OA19722A - Anti-theft security system for commercial premises, vaults and containers - Google Patents

Abstract

The present invention relates to an anti-theft security system for commercial premises, vaults and containers. Fixed inside the room to be protected, this security system is inaccessible to the tools generally used by thieves to unlock doors. Consisting mainly of a cylindrical slide (5) on which are anchored a stop (6) and an ovoid-shaped shackle (H), two bearings (3, 7), a tube (1) and a ring (0), this completely invisible security system has a hoop (10) allowing the exclusive passage of a single hand to lock and unlock it.

Description

DESCRIPTION OF THE INVENTION

The present invention relates to an anti-theft security system for commercial premises, vaults and containers.

It is well known that in order to deter, delay, and prevent thieves from breaking into premises, several devices have been created over the centuries: electrical or electronic anti-theft devices, mechanical anti-theft devices, and video surveillance anti-theft devices. Despite this, theft continues to be rampant in our countries. The theft of construction materials (reinforcing bars, cement, sheet metal, nails, paints, electrical cables, plumbing materials, etc.) as well as work equipment greatly increases the cost of construction. Similarly, burglaries in offices, stores, shops, and supermarkets are a real scourge in commerce, leading to significant loss of profitability. It therefore appears necessary to continue to seek adequate solutions to this scourge.

Electrical or electronic anti-theft devices, while preventing thieves from entering protected premises, are not within everyone's reach due to their high prices.

Video surveillance anti-theft systems are much more effective as a deterrent. They don't prevent intrusions, but they do detect, record, and signal them so the thieves can be tracked down. After a burglary, investigations and lengthy legal proceedings are required. Even if the robbers are caught, the stolen items may not be recovered.

Mechanical anti-theft devices are generally devices designed to block access, lock it, and thus prevent any intrusion into protected premises. They are very often anti-theft door blocks consisting of padlock doors and padlocks, chains and padlocks, barrel locks, interior bolts used on inhabited premises, and various locks integrated into the doors of the premises to be secured.

There are several drawbacks to existing mechanical locks. They are all visible and physically accessible to thieves. Thieves use a pair of wire cutters, a battery-powered drill, or any other suitable tool to easily unlock most of the visible mechanisms used to lock doors.

The present invention, which falls under the category of mechanical anti-theft devices, makes it possible to overcome several of these drawbacks. The entire locking system is fixed inside the premises to be protected. It is positioned so that no destructive tool can reach it. Any door closed by this means is completely locked and cannot be opened other than by the appropriate key, especially since the system that locks it is out of sight. One and only one hand passes through the circular, curved trapdoor of the hoop (10) up to the elbow level to unlock the system. There is no other way to force or break down the anti-theft system of the invention because it remains completely blind from access.

In fact, to lock the door from outside the room to be protected, one inserts one's hand through the circular trapdoor delimited by the hoop (10) placed on the metal leaf (4) - figure 1 - or (20) on the wooden leaf (14) - figure 2 -. One pushes the slider (5) - or (15) - upwards or downwards depending on whether the system is installed for upper or lower locking. The slider (5) is therefore inserted into the tube (1) sealed to the frame (2). One then turns the shackle (8) to fit it into the ring (9), and one inserts a padlock which is closed either with a key or by manual pressure. To be able to open this door, one does the reverse operation. Through the hoop (10), you insert your hand, open the padlock, remove it, turn the shackle (8) out of the panel (9), bring the slide (5) out of the tube (1), and the door is unlocked.

The entire anti-theft mechanism of the invention is physically hidden inside the protected room and inaccessible by any tools that could be used to break it down. To further conceal it from view, a hood (24) - figure 3 - covers the access hatch.

The attached drawings describe the invention. Figure 1 shows a view of the anti-theft system from the inside of the premises protected by metal door sets. Figure 2 is similar to Figure 1 for door sets made of wood and other non-metallic materials. Figure 3 shows an exterior view of the locked leaf with the coping in the upper position. Figure 4 is a view of the locking system from the outside with the coping covering the access hatch.

With reference to these drawings, and as an example of execution, the invention is an anti-theft security system for commercial premises, vaults and containers comprising:

* a cylindrical slide (5) having a section suitably chosen according to the structure of the premises to be secured. A stop (6) is fixed to this slide to prevent it from sliding out of its housing under the effect of gravity. One of the ends is cylindrical and bare, the other has a shackle (8) 5 of ovoid shape;

» two bearings (3, 7) to be welded onto the metal leaf (4) - figure 1 -, or (13, 17) to be bolted onto a wooden leaf (14) or made of any other non-metallic material - figure 2 -;

» a tube (1) to be fixed by welding on the metal frame or (11) to be screwed onto any other support;

» a ring (9) to be welded onto the metal leaf (4), or (19) to be screwed onto the leaf (14);

o a hoop (10) to be welded onto a hatch made on the leaf (4), or (20) to be screwed onto the leaf (14);

“a chaperon (24) rotating around an axis (25);

» a stop (23) allowing the hood (24) to be kept in the open position

For optimum security, the hoop trapdoor (10) must be made so that its center is located at a distance L from the center of the ring (9), L having a value between 20 and 25 cm. For access limited exclusively to one hand, the diameter 0D of the trapdoor must have a value between 7 and 10 cm. The trapdoor is made on the leaf so that its center is on the circular trajectory having radius L as defined above in relation to the center of the ring to receive the padlock. The angle between the straight line connecting the center of the ring (9) and the center of the hoop trapdoor (10) and the horizontal axis must be greater than 180° and less than 270°.

Claims (6)
