BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a foot for a routing device for road traffic, in which a traffic beacon is detachably coupled to the foot. Such traffic beacons are used particularly at building sites, at which the flow of traffic is to be changed, in order to mark the altered traffic streams. In particular, this occurs where traffic streams flowing in opposite directions are to be partitioned from one another without separation by broad strips of roadway. The traffic beacons are either coupled individually to their own foot or fastened to a base plate composed of individual sections. The traffic beacons are constructed so that they cannot be damaged by the unintentional, but not always avoidable, collision with a vehicle. This can be achieved owing to the fact that it is possible to bend over and even drive over the traffic beacons. The traffic beacons then straighten up once again because of their inherent elasticity.
A known device of the above type is described, for example, in the German utility patent DE 29 503 161. For this device, the traffic beacon is coupled to the foot by a the flange, disposed at the lower edge of the traffic beacon, which can be pushed sideways into appropriately shaped recesses in the foot. In the pushed-in position, the traffic beacons are held only by positive locking between mutually engaging parts. As a consequence, the parts can become detached from one another in operation, that is, for instance, by collision with vehicles. This is undesirable even when the traffic beacon moves only a short distance and not completely out of the recess in the foot.
It is therefore an object of the invention to provide secure fastening of the traffic beacon in the foot.
SUMMARY OF THE INVENTION
This objective is accomplished by providing a foot which includes a foot plate and clamping jaws mounted thereto. The clamping jaws include cross members having nubs which press into a flange of a traffic beacon received in a space between the cross members and the foot plate when the cross members are urged towards the foot plate.
Owing to the fact that the nubs at the clamping jaws always press into the material of the flange, disposed at the lower end of the traffic beacon, any unintentional loosening of the connection between the traffic beacon and the foot is avoided.
Further advantageous developments of the foot are also provided.
In the following, the invention is explained by means of an example shown in the drawing, in which like reference numerals designate the same elements.

DETAILED DESCRIPTION OF THE INVENTION
The foot consists of a foot plate 1, which is intended to lie on the substrate, and of clamping jaws 2, which are detachably connected with the foot plate 1. The foot plate 1 and the clamping jaws 2 are connected by means of screws 5, which are inserted through screw holes in the clamping jaws 2. At the underside of the foot plate 1, there are depressions for accommodating nuts 6. The shape of the depressions corresponds to that of the nuts 6, so that the latter are prevented from rotating. The depth of the depressions is such that the nuts 6 do not protrude below the underside of the foot plate 1.
Each clamping jaw 2 has an inwardly directed cross member 3, the distance of which from the upper side of the foot plate 1 corresponds to the height of the flange of the traffic beacon. At the underside of each cross member 3, there are nubs 4, which are pressed into the soft elastic material of the flange when the screws 5 are tightened, so as to ensure that the traffic beacon is fastened securely in the foot.
Between the cross members 3, but at a distance from these, there is an elevation 7, which is fastened to the foot plate 1 and has an essentially rectangular shape in plan view as well as in side view. The dimensions of the elevation 7 in the longitudinal direction are selected so that the elevation 7, with positive connection, engages the traf
