    Connecting link - installation without tools
    The invention relates to a connection lock for tire chains with an elongated receiving opening for receiving two chain links, wherein the receiving opening is surrounded by a first continuous longitudinal ridge, a second longitudinal ridge, interrupted by an insertion opening and two transverse webs, and the chain links in the Receiving opening by means of a locking bolt, which can be used with one end in a bore of the first longitudinal web and is directed with its second, free end to the insertion of the second longitudinal web, are secured against sliding out.
    A connection lock of this kind is disclosed, for example, in DE 16 05 670 B2. In this known connection lock the locking pin is a spiral tension pin which is inserted into the hole formed as a through bore of the first longitudinal web to secure the chain links. However, the force required for the insertion of the dowel pin is large, it is this a hammer needed and there is a significant risk of injury from chipping the Spiralspannstiftes when it is driven into the hole. The disassembly of the turnbuckle by removing the spiral tension pin is problematic because either the pin with the help of a hammer and a punch must be removed. In practice, however, the spiral tension pin is often so corroded that the connection lock for releasing the chain links must be cut with a cutting torch.
    Another link of the subject type has become known from DE 765 176 B. In this link, the locking pin is slidably mounted in the bore of the first longitudinal ridge and it carries on its outer, the tread of a vehicle tire facing the end of a widening in the form of a head, which rests in use on the tread, so that the bolt is held in a locking division and the chain links are secured against sliding out of the connection lock. A disadvantage of this solution is the fact that with loose chain a concern of the head of the locking bolt on the tread is not guaranteed, so that the bolt slip and can unintentionally release the chain links.
    It is an object of the invention to provide a connection lock which does not show these disadvantages.
    This object is achieved, starting from a connecting lock of the type mentioned in that according to the invention, the bore is formed in the first longitudinal ridge as a blind hole, in the first longitudinal ridge of a side surface starting a threaded bore leads to the blind hole, a spring pressure element in the threaded hole is screwed, the spring-loaded locking part is directed into the blind hole and is locked in inserted into the blind hole closure pin in a recess on the circumference
    The invention provides a connection lock, which has several advantages: The lock is to be mounted by hand without tools, with a risk of injury is avoided by absprittemde parts. The dismantling after a winter season or for shortening the chain can be done simply by lifting the locking bolt with a screwdriver. Compared to a spiral pin, which occasionally shears off in practical use, the resistance to breakage of the massive locking pin is greater. Since there is a blind hole, which is closed on the tread side, no dirt can penetrate from there.
    In an expedient variant, the recess in the closure bolt may be formed as a circumferential groove to simplify the assembly.
    In this sense, it is also advantageous if the locking part is designed as a ball.
    In order to be able to keep the diameter of the blind bore limited with good securing of the chain links and to remove the locking bolt by means of e.g. a screwdriver, it is recommended that the closure pin in the tapped portion has a diameter which is smaller than the diameter of the portion which is in the receiving opening in the assembled lock.
    The invention together with further advantages is explained in more detail below with reference to an exemplary embodiment, which is illustrated in the drawing. In this document, we will show you the following: P125S8 • · · · · * ·· **
    1 is a perspective view of a connecting lock according to the invention prior to assembly of the locking bolt,
    1 with hinged chain links and assembled locking pin, likewise in perspective view,
    Fig. 3 is a side view of a connecting lock according to the invention with mounted locking pin and spring pressure piece
    4 shows a section along the line IV-TV of Fig. 3rd
    As can be seen from FIGS. 1 to 4, a connecting lock 1 according to the invention has an elongated receiving opening 2 for receiving two chain links K1, K2, which may be part of a running net of a tire chain, in particular a snow chain or tire protection chain. The receiving opening 2 formed in the connecting lock is surrounded by a first continuous longitudinal web 3, by a second longitudinal web 5 interrupted by an insertion opening 4 and by two transverse webs 6, 7. When mounted lock 1, the chain links kl, k2 are secured in the receiving opening 2 by means of a locking bolt 8 against slipping out. This closure pin 8 is substantially circular cylindrical and can be used with one end in a bore 9 of the first longitudinal web 3. He is then directed with its second, free end to the insertion opening 4 of the second longitudinal web 3. As shown in Fig. 4, the bore 9 is formed as a blind hole, i. open to the opening 2, to an outer surface 10 which is directed towards the roadway, but closed.
    To secure the locking bolt 8 against falling out of the bore 9 in the first longitudinal web 3, starting from a side surface 11 (see FIG. 4), a threaded bore 12 to the blind hole 9, wherein in this threaded bore 12, a spring pressure piece 13 is screwed. The spring-loaded latching part 14 of the spring pressure piece 13, designed here as a ball, is directed into the blind hole and locked with inserted closure pin 8 in a recess 15 at its periphery (see Figure 4). Advantageously, the recess 15 is formed as in the embodiment shown as a circumferential groove.

    Spring plungers are available in many dimensions, e.g. with threads M3 to M20 commercially available, wherein the locking part is formed either as a ball or as a bolt, see, e.g. www .bossard.com. For an assembly of the lock 1, starting from the situation according to FIG. 1, provided that the spring pressure piece 13 is already screwed into the threaded hole, the closure pin 8 is pressed into the bore 9, wherein first the locking part 14 of the spring pressure piece 13 is forced outwards, which is facilitated by the chamfered end of the bolt 8. Upon further pushing in of the bolt 8 in the bore 9, the recess 15 enters the region of the spring pressure piece 13 and the locking member 14 engages in this recess 15, so that the bolt 8 is now secured against falling out. If before the described assembly, the two chain links kl, k2 were introduced in the manner shown in Fig. 2 in the opening 2, these chain links mm are secured against sliding out through the locking pin 8, since it is so dimensioned that the entry port 4 at least blocked is that the chain links kl, k2 can not slide between the remaining gap between the free end of the bolt 8 and the two ends of the second longitudinal web 5, between which the insertion opening 4 is located.
    As is apparent from Figs. 1 and 4, has the locking pin 8 in that portion, with which it is pushed into the blind hole 12, a diameter dl, but in the portion which is in the assembled lock 1 in the receiving opening 2, a something larger diameter d2. On the other hand, since the inner surface 16 of the first longitudinal ridge 3 is curved inwardly toward the opening 2, it is possible to form a simple tool on the protruding edge 17 (see FIG. 1) of the larger diameter portion 8 of the bolt 8 for removal of the bolt 8. eg to put a screwdriver, and to bring the bolt out of engagement with the locking part 14 of the spring pressure piece 13, wherein this locking part is pushed back against the force of the spring pressure piece 13 built-in, but not visible spring.
    As can be seen from the figures, the first longitudinal web 3, in which the bore 9 is formed, formed stronger than the transverse webs 6,7 and the second longitudinal web 5. More specifically, it is in a direction parallel to the axis of the bolt 8 and parallel to the transverse webs 6,7 approximately twice as thick as the second longitudinal web 5, with the already mentioned curvature in the blind hole 9. The first longitudinal web 3 is also in one
    Direction parallel to the axis of the threaded bore 12 thicker than the second longitudinal ridge 5, wherein the largest thickness in the region of the threaded bore 12 and the blind hole 9 is present.
    The connecting lock is made of case-hardening steel, for example, and its locking bolt 8 of tempered steel. For the spring pressure piece 13, in view of the purpose of use, e.g. In a snow chain, a stainless version is used.
