Abstract: A buckle assembly includes a first plate and a second plate defining a gap therebetween. A button assembly defines a slot aligned with the gap, and is coupled to the first plate and the second plate for movement along a longitudinal axis of the first plate. The button assembly includes a door transversely moveable relative to the longitudinal axis between a closed position covering the slot and a retracted position spaced from the slot. The door includes an angled ledge, that directs fluid through at least one aperture in a sidewall of the button assembly when the door is in the closed position. A block is disposed within the gap. The first plate and the second plate define undulations extending along the longitudinal axis and into the gap. The block mates with the undulation in the first plate and the second plate to fill the gap.

Abstract: A strap buckle apparatus fastened to a lock hole is employed to connect to a strap. The strap buckle apparatus comprises a rotation hub, a base, and a rotation plug. The rotation hub controls the rotation angle of the rotation plug. The base with a hole in the center connects to a strap. One end of the rotation plug is inserted into the lock hole, while the other end is fixed to the rotation hub.

Abstract: A fastener for fastening a strap to an article having an end pin attached thereto, the fastener having a retention portion and an engagement portion defining a fastener aperture where movement of the engagement portion relative to the retention portion acts to close the fastener aperture about a reduced diameter portion of the end pin. A locking mechanism restricts movement of the engagement portion thereby maintaining the fastener aperture in its engagement position.

Abstract: A buckle includes a base frame 10, a latch plate 30, a locking wing 40 and an ejector 20. The base frame 10 is formed with a tongue insertion path 12 through which a tongue plate 2 is inserted. The latch plate 30 is pivotally supported on an upper surface of the base frame 10, having a latch pawl 33 formed at a front end and an operational arm 32 formed at a rear end, which is applied with pivoting force by the end of the tongue plate 2 when the tongue plate 2 is inserted. The locking wing 40 is structured to maintain the locked state by biasing force of a locking spring 37 between the locking wing 40 and the latch plate 30 and by an engagement between the locking wing 40 and locking pawl 33. The locking wing 40 is also structured to release the engagement between the locking wing 40 and the locking pawl 33 by a movement of a press button 52. The ejector 20 is supported slidably in the tongue insertion path 12 and biased by an ejector spring 21.

Abstract: A device for releasably gripping a shaft has a body with a central channel for receiving the shaft. The device also has an arrangement, mounted to the body, for gripping and releasing the shaft when a member of the arrangement, is respectively in first and second positions with respect to the body. A sleeve is disposed concentrically outside of the body, and is mounted for axial movement with respect to the body in such a manner as to cause axial movement of the member, so axial movement of the sleeve in a first direction will achieve release of the shaft. In this manner, one may grip the sleeve and, in a single motion, achieve release of the shaft and slide the device relative to the shaft.

Abstract: A hand releasable locking collar to secure objects or itself in a desired location on a shaft, bar or the like. The device comprises a housing, end cap, preload spring and clutch plate conformed to the shaft. The clutch plate is rotatably assembled within the device such that said device is free to move axially on the shaft when the clutch plate is positioned perpendicular to the axis of the shaft. When released, said clutch plate allows further tightening of the device by moving axially in the direction installed, but locks positively to prevent removal or movement in the opposite direction unless such clutch plate is again moved to the position of perpendicularity with the axis of the shaft.
