Definitions

• the present invention relates to the trailer support legs defined in the introductory section of the patent claim 1.
• the problem with the known trailers is that the conditions in which the load is shifted to the support of the trailer are not sufficiently taken into account, and the same applies particularly to the re ⁇ quirements for the supporting legs. It is pointed out that for instance while loading a seafreight container which is remarkably heavier than the trailer itself, it is advantageous to leave the trailer brakes in neutral gear, and to allow - at least at the beginning of the shifting process - the trailer to move in under the load. Thus it is advantageous that the trailer is free to move on the ground, for instance supported by the wheels or rollers provided at the rear end of the trai- ler.
• each leg member is fastened, at its articulation point, at such a distance from the rear end of the trailer which roughly corresponds to the total length of the leg member, in which case the free end of the leg member, together with the wheel assembly, is in the high position located in the immediate vicini- ty of the rear end of the trailer.
• each leg member is arranged in the bevelled part of the rear end of the trailer.
• the turning device of the legs particularly a pressure fluid cylinder, is located in the trailer, on the opposite side of the articulation point with respect to the leg member.
• the second articulation point of the pressure fluid cylinder which point is connected to the supporting legs, is located at a distance from the articulation point of the leg members and above it while the leg members are in the high position.
• each leg member is in the high position arranged to be supported against the trailer.
• the rear end of the trailer is provided with supporting members, against which each leg member is arranged to rest in the high position.
• each free end of the leg member there is turnably attached a bogie.
• the wheels of the bogie are at least partly lo ⁇ cated outside the bottom of the trailer chassis while the leg members are in the high position.
• Another advantage of the invention is that any sinking to the ground of the wheels, provided in the support legs, during the loading can be compensated by raising the rear end of the trailer, supported by the legs, gradually as the loading proceeds, and if neces ⁇ sary, one leg can be raised more than the other.
• Another advantage of the invention is that the supporting legs of the trailer fit in a limited, rela ⁇ tively small space.
• Another advantage of the invention is that the power units, such as pressure fluid cylinders, are located in connection with the supporting legs so that there is created a large torque at the beginning of the lifting motion of the trailer, while raising the trailer and the load thereon.
• Yet another advantage of the invention is that in structure the pressure fluid cylinders of the trailer are ordinary, easily available and economical in price. Moreover, due to the invention the pressure fluid cylinders connected to the supporting legs are protected by the chassis of the trailer, so that they are not susceptible to damage. Furthermore, due to the invention the rear end of the trailer is formed as a compact and simple unit. Moreover, the invention enables the shifting of the trailer by means of the bogies both in the high and low positions of the supporting legs.
• figure 1 illustrates a vehicle-trailer combina ⁇ tion, where the trailer legs conform to that of the present invention
• figure 2 illustrates the vehicle-trailer com- bination of figure 1, at the loading stage
• figure 3 illustrates the rear end of the trai ⁇ ler, seen from the side and provided with the legs of the invention
• figure 4 respectively illustrates the rear end of the trailer, seen from the top and reduced in scale as compared to figure 3.
• Figure 1 illustrates a semi-trailer 1 connected to a vehicle, i.e. a tractor 11.
• the said trailer 1 conforms to the present invention and comprises a bogie 2, which in this case includes three axis assemblies; a device 14 for shifting the bogie 2 from the first end, or the rear end la of the trailer 1 to the second end, i.e.
• the supporting legs 3 of the trailer include two elongate leg members 31, 32.
• the turning device comprises two hydraulic cylinders 4, 5, one for each leg member 31, 32.
• Each leg member 31, 32 is fitted and fastened to the side of the trailer 1, behind the rearmost wheels 2a of the bogie 2.
• Each leg member 31, 32 is either separately or simultaneously turnable with respect to its articulation point 6, such as the fasten ⁇ ing axis 6a (figure 4) from the high position A in the vicinity of the trailer chassis to the low position B against the ground or other underlaying surface (marked with dotted lines in figure 3) in order to lift the trailer to the support of the legs.
• the supporting legs 3 are turnable in the opposite direction when it is desired to move the trailer 1 from the support of the legs 3 to the support of the bogie 2.
• the hydraulic cylinders 4, 5 are fastened, when seen from the side, to each leg member 31, 32 at the point 7, and to the chassis of the trailer 1 at the point 10.
• the hydraulic cylinders 4, 5 are turnably fastened at the articulation point 7, by means of the turning axes 7a, 7b, to the leg members 31, 32.
• the articulation point 7 of the hydraulic cylinders 4, 5 and the leg members 31, 32, and respectively the ar ⁇ ticulation point 6 of the leg members 31, 32 and the chassis of the trailer 1, are in figure 3 arranged at a distance a from each other wheen seen from the side of the trailer.
• the line D-D passing via the articulation points 6, 7 is at least roughly vertical to the main longitudinal axis of the leg members, which axis in figure 3 is in the high position A of the leg members parallel to the longitudinal axis C-C of the trailer.
• each leg member there is fastened a bogie 9.
• the bogie 9 is turnably fastened to the leg member so that at least in the turning direction A-B of the leg member 31, 32 the bogie is free to move and thus to be supported against the ground at the various position angles ⁇ of the leg member 31, 32.
