The invention concerns a road trailer whose frame consists of profiles having a fin to support the floor and grooves on their upper and lower faces able to retain in rotation bolt heads and the lower edges of sidewalls (10). The side members and cross bars are joined by corner pieces which have a vertical orifice to receive the lower end of a post (9) comprising orthogonal grooves housing the side edges of the sidewalls (10). The corner pieces (30) have two perpendicular arms respectively fitted into the adjacent ends of profiles forming the frame. Mounting of the elements requires little tooling.

The invention claimed is: 1. A road trailer intended to be towed by a motor vehicle and comprising at least one cross axle (2) connected to two wheels (3) by two side suspension arms 19, a tongue (4) to hitch it to the vehicle, a body (6) mounted on the axle and the tongue and having a rectangular
The invention claimed is: 1. A road trailer intended to be towed by a motor vehicle and comprising at least one cross axle (2) connected to two wheels (3) by two side suspension arms 19, a tongue (4) to hitch it to the vehicle, a body (6) mounted on the axle and the tongue and having a rectangular frame (7) supporting a floor (8) and sidewalls (10), said frame having two parallel side members (11a, 11b), a front cross bar (12) and a rear cross bar (13), characterized by the fact that the side members (11a, 11b) and cross bars (12, 13) are made from metal profiles (14) and are joined at their adjacent ends by means of corner pieces (30) having two perpendicular arms (31a, 31b) which respectively fit into said adjacent ends and which also have through orifice (35) perpendicular to the plane of said arms, said side members (11a, 11b) and said cross bars (12, 13) comprising on their inner face a fin (20) which extends inwardly towards the inside of the frame (7) and which is intended to support the floor (8), and on their lower and upper faces a groove (15a, 15b) leading into a channel (16a, 16b) and able to receive and immobilize in rotation bolt heads (17) and the lower edges of the sidewalls, and by the fact that it also comprises four tubular corner posts (9) whose lower ends fit into the orifices (35) of the corner pieces (30), said posts (9) having two vertical grooves (51a, 51b), in orthogonal planes, intended to receive the side edges of sidewalls (10), and wherein said posts (9) are made from a profile (50) having two orthogonal grooves (51a, 51b) and are equipped at their lower end with an assembly piece (40) for assembling onto a corner piece (30), the assembly piece (40) having a lower part (40a) which fits into the orifice (35) of a corner piece (30) and an upper part (40b) which fits into the lower end of a profile (50) of a post (9), and wherein the assembly piece (40) comprises angle positioning means (41, 47) and clipping means (43a, 43b, 48a, 48b) which respectively cooperate with conjugate angle positioning means (42, 55) and clipping means (57a, 57b) provided on the corner pieces (30) and the lower ends of the post profiles (9). 2. Trailer as in claim 1, characterised by the fact that the angle positioning means comprise a vertical groove (42, 47) provided on one of the pieces and a protuberance (41, 55) provided on the other piece. 3. Trailer as in claim 1 or 2, characterised by the fact that the clipping means comprise a protuberance (48a) formed on an elastic tongue (49a) of the assembly piece (40) and which is able to enter into a hole (57a, 57b) or slot provided in the post profile (9) or corner piece (30). 4. A road trailer intended to be towed by motor vehicle and comprising at least one cross axle (2) connected to two wheels (3) by two side suspension arms 19, a tongue (4) to hitch it to the vehicle, a body (6) mounted on the axle and the tongue and having a rectangular frame (7) supporting a floor (8) and sidewalls (10), said frame having two parallel side members (11a, 11b), a front cross bar (12) and a rear cross bar (13), characterized by the fact that the side members (11a, 11b) and cross bars (12, 13) are made from metal profiles (14) and are joined at their adjacent ends by means of corner pieces (30) having two perpendicular arms (31a, 31b) which respectively fit into said adjacent ends and which also have through orifice (35) perpendicular to the plane of said arms, said side members (11a, 11b) and said cross bars (12, 13) comprising on their inner face a fin (20) which extends inwardly towards the inside of the frame(7) and which is intended to support the floor (8), and on their lower and upper faces a groove (15a, 15b) leading into a channel (16a, 16b) and able to receive and immobilize in rotation bolt heads (17) and the lower edges of the sidewalls, and by the fact that it also comprises four tubular corner posts (9) whose lower ends fit into the orifices (35) of the corner pieces (30), said posts (9) having two vertical grooves (51a, 51b), in orthogonal planes, intended to receive the side edges of sidewalls (10), wherein the sidewalls (10) include a lower edge, the lower edge (70) including means (71) able to slide within the upper groove (15b) of a side member (11a, 11b) or cross bar, during assembly. 5. Trailer as in claim 4, characterised by the fact that the sidewalls are made in a sheet metal formed to have rigidifying horizontal ripples (72a). 6. Trailer as in claim 4, characterised by the fact that the sidewalls are made from a plurality of profiles which fit into each other one above the other. 7. Trailer as in claim 4, characterised by the fact that the sidewalls are made from wood panels which fit into a groove (74) provided in the upper part of sliding means in the upper groove of the side members or cross bars. 8. Trailer as in claim 7, characerised by the fact that the sliding means are made from a profile (75). 9. Trailer as in claim 8, characterised by the fact that the side members on their inner face below the grooves comprise a plurality of openings to receive the ends of intermediate cross bars. 10. Trailer as in claim 9, characerised by the fact that the side members (11a, 11b) are reinforced by longitudinal beams (80a, 80b) arranged either side of the axle under said side members and fixed to the latter by bolting, said beams (80a, 80b) being integral with an axle plate (81) designed to form a single beam under the platform of said trailer. 11. Trailer as in claim 10, characterised by the fact that the sidewalls (10, 10a) and posts (9) are removable. 12. Trailer as in claim 11, characerised in that said through orifices (35) of frame (7) of the trailer may be used to insert upright elements (100), after removing the corner posts (9), to allow the stacking of several trailers.
