Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention allows temporary installation on a guardrail, a guardrail pillar, or a gutter lid by a simple attachment means when there is no space to stand a sign support pillar on the side of a road. The present invention relates to a sign support device for various guide signs used during road construction.

[0002]

2. Description of the Related Art Conventionally, there have been provided a large number of sign supporting devices for various guide signs used for road construction or the like, which can be temporarily installed on a guard rail or a support of the guard rail. For example, in the case where various guide signs are attached to the guardrail or this pillar, the guard rail or the mounting bracket for mounting to this pillar is fixed by screwing means using fastening bolts, and the pillar of the sign is screwed to this mounting bracket. It is fixed by the stopping means. The screw means is securely mounted using a tool such as a spanner.

[0003]

In the sign support device for road construction or the like, since the fastening bolts are used in all of them, a tightening tool such as a spanner is required. In addition to spending time, several people are forced to work. This is because the number of temporary guide signs to be installed is several tens or more at the site of road construction, etc., and therefore it is most desirable to install them efficiently by one person.

Therefore, there has been proposed a sign support device in which the clamp mechanism is opened and closed by operating the lever so that the guide sign can be attached to and detached from the guardrail and this column by one-touch operation. However, the sign support device is complicated because the clamp mechanism is complicated. The manufacturing cost is high, and the mechanical parts often fail to function due to dust and the like at the construction site, and there is a problem that it cannot withstand use in a bad environment such as road construction.

The present invention was developed in view of the problems found in the above-described conventional sign support devices for road construction and the like, and provides a sign support device having both a simple structure and a simple attachment / detachment operability. The purpose is to
