Description
说明书 升降式防盗百叶窗 技术领域 本发明涉及一种升降式防盗百叶窗, 属于建筑门窗领域。
背景技术 目前城市住宅的窗户主要是推拉窗,推拉窗开启时不占据空间且可控制进风 量, 然而, 推拉窗的缺陷是推开时门户大开, 难于防止外人侵入房间, 为了保证 人身安全, 目前人们采取的措施是在窗户外墙或内墙安装防盗栅栏、防盗网和报 警器, 形式多样的固定防盗栅栏和防盗网的缺陷是, 挡住了人们眺望的视线, 在 发生火灾时, 更使人们无法打开窗户逃生, 另外牢笼式的栅栏极大地影响了城市 形象; 为了克服固定防盗栅栏的缺陷, 人们设计了形式各异的活动防盗栅栏和防 盗网, 但是这些都没有对城市形象的改观起到多大作用; 报警器似乎也解决了固 定防盗栅栏和防盗网的这些缺陷, 但是, 实践证明, 它的误报率较高, 常常让人 虚惊一场, 同时也无法满足人们看得见摸得着的那种心理安全感, 而且其老化程 度也比较高, 人们需要每隔几年就进行一次更新换代, 代价太大。
中国专利 ZL20062017017L X 公开了一种 "多功能可升降式安全防盗百叶 窗", 它由具有空腔的窗框及百叶窗窗叶构成, 窗框的空腔内装有与百叶窗窗叶 连接的升降装置和翻转装置, 窗叶两端通过端部连接头装在窗框两侧的滑槽内, 窗叶之间通过开合爪连接;该升降装置由装在窗框四角内的滑轮、钢丝绳、链条、 转向齿轮、 升降杆及连接扣构成, 钢丝绳装在四个滑轮上, 钢丝绳的一端通过连 接扣与链条的一端连接, 钢丝绳的另一端与链条的另一端连接, 链条装在滑轮上
的齿轮上, 并通过转向齿轮变更方向, 升降杆的两端固定在两侧的钢丝绳上, 并 与最下面的一片窗叶连接; 翻转机构由转轴、 转轮、 支承、 拉绳及叶片翻转器构 成, 转轴通过支承固定在窗框的上侧内, 转轴上装有转轮, 两个转轮上的拉绳与 每片窗叶的两个端部连接头连接,另一转轮上的拉绳与装在百叶窗一侧的叶片翻 转器和锁扣连接; 升降杆上装有与窗框下侧配合使用的窗锁; 该发明专利技术存 在的不足是, 穿过叶片中间的钢管除两端固定外, 相互之间没有其它加固件, 横 跨度大时极易遭到破坏; 钢管穿过叶片中间, 使叶片厚度增加, 导致采光不足; 钢管两端可以转动, 导致叶片上升收拢后占据窗户上部空间较大, 影响采光量和 外观形象。

4、 根据权利要求 1所述的升降式防盗百叶窗, 其特征在于活动栅栏由栅栏杆(76)、 栅 栏杆两端接头 (75)、 栅栏铰链杆 (78) (710) 和销钉 (79) 组成, 栅栏杆 (76) 与两端接 头(75)为固定连接, 栅栏杆(76) 的两端接头(75)为与升降螺旋杆 (21) (25)啮合的螺母 块且侧面为一平面齿条(713), 铰链杆(78) (710) 的一端套在栅栏杆(76)上, 另一端通 过销钉 (79) 连接, 所有栅栏杆 (76) 随升降螺旋杆 (21) (25) 转动而同步上升或同步下 降, 升降螺旋杆 (21) (25) 上部留出一段直径小于其螺纹外径的轴颈, 以便容纳除锁定杆 两端接头(712) 以外所有脱出螺旋运动到达顶部轴颈的栅栏杆(76)两端接头(75), 最上 方的栅栏杆 (31) 被支承 (34) 固定在窗框上部 (11), 其两端接头套在升降螺旋杆 (21)
(25) 上且搁在其轴颈圆环台阶上, 最下方的栅栏杆作为锁定杆 (81), 在锁定杆 (81) 下 落到窗框下部 (13) 时, 通过旋转窗框下部 (13) 内的锁 (83) 上的活动插栓 (84), *** 与锁定杆 (81) 固接的栓块 (82) 孔内, 将锁定杆 (81) 锁定在窗框下部 (13)。
5、根据权利要求 1所述的升降式防盗百叶窗,其特征在于间距控制装置是由齿轮(61)、 调向齿轮 (62)、 复位弹簧 (63)、 棘杆 (64)、 拨动杆 (65)、 棘轮 (66)、 与棘轮 (66) 固 接的齿轮(67)和轴承支座(68)组成, 齿轮(61)和齿轮(67)的中心距等于两栅栏杆(76) 之间的距离, 锁定杆 (81) 两端接头 (712) 与其余栅栏杆 (76) 两端接头 (75) 皆为与升
降螺旋杆(21) (25)啮合的螺母时, 在升降螺旋杆(21) (25)上部无螺纹轴颈段与螺纹段 交界处(714) 的窗框两侧 (12) (14) 内壁上安装间距控制装置, 其齿轮(61) 的轴心与升 降螺旋杆(21) (25)上部无螺纹轴颈段与螺纹段交界处(714)处于同一水平位置, 在前一 个栅栏杆 (76) 下降到额定间距时, 该栅栏杆 (76) 的两端接头 (75) 侧平面齿条 (713) 触碰到间距控制装置中的拨动杆(65), 使棘杆(64)脱离棘轮(66)而让齿轮(67)转动, 从而通过调向齿轮(62) 带动齿轮(61)转动, 而齿轮(61) 与后一个栅栏杆(76) 的两端 接头 (75) 侧平面齿条 (713) 啮合, 导致其与前一个栅栏杆 (76) 按额定间距同步下降, 当前一个栅栏杆(76)下移脱离拨动杆(65) 时, 棘杆(64)在复位弹簧(63) 的作用下重 新卡住棘轮 (66), 以避免其它栅栏杆 (76) 下滑到升降螺旋杆 (21) (25) 上的螺纹段上。
