Abstract

PCT No. PCT/DE87/00448 Sec. 371 Date Dec. 19, 1988 Sec. 102(e) Date Dec. 19, 1988 PCT Filed Oct. 2, 1987 PCT Pub. No. WO88/08056 PCT Pub. Date Oct. 20, 1988.A barrier post (1) for closing a variety of access paths as well as parking lots and parking spaces in particularly easy to use and entails no risk to the user, for example by the presence of clamping points, because the swivel hinge (4) is divided into a lower and an upper hinge (6, 7). The lower hinge (6) constitutes the link between the base (13) and the displacement shaft (11) and then only after that with the tube (5) whereas the upper hinge (7) is the link between base (3) and tube (5). The displacement shaft (11) is connected, either directly through its movement nut (15) or indirectly through a guide (8), a sliding guide (9) and movement unit (15), with the tube (5) and raises or lowers the tube by appropriate rotation. This is achieved by means of a motor (13) with drive (12) accommodated in the tube (5), but which the movement nut (15) together with the whole tube (15) is pivoted upwards or downwards, depending on the direction of rotation. By fixing a spring (22) to the movement nut (15), the vertical forces are absorbed, which makes simultaneous reduction of the driving forces possible. Unintentional raising of the barrier post (1) when a vehicle (60) is parked above it is effectively prevented because the receiver (57) is blocks by the parked vehicle. The receiver (57) is reactivated, the motor switched on and the barrier past (1) pivoted upwards only when the vehicle has left its parking place.

Description

The invention relates to a barrier post for driveways, parking lots and parking boxes with a base fixed in particular on the road and the pivotable tube about a swivel from the horizontal to the vertical and vice versa, the motor and transmission housed in the tube and optionally switchable via a portable transmitter and also in the tube arranged receiver or control part.

Barriers or gates are known for closing off parking spaces, driveways and access routes, which are equipped with appropriate drives and can in some cases also be operated by remote control. These barriers have a fixed, mostly cast-iron base, the upper end of which is designed as a kind of spherical head, around which a correspondingly designed barrier can be pivoted by 90 ° or approximately 90 °. Such barriers or locking devices are known from DE-PS 1960669.0. A basically the same locking device can be found in DE-PS 2712546.8, in which, however, the graphic representation of the fixed, cast iron post has been dispensed with. Here, too, the actual barrier can be pivoted about a joint arranged on the tip of this post, whereby a locking device ensures that it can also be operated by hand in a simple manner. Also known are the entry and exit barriers, simple posts made of round material or square, which are designed to be foldable in order to release the entry or entrance if necessary by folding. The post is usually folded over by hand, for which the driver must first leave his vehicle. This is complex and disadvantageous, especially in bad weather. After all, such a parking vehicle is often a very unpleasant traffic obstruction. In addition, it is also necessary to lock the post to prevent unauthorized persons from killing the post for transit. Finally, a bollard is also known (DE-OS 3514626.5), which can be pivoted about a horizontally extending joint arranged just above the roadway. The motor and gearbox required for the swiveling process are housed in the swiveling part of the post, ie the tube, which has considerable maintenance advantages and which, in particular, enables the arrangement of such bollards in parking garages on the carriageway, since then the overall height of the post or its base can be considerably limited and preparatory work in or on the floor of the parking garage is not necessary at all. The motor can be assigned a control part which is designed to be remotely controllable, so that the driver can flip the post out of the car or also stand it up without having to leave the car. A disadvantage of these known bollards is that there are clamping points in the area of the joint, which represent a danger point in particular when handled carelessly, but also during assembly and disassembly. Another disadvantage is that considerable forces have to be applied for erecting or lowering, but above all for erecting, with the known device using a rope which also has to be deflected. The mechanical effort is therefore relatively large. In known swing gates or doors (DE-A-1580047, FR-A-2312634, DE-A-3141701), the door pivots about a hinge and an actuating spindle about another hinge which is arranged at a distance from it. In addition to the risk of injury due to the open arrangement of the individual parts, the known swivel devices are very large and are therefore not suitable for use in the narrow space of a vertically arranged bollard.

The invention has for its object to provide a locking posts avoiding the usual dimensions and safe to operate barrier posts.

The object is achieved in that a motor-driven movement spindle is arranged in the pivotable tube, the outer end of which is displaceable in the longitudinal direction on the tube sleeve and the other end via the motor in the base at a joint arranged parallel to the swivel joint is mounted, which is positioned laterally and vertically offset from the swivel joint and that the pipe sleeve is articulated with its lower end to a transmission part which is in turn mounted at its other end in the joint.

With such a barrier post there are no more clamping points, since the individual parts are pushed or pushed one over the other so that the risk of injury is excluded. Such a barrier post is advantageously safe to operate and requires little energy, because the drive spindle which can be set in rotation and the nut which can be displaced thereon create a very simple drive system. The movement spindle is driven or rotated by the motor via the gear, whereby the nut moves up or down on the movement spindle, depending on the direction of rotation, whereby the pipe is erected or lowered. The nut can either be held so that the movement spindle moves up and down in it or vice versa, depending on how the pipe sleeve is connected to the motor in the pipe. Due to the relatively low drive forces to be applied, all parts can easily be accommodated in the tube, so that they are protected and arranged in a space-saving manner and are easily accessible. The drive or motor are assigned receivers or transmitters and control units, via which the remote control can be implemented in a very simple manner.

After an expedient training of the invention provided that the movement spindle is articulated on the base with a pistol grip-like attachment on the joint. In this case, the movement spindle can expediently be held tightly against the tube wall via the attachment during the pivoting process. The lower edge of the extension thus simultaneously forms the extension of the tube wall or the outer wall when the post is upright. During the pivoting process, the approach emerges somewhat from the line of the tube wall, but without problems, since the tube wall comes close to the approach, which is designed to be curved.

In order to be able to effectively set the barrier post on the one hand, but on the other hand can be flipped over if necessary, for example to make room for the fire brigade, it is provided that the tube has a tongue which extends into the region of the base and between the two joints and has a bore , in the upright position of the tube with a hole in the base for rotation and that a cylinder lock can be inserted into both holes. The cylinder lock is fixed in the outer wall or in the base, so that the tongue can be released by removing or opening the cylinder lock, with the pivoting process pushing down the post or the tube is possible, albeit against the force of itself rotating spindle.

Safe guidance is ensured if the movement spindle is rotatably guided in a nut which is connected to the pipe socket via releasable pins and the pins are displaceable in elongated holes of the pipe running parallel to the pipe longitudinal axis. The pipe sleeve can be pushed back and forth on the pipe without snagging, with perfect transmission of force from the nut via the pins to the pipe sleeve and the other parts of the guide. Since the pins are detachable, it is also possible remove them and then fold the barrier post by hand, which is particularly necessary where there must always be safe access for the fire brigade and the police. In addition, it is therefore provided that the pins have a thread and can be fixed in the nut and releasable via a triangular edge assigned to the free end. Such triangles are common with the fire brigade and with the police, so that they can pass through such a passage at any time with their existing keys. Where the authorities must have access, for example at conventional parking lots or in parking garages, the detachability of the pins can be dispensed with.

In order to compensate for or even to compensate for the moments that occur in particular when the motor starts up, it is provided according to an expedient embodiment of the invention that a compression spring is arranged between the nut and the motor. This compression spring is compressed by the nut when the tube is lowered, the forces required for this being applied in part solely by the weight of the tube. When the tube is moved upwards, on the other hand, the spring forces act so that they move the nut forward on the movement spindle or support the motor with a gear. The compression spring expediently has a spring characteristic or a spring force, which ensures an approximately equalization of the erecting forces. The penetration of moisture into the moving parts is simply prevented by appropriately arranged seals.

An unintended erection of the bollard under a parked vehicle is prevented by an appropriate, assembly and maintenance-friendly design of the bollard by placing the receiver assigned to the motor in the head of the pipe, which is caused by a vehicle parked in the parking lot can be blocked, preferably by a correspondent arranged in the vehicle. This design is easy to install because the parts that may need maintenance, including the receiving device and locking device, are now housed in the bollard itself, ie in the pipe. In addition, such a bollard is extremely reliable because it only requires a small floor height, so that damage to the underside of the vehicle in the lying state of the bollard is excluded. In addition, since the receiver assigned to the drive is designed to be lockable for the remote control and can be blocked when the barrier post is laid flat for driving over, it is absolutely ensured that the barrier post will not be raised even if the transmitter of the remote control is actuated unintentionally. Damage to the underside of the vehicle, whether unintentional or intentional, is therefore excluded in any case. Such a barrier post thus meets the relevant regulations of the road traffic regulations.

A particularly advantageous erection safeguard is that in which the receiver is assigned a microwave transmitter operating according to the Doppler effect with the associated receiver, which is caused when the Doppler effect occurs. If, on the other hand, the vehicle is not above the lying post, the Doppler effect cannot occur and the receiver remains armed so that the post can be raised as desired at any time, for example when the vehicle has left the standing area and it is now about the Secure the standing area against unused driving. For optimization, it is provided that the microwave transmitter and the associated receiver can be switched by a button that responds when it hits the road. This prevents a kind of Doppler effect from occurring due to the vehicle moving too close to the still standing bollard, which then leads to this would mean that the standing barrier post cannot be flipped over the remote control.

Another possibility of blocking the receiver is, according to the invention, to accommodate a pressure switch in one of the lanes of the carriageway, the pressure switch being connected to block the receiver. If the vehicle passes the pressure switch or stops on the pressure switch, the receiver can be effectively blocked for as long as is necessary. If the vehicle leaves the pressure switch, the receiver can be addressed again by a corresponding time delay, and the barrier post can then be safely raised again after the vehicle has left the parking lot.

For temporary blocking of the receiver, it is also possible to assign the receiver a transmitter of a label system that is switched into blocking, the label corresponding to the transmitter having an integrated metal strip being arranged on the vehicle. Security labels are tags or stickers that are used in retail, for example, to prevent shoplifting. In the case of the invention, the labels are attached under the bumper and expediently under the rear bumper and recognized by the receiver attached in the barrier post. The actual receiver of the remote control is then blocked, so that accidental lifting is reliably prevented as long as the vehicle is above it. A metal strip made of a special alloy with a particularly pronounced hysteresis curve is worked into the labels, which are brought into a magnetic field on the receiving side so modified that it can be used for a corresponding signal.

According to a further training, the receiver can be taken out of operation by the vehicle in a targeted manner which it can be blocked via an induction loop laid in the roadway and an associated control unit. The vehicle disrupts the induction loop and thus blocks the receiver.

Injuries caused by jamming or the like can also be prevented by the drive being limited to 150 N or a small force. A further securing option can be realized according to the invention in that, in addition to the joint, a vertically arranged joint is provided which has a separate swivel drive. With such a design, the barrier post is first moved from the vertical to the horizontal, in order to then be pivoted horizontally, so that it is possible after the vehicle has passed the barrier post to pivot it back and then to pivot it up, so that the vehicle is unjustified cannot be removed from his parking lot without destroying the barrier post. So a double backup is created.

In order to secure the actuation of a barrier post that can be swiveled around the double joint and to avoid incorrect information, the swivel joint is mounted in the direction of travel of the vehicle and the motor and swivel drive are activated alternately, whereby the other drive is blocked during this time, but initially the motor when the pipe is stationary is switched. Such training ensures that when a parking lot secured by bollards approaches, the drive first responds in order to bring the bollard from the vertical to the horizontal position. The swivel drive can only be switched on when the drive is switched off, or the former automatically switches the swivel drive on, so that the bollard post, which was initially turned transversely to the direction of travel, is then swiveled in the direction of travel. So he can get off the vehicle can be run over without difficulty. After the vehicle has taken up its parking space, the swivel drive is now addressed, or only it can be addressed alone, so that the horizontal bollard is first pivoted from the direction of travel into the transverse position before the drive then responds to the post or to bring the pipe into its vertical position. In this vertical position, the barrier post blocks the parking lot or the driveway, so that even an unintentional actuation of the barrier post cannot cause damage. Rather, the barrier post is brought back into the blocking position again and again so that damage to the underside of the vehicle cannot occur.

Vandalism or accidental damage to property is particularly easy to detect if the barrier post is assigned an acoustic and / or optical signal transmitter, which is coupled to sensors on the base of the tube and the motor. The sensors note every movement of the barrier post and are switched so that they immediately switch to the signal generator when the drive is stopped, ie they signal danger. Other response and blocking pulses or transmitters are also possible, for example devices which can be operated via radar, infrared, laser, ultrasound. In order to protect batteries or electrics assigned to the drive, the current required for the drive is expediently only switched on when the system responds. Otherwise, a quiescent current that is as close to zero as possible is activated, it being conceivable to feed the quiescent current in a hooked manner by suitable devices, in order to further increase the service life of the batteries required. A 5-second cycle is advantageous, but it is then necessary that the transmitter is operated for a correspondingly long time when it responds. Other energy sources in the form of solar cells can be used, the solar cells also for Switching the device can be used, for example, by the car lights.

The invention is particularly characterized in that a barrier post is created which has no clamping points, is easy to assemble and to handle. In addition, the necessary driving forces can be generated and applied in an optimal manner, with the motor, transmission, control part and the moving parts advantageously being arranged in the securing tube. This arrangement also provides maintenance and construction benefits. The necessary forces for lifting and lowering the post or the tube are optimally transmitted and largely reduced by assigning a compression spring. The erection protection according to the invention brings a further adaptation to road traffic regulations and quality requirements for the bollard. The barrier post not only complies with the general regulations, it also saves the vehicle owner the checks that are otherwise necessary after leaving the parking lot, because accidental erection or premature erection of the barrier post is absolutely impossible. Such a bollard can advantageously also be safely passed by low-rise vehicles. Because of its design, such a bollard is relatively simple in construction and is characterized by the flat construction already mentioned. In addition, such bollards can advantageously be applied to existing roadways, parking lots or to the floor of parking garages without additional work being necessary.

A bollard (1) in a lying position is shown in FIG. 1. This barrier post (1) lies on the carriageway (2) on which its base (3) is fixed, for example via retaining screws. It is also possible to cast in the base (3), weld it or connect it to the roadway (2) in some other way.

The barrier post (1) has, in addition to the base (3), a tube (5) connected to the base (3) via an articulated arrangement (4). This tube (5) is brought around the hinge arrangement (4) from the horizontal to the vertical, as can be seen in FIGS. 2 and 3.

The joint arrangement (4) in the embodiment according to FIGS. 1 and 2 consists of a joint (6) and a swivel joint (7), the joint (6) representing a connection between the base and the movement spindle, while the swivel joint (7) is the connection between base (3) and the tube (5) directly.

The embodiment shown in FIGS. 3 to 6 shows a movement spindle (11) which is fixed, while the movement nut (15) effects the raising and lowering by means of a corresponding transmission part (8). A tubular sleeve (9) is in turn movably connected to the transmission part (8), for which purpose a joint is used, which can be explained in particular with reference to FIG. 5.

Inside the tube (5) the drive with gear (12) and motor (13) is housed. This drive (12, 13) is connected via the movement spindle (11) and the nut (15) and pipe sleeve (9) and thus also to the transmission part (8), so that when the pin (10) moves upwards, the pipe sleeve is also connected (9) and ultimately the entire pipe (5) is raised. Details are referred to below. Fig. 5 shows how the pipe sleeve (9) and the transmission part (8) pivot to pull the pipe (5) and finally bring it upright.

The already mentioned movement spindle (11) is arranged inside the tube (5). This movement spindle (11) is set in rotation via the gear (12) and the motor (13) and takes the nut (15) either upwards or downwards. The wandering of the nut (15) depends on the direction of rotation of the movement spindle (11). The direction of rotation is determined by the control part (14), which control part (14) is to be equipped with remote control devices, so that remote control of the barrier (1) is possible in a simple manner.

As already mentioned, the nut (15) is equipped on both sides with pins (10, 16) which provide the connection to the pipe sleeve (9).

The pins (10 and 16) are detachably attached in the nut (15), in particular screwed via the thread (17 and 18), so that each of the two pins (10, 16) can be screwed out separately by actuating the triangle (19) . After unscrewing the pins (10, 16), the barrier post (1) can then be operated by hand, the lifting part (5) also simultaneously moving the transmission part (8) and the pipe sleeve (9) until the pipe has reached either the vertical or the horizontal.

In order to ensure a perfect drive of the movement spindle (11), it is arranged at the bottom in a bearing (20) which is fixed via holding shells (21). A compression spring (22) is also supported on these holding shells (21) or on the corresponding base, which acts as a torque support. Their spring characteristic or their force is dimensioned so that the righting moments are almost balanced. The drive is relieved in each case by this compression spring (22) and the operation of the barrier post (1) is thus considerably facilitated.

The free end (23) of the pins (10, 16) is equipped with a triangle (19), as the small drawing next to Fig. 3 shows. This makes it possible to operate the barrier post (1) by hand, which may be necessary, for example, for passageways that must be used by the fire service.

It goes without saying that the movement spindle (11) is provided with an external thread (24) and the nut (15) with a corresponding internal thread (25). Thereby it is possible to raise or lower the nut (15) in each case according to the direction of rotation of the movement spindle (11), as mentioned taking the tube (5) with it at the same time.

Fig. 4 shows the compression spring (22) in the relaxed position. Here the barrier post (1) is in the position shown in FIG. 2. When lowering the barrier post (1) or of the tube (5), the compression spring (22) is then compressed again by the nut (15) until it is in the position shown in FIG. 3. With (45) an approach is designated, which is designed like a pistol grip, forms the lower end of the movement spindle (11) and represents the connection to the joint (6).

To clarify the special design of the transmission part (8) and the pipe sleeve (9), the connection area between the base (3) and the pipe (5) is shown again enlarged in FIG. 5. Clamping points are prevented here by the fact that corresponding bevels (26, 27) are formed on the base (3) and on the tube (5), the bevel (26) additionally having a rear wall (30) which ensures that none at all Possibilities are available to create clamping points. The division (28, 29) on the base (3) and on the transmission part (8) ensure that such clamping points can not arise. In particular, the slopes (26, 27) and the division (28, 29), i.e. So all contact edges (36, 37, 38) beveled so that they cannot be pinched even when touching or holding with your fingers.

The pipe sleeve (9) is designed as a stable hollow pipe (31) in order to ensure a perfect displacement on the pipe (5) and a safe guidance and transfer of forces from the nut (15) to the pipe sleeve (9) and thus on to reach the barrier post (1). As already mentioned, this hollow tube (31) or the tube sleeve (9) is connected in an articulated manner to the transmission part (8) via the joint (32), so that an always parallel displacement of the walls of the hollow tube (31) to the walls of the tube (5) or to the tube edges (34, 35) is ensured. (33) denotes the elongated hole, the edges of which run parallel to the tube edges (34, 35).

It has already been mentioned that all the contact edges (36, 37, 38) are so beveled, specifically in the direction of the interior (39), that clamping cannot take place even when touched.

The upper edge (40) and the lower edge (41) of the pipe sleeve (9) are expediently provided with a seal (42) to prevent dirt and water from penetrating. The same is shown in FIG. 6.

FIG. 7 shows a barrier post (1) which is remotely operated by the approaching vehicle. An additional transmitter and receiver (57) of an erection protection device (58) is arranged in the barrier post (1) in the area of the head (56) and operates according to the so-called Doppler effect. Such a field can also be created by creating a radar monitoring field and an ultrasound field or a corresponding opto-electronic arrangement, which is disturbed by the vehicle being driven over, which is picked up by the receiving part and is used to switch off or block the receiver (57). This means that the receiver (57) cannot respond and switch the drive or motor (13) as long as the vehicle is above the bollard (1). If the vehicle leaves its parking space, the monitoring field is set up again undisturbed, the receiver (57) is no longer blocked, so that the transmitter assigned to the receiver can then actuate the drive or motor (13) to return the post to its vertical position bring back. The antenna (63) with the subordinate Amplifier (64) can itself be designed so that it can be addressed or switched off by assigning a button (61) to the head (56) of the barrier post (1), which only activates the antenna (63) when the barrier post (1) is flipped. This button (61) is expediently designed at the same time as a support part (65) in order to support the barrier post (1) as such on the roadway (2).

According to Fig. 8, an induction loop is placed in the ground, via which the receiver (57) is blocked when passing the vehicle (60), so that it can no longer be switched. When leaving the parking lot or the corresponding lane (2), the induction loop or cable loop (62) is passed a second time, as a result of which the receiver (57) switches or is addressed. The arrangement of such a damped induction loop (62) on which the vehicle (60) stands is indicated in FIG. 8 accordingly.

Further options for erection protection (58) can be seen in an electronic control with a stepping function, so that the direction of movement is reversed with each new pulse output. It is also possible to install a metal detector in the post, which switches the receiver when the barrier post is completely or partially covered by the vehicle (60). Finally, the transmitter can be provided with an on-off switch in order to force the user to consciously operate it. The same applies to multiple actuation of the transmitter, which, for example, provides that a transmit signal must be emitted several times, ie two or three times, within a certain time before it leads to a corresponding switching operation. Finally, the transmitter can be designed as such to be lockable or blockable, for example by assigning it to a personal ship which is removed when the vehicle leaves the vehicle or when it returns must be used. Finally, the parking space can be provided with a switch which is actuated by the weight of the vehicle and which switches the receiver off or on again when it leaves. Finally, it can be provided that the transmitter also emits a polarized light in addition to the radio signal, so that the radio signal can only become a switching signal if the control device simultaneously absorbs the polarized light. Finally, security tags can be used, similar to those used in retail stores against shoplifting. These labels are attached under the bumper of the vehicle (60) and recognized by the receiver (57) in the post base. By recognizing the receiver is turned off at the same time, these labels have a metal strip made of a special alloy, so that a corresponding response can be reserved again for the corresponding vehicle. A circuit is particularly advantageous, via which the receiver (57) must be armed each time by a transmitter. This at least prevents the post (1) from swinging up under the vehicle (60) unintentionally.

9 and 10 are intended to illustrate a further security device which also acts as an anti-theft device. For this purpose, the barrier post (1) is provided with a horizontally arranged joints (6, 7) with a second vertically arranged joint (66) in addition to the joint arrangement (4). The horizontal joints (6, 7) are, as can be seen from FIG. 10, arranged in the direction of travel of the vehicle, not shown here, while the second joint (66) is vertical, as described.

Before driving onto the roadway (2) or the parking area (67), the barrier post (1) is in the position shown in FIG. 9. Then the assigned vehicle (60) reaches the Parking lot, the remote control, ie the transmitter not shown here, actuates the drive in the barrier post (1), so that the post turns around the joint arrangement (4) or the corresponding drive shaft in the direction of the road. When the bollard (1) has reached this position, the drive is shut down and the swivel drive, which is assigned in the joint (66) or the corresponding shaft, takes effect to move the bollard (1) from the transverse direction according to FIG. 10 in to pivot the longitudinal direction. Then the vehicle (60) can take its place on the parking area (67), whereupon the barrier post (1) is pivoted back from the longitudinal direction back into the transverse direction, specifically via the swivel drive, which, after reaching the end position, that of the joint arrangement (4) or . Corresponding shaft arranged drive switches so that the bollard (1) swings back in the vertical direction. The bollard (1) is, as shown in Fig. 10, slightly offset from the center, so that it can also be driven in the transverse direction in an emergency. In particular, this ensures that the horizontal barrier post (1) always has the necessary freedom of movement when pivoting under the vehicle (6). To limit the parking area (67), stones or the like are provided on the side, which at the same time effectively prevent transverse parking.
