description

The invention relates to a divisible hinge for attaching a side wall to the frame of trucks, consisting

from one part with a horizontal Sj attached on one side

Axle (axle part) and from a corresponding bearing /

Bore having part (bearing part) and from a Aus |

hang securing. £

Divisible hinges of this type are often used for side walls of truck eyes. They allow if necessary; to completely remove a drop side from a truck. This is done by the fact that after folding down the side wall this is moved in a direction parallel to the axis of the hinge •. The safety catch can be different Be kind. A known safety catch consists of a split pin that is inserted into a hole in the part of the axle that is above the bearing bore protrudes, is inserted.

The disadvantage of such unhooking devices is that they first have to be laboriously removed by hand before they can be unhooked the drop side is possible.

The invention was based on the object of providing a divisible hinge of the type described at the beginning with a simple but effective * to provide unhooking protection that allows effortless unhooking of the drop side if necessary, but which is still in prevents the drop side from being unintentionally unhooked every time it is folded down.

This object is achieved according to the invention in that in such a divisible hinge the anti-unhooking device consists of an approach that is projected from the bearing bore

jumping free end of the axis protrudes at right angles, and that the bearing bore has the shape of an elongated hole in its cross-section 5 cross-section through the axis and the approach only with a certain mutual orientation fits, the orientations of the approach and the elongated hole extending in such a way that the elongated hole with the same orientation can only be pushed over the approach if the side wall has been raised against gravity.

Due to the inventive design of the anti-unhooking device, the side wall cannot be unintentionally in any folded-down position falling off. The approach only goes through the elongated hole in a certain folded-down position, and only then after the drop side has been raised.

In a preferred embodiment, the approach corresponds to in terms of its width, the diameter of the axis, and it also at its free end with a radius of the Axis is rounded off accordingly. This training of the approach ensures that the ship's side is only in one whole certain fold-down position can be unhooked.

In a preferred embodiment, the axle part is attached to the vehicle frame and the bearing part is attached to the drop side, wherein the elongated hole extends in the raised position in the horizontal direction and wherein the approach upwards shows. As long as it only points upwards, the approach can adopt different orientations with respect to the horizontal. One possibility is straight up. In this In this case, to unhook the side wall, it must be folded down by 90 ° and then raised, whereupon the bearing bore of the bearing part can be pushed over the approach on the axis of the axle part. Another option is with an angle of 45 ° to the horizontal, obliquely upwards away from the vehicle frame. With such a training, the side wall has to

135 can be folded down and then raised so that the drop side can be unhooked.

In this embodiment, it is also preferred that on Bearing part a projection is provided which rests on the vehicle frame when the side wall is folded up and which the vehicle frame facing end of the elongated hole in the vicinity of the axis holds and preferably even presses against the axis. Through this a sliding back and forth of the bearing part on the axle and the associated noise development is reliably prevented, In this case, it is advantageous if there is a ramp surface on the projection so that when the drop side is folded up, the the end of the elongated hole facing the vehicle is gradually pushed against the axle.

In another embodiment, the bearing part is on the frame and to attach the axle part to the ship's side, whereby the Langioch extends in the vertical direction and the approach to the side or at an angle when the ship's side is folded up at an angle of 45 ° to the horizontal from the vehicle frame facing upwards. Depending on the orientation of the approach, the Unhook the side wall, fold it down at an angle of 90 or 135 ° and then lift it up before the approach through the elongated hole fits through and the side wall can be unhooked.

In this embodiment it is further preferred that lugs are provided on the bearing part, which are provided in the flange of the axle part when the drop side is in the upright position Cover the holes that are used to screw the axle part to the ship's side. These noses serve as customs security. she prevent the folded up drop side, which is part of a

The vehicle body is secured by a customs seal, from The hinge can be unscrewed in order to get to the transported goods without damaging the customs seal. It is there also advantageous if a pin is provided on the axle part which, when the drop side is folded up, is immediately below a the nose lies. The pin prevents the axis from extending in the vertical direction when the ship's side is folded up Long hole and thus the entire drop side can be raised.

Two embodiments of the divisible hinge according to the invention will now be explained in more detail with reference to the accompanying drawings.

Fig. 1 shows an embodiment with half-folded drop side, the axle part on the frame and the bearing part is attached to the drop side and the drop side can only be unhooked in a position folded down by 90 ° is possible.

Fig. 2 shows an embodiment with the side wall folded up, whereby the bearing part is attached to the frame and the axle part is attached to the side wall and only n = ach can be unhooked The drop side can be folded down by 135 °.

1 shows a section of a vehicle frame 1 and a side wall 2 in a schematic representation. On the vehicle frame 1 an axle part 3 is attached, which essentially consists of an axle assembly 5 and a horizontal axle attached to it consists. The axle holder 5 is usually welded to the vehicle frame 1. The axle 6 carries at its free end an upwardly facing approach 7 with a rounding 8, whose The radius of curvature corresponds to that of the axis 6. A bearing part 4 is attached to the side wall 2. The bearing part 4 has a flange 9, which is usually made with the help of screws,

passing through holes (not shown) provided in the flange 9. The bearing part 4 has a Bearing bore IO in the form of an elongated hole with horizontal orientation, which is dimensioned so that the side wall in the half-folded position after lifting over the shoulder 7 on the axle can be pushed so that the drop side can only be unhooked in this position. On the in flipped up On the side facing the vehicle frame 1, the axle part 4 has a projection 11 r. With a run-on surface 12. The projection 11 comes into contact with the vehicle frame 1 when the drop side is folded up, thereby pressing the bearing part 4 towards it Side that the vehicle frame facing end of the elongated hole 10 comes into contact with the axis 6, which prevents the bearing bore 10 slides back and forth on the axle and noise is generated when driving.

Fig. 2 also shows the vehicle frame 1 and the side wall 2, here in the folded-up position. An axle part 13 is welded to the vehicle frame 1. It has an axle holder 15 and a horizontal axle 16 attached to it. The axle holder 15 is in turn attached to a flange 19 which has holes 21 with the aid of which the flange can be screwed to the lower end face of the drop side 2. At its free end, the axis 16 carries a projection 17, which points obliquely upward at an angle of 45 °, with a rounded portion 18, the radius of curvature of which corresponds to that of the axis 16. A bearing part 14 is welded to the vehicle frame 1. It has a bearing bore 20 in the form of a vertically oriented elongated hole. The elongated hole is dimensioned so that it can be pushed in a position folded down by 135 ° over the projection 17 on the axis 16 in order to unhook the side wall. Furthermore, customs security noses 22, 23 are provided on the bearing part, which cover the underside of the holes 21, so that when the side wall is folded up and sealed in this position

the latter cannot be unscrewed from the axle part.

A pin 24 provided on the axle holder 15 of the axle part 13 lies with little play when the side wall is folded up under the customs security lug 23 and prevents the axle part 13 from being raised with respect to the bearing part 14 in this position can be, which yes in the absence of the pin 24 due to the elongated hole extending in the vertical direction 20 would be possible.
