Vacuum cleaner

A cleaning tool having a height adjustment mechanism which may be overridden to prevent damage to the cleaning tool in the event an excessively high force is applied to an exterior surface of the cleaning tool. The height adjustment mechanism forms an overrideable clutch having a manually adjustable thumbwheel, a biasing member and a clutch member. The height adjustment assembly is operably associated with a roller assembly which supports the cleaning tool on a work surface at a desired height above the work surface. The application of a predetermined excessive force to an exterior surface of the cleaning tool causes the height adjustment assembly to be de-clutched to allow the lower surface of the cleaning tool to come in contact with the work surface, thereby preventing damage to the various internal components of the cleaning tool.

A cleat for attachment to a device having a power cord. The cleat includes a center support attached to the device for selectively retaining the power cord adjacent to the device. A pair of cord retaining arms extend from the center support in opposite directions. The pair of cord retaining arms are supported by the center support for rectilinear movement between an extended position forming a cord wrapping pocket between each of the arms and the device for retaining the power cord about the center support and in the pockets and a retracted position closing the arms for releasing the power cord from the center support. In a preferred embodiment, the cleat further includes an intercoupling mechanism interconnecting the pair of arms for synchronous movement of one of the arms in response to the rectilinear movement of the other arm. The synchronous movement is movement in a direction opposite and through the same distance as the other arm. The intercoupling mechanism includes a first rack attached to one of the arms, a second rack attached to the other arm, and a ring gear meshed between the first rack and the second rack.
