Description

Fastener slider

[0001] The present invention relates to a fastener slider used for a slide fastener provided on a seat cover of an automobile seat or the like.

[0002] Conventionally, a slider for a slide fastener (hereinafter abbreviated as a slider) to which a decoration such as an accessory is locked to an upper wing piece is known (see Patent Document 1). A locking body having a horizontal locking piece is provided on the upper wing piece, while a hole having the same shape as the planar shape of the locking body and capable of being fitted into the locking body is provided on the decoration. In addition, the decoration is provided with a pair of protrusions between which the horizontal locking piece is disposed. In order to lock the decoration to the locking body in this slider, the hole of the decoration and the locking body are aligned, the head of the locking body is inserted through the hole, and the decoration is rotated 90 degrees with respect to the locking body. As a result, the horizontal locking piece is caught on the decoration and fits between the pair of protrusions, the rotation of the decoration is stopped, and rattling does not occur, resulting in a stable fitting state. In addition, the decoration having a stable fitting state can be configured to be large with respect to the slider so as to be easily handled as a pull (knob) of the slider.

[0003] Japanese Utility Model Publication No. 62-5008

[0004] For example, a fastener slider used for thin and light clothing such as packable wear or a seat cover and having a body and a pull is preferably configured to be as flat as possible in order to reduce a sense of incongruity and a sense of foreign matter. However, since the body is configured with an annular portion through which the pull is inserted in the left-right direction and is swingably connected, it is difficult to configure the fastener slider to be flatter.

[0005] By the way, in the slider described in Patent Document 1, a decoration that can be used as a pull is locked to the locking body in a form different from the above-described connection form of the pull. However, since the decoration is in a stable fitting state in which the rotation with respect to the locking body is stopped and rattling does not occur, the decoration cannot be swung as a pull, and it is necessary to make the decoration larger than the slider so as to be easily handled as a pull.

[0006] The object of the present invention is to provide a fastener slider that has a swingable pull tab and can be flattened.

[0007] [1] The fastener slider of the present invention comprises a body having an upper wing plate, a lower wing plate, and a column connecting the upper wing plate and the lower wing plate, and a pull tab connected to the upper wing plate, wherein the body is provided with an engaging shaft portion having a shaft portion protruding from the upper wing plate and a head portion bulging in a direction perpendicular to the axial direction of the shaft portion, and the pull tab is provided with an engaging hole portion having an insertion / removal position in which the head portion can be inserted and removed and an engagement position in the perpendicular direction different from the insertion / removal position in which the head portion engages with the engaging shaft portion in a way that prevents insertion and removal, and the pull tab is rotatably connected to the body in an engaged state in which the engaging shaft portion is positioned at the engagement position of the engaging hole portion.

[0008] [2] In the fastener slider of the present invention, the pull tab has a gripping portion that is spaced apart from the engagement hole, and the insertion / removal position may be located closer to the gripping portion than the engagement position.

[0009] [3] In the fastener slider of the present invention, the body and the pull tab may be made of resin.

[0010] [4] The pull tab may be made of soft material, and the body may be made of hard material.

[0011] [5] In the fastener slider of the present invention, a positioning projection is formed on one of the body and the pull tab, projecting toward the other body and the pull tab, and a positioning hole is formed on the other body and the pull tab into which the positioning projection is releasably fitted.

[0012] [6] In the fastener slider of the present invention, the positioning projection may have a curved surface at least around it.

[0013] [7] In the fastener slider of the present invention, the thickness dimension of at least the engagement hole portion of the pull tab may be smaller than the axial dimension between the head portion of the engagement shaft portion and the upper wing plate. [8] In the fastener slider of the present invention, the insertion / removal position may be located at an intermediate position of the engagement hole portion.

[0014] [9] In the fastener slider of the present invention, the periphery of the head of the engaging shaft portion and the periphery of the engaging hole portion extend in the orthogonal direction and have the same shape as each other, and the engaging hole portion may be positioned at different angles with respect to the head portion around the axial direction when the pull handle is positioned to be pulled.

[0015]

[10] In the fastener slider of the present invention, the pull tab is configured to be elastically deformable, and the engagement hole has a second hole positioned in the insertion / removal position and into which the head of the engagement shaft can be inserted and removed, and a first hole that is continuous with the second hole and positioned in the engagement position and engages with the portion of the engagement shaft between the head and the upper wing plate, and the width dimension of the continuous portion of the first hole and the second hole may be smaller than the diameter dimension of the portion of the engagement shaft between the head and the upper wing plate.

[0016] According to the present invention, it is possible to provide a fastener slider that has a swingable pull tab and can be made flat.

[0018] [First Embodiment] Hereinafter, a first embodiment of the present invention will be described based on the drawings. In Figures 1 to 8, the fastener slider 1 (hereinafter abbreviated as "slider 1") according to the first embodiment is used in a slide fastener (not shown) provided on thin, lightweight clothing or seat covers, and engages or disengages the rows of elements of the slide fastener by sliding movement, and comprises a body 2 through which the rows of elements can be inserted, and a pull tab 3 connected to the body 2. In the following description, for convenience of explanation, the sliding direction of the slider 1 will be defined as the X-axis direction, the width direction (left-right direction) of the slider 1 will be defined as the Y-axis direction, and the thickness direction (up-down direction, the axis direction of the engagement shaft portion 25 described later) of the slider 1 will be defined as the Z-axis direction. The X, Y, and Z axis directions are orthogonal to each other. The rotation direction of the pull tab 3 will be defined as the R direction.

[0019] The fuselage 2 is made of synthetic resin and has an upper wing plate 21 and a lower wing plate 22 facing each other in the Z-axis direction, and a column 23 connecting the upper wing plate 21 and the lower wing plate 22. An insertion opening 24 is formed between the upper wing plate 21 and the lower wing plate 22 through which the aforementioned element rows are inserted. One opening of the insertion opening 24 is a so-called shoulder opening 241, and the other opening of the insertion opening 24 is a so-called rear opening 242, with the column 23 positioned closer to the shoulder opening 241 than to the rear opening 242. The fuselage 2 is configured such that the element rows interlock with each other when sliding to one side in the X-axis direction, while the column 23 disengages the elements when sliding to the other side in the X-axis direction.

[0020] The upper wing plate 21 is provided with an engagement shaft portion 25 that engages with an engagement hole portion 35 of the pull handle 3 (described later), and a positioning projection portion 29 that protrudes in the Z-axis direction from the surface (upper surface) of the upper wing plate 21 at a position spaced apart in the X-axis direction from the engagement shaft portion 25. The engagement shaft portion 25 is located closer to the shoulder 241, and the positioning projection portion 29 is located closer to the rear opening 242. The surface of the upper wing plate 21 is flat except for the portions where the engagement shaft portion 25 and the positioning projection portion 29 are provided.

[0021] The engaging shaft portion 25 has a shaft portion 251 that protrudes in the Z-axis direction from the surface of the upper wing plate 21, and a head portion 252 that bulges out on both sides in the Y-axis direction at the tip of the shaft portion 251.

[0022] The shaft portion 251 is formed in a roughly cylindrical shape and forms an annular recess between the head portion 252 and the upper wing plate 21.

[0023] As mentioned above, the head portion 252 bulges in the Y-axis direction, while its central portion is recessed on both sides in the X-axis direction. The center of the head portion 252 is located on the axis O along the Z-axis direction of the shaft portion 251. Furthermore, even in its central portion, the head portion 252 protrudes slightly more than the shaft portion 251 in the X-axis direction.

[0024] In the first embodiment, the positioning projection 29 is formed in a horizontally elongated block shape in the Y-axis direction. The upper part of the surface of the positioning projection 29 on the rear opening 242 side protrudes slightly toward the rear opening 242 side in the X-axis direction, so that the positioning hole 39 of the pull handle 3, which will be described later, can be attached to it.

[0025] The pull handle 3 is made of the same synthetic resin material as the fuselage 2, is flexible, thin, and elliptical in shape, and has a gripping portion 31 on one end 301. The gripping portion 31 is provided with a hole 32 extending in the Y-axis direction. The other end 302 of the pull handle 3 is provided with an engagement hole 35, which is spaced apart from the gripping portion 31 and engages with the engagement shaft portion 25, and a positioning hole 39 is provided between the engagement shaft portion 25 and the hole 32, which fits with a positioning projection 29. The overall thickness dimension of the pull handle 3 in the Z-axis direction is smaller than the dimension in the Z-axis direction between the head 252 of the engagement shaft portion 25 and the upper wing plate 21. Therefore, the thickness dimension of at least the area around the engagement hole 35 of the pull handle 3 is smaller than the dimension in the Z-axis direction between the head 252 of the engagement shaft 25 and the upper wing plate 21. As a result, the pull handle 3 can smoothly rotate (swivel) 360 degrees around the axis O of the engagement shaft 25 when the engagement shaft 25 and the engagement hole 35 are engaged. Furthermore, when the lower surface of the other end 302 of the pull handle 3 is in contact with the upper surface of the upper wing plate 21, the upper surface of the other end 302 of the pull handle 3 is in a non-contact state with respect to the head 252, separated by a distance in the Z-axis direction. Therefore, the pull handle 3 can lift the gripping portion 31 to some extent in the Z-axis direction, thereby making the pull handle 3 easier to pull.

[0026] The engagement hole portion 35 has a shape complementary to the head portion 252 of the engagement shaft portion 25, and the periphery of the head portion 252 and the periphery of the engagement hole portion 35 have the same shape. Furthermore, the engagement hole portion 35 extends in a direction perpendicular to the Z-axis direction, in the direction in which one end 301 and the other end 302 of the pull handle 3 face each other. When the slider 1 is pulled to slide it to one side in the X-axis direction, the engagement hole portion 35 is arranged as shown in Figure 8, and when the slider 1 is pulled to slide it to the other side in the X-axis direction, it is arranged as shown in Figure 7. In the pull handle 3 arranged for pulling, the engagement hole portion 35 is arranged to extend in the X-axis direction and is in a positional relationship of 90 degrees with respect to the engagement shaft portion 25 which bulges in the Y-axis direction. That is, when the pull handle 3 is positioned for pulling, the engagement hole portion 35 is arranged at different angles around the Z-axis direction with respect to the head portion 252.

[0027] The engagement hole 35 has an insertion / removal position P1 into which the head 252 can be inserted and removed, and an engagement position P2 which is at a different position from the insertion / removal position P1 in the orthogonal direction (the X-axis direction in the arrangement shown in Figures 7 and 8), and is spaced apart from the insertion / removal position P1 toward the other end 302 of the pull handle 3. The insertion / removal position P1 is located closer to the gripping portion 31 than the engagement position P2, and is positioned at an intermediate position in the X-axis direction of the engagement hole 35 in the state shown in Figures 7 and 8. Note that the width dimension in the Y-axis direction of the engagement hole 35 at the insertion / removal position P1 in the state shown in Figures 7 and 8 is smaller than the width dimension at the engagement position P2.

[0028] The positioning hole 39 is formed as a substantially rectangular hole located at the position where the positioning projection 29 is positioned as shown in Figure 7, and it penetrates in the Z-axis direction. The pull handle 3 maintains its position to some extent when the positioning projection 29 fits into the positioning hole 39 at the position shown in Figure 7. Furthermore, by rotating the pull handle 3 in the R direction at the position shown in Figure 7, the fitting of the positioning projection 29 and the positioning hole 39 is released, and the pull handle 3 becomes swingable in the R direction. Note that although the positioning hole 39 is formed as a through hole, it may also be bottomed.

[0029] In the slider 1 described above, the pull handle 3 is connected to the body 2 so as to be rotatable (swingable) in the R direction, with the engaging shaft portion 25 positioned at the engaging position P2 of the engaging hole portion 35.

[0030] [Procedure for connecting the pull handle 3 to the body 2] The procedure for connecting the pull handle 3 to the body 2 will be described below. First, as shown in Figures 5 and 6, the pull handle 3 is positioned relative to the body 2 in a direction such that the shape of the engagement hole 35 matches the shape of the head 252 of the engagement shaft 25. Here, the longitudinal direction of the pull handle 3 is aligned with the Y-axis direction. Also, the axis O of the engagement shaft 25 is positioned at the insertion / removal position P1 of the engagement hole 35.

[0031] Next, the head portion 252 of the engaging shaft portion 25 is inserted into the engaging hole portion 35, and the engaging shaft portion 25 is inserted into the engaging hole portion 35 until the shaft portion 251 is positioned opposite the periphery of the engaging hole portion 35. At this time, the shaft portion 251 is positioned in insertion / removal position P1.

[0032] Next, by rotating the pull handle 3 in the R direction around the axis O and pulling the gripping portion 31, the shaft portion 251 is moved from the insertion / removal position P1 to the engagement position P2, so that the shaft portion 251 is positioned at the engagement position P2 as shown in Figure 7. At this time, the bulging portion of the head portion 252 fits over the portion around the engagement hole portion 35, so that the engaging shaft portion 25 is engaged and cannot be removed from the engagement hole portion 35. Also, in the state shown in Figure 7, the positioning projection portion 29 fits into the positioning hole portion 39, so when the pull handle 3 is not being operated, the state shown in Figure 7 is maintained, and this fitting prevents the engaging shaft portion 25 from unexpectedly moving from the engagement position P2 to the insertion / removal position P1. In this way, the pull handle 3 is connected to the fuselage 2 by engaging the engagement hole portion 35 of the pull handle 3 with the engaging shaft portion 25 provided on the upper wing plate 21.

[0033] In the connected state of the pull handle 3 and the body 2, the pull handle 3 is rotatable in the R direction around the shaft portion 251, as shown in Figures 6 to 8. Furthermore, since the pull handle 3 is operated by pulling, it is not possible to remove the pull handle 3 from the body 2 unless intentionally, by positioning the shaft portion 251 at the insertion / removal position P1 and aligning the pull handle 3 with the body 2 in a predetermined orientation (sideways in this embodiment) so that the head portion 252 and the engagement hole portion 35 are aligned. In addition, since the pull handle 3 is flexible, it can be swung slightly in the Z-axis direction to facilitate operation, and when the pull handle 3 is pulled, the engagement hole portion 35 is pressed against the shaft portion 251 by elastic deformation, making it easy to rotate and pull the pull handle 3 and allowing for stable pulling operations.

[0034] According to the slider 1 described above, the entire structure is made of synthetic resin, making it easy to reduce weight, and the two-part design allows for a simple configuration. The pull handle 3 can be easily and freely connected to the body 2 in a predetermined orientation (sideways), and in the connected state, the pull handle 3 is less likely to detach from the body 2 accidentally. Furthermore, by intentionally positioning the shaft portion 251 in the insertion / removal position and aligning the pull handle 3 in a predetermined orientation (sideways), the pull handle 3 can be easily removed from the body, making it easy to replace the pull handle 3.

[0035] In the first embodiment, the positioning projection 29 is formed in a horizontally elongated block shape in the Y-axis direction, as shown in Figure 3, for example, but is not limited to this shape. For example, as shown in the modified example in Figure 9, a positioning projection 290 may be provided that protrudes from the surface of the upper wing plate 21 and has a curved surface 291 at least around its periphery. The positioning projection 290 shown in Figure 9 is formed horizontally elongated in the Y-axis direction and is formed in a substantially elliptical shape in plan view. By forming the aforementioned curved surface 291 on the positioning projection 290 in this way, the fitting and unfitting of the positioning projection 290 and the positioning hole 39 can be performed more smoothly when the pull handle 3 is rotated.

[0036] [Second Embodiment] A second embodiment of the present invention will be described below with reference to the drawings. In Figures 10 to 15, the fastener slider 1B according to the second embodiment (hereinafter abbreviated as "slider 1B") is used in a slide fastener provided on a seat cover of an automobile seat, similar to the first embodiment, and engages or disengages the rows of elements of the slide fastener by sliding movement, and comprises a body 2 through which the rows of elements can be inserted and a pull handle 5 connected to the body 2. For the sake of explanation, the X, Y, Z axis directions, R direction and axis O are also substantially the same as in the first embodiment. In Figures 10 to 15, the body 2 is configured substantially the same as in the first embodiment except for the shape of the head 452 of the engaging shaft portion 45, so only the upper wing plate 21 on which the engaging shaft portion 45 is provided is shown, and the lower wing plate 22 and column 23 are not shown. In addition, the body 2 and pull handle 5 are not provided with positioning projections 29 or positioning holes 39, but they may be provided.

[0037] The upper wing plate 21 is provided with an engagement shaft portion 45 that protrudes from its surface in the Z-axis direction. The engagement shaft portion 45 has a cylindrical shaft portion 451 and a head portion 452 that bulges outward from the shaft portion 451 at its tip.

[0038] The pull tab 5 is made of synthetic resin and is formed in a thin plate shape that is flexible and elastically deformable. The pull tab 5 is provided with a gripping portion 51 with a hole formed on one end 501, and an engagement hole portion 55 is provided on the other end 502 side of the gripping portion 51.

[0039] The engagement hole portion 55 is formed in a generally gourd shape, having a first circular hole portion 56 and a second circular hole portion 57 that are continuous with each other. The first hole portion 56 is positioned further away from the gripping portion 51 than the second hole portion 57. The engagement position P2 is located in the first hole portion 56, and the insertion / removal position P1 is located in the second hole portion 57. The width dimension of the first hole portion 56, in this case the diameter dimension, is smaller than the diameter dimension of the head portion 452 of the engagement shaft portion 45, and is equal to or slightly larger than the diameter dimension of the shaft portion 451 of the engagement shaft portion 45. On the other hand, the width dimension of the second hole portion 57, in this case the diameter dimension, is larger than the diameter dimension of the head portion 452. For this reason, the first hole portion 56 has a smaller diameter dimension than the second hole portion 57.

[0040] The continuous portion 58 of the first hole 56 and the second hole 57 is positioned at an intermediate position in the X-axis direction in the state shown in Figure 10, and the width dimension in the Y-axis direction of the continuous portion 58 is smaller than the diameter dimension of the shaft portion 451, which is the portion of the engaging shaft portion 45 between the head 452 and the upper wing plate 21. For this reason, the width dimension in the Y-axis direction of the continuous portion 58 is smaller than the diameter dimensions of the first hole 56 and the second hole 57.

[0041] Furthermore, the overall thickness dimension of the pull handle 5 in the Z-axis direction is smaller than the dimension in the Z-axis direction between the head 452 of the engaging shaft portion 45 and the upper wing plate 21. Therefore, the thickness dimension of the pull handle 5, at least around the engaging hole portion 55, is smaller than the dimension in the Z-axis direction between the head 452 of the engaging shaft portion 45 and the upper wing plate 21. As a result, the pull handle 5 can smoothly rotate (swivel) 360 degrees around the axis O of the engaging shaft portion 45 when the engaging shaft portion 45 and the engaging hole portion 55 are engaged. In addition, when the lower surface of the other end 502 of the pull handle 5 is in contact with the upper surface of the upper wing plate 21, the upper surface of the other end 502 of the pull handle 5 is in a non-contact state with respect to the head 452, separated by a Z-axis distance. Therefore, the pull handle 5 can slightly lift the gripping portion 31 in the Z-axis direction, thereby making the pull handle 5 easier to pull.

[0042] In the above-described slider 1B, the handle 5 is connected to the body 2 as follows. First, as shown in FIG. 14, by arranging the handle 5 with respect to the body 2, the engagement shaft portion 45 is aligned with the insertion / extraction position P1, and then the engagement shaft portion 45 is inserted through the second hole portion 57. Next, the handle 5 is pulled, and while elastically deforming the continuous portion 58, the shaft portion 451 is arranged in the first hole portion 56 as shown in FIG. 15, thereby arranging the shaft portion 451 at the engagement position P2. As a result, the head portion 452 is caught around the engagement hole portion 55, so that the engagement shaft portion 45 and the engagement hole portion 55 are in an engaged state, and the handle 5 is connected to the body 2. In this connected state, the handle 5 can rotate 360 degrees in the R direction. Also, the continuous portion 58 has a smaller diameter than the shaft portion 451, and when the handle 5 is pulled, the continuous portion 58 narrows in the Y-axis direction due to elastic deformation, so that the possibility of the shaft portion 451 being unexpectedly arranged at the insertion / extraction position P1 can be suppressed, and the connected state between the handle 5 and the body 2 can be preferably maintained.

[0043] When removing the handle 5 from the body 2 for replacement or the like, the gripping portion 51 is pushed into the engagement shaft portion side to arrange the shaft portion 451 at the insertion / extraction position P1, and the engagement shaft portion 45 is extracted from the second hole portion 57.

[0044] [Modification] In the first and second embodiments, the body 2 and the handles 3 and 5 are made of synthetic resin, but the present invention is not limited thereto, and they may be made of metal or the like. Also, the handles 3 and 5 are soft, and the body 2 is hard, but the body 2 and the handles 3 and 5 may be made of the same material and configured homogeneously.

[0045] In the first embodiment and its modification, the positioning protrusions 29 and 290 are provided on the upper wing plate 21, and the positioning hole portion 39 is provided on the handle 3, but the present invention is not limited thereto, and the positioning protrusions 29 and 290 may be provided on the handle 3, and the positioning hole portion 39 may be provided on the upper wing plate 21. Also, in the first embodiment, the positioning protrusion 29 and the positioning hole portion 39 are provided, but the present invention is not limited thereto, and the configuration of the positioning protrusion 29 and the positioning hole portion 39 may be omitted.

[0046] In the first and second embodiments, the thickness dimension in the Z-axis direction around at least the engagement holes 35 and 55 of the pull handles 3 and 5 is smaller than the dimension in the Z-axis direction between the heads 252 and 452 of the engagement shafts 25 and 45 and the upper wing plate 21. However, if the pull handles 3 and 5 are rotatable in the R direction, the thickness dimension in the Z-axis direction around the engagement holes 35 and 55 of the pull handles 3 and 5 may be the same as the dimension in the Z-axis direction between the heads 252 and 452 of the engagement shafts 25 and 45 and the upper wing plate 21.

[0047] [Summary of Embodiments] (1) The fastener sliders 1 and 1B of the first and second embodiments include a body 2 having an upper wing plate 21, a lower wing plate 22 and a column 23 connecting the upper wing plate 21 and the lower wing plate 22, and a pull tab 3 and 5 connected to the upper wing plate 21, wherein the body 2 has an engaging shaft portion 25 having shaft portions 251 and 451 protruding from the upper wing plate 21 and head portions 252 and 452 bulging in a direction perpendicular to the axial direction of the shaft portions 251 and 451, A 45 is provided, and the pull tabs 3 and 5 are provided with engagement holes 35 and 55 having an insertion / removal position P1 in which the heads 252 and 452 can be inserted and removed, and an engagement position P2 in a position different from the insertion / removal position P1 in the orthogonal direction in which the heads 252 engage with the engagement shafts 25 and 45 in a way that prevents insertion and removal. The pull tabs 3 and 5 are rotatably connected to the body 2 in an engaged state in which the engagement shafts 25 and 45 are positioned at the engagement position P2 of the engagement holes 35 and 55. According to the fastener sliders 1 and 1B of the first and second embodiments, at the insertion / removal position P1, the heads 252 and 452 of the engagement shafts 25 and 45 can be inserted and removed from the engagement holes 35 and 55, so that the pull tabs 3 and 5 can be attached to and removed from the body 2. Furthermore, at the engagement position P2, the heads 252 and 452 of the engagement shafts 25 and 45 are engaged with the engagement holes 35 and 55 in a way that prevents insertion and removal. Since the engagement shafts 25 and 45 are positioned at the engagement position P2, which is a different position from the insertion / removal position P1 in the orthogonal direction, even if the pull tabs 3 and 5 rotate (oscillate) 360 degrees relative to the body 2, the engagement shafts 25 and 45 are not positioned at the insertion / removal position P1. For this reason, even if the pull tabs 3 and 5 rotate in the R direction relative to the body 2, the connection between the pull tabs 3 and 5 and the body 2 is maintained. Moreover, by using the engagement structure of the engagement shafts 25 and 45 and the engagement holes 35 and 55 described above, the fastener sliders 1 and 1B can be made into a simple two-part structure, and it is not necessary to configure an annular portion in the body 2 through which the pull tabs 3 and 5 are inserted and pivotably connected in the left-right direction. This reduces the portion protruding from the body 2, allowing for a flatter fastener slider 1 and 1B.

[0048] (2) In the fastener sliders 1 and 1B of the first and second embodiments, the pull tabs 3 and 5 have gripping portions 31 and 51 that are arranged at intervals with respect to the engaging hole portions 35 and 55, and the insertion / removal position P1 is arranged closer to the gripping portions 31 and 51 than the engaging position P2. According to such a configuration, when operating the fastener sliders 1 and 1B, the pull tabs 3 and 5 are gripped at the gripping portions 31 and 51 and pulled. Since the insertion / removal position P1 is arranged closer to the gripping portions 31 and 51 than the engaging position P2, the engaging shaft portions 25 and 45 are not unexpectedly arranged at the insertion / removal position P1 particularly when the pull tabs 3 and 5 are pulled, and the connection state between the pull tabs 3 and 5 and the body 2 can be preferably maintained even when the pull tabs 3 and 5 are pulled.

[0049] (3) In the fastener sliders 1 and 1B of the first and second embodiments, the body 2 and the pull tabs 3 and 5 are made of resin. According to such a configuration, for example, they can be formed to be lighter than when the body 2 and the pull tabs 3 and 5 are made of metal.

[0050] (4) In the fastener sliders 1 and 1B of the first and second embodiments, the pull tabs 3 and 5 are soft and the body 2 is hard. According to such a configuration, since the pull tabs 3 and 5 are elastically deformed somewhat, the pull tabs 3 and 5 can be configured to be easy to operate and difficult to break. Also, since the pull tabs 3 and 5 are elastically deformed during the pulling operation and come into close contact with the engaging shaft portions 25 and 45, the pull tabs 3 and 5 can be configured to be difficult to come off the body 2. On the other hand, since the body 2 is hard, it can be smoothly slid along the element row of the slide fastener more than when it is soft.

[0051] (5) In the fastener slider 1 of the first embodiment, a positioning projection 29 (positioning projection 290 in a modified example) is formed on one of the body 2 and the pull tab 3, projecting toward the other body 2 and the pull tab 3, and a positioning hole 39 is formed on the other body 2 and the pull tab 3, into which the positioning projection 29 is releasably fitted. With this configuration, by fitting the positioning projections 29 and 290 into the positioning hole 39, the pull tab 3 connected to the body 2 can be fixed in a predetermined position, while by releasing the fitting, the pull tab 3 can be rotated around the axial direction, and by rotating it as appropriate and pulling the pull tab 3, the body 2 can be easily moved back and forth in the sliding direction. Note that if the fastener slider 1B of the second embodiment is formed with positioning projections 29 and 290 and a positioning hole 39, the same effects as described above will be achieved.

[0052] (6) In modified versions of the fastener sliders 1 and 1B of the first and second embodiments, the positioning projection 290 has a curved surface 291 at least around it. With this configuration, the fitting and unfitting of the positioning projection 290 and the positioning hole 39 can be performed more smoothly, and the rotational operability of the pull tabs 3 and 5 can be improved.

[0053] (7) In the fastener sliders 1 and 1B of the first and second embodiments, the thickness dimension of at least the engagement holes 35 and 55 of the pull tabs 3 and 5 is smaller than the axial dimension between the heads 252 and 452 of the engagement shafts 25 and 45 and the upper wing plate 21. With this configuration, rotation and some tilting intersecting the R direction of the pull tabs 3 and 5 can be permitted when the pull tabs 3 and 5 are connected to the fuselage 2, and the pull tabs 3 and 5 can swing smoothly.

[0054] (8) In the fastener slider 1 of the first embodiment, the insertion / removal position P1 is located at an intermediate position in the engagement hole 35. With this configuration, the risk of the engagement shaft 25 being positioned at the insertion / removal position P1 of the engagement hole 35 of the pull tab 3 when it is pulled is reduced. When removing the pull tab 3 from the body 2, the engagement shaft 25 is intentionally aligned with the insertion / removal position P1.

[0055] (9) In the fastener slider 1 of the first embodiment, the periphery of the head 252 of the engaging shaft portion 25 and the periphery of the engaging hole portion 35 extend in the orthogonal direction and have the same shape as each other, and the engaging hole portion 35 is positioned at different angles around the axial direction with respect to the head 252 when the pull tab 3 is positioned to be pulled. With this configuration, the engaging shaft portion 25 can be inserted into and removed from the engaging hole portion 35 by positioning the pull tab 3 in a predetermined direction relative to the body 2, while the head 252 of the engaging shaft portion 25 can be hooked around the engaging hole portion 35 by positioning the pull tab 3 in a pulling direction.

[0056] (10) In the fastener slider 1B of the second embodiment, the pull tab 5 is configured to be elastically deformable, and the engagement hole 55 has a second hole 57 located at the insertion / removal position P1 and into which the head 452 of the engagement shaft 45 can be inserted and removed, and a first hole 56 which is continuous with the second hole 57 and located at the engagement position P2 and engages with the portion of the engagement shaft 45 between the head 452 and the upper wing plate 21, and the width dimension of the continuous portion 58 of the first hole 56 and the second hole 57 is smaller than the diameter dimension of the portion of the engagement shaft 45 between the head 452 and the upper wing plate 21. With this configuration, the pull tab 5 can be elastically deformed so that the engagement shaft 45 inserted through the first hole 56 can be engaged with the first hole 56 through the continuous portion 58 of the first hole 56 and the second hole 57. Furthermore, the width dimension of the continuous portion 58 of the first hole 56 and the second hole 57 becomes smaller than the diameter dimension of the portion of the engaging shaft 45 between the head 452 and the upper wing plate 21 when the pull handle 5 is restored, so that the engaged state between the engaging shaft 45 and the first hole 56 can be maintained favorably.
