车轮内胎与其安装方法
技术领域
本发明涉及车轮内胎与其安装方法， 特别是涉及一种脚踏车内胎与 其安装方法。 背景技术
一般轮胎可分为无内胎的轮胎与有内胎的轮胎。 具有内胎的轮胎， 以内胎作为充气之用， 一旦内胎因异物或其它原因造成破损， 便会导致 内胎消气。 一般常利用补胎的方式来修补内胎的局部破损， 但破损部分 过大或过多时， 则必须更换整条内胎。
传统内胎属于封闭环状， 因此更换整条内胎必须拆组轮圈， 此种情 形发生于比赛中时， 往往造成竞赛者耗时多， 甚至必须退出比赛。 台湾 新型专利号 M296165揭露一种长条形内胎，将充气阀设置于一端，另一 端有一接合设计， 例如一穿孔， 将该另一端固定于充气阔端。 台湾新型 专利号 M293857则是提供修补内胎的方式，在补胎过程中对于原为环状 的内胎先进行剪裁形成两端开口的内胎， 再将预先准备好的具有一封闭 侧端且一体成形的修补部分熔接于被剪裁的开口端。 前述第一种内胎， 对于个人的使用者而言， 一旦想更换不同尺寸的轮胎， 原先备用的内胎 会因尺寸不同而无法适用； 对于贩卖或修理业者、 比赛主办单位或是参 赛业者而言， 必须准备各种尺寸的内胎， 增加管理的成本。 前述第二种 为补胎的方法，需要准备剪裁原内胎的工具以及修补用的封闭侧端组件， 亦恐造成准备上的不便。 发明内容

优选地， 该第一侧端与该第二侧端中至少任一具有一等向渐缩的管 外径。
优选地， 该第一侧端与该第二侧端中至少任一具有一非等向渐缩的 管外径。
优选地，该第一侧端具有相对于该本体倾斜的一面以设置该充气阔。 优选地，该第一侧端具有相对于该本体垂直的一面以设置该充气阔。 优选地，多个突起设置于该第一侧端与该第二侧端中至少任一表面。 优选地， 该第二侧端具有与该本体密合的实心面。
优选地， 该第二侧端具有与该本体密合的实心结构。
本发明还提供一种车轮内胎， 其包括本体及充气阀， 其中该本体为 长条形中空管状， 该本体具有第一侧端与第二侧端， 其中该第一侧端与 该第二侧端为封闭的， 其是在成形过程中， 由一材料流动依序形成该本 体与该封闭的第一侧端与第二侧端， 并保留一开口； 应用时该第一侧端 与该第二侧端经过彼此后自由地与部分的该本体叠置以形成一可调整大 小的圆环， 以应用于至少二种不同轮径的轮胎； 该充气阀设置于包括该 开口上且与该本体密合。
优选地， 该第一侧端与该第二侧端中任一具有与该本体密合的实心 面。
优选地， 该第一侧端与该第二侧端中任一具有与该本体密合的实心 结构。
优选地， 该第一侧端与该第二侧端中至少任一具有一等向渐缩的管 外径。
优选地， 该第一侧端与该第二侧端中至少任一具有一非等向渐缩的 管外径。 本发明还提供一种安装车轮内胎的方法， 其包括：
提供一长条形内胎， 该长条形内胎具有一充气阀及一连接两侧端的 本体；
将该充气阀置放于一轮胎钢圈的一充气阀孔中， 并将该本体绕放于 该轮胎钢圈的一凹槽中， 使该两侧端经过彼此后各自叠置于部分该本体 上； 以及

图 9为本发明的安装车轮内胎的方法的较佳实施例的流程示意图。 具体实施方式
参照图 1， 为本发明的车轮内胎的第一实施例的外观示意图。 本发 明的车轮内胎 10的外观为一长条形，为了清楚说明内胎的特征，在此以 充气后的形式说明， 并应用长轴 X定义内胎本体 101的一长边方向， 以 短轴 Y定义内胎本体 101的一短边方向， 其中长轴 X与短轴 Y成正交； 可选择地， 长轴 X与短轴 Y亦可以成其它角度相交。 在第一实施例中， 内胎 10包括一充气阀 102，该充气阀 102设置于以长轴 X为法线方向的 一开口面 103上， 其中开口面 103位于内胎本体 101的一侧端， 即位于 内胎本体 101的长轴 X的第一侧端 104; 内胎本体 101的长轴 X的第二 侧端则具有一封闭结构 105。在本实施例中， 封闭结构 105为一实心面， 在内胎本体 101成形时与其一起形成， 例如以一体成形的方式形成内胎 本体 101及其封闭结构 105。 封闭结构 105亦可为一实心结构， 例如一 凸点或凸面， 其相较于图 1的实心面而言具有一定的厚度。 此实心结构 可以是内胎本体 101以适当方式成形时或成形后， 以原材料或其它材料 封住内胎本体 101的一开口使其封闭； 或是在内胎本体 101形成时， 材 料由流入口流动依序形成内胎本体与封闭结构， 成形后仅剩下开口面作 为与充气阀密合之用； 或是利用物理或机械力加工内胎本体 101的一开 口使其封闭； 或是利用化学方式修饰内胎本体 101的一开口使其封闭， 然而本发明不限于釆用上述方式形成实心结构。 上述不同的实心结构可 参考图 2的节点 205、 图 3的结点 305与图 4的盖体 405。
复参照图 1，充气阀 102设置于开口面 103上并与开口面 103密合， 内胎本体 101为中空状， 使用者可透过开口， 由充气阀 102对内胎本体 101充入流体， 例如空气填满中空部分或是释放流体。 充气阀 102可使 用现有的充气阀即可； 图 4中的充气阀 402亦设置于第一侧端 404的开 口面 403上。 可以理解， 当用以定义的长轴 X与短轴 Y的夹角非正交， 则开口面 103相较于长轴 X则为一倾斜面， 如图 2所示， 内胎 20的充 气阀 202仍可设置于内胎本体 201的开口面 203上。 另一实施例中， 如 图 3所示， 内胎 30包括一充气阀 302， 该充气阀 302设置于内胎本体 301的一开口面 303上， 开口面 303则是位于平行长轴 X的面上， 内胎 本体 301的第一侧端 304则具有另一封闭结构 306以封闭第一侧端 304， 此第一侧端 304与具有结点 305的第二侧端分别为内胎本体 101的两侧 端， 两侧端中间的内胎本体 301则由均一材料构成。 本发明中所谓的内 胎本体由均一材料构成， 可参照图 2中的环体 211、 212与 213。 多个紧 邻无缝的环体 211、 212与 213构成了本发明的内胎本体 201， 长轴 X 所指的方向为环体 211、 212与 213的法线方向， 环体 211、 212与 213 的直径位于短轴 Y方向。 本发明的这些例子中， 任一环体 211、 212与 213的材料都相同， 例如丁基橡胶。 其次， 封闭结构 305与 306的材料 亦与任一环体 211、 212与 213的材料相同。要说明的是， 图 2中的环体 211、 212与 213虽以相同的厚度（若以中空管视之， 或称为管壁）绘之， 但实际操作时， 可能于环体的外表面有脱膜线或凸状设计， 造成任一环 体本身的厚度或管外径有差异； 图 2的第一侧端 204具有非等向渐缩的 管外径， 同理第二侧端亦可具有非等向渐缩的管外径。 如图 3中的环体 311、 312与 313， 其中环体 313接近结点 305， 因此环体 313的厚度较 环体 311、 312大，但环体 313的管外径较环体 311、 312小， 且环体 313 的管外径为一等向渐缩的管外径， 但这一点并不造成本发明中所谓的内 胎本体 301由均一材料构成这一特征丧失。又如图 4所示， 内胎 40的环 体 413靠近内胎本体 401的盖体 405。若干突起 407设置于内胎本体 401 接近第一侧端 404与盖体 405处， 因此环体 413的厚度便与环体 412有 所不同， 即环体 411、 412与 413彼此的厚度有差异， 亦不造成本发明中 所谓的内胎本体 101由均一材料构成这一特征丧失。
要说明的是， 本发明的充气阀设置位置与封闭结构配置的模式并非 限于图 1至图 4的组合， 而是可以任意组合。 根据上述， 本发明提供的 长条车轮内胎， 可应用于各种不同尺寸的轮胎， 只要轮胎与内胎接触的 轮周长小于本发明的车轮内胎在长轴 X上的长度即可。 同时参照图 5与 图 6，轮胎钢圈 50的轮径大于轮胎钢圈 60的轮径，充气阔孔 501与 601 分别设置于轮胎钢圈 50与 60上。轮胎钢圈 50与 60分别安装于车架 54 与 64上， 且分别套接一外胎 52与 62， 内胎 56则安装于轮胎钢圈 50或 60的凹槽中， 其可被充气并被外胎 52或 62所覆盖， 充气阀 561则可由 充气阀孔 501或 601穿出轮胎钢圈 50或 60以供充气或放气之用。 同时 参照图 7与图 8， 当充气阀 561设置于内胎 56的一侧端 562， 或称固定 端时， 内胎 56的本体沿着轮胎钢圈 50、 60放置， 内胎 56的另一封闭侧 端 563， 或可称为自由端， 绕过充气阀孔 501、 601后继续地沿着轮胎钢 圈 50、 60放置， 因此， 内胎 56于轮胎钢圈 50与外胎 52之间有部分叠 置； 同理， 内胎 56于轮胎钢圈 60与外胎 62之间亦有部分叠置。可以理 解， 由于轮胎钢圈 50与 60的轮径不同， 故内胎 56叠置的长度亦不同。 由于轮胎钢圈 50的轮径大于轮胎钢圈 60的轮径，因此内胎 56于轮胎钢 圈 60上叠置的部分较长。 要说明的是， 内胎 56叠置部分的质量或许较 未叠置部分大， 但一旦内胎 56被充气后，使用者未必会感受到上述的质 量差异。 其次， 因气体本身具有流动的特性， 在内胎 56被充气后， 内胎 56的叠置部分中的气体， 并不会造成该叠置部分与未叠置部分所构成的 胎压有明显地不同。 且因内胎 56的外表面尚有外胎 52与 62， 即便有些 微的胎压差异， 使用者亦未必感受到该胎压差异。
请参照图 9， 现再将本发明中有关安装车轮内胎的方法的一较佳实 施例， 整理如下所述：
步骤 70: 开始；
步骤 71 : 提供一长条形内胎， 该长条形内胎具有一充气阀及一连接 两侧端的本体；
歩骤 72: 将该充气阀置放于一轮胎钢圈的一充气阀孔中， 并将该本 体绕放于该轮胎钢圈的一凹槽中， 使该两侧端经过彼此后各自叠置于部 分该本体上； 以及
步骤 73 : 将一外胎固定于该轮胎钢圈上， 其中该长条形内胎被局限 于该轮胎钢圈与该外胎之间；
歩骤 74 : 结束。
因此， 根据上述， 本发明的长条车轮内胎， 可在不需拆组车架上的 轮轴的情形下， 更换原本的内胎。 其次， 一长条车轮内胎可适用于不同 尺寸的轮胎， 只要确保轮胎钢圈的周长小于长条车轮内胎即可， 不需因 轮胎尺寸的不同而配置不同长度的长条车轮内胎， 只需准备少数不同长 度的内胎， 每一种长度可分别应用于若干不同轮径的轮胎， 备用上更为 便利。 再者， 本发明的长条车轮内胎的使用方法， 以部分叠置的方法取 代现有的两末端接合方法， 在安装时只需确保自由端于内胎绕行轮胎钢 圈后超过固定端放置的位置即可， 在使用上更为便利。
在本发明以部分实施例的方式进行讨论时， 本领域普通技术人员应 可了解本发明并非如此受限。 此处的实施例是由实例进行解释， 而在本 发明的范围之内还有许多的修改、变化或是其它实施例， 可增加、移除、 及 /或重组元件。 此外， 亦可增加、 移除、 或是重新排序处理步骤。 许多 不同的设计及方式亦为可行。
