实施例 1
附图 1-8 示出了本发明的一种收放式窗帘，具体为一种收放式的罗马帘。参照附图 1-8 所示，收放式窗帘包括帘体 100 、带动帘体 100 收放的拉绳 200 及用于窗帘拉绳 200 收放的收放装置。拉绳 200 穿设在帘体 100 中且拉绳 200 的下端和帘体 100 的下端部固定连接、上端部和收放装置固定连接。帘体 100 上端连接有水平延伸的支架 300 ，收放装置包括支架 300 、安装在支架 300 的安装座 400 、同步轮组 1 、传动组件 2 以及绕线组件 3 ，每个同步轮组 1 的左右两侧都分别连接有一个传动组件 2 用于改变传动方向，每个绕线组件 3 分别通过一个传动组件 2 和至少一个同步轮组 1 连接。收放装置具体有如下三种设置方式：
A 、同步轮组 1 为一个，同步轮组 1 左侧的传动组件 2 与一个绕线组件 3 相连接，同步轮组 1 右侧的传动组件 2 与另一个绕线组件 3 相连接，本实施例即采用方式 A ，参见附图 1-6 ；
B 、同步轮组 1 为一个，同步轮组 1 左侧和 / 或右侧的传动组件 2 与至少两个绕线组件 3 相连接；
C 、同步轮组 1 为多个，绕线组件 3 也为多个，各同步轮组 1 左右两侧的传动组件 2 分别与至少一个绕线组件 3 相连接，其中相邻两个同步轮组 1 之间具有至少一个绕线组件 3 。
同步轮组 1 包括至少一个卷簧 12 、至少两个同步轮 11 ，同步轮 11 可转动地设置在安装座 400 上。各所述卷簧 12 的两端分别固定连接于两个同步轮 11 以卷绕于两个同步轮 11 上且在两个同步轮 11 上的卷绕方向相反。各传动组件 2 分别包括相互啮合的第一圆锥齿轮 22 和第二圆锥齿轮 23 ，同步轮组 1 两侧的两个传动组件 2 的第一圆锥齿轮 22 与至少一个同步轮 11 相连接，其中第一圆锥齿轮 22 和第二圆锥齿轮 23 分别可转动地设置在安装座 400 上，且第一圆锥齿轮 22 的转动轴心线和第二圆锥齿轮 23 的转动轴心线相互垂直。参见附图 7 ，各绕线组件 3 分别包括固定设置在帘体 100 上端的固定座 31 、可转动地设于固定座 31 上的绕线轴 32 及传动轴 33 ，传动轴 33 和对应的第二圆锥齿轮 23 相连接，所有绕线组件的传动轴轴心线的延伸方向均一致。绕线轴 32 穿设于传动轴 33 且同轴，绕线轴 32 的外壁沿传动轴 33 的轴心线以逐渐向外的方式倾斜延伸，拉绳 200 的上端部固定连接于绕线轴 32 外径较小的一端，固定座 31 的对应于绕线轴 32 的外径较大的一端处开设有供拉绳 200 穿过的穿线孔 310 。而若为上述方式 B 中，同步轮 11 同一侧若有多个绕线组件 3 ，则这三个绕线组件 3 的传动轴 3 可以是同一个轴，也可以是依次连接的三个轴。
参照附图 5 、 6 所示，同步轮 11 的转动轴心线和传动轴 33 的轴心线相互垂直，传动轴 33 的轴心线沿左右方向延伸。具体到本实施例中，同步轮 11 的转动轴心线和传动轴 33 的轴心线均是水平的，同步轮 11 的转动轴心线沿前后方向延伸。
参照附图 7 所示，固定座 31 上还开设有多个分别处于固定座不同位置的导线孔 311 ，穿线孔 310 位于导向孔 311 和绕线轴 32 的外壁之间，拉绳 200 的上端部依次自其中一个导线孔 311 、穿线孔 310 穿过后连接至绕线轴 32 外径较小的一端部上，拉绳 200 穿在不同的导线孔 311 时具有不同张紧力，可根据帘体重量调整拉绳 200 的张紧力。
传动轴 33 的截面为多边形，具体为正六边形，绕线轴 32 具有与该正六边形相匹配的孔，绕线轴 32 套设于传动轴 33 上。且第二圆锥齿轮 23 上也开设有与该正六边形相匹配的孔，绕线轴 32 的一端部插设在上述第二圆锥齿轮 23 的孔中，第二圆锥齿轮 23 、传动轴 33 、绕线轴 32 共轴。
同步轮 11 和卷簧 12 具有多种组合方式，如：
参见附图 8 、 9 ，同步轮 11 为两个，同步轮 11 的外壁上均设置有一圈轮齿 13 ，两个同步轮 11 通过轮齿 13 相互啮合，一个卷簧 12 卷绕在该两个同步轮 11 上，两个同步轮 11 分别与两个第一圆锥齿轮 22 相连接；
参见附图 10 ，同步轮 11 为两组，每组同步轮 11 包括两个同步轮 11 ，各组同步轮 11 的两个同步轮 11 共轴且沿其轴心线依次排列，各组同步轮 11 中至少一个同步轮 11 的外壁设置有一圈轮齿 13 ，两组同步轮 11 通过轮齿 13 相互啮合，两组同步轮 11 中各有一个同步轮 11 分别与第一个卷簧 12 的两端相连接，且第一个卷簧 12 卷绕在这两个同步轮 11 上，第二个卷簧 12 的两端分别固定连接于两组同步轮 11 的另一个同步轮 11 上并可卷绕在这两个同步轮 11 上，左侧的第一圆锥齿轮 22 与左侧一组同步轮 11 中的一个同步轮 11 相连接，右侧的第一圆锥齿轮 22 与右侧一组同步轮 11 中的一个同步轮 11 相连接；
参见附图 11 ，同步轮 11 为三个，三个同步轮 11 的外壁上均设置有一圈轮齿 13 ，三个同步轮 11 通过轮齿 13 依次啮合，最左侧的同步轮 11 和左侧的第一圆锥齿轮 22 相对应连接，最右侧的同步轮 11 和右侧的第一圆锥齿轮 22 相对应连接，卷簧 12 为两个，其中一个卷簧 12 的两端分别固定连接于中间的同步轮 11 和左侧的同步轮 11 ，另一个卷簧 12 的两端分别固定连接于中间的同步轮 11 和右侧的同步轮 11 ，两个卷簧 12 在中间的同步轮 11 上层叠卷绕；
参见附图 12 ，同步轮 11 为三组，每组同步轮 11 包括两个同步轮 11 ，各组同步轮 11 的两个同步轮 11 共轴且沿其轴心线依次排列，各组同步轮 11 中至少一个同步轮 11 设置有轮齿 13 ，三组同步轮 11 通过轮齿 13 相互啮合，有四个卷簧 12 卷绕于三组同步轮 11 上，卷绕方式同附图 11 所示的方式；
参见附图 13 ，与附图 12 所示的方式的不同之处是有三个卷簧 12 卷绕于该三组同步轮 11 上，其中分别属于其中两组同步轮 11 的两个同步轮 11 上没有卷绕卷簧 12 ；
上述几种方式通过调节同步轮的个数、或卷簧的个数，可以适用于不同重量的帘体上，即，可以调节窗帘帘体的重量。
同步轮 11 和第一圆锥齿轮 22 不同轴，且同步轮 11 的转动轴心线和第一圆锥齿轮的轴心线相互平行，同步轮 11 和第一圆锥齿轮 22 通过圆柱齿轮 21 相连。具体地，同步轮 11 通过轮齿和该圆柱齿轮 22 相互啮合，该圆柱齿轮 21 和第一圆锥齿轮 22 同轴，具体到本实施例中，圆柱齿轮 21 和第一圆锥齿轮 22 一体注塑成型或一体铸造成型。本实施例中，第一圆锥齿轮 22 和第二圆锥齿轮 23 均为 90 度圆锥齿轮。
参见附图 6 、 7 、 9 ，支架 300 的上表面开设有一个沿窗帘左右方向延伸的限位槽 301 ，限位槽 301 的中心线和传动轴 33 的轴心线的延伸方向一致，限位槽 301 为长方形槽，安装座 400 的下表面具有与限位槽 301 的宽度相配合的限位凸起 401 ，固定座 31 的下表面也具有与限位槽 301 的宽度相配合的限位凸起 312 ，安装座 400 和固定座 31 通过螺钉固定连接在支架 300 上，且各限位凸起 401 、 312 正好卡在该限位槽 301 内，使得安装后，所有的安装座 400 和固定座 31 都是沿限位槽 301 的中心线呈线形排列，避免传动轴 33 和传动组件 2 偏移。
该收放式窗帘的工作过程如下：向下拉帘体 100 ，拉绳 200 解卷，带动绕线轴 32 转动，传动轴 33 随之转动，通过传动组件 2 将传动方向转换 90 度，同步轮 11 随之转动，卷簧 12 逐渐自其中一个同步轮 11 上解卷后方向卷绕到两一个同步轮 11 上，发生形变具有弹性力，由于该弹性力不足以克服帘体 100 自身重力，帘体 100 处于拉开位置，如附图 1 、 2 。
向上托或推帘体 100 ，即向帘体 100 施加一个较小的推力，该推力和卷簧 12 弹性力的合力足以克服帘体 100 自身重力，卷簧 12 复位，同步轮 11 反向转动，绕线轴 32 转动将拉绳 200 收卷，帘体 100 随之收卷，如附图 3 、 4 。
由于绕线轴 32 的外壁为斜面，在收卷时，先卷绕在绕线轴 32 上的线匝依次被后卷绕的线匝向前推，单层卷绕，避免了拉绳 200 层叠而发生的常绕或打结，收放顺畅；而且通过传动组件 2 转换传动方向，使得收放装置的布局合理、结构紧凑。
实施例 2
参照附图 14 所示，本实施例与实施例 1 的区别仅在于：同步轮 11 的转动轴心线是竖直的，即沿上下方向延伸。
实施例 3
参照附图 15 所示，本实施例与实施例 1 的区别仅在于：收放装置按上述方式 C 设置，即，同步轮组 1 为多个，绕线组件 3 也为多个，各同步轮组 1 左右两侧的传动组件 2 分别与至少一个绕线组件 3 相连接，其中相邻两个同步轮组 1 之间具有一或多个绕线组件 3 。具体到本实施例中，各同步轮组 1 的左右两侧分别设有一个绕线组件 3 ，其中位于两个同步轮组 1 相对的传动组件 2 之间的绕线组件 3 的传动轴 33 的两端分别与这两个传动组件 2 的第二圆锥齿轮 23 相连接。
上述实施例只为说明本发明的技术构思及特点，是一种优选的实施例，其目的在于熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限定本发明的保护范围。凡根据本发明的精神实质所作的等效变换或修饰，都应涵盖在本发明的保护范围之内。
