[0022] Embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which:

[0024] FIG. 2 is a perspective schematic view of a second container embodiment, in which the container includes a door that is self-closing due to a spring.

DETAILED DESCRIPTION OF THE DRAWINGS

[0026] Turning now to FIG. 1A, it shows a perspective view of a container 100 embodiment including a self-closing door 110. In the situation being shown, a mobile device 900 is recharging inside the container 100. For illustrative purposes, the internal components of the container 100 are not shown in FIG. 1A.

[0027] Although the mobile device 900 shown in FIG. 1A resembles a tablet or a smartphone, the mobile device 900 may be any item including a rechargeable battery, such as a laptop, a flashlight, a wireless power tool, or a rechargeable battery itself. The container 100 may be implemented with different sizes and forms so that different items may be placed inside the container 100.

[0028] The user of the mobile device 900 can leave the latter recharging inside the container 100 without having to be aware or awake and to monitor if the recharging operation is happening safely without starting a fire. The device is directly accessible while the recharging operation is taking place, as is observable in FIG. 1A.

[0029] When a safety event, such as a fire, is detected inside the container, the door 110 will close the container in a descending vertical movement, as shown by the arrow in FIG. 1A. The container 100 is made of material suitable for heat and small fire. Thus, the fire will be enclosed in the container 100 and its risk of propagation will be efficiently attacked at its early stages.

[0030] FIG. 1B shows an elevation view of the container 100 shown in FIG. 1A. Both the mobile device 900 and the charger 910 are shown inside the container 100. In addition to the self-closing door 110, the container 100 includes a sensor 120 for detecting a fire inside the container 100 and an actuator 130 for retaining the door 110 in the open position (as shown in FIG. 1B).

[0031] The sensor 120 is positioned on the ceiling of the interior of the container 100, above where electronic equipment, such as the mobile device 900, is expected to be recharging. It is also suitable to have the sensor in any other position that allows detecting fire in the interior of the container 100. If any safety event happens, such as the mobile device 900 or the charger 910 starting a fire, the sensor 120 will detect it.

[0032] Several options may be chosen for implementing the sensor 120, such as a heat sensor, fire sensor, or a flame sensor.

[0033] The door 110 is retained in the open position by the actuator 130. One option for implementing the actuator 130 is to use a magnetic actuator that produces a magnetic force in a portion of the door 110 and will thus keep the door fixed in the open position. Another option is for the actuator 130 to grip the surface of the door 110 with an appropriate contact surface.

[0034] When the sensor 120 detects a safety event, the power signal of the actuator will be switched off so that the door 110 is released. This reacting control of the actuator 130 may be implemented in many manners known by a skilled person.

[0035] FIG. 1C shows a schematic elevation view of the container 100 embodiment including some additional components: three charging points 911, 912, 913 are shown inside the container 100; and the sensor 121 includes a wireless communication module 140. Also shown is a schematic of the electric circuit that powers the three charging points 911, 912, 913 and the actuator 130 for retaining the door. This schematic also includes a representation of the power source 142 from which electric power is drawn and a wireless circuit break 141 for switching the power source 142 on or off.

[0036] The three charging points include a mains socket 911, a USB female socket 912, and a wireless charger 913. Also, the actuator 130 is powered to the same electric circuit of the charging points 911, 912, 913. This enables a global fail-safe capability, in which the switching off of the power supply applies directly to all the charging points 911, 912, 913 and also the actuator 130.

[0037] When the sensor 121 detects a fire, the wireless communication module 140 is used for communicating this to the wireless circuit breaker 141. This communication can be implemented with a Wireless Z-wave signal platform with 868.4 MHz RF (908.4 MHz USA/Canada), for example. The wireless circuit breaker 141 therefore cuts the power being supplied to the container 100. This achieves an improved actuation when a fire is detected, as switching off the power supply of the container results in both the charging points 911, 912, 913 being switched off as well as the door 110 closing. Therefore, and improved efficiency is achieved in attacking a fire in its early stages.

[0038] FIG. 2 shows a perspective view of a second container 101 embodiment, in which the container 101 includes a door 111 that is self-closing due to a spring (not shown). The container 101 has a cylindrical form and the door 111 closes in a horizontal motion similar to the motion of a curtain closing.

[0039] For illustrative purposes, the container 101 is shown from a global point of view from the outside and both the actuator and the sensor are not shown. The actuator is positioned on the inside of the container and operates to retain the door 111 in the open position shown in FIG. 2. The sensor is on a portion of the interior of the container 101 that is suitable for detecting fire from a mobile device recharging inside the container 101. For example, the sensor may be positioned on the ceiling or upper part of the interior of the container 101. The cylindrical form in combination with the position of the sensor on the upper part of the interior of the container 101 provides an improved detection of fire or any other safety events inside the container, as the sensor can thus perform isotropic measurements.

[0040] The container 101 also includes an audio alarm 160 at the top, which produces an audible sound when a fire is detected by the sensor. This is increases the container's safety in fighting fire, as it will give its user a warning that a safety event has been detected.

[0041] Moreover, the container 101 includes a wireless communication module 140 similar to the one shown in FIG. 1C, although in this case the wireless communication module 140 is further used to communicate with a fire alarm system, which may have further configurations to immediately issue an emergency request to the emergency services or the local fire department.

[0042] In FIG. 3, an elevation view of a third container 102 embodiment is shown. The container 102 includes two compartments: a first compartment is shown on the centre and right half of FIG. 3, and it includes a housing for positioning a mobile device 900 to be recharged; a second compartment is shown on the lower portion of the left half of FIG. 3, in which a fire extinguisher 170 is shown.

[0043] The first compartment includes a self-closing door 112 that self-closes in a semi-circular sliding motion on the first compartment (see arrow near the door 112 in FIG. 3). The door 112 is self-closing due gravity and a spring 150. This combination produces an efficient closing movement, and this gives an improved action to close the interior of the container and stop any mobile device or charger fire from evolving into a stronger fire.

[0044] The second compartment includes the fire extinguisher 170 for further increasing the extinguishing actuation in the first compartment when a fire is detected by sensor 120. The first and second compartments are connected by a channel that enables the fire extinguisher 170 to dispense an extinguishing agent into the first compartment, such as foam or CO.sub.2.
