Abstract
A throwing star target is provided, in which a throwing star easily sticks and which has excellent durability. A throwing star target 1 which holds a thrown throwing star 2 includes a board 10 , and a plurality of pins 20 arranged on a target surface 10 A of the board 10 . Each of the plurality of pins 20 has a polygonal XY cross section, is formed to be tapered, and has flat surfaces 20 U, 20 V, and 20 W which come into contact with a front side 2 A or a back side 2 B of the throwing star 2 that is in a state in which of being held.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A throwing star target which holds a thrown throwing star, the throwing star target comprising:
a board; and a plurality of pins arranged on a target surface of the board, wherein each of the plurality of pins has a polygonal cross section, is formed to be tapered, and has a flat surface which comes into contact with a front side or a back side of the throwing star that is in a state of being held.
2 . The throwing star target according to claim 1 , wherein
the plurality of pins are arranged at regular intervals on the target surface along a first direction, a second direction, and a third direction each obtained by rotation by 120° about an axis perpendicular to the target surface, each of the plurality of pins has a first surface which is formed along a fourth direction obtained by rotating the first direction about the axis by 90°, a second surface which is formed along a fifth direction obtained by rotating the second direction about the axis by 90°, and a third surface which is formed along a sixth direction obtained by rotating the third direction about the axis by 90°, in a pair of the pins which are adjacent to each other, the first surface of one of the pins and the first surface of the other of the pins face each other, with a gap being formed therebetween, and the gap at tip portions of the pins is greater than a plate thickness of the throwing star and the gap at holding portions of the pins, which are closer to the board than the tip portions are, is smaller than the plate thickness of the throwing star.
3 . The throwing star target according to claim 2 , wherein
each of the plurality of pins includes a shape of a hexagonal frustum or a hexagonal prism constituted of a pair of the first surfaces, a pair of the second surfaces, and a pair of the third surfaces.
4 . The throwing star target according to claim 3 , wherein
each of the plurality of pins further includes a fillet portion which is smoothly contiguous with the target surface, and the fillet portions each have an outer edge formed into a hexagonal shape and are arranged without any space therebetween on the target surfaceJoin the waitlist — get patent alerts
