In a cross-section perpendicular to the extending direction of a support part, a first bar has a holding part that holds a belt together with a leading end part and a winding part on which the belt is wound. A third bar is positioned on one side of a virtual line connecting a point at the holding part at which the belt is held together with the leading end part of a moving part and a point at the support part of the moving part before being moved. An operating part of the moving part extends from the support part to the other side relative to the virtual line , and a biasing part of the moving part generates biasing force in such a direction that the leading end part is moved toward the first bar.

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.

This disclosure relates generally to belt buckles and more particularly to belt buckles that have associated with the face or front thereof interchangeable initials, letters or other design. The working mechanics of the buckle is different than any other in the market. The said Buckle has a holding mechanism that won't damage the belt strap because the material that it uses it as explained throughout this patent application. The invention is based to facilitate the user for opening and closing of the belt. Moreover, the said Buckle allows what no any other Buckle allows and is for the strap to pass underneath of the fix portion of the strap, the result is the need not to the strap to be cut to the size of the waist of every individual. I will describe this as unique in today's dress belt market.

A luminous spring buckle device includes a hollow casing, a luminous device, a spring and a bearing device. The hollow casing includes a bottom and an upper opening. The luminous device is positioned in the hollow casing and includes a controlling circuit and a luminous component. The spring is contained in the hollow casing. The bearing device is engaged with the upper opening in a sliding manner and coupled to the spring. Wherein, when an external force is applied to the bearing device, the bearing device compresses the spring and presses the controlling circuit to enable the luminous component to emit light. Compared with the prior art, the luminous spring buckle device includes the function of the spring buckle and luminous function to increase the recognizability and the night warning function.
