Abstract

本实用新型是揭露一种健身器，其包含一第一支架、一第二支架、一凸部、一线性弹性件以及一连杆。第二支架与凸部同轴枢接于第一支架，凸部摆动连结第二支架，连杆连动线性弹性件，线性弹性件可摆动地位移伸缩并限位在第一支架内。在第二支架相对第一支架枢摆时，由于连杆为刚性结构，连杆可限制线性弹性件的弹动范围，使线性弹性件能稳定地伸缩，并可防止线性弹性件触碰到第一支架的内壁。因此，使用连杆可以避免线性弹性件因触碰而造成的声响与元件磨损，达到无噪音且延长元件寿命之效。

Description

健身器
技术领域
本实用新型是关于一种健身器，特别是关于一种采用刚性连杆结构的健身器。
背景技术
一般多功能型的健身器具有往复夹合式支架，利用支架的夹合来辅助仰卧起坐、伏地挺身、健腹等运动，达到以单一器械辅助多种运动的功效。
传统的往复夹合式健身器的复位件是采用扭力弹簧或是线性弹性件，然而扭力弹簧的力量往往过大，不适合需要较小复位力的使用者，且扭力弹簧易疲劳形变。此外，当需要调节复位力时，就需更换不同复位力的扭力弹簧，使用及更换操作麻烦不便，也不适合有众多不同力量需求的使用者群。因此，习用产品的使用者难以自行调节扭力弹簧的扭力，也造成以往习用技术的使用效果受限。
另外，当复位件采用线性弹性件时，如同中国台湾专利第M462133号，其说明书内容揭露健身器是透过缆索直接或间接地连结带动线性弹性件，使健身器在往复枢摆时具有适当的复位力。使用者可透过缆索自行调整线性弹性件的复位力，达到客制化的需求。然而，传统缆索均为软性结构，在连结带动线性弹性件的过程中，不仅需要较多的导引结构及设计来导引缆索，而且缆索无法有效且快速地限制线性弹性件的位移或摆动，容易造成线性弹性件在伸缩时因弹动过大而触碰到健身器的其他元件，进而产生碰撞的声响以及元件磨损的问题，此问题会降低使用者的舒适感、购买意愿以及缩短健身器的元件寿命。
实用新型内容
因此，本实用新型提供一种健身器，利用刚性结构的连杆取代传统软性的缆索，以配合线性弹性件实现往复夹合的操作。此连杆能使线性弹性件限位于第一支架内，且此刚性连杆限制了线性弹性件的弹动范围，可防止线性弹性件触碰撞击到周边其他构件。因此，使用刚性连杆可以避免线性弹性件因触碰撞击造成的声响与元件磨损，达到作动稳定、无噪音且延长元件寿命的功效。
本实用新型的一实施方式为一种健身器，其包含一第一支架、一第二支架、一凸部、一线性弹性件以及一连杆。其中线性弹性件包含一第一端与一第二端，且第二端包含一容置空间，连杆则由一连接端、一杆身及一施力端所组成。其中第二支架枢接于第一支架。凸部摆动连结第二支架，且凸部与第二支架同轴枢接于第一支架。线性弹性件伸缩弹动于第一支架上，第一端设于第一支架，而容置空间则向外开设一开孔。此外，连接端被开孔限位于容置空间中，杆身可摆动地伸缩于开孔内，施力端则枢接于凸部。
借此，本实用新型的健身器利用刚性结构的连杆使线性弹性件限位于第一支架内。由于连杆的连接端限位在线性弹性件的第二端的容置空间中，因此，刚性连杆可快速地限制线性弹性件的位移、摆动及弹动范围，使线性弹性件能稳定地伸缩。
依据前述实施方式的其他实施例如下：前述健身器的连杆的连接端可以为一圆球体。凸部可以包含一抵靠端与一固定端，其中施力端枢接于固定端，而抵靠端则用以抵靠第一支架的内壁。前述健身器可以包含一滑轮，此滑轮与第二支架及凸部均同轴枢设于第一支架。再者，前述健身器可以包含一坐垫，坐垫设于第一支架。此外，第二支架可以包含一靠垫，靠垫是用以承靠使用者的身体。
本实用新型的另一实施方式为一种健身器，其包含一第一支架、一第二支架、一凸部、一线性弹性件、一连杆以及一调整模块。其中线性弹性件包含一第一端与一第二端，第二端包含一容置空间，而连杆由一连接端、一杆身及一施力端所组成，调整模块则包含一锁接件、一螺锁件及一螺配件。其中第二支架枢接于第一支架。凸部与第二支架为一体连结，且凸部与第二支架同轴枢接于第一支架。线性弹性件伸缩弹动于第一支架上，第一端设于第一支架，容置空间向外开设一开孔。再者，连杆的连接端被开孔限位于容置空间中，杆身可摆动地在开孔内伸缩，施力端则枢接于凸部。此外，调整模块可位移地定位第一端，其中锁接件的两端分别锁接第一端与螺锁件的一端，螺锁件的另一端则与螺配件螺锁，且螺配件定位于第一支架上。
借此，本实用新型的健身器使用刚性连杆，配合线性弹性件的特殊连结设计，可以大幅缩小线性弹性件的无效弹动范围，避免线性弹性件因触碰第一支架内壁而造成的声响与元件磨损，达到稳定运作、无噪音且延长元件寿命的功效。此外，凸部与第二支架为一体连结，可降低健身器的制造成本。
依据前述实施方式的其他实施例如下：前述健身器的连杆的连接端可以为一圆球体。凸部可以包含一抵靠端与一固定端，施力端枢接于固定端，而抵靠端则用以抵靠第一支架的内壁。另外，前述健身器可以包含一滑轮，此滑轮与第二支架及凸部均同轴枢设于第一支架上。再者，前述健身器可以包含一坐垫，坐垫设于第一支架。此外，第二支架可以包含一靠垫，靠垫是用以承靠使用者的身体。
前述线性弹性件的第二端的容置空间与连杆的连接端所定义的限位关系是指在第二支架枢摆的过程中，连接端因第二端的特殊构造而被限制在容置空间中，致使连杆的连接端无法脱离线性弹性件的第二端，此限位关系可以大幅降低线性弹性件的无效弹动。

具体实施方式
请一并参阅图1～图6。图1绘示健身器的一实施方式的爆炸图。图2绘示图1的连杆与线性弹性件的局部剖视图。图3绘示图1的健身器的局部组装立体图。而图4与图5则分别绘示图1中第二支架摆动前与摆动后的局部剖视图。图6绘示图1的健身器的动作示意图。运用前述各图可以充份说明以下实施例的结构及运作。
请共同参照图1～图3，此健身器包含一第一支架100、一第二支架200、一凸部300、一线性弹性件400、一连杆500、一调整模块600、一滑轮700以及一坐垫800。其中凸部300包含一抵靠端310与一固定端320，线性弹性件400包含一第一端410与一第二端420，连杆500由一圆球体连接端510、一杆身520及一施力端530所组成，调整模块600包含一锁接件610、一螺锁件620及一螺配件630。
在上述健身器的结构中，第二支架200枢接于第一支架100，凸部300摆动连结第二支架200，凸部300与第二支架200同轴枢接于第一支架100，连杆500的施力端530是枢接于凸部300的固定端320。第二支架200在摆动的过程中，连杆500受凸部300带动伸缩线性弹性件400。线性弹性件400可位移、伸缩且弹动于第一支架100上，其中第一端410设于第一支架100。
线性弹性件400的第二端420包含一容置空间421，此容置空间421的末端向内收缩形成较小一开孔422，此开孔422的孔径小于圆球体连接端510的直径，且孔径大于杆身520的直径，借此将圆球体连接端510限位于第二端420的容置空间421中，并使杆身520可自由摆动地伸缩于开孔422内。
请共同参照图1与图4，当第二支架200摆动前，线性弹性件400透过弹力拉住连杆500，连杆500连动凸部300的固定端320，致使凸部300的抵靠端310紧密抵靠第一支架100的内壁。在此同时，由于凸部300与第二支架200同轴枢接于第一支架100，因此第二支架200会呈现稳定不动的状态，不会因靠垫210的重量或第二支架200本身的重量而导致第二支架200摆动或往下掉。
请共同参照图1与图5，当第二支架200摆动后，凸部300的抵靠端310远离第一支架100的内壁，凸部300的固定端320拉动连杆500的施力端530，并透过圆球体连接端510与第二端420的紧密连结将线性弹性件400拉长。当推压第二支架200的外力移离时，第二支架200会回复至摆动前的状态。此外，上述健身器的第二支架200与凸部300可以为一体连结。
调整模块600可调整地定位线性弹性件400的第一端410，其中调整模块600的锁接件610的两端分别锁接第一端410与螺锁件620的一端，而螺锁件620的另一端则与螺配件630螺锁。由于螺配件630是定位于第一支架100上，通过旋转螺配件630可位移螺锁件620，进而能够移动与调整锁接件610在第一支架100内的位置。若锁接件610的位置越靠近螺配件630，则线性弹性件400的第一端410就会越接近螺配件630，导致线性弹性件400的长度伸长，进而增加线性弹性件400在往复枢摆时的复位力；相反的，如果锁接件610的位置距离螺配件630越远，则线性弹性件400的第一端410就会越接近凸部300，导致线性弹性件400的长度缩短，进而降低线性弹性件400在往复枢摆时的复位力。
滑轮700与第二支架200及凸部300均同轴枢设于第一支架100上，第二支架200及凸部300可通过滑轮700相对于第一支架100往复地枢摆。此外，坐垫800可设于第一支架100，用以承载使用者的身体。而第二支架200更可包含一靠垫210，靠垫210可为发泡材质或缓冲材质，可用以承靠使用者的身体。
请参照图6，其绘示第二支架200可受力而相对第一支架100枢摆，并通过线性弹性件400所提供的复位力，而让第二支架200可复位为枢摆前的位置。使用者可坐于坐垫800上，而将背部靠于靠垫210，在此状况下，健身器可用以辅助仰卧起坐运动。再者，使用者亦可趴于健身器上方，而以胸口抵顶靠垫210，在此状况下，健身器可用以辅助伏地挺身运动。此外，使用者亦可将健身器置于脚下，让双脚分别踏于二靠垫210上，使用者的双脚可同时或交互下踩而使得第二支架200相对第一支架100枢摆，在此状况下，健身器可用以辅助踩踏运动。另外，使用者更可以侧卧、手握、抬脚于健身器等，而使用健身器进行各式各样的运动辅助。
由上述实施方式可知，本实用新型具有下列优点：其一，利用刚性的连杆连动线性弹性件的健身器可以快速地限制线性弹性件的位移、摆动及弹动范围，使线性弹性件能稳定地伸缩。其二，使用刚性连杆配合线性弹性件的特殊连结设计，可将线性弹性件限位于第一支架内且不会触碰到第一支架的内壁，可以避免因触碰而造成的声响与元件磨损，达到无噪音且延长元件寿命的功效。
虽然本实用新型已以实施方式揭露如上，然其并非用以限定本实用新型，任何熟悉此技艺者，在不脱离本实用新型的精神和范围内，当可作各种的更动与润饰，因此本实用新型的保护范围当视所附的权利要求书所界定的范围为准。
