Description

The present invention relates to a double chain of a non-slip body attached to an automobile double tire.

Conventionally, as an automobile tire double chain, the diameter of a total of three rows of chains, that is, a front edge row chain, an opposite surface edge row chain, and a back surface edge row chain, is smaller than that of a tire. One type has a plurality of three rows. It is a double chain formed by connecting with the same horizontal locking chain at each location, and the other type is a horizontal locking chain between the facing surface edge row chain and the front edge row chain and the back surface edge row chain on both sides. Is a type that is connected in a staggered manner at regular intervals.

In the conventional automobile tire double chain, in two types, the diameter of the chain in three rows is smaller than that of the tire, so that each of the fasteners provided on the chain pieces forming both ends of the chain in three rows There were many inconveniences as follows in the work of fastening and the work of removing the fasteners that were fitted together.
(B) As a double tire, there is a tire wheel that is provided with both outer and inner tires, and the width is almost the same as the tire width, but a circular protruding convex part is provided in the middle of the tire wheel.
The space between the outer and inner tires is the space between the protruding and convex parts, and the work is done while being aware that it is narrow enough to accommodate an adult fist.
(B) There are two ways to install the double chain. The first is that the two types of double chains work in the same way, with three rows of chains on the upper surface of both the outer and inner tires. Each end of each stopper provided on the chain piece forming both ends of the three rows of chains is placed on both sides of both tires, and is provided on the chain piece forming both ends of the facing surface edge row chain, which is often troublesome. Start with the fastening of each of the fasteners, and pull out one end of the stopper from one side to the other side with your hand or with a pull-out rod, but you can not pull out any, and it is narrow enough to fit an adult fist. Difficulty comes out in fitting the fasteners.
(C) The front edge row chain and the lateral locking chain, and the back surface edge row chain and the lateral locking chain are brought closer to the opposite surface edge row chain to face each other because both hands can be used and the fastening can be easily performed if the position is reached to the field of view. It is pulled out integrally with the face edge row chain, but it is pulled out where it can be reached due to the difficulty that each lateral locking chain is caught on the tire surface and the groove, but at both ends of the stopper Since the hand to make the stop hides the stop, the stop is made with the feeling of groping.
Also, try to increase the length to be integrated with the facing surface edge row chain, and if it is too much, each row chain and the lateral locking chain will be integrated, and it will slide from between the outer and inner tires to the protruding convex part of the tire wheel. It is a place to be careful because it will fall.
(2) Next, proceed to the fastening work of each of the fasteners provided on the chain pieces forming both ends of the back surface edge row chain, and move to the facing surface edge row chain by the fastening work of the fasteners of the facing surface edge row chain. Put back the front edge row chain and the back edge row chain and their respective lateral locking chains, and lie down under the car body or put your hand on the back side of the inner tire in a half-body posture on the side, and both the outer and inner tires If you can reach the position of the stoppers placed down on both sides, the stoppers are fastened, but in the fastening work of the stoppers of the facing side edge row chains, each row chain and each lateral locking chain are moved. If so, it may have moved to a position that is out of reach.
(E) In order to return both ends of the stopper to a position where it can be reached, each row chain and each lateral locking chain are moved from around the surfaces of both the outer and inner tires, but the facing surface edge row chain is formed. Because there is little gap with the tire surface and the weight of the iron material is added, it can be moved only little by little, so it is easy to stop the stopper by moving the car body, but since it is not in the field of view, the position is decided by repeated operation , The fasteners are fastened together.
(F) Next, proceed to the fastening work of each fastener provided on the chain piece forming both ends of the surface edge row chain, and if the stopper is in a position where it can be easily stopped, pull both ends of the stopper and fasten them. And finish the installation work.
(G) In addition, to fasten the fasteners of the surface edge row chain of the type of double chain in which one type of lateral locking chain is connected in a staggered manner at regular intervals, the vehicle body is moved. , Step on the lateral locking chain on both the outer and inner tires, determine the position where the stopper is easy to stop, pull both ends of the stopper together, and finish the installation work.
(H) Second, in the two types of double chains, the work method is the same, and on the ground on either side of the direction in which both the outer and inner tires rotate, three rows of chains are extended and sideways. Spread the chain to the width of both the outer and inner tires, move the car body on it, step on both the outer and inner tires, and place it in the extended middle position to form both ends of the three rows of chains. One end of each stopper provided on the chain piece is located on both the outer and inner tires.
From one side of one side, lift one end of the fastener, each row chain and the lateral locking chain to the upper surface of both the outer and inner tires and cover them, and from one side in the same way, one end of the stopper, each row chain and the side The locking chain is lifted and covered on the upper surfaces of both the outer and inner tires to prevent it from slipping off the tire surface, and the fasteners on the facing edge row chain are fastened.
(I) Even when fastening the fasteners, the movement of the hands and fingertips is poor due to the narrow space between the outer and inner tires, and the fender part obstructs the field of vision, so you can grasp the part of the stopper with the feeling of groping. However, in snow or in places with low temperatures, the iron material is cold and difficult to fasten both ends of the stopper.
(N) Next, proceed to the work of fastening each of the fasteners provided on the chain pieces that form both ends of the back edge row chain, and move the vehicle body to make the position of the stopper easy to stop, so the front surface Temporarily fix each stopper provided on the chain piece that forms both ends of the rim chain, but the driver's seat does not allow the field of view to enter, and the operation is repeated to determine the position of the stopper and lie down under the vehicle body. Or put your hands on the back side of both the outer and inner tires from the half-body posture on the side, and bring both ends of the stopper together to fasten them together.
(L) Next, proceed to the work of fastening each of the fasteners provided on the chain pieces that form both ends of the front edge row chain, move the vehicle body to a position where it is easy to fasten the stoppers, and work on the back edge row chain. Finish the installation work with the temporarily fixed fastener as the final stopper.
(E) In the first and second operations of attaching the double chain, it is difficult to fasten each of the fasteners provided on the chain pieces forming both ends of the facing edge row chain, so the fasteners If it is difficult to reach the touching hand, you can often use your bare hands by adjusting the feeling of your fingertips to grasp the stopper. For work in snow or in extremely cold places, you can use gloves to stop and work quickly. I strongly hope for a way to finish it comfortably.
In the second work, even if the double chain is placed on the ground and both the outer and inner tires are placed, the thickness of the lateral locking chain creates a stopping effect on the tires, and the driving operation is to rotate the tires strongly to get on. Then, on snow or ice surface, the horizontal locking chain and the chain of each row wheel slip and escape, and the work of re-laying it is difficult to bite the body and hands in snow and cold.
(W) In the work of removing the double chain, the work method for the two double chains is the same. First, remove the stopper of the back edge row chain first, and then remove the stopper of the front edge row chain. I would like to make a slack in the facing edge row chain and each lateral locking chain, and remove the fasteners on the facing facing edge row chain, but since both the outer and inner tires are stepping on the lateral locking chain, the surface Even if the fasteners on the edge row chain and the back surface edge row chain are removed, the facing surface edge row chain cannot be loosened, and the operation of moving the vehicle body is repeated to release the contact between the tire and the lateral locking chain to create looseness. This is the facing edge row chain where the stopper of the facing edge row chain must be removed.
In addition, there is an inconvenience that the stopper is located on the ground during the removal work, and if it cannot be removed, the vehicle body is moved to a position where it can be removed. If there is one diagonal stop, I hope that I can reach it, and finish the removal work.
The present invention has been invented to solve the above problems.

The diameter of the front edge row chain, the facing surface edge row chain, and the back surface edge row chain is smaller than that of the tire, and one type has the same horizontal locking chain at multiple locations in three rows. The other type is a double chain formed by connecting with, and the other type is that the lateral locking chains of the facing surface edge row chain and the front edge row chain and the back surface edge row chain on both sides are staggered at regular intervals. It is a type that is connected by a shape, and in such a double chain,
In addition to each of the fasteners provided on the chain pieces forming both ends of the three rows of chains, another fastener, that is, an intermediate fastener, is provided in the middle of each row of chains, and the surface edge thereof is further provided. In the intermediate fastener of the row chain, connect the position of the chain piece just before the intermediate fastener recess and the intermediate fastener convex facing this intermediate fastener concave with a connecting chain of a length with a little margin. Therefore, it is characterized in that a connecting gusset chain is provided.
It is an automobile tire double chain having the above configuration.

The installation process is the same for the two types of double chains, in the middle of each row chain, which is provided separately from the respective fasteners on the chain pieces that make up the ends of the three rows of chains. Start by covering the other fastener, the intermediate fastener, with the upper surface of both the outer and inner tires in the middle position, and thereby each of the chain pieces provided on both ends of each row chain. One end of the fastener can be placed at approximately the same length under both sides of both the outer and inner tires, and in the fastening work of the fasteners of each row chain, in two types of double chains , Each row chain is not lifted and moved, and it is possible to pull the chain to the position where the stopper is placed to make a stop.
The next task is to fasten each of the fasteners provided on the chain pieces that form both ends of the facing edge row chain, and until now, the surface edge row chain has been laterally locked to the facing edge row chain. The part of the chain and the surface edge row chain is caught on the edge or surface of the outer tire and it is difficult to pull it, and in order to solve this, with each stopper provided on the chain piece forming both ends of the surface edge row chain Separately, another fastener, that is, an intermediate fastener is provided in the middle portion, and the position of the chain piece immediately before the intermediate fastener recess and the intermediate fastener convex facing the intermediate fastener recess are A connecting gusset chain is provided by connecting the spaces with a connecting chain with a little margin, and when the intermediate fastener concave and the intermediate fastener convex are removed, the front of the horizontal locking chain and the surface edge row chain that you want to bring together By connecting the parts and being supported by the gusset chain and quickly integrating with the facing edge row chain, it is no longer caught on the edge or surface of the outer tire, and only after the back edge row chain and the lateral locking chain. All you have to do is move it closer to the facing edge row chain, and you can easily pull out one end of the stopper of the facing surface edge row chain from the side to the other side and pull it out to the hand where you can see it, so both ends of the stopper are in front of you. It can be adjusted at hand, and the fasteners can be easily attached.
The edge and surface of the surface edge row chain should not be caught, and the facing surface edge row chain should be too close to the outer and inner tires to slide down to the protruding convex part of the tire wheel according to the facing surface edge row chain. You will be freed from the hassle of pulling it up to the top of the tire.
Next, proceed to the work of fastening the fasteners provided on the chain pieces forming both ends of the back surface edge row chain, and proceed to the work of fastening the fasteners of the facing surface edge row chain to the back surface edge brought to the facing surface edge row chain. After the row chain and the lateral locking chain back are replaced, and the combined surface edge row chain and the lateral locking chain front are also replaced, and the removed intermediate fastener concave and intermediate fastener convex are stopped, then Proceed to the next work, and attach each of the fasteners provided on the chain pieces that form both ends of the back edge row chain, so you can lie down on your half body or under the car body on the back side of both the outer and inner tires. Pull both ends of the fasteners already placed under both sides to hold them together.
The next task is to join the fasteners on the chain pieces that form the ends of the surface edge row chain, and to attach both ends of the fasteners that are already placed under both sides on the front side of both the outer and inner tires. Finish the installation work by pulling them together.
Further, it is provided on the chain piece forming both ends of the surface edge row chain of the double chain of the type shown in [Fig. 2] in which one type of laterally locking chains are connected in a staggered manner at regular intervals. Only in the work of fastening each stopper, the vehicle body is moved and both the outer and inner tires are placed on one or two before the lateral locking chain and after the lateral locking chain, so that both sides on the front side of both the outer and inner tires. The fasteners that are already placed underneath are slightly misaligned, and there is no inconvenience in fastening them, so pull both ends of the fasteners together and finish the installation work.
For the installation work in the two types of double chains, it is possible to set up each one easily and quickly, so it is possible to save physical strength in cold places and snow, and to work with peace of mind and safety. You can.
In the removal work, the work method in the two types of double chains is the same, first, each fastener provided on the chain piece forming both ends of the surface edge row chain, and the intermediate fastener of another stopper. Start with the work of removing, and in the next work, remove either the fasteners provided on the chain pieces that form both ends of the back edge row chain, or the intermediate fasteners of the other fasteners that are in easy-to-remove positions. Even if both the outer and inner tires are stepping on the lateral locking chain, the facing surface edge row chain and each lateral locking chain will be loosened, so proceed to the work of the facing surface edge row chain and use the back surface edge row chain. By removing either the fastener provided on the chain piece forming both ends of the facing surface edge row chain parallel to the removed position, or another stopper, that is, the intermediate fastener, the double chain can be seen from both the outer and inner tire surfaces. Can be taken down and the removal work can be completed.
Also, if the fasteners of each row chain or the intermediate fasteners of another fastener are located in places where it is difficult to remove, each provided on the chain pieces forming both ends of the surface edge row chain. Since both the stopper and the intermediate fastener of another stopper can be easily removed, the work to remove them should be done first, and then the stopper located diagonally at the position where it is difficult to remove with the back edge row chain, or another stopper. After removing one of the intermediate fasteners of the fastener, proceed to the work of the facing edge row chain, and either the stopper of the facing edge row chain parallel to the position removed by the back edge row chain, or another By removing any of the intermediate fasteners of the fasteners, the double chain can be lowered from both the outer and inner tire surfaces, and the removal work can be completed.
Since the parking place for installation and removal work need only be at the length of the vehicle body, there is no need to choose a place even in an emergency.
By using the present invention, it is possible to add speed to the work of attaching and detaching, to preserve physical strength, and to be released from the mental pain in the severe cold.

The usage state of the present invention is as follows.
(A) In the double chain attached to the double tire, the diameter of the front edge row chain, the facing surface edge row chain, and the back surface edge row chain, which is a total of three rows, is smaller than that of the tire, and one type is , A double chain in which three rows are connected by the same horizontal locking chain at multiple locations, and the other type is a facing edge row chain and a front edge row chain and a back edge row chain on both sides. This is a type in which the lateral locking chains of the above are connected in a staggered manner at regular intervals, and in such a double chain, apart from the respective stoppers provided on the chain pieces forming both ends of the three rows of chains. Another fastener, that is, an intermediate fastener, is provided in the middle of each row chain, and in the intermediate fastener of the surface edge row chain in the intermediate fastener, the position of the chain piece immediately before the intermediate fastener recess. It is characterized in that a connecting gusset chain is provided by connecting the concave intermediate fastener and the convex intermediate fastener facing each other with a connecting chain having a length having a little margin.
(B) The installation work is the same for the two types of double chains, and another one is provided in the middle of each row chain, which is provided separately from the stoppers that form both ends of the three rows of chains. Start by placing another fastener, or intermediate fastener, in the middle of the upper surface of both the outer and inner tires, thereby placing one end of each stopper on the chain pieces that form the ends of each row chain. Each can be placed with approximately the same length under both sides of both the outer and inner tires, and in the fastening work of the fasteners of each row chain, in the two types of double chains, each row It is possible to pull the chain to the position where the stopper is placed and to hold it together without lifting and moving the chain.
(C) The next work is to fasten each of the fasteners provided on the chain pieces forming both ends of the facing surface edge row chain, and the lateral locking connected to the surface edge row chain and the facing surface edge row chain. Since the chain is moved from the middle of the edge of the outer tire to the facing edge row chain, another stopper is provided in the middle of each of the chains provided on the chain pieces forming both ends of the surface edge row chain. When a certain intermediate fastener concave and intermediate fastener convex are removed, there is a little margin between the position of the chain piece in front of this intermediate fastener concave and the intermediate fastener convex that faces this intermediate fastener concave. A connecting gusset chain is provided by connecting with a connecting chain of length. The surface edge row chain and the lateral locking chain that the connecting gusset chain approaches the facing surface edge row chain are quickly supported and integrated with the facing surface edge row chain. As a result, only the back edge row chain and the lateral locking chain can be brought closer to the facing edge row chain, and one end of the stopper of the facing surface edge row chain can be pulled out from the side surface of both the outer and inner tires to the opposite side surface. It is easy and can be pulled out closer to the hand than before, so both ends of the stopper are fastened in front of you.
(D) The next work is to fasten the fasteners provided on the chain pieces that form both ends of the back surface edge row chain, and to fasten the fasteners of the facing surface edge row chain, the facing surface edge row. The back edge row chain and the lateral locking chain that were brought to the chain were replaced, and the front edge row chain and the lateral locking chain that were integrated were returned, and the removed intermediate fastener concave and the intermediate fastener convex were stopped. Later, proceed to the next work, and the fasteners provided on the chain pieces that form both ends of the back edge row chain will be fastened, so both the outer and inner tires will be in the position of lying down on the half body or under the car body. On the back side, pull both ends of the fasteners that are already placed under both sides to hold them together.
(E) The next work is to join the fasteners provided on the chain pieces that form both ends of the surface edge row chain, and both ends of the fasteners are already positioned under both sides of the outer tire. Therefore, pull both ends of the stopper, fix them together, and finish the installation work.
(F) Further, in the chain piece forming both ends of the surface edge row chain of the double chain of the type shown in [Fig. 2] in which one type of laterally locking chains are connected in a staggered manner at regular intervals. Only by the work of fastening each of the provided fasteners, the vehicle body is moved and both the outer and inner tires are placed on one or two before the lateral locking chain and after the lateral locking chain, thereby under both sides of the outer tire. The fasteners that were positioned at are slightly misaligned, and there is no inconvenience in fastening them, so pull both ends of the fasteners together, and finish the installation work.
(G) In the removal work, the method for the two types of double chains is the same. First, each stopper provided on the chain piece forming both ends of the surface edge row chain and another stopper are intermediately fastened. We started by removing the tool, and in the next work, we removed either the fasteners on the chain pieces that form the ends of the back edge row chain, or the intermediate fasteners of the other fasteners, which are in easy-to-remove positions. Later, we proceeded to work on the facing edge row chain, with each of the fasteners on the chain pieces forming the ends of the facing edge row chain parallel to the position removed by the backside edge row chain, or with another stopper. By removing one of the intermediate fasteners, the double chain can be lowered from both the outer and inner tire surfaces, and the removal work is completed.
(H) Also, if the fasteners of each row chain or the intermediate fasteners of other fasteners are located in places where it is difficult to remove, they are provided on the chain pieces that form both ends of the surface edge row chain. Since both the fasteners and the intermediate fasteners of the other fasteners can be easily removed, the work to remove them should be done first, and then the fasteners located diagonally at the positions that are difficult to remove in the back edge row chain, or separately. After removing one of the intermediate fasteners of the fasteners, proceed to the work of the facing edge row chain, and whether it is the stopper of the facing edge row chain parallel to the position removed by the back edge row chain, or another By removing one of the intermediate fasteners of the fasteners, the double chain can be lowered from both the outer and inner tire surfaces, and the removal work is completed.

In addition, when storing after the removal work, there is a slight margin between the position of the chain piece just before the intermediate fastener recess of the surface edge row chain and the intermediate fastener convex that faces this intermediate fastener recess. By connecting with a connecting chain of a certain length and providing a connecting gusset chain, the surface edge row chains do not separate, and if the intermediate fasteners of each row chain are removed, they will be fastened and twisted. If there is, you can correct it and prepare for installation.
