  • the known device has a holder with a recess for receiving a nose of a bolt. Furthermore, an actuating lever which is rotatably mounted on the bolt is provided in order to bring the bolt into a fixing position.
  • US 2 802 248 A relates to a lashing and holding device.
  • This device has a bolt with teeth that is slidably mounted in a housing.
  • the bolt can be releasably fixed again by means of pawls which cooperate with the teeth and are arranged in the housing.
  • the FR 2 483 333 AI relates to a train and fastening device in which a gear is provided which can be fixed by means of a pawl, whereby a fastening element cooperating with the gear can be tensioned.
  • the known device has a double-strand link chain with anti-slip bars arranged between the strands and carrying spikes.
  • the anti-skid bars are arranged on bracket bearings.
  • a tensioning bracket is arranged for fastening the anti-skid device on a tire, and at the other end of the chain, a locking bracket is provided for automatic locking with the tensioning bracket.
  • the clamp is fixed to the tire by means of a clamp lock, for example by means of a screw connection or a toggle. After approximately one turn of the wheel, the clamp lock must be released so that it cannot rub against the tire while driving.
  • the known solution has the particular disadvantage that, depending on the design, parts of the tensioning device or the entire tensioning device must be removed after the chain has been put on, as a result of which the ease of use of the known anti-skid device is significantly reduced.
  • DE 25 53342 AI discloses a snow chain for motor vehicle wheels.
  • the known snow chain has side strands and transverse elements running between them.
  • To fix the snow chain to a tire there are clamps, each with two clamps, which can be brought into a closed position.
  • Locking elements are provided for moving a clamping hammer into an open position. These consist of tongues which are punched out on three sides from a clamping bracket and are integrally connected with their base to the clamping bracket. These tongues are designed such that they protrude from their cutouts in the closed position of the fixing device and assume a flatter position than the tensioning bracket in a closed state. When the clamping bracket is spread by pressing the gripping brackets apart, the tongues press against the end faces of the cutouts and thus keep the gripping brackets in a spread state.
  • a disadvantage of this known embodiment is, above all, that during the disassembly, the gripping bars have to be pressed apart in order to be able to release the tire from the clasping of the fixing device, which means that the snow chain is less easy to use. Furthermore, due to the contamination of the snow chain occurring in practical operation and the need for dismantling to encompass both gripping arms and pull them away from one another, there is a high risk of contamination for a user of the snow chain.

  • the catch lock is only activated in the assembled state and can therefore only be locked with the catch lugs 24a, 24b.
  • the catch tabs 24a, 24b can be released or unlocked again by an externally activated longitudinal movement of the spacing and thrust fixation 26. Furthermore, the rocker arm 21 can be folded down. Simultaneously with the rocker arm 21, the stabilization web 3a, 3b also slips out of the eyelet 22, whereby the locking of the anti-skid device is released.
  • a separate spacing or thrust fixing device 26a, 26b can also be provided for each catch lock Fa, Fi. Whether one or two spacer or shear fixing device (s) are used depends entirely on the application and the installation of the anti-skid device.
  • the anti-skid device can be placed on the floor in front of or behind a vehicle wheel. The selected front or rear wheel is then driven lengthways over the modular anti-skid device. The anti-skid device is mounted ready for use after one complete wheel rotation. For safety reasons, a brief visual inspection of the anti-skid device can be carried out after the automatic assembly.
  • the joints 9a, 9b of the gripping and clamping bracket modules 1, 2 can be struck with an impact tool, for example a urine a metal rod or a screwdriver, can be opened and unlocked.
  • an impact tool for example a urine a metal rod or a screwdriver
  • the spring bolt 23, the locking knob or nose 24 can also be unlocked with the help of the thrust fixing device.
  • at least one wheel revolution is driven.
  • the modular anti-skid device detaches from the wheel and is placed on the ground. The anti-skid device is dismantled.

Abstract

L'invention concerne un dispositif de verrouillage pour une articulation tournante (3) reliant un étrier de prise (2) et un étrier de tension (1) d'un dispositif antidérapant. L'invention est caractérisée en ce qu'un élément de fixation (8, 10, 12, 16) soumis à une précontrainte est monté au moins sur l'étrier de tension (1). Dans une position de fixation, dans laquelle l'articulation (3) est bloquée, cet élément de fixation appuie contre une section de retenue (3b) de l'étrier de prise (2) et il est maintenu en position de fixation par la force de précontrainte.
