Chuck head of hand-throwing toy and chuck dart using same

Abstract

The invention discloses a chuck head of a hand-throwing toy and a chuck dart using same. The chuck is made of soft foaming composite material which has the following components: 35-45% of polyvinyl acetate, 10-20% of ethylene vinyl acetate, 10-20% of nitrile rubber, 5-15% of polyethylene and 15-25% of calcium carbonate; the invention also discloses a chuck dart using the chuck which provides moreforceful guarantee for safety of children when playing; the dart can still stick to the chuck even if the surface thereof is relatively coarse; as a result, playing site and space for chuck-like toysis substantially expanded; the chuck can automatically comes off after sticking to the dart for a while, reducing dissatisfaction of parents; even if the dart is thrown at a very small angel, the chuck can still stick to the target dart, further increasing amusement.

Description

technical field [0001] The invention relates to a part of a hand-throwing projectile toy, in particular to a suction cup head of a hand-throwing projectile toy; the invention also relates to a suction cup dart using the suction cup head. Background technique [0002] Suction cups made of natural rubber were first used in projectile toys in the early twentieth century. Toy darts and toy arrows with suction cups on the head have the following unique advantages: (1) The suction cup is like a large and blunt rubber arrowhead. The toy darts with suction cups are not easy to hurt people when they are shot, so they are relatively safe for children in play. Children's safety is provided with appropriate protection; (2) Unlike other toys with blunt structures, toy darts or toy arrows with suction cups can be pasted on hard and smooth surfaces, so dart toys with suction cups are more durable than ordinary toys. Pure head toys can provide more and excellent play value to children in p...

AI Technical Summary

Problems solved by technology

[0005] (1) Suction cups made of traditional materials have good adhesion to hard, flat and smooth target surfaces (such as window glass, iron doors of refrigerators, etc.), but for semi-flat surfaces (such as cement walls, painted and unpainted) Polished wooden doors, etc.) and uneven and rough surfaces, the suction cups made of traditional materials cannot fit well with such surfaces, so that they cannot lock the air pressure difference inside and outside the suction cups, resulting in poor adsorption. Therefore, the suction cups are completely Can't stick to the target surface, or can only stay for one to two seconds and then quickly detach

This feature greatly limits the space for children to play with suction cup toys, and also limits the play value of children when they play

[0006] (2) Based on the above reasons, in addition to using more elastic traditional synthetic materials, toy manufacturers pay more attention to the structural improvement of the suction cup when designing the suction cup. Strong suction, but still not much help on less flat and rough surfaces

If it is projected at a small angle to the target surface, in most cases the suction cup toy can only bounce back from the target surface to the ground and cannot stick to the target surface, which limits the fun value when children play
