Abstract

A sensing device mounting mechanism, and related method of operating such a mechanism, are disclosed. In at least some embodiments, the mechanism can include a housing that is mountable to a support structure. The housing can define an interior for receiving and supporting a sensing device. The mechanism further includes light pipe device coupled to the housing. The light pipe device can be used to communicate light from a light source to the sensing device, or from the sensing device to a location exterior of the housing such that it can be viewed, detected or received by an operator or other device. Advantageously, the sensing device mounting mechanism is constructed so as to enhance and facilitate, as opposed to interfere with, proper performance of the sensing device.

Claims

1. A sensing device mounting mechanism comprising:

a housing having first and second ends, the housing being mountable to a supporting structure proximate the first end, the housing defining an interior for receiving and supporting a sensing device between the first and second ends, and

a light pipe device coupled to the housing proximate the second end, the light pipe device for communicating a light signal at least one of from a location external to the housing to the sensing device and from the sensing device to the location exterior to the housing, and wherein the light pipe device includes a substantially cylindrical extension portion that extends outwardly from the housing and a frustoconical portion that protrudes into the interior of the housing.

2. The sensing device mounting mechanism of claim 1 wherein the housing further includes a stem portion and a flange portion extending from the stem portion and wherein the housing can be positioned onto to the supporting structure by passing the stem portion through an orifice in the support structure until the flange portion substantially abuts the supporting structure.

3. The sensing device mounting mechanism of claim 1, wherein the light pipe device serves to communicate the light signal from a light source supported by the sensing device to the location exterior to the housing, and wherein the location exterior to the housing is at least one of a first location at which an operator can view the light signal and a second location at which the light signal can be provided to an additional device.

4. The sensing device mounting mechanism of claim 1 wherein the housing further includes a snapping mechanism for securing the housing to the supporting structure via snap-fit engagement.

5. The sensing device mounting mechanism of claim 1 wherein sensing device is rotatably coupled to the housing.

6. The sensing device mounting mechanism of claim 1 wherein the housing is configured to be connected to the supporting structure via at least one of the following:

a snapping mechanism, an adhesive, a screw, a bolt, Velcro®

, and a pair of appendages that clamp onto the supporting structure.

7. The sensing device mounting mechanism of claim 1 wherein the housing further includes a sensing device extension rim for receiving and securing the sensing device within the interior via press-fit engagement.

8. The sensing device mounting mechanism of claim 1 wherein the sensing device located within the interior of the housing comprises a printed circuit board coupled to a plurality of components including a light emitting diode.

9. The sensing device mounting mechanism of claim 1 wherein the housing further includes a stem portion and a flange portion extending from the stem portion and wherein the stem portion further includes a main portion and a hinged portion that is hingedly coupled to the main portion.

10. The sensing device mounting mechanism of claim 9 wherein the hinged portion further comprises at least one snapping mechanism for snap-fit engagement with the main portion.

11. The sensing device mounting mechanism of claim 1 wherein the housing further comprises a stem portion having a plurality of interior snapping mechanisms and a flange portion having a plurality of interior snapping mechanisms, and wherein the stem portion interior snapping mechanisms and the flange portion interior snapping mechanisms engage complementary notches formed in the sensing device so as to secure the sensing device within the interior of the housing.

12. The sensing device mounting mechanism of claim 11 further comprising a spring positioned in overlay relationship with respect to the sensing device, and wherein the spring, when compressed, pushes the stem portion away from the supporting structure, and acts as a tensioning device to hold, in cooperation with the interior snapping mechanism, the sensing device and housing in a mounted position.

13. The sensing device mounting mechanism of claim 1 wherein the housing includes a stem portion, a flange portion extending from the stem portion, and an end cap portion, and wherein the end cap portion includes a pair of snapping mechanisms for snap fit engagement with the stem portion.

14. A sensing device mounting mechanism in combination with a sensing device, the combination comprising:

a sensing device; and

a sensing device mounting mechanism comprising;

a housing having first and second ends, the housing being mountable to a support structure proximate the first end, the housing defining an interior between the first and second ends for receiving and supporting a sensing device, and
