Description

  The present invention relates to a sign mounting structure for mounting a sign.

  The sign is usually attached to a sign mounting bracket. For example, as shown in FIG. 32, a caution mark 120 is fixed to a mark mounting bracket 110 installed on the ground with a bolt 131 and a nut 132. At this time, a double nut is used in which two nuts 132 are overlapped so that the bolt 131 is not detached and the caution mark 120 is securely attached.

  At a later date, when replacing the attention sign 120, the total number of nuts 132 will be removed. Since the time required for replacing the caution mark 120 requires about 4 minutes for removing the nut and tightening each, a total time of about 8 minutes is required. Further, when replacing the caution sign 120, a tool such as a spanner is required to remove the nut 132. Furthermore, when the nut 132 is tightened, if the marker mounting bracket 110 and the bolt 132 are narrow, it is difficult to tighten with a tool such as a spanner.

  Therefore, a flat display device for attaching a sign or the like without using a nut has been proposed (see, for example, Patent Document 1). According to this apparatus, since the thread groove is formed in advance in the portion to which the mark or the like is attached, a nut is not necessary.
