SLIP GUIDE FOR BINDING STRAPS v Filed Feb. 12, 1963 //\/1/& N THE George CAno'erson 0 IF w. x h.

United States Patent 3,152,693 SLIP GUIDE FOR BINDING STRAPS George C. Anderson, Portland, 0reg., assignor to Anderson Die and Manufacturing Co., Portland, Oreg.

Filed Feb. 12, 1963, Ser. No. 257,918 1 Claim. (Cl. 206-60) This invention relates generally to bundle or crate binding straps and more particularly to slip guides tor such straps as shown in my US. Patent, Des. 192,385, issued Mar. 13, 1962.

The present invention is a generally improved form of the slip guide illustrated in US. Patent, Des. 192,385.

Like the binding strap slip guide of my previous patent, above noted, the present slip guide is molded of a plastic material slippery in feeling when in contact with the common form of steel binding strap with which it is used and relatively variable in rigidity or in flexibility depending on the thickness and the cross section area of the plastic piece being bent.

Generally the slip guide is formed of a single piece of material having a pair of internally planar legs extending something less than 90 degrees one from the other. As here shown each of the legs taper in thickness from its angle of union with the other to a somewhat reduced thickness at its outer edge.

In US. Patent Des. 192,385 it is noted that nothing is provided to hold the guide to a strap but when the strap is held around the bundle or the crate and the guides are positioned under the strap at the corners of the bundle or crate, the strap can be tightened a small amount to hold the guides in place While the strap tightening procedure is completed.

However in providing large quantities of these slip guides to the trade, I have encountered an increasing demand for some method or means for attaching the slip guide slidably along the strap so the guide will not be dropped during its application.

The present invention provides an improved slip guide for binding straps wherein the slip guide is formed to include means for attaching the slip guide slidably along the strap and wherein said means requires only a simple manual method without other tools for attaching the means.

To show a preferred form of the improved slip guide for binding straps of this invention FIG. 1 of the accompanying drawing shows a view in perspective [of a fragmental bundle 12 of plywood sheets, bound around one end, typically, by a steel strap 13 having one of the improved slip guides 14 of the present improved type under the strap at each corner of the bundle and the strap held in tension around the bundle by a deformed strap anchor 18.

FIG. 2 is a top plan view of one of the legs of the improved slip guide.

FIG. 3 is a center line section of one of the improved slip guides 14 as viewed along the line 33 of FIG. 2.

FIG. 4 is an offset sectional view of one of the improved slip guides 14 as viewed along the line 4-4 of FIG. 2.

FIG. 5 is a sectional view as seen perpendicularly to one of the legs of a slip guide 14 as viewed along the line 5-5 of FIG. 2, and showing in section the flexible hinges 16 with which the tabs are held within the windows 17 of the legs of the slip guides 14 to secure the slip guides slidably along the strap 13.

3,152,693 Patented Oct. 13, 1964 "ice FIG. 6 is a sectional view as seen perpendicularly to one of the legs of a slip guide 14 as viewed along the line 6-6 of FIG. 2 and showing the pair of tabs 15 of one window 17 lifted about their hinges 16 away from the window 17 to start the assembly of the slip guide 14 onto the strap 13.

FIG. 7 is a sectional view as seen perpendicularly to one of the legs of a slip guide 14 as viewed along the line 77 of FIG. 2 and showing the pair of tabs 15 of one window 17 resiliently holding the slip guide 14 slidably positioned along a strap 13 to hold the slip guide 14 over a corner of bundle 12 as strap 13 is cinched tightly in tension over the bundle and secured in place by deformed strap anchor 18.

FIG. 8 is a view in side elevation as viewed along line 88 of FIG. 1 to show the ends of strap 13 secured in tension about bundle 12 by deformed strap anchor 18.

The outer faces of the two legs will be formed with laterally spaced, raised rib elements 21 thereon to position the strap relative to the guide and with transversely extending, longitudinally spaced, raised rib elements 19 and 20 adjacent the outer edges of the legs and adjacent the intersections of the legs, respectively, to tension the strap.

Although the exact dimensions of the elements illustrated in the several figures of the drawing are not essential to the invention it might be interesting to note that in the size shown in FIGS. 2 to 7, the mild steel strap 13 is about one and one-quarter inches wide and one fiftieth of an inch thick; the right angular length of each of the legs of guide 14 is about two inches and the length of each of the guides 14 perpendicular to the strap tapers from about two and three quarters inches at the angular junction of the two legs to about two and one-quarter inches at the outer end of each leg. The window 17 in each leg of the slip guide 14 is about five-eighths inch wide in the direction of the strap and one and one-half inches long across the strap. Each of the tabs 15 is about ninesixteenths inch wide and extends into the window 17 about seven-sixteenths of an inch. As the tabs 15 are shown in FIG. 5, their full thickness is the same as that of the frame surrounding the Window 17 while the thickness of binge 16 of tabs 15 is reduced to one-half that of the frame surrounding the window 17.

The strap 13 and its anchor 13 are prior art and no part of this invention which includes only the improved slip guide formed with some practical equivalent of the windows 17 and the specially formed tabs 15 with their hinges 16.

Having thus recited one of the objects of this invention, illustrated and described a preferred form in which the invention may be practiced and described its operation, I claim:

An improved form of slip guide for a flat metal binding strap, said slip guide comprising a single piece of molded solid plastic material resiliently bendable along a flat section in proportion to the thickness of the section, said slip guide being formed of a pair of internally planar legs each extending substantially 9O degress one from the other with the stiffness of said legs along their junction one with the other being sufficient to maintain said junction of the internal faces of said legs at substantially said degrees, the outer faces of each of the two legs of said slip guide including laterally spaced means to position said strap normal to said junction and means spaced parallel to said junction to support said strap on each of said legs both at said junction thereof and at their ends opposite said junction, each of said legs between its said spaced means for positioning said strap and between it said spaced means for supporting said strapfbeing formed with a pair of laterally spaced tabs, each of said tabs including hinge means along its outer edge normal to said junction of said two legs, the material of each of said legs between said tabs being omitted to fiorm a window, whereby each of said tabs may be rotated on its said hinge away from its said position over said window to allow said strap to be moved over said Window under said tab and said tab will be resiliently held slidingly over said strap until said strap can be fixed by tension into its permanent position References Cited in the file of this patent UNITED STATES PATENTS Anderson Mar. 13, 1962 Beisel Jan. 19, 1904 Way Apr. 16, 1940 Pagel July 28, 1942 Symmonds, Jr. Jan. 15, 1963 Brown Jan. 22, 1964 FOREIGN PATENTS France J an. 26, 1933
