Description

吊扇叶片的收合伸展结构 技术领域
本发明涉及一种吊扇，特别是指一种不使用时呈收合状态、启动旋转时自动向外伸展的叶片，提供收合与伸展的动作顺畅且吊扇整体外观具新颖与特殊美感，可提升产业竞争力。
背景技术
按，目前市面上常见吊扇结构分成固定式与起飞式两大类。固定式是指吊扇叶片连接于外转式马达的旋转盘上，不论旋转或停止都呈固定向外伸张伸状态。起飞式是指吊扇叶片活动枢设于旋转盘上，而该旋转盘同样位于外转式马达上，在停止时向内收合，旋转时则向外伸张的状态。起飞式又因叶片伸张方式的不同分成二种。第一种其叶片系朝旋转盘的水平方向运作(向外伸张、向内收合的型态)，通过一主齿盘与行星式设置的小齿轮配合，使得叶片于停止时因弹性件的限制向内收合，于旋转时则因离心力作用而向外伸张状态，如中国台湾专利号M345145案、专利号M387920案、专利号M482700案等。第二种其叶片于收合时为呈下垂型态，如中国台湾专利号M244370案及中国专利号ZL200620115610.7等，此等叶片与旋转盘之间凭借可上、下枢摆的支撑臂连接，于未旋转时其叶片系呈下垂于旋转盘周侧收合的结构。其具有方便清洁功效，且与固定式吊扇叶片比较，不会有因擦拭而损坏各叶片的缺弊产生。然而，在驱动旋转时则因支撑臂的上、下枢摆运作，必须克服自身力臂长度以及要承受叶片重量，致使带动其旋转的旋转盘(马达)负载较高，而容易造成旋转晃动、偏摆不稳以及不顺畅的情形产生，影响吊扇的使用寿命，是为亟待改进的缺弊。
本发明设计人基于上述现有吊扇的缺失，积极努力开发、研究改良，推出“吊扇叶片的收合伸展结构”，得彻底解决现有的缺弊，提供收合与伸展的动作顺畅且吊扇整体外观具新颖与特殊美感，可提升产业竞争力。
发明内容

若干弹性件，设置于各第一枢轴端与各第一枢接部之间，用以限制各延伸臂向外伸展的状态，并提供各延伸臂的第二枢轴端以各第一轴枢件为中心往上枢摆并靠近于转动件的作用力，各叶片则以各第二轴枢件为中心往下枢摆而收合于转动件的周侧。
在进一步的技术方案中，所述连接臂中间部位向外凸伸有抵持杆，当延伸臂枢摆靠近转动件时，抵持杆抵持延伸臂，限制其枢摆收回的状态。
在进一步的技术方案中，所述弹性件为扭力弹簧，具有呈U形的连接部，以及设在连接部二端的两个螺旋簧圈，各螺旋簧圈分别设有插入端，所述插入端插接在第一枢接部两侧，而第一轴枢件穿枢通过两个螺旋簧圈，且连接部顶抵在延伸臂一侧。
在进一步的技术方案中，该连接臂的第一枢接部具有呈间隔设置的两个侧片，该连接臂的两个侧片上分别设有穿孔，该固接臂的第二枢接部同样具有呈间隔设置的两个侧片，该固接臂的两个侧片上也分别设有穿孔，该延伸臂的第一枢轴端与第二枢轴端都具有呈间隔设置的两个侧片，且各侧片上也分别设有穿孔，通过第一轴枢件穿过第一枢接部与第一枢轴端相对应的穿孔，以及第二轴枢件穿过第二枢接部与第二枢轴端相对应的穿孔，能够将连接臂、延伸臂及固接臂完成枢接。
在进一步的技术方案中，该第一枢接部的各该侧片上还设有小孔，各小孔设于各穿孔的周侧，提供扭力弹簧二侧的插入端插入组设。
在进一步的技术方案中，该第一轴枢件包括轴杆及C形扣环，且轴杆末端设 有提供C形扣环嵌设的环沟。
在进一步的技术方案中，该第二轴枢件包括轴杆及螺帽，且轴杆末端设有提供螺帽螺合的外螺纹。
综合上述针对本发明所描述的各项技术特征下，其优点在于该转动件与该叶片之间通过连接臂、固接臂以及延伸臂连接的结构，使得叶片的伸展动作为一层一层往外伸出的形式，达到动作顺畅优美，以及解决前述现有叶片旋转晃动、偏摆不稳以及不顺畅的缺弊，且本发明吊扇收合时其叶片包覆于该转动件外周侧，整体外观犹如含苞待放的花朵，具新颖与特殊美感，而可促进产业升级。因此本发明可说是一种相当具有实用性及进步性的发明，相当值得产业界来推广，并公诸于社会大众。

而，承上所述的本发明吊扇叶片的收合伸展结构，请配合参阅第3、图4及图5所示，其中该连接臂3于中间部位向外凸伸一抵持杆32，于该延伸臂5枢摆靠近于该转动件2时，该抵持杆32抵持该延伸臂5以限制其枢摆收回的状态。
又，其中该弹性件6为一扭力弹簧，具有一概呈U形的连接部61以及设于该连接部61二端的二螺旋簧圈62，各该螺旋簧圈62各分别具有一插入端63，插接于该第一枢接部31的二侧，该第一轴枢件8穿枢通过该二螺旋簧圈62，该连接部61顶抵于该延伸臂5的一侧(见图5所示)。
再者，本发明吊扇叶片的收合伸展结构，如图4中所示，其中该连接臂3的第一枢接部31具有呈间隔设置的两个侧片311，该两个侧片311上分别设有一穿 孔312，该固接臂4的第二枢接部41同样具有呈间隔设置的两个侧片411，该两个侧片411上也分别设有一穿孔412，该延伸臂5的第一枢轴端51与第二枢轴端52都具有呈间隔设置的两个侧片511、521，且各侧片511、521上也分别设有一穿孔512、522，则该第一轴枢件8穿过该第一枢接部31、第一枢轴端51相对应的穿孔312、512，该第二轴枢件9穿过该第二枢接部41、第二枢轴端52相对应的穿孔412、522完成枢接。
另，该第一枢接部31的各该侧片311上更分别设一小孔313，该小孔313设于该穿孔312的周侧，则该弹性件6其二螺旋簧圈62各具有的插入端63得以分别插入于该小孔313。
该第一轴枢件8包括一轴杆81及一C形扣环82，该轴杆81穿过该第一枢接部31、第一枢轴端51相对应的穿孔312、512后，以该C形扣环82嵌设于该轴杆81末端的一环沟83。
该第二轴枢件9包括一轴杆91及一螺帽92，该轴杆91穿过该第二枢接部41、第二枢轴端52相对应的穿孔412、522后，以该螺帽92与该轴杆91末端的外螺纹93螺合。
依据上述针对本发明所阐述的内容，请配合参阅图1与图3所示，当该驱动装置1未启动，该转动件2未绕着该心杆11转动时，因各该弹性件6的弹力限制，使各该延伸臂5其第一枢轴端51以第一轴枢件8为中心，其第二枢轴端52为往上枢摆并靠近该转动件2的型态，且因叶片7自身的重力，使该固接臂4其第二枢接部41以第二轴枢件9为中心往下枢摆，则各该叶片7将呈向下垂摆的型态，且往内靠拢收合于该转动件2的周侧，提供方便于对叶片7进行清洁擦拭动作，不会有现有吊扇于擦拭时易导致叶片损坏的缺弊产生，又，该延伸臂5枢摆靠近于该转动件2时，设于该连接臂3中间部位向外凸伸的该抵持杆32，提供抵持着该延伸臂5以限制该延伸臂5枢摆收回的状态，如图5与图6所示，可避免叶片7收合时太接近并碰触到该驱动装置1、该转动件2；而，当启动该驱动装置1使该转动件2转动时，则因离心力作用，使得叶片7凭借该固接臂4以该第二轴枢件9为中心被拉直并向上枢摆，此时该延伸臂5并克服该弹性件6的弹力，使其第二枢轴端52向下枢摆，则该第二枢轴端52将朝远离该转动件2的方向往外伸展，各该叶片7将以该驱动装置1为中心往外伸展，且各该叶片7旋转时产生送风效果；本发明吊扇叶片的收合伸展结构其叶片7将通过该固接臂4、该延伸臂5以及 该连接臂3连接至该转动件2，当转动件2启动旋转时，叶片7的伸展动作为一层一层往外伸出的形式，所以动作顺畅优美，彻底解决前述叶片旋转晃动、偏摆不稳以及不顺畅的缺弊，确实能达成预期的发明目的。本发明吊扇叶片的收合伸展结构，可延长吊扇的使用寿命，具有实用性以及进步性，且吊扇整体外观不论是收合或伸展(如图1与图2所示)都具新颖与特殊美感，可提升产业竞争力。由上所述者仅为用以解释本发明的较佳实施例，并非企图据以对本发明做任何形式上的限制，是以，凡有在相同的发明精神下所做有关本发明的任何修饰或变更者，为其他可据以实施的型态且具有相同效果者，都仍应包括在本发明意图保护的范畴内。
综上所述，本发明“吊扇叶片的收合伸展结构”，其实用性符合产业上发展所需，所揭示的结构也前所未有，具有新颖性。本发明较现有更具功效，具有创造性无疑虑，其完全符合我国专利法申请条件，乃依法提起专利申请，敬请钧局早日审查，并给予肯定。
