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, helper wheels for grain carriers, warehouses, warehouses, shops, stalls and other objects.

More specifically, the invention relates to flexible locking and sealing devices (ZPU), in which a flexible element is used as a contactor, for example, a piece of rope (steel cable).

State of the art

A flexible locking and sealing device (2141557, E05B 39/02) is known, comprising a body and a piece of rope, one end of which is passive and a second free end made pointed to facilitate transmission through the inlet and outlet openings of the body and the passage channel located between them , with the formation of a loop is fixed in it when closed by a locking mechanism located in the housing. In this case, the sharpening is achieved mainly by soldering.

A flexible locking and sealing device (2145013, F16G 11/04) is also known, comprising a body and a piece of rope, one end of which is passive, and the second free end, also made pointed by soldering to facilitate transmission through the inlet and outlet openings of the housing and located between them the passage channel, with the formation of a loop, is fixed in it when closed by means of a locking mechanism located in the housing.

Moreover, the known solution may have a cap that is rigidly fixed to the free end, mainly by tightly crimping it flush with the outer surface of the cable segment.

The disadvantages of the known solutions include the need to solder in a certain way the end of the cable segment for a relatively large length - about 10-12 mm. The soldering operation itself is time-consuming, and the material used for soldering - tin, is an expensive material. Reducing the length of the end of the segment to be soldered means saving both expensive material and saving time. In addition, the free end of the cable segment treated in this way acquires excessive rigidity, as a result of which when it is locked when inserted into the inlet with instantaneous force at the moment of contact with the surface of the inlet, sliding along the upper surface of the inlet or “plugging” into him.

The technical result of the invention is to remedy these disadvantages.

As a brief summary of the essence of the invention, it should be noted that in order to achieve the indicated technical result, in the known technical solutions for processing the free end of the rope segment, nothing changes, but is only supplemented by an element that significantly affects the characteristics of the ZPU, in particular, they become highly available the information content of the unauthorized opening of the device in its closed state (if necessary, at the request of the customer), by ensuring -visual integrity is adapted, for example, on the wagon / container TAL. Those. provide readiness for expanding the functionality of the proposed solution for subsequent interaction, for example, with an autonomous fixing means (latch) in the closed state of the device when an inoperative back loop is formed. Those. it is essentially universal and does not require large changes, and therefore, costs.

Disclosure of invention

This technical result is achieved due to the fact that in 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, made with a sharp point to facilitate its passage through the inlet and outlet openings of the housing and located between they passage channel, with the formation of a loop is fixed in it when closed by a locking mechanism located in the housing, according to the invention, the free end of the rope the tip, which is made in the form of a rod with a head, rigidly attached to the end of the free end of the rope segment, and the diameter of the tip head is made smaller than the diameter of the rope segment, and the sharpening is made over the length of the section equal to at least the diameter of the rope segment.

The invention is characterized in that

- the tip is made in the form of a metal rod with a head and is attached to the end of the free end of the rope segment by welding or glue;

- the tip is made in the form of a plastic rod with a head and is attached to the end of the free end of the rope segment by means of glue;

- the tip head is made semicircular;

- the tip head is made conical;

- the tip is attached to the end of the free end of the segment of the rope with the possibility of its separation with a force not exceeding 1000 N;

- equipped with a latch located in the rigidly closed module cover of the autonomous module, having a shell-case and an autonomous hole for the tip and having the possibility of mounting it on the device, while the latch is made in the form of a fixing washer with internal petals, rigidly fixed together with the module cover in the housing - a shell interacting in a closed state with the tip head, while an autonomous hole is made in the module cover;

- on the case there is a place for applying the necessary sealing information.

The above allows us to conclude that the claimed solution meets the criterion of "novelty"

Below the invention is illustrated by way of example with the accompanying drawings.

The implementation of the invention

Flexible locking and sealing device contains a housing 1 and a piece of rope 2, one end 3 of which is passive, and the second free end 4, made with a pointed 5 (figure 3), obtained by soldering or otherwise to facilitate its passage through the input 6 and the outlet 7 of the housing opening and the passage channel 8 located between them, with the formation of a loop, is fixed in it when closed by the locking mechanism 9 located in the housing. In the above example, the locking mechanism includes a spring-loaded locking element, for example a ball (roller) 9.1, which is partially placed in an inclined hole 9.2, communicating with the passage channel 8.

According to the invention, the free end 4 of the rope segment with a pointed 5 is made on a relatively small length (Fig. 3), equal to at least the diameter of the rope, for example, 5.2 or 4.8 mm (GOST 3067-88) (also the sharpening can be equipped with a cap 5.1), thereby increasing the flexibility of the free end. The sharpening is equipped with a tip 10, which is made in the form of a rod 10.1 with a head 10.2, rigidly attached to the end 11 of the free end of the rope segment, the diameter of the tip head being made smaller than the diameter of the rope segment.

The tip head can be made semicircular (figure 3) or conical (figure 4), or any other shape. The tip 10 can be made in the form of a metal rod with a head and is rigidly attached to the end face 11 of the free end of the rope segment by welding or by means of glue. The tip 10 can also be made in the form of a plastic rod with a head and is rigidly attached to the end face 11 of the free end of the rope segment by means of glue. In this case, you can use conventional adhesives, such as Moment, or Poxipol glue (liquid welding) - an adhesive that has metallic hardness, does not rust and does not change its properties.

Figure 3 and Figure 4 below show examples of attaching the tip by welding or glue: figure 3 - the tip with a round head is attached to the end 11 of the free end of the segment of the rope;

figure 4 - the tip with a conical head is attached to the end of the free end of the segment of the rope through the cap 5.1. It is advisable that the tip was attached to the end 11 of the free end of the rope segment with the possibility of its separation with a force not exceeding 1000 N.

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 6 and then through the passage channel 8. Due to the fact that the sharpening (soldering) at the free end is made on a relatively small length, the free end becomes less rigid and upon contact with the edge of the inlet, it does not slip, but passes inside it without much effort and repeated manipulations and, with further advancement, begins to interact with the spring-loaded locking m-ball element 9.1, squeezes it into an inclined hole 9.2, allowing the passage of a piece of rope 2 through the passage channel 8 and then through the outlet 7. The resulting loop of the rope at the eyes of the locking unit is tightened to form a loop of minimum size. With the cessation of the application of force on the segment of the rope, the ball 9.1, under the action of a closure spring, moves up and reliably fixes it in this position. In this form, the device can be used to seal any cargo - this is a classic option. When you try to force the extraction of the segment of the rope 2 from the housing 1, the ball 9.1 under the action of friction forces begins to increasingly go out of the inclined hole 9.2 into the passage channel 8, preventing the extraction of the segment of the rope 2 from the housing 1, and the greater the amount of extracting force, the greater the degree of jamming (locking) the rope in the body.

Moreover, the proposed tip works like a regular free end of a segment of a rope with a point or equipped with a cap, but the point is made over a relatively short length - this saves expensive material and saves time when processing it, and thereby increases the flexibility of the tip and the ability to carry out it at any additional cost lengths and with any shape of the head (spherical, conical, pointed, sharp, with rounding, etc.) and its diameter. In known solutions, it is practically impossible to obtain this.

In addition, unlike the prototype, the proposed tip can be readily used as an intervention indicator for unauthorized opening of the device by penetrating into its body through the inlet 6 with any tool for subsequent manipulation of the locking mechanism 9.

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 housing is not excluded, and therefore, the contact of the instrument with the locking mechanism is not excluded, followed by pulling the rope in the reverse direction, stealing the contents , and again locking. Moreover, this may be unnoticed before the arrival of the goods.

To exclude the latent criminal impact on the locking mechanism 9 through the outlet 6 of the housing (cover) and serves as a latch 12 (figure 3) as a means of tamper control, which interacts with the tip 10. It should be noted that the location of the latch on the ZPU and its design can be a separate subject of the invention. In confirmation of the foregoing, the latch can be made, for example, in the form of a locking ring mounted in an annular groove of the housing interacting in a closed state with the tip head (not shown in the drawing).

Also, the latch can be made in the form of a plastic latch (not shown in the drawing).

In the example shown (Fig. 3), the latch 12 is located in the rigidly closed module cover 13 of the autonomous module 14, having a shell-case 15 and an autonomous hole 16 for the tip made in the lid 13, the latch being made in the form of a fixing washer with inner lobes 12.1 ( 5 and 6), rigidly fixed together with the cover of the module 13 in the housing-shell 15, interacting in the closed state with the head 10.2 on the tip. Stand-alone module 14 has the ability to mount it on the device by, for example, its hard mount (figure 2).

After the ZPU is closed, the tip 10 of the free end 4 of the segment of the rope 2 is inserted into the hole 16 in the cover 13 and then, overcoming the force of the spring lobes 12.1 of the clamp 12, the conical section of the tip spreads them apart, and when it is further advanced, they fall behind the head 10.2 tip, preventing it from being removed from the housing - shell 15. Checking the reliability of the fixation of the tip is done by manually trying to remove it from the module housing with little effort. It is advisable that the length of the rod be equal to at least the thickness of the lid and the thickness of the latch, which will prevent the penetration of any tool inside the casing for manipulating the petals and then removing the tip from the stand-alone module.

Now, for unauthorized opening of the device, the attacker needs to first release the tip, i.e. remove (pull) it from the latch 12. In this case, two options are possible: either the tip will break, or it will come off the rope in the case when the extraction force exceeds 1000N. These actions will be obvious, i.e. removing the tip without destroying the tip or removing it from the length of the rope becomes obvious - they will not be unnoticed. At the same time, this effect is achieved by supplementing only one detail. A new quality is ensured with almost 100% unification of the device, thereby minimizing the time and cost of preparing the production.

Before authorized opening of the device, which is carried out by biting a piece of rope with a special tool, it is necessary to visually check the tip: its fastening reliability and integrity.

On the device’s body there is a place for applying the necessary sealing information. Technical solutions similar to the proposed one, the set of features of which would coincide with the features of the claimed object, were not found. Therefore, the proposed solution meets the sign of "inventive step".

The disclosed preferred embodiment is provided by way of illustration and not limitation. The present invention allows to save expensive material, time and readiness allows you to expand the functionality of the ZPU.
