Turnbuckle

The innovation concerns a turnbuckle with two coaxial screws screwed into threaded holes in a housing Threaded bolts, one of which has a right-hand thread and the other has a left-hand thread, and whose outward-facing heads are each designed as an eye.

The known turnbuckles have a housing with two coaxial threaded holes, one of which is threaded hole consists of a right-hand thread and the other consists of a left-hand thread. There are threaded bolts in these threaded holes screwed in, each with a counter knife is screwed on.

This known rigging screw has a number of disadvantages. It is difficult or impossible to get one using the rigging screw to reproduce the optimal setting of the shrouds, as marking options not with regard to the screw-in depth of the threaded bolts

or are difficult to achieve. This also follows di «Difficulty in tensioning the two shrouds equally, as this depends on an even Screw-in depth of both threaded bolts. There is also the disadvantage that the setting of the Shroud tensioner can change, for example when Lock the lock nuts against the housing or if the lock has loosened.

There is therefore the task of designing the turnbuckle so that the shrouds are uniform and reproducible can be tensioned. The aim is also to ensure that once the position has been set, it does not change.

This task is solved with the features of the claim:

1. Advantageous refinements can be found in the subclaims. i

An exemplary embodiment is shown in the drawing. Show it:

Fig. 1 is a plan view of the turnbuckle;

I Fig. 2 is a side view of the rigging screw and |

the upper part of which along the line III-III in FIG is cut. ;

The turnbuckle has a housing 1, which with several mounting holes 2 not shown in detail is provided. Mounted in the housing 1 is a Screw 3, which is connected to a handwheel 4.

The worm 3 is in engagement with a worm wheel 5. This worm wheel 5 forms the external toothing In the middle part of a threaded bushing 6. This threaded bushing 6 has two threaded bores 7, 8 which run coaxially one behind the other, one of which is threaded bores fine right-hand thread and the other consists of a left-hand thread.

The sleeve 6 is rotatably mounted on the housing 1 by means of two arms 9, 10. The worm wheel 5 is located here • lit his outer shoulders against the arms 9. 10.

There is a threaded bolt in each of the threaded bores 7, 8 11.12 screwed in. One threaded bolt has a right-hand thread and the other a left-hand thread. The housing 1 is provided with two further outer arms 13,14, which the threaded bolts 11,12 non-rotatably, however axially displaced! i hold. For this purpose there are threaded bolts 11, 12 with two flats 15, 16 versehe-n and the holes 17 of the further arms 13,14, through which the threaded bolts 11, 12 are guided, have a cross-sectional shape that corresponds thereto.

The flattened areas can be provided with notches, which allow a reproducible setting of the screw-in depth In addition, 4 markings can be provided on the handwheel.

If the worm 3 is set in rotation by means of the handwheel 4, the sleeve 6 is rotated as a result, whereby the effect is that the threaded bolts 11, 12 are on both sides move evenly outwards or inwards.
