Description
本发明涉及座椅设计制造领域，具体涉及座椅的搁脚设计。
座椅是日常生活工作中用途非常广泛的一种家具，通常包含底座、靠背、支撑结构、扶手等部件。如公开号为CN201620974125.9的中国专利文件公开了一种座椅，人们在使用过程中能得到来自背部、腰部、臀部、扶手这四个位置的支撑，增加人体的舒适性。
随着人们生活水平的提高，人们对座椅的需求也变得更为多样性。有厂商开始研发和生产具备搁脚装置的座椅。搁脚装置往往和座椅主体连接，用户将双脚放置在搁脚装置上，抬高脚部，提升坐姿状态下的舒适性。如授权公开号为CN
206949927 U的中国专利文件公开了一种办公椅，其在椅座下方设置有搁脚机构，并且，该种搁脚机构采用了抽拉式的设计方式，可相对于椅座在前后方向滑动，一方面做到了适应不同身高的用户的搁脚需求，另一方面可将搁脚机构收纳在椅座对应的槽体中，便于收纳和美观。
然而，该种结构的座椅在实际使用中依然存在着一定的缺陷，一方面，搁脚机构在收纳的过程中存在着收纳不顺利的问题，搁脚装置很难进入对应的座椅下方的容纳槽。在实际使用中，往往需要用户蹲下，用手且较为用力地将搁脚机构送入容纳槽，不仅费时费力，且用户的手部和膝部也容易弄脏。另一方面，搁脚虽然能在长度方向上滑行调节，但是由于不同的用户其体重、脚型都不同，单一的搁脚支撑效果有限。
本发明的目的在于克服现有技术的不足，提供一种适用于座椅的搁脚装置和一种座椅，不仅提升对用户脚部的支撑效果，增加对不同用户的通用性，且增加收纳过程的便利性和顺畅性。
本发明的上述技术目的是通过以下技术方案得以实现的：一种适用于座椅的搁脚装置，包含椅座、与椅座滑动连接的滑动管和安装在滑动管上的搁脚总成，搁脚总成为两套，分别单独与滑动管连接，每套搁脚总成均包含固定座、摆动座和单板；固定座与滑动管连接，摆动座与滑动管转动连接且在竖直方向上翻转，单板包含与摆动座固定连接的基盒和与基盒滑动连接的滑动板，两个滑动板的滑动方向为座椅的宽度方向。
一方面，在我方技术方案中，不采用一体式搁脚，而是采用分体式的两套搁脚总成，每套搁脚总成中均包含有一个滑动板。两个滑动板可以滑动，且滑动方向为座椅的宽度方向。这就使得两个滑动板可以彼此靠近和远离，从而整个搁脚区域的宽度实际可调，满足了不同用户、不同姿势的搁脚需求，提升了搁脚的舒适性和通用性。
另一方面，现有产品，刚使用时，由于搁脚部件和椅座下方的收纳区域，如收纳盒、收纳槽、收纳框较为贴合，收进容易。然而随着使用时间的增加，滑动管和/或搁脚部件都会形变，与收纳区域的贴合度降低，收进时容易碰撞、干涉，增加了收进的难度。而在本案中，单板作为搁脚的主体部件可以在竖直方向上翻转，这就带来了两个技术效果。其一，即使在收进收纳时存在形变干涉，也可以通过单板的翻转来使得优化收进的角度，避免与周边的部件例如收纳框、收纳盒的壁发生碰撞，收纳顺利。其二，使用时，单板为了人体舒适度，往往与水平面有着近30°-60°的夹角，而在收纳时，单板可翻转到近乎水平，从而减小收纳区域的体积。
作为本发明的优选，摆动座包含连接座和位于连接座侧端的转动柱，固定座侧面开设有供转动柱进入的配合孔一。
作为本发明的优选，摆动座连接有连接件，连接件上连接有限位栓，固定座包含用于抵触限位栓从而对摆动座的翻转角度进行限位的限位瓣。
作为本发明的优选，连接件包含表面平整的固定平面，限位栓安装在固定平面上。
作为本发明的优选，摆动座通过固定栓与连接件连接，固定栓安装在固定平面上。
作为本发明的优选，两个摆动座连接在一个连接件上。
作为本发明的优选， 连接件上套设有隔套，隔套位于两个固定座之间。
作为本发明的优选，隔套包含主筒和在主筒的两个侧端伸出的辅助柱，固定座上设有供辅助柱进入的配合孔二。
作为本发明的优选，基盒上设有嵌入件，滑动板包含供嵌入件进入从而锁定滑动板相对基盒相对位置的配合孔，配合孔为多个，开设在调节条上。
作为本发明的优选，嵌入件包含弹性件和顶珠，弹性件一端与基盒连接，另一端与顶珠连接。
作为本发明的优选，基盒包含在高度方向上排布的上盒和下盒，滑动板位于上盒和下盒之间，上盒和下盒通过连接柱连接，滑动板上开设有滑动槽，连接柱在滑动槽中移动。
一种座椅，包含靠背和椅脚，适用于座椅的搁脚装置，靠背和椅座连接，椅脚安装在椅座的底面上。
综上所述，本发明具有如下有益效果：
1、采用分体式的两套搁脚总成，每套搁脚总成中均包含有一个滑动板。两个滑动板可以彼此靠近和远离，从而整个搁脚区域的宽度实际可调，满足了不同用户、不同姿势的搁脚需求，提升了搁脚的舒适性和通用性。
2、单板作为搁脚的主体部件可以在竖直方向上翻转，避免与周边的部件例如收纳框、收纳盒的壁发生碰撞，收纳顺利。
3、收纳时，单板可翻转到近乎水平，从而减小收纳区域的体积。
4、连接件的存在，用户在操作一个单板翻转时，自然会带动另一个单板的同步翻转，提升操作便利性。
5、采用了“同步翻转、中段加强”的翻转设计，且由于六角轴的存在，多个部件能保持良好的同轴度，翻转动作简易、顺畅、稳定度高。
6、隔套的存在避免滑动管的形变，强化整个结构的稳定度。
7、限位栓与抵触瓣抵触，从而使得单板的翻转角度在两个幅度上被限位。这两个限位角度即可对应为单板在使用过程中的角度和在收纳状态下的角度，提升实用性。
8、固定平面的存在，一方面使得限位栓的安装过程变得更为容易，另一方面使得两个限位栓的安装角度变得更为精确和可控，从而使得两个固定座对两个限位栓7的限位角度是一致和稳定的。
9、连接座和隔套一左一右紧贴固定座，使得滑动管不仅不易向内倾斜，也不易向外倾斜。
10、基盒采用了上下两层的设计，包含上盒和下盒，而滑动板则在上盒和下盒之间。这样的三层设计不仅能起到使得滑动板的滑动更为顺利稳定，且滑动板作为一个主要的承力部件，拥有更好的支撑稳定性。
11、嵌入件采用了弹性顶珠的设计，顶珠的球体圆弧设计也可以使得缩回顺畅。

以下结合附图对本发明作进一步详细说明。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
实施例1，如图1所示，一种适用于座椅的搁脚装置，包含椅座91，椅座91的下表面滑动安装有滑动管92，其前端安装有搁脚总成1。在用户使用时，用户可操作滑动管92划出，将双脚搁置在搁脚总成1上休息，提升舒适性。当不使用时，可操作滑动管92回滑。滑动管92可以为伸缩管设计。在椅座91的下表面往往设有收纳区域，如设置一个收纳框，搁脚总成1在回滑后自然进入收纳框完成收纳。以上部分，如椅座的结构、滑动管92的结构、收纳框的结构，与现有技术相同，本案可不做修改。
在本实施例中，滑动管92可以为两个，每个滑动管92均单独连接一个搁脚总成1。两个搁脚总成1的结构相同，布置方式左右对称布置。
如图2所示，每个搁脚总成1均包含一个固定座3，固定座3与滑动管92固定连接，在下文叙述的单板5的移动中，固定座3可视为一个不动件。
如图3和图4所示，在翻转过程中，翻转的部件是隔套2、单板5、摆动座4这三个部件，而固定座3是不翻转的。具体的，摆动座4包含连接座41和转动柱42。其中，连接座41用于连接单板5，而转动柱42即为这个翻转动作的旋转轴。固定座3的侧面开设有配合孔一，转动柱42卡入配合孔一，并且在用户的操作下发生相对转动，从而带动整个翻转动作。
在本案中，采用了“同步翻转、中段加强”的翻转设计。具体的，存在连接件6，在本实施例中，采用一个多边形轴，例如六角轴。如图3所示，一个六角轴穿过两个摆动座4、穿过两个固定座3、穿过一个隔套2，固定座3的开孔可以不与六角轴配合，例如开孔尺寸大于六角轴的尺寸，两者之间就不会发生旋转传动。而两个摆动座4和一个隔套2的开孔与六角轴在尺寸和形状上贴合，从而使得这几个部件中存在旋转传动。用户在操作一个单板5翻转时，自然会带动另一个单板5的同步翻转。而中段，本案增设了一个隔套2，隔套2包含主筒21，其左右两端均伸出一个辅助柱22。而固定座3开设有配合孔二，辅助柱22卡入配合孔二，故，在翻转动作中，中间位置的两个辅助柱22，两侧位置的两个转动柱42，共同作为翻转动作的转动轴，且由于六角轴的存在，这四个部件能保持良好的同轴度，翻转动作简易、顺畅、稳定度高。
隔套2的作用有二，作用一是上文所述的“同步翻转、中段加强”，另一个作用是强化整个结构的稳定度，避免形变。具体的，滑动管92具备一定的长度。其一端是连接在椅座91上，这一端的位置可视为固定的，可靠的。而另一端是去与搁脚总成1连接的，在实际使用中，有可能由于用户的脚部动作而使得两个搁脚总成1相互靠近。而这份相互靠近就会使得滑动管92倾斜、弯曲，长时间后不利于设备的使用寿命。而隔套2位于两个固定座3之间，滑动管92和固定座3固定连接，这就使得两个滑动管92的末端间距被限定，不存在由于相互靠近造成的滑动管92的弯曲。
此外，在这个过程中，对于单板5的翻转角度，进行了限位设计。具体的，连接件6上存在至少一个固定平面61，在本实施例中，由于是六角轴，就存在六个固定平面61。在固定片面61上安装有限位栓7。如图4所示，限位栓7的位置在固定座3的内腔中，固定座3的内腔中设有两个抵触瓣（图中未画出），在翻转过程中，限位栓就会与抵触瓣抵触，从而使得单板5的翻转角度在两个幅度上被限位。而在实际运用中，这两个限位角度即可为单板5在使用过程中的角度和在收纳状态下的角度。
本案中由于是两套搁脚总成1，故存在两个限位栓7。固定平面61的存在，一方面使得限位栓7的安装过程变得更为容易，另一方面使得两个限位栓7的安装角度变得更为精确和可控，从而使得两个固定座3对两个限位栓7的限位角度是一致的，是稳定的。
如图3和图4所示，摆动座4包含连接座41，连接座41一方面作为一个连接介质和单板5连接，另一方面也与连接件6连接。具体的，连接座41通过固定栓8连接在连接件6上。连接座41和隔套2一左一右紧贴固定座3，使得滑动管92不仅不易向内倾斜，也不易向外倾斜。
单板5采用了“两部三层”的设计方案，具体的，如图5所示，单板5包含了两个部分，分别是基盒51和滑动板52。两者之间存在座椅宽度方向上的相对滑动，基盒51和连接座41连接，在滑动的这个动作中，可视为一个不动件。滑动板52和基盒51相对滑动，其在滑动动作中，视为一个动件，且是用户脚部搁置的主要部件。基盒51采用了上下两层的设计，包含上盒和下盒，而滑动板52则在上盒和下盒之间。这样的三层设计不仅能起到使得滑动板52的滑动更为顺利稳定，且滑动板52作为一个主要的承力部件，拥有更好的支撑稳定性。
上盒和下盒之间通过连接柱进行连接，在滑动板52中开设有与之匹配的滑动槽523。在用户滑动滑动板52时，连接柱就在滑动槽523中移动。滑动过程的位置固定通过嵌入件来实现。具体的，嵌入件包含弹性件和顶珠，弹性件一端安装在基盒51上，一端连接在顶珠上。而滑动板52上包含一条调节条521，其上不同位置设有多个配合孔522。弹性件给顶珠施加一个顶出的弹力，顶珠的一部分卡在基盒51上，一部分卡进配合孔522中，完成滑动板52和基盒51的相对固定。需要滑动板52滑出时，用户只要稍微施加力，克服弹性件的弹力，顶珠缩回，即可实现相对滑动，而顶珠的球体圆弧设计也可以使得缩回顺畅。
一种座椅，包含靠背和椅脚，包含上文所述的搁脚装置，靠背和椅座91连接，椅脚安装在椅座91的底面上。
