In various example embodiments, devices, systems, and methods for a waist measuring belt are provided. An example waist measuring belt is made up of a belt buckle frame with attachments for a belt strap. The belt further includes a position measuring module coupled to the belt buckle frame that measures an attachment position of a second end of the belt strap to the belt buckle frame. The belt also includes a tension measuring module coupled to the belt buckle frame that measures a tension through the belt buckle frame and the belt strap. A memory and a wireless communication module attached to the belt may be used to store measurements and communicate with a mobile device or server. In various embodiments, estimated user waist sizes over time using measured values and belt-specific data may be used to estimate a user's waist size and generate a waist size history.

A kit of pieces is provided comprising a buckle (1), a pair of braces and at least one elongate guide stick. The buckle comprises a first portion (2), a second portion (3), and a clamp portion (4). The first portion (2) is situated in front of the second portion (3) when the buckle (1) is in use. The clamp portion (4) is configured to clamp a first end of a belt against the second portion (3), and the first portion (2) is configured to clamp a second end of the belt against the second portion (3). Further, the first portion (2) comprises at least one groove (6).

The present application includes embodiments for a belt adjustment system. The belt adjustment system can be configured to engage a belt comprising a plurality of belt teeth. The belt engagement system can include a buckle portion that includes a belt clamp configured to couple the belt to the buckle, a lever pivotally movable between a first position and a second position, and a belt-engaging tab, the tooth-engaging tab positionable between a tooth-engaging position and a tooth-disengaging position responsive to the position of the lever on. The belt adjustment system can include a tool housing having a first wall and a second wall that form a slot. A tool comprising a distal end and a proximal end can be coupled to the tool housing, the tool positionable within the slot between a closed position and an open position.

A luminous spring buckle device includes a hollow casing, a luminous device, a spring and a bearing device. The hollow casing includes a bottom and an upper opening. The luminous device is positioned in the hollow casing and includes a controlling circuit and a luminous component. The spring is contained in the hollow casing. The bearing device is engaged with the upper opening in a sliding manner and coupled to the spring. Wherein, when an external force is applied to the bearing device, the bearing device compresses the spring and presses the controlling circuit to enable the luminous component to emit light. Compared with the prior art, the luminous spring buckle device includes the function of the spring buckle and luminous function to increase the recognizability and the night warning function.

A buckle with a whistle includes: a plug member having lock arms extending forward from both sides of a base and a guide rod extending forward from the base in such a way as to be located between the lock arms; and a socket member having a chamber open on the front end thereof by means of an upper plate and a lower plate located to face each other so that the socket member is coupled to the plug member. The chamber is allowed to accommodate the guide rod therein. The guide rod is configured as the whistle. When the plug member is coupled to the socket member, the whistle is accommodated in the chamber.

A removable, adjustable strap that secures around a television screen when a sports ticker is present and blocks the ticker from being visible on the screen.

The present disclosure relates to a buckle assembled with a whistle, the buckle including: a plug member having locking arms that are formed at both ends at a front side of a base, and a guide rod that protrudes from the base at an intermediate side between the locking arms; and a socket member having a guide groove which is formed at a center of the socket member so as to be opened at an upper side thereof to accommodate the guide rod at the center, and chambers which are formed at both sides of the guide groove so that the locking arms at the both ends are inserted into the chambers, in which the guide rod is configured as the whistle.

A buckle, such as for a strap or belt, houses a compact multi tool that is removable from the buckle. The arrangement includes a retention mechanism so the removable multi tool stays secure even with excessive body motion. The buckle can be any type of buckle for a belt or other type of strap. The buckle can couple a belt or strap to itself to create a loop or can couple strap portions to one another. The buckle functionality can be provided by any suitable arrangement, such as a cam lock mechanism, a pin or post-in-hole arrangement or a snap-fit arrangement, for example and without limitation. The multi-tool can include one or more articulating (e.g., foldable) tool elements. In some configurations, the multi-tool comprises a sleeve that receives a body of the multi-tool. The sleeve can include tool features.

A attachment system is formed by a primary device and a secondary device connected to the primary device in a pivoting manner. The primary device has a main body, two lateral sides and a bar for attaching the primary device to another object. Each of the lateral sides has a protrusion extending laterally outward from the lateral sides. The secondary device has two lateral sides, each equipped with an aperture that corresponds to one of the protrusions on the primary device, so that fitting the protrusions into the apertures pivotally connects the primary device to the secondary device, with the lateral sides of the secondary device being disposed outside of the lateral sides of the primary device. The secondary device can be pivoted between a folded position where the secondary device lies against the primary device, and an open position where the secondary device is raised up.
