The present invention relates to the field of security of multimodal transport containers (such as those transported by rail, trailers, airplanes and ships) and more specifically refers to a closing device that prevents the doors of a container from being opened without the corresponding key, since said device encapsulates the bar lock. Background

There are patent documents CN200994934Y; CN201033686Y; CN201224587Y; CN201224588Y; US5284036A; US5791702A, US5931033A; US6092404A; US7234755B1; US7278284B1; US7278663B2; US7441425B2 and US2009179437A1 are the closest patent documents; however, none of these documents describe a device like the one described in this document. The devices of the state of the art concentrate their efforts in preventing the opening of the doors by protecting the opening of the handle either in the handle itself or in the bar or from its placement inside the container, the present invention concentrates on protecting the zone of the closing locks located at each upper and lower end of each of the closing bars of the container doors. Definition of the problem

Around the world, transport theft rates have skyrocketed; in particular to trains and in general to transport, which circulate on the rail networks with various forms and types of vehicles specialized in transport of goods, products, substances and materials, as well as to the trailers that circulate on the roads and cities where Organized crime operates.

The multimodal transportation containers used to store and move various types of goods inside are vandalized along the seaports where they are unloaded from ships and placed on railway platforms and trailers to their destination. final and the goods stored inside these containers are stolen.

The aforementioned results in millions of businessmen and merchants, insurers and the railway and transport companies themselves.

Solution to the problem

To solve the aforementioned problem, the present invention provides a device that prevents the unintentional opening of container doors.

Brief Description of the Invention

The present invention provides a safety device that prevents the doors of a container from being opened without authorization, even if the container's own closing bars are broken or cut since the device encapsulates the bars' locks and its design is such that it locks the doors.

The safety device of the preferred embodiment of the invention comprises alloy or non-alloy steel plates, placed one above the other, triangular side walls in order to reduce risks of cutting with disc and Leverage with bar and additional reinforcement elements to the structure of both bodies. The above elements are adjusted or coupled so that they cannot be separated by prying between the constituent elements of the device.

From an exterior view it is obvious that the device consists of several pieces; However, it is not obvious how to open the device for someone unfamiliar with it only which results in greater security for charging.

The device generally comprises two metallic or non-metallic bodies, although metallic ones, detachably connected by means of a screw enclosed by a sealing cap, are attached to the device by means of a commercial opening and closing lock by means of a high security key (tetrallave) or equivalent.

Detailed description of the invention

The device is placed on the securing bars of the containers (see figure 2), encapsulating them and preventing them from being manipulated. In the state of the art, the safety closing options are focused on securing the operating handle of the closing bars, the present invention is focused on ensuring the safety of the bars of the container doors. These locks prevent the opening of the doors when the bars have been turned for this purpose.

The proposal of the present invention is manufactured with steel plates with or without heat treatment that give it mechanical strength and safety, reducing the risk of suffering some vandalism to the containers where it is placed.

As can be seen in figure 1, the safety device (1) consists of the following main parts: a. Left body (100).

b. Right body (200).

C. Hermeticity cover (T).

d. Fixing screw (A).

and. Security lock (C).

In general, the device works as follows:

The left body (100) is placed partially covering the lock (2) of the container doors, Immediately the right body (200) is placed, for this, each of both bodies has a crescent that serves to form a semicircle and act as nails to hold the insurance (2) thus allowing to continue with the assembly of the device (1). Once both parts are in the assembled position, the Alien head screw (A) or some other type suitable for work is introduced, screwed into the threaded die (107) attached to the plate (106) and subsequently open the lock (C) (if it is closed) to be able to insert the sealing cover (T) and thus protect the door lock against any unwanted opening, even if the door lock is opened. It is important to note that the outer face of the sealing cap is flush with the corresponding edge of the right body, so it is not possible to insert an object to pry and try to open it.

The left body (100) comprises a left side triangle (101), a left upper triangle (102), both attached to a rear cover (103) which in its upper part comprises a semicircle (104A) that will serve to house the bar ( 3) of the container.

Inside the rear cover (103) a cover (105) is placed (see figures 4A and 4B) to which the perpendicular plate (106) that supports the threaded die (107) that will receive the Alien screw (A) is fixed. In order to give it greater stiffness to the back cover (103) elements (108) which are rectangular elements and plates are placed as shown in Figures 4A and 4B. The plates of these elements (108) are also used to enclose the lock (2) of the container doors. In addition to these reinforcements (108), similar reinforcements (108A) are also placed in the right body (200).

Between the threaded die (107) and the inner surface of the cover (103) is a space (109) (see figures 4A and 4B) into which the plate (110) will be inserted, which protects the screw (A) hindering access to it and preventing it from being cut or damaged in any way.

In order to further protect the screw (A) the plates (111A-111C) are attached to the cover (103) (preferably by welding). The plate (111A) has suitable internal dimensions to match the bent C-shaped plate (201) of the right body (200). The intermediate plate (111B) has adequate internal dimensions and configuration to be placed on the plate (111A) while the external plate (111C) has adequate dimensions to be placed on the plate (111B), where the latter plate (111C) can be of a hardness greater than the plates (111A) and (111B), the union between them will be by means suitable welding such as electric arc welding, TIG, etc.

The right body (200) comprises a C-bent plate (203) to which the plate (110) is attached in its inner part, this plate (110) comprises two longitudinal flanges to increase the area of the plate (110) to the inside of the C-plate (203). At the top of the C-plate (203) a hole (204) is practiced so that the padlock rod (C) passes through it when it is opened.

Opposite to this hole (204) another hole (205) of sufficient dimensions is made for the introduction of the key that opens the lock (C), therefore, this hole is aligned with the lock so that, in operation, the hole (204) with the padlock stem (C) and the key entry of the padlock with the hole (205).

To give greater rigidity to the construction (see figure 10), and therefore greater security, the padlock rests on the plate (206), which, in turn, joins the plate (207), which in turn forms the internal limiting wall of the right body (200). This limiting wall or plate (207) has a hole (208) (see figure 9) sized so that the body of the Alien screw (A) passes through it, but not its head. The screw will be screwed onto the square threaded die (107) located on the left body, which, When the plate (207) is integral with the right body and the square threaded die (107) with the left body, the screw will join, by threading, both bodies (100 and 200). As can be seen in the figures, the larger surfaces of the plates described are parallel with the larger surfaces of the padlock.

While the screw is inserted into the square threaded die by screwing, the plate (110) integral with the right body is inserted into the space (109) (see figure 4B) located between the square threaded die (107) and the inner side of the cover (103). Obviously, the screw must be of adequate mechanical strength and length for this purpose.

Mounted on the top of the plate (203), a cover (209) is located to increase the rigidity of the right body (200), protect the padlock rod and manipulate the same rod to close the padlock. This same cover (209) has a small hole (210) which will serve to hold one end of a cable (211) and the same cable at the opposite end to the sealing cover through a protrusion with hole (212 ), to provide that the lid can be separated without being an independent part of the right body.

Under the sealing cover and in order to prevent access to the same cover and that the device in In general, it is subject to separation by means of a lever, that is, to prevent an object from being inserted to separate it when it is in the working position, the triangle (213) is placed, whose non-inclined part rests on the container frame.

As can be seen in Figure 3, the sealing cap is composed of 3 elements,. an external plate (Ti), an internal plate (T2), of smaller dimensions, and a suitable body (T3) so that the padlock rod passes through it.

To complement the operation of the cover (T), the upper right side plate (214) and the lower right side plate (215) are placed. Between these two plates there is a gap sized so that the internal plate (T2) and the body (T3) are inserted into it.

The body (T3) has a hole sized and positioned so that the padlock rod passes through it. When passing through the hole of the body (T3), the rod secures in a position, that it cannot move in any direction, to the sealing plate, whereby the screw (A) is not accessed.

The lower right plate is welded to the plate (203) and the triangle (213), note that the plates (214 and 215) are not flush with the edge of the plate (203), but a little towards the inside, this displacement is equivalent to the thickness of the plate (Ti), so that when the sealing cover (T) is introduced, its outer surface is flush with the edge of the plate (203).

The invention has been described so that a person with average knowledge in the field can reproduce it; however, there are variants that should be considered during its implementation. These variants can be for example the construction of some of its components not as plates but as molten products and can be joined by means other than welding, without such changes being outside the scope of the invention described and for which its limited protection is requested for the scope of the following claims.
