An arm mechanism includes a first arm, which is hollow, a second arm, and a connection portion for mutually rotatably connecting the first arm and the second arm. A connection portion 15 includes a rotary shaft extending in a direction perpendicular to an axial direction of a first arm 11 and a second arm 12, a friction portion for generating a frictional force against rotation of the rotary shaft, and a biasing member which is housed in the first arm, has an end portion facing away from the rotary shaft and connected to the first arm, has an end portion facing the rotary shaft and connected to the second arm via a connection member, and generates a contraction force which is increased with an increase in angle between an axis of the second arm and an axis of the first arm by rotation of the rotary shaft.

An awning is disclosed. The awning comprises a case assembly comprising a housing, configured to be mounted to a dwelling, and a lead rail, a roller assembly mounted in the case assembly and including a roll tube rotatable relative to the case assembly, a lead rail assembly coupled to the lead rail, the lead rail assembly movable relative to the housing between an extended position and a retracted position, a canopy having a leading edge and a trailing edge, the leading edge being connected to the lead rail assembly and the trailing edge being connected to the roll tube, and a spring arm assembly connecting the housing of the case assembly to the lead rail, the spring arms including a first arm and a second arm pivotable relative to one another, the spring arm assembly allowing the lead rail assembly to move between the extended position and the retracted position.

Modular awning systems and related methods are disclosed. The modular awning system has a frame structure 3. The frame structure can be mounted to a roof of a vehicle. The modular awning system has an awning bracket for coupling to the frame structure, the awning bracket being for mounting an awning. The modular awning system has a front fairing and a rear fairing at opposed ends of the frame structure.

A tank trailer includes a tank having an outer surface face and an inner surface and a central longitudinal vertical plane extending between the first end and the second end. The outer surface faces away from the central longitudinal vertical plane and the inner surface faces towards the central longitudinal vertical plane. The outer surface and the inner surface define an interior volume adapted to be filled with material. The tank trailer may further include a set of ground-engaging wheels supporting the tank trailer from below, a bar positioned proximate the outer surface of the tank and a light source provided on the bar. The tank may further include a frame member operatively engaged with the bar and a sheet material extending between the bar and the frame member. The frame member is movable between a first position and a second position.

An awning assembly with a mount portion, an extendable bar assembly, an upper canopy being retractable to a compact configuration adjacent to the mount portion and extendable to an extended position upon extension of the extendable bar assembly to provide shade from above, a lower canopy coupled with the extendable bar assembly and extendable therefrom to provide shade from a side position. The extendable bar assembly comprises a first roller coupled with the upper canopy, a second roller coupled with the lower canopy and a motion generator coupled with the second roller, the motion generator configured to store energy as the second roller is moved to retract the lower canopy and configured to use the stored energy to move the second roller to extend the lower canopy from the extendable bar assembly.

A protection device is provided, including a first fixed member, a second fixed member, a supporting member, a roller, an awning, an electromagnetic device, and a power supply unit. The supporting member connects to the first and second fixed members. The roller is movably disposed on the supporting member. The power supply unit provides electrical power to the electromagnetic device, so that the electromagnetic device attracts the roller, and the awning remains in a received state. When the power supply unit stops providing electrical power to the electromagnetic device, the roller moves along the supporting member, and the awning is expanded to cover the equipment.

The embodiments relate to a self-supporting articulated-arm cassette awning, in particular for motor homes or trailers, comprising articulated arms (20) that are pivotable at awning arm joints or shoulder joints (10), and brackets or shoulders (II) for connecting the entire awning (100) to the vehicle by means of fastening elements and for receiving joint pins (I) in an insertable, in particular, slidable manner and for at least limiting the twistability of joint pins (I) of those parts of the awning arm joint or shoulder joint that are fixed to the vehicle. Desirable is a compact, continuously variable twisting arrangement for the joint pin which, at the same time, is capable of absorbing the high torques of the extended awning. This is achieved in that at least one, in particular, at least one multi-part bracing or clamping means (III, IV) is provided which can be inserted, in particular slid, into at least one of the brackets or shoulders (II) and which acts in particular radially with regard to the brackets or shoulders (II). The bracing or clamping means (III, IV) can be twisted with regard to the associated bracket or shoulder (II) about its longitudinal axis (12), at least to a limited degree, and receives the joint pin (I) in a positive- or nonpositive-locking manner. Alternatively or additionally it is proposed that at least one height adjustment and/or tilt adjustment means and at least one twisting means of the associated joint pin (I), which twisting means is continuously adjustable about its longitudinal axis, are arranged coaxial to each other in the bracket (II).

An awning arm assembly is provided that includes inner and outer arms. A joint is provided that has an axle, e.g., any structure about which rotation can be provided coupled with one of the inner arm and the outer arm and a hollow body disposed about the axle. The hollow-body is coupled with the other of the inner arm and the outer arm. The hollow body is coupled with the axle such that when the outer arm moves relative to the inner arm the angle between the hollow body and the axle (and thereby the inner and outer arms) is adjusted.

An awning arm is provided in which internal components are concealed and in which tension is adjustable. The arm includes an elbow that includes an outer knuckle that includes a top tang and a bottom tang, the tangs rotatably engaged to a circular encasement of an inner knuckle via a plurality of bushings. Two hubs are concealed by the encasement and the tangs, the hubs secured within the two tangs. A webbing is secured within the hubs, a pull upon the webbing urging the rotation of the hubs and consequently the outer knuckle and the elbow as a whole. Arm extrusions are attached to the outer and inner knuckles, with the rotation of the elbow causing the bending and straightening of the arm. Components that prevent the arm from overextending are concealed within the elbow.
