Acoustic mount

Abstract

There is disclosed an acoustic mount for dampening vibrations between two structures mounted or coupled in use to each other. The mount includes a vibration dampening member having a first portion, a neck and a second portion. The second portion has a head. The dampening member has a bore running through the 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. A support member is also described to which a second one of the two structures is secured or coupled in use. The support member has an aperture to receive the dampening member. The dampening member is an integral unit and the head can be passed through the aperture and positioned such that said head resists withdrawal through the aperture. The support member is interposed between the first portion and the second portion.

1 . An acoustic mount for dampening vibrations between two structures mounted or coupled in use to each other, said mount comprising: 
 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 defined therein running through said first portion, neck and head to receive a fixing member for engaging or coupling to a first one of the two structures;    a support member to which a second one of the two structures is secured or coupled in use, said support member having an aperture defined therein to receive said dampening member; and    said dampening member being an integral unit and said head being passable through said aperture and positioned such that said head resisting withdrawal through the aperture and said support member being interposed between said first and second portions.    
   
   
       2 . The mount of  claim 1  wherein said aperture is non-circular and said head is shaped to pass through said aperture and then, upon rotation by less than 360°, to resist withdrawal through the aperture.  
   
   
       3 . The mount of  claim 1  wherein said first portion comprises a resilient pad to dampen vibration transmission therethrough between the first one of the two structures and the support member.  
   
   
       4 . The mount of any one of claims  1 , wherein said head has 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.  
   
   
       5 . The mount of  claim 1 , wherein the vibration dampening member has therein an embedded receiver member that extends between said first portion, neck and said second portion, said receiver member has a central bore defined therein 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.  
   
   
       6 . The mount of  claim 5 , wherein the vibration dampening member comprises a vibration dampening material formed about the receiver member such that the receiver member is substantially encapsulated within the vibration dampening material.  
   
   
       7 . The mount of  claim 6 , wherein the vibration dampening material is moulded about the receiver member.  
   
   
       8 . The mount of  claim 7 , wherein the vibration dampening material is a polymeric material, and is formed about the receiver member through a process of vulcanisation.  
   
   
       9 . The mount of  claim 1  wherein said head is oblong in shape and said aperture is correspondingly shaped.  
   
   
       10 . A method of assembling an acoustic mount, comprising: providing a vibration dampening member and a support member, the vibration dampening member being an integral unit having a first portion, a neck, providing a second portion and a bore defined therein, said second portion comprising a head and said bore being adapted to receive a component running through said first portion, neck and second portion, and the support member having an aperture, 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 being interposed between said first and second portions and said head resisting separation of the dampening member from the supported member.  
   
   
       11 . 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 comprising: 
 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 defined therein running through said first portion, neck and head receiving a component engaging or coupling to said first structure;    a support member to which said second structure is being secured or coupled, said support member having an aperture defined therein for receiving said dampening member;    said dampening member being an integral unit and said head having been passed through said aperture and positioned such that said head resisting withdrawal through the aperture and said support member being interposed between said portions, and the component extending through said bore to engage or couple to said first structure, and said second structure being connected to said support member directly or indirectly.    
   
   
       12 . A building structure as claimed in  claim 11  wherein said 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.  
   
   
       13 . 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 defined therein 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 defined therein 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.    
   
   
       14 . A vibration dampening member according to  claim 13 , wherein the body comprises a vibration dampening material formed about the receiver member such that the receiver member is substantially encapsulated within the vibration dampening material.  
   
   
       15 . A vibration dampening member according to  claim 14 , wherein the vibration dampening material is moulded about the receiver member.  
   
   
       16 . A vibration dampening member according to  claim 15 , wherein the vibration dampening material is a polymeric material, and is formed about the receiver member through a process of vulcanisation.  
   
   
       17 . A vibration dampening member according to  claim 13 , wherein the receiver member comprises a cylindrical portion that extends transverse to said head portion so as to extend through said neck and first portion of the body.
