LANE DELIMITATION ARRANGEMENT AND METHOD FOR DELIVERING VEHICLES

Description

[0001] The present invention relates to a lane marking arrangement and a method for diverting vehicles.

[0002] Lane markings are passive restraint systems on roads. Their primary purpose is to prevent vehicles from straying from a lane. This protects areas outside the lane from impact, while also preventing more serious impacts on the vehicle and its occupants from falling down slopes or colliding with, for example, oncoming traffic or trees. Furthermore, the potential consequences of an accident are reduced by absorbing the vehicle's kinetic energy through deformation or displacement of the lane marking during an impact.

[0003] For some applications, mobile lane marking elements are necessary. These allow, for example, construction sites to be secured and lanes to be quickly set up, dismantled, or diverted. In times of high traffic volumes, changing lane markings to adjust the lane layout must be done very quickly. To be able to divert traffic flows quickly and efficiently to other lanes, lane marking elements must be implemented quickly and efficiently.

[0004] For example, there are pivoting, semi-mobile systems that can be used to selectively open the traffic lanes on demand and divert traffic to the opposite lanes. These systems do not allow for flexible, on-demand diversion of traffic flow and / or traffic direction while maintaining the guardrail function.

[0005] To meet the above-mentioned requirements, a number of movable and movable guardrail systems are known from the prior art. EP3569765A1 discloses that stationary and movable lane marking elements can be connected to a locking device. The movement of the movable lane marking element and the closing of the locking device take place sequentially. Especially with pivoting lane marking elements, the positioning of the locking device must be very precise and can therefore only be carried out slowly.

[0006] WO 2019 / 011424 A1 discloses a closure element of a roadway delimitation device that is rotatable relative to a guide element from a closed position to an impact position. DE 10 2008 016837 A1 discloses a guide device comprising a stationary guide sill and a horizontally pivoting guide sill.

[0007] It is therefore the object of the invention to overcome the disadvantages of the prior art and in particular to provide a lane marking arrangement and a method for diverting vehicles which can be carried out simply and safely and in particular retains the guardrail function.

[0008] The problem is solved by a lane marking arrangement and a method for diverting vehicles according to the independent claims.

[0009] In particular, the object is achieved by a lane delimitation arrangement comprising at least a first stationary lane delimitation element and a movable lane delimitation element that is movable relative to the first stationary lane delimitation element. The movable lane delimitation element comprises a first end and a second end, wherein the second end preferably comprises a joint device and the first end comprises a closure element. The first stationary lane delimitation element has a closure arrangement complementary to the closure element, wherein the movable lane delimitation element has a first position in which the stationary and movable lane delimitation elements are not connected.Furthermore, the movable lane delimiter element has a second position in which the stationary and movable lane delimiter elements are connected to one another, wherein, in the second position, the closure element of the movable lane delimiter element engages the closure arrangement of the first stationary lane delimiter element. The movement of the movable lane delimiter element from the first to the second position is a pivoting movement. The closure element has a lateral recess for the closure arrangement of the first stationary lane delimiter element, or the closure arrangement of the first stationary lane delimiter element has a lateral recess for the closure element.

[0010] Such a lane marking arrangement allows for easy and quick engagement of the movable lane marking element with the stationary lane marking element, and closure is secure and uncomplicated, even after a pivoting movement. Furthermore, the closure is so stable that the required guardrail function is maintained.

[0011] The lane delimitation arrangement may comprise a second stationary lane delimitation element having a closure device complementary to the closure element. The movable lane delimitation element may, in particular, have a third position in which the second stationary lane delimitation element and the movable lane delimitation element are connected.

[0012] Preferably, the two stationary lane delimitation elements each have a longitudinal axis which are arranged substantially parallel to one another.

[0013] In particular, the closure element is designed such that it can engage with the closure device and the closure arrangement.

[0014] This allows vehicles to be easily and efficiently directed to a first or second lane. Since the closure arrangement of the first stationary lane marking element and the closure device of the second stationary lane marking element are each complementary to the closure element, the closure element can be connected to the first and second lane marking elements in the second and third positions, respectively, in a similar manner. This allows the movable lane marking element to be closed quickly and efficiently in the second and third positions. Furthermore, the lane marking arrangement is constructed simply and effectively in this way and can be used immediately as a guardrail in both positions in which the closure is closed.

[0015] The movable lane marking element can be lockable in the locking arrangement and / or the locking device.

[0016] This ensures that the movable lane marking element cannot be accidentally displaced in the second or third position and remains connected to the other lane marking elements even in the event of external influences, e.g., a vehicle impact. The movable lane marking element can be locked in place, yet can still be quickly released. Thus, the locking element is stably and securely connected to the first stationary lane marking element or the second stationary lane marking element, while still being quickly pivotable from the second to the third position. This makes the lane marking arrangement particularly efficient.

[0017] The movable lane delimitation element can be pivoted with its first end completely into the lateral recess of the first or second stationary lane delimitation element.

[0018] In the context of the invention, "fully retractable" means that the first end of the movable lane marking element does not protrude into the lane after the closure is closed, but rather forms a substantially flat surface. It is of course possible for the surface to include recesses and openings, but these do not have a significant impact on safety.

[0019] At the same time, such a closure ensures that the roadway barrier element, in any pivoted-in state, meets a tensile strength at the level of the required restraint performance for vehicles according to the current standards.

[0020] This ensures that vehicles can safely pass through the lane markings without colliding with protruding elements. Furthermore, it creates a visually seamless transition between the lane markings for the occupants of passing vehicles, ensuring a pleasant and safe passage.

[0021] The first stationary lane delimitation element can have a longitudinal axis and the lateral recess of the first stationary lane delimitation element can have a stop device as a stop for the movable lane delimitation element, wherein the angle between the longitudinal axis and the stop device is in particular between 1° and 5°, in particular 2°.

[0022] Analogously, the second lane marking element can also have a stop device.

[0023] The locking element hits the stop device when pivoting into the second or third position. This eliminates the need for control elements to bring the locking element to a stop precisely in the second or third position. The pivoting process is therefore very simple, error-free, and fast.

[0024] The movable lane marking element can have a length of more than 60 m from the first to the second end. The first stationary lane marking element and the movable lane marking element have longitudinal axes which, in the second position, form a very acute angle of essentially 3° relative to one another. The resulting uniform surface of the lane marking arrangement without projections ensures that vehicles can pass the lane marking arrangement, which is in the second or third position, at an appropriate speed. The design of the closures of the lane marking arrangement allows a very acute angle between the closure parts and, at the same time, a very space-saving design, so that the lane marking elements can have a width of less than 40 cm, preferably less than 30 cm.The lane marking arrangement is therefore very space-saving and can be used particularly advantageously in locations with limited space, for example, when the number of lanes is reduced due to maintenance work on a road section. Furthermore, due to the acute angle between the longitudinal axes of the first stationary lane marking element and the movable lane marking element, the lane marking arrangement can be used preferably in the area of construction sites or other locations where vehicles must be diverted, without the vehicles having to significantly reduce their speed due to the large curve radii of the lanes. This ensures a pleasant driving experience when passing the lane marking arrangement and also ensures the efficiency of the road on which the lane marking arrangement is installed.

[0025] The lane marking elements can be made of steel, plastic, and / or a composite material. The use of these materials makes the lane marking elements, and thus the lane marking arrangement as a whole, robust, durable, and resistant to external influences (e.g., weathering, freeze-thaw cycles, exposure to de-icing salt and / or brine).

[0026] The closure arrangement and / or the closure device can each have a pin, wherein the closure element has an opening complementary thereto, or the closure element has a pin and the closure arrangement and / or the closure device each have an opening complementary thereto.

[0027] The connection between the movable lane delimitation element and the first stationary lane delimitation element or the second stationary lane delimitation element in the second and / or third position is thus simple, compact and stable.

[0028] In a further variant of the invention, the pin of the closure arrangement and / or the closure device can be designed such that in the second and / or third position it extends through the opening of the closure element and projects into it by at least 4 cm.

[0029] This ensures that the locking element cannot accidentally slip off the pin from the second or third position. The pin's protrusion into the opening also makes it particularly easy for an operator or a monitoring device to visually check whether the lane marking arrangement is in the second or third position.

[0030] The lane marking arrangement can be designed to include a monitoring device, in particular with at least one sensor. The monitoring device is designed to determine whether the movable lane marking element is in the second or third position.

[0031] The monitoring device may comprise an optical, electronic, or acoustic sensor. The monitoring device may, for example, have a laser sensor, an ultrasonic sensor, or a capacitive sensor. The monitoring device may be connected wirelessly or wired to a control unit that evaluates the sensor data.

[0032] This allows the position of the lane marking system and whether the lane marking elements are securely closed to be determined remotely using a wireless or wired connection device, without requiring an operator on-site. Multiple lane marking systems can also be remotely monitored and / or controlled, thus directing traffic. This allows one or more lane marking systems to be combined into a lane marking system or road switch, which can be remotely monitored and thus operated easily and efficiently.

[0033] The monitoring device can be designed in such a way that it can be determined whether the pin of the closure arrangement or of the closure device is located in the opening of the closure element or whether the pin of the closure element is located in the opening of the closure arrangement or of the closure device.

[0034] Monitoring the engagement of the pin in an opening is a simple and safe monitoring method.

[0035] The movable lane marking element may comprise a lifting device and in particular a chassis.

[0036] The chassis and lifting device can be designed as a single travel lifting device or separately. Furthermore, the chassis and lifting device can be designed so that the movable lane marking element can be moved without requiring an operator on site.

[0037] This allows the movable lane marking element to be raised and pivoted quickly and easily. This particularly preferably enables both the pivoting movement of the movable lane marking element and the closing process of the movable lane marking element with the first and / or second stationary lane marking element. Furthermore, the movable lane marking element can be pivoted between positions without the need for an operator on-site. Rather, the movable lane marking element can be moved into the different positions by remote control. This enables particularly efficient control of the lane marking arrangement.

[0038] The object of the invention is further achieved by a road switch which, in particular, comprises at least one lane marking arrangement as described above, wherein a movable lane marking element, a first stationary lane marking element, and a second stationary lane marking element are formed. The road switch has at least a first state and a second state. In the first state, the movable lane marking element is completely pivoted into the first stationary lane marking element and connected thereto. Preferably, in the first state, the movable lane marking element is laterally pivoted into the first stationary lane marking element. In the second state, the movable lane marking element is completely pivoted into the second stationary lane marking element and connected thereto.Preferably, in the second state, the movable lane delimitation element is pivoted laterally into the second stationary lane delimitation element.

[0039] The movable lane delimiter, as well as the first stationary lane delimiter and the second stationary lane delimiter, have longitudinal axes, wherein the longitudinal axes of the first stationary lane delimiter and the second stationary lane delimiter run substantially parallel. In the first state of the road switch, in which the movable lane delimiter is connected to the first stationary lane delimiter, the longitudinal axes of the movable lane delimiter and the first stationary lane delimiter form an acute angle of between 1° and 5°, and preferably 2°.In the second state of the road switch, in which the movable lane marking element is connected to the second stationary lane marking element, the longitudinal axes of the movable lane marking element and the second stationary lane marking element form an acute angle of between 1° and 5°, preferably 2°. Due to the acute angle and the resulting large curve radii, vehicles can safely pass the road switch without having to significantly reduce their speed. This allows the road switch to be used particularly advantageously without becoming a bottleneck on a road. It is therefore extremely unlikely that traffic will slow down or that vehicles will come to a standstill in front of the road switch.

[0040] The road switch can be moved from the first state to the second state or from the second state to the first state by pivoting the movable lane marking element of the road switch on a substantially horizontal plane. Preferably, the first stationary lane marking element and the second lane marking element are each provided with lateral recesses so that the movable lane marking element can be pivoted laterally into the first stationary lane marking element and / or the second lane marking element. Preferably, in the first state and the second state, the movable lane marking element is pivoted into the first or second stationary lane marking element, respectively, so that no parts protrude suddenly into the clearance profile of the lane.This allows vehicles to safely pass through the road switch without the risk of collision due to protruding parts. This makes the road switch safe and pleasant to pass.

[0041] Because the movable lane marking element changes from the first state to the second state by pivoting, and is preferably pivotable into the first stationary lane marking element or the second lane marking element and connectable to the first or the second lane marking element, the road switch can be pivoted easily and quickly from the first state to the second state or from the second state to the first state. This makes the pivoting process simple and efficient.Because the pivoting movement causes the switch to change its state, and simultaneously connects the movable lane marking element to the first stationary lane marking element or the second stationary lane marking element, the switch states change simultaneously, as does the connection of the movable lane marking element to the first stationary lane marking element or the second stationary lane marking element. This allows the switch to be moved quickly and easily from the first state to the second state, or from the second state to the first state. This makes the process quick, simple, and error-free.

[0042] Preferably, a road switch has two lane marking arrangements. This allows vehicles to be directed into different lanes in a particularly advantageous manner.

[0043] The object of the invention is further achieved by a method for diverting vehicles from one lane to another using a lane delimitation arrangement as described above, comprising the following steps: Raising a movable lane delimiter, releasing a closure element of the movable lane delimiter from a closure arrangement or a closure device, pivoting the movable lane delimiter over a lane, lowering a movable lane delimiter.

[0044] This process allows vehicles to be easily and safely diverted from one lane to another. Connecting the movable lane marking element to a locking arrangement or locking device that is easy to release ensures that the movable lane marking element is securely connected to the locking arrangement or locking device, yet can still be quickly released and moved. This results in a particularly efficient process.

[0045] In the method, the lifting of the movable lane marking element can simultaneously lead to the release of the closure element from the closure arrangement.

[0046] This combines two steps of the process - lifting and releasing the lock - which speeds up and simplifies the process as a whole.

[0047] The closure element of the movable lane marking element can pivot into a lateral recess of a stationary lane marking element after pivoting over the lane.

[0048] This allows the movable lane marking element in the second and third position to be quickly and easily connected to the first or second lane marking element.

[0049] The closure element of the movable lane delimitation element can engage the closure arrangement or closure device of a stationary lane delimitation element by lowering the movable lane delimitation element.

[0050] By simultaneously lowering and engaging the closure element into the closure assembly or closure device, two process steps are combined. This makes the process simple and efficient.

[0051] The pivoting and lowering of the movable lane marking element can be done, for example, by means of the lifting device which is mounted under the movable lane marking element.

[0052] The invention is explained in more detail in the following figures. Fig. 1: A lane marking arrangement with two stationary lane marking elements and one movable lane marking element, Fig. 2: Schematic representation of the lane marking arrangement in plan view in the first position, Fig. 3: Schematic representation of the lane marking arrangement in plan view in the second position, Fig. 4: Schematic representation of the lane marking arrangement in plan view in the third position, Fig. 5: Lane marking arrangement with a closure arrangement and a closure element in the second position, Fig. 6: A longitudinal section through a closure element and a closure device in the third position, Fig. 7: A section through a closure element and a closure device, Fig. 8: A side view of a closure arrangement of a first stationary lane marking element, Fig.9: A second end of the movable lane marking element with a joint device.

[0053] Fig. 1shows a lane marking arrangement 1 with a first stationary lane marking element 2, a second stationary lane marking element 3, and a movable lane marking element 4. The lane marking arrangement 1 is in the second position. The first stationary lane marking element 2 and the second stationary lane marking element 3 are fixedly mounted, and the movable lane marking element 4 can be pivoted about a vertical axis between the two stationary lane marking elements 2, 3. Furthermore, the movable lane marking element 4 is designed to be raised and lowered. For this purpose, the movable lane marking element 4 has a lifting device (not shown) and a moving device (not shown). The lifting and moving devices can be combined in one device.The lifting device enables movement in a vertical direction and the traveling device enables a pivoting movement along an arc in a horizontal direction. The movable lane marking element 4 has a first end 12 and a second end 13, with a closure element 5 being arranged at the first end 12. From the illustrated second position, the movable lane marking element 4 can be pivoted to the second stationary lane marking element 3 in the third position, with different lanes being passable for traffic in the second and third positions. The movable lane marking element 4 has a length of approximately 69 m. The two stationary lane marking elements 2, 3 have a length of approximately 12 m. The two stationary lane marking elements 2, 3 have longitudinal axes that run essentially parallel.The lane marking elements are made of metal. They are essentially hollow sections that offer good buckling stability.

[0054] Fig. 2 shows a schematic plan view of the lane marking arrangement 1 in the first position. In the first position of the lane marking arrangement 1, the movable lane marking element is connected neither to the first stationary lane marking element 2 nor to the second stationary lane marking element 3. It is therefore an intermediate position that occurs in practical use when pivoting the lane marking arrangement from the second to the third position or when pivoting the lane marking arrangement from the third to the second position.

[0055] Fig. 3shows a schematic plan view of the lane marking arrangement 1 in the second position. In the second position of the lane marking arrangement 1, the movable lane marking element 4 is connected to the first stationary lane marking element 2, wherein the movement from the first to the second position of the lane marking arrangement 1 is a pivoting movement.

[0056] Fig. 4 shows a schematic plan view of the lane marking arrangement 1 in the third position. In the third position, the movable lane marking element 4 is connected to the second stationary lane marking element 3, with the movement from the first to the third position and the movement from the second to the third position being a pivoting movement.

[0057] Fig. 5 shows part of the lane marking arrangement 1 from Figure 1in an enlargement. The movable lane delimiter 4 has a closure element 5 which engages with the closure arrangement 14 of the first stationary lane delimiter 2. The closure arrangement 14 and the closure element 5 are therefore in the second position, in which the movable lane element 4 is connected to the closure arrangement 14 by the closure element 5. The closure element 5 is partially located in the lateral recess 6 of the first stationary lane delimiter 2 and is attached to the stop device 7 of the first stationary lane delimiter 2. The closure element 5 is pivoted into the lateral recess 6 of the first stationary lane delimiter 2 so that no components protrude suddenly into the lane.A monitoring device 8 is provided, which can be used to determine, by means of at least one sensor, whether the movable lane marking element 4 is in the second position. In the second position, the closure element 5 is lowered onto a pin 9. In the second position, the pin 9 is thus partially located in an opening 10 (see ). Figure 6 and 7) of the closure element 5. The first stationary lane delimitation element 2 and the movable lane delimitation element 4 have longitudinal axes which, in the second position, form an angle of substantially 2° relative to one another, while the longitudinal axes of the first stationary lane delimitation element 2 and the second stationary lane delimitation element 3 run substantially parallel in the third position. The lateral recess 6 in the stop device 7 has a height ha of approximately 31 cm, into which the closure element 5, which has a height hv of approximately 19 cm, is pivoted. The pin 9 has a height hz of approximately 6 cm. The sum of the height of the pin 9 and the height of the closure element 5 is smaller than the height of the recess 6. The closure element 5 of the movable lane delimitation element 4 can thus be pivoted into the lateral recess 6 and lowered onto the pin 9.

[0058] Fig. 6 shows the closure element 5 in engagement with a closure device 11 of the second stationary lane delimitation element 3 in the third position analogous to Figure 4The closure element 5 has a receptacle for a monitoring device 8 and the opening 10. The closure device 11 has a pin 9 which engages in the opening 10. The lateral recess 6 of the stop device has a height ha of approximately 31 cm, into which the closure element, which has a height hv of approximately 19 cm, pivots. The pin 9 has a height hz of approximately 5.6 cm. The movable lane marking element 4 can thus be pivoted into the lateral recess 6 and lowered onto the pin 9. Within the hollow body of the closure element 5, a recess is formed for a monitoring device 8, by means of which it can be determined whether the pin 9 projects from the opening 10 into the closure element 5 and thus whether the closure element 5 is completely pivoted 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. This allows for reliable determination of whether the lane marking arrangement 1 is in the second or third position.

[0059] Fig. 7shows the lane marking arrangement 1 in the third position. The closure element 5 is pivoted into the lateral recess 6 of the closure device 11 of the second stationary lane marking element 3. The movable lane marking element 4 is thus connected to the second stationary lane marking 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 marking 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 closure element 5. This makes it possible to reliably determine whether the lane marking arrangement 1 is in the second or third position.The pin 9 is located in the opening 10, with the pin 9 projecting approximately 5.6 cm into the closure element 5 in the third position. Thus, the closure element 5 cannot be pivoted without first being raised vertically. After pivoting, the closure element 5 can be stopped against the stop device 7. The movable lane marking element 4 and the second stationary lane marking element 3 each have a longitudinal axis, which, in the illustrated third position of the lane marking arrangement 1, form an angle of approximately 3° relative to one another.

[0060] Fig. 8 shows a side view of the closure assembly 14 from Figure 1of the first stationary lane delimiter 2. The closure element 5 of the movable lane delimiter 4 can be pivoted into the lateral recess 6 of the first stationary lane delimiter 2. The closure element 5 can be lowered onto the pin 9. The stop device 7 serves to precisely position the closure element 5 of the movable lane delimiter 4 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 delimiters. The total height of the closure arrangement h va is approximately 55 cm, and the length of the recess L a is approximately 4.48 m.

[0061] Fig. 9 shows the second end 13 of the movable lane marking element 4 from Figure 1with an articulated device 15. The articulated device enables the movable lane marking element to pivot about a substantially vertical axis.
