DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the drawings, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
In accordance with one embodiment of the present disclosure, FIG. 1 depicts an isometric view of select components of an example charging device 100, and FIG. 2 depicts a top view of the select components of the example charging device 100. As depicted in FIGS. 1 and 2, the charging device 100 includes a base 110, which in some embodiments is made from a molded polymeric material. Although the base 110 is depicted as being circular in FIG. 1, other bases of other charging devices in other embodiments may be differently shaped.
The base 110 includes at least one aperture 105a with an electrical connector 104 protruding therefrom. The electrical connector 104 may be a male plug, such as a Universal Serial Bus (USB) Type A, Type B, Mini-A, Mini-B, Micro-A, Micro-B, or any other male plug now known or later developed. Electrical connector 104 is generally configured to couple to an electronic device, such as a cell phone or tablet computer.
Surrounding the aperture may be an illuminable ring 106, which in some embodiments is made from a substantially transparent polymeric material. For example, as discussed further herein, in some embodiments, the charging device 100 may include one or more arrays of one or more light emitting diodes (LEDs) positioned within the base. The LED array may emit light though the ring 106, thereby illuminating the ring 106.
As further depicted, the charging device 100 also includes a rotatable top piece 101 positioned within the base. The top piece has pressure clips 102 that enable the top piece 101 and the base to receive a removable insert. Generally, a removable insert (as described further herein with respect to FIG. 6) fits into the negative space defined by top piece 101 and is secured by the clips 102. The top piece 101 may also include a release button 103, which when depressed manipulates at least one of the clips 102 such that the removable insert positioned in the negative space defined by top piece 101 may be removed.
FIG. 3 depicts a front view of the charging device 100, in accordance with one embodiment. This view depicts the base 100, release button 103 of the top piece 101, electrical connector 104, aperture 105a, and illuminable ring 106. In some embodiments, the aperture 105a includes a socket that enables the electrical connector 104 to be rotatably mounted within the base 110. In this way, the electrical connector 104 may be rotated up to 360° in order to match the configuration of a corresponding electrical receptacle on an electrical device, such as a cell phone or tablet computer.
FIG. 4 depicts a rear view of the charging device 100, in accordance with one embodiment. This view depicts the base 110, top piece 101, and second electrical connector 107. The electrical connector 107 may be a female receptacle configured to receive a corresponding male plug, such as a Universal Serial Bus (USB) Type A, Type B, Mini-A, Mini-B, Micro-A, Micro-B, or any other type of male plug now known or later developed. In practice, the electrical connector 107 may receive a cable that is coupled to an electrical power source, such as a wall receptacle.
FIG. 5 depicts a side view of the charging device 100, in accordance with one embodiment. This view depicts the base 110, top piece 101, release button 103, and electrical connector 104. As depicted, the electrical connector 104 (e.g., a male plug) is protruded slightly from the base 110 so that the electrical connector 104 may be received by a corresponding female receptacle on an external device, such as a cell phone or tablet computer.
FIG. 6 depicts an exploded view of several component pieces 600 that may be included with charging device 100, in accordance with one embodiment. As depicted, the component pieces 600 include a removable insert 108, a top piece 101 with pressure clips 102 and vertical clips 109, a base 110, and an optional annular ring 111 Generally, the removable insert 108 may be made from a molded polymeric material and have a substantially opaque portion and a substantially transparent portion. For example, as depicted in FIG. 6, the substantially transparent portion of removable insert 108 is a cut-out of the insert in the shape of crescent moon, whereas the substantially opaque portion is the remainder of the removable insert 108. Notably, in other embodiments, other cut-out shapes and other arrangements of transparent and opaque portions of a removable insert are possible. The substantially transparent portion may consist of the same material as the substantially opaque portion, a different material than the substantially opaque portion, or it may be negative space of the removable insert 108.
As depicted, the base 110 has a cavity, in which the electrical connector 104, electrical connector 107, LEDs (FIG. 10) and other power electronics (FIG. 10) reside. Base 110 is also depicted as having a groove 113 for receiving the vertical clips 109 of the top piece 101.
The charging device 100 may also include a rotatable annular ring 111, which may be mounted on the base 110 via any suitable mounting apparatus. For example, the annular ring 111 may be a cylindrical ring captured by circumferential protrusions on the base 110, or the annular ring 111 may include circumferential protrusions that capture the base 110. As depicted in FIG. 6, the annular ring 111 includes an aperture 105b and a groove 120 for receiving the vertical clips 109 of the top piece 101. In embodiments in which the base 110 includes more than one electrical connector, the annular ring 111 may be rotatable about the base 110 in order to selectively reveal the desired electrical connector through the aperture 105b. 
As further depicted, the top piece 101 is configured to releasably receive the removable insert 108 via the pressure clips 102. In practice, when the top piece 101 and removable insert 108 are positioned on the base 110, light emitted from LEDs positioned in the base 110 may be emitted through the substantially transparent portion of the removable insert 108. Further, the top piece 101 also includes vertical clips 109 in order to couple the top piece to the base and/or an annular ring that may be positioned about the base, such as annular ring 111. In some embodiments, the top piece 101 can rotate 360° within the base 110, and in further embodiments lock at 90° increments. In other embodiments, other configurations of top piece 101 are possible as well.
FIGS. 7 and 8 depict the rotation of the annular ring 111 about the base 110, in accordance with one embodiment. In particular, FIG. 7 depicts the base 110 with the annular ring 111 positioned so as to reveal electrical connector 104 through apertures 105a and 105b. As depicted, in this embodiment, the electrical connector 104 is recessed within the base 110. This allows for the rotation of the annular ring 111 without hindrance from the electrical connector 104. When it is desired to couple electrical connector 104 to an external device, the electrical connector 104 may protrude from the apertures 105a and 105b. For example, when the annular ring 111 is rotated to reveal the electrical connector 104 through aperture 105b, a spring within the base 100 may cause the electrical connector 104 to move from its recessed position within the base 110 to a position where it protrudes from the aperture 105b. And when it is desired to rotate the annular ring 111 in order to reveal another electrical connector, the electrical connector 104 may be manipulated to retreat into the base 110, such as by pushing it in. Other configurations are possible as well.
FIG. 8 depicts the annular ring 111 rotated about 90° from its position in FIG. 7 so as to reveal a second electrical connector 115 through a second aperture in the base 110 and the aperture 105b. The electrical connector 115 may be different than electrical connector 104. For instance, electrical connector 104 may be a male USB Micro A plug, whereas electrical connector 115 is a male USB Mini A plug. Other configurations are possible as well.
FIG. 9 depicts a portion of an electrical connector 104. As mentioned, the electrical connector may be a male plug configured to couple to an external device, such a cell phone or tablet computer. In some embodiments, the electrical connector 104 may be positioned in a socket of the base 110 in such a way so that the electrical connector 104 is rotatable within the socket. For instance, the electrical connector 104 may have one or more wings 114 on a housing 118 of the connector 104. The wings 114 may be received in a corresponding grooved portion of the socket of base 110 and allow for rotation of the connector 104 within the socket. Other configurations are possible as well.
FIG. 10 depicts an example block diagram depicting certain electrical components 1000 that may be included in charging device 100 and, for example, positioned within the base 110. In one embodiment, for instance, components 1000 include a male electrical connector 104, a female electrical connector 107, an array of white LEDs 112a, an array of colored LEDs 112b, a rechargeable power source 119, and power electronics 116, all coupled together by a bus 117 or other mechanism. In some embodiments, the LEDs 112a-b may be positioned within the base in such a way so as to emit light through the substantially transparent portion of a removable insert and perhaps other portions of the base 110, such as the aperture 105a, and illuminable ring 106. In addition, the corresponding male plug received by the female electrical connector 107 is a cable that may be coupled to an external power source (not shown), such as a 5V DC power source or a 120V AC power source.
Further, electrical components 1000 include power electronics 116, which are configured for receiving electricity from an external power source via electrical connector 107 and delivering electricity to the LEDs 112a-b and the male electrical connector 104 via the bus 117 or other mechanism. This arrangement enables the electrical connector 104 to provide electricity to an external device, such as a cell phone or tablet computer, and therefore power or charge a battery of the external device. In some embodiments, power electronics 116 may include a power inverter circuit 121 in order to convert alternating current (AC) electricity to direct current (DC) electricity, a voltage regulator circuit 122 in order to provide a stable DC voltage to the electrical connector 104, and/or a voltage divider circuit 123 in order to provide appropriate voltage for the LEDs.
In some embodiments, power electronics 116 may also include a toggle circuit 124 that is configured for selectively enabling one or more individual LEDs from the array of LEDs 112a-b. For instance, the circuit may operate to toggle between enabling just the white LEDs, enabling just the colored LEDs, enabling both the white and colored LEDs, and disabling both sets of LEDs. As an example, a switch may be positioned on the base 110 and coupled to the power electronics 116 via the bus 117 or other mechanism in order to selectively enable the LEDs.
In some embodiments, components 1000 may also include a rechargeable power source 119, such a lithium-ion battery or a capacitor circuit that enables the power electronics 116 to supply power to the LEDs 112 and/or an external device coupled to the electrical connector 104 when electrical connector 107 is not coupled to an external power source. In some embodiments, when electrical connector 107 is coupled to an external power source, power electronics 116 may operate to charge the rechargeable power source 119 by providing current to the rechargeable power source 119. And in some embodiments, when electrical connector 107 is not coupled to an external power source, the LEDs and/or an external device coupled to electrical connector 104 (and/or electrical connector 115) may operate to draw current from the rechargeable power source 119. It will be appreciated that other arrangements of electrical components are possible in other embodiments.
