Disclosed is a display stand including a first rotational coupling unit, and the first rotational coupling unit includes a coupling member installed in a central part of a first link and configured to pass through the first link and a second link so as to allow the first link and the second link to be rotatable in leftward and rightward directions, metal bushes installed on an outer surface of the coupling member so as to surround the coupling member and inserted into the first link so as to press the first link, and first toothed lock washers installed on the outer surface of the coupling member so as to surround the coupling member, disposed on outer surfaces of the metal bushes, and configured to have connection members provided towards an inner surface of the first link so as to be pressed against an inner surface of the second link.

A stand for a laser projection device is provided. The stand includes a mounting structure that couples to the laser projection device. In one embodiment the stand includes three legs that are coupled together at a junction, and a central column extends downward from the junction and the mounting structure is coupled to the mounting structure, thereby permitting the laser projection device to emit light towards a ground.

A telescoping monitor mount includes a center post, a slidable bracket over the center post, a first telescoping arm connected to the slidable bracket, a second telescoping arm connected to the slidable bracket, a first monitor mounting bracket connected to an end of the first telescoping arm opposite the slidable bracket, and a second monitor mounting bracket connected to an end of the second telescoping arm opposite the slidable bracket.

A motorized bracket is intended to receive, in a support, a video projector and having a base, a first arm and a second arm. The first arm is connected to the base at a first motorized rotation axis. The second arm is connected to the first arm at a second motorized rotation axis and the second arm is connected to the support at a third motorized rotation axis. The motorized rotation axes each consist of a motor coupled to a geared motor assembly in direct engagement with the arm or the support that is to be controlled.

A camera lifting structure includes a rail bracket, two fixing portions, two elastic elements, two sliding portions, two connecting rods and a camera module. The rail bracket extends along a first direction. The fixing portions are disposed on two ends of the rail bracket. The elastic elements locate between the fixing portions. Each elastic element has a first end and a second end. Each first end connects with the corresponding fixing portion. The sliding portions respectively connect with the corresponding second end and are configured to slide along the first direction relative to the rail bracket. Each connecting rod has a third end and a fourth end. Each third end is pivotally connected with the corresponding sliding portion. The camera module pivotally connects with the fourth ends and is configured to move relative to the rail bracket along a second direction perpendicular to the first direction.

Apparatus for use with an electronic communication device having a camera to take a selfie picture or video comprising a hand mirror comprising a housing and a mirror surface engaged with the housing. The apparatus further comprises a fastener adapted to engage directly to the mirror surface and the electronic communication device to position the camera in front of the mirror surface. The apparatus further comprises a light source. The apparatus further comprises a control circuit. The apparatus further comprises an input device connected with the control circuit. The input device comprising a first button to activate the camera and a second button to activate the light source.

An apparatus for positioning an electronic display can be combined with an existing work surface to provide a multi-position workstation. In some cases, the apparatus includes a mounting portion configured to support an electronic display and a keyboard. The mounting portion may be movable with respect to the work surface between multiple positions, including for example, a sitting position and a standing position.

The invention is directed to a base for pieces of furniture having at least one supporting column structure. The base comprises a central hub receiving the lower end of a column and a number of arms radiating from the hub. The object of the invention is to provide a furniture base which allows varying its height. This is accomplished by changing the angle between hub and arms, or by shifting the points of attachment of the arms on the hub in the vertical direction.

Provided is a stand capable of supporting an electronic device and improving the degree of freedom in appearance of the electronic device. A stand (1) is a stand for supporting an electronic device (90) having a lower exterior panel (92B) with a curved lower surface. The stand (1) has a stand main body (B) that is located, in plan view, inside an outer circumferential edge of the lower exterior panel (92B) and that has supporting surfaces (11a and 11b) to make contact with the lower surface. Also, the stand (1) has an arm (27) that extends from the stand main body (B) toward the outer circumferential edge of the lower exterior panel (92B) of the electronic device (90) and that has engagement sections (27A and 27B) to engage with an exterior member of the electronic device (90).
