Abstract
Abstract A folding trailer is provided having a chassis supported by at least one pair of road wheels and a load bearing platform supported by the chassis, the load bearing platform being formed in two sections which are foldable between a first position in which the sections lie in a common plane and a second position in which the sections lie juxtaposed in parallel planes. When in the second position the trailer can be moved into a substantially vertical plane for stowage.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
197 words
A trailer comprising: a load bearing section comprised of a front part and a rear part; a pair of wheels disposed in coaxially spaced relationship to each other and operatively connected to said load bearing section to support said load bearing section in a substantially horizontal towing configuration; and a draw bar projecting beyond the front of said load bearing section substantially perpendicular to the axis of said wheels to enable engagement of said trailer with a towing vehicle, said load bearing section being foldable between a first position in which said two parts lie in a substantially common plane and a second position in which said two parts are juxtaposed in substantially parallel planes, said axis being so located to permit said load bearing section when in said second position to be supported by said wheels in a substantially horizontal configuration and to be moved to a substantially vertical configuration in which vertical configuration said load bearing section is substantially supported by an end of said front or rear part, said draw bar being pivotally associated with said load bearing section rearward of said axis when said load bearing section is in the substantially horizontal configuration.
Claim 2
Dependent Claim
197 words
A trailer comprising: a load bearing section comprised of a front part and a rear part; a pair of wheels disposed in coaxially spaced relationship to each other and operatively connected to said load bearing section to support said load bearing section in a substantially horizontal towing configuration; and a draw bar projecting beyond the front of said load bearing section substantially perpendicular to the axis of said wheels to enable engagement of said trailer with a towing vehicle, said load bearing section being foldable between a first position in which said two parts lie in a substantially common plane and a second position in which said two parts are juxtaposed in substantially parallel planes, said axis being so located to permit said load bearing section when in said second position to be supported by said wheels in a substantially horizontal configuration and to be moved to a substantially vertical configuration in which vertical configuration said load bearing section is substantially supported by an end of said front or rear part, said draw bar being pivotally associated with said load bearing section rearward of said axis when said load bearing section is in the substantially horizontal configuration.
Claim 3
Dependent Claim
35 words
A trailer as claimed in claim 1 further including releasable catch means to prevent pivotal movement of said draw bar with respect to said load bearing section when said trailer is in the operative position.
Claim 4
Dependent Claim
42 words
A trailer as claimed in claim 1, wherein said two parts comprise a front part and a rear part and wherein said front part is fixed with respect to said wheels and said rear part is pivotally connected to said front part.
Claim 5
Dependent Claim
19 words
A trailer as claimed in claim 3 wherein the pivot between said two parts lies above said common plane.
Claim 6
Dependent Claim
46 words
A trailer as claimed in claim 1 or claim 3, further including side board parts provided on the longitudinal edges of said load bearing platform and a toe board and a tail board provided on the front and rear edges, respectively, of said load bearing section.
Claim 7
Dependent Claim
38 words
A trailer as claimed in claim 5 wherein said side board parts and said toe and tail boards are foldable between erected positions substantially perpendicular to said common plane and folded position substantially parallel to said common plane.
Claim 8
Dependent Claim
28 words
A trailer as claimed in claim 6 further including means to lock said side board parts and said toe and tail boards in said erected and folded positions.
Claim 9
Dependent Claim
38 words
A trailer as claimed in claim 7 wherein said toe and tail boards are mounted so as to lock said side board parts in the folded position when said toe and tail boards are in the folded position.
Claim 10
Dependent Claim
54 words
A trailer as claimed in claim 8 wherein a means to lock said toe and tail boards in the folded position is provided in part by means which lock said toe and tail boards to said side boards when said toe and tail boards and said side board parts are in the erected position.
Claim 11
Dependent Claim
73 words
A trailer as claimed in claim 9 wherein catch means are provided on said side board parts to engage with lugs projecting from the adjacent toe or tail board when said side board parts and said toe and tail boards are in the erected position and wherein when said toe and tail boards are in the folded position said lugs are engaged with hooks projecting from said parts of said load bearing section.
Claim 12
Dependent Claim
21 words
A trailer as claimed in claim 6, further including means to lock said load bearing platform sections in said second position.
Claim 13
Dependent Claim
52 words
A trailer as claimed in claim 11, wherein said means to lock said parts of said load bearing section in said second position comprises means projecting from the rear section when in said second position so as to lie beneath said toe board when said toe board is in the folded position.
Claim 14
Dependent Claim
83 words
A trailer as claimed in claim 1, wherein said draw bar is provided in two parts, a first draw bar part being pivotally mounted with respect to said load bearing section and a second draw bar part being pivotally connected to said first draw bar part such that when said load bearing section is in a substantially vertical configuration, said second draw bar part can be pivoted to enable the distal end thereof to contact the surface on which said trailer is supported.
Claim 15
Dependent Claim
27 words
A trailer as claimed in claim 1, further including a chassis between said load bearing section and said wheels, said draw bar being mounted on said chassis.
