BARRIER FOR BOOKING A PARKING SPACE

FOR MOTOR VEHICLE

  The present invention relates to a barrier of

  reservation of a parking space for vehicles

  automobile, in particular to reserve such places

disabled people.

  Disabled parking spaces, near public buildings, car parks

  municipal or otherwise, are often, despite the signalisa-

  specific to these locations, improperly occupied by

unscrupulous people.

  It is known to forbid access to such places

  barriers These barriers use

  the energy of the electricity grid and their implementation

  the disadvantage of requiring major civil works and various connections, which limits their use in urban areas and makes them relatively expensive. To remedy these drawbacks, the patent FR 2

  639 993, filed in the name of the Applicant, describes a bar-

  which does not require any connection to an elec-

  because, on the one hand, the means of maneuvering the

  arms are powered by the battery energy of the vehicle.

  on the other hand, the locking of the arm

  the opening position of the barrier is achieved by using

  the weight of the vehicle, through an organ

  placed in the ground In this device, however, the

  the key attached to the vehicle battery, which supplies the barrier with electrical energy, may be

  tedious or difficult for persons with disabilities In addition, the device described has a relative

  complexity. The object of the invention is to provide a reservation barrier for a parking space for a motor vehicle, which is of simple design, of which

  the installation does not require any infrastructure works

  ture, does not require connection to a

  power supply network, and being easy to use

by people with disabilities.

  For this purpose, the barrier it concerns, of the type comprising an arm pivotally mounted between an open position and a horizontal closed position, means for actuating the arm from its closed position to its open position. , holding in the open position and operating from its open position to its closed position, and a mat placed on the ground, on which is intended to bear at least one of the vehicle wheels in the parking position for maintain the arm in the open position, is characterized in that it comprises a fluid compression device which, intended to provide the energy required for the drive means of the arm during the opening and closing maneuvers, is adjacent to the carpet and disposed upstream

  of the latter in the direction of entry of the vehicle into the

  parking, and is intended to support the weight of at least one wheel of the vehicle before the movement

  opening of the arm, means actuated by the

  of compression and associated with the carpet ensuring the

  the arm in the open position then its passage in the closed position, after the departure of the vehicle, and means for controlling the supply of fluid means

arm training.

  When a vehicle is in front of the reservation barrier, at least one of the front wheels thereof is supported on the fluid compression device, for storing energy that is used to drive the vehicle. arm drive during opening and closing maneuvers After controlling the opening of the arm of the barrier, for example by means of a coded switch actuated by a code keyboard or by a magnetic card, the arm opens, allowing the engagement of the vehicle on the reserved place, at least one of the wheels of the vehicle being supported on the carpet

  placed on the ground which ensures the maintenance of the barrier in posi-

  open while the vehicle is in that place. According to a characteristic of the invention, the fluid compression device comprises a base fixed to the ground, oriented transversely to the direction of passage of the vehicle and a flexible covering surface, movable vertically, and associated with elastic means the now normally separated from the base, when no

  constraint is exerted on it, this surface of recou-

  on its face facing the pedestal, bearing elongated elements oriented in the direction of the length of the pedestal, forming levers, one end of each of which

  is attached to the piston rod of a cylinder intended

  a fluid in a storage tank and the refilling of

  in a pressurized fluid tank.

  Advantageously, each cylinder actuated by the disc

  Positive compression is connected to the fluid reservoir

  under pressure by a pipe on which is mounted a

  anti-return pet allowing only the passage of fluid from the jack to the tank and the storage tank of

  fluid through a conduit on which is mounted an anti-tamper

  return allowing only the passage of fluid from the reservoir

  see to the jack, the pressure tank being connected to the storage tank by a pipe on which is mounted a calibrated valve allowing, above a predetermined pressure, the fluid passage of the tank under

pressure at the storage tank.

  It is for example possible to provide two jacks which are actuated by two levers associated with the device

compression.

  Energy is recovered from the passage of the vehicle, not only when the vehicle arrives

  in the parking place, but also when

  In addition, the pressure in the fluid reservoir under pressure is limited because, when a predetermined pressure is reached,

  a transfer of fluid is done through the

  farted pet, to the storage tank.

  According to another characteristic of the invention, the housing delimited by the base and its covering surface contains at least one leaf spring, one end of which is fixed on a band mounted longitudinally movable inside the carpet, c that is to say in the direction of passage of the vehicle, between the lower and upper walls thereof, when no vehicle is resting on the carpet, and the other

  end, housed in the housing, forms a thin surface

  upward when no action is exerted on the housing, at least one spring being provided to ensure

  When the vehicle enters the reserved place,

  each spring leaf flattens and causes the transla-

  the vehicle associated with it The vehicle rolling on the belt causes this belt to

  this displaced position, and, consequently, maintains the

  tioning of the contact associated with the control means of the fluid supply of the arm drive means. When the vehicle leaves the parking place, the leaf springs and the springs associated with them ensure the sliding of each band in the opposite direction, the aforementioned contact is then no longer actuated and allowing the closure of the arm of the barrier Preferably, the means for rotating the arm of the barrier comprise a double-acting jack, the two chambers of which can be connected by a two-way distributor to the reservoir.

  tor being associated with an electrically controlled actuator and mounted on a power supply circuit on which are disposed, on the one hand, the associated switch

  to the compression device and operable by a blade-

  or an associated body and, on the other hand, an inter-

  coded switch actuated by the user, the jack being fed in one direction of opening of the arm when the two

  switches are in the closed position.

  In addition, the free end of the drive cylinder of the arm drives, via a toggle system, a generally disk-shaped piece, pivotally mounted about its axis, and having a radial notch, for engaging a locking finger, when the barrier arm is in the closed position. Advantageously, the locking finger is disposed at the end of the rod of a single cylinder effect,

  actuated to the retracted position of the finger by fluid under pressure and to the finger-locking position by action of a spring, the disc-shaped piece having a camming zone adjacent to the

  radial check, and located in front of it during the

  pivoting the arm to its closed position.

  When the cylinder is energized in the direction of closing the arm of the barrier, the spring associated with the

  locking finger relaxes, and the locking finger

  lage leans on the edge of the room carrying the arm.

  It is guided by the cam-shaped zone until it falls into the notch of the said piece, thus ensuring a locking of the latter and the arm of the barrier.

  in the closed position This holding in the locked position is ensured without any energy consumption.

  In any case, the invention will be well understood in

  The electrical assembly is such that when the two switches 7 and 37 are closed, the cylinder 28 is supplied with hydraulic fluid so as to allow the

  pivoting arm 4 to its open position.

  As shown in FIG. 5, a single-acting jack 38 is supplied at the same time as the chamber 39 of the jack 28. This single-acting jack carries, at the end of the rod of its piston, a locking finger 40 of the arm This finger 40 is intended, in the closed position of the barrier, to enter a notch 42 of the support part 23 of the arm 24, the finger being then subjected to the action of a spring 43 The disc-shaped piece 23 has a zone 44 in the form of a cam, adjacent to the notch 42 and located in front of the latter during the pivoting of the arm towards its closed position. As shown in the drawing, and more particularly in FIGS. 2 to 4, each casing containing the compression device is equipped with a plurality of longitudinally oriented spring blades 45, one end of each of which

  is attached to a strip of synthetic material 46

  longitudinally between the base 47 of the carpet and the

  covering surface 48 thereof prolonging the sur-

  cover face 9, thanks to the mounting of spacers

  action is exerted on the carpet, maintaining the strips of synthetic material 46 in a retracted position, as shown in FIG.

  FIG. 4, corresponding to the bent position of the leaf spring 45. The switch 37 is shown diagrammatically in FIG. 4 and actuated when, under the effect of the passage of a vehicle, the leaf spring 45 flattens and causes the plastic web 46 to move in the direction of the carpet opposite to that equipped with the compression device. The carpet surface 48 is sufficiently flexible so that when a vehicle is supported by one of his wheels on the carpet 6, at least

  one of the strips 46 of synthetic material is immovable

complicated for its installation.

  It should be noted that the device has a perfect safety of use since, once in the open position, the arm 4 can not return to the closed position if there is a liquid leak on the supply circuit of the cylinder 28, since the toggle has exceeded its equilibrium point, and prevents any return of the arm in the closed position under the action of gravity alone It is also possible, in the open position to isolate the cylinder 28 of the pressure vessel 15, for example by implementing a

  drawer distributor 32 with three positions.

  It goes without saying that the invention is not limited to

  the only form of execution of this barrier described

  as an example, it encompasses all variants.
