Abstract: A dartboard includes a board frame and a plurality of target blocks coupled at the board frame. Each target block includes a block body, a predetermined amount of target materials, and a block panel. The block body has a material compartment and two openings aligning with the material compartment. The target materials are made of sisals and filled within the material compartment. The block panel is affixed to one of the openings of the block body to form a bottom panel of the respective block body so as to retain bottom of the target material within the material compartment of the block body.

Abstract: Disclosed is a target block of the dartboard, wherein said target blocks are assembled in the dartboard frame of the circle target blocks with different shapes, which can be replaced individually; the said interior target materials of the target blocks are made of sisals or similar materials. Through the formation mechanism, a predetermined amount of target materials (sisals) are disposed in the bottom of mounting seat applied with the adhesive in advance to joint the sisals and mounting seat as a whole. The target blocks put in the dartboard frame of the target blocks are in the centric circles and the same fan-shaped radial strip, which has two different colors at intervals to distinguish the blocks from each other.

Abstract: A dart includes a dart barrel, a shaft having a sliding end portion, and a dual action arrangement. The dart barrel has a head portion and a shaft channel coaxially extending at the head portion, and defining a head opening at the head portion to communicate with the shaft channel. The dual action arrangement includes a tubular shaft housing detachably mounted at the head opening of the dart barrel, wherein the shaft housing has a sliding slot coaxially aligning with the shaft channel for the a sliding end portion of the shaft sliding therealong. The tubular elastic element is coaxially mounted at the sliding end portion of the shaft for applying an urging force against an inner circumferential wall of the sliding slot so as to minimize a clearance between the sliding slot and the sliding end portion of the shaft.
