselves. At the distal ends of the curved arm assemblies are three distinct bumper engagement means, including a lower bumper clamping chain which is tensioned against an upper bumper clamp, together with a redundant tensioning through a safety chain attached to the frame of the towed vehicle. At the distal ends of the curved arm assemblies there is further provided a spreader bar assembly, which both adjustably maintains the bumper mounting assemblies in position, and adds significantly increased overall rigidity to the entire towbar assembly.
