## Abstract

A shock absorbing auxiliary wheel for a mobile home with a set of wheels positioned on a lower surface thereof. Further provided is at least one auxiliary wheel assembly positioned behind the wheels of the mobile home. The wheel assembly is adapted to engage the ground and absorb any shock associated with such engagement.

## Claims

### Claim 1

A new and improved shock absorbing auxiliary wheel mechanism for a mobile home comprising, in combination:
a mobile home having a plurality of longitudinal horizontally orientated supports and lateral horizontally orientated supports situated on a bottom surface thereof; and
at least two auxiliary wheel assemblies including:
a leaf spring having a lower strip with an inboard end and an outboard end each with an aperture formed therein and an upper strip with an inboard end coincident with the inboard end of the lower strip with an aperture formed therein and an outboard end extending a length 75% that of the lower strip,
a wheel bracket comprising a plate with an aperture formed therein for allowing the coupling thereof with the outboard end of the lower strip of the leaf spring, the wheel bracket having a fork extending therefrom on a side opposite the leaf spring with a pair of bores formed therein,
a wheel with a cylindrical configuration constructed from steel, the wheel including an axial bore formed therein for allowing an axle to be rotatably situated therein and coupled at opposite ends thereof between the bores of the fork and a rubber layer lining an outer surface of the entire wheel, and
a mounting bracket with an L-shaped configuration having a horizontally orientated extent situated on an upper surface of the inboard end of the upper strip with two pairs of spaced apertures formed in opposite sides thereof and a vertically orientated extent formed integral with the horizontally orientated extent with a pair of apertures formed adjacent a top edge thereof for allowing coupling with one of the longitudinal supports of the mobile home via a pair of bolts, the
mounting bracket further including a square plate situated on a lower surface of the inboard end of the lower strip with two pairs of spaced apertures formed in opposite sides thereof for allowing coupling with the apertures of the horizontally oriented extent of the mounting bracket via a pair of bolts;
whereby the wheels of the wheel assemblies are adapted to engage the ground and the leaf springs are adapted to absorb any shock associated with such engagement.

### Claim 2

A shock absorbing auxiliary wheel mechanism comprising:
a trailer with a set of wheels positioned on a lower surface thereof; and
at least one auxiliary wheel assembly positioned behind the wheels of the trailer, whereby the wheel assembly is adapted to engage the ground and absorb any shock associated with such engagement;
wherein each auxiliary wheel assembly includes a leaf spring having a lower strip with an inboard end and an outboard end each with an aperture formed therein and an upper strip with an inboard end coincident with the inboard end of the lower strip with an aperture formed therein;
wherein each auxiliary wheel assembly includes a wheel bracket comprising a plate with an aperture formed therein for allowing the coupling thereof with the outboard end of the lower strip of the leaf spring, the wheel bracket having a fork extending therefrom on a side opposite the leaf springs with a pair of bores formed therein.

### Claim 3

A shock absorbing auxiliary wheel mechanism comprising:
a trailer with a set of wheels positioned on a lower surface thereof; and
at least one auxiliary wheel assembly positioned behind the wheels of the trailer, whereby the wheel assembly is adapted to engage the ground and absorb any shock associated with such engagement;
wherein each auxiliary wheel assembly includes a leaf spring having a lower strip with an inboard end and an outboard end each with an aperture formed therein and an upper strip with an inboard end coincident with the inboard end of the lower strip with an aperture formed therein and an outboard end extending a length 75% that of the lower strip;
wherein each auxiliary wheel assembly includes a wheel bracket comprising a plate with an aperture formed therein for allowing the coupling thereof with the outboard end of the lower strip of the leaf spring, the wheel bracket having a fork extending therefrom on a side opposite the leaf springs with a pair of bores formed therein;
wherein each auxiliary wheel assembly includes a wheel with a cylindrical configuration constructed from steel, the wheel including an axial bore formed therein for allowing an axle to be rotatably situated therein and coupled at opposite ends thereof between the bores of the fork and a rubber layer lining an outer surface of the entire wheel.

### Claim 4 (depends on 3)

A shock absorbing auxiliary wheel mechanism for a trailer as set forth in claim 3 wherein each auxiliary wheel assembly includes mounting a bracket with an L-shaped configuration having a horizontally orientated extent situated on an upper surface of the inboard end of the upper strip with two pairs of spaced apertures formed in opposite sides thereof and a vertically orientated extent formed integral with the horizontally orientated extent with a pair of apertures formed adjacent a top edge thereof for allowing coupling with longitudinal supports of the trailer via a pair of bolts, the mounting bracket further including a square plate situated on a lower surface of the inboard end of the lower strip with two pairs of spaced apertures formed in opposite sides thereof for allowing coupling with the apertures of the horizontally oriented extent of the mounting bracket via a pair of bolts.
