2. Description of the Prior Art
With increasing developments of technology and economics, people have growing demands for leisure, recreation and information. As a result, telematics products such as video and audio devices for use in cars and mobile information equipment have been developed and introduced. Among them Liquid crystal display (LCD) device is an indispensable facility. For the car use LCD devices now on the market, folding and storing operations generally can be categorized into three types, i.e. fully automatic, semi-automatic and manual. The fully automatic type employs electric and precise electronic elements to do control function. The display panel of the display device may be unfolded and turned and anchored on a desired position by one push. However it is very expensive.
The semi-automatic and manual types have to be turned and adjusted by people manually to set the display panel at a desired position. While they are less expensive, they are not convenient for use. Hence the conventional display devices all have their share of problems, either expensive or inconvenient to use.
Moreover, in order to facilitate folding and storing, the folding display panel of the LCD device usually is located on a lower side of the case.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1, 2, 3, 4 and 16, the mechanical LCD device according to the invention mainly includes an extendable deck 2 in a case 1. The case also has a coupling mechanism 3 on one side. The front side of the extendable deck 2 is pivotally coupled with a display panel holding mechanism 4. The display panel holding mechanism 4 has a downward folding adjustment means 5 linking to the front side of the extendable deck 2.
The case 1 is hollow and has a face panel 11 at the front end with a window 111 formed thereon to allow the display panel holding mechanism 4 and related s elements to be extended outwards. On an inner side of the window 111, there is a sloped trough 112 on a lateral side. The case 1 has a first channeling mechanism 12 and a second channeling mechanism 13 located respectively on two sides corresponding to each other to guide the extendable deck 2 to retract inwards or extend outwards at desired locations. The first channeling mechanism 12 has a first elevation sustaining plate 121 and a sliding rod 123 coupling on a sliding block 122. The second channeling mechanism 13 has a second elevation sustaining plate 131 and a gear rack 132.
The extendable deck 2 is located above the elevation sustaining plates 121 and 131 and may be extended through the window 111 outside the case 1. The extendable deck 2 has a rear section with one side fastening to the sliding block 122 of the first channeling mechanism 12 and another side has a damper 21 engaging with the gear rack 132 of the second channeling mechanism 13. The rear end of the extendable deck 2 also has respectively a push lug 22 and 23 on two sides to ram against an elastic reed A located at the front end of the elevation sustaining plates 121 and 131. The push lug 23 has a binary switch B 1 on an inner side corresponding to a latch tongue B2 located on the rear side of the case 1. The front end of the extendable deck 2 has respectively a first and a second pivot seat 24 and 25 fastened to two sides thereof. The first and the second pivot seats 24 and 25 are bridged by a connection deck 26.
The coupling mechanism 3 (referring to FIG. 3) is located on one side of the extendable deck 2 to control folding, latching and releasing of the display panel holding mechanism 4. It includes: a partition 31 located above the extendable deck 2 having a torsional spring housing zone 311 and a notch 312 on one side, and two axle holding docks 313 and 314 extended from two ends adjacent to the notch 312; a hollow first hub 32 for housing an axle C having a hook 321 on one side that has a slant surface and a projection 322 on another side. The projection 322 has a trough 3221 on a rear side; a hollow second hub 33 for housing the axle C having a lug 331 on one side corresponding to the trough 3221 and a L- shaped strut 332 extended outwards from another side, and a slant bucking member 334 on another side opposite to the L-shaped strut 332 corresponding to the sloped trough 112 of the face panel 11; and a torsional spring 34 having one end engaging with the L-shaped strut 332 and other end pressing the torsional spring housing zone 311 of the partition 31.
The torsional spring 34 pushes the first and the second hubs 32 and 33 to one side of the partition 31 in normal conditions.
The display panel holding mechanism 4 has a panel 41 for holding a LCD panel 40. The panel 41 has a lower edge forming a trough 42 corresponding to the hook 321 of the coupling mechanism 3. The trough 42 has a notch 421. In the middle portion of the back side of the panel 41, there are a first and a second pivot docks 45 and 43 on two sides corresponding to the first and second pivot seat 24 and 25 of the extendable deck 2, and are pivotally coupled respectively with stub shafts C1 and C2. The back side of the display panel holding mechanism 4 further has a downward folding adjustment means housing zone 44 which has respectively a sliding block housing trough 441 and 442 on two sides. In the center there are a bordering strut 447, a spring housing trough 443 S and a housing trough 444. The housing trough 444 has a plurality of apertures 445 and is covered by a cover plate 446.
The downward folding adjustment means S is located in the display panel holding mechanism 4 and is connected to the extendable deck 2. It includes a downward folding actuation assembly SA and an angle adjustment assembly 5B.
The downward folding actuation assembly SA is to actuate downward folding of the display panel holding mechanism 4. It includes: two dampers S1 and 52 located respectively on the outer side of the sliding block housing trough 441 and 442; IS a sliding board 53 which has gear racks 531' and 531" on two sides corresponding to the dampers S1 and 52, latch troughs 532' and 532" on two sides of the bottom, a longitudinal trough 534 in the center, and struts 533' and 533" on two sides of an upper section to anchor one end of springs D1 and D2.
The springs D1 and D2 have other end fastening to the strut 448 on the back side of the display panel holding mechanism 4; and an elevation angle push plate 58 which has respectively a stub shaft 581 extended outwards from two sides of the upper end and the lower end to couple with the connection deck 26 of the extendable deck 2 and the latch troughs 532' and 532" of the sliding board 53.
The angle adjustment assembly 5B is to adjust and remember the turning elevation angle of the display panel holding mechanism 4.It includes: an anchor member 55 which has a strut 551 on the bottom of the front side to compress a spring E located in the spring housing trough 443, and an anchor gear rack 552 and two elongated notches 553 on the back side, and a slant bucking member 554 on the lower edge; and an anchor push button 56 located on the front side of the display panel holding mechanism 4 that has a plurality of latch struts 561 to run through apertures 445 of the display panel holding mechanism 4 to fasten to an anchor plate 57 on the back side of the display panel holding mechanism 4, and is pressed by a spring F in normal conditions. The anchor plate 57 has a gear rack 571 corresponding to the anchor gear rack 552 of the anchor member 55.
By means of the construction set forth above (referring to FIGS. 5 through 12), when an user wants to retract and store the LCD panel 40, he/she only has to push the panel 41 of the display panel holding mechanism 4 rearwards, the LCD panel 40 may be turned to a horizontal position, and the stub shafts C 1 and C2 of the first and second hubs 32 and 33 serve as the axes of the display panel holding mechanism 4, the elevation angle push plate 58 of the downward folding actuation assembly 5A is driven and turned rearwards because the trough 42 of the panel 41 rams the slant surface of the hook 321 of the first hub 32 when the panel 41 is turned horizontally. After the trough 42 has passed over the slant surface of the hook 321, the returning elastic force of the torsional spring 34 moves the hook 321 into the trough 42 (meanwhile the L-shaped strut 332 is upright, will be discussed later). Therefore the display panel holding S mechanism 4 is prevented from returning. User can continuously push the display panel holding mechanism 4 into the case 1, and the push lugs 22 and 23 push the elastic reeds A on two sides of the case 1 to extend. When the extendable deck 2 is moved to the rear side of the case 1, the binary switch B 1 is latched on the latch tongue B2 to prevent the extendable deck 2 from being extended outwards. Thus the display panel holding mechanism 4 may be housed and stored. When the user wants to unload the display panel holding mechanism 4 for viewing, push the display panel holding mechanism 4 again, the binary switch B 1 is released from the latch tongue B2, the winding elastic force of the elastic reed A pushes the push lugs 22 and 23, and the extendable deck 2 is extended outside the case 1. Meanwhile the damper 21 is engaged with the gear rack 132 of the second channeling mechanism 13 to decelerate the motion so that the extendable deck 2 won't be moved out too quickly. Once the extendable deck 2 is completely outside the case 1, the slant bucking member 334 of the second hub 33 will be pushed by the slant surface of the sloped trough 112 of the face panel 11 to force the first and second hubs 32 and 33 to compress the torsional spring 34, and the hook 321 of the first hub 32 is moved from the trough 42 to the notch 421 on another side thereby the display panel holding mechanism 4 escapes the constraint of the hook 321 and the extendable deck 2 is completely moved outside of the case 1 to be anchored. The partition 31 of the coupling mechanism 3 is pushed by the returning elastic force of the torsional spring 34 and extended forwards to lift the display panel holding mechanism 4 upright so that users can see the LCD panel 40.
Referring to FIGS. 13, 14 and 15, adjusting and anchoring the viewing angle of the display panel is accomplished through the angle adjustment assembly 5B. In normal conditions, the springs D1 and D2 pull the sliding board 53 to make the LCD panel 40 in an upright position. The anchor push button 56 and the gear racks 552 and 571 of the anchor member 55 may be adjusted to different elevations to alter the angles of the sliding board 53 and the elevation angle push plate 58. Therefore user needs only to depress the anchor push button 56 and move the LCD panel 40 to a desired elevation angle, then release the anchor push button 56 to complete the angular adjustment. When the LCD panel is stored and unloaded next time, it automatically turns to the angle set previously. Thus it can remember the adjusted angle for later use.
In summary, the mechanical operation provided by the invention is less likely to incur malfunction, and can replace the expensive electronic circuit control, and can automatically and rapidly unload or retract and store the display panel. The viewing angle may also be adjusted to suit user's requirements. And once adjusted, the invention can remember the adjusted angle for later use.
