形で強度の高いものにした例である。(Example)) This will be explained with reference to the illustrated example. The ones in Figures 1 to 4 are examples in which the entire auxiliary device is made of one piece.
Spacer portions having straight protrusions 4, 4 are formed at both ends so as to extend the rod 1 as it is. In the example shown in FIG. 1, a fitting body 2 is provided inwardly in an arc shape by a required distance D from its tip, and a binding branch frame 6 is provided at a right angle on the side. C indicates the center of the fitted body 2. Figure 2 is the rod 1 of Figure 1.
A second fitting body 5 and a branch frame 6 are also provided on the opposite side of the fitting body 5, and the spacing between the tips of the protrusions of both fitting bodies 2 and 5 is made equal to two types, a specified minimum spacing D 1 and a general spacing D 2 . ,
FIG. 3 shows a structure in which a triangular spacer part 3 and a head 8 are provided at the end of the rod 1, a protrusion 4 is provided at the center of the rod, and the protrusion 4 and the branch frame 6 are connected with diagonal members 10 and integrated. This is an example of high strength.
