DETAILED DESCRIPTION OF THE INVENTION

[0086] The safety lock with double closure, object of this Invention patent application, has several characteristics that distinguish it from other locks/door locks from the state of the art.

[0087] As an outstanding feature, the increase in security levels provided by the safety lock with double closure that is object of this patent provides is highlighted, considering that its locking method consists in two linear locking axles, opposite to each other so that, when installed on a door either for access control or on a vehicle cargo compartment, the door is locked in two opposite points, increasing the difficulty of breaching and subsequently the degree of security when compared to other locks in the market.

[0088] Another outstanding feature is related to the possibility for portability, considering that the lock that is object of this Invention patent has easy installation and removal as its technical differential, provided the special tool 3.2.1 is used, equipped with a coupling mouthpiece 3.2.1.1 with an internal protrusion 3.2.1.2 compatible with the cavity 3.3 provided on the head 3.4 of the screw 3.2 to release the front safety screws 3.2 with customized heads 3.4.

[0089] This feature is widely used in cargo box, vans and container doors, considering that in such cases, this portability is required and the use of a lock only for cases in which the vehicle/container holds cargo that the client and “lock/door lock owner” needs a more effective control and increased protection of the cargo. For this purpose, the installation of the full lock kit is required (this kit is manufactured for each application type, comprising the lock, the yoke nut and the customized safety screws, components included in all kits equally) which will be permanently attached to the door. This kit has low cost and, when installed, shall enable the portability of the lock, requiring only the connection of the nuts present at the end of each lock axis, the bars already included and attached to the door, in addition to the fastening of the lock using the special headed screws and automotive-type power feed connection plug already installed and positioned beside the lock fastening location, in other words, if the lock installation kit is already being used on the vehicle door, the only thing needed for installing and detaching the safety lock with double closure that is object of this Invention patent is connecting and disconnecting the front screws, the interconnection nuts of the lock axis to the locking and feeding axles, which are all included and installed on the door. This leads to logistic and financial gains, considering the locks will be used in vehicles/doors needed according to the cargo transported and do not require any specialized professional for replacement and installation, with no scheduled dates or vehicle displacement, and may be carried out by the client's staff itself (“lock owner”).

[0090] Another major highlight is in the operational aspect, considering that this safety lock with double closure, object of this Invention patent application, does not exclusively require trackers for operation, as with the other locks already known and belonging to the state of the art. This model includes an internal module for Bluetooth/Wi-Fi communication as its distinguishing feature, enabling lock activation through a smartphone application developed by the Applicant which, in combination with the aforementioned Bluetooth/Wi-Fi module, controls all actions of the lock and other sensors, mainly lock opening and closing through the smartphone with encrypted commands, open and closed door status, locked and unlocked pin status, door violation status, pin not reached end of course status, monitoring of engine running current for detection of possible wear and allocation for preventive maintenance, internal box temperature status through the OneWire network, accelerometer for identification of installation position and possible breach, guaranteed opening only in valid pre-recorded points, predefined door opening time control as safety rule with alarm generation when breached, showing as a warning: “Door opening time exceeded”, “Encrypted” door opening and closing sensor with factory configuration and registration, preventing breaches using magnets and other materials as occurs in models widely used in the market (reed switch type magnetic sensor), therefore a “lock closure failure” is able to set off an alarm if it fails to reach the end of its locking course, control of door opening and vehicles per pre-recorded user on the cloud-based webservice, in other words, a series of validations and safety information required that are not included in the locks/door locks already known in the state of the art.

[0091] In reference to figures previously listed, the lock that is object if this Invention patent application, it is observed that in FIG. 7 the detail of the gear 1.4.4 of engine 1.4 which engages the rack 1.2.4 of the front axis 1.2, which follows patent MU 8601581-8, also fits the rack 1.3.4 to the rear part 1.3, different than the previous patent for being single axis, to perform the locking and unlocking movement of the front 1.2 and rear axles 1.3.

[0092] It is observed that both the front axis 1.2 and the rear axis 1.3 slide inside a bearing 1.1.1 and are supported on base recesses 1.1 and run through respective pins 1.1.3 which are lodged in respective oblong openings 1.2.5 and 1.3.5 which serve both as guides for alignment and for preventing extra movement from said axles in relation to the engine course 1.4.

[0093] The racks 1.2.4 of the front axis 1.2 and 1.3.4 of the rear axis 1.3 with pitch and module established as per the gear 1.4.4 of engine 1.4, in other words, according to the variation of the engine model 1.4, at some point the axis racks may undergo changes in format, number of teeth, module, etc.

[0094] The rear axis 1.3 comprises two ends, one of the ends already welded to the rack 1.3.4 and another loose threaded end 1.3.3, to allow for assembly of the cover 1.10, which may be seen in FIG. 4 with the entire base assembly and after this end 1.3.3 is threaded with chemical fastener, and leaving the entire set of lock 1 assembled and ready for installation.

[0095] The dimensions of base 1.1 and axles, both from the lock and its extenders, and may also undergo changes as needed for each project. The projects are comprised as follows: first the location of the lock installation shall be defined in order to acquire the measures of the extender axles according to the total locking course defined by the application; and afterwards, the engine 1.4 and other components (electronic and/or mechanic), which may be placed inside the base 1.1 in order to address all needs established from the start.

[0096] This definition is extremely important so that all components are allocated inside the lock 1 to prevent any violation to any internal components and the efficiency of lock 1 is affected.

[0097] FIG. 1 shows all main components for the basic operation of the lock that is object of this patent application, which are attached to the base 1.1, comprising a bearing 1.1.1 welded to the base 1.1 for the front axis 1.2, the same bearing 1.1.1 welded to the base 1.1 for the rear axis 1.3, and all proper reinforcements 1.1.2 welded around the bearing 1.1.1, two pins 1.1.3 welded to the base 1.1 to prevent the axles from exceeding the course of the engine 1.4 and also to maintain proper guidance for the entire movement. This top 1.1.3 eliminates the need for the use of a rear bearing. Inside the casing of the bearing 1.1.1 where each axis runs through the course limited by the engine 1.4 which, in turn, is fixed to the base 1.1 by three M6 pan head Allen screws 1.4.2 supported by a sleeve 1.4.1 which has the height needed to apply pressure of the engine housing 1.4 in relation to the axles. The M6 pressure washer 1.4.3 with the use of chemical fastener, ensures engine stability and fastening, to prevent vibrations caused by the use of the lock from loosening the attachment and release the motor for its position. The axles are supported on recesses on the base 1.1, thus in conjunction with the engine pressure and alignment of the bearing 1.1.1, maintaining alignment to the holes on the cover 1.10, which may be observed in FIG. 8, leaving the movement stable throughout its linearity. The Bluetooth/Wi-Fi module 1.5 by two M4 Phillips screws 1.5.1 with pressure washer and chemical fastener.

[0098] The engine 1.4 performs the locking and unlocking movement, when turning to the clockwise and counterclockwise directions, the motor engagement with the rack of the front 1.2 and rear axles 1.3 transfers the radial engine movement in a linear movement of the axles, performing the locking and unlocking functions.

[0099] FIG. 5 or 6 show that the feeding of the engine 1.4 is carried out by the Bluetooth/Wi-Fi electronic module 1.5, which is inside a plastic box 1.5.9 (visible in FIG. 20) including a hall sensor 1.5.7 activated by a magnet 1.2.3 fixed to the front axis 1.2, thus the sensor indicates the position of the axles to the Bluetooth/Wi-Fi module 1.5 and drives the engine in the correct movement direction.

[0100] FIG. 2 shows two limit stop switches, one at the front 1.8 and one at the rear 1.9 that are attached to a steel plate 1.8.1 by two M3 flat head Allen screws 1.8.4 and by pressure washer and nut M3. In turn, the plate is fixed to the base 1.1 by a set of M6 Allen screws 1.8.7, M6 pressure washer, the limit stop switches are mounted to the base 1.1 indicating the position of axles for the activation peripherals, when an internal tracker 1.7 is used in addition to the Bluetooth/Wi-Fi module 1.5, with the front 1.8 when driven indicates the “closed” state, in other words, locking state, and the rear limit stop switch 1.9, when activated, indicates the “open” state, in other words, unlocking state. The limit stop switches in their activation points have a pulley format, providing reliability to the actuation of the limit stop switch.

[0101] The functioning of these switches may be compared to the use of a button which, when activated, connects two contacts and sends a positive signal to the peripheral.

[0102] The Bluetooth/Wi-Fi module 1.5 has the objective of coordinating inlets and outlets of the entire lock, with the activation signals as the inlet, either through an internal tracker 1.7, according to patent MU 8601581-8, as may be observed by FIG. 5 or 6, or even activation by an RE external tracker, or activation via the Bluetooth/Wi-Fi module 1.5 itself which requires a counter-password authorization generated by a restricted access center (10.2) developed by the Applicant, seen in FIG. 13.

[0103] The signals of hall sensor 1.5.7 indicate the direct position of the axis to the Bluetooth/Wi-Fi module 1.5 and the signal sent via sensor installed to the set of doors, either magnetic 6 (most known and used) or an encrypted sensor 7 which works in pair 7.1 with a tag that only corresponds to it. The sensor signal when received by the Bluetooth/Wi-Fi module 1.5, understands that lock 1 must be closed, so when closing the set of doors to which it is connected, lock 1 closes automatically with the set of doors. The outlet of the Bluetooth/Wi-Fi module 1.5 is the feed of the engine 1.4 when, for each state received inside the Bluetooth/Wi-Fi module 1.5, the outlet polarity is inverted in order to invert the engine movement in both directions.

[0104] The model of the Bluetooth/Wi-Fi module 1.5 has a OneWire communication network 1.5.2, in order to address temperature measurement needs in a cold chamber, for example. These temperature sensors 1.5.2 are connected to the Bluetooth/Wi-Fi module 1.5 through three cables. The first positive feed cable for the sensors, the second cable for communication (information sending and receiving), this connection type is known as OneWire, and the third cable for negative feed. This extra communication capacity through the OneWire enables adding up to eight temperature sensors (waterproof) for monitoring the cargo compartment and activating a function inside the Bluetooth/Wi-Fi module 1.5 called “Quebra-Gelo [Icebreaker]”.

[0105] This “Quebra-Gelo” function aims at analyzing if a specific routine must be performed, through measurement of the container temperature, since after a certain period, open or closed, lock 1 can become frozen. Such cases occur in cold chamber compartments, where the temperature may reach −40° C. Therefore, the activation of lock 1, either for opening or closure, cannot take place in a single command, then the Bluetooth/Wi-Fi module 1.5 performs a routine, sending various shorter commands, until the status is modified (the lock reaches the course end on the hall sensor 1.5, or limit stop switch when used in extra inlets).

[0106] Another one of the functionalities of the Bluetooth/Wi-Fi module 1.5 that may be seen in FIG. 19 is the capacity for connections to other peripherals, through use of wi-fi technology and discarding the use of any wires for integration and control of other peripherals that bare installed and made use of the same module, for example, in truck applications, fifth wheel lock 11, another lock 1 installed to the side door of the cargo compartment, a wireless blocker 12, a wi-fi video camera 13 to record the opening and closing moment, such as in various other peripherals that may be integrated, as per operation planning and client needs.

[0107] Another important sensor included in this Bluetooth/Wi-Fi module 1.5 is the three-axis accelerometer 1.5.8 which allows identification of the position of lock 1 at the time of installation, therefore, if it undergoes any movement on the axles outside a pre-established tolerance, such as releasing the lock from the original position to prevent it from performing the locking correctly, this will be identified in this module and an alarm signal will be sent to the tracker (internal or external) or application for use 10 and the responsible personnel will be noticed in order to reposition lock 1 at the original location, thus avoiding frauds and undue incidents. These needs shall depend on each specific client project. In conjunction with the accelerometer 1.5.8, another sensor is already assembled to the Bluetooth/Wi-Fi module 1.5, in which a luminosity sensor 1.5.10, more commonly known as LDR, is able to identify through the light. This LDR sensor 1.5.10 corresponds with a hole 1.1.4 at the base 1.1 for light passage. Base 1.1 receives a resin layer, or any other kind of polymer, transparent to maintain sealing as a hole and also allow for light collection at the sensor point, to identify if lock 1 was removed from its position or not.

[0108] In order to prevent any violation of this sensor LDR 1.5.10, the set of the accelerometer 1.5.8 sensor and the LDR sensor 1.5.10 prevents non-authorized people from moving lock 1 from its position such as originally installed. Then an alarm is sent to the tracker (internal or external) and the Webservice center 10.2.

[0109] The Bluetooth/Wi-Fi module 1.5 also includes extra inputs and outputs to address more applications. An external physical keypad 1.5.3 may be added for combined activation with the other possible methods. Another possible addition are said limit stop switches for, in conjunction with the hall sensor 1.5.7, opening and closing the lock 1. An alarm siren 1.5.6 may also be added to the Bluetooth/Wi-Fi module 1.5 outputs to signal the user/driver, through sound alarms, safety warnings pre-set on the webservice 10.2.

[0110] Another optional feature for the lock 1 is a backup battery 1.5.4, as seen in drawings 5 or 6, for opening in case of power outage, for facilities where the lock 1 is fed through a conventional power network (127/220 Vca), or in case of battery depletion of the installed vehicle. This backup battery 1.5.4 may also be equipped with a solar charger 1.5.11 for better energy use and a lower consumption in the main power source.

[0111] FIG. 5 shows that two sets of electric cables come out of lock 1, and if used with additional sensors and/or actuators 1.5.1 another set of cables is added. A set of four cables for a safety opening switch 1.6.1 and another with four cables (five in case of emergency button usage) for the use of a magnetic sensor 6, or in FIG. 6 where it is possible to see two cable sets, and if used with more sensors and/or actuators 1.5.1 another cable set is added. A set of four cables for the emergency opening switch 1.6.1 and another set of seven cables (eight when the emergency button is used) with the use of the encrypted sensor 7. Said cables are assembled near an automotive-type connector that ensures the connection remains up at all times, unless disconnection is forced.

[0112] From the four cables of the first set seen when the magnetic sensor 6 is used, the first cable is a positive connection of lock 1, where it should be plugged to a 12/24 Vcc power source (bi-volt), the second cable is the negative connection of lock 1 and must be grounded, or connected to the negative side of the power source, the third cable is the pulse of the sensor 6, which indicates if the set of doors where it is installed is open or closed, and the fourth cable is the inlet of an external tracker RE, or internal that is placed inside the lock assembly, as per MU 8601581-8. The second set of cables is from an emergency connection of a second electronic module 1.6 (which is also placed inside a plastic box 1.6.4) which is actuated when in contact with a special safety switch 1.6.1, to be used only in case any other actuation method does not work. Its operation is through RS485 technology, totally disconnected from the previous circuit and no active feeding by the same network of the Bluetooth/Wi-Fi module 1.5. This module RS485 is off all the time and is only activated (external feeding) when the external safety switch 1.6.1 is connected to a plug available in the connections input of lock 1. With this safety switch, the lock may be opened independently of the tracker (internal or external), or the Bluetooth/Wi-Fi module 1.5 This safety switch 1.6.1 cannot be in possession of the operator/driver/user. It must be kept by the clients' security department, because its use is restricted and must only be used in contingency, in other words, only when opening methods using trackers (internal or external) and opening through the Bluetooth/Wi-Fi module 1.5 are not possible (in case of failure). This special safety switch 1.6.1, before use, must first be recorded through a recording module 1.6.2 receiving information regarding user, place of use, date and time as a use interval, from the webservice platform of the Applicant 10.2. This information received from the recording module are saved in the safety switch through a cable, and afterwards the switch is ready for opening.

[0113] It should be noted that the Bluetooth/Wi-Fi module 1.5 works in combination with the application for use 10 when deployed in projects where the lock is used by mobile users or by an interconnected Wi-Fi network for opening by a remote team.

[0114] The set of seven cables derived from the lock if an encrypted sensor 7 is used, two connectors are considered, one being a three-way connector for feeding the lock, and an external RE tracker input. And the other exclusive sensor connector, with the first cable for positive feed of the sensor, the second cable for negative feed, the third being a communication sending wire and the fourth cable being a communication receiving wire. In addition, it has the same set of cables previously presented for opening in case there is no activation.

[0115] Optionally, a button for emergency opening 9 may be installed, along with the entire set of the lock 1, so in potentially deadly incidents, in other words, the user/driver being trapped inside the cargo box, a container or a vault room, it is still possible to open from the inside.

[0116] After all components are assembled on the base 1.1, the connection cables of the lock 1 are passed through the hole on the cover 1.10, where a PG-11 standard cable gland 1.10.2 helps in sealing the lock, on the cover 1.10 there are five bushings 1.10.1 for better guidance of the screw when using the fastening of the lock 1 onto installation surfaces. The cover 1.10 is attached to the base 1.1 by eight self-tapping 3.5 Phillips screws 1.10.6, said components may be seen in FIG. 4.

[0117] As the cover 1.10 is made of injected engineering plastic, it has fastening towers 1.10.7 prepared for said screws, as may be seen in FIG. 17.

[0118] Also attached to the cover 1.10 is a retainer 1.10.3 for each axis, in order to maximize the sealing of the outer lock, and prevent any dust or fluid from affecting the lock function. These retainers are fitted in a special slot designed on the cover 1.10 and are fastened by pressure caused by a plate 1.10.4 shaped according to the slot and fixed with three self-tapping 3.5 Phillips screws 1.10.5 directly to the cover 1.10. Between the assembly of the cover 1.10 and the base 1.1, with all components already mounted, a mantle 1.10.8 is placed, which may be seen in FIG. 4 of a sealing material so that any point that may end up with enough seepage space is sealed by this mantle 1.10.8, granting additional sealing points.

[0119] FIG. 8 shows the installation of the lock with the rest of the components. In each end of the lock axles 1 a nut is installed, called yoke nut 2.1, which is fixed by a M8 partial thread hex head screw 2.1.1, and this screw may be seen in the sectional FIG. 9 passing through the internal part. This nut remains loose until the connection with the rest of the extension axis.

[0120] The extension axis (lower 2.2 or upper 2.3) comprises three pieces. The first piece called threaded axis tip 2.2.1, the second piece called intermediate axis tube 2.2.2 and the last piece called chamfer axis end 2.2.3.

[0121] The design of these items was such as to allow for one-time installation of external lock peripherals, so that the lock 1 has a portability differential in relation to patent MU 8601581-8.

[0122] Therefore, the installation of components outside the lock 1 is done as follows: two sets of cables are laid, one set for feeding and another for activation of the safety switch, or more depending on the application. Afterwards, the structure that receives the lock must include a lock reinforcement plate 3 placed at an equivalent height to the locking point, fixed by rivets 3.1 around the plate. Then the lock 1 is fastened on this reinforcement plate 3 by five M8 customized safety screws 3.2 and a pressure washer. At the end of the lock 1 the yoke nuts 2.1 are fixed with their respective screws and then the extension axles are threaded.

[0123] In order to assemble the extension axis on lock 1, the threaded axis end 2.2.1 must be threaded to the yoke nut 2.1, then the intermediate axis tube 2.2.2 measurement is taken regarding the activation course, subtracting the measure of the chamfer axis end 2.2.3. With the intermediate axis tube 2.2.2 in the correct measure, a hole is drilled at the base of the tube near the axis and fixed using the tube on the threaded axis end 2.2.1 by a M8 hex head screw 2.2.4 with pressure nut and washer. The process is repeated for fixing the chamfer axis end 2.2.3 to the other end of the intermediate axis tube 2.2.2. This process is done both for the lower extension axis 2.2 and the upper extension axis 2.2 For safety reasons, after all intermediate tubes are fixed in both axis ends using all due screws, welding the nut and screws is recommended, thus avoiding undue disconnection. In order to maintain linearity and free movement of the axles, bearings 4 are placed throughout the length of the axles, ensuring the correct movement without forcing the system of the lock 1.

[0124] FIG. 9 shows a better picture of how the connection between the extension axles and the axles of the lock 1 is assembled.

[0125] Near each axis end, a locking ring 2.2.5 is attached by a M8 hex head screw 2.2.6 before the bearings 4 closest to the edges, to prevent the axis from slipping through the bearings and out of the alignment when lock 1 is disengaged.

[0126] With external components and lock 1 already fastened, the lock 1 may be exchanged or only removed simply or quickly. When unscrewing the yoke nut 2.1 the extension axles remain free, and when disconnecting the electric connectors of lock 1, the five screws that fasten the lock to the reinforcement plate 3 may be removed and the lock 1 may be removed, or replaced. This ensures increased agility and portability for application when the use of the lock 1 was a pre-set period, in other words, the service provider for trucks or container usage, its usage will be restricted to the period where the cargo is being transported to a certain client which usually will be the lock owner, object of this Invention patent application. The client may install the lock in locations (truck cargo boxes/containers) considered necessary, for a much more rational and smart use, reducing operational costs when compared to solutions currently used and known in the state of the art.

[0127] In order to protect this system, protection gutters 5 must be installed, ensuring no other cargo or other elements may damage the extension axles, as may be seen in FIG. 10 or 11 or even FIG. 12.

[0128] The locks and their accessories may be manufactured in several materials and finishes, such as standard 1020/1045 zinc-plated, bichromate or electrostatic painted steel. They may be manufactured in 304/316 stainless steel when needed for cooled locations, such as cargo box trucks or cold chamber trucks, when this lock type is needed, as it includes internal cooling and incidents may occur, therefore stainless steel is needed to prevent the locks from rusting.

[0129] A cementing or tempering layer may be applied to the axles, in order to generate additional difficulties in case of a robbery incident, making cutting more difficult using a saw or similar alternative, due to the fact that the external layer will be much harder than the internal layer, preventing any cutting by this kind of tool.

[0130] Hence, this lock addresses issues and limitations normally seen in more standard solutions already known in the state of the art.

[0131] Within the basic construction described above, the lock, object of this Invention patent application, may show modifications related to materials, dimensions, construction details and/or configurations without deviating from the scope of the requested patent protection.

DESCRIPTION OF OPERATION

[0132] The lock, object of this Invention patent application, was developed for use in access control restriction under authorization conditions.

[0133] An application example is in vehicles, where a set is installed on the doors for cargo access control. FIGS. 10, 11, 12 show this application example on a truck, a container and a van.

[0134] In this example, in order to disengage the lock, the user must employ a previously chosen and installed method for opening, for example, activation by tracker, or use of the Bluetooth/Wi-Fi module 1.5 developed by the Applicant, or another opening device. This way, the Bluetooth/Wi-Fi module 1.5 will receive the opening command and unlock the system.

[0135] In case of any power or electronic failure, the user must then employ a special safety switch 1.6.1, which will be connected to a specific point. This makes the connection with the contingency RS485 electronics 1.6, allowing the lock 1 to be opened and unlocking the system. In order for the safety opening switch 1.6.1 to work, safety information must be recorded in it, such as date and place and usage time, location and allocated user through a recording module 1.6.2 which is connected to the key via a cable.

[0136] For closing the set of doors, or door, as soon as the sensor detects closing (either one), the system acknowledges, in other words, the door must be closed for the sensor to work, the Bluetooth/Wi-Fi module 1.5 shall lock the system by lock 1. When the closing sensor fails, the contingency closing function is used, generating a password and a counter-password on the webservice 10.2 to close the lock 1.

[0137] If not closed, the technical assistance team must be called, to perform proper diagnostics and repairs to the lock assembly 1 that is object of this Invention patent application.

[0138] The Bluetooth/Wi-Fi module 1.5 was developed with a stand-alone and safe opening method for use in combination with the application for use 10. The application for use 10 works in two phases; in the first, a password is generated by a user in the same location as the assembly, since when accessing through the application 10.1, the mobile device connects via Bluetooth with the assembly and a password is generated by the application, which must be informed on the second phase.

[0139] In the second phase of the process the user must inform this password to a security center, which will validate this password with the geographical position of the user that requests the opening.

[0140] The user of the smartphone application 10.1 (for Android 4.0 operating system or higher) must insert username and password to access the device panel. With the device panel now open, the user then selects as desired, connects and opens. The device screen shows the “Door Closed” and “Lock Engaged” statuses, conforming the physical state of the assembly. When the password button is pressed, the application 10.1 shows a password with 24 alphanumerical characters, including: the requesting user, mobile phone IMEI number, date and time, and MAC address of the Bluetooth, latitude and longitude of the geographical position, in other words, a series of validations for ensuring the accurate information of the requesting person, where it is being requested to and which lock 1 to open. The user then informs the password to the security center.

[0141] The center validates the password sent by the application user, the center operator must insert the password in the webservice counter-password panel 10.2 (available for any operating system with Internet features), selecting the requesting user and the password informed. The web application10.2 then shows the password position and validation, and the assistant confirms the position found by the app, afterwards informing the counter-password for opening the assembly.

[0142] The user in the opening location must then insert the counter-password and press the button on the application 10.1 for opening, therefore the statuses on the panel must switch to “Lock Disengaged”, and at the time the door is opened, switch to “Door Open”, remaining as such until it is closed again.

[0143] This opening method is able to encompass all points, as it is not affected by blind spots (areas where GRPS signals are weak or nonexistent).

[0144] Another opening alternative through the application for use 10 developed by the Applicant consists in registering opening points on the cloud-hosted webservice 10.2, in which all points where the app (10.1) must perform the opening automatically are already defined (enabling the open button in authorized locations), not requiring the generation of passwords and counter-passwords to open, nor the intervention of a center for that purpose.

[0145] These points may be recorded manually in the webservice 10.2 and directly to the platform, uploading an electronic spreadsheet format file or by API, in which these points may be gathered directly from a client ERP software or similar, which presets all opening points (delivery locations/client addresses) allocated per vehicle (plate) and sent for allocation of this information to the smartphone app 10.1. As soon as the information is allocated on our webservice platform 10.2, the user already knows all delivery points (opening points) assigned for that vehicle equipped with the lock that is object of this Invention patent application when logging in to the smartphone application 10.1.
