Description

一种仿生正姿桌椅 技术领域
本发明涉及一种仿生正姿桌椅, 尤其是一种中小学生用的仿生正姿桌椅。
背景技术
针对当今中小学生近视、 驼背等现象呈不断上升的趋势, 为其设计一种比较合理、 科学 的桌椅, 已成为社会各界有识之士及广大师生和家长的强烈愿望和要求, 也已成为不少有心 人的一块心病。
造成这种不良现象的原因是多方面的, 后果是严重的。 从学校卫生学的角度说, 将上体 重心落在坐骨结节之上或其前方的姿势称为"前位坐姿", 此时由背部肌肉的紧张及大腿来维 持平衡; 把上体重心落在坐骨结节之后称为"后位坐姿", 背部必须有倚靠。 很明显, 趴在桌 上的"前位坐姿"容易出现疲劳, "后位坐姿"不易疲劳。 但目前, 学生却比较普遍采取"前位坐 姿"的姿势趴在桌上学习。从生理学的角度说, 当视线与所视物体呈垂直角度时, 在视网膜上 的成像最为清晰, 称为生理视角。 学生在学习时为了追求最为清晰的视角就只能低头。 从生 物学的角度说, 骨是由硬脆的无机物和柔韧的有机物组成的, 骨的物理特性主要表现在硬度 和弹性这两个方面, 并且骨中不同成分的含量和骨的物理特性, 又是随着人的年龄的增长而 变化的。 比如儿童少年期骨质特性是硬度小, 柔韧, 弹性大, 虽不容易发生骨折, 但容易变 形, 如果长期不注意学习、 写字的姿势, 就会引起驼背、 背脊侧弯及近视等症状。 北京第四 医院主治医师刘志明经过多年的探索, 最后得出一个结论: 青少年长期学习姿势不正确, 不 但容易疲劳, 患近视、 驼背, 还有一个更加严重的后果没有被人们重视, 那就是这些学生成 年后将是颈椎病的高发人群。
认识这种不良现象的深度, 还是有限的。 由于目前学生学习姿势不正确, 尤其是比较普 遍地采取"前位坐姿"的姿势趴在桌上学习, 有的在想方设法改进这种姿势, 还没有认识到 "后 位坐姿 "的作用, 有的又矫枉过正, 片面地强调"后位坐姿"的作用, 还没有感受到 "前位坐姿" 是不可缺少的, 并且也是可以将其改进成正确姿势的。 实际上, 没有"前位坐姿", 就不利于 中国传统的毛笔使用, "后位坐姿"相对作为 "前位坐姿"的一种姿势, 目前也还存在趴在桌 上学习的问题。 并且正确的前、 后位坐姿作为学习的两种基本姿势, 也应该是可以随意互换 的, 在互换的过程中还存在一些交替姿势, 也是应该存在的, 因人总不能以一种姿势坐着。 并且这些姿势都能达到传统的 "三一"学习姿势要求, 即: 胸距桌沿一拳, 眼距书本一尺, 及有利于达到手指距笔尖一寸。
解决这些问题的措施, 还不是很得力的。 人们也发明了多种桌椅。 如目前一种较为时尚 的桌椅之一的新知健康学习桌 (申请号 02354452), 桌可以固定下来, 后桌面是倾斜的, 并 带有托肘板, 桌椅能调节高度, 且桌脚踏板也可上下移动调节高度, 意欲达到正确学习姿势 的"后位坐姿"的目的, 不足之处是椅难以调节到与桌的适当距离, 并且调节好了要换个位置 或出来难, 若另用椅子 (申请号 03330221 ), 椅腿上有轮, 能比较方便地调节桌与椅之间的 距离, 不足之处是, 去开关椅轮又不方便, 并且就是调节好了桌椅之间的适当距离, 也会趴 在桌上学习, 因胸前的凹形护胸起不了多少作用。 若在教室使用, 桌与椅或桌椅与桌椅之间 的高度不一致会影响美观。 如一种自然预防、 治疗近视和驼背的新型课桌 (申请号 03238636.2), 其上安装有类似本发明的桌靠架, 由下巴垫连结在其上的横梁, 上、 下调节支 柱和与桌面后沿活连等组成, 横梁与桌沿之间为单柱的上、 下调节支柱前后相叠, 并通过其 上的调位孔用螺栓固定, 下调节支柱下端与桌沿之间为活连并固定连接, 上下调节支柱宽约 为胸部宽的三分之一, 并向后稍倾斜, 上调节支柱在人伸直腰稍向后靠时下端至胸部下端和 桌沿, 在弯腰稍向前靠时下端至桌沿或胸部下端稍下, 前桌面上有类似看书架的阅读板, 人 是趴不下了, 意欲达到正确 "前位坐姿"的目的, 不足之处是人坐在椅上前靠后靠, 桌容易摇 晃, 加之进出和换坐姿困难, 桌椅高度也不能调, 目的自然难以达到。 如一种矫正坐姿的读 写桌连椅 (申请号 03275800), 能按正姿要求调节桌椅之间的距离并连为一体, 意欲能达到 正确学习姿势 "前位坐姿"的目的, 不足之处是胸前无依靠, 还是趴在桌上学习, 并且桌椅不 能活动地随意调节, 还不能调节高度。
这些桌椅, 归纳起来问题主要有: 一是桌椅高度调节有的还没解决这个问题, 有的解决 了的又难已普及, 还摆在教室里同样高在那里, 因为调节得高的高, 矮的矮, 很不美观, 加 之调节方式很复杂。 二是桌椅之间距离调节有的还没有解决这个问题, 有的已经基本解决了 的还存在不能随意使桌椅活动连为一体, 能活动连为一体的又难保持住等问题。 三是桌面、 桌椅腿、 托肘板、 桌靠架、 看书架、 椅背等结构发挥的作用, 还没有达到正确的"前位坐姿" 和"后位坐姿"及之间的过渡姿势并易于互换及眼睛与摆书板始终处于最佳距离和视角的目 的。 此外, 桌椅的整齐摆放、 上下课桌椅移动的声响, 以及便于打扫卫生等问题也注意不够, 有的年级桌箱放书的空间还太小, 为小孩考虑得还不多, 桌椅移动还不方便。
发明内容
本发明要解决的技术问题, 是提供一种一坐始终处于正确的 "前位坐姿"和"后位坐姿" 及之间的学习姿势, 并可随意方便地更替姿势和出进, 不易疲劳的仿生正姿桌椅。
为实现上述目的, 本发明采用的技术方案是: 所述仿生正姿桌椅, 包括一种单体或连体 的桌椅或桌凳, 桌腿下部连接有脚踏板; 椅背支柱之间连接有椅背, 其结构特点是: 在所述 在桌椅的上部和下部, 以及或桌椅之间或桌腿之间与椅腿之间有一个正确的 "前位坐姿"和 "后位坐姿"及之间的学习姿势并可以随意更替的正姿装置及安装该正姿装置的机构; 在桌 面与桌箱之间设有可调节桌面高度和倾斜度的桌面升降机构。
