Abstract
A vehicle drawbar hammer strap assembly may be coupled to an implement tongue with a drawbar pin. A cross pin with a lever arm is operable to releasably hold the drawbar pin. A trigger is engagable with the tongue and the cross pin, and is pivotal from a latched position wherein it engages the cross pin and holds the cross pin in its locked position to an unlatched position wherein it is spaced apart from the cross pin. The tongue engages the trigger and pivot the trigger in an over-center manner from its latched to its unlatched position. The trigger includes a latch member attached to a wire form part which is pivotally coupled to the hammer strap. The latch member is engagable with the lever arm and with an end of the tongue.

A vehicle drawbar hammer strap assembly comprising:
- a vehicle drawbar;
- a hammer strap member attached to the vehicle drawbar, the vehicle drawbar and the hammer strap member being adapted to receive an implement tongue;
- a drawbar pin mountable to the vehicle drawbar and hammer strap member;
- a cross pin rotatably mounted in the hammer strap for operable engagement with the drawbar pin to releasably hold the drawbar pin in a mounted position, the cross pin having a lever arm manipulatable to rotate the cross pin to an unlocked position permitting insertion of the drawbar pin and to a locked position preventing movement of the drawbar pin;
- and
- a trigger pivotally coupled to the hammer strap member, the trigger being engagable with the tongue and the cross pin, the trigger being pivotal from a latched position wherein it engages the cross pin and holds the cross pin in its locked position to an unlatched position wherein it is spaced apart from the cross pin, insertion of the tongue into a space between the vehicle drawbar and the hammer strap causing the tongue to engage the trigger and pivot the trigger from its latched to its unlatched position.
A drawbar hammer strap assembly comprising:
- a drawbar hammer strap unit for attachment to a vehicle and being adapted to receive an implement tongue;
- a drawbar pin mountable to the drawbar hammer strap unit;
- a cross pin rotatably mounted in the drawbar hammer strap unit for operable engagement with the drawbar pin to releasably hold the drawbar pin in a mounted position, the cross pin having a lever arm manipulatable to rotate the cross pin to an unlocked position permitting insertion of the drawbar pin and to a locked position preventing movement of the drawbar pin;
- and and
- a latch member pivotally coupled to the drawbar hammer strap unit, the latch member having a first part for engaging the cross pin and having a second part engagable with the tongue, the latch member being pivotal from a latched position wherein the first part engages the cross pin and holds the cross pin in its locked position to an unlatched position wherein the first part is spaced apart from the cross pin to permit the cross pin to rotate to its unlocked position, insertion of the tongue into drawbar hammer strap unit causing the tongue to engage the second part and pivot the latch member from its latched to its unlatched position.
