Patent number: 12146286Abstract: A selectively frictionally engaged hole cover for a bore hole cored from a paved surface that includes a cover plate configured to cover the bore hole and support vehicular traffic. An engagement mechanism is attached to the cover plate and extends down into the bore hole. The engagement mechanism is configured to be actuated by a user torque input that causes an engagement plate selectively shiftable relative to the cover plate to thereby shift an engagement member along a sloped wall and thus radially outwardly or inwardly, causing the engagement mechanism to selectively engage or disengage the wall of the bore hole. When the engagement member is in frictional contact with the hole, unintentional extraction of the engagement mechanism is prevented. The selectively frictionally engaged hole cover effectively provides a temporary cover for a bore hole in a road, parking lot, or other paved surface.Type: GrantFiled: January 24, 2024Date of Patent: November 19, 2024Assignee: Clover Equipment, LLCInventors: Mike Reardon, Kevin Reardon

Rotation of the hub in one direction causes the latching arms to engage the rim and tightly latch the cover to the rim while rotation of the hub in the opposite direction retracts the latching arms and frees them from the rim to enable removal of the cover from the opening. A shaft extends through the cover and is axially slidable and rotatable relative to it. The shaft is axially slidable relative to the hub and continuously engages it so that rotation of the shaft correspondingly rotates the hub. A handle fixed to the upper end of the shaft rotates the hub to activate the arms.Type: GrantFiled: February 1, 1979Date of Patent: June 16, 1981Inventor: Robert W. Sutton

Patent number: 4020778Abstract: A hatch cover for closing and sealing a hatch opening has radial latching arms connected at their inner ends to a rotatable arm-actuating hub on the bottom side of the cover at ball-and-socket connections and loosely connected to the cover near their outer ends. In one rotational position of the hub the arms overlap and apply clamping pressure to the rim of the hatch opening and in a second rotational position of the hub the arm-clamping pressure is released and the arms are retracted from the rim to enable removal of the cover from the opening. The hub rides on camming surfaces of the cover which are shaped so that as the hub rotates in a hatch-closing direction, the arms first extend over the rim of the opening and then pivot into clamping engagement with the rim about their loose connections to the cover, urging the cover through such connections into tight seated engagement with the rim.Type: GrantFiled: February 13, 1976Date of Patent: May 3, 1977Inventor: Robert W.

Patent number: 3934925Abstract: To meet the legal requirements for bus safety, all locking devices on entrance and emergency doors must be removed before the bus is placed in service. For that purpose, the ignition key is made part of a simple locking assembly that is used to lock the emergency door. The driver's obtaining the key to operate the bus engine, insures the unlocking of the emergency door. The unlocking of the entrance door is accomplished by an inside pivoted cam assembly, actuated by a locking handle on the outside of the bus. The unlocking pivoted cam assembly inside the bus, then entirely disengages the door controlling mechanism, which then has normal operating freedom.Type: GrantFiled: February 14, 1974Date of Patent: January 27, 1976Inventor: Joseph T.
