Patent number: 4483550Abstract: A hitch pin for securing a towed vehicle to a towing vehicle comprising an elongated pin member having first and second ends and a radially extending collar formed therebetween and a bail member attached to the pin proximate one end thereof. A toroidal case containing a magnet and having a magnetically permeable material as a base is disposed about the pin between the collar and the bail. A compression-type helical spring surrounds the pin intermediate the case and the bail for normally urging the magnet case against the collar but allowing the case to be displaced against the force of the spring.Type: GrantFiled: July 27, 1983Date of Patent: November 20, 1984Inventor: Ronald F.

Patent number: 4443144Abstract: The invention provides a locking pin (G) comprising a loop (B) and means (R) for pivoting the loop on the locking pin so that said loop (B) may be brought back to surround the spindle (A) in which the locking pin is engaged so as to oppose removal of said locking pin. The pivoting means (R) comprise a mobile bearing (6) supported by two substantially parallel arms (8, 9), the assembly being such that in a "high" position the arms extend on a side which moves the bearing (6) to a maximum away from the opposite end (e) of the locking pin, whereas in a "low" position, said arms (8, 9) have rotated with respect to the "high" position. The locking pin may pass through the loop when the arms are in the "low" position but cannot pass through the loop when the arms are in the "high" position.Type: GrantFiled: December 15, 1981Date of Patent: April 17, 1984Inventor: Hubert Defrancq
