Abstract

Claims (70)

1. A drawer slide assembly for releasable engagement of a drawer to a cabinet comprising:

a cabinet rail telescopically engaged with an intermediate rail and configured to be attached to the cabinet;

a drawer rail telescopically engaged with the intermediate rail and configured to be attached to the drawer;

a bearing cage slidingly engaged between the intermediate rail and the drawer rail;

a cage hold device attached to the intermediate rail;

wherein upon removal of the drawer rail from engagement with the intermediate rail, the cage hold device releasably engages the bearing cage and holds the bearing cage at a forward position relative to the intermediate rail;

wherein the cage hold device further comprises:

a mounting curve;

a body having a mounting bar extending between a set of edges, wherein the mounting bar and the mounting curve are sized and shaped to be engaged in a mounting hole of the intermediate rail; and,

a flexible clip extending from the body and releasably engaged with the bearing cage.

2. The drawer slide assembly of claim 1 , wherein the cage hold device further comprises:

the body fixedly engaged with the intermediate rail;

a block extending from the body towards the drawer rail;

wherein the drawer rail further comprises:

a flexible trigger pivotally attached to the drawer rail and abutting the block; and,

whereby pulling the flexible trigger allows the flexible trigger to bypass the block.

3. The drawer slide assembly of claim 1 , further comprising:

a flexible trigger pivotally mounted to the drawer rail and releasably engaged with the cage hold device.

4. The drawer slide assembly of claim 1 , further comprising:

an end block attached to the cabinet rail and releasably engaged with the drawer rail.

5. The drawer slide assembly of claim 1 , further comprising:

a set of bearing runners, containing a set of ball bearings, slidingly engaged between the cabinet rail and the intermediate rail, and,

inner grooves, formed at curved edges of the intermediate rail, slidingly engaged with the set of ball bearings.

6. The drawer slide assembly of claim 1 , further comprising:

a set of stop tabs extending from the intermediate rail towards the cabinet rail;

a set of tabs extending from the cabinet rail; and,

a set of bearing runners slidingly engaged between the cabinet rail and the intermediate rail and abutting the set of stop tabs and the set of tabs.

7. The drawer slide assembly of claim 1 , further comprising:

a set of tabs extending from the intermediate rail; and,

wherein the bearing cage is slidable along the intermediate rail between the set of tabs and the cage hold device.

8. The drawer slide assembly of claim 1 , further comprising:

a set of pinch arms extending from the drawer rail; and,

an end block attached to the cabinet rail and releasably engaged with the set of pinch arms.

9. A method for positioning a bearing cage in a forward position of a drawer slide assembly comprising:

providing a drawer slide assembly comprising a cabinet rail, a telescopic intermediate rail, and a telescopic drawer rail;

providing a bearing cage slidingly engaged between the intermediate rail and the drawer rail;

providing a cage hold device fixedly attached to the intermediate rail;

providing a trigger pivotally attached to the drawer rail;

moving the drawer rail in an opening direction;

moving the intermediate rail in an opening direction;

abutting the cage hold device with the trigger;

flexing the trigger to bypass the cage hold device;

pulling the bearing cage towards the cage hold device with the drawer rail;

releasably engaging the bearing cage with the cage hold device;

disengaging the drawer rail from the bearing cage;

wherein the step of releasably engaging the bearing cage with the cage hold device further comprises:

providing a mounting curve;

providing a flexible clip extending from the cage hold device and a set of holes in the bearing cage;

engaging the mounting curve with a curved forward edge of the intermediate rail; and,

engaging the flexible clip with a forward most hole of the set of holes.

10. The method for positioning a bearing cage of claim 9 , wherein the step of releasably engaging the bearing cage with the cage hold device further comprises:

providing a protrusion extending from the flexible clip and a notch in the flexible clip disposed opposite of the protrusion;

flexing the flexible clip at the notch; and,

engaging the protrusion with the forward most hole of the set of holes.

11. The method for positioning a bearing cage of claim 9 , further comprising:

reengaging the drawer rail with the bearing cage;

moving the intermediate rail in a closing direction;

moving the drawer rail in the closing direction;

abutting the cage hold device with the trigger; and,

flexing the trigger to bypass the cage hold device.

12. The method for positioning a bearing cage of claim 9 , wherein the step of abutting the cage hold device with the trigger further comprises:

providing a block extending from the cage hold device; and,

abutting the block with the trigger.

13. The method for positioning a bearing cage of claim 9 , wherein the step of flexing the trigger to bypass the cage hold device further comprises:

providing the trigger includes providing a flexible arm disposed from a release arm;

moving the release arm; and,

bending the flexible arm.

14. The method for positioning a bearing cage of claim 9 , wherein the step of flexing the trigger to bypass the cage hold device further comprises:

providing a catch extending from the release arm engaged with a block extending from the cage hold device; and,

disengaging the catch from the block.
