## Abstract

A bollard assembly includes a post including at least one locking flange or pin and a cooperating base defining a post receiver. The base includes at least one interior wall including at least one cooperating locking groove dimensioned and configured to receive an end of the at least one locking flange or pin. The at least one cooperating locking groove includes at least one portion defining a substantially vertical pathway and at least one intersecting portion defining a substantially horizontal pathway. The at least one cooperating locking groove may defined by a top portion and a bottom portion each defining a substantially vertical pathway, and an intersecting intermediate portion defining a plane oriented substantially perpendicularly to the top portion and the bottom portion.

## Claims

### Claim 1

A bollard assembly, comprising:
a post including a plurality of locking flanges or pins; and
a cooperating base defined by at least:
a top lip or flange defining a mating surface adapted to support the weight of the post; and
at least one interior wall defining a post receiver having a plurality of cooperating locking grooves defined therein, wherein each of the plurality of cooperating locking grooves is defined by a top portion and a bottom portion each defining a substantially vertical pathway, and an intersecting intermediate portion defining a plane oriented substantially perpendicularly to the top portion and the bottom portion;
wherein the plurality of locking flanges or pins are disposed to remove accumulated debris from an interior of the plurality of cooperating locking grooves on interlocking the post with or removing the post from the receiver.

### Claim 2 (depends on 1)

The assembly of claim 1, further including a base cover or plug.

### Claim 3 (depends on 1)

The assembly of claim 1, wherein a top portion of the post includes a through-bore for receiving a lever therethrough.

### Claim 4 (depends on 1)

The assembly of claim 1, wherein the cooperating base includes at least one ground anchor.

### Claim 5

A bollard system, comprising:
a plurality of posts each including a plurality of locking flanges or pins; and
a plurality of cooperating bases each defined by at least:
a top lip or flange defining a mating surface adapted to support the weight of the post; and
at least one interior wall defining a post receiver having a plurality of cooperating locking grooves defined therein, wherein each of the plurality of cooperating locking grooves is defined by a top portion and a bottom portion each defining a substantially vertical pathway, and an intersecting intermediate portion defining a plane oriented substantially perpendicularly to the top portion and the bottom portion.

### Claim 6 (depends on 5)

The assembly of claim 5, further including a base cover or plug.

### Claim 7 (depends on 5)

The assembly of claim 5, wherein a top portion of each post includes a through-bore for receiving a lever therethrough.

### Claim 8 (depends on 5)

The assembly of claim 5, further including a plurality of post top caps.

### Claim 9 (depends on 5)

The assembly of claim 5, wherein each cooperating base includes at least one ground anchor.

### Claim 10

A bollard assembly, comprising:
a post including a plurality of locking flanges or pins; and
a cooperating base defined by at least:
a top lip or flange defining a mating surface adapted to support the weight of the post; and
at least one interior wall defining a post receiver having a plurality of cooperating locking grooves defined in but not through said at least one interior wall, each of the plurality of cooperating locking grooves being disposed and configured to receive an end of a one of the plurality of locking flanges or pins.

### Claim 11 (depends on 10)

The assembly of claim 10, wherein each of the plurality of cooperating locking grooves is defined by a top portion and a bottom portion each defining a substantially vertical pathway, and an intersecting intermediate portion defining a plane oriented substantially perpendicularly to the top portion and the bottom portion.

### Claim 12 (depends on 10)

The assembly of claim 10, further including a base cover or plug.

### Claim 13 (depends on 10)

The assembly of claim 10, wherein a top portion of the post includes a through-bore for receiving a lever therethrough.

### Claim 14 (depends on 10)

The assembly of claim 10, wherein the cooperating base includes at least one ground anchor.
