■ Tensioning sheet for lashing down one with an eyelet

Strap (II) -

To lash TJm tensioning straps tightly, special tensioning devices are often used, as the _; Handicraft is not sufficient to achieve a sufficiently high preload for this purpose * The clamping devices are based on a lever transmission, through which a small introduced hand force is converted into a large clamping force. A hiring concerns a particularly simple one for this purpose: serving hooks, for a. tightening strap provided with an eyelet.

The tension hook according to the furnace has the characteristic "that a straight piece serving as a lever arm is followed by a double U-shaped crank" ^:.

At the end facing away from the bend: the straight piece can be angular, bent. The deflection is used to fix the clamping band in DER clamping position, but also forms a handle ⁷ ·. . . ^;

The .äußere end of the "last bend"is't- appropriate vertical: ^{abgekröpft-:} .ebenso also the end of the angled bend ^"-:,: ■";. ..: - ■; ^....:. .. .- ■

The innovation is based on the one shown in the drawing Embodiment explained * It show:

Figure 1 the tension hook,

Figure 2 shows the same tension hook with an inserted tape

before the start of the clamping process. Figure 3 shows an intermediate position during the clamping process

and
Figure 4 tension hook and strap in the tensioned position *

The clamping hook 1, made from a piece of round steel, has a straight piece 2 acting as a lever arm and the double-shaped bend 3, 4, 5. At the end facing away from the bend, the clamping hook is bent at an angle at 6. The bend 6 and the outer arm 5 of the second bend are bent vertically at 7 and ■ 8-. The cranks should prevent the tape from sliding off.

The task of the clamping hook is to pull the two strands 9 and 10 of the clamping hook firmly against each other. The strand 9 ends in an eyelet 11, while the end 12 of the strand 10 is free »

The eyelet 11 is over the bend 6. on the straight piece pushed so that it includes the arm 3 of the first bend. The strand 9 is' dsrfcreH "below the turn 6 #.:

The end 12 of the strand 10 is under the arms 5 and 4 the second bend over arm 4 and under the arm 5 placed.

The end 12 is first made by hand as far as possible tightened so that strand 9 is also slightly pretensioned,

Now the clamping hook is turned over in the direction of arrow 13 (! Figure 3) until it finally reaches the clamping position naoh ligur 4 occupies. Turn 6 is under the Strand 10 pushed * The static friction between the end of the belt 12 and the strand 10 is so great that the end of the belt cannot slide out. The tension is completely firm and sure"

To release the tension, the tension hook is returned to the starting position moved to ligur 2 *
