Description

一种座椅 技术领域
本发明涉及坐具领域，具体涉及一种座椅。
背景技术
座椅是一种有背垫、有的还有扶手的坐具。目前在办公场所、家庭、商场等固定场所使用的座椅大多是结构固定的，尤其是木制座椅，为了保证其结构的稳定性，通常都是结构固定不变的。而具有活动结构的座椅也基本上是为了升降高度和折叠收纳，例如升降座椅和折叠睡椅。
技术问题
折叠睡椅虽然可以变换状态，但其展开状态下占地面积较大，而且其美观性不足，通常只能作为躺椅使用，并不适用于如会客厅、茶室、办公区等场所，环境适用性较差。此外，目前大多数的座椅不能自如地适配人体位姿，长时间保持一个位姿，身体疲劳度大大增加。
技术解决方案
针对现有座椅大多结构固定，而目前活动结构的座椅占地面积大、适用性差的问题，本发明的目的在于提供一种座椅，其能够灵活适配人体位姿，而且环境适用性好。
为达到上述目的，本发明公开了一种座椅，其包括座椅本体、坐垫和活动连接机构，所述座椅本体包括坐垫支撑结构，所述活动连接机构分别与坐垫和座椅本体连接；所述坐垫可通过活动连接机构在坐垫支撑结构上前后移动。

本发明的最佳实施方式
如图1～5所示，本实施例公开了一种座椅，其包括座椅本体10、坐垫20、 两套活动连接机构30和一弹性件40。在座椅本体10包括第一预装件16、第二预装件17和坐垫支撑结构，其中第一预装件16和第二预装件17相互对称设置，坐垫支撑结构固定于第一预装件16和第二预装件17之间。第一预装件16和第二预装件17均包括扶手162和至少两支腿161，扶手162固定在支腿161上。活动连接机构分别与坐垫20和座椅本体10连接，坐垫20可通过活动连接机构30在坐垫支撑结构上前后移动。坐垫20可以直接与坐垫支撑结构接触，坐垫支撑结构始终对坐垫20起到支撑作用，同时对活动连接结构30也能起到保护作用，避免其受压弯曲影响滑动甚至是损坏。作为替代方式，坐垫20相对坐垫支撑结构悬空，相当于是活动连接机构30将坐垫20顶起来了，而坐垫支撑结构在活动连接机构30失效或损坏时，可以对坐垫20起到支撑保障，保证坐垫20在失去活动连接机构30的支撑时能够得到可靠支撑，避免人体摔倒。
座椅本体10可以由木材或钢材或合金制成，其结构固定，以保证座椅的稳固性。在座椅本体10上还设有一背挡条11和一背垫12，背垫12转动连接在座椅本体10上(在座椅本体10上设置通孔，螺丝穿过通孔后再与背垫12螺纹连接)，作为替代方式，背垫12转动连接在背挡条11上。转动的背垫12可以始终贴合并支撑落座者的背部和腰部，提高舒适度。为了更进一步地适配坐垫30滑动以及保证良好的舒适性，可以将背垫12旋转的角度A限定在0～45°之间。当然，背垫12不可转动也是可以的，比如直接可拆卸地固定(比如螺栓锁紧固定、插接等)在背挡条11上，只是相比与可转动的连接方式，舒适度可能会差一点，但是也可以通过选用较为柔软的背垫12来补足。此外，在坐垫20上可以设置软垫来提高落座舒适度。
活动连接机构30包括滑动连接的第一滑动件31和第二滑动件32，第一滑动件31设置在座椅本体10上，第二滑动件32设置在坐垫20上，在座椅本体10上设有固定第一滑动件31的支架13，通过活动连接机构30的限制与配合，坐垫20可以相对座椅本体10前后移动。作为优选，第一滑动件31选用滑杆或滑轮，第二滑动件32选用与滑杆或滑轮相契合的滑轨，滑杆或滑轮不得脱离滑轨，这样活动连接机构30也能保证坐垫20不脱落。需要说明的是，无论支架13还是坐垫支撑结构都是座椅本体10的一部分，故将第一滑动件31固定在坐垫支撑结构上还是座椅本体10的其它位置，理应纳入本发明的保护范围。
坐垫20前移时，人体容易向前滑动，坐垫20前端翘高有利于防止人体向前滑动，具体地，坐垫20的上表面设计为与水平面呈固定夹角B，B＝0～10°，可以是坐垫20为平板，整个坐垫20与水平面呈0～10°的夹角。或者，也可以通过在坐垫20的前端设置一个拱坡来实现上述目的。
坐垫20放置于坐垫支撑结构的上方，对来自坐垫20的压力起主要支撑作用。坐垫支撑结构包括至少两根支撑杆14，这里以三根支撑杆14为例，其中两根支撑杆14相互平行设置，剩下的一根支撑杆14则垂直连接与这两根平行的支撑杆14之间。三根支撑杆14之间形成一空腔，活动连接机构位于该空腔的下方。活动连接机构设置在空腔的下方可以减少与座椅本体10等的干涉，而且可以被坐垫20遮挡，相当于将活动连接机构隐藏了起来，从而提升座椅整体的美观程度，也能避免落座者的衣服绞入其中，为了提升滑动的流畅度，第一滑动件31和第二滑动件32之间会涂润滑油，这般设置可以避免弄脏衣服。
为了更进一步地对坐垫20的移动范围进行限制，防止使用不当导致坐垫20脱落，在坐垫20底部还设有限位块21，第二滑动件32可以直接与坐垫20连接，也可以与限位块21连接。在座椅本体10上设有与该限位块21配合两根止位杆15，限位块21位于两根止位杆15之间，垂直设置的那根支撑杆14作为止位杆15使用。
弹性件40的一端与座椅本体10连接，另一端与坐垫20连接，弹性件40用于将坐垫20复位，例如坐垫20前移时，落座者离开座位，在弹性件40的作用力下，坐垫20会恢复原始位置，这样也是对座椅的一种保护，可以避免坐垫20保持前移状态时人体突然落座导致摔倒或坐垫20损坏。落座者站起时，在弹性件40的作用下，坐垫20复位，坐垫20不会抵靠在落座者的腿窝处，利于站起，舒适度也更好。弹性件40可以选用弹簧或气弹簧或弹力绳或弹力带，气弹簧作为优选，其具有一定缓冲作用，可以避免座椅快速移动导致的人体摔倒或惊吓，而弹簧、弹力绳或弹力带则能响应速度快，采购者可以选择适宜的弹性件40或者自行替换。当然，不设置弹性件40也是可以的，用户可以自行用手或腿将坐垫20复位。
如图6～7所示，正常落座时，坐垫20保持初始位置，背垫12竖直或微倾斜以提供腰部支撑。当落座者慢慢后靠时，坐垫20缓慢向前滑动，同时背垫12 也跟随转动，使得落座者的腰部始终能够得到有效支撑，而臀部的接触面积能够保持不变，座椅能够适配落座者的位姿，保证落座的舒适性。即使是对于“葛优躺”的坐姿也能起到有效的腰部支撑，维护人体健康。
为了方便运输和现场组装，将座椅本体10除第一预装件16、第二预装件17、背挡条11和背垫12以外的部件都整合在一起，即为坐垫支撑结构。坐垫支撑结构、坐垫20和活动连接机构30按照其连接关系装配组成第三预装件50。故在运输时，座椅被分解为以下五部分进行运输：第一预装件16、第二预装件17、背挡条11、背垫12和第三预装件50。座椅分解后占用空间更小，利于打包运输。
在座椅组装时，通过螺丝61、螺母62、内螺纹套63、螺杆64、榫65、垫块66等连接件，即可快速地组装出座椅，具体组装顺序参见图8～15。
实施例二：
本实施例与实施例一相比，区别在于：将第一滑动件31与坐垫20固定，而第二滑动件32与座椅本体10固定。与实施例一相比，两者原理及作用相似，本实施例中不再赘述。
实施例三：
如图16所示，本实施例与实施例一相比，区别在于：活动连接机构30直接选用滑轮，滑轮分别设置在坐垫20的两侧，可以在坐垫20两侧并排设置多组滑轮以提高滑行的流畅度。在两根平行设置的支撑杆14上设有与滑轮配合的限位槽141。另外，因为活动连接机构30改变，取消支架13。这种设置使得整体的结构更加简单，利于成本的控制。
实施例四：
本实施例与实施例三相比，区别在于：滑轮分别设置在两根平行设置的支撑杆14上，在坐垫20的两侧设有与滑轮配合的限位槽141。与实施例三相比，两者原理及作用相似。
工业实用性
综上，本发明所述的座椅，其座椅本体包括了坐垫支撑结构，其为坐垫提供支撑力，坐垫通过活动连接机构在坐垫支撑结构上前后滑动，落座者抵靠在座椅本体上的力会同样作用到坐垫上，使坐垫滑动以适配落座者当前的位姿，从而提高落座者的舒适度，落座者也可以自行调整坐垫位置来找寻一个较为舒适的坐姿， 坐垫向前滑动相当于坐垫向前延伸，还能有助于落座者伸展身体，也适宜落座者后靠休息小憩。而且本发明相比于折叠躺椅，其活动幅度小，占用地小，而且结构简单、精巧，造价低，环境适用性更好。另外，本发明座椅可以分解为第一预装件、第二预装件和第三预装件，以利于运输，而且装配简单。本发明所述的座椅具有工业实用性。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
