Abstract
A laundry appliance includes a cabinet frame that defines a receiving aperture. A tub is disposed within the cabinet frame. A suspension support includes an engagement portion. The engagement portion includes an ejection surface sloping in a first direction and an assembling surface sloping in a second opposing direction to a retaining notch. A suspension rod extends between the tub and the suspension support and has a hook for selectively engaging the assembling surface in an installed position and selectively engaging the ejection surface in a misaligned position.
Claims20
A suspension system for a laundry appliance, comprising:
- a bracket configured to couple to a cabinet frame, wherein the bracket defines a depression and a receiving aperture within the depression;
- a suspension support including:
- a base selectively positioned in the depression;
- and
- an engagement portion coupled to the base, wherein the engagement portion has at least one ejection portion having an ejection surface and at least one assembling portion having an assembling surface;
- and
- a suspension rod having a linear portion and a hook with an end, wherein the end of the hook is configured to engage the engagement portion when misaligned to slide in a first direction on the assembling surface along a retaining movement path to an installed position or in a second direction on the ejection surface along a disengaging exit movement path to disengage from the suspension support, and wherein a width of space between the linear portion and the end of the hook is less than each of a minimum thickness of the at least one ejection portion between an inner surface of a central channel and an outer surface and a minimum thickness of the at least one assembling portion between the inner surface of the central channel and the outer surface to promote a sliding engagement between the hook and the suspension support, and further wherein the suspension rod is configured to travel along the retaining movement path to the installed position when the end of the hook engages the at least one assembling surface and along the disengaging exit movement path when the end of the hook engages the at least one ejection surface.

A suspension system for an appliance, comprising:
- a suspension rod having a linear portion and a hook with an end, wherein a space is defined between the linear portion and the end;
- and
- a suspension support including:
- a base;
- and
- an engagement portion coupled to the base, wherein the engagement portion includes an assembling surface and an ejection surface, wherein the end of the hook is configured to slidably engage one of the assembling surface to move in a first direction along a retaining movement path from a misaligned position to an installed position or the ejection surface to move in a second direction along a disengaging exit movement path from the misaligned position to a disengaged position, and wherein each of the assembling surface and the ejection surface has a minimum thickness defined between a surface of a central channel and an outer surface that is less than the space between the linear portion and the end to promote a sliding engagement between the hook and the suspension support.
3 more elements
A suspension support for an appliance suspension system, comprising:
- a base;
- and
- an engagement portion coupled to the base, wherein the engagement portion defines an apex, and wherein the engagement portion includes:
- a first assembling portion having a first assembling surface sloping in a first direction from the apex;
- a second assembling portion spaced from the first assembling portion and having a second assembling surface sloping in the first direction from the apex, wherein each of the first assembling portion and the second assembling portion have a first minimum thickness greater than a width of space defined between an end of a hook and a linear portion of a suspension rod configured to engage the engagement portion to promote a sliding engagement between the end of the hook and the suspension support in the first direction along a retaining movement path from a misaligned position engaging one of the first and second assembling portions to an installed position;
- a first ejection portion proximate to the first assembling portion, wherein the first ejection portion has a first ejection surface that slopes in a second direction from the apex;
- and
- a second ejection portion proximate to the second assembling portion, wherein the second ejection portion has a second ejection surface that slopes in the second direction from the apex, wherein each of the first ejection portion and the second ejection portion have a second minimum thickness greater than the width of space between the end of the hook and the linear portion to promote a sliding engagement between the end of the hook and the suspension support in the second direction along a disengaging exit movement path from a misaligned position engaging one of the first and second ejection portions to a disengaged position.
