Abstract: A tonneau cover for selectively enclosing a space within a cargo box. The cover has an elongate channel laterally extending between a proximate end located proximate a side edge of the cover and a distal end at which the channel terminates. The cover includes a clamp mechanism slidably engaged with the channel, and the clamp mechanism includes a handle, a block member slidably received in the channel, an elongate rod member coupled to the handle, and a latch or hook member connected to the rod member. The latch member is moveable between a clamped position for operatively engaging a portion of the cargo box and a released position for spacing the latch member from and placing the latch member out of operative engagement with the cargo box. The handle and rod member are positioned in the channel in the clamp mechanism stowed position.

Abstract: A protective cover assembly for covering a space defined by at least one wall. The protective cover assembly includes a plurality of rails coupled to one another to form a frame for securing a material over the space. At least one support bow spans the space to support the material. Clamp mechanisms are coupled to the ends of the support bow for securing the protective cover over the space. The clamp mechanisms include a latch member for engaging the wall and a handle for biasing the latch member against the wall. The clamp further includes a shaft for interconnecting the support bow to the frame. A collar is disposed over the shaft for guiding the handle and the latch member between an operational position and a stowed position along the shaft.

Abstract: A folding tonneau cover including a first substantially rigid panel having a laterally-extending front edge at least partially defined by an elongate edge rail, and a second substantially rigid panel having a laterally-extending rear edge at least partially defined by an elongate edge rail, the first and second panels having opposed exterior and interior sides. The first and second panels substantially lie in a plane when the cover is unfolded, the first and second panel exterior sides generally facing in a direction away from a first side of the plane when the cover is unfolded, the first and second panel exterior sides adjacently superposed when the cover is folded. The cover includes a hinge assembly having substantially rigid first and second portions pivotally connected together along a first pivot axis located on the one side of the plane, the hinge first portion affixed to the first panel edge rail, the hinge second portion affixed to the second panel edge rail.

Abstract: An adjustable keyboard support mechanism includes a mounting bracket for attachment to a support surface, a platform for supporting a keyboard thereon, a support arm operably connected to the mounting bracket and the platform, and a locking mechanism for restricting height adjustment of the platform with respect to the support surface. The locking mechanism includes a center arm pivotable with respect to the platform and slidable with respect to the mounting bracket, a plurality of frictional members sandwiching and frictionally engaging the center arm, thereby restricting the sliding movement of the center arm with respect to the mounting bracket, and a wedge assembly actuable by pivoting movement of the platform and engageable with the frictional members to both restrict and allow height adjustment of the platform relative to the support surface.
