Abstract

A mounting system for mounting a pressure switch to a mounting body without using screws or brackets. The mounting system includes a support physically supporting the pressure switch on the mounting body, a conduit carrying a pressure signal from the mounting body to the pressure switch, and a connector extending between and connecting the support to the conduit. The support and conduit may have ends constructed of synthetic rubber to frictionally engage support and conduit mounts, and the support and conduit may have approximately the same length and/or the same cross-sectional shape. The mounting body may be a draft inducer, a condensate collector box, or a drain trap in a furnace.

First claim

Having thus described one or more embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

1. A mounting system for mounting a pressure switch to a mounting body, wherein the pressure switch includes a first mount and a first tap and the mounting body includes a second mount and a second tap, the mounting system comprising:
a support configured to physically support the pressure switch on the mounting body, the support including—
a first support end configured to engage the first mount of the pressure switch,
a second support end configured to engage the second mount of the mounting body, and
an intermediate support portion extending between the first and second support ends; and

a conduit connected to the support and configured to carry a pressure signal from the mounting body to the pressure switch, the conduit including—
a first conduit end configured to engage the first pressure tap of the pressure switch,
a second conduit end configured to engage the second pressure tap of the mounting body, and
an intermediate conduit portion extending between the first and second ends.

2. The mounting system of claim 1 , wherein the support and the conduit have approximately a same length and a different cross-sectional shape.

3. The mounting system of claim 1 , wherein the support and the conduit have a different length and a different cross-sectional shape.

4. The mounting system of claim 1 , wherein the support and the conduit have approximately a same length and a same cross-sectional shape.

5. The mounting system of claim 1 , wherein the support and the conduit share a common longitudinal axis.

6. The mounting system of claim 1 , wherein the support is directly connected to the conduit.

7. The mounting system of claim 1 , further including a connector configured to connect the support and the conduit, the connector including—
a first connector side attached to the support,
a second connector side attached to the conduit, and
an intermediate connector portion extending between the first and second sides and connecting the support to the conduit.

8. A mounting system for mounting a pressure switch to a mounting body in a furnace, wherein the pressure switch includes a first mount and a first tap and the mounting body includes a second mount and a second tap, the mounting system comprising:
a support configured to physically support the pressure switch on the mounting body, the support including—
a first support end constructed of a synthetic rubber and configured to frictionally engage the first mount of the pressure switch,
a second support end constructed of the synthetic rubber and configured to frictionally engage the second mount of the mounting body, and
an intermediate support portion extending between the first and second support ends;

a conduit connected to the support and configured to carry a pressure signal from the mounting body to the pressure switch, the conduit including—
a first conduit end constructed of the synthetic rubber and configured to frictionally engage the first pressure tap of the pressure switch,
a second conduit end constructed of the synthetic rubber and configured to frictionally engage the second pressure tap of the mounting body, and
an intermediate conduit portion extending between the first and second ends; and

a connector configured to connect the support and the conduit, the connector including—
a first connector side attached to the support,
a second connector side attached to the conduit, and
an intermediate connector portion extending between the first and second sides and connecting the support to the conduit.

9. The mounting system of claim 8 , wherein the synthetic rubber is ethylene propylene diene terpolymer.

10. The mounting system of claim 8 , wherein the support and the conduit have approximately a same length and a same cross-sectional shape.

11. A furnace comprising:
a pressure switch including a first mount and a first tap;
a mounting body including a second mount and a second tap; and
a mounting system for mounting the pressure switch to the mounting body, the mounting system including—
a support physically supporting the pressure switch on the mounting body, the support including—
a first support end engaging the first mount of the pressure switch,
a second support end engaging the second mount of the mounting body, and
an intermediate support portion extending between the first and second support ends,

a conduit connected to the support and configured to carry a pressure signal from the mounting body to the pressure switch, the conduit including—
a first conduit end engaging the first pressure tap of the pressure switch,
a second conduit end engaging the second pressure tap of the mounting body, and
an intermediate conduit portion extending between the first and second ends.

12. The furnace of claim 11 , wherein the first and second support ends engage the first and second mounting projections, respectively, and the first and second conduit ends engage the first and second pressure taps, respectively, with friction fits.

13. The furnace of claim 12 , wherein the first and second mounting projections receive the first and second support ends, respectively.

14. The furnace of claim 12 , wherein the first and second conduit ends receive the first and second pressure taps, respectively.

15. The furnace of claim 11 , wherein the support and the conduit have approximately a same length and a same cross-sectional shape.

16. The furnace of claim 11 , wherein the support and the conduit share a common longitudinal axis.

17. The furnace of claim 11 , wherein the support is directly connected to the conduit.

18. The furnace of claim 11 , the mounting assembly including a connector interconnecting the support and the conduit, the connector including—
a first connector side attached to the support,
a second connector side attached to the conduit, and
an intermediate connector portion extending between the first and second sides and connecting the support to the conduit.

19. The furnace of claim 11 , wherein the mounting body comprises a draft inducer.

20. The furnace of claim 11 , wherein the first and second mounts each comprises a projection received in the respective one of the support ends of the support.
