Description

同轴两层式降落伞 技术领域
本发明与降落伞结构有关，特别是指不需足够高度以及复杂的开伞步骤即可达到完全开伞状态的同轴两层式降落伞。
背景技术
降落伞是应用空气阻力原理的一种气动力减速器，并通过一连接元件与一降落体相连接，且在使用时可展开阻风面积以增加降落体的运动阻力，使其减速下降与稳定其运动状态，借此能达到使降落体稳定且安全地降落到地面的目的。
然而已知所使用的降落伞在降落时必需具有足够的降落高度，方可使伞面受到足够的气流扰动产生的阻力予以展开，而且开伞步骤都极为复杂，非受过专业训练通常是无法轻易操作的。
因此，如何克服上述已知降落伞因开伞步骤复杂且需具有足够的降落高度才能使伞面完全展开等相关问题即为本发明首要研发课题。
发明内容
本发明要解决的技术问题是提供一种同轴两层式降落伞，不需要特定高度就能使用，而且亦不需要复杂的开伞步骤。
为解决上述技术问题，本发明提供的同轴两层式降落伞，所述降落伞包括设置在同轴心线的一内层充气囊体及一外层伞罩；所述内层充气囊体内部预先充填一氦气，且该内层充气囊体具有一导引部；所述外层伞罩内部设一充气空间，通过所述充气空间将内层充气囊体包覆于内，且所述外层伞罩底部邻近内层充气囊体的导引部位置设有一底端面，且所述底端面与内层充气囊体连接并环设有多个入气口。本发明的降落伞的内层充气囊体及外层伞罩的中心位置设置在同轴心线上，且内层充气囊体设置在外层伞罩的充气空间内，以及内层充气囊体及外层伞罩底端所连接的限位绳及连接绳的另一 端连接承载物；据此本发明的操作方式将氦气预先充填于内层充气囊体内部并产生一浮力，令内层充气囊体因内部的浮力向上浮起至一适当高度，而在内层充气囊体向上浮起，且当连接于内层充气囊体及外层伞罩下方的承载物降落时，向上的气流顺势由外层伞罩的入气口进入充气空间内部形成另一浮力，使外层伞罩的充气空间内部因气流进入而呈完全开伞状态；据此本发明的降落伞不需要特定高度就能使用，而且亦不需要复杂的开伞步骤即可使外层伞罩达到完全开伞的目的。
较佳地，内层充气囊体外侧部环设多个挠性片体，且该多个挠性片体连接于外层伞罩内侧，其功用是减少因向上气流与四周侧向气流的挤压造成外层伞罩相对于内层充气囊体的径向晃动或偏离同轴心线。
较佳地，内层充气囊体底部端缘设有一导引部，该导引部的弧面设计可减少向上气流进入入气口的阻碍，且具有高效率导引气流的优点。
较佳地，内层充气囊体外侧环设一塑型环体，且该塑型环体连接于外层伞罩底端，使原为挠性的外层伞罩底端面更具有抗拉强度。
较佳地，外层伞罩外观形成一由上往下渐缩的斜面，使向上气流作用在外层伞罩内外两侧压力更平衡，且使作用在外层伞罩外侧的轴对称径向作用力可以减低整个降落伞在降落时的左右前后晃动。
较佳地，塑型环体设有多个入气口。

为使审查员了解本发明的技术特征、内容与优点及其所能达成的功效，兹将本发明配合附图，并以实施例的表达形式详细说明如下，而其中所使用的附图，其主旨仅为示意及辅助说明书之用，未必为本发明实施后的真实比例与精准配置，故不应就所附的图式的比例与配置关系解读、局限本发明的实际实施上的权利范围在此先予以阐明。
本发明提供的一种同轴两层式降落，如图1所示，其具有一降落伞10，该降落伞10包括：
一内层充气囊体20，该内层充气囊体20内部预先充填氦气，以及内层充气囊体20外部邻近底部端缘设计一导引部21，该导引部21为一弧面210，又导引部21底部连接一限位绳22，限位绳22另一端则连接一具有重量的承载物T；
一外层伞罩30，该外层伞罩30将内层充气囊体20包覆于内部，并在外层伞罩30与内层充气囊体20之间形成一充气空间31，且外层伞罩30底部邻近内层充气囊体20的导引部21位置设有一底端面 32，且该底端面32与内层充气囊体20连接并环设有多个入气口320，另外层伞罩30顶端的轴对称角设一泄气口33而在底部环设有多个连接绳34，连接绳34另一端连接承载物T，以及连接绳34邻近承载物T位置环接一固定环340。
经由上述构件组成本发明的降落伞10，操作上请参阅图2及图3所示，该降落伞10的内层充气囊体20及外层伞罩30的中心位置设置在同轴心线H上，且因内层充气囊体20内部已预先充填有氦气借以产生一浮力F，因氦气的气体密度远小于外在空气密度，因此内层充气囊体20内部所产生的浮力F会令内层充气囊体20向上浮起至一适当高度，且当连接于内层充气囊体20及外层伞罩30下方的承载物T降落时，外在空气向上之气流40得顺势由外层伞罩30的入气口320进入充气空间31内部形成另一浮力F1，使外层伞罩30的充气空间31内部因气流40进入而呈完全开伞状态，此时内层充气囊体20及外层伞罩30所连接的限位绳22及连接绳34会连带往上被拉直，其中限位绳22在被拉直后可令内层充气囊体20浮在空中时得被限制在一轴对称的中心线H位置不会乱晃，据此浮力F更得以准确地在内层充气囊体20内部中心形成，换言之内层充气囊体20内部的浮力F愈是准确地作用在中心线H位置，则愈能避免内层充气囊体20因受力方向不一致导致严重倾斜。
进一步说明，当内层充气囊体20因内部的浮力F向上浮起后，并令降落伞10由高空往下降落，而通过限位绳22及连接绳34所连接的承载物T具有重量，因此降落伞10在降落时得呈现一自由落体的现象，同时大气中会产生多个不同方向的气流40，此时因内层充气囊体20的底部端缘设计具有弧面210的导引部21，通过弧面210可导引大部份气流40顺势由外层伞罩30的底端面32的入气口320进入外层伞罩30的充气空间31内部并形成浮力F1，而呈现完全开伞状态。
因此本发明的降落伞10不需要特定高度才能使用，而且亦不需要复杂的开伞步骤即可使外层伞罩30达到完全开伞的效果，此外外 层伞罩30底端所连接的连接绳34可通过固定环340达到局限目的，令连接绳34均匀地被撑开避免相互重叠或缠绕现象。
再者，请参阅图4所示，为本发明另一实施例的立体示意图，本发明的降落伞10包括：
一内层充气囊体20，该内层充气囊体20内部预先充填一氦气，以及内层充气囊体20外部环设多个绕性片体23以及底部端缘设有一导引部21，导引部22为弧面210设计，又导引部21底部连接一限位绳22，限位绳22另一端连接一具有重量的承载物T；
一外层伞罩30，该外层伞罩30将内层充气囊体20包覆于内部，并在外层伞罩30与内层充气囊体20之间形成一充气空间31，且外层伞罩30顶端的轴对称角设一泄气口33，而外层伞罩30底端环设有多个连接绳34，该连接绳34另一端连接承载物T，连接绳34邻近承载物T位置环接一固定环340；
一刚性材质的塑型环体50，该塑型环体50环绕设置于内层充气囊体20及外层伞罩30底端之间，且塑型环体50设有多个入气口51。
经由上述构件组成本发明的降落伞10，操作上请参阅图5及图6所示，该降落伞10的内层充气囊体20及外层伞罩30的中心位置设置在同轴心线H上，且内层充气囊体20设置在外层伞罩30的充气空间31内，以及在内层充气囊体20外侧且对应外层伞罩30底部之间连接塑型环体50，并利用塑型环体50的刚性材质使外层伞罩30得以环绕方式包覆内层充气囊体20并相互连接，除此内层充气囊体20利用多个挠性片体23连接于外层伞罩30内侧，令外层伞罩30得以均匀且稳固地被撑开，而被撑开后的外层伞罩30外观则形成一由上往下渐缩的斜面300。
兹因内层充气囊体20内部已预先充填有氦气故得产生一浮力F，因该氦气的气体密度远小于外在空气密度，因此内层充气囊体20内部所产生的浮力F会令内层充气囊体20向上浮起至一适当高 度，且当连接于内层充气囊体20及外层伞罩30下方的承载物T降落时，外在空气向上的气流40顺势由塑型环体50的入气口51进入充气空间31内部形成另一浮力F1，使外层伞罩30的充气空间31内部因气流40进入而呈完全开伞状态。
值得一提的是，为避免降落伞10在降落的过程中内层充气囊体20及外层伞罩30受到来自各个方向气流40的影响而产生左、右前后晃动，甚至有严重倾斜产生失控降落之虞，因此内层充气囊体20利用多个挠性片体23对外连接外层伞罩30，令外层伞罩30得以固定型态被撑开时，并且稳固地与内层充气囊体20接合在整个圆周上保持径向的等距，确保空气表面压力可均均地作用在内层充气囊体20外部相对外层伞罩30内部的充气空间31内。
综上所述，本发明的同轴两层式降落伞确实具有以下功效：
第一点、本发明将内层充气囊体20预先充填氦气，因此在降落伞10未正式降落前，内层充气囊体20内部即已先产生浮力F并向上浮起至一适当高度，令限位绳22及连接绳34被拉直，而在内层充气囊体20向上浮起至适当高度后，外层伞罩30的充气空间31内部形成会另一浮力F1，同时令外层伞罩30的充气空间31内部因气流40进入而呈完全开伞状态，因此本发明的降落伞10不需要特定高度就能使用，而且亦不需要复杂的开伞步骤即可使该外层伞罩30达到完全开伞的效果。
第二点，本发明将内层充气囊体20及外层伞罩30设置在同轴心线H上，因此不论是浮力F、F1或大气中的气流40以及空气表面压力作用在其表面上时，内层充气囊体20及外层伞罩30中心可以保持在同心的位置，又因增设多个挠性片体23，挠性片体23向内连接内层充气囊体20及向外连接外层伞罩30，所以内层充气囊体20及外层伞罩30设置在同轴心线H上形成更相互牵制的效果，因此降落伞10在降落的过程中内层充气囊体20及外层伞罩30在左右与前后方向并不会产生过大的相互间的晃动偏离，导致严重倾斜或晃动的失控现象。
第三点、外层伞罩30顶端的轴对称角处设泄气口33，使气流40能平均地由四个泄气口33向外透出对流，令降落伞10在降落时能更为平稳并减少晃动现象。
第四点、外层伞罩30外观由上往下形成一渐缩状的斜面300，通过此斜面300具有一斜度设计，使大气中的来自各个方向的气流40都可被适当地导引而往上作用在外层伞罩30的内外两侧，令外层伞罩30能更为平稳的降落。
第五点、通过塑型环体50为一超轻量的刚性材质构成，因此不论是在收折或开伞状态，塑型环体50皆不会有变形之虞，因为塑型环体50设有多个入气口51可使大气中气流40均匀且更有效率地进入外层伞罩30内部的充气空间31产生充气的效果。
以上通过具体实施例对本发明进行了详细的说明，但这些并非构成对本发明的限制。在不脱离本发明原理的情况下，本领域的技术人员可做出许多变形和等效置换，这些也应视为本发明的保护范围。
