  Further, in the flat display device mounting bracket described in Patent Document 2, when the flat display device is unlocked and pulled out for maintenance or the like, the link mechanism is lowered to support the weight of the flat display device by the link mechanism. There is a possibility that the upper flat display device will be rubbed due to bending. In particular, since the flat display device constitutes a large screen, the outer frame (bezel) of the liquid crystal panel is thin and small, so that the lower flat display device may be rubbed and damaged. Further, since the outer frame is thin and low in strength, it is not preferable to operate it manually by pulling out the flat display device.

  The present invention has been made in view of such problems, and it is intended to provide an attachment for a display device that prevents the display device from coming into contact with other display devices when the display device is pulled out. Objective.

And a guide member provided on one of the base and the support frame and extending toward the other, and provided on the other of the base and the support frame and sliding along the guide member. The sliding member and the guide member are separated from each other at a position exceeding a distance corresponding to the thickness of the display device when the support frame is pulled out.
According to the display device fixture of the present invention, when the display device is pulled out in the direction away from the base, the support frame on which the display device is mounted is supported by the sliding member and the guide member being in contact with each other and relatively sliding. Therefore, it is possible to prevent the display device from lowering due to the load of the display device and bending or drooping. Therefore, even if another display device is attached to the lower side, the upper display device contacts the lower display device. To prevent or collide. In addition, even with a single display device, the sliding member and the guide member can prevent the support frame from being lowered by the load of the display device immediately after it is separated from the base, so that the display device can be smoothly pulled out. Similarly, when the support frame at the drawer position is returned to the substrate, the sliding member and the guide member are similarly slidably supported.

In addition, an engagement receiving portion is provided on one of the base and the support frame, an engagement portion that can be fitted to the engagement receiving portion is attached to the other, and the engagement portion is engaged at the position where the link mechanism is contracted. It is characterized by being fitted to.
When the link mechanism is contracted and the support frame on which the display device is mounted is positioned on the base side, the support frame can be firmly supported by fitting the engagement portion to the engagement receiving portion provided on one of the base and the support frame. .

In addition, the slide shaft provided in the link mechanism is slidable along a guide groove that guides expansion and contraction of the link mechanism, and the first wire connected to the support frame is passed through the first pulley provided on the base. Connected to the first operating portion and a second operating portion to which a second wire connected to the sliding shaft is connected via a second pulley provided on the base, and operates the first operating portion. Thus, the display device is moved from the drawing position to the base side, and the display device is pulled out from the base by operating the second operation unit.
According to the present invention, it is possible to perform maintenance of the display device by operating the second operation portion to pull out the support frame on which the display device is mounted by moving the second wire in a direction away from the base. By operating one operation unit, the first wire is activated and the support frame on which the display device is mounted can be moved to the base side. Therefore, when a large display screen is formed by arranging a plurality of display devices in the vertical and horizontal directions, the display device can be pulled out without touching it directly and maintenance can be performed.

  According to the display device mounting tool of the present invention, when one display device is pulled out for maintenance or the like in a state where a plurality of display devices are arranged in the vertical and horizontal directions, after the thickness distance of the other display device is exceeded. Since the sliding member and the guide member are disengaged, it can be prevented from colliding with or coming into contact with another display device.

  Further, a fixing member 35 is rotatably attached to a support shaft 34 planted at one end at the upper part of the base 3, and a fitting pin 35 a provided at the other end of the fixing member 35 is provided at the upper part of the base 3. Is fitted in a hole provided in Then, with the support frame body 4 pulled out, the fixing member 35 is rotated about 90 degrees around the support shaft 34 to fit the fitting pin 35 a into the hole 4 a provided in the upper part of the support frame body 4. The support frame 4 can be held in the pulled out state.

In addition, brackets 37 for clamping a cable (not shown) of the display device 1 are provided on the upper side of the latch plates 8 on both sides of the base 3 so as to protrude on both the left and right sides. Similarly, brackets 38 are also provided on the left and right sides of the support frame 4 so as to protrude on both the left and right sides. Therefore, it can hold | maintain without getting in the way by hooking the power cable, the signal cable, etc. which were connected to the display apparatus 1 to each bracket 37 and 38, and latching.
Moreover, as shown in FIGS. 1-3, the operation bar 40 is attached to the lower part of a pair of latch plate 8 via the chain | strand. In the fixed position where the support frame 4 is pulled back to the base 3, the concave groove 8 a of the latch plate 8 is detached from the pin 16 by pulling the operation bar 40 downward.

The fixture 2 of the display device 1 according to the present embodiment has the above-described configuration, and a method of using the fixture 2 will be described with reference to FIG.
In FIG. 7 (a), a plurality of display devices 1 are each mounted on a fixture 2 and held on a wall surface, and a large display screen is formed by arranging the plurality of display devices 1 in close contact in the vertical and horizontal directions. One image can be displayed as a whole. The support frame 4 on which each display device 1 is mounted is held at the retracted position in contact with the base 3.

For example, when the upper display device 1 is to be pulled out for maintenance, when the operation bar 40 is lowered, the concave groove 8a of the latch plate 8 is detached from the engagement pin 16, and the inclined guide portion 8b of the latch plate 8 is lowered. Then, the engagement pin 16 provided on the support base 6 is pushed to advance the engagement pin 16 and the support frame 4 from the position of the groove 8a. Then, by pulling down the second operation portion 32, the second wire 30 is pulled, and the sliding shaft 17 b provided on the center link 17 of the link mechanism 5 and the sliding shaft 18 b provided on the side link 18 constitute the rear front angle 9. And the guide groove 15a of the front front angle 15 respectively rise.
As a result, the link mechanism 5 rotates around the shaft portion 19 in the direction in which the center link 17 and the side link 18 approach each other and extends in the horizontal direction, and pulls out the support frame 4 on which the display device 1 is mounted forward. Therefore, the force which pulls down the 2nd operation part 32 can be reduced because the support frame 4 advances by operation of the operation bar 40. FIG.

Then, the support frame 4 is pulled forward from the pull-back position on the base 3 side, and the sliding roller 12 provided on the support frame 4 slides on the guide member 10 provided on the base 3, thereby supporting the support frame. 4 is supported by the link mechanism 5 and the guide member 10 while sharing the load. Then, as shown in FIG. 7B, the sliding roller 12 disengages the guide member 10 at a position where the upper display device 1 exceeds the distance of the thickness of the lower display device 1, so that the load on the display device 1 is increased. Is supported by the link mechanism 5 alone, the link mechanism 5 becomes slightly small and the display device 1 moves downward.
At this time, since the upper display device 1 is positioned in front of the lower display device 1, the upper display device 1 does not contact the lower display device 1.

  Thereafter, the pulling position where the sliding shaft 17b of the center link 17 and the sliding shaft 18b of the side link 18 of the link mechanism 5 are in contact with the respective upper ends of the guide groove 9a of the rear front angle 9 and the guide groove 15a of the front front angle 15. The support frame 4 is cantilevered by the link mechanism 5 at this position. In this state, the fixing member 35 is rotated about 90 degrees from the base 3 around the support shaft 34 and moved onto the support frame 4, and the fitting pin 35 a is inserted into the hole 4 a formed in the support frame 4. Fit. Then, maintenance such as repair and inspection and position adjustment of the display device 1 can be performed without or without removing the display device 1 from the support frame 4.

  Next, after the maintenance is completed, the first operation unit 28 is pulled down in order to attach the display device 1 at the pull-out position to the support frame 4 and return it to the pull-back position. Then, the first wire 26 is pulled and the support frame 4 is moved to the base 3 side, so that the link mechanism 5 is contracted. The slide shafts 17b and 18b of the center link 17 and the side link 18 of the link mechanism 5 descend from the upper end to the lower end along the guide grooves 9a and 15a of the rear front angle 9 and the front front angle 15. Then, in the retraction movement of the support frame body 4, the link mechanism 5 is halfway and the slide roller 12 of the support frame body 4 rides on the tip of the guide member 10 provided on the base 3 from a position where the slide roller 12 is slightly lowered. Since it slides at height, it can prevent that the display apparatus 1 contacts the lower display apparatus 1 also in a pull-back process.

When the support frame 4 approaches the vicinity of the base 3, the latch pin 8 descends against the urging force of the spring 11 because the engaging pin 16 presses the inclined portion of the peak portion 8c of the concave groove 8a. Get over Yamabe 8c. In addition, the engagement pin 16 is guided by the inclined guide portion 8b, and is engaged with the concave groove 8a in conjunction with the operation of the latch plate 8 returning to the original position by the urging force of the spring 11.
In this way, the support frame 4 on which the display device 1 is mounted is returned to the pull-back position on the base 3 side. In addition, since the engaging pin 16 is pushed upward by the concave groove 8a by the urging force of the spring 11, it is accurately positioned and fixed.

  As described above, according to the fixture 2 of the display device 1 according to the present embodiment, in order to perform maintenance of the central display device 1 or the upper display device 1 when a plurality of display devices 1 are arranged in the vertical and horizontal directions. When pulling out, the support frame 4 on which the display device 1 is mounted slides on the guide member 10 to a position exceeding the thickness of the lower display device 1, so that the display device 1 is surely lowered downward by the load. It is possible to prevent the upper display device 1 from coming into contact with the lower display device 1. In particular, when a large display screen is constituted by a plurality of display devices 1, there is no risk of damage even if the outer frame (bezel) of the display screen of the display device 1 is formed thin. Further, the same effect can be obtained when the display device 1 is returned to the retracted position.

Further, even when only one display device 1 is mounted on the fixture 2, it is possible to prevent the display device 1 from drooping under its own load immediately after the engagement by the engagement pin 16 and the concave groove 8a is released. Therefore, the impact given to the link mechanism 5 can be suppressed.
Further, when the engagement pin 16 is fitted into the concave groove 8a, the support frame body 4 and the support base 6 are held at a predetermined height by the guide member 10 and horizontally moved. 16 can be securely fitted into the groove 8a. In addition, when the support frame body 4 is returned to the retracted position, the support frame body 4 is engaged with the concave groove 8a of the latch plate 8 with the engagement pin 16 fixed to the base 3, so that the urging force of the spring 11 is also compatible. Therefore, it can be locked at a predetermined position and no play occurs.

Further, when the support frame 4 with the display device 1 mounted is pulled out to the pull-out position or returned to the pull-back position, the operation can be performed simply by pulling down the operation lever 40, the first operation section 28, and the second operation section 32. Easy.
Further, conventionally, since the structure in which two sets of the link mechanism 5 are provided on both the left and right sides of the base board 3 is adopted, when the drawer is pulled out and pulled back, the link mechanism is independently operated without being synchronized, thereby deforming the display device. However, in this embodiment, since the link mechanism 5 is configured with high strength by one set, the link mechanism 5 is not deformed and the movement is smooth. High accuracy and no positional deviation.

In addition, the fixture of the display apparatus by this invention is not limited to embodiment mentioned above, A suitable change and substitution can be performed in the range which does not deviate from the summary of this invention.
For example, in the above-described embodiment, the guide member 10 is provided on the base 3 side and the sliding roller 12 is provided on the support frame body 4 side. Instead, the sliding roller 12 is provided on the base 3 side, and the support frame is provided. The guide member 10 may be provided on the body 4 side. In this case, the guide member 10 slides on the upper side of the sliding roller 12. Similarly, instead of the configuration in which the concave groove 8a is provided in the latch plate 8 on the base 3 side and the engagement pin 16 is provided on the support base 6 on the support frame body 4 side, the engagement pin 16 is provided on the latch plate 8 on the base 3 side. And a groove 8a may be provided on the support base 6 side on the support frame 4 side.
