Abstract: A hitch pin assembly includes a hitch pin, a lock housing and a magnet on the lock housing. The magnet releasably attaches the lock housing for rotation around an aperture through the receiver tube. A plunger in the lock housing extends through the magnet and into the receiver tube. When a shank of a hitch assembly is inserted into the receiver tube and apertures on the shank and receiver tube align, the plunger extends through the apertures and holds the shank in position. A hitch pin is inserted through the opposite side of the receiver tube and into the lock housing. Flat exterior surfaces on the hitch pin are positioned between flat interior surfaces in the lock housing and hold the hitch pin against rotation as a rod in the lock housing is rotated into the hitch pin securing the rod and hitch pin together.

Abstract: An anti-rattle device for a trailer hitch assembly is attached to a receiver tube of the trailer hitch assembly and remains attached to the receiver tube both when a shank of the trailer hitch assembly is inserted into the receiver tube and the shank is removed from the receiver tube. With the device attached to the receiver tube the shank is inserted through the device and into the receiver tube. The device can then be manually adjusted to push the shank in the receiver tube downward against a bottom interior surface of the receiver tube and to one side against a side interior surface of the receiver tube and thereby eliminate rattle between the shank and the receiver tube.

Abstract: A hitch pin assembly includes a hitch pin, housing and shoulder bushing. The bushing is permanently attached in an aperture of a receiver tube and the housing is rotatably attached to the bushing. A plunger in the housing extends through the bushing and projects into the receiver tube. When the shank is inserted into the receiver tube the plunger tip catches the aperture of the shank, holding the shank in a position in which the pin-receiving apertures on the receiver tube and shank are aligned. The hitch pin is then inserted from one side of the receiver tube and into the bushing. A plunger in the housing translates along a projection in a track of the plunger to reveal the projection to the hitch pin tip and place it into position for engagement with the inserted hitch pin. The engagement holds the shank and eliminates rattling.

Abstract: An enclosure structure in the form of a security cage is attached to a top surface of a cargo carrier as the security cage is assembled on the top surface of the cargo carrier. The assembled security cage enclosure structure encloses and secures objects supported on the cargo carrier in an interior volume of the security cage enclosure structure. The construction of the security cage enclosure structure eliminates the need for separate fastener assemblies to attach the assembled security cage enclosure structure to the top surface of the cargo carrier.

Abstract: An extendable object support rack for a vehicle includes a rack rod that is removably attachable to the vehicle and has an object support on the rack rod that is removably attachable to an object to support the object on the rack rod, and an extension rod that is removably attachable to the rack rod without the use of tools and also has an object support on the extension rod that is removably attachable to an object to support the object on the extension rod. An opening in the forward end of the extension rod is configured for receiving a rearward end of the rack rod in the opening, and a pin in the opening is positioned to extend into a hole in the rearward end of the rack rod to secure the extension rod to the rack rod without the use of tools.

Abstract: And angularly adjustable object support rack or bicycle support rack for a vehicle is constructed with a first rod and a second rod connected by an adjustment structure that enables the first rod and the second rod to be adjusted to a folded over configuration that occupies less space when storing the bicycle rack. The adjustment structure also enables the first rod and second rod to be adjusted to a right angle orientation that reduces the extent the support rack extends from the rear of a vehicle to which it is attached. The adjustment structure enables the first rod and second rod to be adjusted to where the second rod is aligned with the first rod for attaching bicycles on the support rack. The adjustment structure further enables the second rod to be adjusted to a downward tilted orientation providing clearance between the vehicle and the attached support rack.

Abstract: A valve assembly includes a valve body defining a main flow pathway (28) and a bypass channel (52) for bypassing the main flow pathway. A ball (20) is located in the main flow pathway and is moveable between an open position and a closed position. When the ball is in the open position, an open pathway through the ball fluidly completes the main flow pathway to provide an ordinary flow, and when the ball is in the closed position the ball blocks the main flow pathway. A pressure relief feature (50) is disposed in the bypass channel (52), and the valve body further defines a pressure relief passage (62) comprising a clearance between an outer surface of the ball (20) and the valve body. The pressure relief feature (50) permits a relief flow from the bypass channel (52) through the pressure relief passage (62) around the ball (20), and to the outlet (24) to relieve excess pressure in the connecting inlet piping (22).
