A child safety assembly includes a wristband that is selectively worn around a child's wrist. A lock is movably coupled to the wristband and the lock is selectively manipulated. The lock is selectively positioned in a locked position to retain the wristband on the wrist. The lock is selectively positioned in an unlocked position to facilitate the wristband to be removed from the wrist. An alert unit is coupled to the wristband and the alert unit is in thermal communication with the wristband's environment. The alert unit selectively emits an audible alarm and the alert unit is in wireless electrical communication with an electronic device. The alert unit emits the audible alarm when the alert unit detects a temperature of the wristband's environment falls below or rises above a trigger temperature. In this way the alert unit alerts a caregiver to a potential hazard with respect to the child.

In a clasp (1), a male member (2) has a columnar insertion portion (23) and a female member (4) has a cylindrical housing portion (43). The clasp (1) has magnets which attract the insertion portion (23) into the housing portion (43). A male engagement body (3) is provided on an outer peripheral surface (23a) of the insertion portion (23) of the male member (2) while a female engagement body (5) is provided on an inner peripheral surface (43a) of the housing portion (43) of the female member (4). The male engagement body (3) and/or the female engagement body (5) is provided as a long protruding edge structure or a long recessed notch structure along the axis of the clasp (1), has a guiding portion (53), and also has a retaining portion (52) which prevents the insertion portion (23) from getting out of the housing portion (43).

A watch band includes a strap and a clasp mechanism integrated with an end of the strap. The clasp mechanism includes a concave member defining a channel at the end of the strap and a cover plate. The cover plate is configured to move between (i) a first position in which the cover plate covers the channel, and (ii) a second position in which the cover plate is retracted to leave at least part of the channel uncovered by the cover plate.

A band latch mechanism that is configured to connect a wristband to a fitness tracker is provided. The band latch mechanism may be configured to be inserted into a cavity of a housing of the fitness tracker and configured so that any metallic body of the band latch mechanism does not contact metallic surfaces of the cavity in order to prevent an electrical ground from being positioned within a keep-out zone of an antenna of the fitness tracker.

A wristband with straps having a fixed-position keeper and a tang buckle with an elongate-hole tang is provided. The elongate hole may permit the tang to slide for a limited distance along the length of the buckle strap, thereby accommodating different wrist sizes and shapes while reducing the possibility of bridging or tang lift in the band.

A jewelry item has a first side including a first and second end with a stem and locking notch and a second side including a third and fourth end with a mounting stem and ball joint. The second end of the first side is connected to the fourth end of the second side. A closure has a collar rotatably connected to a rotatable connection element. The collar is connected to the third end and located between the third end and the rotatable connection element. In an open configuration, the stem with the locking notch of the first side can be inserted within a locking cavity of the rotatable connection element. In a closed configuration, the rotatable connection element is configured to be rotated to engage the locking notch of the stem, preventing removal of the stem from the rotatable connection element.

A watch band can provide both a physical connection and an electrical connection with a watch body of a watch. The watch band is fixed relative to the watch body and an electrical connection is either performed either simultaneously or shortly thereafter. The electrical connection enables data and power transfer between the watch body and the watch band. The electrical connection can also be performed by a secondary user interaction. Secondary user inactions can involve the user sliding, pulling, pushing, or rotating a portion of the watch band or watch body.

The invention provides a connection structure including: a first subassembly and a second subassembly each including a first side edge. A first tubular body and a second tubular body are fixedly connected to the first side edge of the first subassembly, and a third tubular body is fixedly connected to the first side edge of the second subassembly; a gap is disposed between the first tubular body and the second tubular body and is configured to accommodate the third tubular body. The connection structure of the invention has a simple and rational design, low production cost, and is easy to assemble and disassemble. The assembly and disassembly of the connection structure can be achieved using conventional tools, without the involvement of operations from professionals, and the connection is highly efficient. The connection structure is particularly practicable for manufacturing different components of jewelry. Through the connection structure, a user can freely combine and match different kinds of jewelry components with each other to form different styles to conform to his or her preferences; in addition, the components of different jewelries can be randomly exchanged as needed, so the connection structure can be used in a broad range of scope.

To provide a clasp that is capable of satisfying both of operational convenience and freedom in design when provided to an accessory or the like.

In a clasp 1 including a male member 2 consisting of a columnar insertion portion 23, and a female member 4 including a cylindrical housing portion 43 housing the insertion portion 23, the insertion portion 23 and the housing portion 43 each include attraction members arranged to attract the insertion portion 23 into the housing portion 43 by magnetic attraction force. A male engagement body 3 is provided on an outer peripheral surface 23a of the insertion portion 23 of the male member 2 while a female engagement body 5 is provided on an inner peripheral surface 43a of the housing portion 43 of the female member 4. At least one of the male engagement body 3 and the female engagement body 5 is provided as a long protruding edge structure or a long recessed notch structure along the axes of the insertion portion 23 and the housing portion 43, and includes a guiding portion 53 arranged to guide the other, and also includes a retaining portion 52 capable of preventing, by being locked to the other, the insertion portion 23 from getting out of the housing portion 43.
