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) equipped with a tamper-evident control device. At the same time, the latter can be made in the form of a tip of the free end of a rope segment fixed in a self-contained hole in the housing of the ZPU with the formation of an inoperative back loop in the closed state of the device.

State of the art

A flexible locking and sealing device is known that has a means of fixing in a standalone hole in the housing of the ZPU the tip of the free end of the rope segment with the formation of an inoperative back loop in the closed state of the device, described in patent RU No. 103558 (E05B 39/03). It is made in the form of a petal washer mounted in the side of the housing in a two-stage hole and interacting with the surface of the annular groove made on the tip after it is pushed through the hole when an inoperative back loop is formed.

Closest to the proposed one is a ZPU with means for fixing the tip of the free end of the rope segment with the formation of an inoperative back loop in the closed state of the device described in patent RU No. 2396405 (E05B 39/02), which also uses a tip mounted on the free end of the rope segment and on which a neck is made, interacting when pushing the tip in the closed state of the device with a spring clip mounted inside the bottom cover. As a prototype, invention No. 2396405 was selected for the reason that it was modernized while simplifying the design of the cover and other parts of the device.

The disadvantages of the analogue include the need to manufacture a new metal-intensive casing to accommodate the flap washer in its lateral part, and the disadvantages of the prototype are the presence of a metal-consuming, voluminous (thick) and difficult to handle cover, which led to a subsequent change in the design of the device, including the need performing an additional hole in the side face of the body, combining it with an autonomous side hole in the lid, which is not technologically advanced.

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

Disclosure of invention

The specified technical result is achieved by the fact that in a flexible locking and sealing device with means for fixing the tip of the free end of the rope segment in the closed state of the device, comprising a body closed by upper and lower covers, and a rope segment, one end of which is passive, and the second free end, equipped with a tip with a neck, is passed through the inlet and outlet openings of the housing and the passage channel located between them with the formation of a loop and is fixed in it when closed by means of a fur the locking bottom located in the housing, comprising at least one locking element spring-loaded with a closure spring, the lower end of the closure spring being mounted in the spring stabilizer, and the tip fixing means in the closed state of the device is made in the form of a spring retainer mounted in a side independent hole in the lower a cover made at an angle to the outlet, interacting with the neck of the tip after pushing it through an autonomous hole for the tip to the bottom to the lid during the formation of a non-working back loop, according to the invention, the spring clip is made in the form of a curly thin metal plate having a spring holder interconnected by a narrow section at one end with rectangular symmetrically located cutouts relative to its longitudinal axis, which coincides during installation with the axis of the closure spring made on its lateral sides to ensure that it is mounted in the lower part of the closure spring in its inter-turn space, serving simultaneously as a stabilizer rupture of the closure, and on the other end bent with a radial rounding at an angle, the engagement of the neck of the tip, partially overlapping the autonomous hole and placed in the slot for the hook, in a cross section preferably rectangular in shape, made in the bottom cover crossing the autonomous hole, with the plate in the lower part equipped with a technological hole through which it is mounted inside the housing at the passive end of the rope segment, and a parallel section bent under a small radius, on which the specified hook of a neck of a tip is put.

And also by the fact that the hook of the tip neck bent with a radial rounding at an angle rests on the lower face in the hook slot, and the angle at which the hook is bent up is made in the range from 30 to 60 degrees.

And also the fact that the radius cutout of the engagement of the neck of the tip is made equal to at least half the diameter of the neck of the tip.

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

The implementation of the invention

The proposed flexible locking and sealing device with means for fixing the tip of the free end of the rope segment in the closed state of the device with the formation of an inoperative back loop contains a housing 1 closed by upper 2 and lower covers 3, and a rope segment 4, one end of which is passive 4.1, and the second is free the end 4.2, equipped with a tip 5 with a neck 5.1, is passed through the inlet 6 and outlet 7 of the opening of the housing 1 and the passage channel 8 located between them with the formation of a loop and fixed in it when the circuit closes COROLLARY locking mechanism 9 disposed in the housing, comprising a spring spring-loaded closure 9.1 at least one locking element 9.2 (roller or ball), the lower end of the spring is mounted in a 9.1-circuit regulator circuit 10 of the spring. In this case, the tool for fixing the tip in the closed state of the device is made in the form of a spring clip 11 mounted in a side independent hole 12 in the bottom cover 3, made at an angle to the outlet 7, interacting with the neck 5.1 of the tip 5 after it is pushed through the independent hole 12 for the tip in the bottom cover 3 with the formation of a non-working back loop.

According to the invention, the spring clip 11 is made in the form of a curly thin metal plate having interconnected by a narrow section 11.1 at one end of the spring holder 11.2 with rectangular symmetrically located cutouts 11.3 relative to its longitudinal axis, which coincides during installation with the axis of the closure spring 9.1, made on its sides to ensure that it is mounted in the lower part of the closure spring 9.1 in its inter-turn space, serving simultaneously as a stabilizer 10 of the closure spring 9.1, and at the other end the hook 11.4 of the tip 5.1, bent with a radial rounding at an angle, partially overlapping the autonomous hole 12 and placed in the nest 3.1 for the hook, preferably in the cross section of a rectangular shape made in the lower cover 3 intersecting the autonomous hole 12, while the spring clip 11 in the lower part is equipped with a technological hole 13, through which it is mounted inside the housing at the passive end 4.1 of the rope segment, and parallel section 14 bent under a small radius, on which n said hitch neck 5.1 11.4 tip 5.

It is provided that the hook 11.4 of the tip 5.1 of the tip 5, bent with a radial rounding at an angle, rests on the passive end 4.1 of the rope segment, and the angle at which the hook 11.4 is bent up is made in the range from 30 to 60 degrees. This ensures the rigidity of the spring clip design, as he has a footing.

It is also provided that the radius cutout of the hook 11.4 of the neck 5.1 of the tip is made equal to at least half the diameter of the neck of the tip. This ensures the reliability of the engagement of the neck.

On the body there is a place for applying the necessary sealing information.

The device is used as follows.

When locking, the free end 4.2 of the rope segment 4 is sequentially passed through the holes of the eyes of the locking object, the inlet 6 and then through the passage channel 8. The free end 4.2 begins to interact with the spring-loaded locking mechanism 9, depresses the locking elements 9.2 along the longitudinal axis of the housing, and allow passage of the rope segment 4 through the passage channel 8 and then through and the outlet 7. Then the rope segment is manually tightened until a minimum loop is formed. With the cessation of the application of force on the segment of the rope, the locking element 9.2 under the action of the closure spring 9.1 moves towards the closure and reliably fixes it in this position.

But since there are technological gaps between the segment of the rope 4 and the inlet 6, from the inlet side the introduction of any tool into the body is not excluded, and therefore, the contact of the instrument with the locking mechanism and the subsequent pulling of the rope in the opposite direction, theft contents and re-locking. Moreover, this may be unnoticed before the arrival of the goods.

To eliminate the secretive criminal effect on the locking mechanism through the inlet 7 of the housing (cover), there is an unauthorized opening control device mounted on the side of the housing in the lower cover 3, which serves as a means for fixing the tip 11 in the closed state of the device, made in the form of a spring clip 11 with a hook 11.4, interacting with the neck 5.1 of the tip 5 after pushing it through an autonomous hole 12 under the tip in the lower cover 3 when an inoperative war loop.

It works as follows.

The tip 5 of the free end 4.2 of the segment of the rope after the ZPU is brought into a closed state with the segment of the rope tightened until a minimum loop is formed, is introduced into the autonomous hole 12 in the lower cover 3 and then pushing it further, overcoming the force of the spring-loaded portion 11.4 of the retainer 11, the conical section tip 5 takes it to the side, and with further advancement, the hook 11.4 falls over the neck 5.1 of the tip. The reliability of the fixation of the tip is checked by trying to manually remove it from the housing (cover 3) with little effort.

Now, for an unauthorized opening of the device, the attacker must first release the tip 5, i.e. remove (pull out) it from the latch 11. In this case, two options are possible: either the tip will collapse, or it will be removed from the segment of the rope.

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.

This achieves this effect in comparison with the prototype, including without making an additional hole in the side face of the body, combining it with an autonomous side hole in the lid, which is not technologically advanced. Almost 100% unification of the case, springs and other parts of the basic device is ensured, thereby the time and cost of preparing the 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 “inventive step”.

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.

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

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 reliability of fastening in the lid and integrity.

Thus, the present invention allows to provide both control of an unauthorized opening, and in general to increase the degree of protection of the ZPU from its unauthorized opening.
