Abstract

A foot pad has an elastic conical body and at least one elastic rib. The elastic conical body defines a connecting surface and an outer conical surface. The connecting surface defines a hollow portion, and the elastic rib integrally connects to the elastic conical body at a surface of the hollow portion. The outer conical surface has a root portion connecting with an outer edge of the connecting surface. A thickness of the elastic conical body at the root portion of the outer conical surface is greater than a thickness of the elastic conical body at other portions of the outer conical surface. Elasticity of the foot pad is thereby increased so as to enlarge a contact area contacting an outer supporting surface, so that an anti-skid effect is improved and the foot pad is capable of absorbing a deformation of an electronic product.

Claims

1. A foot pad, comprising:

an elastic conical body, the elastic conical body being readily deformable, the elastic conical body having a connecting surface, and a hollow portion, the elastic conical body being without any protrusion extending above the connecting surface, the connecting surface being at a top of the elastic conical body, the hollow portion being surrounded by an inner surface of the elastic conical body, a top of the hollow portion being surrounded by an inner circumference of the connecting surface; and

at least one elastic rib, the at least one elastic rib being readily deformable, the at least one elastic rib integrally connecting to the inner surface of the elastic conical body.

2. The foot pad as claimed in claim 1, wherein the elastic conical body defines an outer conical surface, the outer conical surface having an apex for contacting an outer supporting surface and a root portion connecting with an outer edge of the connecting surface, wherein a thickness of the elastic conical body at the root portion of the outer conical surface is greater than a thickness of the elastic conical body at the apex of the outer conical surface.

3. The foot pad as claimed in claim 1, wherein the elastic conical body defines an outer conical surface, the outer conical surface having an apex for contacting an outer supporting surface and a root portion connecting with an outer edge of the connecting surface, wherein a thickness of the elastic conical body at the root portion of the outer conical surface is greater than a thickness of the elastic rib.

4. The foot pad as claimed in claim 1, wherein the elastic ribs are arranged perpendicular to each other.

5. The foot pad as claimed in claim 1, wherein the elastic ribs are arranged parallel to each other.

6. The foot pad as claimed in claim 1, wherein the elastic conical body and the elastic ribs are made of silicone.

7. The foot pad as claimed in claim 1, wherein the elastic conical body and the elastic ribs are made of natural rubber.

8. The foot pad as claimed in claim 1, wherein the at least one elastic rib transversely crosses the entire hollow portion and contacts the inner surface of the elastic conical body.

9. The foot pad as claimed in claim 8, wherein two ends of the at least one elastic rib contact the inner circumference of the connecting surface.
