BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an antenna device, and more particularly to an antenna device having a rotatable structure for allowing the antenna device to be freely rotated relative to the support object or device to any angular direction.

2. Description of the Prior Art

Typical antenna devices comprise an antenna housing or member solidly attached or secured onto a telecommunicating facility or the other support objects or devices, and some of the antenna housings or members may include a telescopic structure for selectively extending out of the telecommunicating facility or the other support objects or devices.

For example, U.S. Pat. No. 6,341,217 to Wong discloses one of the typical portable telephones including a shielded transmission antenna that is solidly secured to the typical portable telephone, and may not be extended relative to the typical portable telephone, such that the typical portable telephones may not easily receive telecommunicating signals.

U.S. Pat. No. 6,518,928 to Sheu discloses another typical electric facility including an antenna device rotatably secured to the typical electric facility, for being rotated relative to the typical electric facility to various angular directions. However, the antenna device of the typical electric facility may only be rotated relative to the typical electric facility in two directions only, and may not be freely rotated relative to the typical electric facility to any suitable or selected directions.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional antenna devices for telecommunicating facilities.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially toFIGS. 1 and 2, an antenna device10in accordance with the present invention is provided or arranged for pivotally or rotatably attached to a telecommunicating facility or electric facility or other support objects or devices80, and comprises a coupler11including one end12for pivotally or rotatably plugging or attaching to the telecommunicating facility or support device80, and including an orifice13formed in the other end14thereof, and preferably further including one or more slots15formed in the other end14thereof to form one or more spring arms16.

A connector20includes a chamber21formed therein, such as formed in one end thereof, for rotatably receiving or attaching the other end14of the coupler11, and may be pivotally or rotatably coupled to the coupler11with a pivot axle18(FIG. 1), to allow the connector20to be rotated relative to the coupler11about the pivot axle18. The connector20includes an aperture22formed therein and communicating with the chamber21thereof, for selectively or optionally receiving such as a protective barrel23therein (FIG. 5), and/or for receiving electric cables or wires (not shown) therein, and includes an extension24extended therefrom, such as extended from the other end thereof, opposite to the chamber21or the one end thereof. The protective barrel23may be used to reinforce the extension24of the connector20.

As best shown inFIG. 3, the connector20includes one or more peripheral ribs25extended radially and outwardly from the extension24thereof, and formed or defined between one or more peripheral grooves26, and includes a stop27extended radially and outwardly from one of the peripheral ribs25thereof, and further includes one or more projections28extended into or within one of the peripheral grooves26thereof. It is further preferable that the extension24of the connector20includes one or more slits29formed therein for increasing the resilience of the extension24of the connector20.

An antenna housing or member30includes one end31having a bore32formed therein for rotatably receiving the extension24of the connector20, and includes one or more peripheral swellings33extended radially and inwardly into the bore32thereof, and formed or defined between one or more peripheral channels34, for slidably or rotatably engaging with the corresponding peripheral grooves26and the peripheral ribs25of the connector20respectively, and thus for rotatably coupling the one end31of the antenna member30to the extension24of the connector20.

The antenna member30further includes a stop35extended into or within one of the peripheral channels34thereof, for engaging with the corresponding stop27of the connector20, and thus for limiting the antenna member30to rotate relative to the connector20, and for preventing the antenna member30from being over rotated relative to the connector20, to prevent the electric cables or wires that are coupled between the antenna member30and the connector20from being twisted.

The antenna member30further includes one or more cavities36formed in one of the peripheral swellings33thereof, and formed or defined by one or more anchor members37, for selectively receiving the projections28of the connector20, and thus for stably anchoring or positioning the antenna member30to the connector20at selected or predetermined angular positions.

The antenna member30may further include a protective sleeve or covering38(FIG. 5) engaged onto the one end31thereof, for shielding or protecting the one end31of the antenna member30and the extension24of the connector20, the protective sleeve or covering38may further be used to reinforce or to strengthen the one end31of the antenna member30and/or the extension24of the connector20.

The antenna member30may thus be rotated relative to the connector20at selected or predetermined angular positions, the connector20may be rotated relative to the coupler11, and the coupler11may be freely rotated relative to the telecommunicating facility or support device80to any suitable angular positions, such that the antenna member30may be freely rotated relative to the telecommunicating facility or support device80to any suitable angular positions.

Accordingly, the antenna device in accordance with the present invention includes a rotatable structure for allowing the antenna device to be freely rotated relative to the support object or device to any angular direction.
