A first return extends from the first flange toward the second flange parallel to the web, and a second return extends from the second flange toward the first flange parallel to the web. The axle hanger is easier to install and access in the event a hanger spring needs replacement, and the hanger can be more stably secured to the axle.

Abstract: A trailer frame includes a drawbar and a coupler connected to the drawbar through a pair of flexible and resilient connections operably disposed between the drawbar and the coupler and configured to absorb shock and vibration imparted to the drawbar and the coupler while the trailer is towed.

Abstract: An awning system includes a housing connectable to a rear of a vehicle and an awning canopy extendable from and retractable into the housing. In an embodiment, a plurality of marker lights is integrated with the housing and oriented to project light in a rearward direction when the housing is attached to the rear of the vehicle. In another embodiment, a rear-facing camera is integrated with the housing and oriented to have a field of view covering an area rearward of the vehicle and below the canopy.

Abstract: A lift assist device for a slide-out room includes a base and a floor support having a fixed portion, a deflecting portion, and a biasing member disposed between the base and the deflecting portion. When the slide out room is in an extended position, the weight of the room deflects the deflecting portion, thereby compressing the biasing member. As the slide-out room is being retracted from the extended position, the biasing member decompresses, thereby facilitating lifting of the slide-out room.

Abstract: An operating mechanism for a ramp door includes a door actuation system and a limit stop system. The actuation system is connected between the door and a frame or the vehicular structure directly and is operable to pivot the door between closed, deck, and ramp positions. The limit stop system selectively limits the pivoting of the door to a range between the closed and deck portion or to a range between the closed and ramp positions.

Abstract: A method and device for halting the extension or retraction of a retractable awning comprises a sensor coupled to a processor that commands awning extension and retraction. The sensor senses a motion parameter, such as acceleration, which is associated with extension or retraction motion of a retractable awning and generates corresponding respective extension or retraction motion parameter signals. The processor calculates an acceleration rate of change and/or a tilt angle from the motion parameter signals received from the sensor, and halts awning extension or retraction by generating and sending a stop signal when the acceleration rate of change or tilt angle meets at least one predetermined criterion.

Abstract: A platform twist mitigation apparatus operable to extend jacks into engagement with a surface disposed below a platform carrying the jacks, and to alternately extend and retract the jacks to change platform attitude relative to the surface. Tilt sensors are supported at spaced locations on the platform. An electronic control module is programmed to detect a platform twist condition in response to angle data received from the tilt sensors and to mitigate the platform twist condition by operating or modifying the operation of the jacks.

Abstract: A ramp door and door frame include a rail kit that deploys automatically when the door is opened and collapses automatically when the door is closed. The door is supported by a cable mechanism when the door is opened. The cable mechanism causes an end rail to pivot up and away from the door when the door is opened and down and toward the door when the door is closed. The end rail cooperates with a door frame to deploy flexible side barriers when the door is opened and to collapse the side barriers when the door is closed.

Abstract: A cable-operated mechanism for actuating a slide-out room includes a column, an endless chain loop disposed with the column, first and second drive blocks engaged with the chain loop, and first through fourth cables attached at first ends thereof to the drive blocks. The cables are attached at second ends thereof to inboard and outboard ends of a slide out room. Operation of the chain loop in a first direction tensions the cables attached to the inboard end of the room and slackens the cables attached to the outboard end. Operation of the chain loop in a second direction has the opposite effect.

Abstract: An expandable pontoon boat includes a center section, a first side section, and a second side section. First and second telescoping assemblies connect the first side section to the center section, and third and fourth telescoping assemblies connect the second side section to the center section. The telescoping assemblies may be extended and retracted to extend and retract the first and second side sections from the center section, thereby widening and narrowing the boat, respectively.

Abstract: A structure such as a toy hauler recreational vehicle includes a bed lift that moves a bed vertically between a lowered position, a raised position, and an upright position.
