Patent Application

The present invention relates to a belt buckle and more particularly to a belt buckle that enables the belt body to easily slide out thereof.
A belt for clothing basically comprises a long narrow belt body, and a metal buckle is fixed at one end of the belt body. The buckle has a frame, and a prong is pivotally arranged on one end of the frame, and a free end of the prong is pressed against the buckle. A plurality of punch holes are arranged on the other end of the belt body, so that after the belt body passes through the buckle to form a loop, the prong is selectively inserted into one punch hole to fasten the belt at a comfortable position for a user.
However, the conventional belt has following disadvantages: to remove the belt, a user needs to apply force to pull the belt in the opposite direction of original entry and pull the prong out of the punch hole of the belt at a specific angle and then pull the belt out from the buckle, which is inconvenient for use. Therefore, there remains a need for a new and improved design for a belt buckle to overcome the problems presented above.
The present invention provides a belt buckle which comprises a buckle cooperating with a belt body. The belt body comprises a connecting portion formed at one end thereof, and a plurality of punch holes arranged at the other end of the belt body. The buckle has a frame, a spring, a prong, a control unit, and a cover, and a shaft is located at one end of the frame. The shaft of the frame is adapted to pivotally connect to the connecting portion of the belt body, and a connecting base is formed at the other end of the frame. The spring is installed in the connecting base, and an open groove is formed at a middle section of the connecting base. One end of the prong is pivotally connected to the shaft while the other end thereof is formed into a hook portion configured to penetrate through one of the punch holes. The control unit is slidably arranged in the connecting base, and an abutting block is connected to the control unit, and the spring is coupled between the connecting base and the control unit. The cover is locked on the connecting base so as to limit the positions of the spring and the control unit. The abutting block is exposed out of the connecting base so as to be pressed to move the control unit. The control unit comprises a dodging slot and a blocking portion located at positions corresponding to the open groove. When the spring is not compressed by the control unit, the blocking portion is adapted to block the open groove so as to prevent the hook portion of the prong from passing through the open groove. When the control unit is moved to compress the spring, the dodging slot is aligned with open groove such that the hook portion of the prong is configured to pass through the dodging slot and the open groove, and the belt body is adapted to quickly slide out of the buckle when the abutting block is pressed.
In one embodiment, an accommodating slot is formed in the connecting base, and the control unit has a locating slot, and the spring is accommodated in and between the accommodating slot and the locating slot so as to limit the working space of the spring.
In another embodiment, a surface of the blocking portion of the control unit, which is faced to the cover, is formed into an inclined plane, and the cover has a notch faced to the open groove, so that the hook portion of the prong is adapted to pass through the notch to press against the inclined plane of the control unit; the hook portion is configured to control the control unit to press against the spring, and the prong is adapted to directly pass through the open groove so as to enable a user to quickly secure the belt body with the buckle.
In still another embodiment, the connecting base has a protruding bar, and a sliding groove is formed between the abutting block and the control unit; the sliding groove is adapted to couple with the protruding bar so as to enable the control unit to slide along the protruding bar.
Comparing with conventional belt buckle, the present invention is advantageous because: When the belt body needs to be loosed from the buckle, a user only needs to push the abutting block of the control unit, and the control unit is adapted to slide along the protruding bar to press the spring. The shift of the control unit enables the dodging slot to align with the open groove of the connecting base, and then the hook portion of the prong can directly pass through the open groove, the dodging slot, and the notch of the cover, so that the belt body is adapted to directly slide out of the buckle, thereby achieving the quick loosen effect.
