Security partition

Technical field

The technical solution concerns safety partitions, especially for banks, post offices, etc. These are partitions that have hidden additional screens during normal operation and after connection, respectively. the release of the drive is achieved by separating the space behind the partition by means of said opaque or ballistic-resistant screen.

BACKGROUND OF THE INVENTION

More designs of security partitions are currently known. These are designed either as drop plates or roller blinds, or also as plates extending upwards.

The drive mechanism can be either purely mechanical, pneumatic or electric or hydraulic.

In terms of the direction of travel of the orifice plate into the separating space are practically hardly acceptable devices where the plate or blind falls down. On the one hand there is the risk of hand injury at the level of the manipulation desk, on the other hand it is possible to mechanically block the device mechanically, eg by inserting a fixed case into the fall axis of the safety screen, etc.

In terms of propulsion, pneumatic devices, possibly hydraulic ones, are relatively expensive and often less reliable in operation than mechanical systems. Pressure reservoirs sometimes lose propellant, moving pressure seals on pneumatic or hydraulic systems are more prone to rusting, sticking or freezing far more when they are stationary for a long time, without moving relative to each other, but this is the case with safety systems that trigger only in exceptional situations and otherwise remain inactive.

Regarding mechanical systems operating with a bottom-mounted orifice, the most commonly used devices are single-spring or electromechanical drive and direct transmission. There is a common disadvantage that the device does not work fast enough and even the forces and speeds during the action itself are unsatisfactory.

For example, a solution is known according to EP-A-0283466, in which the orifice in the form of a rolled blind is pushed upwards by the drive mounted in the lower part of the safety partition. The diaphragm mechanism appears to be simple, but when the louver diaphragm is pushed quickly, there is a great force and thus a danger of the diaphragm wedging in its guide.

A solution according to DE-A-2444459 is also known, in which a diaphragm in the form of a simple plate suspended on chains directly driven by a motor extends from below. The drive constructed in this way, also with regard to the necessary acceleration of the connected counterweight, will achieve a relatively long shutter closing time or require an extremely powerful motor. Moreover, the arrangement with only one plate does not reach in a practical design and without others

Adjusting the final bulkhead height greater than approx. 2 m, while the safety requirements indicate the need to have a higher barrier.

The essence of the technical solution

The disadvantages of known systems, in particular the complexity of the mechanism, the susceptibility to failure, the low ejection speed and the low final height of the screened baffle, are solved to a large extent by the device according to the present invention. it is suspended on a lower rope system comprising a winch and lower ropes which are always fixed, one end to the main board and the other end to the winch.

The lower ropes may advantageously be guided from the winch to the main plate via at least the upper fixed pulleys mounted on the sides of the safety partition. The winch is preferably provided with a spring motor. It is also advantageous to place the winch in the vertical transverse axial plane of the safety barrier. The lower ropes may preferably be guided over the lower pulley or pulleys, which in addition may be adjustable in the partition frame. It is also advantageous if at least one additional board is mounted vertically on the main plate, which is suspended on an upper rope system consisting of upper ropes fixed at one end to an anchorage point on the safety partition frame and on each side leading to the auxiliary plate via a movable roller mounted on the main plate. Advantageously, the additional plate may be offset from the bulkhead protected zone relative to the main plate. It is also advantageous if the main plate and / or the auxiliary plate have an upper edge at or below the height of the manipulator, but not more than 30 cm. More preferably, the reduction is in the range of 3 to 30 cm. Finally, it may be advantageous to design the manipulation counter as a hinged outwardly from the partition protected by the partition.

Overview of the drawings

The present technical solution is explained in more detail with the help of the attached drawing, in which Fig. 1 shows the suspension and the drive of the safety curtain in axonometric view, in Fig. 2 the detail of the manipulation desk in partially opened position.

Example of technical solution

An exemplary security partition is based on a conventional partition such as is used in banks or post offices for customer contact. The partition has a raised frame 11 adapted for lateral sliding of the main plate 1 and the auxiliary plate 6. The main plate 1 is suspended on the lower ropes 3, guided over the upper fixed rollers 5 and through the lower rollers 4 to the winch 2. Said rollers 4,5a winch 2 are mounted in the frame 11 of the device. The winch 2 is here driven by a schematically indicated motor 13, designed as a spring motor. The additional plate 6 is suspended on the upper ropes 2, guided from the additional plate 6 via the movable rollers 9, mounted on the main plate 1, to the anchoring points 8 on the frame 11 of the device. In the rest position, the two plates 1, 6 are hung below the level of the handling console 10. The handling console 10 is attached to the frame 11 via a pivot hinge 12 located outside the protected area so that the handling console 10 is tilted out of the protected area.

-2GB 4528 Ul

The function of the device is as follows. If necessary, usually in danger of attack, the spring mechanism 13 is unlocked by the trigger mechanism and the winch 2 winds up the lower ropes 3 quickly, which lift the main plate 1 via the lower pulleys 4 and the upper fixed pulleys 5. 6, wherein the drive function here is the movable pulleys 9 lifted by the main plate 1. At the beginning of the movement, in this case the two plates 1, 6 move freely below the level of the manipulator 10 over a path of several cm. counter 10 and it folds outwards from the protected area. This achieves multiple effects simultaneously. On the one hand, the fast-moving auxiliary plate 6, which extends at twice the speed against the plate 1, suddenly tilts the manipulation console 10, causing a strong moment of surprise to the attacker. Further, when the counter 10 on the manipulating hand based offensive _t k are terms of security desired manner thrown out of the zone plate £, 6. Finally, if an attacker is trying random or block plates 1 and 6 deposited on the baggage handling counter 10, this is also thrown out. The main board 1 and the auxiliary board 6 then extend behind each other, separating the protected space from the attacker.

At the height of the manipulation desk 10 100 cm above the ground and at the height of boards 1, 6 only 85 cm, the total screening height of 260 cm is achieved even with the boards overlapping 2x by 5 cm. This is the degree that safety regulations consider sufficient. It is possible to achieve a screen height of at least 250 cm even with one extending panel, but this means a higher level of the panel handling desk and, as a rule, also a recessed panel in the rest position below the floor level. Therefore, two- or three-plate designs appear to be most preferred. When using the second add-on plate, it is hinged relative to the first add-on plate 6 in an analogous manner as before, the first add-on plate 6 has been suspended from the main plate 1.

The trigger mechanism is electromagnetic with a back-up power supply. Only mechanical starting can be used, but automation or remote control of the starter is virtually eliminated.

The plates 1, 6 may be either opaque material, where the psychological effect is predominantly achieved, or formed from ballistic resistant material, and then the degree of protection is indeed high.
