For a better understanding of the features and technical aspects of the present invention, reference should be made to the accompanying drawings.

The invention provides a stencil unit and a casing thereof, wherein when the casing produces an angle change, the stencil of the stencil unit can synchronously generate a corresponding angular change, more specifically, when the casing produces an angle change, In the case where the angle of the casing changes less than a critical angle, the decorative plate of the decorative unit maintains the original orientation until the angle of the casing changes by more than a critical angle, and the orientation of the decorative plate of the decorative unit is rotated to a positive orientation (ie, when the angle change of the casing is equal to a critical angle, the decorative plate of the decorative unit begins to rotate) to form an effect of automatically adjusting the orientation of the decorative plate of the decorative unit as the angle of rotation of the casing is rotated. .

Please refer to FIG. 1A to FIG. 3B; the stencil unit proposed by the present invention comprises a plate body 11, a stencil 12, a weight member 13 and a slide rail 115, wherein the plate body 11 is a carrier plate 12, a weight member 13 and The main carrier of the slide rail 115. In the embodiment, the front surface 111 of the plate body 11 is provided with a decorative plate receiving portion 113 and a through groove 114 corresponding to the decorative plate receiving portion 113. The sliding rail 115 is disposed on the plate. The body 11 is followed by a plate surface 112 (FIG. 1B); and the decorative plate 12 is pivotally disposed in the decorative plate receiving portion 113, and the decorative plate 12 is supported by the decorative version 121 and the mounting portion 122 extending from the decorative version 121. The decorative body 121 is pivotally received in the garnish receiving portion 113, and the mounting portion 122 is protruded to the rear surface 112 of the plate 11 by the through groove 114 to structurally correspond to the sliding rail. 115. The version 121 can be printed with text, drawings, logos or trademarks. On the other hand, the mounting portion 122 provides a specific range of motion for the weight member 13, which is mainly constituted by the mounting traversing portion 122A and the extending chute 122B extending obliquely from the mounting traverse portion 122A toward both sides. Specifically, the extension chute 122B is formed by obliquely extending from the both sides of the mounting traverse portion 122A toward the stencil 121. It should be particularly noted that any other means sufficient to displace the weight member 13 within a particular range of motion is within the scope of the mounting portion 122.

Furthermore, the weight member 13 is movably mounted on the mounting traverse portion 122A of the mounting portion 122, and the weight member 13 affected by the external force can be slid by the mounting traverse portion 122A toward the extending chute 122B, or by the extended chute. 122B slides back to install the traversing portion 122A. The aforementioned sliding rail 115 corresponds to the weight member 13, so that the weight member 13 abuts against the sliding rail 115, and the sliding rail 115 is provided with a convex portion 1151 adjacent to at least one end thereof. When the weight member 13 is moved within the defined range of the mounting traverse portion 122A and the extension chute 122B, the weight member 13 is angularly displaced by the garnish receiving portion 113 as a pivoting center point.

As shown in FIG. 2A, in the present embodiment, centering on the pivot center between the weight member 13 and the trim body 121 (i.e., the assembly of the pivot 123 and the pivot member 124 described later) In view, the slide rail 115 is a guide rail extending along the pivot center and substantially arc-shaped, and the length and curvature of the guide rail are designed according to the size of the plate body 11. When the plate body 11 is larger, the slide rail 115 needs to be designed to be longer. The pivot center between the weight member 13 and the decorative version 121 is divided into four quadrants (each quadrant occupies a range of 45 degrees of arc), and the slide rail 115 can be disposed in one of the four quadrants. At the same time, the overall length of the slide rail 115 is also substantially limited to this quadrant. The two end points of the slide rail 115 are defined as a first end 115A and a second end 115B, respectively.

The sliding rail 115 can be respectively provided with a convex portion 1151 adjacent to the first end 115A and the second end 115B. In the normal state (please cooperate with FIG. 3A and FIG. 3B), the stencil 12 and the weight member 13 are combined so that the stencil 12 will be pulled by the positive gravity of the weight member 13, and the stencil 12 In the forward orientation (ie, the decorative sheet 12 observed by the user is in the correct text or pattern orientation), FIG. 4A shows the position of the weight member 13 in the normal state (eg, an upright state); when the panel 11 is shown in FIG. 4A The illustrated aspect produces an angle change (eg, begins to pour the entire casing), but before the angle changes less than a predetermined angle (ie, a critical angle), the gravity and bulge of the decorative version 121 of the weight member 13 can be drawn. The reaction force of the portion 1151 against the weight member 13 is not sufficient to force the weight member 13 to slide into the extension chute 122B. In other words, the opening direction of the extending chute 122B extending obliquely from both sides of the mounting traversing portion 122A is also one of the limiting conditions, and the opening direction of the extending chute 122B must face one of the two sides of the convex portion 1151 (when When the weight member 13 is located at the first end 115A and the second end 115B, the opening direction of the extending slots 122B at the two ends corresponds to the side of the different protrusions 1151, so that when the angle changes beyond the critical angle, the decorative version Under the influence of the gravity of the body 121 itself, the counterweight 13 is pushed into the extension chute 122B based on the reaction of the boss 1151 against the weight member 13.

Before the angle change is less than the predetermined angle (ie, the critical angle), the weight member 13 is still at the mounting crossing portion 122A, so the pivoting center of the weight member 13 and the decorative version 121 (ie, the pivot 123 described later) The distance from the assembly of the pivot member 124 is L1 (as shown in FIG. 2B), and because the distance L3 (shown in FIG. 2A) between the convex portion 1151 and the pivot center of the decorative version 121 is smaller than L1. As a result, the movement of the weight member 13 is still blocked by the boss portion 1151, so that the weight member 13 cannot slide across the boss portion 1151. In other words, the raised portion 1151 of the first end 115A of the adjacent rail 115 can provide a supporting force against the force generated by the weight of the weight member 13 (as shown in FIG. 4B-a), so that the decorative plate 12 is located in a non-forward direction. Orientation (i.e., the orientation of the text or pattern that the user observes at this time is in a skewed text or pattern, as shown in Figure 4B-b).

When the plate body 11 continues to produce an angular change and an angle change greater than a predetermined angle (as shown in FIG. 4C-a), the reaction force of the weight portion 13 based on the convex portion 1151 is exerted under the influence of the gravity of the decorative body 121 itself. The weight member 13 is slid along the extending chute 122B by the mounting traverse portion 122A to shorten the distance of the weight member 13 from the pivot center of the decorative version 121 (for example, shortened from L1 to L2 in FIG. 2B), and Since the distance L2 is smaller than the distance L3 between the convex portion 1151 and the pivot center of the decorative body 121, the weight member 13 is slid along the sliding rail 115 across the obstacle formed by the height formed by the convex portion 1151. . At this time, since the partial space of the mounting traverse portion 122A slightly protrudes from the sliding region S of the slide rail 115 (as shown in FIG. 2B, that is, the region between the convex portion 1151 adjacent to the first end 115A and the second end 115B) The space causing the installation of the traversing portion 122A is reduced, and the reduced space is slightly smaller than the outer diameter of the connecting cylinder 1323 of the weight member 13 (ie, the bolt head 1321 and the bolt connecting portion 1322 described later are connected). The intermediate cylinder) passes through the space formed by the installation traverse portion 122A and the extension chute 122B, and the moving weight member 13 carries centrifugal force, so that the weight member 13 cannot be in the sliding region of the slide rail 115. During the movement in S, the installation traversing portion 122A is entered and remains in the extension chute 122B. Under this condition, the weight component of the weight member 13 is greater than the supporting force formed by the boss portion 1151, so that the weight member 13 can slide along the sliding rail 115 across the boss portion 1151, thereby driving the decorative plate 12 relative to each other. Rotating to a positive orientation on the panel 11 (i.e., the stencil 12 observed by the user at this time is in the correct text or pattern orientation, as shown in Figure 4C-b).

When the plate body 11 reaches the end point of the angle change (flip 90 degrees as shown in FIG. 4D-a, that is, the lying state), since the distance L2 between the weight member 13 and the pivot center of the decorative version body 121 is smaller than the convex portion 1151 The distance L3 from the pivoting center of the decorative version 121 enables the weight member 13 to pass through the raised portion 1151 adjacent to the second end 115B. After the weight member 13 passes through the boss portion 1151, the weight member 13 is affected by gravity, and the weight member 13 can be slid back to the mounting traverse portion 122A by the extension chute 122B, so that the weight member 13 is located at the first position of the slide rail 115. The two ends 115B, at this time, the stencil 12 is rotated relative to the plate body 11 to a forward orientation (i.e., the stencil 12 observed by the user at this time is in the correct text or pattern orientation, as shown in Fig. 4D-b).

On the other hand, when the plate body 11 is changed in angle from the position opposite to the position of FIG. 5A (ie, from the flat state to the upright state), in the case where the angle change is less than a predetermined angle (ie, the critical angle), the adjacent rails are adjacent. The raised portion 1151 of the second end 115B of the 115 can cause the decorative plate 12 to be in a non-positive orientation (ie, the decorative plate 12 observed by the user at this time is located in a skewed text or pattern orientation, as shown in FIG. 5B-a, FIG. 5B- b)), and the position of each member can refer to the foregoing content; until the plate body 11 continues to produce an angle change greater than a predetermined angle, the weight member 13 can slide along the sliding portion 115 across the boss portion 1151, thereby Driving the decorative plate 12 relative to the plate body 11 to rotate to a forward orientation (ie, the decorative plate 12 observed by the user at this time is in the correct text or pattern orientation, as shown in FIG. 5C-a, FIG. 5C-b); Until the plate body 11 reaches the end point of the angular change, the weight member 13 can be slid back to the mounting traverse portion 122A by the extension chute 122B, so that the weight member 13 is located at the first end 115A of the slide rail 115, and the stencil 12 is opposite to the plate The body 11 is rotated to a forward orientation (as shown in Figures 5D-a, 5D-b).

It should be noted that, in the present embodiment, the aforementioned predetermined angle is about 45°, in other words, the plate body 11 of the embodiment needs to be rotated more than 45°, and the stencil 12 starts to rotate. In a variant embodiment, the protrusions 1151 adjacent to the first end 115A and the second end 115B of the slide rail 115 may have different protrusion heights, and the two extension slots 12 2B also have different extension lengths. Therefore, when the plate body 11 produces an angle change in different directions, the critical angle at which the decorative plate 12 starts to rotate is different (the height obstacle formed by the convex portion 1151 is different).

In another variant embodiment, the rail 115 may be provided with a raised portion 1151 only adjacent the first end 115A. When the plate body 11 produces an angular change, in the case where the angle change is less than a predetermined angle (ie, a critical angle), the raised portion 1151 adjacent to the first end 115A of the slide rail 115 may cause the decorative plate 12 to be in a non-positive orientation. (ie, the stencil 12 observed by the user at this time is located in a skewed text or pattern orientation); likewise, the weight member 13 can span the raised portion 1151 until the panel 11 continues to produce an angular change greater than a predetermined angle. And sliding along the slide rail 115, thereby rotating the stencil 12 relative to the plate body 11 to a forward orientation (ie, the stencil 12 observed by the user at this time is in the correct text or pattern orientation), at the same time, The weight member 13 can be slid back to the mounting traverse portion 122A by the extension chute 122B such that the weight member 13 is located at the second end 115B of the slide rail 115; this portion is identical to the foregoing description.

On the contrary, since the second end 115B adjacent to the sliding rail 115 has no design of the convex portion 1151, when the angle of the plate body 11 changes in the opposite direction, the weight member 13 can immediately produce the sliding effect along the sliding rail 115. Thereby, the decorative plate 12 is synchronously rotated relative to the plate body 11 to a forward orientation.

In addition, in the foregoing two embodiments, the extending chute 122B on both sides of the mounting traversing portion 122A can provide the effect of reducing the size of the sliding rail 115. As shown in FIG. 1A, FIG. 1B and FIG. 2B, the decorative version 121 is substantially The stencil accommodating portion 113 is a circular accommodating groove, and the decorative version 121 is configured by the pivot 123, the pivot member 124 and the pivot hole 1131 in the garnish receiving portion 113. The position of the extending slot 122B is closer to the pivoting center of the decorative version 121 (ie, the assembly of the pivot 123 and the pivot member 124) relative to the mounting traversing portion 122A, such as As shown in FIG. 2B, the distance between the mounting traverse portion 122A and the pivot center is L1, and the distance between the end of the extension chute 122B and the pivot center is L2, and L1 is greater than L2, so that the weight member 13 is slid by the mounting traverse portion 122A. After the extension chute 122B, the weight member 13 can have a smaller radius of rotation, so that the size of the rail 115 can be reduced. The stencil unit may further include a fixing member 125 connected to the pivoting member 124 and fixed to the rear surface 112 of the board body 11. For example, the fixing member 125 may be a screw (ie, the aforementioned pivot member 124). The fixing is applied to the decorative body 121, and the use of the fixing member 125 can avoid the assembly problem that the aforementioned screw completely locks the decorative body 121 and causes the decorative version 121 to be unable to rotate.

On the other hand, the range in which the slide rail 115 of the present invention extends is related to the angle between the bottom edge and the side edge of the plate body 11, since the plate body 11 is tilted from the bottom edge to the support surface with the side edge as the support surface. For example, the angle between the bottom edge and the side edge of the plate body 11 of the present embodiment is substantially about 90 degrees, so that the weight portion 13 can drive the decorative version body 121 to pivot the same angular range, the slide rail 115 is along the edge. The outer edge of the circular garnish receiving portion 113 extends about a quarter of a circumference, and since the through groove 114 defines the range in which the mounting portion 122 rotates, it is formed outside the circular garnish receiving portion 113. The edge slot 114 also extends approximately one quarter of a perimeter angle corresponding to the rail 115. In another variation, if the angle between the bottom edge of the plate body 11 and the side edge is 60 degrees, the slide rail 115 can extend about one third of the circumference along the outer edge of the garnish receiving portion 113. Similarly, the slot 114 also extends approximately one-third of the circumference of the rail 115; in other words, the present invention can be applied to a variety of different profiles.

Furthermore, the weight member 13 can be composed of a weight member 131 and a bolt member 132. The bolt member 132 includes a bolt head portion 1321, a bolt connecting portion 1322 and a connecting cylinder 1332. The bolt connecting portion 1322 is a bolt connecting portion 1322. The mounting portion 122A is connected to the weight portion 131, and the bolt head 1321 can be abutted against the aforementioned sliding rail 115; therefore, when the weight member 13 starts to move, the matching portion 1151 is matched. The reaction force of the weight member 13 is such that the connecting cylinder 1323 can be first slid by the mounting traverse portion 122A to the extending chute 122B, and then the cooperation of the bolt head portion 1321 and the sliding rail 115 causes the weight member 13 to move. Version body 121.

In a broader sense, the stencil unit of the present invention can be simplified into the cooperation of the plate body 11, the stencil 12, the weight member 13 and the slide rail 115, and the above-mentioned effects can be achieved. The plate body 11 is provided with a slide rail 115 and a pivoting stencil 12 having a decorative version 121 and a mounting portion 122 extending from the decorative version 121, the mounting portion having a mounting traversing portion 122A and obliquely facing away from the mounting traversing portion 122A The extended sliding chute 122B has a design of the raised portion 1151 on the sliding rail 115, and the weight member is disposed on the mounting traverse portion 122A and abuts against the sliding rail 115. Therefore, when the angle of the plate body 11 is changed, in the case where the angle change is less than a predetermined angle (ie, a critical angle), the convex portion 1151 can support the weight member 13 to place the decorative plate 12 in a non-forward orientation (ie, use The stencil 12 observed at this time is located in a skewed text or pattern orientation; until the slab 11 continues to produce an angular change greater than a predetermined angle, the weight member 13 can span the raised portion 1151 and along the slide rail 115. Sliding, thereby driving the stencil 12 to rotate to a positive orientation relative to the panel 11 (ie, the stencil 12 observed by the user at this time is in the correct text or pattern orientation).

In addition, the stencil unit of the present invention is more applicable to a casing of an electronic product, such as a computer casing, a server casing, etc., as shown in FIG. 6, the casing may include a casing body 10 and is mounted on the casing. The decorative plate 12, the weight member 13 and the sliding rail 115 on the main body 10, wherein the sliding rail 115 is disposed on the casing body, and the decorative plate 12 is pivotally disposed on the casing body and corresponds to the sliding rail 115, and the weighting member The 13 series is assembled to the stencil 12 and abuts against the sliding rail 115. Specifically, the casing body 10 can have at least one front plate body 11A, for example, a front plate body 11A, a side plate body, an upper plate body, and a lower plate body. And the rear plate body and the like, and the front plate body 11A is equivalent to the above-mentioned plate body 11, in other words, the front plate body 11A is also provided with a plate receiving portion 113 and a corresponding plate receiving portion. The groove 121 of the 113 is disposed, and the decorative body 121 of the decorative plate 12 is pivoted in the decorative plate receiving portion 113, and the mounting portion 122 of the decorative plate 12 is disposed through the through groove 114 and located behind the front plate body 11. Board surface. When the user flips the casing, the aforementioned effect can be produced: the angle of the casing changes more than a critical angle, and the orientation of the decorative plate begins to rotate to a forward orientation.
