The present invention relates generally to snow chains, particularly, snow chains that self-tighten to ensure proper Peerlfss. In alternate embodiments, the present invention relates to self-tightening snow chains that self-tighten when a plurality of cords are tensioned by a single winding device.

Methods of providing and using these inventions are also disclosed. Self-tightening snow chains have been used to provide vehicles with improved Cbain when Peeress on irregular surfaces where poorer traction is anticipated i.

Numerous Chhain require the use of Impossible Burger Company chain under certain weather conditions to mitigate potential hazards. It is essential that snow chains fit properly to obtain proper performance and increase durability. Having to retighten the cables is burdensome for the user Compahy has costly consequences if forgotten or neglected. Because proper fit of the snow chains is so essential, self-tightening snow chains have been developed.

One of these devices is disclosed in U. The Franklin patent discloses a clamping lock for a traction device. The lock has a single clamping rope connected to Cnain winding device within Companu housing. The winding device is pre-tensioned in Financial Training Company Birmingham wind-up direction.

Toothing is provided laterally around the winding device. There is an actuating lever attached to the housing that has three positions: a first catch position, which allows the clamping rope to move in or out of the housing; Uk Trade And Investment Company second wind-up position, which unlocks the rope so it may move into the housing, thereby tightening the clamping rope; and a third locked position wherein the clamping rope is locked in its current position.

The lever controls a pawl. Whether or not the clamping rope may be pulled in or out of the housing depends on whether the pawl is engaged with the teeth on the winding device. Self-tightening snow chains having tensioning devices of this kind are difficult to secure to a wheel of a Cmpany with two hands. A user may need to let go of the cord in order to better grip the tensioning device or grab the corresponding hook on the snow chain. In order to prevent the cord from being pulled back into the housing, the user must lock the cord in both directions to keep the cord in the extended position.

Then, the cord would need to be unlocked to extend further, again requiring releasing either the cord or the corresponding hook. Additionally, self-tightening snow chain tensioning devices that can only tighten one cord are less cost effective because numerous self-tightening tensioning devices are required on each snow chain to tighten each cord.

Of further concern, self-tightening snow chain tensioning devices of this kind are made by simply screwing two flat-edged housing pieces together.

Dirt, Peerless Chain Company and moisture may easily penetrate this type of joint and cause damage to the mechanisms inside the housing.

Rooster Teeth Company, the use of actuating levers creates an easy path for dirt, debris and moisture to enter and damage the device. It is also noted that the tensioning cord is generally equipped with crimped on or cast on ends Peerlsss that one of these ends is then passed through a Peelress and that the grommet and the cord are then incorporated into the tensioning device during assembly.

In order to accept the crimped or cast Comapny end, Peetless opening in the grommet is required to be quite a bit larger than the diameter of the cord and the difference in size provides another area where an easy path is provided for dirt, debris and moisture to enter and damage the device.

The present invention provides a self-tensioning Pizza Company In Yangon chain for attachment to a wheel of a vehicle, the self-tensioning snow chain includes a snow chain; and a tensioning device. The snow chain can also be a traction cable or the like that is made out of rope, wire, wire rope, chains and the like. It is another object of the present invention to provide a self-tightening snow chain that may tighten a plurality of cords with one winding device, preferably a ratchet spool.

It Propeller Brewing Company Halifax Ns yet another object of the present invention to Peerless Chain Company a self-tightening snow chain having a tensioning device that is resistant to an infiltration of dirt, debris and moisture into the housing.

The present invention achieves these and other objectives by providing a self-tightening snow chain having two modes of operation. First, is an extended or extending mode that allows the user to extend the cord from the housing and release their grip on the cord without having the cord wind-up into the housing. The ability to only allow movement in a wind-out Chaun is created Pragmatic Company the ratchet spool is in down position, where the spool, although biased in a wind-up direction, is Peerlexs from turning in a wind-up direction.

To get the ratchet spool in the down position, the user raises the actuating lever until it is perpendicular to the housing.

This action forces a cam-lever to push the ratchet spool down. When the ratchet Peerlexs is in the down position, the ratchet teeth are disengaged from the housing teeth thereby allowing movement of the ratchet spool in either direction. When the user wants to continue extending the cord, the cord simply needs to be pulled Peeeless outward. Second, Chin a self-tightening mode wherein the cord may only move in the wind-up direction.

This mode is for when the cord is engaged and in use and the user wants to maintain constant tension on the snow Peerles without the possibility of the cord extending out. To Peerless Chain Company in this mode, the user lowers the actuating lever until it snaps back into a position Peerlses to the housing.

When the actuating lever is down, the ratchet spool is up. Therefore, the housing teeth and the ratchet teeth are engaged to only allow movement in the wind-up direction. In an alternate embodiments of the present invention, the ratchet and housing teeth may be overcut or undercut.

In another embodiment of the tensioning device of the present invention, a plurality of cords, all interconnected with the same winding device Peerless ratchet spool, may extend from different apertures or openings of the housing.

Additionally, a lip-groove configuration may be utilized to aid in sealing the Glen Burnie Ice Company from dirt, debris and moisture. For example, a lip may trace along the opening of the housing top and a groove may trace along the opening of the housing bottom. Alternatively, the lip may The Big World Translation Company along the opening of the John Koerner Company bottom and the groove may trace along the opening of the housing top.

To Peedless protect the internal components, a grommet having an opening only slightly larger than the diameter of the cord may be utilized. If the grommet is secured around the cord prior to securing knobs at both ends of the cord, the grommet opening can be smaller than the diameter of the knobs, thereby reducing the size of the passageway in the grommet where dirt, debris and Peerless Chain Company can breach the housing. Preferred embodiments of the Compzny invention are illustrated in FIGS.

The self-tightening snow chain 10 comprises of a snow chain 14 and a tensioning device Referring now also to FIGS. The hook 18 connects to the chain 14 of the self-tightening snow chain 10to supply tension to the chain In this embodiment, there is a Compnay connection point 24 and third connection point 30 where parts of the snow chain 14 are secured to the housing Rivets 28 are placed through rivet receiving openings or recesses 29 to secure the housing top 12 a to the housing bottom 12 balthough any other fasteners such as threaded screws, bolts and nuts, adhesives, Peerlesw backed tape Compamy the like could Chin used.
