A hatch cover lock comprises a front member including a pair of flanges, a rear member positioned between the pair of flanges; a gap defined between front member and the rear member; a clamp defining a J-shaped cross-section in a plane normal to a length thereof, the clamp having one leg thereof disposed in the gap and having another leg thereof disposed parallel to an outer surface of the rear member and at a distance therefrom, a handle, a first pivotal connection between the handle and the front member, a gravity lock, a second pivotal connection between the gravity lock and the handle, and a weld-free connection between the main portion of the rear member and the main portion of the front member.

A multi-piece umbrella pole that includes first and second pole sections that are assembled into an elongate umbrella pole. The pole sections include an alignment notch and cross pin for facilitating assembly of the two pole sections. An outer sleeve includes a button assembly that can actuate a detent pin for coupling or decoupling the pole sections. The outer sleeve can also include an actuator for a tilt mechanism that angles a canopy portion of the umbrella assembly.

A corner piece is provided for interconnecting frame members. The corner piece includes a first plate member defining an inner face, an opposite outer face, a first side face, an opposite second side face, and an end face. The first plate member including a bolt-receiving bore therethrough. A second plate member defines an inner face contiguous with the inner face of the first plate member, an outer face, a first side face, an opposite second side face, and an end face. The second plate member includes a bolt-receiving bore extending between the inner face and the outer face thereof along a first axis generally parallel to the inner face of the first plate member.
