Detailed Description
Hereinafter, a slider for a slide fastener according to each embodiment of the present invention will be described in detail with reference to the drawings.
In the present embodiment, the front-rear direction of the slider is a direction parallel to the sliding direction of the slider, and in the slide fastener, the direction in which the slider slides when the left and right elements are engaged is defined as the front, and the direction in which the slider slides when the left and right elements are disengaged is defined as the rear. The left-right direction of the slider is a direction parallel to the fastener tape surface when the slide fastener is configured and perpendicular to the front-rear direction of the slider, and the up-down direction of the slider is the same direction as the front-back direction of the fastener tape when the slide fastener is configured.
(embodiment 1)
As shown in fig. 1 and 2, a slider 10 for a slide fastener according to embodiment 1 includes: a slider body 20 which is formed by die casting and through which fastener elements of a pair of right and left fastener tapes are inserted; an elastic body 50 formed by a plate spring; a pull tab 60 provided to the slider body 20 so as to be rotatable; and a cover 70 that holds the pull tab 60 to the slider body 20. The slider 10 of the present embodiment is made of metal and is a free slider having no pawl that bites into the fastener element row.
Referring also to fig. 3 (a) and 3 (b), the slider body 20 includes: an upper wing plate 21 and a lower wing plate 22 which are disposed in parallel in the vertical direction and face each other; a guide column 23 having an upper blade 21 and a lower blade 22 connected to the front end thereof; a recess 24 provided along the front-rear direction on the upper surface 21a of the upper blade 21; cover attachment portions 26, 27 protruding upward from the outside of the recess 24 on the upper surface 21a of the upper blade 21; and a flange 25 extending from both side edges of the upper wing 21 and the lower wing 22 in a direction to approach each other, for guiding the fastener element.
The flange 25 may be provided only on one of the upper wing 21 and the lower wing 22 depending on the form of the fastener element.
Further, left and right shoulder openings 20a separated by the guide posts 23 are formed at the front of the slider body 20, and a rear opening 20b is formed at the rear of the slider body 20. A Y-shaped element insertion path 20c (see fig. 3 (b)) is provided between the upper wing plate 21 and the lower wing plate 22, the element insertion path 20c communicating with the left and right shoulder openings 20a and the rear opening 20b, and the element insertion path 20c is a path through which the left and right fastener elements are inserted when the slide fastener is constructed.
A flat elastic body 50 is housed in the recess 24 formed in the upper surface 21a of the upper panel 21 so that the longitudinal direction thereof extends along the front-rear direction of the recess 24. The recess 24 has a rectangular shape having a size substantially equal to the length and width of the elastic body 50 in a plan view, and is recessed from the upper surface 21 a. Specifically, the concave portions 24 constitute mounting surfaces on which the front and rear end mounting elastic bodies 50 are mounted, and are arc-shaped curved surfaces that gradually become deeper from the front and rear ends toward the center.
The pair of cover attachment portions 26, 27 are located forward or rearward of the recess 24 and are provided to protrude upward from the upper surface 21a of the upper panel 21. The cover attachment portions 26, 27 have protruding portions 28 protruding in the left-right direction from portions near the recess 24 at the front end portion or the rear end portion. Further, a hook portion 29 is formed above a portion closer to the recess 24 than the protruding portion 28, and a receiving portion 30 is formed below the portion, and the receiving portion 30 is recessed in the right-left direction with respect to the hook portion 29. The housing portions 30 of the cover attachment portions 26 and 27 respectively house and engage a front engagement portion 74 or a rear engagement portion 75, which will be described later, formed in the cover 70, and cover the upper side, front side, or rear side of the front engagement portion 74 or the rear engagement portion 75 with the hook portions 29 and the projecting portions 28, thereby holding the cover 70 in a stable state.
The hook portion 29 is formed so that the lateral side surface thereof in the left-right direction has a width that gradually increases downward, and is formed so that the front engaging portion 74 or the rear engaging portion 75 of the cover 70 can be smoothly guided to the accommodating portion 30 when the cover 70 is engaged with the cover attachment portions 26 and 27.
As shown in fig. 2, the pull tab 60 includes: a shaft 61 extending in the left-right direction, located above the elastic body 50, and rotatably supported by the slider body 20; a tab body 62 extending from the shaft 61 to the outside in the radial direction of the shaft 61; and a cam 63 protruding from the shaft 61 outward in the radial direction of the shaft 61. At least a portion of the cam 63 is located above the elastic body 50. The pull-tab 60 further includes left and right arms 64, and the left and right arms 64 connect between both ends of the shaft 61 and the pull-tab body 62, and together with the shaft 61 and the pull-tab body 62, form window portions 65 into which the cover attachment portions 26, 27 can be inserted.
The cam 63 has a convex portion 63a (see fig. 4) that protrudes outward in the radial direction at a predetermined position, and elastically deforms the elastic body 50 in the concave portion 24 in accordance with the position of rotation of the tab 60.
Therefore, in assembling the slider 10, the elastic body 50 is first placed in the recess 24 of the slider body 20, and the shaft 61 of the pull tab 60 is further placed above the elastic body 50. Then, the cover 70 is moved from above toward the upper blade 21 of the slider body 20 so that the opening 73 of the cover 70 surrounds the shaft 61, whereby the front engaging portion 74 and the rear engaging portion 75 of the cover 70 are engaged with the receiving portion 30, and the 4 members are integrated.
As shown in fig. 5 (a) to 7 (c), the slider 10 thus assembled enables the pull tab 60 to be turned as follows: the tab 60 is rotated from a position where it falls by approximately 90 ° forward (one side in the front-rear direction) where one surface of the tab 60 abuts the upper surface 21a of the upper flap to a position where it falls by approximately 90 ° rearward (the other side in the front-rear direction) where the other surface of the tab 60 abuts the upper surface 21a of the upper flap. The tab body 62 is substantially horizontal to the upper surface 21a of the upper paddle 21 at any one of a position where the tab 60 is folded forward by substantially 90 ° and a position where the tab is folded backward by substantially 90 °.
As shown in fig. 5 (a) and 5 (b), when the tab body 62 is substantially horizontal to the upper surface 21a of the upper paddle 21 and the tab 60 is tilted backward by substantially 90 °, the convex portion 63a of the cam 63 elastically deforms the elastic body 50 in a state where the cover 70 is in contact with the shaft 61. Further, since the distal end 63a1 of the convex portion 63a of the cam 63 elastically deforms the elastic body 50 at a position forward of the rotation center O of the shaft 61, a force for rotating the pull tab 60 in the counterclockwise direction acts on the pull tab 60 in fig. 5 (a) and 5 (b), and therefore the arm portion 64 of the pull tab 60 abuts against the upper surface 21a of the upper blade 21, and the pull tab 60 is fixed to the slider body 20 (i.e., the posture is maintained without shaking).
As shown in fig. 6 (a) and 6 (b), the convex portion 63a of the cam 63 elastically deforms the elastic body 50 even when tilted backward by approximately 45 °. In this case, the elastic body 50 is elastically deformed at the position rearward of the rotation center O of the shaft 61 by the tip end 63a1 of the convex portion 63a of the cam 63, and therefore, a force for rotating the tab 60 in the clockwise direction (forward) acts on the tab. From this state, as the tab 60 rotates forward, the amount of elastic deformation of the elastic body 50 by the cam 63 decreases, and in a state where the tab 60 is positioned directly above as shown in fig. 7 (a), the cam 63 is in a state where the elastic body 50 cannot be elastically deformed. In addition, in a state where the tab 60 is tilted forward by approximately 45 ° as shown in fig. 7 (b) and in a state where the tab 60 is tilted forward by approximately 90 ° as shown in fig. 7 (c), the cam 63 allows the rotation without elastically deforming the elastic body 50.
The slider 10 configured as described above may be assembled as described above after the plating treatment is performed on each of the slider body 20 and the pull tab 60, and thus, it is possible to obtain a better appearance than a conventional slider that requires the plating treatment after the assembly.
(embodiment 2)
Next, a slider according to embodiment 2 of the present invention will be described with reference to fig. 8 to 14 (b). The slider 10A of the present embodiment is different from the configuration of embodiment 1 in the shape of the upper surface 21a of the upper blade 21 of the slider body 20A, the shape of the cam 63 of the pull tab 60A, and the shape of the cover 70A.
That is, in the slider body 20A of the present embodiment, the cover attachment portion 33 is formed to have a front wall 33a, a rear wall 33b, and a pair of side walls 33c so as to surround the front and rear, and the left and right of the recess 24. The pair of side walls 33c have openings 34 that open upward and into which the shafts 61 of the tabs 60A are inserted, and the openings 34 regulate the front-rear direction positions of the shafts 61.
The front wall 33a and the rear wall 33b of the cover attachment portion 33 are provided with a front engaged portion 35 and a rear engaged portion 36, which are formed by cutting out a part of the upper surface 21a of the upper blade 21 and are recessed toward the recess 24 in the front-rear direction.
Unlike embodiment 1, the recess 24 of the present embodiment is formed above the upper surface 21a of the upper blade 21.
The cover 70A includes: an upper surface portion 71 that covers the upper side of the opening portion 34 of the cover attachment portion 33 and extends in the front-rear direction; and a front surface portion 76 and a rear surface portion 77 formed by bending downward in front of and behind the upper surface portion 71. The front surface portion 76 and the rear surface portion 77 have a front engaging portion 74 and a rear engaging portion 75 on their inner surfaces facing each other, and the front engaging portion 74 and the rear engaging portion 75 are engaged with the front engaged portion 35 and the rear engaged portion 36 of the cover mounting portion 33, respectively.
As shown in fig. 10 (b), projecting pieces 78 are provided at two locations in the front-rear direction of the upper surface portion 71 so as to be separated from each other, and the projecting pieces 78 project downward with a lateral dimension substantially equal to the inner surfaces of the pair of side walls 33c. Therefore, when the cover 70A is attached to the cover attachment portion 33, the 2 projecting pieces 78 are brought into contact with or closely face each other by the inner surfaces of the pair of side walls 33c, whereby the cover 70A is positioned in the left-right direction with respect to the slider body 20A.
As shown in fig. 11, the cam 63 of the tab 60A is provided with a flat surface 63b on the side opposite to the convex portion 63 a.
In assembling the slider 10A of the present embodiment, first, the elastic body 50 is also placed in the recess 24 of the slider body 20A, and the shaft 61 of the pull tab 60A is placed above the elastic body 50 so as to fit into the opening 34 of the cover attachment portion 33. Then, by moving the cover 70A from above the elastic body 50 and the shaft 61 toward the upper blade 21 of the slider body 20A, the front engaging portion 74 and the rear engaging portion 75 of the cover 70A are engaged with the front engaged portion 35 and the rear engaged portion 36 of the cover mounting portion 33, and 4 components are integrated.
As shown in fig. 12 (a) to 14 (b), in the slider 10A assembled in this way, the pull tab 60A can also be turned as follows: the tab 60A is rotated from a position in which the tab body 62 of the tab 60A is laid down at substantially 90 ° forward of the upper surface 21a of the upper flap in a substantially horizontal state to a position in which the tab body 62 of the tab 60A is laid down at substantially 90 ° rearward of the upper surface 21a of the upper flap in a substantially horizontal state. The tab 60A is fixed to the slider body 20A at any one of a position where the tab 60A is folded forward by substantially 90 ° and a position where the tab 60A is folded backward by substantially 90 °.
That is, as shown in fig. 12 (a) and 12 (b), when the tab 60A is tilted backward by substantially 90 ° and the tab body 62 is substantially horizontal to the upper surface 21a of the upper blade 21, the convex portion 63a of the cam 63 comes into contact with the elastic body 50 and is elastically deformed in a state where the upper surface portion 71 of the cover 70A comes into contact with the flat portion 63b of the cam 63, and the tab 60A is fixed to the slider body 20A.
Further, as shown in fig. 14 (b), when the tab 60A is tilted forward by substantially 90 ° and the tab body 62 is substantially horizontal to the upper surface 21a of the upper blade 21, the flat surface 63b of the cam 63 comes into contact with the elastic body 50 and is elastically deformed in a state where the upper surface 71 of the cover 70A comes into contact with the convex portion 63a of the cam 63, and the tab 60A is fixed to the slider body 20A.
As shown in fig. 13 (a), 13 (b), and 14 (a), when the tab 60A is tilted backward by approximately 45 °, positioned right above, and tilted forward by approximately 45 °, the convex portion 63a, the flat surface portion 63b, and the other peripheral surfaces of the cam 63 are in contact with the elastic body 50, and the elastic body 50 is elastically deformed, thereby preventing the tab 60A from shaking.
The slider 10A configured as described above may be assembled as described above after the plating treatment is performed on each of the slider body 20A and the pull tab 60A, and thus, a better appearance can be obtained than in the conventional slider that requires the plating treatment after the assembly.
Other structures and operations are the same as those of embodiment 1.
The present invention is not limited to the above embodiment, and modifications, improvements, and the like can be appropriately made.
For example, in embodiment 2, the pull tab 60A is fixed to the slider body 20A at positions which are tilted forward by substantially 90 ° and backward by substantially 90 ° by abutment of the flat surface portion 63b of the cam 63 against the upper surface portion 71 of the cover 70A or the elastic body 50, but the pull tab 60A may be fixed to the slider body 20A at least one of positions which are tilted forward by substantially 90 ° and backward by abutment of the arm portion 64 of the pull tab 60A against the upper surface 21a of the upper blade 21 by changing the shape or the like of the cam 63 as in embodiment 1.
