Description

一种椅脚 技术领域
本发明涉及一种椅脚，属于转椅配件技术领域。
 背景技术
为了方便椅子的运输，通常将椅子设计为可拆卸的结构。这样做显著提高了存储和运输的效率。而现有技术通常将椅子的五星脚制作成一个整体，这个整体相对于椅子的基体可快速拆装。但这个整体在存储和运输中仍然占据了较大的空间，故现有技术进一步地提出了一种可拆装的椅脚。如授权公告号为CN 103735069 B的中国发明专利，公开了一种可拆装椅脚。它包括脚座、脚臂和扣件；脚座设有用于安装扣件的中心孔，脚座沿中心孔圆周阵列设有若干个用于安装脚臂的插孔，扣件设有用于连接脚臂和脚座的固定销，扣件内设有用于安装椅座支撑件的连接口，扣件位于脚座内的一端设有若干个圆周阵列分布的挡片。实施上述技术方案，可在将五星椅脚做成可拆卸的同时，装配完成的后五星椅脚还具有结构强度好的优点。
 技术问题
可以预见的是，上述方案提供了一种思路，但这种思路显然不是唯一的。
值得说明的第一点是，上述方案具有较为明显的缺点，而这个缺点在当时并不突显。随着人们审美意识的提高，外观精美的椅子在市场上更受欢迎。外观精美是个较为抽象的概念，但不可否认的一点是，如果椅脚的整体化程度高，就越容易被认为是外观精美的。拿上述专利来举例说明，由于上述方案中的椅脚在装配完成后仍然能够明显地看出脚座、脚臂和扣件之间具有装配缝隙，并且从视觉效果来看，扣件凸显在脚座上显然对于椅脚的外观具有负面影响。
值得说明的第二点是，消费者更加倾向于购买具有金属质感的椅脚，如不锈钢材质的或者铝合金材质的。金属材质的椅脚不仅具有更好的外观，而且还具有更高的连接强度。然而，一个不可忽略的问题是，金属材质的椅脚具有更大的质量，不利于运输。另外，金属材质的椅脚使用时会产生“吱嘎”声而令人心烦。
 技术解决方案
本发明要解决上述问题，从而提供一种外观精美、结构强度高并且使用时不会产生“吱嘎”声的椅脚。
本发明解决上述问题的技术方案如下：
一种椅脚，包括基座、设置在基座中间的气弹簧安装座以及连接在所述基座上的多个支撑脚，所述支撑脚远离所述基座的一端设置有轮脚安装座；所述的基座、气弹簧安装座、支撑脚和轮脚安装座均由上壳部和下壳部组合而成；所述的上壳部和下壳部之间固定连接；
所述上壳部的基座、气弹簧安装座、支撑脚和轮脚安装座一体连接；
所述下壳部的基座、气弹簧安装座、支撑脚和轮脚安装座一体连接；
下壳部的轮脚安装座设有用于安装轮脚的安装孔；
所述的上壳部为金属；
所述的下壳部为塑料。
作为优选，所述的上壳部和下壳部之间卡接。
作为优选，所述的上壳部至少部分地包覆所述下壳部。
作为优选，所述下壳部的轮脚安装座为空心管状并通过其底部与所述的下壳部的支撑脚一体连接；所述上壳部的轮脚安装座为套筒状，并通过其上部与所述上壳部的支撑脚一体连接；所述上壳部的轮脚安装座套装在所述下壳部的轮脚安装座上并将其包覆。
作为优选，所述上壳部的基座包覆所述下壳部的基座。
作为优选，所述上壳部的气弹簧安装座部分地插装在所述下壳部的气弹簧安装座内。
作为优选，所述上壳部的支撑脚包覆所述下壳部的支撑脚。
作为优选，所述的上壳部和下壳部之间通过卡条和卡槽卡接配合；所述的卡条设置在上壳部，卡槽设置在下壳部；或者卡条设置在下壳部，卡槽设置在上壳部。
作为优选，还包括用于提高所述卡条和卡槽之间的卡接配合强度的弹性卡子，并且所述弹性卡子的内侧面与所述的卡条弹性抵压连接，所述弹性卡子的外侧面与所述的卡槽弹性抵压连接。
作为优选，所述的弹性卡子由金属材料制成，包括卡子本体、设置在卡子本体上的内向弹性片和外向弹性片；所述内向弹性片斜向上设置，所述外向弹性片斜向下设置。
本发明上述技术方案中，上和下的位置关系是基于卡条设定的。因为在装配的时候，预先把弹性卡子卡装在卡条上，而通常卡条是设置在金属材质的上壳部的；因此，在椅脚正确摆放时，卡条朝下设置，内向弹性片由于要卡接在卡条上，故需要从下部向上卡套在所述的卡条上，在此状态下，内向弹性片斜向上设置，外向弹性片斜向下设置。如果卡条是设置在塑料材质的下壳部的，那么，弹性卡子需换向安装，此时内向弹性片斜向下设置，所述外向弹性片斜向上设置。实际上，上述两种情况中的弹性卡子结构并没有发生变化，上和下的关系仅仅是基于弹性卡子本身的安装方向来描述的。
作为优选，所述的内向弹性片包括设置在卡子本体一端的第一内向弹性片、设置在卡子本体另一端的第二内向弹性片和设置在卡子本体中部的第三内向弹性片；所述外向弹性片包括设置在卡子本体一端的第一外向弹性片和设置在卡子本体另一端的第二外向弹性片。
作为优选，所述第一内向弹性片和第二内向弹性片相对于卡子本体的倾斜角度为45°~75°；所述第三内向弹性片相对于卡子本体的倾斜角度为10°~30°。
作为优选，还包括气弹簧保护套，所述气弹簧保护套的顶部与所述的气弹簧安装座的底部卡接。
 有益效果
综上所述，本发明具有以下有益效果：
本发明将椅脚设计为金属材质的上壳部和塑料材料的下壳部，上壳部和下壳部配合连接，从视觉效果上看，本发明为金属材质，具有精美的外观；从整体结构上看，本发明金属和塑料的复合结构，相对于纯金属材质，有效地降低了椅脚的重量；从力学性能上看，本发明在正确安装后，椅子的重量主要有金属材质部分直接承担，但同时由于材料复合的关系，下壳部也能间接地分担椅子的重量；从使用效果上看，由于椅子的轮脚部分是安装在位于下壳部的呈空心管状的轮脚安装座中，因此，椅子在使用时，轮脚不会与金属部分发生直接接触，因此可避免产生令人烦躁的“嘎吱”声；从产品局部力学特性上看，尽管与轮脚部分直接接触的是下壳体的轮脚安装座，塑料的力学性能普遍低于金属材质，但由于本发明的上壳体是包覆在下壳体上的，尤其是轮脚安装座部分，上壳部的轮脚安装座套装在下壳部的轮脚安装座上并将其包覆，故在力学性能上，当塑料材质的下壳部的轮脚安装座受到多个方向的载荷时，尤其是轮脚安装轴安装后自然的产生的朝向四周的挤压应力并且因为椅子的负载产生的多个方向的压应力时，如无上壳体包覆则塑料部分易胀裂；金属材质的上壳体的轮脚安装座能够对塑料材质的下壳体的轮脚安装座提供抵消该载荷的对应力。此外，由于金属材质包覆在外，当椅子在使用中受到撞击时，尤其是轮脚安装座的部位最容易受到撞击，本发明中，由于此部位是金属材质包覆在外，故能够对整体结构产生良好的保护作用。
