US 11,077,895 B2 · Portable trailer stands

Abstract

Example portable trailer stands for supporting parked trailers are disclosed herein. Some example portable trailer stands disclosed herein comprise two telescopic posts supporting a generally horizontal beam. Some examples include spring-loaded retractable wheels for selectively installing and removing the trailer stand from underneath a trailer left parked on a driveway. After being positioned under the trailer, the posts extend to lift the beam solidly up against the underside of the trailer. To accommodate conditions where the driveway is not parallel to the trailer's underside, some example posts can be lengthened independently and have angular play that allows the beam to tilt. In some examples, the horizontal axle of the trailer stand wheels is perpendicular to the beam so that the trailer stand can be readily installed from either the front or side of the trailer. Some examples have a kingpin-receiving groove in the beam or have some other kingpin-receiving feature.

Dependent claims

A portable trailer stand, comprising:

a first post;
a second post spaced apart from the first post, each of the first and second posts having a lower end and an upper end, the lower and upper ends of the first post defining a first distance, the lower and upper ends of the second post defining a second distance;
an elongate beam extending between the upper ends of the first and second posts, the first and second distances being adjustable to enable the elongate beam to selectively engage an underside of a trailer parked on a surface while the lower ends of the first and second posts engage the surface;
a lower beam extending between the first and second posts;
and
a wheel coupled to the first and second posts via the lower beam, the wheel having an adjustable height relative to the lower ends of the first and second posts, the wheel to extend below the lower ends of the first and second posts when the elongate beam is spaced apart from the underside of the trailer, the wheel to move relative to the lower ends of the first and second posts in a straight line extending perpendicular to the lower beam.

A portable trailer stand, comprising:

a first means for adjusting a height of the trailer stand, the first means for adjusting having a first lower end and a first upper end, a first distance between the lower and upper ends of the first means for adjusting being adjustable;
a second means for adjusting the height of the trailer stand, the second means for adjusting spaced apart from the first means for adjusting, the second means for adjusting having a second lower end and a second upper end, a second distance between the lower and upper ends of the second means for adjusting being adjustable;
a means for selectively engaging an underside of a trailer parked on a surface, the means for selectively engaging to extend between the first and second upper ends of the first and second means for adjusting, the first and second means for adjusting to engage the surface when the means for selectively engaging is engaging the underside of the trailer;
