Description
- The present application claims priority from Australian Provisional Patent Application No 2006905693 filed on 16 Oct. 2006.
- The present invention relates to an acoustic mount which may be used in applications where it is desirable to reduce transmission of acoustic vibrations from one area to another. The acoustic mount of the invention may have applications for example in industrial, automotive or building environments.
- Vibrations are transferred between structures, such as walls and the like, via abutting or connecting points. In the building industry, for example, external masonry walls are often clad internally with thinner plaster board walls which are secured at mounting or connecting points to the external wall. Noise travels from the masonry wall via these connecting points to the plaster board walls and vice versa. A similar situation occurs internally between adjacent areas or rooms where noise is transferred by connecting points between internal wall components. Likewise vibrations travel between industrial machinery and its housings and its mountings, and between automobile engines or other vibration sources and the vehicle body and vehicle interior via connecting points.
- There are products used in the building industry to dampen transfer of vibrations at connecting points on walls, or between a floor and its support structure, or between a structure and a cladding. These products include a resilient sound dampening pad between one structure and a bracket that, in use, is mounted to an adjacent structure.
- One example mount is that disclosed in Australian patent number 758716. This discloses an acoustic mount assembly comprising three assembled parts; a pad, a bracket and a metal bush. The mount assembly comprises an acoustic pad with an integral sleeve extending at right angles. The sleeve has a thread on its external surface. The pad is mounted in an opening on the bracket by screwing the sleeve into the opening. The metal bush, which comprises a tubular portion and a flange, is inserted into the rubber sleeve to complete assembly of the mount. The fixing member, such as a screw, passes through the bush in use.
- Another known mount also comprises three parts, a pad with a sleeve, a bracket and an annular cap which fits onto the sleeve to complete the assembly after being passed through an aperture in the bracket.
- The above references to and descriptions of prior proposals or products are not intended to be, and are not to be construed as, statements or admissions of common general knowledge in the art in Australia.
- The present invention in a first aspect provides an acoustic mount for dampening vibrations between two structures mounted or coupled in use to each other, said mount including:
- a. a vibration dampening member having a first portion, a neck and a second portion, said second portion comprising a head, and said dampening member having a bore running through said first portion, neck and head to receive a component, such as a fixing member such as a screw, for engaging or coupling to a first one of the two structures; and
- b. a support member to which a second one of the two structures is secured or coupled in use, said support member having an aperture to receive said dampening member;
- wherein said dampening member is an integral unit and said head can be passed through said aperture and positioned such that said head resists withdrawal through the aperture and that said support member is interposed between said portions.
- When used in this specification, including the claims, the term “structure” is intended and is to be interpreted to include not only structural elements which are rigid and provide structural strength but also structures or component elements which are part of a multi-part or complex system and through which vibrations can be transmitted but which do not necessarily provide any rigidity or serve purposes involving structural strength. For example, in suspended ceilings in buildings, ceiling panels or elements can be suspended by rods or wires and the acoustic mount of the invention can be applicable where each of such rods comprises one of the structures, or perhaps two rods meeting end to end constitute the structures with the acoustic mount interposed between the ends. Other types of structures in the building industry with which the acoustic mount of the invention can be used include ceilings, floors, walls (including structural strength walls, infill walls, partition walls), any types of cladding both internal and external e.g. plaster board, villa board.
- In one possible embodiment, the aperture of the support member is non-circular and the head is shaped to pass through the aperture and then, upon rotation by less than 360°, to resist withdrawal through the aperture.
- The first portion may comprise a resilient pad to dampen vibration transmission therethrough between the first one of the two structures and the support member.
- In one form, the head may have therein an embedded washer with a central hole aligned with the bore and the washer resists excessive travel of the fixing member through the bore during use of the mount.
- In another form, the vibration dampening member may have therein an embedded receiver member that extends between said first portion, neck and said second portion, said receiver member having a central bore that aligns with the bore of the vibration dampening member and a head portion that is received within the head of the second portion of the vibration dampening member, the head portion thereby resists excessive travel of the fixing member through the bore of the vibration dampening member during use of the mount. The vibration dampening member may comprise a vibration dampening material formed about the receiver member such that the receiver member is substantially encapsulated within the vibration dampening material. The vibration dampening material may be moulded about the receiver member. The vibration dampening material may be a polymeric material, such as a rubber material, and may be formed about the receiver member through a process of vulcanisation.
- The head may be oblong in shape and the aperture may be correspondingly shaped. For example, the aperture may be rectangular or generally rectangular with rounded corners.
- The present invention also provides in a second aspect a method of assembling an acoustic mount comprising a vibration dampening member and a support member, the vibration dampening member being an integral unit having a first portion, a neck, a second portion and a bore, said second portion comprising a head and said bore being adapted to receive component such as a fixing member running through said first portion, neck and second portion, and the support member having an aperture,
- wherein said method comprises passing said head through the aperture and rotating said dampening member less than 360° around the axis of the bore such that said support member is interposed between said first and second portions and said head resists separation of the dampening member from the supported member.
- The present invention also provides in a third aspect a building structure having means for dampening sound vibrations travelling from a first structure of the building to a second structure of the building wherein said first and second structures are connected at connecting points, said building structure having at each of said connecting points an acoustic mount for dampening vibrations travelling between the first and second structures, said mount including:
- a. a vibration dampening member having a first portion, a neck and a second portion, said second portion comprising a head, and said dampening member having a bore running through said first portion, neck and head receiving a component, such as a fixing member such as a screw, engaging or coupling to said first structure; and
- b. a support member to which said second structure is secured or coupled, said support member having an aperture receiving said dampening member;
- wherein said dampening member is an integral unit and said head has been passed through said aperture and positioned such that said head resists withdrawal through the aperture and said support member is interposed between said portions, wherein said component, such as the fixing member, extends through said bore to engage or couple to said first structure, and said second structure is connected to said support member directly or indirectly.
- In a preferred use in the building field, the first structure comprises a structural wall or floor of the building and said second structure comprises an internal wall or ceiling spaced from and mounted by the structural wall or floor.
- According to yet another aspect, the present invention comprises a vibration dampening member, comprising:
- a body having a first portion, a neck and a second portion, said second portion comprising a head and said body having a bore extending through said first portion, neck and head; and
- a receiver member embedded within said body so as to extend between said first portion, neck and said second portion, said receiver member having a central bore that aligns with the bore of the body and a head portion that is embedded within the head of the second portion of the body.
- The body may comprise a vibration dampening material formed about the receiver member such that the receiver member is substantially encapsulated within the vibration dampening material. The vibration dampening material may be moulded about the receiver member. The vibration dampening material may be a polymeric material, such as a rubber material, and may be formed about the receiver member through a process of vulcanisation.
- The receiver member may comprise a cylindrical portion that extends transverse to said head portion so as to extend through said neck and first portion of the body.
- Possible and preferred features of the present invention will now be described with particular reference to the accompanying drawings. However it is to be understood that the features illustrated in and described with reference to the drawings are not to be construed as limiting on the scope of the invention.

aperture 2 is non-circular such as rectangular, triangular or other suitable shape with acute or rounded angles at its corners. In such case,head 17 is correspondingly sized and shaped. When the mount is assembled, thesupport member 1 is interposed betweenfirst portion 14 andhead 17 of thevibration dampening member 12. - The mount shown in the drawings is easily assembled in one process.
Head 17 is aligned withaperture 2 as shown inFIG. 7 and then passed throughaperture 2 and then rotated 90° so that it resists withdrawal throughaperture 3. The flat side edges 13 of thefirst portion 14 provide visual confirmation to a person assembling the mount when thehead 17 is aligned with the rectangular aperture 2 (FIG. 7 ) and when the head is at 90° to the aperture 2 (FIG. 2 ). - The
vibration dampening member 12 may be made of any suitable material such as rubber or thermoplastic polymer of the required hardness. The degree of hardness may depend in part upon the design of thehead 17 andcomplementary aperture 2, particularly if compression of thehead 17 is required to pass it through the aperture, as well as upon the vibration dampening properties required. - In use, as shown in
FIG. 1 , the mount comprises the assembly of thesupport member 1 andvibration dampening member 12. Thevibration dampening member 12 is located in position against thefirst structure 5, which may be a structural building wall, andfastener screw 8 is passed into thebore 19 and driven into thestructure 5. As thescrew 8 is secured into thestructure 5, the head of thescrew 8 encounters resistance from the embeddedwasher 20, thereby limiting penetration of the screw into thestructure 5. The second part of thestructure 6 can then be assembled, as shown in the illustrated embodiment, by engagingfurring channel 4 with theears 3 of thesupport member 1. The facing panel 7 (e.g. plasterboard if internal, or cladding if external) of the second part of thestructure 6 is mounted to thefurring channel 4. - Vibrations, particularly from noise, will be dampened in passing between the
first structure 5 and thesecond structure 6. This is primarily due to the fact that the acoustic mount comprises the connection point between thefirst structure 5 and thesecond structure 6. As can be seen, thesupport member 1, which is rigidly coupled to thesecond structure 6, has portions of thevibration dampening member 12 interposed between thefirst structure 5 and mountingscrew 8. In particular, thefirst portion 14, which is made of resilient vibration dampening material, is interposed directly between thesupport member 1 and thestructure 5. Similarly, the integralenlarged head 17, which is composed of the same resilient vibration dampening material, is interposed between thesupport member 1 and thefastening screw 8. - It will be appreciated that variations in the details of construction of the acoustic mount are possible without departing from the scope of the invention. As already mentioned, for example, the shape of the head and complementary shaped aperture can be varied from the generally rectangular shape shown in the drawings to other oblong shapes, or triangular shape, or other non-circular shapes, or to a bayonet like configuration with the head comprising an extension of the neck and having one or more projections extending laterally which can pass through complementary concavities at the profile of the aperture enabling the head to be inserted and then rotated so that the projections resist withdrawal.
- The washer, instead of being embedded in the head in the moulding process of manufacture of the vibration dampening means, could be assembled e.g. by being adhered to the surface of the head with the aperture of the washer aligned with the bore through the vibration dampening means. The washer could be annular as illustrated or could be oblong in the case of an oblong head.
- The acoustic mounts in FIGS. 9 to 11 exemplify other embodiments useable in the building industry.
-
FIG. 9 shows a different type of furringchannel support member 30, as is known in the industry, which has spaced opposed lines of multiple support lugs 31 for supporting a furring channel in selectively variable positions. -
FIG. 10 shows an angle support member orbracket 35 having aleg 36 which can be mounted by screws etc to a first structure such as a structural wall, and anarm 37 at right angles for supporting or otherwise being coupled to another second structure, e.g. a floor at right angles to the first structure. - In both
FIGS. 9 and 10 thevibration dampening member 12 is assembled with thesupport -
FIG. 11 shows an acoustic mount 40 for a suspension wire or suspension rod system, e.g. useable for a suspended ceiling system. Thevibration dampening member 12 of the same construction as the first embodiment is coupled to a support member 41 having acentral aperture 42 which receives the neck of themember 12. Support member 41 in turn has awire 44 with aloop 45 to couple to aceiling suspension rod 46. Anotherwire loop 47 is arranged to couple toupper suspension rod 48. Theloop 47 has dependingarms 49 that pass through thebore 19 and engage withwasher 20. It will be seen that acoustic vibrations will not be transmitted betweenrods member 12 that is interposed between those rods. - An alternative embodiment of a vibration dampening member suitable for use in an acoustic mount of the present invention is shown in
FIG. 12 asreference numeral 50. As is the case with the dampeningmember 12 of the embodiment ofFIG. 1 , dampeningmember 50 is in the form of single body having an integralfirst portion 54,neck 55, and asecond portion 56. Thesecond portion 56 is in the form of a head that is shaped and sized to be passed through an aperture formed in a support member, in the manner as previously described. - The body of the dampening
member 50 is formed by moulding a suitable dampening material, such as rubber or a thermoplastic polymer, about aninner receiver member 51, so as to form amember 50 of the desired shape, as shown. The body of the dampeningmember 50 thereby comprises anouter layer 52 of dampeningmaterial 52 formed about aninner receiver member 5 1, with theouter layer 52 and theinner member 51 being vulcanised together to form the dampeningmember 50. In this arrangement, theinner receiver member 51 is encapsulated within theouter layer 52 such that themember 51 is separable from theouter layer 52, only by destruction of themember 50. - The
outer layer 52 of dampening material is moulded about the inner receiver member so as to form thefirst portion 54,neck 55, andsecond portion 56. One or more protuberances may be formed on the surface of thefirst portion 54 to abut with a surface of first structure of a building during use. Such an arrangement aids in dampening any vibrations that may transfer between thefirst portion 54 and the first structure of the building. - An alternative arrangement of the dampening member is shown in
FIG. 14 . In this arrangement, theouter layer 52′ of dampening material is moulded about the inner receiver member (not shown) to form the body of the dampeningmember 50′. Thefirst portion 54′ is formed such that a plurality ofvoid regions 59′ are formed therein and a plurality ofprotuberances 58′ are formed on the surface thereof. As in the previously described embodiment, theprotuberances 58′ are provided to abut with a surface of the first structure of the building during use to facilitate dampening any vibrations that may transfer between thefirst portion 54 and the first structure of the building. Theprotuberances 58′ may have rounded ends or the ends may be flat or dimpled, as desired. Thevoid regions 59′ provided between theprotuberances 58′, further aid in this dampening function by reducing the weight and increasing the flexibility and surface area of the dampeningmember 50′. It will be appreciated that the embodiment of the dampeningmember 50′ as shown inFIG. 14 may also be employed in the mount arrangements shown inFIGS. 1-11 . - The
inner receiver member 51 is shown in more detail inFIGS. 13A and 13B , and comprises a substantiallycylindrical body portion 51 a and ahead portion 51 b. Thebody portion 51 a extends orthogonally from thehead portion 51 b and has abore 53 formed therein that extends through thebody portion 51 a and thehead portion 51 b as shown inFIG. 13B . Whilst thebody portion 51 a is shown as having a substantiallycircular bore 53, it will be appreciated that other bore 53 shapes are also envisaged. - Referring to
FIG. 13A , thehead portion 51 b has a substantially rectangular shape with a plurality of through-holes 57 provided therethrough. The shape of thehead portion 51 b of theinner receiver member 51 generally determines the shape of thesecond portion 56 of the dampeningmember 50. In this regard, theouter layer 52 of dampening material is moulded about thehead portion 51 b. The provision of the through-holes 57 improves bonding between the layer of dampening material and thereceiver member 51. - As shown in
FIG. 12 , when the dampeningmember 50 is formed by moulding theouter layer 52 of dampening material about theinner receiver member 51, thebore 53 of theinner receiver member 51 extends through the dampeningmember 50. As theinner receiver member 51 is made from a rigid metal or plastic material, the structural integrity of the dampeningmember 50 is significantly greater than that described in the previous embodiments. This is particularly so in those regions proximal thebore 53 and outer surface of thesecond portion 56, which are in direct contact with the fastening members that couple the first and second structures of the building. As such, the dampening material is able to experience significant forces without the rubber, or other such dampening material collapsing or deteriorating under load. - It will be appreciated that the dampening
member 50 will be employed in a building or the like to dampen vibrations between structures in the manner as shown inFIG. 1 orFIG. 11 , or any other such manner. - It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
- When used in this specification and claims, the terms “comprises” and “comprising” and variations thereof mean that the specified features, steps or integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
- It is to be understood that various alterations, modifications and/or additions may be made to the features of the possible and preferred embodiment(s) of the invention as herein described without departing from the spirit and scope of the invention.
