A case for an electronic device. The case includes a lower housing having a cavity to receive the electronic device, and an electrical connector configured to couple to the electronic device. A lid is attached to the lower housing with a pivotable joint allowing the lid to rotate between a closed position where the lid is aligned over the cavity and an open position where the lid is angularly displaced allowing the electronic device to be removed from the cavity. The case also includes a hinge that provides the pivotable joint. The hinge is configured such that, when the lid is in the closed position, it is biased to remain closed via a detent, and, such that the lid has one or more stable positions between the fully open and fully closed positions.

A bag with an interior space and an opening includes an opening mechanism comprising a frame structure in communication with the opening, a biasing mechanism adapted to apply a biasing force to the frame structure to move the frame structure from a closed position to an open position, and a latching mechanism adapted to latch the frame structure in the closed position when engaged and to allow the frame structure to move by the biasing force to the open position when disengaged. Movement of the frame structure from the closed position to the open position causes the bag to open to allow access to the interior space. In one version. the frame structure comprises a front frame member pivotally connected to a rear frame member and wherein the biasing mechanism comprises a torsional spring that biases the front frame member to rotate away from the rear frame member.

A luggage case capable of being opened forwards, including a case body; a front panel is provided on the case body; a panel fixing frame is on a side of the front panel facing an inner cavity of the case body; a snap-fitting structure is provided between the front panel and the panel fixing frame: a bottom part of the panel fixing frame is provided with a panel-opening structure, which includes a hinge assembly: bearings and springs are provided in the hinge assembly: two ends of the hinge assembly are fixed to the panel fixing frame and the case body respectively; an opening-closing structure is provided between a top part of the front panel and the case body; when the opening-closing structure is opened, the bearings drive the hinge assembly to rotate forwards to push open the front panel under resilient force of the springs.

A protective and/or ornamental case for a foldable handheld electronic device. The case includes a front shell and a back shell pivotally connected to a hinge cover by one or more coupling mechanisms. A first portion of an electronic device is inserted into the front shell and a second portion of the electronic device is inserted into the back shell. The coupling mechanisms retain the front and back shells operatively engaged with the hinge cover as the electronic device housed in the case is pivotally or hingedly opened and closed, help prevent unintended opening or closing of the device, and keep the device open or closed when so positioned by a user.

An inductive charging case in accordance with certain embodiments presented herein comprises a base and a lid mechanically coupled together via a hinge mechanism. When the inductive charging case is in a closed arrangement (e.g., the lid is positioned adjacent to the base), the lid and base collectively define an interior volume that is configured to enclose an electronic device therein. The electronic device includes one or more rechargeable batteries, a receiver coil, and circuitry for recharging the one or more rechargeable batteries, while the inductive charging case includes inductive charging circuitry, including at least one inductive charging coil, that is configured to provide power to the electronic device which is then used to charge the one or more rechargeable batteries and/or power the electronic device.

A jewelry box includes a lower box component; a diamond supported on the lower box component and having a blue fluorescence; an upper box component hinged to the lower box component for swinging between an opened position and a closed position, the upper box component being coupled to the lower box component at the closed position for covering the diamond, the upper box component exposing the diamond at the opened position; and a light source supported on the lower part or the upper part, the light source emitting an ultraviolet radiation toward the diamond when the upper box component is moved from the closed position. This provides a jewelry box causing a most dramatic impression within an observer of the jewelry box.

A protective and/or ornamental case for a foldable handheld electronic device. The case includes a front shell and a back shell pivotally connected to a hinge cover by one or more coupling mechanisms. A first portion of an electronic device is inserted into the front shell and a second portion of the electronic device is inserted into the back shell. The coupling mechanisms retain the front and back shells operatively engaged with the hinge cover as the electronic device housed in the case is pivotally or hingedly opened and closed, help prevent unintended opening or closing of the device, and keep the device open or closed when so positioned by a user.

A multi-link hinge is proposed. The multi-link hinge is configured to facilitate closing and opening of a door, is capable of sufficiently securing a maximum opening angle of the door while decreasing a gap between the door and a main body, and is also capable of providing convenience to a user when the user opens and closes the door.

An automatically opening box comprising a rectangular base formed from two rectangular panels joined by a foldable spine. A pair of opposed sides extend upwardly from the base at base corners perpendicular to the spine, each having a vertical fold aligned with the spine. A pair of opposed sides extend upwardly from edges of the base at base corners parallel to the spine. Adjacent sides are connected at side corners. At least two side corners include sprung hinges. Both sides of one of the pairs of opposed sides having diagonal folds. The box has a collapsed configuration where both pairs of opposed sides are folded down to be parallel to the base, the base is folded along the spine and vertical folds, and a fastener secures the box in the collapsed configuration, and a deployed configuration where the fastener is released and the sprung hinges deploy the sides and base.

A hinge assembly comprises a first connecting member, a second connecting member, a first shaft, a second shaft, and a clockwork spring. The first connecting member includes a first pivot portion. The second connecting member includes a second pivot portion. The first shaft is pivotally connected to the first pivotal portion of the first connecting member and the second pivotal portion of the second connecting member. The second shaft is configured on the first connecting member and spaced from the first shaft. The clockwork spring includes a first end and a second end away from the first end; the first end fixed to the second shaft rod, the second end fixed to the second connecting member. When the second connecting member pivots with respect to the first connecting member, the arrangement of the clockwork spring can provide a more stable pivoting force for the second connecting member.
