Abstract

An undermount drawer slide mounting clip releasably attaches a drawer to a drawer rail assembly mounted in a cabinet carcass. The apparatus is capable of effecting positional adjustments of the drawer in three directions without removing the drawer from the cabinet carcass. The apparatus is comprised of a body slidingly engaged with a bonnet. A trigger pivotally connected between the body and the bonnet. A spring loaded catch slidable within the bonnet and acted on by the trigger to releasably attach the apparatus to a drawer rail assembly. A threaded spindle rotates within the base and adjusts the horizontal position of the drawer. A ramp adjustably connected to the base adjusts the vertical position of the drawer. A plunger extends from a housing connected to the body to adjacent the drawer rail assembly and adjusts the depth of the drawer.

Claims

1. A drawer slide clip mounting apparatus for releasably connecting a drawer to a drawer slide assembly mounted in a cabinet carcass, comprising:

a base configured to be mounted to the drawer;

a bonnet slidingly connected to the base;

,

a releasable locking means, operatively connected to the rack positioner, for controlling the sliding connection.

3. The drawer slide clip mounting apparatus of claim 1 wherein the wherein the rack positioner further comprises a set of rack teeth and wherein the releasable locking means further comprises:

a spring loaded release button rotationally fixed within and extending out of the bonnet;

the spring loaded release button further comprising a set of engagement teeth;

a pinion collar adjacent the release button and configured to selectively engage the engagement teeth;

the pinion collar further comprising a set of pinion teeth engaged with the rack teeth; and

,

whereby compressing the spring loaded release button disengages the engagement teeth from the pinion collar.

4. The drawer slide clip mounting apparatus of claim 3 wherein the engagement teeth further comprise a graduated tooth attack angle.

5. The drawer slide clip mounting apparatus of claim 3 wherein the engagement teeth further comprise at least one resilient pawl arm;

and

the pinion collar further comprises a set of ratchet teeth engaged with the at least one resilient pawl arm.

6. The drawer slide clip mounting apparatus of claim 5 wherein the pinion collar further comprises a first set of lock teeth;

a locking ring, having a first set of positioning threads and a second set of lock teeth constrained to vertical movement by the bonnet;

a lock lever, having a second set of positioning threads engaged with the first set of positioning threads, constrained to rotational movement by the locking ring;

whereby rotation of the lock lever in a first direction causes engagement of the first set of lock teeth and the second set of lock teeth; and

,

whereby rotation of the lock lever in a second direction causes disengagement of the first set of lock teeth from the second set of lock teeth.

7. The drawer slide clip mounting apparatus of claim 1 further comprising:

a housing mounted to the base;

an adjustable plunger slidingly attached to the housing;

wherein the apparatus adjusts a depth position of the drawer relative to the cabinet carcass when the plunger is repositioned relative to the housing.

8. The drawer slide clip mounting apparatus of claim 7 wherein the adjustable plunger further comprises:

a carriage fixed to the base;

a plunger having a threaded guide arm;

a thumbscrew threaded into the carriage and the threaded guide arm; and

,

wherein rotation of the thumbscrew in a first direction advances the plunger with respect to the carriage and rotation of the thumbscrew in a second direction retracts the plunger with respect to the carriage.

9. The drawer slide clip mounting apparatus of claim 1 wherein:

the base further comprises a threaded spindle;

the bonnet further comprises a first flange and a second flange adjacent the threaded spindle; and

,

a knob, threaded onto the spindle, between the first flange and the second flange;

whereby rotation of the knob clockwise moves the bonnet in a first direction with respect to the base and rotation of the knob counter-clockwise moves the bonnet in a second direction with respect to the base.

10. The drawer slide clip mounting apparatus of claim 1 wherein the bonnet further comprises a first set of serrated teeth and further comprising:

a ramp, constrained to sliding movement by the bonnet;

the ramp further comprising a ramp extension having a second set of serrated teeth engaged with the first set of serrated teeth; and

,

whereby movement of the extension advances the ramp under the drawer slide to effect a vertical adjustment of the drawer.

2. The drawer slide clip mounting apparatus of claim further comprising:

a trigger lever pivotally connected to the rack positioner;

a catch dog slidingly connected to the rack positioner;

a spring bias between the catch dog and the rack positioner; and

,

a transfer plate connected to the catch dog and pivotally connected to the trigger lever;

whereby compression of the trigger lever effects a retraction of the catch dog and release of the trigger lever effects an extension of the catch dog.

11. A drawer slide clip mounting apparatus for releasably connecting a drawer to a drawer slide assembly mounted in a cabinet carcass, comprising:

a base, adapted to be attached to the drawer;

a bonnet, slidingly attached to the base;

a depth adjustment means, attached to the base, for adjusting a depth distance, between the drawer and the drawer slide assembly;

a vertical adjustment means, attached to the bonnet, for adjusting a vertical distance between the drawer and the drawer slide assembly; and

a lateral adjustment means, attached to the base, for adjusting a horizontal distance between the drawer and the drawer slide assembly.

12. The drawer slide clip mounting apparatus of claim 11 further comprising:

a release mechanism, attached to the bonnet, for releasably coupling the apparatus to the drawer slide assembly.

13. The drawer slide clip mounting apparatus of claim 12 wherein the release mechanism further comprises:

a rack positioner, constrained to slide in a depth direction by the bonnet, and further comprising a set of rack teeth;

a releasable catch assembly, attached to the rack positioner and adapted to engage the drawer slide;

a release button, constrained to vertical movement by the bonnet, and further comprising a set of engagement teeth;

a pinion collar, constrained to rotational movement about the release button, by the bonnet, and further comprising a set of pinion teeth and a first set of lock teeth;

the pinion teeth engaging the rack teeth; and

,

whereby the engagement teeth engaging the first set of lock teeth when the release button is in a released position, thereby inhibiting movement of the rack positioner; and

,

whereby the engagement teeth disengaging the first set of lock teeth when the release button is in a compressed position, thereby permitting movement of the rack positioner.

14. The drawer slide clip mounting apparatus of claim 13 wherein the pinion collar further comprises a second set of lock teeth:

a lock lever, positioned in the bonnet and constrained to rotational movement, and further comprising a first set of riser threads;

a locking ring, having a second set of riser threads in contact with the first set of riser threads, and constrained to vertical movement by the bonnet;

whereby rotation of the locking ring alternatively engages and disengages the first set of lock teeth from the second set of lock teeth.

15. The drawer slide clip mounting apparatus of claim 14 whereby rotation of the locking ring is inhibited by a set of positioning steps on the bonnet.

16. The drawer slide clip mounting apparatus of claim 13 wherein the lock teeth are serrated;

and,

the engagement teeth further comprise at least one triangular catch operatively disposed on a resilient pawl arm; and

,

whereby inhibiting movement of the rack positioner further comprises inhibiting movement in a proximal direction and permitting movement in a distal direction.

17. The drawer slide clip mounting apparatus of claim 13 wherein the lock teeth are triangular and the engagement teeth are graduated.

18. The drawer slide clip mounting apparatus of claim 11 wherein the depth adjustment means further comprises:
