<Other embodiments of pull tabs>

Various embodiments of the pull tab for a slide fastener of the present invention will be described in detail with reference to the drawings. In the case of the slider 5 of the embodiment of the present invention, the slider 5 of the slide fastener 1A is rotatably held at one end. The pull tab 5 of the present invention includes an opening window portion 54 that forms a pair of cantilever locking tabs 55 for detachably engaging the tab release portion 36 provided on the slider body 2. .

The spacing of the pair of cantilever locking tabs 55 is slightly narrower than the width dimension of the left and right of the latching head 36b of the tab release portion 36. Therefore, if the pull tab 5 is intended to be engaged with the pull-tab release portion 36 and the pull-tab 5 is turned upside down, and the pull-tab release portion 36 is pressed, the pair of cantilever engagement tabs 55 are applied to The push of the pull tab 5 is temporarily widened by elastic deformation. Thereafter, when the pulling force is continuously applied to the pull tab 5, the pair of cantilever engaging pieces 55 pass over the detaching head portion 36b of the pull-tab releasing portion 36, and the left and right widths are equal to or smaller than the pair of cantilever engaging pieces 55. The neck 36a is spaced apart. At this time, the interval between the pair of cantilever engaging pieces 55 is restored to the original shape, and the engagement is completed.

In the present embodiment, the pair of cantilever engaging pieces 55 are the side end portions of the side wall portions surrounding the rectangular opening window portion 54 disposed on the front end 58 side of the pull-tab 5 as the base end, and are oriented toward the rotational axis side of the pull-tab 5 Extension. The base end of the pair of cantilever locking pieces 55 is not only the side wall portion of the side wall portion 54a surrounding the opening window portion 54 disposed on the front end 58 side of the pull tab 5, but may be a side wall portion disposed on the side of the rotating shaft, or It is the side wall of the left or right side. However, in order to form the performance of maintaining the basic structure of the slider on the one hand, the structure can be simply detached from the detachment head 36b of the handle body, and preferably, the base of the pair of cantilever locking pieces 55 is provided. The end is disposed on the front end 58 side.

In the present embodiment, each of the cantilever engagement pieces 55 includes a first locking piece portion 55a that is inclined to extend in a direction in which the distance between the base end side and the distal end side is widened, and a first locking piece portion The second locking piece portion 55b extending in parallel with each other at the front end of the 55a. Thereby, the cantilever engagement piece 55 is coupled to the side wall portion 54a from the oblique direction, so that the cross-sectional area at the boundary between the cantilever engagement piece 55 and the side wall portion can be increased, and the base of the cantilever engagement piece 55 can be reinforced. The cantilever locking piece 55 is elastically deformed repeatedly by the attaching and detaching operation of the pull-tab releasing portion 36. However, the durability of the elastic deformation can be improved by reinforcing the base of the cantilever locking piece 55. Further, the second locking piece portion 55b, which is a contact portion that comes into contact with the pull-tab releasing portion 36, is formed in parallel with the left and right side walls of the releasing head portion 36b of the pull-tab releasing portion 36, so that even the second card is formed. The contact portion of the stopper portion 55b and the pull-tab releasing portion 36 is slightly offset, and the force required for the fastening or pulling-off is hardly changed, so that a smooth detaching operation can be performed.

In the present embodiment, the first locking piece portion 55a is obliquely extended in a direction in which the distance between the first locking pieces 55a is widened from the proximal end side toward the distal end side, but may be reversed The distance between each other is obliquely extended from the base end side toward the front end side. However, if this is the case, there is an increase in the burden on the substrate during the loading and unloading operation, and in some respects, attention should also be paid to the spatial constraints.

Further, the cantilever locking piece 55 may be linearly extended from the base end to the front end without being bent in the middle. It may also be formed into a shape that is curved in the middle. It is also possible to change the thickness of the cantilever locking piece 55, for example, to increase the durability and to thicken the substrate.

Further, the pull tab of the present invention is attached to at least one of the pair of cantilever engaging pieces 55, and includes an anti-coupling projection 57 projecting toward the other of the opposite cantilever engaging pieces 55. By the presence of the anti-coupling convex portion 57, as shown in FIG. 3, the problem of the connection of the other tabs entering the opening window portion 54 can be prevented, so that the production efficiency is improved. Further, the anti-joining convex portion in the present invention may be simply referred to as a convex portion.

The anti-connection convex portion 57 may be provided only in the single cantilever locking piece 55 or in the cantilever locking piece 55 of both. However, the case where the anti-joining convex portion 57 is provided only in one of the cantilever locking pieces 55 or the anti-coupling convex portion 57 is provided in the cantilever locking pieces 55 of the two, when the cantilever locking pieces 55 are separated from the base end When the anti-connection convex portion 57 is provided at a different height from the different portions, it is necessary to increase the height of the anti-coupling convex portion 57 in order to obtain the desired anti-coupling effect, so that the problem of breakage is likely to occur. Moreover, there are also aesthetic problems caused by left and right asymmetry. Therefore, as in the case of the pull tab of the present embodiment, the anti-coupling convex portion 57 is preferably protruded from the cantilever engaging piece 55 of the two toward the oppositely facing cantilever locking pieces, and is preferably disposed. For each cantilever locking piece 55 The portions having the same distance from the base end are further preferably arranged bilaterally symmetrically. The apexes of the two anti-coupling projections 57 have a higher anti-coupling effect when they are as close as possible to each other. Therefore, the two can be bridged by the connection, but the cantilever locking piece 55 is opposite to the tab releasing portion 36. The loading and unloading resistance becomes large, so it is preferable that the vertices are separated from each other.

The anti-connection convex portion 57 is not particularly limited as long as it does not interfere with the portion where the cantilever locking piece 55 and the pull-tab releasing portion 36 are engaged. However, if the proximal end side of the cantilever locking piece 55 is excessively approached, the effect of preventing the connection is lowered. Therefore, the anti-coupling convex portion 57 is preferably provided on the front end side of the cantilever locking piece 55 as much as possible so as not to interfere with the engagement between the cantilever locking piece 55 and the pull-tab releasing portion 36. For example, as in the present embodiment, it is preferable to provide the boundary between the first locking piece portion 55a and the second locking piece portion 55b.

Further, it is preferable that the front end 58 of the pull tab 5 includes a ridge portion 59 which is protruded from at least one of the front and back surfaces in a direction perpendicular to the front and back surfaces. The reason for this is that the front end 58 of the pull tab 5 is difficult to enter the gap between the pair of cantilever engaging pieces 55. The ridges 59 may be disposed on only one of the front and back sides of the pull tab 5, or may be disposed on both sides of the front and back. However, since the function of the front and back of the pull tab 5 can be imparted, it is preferably provided. On only one side. Of course, as described below, if the distance C between the apexes of the anti-coupling projections is small with respect to the thickness d of the tab, it is not necessary to provide the ridges 59.

In Fig. 2, a bottom view (X) and a front view (Y) of the pull tab 5 of the present embodiment are shown. The anti-coupling convex portion 57 of the pull-tab 5 is a distance c between the anti-coupling convex portion 57 and the side surface of the above-described anti-coupling convex portion 57 on the side of the cantilever engaging piece (in FIG. 2, the opposing direction) The distance between the vertices of the connecting protrusions is set to It is smaller than the interval g of the front end of the above-mentioned cantilever locking piece 55. In this manner, it is preferable to set the protrusion for preventing connection to protrude in the middle position of the cantilever locking piece 55, and to reduce the space between the pair of cantilever locking pieces 55. In other words, if the width dimension of the left and right ends of the front end 58 of the pull tab 5 is a, the distance from the side wall on the side of the rotating shaft side of the opening window portion 54 to the side wall on the side of the rotating shaft side of the anti-joining convex portion 57 is b, When the distance between the apexes of the opposing anti-connection convex portions is c, and the thickness of the pull tab 5 (the ridge portion 59 is also added when the ridge portion 59 is present) is set to d, the connection is effectively prevented. From the viewpoint, it is preferable that a>b and d>c. Further, the "width dimension a" of the left and right ends of the pull-tab 5 means that the thickness of the cantilever engaging piece 55 is retracted from the foremost end of the pull-tab 5 to the side of the rotating shaft toward the pull-tab 5 (i.e., the cantilever card) The longest dimension among the width dimensions of the tab 5 in the range of the tab 5 in the range of the length of the tab 5 in the front and back directions of the tab 55.

Further, when the length from the base end of the cantilever locking piece 55 to the side of the rotating shaft is e, the side wall of the opening end portion of the opening window portion 54 to the side wall on the rotating shaft side of the connection preventing convex portion 57 is formed. When the distance is set to f, it is preferable that 1/2e>f is obtained from the viewpoint of securing a sufficient area in which the cantilever locking piece 55 and the pull-tab releasing portion 36 are engaged.

In Fig. 7, a bottom view (X') and a front view (Y') of the pull tab 5 according to another embodiment of the present invention are shown. In the present embodiment, the anti-connection convex portion 57 is provided only in the single cantilever locking piece 55. However, in the present embodiment, the anti-connection convex portion 57 of the tab 5 is set as the anti-coupling convex portion 57 and the cantilever engagement against the anti-coupling convex portion 57 in the same manner as in the above-described embodiment. The distance c of the side of the sheet side is smaller than the interval g of the front end of the cantilever engaging piece 55. also, In the present embodiment, the ridge portion 59 is not present. However, similarly to the previous embodiment, when the thickness of the tab 5 is d, d>c is satisfied.
