Abstract The present invention relates generally to screw accommodating insert devices for installation in panels and more particularly to insert devices adapted for installation in relatively light weight panel structures such as panels comprised of a honeycomb type core bounded by skin sheets. The embodiments of the invention disclosed herein include an adapter member to be accommodated by a complementary cavity formed in a panel, said adapter having a central screw accommodating aperture and hub section, the over all axial extent of the adapter being not substantially greater than the thickness of the panel with which it is to be used. The insert device also includes a pair of superimposed apertured plate members telescopically associated with the hub section and shiftable laterally thereof between concentric and eccentric relation with respect to the hub axis.
The method of installing insert devices within lightweight panels such as panels composed of a honeycomb core bounded by skin sheets and having an insert accommodating cavity extending through one of said sheets and continuing into said core toward the opposite sheet, including the step of placing an insert assembly having a plurality of adjacently disposed, relatively shiftable plate members within the aforesaid panel cavity, engaging with A tool member the outwardly facing sides of the adjacent plate members and linearly shifting the plate members radially of the axis of the insert so as to cause peripheral sections of each plate member to impinge and interlock with the panel core.
