Patent ID: 8446336

Claim:
A multi-directional pivoting antenna, comprising: an antenna case having an antenna unit received therein; the antenna case being provided at a proximal end with a rearward opened recess to provide a pivoting space thereat, and a wall portion of the antenna case corresponding to the pivoting space being upward extended to provide a holding plate, which has a free end formed into a first engaging part, such that the holding plate and the antenna case cooperatively define a holding space therebetween; and the antenna case being provided on at least a wall portion corresponding to at least one of two lateral sides of the pivoting space with a receiving slot; a pivotal device being correspondingly pivotally connected to the proximal end of the antenna case, and including a pivot block, a seat, and a pivot post; the pivot block having a top portion pivotally turnably received in the holding space defined between the antenna case and the holding plate for the holding plate to bear thereon; the top portion of the pivot block being provided with a plurality of circumferentially spaced second engaging parts, which are externally configured corresponding to the first engaging part; the pivot block being provided on at least one of two lateral ends with an outward extended pivot shaft, which is correspondingly pivotally fitted in the at least one receiving slots on the antenna case; the seat being located below the pivot block and the pivot post being downward extended from one side of the seat opposite to the pivot block; and the pivot post being formed on an outer wall surface near the seat with an outward protruded stopper, and on the outer wall surface at a predetermined position with a first friction section; and a pivot base being correspondingly fitted around the pivot post of the pivotal device to upward press against the seat; the pivot base being provided with an axial opening, such that the pivot post is tightly but pivotally turnably fitted in the axial opening; a second friction section being provided on a wall surface of the pivot base surrounding the axial opening for engaging with the first friction section on the pivot post; the pivot base being further provided on one side facing toward the seat with a limiting recess, in and along which the stopper moves when the pivot post is pivotally turned in the axial opening; and the limiting recess including a raised limiting portion for stopping the stopper from moving any further when the pivot post is pivotally turned clockwise or counterclockwise, so as to define a maximum range of angles within which the pivot device can be pivotally turned relative to the pivot base.
