摘要
The dart game was a game of throwing a winged pin on a corkboard.;Therefore, children are required to play darts that can be played with children and adults without risk because the pins are so sharp that they can be injured if thrown incorrectly.;A dart game was developed by attaching velcro (aka: whip) to a dart board made of sponge material and making a ball made of nylon material called Kotrich (Ny Rex) in a ball shape to replace the conventional dart game.;The present invention is a technology designed to improve the portion of the dart game material.;Conventional technology has been made by attaching a cotton cloth in several pieces of sewing stitches in this case, but in this case, the final finishing step has to be sewn by hand, in which case the seams protrude out, the appearance is not beautiful. In addition, due to the large number of manual labor costs, manufacturing costs are high and quality cannot be maintained at a certain level.;The present invention compensates for the disadvantages of the prior art by molding the shape of the ball by plastic injection and attaching the coatrich on it using double-sided adhesive to reduce the manufacturing process, thereby lowering the production cost to 1/3 compared to the previous. In order to maintain the development method different from the conventional manufacturing techniques.
