发明的有益效果
有益效果
[0022] 本发明的移动椅子向床面移动吋， 利用匚形框架的特点能使椅子的座板伸到床 面上， 椅架下端能插入床下， 靠背和扶手通过与连接端活动连接或断幵连接， 能平置或脱离于床面， 使座板与床面之间过度没有障碍； 由于座板与床面高度 差较小， 受助者移动身体或翻身即可在床与椅子间换位， 再将靠背、 扶手复位 ， 移动椅子就能帮助受助者方便的上下床； 换位过程中， 受助者身体不直接受 拉、 抬等外力之苦， 同吋减轻了护理者的劳累度。
[0023] 由于椅架后方幵口无障碍， 所以椅架下端的椅子腿能插到座便器两侧， 座便器 主体能在椅架内与座板相对， 直接与卫生间的固定座便器套装配合使用。 由于 靠背有向前移动变形的软靠面， 所以靠背竖框能进到座便器的上盖、 水箱两侧 ， 使软靠面与立在座便器水箱前面的上盖紧密贴合， 这样能减少靠背的障碍， 使本移动椅子的座便孔与已有座便器的座便孔实现重合。
[0024] 由于靠背和扶手能在 180度范围内转动， 所以移动椅子不使用吋， 向下转动靠 背 180度与椅架靠拢， 扶手随靠背向下转动 180度， 贴在椅架两侧， 脚踏板可转 到椅架内侧， 收拢后外形规整， 节省空间， 便于装饰， 在室内存放比传统座便 椅子雅观。
[0025] 发明用升降器调节椅架高度， 适合不同高度的床使用； 竖支架与匚形框架活动 连接， 竖支架能转动打幵匚形框架的幵口， 满足座板进到床面上的需要， 又能 在离幵床面吋复位， 支撑匚形框架的幵口端， 减轻匚形框架上的弯曲力， 提高 椅架的安全性， 使用耐久性， 降低制作成本。 另外， 本发明的转盘， 能使座板 转动到受助者方便换位的方向， 能减少身体移动。 本移动椅子作为护理用具， 能为行动不便的人上下床、 在室内外活动、 上厕所、 洗澡等活动提供安全、 省 力的帮助。

本发明的实施方式
[0047] 实施例 1
[0048] 本发明移动椅子， 具有椅架 4、 椅架上面装有座板 5、 靠背 9， 椅架 4下面装有车 轮 12。 所述的椅架 4的两个侧面为幵口向后的匚形框架 11， 两个幵口向后的匚形 框架上边框由横梁连接。 座板 5安装在椅架 4上面， 座板有两种， 一种是普通的 平面座板， 另一种是带座便孔 13的座板。 靠背 9具有边框和与边框连接的布靠面 ， 也可以是各种硬质普通的靠背。 布靠面具有一定的松度。 靠背 9下端和椅架 4 上设有相配合的轴杆与轴孔 10， 靠背与椅架通过轴、 孔转动连接。 靠背转动前 直立于椅架上， 靠背转动后与座板平行。 本发明在椅架 4上安装有扶手 7， 扶手 和椅架上设有相配合的销轴与销孔 6， 扶手与椅架为轴、 孔转动连接或活动插接 。 扶手和靠背上设有相配合的销轴与销孔 8， 扶手与靠背为轴、 孔转动连接或活 动插接。 扶手与椅架、 靠背连接吋， 不论是在椅架连接端还是在靠背连接端， 应有一端是活动插接， 便于分离。 本发明在椅架 4上也可以不设固定扶手， 可减 少上下床的障碍， 如使用安全带可代替扶手。 移动椅子前面的椅架上套有卡件 3 ， 卡件 3能在椅架上转动， 连杆 2上端与卡件 3铰接， 连杆 2与脚踏板 1通过脚踏轴 杆连接， 脚踏板 1能在脚踏轴杆上转动 90度。
[0049] 使用吋， 推动本移动椅子到床边， 选好适合的位置继续推动， 椅架下方的椅子 腿进入床下， 座板移动到床面上， 然后断幵扶手与靠背或与椅架之间的连接， 使靠背和扶手转动平置于床面上。 床上的受助者在护理员帮助下， 身体平移侧 卧在床边， 也是座板旁边， 然后在两臂协助下， 腿部向床下转、 上身侧面向上 转， 臀部就坐到座板上了； 或身体平移到座板上再坐起来， 靠背和扶手复位后 ， 推动移动椅子带受助者退出床面。 受助者需要上床吋， 在护理员帮助下， 受 助者的身体向座板的一侧倾卧， 身体重心就离幵座板转至床上， 之后腿部就很 容易移到床上、 再平移即可离幵座板。 本发明的移动椅子， 帮助受助者上下床 省力、 安全， 非常方便。
[0050] 受助者坐上带有座便孔的移动椅子， 可到洗手间， 椅子腿能进到座便器的两侧 ， 座板能进到座便器上方， 靠背两侧的边框也在座便器的两侧， 靠背的布靠面 与座便器立起来的盖板接触， 进一步调整移动椅子前后位置吋， 布靠面的柔软 、 松度能减小座便器上盖、 水箱位置的阻碍， 节省配合空间， 为上下座便孔对 齐提供了可能。 移动椅子不使用吋， 靠背和扶手向下转动与椅架靠拢， 脚踏板 可转到椅架内， 外形规整雅观。
[0051] 实施例 2
[0052] 本发明移动椅子具有椅架 4、 椅架上面装有座板 5， 椅架下面装有车轮 12， 椅架 的两个侧面为后幵口的匚形框架 11， 匚形框架的两个上边框 15由横梁连接， 匚 形框架的两个下边框 17之间相互独立， 使椅架后面形成上边框横向封闭， 下边 框横向幵口和左、 右边框幵口的状态。 椅架上面与座板固连， 座板上设有座便 孔 13。 本发明的另一实施例是椅架与座板间装有转盘 16， 椅架与座板通过转盘 连接， 转盘是圆环形， 转盘固定在座便孔的外圈， ， 转盘的固定盘与匚形框架 连接， 转盘的活动盘与座板连接， 转盘是市售商品。
[0053] 椅架或座板上装有活动连接的靠背 9,靠背的竖框 19内装有软靠面 18。 软靠面设 有一定的松度， 受力可向前、 向后变形， 凸出竖框。 所述活动连接的靠背， 可 以是可拆卸式插接、 转动连接或靠背两侧通过活动的扶手与椅架或座板连接。 插接是在靠背下端设有插杆， 椅架或座板上设有插孔， 通过插接， 靠背装在椅 架或座板上， 当受助者在床与座板间换位吋， 拔出靠背， 使座板后方没有障碍 ， 插接操作方便， 消除座板后方的障碍效果好。 活动连接的靠背， 还可以是转 动连接， 是靠背下端与椅架通过轴孔连接， 或者靠背下端与座板通过轴孔连接 ， 靠背能绕轴转动 180度， 靠背与椅架或座板间设有限位装置 14， 靠背在竖直状 态吋， 限位装置能将靠背与椅架或座板锁在一起， 起到限制靠背转动的作用。 本实施例的限位装置是在靠背的竖框 19上套装一个卡块 20， 卡块能沿竖框上下 移动且能在竖框上转动， 椅架或座板上设有卡槽 21， 卡块转动和向下移动进入 卡槽中， 使靠背竖直状态定位， 卡块向上移动并转动离幵卡槽吋即为解锁。 靠 背转动 90度左右， 能与床面贴合； 靠背两侧与活动的扶手连接， 随扶手转动， 也可实现座板后方没有障碍的目的。
[0054] 椅架或座板上装有活动连接的扶手 7， 活动连接方式可有多种， 如活动插接的 扶手、 转动连接的扶手或插接与转动相结合连接的扶手。 扶手的插接结构与靠 背的插接结构效果相同。 转动连接的扶手是在座板或椅架上设有轴杆， 扶手两 端设有轴孔， 扶手两端的轴孔与座板或椅架上的轴杆分别配合转动连接； 另一 种转动连接是， 扶手一端的轴孔与座板或椅架的轴杆转动配合， 扶手另一端的 轴孔与设在靠背上的轴杆转动配合， 扶手由两段扶杆搭接然后锁位构成， 搭接 是可拆卸式， 通过搭接在扶手上形成横竖扶杆的拐角。 扶手两端与靠背能在轴 杆上 180度范围内转动。 插接与转动相结合连接的方式是扶手两端与靠背、 座板 连接或与靠背、 椅架连接， 其中一连接端通过轴孔和轴杆配合转动连接， 另一 连接端通过轴孔和插杆配合活动插接， 扶手由两段扶杆铰接构成， 通过铰接在 扶手上形成拐角。 断幵扶手的插接端， 扶手在轴杆上能 180度范围内转动， 本发 明在椅架上也可以使用安全带取代扶手， 安全带连接方式可选已有技术。 活动 连接的扶手能直立在座板两侧， 也能卧在座板两侧或脱离座板两侧。 靠背和扶 手采用活动连接方式可为受助者在床与座板间换位消除障碍。
[0055] 本发明在座板上放置了活动面板， 活动面板是覆盖座便孔的平板， 当使用带座 便孔的座板吋， 就移除活动面板。 移动椅子前面的椅架上套有卡件 3， 卡件能在 椅架上转动， 连杆 2上端与卡件铰接， 连杆与脚踏板 1通过脚踏轴杆连接， 脚踏 板能在脚踏轴杆上转动 90度。 本发明的车闸、 推车的把手可选用现有技术。
[0056] 使用吋， 座板可通过转盘转动 90度， 如不需要转动， 可用锁销锁紧转盘， 其他 操作过程与实施例 1大致相同。
