图 1-11显示了根据本发明第一实施例的杠杆夹机构 100。根据本 发明第一实施例的杠杆夹机构 100包括大体上扁平的基板 101。在基 板 101 的一个纵向侧部固定地安装两个相互间隔开并平行的环部 103， 两个环部 103从基板 101大体上垂直地向上延伸， 并且在其自 由端略微地弯曲以形成弯曲部。 在基板 101 的另一纵向侧部可动地 安装有环部件 105。 环部件 105 包括两个相互间隔开并平行的环部 105a, 以及将两个环部 105a连接成一体的连接部 105b。 每个环部 105a 分别在其自由端形成有弯曲部， 以使环部件 105 的两个环部 105a可与固定地安装到基板 101上的对应相对环部 103相互配合形 成闭合环。 环部件 105的两个环部 105a在其接近基板的另一端通过 连接部 105b—体地相互连接。 连接部 105b在其中部大体上水平地 向着基板中心弯曲形成大体上 U形的弯曲部 105c， 弯曲部 105c中 间部分略微向上突起形成突起部 105d，在弯曲部 105c上突起部 105d
9 P2007441M 的两侧形成有凹部 105e。 环部 103和环部件 105分别具有大体上圆 形或椭圆形横截面， 并且由诸如钢丝或类似的合适材料制成。 通过 在基板安装环部件 105 —侧两端切割或冲压、 并将被切割或冲压的 基板部分向上和向外翻卷形成的两个翻卷部 107，将环部件 105可动 地安装到基板 101上。
在基板安装环部件 105 的纵向侧部附近通过切割或冲压并且将 被切割或冲压的基板部分大体上直立地从基板向上弯折， 从而在基 板 101 中心部形成大体上直立的凸起部 109。 由于向上弯折凸起部 109而在基板 101上形成切口 111 (见图 1和 4 )。在基板安装环部件 105的纵向侧部边缘附近还形成有细长槽 113， 细长槽 113的作用以 下将描述。还可以在基板上形成一个或者多个孔 115， 用于将杠杆夹 机构固定到文件夹或者笔记本等的封皮上。
根据本发明的杠杆夹机构 100还包括杠杆 117。 杠杆 117包括杠 杆本体 117a、 从杠杆本体 117a—端倾斜向上延伸的杠杆头部 117b、 以及从杠杆本体 117a向另一端延伸的杠杆手柄部 （操作端） 117c。 根据本发明的杠杆夹机构 100还包括辊子 119。辊子 119优选地由塑 料制成。 辊子 119通过销轴 121被安装到杠杆本体 117a与杠杆头部 117b的接合部。
在组装的杠杆夹机构 100中， 两个环部 103通过诸如铆接、焊接 或者其它公知连接方式固定地安装在基板 101 —个纵向侧部。 环部 件 105通过两个翻卷部 107可动地固定环部件 105的连接部 105b的 两端， 并且使每个连接部 105b的 U形弯曲部 105c的中间部分大体
10 P2007441M 上位于凸起部 109附近， 从而将环部件 105可动地安装到基板 101 另一纵向侧部上， 使得环部件 105的两个环部 105a分别与固定地安 装的两个环部 103相互对齐。 装有辊子 119的杠杆 117在杠杆头部 117b 的自由端通过诸如铆钉的固定件 123 可转动地安装到凸起部 109上，使得辊子 119大体上可在环部件 105的弯曲部 105c上移动。 大体上略微成弓形弯曲的弹簧片 125—端被插入到基板 101上的细 长槽 113中而保持在基板 101上， 其另一端被置于环部件 105的弯 曲部 105c下方并弹性地抵靠环部件 105的弯曲部 105c，用于通过弹 力向上推动环部件 105的弯曲部 105c。 当然， 弹簧片 125的安装位 置也不局限于所示位置， 只要弹簧片 125能够抵靠弯曲部 105c下侧 即可。 此外， 弹簧片 〗25 的形状也不局限于所示形状， 只要弹簧片 125能够抵靠弯曲部 105c下侧产生向上推力即可。
如图 5所示， 杠杆夹机构处于打开状态下， 此时， 通过握住杠杆 手柄部 117c朝向基板转动杠杆 117，可以使杠杆头部 117b绕着固定 件 123从图 5所示状态顺时针转动， 导致安装到杠杆本体 117a与杠 杆头部 117b的接合部处的辊子 119在环部件 105的弯曲部 105c上 沿着远离杠杆手柄部 1 17c的方向移动到突起部 105d (即， 辊子 119 从凹部 105e移动到突起部 105d)， 克服弹簧片 125的向上推力而将 连接部 105b压靠到基板 101 上， 从而带动环部件 105 的两个环部 105a—起移动到与两个相对环部 103相接触的位置， 形成如图 2所 示的闭合环以保持活页纸。
与此相反， 在图 2所示的杠杆夹机构闭合状态下， 通过握住杠杆
11 P2007441M 手柄部 117c向上远离基板转动杠杆 117，可以使杠杆头部 117b绕着 固定件 123从图 2所示状态逆时针转动， 导致安装到杠杆本体 117a 与杠杆头部 117b 的接合部处的辊子 119沿着朝向杠杆手柄部 117c 的方向移离突起部 105d (即， 辊子 119从突起部 105d移动到凹部 105e ) , 而松开对连接部 105b的压靠， 从而使连接部 105b在弹簧片 125 的向上推力作用下移离基板 101， 带动环部件 105 的两个环部 105a移离固定地安装的两个相对环部 103， 形成打开环以打开杠杆 夹机构， 以便存取活页纸。
相对于现有的杠杆夹机构， 由于在弯曲部 105c 上设置了凹部 105e, 因此从打开位置到闭合位置， 杠杆手柄部 117c的翻转角度明 显比现有的杠杆夹机构小， 使得杠杆手柄部 117c不会与夹内的纸张 造成干涉。 优选地， 在本发明中， 所述凹部 105e的深度被设置成使 得突出部 105d的最高点与凹部 105e的最低点之间的距离大于或等 于制成环部件的钢丝的直径 D (如图 9B和 9C所示）。另外，优选地， 在本发明中， 所述凹部 105e的深度被设置成使得突出部 105d的最 高点与凹部 105e的最低点之间的距离大于或等于 4.5mm。
为了确保合适地闭合和打开杠杆夹机构，优选地，在突起部 105d 的中部具有凹陷 105f以便于在闭合杠杆夹机构时定位所述辊子 119。
优选地， 在凸起部 109上、面向环部件的一侧上形成两个阻挡部 127a和 127b， 分别用于限制闭合杠杆夹机构时杠杆头部 117b能够 旋转的范围、以及打开杠杆夹机构时杠杆头部 117b能够旋转的范围。 当然， 也可以只设置一个阻挡部 127b， 以限制打开杠杆夹机构时杠
12 P2007441M 杆头部 117b能够旋转的范围。至于限制闭合杠杆夹机构时杠杆头部 117b能够旋转的范围， 可以通过使所述杠杆本体 117a抵靠基板 101 而实现。 优选地， 通过阻挡部 127b的限制使杠杆夹机构处于打开一 定范围的位置。
图 12-22显示了根据本发明第二实施例的杠杆夹机构 200。 根据 本发明第二实施例的杠杆夹机构 200 的结构与根据本发明第一实施 例的杠杆夹机构 100大体上类似，不同之处在于，只有在突起部 205d 朝向杠杆手柄部的一侧具有凹部 205e。 根据本发明第二实施例的杠 杆夹机构 200与本发明第一实施例的杠杆夹机构 100相同或类似的 部件用相同的标号加上 100表示， 并且省略对相同部件的描述。
在根据本发明第二实施例的杠杆夹机构 200中，环部件 205的两 个环部 205a在其接近基板的另一端通过连接部 205b—体地相互连 接。连接部 205b在其中部大体上水平地向着基板中心弯曲形成大体 上 U形弯曲部 205c， 弯曲部 205c中间部分略微向上突起形成突起 部 205d， 在突起部 205d的朝向杠杆手柄部 217c的一侧形成有凹部 205e。 在本发明的第二实施例中， 优选地， 在凸起部 209上更靠近 杠杆手柄部的一侧形成一个阻挡部 227b， 用于限制打幵杠杆夹机构 时杠杆头部 217b能够旋转的范围， 从而将杠杆夹机构限制在打开一 定范围的位置。 当然， 在凸起部 209上也可以与实施例 1相同的方 式设置两个阻挡部。
在图 17 所示的杠杆夹机构打开状态下， 通过握住杠杆手柄部 217c向下朝向基板转动杠杆 217， 可以使杠杆头部 217b绕着固定件
13 P2007441M 223从图 17所示状态顺时针转动，导致安装到杠杆本体 217a与杠杆 头部 217b的接合部处的辊子 219在环部件 205的弯曲部 205c上沿 着远离杠杆手柄部 217c的方向移动到突起部 205d ( SP，从凹部 205e 移动到突起部 205d)， 克服弹簧片 225的向上推力而将连接部 205b 压靠到基板 201上， 从而带动环部件 205的两个环部 205a—起移动 到与两个相对环部 203相接触的位置， 如图 13所示， 形成闭合环以 保持活页纸。
与此相反， 在图 13所示的杠杆夹机构闭合状态下， 通过握住杠 杆手柄部 217c向上远离基板 201转动杠杆 217，可以使杠杆头部 217b 绕着固定件 223从图 13所示状态逆时针转动， 导致安装到杠杆本体 217a与杠杆头部 217b的接合部处的辊子 219沿着朝向杠杆手柄部 217c的方向移离突起部 205d， 而松开对连接部 205b的压靠， 从而 使连接部 205b在弹簧片 225的向上推力作用下移离基板 201， 带动 环部件 205的两个环部 205a移离固定地安装的两个相对环部 203， 形成打开环以打开杠杆夹机构， 以便存取活页纸。
图 23-33显示了根据本发明第三实施例的杠杆夹机构 300。 根据 本发明第三实施例的杠杆夹机构 300 的结构与根据本发明第二实施 例的杠杆夹机构 100大体上类似， 不同之处在于， 凹部 305e设置在 远离杠杆手柄部的一侧， 并且， 杠杆本体 317a与杠杆头部 317b的 接合部通过诸如铆钉的固定件 323可转动地安装到凸起部 309上， 而辊子 （抵靠部） 319安装在杠杆头部 317b的自由端。 根据本发明 第三实施例的杠杆夹机构 300 与本发明第二实施例的杠杆夹机构
14 P2007441M 200相同或类似的部件用相同的标号加上 200表示，并且省略对相同 部件的描述。 下面详细描述根据第三个实施例的操作。
在图 24 所示的杠杆夹机构闭合状态下， 通过握住杠杆手柄部 317c向下朝向基板转动杠杆 317， 可以使杠杆头部 317b绕着固定件 323从图 24所示状态顺时针转动，导致安装到杠杆头部 317b的自由 端处的辊子 319在环部件 305的弯曲部 305c上沿着远离杠杆手柄部 317c的方向移动到凹部 305e ( gp，从突起部 305d移动到凹部 305e)， 松开对连接部 305b的压靠， 从而使连接部 305b在弹簧片 325的向 上推力作用下移离基板 301， 从而带动环部件 305 的两个环部 305a 移离固定地安装的两个相对环部 303， 形成打开环以打开杠杆夹机 构， 以便存取活页纸。
与此相反， 在图 27所示的杠杆夹机构打开状态下， 通过握住杠 杆手柄部 317c向上远离基板 301转动杠杆 317，可以使杠杆头部 317b 绕着固定件 323从图 27所示状态逆时针转动， 导致安装到杠杆头部 317b的自由端处的辊子 319沿着朝向杠杆手柄部 317c的方向移离凹 部 305e (即， 从凹部 305e移动到突起部 305d)， 克服弹簧片 325的 向上推力而将连接部 305b压靠到基板 301上， 带动环部件 305的两 个环部 305a—起移动到与两个相对环部 303相接触的位置，如图 27 所示， 形成闭合环以保持活页纸。
相对于现有的杠杆夹机构，根据第二和第三实施例的杠杆夹机构 由于在弯曲部 205c， 305c上设置了凹部 205e， 305e， 因此从打开位 置到闭合位置， 杠杆手柄部 217c， 317c的翻转角度明显比现有的杠
15 P2007441M 杆夹机构小， 使得杠杆手柄部 217c， 317c不会与夹内的纸张造成干 涉。 优选地， 在本发明中， 所述凹部 205e, 305e的深度被设置成使 得突出部 205d， 305d的最高点与凹部 205e， 305e最低点之间的距 离大于或等于制成环部件的钢丝的直径 D (如图 20B， 20C , 31B和 31C所示）。 另外， 优选地， 在本发明中， 所述凹部 205e， 305e 的 深度被设置成使得突出部 205d， 305d 的最高点与凹部 205e， 305e 最低点之间的距离大于或等于 4.5mm。
另外， 优选地， 本发明的杠杆夹机构的杠杆手柄部相对于杠杆本 体的倾斜角度尽可能小以便于手柄翘得较低。
尽管以上通过非限制性的方式结合附图详细描述了本发明的优 选实施例， 应当理解的是， 在不脱离本发明权利要求所限定的范围 的情况下， 可对本发明进行各种变换和修改。 例如， 在杠杆的端部 可以安装凸轮部以代替辊子。 此外， 还可以在相对的环部自由端设 置凸出部和凹入部， 以防止相互配合的环部脱开。 这些变换和修改 都应当落入本发明的保护范围内。
