Description

Slide fastener with separable rear stop

Technical Field

The present invention relates to a slide fastener with separable bottom stops at ends of right and left fastener tapes, and more particularly, to a slide fastener having a separable bottom stop. The separable backstop includes a fitting body and a pivot stopper body, and has a structure capable of engaging the fitting body with the pivot stopper body in accordance with two modes of an engaging operation.

Background

Conventionally, as a separable bottom end stop of a slide fastener, there is known an open-sided separable bottom end stop which allows mating bodies formed on a pair of right and left fastener stringers to be inserted from a side of an engaging body and engaged with an engaging body formed on the other fastener stringer without passing the mating bodies through element guide passages in a slider. In addition, for example, Japanese Utility model application publication (JP-Y) No.59-25227 has disclosed an invention relating to such a side open type separable rear end stop.

In the open-sided separable bottom end stop disclosed in JP-Y-59-25227, the coupling body and the engaging body of the separable bottom end stop are fixed to the ends of the left and right element rows so that they oppose each other. The joint body includes: a slider holding portion formed on front and rear surfaces of the fastener tape to hold the slider; a fitting portion formed thicker than the slider holding portion on a tape end side of the slider holding portion and engaged with the fitting body; a groove formed in a side surface of the slider holding portion and an inner side surface of the fitting portion; and a protruding portion protruding from a middle portion of the groove. The fitting portion includes a support hole formed in an inverted L shape from a side surface on the fitting body side toward a center portion of the fitting portion so that it passes through front and rear surfaces of the fitting portion, the support hole having an inverted C shape as shown in a front view thereof.

The fitting body has a fitting plate portion having a thickness fitted into the groove included in the engaging body, and a recessed portion provided on the engaging body side surface of the fitting plate portion and having a shape corresponding to the protruding portion. The band end side of the fitting plate portion is provided with an expanded portion thicker than the fitting plate portion. The expansion portion has support pins protruding to the front and rear surfaces of the belt.

The left and right fastener stringers in the slide fastener with the side open type separable back stop having the above-described configuration are closed as follows. After the slider is slid to a position where it comes into contact with the mating portion of the engaging body and comes into contact therewith, the support pin of the mating body is inserted into the support hole in the engaging body. At this time, the support pin of the engaging body is stably supported at the end of the support hole because the engaging portion of the engaging body has an inverted C-shape. Next, the engaging body, the support pin of which is inserted into the support hole, is rotated about the support pin toward the engaging body, and thus, the engaging plate portion of the engaging body is inserted into the slider through the interval between the upper and lower flanges of the slider. Therefore, the left and right element rows are positioned so as to enable stable engagement. Thereafter, by sliding the slider in the element engaging direction (by pulling upward), the left and right element rows are engaged with each other so as to close the slide fastener.

The separating operation in the slide fastener with the open-sided separable bottom end stop is performed as follows. The slider slides toward the separable rear stop and comes into contact with the mating portion of the engaging body, and then the mating body is rotated about the support pin in a direction away from the engaging body. Therefore, the engagement plate portion of the engagement body is detached from the slider. In addition, when the support pin of the mating body is pulled out from the support hole in the engaging body, the left and right fastener stringers are separated from each other.

The slide fastener with the side-open type separable rear end stop has the following advantageous effects. The left and right fastener stringers may be positioned and separated by inserting the support pin of the fitting body into the support hole formed in the coupling body to rotate the fitting body or by pulling the support pin inserted into the support hole out of the coupling body. Therefore, the above-mentioned slide fastener does not require an operation of inserting the insert pin through the inside of the slider when the insert pin is incorporated into the box of the slide fastener with a general separable back stop including the insert pin, the box pin (box pin), and the box. This improves the operability of the separable bottom end stop so that the left and right fastener stringers can be closed or separated very easily.

Therefore, the open-sided separable rear stop can be applied, for example, to products in which the zipper operation needs to be completed with a single hand, products in which the zipper operation needs to be fumbling since the position of the separable rear stop cannot be directly determined, or products in which the zipper operation needs to be completed in an environment unsuitable for precision work.

The side open type separable bottom end stop described in JP-Y-59-25227 allows the closing operation and the separating operation of the slide fastener to be performed more easily than the conventional separable bottom end stop including the insert pin, the box pin and the box, and its practical utility is excellent. However, in terms of the operation method for engagement and withdrawal, the open-sided separable backstop is completely different from the ordinary separable backstop including a latch or the like, and cannot be confirmed or clearly understood by the user.

Therefore, although the slide fastener having the open-sided separable bottom end stop is easy to perform the closing or separating operation, users who are accustomed to the ordinary separable bottom end stop having the plug pin or the like often feel troublesome in operating the open-sided separable bottom end stop. Therefore, before a user is accustomed to the operation of the open-sided separable rear stop, the user often tries to insert the mating body into the slider when engaging the mating body with the coupling body, or often tries to pull the mating body toward the slider by force when pulling the mating body out of the coupling body. For this reason, the practicality thereof is further deteriorated.

Disclosure of Invention

The present invention has been made in view of the conventional problems, and it is an object of the present invention to provide a slide fastener with a separable bottom end stop which can be conveniently used by everyone, and allows a user to perform a closing operation and a separating operation by improving the ease of use of the separable bottom end stop.

In order to achieve the above object, according to the present invention, there is provided a slide fastener with a separable bottom end stop, comprising: a slider through which element rows are passed, wherein the element rows are mounted on opposite side edges of a pair of left and right fastener tapes; and a separable bottom stop including a fitting body provided at an end portion of the element row of one of the fastener tapes and having a portion to be pivoted, and a pivoting stopper body provided at an end portion of the element row of the other fastener tape, engageable with or disengageable from the portion to be pivoted of the fitting body, and functioning as a bottom stop of the slider. The slider has a guide post, an upper shell plate and a lower shell plate connected by the guide post, a flange portion erected from left and right side edges of the upper shell plate and/or the lower shell plate, and a Y-shaped element guide passage surrounded by the upper shell plate, the lower shell plate, and the flange portion and divided into two parts by the guide post from a rear opening of the slider to a toe opening. The pivoting stopper body has a pivoting stopper portion which is capable of being rotationally engaged with the portion to be pivoted by fitting the portion to be pivoted into the pivoting stopper portion from a side portion of the pivoting stopper body, and which is capable of being rotationally engaged with the portion to be pivoted by inserting the portion to be pivoted into the pivoting stopper portion from a toe opening of the slider through the element guide passage; the thickness of the portion to be pivoted is formed to be smaller in a direction from the front surface to the rear surface of the fastener tape than a pitch in a height direction of the element guide passage in the slider.

In the slide fastener with the separable back stop of the present invention, preferably, the fitting body has a thin fitting plate portion which is integrally formed on the front and rear surfaces of one of the fastener tapes and has a portion to be pivoted arranged at a tape end side front portion of the fitting plate portion; and the pivoting stopper body has a slider holding portion integrally formed on front and rear surfaces of the other fastener tape to hold the slider. The pivot stopper portion is formed so as to be increased in thickness on the tape end side of the slider holding portion by the step portion; the pivot stopper portion includes a substantially J-shaped inner face that extends from the slider holding portion to the tape end side and is bent toward the mating body side, and a pivot space that allows the portion to be pivoted to be fitted into the substantially J-shaped inner face from a side portion of the pivot stopper body; and the pivot stop portion is capable of engaging the portion to be pivoted to the generally J-shaped inner face. The thickness of the portion to be pivoted in the tape front-rear surface direction is set smaller than the pitch of the slider in the element guide passage height direction, and the thickness of the engaging plate portion is set smaller than the pitch of the gap provided on the flange portion of the slider.

In the slide fastener of the invention, preferably, the portion to be pivoted has a cylindrical pivot shaft provided to project from the mating plate portion in the tape front and rear surface directions. The portion to be pivoted is formed in a circular shape so that it is flush with the front and rear surfaces of the fitting plate portion.

In the present invention, it is preferable that a fitting plate portion engaging groove that allows the fitting plate portion to be fitted therein is formed in a side face of the slider holding portion opposite to the fitting plate portion. Further, it is preferable that the fitting plate portion engaging groove is formed in a part of the substantially J-shaped inner face of the pivot stopper portion.

In addition, a to-be-pivoted portion engagement groove into which the to-be-pivoted portion is allowed to be fitted is formed in a substantially J-shaped inner face of the pivot stopper portion, and the to-be-pivoted portion engagement groove constitutes a pivoting space.

Preferably, the pivot stopper portion has a slit passing from the inner face of the substantially J-shape to the outer peripheral face, and the slot width of the slit is set larger than the thickness of the fitting plate portion. It is also preferable that the fitting plate portion has a notch portion cut out from the belt end side of the fitting plate portion toward the belt inner side.

In the slide fastener with the separable back stop of the present invention, as described above, the pivot stopper body of the separable back stop has the pivot stopper portion which can engage the portion to be pivoted of the mating body by fitting the portion to be pivoted of the mating body from the side of the pivot stopper body and can engage the portion to be pivoted of the mating body by inserting from the element opening of the slider through the element guide passage. In the slide fastener of the invention, the mating body is inserted into the element guide passage through the flange portion of the slider in a state where the slider is held on the pivot stopper body and the portion to be pivoted of the mating body is engaged with the pivot stopper body. Thereafter, the left and right element rows are engaged with each other by sliding the slider. Thus, the slide fastener of the present invention is configured to be capable of performing two different joining operations. The operation includes a first engaging operation of engaging the to-be-pivoted portion of the fitting body with the pivot stopper body by fitting it in from a side portion of the pivot stopper body, and a second engaging operation of engaging the to-be-pivoted portion of the fitting body with the pivot stopper body by inserting it into the element guide passage of the slider.

In the conventional slide fastener with the separable bottom end stop, the separable bottom end stop is formed to perform only one engaging operation and disengaging operation, and therefore, the separable bottom end stop cannot be engaged or disengaged by two different operations. In general, it has not been thought to construct a separable backstop that enables engagement or disengagement of the separable backstop by two operations.

In contrast, the slide fastener with the separable bottom end stop of the present invention is constructed as follows. That is, not only can the portion to be pivoted of the mating body of the conventional open-sided separable rear end stop be engaged with the pivot stopper portion by being loaded from the side of the pivot stopper portion, but also, similarly to the ordinary separable rear end stop having the latch or the like, the portion to be pivoted of the mating body can be engaged with the pivot stopper portion by being inserted into the element guide passage from the element opening of the slider. Therefore, a user using the slide fastener with the separable bottom end stop of the present invention can freely select the first coupling operation and the second coupling operation to couple the mating body with the pivot stopper body so as to close the slide fastener.

It is assumed that when using the slide fastener with the separable bottom end stop of the present invention, the user is not used to operate the side open type separable bottom end stop. In this case, the second engaging operation of engaging the portion to be pivoted of the mating body with the pivot stopper portion by inserting into the slider is performed, so that he/she can smoothly close the slide fastener without any trouble in operating the separable bottom end stop. In addition, when he/she is accustomed to or becomes accustomed to operating the open-sided separable rear end stop, a first engaging operation of engaging the portion to be pivoted of the mating body with the pivot stop portion by being loaded from the side of the pivot stop body is performed, so that he/she can easily close the slide fastener.

When separating the slide fastener, the user can freely select any one of two different operations for pulling out the separation end stop as in the joining operation. Therefore, the slide fastener with the separable bottom end stop of the present invention is improved in ease of use of the separable bottom end stop and is excellent in practicality and operability, so that a person can easily operate the slide fastener of the present invention, as compared with a conventional slide fastener with an open-sided separable bottom end stop or a slide fastener with a general separable bottom end stop including a plug or the like.

In the slide fastener with the separable bottom end stop of the present invention, the fitting body is formed on the front and rear surfaces of the fastener tape and has a thin fitting plate portion in which the portion to be pivoted is arranged at the tape end side front end portion. The pivoting stopper body has a slider holding portion and a pivoting stopper portion integrally formed on front and rear surfaces of the fastener tape, and the pivoting stopper portion has a substantially J-shaped inner face and a pivoting space that allow portions of the mating body to be pivoted to be rotatably engaged. The thickness of the portion to be pivoted in the front-rear surface direction is set smaller than the height of the element guide passage of the slider, and the thickness of the fitting plate portion is set smaller than the pitch of the gap provided on the flange portion of the slider. Since the fitting body and the pivot stopper body of the present invention have the above-described configurations, the slide fastener of the present invention can secure a structure which engages the portion to be pivoted of the fitting body with the pivot stopper body by the above-described two different engaging operations and disengages the portion to be pivoted of the fitting body by the two different disengaging operations.

Since the portion to be pivoted has the cylindrical pivot shaft provided projecting from the fitting plate portion according to the present invention, the portion to be pivoted can be stably engaged with the pivot stopper portion by being fitted from the side of the pivot stopper body when the first engaging operation is performed. In addition, the engaging body can smoothly rotate about the pivot shaft toward the pivot stopper. When the second engaging operation is performed, the portion to be pivoted can be stably engaged with the pivot stopper portion by being inserted into the slider.

Instead of having a cylindrical pivot shaft provided so as to protrude from the fitting plate portion, the portion to be pivoted may have a structure formed circularly so that it is flush with the front and rear surfaces of the fitting plate portion. When the first engaging operation is performed, the portion to be pivoted having such a configuration can be engaged by being fitted from the side of the pivot stopper body, and further, freely rotated about the portion to be pivoted toward the pivot stopper body. Also, when the second engaging operation is performed, the portion to be pivoted can be stably engaged with the pivot stopper portion by insertion.

In the present invention, the fitting plate portion engaging groove is formed in a side face of the slider holding portion opposite to the fitting plate portion, and in addition, the fitting plate portion engaging groove is also formed in a part of the substantially J-shaped inner face of the pivot stopper portion. When the fitting body is engaged with the pivot stopper, the fitting plate portion can be stably guided to a predetermined position of the pivot stopper by fitting the fitting plate portion of the fitting body into the fitting plate portion engaging recess. When the slide fastener is closed, the coupling state between the mating body and the pivot stopper can be stably maintained. For this reason, even if the separable rear stop receives a force (an upward pushing force) in the tape front and rear surface direction in the state where the slide fastener is closed, the engaging bodies of the separable rear stop can be prevented from being disengaged from the pivot stopper, thereby stably maintaining the engaged state. Meanwhile, the fitting plate portion engaging groove may be formed continuously or intermittently on a side face of the slider holding portion opposite to the fitting plate portion and a part of the substantially J-shaped inner face of the pivot stopper portion.

A to-be-pivoted portion engagement groove, which allows the to-be-pivoted portion to fit therein and constitutes a pivoting space, is formed in the substantially J-shaped inner face of the pivot stopper portion. With this configuration, when the first and second engaging operations are performed, the fitting body can be reliably engaged with the pivot stopper body, so that the engaged state can be stably maintained.

In addition, the slit is formed so as to pass from the substantially J-shaped inner face of the pivot stopper portion to the outer peripheral face and/or the notch portion is formed in the fitting plate portion. Thus, when the fitting body is engaged by being fitted from the side of the pivot stopper body, interference between the fitting body and the pivot stopper body can be prevented, thereby smoothly completing the engaging operation of the separable rear stop.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the respective embodiments described below, but may be modified in various ways as long as it has substantially the same configuration as the present invention, performs similar operations, and obtains similar effects. In the embodiments, a slide fastener has been described in which its elements and separable bottom end stop are formed by injection molding a synthetic resin. However, the present invention is not limited to this example, and a slide fastener having a spiral element or a metallic separable back stop on its fastener tape may be employed.

(first embodiment)

Fig. 1 is a perspective view of a main part of a separable back stop mounting portion of a slide fastener with a separable back stop according to a first embodiment of the present invention. In the following description, in order to explain the present invention to facilitate understanding thereof, on the basis of the slide fastener 1 shown in fig. 1, a direction in which the slider 30 is slid in the longitudinal direction of the fastener tape so as to close the slide fastener 1 is designated as forward, and a direction in which the slider 30 is slid so as to separate the slide fastener 1 is designated as backward. In addition, if the slide fastener 1 is viewed from the front, the side of the fitting body 10 in the width direction of the fastener tape 2 where the separable back stop 5 is formed is designated as the left side, and the side where the pivot stopper body 20 is formed is designated as the right side.

As shown in fig. 1, a slide fastener 1 with a separable bottom end stop of the first embodiment includes a pair of right and left fastener tapes 2, elements 3 arranged in rows on opposite side edges of the right and left fastener tapes 2, a separable bottom end stop 5 provided at one end of the element row 4, and a slider 30 (not shown in fig. 1).

The fastener tape 2 has core thread portions 7 on opposite side edges thereof, and a plurality of elements 3 are arranged at prescribed intervals along an element mounting edge including the core thread portions 7 of the fastener tape 2 so as to form an element row 4. The fastener elements 3 are composed of a body portion to be fixed to the fastener tape 2, a neck portion projecting outward from the body portion, and an expanded coupling head provided at a front end of the neck portion. Conventionally, the fastener element 3 can be attached to the fastener tape 2 by injection molding a general synthetic resin material such as polyacetal into a predetermined shape.

For the slider 30, a generally known type can be used. The slider 30 includes, for example, an upper case plate 31 a; a lower shell plate 31 b; upper and lower flanges 32a, 32b vertically arranged along left and right ends of the upper and lower case plates 31a, 31 b; a guide post 33 erected to couple a front end side center portion of the upper shell plate 31a and a front end side center portion of the lower shell plate 31 b; and a pull tab 34 attached to the upper shell plate 31 a. The slider 30 has a rear opening located on the rear end side thereof and leg openings located on the left and right sides of the guide post 33 on the front end side of the slider 30. An element guide passage 35 surrounded by the upper and lower flanges 32a, 32b and the upper and lower shell plates 31a, 31b is formed inside the slider 30. The element guide passage 35 is branched into two by the guide post 33 so that it extends through the inside of the slider 30 from the rear opening to the element foot opening in a letter Y shape. In the slider 30 of the present invention, the flanges may stand on the left and right side edges of either the upper shell plate 31a or the lower shell plate 31 b.

The separable back stop 5 has a fitting body 10 and a pivoting stopper body 20 made of synthetic resin so that they are formed continuously from the fastener element rows 4 at the bottom ends of the right and left fastener tapes 2.

The fitting body 10 is composed of a thin fitting plate portion 11 formed integrally on the front and rear surfaces of one fastener tape 2 (left side), a portion to be pivoted 12 formed at the fastener tape end side front end portion (rear end portion) of the fitting plate portion 11, a projecting portion 13 formed along the fastener tape inner side edge of the fitting plate portion 11, a coupling portion 14 formed continuously from the fastener element row 4 located at the front end portion of the fitting plate portion 11, and a recessed portion 15 formed at the front and rear surface portions corresponding to the core wire portion 7 of the fitting plate portion 11.

In the first embodiment, a tape end portion of the left side fastener tape 2 having the fitting body 10 is partially cut away, and a fitting plate portion 11 is provided at a notch portion of the fastener tape 2 so as to extend rearward. The fitting plate portion 11 is flat on both the front and rear surfaces except the recessed portion 15, and the tape thickness in the direction from the front surface toward the rear surface is set smaller than the interval of the gap formed between the upper and lower flanges 32a, 32b of the slider 30. The mating panel portion 11 has a notched portion 16 which is cut (forward) from the fastener tape end side into the fastener tape.

The portion-to-pivot 12 has a cylindrical pivot shaft 12a that protrudes from the front and rear surfaces of the fitting plate portion 11 at the extended portion of the fitting plate portion 11. The thickness of the pivot shaft 12a in the direction from the front surface to the rear surface of the fastener tape is smaller than the interval in the height direction of the element guide passage 35 inside the slider 30, that is, the interval between the upper case plate 31a and the lower case plate 31b of the slider 30, and the thickness of the pivot shaft 12a in the direction from the front surface to the rear surface of the fastener tape is larger than the interval between the upper and lower flanges 32a, 32 b.

The protruding portion 13 is thicker than the fitting plate portion 11. Since the thick projecting portion 13 is formed along the inner side edge of the fastener tape, the strength of the fitting body 10 is improved. In addition, the engaging body may be formed in a shape that can be easily grasped by a user who operates the separable rear stop 5.

The concave portion 15 can be stably formed in the fitting body 10, and it is formed at a position corresponding to the core wire 7 so as to make the fitting plate portion 11 flat. More specifically, the core thread portion 7 of the fastener tape 2 is thicker than the fastener tape 2. For this reason, when the flat fitting portion 11 is formed by molding synthetic resin at the site where the core wire portion 7 is formed, the fitting plate portion 11 formed on the core wire portion 7 is extremely thin. If the thickness of the fitting plate portion 11 is locally reduced, it is recognized that a defect such as deterioration of resin flow at the thin portion of the fitting plate portion 11 or failure to obtain sufficient strength is generated when the fitting body 10 is injection molded. However, if the concave portion 15 is formed, the thin portion formed in the fitting plate portion 11 is reduced. Therefore, the occurrence of the above-described defects can be effectively prevented.

The pivot stopper body 20 of the separable back stop 5 includes a slider holding portion 21, a pivot stopper portion 23, a reinforcing portion 25, a mating plate portion engaging groove 26, and a slit 27. A slider holding portion 21 is formed on the front and rear surfaces of the other fastener tape 2. The pivot stopper portion 23 is formed thicker than the slider holding portion 21 by the step portion 22, and has a substantially J-shaped inner face 24 and a pivot space 28. A reinforcing portion 25 is formed inside the fastener tape with respect to the slider holding portion 21 so as to increase the strength of fixing the pivoting stopper body 20 to the fastener tape 2. A fitting plate portion engaging groove 26 is formed on a side surface of the slider holding portion 21 opposite to the fitting plate portion 11 and a part of the substantially J-shaped inner face 24. The slit 27 penetrates from the substantially J-shaped inner face 24 to the outer peripheral face of the pivot stopper portion 23. Meanwhile, depending on the shape of the mating plate portion 11, the mating plate portion engagement groove 26 may be formed only on the side of the slider holding portion 21 opposite to the mating plate portion 11 because the mating plate portion engagement groove 26 is engaged with the mating plate portion 11 of the mating body 10 when the slide fastener 1 is closed.

The thickness of the slider holding portion 21 in the direction from the front surface to the rear surface of the fastener tape is smaller than the height of the element guide passage 35 inside the slider 30 and larger than the gap between the upper and lower flanges 32a, 32 b. An intermediate portion 21a of a side of the slider holding portion 21 opposite to the mating body is bent so that it slightly expands toward the mating body 10. In addition, when the slider 30 is brought into contact with the step portion 22 by sliding as described later (see fig. 2), the slider holding portion 21 holds the slider 30 so that it can be inserted into the element guide passage 35 in the slider 30.

In the first embodiment, the pivotal stop portion 23 is thicker than the slider holding portion 21 by the step portion 22 and extends from the slider holding portion 21 to the fastener tape end portion, so that the pivotal stop portion 23 is formed to be bent from the fastener tape end portion toward the fitting body 10 side. Thus, the pivot stopper portion 23 has a substantially J-shape as shown in a plan view. The pivot stop portion 23 includes a pivot space 28 and a generally J-shaped inner face 24. The pivot space 28 is opened upward so that the portion to be pivoted 12 of the fitting body 10 can be fitted from the side of the pivot stopper body 20. The substantially J-shaped inner face 24 holds the portion-to-be-pivoted 12 fitted into the pivoting space 28 in contact therewith so that the portion-to-be-pivoted 12 is rotatably engaged. A substantially J-shaped inner face 24 extends from the slider holding portion 21 to the fastener tape end side and is bent toward the fitting body 10 side. The radius of curvature of the curved portion within the generally J-shaped inner face 24 is generally equal to the radius of the portion 12 of the mating body 10 to be pivoted.

A slit 27 is formed on the curved portion side front end 23a of the pivot stopper portion 23 so that it passes through the outer peripheral surface of the pivot stopper portion 23 from the substantially J-shaped inner face 24. The width of the slit 27 from the fastener tape front surface toward the rear surface is larger than the thickness of the engagement plate portion 11 to allow the engagement plate portion 11 of the engagement body 10 to be inserted therein.

Next, the operation of closing/separating the slide fastener 1 of the first embodiment having the separable bottom end stop 5 as described above will be described.

First, a first engaging operation of engaging the fitting body 10 of the separable back stop 5 with the pivot stopper body 20 by loading from the side of the pivot stopper body 2 at the time of closing the slide fastener 1 will be described.

The first joining operation is performed as follows. First, as shown in fig. 2, the slider 30 slides toward the pivoting stopper body 20 mounted on the other (right) fastener stringer 6', and comes into contact with the step portion 22 as the back stop. This operation allows the slider 30 to be held by the slider holding portion 21. Meanwhile, in fig. 2 and later-described fig. 3, 5, 8, the slider 30 is indicated by a two-dot chain line, and the engagement groove of the engagement plate portion and the slit of the pivot stopper portion are indicated by a broken line.

Next, the portion-to-be-pivoted 12 of the fitting body 10 mounted on the one-side (left-side) fastener stringer 6 is fitted from the side portion of the pivot stopper body 20 through the gap formed between the pivot stopper portion 23 and the slider 30 in the right direction from the left side of the pivot stopper body 20 to the pivot stopper portion 23. Thus, the part 12 to be pivoted can be introduced into the pivot stop portion 23 of the pivot stop body 20 and brought into contact with the substantially J-shaped inner face 24. In the slide fastener 1 of this first embodiment, the notch portion 16 is formed in the fitting plate portion 11 of the fitting body 10, and the slit 27 is formed in the bent portion side front end 23a of the pivot stopper portion 23. A notch portion 16 is formed by cutting a left side area of the portion to be pivoted 12 upward from an end portion of the fastener tape 2, and the fastener tape 2 within the forming area of the notch portion 16 is also cut off so that no fastener tape 2 protrudes in the notch portion 16. Therefore, the fitting plate portion 11 and the pivot stopper portion 23 do not interfere with each other, so that the portion-to-be-pivoted 12 can be smoothly guided from the side of the pivot stopper portion 23, and therefore, the operation of fitting the portion-to-be-pivoted 12 into the pivot stopper portion 23 can be easily performed.

The portion to be pivoted 12 is engaged with the pivot stopper portion 23 of the pivot stopper body 20, and then, the fitting body 10 is rotated about the portion to be pivoted 12 toward the pivot stopper body 20. As shown in fig. 3, the engagement plate portion 11 of the engagement body 10 is inserted between the upper and lower flanges 32a, 32b of the slider 30 until it comes into contact with the guide post 33 or it approaches the guide post 33. Therefore, the left and right element rows 4 are positioned so as to enable stable coupling.

Thereafter, the slider 30 is slid upward in a state where the engagement plate portion 11 is inserted into the element guide passage 35 through the upper and lower flanges 32a, 32 b. Thus, as shown in fig. 4, the fitting plate portion 11 of the fitting body 10 can be fitted into the fitting plate portion engaging groove 26 of the fitting body 20, and at the same time, the right and left element rows 4 can be coupled to each other so as to close the slide fastener 1.

Next, a second engaging operation of engaging the mating body 10 of the separable back stop 5 with the pivot stopper body 20 by inserting the pivot stopper body 20 through the element guide passage 35 of the slider 30 when closing the slide fastener 1 will be described.

The second joining operation is performed as follows. First, similarly to the first engaging operation, the slider 30 slides toward the pivoting stopper body 20 mounted on the right side fastener stringer 6', and comes into contact with the step portion 22. This operation allows the slider 30 to be held by the slider holding portion 21. At this time, a space through which the portion to be pivoted 12 of the fitting body 10 is allowed to pass is formed between the upper and lower flanges 32a, 32b on the fitting body 10 side of the slider 30 and the slider holding portion 21 of the pivoting stopper body 20 (see fig. 5).

Subsequently, the portion-to-be-pivoted 12 of the fitting body 10 mounted on the left fastener stringer 6 is inserted through the margin of the slider 30. As shown in fig. 6, the thickness of the portion-to-be-pivoted 12 is set smaller than the interval between the upper shell plate 31a and the lower shell plate 31b in the slider 30, and the thickness of the fitting plate portion 11 is set smaller than the interval of the gap formed between the upper and lower flanges 32a, 32b of the slider 30. Therefore, the portion to be pivoted 12 of the mating body 10 can be easily inserted into the element guide passage of the slider 30.

The portion to be pivoted 12 inserted into the element guide passage 35 passes through a space between the upper and lower flanges 32a, 32b on the fitting body 10 side in the slider 30 and the slider holding portion 21 of the pivoting stopper body 20, and is inserted into and engaged with the pivoting stopper portion 23 of the pivoting stopper body 20 (see, for example, fig. 3). Since the intermediate portion 21a of the slider holding portion 21 is formed curvedly as described above in this first embodiment, the portion 12 to be pivoted can pass through the space between the upper and lower flanges 32a, 32b and the slider holding portion 21, thereby being stably inserted into the pivot stopper portion 23. Therefore, the left and right element rows 4 are positioned so as to allow stable coupling. Thereafter, the portion-to-be-pivoted 12 of the mating body 10 is engaged with the pivot stopper portion 23 of the pivot stopper body 20, and then, the slider 30 is slid upward so that the slide fastener 1 can be closed as in the first engaging operation.

In the first embodiment, in order to separate the slide fastener 1 from its closed state, the slider 30 is slid from its pulled state toward the pivoting stopper body 20 and brought into contact with the step portion 22. Subsequently, either of the two operations is performed to allow the left and right stringers 6, 6' to be separated. The two operations include: the portion-to-be-pivoted 12 of the fitting body 10 engaged with the pivot stopper portion 23 of the pivot stopper body 20 is pulled out from the side of the pivot stopper body 20 through a gap formed between the curved portion-side front end 23a of the pivot stopper body 20 and the slider 30; and pulling out the portion-to-be-pivoted 12 by passing the portion-to-be-pivoted 12 through the element guide passage 35 from the rear opening of the slider 30.

In particular, in the slide fastener 1 of the first embodiment, if the slider 30 is in contact with the step portion 22, the portion-to-be-pivoted 12 of the fitting body 10 can be pulled out from the side of the pivot stopper body 20 by inclining the left side fastener chain 6 with respect to the right side fastener chain 6'. When the portion-to-be-pivoted 12 is pulled out from the pivoting stopper body 20, the left and right fastener stringers 6, 6' can be easily separated from each other as compared with the case where the portion-to-be-pivoted 12 is pulled through the element guide passage 35 of the slider 30.

As described above, the slide fastener 1 with the separable rear stop as in the first embodiment has a structure capable of performing the first engaging operation of completing the engagement by fitting the mating body 10 from the side of the pivot stopper body 20 and the second engaging operation of completing the engagement by inserting the mating body 10 into the pivot stopper body 20 via the element guide passage 35 of the slider 30. Therefore, when closing the slide fastener 1, the user can arbitrarily select these two different joining operations. In addition, the first joining operation can close the slide fastener 1 of the first embodiment more easily than the second joining operation.

Therefore, if the user is not accustomed to the first coupling operation, he/she can smoothly close the slide fastener 1 without any trouble by performing the second coupling operation. In addition, when he/she is used to the first coupling operation, the operation of closing the slide fastener 1 can be easily performed by switching from the second coupling operation to the first coupling operation. That is, even a user who is merely accustomed to operating the ordinary separable bottom end stop with a plug pin or the like can easily operate the slide fastener 1 with the separable bottom end stop of the first embodiment, and in addition, when he/she is accustomed to the first coupling operation due to continuous use of the slide fastener 1, the closing or separation of the slide fastener 1 can be easily performed by the operation of switching the separable bottom end stop. Therefore, since the ease of use of the separable bottom end stop is improved and a person can satisfactorily operate the slide fastener, the slide fastener 1 of the first embodiment is excellent in practicality and operability.

(second embodiment)

Next, a slide fastener with a separable bottom end stop according to a second embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 7 is a perspective view of a main part of a separable back stop mounting portion of the slide fastener with the separable back stop of the second embodiment. Meanwhile, in the second embodiment and the third embodiment described later, the same reference numerals are used for components having the same configuration as the first embodiment, and therefore, explanation of these components is not repeated.

The slide fastener 41 with the separable bottom end stop of the second embodiment is provided with the separable bottom end stop 42 in which a mating body 43 and a pivoting stopper body 44 are formed continuously with the element rows 4 at the bottom ends of the right and left fastener tapes 2 so that they oppose each other. In the second embodiment, the tape end portion of the fastener tape 2 having the fitting body 43 is not cut off like the first embodiment, and the fitting body 43 is formed up to the tape end portion of the fastener tape 2.

The fitting body 43 is composed of a fitting plate portion 45 formed flat on the front and rear surfaces of the fastener tape 2, the portion to be pivoted 12 having the cylindrical pivot shaft 12a, the projecting portion 13, the coupling portion 14 and the recessed portion 15. The fitting plate portion 45 does not have the notch portion 16 provided in the first embodiment, and the pivot shaft 12a is formed at the rear end portion of the fitting plate portion 45. The thickness of the engaging plate portion 45 of the engaging body 43 is smaller than the interval of the gap formed between the upper and lower flanges 32a, 32b of the slider 30, and the thickness of the portion-to-be-pivoted 12 is smaller than the interval in the height direction of the element guide passage 35 in the slider 30.

The pivot stopper 44 is composed of the slider holding portion 21, a pivot stopper portion 46 formed thicker than the slider holding portion 21 by the step portion 22, the reinforcing portion 25, and the mating plate portion engaging groove 26. The pivot stopper portion 46 has a substantially J-shaped form as shown in a plan view thereof, and has a substantially J-shaped inner face 24 formed therein. A slit 47 is formed in this pivot stopper portion 46 so that it passes from the substantially J-shaped inner face 24 to the outer peripheral face of the pivot stopper portion 46, the slit 47 being formed from the bent portion front end 46a of the pivot stopper portion 46 along its bent shape and deeper than the slit 27 of the first embodiment.

The slide fastener 41 of the second embodiment having the separable back stop 42 has a structure capable of realizing a first engaging operation of fitting the portion-to-be-pivoted 12 of the fitting body 43 from the side of the pivot stopper body 44 and a second engaging operation of inserting the portion-to-be-pivoted 12 of the fitting body 43 into the pivot stopper body 44 through the element guide passage 35 of the slider 30 as in the first embodiment.

The first coupling operation is performed in the slide fastener 41 of the second embodiment as follows. The slider 30 is held on the slider holding portion 21 by the sliding operation, and then, the portion-to-be-pivoted 12 of the fitting body 43 is fitted into the pivoting space 28 from the side of the pivoting stopper body 44, i.e., through a gap formed between the bent portion-side front end 46a of the pivoting stopper portion 46 and the slider 30. With this operation, as shown in fig. 8, the portion-to-be-pivoted 12 is guided into and engaged with the pivot stopper portion 46 of the pivot stopper body 44.

Although there is no notched portion in the engaging plate portion 45 of the slide fastener 41 of the second embodiment as in the slide fastener 1 of the first embodiment, the engaging plate portion 45 and the fastener tape 2 do not interfere with the pivot stopper portion 46 because the slit 47 is formed long and narrow along a curved shape from the curved portion side front end 46a of the pivot stopper portion 46. Therefore, the pivot shaft 12a of the portion-to-be-pivoted 12 can be easily fitted into the curved surface of the substantially J-shaped inner face 24 of the pivot stopper portion 23.

Subsequently, the fitting body 43 is rotated about the pivot shaft 12a toward the pivot stopper 44 to insert the fitting plate portion 45 between the upper and lower flanges 32a, 32b of the slider 30. Thereafter, in a state where the engagement plate portion 45 is inserted into the element guide passage 35 through the gap between the upper and lower flanges 32a, 32b, the slider 30 is slid upward so as to close the slide fastener 41.

The second coupling operation is performed in the slide fastener 41 of the second embodiment as follows. The slider 30 is held on the slider holding portion 21 by sliding toward the pivoting stopper body 44, and then the pivot shaft 12a of the mating body 43 is inserted into the element guide passage 35 from the element opening of the slider 30 and is engaged with the pivoting stopper portion 46 of the pivoting stopper body 44. Thereafter, when the slider 30 is slid upward, the slide fastener 41 can be closed.

In the second embodiment, the first joining operation can also close the slide fastener 41 more easily than the second joining operation. When separating the slide fastener 41 from its closed state, two operations are performed to separate the left and right fastener stringers 6, 6', in which the portion-to-be-pivoted 12 is pulled from the side of the pivot stopper 44, and the pivot stopper 12 is pulled by passing the portion-to-be-pivoted 12 through the element guide passage 35 in the slider 30.

The slide fastener 41 with the separable back stop of the second embodiment allows two different first and second coupling operations to be selected when the user closes the slide fastener 41 as in the first embodiment. Therefore, the ease of use of the separable rear stop 42 is greatly improved, and excellent practicality and operability are ensured, which means that a person can operate the slide fastener satisfactorily.

(third embodiment)

Next, a slide fastener with a separable bottom end stop according to a third embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 9 is a perspective view of a main part of a separable back stop mounting portion of the slide fastener with the separable back stop of the third embodiment.

The slide fastener 51 with the separable bottom end stop of the third embodiment is provided with the separable bottom end stop 52 in which a mating body 53 and a pivoting stopper body 54 are formed continuously with the element rows 4 at the bottom ends of the right and left fastener tapes 2 so that they oppose each other.

In the third embodiment, the portion to be pivoted 55 of the fitting body 53 is composed of a cylindrical pivot shaft 12a provided to project from the fitting plate portion 11 in the fastener tape front and rear surface direction, and an outer peripheral portion 56 provided around the pivot shaft 12a in such a manner as to be flush with the front and rear surfaces of the fitting plate portion 11. A to-be-pivoted portion engaging groove 57 capable of rotatably engaging the outer peripheral portion 56 of the to-be-pivoted portion 55 and a fitting plate portion engaging groove 26 capable of engaging the fitting plate portion 11 of the fitting body 53 are continuously formed from the fitting plate portion engaging groove 26 in the substantially J-shaped inner face 24 of the pivot stopper portion 58 of the pivot stopper body 54. The construction of the third embodiment is substantially the same as that of the slide fastener 1 with the separable bottom end stop of the first embodiment.

The slide fastener 51 with the separable bottom end stop of the third embodiment can arbitrarily select two different first and second coupling operations when the user closes the slide fastener 51 as in the first embodiment. Therefore, the ease of use of the separable bottom end stop 52 is improved, and excellent practicality and operability are ensured, so that a person can satisfactorily operate the slide fastener. In addition, an outer peripheral portion 56 is formed on the portion-to-be-pivoted 55 of the fitting body 53, and a portion-to-be-pivoted engagement groove 57 capable of rotatably engaging the outer peripheral portion 56 is formed in the pivot stopper body 54. With this configuration, when the first and second engaging operations are performed, the fitting body 53 can be reliably engaged with the pivot stopper body 54, and in addition, the engaged state can be stably maintained.

(fourth embodiment)

A slide fastener with a separable bottom end stop according to a fourth embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 10 is a perspective view of a main part of a separable back stop mounting portion of the slide fastener with the separable back stop of the fourth embodiment.

The slide fastener 61 with the separable bottom end stop of the fourth embodiment is provided with the separable bottom end stop 62 in which a mating body 63 and a pivoting stopper body 64 are formed continuously with the element rows 4 at the bottom ends of the right and left fastener tapes 2 so that they oppose each other.

The fitting body 63 is composed of a fitting plate portion 65 formed flat on the front and rear surfaces of the fastener tape 2, a circular portion-to-be-pivoted 66 formed at the rear end portion of the fitting plate portion so as to be flush with the front and rear surfaces of the fitting plate portion 65, the protruding portion 13, the coupling portion 14, and the recessed portion 15. In the fourth embodiment, the thickness of the fitting plate portion 65 is smaller than the interval of the gap between the upper and lower flanges 32a, 32b of the slider 30. The portion to be pivoted 66 has the same thickness as the engaging plate portion 65, and the thickness of the portion to be pivoted 66 is smaller than the height of the element guide passage 35 in the slider 30 and smaller than the pitch of the gap formed between the upper and lower flanges 32a, 32 b.

In the fourth embodiment, a portion of the tape end side of the fastener tape 2 having the engaging body 63 is cut away like the first embodiment, and the engaging plate portion 65 extends rearward on the portion without the fastener tape. In addition, a notch portion 67 cut out from the belt end side toward the belt inner side is formed in the fitting plate portion 65, and it is deeper than the notch portion of the first embodiment.

The pivot stopper 64 is composed of the slider holding portion 21, the pivot stopper 68 formed thicker than the slider holding portion 21 by the step portion 22, the reinforcing portion 25, and the mating plate portion engaging groove 26. The pivot stopper portion 68 is formed in a generally J-shape like the first and second embodiments as seen in plan view thereof, and has a generally J-shaped inner face 24. On the other hand, the pivot stopper portion 68 has no slit in the first and second embodiments.

The slide fastener 61 of the fourth embodiment having the separable back stop 62 has a structure capable of realizing a first engaging operation of fitting the portion-to-be-pivoted 66 of the fitting body 63 from the side of the pivot stopper body 64 and a second engaging operation of inserting the portion-to-be-pivoted 66 of the fitting body 63 into the pivot stopper body 64 through the element guide passage 35 of the slider 30, as in the first and second embodiments.

The first coupling operation is performed in the slide fastener 61 of the fourth embodiment as follows. The slider 30 is held on the slider holding portion 21 by a sliding operation, and then, the portion-to-be-pivoted 66 of the fitting body 63 is fitted from the side of the pivot stopper body 64, introduced into the pivot space 28 in the pivot stopper portion 68, and engaged with the substantially J-shaped inner face 24. In the slide fastener 61 of the fourth embodiment, although there is no slit on the pivot stopper portion 68 as in the first and second embodiments, a deep notch portion 67 is formed in the fitting plate portion 65 of the fitting body 63. With this configuration, the fitting plate portion 65 does not interfere with the pivot stopper portion 68, so that the portion-to-be-pivoted 66 can be easily fitted into and engaged with the pivot stopper portion 68.

Subsequently, the fitting body 63 is rotated about the portion-to-be-pivoted 66 toward the pivoting stopper body 64, so that the fitting plate portion 65 is inserted into the element guide passage 35 through the upper and lower flanges 32a, 32b of the slider 30. Thereafter, in a state where the engaging plate portion 65 is inserted between the upper and lower flanges 32a, 32b, the slider 30 is slid upward so as to close the slide fastener 61 (see fig. 11).

The second coupling operation is performed in the slide fastener 61 of the fourth embodiment as follows. The slider 30 is held on the slider holding portion 21 by sliding, and then, the portion to be pivoted of the mating body 63 is inserted into the element guide passage 35 of the slider 30 and engaged with the pivot stopper portion 68 of the pivot stopper body 64. Thereafter, the slide fastener 61 can be closed by sliding the slider 30 upward.

In the fourth embodiment, when the first engaging operation is performed, the portion-to-be-pivoted 66 can be inserted into the element guide passage 35 not only from the leg opening of the slider 30 but also through a gap formed between the upper and lower flanges 32a, 32b arranged on the mating body 63 side of the slider 30 because the thickness of the portion-to-be-pivoted 66 of the mating body 63 is smaller than the pitch of the gap formed between the upper and lower flanges 32a, 32 b. Therefore, the operability of the second engaging operation can be improved.

As described above, when the slide fastener 61 is closed like the first embodiment, the slide fastener 61 with the separable bottom end stop of the fourth embodiment can select any one of two different coupling operations, i.e., the first and second coupling operations. Therefore, the ease of use of the separable rear stop 62 is greatly improved, and excellent practicality and operability are ensured, so that a person can satisfactorily operate the slide fastener.

(fifth embodiment)

A slide fastener with a separable bottom end stop according to a fifth embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 12 is a perspective view of a main part of a separable back stop mounting portion of the slide fastener with the separable back stop of the fifth embodiment.

The slide fastener 71 with the separable back stop of the fifth embodiment is provided with the separable back stop 72 in which a mating body 73 and a pivoting stopper 74 are formed continuously with the element rows 4 at the bottom ends of the right and left fastener tapes 2 so that they oppose each other.

The fitting body 73 of the fifth embodiment has the same configuration as the fitting body 63 of the fourth embodiment. On the other hand, the pivot stopper 74 has the slider holding portion 21, the pivot stopper portion 75 formed thicker than the slider holding portion 21 by the step portion 22, the reinforcing portion 25, and the mating plate portion engaging groove 26. The pivot stopper portion 75 is substantially rectangular in shape and is internally integrated with a slit 76 through which the fitting plate portion 65 and the portion-to-be-pivoted 66 can be inserted, a slit-shaped pivot space 28 into which the portion-to-be-pivoted of the fitting body 73 can be fitted, and a substantially J-shaped inner face 24 which is rotatably engaged with the portion-to-be-pivoted 66 fitted into the pivot space 28. Meanwhile, in the fifth embodiment, as shown in fig. 12, the slit 76 and the pivot space 28 are integrally constituted.

The slide fastener 71 with the separable bottom end stop of the fifth embodiment allows the user to select any one of two different coupling operations, i.e., the first and second coupling operations, when the slide fastener 71 is closed as in the first embodiment. Therefore, the usability of the separable rear stop 72 is greatly improved, and its practicality and operability are excellent, so that a person can satisfactorily operate the slide fastener. In addition, in the slide fastener 71 of the fifth embodiment, even if the slide fastener 71 receives an upward urging force at the time of closing thereof, the engaged state between the fitting body 73 and the pivot stopper body 74 can be stably maintained. This is because when the fitting body 73 is engaged with the pivot stopper 74, the portion-to-be-pivoted 66 can be engaged with the substantially J-shaped inner face 24 by being put into the pivot space 28 formed in the pivot stopper 75.
