## Abstract

A quick release mechanism for a pole mounted mirror has a base for receiving a pole. The base attaches to a mirror. The base carries a knob that when tightened, clamps the pole against the mirror.

## Claims

### Claim 1

A quick release device for the attachment of a vehicular mirror to a pole, comprising:
a mounting base for attachment to the mirror, the base having a collar providing threaded engagement with a rotating knob, the knob carrying a stub that moves within the collar;
the base having a notch for receiving the pole;
the stub being disposed to clamp the pole against the mirror;
wherein the knob carries a friction clamp and the collar has external ribs that cooperate with the clamp;
wherein the external ribs are formed on the exterior of the collar and cooperate with longitudinally arranged teeth formed on the interior of the clamp that releasably engage the external ribs of the collar, so that the engagement of the longitudinally arranged teeth with the external ribs sufficiently frictionally grips the knob to the mounting base to prevent the unscrewing of the knob from the mounting base.

### Claim 2 (depends on 1)

The device of claim 1, wherein:
the base has a flange with mounting openings for receiving mounting fasteners and the knob has a through opening that aligns with at least one of one or more mounting openings provided on the mounting base.

### Claim 3 (depends on 1)

The device of claim 1, wherein:
the stub carries a polymeric bumper.

### Claim 4 (depends on 1)

The device of claim 1, wherein:
the collar has longitudinal access channels that align with one or more mounting openings provided on the mounting base.

### Claim 5 (depends on 1)

The device of claim 1 wherein:
the knob has a web in which is formed a hole that receives a stub fastener, the stub fastener attaching the stub to the knob.

### Claim 6 (depends on 1)

The device of claim 1, wherein:
the collar has internal guide slots that cooperate with the stub.

### Claim 7 (depends on 1)

The device of claim 1, further comprising:
a coupling that attaches to the base, the coupling having a retainer;
the coupling and retainer adapted to engage a wall of a socket in the mirror;
a coupling fastener extending through a cap that retains a compression spring located between the cap and the retainer.

### Claim 8 (depends on 7)

The device of claim 7, wherein:
the coupling, the retainer and the wall of the socket are radiused.

### Claim 9 (depends on 1)

A mirror comprising the quick release device of claim 1.
