Abstract: A belt adjustment and fixation hook (1), comprising a body (10), a hook portion (11), a limiting convex portion (12) and a belt installation frame portion (13); the body (10) has a first main surface (101) and a second main surface (102) opposite thereto; the body (10) is provided with a first through hole (103); the limiting convex portion (12) is located in the first through hole (103) and extrudes beyond the first main surface (101) to limit a support rod (2); and the belt installation frame portion (13) is connected to the body (10) to further connect to a belt (3). The belt adjustment and fixation hook (1) fits the support rods (2) having different diameters; in addition, the belt adjustment and fixation hook (1) is convenient to detach and replace the belt (3), thus improving user experiences and reducing costs.

Abstract: A washer for use in a snap fastener is adapted to be placed over the lower part of a snap fastener component so that the washer rests between the fabric and the lower part of the snap fastener. The upper part of the snap fastener is placed over the fabric and is pressed into place by a tool press. The washer is made of a resilient material, such as plastic or rubber, which is then squeezed by the tool press to fill in any gaps that would allow water to leak through. In its unassembled state, the washer consists of a flat ring surrounding a center protrusion, which is hollow on its inside. To assemble the snap fastener, the center protrusion is placed over the central post of the lower part of the snap fastener. The central post with the washer is then inserted through a hole in the fabric to which the snap fastener is to be attached.

Abstract: A buckle assembly has a base portion with a strap retaining bar and an inner opening disposed between the side walls, and a locking portion having a strap retaining bar and a protrusion extending outwardly from each of the side walls. The length of the locking portion is greater than the length of the opening, and the width of the opening is wider than the width of the locking portion. The side walls of the base portion each have a slot arranged to accommodate the protrusions on the locking portion when the locking portion is placed on the base portion. The locking portion is connected to the base portion by sliding the locking portion through the opening from the bottom side to the top side of the base portion, aligning the locking portion to extend parallel to the base portion, and snapping the protrusions into the slots.

Abstract: A ratchet adjustment system has an elongated adjustment strip with teeth extending along the strip. The teeth form a ratchet mechanism when ends of the strip are inserted into a locking mechanism having a base plate and locking devices. The strip ends are inserted into the locking devices from opposite directions, so that the system forms a closed circle. The circumference of the system is reduced by pressing opposite sides of the strip together so that the insertion ends are inserted further through the locking devices, and the circumference is increased by pulling the strip away from the locking devices. Depending on the geometry of the teeth and locking devices, the amount of force needed to reduce and increase the circumference could be equal, or the amount of force required to reduce the circumference could be less than the amount required to increase the circumference.

Abstract: A cord end has a main body with a bottom surface and a top surface and a covering portion attached to the main body that can be folded over the bottom surface and secured to the bottom surface. The main body has two cord-receiving apertures therein. Each aperture has a cord-securing slot in communication with the apertures, such that a cord is secured to the cord end by threading the cord from the bottom surface, through one aperture, across the top surface and through the other aperture and out the bottom surface, pulling the cord so that the cord slides into the cord securing slots, and snapping the covering portion over the bottom surface.
