Vehicle trailer

Claim 2

A trailer structure comprising: a pair of substantially parallel runner members, brace means interconnecting said runner members and holding them in spaced relationship, triangular tongue means having a base portion and two side portions extending from said base portion to the apex of the triangle formed thereby, the apex of said tongue means being adapted for connection to a towing vehicle, means for pivotally connecting the base portion of said tongue member to each of said runners, thereby enabling the tilting of said runners relative to said tongue member, a pair of wheel members, an axle interconnecting said wheel members, and means for connecting said axle to said runner members comprising a pair of bracket members having first and second mutually orthogonal flat bar portions, the first of said flat bar portions having apertures formed therein, said runners having apertures formed therein spaced to mate with said bar portion apertures, the ends of said runners having lip portions which abut and rest against the ends of the second of said bar portions, means for removably attaching said bracket members to said runners at one of several predetermined positions along the longitudinal extent thereof including bolts fitted through selected ones of said apertures, and spring means for resiliently suspending said axle from said bracket members.

Claim 3

The trailer structure of claim 1 wherein said runners have outwardly angulated side wall portions running along the opposite edges thereof, the wall portions on the outer edges of said runners extending substantially higher than those on the inner edges thereof.

Claim 4

The trailer structure of claim 2 and further including angulated elongated bar members attached to said side wall portions to form hollow triangular reinforcement members along the runner edges.

Claim 5

The trailer structure of claim 1 wherein said means for pivotally connecting the base portion of the tongue member to each of said runner members comprises a pair of hinge members.

Claim 6

The trailer structure of claim 4 and further including means for selectively preventing pivotal motion of said tongue member relative to said runners, comprising sleeve members attached respectively to said runners and said tongue member and bolt members fitted through said sleeve members.

Claim 7

A trailer structure comprising: a pair of substantially parallel runner members, said runners having outwardly angulated side wall portions running along the opposite edges thereof, the wall portions on the outer edges of said runners extending substantially higher than those on the inner edges thereof, angulated elongated bar members attached to said runner side wall portions to form hollow triangular reinforcement members therealong, brace means interconnecting said runner members and holding them in spaced relationship, triangular tongue means having a base portion and two side portions extending from said base portion to the apex of the triangle formed thereby, the apex of said tongue means being adapted for connection to a towing vehicle, means for pivotally connecting the base portion of said tongue member to each of said runners, thereby enabling the tilting of said runners relative to said tongue member, a pair of wheel members, an axle interconnecting said wheel members, means for connecting said axle to said runners, and brace members attached to the bottoms of said runner members and extending along substantially the entire length thereof, said brace members having a hat-shaped cross section tapered from the center towards the ends thereof.

Claim 8

A trailer structure comprising: a pair of substantially parallel runner members, said runners having outwardly angulated side wall portions running along the opposite edges thereof, the wall portions on the outer edges of said runners extending substantially higher than those on the inner edges thereof, angulated elongated bar members attached to said runner side wall portions to form hollow triangular reinforcement members therealong, brace means interconnecting said runner members and holding them in spaced relationship, triangular tongue means having a base portion and two side portions extending from said base portion to the apex of the triangle formed thereby, the apex of said tongue means being adapted for connection to a towing vehicle, means for pivotally connecting the base portion of said tongue member to each of said runners, thereby enabling the tilting of said runners relative to said tongue member, a pair of wheel members, an axle interconnecting said wheel members, means for connecting said axle to said runners, and brace members attached to the bottoms of said runner members and extending along substantially the entire length thereof, said brace members having a hat-shaped cross section tapered from the center towards the ends thereof.

Claim 9

A trailer structure for carrying a vehicle for towing comprising: a pair of substantially parallel runners having outwardly angulated sidewall portions running along the edges thereof, cross brace members holding said runners in spaced relationship, one of said brace members extending across the front edges of said runners and having a vertical portion forming a front stop, a triangular tongue member having a base portion and two arm portions, hinge means for pivotally connecting the opposite ends of said tongue member base portion to said runners to enable tilting motion of said runners relative to said tongue member for loading and unloading the vehicle, means for preventing pivotal motion of said runners relative to said tongue member with the runners in a towing position comprising first sleeves attached to the brace member extending across the front edges of said runners, second sleeves attached to said tongue member and bolts fitted through corresponding ones of said first and second sleeves to hold them together, a pair of wheel members, an axle interconnecting said wheel members, means for connecting said axle to said runners comprising a bracket connected to each end of said axle and means for removably attaching each of said brackets to an associated one of said runners at a selected position therealong, angulated elongated bar members attached to the runner side wall portions to form hollow triangularly cross sectioned members extending along the runner edges, and brace members attached to the bottoms of said runners and extending along substantially the entire length thereof, said brace members having a hat-shaped cross section tapered from the center towards the ends thereof.

Claim 10

A trailer structure for carrying a vehicle for towing comprising: a pair of substantially parallel runners having outwardly angulated sidewall portions running along the edges thereof, cross brace members holding said runners in spaced relationship, one of said brace members extending across the front edges of said runners and having a vertical portion forming a front stop, a triangular tongue member having a base portion and two arm portions, hinge means for pivotally connecting the opposite ends of said tongue member base portion to said runners to enable tilting motion of said runners relative to said tongue member for loading and unloading the vehicle, means for preventing pivotal motion of said runners relative to said tongue member with the runners in a towing position comprising first sleeves attached to the brace member extending across the front edges of said runners, second sleeves attached to said tongue member and bolts fitted through corresponding ones of said first and second sleeves to hold them together, a pair of wheel members, an axle interconnecting said wheel members, means for connecting said axle to said runners comprising a bracket connected to each end of said axle and means for removably attaching each of said brackets to an associated one of said runners at a selected position therealong, angulated elongated bar members attached to the runner side wall portions to form hollow triangularly cross sectioned members extending along the runner edges, and brace members attached to the bottoms of said runners and extending along substantially the entire length thereof, said brace members having a hat-shaped cross section tapered from the center towards the ends thereof.
