ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention pertains to a web adjustment member for a two-piece buckle, which is slip-resistant and can be used in tight contours.
2. Description of the Prior Art
In the prior art, it is known to use a two-piece buckle to fasten together two lengths of webbing and to adjust the effective lengths of the webbing. However, typically the goal of providing simple adjustment of the effective lengths of the webbing, particularly adjustment by a single hand of the user, has conflicted with the goal of maintaining a fixed effective length after the adjustment has been made. Additionally, some buckles of the prior art have had difficulties in achieving the above goals when used in tight contours, particularly if the use in tight contours causes a rotation of an end portion of the buckle. An example of such a buckle is disclosed in U.S. Pat. No. 4,171,555 entitled “Buckle” and issued to Bakker et al. on Oct. 23, 1979.
Examples of somewhat similar prior art include U.S. Pat. No. 5,651,166 entitled “Method and Apparatus for Anti-Slip Webbing Adjustment” and issued on Jul. 29, 1997 to Lundstedt; U.S. Pat. No. 733,248 entitled “Buckle” and issued to Mitchell on Jul. 7, 1903; U.S. Pat. No. 165,333 entitled “Snap-Hook” and issued on Jul. 6, 1875 to Jackson; and U.S. Pat. No. Des. 328,044 entitled “Adjustable Strap Fastener” and issued on Jul. 21, 1992 to Murai.
OBJECTS AND SUMMARY OF THE INVENTION
It is therefore an object of this invention to provide a web adjustment member for a buckle which can be used to easily adjust the lengths of webbing.
It is therefore a further object of this invention to provide a web adjustment member for a buckle which maintains the adjustment of the lengths of webbing.
It is therefore a still further object of this invention to provide a web adjustment member for a buckle which can be used in tight contours, while maintaining the adjustment of the lengths of the webbing.
These and other objects are attained by providing a web adjustment member for a two-piece buckle, the two-piece buckle being of the type comprising a latch component and a body component, with the latch component detent engaging the body component in a fastened position. The web adjustment member is formed on the rear portion of the latch component and includes three lacing bars, two of the lacing bars are formed in close proximity to each other to form a pinch point while the third lacing bar is positioned so as to maintain the pinch point during any possible rotation or curvature of components of the buckle such as may occur during use in tight contours.
To tighten the buckle, the user pulls on the free end of the webbing which causes the bottom portion of the webbing to become taunt which in turn produces a pinch point at the bottom of the back bar and the free end of the webbing. Unlike many other buckles, this buckle cannot be loosened by rotating. When the rear component of the latch portion is rotated, the third lacing bar retains the pinch point between the bottom of the back bar and the free end of the webbing.
