(01. 290-44) Figure 2 is a partial section therethrough, This invention relates to automobile panels and the like, such for example as are used in automobile doors and bodies, and is illustrated as embodied in an automobile door having novel inexpensive but very strongymeans for attaching ‘ a panel of ?berboard to'a sheet-metal backing. . An object of the invention is to provide inex pensive fastening means of great strength which can be manipulated with great rapidity, thereby 10 lessening the cost while at the same time increas ing the strength of the joint. To this end, the joint includes a tape of wires secured at intervals to the metal backing, pref erably by spot-welding, and with which are in 15 terlocked fastenings such as staples, headed fas tenings of the type of single or double-pointed tacks, or the like, all of which are adapted to be showing the joint between the non-metallic ma terial and the metallic backing; Figure 3 is a view on an enlarged scale showing the tape spot-welded at intervals to the metallic 5 backing; . > ‘ Figures 4, 5, 6, and "I are partial sections on an enlarged scale, lengthwise of the joint; showing the use of different types of fastenings; and Figures ‘8 and 9 are respectively perspective and 10 ' elevational views on a still more enlarged scale of the format fastening used in Figure 7. Figures 1 and 2 illustrate a hollow panel for an automobile door I0, having an outer sheet metal face I! and an angle-section stamped sheet- 15 metal frame or backing I4 of any desired form. The present invention relates to the means for attaching to such a structure a sheet of ?berboard it used as an interior ?nish, or other sheet clinched by being driven through the wire tape against the metal behind it. 20 material, usually of a non-metallic character. Other desirable fastenings may, comprise heli 20 The novel joint includes‘a tape I8 of wires, cally formed, pointed wires, or similar devices, which may be screwed through the panel and, in preferably braided alternately over and under effect, threadedly interlocked with the tape. Or, ,each other diagonally ‘of the tape and each ex if desired, fastenings may be inserted through the tending the full length of the tape, the tape be 25 tape from the reverse side beforeit is secured to the metal backing, and, after it is so secured, clinched on the outer face of the panel. For the wire tape I prefer to use a braid of wires carried alternately over and under each 30 other diagonally of the tape for the full length of the tape. This gives a very strong joint, since it insures that the particular wire which inter looks with a given fastening will itself be secured - directly to the backing. Also this construction 35 avoids any considerable open space in the tape, since the wires are substantially in engagement with each other, while yet the points of the fas tenings easily ?nd their way between adjacent wires because of the relatively great distance be , 50 55 the backing M, as indicated at 20. Since the different wires all extend at times into the mar gins of the tape, it is almost certain that each '30 wire will be welded at several intermediate points to the backing M, as well as at the ends of the tape. a - Various types of fastenings may be used to secure the material IGAto the tape l8, but I prefer 35 to use fastenings which are readily clinched against the tape l8 by being driven against the metal backing 14. As examples, Figures 4 and 5 illustrate the use of staples or stitches 22 and of headed double-pointed tacks 24. The points of 40 by the other wires. Any de?ection of the points these fastenings readily ?nd their way between of the fastenings merely aids in clinching them, , the interbraided wires of the tape, even if de as they readily ?nd their way between the wires ?ected by engagement with the wires. Moreover ‘ there is no possibility of some of the fastenings even if they do not go straight. The above and other objects and features of failing to engage and interlock with the wires, 45 asthere is no substantial space anywhere be the invention, including various novel combina tween the wires. _ 7 tions of parts and desirable particular construc Another desirable method of securing the panel tions, will be apparent from the following de scription of the illustrative embodiment shown in is illustrated in Figure 6 in which are shown staples or stitches 26 the prongs of which are in- 50 ‘ the accompanying drawing, in which: Figure 1 is a side elevation of a panel for an serted through the tape l8 from the side next to the metal backing it prior to fastening the tape automobile door, with part of an overlying?n on the backing so that the body of the staple lies ish sheet of non-metallic material such as ?ber board or the like broken away at one side to show between the backing and the tape. After the tape is secured, the panel it is forced over the 55 the metal backing; 40 tween the points at which any given wire is held 45 ing welded or otherwise secured at its ends to the 25 backing l4. Between its ends, at intervals, the tape may be spot-welded at its margins only to 2 araaess prongsoi the staples and the prcngs are clinched on the outer face of the panel. - Figures 7-9 illustrate still another fastening 28 comprising a pointed wire which may be doubled back on itself, as at 36, to form a head and be formed with one or more helical or spiral coils 32 adapted to be'screwed through the panel i6, and, in eil'ect, be threadedly interlocked with the wires of the tape iii. 10 While particular constructions have been de scribed above, it is not my intention to limit the scope oi the'invention byv that description, or otherwise than by the terms of the appended claims. 15 I claim: ' ' .
