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 defining a mechanism-activation aperture;
a soft plastic membrane configured to seal the aperture;
a hard plastic base; and
an actuating button joined to the hard plastic base;
wherein at least one bar secures the base to the housing body and the at least one bar comprises two bars, the two bars arranged in a common plane parallel to a plane of the aperture.
2. The electrical appliance housing of claim 1 , wherein the base is free of through-holes.
3. The electrical appliance housing of claim 1 , wherein the base is free from penetration by the actuating button.
4. The electrical appliance housing of claim 1 , wherein the membrane is directly bonded to the base and the at least one bar.
5. 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 electrical appliance housing.
6. The electrical appliance housing of claim 1 , wherein the actuating button is integrally molded with the hard plastic base.
7. 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.
8. The electrical appliance housing of claim 1 , wherein the actuating button protrudes beyond the membrane towards an outer side of the electrical appliance housing.
9. The electrical appliance housing of claim 1 , wherein the base defines a blind-end bore configured to receive a neck of the actuating button.
10. The electrical appliance housing of claim 1 , wherein the base comprises a radial projection.
11. The electrical appliance housing of claim 1 , wherein the housing body is bonded to the membrane.
12. The electrical appliance housing of claim 1 , wherein the actuating button is positioned on the membrane.
13. The electrical appliance housing of claim 1 , wherein the actuating button is positioned in the membrane.
14. The electrical appliance housing of claim 1 , wherein the at least one bar is integrally molded with the housing body.
15. The electrical appliance housing of claim 1 , wherein the at least one bar is integrally molded with the base.
16. The electrical appliance housing of claim 1 , wherein the at least one bar extends generally parallel to a plane of the aperture.
17. The electrical appliance housing of claim 1 , wherein each of the two bars extends to opposite edges of the aperture.
18. The electrical appliance housing of claim 1 , wherein the two bars is configured to reduce the bending resistance in a direction transverse to the common plane.
19. The electrical appliance housing of claim 18 , wherein each the two bars is shaped in an undulating configuration.
