Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The invention relates to a buckle structure, more particularly, to a buckle structure between an upper cover and a box body of a leather suitcase, a traveling case or a brief case.
2. Description of the Related Art
For a general leather suitcase or a traveling case, one or two buckles are often disposed between a box body and an upper cover thereof in order to locate the upper cover when closing it and make it difficult to be opened. The upper cover can not be opened by means of the buckling of the buckle.
A known buckle provides a lateral locking effect. A male and a female buckle are disposed respectively on the upper cover and on the box body. When the upper cover is closed on the box body, a lateral-moving bolt disposed on the male buckle can be inserted into the female buckle to be fixed. Thereby, there is a limitation between the upper cover and the box body so that the upper cover is not opened. However, the operation of such buckle is inconvenient, because the lateral-moving bolt of the male buckle is often protruding, and consequently the bolt must draw back so that the male buckle and the female buckle can face each other, resulting in inconvenience in operation.
Another buckle includes a buckling member disposed on the upper cover, and a wedging member disposed on the box body. A buckling plate disposed on the buckling member can be buckled in a wedging groove disposed on the wedging member by swinging. The buckling plate of the buckle can be elastically and automatically opened by spring, thus the buckling plate can be elastically opened when the upper cover is opened. Therefore, when the upper cover is closed on the box body, a user only needs to press the buckling plate and then the buckling plate and the wedging member can be linked up to provide a locking effect. However, the buckling member must be disposed on a base seat with similar size to the buckling member. By linking up a locking groove provided by the base seat and an inserted plate in the buckle, the buckling member and the wedging member can be linked up effectively, and the buckle can be disposed on the upper cover effectively. Thus, the overall size of the buckle is relatively large and the cost is relatively high.

SUMMARY OF THE INVENTION

The buckle with buckling function disclosed in the related art has a shortcoming in that the large base seat is needed to be disposed on the upper cover. Therefore, the present invention provides an innovative buckle structure for solving the shortcoming in the related art.
One object of the present invention is to provide a buckle structure with a small size. More particularly, the buckle structure disclosed in the present invention includes a wedging member disposed on a box body; a limiter provided with a limiting groove and disposed on an upper cover; a pivot seat disposed on the upper cover and a control member pivotally connected to the pivot seat; an elastically movable button disposed on the control member; a limiting inserted plate formed on a lateral side of the button to be corresponding to the limiting groove on the limiter; and a buckling plate pivotally connected with the control member and formed with a buckling edge on a bottom edge thereof. When said upper cover is closed on said box body, the buckling edge of said buckling plate is buckled in the wedging groove of said wedging member, and said limiting inserted plate is inserted into said limiting groove of said limiter; and when pressing the button of the control member, the limiting inserted plate separates from the limiting groove, and the control member and the buckling plate swing elastically to separate the buckling plate and the wedging member.
Thereby, in the present invention, there is no large base seat needed to link up the buckle and the box. Thus, the size is small and the cost is lowered for manufacturing.
Features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIG. 1. A box 10, a box body 12 and an upper cover 14 are disclosed in FIG. 1. The upper cover 14 can be closed on the box body 12, and at least one buckle 20 is disposed on a lateral side of the box 10 for providing a buckling effect to limit the upper cover 14 and the box body 12 to move relatively. That is to say, the upper cover 14 will not be opened. The above-mentioned box 10 can be a leather suitcase, a traveling case, a briefcase and so on.
Please refer to FIG. 2. The buckle 20 includes a wedging member 22 and a buckling member 24. The buckling member 24 can be buckled with the wedging member 22 to be linked up.
Please refer to FIG. 3. The wedging member 22 is a plate, and a concave wedging groove 26 is disposed thereon. As shown in FIG. 1, the wedging member 22 can be disposed on the box body 12.
Please refer to FIG. 3 again. The buckling member 24 includes a limiter 28 with two connecting posts 32 on one side and a limiting groove 34 on another side thereof. The connecting posts 32 have a hook structure, and thus the locating can be done when the connecting posts 32 are inserted into inserting holes 15 opened on the upper cover 14. A screw 36 can be further provided to fix the limiter 28 on the upper cover 14 firmly.
The buckle 24 includes a pivot seat 38. The pivot seat 38 is connected with the upper cover 14 by using a screw 42 to be fixed on locking holes 16 disposed on the upper cover 14. A pair of pivotal axes 44 are disposed separately on two ends of the pivot seat 38. A twisting spring 46 is provided on the pivot seat 38.
Please refer to FIG. 3 and FIG. 4. The buckle 24 includes a control member 48 connected to the pivotal axis 44 of the pivot seat 38. One end of the twisting spring 46 is against the control member 48. Please refer to FIG. 4 and FIG. 5. A button 52 is disposed on the control member 48. Two foot posts 54 are formed below the button 52. A pair of springs 56 are disposed separately on each of the foot posts 54 so that the button 52 can move elastically. Two limiting inserted plates 58 are formed on a lateral side of the button 52. A locking groove 62 is disposed on the button 52 and includes a first groove path 64 and a second groove path 66. The height of the first groove path 64 is smaller and that of the second groove path 66 is larger. The two groove paths 64 and 66 are communicated with each other. The top edge of the first groove path 64 is defined as a blocking edge 68.
It should be noted that the limiting inserted plates 58 formed on the lateral side of the button 52 are used for aligning with the limiting groove 34 of the limiter 28. In addition, twisting springs 72 are disposed on the control member 48 and corresponding to two lateral sides of the button 52.
Please refer to FIG. 3 and FIG. 4 again. The buckle 24 further includes a buckling plate 74 connected with the control member 48. One end of the twisting spring 72 of the control member 48 is against the buckling plate 74. A buckling edge 76 is formed on the bottom edge of the buckling plate 74. Please refer to FIG. 4 and FIG. 6. A movable plate 78 is disposed on the back of the buckling plate 74, and a locking shaft 82 is protruded on the movable plate 78. The locking shaft 82 passes through the button 52 and is corresponding to the locking groove 62. Please refer to FIG. 3 and FIG. 6, a pushing shaft 84 is protruded on another side of the movable plate 78 and passes through the buckling plate 74 for pushing the movable plate 78.
Structure and connection of each part in the present invention are mentioned above. Please refer to FIG. 7, the buckle 20 provides a locking function, that is, the buckling edge 76 of the buckling plate 74 is buckled in the wedging groove 26 of the wedging member 22, the limiting inserted plate 58 is inserted in the limiting groove 34 of the limiter 28, and the locking shaft 82 is corresponding below the blocking edge 68. Thereby, the button 52 presses down to make the blocking edge 68 against the locking shaft 82, and thus the limiting inserted plate 58 can not be separated from the limiting groove 34 and the buckling plate 74 will be not elastically opened by itself.
Please refer to FIG. 8. When the locking shaft 82 is pushed and is not against the blocking edge 68, the button 52 can be pressed down to separate the limiting inserted plate 58 from the limiting groove 34. Then, the buckling plate 74 and the control member 48 can be elastically open due to the elastic biased effect of the twisting spring 72 and the unlocking is done.
The assembly disclosed above in the present invention does not need a base seat of large size, and a simple limiter and a pivot seat are replaced instead. The size of buckle is reduced and the cost is lowered. The limiter can be connected with the upper cover by buckling, thus the assembly process is more convenient.
