[0005] Patent Document 1: Japanese Patent No. 7135104 Utility Model Content
[0006] Pulling a zipper (such as a zipper tape or a slider) or an article with a zipper (such as clothing) in any direction may cause the insertion portion temporarily inserted into the slider to be displaced, thereby preventing the slider from moving smoothly in a direction away from the stopper (i.e., starting to slide).
[0007] One method of the present disclosure involves a stopper that is a detachable stopper for a zipper, and the zipper becomes a closed state by the forward movement of the slider, and becomes an open state by the backward movement of the slider. The stopper includes: a first component, which includes a first base and a first insertion portion inserted into the slider; and a second component, which includes a second base that can be magnetically engaged with the first base, and a second insertion portion that is inserted into the slider from the side of the slider corresponding to the magnetic engagement between the first base and the second base. Synchronously with the slider becoming an assembled state capable of moving forward after the insertion of the first insertion portion and the second insertion portion into the slider is completed, the first base and the second base can abut against each other at at least one position to prevent the second insertion portion from being displaced toward a side opposite to the insertion direction of the second insertion portion into the slider.
[0008] In some embodiments, the first base portion and the second base portion respectively include a first abutting portion and a second abutting portion for abutting against each other at at least one location, and the first abutting portion and the second abutting portion can abut against each other in a manner that can be displaced in a direction away from each other. The first abutting portion and the second abutting portion can be respectively formed into a first corner portion and a second corner portion or a stepped portion. Corresponding to the advancement of the slider away from the stop, one of the first abutting portion and the second abutting portion is displaced away from the other, and a gap can be formed therebetween.
[0009] In some embodiments, the first abutting portion projects along an axis parallel to the direction in which the first base portion and the second base portion are magnetically joined to each other, or projects along an axis orthogonal to the magnetic joining direction. As an addition or alternative, the first abutting portion has a first contact surface capable of contacting the second abutting portion, and the second abutting portion has a second contact surface capable of contacting the first abutting portion. The first contact surface and the second contact surface can be formed along the direction in which the first base portion and the second base portion are magnetically joined to each other.
[0010] In some embodiments, one or both of the first contact surface and the second contact surface form an angle of 30° or less, 25° or less, or 20° or less with respect to a line parallel to the direction in which the first base portion and the second base portion are magnetically joined to each other when the assembled state is established.
[0011] In some embodiments, the first contact surface is positioned radially outside with respect to at least one magnetic axis or central axis of at least one magnet or magnetic body at least partially embedded in the first base portion when the assembled state is established; and the second contact surface is positioned radially outside with respect to at least one magnetic axis or central axis of at least one magnet or magnetic body at least partially embedded in the second base portion when the assembled state is established.
[0012] In some embodiments, the slider includes an upper wing plate, a lower wing plate, and a connecting column connecting the upper wing plate and the lower wing plate. The first base portion and the second base portion can coincide in the vertical direction parallel to the extending direction of the connecting column of the slider, and include a first hook portion and a second hook portion. The first hook portion and the second hook portion abut against each other corresponding to the advancement of the slider away from the stop to prevent the separation of the first base portion and the second base portion from each other in the vertical direction, and the hook head portion of the first hook portion includes the first abutting portion.
[0013] In some embodiments, corresponding to the advancement of the slider away from the stop, one of the first hook portion and the second hook portion approaches the other, and one of the first abutting portion and the second abutting portion is displaced away from the other.
[0014] In some embodiments, the second base portion includes an inclined portion having more than one inclined surface, the first base portion includes a sliding portion that slides on the more than one inclined surface, and the abutment at at least one location includes the abutment between the inclined portion and the sliding portion that occurs just after the sliding portion finishes sliding on the more than one inclined surface.
[0015] In some embodiments, the inclined portion has a thickness that gradually decreases corresponding to the at least one inclined surface, and the corner of the end portion of the inclined portion having a thinner thickness is chamfered. In addition to the at least one inclined surface (referred to as the first inclined surface), the inclined portion may further have a stop surface. The stop surface may include a vertical surface or an inclined surface (referred to as the second inclined surface). The first inclined surface and the second inclined surface can satisfy the relative relationships described in this specification.
[0016] In some embodiments, the second base portion includes: a first inclined portion having a first inclined surface; and a second inclined portion having a second inclined surface, and the first base portion includes: a first sliding portion that slides on the first inclined surface; and a second sliding portion that slides on the second inclined surface. Synchronously with the completion of the insertion of the first insertion portion and the second insertion portion into the slider and the slider becoming an assembled state in which it can advance, the first inclined portion and the first sliding portion can abut against each other to prevent the second insertion portion from being displaced toward the side opposite to the insertion direction of the second insertion portion into the slider. As an addition or alternative, synchronously with the completion of the insertion of the first insertion portion and the second insertion portion into the slider and the slider becoming an assembled state in which it can advance, the second inclined portion and the second sliding portion can abut against each other to prevent the second insertion portion from being displaced toward the side opposite to the insertion direction of the second insertion portion into the slider.
[0017] In some embodiments, the first base portion and the second base portion are shaped such that during the process of magnetic engagement between the first base portion and the second base portion, the second base portion rotates as the second insertion portion is inserted into the slider.
[0018] In some embodiments, one of the first base portion and the second base portion has more than one inclined surface, and the other of the first base portion and the second base portion has more than one sliding portion that slides on the more than one inclined surface, and the sliding portion slides on at least one inclined surface corresponding to the magnetic engagement between the first base portion and the second base portion.
[0019] In some embodiments, the second insertion portion has a thickness that gradually decreases toward its insertion end into the slider, and / or the second insertion portion has a guiding surface that slopes forward corresponding to the connecting post that moves away from the slider laterally when the assembled state is established.

[0061] Hereinafter, various implementation modes and features will be described with reference to the drawings. Those skilled in the art can combine the various implementation modes and / or the various features without excessive explanation, and can also understand the synergistic effects brought by the combination. Repetitive explanations between implementation modes are omitted in principle. With the main purpose of describing the utility model, the drawings are simplified for easy drawing. Each feature should be understood as a general feature that is not only effective for the stop disclosed in the present utility model, but also common to other various stops not disclosed in this specification.
[0062] Hereinafter, the description will be made using the directions defined below. The front - rear direction (F - B) is consistent with the moving direction of the slide fastener. Specifically, the front is consistent with the moving direction of the slide fastener that makes the zipper in a closed state, and the rear is consistent with the moving direction of the slide fastener that makes the zipper in an open state. The left - right direction (L - R) is consistent with the width direction of the zipper. The up - down direction (U - D) is consistent with the thickness direction of the zipper and the extending direction of the connecting post of the slide fastener. A three - dimensional coordinate system is determined by the front - rear direction, the left - right direction, and the up - down direction.
[0063] The zipper 1 includes left and right zipper chain tapes 2a, 2b, a slide fastener 5, and a stop 15. The left zipper chain tape 2a includes a zipper tape 3a and a plurality of zipper teeth 4a. The right zipper chain tape 2b includes a zipper tape 3b and a plurality of zipper teeth 4b. The left and right zipper tapes 3a, 3b are soft woven fabrics or knitted fabrics. The left and right zipper teeth 4a, 4b are installed at a certain interval on the longer opposite edges of the left and right zipper tapes 3a, 3b. In the illustrated example, each of the zipper teeth 4a, 4b is made of resin, but it can also be made of metal, or it can also be a unit structure of a helical monofilament. In the helical monofilament, engaging heads are formed at a certain interval, and each unit structure including one engaging head forms each zipper tooth.
[0064] The illustrated zipper teeth 4a and 4b include a base portion 41, a neck portion 42, and a head portion 43. The base portion 41 is fixed to the zipper tapes 3a and 3b, and the neck portion 42 tapers toward the middle on both the front and rear sides. In addition, the neck portion 42 and the head portion 43 are located outside the zipper tapes compared to the base portion 41, and are outside the tape surface of the zipper tapes. As an option, fins 44 are provided on both the front and rear sides of the neck portion 42. Correspondingly, a groove extending in the front-rear direction is formed on the top surface (left side surface or right side surface) of the head portion 43. When the left and right zipper teeth 4a and 4b are engaged, one fin 44 is inserted into the groove of the other, thereby enabling resistance to pushing in the up-down direction.
[0065] The slider 5 includes an upper wing plate 51, a lower wing plate 52, and a connecting post 53 that connects the upper wing plate 51 and the lower wing plate 52 at their front end portions. Flanges 54 are formed on the left and right side edges of one or both of the upper wing plate 51 and the lower wing plate 52. The upper wing plate 51 and the lower wing plate 52 are arranged facing each other in the up-down direction. The connecting post 53 has a tapered rear end portion that narrows in width toward the rear. The flanges 54 are formed at a relatively low height to form a gap for the zipper tapes 3a and 3b (and the second insertion portion 7b described later) to pass through. With such a structure of the slider 5, a Y-shaped tooth path is formed that includes two front openings on both sides of the connecting post 53 and one rear opening located behind the connecting post 53.
[0066] When the slider 5 advances, the non-engaged left and right zipper teeth 4a and 4b enter the inside of the slider 5 through the left and right front openings respectively, and are engaged at a position behind the connecting post 53. The engaged left and right zipper teeth 4a and 4b exit from the inside of the slider 5 through the rear opening. When the slider 5 retreats, the engaged left and right zipper teeth 4a and 4b enter the inside of the slider 5 through the rear opening, and the engagement is released at a position behind the connecting post 53. The non-engaged left and right zipper teeth 4a and 4b exit from the inside of the slider 5 through the left and right front openings respectively.
[0067] The stop code 15 includes a first member 11 and a second member 12 which are structures that can be magnetically joined to each other, i.e., can be joined magnetically but are physically or structurally separated, whereby the left and right zipper chains 2a, 2b can be separated. The first member 11 includes: a first base portion 6a; and a first insertion portion 7a which is inserted into the slider 5 (e.g., from the rear of the slider 5), and the first base portion 6a and the first insertion portion 7a are fixed to the left zipper tape 3a (e.g., by insert molding) in a manner adjacent to the position of the rear end of the left zipper teeth 4a. The second member 12 includes: a second base portion 6b which can be magnetically joined to the first base portion 6a; and a second insertion portion 7b which is inserted into the slider 5 from the side of the slider 5 corresponding to the magnetic joining of the first base portion 6a and the second base portion 6b to each other, and the second base portion 6b and the second insertion portion 7b are fixed to the right zipper tape 3b in a manner adjacent to the position of the rear end of the right zipper teeth 4b. The first base portion 6a and the second base portion 6b can be aligned in the vertical direction. The first insertion portion 7a and the second insertion portion 7b can be engaged (fitted) inside the slider 5.
[0068] The first base portion 6a includes: a columnar portion 65 which has a magnet or a magnetic body; and an outer peripheral portion 66 which is located on the outer periphery of the columnar portion 65 (refer to Figure 2 ). Preferably, the magnet or the magnetic body is partially exposed in the columnar portion 65, whereby the magnetic attraction between the first base portion 6a and the second base portion 6b is enhanced. As described later, the outer peripheral portion 66 includes a sliding portion 32, a first hook portion 21, and a first abutting portion 61, and one or more or all of these components are disposed behind the columnar portion 65, but are not limited thereto. A guide rod 8 is formed at the front end portion of the first base portion 6a, and the guide rod 8 extends along the first insertion portion 7a and is spaced apart from the first insertion portion 7a. A groove for inserting the flange 54 of the slider 5 is formed between the first insertion portion 7a and the guide rod 8, and displacement of the slider 5 at the assembly position described later can be suppressed.
[0069] The first insertion portion 7a extends forward from the first base portion 6a and has a thickness capable of being inserted into the rear opening of the slider 5 (i.e., between the upper wing plate 51 and the lower wing plate 52). Preferably, the first insertion portion 7a is configured to at least partially accommodate the second insertion portion 7b. For example, it includes an upper plate 71 and a lower plate 72 that are disposed opposite to each other in the vertical direction. By at least partially inserting the second insertion portion 7b between the upper plate 71 and the lower plate 72 of the first insertion portion 7a, separation of the first member 11 and the second member 12 in the vertical direction can be prevented. Both the upper plate 71 and the lower plate 72 are connected to the outer peripheral portion 66 of the first base portion 6a. The outer peripheral portion 66 has a stop wall 67 that protrudes downward at the portion connected to the lower plate 72. A groove that opens forward, backward, and to the right is provided directly above the stop wall 67. This groove is spatially connected to the accommodation space between the upper plate 71 and the lower plate 72, and thus does not hinder the insertion of the second insertion portion 7b into the accommodation space of the first insertion portion 7a. The stop wall 67 has a height that gradually decreases toward the right side, and guides the second insertion portion 7b in the clockwise direction (and then the second insertion portion 7b pivots in the counterclockwise direction) corresponding to the magnetic engagement between the first base portion 6a and the second base portion 6b. The first base portion 6a has an outer shape that is substantially rectangular in plan view, but other shapes can also be adopted.
[0070] The second base portion 6b includes: a bottom portion 68 that is shaped to at least partially accommodate the columnar portion 65 and has an upper surface 68a; and an outer peripheral portion 69 that is located on the outer periphery of the upper surface 68a of the bottom portion 68. A magnet or a magnetic body is exposed on the upper surface and / or the lower surface of the bottom portion 68, thereby enhancing the magnetic attraction between the first base portion 6a and the second base portion 6b. As will be described later, the outer peripheral portion 69 includes an inclined portion 31 having an inclined surface 31a, a second hook portion 22, and a second abutting portion 62. One or more of these components or all of them are disposed behind the bottom portion 68, but are not limited thereto.
[0071] The second insertion portion 7b extends forward from the second base portion 6b and has a thickness capable of being inserted into the gap of the slider 5 (typically, the gap between the flange 54 connected to the upper wing plate 51 and the flange 54 connected to the lower wing plate 52). More specifically, the second insertion portion 7b has a thin portion 75 that is inserted into the slider 5. The thin portion 75 can have a thickness that gradually decreases toward the insertion end (i.e., toward the left side), thereby facilitating its insertion. In particular, when the first insertion portion 7a is formed to accommodate the second insertion portion 7b, the thin portion 75 of the second insertion portion 7b is finally accommodated in the accommodation space of the first insertion portion 7a.
[0072] At the front end of the second insertion portion 7b, a half slider tooth 4c that engages with the slider teeth 4a on the left side is provided. The half slider tooth 4c has a half shape obtained by dividing the slider tooth into two halves. As an option, the half slider tooth 4c has a guide surface 4d that slopes forward corresponding to the connecting post 53 that is farther away from the slider 5 to the right when the assembled state is established. Thus, even if it is assumed that the second insertion portion 7b is located at a position slightly deviated to the right compared to the desired position, it is possible to promote the contact between the flange 54 of the slider 5 and the guide surface 4d when the slider 5 advances, and press the second insertion portion 7b to the left (for example, press it into the accommodation space of the first insertion portion 7a).
[0073] The second member 12 can have a brake lever 76 adjacent to the second insertion portion 7b. The brake lever 76 collides with the slider 5 when the second insertion portion 7b is inserted into the slider 5 from the side of the slider 5, thereby determining the insertion position of the second insertion portion 7b.
[0074] As Figure 6 shown, the first base 6a has a magnet M1 or a magnetic body, and the second base 6b has a magnet M2 or a magnetic body. The first base 6a and the second base 6b are magnetically joined by the magnetic force between the magnet M1 and the magnet M2 or by the magnetic force between the magnets M1, M2 and the magnetic body. Typically, the magnetic joining direction of the first base 6a and the second base 6b is the same as the up-down direction, and the two overlap in the up-down direction, but it is not limited thereto. The magnets M1, M2 have magnetic axes MA1, MA2 with respect to the magnetic flux flowing from the N pole to the S pole. A magnetic attractive force is generated between the magnets M1, M2 such that the magnetic axes MA1, MA2 are arranged coaxially. In addition, with respect to the magnetic body, the central axis is referred to instead of the magnetic axis.
[0075] As Figure 7 shown, the first base 6a and the second base 6b are shaped such that the second base 6b rotates as the second insertion portion 7b is inserted into the slider 5 during the magnetic joining process between the first base 6a and the second base 6b. Here, the second base 6b has an inclined surface 31a, and the first base 6a has a sliding portion 32 that slides on the inclined surface 31a. Corresponding to the magnetic joining between the first base 6a and the second base 6b, the sliding portion 32 slides on the inclined surface 31a (i.e., the magnetic attraction is converted into rotation). Corresponding to the sliding of the sliding portion 32 on the inclined surface 31a, the up-down interval between the first base 6a and the second base 6b decreases, and the second base 6b rotates relative to the first base 6a, and the second insertion portion 7b pivots counterclockwise (refer to Figure 7 ). In addition, an additional or alternative inclined surface can be provided on the first base 6a, and an additional or alternative sliding portion can be provided on the second base 6b. The number of pairs of the inclined surface and the sliding portion is not limited to 1, and can also be 2, 3, or more than 3.
[0076] The first base portion 6a has a first hook portion 21, and the second base portion 6b has a second hook portion 22. The first hook portion 21 and the second hook portion 22 engage with each other corresponding to the slider 5 moving away from the stop 15 forward, so as to prevent the first base portion 6a and the second base portion 6b from separating from each other in the vertical direction (see Figure 8 , Figure 9 ). Typically, the first hook portion 21 and the second hook portion 22 are positioned at positions radially outside (preferably adjacent to each other) compared with the inclined surface 31a and the sliding portion 32 (for example, relative to the magnetic axes MA1, MA2). In the circumferential direction with respect to the magnetic axis MA1, the first hook portion 21 and the inclined surface 31a (the inclined portion 31 described later) can be provided at different positions (for example, with an angular interval of 40 degrees or less). In the circumferential direction with respect to the magnetic axis MA2, the second hook portion 22 and the sliding portion 32 can be provided at different positions (for example, with an angular interval of 40 degrees or less).
[0077] More specifically, the first hook portion 21 includes a hook base portion 21p and a hook head portion 21q. The hook head portion 21q is connected to the lower end of the hook base portion 21p and protrudes to the left compared with the hook base portion 21p. The hook head portion 21q of the first hook portion 21 is located below the lower surface (top surface) of the columnar portion 65. The second hook portion 22 includes a hook base portion 22p and a hook head portion 22q. The hook head portion 22q is connected to the upper end of the hook base portion 22p and protrudes to the right compared with the hook base portion 22p. The hook head portion 22q of the second hook portion 22 is located above the upper surface of the bottom portion 68. When the first hook portion 21 and the second hook portion 22 engage, the upper surface of the hook head portion 21q and the lower surface of the hook head portion 22q face each other with a slight gap therebetween or at least partially contact each other.
[0078] Hereinafter, mainly with reference to Figures 10 to 12 it will be described. Figure 10 is a schematic perspective view of an assembly of the slider 5, the first member 11, and the second member 12 when the assembled state is established. Figure 11 is a schematic view showing the abutting state of the first abutting portion 61 and the second abutting portion 62 when the assembled state is established. Figure 12 is a schematic view showing the abutting state of the first hook portion 21 and the second hook portion 22 after the slider 5 moves forward away from the stop 15.
[0079] The assembled state means a state in which the slider 5 can move forward after the first insertion portion 7a and the second insertion portion 7b are inserted into the slider 5. In the above manner, the assembled state means a state in which the first insertion portion 7a is inserted into the slider 5 through the rear opening of the slider 5, and then the second insertion portion 7b is inserted into the slider 5 through the slit of the slider 5 corresponding to the magnetic engagement between the first base portion 6a and the second base portion 6b, but it is not limited thereto. The slider 5 can move forward after the assembled state is established to engage the left and right zipper teeth 4a, 4b.
[0080] Although the second insertion portion 7b reaches the expected insertion position corresponding to the magnetic engagement between the first base 6a and the second base 6b, there is still a possibility that the right zipper tape 3b is pulled to the right and the second insertion portion 7b is also linked to the right. In this way, if the slider 5 starts to move forward in a state out of the assembled state, a greater force is required to move the slider 5, which may give the user a sense of resistance that cannot be ignored when operating the slider 5. In the worst case, the slider 5 is hindered from moving forward, and the burden of magnetically engaging the first component 11 and the second component 12 again is generated.
[0081] In this embodiment, synchronously with the establishment of the assembly state in which the first insertion portion 7a and the second insertion portion 7b are inserted into the slider 5 and the slider 5 can move forward, the first base portion 6a and the second base portion 6b can abut against each other at at least one position to prevent the second insertion portion 7b from being displaced (for example, pivoted) toward the side opposite to the direction in which the second insertion portion 7b is inserted into the slider 5. Thus, it is possible to suppress the departure from the above-mentioned assembly state and promote the smooth operation of the slider 5. In addition, by the above-mentioned abutment at at least one position, the displacement of the second insertion portion 7b in the same direction as the direction in which the second insertion portion 7b is inserted into the slider 5 and the rotation of the second base portion 6b caused by the displacement are not prevented.
[0082] Reference Figure 11 To explain, when the sliding portion 32 finishes sliding on the inclined surface 31a, the second contact portion 62 of the second base 6b is displaced from the position directly below the first contact portion 61 of the first base 6a to the position adjacent to the right thereof and abuts against the first contact portion 61. By the first and second contact portions 61 and 62 adjacent to each other in this way, the second base 6b is prevented from rotating in the clockwise direction and the second insertion portion 7b is pivoted in the clockwise direction. In addition, the displacement of the second contact portion 62 from the position directly below the first contact portion 61 to the position on the right thereof is naturally generated as a result of the magnetic engagement of the first base 6a and the second base 6b. In addition, the abutment between the first contact portion 61 and the second contact portion 62 will not prevent the second base 6b from rotating in the counterclockwise direction and the second insertion portion 7b from pivoting in the counterclockwise direction.
[0083] The contact between the first contact portion 61 and the second contact portion 62 is a contact in a manner that allows displacement in a direction away from each other. Additionally, the contact between the first contact portion 61 and the second contact portion 62 permits the second insertion portion 7b to be forcibly withdrawn from the slider 5, and can be forcibly released by an operation of pulling out the second insertion portion 7b from the slider 5 when the assembled state is established. Therefore, even if the above-mentioned first contact portion 61 and second contact portion 62 are provided, the separation of the first member 11 and the second member 12 is not hindered. From the perspective of a detachable contact, it is preferable that the first contact portion 61 and the second contact portion 62 are formed into a corner portion or a stepped portion. The corner portion included in the corner portion or the stepped portion is preferably chamfered to have an inclined surface or a rounded surface. The first contact portion 61 can project along an axis parallel to the direction (or magnetic axis MA1) in which the first base portion 6a and the second base portion 6b are magnetically joined to each other, but is not limited thereto. The second contact portion 62 can project along the circumferential direction with respect to the direction (or magnetic axis MA2) in which the first base portion 6a and the second base portion 6b are magnetically joined to each other, but is not limited thereto.
[0084] The first contact portion 61 has a first contact surface 61c capable of contacting the second contact portion 62, and / or the second contact portion 62 has a second contact surface 62c capable of contacting the first contact portion 61. The first contact surface 61c and the second contact surface 62c are formed along the direction in which the first base portion 6a and the second base portion 6b are magnetically joined to each other when the assembled state is established. Typically, (i) both the first contact surface 61c and the second contact surface 62c are vertical surfaces, (ii) one of the first contact surface 61c and the second contact surface 62c is a vertical surface and the other is an inclined surface, or (iii) both the first contact surface 61c and the second contact surface 62c are inclined surfaces. As an option, one or both of the first contact surface 61c and the second contact surface 62c form an angle of 30° or less, 25° or less, or 20° or less with respect to a line parallel to the direction (such as the up-down direction) in which the first base portion 6a and the second base portion 6b are magnetically joined to each other when the assembled state is established (refer to Figure 27 )), whereby the separation of the two becomes smooth when the connection between the first member 11 and the second member 12 is released. Additionally, the first contact surface 61c is positioned at a position radially outside the magnet M1 with respect to the magnetic axis MA1 when the assembled state is established. In this way, the second contact surface 62c is positioned at a position radially outside the magnet M2 with respect to the magnetic axis MA2 when the assembled state is established.
[0085] The above-described first abutting portion 61 and second abutting portion 62 can be respectively provided at various positions in the first base portion 6a and the second base portion 6b. In some cases, the hook head portion 21q of the first hook portion 21 includes the first abutting portion 61, whereby the first abutting portion 61 can be smoothly included in the first base portion 6a without being affected by the space limitation in the first base portion 6a. Correspondingly, the second abutting portion 62 can be included in a portion (hereinafter referred to as the adjacent portion) that is adjacent to the second hook portion 22 in the circumferential direction of the outer peripheral portion 69 of the second base portion 6b with a space SP1 therebetween (for inserting the hook head portion 21q of the first hook portion 21). The adjacent portion can be located at a position adjacent to the radial outside of the inclined portion 31 with respect to the magnetic axis MA2. The space SP1 allows the first hook portion 21 (the first abutting portion 61) to be further displaced in a direction away from the adjacent portion (the second abutting portion 62) by the advancement of the slider 5 after the assembled state is established.
[0086] According to Figure 11 and Figure 12 the comparison, corresponding to the advancement of the slider 5 away from the stop 15, one of the first hook portion 21 and the second hook portion 22 approaches the other in the circumferential direction with respect to the magnetic axes MA1 and MA2, and one of the first abutting portion 61 and the second abutting portion 62 moves away from the other, forming a gap therebetween (in other words, the abutment between the first abutting portion 61 and the second abutting portion 62 is released). When the slider 5 retreats and reaches the assembled position, the connecting column 53 of the slider 5 is inserted between the first insertion portion 7a and the second insertion portion 7b. At this time, the second insertion portion 7b pivots in the clockwise direction, and similarly, the second base portion 6b rotates in the clockwise direction. In addition, the interval between the first abutting portion 61 and the second abutting portion 62 gradually decreases, and finally the two abut. As described above, the abutment between the first abutting portion 61 and the second abutting portion 62 can be forcibly released, so that the separation of the first component 11 and the second component 12 is not hindered.
[0087] The above-described various features can be applied to the following various modification examples individually or in any combination.
[0088] Refer to Figures 13 to 15A modified example will be described. In this modified example, as an alternative to the above-described manner, the sliding portion 32 abuts against the inclined portion 31 (wherein the inclined surface 31a is formed) immediately after the sliding on the inclined surface 31a is completed, thereby preventing the second member 12 from being displaced in the direction of exiting from the slider 5. In such a case, the same effect as the above-described manner can also be obtained. More specifically, in this modified example, the first abutting portion 61 is included in the sliding portion 32, and the second abutting portion 62 is included in the inclined portion 31. In other words, in the above-described embodiment, the first abutting portion 61 and the second abutting portion 62 are assigned to the first hook portion 21 and the adjacent portion, and as an alternative thereto, the first abutting portion 61 and the second abutting portion 62 can be assigned to the inclined portion 31 and the sliding portion 32. In the case of this modified example, it is easy to reduce the force required to separate the first member 11 and the second member 12. Of course, a combination of the above-described manner and this modified example can also be implemented.
[0089] The second base portion 6b has a concave portion 33 that is adjacent to the inclined portion 31 in the circumferential direction and houses the sliding portion 32 that has slid down from the inclined surface 31a. Typically, the bottom surface of the concave portion 33 is at the same height as the upper surface 65a of the bottom portion 68 (of course, a step can also be formed therebetween). The concave portion 33 defines a space SP1, and similarly to the space SP1, it allows the sliding portion 32 to be further displaced in a direction away from the inclined portion 31 after the assembly state is established by the advancement of the slider 5.
[0090] In the case where the first abutting portion 61 is not assigned to the first hook portion 21, the first hook portion 21 can be formed lower as shown in Figure 13 . In the illustrated example, the lower end surface of the first hook portion 21 is in the same plane as the lower surface of the columnar portion 65. As shown in Figure 14 , the inclined portion 31 has a thickness that gradually decreases corresponding to at least one inclined surface 31a, and a restraining surface 31b is formed at an end portion of the inclined portion 31 where the thickness is thinner. The restraining surface 31b, for example, hangs down from one end of at least one inclined surface 31a or inclines at an angle different from that of the inclined surface 31a. It is clear from Figure 15 that after the sliding portion 32 has slid on the inclined surface 31a and ended, it is located adjacent to the restraining surface 31b, and the reverse movement of the sliding portion 32 is blocked (typically, easily) by the abutment of the first base portion 6a and the second base portion 6b, more specifically, by the restraining surface 31b. Chamfering can also be performed on the corner portion of the end portion of the inclined portion 31 in such a way that a C surface, an R surface, etc. are formed between the inclined surface 31a and the restraining surface 31b. In addition, the restraining surface 31b is an element included in the above-described second contact surface 62c.
[0091] Figure 16 Shows along Figure 1Schematic end view of the first component 11 of the dash-dotted line X16-X16. The second insertion portion 7b has a thickness that gradually decreases toward its insertion end, and its insertion into the accommodation space of the first insertion portion 7a becomes smooth.
[0092] Refer to Figures 17 to 18 , and another modification will be described. Figure 17 Shows a state where the first abutting portion 61 of the first base portion 6a abuts against the second abutting portion 62 of the second base portion 6b and the first base portion 6a and the second base portion 6b are in contact when the assembled state is established. In this modification, it is also configured such that in synchronization with the establishment of the assembled state in which the slider 5 can advance after the first insertion portion 7a and the second insertion portion 7b are inserted into the slider 5, the first base portion 6a and the second base portion 6b can abut against each other at at least one portion to prevent the second insertion portion 7b from being displaced (e.g., laterally moved) in a direction opposite to the direction in which the second insertion portion 7b is inserted into the slider 5. Thus, as long as it has the same features as described above, the same effects as described above can be obtained. Here, even by the above-described abutment at at least one portion, it does not prevent the second insertion portion 7b from being displaced in the same direction as the direction in which the second insertion portion 7b enters the slider 5, and the accompanying rotation of the second base portion 6b.
[0093] The magnetic axis MA1 of the magnet (not shown) embedded in the first base portion 6a extends not along the vertical direction but along the horizontal direction. Similarly, the magnetic axis MA2 of the magnet (not shown) embedded in the second base portion 6b extends along the horizontal direction. That is, the first base portion 6a and the second base portion 6b are not magnetically joined and overlapped in the vertical direction, but are magnetically joined and arranged adjacent to each other in the horizontal direction. In addition, in association with this, the first insertion portion 7a is inserted not from the rear of the slider 5 but from the side of the slider 5.
[0094] The first base portion 6a is a substantially cylindrical member, and a pair of grooves 81, 82 are recessed in its circumferential surface. The second base portion 6b includes a disk portion and a pair of arms 83, 84 erected from its outer peripheral portion. Corresponding to the magnetic joining of the first base portion 6a and the second base portion 6b, the arm 83 is inserted into the groove 81 and fitted through the above-described abutting state. Similarly, the arm 84 is inserted into the groove 82 and fitted through the above-described abutting state. The first base portion 6a is held between the arms 83, 84.
[0095] Figure 18 is along Figure 17Schematic cross-sectional view of the dash-dotted line X18-X18. The first abutting portion 61 protrudes radially outward with respect to the magnetic axis MA1. The second abutting portion 62 protrudes radially inward with respect to the magnetic axis MA2. The first abutting portion 61 and the second abutting portion 62 protrude along an axis orthogonal to the direction in which the first base portion 6a and the second base portion 6b are magnetically joined. The first abutting portion 61 can include a contact surface extending along the magnetic axis MA1 and a contact surface disposed in a plane orthogonal or intersecting the magnetic axis MA1. Similarly, the second abutting portion 62 can include a contact surface extending along the magnetic axis MA2 and a contact surface disposed in a plane orthogonal or intersecting the magnetic axis MA2.
[0096] Refer to Figures 19 to 22 Another modification will be described. This modification is the same as the Figures 13 to 15 modification shown, and the first abutting portion 61 and the second abutting portion 62 are assigned to the inclined portion and the sliding portion, but are provided at different positions. In this case, the same effect can be obtained within the scope not conflicting with the above description. In addition, as an Figures 13 to 15 addition or substitution of the method or feature shown, the method or feature according to this modification can be adopted. In the case of adopting both of these methods or features, the rotational stability of the second base portion 6b can also be improved. In addition, if necessary, the inclined portion 31 and the inclined portion 31' are distinguished and named as the first inclined portion and the second inclined portion. The same applies to the sliding portion.
[0097] As Figure 19 and Figure 20 shown, the first base portion 6a has a sliding portion 32', and the second base portion 6b has an inclined portion 31'. Similar to the above various methods, corresponding to the magnetic attraction forces of the magnets M1 and M2, the sliding portion 32' slides on the inclined surface 31a' of the inclined portion 31', and just after the sliding portion 32' finishes sliding on the inclined surface 31a', the inclined portion 31' and the sliding portion 32' become in an abutting state (refer to Figure 21 ), thereby preventing the second member 12 from being displaced in the direction of exiting from the slider 5. In addition, the inclined portion 31' (second inclined portion) and the inclined portion 31 (first inclined portion) are located at different positions in the circumferential direction, and preferably the inclined portion 31' has an inclination equal to or smaller than the inclination of the inclined portion 31 (first inclined portion). In addition, the inclination refers to the angle formed by the inclined surface with respect to the plane orthogonal to the magnetic axis (or the vertical direction). Similarly, the sliding portion 32' (second sliding portion) and the sliding portion 32 (first sliding portion) are located at different positions in the circumferential direction.
[0098] Preferably, an intermediate surface 31c having a slope greater than that of the inclined surface 31a' is formed between the inclined surface 31a' and the restraining surface 31b'. The intermediate surface 31c can be a flat surface or a curved surface. As with the inclined surface 31a' and the intermediate surface 31c, inclined surfaces with a gradually increasing slope along the circumferential direction are provided in the inclined portion 31', whereby the displacement of the sliding portion 32' in the direction opposite to that of Figure 21 the example shown becomes smoother, making it easier to separate the first member 11 and the second member 12. Frankly speaking, it is possible to prevent an undesired relative displacement between the first member 11 and the second member 12 when they are connected (typically, just before the operation for the slider to advance), and it is also possible to make the expected separation of the two smoother when the connection between the first member 11 and the second member 12 is released.
[0099] Refer to Figures 23 to 26 Another modified example will be described. In this modified example, the first abutting portion 61 and the second abutting portion 62 are assigned to the protrusion 85 and the outer peripheral portion (or its peripheral wall) of the groove 86 that houses the protrusion 85. In this case, the same effect can also be obtained within the scope not conflicting with the above description. In addition, as an addition to or an alternative to the above various methods, this modified example can be adopted. Of course, it should be understood that there is no particular limitation on the portions where the protrusion 85 and the groove 86 are provided, and they can also be provided on the outer peripheral portion 66 of the first base portion 6a and the outer peripheral portion 69 of the second base portion 6b, respectively.
[0100] As Figures 23 to 25 shown, a protrusion 85 is formed on the lower surface (top surface) of the columnar portion 65 of the first base portion 6a. Correspondingly, a groove 86 is formed on the upper surface 68a of the bottom portion 68 of the second base portion 6b. The groove 86 has a depth sufficient to house the protrusion 85 and extends along the circumferential direction to allow its displacement. As Figure 26 shown, when the assembled state is established, the protrusion 85 abuts against the peripheral wall of the groove 86, that is, the first abutting portion 61 included in the protrusion 85 and the second abutting portion 62 included in the outer peripheral portion of the groove 86 are in an abutting state, whereby the same effect as above can be obtained.
[0101] Refer to Figure 27 A modified example of the inclined portion will be further described. As Figure 27 shown, the restraining surface 31b'' can form a first angle θ1 with respect to a line L1 parallel to the vertical direction or the magnetic axis. The inclined surface 31a' can form a second angle θ2 with respect to an axis L2 parallel to the vertical direction or the magnetic axis. Preferably, the first angle θ1 is smaller than the second angle θ2. More preferably, the first angle θ1 is 30° or less, 25° or less, or 20° or less. Thus, similarly to the above, the sliding portion 32' moves in the direction opposite to that of Figure 21The displacement in the opposite direction of the illustrated example becomes smooth, making it easy to separate the first member 11 and the second member 12. Additionally, as described above, it is possible to prevent an undesired relative displacement between the two when the first member 11 and the second member 12 are connected (typically, just before the operation for the slider to advance), and it is also possible to make the intended separation of the two smoother when the connection between the first member 11 and the second member 12 is released. Regarding the feature that the first angle θ1 is in an angular range of 30° or less, 25° or less, or 20° or less, it can be understood as a general feature applicable to all other embodiments disclosed in this specification (regardless of which of the first contact portion and the second contact portion it is).
[0102] For the sake of clarity, as an addition to or an alternative to the second contact surface 62c (for example, the restraining surface 31b), the first contact surface 61c can be made to have a vertical surface or an inclined surface. For example, in Figure 21 the case shown, the sliding portion 32' has a vertical surface that faces the inclined portion 31' side and contacts there, but this surface can also be made an inclined surface (for example, an angled surface similar to the above-mentioned restraining surface 31b").
[0103] Based on the above disclosure, those skilled in the art can make various changes to each embodiment and each feature. The reference numerals incorporated into the claims are for reference only and are not to be construed as limiting the claims.
