## Abstract

An improved barrel bolt assembly and extensible gate comprising the same wherein the assembly includes a washer having at least one inward or outward projection annularly disposed about an internal periphery thereof, a fastener having a head portion and a shank portion extending therefrom, and a barrel having a head portion and a boss portion extending therefrom, wherein the boss portion is operative to receive the fastener shank portion and the barrel boss portion further includes at least one inward or outward projection annularly and complementarily disposed and formed with respect to the inner periphery of the washer, to receive and mate with the washer, whereby the washer and barrel interlock to prevent rotational movement with respect to each other.

## Claims

### Claim 1

An extensible gate assembly, comprising:
a shelving assembly disposed on a retail or warehouse floor, the shelving assembly having first and second posts defining an aisle there between;
a plurality of interconnected gate member pairs, each member pair comprising a first member and a second member separated by a corresponding primary washer wherein the first and second members are each operative to rotate transversely to one another about a corresponding common axis and corresponding common joint including the primary washer through a corresponding angle of rotation selected from a plurality of angles of rotation, during expansion of the gate between the first and second posts to block access to the aisle, and during retraction of the gate between the first and second posts to permit access to the aisle;
wherein at least one said corresponding common joint comprises a barrel bolt assembly, the barrel bolt assembly further comprising:
a secondary washer having at least one inward or outward projection annularly disposed about an internal periphery thereof;
a fastener having a head portion and a shank portion extending from the fastener head portion;
a barrel having a head portion and a boss portion extending from the barrel head portion, the boss portion operative to receive the fastener shank portion; and
wherein the barrel boss portion further comprises at least one inward or outward projection annularly and complementarily disposed and formed with respect to the inner periphery of the secondary washer, to receive and mate with the secondary washer, whereby the secondary washer and barrel interlock to prevent rotational movement with respect to each other to inhibit loss of joint tension or preload from relative rotational movement of the member pair about its corresponding angle of rotation during expansion and retraction of the gate, thus inhibiting fatigue and failure of the common joint and gate.
