Safety chain for vehicles.

The present invention relates to safety chains for use in vehicles that are on snowy or snow-covered roads ride on frozen ground.

Various types of chains are currently known for the aforesaid application, all of which include some of the following Have shortcomings:

- You need a lot of space both when you take it off and when you put it on.

- They result in a broken lane.

- Putting on and taking off are inconvenient and costly.

- They attack poorly on the ground and therefore allow only trips at low speeds.

In order to remedy these deficiencies, the chains were made according to Innovation created, which have the following advantages:

- They take up little space after dismantling and after attachment they also form projections the dimensions of small size wheels.

- They can be attached and removed quickly and easily.

- They give you the best grip on the ground and therefore enable you to travel at a higher speed than that usual.

- The resulting lane is because of its small Size steadily and does not make any leaps.

The safety chains essentially consist of a number of independent and interconnected elements, each of which represents a punched and folded sheet metal, the one of the profile of the (Tire) ceiling has adaptable shape, which after a Part of an arc of a circle of approximately at least the same diameter as the ceiling is extended; at the junction of both parts there is a

drilled eyelet through which the circular section of the adjacent element (chain link) runs, with this section is provided with a projection which prevents the separation of the successive chain links .

There are two outer parts that serve to connect with each other to close the whole, which have some modifications compared to the arrangement mentioned for the others; one of them instructs its round section has a toothed edge and is embedded in a groove (groove) in the section is worked, which includes the ceiling of the link located at the other end of the whole. This groove will captured by a locking mechanism that is operated by a normal screw with an external recess in its head is attached, in which an operating key is inserted, while the locking mechanism is activated by the action of a finger is released or stopped, which is located at the end of a piston surrounded by a spring, so that the Head of the piston is accessible from outside the wheel.

All links are linked to the neighboring ones by chain pairs united, connected by central crossbars which serve to hold apart the chains of each pair; the outer sections are missing the chains.

To supplement the above description and only two

For the sake of play, drawings are attached here, namely show

Fig. 1 is a diagram of the members (elements);

Fig. 2 is a schematic diagram of the outer links prior to their assembly;

3 shows a section along line III-III of FIG. 2; 4 shows the removed safety chain; Fig. 5 attached chain.

Each of the links is formed from two parts, namely from a part 1, which comprises the wheel profile, and from a second part 2, which has the shape of an arc of a circle and which is in connection with the same Parts in the remaining links forms a circle, which is approximately with that of the smaller diameter of the Ceiling (see Fig. 5) matches; at the intersection of the two sections 1 and 2 there are drilled eyelets 3 which are each penetrated by the section 2 of the adjacent link, and are located at the ends of the sections 2 the projections 4, which prevent the separation of the connected ends; the sections 1 each link are connected by the chains 12 with the corresponding sections of the adjacent links

united, with the exception of the ends, which do not go through Chains are connected. Of these chains 12 there are two in each space and they have intermediate cross bars 13, which ensure a constant distance between each pair of chains 12.

To attach the whole, it is sufficient to put the links with their parts 1 around the wheel profile and the pull together outer ends, the portion 2 of which is inserted into the groove 6, so that the locking mechanism by action is released on the piston 11 via its head 9, whereby the finger of the piston 11 is withdrawn and the lock 7 is released; the toothed edge 5 slides over the teeth of the locking mechanism 7 over and over again when the head is released it is blocked, causing the finger to lock through the action of the return spring Io causes; then you can tighten the whole thing in an appropriate way by inserting a key into the recess of the head of the axle 8 and, if necessary, tighten.

To remove the device, it is sufficient to insert the key into the head of FIG. 8 in the form indicated and its rotation in the opposite sense, i.e. loosening, thereby separating the end links from one another and the device can be removed.

Claims

Claims (4)

Claim e (ι 1.J safety chain for vehicles, characterized in that they consist of a number of mutually couplable links, each of which is formed from a bent, two sections (1,2) forming thin flat iron, one of which is the profile of the tire cover and the other is connected to the other parts corresponding to it (1, 2) so as to form approximately a circle adjacent to the outside of the wheel, the successive links being connected by pairs of chains (12) and each of the links in in the middle has a drilled eyelet (3) through which the round section (2) of the following link is passed, which in all cases is closed by a protrusion (4) that prevents its separation from the neighboring links and from which the one on the round part (2) has a toothed edge (5) and the other on locking mechanism (7), which enables the whole to be closed and tensioned. 2. Safety chains anach the preceding claim, characterized in that the drilled Eyelet (3) of each link are located at the intersection of the two of the formed sections (1,2). - 7 609 8 2 3/0269 3. Safety chains according to the preceding claims, characterized in that each Chain pair (12) is connected to one another by a cross bar (13). 4. Safety chains according to the preceding claims, characterized in that the to be applied to the wheel profile and to one of the outer links The associated section (1) has a groove (6) in one of its lateral eyelets in which a locking mechanism (7) arranged with an axis of rotation with a recessed outer head (9) for mounting a key which actuates this is, wherein this locking mechanism (7) can be locked by means of a head surrounded by a spring (lo) which an outer head and a locking finger (latch) provided inner end (11), and the locking mechanism (7) is used at one of its places the toothed Edge (5) of the round portion (2) of the limb of the other end of the device can hold. 609823/0269 Blank page
