Abstract
This invention relates to a rotatable device having two arms rotatably connected about a hollow hub wherein the arms include a cable extending through a passageway and the hub so as to minimize bending of the cables about each other when the arms are in a compact position. In particular this invention relates to a foldable GPS compass and a method relating thereto to present a compact folded device that is easier to install with minimal bending of the cables. The invention also discloses a detent disposed within the hub for accurate selective placement of the arms and method relating thereto.
Claims15
A rotatable GPS compass comprising:
- (a) a housing comprising a first arm and a second arm, the first arm of a first fixed length and the second arm of a second fixed length, each of said first and second arms rotatably connected at one end thereof to a hub, and rotatable between:
- (i) a compact position where said first and second arms overlie each other to
- (ii) an extended position where said first and second arms are disposed along a first direction;
- (b) the first arm carrying a first antenna at another end of the first arm;
- (c) the second arm carrying a second antenna at another end of the second arm;
- (d) the first and second arms including a passageway communicating with the hub;
- (e) one cable extending from the first antenna through the passageway of the first arm to the hub;
- (f) another cable extending from the second antenna through the passageway of the second arm to the hub;
- (g) wherein the first and second cables are coiled within said hub so as to minimize torsional movement between the compact and extended positions.

A rotatable GPS compass comprising:
- (a) a first arm of a first fixed length and a second arm of a second fixed length rotatably connected at one end thereof to a hub, and rotatable between:
- (i) a compact position where said first and second arms overlie each other;
- to
- (ii) an extended position where said first and second arms are disposed along a first direction;
- (b) the first arm carrying a first antenna at another end of the first arm;
- (c) the second arm carrying a second antenna at another end of the second arm;
- (d) the first and second arms including a passageway communicating with the hub;
- (e) one cable extending from the first antenna through the passageway of the first arm to the hub;
- (f) another cable extending from the second antenna through the passageway of the second arm to the hub;
- (g) wherein the first and second cables are coiled within said hub so as to minimize torsional movement between the compact and extended positions;
- (h) an extension for housing control means at one end thereof and to present the hub at another end thereof;
- (i) the first fixed length of said first arm is shorter than said second fixed length of said second arm so that said first and second arms are stacked upon one another in the compact position, and;
- (j) the first and second arms extend in a first linear direction in to the extended position.

A rotatable GPS compass comprising:
- (a) a first arm of a first fixed length and a second arm of a second fixed length, where said first length of said first arm is shorter than the second fixed length of said second arm, said first and second arms connected at one end thereof to a hub having an axis of rotation for rotation of said first arm relative said second arm about said axis of rotation between:
- (i) a compact position where said first and second arms overlie each other to
- (ii) an extended position with said first and second arms disposed along an extended linear direction;
- (b) the first arm carrying a first antenna at another end of the first arm;
- (c) the second arm carrying a second antenna at another end of the second arm;
- (d) whereby said first and second antennas are adjacent one another in said compact position, and where said first and second antennas are spaced apart from each other in said extended linear position;
- (e) the first and second arms including a first and second passageway, respectively communicating with the hub;
- (f) cable means extending from the first antenna through the passageway of the first arm to the hub and through the passageway of the second arm to the second antenna;
- (g) wherein the cable means is coiled solely upon itself within said hub so as to minimize torsional movement between the compact and extended positions.
