The effect of the orientation of the unit's decorative plate. Please refer to FIG. 1A to FIG. 3B; the stencil unit proposed by the present invention comprises a plate body 1 1 , a stencil 1 2 , a weight member 13 and a sliding handle 1 1 5 , wherein the plate body 1 1 is a carrier plate 1 2. The main carrier plate of the weight member i 3 and the sliding handle 5, in the specific embodiment, the front plate surface of the plate body is provided with a decorative plate receiving portion 1 1 3 and corresponding decorative plate capacity. The through slot 1 1 4 'the slide rail 1 1 5 is disposed on the plate body 1; [the rear plate surface 1 1 2 (as shown in FIG. 1B); and the decorative plate 2 is pivoted on the decorative plate. In part 3i 3, the decorative soil 2 is composed of a decorative version 2 1 and a mounting portion 1 2 2 extended by the decorative version 丄 2丄, a golden version! The 2 working system can be placed in the decorative part 1 1 3, and the mounting part 2 2 is protruded by the slotting work 4 to the board after the board 1 1! ! 2, to correspond structurally to slippery 1 15 . Decorative version! 2 Works can be printed with text, drawings, 丨〇§〇 or trademarks. On the other hand, the installation department 2 2 provides a specific living impurity 15 for the weighting device 3, and the range of motion is mainly from the wire crossing portion 2 7/22 201244481 2 A and the installation crossing portion 1 2 2 A is formed by an extended chute 1 2 2 B extending obliquely to both sides. Specifically, the extended chute 丄 2 2 B is formed by obliquely extending from both sides of the women's crossing portion 1 2 2 A toward the decorative version 1 2 1 . It is important to note that any other means sufficient to displace the weight member 13 within a particular range of motion is within the scope of the mounting section 丄2 2 . Furthermore, the weight member 13 is movably mounted on the mounting traversing portion 1 2 2 A of the mounting portion 2 2 2, and the weight member 23 affected by the external force can be extended by the mounting traversing portion 1 2 2 A Slot 1 2 2 B slides, or slides back from the extended chute 1 2 2 B to install the traversing part 2 2 A. The above-mentioned (7) 1 1 5 corresponds to the weight member 13 , so that the weight member 13 abuts against the slide rail 15 , and the slide rail 1 15 is provided with a protrusion 15 adjacent to at least one end thereof. 1. When the weight member 13 is movable within a defined range in which the traversing portion 1 2 2 Α and the extension chute 1 2 2 安装 are installed, the weight member 丄 3 is pivoted at the center of the garnish receiving portion 1 1 3 Arc shift. As shown in Fig. 2, in the present embodiment, the pivot center between the weight member 13 and the decorative version 1 2 1 (i.e., the pivot 2 3 and the shaft member 1 described later) At the assembly point of 24), the upper jaw 5 is a (4) (four) which is read along the pivot and is substantially recorded, and the length and curvature of the guide are designed according to the size of the body 11. When the shame 1 1 is larger, the sled i i 5 needs to be designed longer. The pivot center between the weight member and the decorative version 121 is divided into four quadrants = one quadrant respectively occupying a range of 45 degrees radians, and the slippery 15 is 5 and is placed in one of the four quadrants. On the same day, Fengpansi 1 ! r from ", U f / month, the overall length of 1 1 5 is also roughly limited in this quadrant. The two endpoints of 1 of 5 of slippery 1] 5 are defined as 8/22 201244481 One end 115A and the second end ιΐ5Β. Slipper 1 1 5 can be placed adjacent to the first end 丄丄 5A, the second end of the work 5 B respectively with a raised part!! 51. In the general state (please cooperate Fig. 3A and Fig. 3B), the stencil 1 2 and the weight 丄 3 are combined so that the stencil 1 2 will be subjected to the forward gravity sway of the weight 丄 3, and the decorative plate 1 2 is in the forward orientation (ie, the 丄2 observed by the user is in the correct text or pattern orientation). Figure 4 a shows the position of the weight member 丄3 in the normal state (such as the upright state); The body i 1 is shown by Fig. 4Am: when the angle changes by the aspect (for example, starting to pour the entire casing), but the angle change is less than - the predetermined angle (ie, the critical angle), the dizzy The weight of the heavy-duty version of the body i 2 itself and the reaction of the bulge work to the weight member 13 are not sufficient to return the weight member 3 into the extension chute 1 2 2 B. In other words, the direction of the opening of the extending chute 122_ obliquely extending from both sides of the mounting traverse portion 2 2 a is also a limiting condition - the opening direction of the extending chute 丄 2 2 B must face the convex portion 1 1 One of the sides (when the weight member 丄3 is located at the first end 5 A, the first end; [丄5 B, the direction of the extended chute 1 2 2 β at both ends corresponds to the different convex portion 1151 The side surface), so that when the angle fk exceeds the critical angle, in the decorative version body 2 2 ^ , based on the reaction force of the convex portion 1151 on the weight member 13, the weight weight member 13 is pushed into the extension slide The groove 1 2 2 β. • Before the weight “f” is smaller than the predetermined angle (ie, the critical angle), the distribution of the cattle 1 3 is still at the installation crossing point 1 2 2 A, so the weight of the work piece 3盥 version of the body...

In other words, the convex portion 1 of the adjacent MSRA of the adjacent rail US is generated by the gravity of the counterweight η = non-positive orientation (ie, the orientation or pattern orientation of the slanted by the user at this time = 2 gray slanting, such as Figure coffee)). The angle 2=1 continues to produce an angle change and is greater than the predetermined angle (as shown in FIG. 4C_a), and based on the reverberation of the version body 121 itself, the reaction (10) based on the protrusion 1151 on the weight member is made. The weighting component 1 3 is slid along the extension/lunar 1 2 2 安装 by the mounting traversing portion 1 2 2 8 to shorten the distance between the weighting member 13 and the pivoting center of the # version 2 ( (for example, 2BiU is shortened to (2), and ^ is the distance L2 is smaller than the distance L3 between the convex portion 1 1 5 1 and the pivoting center of the decorative version 2, and the weight member 丄3 is crossed (4) 丄丄 5 1 The obstacle formed in the height, and slides along the slippery 5. Since the part of the space where the traversing portion 1 2 2A is installed will slightly protrude t, the kidney holds the sliding area S of 1 1 5 (as shown, Adjacent to the first - creep. 1 1 5 A, the second end! The area between the raised portion i5丄 of i 5 B,) 'the space that causes the An Zhen to cross the part 2 2 A is reduced, and after the reduction The space is slightly smaller than the connecting cylinder of the weight member 丄3 i 3 2 3 = outer! (ie, the column between the bolt head 丄 3 2 i and the bolt connection P 1 3 2 2 described later) ), so as to pass through the space formed by the installation traversing part 1 2 2 A and the extended chute 丄2 2β, plus the moving 10/22 201244481 heavy piece 13 with centrifugal force, making the weight 丄3 impossible During the movement in the sliding region s of the slide rail 5, the crossing portion 丄2 2 A is installed and held in the extension chute 1 2 2 B. Under this condition, the weight of the weight member 13 is divided. The force is greater than the supporting force formed by the convex portion 1151, so that the weight member 13 can slide along the convex portion 1 1 5 1 along the sliding workman 5 to drive the decorative plate 1 2 relative to the plate body: Rotate to the positive direction (ie, the 丄2 observed by the user at this time is in the correct text or pattern orientation, as shown in Figure 4c_b). When the slab 11 reaches the end of the angle change (as shown in Figure 4D_a) The flip is 9 degrees, that is, lying down, because the distance L2 between the weight member 13 and the decorative body χ 2: pivot center is smaller than the pivot 丄丄5丄 and the hinged version of the limb 1 2 1 The distance u between the centers of revolutions causes the weight member 丄3 to pass through the boss portion 1151 adjacent to the second end USB. After the weight member 13 passes the protrusion σΡ 1 1 5 1 , The weight 13 is affected by gravity, and the weight member 13 can be slid back from the extension chute 1 2 2 B to the installation traversing portion 2 2 A ', so that the weight member 13 is located at the second of the slip 1 1 5 End i 1 5 B 'At this time, the stencil 丄 2 is rotated to a positive orientation with respect to the slab ( (ie, the stencil 2 observed by the user at this time is in the correct text or pattern orientation, as shown in FIG. 4D- b)), in contrast, when the plate body 1 1 is changed from the flat position in the reverse direction of the position of FIG. 5A to the upright state), the change in the angle is small; and the μ is a predetermined angle (ie, the critical angle). Next, adjacent to the slide rail 1 1 5 = the first known 1 1 5 Β convex portion 1 1 5 1 can make the decorative plate 1 2 in the orientation direction (that is, the decorative plate 1 2 observed by the user at this time is located in the skewed text) Or the orientation of the pattern, as shown in FIG. 5B_a and FIG. 5B_b), and the position of 11/22 201244481 * · ' · of each member can refer to the foregoing content; until the plate body 11 continuously produces an angle change and a predetermined angle, the weight member 13 It can be slid across the raised portion 1151 by the π rail 1 1 5 to drive the feeding plate 2 to rotate relative to the plate body to the positive direction ( That is, the user observes the decorative plate 1 2 at the correct text or pattern orientation, as shown in Fig. 5C_a, Fig. 5〇b); 1 reaches the end point of the angle change 'the weight member 1 3 can be extended two: 2 B 'month back to the women's cross section 1 2 2 A, and make the weight 1 =:? the first end 115A of the slip 115, and the 12 phase, & 1 and rotate to a positive orientation (Figure 5D_a, shown in Figure 5D_b). In the towel of the embodiment, the predetermined angle is about °, and the plate body 1 of the embodiment of the present invention needs to be rotated more than 45. , = only: start to rotate. And a variation of the first embodiment of the embodiment rail 1 1 5 1 ! R Δ junction _ & 5 Α, the first 鸲 115 Β convex portion has a different protrusion height ' and the two extension slots 2 angle = ΓΓ extension length, so when the plate body 11 is not = 匕 'the critical angle at which the stencil 12 starts to rotate is different (due to the bulge.) 151 The height obstacle formed by the 151 is different. The slider 11 5 may be provided with a convex portion 1151 only adjacent to the first end 115. When the plate body is produced, the angle change is less than - predetermined two, the convexity of the adjacent sliding (1), ... 1 can make the decorative plate 1 2 in the non-positive ancient γ B 115 peach version fly 9仂ρ λ± direction (that is, the user observes the 12-position, oblique text or pattern orientation); When the ground body 1 1 continues to cover the angle of change and the height of the plate is 8 π 疋 top angle, the weighting device 12/22 201244481 3 can slide across the bulge 1 1 5 1 along the sliding 1 1 5 , thereby Driving the decorative plate 1 2 relative to the plate body 1 旋转 and rotating to a positive direction (ie, the user is viewing the decorative plate 1 2 in the correct text or pattern square position) At the same time, the weight member 13 can be slid back to the Ansuo tooth portion 1 2 2 A by the extension chute 1 2 2 B, so that the weight member 13 is located at the second end of the slide rail 1 1 5 1 1 5 B This part is the same as the foregoing description. Conversely, since the second end 丄丄5B adjacent to the slide rail 1丄5 has no design of the protrusion 邛1 1 5 1 , the angle change in the opposite direction of the board body 1 1 At this time, the weight member 13 can immediately produce the effect of sliding along the slide rails 5, thereby driving the decorative plate 1 2 to rotate synchronously to a forward orientation with respect to the plate body 1 i. In addition, in the foregoing two embodiments The extension chute 丄 2 2 B on both sides of the installation traversing part 丄 2 2 A can provide the effect of reducing the size of the slippery 丄χ 5, as shown in Fig. 1, Fig. Β and Fig. 2Β, the version 饰 2 1 is substantially a circular plate body, and the decorative plate accommodating portion 3 is a circular accommodating groove, and the decorative version i 2 i is made of a pivot 丄 2 3 ' pivot member 2 4 and a decorative plate The engagement of the pivot hole χ丄3丄 in the portion 1 ! 3 is pivoted to the garnish receiving portion 1 1 3 , and the position of the extended chute 1 2 2 B is relatively close to the mounting traversing portion ^ 2 2 a The version of the body ^ 2 1 is pivoted (ie, the assembly of the pivot 1 2 3 and the pivot member 1 2 4), as shown in Fig. 2B, the distance between the mounting traversing portion 1 2 2 Λ and the pivot center is [丨, and the extension chute 1 2 2 B The distance between the end and the pivot center is L2, and u is greater than L2'. Therefore, the weight member 13 is slid from the mounting traverse portion 1 2 2 A to the extension chute 1 2 2 B, and the weight member 3 can have a smaller The radius of rotation is such that the size of the slider 1 15 can be reduced.
