Description

多功能平衡椅 技术领域
本发明涉及一种平衡椅，尤其涉及一种多功能平衡椅。
背景技术
传统平衡椅，包括支腿架、固设在支腿架上的靠背、固设在支腿架上的椅座部分和固设在支腿架上的跪垫部分，该平衡椅只有单一功能，因此存在待改进之处。
针对上述不足，有人提出了解决方案，如中国专利数据库公告的CN2390484Y，一种可变平衡椅，包括坐板、支架及靠背，支架的后坐板调节套杆与后支撑杆采用可实现升降的连接方式连接，坐板与支架采用定位嵌入式连接方式连接，膝腿受力垫固定在与人体就坐时膝腿部相对应的支架处。该可变平衡椅虽可在座椅状态和平衡椅之间变化，但因在作为座椅状态使用时，一方面，膝腿受力垫的存在会干涉坐者腿部的放置，导致坐者产生不舒适感，另一方面，坐板面积过小，也会导致坐者产生不舒适感。
发明内容

如图2所示，该跪垫部分30处于对齐椅座部分20的位置，即，此时本发明多功能平衡椅处于座椅状态，构成市场上常见的椅凳，该椅凳的坐部即包含了椅座部分且还包含了跪垫部分，增大坐部面积，又避免跪垫干涉坐者腿部放置。如图1所示，该跪垫部分30处于构成平衡椅跪垫的位置，即，此时平衡椅的椅座部分20倾斜布置且倾斜面朝前，该跪垫部分30倾斜布置且倾斜面朝后，坐者坐靠在椅座部分20之上，两腿跪撑在跪垫部分30之上，此时本发明多功能平衡椅处于平衡椅状态，构成市场上常见的平衡椅。
本实施例之中，还包括固接在支撑部分10的支架40，该支架40呈圆心位于椅座部分20转动轴线的弧线上。该支架40上设有能沿支架40相对滑动的滑座41，该椅座部分20连接有能相对椅座部分20前后滑动的第一滑杆21，该第一滑杆21固接或转动连接在滑座41上，通过滑座41相对支架40的滑动能够带动椅座部分20相对支撑部分10转动。还包括靠背50和扶手60；该靠背50装接在支架40上，该扶手60装接在支架40上，该装接如固接或转动连接。
本实施例之中，该连接机构包括同步连杆31，该同步连杆31一端能转动连接在跪垫部分30，另一端连接在支撑部分10且能相对支撑部分10转动。该椅座部分20前中部设呈凸出的凸出部分22，该跪垫部分30后中部凹设呈内凹的内凹部分32，处于对齐椅座部分20的位置的跪垫部分30的内凹部分32和凸出部分22凹凸适配，两者互为榫合构成完整椅座。最好，该跪垫部分30和椅座部分20的转动轴线穿过凸出部分22前部和内凹部分32后部。该跪垫部分30前部之下固设有连杆支撑臂33；该同步连杆31一端能转动连接在跪垫部分30的连杆支撑臂33末端，另一端连接在支撑部分10且能相对支撑部分10转动。该另一端的连接例如是：直接转动连接，或者， 如支撑部分开设有滑槽，另配设枢轴和调节机构，同步连杆31另一端转动连接在枢轴；枢轴活动适配连接滑槽，调节机构连接枢轴和支撑部分以能调节枢轴相对滑槽的位置，通过调节机构和滑槽以能改变另一端转动连接轴线的相对位置。
一具体结构中：该支撑部分10包括一支撑架11和一固接在支撑架11上的底盘12；该支撑架11如图1或图2所述的带滚轮椅腿座，或，图4和图5的人字腿等；该底盘12包括盘体121和固接在盘体121前下部的悬臂122，该椅座部分20转动连接在盘体121，该同步连杆31另一端连接在悬臂122末端。
根据需要，该椅座部分20和支撑部分1(如盘体121)之间或/和该滑座41和支架40之间或/和该第一滑杆21和椅座部分20之间设第一锁紧机构，第一锁紧机构锁接即可使多功能平衡椅保持在平衡椅状态或座椅状态，松释锁紧即可变化多功能平衡椅。该第一锁紧机构如采用锁孔和插销的配合，插销插入锁孔即锁紧，拔出即松释。根据需要，还可在椅座部分20和跪垫部分30之间设第二锁紧机构。
本实施例的具体结构中，该椅座部分20包括一坐垫桥架23、凸出部分22、坐垫24，该坐垫24呈凸字形结构固定在坐垫桥架23、凸出部分22之上。坐垫桥架23、凸出部分22可以为一体结构。该跪垫部分30包括一跪垫架34和两跪垫35，该跪垫架34呈凹形结构，该两跪垫35分别固接在跪垫架34之左右部，该支撑臂33固设在跪垫架34前部之下。该椅座部分和跪垫部分的轴线穿过坐垫桥架23前部和跪垫架34前部。
多功能平衡椅的变化过程如：向上拉动椅座部分20后部时在同步连杆的作用下跪垫部分30与椅座部分20的倾斜角度呈相反方向同步改变，在椅座部分20前倾30"～40"角时锁止完成改变。
实施例二
