半自动防夹手装置 技术领域
本发明涉及一种与门有关的特殊结构， 具体地说， 涉及一种防止手或手指 被门夹住的装置。 背景技术
曰常生活中， 人们可能会遇到不小心手或手指被门夹住的情况， 特别是一 些孩童， 在玩耍时或在没有人看管的时候手被房门夹住 /挤压而受伤的情况时有 发生。
在一份名为 《Injury》 (Injury, Int. J. Care Injured, Volume 31, Issue 8, October 2000, Pages 571-573) 的国际性刊物中， 刊登了一份由 N, V.
Dora i s wamy等人撰写的标题为 "Isolated f inger injuries in Chi ldren - incidence and aet iology" 的文章。 文中指出： 某意外及紧急部门对其接收的 所有孩童所作的一份特别问卷调查结果是， 在一段为期 6个月的时间内， 426 个孩童当中有 283个孩童的手指受伤， 大部分是发生在家中（59%) , 而且年龄多 小于 5岁（38%) ......最通常的原因是被"夹住 /挤压"（48W 而弄伤，多数孩童（59%) 被客厅 /起居室的门弄伤（32%) , 而且通常是在门轴处发生的（49%) ......很少情况 下是孩童在关门时自我伤害。 该报告还指出： 孩童关门时弄伤手是很普遍的（占 60%) , 当然也有的是因意外情况由成年人造成的 '(占 25%) ......不论是孩童， 还 是成年人， 都应该反复受教导， 采取安全措施以防手指受到伤害。
一种门塞可阻止门关闭。 但当门没有被塞住时， 意外就会很容易发生。 有人设计了一种防夹手装置， 该装置通过将一防撞器夹在门锁或门轴一侧 上可防止门关闭。 若要关门时， 必须先用手将它取下。 也就是说， 必须每次用 手将它夹在所述位置上才能阻止门关闭。 因此， 一旦缺乏重视或是疏忽大意而 忘了将它放置在位， 就有可能发生手指被弄伤的意外。

确 认 本 Dorner Jorg Dr. - Ing等人的德国专利第 DE3626924号揭示了一种防夹手装 置。 该装置包括长的条状或棒状遮盖物， 该遮盖物通过薄的挠性连接件沿门的 长度轴向固定在门轴的缝隙处， 从而遮掩门缝。 虽然避免了门轴位的缝隙夹住 手指， 但在门锁一侧的缝隙处仍会发生夹指的情况， 而且由于该装置由门顶部 一直延伸至门底部， 因此安装起来不太方便。
Steven Swaddle等人的英国专利第 GB2218449号也揭示了一种防夹手装置。 该装置&括一桥接式带状件， 由两端部和两中间部分组成， 两中间部分分別通 过一铰接部分串接在一起， 两端部则分别固定在门面和门框上， 以此遮掩门轴 缝。 由于该装置各组成部分以塑胶制成且一体成形， 以致于其使用寿命较短、 容易变形或折断。 而且， 也同样存在门锁一侧的缝隙处仍会发生夹指的缺点。
Stephen Robert Webb 的英国专利第 GB2306538 号还揭示了一种防夹手装 置。 该装置大致上类似于上述 Steven的发明， 主要目的是为了遮掩门轴缝。 因 此， 也存在同样的缺点。 发明概述
为解决上述的问题， 本发明提供一种半自动防夹手装置， 避免手或手指在 门锁一侧或是在门轴一侧被夹伤这一类主要的意外伤害的发生。
本发明的目的是这样实现的：
本发明半自动防夹手装置包括： 一緩冲器， 在关门状态下， 其处于门外侧 表面与门柱之间， 而在开门状态下， 其处于门轴缝隙中； 一保持所述緩冲器的 固定装置以及一连接件， 连接件的两端分别与所述緩冲器和固定装置作可伸缩 连接。
在一实施例中， 所述緩冲器包括一内置的可使所述连接件长度伸缩的弹性 卷绕装置。
在另一实施例中， 所述固定装置包括一内置的可使所述连接件长度伸缩的 弹性卷绕装置。
所述弹性卷绕装置包括一中空套筒， 该套筒的壁上沿纵向设有一第一细长 孔， 所述连接件从该孔中通过， 一空心卷筒， 其置于所迷套筒内并使所述连接 件的一端固定在其上， 一螺旋式弹簧， 其置于所述卷筒内， 一第一盖件和一第 二盖件， 它们分别安置在所述套筒的两开口端上， 并且所述弹簧的一端与所述 第一盖件连接， 另一端固定在所述卷筒上。
所述第一和第二盖件之一的内端壁上设有一凹槽， 该凹槽接纳所述卷筒的 一端部并允许该端部在其中转动。
或者， 所述第一和第二盖件的内端壁上各设一凹槽， 每一凹槽接纳卷筒的 一端部并允许该端部在其中转动。
所述第一盖件的内端壁上设有一自其上凸起的圆柱体， 所述弹簧固定在所 述圆柱体上。
所述第一和第二盖件内端壁的凹槽与所述卷筒的相应端部之间分别放置一 辅助所述卷筒转动的轴承。
所述弹性卷绕装置还包括一轴， 所述第一盖件的圆柱体的自由端上设有一 容纳并固定所述轴一端的轴孔， 所述第二盖件内端壁的凹槽中设有一容纳并固 定所述轴另一端的轴孔。
所述连接件由柔软具韧性的材料制成且足够薄， 以致可置于关闭状态下的 门缝中。
在又一实施例中， 所述连接件以弹性材料制成且足够薄， 以致可置于关闭 状态下的门缝中。
一牵拉件固定在所述緩冲器上。 所述牵拉件是一固定在所述緩冲器两端的 绳线。
所述套筒以金属材料制成。 套筒的外表面设置一以韧性材料制成的保护层， 该护层上具有一与所述套筒壁上的第一细长孔对齐的允许所述连接件通过的第 二 田 "^孑 Li。
所述固定装置包括一阖筒， 该圆筒具有一允许所述连接件通过的孔隙， 一 与所述连接件的另一端作固定连接的杆。 所述孔隙自圆筒的一端沿纵向向内延 伸形成半封闭式孔隙。 所述固定装置还包括一阻止所述连接件自所述半封闭式孔隙离开所述圆筒 的可拆式挡件。 固定装置的圆筒的外表面设有一防滑层。
在再一实施例中， 固定装置由一片状固定件构成。
对于需要使用者每次开门都要留意重新安装的装置来说， 本发明克服了这 个问题。 由于本发明的防夹手装置的独特结构以及其半自动的特性， 因此不需 要重新安装。 当门打开时， 装在门轴上的缓沖器借助内置弹簧的力而即时恢复 原位， 即时阻止门关闭， 从而预防手指被夹伤。
为更清楚理解本发明的目的、 特点和优点， 下面将结合附图对本发明的较 佳实施例进行详细说明。 附图说明

图 2是图 1所示装置的部件分解图；
图 3A至 3C是本发明半自动防夹手装置的使用状态示意图；
图 4是本发明半自动防夹手装置的另一实施例的示意图。 较佳实施例的描述
请参见图 1 , 根据本发明的半自动防夹手装置 10包括一缓冲器 20， 一固定 装置 30以及一使所述缓冲器和固定装置连接在一起的连接件 40。
在第一实施例中， 如图 2所示， 缓冲器 20包括一弹性卷绕装置 200, 该装 置包括一中空套筒 210、 一置于套筒 210内并可在其中活动的空 卷筒 220、 一 置于卷筒 220内的螺旋式弹簧 230以及第一盖件 240和第二盖件 250。
在套筒 210壁上沿纵向设置第一细长孔 1U , 该孔允许连接件 40通过。 第 一和第二盖件 240， 250分别安置在套筒 210两端开口上。 第一盖件 240与螺旋 式弹簧 230 的一端连接。 在本实施例中， 第一盖件自其内端壁表面， 最好是中 心位置处凸起一圆柱体 244, 弹簧 230 的一端固定在该圆柱体上， 而另一端则 固定在卷简 220上。 第一盖件 240和第二盖件 250的内端壁上可分别设置一凹 槽 242, 252 , 用以接纳卷筒 220 两端并允许它们在其中活动。 为协助卷筒两端 在凹槽 242 和 252 中转动顺畅， 可在各凹槽与卷筒的接触面之间放置一轴承 260 (图 2中只显示了其中一个）。
为防止螺旋式弹簧 230工作时扭曲或变形， 可配置一轴 270并在第一盖件 240的凸圆柱体的自由端上设置一轴孔 246 , 轴 270的一端固定在该轴孔中， 另 一端插入弹簧 230中以保持该弹簧。 本实施例中， 第一盖件 240和第二盖件 250 中各设置一轴孔 246和 254, 轴 270穿过弹簧 230且其两端分别固定在相应的 轴孔 246和 254中。
緩冲器 20的套筒 210最好设计成圆筒形（但不限於此）， 可减小门边和门轴 对其施加的压力以及它们之间所产生的摩擦力。 套筒 210 最好以足够硬度的金 属材料制成， 诸如不锈钢。 为防止缓冲器 20的套筒 210与门直接接触， 因碰撞 或摩擦而可能对门造成损坏， 可在套筒的外表面设置一保护层或套上一保护套 280。 该保护层或保护套 280可由韧性材料， 例如软硬度适中的橡胶材料制成并 具有一定的防滑功能。 该保护层或保护套上设有与套筒的第一细长孔 212 相应 的允许连接件 40通过的第二细长孔 282。
连接件 40以柔软具韧性的材料制成且足够薄， 以致可置于关闭状态下的门 缝中。 穿过套筒 210上设置的细长孔 212的连接件 40, 其一端固定并卷绕在卷 筒 220上， 另一端固定在固定装置 30的一杆 320上。
固定装置 30还包括一圆筒 310。 圆筒 310的壁上沿纵向设置一允许连接件 40通过的孔隙 312。 该孔隙可自圆筒 310 的一端向内纵向延伸形成为半封闭式 的孔隙。 为防止连接件 40 自孔隙开口离开圆筒 310, 可在圆筒开口端设置一挡 件 330。 还可在圆筒 310的另一开口端设置一盖件 340, 以使杆 320遮掩在圆筒 310 内。 圆筒 310和杆 320可以任何具一定硬度的材料制成。 为避免因重心引 力令装置下滑， 还可在圆筒 310 外表面包裹一由防滑材料， 例如网络状软塑胶 制成的防护层 350以增大摩擦力， 有助于使固定装置稳固地保持在位。
另外， 固定装置 30也可包括一其上置有可使所述连接长度伸缩的弹性卷绕 的卷绕架（图中显示）。 所述卷绕架可以螺钉磁力或粘贴等方式固定在门内侧表 面或门柱上。 连接件的一端卷绕在卷绕架上， 而另一端与緩冲器作固定连接。 图 3A至 3C显示了本发明装置一实施例在静止和使用状态下的示意图。 在 图 3A 中， 本发明装置处于原位静止状态， 即， 緩冲器 20处于门轴缝隙中， 固 定装置 30处于门 30内侧表面与门柱 70之间， 连接件 40藉由緩冲器 20的弹性 卷绕装置 200收藏在该缓冲器的套筒内。 收缩的连接件使得緩冲器 20与固定装 置 30紧靠一起地卡在门轴缝中， 由于緩冲器与固定装置的外表面均包覆有塑胶 保护层或防滑层， 使得它们不易于在门轴缝中滑动。
图 3B显示了在缓冲器 20上施加拉力， 使连接件 40 自緩冲器 20的弹性卷 绕装置中拉伸出来， 从而使緩冲器沿方向 A自门轴缝隙中拉出。
在图 3C 中， 因緩冲器被拉出使得门可关上， 緩冲器 20藉由弹力而保持在 门外侧表面与门柱之间。 为了便于牵拉緩冲器， 可在该緩冲器的适当位置上设 置一牵拉件 50, 例如拉绳或拉环。 在本实施例中采用一拉绳， 其固定在缓冲器 两端的盖件上。 当然， 也可以使用其他形式的牵拉件。
当门再度被打开时， 连接件 40藉由弹簧的作用力回卷到卷筒 220上， 从而 使緩冲器自动回到原位， 即门轴缝隙中， 阻止门关闭。
当然， 緩冲器和固定装置可以采用其它适合的形状。
在第二实施例中（图中未示）， 缓冲器和固定装置的结构及构件可以掉换， 即， 弹性卷绕装置 200可设置在固定装置 30 中， 而緩冲器 20的结构则相当于 前述实施例中的固定装置。
在第三实施例中， 如图 4所示， 除固定装置由一片状固定件 300构成外， 其他部件与第一实施例相同。 固定件 300 可以螺钉或粘贴等方式固定在门内侧 表面或门柱上， 连接件 40的另一端与该固定件 300作固定连接。 当然， 固定装 置还可以采用其他方式固定在门内侧与门柱之间或门内侧表面或门柱上。
在第四实施例中（图中未示）， 缓冲器和固定装置分别与连接件作固定连接。 连接件以弹性材料制成且足够薄。 而緩冲器可以是能夹在门轴缝中阻止门关闭 的任何形状的物体， 而固定装置可以是通过各种普通方式固定在门内侧表面或 门框上的任何形状的物件。 在使用中， 通过弹性连接件的伸缩性来达到本发明 的目的。
以上所述的仅是本发明的优选实施例。 应当指出， 对于本领域的普通技术 人员来说， 在不脱离本发明原理的前提下， 还可以作出若干变型和改进， 这些 也应视为属于本发明的保护范围。
