A rotation mechanism includes a base, a rotation plate, and an elastic element. The base has two base side walls opposite to each other, an accommodation space between the two base side walls, an abutting portion, and two pivot portions opposite to each other. The abutting portion is located at one end of the base side walls, and the pivot portions are respectively located at the other end of the base side walls. The rotation plate is pivotally connected to the base and between the pivot portions. The elastic element has a first pivot section, an elastic bending section, and a second pivot section that are sequentially connected to each other. The first pivot section is pivotally connected to the two base side walls, and the second pivot section is pivotally connected to one side of the rotation plate.

A device for the storage of emergency information or items provided in a water-resistant protective case wherein the case is easily transportable or may be molded or formed into a larger structural component, the protective case including a base and a top hinged to said base to provide water-resistant sealing allowed in an open or closed position. The case base and top having side walls to create a volume within the case to provide storage within the case for items or emergency information.

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.

The present invention relates to a card holder including a card holder body. The card holder body includes a first card clamping plate and a second card clamping plate, and a connecting device is arranged between the first card clamping plate and the second card clamping plate to connect the first card clamping plate and the second card clamping plate; the connecting device causes a relative displacement in a vertical direction between the first card clamping plate and the second card clamping plate to form a freely retractable internal space, thereby accommodating a plurality of cards; and the connecting device includes two connecting members rotationally connected through a shaft, and a first elastic member connected with each connecting member. The first elastic member provides an elastic restoring force for the first card clamping plate and the second card clamping plate to respectively restore to an initial position.

A pill container includes a base with a cavity and a lid movable between a closed position and an open position. The base has an integral spring tab such that when the lid is unlocked from the base, the spring tab pushes against an interior part of the lid to move the lid from the closed position to the open position.

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 thermal bag includes a thermal bag main body and an upper cover. A side shaping board is interlaid between the fabrics around the thermal bag main body. The upper cover includes a pair of half covers. An opening assembly is connected between the two half covers. Atop shaping board is interlaid between the fabrics of each of the half covers. A hinge assembly is connected between the side shaping board and the top shaping board located at the same side of the opening assembly. The hinge assembly drives the half covers to open/close the opening of the thermal bag quickly.

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 one another by one or more springs or other tension 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 tension mechanisms retain the front and back shells operatively engaged with one another 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.

Disclosed is a wallet comprising two shell halves which are associated by a rigid spine to open and close the wallet, and containing a bunch of keys, anchored to the wallet. The wallet is biased to the open position by a pre tensioned skin which covers windows in the two shell halves. The skin allows temporary outward bulging by elasticity, and immediately springs back into the initial unloaded state at the time the bulging load is removed.
