Description

FIELD OF THE INVENTION

This invention relates generally to hardware and, in particular, to devices for locking and sealing the doors of railway cars, freight containers and vans, tank hatches, steering wheels for grain hoppers, warehouses, warehouses, shops, stalls and other objects. More specifically, the invention relates to locking and sealing devices (ZPU), in which a flexible element is used as a contactor, for example, a piece of rope (cable) equipped with a means of controlling an unauthorized opening.

State of the art

Currently, widespread use is being made of visual inspection tools for unauthorized opening of flexible locking and sealing devices, including by using the fixation of the tip in the closed state of the device with the formation of the so-called non-working back loop.

The principle is that after bringing the ZPU into a closed state (taking into account the tightening of the flexible element of the rope segment to form a minimum loop), fix the tip of the free end of the rope segment in the ZPU case in a hole specially provided for this in the case with a separate fixing mechanism. A non-working back loop allows you to provide visual control of the integrity of the ZPU attached to the guarded object (wagon, container, etc.) and prevents the possibility of unauthorized opening by pulling a piece of rope from the body, stealing the contents and closing again without noticeable signs of opening.

A flexible ZPU with a tamper evident control device is known, which is described in patent RU No. 103558 (E05B 39/03). It contains a housing and a cable segment, one end of which is rigidly fixed in the ZPU, and the free end is equipped with a rigidly fixed tip, is pulled through a passage channel made in the housing and fixed by means of a locking mechanism located in the housing. At the same time, the control tool is made in the form of a flap washer mounted in the housing in a two-stage lateral hole interacting with the surface of the annular groove made on the tip when it is pushed when an inoperative back loop is formed.

Also known ZPU with a means of control of unauthorized opening, described in patent RU No. 2396405 (E05B 39/02). It contains a housing and a cable segment, one end of which is rigidly fixed in the ZPU, and the free end is equipped with a rigidly fixed tip, is pulled through a passage channel made in the housing and fixed by means of a locking mechanism located in the housing. At the same time, a neck is made on the tip, which interacts when pushing the tip through an autonomous hole in the bottom cover in the closed state of the device with a spring clip mounted inside the metal-intensive bottom cover.

The disadvantages of both the analogue and the prototype include the need to manufacture either a new metal-intensive casing to accommodate the tab washer in its lateral part, or a metal-intensive (thick) and difficult to handle cover with the subsequent change in the design of the ZPU device.

The technical result of the proposed invention is the elimination of these shortcomings and the control of unauthorized opening of the switchgear with small changes in the design of the device, i.e. with almost 100% unification.

Disclosure of invention

Ensuring the specified technical result is achieved due to the fact that in the means of control of unauthorized opening of a flexible locking and sealing device containing a body and a piece of rope, one end of which is passive, and the second free end, equipped with a tip, is passed through the inlet and outlet of the housing and located between them the passage channel with the formation of a loop and is fixed in it when closed by means of a locking mechanism located in the housing, while the means of control unauthorized opening is made in the form of interacting with a stop on the neck of the tip after it is pushed through an autonomous hole under the tip when an inactive back loop of the clamp is formed, according to the invention, the clamp is located in a rigidly closed module cover of an autonomous module having a shell-shell and said self-contained opening for the tip and having the possibility of mounting it on the device.

And also the fact that the latch is made in the form of a petal washer, rigidly fixed together with the module cover in the shell case, which interacts in a closed state with an emphasis on the neck of the tip, while an autonomous hole is made in the module cover.

And also the fact that the latch is made in the form of a locking ring mounted in the annular groove of the casing-shell, interacting in the closed state with an emphasis on the neck of the tip, while a self-contained hole can be made either in the module cover or in the casing.

And also the fact that the stand-alone module is equipped with a bracket with a technological hole, by means of which it is mounted either on the section of the passive end of the rope segment protruding from the device casing in the upper part, or on the section protruding from the casing in the lower part, while it can be located as from the fastening side of the passive end of the rope segment, and from the inlet or outlet.

And also by the fact that the stand-alone module can be rigidly fixed to the device body either by welding, or by means of a threaded connection, or by means of glue with the possibility of pushing the tip either in a vertical plane from above or below or in a horizontal plane.

And also because the stand-alone module can be mounted on the device’s body, for example, by means of a magnet with the possibility of its removal and with the possibility of pushing the tip in any plane.

The implementation of the invention

The means for controlling the unauthorized opening of a flexible locking and sealing device includes a housing 1 and a piece of rope 2, one end of which is passive 3, and the second free end 4, equipped with a tip 5, is passed through the inlet 6 and outlet 7 of the housing opening and the passage channel 8 located between them with the formation of a loop and is fixed in it when closed by means of a locking mechanism 9, located in the housing 1. In this case, the tamper-evident control device is made in the form of interacting with Hur tip 10 on the neck 5, after pushing it through the opening 11 under the independent tip 5 of the formation broken latch feedback loop 12.

According to the invention, the latch 12 is located in the rigidly closed module cover 13 of the stand-alone module 14, having a shell-case 15 and the aforementioned stand-alone hole 11 for the tip 5 and having the possibility of mounting it on the device (either by mounting it on the passive end of a piece of rope or on the device body ; examples are given below).

Also, as an example in FIG. 3, the latch 12 is made in the form of a tab washer (i.e., a lock washer with internal petals), rigidly fixed together with the module cover 13 in the shell case 15, which interacts in a closed state with a stop 10 on the neck of the tip 5, while the stand-alone hole 11 is made in the module cover.

The latch can be made, for example, in the form of a locking ring mounted in the annular groove of the shell-shell 15 (standardized and normalized parts and assemblies), interacting in the closed state with a stop on the neck of the tip, while an autonomous hole can be made either in the module cover or in a shell case (not shown). Also, the latch can be made in the form of a plastic latch, or in the form of a capsule with a substance hardening outside the capsule when it is destroyed (not shown).

4-7, the stand-alone module 14 is equipped with a bracket 16 with a technological hole 17, by means of which it is mounted either on the section of the passive end 3 of the rope segment protruding from the device casing in the upper part, or on the section protruding from the casing in the lower part, this it can be located both on the fastening side of the passive end 3 of the rope segment (Fig.4, 6, 7), and on the side of the inlet or outlet (Fig.5), and it can be located with the cover of the module 13 as turned down, and up.

And in Fig. 7, a stand-alone module equipped with a bracket 16 with a technological hole 17 is shown not fixed at the passive end of a rope segment, i.e. mounted freely on a given section of the passive end of a piece of rope protruding from the device casing in the upper part, while it can be fixed against movement in a vertical plane, and thus, the stand-alone module 14 can be rotated in a convenient position to fix the tip in it and , therefore, allows you to place it on the front side of the case at any angle to the latter.

On Fig-12 stand-alone module 14 is shown rigidly fixed to the device by welding, either through a threaded or riveting connection, or glue with the ability to push the tip in a vertical plane from the bottom, while:

on Fig and 11, respectively, from the side of the inlet 6 and the outlet 7;

figure 9 - on the side of the fastening of the passive end of the rope;

figure 10 - from the bottom side of the device;

on Fig - on the front side of the device.

Of course, it goes without saying that the stand-alone module can be mounted on the device body by the indicated methods with the possibility of pushing the tip in the horizontal plane, as well as at any angle.

In addition, a stand-alone module can be mounted on the device’s body, for example, using a magnet in any suitable place at any angle and in any plane and, therefore, with the possibility of pushing the tip also in any plane.

In this case, the shell-shell 15 of the autonomous module can be made cylindrical, conical, trapezoidal, in the form of a parallelogram, in the form of a sphere, etc.

Information may be deposited on the enclosure, for example, a duplicate seven-digit control identification number of the device.

And also on the case-shell of the stand-alone module, a protective self-adhesive label - “ZPU - control” can be applied. On the device’s body there is a place for applying the necessary sealing information.

The device is used as follows.

When locking, the free end 4 of the rope segment 2 is sequentially passed through the holes of the eyes of the locking object, the inlet 7.

The free end 4 begins to interact with a spring-loaded locking mechanism 9, containing, for example, one ball (Fig. 1), squeezing it down along the longitudinal axis of the housing (the locking mechanism may include one or two balls or a roller or fixing elements located in the separator). In this case, the ball, dropping down, allows the passage of the length of the rope 2 through the passage channel 8 and then through the outlet 7. Then the length of the rope is manually tightened to form a loop of minimum size. With the cessation of the application of force on the segment of the rope, the spring-loaded locking mechanism 9 reliably fixes it in this position.

But since there are technological gaps between the segment of the rope 2 and the inlet 6, from the inlet side the introduction of any tool into the case is not excluded, and therefore, the contact of the instrument with the locking mechanism and the subsequent pulling of the rope in the direction opposite to theft, theft contents and re-locking. Moreover, this may be unnoticed before the arrival of the goods.

To exclude the latent criminal impact on the locking mechanism through the inlet 6 of the body (cover), the stand-alone module 14 mounted on a flexible switchgear (passive end of a piece of rope or a body) serves as an unauthorized opening control device, which operates as follows.

The tip 5 of the free end 4 of the segment of the rope after bringing the ZPU in a closed state with tightening the length of the rope to form a loop of the smallest size is introduced into the hole 11 in the modular cover 13 (Fig.3), and then pushing it further, overcoming the force of the spring tabs of the tab washer - latch 12, the conical portion of the tip 5 spreads them apart, and with further advancement, they fall into the neck of the tip, and when removed, they will interact with the stop 10 on the tip 5. Checking the reliability of the tilt fixation Chechnya is attempted manually with little effort to remove it from the shell-shell 15.

Now, for unauthorized opening of the device, the attacker must first release the tip 5, i.e. remove (pull) it from the latch 12. In this case, two options are possible: either the tip will collapse, or it will be removed from the length of the rope in the case when the force of compression on it is in the range of 1000-1500 N.

These actions will be obvious, i.e. removing the tip not without destroying the latter or removing it from the length of the rope becomes obvious - they will not be unnoticed.

At the same time, this effect is achieved in comparison with the prototype through the addition of only one element: an autonomous module. At the same time, the design of the device does not change (the design of any device, for example, for a rope with a diameter of 5.0 mm or less, is also practically unchanged. Almost 100% unification of the body, locking mechanism and other parts of the basic device is ensured, thereby time and costs for the preparation of production will be minimal.

Comparison of the claimed technical solution with the prior art known from the scientific, technical and patent documentation on the priority date in the main and related sections did not reveal a tool that has features identical to all the features contained in the claims proposed by the applicant, i.e. the set of essential features of the claimed solution was not previously known and is not identical to any known technical solutions. Therefore, it meets the condition of patentability “novelty” and “technical level”

The claimed technical solution is industrially applicable, since it can be manufactured under production conditions of any scale. Those. it is workable, feasible and reproducible, and the distinguishing features of the solution allow you to get a given technical result.

Those skilled in the art will appreciate that modifications may be made to the disclosed embodiment without departing from the scope of the invention as defined in the appended claims. For example, to attach a stand-alone module to a protected object.

The disclosed described embodiment is provided by way of illustration and not limitation.

The authorized opening of the device is carried out by biting a piece of rope with a special tool. Before authorized opening of the device, it is necessary to visually check the tip: its mounting reliability in the stand-alone module and integrity.

Thus, the invention allows to increase the degree of control and protection of the ZPU from its unauthorized opening.
