DESCRIPTION:
BRIEF SUMMARY
This invention relates to a rear underride protection for vehicles, especially trucks, comprising a fixed bar transversal to the direction of motion of the vehicle and means for securing the fixed bar relative to the vehicle.
Vehicles having a backwards projecting loading surface or the like are normally provided with a so-called rear underride protection primarily to reduce the risk of severe injuries resulting from accidents at collisions from behind. Moreover, such vehicles as carry a lateral plough in connection with snow clearing are also provided with a so-called sliding bar which is normally connected with a rear attachment of the lateral plough. The sliding bar is further usually detachably connected to the vehicle at the latter's connection means for a trailer. The sliding bar enables a stepless adjustment of desired ploughing width. This is achieved in that the length of the sliding bar is variable, simultaneously as the lateral plough is articulatedly connected to the vehicle at its front portion.
The sliding bar described above has i.a. the following shortcomings. In order to have access to the drawing means of the vehicle and thus to have a possibility of connecting a trailer to the vehicle the sliding bar must be disconnected from the current vehicle between different ploughing occasions. Accordingly the sliding bar must be mounted onto the vehicle at each turn-out which is both time-consuming and toilsome. Another disadvantage is that the blocking of the sliding bar of the drawing means of the vehicle makes a simultaneous connection of a trailer to the vehicle impossible, resulting in that e.g. trailers for spreading salt or sand cannot be connected to the drawing means of the vehicle to be brought along in ploughing.
It is the object of this invention to provide a rear underride protection with a built-in sliding bar not having said disadvantages, and this object is achieved by the device having the characteristic features defined in the claims.
One advantage of the invention in comparison with previously known solutions is that the rear underride bumper and side-draft support of the invention, which is permanently mounted on the vehicle, continuously offers an attachment e.g. for an implement in the form of a lateral plough, simultaneously as the drawing means of the vehicle will not be blocked, as described above. That is to say, the rear underride protection of the invention also comprises a continuously available sliding bar which is very suitable to use in combination with a later described intermediate strut in order to obtain e.g. different angles of incidence of a lateral plough.
Illustrative examples of the invention will be described more in detail in the following with reference to the enclosed drawings, in which
FIG. 1 is a view from behind of a vehicle on which a rear underride bumper and side-draft support according to the invention is mounted,
FIG. 2 shows on a larger scale and partly in section the device of the invention in a state detached from the vehicle inclusive of the intermediate portion,
FIG. 3 shows on a larger schale a section along the line III--III in FIG. 2, and
FIG. 4 shows on a larger scale a section along the line IV--IV in FIG. 2.
FIG. 1 shows a rear underride bumper and side-draft support 1 according to the invention which is mounted at the rear end of a vehicle in the form of a truck 2, which is provided with a lateral plough 3. The lateral plough 3 is in front articulatedly connected to the truck 2 and at the back connected to the rear underride bumper and side-draft support 1 via an intermediate portion 4.
The rear underride bumper and side-draft support 1 comprises a fixed bar 10 and two attachments 11, 12 connected to this so that the fixed bar 10 can be adapted to the frame of the vehicle 2 e.g. by means of screws. The rear underride protection 1 further comprises a movable bar 13 displaceably arranged in the longitudinal direction of the fixed bar 10, which bar 13 at one of its two ends has a means of attachment 14 which in the example shown articul
