Japanese Utility Model Publication No. 7-26882

  In view of the above background art, an object of the present invention is to provide a signboard that is easy to attach and detach a panel, has a small finding width of a frame for fixing the panel, and can have a large display portion.

The signboard according to the present invention includes a frame body, a panel, a presser, and a fixing screw, the frame body has a panel receiving portion and a frame body female screw hole, and the panel has a recessed shape having an opening toward the frame body side. The presser has a panel presser and a presser female screw hole, and is arranged on the inner peripheral side of the panel opening, and is prevented from rotating with respect to the frame body. The fixing screw has a small pitch thread portion with a small screw pitch on the head side, a large pitch thread portion with a large screw pitch on the tip side, and the small pitch screw portion of the fixing screw is screwed into the female screw hole on the frame body. The large pitch screw part is screwed into the presser female screw hole, and the panel holding part is sandwiched between the panel receiving part of the frame and the panel presser part of the presser.
For example, at least two-stage screw with the fixed screw head side as the large-diameter screw portion and the tip end side as the small-diameter screw portion, the screw pitch of the large-diameter screw portion is made smaller than the screw pitch of the small-diameter screw portion, and the fixed screw When the small pitch screw part is screwed into the frame female screw hole, the large pitch screw part is screwed into the presser female screw hole, and the fixing screw is turned in the tightening direction, the amount of movement of the presser with a large screw pitch is greater. It is larger than the amount of movement with respect to the frame body, and the distance between the frame body and the presser is reduced, and the sandwiching portion of the panel located therebetween is sandwiched.
In the present invention, the small pitch screw portion and the large pitch screw portion refer to a relative pitch comparison.

In the present invention, the panel has a concave shape having an opening toward the frame body, and has a sandwiching portion at the opening edge, so that the panel can be detached from the front of the signboard, and the width of the frame can be found. It can be small, and the panel display can be enlarged accordingly.
In addition, since the panel is sandwiched by a movement in which the space between the frame body and the presser is narrowed in conjunction with the rotation of the fixing screw, the number of parts is reduced compared to the conventional combination type of the frame and the display frame.

As an embodiment of the signboard according to the present invention, FIG. 3 shows an external view of a round sleeve signboard and FIG. 4 shows a cross-sectional view taken along line A1-A1.
FIG. 5 is an external view of the stand signboard, and FIG. 6 is a cross-sectional view taken along line A2-A2.
