FR2571420A1 - SECURITY DEVICE, ESPECIALLY FOR BANK FACILITIES, OR THE LIKE - Google Patents

Abstract

1. A security device, particularly for bank counters or the like, consisting essentially of a movable armour plate (1) actuated by a pneumatic jack (2) and disposed in the window (3) under a cover (4) closing the slot through which it passes, the cover being mounted in a hinged manner, characterised in that the closing cover (4) is actuated by a driving means (5) capable of displacing heavy loads and fed in common and simultaneously with the pneumatic jack (2) actuating the armour plate (1).

Description

The present invention relates to the field of the protection of the personnel of

  banking or other bodies or enterprises, in which values or valuables are constantly being manipulated, in particular protection against armed attack, and relates to a security device for

this effect.

  At present, service persons at these counters are generally protected against armed or other attacks by means of shielding windows.

  mobile. These known counters have an opening intended

  to allow easy communication between the customer and the service person. The latter may, during an attack, trigger by means of a button, a pedal, or other means of actuation a rapid movement closing the opening by the shield, and so

  shelter from aggression.

  The closing movement of the shielding is generally ensured by a pneumatic jack allowing a very fast closing. However, the arrangement of a large weight, for example in the form of a package or an aggressor relying heavily on the upper edge of the shield or on a closing cover of its passage slot, can lead to a blockage shielding

  start and cancel any protection.

  The present invention aims to overcome these

inconvénients.-

  It has, in fact, a safety device, in particular for bank counters, or the like, consisting essentially of a movable armor plate actuated by a pneumatic jack and arranged in the window under a closure cover of its slot. passage mounted tilting manner,

  characterized in that the closure lid is action-

  born by a motor means capable of moving heavy loads and powered in common and simultaneously with the

  pneumatic cylinder for actuating the armor plate.

  The invention will be better understood thanks to the

  description below, which relates to a method of

  preferred embodiment, given by way of non-limiting example, and explained with reference to the appended diagrammatic drawings, in which: FIG. 1 is a fragmentary side elevational sectional view of a device according to the invention; FIG. 2 is a rear elevational view, on a smaller scale, of a window equipped with the device according to FIG. 1, and FIG. 3 is a side elevation and sectional view.

from the window of Figure 2.

  According to the invention, and as shown more particularly by way of example, FIG. 1 of the appended drawings, the safety device, in particular

  for bank counters, or the like, which is essential

  constituted by a movable shielding plate 1, which is actuated by a pneumatic cylinder 2 and is arranged in the aperture 3 under a cover 4 for closing its passage slot, this cover being pivotally mounted, is characterized in that said cover 4 is actuated by motor means 5 capable of moving heavy loads, this means being fed in common and simultaneously with the pneumatic actuator 2

of the armor plate 1.

  The motor means 5 is advantageously a pneumatic cylinder secured to the head of the pneumatic cylinder 2 for actuating the shielding plate 1 and slightly inclined relative to the vertical, in the direction of the displacement direction of the plate 1, so as to develop a maximum force on the underside of the cover 4 on

  most of its tipping path.

  The stroke of the pneumatic cylinder 5 is limited so that the end 6 of its piston rod

  does not enter the path of the armor plate 1.

  The extreme deployment position of the cylinder 5 is

  in this extreme position, the final tilting of the lid 4 is ensured by the upper edge of the armor plate 1 under the action of the jack 2, which then no longer undergoes a significant increase in the force to be provided, the lever arm of the point of application of the edge of the plate 1 against the underside of the cover 4 to the hinge 7 of the latter being very large compared to the resultant of

  force still applied to said cover 4.

  In order to ensure a good sliding contact between the end 6 of the piston rod of the cylinder 5 and the underside of the cover 4, said end 6 is equipped with a cap 8 of synthetic material, or other, having a low coefficient of friction. Thus, it is ensured a good sliding between the surfaces in contact, so that practically the entirety of the force of

  thrust of the jack 5 is transformed into a rocking force

  4 of the cover 4 out of the path of the plate 1 actuated by the cylinder 2 and guided in grooves 9

counter amounts.

  Thanks to the invention, it is possible to provide safety devices, in particular for bank counters, or the like, allowing quick and easy removal of the shielding plate, even when loading its exit slot or the cover covering it, by

  synchronized actuation, on the one hand, of the rocker cylinder 5

  4, and on the other hand, the jack 2 for mounting the shielding plate 1, so that, simultaneously with said tilting of the cover 4, the plate 1 rises behind this

  last and close the opening of communication of the counter.

  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, especially from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without leaving

  for all that the field of protection of the invention.
