如图1-4所示，本实施例在于提供一种凳榻联动装置，包括上连杆1、下连杆2、中间凳榻连杆3、第一前凳榻连杆4、第二前凳榻连杆5、第一连接连杆6、第二连接连杆7、前凳榻支架8和中间凳榻支架9，下连杆2、中间凳榻连杆3与中间凳榻支架9依次铰接，上连杆1、第一前凳榻连杆4与中间凳榻支架9依次铰接，中间凳榻连杆3与上连杆1铰接，第二前凳榻连杆5铰接在第一前凳榻连杆4与前凳榻支架8之间，第一连接连杆6与第二连接连杆7铰接，且第一连接连杆6与第二连接连杆7分别与前凳榻支架8和第一前凳榻连杆4铰接(例如，第一连接连杆6与前凳榻支架8铰接，第二连接连杆7与第一前凳榻连杆4铰接)，中间凳榻支架9与第一连接连杆6铰接；上连杆1或下连杆2能够在驱动力的驱动下转动，并能够带动中间凳榻连杆3、第一前凳榻连杆4、第二前凳榻连杆5、第一连接连杆6、第二连接连杆7、前凳榻支架8及中间凳榻支架9联动，以使凳榻联动装置展开或收拢。
其中，第一前凳榻连杆4的一端与上连杆1铰接，第一前凳榻连杆4的另一端与中间凳榻支架9铰接，第二前凳榻连杆5与第一前凳榻连杆4的铰接点位于第一前凳榻连杆4的两端的铰接点之间。第一连接连杆6的一端与前凳榻支架8铰接，第一连接连杆6的另一端与第二连接连杆7铰接，中间凳榻支架9与第一连接连杆6的铰接点位于第一连接连杆6的两端的铰接点之间。
例如，中间凳榻连杆3的一端与下连杆2通过铰接点a铰接，中间凳榻连杆3的另一端与中间凳榻支架9通过铰接点b铰接，第一前凳榻连杆4的一端与上连杆1通过铰接点c铰接，第一前凳榻连杆4的另一端与中间凳榻支架9通过铰接点d铰接，其中，中间凳榻连杆3与上连杆1还通过铰接点e铰接。第二前凳榻连杆5的一端与第一前凳榻连杆4通过铰接点f铰接，第二前凳榻连 杆5的另一端与前凳榻支架8通过铰接点g铰接。第一连接连杆6的一端与前凳榻支架8通过铰接点h铰接，第一连接连杆6的另一端与第二连接连杆7的一端通过铰接点i铰接，第二连接连杆7的另一端与第一前凳榻连杆4通过铰接点j铰接，铰接点f位于铰接点d与铰接点j之间，其中，中间凳榻支架9的一端与第一连接连杆6通过铰接点k铰接，铰接点k位于铰接点h与铰接点i之间。可以理解的是，凳榻联动装置的多个连杆的铰接点之间可以采用多种铰接形式，示例性地，如销轴、铆钉、轴承或螺栓与螺母组合等；还可以采用家具制造行业中熟知的任何其他适当的连接形式。
在一实施例中，第一前凳榻连杆4、中间凳榻支架9、中间凳榻连杆3与上连杆1形成大四边形，也可以理解为铰接点b、d、c与e之间的连杆形成大四边形结构的四连杆机构，第二前凳榻连杆5、前凳榻支架8、第一连接连杆6与第二连接连杆7形成小四边形，也可以理解为铰接点f、g、h与i之间的连杆形成小四边形结构的四连杆机构。在本实施例中，大四边形结构的主动件为上连杆1，当驱动力通过联动连杆传动到中间凳榻支架9时，相对于中间凳榻支架9来说，第一前凳榻连杆4为主动件，并通过第二连接连杆7与第一连接连杆6联动，从而使得第一连接连杆6变成小四边形结构中的主动件，驱动前凳榻支架8动作，第二前凳榻连杆5为从动件，通过改变第一连接连杆6与第二连接连杆7的长度可以调节第一连接连杆6的驱动力大小，使得凳榻联动装置伸缩更顺畅。采用分体式的第一前凳榻连杆4与第二前凳榻连杆5，第二前凳榻连杆5的长度可以增长，并与第一连接连杆6和第二连接连杆7配合，使得小四边形结构的变形范围更大，同时还不会影响中间凳榻支架9动作，进而可以增加前凳榻支架8与中间凳榻支架9之间的间距，扩大凳榻联动装置的适用范围。在一实施例中，第二前凳榻连杆5与前凳榻支架8的铰接点的高度低于躺垫附接平台91的台面高度。铰接点g的运动轨迹的最高点不会超过躺垫附接平台91的台面，进而不会与躺垫附接平台91互相干扰，保证凳榻联动装置正常动作。
在一实施例中，中间凳榻支架9的一端与第一连接连杆6铰接，中间凳榻支架9的另一端设有躺垫附接平台91。在一实施例中，前凳榻支架8的一端与第二前凳榻连杆5铰接，前凳榻支架8的另一端设有前凳榻垫附接平台81。在本实施例中，中间凳榻支架9与前凳榻支架8均大致为L形结构。在其他实施例中，中间凳榻支架9与前凳榻支架8还可以呈V形或弧形结构。
在一实施例中，分设躺垫附接平台91与前凳榻垫附接平台81，可延长这两个平台的间隙。
在一实施例中，在躺垫附接平台91与前凳榻垫附接平台81外增加软包包装成成品沙发后，躺垫附接平台91与前凳榻垫附接平台81的位置可对应沙发软垫。
在一实施例中，当凳榻联动装置位于展开位置时，躺垫附接平台91与前凳榻垫附接平台81在水平方向上平齐；当凳榻联动装置位于收拢位置时，躺垫附接平台91与前凳榻垫附接平台81在竖直方向上平齐。可以理解的是，水平方向为与水平面平行的方向，则竖直方向为与水平方向垂直的方向。
凳榻结构(ottoman)，也可记为腿部连杆结构。
本实施例还提供了一种架体，如图3-4所示，包括固定组件101、活动连杆组件102和如上述的凳榻联动装置，活动连杆组件102连接在固定组件101上，凳榻联动装置铰接在活动连杆组件102上，即通过将上连杆1及下连杆2的自由端与活动连杆组件102铰接。在本实施例中，凳榻联动装置设置为两个，且大致呈左右对称设置，以提供更稳定的支撑。在其他实施例中，凳榻联动装置可以设置为一个、三个、四个甚至更多，具体使用数量可根据需求进行选择。
例如，当凳榻联动装置位于展开位置时，躺垫附接平台91与前凳榻垫附接平台81在水平方向上平齐，以便于用户躺卧；当凳榻联动装置位于收拢位置时，躺垫附接平台91与前凳榻垫附接平台81在竖直方向上平齐，并抵接在架体100的一侧，以为腿部和脚部提供更大的活动空间。
例如，固定组件101为基座。
在本实施例中，架体100的结构可采用本领域相关技术中常规的架体100，其结构在此不再赘述。
本实施例还提供了一种座椅，包括如上述的架体100。在本实施例中，架体100应用在座椅上，且座椅可以为沙发座椅、高铁座椅或飞机座椅等应用于任意合适场合的座椅。在其他实施例中，座椅还可以为供休息的躺椅等。
本申请实施例公开一种凳榻联动装置，能够增大前凳榻支架与中间凳榻支架间的间距，且前凳榻支架与中间凳榻支架展开的驱动力可以调节。
本申请实施例公开一种架体，通过应用上述凳榻联动装置，使得架体伸缩更顺畅，扩大架体适用范围。
本申请实施例公开一种座椅，通过应用上述架体，提升了使用的舒适感，并扩大了座椅适用范围。
本领域技术人员会理解，本申请不限于这里所述的特定实施例，对本领域技术人员来说能够进行多种明显的变化、重新调整和替代而不会脱离本申请的 保护范围。因此，虽然通过以上实施例对本申请进行了说明，但是本申请不仅仅限于以上实施例，在不脱离本发明构思的情况下，还可以包括更多其他等效实施例。
