Further, when the sliding members 340 and 440 are slidably arranged on the upper blades 321 and 421 as in the sliders 310 and 410 of Patent Document 1 and Patent Document 2, for example, a thick fabric or the like slides. When the members 340 and 440 collide rearward, the cloth or the like presses the sliding members 340 and 440 and slides forward, and slides with the free ends 333 and 433 of the handle holders 330 and 430. There has been a problem that dough or the like is caught between the members 340 and 440.

And as above-mentioned, when cloth | dough etc. enter into the clearance gap between the end surface 333a by the side of the free end part 333,433 of the handle holders 330 and 430 and the sliding members 340 and 440, or the handle holders 330 and 430 If the cloth or the like is caught between the free ends 333 and 433 and the sliding members 340 and 440, the cloth or the like may become an obstacle when the handle 360 or 460 is attached or replaced. There is a problem that the operation of the sliders 310 and 410 is hindered by the cloth or the like. Further, when the slider is provided with an automatic stop mechanism using a stop claw body, there is a problem in that the dough or the like that has entered the gap bites into the stop claw body and hinders the function of the stop claw body.

The present invention has been made in view of the above-described conventional problems, and its specific purpose is to prevent foreign matter such as cloth from entering or biting between the handle holder and the sliding member.

Accordingly, a gap 13 that is bent in a zigzag manner is provided between the sliding member 40 and the free end portion 33 of the pull handle holder 30.

Here, the zigzag-shaped gap 13 is formed to have a step that bends approximately 90 °. For example, in the left-right direction, a step in the up-down direction is formed between the left side and / or right side portion and the center portion. In addition, for example, it may be provided so as to exhibit a substantially V shape in which at least two straight lines intersect at a predetermined angle.

The pull handle 6 of the first embodiment has a flat pull tab main body 6a that can be picked by a finger, and an arcuate mounting shaft 6b that is integrally formed at one end of the pull main body 6a. ing.

Next, a procedure for assembling the slider 10 of the first embodiment will be described.
First, an operation of assembling the sliding member 40 and the coil spring 5 to the slider body 20 is performed. Specifically, the coil spring 5 is inserted into the spring accommodating groove 26b formed in the upper blade 21 of the slider body 20, and then the front end surface 33a of the sliding member 40 is brought into contact with the rear end of the coil spring 5, so that The sliding member 40 is inserted into the sliding guide groove 26 while compressing the coil spring 5.

When the sliding member 40 is inserted into the sliding guide groove 26, the guide protrusion 43 of the sliding member 40 is fitted into the spring accommodating groove 26 b of the upper blade 21 and the guide portion 44 of the sliding member 40 is inserted. Is inserted into the guide groove 26a of the upper blade 21. Then, after the sliding member 40 is inserted into the sliding guide groove 26, the locking piece 27 erected at the rear end portion of the upper blade 21 is pushed and bent in a direction approaching each other to be swaged. 40 is slidably attached to the upper blade 21 while being biased by the coil spring 5.

At this time, since the crimped locking piece 27 serves as a stopper for the sliding member 40, the position of the sliding member 40 that contacts the locking piece 27 slides on the biasing direction side of the sliding member 40. When the sliding member 40 is located at the sliding end on the urging direction side, it is formed between the free end portion 33 of the handle holder 30 and the upper blade 21 by the closing portion 42 of the sliding member 40. The gap (insertion gap) 12 to be made is closed (or narrowed). On the other hand, the sliding end on the opposite side to the urging direction of the sliding member 40 is a position where the closing portion 42 of the sliding member 40 abuts on a portion covered by the sliding guide groove 26 of the upper blade 21. Become.

When the slider 10 of the first embodiment is viewed from the side, the sliding member 40 is biased by the coil spring 5 and is positioned at the sliding end on the biasing direction side. The free end portion 33 of the handle holder 30 is configured to extend to the rear end side of the closing portion 42 of the sliding member 40 located at the sliding end on the biasing direction side (see FIG. 3). ).

Thus, a predetermined gap 14 is formed between the free end portion 33 of the handle holder 30 and the upper blade plate 21 on the rear side of the closing portion 42 of the sliding member 40. By providing this gap 14, as will be described later, when the mounting shaft portion 6b of the handle 6 is pressed against the closing portion 42 of the sliding member 40 in order to slide the sliding member 40 forward, By inserting the attachment shaft portion 6b of the handle 6 into the gap 14, the attachment shaft portion 6b can be easily positioned. For this reason, the attachment shaft part 6b can be reliably pressed against the closing part 42 of the sliding member 40, and the sliding member 40 can be easily slid forward.

Furthermore, in the slider 10 of the first embodiment, a gap 13 is formed between the sliding member 40 and the free end portion 33 of the handle holder 30 so as not to contact each other. At the same time, when the sliding member 40 is positioned at the sliding end on the urging direction side, the convex portion 34 formed on the end surface 33a on the free end portion 33 side of the handle holder 30 is changed to the sliding member 40. It is comprised so that it may insert in the recessed part 45 formed in the upper surface 42a of the closing part 42 of this. Here, when the convex portion 34 of the handle holder 30 is inserted into the concave portion 45 of the sliding member 40, the tip portion of the convex portion 34 is recessed from the upper surface 42 a where the concave portion 45 of the closing portion 42 is formed. Say to enter the bottom side.

Thus, the clearance 13 is formed between the sliding member 40 and the free end portion 33 of the handle holder 30, so that when the sliding member 40 is slid with respect to the upper blade 21, sliding The member 40 can be smoothly slid without being brought into contact with the free end portion 33 of the handle holder 30. For this reason, when the sliding member 40 is slid and the handle 6 is attached and detached, the attaching operation and the removing operation can be performed smoothly.

Further, when the sliding member 40 is positioned at the sliding end on the urging direction side, the convex portion 34 of the handle holder 30 is inserted into the concave portion 45 of the sliding member 40, whereby the sliding member 40.

For this reason, the attachment shaft portion 6 b of the handle 6 can be moved into the accommodation space 11 through the opened insertion gap 12.

Then, after the attachment shaft portion 6b of the handle 6 has moved into the accommodation space 11, the attachment shaft portion 6b is lifted upward to release the pressing of the sliding member 40 by the attachment shaft portion 6b, and the attachment shaft portion 6b has been pushed forward. The sliding member 40 is urged by the coil spring 5 and moves to the sliding end on the urging direction side, and closes the insertion gap 12 between the free end 33 of the handle holder 30 and the upper blade 21. Thus, the slider 10 of the first embodiment in which the attachment shaft portion 6b of the handle 6 is accommodated in the accommodation space 11 and the handle 6 is held by the handle holder 30 can be obtained.

In addition, when removing the handle 6 held by the handle holder 30 of the slider 10, the slide member 40 is pushed forward with a finger or the like, thereby being advanced against the urging force of the coil spring 5. As a result, the insertion gap 12 between the free end 33 of the handle holder 30 and the upper wing plate 21 opens, so that the attachment shaft portion 6b of the handle 6 is extracted from the accommodation space 11 through the insertion gap 12. Thus, the handle 6 can be easily removed.

As described above, according to the slider 10 of the first embodiment, the sliding member 40 is slidably disposed on the upper blade 21 so that the handle 6 can be attached to and detached from the slider body 20. It is configured.

Further, in the slider 10, the gap 13 is provided between the sliding member 40 and the free end portion 33 of the handle holder 30, and the convex portion 34 provided on the end surface 33 a of the handle holder 30 and the sliding member 40.

For this reason, when the sliding member 40 is slid with respect to the upper blade 21, the sliding member 40 can be smoothly slid without being brought into contact with the free end portion 33 of the handle holder 30. The handle 6 can be attached and detached stably.

Moreover, the gap 13 formed between the sliding member 40 and the free end portion 33 of the handle holder 30 is provided on the projecting portion 34 provided on the end surface 33 a of the handle holder 30 and the sliding member 40. Since the concave portion 45 is bent in a zigzag shape in the vertical direction, it is possible to prevent a foreign material such as a thin cloth from entering the gap 13. For this reason, the slider caused by the trouble that has occurred in the conventional slider 10, specifically, the trouble that the foreign matter that has entered the gap 13 becomes an obstacle when the handle 6 is attached or replaced, or the foreign matter that has entered the gap 13. It can prevent the malfunction that operation of 10 is prevented.

In the slider 10 according to the first embodiment described above, the protrusion 34 is provided on the end surface 33a on the free end 33 side of the handle holder 30, and the handle holder 30 is provided on the upper surface of the closing portion 42 of the sliding member 40. By providing the concave portion 45 into which the convex portion 34 can be inserted, foreign matter can be prevented from entering the gap 13 formed between the free end portion 33 of the handle holder 30 and the sliding member 40.

It has a convex portion 146 that is continuously formed upward from the portion 142 and can be inserted into the concave portion 135 of the handle holder 130. In this case, the main body portion 141, the closing portion 142, and the convex portion 146 of the sliding member 140 are integrally formed with the same size in the slider width direction, and the closing portion 142 is formed integrally. In addition, an inclined surface 143 is formed on the rear portion of the convex portion 146 to gradually reduce the dimension in the slider length direction upward.

Furthermore, an insertion hole 144 into which the other end of the coil spring 105 can be inserted is formed in the lower end surface 141a of the main body 141. In the second embodiment, the sliding end on the urging direction side of the sliding member 140 is between the convex portion 146 disposed on the sliding member 140 and the concave portion 135 disposed on the pull handle holder 130. It is set by a positioning means (not shown) at a predetermined position where the gap 113 is formed.

Next, a procedure for assembling the slider 110 according to the second embodiment will be described.
First, in order to attach the sliding member 140 to the slider body 120, the sliding member 140 is inserted into the sliding guide hole 126 formed in the slider body 120 from below, and then the coil spring 105 is inserted into the sliding guide hole 126. Is inserted from below and the other end of the coil spring 105 is inserted into the insertion hole 144 of the sliding member 140.

Next, the retaining piece 127 is brought into contact with one end of the coil spring 105, and the retaining piece 127 is engaged with the engaging groove 128 of the slider body 120 while the coil spring 105 is compressed by the retaining piece 127. Accordingly, the sliding member 140 is attached to the slider body 120 so as to be slidable in the vertical direction in a state where the sliding member 140 is biased upward by the coil spring 105.

At this time, since the sliding member 140 is urged upward by the coil spring 105, the convex portion 146 of the sliding member 140 is inserted into the concave portion 135 of the handle holder 130 as shown in FIGS. At the same time, the insertion gap 112 formed between the free end portion 133 of the handle holder 130 and the upper blade 121 is closed by the closing portion 142 of the sliding member 140.

As shown in the first embodiment, the convex portion 146 of the sliding member 140 does not project a part of the surface, but as a convex portion of the entire lateral surface of the sliding member 140 (the same width as the main body portion 141). The formed convex portion 146 gradually decreases in thickness in the front-rear direction as it goes upward. In this example, the convex portion 146 is also a part of the closing portion 142.
In the embodiment of the present specification, the convex portion describes a portion inserted into the concave portion, and is not limited to a portion protruding only partially from the plane.

Thereafter, in order to attach a handle (not shown) to the slider body 120 to which the sliding member 140 and the coil spring 105 are assembled, the attachment shaft portion of the handle is used as the end surface 133a on the free end 133 side of the handle holder 130 and the upper blade plate. The insertion shaft 112 is inserted into the insertion gap 112 formed between the rear member 121 and the attachment shaft portion, and the closing portion 142 of the sliding member 140 is brought into contact therewith.

Further, by pushing the mounting shaft portion forward, the sliding member 140 is slid downward against the urging force of the coil spring 105 via the inclined surface 143 formed on the closing portion 142 and the convex portion 146. . As a result, the insertion gap 112 that has been closed by the closing portion 142 of the sliding member 140 is opened. Therefore, the handle attachment shaft portion is moved into the accommodating space 111 via the opened insertion gap 112, thereby Can be attached to the handle holder 130.

In the case of the slider 110 according to the second embodiment, it is possible to stably attach and remove the handle by sliding the sliding member 140 in the vertical direction with respect to the slider body 120. Moreover, since the gap 113 formed between the sliding member 140 and the free end 133 of the pull handle holder 130 is bent in a zigzag shape in the vertical direction, foreign matter such as thin cloth enters the gap 113. Since this can be prevented, the same effect as the slider 110 of the first embodiment can be obtained.
