[0013] (First Embodiment) Hereinafter, a thumbtack set 1 according to the first embodiment of the present invention will be described with reference to Figures 1 to 7. Figure 1 is a diagram showing an example of the overall configuration of the thumbtack set 1 according to this embodiment, Figure 2 is a diagram showing an example of a plan view of the thumbtack set 1 according to this embodiment, Figure 3 is a diagram showing an example of a side view of the thumbtack set 1 according to this embodiment, Figure 4 is a diagram showing an example of removing the thumbtacks 10 from the thumbtack set 1 according to this embodiment, Figure 5 is a diagram showing an example of the thumbtacks 10 according to this embodiment, Figure 6 is a view of Figure 5 from the X direction, and Figure 7 is a view of Figure 5 from the Y direction.

[0014] As shown in Figures 1 to 4, the thumbtack set 1 according to this embodiment includes a plurality of thumbtacks 10 and a housing member 20.

[0015] The housing member 20 is a member capable of housing a plurality of drawing pins 10. For example, the housing member 20 may have a pedestal shape as shown in FIG. 3. Further, the housing member 20 may be formed of resin.

[0016] As shown in FIGS. 2 and 3, the housing member 20 has an outer peripheral direction C, a height direction H, an upward direction U, a downward direction D, and a width direction W.

[0017] As shown in FIGS. 4, 5(a), and 5(b), each of the plurality of drawing pins 10 has a flat plate-shaped piercing portion 11 and a flat plate-shaped head 12 to which the piercing portion 11 is attached.

[0018] For example, the piercing portion 11 may be formed of metal, and the head 12 may be formed of resin.

[0019] As shown in FIG. 2, a plurality of holes 21 into which the piercing portion 11 can be inserted are provided along the outer peripheral direction C of the housing member 20.

[0020] According to such a configuration, since the piercing portion 11 of the drawing pin 10 can be inserted into the hole 21 and housed in the housing member 20, as shown in FIG. 4, the user can take out the drawing pin 10 from the housing member 20 without worrying about the piercing portion 11 piercing the finger during use.

[0021] Specifically, by piercing each of the drawing pins 10 into the housing member 20 in an annular shape, the piercing portion 11 is not exposed and the head 12 always faces outward, so the user can safely and easily take out the drawing pin 10.

[0022] Further, as shown in FIG. 3, the housing member 20 may have a first region R1, a second region R2, and a third region R3 arranged in the height direction H of the housing member 20. In the example of FIG. 3, three regions R1 to R3 are arranged in the height direction H, but the present invention is not limited to such a configuration and is applicable to a configuration in which any number of two or more regions are arranged in the height direction H.

[0023] As shown in Figure 3, in each of the first region R1, the second region R2, and the third region R3, the multiple holes 21 may be provided along the outer circumference direction C.

[0024] Furthermore, as shown in Figure 3, in a side view, the multiple thumbtacks 10 housed in the multiple holes 21 may be facing upward U with respect to the width direction W of the housing member 20.

[0025] With this configuration, the arrangement of the multiple thumbtacks 10 housed in the storage member 20 evokes the image of a flower (as shown in Figure 6, each thumbtack 10 corresponds to a petal), giving the thumbtacks 10, which tend to be stored at the back of drawers, a new sense of presence.

[0026] Furthermore, the thickness T11 of the insertion portion 11 of the thumbtack 10 is preferably in the range of 0.1 mm to 0.5 mm. As shown in Figure 7, the thickness T11 of the insertion portion 11 of the thumbtack 10 is more preferably 0.3 mm.

[0027] With the above configuration, by making both the insertion part 11 and the head 12 of the thumbtack 10 flat, the shape of the hole made when the thumbtack 10 is stuck into a wall becomes linear, making the puncture mark of the thumbtack 10 less noticeable, and preventing the thumbtack 10 from rolling and falling on a desk or the like.

[0028] Furthermore, with the above configuration, by making the insertion part 11 of the thumbtack 10 flat, it becomes easier to insert the thumbtack 10 into the wall, and the ability to hold it in place in the wall is also improved.

[0029] This configuration prevents the thumbtack 10 from rolling when placed on a desk or the like, and also prevents the insertion part 11 from facing upwards when the thumbtack 10 is dropped.

[0030] Furthermore, according to this embodiment, the number of thumbtacks 10 housed in the storage member 10 can be easily confirmed, making it easy to determine how many thumbtacks 10 are currently in use.

[0031] As shown in Figures 5 and 6, the insertion portion 11 consists of a first portion 11A including the tip 11T and a second region 11B located closer to the head 12 than the first portion 11A and continuous with the first portion 11A.

[0032] As shown in Figure 6, for example, the total length L1 of the thumbtack 10 is 24 mm. Also, as shown in Figure 7, for example, the length L11 of the insertion part 11 is 9 mm, and the length L12 of the head 12 is 15 mm.

[0033] As shown in Figure 6, in a plan view, the inclination angle with respect to the width direction W1 in the direction A from the tip 11T toward the head 12 (i.e., the inclination angle of both side edges of the first portion 11A toward the width direction W1) is preferably in the range of 45° to 150°. With such an inclination angle, it is easy to insert into a wall even if it is flat.

[0034] As shown in Figure 6, the width W11A / W11B of the second portion 11B may be configured to widen as it approaches the head 12. For example, the width W11B of the second portion 11B corresponding to the base of the insertion portion 11 is 5 mm. With this configuration, the strength of the insertion portion 11B, which is thin such as 0.3 mm in thickness, can be ensured.

[0035] As shown in Figures 5 and 7, the thickness T10 of the head 12 may be configured to increase towards the tip portion 12E. For example, as shown in Figure 7, the thickness T10A at the edge of the head 12 on the insertion portion 11 side is 2.7 mm.

[0036] As shown in Figure 6, the width W12 of the head 12 may be configured to widen towards the tip portion 12E (opposite side of the insertion portion 11). For example, as shown in Figure 6, the width W12A at the edge of the head 12 on the insertion portion 11 side is 9 mm, and the widest width W12B of the head 12 is 11.5 mm.

[0037] With this configuration, by widening the insertion portion 11 from width 11A to width 11B, it is possible to make it easier to insert the needle and to make the needle mark less noticeable, in addition to ensuring the desired strength and holding power.

[0038] With this configuration, by increasing the width W12 of the head 12 and the thickness T10 of the head 12 towards the tip portion 12E, it is possible to create a thumbtack 10 that is easy to insert the insertion portion 11 into a wall and easy to remove the insertion portion 11 from the wall.

[0039] (Example of change) Hereinafter, with reference to Figure 8, a modified thumbtack set 1 of the present invention will be described, focusing on the differences from the thumbtack set 1 of the first embodiment described above.

[0040] As shown in Figure 8, in the thumbtack set 1 according to this modified example, in a side view, the multiple thumbtacks 10 housed in the multiple holes 21 may be configured to face the width direction W of the housing member 20.

[0041] With this configuration, the arrangement of the multiple thumbtacks 10 housed in the storage member 20 resembles an ear of corn (each thumbtack 10 corresponds to a single kernel of corn), giving the thumbtacks 10, which tend to be stored at the back of drawers, a new sense of presence.

[0042] Furthermore, a magnet may be embedded in the lower surface D of the storage member 20. With this configuration, the storage member 20 can be attached to a metal wall or the like.

[0043] Furthermore, the storage member 20 may have the shape of a polygonal pyramid, such as a hexagonal pyramid. With such a configuration, it can be placed stably on a table.

[0044] Furthermore, by changing the number and angle of the holes 21 and the shape of the head 12, the arrangement of the multiple thumbtacks 10 housed in the housing member 20 may be structured to resemble not only flowers or corn as described above, but also pine cones, lions, hedgehogs, sea urchins, and the like.

[0045] As described above, the thumbtack set 1 according to the first embodiment and its modified examples has a design that mimics the shape of a plant (for example, a flower or corn) by housing the thumbtacks 10 in the housing member 20.

[0046] According to this embodiment, the puncture marks are smaller, so wallpaper and the like last longer. Also, according to this invention, the durability of the thumbtack 10 is improved, so the thumbtack 10 lasts longer. As a result, the amount of waste from wallpaper and thumbtacks 10 is reduced, which can contribute to SDG Goal 12, "Responsible Consumption and Production," Target 12.5, "Significantly reduce waste generation by preventing, reducing, recycling and reusing waste."

[0047] Although the present invention has been described in detail using the embodiments described above, it will be clear to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description herein is for illustrative purposes only and is not intended to be restrictive in any way to the present invention. [Explanation of symbols]
