Abstract: A liner assembly for a protective helmet has a wrap-around pad inside the helmet with plural circular cells spaced along a curved line, at least one additional cell at each end of the line and one additional cell located off the line. A crown pad removably engageable in a crown of the helmet and two L-shaped jaw pads removably engageable to jaw flaps of the helmet. Each cell includes an outer sheet welded around its perimeter to the perimeter of an inner sheet, each inner sheet engaging a player's head and defining one enclosure for each cell. Each cell containing a foam cushion and multiple spaced apart hollow protrusions contacting the inside of the helmet. Each protrusion has an open large diameter base near the cushion and flat smaller diameter peak engaging the helmet. Each protrusions also having a conical side wall tapering from base to peak.

Abstract: A liner assembly for a protective helmet which includes a wrap-around pad designed to be engaged to the inner surface of a helmet. The wrap-around pad has multiple substantially circular cells spaced along a curved line around the inner surface. The assembly also has a crown pad and two jaw pads. Each jaw pad is an cell L-shaped cell. Each cell is made of an inner sheet, an outer sheet and multiple, outwardly-projecting hollow protrusions.

Abstract: A football helmet has a shell with a top portion having a raised central channel at least at one of a front area and a top area of the top portion of the shell, with a plurality of elongated vent openings on each side of the channel, the vent openings being spaced from each other on each side of the channel, from front to back, along the helmet shell, the sides of the helmet having earholes and sloped banks abutting the earholes in a wedge configuration.

Abstract: A helmet having a shell configured to fit about a head of a wearer of the helmet. The shell includes a top portion that defines a front edge and a bottom portion adjoining the top portion. The bottom portion defines a first side edge integral with a first end of the front edge and a second side edge integral with a second end of the front edge. The front edge, first side edge, and second side edge define a segment of a circumference of the shell. The helmet includes a faceguard comprising a faceguard assembly formed in a substantially closed loop. A top portion of the faceguard assembly overlies the top portion of the shell and substantially overlies and coincides with an entire shape of the front edge. At least a segment of a top portion of the faceguard assembly makes direct contact with the top portion of the shell.

Abstract: A cleaning implement for removing debris from a surface comprises a handle, a mop head, and a joint connecting the handle and mop head; wherein the joint is adjustable and lockable. The joint allows the angle between the mop head and the handle to be adjusted appropriately and then locked into place. Another embodiment of the present cleaning implement comprises a handle and a mop head, wherein the mop heads comprises one or more gliders to facilitate the ability of the cleaning implement to glide smoothly across the surface being cleaned. Methods of removing debris comprise the step of contacting the surface with a cleaning implement of the present invention.
