Description

Slider

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a slide fastener for a slide fastener, and more particularly to a slider which can automatically tilt a pull tab when a slide operation of the slider is not performed, and keep the pull tab in a collapsed state.

Conventionally, the zipper is attached to the opening of an article such as a garment or a bag, and the slider attached to the zipper is slid along the element row, whereby the left and right element rows are engaged or separated to open and close the opening. The slider for zipper usually has a slider main body and a pull tab rotatably held relative to the slider main body, and between the lower flaps of the slider main body, a substantially Y-shaped guide for guiding the left and right chain rows is formed. Chain guide path.

Further, as one of the sliders, there is known a slider including a stopping mechanism for causing the stopping claw to protrude from the slider when the slider is stopped at any position on the element row of the zipper In the sprocket guiding path of the main body, the stopping claw portion is fitted between the fastener elements of the element row and is engaged with the element row, whereby the slider can be held at the stop position of the element row.

For example, Japanese Laid-Open Patent Publication No. 2009-61184 (Patent Document 1) discloses a slider having a stop mechanism integrally formed with two stop claw portions on a rotating shaft portion (a mounting shaft portion) of the pull tab.

In the slider of Patent Document 1, when the pull tab is lifted by a finger in order to operate the slider, the two stop claw portions formed on the rotary shaft portion of the pull tab are released from the fastener guide path of the slider main body. Therefore, the slider can be smoothly slid along the element rows.

On the other hand, when the finger is separated from the pull tab after the operation of the slider is completed, the pull tab is rotated by the self-weight to the side of the engagement opening of the slider body, whereby the claw of the pull tab is stopped. Abuts the chain of teeth. In this state, for example, since the left and right zipper tapes are forced to move the slider in the direction in which the sprocket rows are separated by the lateral pulling force, the two stopping claw portions provided on the pull tab are inserted into the zipper teeth of the respective sprocket rows. Therefore, each of the stopping claws is locked to the element row. Thereby, the forced movement of the slider can be stopped, thereby maintaining (locking) the stopped state of the slider.

Further, for example, Japanese Laid-Open Patent Publication No. 2007-111351 (Patent Document 2) discloses a slider with a stop mechanism attached between a flap and a flap on the slider body. The cover member is provided with a stop claw portion to hold the rotating shaft portion of the pull tab.

In the slider of Patent Document 2, an elastic piece portion that is elastically deformable is disposed on the cover member. Further, the cover member is slidably attached to the mounting post that is erected before the upper blade so as to sandwich the rotating shaft portion of the pull tab from the upper body of the slider body. In the slider of Patent Document 2 having such a cover member, when the pull tab is pulled by a finger for operating the slider, the cover member is lifted against the urging force of the elastic piece, and thus is disposed on the cover member. The stopping claw portion is disengaged from the sprocket guiding path of the slider main body. Thereby, the slider can be smoothly slid along the element row.

On the other hand, when the finger is separated from the pull tab after the operation of the slider is completed, the elastic piece portion of the cover member is elastically restored, the cover member is restored to (down to) the original position, and the stop claw portion disposed on the cover member is caused. It enters and exits in the sprocket guiding path of the slider body, and is locked between the zipper teeth of the sprocket row. Thereby, the stop state of the slider can be maintained (locked).

Moreover, in the slider, a slider having a function of automatically rotating the tab in a manner of lodging relative to the slider body after the operation of the slider is also known, while holding the tab Lodging state. Examples of such a slider are disclosed in Japanese Laid-Open Patent Publication No. Hei-3-295502 (Patent Document 3) or International Patent Publication No. 2012/042620 (Patent Document 4).

For example, the slider described in Patent Document 3 has a slider main body, a pull tab that is rotatably supported by the slider main body via a shaft portion, and a stop claw having a claw at one end portion. a first spring member that is integrally or separately provided from the stopping claw and urges the stopping claw; and a second spring member (hinge spring) that pushes the tab to a fallen state.

The slider main body of Patent Document 3 has a vertical wing plate and a guide post that connects the front ends of the upper and lower blades, and a substantially Y-shaped sprocket guide path is formed between the upper and lower blades. A pull-tab mounting portion for attaching a pull tab is formed on the upper blade, and a shaft portion that is inserted into the insertion hole of the pull-tab is attached to the pull-tab mounting portion. At one end of the pull tab, a cam portion that abuts against the stop claw is disposed.

The stop claw is swingably mounted to the slider body. Further, the stopping claw receives a pressing force from the first spring member, and the claw protrudes into the element guiding path of the slider body, and the pressing force is applied to the stopping claw, and the pulling piece is pulled via the cam portion. Push to the lodging state. On the other hand, when the pull tab is operated, the stop claw is lifted by the pressing force of the cam portion of the pull tab against the first spring member, whereby the claw portion can be released from the element guide path.

Further, in the slider of Patent Document 3, the second spring member which is a different member from the first spring member is disposed on the pull tab or the slider main body so as to press the pull tab in a collapsed state. In the slider of the patent document 3, for example, even when the claw portion of the pawl body and the fastener element are stopped from interfering with the fastener element when the sprocket row is stopped, the sprocket guide path cannot be sufficiently entered. 2 The spring member pushes the tab and remains in a falling state. Thereby, the pull tab can be prevented from swinging freely when the pull tab is not operated, so that the pull tab can be prevented from hooking other articles, and the appearance of the product can be prevented from being deteriorated due to the shake of the pull tab.

Further, Patent Document 4 describes a slider which is simplified in structure, smaller in size, and lighter in weight than the slider of Patent Document 3 described above. Here, the slider of Patent Document 4 will be specifically described with reference to FIGS. 17 and 18.

The slider 100 of Patent Document 4 has a slider main body 110, a pull tab 120 rotatably held by the slider main body 110, a spring member 130 including the stop claw portion 131, and a cover body 140 fixed to the slider main body 110.

The slider body 110 has upper and lower flaps 111 and 112 and a guide post 113 that connects the front ends of the upper and lower flaps 111 and 112. The front end portion and the rear end portion of the upper surface of the upper wing plate 111 are provided with a mounting post 111a and a rear mounting post 111b for mounting the outer cover body 140. An insertion portion 111c into which the attachment shaft portion 121 disposed at one end of the tab 120 is inserted is provided between the front mounting post 111a and the rear mounting post 111b. By inserting the mounting shaft portion 121 of the pull tab 120 into the insertion portion 111c, the outer cover 140 is fixed to the front mounting post 111a and the rear mounting post 111b, and the mounting shaft portion 121 of the tab 120 is held on the upper wing. Between the plate 111 and the outer cover 140.

Further, between the front mounting post 111a and the rear mounting post 111b in the upper blade 111, a pair of vertical wall portions 111d are disposed. A claw hole 111f through which the stop claw portion 131 of the spring member 130 is inserted is formed in a portion surrounded by the rear mounting post 111b and the pair of vertical wall portions 111d.

The pull tab 120 has a flat-shaped grip portion 122, a pair of right and left leg portions 123 extending from the grip portion 122, and a mounting shaft portion 121 that is transversely disposed between the front ends of the pair of leg portions 123, and is grasped by The holder portion 122, the pair of leg portions 123, and the attachment shaft portion 121 are surrounded to form a tab-shaped opening portion 124 having a substantially rectangular shape.

A cam portion 125 having a shape that protrudes toward the tab opening portion 124 is disposed at a substantially central portion of the mounting shaft portion 121 in the width direction of the slider. Further, a left-right abutting portion 126 that is extended toward the tab opening portion 124 and abuts against the outer cover body 140 is disposed at a portion where the leg portion 123 and the attachment shaft portion 121 are coupled.

The spring member 130 has a main body portion 132 that spans the cam portion 125 of the pull tab 120, a stop claw portion 131 that is suspended from the rear end of the main body portion 132, and a curved portion that extends from the rear side of the main body portion 132 to extend upward. Elastic piece portion 133.

The outer cover body 140 has a substantially rectangular top wall portion 141, left and right side wall portions 142 that are suspended from the side edge portions of the top wall portion 141, and a front wall portion 143 and a rear wall that are suspended from the front end portion of the top wall portion 141. Part 144. A receiving groove portion 145 that accommodates the elastic piece portion 133 of the spring member 130 is formed on the back surface (inner surface) of the top wall portion 141.

The left and right side wall portions 142 of the outer cover body 140 are formed with a cover opening portion 146 that opens from the lower end edge toward the top wall portion 141, and the mounting shaft portion 121 that accommodates the pull tab 120 in the cover opening portion 146. In this case, the front surface portion of the left and right side wall portions 142 facing the outer cover opening portion 146 on the front side is configured such that the abutting portion 126 of the tab 120 abuts to restrict the restriction of the rotation range of the tab 120. Department 147.

In the case of assembling the slider 100 of the patent document 4 having the member as described above, on the upper surface of the flap 111 above the slider body 110, the mounting shaft portion 121 of the tab 120 is inserted into the front and rear mounting posts 111a, The pull tab 120 is placed in a manner between 111b. Further, the spring member 130 is disposed on the wing plate 111 on which the pull tab 120 is placed. At this time, the spring member 130 is disposed such that the body portion 132 straddles the cam portion 125 of the pull tab 120 and contacts the cam portion 125.

Next, the outer cover body 140 is attached to the slider body 110. At this time, after the outer cover 140 is covered at a specific position of the upper blade 111, one of the left and right side wall portions 142 of the outer cover 140 is pressed toward the inner side to be plastically deformed, thereby fixing the outer cover 140 to the slider main body. The posts 111a, 111b are mounted before and after 110. As described above, by fixing the outer cover 140 to the slider main body 110, the pull tab 120 is mounted so as to be centered on the mounting shaft portion 121, and is in a state of falling toward the engagement opening side of the slider main body 110 to abut against the outer cover body 140. The restricting portion 147 is rotatable in a range in which the state is raised.

According to the slider 100 of Patent Document 4, the slider structure can be simplified as compared with, for example, the slider of Patent Document 3, and the assembly work of the slider 100 can be performed relatively easily. Further, the pressing force of the spring member 130 can be applied to the cam portion 125 of the pull tab 120, whereby the stopping claw portion 131 of the spring member 130 is caused, for example, in a state where the pull tab 120 is laid down toward the engaging opening side of the slider main body 110. When the sprocket guiding path is engaged and engaged with the element row, the slider 100 can be held in a state of being stopped relative to the element row.

Further, when the pull tab 120 is operated to rise from the lodging state, the cam portion 125 of the pull tab 120 lifts the spring member 130 upward against the urging force of the elastic piece portion 133 of the spring member 130, and thus the spring member 130 The stop claw portion 131 is withdrawn from the element guide path. therefore, The slider 100 can be smoothly slid along the element rows.

Further, in the slider 100 of Patent Document 4, since the cam portion 125 of the pull tab 120 can be pressed by the spring member 130, the pull tab 120 can be rotated so as to fall toward the engagement opening side. Therefore, for example, when the grip portion 122 of the pull tab 120 is released after the operation of the slider 100 is completed, the pull tab 120 can be automatically rotated toward the meshing opening side by the urging force of the spring member 130, thereby being depressed. The stop claw portion 131 of the spring member 130 can be brought into the sprocket guide path to automatically actuate the stop mechanism.

In the slider described in Patent Document 1 or Patent Document 2, when the slider is not in operation, the slider is freely swung and shaken with respect to the slider body, thereby causing deterioration in appearance or obstruction of the tab. Case. Moreover, if the pull tab is shaken, there is a case where the pull tab is hooked on other articles, and it is considered that there is also damage to the article to which the zipper is attached or the other article to which the pull tab is hooked.

On the other hand, in the slider described in Patent Document 3, since the pull tab is released after the operation of the slider is completed, the pull tab can be laid down by the pressing force of the first spring member and the second spring member, thereby further Keep the pull-down state of the pull tab. Therefore, it is possible to prevent the slider from being shaken like the slider of Patent Document 1 or Patent Document 2.

However, in the slider of Patent Document 3, two elastic members of the first spring member and the second spring member are required. Therefore, the number of parts of the slider increases, resulting in the cost of the slider Increase.

Further, in the case of the slider of the patent document 3, for example, when the coil-shaped elastic member is used for the first spring member and the second spring member, even if the tab is gripped by the finger, the engagement with the slider body is performed. The upper surface of the mouth side is rotated more than 90°, but as long as the pull tab is released, the pressing force of the first spring member and the second spring member also acts on the pull tab to allow the pull tab to be engaged with the slider body. Side down. However, when the coil-shaped elastic member is used as the first spring member and the second spring member, the cost of the slider is further increased, and the assembly work of the slider is complicated.

On the other hand, Patent Document 3 discloses that the first spring member and the second spring member do not use a coil-shaped elastic member, and an elastic member that bends a leaf spring-shaped elastic member or a leaf spring into a specific shape is used. (hereinafter, the slider in which the elastic members are simply referred to as leaf spring-like elastic members) is one of the embodiments.

By using such a leaf spring-shaped elastic member as the first spring member and the second spring member, the assembly work of the slider can be simplified as compared with the case of using the coil-shaped elastic member. However, in the slider using the leaf spring-like elastic member, the pull tab can be biased in a specific direction by the pressing force of the first spring member and the second spring member (for example, toward the meshing port side of the slider main body) The direction of the lodging is that the angle of inclination of the fallen tab is limited to the narrow range.

Therefore, for example, if the tab is inclined to an angle exceeding the range, the tilt state of the tab is held by the pressing force of the first spring member or the second spring member, or the tab is oriented in a direction opposite to the specific direction. (For example, in the direction in which the side of the slider main body is undulated), the pull-up is caused by the tabs causing the person to be disturbed or hooking other articles.

In the slider 100 described in Patent Document 4, the range in which the slider 120 is rotatable is limited in advance by the restricting portion 147 of the outer cover 140, and the pull tab 120 is pulled in the angular range. The cam portion 125 of the 120 is pressed by the spring member 130 to cause the pull tab 120 is tilted in a specific direction (the direction in which the side of the main body of the slider is laid down).

The slider 100 of the patent document 4 does not use a coil-shaped elastic member, and the assembly work of the slider 100 is also relatively simple, so that the slider 100 can be provided at a relatively low cost.

However, in the slider 100 of Patent Document 4, since the outer cover body 140 is provided with the restricting portion 147, the range in which the pull tab 120 can be rotated is relatively small, so that it is difficult to perform the sliding operation of the slider 100. Therefore, it is desirable to increase the range of the inclination angle at which the pull tab 120 can be lowered, and to improve the operability of the slider 100.

Further, in the slider 100 of Patent Document 4, if the inclination angle of the tab 120 with respect to the upper surface of the engagement opening side of the upper blade 111 becomes larger, the cam portion 125 of the tab 120 is pushed from the spring member 130. The tendency of the pressure to weaken. Therefore, it is desirable that even if the inclination angle of the pull tab 120 becomes large, the urging force of the spring member 130 is appropriately applied to the cam portion 125 of the pull tab 120, so that the pull tab 120 is stably undulated.

The present invention has been made in view of the above-mentioned problems, and a specific object thereof is to provide a slider which can automatically tilt a tab when the sliding operation of the slider is not performed, and maintain the pull-down state of the tab, and The rotation range of the pull tab can be set to be large.

In order to achieve the above object, the most important feature of the slider provided by the present invention is that it is a slider for a zipper, and as a basic structure, has a slider main body, and an inlet-side end portion of the upper and lower flaps is guided by a tab pressing member; the tab pressing member is provided with at least a portion of the elastic deformation portion and rotatably attached to the slider body; and the tab is disposed on the upper surface of the upper flap and the tab The mounting shaft portion between the pressing members is rotatably held; and the mounting shaft portion of the pull tab has a cam portion that abuts against the pull tab pressing member, and the pull tab pressing member is formed by the pull tab The elastically deformable portion is elastically deformed by the operation, and the elastic piece is restored by the elastic deformation portion to cause the pull-tab to be laid down via the cam portion; and the cam portion has a first cam portion that is mounted from the pull-tab a shaft portion protruding; and a second cam portion that is mounted from the pull tab The shaft portion protrudes in a direction different from the first cam portion.

In the slider according to the present invention, preferably, the first cam portion abuts against the tab pressing member when the tab rotates within a first rotation range before a specific cam switching angle, and the second cam portion The cam portion abuts at least the pull-tab pressing member when the pull-tab is rotated in the second rotation range equal to or higher than the cam switching angle, and the first cam portion has the above-mentioned contact in the first rotation range The pull-tab pressing member receives a pressing force to urge the pull-tab to rotate in a falling direction, and the second cam portion has a pressing force from the pull-tab pressing member that abuts from the second rotation range to urge the The form in which the pull piece rotates in the direction of the lodging.

Moreover, it is preferable that the slider of the present invention has a rotation restricting portion that restricts a rotation range of the pull tab and defines an upper limit of the second rotation range. In this case, it is preferable that the rotation restricting portion is configured by a rocking restricting portion that is disposed on the slider main body and that abuts the tab pressing member to restrict a swing range of the tab pressing member.

Further, in the present invention, the slider may have a cover member that is attached to the slider pressing member and that is fixed to the slider body, and the rotation restricting portion may be biased by the cover member A stop portion that stops the rotation of the pull tab is formed.

Further, in the slider according to the present invention, preferably, the tab pressing member is configured by a single member, and has a first abutting portion that abuts the first cam portion, and the first portion 2 The second abutting portion where the cam portion abuts.

In this case, it is particularly preferable that the first cam portion and the second cam portion are disposed at different positions along a direction of an axis of the mounting shaft portion, and the first abutting portion and the second abutting portion are provided at The pull tab pushes the different positions of the member.

Moreover, it is preferable that the protruding direction of the second cam portion from the mounting shaft portion is inclined toward the lodging direction side of the pull-tab from the direction in which the first cam portion protrudes from the mounting shaft portion.

Further, in the slider of the present invention, preferably, the first cam portion has the following shape When the slider is viewed from the side surface side in the first rotation range, the contact point of the first cam portion with respect to the tab pressing member is disposed in contact with the mounting shaft portion of the pull tab The contact of the upper surface of the wing plate is further the side of the grip portion of the above-mentioned pull tab in the lodging state.

Furthermore, it is preferable that the second cam portion has a configuration in which the second cam portion is disposed at a contact point of the tab pressing member when the slider is viewed from a side surface side in the second rotation range. The contact point of the upper surface of the upper wing plate is contacted with the contact shaft portion of the pull tab, and the grip portion side of the pull tab is further lowered.

Further, in the slider of the present invention, preferably, the upper blade is provided with a claw hole, and the second cam portion is configured as a stopping claw portion, and the stopping claw portion is configured to pass through the claw hole The substantially Y-shaped sprocket guide path disposed between the upper and lower flaps of the slider main body advances and retracts.

On the other hand, in the slider of the present invention, the upper wing plate may be provided with a claw hole, and the pull piece pressing member may have a stopping claw portion, and the stopping claw portion may be disposed through the claw hole. The substantially Y-shaped sprocket guide path between the upper and lower blades of the slider main body advances and retracts.

The slider of the present invention has at least: a slider body; a tab pressing member having at least a portion having an elastic deformation portion; and a tab held to be pushable via the flap and the tab disposed on the slider body The pressing member rotates with the mounting shaft portion; and the pull tab includes the first cam portion that protrudes from the mounting shaft portion and the second cam portion that protrudes from the mounting shaft portion in a direction different from the first cam portion. unit.

According to the slider of the present invention configured in this manner, the first cam portion and the second cam portion provided on the mounting shaft portion of the pull tab can be protruded from each other in different directions, and the inclination angles of the tabs are different from each other. Within the range, the pull tab is caused to rotate in the lodging direction, so that the pull tab is stably collapsed.

Therefore, in the slider of the present invention, by appropriately setting the protruding direction of the first and second cam portions or the shape of the cam surface, for example, even on the upper surface of the engaging opening side of the tab relative to the upper blade When the inclination angle is greater than 90° and further 120° or more, the first cam portion of the pull tab may be brought into contact with the pull tab pressing member or the second cam portion of the pull tab may be used. The cam portion selectively abuts continuously against the tab pressing member to cause the tab to fall toward the engagement opening side of the slider body.

In other words, the slider of the present invention can set the tilt angle range of the slider which can cause the tab to fall toward the engagement opening side of the slider body, as compared with the previous slider described in, for example, Patent Document 3 or Patent Document 4. It is larger, thereby improving the operability of the slider.

Further, in the slider of the present invention, the first cam portion and the second cam portion of the pull tab can be selectively brought into contact with the tab pressing member in accordance with the tilt angle of the pull tab, thereby being appropriately pulled. The pressing force generated by the elastic deformation portion of the sheet pressing member can effectively exert the pressing force of the tab pressing member on the tab regardless of the inclination angle of the tab, so that the tab can be stably poured.

In particular, in the present invention, the first cam portion of the pull tab abuts on the first rotation range in which the pull tab is in a state where the pull tab is at an inclination angle at which the pull tab is at a specific cam switching angle with respect to the upper flap surface. The pull-tab pressing member is configured to be configured such that the second cam portion of the pull-tab is configured to at least abut against the pull-tab pressing member in the second rotation range in which the tilt angle of the pull-tab is equal to or greater than the cam switching angle.

In other words, the first cam portion is disposed so as to be able to abut against the tab pressing member in a first rotation range in which the inclination angle of the tab is an angle of 0° at which the tab is completely collapsed to a specific cam switching angle or lower. Further, the second cam portion is disposed so as to be at least in contact with the tab pressing member in a second rotation range in which the inclination angle of the tab is from the cam switching angle or more to the rotation upper limit. Further, the second cam portion may be disposed so as to be in contact with the tab pressing member from a range in which the inclination angle of the tab is smaller than the cam switching angle. Furthermore, in the present invention, the cam switching angle can be set to an arbitrary size.

Further, the first cam portion and the second cam portion have a configuration in which the tab pressing members abutted from the first cam portion and the second cam portion are pushed in the first rotation range and the second rotation range, respectively. The pressure causes the pull tab to rotate in the direction of the fall.

By configuring the first cam portion and the second cam portion of the pull tab in this manner, the first cam portion and the second cam portion can be selectively brought into contact with the tab pressing member, thereby enabling a more stable urging. The pull tab rotates in the lodging direction, and the range of the tilt angle of the pull tab that can cause the pull tab to fall can be expanded to two ranges of the first rotation range and the second rotation range.

Further, the slider of the present invention has a rotation restricting portion that limits the rotation range of the pull tab and defines an upper limit of the second rotation range. Thereby, the first cam portion or the second cam portion of the pull tab can be stably abutted against the tab pressing member in the rotation range of the tab which is restricted by the rotation restricting portion, so that the tab can be pressed The pushing force of the member smoothly acts on the pull tab to cause the pull tab to fall.

In this case, the rotation restricting portion is configured by a rocking restricting portion that is disposed on the slider main body and that abuts the tab pressing member to restrict the swing range of the tab pressing member. By providing such a rocking restricting portion to restrict the swinging range of the tab pressing member, the rotation restricting portion can be easily configured, and the upper limit of the rotation of the tab can be stably set.

Moreover, the slider of the present invention may have a cover tab pressing member and be fixed to the slider body outer cover member, and the rotation restricting portion stops the rotation of the tab by the collision of the tab member by the cover member. Department composition. By the tab contact portion of the cover member, the rotation restricting portion can be simply configured, and the upper limit of the rotation of the pull tab can be stably set.

Further, in the slider of the present invention, the tab pressing member is constituted by a single member, and has a first abutting portion that abuts the first cam portion and abuts the second cam portion. The second abutment. Thereby, the slider can be formed with a small number of parts, so that the manufacturing cost of the slider can be reduced, and the assembly work of the slider can be simplified.

In this case, the first cam portion and the second cam portion of the pull tab are disposed at different positions along the direction of the axis of the mounting shaft portion, and the first abutting portion and the second abutting portion are respectively provided Different positions of the tab pressing members corresponding to the positions of the first cam portion and the second cam portion. Thereby, the first cam portion and the second cam portion can be selectively and stably and smoothly abutted against the tab pressing member according to the inclination angle of the tab, so that the tab can be more stably urged toward the tab member. Rotate in the direction of lodging.

Further, in the slider of the present invention, the protruding direction of the second cam portion from the mounting shaft portion is inclined toward the lodging direction side of the pull tab from the protruding direction of the first cam portion from the mounting shaft portion. Thereby, even if the pull piece is rotated to be larger than the second rotation range of the first rotation range in which the first cam portion is in contact with the pull-tab pressing member, the second cam portion can be brought into contact with the pull-tab. The pressing member urges the pressing force of the pull-tab pressing member to effectively act on the pull-tab, thereby causing the pull-tab to rotate in the lodging direction, thereby causing the pull-tab to stably fall down.

Further, in the slider according to the present invention, the first cam portion has a configuration in which the first cam portion is viewed from the side surface side in a first rotation range in which the inclination angle of the pull tab is equal to or less than the cam switching angle. The abutting point with respect to the pull-tab pressing member is disposed on the side of the grip portion (hand-held portion) of the pull-tab in the lodging state of the contact point of the mounting shaft portion of the pull-tab contacting the upper surface of the upper flap. When the first cam portion is brought into contact with the tab pressing member and the pressing force of the tab pressing member acts on the first cam portion, the tab can be stably urged toward the engaging opening side of the slider body. Rotate in the direction of lodging.

Further, the first cam portion 26 is provided inside the left and right side frame portions 23, but in the present invention, any one of the left and right first cam portions 26 may be excluded, and the shaft portion of the pull tab 20 may be attached. Only one first cam portion 26 is provided.

The first cam portions 26 on the left and right in the first embodiment have the same shape, and protrude from the attachment shaft portion 21 toward the inside of the opening window portion 24. Further, each of the first cam portions 26 has a configuration in which the pull tab 20 is in a fallen state (the inclination angle of the pull tab 20 with respect to the upper surface of the engaging opening side of the upper flap 11 is 0°) to the pull tab 20 When the tilt angle is rotated within the first rotation range in a state where the tilt angle is a specific cam switching angle (for example, 100°), the outer cover member 30 can be lifted by abutting against the left and right side wall portions 32 of the cover member 30. Further, in the present invention, the cam switching angle can be set to an arbitrary size by changing the shape or size of the first cam portion 26 and the second cam portion 27.

In this case, the abutting surface of the first cam portion 26 that abuts against the left and right side wall portions 32 of the cover member 30 becomes a cam surface. Further, the shape of the first cam portion 26 (in particular, the cam surface shape of the first cam portion 26) is formed such that the left and right side wall portions 32 of the cover member 30 abut against the first cam portion 26, When the abutting outer cover member 30 is pressed by the elastic deformation portion 36 described below, the pull tab 20 is caused to rotate in a direction in which the pull tab 20 is tilted toward the engagement opening side of the slider main body 10 (see, for example, FIG. 10).

Specifically, the first cam portion 26 has a configuration in which the first cam portion 26 is opposed to the cover member 30 when the slider 1 is viewed from the side surface side when the tilt angle of the tab 20 is equal to or less than the cam switching angle. The abutting point P1 is disposed on the slider 20 in the longitudinal direction of the slider. The contact P2 of the mounting shaft portion 21 contacting the upper surface of the upper blade 11 is closer to the grip portion 22 side (i.e., the rear side) of the pull tab 20 in the lodging state.

On the other hand, the second cam portion 27 in the first embodiment is provided to protrude from the mounting shaft portion 21 toward the back side of the pull tab 20. In this case, the protruding direction of the second cam portion 27 from the mounting shaft portion 21 to the left and right first cam portions 26 from the protruding direction of the mounting shaft portion 21 is to the tab 20 which is the side of the pull tab 20 in the lodging direction. The back side is inclined by about 90°.

Further, in the present invention, the direction of the lodging is the rotation direction in which the attachment shaft portion 21 of the pull tab 20 is rotated, and the handle 20 is pressed by the cover member 30 which is the handle of the tab pressing member. The direction of rotation in which the lodging is reversed, for example, in the cross-sectional views shown in FIGS. 8 to 11, refers to the counterclockwise direction in which the tab 20 is rotated toward the engagement opening side of the slider body 10 around the attachment shaft portion 21.

Further, the second cam portion 27 has a configuration in which the upper limit of the rotation of the pull tab 20 to the specific cam switching angle of the pull tab 20 to the upper limit of the rotation of the pull tab 20 is the rocking restriction of the cover member 30 contacting the slider main body 10. When rotating in the second rotation range of the state of the portion 16b, the outer cover member 30 can be lifted by abutting against the inner wall surface of the upper wall portion 31 of the outer cover member 30.

In this case, the abutting surface of the second cam portion 27 that abuts against the inner surface of the upper wall portion 31 of the cover member 30 becomes a cam surface. Further, the shape of the second cam portion 27 (particularly, the cam surface shape of the second cam portion 27) is formed such that when the upper wall portion 31 of the cover member 30 abuts against the second cam portion 27, When the abutting outer cover member 30 is pressed by the elastic deformation portion 36, the pull tab 20 is caused to rotate in a direction in which the pull tab 20 is laid down toward the engagement opening side of the slider main body 10 (see, for example, FIG. 11).

Specifically, the second cam portion 27 has a configuration in which the second cam portion 27 is opposed to the cover member 30 when the slider 1 is viewed from the side surface side when the tilt angle of the tab 20 is equal to or greater than the cam switching angle. The abutment point P3 is disposed on the side of the grip portion 22 of the pull tab 20 in the lodging state of the contact shaft portion 21 of the pull tab 20 contacting the upper surface of the upper flap 11 in the longitudinal direction of the slider (ie the rear side).

Further, the second cam portion 27 of the first embodiment can be configured to be slidable through the penetration portion of the claw hole 11c of the upper blade 11 so as to function as a stop claw portion constituting the stop mechanism of the slider 1.

Further, the insertion recessed portion 32a is opened in the slider width direction, and the size (area) of the opening portion of the insertion recessed portion 32a is set in consideration of the shape and size of the first cam portion 26 of the tab 20.

In this case, the end surface of the side wall portion 32 that is disposed on the opening side corresponding to the position of the first cam portion 26 so as to face the insertion recess portion 32a serves as the first contact portion of the first cam portion 26 of the tab 20 1 is formed by the abutting portion. In the first embodiment, the first abutting portion formed by inserting the end surface on the opening side of the recessed portion 32a and the second abutting portion formed by the inner wall surface of the upper wall portion 31 are formed in each other. Not the same location.

The left and right arm portions 33 of the cover member 30 are protruded forward from the lower end portions of the left and right side wall portions 32. The interval between the inner wall surfaces of the left and right arm portions 33 is set to be larger than the width dimension between the left and right outer side surfaces of the upper end portion of the locking head portion 15a of the front mounting post 15 and the width dimension between the left and right side surfaces of the fitting portion 15b. And it is set to be smaller than the width dimension between the left and right outer side faces in the lower end portion of the locking head portion 15a.

Further, the left and right arm portions 33 have a size that can be fitted into the fitting portion 15b of the front mounting post 15 when the cover member 15 is attached to the slider body 10 before the cover member 30 is attached. Further, as shown in FIG. 8, the upper surface portion of the right and left arm portions 33 is formed to be inclined upward from the base end portion of the arm portion 33 toward the distal end portion so as to gradually increase in height.

In this manner, by raising the upper surface portion of the arm portion 33 toward the front, it is possible to be on the base end side of the arm portion 33, below the engaging surface of the upper surface of the arm portion 33 and the front mounting post 15. A space margin is set between the surfaces. With this, the left and right arm portions 33 of the cover member 30 can be easily oscillated so that the rear end portion of the cover member 30 can be moved in the vertical direction in a state where the insertion portion 15b of the front mounting post 15 is fitted.

The left and right locking portions 34 of the cover member 30 are bent downward with respect to the arm portion 33, and are configured such that when the left and right arm portions 33 of the cover member 30 are fitted into the fitting portion 15b of the front mounting post 15, they can be locked. The locked portion 11b at the front end of the upper blade 11 is.

The left and right leg portions 35 of the cover member 30 are provided to protrude rearward from the left and right side wall portions 32, and the abutting piece portions 35a are disposed at the rear end portions of the left and right leg portions 35, and the abutting piece portions 35a are pulled by When the sheet member 20 is lifted up to the rocking limit position by the operation of the sheet 20, it abuts against the rocking restricting portion 16b of the rear mounting post 16. In this case, the interval between the inner wall surfaces of the left and right leg portions 35 is set to be larger than the width dimension of the base portion 16a of the rear mounting post 16, and is set smaller than the width dimension of the rocking restricting portion 16b of the rear mounting post 16.

The elastic deformation portion 36 of the cover member 30 has a shape that is extended forward from the front end of the upper wall portion 31 and curved downward, and is configured to be elastically deformable so that the curvature of the curved portion changes. Further, the elastic deformation portion 36 has a width dimension smaller than the groove width of the accommodation groove portion 15d provided in the front mounting post 15. Further, on the outer surface of the elastic deformation portion 36, a groove portion 36a is recessed in order to facilitate elastic deformation of the elastic deformation portion 36.

The elastic deformation portion 36 configured in this manner can stably obtain a large elastic force, so that the outer cover member 30 pushes the first cam portion 26 of the pull tab 20 or the second portion by the elastic recovery of the elastic deformation portion 36. In the case of the cam portion 27, a large pressing force can be applied to the first cam portion 26 or the second cam portion 27.

Next, a procedure for assembling the slider 1 of the first embodiment having the above-described constituent parts will be described.

First, the mounting shaft portion 21 of the pull tab 20 is inserted between the reinforcing portion 11a and the vertical wall portion 11d of the upper blade 11 of the slider body 10, and the slider 20 is turned upside down (sliding) the slider body In the state of the engagement opening 10 of the 10, the pull tab 20 is placed on the slider main body 10.

Then, the cover member 30 is attached to the slider main body 10 on which the pull tab 20 is placed. Specifically, the left and right leg portions 35 of the cover member 30 are inserted into the side of the base portion 16 a of the rear mounting post 16 and attached to the rear mounting post 16 .

Then, after the left and right leg portions 35 of the cover member 30 are inserted into the rear mounting post 16 and attached to a specific position, the elastic deformation portion 36 of the cover member 30 is inserted into the housing groove portion 15d of the front mounting post 15, and the cover member 30 is attached. The left and right arm portions 33 are placed on the locking head portion 15a of the front mounting post 15.

Thereafter, the cover member 30 is pressed into the front mounting post 15 from the upper side, and the elastic deformation portion 36 of the cover member 30 is further inserted into one side with the groove bottom portion of the receiving groove portion 15d, and the cover member is further inserted therein. The left and right arm portions 33 of 30 are lowered to the position of the fitting portion 15b of the front mounting post 15 while being in contact with the outer side surface of the locking head portion 15a.

At this time, the left and right arm portions 33 and the side wall portions 32 of the outer cover member 30 are elastically deformed while being gradually expanded toward the outer side in the width direction by the downward inclination of the locking head portion 15a. Further, by bringing the front end edge of the left and right arm portions 33 of the cover member 30 into contact with the front bulging portion 15c of the front mounting post 15, the cover member 30 is lowered while being guided to a specific position by the front bulging portion 15c. The left and right arm portions 33 of the cover member 30 can be smoothly moved to the position of the fitting portion 15b of the front mounting post 15.

Then, by moving the right and left arm portions 33 of the cover member 30 beyond the locking head portion 15a of the front mounting post 15 to the position of the fitting portion 15b, the arm portion 33 and the side wall portion 32 of the cover member 30 can be elastically restored. The fitting portion 15b of the front mounting post 15 is fitted, and the right and left locking portions 34 of the cover member 30 are locked to the locked portion 11b provided at the front end portion of the upper blade 11. At the same time, the mounting shaft portion 21 of the pull tab 20 is inserted into the insertion recess 32a of the cover member 30, and the mounting shaft portion 21 is rotatably held by the upper surface of the upper blade 11 and the left and right side walls of the cover member 30. Between 32.

The slider 1 of the first embodiment shown in Fig. 1 can be assembled by performing the above assembly work.

The slider 1 of the first embodiment obtained in this manner can constitute a slide fastener by inserting the element rows of the left and right fastener stringers into the element guide path of the slider 1. Further, in the case of constituting the zipper, the slider 1 of the first embodiment is fastened to the pull tab by, for example, as shown in FIGS. 3 and 4, by pulling the tab 20 toward the engagement opening side of the slider body 10. The detachment portion 17 allows the second cam portion 27 functioning as the stop claw portion to enter the sprocket guide path of the slider body 10, thereby actuating the stop mechanism.

On the other hand, the slider 1 is rotated by the grip portion 22 of the pull tab 20 with the finger, and the pull tab 20 is pivoted about the mounting shaft portion 21 of the pull tab 20, For example, as shown in Fig. 9, the first cam portion 26 and the second cam portion 27 of the pull tab 20 are also rotated to change their orientation.

At this time, the first cam portion 26 that is rotated can gradually lift the cover member 30 against the urging force of the elastic deformation portion 36 of the cover member 30, and the second cam portion 27 can be withdrawn from the chain of the slider body 10. Tooth guiding road. Thereby, the slider 1 can be smoothly slid along the element rows.

Further, for example, as shown in FIG. 9, when the pull tab 20 is rotated so as to be inclined by approximately 60 degrees with respect to the upper surface of the engagement opening side of the upper blade 11, the first cam portion 26 is opposed to the cover member 30. The abutting point P1 is disposed in the longitudinal direction of the slider, and is disposed at a position closer to the contact point P2 of the upper surface of the upper blade 11 than the mounting shaft portion 21 of the pull tab 20, and the grip portion 22 of the pull tab 20 in the lodging state Side (rear side).

Therefore, the pull tab 20 is freed by releasing the grip portion 22 of the pull tab 20, and the pressing force generated by the elastic deformation portion 36 of the cover member 30 acts on the first cam portion 26, and the first cam portion is applied to the first cam portion. The force of the downward direction or the obliquely downward direction is applied to the abutment point P1 of the cover member 30, so that the pull tab 20 can be urged to rotate toward the engagement port side of the slider main body 10, so that the pull tab 20 can be stably laid down.

Further, in the slider 1 of the first embodiment, the pull-tab releasing portion 17 is vertically provided on the upper blade 11, so that the pull-tab 20 is pulled in the direction of the lodging even by the pressing force of the elastic deformation portion 36 of the cover member 30. Rotating, the pull tab 20 can also be abutted against the pull-tab release portion 17 to prevent lodging to the pull tab 20 The inclination angle becomes 0°.

In the first embodiment, when the pull tab 20 is laid down in such a manner as to abut against the pull-tab releasing portion 17, the pressing force of the elastic deformation portion 36 acts on the first cam portion 26, and becomes a pull. The second cam portion 27 of the sheet 20 is in contact with the element row of the fastener stringer.

Therefore, for example, the second cam portion 27 can be inserted into the element guide path of the slider body 10 by pressing the tab 20 toward the tab releasing portion 17 to be engaged with the tab releasing portion 17, thereby embedding the chain. The zipper teeth of the tooth row can be actuated by the stop mechanism. By actuating the stop mechanism in this manner, the slider 1 is locked with respect to the element rows, and a higher locking strength (stop holding force) can be obtained.

Further, in a state where the pull tab 20 is lowered to abut against the tab release portion 17, and the second cam portion 27 is brought into contact with the element row, for example, the slider is forcibly caused by the lateral tension of the left and right fastener links 1 moves in the direction in which the element rows are separated, whereby the second cam portion 27 of the tab 20 also moves in accordance with the relative movement of the element rows with respect to the slider 1, so that the tab 20 is further rotated in the direction of the lodging to be engaged. At the same time, the second cam portion 27 of the pull tab 20 can be inserted between the fastener elements of the fastener element row, so that the stop mechanism can be automatically actuated.

Further, in the slider 1 of the first embodiment, even if the slider 20 is rotated until the inclination angle of the tab 20 becomes a specific cam switching angle (for example, 100°), the first cam portion 26 of the tab 20 is brought into contact with each other. The left and right side wall portions 32 of the outer cover member 30 are attached to the outer cover member 30 against the urging force of the elastic deformation portion 36. Therefore, when the grip portion 22 of the pull tab 20 is released, the pressing force generated by the elastic deformation portion 36 of the cover member 30 can be applied to the first cam portion 26, so that the pull tab 20 can be stably poured toward the meshing opening side. .

Further, when the slider 20 is rotated to the second rotation range which is the inclination angle equal to or higher than the cam switching angle, for example, as shown in FIG. 10, the slider 20 is placed on the upper surface of the engagement opening side with respect to the upper blade 11. When the inclination is substantially 120°, the first cam portion 26 of the pull tab 20 is separated from the cover member 30, but the first cam portion 26 is separated from the cover member 30 or is about to leave. Before the cover member 30 is opened, the second cam portion 27 abuts against the upper wall portion 31 of the cover member 30 immediately after the first cam portion 26, and the cover member 30 can be lifted against the pressing force of the elastic deformation portion 36.

Further, when the inclination angle of the pull tab 20 is substantially 120°, the contact point P3 of the second cam portion 27 with respect to the cover member 30 is disposed in the longitudinal direction of the slider, and is disposed on the mounting shaft portion 21 of the pull tab 20. The position of the contact P2 contacting the upper surface of the upper blade 11 is further on the grip portion 22 side (rear side) of the pull tab 20 in the fallen state.

Therefore, the pulling piece 20 is released by releasing the grip portion 22 of the tab 20, and the pressing force of the elastic deformation portion 36 of the cover member 30 acts on the abutment point of the second cam portion 27 with respect to the cover member 30. Thereby, the rotation of the pull tab 20 toward the engagement opening side of the slider main body 10 is effectively promoted. Further, when the pull tab 20 is rotated toward the engagement opening side and the inclination angle of the pull tab 20 is equal to or less than the cam switching angle, the second cam portion 27 of the pull tab 20 is separated from the upper wall portion 31 of the cover member 30, and the first cam portion 26 is provided. Since the left and right side wall portions 32 of the cover member 30 are continuously contacted, the pressing force of the elastic deformation portion 36 of the cover member 30 can be applied to the first cam portion 26 again, so that the pull tab 20 can be stably poured toward the meshing port side.

Further, in the slider 1 of the first embodiment, for example, as shown in FIG. 11, the tab 20 is rotated by approximately 150° with respect to the upper surface of the engagement opening side of the upper blade 11. The second cam portion 27 of the pull tab 20 abuts against the upper wall portion 31 of the cover member 30 to lift the cover member 30 further, but the left and right leg portions 35 of the cover member 30 abut against the slider body 10 and then mount the post. The rocking restricting portion 16b of the 16 restricts the further rise of the outer cover member 30. At this time, the restricted position is limited to the second rotation range of the pull tab 20.

Thus, by restricting the rise of the cover member 30, the tab 20 is also restricted to rotate in such a manner that the angle of inclination of the tab 20 is greater than 150°, thereby preventing the tab 20 from being opposed to the upper surface of the engagement opening side of the upper blade 11. Rotate in a manner that is inclined more than 150°.

Moreover, in the slider 1 of the first embodiment, when the angle of inclination of the tab 20 is substantially 150°, the tab 20 is freed by releasing the grip portion 22 of the tab 20, and the cover member 30 is The pressing force of the elastic deformation portion 36 acts on the second cam portion 27, so that the pull tab 20 can be urged toward the slider The engagement of the engagement opening side of the main body 10 allows the pull tab 20 to effectively collapse toward the engagement opening side.

As described above, in the slider 1 of the first embodiment, since the first cam portion 26 and the second cam portion 27 having different protruding directions are disposed on the attachment shaft portion 21 of the tab 20, the first one is The cam portion 26 and the second cam portion 27 respectively urge the tab 20 to rotate in the lodging direction in the first rotation range and the second rotation range in which the inclination angles of the tabs 20 are different from each other, so that the tab 20 can be effectively Lodging.

Therefore, in the slider 1 of the first embodiment, the inclination angle of the tab 20 which can cause the tab 20 to fall toward the engagement opening side of the slider main body 10 can be made as compared with the slider having the stopper mechanism previously attached thereto. The range is set to be larger. Further, the first cam portion 26 and the second cam portion 27 of the pull tab 20 can be selectively brought into contact with the cover member 30 in accordance with the inclination angle of the pull tab 20, whereby the pressing force of the cover member 30 can be effectively performed. Acting on the pull tab 20, even if the pull tab 20 is rotated to a large tilt angle, the pull tab 20 can be stably stowed by releasing the pull tab 20.

The wide portion 71 of the cover member 70 is configured to have the same shape and size in the width direction as the front end portion of the upper blade 41 when the slider 2 is viewed in plan. In this case, the wall body 71a is a stopper that causes the left and right side frame portions 53 of the tab 50 to collide and stops the rotation of the tab 50, and prevents the tab 50 from being reversed. The rotation restricting portion (rotation preventing portion) that rotates in the direction of the inlet side functions. That is, in the slider 2 of the second embodiment, the tab 50 can be placed in the fallen state toward the engagement opening side of the slider main body 40 until the left and right frame portions of the pull tab 50 abut against the rotation restricting portion of the cover member 70. Rotate within the range of the state.

Next, a procedure for assembling the slider 2 of the second embodiment having the above-described constituent parts will be described.

First, the mounting shaft portion 51 of the pull tab 50 is attached to the left and right tab holding portions 47 of the slider main body 40. Specifically, the attachment shaft portion 51 of the tab 50 is inserted between the front and rear post portions 47a and 47b of the left and right tab holding portions 47, and thereafter, the upper end portions of the front and rear column portions 47a and 47b are adjacent to each other. The direction is pressed to cause plastic deformation. Thereby, the attachment shaft portion 51 of the pull tab 50 is rotatably held at a specific position by the left and right tab holding portions 47.

Then, in a state in which the tab 50 held by the tab holding portion 47 is undulated toward the engagement opening side as shown in FIG. 12, the stopper claw 60 of the tab pressing member is stopped to stop the claw. The elastic deformation portion 64 of the body 60 is disposed so as to be received in the accommodation groove 41a from the upper side of the slider body 40.

At this time, the positions of the first abutting portion 62a and the second abutting portion 62b of the stopping claw 60 are aligned with the positions of the first cam portion 56 and the second cam portion 57 of the tab 50, respectively. Position of the body 60, and stopping the stopping claw portion 61 of the stopping claw 60 via the claw hole of the slider body 40 41c enters the sprocket guiding path. Thereafter, the pressing portions 41b provided on the right and left sides of the upper blade 41 are pressed so as to be bent toward the inner side in the width direction of the slider. Thereby, the stopping claw 60 is attached to the slider body 40 by the pressing portion 41b, and the attachment shaft portion 51 of the tab 50 is rotatably disposed on the upper surface of the upper blade 41 and the stopping claw 60. between.

Next, the outer cover member 70 is covered by the upper 41 of the slider main body 40 to which the stopping claw 60 is attached. At this time, the left and right front fixing posts 45 and the rear fixing posts 46 disposed in the upper blade 41 are housed in the cover member 70, and the mounting shaft portion 51 of the pull tab 50 is disposed in the insertion hole 73 of the cover member 70. The cover member 70 is covered on the upper blade 41 in a manner as described above. At the same time, the left and right front fixing posts 45 and the rear fixing post 46 are brought into contact with the inner wall surface of the cover member 70. Thereby, the cover member 70 can be placed at a specific position of the upper blade 41.

After the cover member 70 is placed on the upper blade 41, the portion of the cover member 70 corresponding to the insertion hole portion 46a formed in the front fixing post 45 and the rear fixing post 46 is partially pressed from the outside to be recessed inside. . Thereby, a convex portion is formed on the inner wall surface of the outer cover member 70, and each convex portion is fitted into the corresponding insertion hole portion 46a formed in the front fixing post 45 and the rear fixing post 46. Thereby, the cover member 70 is fixed to the left and right front fixing posts 45 and the rear fixing post 46 at two locations, whereby the slider 2 of the second embodiment can be assembled.

The slider 2 of the second embodiment obtained in this manner can constitute a zipper by inserting the element rows of the left and right zipper tapes in the sprocket guiding path of the slider 2. Further, in the case of constituting the zipper, the slider 2 of the second embodiment can be stopped by, for example, as shown in Fig. 14, by pulling the tab 50 toward the engagement opening side of the slider body 40. The stop claw portion 61 enters the sprocket guide path of the slider main body 40, and the stop mechanism is actuated.

On the other hand, by pulling the grip portion 52 of the pull tab 50 with a finger, the pull tab 50 is pivoted about the mounting shaft portion 51 of the pull tab 50, as shown in FIG. The first cam portion 56 and the second cam portion 57 of the pull tab 50 are also rotated to change their orientation.

At this time, by the rotation of the first cam portion 56, the stopping claw 60 can be slowly lifted against the pressing force of the elastic deformation portion 64 of the stopping claw 60, so that the stopping claw 61 can be slid out. The sprocket guiding path of the body 40. Thereby, the slider 2 can be smoothly slid along the element rows.

Further, as shown in FIG. 15, when the handle 50 is rotated so as to be inclined by approximately 40 degrees with respect to the upper surface of the engagement opening side of the upper blade 41, the first cam portion 56 is opposed to the stop claw 60. The contact point of the abutting portion 62a is disposed at a position where the mounting shaft portion 51 of the pull tab 50 contacts the contact portion of the bottom surface portion of the tab holding portion 47 disposed on the upper surface of the upper blade 41, and is further lowered. The grip portion 52 side of the pull tab 50 (ie, the rear side).

Therefore, the pull-tab 50 is released by releasing the grip portion 52 of the pull-tab 50, and the pressing force of the elastic deformation portion 64 of the stop claw 60 acts on the first cam portion 56, and the first cam portion 56 is opposed to the first cam portion 56. The abutting point of the tab holding portion 47 exerts a force in a downward direction or a downward oblique direction, so that the tab 50 can be urged to rotate toward the engaging opening side of the slider main body 40, thereby causing the tab 50 to stably fall down.

Further, even in a state where the pull-tab 50 has been lowered to the engagement opening side of the slider main body 40, since the first cam portion 56 abuts against the tab holding portion 47, the tab 50 can be pushed from the stop claw 60. The lodging state of the pull tab 50 is stably maintained under pressure.

Further, in the slider 2 of the second embodiment, even if the slider 50 is rotated until the inclination angle of the tab 50 becomes a specific cam switching angle (for example, 60°), the first cam portion 56 of the tab 50 is brought into contact with each other. The first abutting portion 62a of the stopping claw 60 is lifted against the pressing force of the elastic deformation portion 64 to lift the stopping claw 60. Therefore, when the grip portion 52 of the tab 50 is released, the pressing force generated by the elastic deformation portion 64 of the stopping claw 60 can be applied to the first cam portion 56, and the tab 50 can be stably stabilized toward the engaging opening side. Lodging.

Further, when the slider 50 is rotated until the tilt angle becomes the second rotation range equal to or higher than the cam switching angle, the first cam portion 56 of the tab 50 is separated from the first abutting portion 62a of the stopping claw 60, but the first When the cam portion 56 is separated from the first abutting portion 62a or immediately before leaving the first abutting portion 62a, the second cam portion 57 abuts against the second abutting portion 62b of the stopping claw 60, thereby resisting elastic deformation. The pressing force of the portion 64 lifts the stopping claw 60.

In this case, the second cam portion 57 is disposed at a contact point with respect to the second abutting portion 62b. The mounting shaft portion 51 of the pull tab 50 contacts the contact point of the bottom surface portion of the tab holding portion 47 provided on the upper surface of the upper blade 41, and is further on the grip portion 52 side of the pull tab 50 in the fallen state (ie, Rear side).

Therefore, by pulling the grip portion 52 of the tab 50 to free the tab 50, the pressing force of the elastic deformation portion 64 of the stopping claw 60 can be applied to the second cam portion 57, thereby causing the tab 50 to slide. The rotation of the engaging body side of the main body 40. Further, when the pull tab 50 is rotated toward the engagement opening side and the inclination angle of the pull tab 50 is equal to or less than the cam switching angle, the second cam portion 57 of the pull tab 50 is separated from the second abutting portion 62b of the stop claw 60, and the first Since the cam portion 56 continuously abuts against the first abutting portion 62a of the stopping claw 60, the pressing force of the elastic deformation portion 64 of the stopping claw 60 can be applied to the first cam portion 56 again, thereby stabilizing the tab 50. The ground falls to the side of the meshing opening.

Further, in the slider 2 of the second embodiment, for example, as shown in FIG. 16, the tab 50 is rotated by approximately 90 degrees with respect to the upper surface of the engaging opening side of the upper blade 41. The left and right side frame portions 53 of the pull tab 50 are brought into contact with the rotation restricting portion (rear wall body 71a) of the cover member 70, thereby restricting the rotation of the pull tab 50, thereby preventing the tab 50 from being engaged with respect to the upper flap 41. The upper surface of the mouth side is rotated by more than 90°.

Further, in the slider 2 of the second embodiment, when the inclination angle of the tab 50 is substantially 90°, the slider 50 is freed by releasing the grip portion 52 of the tab 50, so that the claw 60 is stopped. The pressing force of the elastic deformation portion 64 acts on the second cam portion 57, so that the rotation of the tab 50 toward the engagement opening side of the slider main body 40 can be promoted, so that the pull tab 50 can effectively fall toward the engagement opening side.

As described above, in the slider 2 of the second embodiment, similarly to the slider 2 of the first embodiment, the first cam portion 56 in which the protruding directions are different from each other is disposed on the mounting shaft portion 51 of the tab 50. Since the first cam portion 57 and the second cam portion 57 can respectively urge the pull tab 50 to fall in the first rotation range and the second rotation range in which the inclination angles of the pull tabs 50 are different from each other. The rotation of the direction causes the pull tab 50 to effectively fall down.

Moreover, the first convex portion of the pull tab 50 can be made according to the magnitude of the tilt angle of the pull tab 50. The wheel portion 56 and the second cam portion 57 selectively abut against the cover member 70, so that the pressing force of the cover member 70 is effectively applied to the pull tab 50, so that even if the pull tab 50 is rotated to a large inclination angle, Release the pull tab 50 to stabilize the pull tab 50.

Further, the sliders 1 and 2 of the first embodiment and the second embodiment are configured such that when the sliders 1 and 2 are not slid, the pressing force of the slider pressing member is pulled. The sheets 20, 50 are automatically turned to the engagement side of the slider bodies 10, 40 while maintaining the lodging state of the tabs 20, 50. However, in the present invention, the slider can also be configured in such a manner that, when the sliding operation is not performed, the pull tab is automatically tilted toward the inlet side of the slider body by the pressing force of the tab pressing member. The lodging state of the pull tab is maintained.

Further, according to the first and second embodiments described above, the rotation restricting portion is provided to prevent the tabs 20 and 50 from rotating beyond the second rotation range. However, in the present invention, the tab can be rotated beyond the second rotation. The manner of the range constitutes a slider. In this case, the slider is rotated to a lodging position (second lodging position) in a direction opposite to the lodging position (first lodging position) where the first and second cam portions are pressed and collapsed. In other words, in the present invention, the slider can be configured such that the slider can be placed at the first lodging position where the slider body is tilted toward the engagement opening side, and the second panel is lowered to the inlet side of the slider body. Rotate within the range of the lodging position.
