BRIDGE-ADJUSTMENT FIXING BELT BUCKLE

Abstract

A bridge-adjustment fixing belt buckle is provided, aiming to improve difficulty of adjustment and unstable fixing. A first bridge, which is rotatable, is arranged in conjunction with a spring and a raised pawl to achieve quick and stable fixing and tightness adjustment of a belt. To avoid accidental touch, the bridge is arranged to drive the raised pawl to disengage from the belt, and automatic position restoration is achieved by the elastic force of the spring. Outside appearance change made with an auxiliary bridge may change the position of triggering the raised pawl to provide flexibility for expansion of mechanical design and also maintaining smooth feel of adjustment. Also, a combination of a main limiting frame, a decorative panel control, and a connecting seat can be used to achieve horizontal push type operation, and a more accurate and stable tightness adjustment is achieved in conjunction with the belt ratchet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] The present invention provides a bridge-adjustment fixing belt buckle (FIGS. 1-6), which comprises: a belt buckle seat (10), of which a center is pivotally connected with a first bridge (11) that is rotatable for adjustment. A raised pawl (111) extends from the first bridge (11). A spring (112) is arranged between the raised pawl (111) and the belt buckle seat (10) for elastic position restoration of the first bridge (11) and the raised pawl (111). The material of the spring (112) can be changed (such as rubber and elastic plastic). Additional arrangements for combination of the spring (112) and the raised pawl (111) with a belt (40) may refer to the ratchet types in FIGS. 15-16, in order to realize that the usable types of the belt (40) are wider, and thus, using the elastic position restoration of the spring (112) can achieve effective fixation.

[0025] A decorative panel control (20) is connected to one side of the belt buckle seat (10), and a second bridge (21) is provided on the other side. When the belt (40) extends through the second bridge (21) and the first bridge (11) to an appropriate position, the spring (112) drives the first bridge (11) to restore position, and the raised pawl (111) presses against the belt (40) for fixing. To adjust or remove the belt (40), the first bridge (11) is pushed so that the raised pawl (111) is caused to move downward to a non-pressing state, and the belt (40) can then be smoothly adjusted, thereby improving the convenience of operation. The decorative panel control (20) can be changed with a decorative pattern or added with an ergonomic curved surface to further enhance the comfortableness of operation.

[0026] First additional embodiment (FIG. 7): The belt buckle seat (10) is pivotally connected, at one side adjacent to an edge thereof, to a first bridge (11), and a raised pawl (111) extends from the first bridge (11), and a spring (112) is arranged between the raised pawl (111) and the belt buckle seat (10) to provide elastic position restoration of the first bridge (11) and the raised pawl (111) (the structure being the same as the previous example). One side of the decorative panel control (20) is provided with an auxiliary bridge (30) connected to the center of the belt buckle seat (10), and the other side is provided with a second bridge (21). To adjust the tightness of the belt (40), the first bridge (11) is pushed and rotated to release the fixing of the belt (40) by the raised pawl (111), so as to facilitate the subsequent operation of adjustment. After completion, the spring (112) restores the position to fix.

[0027] Second additional embodiment (FIGS. 8-10): The decorative panel control (20) is pivotally arranged at the center of the belt buckle seat (10) and is provided, on the inner sides of two ends thereof, with a second bridge (21) and an auxiliary bridge (30) respectively, with a limiting groove (22) arranged therebetween. The first bridge (11) is pivotally arranged on two sides of a convex portion (100) on an outside of the belt buckle seat (10) and in driving coupling with the spring (112) arranged in the interior of the belt buckle seat (10) to press against the raised pawl (111). The material of the spring (112) can be changed (rubber or elastic plastic), and the thickness of the limiting groove (22) is greater than the thickness of the first bridge (11). An arc-shaped portion (110) is provided on an edge of the first bridge (11) to cooperate with the convex portion (100) to enable the first bridge (11) to rotate smoothly within a specific angle. To adjust the tightness of the belt (40), the first bridge (11) is pushed and rotated to release the fixing of the belt (40) by the raised pawl (111), so as to facilitate the subsequent operation of adjustment. After completion, the spring (112) restores in position to resume fixing.

[0028] Third additional embodiment (FIG. 11): The middle of the decorative panel control (20) has a modified shape, while the remaining of the structure is unchanged. Fourth additional embodiment (FIG. 12): The position of the limiting groove (22) is different. Through adjusting the position of the limiting groove (22), the position where the belt (40) extends through the decorative panel control (20) can be used with different shapes and sizes, and the center of gravity of the belt (40) can obtain the best balance point when the belt (40) is fixed. Fifth additional embodiment (FIG. 13): The decorative panel control (20) is further provided with a third bridge (50) which is arranged in parallel with the second bridge (21) so as to modify the strength that the raised pawl (111) press against and connect with the belt (40). Since the third bridge (50) and the second bridge (21) are lower than the raised pawl (111), the pressing force of the raised pawl (111) is more powerful, and the inner side of the decorative panel control (20) can be designed in full plate to hide the belt (40), also achieving the purpose of shape modification.

[0029] Sixth additional embodiment (FIGS. 14-16): a main limiting frame (70) is provided, which is provided with a limiting groove (71) at a center thereof, and the main limiting frame (70) is provided, on one side thereof, with a main first bridge (72) and is also provided, on the other side thereof, with a connecting portion (73), and the first bridge (72) is provided for a belt (40) to extend therethrough.

[0030] The decorative panel control (20) comprises a main shaft rod (80) and a decorative panel portion (83). A main shaft rod raised pawl (81) extends from the main shaft rod (80). A spring (112) is arranged on a bottom of the raised pawl (81). The main shaft rod raised pawl (81) can also be replaced with a material having resistance characteristics to press against the belt (40) in order to adapt to different types of belts (40). The decorative panel control (20) is arranged inside the limiting groove (22), and the width of the decorative panel control (20) is smaller than the width of the limiting groove (22), so as to ensure that the elastic force of the spring (112) is sufficient to drive the decorative panel control (20) to adjust operation, and a pattern can be attached to the decorative panel control (20) by means of engraving, printing, and three-dimensional modeling.

[0031] One side of a connecting seat (75) is provided with a pivoting portion (76) for connection with the main shaft rod (80), and the other side is provided with a positioning groove (77), and a connecting groove (79) is provided on an upper side thereof for connection with the connecting portion (73). A positioning member (78) is embedded in the positioning groove (77), and the main limiting frame (70) is completely fixed to the connecting seat (75) and also forms a main second bridge (74) on the opposite side of the main first bridge (71), so that a wearer can push horizontally and control the decorative panel control (20) to drive the main shaft rod raised pawl (81). Specifically, the main shaft rod raised pawl (81) cooperates with a ratchet (41) of the belt (40) for pressing and positioning, so as to make adjustment of tightness of the belt (40) between the main first bridge (72) and the main second bridge (74) easier and more stable.

[0032] In summary, compared with general belt buckles, the present invention utilizes an integrated and linked arrangement of a bridge and a raised pawl to reduce the number of parts and reduce the complexity of design, thereby forming a belt buckle with a simple structure, convenient operation, and diversification of appearance, which meets the needs of fashion and functionality, and improves the smoothness of the adjustment operation through the arrangement of auxiliary bridge, greatly improving the durability.
