The balance member 96 has a sleeve 962 which is screwed and fixed to the front outer wall 943 of the frame 94, a sleeve 962 which is sleeved on the pivot 961, and a torsion spring 963 which is wound around the sleeve 962. The torsion spring piece 963 includes a fixed end located at the beginning of the innermost ring and fixedly attached to the surface of the sleeve 962 (not shown: no), and - located at the outermost ring and extendedly screwed to the plate-shaped sliding member 951 The outer fixed end 964, and the torsion spring 963 is constantly applied to the plate-like slider 951 - a force that is upwardly balanced with the downward gravity of the display 92. Therefore, when the user (not shown) manually applies the force to lower the display member shame to lower the display 92 to a predetermined height, once the user's hand is released from the extension member 95, the balance of the above-mentioned torsion elastic piece is balanced. In effect, the extension member %, along with the display 92, automatically stops at that height without further adjustments of 5 M302101. On the other hand, when the user applies a force to pull up the extension member 95 to raise the height of the display 92, the display 92 can be easily raised to a predetermined height with only a slight application of force. In general, such a structure for lifting and lowering adopts a structure similar to a telescopic sleeve of a telescope, occupying a large volume, and the visual effect is rather cumbersome and occupies an empty space, so how to reduce the size of such a lifting and lowering makes a flat panel display ^ Lightweight and flexible, it has always been the subject of the industry's desire to break through.

The clamping wheel set is long. When the square housing 45 swings up and down, it makes a synchronous rotation, and then the left and right sides and the right side are right, and the left and right clamping wheels 310 311 are sequentially away from the side of the rectangular body 45, each of which is respectively The left and right elastic top sheets 315 and 316, the left and right friction sheets 3〇〇, 3〇1, and the left and right positioning pieces 303 and 304 are attached, so that the convex cards 314 are inserted into the respective notches 39〇 to make each convex The card is inserted into the notch 302' and the two ends 460 of the set shaft 46 pass through the left and right elastic top sheets 315, 316, the left and right friction plates 3〇〇, 3〇1 hollow parts and the left and right positioning pieces The shaft hole 33 of 3〇3, 3〇4 is passed through the kidney-shaped groove, and the other locking group has a positioning bolt 47 at the locking hole 37, and the left elastic top piece 315 and the left friction piece 300 are not tightened to the left positioning piece. Between 3〇3 and the left clamping wheel 3ι〇, the right elastic top piece 316 and the right friction piece 301 are tightly between the right positioning piece 3G4 and the right clamping wheel 311, so that the entire friction device 4 is firmly positioned, such as Figure 9, rotating (four) bit screw inspection 47 can withstand the frictional resistance between the top annular flange (10) of the left and right elastic top sheets 315, 316 and the left: right friction plates 300, 3G1, and the four sets of the entire assembly * And the friction device 4, corresponding to the left 'right positioning piece ·, 3 〇 4 call the surface of the slightly elliptical card convex, edge 306, and together with the figure 10, placed in the top frame of the main frame The disc 24 is recessed in the facing surface 24 = = concave frame groove 241, and then each of the plug body 27 is inserted into the left and right positioning pieces 303 and the upper 4 middle shaft holes 34, so that the four link group 4 and the motor can be The resistance device 3 pivots the top tray 24 of the wood slave. The value emphasizes that the tray 24 is fixed, so the left and right positioning pieces 3G3 and 304 are also fixed, and the 10 M302101 is tilted. The film 3〇3, 304 does not move, so y* ★ and the day you are so the left and right friction plates 300, 301 do not move, thinking that the friction device 3 does not move, and then cooperate with Figure 1Q, four connected frame 2 draws ^, _ 连 #,,, 4 with two sets of axis 4 Θ as the pivot point, the right ejector top can drive the idling wheel set by the rectangular shell 45 and interlock the left 曰 5 top piece yang, rotate , meaning friction of the friction device 3 31 = δ: the four-bar linkage 4 is interlocked, so the left and right elastic top sheets 315, 316 are combined with the left and right friction plates _, the viewing contact surface 提供 to provide an appropriate Tightening resistance. 4, the adjustable tensioning device 5 is composed of a _string group 52, an elastic element group 53 and a regulator 54; the rope group 52 is pulled by the left and right ropes. The first end is provided with a positioning block 52〇, and the other end is set to be a circle 52. The left and right drawstrings are correspondingly wound around the left and right clips, and the 311 is recessed along the circumference of the top curved arc. The groove π, the positioning block 520 ' is further positioned as shown in FIG. 7 ' buckled in the buckle groove 35 , and the elastic element group 53 is composed of left and right stretched elastics, and each end is a hook end 53〇. Each of the other ends is formed as a loop-shaped end 531, and the hook-shaped end 53 is correspondingly hooked to each of the drawstring hooks 521 of the drawstring group 52; the adjuster 54 is composed of a hook block and a screw 541. A hook 542 is formed on each side of the hook block 54. The left and right tension spring loop ends 531 of the elastic τ 件 group 53 are correspondingly hooked on the hook handle 542, and the hook block 54 is vertically threaded with a screw hole. 543, the screw 541 is a screw group passing through the screw hole 26 of the main frame body block 26, and then screwed through the screw hole 543 of the hook block 54. The carrier 6' is further referenced to FIG. 8 and is pivotally disposed on a short rod group 43 of the four-bar linkage 4 protruding from the outside of the rectangular housing 45, that is, pivoted away from the four 11 M302101 linkage group. 4 and the friction device 3, the end portion 41 pivoting seat 6〇, the carrier 6 for assembling the object is the assembly-liquid crystal curtain. Under normal conditions, 'match the map! The weight f of the object i causes the connection of the two sets of shafts 46 as the pivot point. When the rectangular casing 45 drives the clamping wheel set to rotate, the drawstring set 52 is pulled. Stretching upwards, the elastic m group 53 is stretched and stored, and the clamping wheel set rotates while the left and right elastic top sheets 315'316 are rotated together with the drawing of FIG. 9 and FIG. 10, so the left and right elastic top sheets 315 316' respectively provides friction with the contact surface a of the left and right friction plates 3〇〇, 3〇1 to provide a proper pressing resistance. When this frictional resistance is not considered, There are three conditions that may occur. 'The first type is when the weight F of the object 大于 is greater than the tensile force of the elastic element group ^, then the object 1 is always lowered at the lowest position, and the second is when the weight F of the object 1 is just at When the manufacturing is controlled to be equal to the tensile force of the elastic member group 53, the object 丨 will always stop at the desired position, and the third is when the weight F of the object 1 is smaller than the tensile force of the elastic member group 53. The object 1 is always pulled up at the highest position. Although the three conditions are ideal in the second form, they are also desired by the manufacturing industry. However, it does not mean economic benefits, because the weight I of the object i must always be controlled by the same weight. When it is difficult to control, only a single specification can be used. Generally, the weight error of a single specification is not too large, so the different weight items are matched. Different elastic component groups 53 are used to match the manufacturing industry, and the inventory will increase, so the cost will increase. This is not the industry's favorite, and the first one is not ideal, because the elastic component group 53 will be in the whole process. The middle is stretched in the most extreme state, the elastic fatigue is sure to occur, and finally the elastic balance will fail. Of course, if the above left and right elastic top sheets 31 $, 316 12 M302101 are respectively used, the side top annular flanges 39 with the left and right friction plates, 3 〇 ι = face A for friction - appropriate resistance to adjust the balance so that the object will ik = = in the desired position 'but permanent use of this resistance will also make the friction The function of the resisting device 3 has a depleted period, so the most desirable state is the third type, and the weight of the object 1 is controlled to be smaller than the range of the tensile force 4 of the elastic member group 53, and then with a little such contact ^ rubbing the resistance, the object can be permanently controlled in the desired position for positioning at any time, Figure 2 2, Figure 3, (4) When the screen is raised or lowered, you can stop at any time, as for the object] The position adjustment of the upper and lower parts, as shown in Fig. 14 and Fig. 15, is the fact that the four-link group 4 is used to achieve 'is an indisputable fact, and no further explanation is given here. As described above, since the left elastic top sheet 315, the left friction piece positioning piece 303 and the left clamping wheel 31〇, the right elastic top piece 3i6 and the right friction piece 3〇1 are clamped to the right positioning piece m and the right clamping wheel 311. Between, so when to increase or decrease / around the top 315, 316 and the left and right friction plates to suppress the frictional resistance of the touch surface A, then refer to Figure 9, as long as the screw is loosened or loosened 47 can be adjusted, very convenient, for example, when assembling a lighter object i, it can be loosened, so that when the displacement is adjusted, the light weight is not too great, and when assembling a heavier object! When it is time to tighten, when it is used for displacement adjustment, it can be adjusted to maintain the position at the desired position. When the tensile force of the elastic element group 53 is finely adjusted in the field, in the case of FIG. 11, the rotating screw 541 is displaced downward, and as shown in FIG. 6, the hook block 540 is displaced downward to enhance the elastic element group. The tensile strength of 53 can carry heavier objects. When the displacement is upward, the 'hook block 54{) is synchronously moved upward, and then returns to the figure 11. The tensile force of the elastic component group 53 is reduced, and the lighter object can be carried. , 13 M302101 Easy adjustment for applicable. - Object 1 = The new type can be adjusted by the four-bar linkage 4 so that the Nissan linkage and the lower displacement material (4) are placed together (4), and the adjustable tension device is pulled by the same 1 = and the attack 3 5, provide - pull: 31 pairs: 1 piece of gravity preliminary balance 'further by the friction device of the friction device 3 yak 30 to provide a suitable friction resistance assistance, as soon as the position is positioned. ^ The above description is only for the preferred embodiment of the present invention.
