Definitions

• the invention relates to an anti-skid device for vehicle tires, with two circular rings and an anti-skid chain arranged between them and connected to the two rings.
• the task was to create an anti-skid device which has the smallest possible weight and a space-saving shape for being carried in the trunk, which can be carried out by a single person without any special effort, with as few simple handles as possible, without the aid of assembly means
• the application of power can be reliably mounted on the tire and can be easily detached from it without getting dirty.
• the most space-saving are anti-skid devices which are formed only from chain links and a corresponding tensioning device. Such anti-skid devices are known for example in CH-PS 495'858 and 558 * 263. To avoid tangling of the chain parts,
• the aim of the present invention is now to eliminate this gap, to make the rear retaining ring free of movement and elastically flexible, so that it can be brought over the wheel faster, more securely and with considerably less force, with an automatic ring leadership is achieved and at the same time the front retaining ring assumes its correct position.
• FIG. 3 shows the anti-skid device mounted on the tire, seen from the front
• FIG. 4 shows the hook closure according to FIG. 2 on a larger scale
• Fig. 5 hooking into the eyelet, as a floor plan to Fig. 4, and
• the anti-skid device shown has a coming to the rear tire flank (Fig. 2), the open, expandable, circular ring 1 and NEN coming to the front tire flank (Fig. 3), circular ring 2.
• Both rings 1, 2 are made of non-rusting, resilient round steel, the wire rod of which is 5-10 mm, depending on the type of vehicle.
• the rear ring 1 has two free ends. One end forms an inward curve 3a located in the circular plane, which can be formed at right angles (FIG. 1) or as an eyelet. The other end 3b overlaps one ring end i of the circular plane by about 1/6 of the circumference and bears a screwed-on locking device 4 compared to the bend 3a (FIGS. 1, 2).
• a second locking device 5 is attached diametrically to the first locking device 4.
• the front ring 2 can be provided for larger tire diameters such as the rear ring 1 open with a bend 3a and a locking device 4.
• the front ring has a one-piece, closed design. In both cases, the ring 2 carries a lateral locking device 6 at the diametrical points of the horizontal medians (FIG. 3). Between the two rings 1, 2 (FIG. 1) there is one
• Flange chain 7 arranged as an anti-skid chain and connected to the two rings 1, 2 by means of holding elements 8 which can be slid like curtains and cannot be detached in the radial direction.
• 1 on the rings 1, 2 hanging holding members 8 are U-shaped round bars, the two ends of which are bent in the normal plane to the U-plane such that the holding members 8 in the rings 1, 2 easily slidable, but in radial direction are permanently connected to the rings 1, 2.
• ring-shaped members can also be provided.
• the chain strands 7a are drawn disproportionately distorted in FIG. 1.
• the ends of the rear ring 1 come down during assembly (FIGS. 1, 2).
• the bend 3a and the opposite locking device 4 of the rear ring 1 form elastically movable stops for the mutually facing parts of a hook closure 9, 10 (FIGS. 1, 2, 4 and 5).
• This has an eyelet part 9 and a corresponding hook part 10, the eyelet and the hook forming the mutually facing ends of a round steel rod 11 bent concentrically to the ring 1 (FIGS. 4, 5).
• At least two sliding members 8 slidable on the ring 1 are welded onto these rods 11.
• the lock 5 diametrically opposite the hook lock 9, 10 (FIGS.
• the anti-skid chain 7 is releasably attached to the front ring 2 in the mounting position (FIGS. 3, 6) at the bottom by means of two suspension brackets 12. These have omega-like steel rods 13, the middle part of which serves as a handle and whose leg ends are welded to a special holding organ 14.
• These four holding members 14 are just in case formed from U-shaped round steel bars, the two ends of which are bent in the normal planes to the u-plane such that these holding members are slidable in the ring 2 but can be snapped in the radial direction with force in this ring 2 and by
• the two suspension brackets 12 have bends 15 at the end parts.
• Two elastic tension members 16 are provided for pulling and securing the two suspension brackets 12. As such, a loop (FIGS. 1, 3 and 6) made of rubber or a helical spring provided with hooks can be provided.
• Each tension member 16 is permanently attached to the holding member 14 on the stop side of the suspension bracket 12 with an * attached ring 16a and can be attached to the protruding bend 15 of the other suspension bracket.
• These two suspension brackets 12 make it easier to open the anti-skid device.
• traction elements * 16 can also be attached to the ring stops ' .
• a wheel flange chain (FIGS. 1-3) or a ladder chain can be provided as the anti-skid chain 7.
• a lateral connecting means 17 is provided on the front ring 2, since the holding member 14 without the holding ring 16a of the one hanging bracket 12 leads via all holding members 8 on the ring 2 to the adjacent holding member 14 of the other hanging bracket 12 and with all of these Holding members is firmly connected (FIG. 3).
• an additional connecting means 17 is required, which on the rear ring 1 extends from the holding member 8 projecting from the hook via all holding members to the holding member 8 of the hook closure 9 projecting from the eyelet. 10 leads and is firmly connected to all these holding organs 8.
• a connection means 17 can be a small-scale
• Chain a cable or a rubber belt can be provided. It serves as a safety device in the event of a chain strand 7a breaking, which causes an undesired displacement Holding members 8, 14 on the rings 1, 2 would result.
• the fastening of the overlapping ring end 3b to the other ring end part can be provided with a releasable clamping member 18 (FIG. 4). This can be attached, for example, to the hook closure 9, 10 or to the nearby suspension bracket 12.
• the anti-skid device according to FIG. 1 is spread out on the floor, so that the rear ring 1 comes to lie close to the wheel tires and the closure parts 9, 10 are pulled back over the ring half. Then the ring 1 is opened with both hands by spreading and placed under the tire. ' The ring 1 is then erected in such a way that the clamp 5 comes up and the ring ends come to lie down. The ring 1 is then put back over the tire. The hook parts 9, 10 slide down on the ring 1 against the stops 3a, 4 (FIG. 1).
• the two suspension brackets 12 are then pulled towards one another by hanging the tension members 16 against one another, so that they abut the stops 3a, 4.
• the anti-skid device is thus ready for operation and no longer requires re-tensioning. All previously known designs require this cumbersome manipulation after a few hundred meters.
• the anti-skid device is removed, the traction elements 16 are first detached from the front ring 2 and the suspension brackets 12 are pulled out of the ring 2.
• the hook fastener 9, 10 is then opened, the two
• the anti-skid device described can never get tangled thanks to the detents, is easy to accommodate in the trunk and is immediately ready for use.
