Abstract

An improved, stakeless livestock trailer includes sidewalls and a front wall constructed of stacked and interlocked extruded tubular members. In addition to forming the walls, the tubular members also form the exterior framework of the trailer, allowing a modular floor system to be attached directly to the sidewalls. The tubular members themselves have a unique tongue and groove interlocking structure which allows an adhesive to be inserted therebetween and which provides interior voids for excessive adhesive to collect during assembly. An improved gooseneck design eliminates the large support I beams required by prior art gooseneck designs, thus increasing storage space and/or increasing the clearance of an overhead storage compartment.

Claims

1. A vehicle body comprising:

a. a pair of vehicle sidewalls, each including a plurality of elongate tubular members, at least some of which are stacked atop each other and attached together via an adhesive, each said tubular member comprising;

i. at least one chamber with an inner wall and an outer wall;

ii. a channel formed by extensions of said inner and outer walls; and

iii. a tongue formed by extensions of said inner and outer walls and positioned on an opposite end of said tubular member from said channel, said tongue being sized for insertion in the channel of an adjacent one of said tubular members, the relative sizes of said tongue and said channel allowing space for the collection of said adhesive, wherein;

b. said vehicle comprises a trailer with a gooseneck assembly on the front thereof, said gooseneck assembly comprising;

i. a storage compartment having a front wall, sidewalls and upper and lower central support members;

ii. a vertical gooseneck removably connectable with a towing vehicle; and

iii. a buttress connected to and extending backward from said gooseneck to said front wall of said storage compartment, a rear surface of said buttress being connected to and extending substantially from top to bottom of said compartment front wall.

2. A trailer as in claim 1, said gooseneck assembly further comprising:

a. an upper bracket extending through said compartment front wall, said upper bracket connecting said buttress to said upper central support member;

b. a lower bracket extending through said compartment front wall, said lower bracket connecting said buttress to said lower central support member; and

wherein

c. said sidewalls comprise a plurality of stacked, connected tubular members.

3. A trailer comprising:

a. a trailer frame comprising a plurality of contiguous elongate metal tubular members which are stacked atop each other and attached together via an adhesive, said stacked tubular members also forming at least portions of two sidewalls and a front wall of said trailer, the lowermost ones of said stacked tubular members being substantially identical in cross section to the other tubular members; and

b. a floor system, said floor system comprising;

i. a plurality of modular floor members interconnected together to form said floor system;

ii. said modular floor members extending laterally across said trailer and terminal ends of said modular floor members being connected solely directly to the lowermost ones of said tubular members in said sidewalls.

4. A vehicle as in claim 3, wherein said adhesive comprises a modified acrylic structural adhesive.

5. A trailer as in claim 3, each said tubular member comprising:

a. at least one chamber with an inner wall and an outer wall;

b. a channel formed by extensions of said inner and outer walls; and

c. a tongue formed by extensions of said inner and outer walls and positioned on an opposite end of said tubular member from said channel, said tongue being sized for insertion in the channel of an adjacent one of said tubular members, the relative sizes of said tongue and said channel allowing space for the collection of said adhesive.

6. A trailer as in claim 5, wherein said tongue of each said tubular member comprises:

a. a surface with a width which is narrower than that of the channel, said surface extending approximately perpendicular to said inner and outer walls; and

b. said inner and outer walls tapering inward and then back outward below said surface to form a pair of grooves which extend longitudinally along the tubular member.

7. A vehicle as in claim 3, wherein each said modular floor member comprises:

a. a web with a top surface which forms an expanse of floor;

b. a downwardly directed hook member extending along one side of said web;

c. an upwardly directed receiving slot extending along a second side of said web, said slot being sized to mate with the hook member of an adjacent modular member to form a junction; and

d. at least one strengthening rib extending downward from a bottom surface of said web and running longitudinally along said modular floor member.

8. A trailer as in claim 3, said trailer including a gooseneck assembly on the front thereof, said gooseneck assembly comprising:

a. a storage compartment having a front wall, sidewalls and upper and lower central support members;

b. a vertical gooseneck removably connectable with a towing vehicle; and

c. a buttress connected to and extending backward from said gooseneck to said front wall of said storage compartment, a rear surface of said buttress being connected to and extending substantially from top to bottom of said compartment front wall.

9. A trailer as in claim 8, said gooseneck assembly further comprising:

a. an upper bracket extending through said compartment front wall, said upper bracket connecting said buttress to said upper central support member;

b. a lower bracket extending through said compartment front wall, said lower bracket connecting said buttress to said lower central support member; and

wherein

c. said sidewalls comprise a plurality of stacked, connected tubular members.

10. A trailer comprising:

a. a trailer frame comprising a plurality of contiguous elongate tubular members which are stacked atop each other and attached together via an adhesive, said stacked tubular members also forming at least a portion of two sidewalls and a front wall of said trailer, each said tubular member comprising;

i. at least one chamber with an inner wall and an outer wall;

ii. a channel formed by extensions of said inner and outer walls; and

iii. a tongue formed by extensions of said inner and outer walls and positioned on an opposite end of said tubular member from said channel, said tongue being sized for insertion in the channel of an adjacent one of said tubular members, the relative sizes of said tongue and said channel allowing space for the collection of said adhesive; and

b. a floor system, said floor system comprising;

i. a plurality of modular floor members interconnected together to form said floor system;

ii. said modular floor members extending laterally across said trailer, terminal ends of said modular floor members being connected directly to the lowermost ones of said tubular members in said sidewalls;

c. a gooseneck assembly on the front of said trailer, said gooseneck assembly comprising;

i. a storage compartment having a front wall, sidewalls and upper and lower central support members;

ii. a vertical gooseneck removably connectable with a towing vehicle; and

iii. a buttress connected to and extending backward from said gooseneck to said front wall of said storage compartment, a rear surface of said buttress being connected to and extending substantially from top to bottom of said compartment front wall.

11. A trailer as in claim 10, said gooseneck assembly further comprising:

a. an upper bracket extending through said compartment front wall, said upper bracket connecting said buttress to said upper central support member;

b. a lower bracket extending through said compartment front wall, said lower bracket connecting said buttress to said lower central support member; and

wherein

c. said sidewalls comprise a plurality of stacked, connected tubular members.

12. A trailer comprising:

a. a cargo compartment formed by a pair of vehicle sidewalls and a front wall;

b. a gooseneck assembly positioned on the front of said cargo compartment, said gooseneck assembly comprising;

i. a storage compartment having a front wall, sidewalls and upper and lower central support members;

ii. a vertical gooseneck removably connectable with a towing vehicle; and

iii. a buttress connected to and extending backward from said gooseneck to said front wall of said storage compartment, a rear surface of said buttress being connected to and extending substantially from top to bottom of said storage compartment front wall.

13. A trailer as in claim 12, said gooseneck assembly further comprising:

a. an upper bracket extending through said storage compartment front wall, said upper bracket connecting said buttress to said upper central support member;
