Truck bed lock

摘要

A truck bed lock that includes an outer shell, an inner casing disposed therein, and an internal shaft within the inner casing. A locking rod slidingly engages the internal shaft and a bottom compartment in the inner casing beneath the internal shaft. A quartet of spring-loaded legs, pivotably attached to a base of the locking rod, are maintained in a retracted position within the bottom compartment when the locking rod is extended for insertion through a hole in each of a tool box and a truck bed. Thereafter, the locking rod is retracted into the internal shaft and thereupon, the legs extend through a lower opening in the bottom compartment into a locked position parallel to a lower end of the outer shell with the legs being co-planar with one another adjoining the base of the locking rod to secure the tool box against the truck bed.

主权项

1. A truck bed lock comprising:
an outer shell having an upper end and a lower end, the outer shell further having a diameter; an inner casing disposed mostly within the outer shell, the inner casing having an top end and a bottom end, a portion of the top end extending outwardly from the upper end of the outer shell; an internal shaft centrally disposed within the inner casing, the internal shaft having an upper edge and a lower edge; a locking rod having an uppermost end and a lowermost end, the locking rod being centrally disposed along a longitudinal midline axis of the internal shaft, the uppermost end being extendible through the upper edge of the internal shaft; a bottom compartment centrally disposed within the inner casing in a position beneath the internal shaft, the bottom compartment having a lower opening, the lowermost end of the locking rod being extendible from the bottom compartment lower opening; a base disposed on the lowermost end of the locking rod; a plurality of spring-loaded legs pivotally attached to the base; a spring-loaded pivot mechanism disposed on each of the legs proximal the locking rod; an upper spring support fixedly attached to the locking rod; a tension second spring disposed within the internal shaft between the lower edge of the internal shaft and the upper spring support in a position surrounding the locking rod; wherein the second spring is configured to maintain the locking rod in an extended position, wherein in a fully extended position of the locking rod the second spring is wedged against the lower edge of the internal shaft and the upper spring support is attached to a set position on the locking rod and wherein the legs are disposed in a retracted position within the bottom compartment; wherein the legs are disposed in the retracted position within the bottom compartment upon disposition of the locking rod in the fully extended position in which the locking rod is extended away from the top end of the inner casing; and wherein the legs are disposed outside of the bottom compartment in an extended position in which the legs are disposed in a position parallel to the bottom end against the base upon the retraction of the locking rod into the internal shaft.
