摘要： A trailer hitch (20) for attachment onto a motor vehicle for pulling a trailer. The hitch (20) consists of a pair of forward and aft mounting brackets (22 and 24) that are connected into existing holes in the vehicle's frame. Each mounting bracket has flanges (22′ and 24′) with the aft brackets (24) having thru-holes (26) arranged in a bolt circle array. The pair of forward mounting brackets (22) are connected to the aft mounting brackets (24) for length adjustment of the trailer hitch relative to the hitch position on the motor vehicle. The height of the trailer hitch (20) is regulated by the right side up or upside down position of the aft mounting brackets (24) properly orienting the thru-holes. A box hitch (44) is adjustably attached for width regulation onto the thru-holes of the aft mounting brackets (24) by inserting arms (30) into a tubular sleeve (50) of the box hitch at an appropriate distance. A receiver box (48) is connected on the bottom of the tubular sleeve for receiving a hitch ball mounted on a trailer ball mount.

摘要： A bolt-on, adjustable vehicle side step for a sports utility vehicle, pick-up truck or four wheel drive vehicle utilizing a pair of rocker panel attaching brackets (20) with an outward-extending integral male cog gear (22) that fastens onto a vehicle rocker panel. A pair of arms (34) having a female cog gear bore (36) and a step receiving hole (38) are juxtaposed on the bracket, with each male cog gear penetrating a bracket bore at an angle accommodating the configuration of a given vehicle and a desired step location. A pair of length adjustable legs (42) are nested together and attached to the brackets. Each pair of legs adjustably expand between the vehicle's frame and the brackets, thus forming an unyielding, compressible rigid structure. A step platform (64) is disposed within each connecting arm step receiving hole on each end such that the platform spaces the arms apart and provides a convenient footstep to assist a person who is entering or exiting the vehicle.

摘要： A two-position collapsible canopy assembly (10) is designed to be attached to the side rails (15) of a pickup truck (11). The assembly basically consists of a fore hard shell (12) that attaches to the rear of the truck cab, an aft hard shell (14), and a flexible canopy (16) therebetween that is supported by a plurality of ribs (22). The aft hard shell (14) and the ribs (22) are slidably disposed upon a pair of tracks (64) that are supported on the truck's side rails (15). The assembly (10) may be placed in a fully extended position or in a retracted position. When in the retracted position a security mid-gate (70) and mid-gate liner (72) may be attached below the aft hard shell (14) that provides a secure enclosed area into which items may be stowed. The mid-gate liner (72) affixed to the top of the corrugated truck bed deck (21) within the enclosed area allows the stowed items to remain dry in the event of inclement weather.

摘要： A vehicle-to-trailer light-connection verification tester (10) designed to be located within a towing vehicle (20), a towed trailer (30) or within a cable adapter (24) that is connected between the vehicle (20) and the trailer (30). The tester (10) features an electronics circuit (12) that includes a plug (P1), a receptacle (J2), a three-position mode switch (S1), a plurality of isolation diodes (D1-D4), and a loudspeaker (LS1). The mode switch (S1) has a vehicle test position V, a trailer test position T, and a normal lighting position N. When the switch (S1) is in the vehicle test position the rear vehicle lights are tested and when the switch (S1) is in the trailer test position (T) the rear trailer lights are tested. If each light in either the vehicle (20) or the trailer (30) is operational the loudspeaker (LS1) produces an audible sound. Conversely, if a particular light is not functioning no sound is heard. Thus, if there is a lighting problem a determination can be easily made if the problem is in the vehicle or in the trailer.

摘要： A wheel cover (20) that simulates a high profile automotive wheel and tire. The wheel cover (20) includes a base mounting plate (26) that is removably attached to a wheel (22) using conventional methods. A face plate (38), which is configured to partially cover the tire sidewall as well as a central portion of a wheel, is positioned on top of the base mounting plate (26). The mounting plate (26) is attached to the face plate (38) in a spring-loaded manner, which continually urges the face plate (38) to be in contact with the side wall of the tire (24). The spring-loading arrangement permits the face plate (38) to yield when the tire bulges due to weight induced distortion or road hazard impact. The face plate (38) gives way at the tire bulge and yet retains contiguous engagement with the tire. When attached, the face plate (38) extends outward from the wheel's outer perimeter and over a portion of the tire's sidewall, thus producing the appearance of a high profile wheel and tire.
