Description

I

  The present invention relates to a device for the controlled reservation of a garage space or a pass.

  wise for a vehicle comprising a box fixed to the ground carrying a movable arm, driven by a motor, housed in the box and controlled by a sensor according to the presence or the vicinity of an authorized vehicle, the arm being movable

  between a retracted, lowered position, releasing the em-

  placement or passage and an active position, raised, in-

  preventing access to the site or passage.

  There are already parking space reservation devices such as that described in document WO 92 06 247. However, these known devices have the drawback of being relatively fragile and unprotected against forcing attempts. If a vehicle

  force the moving part, in the raised position, the forces are more or less transmitted to the mechanics, inside the device.

  positive, and make it unusable. The object of the present invention is to remedy

  these drawbacks and proposes to create a device for

  servicing of a site or access or passage, which can be subjected to a violent effort without risking being damaged by the attempted violation and without requiring the intervention of a specialist to replace a part which

would be destroyed.

  To this end, the invention relates to a reservation device of the type defined above, characterized in that

  that the link connecting the motor to the axis carrying the arm

take:

  - an axis connected to the movable arm comprising a glass housing

  rusting associated with its active position, - a lock carried by a lever pressing against the contour of the axis on the trajectory of the locking housing

  to enter this housing when the axis comes in

  active position, - a driving pinion, carried in rotation by the motor outlet, having

  * a non-toothed sector corresponding to the lift stroke

  lock, * a cam to cooperate with the lock lever and lift it to disengage the lock from its housing on the shaft,

  - a driven pinion, mounted free in rotation on the axis and eng-

  with the driving pinion connected to the axis by an indexed, disengageable, threshold link, - the non-toothed sector of the driving pinion being opposite the driven pinion when the axis is in the active position, the latch

  being engaged in its housing in the axis.

  This device, although resistant to very large efforts, nevertheless gives way in the event of excessive efforts to avoid destruction of the mechanics and the engine. This system is protected in two ways, on the one hand against

  the antagonistic efforts, generally accidental or not indirect

  during operation (raising or lowering

  ment of the arch) and, on the other hand, against the efforts

  break-in exerted on the roll bar in static position

  vee. To reset the disengaged system at its

  link with the engine, just leave the engine running-

  ner or operate it again to reset the link

its disengageable at the threshold.

  More specifically, the disengageable link to

  threshold connecting the pinion driven to the axis carrying the arm

  takes: - an imprint ring, integral in rotation with the axis but free to slide thereon, this ring having imprints in its face turned towards the driven pinion,

  - the driven pinion comprising fingers for housing

  removable in the imprints of the ring, the driven pinion being integral in translation with the axis,

  - a helical spring fitted on the axis and one end of which

  mite rests on the axis, pushing by its other end the fingerprint ring against the pinion driven with force

  defining the declutching threshold, allowing the

  health of the force created by the torque applied by the arm to the axis to release the fingers of the driven pinion, by effect of

  ramp against coil spring thrust.

  This link constituting a first torque limiter protects the mechanism and the motor against false

  maneuvers during movement of the roll bar, both at the

  cente than the climb. Such a situation arises if a vehicle tries to pass too much on the rollbar not completely

  lowered or on the roll bar during recovery.

  According to another advantageous characteristic, the axis locking housing is produced in a ring

  secured to the axle and one end of the lever carrying the

  rou is applied elastically on the ring to come in

  the housing when it arrives in the appropriate position

  requested, this lever being elastically connected by its other ex-

  end to a link itself carried by the axis.

  This locking means offers the advantage of a relatively large surface on which the lock slides to the active position. In addition, this avoids having to

  achieve a relatively large dimension in the axis

  bearing which would considerably weaken the axis.

  According to another characteristic, the end of the lever, connected to the link, carries an elastic block placed

in a housing of the housing.

  According to another characteristic, the lever and the latch as well as the ring are split in part and

on the other side of the link on the axis.

  This duplication allows for a symmetrical mounting.

  stick transmitting balanced forces very effectively

towards the link.

  According to another characteristic, the device comprises a torsion spring fitted on the axis with a fixed end relative to the housing, the other end of the spring being attached to a point on the axis to exert a restoring torque on the axis, the housing being provided with a fixed stop and the axis, with a peripheral stop coming elastically

  against the fixed stop to define the position of rotation ac-

tive of the axis.

  This reminder keeps the arm still in

the same position.

  For added security, the arm is

  connected to the axis by an indexed link, disengageable at the threshold.

  The reservation device is preferably autonomous and for this purpose comprises a battery and a photovoltaic cell for charging the battery supplying the circuit.

  electronic engine control and a receiving sensor

before the vehicle signals.

  Additionally, the device includes a noise generator for emitting noise in the event of an operation.

  fraudulent or attempted violation of the device.

  Finally, it is interesting to reinforce the dis-

  positive and make the whole balanced, that the arm is in the form of a hoop with two radial branches each fixed to a

  end of the shaft exiting on both sides of the housing.

  The present invention will be described below from

  in more detail using the accompanying drawings in the-

  which: - Figure 1 is an overall view showing the installation of a reservation device applied to parking spaces according to the invention, - Figure 2 is a partial sectional view of the device along the section line II-II of Figure 3,

  According to FIG. 1, the invention relates to a device

  controlled reservation of a parking space or an access or a passage. This device 1 consists of a housing 2 fixed to the ground at the location 3 to be protected. Box 2

  carries an arm constituted in the present example by an arch 4 with two branches 41, 42. These two branches are connected by one end to an axis controlling the movement of the arch.

  This connection is made by a disengageable indexed means with threshold as will be described later. The arm or the roll bar can be put in a lowered, retracted position, in which it practically surrounds the housing, coming flat on the ground and an active position, raised and locked, in

  which it prohibits access or passage as is re-

  presented schematically at the different locations.

  The device will be described in more detail.

cut below.

  The overall section view according to FIG. 1 shows

  be the box 2 fitted with the hoop 4 carried by an axis 5.

  Axis 5 mounted in bearings 6, 7, or direct-

  ment in the housing 2, projects on each side of the bearings to receive the end of each of the two branches 41, 42 of the arch 4. In the case of an arm with a single branch, the

  fixing is done only at one end.

  The axis 5 is controlled in rotation by an electric motor or geared motor 8, supplied on command from

  of a battery 9. This battery 9 is supplied by a cell

  the photovoltaic cell 10 occupying the top of the housing 2. This cell is shown in broken lines in FIG. 2 and

in section in Figure 3.

  An electronic circuit 11 manages the operation

  of the device as will be seen later.

  According to Figure 4, the motor 8 is connected to the axis 5 to control the movement of the arm or the hoop by

  through a pinion leading 12 out of the motoreduc-

  tor 8. This driving pinion 12 meshes with a driven pinion 13

  carried, free to rotate, by axis 5. The driven pinion 13 coo-

  father himself with a fingerprint ring 14, integral in rotation with the axis. This fingerprint ring 14 can slide longitudinally with respect to the axis 5 thanks to a lug 15 or key housed in an axial groove 141 of the ring 14 allowing this longitudinal movement. The fingerprint ring

  has indentations 142 in its face turned towards the pi-

  driven gnon 13 and the latter comprises lugs 132 intended to be housed in the cavities 142. The driven pinion 13 is blocked in translation on the axis 5 since it comes to bear against means which will be described later. The impression ring 14 is pressed against the driven pinion 13 by a

  helical spring 16 fitted on axis 5 and one end of which

  mite 161 is supported on a ring 17 integral in transla-

  tion of the axis, the other end 162 pressing against the

  fingerprint ring 14. The force developed by the spring de-

  ends, with the geometry of the lugs 132 of the driven pinion 13 and of the imprints 142 of the ring 14, the declutching or opening threshold of the connection in rotation between the driven pinion 13 and the imprint ring 14; at this time the lug (s) 132 are released from the imprints 142 by a ramp effect, in

  pushing the ring 14 against the force of the spring 16.

  According to FIG. 5, the driving pinion 12 has at its periphery a non-toothed sector 121 so as not to transmit a rotational movement of the driving pinion 12 towards

  the driven pinion 13. The axis 5 also carries a torsion spring

  sion 18, one end 181 of which rotates on the

  housing while the other end 182 is hung soli-

  dary to a pin 19 planted in the axis 5. This torsion spring 18 tends to return in rotation the axis 5 in

  a recall position defined by the cooperation of a

  pile 20 placed in the axis 5 and coming against an elastic stop-

  tick 21, fixed, fixed to the housing 2 (fig. 7).

  Thus, the torsion spring 18 always tends to rappe-

  ler, by rotation, the axis 5 so that its pin 20 is

resting against the stop 21.

  According to FIGS. 6A, 6B, the link connecting the motor 8 to the axis 5 is completed by a lock 22 carried by

  a lever 23. The axis or more precisely a ring 24 solid

  axis 5 has a housing 241 (fig. 6B) in a

  position defined relative to the active position of the axis.

  The lock 22 is placed relative to the axis 5 so that when

  the axis arrives in the active position, i.e. in the re-

  lifting of the arm or the roll bar 4, the latch 22 penetrates radially

  in the housing 241 of the ring 24 and blocks the rotation

  tion of the ring and consequently the rotation of axis 5 and that

  arm or hoop 4 (fig. 6A). This lever 23 is sensitive

  tangentially tangent to the periphery of the ring 24 and during the rotation of the axis 5, before the latch 22 enters its housing 241 of the ring, the lever 23 presses, by its weight, on the latch 22, against the peripheral surface of

this locking ring 24.

  The other end 231 of the latch lever is re-

  linked via a pin 25 and an elastic sleeve

  that 26 at one end 271 of a link 27 of which the other

  end 272 is mounted to rotate freely on axis 5.

  The end 271 of the link 27, connected to the end 231

  of the lever 23, carries two damping plates 28, plate

  cées in a housing 29 of the housing 2 to thereby form

support points.

  In fact, according to the embodiment shown (fig. 2, 4), the locking ring is split, on either side of the bearing of the rod on the axis; the lock

  is also split on both sides of the link.

  The ends of the two levers are connected by an axis which carries the elastic sleeve forming a damping block and this sleeve is itself placed in a cylindrical cavity at the end of the link. Finally, the assembly is placed, as indicated above, in the housing 29 of the housing 2 of the

  device 1. For reasons of simplification, the different

  split parts annuities have the same references as

those already described.

  The mounting and operation of the bolt, which appear clearly in FIGS. 4-6B, are very effective in absorbing a large opposing torque, induced by the arm 41, 42 in the axis 5 and opposing the movement of the arch. This effort, which can be very violent if it is exerted by a vehicle seeking to push the hoop 4, nevertheless only results in a very long longitudinal component.

  weak, induced by latch 22 in the longitudinal direction

  nale of the lever 23 which carries it. If the effort that has to be trans-

  put the axis becomes too important and exceeds the threshold defined by the spring 16 of the fingerprint ring 14, the connection at the level of this fingerprint ring opens relative to the driven pinion 13 and the device picks up without this excessive torque does not risk being transmitted to the motor 8. The rotation of the driving pinion 12 continues so that the driving pinion 12 presents to the driven pinion 13 its sector not

  toothed 121. The driven pinion 13 cannot therefore transmit any

  full reverse to the driving gear 12 when the motor 8 is stopped

  tee and that a torque is exerted on the hoop 4 and by

  through the axis 5, on the driven pinion 13.

  Depending on the moment at which the obstacle to the movement of the roll bar arises, the motor continues to drive the

driving gear 12.

  For the controlled unlocking of the roll bar 4, the driving pinion 12 carries a finger-shaped cam 123 which

  raises the lever 23 of the latch 22 and releases it.

  In fact, there are two levers 23 symmetrical with respect to the link 27 and connected by the latch 22; these two levers 23 are also secured in rotation by

  axis 25 which brings them together, so that the lifting movement

  ment exerted by the cam 123 of the driving pinion 12 is exerted on the two levers 23 releasing the bolt 22 from its housing

  241 and releasing the locking rings 24.

  Then the toothed sector 122 of the pinion leading 12 ar-

  shore in mesh with the teeth of the driven pinion 13 and can

thus lower the roll bar 4.

  It should be noted that in order not to complicate the device, the rest position or lowered position is not locked because, in this position, the arch 4 does not

  risk of being subjected to a violent effort to force the posi-

  tion. When the arch 4 has undergone a force having produced the disengagement of the connection between the finger ring 14 and

  the driven pinion 13, the rotation of the motor 8 and of the pinion

  nant 12 leads the driven pinion 13 in coincidence with the em-

  stamps 142 of ring 24 and from this moment the

connection is again engaged.

  Figures 2, 7 show the device for pro-

  tection which is implemented when the arch 4 is raised, in static position, that is to say not in movement, driven

  by the engine. According to this protection device, the

  mites 411, 421 of the branches 41, 42 of the arch 4 (or the end of the arm) are connected to the respective end of

  axis 5 by another indexed and disengageable link at the threshold.

  The structure of this link is quite similar to that of

  above: the axis 5 carries an indexed washer 30, and the end 411 of the branch 41 is rotatably fitted on the end of the axis 5 by its sleeve-shaped end provided with fingers 31 intended for cooperate with the indexing orifices 301 of the washer 30. These two parts 30, 411

  are pushed against each other by a stack of washers-

  the Belleville 32 retained on axis 5, in a housing of

the end of the arm.

  This device is released when a significant effort

  as much is applied to the roll bar in the raised position. Whatever the direction of the force exerted on the arch, as soon as the threshold is exceeded, the finger or fingers 31 are released from the indexing orifice (s) 301 of the washer 30. Then the finger slides on the washer with a significant resistant force linked to the force developed by the Belleville washers 32. As a result the arch remains in the position in which it is

  strength. When this external effort disappears,

  manually move the headband into position to engage the finger

31 in the indexing hole 301.

  The device according to the invention also includes a buzzer 33 (fig. 2) intended to emit a noise during

  that the device is forced or for example when an unauthorized vehicle gets too close to the device. Indeed, the device advantageously comprises a sensor and the vehicle or vehicles authorized to occupy the site or to cross the passage blocked by the device are equipped with a coded signal transmitter. These coded signals, received by the device,

  are identified by the electronic circuit and in the event of

  authorized vehicles, the electronic circuit then controls the

device for lowering the arm.

  Conversely, when the vehicle leaves the location, for example above the device, when

  moves away from the location, a signal is transmitted to the device and the printed circuit then controls the lifting5 of the roll bar.

  Advantageously, the arm or the hoop 4 according to

  the invention (fig. 2) consists of a metallic reinforcement

  than 43 wrapped in a plastic sheath 44.

  The device is fixed to the ground by screws at the

  placements 35, 36, 37, 38; the screws are put in place beforehand, then the housing is engaged on the screws and the

  final tion is made at the fixing points 37, 38 which are accessible from above through the housing before installation of the solar cell 10; this is slid into 15 lateral grooves of the housing and the assembly is blocked by a rod 39 clipped into the edge of the housing 2

(fig. 3).
