(14) Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-4 show a handle attachment assembly 10 that can be used to secure or attach a handle to a panel 100. In particular, the invention can be used in commercial aircraft where handles are needed to be attached to panels, monuments or the like. However, this is not a limitation on the present invention and the handle attachment assembly 10 can be used elsewhere.

(15) As shown in FIGS. 1-4, in a preferred embodiment, the handle attachment assembly 10 includes first and second insert members 12 that each include a first attachment opening 14 defined therein, and a handle assembly 16 that includes a cover 18 and a main body portion 20. In a preferred embodiment, the attachment openings 14 include a self-locking insert 21. However, this is not a limitation on the present invention and the self-locking insert can be omitted. The main body portion 20 includes a handle portion 22 and first and second attachment portions 24 extending from the handle portion 22. Preferably, the cover 18 is removably connected to the main body portion 20. As shown in FIG. 3, in a preferred embodiment, the cover 18 is connected to the main body portion 20 via fastener, such as threaded fasteners 26 (e.g., screws, bolts, etc.).

(16) As shown in FIG. 3, in a preferred embodiment, the main body portion 20 and the cover 18 cooperate to define a handle interior 28. The first and second attachment portions 24 include first and second attachment members 30 that each include an outer surface 31 and a through hole 32 defined therein. In a preferred embodiment, fasteners 26 extend from the handle interior 28, through the through holes 32 and into the attachment openings 14 in the first and second insert members 12. In another embodiment, the fasteners 26 are permanently attached to and extend from the attachment members 30. In another embodiment, the fasteners 26 extend from the insert members 12, through the through holes 32 and into the handle interior 28.

(17) As shown in FIG. 3, the assembly 10 includes fasteners 26 that extend through openings 33 in the handle portion 22 and into receiver openings 34 defined in boss members in the cover 18 to attach the cover 18 to the main body portion 20.

(18) As shown in FIG. 4, in a preferred embodiment, each insert member 12 includes a central portion 36 having first and second (or top and bottom) flanges 38 and 40 extending therefrom. An adhesive space 42 is defined between the first and second flanges 38 and 40. The attachment opening 14 is defined in the top surface of the central portion 36 and is preferably flush with the first flange 38 to define an attachment surface 44. Preferably, the first and second flanges 38 and 40 both include adhesive openings 46 defined therein. the adhesive openings 46 can be enclosed openings (see the first flange 38) or slots open to the outer edge of the flange (see the second flange 40). As shown in FIGS. 2 and 3, in a preferred embodiment, the first flange 38 is dimensioned such that it is approximately the same size as the inner surface of the attachment member 30 of the handle portion 22 where it is connected.

(19) In use, structural potting compound or other adhesive 50 is used to install or adhere the insert member 12 in an opening 102 in the panel 100 (see FIG. 2). Potting compound 50 is injected through the adhesive openings 46 (four are shown in the drawings) that are defined through the first flange 38. One or more slots (adhesive openings 46) are defined in the second flange 40 that allow potting compound to flow underneath. There can be more or less than four holes and slots. Also, adhesive other than potting compound can be used. In another embodiment, the insert member 12 can be round or another shape other than square. The insert member 12 can be made of metal, plastic, composite or any material that provides sufficient strength. In a preferred embodiment, the insert member 12 is made out of metal. In this embodiment, the shape and size of insert member 12 along with potting compound, the handle attachment assembly provides sufficient strength.

(20) Once the adhesive 50 has set and dried and the insert members 12 are secured in openings 102, the cover 18 is removed and the fasteners 26 are inserted through the through holes 32 and threaded into the attachment openings 14. The cover 18 is then placed on the handle portion 22 and the fasteners 26 are inserted through openings 33 and are threaded into receiver openings 34 to secure the cover 18 on the handle portion 22.
