Low-profile computer supports include features to reduce the thickness and improve the portability or storage capability of a computer system while it is disassembled, packaged, shipped, or moved. Some computer systems have a computing device and a dock device that can be stored and moved separately or that can store or support accessories associated with the computer system. Some computer systems have a movable stand configured to transition between a collapsed state and a deployed or standing state. Some stands include handles or grips for moving the computer systems while collapsed. Other computer systems include handles or grips to provide areas to more easily carry the computer systems. The handles or grips can have features such as a flexible material to hide or mask their appearance on the computer system.

The embodiment of the present application provides a balance mechanism and a mounting bracket. Wherein, the balance mechanism includes: a mounting part; a sliding part, which is slidably connected to the mounting part; a spring, the first end of the spring is fixed to the sliding part; an adjuster, which has a third end and a fourth end opposite to the third end, wherein the third end is connected to the mounting part, and the fourth end is connected to the second end of the spring. The adjuster is configured to to adjust the spring, so as to stretch and compress the spring. The embodiments of the present application can reduce the cost of the balance mechanism and thereby reduce the cost of the mounting bracket.

A screen support frame includes a base and a supporting member that includes a supporting member mounting portion, which has one end mounted to the base and an opposite end formed with a protrusion, and a supporting member rotating portion including a receiving hole in which the protrusion of the supporting member mounting portion is received. The supporting member rotating portion includes rails, between which a longitudinally movable member is arranged. A frontward projection arm extends from one side of the longitudinally movable member. A screen fixing portion is mounted to the frontward projection arm of the longitudinally movable member of the supporting member rotating portion and includes symmetrically arranged elastic members and symmetrically arranged friction members. The screen fixing portion further includes a rotating disc. The present invention provides effects of adjusting of angle of rotation, vertical position, elevational angle, and sideway rotating angle.

A mounting assembly includes a mounting block. A first shaft is supported by the mounting block and movable about a first rotational axis and a first extension axis with respect to the mounting block. A second shaft is coupled to the first shaft and movable about a second rotational axis.

A mobile device supporting assembly includes a supporting mechanism having a base plate, a carrier plate to be supported on the base plate, and a lever attached to the base plate and adjustable relative to the base plate, and a mobile electronic facility to be supported on the carrier plate. The carrier plate is adjustable relative to the base plate with the lever for allowing the mobile electronic facility to be adjusted relative to the base plate to any suitable or selected height. The lever includes a spindle engaged with the base plate for pivotally attaching the lever to the base plate, and includes an axle engaged with the carrier plate for pivotally attaching the lever to the carrier plate.

A supporting device is provided and includes: a base; an upright column disposed on the base; a lifting module disposed on the upright column; a constant force arm unit including: a first rotating member rotatably disposed on the upright column and defining a constant first effective force arm; and a first wire wound on the first rotating member; a variable force arm unit including: a second rotating member linked with the first rotating member and defining a variable second effective force arm; and a second wire wound on the second rotating member; and an elastic force module connected to the first wire; where the torques respectively generated in the first wire and the second wire are balanced with each other.

A personal support apparatus includes a frame having an inner surface for supporting a forehead of a user while seated in a forward-leaning position. The frame has a hollow central region to receive the user's face when the user is seated in the forward-leaning position. A pair of cheek support bodies are disposed on the inner surface of the frame. The apparatus also includes a stand having a recess in a first end to receive a portion of the frame such that a position of the frame is adjustable within the recess to set a height of the frame with respect to the user. A chest support is disposed on the stand. A base is attached to the second end of the stand.

A desktop lifting platform includes a lifting column, a desktop, a base, a controller, and a manipulator, wherein the base is placed on a work platform like a desk; the lifting column includes a drive motor; the controller includes a main control unit (MCU) and a motor-driving circuit, the output end of the MCU is connected to the motor-driving circuit; the desktop lifting platform includes a sensing unit adaptable for detecting or sensing whether the desktop lifting platform hits an obstacle or tilts, such that when sensing that the desktop lifting platform hits the obstacle or the tilts, the sensing unit emits a signal to the controller for controlling the lifting column to stop lifting.

The present invention relates to a gaming chair with a rotatable holder, which includes a backrest, a seat, two armrests, a bracket, and a rotatable holder. The rotatable holder further includes: a holder fixing arm, a vertical column, first cantilever, second cantilever and a clamping unit, wherein one end of the holder fixing arm is fixedly connected to the bottom of the seat of the gaming chair, the other end of the holder fixing arm is fixedly connected to the vertical column, and one end of the first cantilever is rotatably connected with the vertical column through the sliding locking shaft, the other end of the first cantilever is rotatably connected with one end of the second cantilever, and the other end of the second cantilever is rotatably connected with the clamping unit through the rotating support, so the clamping unit is used for clamping mobile devices. The armrest further comprises: an armrest fixing arm, first connector, a rotating arm, second connector and an armrest panel.
