Abstract

A consumer electronics device charging device having a pair of rotatable blades, wherein the blades are rotatable from a deployed position in which ends of the blades are inserted into a standard 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.

Claims

1. A smart phone charging device, comprising:

(a) a housing;

(b) a plug unit disposed in the housing, the plug unit having;

(i) a pair of rotatable blades, wherein the blades are rotatable from a deployed position in which ends of the blades are positioned to be received within a wall outlet to a retracted position in which the ends of the blades are spread apart from one another; and

(ii) a mechanism for rotating the blades from the retracted position to the deployed position;

(c) electrical circuitry in the housing connecting the blades of the plug unit to a smart phone battery; and

(d) a slide that is moveable between a first position that exposes the blades, and a second sliding position that substantially covers the blades.

2. A charging device, comprising:

(a) a housing;

(b) a plug unit disposed in the housing, the plug unit having;

(i) a pair of rotatable blades, wherein the blades are rotatable from a deployed position in which ends of the blades are positioned to be received within a wall outlet to a retracted position in which the ends of the blades are spread apart from one another; and

(ii) a mechanism for rotating the blades from the retracted position to the deployed position; and

(c) electrical circuitry in the housing connecting the blades of the plug unit to a battery,

wherein a base of each of the rotatable blades are mounted onto a spring biased rotatable member.

3. A charging device, comprising:

(a) a housing;

(b) a plug unit disposed in the housing, the plug unit having;

(i) a pair of rotatable blades, wherein the blades are rotatable from a deployed position in which ends of the blades are positioned to be received within a wall outlet to a retracted position in which the ends of the blades are spread apart from one another; and

(ii) a mechanism for rotating the blades from the retracted position to the deployed position; and

(c) electrical circuitry in the housing connecting the blades of the plug unit to a battery,

wherein the housing is attached to a smart phone, and wherein the housing is attached to the bottom of the smart phone.

4. A charging device, comprising:

(a) a housing;

(b) a plug unit disposed in the housing, the plug unit having;

(i) a pair of rotatable blades, wherein the blades are rotatable from a deployed position in which ends of the blades are positioned to be received within a wall outlet to a retracted position in which the ends of the blades are spread apart from one another; and

(ii) a mechanism for rotating the blades from the retracted position to the deployed position;

(c) electrical circuitry in the housing connecting the blades of the plug unit to a battery; and

a spring biasing system that urges the blades into the deployed position.

5. The charging device of claim 4, further comprising:

a restraint mechanism for holding the blades in the retracted position, wherein releasing the restraint mechanism causes the blades to spring into their deployed position.

6. A charging device, comprising:

(a) a housing;

(b) a plug unit disposed in the housing, the plug unit having;

(i) a pair of rotatable blades, wherein the blades are rotatable from a deployed position in which ends of the blades are positioned to be received within a wall outlet to a retracted position in which the ends of the blades are spread apart from one another; and

(ii) a mechanism for rotating the blades from the retracted position to the deployed position;

(c) electrical circuitry in the housing connecting the blades of the plug unit to a battery; and

a latching mechanism for holding the blades in their retracted position comprising;

a biasing spring for each blade;

a roller from which each blade extends;

a slot on the side of the roller;

a moveable switch having a forward projection that is received within the slot on the side of the rollers; and

a biasing spring that advances the moveable switch such that forward projection remains positioned within the slot on the side of the rollers thereby preventing the blades from rotating from their retracted position, but wherein manually sliding the moveable switch away from the blades causes the forward projection to slip out of the slots on the side of the rollers, thereby releasing the rollers causing the biasing springs to rotate the blades to their deployed positions.

7. A charging system for a smart phone, comprising:

(a) a smart phone having;

(i) an internal battery, and

(ii) a power connector configured to receive external power and transmit the power to the internal battery;

(b) a charging device, having;

(i) a housing;

(ii) a plug unit disposed in the housing, the plug unit having;

(a) a pair of rotatable blades, wherein the blades are rotatable from a deployed position in which ends of the blades are dimensioned to be received within a wall outlet to a retracted position in which the ends of the blades are spread apart from one another; and

(b) a mechanism for rotating the blades from the retracted position to the deployed position,

(iii) electrical circuitry in the housing connected to the blades of the plug unit, wherein the charging device further comprises a battery disposed in the housing.
