Electrical appliance housing
View Patent ↗An electrical appliance housing including a hard plastic housing body defining a switch-actuating aperture. The aperture is sealed with a soft plastic membrane. An actuating button is fastened to a hard plastic base that is bonded to the membrane.
1. An electrical appliance housing, comprising:
a hard plastic housing body having a wall with an aperture, the housing body having at least one integrally molded bar extending into the aperture, the at least one integrally molded bar having a free end supporting a base, wherein the at least one integrally molded bar extends generally parallel to a plane of the aperture;
a soft plastic membrane directly bonded to the base and the at least one bar so no water can reach an interior of the housing and the at least one integrally molded bar supports the membrane; and
an actuator button fastened to the base, the actuator button and the base are separate components that are joined together, wherein the actuating button protrudes beyond the membrane towards an outer side of the housing body.
2. The electrical appliance housing of claim 1 wherein a surface of the membrane facing an outer side of the housing body lies lower than a level of the wall of the housing body surrounding the aperture.
3. The electrical appliance housing of claim 1 wherein the base has a radially projecting shoulder.
4. The electrical appliance housing of claim 1 wherein the base is aligned roughly central to the aperture.
5. The electrical appliance housing of claim 1 wherein the membrane is bonded to the housing body.
6. The electrical appliance housing of claim 1 wherein the membrane projecting toward an outside of the housing has an annular collar engaging the actuator button.
7. The electrical appliance housing of claim 1 wherein the actuator button is raised relative to the membrane.
8. The electrical appliance housing of claim 1 , wherein the membrane includes an edge section that encloses the base and projects beyond the base towards an outer side of the housing body.
9. The electrical appliance housing of claim 1 , wherein the membrane defines a recess, at least an outer side of the base penetrating the membrane through the recess.
10. The electrical appliance housing of claim 1 , wherein the base receives a neck of the actuating button.
11. The electrical appliance housing of claim 1 , wherein the actuating button is positioned on the membrane.
12. The electrical appliance housing of claim 1 , wherein the actuating button is positioned in the membrane.
13. The electrical appliance housing of claim 1 , wherein the at least one integrally molded bar is integrally molded with the base.
14. The electrical appliance housing of claim 1 , wherein the at least one integrally molded bar extends approximately at a lower edge of the aperture.
15. The electrical appliance housing of claim 1 , wherein the at least one integrally molded bar comprises two bars, the two bars arranged in a common plane parallel to a plane of the aperture.
16. The electrical appliance housing of claim 15 , wherein each of the two bars extends to opposite edges of the aperture.
17. The electrical appliance housing of claim 15 , wherein the two bars is configured to reduce the bending resistance in a direction transverse to a common plane.
18. The electrical appliance housing of claim 15 , wherein each the two bars is shaped in an undulating configuration.
19. The electrical appliance housing of claim 15 , wherein the two bars are integrally molded with the base.
20. The electrical appliance housing of claim 1 wherein the actuator button is pressed fit or adhesively bonded to the base.
