The present invention relates to a slide fastener, and in particular, relates to a slide fastener that can be opened reversely, in which two first and second sliders are arranged between the element rows of a pair of fastener stringers so that the rear opening sides thereof face each other.

2. Description of the Related Art Conventionally, a slide fastener that can be opened reversely is known in which two sliders are arranged between element rows of a pair of fastener stringers so that the rear opening sides face each other. For example, International Publication No. 2010/070743 (Patent) Reference 1) and the like. When such a slide fastener is used for opening and closing the left and right front bodies of clothes, when the upper first slider is moved upward, the space between the element rows of the left and right front bodies is closed, and when the first slider is moved downward, Open between element columns. Further, when the lower second slider is moved upward, the space between the element rows is opened, and when the second slider is moved downward, the space between the element rows is closed. When removing the clothing by opening the left and right front bodies completely, the second slider is generally at the lowest position corresponding to the box bar adjacent to the lower end of the element string of one of the left and right fastener stringers, and after the second slider A butterfly stick adjacent to the lower end of the element row of the other left and right fastener stringers in a state where the rear end side (lower end) of the first slider is abutted with the upper end (upper end) and the first and second sliders are aligned. Pull out through the element guide paths of the aligned first and second sliders. Thereby, the connection between the left and right fastener stringers is released. Conversely, when wearing clothes, the left and right fastener stringer's butterfly pins are inserted through the element guide paths of the first and second sliders aligned at the bottom. Accordingly, the left and right fastener stringers are connected to each other, and the first and second sliders can be opened and closed between the left and right fastener stringer element rows.

Yes, it took time and effort to connect the left and right fastener stringers or to release the connection between them.

International Publication No. 2010/070743

Therefore, an object of the present invention is to provide a slide fastener that can be aligned almost automatically after the first and second sliders are brought into contact with each other.

According to the present invention, a pair of fastener stringers each having an element row along the longitudinal direction, a first slider capable of opening and closing between the element rows of the pair of fastener stringers, and opening and closing between the element rows of the pair of fastener stringers And a second slider capable of abutting a rear opening side end of the second slider with a rear opening side end of the first slider, the first slider including a first body, A first handle connecting portion provided on the first body, a first handle rotatably connected to the first handle connecting portion in the longitudinal direction, and the first handle after the first slider. And an elastic member that urges in the direction of rotation to an initial position lying down on the mouth side, and the second slider includes a second body and an engagement portion, The first puller includes an engaged portion that can be engaged with the engaging portion of the second slider at the initial position in a state where rear end sides of the first and second sliders are in contact with each other. A slide fastener is provided.

The main parts of the first and second bodies of the first and second sliders and the first handle connecting portion (and the second handle connecting portion described later) are manufactured by die casting a metal such as an aluminum alloy or a zinc alloy. However, the present invention is not limited to this. The first puller (and the second puller described later) can be manufactured by die casting a metal such as an aluminum alloy or a zinc alloy, or by injection molding a resin such as a thermoplastic resin or a thermosetting resin.

In the present invention, the first puller connected to the first puller connecting portion in the first slider so as to be pivotable in the longitudinal direction is usually in an initial state in which the first slider is laid down on the rear opening side of the first slider due to the biasing of the elastic member. In position. When the user moves the first slider, if the user lifts the first puller from the initial position, the first puller turns from the lying down state and rises up against the biasing of the elastic member. When the user pulls the first handle from this state and moves the first slider to one side and the other side in the longitudinal direction, the element rows of the pair of fastener stringers are closed and opened. Thereafter, when the user releases his hand from the first puller, the first puller automatically falls down due to the bias of the elastic member and returns to the initial position. When releasing or linking a pair of fastener stringers, the second slider is positioned at the end position (generally the lowest position) corresponding to the box bar at one end in the longitudinal direction (generally the lower end) of the element string of one fastener stringer. Then, the first slider is moved to the second slider side by pulling the first handle, and the rear end of the first slider is abutted with the rear end of the second slider. When this matching is completed, the user releases his hand from the first puller. As soon as the user removes his hand from the first puller, the first puller falls to the initial position due to the bias of the elastic member, and at the same time the first puller returns to the initial position, the engaged portion of the first puller is second. The first and second sliders are automatically aligned by engaging with the engaging portion of the slider. In this aligned state, the butterfly bar adjacent to one end in the longitudinal direction of the element row of one fastener stringer can be smoothly pulled out or inserted through the element guide paths of the first and second sliders.

In the present invention, the user can move the second slider by directly picking the second body. However, in one embodiment of the present invention, the second slider is a second puller provided on the second body. A connection part and a 2nd handle connected with respect to the 2nd handle connection part are provided. In this form, the user can move the second slider by picking the second handle. In the present invention, the engaging portion of the second slider is, for example, a convex portion or a concave portion provided on the second body of the second slider, a convex portion or a concave portion provided on the second pull joint connecting portion or the second pull handle, or the like. In addition, a part or all of the second handle connecting portion can be the engaging portion of the second slider. As the form of the engaged portion of the second slider and the engaged portion of the first puller of the first slider, when the first puller of the first slider returns to the initial position where the first slider is lowered, Possible convex portions and concave portions or openings may be mentioned, but are not limited thereto.

In an embodiment of the present invention, the first puller can restrain the second puller in a state where the engaged portion is engaged with the engaging portion of the second slider. Here, “restraint” is a state in which the engaged portion of the first handle is engaged with the engaging portion of the second slider (engaged state), and the second handle is also in the width (left and right) direction in the front and back direction. It means that you don't hang around. The second slider is restrained by a) when the engaged first puller restrains the second puller regardless of the biasing by the elastic member, and b) when the engaged first puller is pressed by the elastic member. In some cases, the second handle is pressed and restrained by the force. In a state where the engaged portion of the first handle and the engaging portion of the second slider are engaged, when the second puller hangs in the front-back direction or the width direction with respect to the second puller connecting portion, the second puller Noise may be generated in contact with the first handle, the second body of the second slider, the second handle connecting portion, and the like, which may cause discomfort to the user. Such noise can be even more unpleasant, especially when the user is walking, exercising, and the like. In this embodiment, in the state where the first slider and the second slider are abutted and the engaged portion of the first handle at the initial position and the engaging portion of the second slider are engaged, By restraining the second puller, it is possible to suppress wobbling in the front and back direction, the width direction, and the like of the second puller. This eliminates the occurrence of the noise.

In one embodiment of the present invention, the engaged portion of the first handle is an opening or a recess. In this case, the engaging portion of the second slider becomes a convex portion that can be engaged with the opening or the concave portion, and the convex portion is provided on the second body, the second puller connecting portion, or the second puller of the second slider. It is possible, and a part or all of the second handle connecting part can be a convex part that can be engaged with the opening or the concave part. In another embodiment of the present invention, the engaged portion of the first handle is an opening or a recess capable of receiving the second handle connecting portion. In this case, the opening or recess of the first handle receives the second handle connecting portion of the second slider, and the opening or recess and the second handle connecting portion engage with each other.

In the present invention, when connecting or releasing a pair of fastener stringers, the user pulls the first handle to move the first slider, and the rear opening side end of the first slider corresponds to the box bar. As soon as the user lifts his / her hand from the first puller after butting the rear end of the second slider at the end position, the first puller falls to the initial position by the bias of the elastic member, and the first puller As soon as the position returns to the initial position, the engaged portion of the first handle engages with the engaging portion of the second slider. As a result, the first and second sliders are aligned. Since the first and second sliders are almost automatically aligned just by abutting the first and second sliders in this way, the connection and disconnection between the pair of fastener stringers is simplified.

It is defined on the upper surface of the plate 41a. The second handle connecting portion 42 has one end portion 42a connected to the rear opening 40b side on the upper surface of the upper wing plate 41a, the other end portion 42b connected to the guide column 41c side on the upper surface of the upper wing plate 41a, and one end It is formed in a bridge shape from an intermediate part 42c that connects the part 42a and the other end part 42b. In the present embodiment, the engaging portion of the second slider 40 is a second pulling joint portion 42 that can be said to be a convex portion protruding upward from the upper surface of the upper blade 41a. As will be described in detail later, the opening 33 of the first handle 30 of the first slider 20 described above is in the initial position in a state where the rear ends 20b and 40b side ends of the first and

second sliders

20 and 40 are in contact with each other. The second handle connecting portion 42 of the second slider 40 can be engaged with the second handle connecting portion 42 (see FIGS. 12 to 14). The outer surface of the second handle connecting portion 42 (the surface facing away from the handle connecting hole 43) is a curved surface that protrudes outward in the lateral direction and the longitudinal direction.

The second puller 50 includes a base-end-side connecting part 51 connected to the second pulling-connecting part 42, and a knob 52 that a user picks and extends from the connecting part 51 to the free end side while expanding the left-right width. . The second handle 50 has a shaft-like base end portion 50 a that is passed through the handle connection hole 43 of the second handle connection portion 42. The connecting portion 51 has a substantially rectangular connecting hole 51a through which the second handle connecting portion 42 is passed. The knob 52 has an elliptical knob hole 52a that is long in the left-right direction. The picking hole 52a plays a role of making it easy for the user to pick the picking part 52. The second puller 50 passes the base end part 50a through the puller connecting hole 43 of the second puller connecting part 42 and passes the second puller connecting part 42 through the connecting hole 51a, thereby making the second puller connecting part 42 with respect to the second puller connecting part 42. Connected. The second puller 50 connected to the second puller connecting part 42 can rotate about 180 degrees in the longitudinal direction about the base end part 50a on the second body 41 (the arrow in FIG. 10).

The second handle 50 is restrained by pressing the connecting portion 51 of the second handle 50 against the upper surface of the upper blade 41a of the second fuselage 41 by urging. However, the present invention is not limited to this, and includes a mode in which the first puller 30 restrains the second puller 50 irrespective of the biasing force by the spring 24 in the engaged state.

When releasing the connection of the left and right stringers 10 </ b> A and 10 </ b> B, the second slider 40 is positioned at the lowermost position, and the first slider 20 is abutted against the second slider 40. As described above, as soon as the first slider 20 is brought into contact with the second slider 40 and the user releases the hand from the first puller 30, the first and

second sliders

20 and 40 move to the opening 33 and the second puller of the first puller 30. The connecting portion 42 is engaged, and the first and second sliders are brought into butt engagement. In this state, the first and

second sliders

20 and 40 are properly aligned. In this aligned state, the left stringer 10A side butterfly pin (not shown) is pulled out through the element guide paths 20c and 40c of the first and

second sliders

20 and 40, thereby connecting the left and

right stringers

10A and 10B. Is released. When the left and

right stringers

10A and 10B are connected, the butterfly of the left stringer 10A is placed after the first and

second sliders

20 and 40 are brought into butt engagement at the lowermost position of the right stringer 10B. The rod is inserted through the element guide paths 20c, 40c of the first and

second sliders

20, 40. As a result, the left and

right stringers

10A and 10B are connected.

In the above embodiment, the example in which the engaging portion of the second slider 40 is the second pull coupling portion 42 has been described. However, the present invention is not limited to such an embodiment, and will be described next. In addition, the second slider includes a form in which the second handle connecting portion and the second handle are not provided. FIG. 14 is a perspective view similar to FIG. 12 showing a butt engagement state of the first slider 20 and the second slider 60 which is a modified example of the second slider. The second slider 60 can be used in the slide fastener 1 according to the present invention instead of the second slider 40 described above. The second slider 60 includes a second body 61 having upper and

lower blades

61a and 61b and a guide post 61c, and a raised portion 62 as an engaging portion that protrudes from the upper surface of the upper blade 61a of the second body 61. The second body 61 has substantially the same form as the second body 41 of the second slider 40, and therefore, the second body 61 is opened at two shoulder openings and one rear opening similarly to the second body 41. Y-shaped element guide path. The raised portion 62 has an external shape that fills the handle connecting hole 43 of the second handle connecting portion 42 of the second slider 40. Therefore, the raised portion 62 can be engaged with the opening 33 of the first puller 30 by the operation in which the first puller 30 of the first slider 20 returns to the initial position when the first and second sliders 20 and 60 are in contact with each other.
