AI Technical Summary
Existing bollards with warning devices often require the blocking body to move fully into the blocking position before the optical warning signal is visible, which can lead to increased risk of collision or stumbling, as the lighting devices are either embedded in the upper side and prone to damage or only visible during continuous movement.
A bollard design where the light source is aligned orthogonally to the axis of movement and positioned to emit an optical warning signal only when the blocking body is partially extended, allowing it to project beyond the base body, providing a visible warning before fully extending into the blocking position, and accompanied by an acoustic signal for enhanced safety.
This configuration reduces the risk of collision and stumbling by ensuring the optical warning is perceivable earlier, allowing sufficient time for awareness before the bollard fully extends, thereby enhancing safety and reducing wear on the lighting components.

BOLLARD WITH WARNING DEVICE AND METHOD FOR ACTIVATING A BOLLARD
[0001] The invention relates to a bollard with a drive, a base body, a locking element, a warning device and a light source, wherein the base body is connectable to the ground and the locking element is movably arranged on the base body by means of the drive along a direction of movement over a locking height between an opening position and a locking position, an upper surface of the locking element in the opening position is essentially flush with a surface of the base body which is essentially flush with the ground and in the locking position projects beyond the base body at the locking height and the locking element is moved out of the ground in the locking position and has a lateral surface arranged essentially parallel to the direction of movement.wherein the light source is arranged in a warning area associated with the upper side above a warning height on the surface of the cladding and is configured to emit an optical warning signal oriented essentially orthogonally to the axis of movement when activated. The invention further relates to a method for actuating such a bollard.
[0002] Known bollards, which move a barrier element relative to a base body (e.g., installed underground) by means of a drive mechanism, often also feature Lighting devices are used to warn people, such as motorists. These warning devices serve either to mark the locking element in the locked position and / or to warn people if the locking element moves relative to the base. This prevents, for example, a vehicle from driving onto the locking element while it is in the locked position and being lifted and / or damaged by it.
[0003] Furthermore, acoustic warning devices are known which, for example, emit a beep or other acoustic warning signal when the locking element is moved relative to the base body.
[0004] Corresponding warning devices with optical signals are either embedded in a top surface of the locking body, which necessitates the use of a transparent cover disc that is scratched and / or damaged when the locking bollard is used, or such lighting devices embedded in a surface of the locking body are only perceptible when the locking body, by means of the drive, fully performs the normally continuous movement in the direction of the locking position.
[0005] From DE 10 2017 006 232 Al a bollard device with display is known, wherein a corresponding bollard has a display device arranged over a full surface on a lateral surface in the form of a It has displays. A warning sequence can only be displayed when the bollard is extended.
[0006] The EP 2 161 377 A2 of fenbart describes a warning bollard. Signal lights are mounted on the warning bollard, which can be activated with a flashing sequence when the bollard column is moved. Additionally, reflectors are mounted on the bollard, which provide an extra warning effect through reflection. An acoustic alarm is also included.
[0007] The KR 1020120043413 A describes a warning bollard with a rack and pinion drive. Warning lights are arranged in the cover surface.
[0008] The purpose of the invention is to improve the state of the art.
[0009] The problem is solved by a bollard comprising a drive, a base body, a locking element, a warning device, and a light source, wherein the base body is connectable to the ground and the locking element is movably arranged on the base body by means of the drive along a direction of movement over a locking height between an opening position and a locking position, an upper surface of the locking element in the opening position being essentially flush with a surface of the base body that is essentially flush with the ground, and in the locking position projecting beyond the base body at the locking height, and the locking element being moved out of the ground in the locking position, and a substantially parallel to the The locking element has a lateral surface arranged in the direction of movement, wherein the light source is arranged in a warning area associated with the top surface above a warning height on the lateral surface and is configured to emit an optical warning signal oriented essentially orthogonally to the axis of movement in an activated state, wherein the locking element is designed to be movable along the direction of movement by means of the drive for a warning sequence into a warning position that is partially moved out of the base body relative to the opening position and is at least temporarily stationary for a warning period, and the warning position is designed in such a way thatthat essentially only the warning area in the warning position is visible above the base body for the warning period, and that the emission of the optical warning signal, which is essentially orthogonal to the axis of movement, in the warning position is only made possible by a protrusion of the light source above the base body.
[0010] The core idea of the invention is that the activatable light source on the outer surface of the barrier is oriented essentially orthogonally to the axis of movement, and that before the barrier bollard actually extends into the locking position, it is only extended a short distance along the axis of movement, namely a distance corresponding, for example, to the height of the light source on the outer surface, and then remains in this warning position for a warning period. Thus, an approaching person can detect the activated light source. They can perceive and, for example, recognize from the type and design of the visual warning signal that the bollard is subsequently extending. The warning height might be, for example, only 5 mm, only 10 mm, or only 20 mm, corresponding to, for example, only 1%, 2%, 5%, or 10% of a fully extended height in the locking position. For example, after a warning period has elapsed, the bollard's drive can be controlled in such a way that the bollard is moved further towards the locking position, so that the locking mechanism is engaged if the relevant persons have already been warned by the warning sequence.
[0011] The following terms are explained in this context:
[0012] A "barrier bollard" is a mechanical device designed to be retracted into a subsurface, such as the ground in a parking lot or an interior space, in order to block off specific areas by extending the bollard. Such barrier bollards are used, for example, as lifting bollards to keep parking spaces clear or to temporarily block emergency access routes. For this purpose, such a barrier bollard has a "drive," such as a hydraulic, electric, or servo-electric drive, which, supported by a "base," allows the movement of a corresponding "barrier element." The base is, for example, a pot-shaped receptacle that is installed in the subsurface and secured, for instance, by a foundation. The bollard is secured, while the locking element forms a movable part that can be moved relative to the base body along a "direction of movement," for example, along a substantially vertical axis. The bollard also features a "warning device," a means of warning, for example, motorists and / or pedestrians. This warning device may include both visual and acoustic means. In particular, the warning device includes a "light source," such as an LED strip, illuminated points, or the like, by means of which light can be emitted.
[0013] The bollard is characterized by a "barrier height" along which the barrier element is movably arranged on the base between an "open position," i.e., a position essentially completely recessed underground, and a "locked position" with the barrier element essentially fully extended. A "top" of the barrier element is, for example, a flat side of the barrier element, visible underground even in the open position, which is essentially flush with a "surface" of the base, i.e., a surface of the base that is, for example, essentially embedded in the ground and still perceptible to a person. A "shell surface" of the barrier element is essentially oriented parallel to the direction of movement and is, for example, cylindrical or prismatic. In this case, the shell surface is, in particular, a surface in the locked position. Visible or partially visible surface of the locking element during a transition from the opening position to the locking position, which also serves, for example, as a guide surface for the locking element in the base body or has corresponding guide means for guiding the locking element in the base body.
[0014] A "warning zone" is a sub-area of the surface, which is arranged, particularly starting from the top or adjacent to the surface, so that a "warning height," i.e., a partial height of the surface extending from the top, can be illuminated or marked by the light source with, for example, an optical warning signal. This "optical warning signal" is, for example, a luminous color, a luminous sequence, or a sequence of luminous patterns from the light source, which is then emitted essentially orthogonally to the axis of movement, i.e., essentially parallel to the surface and / or the substrate, in order to warn, for example, a person or a vehicle driver. An "activated state" is the state in which the light source actively emits light, and / or, for example, a period of time in which the light source repeatedly emits a sequence of light signals.
[0015] A "warning sequence" describes a specific, particularly essential, sequence of movements during which the locking element is partially moved outwards relative to the opening position, in particular by only 1%, 2%, 5% or even 10%. The locking height is adjusted so that, for a specific, relatively short period of, for example, 1 second, 2 seconds, 5 seconds, 10 seconds, or even 20 seconds, depending on the application, which is referred to as the "warning time," an intermediate position between the opening position and the locking position is assumed, at least temporarily. This intermediate position is referred to as the "warning position." In this "warning position," it is significantly further towards the opening position than towards the locking position, as mentioned above. In this warning position, essentially only the warning area within the warning time extends above the warning height above the base body."Essentially exclusively" means that only the absolutely necessary height of the warning area or warning zone protrudes above the base body as the absolutely necessary height of the partial height of the height of the blocking position, so that in particular a person is prevented as far as possible, a car driving onto it is still possible without danger and yet the light source can emit the corresponding warning signal to warn people.
[0016] To enable a warning signal to be issued around a corresponding area surrounding the perimeter of the bollard, the light source surrounds a circumference of the lateral surface at least 90°, at least 120°, at least 180°, and / or, in particular, substantially completely. Angle specifications here refer to full angles of 360°. In this arrangement, for example, a 360° warning signal can be emitted if the The light source essentially completely surrounds the circumference of the lateral surface.
[0017] In this context, "circumference" refers to a portion of the lateral surface measured around the direction of movement.
[0018] In one embodiment, the light source is designed to emit a colored, in particular a red, a yellow and / or a blue, optical warning signal and / or an optical warning signal with freely selectable, in particular changing, color.
[0019] This design allows the light source to be adapted to specific situations, applications, or, for example, color concepts in the area of the background, if, for instance, the bollard is to be integrated into an existing color concept in front of a building.
[0020] In order to keep the power consumption of the bollard as low as possible, the light source has an LED, several LEDs and / or an LED strip and / or a light guiding device, wherein the light guiding device is designed in particular to direct the optical warning signal emitted by the light source in a direction essentially parallel to the direction of movement, in particular to generate a secondary warning signal.
[0021] A "light guiding device" is, in particular, a translucent means designed to guide light at interfaces by means of total internal reflection, which, for example, is ring-shaped or partially ring-shaped around the circumference. The light guide is arranged within the locking element and is embedded or partially embedded in the surface of the base body, so that, for example, when the light source is activated to emit a warning signal as a secondary warning signal using the same light source, additional marking in the area of the surface is possible even while the warning position is being assumed. For this purpose, the light guide overlaps with the light source along the direction of movement, for example, in the opening position, and this overlap is maintained, in particular, until the warning position is partially or completely reached, due to the positioning and design of the light guide.
[0022] In one embodiment, the light guiding device is in particular made of a translucent material and designed as a light guiding ring, wherein the light guiding ring is assigned to the surface of the base body in the opening position, in particular is flush with the surface of the base body, and at least partially surrounds the circumference of the locking body, wherein the optical warning signal emitted by the light source into the light guiding ring is deflected towards the top surface, so that the optical warning signal is also recognizable on the top surface, in particular as a secondary warning signal, in the opening position.
[0023] A "light guide ring" is, in particular, a ring-shaped translucent optical element that completely or partially surrounds the circumference of the cladding surface, thus forming, for example, a ring-shaped or semi-ring-shaped transmission of the optical Warning signals directed towards the top are enabled.
[0024] In order to achieve an additional warning effect, an acoustic signaling device is assigned to the warning device, whereby the emission of an acoustic signal is made possible by means of the acoustic signaling device.
[0025] The “acoustic signaling device” is, for example, a loudspeaker or other sound-emitting means, which can be used to emit an “acoustic warning signal”, such as a warning tone, a beep or a sequence of tones, for example with a fixed melody.
[0026] In one embodiment, an additional light source is assigned to the warning device on the top side, wherein the additional light source is configured to emit an additional optical warning signal on the top side, in particular to emit the optical warning signal in a direction essentially orthogonal to the direction of movement.
[0027] In particular, the warning time is more than 5 seconds, more than 10 seconds, more than 20 seconds or more than 30 seconds.
[0028] In another aspect, the task is solved by a procedure for actuating a bollard according to one of the previously described implementation forms with a warning sequence to warn people within a warning time, with the following steps: - Moving the locking element along the direction of movement by means of the drive from the opening position to the warning position, - Activation of the light source, so that the optical warning signal is emitted by means of the light source of the warning device in the warning sequence over the warning time and essentially only the warning area in the warning position is visible for the warning time above the warning height above the base body and the emission of the optical warning signal, which is essentially orthogonal to the axis of movement, in the warning position with a projection of the light source above the base body above the warning height, - Moving the locking body along the direction of movement by means of the drive from the warning position to the locking position, so that the locking body is moved to the locking position up to the locking height, so that the bollard is activated with the warning sequence to warn persons within a warning time.
[0029] In one embodiment, the light source is activated before the locking element is moved into the warning position and / or before reaching the locking position, particularly in the opening position and / or after the locking element has been moved into the opening position, so that the optical warning signal is recognizable from the top by means of the light guide device, particularly before the actual warning sequence is perceptible.
[0030] The invention will be explained in more detail below using exemplary cases. These will show... Figure 1 is a schematic representation of a bollard with an arrangement according to the invention of a light source in the form of a ring-shaped LED strip , Figure 2 is an isometric view of the bollard of figure 1 , Figure 3 shows an exemplary arrangement of the bollards in an environment, namely parallel to a ground level in a parking lot, Figure 4 is a schematic sectional view of the bollards with an alternative arrangement of a light source and a light guide ring in an opening position, as well as Figure 5 is a schematic sectional view of the bollards as shown in Figure 4 in a warning position.
[0031] A bollard 101 has a base body 103, which is cylindrical. The base body 103 has a base plate 105 and a cover 107, the cover 107 being recessed into a ground level 145 such that a surface 141 of the cover 107 is arranged parallel to the ground level 145. The base plate 105 This serves to close off the base body 103 against the subsoil and, together with the base body 103, also to secure the bollard 101 in the subsoil, for example in a foundation.
[0032] Within the base body 103, a cylindrical locking element 111 is arranged, which is designed as a bollard that can be extended from the ground level 145. The locking element 111 has a top surface 143 which, in an opening position 161, is flush with the surface 141, with the locking element 111 being recessed into the base body in the locking position 161. Directly adjacent to the top surface 143, on a lateral surface 115, i.e., essentially orthogonal to the top surface 143, the locking element 111 has an LED ring 121, which is formed from an LED strip arranged in a ring shape on the lateral surface and can emit an optical warning signal 123. According to the invention, the locking element 111 is moved from the opening position 161 by a distance 183 along a movement axis 181 in the direction of a warning position 163, so that only the LED ring 121 is arranged above the surface 141 and thus above the ground level 145.The warning signal 123 is then visible with the smallest possible protrusion of the locking element 111 above the surface 141, thus significantly reducing or even preventing excessive tripping hazards or collision risks for vehicles. The top surface 143 and the surface 141 of the cover 107 are made of stainless steel and are therefore scratch-resistant and thus not very susceptible to wear. These components can also It may also be made of steel, cast steel, or another scratch-resistant material. Only after a warning time, for example 5 s or 10 s, does the locking element 111 move along a path 185 into a locking position 165, i.e., completely out of the ground level 145. An emergency access point 135 serves as access for an emergency release, depending on the drive concept (shown only as an example).
[0033] To perform the corresponding functions, the bollard 101 has an exemplary drive system 151, which includes a control board (not shown), an electric drive (not shown) for the bollard 101 to move the locking element 111, and a loudspeaker 153 for emitting an additional acoustic warning signal. It should be noted that, depending on the design of the bollard 101, a corresponding loudspeaker can also be located in the so-called "head" of the bollard 101, i.e., protected from external influences, for example, below the top surface 143 of the locking element 111. The control board controls both the drive and the functions of the LED ring 121, additional lighting, and the loudspeaker 153. Only optionally and additionally, an additional light 131 is mounted on the top 143 of the locking body 111, which can emit an additional warning signal 133.With this additional light 131, for example, an additional warning signal can be emitted before the warning signal 123 is perceptible.
[0034] In addition to the LED ring 121, a light-guiding ring 171 made of a translucent, i.e., transparent and light-conducting material, in the example shown glass, is embedded around the circumference of the locking element 111 in the cover 107. For its protection, it is slightly recessed relative to the top 143 and the surface 141. Even in the open position 161, this light-guiding ring deflects the warning signal 123 from the LED ring 121 in a direction parallel to the axis of movement 181, so that the warning signal 123 is visible even when the locking element 111 is fully recessed. For this purpose, the light from the LED ring 121 is received laterally, i.e., orthogonally to the axis of movement 181, and deflected by light guidance so that the warning signal 123 is emitted in a direction parallel to the axis of movement 181 as long as the locking element 111 is in the open position 161. Thus, the warning signal 123 can be activated even before the vehicle is moved to warning position 163 and can act as an early warning.
[0035] For example, imagine a standing person (person not shown) observing the corresponding bollard 101 in a parking space 301 with one eye 191, such that the warning signal 123 is perceptible at the latest after the bollard 101 has moved into the warning position 163, and the barrier 111 protrudes only so far above the surface of the parking space 301, namely above ground level 145, that there is no excessive tripping hazard or collision hazard for vehicles, and the bollard 101 is perceptible in good time. If the warning signal 123 is already activated when the barrier 111 is still in the open position 161, then the Persons can perceive the warning signal 123 from ground level 145 in the parking lot and, for example, be warned by a flashing yellow signal that the barrier 111 is about to be extended. It should be noted, for example, that the corresponding warning signal 123 and / or warning signal 133 can be controlled by the drive technology 151, for instance, in different colors, different frequencies, or corresponding sequences of, for example, color changes.
[0036] In an alternative configuration (see Figures 4 and 5), the locking body 111 has a light strip 221 which is arranged in an upper region of the outer surface 115, covering the entire circumference of the locking body 111, and which can emit a warning signal 231 parallel to the parking space 301 by means of LEDs. However, if the locking body 111 is still in the open position 161, the light of the warning signal is redirected by means of an overlap 281 of the light strip 221 with a light guide ring 271 along the axis of movement 181 from a direction parallel to the cover 107 to a direction essentially orthogonal to the cover 107 and appears as a pre-warning signal 235 visible from above. The light guide ring 271 can also be designed with a matte surface such that a diffuse pre-warning signal 235 is generated, which does not have a single, exclusive orientation.As soon as the barrier body 111 is moved around the path 183 into the warning position 163, a continuing overlap 283 between the light strip 221 and the light guide ring 271 ensures that the pre-warning signal 235. The warning signal 231 remains visible and is supported by the warning signal 231, which then becomes visible. As the barrier 111 continues to move along path 185 into the locking position 165, the warning signal 231 is replaced by the warning signal 231. Consequently, warning persons at any time, even in the area of the opening position 161, is only possible by using the The luminous strip 221 can serve as a light source. It should be noted that the light guide ring 271, with a suitable material selection and, for example, hardness, can also act as a dirt-repellent ring against the barrier element 111.
