Insulated foot pad for a tripod
First Claim
Patent Images
1. An insulated foot pad to be placed under a foot of an instrument to occupy the space between the foot of the instrument and the instrument'"'"'s supporting surface comprising:
- a first continuous plate of a poor heat conducting material that acts to prevent access of the instrument foot with an insulating layer, the continuous first plate comprising a top surface disposed under the foot of the instrument, and a bottom surface within an edge, at least one hollow pipe extending from the bottom surface of the first continuous plate and away from the edge;
a second continuous plate of a poor heat conducting material that acts to prevent the insulating layer from contacting the supporting surface, the second plate comprising an upper surface and a lower surface, the lower surface contacting the supporting surface, the second plate comprising at least one aperture, the at least one hollow pipe aligning with and contacting the at least one aperture;
the insulating layer disposed between the bottom surface of the first continuous plate and the upper surface of the second continuous plate, the at least one hollow pipe extending through the insulating layer and disposed near the upper surface of the second plate; and
at least one pin protruding through the at least one aperture in the second plate, the at least one pin snaps into an end of the at least one hollow pipe to connect the first continuous plate to the second plate;
wherein the first continuous plate contacts the second continuous plate only through the at least one hollow pipe so that the insulating foot pad reduces the transfer of heat from the foot of the instrument to the supporting surface.

Abstract
An insulated foot pad for a tripod has an insulated block sandwiched between two plates. The plates are made of a material that is a poor conductor of heat. Tripod legs placed on the foot pads will not sink into the snow on sunny days nor into warm asphalt on hot days.
