Definitions

  • the invention belongs to the field of blinds, and in particular relates to a blind without a drawstring system.
  • Venetian blinds which are folded from many sheets, are not only ventilated, shaded and soundproofed, but also can be shaded and cooled to decorate the living room.
  • Louver is typically mounted in or on a window that is movable between an open position and a closed position. When in the open position, the shutter device allows light and sight to pass through the blinds and windows, while when in the closed position, there is little light to pass through and the line of sight cannot pass through the window.
  • Conventional louvers include a plurality of adjacent louver blades that are generally arranged in a horizontal direction. Each blade comprises an elongated, flat element whose length depends on the size of the window to be covered.
  • all of the blades are attached to a generally upright shaft, and by moving the shaft along a vertical axis, all of the blades rotate uniformly about their common mounting axis. Therefore, when the shaft moves vertically, all the blades move to the open position in unison, at which point each blade moves to a position that is approximately horizontal. By moving the shaft in a relatively vertical direction, all of the blades move about their pivot axis to achieve a substantially vertical position. When in a horizontal position, an open gap is formed between adjacent vanes to facilitate light passage and to allow people to see through the blinds. When in a vertical or substantially vertical position, the blade substantially blocks all light and line of sight because the spacing between the blades is slightly less than the width of each blade, such that each blade slightly overlaps the adjacent blade, and This closes the blinds.

Description

一种用于无拉绳百叶窗的卷绳装置及一种无拉绳系统百叶窗 技术领域
本发明属于百叶窗领域，具体的涉及一种无拉绳系统的百叶窗。
背景技术
百叶窗帘，由许多薄片连接折叠而成，不仅具有通风、遮光和隔音的用途，而且还可以遮阳降温、装饰居室。百叶窗一般安装于窗户之内或之上的装置，其能在打开位置和关闭位置之间移动。当处于打开位置时，百叶窗装置允许光线和视线透过百叶窗及窗户，而当处于关闭位置时，则几乎没有光线能透过，并且视线也不可能再透过窗户。传统的百叶窗包括多个相邻的百叶窗叶片，这些叶片通常沿着水平方向布置。每一叶片包括细长、扁平状元件，其长度取决于所要覆盖的窗户的尺寸。在常见的百叶窗布置中，所有的叶片都连接于一根通常为直立的轴上，并且通过沿着垂直轴线移动该轴时，所有叶片都会一致围绕它们共同的安装轴旋转。因此，当轴垂直移动时，所有叶片会一致移动到打开位置，此时每一叶片都移动至大约为水平的位置。通过沿相对垂直的方向移动轴，所有叶片都绕它们的枢轴线运动以达到大致垂直的位置。当处在水平位置时，在相邻的叶片之间形成一开口间隙便于光线通过，并且使得人们视线能透过百叶窗。当处在垂直或者基本垂直的位置时，叶片基本上隔断了全部光线和视线，因为叶片之间的间距略微地小于每一叶片宽度，从而使得每一叶片与相邻的叶片略微地重叠，并由此来关闭百叶窗。
公开号为CN10521049A、公开日为2016年01月06日的中国发明专利申请公开了一种传统的百叶窗帘的结构，包括具有孔的百叶窗帘片、带有横格线的布梯、配有垂重手柄的升降循环拉绳、提升带、上梁组装系统和下梁，所述上梁组装系统中的上梁的一端装有快速升降制头，所述上梁组装系统中的上梁的另一端装有侧封盖，所述上梁组装系统内装有一根铁条横轴，其特征在于：在所述铁条横轴的一端装入快速升降制头，在所述铁条横轴的另一端穿入与带孔的百叶窗帘片相对应孔数的无阻力卷带器组合件，并将所述铁条横轴与无阻力卷带器组合件中的提升带卷盘和布梯转角机构配装。然而具有拉绳的百叶窗，由于其拉绳游离于窗体外，而使得拉绳成为儿童的安全隐患，易造成儿童的意外伤害。此外手动控制的拉绳由于使用者用力的大小及方向存在不同，容易对百叶窗造成损伤，减少使用寿命。
公开号为CN101426998的中国专利申请公开了一种用于百叶窗的百叶窗自动控制装置，百叶窗具有一致枢转的多个板条，该百叶窗自动控制装置包括：马达；具有主体部分 和连接部分的板条接口，连接部分具有构造成与百叶窗板条之一的端部的至少一部分吻合且连接到其上的外形；以及由马达驱动且可连接到板条接口上以便在第一位置与第二位置之间移动板条接口的移动组件。
发明内容
本发明提供了一种全新的无拉绳系统百叶窗，由于拉绳属于内置拉绳，位于百叶窗内部，因此避免了游离拉绳存在的安全隐患。本发明中，卷绳装置与马达为独立设置的部件，因此在使用中易于更换，增加了百叶窗的使用寿命。本发明提供了一种全新的固定座的结构设计，该固定座既适用于带状梯带也适用于绳状梯带，适用于多根梯带。本发明提供的卷绳装置使拉绳生产摩擦阻力来保持百叶窗下梁停留在不同位置处于停止状态，防止下滑或反弹。此外，本发明提供的百叶窗所使用的马达采用了一种新的组合方式，不但在马达外壳进行改进，利用卡扣装置进行组装，同时还使用了固定架，将马达的外壳、蜗卷弹簧、大小滚轮从整体上加以固定组合，该组合方式与传统的焊接组装相比操作更加简单，并且后期维修更加灵活。
本发明提供了一种用于无拉绳百叶窗的卷绳装置，包括固定座、固定器、卷绳筒(71)和后盖和铁芯，卷绳筒带有单向阻尼离合器的。由于卷绳筒带有单向阻尼离合器，使得卷绳筒独自即可实现窗帘的拉起或放下的操作，而现有技术中的卷绳筒必须与马达设置在一起，并依靠马达的作用才能实现窗帘的拉起或放下的操作。由于本发明没提供的卷绳筒带有单向阻尼离合器，使得所述卷绳筒在独立于马达的情况下就可以具有窗帘的拉起或放下的操作能力，实现了卷绳筒与马达的分开的单独设置，有利于安装，并且在使用磨损后卷绳筒和马达可以单独更换，节约了生产及使用成本。同时在生产中可根据需要在一组窗帘上设置一至多个卷绳筒，而不必要求每一个卷绳筒配备一个马达，装配方式灵活并且节约了生产成本。
优选的是，所述单向阻尼离合器的形成阻尼的方式包括橡胶阻尼、塑料阻尼、阻尼胶带、弹簧或紧配合至少一种。现有技术中可形成阻尼的装置均适用于本发明，优选的是橡胶阻尼或塑料阻尼或弹簧或紧配合，优选使用弹性橡胶，优选使用夹紧弹簧。
上述任一项中优选的是，还包括夹紧弹簧、单向轴心和钢珠，所述钢珠、单向轴心及夹紧弹簧组成所述单向阻尼离合器。所述夹紧弹簧用于所述单向阻尼离合器产生阻尼。上述任一项中优选的是，夹紧弹簧的一端以紧配合的方式套在单向轴心上，所述夹紧弹簧的另一端在端部设有档脚，所述固定座设置有夹紧弹簧档脚槽，所述夹紧弹簧的档脚卡在所述固定座的夹紧弹簧档脚槽内并固定。当百叶窗无外力作用下，百叶窗下梁和叶片自重的 作用使百叶窗受到向下的力，夹紧弹簧产生阻力，克服重力作用，阻止单向轴心转动，保持百叶窗静止。
上述任一项中优选的是，所述单向轴心套在卷绳筒一端的卷绳筒内腔内，所述单向轴心与所述卷绳筒内腔间隙配合。所述单向轴心表面设有限制钢珠滑动的轨迹，所述卷绳筒内腔设置有滑槽。优选的是，所述卷绳筒的一端含有中心轴，所述滑槽设置于所述中心轴与卷绳筒内腔的内壁之间。所述单向轴心套在卷绳筒一端的卷绳筒内腔内并安装于所述中心轴上，所述单项轴心与卷绳筒内腔滑槽之间形成的间隙为所述滚珠滚动的空间。所述卷绳筒的另一端与后盖连接。

具体实施方式
下面结合附图以具体实施例对本发明作进一步描述需要说明的是，本发明中所称的“第一”、“第二”并不是对相应技术特征在数量上的限定，而是为区分相关技术特征而作出的命名。
实施例1
实施例1提供了本发明一种无拉绳百叶窗的优选实施方式，如图1，2所示，所述无拉绳窗帘包括上梁1、下梁2、叶片4、拉绳3、卷绳装置7、马达6和转轴5，本实施例中的拉绳3无特殊说明的情况下，均为设置于百叶窗内部的内置拉绳。
如图3所示，卷绳装置7由固定座73、固定器72、铁芯74、夹紧弹簧76、单向轴心75、钢珠、卷绳筒71、后盖77等组成。
如图4，5所示，卷绳装置7各零件按照以下连接方式连接：固定座73两侧设置有拉绳孔，铁芯74卡在固定座73两侧的拉绳孔的铁芯固定槽内并固定；夹紧弹簧76套在单向轴心75上，并与之适当的紧配合，紧配合的作用在于使夹紧弹簧76与单向轴心75之间的连接具有牢固性，并不会脱落。夹紧弹簧76端部设有档脚760，档脚760卡在固定座73上设置的夹紧弹簧档脚槽内；单向轴心75套在卷绳筒71一端的卷绳筒内腔710内，与卷绳筒71间隙配合，未装夹紧弹簧76和钢珠情况下，能自由转动；单向轴心75表面设有限制钢珠滑动的轨迹750；卷绳筒内腔710设置有滑槽，钢珠位于单向轴心75与卷绳筒内腔710之间，并同受约于单向轴心75表面上的限制钢珠滑动的轨迹750和卷绳筒内腔710滑槽共同组成的区域内活动；固定器72上具有固定梯带8的卡槽，固定器72安装于固定座73内。
实施例1中的无拉绳百叶窗还包括卷绳装置安装架78，所述卷绳装置7通过卷绳装置安装架78安装于转轴5上。
实施例1中，如图6，7所示，马达6包括外壳、固定架69、蜗卷弹簧65、小滚轮67、大滚轮68等。马达6内各零件按照以下连接方式进行连接：蜗卷弹簧65套在小滚轮67 上，蜗卷弹簧65设置在其外端末端的卡钩650卡在大滚轮68出设置的蜗卷弹簧卡槽内并固定；大小滚轮由两侧外壳固定并转动顺畅，固定架69限制并固定马达6两侧外壳。
所述百叶窗按照以下方式进行组件连接：拉绳3头部一端固定在卷绳筒71端部(靠后盖77)，拉绳3另一端跨过固定座73侧面铁芯74并穿过，再穿过固定座73底部的拉绳穿孔730后，穿过全部叶片4，最后固定在下梁2上，卷绳装置7和马达6由转轴5连接，使卷绳筒组间实现同步转动。马达6内大小滚轮间蜗卷弹簧65呈"S"形，为拉绳3收起时提供回卷力；在百叶窗收起过程中由小滚轮67收存蜗卷弹簧65，在百叶窗展开过程中由大滚轮68收存蜗卷弹簧65。钢珠位于单向轴心75与卷绳筒内腔710之间，并同受约于单向轴心75表面上的限制钢珠滑动的轨迹750和卷绳筒内腔710的滑槽共同组成的区域内活动。所述钢珠、单向轴心75及卷绳筒71三者组成为单向离合器；在外力作用下，当百叶窗收起时，卷绳筒71带动钢珠，使钢珠在单向轴心75表面限制钢珠滑动的轨迹750上滑动，此时钢珠能在单向轴心75表面限制钢珠滑动的轨迹750上方向上能自由滑动，起分离作用(即卷绳筒71能自由转动，与单向轴心75脱离)；当百叶窗无外力作用下，下梁2停止在任何位置时，因百叶窗下梁2和叶片4自重的作用，百叶窗有展开的趋势，使卷绳筒71有带动钢珠趋势，此时钢珠不能在单向轴心75表面限制钢珠滑动的轨迹750上能滑动，起结合作用(即卷绳筒71、钢珠及单向轴心75三者一起转动)，也使单向轴心75有转动的趋势，此时夹紧弹簧76的作用下，产生阻力，阻止单向轴心75转动，所以百叶窗能保持静止；在外力作用下，当百叶窗展开时，由于外力作用下，卷绳筒71内钢珠起连接作用，克服夹紧弹簧76产生的阻力后，带动单向轴心75转动，所以百叶窗顺利地展开。
外力作用于下梁2，使百叶窗顺利收起或展开，无外边作用下，使百叶窗任何位置时不展开且又不收起，已满足了的如下条件：1、外力作用下百叶窗收起过程中，卷绳筒71内的钢珠起分离作用，夹紧弹簧76不起作用，此过程中，百叶窗内拉绳3下端所承重量的下梁2重量和叶片4重量已被外力卸掉，在马达蜗卷弹簧65回卷力作用产生的扭力，大于拉绳3自重，将拉绳3卷在卷绳筒71上，所以能顺利地收起百叶窗。2、外力(F)作用下百叶窗展开过程中，卷绳筒71内的钢珠起连接作用，将卷绳筒71、钢珠、单向轴心75三者结合在一起转动，克服夹紧弹簧76产生的阻力(f1)和马达蜗卷弹簧65回卷扭力(f2)后一起转动，将卷在卷绳筒71上拉绳3顺利展开，所以百叶窗能展开；受力满足关系：F+G>f1+f2(G为下梁2重量和叠加在下梁2上叶片4重量的总和)。3、无外力作用下，百叶窗任何位置时不展开且又不收起，但下梁2重量和叠加在下梁2上叶片4重 量作用拉绳3上，百叶窗有展开的趋势，由拉绳3作用在卷绳筒71上，卷绳筒71内的钢珠起连接作用，将卷绳筒71、钢珠、单向轴心75三者结合在一起转动的趋势；在夹紧弹簧76产生的阻力(f1)和马达蜗卷弹簧65回卷扭力(f2)的作用下阻止转动，使它们保持一种平衡状况，所以百叶窗能停止在任何位置；受力满足关系：G＝f1+f2(G为下梁2重量和叠加在下梁2上叶片4重量的总和)。
所述无拉绳百叶窗的工作原理为：
当外力作用向下拉下梁2时百叶窗展开，拉绳3从收绳系统的卷绳齿轮内拉出，此过程中收绳系统内左卷绳齿轮和过渡齿轮为顺时针转动，弹簧齿轮和右卷绳齿轮为逆时针转动，蜗卷弹簧65被弹簧齿轮卷动，不断卷在弹簧齿轮上；因外力加下梁2重量和叠加在下梁2上叶片4的总重量，大于收绳系统内的回弹力和固定座73内产生的拉绳摩擦阻力，所以百叶窗能顺利展开。
当外力作用向上推下梁2时百叶窗收起，在收绳系统内蜗卷弹簧65回弹力的作用下，使左卷绳齿轮和过渡齿轮为逆时针转动，弹簧齿轮和右卷绳齿轮为顺时针转动，致拉绳3不断被收回在拉绳齿轮内；因外力向上推下梁2，作在拉绳3的阻力只有固定座73产生的拉绳摩擦阻力，蜗卷弹簧65回弹力大于固定座73内产生的拉绳摩擦阻力，所以百叶窗能顺利收回。
当百叶窗无外力作用且在完全收起时，百叶窗叶片4完全叠加在下梁2上，下梁2重量加叶片4的总重量小于或等于拉绳3在固定座73内产生的拉绳摩擦阻力加收绳系统内蜗卷弹簧65回弹力，因此百叶窗不会自动下滑。
当百叶窗无外力作用且在完全展开时，百叶窗叶片4完全展开，上梁1重量加拉绳3在固定座73内产生拉绳生产摩擦阻力大于或等于收绳系统内蜗卷弹簧65回弹力，因此百叶窗不会自动反弹收回。
在实施例1中，如图10所示，所述卷绳装置7包括两组固定座73和固定器72以及两组单向离合器、夹紧弹簧76和卷绳筒71，分别位于转轴5的两端。所述叶片4在固定座73上拉绳穿孔730对应的位置穿中孔，即每片叶片4上具有中孔的数目为2。与之相配合，转轴每端的固定座73、固定器72以及单向离合器和夹紧弹簧76与一根拉绳3相配合。即实施例1的百叶窗拉绳3的数目为2根，分别从叶片4的中孔穿过。即每一根拉绳3的一端固定在同侧卷绳筒71靠后盖77一端的端部，拉绳3另一端跨过固定座73侧面铁芯74并穿过，再穿过固定座73底部的拉绳穿孔730后，穿过全部叶片4，最后固定在下梁2上。
实施例2
实施例2提供了一种无拉绳系统的百叶窗，包括上梁1、下梁2、叶片4、拉绳3、卷绳装置7、马达6、转轴5，实施例2中的拉绳3无特殊说明的情况下，均为设置于百叶窗内部的内置拉绳，实施例2不包括游离于百叶窗整体之外的外置拉绳。
卷绳装置7包括固定座73、固定器72、卷绳筒71、后盖77、铁芯74、夹紧弹簧76、单向轴心75和钢珠，所述钢珠、单向轴心75及卷绳筒71组成单向离合器。所述单项离合器控制百叶窗的展开、收起以及在无外力作用下在某一位置保持静止。夹紧弹簧76的一端以紧配合的方式套在单向轴心75上，夹紧弹簧76的另一端在端部设有档脚760，固定座73设置有夹紧弹簧档脚槽，夹紧弹簧76的档脚760卡在固定座73的夹紧弹簧档脚槽内。当百叶窗无外力作用下，百叶窗下梁2和叶片4自重的作用使百叶窗受到向下的力，夹紧弹簧76产生阻力，克服重力作用，阻止单向轴心75转动，保持百叶窗静止。单向轴心75套在卷绳筒71一端的卷绳筒内腔710内，单向轴心75与卷绳筒内腔710间隙配合。单向轴心75表面设有限制钢珠滑动的轨迹750，卷绳筒内腔710设置有滑槽，卷绳筒71的一端含有中心轴711，所述滑槽设置于中心轴711与卷绳筒内腔710的内壁之间，单向轴心75套在卷绳筒71一端的卷绳筒内腔710内并安装于中心轴711上，单向轴心75与卷绳筒内腔710滑槽之间形成的间隙为所述滚珠滚动的空间。卷绳筒71的另一端与后盖77连接。单向轴心75表面设有限制钢珠滑动的轨迹750，卷绳筒内腔710设置有滑槽，所述钢珠位于所述单向轴心75与所述卷绳筒内腔710之间，所述钢珠受约于单向轴心75表面的限制钢珠滑动轨迹750和卷绳筒内腔710的滑槽共同组成的区域内活动。所述钢珠、单向轴心75及卷绳筒71组成单向离合器；在外力作用下，当百叶窗收起时，卷绳筒71带动钢珠，使钢珠在单向轴心75表面限制钢珠滑动的轨迹750上滑动，此时钢珠能在单向轴心75表面限制钢珠滑动的轨迹750上方向上能自由滑动，起分离作用(即卷绳筒71能自由转动，与单向轴心75脱离)；当百叶窗无外力作用下，下梁2停止在任何位置时，因百叶窗下梁2和叶片4自重的作用，百叶窗受到向下的力，使百叶窗有展开的趋势，使卷绳筒71有带动钢珠趋势的向下的力，此时钢珠不能在单向轴心75表面限制钢珠滑动的轨迹750上能滑动，起结合作用(即卷绳筒71、钢珠及单向轴心75三者一起转动)，也使单向轴心75有转动的趋势，此时在夹紧弹簧76的作用下，产生阻力，阻止单向轴心75转动，所以百叶窗能保持静止；在外力作用下，当百叶窗展开时，由于外力作用下，卷绳筒71内钢珠起连接作用，克服夹紧弹簧76产生的阻力后，带动单向轴心75转动，所以百叶窗顺利地展开。所述单向轴心75表面限制钢珠滑动的轨迹750优选为分布于单向 轴心75圆柱面的轨道，所述轨道优选为凹槽或通孔。所述固定座73设置有拉绳穿孔730、梯带穿孔和铁芯固定槽。拉绳穿孔730位于固定座73底部的中心位置，贯穿固定座73底部。所述梯带穿孔位于固定座73底部的拉绳穿孔730的两侧，贯穿固定座73底部。所述梯带穿孔用于梯带8穿过固定座73。所述梯带穿孔优选为2个，用于梯绳或梯带8的穿过。所述梯带穿孔也可用于拉绳3穿过，当拉绳3设置为分布于叶片4两侧的两根拉绳3时，两根拉绳3可分别从两侧梯带穿孔穿过。所述梯带穿孔为长条状孔。长条状的梯带穿孔适用于带状梯带和绳状梯带，并且适用于较宽的梯带也适用于较窄的梯带。固定座73两侧设置有拉绳孔，所述铁芯固定槽设置于固定座73两侧的拉绳孔上。铁芯74安装于铁芯固定槽内，起到阻尼的作用。固定座每一侧的铁芯固定槽及铁芯的数目为两个，铁芯安装于铁芯固定槽内还用于拉绳的缠绕及安装。

拉绳3一端固定在卷绳筒71靠后盖77一侧的端部，拉绳3另一端跨过固定座73侧面铁芯74并穿过，拉绳3缠绕在固定座73上，再穿过固定座73底部的拉绳穿孔730后，穿过全部叶片4，最后固定在下梁2上，卷绳装置7和马达6由转轴5连接，使卷绳筒组间实现同步转动。
如图8所示，在实施例2中，所述卷绳装置7包括两组固定座73和固定器72以及两组单向离合器和夹紧弹簧76，还包括两组卷绳筒71，分别位于转轴5的两端。叶片4在固定座73上梯带穿孔对应的位置冲边槽或冲边孔。每一侧的拉绳3缠绕并固定于同侧的卷绳筒71上。转轴5上每一端的拉绳3穿绳方式为：拉绳3的一端固定在卷绳筒71靠后盖77一端的端部，拉绳3另一端跨过固定座73侧面铁芯74并穿过，再穿过固定座73底部的一侧梯带穿孔后，穿过全部叶片4的一侧边孔，最后固定在下梁2上。另一根拉绳3同样将一端固定在卷绳筒71靠后盖77一端的端部，另一端跨过固定座73侧面铁芯74并穿过，再穿过固定座73底部另一侧的梯带穿孔后，穿过全部叶片4的另一侧边孔，最后固定在下梁2上。即拉绳3从叶片4两侧穿过边孔，经过固定座73梯带穿孔，卷绳筒71内布置二条拉绳3。另一侧的卷绳装置7同样设置有两根拉绳3，完成拉绳3、叶片4、卷绳装置7的组装。
实施例2的拉绳3还可以采用另一种方式，即转轴5每一端的卷绳装置与1根拉绳3配合。拉绳3的一端固定在卷绳筒71靠后盖77一端的端部，另一端跨过固定座73侧面铁芯74并穿过，再穿过固定座73底部的一侧梯带穿孔后，穿过全部叶片4的一侧边孔，随后拉绳3的另一端继续绕过下梁2或者在下梁2上设置能够使拉绳3穿过的通孔，拉绳3另一端穿过下梁2通孔后沿相反方向向上穿过叶片4上另一侧边孔，随后穿过固定座73底部另一侧的梯带穿孔，而后绕过固定座73侧面铁芯74并穿过，最后拉绳3的另一端也固定于卷绳筒71，即一根拉绳3的两端均固定在卷绳筒71上。
实施例3
实施例3与实施例1或2类似，不同的是，实施例3的所述卷绳装置7包括两组固定座73和固定器72以及一组单向离合器、夹紧弹簧76和卷绳筒71，如图9所示，两组固定座73和固定器72分别位于上梁1的两端，单向离合器和夹紧弹簧76与其中一组固定座73和固定器72组装配合。所述叶片4在固定座73上拉绳穿孔730对应的位置穿中孔。每组固定器72与一根拉绳3相配合，每根拉绳3的一端均固定在同一个卷绳筒71靠后盖77一端的端部。即一个卷绳筒71内布置二条拉绳3，两根拉绳3固定并缠绕在卷绳筒71上再分别穿过叶片4的中孔，最后分别固定于下梁2上。拉绳3在固定座73内的绕绳方式与实施例1和实施例2相似。

实施例5
