Description
Technical field
The present invention relates to fastener for thin thread, this fastener for thin thread has through hole, is configured in drawstring on clothes or the bag etc., stay cord or big belt (below be referred to as cord) and can passes its through hole, at the state that cord is pulled out from through hole it is blocked and anti-avulsion.
Background technology
This kind fastener for thin thread divides from preventing the structure that cord is deviate from, have helical spring type and in wheeled two classes.Fig. 7 represents the former conventional example, is made of the Lock Part 32 that bottom tube-like body 30 and coherent through hole 32a are arranged of coherent through hole 30a.This Lock Part 32 is pushed towards projected direction by the springs 31 in a part of body 30 of can packing into with haunting.State from Fig. 7 (a), Lock Part 32 pushed make two through hole 30a, 32a aim at (being the releasing cord position of Lock Part 32), being located at after cord 40 on clothes etc. passes the through hole 32a of Lock Part 32 from side's opening of base side through hole 30a, be pulled out to the outside from the opposing party's opening of base side through hole 30a.After cord passes, discharge the power that pushes away Lock Part 32 down, shown in Fig. 7 (b), Lock Part 32 is pushed to by spring 31, and through hole 32a and base side through hole 30a stagger.Like this, cord 40 is held under the arm between the lower edge of the upper limb of through hole 30a and through hole 32a, with the effect of the corresponding clamping power of the elastic force of spring 31 under, cord 40 deviate to be prevented from.
Fig. 8 is the latter's a conventional example.Width dimensions between the both sides 35a of body 35 attenuates towards the other end from an end, has the sliding tray 35b of middle left and right directions.Lock Part 36 has takes turns 36a in the circle, middle wheel 36a with both sides 35a circular arc portion in opposite directions on, form the tooth 36b of portion.Cord 41 is from the releasing cord position of the Lock Part 36 of Fig. 8 (a), from body 35 one distolateral by take turns between 36a and the side's sidewall 35a after, shown in Fig. 8 (b) in another distolateral wraparound, in passing again between wheel 36a and the opposing party's sidewall 35a.From this state, when another distolateral cord stuck position moved, cord was by between each 36b of tooth portion and respective sides 35a of wheel 36a in being held under the arm along sliding tray 35b for Lock Part 36, and it deviates to be prevented from.
Above-mentioned existing fastener for thin thread, in the structure shown in Figure 7, spring 31 is made by metal or resin, though the latching force for the cord tearaway load is strengthened with spring force with being directly proportional,, strengthened spring force after, the power that pushes Lock Part 32 also increases, so operability is bad.In addition, in the position that Lock Part 32 blocks cord 40, two through hole 30a, the 32a of body 30 and Lock Part 32 stagger, and cord 40 is forced to bending because of staggering of hole.When cord is the big elastic cord of diameter, get back to a linear state because of the recuperability of elastic cord, at this moment Lock Part 32 just can not remain on the position of blocking cord, and perhaps latching force weakens.In structure shown in Figure 8, though that the past more cord stuck position of Lock Part 36 moves its latching force is strong more,, being locked power correspondingly, latched position staggers, and can not block at the position that cord is pinned in hope.The operation that connects of cord is distolateral distolateral to another from body 35, in walking around again wheel 36a get back to one distolateral, so use inconvenient.In addition, in appearance, its integral body is flat, the size L between the cord cord penetrate oral-lateral with in take turns 36a and increase with being directly proportional, be not suitable for clothes etc., the scope of application is restricted.
