Abstract: An exercise apparatus for performing two-handed exercises includes a frame to which weights are connected and a pair of hand grip assemblies with which the frame is moved by the user between two positions of movement during an exercise routine. Each hand grip assembly includes a ring and an elongated grip joined to so as to extend generally across the center of the ring. Each ring is pivotally connected to the frame in a manner which permits the ring to pivot relative to the frame about a pivot axis which is fixed in position relative to the frame and disposed across the ring and arranged generally perpendicular to the grip. When the frame is moved between two positions of movement with the hands grasped about the elongate grips, the rings are permitted to pivot relative to the frame to accommodate an adjustment in position of the wrists of the grasping hands.

Abstract: A hand grip assembly for a wheelbarrow handle shaft includes a handle having an elongate grip configured to be gripped by a hand along its length and along a grip axis. The handle is pivotally mounted on the handle shaft of the wheelbarrow for movement about a pivot axis which is oriented generally parallel to the support surface underlying the wheelbarrow and which is disposed closely adjacent to and generally perpendicular to the grip axis, approximately midway along the length of the grip.

Abstract: An expansion joint for settable compositions such as concrete and the like comprises a base portion which is embedded in the composition before it sets with its upper surface adjacent the surface of the composition, and a cover portion which is engagingly received in a slot defined by the removal of a portion of the upper surface of the base portion after the composition hardens around the base. The cover portion is sufficiently wide to cover gaps in the composition adjacent the edge of the base portion. Two or more base portions may be secured together to provide an expansion joint to variable depths in the composition.
