A rack for an appliance includes a main section having a support frame, and at least one arm coupled to the support frame. The arm is movable relative to the support frame between a first position and a second position. The rack further includes a release member operatively connected to the at least one arm, actuation of the release member causing the at least one arm to move from the first position to the second position. In one example, the rack includes pair of arms coupled to the support frame. In another example, actuation of the release member causes both of the arms to move to the second position.
1. A rack for an appliance, including:
a main section having a support frame, the support frame having a front bar, a rear bar, a first side bar, and a second side bar;
at least one arm coupled to the support frame and having an end configured to abut a respective downward facing projection on a wall of an appliance, the arm being movable relative to the support frame between a first position and a second position; and
a release member operatively connected to the at least one arm, actuation of the release member causing the at least one arm to move from the first position to the second position,
wherein the release member includes a first end portion and a second end portion, the first end portion being coupled to the first side bar and the second end portion being coupled to the second side bar, and
wherein the end of the at least one arm is an edge,
wherein the rack includes a pair of arms each movable relative to the support frame between a first position and a second position and each arm including a cam surface and wherein the release member includes a pair of link members, actuation of the release member engaging the link members within the respective cam surfaces causing the arms to move from the first position to the second position, and
wherein the main section further includes a pair of slides which includes a pair of limiting projections each adapted to capture one of the link members between the limiting projection and the cam surface.
2. The, rack of claim 1 , wherein the at least one arm is resiliently biased towards the first position.
3. The rack of claim 1 , wherein the at least one arm is configured for pivoting movement towards the first position for engagement with a stop portion of an appliance cavity for inhibiting removal of the main section therefrom.
4. The rack of claim 1 , wherein the release member includes a handle potion operatively coupled to both of the link members.
5. The rack of claim 1 , wherein the cam surface is convex.
6. The rack of claim 5 , wherein the each of the link members includes convex end portions configured to contact the corresponding convex cam surface of the arms.
7. The rack of claim 1 , wherein the release member is pivotally coupled to the main section.
8. The rack of claim 1 , wherein the rack further includes an auxiliary section having an auxiliary platform area, the auxiliary section being adapted to be slidably coupled to the main section to move between a retracted position and an extended position.
9. A rack for an appliance, including:
a main section having a support frame adapted to be supported by guide rails on sidewalls within an appliance;
a pair of arms coupled to the support frame and each movable relative to the support frame, each arm being configured to abut corresponding stop portions on the guide rail of said sidewalls for inhibiting removal of the main section from an appliance cavity; and
a release member operatively connected to both of the arms, actuation of the release member causing both of the arms to disengage from respective stop portions of said guide rails,
wherein the arms each include convex cam surfaces, and
wherein the release member includes a pair of link members having convex-shaped end portions configured to engage the convex cam surfaces,
wherein the stop portions each include a downward extending projection formed with a portion of one of the guided rails of said appliance, and
wherein the convex cam surfaces of each arm are configured to automatically move each arm away from a first position and toward second position, whereupon passage of the arms beyond a cam portion of each guide rail permits the arms to be resiliently biased back toward the first portion.
10. The rack of claim 9 , wherein each arm is pivotally coupled to the support frame for movement between a first position and a second position, both of the arms being resiliently biased towards the first position for engagement with respective projections, and
wherein each arm includes an end having an edge that contacts the respective projections.
11. The rack of claim 10 , wherein the edge of each end of each arm is substantially perpendicular to the corresponding stop portion of said guide rails.
12. The rack of claim 9 , wherein the rack further includes an auxiliary section having an auxiliary platform area, the auxiliary section being adapted to be slidably coupled to the main section to move between a retracted position and an extended position.
13. The rack of claim 9 , wherein the convex cam surfaces engage the convex link members in point-to-point contact across an entire range of movement.
14. The rack of claim 9 , wherein the arms are resiliently biased away from the main section and towards engagement with the stop portions.
15. An rack for an appliance, including:
a main section having a support frame adapted to be supported by guide rails on sidewalls within an appliance;
an auxiliary section having an auxiliary platform area, the auxiliary section being adapted to be slidably coupled to the main section to move between a retracted position and an extended position;
a pair of arms coupled to the support frame and each movable relative to the support frame, each arm being resiliently biased away from the main section and configured to abut corresponding stop portions on the guide rails of said sidewalls for inhibiting removal of the main section from an appliance cavity; and
a single release member pivotally coupled to the main section and operatively coupled to both of the arms, actuation of the single release member causing both of the arms disengage from respective stop portions,
wherein each arm includes a convex cam surface,
wherein the single release member includes a pair of link members having convex end portions, movement of the single release member engaging the link members with the convey cam surfaces causing the arms to disengage from the stop portion on the guide rails of said appliance, and
wherein the main section further includes a pair of slides which include a pair of limiting projections each adapted to capture one of the link members between the limiting projection and the convex cam surface.
