Abstract

A swivel-type portable flash device includes a C-shaped swivel cover that rotates (swivels) relative to a housing between an open position in which a plug connector is exposed for insertion in a host system, and a closed position in which the plug connector is covered and protected by the swivel cover. The swivel cover is permanently rotatably connected to the housing by ring-shaped protrusions that are movably engaged inside corresponding recessed ring-shaped grooves formed in upper/lower walls of the housing, whereby the swivel cover is manually rotatable relative to the housing between the opened and closed positions. The swivel cover includes locking structures (e.g., locking notches) disposed on the ring-shaped protrusions, and the housing includes second locking structures disposed in the recessed ring-shaped grooves, where the first and second locking structures prevent rotation of the swivel cover when the plug connector is closed.

Claims

1. A portable flash device comprising:

an elongated housing including an upper housing wall defining a first recessed ring-shaped groove, a lower housing wall defining a second recessed ring-shaped groove, and a peripheral wall that extends between outer edges of the upper and lower housing wall such that an enclosed chamber is defined between the upper housing wall, lower housing wall and peripheral wall;

at least one electronic device disposed in the enclosed chamber of the housing;

a plug connector fixedly connected to the housing and extending from a front wall portion of the peripheral wall, the plug connector being electronically connected to said at least one electronic device; and

a C-shaped swivel cover including an upper cover wall and a lower cover wall that are integrally connected by an end wall,

wherein the swivel cover is permanently rotatably connected to the housing by way of a first ring-shaped protrusion that extends perpendicular to the upper cover wall and is movably engaged in the first recessed ring-shaped groove, and by way of a second ring-shaped protrusion that extends perpendicular to the lower cover wall and is movably engaged in the second recessed ring-shaped groove, whereby the swivel cover is manually rotatable relative to the housing between a first position in which portions of the upper cover wall and the lower cover wall and the end wall substantially enclose the plug connector, and a second position in which the plug connector is operably exposed for insertion in a host system,

wherein the end wall is spaced from a front edge of the plug connector by a first minimal offset distance that provides a clearance for rotation of the swivel cover,

wherein the peripheral wall of the housing further includes a rear wall portion that is disposed opposite to the front wall portion, and

wherein the first recessed ring-shaped groove and the second recessed ring-shaped groove are respectively located approximately midway between the rear wall portion and a front edge of the plug connector, whereby when the swivel cover is manually rotated 180°

from the first position, the end wall is spaced from the rear wall portion by a second minimum offset distance that provides a clearance for rotation of the swivel cover and is substantially equal to the first minimal offset distance.

2. The flash device according to claim 1,

wherein the end wall comprises a substantially semi-cylindrical structure extending between the upper cover wall and the lower cover wall.

3. The flash device according to claim 1,

wherein the swivel cover further comprises at least one integrally connected first locking structure disposed on at least one of the first ring-shaped protrusion and the second ring-shaped protrusion, and

wherein the housing further comprises at least one integrally molded second locking structure disposed in at least one of the first ring-shaped groove and the second ring-shaped groove, and

wherein the swivel cover is mounted on the housing such that the first locking structure operably engages the second locking structure when the plug connector is in the first position such that a greater manual force is required to rotate the swivel cover out of the first position than to rotate the swivel cover between the first position and the second position.

4. The flash device according to claim 1,

wherein the swivel cover is mounted on the housing such that the first ring-shaped protrusion is biased into the first ring-shaped groove and the second ring-shaped protrusion is biased into the second ring-shaped groove,

wherein the swivel cover further comprises at least one integrally connected snap slot disposed on at least one of the first ring-shaped protrusion and the second ring-shaped protrusion, and

wherein the housing further comprises at least one integrally molded snap tab disposed in at least one of the first ring-shaped groove and the second ring-shaped groove, and

wherein the swivel cover is mounted on the housing such that the snap slot operably engages the snap tab when the plug connector is in the first position.

5. The flash device according to claim 1, wherein the swivel cover is attached to housing such that a maximum overall thickness of the flash device is equal to a perpendicular distance between the outermost surfaces of the upper cover wall and the lower cover wall.

6. The flash device according to claim 5,

wherein the upper cover wall defines a first circular hole surrounded by the first ring-shaped protuberance and the lower cover wall defines a second circular hole surrounded by the second ring-shaped protuberance, and

wherein the flash device further comprises:

a first rivet cap having a cap portion disposed inside the first circular hole and a base structure fixedly attached to the upper housing wall; and

a second rivet cap having a cap portion disposed inside the second circular hole and a base structure fixedly attached to the lower housing wall.

7. The flash device according to claim 6,

wherein the upper housing wall defines a first circular rivet opening surrounded by said first recessed ring-shaped groove, and the lower housing wall defines a second circular rivet opening surrounded by said second recessed ring-shaped groove,

wherein the first rivet cap comprises a plurality of first snap arms extending through the first circular rivet opening and being snap-coupled to the upper housing wall, and

wherein the second rivet cap comprises a plurality of second snap arms extending through the second circular rivet opening and being snap-coupled to the lower housing wall.

8. The flash device according to claim 6, further comprising a light source disposed inside the housing and positioned adjacent to at least one of the first and second rivet openings, and

wherein at least one of the first and second the rivet caps comprise a light permissive material.

9. The flash device according to claim 5,

wherein the upper cover wall defines a first circular hole surrounded by the first ring-shaped protuberance and the lower cover wall defines a second circular hole surrounded by the second ring-shaped protuberance, and

wherein the housing further comprises:

a first circular connection structure integrally molded on the upper housing wall extending into the first circular hole and terminating at a first disk-shaped surface, and

a second circular connection structure integrally molded on the lower housing wall and extending into the second circular hole and terminating at a second disk-shaped surface,

wherein a maximum thickness of said housing defined between said first and second disk-shaped surfaces of the first and second circular connection structures is equal to a thickness a thickness between the outermost surfaces of upper cover wall and lower cover wall.

10. The flash device according to claim 9, further comprising:

a light source disposed inside the housing and positioned between the plug connector and the first circular connection structure; and

a light pipe disposed in the upper housing wall adjacent to the light source.

11. The flash device according to claim 1, wherein the housing comprises an upper housing portion and a lower housing portion, that are connected together along a seam defined in the peripheral wall.

12. The flash device according to claim 1, wherein the housing comprises a tubular housing portion and at least one of a front cap portion fixedly attached to a front edge of the tubular housing portion and a rear cap portion fixedly attached to a rear edge of the tubular housing portion.
