球拍网弦调整定位器
技术领域
本发明涉及一种球拍网弦调整装置， 特别是一种对球拍使用后网弦位置 错乱的调整和定位的工具。 背景技术
在网球和羽毛球等网弦球拍在拍击球的体育运动中， 由于网弦受球的频 繁撞击， 使本来排列整齐网弦产生移动而使网孔逐渐移动并变得疏密不均， 影响击球质量。 为了使网弦球拍重新恢复击球质量， 亦即是使网弦恢复到正 确的位置上， 很多年来人们进行了孜孜不倦的创新， 发明出很多的网弦调整 工具。
最常用的网弦调整工具是单个的定位柱， 例如 US2005/0159254A公开的 拍弦调整装置， 通过与用力方向相反逐渐增大的边或面对球拍网孔进行四边 挤压。 由于考虑到单个的定位柱的使用效率及基准的确定等问题， 而出现了 平面基座上 4非列定位柱的调整工具， 例如 US4089523A、 US4989864A , US4489942A, US5823900A, US5441258等等披露的那样, 它们的共同之处是， 釆用几乎与球拍网弦区特别是中心区域大小一致的基板， 基板上具有与所在 区域网孔完全对应的定位柱， 每个定位柱与网孔大小完全对应， 通过对球拍 网孔进行四边挤压而完成调整。
然而， 不同 球^、、 至同一 球^内的不同弦孔 ^在着 ^寸差别 特 的不同， 这种不同源于球拍的加工造成的不一致； 当把网弦调整工具使用在 不同的球拍时， 或当把工具制造的小一些而需要在同一张球拍适当移位使用 时， 所述每孔差别尺寸的累积， 导致某些定位柱不能进入弦孔而顶弦线上而 无法进行调整。 因此前述的大基板式的工具存在兼容性差、 携带不方便等缺 陷。
人们当然注意到球拍网孔不一致的问题， FR2749178A3公开一种中间区域 定位柱截面呈方形， 上下区域定位柱截面呈条形， 并呈人字形排列的调整工 具， 显然， 这也是为特定球拍量身定做的， 兼容性差、 体积大携带收藏不方 便。
还有一些能够部分克服上述不足的发明， 例如 US4733866提出了一种由 若干可更换的定位柱单排固定在定位槽中构成的调整工具， 通过将定位柱呈 与正常孔位一致安装在定位槽中， 由于横向孔、 纵向孔均要不同设置， 使用 艮麻烦， 而且单排定位柱定位并不准确。 虽然 US2661102 着重考虑了定位柱 对球拍网孔的适应性， 即定位柱可以做一定弧度的摆动以适应不同的孔位， 但其结构复杂， 甚至有卡线的弊端。 综上所述， 现有技术中的调整工具要么存在使用效率的问题， 费时费力， 调整出来的网孔大小不均， 影响击球质量。 要么存在兼容性差的问题， 针对 性太强， 不利于工业化批量生产。 因此艮难找到一种对球拍弦网各个区域的 网孔进行正确调整的工具， 或找到一种可以对多种球拍的网弦进行方便调整 的工具。 发明内容
针对现有技术存在的上述不足， 本发明的目的是提供一种球拍网弦调整 定位器， 它可以在同一球拍的不同网孔区进行有效调整使用， 还能在同规格 的不同球拍上使用， 调整方便， 兼容性强。
本发明首先是基于申请人特别观察到， 背景技术中的定位柱大多强调四 边对网孔的同时挤压， 而球拍的网孔除了如前所述的大小不均外， 在正常状 况下， 所有网孔的横向宽度是大致一样的， 变化多的是纵向的长度， 此外， 观察发现， 球拍在使用中由于纵向的弦线较长， 又由于人体手臂的自然挥拍 方向， 在上拉球和下切球时容易发生纵向弦线位置的横向左右偏移， 而横向 的弦线相对来说不易发生上下的位置变化。
针对上述现象， 本发明釆用了这样的技术方案， 即一种球拍网弦调整定 位器， 其特征是： 包括按纵横排列或纵横间隔排列的若干调整定位柱， 每个 调整定位柱的至少一个正立面投影面的最大宽度与球拍正常网孔的横向宽度 尺寸相对应， 调整定位柱通过所述最大宽度两端的面或点对称压挤横向给力 使相邻网弦之间距离恢复到正常； 当这种作用在一根弦线上直线多点对称给 力时， 就能调整偏移的弦线被直线定位， 当调整多根弦线时， 则使多根弦线 直线定位和间隔定位； 每两列调整定位柱的列间距离或同一行两调整定位柱 最大宽度之间的距离与球拍网弦的直径对应。
所述按纵横排列或纵横间隔排列的若干调整定位柱安装在基座上， 或与 基座加工为一体。
进一步地， 每个调整定位柱下部的两个高度上具有两个呈 90° 排列的通 孔分别为横向穿孔和纵向穿孔； 若干个调整定位柱的横向穿孔通过横向轴串 成一列， 若干列调整定位柱通过若干通过纵向穿孔及纵向轴串成调整定位柱 矩阵， 调整定位柱之间的间隔由增加垫片或垫块实现。
更进一步， 所述调整定位柱的矩阵安装在基座上。
前述的基座和调整定位柱由塑料或铝合金材料通过模具压铸做成的； 或 由具有一定硬度和韧性的轻质材料或轻质复合材料制造。
进一步地， 基座是扁的方形、 长方形、 圓形、 椭圓形或八边形； 基座的 底面是平面、 曲面或圓弧面。
或者在上述基座的底面和至少一个侧面安装或 /和成型调整定位柱， 安装 或成型在基座侧面的调整定位柱为至少一个或至少一行。 当然， 基座还可以由主基座和辅助基座构成， 安装或成型在辅助基座上 的调整定位柱为至少一个或至少一行； 主基座和辅助基座呈一定夹角固定或 成型为一体， 或辅助基座在主基座的一端与其铰接， 通过旋转锁定机构选择 辅助基座与主基座在同一平面上或在不同的平面上。
进一步地， 基座侧面安装调整定位柱（为可收进和伸出的结构。
上述基座上设有适合于手握住推拉用力的把手， 把手为与基座固定的把 手， 或为收折式把手、 卡接式把手； 或基座的两侧设置抓手的能推拉用力的 防滑槽。
前述纵横间隔排列的若干调整定位柱的间隔排列须满足： 间隔为一条直 线， 直线两边的定位柱至少两点或三点对称， 以使其中的网弦获得左右的向 中推力。 基于上面相同的设计理念， 本发明还包括一种球拍箱包， 它包括能 装进球拍头部的上盖和下盖构成的箱包壳体， 其特征在于： 所述下盖在安放 球拍的区域内， 按纵横排列或纵横间隔排列安装有若干与球拍网孔对应的调 整定位柱； 上盖设置有能与球拍网线框的内边沿对应的压环， 所述调整定位 柱安装或成型 在基座上， 所述基座的周边具有对应球拍内框边沿的坡面， 坡 面使球拍居中固定。 当球拍放入箱包内时， 通过上盖的压环下压网弦， 让调 整定位柱进入对应的网孔中， 而使网孔得到调整和定位。
综前所述， 由于每孔差别尺寸的累积， 使定位器上的某些定位柱压向弦 线而不是弦孔， 致使全部定位柱都不能进入弦孔。 由于研究发现了拍弦偏移 主要发生在纵向拍弦的横向偏移上， 而改进后的定位器， 定位柱纵向宽度小 于网孔尺寸， 适当的纵向移动就能使定位柱避开了阻挡的弦线而致使全部定 位柱同时进入弦孔。
由于调整定位柱横截面逐渐增大， 端部面积小， 便于插入已经变小的网 孔， 将调整定位柱插入网孔内， 以压挤方式逐渐深入， 网孔被调整定位柱撑 大， 使尺寸变小的网孔逐渐扩大， 直至调整定位柱深入至某位置处时， 此位 置调整定位柱的大小与正常网孔尺寸大小相对应， 网孔恢复正常大小， 完成 拍弦调整。
由于釆用了上述技术方案， 本发明的优点是非常显著的： 即当球拍弦线 偏移后， 通过调整定位柱最大宽度两端的面或点对称压挤横向给力并与相邻 两边的定位柱对称压挤横向使相邻网弦之间距离恢复到正常， 并且当这种作 用在一根弦线上直线多点对称给力时， 就能调整偏移的弦线被直线定位， 当 调整多根弦线时， 则使多根弦线直线定位和间隔定位。 由于在纵横之一方向 一定范围解决了因弦线排列间隔不同造成的定位柱进入阻碍， 所以， 本发明 使定位器兼容性提高 50%、 体积和重量减轻 80%成为可能。 从而， 有利于工业 批量制造和降低制造成本， 有利于实现一个定位器适用于多个球拍， 有利于 大大改小定位器便于携带而又不影响使用效果。 附图说明
