## Abstract

The present disclosure relates generally to fixturing devices and more specifically to a pivoting fixture device configured to locate and lock a check feature in a precise location.

## Claims

### Claim 1

A pivoting fixture unit comprising:
a modular base having a channel portion disposed between two sidewalls;
a platform being disposed between the two sidewalls and coupled to the base by a pivot pin;
a net pad attached to a base portion of the channel; and
a stop key configured to rotationally secure the platform in a locating position, wherein the stop key applies consistent pressure to the platform in the locating position of the platform.

### Claim 2 (depends on 1)

The pivoting fixture unit of claim 1, wherein the stop key engages the base and extends through a locking aperture in the platform.

### Claim 3 (depends on 2)

The pivoting fixture unit of claim 2, wherein the stop key comprises a spring washer disposed proximal to a shaft portion.

### Claim 4 (depends on 2)

The pivoting fixture unit of claim 2, wherein the stop key comprises negative flats configured to rotationally engage a pair of recessed steps disposed in the platform.

### Claim 5 (depends on 1)

The pivoting fixture unit of claim 1, further comprising a plate attached to the modular base and abutting each sidewall.

### Claim 6 (depends on 4)

The pivoting fixture unit of claim 4, wherein the plate comprises a mounting plate.

### Claim 7 (depends on 1)

The pivoting fixture unit of claim 1, further comprising a plurality of mounting holes being accessible in the locating position.

### Claim 8 (depends on 1)

The pivoting fixture unit of claim 1, wherein the platform extends along the channel portion and forms a recessed gap on each side extending between a plurality of contact surfaces between the sidewalls and the platform.

### Claim 9 (depends on 1)

The pivoting fixture unit of claim 1, further comprising a spring disposed around the pivot pin and engaging the platform and the base to control rotation of the platform.

### Claim 10

A locking mechanism comprising:
a platform being pivotally attached to a body;
a net pad attached to the body and configured to abut the platform in a locating position; and
a stop key configured to rotationally secure the platform in a locating position, wherein the net pad is presses against the stop key to retain the platform in a locating position.

### Claim 11 (depends on 10)

The pivoting fixture unit of claim 10, wherein the stop key engages the base and extends through a locking aperture in the platform.

### Claim 12 (depends on 11)

The pivoting fixture unit of claim 11, wherein the stop key comprises a spring washer disposed proximal to a shaft portion.

### Claim 13 (depends on 11)

The pivoting fixture unit of claim 11, wherein the stop key comprises negative flats configured to rotationally engage a pair of recessed steps disposed in the platform.

### Claim 14 (depends on 11)

The pivoting fixture unit of claim 11, wherein the locking aperture extends through the platform proximate to a longitudinal axis of the platform.

### Claim 15 (depends on 10)

The pivoting fixture unit of claim 10, wherein the stop key engages a central portion of the platform.

### Claim 16 (depends on 15)

The pivoting fixture unit of claim 15, wherein the central portion of the platform is defined as at least ⅓ of the width of the platform.

### Claim 17 (depends on 10)

The locking mechanism of claim 10, wherein the stop key comprises a tapered engaging surface being configured to engage the platform with increasing pressure along a rotational path until reaching a locked position.

### Claim 18 (depends on 10)

The locking mechanism of claim 10, wherein the stop key is configured to lock and unlock through a single hand operation.

### Claim 19 (depends on 10)

The locking mechanism of claim 10, wherein the stop key applies consistent pressure in the locating position independent of the rotational torque applied to rotate the stop key.

### Claim 20

A pivoting fixture unit comprising:
a modular base having a channel portion disposed between two sidewalls;
a platform being disposed between the two sidewalls and coupled to the base by a pivot pin;
a recessed gap forming a gap between the platform and the sidewalls adjacent to a plurality of contact surfaces between the platform and the sidewalls;
a net pad attached to a base portion of the channel; and
an engaging pin configured to rotationally secure the platform in a locating position, wherein the net pad is compresses against the engaging pin.
