ABSTRACT:
FIELD OF THE INVENTION
This invention relates to fasteners in general, and more particularly to those fasteners characterized by using barbs to secure an object in place.
BACKGROUND OF THE INVENTION
A large number of fasteners have been used in the past for securing one object on another object, at least partially by means of barbs.
Examples include U.S. Pat. Nos. 2,322,656; 2,329,688 (the barbs referred to as locking tongues

; see column 2, lines 14-22), U.S. Pat. Nos. 2,607,971; 2,825,948; 3,525,129; 3,525,129; 3,673,643; 4,683,622; 5,314,280; 5,422,789; 5,373,611; 5,542,158 (the barbs referred to as wedge-like extensions; see column 3, lines 10-17), U.S. Pat. No. 5,887,319; and Canadian Patent 496,700, among a plethora of other references.
SUMMARY OF THE INVENTION
The instant invention is directed to fasteners characterized by the use of barbs to secure an object in place. More particularly, the instant invention pertains a fastener having a fastening region within which at least a part of a primary object can be inserted, the fastener comprising a first structural side adjacent to the fastening region, the first structural side comprising a first bent barb extending from the first structural side into the fastening region, the first bent barb having a first back portion adjacent to the first structural side and a first front portion adjacent to the primary object, when the primary object has been inserted into the fastening region, the first front portion having a first angle with respect to the primary object which is different than a respective second angle that the first front portion would have with respect to the primary object if the first barb were straight and not bent, the fastening region having an insertion end through which the primary object is to be inserted, the first back portion of the first bent barb being closer to the insertion point than the first front portion of the first bent barb. For best results, the first angle is greater than the second angle.
With this configuration, the primary object can also be removed after it has been inserted, without manipulation of the fastener,
The fastener may be inserted into a slot of a secondary object, or otherwise secured or attached on a secondary object, so that the two objects are finally secured or attached to each other through the fastener.
It is preferable that the fastener further comprises a second structural side opposite the first structural side, wherein the second structural side comprises a second barb. The second barb may be a straight barb.
It is preferable that the second bent barb extends from the second structural side into the fastening region, the second bent barb having a second back portion adjacent to the second structural side and a second front portion adjacent to the primary object, when the primary object has been inserted into the fastening region, the second front portion having a third angle with respect to the primary object which is different than a respective fourth angle that the second front portion would have with respect to the primary object if the second barb were straight and not bent, the second back portion of the second bent barb being closer to the insertion point than the second front portion of the second bent barb. For best results, the third angle is greater than the fourth angle.
The present invention also relates to a vehicle which comprises a fastener as described above.
