Abstract
A jack for use with a towed vehicle is disclosed. The jack may include a first housing, a pair of cam surfaces, and a second housing telescopically moveable relative to the first housing. The jack may also include a pair of engaging members positionable to a first position generally inhibiting relative telescopic movement between the first and second housings and a second position generally not inhibiting relative telescopic movement between the first and second housings, and a handle attached to the engaging members, where the handle is selectively positionable along the cam surfaces positioning the engaging members to the first and second positions.
Claims35
A jack comprising:
- a first housing having a pair of apertures;
- a pair of cam surfaces;
- a second housing telescopically moveable relative to the first housing, the second housing having a plurality of pairs of apertures;
- a pair of engaging members positionable to a first position extending into the apertures of the first housing and at least one of the pair of apertures of the second housing generally inhibiting relative telescopic movement between the first and second housings and a second position allowing relative telescopic movement between the first and second housings;
- and
- a handle attached to the engaging members, wherein the handle is selectively positionable along the cam surfaces to a first handle position positioning the engaging members to the first positions and a second handle position positioning the engaging members to the second position, whereby the handle is generally prevented from moving to the first handle position until the engaging members are in the first position.

A jack comprising:
- a housing having a pair of apertures;
- a drop leg telescopingly moveable relative to the housing along an axis, wherein the drop leg includes at least a pair of apertures;
- a pair of cam surfaces;
- a pair of engaging members operatively attached with the housing;
- and
- a handle attached to the engaging members, the handle positionable along the cam surfaces to of positively drive the engaging members in a first direction engaging the apertures of the housing and the apertures of the drop leg and in a second direction disengaging the apertures of the drop leg.

A jack comprising:
- a housing having a pair of apertures;
- a drop leg operatively engaged with the housing, wherein the drop leg includes a plurality of apertures;
- a pair of guide members attached to the housing;
- a pair of engaging members positioned within the guide members;
- a handle having a pair of first and second ends, the second ends attached to the engaging members, the handle capable of being selectively positioned, wherein selective positioning of the handle engages or disengages the engaging members with the apertures of the housing and a pair of the plurality of apertures of the drop leg;
- and
- wherein the first ends of the handle are moveable relative to one another during selective positioning of the handle.
