Description

紧固装置 技术领域
本发明是有关于一种紧固装置，且尤其是有关一种能收放系线的紧固装置。
背景技术
在日常生活中，常使用绳子及系带等线体来收束物品，最常见的收束手段是利用线体来回穿梭于物品上的孔洞，再以绳结固定，例如绑绳鞋类等。但是此种收束手段容易因为外力因素而导致绳结松脱，不仅必须重绑绳结，也因为无法稳固的收束物品而带来许多的不便。
为了解决此类的问题，有业者发展出简易束线机构，其包含一壳体，一掣动单元及一弹簧，壳体上具有穿孔供线体通过，其透过弹簧与掣动单元之间的作用力使线体被夹在掣动单元及壳体之间而达到紧固效果，按压弹簧改变掣动单元位置即可拉动改变线体长度。但，此种束线机构是透过弹簧的复位力来提供紧固力，仍然容易因为振动或外力因素而使线体松脱，且此种束线机构并无空间容纳线体，因此线体外露也容易造成危险。
是以又有业者发展出另一种可旋转收束并固定系带的扣具，其线体可容置在扣具内部，且透过内部构件的机械力干涉使得线体长度可以被调整，同时调整收束的紧度。然而，此种扣具的结构复杂，使得制造成本提升，同时具有组装及维修困难的问题。
因此，不断有业者针对扣具内部的结构进行调整及改良，皆希望可以在结构简化的前提下，仍保有扣具的紧固能力，并增加结构可靠度以避免寿命减短。
有鉴于此，如何有效改善扣具等紧固装置的结构，遂成相关业者努力的目标。

请参阅图1、图2、图3、图4及图5，其中图1绘示依照本发明一第1实施例的一种紧固装置100的立体示意图，图2绘示图1的紧固装置100的一爆炸示意图，图3绘示图1的紧固装置100的另一爆炸示意图，图4绘示图1的紧固装置100的一剖视示意图，图5绘示图1的紧固装置100的另一剖视示意图。紧固装置100包含一外壳单元200、一线盘300、一掣动单元400、一旋钮500及一连接单元600。
外壳单元200具有一径向(未绘示)及一轴向I1且包含一环壁220，环壁220围绕一内部空间240。线盘300位于内部空间240且包含一轴心空间340，轴心空间340包含一大径段342及一小径段341，小径段341沿轴向I1连接于大径段342；掣动单元400沿轴向I1设置于线盘300的上方，掣动单元400选择性地阻挡线盘300朝一释放方向A1转动；旋钮500沿轴向I1设置于掣动单元400的上方，且旋钮500耦合于掣动单元400。连接单元600连接旋钮500，且连接单元600穿设于轴心空间340并受大径段342限位。
借此，透过让线盘300的轴心空间340具有大径段342及小径段341，而能使连接单元600被限位于大径段342，以避免外壳单元200、线盘300、掣动单元400及旋钮500在转动过程中松脱分离，能有助于增加结构可靠度。后面将详述紧固装置100的细部结构。
外壳单元200可还包含一止挡部250，止挡部250位于环壁220且沿径向朝内部空间240凸出，线盘300位于止挡部250下方。外壳单元200还包含一底座210、多个咬合齿230及一内环凹260，底座210供环壁220设置，且环壁220可以是以卡合的方式设置于底座210。多个咬合齿230位于环壁220且朝向内部空间240，咬合齿230位于环壁220的一上端，内环凹260凹设于环壁220的一下端，止挡部250则具有凸环结构且邻近咬合齿230。换句话说，透过环壁220的内径变化可以形成内环凹260及止挡部250。
线盘300包含一中空轴柱380、上环部360及下环部370，上环部360及下环部370分别由中空轴柱380沿径向朝外凸出，且上环部360沿轴向I1位于下环部370的上方，因此上环部360与下环部370之间可形成一环状轨道310，环状轨道310可供一系线(未绘示)卷绕。线盘300可还包含多个嵌合齿320沿轴向I1位于上环部360的上方，且中空轴柱380的一内周面350环绕形成轴心空间340，透过中空轴柱380的内径变化可形成彼此相连通的大径段342及小径段341，大径段342位于小径段341的下方。中空轴柱380的内周面350可包含一外扩区351及一直面区352，外扩区351及直面区352均位于大径段342，线盘300可还包含一下开口330连通轴心空间340。
掣动单元400包含一环状本体440、一第一保持部410、一第二保持部420、三导引部430、三棘臂450、三卡部460、多个嵌卡齿470、一中心孔480及二 凸块491、492。中心孔480位于环状本体440中央，导引部430为自环状本体440朝外突伸的斜齿结构且用以与旋钮500耦合。第一保持部410及第二保持部420自环状本体440向内突出，且第一保持部410及第二保持部420各自包含一自由端411、421，自由端411、421受力后可沿径向移动，外力解除后即可复位。二凸块491、492自环状本体440向内突出，且二凸块491、492与二自由端411、421之间具有间隔。棘臂450包含一远端452及一近端451，近端451连接环状本体440的外面，远端452则用来与咬合齿230可分离地啮合。三个卡部460则分别位于三个棘臂450上。嵌卡齿470位于环状本体440的下方，而能与线盘300的嵌合齿320可选择地啮合。
旋钮500包含一导引轨道510、一凸柱520、一通孔530及二定位块540，导引轨道510设于旋钮500的一内壁，凸柱520沿轴向I1朝内部空间240凸出，通孔530贯穿凸柱520，二定位块540则沿径向对称设罝于凸柱520的外侧。在此要特别说明的是，图3因为视角因素仅能看到一定位块540，然阅读者可知，在视角看不到的一侧，还有另一定位块540。
连接单元600包含一第一部件组(未标示)及一第二部件组(未标示)，第一部件组连接旋钮500，第二部件组穿设于轴心空间340以连接第一部件组，且第二部件组受大径段342限位。在第1实施例中，连接单元600的第一部件组包含一螺杆610，第二部件组包含一连接套筒620，连接套筒620包含一顶部622及一筒部621，筒部621连接顶部622，筒部621穿过小径段341且供螺杆610锁接，顶部622被限位于大径段342。
更仔细地说，当线盘300由环壁220的下方放入于内部空间240后，如图4所示，上环部360及下环部370分别被止挡部250及内环凹260限位，而使得线盘300无法由环壁220的上方脱离。导引部430(见图3)耦合于导引轨道510，以连接旋钮500与掣动单元400，旋钮500的凸柱520则凸入掣动单元400的中心孔480(见图2)。
连接套筒620可由线盘300的下开口330(见图3)由下往上置入轴心空间340，由于小径段341、大径段342、顶部622及筒部621的直径关系，使得筒部621可穿过小径段341，顶部622则被留于大径段342。此时，只要将螺杆610锁入筒部621，即可使旋钮500及掣动单元400与线盘300组合。且由于 止挡部250的关系，在螺杆610锁入筒部621后，旋钮500、掣动单元400、线盘300及环壁220即无法分离，而可完成组装。在其他实施例中，亦可以不设置止挡部，而是让咬合齿朝向内部空间凸出，以阻止线盘自环壁上方脱离；或是止挡部及内环凹择一设置于环壁，不以上述揭露为限。
较佳地，筒部621可与凸柱520嵌合，以使连接套筒620与旋钮500同动。其中，筒部621的外壁形状可与通孔530的内壁配合，而能使筒部621嵌合于凸柱520，较佳地，筒部621的外壁截面及通孔530的内壁截面均呈非圆形。由于拉动系线使线盘300朝释放方向A1转动时，线盘300可能会摩擦第二部件组，若第二部件组的筒部621与凸柱520嵌合，能有助于防止第二部件组受摩擦影响产生旋转，进而避免其与第一部件组之间的锁固分离。
如图4所示，掣动单元400位于第一位置，掣动单元400的嵌卡齿470与线盘300的嵌合齿320啮合，且棘臂450的远端452(见图2)于释放方向A1(见图2)上啮合于咬合齿230，棘臂450的远端452于一束紧方向A2(见图2)上不断地与咬合齿230分离，而卡部460则因位置相对低于咬合齿230，无与咬合齿230啮合。因此，朝束紧方向A2转动旋钮500，可带动掣动单元400连动线盘300收线，且旋钮500无作动时，棘臂450的远端452抵顶于咬合齿230以防止线盘300朝释放方向A1转动，而能防止系线被释放。
又，旋钮500朝一释放方向A1转动可带动掣动单元400沿轴向I1上升，以使掣动单元400与线盘300分离。更仔细地说，掣动单元400位于第一位置时，导引部430与旋钮500的导引轨道510啮合，其中一定位块540位于第一保持部410的自由端411与凸块491之间，另一定位块540位于第二保持部420的自由端421与凸块492之间。当旋钮500朝释放方向A1转动时，掣动单元400受限于棘臂450与咬合齿230的啮合关系而无法一同转动，因此二定位块540分别压抵于二自由端411、421，二自由端411、421沿径向变形而使得旋钮500可相对掣动单元400转动，导引部430则受导引轨道510导引，可相对导引轨道510沿轴向I1往上升，以切换掣动单元400位于第二位置。此时，前述其中一定位块540改位于第一保持部410的自由端411与凸块492之间，前述另一定位块540改位于第二保持部420的自由端421与凸块491之间。
因此，如图5所示，由于掣动单元400位于第二位置，掣动单元400的嵌卡齿470与线盘300的嵌合齿320分离，此时线盘300不受掣动单元400影响，而能朝释放方向A1转动，拉动系线即可放线。
请参阅图6及图7，其中图6绘示依照本发明一第2实施例的一种紧固装置100a的立体爆炸示意图，图7绘示图6的紧固装置100a的一剖视示意图。紧固装置100a包含一外壳单元(未标示)、一线盘300a、一掣动单元400a、一旋钮500a及一连接单元600a，外壳单元、线盘300a、掣动单元400a及旋钮500a的结构与关系和第1实施例的外壳单元200、线盘300、掣动单元400及旋钮500类似，但连接单元600a的结构与第1实施例的连接单元600不同。
连接单元600a包含第一部件组与第二部件组620a，第一部件组包含一锁固轴套610a，第二部件组620a包含一止挡环621a及一螺杆622a，止挡环621a限位于大径段(未标示)，螺杆622a穿过止挡环621a及小径段(未标示)锁接于锁固轴套610a。锁固轴套610a包含一下嵌合部611a，止挡环621a包含一内嵌合槽6211a，内嵌合槽6211a与下嵌合部611a嵌合。旋钮500a包含一凸柱(未标示)沿轴向朝内部空间(未标示)凸出，锁固轴套610a还包含一上嵌合部612a连接下嵌合部611a，且上嵌合部612a与凸柱嵌合。
详细地说，止挡环621a还包含一底部6213a及一身部6212a，身部6212a连接底部6213a，且内嵌合槽6211a位于身部6212a。锁固轴套610a的上嵌合部612a形状与位于凸柱内的通孔(未标示)配合，下嵌合部611a的形状与内嵌合槽6211a配合，因此，当锁固轴套610a穿入通孔时，上嵌合部612a与凸柱嵌合，下嵌合部611a则外露于凸柱并凸入小径段内。
此外，如图7所示，止挡环621a的身部6212a进入小径段，内嵌合槽6211a与下嵌合部611a嵌合，底部6213a则留于大径段受大径段限位，而螺杆622a可沿轴向由下往上锁入锁固轴套610a内，以完成旋钮500a、掣动单元400a、线盘300a及环壁220a的组合。由于拉动系线使线盘300a朝释放方向转动时，线盘300a可能会摩擦第二部件组620a，因为第二部件组620a的止挡环621a透过锁固轴套610a与凸柱嵌合，能有助于防止第二部件组620a受摩擦影响产生旋转，进而避免其与第一部件组之间的锁固分离。
请参阅图8及图9，其中图8绘示依照本发明一第3实施例的一种紧固装 置100b的立体爆炸示意图，图9绘示图8的紧固装置100b的一剖视示意图。紧固装置100b包含一外壳单元(未标示)、一线盘300b、一掣动单元400b、一旋钮500b及一连接单元600b，外壳单元、线盘300b、掣动单元400b及旋钮500b的结构与关系和图6第2实施例的外壳单元、线盘300a、掣动单元400a及旋钮500a类似，但连接单元600b的结构与第2实施例的连接单元600a不同。
更仔细地说，连接单元600b的第一部件组包含一锁固轴套610b，第二部件组620b包含一止挡环621b及一螺杆622b，锁固轴套610b的结构可与第2实施例的锁固轴套610a相同，但其亦可以不包含下嵌合部，而是加长上嵌合部沿轴向的长度，使其凸入小径段中，包含但不以上述揭露为限。在第3实施例中，止挡环621b具有一环状结构，锁固轴套610b包含一下端面611b，螺杆622b锁入锁固轴套610b后，可使止挡环621b抵顶下端面611b，以完成旋钮500b、掣动单元400b、线盘300b及环壁220b的组装。由于拉动系线使线盘300b朝释放方向转动时，线盘300b可能会摩擦第二部件组620b，因为止挡环621b受螺杆622b的迫紧抵顶于下端面611b，止挡环621b、螺杆622b与下端面611b之间的摩擦力大于线盘300b摩擦止挡环621b的摩擦力，能有助于防止第二部件组620b受摩擦影响产生旋转，进而避免其与第一部件组之间的锁固分离。
请参阅图10及图11，其中图10绘示依照本发明一第4实施例的一种紧固装置100c的立体爆炸示意图，图11绘示图10的紧固装置100c的一剖视示意图。
紧固装置100c包含一外壳单元(未绘示)、一线盘300c、一掣动单元400c、一旋钮500c及一连接单元600c，外壳单元、线盘300c、掣动单元400c及旋钮500c的结构与关系和第3实施例的外壳单元、线盘300b、掣动单元400b及旋钮500b类似，但连接单元600c的结构与第3实施例的连接单元600b不同。
更仔细地说，连接单元600c的第一部件组包含一锁固轴套610c，第二部件组包含一螺杆620c，螺杆620c包含一头部622c及一杆部621c，杆部621c连接头部622c，杆部621c穿设于轴心空间以锁接于锁固轴套610c，头部622c 被大径段限位。在结构配置上，可让头部622c的直径大于小径段的直径，及让螺杆620c的直径小于大径段直径，而能让螺杆620c限位于大径段，以完成旋钮500c、掣动单元400c、线盘300c及环壁220c的组装。由于拉动系线使线盘300c朝释放方向转动时，线盘300c可能会摩擦第二部件组，可在锁紧螺杆620c时即加强螺杆620c与锁固轴套610c之间的锁固力，例如可采用加宽螺牙、点胶等方式，使螺杆620c与锁固轴套610c之间的锁固力大于线盘300c摩擦螺杆620c的摩擦力，能有助于防止第二部件组受摩擦影响产生旋转，进而避免其与第一部件组之间的锁固分离。
在其他的实施例中，连接单元亦可以呈凸柱结构，其可以是一体连接于旋钮且朝轴心空间凸入，或是利用胶合方式固定于旋钮。连接单元可包含一下凸缘，透过连接单元的上端连接于旋钮以及下凸缘限位于大径段的方式，可完成旋钮、掣动单元、线盘及环壁的组装。
虽然本发明已以实施例揭露如上，然其并非用以限定本发明，任何熟悉此技艺者，在不脱离本发明的精神和范围内，当可作各种的更动与润饰，因此本发明的保护范围当视所附的权利要求书所界定的范围为准。
