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 invention relates to a board configured as a jewellery board (1; 2; 3) for arranging and storing items of jewellery such as necklaces, decorative bands or rings, comprising a number of cutouts (16) which penetrate through the board (10; 40; 50) with retaining means (26) integrated therein for detachable fastening of the respective items of jewellery to the board, comprising a pin-like projection (26) as retaining means which projects upwards into the cutout in the lower region of each cutout (16), and comprising a spacer (12; 44; 52) of the board (10; 40; 50) for maintaining a free space (A; a) on a rear side (18; 48; 56) of the board (10; 40; 50) at least in the region of the cutouts (16).

Provided is a system and method for authentication of collectable objects. A hi-resolution digital camera in communication with a nonvolatile data storage device having a data partition capable of being made immutable is provided. The nonvolatile data storage device is compatible with a computerized device, and the hi-resolution digital camera is operated to record at least one hi-resolution digital image of at least one unique appearance characteristic of a collectable object at an image resolution of at least 300 pixel dots per inch at 1:1 image scale. The at least one hi-resolution digital image is stored in the data partition of the nonvolatile data storage device, together with additional image data. A tamper-resistant marking associated with the collectable object is placed on the nonvolatile data storage device

Disclosed herein is a jewelry display apparatus comprising a plurality of arms, each arm displaying a different piece of jewelry. The arms are arranged such that they can be closed to provide an attractive display for showing the plurality of jewelry next to each other or spread apart from each other to allow the customer to view the jewelry in isolation. The arms are preferably joined together at a common pivot point about which the arms rotate with respect to each other.

Disclosed is a container suitable for holding objects such as flowers and which may include a body having at least one wall defining a cavity. The at least one wall may include openings separated apart from each other. A tensioner may pass through the openings. A platform may be situated within the cavity and coupled to the tensioner so as to receive a force from the tensioner when a tension is applied to the tensioner. This force may be operative to lift the platform and the flower coupled thereto so that the flower partially or fully extends from the cavity while at least a portion of the platform remains in the cavity.

A jewelry storage and display device for storing and securing jewelry in an organized manner. The device resembles a binder with rings and a vertical spine for receiving any number of internal pages. The internal pages expand outwardly in panels and contain a variety of transparent pockets for the storage of various pieces of jewelry. The panels are separated by a foldable spine providing separation between each panel.

Modular frames for instructional use that provide secure mounts for geometric solids are presented. Some contemplated modular frames can be assembled into three dimensional modular devices and are particularly suitable for instructional purposes. Modular devices comprising two or more frames could be coupled via a clip in two or more different configurations. Containers including conductive material and configured to provide a Faraday cage around their contents are also provided.

A “Visible Storage and Object Retrieval” (ViSOR) system provides a modular system for concurrently organizing, storing, protecting and viewing objects stored within various containers (referred to herein as “windowed storage devices”) having a fully or partially transparent or translucent window that enables a user to view container contents without needing to open that container. These windowed storage devices are further configured to interface with a wide variety of interchangeable storage devices and systems while preventing tangling, knotting, destruction, breakage, interweaving, etc., of objects contained therein. More specifically, each windowed storage device is removably couplable to a plurality of storage modalities, either directly, or via an intermediary connector that itself is configured to be removably coupled to any of the storage modalities. These intermediary connectors enable windowed storage devices to be transferred between a variety of storage modalities. In further implementations, the ViSOR system includes a computer-based monitoring and access system.
