HINGED LID HANDLING TOOL
20180229990 · 2018-08-16 · ·

An ergonomic apparatus for handling a hinged lid that reduces force required to open the hinged lid and bending by a user, maintains the lid in an open position to prevent accidental closure of the lid, and assists with closing the lid. The apparatus has a horizontal member with an attachment means for removably coupling the apparatus to the hinged lid, a vertical member extending from a proximal end of the horizontal member, and a handle in operable communication with the vertical member. The vertical member and handle are configured relative to the horizontal member such that when the vertical member is positioned on a flat surface, the handle is raised above the flat surface by about 10 to 25 and the hinged lid is maintained in an open position having an angle greater than 90 relative to an opening the hinged lid was covering.

PRY BAR HAVING A RETRACTABLE END GUARD
20240375926 · 2024-11-14 ·

A pry bar includes a member having a first end, a second end, and an intermediate portion, a prying member arranged at the second end; and a retractable end guard moveably mounted at the second end. The retractable end guard is selectively configurable between a first position in which the retractable end guard covers the prying member and a second position in which the prying member is exposed.

PORTABLE MANHOLE COVER MOVING ASSEMBLY AND METHOD FOR MOVING A MANHOLE COVER
20180057334 · 2018-03-01 ·

A manhole cover moving assembly and method for moving a manhole cover works to lift, lower, rotate, extend, retract, and laterally displace a manhole cover over a short distance and in difficult to access areas. The moving assembly detachably attaches a hitch to a mobile mount for portability. The moving assembly provides a mast and a shaft that operate at adjustable relative to create mechanical advantages while moving the manhole cover. A telescoping support arm adjusts the angle of the shaft relative to the mast. The shaft carries a pulley apparatus and a cable that suspends the manhole cover. The mast rotates about a hitch. The shaft pivots about the mast. The shaft also extends and retracts. Further, as the angle of the shaft is changed through manipulation of the telescoping support arm, the mechanical advantage is increased for facilitating movement of the manhole cover.
