' MEANS FOR ATTACHING THERMOPLASTIC .SHEETS To OTHER MATERIALS Raerf S. flmes 014 u'MVIIIIIIIIIII I fIVVVVM Patented Jan. 21, 1947 MEANS Foa n'rraonma 'rnnnuoms'nc snnars 'ro ornna MATERIALS Robert S. Ames, Akron, Ohio, assignor to Goodyear Aircraft Corporation, Akron, Ohio, a corporation of Delaware J Application September 2, 1944, Serial No. 552.411
17 Claims. (Cl. 189-64) This invention relates to the attachment of "Plexiglas," a thermoplastic, and similar plastics to other materials, and, in particular, to such attachments which do not require bolts, rivets, or
'other fastening means passing through the Plexiglas surface.
Plexiglas, in sheet form, is used to a great extent for windows, and especially for hoods or canopies for airplanes, like navigator. domes,
noses, gun turrets, and the like; however, it may.
be used for any vehicle or for any wall which is to be transparent. Constructions of this nature hitherto in use have had the disadvantage that, frequently, unfavorable stresses are set up due to concentrated local forces or to forces not acting in the direction of the plane of the window surface. In other cases routing of the edges of the formed Plexiglas sheets is required for cementing thereto fastening ledges made of the same material, or for making their outer surface flush with said frame.
.It is the general object of this invention to avoid and overcome the foregoing and other difflculties of and objections to prior-art practices, and to provide fastening means whereby the Plexiglas is subjected only to forces which are directed substantially in surface.
Another object of this invention is to fit and to fasten transparent plastic into or around an opening flush with the outer surface of a vehicle structure without the need of cutting the edges of the plastic, thereby saving labor and expense.
Another object of this invention is to provide fastening means which uniformly tighten the plastic to its supporting frame without creating the direction of its.
bending stresses therein which might lead to crazing or cracking.
The aforesaid objects of the invention, and other objects which will become apparent as the description proceeds, are achieved by providing the fastening edges of the "Plexiglas or other plastic hood or panel, as the case may be, with a reinforcing ledge of suitable width and of the same kind of material which is directly cemented to the inside of the hood without the necessity of routing the edges. Into this reinforcing ledge, on the side to be cemented, notches are out. These are suitably spaced apart and take up the resiliently-supported fastening means which are secured outside the Plexiglas hood edge to the vehicle structure. A rubber or similar gasket inserted in the hood support and pressing against the edge of the hood serves as a weather seal.
For a better understanding of the invention,
reference should be had to the accompanying drawing, wherein Fig. 1 is a fragmentary crosssectional view of one embodiment of the invention taken on lines 1-1 of Fig. 6; Fig. 2 is a fragmentary side view of Fig. 1, looked at from the outside in the direction II-II; Fig. 3 is a horizontal cross-sectional view taken on line- III-III; Fig. 4 is a cross-sectional view taken on line IV-IV of Fig. 2; Fig. 5 is a horizontal cross-sectional view taken on line V--V of Fig. 4; and Fig. 6 is a fragmentary side elevational view of an airplane fuselage.
Although this construction is broadly applicable for Plexiglas coverings of any kind, it is especially adapted for the purpose of fastening aircraft hoods and hence it has been so illustrated and will be so described.
With specific reference to the form of the invention illustrated in the drawing, the numeral i indicates, as a whole, the frame on an airplane fuselage surrounding an opening, for instance, at the pilot seat, covered by a hood or canopy 2 made out of Plexiglas or similar thermoplastics. The frame I is formed by the outer skin 3 of the airplane to which is fastened by rivets 4, a reinforcing strip 5, which, together with the skin 3, forms a groove 5, and by the channelshaped part 1 attached to the inside of the skin. A rein-forcing angle 8, with one leg pointing downwardly, facing and spaced from the reinforcing strip 5, is attached, preferably by spot welds, to the channel I.
The hood 2 has cemented to its inside, substantially flush with the bottom, a reinforcing or fastening ledge l0, preferably of the same material as the hood, into which are cut notches Ii suitably spaced apart and facing the hood 2. Similar notches l2 are cut into the inside of the reinforcing strip 5. Into these notches are inserted tongues i 3 extending from a continuous grip molding H, made of longer or shorter adjoining length, under which is placed a rubber cushion l5, thereby uniformly distributing the hold-down pressure upon the hood and preventing objectionable stresses therein. A metalbacking strip i6 overlapped by the molding it covers the inside of the hood ledge l0 and extends into the space between the strip 5 and the angle 8. The rubber packing "inserted in the groove 6 provides a weather-seal between the hood and itssupporting frame, to which the hood is fastened by means of the tongues l3, and screws l8, which tie together the inner and outer portion of the frame.
out by placing the hood on the frame and then inserting the tongues of the grip moldings,
which may be advantageously used in lengths best suited for quick insertion of the tongues into the slots, which allow expansion of the hood due to changes ifitemperature. Whereas this invention is particularly suitable for fastening hoods made of thermoplastic material, like Plexiglas, any other material, either.
transparent or impervious to light, may be employed wherever the basic-features of this construction can be applied to advantage.
While, in accordance with the patent statutes, one known embodimentof the invention has been illustrated and described in detail, it is to be particularly understood that the invention is not limited thereto or thereby, but that the inventive scope is defined in the appended claims.
