A buckle assembly includes a first frame member defining a first slot, which includes a first open end positioned at a first side of the first frame member and which includes a first closed end positioned spaced apart from a second side of the first frame member; a second frame member defining a second slot, which includes a second open end positioned at a second side of the second frame member and a second closed end positioned spaced apart from a first side of the second frame member, wherein one of the first or second frame members has a pivot member upon which the first and second frame members are rotatable relative to one another; and a third frame member defining at least two slots which extend through the third frame member and is configured to position within a recess defined within the second frame member.

A buckle assembly with a disengagement prevention device and a method for using the same is disclosed. The buckle assembly has a first buckle member having a first strap holding structure configured to adjustably affix the first buckle member to a first strap segment. A second buckle member is configured to couple with the first buckle member, the second buckle member having a second strap holding structure configured to affix the second buckle member to a second strap segment. A disengagement prevention device is configured for engagement with the first and second buckle members to maintain the first and second buckle members in a coupled state under conditions where the first and second buckle members are not properly engaged or the engagement between the first and second buckle members is accidentally released.

A locking buckle comprising a first buckle member and a second buckle member. The first buckle member may comprise a first strap-receiving slot for receiving a first loop end of a strap, the first strap-receiving slot is defined in part by a strap-retaining bar and a body of the first buckle member and a strap-locking bar pivotably attached to the body of the first buckle member, the strap-locking bar pivotable between an unlocked configuration in which a strap may freely pass through the first strap-receiving slot and a locked configuration in which a strap passing through strap-receiving slot is prevented from passing freely through the first strap-receiving slot. The second buckle member is connectable to the first buckle member. The second buckle member comprises a second strap-receiving slot for receiving a second loop end of the strap.

Two methods to attach a webbing or ribbon to a quick release buckle, and a quick release buckle for the use of the two methods are disclosed. Quick release buckles are designed to be used with webbing that is sewn to be attached to the quick release buckle, but for this invention two methods that do not require a sewing process are disclosed. One method uses a knot, and the other method uses a melted-solidified-end made on the webbing or ribbon using a melting method such as a flame or a hot iron or an ultrasonic welder.

A buckle assembly includes a first frame member defining a first slot, which includes a first open end positioned at a first side of the first frame member and which includes a first closed end positioned spaced apart from a second side of the first frame member; a second frame member defining a second slot, which includes a second open end positioned at a second side of the second frame member and a second closed end positioned spaced apart from a first side of the second frame member, wherein one of the first or second frame members has a pivot member upon which the first and second frame members are rotatable relative to one another; and a third frame member defining at least two slots which extend through the third frame member and is configured to position within a recess defined within the second frame member.

A belt has a strap. A detachable buckle is attached to a first end of the strap. The detachable buckle has a base. A cutout is formed on a front surface of the base. A removable is faceplate inserted and held within the cutout. A ratchet mechanism secures a second end of the strap within the detachable buckle.

A second buckle member is configured to couple with the first buckle member, the second buckle member having a second strap holding structure configured to affix the second buckle member to a second strap segment. A disengagement prevention device is configured for engagement with the first and second buckle members to maintain the first and second buckle members in a coupled state under conditions where the first and second buckle members are not properly engaged or the engagement between the first and second buckle members is accidentally released.

A buoyancy control device for scuba diving comprising at least two shoulder straps, each shoulder strap having an upper portion and a lower portion joined by a closing buckle comprising a male buckle element and a female buckle element, which has a first connection means for connecting to the upper portion of the shoulder strap and a second connection means for connecting to the male buckle element, wherein the female buckle element comprises a first part that has the first connection means, a second part that has the second connection means, and an articulated connection pin for connecting the first part to the second part.

The present invention provides a strap adjustment device for connecting with a body of a mask. The strap adjustment device comprises a female element, an elastic strap, and a regulating device. The female element is disposed on one side of the body of the mask and has an opening and a slot. The elastic strap has a male element and an adjusting end portion, which is opposite to the male element. The male element has a shape which is substantially corresponding to the female element. The regulating device is connected to the adjusting end portion. When the strap adjustment device is assembled with the body of the mask, the adjusting end portion passes through the opening and the slot before passing through the regulating device in an adjustable manner and being engaged in place by the regulating device. The male element is located in and positioned in the opening.

A belt tongue (1) having a tongue body (3) extending in an insertion direction (2), forming a belt slot (4) for guiding a belt crosswise to an insertion direction (2), and a blocking element (5), movably arranged in the tongue body (3) The belt is movable through the belt slot (4) in an unloaded pass-through position of the blocking element (5) and its mobility is at least inhibited by the blocking element (5) in a loaded position, created by a tensile force introduced into the belt. The belt is deflected by the belt tongue (1) in the fastened state in a loop shape. A cover (6) is provided at least on one side of the tongue body (2) and is arranged having at least one partial section (7) under the belt slot (4), and the partial section (7) directly adjoins the belt slot (4) and covers at least one part of the blocking element (5) in the pass-through position.
