[0026] Referring to FIGS. 1-14, novel magnetically connected powering devices, apparatuses, and methods for powering electronic devices are discussed herein. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.

[0027] The present disclosure is to be considered as an exemplification of the invention, and is not intended to limit the invention to the specific embodiments illustrated by the figures or description below.

[0028] As shown in FIGS. 1 and 2, an example magnetic charging assembly 100 includes an insert 160 and first and second adapters 120, 140. The insert 160 includes a plurality of pin receiving cavities 162 on a front, outer surface 164 for receiving a plug of a device. During use, the pin receiving cavities 162 of the insert 160 receive an adapter 120, 140 is configured to connect thereto. Each adapter 120, 140 includes type A or B openings 122, 142 on a front, outer surface 124, 144 thereof as well as electrically conductive pins 126, 146 on a back surface 128, 148 thereof. The type A or B openings 122, 142 on the front of the adapter 120, 140 allow for insertion of plugs of devices to be powered and a place for the current to flow. The pins 126, 146 on the back surface allow for mating with the pin receiving cavities 162 of the insert 160. The insert 160 is connected to voltage sources, such as the wall socket. In the embodiment illustrated in FIG. 2, the insert 160 includes plugs 166 for inserting into a wall socket. In the illustrated embodiment, the insert 160 is configured to receive two adapters 120, 140. In other embodiments, the insert 160 may be designed to receive one adapter or more than two adapters.

[0029] FIG. 3 shows example widths of one embodiment of the insert 160 and adapters 120, 140. The illustrated proportions of the components are exemplary only and may be modified as needed.

[0030] As shown in FIGS. 1-3, the back surface 128, 148 of each adapter 120, 140 and the corresponding portion 168a, 168b of the front surface 164 of the insert 160 have mating curved surfaces that facilitate the connection of the adapter 120, 140 to the insert 160 in the correct orientation. The insert 160 has a concave section while the adapters 120, 140 have a convex section that fits into the respective portions 168a, 168b of the insert 160. The curves are designed specifically to only allow one orientation for connection. In one embodiment, the curves' bases have a non-symmetrical geometry so that they can only be fitted in the correct y-axis orientation.

[0031] Additionally, the intensity of the curve's height has been tested to allow for maximum stability in both the x and y directions without excessive height or inhibiting the disconnection of the two parts when an appropriate force is applied. In combination with the magnets described below, the curves allow for the connection of the insert 160 and the adapter 120, 140 to be as stable as possible.

[0032] Referring to FIGS. 1 and 2, the back surface 128, 148 of each adapter 120, 140 includes three pins 126, 146 that mate with corresponding pin receiving cavities 162 in the front surface 164 of the insert 160 within the corresponding curved portions 168a, 168b. The pins 126, 146 bridge the energy connection between the adapter and the insert. The positioning of the pins 126, 146 corresponds to the positioning of type B prongs. The pins 126, 146 may be any conductive element that allows for a solid connection. When the insert 160 and the adapters 120, 140 are mated, the pins 126, 146 align to allow the two electrical circuits to connect, and the current from some source to flow through both the insert 160 and the adapters 120, 140 to the devices needing power.

[0033] The elements of the magnetic charging assembly 100 are configured to combine into one succinct product that covers both sockets on an US plug type B wall outlet. This is to protect from any opportunity to receive live voltage and/or current from the outlet itself. The adapters 120, 140 are designed to detach easily from the insert 160 when a sufficient pulling force is applied without grabbing onto any of the components of the insert 160. Additionally, it is important to note that the adapter 120, 140 should not be placed on the insert 160 without the desired device to be powered plugged into it. An exposed adapter 120, 140 would leave an unprotected outlet and ultimately withhold the device from offering the same safety measures.

[0034] In the illustrated embodiment, the adapters 120, 140 are secured in place onto the insert 160 through the use of magnets 180, 200. In each adapter 120, 140, a first set of magnets 180 are mounted against the back surface of the adapter 120, 140 within an inner volume thereof as shown in FIGS. 4A, 4B, and 5. Within the adapter 120, 140, the pins 126, 146 are mounted onto a circuit board 130, 150 that contacts the plug of the respective device once plugged into the adapter.

[0035] Referring to FIGS. 6A-7B, a corresponding set of magnets 200 are mounted against the front surface of the insert 160 within an inner volume thereof. During use, the first set of magnets 180 in the adapter 120, 140 are attracted to the second set of magnets 200 within the insert 160. The magnets 180, 200 create a stable hold while still allowing for the connection to be easily broken given a sufficient amount of force.

[0036] Within the insert 160, the second set of magnets 200 is mounted onto an internal spring-loaded cover plate 220 that moves between a disconnected position (FIG. 7A) and a connected position (FIG. 7B). Referring to FIGS. 6A and 6B, the internal spring-loaded cover plate 220 has curved shape that corresponds to and mates with the curvature of the front surface 164 of the insert 160. The internal spring-loaded cover plate 220 includes a central cylindrical portion 222 that receives a protruding member 168 extending inwardly from the front surface of the insert 160 (see FIGS. 6C, 7A, and 7B) such that the spring-loaded cover plate 220 can rotate about the protruding member 168 between the disconnected and connected positions.

[0037] The second set of magnets 200 of the insert 160 is mounted to the internal spring-loaded cover plate 220, and a plurality of openings 224 of the plate 220 is provided and configured to allow the pins 126, 146 of the adapter 120, 140 to pass therethrough and into the pin receiving cavities 162 of the insert 160 when the adapter 120, 140 is connected to the insert 160. When the internal spring-loaded cover plate 220 is in the connected position, the first and second sets of magnets 180, 200 are engaged and attracted to one another and the plurality of openings 224 is aligned with the corresponding pins 126, 146 of the adjacent adapter 120, 140 and the pin receiving cavities 162 of the insert 160.

[0038] A spring mechanism 226 connects the internal spring-loaded cover plate 220 to the protruding member 168 of the insert 160 and biases the internal spring-loaded cover plate 220 into the disconnected position. In the disconnected position, the plurality of openings 224 of the plate 220 is not aligned with the corresponding pins 126, 146 of the adjacent adapter 120, 140 and/or the pin receiving cavities 162 of the insert 160 such that the plate 220 blocks anything from entering the pin receiving cavities 162. The barrier mechanism 220 therefore blocks objects, such as small fingers and metallic materials such as paper clips and eating utensils, and other items, from being inserted into the electrically-conductive pin receiving cavities. In some embodiments, the spring mechanism is a torsion spring, although any suitable biasing component may be used.

[0039] During use, the first and second sets of magnets enable the internal spring-loaded cover plate 220 to rotate and allow the adapter 120, 140 to be plugged into the insert 160. When the internal spring-loaded cover plate 220 is in the disconnected position, the second set of magnets 200 attached to the internal spring-loaded cover plate 220 in insert 160 is offset from the positioning needed to engage the first set of magnets 180 on adapter 120, 140 during use. When the adapter 120, 140 is brought near the insert 160, the first set of magnets 180 in the adapter 120, 140 causes the plate 220 to rotate against the bias of the spring mechanism 226 to bring the second set of magnets 200 toward and aligned with the first set of magnets 180. This movement causes the plurality of openings 224 in the internal spring-loaded cover plate 200 to align with the pin receiving cavities 162 of the insert 160, allowing the pins 126, 146 of the adapter 120, 140 to pass through the spring-loaded cover plate 220 and into the pin receiving cavities 162. The cover plate 222 also includes stop features 228 to limit rotation of the cover plate 222 about the protruding member 168 of the insert 160 between and not beyond the disconnected and connected positions.

[0040] The internal barrier mechanism 220 is embedded into the device to protect from live voltage and/or current when the adapter 120, 140 is not connected by covering the live pin receiving cavities 162. In another embodiment shown in FIGS. 10 and 11, a simple spring loaded barrier system positions a cover 300 over the pin receiving cavity 162 while the adapter 120, 140 is disengaged.

[0041] As shown in FIG. 10, the cover 300 is biased into place by a spring mechanism 302 and moves laterally toward a side surface of the insert 160 as the adapter 120, 140 moves into place, with the pin 126, 146 pushing the cover 300 to the side. In this embodiment, the spring loaded barrier system covers 300 only the pin receiving cavity 162 that carries the live voltage and/or current, as the other two pin receiving cavities 162 do not carry live voltage and/or current and are therefore not a safety concern.

[0042] The cover 300 is designed to ensure that only the pins 126, 146 can push the barrier or cover to the side and that other objects that commonly fit into electrical sockets cannot do so. Specifically, as shown in FIG. 11, the cover 300 has a slanted geometry that allows the pins 126, 146 of the adapter 120, 140 to release the cover while sharp objects, such as a fork, cannot gain enough leverage to do so. Larger objects, such as a finger, that are not specifically designed for the space are unable to gain enough force within the small area to push the cover back. The cover's edges, when deployed, are hidden within the housing of the insert 160 and cannot be used to grip and push the latch back as well. All these features have been tested to ensure the overall safety of the device.

[0043] Referring to the embodiment shown in FIGS. 6A and 6B, the openings 224 of the spring-loaded cover plate 222 configured to receive the pins 126, 146 also includes a slanted geometry to allow the pins 126, 146 of the adapter 120, 140 to cause the plate 222 to rotate and allow the pins 126, 146 to enter the pin receiving cavities 162 of the insert 160.

[0044] Referring to the embodiment illustrated in FIG. 1, a screw is provided within the insert 160 to secure the insert 160 onto a standard wall outlet. The screw is an optional addition to the magnetic charging device assembly 100, making it virtually impossible to remove the insert 160 without unscrewing it. Thus, screwing the insert 160 on a wall outlet is not necessary for the functionality of the device but exists should a user want to ensure near-permanent security of insert 160 onto the wall outlet.

[0045] An alternate version of the magnetic charging assembly is shown in FIGS. 12, 13, and 14. FIG. 12 illustrates an alternate embodiment of the device that embeds itself directly into the wall. In this version, the adapters 120, 140 of the assembly 100 remain unchanged, as does the overall functionality. The insert 160 of this embodiment replaces the standard wall outlet in its entirety instead of needing to plug insert 160 into the wall outlet. The wall insert 160 provides the desired functionality by housing the magnets and pins. A wall cover surrounds the wall insert 160 and contains the insert 160 to the wall and contributes to the overall aesthetic of the device. The modified insert 160 can be best seen in FIG. 13 prior to it being embedded into the wall. The electrical inputs to the insert 16 also stay consistent with that of a common wall outlet and can be seen in FIG. 14.

[0046] While preferred materials for elements have been described, the device is not limited by these materials. Wood, plastic, rubber, foam, metal alloys, aluminum, and other materials may comprise some or all of the elements of the device in various embodiments of the present invention.

[0047] Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar function and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present invention and are contemplated thereby.
