A trailer having two independent longitudinal sections pivotally attached and extending rearward from a front section. Each longitudinal section includes a wheel attached to the section with an independent spindle trailer suspension system. The longitudinal sections are capable of expanding laterally and contracting longitudinally when in a stationary position.

The invention refers to the area of construction of structures for personal public purposes, namely, to prefabricated transported structures for installation in limited spaces and can be used in the construction of rapidly erected mobile spatial structures of various functional purposes, as well as in places where capital construction is prohibited. The invention consists in the mobile modular house containing folding blocks that are house components connected between each other, with all components of the house placed on a wheeled platform, and its walls and windows formed from separate modules of a triangular shape, made of solid material, with the edges around the perimeter of each module equipped with magnetic tapes. The technical result to be attained using the invention claimed is decreased assembly time, decreased labor intensity of the assembly, and increased variability of the finished product.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

Aspects of the disclosure relate to a trailer having a frame suitable for transporting an item, such as an oil drilling pipe. The trailer includes a plurality of stabilizers for supporting the frame over a surface, at least one axle attached to a plurality of wheels. The trailer further includes an axle pin group includes first and second axle pins interconnected to respective hydraulic cylinders. The trailer further includes leaf springs connected to respective sides of the frame and mounted to the axle. Retraction of the axle pins away from the leaf springs enables movement of the frame with respect to the axle due to the weight of the frame, if the stabilizers are retracted. In this configuration, the frame can be raised and lowered with respect to the surface. Methods of use are also disclosed.

A trailer for providing a usable space. The trailer includes a wheeled underframe with a base element which is at least partially open at a top, a roof element with a roof surface and four adjacent side walls, and a connection element which connects the base element to the roof element in a set-up state. The connection element has an upper surface with at least two adjacent, opposite side walls. In a travel state, the roof element surrounds the connection element and the base element from an outside at the top and at least partially at the sides. To provide the set-up state of the trailer, the roof element extends a dimension of the base element by being erected substantially vertically, and the connection element increases a height of the base element by being erected, so as to provide a firmly enclosed usable space in an interior of the trailer.

This utility model integrates into the standard structure of a teardrop mini camper, a folding front door that generates a bathroom module. Usually in these vehicles, a rear door is used for the kitchen space, so the mini camper described herein incorporates a door of similar characteristics in its front part, where the drawbar is placed.

An unmanned aerial vehicle (UAV), and specifically discloses a UAV transport box. The UAV transport box has a mounting frame, a box body, a driving device, and a control system. The box body has a bottom plate and a side plate, the bottom plate is fixedly installed on the mounting frame, the UAV is arranged on the bottom plate, and the side plate can be unfolded through the driving device, so that the side plate and the bottom plate are in the same plane to form an area which is large enough to provide a suitable take-off and landing platform for the UAV, and can realize the automatic opening and closing for the UAV transport box.

A folding trailer having a deck which can be raised and lowered to facilitate mounting and dismounting a vehicle or other item from the deck. The rear axle of the trailer is configured with a pivoting offset axle which enables raising and lowering of the deck relative to the rear support wheels.

A tow dolly cross rail assembly includes a male bar and a pair of female bars arranged in a slidable relationship, forming an arched configuration that creates a positive camber effect at dolly tires at the outer ends of the bars. The male bar comprises an apex that forms an angle that orients upwardly, forming an angle between about 165° to 179°. The center male bar and pair of female bars are arranged in a slidable relationship with each other. The midpoint of the center male bar forms an apex. The inner end of female bars is in a slidable relationship with free ends of center male bar. The female bars telescopically slide along the free ends of center male bar for increasing and decreasing length of cross rail. The arched configuration of the center male bar slopes the female bars to create a positive camber at the dolly tires.
