[0019] All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention. The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.
[0020] In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:
[0021] Referring to FIGS. 1 to 4, the present invention provides a belt buckle which comprises a buckle (20) cooperating with a belt body (10). The belt body (10) comprises a connecting portion (11) formed at one end thereof, and a plurality of punch holes (12) arranged at the other end of the belt body (10). The buckle (20) has a frame (21), a spring (22), a prong (23), a control unit (24), and a cover (25), and a shaft (211) is located at one end of the frame (21). The shaft (211) of the frame (21) is adapted to pivotally connect to the connecting portion (11) of the belt body (10), and a connecting base (26) is formed at the other end of the frame (21). The spring (22) is installed in the connecting base (26), and an open groove (261) is formed at a middle section of the connecting base (26). One end of the prong (23) is pivotally connected to the shaft (211) while the other end thereof is formed into a hook portion (231) configured to penetrate through one of the punch holes (12). The control unit (24) is slidably arranged in the connecting base (26), and an abutting block (241) is connected to the control unit (24), and the spring (22) is coupled between the connecting base (26) and the control unit (24). Moreover, an accommodating slot (262) is formed in the connecting base (26), and the control unit (24) has a locating slot (242), and the spring (22) is accommodated in and between the accommodating slot (262) and the locating slot (242) so as to limit the working space of the spring (22). The cover (25) is locked on the connecting base (26) so as to limit the positions of the spring (22) and the control unit (24). The abutting block (241) is exposed out of the connecting base (26) so as to enable a user to press the abutting block (241) to move the control unit (24). Furthermore, the connecting base (26) has a protruding bar (263), and a sliding groove (243) is formed between the abutting block (241) and the control unit (24). The sliding groove (243) is adapted to couple with the protruding bar (263) so as to enable the control unit (24) to slide along the protruding bar (263), and the cover (25) is configured to keep the control unit (24) coupling with the protruding bar (263). In addition, the control unit (24) comprises a dodging slot (244) and a blocking portion (245) located at positions corresponding to the open groove (261). When the spring (22) is not compressed by the control unit (24), the blocking portion (245) is adapted to block the open groove (261) so as to prevent the hook portion (231) of the prong (23) from passing through the open groove (261). On the other hand, when the control unit (24) is moved to compress the spring (22), the dodging slot (244) is aligned with open groove (261) such that the hook portion (231) of the prong (23) is configured to pass through the dodging slot (244) and the open groove (261), and the belt body (10) is adapted to quickly slide out of the buckle (20) when the abutting block (241) is pressed. Additionally, a surface of the blocking portion (245) of the control unit (24), which is faced to the cover (25), is formed into an inclined plane (246), and the cover (25) has a notch (251) faced to the open groove (261), so that the hook portion (231) of the prong (23) is adapted to pass through the notch (251) to press against the inclined plane (246) of the control unit (24). Thus, the hook portion (231) is configured to control the control unit (24) to press against the spring (22), and the prong (23) is adapted to directly pass through the open groove (261) so as to enable a user to quickly secure the belt body (10) with the buckle (20).
[0022] In actual application, referring to FIGS. 2 to 8, the frame (21) of the buckle (20) is connected to the connecting portion (11) of the belt body (10) through the shaft (211), and the prong (23) is pivotally connected to the shaft (211), and the hook portion (231) of the prong (23) is faced to the connecting base (26) of the frame (21). Also, the spring (22) is arranged in the accommodating slot (262) of the connecting base (26), and the control unit (24) is installed in the connecting base (26). Moreover, the spring (22) is borne against the locating slot (242) of the control unit (24), and the sliding groove (243) of the control unit (24) is coupled with the protruding bar (263) of the connecting base (26), and the abutting block (241) is exposed out of the connecting base (26). Then, the connecting base (26) is locked on the cover (25) to complete the assembly. When the belt body (10) is to be buckled, the end of the belt body (10) having the punch holes (12) is configured to pass through the frame (21) of the buckle (20), and the hook portion (231) of the prong (23) is adapted to penetrate through one of the punch holes (12). Also, the hook portion (231) is positioned at the open groove (261) of the connecting base (26) to abut against the blocking portion (245) of the control unit (24) so as to fasten the belt body (10) with the buckle (20) at a comfortable position for a user. When the belt body (10) needs to be loosed from the buckle (20), a user only needs to push the abutting block (241) of the control unit (24), and the control unit (24) is adapted to slide along the protruding bar (263) to press the spring (22). The shift of the control unit (24) enables the dodging slot (244) to align with the open groove (261) of the connecting base (26), and then the hook portion (231) of the prong (23) can directly pass through the open groove (261), the dodging slot (244), and the notch (251) of the cover (25), so that the belt body (10) is adapted to directly slide out of the buckle (20), thereby achieving the quick loosen effect.
[0023] Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
