Turnbuckle, especially turnbuckle

The invention relates to a turnbuckle, in particular one Turnbuckle, with two, - one external connecting link each having clamping sleeves, the inner ends of which are provided with one half with real and one left-hand thread Pick up bolts, at the longitudinal center of which a cross-sectionally U-shaped double lever is mounted, which when folding Flat-edged clamping sleeves engages and prevents twisting secures »

The known such turnbuckles (DT-PS 288 619) are always advantageously applicable when one rope end is connected to both ends of the turnbuckle. Turnbuckles However, they are also required in cases where a rope or wire end is only connected to one end of the turnbuckle is, while the other end of the turnbuckle on one

The bracket fixed to the body is slidably arranged. A special Such application example is the rigging screw which is attached to one end verrutschbar on a fixed to the hull putting _o In an often necessary in particular in Eegattarennen .Modification the sail mast tilt the turnbuckle to the bracket-like puttings must under tensile load in adaptation to the new mast orientation slip. In practice, however, it has been shown that the turnbuckles, which are still mostly under high tensile load, get stuck on the putting or tilt and do not automatically slip into the position corresponding to the new mast alignment, which results in high bending stress on the turnbuckle and this up can be deformed to uselessness »

The invention is based on the object of creating a turnbuckle that can be used in particular as a turnbuckle, _{or the like}

Based on a turnbuckle of the type mentioned, this object is achieved according to the invention in that at least one connecting member of the turnbuckle is articulated with its associated clamping sleeve is connected »Advantageously, the connecting member consists of a U-shaped bent Sheet steel strips, in whose U-deep star the convex head one passed through the U-bottom with play, on the

Adapter sleeve rigidly attached pin lies and between the legs of which a pin is releasably attached.

The turnbuckle according to the invention is practical, like in-depth Tests have shown, especially as a rigging screw, as it is between the one attacking the putting The connecting member and the joint provided for the clamping sleeve enables the turnbuckle to pivot relative to the putting, even if the connecting link and the putting maintain their relative position unchanged. In particular is but the risk of tilting between connecting member and putting is prevented, since the turnbuckle according to the invention connected to the putting in the manner of a universal joint is, as will be explained in more detail below.

Finally, according to the invention, it can also be provided that the head of the pin rigidly attached to the clamping sleeve is elongated in front view and has a cylindrical surface for bearing on the U-bottom of the connecting member. This measure ensures to an increased extent that under tensile load the clamping sleeve does not rotate relative to its connecting member, but remains connected to it in a rotationally fixed manner, as is necessary for proper clamping by means of the clamping bolt _e

An embodiment of the turnbuckle according to the invention is shown in the drawing, in which:

1 shows a turnbuckle in side view;

FIG. 2 shows a section along the line II-II in FIG. 1;

3 shows a section along the line III-III in FIG. ₀ 1; and

Fig '4 is a sketch of the present Yeranschauliehung than at a Want & nspanner used turnbuckle particular problems _β

Figo 1 shows two threaded clamping sleeves 1 and 2, which have a hexagonal outer profile _o The clamping sleeve 1 carries a forked head 2, which is tightly and practically rigidly connected to the clamping sleeve Λ via a threaded extension 3. A head pin 4 can be inserted through the two legs of the fork head 2, which is designed as usual, which is looped around by a rope end (not shown) and secured against falling out by a spring ring 5 or the like, _{or the like}

The adapter sleeves. Λ and 2 are screwed with their ends facing each other, a clamping bolt 6, which is on a

Half with real thread and on the other half with Left-hand thread stranding isto In the thickened, in cross-section also hexagonal or square longitudinal center of the bolt 6 is. a double lever with a TJ-shaped cross-section 7 stored, which when unfolded forms an actuating lever for rotating the clamping bolt 6 and which when folded in, the two Holds clamping sleeves 1 and 2 positively and secured against twisting -

In the outer end of the clamping sleeve 2 is also Tightly and practically rigidly seated, a pin 8 is screwed in, which has a spherical head 9. The pin 8 penetrates a hole 10 having a considerable amount of play of a connecting member 11 bent into a U-shape from a sheet metal strip, a head pin 12 can also be inserted through the legs. As can be seen from FIG. 4, the connecting piece 11 - when using the turnbuckle as a turnbuckle - connected to a stirrup-like putting 13, after which the pin 12 secured against falling out by an open spring ring 16 wirdo In Figo 4-, the arrow A indicates the direction of the Turnbuckle indicated according to a first sail mast position. When the mast is swiveled to a new position in which the ropes (shrouds) holding it at the side in the direction according to the arrow B, the turnbuckle should slide accordingly on the putting 13 and in the new direction B. swiveled-in is, however, as with the usual turnbuckles,

509028/0321

the outer end of the turnbuckle assigned to the putting 13 is designed like the _{connection end shown on the left in Fig. 0} 1, so the turnbuckle, which is still under tension, is often not automatically shifted into the new position due to tilting on the other hand, a universal joint in front, namely the joint between the pin 12 and the putting 13 and the joint between the head and the connecting member 11. The turnbuckle is consequently more flexible and can - even under high tensile stress - more easily in its position change the putting 13 in the required manner.

Instead of a spherical head 9 and an elongated end view of head 14 · may be provided at the joint pin 8, as is indicated by dashed lines in Fig .. 3 _o The U-base facing contact surface 15, this elongated head 14 is advantageously formed cylindrically mnd of curvature The TJ-bend adapted This ensures to a particularly high degree that the clamping sleeve 2 is coupled to the connecting member 11 in a torsion-proof manner with only slight tensile stress, so that the lock can be tensioned in the usual way by means of the double lever 7 «
