This invention relates to an improved method of securing a rod or rods to a supporting structure and to apparratus constructed by said method.
The present art teaches the securing of a rod to a supporting structure by various means and for a variety of purposes. For example, in the fabrication of certain types of antennas, the need exists for placing antenna elements or rods perpendicular to the supporting structure or mast.
This is done by fabricating a hole in the element or rod and fabricating another hole in the mast or support ing structure. The rod can now be secured to the supporting structure or mast by conventional means, as a screw, bolt or rivet. The disadvantages of this technique are apparent. The strength of the rod is greatly impaired due to the resulting removal of material caused by the fabrication of the hole in the rod. Another disadvantage is the distortion of the rod if too much pressure is exerted by the screw, bolt or rivet. Still another disadvantage is that, if too little pressure is applied via the screw, bolt or rivet, the rod will have a tendency to rotate with respect to the supporting structure. In order to compensate for some of the above disadvantages, additional means are presently employed. Such means require additional parts, for example, various clamping arrangements, to secure the rod. While such clamping devices supply the necessary support, the additional parts, as in any manufacturing process, require fabrication and hence increase the cost of the final product. The additional parts also require additional steps thereby lengthening the manufacturing process.
Accordingly it is another object of this invention to provide an improved method of securing a rod to a supporting structure.
It is a further object to provide a method of the type described which does not substantially decrease the strength of the rod.
It is a still further object to provide a method of fastening a rod to a supporting structure by the use of a minimum number of parts, thereby reducing cost and decreasing manufacturing time.
Patented Feb. 25, 1969 It is a still further object to provide a method of the type described which eliminates the possibility of rotation of the rod with respect to the supporting structure.
One embodiment of the present invention entails a method of securing a rod to a supporting structure comprising the steps of forming a hole in said supporting structure so that the structure material is flared in a direction transverse to the supporting structure at the margin of the hole, inserting the rod into the hole and deforming the rod and said flared material by the application of a force transverse to said flared material and rod thereby locking the rod to the supporting structure.
The invention will be described in detail with reference to the accompanying drawing, in which:

FIG. 13 is an end view of a rod and supporting structure inserted and held in a representative jig or fixture.
In the several figures like parts are indicated by similar reference characters.
Referring to FIGURE 1, a hollow, rectangular, elongated supporting structure 1 is shown. The structure 1 is formed with a longitudinal passage 2, with holes 3, 4 and 5 appearing on the top surface and holes 6, '7 and 8 which are in line with holes 3, 4 and 5, respectively, appearing on the bottom surface. The structure 1 may be made of metal, for example, aluminum, or a desired non-metal material. In the specific embodiment illustrated in FIG. 1, the supporting structure 1 is about six inches long with a height and width of about 4 inch. In other embodiments the length might be several feet, fifteen feet for example, and, assuming the support to be a hollow square, the height and width might be one foot. in general, the dimensions are such that there is restricted access to the interior of the supporting structure. In FIG. 2 the numerals 9 and 10 indicate collars surrounding the holes 3 and 6. The collars 9 and 10 can be fabricated, from the supporting structure material 1, during the hole forming process; by conventional techniques, such as shaping, flaring or extruding. A method of achieving this is to use a hybrid tool configuration where the lower portion of the tool consists of a conventional drill bit and the upper portion consists of a cone-like section such that the diameter gradually increases in a direction towards the top of the tool. With said tool, after the hole is drilled by the drill-like portion; the cone-like portion of the tool is forced through the hole thereby forming a collar or flaring of the structure material. Other methods for producing the holes with collars or flaring are well known in the field and any such method is acceptable.
'In FIG. 3 there is shown a rod 11 inserted into the holes 3 and 6, the flared or extruded material forming the collars 9 and surrounding the rod 11. The rod 11 can be formed of rolled metal formed into a tube-like configuration or can be made of any other suitable material. A U-shaped elongated member 12 is shown in FIG. 4. Near the end of the member 12, a head or die surface 13 is provided at the two ends of the U. The dimension represented by reference 14-, designates the dimension from the outer most point on the die surface -13 to the back wall of the member 12. This dimension 14 is made somewhat longer than the distance between the collar 9 (and the collar 10) within the support structure 1 and the adjacent wall of said support structure. The die surface 13 of the U-shaped member 12 is made of a material harder than that of the support structure 1, to prevent excessive wear during the herein described method.
A form of the method will be described in connection with FIG. 7. An additional rod is shown inserted through the holes 4 and 7 on the structure; and a further rod 16 is shown inserted through the holes 5 and 8 on the structure 1. The member 12 of FIG. 4 is inserted in the longitudinal cavity 2 of the support structure 1. As the member 12 is forced through the cavity 2 in the direction indicated by the arrow the progress of the member 12 is hampered first by the engaging of the collars or flaring surrounding the rods 15 and 16 with the beads or die surfaces 13 of the U-shaped member 12 and then by the engaging of the beads 13 with the collars 9 and 10 which surround rod 11. By forcing the U-shaped member 12 through the cavity 2 by suitable means, not shown, the die surfaces 13 are made to exert a force transverse to the collars. Hydraulic, air or other force exerting means can be employed. Referring to collars 9 and 10, for example, the head or die surfaces 13 force the engaged area of the collars 9 and 10 inwardly, creating a similar indentation upon the rod 11. By this means the rod 11 is locked in its position with the supporting structure 1. This step in the operation is shown in FIG. 5.
From this it can be easily visualized that the member 12 in conjunction with its die surfaces 13 performs the same operation upon each rod 15, 16 and associated collars as it does on rod 11 and collars 9 and 10 as the member 12 is forced through the longitudinal cavity 2 of the support member 1. When the U-shaped member 12 is forced past all the collars and rods, each rod will be locked in its position within the support structure 1. The member 12 can be easily pulled out from either end as the indentation formed will allow clearance of the head -or die surface. It is also clear that the same U-shaped member 12 inverted, or another suitable member will perform the identical operation upon the opposite side of the collar by moving the member through the longitudinal cavity 2 with its outer Wall against the opposite wall of the supporting structure 1.
FIG. 11 illustrates a fork-like member 17 that will cause both sides of the collars around the respective holes 3 through 8 to be indented into the rods as the member FIGS. 8 and 9 show configurations that will lock the rod in the supporting structure by slightly different variations of the same method. If reference is made to FIG. 10 there is shown a perspective view of a plurality of rods in a supporting structure 1 where the collars 9 and 10 are formed by a similar process, as hereinbefore described, but on the outside of the parallel surfaces of the supporting structure 1. The support structure 1, may be solid or hollow for this operation. Here the U-shaped member 12 having die surfaces 13 passes over the support structure and in doing so exerts a force upon each collar and rod, thereby indenting such combination exactly as in the former case, causing said rods to be locked in said supporting structure. The final composite structure produced by this variation in method is shown in FIG. 8. The identations referenced as 18, firmly lock the rod in the support structure.
It should be noted that the previously described operations require a suitable jig or fixture to keep the assembly, consisting of the support structure and rods, secure and properly oriented during the application of force by the member having a die shaped surface. 'FIG. 13 shows a supporting structure 1, and rod 11, secured in position within a representative fixture or jig 19. The fixture 19 r can be firmly secured to a table or other body, not shown.
The supporting structure 1 is held in position by the two clamp-like structures designated as 21. These in turn can be positioned by means of the adjustable bolt arrangements 22. The assembly consisting of elements 21 and 22 and the side wall of the fixture constitutes a vise-like configuration.
It can be seen that the jig or fixture 19, although only a typical representation, can accommodate a member having die surfaces, such as the member shown in FIGS. 4, 7, 1O, 11 or 12, and consequently may act upon the collars 9 and 10 whether they are as shown in FIGS. 9 and 13 or are as shown in FIGS. 2 and 8.
While the diagrams show rectangular supporting structures it is clear that the support structure may take any other desired shape, such as square, hexagonal, oval, round or even irregular as required. The member having a die shaped surface will preferably be given a corresponding shape as to enable it to exert the required force. It is also clear that a member could be so devised as to perform an operation resulting in a composite struc- ,ture as represented in FIG. 9. This can be done with a member having characteristics of both the member shown in FIG. 7 and the member shown in FIG. 10. If reference is made of FIG. 12, the member 25 shown, will perform the operation resulting in the composite structure shown in FIG. 9. It is also clear that the holes fabricated in the support structure can take on any irregular shape corresponding to any type of rod to be inserted in such holes.
A feature of applicants invention is that no parts other than the rod and support structure itself are required to firmly lock the rod on the support structure. No rivets, clamps, or other means are needed. The invention is particularly useful in applications where a large number of rods are to be supported. In the past, each rod had to be secured in turn so that each rod required a separate, individual operation involving a number of different steps. By the present invention, a plurality of rods can be substantially simultaneously locked to a support structure by a single action, namely, the movement of the die member. Further, since it is not necessary to drill holes in the rods, or otherwise remove surface portions of the rods, the rods are not structurally weakened.

(a) forming holes through each parallel surface of said support structure at specified lengths along each surface with said structure material being flared in a direction transverse to the support structure at the edge of each hole, such that said flared material forms a collar on the outside of said support structure around each hole on each of said parallel surfaces,
(b) inserting said rods in said holes such that said rods pass through and extend from each surface of said supporting structure,
(c) inserting said combination of rods and support structure in a suitable jig or fixture to hold said combination rigid and properly oriented, and
(d) passing a member having a die surface over said support structure in such a manner that said die surface indents a portion of said flared material at each of said holes forcing said flared material into said respective rods, whereby said rods are locked in said supporting structure.
