Abstract
In an example, an adaptor for a lift jack may include a first section having an opening to receive a ring attached to a vehicle and a second section connected to the first section, in which the second section includes a space to receive a runner support of a lift jack runner. The adaptor may also include a locking hook rotatably connected to the second section, in which the locking hook is to latch onto the ring when the runner support is inserted into the space in the second section.
Claims16
An adaptor for a lift jack, said adaptor comprising:
- a first section having an opening to receive a ring attached to a vehicle;
- a second section connected to the first section, wherein the second section includes a space to receive a runner support of a lift jack runner and the second section has a smaller width as compared with a width of the first section;
- a locking hook rotatably connected to the second section, wherein the locking hook is to move between an unlocked position and a locked position, and wherein the locking hook is to move to the locked position and latch onto the ring through contact with the runner support as the runner support is inserted into the space in the second section;
- and
- a tension spring connected to the locking hook, wherein the tension spring is to bias the locking hook into the unlocked positioned.

An adaptor for a lift jack, said adaptor comprising:
- a body having a first section and a second section, wherein the first section and the second section are formed of a single piece of material, wherein the first section has an opening, and wherein the second section includes two coextensive segments extending from the first section;
- a pin extending between the coextensive segments of the second section;
- a latching mechanism rotatably connected to the pin, wherein the latching mechanism includes a locking hook that is to rotate between a first position and a second position, wherein the first position is a position in which the locking hook is outside of the opening and the second position is a position in which the locking hook is within the opening;
- and
- a spring connected to the latching mechanism, wherein the spring is biased to maintain the latching mechanism in the first position, wherein insertion of a runner support between the coextensive segments causes the runner support to contact the latching hook and cause the latching hook to rotate into the second position at which the latching hook is latched onto a tow ring of a vehicle and wherein the spring is to cause the latching hook to be unlatched from the tow ring when the runner support is removed from between the coextensive segments.

A method of implementing a lift jack adaptor, said method comprising:
- providing a lift jack adaptor comprising:
- a first section having an opening;
- a second section connected to the first section, wherein the second section includes a space and the second section has a smaller width as compared with a width of the first section;
- a locking hook rotatably connected to the second section, wherein the locking hook is to move between an unlocked and a locked position;
- and
- a tension spring connected to the locking hook, wherein the tension spring is to bias the locking hook into the unlocked position;
- positioning the lift jack adaptor on a tow ring attached to a vehicle to cause the tow ring to be inserted into the opening in the first section;
- and
- inserting a runner support of a lift jack into the space of the second section of the adaptor, wherein the second section includes a pair of segments that are spaced apart from each other and includes features to securely contact the runner support, wherein the locking hook is rotatably attached to the pair of segments, and wherein insertion of the runner support causes the locking hook to rotate from the unlocked position to the locked position, wherein the locked position is a position in which the locking hook latches onto the tow ring.
