DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-5, a multidirection rotatable electronic device in accordance with the present invention is shown comprised of a connecting unit 10 and a body unit 20.

The connecting unit 10 comprises a connecting member 11 and an adapter 12.

The connecting member 11 has a front connecting portion 13 made in the form of, for example, a USB (universal serial bus) plug, and a rear mounting portion 14 at the back side of the front connecting portion 13. The adapter 12 is comprised of a coupling member 16 and a limiter 17. The coupling member 16 is formed of two symmetrical half shells 161 and 162, having a hollow base 163, a pivoting portion 164 backwardly extending from the back side of the base 163, an accommodating chamber 165 defined in the hollow base 163, and a front opening 166 at the front side of the hollow base 163 in communication with the accommodating chamber 165. The pivoting portion 164 is a semispherical ball socket in this preferred embodiment. The rear mounting portion 14 of the connecting member 11 is received in the accommodating chamber 165 of the coupling member 16. The front connecting portion 13 of the connecting member 11 extends out of the hollow base 163 of the coupling member 16 through the front opening 166. The limier 17 is a hollow, semispherical member having a rib 171 protruded from the periphery of the semispherical body thereof, a neck 173 perpendicularly extending from the flat bottom wall thereof, and longitudinal crevices 172 cut through the tubular neck 173 at two sides. The tubular neck 173 is coupled to the pivoting portion 164 of the coupling member 16, allowing free rotation of the limiter 17 relative to the coupling member 16.

The body unit 20 comprises a housing 21 and an electronic circuit assembly 22. The housing 21 has a coupling structure 23. The coupling structure 23 comprises a locating groove 231 formed in the front side of the housing 21 for receiving the ribs 171 of the limiter 17, and two bearing blocks 232 bilaterally fixedly provided inside the housing 21 for supporting the pivoting portion 164 of the coupling member 16 and the limiter 17 in the coupling member 16. The bearing blocks 232 each have an arched slot 233. The electronic circuit assembly 22 is a transmitter receiver circuit board mounted inside the housing 21 for transmitting and receiving specific wireless signal.

The use and advantages of the present invention will be filly understood

from the following description.

At first, the two half shells 161 and 162 are attached to the connecting member 11 and fastened together to have rear mounting portion 14 of the connecting member 11 be received in the accommodating chamber 165 of the coupling member 16 and the front connecting portion 13 extend out of the coupling member 16 through the front opening 166, and then the tubular neck 173 of the limiter 17 is inserted into the pivoting portion 164 of the coupling member 16 with force for allowing free rotation of the limiter 17 relative to the coupling member 16, and then the pivoting portion 164 with the limiter 17 are set in the coupling structure 23 of the housing 21 and supported between the bearing blocks 232 to have the rib 171 of the limiter 17 be engaged in the locating groove 231 of the coupling structure 23 to limit turning of the limiter 17 relative to the housing 21 to a vertical direction (see FIG 6). When assembled, the crevices 172 of the limiter 17 are constantly kept in communication with the arched slots 233 of the bearing block 232 for the passing of an electric wire that connects the electric contacts (not shown) in the connecting member 11 to the electronic circuit assembly 22. This electric wire (not shown) has one end electrically connected to the electronic circuit assembly 22, and the other end inserted in proper order through the arched slots 233 of the bearing blocks 232 and the crevices 172 of the limiter 17 into the pivoting portion 164 and then extended through the hollow base 163 of the coupling member 16 into the front connecting portion 13 of the connecting member 11 and electrically connected to the electric contacts in the connecting portion 13 of the connecting member 11. Further, as shown in FIG. 7, the coupling member 16 can be rotated over 3600 relative to the limiter 17, i.e., the connecting unit 10 can be rotated over 360 relative to the housing 21.

FIG 8 shows an alternate form of the present invention. According to this second embodiment, stop rods 169 and 175 are respectively provided inside the pivoting portion 164 and at the limiter 17 to limit the angle of rotation of the pivoting portion 164 (i.e., the coupling member 16) relative to the limiter 17, preventing overtwist of the electric wire, i. e., the connecting unit 10 can be rotated within 360 relative to the housing 21. Further, in order to reinforce the connection strength between the pivoting portion 164 and the limiter 17, the pivoting portion 164 is made having an inside annular flange 167 coupled to an outside annular groove 174 around the periphery of the tubular neck 173 of the limiter 17.

When connected the front connecting portion 13 of the connecting unit 10 to a corresponding port of a computer, signal from the computer is transmitted through the front connecting portion 13 to the electronic circuit assembly 22, and then modulated by the electronic circuit assembly 22 and transmitted to the outside wirelessly. When received an external wireless signal, the electronic circuit assembly 22 demodulates the signal and then transmits the demodulated signal to the front connecting portion 13 and then to the computer. The location or angle of the electronic circuit assembly 22 may have to be changed to fit the transmission or receiving of a wireless signal. In this case, the user can conveniently adjust the position of the body unit 20 relative to the computer to the desired angle.

The invention can be used in a wireless network receiver or wireless mouse receiver, as well as any of a variety of other electronic devices. For example, the electronic circuit assembly 22 can be a data storage circuit assembly to form a mobile memory stick; the electronic circuit assembly 22 can be an electric connector to form an electric adapter; the electronic circuit assembly 22 can be a socket terminal circuit assembly to form an electric outlet; the electronic circuit assembly 22 can be an electric plug terminal circuit assembly to form an electric plug.

The embodiments described above are given by way of examples only, and modifications will be apparent to persons skilled in the art without departing from the scope of the invention as defined by the appended claims.
