As this type of signboard, there is a signboard described in Patent Document 1, for example. This standing signboard has a structure in which the lower ends of a pair of front and back frames that are rotatably connected at the upper end sides are widened to stand up. By connecting the lower ends, the spread of the interval on the lower end side is restricted to a predetermined angle. Stability is improved by connecting the lower ends of both frames with the bottom frame.

However, especially on highways and the like, stability cannot be maintained only by the connecting structure with the bottom frame due to strong winds. For this reason, in the standing signboard of Patent Document 1, the upper and lower intervals of the display plate attached to the front frame are opened to allow the wind to pass through, thereby reducing the wind pressure resistance.
In addition, a projecting plate extending beyond the space between the lower ends of the front and back frames is mounted so as to straddle the lower frame members of the front and rear frames, and a weight such as a sandbag is placed on the projecting portion of the projecting plate.

Utility Model Registration No. 3213742

However, in the upright signboard described in Patent Document 1, the overhang plate on which a weight such as a sandbag is placed has a positioning structure corresponding to the restriction of the spread of the interval on the lower end side by the bottom frame, so the restriction width by the bottom frame is different. Standing signs cannot share the same overhang.
That is, the overhang plate for countermeasures against strong winds described in Patent Document 1 is dedicated to one-to-one correspondence with the standing signboard for which it is used, and cannot be shared with the standing signboards having different sizes of the spread of the space on the lower end side of the frame. rice field.
If it can be used for signboards of different sizes, it will contribute to cost reduction and facilitate storage management when not in use.

Further, the bottom frame 31 includes a plurality of narrow plates 37 arranged and fixed between the brackets 33 and 35 at intervals in the direction of the arrow X, and an L-shaped engaging member fixed downward to the free end side of the bottom frame 31 . A stop piece 39 and the like are provided.
The portion of the locking piece 39 that protrudes downward is locked to the outer surface of the lower lateral frame 25 of the rear frame 5, thereby restricting the gap between the lower ends of the front frame 3 and the rear frame 5 from increasing any further. be done.

One end of an elongated arm 41 is rotatably provided on the lower lateral frame 25 of the rear frame 5, and the other end of the arm 41 is rotatably connected to the outer surface of the bracket 33 of the bottom frame 31. . The same applies to the other bracket 35 as well.
When the bottom frame 31 is unlocked from the lower lateral frame 25 of the rear frame 5 by the locking piece 39 and pushed toward the front frame 3 while rotating upward, the rear frame 5 overlaps the front frame 3 . It folds up into a compact configuration.

As shown in FIG. 1, weight rods 43 are detachably attached to both sides of the signboard 1 so as to connect the lower end sides of the front frame 3 and the rear frame 5, which are a pair of frames. The weight rod 43 has a structure that can be used for left and right by simply changing the direction.
Hereinafter, the configuration of the weight rod 43 will be described in detail with reference to the drawings.

FIG. 2 shows the state of the weight rod 43 during storage or transportation.
The weight rod 43 has a core member 45 (see FIG. 3) extending in the direction of widening the space between the lower ends of the front frame 3 and the rear frame 5 .
Cylindrical members 49 and 51 are fitted to the core member 45 so as to be slidable in the axial direction, and an inverted U-shaped hook 47 as an engaging member is attached to the lower ends of the pair of frames, the front frame 3 and the rear frame 5 . are detachably attached via the
Butterfly bolts 53 as fixing members are provided on the pair of cylindrical members 49 and 51, respectively, and fix the cylindrical members 49 and 51 to the core member 45 at arbitrary positions.
The pair of tubular members 49 and 51 are positioned axially outside the core member 45 beyond the distance D (see FIG. 1) between the lower ends of the front frame 3 and the rear frame 5 in a state where they are fixed by butterfly bolts 53 . It is provided to extend to

The two weight rods 43 attached to both sides of the signboard 1 have a tubular member 49 attached to the lower end of the right vertical frame 9 of the front frame 3 on the right side, and a tubular member 51 attached to the right vertical frame 9 of the rear frame 5 . 21 at the lower end.
On the left side, the position of the hook 47 can be reversed, so that the tubular member 49 is attached to the lower end of the left vertical frame 19 of the rear frame 5 and the tubular member 51 is attached to the left vertical frame 19 of the front frame 3 . It is attached to the lower end of the frame 7 .

The core member 45 and the cylindrical members 49 and 51 have a regular octagonal (regular polygonal) cross-sectional shape, and are made of an aluminum alloy. As a result, the core member 45 and the tubular members 49 and 51 are both strong and lightweight. Further, the polygonal shape of the core member 45 and the tubular members 49 and 51 improves the ease of gripping during handling.
The core member 45 has a rail-shaped groove 45a extending in the axial direction (direction of arrow X). A pair of male screws 46 functioning as stoppers are attached to the longitudinal central portion of the bottom surface 45a-1 of the groove 45a. When the cylindrical members 49 and 51 are slid toward each other, a nut 57a (to be described later) comes into contact with the male screw 46, so that the cylindrical members 49 and 51 are stopped at substantially the center of the core member 45. there is
The length L1 of the pair of tubular members 49 and 51 butted against each other in the axial direction of the core member 45 is substantially the same as the length L2 of the core member 45 (see FIG. 3).

Referring to FIGS. 4 and 5, the configuration of fixing the cylindrical members 49 and 51 to the core member 45 and the like will be described using the cylindrical member 51 as a representative.
As shown in FIG. 4A, the nut 57a is fixed to the cylindrical member 51 and accommodated in the groove 45a.
The butterfly bolt 53 has a threaded portion 53a that is screwed into a nut 57a housed in the groove 45a of the core member 45. The tip of the threaded portion 53a comes into contact with the bottom surface 45a-1 of the groove 45a, thereby tightening the core member 45. The tubular member 51 is fixed to the .

The hook 47 is fixed to a plate 59 arranged on the outer surface of the tubular member 51 .
The two nuts 57b are fixed to the tubular member 51 and housed in the groove 45a.
The plate 59 is fixed to the tubular member 51 with two bolts 61 that are screwed onto the nuts 57b.
In order to prevent the tubular member 51 from falling off from the core member 45 during transportation or the like, the outer end in the axial direction is also fixed with an eyebolt 55 in this embodiment.
The eyebolt 55 has a threaded portion 55a that is screwed into a nut 57c housed in the groove 45a of the core member 45, and the tip of the threaded portion 55a abuts against the bottom surface 45a-1 of the groove 45a, thereby tightening the core member 45. The axially outer end portion of the tubular member 51 is fixed to the .

When using the weight rod 43 from the state shown in FIG. 2, as shown in FIG. to
Further, as shown in FIG. 5B, the eyebolt 55 is loosened so that the tip of the threaded portion 55a is separated from the bottom surface 45a-1 of the groove 45a.

With the cylindrical members 49 and 51 released from the core member 45, as shown in FIG. 6, the cylindrical members 49 and 51 are slid away from each other.
Then, while adjusting the positions of the tubular members 49 and 51, as shown in FIG. The hook 47 of the cylindrical member 51 is engaged with the ring 63a of the eyebolt 63 fixed to the lower end of the right vertical frame 21 of the rear frame 5, and the weight rod 43 is erected on the right side of the signboard 1. Attach to After attachment, the wing bolts 53 are tightened to fix the tubular members 49 and 51 to the core member 45 .

The weight rod 43 is installed on the floor surface (road surface) F on which the signboard 1 is installed.
In FIG. 7, reference numeral 65 indicates a nut. The dimension t is preferably several mm to 1 cm.

Since the weight rod 43 has a structure common to both the left and right sides, when it is attached to the left side of the signboard 1, it can be attached in the same manner with the direction of the hook 47 reversed.
When the weight rods 43 are attached to the left and right lower ends of the signboard 1 as described above, the pair of cylindrical members 49 and 51 are positioned and fixed by the wing bolts 53, respectively, as shown in FIG. It is provided so as to extend axially outward of the core member 45 by a distance E exceeding the distance D between the lower end portions of the frame 3 and the rear frame 5 .

The dimension E is set to a length that allows a weight such as a sandbag to be placed stably. Even for signboards 1 with different intervals D, that is, different sizes, the difference in size is absorbed by the sliding of the cylindrical members 49 and 51 on the core material 45, so that one weight rod 43 can cope with the difference in size. It is possible to obtain a constant portion of dimension E for placing weights such as.

Since one weight rod 43 can be shared by the standing signboards 1 of a plurality of sizes, the cost can be reduced as a countermeasure against strong winds, and the storage management when not in use is facilitated.
In addition, when not in use as described above, the cylindrical members 49 and 51 can be butted together to form a compact contracted structure, which facilitates carrying and handling and contributes to space saving during storage.

FIG. 8 shows a state in which a deformable sandbag 67 containing sand or the like is placed on the portion of dimension E of the cylindrical members 49 and 51 . By doing so, it is possible to prevent the standing signboard 1 from falling down due to a strong wind.
Each sandbag 67 is anchored to the signboard 1 by fixing the end of a wire 69 as a linear member passed through the hand-held portion 67a to eyebolts 55 and 63. - 特許庁In this case, if a one-touch locking member such as a carabiner hook is attached to both ends of the wire 69 so as to be locked to the eyebolts 55 and 63, the work can be performed quickly and easily.

The eyebolt 55 serves as a fixing member that fixes the cylindrical members 49 and 51 to the core member 45 in cooperation with the butterfly bolt 53 as described above. The eyebolts 55 are weighted at the axially outer ends of the core members 45 of the pair of tubular members 49 and 51 and at the portion of dimension E extending beyond the distance D between the lower ends of the front frame 3 and the rear frame 5 . It becomes a locking member that locks a wire 69 as a wire material that restrains the sandbag 67 when the sandbag 67 is placed thereon.

The sandbag 67 may be further placed on the intermediate portion 71 of the weight rod 43 where the core 45 is exposed or on the bottom frame 31 to further improve stabilization. In this case as well, a tethering configuration similar to that described above can be employed.
A rope 75 having a carabiner hook 73 at one end is locked to the intersection of the right vertical frame 21 and the upper horizontal frame 23 of the rear frame 5, and the other end of the rope 75 is connected to a nearby guardrail post or rail plate. The signboard 1 may be prevented from being blown away by winding it around an immovable structure such as the like.

Although not shown in FIG. 1 and the like, actually, as shown in FIG. 9, on the display board 17, characters such as "restriction of continuous construction" and arrows indicating traffic directions are displayed in different colors. ing. In addition, a large number of small holes 17a are formed in the entire area of the display plate 17 from the viewpoint of wind pressure reduction to such an extent that the display is not obstructed.

Although the embodiments of the present invention have been described in detail above, the specific configuration is not limited to these embodiments, and the invention may be modified without departing from the gist of the invention. include.
For example, in the above embodiment, the pair of cylindrical members 49 and 51 are provided with the hooks 47 as engaging members, and the lower ends of the front frame 3 and the rear frame 5 are provided with the eyebolts 63 for engaging the hooks 47. However, instead of the eyebolt 63, a hole may be formed in which the hook 47 is engaged.
Alternatively, opposite hooks 47 may be formed on the lower ends of the front frame 3 and the rear frame 5, and rings or holes may be formed on the cylindrical members 49 and 51 for engagement. That is, the engaging member provided on the tubular members 49 and 51 may be either a hole or a ring provided between the lower ends of the front frame 3 and the rear frame 5 and a hook hooked thereon.
The material of the cylindrical members 49 and 51 is not limited to the above, and synthetic resin may be used.
