In particular, the elastic means (10) comprise an elastically yielding laminar body (11) shaped in such a way as to substantially embed in its own overall encumbrance the rotation means (9) which include a single idle roller (12; 156) extending for the entire height (H), defined parallel to said main axis (Y), of a head portion (13) of the strike block (2; 201), opposite to the base portion (14) associated with the fixed or bearing auxiliary structure (A).

An adjustable resistance hinge system for a joint connecting at least a first articulating member and a second articulating member, the hinge system comprising a central element defining a hinge axis. The central element comprises a first and a second elongate arm, each elongate arm extending away from the hinge axis, and a first and a second keeping element hinging on the hinge axis are attached to the first and the second articulating members, respectively. A first and a second biasing device are also engageable with the first and the second elongate arms, respectively. The first and the second elongate arms extend into the first and the second articulating members, respectively, and the first and the second biasing devices engage the central element to resist relative motion of the first and the second articulating members about the hinge axis. The adjustable resistance hinge system allows two joined members to be adjusted to replicate desired physiology, limits, and resistance.

An electronic device according to one embodiment may include: a first housing including a first side; a second housing including a second side facing the first side; at least one first magnetic member configured to be rotatably disposed inside the first housing and adjacent to the first side; and at least one second magnetic member configured to be rotatably disposed inside the second housing and adjacent to the second side, wherein the first housing and the second housing are rotatably coupled to each other by a magnetic force between the at least one first magnetic member and the at least one second magnetic member. Various other embodiments are also possible.

Systems and methods are disclosed for preventing a display component of a portable information handling system from opening when in an upside down position. The portable information handling system may include a base component coupled to the display component by a gravity lockout hinge. The gravity lockout hinge may include a shaft, a bearing channel having a bearing channel surface opposite the shaft, and a movable bearing disposed in the bearing channel. The gravity lockout hinge may, when the portable information handling system is in an upside down position and a gravitational force is exerted on the display component, exert a first frictional torque on the shaft that may cause the movable bearing to contact the shaft and the bearing channel surface, and exert a second frictional torque on the shaft that may prevent an angular position of the display component relative to the base component from being changed.

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 cooking device has improved operator interface features, including a counterbalance mechanism operable to retain an upper platen in predetermined open and closed positions, and a non-stick sheet retention feature designed to prevent sagging of a Teflon or other non-stick sheet of material at an upper cooking surface.

A hinge for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, between a closing position and an opening position, the closing element being anchorable to a stationary support structure, such as a wall, a floor, a frame or similar, includes a hinge body anchorable to the stationary support structure or the closing element, and a pivot defining an axis and anchorable to the closing element or the stationary support structure. The pivot and the hinge body are coupled so as to cause the closing element to rotate between the opening and the closing position. The hinge body includes a working chamber defined along the axis to house the pivot.

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 hinge having a first hinge part and a second hinge part. The second hinge part has a hinge pin to which the first hinge part is connected for movement relative to the second hinge part about a hinge axis between a closed position. An over-close mechanism is provided comprising a catch member on the second hinge part arranged to co-operate with the first hinge part to urge the first hinge part towards the closed position during closing movement of the first hinge part and to retain the first hinge part arrange to co-operate with the hinge pin to urge the first hinge part towards the closed position during closing movement. A soft-close mechanism is provided comprising a damper member on the first hinge part arranged to co-operate with the hinge pin to provide a braking force in the direction of closing.
