Tension hook-for Eest lashing an eyeletless strap

In many cases, simple hand strength is not enough to properly lash a strap. Rather, you need a clamping device which - due to a correspondingly large leverage ratio. converts the relatively small force introduced into a large clamping force. ! Inflation concerns a serving this purpose tensioning hook "particularly simple lorm, _and: namely for ösenlose bands, so for bands that are zusammengezurrt with free ends * The clamping hooks gemäß.der innovation is characterized by two pairs of clamping shafts, one of which in a straight piece serving as a lever arm passes over.

In order to prevent the strap from slipping off the tensioning hook when lashing with plagues, it is advisable to crimp the outer tensioning shaft vertically at the end. ■. .:.,

For locking the clamping hook in the clamping division -can -in particular the piece serving as a lever arm.

be bent at an angle. The bend then forms a handle at the same time. The turn can also be vertical Direction to be cranked *

The innovation is based on the one shown in the drawing Embodiment explained, It show s

Figure 1 shows the tension hook with a thinly drawn tension band before the start of lashing,

Figure 2 shows the hook and the position of the tape after first part of the clamping process,

Figure 3 tension hook and strap in the lashed state,

The tension hook 1 is bent from a piece of round steel and has as a feature the two expansion shafts 2, 2 'and. 3.3 'on, - which are made by crimping the round steel are. The arm 3 'of the expansion shaft pair 3, 3' goes into a straight piece 4- over which the lever arm of the tensioning hook 1 forms. 5 is a bend of the straight piece 4, 6 and are rectified bends. -

The task of this tensioning hook. Is - to lash a strap, one side of which is 8 and the other side of which is denoted by 9. The two ends are marked with 10-unä'Tt *

The strand 8 is passed under the crosspiece 5, placed over the tensioning shaft 3.3 * and the belt end IO between the arms 3.3 * stuck upwards so that it is below the strand 8 rests on the arm 3 '.

The strand 9 is placed from below under the arms 2, 2 *, with its end 11 passed over the arm 2 ^f and the end placed under the arm 2 under the strand 9 »

The two ends of the strap 10 and 11 are hand-tightened as much as possible. Then the clamping hook 1 is grasped on the crosspiece 5 and swiveled out in the direction of the arrow 13 shown in FIG. The first plane adjacent clamping shaft pairs are erected during this movement, as shown in "! Figure 2 is visible. Upon further pivoting of the lever arm 4 of the clamping finally takes hook 1, the position shown in I ¹ IgUr 3, where he pushed under the strand 9 so that the crank 7 prevents the tape from sliding off * The tape is now taut, and the very strong friction prevents the tape ends 10, 11 from being pulled out.

To release, the clamping hook is returned to the position shown in FIG Swiveled back position shown.
