Description

FIELD OF THE INVENTION

The invention relates to the field of hardware and can be used for locking and simultaneously sealing cargo containers, refrigerators, vans, warehouses, doors of storage facilities, as well as other objects, providing control and protection against penetration and unauthorized access to goods containing holes in locking and sealing nodes not less than 7 mm.

State of the art

A locking and sealing device (ZPU) is known, in the case of which two parallel channels are made for accommodating the legs of the U-shaped handle after passing it through the locking unit. Each leg is equipped with cutouts, with each of which interacts with a spring locking element. The bottom case is closed by a lid (US Patent No. 3966247).

Also known locking and sealing device described in patent RU No. 2183240, E05B 9/02, which we adopted as a prototype. The device consists of a housing having two blind parallel channels, in which the legs of the U-shaped bow are placed in the locking state, which interact with the spring locking element located in the cradle of the housing. A common disadvantage of the known devices is that the body and the U-shaped handle are two separate elements that require their preliminary fastening, subsequent disconnection and hanging on the locking unit, holding them with both hands. The last drawback creates inconvenience in use, and the first two drawbacks require both time for fastening and separation, and additional material costs. The technical result of the invention is the elimination of these disadvantages.

SUMMARY OF THE INVENTION

The specified technical result is ensured by the fact that a locking and sealing device containing a housing with two parallel blind channels, in which the legs of the U-shaped arch are placed in the locking state, at least one of which is equipped with sockets interacting with a spring locking element located in the lodgement case, according to the invention is equipped with means for pre-fixing the U-shaped bow in the case, while the spring locking element is made in the form of a plate latch having on the front side, a series of locking protrusions made in the form of petals bent in the direction of locking at an angle, interacting when locking with sockets on the leg, made in the form of through holes, and the number of through holes and bent petals interacting with each other is at least two, while the means of preliminary fixation P -shaped arches made in the form similar to the mentioned petals, bent in the direction of locking at an angle of the petal, located on one axis above the other petals, elastically inter acting with the bottom end of the legs.

And also the fact that the legs of the U-shaped handle are equipped with break-in zones for authorized opening.

And also due to the fact that there is a place on the case for applying a control identification marking.

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

The implementation of the invention

The locking and sealing device comprises a housing 1 with two parallel blind channels 2 and 3, in which the legs 4 and 5 of the U-shaped handle 6 are placed in the locking state, at least one of which 5 is equipped with sockets 7 and 8 interacting with the spring locking element 9, placed in the lodgement 10 of the housing 1. According to the invention, the device is provided with means for pre-fixing 11 of the U-shaped handle 6 in the housing 1. At the same time, the spring locking element 9 is made in the form of a plate latch having a number of fixing lugs on the front side The protrusions made in the form, bent in the direction of locking at an angle of the petals 12 and 13, interacting when locking with the sockets 7 and 8 on the leg 5, made in the form of through holes, and the number of interacting through holes and bent petals 12 and 13 is not less two. In this case, the means of preliminary fixation 11 of the U-shaped handle 6 is made in the form of the aforementioned petals 12 and 13, bent in the direction of locking at an angle of the petal 14, located on the same axis above the other petals, elastically interacting with the lower end 15 of the legs 5.

The housing is closed by a cover 16. The legs of the U-shaped bow are equipped with break-off zones 17 for authorized opening.

On the housing there is a place for applying a control identification marking.

The device, as we see, is a single unit (block, module), and not separate independent elements, as is the case in the well-known prototype. The U-shaped handle is installed in the housing in advance and is held in it by the upper petal interacting with the lower end of the handle. This provides ease of locking.

The device is used as follows. Figure 1 shows the device in a state prepared for locking. Since the proposed product is a monoblock design, when locked it can be held with one hand, the free end of the handle 6 (leg 4) is passed through the combined holes of the locking node of the object of protection. Then it is introduced into the channel 2 until it stops. In this case, the nests 7 and 8 (holes) on the leg 5 interact with the petals 12 and 13. The latter elastically bend into the stop element 9, and after stopping the movement of the shackle 6 fall into the nests 7 and 8 on the leg and ensure reliable fixation of the shackle 6 relative to the housing 1 .

Comparison of the claimed technical solution with the prior art known from the scientific, technical and patent documentation as of 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. That is, 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”.

Analysis of the known technical solutions in the art showed that the proposed device does not follow explicitly from the prior art for the specialist, since solutions having features matching the distinguishing features of the invention have not been identified and the influence of the distinctive features on the technical indicated in the application materials has not been confirmed. result, i.e. the claimed solution has features that are not found in the known technical solutions, and their use in the claimed combination of essential features makes it possible to obtain a new technical result, therefore, the proposed technical solution can be obtained only through a creative approach and is not obvious to the average specialist in this field, t. e. has an inventive step compared to the related art.

The claimed technical solution is industrially applicable, since it can be manufactured industrially in transport engineering and used in other areas of the national economy, it is efficient, feasible and reproducible, and the distinguishing features of the device allow to obtain the desired technical result.
