Abstract

A button comprising a core including a face defining at least one slot and a shaft extending outwardly from the face. The core is preferably made from a rigid material. An outer portion is connected to the core and at least partially surrounds the face. The outer portion is preferably made from a flexible resilient material. A relatively flat cap includes a base with a front side and a back side disposed opposite one another. A foil is connected to the front side and at least one rib projects outwardly from the back side. The rib extends into the slot to connect the cap to the core. The face can define three slots and the cap can include three ribs projecting outwardly from the back side. Each rib extends into a corresponding slot to connect the cap to the core.

Claims

1. A button comprising:

a core, the core being made from a rigid material, the core having a face forming a display side of the core, a reverse side opposite to the display side, at least one slot having an opening on the display side of the core and an opposite opening on the reverse side of the core, and a shaft extending outwardly from the reverse side of the core;

an outer portion connected to the core and at least partially surrounding the face, the outer portion being made from a flexible resilient material; and

a relatively flat cap including a base with a front side and a back side disposed opposite one another, a foil connected to the front side, and at least one rib projecting outwardly from the back side of the cap, the rib extending into the slot of the core through the one opening of the slot on the display side of the core and through the opposite opening of the slot on the reverse side of the core, whereupon the rib extends completely through the slot of the core.

2. The button of claim 1, wherein the face includes a ridge defining a recessed area and the cap is at least partially disposed within the recessed area.

3. The button of claim 1, wherein the outer portion is connected to the core with a two cavity molding process.

4. The button of claim 1, wherein the rib is fused to the core with a welding process.

5. The button of claim 1, wherein the face defines three slots and the cap includes three ribs projecting outwardly from the back side, each rib extending into a corresponding slot and connecting the cap to the core.

6. The button of claim 5, wherein the ribs are not sized uniformly with respect to one another and the slots are not sized uniformly with respect to one another.

7. The button of claim 1, wherein the core is made from a polypropylene material.

8. The button of claim 1, wherein the outer portion is made from a rubber material.

9. The button of claim 1, wherein the base is made from an acrylonitrate butadiene-styrene material.

10. The button of claim 1, wherein the foil includes an inner layer made from a chromium material and an outer layer made from a polymethylmethacrylate material, the inner layer being disposed between the outer layer and the base.

11. A household appliance comprising:

a housing;

a control panel supported by the housing, the control panel having a button shaft receiving aperture; and

a button mounted in the control panel and including;

a core, the core being made from a rigid material, the core having a face forming a display side of the core, a reverse side opposite to the display side, at least one slot having an opening on the display side of the core and an opposite opening on the reverse side of the core, and a shaft extending outwardly from the reverse side of the core, an outer portion connected to the core and at least partially surrounding the face, the outer portion being made from a flexible resilient material, and a relatively flat cap including a base with a front side and a back side disposed opposite one another, a foil connected to the front side, and at least one rib projecting outwardly from the back side of the cap, the rib extending into the slot of the core through the one opening of the slot on the display side of the core and through the opposite opening of the slot on the reverse side of the core, whereupon the rib extends completely through the slot of the core, and the shaft of the core is received in the button shaft receiving aperture of the control panel.

12. The household appliance of claim 11, wherein the household appliance includes a washing machine having a rotating drum and a drive device coupled to the rotating drum disposed within the housing, the drive device driving the rotating drum in response to actuation of the button on the control panel.

13. The household appliance of claim 11, wherein the face defines three slots and the cap includes three ribs projecting outwardly from the back side, each rib extending into a corresponding slot and connecting the cap to the core.

14. The household appliance of claim 13, wherein the ribs are not sized uniformly with respect to one another and the slots are not sized uniformly with respect to one another.

15. The household appliance of claim 11, wherein the core is made from a polypropylene material, the outer portion is made from a rubber material, and the base is made from an acrylonitrate butadiene-styrene material.

16. The household appliance of claim 11, wherein the foil includes an inner layer made from a chromium material and an outer layer made from a polymethylmethacrylate material, the inner layer being disposed between the outer layer and the base.
