Description

Slide fastener

The present invention includes a pair of opposed fastener stringers, a pair of sliders that are slidable along the longitudinal direction of the pair of fastener stringers, and that open and close the pair of fastener stringers, and a longitudinal length of the pair of fastener stringers. The present invention relates to a slide fastener provided with a slide member provided so as to be slidable along a pair of sliders.

Some conventional slide fasteners include a pair of sliders that are slidable with respect to a pair of opposed fastener stringers. In the case of such a slide fastener, when these two sliders are brought close to each other until they collide, a gap is formed between both sliders. Accordingly, water can pass from the upper side of the slide fastener to the lower side of the slide fastener through this gap.

Therefore, slide fasteners aimed at preventing the passage of water from such gaps have already been developed. In this slide fastener, a slide member named a gap concealing member is provided between these two sliders, and the slide member is provided to be slidable along a longitudinal direction with respect to a pair of fastener stringers (patent) Reference 1). The slide member is composed of an upper plate portion and a lower plate portion that are opposed to each other with an interval in the vertical direction, and a connecting portion that connects the upper plate portion and the lower plate portion. It has a structure in which a cut portion that matches the shape of the end portion of the upper blade plate is provided, and a collar portion projects in the front-rear direction at the upper edge portion of each cut portion of the upper plate portion.

This slide fastener is used in a state where the slide member is sandwiched between both sliders when water is not allowed to pass through. Then, the front and rear flanges of the slide member cover the end of the upper wing plate of the front slider in contact with the slide member and the end of the upper wing plate of the rear slider from the upper side, so that the water can slide. It becomes difficult to pass from the upper side to the lower side.

In addition, if this slide member judges from the drawing (FIG. 3, FIG. 4) in patent document 1, it will be estimated that it was integrally molded.

JP 2006-61378 A

However, in the slide fastener shown in Patent Document 1, the collar portion is provided only on the upper plate portion. That is, the collar portion is not provided on the lower plate portion. Therefore, even if the slider is brought into contact with the lower plate portion of the slide member from the front and rear direction by sandwiching the slide member between the two sliders, the lower portion of the slider is not restrained by the slide member. Therefore, when an external force that deforms the fastener stringer in the vertical direction is applied, the posture of the slider is displaced, and a vertical gap is easily formed between the slider (upper blade plate) and the collar portion. This gap becomes a factor of reducing the watertightness, that is, the sealing performance of the slide fastener.
Incidentally, as described above, even if the cut portion of the slide member has a shape that matches the end shape of the slider, when the slide member is sandwiched between two sliders (when the two sliders are in contact with the slide member) ), A small gap in the front-rear direction is usually formed between each slider and the cut portion of the slide member. Therefore, the buttocks only serve to cover the gap in the front-rear direction from above.
Accordingly, even if the slide member is sandwiched between the two sliders, water may reach the lower side from the upper side of the slide fastener through the gaps in the vertical direction and the front-rear direction formed between the slider and the slide member.

Also, since the slide member is integrally molded, it is difficult to decorate it.

The present invention has been created on the basis of the above situation, and the object thereof is to improve the sealing performance between the slide member and the slider in a state where the slide member is sandwiched between the two sliders, or the seal. It is to improve the decorativeness while maintaining the same level as before.

The slide fastener of the present invention includes a pair of fastener stringers extending in the front-rear direction and opposed to the left and right, and a pair for sliding along the front-rear direction of the pair of fastener stringers and for opening and closing the pair of fastener stringers. And a slide member provided so as to be slidable along the pair of fastener stringers and sandwiched between the pair of sliders.

Further, an example of the slide fastener of the present invention is characterized by the following. The slide member includes an upper plate portion, a lower plate portion, a connecting portion, a shielding piece, and a guide piece. The upper plate portion and the lower plate portion are disposed above and below the opposing side end portions of the pair of fastener stringers. The connecting portion connects the upper plate portion and the lower plate portion between the opposing side end portions. The shielding piece includes a shielding piece placement portion that is placed on the upper plate portion, and a front and rear flange portion that protrudes forward and backward from the upper plate portion from the shielding piece placement portion. These front and rear collars cover the upper blades respectively provided in the pair of sliders from above. The guide piece projects forward and backward from below the lower plate portion and guides the lower wing plate provided in each of the pair of sliders. An accommodation space capable of accommodating the front and rear end portions of the pair of sliders is formed between the upper and lower ends of the front and rear end portions of the shielding piece and the guide piece.

For the upper plate portion, the lower plate portion, and the connecting portion of the slide member, a material capable of sliding is used. On the other hand, the shielding piece and the guide piece may be the same material as the upper plate portion or the like, regardless of the material, or may be a different material.
Moreover, the slide member should just be provided with the upper board part, the lower board part, the connection part, the shielding piece, and the guide piece, and it does not ask | require whether these are integrally molded.
In order to improve the decorativeness of the shielding piece, it is desirable to do the following.
That is, the slide member includes a slide member main body including an upper plate portion, a lower plate portion, a connecting portion, and a guide piece, and an elastic shielding piece having a shield piece mounting portion attached to the slide member main body. And

Further, in order to increase the area where the collar portion covers the upper wing plate and the decorative area of the shielding piece, it is desirable to do as follows.
That is, each of the pair of sliders includes a handle attachment portion that protrudes from the upper surface of the upper blade, and the front and rear flanges each include a recess portion that accommodates the handle attachment portion.

It does not matter whether the upper surface of the guide piece is uneven or not, or whether it is a horizontal surface or the like, but it is desirable to reduce the vertical distance between the upper blade plate of the slider and the shielding piece as follows.
That is, the guide piece is provided with an inclined surface that gradually rises from the front and rear end toward the connecting portion on the upper surface thereof.

It does not matter whether or not there is a gap between the upper and lower blades and the shielding piece in the state in which the slider is housed in the housing space.
In order to eliminate the gap between the upper and lower blades and the upper and lower shielding plates and bring the shielding pieces into contact with the upper blade and deform them, it is desirable to do the following. That is, the shielding piece is an elastic body, and the vertical dimension of the predetermined portion in the front-rear direction of the accommodation space is set to be equal to or smaller than the vertical dimension of the portion corresponding to the predetermined portion of the slider.

In the previous example, the slide member required a guide piece to improve the sealability in the previous example, but in order to improve the decorativeness while maintaining the seal performance to the same level as in the past, it is an example regardless of the presence or absence of the guide piece. There may be.
That is, the slide member includes a slide member main body including an upper plate portion, a lower plate portion, and a connecting portion, and a shielding piece attached to the slide member main body. The shielding piece is an elastic body, and is attached to the upper plate portion in a state of being placed on the upper plate portion, and protrudes forward and backward from the upper plate portion from the shielding piece placement portion and a pair of It is assumed that there are front and rear flanges that cover the upper blades provided in each slider.

In addition, it is desirable that the slide member of the example regardless of the presence or absence of the guide piece is as follows in order to increase the decorative area and the area where the collar portion covers the upper wing plate.
That is, each of the pair of sliders includes a handle attachment portion that protrudes from the upper surface of the upper blade, and the front and rear flanges each include a recess portion that accommodates the handle attachment portion.

According to the slide fastener of the present invention, when the end portion in the front-rear direction of the slider is accommodated in the front-rear end portion between the shielding piece and the guide piece of the slide member, that is, the accommodation space, the accommodation space is formed by the shielding piece and the guide piece. The upward and downward movement of the slider is restricted, and as a result, the sealing performance between the pair of sliders and the slide member is improved.

In addition, if it is a slide member provided with a slide member main body provided with an upper plate portion, a lower plate portion, a connecting portion, and a guide piece, and an elastic shield piece with a shield piece placement portion attached to the slide member main body. Since the molding of the shielding piece can be performed separately from the molding of the slide member main body, it is easy to improve the decorativeness of the shielding piece and thus the slide fastener as compared with the case where the sliding member is produced by one molding.

Further, the pair of sliders protrudes the handle attachment part from the upper surface of the upper blade, and the hook part has a wide area to cover the upper blade if it has a recess to accommodate the handle attachment part. Thus, the sealability between the pair of sliders and the slide member is improved and the decorativeness is easily improved.

Further, if the upper surface of the guide piece is provided with an inclined surface that gradually rises from the front end in the front-rear direction toward the connecting portion, when the end portion in the front-rear direction of the slider is accommodated in the accommodation space, When the slider is approached, the lower blade of the slider is slightly lifted upward by the inclined surface, and the vertical distance between the upper blade of the slider and the shielding piece of the slide member is narrowed. Sealability is improved.

Furthermore, when the vertical dimension of the predetermined part in the front-rear direction of the storage space is equal to or smaller than the vertical dimension of the part corresponding to the predetermined part of the slider in the state of being stored in the storage space, the slider is stored in the storage space. As a result, the shielding piece, which is an elastic body, and the upper wing plate are in close contact with each other, and the sealing performance is improved.

Also, a slide member body with or without a guide piece, that is, a slide member body having an upper plate portion, a lower plate portion, and a connecting portion, and shielding of an elastic body with a shield piece mounting portion attached to the slide member body In the case of a slide fastener provided with a slide member provided with a piece, the shielding piece can be formed separately from the formation of the slide member main body, so that the decorativeness of the shielding piece and thus the slide fastener can be easily improved.

In the illustrated example, the element row 22 is formed by a large number of elements 22a provided at intervals along the front-rear direction at opposite side end portions of each fastener tape 21. It may be formed by a coiled continuous element connected in the direction. The fastener tape 21 may be a tape having no water stop function (for example, a normal fiber fastener tape 21 alone) or a tape having a water stop function (for example, on the fiber fastener tape 21). It may be a multilayer tape having a synthetic resin waterproofing tape bonded thereto.

The slider 3 is made of metal or synthetic resin, and includes a slider body 3a and a handle 3b supported rotatably with respect to the slider body 3a, as shown in FIGS. .

The slider body 3a includes an upper wing plate 31 and a lower wing plate 32 that are opposed to each other with an interval in the vertical direction, a connecting column (not shown) that connects the upper wing plate 31 and the lower wing plate 32, and an upper wing plate. And a handle attaching portion 33 provided at 31. The handle 3b is attached to the handle attachment portion 33. The slider body 3a has an element passage (not shown) extending in the front-rear direction of the slider body 3a. The element passage is formed between the upper blade 31 and the lower blade 32. The element row 22 can pass through the element passage.

Also, at least one of the upper wing plate 31 and the lower wing plate 32 has a flange 34 that protrudes from the left and right end portions thereof toward the opposing plate side. A tape passage 35 that communicates with the element passage and allows the fastener tape 21 to pass therethrough is formed between the protruding end of the flange 34 and the opposing plate.

The handle attachment portion 33 protrudes upward from the upper surface of the upper blade 31. In the illustrated example, the handle attachment portion 33 has a gate shape and is provided at the center in the left-right direction on the upper surface of the upper blade 31. And in the handle attachment part 33, the insertion hole 33a for attaching the handle 3b is penetrated and formed in the left-right direction.

The handle 3b includes a knob portion 36 for picking with a finger and an attachment portion 37 protruding from one end portion of the knob portion 36 in the front-rear direction. The attachment portion 37 is formed in a ring shape. The handle 3b is attached to the handle attachment portion 33 by passing the attachment portion 37 through the insertion hole 33a.

When the user slides the slider 3 in the front-rear direction, the elements 22a of the pair of

fastener stringers

2 and 2 are engaged or separated, and the pair of

fastener stringers

2 and 2 can be closed or opened. The slide member 4 is sandwiched between the pair of

sliders

3 and 3.

As shown in FIGS. 1 to 5, the slide member 4 can be attached to and detached from two separate parts, that is, the slide member main body 5 and the upper surface of the slide member main body 5. And a shielding piece 6 protruding forward and backward. The slide member 4 is formed by integrating two parts, and as upper and

lower plate portions

51 and 52 facing each other with an interval in the vertical direction, the upper plate portion 51 and the lower plate portion. 52, a connecting portion 53 that connects to the upper plate portion 51, a shielding piece 6 that protrudes forward and backward from the upper plate portion 51, and a guide piece 54 that protrudes from the lower plate portion 52 to the front and rear and guides the lower wing plate 32. . The components other than the shielding piece 6 are the components of the slide member main body 5. That is, the slide member main body 5 includes an upper plate portion 51, a lower plate portion 52, a connecting portion 53, and a guide piece 54. The slide member main body 5 is slidable along the pair of

element rows

22 and 22 and is made of metal (for example, zinc is molded by die casting) or synthetic resin (for example, polyacetal resin is injected) like the slider 3. Molded).

The upper plate portion 51 is a plate that can slide along the upper surfaces of the pair of element rows 22, and the shape of the end surface in the front-rear direction coincides with the shape of the end surface (holding surface) of the holding end portion of the upper blade plate 31. There is something to do.

The lower plate portion 52 is a plate that can slide along the lower surfaces of the pair of element rows 22, and the shape of the end surface in the front-rear direction coincides with the shape of the end surface (holding surface) of the holding end portion of the lower blade plate 32. There is something to do.

The connecting portion 53 has a columnar shape, and connects the center portions of the upper plate portion 51 and the lower plate portion 52 in the left-right direction.

At least one of the upper plate portion 51 and the lower plate portion 52 includes a flange 55 that protrudes from the left and right end portions toward the opposite plate side. In the illustrated example, both the upper plate portion 51 and the lower plate portion 52 have flanges 55. Between the projecting ends of the

flanges

55, 55 that are vertically opposed to each other is a tape passage 57 through which the fastener tape 21 passes, which is on the inner side in the left-right direction with respect to the tape passage 57 and between the upper plate portion 51 and the lower plate portion 52. A pair of left and right element passages 56 are provided between the two. The left and right element passages 56 are partitioned by the connecting portion 53 and are in communication with the corresponding left and right tape passages 57. The pair of left and right tape passages 57 and the element passage 56 accommodate opposite side ends of the pair of left and right slide fasteners 1. Accordingly, the upper plate portion 51 and the lower plate portion 52 are arranged above and below the opposite side end portions of the pair of slide fasteners 1, and the connecting portion 53 is arranged between the opposite side end portions. Since the tape passage 57 has a smaller vertical dimension than the element 22a, the slide member 4 is difficult to come off from the

fastener stringers

2 and 2. When the flange 55 is provided only on one of the upper plate portion 51 and the lower plate portion 52, a tape passage 57 is formed between the upper plate portion 51 or the lower plate portion 52 facing the protruding end of the flange 55. .

The guide piece 54 is a plate that protrudes forward and backward from below the lower plate portion 52, and a guide piece attachment portion 54b that covers the lower side of the lower plate portion 52, and a guide piece main body that protrudes forward and backward from the guide piece attachment portion 54b. Part 54a. Further, the guide piece main body portion 54a is provided with a flat surface 54c and an inclined surface 54d in order from the connecting portion 53 side to the front end in the front-rear direction on the upper surface thereof. The inclined surface 54d is a surface that gradually rises from the front end in the front-rear direction toward the connecting portion 53. The slide member 4 is formed by the guide piece 54, the upper plate portion 51, the lower plate portion 52, and the connecting portion 53.

The shielding piece 6 is a plate-like elastic body (for example, a resin plate such as silicon resin or urethane resin), and the shielding piece 6 is detachably attached to the upper surface of the upper plate portion 51. It is preferable that the upper surface of the shielding piece 6 has decoration such as a pattern, a character, and a pattern. That is, the upper surface of the shielding piece 6 is a decorative surface. Further, the upper plate portion 51 and the shielding piece 6 are provided with a locking projection 71 and a locking recess 72 for enabling attachment / detachment as follows.
The locking convex portion 71 is provided on the upper surface of the left and right end portions of the upper plate portion 51. The locking projection 71 is a bent piece having an L-shaped cross section, and includes a first locking projection 71a protruding upward from the upper surface of the upper plate portion 51, and an upper end portion of the first locking projection 71a. And a second locking projection 71b protruding so as to bend inward in the left-right direction.
The locking recess 72 includes a first locking recess 72a that is recessed in a shape corresponding to the first locking protrusion 71a at the center in the front-rear direction at the left and right ends of the shielding piece 6. The locking recess 72 is a second locking that is recessed in a shape corresponding to the second locking projection 71b on the upper surface of the shielding piece 6 and on the inner side in the left-right direction of the first locking recess 72a. A recess 72b is provided.
The shielding piece 6 is attached to the slide member main body 5 by fitting the locking projection 71 and the locking recess 72 into close contact. Since it is an elastic body, the shielding piece 6 is deformed and the locking recess 72 is fitted into the locking projection 71, so that it is easy to attach. In this attached state, the thickness of the shielding piece 6 is basically the locking protrusion 71 (first locking protrusion) so that the upper surface of the shielding piece 6 is flush with the upper surface of the locking protrusion 71. 71a) is the same size as the upward projecting size. However, the thickness of the second locking recess 72 b is smaller than this dimension, and the second locking recess 71 b is sandwiched between the second locking protrusion 71 b and the upper plate portion 51. In this way, the shielding piece 6 is sandwiched between the left and right first locking projections 71a from the left and right directions, and the first locking projection 71a is sandwiched from the front and rear directions, so that the second locking projections 71b and the upper plate It is sandwiched between the vertical direction with the part 51. Accordingly, the shielding piece 6 is constrained so as not to move in the up / down / left / right and front / rear directions relative to the upper plate portion 51.

In addition, in order to improve the mounting state of the shielding piece 6 and the upper plate portion 51, the shielding piece 6 and the upper plate portion 51 are separately formed with an indented portion and a protruding portion that are fitted to each other using the elasticity of the shielding piece 6. Has been. More specifically, a plurality of indentations and protrusions are formed, and the indentations and protrusions of each set are fitted by the elasticity of the shielding piece 6. In the illustrated example, a first protrusion 73a is formed to protrude upward along the front and rear end portions of the upper surface of the upper plate portion 51, and a first indented portion 73b into which the first protrusion 73a is fitted. Is formed in the lower surface of the shielding piece 6. In addition, a second indented portion 74b is formed in a depth reaching the connecting portion 53 at the center in the left-right direction on the upper surface of the upper plate portion 51, and a second protrusion into which the second indented portion 74b is fitted. The part 74a is formed to project downward from the central part in the left-right direction on the lower surface of the shielding piece 6.

The dimension of the shielding piece 6 in the front-rear direction is longer than that of the upper plate portion 51, and therefore the front and rear end portions of the shielding piece 6 attached to the upper plate portion 51 protrude forward and backward from the upper plate portion 51. The protruding portion is a flange 61 as a shielding piece main body that covers the upper side of the sandwiching end portion of the upper blade 31, and the portion that is placed on the upper plate 51 is the shielding piece placement portion 62. The shielding piece mounting portion 62 is provided with the locking recess 72, the first intrusion portion 73b, and the second protrusion 74a. Each brim 61 includes a hollow portion 63 that is recessed toward the center in the front-rear direction at the center in the left-right direction. The recess 63 accommodates one end portion in the front-rear direction of the pull attachment portion 33. More specifically, when the recess 63 accommodates one end of the handle attachment portion 33, the recess 63 faces the bottom surface 63 a facing the handle attachment portion 33 in the front-rear direction, and faces the handle attachment portion 33 in the left-right direction. It has side surfaces 63b and 63b. The distance between the left and right side surfaces 63b and 63b is formed to be equal to or smaller than the left and right widths of the pull handle attachment portion 33.
Further, the left and right side portions of the flange portion 61 (the outer side portion in the left and right direction with respect to the recess portion 63) are provided with a flat surface 61a and an inclined surface 61b in order from the shielding piece placement portion 62 side toward the front and rear end. ing. The inclined surface 61b is a surface that gradually descends from the front-rear direction tip toward the shielding piece placement portion 62 side. Therefore, the thickness of the collar portion 61 is gradually reduced toward the front end in the front-rear direction.
The flat surface 61a of the flange portion 61 has a length of protrusion in the front-rear direction longer than the length of protrusion in the front-rear direction of the flat surface 54c of the guide piece 54. Therefore, the flat surface 61a of the flange portion 61 and the upper surface of the upper blade 31 The close area is widely secured. Note that the front-rear direction tip of the inclined surface 61 b of the flange part 61 is located farther from the coupling part 53 than the front-rear direction tip of the guide piece 54.

The space between the upper and lower ends of the shield piece 6 and the guide piece 54 is a pair of

housing spaces

58 and 58 that house the front and rear ends of the pair of

sliders

3 and 3. The vertical dimension of each accommodation space 58 becomes longer as the distance from the inlet side, that is, the side farther from the connecting portion 53, is longer due to the inclined surface 61 b of the shielding piece 6 and the inclined surface 54 d of the guide piece 54.
The vertical dimension of the accommodating space 58 may be slightly longer than the vertical dimension of the holding end portion of the slider 3 (the distance between the upper surface of the upper blade 31 and the lower surface of the lower blade 32 accommodated in the accommodating space 58). Preferably, the vertical dimension H1 of the predetermined portion of the accommodation space 58 is preferably equal to or smaller than the vertical dimension h1 of the portion corresponding to the predetermined portion at the sandwiching end portion of the slider 3.
If it demonstrates in detail in the example of illustration, the upper surface of the upper blade 31 used as the part corresponding to a predetermined part and the lower surface of the lower blade 32 will be parallel, and will become a predetermined part (back part of the accommodation space 58). The flat surface 61a of the flange 61 and the flat surface 54c of the guide piece main body 54a are also parallel. The distance between the upper surface of the upper blade 31 and the lower surface of the lower blade 32 (the vertical dimension h1 of the portion corresponding to the predetermined portion) is the distance (predetermined) between the flat surface 61a of the flange 61 and the flat surface 54c of the guide piece main body 54a. The length is the same as the vertical dimension H1) of the part.

The slider 3 and the slide member 4 have a slightly larger vertical dimension of the element passage than the vertical dimension of the element row 22 because of the sliding relationship. The slider 3 and the slide member 4 can rattle in the vertical direction by the slightly wider portion, the so-called play portion.

The slide fastener 1 of the first embodiment described so far is used in the following manner.

fastener stringers

2 and 2, the pair of

fastener stringers

2 and 2 does not open and close.
(2) As shown in FIG. 6, the pair of

sliders

3 and 3 are slid to approach the slide member 4.
(3) When the pair of slide fasteners 1 further approaches the slide member 4, before the collision, the sandwiching end portion of the lower blade 32 of the slider 3 contacts the inclined surface 54d of the guide piece 54 of the slide member 4, and thereafter Due to the rigidity of the guide piece 54, the slider 3 moves relatively slightly along the inclined surface 54 d using sliding play, and the distance between the upper surface of the upper blade 31 and the lower surface of the shielding piece 6 is narrow. The front and rear end portions of the upper blade 31 are guided to the inner portion of the accommodation space 58 between the shielding piece 6 and the guide piece 54. Finally, as shown in FIGS. 7 and 8, the pair of slide fasteners 1 sandwich the slide member 4 from the front and the back, so that the front and rear end surfaces of the upper blade 31 and the upper plate 51 come into contact with each other. The front and rear end surfaces of the lower wing plate 32 and the lower plate portion 52 are in contact with each other, and the lower surface of the shielding piece 6 (the flat surface 61 a of the flange portion 61) is in close contact with the upper surface of the upper wing plate 31 due to the elasticity of the shielding piece 6. The flat surface 54c of the guide piece 54 comes into contact with the lower surface of the lower wing plate 32, resulting in a state of high sealing performance. At this time, one end in the front-rear direction of the handle attachment portion 33 is accommodated in the recess 63 of the shielding piece 6. The bottom surface 63 a and the left and right side surfaces 63 b and 63 b of the recess portion 63 are in close contact with the handle attachment portion 33. Thereby, even if an external force for deforming the

fastener stringers

2 and 2 is applied, the slider 3 is prevented from coming out of the accommodation space 58 due to a frictional force generated by the close contact between the side surfaces 63b and 63b and the handle attachment portion 33.

As shown in FIG. 9, the first modification of the slide member 4 used in the slide fastener 1 of the first embodiment of the present invention is that the slide member body 5 includes an upper plate portion 51 and an opposing upper plate portion 51 that are spaced apart in the vertical direction. A lower plate portion 52 and a connecting portion 53 that connects the upper plate portion 51 and the lower plate portion 52 are provided. The shielding piece placement portion 62 of the shielding piece 6 is attached in a state of being placed on the upper plate portion 51 of the slide member body 5. The slide member body 5 and the shielding piece 6 are integrally formed by injection molding, and the shielding piece 6 is attached to the slide member body 5 so as not to be detachable. More specifically, the slide member 4 is produced by performing injection molding twice. In the first injection molding, the slide member body 5 is manufactured. In the second injection molding, by inserting the slide member 4 into the cavity of the mold, a gap corresponding to the shielding piece 6 is formed, and then the resin material for the elastic body is injected, thereby sliding the shielding piece 6 and the slide. A slide member 4 integrated with the member main body 5 is formed.

In addition, the slide member main body 5 includes a joining portion 77 so that the slide member main body 5 and the shielding piece 6 cannot be attached and detached, and the shielding piece 6 includes a joined portion 78 that joins the joining portion 77. In the illustrated example, the slide member main body 5 has a joining portion 77 formed on the upper surface of the upper plate portion 51. The joint portion 77 includes a convex portion 77a that protrudes upward, and a hole 77b that penetrates the convex portion 77a in the front-rear direction. The shielding piece 6 has a joined portion 78 formed on the lower surface of the shielding piece placement portion 62. The joined portion 78 has a concave portion 78a into which the convex portion 77a fits without a gap, and an insertion portion 78b inserted into the hole portion 77b. Thereby, the joining part 77 and the to-be-joined part 78 are fixed closely.

The 2nd modification of the slide member 4 used with the slide fastener 1 of 1st Embodiment of this invention is formed by one component (essentially integral), as shown in FIG. That is, the slide member 4 of the slide fastener 1 of the first embodiment is formed of two parts, that is, the slide member main body 5 and the shielding piece 6, but the second modification of the slide member 4 includes an upper plate portion 51 and The lower plate portion 52, the connecting portion 53, the shielding piece 6, and the guide piece 54 are integrally formed of the same material.

The slide fastener 1 of the present invention is not limited to the above embodiment, and can be appropriately changed without departing from the gist thereof. For example, in a state where the holding end portion of the slider 3 is accommodated in the front-rear direction accommodation space 58 of the slide member 4, the shielding piece 6 of the slide member 4 and the upper wing plate 31 of the slider 3 are not limited to be in close contact with each other. A configuration with a gap may be used. In the case of this configuration, the vertical distance (the vertical dimension H1 of the accommodation space 58) between the flat surface 61a of the shielding piece 6 and the flat surface 54c of the guide piece 54 is between the upper surface of the upper blade plate 31 and the lower surface of the lower blade plate 32. It shall be formed larger than the vertical dimension. Even in this configuration, the slider 3 moves slightly upward by the sliding surface 54d of the guide piece 54, and the vertical gap between the shielding piece 6 and the upper blade 31 is accordingly increased. Since it becomes narrow, the airtightness between the slide member 4 and the slider 3 improves.

Further, the pair of

sliders

3 and 3 is not limited to the same shape, and may have different shapes. In this case, the shapes of the end surfaces in the front-rear direction of the upper plate portion 51 and the lower plate portion 52 of the slide member 4 are respectively What is necessary is just to make it respond | correspond to the shape of the end surface of the clamping end part of the upper wing board 31 and the lower wing board 32 of the slider 3. FIG.

Further, the slide member 4 is not limited to the configuration including the guide piece 54, and may be configured not to include the guide piece 54 as shown in FIG. In this case, the upper blade 31 of the slider 3 is brought into close contact with the shielding piece 6 by a configuration other than the guide piece 54. In this case, the vertical interval H2 of the predetermined portion in the front-rear direction among the vertical intervals between the lower surface of the front and rear end portions of the shielding piece 6 and the upper surface of the lower plate portion 52 is the vertical interval as shown in FIG. The total value h2 of the vertical dimension 31h of the sandwiched slider 3 and the vertical dimension 22h of the fastener stringer 2 (the vertical dimension of the upper wing plate 31 of the slider 3 in the portion corresponding to the predetermined portion when the slide member 4 is sandwiched) The total value h2) of 31h and the vertical dimension 22h of the element 22a is kept below. In the illustrated example, a contact portion 61 d protrudes downward from a lower surface of a predetermined portion of the front and rear end portions of the shielding piece 6, and the contact portion 61 d is brought into close contact with the upper blade 31.

The shielding piece 6 is not limited to being formed by a single plate, but may be formed by separate front and rear plates. In this configuration, the front and rear shielding pieces 6 include the flange 61 and the shielding piece. It becomes a structure provided with the mounting part 62, respectively.

Further, the guide piece 54 is not limited to a configuration integrated with the slide member main body 5 but may be configured to be detachable from the slide member main body 5 like the shielding piece 6. In this configuration, the slide member main body 5 is The upper plate portion 51, the lower plate portion 52, and the connecting portion 53 are configured.
