13. The roadblock according to claim 1, characterized in that the roadblock is provided with at least one friction-increasing element attached to the upper wall of the elongated casing such that at least one contact edge of the friction-increasing element is protruding from a longitudinal side wall of the elongated casing.

14. A roadblock for temporary installation to block traffic and/or as a security precaution, comprising: an elongated casing with two opposing longitudinal side walls, the two side walls joining an upper wall; at least one casing support structure located in the elongate casing; supports for resting on the ground/surface connected to the lower side of the elongate casing and/or the lower side of the casing support structure; and plural stabilization arms protruding from one of the longitudinal side walls, each of which stabilization arms includes a telescopic sliding inner arm segment movable out of a larger outer arm segment; wherein the protruding length of each of the stabilization arms is adjustable by telescopically sliding a respective inner arm segment out of a respective larger outer arm segment.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention will be further elucidated on the basis of the non-limitative exemplary embodiments shown in the following figures, herein shows:

(2) FIG. 1 a perspective view of a roadblock according the present invention with limited length of the stabilisation arms;

(3) FIG. 2 a perspective frontal view of the roadblock shown in FIG. 1 with longer stabilisation arms than the state shown in FIG. 1;

(4) FIG. 3A a side view of the roadblock in the state shown in FIG. 1;

(5) FIG. 3B a side view of the roadblock in the state shown in FIG. 2; and

(6) FIG. 4 a cut-away side view of a part of the roadblock shown in the previous figure showing a part of the interior.

DESCRIPTION OF THE INVENTION

(7) FIG. 1 shows a roadblock 1 with an elongate casing 2 with a longitudinal side wall 3, an upper wall 4 and a chamfered end part 5 with couplings 6. A casing support structure is located in the elongate casing 2. On the lower side of the roadblock 1 supports 8 are attached for resting on the ground/surface and four stabilisation arms 9 protrude from the longitudinal side wall 3. On the upper wall 4 are friction-increasing elements 10 attached with fixing bolts 11. In the state represented in this FIG. 1 the stabilisation arms 9 are collapsed and have only a limited length enabling a relative simple handling, transportation and storage of the roadblock 1.

(8) FIG. 2 shows the roadblock 1 shown in FIG. 1 with longer stabilisation arms 9 than the state shown in FIG. 1. Here the stabilisation arms 9 are extended; telescopic sliding inner arm segments 12 are moved out of larger outer arm segments 13. The extended position of the inner arm parts 12 is secured by locking pins 14.

(9) FIG. 3A a side view of the roadblock 1 in the state shown in FIG. 1, thus with collapsed stabilisation arms 9. Also visible is that the locking pin 14 secures the “stowed away” inner arm segment 12 in the outer arm segment 13. In this figure also a better view is provided on a support 8. The support 8 has a sharp angled central protrusion 15 facing downward and the protrusion 15 is located on the side of a (fictional) vertical central plane 16 though the roadblock 1 opposite the side of the roadblock 1 with the stabilisation arms 9. The support 8 further also has a second sideward protrusion 17 also facing down and this second sideward protrusion 17 is located alongside the elongated casing 2 on the side facing away from the stabilisation arms 9. The second sideward protrusion 17 has three sharp angles 18. Also clearly visible is that the central protrusion 15 protrudes further down than the sideward protrusion 17. In FIG. 3B the side view of the roadblock 1 according FIG. 3A is shown again but here, like in FIG. 2, the inner arm segment 12 is moved out of larger outer arm segment 13 thus the stabilisation arm 9 is now in a longer state. The angle α enclosed by the stabilisation arm 9 and the vertical central plane 16 (or the longitudinal side wall 3) is more than 90°.

(10) FIG. 4 shows a cut-away part of the roadblock 1 with a part of the interior of the roadblock. A part of a casing support structure 19, which is located in the elongate casing 2, holds a wheel 20 of which the position is adjustable so that the wheel 20 may be lowered so far that it protrudes to below the lower side 21 of the roadblock 1. For adjustment of the position of the wheel 20 a bolt coupling 22 is accessible through the upper wall 4.
