At least two fixing feet are provided on the cord fastener main body and the fixing foot is provided with a second bulge configured to abut the first bulge after the fixing foot passes through a positioning hole in a piece of cloth and the corresponding sliding hole in the bottom plate in sequence.

Abstract: A closure system has a main body having a hollow cavity, a locking mechanism slidably disposed within the cavity, and a plurality of fastening elements. The locking mechanism is formed of a central post, a plurality of engagement pins connected to the central post, and an actuator, such that pulling the actuator causes the locking mechanism to move between a locked and unlocked position. Each fastening element has an aperture for connecting to the locking mechanism by inserting the fastening element into the cavity while the locking mechanism is in the unlocked position, and then pushing the actuator to slide the locking mechanism into the locked position. All of the fastening elements can then be released simultaneously from the locking mechanism by pulling the actuator to slide the locking mechanism from the locked position to the unlocked position.

Abstract: A cord lock has a housing with an interior cavity and an opening extending between the front and the back for receiving a cord, and an actuator having two legs that are configured to slide within the interior cavity of the housing. A spring is disposed between the housing and the actuator to bias the actuator in a raised position relative to the housing. There is a cam disposed in the interior cavity of the housing. The bottom of the cam is rotatably connected to the housing and the top is rotatably connected to the legs of the actuator. In a resting position, the spring presses the top of the cam against the housing such that when a cord is extended through the opening, the cam locks the cord in place between the cam and the housing. Depressing the actuator compresses the spring and rotates the cam.

Abstract: A strap adjustment system has a base body having a bottom wall, two side walls and a strap retaining bar extending between the two side walls, the bottom wall having an aperture therethrough with screw threads extending around an inside surface, and a screw disc having a central protrusion and screw threads extending around the central protrusion. The central protrusion fits through the aperture in the base body by rotating the screw disc so that the threads in the screw disc mate with the threads in the aperture, such that a height of the protrusion above the bottom wall of the base body is adjustable by turning the screw disc. In situations where a high degree of friction is required, the protrusion can be positioned at a maximum height through the aperture, and in situations where a low degree of friction is desired, the protrusion can be positioned lower.
