Description

踏步机 技术领域
本发明涉及一种踏步机，且特别涉及一种可随着踩踏升降而左右摇摆的踏步机。
背景技术
踏步机为一种室内健身器材，其利用左右踏板的上下摆动模拟上楼梯动作路径，借此训练左右腿肌肉。目前公知踏步机不仅可模拟上下摆动的动作，也有新颖的踏步机其踏板不仅可上下摆动且可同时旋转摆荡，另一方面训练腰部力量并可增加身体平衡感。
公知踏步机中左右踏板采用复杂的连动系统，公用连动系统包含左右踏板下设置可摆动的杠杆，利用杠杆原理，当任一踏板受重力往下抵住杠杆的一端时，则另一踏板受杠杆另一端推力往上。或者在左右踏板下设置可随圆心转动的V型摆臂，利用圆心直径等长且夹角固定的概念，当任一踏板受重力往下抵住V型摆臂的一端时，则另一踏板受V型摆臂另一端推力往上。
此外，公知踏步机中左右踏板的旋转摆动在将两个踏板以枢轴枢设在支架上，让踏板可相对支架旋转摆动。
然而，前述公知踏步机的连动机构，其左右踏板的动作路径均以固定，踩踏的行程以及旋转摆动的角度都无法针对不同使用者的需求再进行变动。且前述公知踏步机必须以复杂的连动系统达成升降及摇摆的动作，形成产品成本的提高。
发明内容
本发明的目的在于提供一种踏步机，其避免使用复杂的连动系统，且可改善公知踏步机无法调整踩踏的行程以及旋转摆动的角度的缺点，借此 本发明可针对不同使用者的需求进行适当调整。
根据本发明一个实施方式提供一种踏步机，包含基座、连动杆、两个踏板以及两个调整机构。连动杆枢设于基座。连动杆具有可同心转动的两端。每个踏板包含踏板件以及踏板臂，踏板臂连接踏板件，且踏板臂枢设于连动杆的一端以令踏板件往复升降。每个调整机构包含挡件及挡块，挡件设于踏板臂，挡件具有至少一个第一抵挡面。挡块与连动杆具有预设距离，挡块具有至少一个第二抵挡面以抵靠挡件的第一抵挡面。其中，当踏板往重力方向下降，则其中一个第一抵挡面与第二抵挡面倾斜重力方向带动连动杆的一端，而使连动杆的另一端同心转动，并使另一第一抵挡面受另一第二抵挡面推抵，致使另一踏板摆动并上升。
借此，踏步机的连动杆以及调整机构达成以简易结构可达成往复升降踏步功能。
根据本发明一个实施方式的一个实施例，踏步机还包含两个回复机构，每个回复机构分别连接连动杆的端及基座。每个回复机构可为连杆及拉伸弹簧。每个回复机构可为钢索及拉伸弹簧。每个回复机构可为连杆及压缩弹簧。每个回复机构可为气压缸或油压缸。踏步机中的基座包含中心部、延伸部及两个侧部，中心部用于设置两个挡块，延伸部从中心部向外垂直延伸，两个侧部分别连接中心部的两端，两个侧部呈八字形并列，且两个侧部内呈中空以分别设置两个回复机构。连动杆还包含圆心部，其位于连动杆中央，且圆心部以枢轴枢接于延伸部的外端，使连动杆可枢转。两个踏板皆包含枢转部，每个枢转部一体连接于每个踏板臂并分别枢接于连动杆的两端，使每个踏板臂可相对连动杆枢转。每个挡件的第一抵挡面可旋转地抵靠每个挡块的第二抵挡面。每个挡件的第一抵挡面的数量可为多个。且多个第一抵挡面具有相异接触面积。第一抵挡面可为弧面，且第一抵挡面可由弹性材质所制成。

因此，由前述踏步机的实施方式及实施例可得知，本发明利用连动杆及调整机构的配合，当踏板受重力方向往下时，则第一抵挡面抵靠第二抵挡面并倾斜重力方向，不仅使连动杆的两端同心转动，且同时使另一第二抵挡面倾斜推抵另一第一抵挡面，而带动另一踏板转动并上升。此外，本发明利用设于连动杆两端的回复机构，使左右踏板的动作分别受到其回复力带动而恢复起始状态。

具体实施方式
请参照图1、图2及图3，其中图1及图2为根据本发明一个实施方式的一种踏步机的立体示意图及爆炸示意图，图3为图2的踏步机的仰视图。踏步机100包含基座200、连动杆300、两个踏板400、两个调整机构500以及两个回复机构600。
基座200用于稳定地置放于平面上。基座200包含中心部210、延伸部220及两个侧部230，延伸部220从中心部210向外垂直延伸，两个侧部230分别连接中心部210的两端，两个侧部230呈八字形并列，且两个侧部230内部呈中空。
连动杆300枢设于基座200，且连动杆300具有可同心转动的两端310以及圆心部320，圆心部320位于连动杆300中央，且圆心部320以枢轴330枢接于延伸部220的外端，使连动杆300可相对基座200枢转。
每个踏板400均包含踏板件410、踏板臂420以及枢转部430，踏板件410用于供采踏，踏板臂420呈L型连接踏板件410。枢转部430一体连接于踏板臂420，且每个枢转部430分别枢接于连动杆300的两个端310，使每个踏板臂420可相对连动杆300枢转以令踏板件410往复升降。其中，图3省略踏板件的描述。
每个调整机构500均包含挡件510及挡块520，挡件510设于踏板臂420，挡件510具有至少一个第一抵挡面511，本实施方式中第一抵挡面511可为弧面，且第一抵挡面511可由弹性材质所制成。两个挡块520分别与连动杆300具有预设距离，挡块520设于中心部210且具有至少一个第二抵挡面521以抵靠挡件510的第一抵挡面511。本实施方式中第二抵挡面521的数量为四个。
每个回复机构600分别设于两个侧部230内部，每个回复机构600分别连接连动杆300的端310以及基座200，本实施方式中回复机构600为连杆610及拉伸弹簧620，连杆610一端连接连动杆300的端310，且连杆610另一端连接拉伸弹簧620。
以下请参照图2、图4A、图4B及图4C，并以图4A、图4B及图4C说明踏步机100的动作示意图。图4A为图2的踏步机100的动作示意图、图4B及图4C为图4A的踏步机100两侧的动作示意图。其中，当踏板400往重力方向g下降时，则设于此踏板400上挡件510的第一抵挡面511与挡块520的第二抵挡面521倾斜重力方向g，迫使连动杆300的两端310同心转动，同时，另一挡块520的第二抵挡面521倾斜推抵另一挡件510的第一抵挡面511，使另一踏板400上升。因此，通过连动杆300的同心转动、挡件510及挡块520的抵靠设置，使左右踏板400可完成上下摆动的动作。
然而，必须强调的是踏步机100的踏板400受到挡块520及挡件510的限制，不仅可连动而上下摆动，且可同时左右摇摆。请同时参照图2、图5A及图5B，其中图5A为图2的踏步机100中挡块520与连动杆300的预设距离L以及踏板臂420上下摆动角度θα的示意图，图5B为图2的踏步机中踏板臂420左右摆动角度θβ的示意图。由于每个踏板臂420不论往上或往下，其踏板臂420上的挡件510都会受到挡块520的抵顶，但连动杆300为绕圆心转动，使得踏板臂420不仅可上下摆动且随连动杆300而左右倾摆。而假设踏板臂420高度及挡块520高度固定，挡块520与连动杆300的预设距离L越长，将导致踏板臂420的上下摆动角度θα及左右摆动角度θβ越小，使用者根据此概念变化挡块520设置位置，借此可调整踏步机100的踏板行程及摆幅角度。此外，本实施方式中挡块520具有四个第二抵挡面521，当四个第二抵挡面521具有相异接触面积时，同样可用于调整踏板臂420的上下摆动角度θα及左右摆动角度θβ。
请同时参照图6、图7及图8，其中图6为根据本发明一个实施例的一种踏步机100的示意图。图7为根据本发明另一个实施例的一种踏步机100的示意图。图8为根据本发明又一个实施例的一种踏步机100的示意图。
如图6所示，本实施例中不限定挡块520及挡件510的设置位置，因此将挡块520及挡件510的位置互相置换，只要挡块520及挡件510的相对位置不变，同样可达到调整踏步机100的踏板行程(即上下摆动角度)及左右摆幅角度的效果。如图7所示，本实施例中挡件510具有可旋转圆面，使踏板400在踩踏的动作中更为顺畅。如图8所示，本实施例将图7中的挡块520及挡件510的位置互相置换。
请同时参照图9、图10及图11，其中图9为根据本发明再一个实施例的一种踏步机100的爆炸示意图。图10为根据本发明另一个实施例的一种踏步机100的爆炸示意图。图11为根据本发明又一个实施例的一种踏步机100的爆炸示意图。
如图9所示，本实施例的回复机构600以钢索610a搭配拉伸弹簧620来提供回复力。如图10所示，本实施例的回复机构600以连杆610搭配压缩弹簧620a来提供回复力。如图11所示，本实施例的回复机构600可为气压缸或油压缸，借此提供回复力。因此，本本领域技术人员可针对回复机构600自由变化其结构组合。
本发明的踏步机具有以下优点：
1.踏步机的连动杆以及调整机构以简易结构可达成往复升降踏步功能。
2.针对踏板上下摆动而言，本发明的调整机构以及连动杆结构比起公知踏步机利用杠杆或V型摆动的连动机构更为稳定。
3.而调整机构中挡块及挡件倾斜重力方向的结构以及连动杆配合，不仅可让踏板上下摆动，还可连动踏板左右摆动。
4.根据使用者所需的踏板行程及摆动幅度，挡件及挡块的位置可互相置换，且挡件的第一抵挡面以及挡块的第二抵挡面的数量可变化，挡块的第二抵挡面的接触面积也可随的变化。
虽然本发明已以实施方式公开如上，然其并非用于限定本发明，任何本领域技术人员，在不脱离本发明的精神和范围内，可作各种不同的选择和修改，因此本发明的保护范围由权利要求书及其等同形式所限定。
