Description

PIVOTAL ROTATION ADJUSTMENT APPARATUS FOR FLAT PANEL DISPLAY DEVICE BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION The present invention relates to a flat panel display device such as a liquid crystal display (LCD) for a lap top computer and a plasma panel display (PDP) device and more particularly, for a rotation adjustment apparatus pivotal for an improved flat panel display device that allows a display screen section to be adjusted horizontally, as well as vertically, thereby minimizing an unbalanced weight condition and providing an increase in visibility. 2. DESCRIPTION OF THE BACKGROUND TECHNIQUE With reference to Figures 1 and 2, a conventional apparatus for adjusting a pivotal rotation of a display device of a flat panel includes a fixed frame 110, a vertical rotation arrow 120, a pair of vertical rotation frames 130 and an arrow fixed 140 A through hole 110b is formed, which passes through the fixed frame 110 from side to side along a front edge thereof and a first recess 110c which is formed in a central portion of the fixed frame 110. As shown in FIG. 2, the bolts 120a extend axially from each end portion of the vertical rotation shaft 120, this shaft 120 is rotatably carried in the through hole 110b in the fixed frame 110. Here, the bolts 120a are formed smaller in diameter that the vertical rotation arrow 120. A concealed hole 130a is formed in a portion of the inner end of each of the vertical rotation frames 130, 130 in front of the fixed frame 110 and the pins 120a are correspondingly pressed into the concealed holes 130a . Here, a display screen section (not shown) as an LCD monitor is fixed in the vertical rotation frames 130, 130. That is, the vertical rotation frames 130, 130 are rotatably fixed on the left and right sides of the frame fixed 103 through the vertical rotation arrow 120. Meanwhile, as shown in Figure 1, a first protrusion 140a formed at the upper end of the fixed arrow 140, is fixed in the first recess 110c of the fixed frame 110, whereby the fixed arrow 140 is fixed vertically in the fixed frame 110. The fixed arrow 140, fixed in the fixed frame 110, is fixedly inserted in a base pad (not shown) to mount a display device in a upper portion of the base pad (not shown). The conventional pivotal rotation adjustment apparatus thus constituted for a flat panel display device allows the user to vertically tilt a section of the display screen. Specifically, as the vertical rotation arrow 120 independently rotates, the vertical rotation frames 130, 130 that hold the display screen section in a fixed manner, move up and down. However, although the conventional rotation adjustment apparatus for a flat panel display device allows the adjustment of the tilt angle in its upward and downward movement, it is impossible to adjust a horizontal rotation angle. In addition, due to the own weight of the section of the display screen, when the section of the screen is tilted, the base pad that holds the section of the screen can oscillate, so that the equipment can lose balance or even fall . Furthermore, the inclination of the section of the screen can not maintain a constant angle due to the weight of the section of the screen.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Now the pivotal rotation adjustment apparatus for a flat panel display device according to the present invention will be described. As shown in Figures 3 to 5, a fixed frame 10 includes a protrusion of guides 10a, extending from a rear end portion thereof, a hole 10b formed in each side surface of the front thereof. and a first recess 10c formed in the bottom center thereof. With reference to Figure 4A, a pair of vertical rotation arrows 20, 20 are pivotally inserted in the holes 10b, 10b on the sides of the fixed basestation 10 and each is appropriately surrounded by a friction sleeve 21. A bolt 20A is It extends from one end of each vertical rotation arrow 20, 20. Here, the planes 20a are smaller in diameter than the vertical rotation arrows 20, 20. As shown in Figure 4B, instead of two holes 10b, 10b shown in Figure 4A, a single-pass hole 10b'can be formed in the fixed frame 10 ', whereby only one vertical rotation arrow 20' is required. The reference numeral 20a 'in FIG. 4B represents a vertical rotation arrow. In this way, the preferred embodiment of the present invention can employ either one or two vertical rotation arrows, which has an identical function and in case of using the single arrow 20 'a single friction sleeve can be used on the arrow of vertical rotation 20 '. A pair of vertical rotation frames 30, 30 respectively arranged to the right and left of the fixed frame 10 are installed to hold a section of the display screen like an LCD monitor in front portions thereof. A couple of hidden holes 30a, 30a are respectively formed on the side surfaces thereof facing the fixed frame 10, and the bolts 20a, 20a of the arrow 20 are fixedly inserted therein. That is, the vertical rotation frames 30, 30 are mounted on the vertical rotation arrow 20 (20 '). Also, as shown in Figure 3, a horizontal rotation arrow 40 is fixed to the bottom of the fixed frame 10, and a support flange 40b is provided at the upper end of the horizontal rotation date 40. A protrusion 40a extends upward of the support tab 40b. A threaded portion 40c is formed at the lower end of the horizontal rotation arrow 40. The protrusion 40a is fixedly inserted into the first recess 10c in the fixed frame 10, whereby the horizontal rotation arrow 40 is fixedly connected to the fixed frame 10. According to the foregoing, the fixed frame 10 conforms to the horizontal rotation arrow 40.

As shown in Figure 6, a plurality of support members 50 are carried in the horizontal rotation arrow 40, which is fixed to the fixed frame 10. As shown further in Figure 7, an annular friction sleeve 61 is provides between the outer periphery of the horizontal rotation arrow 40 and the respective internal peripheries of the ends of the support members 50. Specifically, the annular friction sleeve 61 is for facilitating rotation of the horizontal rotation arrow 40 independently, without with respect to the support members 50. As a result, the support members 50 are not rotated, although the horizontal rotation arrow 40 makes an independent rotation. Figure 7 shows a detailed view of the support member 50. As shown therein, the support member 50 includes an annular portion 50a and a wing portion 50b. The annular portion 50e is formed by folding an end portion of the support member 50, where the wing portion 50b radially extends from the annular portion 50a in the form of a hinge plate. With respect to the adjustment between the horizontal rotation arrow 40 and the support members 50, the annular portions 50a of the support members 50 are installed on the horizontal rotation arrow 40 of the lower end thereof, whereby the plurality of support members 50 can be aligned side by side along the horizontal rotation arrow 40. At this time, the respective adjacent wing portions 50b extended from the annular portions 50a extend to the alternating sides of the horizontal rotation arrow 40. Subsequently, as shown in Fig. 6, a fixing sleeve 60 is screwed into the threaded portion 40c at the lower end of the horizontal rotation arrow 40. As shown in Fig. 8, the support members 50 adjusted in the horizontal rotation arrow 40 they form an arc between the base housing 70 and the housing cover 71. The base housing 70 and the housing cover 71 They are held together by screws. The mechanism between the base housing 70 and the horizontal rotation arrow 40 will now be described. A plurality of transverse ribs 70b with semicircular notches therein is formed in the interior of the base housing 70 and a plurality of longitudinal ribs 70c are formed in an adjacent pattern inclined on both sides of the transverse ribs at 70b. Grooved overhangs 70d are formed at intersections of the transverse ribs 70b with the longitudinal ribs 70c in the base housing 70 in a stepped manner and receives the screws 72 therein by screws 70, to fit the base housing 70 to the cover 70. housing 72. A corresponding plurality of screw holes 71a is provided in the housing cover 71 to allow the screws 72 to pass therebetween and within the corresponding threaded lugs 70d.

To secure the housing cover 71 on the base housing 70 using the screws 72, a peripheral surface of each annular portion 50a and a peripheral surface of the fixing sleeve 60 abut a semicircular notch in the corresponding one of the transverse ribs 70b in the base housing 70 and one side of the corresponding wing portion 50b abuts the corresponding one of the longitudinal ribs 70c. The opposite peripheral surface of the annular portion 50a and the opposite peripheral surface of the fixing sleeve 60 abut the respective semicircular notch formed in the corresponding transverse ribs (not shown) in the housing cover 71., which is similarly provided with corresponding transverse ribs 70b and the longitudinal ribs 70c. The threaded lugs 70d arranged in an inclined pattern in the base housing 70 are raised between the wing portions 50b of the support members 50 to coincide in the screw holes 71a. Correspondingly, the screws 72 are inserted into the holes of the screws 71a and screwed into the corresponding lugs 70d, whereby they are fixed to the housing cover 71 in the base housing 70. In accordance with the foregoing, the rotation arrow horizontal 40 is pivotally disposed between base housing 70 and housing cover 71, support members 50 form an arc in a fixed manner between base housing 70 and housing cover 71. Support flange 40b of arrow horizontal rotation 40 serves to hold the support members 50 in place and is placed on the surface of the upper end of the base housing 70 and in the housing cover 71. As shown in Figs. 8 and 9, an arcuate groove 70a is form on the upper surface of the base housing 70 and serves to receive and guide therein the extended guide protrusion 10a of the lower surface of the fixed frame 10. E That is, the guide protrusion 10a is movably inserted in the arcuate groove 70a, whereby the pivotal movement of the display screen section (not shown) can be restricted within - an appropriate angular scale, whereby the adjustment of a rotary angle of the display screen section (not shown) is facilitated. The arcuate groove 70a may have one or more detents at angular intervals along the same. Here, the reference number 30b represents a fixing portion of the vertical rotation frames 30 to which the screen section (not shown) is fixed. The pivotal rotation adjusting apparatus, thus constituted, for a display device of a flat panel according to the present invention allows the user to vertically adjust the section of the screen (not shown) mounted on the vertical rotation frames. , 30 in a manner in which the vertical rotation arrow 20 'rotates pivotally and in accordance with the above the vertical rotation frames 30, 30 are inclined upwards and downwards.

As described above, when the display screen section (not shown) is adjusted upwards or downwards, the friction sleeve 21 (21 ') surrounding the vertical rotation arrow (20) 20' is fixedly inserted in the vertical rotation frame 30 through the fixed frame 10 (10 ') provides a frictional fit against the inner periphery of the holes 10b, 10b (or the through hole 10b') of the fixed frame 10 (10 '), so that it tilts pivotally and stably the section of the screen (not shown) and minimizes the oscillation of the screen section (not shown) resulting from its own weight, while constantly maintaining the angle of inclination of the section of screen (not shown). In addition, the pivotal rotation adjustment apparatus for a flat panel display device in accordance with the present invention allows the user to tilt the section of the screen (not shown), mounted on the vertical rotation frames 30, 30 toward the left or right so that the fixed frame 10 fits the vertical rotation frames 30, 30 and can rotate horizontally together with the pivotal rotation of the horizontal rotation arrow 40. When the section of the screen (not shown) In a movement to the right or to the left, the plurality of the support members 50 assembled in a zigzag pattern in the horizontal rotation arrow 40 serves to support the pivotal rotation of the horizontal rotation arrow 40 and the pivotal rotation of the the horizontal rotation arrow 40 is further guided by the fixing sleeve 60 carried to the lower end of the horizontal rotation arrow 40. Also, when the fixed frame 10 makes a movement to the right or to the left in accordance with the rotation to the right or to the left of the section of the display screen, the extended boss 10a of the rear portion of the bottom of the frame fixed 10 is guided within the acute guide groove 70a formed in the upper surface of the base housing 70, whereby an angle of rotation of the display screen section is adjusted. That is, the horizontal rotation of the section of the display screen is smoothly adjusted, a result of the function of the support members 50 and the guide protrusion 10a, whereby it restricts a possible oscillation of the screen section due to its own weight. As described above, the pivotal rotation adjustment apparatus for a flat display device in accordance with the present invention allows an effective adjustment of the horizontal rotation angle, as well as the vertical rotation angle of the display screen section. In addition, the pivotal rotation adjustment apparatus for a display device in accordance with the present invention, having a friction sleeve surrounding the periphery of the vertical rotation arrow and the support members carried on the horizontal rotation arrow in an inclined pattern, prevents the display screen section, the base housing and the vertical rotation frame from oscillating during the rotation movement and all the equipment of the device being shaken, so that the total assembly is stabilized. Since the present invention can have several forms of modalities without departing from the essence of the essential characteristics thereof, it should be understood that the modalities described above are not limited by any of the details of the previous description, except for those specified in another way, but they must be broadly designed within their essence and scope as defined in the appended claims, and therefore all changes and modifications that are included within the requirements and limits of the claims or equivalences of said requirements and limits. they will be covered by the appended claims.
