1 Claim. 1

The-present invention relates to plumbing lines and the like, and more particularly to a means for binding together and securing a number of parallel plumbing lines, conduit or the like.

Wherever a number of plumbing lines or the like: run closely parallel between equipment installations, as in aircraft hydraulic systems for example, it is usually necessary to bind and securer closely adjacent lines together at certain points between structural supports in order to eliminate vibration, reduce frictional wear, and occasionally to provide additional support.

One of the objects of the present invention is to provide an economical line binder of lightweight that will meet Army and Navy (AN) standards and which will also be useful in other applications. Cord, tape and rawhide bindings, for example, are not iireproof and are not approved.

Brieily, one form the present invention may take is that of a longitudinal strip of lightweight bendable metal of predetermined length and shape. The central portion of the longitudinal strip is cut away forming an inner longitudinal tongue element having one end free and being joined to the outer strip at the other end only. Thus divided, the outer and inner elements are wrapped and woven alternately progressively around a number of cylindrical members parallel to each other and fastened by a lockwire or other means. The number of members to be bound, and the diameters thereof, determines the length of the longitudinal binder elements.

The present invention will be more clearly understood by referring to the accompanying drawings where:

Figure 1 is a flat plan View of one preferred form of the present invention.

Figure 2 is a perspective view of the binder shown in Figure l applied to a number of cylindrical members using a safety wire fastener.

Figure 3 is a perspective View of the binder shown in Figure 1 applied to a number of cylindrical members using a locknut and bolt to fasten the binder in place.

In Figure 1, a longitudinal strap Il! of nonresilient metal, such as .016 annealed stainless steel for example, is symmetrically contoured and cut away in the center to form an inner longitudinal element I I, surrounded by an outer longitudinal element I2, having only one end free. By calculating the diameters of the members to be bound and secured, the length of the binder can be accurately predetermined to exactly fit any specic number of cylindrical members of (Cl. 24S-'68) 2 specio diameters; The tab" ends I3 and Ifd di the inner and outer longitudinal elements I-I and I2, respectively, areV preferablyrounded as" shown; and each' are respectively provided with a hole I5 and Iii positioned to alignv and accommodate a fastener (not shown in Figure 1). The outer longitudinal element I2 is also provided with a transverse slot Il slightly wider than the inner longitudinal element II, and is positioned inwardly ofthe hole I `inthe tab end I4 of the outer element I2. Theend opposite thetab ends ofthe' longitudinal elements will be known-as'th basal end I9 of the strap I0.

In use, the basal end I9 of the strap IU is curved around the periphery of the outermost member 20a of a group of tubular members 20, as shown in Figure 2 for example, with the longitudinal elements pointed downwardly. The outer element I2 is brought outwardly and upwardly behind the basal end IS which is in contact with the outermost tubular member 26a, bending the outer element tangent to the inner element II. A safety wire 2l can be passed through the radius formed at the bend, to be fastened at the completion of the wrapping operation. The outer element I2 is then wrapped around the top periphery of the outermost tubular member 20a and passed downwardly between the outermost member 20a and the next parallelmember 20h and wrapped around the bottom periphery thereof, and is then brought upwardly between the second member 20h and the third parallel member 20c, repeating the progressive alternate wrapping operation for as many members as are t0 be bound and secured. The inner element. wrapped reversely of the outer element, is brought under the first member 2da and wrapped around the bottom periphery thereof, progressively alternately wrapping each parallel member 20o and 20c in turn until the tab ends I3 and i4 of each longitudinal element I I and I2 meet on the opposite side of the group of wrapped members 20. The tab end I3 of the inner element II is then passed through the transverse slot II and bent downwardly at a substantially right angle thereto, bringing the holes I5 and IE into alignment to receive the fasteningwire 2i. Thus it can be seen that the device of the present invention,

Vin addition to providing a strong lightweight line binder which is reproof, effectively pads one line from its neighboring line so that friction therebetween is prevented.

Where it is desirable to designate line binders for re-use, the tab ends I3 and Ifl of the longitudinal elements II and I2 can be preformed to right angles, omitting the slot i1, as shown in Figure 3. The right angled tab ends I3 and I4, of the inner and outer elements Il and I2 respectively, are diametrically opposed and brought into close contact aligning the holes l5 and i6, and a bolt 24 passed therethrough to receive a locknut 25.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modication in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacricing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise a preferred form of putting the invention into eiect, and the invention is, therefore, claimed in any of its forms or modifications Within the legitimate and valid scope of the appended claim.

What is claimed is:

A device for binding together a plurality of parallel longitudinal members; comprising a unitary length of exible metal strip having a lengthwise longitudinal strip cut away from the center thereof to dene an intermediate wrapping element joined at one end only thereof to the remaining portion of said strip which forms an outer wrapping element extending completely around the edge of said intermediate wrapping element, a narrow slot transversely positioned in the end of said outer wrapping element adjacent the free end of said intermediate Wrapping elel a locking means.
