    Abstract: An expandable air filter. The air filter including a filter media assembly, an outer frame assembly, and at least one support member. The filter media assembly defines opposing, first and second major faces and a perimeter. The outer frame assembly is arranged about the perimeter. The support member is connected to the outer frame assembly and extends across the first major face. Further, the support member defines a line of separation at which the support member can be separated into first and second segment to permit expansion of the air filter. The filter media can form a plurality of pleats, with at least one pleat being free of bonding to the outer frame assembly. The unbonded pleat experiences expansion as the air filter transitions to an expanded state. The air filter can be configured for expansion in one or both of a length and width direction.

    Abstract: A flexible hook hanger comprises an elongate sheet of pliable backing, an adhesive layer and a hook element. The backing comprises first and second ends, a first zone positioned adjacent the first end, a second zone positioned adjacent the second end and a central zone positioned between the first and second zones. The adhesive layer is disposed on one side of the backing. The hook element is connected to the central zone. In one embodiment, the pliable backing comprises microstructured tape, and the adhesive layer comprises a pressure sensitive adhesive composition comprising one or more hydrocarbon block copolymers, and a polar phenolic tackifier. In another embodiment, at least one of the first and second zones includes a peel arrestor. For example, the first zone and the second zone have a first width and a second width, respectively, and the central zone has a third width that is less than at least one of the first width and the second width.

    Abstract: A hand held dispenser for dispensing sheet material from a roll. The dispenser includes a handle assembly, an elongated blade, and a support assembly. The handle assembly includes a hub rotatably mounted to a frame. The blade extends from the frame. The support assembly includes a bracket, a brace and a support hub. The bracket is attached to the blade apart from the frame and includes a guide track. The guide track provides first and second segments that combine to define a guide axis. A leading side of the brace is slidably mounted to the guide track along the guide axis. The support hub is rotatably mounted to a trailing side of the brace. In a locked state, the leading side is slidably disposed over the track first segment and cannot rotate. In an unlocked state, the leading side is over the track second segment and is allowed to rotate.

    Abstract translation: 一种用于从卷筒分配片材的手持式分配器。 分配器包括手柄组件，细长刀片和支撑组件。 手柄组件包括可旋转地安装到框架的轮毂。 刀片从框架延伸。 支撑组件包括支架，支架和支撑毂。 托架与框架相连，并且包括导轨。 导轨提供组合以限定引导轴的第一和第二段。 支架的前导侧沿引导轴可滑动地安装在导轨上。 支撑轮毂可旋转地安装到支架的后侧。 在锁定状态下，前导侧可滑动地设置在轨道第一段上并且不能旋转。 在解锁状态下，前导侧在轨道第二段上方并被允许旋转。
