De RiJJer ATTORNEV United States Patent 0 3,110,371 METALLEC STRUTURAL UNi'ES Ernst 5. De Ridder, Henrico County, Va., assignor to Reynolds Metals Qompany, Richmond, ya, a corporation of Delaware Continuation oi application der. No. 479,357, Nov. 24, 1954-. This application Sept. 3, H59, 52:. No. 338,321 10 Claims. (Cl. 189--3-t) The object of the present invention is to provide a metallic structural member adapted to be formed by extrusion and in which the ends are so formed that a plurality of the members may be interlocked, the characteristic of the formation being its provision of alternate fiat surface ribs and channels interlocked in such manner, as to a plurality of the members, to provide a strong watertight and moisture-resistant seal at each interlocking point, and with added pressure resistance.
The structural member of my invention is particularly adapted for use as flooring in vehicles such as trucks, railway cars, etc., and in lighter gauge it may be employed for siding, panels, roofing, and in other connections where a surface formed of a plurality of interlocked sections is required at low cost and with great facility in its application, together with the stated strong and effective seal at the areas of interlocking. When interlocked, the said members virtually form, in assembly, a unitary structure regardless of length and the number of members interlocked.
The invent-ion will be described with reference to the accompanying drawing, in which:
FIG. 1 is an isometric view showing three interlocked members in accordance with the invention, the righthand outermost member being broken awa FIG. 2. is an enlarged perspective view, partly broken away, showing the interlocked areas of two of the said members;
FIG. 3 is a view similar to FIG. 2 but illustrating the manner in which the interlocking is effected, and prior to bringing the two members down to the position or" FIG. 2;
FIG. 4 is a longitudinal section through the structure of FIG. 2 and an underlying support for the interlocked members, showing the use of a nut and bolt arrangement for connecting the members to the underlying support;
FIG. 5 is a longitudinal section through the interlocking area of HQ. 2, showing a modified provision of tying down the interlocked area of two members to the underlying support by a bolt and nut arrangement;
FIG. 6 is a longitudinal section through a modified form in which one of the members is provided with a sheet-like extension having transverse weakened areas or channels, enabling said section, when interlocked with an adjacent member or section, to be bent upwardly to serve as a base board or other inwardly planar area.
Referring to the drawing, I have shown in FIG. 1 three interlocked members which may be considered as flooring. From "left to right the said members are generally indicated by numerals l, 2 and 3 designated with brackets. The formation and interlocking of members 1 and Z is best shown in FIG. 6. Member fl is formed with an extension fix which is transversely weakened or channeled at a plurality of spaced points indicated at lxx, and this extension is planar at its top face. -t merges into a flat top r-ib 3 having at its edge a rounded nose 4, back of which is a rounded receiving recess for the rounded rib 5 of member 2. The nose 4 of member 1 merges with a channel extension having a flat base wall 6 and an upwardly extending leg '7. Upwardly extending leg 7 of member 1 is, at its top, formed with a rounded nose 8.
a eliorated Nov. 12, 1953 ice Member 2, at the interlocking area with member 1 is formed with a fiat topped hollow rib 9 having a rounded recess in its lower face to receive nose 8 of member 1. At this point of the interlock. member 2 is formed with a channel which closely fits the channel of my member 1 inwardly of the upwardly rising leg 7, and the said channel terminates with the rounded rib 5 which fits in the channel provided under the nose 4.
it will be understood that each of the members, having interlocking means at its ends, may be provided with as many intermediate ribs and channels as desired or permitted by the method of manufacture. It will be understood that while aluminum is a preferred metal, other metals may be employed, and that in some cases the members may be cast, and they may even be rolled sections intermediate the interlocking areas, for exam ple, and welded to the interlocking areas.
The interlocking area of member 3 is the same as that for member 1, as to one end thereof, and the same as member 2, as to the opposite end thereof.
Comparing FIG. 2 with PEG. 6, the difierence in PEG. 2 is simply that extending to the left of the interlocking area is a flat bottom channel merging into a fiat top rib, the latter shown as broken away. This rib will be completed by the normal width of its fiat top wall, its downward leg, and its continuation as a plurality of flat top ribs and channels as in member 2, FIG. 1. For this reason the same reference characters in PEG. 6 have been applied to FIG. 2 at the interlocking area of the latter.
FIG. 3 shows the manner in which the members are interlocked. With one member lying flat on its suitable support, one end of a second member having the outermost rib 5 will be raised and the rib 5 inserted under the nose 4 of the first member. Thereupon the second member is moved downwardly to the position of PEG. 2 and rib 8 will enter the channel provided under the hollow flat top rib 9 of the said second member, forming the tight double-wall channel interlock of FIG. 2.
As shown in FIG. 4 the interlocked members will be supported by one or more underlying supports it} and any suitable means attaching the members to said support may be employed. in FIG. 4 a bolt 11 is passed through member 9, with its head preferably countersunk in member 9. The shank of the bolt passes through the support lb and its threaded end receives a nut 12.
In FIG. 5 the extension 6x of base wall 6 is apertured to receive a bolt 13, and the latter passes through the support 16, receiving at its threaded end a nut 14. The number or" such bolts employed may be as desired for firm connection of the members to the support.
The invention is particularly applicable to refrigerated trucks and trailers which usually have a floor with many grooves thus securing sumcient air circulation below the freight. Many aluminum floor extrusions similar to corrugated sheet configurations have been developed and put in service. It has been found that these shapes are not completely watertight at the points where they are con nected together. As refrigerated trailers always have condensation, water fiows thr ugh these joints thus causing a lot of trouble with corrosion and making many costly repairs necessary. Many special floor extrusions with different joint designs have been put on the market, their water tightness depending more or less on sealing compounds which are helpful only for a short service period. Sealing compounds are not required in the present construction and the strength and resistance to shifting of the assembled members is improved.
It will be understood that the walls of the members are sufficiently flexible to interlock and yet spring into tight connection.
In the modification, FIG. 6, and in the preceding structures, the leg 7 may be formed with a normally horizontal extension 7x so that a bolt passed through openings such as 15 and into the underlying support will tie the interlock members together. Due to the flexibility of the interlocking members, the overlying members at the interlocks may be provi ed with minimum tolerance with respect to the channels in which they are received so as to require a certain pressure to shift these extrusions together and therefore securing such tight connection as to adequately resist lateral shifting.
This applica 'on is a continuation of my copending application, Serial No. 470,867, filed November 24, 1954, now abandoned.
