Abstract
Disclosed is a landing gear including a leg, a foot, an indexing member, a mounting structure and a calibration structure. The leg extends downwardly in use and defines a longitudinal axis. The foot is operatively mounted to the leg for axial movement between a retracted position proximal to the leg and an extended position distal to the leg. The indexing member, in use, is operatively connected to the leg. The mounting structure, in use, is operatively connected to the foot. The calibration structure is connected to the mounting structure and, in use, extends axially alongside the leg. The landing gear can facilitate drop and pick-up of highway trailers.
Claims10
An improved trailer of the type for use with a tractor,
- the tractor being of the type having a fifth wheel movable between up and down positions,
- the trailer being of the type having:
- a wheeled carriage;
- a king pin mounted to and extending downwardly from the underside of the carriage for coupling with the fifth wheel;
- and
- a pair of landing gear, each of the pair including:
- an elongate leg extending downwardly from the underside of the carriage and defining a longitudinal axis;
- and
- a foot operatively mounted to the leg for longitudinal movement between a retracted position proximal to the leg and an extended position distal to the leg
- wherein the improvement comprises:
- an indexing member which, in use, is operatively connected to the leg;
- a mounting structure which, in use, is operatively connected to the foot;
- and
- a calibration structure connected to the mounting structure and which, in use, extends axially alongside the leg.
Apparatus comprising:
- a landing gear including:
- a leg which extends downwardly in use and defines a longitudinal axis;
- a foot operatively mounted to the leg for axial movement between a retracted position proximal to the leg and an extended position distal to the leg;
- an indexing member which, in use, is operatively connected to the leg;
- a mounting structure which, in use, is operatively connected to the foot;
- and
- a calibration structure connected to the mounting structure and which, in use, extends axially alongside the leg.
A kit for use with a variety of trailer-tow vehicle combinations,
- in each combination,
- the tow vehicle having one of a hitch and a hitch receiver;
- and
- the trailer having:
- the other of the hitch and the hitch receiver;
- and a landing gear, the landing gear including
- an elongate leg extending downwardly from the trailer and defining a longitudinal axis;
- and
- a foot operatively mounted to the leg for axial movement between a retracted position proximal to the leg and an extended position distal to the leg
- the kit comprising:
- an indexing member which, in use, is operatively connected to the leg of the landing gear of any one of the variety of trailers;
- a mounting structure which, in use, is operatively connected to the foot of said landing gear;
- a calibration structure:
- connected to the mounting structure;
- which, in use, extends axially alongside the leg of said landing gear;
- and having a plurality of axially-spaced securement locations associated therewith;
- and
- a marker adapted:
- to facilitate visual alignment of the marker and the indexing member;
- and for releasable connection to the calibration structure at any selected one of the securement locations,
- whereby
- in the context of the use of the kit with any one of the combinations, wherein
- the landing gear of the trailer of said combination has an operative configuration wherein the trailer is supported by the landing gear such that other of the hitch and hitch receiver is at a height optimized for engagement of the one of the hitch and hitch receiver therewith,
- the calibration structure has a sweet spot which is aligned with the indexing member when the landing gear is in the operative configuration,
- the marker can be secured to the one of the securement locations closest to the sweet spot to facilitate visual alignment of the sweet spot with the indexing member, thereby to approximate the operative configuration of the landing gear and facilitate engagement and disengagement of the hitch and hitch receiver.
