Electrical device for a portable electronic device
View Patent ↗A charger unit includes: a housing, prongs for engaging an electrical outlet, the prongs being coupled to one another by a cross-member and being movable relative to the housing between a retracted position in which the prongs are received in the housing and an extended position in which the prongs protrude from the housing, the prongs being biased toward the extended position, a locking arm comprising a first end, a cut out for receiving the cross-member when the prongs are in the retracted position and a second end for abutting the cross-member when the prongs are in the extended position, the first end of the locking arm being coupled to a carriage and the cutout being provided between the first end and the second end, the locking arm being movable by the carriage into and out of engagement with the cross-member and the locking arm being biased toward the passage.
1. An electrical device comprising:
a housing;
prongs for engaging an electrical outlet, the prongs being coupled to one another by a cross-member and being movable relative to the housing between a retracted position in which the prongs are received in the housing and an extended position in which the prongs protrude from the housing, the prongs being biased toward the extended position;
a locking arm comprising a first end, a cutout for receiving the cross-member when the prongs are in the retracted position and a second end for abutting the cross-member when the prongs are in the extended position, the first end of the locking arm being coupled to a carriage and the cutout being provided between the first end and the second end, the locking arm being movable by the carriage into and out of engagement with the cross-member and the locking arm being biased toward the prongs; and
electrical components for electrically communicating with a portable electronic device.
2. An electrical device as claimed in claim 1 , wherein the prongs are movable through a passage and the locking arm is movable into and out of the passage, the passage being defined by guides.
3. An electrical device as claimed in claim 1 , wherein an end of the carriage is accessible from outside of the housing to move the carriage out of the passage to allow for the prongs to move between the retracted position and the extended position.
4. An electrical device as claimed in claim 1 , wherein the housing comprises a cover that is coupled to a base unit.
5. An electrical device as claimed in claim 4 , wherein the cover comprises slots for receiving the prongs when the prongs are in the extended position.
6. An electrical device as claimed in claim 2 , wherein the guides are coupled to a base unit of the housing.
7. An electrical device as claimed in claim 6 , wherein the cross-member comprises an aperture for receiving a post, the post extending through the passage.
8. An electrical device as claimed in claim 7 , wherein the carriage comprises a post-receiving slot for receiving the post, the carriage being provided between the base unit and the cross-member and the post-receiving slot being sized to allow for movement of the carriage relative to the base unit.
9. An electrical device as claimed in claim 1 , wherein the second end of the locking member abuts an underside of the cross-member when the prongs are in the extended position.
10. An electrical device as claimed in claim 3 , wherein an end surface of the end comprises a feature for facilitating user-location thereof, the feature comprising one of: a color, a texture, a word, a logo, a symbol and characters.
11. An electrical device as claimed in claim 10 , wherein the word is the word “push”.
12. An electrical device as claimed in claim 1 , comprising a pair of locking arms.
