Abstract
Abstract A method is disclosed of folding a honeycomb panel, the panel preferably comprising a honeycomb core having opposing face sheets. A slit is preferably cut through one face sheet and the underlying honeycomb core and a wedge is driven into the honeycomb panel at the location of the slit. The wedge crushes the honeycomb core to a preselected depth with a preselected angle whereby the crushed honeycomb core forms a hinge. The honeycomb panel can then folded along the hinge in a direction opposite the intact face sheet. Adhesives can be used to hold the hinge in the folded position.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
106 words
A method of folding a honeycomb panel along a predetermined line, the method comprising: a) partially cutting a slit into the honeycomb panel along the predetermined line; b) providing a wedge having an angle and a vertex; c) driving the wedge having the vertex into the honeycomb panel along the predetermined line to crush a portion of the honeycomb panel, the crushed portion of the honeycomb panel forming an angle that is less than the wedge angle and forming a hinge; d) folding the honeycomb panel along the hinge to a folded position; and e) providing adhesive means to hold the hinge in a folded position.
Claim 2
Independent Claim
106 words
A method of folding a honeycomb panel along a predetermined line, the method comprising: a) partially cutting a slit into the honeycomb panel along the predetermined line; b) providing a wedge having an angle and a vertex; c) driving the wedge having the vertex into the honeycomb panel along the predetermined line to crush a portion of the honeycomb panel, the crushed portion of the honeycomb panel forming an angle that is less than the wedge angle and forming a hinge; d) folding the honeycomb panel along the hinge to a folded position; and e) providing adhesive means to hold the hinge in a folded position.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein the adhesive means is glue applied to at least a part of the crushed portion of the honeycomb panel.
Claim 4
Dependent Claim
13 words
The method of claim 2 wherein the glue is a dry contact adhesive.
Claim 5
Dependent Claim
27 words
The method of claim 1 wherein the adhesive means is double-sided adhesive tape applied to at least a part of the crushed portion of the honeycomb panel.
Claim 6
Dependent Claim
29 words
The method of claim 1 wherein the honeycomb panel comprises a honeycomb core having opposing face sheets, the slit being cut through one face sheet along the predetermined line.
Claim 7
Dependent Claim
26 words
The method of claim 1 wherein at least a portion of the honeycomb core is slit along with the one face sheet along the predetermined line.
Claim 8
Dependent Claim
31 words
The method of claim 1 wherein the adhesive means is a single-sided adhesive tape applied after folding, the adhesive tape covering the hinge and the slit face sheet abutting the hinge.
Claim 9
Dependent Claim
13 words
The method of claim 7 wherein the single-sided tape is a non-slip tape.
Claim 10
Dependent Claim
13 words
The method of claim 7 wherein the single-sided tape is a slippery tape.
Claim 11
Dependent Claim
23 words
The method of claim 1 wherein the adhesive means is a pressure-sensitive adhesive applied only to the crushed portion of the honeycomb panel.
Claim 12
Dependent Claim
19 words
The method of claim 1 wherein the wedge angle is greater than 90 degrees and less than 120 degrees.
Claim 13
Dependent Claim
13 words
The method of claim 11 wherein the vertex is a rounded radius corner.
Claim 14
Dependent Claim
12 words
The method of claim 11 wherein the vertex is a sharp point.
Claim 15
Dependent Claim
17 words
The method of claim 11 wherein the step of cutting is done before the step of driving.
Claim 16
Dependent Claim
19 words
The method of claim 11 wherein the steps of cutting and driving are done at substantially the same time.
Claim 17
Independent Claim
88 words
A method of manufacturing a foldable honeycomb panel, the method comprising the steps of: a) cutting a slit into a honeycomb panel, b) driving a wedge having a vertex into the slit to crush a portion of the honeycomb panel, the crushed portion forming a hinge whereby the honeycomb panel can be folded, wherein an angle of the wedge is greater than 90 degrees and less than 120 degrees; and c) providing an adhesive material on the honeycomb panel to hold the honeycomb panel in a folded position.
Claim 18
Independent Claim
