Document Type and Number:
Japanese Patent JP2018062166
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve a fastening tool that is integrally formed of a thumbtack and a magnet, which is convenient as it allows bulletin objects to be fastened both on soft and hard surfaces yet can cause an injury with a needle of the thumbtack if the thumbtack and the magnet are merely integrated.SOLUTION: Provided is a magnet thumbtack 1 in which a thumbtack having a needle 6 at a central lower end of a pressing part 5 is accommodated in a hollow part of a hollow cylindrical container 2A and a flat, ring-shaped magnet 3 is fitted to an upper end of a side part 8 of the container 2A. An iron disc-shaped object having an absorption property for the magnet 3 is used in the pressing part 5. When the thumbtack is not used for fastening a bulletin object, as shown in Fig. 2 (a), the pressing part 5 and the magnet 3 are constantly attracted to each other, that is, the thumbtack moves toward the upper end and becomes attracted, and thereby the needle 6 moves so as to be accommodated in the hollow part of the container 2A, so that safety is secured. When the thumbtack is used for fastening a bulletin object, as shown in Fig. 2 (b), the pressing part 5 is pressed from above in a P direction and the needle 6 is pushed out of the container 2A to fasten the bulletin object. When the magnet is used for fastening a bulletin object, the magnet 3 is used in a state shown in Fig. 2 (a) where the needle 6 is accommodated in the container 2A, so that safety is secured.SELECTED DRAWING: Figure 2
