Cornering tool

Abstract

This product is a fastener that can protect and hold the corners of paper and fix it to a wall. As shown in Reference Figure 1-2 of the usage situation, it is composed of a transparent resin sheet and a thumbtack. Reference Figure 3 of the usage situation shows how to insert the four corners of the paper into the slots and fix it to the wall by inserting the pin on the back. As shown in the enlarged cross-sectional view AA in the reference figure for the front, the disc part of the thumbtack is wrapped in the sheet, so when inserting paper into the slots, the paper does not get caught on the disc part of the thumbtack and can be inserted smoothly. In addition, the bulge of the inner folded part holds the paper in place, creating a force to hold the paper when it is inserted. It can be easily removed by simply pulling it out. It can be fixed to the wall without making holes in the paper, and if the paper is the same size, it is easy to replace, and it does not increase the number of holes in the wall caused by thumbtacks.
