A receiver pin is provided for attaching a ball mount to a receiver on a vehicle. The receiver pin includes a body having an insertion portion and a retaining portion. The insertion portion is sized for insertion through aligned openings in the ball mount and the receiver. The retaining portion extends at least partially laterally from a proximal end of the insertion portion for limiting axial movement of the inserted body in a first direction. The insertion portion also includes a transverse re...

A lockout device for securing a toggle switch. The lockout device includes a body, a first clamping surface, a second clamping surface, and a cam. The first clamping surface and the second clamping surface are moveably coupled to the body and are positioned to define a slot for accommodating the toggle switch. The cam is rotateably coupled to the body. When the cam is rotated in a first direction, the cam moves the first clamping surface towards the second clamping surface.

A trailer/cargo alarm detects the proximity of trailer or cargo attached to a vehicle with an alarm system. If the trailer/cargo is moved out of proximity of the vehicle, the alarm system issues an alert. The proximity of the trailer or cargo may be detected, for example, by detecting the presence of the trailer lighting within the vehicle's electrical circuit, by dedicated hardwired sensors, or wireless detection apparatus.

A portable safe for assembly with an apertured member includes a safe housing and a safe door. The safe housing has an internal cavity extending to an access port, and at least one opening configured to align with at least one aperture of the apertured member. The safe door is securable to the housing to substantially block the access port. The safe door includes a locking mechanism having at least one locking member secured in a housing engaging position when the locking mechanism is in a locke...

An example presentation apparatus having a cabinet-like base and a surface coupled to the cabinet-like base and configured to hold an object. The cabinet-like base and the surface are configured to cooperate functionally with a function of the object. A portion of an air processing apparatus is disposed within the cabinet-like base and configured to move ambient air through the cabinet-like base to generate processed air. An exhaust structure is operatively coupled to the cabinet-like base and c...

Retractable cord reels are disclosed. The retractable cord reels include a housing portion and a spool disposed within the housing portion. The spool has an outer surface associated with an expansion chamber within the housing portion, an inner channel configured to hold a wound length of flat electrical cable and a passage extending between the outer surface and the inner channel. The retractable cord reels also include a flat electrical cable having a first portion disposed in the expansion ch...

A customizable towing hitch ball mount arrangement for a vehicle is provided. The arrangement includes a ball mount and a customizing element. The ball mount includes a proximal end for insertion into an opening in the hitch receiver, an elongated tube portion, a drop portion extending from the elongated tube portion and angled with respect to a length of the elongated tube portion, and a plate extending substantially horizontally from the drop portion. The drop portion includes at least one mou...

An assembly for restricting access to a coupler includes a body, a ball cavity engagement member; and a securing mechanism. The body is configured for engagement with at least one surface of the coupler. The body includes a coupler engagement portion. The ball cavity engagement member is movably coupled to the body and configured for engagement with a ball cavity of the coupler. The securing mechanism can fix the position of the ball cavity engagement member relative to the body such that the as...

Sensors and methods for detecting attachment to a surface are disclosed. The sensors include a housing having an inner surface, an outer surface and a passage extending through the housing. An elongated member or fastener extends though the passage and protrudes from the outer surface of the housing to attach the sensor to a surface. First and second electrical contacts are disposed within the housing so that when the sensor is attached to the surface an electrical path is formed between the fir...
