Definitions

  • Parking space for motor vehicles is becoming increasingly scarce, not only in the metropolitan areas. Individual parking spaces or entire parking spaces reserved for certain people or groups of people are therefore increasingly being used by unauthorized persons.
  • shut-off arrangements which can only be overcome by authorized persons with their motor vehicles.
  • Barrier shut-off arrangements are known which block the access to larger parking areas and parking lots. Such shut-off arrangements for entire areas are, however, only sensible and usable where there is a specific area that can be closed off for unauthorized persons.
  • the barrier arm in particular is predestined to carry solar cells that generate electricity, which is stored in accumulators in order to supply the electrical drive unit with energy for moving the barrier arm.
  • the drive unit and accumulators are located inside the post.
  • the drive unit which contains a low-voltage DC motor, is arranged at the upper end of the post, in the vicinity of the axis passing through the post, by means of which the barrier arm is mounted in the upper region of the post.
  • This drive unit also comprises a radio receiver which is controlled by means of a handheld transmitter which the authorized person carries with him in order to activate the drive unit and to open or close the barrier arm as desired.
  • the drive unit also includes a corresponding sensor and control system in order to move backwards in order to avoid injuries or damage when the barrier arm moves, even with very low resistance, caused by objects or persons in the range of motion of the barrier arm.
  • the barrier in the form of a barrier is that the post contains important parts, such as batteries and drive units, especially in the higher areas, but these do not have to be located directly at the base of the post.
  • To assemble the barrier it is sufficient to screw the post to the base.
  • a mounting plate that is larger than the base area of the post is usually used for this.
  • a predetermined breaking point can now be provided in the lower area of the post, as close as possible to the screw connection to the floor, so that transverse forces on the posts, which usually do not occur directly above the floor but at the level of the bumper of a motor vehicle, the post as a whole, if possible without being damaged, tears off the screw connection relative to the subsurface.
  • a predetermined breaking point could be made from an annular area made of correspondingly poorly dimensioned plastic.
  • the predetermined breaking point can also be designed to be elastic, so that even before the post is finally torn off the base plate, a deflection of the post by a certain angular amount is possible without damage, and the post returns to its original position after removal of the load.
  • the post is nevertheless detached from the base plate at the predetermined breaking point, the components therein, such as batteries and drive unit, are undamaged and, if appropriate, the post itself, which is made of sheet steel, is repaired by replacing the target breakage or the wrapping of the post relatively easy.
  • the time and therefore the repair costs remain low. Since, in contrast to the foldable barrier post, a barrier-like barrier does not have to be run over by the motor vehicle, the dimensioning, in particular of the post, is not set too narrowly and in principle there can already be no damage to the underside of the motor vehicle. In addition, no excavation work is required to sink certain components into the ground even when the barrier is installed, so that the installation of such a shut-off arrangement also requires only little effort.
  • the power supply via solar cells is dimensioned so that dim, incident light is sufficient for four hours to be able to open and close the barrier arm several times. Since the energy supplied by the solar cells is limited, the force required to open and close the barrier arm must be minimized. This is done by making the barrier arm as light as possible, yet sufficiently stable, and restricting the length of the barrier arm to the absolutely necessary length in order to keep the required torque low by reducing the lever arm.
  • the closed position of the barrier arm is adjusted so that it deviates by a few degrees from the horizontal, which is perpendicular to the axis of the barrier arm. This is particularly necessary if the solar cells are mounted in the horizontal surface of the barrier arm, since this causes the rainwater, etc., to run off, for example. If the solar cells are in the horizontal surface of the barrier arm, a 1.20 to 1.50 m long barrier arm is usually complete sufficient, the horizontal surface of which is about 15 cm wide. The area available for the solar cells ensures the sufficient energy supply of a DC motor, for example, which works with 24 volts, in the drive unit.
  • the solar cells are preferably somewhat recessed in relation to the lateral upper edges of the barrier arm, on the one hand to prevent damage from above as much as possible by the protruding side edges of the barrier arm and on the other hand also to complicate their disassembly and theft by overlapping into the side area of the solar cell surface.
  • the electric drive unit can also be mechanically decoupled from the axis of the barrier arm to be driven, for example by means of a key switch, so that the barrier can also be opened manually in the event of a lack of energy. Since an access aid, such as a key for the key switch, is also required for this, the parking space cannot be occupied by unauthorized persons even if there is no energy.
  • the barrier arm itself will preferably consist of two parallel, essentially vertical sheet metal profiles which run along opposite sides of the post and through an axis which extends from one sheet metal profile to the other extends through the post, is stored in the upper region.
  • the sheet metal profiles run parallel to one another at a distance of approximately the width of the post, or approach each other somewhat more by appropriate cranking.
  • the sheet metal profiles are preferably U-profiles. Are their free legs directed outwards, so cup-shaped plastic covers are preferably attached to their outer sides, which protrude slightly beyond the edge of the solar cells to the center, which are located between the two U-profiles. These are held at a desired distance from each other by a further U-profile or a similar spacer, so that the solar cells themselves do not have to perform a mechanically load-bearing function in the barrier arm in order to exclude torsions and other loads on these solar cells as far as possible.
  • the solar cells are not installed essentially horizontally, but at an angle to the vertical surfaces of the barrier arm, in order to ensure a better angle of incidence of the incident light rays and thus a higher energy yield of the solar cells. In this case too, it should be ensured that the protruding edge of the solar cells does not protrude beyond the sheet metal parts of the barrier arm.
  • brackets can be used on their inside for attaching an antenna rod, which is used to receive the radio signals from the handheld transmitter. This has the advantage that there are no shielding metal parts between the handheld transmitter and the antenna rod located on the inside of the plastic cover, so that good reception of the radio signal is ensured without the antenna rod protruding freely and being susceptible to damage and theft.
  • foil-shaped solar cells have recently been on the market. This allows more freedom in the design of the cross section of the cabinet poor.
  • this can consist of at least one sheet metal profile on the inside, over which a plastic cover is slid, which does not have essentially vertical, if also curved, side surfaces, but rather inclined side surfaces.
  • the film-shaped solar cells can be applied and glued to the outer surfaces of these plastic covers. Removal of the plastic cover leads to the destruction of the solar cells, so that only the connection of the plastic shell with the supporting sheet metal profiles must be made sufficiently firm and secure.
  • Fig. 1 shows the assembly of the barrier barrier arrangement according to the invention within the individual parking spaces that are to be locked.
  • the barrier post is located on the same side of the edge intended for entry into the parking space.
  • a post In the direction in which the free end of the closed barrier arm points, a post must of course stand at the next parking space in order to effectively prevent the entry of unauthorized vehicles through the closed barrier arm.
  • this post will be the barrier blocking the next parking space, but if there are then unobstructed parking spaces, this can also be a normal, permanently installed post without a barrier arm.
  • a construction of the barrier arm 3 is shown in the middle parking spaces, which consists of two straight, parallel to each other at the distance of the width of the post 2 profiles between which the solar cells 4 are mounted.
  • the two profiles are connected to one another via a continuous axis 14, which runs through the post 2 and is supported therein.
  • the two profiles will usually be sheet metal profiles.
  • these sheet metal profiles 12 between the post 2 and the solar cells 4 can be cranked in order to proceed parallel to one another at a smaller distance, as in the left Parking space shown in Fig. 1.
  • Fig. 2 shows a perspective view of one of the barriers 1 of Fig. 1, consisting of the post 2 and the Barrier arm 3, which is rotatably supported by an axis 14 in the upper part of the post 2, so that it can be pivoted from an approximately vertical, open to an approximately horizontal, closed position and vice versa.
  • the barrier arm 3 In the closed position, the barrier arm 3 is not horizontal, but deviates from it by an angle 11 in order to ensure automatic cleaning of the solar cells 4 installed in the surface of the barrier arm 3 by draining off and not evaporation of the rainwater that strikes.
  • the post 2 is hollow and made of sheet steel or similar material. On one of the vertical sides, the post 2 is accessible by opening a flap 9, which is secured by a flap lock 17.
  • the drive unit 5 which includes an electric motor 18, possibly with a corresponding gear, and a controller including Corresponding sensors which immediately stop the movements of the barrier arm and at least partially reverse them if any resistance is opposed to the movement of the barrier arm 3.
  • This drive unit 5 is connected to accumulators 6, which are located below the drive unit in the post 2 and are connected to it via electrical lines.
  • a radio receiver For remote control by means of a hand transmitter, a radio receiver, not shown, is accommodated in post 2.
  • the drive unit can be decoupled from the barrier arm by means of a key switch 10, so that the latter can also be moved manually. Since the key for the key switch 10, like the hand transmitter, is only in the possession of the authorized person, the barrier 1 cannot be opened manually by an unauthorized person.
  • the post 2 is firmly connected to the ground via the base plate 16, usually screwed.
  • a predetermined breaking point 15 is provided, which first causes an elastic yield when the transverse forces act on the post and, in the event of greater load, causes the entire post 2 to be torn off from the base plate 16.
  • the post 2 itself and, above all, the components arranged inside are normally not damaged, so that the repair only consists in the insertion of a new predetermined breaking point 15.
  • This can be a frame made of plastic material.
  • FIG. 2 shows an embodiment with non-cranked sheet metal profiles 12 running at a spacing of the width of the post 2, corresponding to the middle representations of FIG. 1.
  • barrier arm 3 shows a cross section through a barrier arm 3, which essentially consists of U-profiles:
  • Two U-profiles 19 are mounted at a distance from one another with a vertical middle part and outwardly projecting free ends 22, which is secured by a further U-profile 23 as a spacer.
  • This U-section 23, which serves as a spacer, is located in the upper area of the free space between the two U-sections 19 and serves as a support surface for the mechanically unstable solar cells 4, which therefore do not protrude above the upper edges of the U-sections 19, but slightly opposite these are lowered, which protects against damage.
  • the two U-profiles 19 are also connected to one another via an axis 14 which is supported at its ends in bearing blocks 25 which are firmly connected to the profiles 19.
  • the axis 14 can be non-rotatably connected to the U-profiles 19, so that rotating the axis 14 in the post 2 is then sufficient to move the barrier arm 3.
  • Shell-shaped plastic covers 13 are placed over the free ends 22 of the U-profiles 19, which extend from one free end 22 to the other of a U-profile and have a somewhat curved outer contour.
  • the upper free end 26 of the plastic cover 13 protrudes somewhat above the U-profile 19 into the space between the two U-profiles 19, which represents additional protection and, above all, an anti-theft device for the solar cells 4.
  • FIG. 4 shows a structure similar to that of FIG. 3, but here the solar cells 4 are inclined in order to ensure a better angle of incidence for the incident light beams. Since the solar cells 4 should not protrude above the upper edge of the profiles 19 in this case as well, the profile 23 connecting the U-profiles 19 must be mounted correspondingly lower.
  • the 3 also shows on the inside of one of the plastic covers 13 a holder 21 for receiving an antenna rod 20 for the radio receiver for controlling the drive unit 5.
  • the holder 21 consists in an approximately closed eyelet with a circular inner diameter corresponding to the outer diameter of the antenna rod 20 to be inserted, so that with at least two such holders over the length of the plastic cover 13, a simple insertion of the antenna rod 20 into the holders 21 is possible. By mounting the antenna rod at this point it is ensured that between there are no shielding metal parts on the handheld transmitter and the antenna rod.
  • Fig. 5 shows another cross-sectional shape of the barrier arm 3:
  • the U-profiles 19 are directed towards one another with their free ends 22, so that this results in a box shape which is closed towards the outside and in which there is no need for plastic covers 13.
  • the two U-profiles 19 are at least fixed relative to one another by spacers 27, which are arranged between the upper free ends of the U-profiles 19 and are firmly connected to them.
  • This spacer 27 also serves as a mounting surface for the solar cells 4.
  • the solar cells 4 can be tilted in that an additional spacer block 28 is inserted between the one free end 22 of the U-profile 19 and the spacer 27, so that the Spacer 27 is given.
  • By appropriate shaping of the spacer it can be ensured that the solar cells 4 protrude under the upper free ends 22 of the U-profiles 19 and are thereby secured against disassembly.
  • Fig. 6 shows the cross section through a barrier arm 3, as it could look when using flexible, film-shaped solar cells 4.
  • the stability and torsional rigidity of the barrier arm 3 is ensured by two U-profiles 19 which are directed towards one another and connected to one another with the central region.
  • a plastic cover 13 can be inserted or pushed over such a supporting profile, the outer contour of which can be freely designed within wide limits. If, for example, U-profiles 19 with legs of unequal length are used, the shorter free ends of which are at the top and the longer free ends 22 of which are at the bottom, the plastic cover 13 can, for example, have an approximately triangular outer contour, the The side surfaces protrude at an angle to the center.
  • the solar cells 4 are glued onto these side surfaces 29, whereby an optimal angle of incidence of the sun rays is ensured with a corresponding choice of the inclined position of the side surfaces 29.
  • the plastic cover 13 can have holders 21 on the inside for receiving an antenna rod 20.
  • the individual barriers 1 can be connected to a power line network in addition to the solar cell power supply.
  • a higher installation effort is necessary.
