DETAILED DESCRIPTION OF THE INVENTION 'In Fig. 1, a stop device is mounted on a floor of a cabinet vehicle under floor 10. The stopping device is in the locking position where it holds the side door 11 of the cabinet-35 vehicle open so that the retracting force of the film-like hinge 12 of the full height of the door 11 is not able to swing the door. The stopping device comprises a plate-like body 2 attached to the floor 11, for example by welding, bolts or glue, with a pivotable plate-like arm part 1. The body-part 2 and the arm part 1 are easily made by stamping 5 on a steel plate. The arm portion 1 is pivotally mounted to the body member 2 by a pin-like pivoting member 5, preferably a bolt. In Figure 1, the inner surface 11 of the door rests freely on the support member 4 at the end of the stop member arm member 1; In the position of Fig. 1, the stem member 1 cannot pivot so that the angle α pie-10 could be increased and the door 11 could be closed due to the stopping device comprising a wedge-shaped stop member 3 against which the stop surface 6 of the arm member 1 rests.

In Fig. 2, the stopping device is in the stowed position (i.e., the "driving position"). In this case, the arm portion 1 is at another angle β, about -90 ° with respect to the body portion. Figures 3 to 5 illustrate how the stopping device could be moved from the closing position of Figure 1 to the holding position of Figure 2.

Figures 3 to 5 show the stop device of Fig. 1 with the difference that the stop device of Figs. 3-5 is intended to hold open the swing doors, whereas the stop device of Fig. 1 is designed to keep the right swing doors open. . The only structural difference in the stopping devices of Figures 1 and 3 is that the response portions 3 and 4 respectively. 3 'is secured, typically welded, at various points on the body members 2: 2'.

· ·

In order to obtain the stopping device from the locking position of Fig. 1 to the retaining position (i.e., "driving position") of Fig. 2, the arm part 1 must be depressed, cf.

5 · arrow A in Fig. 5, and further rotates the shaft portion. The articulation means 5 'comprises a pin v: 50' surrounded by a helical spring 5T which at one end is adapted to rest on the body portion 2 'and is supported at its opposite end by a nut 52' formed at the end of the pin or other am-30 skilled in the art. future support. The spring 51 'holds the arm 1' Λ nor-mally the body portion 2 'against, but allows the pivot arm of the V away from the body when the pressure in the arrow A direction. When the arm 1 ''; · * further rotated in the direction of arrow B, the arm portion a stop part 3 'under and over, see. Figure 3.

·: ··· 35 The body 2 'has an opening 20' larger than the diameter of the bolt 5 '(pin 50'), which allows the bolt and arm 5 to be inclined 5109983 with respect to the body 2 'when the arm is pressed the arrow A direction. Preferably, the head 53 'of the bolt 5' may rest freely against the arm portion 1 ', i.e. the bolt 5' need not be fixed, e.g. by welding, to the arm portion.

The support portion 4 'at the end of the arm portion 1' is fixed to the bore 30 'formed in the arm portion, cf. Fig. 5. Alternatively, the support member 4 'may be secured to an additional bore 3T, depending on the application of the stop device.

Fig. 5 shows that the stop device is arranged in a notched space 100 formed in the vehicle floor 10. The size of the space 100 disposed between the floor 10 10 and the door 11 is such that the bolt 5 'or other articulation . Due to the notched space 100, the stopping device is out of the way and at the same time protected from possible mechanical shocks. The structure of the stop device allows the bolt to be rotated with respect to the frame 2 'so that the bolt head 53' points towards the lower surface 15 of the floor 10 and the pin 50 'with springs 51' and nuts 52 'points away from the frame 2' and the lower surface. Such a solution does not require a notched space 100 (grooves) at the edge of the floor 10, but the pin 50 'with springs 51' and nuts 52 'may in some applications be on the road and thus also vulnerable to external shocks.

When the stopping device is in the storage position, the planes defined by the arm T and the body 2 'are parallel, and the arm 1' rests against the body 2 'via a large circular bearing surface, cf. Figures 4 and 7.

; *. Figures 6 and 7 show that the arm portion 1 is shaped like a clock of a clock, having two stop surfaces 6, 6 'which are symmetrical in relation to its longitudinal direction, which facilitates the assembly of the stop device.

The invention has been described above by way of one example only, and it is therefore noted that the invention is practicable in detail within the scope of the appended claims. Thus, for example, the design of the stop device and the point of attachment to the vehicle may vary. The vehicle * · · does not have to be a closed box body, but may be another type of truck, for example, with only partially enclosed regular space. It is conceivable that, instead of the floor, the stop device may be attached to the lower end of the vertical · · · · ·: 35 body of the truck, where it can be positioned due to its small size. Alternatively, another joint may be used instead of the bolt.

However, the bolt as a joint means is structurally simple and inexpensive. However, the stopping device according to the figure is very advantageous in design because the large bearing surface of the device makes the device very durable. The response part need not be wedge-shaped. The stopping device is illustrated in the example for use with only one door (door leaf), and it is noted that the invention is particularly well suited for use in preventing vehicle door packages, i.e. multiple doors (door leaves) secured to a vehicle by a common hinge.
