    • An easy-to-construct modular wheelchair ramp with reliable dimensional stability in excess of all current regulatory requirements is provided. Such a modular device allows for a variety of ramp materials to be incorporated therein on demand as well as the utilization of any desired ramp pitch without any need to adjust (let alone actually use) connecting brackets and/or under-section supports. The double-channel stringer configuration thus allows for support legs to easily connect and move along such a component for facilitated set-up. Additionally, the double-channeled structure allows for any handrail materials to be properly and easily secured thereto. The stringer alone, as well as the overall modular ramp structure, are encompassed within this invention. The method of constructing such a wheelchair ramp is also envisioned within the invention.
    • 提供了一种容易构造的模块化轮椅坡道,其尺寸稳定性可靠性超过目前的所有法规要求。 这种模块化装置允许根据需要将各种斜坡材料并入其中,以及利用任何所需的斜坡间距,而不需要调整(更不用说实际使用)连接支架和/或底部支撑。 因此,双通道纵梁构造允许支撑腿容易地沿着这种部件连接和移动以便于安装。 此外,双通道结构允许任何扶手材料适当且容易地固定到其上。 单独的纵梁以及整个模块化斜坡结构都包含在本发明内。 在本发明中也设想了构成这种轮椅坡道的方法。

    • A combination duct/extinguishing system includes a duct and plural sprinkler head assembly and mounting systems on the duct. Each sprinkler head assembly and mounting system includes port structure mounted on the duct defining a passageway into an area internally of the duct, sprinkler head structure having one end associated with a corresponding port structure, and another end associated with an extinguishing media, and collar structure for removable engaging the port structure and the sprinkler head structure to fixedly hold the sprinkler head in the area internally of the duct. Preferably, the collar structure includes two halves hingedly joined, each having wall structure defining a groove for receiving a portion of the port structure and the sprinkler head structure.
    • 组合管道/灭火系统包括管道和多个喷洒头组件和管道上的安装系统。 每个喷洒头组件和安装系统包括安装在管道上的端口结构,其限定通向管道内部的区域的通道,具有与相应端口结构相关联的一端的喷洒头结构,以及与灭火介质相关联的另一端, 用于可拆卸地接合端口结构和喷洒头结构,以将喷洒头固定地保持在管道内部的区域中。 优选地,套环结构包括铰接地连接的两个半部,每个具有限定用于接收端口结构的一部分和喷洒头结构的凹槽的壁结构。
