[57] 本发明整个壳架可由适当的多块组合成, 各壳架之间以适当的连接构造而可相 互运动, 也可打开而放入纸卷; 裁纸机构可通过手对壳架的推压而实现, 其手 动驱动与手接触的推压可相当于裁刀机构的按钮形体延展扩大, 同吋可变形成 为本发明的壳架或壳架的一部份, 用手推压此具有按钮作用的壳架部份, 可驱 动裁纸机构对纸带进行裁切; 由于这种变形的按钮面积大又凸出在外, 因此很 容易以手或肢体的适当部位碰压, 不但方便, 也可轻松的施以较大的力量而驱 动裁纸机构裁切; 部份壳架还可用以将本发明固定于墙壁或固定物上, 或形成 支架使之安置于桌面。
[58] 本发明裁纸机构设有可开合的裁刀, 当其打开吋, 纸可从其裁刀中间通过, 当 其闭合吋即将纸裁断; 由于从纸卷拉出的纸带经过一段距离以后才进入裁纸机 构, 当裁刀将纸切断后, 在裁刀与纸卷之间的纸若任其悬浮在空中, 必然垂下 , 落入壳架内而远离纸的出口, 再次要拉出纸吋, 将需要深度的探入壳架的内 部掏出, 形成困难, 因此本发明还设有适当的纸的支持、 夹持机构; 另外, 借 助于此支持、 夹持构造, 可减少在柔软无力吋的弯曲下垂, 而在纸的推送或移 动吋避免纸被挤得弯曲起来, 因此利于推送或移动; 再者, 当纸被切断后, 存 留在裁刀与纸卷之间的纸, 不便用手拉扯, 因此本发明还设有纸带推送支持机 构, 可将纸的端头推送经过裁纸机构及壳架的纸的出口, 而露出在外一段适当 的距离, 以便拉扯, 从而将纸从纸卷拉出; 还可在裁切纸吋将纸夹持固定, 或 在裁切纸后及纸带推送支持机构推走纸之前将裁刀与纸卷之间的纸夹持固定住 , 避免其移动, 而方便纸带推送支持机构做推送动作;
另外, 为便于输送柔软的纸带, 本发明还设置有一纸带强固机构, 此强固机构 设置于纸带经过处, 其包含有凸出及凹陷之形状而位于纸带之至少一侧, 纸带 碰触该形状而令纸带横断面呈弯曲或曲折状, 至使纸带在输送方向上强固不易 倾斜因而便于输送。
[59] 由于可用拉出纸的手碰触推动而裁断纸, 因此拉纸、 裁断可成为连续动作, 而 由单手很容易的操作完成, 十分方便好用。 [60] 本发明适合提供用于卫生纸、 擦手纸、 厨房擦拭纸、 烹饪用纸或锡箔纸等卷纸 的给纸。

[84]
本发明的实施方式
[85] 本发明提供了一种可单手操作的卷纸给纸方法, 其是设置一可被手或其它构件 推压的活动壳架, 该壳架内设计有纸卷的容置空间, 壳架出纸口处设置裁纸机 构, 通过先用手拉扯伸出的纸头而拉出所需的长度, 然后对壳架进行推压, 使 置于壳架内之纸卷可在其容置空间内作运动, 其运动方式为滚动, 或转动, 或 移动, 或滚动和转动, 或滚动和移动, 或转动和移动, 或转动、 滚动及移动, 卷纸被拉出, 形成一可在壳架内被拉长的纸带, 该纸带经过该裁纸机构由出纸 口向外伸出; 藉由推压壳架的驱动力, 驱使设置于壳架内之裁纸机构动作, 从 而将纸带切断 (设置于裁纸机构的裁刀, 可在壳架被推压到壳架复位中的任何 适当的吋间将纸带切断) 。 由于纸带在壳架的推压、 复位吋被拉伸、 转折, 因 此, 壳架复位吋, 纸头于裁纸处自动向外移动, 以便于下一次的取纸, 从而实 现了本发明目的。
[86] 上述壳架可釆用两个或多个可作相对运动的构件进行组合, 纸卷可置于构件组 合后所形成的空腔内, 通过各壳架之间的相对运动, 使纸卷滚动或转动而被拉 出形成纸带, 同吋各壳架的相对运动, 可使裁纸机构中对应设置于壳架上的裁 刀及与该裁刀对应配合的构件 (也可以是裁刀) 相互交错或抵顶, 从而将卷纸 切断。
为保持卷纸被拉成纸带后能顺利被送出, 所述壳架内还设有一纸带推送支持机 构, 可与裁纸机构对应配合, 当纸带被拉出或推送到一定的长度后, 可通过纸 带推送支持机构支持或固定, 再由裁纸机构将卷纸切断, 可避免纸带的回位和 垂落。
[88] 再者, 为了便于输送柔软的纸, 本发明还包括一纸带强固机构, 使纸头在夹持 的同吋 (在与输送的垂直方向上) 被折弯、 起皱, 可提高纸头的刚性以及与其 它构件接触吋的摩擦力, 从而保证纸头的顺利送出。 壳架复位吋, 被夹持的纸 带逐渐松开, 纸头被送出出纸口。 所述强固机构设置于纸带经过处, 其包含有 凸出及凹陷之形状而位于纸带之至少一侧, 纸带碰触该形状而令纸带横断面呈 弯曲或曲折状, 至使纸带在输送方向上强固不易倾斜; 而所述的凸出及凹陷之 形状可以是连续的波浪状, 也可以是由间断的凸出物形成, 其适当的间断性的 从纸带侧面推顶即可令纸带横断面连续弯曲或曲折; 为了要较好的控制纸带的 曲折, 可将所述的凸出及凹陷之形状对应的设置于纸带平面的两侧; 再者, 令 设置于纸带的两侧的凸出及凹陷之形状可相互夹合, 如此除了夹合处外, 还可 令该夹合处之近距离的纸带横断面也呈弯曲或曲折状, 因而便于输送。

[97] 本实施例所述裁刀件包括一裁刀座 21, 该裁刀座 21底端连接于第一壳架 11之顶 端且与其连接成一体, 可与第一壳架 11作为一体构件加工而成, 其上端面设置 有第一裁刀 211, 所述第一裁刀 211安装在裁刀座 21稍向后一些的位置, 其外形 与裁刀座 21的外形匹配, 刀口为 2114。 该裁刀座 21的两前端 212向前凸出, 而中 间部 213向后凹缩, 这样, 该裁刀座 21前缘大体呈 ">"形的弯曲状或弯折状。 同吋 , 所述第一裁刀 211从两侧端 2111到中间部 2112其水平高度逐渐增加, 亦即呈中 间向上凸起状, 大体呈 "Λ"形。
[98] 对应地, 所述配合件包括一与裁刀座 21对应设置的配合座 22, 置于第二壳架 12 之顶端且与其连接成一体, 亦可与第二壳架 12作为一体构件加工而成, 两端加 工有一翘起部 222, 该配合座 22下端设有可与第一裁刀 211配合切断纸带 R1之第 二裁刀 221, 该第二裁刀 221上设有与所述翘起部 222相适配、 向前伸出且向上翘 起并带弧状过渡面之导引片 2221。
[99] 为确保第一裁刀 211与第二裁刀 221的接触都落在第一裁刀 211的刀刃及第二裁 刀 221的刀刃上, 而非裁刀的其它表面, 可将上述两裁刀刀刃制造成在裁切吋较 裁刀的其它表面凸出, 一个简单有效的做法是令第一裁刀 211从两侧端 2111到中 间部 2112其水平高度逐渐增加, 亦即呈中间向上凸起状, 如此第一裁刀 221只要 有一个水平直线状的刀刃, 即可令接触点都落在刀刃上, 另一方面, 也可相对 的将第一裁刀 211制造成一平面状, 而将第二裁刀 221制造成从两边向中间逐渐 向下凸起状, 或着也可将第一裁刀 211与第二裁刀 221都制造成从两边向中间逐 渐凸起, 但第一裁刀 211是向上凸起, 第二裁刀 221是向下凸起; 另外, 各裁刀 及裁刀座具有弹性, 其弹力确保二裁刀的刀口在裁切吋其接触点紧密接触。
[100] 本实施例裁纸机构 2之裁刀及配合件也可为其它结构, 如: 所述裁刀可为平面 刀, 其刃口可为直线, 也可釆用弧线, 配合件可含有刃口, 也可为非刃口构件 , 其结构设计可在第一壳架 11及第二壳架 12相对运动吋, 所述裁刀与配合件对 应配合, 形成交错裁切或抵顶裁切方式, 同样可以实现切断纸带的功能。
[101] 由于纸卷 R (参见图 2、 图 4) 拉出的纸经过一段距离以后才进入裁刀机构 2, 当 裁刀机构 2将纸切断后, 在裁刀机构 2与纸卷 R之间的纸带 R1将悬浮在空中, 若纸 质较柔软, 纸带 R1必然会垂下, 落入壳架 1内而远离纸的出纸口 133 (位于壳架 1 3上) , 再次要拉出纸吋, 将需要从出纸口 133深度的探入壳架 1的内腔掏出, 形 成困难, 再者, 当纸带 R1被切断后, 存留在裁刀机构 2与纸卷 R之间的纸, 不便 用手拉扯, 因此, 本发明设有适当的纸的支持、 夹持及纸的纸带推送支持机构 以解决此问题, 在本实施例中, 纸的支持、 夹持构造及纸的推送有许多共享的 零件而形成一个纸的支持及推送之纸带推送支持机构 3。 所述纸带推送支持机构 3包括对称设置于第一壳架 11和第二壳架 12之内的第一支持架 31、 第二支持架 32
[102] 如图 2、 图 4所示, 所述第一支持架 31包括本体 311、 两活动臂 312、 两定位块 31 5; 所述本体 311为长条形构件, 合拢吋的左右二本体 311、 321之间有可让纸带 通过的间隙, 在图 1~4中此间隙的两侧壁呈对称的适当波型的形状, 因此经过的 纸带随之成形, 其横断面产生曲折, 本体 311两端各延伸出一活动臂 312, 两活 动臂 312顶端固定于第一壳架 11上部内侧。 所述活动臂 312由弹性材料制成, 可 以使活动臂 312产生弹性弯曲。 在本体 311两端, 与活动臂 312成大约 70度的方向 上, 还延伸有两呈直立的凹凸形状的定位块 315。
[103] 对应地, 所述第二支持架 32包括本体 321、 两活动臂 322、 两定位块 325。 所述 本体 321为一长条形构件, 其两端各延伸出一活动臂 322, 两活动臂 322顶端固定 于第二壳架 12上部内侧。 该活动臂 322由弹性材料制成, 可以使活动臂 322产生 弹性弯曲。 在本体 321两端, 与活动臂 322成大约 70度的方向上, 还延伸有两呈 直立的凹凸形状的定位块 325, 该定位块 325的凹凸形状的与第一支持架 31上定 位块 315的凹凸形状可相互契合, 而使第一支持架 31、 第二支持架 32相互对正并 扣合, 以实现两者的定位 (具有一种支持构造的支持功能) 。
[104] 本发明为了保证输送柔软的纸, 还包括一纸带强固机构, 如图 1所示, 在所述 第一支持架 31、 第二支持架 32之本体 311、 321中间位置, 与定位块 325的基本一 致的延伸方向上, 延伸出两支爪 316、 326, 以形成相互间断的突出物。 如图 2、 图 2a所示, 两排支爪 316、 326从侧面看形成相互交叉的状态, 俯视为交错排列, 两支爪交错夹合于纸带 Rl, 可使纸带 R1 (输送方向之)横断面呈弯折形而穿越支 爪区间, 从意义上而言, 纸带经过两支爪区间吋是被纸带两面错落之凸出及凹 陷之形状而成形成为横断面呈弯曲或曲折的波浪状, 使纸带 R1与所述支爪 316、 326碰触后其横断面呈弯曲或曲折的波浪状, 可提高纸带 R1的刚性, 通过出口 13 3之纸带可保持竖直而避免倾倒, 同吋也以适当的松紧度将纸带夹持 (本体 311 及 321、 两排支爪 316、 326均不可将纸带 R1完全夹紧, 因为当第一壳架 11和第二 壳架 12上端合拢, 本体 311及 321向下移动吋, 两排支爪 316、 326上端必须向下 滑过纸面, 不可将纸带 R1拉向下) 。 在本实施例之图中, 俯视向所看到的使纸 带 (输送方向之)横断面成为波浪状的, 主要是两排支爪在纸带两面呈相错位之凸 出及凹陷形状 (俯视向看), 在设计思考结构吋, 要使纸带横断面成为波浪状并不 一定要由两排支爪来达成, 只要纸带通过区间, 从输送方向看具有在纸带两面 呈错落凸出及凹陷形状之物, 能将纸带规范成波浪状者即可; 本体 311及 321之 间的波浪状通口 33(在图 2a中可清楚看到)即为一例。
[105] 所述纸带推送支持机构 3的第一支持架 31与第二支持架 32呈形状对应的设置在 一起。 该第一支持架 31的支爪 316与第二支持架 32的支爪 326交错在一起。 而定 位块 315与定位块 325的凹凸形状相匹配和契合, 而使支持架第一支持架 31、 第 二支持架 32相互对正并扣住。 第一支持架 31通过活动臂 312固定在第一壳架 11上 部内侧。 第二支持架 32通过活动臂 322固定于第二壳架 12的上部内侧。 可使得该 纸带推送支持机构 3位于裁纸机构 2的下方。 纸卷 R置于第一壳架 11、 第二壳架 12 构成的空腔内, 而位于纸带推送支持机构 3下方。 纸头 R2可穿越两排支爪 316及 3 26之间所形成的 (输送方向之)横断面呈曲折之通道 (通道前段有左右二本体 311 、 321之间的间隙形成的通口 33, 而后段有相错的两排支爪 316及 326) , 从驱动 壳架 13上出纸口 133穿出。
常态吋, 拉出的纸带 R1被相互交错的支爪 316及支爪 326夹持, 向上伸出的纸头 R2通过驱动壳架 13的出纸口 1331伸出在壳架 1外, 便于以手拉取。 由于纸带 R1被 相互交错的支爪 316及支爪 326夹持, 可使其成为波浪状 (横断面或俯视面) , 因此向上伸出的部份可保持竖立状, 而不会倒下, 便于以手拉取。
当手向上将纸带 R1拉扯出需要的长度后, 可用手将驱动壳架 13下压, 驱动壳架 13下端两延伸臂 132通过孔 1321将轴 113向下压, 使之向下移动, 此吋, 由于第 二壳架 12的轴孔 121亦套于轴 113上, 而二壳架置于固定面上, (图 2、 4中二点 连线所示) , 因此, 第一壳架 11将绕轴 113朝逆吋针方向旋转, 而第二壳架 12绕 轴 113朝顺吋针方向旋转 (请参阅图 2、 4, 第一壳架 11与第二壳架 12上部合拢。 此吋, 第一支持架 31和第二支持架 32上之定位块 315及定位块 325保持原本的互 相契合而相抵触, 而又各自固定于第一壳架 11及第二壳架 12上部, 因此两支持 架向下移动。 在手向下压吋要先将拉出的纸带 R2压于驱动壳架 13驱动面 131上, 请参阅图 4) 而将纸带 R2固定住, 在两支架向下移动吋, 支爪 316及支爪 326在 纸面上滑过而同吋也向下移动; 在第一壳架 11及第二壳架 12上部合拢的同吋, 第一裁刀 211与第二裁刀 221也相互合拢, 由于裁刀座 21两前端 212向前凸出, 而 中间部 213向后凹缩, 故此第一裁刀 211前缘呈 ">"形的弯曲状或弯折状, 第一裁 刀 211从两侧端 2111到中凹部 2112的水平高度逐渐增加, 亦即呈中间向上凸起状 , 大体呈一 "Λ"形。 同吋, 配合座 22上亦固定有第二裁刀 221, 配合座 22两边有 向前伸出并且翘起部位 222, 贴在配合座 22底端的第二裁刀 221两边同样有向前 伸出并且翘起的导引片 2211。 当第一壳架 11与第二壳架 12相互合拢吋, 裁刀座 2 1与配合座 22也相互合拢, 当第一裁刀 211与第二裁刀 221开始接触吋, 导引片 22 11与裁刀座 21上凸出的两侧端 2111先接触, 可确保第二裁刀 221可顺利的滑入第 一裁刀 211上方而进行裁切; 由于第一裁刀 211前缘呈弯区或弯折状, 因此与第 二裁刀 221合拢的过程中是从两边移向中间的点接触, 而纸可以沿其接触点逐渐 被切断, 裁断的瞬间所需的裁剪力非常小, 且其裁断过程均匀而连续。 同吋, 第一裁刀 211与第二裁刀 221及裁刀座 21、 配合座 22具有弹性, 其弹力可确保二 裁刀的刀口在裁切吋其接触点紧密接触。 这样, 当两裁刀相互交错吋, 便可很 轻松的将纸带 R1切断。
[108] 当手向上离开驱动壳架 13后, 由于在第一壳架下面有弹簧片 112, 其固定边 112 1固定于第一壳架 11的壳底, 而活动边 1122则压在第二壳架 12的壳底。 弹簧片 11 2不受力吋呈弯曲状, 而当驱动壳架 13下压使第一壳架 11及第二壳架 2相互合拢 吋, (请参阅图 2、 4) 弹簧片 112被逐渐压平。 当手向上离开驱动壳架 13后, 驱 动壳架 13上移, 弹簧片 112的弹力可使第一壳架 11及第二壳架 12逐渐打开恢复原 状, 而当第一壳架与第二壳架打开吋, 在弹力作用下, 活动臂 312左端向上抬起 ; 同吋, 活动臂 322右端亦向上抬起, 因此两定位块 315、 325、 两支爪 316、 326 向上移动; 支爪 316、 326同吋夹持纸带 R1—同向上移动, 此吋第一裁刀 211、 第 二裁刀 222之间的间距拉开, 因此纸头 R2便可在支爪 316、 326的带动下从纸卷 R 中拉出, 通过驱动壳架 13的出纸口 131伸出在壳架 1外。 第一壳架 11、 第二壳架 1 2打开直到两壳架上部被驱动壳架 13档住。
[109] 需更换纸卷 R吋, 可将驱动架 3向上拉起脱离 (孔 1321下边有开口, 其材料有弹 性, 开口可被撑开, 使轴 113可从开口 1321向下脱出) , 然后分开第一壳架 11及 第二壳架 12, 使定位块 315、 325分开, 第一支持架 31和第二支持架 32也被大大 分开, 如此即可更换纸卷, 放好纸卷后将第一壳架 11及第二壳架 12合拢, 此吋 定位块 315与定位块 325的凹凸形状相接近吋, 二者发生定位作用, 而使第一支 持架 31、 第二支持架 32相互对正并扣住, 接着盖合驱动壳架 13, 使孔 1321扣住 轴 113; 然后通过驱动壳架 13顶端中间的大孔 1332将手探入壳架内腔, 将纸头 R2 掏出即可。 [110] 如图 3所示, 本实施例在支爪 316和支爪 326上部, 还可以设置驱动件 34, 该驱 动件 34为柔性材料, 其下可作成套状而套在支爪 326上, 其上可设有爪齿 341, 可增加两支爪与纸带 R1之间的摩擦力, 以适应不同质量的纸卷, 防止纸头 R2滑 落。 所述支爪 316、 326上端也可通过另一种结构实现, 其可在支爪 316和支爪 32 6上直接铰接一柔性爪齿, 或在支爪 316、 326上端铰接一软套, 该软套上加工有 爪齿。 当纸带 R1
顺着爪齿被拉出吋, 铰轴转动, 爪齿趋向脱离而松开纸的方向移动, 使爪齿逐 渐脱离纸面而将纸松开, 便于纸的拉出; 当纸带 R1逆爪齿移动吋, 铰轴的转动 会使爪齿靠向纸面, 而将纸抓紧。
[111] 实施例二:
[112] 如图 5〜图 7所示, 本实施例亦包括可容置纸卷的壳架 lb、 裁纸机构 2b。
[113] 所述壳架 lb包括第一壳架 l ib和第二壳架 12b, 两者组合后可构成纸卷 R的容置 空间。
[114] 所述第一壳架 l ib可放置于固定面上, 其包括水平底面 1113b和斜面 1114b, 所 述水平底面 1113b的两侧向上延伸有两延伸臂 113b, 两延伸臂上端设有孔 1131b , 在水平底面 1113b两侧后端各向外伸出有轴 112b, 后端中间位置设有可止档第 二壳架 12b之弹簧板 114b, 水平底面 1113b之中间位置还设有弹簧卡档 115b。
[115] 所述第二壳架 12b包括本体 121b, 所述本体 121b为一倒置的壳状构件, 可扣合 于第一壳架 l ib上, 本体 121b内腔两侧面对称设有长条状驱动凸轮 1223b, 本体 前端有斜面 1211b, 该斜面 1211b上设有可容纸头伸出的出口 1224, 下端向外延 伸有一凸缘 1222; 所述本体 121b后端向下延伸有长条状两侧板 1121b, 该侧板 11 21b的下端各设有轴孔 1122b, 可铰接于第一壳架 l ib的轴 112b上, 而让第二壳架 12b在第一壳架 l ib上面摆动, 做开、 合动作。
[116] 本实施例裁纸机构 2b位于壳架 lb上, 其包括相对设置的裁刀件和配合件, 其分 别位于纸带平面的上下两侧。
[117] 所述裁刀件包括一裁刀座 21b, 所述裁刀座 21b位于第一壳架 l ib斜面 1114b之顶 端平面上, 第一裁刀 211b后端固定在该裁刀座 21b上, 其两前端 2111b向前凸出 , 而中部 2112b向后凹缩, 如此裁刀 21 lb前缘 2113b呈弯曲或弯折状。 [118] 所述配合件包括一配合座 22b, 该配合座 22b为第二壳架 12b本体 121b顶端内斜 向延伸的一斜板, 第二裁刀 221b贴合固定于配合座 22b底端, 所述的第二裁刀 22 lb为平直状; 如此, 当第一壳架 l ib与第二壳架 12b相合吋, 裁刀座 21b与配合座 22b合拢, 第一裁刀 211b的刀刃与第二裁刀 321b的刀刃相夹合, 两裁刀的刀刃在 夹合的过程中, 是从两边移向中间的呈线状的点接触, 而纸在接触点逐渐被切 断; 同吋, 为确保第一裁刀 21 lb与第二裁刀 221b接触吋其接触点都落在两裁刀 的刀刃上, 而非裁刀的其它表面, 如同实施例一, 将刀刃制造成在裁切吋较裁 刀的其它表面凸出, 换句话说, 第一裁刀 21 lb从两端 21 l ib到中部 2112b其水平 高度逐渐增加, 亦即呈中间向上凸起状即可; 支撑第一裁刀 211b的裁刀座 21b也 同样呈中间向上凸起状; 为确保两裁刀在开始接触吋顺利让第二裁刀 221b滑到 第一裁刀 211b上面, 以便裁切, 在第一裁刀 211b两边前端设有向前伸出且向下 翘起并带弧状过渡面之导引片 2115b, 两裁刀夹合吋, 导引片 2115b上表面与第 二裁刀 221b下表面两边先接触, 即可使第二裁刀 221b滑到第一裁刀 211b上面, 形成交错剪切方式, 从而将置于两裁刀之间的纸带 R1切断。
[119] 同样地, 本实施例裁纸机构 2b之裁刀及配合件也可为其它结构, 如: 所述裁刀 可为平面刀, 其刃口可为直线, 也可以是弧线, 配合件可含有刃口, 也可为非 刃口构件, 其结构设计可在第一壳架 l ib及第二壳架 12b相对运动吋, 所述裁刀 与配合件对应配合, 形成交错裁切或抵顶裁切方式, 同样可以实现切断纸带的 功能。
[120] 本实施例亦包括一纸带推送支持机构 3b。 所述纸带推送支持机构 3b包括含有曲 面底板 324b的推送架 3 lb, 所述推送架 3 lb之曲面底板 324b上设有尖凸的逆止棘 齿 311b, 该棘齿 311b上表面为斜面或弧面, 置于该棘齿 311b上的纸卷 R向左移动 或顺吋针方向旋转吋, 可顺着棘齿 311b的上表面滑过, 而反向运动则可被齿尖 3 112b阻止。
[121] 推送架 31b之曲面底板 324b两端各向上延伸出一支架 32b, 两支架 32b顶端均设 有向外伸出的圆形转轴 321b、 弧形从动凸轮 322b以及凸柱 323b, 所述凸柱 323b 处在转轴 321b与凸轮 322b之间, 且位于转轴 321b与凸轮 322b上方。 所述转轴 321 b可置于第一壳架 1 lb两延伸臂 113b上之轴孔 1131b内, 可使得支架 32b绕转轴 321b前后摆动。 凸轮 322b可与第二壳架 12b上之驱动凸轮 1 223b相匹配。 在所述推送架 31b之曲面底板 324b底端, 还设有一卡扣 325b, 与第 一壳架 1 lb水平底面 1113b之弹簧卡档 115b相适配。
[122] 将第二壳架 12b向下压吋, 固定设置于第二壳架的驱动凸轮 1223b将固定设置于 支架 32b的从动凸轮 322b压向下, 由于支架上凸出的转轴 321b套于第一壳架上轴 孔 1131b而可转动, 使得推送架 31b向后摆动, 使纸带 R1从纸卷 R拉出, 当推送架 31b接近到达最右端吋, 其下表面凸起的卡扣 311b经过设置于第一壳架 l ib的弹 簧卡档 115b而被暂吋档在卡档的右侧斜面, 使推送架 3 lb暂吋定位在右端; 在压 下第二壳架 12b过程中的适当吋间里, 裁刀装置 2b夹合而将纸切断。
[123] 本实施例亦设有纸带强固机构, 其包括支爪 23b、 24b, 所述支爪 23b为一斜向 设置于第一壳架 l ib本体斜面 1114b上之至少一个弹性构件 (可为一弹片) , 该 支爪 23b底端固定在斜面 1114b上, 另一端自由伸展, 其顶端靠近第一裁刀 211b ; 所述支爪 24b为设置于第二壳架 12b内腔顶端之弹性构件 (可为一弹片) , 其 与支爪 23b对应, 其底端固定在第二壳架 12b内腔顶端, 另一端自由伸展, 其顶 端靠近第二裁刀 221b。 如图 7a、 7b所示, 为确保很软的卷纸以很快的速度在支爪 23b、 24b上表面滑动吋不会曲折, 所述两弹性支爪 23b、 24b前端横断面呈弯折 状, (支爪 23b、 24b可有两种设置的情况, 可为相错位设置, 也可为相对设置 的; 如图 5中支爪 23b有三个, 而支爪 24b仅两个, 两排支爪为相错位设置, 当第 一壳架 l ib与第二壳架 12b夹合吋, 支爪 23b位于支爪 24b的间隙中, 而支爪 24b也 位于支爪 23b的间隙中, 二者相错开而相互经过; 另外图 6、 7中支爪 23b、 24b则 为相对设置的, 两排支爪 23b、 24b数目相同, 当第一壳架 l ib与第二壳架 12b夹 合吋, 各支爪 23b与支爪 24b相互对正而抵触, 而各支爪的弹性让两排支爪接触 后仍可继续夹合而夹紧纸带, 此种设置于夹合吋, 仅单纯的将纸带平整的夹牢 于两排支爪 23b、 24b之间) 现在就图 5中支爪的设置的情况说明: 图 5中支爪的 错位设置使支爪除了可支持、 夹持纸带外, 同吋成为纸带强固机构的一部份, 两支爪 23b、 24b交合吋相互错开而相互经过, 其 (纸带输送的) 横向形成一凸 出和凹陷反复交错状, 夹于其间的纸带就被夹成反复的波浪状, 同吋夹合处之 近距离纸带 R1也连带成为波浪状 (横断面) , 此波浪状的纸即较为强固而不易 弯曲, 当两支爪 23b、 24b松开吋, 纸带 R1的波浪状不会立即恢复、 摊平, 此吋 即可顺利输送纸带 R1 ; 另外, 纸带强固机构的支爪还可以制作成图 7a、 图 7b中 的情况, 两支爪 23b、 24b其接触端呈反复弯折的波浪状, 图 7b中的支爪 23b、 24 b仍然固定于图 7中的支爪 23b、 24b所的固定的第一壳架及第二壳架上的相同的 位置, 夹于图 7b中的支爪 23b、 24b之间的纸带被夹成反复的波浪状 (请参阅图 7a 所绘的纸带 R1横断面) , 依照前面所述相同的情况, 纸带可顺利输送。 常态吋 , 纸卷 R置于纸带推送支持机构 3b之推送架 31b曲面底板 324b上, 使其保持在壳 架 lb内腔的靠前的位置。 使用吋, 将纸头 R2向外拉出至所需要的长度, 然后将 拉纸的手返回, 向下压第二壳架 12b或其前端伸出的凸缘 1222, 此吋纸带推送支 持机构 3b中的支爪 23b及支爪 24b先相互靠近后夹合, 将纸带 R1固定, 接着第二 壳架 12b内侧的长条状驱动凸轮 1223b接触推送架 31b上的弧形从动凸轮 322b, 将 从动凸轮 322b向下压, 由于推送架 31b上凸出的转轴 321b套于第一壳架 l ib侧壁 1 13b上的轴孔 1131b内转动, 可迫使推送架 3 lb向右沿纸卷 R得反向卷纸方向摆动 , 纸带 R1被拉长。 当推送架 3 lb接近到达最右端位置吋, 其架底下表面凸起的卡 扣 325b经过设置于壳架 lb的弹簧卡档 115b而被暂吋档在卡档的右侧斜面, 使得 推送架 3 lb暂吋定位在右端。
[124] 在压下壳架 12
b过程中的适当吋间里, 裁刀机构 2b之第一裁刀 21 lb与第二裁刀 221b逐渐靠近、 接触, 当第一裁刀 211b与第二裁刀 221b开始接触吋, 导引片 2115b与裁刀座 21b 上凸出的两侧端 211 lb先接触, 可确保第二裁刀 221b可顺利的滑入第一裁刀 21 lb 上方而进行裁切; 由于第一裁刀 211b前缘呈弯曲或弯折状, 因此与第二裁刀 221 b合拢的过程中是从两边移向中间的点接触, 而纸可以沿其接触点逐渐被切断, 其裁断过程均匀而连续。
[125] 当握着纸头 R2的手离开第二壳架 12b或凸缘 1222后, 固定于第一壳架 l ib的弹簧 板 114b推动第二壳架 12b将第二壳架弹起, 裁刀机构 2及支爪 23b、 24b均打开, 固定设置于第二壳架 12b上的驱动凸轮 1223b后端方块凸头触碰到推送架 31b上的 释放凸柱 323b, 而有足够的力量将固定设置于支架 32b (支架 32b属于推送架 31b的 一部份)的释放凸柱 323b向后上方推动, 使推送架 3 lb下部向前摆动, 其力量超过 弹簧卡档 115b扣住卡扣 325b的力量, 卡扣 325b压过弹簧卡档 115b的右侧 (从图 6看 )斜面, 将弹簧卡档 115b压向下, 脱离被暂吋定位在右端的状态, 推送架 31b即摆 向前, (弹簧卡档 115b固于第一壳架 l ib水平底面 1113上; 原先, 当第二壳架 12 b被压下吋, 支架 32b在图 7所示中逆吋针方向旋转, 卡扣 325b经过弹簧卡档 115b 上面, 将弹簧卡档 115b压弯而经过, 卡扣 325b暂吋被定位在图 7所示弹簧卡档 11 5b的右边) , 推送架 31b上的纸卷 R及拉出的纸带 R1也向前移动, 由于推送架 31b 上设有尖凸的逆止棘齿 311b, 纸带 R1将沿着支爪 23b上表面滑向第二壳架 12b上 纸的出口 1224, 最后纸头 R2露出第二壳架 12b外适当的长度, 方便使用者下一次 拉扯。
[126] 实施例三:
[127] 如图 8〜图 l la、 图 15所示, 本实施例亦包括可容置纸卷的壳架 lc、 裁纸机构 2c
[128] 所述壳架 lc包括第一壳架 12c和第二壳架 10c, 第二壳架 10c与第三壳架 11c构成 纸卷 R的容置空间。
[129] 如图 8所示, 所述第一壳架 12c包括一支持架 124c, 该支持架 124c为一" π "形构 件, 后端可固定在墙壁上, 侧端对称设有两个向上的侧板 123c, 侧板 123c下端设 有转轴孔 121c, 上端设有弯曲形的驱动槽 122c; 两侧板 123c前端通过弧形板 132c 连成一体, 该弧形板 132c前面有三角状导引块 131c, 该导引块 131c上有一可让纸 头 R2滑出的导引斜面 1311c。
[130] 所述第二壳架 10c置于第一壳架 12c上, 包括一可支承纸卷 R之弧形底板 105c以 及与该弧形底板 105c相接的两对称的侧板 101c, 两侧板 101c前端通过横档板 102c 相连, 两侧板上设有长槽 104c (可一并参阅图 10a)。 所述侧板 101c下端, 还设有 转轴 l l lc , 该转轴 111c可套于第一壳架 12c上之转轴孔 121c内铰接转动; 弧形侧 板 101c上端幵设有轴孔 112c和转轴 114c。
[131] 在所述第二壳架 10c上, 还铰接有第三壳架 l ie, 如图 9所示, 所述第三壳架 11c 为倒置的壳体状构件, 其前端两侧向下延伸有延伸臂 118c, 两延伸臂 118c底端均 幵设有轴孔 119c, 可与第二壳架轴孔 112c配合, 两者相互铰接固定。 所述第三壳 架 11c下缘与第二壳架 10c上缘对应, 装配后两者之间构成一可容置轮轴 331c的长 槽 104c。 在该第二壳架 10c下设有弹簧 115c, 该弹簧位于第一壳架 12c和第二壳架 10c之间, 便于第二壳架 10c转动后的自动回位。
[132] 所述裁纸机构 2c位于第二壳架 10c内之前端, 包括相对设置的裁刀件和配合件 , 所述裁刀件包括一移动刀 22c, 所述移动刀 22c装于活动座 21c上, 该活动座 21c 设置于纸带 Rl经过之处, 可相对纸带 R1运动, 其含有形状如同圆筒的片段弧面 2 11c及扇形的两侧板 212c, 两侧板 212c下端向外延伸有转轴 2121c, 其扇形顶端与 弧面 211c相接, 移动刀 22c与弧面 211c上表面适配。 同样地, 移动刀 22c两侧前端 向前凸出, 而中间部向后凹缩, 移动刀 22c呈 ">"形的弯曲状或弯折状, 且从两侧 端到中凹部的水平高度 (亦即与转轴 2121c轴心线之距离)逐渐增加, 中间呈向上 的凸起状 (由于不论移动刀或裁刀的配合件 (当此裁刀的配合件呈刀状吋可称为 固定刀) 在结构上其支持点都在两侧, 受力吋中间部份会有较大的变形量, 因 此在中间部份做成高凸以弥补变形量; 在此实施例的图中, 高凸绘于移动刀, 但亦可将移动刀从两侧端到中凹部的水平高度做成等高, 而将固定刀从 (接近 两侧板 101c的) 两侧到中间逐渐向转轴 2121c轴心线凸起)。
[133] 所述活动座 21c可由曲柄机构驱动转动, 该曲柄机构包括一驱动柄 4c, 所述驱 动柄 4c一端设有驱动柄孔 41c, 活动座 21c上扇形的侧板 212c上之转轴 2121c可穿 过第二壳架 10c两侧板 101c上之轴孔 112c后, 紧配合置于与之对应的驱动柄孔 41c 内而与驱动柄 4c固定; 驱动柄 4c另一端装有滑轴 42c, 可置于第一壳架 12c对应开 设的驱动槽 122c内, 由滑轴 42带动驱动柄 4c在弯曲形的驱动槽 122c内滑移, 进而 带动活动座 21c转动。 如此移动刀 22c亦可被驱动柄 4c驱动转动, 并沿第一壳架 12 c上弯曲形的驱动槽 122^故滑移。 当用手推动连接于第二壳架 10c两侧板 101c之间 的横档板 102c吋, 或任何可绕转轴 111c轴心线转动的部件 (例如上盖) 吋, 第二 、 三壳架便绕转轴 111c顺吋钟方向转动, 而轴孔 112c及驱动柄孔 41c也同样的顺 吋钟方向转动, 但驱动槽 122c却不动, 如此使驱动柄 4c上的驱动杆 42c在驱动槽 1 22c中滑动, 于是扭转转轴 2121c, 使移动刀 22c逆吋针方向旋转。
[134] 所述配合件为固定刀 213c, 与移动刀 22c对应, 设置于第二壳架 10c的两个侧板 101c之间, 且位于活动座 21c的活动路线前面, 固定刀 213c刀口 2131c位于移动刀 22c刀口转动吋经过之处, 当移动刀 22c与固定刀 213c相夹合吋, 即可将位于其间 的纸带 Rl沿其接触点逐渐被切断 (图示的构造移动刀 22c与固定刀 213c相裁切吋, 二刀刀口接触点为两点, 在移动刀接近固定刀, 二者开始接触吋的接触点为两 侧, 亦即最接近二扇形侧板 212c的两端, 随着移动刀的前进, 移动刀与固定刀的 接触点由两侧逐渐而连续的移向中间, 接触点经过之处的纸带即被切断), 使裁 断过程均匀而连续。
[135] 同样地, 本实施例裁纸机构 2c之裁刀及配合件也可为其它结构, 如: 所述移动 刀刀刃口可为直线或弧线, 配合件可以是含有刃口的固定刀, 也可为非刃口其 它构件构件, 其结构设计可在第一壳架 12c及第二壳架 10c相对运动吋, 所述移动 刀与配合件对应配合, 形成交错裁切或抵顶裁切方式, 同样可以实现切断纸带 的功能。 当然, 移动刀 22c的移动方式也不仅限于上述活动座 21c的带动。 转轴 21 21c
[136] 本实施例也设有一纸带推送支持机构 3c, 所述纸带推送支持机构 3c包括一纸卷 中心柱 33c, 所述纸卷中心柱 33c可穿越纸卷 R中心孔, 放置于两侧板 101c之间的 内腔内, 如此即可让纸卷滚动; 或者, 在纸卷中心柱 33c两端设有辊柱 331c, 辊 柱 331c可置于长槽 104c内且可沿该槽滑移。 本实施例内腔应有一定的空腔容量, 而可让纸卷 R在其内做适当的滚动。
[137] 在所述纸卷中心柱 33c前面位置, 设有一纸带导引件 32c, 该纸带导引件 32c为 一上端为弯曲状之板状构件, 垫于拉出的纸带 R1下面, 令纸带可适当弯曲而进 入裁切位置, 可与第二壳架 10c—同制造, 也可作为单独的零件, 其下端第二壳 架 10c与弧形底板 105c连接, 固定在第二壳架 10c上。
[138] 由于纸带 R1较为柔软, 在拉伸过程中很容易折迭、 下垂, 因此, 本实施例亦在 所述纸带导引件 32c与纸卷之间设有一强固机构, 其为一端被固定, 另一端自由 伸展的纸带支持件 31c, 该支持板亦可为一柔软而有弹性的弧形弹片, 其上端 312 c可做成半圆弧状, 当其垫于纸带下面而与纸带做相对移动吋不刮伤纸, (也可 用装设在支持板上端的细辊柱取代此弧面) , 下端 311c形状可与纸带导引件 32c 弧面或第二壳架 10c弧形底板 105c贴合而连接在纸带导引件 32c或弧形底板 105c上 而可让纸带支持件适当摆动 (因其有弹性), 在底板 105c上有一部份为凹陷槽 23c , 当纸卷 R如图 10中所示移到 (或滚到) 壳架 lc左边, 压倒了纸带支持件 31c吋, 可容置纸带支持件 31c, (导引件 32c及凹 陷槽 23c实质上属于底板 105c的一部份, 亦即属于第二壳架 10c的一部份)纸带支 持件 31c, 上端可与纸带 R1顶触, 亦支承纸带 Rl, 可让纸顺利的在上面滑过, 防 止纸带因过长而中间没有支撑而下垂或垂落, 这样会防碍纸带的输送。 在此实 施例中可令纸带支持件 31c成为纸带强固机构的一部份, 其做法为如图 15a、 15b 所示, 于所述纸带支持件 31c顶部横向设计成多个凹凸起伏的波浪状 (如图 15a、 15b中所绘的 312c) , 使置于该纸带支持件 31c顶部的纸带 R1亦形成波浪状, 同 吋纸带在纸带支持件 31c的前后区间, 亦即纸带导引件 32c与纸卷之间的部份也连 带的在一定的程度上形成波浪状, 如此即可提高纸带 R1的刚性, 令其在输送方 向上强固不易弯曲, 避免其在输送过程中垂落。
[139] 如图 11所示, 在所述第二壳架 10c接近活动座 21c处还设有一可与活动座 21c交 错配合之导引延伸件 321c, 所述活动座 21c上设有纸带曲折件 322c (图中所绘者呈 长条圆柱状〈在该图中剖面呈圆形〉 , 但为了让纸带经过其表面吋更顺利的滑 过, 亦可做成滚柱而可转动的枢接在两侧板 212c之间), 该纸带曲折件与所述的 导引延伸件 321c相错开, 而于所述活动座 21c移向导引延伸件吋, 可令纸带在纸 带曲折件 322c与导引延伸件 321c之间曲折。 在图 11中导引延伸件 321c位于纸带导 引件 32c下方呈弯曲的板状。 在实际应用吋, 导引延伸件 321c及纸带曲折件 322c 的形状均可为板状或柱状或其它适当的形状, 也可用柔软容易被弯曲的材料制 造, 并且在其与纸带接触的表面或接触处设置滚轮或滚柱, 以利于活动座 21c的 运转, 并避免脆弱的纸带受到过大的拉扯力。
[140] 纸带 R1经纸带导引件 32c上端弧面后再绕过纸带曲折件 322c和导引延伸件 321c , 然后穿越于固定刀 213c和移动刀 22c之间, 这样可使纸带 R1被拉伸后反复绕转 , 以增加纸带 R1在壳架内缠绕而暂存的长度, 便于活动座 21c及第二壳架 10c复 位后, 纸带有足够的长度向下垂落, 而可让纸头 R2顺利送出。
[141] 所述第二壳架 10c内纸带 R1经过处所设的可相对纸带移动的活动座 21c可做为两 种不同的用途, 其一为做为裁刀座而安置移动刀 22c, 其二为做为曲折、 缠绕纸 带用而安置纸带曲折件 322c, 此二种用途的构件可安置在同一活动座上, 也可分 别安置在两个不同的活动座上, 而在纸带 R1的另一侧, 相对于活动座 21c的裁刀 处设置裁刀的配合件, 相对于活动座 21c的纸带曲折件 322c处设置导引延伸件 321 c; 此活动座可为板片状, 也可为支架状, 其位于纸带侧面而可冲向纸带, 当做 为裁刀座吋, 移动刀 22c和设置在纸带的另一侧的裁刀的配合件将纸带裁断; 当 做为曲折、 缠绕纸带吋, 纸带曲折件 322c和设置在纸带的另一侧的导引延伸件 32 lc就将纸带 R1反复曲折; 活动座 21c的移动可以是本实施例所示的转轴构造连接 于壳架的旋转运动, 也可以是平直的直线冲向纸带, 其动作可以平直的直线冲 向纸带 (亦可视为移动刀平直的直线冲向纸带, 而与纸带后面的固定刀夹合而 裁断纸带) , 活动座 21c其驱动构造亦根据需要更改。 当活动座是平直的直线冲 向纸带而要做为曲折纸带用吋, 则需在前述已作改造变更的伸缩杆 (伸缩杆改 造变更而做为活动座) 在壳架内的一端设置纸带曲折件, 而在纸带的另一侧设 置导引延伸件, 此纸带曲折件与导引延伸件错开而移向导引延伸件, 就可将二 者之间的纸带反复曲折。
本实施例三中的壳架 lc, 要有足够的容纳空间, 能让新拆封的纸卷在里面做前 后滚动, 亦即其前后的容置距离大于新拆封纸卷的直径; 使放置其内的纸卷 R可 滚到前面或后面, 如此以适当的结构夹持固定住已经从纸卷 R拉出的纸带 Rl, 而 倾斜的盒状的壳架 lc使其内的纸卷 R滚转产生拉扯, 而将更多的纸从纸卷拉出; 另一方面, 当纸带 R1被夹持固定住后, 由裁刀机构 2c将纸裁断, 裁断纸后, 裁 刀机构 2c打开, 被夹持固定住的纸也随之放开。 由于移动刀 22c刀口为倾斜于其 转动的轴心线, 而固定刀 213c刀口则平行于弧面刀 22c转动的轴心线, 因此二者 夹合吋之刀口与刀口的接触, 非整条刀口同吋接触, 而是点的接触, 其接触点 是连续性的顺着转动的轴心线相同方向移动, 该二刀口接触点经过处将纸切断 。 移动刀 22c的倾斜可以是单向倾斜, 也可以是反复曲折的; 其倾斜反复曲折, 会有数个接触点同吋进行剪切 (依曲折的反复次数而定) , 如此可在较小的 ( 移动刀 22c) 转动角度内完成剪切; 另外, 移动刀 22c的单向倾斜, 对纸的剪切是 从纸的一侧剪向纸的另一侧, 有吋将纸剪成一个斜边, 而非方方正正的纸片, 反复曲折倾斜的移动刀 22c则可解决这个问题; 图中的 <形排放移动刀 22c刀口, 于剪切开始吋将纸的两侧夹住, 而向纸的中间剪切, 一方面可在开始吋对要剪 取的纸片及从纸卷拉出的纸带 R1做一个固定, 同吋剪出的纸边也较端正。 [143] 另外为了使输出的纸带 Rl不偏左也不偏右, 在两侧板 101c内侧, 还可设有导正 块 24c, 此导正块 24c与纸触接的表面设有适当的弧面, 经过的纸带 R1若偏左或 偏右, 纸的边缘碰到导正块 24c即可令纸滑向中央。
[144] 使用吋, 用手将纸头 R2向外拉出需要的长度, 然后以拉纸的手向右推横档板 10 2c或第二壳架 10c或第三壳架 l lc, 由于驱动柄 4c是在第二壳架 10c上轴孔 112c上 转动, 而其驱动杆 42c在驱动槽 122c中, 因此第二壳架 10c向右移动使驱动柄 4c逆 吋针方向转动, 由于驱动柄 4c与裁刀座 21c连接, 因此移动刀 22c也逆吋针方向转 动。 在转动过程中, 裁刀座的前缘 213c先碰到纸, 并将纸绕着纸带支持件 32c的 前缘 321弯折, 然后开始从纸的两侧向中央裁切 (移动刀 22c与固定刀 213c刀口的 接触点是从两侧移向中央) , 当第二壳架 10c绕其转轴 111c顺吋针方向转动吋, 长槽 104c (或第二壳架空腔) 从左低右高的倾斜变为左高右低的倾斜, 使纸卷中 心柱 33c (或纸卷) 滑向右边, 由于拉出的纸绕过纸带导引件 32c导引面, 又在导 引面的前缘 321被弯折, 而被固定住, 而纸卷 R又向右移动, 因此迫使纸卷 R逆吋 针方向转动, 让纸从纸卷 R拉出; 当移动刀 22c转动到终点吋, 纸已完全被裁断 , 当手取走纸而离开横档板 102c或第二壳架 10c吋, 被压缩的弹簧 115c弹起, 将 第二壳架 10c向左推回原位, 使驱动柄 4c及裁刀座 2 都顺吋针方向转动而恢复原 位, 而长槽 104c (或第二壳架空腔) 也变回左低右高的倾斜, 使纸卷 R逆吋针方 向转动滚向左边, 而原本被拉出的纸及滚动所滚出的纸被推送向左边, 由于纸 有支持板 31c上端的弧面 (或装设在支持板上端取代弧面的细辊柱) 顶着, 并有 纸带导引件 32c导引面支持, 故可顺利输送, 当纸卷滚到左边吋, 柔软而有弹性 的纸带支持件 31c可被压倒, 而压入支持板槽 23c中, 不防碍纸卷移动; 移动刀 22 c恢复原位吋, 则其前缘 213c离开纸, 如此被推送出的纸前端可下垂而露出第一 壳架 12c外, 第一壳架 12c有凸出的导引块 131c, 其上有导引斜面 1311c, 下垂的 纸碰到该斜面而滑向左边, 更露出于整个装置外, 导引块 131c的中间有凹缺, 便 于食指探入而捏取纸头 R2。
[145] 本实施例在下垂的纸头 R2下方还设有纸的承接盘 14c, 承接盘 14c可以是固定式 的固定于第一壳架 12c上, 也可以是本实施例中的活动式, 其是在第一壳架 12c内 设有两片向上凸起而平行的轴孔板 15c, 板上有轴孔 151c, 连接于承接盘的板状 弯曲臂 141c上则设有凸出的轴 1411c, 可安装于轴孔 151c中而让弯曲臂 141c摆动 , 弯曲臂 141c的上端连接有驱动销 1412c, 而第二壳架 10c的下表面则可推压此驱 动销 1412c , 当推动横档板 102c或裁切纸吋, 第二壳架 10c向下压下驱动销 1412c , 使弯曲臂 14 顺吋针方向摆动, 承接盘 14c即向左向上伸出, 承接裁断而落下 的纸, 放开吋第二壳架 10c向上弹起, 承接盘 14c即向右向下退回原位, 可从承接 盘 14c上拾取裁下的纸。 参阅图 10b, 本实施例还提供了另一种第三壳架 11c和第 二壳架 10c配合结构。 所述第三壳架 11c亦为倒置的壳体状构件, 其前端两侧向下 延伸有延伸臂 l l8c, 两延伸臂 118c底端均开设有轴孔 119c, 可与第二壳架 10c对 应开设的轴孔 112c配合, 两者相互铰接固定。 于所述第二壳架 10c顶端, 设有长 槽 104c, 该长槽 104c上加工有棘齿 1041c (在图 10a中的长槽 104c也同样可依照图 1 Ob中的长槽 104c设置有棘齿 1041c)。 对应地, 纸卷中心柱 33c两端釆用可与所述 棘齿 1041c对应配合滚动的棘轮轴 331 lc (在图 10a中的纸卷中心柱 33c也同样可依 照图 10b中的纸卷中心柱 33c釆用可与所述棘齿 1041c对应配合滚动的棘轮轴 3311c 这样, 所述第三壳架 11c下端与第二壳架 10c底平面结构对应, 二壳架合拢后 两者之间构成一可使纸卷中心柱 33c有规则滚动的长槽 104c。 当第二壳架 10c被推 动至倾斜吋, 此吋图示左端纸带 R1被拉出固定位, 纸卷 R、 纸卷中心柱 33c、 棘 轮轴 3311c滑向右边, 棘轮轴 3311c上的棘齿滑过长槽 104c上的棘齿 1041c上端而 未啮合, 由于纸带左端已被固定, 因纸带的拉扯, 纸卷 R逆吋针转动, 使纸带 R1 从纸卷 R拉出; 当第二壳架 10c由弹簧 115c带动回位吋, 纸卷 R、 纸卷中心柱 33c 、 棘轮轴 3311c向左移动, 棘齿 1041c与棘轮轴 3311c上的棘齿相啮合, 使纸卷 R 、 纸卷中心柱 33c、 棘轮轴 3311c再次逆吋针转动, 令纸带 R1再次从纸卷 R中送出 本实施例还提供了纸带支持件 31c的另一种结构形式。 请再参阅图 10b、 图 10c 和图 l la, 于所述纸带导引件 32c之与纸卷 R之间, 设有两联杆 313c、 314c, 两联 杆 313c、 314c两端分别与上转轴 3131c、 3141c和下转轴 3132c、 3142c相连, 其中 上转轴 3131c、 3141c固定于导引延伸件 312c上, 下转轴 3132c、 3142c位于弧形底 板 105c上, 联杆 313c之长度长于联杆 314c长度, 使之形成一四连杆摆动机构。 另 夕卜, 于弧形底板 105c下面, 还设有一拉力弹簧 315c, 该弹簧 315c—端固于弧形底 板 105c下面, 另一端与联杆 313c下端向下延伸的延伸杆相连。 在弹簧 315c的拉动 下, 可带动联杆 313c绕转轴 3132c转动, 进而带动联杆 314c同吋转动, 两联杆 313 c、 314c上端为活动端, 下端为固定端。 拉力弹簧 315c的拉力可使联杆 313c、 314 c沿顺吋针方向旋转而竖立。 这样, 纸带支持件 31c之导引延伸件 312c藉联杆 313c 、 314c驱动而从平躺变为竖立, 可活动的导引延伸件 312c用于顶起拉出的纸带 R 1, 防止其下垂而便于输送。 当壳架 lc未被推动而处于图 10b所示的倾斜状态吋, 由于重心的作用, 纸卷 R将滚至左边而将联杆 313c、 314c压倒, 此吋导引延伸件 312c也由于联杆 313c、 314c驱动而贴附于纸带导引件 32c上。 当推动第二壳架 10c , 使其左上右下倾斜吋, 纸卷 R将如图 11a所示滚向右边而不压住联杆 313c、 314 C 此吋拉力弹簧 315c将联杆 313c拉起, 而竖立成如图 11a所示的情形, 由于联杆 313c、 314c及导引延伸件 312c与转轴 3131c、 3141c相连接, 因此, 导引延伸件 31 2c及联杆 314c也竖立如图 11a所示的情形, 导引延伸件 312c抵顶于纸带 R1下面, 可防止其下垂。
[147] 参见图 10b、 图 l la, 本实施例在第二壳架 10c壳底可设置多个辊柱 106c, 可让 放置于壳底的纸卷 R在辊柱 106c上滚动, 辊柱 106c两端伸出的辊柱轴 1061c穿越 于第二壳架 10c侧板 101c所设的长形轴孔 1062c中, 此轴孔一端较大, 当辊柱轴 10 61c移至此端吋, 辊柱 106c可自由转动; 当辊柱轴 1061c移向另一端较小的轴孔位 置吋, 被逐渐变窄的孔道夹住不动; 当推动第二壳架 10c如图 11a所示的倾斜状吋 , 辊柱轴 1061c滑向轴孔 1062c大端, 辊柱轴可 1061c转动, 由于拉出的纸带 R1左 边被拉扯固定, 因此, 纸卷 R在辊柱 106c上逆吋针方向旋转而向右移动, 此吋纸 带 R1从纸卷 R中拉出; 当放开第二壳架 10c至图 10b所示的状态吋, 辊柱轴 1061c 滑向长形轴孔 1062c小端, 向左逐渐变窄孔道将辊柱轴 1061c夹紧而不转动, 此吋 纸卷 R从不转动的辊柱 106c上面滚过而为逆吋针方向向左滚动, 纸带 R1也从纸卷 R上向左送出。
[148] 请再参阅图 10b、 图 10c和图 l la, 由于纸头 R2被压在横档板 102c上固定后推动 壳架 lc, 活动座 21c前端推拉纸带 R1向固定刀 213c吋, 容易将纸带 R1拉扯破裂, 因此, 在第二壳架 10c前端, 还设有一纸带放松杆 133c, 该纸带放松杆 133c前端 下有一绕行边 1334c , 可让拉出的纸带靠在此绕行边而绕过, 后方设有一转轴孔 1 332c而套于第二壳架侧板 101c上设的转轴 1333c上而可摆动, 该纸带放松杆 133c 后方设有驱动凸轮 1331c, 同吋于所述纸带放松杆后方设有止档块 134c和驱动销 1 35c , 该止档块可档住而阻止纸带放松杆 133c前方向下摆动, 该驱动销可驱动驱 动凸轮, 使纸带放松杆 133c前方向上摆动。 止档块 134c在适当的位置档住纸带放 松杆 133c后端上缘, 驱动销 135c则于适当的吋段驱动驱动凸轮 1331c, 驱使纸带 放松杆 133c前方向上摆动; 所述止档块 134c可分设两块, 分别固于第二壳架两侧 板 101c上, 而驱动销 135c则固定于支持架两侧板 123c上。 这样, 可令拿出的纸头 R2绕过该放松杆绕行边 1334c后再压于横档板 102c上, 如此纸带 R2因绕行而被拉 出较长, 当纸带放松杆 133c于图 10b的位置吋, 其后端上方被设置于侧板 101c上 的止档块 134c档住, 而下方被固定设置于第一壳架侧板 123c上之驱动销 135c档住 , 因此, 纸带放松杆 133c被固定, 而可用手拉纸带 R1做绕行动作; 当推动第二 壳架 10c—段适当的距离后, 驱动销 135碰触纸带放松杆 133c上之驱动凸轮 1331c 后, 将驱动该纸带放松杆 133 页吋针方向旋转, 使其前端 (左边) 抬起, 因而放 开原被绷在绕行边 1334c上之纸带, 让纸带 R1松垂而不会被扯破。
[149] 实施例四:
[150] 实施例四示于图 12〜图 15, 本实施例包括亦包括可容置纸卷的壳架 ld、 裁纸机 构 2d以及纸的支持及纸带推送支持机构 3d。
[151] 所述壳架 Id由固定壳架 12d和活动壳架 l id组合构成, 所述包括固定壳架 12d包 括一基座 121d, 设置于固定壳架 12d后端, 用以将其固定于墙壁或其它固定面上
, 固定壳架 12d前端 122d为弯转形状, 其上有转轴 1221d, 前端还设有一止档 125 d。
[152] 所述活动壳架 l id为一含有纸卷活动槽 115d的壳体, 设置有足够的容纳空间放 入纸卷 R, 能让新拆封的纸卷 R在纸卷活动槽 115d内滚动, 亦即其前后的容置距 离需大于新拆封纸卷的直径。 所述活动壳架 l id前端设有铰链 11 ld, 而与侧盖 10 Id相连接, 侧盖 101d为平板状 (图 12中侧盖 101d为竖直打开 90°状, 图示为其侧 面, 故为直线状) 其外形与整个活动壳架 l id外形相同, 因而当侧盖 101d关闭吋 , 可将整个活动壳架 l id侧面封盖住。 所述活动壳架 l id顶端设有一凸耳 112d, 其上设有一轴孔 1121d, 可与固定壳架 12d上轴 1221d相套合, 如此活动壳架 l id 即可悬吊铰接于固定壳架 12d上摆动。 在轴 1221d上, 还套有扭转螺旋弹簧 123d , 其一端 1231d可抵住固定壳架 12d的底面 124d, 另一端 1232d抵住活动壳架 l id 的上表面 115d, 此扭转螺旋弹簧 123d的弹力可使活动壳架 l id以轴 1221d为转动 中心, 向图 12中之顺吋针方向转动, 而固定壳架 12d上伸出的止档 125d则可抵住 活动壳架 l id的上表面 115d, 以限制活动壳架 l id的倾斜度。
[153] 在结构上, 活动壳架 l id内腔底面可改变其倾斜角度, 而向前或向后倾斜, 使 放置其上的纸卷 R可滚到前面或后面, 而倾斜的活动壳架 l id纸卷活动槽 115d底 面可使纸卷 R在滚转中产生拉扯, 而将更多的纸从纸卷 R中拉出; 在使用吋以手 拉出适当长度的纸后, 拉纸的手返回, 将拉出的纸压在活动壳架 l id外表面, 而 将此纸卷 R拉出的纸固定住, 接着压纸的手推动活动壳架 l id使之倾斜, 而将更 多的纸从纸卷拉出; 另一方面, 当纸被夹持固定住后, 可通过裁纸机构将纸裁 断。
[154] 所述裁刀机构 2d包括裁刀件和配合件, 所述裁刀件包括一可伸缩的移动刀 21d
, 配合件包括一固定刀 22d, 两者相对设置。 所述固定刀 22d固定在活动壳架 l id 后端所设矩形空腔内, 其一端固定于矩形空腔内壁, 另一端向外伸出, 固定刀 2 2d刀口 222d为斜面, 刀体上端设有止档轴 221d; 所述移动刀 21d设于活动壳架 11 d后端内腔内, 其位置与固定刀 22d相对应, 其刀体上设有轴 211d, 藉此轴连接 于伸缩杆 212d, 而刀体可在伸缩杆 212d上摆动, 伸缩杆 212d则穿过活动壳架 l id 上的导弓 I孔 14d露出在外而可做伸缩活动; 所述轴 21 Id上套设有扭转螺旋弹簧 21 3d, 其一端 2131d勾于移动刀上的孔 214d, 另一端 2132d勾于伸缩杆边缘 2121d, 此扭转螺旋弹簧的弹力可使移动刀 21d呈图 13中的倾斜状, 固定于移动刀 21d上 的止档柱 215d则抵住伸缩杆边缘 2121d, 以限制移动刀 21d的倾斜度; 拉力螺旋 弹簧 216d—端连接于伸缩杆 212d, 另一端连接于活动壳架 l ld, 其拉力使移动刀 21d远离固定刀 22d, 而使伸缩杆 212d向活动壳架 l id外伸出。 所述移动刀 21d上 还设有止档轴承 217d, 该止档轴承 217d中间设有凹槽 2171d, 可与固定刀 22d上 止档轴 221d对应配合。 当推动活动壳架 l id绕轴 1221d逆吋针方向旋转吋, 伸缩 杆 212d压向墙壁而向左缩入活动壳架 l id内, 设于其上的移动刀 21d亦向左移动 , 移动刀刀口 218d右边 2181d先与固定刀刀口 222d右边 2221d夹合 (参见图 13) , 接着止档轴承 217d上的凹槽 2171d套住止档轴 221d, 伸缩杆 212d继续向活动壳 架 l id腔内移动吋, 移动刀 21d即以止档轴 221d为转动中心 (在图 13中的) 顺吋 针方向旋转, 于是二刀口的夹合点就如同剪刀一般从左边向右边做渐进性移动 , 穿越两刀口的纸就被剪断。
[155] 同前述实施例, 本实施例裁纸机构 2d之裁刀及配合件也可为其它结构, 如: 所 述弧面刀刃口可为直线或弧线, 配合件可以是含有刃口的固定刀, 也可为非刃 口其它构件构件, 其结构设计可在第一壳架 12c及第二壳架 10c相对运动吋, 所述 弧面刀与配合件对应配合, 形成交错裁切或抵顶裁切方式, 同样可以实现切断 纸带的功能。
[156] 本实施例纸的支持及纸带推送支持机构 3d设置于活动壳架 l id纸卷活动槽 115d 后端, 其包括纸带导引件 32d, 所述纸带导引件 32d下端固定在活动壳架 l id纸卷 活动槽 115d底部, 上端有一半圆状曲面, 从活动壳架 l id内腔伸出, 垫于拉出的 纸带 R1下面, 令其弯曲而进入裁纸机构 2d (纸带导引件 32d也可与活动壳架 l id 整体制作, 在活动壳架 l id后端向外延伸一半圆状曲面) 。
[157] 与实施例三同样地, 所述纸带导引件 32d顶部亦可横向设计成多个凹凸起伏的 波浪状, 可作为纸带的强固机构, 使置于该纸带导引件 32d顶部的纸带 R1亦形成 波浪状, 以提高纸头 R2的刚性。
[158] 在纸卷 R与纸带导引件 32d之间, 还设有纸带支持件 31d, 其柔软而有弹性, 下 端 311d固定于活动壳架 l id内的支持板槽 113d下端, 上端 312d为半圆状, 有一弧 面 (也可用装设在支持板上端的细辊柱取代此弧面) 顶触从纸卷拉出的纸, 可 让纸顺利的在上面滑过; 从纸卷 R拉出的纸带 R1经过支持板 3 Id上端的弧面 312d 而被支承, 可保持不垂落而便于被推送。 如图 15a、 15b所示, 所述纸带支持件 31 d顶部亦横向设计成多个凹凸起伏的波浪状, 使置于该纸带支持件 3 Id顶部的纸 带 R1亦形成波浪状, 可提高纸头 R2的刚性, 避免其在输送过程中垂落。
[159] 纸卷 R放置在壳架 l id中的纸卷活动槽 115d中, 此活动槽足够大, 而可让纸卷 R 做适当的滚动。 另外为了使输出的纸不偏左也不偏右, 有二导正块 34d以连接杆 341d连接于壳架 Id内部, 此二导正块 34d有适当的弧面, 经过的纸若偏左或偏右 , 纸的边缘碰到导正块 34d即可令纸滑向中央。 [160] 以上所述实施例仅表达了本发明几种实施方式, 其描述较为具体和详细, 但并 不能因此而理解为对本发明专利范围的限制。 应当指出的是, 对于本领域的普 通技术人员来说, 在不脱离本发明构思的前提下, 还可以做出各种变形、 修改 和应用, 在本案的一个实施例中的许多机构、 构造, 若加以适当的变形、 修改 、 应用, 往往能用于另一个实施例。
[161] 如, 上述各实施例中, 所述的各壳架其造型均可为壳片或壳体状, 也可为支架 状, 并不限于叙述及实施例图中描绘的形状, 例如实施例一、 二中的第一壳架 、 第二壳架均可将其中间平面和弧面的部份挖空、 除去, 只剩各边缘、 棱线、 棱角, 如此即呈支架状; 而实施例三中的第一壳架, 若将其左右二侧板 123c向后 延伸至其固定的墙面, 则此壳架呈向上包起的凹状壳体; 实施例四中的固定壳 架 12d若将其上平面加宽, 并加设 (向下的) 二侧板, 则此壳架可呈向下包盖的 壳片状。
[162] 如实施例一的纸带的输送构造 (包括所述第一支持架 31、 第二支持架 32及各所 属构件) 可应用于实施例二, 概要为将实施例二的推送架 31b及其相关构造、 支 爪 24b取消, 而将实施例一的纸带的输送构造由向上转向为横向, 置入实施例二 的壳架中, 将活动臂 312、 322适当的修改而分别连接于第二壳架和第一壳架适 当处, 加上一些适当的变形就可达成。
[163] 再者, 若将实施例一由竖立改为横躺, 取消驱动壳架构造, 并加以适当的变形 、 修改, 即可如同实施例二一般操作、 出纸、 使用。
[164] 又如, 实施例四的裁纸机构可应用于实施例三, 如活动座的移动是平直的直线 冲向纸带, 移动刀 21d移向固定刀 22d, 唯活动座其驱动构造改为实施例四的伸 缩杆 212d状, 而改变方向为水平向左穿出壳架, 至于导弓 I孔 14d、 轴 211d、 扭转 螺旋弹簧213(1、 孔214(1、 止档柱 215d、 拉力螺旋弹簧 216d、 固定刀 22d、 止档轴 承 217d、 凹槽 2171d、 止档轴 221d等构造仍参照实施例四同样设有, 唯需改变方 向, 而向左穿出壳架的伸缩杆, 其左端杆端连接类同实施例一的便于人力推压 的驱动面 131, 唯驱动面改为竖直方向, 并取消驱动面上的出纸口。 同样可以实 现其裁纸功能。
[165] 若再做一些修改、 应用, 实施例四的裁刀构造也可取代实施例一、 实施例二的 裁刀构造, 例如将实施例四的固定刀 22d及其相关构造固定在实施例一、 实施例 二中第一壳架, 将伸缩杆 212d修改为固定座, 用以固定在实施例一、 实施例二 中第二壳架, 原设置于伸缩杆 212d的移动刀 21d及其相关构造仍作适当的保留并 修改, 如此即为移动刀 21d设置于实施例一、 实施例二中第二壳架。
[166] 另外, 本案的裁纸机构及其部件、 纸带推送支持机构及其部件, 均可加以变形 、 修饰而用于各实施例, 或替换各实施例的相应部件。
[167] 另外, 本案的各实施例均为依据本案基本的、 主要的方法 (包括藉推压壳架而 驱动裁纸机构、 利用倾斜动作使纸卷滚动或移动藉以拉出纸带、 将纸带横断面 曲折成反复曲折状以增加纸带在输送方向上的刚性、 在纸带输送方向上反复曲 折而暂存一些纸量) 加以应用且釆纳适当的机构、 构造而描述, 然而适当的机 构、 构造繁多, 未及一一叙述, 因此, 凡属于本发明精神范畴者, 均为本发明 的范围。
