The present disclosure refers to aerial systems for cameras, typically for stabilized cameras, and also called suspended camera systems, which allow to move a camera through a three-dimensional space by means of cables. The present disclosure includes an aerial system for a camera, which comprises a main axle and at least three arm axles, the arm axles being perpendicular to and independently rotatable around said main axle. The arm axles are coupled to arms which in turn couple to a cable which is fed and reeled from a main reel for feeding and reeling a cable, and, upon coupling of a cable to each arm, the cables support a camera head coupled to the said means for coupling. The solution of the present disclosure enables, including through the provision of arm axles which rotate in relation to a main axle and independently from each other, to reach a wider area.

A kit of portable modular components for use in demountably configuring a variety of structural assemblies. The kit comprises three types of elongate structural support components wherein the first type has a pair of opposed male ends, the second type has a male end and an opposed female end, and the third type has a pair of opposed female ends, wherein the male ends are configured for demountable engagement with the female ends. Each of the male ends comprises a cylindrical body with at least one linear set of two spaced-apart prongs around the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels for receiving therein the cylindrical body and the at least one linear set of prongs. The female ends are provided with locking assemblies for releasable engagement the male ends.

Disclosed is a display device. The display device of the present disclosure includes: a rail which extends long; a moving wall which extends long in a direction intersecting the rail and has a display panel; and a rod which is positioned between the rail and the moving wall; wherein one end of the rod is coupled to the rail to be movable in a length direction of the rail, and the other end of the rod is fixed to the moving wall, wherein the moving wall is movable in the length direction of the rail.

A kit of parts for use in demountably configuring a variety of structural assemblies. A kit may comprise a plurality of cylindrical structural components configured for engagement with various types of male connector components along the sides or at the ends of the cylindrical structural components, there provided for demountable engagement of a female-end socket component at the end of another cylindrical structural component. The kit may additionally comprise components for one or more of roller carriage assemblies and/or one or more of sliding carriage assemblies configured for rolling or sliding movement along rail assemblies comprising a plurality of cylindrical, square, rectangular, or octagonal track components. The rail assemblies may be supported by bases comprising the cylindrical structural components and other components such as weight components, as well as threaded foot components or threaded caster components on which the rail assemblies can be adjustably levelled.

A carriage that records data while moving on a rail system including a first moving unit located on one side of the rail and configured to move along the rail, a second moving unit located on a different side of the rail from the first moving unit and configured to move along the rail, a spring unit configured to slide one or more of the moving units in a direction perpendicular to the direction of the rail, and a position maintaining unit located between the first moving unit and the second moving unit, wherein the position maintaining unit prevents the first moving unit or the second moving unit from sliding more than a predetermined distance when traveling along the rail.
