Abstract

Abstract The trailer frame parts (26, 28) are hingedly secured to a main beam (40). Axle (42) and stabilizing bars (44) maintain the structure in the unfolded position. When desired, the unit can be folded by swivelling the axle (42) and frame parts (26, 28), moving the frame parts (24) laterally inwardly towards the main beam (40).

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 258 words
A folding tiltable trailer suitable for towing by a motor vehicle comprising: an elongated frame member (25) having means (14) for connecting the trailer to the motor vehicle at one end thereof; a main beam (40) hingedly secured to said frame member (25) and tiltable relative to said frame member (25); a trailer bed (10) side frames (24) on either side of said main beam (40) spaced therefrom and positioned parallel thereto adapted to receive said trailer bed (10), characterised in that there are provided panel members (26,28) hingedly attaching said side frames (24) to said main beam (40) at the forward and rear ends of said main beam; a pivotable axle (42) is positioned beneath said main beam (40) and perpendicular thereto extending to said side frames (24), said axle (42) being pivotally secured (92) at one end (80) to one of the side frames (24) and releasably secured (118,120) at the other end (102) to the other of said side frames (24), said axle (42) being pivotable to a position where it is parallel to the main beam (40); and wheels (47) known per se attached to the ends of said axle means (42), whereby upon removal of the bed (10), the axle means (40) is pivoted to a position parallel to the main beam (40) and the wheels (47) are drawn inwardly to a position adjacent said main beam (40), said panel members (26,28) swinging forwardly to permit the side panels (24) to also approach the main beam (40) thereby forming a compact, elongated assembly.
Claim 2
Dependent Claim 258 words
A folding tiltable trailer suitable for towing by a motor vehicle comprising: an elongated frame member (25) having means (14) for connecting the trailer to the motor vehicle at one end thereof; a main beam (40) hingedly secured to said frame member (25) and tiltable relative to said frame member (25); a trailer bed (10) side frames (24) on either side of said main beam (40) spaced therefrom and positioned parallel thereto adapted to receive said trailer bed (10), characterised in that there are provided panel members (26,28) hingedly attaching said side frames (24) to said main beam (40) at the forward and rear ends of said main beam; a pivotable axle (42) is positioned beneath said main beam (40) and perpendicular thereto extending to said side frames (24), said axle (42) being pivotally secured (92) at one end (80) to one of the side frames (24) and releasably secured (118,120) at the other end (102) to the other of said side frames (24), said axle (42) being pivotable to a position where it is parallel to the main beam (40); and wheels (47) known per se attached to the ends of said axle means (42), whereby upon removal of the bed (10), the axle means (40) is pivoted to a position parallel to the main beam (40) and the wheels (47) are drawn inwardly to a position adjacent said main beam (40), said panel members (26,28) swinging forwardly to permit the side panels (24) to also approach the main beam (40) thereby forming a compact, elongated assembly.
Claim 3
Dependent Claim 61 words
A trailer as claimed in Claim 1, wherein said other end (102) of said axle (42) is provided with a locking yoke (118,120) and said other end of said side frames (24) includes a bracket (79) having a flanged portion for receiving said yoke (120) therein, said yoke (120) including means (118) for releasably securing said yoke (120) to said bracket(79).
Claim 4
Dependent Claim 80 words
A trailer as claimed in Claim 1 or Claim 2, further including stabilizer bars (44) connecting said side panels (24) to said main beam (40) to add rigidity to said trailer, each of said bars (44) being pivotally connected (66,64) to said main beam (40) and one of said side panels (24) at an acute angle relative to said main beam (40) whereby during collapsing of said trailer said bars (44) pivot to positions parallel to said main beam (40).
Claim 5
Dependent Claim 33 words
A trailer as claimed in any one of Claims 1 to 3, wherein said side panels (24) and said panel members (26,28) include a channel (70,72,74) adapted to support said bed (10) therein.
Claim 6
Dependent Claim 36 words
A trailer as claimed in any one of Claims 1 to 4, further including removable sideboards (12) and wherein said side panels (24) and panel members (26,28) include means (30) for securing said sideboards (12) thereto.
