Abstract

A portable, flexible lock is disclosed with a cut-resistant strap formed of a durable and flexible outer portion and that defines a chamber for receiving a second durable, flexible inner portion therein. The inner portion floats freely side-to-side within the chamber thereby making the inner portion more difficult to cut. In a disclosed embodiment, the outer portion is formed of woven KEVLAR and the inner portion is a stainless steel cable. The lock may include a housing assembly that holds one end of the strap while a synching device, such as a pivoting cam or the like, detachably secures a portion of the opposite end of the strap thereto when the synching device in a locked position. A lock structure holds the synching device in its locked position. One or more tools may be detachably secured to the housing assembly.

Claims

1. A lock having:

a housing;

an elongate flexible strap having a first end, an opposite second end, a first side and an opposite second side;

a flexible, cut-resistant outer portion defining a chamber therein, and

a cut-resistant inner portion disposed in the chamber, the inner portion movable within the chamber between the first side and opposite second sides of the strap; and

,

a locking structure having an open position and a locked position operably secured to the housing and the elongate flexible strap to hold the strap in place relative to the housing to define a lock portion of the strap in the locked position and release at least one of said first and said opposite second ends of the strap in said open position.

2. The lock of claim 1, wherein said outer portion comprises a first cut-resistant material and said inner portion is formed of a second cut-resistant material.

3. The lock of claim 1, wherein said outer portion comprises a high tensile strength polymer.

4. The lock of claim 1, wherein the outer portion comprises woven high tensile strength polymer.

5. The lock of claim 4, wherein the outer portion comprises KEVLAR.

6. The lock of claim 1, wherein the inner portion comprises formed of flexible metal.

7. The lock of claim 6, wherein the flexible metal comprises stainless steel.

8. The lock of claim 7, wherein the flexible metal comprises strands of stainless steel formed into a cable.

9. The lock of claim 1, wherein the inner portion is secured to the outer portion at the first end and the opposite second end of the flexible strap.

10. The lock of claim 1, wherein the housing includes tools detachably secured thereto.

11. The lock of claim 1, wherein the locking structure includes a synching structure pivotally secured to the housing and the housing includes a base portion for wedging a portion of the strap between the synching structure and the base portion when the locking structure is in the locked position.

12. The lock of claim 11, wherein the synching structure includes a cam pivotally secured to the housing, the cam having a strap engaging portion and a handle portion.

13. The lock of claim 12, wherein the housing has an upper surface and the handle portion does not extend above the upper surface of the housing in the locked position.

14. The lock of claim 12, wherein the locking structure includes a cylinder lock operably secured between the housing and the cam at the pivot.

15. The lock of claim 1, further including a flexible ring operably secured to the second end of the strap, the flexible ring sized to extend around the housing and strap coiled around the housing, thereby holding the coiled strap around the housing for storage.

16. The portable and flexible lock comprising:

a housing having a base portion, a first side, an opposite second side, a pivot extending between the first side and second side and slot for slidably receiving a strap therethrough;

the strap having a first end, an opposite second end, a first side and an opposite second side, the strap having a flexible cut-resistant outer portion defining a chamber and a cut-resistant inner portion disposed within the chamber, the inner portion movable between the first side and second side within the chamber;

the first end of the strap rigidly secured to the housing;

a cam having a strap engaging portion, a handle portion, and a pivot engaging portion pivotally secured to the housing at the pivot, the cam having an open position in which the strap engaging portion does not engage the strap when the second end of the strap is received through the slot and a locked position in which the strap engaging portion engages the strap when the second end of the strap is received through the slot so as to hold the strap within the housing; and

a locking device operably secured between the housing and cam so as to lock the cam in its locked position.

17. The lock of claim 16, wherein the outer portion of the strap comprises woven KEVLAR, and the inner portion of the strap comprises a stainless steel cable.

18. The lock of claim 16, further including tools detachable secured to the housing.

19. The lock of claim 16, wherein the housing has an upper surface and the handle of the cam does not extend above the upper surface of the housing when the cam is in the locked position.
