PATENT OF UTILITY MODEL

ELECTROM EC ANICA SÁTELITÁL DISTANCE CONTROLLED LAND LOCK FOR LOAD CONTAINERS

TECHNOLOGICAL AREA

The present invention belongs to the electromechanical area of manufacturing safety devices powered wirelessly to be attached to cargo containers, and refers to a de-developed mechanism to provide security control and traceability of the contained load, through a robust mechanism adaptable to the bars of the gate of a Dry Van container, whose unlocking of the closing system is carried out wirelessly after executing the security protocols that enable the opening of the container based on a data transmission of its state and geographical location in Real-time online software accessed via the Internet from authorized control centers, including from mobile phones, easy installation, autonomy of operation and - which constitutes a guarantee for the security of goods transported in containers.

BACKGROUND TO THE UTILITY MODEL,

The solutions currently existing in the world of locks are electronic seals which are seals or locks whose closing mechanism is combined with conventional seals (desirable, plastic or bottleneck) and are devices that send information about the closing and opening of the lock only through terrestrial communication networks such as GPRS-GSM-2G-3G being exposed not to transmit in areas of non-cellular coverage; they are devices of high vulnerability since their inviolability depends on a conventional seal.

They are electronic seals that combine with conventional seals without satellite communication or remote opening.

The other modality is the electronic seals that fit the bars of the container and adopt a locking mechanism by means of an external key (conventional lock cylinder). These seals, padlocks or electronic seals, despite its system. The closure is not combined with conventional plastic seals or bottlenecks, its LOCAL opening and closing (in situ) depends on an external key which, when turned, releases a series of internal pinions that enable the displacement of the internal axis of the bolt with one of the locking clamps.

The electronic seal of our invention (Tass üock Container) goes beyond the current solutions by having an autonomous locking system that only requires a movement of the user without place to external objects or components, keys or conventional seals and its opening will be It performs via wireless commands from any computer connected to the Internet, control centers even from cell phones. For this purpose, a special metal alloy has been developed that functions as a frequency collector without exposing the metal structure of the device with armored glass and other materials.

The dual communication of the lock (terrestrial satellite) solves problems of a geographical nature in terms of the non-coverage of mobile communication networks, enabling the precinct to incur transoceanic travel without any risk.

Therefore, the proposed device is the most versatile advanced technology in terms of security for freight containers, as a security system that can be managed from a mobile phone of an interested party having its container in international ports with a just click

TECHNICAL DESCRIPTION OF THE COMPOSITION OF THE UTILITY MODEL,

As illustrated: in Fig. 1 and 2, the lock is externally composed of a rectangular prismatic box (1), _^ made of tempered steel metal material, which has a rear wall or cover (2) that was removed at the bottom edge carry an insurance or anti-hook closure (3).

The top cover (4) has an alloy with fine steel and bronze powder in segments, a composition that serves as a radio frequency collector to counteract the effect of Faraday Cage.

The box has a chamfered projection (5) on the face or back cover that allows a gasket that generates pressure on said face and prevents the entry of dust, water and particles from outside that can affect the internal parts of the lock.

On one of the side walls of the box there is a perforation that allows the installation and support of a bushing body (6) as a projection in 1/3 of its length by one of its ends.

At one end of the box (1) and on the side opposite the bushing (6) there is a handle (16) of ergonomic design (figures 1 and 2), made of steel and used to manually transport the box (1) of the lock, and to install or remove the lock in and from the bars B that serve as a seal on the door of a container. Likewise and opposite each other at each end of the box are two clamps (17) and (17 ^' ) that act as anchoring elements of the lock box on the bars of the container

It should be mentioned that the clamp (17) is fixed to the body of the box (1) while the clamp (17 ^' ) is attached to the sliding shaft (15).

The bushing (6) according to figure 3 is a hollow cylindrical body with a notch or cut (7) which, as will be seen below, allows to accommodate a ratchet mechanism. The bushing (6) is crossed in its extension by a pin (8) and a pin (9).

The pin (8) holds and allows the oscillatory movement of the ratchet (11) (figure 4) and there is also a hole inside the bushing that houses a spring (10) that drives the ratchet.

The pin (9) exerts a lock on a complementary round shaft on the bushing (6) to limit its horizontal displacement as will be seen below.

The ratchet (11) of figure 4 is a piece whose design incorporates an elongated end (12) that fits in the cut or notch (?) Of the bushing, a hole (13) in its gravitational center to hold it to the bushing and give it a oscillation between 5 ^or 10 ° and a housing (15) for the aforementioned spring that repels it from the bushing. On the back of the ratchet there is a toothed area (14) with an inclination of teeth of 40 ° towards the arm (11) of the ratchet.

Inside the bushing (6) and according to figure 6, a round shaft (15) in steel is housed to move it into the bushing and which extends at its end with a handle (18) designed to print the displacement force of said shaft ( 15) inside and outside the bushing (6).

This shaft (15) has a graphed segment (19) that acts as a blocking zone in its movement against the toothed area (14) of the ratchet and also has a circular groove (19 ') that allows to accommodate a packing ring or ring, which waterproofs and gives tightness due to the moving nature of the shaft towards the inside and outside of the box (1).

This shaft (15) also carries a recess (20) to accommodate a pin that crosses the bushing (6) and serves to limit the travel of said shaft. A pair of neodymium magnets that act as sensor elements of the shaft portion (15) are housed on said axis. These neodymium iron boron magnets coated with chromed nickel on the shaft (15) in the extrusion of said piece are designed to exert a magnetic field at the first plate breaker (figure 7) at the bottom of the box (1) and to inform by way of a sensor on the horizontal position of the shaft (15) towards the communication module of the lock in the sense that the gate in the module is open or closed.

Returning to the clamp (17 ') at one end of the box (1) and attached to the shaft (15) according to Figure 2, said piece carries on its rounded spine a grab knob (21) that allows manually adjusting and the pressure against the B bars of the container and prevent its operational vibration.

On the underside of the case (1) there is a rubber support (22) in the form of a cone whose purpose is to limit the position of the lock when it is not in operation, interacting with an accelerator device Three-axis digital meter inside the box, and that connects to the communications module of the lock to send information about e! Lock positioning either at rest or in operation.

Figure 6 shows the inside of the box (1) in its mechanical components comprising an actuator * electro-mechanical (23) microcontrolled with metal pinion and nylon, with an axis that moves a lever (24) cam type on the elongated end ( 12) of the ratchet mechanism which prints an operating torque that ranges between 980 kPa and 1,274 KPa and ^; a 60 ° turn at an action speed between 0.17 and 0.2Q ⁱ seconds.

Inside the box (1) and on the inside of the back cover (2) there is a magnet (25) (figure 2 dashed line) in boron iron neodymium, chromed nickel coated and specially designed to exert a field magnetic to a second reed switch (figure 7) in it electronic communications module and whose function is to inform about the state of the open or closed gate to the communications module.
