A luggage includes a pull handle unit, a pressing unit mounted in the pull handle unit, a driving unit connected with the pressing unit, a transmission unit connected with the driving unit, and a wheel unit connected with the transmission unit. The pull handle unit includes an outer pipe and an inner pipe. The wheel unit includes a single wheel. When the inner pipe is moved downward in the outer pipe, the wheel is braked and cannot be moved anymore, and when the inner pipe is moved upward in the outer pipe, the wheel is unlocked and is moved freely. Thus, when the inner pipe is retracted into the outer pipe, the wheel is braked temporarily, such that the luggage is locked and cannot be moved when not in use.

The pull handle unit includes an outer pipe and an inner pipe. The wheel unit includes two wheels and a brake member. When the inner pipe is moved downward in the outer pipe, the two wheels are braked and cannot be moved anymore, and when the inner pipe is moved upward in the outer pipe, the two wheels are unlocked and moved freely. Thus, when the inner pipe is retracted into the outer pipe, the two wheels are braked by the brake member, such that the luggage is locked and cannot be moved when not in use.

It is described herein a table which may comprise a panel (100), a first extendable leg (200), a second extendable leg (300), a first foot (400), a second foot (500), and a control assembly (600). The first extendable leg may be connected at a first end to a bottom surface of the panel adjacent to a first edge of the panel. The second extendable leg may be connected at a first end to the bottom surface of the panel adjacent to a second edge of the panel opposite the first edge of the panel. The first extendable leg may be connected at a second end to a top surface of the first foot. The second extendable leg may be connected at a second end to a top surface of the second foot. The first foot may further comprise a pair of first casters connected to a bottom surface of the first foot. The second foot may further comprise a pair of second casters connected to a bottom surface of the second foot. At least one of the first extendable leg and the second extendable leg may further comprise a linear actuator electrically connected to a battery of the control assembly.

A caster assembly comprises a caster wheel having an outer surface. A wheel support is coupled to the wheel to support the wheel for rotation about a rotational axis and for swiveling about a swivel axis. A brake assembly comprises a brake having a cammed wheel engaging surface shaped to engage the outer surface of the wheel and a brake actuator to move the brake relative to the wheel from an unbraked position to a braked position in which the brake limits rotation of the wheel about the rotational axis. The cammed wheel engaging surface is arranged to articulate relative to the wheel support. The cammed wheel engaging surface articulates relative to the wheel support in response to the wheel rotating about the rotational axis after the brake is initially placed in the braked position such that the cammed wheel engaging surface more deeply engages the wheel with rotation of the wheel about the rotational axis.

A castor structure includes a wheel support unit, an operation unit, a locking member, a directional member, a directional brake member, a bent elastic bar, and two resting members. The operation unit includes a drive shank formed with an annular groove which has an upper tapered face and a lower tapered face. The locking member includes a plurality of locking teeth. The directional brake member includes a plurality of directional toothed grooves. The elastic bar extends through the directional member and the annular groove. Thus, the elastic bar is stretched outward by the annular groove of the drive shank when the drive shank is moved downward, to provide a micro-adjustment effect, such that the directional toothed grooves of the directional brake member align with and exactly engage the locking teeth of the locking member.

Apparatus for covering product containers loaded in a cargo container is disclosed. The apparatus includes an automated cord reel including a spool and a motor configured to drive the spool. The spool when activated reels in a cord attached to a cargo blanket to spread the cargo blanket over product containers in the cargo container in a smooth motion and/or relatively constant speed to prevent snagging on the product containers. The automated cord reel may be configured as a mobile unit with wheels. A brake system may be provided to prevent movement of the automated cord reel during operation. The automated cord reel may have a battery to provide electric power to the motor. A magnetic floor brake may be configured to hold a cart body in a selected position.

A caster system, including a housing portion, which includes first and second side walls defining an operational space therebetween and an upper wall including a central bore. A rolling assembly is disposed in the operational space, and is rotatable relative to the housing. The rolling assembly includes an exterior rim formed of a resilient material having at least one coloring agent embedded therein. A vertical connection assembly includes a shaft adapted to be fixed to a furniture article and to extend through the central bore in the upper wall. The housing portion is rotatable about the shaft of the vertical connection assembly. The coloring agent is adapted to be luminescent or phosphorescent in a dark environment.

The invention relates to a single wheel caster with a support element including a top element and a base element which includes at least one support arm, wherein the base element receives at least one hub for a wheel, wherein a thread protector is arranged on the hub, wherein a fixation device is arranged between the wheel and the support element. It is an object of the invention to provide a novel single wheel caster with substantially reduced assembly complexity. The object is achieved in that the locking device is arranged without additional fastening elements in an interior of the support element between at least one inner surface of the support element and at least on contact surface arranged rotationally fixated at the wheel, wherein the contact surface firmly contacts the locking device when the caster is assembled.

A caster hub structure has an outward facing brake ring with a tooth profile on its outer surface. A brake block with a tooth profile on its outer surface is engageable and disengageable with the brake ring. The brake block material may be harder than the brake ring material, or the brake ring material may be hardness the brake block material, depending upon the application. The brake block tooth profile is configured to slip with the brake ring tooth profile at a first wheel rotational speed when the brake block is engaged with the brake ring, and the brake block tooth profile is configured to interlock with the brake ring tooth profile at a second wheel rotational speed when the brake block is in the engaged with the brake ring, the first speed being higher than the second speed.
