Japanese Patent Laid-Open No. 2007-075196

  In the slider operation of the slider described in Patent Document 1, when the handle 37 of the handle 8 is picked and pulled upward, the pivot 36 slides along the guide guide 18 and the cover 7 is engaged with the rear. The part 33 is lifted up to the upper limit of movement of the guide part 19 of the rear cover mounting column 11, and at the same time, the stop pawl 30 protruding from the claw hole 22 is retracted and retracted from the guide groove 6 to slide the slider. . After that, when the handle 8 is released, the stop pawl 30 is automatically lowered by the spring force of the elastic piece 31. At this time, the rear engaged portion 33 and the guide portion 19 of the rear cover mounting column 11 come into contact with each other. There is. In this case, the stop pawl 30 does not descend unless the elastic piece 31 has a spring force larger than the frictional force of the rear engaged portion 33 and the guide portion 19 of the rear cover mounting column 11. In addition, when the handle 8 is lifted, if the frictional force between the rear engaged portion 33 and the guide portion 19 of the rear cover mounting column 11 is large, the operational feeling of the puller 8 by the user is deteriorated.

It is a perspective view which shows the state by which it was carried out (however, a handle is not shown). 4A is a partial cross-sectional view taken along line AA ′ in FIG. 4B (the cross-sectional view of only the slider body, the lower blade is not shown), and FIG. 4B is the slider according to the first embodiment of the present invention. A front view and (c) show the BB 'line partial sectional view in (a) (the lower wing board is not shown), respectively. FIG. 5 shows a state in which the stop claw has been retracted by lifting the handle, with respect to the A-A ′ line partial cross-sectional view of FIG.

  The slider for slide fastener according to the first embodiment includes a slider body 130, a cover 120, a spring member 140, and a handle 110. The slider body 130 and the handle 110 can be manufactured by die casting using a metal material such as a copper alloy, an aluminum alloy, or a zinc alloy. The cover 120 and the spring member 140 can be manufactured by press molding using a metal material such as stainless steel or copper alloy.

  The slider body 130 includes an upper wing plate 132 and a lower wing plate 134 whose front end sides are connected by a connecting column 144, and a Y-shaped element guide path 137 disposed between the upper wing plate 132 and the lower wing plate 134. Have Upper flange portions 132 a are formed on the left and right side portions of the upper wing plate 132 toward the lower wing plate 134, and lower flange portions 134 a are formed on the left and right side portions of the lower wing plate 134 toward the upper wing plate 132. Has been.

  The slider body 130 has a front end of the slider body 130, a shoulder opening 156 disposed on both the left and right sides of the connecting column 144, and a rear opening 158 disposed on the rear end of the slider body 130. A Y-shaped element guide path 137 that connects the left and right shoulder openings 156 and the rear opening 158 is formed between the upper and lower blades 132 and 134.

  The upper wing plate 132 is formed between a front cover mounting column 136 erected on the front side, a rear cover mounting column 138 erected on the rear side, and the front cover mounting column 136 and the rear cover mounting column 138. A claw hole 135 and a restricting portion 139 projecting between the claw hole 135 and the front cover mounting column 136 are provided. The front cover mounting column 136 includes a support portion 136a having a trapezoidal shape and an engaging portion 136b that is supported by the support portion 136a and extends in the left-right direction. The lower surface of the engaging portion 136b protrudes from the front cover mounting column 136 to the extent that it can come into contact with the upper surface of a shaft support portion 124 of the cover 120 described later. The rear cover mounting column 138 includes a columnar support portion 138b and a stop portion 138a that is supported by the support portion 138b and protrudes left and right. The lower surface of the stop portion 138a can come into contact with the upper surface of the engagement piece 121 in order to limit the upward movement of the cover 120, which will be described later, and the front cover mounting column 136 so that the cover 120 does not come off the slider body 130. Overhangs.

  A handle guide portion 153 is formed in front of the rear cover mounting column 138. The pull guide portion 153 includes a pull guide surface that can come into contact with the rotary shaft 112 of the pull handle. The pull guide surface is a slope that descends as it goes forward, and guides the moving direction of the rotary shaft 112 of the pull handle 110. . Thereby, when the handle 110 is operated to the rear side, the rotation shaft 112 of the handle moves along the inclined surface of the handle guide surface. At this time, the handle 110 pushes up the cover body 120 along with the movement, so that the stop claw 128 of the cover body 120 can be pulled up from the claw hole 135, so that the lock can be easily released.

The upper blade 132 can have a groove 131, and the spring member 140 can be laid in the groove 131. Specifically, the groove 131 is formed in a substantially U-shape across the rear side and the left and right sides of the base of the front cover mounting column 138.
Thereby, the spring member 140 can be stably fixed on the upper blade 132, and the spring member 140 is not conspicuous from the outside. In addition, foreign matter such as cloth is less likely to be caught from the outside. Further, in the groove portion 131, the front end side of the groove on the left and right side surfaces of the front cover mounting column 136 is opened to the front end side of the upper blade 132, and the bottom surface of the groove is directed downward toward the front end. It is preferable to have a slope 146 that slopes. By providing such an inclination in the groove 131, a space between the engaging portion 136b of the front cover mounting column 136 and the groove 131 is widened when the slider is assembled. It becomes easy to insert between them, and the assembling property of the slider is improved. For the same reason, it is preferable that the upper surface of each shaft support portion 124 has a slope 148 that slopes downward toward the front end thereof.

  The cover 120 extends downward from at least one of the upper wall 125, the left and right side walls 122 extending from both side edges of the upper wall 125, and the left and right side walls 122 (only one in the first embodiment), and is inserted into and removed from the claw hole 135. Stop pawls 128, a pair of pivots 124 extending forward from the left and right side walls 122 and engaging the front cover mounting columns 136, and extending rearward from the left and right side walls 122 and loosely fitted to the rear cover mounting columns 138. A pair of engaging pieces 121, an opening 127 through which the rotation shaft 112 of the handle 110 passes through the left and right side walls 122, and a stop wall 126 capable of contacting the front portion of the restricting portion 139. Although there is no restriction | limiting in particular in the shape of the opening part 127, in order to enable smooth operation of the handle 110, it is desirable to form with the curve and the lower part of the opening part 127 is open | released. The place where the stop wall 126 is installed is not particularly limited as long as the cover 120 can be brought into contact with the restricting portion 139 when the cover 120 is moved rearward, and can be provided independently of the opening 127. It is convenient to provide it on the peripheral wall. For example, as shown in FIGS. 2 to 4, there is a method in which a wall is formed at the front end portion of the opening 127 whose lower portion is opened and this is used as the stop wall 126.

  The cover 120 is preferably provided with a protrusion 123 capable of abutting against a rear portion of the front cover mounting column 136 (in the first embodiment, a rear portion of the support portion 136a) on at least one of the left and right side walls 122, preferably from the inside in terms of stability. Can have. An example of a specific shape of the protrusion 123 is easy to understand when viewed from FIG. 4C, but it is manufactured by punching with a cylindrical press die from the outside of the left and right side walls 122 to the inside. As a result, the forward movement of the cover 120 stops when the projection 123 abuts against the front cover mounting column 136, so that the shaft support portion 124 of the cover 120 excessively bites into the engaging portion 136 b of the front cover mounting column 136. This prevents the cover 120 from rotating smoothly.

  The spring member 140 is disposed between the lower surface of the pair of shaft support portions 124 and the upper wing plate 132, and includes a base portion 141 installed between the rear end of the front cover mounting column 136 and the restriction portion 128, and the base portion 141. A pair of elastic portions 143 extending along the left and right side walls of the front cover mounting column 136 are configured so that the stop claw 128 is urged toward the claw hole 135 by the elastic portion 143. In the first embodiment, since the base shape of the front cover mounting column 136 is rectangular, the spring member 140 is a U-shaped leaf spring. The left and right plate pieces respectively extending forward from the two corners of the U-shape, that is, the elastic portion 143 has a slope that rises toward the front.

  Further, the spring member 140 may have an insertion hole 142 in the base portion 141, and after the fixing column 133 erected in the groove 131 on the rear side of the front cover mounting column 136 is inserted into the insertion hole 142, the fixing column 133 is then inserted. Can be fixed to the upper wing plate 132 by crushing. In the first embodiment, the insertion holes 142 are formed symmetrically at the corners at both ends of the base portion, and a spring force that is equal to the left and right can be transmitted to each shaft support portion 124.

  One end of the handle 110 is rotatably held by the slider body 130 by inserting the rotation shaft 112 of the handle 110 into the opening 127 of the cover 120.

  Please refer to FIG. Here, the spring member 140 is in elastic contact with the lower surface of the shaft support portion 124, and the cover 120 rotates about the contact portion between the upper surface of the shaft support portion 124 and the lower surface of the engaging portion 136b by the spring force, and the stop pawl 128 is moved. The state where it is inserted into the claw hole 135 and protrudes from the lower surface of the upper blade 132 is shown. When the protruding stop pawl 128 is inserted between the elements, the sliding of the slider 100 with respect to the element row stops. Referring to FIG. 5, the stop claw 128 is retracted from the lower surface of the upper wing plate 132 when the user lifts the rotary shaft 112 of the handle and reversely rotates the cover 120 against the action of the spring member 140. Indicates the state. In this state, it is possible to slide the slider forward or backward along the element row.

  In the slider according to the first embodiment, when the cover 120 is moved rearward, the stop wall 126 is restricted by the restricting portion before the rearward movement of the cover 120 is restricted by contact with the rear cover mounting column 138 or the claw hole 135. 139 abuts. In other words, when the stop wall 126 is in contact with the restricting portion 139, there is a rear clearance between the rear cover mounting column 138 and the cover and between the stop claw 128 and the claw hole 135. Therefore, the rearward movement of the cover 120 stops when the stop wall 126 comes into contact with the restricting portion 139.

  Accordingly, when the stop claw 128 is inserted into and removed from the claw hole 135, the cover 120 performs a rotation operation with the contact portion between the shaft support portion 124 and the engagement portion 136b as an axis. At this time, the stop wall 126 is moved to the restriction portion 139. Even if the frictional force resulting from the contact is generated, the distance from the rotating shaft to the restricting portion 139 is short, and therefore the frictional force can be suppressed to a small value.

  The position of the restricting portion 139 is not particularly limited as long as it protrudes between the claw hole 135 and the front cover mounting column 136, but from the viewpoint that the stop wall 126 keeps the frictional force between the restricting portions 139 small. The restricting portion 139 is preferably installed at a position close to the rotation axis. In the first embodiment, the restricting portion 139 is projected on the upper blade by extending the rear end wall of the groove 131 upward. Further, from the viewpoint of stability, the restricting portion 139 is preferably formed on the left and right sides so as to be able to contact the left and right stop walls 126. In the first embodiment, the restricting portion 139 forms a convex line by the convex portion being continuous in the left-right direction. Further, a protruding portion 129 that protrudes slightly further downward from the lower end portions of the left and right side walls 122 is formed so that the wall surface that contacts the restricting portion 139 of the opening 127 on the cover 120 side can stably contact the restricting portion 139. ing.

  Next, the slider assembling operation according to the first embodiment will be described. A spring member 140 is laid in the groove 131 of the upper blade 132 of the slider body 130. At this time, the fixing pillar 133 is inserted into the insertion hole 142 of the spring member 140. By crushing the portion protruding from the insertion hole 142 of the fixed column 133, the fixed column 133 is crushed in the head as shown in FIGS. 140 is fixed to the upper blade 132. Next, the shaft support portion 124 of the cover 120 is fitted into the space between the engagement portion 136 b of the front cover mounting column 136 and the groove portion 131 with the rotation shaft 112 of the handle being inserted through the opening portion 127. At substantially the same time, the stop claw 128 is inserted into the claw hole 135. Since the distance between the pair of engagement pieces 121 of the cover 120 is larger than the left and right widths of the stop portions 138a of the rear cover mounting column 138, the engagement pieces 121 do not interfere with the stop portions 138a. 121 can be mounted on the upper blade 132. Thereafter, each engagement piece 121 is bent inward so that the distance between the engagement pieces 121 is shorter than the left and right widths of the stop portion 138a, so that the vertical movement of each engagement piece 121 is 132 and the stop 138a. Along with this, the movement distance of the stop claw 128 in the vertical direction is also determined. The distance between the upper blade 132 and the stopping portion 138a should be a sufficient distance to control the sliding and stopping of the slider by the vertical movement of the stop pawl 128. If each engagement piece 121 is bent too much inward, each engagement piece 121 comes into contact with the support portion 138b and generates a frictional force that hinders the rotational movement of the cover 120. It is preferable to bend so as not to contact the portion 138b or to keep it to a minimum even if it contacts.

<Example 2>
FIG. 6 is a perspective view showing a state in which parts constituting the slide fastener slider according to the second embodiment of the present invention are separated. The slider according to the second embodiment has a form similar to the slider according to Japanese Patent Laid-Open No. 2007-075196 (Patent Document 1) described in FIG. While the portion 139 does not exist, the second embodiment is greatly different in that the restricting portion 139 exists.

  Similar to the first embodiment, the slide fastener slider according to the second embodiment includes a slider body 130, a cover 120, a spring member 140, and a handle 110. Since there are many common points between the first embodiment and the second embodiment, the following description will focus on the differences from the first embodiment.

  First, the shape of the cover 120 is different. In the second embodiment, the spring member 140 is continuous with the cover 120 by extending in front of the cover 120. Specifically, the spring member 140 has a long plate shape that extends forward from the front end portion of the upper wall 125 of the cover 120, moves forward a certain distance, then bends downward and hangs down a certain distance. The distal end portion of the spring member 140 is in elastic contact with a spring member guide portion 154 described later. Then, a rotational force about the contact portion between the shaft support portion 124 and the engaging portion 136 b is generated in the cover 120 by the spring force, and the stop claw 128 is urged toward the claw hole 135.

  Further, in the second embodiment, the stop claw 128 has a portion that bends forward, and the tip of the stop claw 128 approaches the front of the slider. As a result, the stop pawl 128 can be inserted into a portion having a relatively large gap immediately before the left and right elements mesh with each other, so that it is possible to prevent the fastener stringer sewing thread from being damaged. Accordingly, the claw hole 135 is formed to be longer forward than the first embodiment.

  In the second embodiment, the pair of engagement pieces 121 extend rearward linearly and are not bent inward.

  Secondly, the shape of the front cover mounting column 136 standing on the upper blade 132 is different. In the second embodiment, a spring member guide portion 154 having a slope inclined downward is formed in the front portion of the support portion 136a. The left and right engaging portions 136b are connected to the upper wing plate 132 at the lower portion while the inner portion is supported by the support portion 136a.

  Third, the shape of the rear cover mounting column 138 erected on the upper blade 132 is different. In the second embodiment, convex-shaped guide portions 152 are vertically extended on the left and right side surfaces of the support portion 138b. Thereby, swinging of the cover 120 in the left-right direction can be suppressed. However, the width of the guide portion 152 in the left-right direction suppresses the cover 120 from becoming difficult to rotate due to the frictional force, and the automatic stop function is smoothly exhibited. It is desirable that the width is such that it does not contact or is minimal even if it contacts.

  Fourthly, since the upper blade 132 has no groove 131, the restriction portion 139 is formed independently. However, in the second embodiment as well, the movement of the cover 120 to the rear is restricted by the restricting portion 139. Therefore, when the stop claw 128 is inserted into and removed from the claw hole 135, the cover 120 is connected to the shaft support portion 124 and the engaging portion 136b. When a rotation operation is performed with the contact portion as an axis, even if a frictional force is generated due to the stop wall 126 coming into contact with the restricting portion 139, the distance from the rotating shaft to the restricting portion 139 is short. The frictional force can be kept small.

As described above, the embodiments of the present invention have been described with reference to the drawings with reference to examples. However, there are many other modifications of the present invention. For example, a coil spring can be used as the spring member 140. Specifically, the spring member 140 can be housed in a housing hole provided in the vertical direction on the upper wall of the front cover mounting column 136. The upper end of the spring member 140 is brought into elastic contact with the inside of the front end portion of the upper wall 125 of the cover 120, and the front end portion of the upper wall 125 of the cover 120 is pushed up from the inside by the spring force. As a result, unless the user applies a force to resist this, a force that rotates the cover 120 around the contact portion between the shaft support portion 124 and the engagement portion 136b works, and the stop claw 128 is automatically inserted into the claw hole 135. Thus, the upper blade 132 protrudes from the lower surface.
