Bracing chain for lashing objects, especially on vehicles

The invention relates to a tensioning chain for lashing sensitive objects on vehicles several links lined up next to one another.

The invention is based on the object of designing a tensioning chain of this type in such a way that at simple structure an adaptation to the respective load condition ensures 1st and shocks of be kept away from the lashed objects.

In a tensioning chain of the type described at the outset according to the invention, this is achieved by that at least one member is designed as an elastic length damping member.

To facilitate the assembly of the tensioning chain, the length damping link is at one end of the chain, Preferred puppy between an end-side Schliefiglled of the chain, for example a hook and a Lttngensenspiegel provided so that the Längendämpfglled is always in an accessible area is located.

So that the length attenuator can be replaced if necessary or on other tensioning chains <can be attached, it is, in particular, with

a shackle or the like., releasable to the neighboring

r chain links attached.

j. In a particularly advantageous embodiment

is that quei rigid to the chain bending direction

(Articulated length attenuator with connecting pieces

; attached to the adjacent chain links, so

■ that the flexibility of the bracing chain is not

is affected and the length attenuator is not exposed to bending stresses.

To achieve a high level of unresponsiveness

and wear and tear on the length attenuator, preferably cylindrical housing in which a damping spring, in particular one lying in the housing axis Helical compression spring is arranged, whereby also a very compact structure of the length damping element results.

For secure storage, the damping spring is one end on an end cover of the housing and the other End supported on a support disc displaceable in the longitudinal direction of the housing, which is preferably on a is attached through the end cover guided rod from the housing.

To the long attenuator, for example for the purpose the cleaning, to be able to open easily, is a front cover of the housing, in particular the one for the support the damping spring -provided end cover, for example with an external thread, releasably attached, whereby it is also possible to replace the damping spring and thus by choosing different damping springs the length attenuator to the respective requirements

According to a further feature of the invention, the connecting pieces of the length damping member are against each other

rotating, preferably d's Abstutκ "disc provided on the circumferential axial grooves Iu of the inside of the housing provided for axial webs en engages, which in particular are exclusively provided on a thin-walled end portion of the housing so that a simple structure, a twisting of the tensioning chain is prevented.

In a further embodiment of the invention, the length expansion of the length damping member is positively limited by a stop, a stop sleeve preferably being arranged around the rod in the housing, the free one of which is End face provided as a stop face for the opposite end face of the support disc 1st, so that the compression spring cannot be compressed up to block height and the damping effect is retained.

The invention is explained in more detail below with further details; the drawings enter AusfUhrungsbelspiel with the essential parts for the invention approximately to scale again. These parts are, if they cannot be taken directly from the drawings, based on the Drawings explained.

FIG. 2 shows the length damping link of the tensioning chain according to FIG. 1 in an axial section and enlarged; FIG. . ^;

Fig. 3 is a section along the line III - III in Fig. 2.

As shown in FIGS. 1 a to 1 c, a tensioning chain 1 according to the invention has a chain strand 2 of any length made of oval ring links 3, with ^{a hook 6 being attached to one end of the chain strand 2 via a closure link 2} J and an enlarged oval link 5. At the other end of the chain strand 2, a longitudinal tensioning link 8 is attached via an enlarged oval link 7, which has a rotatable tensioning spindle 9 and connecting pieces 10, 11 which can be rotated with respect to the tensioning spindle 9 at both ends. On the connecting piece 11 of the longitudinal tensioning member 8 facing away from the chain strand 2, a length damping member 12 with a complementary connecting piece IJt is articulated about an axis at right angles to the longitudinal direction of the chain

Axis is formed by a detachable threaded bolt 14. A hook 16 with a shackle 17 is attached to the connector 15 provided at the other end of the longitudinal damper 12, the shackle 17 being pivotably mounted on the connector 15 about the axis of its bolt 18 which is perpendicular to the longitudinal direction of the chain. The tensioning spindle 9 of the longitudinal tensioning member 8 is releasably attached to the oval 7 by a correspondingly guided one end on the connecting piece 13 and the other end with a snap hook secured strengthened chains 19 against Verdrehe'- and thus against ¹ accidental adjustment. -] · ■

The length damping element 12 "has a cylindrical housing 20, which at one end is supported by an in the j Inner diameter enlarged end section 21 i is formed. In the free end of the end section 21 there is an annular disk-shaped end cover 22 inseparably, for example by welding, used, the laser-shaped, with a bore ι 23 for receiving the bolt 14 provided connector 13 carries. At the opposite end the housing 20 has an internal thread 24 into which a corresponding external thread annular disc-shaped end cover 25 is screwed in, the key bores on its outer end face 26 and the opposite to the housing 20 through

a threaded pin 27 engaging in the thread is secured against rotation. In the end section 21 of the Housing 20, an annular disk-shaped AbsUtxseheibe 28 is mounted displaceably and secured against rotation, with two diametrically opposite one another on the inner surface of the housing section 21 Axial webs 29 are provided, in which the support disk 28 with axial grooves 30 provided on the circumference intervenes. A cylindrical rod 31 is fastened to the support bracket 28 and passes through the bore 32 of the end cover 25 is guided out of the housing 2O and at its end the connecting piece 15 corresponding to the connecting piece 13 is formed by the The training described against the connection piece 13 is secured against rotation. A stop sleeve 33 is located on the inner end face of the end cover 25 attached, which surrounds the rod 31 and protrudes into the band section 21 by a small amount. The free end face 34 of the abutment sleeve 33 forms a stop face for the opposite end face 35 of the Support disk 28, so that this and thus the connecting piece 15 only by a certain amount in the axial direction can be moved relative to the housing 20. Qm the stop sleeve 33 or the rod 31 is inside of the housing 20 is arranged a damping spring 36 geULdete by a helical compression spring, which moves with its an end to the

inner face of the end cover 25 and with its other end on the inner face of the Support disk 28 is supported. The tension difference can be reduced by the length damping member 20 Extend and shorten the load elastically.

As FIG. 2 also shows, in the jacket of the housing 20 are adjacent to the end cover 25 and adjacent to the housing data section 21 through-holes 37 is provided so that water or the like possibly penetrated into the housing 20. by itself again you can remove your housing from £.
