    Abstract: A delayed action door closer that delays a portion of the closing of a door for an adjustably determined period of time after the door has been moved to its fully open position. An interdependent hydraulic speed control system utilizes a delayed action speed control regulating valve which controls the closing speed of the door in the delayed action zone only, and whose speed cannot be adjusted faster than the main closing speed, but can be adjusted to provide a desired delay time prior to the door closing under normal regulation. The placement of the interdependent hydraulic system in the checking end of the closer allows the closer to have a fully adjustable independent backcheck.

    Abstract translation: 延迟动作门关闭器，其在门已经移动到其完全打开位置之后延迟门的关闭的一部分可调节地确定的时间段。 相互依赖的液压速度控制系统使用延迟动作速度控制调节阀，其仅在延迟动作区域中控制门的关闭速度，并且其速度不能比主闭合速度更快地调节，而是可以调节以提供期望的 在正常调节之前关门的延迟时间。 相互依赖的液压系统在靠近检查端的位置允许更接近地具有完全可调的独立反向检查。

    Abstract: A hinge including: a first leaf assembly accommodating a portion of a first panel having a first cut-out section, the first leaf' assembly including a first insert component which is tight fittingly receivable within the first cut-out section; a second leaf assembly, hingedly coupled to the first leaf assembly, for accommodating a portion of a second panel having a second cut-out section; one or more biasing components to bias the hinge toward a closed position; and a dampener to slow movement of the first and second leaf assemblies to the closed position, a first portion of the dampener is located within the first insert component and a second portion is configured to at least partially retract within the first insert component when coining into contact with the second leaf assembly during movement, a second portion of the dampener extends and retracts along an axis coplanar with the first panel.

    Abstract: A device to apply a rotational force to a spring of a rollup or overhead garage door counterbalancing mechanism. The device has a rotatable driven member mounted in a housing. The housing and the driven member have slots with an open end adapted to receive the shaft of the overhead garage door counterbalancing mechanism. A coupling member is configured to mount to the driven member and connect the driven member to the winding cone of a garage door spring to apply rotational force to the spring. The housing with the driven member may be connected to the body of an existing power tool in place of the original tool head, or, the housing may be permanently combined with a motor and transmission to provide a special purpose tool.
