Description

[0001] TITLE

[0002] EVENT BARRIER WITH LOCKING DEVICE AND CENTERING DEVICE

[0003] TECHNICAL FIELD

[0004] The present invention relates to an event barrier according to claim 1 and a method for producing an event barrier according to claim 15.

[0005] STATE OF THE ART

[0006] Event barriers are known, for example, from highways, where they provide a barrier between two direction-separated lanes. Such barriers can provide impact protection with a retention level of H1 to H4, preventing a colliding vehicle from crossing into the oncoming lane. At the same time, these barriers should be able to be opened automatically or without power to provide passage for an emergency vehicle in an emergency situation such as an accident. This is typically provided by an event barrier with a pivoting barrier arm that can be pivoted from a closed position to an open position and vice versa. Such an event barrier is known, for example, from EP 3 000 937 A1. To ensure that the barrier arm remains in the closed position under normal conditions, a locking device is often provided.For example, the barrier arm can have a locking element that can lock with a locking receptacle fixed to the roadway. It has been shown that influences such as heating from solar radiation can lead to deformation of the locking device, which negatively affects the locking function.

[0007] PRESENTATION OF THE INVENTION

[0008] It is an object of the present invention to provide an event barrier with a locking device which ensures reliable locking.

[0009] This object is achieved by an event barrier according to claim 1. Thus, an event barrier for arrangement on a roadway is specified, which comprises at least one barrier element comprising a barrier arm and at least one locking device. The barrier arm is pivotally mounted about a pivot axis. The barrier arm can be pivoted about the pivot axis from a closed position, in which the barrier arm extends parallel to the roadway, to an open position, in which the barrier arm extends at an angle to the roadway. The barrier arm can be locked in the closed position by means of the locking device. The event barrier has at least one centering device comprising a centering element and a centering receptacle.When the shut-off arm is moved into the closed position, the centering element can be at least partially accommodated in the centering receptacle, whereby the shut-off arm can be locked centered in the closed position.

[0010] This means that the centering device allows the shut-off arm to be locked centered in the closed position. The term "centered" refers to the fact that the centering device aligns the shut-off arm, thereby ensuring reliable locking.

[0011] In use, the event barrier is preferably located between two retaining elements such as guardrail elements in a central reservation crossing system or a road edge. When the barrier arm is in the open position, a vehicle can pass through the clearance area between the retaining elements. When the barrier arm is in the closed position, the event barrier prevents passage. The event barrier therefore serves to provide a clearance area between the retaining elements so that vehicles from emergency services such as the police, fire brigade or ambulance can pass the retaining elements. The barrier arm can take the form of a guardrail or a guide wall. The pivot axis around which the barrier arm can be pivoted is preferably provided by a pivot bearing on the barrier element that is fixed to the roadway.The pivot axis is preferably substantially parallel to a road surface. The centering element is preferably arranged on the barrier arm and / or immovably arranged on the barrier arm and / or non-pivotable on the barrier arm. The centering element is preferably arranged in the region of a free end of the barrier arm or on the front side of the barrier arm. The centering element is preferably detachably attached to the barrier arm and can be replaced, for example, in the event of wear or an accident. Particularly preferably, the centering element is mechanically connected to the barrier arm and, for example, screwed thereto. The centering element preferably comprises or consists of steel.

[0012] Preferably, the centering mount can be arranged fixedly relative to the roadway. This means that the centering mount is preferably immovable and / or non-pivotable relative to the roadway.

[0013] Preferably, the centering element has an elongated shape and / or extends along a height direction of the shut-off arm that is perpendicular to the longitudinal direction of the shut-off arm.

[0014] Additionally or alternatively, the centering element preferably has a free end and is tapered inwards in the direction of the free end.

[0015] Particularly preferably, the centering element has a first end and an opposite second end. The centering element is preferably attached to the shut-off arm in the region of its first end, and the second end preferably forms a free end.

[0016] The centering element is configured to taper inwardly in the region of its second end toward a central longitudinal axis of the centering element. The centering element is configured to taper inwardly, preferably at an angle of 10° or more, preferably approximately 25°, relative to its central longitudinal axis. Figuratively speaking, the centering element, viewed in longitudinal section, preferably has the shape of a sword blade.

[0017] As will be explained in more detail below, at least one and preferably two of the inwardly tapered outer surfaces of the centering element each form a guide element for the guided reception of the centering element in the centering receptacle. Preferably, the centering element and the centering receptacle each have at least one guide element, so that the centering element can be received in the centering receptacle in a guided manner by means of the guide elements. The guide element of the centering element is preferably an outer surface of the centering element, and the guide element of the centering receptacle is preferably a surface of the centering receptacle that at least partially delimits the centering receptacle. The guide elements of the centering element and the centering receptacle are therefore preferably formed integrally with the centering element or centering receptacle, or in other words, are preferably each a component thereof.

[0018] The centering device can comprise a preferably plate-shaped component, wherein the centering receptacle is a through-opening in the component. Preferably, a clear width of the centering receptacle along a transverse direction of the centering receptacle substantially corresponds to a maximum width dimension of the centering element along a transverse direction of the centering element running perpendicular to the longitudinal direction of the centering element. The component is also known as a flat. The centering receptacle is preferably a slot extending along a transverse direction of the component or flat. The transverse direction of the component or of the centering receptacle preferably runs parallel to the transverse direction of the centering element.The clear width of the centering receptacle along the transverse direction of the centering receptacle, which substantially corresponds to the maximum width extension of the centering element along the transverse direction of the centering element, preferably means that the maximum width extension of the centering element is 10 millimeters or less, in particular approximately 5 millimeters less than the clear width of the centering receptacle.

[0019] The locking device is preferably pivotably mounted relative to the centering element. The locking device is preferably at least partially received in a recess in the centering element. Particularly preferably, the locking device is arranged at least partially within the recess and pivotably within the recess of the centering element. The recess of the centering element preferably extends, starting from the first end of the centering element in the direction of the second end or free end of the centering element, along the longitudinal direction, at least partially through the centering element. In particular, the recess preferably runs centrally at least partially through the centering element.

[0020] The locking device preferably comprises a locking element and a locking receptacle. The locking element is preferably formed on the barrier arm, and the locking receptacle can preferably be arranged stationary relative to the roadway. The locking element can preferably be at least partially received in the locking receptacle and locked to the locking receptacle, whereby the barrier arm can be locked in the closed position. The locking device is preferably designed to form a releasable lock. In the locked state of the locking device, a positive connection preferably forms between the locking element and the locking receptacle.

[0021] The locking element and / or the locking receptacle are preferably non-deformable or non-elastic, but rather dimensionally stable. This means that these components are preferably not deformed during the formation of the locking mechanism. In particular, the locking element and locking receptacle preferably each have at least one engagement element, which can be brought into engagement with one another, preferably releasably. The engagement element of the locking element preferably has the shape of a recess, and the engagement element of the locking receptacle preferably has the shape of a wall region that at least partially delimits the locking receptacle.In the locked state of the locking device, the wall region of the locking receptacle is arranged at least partially within the recess of the locking element and forms a stop with respect to a displacement of the locking element, and consequently of the locking arm, into the open position.

[0022] The locking element is preferably mounted on the barrier arm so as to be pivotable about a pivot axis. The locking element is preferably arranged in the area of ​​the free end of the barrier arm or on the front side of the barrier arm. The locking element preferably comprises or consists of steel.

[0023] Preferably, the locking element is detachably attached to the shut-off arm and can be replaced, for example in the event of wear or an accident. Particularly preferably, the locking element is mechanically connected to the shut-off arm and, for example, screwed. In particular, the locking element is pivotally arranged at least partially within the recess of the centering element and / or is pivotable at least partially into and out of the recess. When the shut-off arm is moved into the closed position, the locking element is preferably pivoted about its pivot axis until it locks within the locking receptacle with the locking receptacle. In particular, the locking element is deflected from an eccentric weight distribution towards the pivot axis until it locks with the locking receptacle.In the locked state, the locking element is preferably again in its eccentric weight distribution with permanent closing pressure. This means that when the barrier arm is transferred to the closed position, the locking element is preferably deflected from its eccentric weight distribution or pivoted about its pivot axis until it locks within the locking receptacle, in particular with its engagement element in the form of the wall area that at least partially delimits the locking receptacle, in particular latches therewith or thus forms an engagement.

[0024] The locking element and the locking receptacle preferably each have at least one guide element, which are arranged and configured such that, when the shut-off arm is transferred into the closed position, the guide element of the locking element is guided along the guide element of the locking receptacle, and the locking element is pivoted about a pivot axis. In other words, when the shut-off arm is transferred into the closed position, the guide element of the locking receptacle preferably presses against the guide element of the locking element and pushes it away, which leads to a pivoting of the locking element about its pivot axis.

[0025] The guide element of the locking element is preferably an outer surface of the locking element. The guide element of the locking receptacle is preferably a surface that at least partially defines the locking receptacle. Particularly preferably, the guide element of the locking receptacle is a surface of the wall region that at least partially defines the locking receptacle, or of the engagement element of the locking receptacle.

[0026] Furthermore, it is preferred that the locking receptacle of the locking device and the centering receptacle of the centering device are arranged within a common plane and / or are provided by a common component. Additionally or alternatively, it is preferred that the locking receptacle at least partially corresponds to the centering receptacle, and vice versa. In particular, the centering receptacle in the form of the through opening in the previously described component at least partially also provides the locking receptacle, and vice versa. For example, the slot in the component or flat can at least partially provide both the centering receptacle and the locking receptacle.

[0027] Furthermore, it is preferred that the wall region providing the engagement element of the locking receptacle is at least partially a wall region delimiting the centering receptacle or a wall region of the component.

[0028] Furthermore, it is preferred that the guide element of the locking receptacle and the guide element of the centering receptacle are formed adjacent to one another and, in particular, are at least partially adjacent surfaces of the surfaces delimiting the centering receptacle or locking receptacle, in particular surfaces of the wall regions just described.

[0029] In the case of the centering receptacle or locking receptacle in the form of the slot in the component or flat, wall areas or surfaces of the shorter sides of the slot preferably form the guide elements of the centering receptacle and the wall area(s) or surfaces of the longer side of the slot preferably form the guide elements of the locking receptacle.

[0030] In other words, the wall areas or surfaces of the centering receptacle preferably run perpendicular to the wall area(s) or surfaces of the locking receptacle.

[0031] Preferably, the locking element, in its eccentric weight position and / or at least in the closed position of the barrier arm, extends along a vertical direction of the barrier arm that runs perpendicular to the longitudinal direction of the barrier arm. The eccentric weight position of the locking element preferably always presses the locking element into its locked state. In other words, the locking element is preferably designed such that its center of gravity preferably presses the locking element into the locked state in the non-pivoted state or in the eccentric weight position.

[0032] The locking element preferably has a free end and at least one side tapering inward toward the free end. In particular, the locking element has a first and a second end, which are opposite one another with respect to a longitudinal direction of the locking element. The second end of the locking element is preferably a free end. The locking element is preferably pivotally attached to the barrier arm in the region of its first end.

[0033] The locking element preferably has at least one side which tapers inwardly towards the free end or the second end of the locking element. The side of the locking element is preferably designed to taper inwardly at an angle of 10° or more, preferably 25° or more, relative to its central longitudinal axis. The previously described guide element of the locking element is preferably provided by the outer surface of this inwardly tapered side of the locking element. The locking receptacle, in particular its guide element or the surface which at least partially delimits the locking receptacle or provides the engagement element, is preferably inclined correspondingly to the inwardly tapered side of the locking element.Or in other words, the guide elements of the locking receptacle and the locking element are preferably surfaces or bevels that are inclined relative to one another, so that when the barrier arm is moved into the closed position, the locking element is pushed away or pivoted until it locks with the locking receptacle or engages with its engagement element or wall element.

[0034] Figuratively speaking, the locking element, viewed in longitudinal section, preferably has a pawl shape and has a substantially rectangular or cylindrical neck portion followed by a trapezoidal or triangular head portion. The first end of the locking element is preferably in the neck portion, and the second end or free end of the locking element is preferably in the head portion.

[0035] As explained in more detail below, the event barrier can be a single-arm or a double-arm event barrier. The design of the locking element in the case of the double-arm event barrier preferably differs from the design of the locking element in the case of the single-arm event barrier in that the locking element has an extension in the region of its first end, which, when the locking element is in the closed position, extends along the longitudinal direction of the barrier arm. Or in other words, the extension preferably extends perpendicular to the previously described neck section of the locking element. In other words, the locking element in this case can have the trapezoidal or triangular neck section and an overall L-shaped neck section.

[0036] The locking device preferably has an actuating lever for unlocking the locking device, so that the shut-off arm can be moved from the closed position to the open position by manually actuating the actuating lever. Additionally or alternatively, the locking device preferably has at least one actuating element that can be actuated by a drive device, so that the shut-off arm can be automatically moved from the closed position to the open position.

[0037] Preferably, the actuating lever is arranged on the locking element and extends outwards away from the locking element, in particular, so that it can be grasped by a user on the outside of the event barrier and manually actuated. Manual actuation of the actuating lever preferably leads to a pivoting of the locking element, so that the locking of the locking element with the locking receptacle is released. Analogously, automatic actuation of the actuating element preferably leads to a pivoting of the locking element, whereby the locking of the locking element with the locking receptacle is released. In both cases, i.e., both manual and automatic, the engagement between the engagement elements is released, or the recess of the locking element is guided out of the wall region of the locking receptacle, in particular pivoted away from it.

[0038] The operating lever is preferably arranged and configured such that a user's pulling force on the operating lever vertically upwards, or in other words along the vertical direction of the barrier arm, leads to a pivoting of the locking element. This is preferably achieved by the guide elements of the engagement elements of the locking receptacle and the locking element described above in the form of the inclined surfaces or bevels. In the case of the latch-shaped locking element, the operating lever is preferably arranged on the head section and extends away from the head section parallel to the neck section. This arrangement is preferred for both the locking element of the single-arm event barrier and the double-arm event barrier.

[0039] The drive device is preferably an electric drive device, for example a motor with a spindle drive or a hydraulic cylinder or pneumatic cylinder. The actuating element of the locking device is preferably arranged such that it is subjected to a compressive force by the drive device and is thereby pivoted. The actuating element is preferably arranged on the locking element. In particular, the actuating element is a preferably plate-shaped component which is arranged on the locking element and can be subjected to a compressive force by the drive device. In the case of a latch-shaped locking element, the actuating element is preferably arranged on the neck section.

[0040] In the case of a single-armed event barrier, the actuating element is particularly preferably arranged in the neck section, preferably in the region of the engagement element or the recess of the locking element, and extends along the vertical direction of the barrier arm in the closed position. Furthermore, in this case, it is preferred that the drive device is arranged and configured such that it applies a compressive force to the actuating element that is directed along the longitudinal direction of the barrier arm.

[0041] In the case of the double-armed event barrier, the actuating element is preferably arranged in the neck section, but in its extension. In other words, the actuating element is preferably arranged in the region of a free end of the L-shaped neck section and, in the closed position, preferably extends along the longitudinal direction of the barrier arm. Furthermore, in this case, it is preferred that the drive device be arranged and configured such that it applies a compressive force to the actuating element that is directed perpendicular to the longitudinal direction or along the vertical direction of the barrier arm.

[0042] The event barrier is preferably a so-called single-arm event barrier or a so-called double-arm event barrier. A single-arm event barrier is also referred to as a single barrier or single-barrier. A double-arm event barrier is also referred to as a double barrier. In the first case of a single-arm event barrier, the event barrier preferably comprises a second barrier element, which can preferably be arranged stationary relative to the roadway. This second barrier element is also referred to as a fixed part. The centering receptacle, in particular the previously described component, is preferably arranged on the second barrier element. The locking receptacle is therefore also preferably arranged on the second barrier element.Particularly preferably, the previously described component comprising the centering receptacle and locking receptacle is arranged in the region of a free end of the second barrier element or on the front side of the second barrier element. Preferably, the component is releasably attached to the second barrier element and can be replaced, for example, in the event of wear or an accident. Particularly preferably, the component is mechanically connected to the second barrier element, for example, by screwing. The component preferably comprises or consists of steel.

[0043] The barrier arm preferably has a lower end facing the roadway, and the centering element does not extend beyond the lower end, as viewed in the vertical direction of the barrier arm. This means that the free end of the centering element is preferably arranged in the region of the lower end, in particular flush with the lower end, or above the lower end of the barrier arm, as viewed in the vertical direction of the barrier arm. In other words, the centering element preferably does not extend beyond the lower end of the barrier arm.

[0044] In the second case of the double-armed event barrier, the event barrier preferably comprises a second barrier element, a second centering device, and a second locking device. All statements regarding one of these devices preferably apply to two (or more) of these devices. This means that the second barrier element preferably comprises a second barrier arm, which can be pivoted about a second pivot axis from the closed position to the open position and can be locked centered in the closed position by means of the second locking device and the second centering device. In this second case, too, the barrier arm preferably has a lower end facing the roadway, although the centering element preferably extends beyond the lower end with respect to the vertical direction of the barrier arm.This means that the free end of the centering element preferably protrudes beyond the lower end of the barrier arm. The centering receptacles of the two centering devices, and consequently preferably also the locking receptacles of the locking devices, are preferably arranged in the roadway. Particularly preferably, one of the centering receptacles and one of the locking receptacles are formed in a previously described component, wherein this component is arranged in the roadway, in particular, is concreted into the roadway. Instead of two components, a single component comprising both centering receptacles and both locking receptacles can also be provided.The component(s) are preferably arranged in such a way that, in the closed position of the shut-off arms, they come to lie in the region of the free ends or end faces of the two shut-off arms and thus enable the centering elements to be received in their centering receptacles or the locking elements in their locking receptacles.

[0045] Unless otherwise stated, explanations regarding the single-arm event barrier preferably apply to the double-arm event barrier and vice versa.

[0046] The (single-arm or double-arm) event barrier preferably further comprises at least one tensile strength device for absorbing longitudinal forces along the longitudinal direction of the barrier arm in the closed position and / or for absorbing transverse forces along a transverse direction of the barrier arm running transversely to the longitudinal direction of the barrier arm in the closed position.

[0047] The tensile strength device preferably comprises at least one component with at least one recess for positive and / or non-positive connection with at least one connecting element.

[0048] The component is preferably arranged stationary relative to the roadway. Furthermore, it is preferred that, in the case of a single-armed event barrier, the component is arranged on the second barrier element, i.e., the fixed part. For example, the component can be bolted and / or welded to the second barrier element. In the case of a double-armed event barrier, it is preferred that the component is arranged in the roadway, for example, encased in concrete or connected to a floor frame encased in concrete in the roadway, for example, bolted to it. The component of the tensile strength device is preferably plate-shaped. The connecting element for the positive and / or non-positive connection to the recess in the component is preferably a mechanical connecting element such as a bolt. The component preferably has two or more recesses into which two or more connecting elements are received.

[0049] The recess(es) in the component and the connecting element(s) are preferably arranged in such a way that, when the barrier arm is in the closed position, a connecting element is received in a recess in the component. Consequently, it is preferred that a number of connecting elements corresponds to a number of recesses in the component and / or that, when the barrier arm is in the closed position, the connecting elements and the recesses in the component are at least partially congruent with one another along the vertical direction of the barrier arm. For example, one or more connecting elements such as bolts can be screwed laterally to the barrier arm for this purpose. These bolts, when the barrier arm is in the closed position, are received in the recesses of the component welded to the fixed part (single-arm event barrier) or in the recesses of the base part arranged in the roadway (double-arm event barrier).

[0050] The tensile strength device is preferably formed separately from the centering device and the locking device. As a result, no tension is exerted on the centering device and the locking device.

[0051] The event barrier may include additional tensile strength devices. For example, a connecting element such as a T-piece may be formed on one end face of the barrier arm, which is received in a corresponding recess in one end face of the second barrier element or fixed part in the case of a single-arm event barrier, or in a corresponding recess in one end face of the second barrier arm in the case of a double-arm event barrier.

[0052] In a further aspect, a method for producing an event barrier for arrangement on a roadway is provided.

[0053] The method comprises the steps of i) providing at least one barrier element comprising a barrier arm, and ii) providing at least one locking device. The barrier arm is pivotally mounted about a pivot axis. The barrier arm can be pivoted about the pivot axis from a closed position, in which the barrier arm extends parallel to the roadway, to an open position, in which the barrier arm extends at an angle to the roadway. The barrier arm can be locked in the closed position by means of the locking device. The event barrier has at least one centering device comprising a centering element and a centering receptacle. The centering element can be at least partially received in the centering receptacle when the barrier arm is transferred into the closed position, whereby the barrier arm can be locked centered in the closed position.

[0054] The event barrier is preferably the one described above. Statements regarding the event barrier therefore preferably apply to the process for creating the event barrier, and vice versa.

[0090] DESCRIPTION OF PREFERRED EMBODIMENTS

[0091] With reference to the figures, aspects of the event barriers 1 according to the invention will now be illustrated.

[0092] Figures 1a-2 and 5-17 each show aspects of an event barrier 1 according to a first embodiment, and Figures 3-4 and 18-24 each show aspects of an event barrier 1 according to a second embodiment. The event barrier 1 according to the first embodiment is a single-arm event barrier, and the event barrier 1 according to the second embodiment is a double-arm event barrier.

[0093] As can be clearly seen from Figures 1a to 4, for example, the event barriers 1 of both embodiments are each an event barrier 1 which is arranged on a roadway 2 and each comprises at least one barrier element 3 comprising a barrier arm 4 and at least one locking device 5. The barrier arm 4 is pivotally mounted about a pivot axis Sa, wherein the barrier arm 4 can be pivoted about the pivot axis Sa from a closed position, in which the barrier arm 4 extends parallel to the roadway 2 (see, for example, Figure 4), into an open position, in which the barrier arm 4 extends at an angle to the roadway 2 (see, for example, Figure 3).

[0094] As can be seen from Figures 5 and 18, the barrier arm 4 can assume various open positions. For example, the barrier arm 4 can assume a fully open open position, wherein the barrier arm 4 extends substantially perpendicular to the roadway 2, or a partially open open position, wherein the barrier arm 4 extends at an angle of approximately 45° to the roadway 2. In particular, when the barrier arm 4 is transferred from the fully open open position to the closed position, it continuously assumes this and further partially open open positions, wherein the angle between the barrier arm 4 and the roadway 2 becomes increasingly smaller. The same applies to the transfer from the closed position to the fully open open position, wherein the angle between the barrier arm 4 and the roadway 2 becomes increasingly larger.

[0095] The barrier arm 4 can be locked in the closed position by means of the locking device 5. Furthermore, the event barrier 1 has at least one centering device 6 comprising a centering element 7 and a centering receptacle 8. The centering element 7 can be at least partially received in the centering receptacle 8 when the barrier arm 4 is moved into the closed position, whereby the barrier arm 4 can be locked centered in the closed position.

[0096] As can be seen, for example, in Figures 1a-2, the locking device 5 has a locking element 24 and a locking receptacle 25, wherein the locking element 24 is formed on the barrier arm 4 and the locking receptacle 25 is arranged stationary relative to the roadway 2. In the closed position of the barrier arm 4, the locking element 24 is partially received in the locking receptacle 25 and locked to the locking receptacle 25, whereby the barrier arm 4 is locked in the closed position, see, for example, Figure 13. For this purpose, the locking element 24 and the locking receptacle 25 each have an engagement element 26; 27, which engage with one another in a releasable manner.

[0097] The engagement element 26 of the locking element 24 is a recess extending into the locking element 24, and the engagement element 27 of the locking receptacle 25 is a wall region partially delimiting the locking receptacle 25, see Figures 2, 11a, 13, 20, and 21a. In the locked state of the locking device 5 and consequently with the closing arm 4 in the closed position, the wall region 27 of the locking receptacle 25 is at least partially arranged within the recess 26 of the locking element 24 and forms a stop with respect to a displacement of the locking element 24, and consequently of the shut-off arm 4, into the open position.

[0098] As previously mentioned, the event barrier 1 according to the invention can be a single-arm or a double-arm event barrier 1. The single-arm event barrier 1 comprises a second barrier element 3a, which is arranged stationary relative to the roadway 2, see Figures 2, 5, 12, 13, 15. The centering receptacle 8 and the locking receptacle 25 are arranged on the second barrier element 3a, specifically in the region of a free end or end face 42 of the second barrier element 3a. The barrier arm 4 has a lower end 41 facing the roadway 2, and wherein the centering element 7 does not extend beyond the lower end 41 with respect to a height direction Ha of the barrier arm 4 running perpendicular to the longitudinal direction La of the barrier arm 4, so that a free end 11 of the centering element 7 is flush with the lower end 41 of the barrier arm 4 with respect to the height direction Ha of the barrier arm 4, see e.g. Figure 1b.The double-armed event barrier 1 also comprises a second barrier element 3a, and furthermore a second centering device 6a and a second locking device 5a, see Figures 3-4, 18, 22 and 24. All statements regarding the centering device 6 and the locking device 5 apply analogously to the second centering device 6a and the second locking device 5a and vice versa (although, for the sake of clarity, reference is sometimes made solely to one of the devices). Unless otherwise stated, statements regarding the single-armed event barrier 1 also apply analogously to the double-armed event barrier 1 and vice versa. Furthermore, for the sake of clarity, the reference symbols for the second devices have been omitted in some cases, although they are used in the figures.

[0099] Unlike the single-arm event barrier 1, the second barrier element 3a of the double-arm event barrier 1 comprises a second barrier arm 4a, which is pivotable about a second pivot axis Sva from the closed position to the open position and is locked in the closed position by means of the second locking device 5a and the second centering device 6a. In this second case, the barrier arm 4 or the barrier arms 4, 4a preferably each have a lower end 41, 41a facing the roadway 2, although the centering element 7, 7a extends beyond the lower end 41, 41a with respect to the height direction Ha of the barrier arm 4, 4a, see Figures 22-24.Unlike the single-armed event barrier 1, the centering receptacles 8, 8a of the two centering devices 6, 6a as well as the locking receptacles 25, 25a of the locking devices 5, 5a in the double-armed event barrier 1 are arranged in the roadway 2.

[0100] In both event barriers 1, the centering element 7 is mechanically connected to the barrier arm 4 in a non-displaceable and non-pivotable manner in the region of a free end or end face 9 of the barrier arm 4 and is screwed thereto by means of screws 10, see, for example, Figures 1a-1b and 3. As can be seen from these figures and also from Figures 6a-6c, 14 and 19a-19b, the centering element 7 has an elongated shape and extends along the height direction Ha of the barrier arm 4. Furthermore, the centering element 7 is designed to taper inwards towards its free end 11. This means that the centering element 7 has a first end 12 and an opposite second end 13. The centering element 7 is fastened to the barrier arm 4 in the region of its first end 12, and the second end 13 forms the free end 11.The centering element 7 is designed to taper inwards in the region of its second end 13 or free end 11 in the direction of a central longitudinal axis Lz of the centering element 7, see in particular Figures 1b, 6a and 19a. The centering element 7 is designed to taper inwards at an angle az of approximately 25° with respect to its central longitudinal axis Lz. Furthermore, the centering element 7 has a recess 23 which extends from the first end 12 of the centering element 7 in the direction of the second end 13 or free end 11 of the centering element 7 along the longitudinal direction or central longitudinal axis Lz of the centering element 7, partially through the centering element 7.

[0101] The centering element 7 of the single-arm event barrier 1 and the double-arm event barrier 1 is identically designed except for the slight curvature in the case of the centering element 7, 7a of the double-arm event barrier 1 (see Figures 6c and 19b). This means that while the centering element 7 in the case of the single-arm event barrier 1 is planar or non-curved, a lower region 7b of the centering element 7, 7a of the double-arm event barrier 1, facing the roadway 2, is curved away from a planar upper region 7a of the centering element 7, 7a by an angle of curvature ak of approximately 20°. The lower region 7b is curved in the direction of the barrier arm 4, 4a (see, for example, Figures 22 and 24).This curvature is provided because, unlike the single-arm event barrier, the centering element 7, 7a of the double-armed event barrier 1 is arranged offset from a pivot point around which the barrier arm 4, 4a is pivoted, whereby a radius of rotation of the centering element 7, 7a changes when it is received in the centering receptacle 8, 8a.

[0102] In both the single-arm and the double-arm event barrier 1, the centering receptacle 8 is arranged stationary relative to the roadway 2. As can be clearly seen from Figures 2, 8-9, and 20, for example, the centering device 6 comprises a plate-shaped component 22, and the centering receptacle 8 is a continuous opening in the component 22. A clear width Ba of the centering receptacle 8 along a transverse direction Qa of the centering receptacle 8 essentially corresponds to a maximum width extension Be of the centering element 7 along a transverse direction Qz of the centering element 7 running perpendicular to the longitudinal direction or central longitudinal axis Lz of the centering element 7.

[0103] In the single-arm event barrier 1, the component 22 is arranged in the region of a free end 42 or end face of the second barrier element 3a and is screwed thereto. In the double-arm event barrier 1, the components 22, 22a are arranged in the roadway 2, in particular concreted into the roadway 2. The components 22, 22a are arranged such that, in the closed position of the barrier arms 4, 4a, they come to rest in the region of the free ends or end faces 9, 9a of the two barrier arms 4, 4a, thereby enabling the centering elements 7, 7a to be received in their centering receptacles 8, 8a and the locking elements 24, 24a to be received in their locking receptacles 25, 25a.

[0104] The centering element 7 and the centering receptacle 8 of the single-armed as well as the double-armed event barrier 1 each have two guide elements 16; 17 and 18; 19, respectively, so that the centering element 7 can be received in the centering receptacle 8 by means of the guide elements 16-19, see Figures 1b and 2. As can be further seen from these figures, the guide elements 16; 17 of the centering element 7 are each an outer surface 14; 15 of the centering element 7, and the guide elements 18; 19 of the centering receptacle 8 are each a surface 20; 21 of the centering receptacle 8 that at least partially delimits the centering receptacle 8.

[0105] As can be seen from Figures 1a-1b, 13, 17, 22, and 24, the locking element 24 in both event barriers 1 is arranged in the region of the free end 9 or end face of the barrier arm 4 and is pivotably mounted about a pivot axis Sv. In particular, the locking element 24 is at least partially received in the recess 23 of the centering element 7 and pivotable with respect to the centering element 7, wherein the locking element 24 can be pivoted in and out of the recess 23 in certain regions. When the barrier arm 4 is moved into the closed position, the locking element 24 is pivoted about its pivot axis Sv until it locks within the locking receptacle 25 with the locking receptacle 25.

[0106] The pivoting of the locking element 24 during transfer from the open position to the closed position (and vice versa) is indicated in Figures 12, 17, 22 and 24 (right locking element 24a). The locked state of the locking element can be seen, for example, in Figures 13 and 24 (left locking element 24). As can be seen from these figures, when the shut-off arm 4, 4a is transferred into the closed position, the locking element 24, 24a is deflected from its eccentric weight distribution or pivoted about its pivot axis Sv, Sva until it locks, in particular latches, within the locking receptacle 25, 25a with its engagement element 27, 27a in the form of the wall region at least partially delimiting the locking receptacle 25, 25a.The locking element 24, 24a and the locking receptacle 25, 25a each have a guide element 28, 28a; 29, 29a, which are arranged and designed such that when the shut-off arm 4, 4a is transferred into the closed position, the guide element 28, 28a of the locking element 24, 24a is guided along the guide element 29, 29a of the locking receptacle 25, 25a, and the locking element 24, 24a is pivoted about a pivot axis Sv, Sva. The guide element 28, 28a of the locking element 24, 24a is an outer surface of the locking element 24, 24a. The guide element 29, 29a of the locking receptacle 25, 25a is here a surface of the wall region partially delimiting the locking receptacle 25, 25a or of the engagement element 27, 27a of the locking receptacle 25, 25a.The locking element 24, 24a extends in its eccentric weight position as well as in the closed position of the shut-off arm 4, 4a, wherein the locking element 24, 24a is again in the eccentric weight position, along the height direction Ha of the shut-off arm 4, 4a.

[0107] Furthermore, the locking element 24 has a free end 30 and a side 33 tapering in the direction of the free end 30, see, for example, Figures 11a and 21a. Furthermore, the locking element 24 has a first end 31 and a second end 33, wherein the locking element 24 is pivotally attached to the shut-off arm 4 in the region of the first end 31 and the second end 32 forms the free end 30. The inwardly tapered side 33 of the locking element 24 is designed to taper inwards by an angle av of approximately 25° with respect to an extension direction Ev of the locking element 24 running perpendicular to the pivot axis Sv of the locking element 24. The previously described guide element 28 of the locking element 24 is provided by the outer surface of this inwardly tapering side 33 of the locking element 24.The locking receptacle 25, in particular its guide element 29 or the surface which at least partially delimits the locking receptacle 25 or provides the engagement element 27, is inclined accordingly towards the inwardly tapering side 33 of the locking element 24.

[0108] The locking element 24 has, in longitudinal section, a substantially rectangular neck portion 34 followed by a trapezoidal head portion 35. The first end 31 of the locking element 24 is arranged in the neck portion 34 and the second end 32 or free end 30 of the locking element is arranged in the head portion 35.

[0109] As can be seen from a comparison of Figures 11a and 21, the design of the locking element 24 is somewhat different in the case of the single-arm and double-arm event barrier 1. Thus, the locking element 24 of the double-arm event barrier 1 has an extension 36 in the region of its first end 31, which, when the locking element 24 is in the closed position, extends along the longitudinal direction La of the barrier arm 4. In other words, the extension 36 preferably extends perpendicular to the previously described neck portion 34 of the locking element 24.

[0110] The locking device 5 of the single-armed as well as the double-armed event barrier 1 each has an actuating lever 37 for unlocking the locking device 5, so that the barrier arm 4 can be moved from the closed position to the open position by manually actuating the actuating lever 37, see e.g. Figures 1b, 12, 13, 17, 23 and 24. The actuating lever 37 is arranged on the locking element 24, specifically on the head section 35 and extends parallel to the neck section 34 away from the head section 35. A pulling force of a user on the actuating lever 37 vertically upwards or in other words along the height direction Ha of the shut-off arm 4 leads to a pivoting of the locking element 24, which is caused by the guide element 28 of the locking element 24 and the guide element 29 of the locking receptacle 25 in the form of the inclined surfaces or bevels.

[0111] The locking device 5 also has at least one actuating element 38 for each of the two event barriers, which can be actuated by a drive device 39, so that the barrier arm 4 can be automatically moved from the closed position to the open position. In particular, in the case of a single-arm event barrier 1, the actuating element 38 is arranged on the neck section 34, specifically in the region of the engagement element 26 or the recess of the locking element 24, and extends, in the closed position of the barrier arm 4, along the height direction Ha of the barrier arm 4. Furthermore, the drive device 39 is arranged and designed such that it applies a compressive force to the actuating element 38, which is directed along the longitudinal direction La of the barrier arm 4.In the case of the double-armed event barrier 1, the actuating element 38 is also arranged in the neck section 34, but in its extension 36, and extends in the closed position along the longitudinal direction La of the barrier arm 4. Furthermore, the drive device 39 is arranged and designed such that it applies a compressive force to the actuating element 38 which is directed perpendicular to the longitudinal direction La or along the height direction Ha of the barrier arm 4.

[0112] Both the single-arm and the double-arm event barrier 1 each have a tensile strength device 43 for absorbing longitudinal forces along the longitudinal direction La of the barrier arm 4 in the closed position and for absorbing transverse forces along a transverse direction Q of the barrier arm 4 running transversely to the longitudinal direction La of the barrier arm 4 in the closed position.

[0113] The tensile strength device 43 comprises a plate-shaped component 44 with recesses 45 for positive and non-positive connection with connecting elements 50 in the form of bolts, see e.g. Figures 2, 7a, 8, 10, 13, 14, 17, 20, 23 and 24. The component 44 is arranged stationary to the roadway 2 and, in the case of the single-armed event barrier 1, is attached to the second barrier element 3a, in particular in the region of a lower end 51 of the second barrier element 3a facing the roadway 2 (see Figure 2), here screwed thereto, or, in the case of the double-armed event barrier 1, is concreted into the roadway 2.

[0114] The single-arm and the double-arm event barrier 1 each comprise a further tensile strength device 46. As can be seen from Figures 1b, 22 and 24, a connecting element in the form of a T-piece 47 is formed on the front side in the region of an upper end 49 of the barrier arm 4, which is received in a corresponding recess 48 in a front side of the second barrier element 3a in the case of the single-arm event barrier 1 or the second barrier arm 4a in the case of the double-arm event barrier 1.
