A display stand has two spaced apart legs connected by a horizontal support bar that is attachable to multiple displays. Carriage assemblies allow the stand to adjust the vertical position of the displays, shuttles and rails allow the stand to adjust the horizontal positions of the displays, and a central joint on the support bar allows the stand to adjust the angle between the displays. The carriage assemblies can convert rotational movement of adjustment handles into vertical movement of the support bar that is synchronized at both legs whether the support bar is in a straight or angled configuration. Wheels on the shuttles can provide smooth, consistent contact with rails in the support bar despite changes in the nominal dimensions of the rails. The display stand provides improved smoothness, rigidity, and comfort for the user to support and use multiple displays on a single stand.

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.

An apparatus having a housing, an arm, a motor, and a camera mount. The housing may be connected to a ceiling of a room. The arm may have (i) a pivot portion connected to the housing and (ii) a portion extending from the pivot portion in a first direction. The motor may be connected to the pivot portion of the arm to move the arm in response to a control signal. The camera mount may be connected to an end of the portion of the arm.

An assembly includes an attachment arm having an axle extending from a first end of the attachment arm. The attachment arm of the detachable wheel assembly further includes a securing portion forming a second end of the attachment arm, the securing portion of the attachment arm including a pin positioned to extend above a first frame member of a gantry truss and to secure the first frame member between the pin and a portion of the attachment arm. The attachment arm also includes a frame support corresponding to a second frame member of the gantry truss such that the frame support supports the second frame member when the assembly is secured to the gantry truss, and the assembly includes a wheel rotatably attached to the axle of the attachment arm.

A track system on which a skater dolly can roll, comprising one or more pairs of rails and one or more rail clamps. Each rail clamp supports one or two pairs of rails. Rails held side-by-side are parallel to each other. Rail clamps can also secure two rails in end-to-end configuration. The distance between rails can be about 5/16 of an inch. The track system can include a skater dolly, the load-bearing wheels of which are angled 20-30 degrees away from vertical to provide clearance past the rail clamps. The skater also has stabilizing wheels that are approximately perpendicular to the load-bearing wheels, and which secure the skater to the rails when the skater is in a non-upright e.g. upside-down orientation. The system can include a motor pulley system that moves the skater along the rails.

A fixing device for a display unit, including a fixing mechanism including at least two guide rods arranged in parallel and a support assembly configured to slidably connect to the at least two guide rods, respectively; and a mounting bracket, configured for mounting the display unit thereon; the support assembly comprises a support bracket and at least two rolling assemblies disposed between the support bracket and the at least two guide rods; the at least two guide rods being respectively provided with a guide rail configured for slidably connecting with the support assembly; and the support bracket comprises a support portion configured for connecting with the mounting bracket and at least two fixing portions respectively straddling on at least two fixing portions of the at least two guide rods, and the at least two rolling assemblies further respectively abut against the at least two fixing portions and the guide rails.

A multi-purpose component system for photography is described. The system includes motors having connection channels arranged to engage with T-shaped engagement portions located on photographic equipment components. Cam members located along the engagement portions act to fix the motors in position relative to the components.

The present application provides an automatic photographing device and a self-service photographing machine, including a camera, a vertical guide rail, a slider adapted to the guide rail and a support plate with one end connected with the slider. The slider is provided with a drive mechanism, the other end of the support plate is provided with a horizontal rotation mechanism, the horizontal rotation mechanism is provided with a pitch rotation mechanism, the pitch rotation mechanism is provided with a bracket, and the camera is connected with the bracket through a turning mechanism. The present application can help people to shoot more professional photos with multiple angles and styles, and the photographed photos are more natural and beautiful, meanwhile, the shooting efficiency is improved, and the different needs of photographers are greatly met.

Provided are a photographing apparatus, and a control method and device applied to the photographing apparatus. The photographing apparatus comprises a housing shell, a lighting unit, a guide rail unit and a control unit, communicatively connected with the lighting unit and the guide rail unit, to adjust the light intensity of an object to be photographed in the photographing apparatus.

A mechanical arm assembly which has two arm members connected by an elbow. The movable connectors at the end of each arm are connected by belts or the like to a locking mechanism at the elbow such that engaging the locking mechanism simultaneously locks both movable connectors as well as the elbow.
