Description
BACKGROUND OF THE INVENTION

[0001] The present invention relates to a belt lock and, more specifically, to such a belt lock, which fits belts of different thickness.

[0002] A variety of belt locks have been disclosed for use in shoes, safety belts, binding devices, and etc. FIG. 5 shows a belt lock for this purpose. This structure of belt lock comprises a base member B, and a locking member A. The base member B comprises a shaft B1, and an engagement portion B2 disposed in parallel to the shaft B1. The locking member A comprises a coupling hole Al pivoted to the shaft B1 of the base member B, and an engagement portion A2 adapted for working with the engagement portion B2 of the base member B to hold down the inserted belt member. This structure of belt lock is suitable for locking a belt member of a particular thickness. For locking a different thickness of belt member, a different specification of the base member B and the locking member A must be used.

SUMMARY OF THE INVENTION

[0003] The present invention has been accomplished to provide a belt lock, which eliminates the aforesaid problem. It is the main object of the present invention to provide a belt lock, which fits belt members of different thickness. According to the present invention, the belt lock comprises a casing, and a locking unit pivoted to the casing and adapted to lock the belt member being inserted through the casing. The locking unit comprises a handle pivoted to the casing, and a swivel pressure block pivoted to the handle and driven by the handle to hold down the inserted belt member. The swivel pressure block has a serrated engagement portion extended along a smoothly arched peripheral wall thereof for engaging any of a variety of belt members of different thickness.

BRIEF DESCRIPTION OF THE DRAWINGS

[0004]FIG. 1 is an exploded view of a belt lock according to the present invention.

[0005]FIG. 2 is an elevational assembly view of the belt lock according to the present invention.

[0006]FIG. 3 is a schematic drawing showing the use of the present invention.

[0007]FIG. 4 is a sectional view showing the locking unit turned to the locking position.

[0008]FIG. 5 is an exploded view of a belt lock according to the prior art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0009] Referring to FIGS. 1 and 2, a belt lock in accordance with the present invention is comprised of a casing 1, and a locking unit 2 2. The casing 1 comprises a plurality of transverse belt slots 14 arranged in parallel near the rear side thereof, a serrated engagement portion 12 transversely disposed near the front side thereof, a bearing portion 13 transversely disposed adjacent to the serrated engagement portion 12, two parallel side walls 11 respectively perpendicularly extended from two opposite lateral sides thereof, and two pivot holes 111 respectively provided at the parallel side walls 11 near the front side. The locking unit 2 comprises a handle 21, and a swivel pressure block 22. The handle 21 comprises a smoothly arched inwardly curved front notch 213, and two barrels 211 aligned at two sides of the front notch 213. The barrels 211 each have a serrated engagement portion 212 disposed at a bottom side. The swivel pressure block 22 is a sector-like block comprising two pivot rods 222 aligned at two sides, and a serrated engagement portion 221 disposed at the bottom side wall thereof along the smoothly arched periphery. The barrels 211 of the handle 21 are respectively coupled to the pivot holes 111 of the casing 1. The pivot rods 222 of the swivel pressure block 22 are respectively pivoted to the barrels 211 of the handle 21.

[0010] Referring to FIGS. 3 and 4, a belt 3 is fastened with its one end to the belt slots 14 and inserted with its other end through the gap between the casing 1 and the locking unit 2. When the user turns the handle 21 downwards from the vertical position toward the casing 1, the periphery of the front notch 213 is moved to the smoothly arched periphery of the swivel pressure block 22. Continuously turning the handle 21 downwards causes the swivel pressure block 22 to be rotated clockwise, thereby causing the serrated engagement portion 221 of the swivel pressure block 22 to be pressed on the belt 3 against the bearing portion 13 of the casing 1 and a part of the swivel pressure block 22 pressed on the belt 3 against the serrated engagement portion 12 of the casing 1, and therefore the belt 3 is locked.

[0011] Because the serrated engagement portion 221 extends along the smoothly arched periphery of the swivel pressure block 22, it fits different thickness of the belt 3. Further, because the pivot rods 222 can be rotated with the swivel pressure block 22 in the barrels 211 of the handle 21, the angle of engagement of the swivel pressure block 22 with the belt 3 can be adjusted subject to the thickness of the belt 3.

[0012] While only one embodiment of the present invention has been described, it will be understood that various modifications and changes could be made thereunto without departing from the spirit and scope of the invention disclosed.
