Abstract: A hinge assembly for connecting an appliance door to an appliance frame includes a claw and a channel pivotally connected to the claw. A single link member is pivotally connected to the claw, and the link member defines first and second contact surfaces. The second contact surface defines an operative portion and a break-away portion separated from the operative portion by a peak. A spring is operably engaged between the link member and the channel. A link control member is connected to the channel and contacts the second contact surface of the link member. The channel is movable from a first operative position in a first direction on arc of 90 degrees or less to a second operative position where the link control member is in contact with the operative portion of the second contact surface of the link.

Abstract: An improved oil well drilling rig structure (10) is provided. The drilling rig structure (10) includes a base (32) for placement on the ground at a well site. The base (32) includes first and second ends (32a, 32b). A drill floor (14) supported on a floor box (12) having first and second ends (12a, 12b) is disposed parallel to and adjacent the first end (32a) of the base (32). The floor box (12) is coupled to the base (32) by spaced apart parallel legs (76, 78) each pivotally attached between the upper box (12) and the base (32) for elevating the floor (14) from a low position adjacent to the first end (32a) of the base (32) to an elevated position medially between the ends (32a, 32b) of the base (32) and located above the base (32) by rotation of the legs (76, 78) towards a vertical position. The structure (10) further includes a tensile link (40) having first and second ends (40a, 40b).
