DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device which is installed so that a signboard used as a sign for road works or the like is immovable.

[0002]

2. Description of the Related Art Various types of signs are installed in roads and other areas where construction is performed. For example, there are various types of signs, such as a signboard indicating the period of the construction, a signboard indicating the contractor, and a signboard indicating that the road is closed during the construction. FIG. 5 shows a general building sign used conventionally.
(B) has two legs (b) and (b), and the supporting legs (c) behind
Is mounted, and the signboard (a) is installed in a state of leaning slightly on the support leg (c).

[0003] However, this signboard is light and is misaligned when installed, and blows away when the wind blows. Therefore, in the past, heavy sand bags (d) and (d) were used to support the legs (d)
And placed at the lower ends of both legs (b) and (b) of the signboard (a). Of course, they may be placed in other places, but these sandbags (d) are heavy and inconvenient to carry, and when such sandbags are placed on the horizontal rail (e), they must be placed at the lower ends of the legs. In this case, the entire weight of the sandbag (d) does not act as a weight, and only a part of the weight acts effectively when it comes into contact with the ground.

The sand bag (d) often breaks when used, and if it is misaligned, the effect of acting as a weight may be lost. In other words, because the sandbags are not shaped, they have the advantage that they can be arranged in any way, but on the contrary, they have the disadvantage that the weight effect is reduced by half.
Sometimes it does not function as a weight at all.

[0005]

As described above, the conventional fixing device for a building sign has the above-mentioned problems. The problem to be solved by the present invention is this problem. It is convenient to carry, and it is necessary to fix the sign and the support leg of the signboard without wasting weight, and to install the signboard stably without displacement. Provide a signage fixing device that can do

[0006]

The sign fixing device of the present invention comprises a connecting seat plate for connecting the leg of the sign and the supporting leg, and a weight placed on the connecting seat plate. However, since the connecting seat plate is made of metal and heavy, it can be used without placing a separate weight. The connecting seat plate has a fixing portion at one end to which the lower end of the sign is fixed, and the fixing portion is attached so that its direction can be changed. And form a key at the other end,
The key and the support leg are connected to each other by being locked to the horizontal rail of the support leg, and the weight of the connecting seat plate acts on the support leg.

Here, there are cases where two connecting seat plates are used in pairs, or two fastening portions are attached to one connecting seat plate. The specific form of the fastening portion is not limited, and the attachment structure is such that the lower end of the leg is fixed and the direction of the leg can be changed so that it can be fixed regardless of the inclination angle of the leg. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 1 is an embodiment showing a connecting seat plate according to the present invention. The connecting seat plate 1 is composed of a seat plate 2 made of a metal plate having a predetermined width, a cylinder 3 and a key 4. The plate 2 is provided with a step 12 bent at the tip, and the tube 3 is attached to the tip. The cylinder 3 is a fastening portion to which the lower end of the signboard is fitted and fixed. The cylinder 3 is supported by support pieces 5 and 5 via a shaft pin 6 so that the direction of the cylinder 3 can be changed.

A thumb screw 7 is attached to the tip of the cylinder 3 so that the leg fitted into the hole of the cylinder 3 can be fixed so as not to come off. On the other hand, a U-shaped key 4 is provided at the rear end of the seat plate 2. FIG. 2 shows a case where the connecting seat plates 1 and 1 of the present invention are attached to a built signboard. Two connecting seats 1, 1 are used in pairs, the legs 9, 9 of the sign 8 fit into the cylinders 3, 3 of the respective connecting seats 1, 1, and the keys 4, 4 are the supporting legs 1.
0 is locked to the horizontal rail 11.

The legs 9, 9 fitted in the cylinders 3, 3 are thumb screws 7, 7,
And the support legs 10
By locking the keys 4 and 4 to 1, the legs 9 and 9 of the signboard and the support legs 10 are fixed at predetermined positions. The connecting seat plate 1 acts as a weight due to its large weight, and the key 4 is locked to the horizontal rail 11 so that the weight of the connecting seat plates 1 and 1 acts on the support legs 10. The reason why the step 12 is formed on the seat plate 2 is here. Only the tip provided with the cylinder 3 is in contact with the ground, and the other portion is floating from the ground, so that the weight of the connecting seat plate 1 is reduced. One half acts on the support leg 10. The signboard is therefore stable and will not be blown off by the wind. It goes without saying that the key 4 manufactured as a separate part is welded to the rear end of the seat plate 2.
It is also possible to form a key part in which the key fits.

In the embodiment shown in FIG. 2, two connecting seats 1, 1 are used in pairs and connect the respective legs 9, 9 to the supporting legs 10. And these connecting seat plates 1, 1
, Weights 13, 13 are placed on both connecting seat plates 1, 1. Therefore, the built signboard will be more stable. FIG. 3 shows a specific example of the weight 13, which is in the form of an elongated plate and has a handle 14 at the top.

By the way, the form of the fastening part for fixing the leg 9 of the signboard is not limited, and the above-mentioned cylinder 3 is only one specific example. Of course, it is convenient because it can be fixed simply by fitting the lower end of the leg to the cylinder 3 and screwing it. However, for example, a fastening structure as shown in FIG. 4 can be used. A support table 17 is attached to the support pieces 15, 15 via a shaft pin 16, and the support table 17 swings around the shaft pin 16 and can freely change its direction.

The support table 17 has a table 18 on which the legs 9 are mounted and a ring 19 at the upper end of a back plate 20 extending upward from the table 18. Therefore, the leg 9 is inserted from the ring 19 and
The foot 9 is fixed to the connecting seat plate 1 if the screw is provided on the ring 8 and the screw provided on the ring 19 is tightened. In the embodiment, 2
Although a case has been described in which the individual connection seat plates 1 and 1 are used as a pair, they may be configured as one connection seat plate. In this case, two fastening parts must be provided so that the two legs can be fixed.

As described above, the fixing device for a signboard according to the present invention comprises the connecting seat plate and the weight, and the connecting seat plate is engaged with the fastening portion for fixing the lower end of the signboard leg and the horizontal rail of the supporting leg. It has the key and the following effects can be obtained.

[0015]

The fixing device for a signboard of the present invention comprises a connecting seat plate and a weight. The connecting seat plate fixes the leg of the signboard at a fixing portion at the front end and is formed at the rear end. The key can be locked to the side rail of the support leg. Therefore, about 1 /
The weight of 2 acts on the horizontal rail, so that the signboard installed on the side of the road does not shift in position and, of course, is not blown off by the wind. That is, the legs of the signboard are fixed to the fixing portions that can change the angle freely according to the inclination of the legs and do not fall out, and the weight of the connecting seat plate acts on the support legs.

Unlike the conventional sandbag, the connecting seat plate is convenient to carry and can be used semi-permanently. If two connecting seats are used as a pair, they can be installed regardless of the width of the signboard. Furthermore, a separate weight can be placed on the connecting seat plate, and more stable installation is possible.
