A hook comprising a body having a first coil on a first end and a second coil on a second end. The coils may be spirals curving in opposite directions. The body may be constructed of filament, such as metal wire, and may be hypoallergenic. The coils may be disposed on opposite ends of the body. An aperture may be disposed on the lower side of the body, and may be defined by a loop. A base may interface with the aperture, the interfacing base configured to interface on one side with the body and interface with a jewelry on the opposite side.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.

A band configured to couple a device to a body of a user is disclosed. The band includes a first link comprising a recess defined in a body of the first link, a leaf spring positioned in the recess and comprising a tongue portion protruding from the leaf spring, and a second link coupled to the first link and comprising first and second lip portions extending away from a body of the second link and separated from one another by a gap. The tongue portion is positioned in the gap between the first and second lip portions, and the first and second lip portions engage the leaf spring to retain the second link to the first link.

An accessory attachment system that embodies devices and a method for converting clasp-style fasteners to push-pull detachable fasteners, thereby facilitating attachment of accessories having clasp-style fasteners or any accessory having opposing ends so that they are “ready-to-wear”.

Systems and methods for dynamically adjusting the fit of a wearable electronic device are disclosed. In many embodiments, a tensioner associated with a wearable electronic device can control one or more actuators that are mechanically coupled to either the housing or to a band attached to the wearable electronic device. In one example, in response to a signal to increase the tightness of the band, the tensioner can cause the actuator(s) to increase the tension within the band.

The present invention relates to a buckle type jewelry lock catch, comprising a lock catch body, a buckle sleeve and a buckle, wherein one end of the buckle sleeve is provided with a buckle sleeve matching surface, the other end of the buckle sleeve is provided with a buckle inlet, and an internal wall of the buckle sleeve is provided with lock pins; an external surface of the buckle is provided with U-shaped clamping grooves, a spring chamber is provided inside the buckle, and a spring is provided in the spring chamber; and a thimble of the spring is provided at one end of the buckle, and a connecting mechanism of a jewelry chain is provided at the other end of the buckle. The present invention effectively combines firmness with beautiful appearance, and obtains unexpected technical effects, i.e. firmer and safer, thereby expanding the application range and being more suitable to be used in combination with precious jewelry. The style is fashionable, and the service life is long, which are taken as double insurance. Meanwhile, the present invention has decorativeness and artistry, thereby improving the competitive advantage of the product.

A hook formed into a body formed into a hook shape and having a neck and fabricated from nonferromagnetic material with the body having a first end and a second end. The neck is proximate the first end. One side of the neck includes a center ridge with a flat top surface with either a magnet or ferromagnetic material embedded in the center ridge. The hook also includes a closure having a first closure end and a second closure end and a channel with a floor flanked by two lateral sides. A second magnet or a ferromagnetic material is embedded into the floor opposed to the first magnet or ferromagnetic material. The closure being pivotally and/or pivotally and slidably attached to the hook body by at least one pin. The magnet(s) and/or ferromagnetic material hold the closure in a closed position enclosing a defined space.

The bracelet has more than one main platform fixed on one another so as to form a ring, more than one main assembly item enabling affixation of each main platform onto one another and a decorative part installed on each main platform in a removable manner without disturbing the ring-shaped form of the bracelet.

A clasp includes a male clasp portion having a tongue having an opening, and a female clasp portion having a generally hollow body. The hollow body has a first opening and a second opening. A movable button is disposed in the body, and the button has a first portion positioned in the second opening of the hollow body and a second portion defining a post. A biasing member is operable to bias the button in a locking position in which the post is disposable across at least a portion of the opening in the tongue when the tongue is disposed in the first opening of the hollow body, and the button is operable to being moved to a release position in which the post is disengagable from the opening in the tongue to allow the tongue to be spaced from the hollow body.
