(Cl. 154-44) My invention elates to improvements in lami nated structured and particularly to improve ments in such structures wherein a compressible fragile interior lamination is arranged between 5 two outer protective laminations and provided with spacers which prevent crushing of the into rior lamination, and securing devices which ex tend through the several laminations holding them together. to ’ An object is to provide such a structure with improved means to secure the several laminations together andvwhich means cooperates with the spacers to permit limited compression of the structure, providing a compact unitary structural assembly which may be piled or packaged for In the drawing the metal dash is indicated as Ill. My improved panel structm'e is indicated ' in assembly as it‘. It comprises what might be termed a foundation layer it with additional superimposed layers. This foundation layer is 5 formed of ‘material suitable for the interior’ trim _ of an automobile body at such, point. A material which has been found. suitable for this use is a composition ?ber board sold commercially under , the trade name of K B‘ board. This comprises 10 cellulose ?bers held together by an adhesive as phaltic compound. Such material isl moisture resistant. It is relatively dense and tough and it is thermoplastic so that it may be decoratively embossed or otherwise shaped in contour as destorage or shipment, quickly and readily assem sired.

For each tubular spacer element I provide a pair of cooperating split tubular sleeves or fer rules 22. These sleeves are secured to the outer protective laminations as shown in Figs. 2 and 3‘ and extend into opposite ends of the spacer ele ments when the several laminations are assem 10 bled together as shown. The sleeves are provided with ridges or corrugations which are adapted to , secure them to the outer laminations I4 and I8 and also to secure them frictionally in place within the spacer elements and with end ?anges 15 which overlie the outer layers l4 and 18. The combined length of the two sleeves within any‘ spacer element is less than the axial dimension of such spacer whereby limited axial compressi bility of the spacer is permitted before the two 20 ferrules are brought into engagement to- limit such compressibility. While the spacer‘ elements are compressible they are not compressible to the same extent that the insulation lamination I6 is compressible. 25 The insulation lamination is very easily com— pressed to a small fraction of, its normal thick ness while the permitted axial compressibility of these tubular spacers is relatively slight and increasingly resisted and the spacer elements are 30 resilient to return the outer walls of the lami support provided with apertures to receive the same the worker can see to align-the sleeve aper tures with the apertures through the support. Upon this alignment being accomplished the fas teners may then be inserted in place. As the expansible heads of the‘ fasteners are passed through the apertures within the support they expand su?iciently to engage the support to secure the panel thereto. This expansion is due to the inherent expansible tendency of the split spring fastener. The spacer elements are com pressed su?lciently to permit of this‘compression of the laminated panel against the support. The 15 split sleeves permit limited compression of the spacer elements while preventing undue com pression which might result from the.stacking or storing of a plurality of panels. Such undue compression if permitted might result in perma 20 nent densi?cation or compacting of the interior insulation layer as a'result of its thermoplastic. characteristic. ‘ _ In Fig. 4 is illustrated a» modi?ed form of con struction wherein the‘ sleeves‘of the securing de 25 vice which fastens the several laminations of the panel together do not extend ‘through the spacers.
