Abstract
Abstract A trailer for transporting a prefabricated section of a building, which section includes a roof bridging at least two sidewalls, one mounted near the rear of the trailer and the other near the front of the trailer. The trailer includes front, middle and rear frame portions. A towing connection is mounted on the front frame portion, the building section is supported on the middle portion and the trailer wheels are attached below the rear portion. Each sidewall of the building section is supported in the cavity of a channel beam which is welded to the upper surface of a crossbeam; the two crossbeams bridge across and are attached to one or more longitudinal beams which extend the full length of the trailer between the two sidewalls of the building. The joined longitudinal beams and crossbeams form a support section which comprises the middle frame portion. A vertical offset between the middle and rear frame portions allows the top of the generally rectangular midddle section to be below the top of the wheels mounted to its rear. According to one embodiment, the longitudinal beam or beams are formed in readily separable sections so that the overall length of the trailer can be varied.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
334 words
In the combination of a trailer and a prefabricated section of a building, said building including a roof bridging at least two sidewalls, one sidewall being located near the front of the trailer and the other being loCated near the rear of the trailer, a plurality of supporting wheels mounted beneath the rear portion of the trailer and a towing connection mounted on the front portion of said trailer, frame means comprising the middle portion of the trailer extending between the front and rear portions, said frame including (1) at least two longitudinally positioned beams extending the full length between the two building sidewalls and (2) two crossbeams bridging across and connected to the ends of the longitudinal beams and extending transversely thereto, means for mechanically connecting the building section to the middle portion of the trailer to prevent relative movement between the two, the improvement comprising: said mechanical connecting means comprising (1) a plurality of vertically extending prongs mounted on one of the building section and the middle portion of the trailer and (2) a plurality of mating brackets with apertures mounted on the other, said prongs and apertures being located such that the prongs project through the apertures when the building endwalls rest on the trailer, each of the crossbeams lying in a plane which is coextensive with one of the sidewalls located near the front or rear of the trailer, said crossbeams being the sole direct load-bearing portions of the trailer, channel members joined to the top surface of each of said crossbeams with the legs of said channels projecting vertically to serve as a trough for the sidewalls of said building section to prevent gross relative longitudinal movement between the two but without any rigid mechanical connection, and off-setting means between the rear-most crossbeam and rear portion of the trailer, said off-setting means being for allowing the bottom of the housing sidewalls to rest in the channel, the supporting surface of which is below the upper surface of the wheels.
Claim 2
Dependent Claim
334 words
In the combination of a trailer and a prefabricated section of a building, said building including a roof bridging at least two sidewalls, one sidewall being located near the front of the trailer and the other being loCated near the rear of the trailer, a plurality of supporting wheels mounted beneath the rear portion of the trailer and a towing connection mounted on the front portion of said trailer, frame means comprising the middle portion of the trailer extending between the front and rear portions, said frame including (1) at least two longitudinally positioned beams extending the full length between the two building sidewalls and (2) two crossbeams bridging across and connected to the ends of the longitudinal beams and extending transversely thereto, means for mechanically connecting the building section to the middle portion of the trailer to prevent relative movement between the two, the improvement comprising: said mechanical connecting means comprising (1) a plurality of vertically extending prongs mounted on one of the building section and the middle portion of the trailer and (2) a plurality of mating brackets with apertures mounted on the other, said prongs and apertures being located such that the prongs project through the apertures when the building endwalls rest on the trailer, each of the crossbeams lying in a plane which is coextensive with one of the sidewalls located near the front or rear of the trailer, said crossbeams being the sole direct load-bearing portions of the trailer, channel members joined to the top surface of each of said crossbeams with the legs of said channels projecting vertically to serve as a trough for the sidewalls of said building section to prevent gross relative longitudinal movement between the two but without any rigid mechanical connection, and off-setting means between the rear-most crossbeam and rear portion of the trailer, said off-setting means being for allowing the bottom of the housing sidewalls to rest in the channel, the supporting surface of which is below the upper surface of the wheels.
Claim 3
Dependent Claim
53 words
The combination of claim 1 wherein the frame includes two of said longitudinally extending beams which constitute sidebeams, and wherein standard 10 inch channels are its sidebeams and crossbeams and the tops of said 10 inch beams are no higher than about 20 inches from the surface of level ground beneath the wheels.
