A wrist-worn device clasp that secures a strap of the wrist-worn device. A first mechanical part of the wrist worn device interlocks with a second mechanical part by motion in a first plane in order to resist motion perpendicular to said first plane. The first mechanical part also inhibits a first securing part and a second securing part being separated by tension along the strap substantially perpendicular to the first plane when the first mechanical part and second mechanical part are engaged with each other. The first securing part and the second securing part inhibit separation of the first mechanical part and the second mechanical part by motion parallel to the first plane when they are engaged with each other by motion perpendicular to the first plane.

A locking mechanism fastened at neck, ear and wrist areas with at least one male part body, includes a female part body, wherein the male part body is attached to the female part body. The locking mechanism includes a mounting opening, wherein the male part body is advanced towards a direction and placed in the mounting opening, moving jaws meeting to lock the male part body entering the mounting opening of the female part body, at least one retainer tab formed on the moving jaws, and male part teeth with tooth sockets, wherein the at least one retainer tab is seated on the tooth sockets.

The present application relates to a wearable device, a strap, and an engaging mechanism. The wearable device includes a watch body and a strap. The strap includes a strap body, a peg, a eject pin, and a linkage component. The strap body is provided with a receiving space, and the strap body is provided with a peg-sliding hole and a first through hole. One end of the peg passes through a peg-sliding hole and the other end is located in a receiving space of a watch body; the eject pin is located in the receiving space and can pass through the first through hole; the peg is configured to drive the eject pin to pop out from the first through hole via the linkage component and engage with the installation groove; the peg is further configured to drive the eject pin to move towards the receiving space.

The invention discloses a bracelet assembly corresponding to multi-attribute physical connections, which has a groove link, which has a link base and a groove base. There are a first through hole and a second through hole penetrating in a lateral direction and respectively arranged at the two ends of the link base in a lateral direction, and the first through hole and the second through hole are aligned in the lateral direction to form a first axis. And the link base is provided with a first cylindrical portion and a second cylindrical portion, the first cylindrical portion is provided with a first shaft hole penetrating in a lateral direction, and the second cylindrical portion is provided with a second shaft hole penetrating in a lateral direction.

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.

Strap arrangement comprising a first strap portion comprising a plurality of strap engaging structures, each strap engaging structure defines a size of an opening of the strap arrangement; a flexible second strap portion comprising at least one locking piece, the locking piece comprising at least one locking piece engaging structure for being aligned with at least one of the strap engaging structures; and at least one magnet adapted to force the locking piece engaging structure against at least one of the strap engaging structures by a magnetic force.

Disclosed is a buckle including a first connector member provided with a plurality of connecting grooves, and a second connector member provided with a plurality of connecting hooks protruding from the second connector member. While the first connector member and the second connector member are slid in a lateral direction by a first locking protrusion formed on one end portion of the first connector member and a second locking protrusion provided at a center portion of the second connector member, the first and second connector members are connected or disconnected, thereby quickly and readily connecting and disconnecting the buckle within a short stroke distance only by manipulation.

According to one of various aspects of the present invention, a side-release buckle includes a plug and a socket for inserting and engaging the plug, and when a cross section of the engaging surface is observed from an in-plane direction of the first mold mating surface defined by a first parting line of the plug, and from an direction perpendicular to an insertion direction, a surface to be engaged is located on the opposite side to a first belt winding portion with respect to the first mold mating surface, and has a first engaging surface forming an angle A.sub.1 with the first mold mating surface of 87 or more and 90 or less.

A connector device includes a connector component and a housing body. The connector component has a connector head. The housing body includes a first body portion and a second body portion. The first body portion has an accommodating space for the connector head. The second body portion is coupled to the first body portion and is rotatably movable with respect to the first body portion, wherein the second body portion has a first position and a second position. When the second body portion rotates to the first position, access in and out of the accommodating space is allowed for the connector head. When the second body portion rotates to the second position, the second body portion blocks the connector head access into or out of the accommodating space.
