The present application claims priority to U.S. Provisional Patent Applications 61/544,194, filed Oct. 6, 2011, entitled “Smart Phone Charger System,” and to 61/605,118, filed Feb. 29, 2012, entitled “Smart Phone and/or Consumer Electronics Device Charger System,” for which both applications are incorporated herein by reference in their entirety.
TECHNICAL FIELDThe present invention relates to chargers for electronic devices such as smart phones (including iPhones™, iPads™, etc.), and also to chargers for other consumer electronics devices.
BACKGROUND OF THE INVENTIONPeople rely more and more on their smart phones and these devices are being used for more and more hours of the day. Unfortunately, smart phones tend to be “battery hogs” that consume a significant amount of energy. In many regards, the biggest limitation to these devices is their (relatively short) battery life. They all typically require a daily charging.
Numerous charging devices already exist for phones and smart phones. Typically, these charging devices include standard plug-in wall cords, and/or power cords that plug into computer USB ports. Many users do not find it convenient to rely on these long charging cables. It's inconvenient to carry them around, and it's also inconvenient to always have to return your smart phone to the same spot to charge it up at the end of the day. Therefore, other solutions on the market include battery packs that fasten directly onto the phone or are connected to the phone by a short plug in cable. The main problem with these devices is their added bulk and weight.
An example of a charging device for a consumer electronics product is found in U.S. Pat. No. 7,938,653. This device is simply a folding plug at the end of a charging cord. The plug has a pair of plug blades that fold down one on top of the other. The blades rotate in the same direction as they are deployed. This blade folding arrangement unfortunately requires a deep trough into which both blades are folded (one sitting on top of another). In addition, this trough extends fully out the side of the device such that the user must insert their finger and pull upwardly on one of the blades, thereby causing both blades to rotate into position. A primary disadvantage of this system is that the two blades are folded one on top of another. This requires a deep channel/trough into which both blades must be folded. Another disadvantage of this system is that this channel/trough must extend fully out of the side of the device. In addition, one of the blades must have its tip positioned near the end of the channel/trough at the side of the device such that the user's fingers can grip onto it. As a result, the position of the two blades is effectively fixed with respect to the sides of the device.
It would instead be desirable to overcome the limitations of the '653 patent's folding plug blades. For example, it would be desirable to provide a plug that can be stored without requiring a deep channel into which two blades are folded one on top of one another. It would also be desirable to provide a system in which the user does not have to grasp onto the ends of one of the blades to deploy them. Instead, it would be desirable to provide a system in which the blades automatically deploy at the push of a button under the user's command. It would also be desirable to provide a system in which the blades can be centrally located on the back of the device being charged if desired. Lastly, it would be desirable to completely avoid the charging cord itself, for example when charging an iPhone™ or other smart phone.
What is instead desired when charging smart phones in particular is a system that uses standard wall power AC outlets, but also avoids the use of a large, bulky extra battery pack. It is also desirable for such a system to completely avoid the use of long power cables running from a charger to the device being charged.
SUMMARY OF THE INVENTIONThe present invention provides a charging device having a pair of rotatable blades or pins. The blades are rotatable from a deployed position in which ends of the blades are inserted into a standard AC wall outlet to a retracted position in which the ends of the blades are spread apart from one another and lie flat against the charger to decrease the overall thickness of the charger.
The most important advantage of the present invention is that it reduces the overall thickness of the charger itself. Specifically, the plug-in blades are rotated from the parallel orientation (i.e.: in which they are inserted in a standard wall outlet) down to a flattened orientation in which they are instead positioned in the same plane.
In various embodiments, the present rotatable plug charger is built into (or onto) the body of the smart phone. Alternatively, it may be a separate device that is connected onto the back or bottom of the smart phone. As will be shown, however, the present folding blade charging device can also be used with other suitable consumer electronics devices (for example, battery rechargers, electric toothbrushes, shavers, etc.). In further embodiments, it may be a separate device that is attached by a short cable to the smart phone.
As can be seen in
The present invention provides various systems for moving blades 32 between retracted and deployed positions. In one example, blades 32 may be mounted onto a spring (or otherwise) biased rotatable member 33. Thus, members 33 simply rotate by 90 degrees (or approximately 90 degrees) to move blades 32 between retracted and deployed positions. Various mechanisms 34 for activating movement of members 33 will be described herein.
In various preferred embodiments, blades 32 are geared together such that have to work in unison. In such embodiments, a user simply depressing one blade 32 will cause the other blade 32 to move as well. This embodiment is especially convenient such that the user does not need to hold down both blades 32 to push them into a retracted position.
In yet another preferred embodiment, the charging circuit is not activated until both blades 32 are deployed. With this safety feature, there is no danger that the charging circuit can be turned on until both blades are firmly in their deployed position.
For example,
In another approach,
It is to be understood that other options for rotating blades 32 between their retracted and deployed positions are also possible. For example, blades 32 need not be biased. Instead, they may be simply rotated by manually turning a wheel or lever. They may also simply be manually rotated by a user individually grasping onto the blades one by one and rotating them into position. Alternatively, the blades can be geared together such that movement of one causes the other to move (this has the advantage that only one blade needs to be depressed to move both blades into their retracted position). It is also to be understood that the various mechanisms described herein may be used to rotate blades 32 together or individually. A “click down to release” biasing option is also available, as will be explained below.
After use (i.e.: when the blades 32 are removed from the wall outlet), the user simply depresses blades 32 to their retracted position. At this time, biasing spring 60 will slide forward extension 61 back into slot 64 thereby holding the blades back in their retracted position. One particular advantage of this system is that only a simple one finger push and slide of switch 38 is required for blades 32 to be automatically deployed. The user does not have to grab onto the blades and pull them out to deploy them. Thus, there is no need for a blade slot that reaches the side of the device. Instead, the tips of blades 32 can be positioned away from the edges of the device when they are in their retracted position. Moreover, the user's finger moves in direction D1 (i.e.: away from the deploying blades) as the blades deploy. Thus, there is no danger of the blades springing out and hitting the user's fingers. Advantageously as well, there is no need with the present invention for one blade to be folded on top of the other. Instead, each can be separately received in its own shallow receptacle on the back of the phone when they are in their retracted position. This advantageously minimizes the depth/thickness of the overall device.
