DESCRIPTION OF THE PREFERRED EMBODIMENTS

(14) The first magnet 22 inside the body 10 is securely attached to the body by a screw 30 as is shown in FIGS. 1 and 2.

(15) FIG. 3 shows the second magnet 34 which when inserted into the body is attachably and detachably held by the magnet 22 in the body. The two magnets are of opposite polarity. The central threaded element 38 in FIG. 3 is an attachment point for the remote control or phone, etc., and can be replaced by adhesive if use of a screw would damage the remote control or phone.

(16) Turning to the drawings in more detail, the insert body 10 has a generally cylindrical open end 12 and a closed end 14, and is adapted to be received in honeycomb sandwich panel 16. The body 10 has a circular flange 18 projecting from open end 12. The flange 18 preferably has spaced apart, preferably diametrically opposed, cutouts or holes 20, one for the introduction of potting material 21, and the other for the venting of air. The method of potting inserts in honeycomb panel and the installation of inserts so that the flange 18 is flush with the adjacent surface of the honeycomb panel is familiar to those skilled in the art.

(17) A cylindrical first magnet 22 having a generally smooth flat outer surface 24 facing the open end of body 10 is snugly received in the open end 12.

(18) A female thread 26 is centrally disposed in opening 27 which extends into the closed end 14 of body 10, stopping short of the terminus of the closed end.

(19) The first magnet 22 has a centrally disposed countersunk threaded clearance hole 28 that allows the male threaded fastener 30 to mate with the female threads 26 in insert body 10.

(20) A male thread fastener 30 is received in thread 26 to secure the magnet 22 to insert body 10. The male thread fastener 30 has a head 32 which is received in the surface 24 of magnet 22 to form a surface which is flush with surface 24, as shown in FIG. 1.

(21) Once the insert with the first magnet has been installed in a panel, a second magnet 34 of opposite polarity to magnet 22, having a smooth surface 36, preferably of approximately the same diameter as magnet 22, can be inserted and magnetically retained in the open end 12 of insert body 10. The magnetic attachment can be overcome by ordinary manual force, so the attachment and detachment of the two magnets can be repeated as often as is required.

(22) FIGS. 6 and 7 illustrate the practical application of the invention.

(23) The magnet 34 may have a male thread stud 38 projecting from the surface 40 opposed to its smooth surface 36.

(24) As shown in FIG. 6, the stud 38 can be threadably attached to a device such as artwork, logos, a remote control or phone.

(25) Alternatively, the stud 38 can be replaced by an adhesive bonding layer 42, as shown in FIG. 7.

(26) The artwork, logos, remote control or phone is indicated generally by the casing or frame 44.

(27) In another embodiment, the magnet 34 need not be sized to the magnet 22. Instead, the magnet 34 can be smaller and stud-like while still being held by magnet 22.

(28) The magnet 22 need not be snugly received in the open end 12 of insert body 10. In general, magnets 22 and 34 can be of any shape so long as the facing surfaces 24 and 36 are essentially smooth to provide a close abutting relationship.

(29) In use, the insert can be secured to the honeycomb panel by potting or any other means known in the art. The panel is preferably honeycomb. However, any type of panel normally provided with inserts may be used.

(30) The insert can first be assembled to the first magnet 22 by screw 30 and then installed in the panel. Alternatively, the insert can be installed in the panel and the first magnet subsequently secured to the insert by screw 30.

(31) The first magnet 22 need not be held by screw 30. Instead, the first magnet can be swagged into or adhesively bonded to the opening 12 in insert body 10.

(32) The magnets are preferably noedymium.

(33) The insert body 10 of the insert can be steel, aluminum, stainless steel, titanium, or plastic of the types well-known in the art. The body 10 is normally non-magnetic.

(34) In the additional alternate preferred embodiment of FIGS. 8 to 10, insert 46 has potting cutouts or holes 48 in top flange 50. The interior of insert 46 has an opening 52 at the top and, initially, an opening at the opposite end 54. A magnet 56 is snugly received in insert 46. The magnet 56 can be swagged in insert 46 or, as shown in FIG. 9, the inside wall of insert 46 can be provided with an area of reduced diameter to form a projection 58. The magnet 56 is then held within the insert 46 between the projection 58 at one of its ends and the other end of magnet 56 is held by element 60 which can be a metal shim which is swagged into the interior of insert 46, securing magnet 56 in place.

(35) In the embodiment of FIGS. 8 to 10, the second magnet is replaced by a ferromagnetic element 62, preferably made of carbon steel or stainless steel which can be attached to and held by magnet 56 and manually detached from said magnet. The ferromagnetic element 62 can be provided with a threaded stud 64. Stud 64 can be attached to devices as explained above. The stud 64 can also be eliminated and replaced by an adhesive bonding layer to adhere to a device.

(36) In FIGS. 11 and 12, the body 110 of the insert has a closed end 114 and an open end 112. The body 110 has a flange 118. A magnet 122 is received in the open end 112 and has a smooth surface 124. The magnet 122 is affixed in the central bore of said body 110. In the panel insert the magnetic member 122 is generally circular in cross-section and received in the central opening with said smooth surface being flush with the open end 112 of the body 110. A female thread 128 is disposed in opening 127. The magnet 122 has a center hole 128. Fastener 130 is received in thread 126 to secure magnet 122 to insert body 110. The head 132 of fastener 130 is received in the surface 124 of magnet 122 to form a surface flush with surface 124. The outer surface of magnet 122 including head 132 is flush with the surrounding flange 118.
