Embodiment Construction

[0031] Some preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Figures 1 to 3 A lockable slider for a zipper according to a first embodiment of the present invention is shown. The sliding head is an automatic locking sliding head, which has a sliding head body 1 , a pulling piece 2 and a yoke 3 . And a locking pawl 4 made of elastic strips. Such as figure 2 and 3 The zipper shown has a pair of facing snap strips F, on which a pair of snap element rows E are attached to respective inner longitudinal sides of a pair of snap strip backing strips T, T by sewing threads S, respectively. ( image 3 ).

[0033] Sliding head body 1 has a pair of upper and lower wings 5,6 which are parallel and spaced apart, and is connected with a guide post 7 at its front end so that a substantially Y-shaped guide channel is formed between the two wings 5,6 so that The fasteners E, E of the two rows facing ea...

Abstract

A lock slider, for a slide fastener, includes an upper wing having an interior surface adapted to be in contact with a pair of fastener tapes, and a wedge-like ridge projecting from the interior surface of the upper wing and extending from a guide post toward a rear end of the upper wing for spreading open the respective closely abutting inner longitudinal edges of the fastener tapes. The upper wing further has, in its interior surface, a recessed portion extending around the fore end portion and the stem for for allowing the inner longitudinal tape edges to be displaced into the recessed portion when they are spread open by the ridge. An aperture for the passage of a locking pawl is formed in the upper wing at an intermediate portion of the ridge. By virtue of the combination of the ridge and the aperture, the abutting inner longitudinal tape edges are sufficiently spread open, and the locking pawl comes into locking engagement with the fastener elements inside the slider without interference with the tape edges.

Description

technical field [0001] The present invention generally relates to a lockable slider (lock) for a zipper of the type having a mechanism capable of manually or automatically locking the slider in any position on the zipper, and more particularly to a particularly suitable For the lockable slider of the so-called concealed zipper, the back strip of this zipper is arranged on the back of the garment together with the part where the fastener is installed. Background technique [0002] A known lockable slider for this type of zipper is disclosed in Japanese Utility Model Publication No. Sho 63-5533. Such as Figure 7 As shown, the disclosed lockable slider has a step 20 protruding from the center of the inner surface of the upper wing 5' and extending from the guide post 7' to the rear end 8' of the upper wing 5' in the longitudinal direction so as to be used to press the lock member of the zipper , also has an eyelet 13' on one side of the step 20 so that the locking pawl can pa...
