Abstract: A device including a roller cage configured for connection to a frame of a paint roller. The roller cage includes a distal end cap having an outer wall. The roller cage also includes a roller cage body connected to the distal end cap, the roller cage body including a first side wall and a second side wall opposed to the first side wall. The first side wall and the second side wall radially extend less than a radius of the distal end cap. The roller cage also includes a crest disposed at least partially within the roller cage body and extending radially past the first side wall and the second side wall.

Abstract: A crate for agricultural products can include a base, a side wall, and a hinge mechanism pivotably connecting the side wall with the base such that the side wall is movable between a folded configuration and an erected configuration relative to the base. The hinge mechanism can include a hinge extending from the side wall. The hinge can include a rod. The hinge can further include a hinge receiver defined by the base. The hinge receiver may define a receiving area with an opening. The opening may be at a top end of the hinge receiver. The opening may define a minimum width of the receiving area. The rod of the hinge can be positionable into the receiving area via the opening.

Abstract: A pallet-dolly device convertible between a pallet and a dolly has a deck to which a set of dolly wheels are attached at a fixed height below the deck. A set of movable pallet skids are mechanically interlinked with the deck by a bistable skid displacement mechanism which assumes a first state biasing the pallet skids upwards towards a skid raised position and a second state in which the bistable skid displacement mechanism biases the pallet skids downwards towards a skid lowered position. Also described are embodiments allowing conversion from dolly to pallet by directly pressing downwards on a skid, and provision of a braked-dolly state through downward pressure of the skid against the ground and/or a skid-actuated wheel brake.

Abstract: A pallet-dolly device convertible between a pallet and a dolly has a generally rectangular deck to which a set of dolly wheels are attached at a fixed height below the deck. A set of movable pallet skids are moved by a skid displacement mechanism between a skid lowered position in which a ground contacting surface of the skid is lowered below a contact plane of the wheels to provide a pallet state of the pallet-dolly device, and a skid raised position in which the skid ground contacting surface is raised above the wheel contact plane to provide a dolly state of the pallet-dolly device. At least two pedals, accessible from two adjacent sides of the deck, are deployed to be operated by a user to activate the skid displacement mechanism.
