The innovation relates to a web- or ₀ plattenformig.es Yerbin & ungs "and Sehlußglied for _{Reifensqhutsteetten?} in particular those whose running part consists of web or plate-shaped running links which are held in the chain _{by connecting links f} like rings _{r 0} ■ '■ -.

In this context, tire protection chains are to be understood as those that are used in "rough" operations ^ especially with gravel-like subsoil * such as quarries ^ underground " _- on construction sites or in companies with similar conditions in Yerwendi

can be found, on the one hand to protect the tires from damage and also to increase the grip of the drive wheels and to prevent slippage, as well as anti-skid (snow chains) _and chains of the first-mentioned ■ 5 type are a densely closed tanks be ~

Sitting, - the interstices j "" e according to the requirements should also be adjustable, - must have a good self-cleaning, d _o h _o of the tanks must be so .Flexible "his / that it can follow the flexing movements of the tire _s without this to bell 0 aehädigen _o · /

Chains of the second type, d _o ho Skid * are generally prepared from individual Spurkreuzenj diamonds or other items composed ₀ existence of these parts or _a part of one or more armor run of the chain "vorausse'tzungs ~ -_ according of web- or plate-shaped * running members with annular links ,, so the TeUe ₁ are made from a particularly hard and tough materials ■, "hardened after" assembly but this has become impossible at break a substitution of single limbs, d "h _s, the corresponding part of the chain had to will be replaced ! »'- which was often not possible on the spot. In the case of chains with "... Closed armor" there is a further difficulty due to the fact that the closing links generally known up to now for * "cLieaen" purpose represent a foreign body * - which impaired the running properties of the chain:

It has therefore already been proposed to design a bar _{-shaped or} plate-shaped body as a double hook with two slots which lead via introduction channels to a common central introduction opening, with a guide nose opposite the introduction opening which only allows rings to be inserted and removed in a certain upright position of the parts concerned enables _o

The present hiring, on the other hand, concerns a connection. and final link that is particularly easy to manufacture and offers even greater security and can be used to connect chain parts of any type _{or similar}

Accordingly, is the basic idea of hiring? that the connecting and final link has a slot parallel to the running edge with a central insertion opening for the connecting links facing the tire. as well as a locking body for closing the insertion opening _ö

It may further zweckmässig.sein _g if the slot is arranged eccentrically in a known manner with respect to the height of the web-like or "plate-shaped member in such a manner _g that the distance to the insertion ungs opening comprising edge (the bottom) lower than the one for the closed upper "

: side (Laofkante) ₀ ■

Another essential spatial concept of the masonry is ^ that a bolt ^ for example a visual bolt ^ is provided to close the insertion opening, the shaft diameter of which exceeds the width of the slot and the width of the insertion opening without this need su provided for receiving fasteners with a threaded bore _$ but this would be attached such a threaded hole before hardening after hardening self verbieteto If j it leads to a weakening of the circuit element and other Unzuträgliehkeiten ^ because the thread in. Hardening can warp _o

Can the execution be made like this _? that the shank of the bolt has such a strength _t that - possibly. with deformation of the thread - can be held between the inner edges of the insertion opening and the opposite slot surface pressing. » it also being possible to _see that the bolt is designed to be resilient or "springy comprises means such that _s der.'Preßsitz istο ensured between the inner edges of the Einfuhrungsöffnung and the opposite slit surface

Another." The preferred embodiment consists of that the shaft diameter of the bolt is selected in such a way that he between the inner edges of the, inlet opening and

the opposite Schiitafläche Mt game is out ^ - and that dia bolt anyway a nut screwed against loss secured _0. Here, the bolt may or * the mother be equipped with limited thread _s such that the bolts in both limits iängsVersehieblich "and 'is freely rotatably supported between the inner edges of the insertion opening and the opposite slit surface _o Xn this to = connexion it is ireiterhin advantageous if the thread limiting the mother for a disseminated in the or ₀ a mixture of the parent ring "B ₀ is made of plastic" , the plastic ring can also simultaneously serve as a nut retainer _o

An embodiment of the subject of the control is on Hand of the accompanying drawing explained in more detail in the

Opening 5 for this _o This introduction opening is closed by a bolt 2 after the rings have been hooked in, which in the illustrated embodiment is secured by a nut with a thread limitation. The inner edges of the introduction opening 5 are shown broken

As is apparent from Abbo 2 is.t _s besitst the bolt a Schaftdurohmessex% of both the width of -Schlitzes 4 and that of the Einführungsoffhung exceeds 5 _s but which is selected _to? that a certain amount of play remains · The length of the bolt is selected so that there is considerable play in the longitudinal direction even when the nut 3 is screwed on. In this manner, the bolt head icann or _o when the nut to meet obstacles, stones -As öd _{or the} like _D is _t easily rotate and move laterally ^ without the screw itself dissolved wirdo

On the other hand ist.es also possible to choose the bolt shaft so strong _'9 that he ά.βτ between the upper surface of the slot and the edges of Einführuaigsöffnung- 5 pressingly -contents / is "wherein the Bolsen under circumstances under Yerformung of ■ 20 thread-inserted 'wirdo -Andererseits but it is aucii · - möglichg the shaft 2 itself' resiliently form ^ Doh _e longitudinal "slots ,, to thereby form the press fit herbeiz" to U £ ühren _e.

so that it is held elastically between the upper slot surface and the inner edges of the insertion opening «, the bolt is expediently passed so far that between the
