BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a swinging display mounting structure and more particularly, to such a swinging display mounting structure, which enables the display to be turned about an axis in a receiving open chamber in the front side of a housing and set between an exposed position and a hidden position.
2. Description of the Related Art
Since the invention of CRT (Cathode Ray Tube) in 1897, CRT has been intensively used in televisions and computer monitors for image output. However, following fast development of high technology, a variety of display devices including TFT LCD (Thin Film Transistor Liquid Crystal Display), PDP (Plasma Display Panel) and FPD (Flat Panel Display) have been developed for use to substitute for conventional CRT displays. Nowadays, motor computer systems use a TFT LCD instead of a conventional CRT monitor. PDP was commercialized in 1985. In Nagano Winter Olympics Japan, many Japanese manufacturers put different big size PDPs into the market. Following the step of TFT LCD, FED (Field Emission Display) has also been well developed to challenge the market.
For the advantages of fine picture quality, low radiation, zero magnetic wave, small size, and low power consumption, LCD has been intensively used in motor vehicles (cars, buses, and etc.). However, after installation of a LCD in a motor vehicle, for example, in the instrument panel or the headrest of a chair, the user cannot set the LCD in a received position to prevent damage of an external body to the display screen accidentally when the LCD is not in use. Further, because different users have different body sizes and a different sitting posture causes a change of the view angle, it may be necessary to adjust the angular position of a LCD in a motor vehicle to fit different users (passengers). However, conventional LCD mounting designs do not allow the user to adjust the angular position of the LCD. A LCD mounting design, which uses a bracket installed in the headrest of a vehicle's chair to support a LCD, enabling the user to adjust the angular position of the LCD. However, this design still has drawbacks. One drawback of this design is its limited adjustment range. Another drawback of this design is its big installation space requirement.
Further, because a LCD is a small but expensive device. When a car parked on a roadside or in a parking lot, the display in the car can easily be recognized from the outside of the car by a person passing by, thereby luring a thief to steal the LCD.
Therefore, it is desirable to provide a display mounting structure that eliminates the aforesaid problems.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a swinging display mounting structure, which allows the user to adjust the view angle of the display. It is another object of the present invention to provide a swinging display mounting structure, which allows the user to set the display between the operative position to have the display screen exposed to the outside, and the non-operative position to have the display screen kept from sight. To achieve these and other objects of the present invention, the swinging display mounting structure comprises a housing, which has a receiving open chamber, a display, and a joint coupled between the housing and the display to support the display in the receiving open chamber for enabling the display to be turned about an axis passing through the joint and set in one of a series of angular positions.

DETAILED DESCRIPTION OF EMBODIMENT
Referring to FIG. 1, a swinging display mounting structure in accordance with a first embodiment of the present invention is shown comprising a housing 1, a display 2, and a joint 3. The housing 1 has a front receiving open chamber 11, and a set of buttons 12 at the front side. The display 2 is a liquid crystal display receivable to the front receiving open chamber 11. The joint 3 is adapted to support the display 2 in the front receiving open chamber 11 and to hold the display 2 between two reversed positions. According to this embodiment, the joint 3 comprises two barrels 32 symmetrically provided at two opposite sides inside the front receiving open chamber 11, and two pivot pins 31 respectively provided at two opposite lateral sides of the display 2 and respectively pivoted to the barrels 32 for enabling the display 2 to be turned about the imaginary axis passing through the barrels 32 and the pivot pins 31. The barrels 32 each have a stop portion 321 projecting from the inside wall thereof. The pivot pins 31 each have a protruded locating portion 311 for stopping against one side of the stop portion 321 of the respective barrel 32. Further, electric wires (not shown) are extended out of the display through the pivot pins 31 (the pivot pins 31 are tubular pins) and the barrels 32 and electrically connected to the buttons 12 so that the user can operate the buttons 12 to control the operation of the display 2.
Referring to FIGS. 2˜4 and FIG. 1 again, the user can turn the display 2 about the imaginary axis passing through the barrels 32 and the pivot pins 31 between two positions, namely, the first position where the protruded locating portion 311 of each pivot pin 31 is respectively stopped at one side of the stop portion 321 of the respective barrel 32 and the display 2 has the display screen thereof exposed to the outside (see FIG. 3), and the second position where the protruded locating portion 311 of each pivot pin 31 is respectively stopped at the other side of the stop portion 321 of the respective barrel 32 and the display 2 has the display screen thereof received inside the housing 1 and kept from sight (see FIG. 4). Alternatively, the joint 3 can be so made that the display 2 can be selectively set in one of a series of angular positions.
FIG. 5 shows an application example of the present invention. According to this application example, the housing 1 can be installed in the headrest of the driver or passenger's seat 41 inside a car.
FIG. 6 shows another application example of the present invention. According to this application example, the housing 1 is installed in the instrument board 42 inside a car.
