Abstract

A heated wheelchair ramp system includes a ramp constructed from at least one structural insulated panel (SIP) having a foam core sandwiched between two oriented strand board (OSB) panels. A polyaspartic coating covers the SIP panel for allowing the SIP panel to be resistant to outdoor elements. One or more heating elements are configured within channels in the SIP to provide heated to the SIP. A metallic sheet is configured adjacent to the heating element(s) to provide heat distribution to the OSB panel(s). Finally, at least one guardrail or handrail is secured to the side of the SIP for providing a safety barrier to persons using the ramp system.

Claims (30)

1. A heated wheelchair ramp system comprising:

a ramp constructed from at least one structural insulated panel (SIP) having a foam core sandwiched between two oriented strand board (OSB) panels;

a polyaspartic coating covering the SIP panel for allowing the SIP panel to be resistant to outdoor elements;

a heating element configured within the ramp to provide heat to the SIP; and

at least one guardrail secured to the side of the SIP for providing a safety barrier to persons using the ramp system.

2. A heated wheelchair ramp system as in claim 1 , further comprising:

a metallic sheet for distributing heat from the heating element across at least one of the OSB panels.

3. A heated wheelchair ramp system as in claim 1 , wherein the two OSB panels include a first panel that forms a top surface of the ramp system and second panel that forms the bottom surface of the ramp system.

4. A heated wheelchair ramp system as in claim 1 , wherein the foam core includes at least one channel cut therein for placement of the heating element.

5. A heated wheelchair ramp system as in claim 1 , further comprising:

a polyaspartic coating covering the SIP panel for allowing the SIP panel to be resistant to outdoor elements.

6. A heated wheelchair ramp system as in claim 1 , wherein the metallic sheet is aluminum.

7. A heated wheelchair ramp system comprising:

a ramp constructed from at least one structural insulated panel (SIP) having a foam core sandwiched between two oriented strand board (OSB) panels;

a heating element configured within the ramp to provide heat to the SIP;

at least one metallic sheet configured above the heating element for distributing heat from the heating element across at least one of the OSB panels; and

at least one guardrail secured to the side of the SIP for providing a safety barrier to persons using the ramp system.

8. A heated wheelchair ramp system as in claim 7 , wherein the two OSB panels include a first panel that forms a top surface of the ramp system and second panel that forms the bottom surface of the ramp system.

9. A heated wheelchair ramp system as in claim 7 , wherein the foam core includes at least one channel cut therein for placement of the heating element.

10. A heated wheelchair ramp system as in claim 7 , wherein the heating element is installed in a serpentine shape.

11. A heated wheelchair ramp system comprising:

a first oriented strand board (OSB) panel forming a top ramp surface;

a second OSB panel forming a bottom ramp surface;

a foam core sandwiched between the first OSB panel and second OSB panel;

a polyaspartic coating covering the first OSB panel and second OSB panel for allowing the SIP panel to be resistant to outdoor elements;

a heating element configured within foam core to provide heat to at least one of the first OSB panel or second OSB panel;

at least one metallic sheet configured above the heating element for distributing heat from the heating element across the first OSB panel; and

at least one guardrail secured to the side of the SIP for providing a safety barrier to persons using the ramp system.

12. A heated wheelchair ramp system as in claim 11 , wherein the heating element is configured within a channel cut into the foam core.

13. A heated wheelchair ramp system as in claim 11 , wherein the heating element is installed in a serpentine shape.
