Description

CASING FOR MOBILE ELECTRONIC DEVICE

TECHNICAL FIELD

The present invention relates to casings for mobile electronic devices in general, and in particular to casings to which commercially available standard batteries such as AA batteries can be connected in order to power the device.

BACKGROUND ART

Mobile electronic devices such as mobile phones, smart phones, tablets and laptops are common and useful tools in the life of the modern person. The smart phone is a vital tool for many people offering besides telephony services additional useful services such as email, personal contacts, calendar, navigation, access to the Internet and an abundance of standard and custom applications. As usage increases depletion of the battery becomes more rapid and many users are left without a working mobile device by the end of the day even when the device was fully charged when starting the day. In the future, the smart phone is envisioned to take an even more prominent role, for example, being your electronic wallet, key to your home or car, identification means etc.

As mobile electronic devices become more important to our daily lives, the question arises what happens when the device runs out of battery? Several solutions exist. Some people take with them a charger, but then one might not be near an electric socket, or have the time to wait while the phone is charging. Some people take with them an additional charged battery. But even a second battery can run out, and some devices, like Apple's (TM) products, do not allow the user remove the battery. There is thus an ever increasing need to keep mobile devices, and in particular mobile phones, charged in all circumstances. SUMMARY OF INVENTION

In the following detailed description of various embodiments, reference is made to the accompanying drawings which form a part thereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. The present invention relates to a casing for a mobile telephone. The casing is a protective or non-protective casing that at least partially covers the mobile telephone, for example, covering the back and the sides (but not the front). The casing can have different openings to fit the mobile phone buttons, camera etc.

The casing of the invention has an auxiliary power supply unit integrated into it. The auxiliary power supply of the casing comprises four components:

a) A mechanical arrangement for securely holding one or more batteries, such as of the type AA, AAA, AAAA, D, C or 9-volt. The objective is to integrate commercial batteries (typically disposable batteries) that the user can purchase at any point of sale (kiosk, grocery store etc.), as opposed to integrating a rechargeable battery such as the one which comes with the mobile phone or device. Carrying a second battery all the time (such as lithium-based batteries that come with a mobile phone) can be a good solution for a user who plans in advance and always charges his second battery. The casing of the invention comes in handy when the user's battery is depleted before the user has an opportunity to recharge the phone, and the user can then buy disposable batteries at any point of sale in order to continue to use his phone. The invention is also very helpful, for example, when going camping in the mountains for several days or in cases when there is no electricity in a region for a prolonged period of time.

b) The auxiliary power supply has at least one positive electric connector and at least one negative electric connector in order to connect to one or more batteries. The number of batteries to connect is determined by the power consumption of the mobile phone or device and the voltage of the battery or batteries to be used. The invention encompasses using one or more batteries.

c) The auxiliary power supply also has an electronic circuit connected to the at least one positive electric connector and to the at least one negative electric connector, for converting the voltage supplied by the battery or batteries to a voltage level suitable for powering the mobile telephone or device; and

d) Finally, the auxiliary power supply also has an electric plug or electric connector connected to the electronic circuit. The electric plug's end or the electric connector are made in a form to fit the power input of the mobile telephone (same form as the mobile's phone charger). When the one or more batteries are connected to the electric connectors and the electric plug or electric connector are placed into the power input (power socket) of the mobile telephone, the mobile telephone can be operated with the power of the one or more batteries.

The voltage supplied by the purchased batteries may not be directly suitable to power the mobile the phone. In these cases, an electronic circuit is connected to the positive and negative electric contacts, for converting the voltage supplied by the supplied batteries to a voltage level suitable for powering the mobile electronics device

Reference is now made to the attached drawings that should be interpreted as representing, merely, some embodiments of the invention, while many other embodiments exist that are covered by the present invention. For example, for simplicity's sake, the drawings refer to a casing of the invention for a mobile telephone, while the casing of the invention can apply to any mobile electronic device such as a tablet, a notebook computer, a portable game console etc.

Fig. 1 shows an embodiment of a two-part casing according to the invention, with the lower part 60 past sliding over the lower end of the upper part 65. In use, the mobile electronic device, in this case a mobile telephone, is inserted in the upper part 65, and the lower part 60 is pushed up until it closes over the bottom of the mobile telephone.

The casing of the invention can be made from different materials including rigid, semi-rigid or elastic materials, for example, metal, plastic or composite materials.

Fig. 2A illustrates how the lower part 60 casing of Fig. 1 can slide up and down. Fig. 2B illustrates an embodiment where the commercially available battery 70 is inserted. The supplied battery 70 can be held using a variety of mechanical embodiments, all of them encompassed by the current invention.

When the mobile telephone runs out of power, or when necessary, the lower part 60 is pulled down as shown by the arrow in Fig. 2A, exposing a battery compartment, as shown in Fig. IB, in which one or more batteries 70 can be inserted. The battery 70 or batteries 70 are inserted by connecting the battery's 70 positive connector to the casing's positive connector and connecting the battery's 70 negative connector to the casing's negative connector. The power connector is pulled out from its storage place in the case and inserted in the phone charging socket, and then the lower part is pushed up all the way to lock the battery 70 in place (although it may still be visible from the front of the case).

The lower part 60 can be positioned and locked in three different states (positions):

Closed with phone inside (no battery 70 present);

Closed over an inserted battery 70; and

Open to accept a battery 70. The last locking position is to prevent the lower part 60 from sliding off the upper part 65.

Locking can be accomplished with any locking means of the art, including but not limited to magnets or spring latches.

Fig. 3 shows the inside part of an embodiment of a casing of the invention, showing the auxiliary power supply unit, the power connector and the expandable shell for inserting a battery 70.

The auxiliary power supply unit comprises a power convertor 10 for converting the voltage provided by the battery 70 or batteries 70 to the voltage level required by the mobile phone. In this example, the 1.5V of the battery 70 is converted to 5V, the voltage required by the mobile phone as presently designed and powered.

The battery 70 is inserted by connecting the battery's 70 positive connector to the casing's positive connector 20 and connecting the battery's 70 negative connector to the casing's negative connector 21.

Two folding "wings" 30 carry the battery 70 contacts 20 and 21. The wings 30 rotate down and out on the hinges to create the space for the battery 70 in this embodiment. The wings 30 swing into place on hinges when the battery 70 is pushed from the top. A thick elastic panel 40 is embedded in the mold as part of the back of the case.

The electric plug 50 is connected to the electronic circuit. The electric plug 50 is made in a form in which one end fits the power input of the mobile telephone (not shown). When necessary, the electric plug 50 is removed from its storage position in the casing and plugged into the telephone's power input.

Fig. 4 shows the back view of the casing of Fig. 3 when no battery 70 is inserted. The elastic panel 40 forms a smooth back face merging with the rest of the back of the case.

Fig. 5 shows the back view of the casing of Fig. 3 when a battery 70 is inserted.

The two wings 30 lock the battery in place, and their shape appear as a rounded "bump" on the back of the case.

The electric plug 50 is taken out of its storage position inside the case, and plugged in the telephone's power input at the bottom of the device.

In some embodiments, the use of an electric plug 50 can be avoided by instead having power connector (not shown) integrated into the lower part 60 of the casing and thus plug right into the mobile device's power entrance.

Figs. 6A-6C shows an embodiment of a casing of the invention. Fig. 6A shows the casing where the two hinges 80 for accepting a battery 70 are in a closed position and no battery 70 is inserted. Fig. 6B shows the two hinges 80 in an open position, ready to accept a battery 70. Fig. 6C shows the two hinges 80 closed with a battery 70 inserted in between.

Figs. 7A-7E shows an embodiment of a casing of the invention. Fig. 7A shows the casing where the battery cover 75 is closed position and no battery 70 is inserted. Figs. 7B-C shows the battery cover 75 in an open position, ready to accept a battery 70. Fig. 7D shows the battery cover 75 open with a battery 70 inserted inside. Fig. 7E shows the battery cover 75 closed with a battery 70 inserted inside.

Fig. 8 shows an embodiment of a casing according to the invention comprising two hinges 80 for holding a battery 70. The hinges 80 are positioned on the back cover and can, for the sake of convenience of the user, fold into the cover when not in use. One hinge 80 holds the positive connector 20 and one hinge 80 holds the negative connector 21.

In another aspect, the present invention relates to a charger for a mobile device to which is coupled an auxiliary power supply unit of the invention. When the user needs to recharge his mobile device, and the user cannot connect the charger to an electric outlet, one or more batteries 70 can be connected to the charger, and thus the charger can be used to charge the mobile device. This solution is very practical when the user is not by an electric outlet, or in cases where the user is on the move and thus cannot wait by an electric outlet to charge his mobile device.

Fig. 9 shows an embodiment of a charger 90 of a mobile device according to the invention with a mechanical arrangement for a holding a battery 70. The invention, as described above, can be used to secure one or more batteries 70 to a charger 90 of a mobile electronic device such that the mobile electronic device can be powered by the charger 90 when the battery 70 or batteries 70 are connected to the charger 90.

Fig. 10 shows an embodiment of a charger 90 of a mobile device with a coupled battery 70. Plugging the electric plug 50 now to the mobile device will charge the mobile device.

Reference is now made to Fig. 11 showing an embodiment of a two-part casing according to the invention (only lower part 60 shown), with the lower part 60 made to slide over the lower end of the upper part 65. The lower part 60 shows an integrated power connector 55. The power connector is 55 attached to the casing and to the electric circuit connected to the one or more commercially available batteries 70. The power connector is 55 is made to fit the power entry of the mobile device and thus can charge the mobile device when one or more batteries 70 are connected. Preferably, the connector is 55 has a cavity on the other side (not shown) such that a user can plug a regular charger into the mobile device, through the power connector 55. The power connector is 55 is an alternative to the power plug 50.

Fig. 12 shows the lower part 60 casing of Fig. 11 wherein a battery 70 is connected, along with the upper part 65 of the casing.
