    摘要: A self-adjusting wrench having a handle and a jaw member rotationally attached thereto. A smoothly curved handle face opposes a planar face on the jaw member which adjusts for distance from the curved handle face by following a generally circular path around a pinned attachment of the jaw member to the handle. A spring or similar biasing device continuously urges the jaw member toward the handle thereby making the device self adjusting to the size of the object placed between the jaw member and the curved handle surface.

    摘要: The present invention provides a chair assembly having a support member defining a plurality of positioning stations separated by a predetermined vertical distance. A coupling element may be included that defines a first portion and a second portion, such that the first and second portions are pivotably coupled to one another. The coupling element may be engageable with one or more of the positioning stations of the support member. A foot ring may also be included, where the foot ring is engageable with the coupling element to be positioned at a desired height while being securely affixed to the coupling element and thus, the support member of the chair assembly.
