Disclosed is a hinge module including a hinge structure having a first sub-hinge structure including a first center bracket and a first hinge bracket that rotates through a specified angle in a first direction and a second sub-hinge structure including a second center bracket and a second hinge bracket that rotates through a specified angle in an opposite direction to the first direction. The first hinge bracket and the second hinge bracket are separated from each other and are disposed between the first center bracket and the second center bracket, and hinge motion of the first sub-hinge structure is performed independently of hinge motion of the second sub-hinge structure. The hinge module and a foldable display device including the hinge module suppress a phenomenon in which the hinge module is opened when the housing structures are twisted, thereby preventing damage to the foldable display device.

A plate folding and unfolding device and a solar panel structure are provided. The plate folding and unfolding device includes a cam fixed with first plate piece, and a rotating shaft is disposed inside the cam in an axial direction of the cam; a connecting rod, where the connecting rod includes a first end and a second end that are opposite to each other, the first end is connected vertically to the rotating shaft, and the second end is fixed to a second plate piece; a positioning shaft, where the positioning shaft is disposed, on the connecting rod; and an elastic piece, where the elastic piece is disposed on the connecting rod, one end of the elastic piece is connected to the positioning shaft, where a groove that accommodates the positioning shaft is disposed at at least one location of the outer peripheral surface of the cam.

A child play yard includes a frame that includes legs, lower cross bars having first ends pivotally coupled to lower ends of the legs, and a hub pivotally coupled to second ends of the lower cross bars, the hub including a hub mechanical central tube, a column slidably disposed within the hub mechanical central tube, a hub mechanical spindle disposed within the column, and hub lock fingers pivotally coupled to a lower portion of the column and including lower feet portions, the hub mechanical spindle having an enlarged diameter lower end portion that engages lower inner sidewalls of the hub lock fingers and maintains the lower feet portions of the hub lock fingers outside a perimeter of a lower opening of the hub mechanical central tube when the hub is disposed in a lowermost position in the frame.

A screen door for a cooling package of a vehicle that includes proximal and distal frame posts, screen surface, torsion bar, stationary support, torsion bracket and fastener. The proximal frame post is hingedly coupled to the cooling package, and the distal frame post can be hingedly coupled to a secondary door. Proximal end of torsion bar is fixedly attached to proximal frame post, and distal end is moveable relative to the distal frame post. Stationary support is fixedly attached to distal frame post. Torsion bracket is fixedly attached to distal end of torsion bar, and is moveable relative to stationary support. Fastener maintains torsion bracket in a desired position relative to stationary support. Movement of torsion bracket relative to stationary support applies an adjustable torsion on torsion bar, and fastener maintains the adjustable torsion. An adjustment member can be attached to fastener between torsion bracket and stationary support.

Storage units include a housing defining a cavity and opening. A cover covers the opening. The units include a hinge that pivotally couples the cover and housing. The hinge includes a housing mount coupled with the housing. The housing mount has upper and lower portions and a longitudinal member that couples the lower and upper portions, which are spaced apart along the longitudinal member. The hinge includes a cover mount coupled with the cover. The cover mount has upper and lower portions and a longitudinal member that couples the lower and upper portions, which are spaced apart along the longitudinal member. The hinge includes a pivoting member that is coupled with the housing mount at a first pivot point and with the cover mount at a second pivot point. Longitudinal axes of the first pivot point and the second pivot point are offset and parallel to one another.

A hinge device for supporting an electronic device includes a first portion and a second portion movable relative to the first portion with a biasing element supported by one or the first portion or the second portion. The first portion has an arcuate groove, and the second portion has an arcuate rail configured to complementarily mate with the arcuate groove and slide therein. The biasing element contacts a leading edge of the other of the first portion or second portion, and the first portion and second portion are bistable in a closed state relative to one another and an open state relative to one another based at least partially on a surface profile of the biasing element applying a radial force to the leading edge.

The present disclosure relates to an ambidextrous hinge. The ambidextrous hinge includes a first knuckle with a first engagement feature, a second knuckle with a second engagement feature, and a third knuckle movably coupled between the first knuckle and the second knuckle. The third knuckle includes a third engagement feature that engages the first engagement feature to cause the ambidextrous hinge to lock in a first open position when used as a first swing hinge. The third knuckle includes a fourth engagement feature that engages the second engagement feature to cause the ambidextrous hinge to lock in a second open position when used as a second swing hinge.

The current invention relates to the field of hinges, more specifically locking hinges. It is often desirable to automatically secure a door at a position, for example while loading or unloading a vehicle, but most hinges on the market are unable to secure the door automatically. The current invention solves this problem by incorporating a securing means within the barrel of the hinge itself that is capable of releasably securing an attached door along the axis of rotation. The principal use of the preferred embodiment is on a travel trailer, the hinge serving to secure an entry door while loading or unloading the trailer.

There is disclosed in one example, an encasement for a mobile computer, including: an external casing in a clamshell form factor, the external casing including a base, a secondary display chassis hingedly connected to the base at a secondary hinge, and a primary display chassis hingedly connected to the secondary display chassis at a primary hinge disposed at a removed edge of the secondary display chassis from the secondary hinge, the primary display chassis to substantially overlay the secondary display chassis and the base when the primary hinge is in a closed position; and pivot means disposed to substantially bias the secondary hinge against movement from a selected position in at least one direction in the absence of an electrical input.
