20140144729 | ROPE ARRESTING APPARATUS - A rope arresting apparatus for use with a rope having a first end and a weighted second end is disclosed. The rope arresting apparatus includes a cam portion for exerting frictional force on the rope and a pinching portion. The cam portion has a resting position and a pinching position. At the resting position, the cam portion is in frictional contact with the rope when the tension on the weighted second end of the rope is less than or equal to tension on the first end of the rope. A pinching point is formed when the cam portion at the pinching position engages the rope against the pinching portion. | 05-29-2014 |
20110067323 | BREAKAWAY UTILITY POLE WITH DECORATIVE BASE COVER - A breakaway pole installation includes a vertical pole having an anchored lower section anchored to a foundation and including a breakaway device for fracturing upon an impact of predetermined force. A decorative cover extends around the pole's lower section. The cover includes a lower foot and an upper lip. The pole includes an outward bump-out situated within the cover. The bump-out includes an energy transfer portion spaced below the cover's lip and above the cover's foot for transferring impact energy from the cover to the pole. The energy transfer portion has a height extending at least 60 mm above and 60 mm below a point of impact disposed about 450 mm above the foundation. The energy transfer portion has a maximum horizontal spacing from the cover of up to about 6 mm. | 03-24-2011 |
20100281786 | EMBEDDABLE BREAKAWAY UTILITY POLE - An embeddable breakaway utility pole comprises separate upper and lower aluminum pole pieces, wherein the lower pole piece is to be embedded below ground surface. The upper and lower pole pieces are interconnected by a weld which defines a breakaway zone enabling the upper pole piece to break off the lower pole piece in response to vehicular impact. The weld can be connected to a backer ring which provides a guide surface that axially aligns the pole pieces. Alternatively, the pole can be formed of a single pole piece which is welded between its ends to form a weakened region that defines the breakaway zone. | 11-11-2010 |
