In the figure, the unit structure according to the present embodiment is used as a display device, and mainly includes a plurality of units 10, a plurality of vertical shafts 15, and a plurality of horizontal shafts 16. .

  FIG. 2 is a perspective view showing units constituting the unit structure. In the figure, a unit 10 is a display unit configured by assembling four rectangular panels 11 containing a plurality of LEDs and a control circuit (both not shown) for controlling the lighting of each LED. It is a size that can be handled easily. Moreover, it has a drip-proof structure so that it can be used outdoors.

  FIG. 3 is a perspective view of the unit 10 as seen from the back side. Two positioning pins 12 for attaching the unit 10 to the frame-side frame 20 shown in FIG. 7 are provided on the back surface of the unit 10. The two positioning pins 12 are provided at two corners opposed to each other in the diagonal direction among the four corners of the unit 10. Although it may be provided at the remaining two corners, two are sufficient for positioning. As shown in FIG. 7, the positioning of the unit 10 can be temporarily installed by inserting the two positioning pins 12 of the unit 10 into the holes 21 formed in the frame 20. Moreover, it can remove by pulling out in the front direction (arrow A direction of FIG. 7).

  Returning to FIG. 3, a vertical hook hanging tool 13 and a horizontal hook hanging tool 14 each formed in a U-shape are provided at 90 ° different positions in the central portion on the back of the unit 10. The tools 13 and 14 are for fixing so that they are not detached from the frame 20 after being attached to the frame 20 by the positioning pins 12 of the unit 10. Since each unit 10 is fixed to the frame 20 with the vertical hook hook 13 and the horizontal hook hook 14, high safety can be obtained.

  As shown in FIG. 1, each unit 10 is attached to a vertical shaft 15 and a horizontal shaft 16. The vertical shaft 15 and the horizontal shaft 16 are provided in a number corresponding to the number of units 10 to be used, and are arranged in a lattice shape and rotatable with respect to the frame 20 (see FIG. 7). The vertical shaft 15 is provided with a plurality of vertical hooks 17 that are engaged with the vertical hook hooks 13 of the unit 10 at regular intervals (that is, when the plurality of units 10 are stacked, the vertical hook hooks of the units 10 are overlapped). A vertical hook 17 is provided at the position where the tool 13 comes). The horizontal shaft 16 is provided with a plurality of horizontal hooks 18 that are engaged with the horizontal hook hooks 14 of the unit 10 at regular intervals (that is, when the plurality of units 10 are stacked, the horizontal hook hooks of the units 10 are overlapped). A lateral hook 18 is provided at a position where the tool 14 comes).

  In addition, the unit 10 is provided with a connector (not shown) that can perform signal communication with the adjacent units 10 when a plurality of the units 10 are installed.

  As shown in FIG. 4, the vertical hook 17 can be engaged with the vertical hook hook 13 of the unit 10 by rotating the vertical shaft 15 in the arrow B direction. That is, when the unit 10 is attached to the vertical shaft 15, the vertical shaft 15 is rotated in the arrow B direction. Further, when the unit 10 is removed from the vertical shaft 15, the vertical shaft 15 is rotated in the direction B 'opposite to the arrow B direction.

  Needless to say, since the vertical shaft 15 is provided with a plurality of vertical hooks 17, rotating the vertical shaft 15 in the direction of arrow B causes all the vertical hooks 17 of the vertical shaft 15 to move in the vertical direction. The unit 10 can be engaged with the vertical hook 13. Further, by rotating the vertical shaft 15 in the direction of the arrow B ′, each vertical hook 17 of the vertical shaft 15 can be detached from the vertical hook hooks 13 of all the units 10 in the column. The rotation of the vertical shaft 15 may be performed electrically or manually.

  Further, the vertical shaft 15 may be slid up and down as shown in FIG. 5 instead of rotating. In this case, it is necessary to change the orientation of the vertical hook 13 of the unit 10 by 90 degrees. By sliding the vertical shaft 15 downward, the vertical hook 17 of the vertical shaft 15 engages with the vertical hook hook 13 of the unit 10 and disengages by sliding upward.

  Further, as shown in FIG. 6, the vertical hook 17 of the vertical shaft 15 is rotatable with respect to the vertical shaft 15 and is opposed to the vertical hook hanging tool 13 of the unit 10 (that is, a position indicated by an arrow E). And may be urged by an elastic member such as a spring toward the stop position (or vice versa, the elastic member such as a spring is pulled toward the stop position). By doing in this way, when the vertical hook hook 13 of the unit 10 is pushed in, the vertical hook 17 moves in the direction of escaping from the vertical hook hook 13 (direction indicated by arrow D). When the flange portion 17 </ b> A gets over the vertical hook hook 13, the vertical hook 17 returns to the stop position (position indicated by arrow E) and engages with the vertical hook hook 13.

  When the vertical hook 17 of the vertical shaft 15 is removed from the vertical hook hook 13 of the unit 10, the vertical shaft 15 itself may be rotated in the direction of the arrow B '. At this time, since the vertical hook 17 rotates integrally with the vertical shaft 15, it is detached from the vertical hook hook 13 of the unit 10. Thus, the vertical hook 17 of the vertical shaft 15 can be automatically engaged with the vertical hook hook 13 of the unit 10. A mechanism (illustrated) that supports the vertical hook 17 so as to be rotatable with respect to the vertical shaft 15 and an elastic member that pulls the vertical hook 17 in the direction of the stop position of the vertical hook 17 constitute a lock mechanism. Incidentally, this locking mechanism can also be applied to a sliding type. That is, the elastic member is provided so that the vertical hook 17 of the vertical shaft 15 is urged in the direction in which the vertical hook 17 of the unit 10 is engaged with the vertical hook hook 13.

  The horizontal shaft 16 has substantially the same structure as the vertical shaft 15, and the horizontal hook 18 is engaged with the horizontal hook hook 14 of the unit 10 by rotating the horizontal shaft 16 in the direction of arrow C as shown in FIG. Can be combined. That is, when the unit 10 is attached to the horizontal shaft 16, the horizontal shaft 16 is rotated in the direction of arrow C. When removing the unit 10 from the horizontal shaft 16, the horizontal shaft 16 is rotated in the direction of the arrow C 'opposite to the direction of the arrow C.

  Since the horizontal shaft 16 is provided with a plurality of horizontal hooks 18 in the same manner as the vertical shaft 15, each horizontal hook of the horizontal shaft 16 is rotated by rotating the horizontal shaft 16 in the direction of arrow C. 18 can be engaged with the horizontal hook 14 of all units 10 in the row. Further, by rotating the horizontal shaft 16 in the direction of the arrow C ′ opposite to the arrow C, the horizontal hooks 18 of the horizontal shaft 16 can be detached from the horizontal hook hooks 14 of all the units 10 in the row. The rotation of the horizontal shaft 16 may be performed electrically or manually.

  Further, the horizontal shaft 16 may be slid left and right instead of rotating. In this case, it is necessary to change the direction of the horizontal hook 14 of the unit 10 by 90 degrees. For example, when the horizontal shaft 16 is slid to the left, the horizontal hook 18 of the horizontal shaft 16 is engaged with the horizontal hook hook 14 of the unit 10 and is released by being slid right.

  Similarly to the vertical shaft 15, the horizontal shaft 16 also allows the horizontal hook 18 of the horizontal shaft 16 to be rotatable with respect to the horizontal shaft 16, and the position facing the horizontal hook hook 14 of the unit 10 (see FIG. 6). Then, it is regulated to stop at the position indicated by the arrow E, and is further urged by an elastic member such as a spring in the direction of the stop position (or vice versa, the elastic member such as a spring is pulled toward the stop position). Anyway. By doing in this way, when the horizontal hook hanging tool 14 of the unit 10 is pushed in, the horizontal hook 18 moves in a direction of escaping from the horizontal hook hanging tool 14 (direction shown by an arrow D with reference to FIG. 6). Thereafter, the hook portion of the horizontal hook 18 (corresponding to the hook portion 17A of the vertical hook 17) gets over the horizontal hook hanging tool 14, so that the horizontal hook 18 is in the stop position (the position indicated by the arrow E with the aid of FIG. 6). Return and engage the side hook 14.

  When the lateral hook 18 of the lateral shaft 16 is removed from the lateral hook hook 14 of the unit 10, the lateral shaft 16 itself may be rotated in the reverse direction (C ′ direction in FIG. 1). At this time, the horizontal hook 18 rotates integrally with the horizontal shaft 16, so that it is detached from the horizontal hook hook 14 of the unit 10. In this way, the lateral hook 18 of the lateral shaft 16 can be automatically engaged with the lateral hook hook 14 of the unit 10. A mechanism (not shown) that supports the horizontal hook 18 rotatably with respect to the horizontal shaft 16 and an elastic member that pulls the horizontal hook 18 in the direction of the stop position of the horizontal hook 18 constitute a lock mechanism. Incidentally, this locking mechanism can also be applied to a sliding type. That is, the elastic member is provided so that the lateral hook 18 of the lateral shaft 16 is biased in the direction in which the lateral hook 18 of the unit 10 is engaged.

  FIG. 7 is a view showing a state in which the vertical shaft 15, the horizontal shaft 16, and the unit 10 are assembled to the frame 20. By configuring the frame 20 as a pedestal role when the display device is attached to a wall surface or a column, positioning of the unit 10, and holders of the vertical and horizontal shafts 15 and 16, the installation work can be made more efficient. By providing the frame 20 with a lock mechanism for the rotation and sliding of the vertical and horizontal shafts 15 and 16, the vertical and horizontal shafts 15 and 16 can be prevented from rotating or sliding freely due to vibration or the like. Further improvement can be achieved.

  Thus, according to the unit structure of the present embodiment, the unit 10 having the vertical hook hook 13 and the horizontal hook hook 14 and the vertical hook 17 having the vertical hook 17 engaged with the vertical hook hook 13 of the unit 10 are provided. Fixing and fixing the unit 10 by having a shaft 15 and a horizontal shaft 16 having a horizontal hook 18 engaged with the horizontal hook hanging tool 14 of the unit 10, and rotating or sliding the vertical shaft 15 and the horizontal shaft 16. Since the structure can be released, a plurality of units 10 are prepared, and a plurality of vertical shafts 15 and a plurality of horizontal shafts 16 are prepared and arranged in a grid, so that only the unit 10 at the vertical and horizontal intersections is fixed or fixed. Or cancel it. As a result, the unit 10 requiring maintenance can be easily removed, and maintenance can be performed in a safe place. Also, the defective unit 10 can be easily replaced. Also, the initial installation can be performed simply by inserting the unit 10 into the frame 20 and hooking it, so that the work efficiency can be improved. In addition, the size of the display device can be easily changed simply by changing the quantity of the units 10, and standardization can be achieved.

  In addition, in the said embodiment, when the vertical and horizontal shafts 15 and 16 are too long, you may divide | segment into several and rotate or slide in each. For example, in the case of dividing into two, it may be divided into two vertically in the vicinity of the center and rotated or slid on each of the upper side and the lower side.

  The present invention has an effect that installation and maintenance can be performed safely and easily, and can be applied to a display device or the like.
