Definitions

  • the present invention relates to a tensioning and locking device, in particular for snow chains.
  • Known tensioning and locking devices for snow chains are fixed at two points, namely at one end of the outer chain and at one end of a transverse chain, and are provided with a flexible traction cable wound about a spool and elastically engaging the other end of the outer chain.
  • levers and pushers which, depending on their position, enable the cable to be pulled to connect the two ends of the chain together, prevent its further exit to ensure chain tensioning, and lock this tensioning configuration.
  • An object of the invention is to eliminate these drawbacks by providing a tensioning and locking device which can be operated easily and comfortably.
  • Another object of the invention is to provide a device which enables the degree of tensioning to be maintained constant even following settling during vehicle travel.
  • Figure 1 is an exploded perspective view of the device of the invention
  • Figure 2 shows in it plan view during extraction of the traction cable
  • Figure 3 shows it during retraction of the traction cable.
  • the tensioning and locking device comprises substantially a casing 2 closable by a cap, not shown in the drawings, and provided with two rings 4 to which the end of the transverse chain and the end of the outer chain of snow chains are fixed.
  • the casing comprises in its lateral surface a slot 6 for passage of a traction cable 8 fixable to the other end of the outer chain.
  • the traction cable is secured to a spool 10 housed in the casing 2.
  • a helical spring 12 is inserted into the cylindrical cavity of the spool 10 and has its inner end secured to a slot 14 provided in the casing and its other end engaged in a tooth 16 provided on the inner lateral surface of the spool.
  • a ring gear 18 With the spool there is associated a ring gear 18 the teeth 20 of which are elastically engaged by a first retention pawl, indicated by 22, pivoted to the casing on a pin 24.
  • the head of the retention pawl 22 engages in a seat 26 provided on a rotatable member 28 pivoted on a pin 30 rigid with the casing 2 and provided with an operating lever 32.
  • the second retention pawl 34 is housed in a seat 38 provided in the member 28 and is rigid therewith by virtue of the presence of a spring 40 having one end 42 housed in a seat present in the member itself and acting at its other end 44 on the retention pawl 34.
  • the device of the invention operates in the following manner: after fixing the ends of the inner chain and positioning all the transverse chains across the wheel, the lever arm 32 is rotated clockwise (with respect to Figure 2), after elastically disengaging an appendix 46 from a tooth 48 provided on the casing 2 and elastically engaging an appendix 58 with a tooth 60.
  • the retention pawl 22 rotates anticlockwise about the pin 24, against the elastic action of a spring 50, and disengages its teeth 52 from the teeth 20 of the ring gear. While in this configuration the tooth 36 of the retention pawl 34 interferes via its active flank with the teeth 20 of the ring gear 18, but does not hinder clockwise rotation of this latter as it can rock about the pin 32 against the elastic action of the spring 44.
