Abstract

A variably-sized strap lock includes a strap and a lock body. The strap consists of a free end portion, a hinge portion and a lock portion. A variably-sized loop is formed by inserting the strap into the lock body and pulling the strap through the lock body to remove excess slack. The lock body engages either a series of teeth or a pair of chain-like members located on the strap and prevents withdrawal without disengagement by the user. A pair of hinges or the pair of chain-like members of the strap allow the hinge portion of the strap to lie flush against the lock body portion of the strap thus allowing the strap lock to be tightly secured onto an object to prevent rattling or inadvertent disengagement.

Claims

1. A strap lock comprising:

a strap having a free end portion, a hinge portion, and a lock portion;

a lock body, attached to said lock portion, having a strap receiving aperture;

wherein when said strap is passed through said strap receiving aperture, said lock body engages said strap to lock said strap within said lock body;

wherein said lock portion has a lock end and a hinged end;

wherein said hinge portion has a first hinged end, movably attached to said hinged end of said lock portion, and a second hinged end;

wherein said free end portion has a free end and a hinged end movably attached to said second hinged end of said hinge portion;

wherein said strap further comprises at least one securing member extending from said free end of said free end portion to at least said first hinted end of said hinge portion;

wherein when said strap is passed through said strap receiving aperture, said lock body engages said at least one securing member to lock said strap within said lock body; and

wherein said free end portion is made of a polymer and extends from said free end of said free end portion to said hinged end of said free end portion.

2. A strap lock comprising:

a strap having a free end portion, a hinge portion, and a lock portion;

a lock body, attached to said lock portion, having a strap receiving aperture;

wherein when said strap is passed through said strap receiving aperture, said lock body engages said strap to lock said strap within said lock body;

wherein said lock portion has a lock end and a hinged end;

wherein said hinge portion has a first hinged end, movably attached to said hinged end of said lock portion, and a second hinged end;

wherein said free end portion has a free end and a hinged end movably attached to said second hinged end of said hinge portion;

wherein said strap further comprises two securing members extending from said free end of said free end portion to at least said first hinged end of said hinge portion;

wherein when said strap is passed through said strap receiving aperture, said lock body engages said securing members to lock said strap within said lock body;

wherein said strap has two lateral edges;

wherein each of said two securing members is located at said lateral edges; and

wherein said free end portion comprises a strap body made of a plastic material, interposed between said two securing members, and extends from said free end of said free end portion to said hinged end of said free end portion.

3. A strap lock comprising:

an elongate flexible strap comprising a plastic material, said flexible strap having a free end and a hinged end;

a hinge plate having a first end hinged to said hinged end of said flexible strap and a second end; and

a lock portion having a hinged end hinged to said second end of said hinge plate, a strap receiving aperture extending through said lock portion for receiving said flexible strap therein so that said flexible strap can be inserted into said strap receiving aperture and through said lock portion so as to be adjustably positioned in said strap receiving aperture, and a lock positioned on said lock portion adjacent to said strap receiving aperture for locking said flexible strap in place upon insertion of said flexible strap into said strap aperture.

4. The strap lock of claim 3, wherein said hinge plate has a length between said first and second ends approximately the same as a length of said lock portion between said hinged end of said lock portion and said strap receiving aperture.

5. The strap lock of claim 3, wherein a reinforcing material is disposed within said flexible strap.

6. A strap lock comprising:

an elongate flexible strap comprising a plastic material, said flexible strap having a free end and a hinged end;

a hinge portion having a first end hinged to said hinged end of said flexible strap and a second end;

a lock portion having a hinged end hinged to said second end of said hinge portion, a strap receiving aperture extending through said lock portion for receiving said flexible strap therein so that said flexible strap can be inserted into said strap receiving aperture and through said lock portion so as to be adjustably positioned in said strap receiving aperture, and a lock positioned on said lock portion adjacent to said strap receiving aperture for locking said flexible strap in place upon insertion of said flexible strap into said strap receiving aperture.

7. The strap lock of claim 6, wherein said plastic material comprises Kevlar.

8. The strap lock of claim 6, wherein said hinge position has a length between said first and second ends approximately the same as a length of said lock portion between said hinged end of said lock portion and said strap receiving aperture.

9. The strap lock of claim 6, wherein a reinforcing material is disposed within said flexible strap.
