Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a buckle device, and more particularly to a buckle device including a structure for allowing the strap to be easily and quickly adjusted relative to the buckle device and for allowing the strap to be easily and quickly attached onto the cargo or objects.

2. Description of the Prior Art

Typical buckle devices comprise a male member and a female member detachably coupled together, and each including an aperture formed therein for strapping or engaging with a belt and for detachably coupling or attaching the buckle devices onto a user or a cargo or objects.

For example, U.S. Pat. No. 6,237,826 to Gould, U.S. Pat. No. 6,363,590 to Lan, and U.S. Pat. No. 6,446,849 to Schleifer disclose three of the typical buckle devices each comprising a male member and a female member detachably fastened together, and the female member including a chamber for receiving the male member, and a belt or a strap coupled to the male member and the female member with frictional snubbing devices and for allowing the belt to be adjustably coupled or attached onto the user or the cargo or the objects.

However, the typical buckle devices include only an aperture formed therein for strapping or receiving the belt or the strap, but have no engaging means or device for engaging with the belt or the strap such that the belt or the strap may not be frictionally attached to the typical buckle devices and may not be adjusted relative to the buckle devices.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional belt buckle devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1-3, a buckle device in accordance with the present invention comprises a female member 10 including a chamber 11 formed therein and formed or defined by an upper wall 12 and two side walls 13, and including a notch or opening 14 formed in each of the side walls 13, and/or partially formed in the upper wall 12, and including a spring blade 15 extended into each of the openings 14 for being depressed by the user. A male member 20 includes two or more catches or tongues or tabs 21 extended therefrom for engaging into the chamber 11 of the female member 10 and for aligning with the openings 14 of the female member 10 and for detachably coupling the female member 10 and the male member 20 together.

A belt or strap 80 includes one end 81 coupled to the male member 20 for coupling or attaching onto the users or the cargo or the objects (not shown). The spring blade 15 of the female member 10 are aligned with the tabs 21 of the male member 20 (FIG. 1) for allowing the tabs 21 of the male member 20 to be depressed with the spring blade 15 of the female member 10 by the user for allowing the tabs 21 of the male member 20 to be detached or disengaged from the female member 10 when the spring blades 15 are depressed by the user. Alternatively, without the spring blades 15, the tabs 21 of the male member 20 may also be directly depressed by the user. The above-described structure is typical and will not be described in further details.

The buckle device in accordance with the present invention further comprises a pawl or pressing device 30 engaged into the chamber 11 of the female member 10, and the pressing device 30 includes one end or first end 31 rotatably or pivotally attached or secured or coupled to the one end or first end 16 of the female member 10 with a pivot axle 32, for example, the pressing device 30 includes a tubular member 33 formed or provided on the first end 31 for receiving or engaging with the pivot axle 32 and for pivotally attaching or coupling the pressing device 30 in the chamber 11 of the female member 10.
