FR2721629A1 - Automatic telescopic post to stop access of unauthorised vehicle in protected site - Google Patents

Abstract

The automatic vehicle control post has a column (A) that moves vertically in a shaft (B) set in the ground. The column is raised and lowered by a hydraulic or pneumatic actuator (E). The column is maintained on high position by springs (F) that are compressed when the column is lowered. The actuator is remotely controlled. The springs (F) are supported at the bottom by movable plates (H) set in a transverse support (G). For emergency lowering the plates (H) are moved sideways, allowing the springs to fall to the bottom of the shaft, and the post to fall to ground level. To restore normal operation hydraulic fluid is admitted to the bottom (P) of the actuator, which lifts the assembly till the springs (I) on the movable plate force it back to the normal state of supporting the main springs.

Description

AUTOMA @ ISEE SECURITY TELESCOPIC TERMINAL
The present invention relates to a terminal bound for control @ and possibly preventing the passage of this unauthorized vehicle at 1 entrance or at the exit of protected sites.

We know different types of terminal systems meeting so-called classic requirements @ 'is wax capable of prohibiting passage on civilian sites.

These terminals are generally controlled by jacks which have the function of maintaining them @ e @ nautical position as long as the pressure of the jacks exists.

Other bollards use springs or counterweights for this anointing.

The present invention is intended to take account of the specific conditions for the protection of civilians or militaries with enhanced security.
In particular, the functions relating to the operation required for the protection of such sites are respected.

Indeed, this porch meets the following requirements: - Be in a ha @ te position without any external energy supply.

- Automatically resume this position as soon as the action
authorization is complete.

- Have an emergency terminal lowering system
- Be automatically reactivated after this function without
outside intervention.

DESCRIPTION
The terminal is composed this
The terminal itself cites' A this parallelepipedal or cylindrical terminal which can slide in the barrel (B) by means of the slides (C) and (D).

The terminal (A) is held in the nautical position by the thrust of springs (F), mechanical o @ @@ eumatic. These springs taking support on the slide @H @@@ same content in the spacer (G) fixed on the tati 3
This slider (H) is constrained in position by the spring (I) which is contained in the co @@ isseau (H) In the rest position of the slider (H) the springs (F) are in support.

The jack (E) with the orifices P, on the pusher side and T) rotated with the shooter is fixed on the one hand to the porch (A) and on the other hand to the spacer (G) itself fixed on the barrel (8 )
OPERATION The entire terminal is connected to a power source in hydraulic or pneumatic form and supplies on demand the orifides (P) and (T) of the veri @ E @@@ P, pusher (T ) shooter @@

@safety operation
In the event of imperative necessity it a @ aissement of the terminal (A) and in the event of absence of energized hydraulic cu pneumatic.

the emergency lowering of the terminal (A) is obtained by mechanical action on the slides. 1 musi remote control available to the security service
The displacement of the slide H, then freeing the passage of the springs (F) through the spacer (G).

Therefore the base of the springs (F) passes from the position (3) to the position (4) causing by the same the passage of the terminal (A) from the position @ to the position (2).

Restoring the terminal to normal service
The pressurization of the jack (E @ par @@ orifice (P) usually without pressure, causes the rise of a terminal (A) which causes in its rise the springs @ F @
The latter then resume their normal working position with the slide (H) returning to its position under the effect of the spring (I) to support the springs again.
