Roadblock for Temporary Installation to Block Traffic and/or as a Security Precaution

Abstract

A roadblock for temporary installation to block traffic and/or as a security precaution includes an elongated casing with two opposing longitudinal side walls. The two side walls join an upper wall. At least one casing support structure is located in the elongated casing and connects to both side walls. Supports for resting on the ground/surface are connected to the lower side of the elongated casing and/or the lower side of the casing support structure. Plural stabilization arms protrude from one of the longitudinal side walls and are detachable.

DESCRIPTION OF THE INVENTION

[0026] FIG. 1 shows a roadblock 1 with an elongated casing 2 with a longitudinal side wall 3, an upper wall 4 and a chamfered end part 5 with couplings 6. On the lower side of the roadblock 1, supports 8 are attached for resting on the ground/surface and four stabilization 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 FIG. 1, the stabilization arms 9 are collapsed and have only a limited length enabling a relatively simple handling, transportation, and storage of the roadblock 1.

[0027] FIG. 2 shows the roadblock 1 shown in FIG. 1 with longer stabilization arms 9 than in the state shown in FIG. 1. As shown in FIG. 2, the stabilization arms 9 are extended and 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.

[0028] FIG. 3A is a side view of the roadblock 1 in the state shown in FIG. 1, thus with collapsed stabilization arms 9. Also visible is a locking pin 14 that 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. Support 8 has a sharp angled central protrusion 15 facing downward and the protrusion 15 is located on the side of a (frictional) vertical central plane 16 extending through the roadblock 1 opposite the side of the roadblock 1 with the stabilization arms 9. 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 stabilization 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 roadblock 1 is shown but here, like in FIG. 2, inner arm segment 12 is moved out of larger outer arm segment 13, thus stabilization arm 9 is now in a longer state. An angle enclosed by the stabilization arm 9 and the vertical central plane 16 (or the longitudinal side wall 3) is more than 90.

[0029] FIG. 4 shows a cut-away part of roadblock 1 with a part of the interior of the roadblock. A part of a casing support structure 19, which is located in the elongated casing 2, holds a wheel 20 of which the position is adjustable so that wheel 20 may be lowered so far that it protrudes below a lower side 21 of roadblock 1. For adjustment of the position of wheel 20, a bolt coupling 22 is accessible through upper wall 4. As shown most clearly in FIGS. 1 and 2, casing support structure 19 also includes parts 7 protruding from the side wall 3.
