DESCRIPTION OF EMBODIMENTS

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 30. A skilled person would be able to combine respective embodiments and/or respective features without requiring excess descriptions. Also, a skilled person would appreciate synergistic effects of such combinations. Overlapping descriptions among the exemplary embodiments would be basically omitted. Referenced drawings are mainly for describing inventions, and may possibly be simplified for the sake of convenience of illustration. Individual features may possibly be highlighted by an expression “in some embodiments”. Individual features will be understood as universal feature which is not only effective to disclosed stop members but also effective to undisclosed stop members.

FIG. 1 is a schematic elevational view of a rear end of a slide fastener 1 provided with a stop member 50 according to an aspect of the present disclosure. First and second fastener stringers 31,32 are closed, and illustration of slider 40 (See FIGS. 2 and 3) positioned frontward of the stop member 50 of the slide fastener 1 is omitted. FIG. 2 is a schematic perspective view of a non-limiting exemplary slider 40 included in the slide fastener 1. FIG. 3 is a schematic side view of a non-limiting exemplary slider 40 included in the slide fastener 1.

Slide fastener 1 has first and second fastener stringers 31,32 and a slider 40 for opening and closing the first and second fastener stringers 31,32. The first fastener stringer 31 has a first fastener tape 11 and first fastener elements 21 provided on the side-edge, extending in the lengthwise direction, of the first fastener tape 11. The second fastener stringer 32 has a second fastener tape 12, and second fastener elements 22 provided on a side-edge, extending in the lengthwise direction, of the second fastener tape 12.

Fastener tape 11,12 may be a fabric such as woven fabric or knitted fabric or combination thereof. The fastener tape 11,12 has a pair of tape surfaces which define a thickness of the fastener tape. The fastener element 21,22 may be a resin element, metal element, coil element or other types of element. The side-edge of the first fastener tape 11 with the first fastener element 21 and the side-edge of the second fastener tape 12 with the second fastener element 22 are arranged to face one another, and thus may be referred to as opposed side-edges.

Frontward movement of slider 40 closes the first and second fastener stringers 31,32. Rearward movement of slider 40 opens the first and second fastener stringers 31,32. In the present specification, “Front-and-Rear direction” is determined based on a direction of movement of slider 40. The first and second fastener stringers 31,32 are arranged in Left-and-Right direction that is orthogonal to the Front-and-Rear direction. The first and second fastener stringers 31,32 can be thus referred to as left and right fastener stringers. This holds true for the fastener tapes 11,12 and the fastener elements 21,22.

Left-and-Right direction is a direction orthogonal to the Front-and-Rear direction and parallel to a tape surface of respective fastener tapes 11,12. Up-and-Down direction is orthogonal to Front-and-Rear direction and Left-and-Right direction. Up-and-Down direction matches a direction an interconnecting post 43 (described below) of the slider 40 extends. Redefining the Font-and-Rear direction, Left-and-Right direction, and Up-and-Down direction would be possible based on other descriptions in the present specification.

As shown in FIGS. 2 and 3, the slider 40 has a top wing 41, a bottom wing 42, and an interconnecting post 43 that interconnects the top wing 41 and the bottom wing 42. Paired left and right front mouths 44 are arranged to sandwich the interconnecting post 43. Rear mouth 45 is arranged at the opposite side relative to the front mouth 44 in the front-and-rear direction. Left slit (or tape-passage) 46, allowing the first fastener tape 11 to move there-though, extends between the left-side front mouth 44 and the rear mouth 45. Right slit 46, allowing the second fastener tape 12 to move there-through, extends between the right-side front mouth 44 and the rear mouth 45.

The slider 40 has Y-shaped element-passage bifurcated by the interconnecting post 43 between the top wing 41 and the bottom wing 42. First fastener elements 21 enter in and go out from the slider 40 via the left-side front mouth 44. Second fastener elements 22 enter in and go out from the slider 40 via the right-side front mouth 44. Engaged first and second fastener elements 21,22 enter in and go out from the slider 40 via the rear mouth 45.

Top wing 41 of the slider 40 includes a top wing plate 41a and paired top flanges 41b protruded downward at the left and right side-edges of the top wing plate 41a. Bottom wing 42 includes a bottom wing plate 42a and paired bottom flanges 42b protruded upward at the left and right side-edges of the bottom wing plate 42a. In some cases, one of the top and bottom flanges 41b and 42b is omitted. The top wing plate 41a and the bottom wing plate 42a may be arranged in a plane orthogonal to Up-and-Down direction along which the interconnecting post 43 extends. Optionally, the slider 40 has a pull-attachment column 48 and a pull tab 49 attached to the top wing plate 41a via the pull-attachment column 48. Optionally, the slider 40 has a locking pawl 47 to be operated by the pull tab 49. Note that, the slider 40 may be made of metal, resin or other material.

Slide fastener 1 has a stop member 50 additionally to the above-described first and second fastener stringers 31,32. The stop member 50 defines a stop position for the slider 40. The stop member 50 of the present disclosure has first and second members 51 and 52 which are separable. Separation of the first and second members 51 and 52 allows separation of the first and second fastener stringers 31,32. Therefore, the stop member 50 may be referred to as a separable stop. The first member 51 is secured to the first fastener tape 11 and positioned rearward of the first fastener element 21. The second member 52 is secured to the second fastener tape 12 and positioned rearward of the second fastener element 22. The first or second member 51,52 may be arranged to be slightly protruded rearward from the terminal end 11e, 12e of the first or second fastener tape 11,12, not necessarily limited to this though. The stop member 50 is provided at the terminal of the fastener stringer 31,32 or of the fastener tape 11,12 or of the fastener elements 21,22 and thus may be referred to as a terminal member. Note that, each of the first and second members 51 and 52 may be made of resin, metal or other material.

FIG. 4 is schematic perspective view of the first member 51. FIG. 5 is a schematic perspective view of the first member 51, illustrating a structure of the first member at the opposite side compared with FIG. 4. FIG. 6 is a schematic perspective view of the first member 51 which is viewed obliquely from a different point compared with FIG. 5. FIG. 7 is a schematic perspective view of the second member 52. FIG. 8 is a schematic perspective view of the second member 52, illustrating a structure of the second member 52 at the opposite side compared with FIG. 7. FIG. 9 is a schematic cross-sectional view of the stop member taken along a chain line X9-X9 in FIG. 1.

As would be understood by referring to FIGS. 1 and 4-8, the first member 51 has a first insert 71 to be inserted into the slider 40 via the rear mouth 45 of the slider 40 of the slide fastener 1; and a first base 61 positioned rearward of the first insert 71. The second member 52 includes a second insert 72 to be inserted into the slider 40 via the slit 46 extending between the rear mouth 45 and the front mouth 44 of the slider 40, and a second base 62 to be overlaid onto the first base 61.

As would be well understood from FIG. 9 and the following descriptions, in the present embodiment, the first and second bases 61,62 are configured to effect magnetic attraction and/or repulsion (in the case of FIG. 9, magnetic attraction) between the first and second bases 61,62 when the first and second bases 61,62 are overlaid. The second base 62 rotates relative to the first base 61 in accordance with the magnetic attraction and/or repulsion to allow the second insert 72 to pivot toward the slit 46. Accordingly, the stop member 50 with improved operability can be provided.

The first insert 71 extends along the Front-and-Rear direction between the first base 61 and the first fastener elements 21. The second insert 72 extends along the Front-and-Rear direction between the second base 62 and the second fastener elements 22. The first insert 71 has a groove 73 into which the second insert 72 is inserted. The groove 73 extends in the Front-and-Rear direction and is opening at front, rear and right sides. The groove 73 receives the second insert 72 which has entered into the slider 40 via the right-side slit 46 of the slider 40 while the first insert 71 has been inserted into the slider 40. The second insert 72 is inserted into the groove 73 of the first insert 71 so that upward-and-downward displacement of the second insert 72 is restricted.

The first member 51 may be configured to facilitate to keep the slider 40 stationary on the first member 51. It is facilitated that the second insert 72 can enter into the slider 40 via the right-side slit 46 of the slider 40 while the first insert 71 has been inserted into the slider 40.

Additionally to the first insert 71, the first member 51 may have one or any combination of a thin plate 74, a guide 75, and a stopping wall 76. Thin plate 74 is arranged adjacent to the first insert 71 in the left-and-right direction. Thin plate 74 has a thickness that enables its insertion into the slit 46 of the slider 40. Guide 75 is projected from the thin plate 74 in Up-and-Down direction and extends along the Front-and-Rear direction. Embodiments are envisioned where the guide 75 is protruded from the thin plate 74 upward only or downward only. Groove 77 is formed between the first insert 71 and the guide 75, and a flange portion of the slider 40 is inserted into the groove 77. Note that likewise the guide 75, the first insert 71 is protruded from the thin plate 74 in Up-and-down direction. The stopping wall 76 extends in Left-and-Right direction and is coupled to the first insert 71, the thin plate 74, and the guide 75. The stopping wall 76 defines a stop position for the slider 40.

The first base 61 is positioned rearward of the first insert 71, and is directly or indirectly coupled to the first insert 71. Indirect coupling of the first base 61 with the first insert 71 indicates that the first base 61 is coupled with the first insert 71 via another or other structural portion(s) such as the stopping wall 76. The first base 61 has a flat plate 63, an axial portion 81, and a sloped surface 83. The axial portion 81 is arranged in and protruded downward from the bottom surface the flat plate 63. The axial portion 81 has a portion with a diameter reduced toward the end 91. The axial portion 81 has an end surface 81a in its end 91, and an outer peripheral surface 81b in the outer periphery of the end surface 81a. Flattened end surface 81a reduces a stimulus otherwise given to a human skin by the axial portion 81. The sloped surface 83 extends about a rotational axis AX regarding the pivoting of the second insert 72. The sloped surface 83 extends in an arc about the rotational axis AX, but embodiments are envisioned where it extends across the entire circle about the rotational axis AX. The sloped surface 83 extends between the outer peripheral surface 81b of the axial portion 81 and the bottom surface of the flat plate 63. Particularly, in some cases, the sloped surface 83 is arranged to convert displacement of the second base 62 in the axial direction of the rotational axis AX to displacement of the second base 62 about the rotational axis AX.

The second insert 72 of the second member 52 includes a portion which is capable of entering into the slider 40 via the slit 46 of the slider 40. For example, the second insert 72 is a flat plate with a thickness enabling the passing via the slit 46 of the slider 40. The second insert 72 has a side-edge 72a that touches the top wing 41 or the bottom wing 42 of the slider 40. The side-edge 72a of the second insert 72 has a shape that matches a side part of the profile of the top or bottom wing 41 or 42 of the slider 40. The side-edge 72a of the second insert 72 has a recess 72b for avoiding interference with a corner 42c of the slider 40.

The second member 52 has a guide 85 and a third fastener element 23 additionally to the second insert 72. The guide 85 is protruded in both sides of upward and downward from the second insert 72, and extends in the Front-and-Rear direction. This guide 85 defines a passage for the slider 40. The third fastener element 23 is coupled to the front end of the second insert 72 and is positioned between the second insert 72 and the second fastener element 22. When the second insert 72 is inserted into the slider 40 via the slit 46 which extends between the rear mouth 45 and the front mouth 44 of the slider 40, the third fastener element 23 is positioned adjacent to and frontward of the front mouth 44 of the slider 40. Frontward movement of the slider 40 allows the third fastener element 23 to be inside the slider 40 and, in turn, be engaged with the first fastener element 21 inside the slider 40 (See FIG. 1).

The third fastener element 23 has a groove 24 and the first insert 71 has an insertion portion 25. The insertion portion 25 of the first insert 71 is inserted into the groove 24 of the third fastener element 23 (see FIG. 1), thus suppressing the front ends of the first and second members 5152 from being separated in Up-and-Down direction.

The second base 62 has a receiving portion 82 that receives the axial portion 81 of the first base 61, and a sliding portion 84 that slides on the sloped surface 83 provided in the first base 61. The receiving portion 82 has a bottom surface 82a that is opposed to the end surface 81a of the axial portion 81, and an outer peripheral surface 82b that is opposed to the outer peripheral surface 81b of the axial portion 81. The bottom surface 82a is a substantially flat surface but should not be limited to this. The outer peripheral surface 82b is a slant surface that slants obliquely relative to the bottom surface 82a. The sliding portion 84 is arranged to protrude into the internal space of the receiving portion 82. When the first base 61 and the second base 62 are overlaid, the sliding portion 84 is protruded radially inward of the rotational axis AX regarding the pivoting of the second insert 72. The sliding portion 84 has a projected part 84a. When the sliding portion 84 finishes in sliding across the sloped surface 83, the projected part 84a of the sliding portion 84 is inserted into a recess 81c of the axial portion 81 (See FIG. 6).

Note that embodiments are obviously envisioned where the second base 62 is provided with the axial portion 81 and the first base 61 is provided with the receiving portion 82. Embodiments are naturally envisioned where the second base 62 is provided with the sloped surface 83 and the first base 61 is provided with the sliding portion 84. Note that, the axial portion 81 and the receiving portion 82 are provided for a purpose of positioning when stacking the first and second bases 61 and 62 and/or for a purpose of enhancing a rotational stability of the first and second bases 61 and 62.

The first and second bases 61,62 are configured to effect magnetic attraction and/or repulsion (magnetic attraction in the case of FIG. 9) between the first and second bases 61,62 when the first and second bases 61,62 are overlaid. Furthermore, the second base 62 is rotatable relative to the first base 61 in accordance with the magnetic attraction and/or repulsion to allow the second insert 72 to pivot towards the slit 46. Accordingly, the stop member 50 with improved operability can be provided.

There are various ways in terms of how the above-described magnetic attraction and/or repulsion is effected. In some cases, the magnetic attraction is effected based on the use of at least one permanent magnet. In some cases, the magnetic repulsion is effected based on the use of permanent magnets respectively provided in the first and second bases 61,62.

Specifically, the following cases are envisaged: (i) the first base 61 has one or more permanent magnets, and the second base 62 has one or more magnetic bodies; (ii) the first base 61 has one or more magnetic bodies, and the second base 62 has one or more permanent magnets; and (iii) the first base 61 has one or more permanent magnets, and the second base 62 has one or more permanent magnets. Use of the permanent magnet and the magnetic body can effect the magnetic attraction. Use of the permanent magnet and the permanent magnet can effect the magnetic attraction and/or repulsion. When the first base 61 and the second base 62 are overlaid, if a first pole (e.g. N-pole) of the permanent magnet in the first base 61 and a second pole (e.g. S-pole) of the permanent magnet in the second base 62 are arranged closely, the magnetic attraction would be effected between them. When the first base 61 and the second base 62 are overlaid, if a first pole (e.g. N-pole) of the permanent magnet in the first base 61 and a first pole (e.g. N-pole) of the permanent magnet in the second base 62 are arranged closely, the magnetic repulsion would be effected between them.

The permanent magnet has first and second poles as widely known. The first pole is one of N-pole and S-pole and the second pole is the other one of N-pole and S-pole. The magnetic body can be made of any material magnetically attachable to the permanent magnet and, for example, including one or more metals selected from Iron (Fe), Cobalt (Co), Nickel (Ni), and Gadolinium (Gd). Magnetic body can include stainless-steel such as martensite, ferrite, and austenite-ferrite. Note that the stainless-steel is an alloy and, in fact, includes Iron (Fe). The permanent magnet and magnetic body can take various shapes such as a bar, circular plate, and ring. Embodiments are envisioned where particulate permanent magnets and magnetic bodies are used.

The permanent magnet and/or magnetic body can be variously provided in the first base 61 and the second base 62. Embodiments are envisioned where the permanent magnet and/or magnetic body is embedded in the first base 61 through insert-molding or other methods. Embodiments are envisioned where the permanent magnet and/or magnetic body is fitted with or secured, by adhesive, to the first base 61. Embodiments are envisioned where the first base 61 is provided with a housing for hosing the permanent magnet and/or magnetic body. Similar embodiments are envisioned for the second base 62 either.

Embodiments are envisioned where the first member 51 (or the first base 61) or the second member 52 (or the second base 62) itself is made of magnetic material. For example, the first member 51 or the second member 52 is produced by casting of magnetic metal. Attachment of the first member 51 to the first fastener tape 11 can be achieved by any methods such as sewing and gluing. The same applies to attachment of the second member 52 to the second fastener tape 12. Note that, in typical cases, the first member 51 is fixed to the first fastener tape 11 as a result of insert-molding using a plastic/resin. Likewise, the second member 52 is fixed to the second fastener tape 12. In cases where the first member 51 (or the first base 61) or the second member 52 (or the second base 62) itself is made of magnetic material, the first base 61 or the second base 62 can additionally have a permanent magnet or magnetic body.

Referring to FIGS. 10-13, embodiments will be described where the first base 61 is provided with a first housing 101 for housing the first permanent magnet 111 and the second base 62 is provided with a second housing 102 for housing the second permanent magnet 112. Note that replacing one of the first and second permanent magnets 111, 112 with magnetic body can also be understandable. In other words, one can read the following descriptions with replacing one of the first and second permanent magnets 111, 112 with magnetic body.

FIG. 10 is a schematic bottom view of the first member 51 without illustration of a first cover 121. FIG. 11 is a schematic cross-sectional view of the first member 51 taken along a chain line X11-X11 in FIG. 10, illustration of a first permanent magnet 111 and the first cover 121 are omitted. FIG. 12 is a schematic top view of the second member 52, illustration of a second cover 122 is omitted. FIG. 13 is a schematic cross-sectional view of the second member 52 taken along a chain line X13-X13 in FIG. 12, illustration of a second permanent magnet 112 and the second cover 122 are omitted.

The first base 61 has the first housing 101 that houses the first permanent magnet 111. In some embodiments, the first housing 101 is provided to form a hollow in the axial portion 81. In some embodiments, the first housing 101 has an opening OP101 for introducing the first permanent magnet 111 from the opposite side of the end 91 (e.g. the end surface 81a) of the axial portion 81. The first permanent magnet 111 is introduced into the first housing 101 via the opening OP101 of the first housing 101. In some embodiments, the first housing 101 has a bottom 106 at the side of the end 91 of the axial portion 81. Note that, the first housing 101 has a circumferential wall surface 101a extending along the depth direction of the first housing 101 and a bottom surface 101b that is crossing or orthogonal to the depth direction of the first housing 101.

Cross-sectional shape of the first housing 101 in a plane orthogonal to the depth direction of the first housing 101 may take any shape such as a circle, triangle, rectangle and pentagon. It is envisioned that the cross-sectional shape of the first housing 101 changes along the depth direction of the first housing 101. Note that, the depth direction of the first housing 101 matches or is parallel to the axial direction AX1 of the axial portion 81. Note that, the axial direction AX1 of the axial portion 81 is co-axially arranged with the rotational axis AX regarding the pivoting of the second insert 72.

The bottom 106 of the first housing 101 is positioned in the proximity of the end 91 (e.g. the end surface 81a) of the axial portion 81. Distance between the bottom 106 of the first housing 101 and the end 91 of the axial portion 81 may be reduced, thus increasing magnetic permeability. First thinned portion 108 is provided between the end surface 81a of the axial portion 81 and the bottom surface 101b of the first housing 101. It is envisioned that one or more magnetically permeable holes are arranged in the first thinned portion 108 to further facilitate transmission of magnetic field lines there-through. The magnetically permeable holes are holes with permeability of magnetic fields and should not be limited to a space. The first thinned portion 108 is not necessarily a layer-like portion with a constant thickness.

The second base 62 has the second housing 102 that houses the second permanent magnet 112. In some embodiments, the second housing 102 of the second base 62 is provided at the opposite side relative to the receiving portion 82 of the second base 62. In some embodiments, the second housing 102 has an opening OP102 for introducing the second permanent magnet 112 from the opposite side of the opening of the receiving portion 82. The second permanent magnet 112 is introduced into the second housing 102 via the opening OP102 of the second housing 102. In some embodiments, the second housing 102 has a bottom 107 at the side of the receiving portion 82. Note that, the second housing 102 has a circumferential wall surface 102a extending along the depth direction of the second housing 102 and a bottom surface 102b crossing or orthogonal to the depth direction of the second housing 102.

Cross-sectional shape of the second housing 102 in a plane orthogonal to the depth direction of the second housing 102 can take any shape such as a circle, triangle, rectangle, and pentagon, for example. It is envisioned that the cross-sectional shape of the second housing 102 changes along the depth direction of the second housing 102. Note that the depth direction of the second housing 102 is opposite to the depth direction of the receiving portion 82.

The bottom 107 of the second housing 102 is positioned in the proximity of the bottom 92 (e.g. the bottom surface 82a) of the receiving portion 82. Distance between the bottom 107 of the second housing 102 and the bottom 92 of the receiving portion 82 may be reduced, thus increasing magnetic permeability. Second thinned portion 109 is provided between the bottom 92 (e.g. the bottom surface 82a) of the receiving portion 82 and the bottom 107 (e.g. the bottom surface 102b) of the second housing 102. It is envisioned that one or more magnetically permeable holes are arranged in the second thinned portion 109 to further facilitate transmission of magnetic field lines there-through. The magnetically permeable holes are holes with permeability for magnetic fields lines and should not be limited to a space. The second thinned portion 109 is not necessarily a layer-like portion with a constant thickness.

In some embodiments, the depth D101 of the first housing 101 of the first base 61 is greater than the depth D102 of the second housing 102 of the second base 62. This facilitates that the first housing 101 can have a greater accommodating space in a limited volume of the first base 61 provided with the axial portion 81. This facilitates to increase the size of the first permanent magnet 111 arranged in the first housing 101.

In some embodiments, the width W102 of the second housing 102 in a plane orthogonal to the depth direction of the receiving portion 82 is greater than the width W101 of the first housing 101 in a plane orthogonal to the axial direction of the axial portion 81. This facilitates that the second housing 102 can have a greater housing space in a limited volume of the second base 62 provided with the receiving portion 82. This facilitates to increase the size of the second permanent magnet 112 arranged in the second housing 102.

Each of the permanent magnet 111, 112 has first and second poles arranged along the rotational axis AX regarding the pivoting of the second insert 72. Arrangement direction D111, D112 (See FIG. 9) of the first and second poles in the first permanent magnet 111 and/or the second permanent magnet 112 are parallel to the rotational axis AX regarding the pivoting of the second insert 72 (See FIG. 1). The arrangement direction D111 of the first and second poles of the first permanent magnet 111 housed in the first housing 101 is parallel to the depth direction of the first housing 101 and/or the axial direction AX1 of the axial portion 81. The arrangement direction D112 of the first and second poles of the second permanent magnet 112 housed in the second housing 102 is parallel to the depth direction of the second housing 102 and/or the depth direction of the receiving portion 82.

In some embodiments, the first permanent magnet 111, housed in the first housing 101 of the first base 61, is shaped like a cylinder and, in the other hand, the second permanent magnet 112, housed in the second housing 102 of the second base 62, is shaped like a circular plate. This facilitates to allow the permanent magnet to exert greater magnetic force in a limited volume of the base portion provided with the axial portion 81 or the receiving portion 82. Likewise, in cases where the permanent magnet is replaced by magnetic body, the extent of magnetic interaction may be greater. As indicated above, one out of the two permanent magnets can be replaced by a magnetic body.

The cross-sectional shape of the first housing 101 and the cross-sectional shape of the first permanent magnet 111 (housed in the first housing 101) in a plane orthogonal to the depth direction of the first housing 101 are the same or different. Typically, both are shaped like a circle, facilitating smoother insertion of the permanent magnet into the housing. The cross-sectional shape of the second housing 102 and the cross-sectional shape of the second permanent magnet 112 (housed in the second housing 102) in a plane orthogonal to the depth direction of the second housing 102 are the same or different. Typically, both are shaped like a circle, facilitating smoother insertion of the permanent magnet into the housing.

Embodiments are envisaged where one or more position-restricting portion (e.g. a protrusion, a recess or combination of them) for restricting displacement of the permanent magnet is provided in one or both housings.

As a method for securing the first permanent magnet 111 in the first housing 101, various manners are envisioned such as gluing, fitting or closing by a cover. The same applies to a method for securing the second permanent magnet 112 in the second housing 102.

With reference to FIGS. 14-19, embodiments will be described where the opening OP101 of the first housing 101 is closed by a first cover 121, and the opening OP102 of the second housing 102 is closed by a second cover 122. In particular, embodiments will be described where the first cover 121 is secured, by fitting, to the first member 51 (or the first base 61) and the second cover 122 is secured, by fitting, to the second member 52 (or the second base 62), but should not be limited to this. For example, additionally or alternatively to the fitting, the cover can be fixed to the base portion by adhesive.

FIG. 14 is a schematic perspective view of the first cover 121. FIG. 15 is a schematic perspective view of the second cover 122. FIG. 16 is a schematic bottom view of the first member 51 in which the first cover 121 is attached to the first base 61. FIG. 17 is a schematic cross-sectional view of the first member 51 taken along a chain line X17-X17 in FIG. 16 with the first cover 121 attached to the first base 61. FIG. 18 is a schematic top view of the second member 52 with the second cover 122 attached to the second base 62. FIG. 19 is a schematic cross-sectional view of the second member 52 taken along a chain line X19-X19 in FIG. 18 with the second cover 122 attached to the second base 62.

Each of the first and second cover 121,122 has a covering portion 131 and one or more engaging protrusions 132. In the illustrated case, each cover is provided with two engaging protrusions 132. The covering portion 131 is a portion that covers the opening of the housing into which the permanent magnet or the magnetic body is inserted. The engaging protrusion 132 is a portion that prevents the cover from coming off the stop member or the base portion. Each engaging protrusion 132 has a post 133 provided on the covering portion 131 and an engagement head 134 provided at the end of the post 133. Embodiments are envisaged where the covering portion 131 is provided with a rotation stop 135 as illustrated. Note that, in the case where adhesive is used, the engaging protrusions 132 can be omitted.

The first and second bases 61,62 have third and fourth housings 103, 104 respectively that receive a respective covering portion 131 of the cover 121, 122 so that the cover is suppressed from coming off. The depth of the third and fourth housings 103,104 may be set equal to the thickness of a respective covering portion 131 of the cover 121,122. Note that the third housing 103 is in spatial communication with the first housing 101. Likewise, the fourth housing 104 is in spatial communication with the second housing 102.

In cases where each cover 121,122 is provided with the engaging protrusion 132, the first and second bases 61,62 have respective first and second engaged portions 141,142 with which the engaging protrusions 132 are respectively engaged. The first engaged portion 141 is provided radially outwardly offset from the axial direction AX1 of the axial portion 81. Therefore, when engaged with the first engaged portion 141, the engaging protrusion 132 of the first cover 121 is positioned radially outwardly offset from the axial direction AX1 of the axial portion 81. The first engaged portion 141 may be provided to penetrate through the outer peripheral surface 81b of the axial portion 81 and a surface of the first base 61 at the opposite side of the axial portion 81, but not necessarily limited to this. The first engaged portion 141 has a locking surface 151 by which the engagement head 134 of the engaging protrusion 132 is locked.

The second engaged portion 142 is positioned outwardly offset from the bottom 92 of the receiving portion 82. Therefore, when engaged with the second engaged portion 142, the engaging protrusion 132 of the second cover 122 is positioned outwardly offset from the bottom 92 of the receiving portion 82. The second engaged portion 142 is provided to penetrate through the outer peripheral surface 82b about the bottom surface 82a of the receiving portion 82 and a surface of the second base 62 at the opposite side of the receiving portion 82, but not necessarily limited to this. The second engaged portion 142 has a locking surface 152 by which the engagement head 134 of the engaging protrusion 132 is locked.

Operation of the stop member 50 of the present disclosure will be described with reference to FIGS. 20 and 21. FIGS. 20 and 21 are a schematic view illustrating that, while the first and second bases 61,62 are magnetically attached, the sliding portion 84 slides down a sloped surface 83 and the second insert 72 of the second member 52 moves toward the slit 46 of the slider 40. FIG. 20 illustrates a condition before the second insert 72 enters into the slider 40 via the slit 46 of the slider 40. FIG. 21 illustrates a condition after the second insert 72 has entered into the slider 40 via the slit 46 of the slider 40.

Firstly, in order to close the first and second fastener stringers 31, 32, the first and second bases 61 and 62 are overlaid. Note that, the first insert 71 has been inserted into the slider 40 beforehand. The slider 40 is held stationary on the first member 51. When the first and second bases 61 and 62 are overlaid, the second base 62 moves toward the first base 61 in accordance with the magnetic attraction effected between them. The axial portion 81 of the first base 61 enters into the receiving portion 82 of the second base 62. The sliding portion 84 touches the sloped surface 83. Reduction in the interspace between the first and second bases 61 and 62 is accompanied by sliding movement of the sliding portion 84 on the sloped surface 83. Accordingly, the second base 62 rotates relative to the first base 61 and the second insert 72 pivots about the rotational axis AX toward the slit 46 of the slider 40. Finally, the second insert 72 enters into the slider 40 via the slit 46 of the slider 40. In short, the second base 62 moves toward the first base 61 in accordance with the magnetic attraction in the axial direction of the rotational axis AX regarding the pivoting of the second insert 72, and the second insert 72 pivots about the rotational axis AX.

As shown in FIG. 21, following that the second insert 72 has entered into the slider 40 via the slit 46 of the slider 40, the slider 40 is moved frontward and the fastener stringers 31,32 are closed. In particular, the first fastener element 21 and the third fastener element 23 are engaged and in turn, the first fastener elements 21 and the second fastener elements 22 are engaged.

Magnetic attraction between the first and second bases 61 and 62 cause the rotation of the second base 62 relative to the first base 61 while the first base 61 and the second base 62 approach one another. For a person operating the stop member 50, just overlaying the first base 61 and the second base 62 would let the second insert 72 automatically pivot towards the slit 46 of the slider 40. Operational burden for inserting the second insert 72 into the slit 46 of the slider 40 would be omitted. Even if the second insert 72 failed to insert into the slit46 of the slider 40 for some reasons, operational burden for moving the second insert 72 toward the slit 46 of the slider 40 would be reduced. It is conceived that operation for moving the second insert 72 toward the slit 46 of the slider 40 is not easy for infants or elderly people. The stop member 50 of the present disclosure may be easily handled by such people.

With reference to FIGS. 22-26, embodiments will be described where the second insert 72 moves toward the slit 46 of the slider 40 based on magnetic repulsion between the first and second permanent magnets 111 and 112 of the first and second bases 61 and 62. That is, in the above descriptions, the first and second bases 61,62 are configured to effect magnetic attraction between the first and second bases 61,62 when the first and second bases 61,62 are overlaid. Also, the second base 62 rotates relative to the first base 61 in a process of magnetic attachment of the first and second bases 61,62 according to the magnetic attraction. In contrast, in the following descriptions, the first and second bases 61,62 are configured to effect magnetic repulsion when the first and second bases 61,62 are overlaid. Also, the second base 62 rotates relative to the first base 61 in accordance with the magnetic repulsion. Even in such a case, operational burden for inserting the second insert 72 into the slit 46 of the slider 40 would be omitted or reduced. Note that embodiments will be described where the first base 61 is not provided with the axial portion 81 and the sloped surface 83, and the second base 62 is not provided with the receiving portion 82 and the sliding portion 84. However, embodiments are envisioned where they are provided with these omitted portions. Note that the base portion 61,62 are portions to be overlaid, and rotation based on magnetic attraction and/or repulsion would be more easily imparted.

FIG. 22 is a schematic view of the first member 51 having the first permanent magnet 111 of bar magnet. FIG. 23 is a schematic view of the second member 52 having the second permanent magnet 112 of bar magnet. FIG. 24 is a schematic cross-sectional view illustrating an embodiment where the first permanent magnet 111 housed in the first housing 101 of the first base 61 is covered by the first cover 121 and the second permanent magnet 112 housed in the second housing 102 of the second base 62 is covered by the second cover 122. FIG. 25 is a schematic view illustrating that the first base 61 of the first member 51 and the second base 62 of the second member 52 are overlaid. The second insert 72 moves toward the slit 46 of the slider 40 in accordance with magnetic repulsion effected between the first permanent magnet 111 of the first base 61 and the second permanent magnet 112 of the second base 62. FIG. 26 is a schematic view illustrating that the second insert 72 has been inserted in the slider 40 via the slit 46 of the slider 40 in accordance with magnetic repulsion effected between the first permanent magnet 111 of the first base 61 and the second permanent magnet 112 of the second base 62. Magnetic repulsion between the first poles of the first and second permanent magnets 111 and 112 and/or between the second poles of the first and second permanent magnets 111 and 112 would be used for pivoting the second insert 72.

As shown in FIGS. 22 and 23, each of the permanent magnets 111, 112 has first and second poles arranged in a plane crossing or orthogonal to the rotational axis AX regarding the pivoting of the second insert 72. Arrangement direction D111 of the first and second poles in the first permanent magnet 111 of the first base 61 is crossing or orthogonal (i.e. non-parallel) to the rotational axis AX regarding the pivoting of the second insert 72 (See FIG. 1). Arrangement direction D112 of the first and second poles in the second permanent magnet 112 of the second base 62 is crossing or orthogonal (i.e. non-parallel) to the rotational axis AX regarding the pivoting of the second insert 72.

In some embodiments, the first and second bases 61 and 62 are engaged in rotatable manner, not necessarily limited to this though. As shown in FIG. 24, the first base 61 has one or more engaging portion 161 and the second base 62 has one or more engaged portions 162. The engaging portion 161 is a protrusion and the engaged portion is a recess, but these can be interchanged. The recess extends in the circumferential direction regarding the rotational axis AX, for example. Accordingly, rotation of the second base 62 relative to the first base 61 or rotation of the first base 61 relative to the second base 62 in accordance with magnetic force effected between the first and second permanent magnets 111 and 112 would be facilitated.

At a situation shown in FIG. 25, the first pole of the second permanent magnet 112 is positioned near the first pole of the first permanent magnet 111. Likewise, the second pole of the second permanent magnet 112 is positioned near the second pole of the first permanent magnet 111. The first and second bases 61 and 62 are sandwiched between thumb and index finger of a hand of human. Thus, the first permanent magnet 111 cannot move away from the second permanent magnet 112 along the rotational axis AX. Likewise, the second permanent magnet 112 cannot move away from the first permanent magnet 111 along the rotational axis AX. The first pole of the second permanent magnet 112 moves away from the first pole of the first permanent magnet 111 in a plane crossing or orthogonal to the rotational axis AX in accordance with magnetic repulsion effected between the same poles of the first and second permanent magnets 111 and 112 and similarly, the second pole of the second permanent magnet 112 moves away from the second pole of the first permanent magnet 111. That is, the rotation of the second base 62 relative to the first base 61 starts in accordance with magnetic repulsion effected between the same poles of the first and second permanent magnets 111 and 112. Directionality can be given to the rotational direction of the second base 62 in accordance with the adjustment of force for sandwiching them between the thumb and index finger. The second insert 72 pivots toward the slit 46 of the slider 40 in accordance with the above-described rotation of the second base 62 relative to the first base 61. It is an option for the first and second bases 61 and 62 to be associated in rotatable manner, but such a case allows one to control more easily a rotational direction of the second base 62 as described above.

FIGS. 27 to 30 describe embodiments where the second insert 72 is inserted into the slider 40 via the slit 46 of the slider 40 in accordance with magnetic attraction effected between the first and second permanent magnets 111 and 112 of the first and second bases 61 and 62. The second pole of the second permanent magnet 112 is placed near the first pole of the first permanent magnet 111 and likewise, the first pole of the second permanent magnet 112 is placed near the second pole of the first permanent magnet 111. The second pole of the second permanent magnet 112 moves closer to the first pole of the first permanent magnet 111 in a plane crossing or orthogonal to the rotational axis AX in accordance with magnetic attraction effected between the opposite poles of the first and second permanent magnets 111 and 112 and likewise, the first pole of the second permanent magnet 112 moves closer to the second pole of the first permanent magnet 111. That is, the rotation of the second base 62 relative to the first base 61 starts in accordance with magnetic attraction effected between the opposite poles of the first permanent magnet 111 and the second permanent magnet 112. This is accompanied by the second insert 72 pivoting toward the slit 46 of the slider 40. It is an option for the first base 61 and the second base 62 to be associated in rotatable manner, but such a case allows one to control more easily the rotational direction of the second base 62 as described above.

Based on the above teachings, a skilled person in the art would be able to add various modifications to the respective embodiments. Reference numbers in Claims are just for reference and should not be referred for a purpose of narrowly construing the scope of claims. Embodiments are envisioned where only magnetic repulsion is caused when the first base and the second base are overlaid, and the second insert pivots into the slit.
