[0064] FIG. 9: A second end of the movable lane delimitation element with an articulation device.
[0065] FIG. 1 shows a lane delimitation arrangement 1 with a first stationary lane delimitation element 2, a second stationary lane delimitation element 3 and a movable lane delimitation element 4. The lane delimitation arrangement 1 is in the second position. The first stationary lane delimitation element 2 and the second stationary lane delimitation element 3 are fixedly mounted and the movable lane delimitation element 4 is retractable about a vertical axis between the two stationary lane delimitation elements 2, 3. Furthermore, the movable lane delimiting element 4 is provided to be raised and lowered. For this purpose, the movable lane delimitation element 4 has a lifting device (not shown) and a travelling device (not shown). Lifting and travelling devices can be combined in one device. The lifting device enables a movement in vertical direction and the travelling device enables a pivoting movement along an arc in horizontal direction. The movable lane delimitation element 4 has a first end 12 and a second end 13, wherein a locking element 5 is arranged at the first end 12. The movable lane delimitation element 4 can be retracted from the second position shown to the second stationary lane delimitation element 3 into the third position, whereby different lanes can be passed by traffic in the second and third positions. The movable lane delimiting element 4 has a length of approx. 69 m. The two stationary lane delimitation elements 2, 3 are approx. 12 m long. The two stationary lane delimitation elements 2, 3 have longitudinal axes which run essentially parallel. The lane delimitation elements are made of metal. They are essentially hollow profiles which have good buckling stability.
[0066] FIG. 2 schematically shows the lane delimitation arrangement 1 in the first position in plan view. In the first position of the lane delimitation arrangement 1 the movable lane delimitation element is neither connected to the first stationary lane delimitation element 2 nor to the second stationary lane delimitation element 3. This is therefore an intermediate position which occurs in practical use when the lane delimitation arrangement is swivelled from the second to the third position or when the lane delimitation arrangement is swivelled from the third to the second position.
[0067] FIG. 3 schematically shows the lane delimitation arrangement 1 in the second position in plan view. In the second position of the lane delimitation arrangement 1 the movable lane delimitation element 4 is connected to the first stationary lane delimitation element 2, whereby the movement from the first to the second position of the lane delimitation arrangement 1 is a pivoting movement.
[0068] FIG. 4 schematically shows the lane delimitation arrangement 1 in the third position in plan view. In the third position the movable lane delimitation element 4 is connected to the second stationary lane delimitation element 3, the movement from the first to the third position and the movement from the second to the third position being a pivoting movement.
[0069] FIG. 5 shows an enlarged view of a part of the lane delimitation arrangement 1 of FIG. 1. The movable lane delimitation element 4 has a locking element 5 which engages with the locking arrangement 14 of the first stationary lane delimitation element 2. The locking arrangement 14 and the locking element 5 are therefore in the second position, in which the movable lane delimiting element 4 is connected to the locking arrangement 14 by the locking element 5. The locking element 5 is partially located in the lateral recess 6 of the first stationary lane delimitation element 2 and is attached to the stop device 7 of the first stationary lane delimitation element 2. The locking element 5 is pivoted into the lateral recess 6 of the first stationary lane delimitation element 2 so that no components protrude abruptly into the lane. A monitoring device 8 is provided, by means of which it can be determined by at least one sensor whether the movable lane delimitation element 4 is in the second position. The locking element 5 is lowered onto a pin 9 in the second position. In the second position, the pin 9 is thus partially located in an opening 10 (see FIGS. 6 and 7) of the locking element 5. The first stationary lane delimitation element 2 and the movable lane delimitation element 4 have longitudinal axes which, in the second position, have an angle of substantially 2? relative to one another, while the longitudinal axes of the first stationary lane delimitation element 2 and of the second stationary lane delimitation element 3 are substantially parallel in the third position. In the case of the stop device 7, the lateral recess 6 has a height ha of approx. 31 cm, into which the locking element 5, which has a height hv of approx. 19 cm, is pivoted. The pin 9 has a height hz of approx. 6 cm. The sum of the height of the pin 9 and the height of the locking element 5 is less than the height of the recess 6. The locking element 5 of the movable lane marking element 4 can thus be swivelled into the lateral recess 6 and lowered onto the pin 9.
[0070] FIG. 6 shows the locking element 5 in engagement with a locking device 11 of the second stationary lane delimiting element 3 in the third position analogous to FIG. 4. The locking element 5 has a receptacle for a monitoring device 8 as well as the opening 10. The locking device 11 has a pin 9 which engages in the opening 10. The lateral recess 6 has a height ha of approx. 31 cm in the stop device, into which the locking element, which has a height hv of approx. 19 cm, swivels. The pin 9 has a height hz of approx. 5.6 cm. The movable lane demarcation element 4 can thus be retracted into the lateral recess 6 and lowered onto the pin 9. Within the hollow body of the locking element 5, a recess is provided for a monitoring device 8, by means of which it can be determined whether the pin 9 projects out of the opening 10 into the locking element 5 and thus whether the locking element 5 is fully swivelled into one of the stationary lane delimitation elements 2, 3 and lowered onto the pin 9. This is done, for example, by means of an optical sensor which can determine whether the pin 9 or free air space is located in the opening 10 or in the closure element 5. In this way it can be reliably determined whether the lane marking arrangement 1 is in the second or third position.
[0071] FIG. 7 shows the lane delimitation arrangement 1 in the third position. The locking element 5 is pivoted into the lateral recess 6 of the locking device 11 of the second stationary lane delimitation element 3. The movable lane delimitation element 4 is thus connected to the second static lane delimitation element 3. Furthermore, a receptacle for the monitoring device 8 is shown, which consists of at least one sensor and by means of which it can be determined whether the lane delimitation arrangement 1 is in the second or third position. This is done, for example, by means of an optical sensor, by means of which it can be determined whether the pin 9 or free air space is located in the opening 10 or in the locking element 5. This makes it possible to reliably determine whether the lane delimitation arrangement 1 is in the second or third position. The pin 9 is located in the opening 10, whereby the pin 9 in the third position projects approx. 5.6 cm into the locking element 5. Thus the locking element 5 cannot be retracted without first being lifted vertically. The locking element 5 can be stopped against the stop device 7 after the swivelling process. The movable lane delimitation element 4 and the second static lane delimitation element 3 each have a longitudinal axis which, in the third position of the lane delimitation arrangement 1 shown, have an angle of approx. 3? relative to each other.
[0072] FIG. 8 shows a side view of the locking arrangement 14 from FIG. 1 of the first stationary lane delimitation element 2. The locking element 5 of the movable lane delimitation element 4 can be pivoted into the side recess 6 of the first stationary lane delimitation element 2. The locking element 5 can be lowered onto the pin 9. The stop device 7 serves to position the closure element 5 of the movable lane delimitation element 4 precisely before it is lowered onto the pin 9. The closure arrangement 14 has connecting means 16 with which the closure arrangement can be connected to other lane delimitation elements. The overall height of the locking arrangement h.sub.va is approx. 55 cm and the length of the recess L.sub.a is approx. 4.48 m.
[0073] FIG. 9 shows the second end 13 of the movable lane delimitation element 4 of FIG. 1 with an articulation device 15. The articulation device allows the movable lane delimitation element to pivot about a substantially vertical axis.
