A lifting device is provided. The lifting device includes a stationary member, a lifting member, positioning bases, reels, and springs. The lifting member is slidably coupled to the stationary member. The lifting member is fixed to a back portion of the display. The positioning bases are disposed on the stationary member and the lifting member. The reels are pivoted on the positioning bases. The springs are wound around the reels and connected to the other of the stationary member and the lifting member relative to the positioning bases. When the display or the lifting member is subjected to an applied force toward a sliding direction, the lifting member slides toward the sliding direction relative to the stationary member. The springs stretched by the lifting member generate an elastic force, so that the lifting member and the display no longer subjected to a force stay at a height position after sliding.

The invention relates to a rail system for a camera comprising at least one guide rail on which a camera slider is movably mounted, wherein a support structure consisting of multiple hingedly interconnected segments is provided along the at least one guide rail and said segments are in contact with said at least one guide rail.

A spring balanced support device having at least one arm, connected to its surroundings via a movable pivot point, forming an arm mechanism to which a mass may be coupled directly or indirectly at a mass coupling point, balanced by at least one spring, at one end directly or indirectly connected to the arm mechanism at a spring connection point, the other end directly or indirectly connected to the surroundings at a spring base point, wherein the spring base point is located substantially on an axis which extends through the movable pivot point and substantially parallel to a direction of a force exerted on the spring balanced support device at the mass coupling point due to the force of gravity on the mass, or wherein the spring base point is located at a distance from said axis along a line which intersects the axis and which extends substantially parallel to a pivot point axis of the movable pivot point, wherein the movable pivot point is movable along the axis in order to adjust the spring balanced support device.

A displaying unit includes a rail unit, a connecting unit and a display unit. The rail unit includes a rail that extends in a lengthwise direction, a fixed circuit board that is disposed in the rail and that extends in the lengthwise direction, and a fixed electrode set that is disposed fixedly on the fixed circuit board and that extends in the lengthwise direction. The connecting unit is slidable on the rail in the lengthwise direction and includes a movable electrode set that is in sliding contact with the fixed electrode set. The display unit is connected to the connecting unit and is electrically connected to the movable electrode set.

Adjustable, modular systems for suspending objects from multiple points distributed along a span include a track and a plurality of hangers that can be coupled to the track, loaded with an object, and driven along the track, the coupling, loading and driving all accomplished from a limited portion of the full span.

This disclosure describes a modular bridging structure and a system for using that structure. The bridging structure has a channel configured to receive a portion of an elongate rail, the channel being configured to receive the elongate rail substantially perpendicularly to a longitudinal axis of the modular bridging structure, and a rail fastener securing the received rail within the channel. Additionally, the modular bridging structure has a leg receiver configured to receive an elongate leg section such that the leg section is attached through a bottom side of the modular bridging structure. There is a leg fastener that secures the received leg section to the modular bridging structure such that the securing point of the fastener is adjustable along a plurality of points along each leg section.

A dolly system is disclosed, which overcomes drawbacks related to unwanted noise and jerks of prior art dolly systems. The dolly system comprises wheel assemblies (130) that have independently rotating lateral support wheels (132, 133) in combination with a center wheel (131) that interact with a continuous resilient element (122) when rolling along a rail track, without encountering any gaps or bumps and without producing squeal noise due to so-called wheel-climbing that may occur in curves along the rail track.

A portable support platform system and method for assembling the system are provided. The portable support platform system includes a support platform configured to receive theatrical devices and an orientation member attached to the support platform. The orientation member includes an arcuate surface configured to receive a flexible member. The flexible member is fixably attached to the orientation member at one or more locations along the arcuate surface to permit orientation and movement of the support platform when the flexible members are deployed or retracted.

A system for transmitting data, images, and audio to and from an aerially moved payload, the system having one or more media converters for converting coax signals to fiber signals and at least two wave division multiplexers, one for combining two or more distinct fiber signals into a single fiber signal and one for splitting the two or more combined fiber signals back into two distinct fiber signals. The system also includes at least one line along which one or more of data, images, and audio may be transmitted to and from the aerially moved payload.

A bench with integrated, liftable storage for providing integrated, liftable storage includes a base. The base comprises a lift module that has a frame which is box shaped. A platform and a lifter are positioned in an interior space defined by the frame. The lifter is coupled to the platform, such that the lifter can raise or lower the platform within the interior space. A top is positioned on and coupled to an upper face of the frame. An opening is positioned in the top.
