A counterweight arm mechanism having an adjustable dragline tension system capable of adjusting tension; the system comprising a dragline, an extension spring, and a dragline adjustment mechanism; the dragline adjustment mechanism adjusted the overall length of the dragline as a function of the rotation angle of a counterweight arm; the dragline length adjustment mechanism being implemented according to the two legs of a right-angled ΔABC and the property of a+b=2√2R sin(A+π/4); when the counterweight arm rotates, the mechanical structure can be used to drive the vertex of the right angle of the right-angled ΔABC to rotate along with the counterweight arm, and synchronously move in line with the circumcircle of the right-angled ΔABC, thus the tension on the counterweight arm from the adjustable dragline tension system changes with the rotation angle of the counterweight arm.

A TV wall mounting device includes a wall mount box with vertical supports, a display mount receiving a TV, and an extending/contracting portion between the box and the display mount. The extending/contracting portion has lower and upper arms rotatably attached to the wall mount with rear axles, a pair of linear actuators rotatably attached to the wall mount, a front portion that rises and lowers with action of the actuators, and a horizontally-swiveling portion that is raised and lowered with the front portion and is capable of rotating right-left with respect to the front portion. The display mount is attached to the horizontally-swiveling portion. Parallel operation of the linear actuators, wherein each actuator extends and retracts while keeping the same length as the other actuator, causes the display mount to go up and down. Differential operation of the actuators causes the display mount to rotate right and left.

A holding clip apparatus is provided for attaching a mobile electronic device to a tray table of a commercial vehicle, such as a train or airliner. A tray table attachment section of the holding clip apparatus includes an upper support member and a lower support member each extending outwardly in a horizontal direction from a rear support wall. A mobile device holding section of the holding clip apparatus includes a front support wall and a rear support wall extending upwardly from a base portion having a bottom surface. Attachment portions may be provided connecting the tray table attachment section and the mobile device holding section. A mobile device angle adjustment section may be provided that allows the mobile device holding section to rotate to adjust the viewing angle of a mobile device held thereto.

A lift system including a bracket configured to support an object, a support having a first end and a second end, the first end being movably engaged to the bracket, at least one cam engaged to the second end of the support, and a base including a cam follower configured to engage the at least one cam, and at least one bias element having a first end and a second end, the first end engaged to the cam follower.

A friction hinge is described. In at least some implementations, the described friction hinge enables a support component to be adjustably attached to an apparatus, such as a computing device. According to various implementations, a friction hinge includes different friction stages where movement of the hinge is based on different activity mechanisms.

The present invention is a small universal smart phone stand that can fit on a key chain. It can stand a smart phone to custom viewing angles. It transforms from flat into a custom smart phone stand, by just bending two flaps. When the flaps are bent, it creates a gap in-between them. This is where a smart phone is held. One flap is the front support, the other is the back support. The angle of which the flaps are bent into, adjusts the angle of the smart phone. The present invention is made of a shape retaining material. That allows the flaps to retain the shape they are bent into.

A support assembly for supporting a camera relative to a camera support includes an elongate support arm, a first bracket assembly for mounting the camera to the support arm and a second bracket assembly for mounting the support arm to the camera support. Each bracket assembly includes i) a clamp member for clamping onto the support arm, ii) a support member pivotal coupled by a pivot shaft on the clamping member, iii) a mounting member supporting the camera equipment relative to the support member; and iv) a locking member adapted to be coupled between the clamping member and the support member so as to simultaneously fix the mounting member relative to the clamping member at a selected angular position and fix the clamping member relative to the support arm at a selected longitudinal position.

A display mounting system including a central upright support, a first support arm connecting a first terminal upright support to the central upright support, a second support arm connecting a second terminal upright support to the central upright support, and a mounting bracket. The mounting bracket is connected to one of the support arms and is configured to receive an electronic display. At least one of the support arms is rotatably connected to the central upright support such that the support arms can be selectively rotated between an open position and a collapsed position. In embodiments, the support arms are configured to disconnect from the central upright support and the terminal upright supports such that the central upright support and a support arm can be removed, or additional central upright supports and support arms can be incorporated.

An apparatus for viewing augmented reality images in a hands-free manner includes a tracker base in which various interchangeable trackers may be placed. The interchangeable trackers include an image specialized to an application framework running on a device with an image capture device in range of the image. An arm connects to and extends from the tracker base, and includes a clasp for holding the device. With the augmented reality application running, the device provides a display of the augmented reality images associated with the image on the interchangeable tracker in a hands-free manner. The tracker base spins, providing different viewpoints of the augmented reality images. The tracking element and the image capture device are held in a fixed spatial relationship with respect to one another, resulting in a stable image. The apparatus provides interactions in a multi-system environment by invoking commands between the device and an external multimedia component.

An elevatable supporting device for bearing a display is provided. The elevatable supporting device comprises an upright, an energy storage element, and a bearing module. The upright includes a first surface and a second surface which is non-parallel to the first surface. The energy storage element abuts against the first surface and the second surface and includes a first arm providing a first resistance and a second arm providing a second resistance. A first included angle is defined between the first arm and the second arm. When the energy storage element moves from the highest position to the lowest position, the first included angle decreases so that one of the first resistance and the second resistance may increase in order to maintain a total effective resistance along the first axis. Accordingly, the display may be able to stop at any position between the highest position and the lowest position.
