第一实施方式
图 1 ~图 6为表示本发明的第一实施方式的拉链用链牙的图。 图 1为本发明的第一实施方式的拉链用链牙的正视图, 图 2为本 发明的第一实施方式的拉链用链牙的俯视图, 图 3为本发明的第 一实施方式的拉链用链牙的左侧视图, 图 4为本发明的第一实施 方式的拉链用链牙的仰视图, 图 5为表示安装有本发明的第一实 施方式的链牙的链带的局部正视图, 图 6为表示安装有本发明的 第一实施方式的链牙的拉链的卡合状态的局部立体图。
如图 6所示, 拉链 A具有一对链带 2, 2, 在每一个链带 2 上,以沿着布带 21的长度方向按一定的间隔均匀排列的方式在布 带 21的缘部 22上安装有拉链用链牙 (以下称为链牙 ) 1。
如图 1 ~图 4所示, 在上下方向上, 链牙 1以布带 21为边界 包括位于布带 21的上表面侧的第一部分 11, 和位于布带 21的下 表面侧的第二部分 12。
第一部分 11具有平坦的上表面 lla, 该上表面 11a相对于布 带 21的上表面平行,并且在上下方向上与相邻的链牙 1的第一部 分 11的上表面 11a处于相同的水平面。 在没有形成下述的槽 14 时, 第一部分 11整体形成为大致四棱锥台形状,且该四棱锥台的 侧部的四条棱进行了倒角,但是并不局限于此, 第一部分 11整体 也可以形成为大致长方体、 大致立方体等形状, 其四条棱也可以 不进行倒角。
第二部分 12包括本体部 12a, 头部 12c、 颈部 12b。 本体部 12a与第一部分 11在上下方向上夹持布带 21以便将链牙 1 固定 在布带 21上。头部 12c以在与布带 21的长度方向垂直的方向上, 经由颈部 12b从本体部 12a向相向的链牙 1侧突出的方式形成, 在一对链带 2, 2相互卡合时头部 12c与相向的链牙 1的头部 12c 相互卡合。 并且, 特别需要说明的是, 在与布带 21的长度方向垂 直的方向上,头部 12c也比第一部分 11更向相向的链牙 1侧突出。 颈部 12b设置于本体部 12a与头部 12c之间, 具有呈沙漏形的中 间缩窄的形状, 从而, 在与布带 21的长度方向垂直的方向上, 颈 部 12b的宽度比本体部 12a以及头部 12c的宽度窄。 由此, 在布 带 21的长度方向上, 在相邻的链牙的第二部分 12的颈部 12b彼 此之间能够形成用于收容相向的链牙 1的第二部分 12的头部 12c 的空间。
在链牙 1的上表面 (即, 在第一部分的上表面 11a )上, 在
第一部分 11的左右方向的中央部, 沿着与布带 21的长度方向垂 直的方向以贯通第一部分 11的方式形成有一个槽 14, 该槽 14的 底部到达布带 21, 将第一部分 11 均等地分割成第一分割部 111 和第二分割部 112。
如图 5所示, 槽 14 的在布带 21 的长度方向上的宽度尺寸 W1设置成: 在从布带 21的上表面开始的相同的垂直高度 H上, 与在布带 21的长度方向上相邻的两个链牙 1之间的间隔尺寸 W 相同, 该高度 H为从布带 21的上表面开始到第一部分的上表面 为止的垂直距离范围内的任意高度。 虽然在本实施方式中, 以在 链牙 1的上表面上形成有槽 14的情形为例说明了槽 14的宽度尺 寸 W1与相邻的两个链牙之间的间隔尺寸 W的关系,但是在如下 述实施方式那样在链牙的下表面上形成槽的场合, 该槽的宽度尺 寸与相邻的两个链牙之间的间隔尺寸的关系也可适用,此时, "从 布带的表面开始的相同的垂直高度" 是指从布带的下表面开始朝 向下方的相同的垂直高度。
在从与布带 21 的长度方向垂直的方向观察时, 第一分割部 111和第二分割部 112的横截面形状分别形成为相同的等腰梯形 形状, 槽 14的横截面形状呈靠近布带 21—侧的底边比远离布带 21—侧的底边短的大致梯形形状, 但是并不局限于此, 第一分割 部 111和第二分割部 112的横截面形状也可以形成为等腰梯形以 外的其它的形状, 槽 14的横截面形状也可以形成为图 14 ( a )所 示那样的大致 V字形形状,在该大致 V字形横截面中,槽的开口 a的宽度随着远离布带而逐渐变大,槽 14的横截面形状还可以形 成为图 14 ( b )所示那样的大致矩形或靠近布带一侧的底边比远 离布带一侧的底边长的大致梯形等其它形状。
在本实施方式中,通过设定头部 12c从第二部分 12的本体部 12a突出的位置, 例如使头部 12c从第二部分 12的本体部 12a的
左右方向中央部突出, 如图 6所示, 在一对链带 2, 2卡合时, 能 够使第一分割部 111与相向的链牙 1中的第一分割部 111对齐, 使第二分割部 112与相向的链牙中的第二分割部 112对齐, 即, 能够使第一分割部 111与相向的链牙 1中的第一分割部 111,以及 第二分割部 112与相向的链牙中的第二分割部 112分别处在一条 直线上。 但是并不局限于此, 也可以通过设定头部 12c从第二部 分 12的本体部 12a突出的位置, 例如使头部 12c从第二部分 12 的本体部 12a的偏离左右方向中央部的位置突出,在一对链带 2, 2卡合时,使第一分割部 111与相向的链牙 1中的第二分割部 112 对齐,使第二分割部 112与相向的链牙中的第一分割部 111对齐, 即, 使第一分割部 111与相向的链牙 1 中的第二分割部 112, 以 及第二分割部 112与相向的链牙中的第一分割部 111分别处在一 条直线上。
在本实施方式中, 虽然在第一部分上仅形成有一个槽 14, 但 是如下述第五实施方式那样, 也可以在第一部分上形成两个以上 的槽。
另外, 在本实施方式中, 虽然限定了槽 14 的宽度尺寸 W1 与相邻的两个链牙 1之间的间隔 W的关系,但是也可以不遵循该 关系而将槽 14的宽度形成为其它尺寸。
