Description

slider

The present invention relates to a slider for a slide fastener, and more particularly, to a slider capable of automatically pulling down a handle and maintaining a collapsed state of the handle when the slider is not slid.

Conventionally, a slide fastener is attached to an opening of an article such as clothing or a bag, and a slider attached to the slide fastener is slid along the element row to engage or separate the left and right element rows. The opening can be opened and closed. A slider for a slide fastener generally has a slider body and a handle rotatably held with respect to the slider body, and the left and right element rows are guided between the upper and lower blades of the slider body. A substantially Y-shaped element guide path is formed.

Further, as one of such sliders, when the slider is stopped at an arbitrary position on the element row in the slide fastener, a stop claw portion is projected into the element guide path of the slider body, and the stop claw portion There is known a slider provided with a stop mechanism that can hold the slider at a stop position of the element row by engaging between the fastener elements of the element row and engaging with the element row.

For example, Japanese Unexamined Patent Application Publication No. 2009-61184 (Patent Document 1) discloses a slider with a stop mechanism in which two stop claws are integrally formed on a rotation shaft portion (attachment shaft portion) of a handle.
In the slider of Patent Document 1, when the handle is raised with a finger to operate the slider, two stop claws formed on the rotation shaft of the handle are pulled out from the element guide path of the slider body. Can be smoothly slid along the element row.

On the other hand, when the finger is released from the handle after the operation of the slider is finished, the handle rotates so as to fall down to the rear opening side of the slider body due to its own weight, whereby the stop pawl portion of the handle comes into contact with the element row. In this state, for example, the left and right fastener stringers receive a lateral pulling force and the slider is forcibly moved in the opening direction of the element rows, so that the two stop claws provided on the puller are connected between the fastener elements of each element row. The stop pawl portions are locked to the element rows. Thereby, the forced movement of the slider can be stopped, and the stopped state of the slider can be held (locked).

Further, for example, in Japanese Patent Application Laid-Open No. 2007-111351 (Patent Document 2), there is a stop mechanism with a stop claw provided on a cover member that holds the rotation shaft portion of the handle between the upper blade of the slider body. A slider is disclosed.

In the slider of this Patent Document 2, an elastic piece that can be elastically deformed is arranged on the cover member. Further, the cover member is swingably attached to the front and rear mounting pillars erected on the upper blade so as to sandwich the rotary shaft portion of the handle between the slider member and the upper blade. In the slider of Patent Document 2 having such a cover member, when the handle is pulled with a finger to operate the slider, the cover member is lifted against the urging force of the elastic piece portion. The stop pawl is pulled out from the element guide path of the slider body. Thereby, the slider can be smoothly slid along the element row.

On the other hand, when the finger is released from the handle after the operation of the slider, the elastic piece of the cover member is elastically restored to return the cover member to its original position (lowering), and the stop claw portion disposed on the cover member Is advanced into the element guide path of the slider body, and is locked between the fastener elements in the element row. Thereby, the stop state of the slider can be held (locked).

Also, some sliders have a function that can automatically rotate the handle so that it falls on the slider body after the operation of the slider is completed, and maintain the pulling state. Yes. Examples of such a slider are disclosed in Japanese Patent Laid-Open No. 3-295502 (Patent Document 3), International Publication No. 2012/042620 (Patent Document 4), and the like.

For example, a slider described in Patent Document 3 includes a slider body, a handle rotatably supported by the slider body via a shaft portion, a stop claw body having a claw portion at one end, and a stop claw body And a first spring member that urges the stop pawl body and a second spring member (hinge spring) that urges the puller in a lying state.

The slider body of Patent Document 3 has upper and lower blades and guide columns that connect the front end portions of the upper and lower blades, and a substantially Y-shaped element guide path is formed between the upper and lower blades. ing. A handle attachment portion for attaching a handle is formed on the upper wing plate, and a shaft portion inserted through the insertion hole of the handle is attached to the handle attachment portion. A cam portion that comes into contact with the stop claw body is disposed at one end of the handle.

The stop claw body is swingably attached to the slider body. Further, the stop claw body receives an urging force from the first spring member to cause the claw portion to protrude into the element guide path of the slider body, and the pulling force passes through the cam portion by the urging force received by the stop claw body. It is energized towards the lying state. On the other hand, when the handle is operated, the stop claw body is lifted against the urging force of the first spring member by the cam portion of the handle, thereby allowing the claw portion to be extracted from the element guide path. It becomes.

Furthermore, in the slider of Patent Document 3, the second spring member, which is a member different from the first spring member, is arranged on the puller or the slider body so as to urge the puller toward the lying down state. In such a slider of Patent Document 3, for example, even when the claw portion of the stop claw interferes with the fastener element when it stops with respect to the element row, the second spring member can pull the handle even if the claw portion cannot sufficiently enter the element guide path. Can be held in a lying state. Thereby, since it is possible to prevent the handle from swinging freely when the handle is not operated, it is possible to make it difficult for the handle to catch on other articles, and it is also possible to prevent the appearance of the product from being deteriorated due to the shaking of the handle.

Further, Patent Document 4 describes a slider that has a simplified structure and is reduced in size and weight compared to the slider of Patent Document 3 as 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 includes a slider body 110, a handle 120 rotatably held by the slider body 110, a spring member 130 having a stop claw portion 131, and a cover body 140 fixed to the slider body 110. Have

The slider body 110 has upper and

lower blades

111 and 112 and a guide column 113 that connects the front end portions of the upper and

lower blades

111 and 112. A front mounting column 111 a and a rear mounting column 111 b for mounting the cover body 140 are erected on the front end portion and the rear end portion on the upper surface of the upper blade 111. Between the front mounting column 111a and the rear mounting column 111b, there is provided an insertion portion 111c into which the mounting shaft portion 121 disposed at one end of the handle 120 is inserted. The cover 140 is fixed to the front mounting column 111a and the rear mounting column 111b in a state where the mounting shaft portion 121 of the handle 120 is inserted into the insertion portion 111c, so that the mounting shaft portion 121 of the handle 120 is fixed to the upper blade plate. 111 and the cover body 140 are held.

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

The handle 120 has a flat tab 122, a pair of left and right legs 123 extending from the knob 122, and a mounting shaft 121 that is horizontally mounted between the tip ends of the pair of legs 123. A handle opening 124 having a substantially rectangular shape is formed by being surrounded by the knob 122, the pair of legs 123, and the mounting shaft 121.

A cam portion 125 having a form protruding toward the pulling opening 124 is disposed at a substantially central portion in the slider width direction of the mounting shaft portion 121. In addition, left and right abutting portions 126 that extend toward the handle opening portion 124 and abut against the cover body 140 are disposed at the connecting portion between the leg portion 123 and the mounting shaft portion 121.

The spring member 130 branches upward from a main body part 132 straddling the cam part 125 of the handle 120, a stop claw part 131 suspended from the rear end of the main body part 132, and a bent part on the rear side of the main body part 132. It has the elastic piece part 133 extended.

The cover body 140 includes a substantially rectangular ceiling 141, left and right side walls 142 suspended from the side edges of the ceiling 141, a front wall 143 suspended from the front and rear ends of the ceiling 141, and And a rear wall 144. An accommodation 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 ceiling portion 141.

A cover opening 146 that opens from the lower edge to the ceiling 141 is formed in the left and right side wall portions 142 of the cover body 140, and the mounting shaft portion 121 of the handle 120 is accommodated in the cover opening 146. The In this case, the front surface portion disposed on the front side of the peripheral surface facing the cover opening 146 in the left and right side wall portions 142 abuts the abutment portion 126 of the pull handle 120 to restrict the rotation range of the pull handle 120. It is comprised as the control part 147 to do.

When assembling the slider 100 of Patent Document 4 having the members as described above, the mounting shaft portion 121 of the handle 120 is inserted between the front and

rear mounting columns

111a and 111b on the upper surface of the upper wing plate 111 of the slider body 110. To place the handle 120. Further, the spring member 130 is disposed on the upper wing plate 111 on which the handle 120 is placed. At this time, the spring member 130 is disposed so that the main body portion 132 straddles the cam portion 125 of the handle 120 and contacts the cam portion 125.

Next, the cover body 140 is attached to the slider body 110. At this time, the cover body 140 is put on a predetermined position of the upper wing plate 111, and then the left and right side wall portions 142 of the cover body 140 are pressed inward to be plastically deformed, whereby the cover body 140 is moved to the slider. The body 110 is fixed to the front and rear mounting

posts

111a and 111b. As the cover body 140 is fixed to the slider body 110 in this way, the handle 120 is moved from the state where the handle body 120 lies down to the rear opening side of the slider body 110 with the mounting shaft portion 121 as the center, to the restriction portion 147 of the cover body 140. Attached so as to be freely rotatable in the range up to the state where it abuts and stands up.

Such a slider 100 of Patent Document 4 simplifies the slider structure as compared with the slider of Patent Document 3, for example, and the slider 100 can be assembled relatively easily. Further, the urging force of the spring member 130 can be applied to the cam portion 125 of the pull handle 120, so that the stop claw portion 131 of the spring member 130 is moved, for example, in a state where the pull handle 120 has fallen to the rear opening side of the slider body 110. It is possible to enter the element guide path, engage with the element row, and keep the slider 100 stopped with respect to the element row.

Further, when the handle 120 is operated to stand up from the lying state, the cam portion 125 of the handle 120 lifts the spring member 130 upward against the urging force of the elastic piece portion 133 of the spring member 130. The stop pawl 131 exits from the element guide path. Therefore, the slider 100 can be smoothly slid along the element row.

Furthermore, in the slider 100 of Patent Document 4, since the cam portion 125 of the handle 120 can be biased by the spring member 130, the handle 120 can be rotated so as to lie down on the rear mouth side. Therefore, for example, when the finger is released from the knob portion 122 of the pull handle 120 after the operation of the slider 100 is completed, the pull handle 120 can be automatically rotated to the rear mouth side by the urging force of the spring member 130 and fall down. Thus, the stop claw 131 of the spring member 130 can enter the element guide path and automatically operate the stop mechanism.

JP 2009-61184 A JP 2007-111351 A JP-A-3-295502 International Publication No. 2012/042620 Pamphlet

In the sliders described in Patent Document 1 and Patent Document 2, when the slider is not operated, the puller freely swings and hangs with respect to the slider body, so that the appearance may deteriorate or the puller may be disturbed. there were. In addition, if the handle is hanging, the handle may be caught by another article, and there is a possibility that an article to which the slide fastener is attached or another article to which the handle is caught may be damaged.

On the other hand, in the slider described in Patent Document 3, by releasing the finger from the handle after the operation of the slider is finished, the handle is laid down by the biasing force of the first spring member and the second spring member, and further, It is possible to maintain a lying state. For this reason, like the sliders of Patent Document 1 and Patent Document 2, it is possible to prevent the handle from hanging.

However, the slider of Patent Document 3 requires two elastic members, a first spring member and a second spring member. For this reason, the number of parts of the slider is increased, and the cost of the slider is increased.

Further, in the slider of Patent Document 3, for example, when a coiled elastic member is used for the first spring member and the second spring member, the handle is grasped with a finger and 90 ° with respect to the upper surface of the rear side of the slider body. If the finger is released from the handle, the urging force of the first spring member and the second spring member can act on the puller, and the puller can fall on the rear opening side of the slider body. However, if coil-like elastic members are used for the first spring member and the second spring member in this way, the cost of the slider is further increased, and the assembly work of the slider becomes complicated.

On the other hand, Patent Document 3 discloses that a first spring member and a second spring member do not use a coil-like elastic member, but a leaf spring-like elastic member or an elastic member obtained by bending a leaf spring into a predetermined shape (hereinafter, referred to as “a spring member”). A slider constituted by using these elastic members (abbreviated as leaf spring-like elastic members) is also described as one example.

By using such a plate spring-like elastic member for the first spring member and the second spring member, it becomes possible to simplify the assembling work of the slider as compared with the case of using a coil-like elastic member. . However, in a slider using such a leaf spring-like elastic member, the handle is laid down in a predetermined direction (for example, a direction in which the handle is laid down toward the rear opening side of the slider body) by the urging force of the first spring member and the second spring member. The inclination angle of the pullable handle can be limited to a narrow range.

For this reason, for example, when the handle is tilted to an angle exceeding the range, the tilted state of the handle is held by the biasing force of the first spring member or the second spring member, or the handle is in a direction opposite to the predetermined direction. (For example, the direction of lying down on the shoulder side of the slider body) may lie down, and as a result, there is a possibility that the handle feels in the way or gets caught by other articles.

In the slider 100 described in Patent Document 4, the range of the rotatable angle of the pull handle 120 is limited in advance by the restricting portion 147 of the cover body 140, and by releasing the finger from the pull handle 120 within the angular range, The cam portion 125 of the puller 120 receives the biasing force of the spring member 130 and causes the puller 120 to lie down in a predetermined direction (a direction to lie down on the rear side of the slider body).

Such a slider 100 of Patent Document 4 does not use a coil-shaped elastic member, and the assembly work of the slider 100 is 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 restricting portion 147 is provided on the cover body 140, the range of the rotatable angle of the pull handle 120 is relatively small, so that it is difficult to perform the sliding operation of the slider 100. There was a fear. For this reason, it has been desired to improve the operability of the slider 100 by increasing the range of the tilt angle in which the handle 120 can fall down.

Further, in the slider 100 of Patent Document 4, when the inclination angle of the handle 120 with respect to the upper surface on the rear opening side of the upper blade 111 increases, the magnitude of the urging force that the cam portion 125 of the handle 120 receives from the spring member 130 tends to decrease. It was in. For this reason, even when the inclination angle of the pull handle 120 is large, it has been desired that the biasing force of the spring member 130 is appropriately applied to the cam portion 125 of the pull handle 120 in order to stably fall the pull handle 120.

The present invention has been made in view of the above-described conventional problems. A specific object of the present invention is to automatically tilt the handle when the slider is not slid to maintain the collapsed state of the handle. It is an object of the present invention to provide a slider capable of setting a large rotation range of a puller.

In order to achieve the above object, a slider provided by the present invention has, as a basic configuration, a slider body in which shoulder-edge ends of upper and lower blades are connected by a guide post, and at least a part of an elastically deformable portion. And a handle biasing member that is swingably attached to the slider body, and is rotatably held via an attachment shaft portion disposed between the upper surface of the upper blade and the handle biasing member. And the attachment shaft portion of the handle has a cam portion that contacts the pulling biasing member, and the pulling biasing member elastically deforms the elastic deformation portion by the operation of the pulling handle, And a slider for a slide fastener that causes the handle to fall down via the cam portion by elastic return of the elastic deformation portion, wherein the cam portion protrudes from the attachment shaft portion of the handle. And said The from the mounting shaft portion of the hand the first cam portion is for the most important feature to become a second cam portion projecting in different directions.

In the slider according to the present invention, the first cam portion contacts the pulling biasing member when the pulling portion rotates in a first rotation range until a predetermined cam switching angle is reached, and the second cam portion is When the puller rotates in a second rotation range equal to or greater than the cam switching angle, the pulling member is at least in contact with the pulling biasing member, and the first cam portion is in contact with the first rotation range. The second cam portion is configured to receive a biasing force from the pulling member biasing member that is in contact with the second rotation range. It is preferable to have a form that promotes rotation in the fall direction of the pulling handle.

Further, it is preferable that the slider according to the present invention has a rotation restricting portion that restricts the rotation range of the handle and determines the upper limit of the second rotation range. In this case, it is preferable that the rotation restricting portion is configured by a swing restricting portion that is disposed on the slider body and restricts the swing range of the pull biasing member by contacting the pull biasing member. .

According to the present invention, there is provided a cover member that covers the pulling biasing member and is fixed to the slider body, and the rotation restricting portion contacts the pulling of the cover member to stop the rotation of the pulling hand. You may be comprised by the stop part.

Furthermore, in the slider according to the present invention, the pulling biasing member is constituted by a single member, and a first abutting portion that abuts the first cam portion and a second cam portion abuts. It is preferable to have a 2nd contact part.
In this case, the first cam part and the second cam part are arranged at different positions in the direction along the axis of the mounting shaft part, and the first contact part and the second contact part are: It is particularly preferable that the pulling biasing member is provided at a different position.

In addition, it is preferable that the protruding direction of the second cam portion from the mounting shaft portion is inclined toward the pulling-down direction side of the first cam portion from the protruding direction of the mounting shaft portion.

Further, in the slider according to the present invention, the first cam portion has a contact point of the first cam portion with respect to the pulling biasing member when the slider is viewed from the side surface side in the first rotation range. It is preferable that the attachment shaft portion of the handle has a form arranged on the knob portion side of the handle in a lying state rather than a contact point in contact with the upper surface of the upper blade.

Further, when the slider is viewed from the side surface side in the second rotation range, the second cam portion has a contact point of the second cam portion with the pulling biasing member so that the attachment shaft of the pulling handle is attached. It is preferable that the portion is arranged on the side of the handle portion in the lying state rather than the contact point that contacts the upper surface of the upper blade.

In the slider of the present invention, a claw hole is formed in the upper wing plate, and the second cam portion is inserted into the substantially Y-shaped element guide path disposed between the upper and lower wing plates of the slider body. It is preferably configured as a stop claw portion that can be advanced and retracted through the hole.
On the other hand, in the slider of the present invention, a claw hole is formed in the upper wing plate, and the pulling biasing member is inserted into the substantially Y-shaped element guide path disposed between the upper and lower wing plates of the slider body. You may have the stop nail | claw part which can be advanced / retreated via a nail | claw hole.

The slider of the present invention rotates through a slider body, a pulling biasing member having an elastically deforming portion at least in part, and an attachment shaft portion disposed between the upper blade plate of the slider body and the pulling biasing member. The handle has at least a handle that can be held, and the handle has two types, a first cam portion protruding from the mounting shaft portion and a second cam portion protruding from the mounting shaft portion in a direction different from the first cam portion. A cam portion is provided.

According to the slider of the present invention configured as described above, the first cam portion and the second cam portion that protrude from the attachment shaft portion of the pull handle in different directions, so that the pull angle of the pull handle is within a range different from each other. It is possible to steadily fall down the pull handle by promoting rotation in the fall direction.

For this reason, in the slider of the present invention, by appropriately setting the projecting directions of the first and second cam portions, the shape of the cam surface, and the like, for example, the inclination angle of the handle with respect to the upper surface on the rear opening side of the upper blade is 90 °. Even when the angle is larger, or even when the angle is 120 ° or more, the first cam portion of the handle is brought into contact with the handle biasing member, or the second cam portion and the first cam portion of the handle are biased. By selectively abutting the member continuously, the handle can be laid down on the rear opening side of the slider body.

That is, the slider according to the present invention has an inclination angle of the handle that allows the handle to lie down on the rear opening side of the slider body as compared with, for example, the conventional sliders described in Patent Document 3 and Patent Document 4. The range can be set larger, and thereby the operability of the slider can be improved.

In addition, in the slider of the present invention, the first cam portion and the second cam portion of the handle are selectively brought into contact with the handle biasing member according to the inclination angle of the handle, and the elastically deforming portion of the handle biasing member. Therefore, the urging force of the pulling urging member can be effectively applied to the puller regardless of the inclination angle of the puller, and the puller can be stably laid down.

In particular, in the present invention, the first cam portion of the handle is used as a handle biasing member in a first rotation range from the state where the handle has fallen down until the tilt angle of the handle with respect to the upper surface of the upper blade plate reaches a predetermined cam switching angle. It is comprised so that it may contact | abut, and the 2nd cam part of a handle is comprised so that the inclination angle of a handle may contact | abut at least a handle urging | biasing member in the 2nd rotation range beyond a cam switching angle.

In other words, the first cam portion is disposed so as to be able to contact the pulling member biasing member in a first rotation range in which the tilting angle of the pulling handle is 0 ° at which the pulling handle is completely laid down to a predetermined cam switching angle or less. Yes. Further, the second cam portion is disposed so as to be able to contact at least the pulling force urging member in the second rotation range in which the tilt angle of the handle is from the cam switching angle or more to the upper limit of rotation. Note that the second cam portion may be disposed so as to be able to contact the pulling biasing member from a range where the tilt angle of the pulling handle is smaller than the cam switching angle. In the present invention, the cam switching angle can be set to an arbitrary magnitude.

Further, the first cam portion and the second cam portion receive a biasing force from a pulling biasing member with which the first cam portion and the second cam portion contact in the first rotation range and the second rotation range, respectively. It has a form that promotes rotation in the lying down direction.

Since the first cam portion and the second cam portion of the handle are configured in this way, the first cam portion and the second cam portion are selectively brought into contact with the pulling biasing member, and the pulling handle is lowered. Can be more stably promoted, and the range of the angle of inclination of the handle that can tilt the handle can be expanded to two ranges of the first rotation range and the second rotation range.

Also, the slider of the present invention has a rotation restricting portion that restricts the rotation range of the handle and determines the upper limit of the second rotation range. As a result, the first cam portion or the second cam portion of the handle can be stably brought into contact with the handle biasing member within the rotation range of the handle regulated by the rotation regulating portion. It is possible to cause the puller to fall down by smoothly applying the urging force of the puller to the puller.

In this case, the rotation restricting portion is arranged on the slider body, and is configured by a swing restricting portion that restricts the swing range of the pull biasing member by contacting the pull biasing member. By providing such a swing restricting portion to restrict the swing range of the pulling biasing member, the rotation restricting portion can be easily configured, and the rotation upper limit of the pulling handle can be set stably.

In addition, the slider of the present invention has a cover member that covers the pulling biasing member and is fixed to the slider body, and the rotation restricting portion collides with the pulling of the cover member to stop the rotation of the pulling portion. It may be constituted by. Such a pulling contact portion of the cover member also makes it possible to easily configure the rotation restricting portion, and to stably set the rotation upper limit of the pulling handle.

Furthermore, in the slider of the present invention, the pulling biasing member is constituted by a single member, and a first contact portion for contacting the first cam portion and a second contact for contacting the second cam portion. A contact portion. Thereby, since the number of parts can be reduced and the slider can be configured, the manufacturing cost of the slider can be reduced and the assembling work of the slider can be simplified.

In this case, the first cam portion and the second cam portion of the handle are arranged at different positions in the direction along the axis of the attachment shaft portion, and the first contact portion and the second contact portion are Provided at different positions of the pulling biasing member corresponding to the positions of the first cam portion and the second cam portion, respectively. Accordingly, the first cam portion and the second cam portion can be selectively and smoothly brought into contact with the pulling biasing member depending on the inclination angle of the pulling handle. Can be promoted more stably.

Further, in the slider of the present invention, the protruding direction of the second cam portion from the mounting shaft portion is inclined more toward the collapse direction of the pulling handle than the protruding direction of the first cam portion from the mounting shaft portion. As a result, even if the puller rotates to the second rotation range that is larger than the first rotation range in which the first cam portion contacts the pulling biasing member and can tilt the pulling handle, Since the urging force of the pulling member urging member can be effectively applied to the puller by making the cam part contact, the rotation of the puller in the falling direction can be promoted, and the puller can be stably laid down.

Furthermore, in the slider of the present invention, the first cam portion has a pulling biasing member of the first cam portion when the slider is viewed from the side surface in a first rotation range in which the tilt angle of the handle is equal to or less than the cam switching angle. The contact point with respect to the handle has a configuration in which the handle attachment shaft portion is arranged closer to the handle portion (grip portion) in the lying state than the contact point where the upper shaft of the upper blade is in contact. As a result, when the first cam portion is brought into contact with the pulling biasing member and the biasing force of the pulling biasing member is applied to the first cam portion, the pulling handle in the direction of falling to the rear opening side of the slider body is formed. Rotation can be promoted stably.

Here, the contact point of the first cam portion is arranged closer to the handle knob portion in the lying state than the contact point between the attachment shaft portion of the handle and the upper blade plate. For example, the handle is arranged along the slider width direction. When the rotation is performed using the mounting shaft as a rotating shaft, the contact point is arranged on the side where the handle is tilted with respect to the slider length direction with respect to the contact point between the handle mounting shaft and the upper blade. .

Thereafter, the cover member 30 is pushed into the front mounting column 15 from above, so that the elastically deforming portion 36 of the cover member 30 is further inserted while elastically contacting the groove bottom portion of the housing concave groove portion 15d, and the left and right arms of the cover member 30 are also inserted. The portion 33 is lowered to the position of the fitting portion 15b of the front mounting column 15 while contacting the outer 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 cover member 30 are lowered while being elastically deformed so as to gradually expand outward in the width direction by the outer inclined surface of the locking head portion 15a. Further, since the front end edges of the left and right arm portions 33 of the cover member 30 are in contact with the front bulging portion 15c of the front mounting column 15, the cover member 30 is lowered while being guided to a predetermined 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 column 15.

Then, the left and right arm portions 33 of the cover member 30 move beyond the locking head portion 15a of the front mounting column 15 to the position of the fitting portion 15b, whereby the arm portion 33 and the side wall portion 32 of the cover member 30 are elastically restored. Thus, the left and right engaging portions 34 of the cover member 30 can be engaged with the engaged portions 11 b provided at the front end portion of the upper wing plate 11 while being fitted into the fitting portion 15 b of the front mounting column 15. At the same time, the mounting shaft portion 21 of the handle 20 is inserted into the insertion recess 32 a of the cover member 30, and the mounting shaft portion 21 can rotate between the upper surface of the upper blade 11 and the left and right side wall portions 32 of the cover member 30. Retained.
By performing the above assembling work, the slider 1 of the first embodiment shown in FIG. 1 is assembled.

The slider 1 of the first embodiment obtained in this way can constitute a slide fastener by inserting the element rows of the left and right fastener stringers through the element guide path of the slider 1. Further, when the slide fastener is configured, the slider 1 of the first embodiment, for example, as shown in FIGS. 3 and 4, the handle 20 is laid down on the rear opening side of the slider body 10 to pull the handle engaging / disengaging portion 17. By engaging with the second cam portion 27, the second cam portion 27 functioning as a stop claw portion can enter the element guide path of the slider body 10, and the stop mechanism can be operated.

On the other hand, the slider 1 is shown in, for example, FIG. 9 by holding the knob portion 22 of the handle 20 with a finger and rotating the handle 20 so as to rise around the attachment shaft portion 21 of the handle 20. In this manner, the first cam portion 26 and the second cam portion 27 of the handle 20 can also be rotated to change their directions.

At this time, the rotating first cam portion 26 gradually lifts 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 is moved from the element guide path of the slider body 10. Can be withdrawn. Thereby, the slider 1 can be smoothly slid along the element row.

For example, as shown in FIG. 9, when the handle 20 is rotated so as to be inclined at approximately 60 ° with respect to the upper surface on the rear opening side of the upper wing plate 11, the contact of the first cam portion 26 against the cover member 30 is performed. The contact P1 is arranged closer to the knob 22 side (rear side) of the handle 20 in the lying state than the position of the contact P2 where the attachment shaft portion 21 of the handle 20 contacts the upper surface of the upper blade 11 in the slider length direction. ing.

For this reason, when the finger is released from the knob portion 22 of the handle 20 and the handle 20 becomes free, the urging force by the elastic deformation portion 36 of the cover member 30 acts on the first cam portion 26, and the first cam portion 26. Since a downward or obliquely downward force is applied to the contact point P <b> 1 with respect to the cover member 30, rotation of the puller 20 is urged toward the rear opening side of the slider body 10, and the puller 20 is stably laid down. be able to.

In the slider 1 according to the first embodiment, since the handle engaging / disengaging portion 17 is erected on the upper blade 11, the puller 20 is moved in the lying down direction by using the urging force of the elastic deformation portion 36 of the cover member 30. Even if the handle 20 is rotated, the handle 20 is prevented from falling down until it comes into contact with the handle engaging / disengaging portion 17 and the tilt angle of the handle 20 becomes 0 °.

In the first embodiment, when the puller 20 falls down until it comes into contact with the puller engagement / disengagement part 17, the urging force of the elastic deformation part 36 acts on the first cam part 26. The 2nd cam part 27 used as a stop nail | claw part will be in the state which contact | connected on the element row | line | column of a fastener stringer.

For this reason, for example, the second cam portion 27 is caused to enter the element guide path of the slider body 10 by pressing the handle 20 toward the handle engaging / disengaging portion 17 to be engaged with the handle engaging / disengaging portion 17. Therefore, the stop mechanism can be actuated. Thus, by operating the stop mechanism and locking the slider 1 with respect to the element row, a high lock strength (stop holding force) can be obtained.

Further, in a state in which the puller 20 has fallen to an angle at which the puller 20 comes into contact with the puller engagement / disengagement portion 17 and the second cam portion 27 is in contact with the element row, for example, the left and right fastener stringers receive a lateral pulling force and By forcibly moving in the opening direction, the second cam portion 27 of the handle 20 also moves in accordance with the relative movement of the element row with respect to the slider 1, so that the handle 20 further rotates in the direction of lying down and pulls the handle. At the same time, the second cam portion 27 of the handle 20 is fitted between the fastener elements of the element row, and the stop mechanism can be automatically operated.

Further, in the slider 1 according to the first embodiment, even if the handle 20 is rotated until the inclination angle of the handle 20 reaches a predetermined cam switching angle (for example, 100 °), the first cam portion 26 of the handle 20 is attached to the cover member 30. The cover member 30 is lifted against the urging force of the elastic deformation portion 36 by being brought into contact with the left and right side wall portions 32. For this reason, when the finger is released from the knob portion 22 of the handle 20, the urging force by the elastic deformation portion 36 of the cover member 30 acts on the first cam portion 26, and the handle 20 is stably tilted to the rear mouth side. be able to.

Further, when the handle 20 is rotated to the second rotation range having an inclination angle greater than the cam switching angle, for example, as shown in FIG. 10, the handle 20 is approximately 120 ° with respect to the upper surface on the rear opening side of the upper blade plate 11. When the first cam portion 26 of the handle 20 is separated from the cover member 30 when rotated so as to incline, the second cam portion is removed at the same time as the first cam portion 26 is separated from the cover member 30 or immediately before it is separated from the cover member 30. 27 comes into contact with the upper wall portion 31 of the cover member 30 following the first cam portion 26, and the cover member 30 can be lifted against the urging force of the elastic deformation portion 36.

When the angle of inclination of the handle 20 is approximately 120 °, the contact point P3 of the second cam portion 27 with respect to the cover member 30 is in the slider length direction, and the mounting shaft portion 21 of the handle 20 is It is arranged on the side of the knob 22 (rear side) of the handle 20 in the lying state rather than the position of the contact P2 in contact with the upper surface.

For this reason, when the finger 20 is released from the knob 22 of the pull handle 20 and the pull handle 20 becomes free, the urging force of the elastic deformation portion 36 of the cover member 30 acts on the contact point of the second cam portion 27 with respect to the cover member 30. Thus, the rotation of the handle 20 is effectively promoted to the rear opening side of the slider body 10. Furthermore, when the handle 20 rotates toward the rear opening side and the inclination angle of the handle 20 becomes equal to or smaller than the cam switching angle, the second cam portion 27 of the handle 20 is separated from the upper wall portion 31 of the cover member 30 and the second Since the one cam portion 26 continuously contacts the left and right side wall portions 32 of the cover member 30, the urging force of the elastic deformation portion 36 of the cover member 30 acts again on the first cam portion 26, and the handle 20 is moved to the rear opening side. Can be stably laid down.

Furthermore, in the slider 1 of the first embodiment, for example, as shown in FIG. 11, the handle 20 is rotated by tilting the handle 20 so as to be inclined at about 150 ° with respect to the upper surface on the rear opening side of the upper blade 11. Although the second cam portion 27 comes into contact with the upper wall portion 31 of the cover member 30 and the cover member 30 is further lifted, the left and right leg portions 35 of the cover member 30 are the swing restricting portions 16b of the rear mounting column 16 in the slider body 10. The cover member 30 is further prevented from rising. At this time, the regulated position is regulated within the second rotation range of the handle 20.

By restricting the lift of the cover member 30 in this manner, the rotation of the handle 20 is also regulated so that the inclination angle of the handle 20 is larger than 150 °. It is possible to prevent rotation with an inclination exceeding 150 ° with respect to the mouth side upper surface.

In the slider 1 according to the first embodiment, when the tilt angle of the handle 20 is approximately 150 °, the finger 20 is released from the knob 22 of the handle 20 and the handle 20 becomes free, so that the cover member 30 is elastically deformed. Since the urging force of the portion 36 acts on the second cam portion 27, it is possible to promote the rotation of the handle 20 toward the rear opening side of the slider body 10, and to effectively lie down the pulling handle 20 toward the rear opening side.

As described above, in the slider 1 according to the first embodiment, the first cam portion 26 and the second cam portion 27 having different projecting directions are arranged on the mounting shaft portion 21 of the handle 20. The cam portion 26 and the second cam portion 27 urge the rotation of the puller 20 in the fall direction in the first rotation range and the second rotation range where the inclination angles of the puller 20 are different from each other, and effectively pull down the puller 20. Can be made.

For this reason, in the slider 1 of the first embodiment, the range of the inclination angle of the handle 20 that allows the handle 20 to fall on the rear opening side of the slider body 10 is larger than that of the conventional slider with a stop mechanism. Can be set. Further, the first cam portion 26 and the second cam portion 27 of the pull handle 20 are selectively brought into contact with the cover member 30 according to the inclination angle of the pull handle 20, and the biasing force of the cover member 30 is effectively applied to the pull handle 20. Therefore, even if the handle 20 is rotated to a large inclination angle, the handle 20 can be stably laid down if the finger is removed from the handle 20.

FIG. 12 is an exploded perspective view illustrating a state in which the slider according to the second embodiment is disassembled. FIG. 13 is a perspective view showing a pull handle and a pull bias member of the slider.

The wide portion 71 of the cover member 70 is configured to have the same shape and dimensions in the width direction as the front end portion of the upper blade 41 in the top view of the slider 2. In this case, the rear wall 71a facing rearward of the wide width portion 71 serves as a stop portion that stops the rotation of the handle 50 by colliding with the left and right side frame portions 53 of the handle 50, and rotates in a direction in which the handle 50 falls to the shoulder opening side. It functions as a rotation restricting portion (rotation preventing portion) that prevents the rotation. That is, in the slider 2 according to the second embodiment, the range from the lying state where the handle 50 is laid down to the rear opening side of the slider body 40 to the state where the left and right frame portions of the handle 50 are in contact with the rotation restricting portion of the cover member 70. Can be rotated.

Next, a procedure for assembling the slider 2 according to the second embodiment having the above-described components will be described.
First, the attachment shaft portion 51 of the handle 50 is attached to the left and right handle holding portions 47 of the slider body 40. Specifically, the mounting shaft portion 51 of the handle 50 is inserted between the front and

rear column portions

47a and 47b of the left and right handle holding portions 47, and then the upper end portions of the front and

rear column portions

47a and 47b are brought closer to each other. To cause plastic deformation. As a result, the attachment shaft portion 51 of the handle 50 is held by the left and right handle holding portions 47 so as to be rotatable at a predetermined position.

Subsequently, as shown in FIG. 12, the stop claw body 60 serving as a pulling biasing member in the state where the pulling handle 50 in which the mounting shaft 51 is held by the pulling holding portion 47 is tilted to the rear opening side, The elastic deformation portion 64 of the stop claw body 60 is disposed so as to be accommodated in the accommodation groove 41 a from the upper side of the slider body 40.

At this time, the position of the first contact portion 62a and the second contact portion 62b of the stop claw body 60 corresponds to the positions of the first cam portion 56 and the second cam portion 57 of the handle 50, respectively. The position of 60 is aligned, and the stop claw portion 61 of the stop claw body 60 enters the element guide path through the claw hole 41c of the slider body 40. Thereafter, the left and right crimping portions 41b provided on the upper blade 41 are crimped so as to bend inward in the slider width direction. As a result, the stop claw body 60 is attached to the slider body 40 by the crimping portion 41b, and the attachment shaft portion 51 of the handle 50 is rotatably disposed between the upper surface of the upper blade 41 and the stop claw body 60. .

Next, the cover member 70 is put on the upper blade 41 of the slider body 40 to which the stop claw body 60 is attached. At this time, the left and right front fixed columns 45 and the rear fixed columns 46 disposed on the upper blade 41 are accommodated in the cover member 70, and the mounting shaft portion 51 of the handle 50 is disposed in the insertion hole 73 of the cover member 70. In this manner, the cover member 70 is placed on the upper blade 41. At the same time, the left and right front fixing columns 45 and the rear fixing columns 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 predetermined position of the upper blade 41.

After the cover member 70 is placed on the upper wing plate 41, the portion of the cover member 70 corresponding to the insertion hole portion 46a formed in the front fixed column 45 and the rear fixed column 46 is locally pressed from the outside to be recessed inside. I will. Thereby, a convex part is formed in the inner wall surface of the cover member 70, and each convex part is each fitted in the corresponding insertion hole part 46a formed in the front fixed pillar 45 and the back fixed pillar 46, respectively. As a result, the cover member 70 is fixed to each of the left and right front fixing columns 45 and the rear fixing columns 46, and thereby the slider 2 of the second embodiment is assembled.

The slider 2 of the second embodiment obtained in this way can constitute a slide fastener by inserting the element rows of the left and right fastener stringers through the element guide path of the slider 2. Further, when the slide fastener is configured, the slider 2 of the second embodiment stops the stop claw body 60 by causing the handle 50 to fall on the rear opening side of the slider body 40 as shown in FIG. The stopping mechanism can be operated by causing the claw portion 61 to enter the element guide path of the slider body 40.

On the other hand, by gripping the knob portion 52 of the handle 50 with a finger and rotating the handle 50 so as to stand up about the attachment shaft portion 51 of the handle 50, for example, as shown in FIG. The first cam portion 56 and the second cam portion 57 can also be rotated to change their directions.

At this time, the stop claw body 60 is gradually lifted against the urging force of the elastic deformation portion 64 of the stop claw body 60 by the rotating first cam portion 56, and the stop claw portion 61 is moved to the element guide path of the slider body 40. Can be removed from. Thereby, the slider 2 can be smoothly slid along the element row.

Further, as shown in FIG. 15, when the handle 50 is rotated so as to be inclined at approximately 40 ° with respect to the upper surface on the rear opening side of the upper blade 41, the first contact portion 62a of the stop pawl body 60 is The contact point of the cam portion 56 is more than the position of the contact point where the attachment shaft portion 51 of the handle 50 contacts the bottom surface of the handle holding portion 47 provided on the upper surface of the upper blade 41. It is arranged on the side (that is, the rear side).

For this reason, when the finger is released from the knob 52 of the handle 50 and the handle 50 becomes free, the urging force of the elastic deformable portion 64 of the stop claw body 60 acts on the first cam portion 56, and the first cam portion. Since a force in a downward direction or a downward slanting direction is applied to the contact point of the 56 with respect to the handle holding portion 47, the rotation of the handle 50 is urged to the rear opening side of the slider body 40, and the handle 50 is stably laid down. Can do.

Further, even in the state where the puller 50 is lying on the rear opening side of the slider body 40, the first cam part 56 is in contact with the puller holding part 47, so that the puller 50 receives the urging force from the stop claw body 60, The lying state of the puller 50 can be stably maintained.

Furthermore, in the slider 2 of the second embodiment, even if the handle 50 is rotated until the inclination angle of the handle 50 reaches a predetermined cam switching angle (for example, 60 °), the first cam portion 56 of the handle 50 is stopped by the pawl body 60. The stop pawl body 60 is lifted against the urging force of the elastic deformation portion 64. For this reason, when the finger is released from the knob portion 52 of the handle 50, the urging force by the elastic deformation portion 64 of the stop claw body 60 acts on the first cam portion 56, and the handle 50 is stably inclined to the rear mouth side. Can be made.

Further, when the handle 50 is rotated to the second rotation range where the inclination angle is equal to or greater than the cam switching angle, the first cam 56 of the handle 50 is separated from the first contact portion 62a of the stop pawl body 60, but the first cam The second cam portion 57 contacts the second contact portion 62b of the stop claw body 60 at the same time as the portion 56 moves away from the first contact portion 62a or immediately before it leaves the first contact portion 62a. Can be lifted against the urging force of the elastic deformation portion 64.

In this case, the contact point of the second cam portion 57 with respect to the second contact portion 62b is from the position of the contact point where the attachment shaft portion 51 of the handle 50 contacts the bottom surface portion of the handle holding portion 47 provided on the upper surface of the upper blade 41. Is also arranged on the side of the knob 52 of the handle 50 in the lying state (that is, the rear side).

For this reason, by releasing the finger from the knob portion 52 of the handle 50 and making the handle 50 free, the biasing force of the elastic deformation portion 64 of the stop claw body 60 acts on the second cam portion 57, and the slider body 40 The rotation of the handle 50 toward the rear opening can be promoted. Further, when the handle 50 rotates toward the rear opening side and the inclination angle of the handle 50 becomes equal to or smaller than the cam switching angle, the second cam portion 57 of the handle 50 is separated from the second contact portion 62b of the stop pawl body 60. At the same time, since the first cam portion 56 continuously contacts the first contact portion 62a of the stop claw body 60, the urging force of the elastic deformation portion 64 of the stop claw body 60 acts on the first cam portion 56 again. The puller 50 can stably fall on the rear mouth side.

Further, in the slider 2 of the second embodiment, for example, as shown in FIG. 16, the handle 50 is rotated by rotating the handle 50 so as to stand substantially 90 ° with respect to the upper surface on the rear opening side of the upper blade 41. Since the left and right frame portion 53 abuts against the rotation restricting portion (rear wall body 71a) of the cover member 70 and the rotation of the pull handle 50 is restricted, the pull handle 50 is 90 with respect to the upper surface on the rear opening side of the upper blade 41. It is possible to prevent it from rotating so as to be tilted by more than °.

In the slider 2 according to the second embodiment, when the inclination angle of the handle 50 is approximately 90 °, the finger 50 is released by releasing the finger from the knob 52 of the handle 50, whereby the elasticity of the stop nail body 60 is increased. Since the urging force of the deforming portion 64 acts on the second cam portion 57, the rotation of the handle 50 toward the rear opening side of the slider body 40 can be promoted, and the pulling handle 50 can be effectively laid down toward the rear opening side.

As described above, in the slider 2 according to the second embodiment, like the slider 2 according to the first embodiment, the first cam portion 56 and the second cam portion 57 having different protruding directions from the attachment shaft portion 51 of the handle 50. Therefore, the first cam portion 56 and the second cam portion 57 rotate in the direction in which the handle 50 falls in the first rotation range and the second rotation range in which the inclination angles of the handle 50 are different from each other. Can be effectively laid down.

Further, the first cam portion 56 and the second cam portion 57 of the handle 50 are selectively brought into contact with the cover member 70 according to the inclination angle of the handle 50 in this way, and the biasing force of the cover member 70 is increased. Therefore, even if the handle 50 is rotated to a large inclination angle, the handle 50 can be stably laid down if the finger is released from the handle 50.

In the sliders 1 and 2 of the first and second embodiments described above, when the sliders 1 and 2 are not slid, the

pullers

20 and 50 are moved by the biasing force of the puller biasing member. It is configured to automatically tilt to the rear opening side and maintain the fallen state of the pull handles 20 and 50. However, in the present invention, when the sliding operation is not performed, the slider is configured so that the pulling handle is automatically tilted to the shoulder opening side of the slider body by the biasing force of the pulling biasing member, and the falling state of the pulling is maintained. It is also possible to do.

Further, according to the first and second embodiments described above, the rotation restricting portion is provided so that the

handle

20, 50 does not rotate beyond the second rotation range, but in the present invention, the handle has the second rotation. The slider may be configured to rotate beyond the range. In this case, the handle rotates to the fall position (second fall position) in the opposite direction to the fall position (first fall position) biased by the first and second cam portions. In other words, in the present invention, the slider is rotated so that the puller can rotate in a range from the first lying position where the slider body falls to the rear side of the slider body to the second lying position where the handle body falls to the shoulder side of the slider body. It is also possible to configure.
