Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a pull tab of a slider for a slide fastener, and more particularly to a pull tab made of a hard material such as metal or hard synthetic resin.

[Conventional technology]

In the slider for a slide fastener, for example, when trying to tighten the fastener with a lot of baggage put in the bag, a lateral pulling force is applied to the fastener tape, so that sliding resistance becomes relatively large. Therefore, since the twisting, bending, and shearing stresses act on the connecting portion between the pull tab and the slider body, the pull tab needs strength, and the pull tab has been conventionally made of metal or hard synthetic resin.

However, since the pull tab is made of metal or hard synthetic resin, it feels cold and does not feel good on the skin when picked by hand. Also. Since sliding resistance works on the slider, there was a risk that the hand would slip.

Therefore, when pulling the puller, the slider can be surely slid without slipping the fingers, and the circumferential groove provided on the side wall surface is provided on the inner peripheral edge of the hole in the hole formed at the tip of the puller. Japanese Utility Model Laid-Open No. 60-60912 discloses a non-slip body in which upper and lower surfaces on which concave and convex portions are formed and which are fitted and which are respectively fixed to the upper and lower surfaces of a pull tab body are fixed.

(Problems to be Solved by the Invention) In this conventional pull tab, a circumferential groove provided on a side wall surface of a non-slip member is fitted into an inner peripheral edge of the bore in a hole bored at a tip portion of the pull tab, and the pull tab is slid. The upper and lower surfaces of the stopper, on which the concave and convex portions are formed, are respectively fixed to the upper and lower surfaces of the pull tab main body by penetrating.

However, for example, when the slider using the pull tab is used for a fastener attached to a jumper, a large force is applied from the back side of the pull tab to the front side when the slider is slid from bottom to top. Also, when lowering the slider,
On the contrary, a large force is applied from the front side to the back side of the puller. In this way, when pulling the pull tab, a large force is applied from one of the upper and lower sides of the anti-skid body, and if the sliding resistance of the slider is large, the anti-slip phase provided in the pull tab will fall out.

In addition, the pull tab may remain upright with respect to the slider body, but especially in the case of a slide fastener attached to sportswear, when pulling it down and pulling it upright, The area around the tip may be injured by a hand or body. As described above, the irregularities around the tip of the pull tab may cause an injury or the like when it is unexpected.

Further, when the conventional pull tab is attached to the adherend as a fastener, there is a problem that the irregularities around the tip of the pull tab make sliding contact with the adherend and damage the cloth of the adherend.

This invention has been made in view of the above circumstances, and its purpose is to smoothly slide the slider without pulling an excessive force on the fingertip when pulling the tab of the puller and sliding the slider. In addition, it can be pulled reliably, and even if the sliding resistance of the slider is large, the knob of the puller will not fall out, there will be no risk of injury to the hand or body, and the fabric of the adherend will not be damaged. There is no thing.

(Means for Solving the Problem) In order to achieve the above object and solve the problem, the present invention provides a pull tab main body (11) and a slider main body (11) provided at a proximal end portion of the pull tab main body (11). In the pull tab (1) of the slider for a slide fastener, which is made of a hard material such as a metal or a hard synthetic resin, which is composed of a pillar (21) of 2) and a connecting portion (13) having a through hole (12) that engages with the pillar, A knob mounting portion (15) is formed by forming a through hole (14) at the tip of the main body (11), and the knob mounting portion (15) is filled with the through hole (14) and attached by a knob. A knob (16) made of a soft synthetic rubber or a soft synthetic resin having a high flexibility and elasticity, which covers the entire surface including the outer contour of the part (15), is formed, and the knob (1)
The problem is solved by this structure in which the upper part of 6) is provided with a turning-up preventing means between the knob and the mounting part (15).

(Operation) Since the present invention is configured as described above, when pulling the tab of the puller and sliding the slider, the frictional resistance between the finger and the tab is large, but the fingertip slides without excessive force. Without pulling, even if the slider has a large sliding resistance, the pull-out preventing means prevents the pull tab from falling off.
In addition, even if the pull tab is upright with respect to the slider body and touches your hand or body, the soft synthetic rubber or soft synthetic resin that is full of flexibility and elasticity that covers the entire surface including the outer contour of the knob attachment part Since it is formed, there is no fear of injury and the fabric of the adherend is not damaged.
