The description relates to hinged devices, such as hinged computing devices. One example can include an expandable hinge assembly that rotatably secures a first portion and a second portion. The example can also include a hinge assembly positioned between the first portion housing and the second portion housing and that includes first and second rotatable links that are rotatable relative to both the hinge assembly and the first and second portions.

A hinge device includes a first connecting member and a second connecting member pivotably connected to the first connecting member by an axle. A rotary member and a limiting member are mounted in the axle. The rotary member includes a at least one positioning groove. The limiting member includes at least one positioning leg. The rotary member is actuatable by the first connecting member to pivot about the axle. The limiting member is fixed on the axle. The limiting member is located between the rotary member and a retaining device biasing the limiting member toward the rotary member. When the first connecting member pivots through an angle relative to the second connecting member, the at least one positioning leg engages with the at least one positioning groove, thereby positioning the first connecting member relative to the second connecting member.

A door hinge includes first and second leaves each with a plate portion, a free edge and an opposite geared edge, the geared edges meshing with each other as the leaves operationally pivot. Each leaf has a front surface and an opposite back surface. A cap covers the meshed geared edges on the back surface and defines a pivot axis for each of the leaves, the cap defining a channel A recess is provided in the front surface of each leaf, the recesses being in communication with the channel, each recess defining a break in the geared edges. First and second access panels are removably secured in the recesses, having a geared panel edge complementary with the leaf geared edge and filling the break, and at least one of the access panels being secured to the respective hinge leaf by security fasteners extending only into the leaf.

A food shield for use in a restaurant or food service institution includes a pair of partially overlapping upper and lower transparent panels, first and second locking assemblies connected to and supporting one lateral side of each of the upper and lower transparent panels, and first and second non-locking assemblies connected to and supporting the opposite lateral side of each of the upper and lower transparent panels. Each of the first locking and non-locking assemblies, which supports the upper transparent panel, is mountable to a respective vertical support post. The food shield is transformable into three different settings. In a cafeteria setting, the upper and lower transparent panels overlap each other to provide a full length barrier in front of food product being displayed. In a self-serve setting, the lower transparent panel is pivoted inwardly such that it resides behind the upper transparent panel. In a self-serve and display setting, the lower transparent panel is adjusted to a horizontal position to create a shelf situated behind the upper transparent panel.

The present disclosure discloses a variable torsion spring damping rotating shaft. The shaft includes a movable unit, a fixed unit, a first connection mechanism, a second connection mechanism, and a torsion spring; the fixed unit is detachable in inserting connection with the movable unit; the first connection mechanism is arranged inside the fixed unit, and the first connection mechanism is connected to an end of the fixed unit; the torsion spring is sleeved on the first connection mechanism, an end of the torsion spring is in inserting connection with the fixed unit, and another end of the torsion is in inserting connection with the movable unit; the second connection mechanism is arranged in the movable unit and is in cooperation with the first connection mechanism; and the second connection mechanism is configured to rotate on the first connection mechanism, to drive the movable unit to move towards the fixed unit.

An electronic device includes a flexible display, a foldable housing, and a flexible display disposed on one surface of the housing. The housing includes a first part, a second part, and a connection unit for connecting the second part to the first part to be relatively movable. The connection unit has hinge members extended substantially in parallel to an edge of the first or second part, arranged between the first part and the second part, and forming part of the one surface of the housing. As the hinge members move relative to each other, the hinge members connect the second part to the first part to enable relative movement of the second part with respect to the first part between a position in which the second part faces the first part and a position in which the second part is leveled next to the first part.

A hinge structure includes a pivot bracket, a first shaft, a second shaft, and a cable. The first shaft is pivoted to the pivot bracket and has a first through hole. The second shaft is pivoted to the pivot bracket and has a second through hole. The cable includes a first penetrating segment, a second penetrating segment, and a curved segment. The first penetrating segment penetrates through the first through hole, the second penetrating segment penetrates through the second through hole, and two ends of the curved segment are respectively connected to the first penetrating segment and the second penetrating segment. In addition, an electronic device including the hinge structure and an assembling method of the hinge structure are also provided.

Provided is a torque hinge which can be easily assembled. A torque hinge includes a restricting member 3 having a hole 31, a shaft 4 passed through the hole 31 of the restricting member 3, a friction member 6 engaged with the shaft 4 in an interference fitting state so as to generate torque due to friction to the shaft 4 which relatively rotates and fitted in the hole 31 of the restricting member 6, and a fixing shaft 41 for unrotatably fixing the friction member 6 to the restricting member 3, the fixing shaft 41 intervening between the friction member 6 and the restricting member 3. The fixing shaft 41 presses a wedge-shaped rotation locking portion 44 of the friction member 6 onto an inner surface of the hole 31 of the restricting member 3.
