Abstract: A connector system is formed from a female portion and a male portion that slides within the female portion. The female portion has a base body, a channel, and a protrusion extending into the channel. The male portion has a base body with a locking flange extending along one longitudinal edge thereof. The spring has an aperture for receiving the protrusion when the flange is inserted into the channel. There is an actuating device connected to the spring and configured for depressing the spring. The male portion is connected to the female portion by sliding the flange into the channel until the protrusion extends through the aperture in the spring. The male portion is released from the female portion by pulling the actuating device to depress the spring until the protrusion clears the aperture, and then sliding the male portion out of the channel.

Abstract: A system for attachment to webbing has an attachment portion and an operating portion that can be attached to and detached from each other. The attachment portion has a base body with a cavity, a transverse bar, and two locking hooks. The operating portion has two side legs, top sections connected to the side legs, a gap between the top sections and a locking hook on each of the top sections. The operating portion is connectable to the attachment portion by pressing the legs together and inserting the locking hooks of the operating portion into the base body, and then releasing the legs so that the locking hooks of the attachment portion and operating portion engage each other. The operating portion is detachable from the attachment portion by squeezing the legs together until the locking hooks on the operating portion clear the locking hooks on the attachment portion.

Abstract: An attachable surface cover for a USB port has a casing and a base plate. The casing has an attachment component. The casing is attached to a piece of cloth by means of the attachment component penetrating through the cloth. The attachment component is detachably connected to the base plate. The attachable surface cover for a USB port has a plug hole for insertion and removal of a USB cable. An entrance of the plug hole is on the casing. An exit of the plug hole is used to configure a USB port. The attachable surface cover for a USB port of the present invention has a reasonable design and is highly practical.

Abstract: An eyelet button and an assembly method thereof, in which the eyelet button is formed of an eyelet button body and a base plate for fastening with the eyelet button body. The eyelet button body is formed from an eyelet tube, a body peripheral portion formed by everything at one end of the eyelet tube in an axial direction, and a plurality of inverted fasteners formed by everting at the other end of the eyelet tube in the axial direction. The base plate is formed of a base plate body, with a mounting hole with an inner wall having a plurality of protruded tooth portions. A gap is formed between two adjacent protruded tooth portions. When the eyelet tube passes through the mounting hole, the inverted fasteners pass through the gaps to rotate with the eyelet tube so as to be connected and fixed to the corresponding protruded tooth portions.

Abstract: A buckle portion has a buckle body, at least one elastic locking leg connected to the buckle body, and a locking element comprising a plate having an actuation element. The locking element is connected to the elastic locking leg and is movable relative to the elastic locking leg by moving the actuation element between a locked position and an unlocked position. In the unlocked position, the elastic locking leg is movable so as to release the buckle portion from a corresponding buckle receptacle. In the locked position, the locking element prevents flexing of the elastic locking leg even under external pressure to keep the buckle portion from being released.

Abstract: A cord fastener has a cord fastener main body and a bottom plate provided with at least two linear sliding holes, and a first bulge formed on an inner wall of a sliding terminal of the sliding hole. The linear sliding holes are arranged such that distances from two end faces of the bottom plate respectively to the first bulge are different. 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 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 swivel snaphook has a hook and a retainer. The retainer has a support portion and a strap mounting portion. The support portion has a base body connected to the strap mounting portion, a through hole passing through the base body, and a snap-in portion protruding from the surface of the base body and surrounding the through hole. The hook has a hook and connector portion and an engaging portion. The engaging portion has a connecting shaft connected to the hook and connector portion, and a snap-on portion. When the hook and the retainer are snap-fitted together, the snap-on portion surrounds the snap-in portion and fits with the snap-in portion in an inverted manner.

Abstract: An adjusting strap adjusts the tube orifice diameter of a flexible tube-shaped object and has an inner annular wall, an outer annular wall, and an interlayer between the inner annular wall and the outer annular wall. The adjusting strap has a head portion, a tail portion, and a flexible rope strap portion between the head portion and the tail portion. The tail portion comprises a tail housing, and an avoidance hole passing through the tail housing and available for the head portion and the rope strap portion to pass through. When the adjusting strap is mounted in the flexible tube-shaped object, the head portion passes through the avoidance hole and penetrates the outer annular wall of the flexible tube-shaped object, the rope strap portion is partially received in the interlayer, and the tail portion is completely received in the interlayer and is connected to the flexible tube-shaped object.

Abstract: 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.

Abstract: A swivel connector has a female part and a male part that are connected to each other so as to swivel. The female part has a main body with an interior cavity and an open face, and a strap connector. The male part has a plug portion and a strap connector. A ring lock locks the male portion to the female portion and is formed by two side walls connected by two pivot bars, the side walls of the ring lock being rotatably connected to the female part. The male part is locked to the female part by inserting the plug portion into the interior cavity, and the ring lock is held by spring in a locked position where the open face is blocked by one of the pivot bars. The male part is released from the female part by rotating the ring lock against the force of the spring until the open face is not blocked by the pivot bar.
