2 is a front view showing a cut-out part of the concealed fastener equipped with the slider according to the present invention.

3 is an enlarged cross-sectional view of the arrow line A-A in FIG. 2;

4 is an enlarged cross-sectional view of the arrow line B-B in FIG. 2;

5 is a front view of a main portion showing the phenomenon that the tape, which occurred in the conventional concealed fastener, is seized.

The present invention relates to a slider used in a concealed fastener having a fastener stringer in which one end of a tape is bent and an element is sealed in various types of slide fasteners, and an object of the present invention is to perturb a slider. This is to prevent the tape end from being bited in the process and to obtain smooth perturbation.

As is well known, this kind of concealed fastener F 'has a tape shortest t outside of the sewing thread 8 which secures the element e of the fastener tape T as shown in FIG. ₃₎ there is pressed against the element (e), for example it rolled up ileukimyeon this portion (t ₃₎ strongly with a finger nail or the like. The conventional slider S 'attached to the concealed fastener F' has a shoulder wider than the width of the element row E on both sides of the slider guide 2 'at the front end of the body 1'. (4 '), an inwardly projecting end 6' bent from the outer wall 5 'of the body 1' is provided from the front end of the body 1 ', and an inwardly projecting end 6'. Since the inner edge 6a 'of the front end portion of the front end portion was formed in an arc shape and the inner edge 6a' was placed on the tape end portion t ₃ , the closing fastener F 'was closed. When the element e is twisted so that the head e ₁ of the element e is lowered and the corner e ₂ is increased when the element e is introduced into the slider S '. Since the tape shortest part t ₃ abuts on the circular arc surface of the said inner edge 6a ', and the circular arc surface acts like a guide, the tape shortest part t ₃ is guide | induced into the slider S'. It gradually curled up as caused by nails and flocked to the inner surface of the inwardly projecting end 6 'to increase the perturbation resistance of the slider S' or to make it difficult to perturb.

Therefore, the present invention is devised to solve the conventional drawbacks, and the slider according to the present invention will be described below in detail with reference to the accompanying drawings.

1 shows the slider S according to the present invention, and an element guide member 2 having a V-shaped tip portion is provided at the center of the front end portion of the body 1, and both upper ends of the tip portion of the guide member 2 are provided. It has the same element pressing body (2a) protruding in the same V-shape, and the structure in which the handle (3) is provided on the upper surface of the element guide (2) is the same as the conventional concealment fastener slider, but the moving body (1) The width a of the front end portion is formed to be approximately equal to the dimension obtained by adding twice the width a ₂ of the element rows E to the width a ₁ of the element guide ₂ . An outer wall 5, 5 is provided from the middle of the body 1 to the rear end, and the front end of the inwardly projecting end 6, 6 formed by bending the outer wall 5, 5 is an element. It is installed at the position where the guide body 2 has been retracted to the vicinity of the tip end, and the shoulders 4 and 4 are installed in a wide open state, and are integrally joined together like a Y-shape from the vicinity of the tip end of the element guide 2. An element guide groove 7 is formed, and the front end of the inwardly protruding end portions 6 and 6 is formed substantially parallel to the rear end of the body 1, and the front end of the inwardly protruding end portions 6 and 6 is formed. The inner edges 6a and 6a protrude more toward the element pressing body 2a than the passage position of the tape end portion t ₃ in the element guide groove 7, and the inner edge 6a and the element pressing body (2a) a gap is a proximity to some extent larger than the thickness of the tape (T) inverted (t ₂₎ of the installation between.

In the concealed fastener F equipped with the slider S, as shown in FIG. 2, the tape end t ₁ formed by bending one end of the fastener tape T has an element of the body 1. and guide grooves are fitted mounting in the (7), outside of the tape end (t ₁₎ of the outer tape shortest portion (t ₃₎ than sewing thread (8) for fixing the element rows (E) of the element guide groove (7) It is located near the wall 5 and farther away from the shear inner edge 6a of the inwardly projecting end 6.

Therefore, when the slider S is driven in the direction of the arrow shown and the left and right elements e and e are interlocked with each other, a strong lateral force is applied to the tape T as the elements e are guided in the direction of the occlusion. While the force acts on the shoulders 4 and 4, the elements e guided to the shoulders 4 are wide open without the inwardly protruding end 6, so that the above-described transverse forces The head (e ₁ ) is high and the angle (e ₂ ) is twisted low (see FIG. ₃ ) so that the height of the tape end portion (t ₃ ) pressed against the angle (e ₂ ) is inwardly projected (6). It is displaced lower than the height h of the inner surface of and is led downward of the inwardly protruding end 6 in the same posture. In addition, since the inner edge 6a of the inwardly protruding end 6 is provided close to the element pressing body 2a, the tape shortest end t ₃ does not face the inner edge 6a without the inwardly protruding end ( Passing below the front end of 6), the tape shortest part t ₃ is inserted below the inwardly projecting end 6 without curling. Subsequently, as shown in FIG. 4, the twisted element e is corrected in its posture by the element pressing body 2a, and then the opposing elements e and e interlock with each other.

As described above, the slider according to the present invention is provided at the position where the front end of the inwardly protruding end is retracted to the vicinity of the front end of the element guide member, and the front end of the body is provided with both sides wide open at about the same width as the width of the element row. Since the column of elements is twisted just before being inserted into the element guide groove, the tape shortest part is prevented from contacting the front end of the inwardly projecting end, and the inner edge of the front end of the inwardly projecting end is an element pressing member rather than the passing position of the tape end part. Since it is installed to protrude closer to the side, the tape shortest end is stuck to the outer wall of the front end of the inwardly protruding end without touching the inner edge, and there is no fear that the tape shortest end is rolled up, and the phenomenon of being bited out is prevented. Also, the smooth perturbation All.

Claims (1)

The front end of the inwardly protruding end 6 formed by bending the outer wall 5 of the body 1 is provided at a position where the front end of the element guide body 2 is retracted, and the element guide body at the front of the body 1 On both sides of (2), shoulders (4) (4) are formed to be wide open at about the same width as the row of elements (E), and the inner edge (6a) of the front end of the inwardly projecting end (6) is fastener tape ( t) of the tape shortest portion (t ₃₎ for the concealed slider fastener, characterized in that a further protruding out towards the pressure element than the apche (2a) of the passage position.
