House trailer stabilizer and jack system

Claim 2

A stabilizer for use beneath a house trailer or the like, said stabilizer comprising horizontally spaced first and second mounting brackets for securement to corresponding opposite side portions of a house trailer, a pair of downwardly divergent front and rear legs for each of said mounting brackets pivotally supported at their upper ends to the corresponding brackets for angular displacement about transverse axes extending between said mounting brackets, an elongated tension member extending between the lower ends of each pair of legs and pivotally secured thereto, one end of each tension member and the corresponding leg including means operative to releasably establish the pivot connection therebetween at a selected point of a plurality of predetermined points spaced along said one end of said tension member, and a diagonal brace means extending and connected between said pairs of legs.

Claim 3

The combination of claim 1 wherein the lower ends of said legs include enlarged foot members pivotally supported therefrom for oscillation about axes generally paralleling the first mentioned axes.

Claim 4

The combination of claim 1 wherein said front and rear legs of each pair of legs are pvivotally secured to the corresponding mounting brackets for oscillation about horizontally spaced apart front and rear axes, respectively.

Claim 5

The combination of claim 1 wherein said brace means includes a pair of crossed brace members secured between the upper and lower ends of said front legs and a second pair of crossed brace members extending and secured between the upper and lower ends of said rear legs.

Claim 6

The combination of claim 4 including means securing the crossed portions of each pair of crossed brace members together.

Claim 7

In combination with a mobile house trailer or the like including longitudinally extending opposite side marginal portions, a pair of first and second mounting brackets secured to corresponding portions of said side marginal portions, a pair of downwardly dIvergent front and rear legs for each of said mounting brackets pivotally supported at their upper ends to the corresponding brackets for angular displacement about transverse axes extending between said mounting brackets, an elongated tension member extending between the lower ends of each pair of legs and pivotally secured thereto, one end of each tension member and the corresponding leg including means operative to releasably establish the pivot connection therebetween at a selected point of a plurality of predetermined points spaced along said one end of said tension member, and diagonal brace means extending and connected between said pairs of legs, the lower ends of each pair of legs, when said one end of the corresponding tension member is released, being swingable upwardly to retracted positions disposed in generally horizontal positions, said tension members each being of a length to extend between the remote ends of the corresponding legs when they are horizontally disposed, said means operative to releasably establish said pivot connection also including means to secure said one ends of said tension members to the corresponding leg ends when said legs are horizontally disposed.

Claim 8

In combination with a mobile house trailer or the like including longitudinally extending opposite side marginal portions, a pair of first and second mounting brackets secured to corresponding portions of said side marginal portions, a pair of downwardly dIvergent front and rear legs for each of said mounting brackets pivotally supported at their upper ends to the corresponding brackets for angular displacement about transverse axes extending between said mounting brackets, an elongated tension member extending between the lower ends of each pair of legs and pivotally secured thereto, one end of each tension member and the corresponding leg including means operative to releasably establish the pivot connection therebetween at a selected point of a plurality of predetermined points spaced along said one end of said tension member, and diagonal brace means extending and connected between said pairs of legs, the lower ends of each pair of legs, when said one end of the corresponding tension member is released, being swingable upwardly to retracted positions disposed in generally horizontal positions, said tension members each being of a length to extend between the remote ends of the corresponding legs when they are horizontally disposed, said means operative to releasably establish said pivot connection also including means to secure said one ends of said tension members to the corresponding leg ends when said legs are horizontally disposed.

Claim 9

The combination of claim 6 wherein said side marginal portions each include means spaced in both directions therealong from the corresponding mounting bracket adapted to releasably engage and support the corresponding leg end when said legs are disposed in said retracted positions.

Claim 10

The combination of claim 1 wherein said brackets, legs and tension members are constructed of noncorrosive materials.
