ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an orientation-adjusting device, and more particular to an orientation-adjusting device for properly adjusting the orientation of a wireless transceiver so as to allow the transceiver to be fitted into a confined space.
BACKGROUND OF THE INVENTION
Universal Serial Bus (USB) has been becoming a major type of connecting ports for personal computers. As result, many newly developed peripheral equipment, e.g. Bluetooth-related peripheral equipment, are designed with USB as a standard interface. On the other hand, a wireless transceiver is more and more popular to become a part of a personal computer. Therefore, the equipment of a personal computer with a wireless transceiver interfaced therebetween with a USB adapter becomes a trend. In order to be fitted into a confined space, especially in a portable computer of small size, and perform the wireless communication function well, the wireless transceiver should be properly oriented.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide an orientation-adjusting device for properly orienting a wireless transceiver in a confined space, which preferably performs two dimensional adjustment.
A first aspect of the present invention relates to an orientation-adjusting device for adjusting an orientation of a wireless communication device. The wireless communication device is mounted in a main frame via an interface device, and the orientation-adjusting device includes a first housing for accommodating therein the wireless communication device; a second housing pivotally connected to the first housing to allow the first housing to rotate in a first direction relative thereto; and a third housing for accommodating therein the interface device, pivotally connected to the second housing to allow the second housing to rotate in a second direction relative thereto.
Preferably, the second housing includes a passage for penetrating therethrough a signal cable connecting the wireless communication device and the interface device.
In an embodiment, the first housing includes a first cylindrical portion for sleeving therearound the second housing, and serving as a first shaft for rotating the first housing therewith in the first direction.
In an embodiment, the second housing includes a first engaging part, the third housing includes a second engaging part, and the first and second engaging parts pivotally connected to each other to serve as a second shaft for rotating the second housing therewith in the second direction, and form a second hollow cylindrical portion for penetrating therethrough the signal cable.
In an embodiment, the second housing includes a hollow disk body secured to the first engaging part for sleeving around the first cylindrical portion. Preferably, the second hollow cylindrical portion serves as a rotation-angle confiner of the first housing in the first direction.
Preferably, the first direction is perpendicular to the second direction so as to perform two-dimensional adjustment.
For example, the wireless communication device can be a wireless transceiver, the main frame can be a personal computer, and the interface device can be a Universal Serial Bus (USB) adapter.
A second aspect of the present invention relates to another orientation-adjusting device for adjusting an orientation of a wireless communication device. The orientation-adjusting device includes a first housing for accommodating therein the wireless communication device, which includes a first shaft; a second housing including a first portion penetrating therethrough the signal cable and sleeving around the first shaft, and a second portion being of a hollow cylindrical shape; and a third housing including a third portion for accommodating therein the interface device, and a fourth portion being of a hollow cylindrical shape, engaging with the second portion of the second housing to form a hollow cylinder for penetrating therethrough the signal cable, and serving as a second shaft, wherein the first and second housings optionally perform a first relative rotating motion with the first shaft, and the second and third housings optionally perform a second relative rotating motion with the second shaft to adjust the orientation of the wireless communication device.
In an embodiment, the first portion of the second housing being of a disk shape.
Preferably, the first and second relative rotating motions are in different directions so as to perform two-dimensional adjustment.
A third aspect of the present invention relates to an orientation-adjustable transceiver assembly, which includes a transceiver mounted in a first housing; a signal cable connected to the transceiver and penetrating through a second housing which pivots relative to the first housing to adjust the orientation of the transceiver in a first direction; and an interface device connected to the signal cable and mounted in a third housing which pivots relative to the second housing to adjust the orientation of the transceiver in a second direction different from the first direction.
In an embodiment, the first housing includes a first shaft for sleeving therearound the second housing, and allowing the second housing to pivot thereabout in the first direction.
In an embodiment, the second housing includes a first engaging part, the third housing includes a second engaging part, and the first and second engaging parts engage with each other to form a second shaft for allowing the third housing to pivot thereabout in the second direction.
Preferably, the second shaft is hollow for penetrating therethrough the signal cable.
Preferably, the interface device is a Universal Serial Bus (USB) adapter.
