An overhead display assembly includes a display monitor coupled to a monitor tray. The monitor tray is positionable in an operational position and a maintenance position. A support stanchion has an anchoring part, a coupling part, and a stanchion body extending from the anchoring part to the coupling part. The anchoring part is coupleable to a fixed vertical or horizontal supporting structure. A counter-balanced hinging mechanism has one or more pivots upon which monitor tray is configured to rotate with respect to said support stanchion. A force producing device is configured to apply a variable amount of force to the monitor tray based upon a position of the display monitor, the variable amount of force being at least a force sufficient to maintain the monitor tray stationary in an intermediate position between the operational position and the maintenance position.

The present disclosure provides a backplane, a frame structure and a display device. The backplane provided in the present disclosure is secured to a middle frame in a display panel to form a frame structure of the display panel, the backplane including: a bottom plate and a skirt connected to edges of the bottom plate, wherein at least part of the skirt is provided with a clamping member for securing the backplane to the middle frame, the clamping member is provided with a dismounting structure for disengaging the clamping member from the skirt under an external force so that the backplane is separated from the middle frame.

A base for supporting an object comprising a plurality of legs, a shaft concentrically located relative to the legs, an anchor attached to the shaft, and an attachment point for receiving an object. The anchor can be inserted into a substrate to maintain the stability of the base.

An installable and dismantlable apparatus as provided by the present invention includes: a load bearing part; a fixing mechanism including an unlocking drive component and a fixing moving component, the unlocking drive component disposed on the load bearing part, and the fixing moving component connected with the unlocking drive component; and a transmission mechanism including a first stage transmission component and a second stage transmission component, the first stage transmission component located on the load bearing part, the second stage transmission component connected with the unlocking drive component, and the first stage transmission component connected with the second stage transmission component. The present invention not only realizes quick installation and dismantling, and improves the efficiency, but also saves manpower and time, and reduces cost.

An installable and dismantlable apparatus provided by the present invention includes: a load bearing part, a toggle assembly rotatably disposed on the load bearing part and a fixing assembly movably disposed on the load bearing part, and the fixing assembly is driven to move for fixing while the toggle assembly rotates. Through the use together of the load bearing part, the toggle assembly and the fixing assembly, while installed, the toggle assembly rotates and the fixing assembly is driven to move, and then the fixing assembly acts on another part for fixing; while dismantled, only the fixing assembly needs to be pushed towards its initial position, which not only ensures the convenience, reliability and firmness during the installation and fixation, but also saves manpower; and in practical use it is easy to operate and convenient for workers to install and dismantle quickly while ensuring the fixing effect.

Security apparatuses, and methods for providing the same, are described herein. In certain embodiments, a security apparatus includes first and second mounting brackets each including a respective support shelf and a respective support arm. One or more brace elements are attached to the support shelf of each of the mounting brackets. Each brace element includes a respective corner element to be placed over a respective one of four corners of a rectangular shaped portable electronic device. A pair of neck portions are securable to one another with the first and second support arms sandwiched therebetween. A collar is configured to be slid over and encase peripheries of the neck portions. One or more bolts or other fastener(s) extending from at least one of the neck portions, or attached thereto, is/are used to secure the security apparatus to a tabletop of a display table or to another display surface.

A locking mechanism for the folding chassis of electric cutting machines. The chassis (1) comprises: a supporting base (11), a tilting arm (12), and an end arm (13) bearing wheels (14) that are collapsible with respect to a principal arm (10) between a folded and an unfolded position of the chassis. The locking mechanism (2) is installed on the tilting arm (12) and comprises: a locking clip (21) capable of being turned manually between an operative position for the locking of the chassis (1) wherein it is coupled with a number of locking rods (112, 113), and an unlocked position of the chassis (1); a manually displaceable trigger for the retaining of the locking clip in the operational position or the free position; and an elastic element that tends to displace the locking clip (21) and the trigger (22) towards the unlocked position of the chassis (1).

The quick mounting structure includes a first connector, a second connector, and a self-locking mechanism; the self-locking mechanism is on the second connector, and the first connector is connected to the second connector through the self-locking mechanism; the self-locking mechanism includes a quick mounting block, a transmission arm, a locking block, a rotating shaft, and a first elastic member; the quick mounting block is connected to the first connector; the second connector is provided with a quick mounting groove, and all of the transmission arm, the locking block, the rotating shaft, and the first elastic member are arranged in the quick mounting groove; the transmission arm is rotationally connected to the second connector through the rotating shaft; the first elastic member is connected to the transmission arm or the locking block for enabling the locking block to be in a locked state in a normal state.

In a method for dust removal in a rollable display device, a control module activates rolling mechanisms and a dust removal mechanism of the rollable display device. The control module determines a first amount of dust particles on a display surface of the rollable display device using data from a dust detection mechanisms. When the first amount of dust particles is determined to exceed a threshold, the control module engages magnetic locks to lock the rolling mechanisms, and the dust removal mechanism continues to remove the dust from the display surface. The control module determines a second amount of dust particles on the display surface. When the second amount of dust particles is determined to fall below the threshold, the control module disengages the magnetic locks to release the rolling mechanisms. Dust removal mechanism may include piezoelectric strips or an ultrasound haptic effect generation module.

An assembly for using a POV camera by means of a mount. The mount generally includes a cotter pin and a spring for further securing the camera to the mount. The mount disclosed herein is comprised of aluminum, versus prior known plastic, and used a quick release spring plunger. Further, a tether loop on the mount acts as a failsafe to prevent camera loss.
