    • A mobile scaffolding (10) for elevating a worker (not shown) above a floor or ground surface (S) is disclosed. The scaffolding (10) broadly includes a pair of frames (12) and (14), a platform (16) supported by the frames (12,14), a pair of casters (18, 20) and (22,24) rollably supporting a respective one of the frames (12,14), and a brake assembly (26, 28,30, and 32) associated with a corresponding one of the casters (18,20,22,24), respectively. The inventive brake assemblies (26,28,30,32) enable the worker supported on the platform (16) to selectively activate and deactivate the respective brake assemblies (26,28,30,32) from the platform (16). This enables the worker supported on the platform (16) to deactivate the brake assemblies (26,28,30,32), reposition the scaffolding (10), and then reactivate the brake assemblies (26,28,30,32) without requiring the worker to dismount from the platform (16).
    • 公开了一种用于升高地板或地面(S)上方的工人(未示出)的移动脚手架(10)。 脚手架(10)广泛地包括一对框架(12)和(14),由框架(12,14)支撑的平台(16),一对脚轮(18,20)和(22,24) 支撑相应的一个框架(12,14)以及与相应的一个脚轮(18,20,22,24)相关联的制动组件(26,28,30和32)。 本发明的制动组件(26,28,30,32)使得支撑在平台(16)上的工作人员能够从平台(16)选择性地启动和停用相应的制动组件(26,28,30,32)。 这使得支撑在平台(16)上的工作人员能够停用制动组件(26,28,30,32),重新定位脚手架(10),然后重新启动制动组件(26,28,30,32)而不需要 工人从平台下车(16)。

    • A mobile scaffold (10) having bi-axially rotatable casters (22–28) and including brake assemblies (30 and 32) associated with the casters (22–28) is disclosed. The inventive brake assemblies (30,32) enable an elevated worker to selectively control the mobility of the scaffold (10) and each broadly includes shiftable brake stop subassemblies (74 and 76), a brake housing (72) adjustably connected to a respective scaffold frame (12,14) and shiftably connected to the brake stop subassemblies (74,76), and an actuator (78) adjustably connected to the housing (72) and configured to shift the brake stop subassemblies (74,76) into and out of braking positions. When in the braking position, the brake stop subassemblies (74,76) prevent the respective casters (22–28) from rotating about both axes. The actuator includes cables (180,182) for interconnecting brake stop subassembly and the handle in one embodiment and a plunger (308,406) in other embodiments. Preferred alternative embodiments are disclosed that include pivotal linkage subassemblies (328,430) for intercommunicating the plunger and the brake stops.
    • 公开了一种具有双轴可旋转脚轮(22-28)并包括与脚轮(22-28)相关联的制动组件(30和32))的移动式脚手架(10)。 本发明的制动组件(30,32)使得升高的工作人员能够选择性地控制脚手架(10)的移动性,并且每个广泛地包括可移动的制动停止子组件(74和76),可调节地连接到相应支架的制动器壳体(72) 框架(12,14)并且可移动地连接到制动停止组件(74,76),以及致动器(78),可调节地连接到壳体(72)并且构造成将制动止动组件(74,76)移入和移出 的制动位置。 当处于制动位置时,制动止动组件(74,76)防止相应的脚轮(22-28)围绕两个轴线旋转。 致动器包括用于在一个实施例中用于互连制动止动子组件和把手的电缆(180,182),在其它实施例中包括柱塞(308,406)。 公开了优选的替代实施例,其包括用于使柱塞和制动器止动件相互连通的枢转连杆组件(328,430)。
