Note that a pair of receiving portions 5 are provided on the wall surface 3, for example, depending on the size of the display board to be attached.

  The display board 7 displays various information on the surface. Various display contents such as characters and figures can be applied as display contents on the display board, but the illustration is omitted. The shape of the display board 7 is not limited to the illustrated example, and various shapes such as a circle, a square, and other polygons can be applied. Marks 13 are formed at predetermined positions on the upper and lower surfaces of the display panel 7. The mark 13 is formed in a convex shape so as to be visible from the front surface of the display board, for example.

  As shown in FIG. 1B, a claw portion 15 and an engagement protrusion 17 are formed on the back surface of the display plate 7. The engagement protrusion 17 is a protrusion that is inserted into the fixing hole 9 of the receiving portion 5.

  A pair of claw portions 15 are formed on both sides of the engaging protrusion 17. The claw portion 15 can lock the holding collar portion 11 of the receiving portion 5. The claw portions 15 are respectively formed on the upper and lower sides of the display plate 7 and are locked so as to sandwich the holding collar portion 11 from both sides of the receiving portion 5. That is, in the example of FIG. 1, the claw portions 15 are formed in pairs (on both sides) on the upper and lower sides of the receiving portions 5 (two on the upper and lower sides), respectively, on the two receiving portions 5. A total of eight are formed. In addition, although mentioned later for details, the mark 13 is provided in the site | part substantially corresponding to the formation position of the nail | claw part 15. FIG.

  FIG. 2 is an enlarged view of a portion A in FIG. A groove 16 that can be fitted to the holding hook 11 is formed at the tip of the claw 15 (on the holding hook 11 side). The grooves 16 are formed in the vertical direction of the display panel. As the groove 16 is fitted to the holding hook 11, the claw 15 and the holding hook 11 are locked. That is, the display board 7 is fixed to the receiving portion 5. Therefore, when the display board 7 is viewed from the front, the movement in the vertical and horizontal directions is restricted by the engagement with the engagement protrusion 17 and the fixing hole 9, and further, the holding hook 11 is locked by the claw 15. , Forward movement is restricted. For this reason, the display board 7 is reliably fixed to the receiving part 5 (wall surface 3).

  FIG. 3A is a diagram showing the back surface of the display board 7. A pair of engaging protrusions 17 are formed on the upper and lower sides of the display plate 7 at positions corresponding to the fixing holes 9 of the receiving portion 5. Further, a pair is formed on the left and right at positions corresponding to the pair of receiving portions 5. Further, as described above, the claw portions 15 are formed on both sides of each engagement protrusion 17.

  FIG. 3B is an enlarged view of a portion B of FIG. 3A and shows the vicinity of the claw portion 15. On the front surface of the claw portion 15 (the back surface side of the display plate 7), a claw portion-side fitting portion 21 is formed. The nail | claw part side fitting part 21 is a site | part which can be fitted with the jig mentioned later, for example, is a recessed part.

As described above, the groove 16 is formed at the tip of the claw portion 15. A protrusion 25 is formed at the lower part of the claw part 15 (display panel main body side). The protrusion 25 is fitted into a guide 23 formed on the back surface of the display panel 7. At the tip of the protrusion 25, a claw for preventing the drop from the guide 23 is formed. That is, the claw portion 15 is movable along the guide 23.

  Moreover, the nail | claw part 15 is moved back (on the opposite side to the receiving part 5) normally (this state is called a lock release state). In this state, the claw portion 15 is not locked with the holding collar portion 11. In this state, the groove 16 is positioned at substantially the same height as the holding collar 11.

  FIG.3 (c) is a figure which shows the state which moved the nail | claw part 15 to the front (receiving part 5 side). That is, since the protrusion 25 fits into the guide 23, the claw portion 15 is movable along the guide 23 (in the direction of arrow F in the figure). Therefore, the claw portion 15 can move straight in the receiving portion direction.

  FIG.4 (c) is the EE sectional view taken on the line of FIG.3 (c). As shown in FIG. 4C, when the claw portion 15 is moved forward (on the receiving portion 5 side and in the direction of arrow F in the figure) along the guide 23, the groove 16 of the claw portion 15 is straightened. Fit into the holding collar 11. Therefore, the holding hook 11 (receiving portion 5) can be locked by the claw portion 15 (this state is referred to as a locked state).

  Next, a method for fixing the display board 7 will be described. First, the receiving portion 5 is installed at a desired position on the wall surface 3. 5A and 5B are diagrams showing a state in which the receiving portion 5 is attached to the wall surface 3, FIG. 5A is a front view, FIG. 5B is a plan view, and FIG. 6 is GG in FIG. It is line sectional drawing. The receiving portion 5 is installed at a site corresponding to the position of the engagement protrusion 17 or the like of the display board 7. The receiving part 5 is fixed so that the holding hook part 11 is on the front side.

  As described above, a plurality of fixing holes 9 are formed on the front surface of the receiving portion 5. In the present embodiment, an example in which two upper and lower fixing holes 9 are used will be described. However, the fixing hole 9 to be used is appropriately determined according to the size of the display board 7 and the like.

  As shown in FIG. 6, the receiving portion 5 is fixed to the wall surface 3 by screws 19. The screw 19 is attached from the front of the receiving portion 5 through the fixing hole 9. The receiving part 5 has a thickness at which at least the engaging protrusion 17 can be inserted, and a space is formed so as not to interfere with the engaging protrusion 17.

  Next, as shown in FIG. 7, the display plate 7 is attached to the receiving portion 5. FIG. 7A is a perspective view of the display plate 7 with respect to a front view showing a state where the display plate 7 is attached, and FIG. 7B is a plan view. FIG. 8 is a cross-sectional view taken along the line HH in the vicinity of the portion I in FIG. As shown to Fig.7 (a), the display board 7 is higher than the full height of the receiving part 5, and if the display board 7 is attached, the receiving part 5 cannot be visually recognized from the display board front side.

  As shown in FIG. 8, by inserting the engagement protrusion 17 of the display plate 7 into the fixing hole 9 of the receiving portion 5, the display plate 7 is attached to the receiving portion 9 and temporarily fixed. At this time, each claw portion 15 of the display board 7 is in an unlocked state (all moved rearward (in a direction opposite to the claw portion 15 and away from the receiving portion 5)). That is, the claw portion 15 does not interfere with the receiving portion 5. By pulling the display plate 7 forward, the engagement protrusion 17 can be removed from the fixing hole 9 and removed from the receiving portion 5.

  A mark 13 is provided at a position corresponding to the part of the claw part side fitting part 21 of the claw part 15. That is, the position of the claw portion side fitting portion 21 on the back surface side of the display plate 7 can be recognized from the upper and lower surfaces of the display plate (front if the mark is a protrusion).

  Next, the display board 7 is fixed to the receiving part 5. A fixing jig 27 is used for fixing. FIG. 9 is a view showing the fixing jig 27, FIG. 9 (a) is a perspective view, and FIG. 9 (b) is a side view. The fixing jig 27 is a substantially L-shaped member. The fixing jig 27 is formed with an insertion portion 27b substantially perpendicular to the handle portion 27a. A jig side fitting portion 29 is provided at the tip of the insertion portion 27b. The jig-side fitting portion 29 is a portion that can be fitted with the above-described claw-side fitting portion 21 and is, for example, a protrusion having a substantially circular cross-sectional shape. The jig side fitting portion 29 is formed on the lower surface of the insertion portion 27b (in the same direction as the handle portion 27a).

  FIG. 10A is a rear view of a state in which the display plate 7 is attached to the receiving portion 5 (a wall surface perspective view seen from the wall surface side). In addition, about the receiving part 5, only arrangement | positioning is shown with a dotted line. First, as shown in FIG. 10A, the insertion portion 27b of the fixing jig 27 is inserted into the position of the claw portion 15 on the upper side of the display plate 7 from the upper surface side of the display plate 7 (in the direction of arrow J in the figure). . Although the figure shows a case where there is a sufficient space above the display panel, the insertion portion 27b of the fixing jig 27 can be inserted into the back surface of the display panel even when a plurality of display panels are installed vertically. If there is a gap, the following operation can be performed.

  FIG. 10B is a plan view of the vicinity of the insertion site of the fixing jig 27. In a state where the display plate 7 is attached to the receiving portion 5 (temporarily fixed), a gap 31 corresponding to the thickness of the receiving portion 5 is formed between the back surface of the display plate 7 and the wall surface 3. Further, as described above, the mark 13 is formed on the upper surface of the display plate 7 at a position corresponding to the claw portion side fitting portion 21 of the claw portion 15. Therefore, by fitting the fixing jig 27 into the gap 31 with the position of the jig side fitting part 29 of the fixing jig 27 aligned with the position of the mark 13, the jig side fitting part 29 and the claw part side fitting are inserted. The position of the part 21 can be adjusted.

  The handle portion 27b is preferably longer than the thickness of the target display plate (the thickness of the display plate at the use position of the fixing jig). In this way, the fixing jig 27 can be used from the front side of the display board 7. Moreover, the length of the insertion part 27b should just be more than the length from the upper surface (or lower surface) of the display board 7 to the nail | claw part 15 (claw part side protrusion part). However, if the length of the insertion portion 27b is too long, the insertion property is deteriorated. Therefore, when the handle portion 27a is brought into contact with the upper surface (or the lower surface) of the display plate 7, the position of the jig side fitting portion 27b is determined. May be of a length that substantially matches the claw portion-side fitting portion 21.

  Next, as shown in FIGS. 11A and 11B, the fixing jig 27 is moved in the forward direction (front of the display plate), and the jig-side fitting portion 29 of the fixing jig 27 is moved to the claw portion. The side fitting part 21 is fitted. In addition, the shape of the nail | claw part side fitting part 21 and the jig | tool side fitting part 29 is not restricted to circular as shown in figure, Various forms, such as a polygon, may be sufficient. In this case, by matching each other's shape, if a fixing jig having a jig side fitting portion that matches the shape of the claw portion side fitting portion is not used, the fitting portions can be fitted together. Can not.

  Next, as shown in FIGS. 11A and 11B, the fixing jig 27 fitted to the claw portion 15 is moved to the receiving portion 5 side (in the direction of arrow K in the figure). That is, the fixing jig 27 is moved along the edge of the display board 7 with the fixing jig inserted. When the claw portion 15 moves toward the receiving portion 5, the claw portion 15 (groove 16) is fitted into the holding collar portion 11. That is, the holding hook part 11 is locked by the claw part 15 (becomes locked).

  In this state, by removing the fixing jig 27 from the claw part 15, the holding hook part 11 is locked by the claw part 15. The above operation is performed on each claw part 15, each claw part 15 is moved to the holding hook part 11 side, and the display plate 7 is fixed to the receiving part 5 by the claw part 15 and the holding hook part 11. The operation of the lower claw portion 15 may be performed by inserting the fixing jig 27 from the lower surface side.

  Moreover, what is necessary is just to perform the above-mentioned process reversely, when removing the display board 7. FIG.

  According to the present invention, the display plate 7 can be reliably fixed. In particular, the locking projection 17 can temporarily fix the display panel and prevent the display panel from being displaced. Further, the display plate 7 is securely fixed by the locking of the claw portion 15 and the holding hook portion 11. For this reason, there is no fear of dropping off the display board.

  Further, since the display plate 7 is fixed to the receiving portion 5 by sliding movement of the claw portion 15, the display plate 7 can be easily attached and detached. Further, since the slide movement of the claw portion 15 is performed by a special fixing jig 27, only a specific operator having the fixing jig 27 can perform the attaching / detaching operation of the display plate 7. In addition, by changing the shape of the claw portion side fitting portion 21 by the display plate, it is not possible to perform the detachment work unless the person has a fixing jig that matches the display plate. can do.

  Further, since the fixing structure such as the claw portion 15 is on the back surface side of the display plate 7, it cannot be visually recognized from the front surface of the display plate and is excellent in appearance. In addition, since the operation of the claw portion 15 can be performed from the front side of the display board 7, a work space for attaching and detaching the display board around the display board 7 is unnecessary. For this reason, even when a plurality of display panels 7 are provided, extremely high installation efficiency can be obtained.

  Moreover, since the nail | claw part 15 moves along the guide 23 of the display board 7, the nail | claw part 15 moves straight to the holding hook part 11 side. For this reason, the holding hook 11 can be reliably locked. Further, since the protrusion 25 is fitted in the guide 23, the claw portion 15 is not likely to fall off the display board 7.

  Moreover, since the position of the nail | claw part 15 (claw part side fitting part 21) can be recognized from the front surface of a display board by the mark 13, it is easy to grasp | ascertain the insertion position of the fixing jig 27. FIG. For this reason, it is excellent in the work of attaching and detaching the display panel.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, the mark 13 is provided at a portion corresponding to the position of the claw portion side fitting portion 21 at the position where the lock of the claw portion 15 is released, but the claw portion side fitting portion 21 in a state where the claw portion 15 is locked. It may be provided in a part corresponding to the position of the two, or both of them may be provided. By grasping the position in the locked state, it becomes easy to grasp the fixing jig insertion position when removing the display board. Moreover, by providing both, the locked state and the unlocked state can be grasped. That is, by inserting the fixing jig 27, fitting the jig side fitting part 29 to the claw part side fitting part 21, and grasping the position of the fixing jig, the state of the claw part 15 can be determined. It can be easily grasped, and forgetting to lock the claw portion 15 can be prevented.

  Moreover, the structure of the receiving part 5 and the display board 7 is rotated 90 degree | times, and it is good also considering the sliding direction of the nail | claw part 15 as a vertical direction instead of a horizontal direction. Even in this case, the holding hook portion 11 can be locked by the claw portion 15. In this case, the fixing jig 27 may be inserted from the side of the display plate 7.
