    • The present invention discloses an emergency ladder equipment. Such an emergency ladder equimpment is mounted on the outside wall of the top floor of buildings. The emergency ladder equipment substantially comprises a number of ladder members which are stored in a storage case in a stacked or folded manner except for an emergency case, wherein the storage case is mounted on the outside wall of buildings. Each ladder member is connected by a connecting device to the subsequent ladder member. Furthermore, the bottom end of each ladder member is supported by a support stay disposed in the storage case. By releasing the support stay, each ladder member slides down one after another in series while being connected by a plurality of connecting devices to form a complete ladder which is installed along the outside wall of the building.
    • 本发明公开了一种应急梯设备。 这样一个紧急梯子平台安装在建筑物顶层的外墙上。 紧急梯设备基本上包括多个梯形构件,除了紧急情况外,堆叠或折叠方式存储在存储箱中,其中存储盒安装在建筑物的外壁上。 每个梯构件通过连接装置连接到后续的梯构件。 此外,每个梯构件的底端由设置在存放箱中的支撑支撑件支撑。 通过释放支撑撑杆,每个梯子构件在被多个连接装置连接的同时一个接一个地下降,以形成沿建筑物的外壁安装的完整的梯子。

    • A portable folding cart can be collapsed into a compact storage assembly. The base of the cart is a generally rectangular platform for supporting items to be transported. A plurality of wheels are mounted to the underside of the platform. The platform has a right side member and left side member, each of the side members being pivotally foldable at a joint along the length of the side member. A plurality of cross braces join the side members to each other, each cross brace also being pivotally foldable at a joint along the length of the cross brace. At the pivot hinge of each cross member, a spring is provided to bias the cross brace into its open position. A handle is attached to the platform and the handle has a pair of upright members, each having a plurality of telescoping segments. The right side upright member is pivotally attached to the right side member of the platform and the left side upright member is pivotally attached to the left side member of the platform. Upper and lower cross members complete the handle and are pivotally attached to the upright members.
    • 便携式折叠车可以折叠成小型存储组件。 推车的底座是用于支撑要运输的物品的大致矩形的平台。 多个车轮安装在平台的下侧。 平台具有右侧构件和左侧构件,每个侧构件沿着侧构件的长度在关节处可枢转地折叠。 多个交叉支架将侧部构件彼此连接,每个横向支架也可沿着十字支架的长度在关节处可枢转地折叠。 在每个横向构件的枢转铰链处,提供弹簧以将交叉支架偏置到其打开位置。 手柄附接到平台上,手柄具有一对直立构件,每个具有多个伸缩段。 右侧直立构件可枢转地附接到平台的右侧构件,左侧直立构件枢转地附接到平台的左侧构件。 上和下横向构件完成把手并且枢转地附接到直立构件。
