Here, the positional relationship of each part which comprises the attachment apparatus 3 is demonstrated.

As shown in FIG. 11, the mounting portion 72 is located above the fitting receiving portion 71, and the blocking portion 78 is provided so as to block a part of the insertion space 75 of the fitting receiving portion 71. Yes.
As shown in FIG. 3, the ball portion 66 is stored in the storage space 73 of the ball receiving portion 70.

The ball portion 66 serving as the rotation center of the attachment-side fitting portion 56 is located inside the light-emitting panel 2 when viewed in plan and within a range of 1/3 of the light-emitting panel 2 from the end of the light-emitting panel 2. ing. The ball portion 66 serving as the rotation center of the attachment-side fitting portion 56 is preferably located in the vicinity of the end portion of the light emitting panel 2.

  Then, the positional relationship at the time of attaching / detaching the light emission panel 2 to the attachment apparatus 3 using the light emission panel attachment structure 1 is demonstrated.

First, the positional relationship when the light emitting panel 2 is attached to the attachment device 3 will be described.
The panel side fitting portion 11 is slid and fitted to the attachment side fitting portion 56. That is, the light emitting panel 2 is attached by being slid in a direction parallel to the light emitting surface 8 of the light emitting panel 2 (a fitting direction).
Specifically, the power supply fitting pieces 25 and 26 of the panel side fitting portion 11 are inserted into the insertion space 75 of the fitting receiving portion 71 of the attachment side fitting portion 56, and the power supply fitting piece 26 and the signal are inserted. A side wall portion 107 forming a side surface of the fitting receiving portion 71 is interposed between the fixing piece 27 for use.
At this time, the panel-side power supply terminals 32 and 33 are slid and attached to the base conductive portions 90 and 91. That is, the panel-side power supply terminals 32 and 33 are slid and attached while being in contact with the base conductive portions 90 and 91. Therefore, the panel-side power supply terminals 32 and 33 can be sufficiently brought into contact with the base conductive portions 90 and 91, and sufficient conduction can be obtained.
The signal conductive portion 35 of the signal fixing piece 27 is electrically connected to a part of the mounting circuit of the mounting portion 72.

The operation at this time will be described by paying attention to the inside of the fitting receiving portion 71. When the feeding fitting pieces 25 and 26 are inserted into the insertion space 75 as shown in FIG. The inclined surface 39 comes into contact with the first bent portion 105. Further, when the power supply fitting pieces 25 and 26 are inserted, the first bent portion 105 is elastically deformed in a direction away from the inclined surface 39 while sliding along the inclined surface 39. When the inclined surface 39 comes into contact with the engaging surface 101, the first bent portion 105 is moved from the locking piece 37 of the power feeding fitting piece 26 into the notch 38 for fixing as shown in FIG. Inserted into.
Then, after the power supply fitting pieces 25 and 26 have been pushed all the way, when the power supply fitting pieces 25 and 26 are released, the drive portion 115 of the guide rod 99 is locked through the row-side path. Locked in a groove (not shown). Further, the slide member 96 is biased by the compression coil spring 98, and the power supply fitting pieces 25 and 26 are locked in the insertion space 75.
At this time, since the first bent portion 105 at the distal end portion of the protruding piece 102 is elastically locked in the fixing cutout portion 38, the power supply fitting pieces 25 and 26 cannot be removed.

  Then, the positional relationship at the time of removing the light emission panel 2 from the attachment apparatus 3 is demonstrated.

The panel side fitting portion 11 is slid in the fitting direction with respect to the attachment side fitting portion 56 and then pulled out. That is, after sliding once in the fitting direction that is parallel to the light emitting surface 8, it is slid in the opposite direction to the fitting direction and removed.
Specifically, in the state where the power supply fitting pieces 25 and 26 of the panel side fitting portion 11 are inserted into the insertion space 75 of the fitting receiving portion 71 of the attachment side fitting portion 56, in the insertion direction. The power supply fitting pieces 25, 26 of the panel side fitting portion 11 are slid, and then the light emitting panel 2 is pulled out from the mounting device 3 by applying an external force.
At this time, the panel-side power supply terminals 32 and 33 are slid on the panel-side power supply portions 86 and 87 and removed. That is, the panel side power supply terminals 32 and 33 are moved and removed while being in contact with the panel side power supply portions 86 and 87.
At this time, the fitting state of the panel side fitting portion 11 and the attachment side fitting portion 56 is released, and the light emitting panel 2 is separated from the attachment device 3.

The operation at this time will be described by paying attention to the inside of the fitting receiving portion 71. When the feeding fitting pieces 25 and 26 are pressed again as shown in FIG. It is released from the locking groove (not shown) and moves to the return path. As shown in FIG. 13B, the slide member 96 is urged by the compression coil spring 98 to move the power supply fitting pieces 25 and 26 to the opening side of the insertion space 75.
When the drive unit 115 of the guide rod 99 returns relatively to the starting point of the heart-shaped cam groove 100, the slide member 96 stops. Then, by pulling out the power supply fitting pieces 25 and 26 as shown in FIG. 13C, the power supply fitting pieces 25 and 26 are detached from the insertion space 75 of the fitting receiving portion 71.

  In this manner, the power feeding fitting pieces 25 and 26 are locked by being pushed into the insertion space 75 by the ejection mechanism 76 of the fitting receiving portion 71, and the power feeding fitting pieces 25 and 26 are pushed again to be locked. Is released, and the power supply fitting pieces 25 and 26 can be discharged from the insertion space 75.

  Next, an operation when changing the posture of the light emitting panel 2 in order to replace the light emitting panel 2 will be described. First, for convenience of explanation, the attachment device 3 will be described from a state of taking a parallel posture.

1, the light emitting panel mounting structure 1 and the other light emitting panel mounting structure 1 are distributed in a planar shape on the installation surface 4 to form a light emitting panel side-by-side structure 9 together with the other light emitting panel mounting structure 1. . The light emitting panel 2 is flush with the other light emitting panels 2 and forms one plane. The panel side fitting portion 11 of the light emitting panel 2 and the attachment side fitting portion 56 of the attachment device 3 are fitted to each other as shown in FIG. Are parallel.
The mounting device 3 has an obtuse angle between the shaft portion 65 and the fitting receiving portion 71 in a parallel posture. The stretchable portion 58 is in a contracted state, and the light emitting panel 2 and the installation surface 4 are in close proximity. Moreover, the attachment side fixing | fixed part 52 and 53 are mounted | worn with the fixing holes 45 and 46, and the attachment side fixing | fixed part 52 and 53 is in the state extended a little rather than natural length.

Subsequently, the light emitting panel 2 is rotated to bring the mounting device 3 into the crossing posture.
At this time, as shown in FIG. 14B, the attachment-side fitting portion 56 is orthogonal to the installation surface 4 with the connecting portion 60 positioned closer to the installation surface 4 than the attachment-side fitting portion 56 as a starting point. Rotate on the plane to be crossed.

At this time, as shown in FIG. 14B, the light emitting panel 2 is tilted in a direction intersecting with the installation surface 4, and the insertion opening of the fitting receiving portion 71 from the gap with the installation surface 4. 74 is visible.
Specifically, the angle β formed by the base portion 50 fixed to the installation surface 4 and the extended surface of the light emitting surface 8 of the light emitting panel 2 is 15 degrees or more and 90 degrees or less.
If it is this range, at the time of replacement | exchange, the insertion opening 74 of the fitting receiving part 71 will open widely, and it will become possible to insert the fitting pieces 25 and 26 for electric power feeding easily.
Further, at this time, the attachment-side fixing portions 52 and 53 are in an extended state as compared with the parallel posture as the light-emitting panel 2 is tilted, and the urging force toward the installation surface 4 is working.
Therefore, even if the light emission panel 2 cancels | releases the fitting state of the panel side fitting part 11 and the attachment side fitting part 56, it does not fall.

When the light emitting panel 2 is replaced with a new light emitting panel 2, the light emitting panel 2 is removed and the new light emitting panel 2 is attached in this crossing posture.
That is, the panel-side fitting portion 11 is pulled out from the attachment-side fitting portion 56 to release the fitting state, and the attachment-side fixing portions 52 and 53 are removed from the fixing holes 45 and 46 of the fixing pieces 42 and 43 of the light emitting panel 2. . Then, after attaching the attachment side fixing parts 52 and 53 to the fixing holes 45 and 46 of the fixing pieces 42 and 43 of the new light emitting panel 2, the panel side fitting part 11 and the attachment side fitting part 56 are fitted. A new light emitting panel 2 is attached to the attachment device 3.
And if needed, the light emission panel 2 is rotated and the attachment apparatus 3 is made into a parallel attitude | position.
At this time, since the light emitting panel 2 is urged toward the installation surface 4 by the restoring force of the attachment side fixing portions 52 and 53, it is possible to easily change from the intersecting posture to the parallel posture.

  By the way, in changing the mounting device 3 from the parallel posture to the crossing posture, when only the rotation operation of the mounting side fitting portion 56 with respect to the connecting portion 60 is performed, the position of the mounting side fitting portion 56 is in the vertical direction. Since the positions are substantially the same as in the parallel posture, the presence of the other light-emitting panels 2 may be spatially disturbed when the light-emitting panel 2 is replaced.

Therefore, in the light emitting panel mounting structure 1 of the present embodiment, the mounting device 3 includes the extendable portion 58 as described above. Therefore, the attachment device 3 can also move the attachment-side fitting portion 56 in the vertical direction in the crossing posture.
That is, as shown in FIG. 15A, the attachment device 3 takes a basic posture in which the extendable portion 58 takes a state similar to the parallel posture and an extended posture in which the extendable portion 58 extends in the intersecting posture. It is possible. That is, the basic posture is a posture that is taken when the light emitting panel 2 is changed in posture from the parallel posture only by the rotation operation, and the expansion / contraction part 58 is in a contracted state. That is, the position of the attachment-side fitting portion 56 is a posture in the vertical direction that is substantially the same as the parallel posture or slightly lower than the parallel posture.
As shown in FIG. 15B, the stretched posture is such that the stretchable portion 58 extends with respect to the basic posture, and the light emitting panel 2 is positioned below the basic posture.

  In other words, the position of the attachment side fitting portion 56 is lower than the lower surface of the other light emitting panel 2 that takes the parallel posture in the extended posture. In other words, the mounting side fitting portion 56 is disposed at a position that is separated in the vertical direction with respect to the installation surface 4 from the position of the mounting side fitting portion 56 when the mounting side fitting portion 56 is in the parallel posture. Therefore, when fitting the panel side fitting part 11 in the attachment side fitting part 56, it can fit in the position away with respect to the to-be-installed surface 4 rather than the other light emission panel 2, and the other light emission panel 2 can be fitted. It does not get in the way. Further, the attachment side fixing portions 52 and 53 are in an extended state in the extended posture as compared with the parallel posture, and a biasing force is acting in the contracting direction. Therefore, it is easy to return to a parallel posture after replacement.

Here, in the above description, the change from the parallel posture to the intersecting posture and the change from the basic posture to the extended posture have been described independently. Along with the operation, the center of gravity moves downward and switches from the basic posture to the extended posture.
That is, when the extension / contraction part 58 and the attachment side fixing parts 52 and 53 are in the basic posture against the restoring force of the extension / contraction part 58 and the attachment side fixing parts 52 and 53 due to the weight of the light emitting panel 2 or the external force of the user or the like. It grows in comparison. Therefore, the panel side fitting part 11 will be located below the lower surface of the other light emission panel which takes a parallel attitude | position.

As described above, since the fitting state of the panel-side fitting portion 11 and the attachment-side fitting portion 56 can be released below the other light-emitting panels 2, it is affected by the spatial influence of the other light-emitting panels. It is possible to replace without.
Therefore, it is not necessary to form a working gap for attaching the light emitting panel 2 between the light emitting panels 2 and 2, and the light emitting panel 2 can be disposed substantially without a gap with respect to the installation surface 4.

  According to the light emitting panel mounting structure 1 of the first embodiment, the power feeding fitting pieces 25 and 26 are inserted into the fitting receiving portion 71 and the power feeding fitting is performed on the side wall portion 107 forming the side surface of the fitting receiving portion 71. Since the signal fixing piece 27 having a thickness larger than that of the combined pieces 25 and 26 is attached, the light emitting panel 2 is bent or wobbled as compared with the fitting state of only the feeding fitting pieces 25 and 26 and the fitting receiving portion 71. Can be suppressed.

  According to the mounting structure 1 of the light emitting panel of the first embodiment, the panel-side power supply terminals 32 and 33 are separated from each other because the notch 30 is divided into two power supply fitting pieces 25 and 26 that contribute to power supply. It is possible to supply power independently of positive and negative without contact. Therefore, a short circuit due to contact of the panel-side power supply terminals 32 and 33 can be prevented, and safety is high.

  According to the light emitting panel mounting structure 1 of the first embodiment, power is supplied from the mounting device 3 to the light emitting panel 2 using the fitting relationship between the panel side fitting portion 11 and the mounting side fitting portion 56. Therefore, the light emitting panel mounting structure is simple and safe and reliable for the user.

  According to the light emitting panel mounting structure 1 of the first embodiment, since the blocking portion 78 is provided so as to block a part of the insertion opening 74, the user may accidentally insert other members such as an SD card into the insertion opening. 74 can be prevented from being inserted.

  According to the light emitting panel mounting structure 1 of the first embodiment, coil springs with tapered tips are used as the mounting-side fixing portions 52 and 53, and the mounting-side fixing portions 52 and 53 are fixed to the fixing holes 45 and 46, respectively. Therefore, the light emitting panel 2 can be prevented from dropping unexpectedly.

According to the light emitting panel mounting structure 1 of the first embodiment, the feeding fitting pieces 25 and 26 are moved from the inner side (center side) to the outer side (end side) in the surface direction of the light emitting panel 2. Therefore, when the power supply fitting pieces 25 and 26 are attached, a force is applied to the frame portion 10. Since the reaction force of the frame portion 10 at this time works inward, the organic EL panel 6 is pressed by the frame member 5. Therefore, the integrated strength of the organic EL panel 6 and the frame member 5 is high, and the organic EL panel 6 is not easily detached from the frame member 5.
Further, according to the light emitting panel mounting structure 1 of the first embodiment, since the reinforcing member 7 is provided on the back surface of the organic EL panel 6, the feeding fitting pieces 25 and 26 are attached to the fitting receiving portion 71. Since the reinforcing member 7 receives a load due to bending at the time, the strength is high and the organic EL panel 6 is hardly damaged.

  In the light emitting panel mounting structure 1 of the first embodiment, the mounting device 3 can change the posture between a parallel posture and a crossing posture, and can support the light emitting panel 2 in any of the parallel posture and the crossing posture. Therefore, for example, the light-emitting panel can be used as illumination in a crossed posture. That is, the posture of the light emitting panel 2 can be changed according to the layout, and the decoration is high.

  According to the light emitting panel 2 of the present embodiment, the light emitting side cover 15 is located on the light emitting surface 8 side, and the size of the outer edge of the light emitting side cover 15 is smaller than the size of the outer edge of the back side cover 17. Therefore, the width of the frame member 5 can be made narrower to the user. Moreover, since the end surface cover part 16 inclines, it can prevent that the light emission panel 2 contacts with another light emission panel in rotation operation | movement.

  Next, the light emitting panel mounting structure 150 according to the second embodiment will be described. In addition, the thing similar to 1st Embodiment attaches | subjects the same number, and abbreviate | omits description.

  The light emitting panel mounting structure 150 of the second embodiment is different in structure from the mounting device 3 of the first embodiment.
