The upper arm 11 is positioned by positioning the mounting portion 21 at a desired height position away from the upper portion 11, moving to the left, and inserting the positioning pin 24 into the positioning hole 11 a of the upper portion 11. The movement of the 20 leg portions 10 in the vertical direction is restricted, and the upper arm 20 can be disposed at a predetermined height position on the upper portion 11 of the leg portion 10 via the attachment portion 21. Further, the upper connecting member 31 is fitted on the notch upper end of the mounting portion 21 so that the upper connecting portion 31 and the lower connecting portion 32 cooperate to move the upper portion 11 to the right. In addition to restricting the movement, the upper part of the right side wall of the attachment part 21 restrains the attachment part 21 from moving the upper part 11 to the left and restricts the vertical movement of the upper arm 20.

  That is, the upper connecting portion 31, the lower connecting portion 32, the upper portion of the right side wall of the mounting portion 21, and the positioning pin 24 move the upper arm 20 away from the mounting target G in the direction in which the upper arm 20 approaches the mounting target G. The movement restricting means 30 of the present embodiment is configured to be fixed so as not to move in the direction and to restrain the vertical movement of the upper arm 20.

  The lower arm 54 has a substantially V-shaped plate shape in which a bracket 54b is fixed to a side surface of a sliding means 54a inserted on the outer side of the upper portion 11 and the lower portion 12 of the leg portion 10 and is opened upward at the tip of the bracket 54b. The engaging portion 54c is fixedly formed. The sliding means 54a is a cylindrical lower sliding portion 54aa that is externally fitted to the lower portion 12 of the leg portion 10 formed in a male screw shape, and extends from the sliding portion 54aa toward the upper portion 11 of the leg portion 10. The upper part 11 is formed by a rectangular cylindrical upper sliding part 54ab fitted on the upper part 11, and is slidable vertically along the upper part 11 and the lower part 12 of the leg part 10. Further, the upper sliding portion 54ab of the present embodiment has a substantially channel plate shape in which the entire left side wall is cut out and the front side wall (front side in the figure) and the rear side wall (back side in the figure) are connected by the right side wall. The right side wall, the front side wall, and the rear side wall are in close contact with the upper portion 11 of the leg portion 10 and can be externally fitted, and the channel portion 41 is mechanically connected from the front of the upper end to the left side and the rear side. And an upper connecting member 42 made of a reinforcing metal plate or the like. Since the left side wall portion of the upper sliding portion 54ab below the upper connecting member 42 is opened, the upper portion 11 and the lower portion 12 of the inner leg portion 10 can be visually confirmed from the outside. It can be confirmed that the leg portion 10 is securely inserted into the upper portion 11. A cushion material 54d made of an elastic material such as rubber is attached to the inner surface of the engaging portion 54c.

  Further, the nut 54e and the nut 54e which are screwed into the lower portion 12 and moved up and down to the lower end side of the lower sliding portion 54aa of the sliding means 54a and move the sliding means 54a up and down are positioned. A lock nut 54f is provided to prevent it. The lower arm 54 can be moved and arranged at an arbitrary height position along the upper portion 11 and the lower portion 12 of the leg portion 10 via the sliding means 54a and the nut 54e. Furthermore, the engaging portion 54c is freely engageable with the lower end of the attachment target G from below. As a result, the lower arm 54 is moved upward along the upper portion 11 and the lower portion 12 of the leg portion 10 in a state where the engaging portion 23 of the upper arm 20 is engaged with the upper end of the attachment target G, and the engaging portion 54c. Is press-engaged with the lower end of the attachment object G, so that the attachment object G is held between the upper arm 20 and the lower arm 54 from above and below.

  Next, the operation of the display plate fixture of the present embodiment configured as described above will be described.

  In order to post the display board S having the desired contents, the display board attachment of the present embodiment is attached to a desired position of the attachment target G such as a guard rail. In this case, in accordance with the width of the mounting object G, the mounting portion 21 is moved away from the upper portion 11 and moved to a desired height position and moved to the left to move the positioning pin 24 to the upper portion of the leg portion 10. The upper arm 20 is positioned at a desired height by being inserted in alignment with the positioning hole 11a at the predetermined height position 11. Furthermore, by attaching the upper connecting member 31 to the upper end of the cutout of the mounting portion 21, the mounting portion 21 moves to the right from the upper portion 11 by the cooperation of the upper connecting portion 31 and the lower connecting portion 32. Is restricted, and the upper part of the right side wall of the attachment part 21 restrains the attachment part 21 from moving leftward from the upper part 11 and restricts the vertical movement of the upper arm 20. Then, with the engaging portion 23 of the upper arm 20 engaged with the upper end of the attachment target G, the nut 54e of the lower arm 54 is tightened so that the sliding means 54a moves upward along the lower portion 12 of the leg portion 10. The engaging portion 54c is pressed and engaged with the lower end of the attachment target G, and the lock nut 54f is tightened to prevent the nut 54e from loosening. As a result, the mounting object G is sandwiched between the upper arm 20 and the lower arm 54 from above and below, and the display plate mounting tool is fixed to a desired position of the mounting object G. And the display board S which displays a desired content on the support part 52 is fastened and fixed with a fastener, and the posting of the display board S is completed.

  Here, when a strong wind W is applied to the display board S arranged in the direction Y substantially perpendicular to the attachment target G by the display board fixture, a force in the thickness direction X is applied to the display board S as in the conventional example. At the same time, the display plate S is in a direction intersecting the attachment target G by wind force, and a force in the direction Y substantially perpendicular to the attachment target G is simultaneously applied to the display plate S, and the display plate fixture is moved in the direction Y. May swing repeatedly.

  At this time, in the display plate fixture of the present embodiment, the upper arm 20 has the upper connecting member 31, the lower connecting member 32 of the movement restricting means 30, and the upper portion of the right side wall of the upper arm 20 with respect to the upper portion 11 of the leg portion 10. The upper arm 20 is fixed even if the display board S is repeatedly swung in the direction Y substantially perpendicular to the mounting target G because it is fixed so as not to move in the direction approaching the mounting target G and the direction separating from the mounting target G. However, it does not rattle by repeatedly swinging in the thickness direction of the upper end of the mounting target G. Further, the vertical movement of the upper arm 20 is restrained by the positioning pin 24, and the upper arm 20 is not displaced vertically from the predetermined height position where the upper arm 20 is positioned. The positioning pin 24 is not separated from the positioning hole 11 a of the upper portion 11 because the upper connecting member 31 restrains the rightward movement of the mounting portion 21. Therefore, there is no inconvenience that the upper arm 20 is detached from the attachment target G, and the display board S and the display board fixture are flying from the attachment object G.

  Furthermore, since the upper sliding portion 54ab of the sliding means 54a for supporting the lower arm 54 is inserted outside the upper portion 11 of the leg portion 10, the entire lower arm 54 rotates around the bracket 54b. This is reliably prevented, and the engaging portion 54c of the lower arm 54 is reliably prevented from being detached from the attachment target G. Thereby, the display board S and the display board fixture itself can be securely fixed to the attachment object G over a long period of time.

  When the display board S is attached to another place, the upper connecting member 31 is moved upward with a predetermined pressing force in the reverse procedure to the above, and the restraint of the attaching portion 21 is released, and the upper arm 20 Move up and down to reposition. Then, the display plate fixture is attached and fixed at a desired position of the attachment target G by the same procedure as described above.

  As described above, in the display plate fixture of the present embodiment, the leg portion 10 is disposed so as to extend in the vertical direction to the side of the attachment target G, and the display plate S can be supported on the upper end of the upper portion 11 of the leg portion 10. The support portion 52 is pivotally mounted at a predetermined rotational position, the upper arm 20 is externally fitted to the upper portion 11 of the leg portion 10 via the attachment portion 21, and the leg portion 10 is fixed by the positioning pin 24. The engaging portion 23 is freely engageable with the upper end of the mounting target G from above, and the lower arm 54 is screwed into the lower portion 12 of the leg portion 10 by a nut 54e. The upper and lower portions 11 and 12 of the leg portion 10 can be moved up and down via the sliding means 54a, and the engaging portion 54c can be engaged with the lower end of the mounting target G from below. Along the upper part 11 and the lower part 12 of the leg part 10 By moving, the mounting target G is held between the upper arm 20 from above and below, and the upper arm 20 is further moved toward the mounting target G with respect to the leg portion 10 and the A substantially square donut plate-like metal that is externally fitted to the upper end notch of the mounting portion 21 of the upper arm 20 with the movement restricting means 30 that restrains the movement in the direction away from the mounting target G and the vertical movement of the upper arm 20. The upper connecting member 31 having a plate shape, the lower connecting member 32 having a metal plate wound around the lower end, the upper right side wall of the mounting portion 21 and the positioning pin 24 are included.

  Therefore, in the present embodiment, the display plate mounting tool is supported by supporting the display plate S on the support portion 52 and engaging and holding the upper and lower ends of the mounting target G by the upper arm 20 and the lower arm 54. The display board S is posted at a desired position of the attachment target G. And when the wind W blows and the display board S is urged | biased not only in the thickness direction X but the width direction Y, the upper connection member 31, the lower connection member 32, and the attachment part 21 as the movement control means 30 are shown. The upper portion of the right side surface fixes the upper arm 20 to the leg portion 10 so as not to move in the direction approaching the attachment target G and the direction separating from the attachment target G, thereby preventing rattling. Further, the positioning pin 24 restrains the vertical movement of the upper arm 20 and prevents the vertical movement of the upper arm 20 from the predetermined height position where the upper arm 20 is positioned. As a result, even when the wind W is strong, it is possible to reliably prevent the problem that the upper arm 20 swings and is disengaged from the mounting target G, and the display plate mounting tool and the display plate S fly by the wind W. , Ensuring sufficient safety. Furthermore, since the upper sliding portion 54ab of the sliding means 54a for supporting the lower arm 54 is inserted outside the upper portion 11 of the leg portion 10, the entire lower arm 54 rotates around the bracket 54b. This is reliably prevented, and the engaging portion 54c of the lower arm 54 is reliably prevented from being detached from the attachment target G. Thereby, the display board S and the display board fixture itself can be securely fixed to the attachment object G over a long period of time.

  By the way, the movement restricting means 30 of the present embodiment is composed of the upper connecting member 31, the lower connecting member 32, the mounting portion 21, and the positioning pin 24. However, the present invention is limited to this. However, it is sufficient that the upper arm 20 functions to prevent the upper arm 20 from being detached from the leg portion 10 due to rattling. For example, the attachment portion 21 of the upper arm 20 is connected to the upper portion 11 of the leg portion 10. The mounting portion 21 can be configured to be prevented from rattling or swinging in the left-right direction by the entire right side surface and left side surface thereof. In this case, the positioning pin 24 can be configured to be screwed to the attachment portion 21 or the leg portion 10 from the outside of the attachment portion 21.

  Further, the sliding means 54a of the present embodiment is configured by the lower sliding member 54aa and the upper sliding member 54ab, but is not limited to this when implementing the present invention, and at least, The leg portion 10 may be inserted into both the lower portion 12 and the upper portion 11 and can be fastened with a nut 54e and a lock nut 54f. For example, the lower sliding member 54aa and the upper sliding portion may be used. The moving member 54ab may be divided into a rectangular tube that is fitted around the upper portion 11 of the rectangular tube without dividing the moving member 54ab, and the lower end portion thereof may be integrally formed as a bottom portion having a through-hole through which the lower portion 12 passes.

  FIG. 5 is an enlarged front view showing the attaching means of the display plate fixture according to another embodiment of the present invention.

  In the present embodiment, the movement restricting means 30 is composed of a square cylindrical mounting portion 21, and a through hole 11 b is formed in the leg portion 10. A nut is welded to the opposite surface (not shown) of the attachment portion 21. Therefore, the insertion position of the upper arm 20 can be determined by inserting the butterfly screw 40 into the through hole 11b of the leg portion 10 and screwing it.

  That is, the display plate fixture of each embodiment includes a leg portion 10 extending in the vertical direction on the side to be attached, a support portion 52 provided on the upper end portion of the leg portion 10 and supporting the display plate S, It is disposed in the movement restricting means 30 and the movement restricting means 30 that can freely restrain the movement in the direction approaching the attachment target G and the direction away from the attachment target G and the vertical movement with respect to the leg 10. The upper arm 20 that can be engaged with the upper end of the mounting object G from above and the lower part of the leg part 10 are inserted and can be moved in the vertical direction along the leg part 10. The lower arm 54 is engaged from below and holds the mounting object G in the vertical direction between the upper arm 20 and the lower arm 54.

  The configurations of the upper arm 20 and the lower arm 54 are not limited to those of the above-described embodiment, as long as the attachment object G can be held from above and below and the display panel fixture can be fixed at a predetermined position. For example, the engaging portion 23 or the engaging portion 54c may have another configuration such as a U-shaped plate shape.

  The upper arm 20 of the above embodiment is positioned and fixed at a predetermined height position of the upper portion 11 of the leg portion 10 by the positioning pin 24, and this is fixed in advance to the width of the attachment target G. In consideration of this, it can be fixed at a predetermined height position by welding or the like. Also in this case, the height adjustment by the vertical movement of the lower arm 54 can absorb the change in the width of the mounting object G, and the mounting is not hindered. According to this configuration, the positioning hole 11a of the leg portion 10, the insertion hole of the upper arm 20 and the positioning pin 24 can be omitted, and the overall configuration can be simplified and the cost can be reduced. . Further, the positioning pin 24 for positioning and fixing the upper arm 20 is inserted from the outside of the mounting portion 21 to the front side wall or the rear side wall of the upper portion 11 of the leg portion 10 as long as the mounting portion 21 can be prevented from falling off.
