The inventive disclosures described herein pertain to an improved folding trailer that, in many embodiments, is comprised of an improved swivel jack to more-easily aid in safe trailer-folding operations, a hinged trailer tongue, an integral winch with an extended flexible coupling shaft, and an external or onboard rotational power source to drive the winch. More specifically, this folding-trailer configuration minimizes the physical exertion required of a user to fold or unfold the trailer, as well as significantly reduces the potential for serious user injury during the folding/unfolding process. The improved folding trailer also features foldable cargo-containment sides and multi-positionable tailgate, as well as removable/configurable cargo-carrying racks/rails.

A mobile photography studio for photographing objects. The studio has a main trailer body having an internal volume defined by a roof, a floor, a front wall, a rear wall, and two side walls. A control computer controls an expansion of the sidewalls of the trailer, and optionally the roof, to expand the internal volume of the trailer. A turntable, which is disposed on the trailer floor supports and rotates the object based on commands from the control computer. At least one camera takes photographs of the object on the turntable based on commands from a camera control computer. A plurality of lights illuminate the object on the turntable based on commands from the control computer. The camera control computer controls the camera(s), and stores and processes the photographs.

An extendable trailer assembly configured to be towed by a vehicle. The extendable trailer assembly includes a first compartment including a floor, a pair of opposing sidewalls, and a ceiling. The first compartment is configured to be coupled to a trailer hitch of the vehicle. The extendable trailer assembly also includes a second compartment including a floor, a pair of opposing sidewalls, and a ceiling. The extendable trailer assembly also includes a slide assembly slidably coupling the second compartment to the first compartment such that the second compartment is slidable relative to the first compartment between a fully extended position and a fully retracted position in which the first compartment is at least partially housed inside of the first compartment. The extendable trailer assembly is free of road-capable wheels for transport by the vehicle.

A safety trailer including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein each wall section has a lower bracing section comprising a single horizontal beam, two diagonal braces and a plurality of cross-braces, to allow workers in the protected work area to access a portion of the area under the wall section.

A trailer has a three-section flat bed in which the front and rear sections fold onto the middle section. The trailer has an airbag suspension system and one wheel on each side. When the airbags are deflated, the entire flat bed forms a ramp for loading and unloading. When the airbags are deflated and the flat bed is folded, the trailer can be stored vertically while resting on its wheels.

A modular compact trailer for a utility terrain vehicle or an all-terrain vehicle that includes a trailer frame with a bed and a plurality of walls, at least two axle retention boxes, at least two axles, and a tongue. The at least two axles that are removably couplable to a corresponding axle retention box. The tongue is removably couplable to a front end of the trailer. The modular compact trailer includes a storage configuration in which the trailer frame is upright with components stored within the trailer frame. The modular compact trailer includes a transportation configuration in which the trailer frame fits within a bed of a standard truck bed with components stored within the trailer frame. The modular compact trailer includes an assembled configuration, the at least two axles are attached to the corresponding axle retention box and the tongue is attached to the front end of the trailer.

Provided is a vehicle for ultrasound-guided interventional operation, including: a vehicle body, wherein the vehicle body is provided with a carriage; an operating table arranged in the carriage; an operating lamp arranged in the carriage; an ultrasonic device arranged in the carriage, wherein the ultrasonic device is configured to provide the ultrasonic guidance; a monitoring device arranged in the carriage, wherein the monitoring device is configured to monitor vital signs of patients during the operation procedure; an anesthesia device arranged in the carriage, wherein the anesthesia device is configured to maintain an anesthesia state of the patient during the operation procedure; and a fixing device arranged on an inner wall of the carriage, wherein the fixing device is configured to fix the ultrasonic device, the monitoring device and the anesthesia device with the inner wall of the carriage during a driving process of the vehicle body.

A reconfigurable apparatus used to store removable vehicular doors, roofs, roof components and hitch accessories. A rolling frame supports pivoting door storage arms, removable roof storage framework components and tubes for storage of hitch accessories. Components can be reconfigured to allow for compact storage and/or vehicular transportation of the apparatus itself.

A winch assembly for moving a first fifth wheel outwardly from a first trailer and engaging a king pin on a second trailer. The winch assembly includes a pair of parallel, spaced apart rails mounted on the underside of the first trailer. A slide out frame is mounted between the rails and attached to a front axle and a real axle, with wheels. The slide out frame includes the first fifth wheel adapted for engaging the king pin on the front of a second trailer. The first fifth wheel is attached to a pair of first cables on winch drums, driven by winch motors. The winch motors are used for rotating cable drums for retracting the first fifth wheel along a length of the trailer. Also, a pair of second cables on winch drums, driven by winch motors, are attached to the slide out frame. The second cables are used to extend the first fifth wheel outwardly from the rear of the first trailer for engaging the fifth wheel to the second trailer.

A trailer having a framework configured for selectively switching between a wheel-based towing mechanism and a ski-based towing mechanism and wherein the trailer framework is lightweight and configured for supporting an enclosed trailer that may be constructed of lightweight composite paneling. The trailer framework can also be used with a pivotable and removable tow-bar where the tow-bar is configured with a plurality of pivotable attachment points for pivotably securing to the framework. The tow-bar is also connectable to any tow-vehicle and can be removed from the tow-vehicle and the trailer framework when not in use, or can be pivoted upwardly about the trailer framework for storage.
