Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiments will now be described more fully with reference to the accompanying drawings in which:

[0025] FIG. 1 is a perspective view of an energy transmission control mount;

[0026] FIG. 2 is a rear elevational view of the energy transmission control mount of FIG. 1; and

[0027] FIG. 3 is a side cross-sectional view of the energy transmission control mount interposed between a wall stud and drywall and secured to the wall stud via a fastener.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Turning now to FIGS. 1 and 2, an energy transmission control mount for isolating components such as for example, building structures is shown and is generally identified by reference numeral 10. In this particular example, energy transmission control mount 10 acts between a wall stud and a wall structure such as for example drywall, plaster board, gypsum or the like to reduce the transmission of energy between the wall stud and the wall structure. As can be seen, the energy transmission control mount 10 comprises a generally rectangular carrier 12 formed of metal such as for example steel. The top and bottom ends 14 and 16 of the carrier 12 are folded back over the front surface 18 of the carrier 12 to define channels 20. Vibration dampening material 22 substantially lines each of the channels 20. A central aperture 26 is also provided through the carrier 12. Vibration dampening material 30 substantially lines the aperture 26 and extends over a portion of both the front surface 18 and the back surface 32 of the carrier 12. The vibration dampening material 22 and 30 may be for example polyurethane bonded recycled rubber, polyether urethane foam or other suitable energy absorbing material.

[0029] On the back surface 32, the vibration dampening material 30 is configured to define a plurality of vertically and generally equally spaced, horizontal ribs 34. On the front surface 18, the vibration dampening material 30 is configured to define a disc 36 on which a washer 38 is disposed. The vibration dampening material substantially lines the aperture of the washer 38 and forms an annular flange 40 over the washer 38 to retain the washer on the disc 36. The vibration dampening material 22 substantially lining the channels 20 is isolated from the vibration dampening material 30 substantially lining the aperture 26 and extending over the front surface 18 of the carrier 12. The vibration dampening material 22 and 30 is permanently bonded to the carrier 12

[0030] Turning now to FIG. 3, the energy transmission control mount 10 is shown in use interposed between a wall stud 50 and drywall 52. Energy transmission control mount 10 is designed to increase the sound transmission loss characteristics of the wall stud and drywall assembly. During installation of the energy transmission control mount 10, a fastener 54 is passed through the aligned apertures of the washer 38 and carrier 12 and engages the wall stud 50 to secure the energy transmission control mount 10 to the wall stud 50. The head of the fastener 54 rests on the flange to isolate the head of the fastener 54 from the washer 38. In this position, the ribs 34 bear directly against the wall stud 50. A standard furring channel 56, typically formed of steel, is snapped into the front of the carrier 12 by inserting its upper and lower flanges 58 and 60, respectively, into the lined channels 20 thereby to retain the furring channel. Drywall fasteners (not shown) pass through the drywall 52 and engage the furring channel 56 to secure the drywall 52 to the furring channel 56. In this manner, the energy transmission control mount 10 acts between the drywall 52 and the wall stud 52 to reduce energy from being transmitted therebetween.

[0031] If energy such as vibration or sound is transmitted to the wall stud 50, the ribs 34 resist transmission of that energy to the carrier 12. The vibration dampening material 30 substantially lining the apertures of the carrier 12 and the washer 38 resists transmission of energy to the fastener 54. Energy that is transmitted to the carrier 12 moves to the extremities of the carrier. The vibration dampening material 22 lining the channels 20 resists transmission of this energy to the furring channel 56. In this manner, the energy transmission control mount 10 reduces the transfer of energy between the wall stud 50 and the furring channel 56 and hence the drywall 52.

[0032] In the example described above, the energy transmission control mount is shown interposed between a wall stud 50 and drywall 52. Those of skill in the art will however appreciate that the energy transmission control mount may be used to isolate other building structures such as for example floors and joists, masonry and wall studs, exterior walls and wall studs etc.

[0033] Although the energy transmission control mount is particularly suited to isolate building structures, the energy transmission control mount may be used in other environments to isolate components to inhibit vibration/sound from propagating between components. For example, the energy transmission control mount may be used in automobiles as an engine mount, or as a mount for vehicle body parts.

[0034] Although embodiments have been described, those of skill in the art will appreciate that variations and modifications may be made without departing from the spirit and scope thereof as defined by the appended claims.
