Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tire chain, in particular to a tire slip prevention chain, according to the preamble of claim 1.

In this type of tire chain, the inner part is formed to be expandable so that the tire chain can be placed over the tire from the outside during installation. The clamping section is fixed to one end of the inner section and is slidably guided through a turning section provided at the other end of the inner section.

As a result, the clamping part can slide appropriately through the deflection part when expanding the inner part. However, a major drawback of this type of tire chain is that it cannot be wrapped while the vehicle is stationary, but can be installed while the vehicle is in motion. When the tire chain is placed over the tire, the free end of the tightening section is located on the outer surface of the tire and in front of the tire tread. Therefore,
It is not possible to close the inner part by tightening the cord. In order to close the inner part, the car must first be moved until it is positioned next to the. If the car is stuck in the snow and can no longer move, it is simply impossible to install tire chains of this type in driving position. On the other hand, even if the car can run, it is difficult to install this type of tire chain. Since the tire chain is initially only loosely attached to the tire yard, there is a risk that the tire chain will fall off the tire when the vehicle is subsequently driven with the vehicle. Moreover,
It has been demonstrated in practice that in some cases the tire chain can be thrown off the tire. In such cases, the wheel cover or brake pipe may be damaged.

Since the inner part of this type of tire chain cannot be opened, the tightening part remains on the outer side of the tire.

Furthermore, this type of tire chain is difficult to install, especially for inexperienced drivers. The inner part consists of a curved body with a cushioning attachment, and when the tire chain is removed, the attachment resists the spring force of the curved body.
It has to be bent far apart. In this case, the curved body must be grasped by twisting the hands and mounted on the tire.

Such gripping is cumbersome and even more so since the chain must then be bent further outwards against the spring force of the inner part. Moreover, in this case the chain comes into contact with the body and therefore the clothes are often soiled.

The turning part for the clamping part is provided at one end of the inner part, so that the clamping part is located in the running part, so that the fragment of the clamping part forms the anti-slip member of the running part. It is installed on the inside part of the tire chain. In the known tire chain, the clamping section is formed by a clamping chain, which is made up of very short sections, so that the clamping chain is
It can be easily pulled through the turning section. Thereby, the fragments of the clamping section located in the running section are already utilized even after a short period of use of the tire chain until it can no longer perform its anti-slip function.

In some cases, the tightening can cause the piece to break in the running part, with the result that the tire chain is no longer held by the tire and falls off the tire. Finally, the disadvantage of turning the part at one end of the inner part is that the clamping means that the running parts adjacent to the part are located at a very large distance from each other, with the result that the running part This area has a very large gap width. Tightening therefore results in particularly high wear of the running part adjacent to the part.

An object of the present invention is to arrange the tightening part on the tire chain as follows while taking into account the reduction of wear. That is, it is possible to complete the installation of the tire chain while the vehicle is stopped. It is important to arrange the location so that it can be done.

According to the invention, the object described above is solved by the features of claim 1.

With the tire chain according to the invention, the inner part can be opened, so that the attachment sometimes goes behind the tire and can be closed on the outer side of the tire or on the side of the tire.

Next, the tire chain should be positioned so that the lock part is behind the tire.
T? Until this occurs, the wear of the running parts located on both sides of the inner locking part which is moved back to the rear of the tire does not increase, so that the running parts are worn out evenly.

Other features of the invention will become apparent from the other claims, the detailed description, and the drawings.

The invention will now be described in more detail with reference to some embodiments illustrated in the accompanying drawings, in which: FIG.

The tire chain illustrated in FIGS. 1 and 2 has an inner part 1 which is connected to an outer part 6 via a running part 2. The tire chain shown in FIGS. The inner part 1 has an annular mounting curve 4 with a hook 5 at one end and a fastening part 6 for a fastening part 7 at the other end. For mounting, on the curved body 4 a pivot element 8 for the running section 9 is provided. Attachment is such that the curved body 4 is formed by a spring bow, on which the pivot members 8 are provided and which are covered by cover pieces 10 in the region between the pivot members. The cover piece 10 is preferably made of synthetic material. As shown in Fig. 1, the inner part 1 is formed of a curved body 4 for attachment when a tire chain is attached, and a part of a part 7 for the attachment to complement the curved body and create a closed ring. Ru. Mounting: The curved body 4 extends over an angular range, in particular over 600°, is spring-elastically formed and can be expanded for mounting on a tire. In addition, the curved body is installed,
It is also possible to make it shorter, for example extending slightly over 180°. In this case, the remaining part of the inner part can be formed by the chain 1 member. On the other hand, it is also possible to use chains, ropes, etc. for attachment instead of the curved body. However, the mounting curve has the advantage that it greatly facilitates the mounting of tire chains.

In the illustrated embodiment, the clamping part 7 is formed by a clamping chain. The clamping chain is fixed by its end member to the fixed part B, and the attachment is carried out by means of two guide parts 11, 1 fixed to the curved body 4 and located at a distance from each other.
2 and is guided by 1, IQ and diverted to the outer part 3 by a diverting section 13. It is also possible to use a rope or the like for tightening instead of a chain.

The running portion 2 consists of longitudinally interlocking longitudinal chains. −
It is also possible for the force running part to consist of other chain-ring elements, such as interlocking bars or ring elements. The running segment 9 extends obliquely from the pivot member 8 with respect to the circumferential direction of the tire.

Adjacent running sections 9 are connected to each other by track sections 14 extending in the circumferential direction of the tire.

The pivot elements 8 are each provided in pairs, the six pairs of pivot elements being located at a short distance from each other. As an alternative to such an arrangement, it is also possible to provide a running section extending perpendicularly to the circumferential direction of the tire from the inner part to the outer part, so that such a tire chain has the shape of a ladder chain. . It is also possible for the two running parts 9 to be fastened to a single pivot member. Furthermore, the running parts can be constructed in any suitable manner.

The outer part 6 is formed by a steel cable 15.

The steel cable consists of vertically elongated chain rings that engage with each other, and has annular members 16, 17, etc. at each end thereof. steel cable 1
5, it is also possible to provide a curved body, a lobe cable, etc. for attachment.

The pivot element for the running part 9 is formed in the outer part 6 by hooks 18 or chains which are likewise provided in pairs, the six pairs of hooks being each separated from one another by a chain 19. .

It is also possible to provide several chain rings 19 between the six pairs of hooks 18. It is also possible to connect the two running parts J1'9 to a single hook 18. The running section 9 extends from the hook obliquely to the circumferential direction of the tire to the track section 14 .

In order to deflect the part 7 in the outer part 3, the clamp is designed in the exemplary embodiment as an annular member 20, and the clamp is provided with a deflection part 20 guiding the part.

The annular element 20 forms a connecting element with which the two hooks 18 to which the running section 9 is connected can also be connected to one another. With such an arrangement, the clamping section 7 is guided to the outer section 3 in the region of the pivot point of the running section piece, so that the clamping section extending over the running surface of the tire is guided to the section 2 of the section 7.
1 is located between the two running sections 9. The tightening is such that the part 7 can slide through the guide part 11.12 and the deflection part 16.
It is formed from a chain ring that is much smaller than the chain ring of.

Thereby, the clamping section 21 projects at the height of the running section 9, so that the running track contact of the clamping section is considerably less than that of the adjacent running section 9. Therefore, the tightening piece has a low degree of wear and has almost no anti-slip function. Rather, it is the running section 9 that performs the sliding function. The tightening therefore ensures that the armor 7 does not break and that the tire chain is always held on the tire.

A connecting member 22, which is advantageously designed as an annular member, is movably arranged in the clamping part 7. On the other hand, it is also possible to arrange a sliding cover or other connecting parts such that the clamping part 7 can be connected with the hook 5.

When attaching the tire chain to the tire, first the coupling member 22 is removed from the hook 5, so that the inner part 1
is completely opened. The clamping is then extended until the part 7 is pulled out of the deflection part 13 and the guide part 11.12 until the distance between the connecting part 22 and the fixed part A is increased. The tire chain is placed on the ground or held in the hand in front of the tire with the hook 5 and the fixing part 6 facing towards the tire. The clamping part 7 is pulled towards the inner part by its entire length. The attachment of the inner part 1 is then carried around to the rear of the tire, in particular by means of hooks 5, until the curved body 4 reappears on the other side of the tire. - The blade mounting can also extend the curved body 4 to the rear of the tire by means of the fixed part B until it is located in the lateral area of the tire on the other side of the tire. In this case, the chain 7 is also tightened behind the tire.

In both cases, the connecting member 22, which remains loosely located on the chain 7, is then hooked onto the hook 5, thereby closing the inner part 1. The tire chain is then moved back again until the locking part 22.5 is located behind the tire. In order to confirm this condition, force diagonally opposite to the lock part /<-piece 10' (Fig. 1)
are visually marked, for example kept in a different shade than other cover pieces.

The cover piece 10' is located precisely in front of the tire if the locking parts 5, 22 are in the correct position behind the tire. After the tire chain has been moved back, the mounting, which is located partially in front of the tire, is gripped by the curved body and bent elastically, at the same time being mounted on the tire from the outside. When attaching the curved body, the chain 7 is automatically tightened because it is slidably guided through the coupling member 22. As a result, the coupling element is always guided in the required position on the spool. Since the chain ring is short, the chain can be pulled through the connecting member without getting caught. The coupling member 22 connects the fixed part 6 and the guide part 1.
In the region between 1 and 1, the clamp is arranged movably on the steel, so that the connecting member can always slide up to the guide part 11. Thereby, it is ensured that after the mounting has been completed around the curve, the coupling element is always close to the grip at the rear of the tire, so that it can be easily hooked onto the hook 5. Furthermore, when tightening, the chain 7 slides easily through the guide members 11, 12, the turning section 13, and the annular member 20 of the outer part B, and as a result, the tire chain can be easily expanded and installed on the tire. become.

The diverting part 15 is located at a distance from the fixed part 6 and the guiding part 12 (FIG. 1), so that the tightening of the chain 7 is not in the area of the tread 23 of the tire, but rather through the running surface of the outer part 5. You will be guided to. Thereby, it is possible to tighten the tire chain immediately after mounting it on the tire without moving the vehicle.

After installing the tire chain on the tire, attach it to the
The fr body 4 is returned to its original state after relaxation. Tighten with chain 7
is tightened from the outside of the tire, the mounting is done on the curved body 4.
The ends 5, 6 of are pulled in opposite directions. This is because the chain 7 is tightened from the fixed part 6, the connecting member 22 hung on the hook 5, the guide parts 11, 12, the turning part 16,
This is because it is guided through the chain ring 2o. The clamping chain is then tensioned by the beam 17 and there turned about 180° into the annular member 16. Furthermore, the chain is tightened,
It is also pulled by the annular member 16, turned once more through 180° and then threaded or wound into the steel cable 15 of the outer part 6. When the inner part 1 and the outer part 6 are sufficiently tightened, the hook 24 provided at the free end of the chain 7 is hooked onto one of the chain rings of the steel cable 15.

The annular member 16,17 forms a turning member for the chain 7, so that the clamp can be tightened by tightening the chain.
Not only the inner part 1 but also the outer part 3 and therefore also the running part 2 are tightened. The advantage of using an annular member or the like as a deflection member is that the chain does not get caught during tightening, so that the tire chain can be tightened more easily. Since the rings of the fastening chain are short, even if the fastening chain is strongly fastened, the fastening chain can be easily pulled by the annular member 16, 17. Chains are easily tightened if they are not tightened enough. In that case, the hook 24 is used to tighten the chain 7.
can be reliably hooked onto the outer part 3, so that there is no risk of the hook becoming accidentally dislodged during driving.

The deflection elements for the tightening chain 7 are located entirely on the inner and outer parts of the tire chain, so that the deflection elements do not come into contact with the road surface, as is the case with known tire chains. The running part 2 is thereby free of deflection elements and consists only of the chains necessary for tightening, so that the running part can be optimally adapted to the intended use. The turning members 22, 13, 20, 16.17 are
Less wear and therefore longer life.

Advantageously, the hook 24 is connected to a prestressing element 25 . The prestressing element 25 is in the exemplary embodiment formed as a rubber ring, in which the hook 24 and the clamp are fastened to one of the chain rings of the chain 7 . The prestressing element 25 is arranged in the chain 7 so that the prestressing element can be extended until the chain ring captured by the prestressing element assumes its extended state. If the tightness of the tire chain is reduced during driving, the reduced tightness can be compensated for via the prestressing element 25. Instead of the rubber ring, it is also possible to install other prestressing elements, such as those that allow automatic tightening of the tire chain during use.

Since the coupling element 22 is supported slidingly on the clamping chain 7, tire tolerances can be compensated for very easily. It is therefore also possible to use a tire chain with a constant circumference for tires of various sizes. In the tire tolerance range, the distance between the ends 5 and 6 of the curved body 4 differs depending on the size of the tire. The tightening section 7 compensates for this spacing and closes the inner section 1 annularly.

The inner part 1 illustrated in FIGS. 1 and 2 is assembled from individual elements on a unitary basis. hook 5,
The fixing part 6, the guide parts 11, 12 and the deflection part 16 are formed by separate components which are connected to a piece of spring wire (FIGS. 3 to 11). The pivot element 8 for the running part 9 is also mounted on the spring bar of the curved body or is pushed into the spring bar. The spring bar, at least in the area of the pivot member 8 and the guide part 11.12, is provided with a torsion arrester which prevents twisting of the pivot member and the guide part, so that the running part cannot twist relative to the inner part. do not have. This greatly facilitates the installation of tire chains. The torsion arrester is mounted by a suitable design of the cross-section of the spring bar of the curved body 4, and can be formed, for example, in a triangular, square or polygonal or non-circular cross-section. If the cross section of the spring bar is circular, the spring bar is connected to the pivot member 8 and the guide part 1.
1.12 can be deformed in the area of 1.12, or the separate components can be shifted, which ensures the prevention of twisting of the articulated running parts.

Both guide parts 11.12 are of identical design, so that only guide part 11 will be described below. The guide part 11 has a constant thickness over its height and is provided with a fixing piece 26 which is, for example, approximately rectangular when viewed from the front.

The fastening piece 26 has in the center a rectangular opening 27 adapted to the cross-section of the spring bale. The lower side 2 of the fastening piece 26 is bent convexly towards the outside and transitions into mutually parallel sides 29.50 of the fastening piece. The side surface 29.50 is curved in the form of an arc and parallel to the side surface 31.3 of the guide piece 36, which is rectangular when viewed from the front.
Move to 2. The guide piece 33 has an approximately circular through hole 34 for the fastening chain 7 in the center. The width of the guide piece 33 is wider than the width of the fixed piece 26. Edge 3 forming through hole 34
5 is bent concavely around the entire circumference with respect to the axis A of the through hole 64, and then bent into an arc shape and transferred to the end surfaces 36, 67 of the guide piece 33. Therefore, during tightening, there is no possibility that the chain 7 gets caught in the guide piece 36, especially at the transition from the edge 65 to the end faces 36, 57.

The edge 38 forming the opening 27 is rounded at the transition to the end faces 36, 37 (FIG. 4), so that no ridge is formed in this area. Thereby, the mounting is facilitated by the mounting of the guide part on the curved spring bar.

As shown in FIG. 6, the guide portion 11 is formed symmetrically with respect to the longitudinal center plane B. As shown in FIG. The longer side of the rectangular opening 27 lies parallel to this longitudinal central plane, while the narrower side lies parallel to the flatness of the guide piece 5 which is bent in an arc and transitions into the side surface 51.52. is located parallel to the upper surface 69. Installation is done on the fixed part 11.12 on the spring bar of the curved body.
The state locking is obtained by the cover piece 10 as well as by the fixing part 6 with a stop for the guide part 11, which will be explained in further detail. As shown in FIG. 1, the guide piece 33 is oriented in the direction of the axis of the tire, so that the tightening of the chain 7 is carried out on the side of the curved body 4 that is oriented in the direction of the axis of the tire. It is guided along a segment of the curved body. The diameter of the through-hole 64 is larger than the maximum width of the chain ring of the chain 7, so that the chain ring is in the guiding part 11.12.
It will not get caught in the through hole.

As shown in FIGS. 5 to 7, the fastening part B is provided with an ear 40 with a particularly circular fastening hole 41 for the terminal chain ring of the fastening chain 7. As shown in FIGS.

The ears 40 have a substantially rectangular cross section (Fig. 7),
Its end face 42 is bent partially circularly around the axis 43 of the fixing hole 41 and transitions into the outer edges 44,45 of the ears parallel to each other. The edge 46 of the fastening hole 41 is extremely bent with respect to the axis 43 (FIGS. 6 and 7). The edge 46 adapts to the shape of the chain to be hung in the fastening hole, so that the chain can be joined to the edge 46 in a plane.

The ears 4G connect to seven circular flange 47.

7. The diameter of the flange 47 is at least twice as large as the width of the ear (FIG. 7). On the other hand, an elongated holding part 48 is connected to the 7 flange 47, the cross section of which is adapted to the cross section of the spring.

Corresponding to the opening 27 of the guide part 11.12, the holding part 48 also has a rectangular cross section. The holding part 48 is provided with grooves 51, 52 on its longer side. In order to connect the fastening part 6 to the spring bale, a plug-in cover (not shown) is provided which is pressed onto the retaining part 48 and the associated spring bale end. The grooves 51, 52 ensure a completely secure attachment of the plug-in cover to the holding part 48. The length of the plug-in cover corresponds at least to the distance between the grooves 51, 52 and the free end of the holding part 4.

As shown in FIG. 1, a connecting member 8 is joined to the flange 47, and a guide portion 11 contacts the connecting member 8 on the side of the connecting member. Both guide parts II, 12 are separated from each other by a cover piece lO.

The hook 5 (FIGS. 8 and 9) likewise has an elongated holding part 53, the cross-section of which is adapted to the cross-section of the spring bar. The retaining section is likewise located on its longer side 54;
55 is provided with grooves 56 and 57.

The hook 5 is connected to the associated spring bar end by means of a retaining part and a bayonet cover which is likewise pressed onto the spring bar end. The plug-in cover is firmly mounted on the retaining part 53 by grooves 56.57.

In the mounted state, the hook hole 58 is oriented in the direction of the axis of the tire and is used to receive the coupling member 22.

The identification hook 5 has a substantially constant thickness over its entire length (FIG. 9). At the transition from the holding part 53 to the hook body 59 there is provided a stop f for the connecting member 8.
A protrusion 60 is provided (FIG. 1).

The deflection part 13 is formed by a plug-in part (FIGS. 1O and 11). This plug-in part has at both ends thereof elongate holding parts 61, 62, the cross-section of which corresponds to the cross-section of the spring bar. In addition, the holding part 61,
62 has grooves 63, 64 or 65 on its longer side.
, 66. On the end of the spring bar associated with the holding part 61, 62, there is likewise pressed a plug-in cover, not shown, which is not shown in the drawings, and which ensures a completely secure removal of the holding part by the screw. The holding part connects to the deflection piece 67. The deflection piece 67 widens over half its length (FIG. 10) and in this region the fastening has an annular through hole 68 for the chain 7. The edge 69 of this through-hole is bent concavely with respect to the axis 70 of the through-hole fLl and the side surface 71.7 of the turning piece 67.
2 in an arc. Since the chain is turned approximately 90 degrees by the turning piece 67, the tightening depends on the formation of this edge, and the tightening ensures that the chain 7 is pulled through the through hole 68 without getting caught. It's cold. As shown in FIG. 11, the turning section 13 is bent rL over its entire length, so that the turning section t3tri, is attached to the inside of the curved body 4.
The connecting fittings form an extension of the curved bar.

The inner part l illustrated in FIGS. 1 and 2 can be assembled very easily from the components described above, so that a tire chain of light size can be easily produced.

During tightening, the chain 7 is guided through the guide portions 11a, 12a, as shown in FIG.
It is turned by 0° and is pulled through the through hole 68b.
Ru.

Recesses 81, 82, 84, 85 in the base body 76 are used to secure the casing 87, as shown for the four parts 81, 82 in FIG.

Since the casing 87 fits into the recess, the casing does not come off the inner piece 73.

At its end facing the fixed part 6B, the casing 87 extends beyond the inner part 73b'f to the connecting part 106 (FIGS. 18 to 20). The connecting part 106 is formed into a fork shape and has two legs 107 and 108 facing each other at a distance.
The mutually opposite outer surfaces 109, 110 of the legs 107, 108 are located parallel to each other, and the distance between the legs 107, 108 is such that the inner part piece 73 in the outer region of the connecting part 106

a circular opening 116 for a pivot pin, respectively;
117 is provided, by means of which the inner section 73b can be pivotally connected to the mounting curved rod. This will be explained in more detail using FIG. 31. The lower surface 114 of the protrusion 115 is bent around the axis 118 of the openings 116 , 117 and the casing 87
It transitions in an arc shape to the lower surface 89 of. The arc-shaped surface frame of the coupling surface 113 also extends in a circle around the axis 118.

Both legs to? , the end faces 119 and 120 of t08 are,
The inner part piece 73b is bent in an arc shape (FIG. 20), and as a result, the inner part piece 73b is connected. Even if the inner part piece 73b is displaced from the curved bar piece, the catching of the inner part piece 73b is reliably prevented. .

The openings 116 , 117 transition in the region of the outer surfaces 109 , 110 of the legs 107 , 108 into recesses 121 , 122 which have a larger diameter than the openings. This allows the head of the pivot pin to be arranged recessed in the leg, so that no protruding parts are provided in the area of the leg.

The metal inner section 73 gives the inner section 73b a very high stiffness, so that the inner section does not become damaged, buckled or become unusable during use of the tire chain.

Figures 24 to 30 show another embodiment of the inner piece 73c, which is provided with a hook 5 at one end. Inner piece 73
e can be used in conjunction with the inner piece 73b having the fixed portion 68. The inner partial piece 73e is
Including the guide part, the turning part, and the fixing part, the contour thereof is identical to that of the inner part piece 73b. The inner piece 73c is bent in an arc over its entire length and is provided with a hook 5 at one end and a connecting portion 106c at the other end. The structure of the hook 5 is clear from FIGS. 8 and 9, while the connecting part is similar to the connecting part 106 of the previous embodiment.
It is formed identically to n.

Corresponding to the embodiment described above, the inner part piece has three projections 91c, 102c, 103c which are designed identically to the corresponding projections of the embodiment according to FIGS. 18 to 23.
Equipped with. Each projection has an elongated opening 92e, 104c, 105c in which a pivot member 8 for a running section piece 9 or a cantilever hook can be hung. These openings are located in recesses in the sides of the inner piece, as described in relation to the previous embodiment, and are located in recesses in the sides of the inner section f'1. This prevents the hanging pivot member from moving freely into the inner section. The side walls forming the four parts longitudinally of the inner part form a stop with which the pivot member can come into contact and which can also accept the forces that occur when the pivot member is loaded.

The hook 5 is embedded within the casing 8 by a holding portion 53.

As shown in FIGS. 24 and 26, the web portion 123 extending from the end on the hook side at the protrusion 115C'i of the inner piece 73c has protrusions 91c, 102c, 1.
03c is installed. The web portion 123 is widened in the region of the transition from the projection 91c to the other part of the inner section (FIG. 26). In the plan view of FIG. 26, the extension 124 extends to the outer side of the inner piece 73e.

The expansion portion 124 connects to the side surface 12 of the web portion 123 via the converging side surfaces 125 and 126 on the side of the connecting portion 106e.
Move to 7°128. The end of the web portion 123 forms the upper surface 90c of the inner segment 73c. The width of the lower surface 89c is considerably larger than the width of the upper surface (FIG. 27). The inner partial piece 73c is formed to have a width at least twice that of the n1 workpiece portion 123 formed by expanding in this region (FIGS. 26 and 27). The extension piece 129 is oriented in the direction of the axis of the tire in the mounting condition and is connected to the inner part piece 73.
The protrusion 11 extends from the end on the hook side over almost the entire length of e.
5c'! It extends. The inner part piece is the vertical center plane 101c
(Fig. 27). The extension piece 129 is attached to the jjTj sides 127, 1 of the web portion 123.
28, so that the web portion is spaced apart from the tire when the inner section piece is attached.

Part 1. By opening 92C9104c, 11)
5c is prevented from protruding laterally beyond the inner section 73c, so that the pivot member cannot damage the tire.

The connecting portion 106C corresponds to the embodiment described above, and has both legs 1 parallel to each other, which are formed in the same manner as in the embodiment described above.
07c, 103c (Figs. 28 to 30)
figure). The web portion I23 is widened at the transition to the connecting portion 106c, so that the mutually opposite outer surfaces 109c, 110c of the legs 107c, 108c are located in a plane containing the side surfaces 130, 131 of the expansion piece 129. (Figures 28 and 29).

The inner (1111) section 73c can additionally be provided with a reinforcing insert, which can be formed, for example, from at least one piece of wire, etc. In that case, the inner section has a high stiffness, so that There is no risk of the inner part being damaged during use.

In the embodiment according to FIGS. 1 to 17, the mounting curved body 4 has a spring wire with a particularly rectangular cross section. The advantage is that, instead of a hook, it is possible to use a longitudinal chain ring as the pivot element, which is also used for the running part and is fixed directly on the spring bar without a screw. The advantage of using a spring wire with a rectangular cross section is that, compared to the case of using a spring wire with a circular cross section, the mounting can significantly increase the spring force that causes the curved body 4 to become annular. . In that case, the mounting involves bending the curved body 4 upwards and ensuring that, after mounting the tire chain on the tire, the inner part l returns elastically to its annular starting position. In each of the above embodiments, the tightening is such that the chain 7 is fixed by one end at the fixed part 6, 6a.

It is of course also possible to fasten the chain to the inner part at a distance from the end of the inner part, without impairing the advantageous attachment of the tire chain. The aforementioned guide portions 11, 12.

Instead of 11a and 12a, it is also possible to provide a guide portion configured in a different manner, and as shown in FIGS. 12 to 3.
It is also possible, as in the embodiment of FIG. 1, to form such a guide part integrally with the inner part -! 1 to 11, or as a separate component which is additionally attached to the inner part. Thereby, existing tire chains can also be additionally equipped with a guide section. On the other hand, the guide part must be formed so that the locking chain can easily slide through the guide part. Similarly, the turning part 13 of the inner part also has a separated part (the first part).
It is also possible for the inner part to be formed in one piece (FIGS. 12 to 31).

FIG. 31 shows a mounting curvature 4d which is designed to be foldable, so that the tire chain can be folded, packaged and stored very compactly. This mounting curve has inner pieces 73e and 73b. Such a mounting may be provided in place of a curved body, or the mounting shown in FIG. 1 may be provided instead of a curved body. The free ends of the curved rod pieces 132, 133 are inserted into the connecting parts 106c, 106,
and leg portions 107c, 108c; 107, 101
3 through the openings 116, 117 of the curved bar and through corresponding openings in the free end of the curved bar. There is. Similarly, the curved rod pieces 132 and 133 are
At the other end, a connection part 106 between the cylinder inner part pieces 73c and 73b
c, a connecting part 136 formed identically to 106;
, 137'i. Double curved bar piece 132°133
is connected to both curved rod pieces 13 via pivot pins 139 and 140.
2, another curved bar piece 1 pivotally connected to 133;
They are connected to each other by 38. Accordingly, the mounting curved body 4d is composed of five curved rod pieces, each of which is pivotally connected to one another. Therefore, the installation of the curved body 4di can be folded into a very small size, so that the tire chain does not take up much space. Connection part 10
The ends of the individual curved rods that engage between the legs 107 , 108 of 6 are provided with end faces whose shape is adapted to the configuration of the coupling surface 113 . In addition, in the state of use illustrated in FIG. 31, the curved rod pieces lie abutting each other with their cross sections lying radially V relative to the through hole for the pivot pin; As a result, the cross section of the curved bar forms a stop in this state. Therefore, the curved rod pieces that engage with each other do not deviate from the state shown in FIG. 31. Furthermore, the curved rod pieces (!) that engage with each other can be locked in the final state by means of a locking joint. On the inner surfaces Ill and 112 of both legs 107 and 108 of the connecting portion 106 are cap-shaped raised portions 141.
, 142, and this ridge can be provided with a corresponding locking recess in the end of the curved bar to be connected. If both curved rod pieces are secured, the leg 10
7, 108 engage in these recesses by locking ridges 141, 142, resulting in additional locking of the curved bar in the final state.

The curved rod pieces 132, 133, and 138 are the inner one-piece pieces 73b.

73c, and has a projection provided with an elongated opening for hanging a pivot member 8 or a cantilever hook for the running section 9.

It is also possible for the tire chain mounting curve to consist of fewer or more curved bars. The tire chain can also be folded into a smaller size if the mounting is made up of only two curved rod pieces that are pivotally connected to each other. Of course, it is also possible to elastically expand the curved body 4d from the illustrated flat annular state, and as a result, the curved body 4d can be easily mounted on the tire.

In the illustrated and described embodiment, the clamping chain 7 is turned 180 DEG in the connecting member 22 and the clamping chain 7 is guided back to the curved bar piece to which one end of the chain is fixed.

Of course, after tightening the chain, turn the connecting member 22 again to 180 mm.
It can then be guided back along another curved bar piece VC and turned into the outer part of the tire chain. Even with this configuration, the tire chains can be completely attached until the vehicle is stopped.

This invention! In the tire chain based on L, the traveling part 2 has the following:
Although there is a chain ring in the running part, the clamp has no parts provided to deflect or guide the chain, thus providing very quiet running. - Also, there is no risk of such parts being damaged by being trampled by tires. Furthermore, the tightening does not cause the chain to be tightened in its guide part. The guide and turning parts for the tightening chain do not come into contact with the road surface, so there is less wear.

For tightening, the chain 7 can be easily pulled through the guide and deflection parts, so that the tire chain can be tightened easily. After spreading the tire chain on the ground or holding it by hand, it is only necessary to hold and spread the mounting curved body 4.

In the embodiment of FIGS. 1 to 1f, the hook 5 and the fixed part 6 are formed in such a way that the pivot member 8 or the cantilevered hook in this area can come into direct contact with the projection 60 and the flange 47. I'm here. By means of this mechanism, the running parts which are hung on the pivot parts of the hinges and which are directly adjacent to the locking parts 5, 22 can be arranged at a small distance from each other, so that the running parts in this area are The width of the gap No. 2 is approximately equal to the width of the gap in other areas of the running portion.

In particular, this allows the width of the running part gap to be kept relatively small in the region of the inner locking parts 5, 22, so that wear of the adjacent running part 9 is reduced.
