  However, there is a concern that the bar will gradually come out of the engagement part due to the traffic of the car or vibration due to the use over time, if the bar is only press-fitted. There was a risk of falling to pedestrians and automated persons who travel underneath.

  In view of the actual situation as described above, the present invention prevents unintentional removal of the bar from the engagement location between the panel constituent members, and visually shows the state of the engagement location to the parties concerned and third parties. It is to provide a display panel that can be easily confirmed.

  The invention according to claim 1 of the present invention is a display panel for engaging a plurality of panel constituent members arranged in a line in the vertical direction or the left-right direction, and one and the other panel constituent members adjacent to each other. On the side where the two abut each other has either an engaging part or an engaged part, and the engaged part and the engaged part are in contact with each other and face each other. Each insertion hole forming groove is provided and both insertion hole forming grooves face each other to form an insertion hole. The insertion hole has a length substantially the same as the hole length of the insertion hole and substantially the same as the hole diameter. A bar having a width is inserted, and each groove wall portion of both the insertion hole forming grooves) is formed in a bent shape or a curved shape on the outer peripheral side of the insertion hole, and on the inner peripheral surface. The thin wall portion is provided, and both groove wall portions are deformed toward the inside of the insertion hole when the respective outer peripheral surfaces are pressed. The inner peripheral surface of the part, characterized in that the tightening variable by pressing respectively the bar from opposite sides.

The invention according to claim 2 of the present invention is characterized in that the bar has a substantially rectangular cross section.
The term “substantially rectangular shape” as used herein means that each end face of the bar is formed as a substantially flat surface, and includes, for example, a rounded square shape.

  In the invention according to claim 3 of the present invention, the bar is formed slightly shorter than the hole length of the insertion hole, and when the bar is inserted into the insertion hole and the groove wall portion is tightened The portions of the groove wall portion that extend beyond the bar are respectively closed with a space therebetween, and the two holes of the insertion hole cannot be pulled out.

  According to the first aspect of the present invention, the bar material is put into the insertion holes of the two adjacent panel constituent members, and the outer peripheral surfaces of the both groove wall portions forming the insertion holes are pressed with a tool or the like. By deforming, the bar can be securely fastened to the engaging portion of both panel constituent members. As a result, the bar does not easily come out of the insertion hole, and overhead safety for a person passing under the display panel such as an automobile or a pedestrian is ensured.

  According to the invention described in claim 2 of the present invention, when the bar has a substantially rectangular cross section, the bar is inserted into the insertion hole and the outer peripheral surfaces of both groove walls are pressed and tightened. In addition, since the rod has a substantially rectangular cross section, the rod does not rotate about the longitudinal axis in the insertion hole due to vibrations or the like that the rod receives during use. The escape from the is prevented. In addition, it can be easily seen from the outside that the deformed both groove walls are tightened to the flat end face of the bar without any gaps, so it is visually confirmed that the bar is difficult to pull out from the insertion hole. As a result, the safety of the display panel can be widely understood not only by construction personnel but also by third parties such as passersby.

  According to invention of Claim 3 among this invention, the site | part extended rather than the bar material by the side of the hole opening of a groove wall part is formed of a bar material by forming a bar material shorter than the hole length of an insertion hole. It can be tightened so as to cover the end in the longitudinal direction. As a result, the rod does not inadvertently come out of the insertion hole, and the insertion hole is only narrowed in the hole, so that both end surfaces in the longitudinal direction of the rod can be viewed from outside the insertion hole. Since the third member can visually confirm that the bar does not come out of the insertion hole, the display panel with higher safety can be provided.

It is a side view of the panel structural member 2, (d) is a perspective view of the bar 6, (e) is a side view of the bar 6. FIG.
As shown in FIGS. 4A and 4B, the present display panel A is applied as a road sign as an example. Specifically, the display panel A extends horizontally to the upper part of the main pillar 10 that stands vertically from the ground. Two columns 11 and 11 are arranged with a space in the vertical direction, and a plurality of panel constituent members 1 and 2 are vertically engaged with the columns 11 and 11 by a reinforcing member 13 and a fixture 14 in the vertical display. Panel A is attached.

Of the plurality of panel constituent members 1 and 2 constituting the display panel A of the present invention, as shown in FIG. 2 (a), one of the panel constituent members 1 and the other panel constituent member 2 adjacent in the vertical direction. A description will be given by excerpting the configuration of only two sheets.
The one and other panel constituent members 1 and 2 are arranged such that one side wall portions 1a and 2a are arranged in parallel on the side located on the display side, and the other side wall portions 1b and 2b are arranged in parallel on the side located on the non-display side. Small side wall portions 1c, 1d, 2c and 2d are provided at both ends in the vertical direction of the portions 1a and 2a and the other side wall portions 1b and 2b so as to connect the one side wall portions 1a and 2a and the other side wall portions 1b and 2b. It is. As described above, the display panel A according to the present embodiment is a hollow structure having a substantially rectangular shape when viewed from the side, and the present embodiment uses a hollow extruded shape obtained by extrusion.
In addition, the display panel A of the present invention is not limited to the number of the panel constituent members 1 and 2 that are arranged to be engaged with each other, and is not limited to that shown in FIG. Accordingly, the number of connecting panel constituent members 1 and 2 is appropriately changed.

One and the other panel constituent members 1 and 2 are “grooved” on the non-display side as shown in FIG. 2A in the present embodiment, and “no groove” as shown in FIG. Among them, those with “grooves” are attached to the column 10 on the non-display side of the substantially middle part in the vertical direction of the panel constituent member 2 as shown in FIGS. 4 (a) and 4 (b). A concave groove 12 extending in a substantially horizontal direction for fitting the reinforcing member 14 is provided.
On the side walls 1d and 2c on the side where one and the other panel constituent members 1 and 2 abut each other, a vertical piece 3a, 4a and a horizontal piece extending in a substantially horizontal direction from the tip of the vertical piece 3a, 4a A pair of engaging portions 3 or engaged portions 4 each having a flange shape composed of 3b and 4b are divided into two portions of the panel component members 1 and 2 near the one side wall portion 1a and the other side wall portion 1b. It is provided at each location.
And the engaging part 3 and the to-be-engaged part 4 are regulating that the horizontal components 3b and 4b mutually overlap in the up-down direction, and both panel structural members 1 and 2 are separated from the up-down direction. Further, the groove wall portion 7a, between the two engaging portions 3 and 3 or the two engaged portions 4 and 4 at the two small edge side wall portions 1d and 2c of each of the panel constituting members 1 and 2 is provided. 7b is provided with insertion hole forming grooves 5a and 5b that are recessed in a substantially "U" shape on the outer peripheral side, and there are other holes at the substantially central position in the left-right direction of the inner peripheral surface U of the groove walls 7a and 7b. Thin wall portions 9a and 9b that are thinner than the portion are provided.
Thereby, when one and the other panel constituent members 1 and 2 adjacent to each other are engaged with each other, both the insertion hole forming grooves 5a and 5b face each other vertically, An insertion hole 5 having a substantially hexagonal shape surrounding the four sides is formed from the groove wall portions 7a and 7b, the vertical piece 3a of the engaging portion 3, and the vertical piece 4a of the engaged portion 4. 2 (d) and (e), by inserting a bar 6 having a substantially rectangular cross section, the left and right end surfaces 6c and 6d of the bar 6 are respectively in contact with the horizontal pieces 3b and 4b described above. In contact with each other, the unexpected axial rotation of the longitudinal axis of the bar 6 in the insertion hole 5 becomes substantially impossible.

The engagement state of the adjacent one and other panel constituent members 1 and 2 will be described in detail below.
As shown in FIG. 1B, the outer peripheral surface T of the groove wall portions 7a and 7b with respect to the groove wall portions 7a and 7b of the small edge side wall portions 1d and 2c of the one and the other panel constituent members 1 and 2 is used. Is pressed in the direction toward the insertion hole 5 using a tool such as pliers, for example, stress is concentrated on the thin wall portions 9a and 9b of both the groove wall portions 7a and 7b, and the inner wall is deformed. The bar 6 is tightened by the inner peripheral surfaces U of both the groove wall portions 7a and 7b. As a result, the upper and lower end surfaces 6a and 6b of the bar 6 are pressed by both groove walls 7a and 7b so as to be sandwiched from above and below, and finally the upper and lower end surfaces 6a and 6b of the bar 6 and both groove walls The portions 7a and 7b abut against and press against each other between the flat surfaces, and the above-described vertical pieces 3a and 4a of the engaging portion 3 and the engaged portion 4 are in contact with the left and right end surfaces 6c and 6d of the bar 6. All the end faces 6a, 6b, 6c, 6d of the bar 6 can be fastened together with the locations.

  As described above, by tightening the bar 6 in the insertion hole 5, for example, the display panel A according to the present embodiment receives wind pressure, and stress is concentrated at the engagement portion, and one and the other adjacent to each other are connected. When the two panel constituent members 1 and 2 are about to rotate around the engaging portion, the inner peripheral surface U of the insertion hole 5 and the four end surfaces 6a, 6b, 6c and 6d of the bar 6 are substantially flat. Since it press-contacts in a state, the fastening strength of the bar 6 becomes extremely high. In addition, since the four end surfaces 6a, 6b, 6c, 6d of the bar 6 are all tightened in a state where they are in contact with each other with substantially flat surfaces, for example, external forces such as vibration transmission and wind pressure due to vehicle traffic This makes it difficult for the bar 6 to rotate about the longitudinal axis inside the insertion hole 5, so that the possibility of unexpected withdrawal due to various factors such as the aging of the display panel A according to the present implementation is extremely low. In addition, when viewed from either the left or right side of the display panel A according to the present embodiment, it can be seen from a third party that the bar 6 is tightened in a state of substantially matching the entire inner circumferential surface U of the insertion hole 5. Therefore, the display panel A according to the present embodiment can be said to be visually safe.

As shown in FIGS. 3A and 3B, the display panel A according to the present invention is made shorter than the hole length of the insertion hole 5 by making the bar 6 shorter than the bar 6 of both the groove wall portions 7a and 7b. When the extended portions 7c, 7d on the opening side of the insertion hole 5 that extends also can be tightened, the extended portions 7c, 7d of the groove wall portions 7a, 7b are both ends in the longitudinal direction of the bar 6 It is possible to narrow the hole width of the insertion hole 5 on the side of the open ports Ha and Hb by covering the portion with the gap R provided. As a result, the bar 6 inserted into the insertion hole 5 is not inadvertently pulled out, and it can be confirmed from a third party that the bar 6 is inserted into the insertion hole 5. It can be seen at a glance that it is in a state where it cannot be removed from the insertion hole 5, and the safety of the display panel A can be confirmed visually.
In this embodiment, as shown in FIG. 3 (b), a plurality of locations K of the groove wall portions 7a, 7b near the open holes Ha, Hb of the insertion hole 5 are pressed more strongly than the other portions with a tool or the like. Then, the inner peripheral surface U of the groove wall portions 7a, 7b of the portion is tightened so that it deeply penetrates into the upper and lower end surfaces 6a, 6b of the bar 6, and thereby the tightening strength of the bar 6 Is further strengthened.

  The display panel A of the present invention can be applied to, for example, a store signboard or a guide sign other than the road sign illustrated in the present embodiment. Further, in the claims and the present embodiment, the display side of the display panel A is set to the display side and the non-display side, but this expression includes, for example, one side and the other side, or the inside of the store and the outside of the store. Such a relationship is also included. Further, the thin wall portions 9a, 9b provided on the inner peripheral surface U of the groove wall portions 7a, 7b of both the insertion hole forming grooves 5a, 5b are partially thicker than the other portions of the groove wall portions 7a, 7b. Since what is necessary is just to make thin, it does not restrict | limit shape and magnitude | size, such as a hollow shape and groove shape, for example. Further, the portion where the thin wall portions 9a and 9b are provided is not limited to the substantially central position of the inner peripheral surface U of the groove wall portions 7a and 7b as in the present embodiment, and the groove wall portions 7a and 7b are deformed to the inner peripheral side. It should just be in the position where it is easy to do.
