背景技术
现代人们的卧室陈设， 床前不能缺少电视机， 喜欢在床上看电视， 有些人还欢喜上床 看书阅报。 由于床靠背是固定的， 不能调节倾斜度， 人们只得用靠垫来弥补。 但得不到如 意倾斜度， 无法达到舒适靠背。 虽然也有各种传统的坐椅和躺椅可调节靠背的倾斜度， 但 都无法适用依壁放置的床靠背。 如有一种躺椅， 其靠背与坐躺面间有一可旋转的轴， 靠背 髙度可以调节。 当靠背放低时， 靠背前部位置后移； 靠背调高时， 靠背前部位置前移。 这 就带来一些问题： 位置前移会使使用者观看前面景物的间距缩短； 位置后移时， 若躺椅靠 壁放置则无法实现， 若将躺椅拉开离壁放置， 一使室内不整齐， 二若对床来说， 拉开会受 到房间空间的限制而不允许。另外，拉开肯定缩短观看电视的距离。也有调节倾斜度的床， 大多是调节床面架的前面部分， 这样的床同样存在上述问题。 而且， 床上部摇起时， 连同 席梦思床垫一起摇起， 这将是不可想象的情况。 中国专利 ZL94209103.5 , ZL03273833.1 公开了一种床头靠背处设置类似靠背板的装置， 平时靠背板与床头架平行与床面垂直放 置， 需要调节床头靠背倾斜度时， 靠背板能从底部掀起与床面形成倾斜度。 虽然能解决一 部分问题， 但由于靠背板均以其上端为中心旋转式掀起， 靠背板上端高度始终未能降下， 使用时上部太高， 更严重的是， 其下部未能与床面连接， 无法实现舒适靠背。

⑧、 ⑨， 平行机构也可以是： 图 2或图 3单个结合图 4的单恻， 蜗杆操纵器操纵单个 卧式单体支承臂 4a、 单个卧式铰链折叠支承臂 4b。 卧式单体支承臂 4a—端转轴 7顶端的 导套 6b配于靠背 10下端的导柱 32， 或卧式铰链 35折叠支承臂 4b—端转轴 61顶端连接 靠背铰链 34, 二者支承臂另一端都可铰接在靠背柱横樑 5中部铰链 3' (如图 6左侧)， 所述 的支承臂铰链 3'轴腔局部外径上的蜗轮 42与支承臂 4a、4b平行设置的蜗杆 43操纵器配合。 此二方案无单独图， 但支承臂结构的设计分别是图 2、 图 3的一半， 而二者均采用图 4中 单端蜗杆操纵器。
⑩、 平行机构也可以是如图 6右侧图和图 5所示： 蜗杆操纵器操纵立式支承臂 4c。 立 式支承臂 4c上端铰接靠背 10背面中部铰链 46，下端铰接靠背柱横樑 5中部铰链 3c，所述 的铰链 3c轴腔局部外径上的蜗轮 42与蜗杆 43操纵器相配合。 所述的蜗杆 43设置在靠背 柱横樑 5上的轴承座上的蜗杆轴上。 蜗杆轴的转动是由手动操作通过角尺齿轮改变旋转方 向， 在角尺齿轮输出的轴端配置圆盘 15或摇手 12。 也可以配电动机直接驱动蜗杆 43。 所 述的设于靠背 10背面的立式支承臂 4c可以是一支以上。
⑪一 ©， 还可以是： 图 2单个或图 6左恻、 图 6右侧结合图 8， 液、 气压操纵器操纵 单个卧式单体支承臂 4a， 单个单向卧式铰链折叠支承臂 4b， 立式支承臂 4c的结构。 卧式 单体支承臂 4a—端转轴 7顶端的导套 6b配于靠背 10下端的导柱 32(如图 2—半)；或卧式 铰链 35折叠支承臂 4b—端转轴 61顶端连接靠背下端中部铰链 34(如图 6左侧、 图 7); 或 立式支承臂 4c上端铰接靠背 10背面中部铰链 46(图 6右侧图)； 三者支承臂另一端分别铰 接在靠背柱横樑 5中部铰链 3'、 3'、 3c, 单向液压或气压缸 65操纵器缸柱 64端头铰接连 杆 63， 所述的连杆 63另一端铰接于支承臂 4a、 4b、 4c与铰链 3'、 3'、 3c铰接部的上段的 铰链 41(如图 3)或铰接于铰链 3'、 3'、 3c伸出的尾部 62(如图 8)的结构。此三个技术方案均 采用单向液压或气压缸操纵器分别操纵卧式、 立式三种支承臂。
很明显， 以上几个 "平行机构"的技术方案都可以相互替代。 同样， 图 1中所示的靠 背 10上端配合靠背 10下端平行的同步升降机构也有其它技术方案可以相互替代。 它可以 如图 9所示： 靠背 10两侧上端铰链 28的铰链轴 69—端连接滑轮架 66， 所述的滑轮架 66 两端滑轮 68运行于两侧靠背柱 2内侧导轨 67。 也可以如图 10所示靠背 10两侧上端方型 壳体铰链 74动配于铰链外壳 75内腔， 其铰链轴 69端的滑轮 68运行于两侧靠背柱 2内侧 导轨 67。所述的方型壳体铰链 74与靠背 10之间有靠背压弹簧 71和斜度推块 73配合斜度 靠背柱锁 70， 靠背柱锁 70设有靠背柱锁复位压弹簧 72。 该同步升降机构除同步升降功能 外， 还具有锁住靠背 10上端功能。 当靠背 10受压时， 斜度推块 73将斜度靠背柱锁 70推 向靠背柱 2， 从而把靠背 10上端固定在调节好的位置上。 当靠背 10没有压力时， 靠背压 弹簧 71复位，同时斜度推块 73复位，靠背柱锁 70在靠背柱锁复位压弹簧 72作用下复位。 这一方案特别适用于使用 "卧式支承臂"平行机构的技术方案中。 "升降机构"也可以如 图 11所示： 靠背 10上端两侧铰链 28的铰链轴 69连接靠背柱 2外径动配导套 29， 此结构 与图 2中 "升降机构"差别仅在于本方案的靠背柱是六角形。该靠背柱的形状可以是圆型、 六角型或方型等多种形状。 "同步升降机构"也可以如图 12、 13所示： 靠背 10两侧上端 铰接滑轮架 77铰链 76， 滑轮架 77平行滑轮 80运行于与靠背 10背面相对的导轨 79。 所 述的滑轮架 77设有一锁住道轨 79的凸轮 78锁扳手 81。当靠背 10的倾斜度调节至最舒适 位置时， 将凸轮锁扳手 81扳下， 滑轮架就锁住在这一位置上， 它主要用于 "卧式支承臂" 平行机构的靠背 10上。 "同步升降机构"也可以如图 14、 15所示： 靠背 10两侧上端铰接 靠背导柱 82顶端铰链 84， 其导柱 82动插配于靠背柱 2内径， 所述的导柱 82下端和靠背 柱 2上端口有轴行滑轮 83的结构。 选用这一技术方案时， 靠背 10上端下降后， 靠背上端 不会外露靠背柱 2， 比较美观。
以上提供了数种 "平行机构"和 "同步升降机构"的技术方案。 在 "平行机构" 和 "同步升降机构"之间， 它们都可以在具体实施中互相互换和替代应用。 并且以上二个机 构之间又可任意组合形成一个 "升降机构"配合 "平行机构"完成靠背 10下端在坐躺面 平面上前后平行运行的动作。 而 "平行机构"中是由操纵器操纵支承臂的。 蜗杆操纵器与 液压或气缸操纵器之间可以互换， 这二个操纵器又都可以替代迂迴拉索操纵器。而操纵器 的动力来自动力源。 本发明的动力源为： 丝杆 8、 拉索 31、 蜗杆 43是圆盘 15或摇手 12 等手动， 或者是电动机驱动； 所述的双向或单向液压或气压缸 37、 65 为手动液压或气压 泵或是电动液、 气压泵的结构。 它们的电动操作可以是倒顺开关、 倒顺按钮或遥控。
为使用者在使用时更感舒适， 本发明在所述的靠背 10上端设有枕头靠调节装置， 它 可以是如图 16和图 2左侧所示： 枕头靠 18下端铰接在靠背 10上端前侧的铰链 23， 枕头 靠 18背面下端有随铰链 23旋转的 R型倒撑齿块 20， 所述的 R型倒撑齿块 20配有铰接的 放置弹簧的倒撑顶块 19。 当枕头靠向前倾斜时， 倒撑顶块 19在弹簧作用下自动顶住 R型 倒撑齿块 20。按下倒撑顶块 19的尾部， 倒撑顶块 19脱离 R型倒撑齿块 20, 枕头靠 18在 自重作用下复位， 也可设置弹簧复位。 图 2左侧上方为方便操作， 设置了铰接铰链 22的 横杆 21。 按下按钮 17， 横杆 21就将倒撑顶块打开， 枕头靠 18即可调节。 也可以是如图 17和图 2右侧所示： 枕头靠 18下端与靠背 10上端抽屉式道轨 24配合， 两侧道轨 24之间 有平行倒撑齿块 25， 所述的平行倒撑齿块 25配有铰接的放置弹簧的倒撑顶块 26(图 17)。 当枕头靠 18向前推进， 弹簧倒撑顶块 26在弹簧作用下自动顶住平行倒撑齿块 25，抬起倒 撑顶块 26的尾部， 倒撑顶块 26脱离平行倒撑齿块 25， 枕头靠 18可以后移， 也可设置弹 黉复位。 图 2右侧上方枕头靠调节装置中， 为方便操作， 放置了以铰链 22铰接的横杆 27， 按下按钮 17横杆顶端就会脱开倒撑顶块 26，枕头靠即可调节。也可以是如图 18和图 6左 侧所示： 枕头靠 18下端铰接在靠背 10上端前侧的铰链 23， 枕头靠 18背面下端铰接连杆 49， 所述的连杆 49另一端铰接单向液压或气压缸 85缸柱 86端头结构。 图 6左侧靠背 10 上端设有液、 气压手泵 48。 图 6右侧是传统技术为直条倒撑齿块 58和倒撑顶壳 57结构。 图 16—图 18的虚线图是枕头靠 18运行状况示意图。 所述的枕头靠 18调节可以是上述手 动也可以设置电动机驱动。
为了适应天气冷暖变化， 调整床垫厚薄的需要，本发明在靠背柱横樑 5二端设有靠背 10下端与坐躺面 13之间间距调节装置。 示例 1如图 2中所示， 其结构包括： 靠背柱横樑 5两端开口抱套 33套配靠背柱 2外径， 所述的抱套 33开口两侧两耳有紧固件 45。 松开紧 固件 45调整靠背横樑 5在靠背柱 2上的位置， 然后旋紧紧固件定位即起到了调整靠背 10 下端与坐躺面 13的间距。
示例 2如图 6中所示， 其结构包括： 靠背柱横樑 5两端套筒 60动配于靠背柱 2外径， 所述的两端套筒 60有配合轴 53连同步齿轮 52的齿轮腔， 同步齿轮 52与设于靠背柱 2两 侧的直行齿条 51吻合， 所述的两侧套筒 60还装有靠背 10下端与坐躺面 13间距的定位凸 轮扳手 59。 它的操作是扳起凸轮扳手 59， 转动轴 53连同步齿轮 52， 同步齿轮 52就会在 直行齿条 51中上、下运行使靠背柱横樑同步升降至所需间距，扳下凸轮扳手 59锁住即可。
以上所述的 "枕头靠调节装置"和 "靠背 10下端与坐躺面 13之间间距调节装置"的 数个技术方案可各自互相替代， 又可组合应用。
另外， 实施例 1是一个可以如意调节靠背倾斜度的床， 当坐躺面面积变化时也可以是 沙发、躺椅或坐椅。还可以是坐躺面架下无腿的床 (如图 5)。无腿的床是大和民族、韩民族 等民族具有民族习俗的床。 图 5所示的平行机构是蜗杆操纵器操纵立式支承臂情况， 其升 降机构为导柱 9结合导轨 1结构。 虚线所示是靠背及支承臂运行状况， 当然该床同样可安 设其它平行机构及升降机构及其它装 S。 实施例 2:
本实施例 2的基本结构与实施例 1相同。 它同样具有 "平行机构"和 "升降机构"； 同样可以安装有枕头靠调节装置和靠背下端与坐躺面 13之间间距调节装置。 所不同的是 两侧靠背柱 2之间增设双道轨的靠背柱 56(如图 6)。双道轨靠背柱 56下端连接靠背柱横樑 5。双道轨靠背柱 56与两侧靠背柱 2之间设并列的双靠背 10'。双靠背各自设一"平行机构"， 也可以是同一平行机构。 如图 6右侧的 "平行机构"采用蜗杆操纵器操纵立式单体支承臂 结构。 其左侧的平行机构则釆用蜗杆操纵器操纵单个卧式铰链 35折叠支承臂的结构 (具体 构造已有表述)。上方的枕头靠装置是采用该装置的示例 3结构，安装了手动液压或气压泵 按钮 48。 其中间还安设了一个靠背运行平稳装置， 它包括： 靠背导套 55、 一头以铰链 50 铰接于靠背 10'背面，一头插入靠背导套 55内的靠背导板 54构成。当然两侧也可设同一副 "平行机构"。 这一实施例主要是提高产品的灵活性。 其左、 右二侧的使用者按照自己的 需要将各自的靠背调节至自己适合的倾斜度后使用， 甚至一个已想休息， 另一个则还想看 书、 阅报或看电视。 当然还可以设二个以上双道轨靠背的结构， 此时它的靠背应是三个以 上。两靠背 10'以上的靠背 10'，它们可以是大小一样的并列靠背 10'， 也可以是大小不同的 靠背组合。
