Description

自适应地面环境的家具支脚 技术领域
本发明涉及室内家具和室外家具技术领域的一种自适应地面环境的家具支脚。
背景技术
现在，日常生活用的睡觉床的床脚与床挺(也叫床添、床听，在床面的两侧通过床桓固定连接，床桓也叫床横)的连接都是固定硬连接，由于床脚之间的加工误差和地面的不完全平整，导致一张床的几个床脚的下端不能够与地面完全接触落实，因此，在安床时，经常采用不同厚度的片来把与地面之间有间隙的床脚垫起来。为了解决床脚之间的加工误差和地面的不完全平整的问题，市场上出现了落地床，落地床的床挺的下面直接与地面接触而采用整体承载的方式，基本上解决了脚之间的加工误差和地面的不完全平整的问题；但因为落地床的床挺把床下面的地面全部罩住，床下面的湿气挥发不出来，导致寒冷季节睡在床上感觉床很冰冷。并且，传统的床不能根据使用者感觉最舒适的卧姿来调整床面的倾斜度。
目前市场上的座椅有三脚座椅、单脚座椅、四脚座椅，也有五脚的座椅和六脚的座椅，这些座椅中有能够升降的，也有不能升降的。能够升降的座椅多以单脚升降的座椅为主，也有多脚升降的座椅。一、单脚升降的座椅，(一)有采用转动齿轮单向拨动支撑内柱上的齿条向上滑动并用舌齿锁住转动齿轮不回转来使支撑内柱不下滑来进行升高，采用让舌齿离开转动齿轮而使自动齿轮回转来使支撑内柱下降；(二)也有采用人工液压泵或电动液压泵带动液压缸伸长，采用回压螺钉泄压来降低；(三)也有采用螺杆和螺套配合，通过转动螺杆来让椅脚伸长和缩短。二、多脚升降的座椅，(一)有采用滑动套接式的，通过内套镶嵌在外套内的方式形成套接式的配合，通过拉动外套与内套来伸长，通过推动外套向内套移动来缩短，并通过卡销插入卡孔中锁定伸长或缩短后的椅脚的长度不发生改变；(二)也有采用固定套接式的，通过固定的外套套在固定的内套下端来使椅脚伸长，通过拆除外套来缩短椅脚；(三)也有采用螺杆和螺套配合，通过转动螺杆来让椅脚伸长和缩短。但这些座椅的椅脚的伸长和缩短并不能够满足座椅在野外倾斜的坡面和凹凸不平的地面上安放平稳落实，也不能让座椅根据使用者喜欢的坐姿来调整座椅的倾斜角度和座靠姿势。
目前，市场上能够调整餐桌的支撑脚的高度的有：采用更换横向凸块在横向凹卡位中的位置来调整支撑脚的高度、采用滑筒式的支撑脚来调整支撑脚高度的餐桌、采用电动调整支撑脚的高度三种。一、采用更换横向凸块在横向凹卡位中的位置来调整支撑脚的高度的餐桌：支撑脚采用带有横向凹卡位的竖向凹槽与带有横向凸块的竖向柱配合，竖向柱在竖向凹槽中、横向凸块在横向凹卡位上锁定支撑脚的高度，调整高度时，横向凸块更换到更高或更低的横向凹卡位中，来实现调整支撑脚的高度，由于横向凹卡位之间有间隙，导致支撑脚的下端不能平稳的安置在倾斜的地面和凹凸不平的地面上来保证餐桌的桌面在水平的面上。二、 采用滑筒式的支撑脚来调整支撑脚高度的餐桌：滑筒式的支撑脚的外筒和内筒上设有卡孔，通过卡销插入外筒和内筒的卡孔中进行固定，通过调整外筒与内筒上的卡孔的位置来进行调整支撑脚的高度，由于卡孔之间有一定的距离，导致支撑脚的下端不能平稳的安置在倾斜的地面和凹凸不平的地面上来保证餐桌的桌面在水平的面上。三、采用电动调整支撑脚的高度：采用电动的方式来让支撑脚伸长和缩短，但在野外没有电线的铺架和电源的供应，而导致不能在野外使用。
随着社会的进步和发展，热爱野外悠闲生活的人越来越多，而在野外舒适的睡觉首先需要有适应倾斜的地面和凹凸不平的地面上安放平稳落实的床，在野外舒适的休闲首先需要有适应倾斜的地面和凹凸不平的地面上安放平稳落实的座椅；但传统的床和座椅的四只脚的高度是固定不变的，根本不能改变床挺的高度来适应倾斜的地面和凹凸不平的地面上；因此，传统的床和座椅根本不能用于野外休息和休闲生活使用。
随着社会的进步和对物质生活的享受的要求越来越高，人们对睡觉用的床的舒适度和对休闲的座椅的舒适度的要求越来越高。由于现在睡觉用的床的四只脚的高度是固定不变的，有的人为了满足自己的舒适要求，将部分床脚垫高来实现床的高低斜度来满足自己睡觉舒适度；也由于座椅的四只脚的高度是固定不变的，有的人为了满足自己的舒适要求，将部分椅脚垫高来实现床的高低斜度来满足自己舒适的坐姿；但将部分床脚垫高后或将比分椅脚垫高后，床脚与床挺不垂直而产生了倾斜度而使床脚在与床挺的连接处容易折断而容易发生安全事故，椅脚与座椅架不垂直而产生了倾斜度而使椅脚在与座椅架的连接处容易折断而容易发生安全事故。
随着社会的进步和物质生活越来越丰富以及交通的快速发展，热爱旅游的人越来越多，自己驾车旅游又成为了旅游的重要方式。自己驾车旅游出行过程中，野外山地用餐基本上是在倾斜的山坡上和凹凸不平的山坡上。而，传统的收折餐桌打开为桌子时几只脚的下端要求基本在同一个平面上，才能让餐桌安放得稳妥；传统的固定脚桌子的几只脚的下端也是要求基本在同一个平面上，才能让餐桌安放得稳妥；同时，要想使桌面上摆放的盘碗中的汤水不溢出，餐桌的桌面必要在水平的面上。而传统用餐的收折餐桌和传统的固定脚餐桌在斜坡上摆放时桌面是倾斜的，导致盛装食物的盘碗在倾斜的桌面上容易让盘碗中的汤水因倾斜溢出，继而导致传统用餐的收折餐桌安放在斜坡上不能摆放盛装食物的盘碗。因此，在自己驾车旅游出行过程中，人们在凹凸不平和倾斜山地用餐时，基本上都是采用在倾斜的地面上铺一张塑料膜来摆放餐具和食物，用餐的人基本上都是尊在地上吃饭，没有优雅感，又极为不方便。
为了让家具的支脚能够适应不同的地面落实，让倾斜的地面和凹凸不同的地面上摆放的桌子的桌面基本达到水平、摆放的座椅能够根据使用者的舒适程度来调整坐姿和靠姿、摆放的床能够根据使用者的舒适程度来调整卧姿和躺姿，几个大学生校友经过长期的研究，设 计出了能够让支脚能够随意伸长和随意压缩缩短的、能够快速锁定伸长和缩短后的支脚的长度的、能够安放在倾斜的地面和凹凸不平的地面上落实平稳的自适应地面环境的家具支脚。
作为几个大学生校友的老师，目睹了几个大学生从研究复杂的技术结构开始出发到技术结构的最为简单的最后的成功，历经了三年之久的锲而不舍和坚忍不拔的研发历程，这也是人们常说的所谓的大道至简的一个过程；作为一个致力于力的转换研究了三十多年的大学老师深知，研究出复杂的技术结构不难，难的是把复杂的技术结构变成简单的技术结构，只有把复杂的技术结构变成简单的技术结构才能算是真正的大道至简，在这一生的教书生涯中能有这样具有创新能力和研发能力的学生也很欣慰和自豪。
