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，也因为无法稳固地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线体改变长度。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及图4，其中图1绘示依照本发明第1实施例的一种紧固装置100d的立体示意图，图2绘示图1第1实施例的紧固装置100d的一爆炸示意图，图3绘示图1第1实施例的紧固装置100d的另一爆炸示意图，图4绘示图1第1实施例的紧固装置100d的剖视示意图。紧固装置100d包含一外壳单元200d、一线盘300d、一掣动单元400d、一旋钮500d以及一连接单元600d。
外壳单元200d包含一环壁220d、一上开口(未标示)、一下开口(未标示)及一底座210d，环壁220d围绕一内部空间240d，上开口连通内部空间240d，下开口相反于上开口且连通内部空间240d，底座210d可拆地直接连接环壁220d；线盘300d位于内部空间240d；掣动单元400d位于内部空间240d且选择性地阻挡线盘300d朝一释放方向A1(仅标示于图2，其余附图中未标示)转动；连接单元600d连接旋钮500d、线盘300d及掣动单元400d中至少一者。其中，旋钮500d、连接单元600d、掣动单元400d及线盘300d中至少一者限位于环壁220d，以使环壁220d、线盘300d、掣动单元400d及旋钮500d组接为一体，且连接单元600d未直接穿过或直接连接底座210d。
借此，透过结构配置，紧固装置100d具有容易拆组的优点，后面将详述紧固装置100d的细部结构。
外壳单元200d可还包含第一内环凹槽270d、第二内环凹槽260d及多个咬合齿230d，第一内环凹槽270d位于环壁220d的一下端，第二内环凹槽260d位于环壁220d且位于第一内环凹槽270d的上方，咬合齿230d位于环壁220d的一上端且面向内部空间240d。在直径的大小排序上，二相对的咬合齿230d 的尖端连线小于环壁220d的内部直径，环壁220d的内部直径小于第二内环凹槽260d的直径，且第二内环凹槽260d的直径小于第一内环凹槽270d的直径。
线盘300d可包含一上环部360d、一下环部370d及一轴心空间340d，当线盘300d由环壁220d的下开口往上置入内部空间240d时，线盘300d的上环部360d会位于咬合齿230d的下方，且下环部370d会容设于第二内环凹槽260d。
连接单元600d可包含一底盘621d，底盘621d可容设于第一内环凹槽270d。仔细而言，连接单元600d可还包含一螺杆610d以及一连接杆622d，螺杆610d连接旋钮500d，连接杆622d自底盘621d朝上凸出以插入线盘300d的轴心空间340d，连接杆622d并连接于螺杆610d。
如图2至图4所示，底盘621d及连接杆622d是一体连接为一件式构件，底盘621d位于线盘300d的下方以使连接杆622d凸入轴心空间340d，而螺杆610d可由上而下锁入连接杆622d的中心通道并限位于旋钮500d。底盘621d的直径大于下环部370d的直径，而由于底盘621d是容设于第一内环凹槽270d且被环壁220d限位，故当螺杆610d自旋钮500d锁入连接杆622d后，环壁220d、线盘300d、掣动单元400d及旋钮500d即可组接为一体，换句话说，环壁220d、线盘300d、掣动单元400d及旋钮500d无法彼此脱离。
掣动单元400d可包含一环状本体440d、三导引部430d、三棘臂450d及一中心孔480d。中心孔480d位于环状本体440d的中央，导引部430d为自环状本体440d朝外突伸的斜齿结构且用以与旋钮500d耦合，而棘臂450d则与咬合齿230d可分离地啮合。
旋钮500d包含一导引轨道510d、一凸座520d及一通孔530d，导引轨道510d设于旋钮500d的一内壁且用以与导引部430d耦合，凸座520d沿轴向朝内部空间240d凸出，通孔530d贯穿凸座520d，连接杆622d可进入通孔530d内，再锁接螺杆610d。
如图4所示，此时掣动单元400d位于第一位置，掣动单元400d的嵌卡齿470d与线盘300d的嵌合齿320d啮合，因此，朝束紧方向A2(仅标示于图2，其余附图中未标示)转动旋钮500d，可带动掣动单元400d连动线盘300d收线，且旋钮500d无作动时，棘臂450d抵顶于咬合齿230d以防止线盘300d朝释放方向A1转动，而能防止系线被释放。又，旋钮500d朝释放方向A1转动可带动掣动单元400d沿轴向上升改位于第二位置，以使掣动单元400d与线盘300d 分离，此时掣动单元400d的嵌卡齿470d与线盘300d的嵌合齿320d分离，线盘300d不受掣动单元400d影响，而能朝释放方向A1转动，拉动系线即可放线。
请参阅图5及图6，其中图5绘示依照本发明第2实施例的一种紧固装置100e的爆炸示意图，图6绘示图5第2实施例的紧固装置100e的剖视示意图。紧固装置100e包含一外壳单元(未于图5及图6中标示)、一线盘300e、一掣动单元400e、一旋钮500e以及一连接单元600e。连接单元600e可还包含一凸柱610e以及一螺杆623e，凸柱610e直接自旋钮500e的一内顶面朝下凸入线盘300e的一轴心空间(未于图5及图6中标示)，螺杆623e将底盘621e锁接于凸柱610e。
仔细而言，凸柱610e自旋钮500e的内顶面一体凸出，即，成型旋钮500e时便一并形成凸柱610e，而凸柱610e的长度够长而可直接穿过线盘300e的轴心空间并接触到底盘621e。因此，当螺杆623e穿入底盘621e的孔洞并锁入凸柱610e且螺杆623e的头部限位于底盘621e后，底盘621e可抵贴于凸柱610e的一端面。
请参阅图7及图8，其中图7绘示依照本发明第3实施例的一种紧固装置100f的爆炸示意图，图8绘示图7第3实施例的紧固装置100f的剖视示意图。紧固装置100f包含一外壳单元(未于图7及图8中标示)、一线盘300f、一掣动单元400f、一旋钮500f以及一连接单元600f。连接单元600f可包含一螺杆610f、一底盘621f以及一塞柱624f，螺杆610f连接旋钮500f且限位于掣动单元400f，塞柱624f自底盘621f朝上凸出以插入线盘300f的一轴心空间(未于图7及图8中标示)，且塞柱624f耦合于掣动单元400f。
螺杆610f可自掣动单元400f的中心孔(未于图7及图8中标示)朝上穿入旋钮500f的凸座520f，而螺杆610f的一头部可限位于掣动单元400f。掣动单元400f可包含二夹臂490f耦合于塞柱624f，故当旋钮500f被往上拉时，掣动单元400f可升起并受塞柱624f定位。

请参阅图12及图13，其中图12绘示依照本发明第5实施例的一种紧固装置100h的爆炸示意图，图13绘示图12第5实施例的紧固装置100h的剖视示意图。紧固装置100h包含一外壳单元(未于图12及图13中标示)、一线盘300h、一掣动单元400h、一旋钮500h以及一连接单元600h。连接单元600h可包含一底盘621h、一螺杆623h以及一塞柱624h，塞柱624h自底盘621h朝上凸入掣动单元400h的中心孔(未于图12及图13中标示)，且掣动单元400h的三夹臂490h耦合于塞柱624h。螺杆623h穿过底盘621h及塞柱624h朝上插入以锁接于旋钮500h的凸座520h，且螺杆623h的一头部被底盘621h限位。旋钮500h可包含一下凸环位于凸座520h的下方，且下凸环限位于掣动单元400h。当旋钮500h被往上拉时，掣动单元400h可升起且旋钮500h受塞柱624h定位。
请参阅图14及图15，其中，图14绘示依照本发明第6实施例的一种紧固装置100j的爆炸示意图，图15绘示图14第6实施例的紧固装置100j的剖视示意图。紧固装置100j包含一外壳单元(未于图14及图15中标示)、一线盘300j、一掣动单元400j、一旋钮500j以及一连接单元600j。连接单元600j可包含一螺杆610j、一底盘621j、一塞柱624j以及三夹块626j。三夹块626j自底盘621j朝上凸出，塞柱624j朝上插入底盘621j以与夹块626j耦合，且塞柱624j的一上端面抵贴于掣动单元400j。螺杆610j穿过旋钮500j朝下锁接于塞柱624j，而掣动单元400j被限位于旋钮500j与塞柱624j之间。当旋钮500j被往上拉时，塞柱624j可被夹块626j定位。
请参阅图16及图17，其中图16绘示依照本发明第7实施例的一种紧固装置100k的爆炸示意图，图17绘示图16第7实施例的紧固装置100k的剖视示意图。紧固装置100k与紧固装置100j类似，但塞柱624k是穿入旋钮500k的凸座520k，且塞柱624k的一凸架抵顶于掣动单元400k。
请参阅图18、图19及图20，其中图18绘示依照本发明第8实施例的一 种紧固装置100m的一爆炸示意图，图19绘示图18第8实施例的紧固装置100m的另一爆炸示意图，图20绘示图18第8实施例的紧固装置100m的剖视示意图。紧固装置100m包含一外壳单元(未于图18至图20中标示)、一线盘300m、一掣动单元400m、一旋钮500m以及一连接单元600m。
连接单元600m包含一锁固轴套610m、一止挡环621m以及一螺杆622m。掣动单元400m包含一中心孔480m，且中心孔480m被塑形成与锁固轴套610m的头部对应。锁固轴套610m朝下插入线盘300m的轴心空间(未于图18至图20中标示)，且螺杆622m穿过止挡环621m以锁入锁固轴套610m，使止挡环621m被夹抵于锁固轴套610m的端面与螺杆622m的头部之间。
线盘300m可包含嵌合齿320m，各嵌合齿320m包含一坡段。掣动单元400m可还包含三棘臂450m、三限制块420m及三内缩槽410m。各棘臂450m对应各限制块420m且位于限制块420m的下方，且各内缩槽410m邻近各限制块420m。其中，当掣动单元400m受系线的一拉力拉往释放方向时，各棘臂450m弯曲以允许各棘臂450m的远端抵顶于各限制块420m，借此防止棘臂450m的过度弯曲。
如图18至图20所示，旋钮500m可包含三卡臂530m，掣动单元400m可包含三卡凸460m，各卡臂530m与各卡凸460m嵌合。旋钮500m可还包含三定位凸550m分别插入掣动单元400m的三定位孔470m，以使掣动单元400m与旋钮500m耦合。掣动单元400m包含三夹臂490m，线盘300m包含一定位环390m对应三夹臂490m，当旋钮500m被往上拉时，掣动单元400m沿一轴向定位于一上升位置，三夹臂490m从定位环390m的下侧移至上侧，而能定位掣动单元400m，且掣动单元400m位于上升位置时与设置在环壁220m上的咬合齿230m分离。
环壁220m可包含三刻槽261m位于环壁220m的上方表面。各刻槽261m可邻近部分的咬合齿230m，而此些邻近刻槽261m的咬合齿230m均有部分被切除以形成一上斜面。旋钮500m被下压会使掣动单元400m定位于一下降位置，并让棘臂450m再度与咬合齿230m啮合，而当掣动单元400m由上升位置朝下降位置移动时，棘臂450m会径向朝内偏摆并进入内缩槽410m，再被刻槽261m及咬合齿230m的上斜面导引而能顺畅地与咬合齿230m再度啮合。各限制块420m可包含一倾斜面421m，倾斜面421m亦有助于让棘臂450m与 咬合齿230m顺畅地啮合。
请参阅图21、图22及图23，其中图21绘示依照本发明第9实施例的一种紧固装置100n的爆炸示意图，图22绘示图21第9实施例的紧固装置100n的剖视示意图，图23绘示图22第9实施例的紧固装置100n沿割面线23-23的剖视示意图。紧固装置100n包含一外壳单元(未于图21至图23中标示)、一线盘300n、一掣动单元400n、一旋钮500n以及一连接单元600n。掣动单元400n包含一锁固轴套610n、一止挡环621n以及一螺杆622n。紧固装置100n与紧固装置100m类似，但外壳单元的环壁220n包含一无齿上部221n，且无齿上部221n与掣动单元400n之间的一间隙是用来容置三卡臂530n。旋钮500n可还包含多个抵贴部540n，抵贴部540n与旋钮500n的内壁之间形成一上环凹槽，而无齿上部221n可插入上环凹槽内。此外，抵贴部540n可被塑形成与掣动单元400n对应，然本发明不以此为限。透过上述的结构配置，紧固装置100n的结构可靠度可被提升。
请参阅图24、图25及图26，图24绘示依照本发明第10实施例的一种紧固装置100p的爆炸示意图，图25绘示图24第10实施例的紧固装置100p的剖视示意图，图26绘示图25第10实施例的紧固装置100p沿割面线26-26的剖视示意图。紧固装置100p包含一外壳单元(未于图24至图26中标示)、一线盘300p、一掣动单元400p、一旋钮500p以及一连接单元600p。掣动单元400p包含一锁固轴套610p、一止挡环621p以及一螺杆622p。紧固装置100p与紧固装置100n类似，外壳单元的环壁220p包含一无齿上部221p，且旋钮500p包含多个抵贴部540p，然抵贴部540p的数量与形状和抵贴部540n不同。

请参阅图31及图32，其中图31绘示依照本发明第13实施例的一种紧固装置100t的爆炸示意图，图32绘示图31第13实施例的紧固装置100t的剖视示意图。紧固装置100t包含一外壳单元(未于图31及图32中标示)、一线盘300t、一掣动单元400t、一旋钮500t、一棘轮环700t以及一连接单元(未于图31及图32中标示)。掣动单元400t可包含一掣动环410t、一内环450t及一螺柱430t。内环450t可动地位于掣动环410t且与线盘300t耦合，螺柱430t耦合于内环450t，而掣动环410t及棘轮环700t位于线盘300t的下方。外壳单元包含底座210t及环壁220t，且底座210t的深度足以容纳棘轮环700t及掣动环410t。连接单元由一螺杆610t组成，螺杆610t插入螺柱430t以锁接于旋钮500t的凸座520t。据此，当旋钮500t朝释放方向被转动时，内环450t受螺柱430t导引上升以与掣动环410t分离。
请参阅图33及图34，其中图33绘示依照本发明第14实施例的一种紧固装置100s的爆炸示意图，图34绘示图33第14实施例的紧固装置100s的剖视示意图。紧固装置100s包含一外壳单元(未于图33及图34中标示)、一线盘 300s、一掣动单元400s、一旋钮500s、一棘轮环700s以及一连接单元(未于图33及图34中标示)。掣动单元400s可包含一螺套450s、一掣动环410s及一螺柱430s。螺套450s与掣动环410s一体成形且自掣动环410s朝上凸入线盘300s的轴心空间(未于图33及图34中标示)。螺柱430s耦合于螺套450s。连接单元由一螺杆610s组成，螺杆610s插入螺柱430s以锁接于旋钮500s的凸座520s。据此，当旋钮500s朝释放方向被转动时，螺套450s受螺柱430s导引下降，以使掣动环410s与线盘300s分离。
请参阅图35及图36，其中图35绘示依照本发明第15实施例的一种紧固装置的一旋钮500u的立体示意图，图36绘示图35第15实施例的紧固装置的一掣动单元400u的立体示意图。第15实施例的紧固装置与图18至图20的紧固装置100m类似，旋钮500u可包含三卡臂530u与掣动单元400u的三卡凸460u嵌合。旋钮500u可还包含三定位凸550u插入掣动单元400u的三定位孔470u。此外，旋钮500u可还包含三径向凸指560u，掣动单元400u可包含三径向开槽480u，各径向凸指560u与各径向开槽480u嵌合。据此，掣动单元400u可与旋钮500u耦合，且旋钮500u的转动力可更有效地传至掣动单元400u。
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。
