DETAILED DESCRIPTION OF THE DRAWINGS

(25) The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to the precise form disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

(26) Referring initially to FIGS. 1-3B, an illustrative mounting assembly 10 is shown for coupling with a conventional radio handset microphone 12 of the type typically used in emergency vehicles, such as police cars. The radio handset microphone 12 illustratively includes a body 14 receiving internal electrical components, such as a microphone and a speaker (not shown), and supporting an external mechanical hang-up clip 16. The hang-up clip 16 may be of conventional design as including a cylindrical post 18 supporting a disk-shaped tongue 20 integrally formed of a metal, such as aluminum.

(27) As shown in FIGS. 1-4E, the mounting assembly 10 illustratively includes a base 30 having a body 31 formed of the magnetically attractive material (such as a metal), and is configured to be supported by an interior surface 32 of a vehicle (FIG. 3B). More particularly, a fastener, such as mounting screws 33 (FIG. 2B) extending through openings 34 in the body 31 may be used to couple the base 30 to a support, illustratively to the interior surface 32 of the vehicle. Such a support may include, for example, a vehicle dashboard or a center console. As an alternative to the mounting screws 33, mounting bolts 36 and cooperating nuts 38 (FIGS. 2A and 3B) may be used to secure the base 30 to the interior surface 32 of the vehicle. While two mounting screws 33 or bolts 36 are illustrated, it should be appreciated that any number of such fasteners may be used. In yet other illustrative embodiments, different conventional fasteners, such as adhesives and/or tapes may be used to secure the base 30 to a support.

(28) Illustratively, an adapter 40 is configured to couple with the mechanical hang-up clip 16. More particularly, the adapter 40 is secured to the mechanical hang-up clip 16, and releasably couples with the base 30. With reference to FIGS. 1-3B and 5A-5E, the adapter 40 illustratively includes a disc shaped body or housing 42 defined by a first housing member 44a cooperating with a second housing member 44b. Illustratively, the first housing member 44a and the second housing member 44b are substantially identical and illustratively may be molded from a polymer. More particularly, each illustrative housing member 44a, 44b includes a semi-circular body 46 having a proximal or upper wall 48, a distal or lower wall 50, and an arcuate side wall 52 extending longitudinally between the upper wall 48 and the lower wall 50. An inner arcuate groove 54 and an outer arcuate groove 56 are formed within the body 46.

(29) A coupler 60 secures together the first housing member 44a and the second housing member 44b. The coupler 60 illustratively comprises a resilient o-ring 62 received around the disc-shaped housing 42. More particularly, the o-ring 62 may be formed of an elastomer and is received within the outer arcuate grooves 56 of the housing members 44a, 44b. When coupled together along planar interface surfaces 64a and 64b, the housing members 44a and 44b define the disc shaped housing 42. As further detailed herein, the housing members 44a and 44b clamp around the hang-up clip 16 by a retaining force applied by the coupler 60.

(30) The upper wall 48 illustratively includes an arcuate notch 66, and the lower wall 50 illustratively includes an arcuate notch 68. When the housing members 44a and 44b are coupled together to define the housing 42, the notches 66 define a proximal opening 70, and the notches 68 define a distal opening 72.

(31) A proximal chamber 74 is defined by the first housing member 44a and the second housing member 44b. The proximal chamber 74 is configured to receive the tongue 20 of the mechanical hang-up clip 16. The proximal opening 70 is in communication with the proximal chamber 74. The proximal opening 70 is configured to receive the post 18 of the mechanical hang-up clip 16 (FIG. 3).

(32) With reference to FIGS. 2, 3 and 6A-6D, a distal chamber 76 is defined by the first housing member 44a and the second housing member 44b, and is in fluid communication with a distal opening 72. A magnet 80 is received within the distal chamber 76. The magnet 80 illustratively includes a body 82 and a radially outwardly extending mounting rim or lip 84. The body 82 is illustratively received within the distal opening 72, and the mounting lip 84 is illustratively received within the distal chamber 76 (FIG. 3). More particularly, the body 82 extends downwardly from the mounting lip 84 and through the distal opening 72. The magnet 80 may be formed of a conventional material composition, such as ferrite or neodymium. As further detailed herein, the magnet 80 is configured to releasably couple with the base 30, or another magnetically attractive member, via a magnetic force.

(33) With reference to FIGS. 2, 3 and 7A-7D, a shield or cover 86 is illustratively coupled to the magnet 80. More particularly, the shield 86 is illustratively formed of a metal and covers at least a portion of the external surface of the magnet 80. The shield 86 illustratively includes a cap 88 and a radially outwardly extending rim or lip 90. Illustratively, the shield 86 is positioned laterally between the magnet 80 and the side wall 52 of the housing members 44a, 44b, and is positioned longitudinally between the magnet 80 and the base 30. More particularly, the cap 88 extends downwardly from the lip 90 and through the distal opening 72. The shield 86 is configured to protect the magnet 80 from the environment, such as moisture and/or debris. In other illustrative embodiments, the shield 86 may be eliminated. In such illustrative embodiments, the magnet 80 may be protected by a coating or covering, for example, a polymeric coating.

(34) The illustrative mounting assembly 10 coverts the conventional hang-up clip 16 from a mechanical connection with a support, to a magnetic connection with a support. More particularly, the magnet 80 of the mounting assembly 10 is magnetically attracted to a magnetically attractive member, such as the base 30, thereby releasably coupling the radio handset microphone 12 to an interior surface of the vehicle without requiring the user to align the hang-up clip 16 with a conventional mounting slot and groove. The magnetic connection facilitates simple coupling and uncoupling of the microphone 12 with the base 30 or another magnetically attractive member.

(35) Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
