Abstract

The present invention relates to a doormat adapted for outdoor use for melting snow and ice accumulations comprising of a base including a mat element and a bottom portion for engaging with a supporting surface, wherein the mat element is configured for housing heating pipes in electrical engagement with each other that are disposed between the mat element and an upper surface element; at least one removable battery pack, removably attached to the doormat by an electronic port, wherein the heating pipes are powered by removable battery packs connected to the doormat via Universal Serial Bus (“USB”) ports and as such providing for individualized charging of each removable battery pack; and the upper surface element comprising of a brush member with at least one or more apertures for providing access to the removable battery pack for charging the heating pipes disposed within.

First claim

What is claimed is:

1. A doormat comprising of:
a base including a mat element and a bottom portion for engaging with a supporting surface, wherein the mat element is configured for housing heating pipes in electrical engagement with each other that are disposed between the mat element and an upper surface element;
at least one removable battery pack, removably attached to the doormat by an electronic port, wherein the at least one removable battery pack includes a charging circuit and a heating circuit to generate heat when activated and a temperature control element operatively connected to the heating pipes to control activation of the heating pipes depending on the temperature, wherein the temperature control element being located inside the removable battery pack;
a pressure sensor connected to the temperature control element and the heating pipes to activate the heating circuit based on applied pressure; and
the upper surface element comprising of a brush member with at least one or more apertures for providing access to the removable battery pack for charging the heating pipes disposed within.

2. The doormat according to claim 1 , wherein the heating circuit is powered by the at least one removable battery pack or an electrical power cable.

3. The doormat according to claim 1 , wherein the at least one removable battery pack is configured for connection to a power source independent from the doormat.

4. The doormat of claim 1 , wherein the doormat includes a sealing bracket having a substantially rectangular cutout dimensioned to receive the electronic port for the rechargeable removable battery packs to be removable attached thereto.

5. The doormat of claim 4 , wherein a sealing bracket is attached with sealing means for bonding the upper surface to the mat element securing the heating pipes within thereby preventing exposure from weather hazards, and injury due to electrocution.

6. The doormat according to claim 1 , wherein the heating pipes are disposed in a grid formation.

7. The doormat according to claim 3 , wherein the grid formation comprises of the heating pipes running longitudinally and horizontally.

8. The doormat according to claim 1 , wherein the heat is distributed electrically along the heating pipes.

9. The doormat according to claim 1 , wherein the mat element includes a plate with a recessed portion configured for receiving the heating pipes and a portion of the removable battery pack.

10. The doormat according to claim 1 , wherein the brush member is securedly affixed to a plate.

11. The doormat according to claim 1 , wherein the brush member includes a pad comprising of a plurality of miniature monofilament elements.
