Description

  The present invention relates to an anti-slip device that is mounted on the outer surface of a tire of a vehicle, and more particularly, to an anti-slip device for a tire that is mounted on a tire to prevent slip when traveling on a slippery road such as a snowy road.

  Conventionally, this type of anti-skid tool for tires uses a chain made of metal chains as a tire when traveling on a road where tires such as snowy roads are slippery with vehicles such as large and small freight cars and passenger cars. Installed to increase grip on the road and tires. This made it difficult for the road surface and tires to slip on the snowy road. Such a metal chain has a large grip force on the road surface and the tire is difficult to slip, but it is troublesome to attach to the tire (see Patent Document 1).

  Such metal chains include a rider type (ladder type) and a turtle shell type, and also include a net-like rubber chain. However, when running with a chain attached to a tire, the chain is buried when the snow is soft, and therefore, vibration and steering vibration are less likely to occur when the vehicle is running. In addition, on a road where snow and water are frozen, a road where there is little snow, or a normal road where there is no snow, vibrations are inevitably large due to the structure of the chain, and the steering wheel shakes. For this reason, on snowy roads or frozen roads, when the vehicle is parked at the edge of the road and the chain is attached to the tires, the road ends when the snowy road or frozen road is finished. The car was stopped and the tire chain was removed. For this reason, there was a danger in attaching and detaching the chain. In addition, vibrations and steering wheel vibrations occurred when the vehicle was traveling, and high speed traveling on the highway was not possible.

  On the other hand, when a vehicle runs on a slippery road such as a snowy road, a studless tire that is not slippery on a snowy road or a frozen road without attaching a metal chain to the tire is also known. The studless tire is provided with a plurality of blocks divided in the circumferential direction of the ground contact surface (tire surface) of the tire. In addition, a cut is provided in the divided blocks, and the grip force on the snowy road or the road on which snow or water is frozen is increased by using the edge effect of these blocks. This makes it difficult for the road surface and the tire to slip on a snowy road (see Patent Document 2).

  However, the former metal chain has its structure so that it is snowed, or when the vehicle runs on a snowy road or a road where snow and water are frozen, the vehicle is stopped at the end of the road and the chain is attached to the tire. I was going. In addition, when driving on a snowy road or a frozen road was finished, the vehicle had to stop at the end of the road and the chain had to be removed from the tire. Since such a metal chain is very heavy, when a chain is attached to and detached from a tire at the end of a road, it is complicated and takes a lot of time for a weak woman or the like.

  Further, since the latter studless tire hardly generates vibrations or steering wheel, it can be mounted on the vehicle for several days, weeks or months before running on a snowy road. In this studless tire, the vehicle was lifted with a jack and the bolts fixing the tire were removed and replaced with a normal tire. Therefore, in general, once a vehicle is replaced with a studless tire, the studless tire is still mounted until the season when it is unnecessary. And if a vehicle is run for a long time with a studless tire attached, a studless part of a tire will be worn. For this reason, the studless tire has a reduced grip force on a snowy road or a road on which snow or water is frozen, and the original grip characteristic may not be exhibited in a short period of time.

  Therefore, it is desirable to develop a tire anti-slip device that can be easily attached and detached even by a weak woman and the like, and that grip force on a snowy road or a road frozen by snow or water does not decrease in a short period of time. It was rare.

  The present invention has been made to solve the problems of the related art, and can be easily attached and detached even by a weak woman or the like, and is a grip for a snowy road or a road where snow or water is frozen. An object of the present invention is to provide a tire anti-skid tool in which the force does not decrease in a short period of time.

  That is, the tire anti-skid tool of the present invention is mounted on the outer surface of a vehicle tire, and includes a grounding portion located outside the tire grounding surface, and is divided into a plurality of tires arranged in the circumferential direction of the tire. A mounting member, a first holding member for detachably holding each mounting member on the outer surface of the tire, and provided on each mounting member, are located on both sides of the tire and extend in the circumferential direction of the tire A holding unit and a binding member mounted across the holding units of all the mounting members are provided.

A projection provided and an insertion hole provided on the other side into which the projection can be inserted, wherein either one of the first and second members of the first holding member is attached to the mounting member, and the other is a tire The protrusion and the insertion hole are in positions facing each other when attached to the head.

  Still further, the tire anti-skid tool of the invention of claim 7 is characterized in that, in any one of claims 1 to 6, the grounding portion of the mounting member has a shape equivalent to the grounding surface of the studless tire. Features.

  Further, in addition to any one of claims 1 to 7, the anti-skid tool for a tire according to an eighth aspect of the present invention includes a light emitter incorporated in the binding member, and the light emitter is located outward from the binding member. It is characterized by emitting light toward

  According to the present invention, a non-slip device that is mounted on the outer surface of a tire of a vehicle, includes a grounding portion that is positioned outside the grounding surface of the tire, and a plurality of mounting members that are divided and arranged in the circumferential direction of the tire; A first holding member for detachably holding each mounting member on the outer surface of the tire; a holding portion provided on each mounting member and positioned on both outer sides of the tire and extending in the circumferential direction of the tire; Since there is a binding member mounted across the holding portions of all the mounting members, the mounting member can be held on the outer surface of the tire by the first holding member. As a result, it is possible to prevent the mounting member from falling off the tire, so that if the tire is rotated, the mounting member can be mounted at a location where the tire contacts the ground and the mounting member is not mounted. It becomes possible. Therefore, it is convenient that the mounting member can be mounted on the portion where the mounting is difficult and the tire is in contact with the ground.

  According to the invention of claim 2, in addition to the above, each mounting member is provided with the engaging portion that engages with the adjacent mounting member, so that the adjacent mounting member and the mounting member are fixed. Is possible. As a result, it is possible to prevent inconveniences such as the mounting member and the mounting member that are adjacent to each other being separated by centrifugal force when the vehicle is traveling, so that the steps between the adjacent mounting members are reduced to form a substantially flat surface. It becomes possible. Accordingly, it is possible to greatly reduce the noise during traveling of the vehicle, to reduce the shake of the steering wheel, and to greatly improve the convenience of the tire anti-skid tool. is there.

  According to a third aspect of the invention, in addition to any one of the first and second aspects, the second holding for holding the mounting members in a detachable manner at a position on the outer side surface of the tire. Since the members are provided, adjacent mounting members can be firmly coupled to each other. As a result, it is possible to maintain a stable state without lateral displacement or twisting of each mounting member due to a load applied to the tire during traveling of the vehicle. Therefore, it is possible to exhibit a good grip force between each mounting member and the road surface, and it is possible to greatly improve the safety during traveling of the vehicle.

  According to a fourth aspect of the invention, in addition to any one of the first to third aspects, the mounting member is provided with a plurality of support columns that are in contact with the ground contact surface of the tire. By changing the length dimension in the circumferential direction of the tire, it is configured so that the tip part is located in a wavy shape as a whole, and a recess is formed at the tip part of each support column, and this recess is sucker-like As a result, the long strut of each strut can be engaged in the groove formed on the ground contact surface of the tire, and the recess formed on the tip of the strut is formed on the ground contact surface and the ground contact surface of the tire. It can be adsorbed in the formed groove. Thereby, a mounting member can be reliably adsorb | sucked and fixed to the ground-contact surface of a tire. Therefore, even when the anti-skid tool is attached to the tire, it is possible to prevent inconveniences such as deterioration of the acceleration performance and braking performance of the vehicle, and to further improve the convenience of the anti-skid tool for the tire. It will be possible.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the first holding member and the second holding member include a first member having a plurality of loops and a loop. Since each of the second members has a plurality of hooks that can be detachably locked, the first member and the second member can be attached and detached. Thereby, it becomes possible to easily attach and detach the anti-skid tool to the tire. Therefore, it is possible to attach and detach the anti-skid tool for the tires very easily. For example, even a weak woman can easily attach the anti-skid tool to the tire.

  Further, according to the invention of claim 6, in addition to any of claims 1 to 5, the projection provided on either the first member or the second member of the first holding member. And an insertion hole provided on the other side through which the protrusion can be inserted, and either one of the first and second members of the first holding member is attached to the mounting member, and the other is attached to the tire In this state, since the protrusion and the insertion hole are positioned opposite to each other, for example, either one of the first and second members constituting the first holding member is made uniform between the mounting members. If it is attached and fixed to the tire, it is possible to provide a uniform gap between the mounting members mounted on the tire when the anti-skid tool is mounted on the tire. As a result, it is possible to prevent inconveniences such that end portions of adjacent mounting members overlap or gaps between adjacent mounting members vary. Therefore, since the level difference between adjacent mounting members can be minimized, noise during vehicle travel can be greatly reduced.

  Further, since the projection and the insertion hole for providing an equal gap between the respective mounting members mounted on the outer surface of the tire are provided in either the first member or the second member of the first holding member, By simply inserting the holes into the protrusions, an even gap can be provided between the mounting members mounted around the tire. Thereby, the workability | operativity which mounts between each mounting member equally can be improved very much, and the convenience of the anti-skid tool for tires can be improved extremely.

  In addition, since the mounting member can be reliably and evenly attached in the circumferential direction of the tire, the mounting member can be formed in a plane having almost no step between adjacent mounting members. Thereby, it becomes possible to improve the workability | operativity of mounting | wearing an antiskid tool very much. Accordingly, it is possible to greatly reduce noise during vehicle travel.

  Furthermore, according to the invention of claim 7, in any one of claims 1 to 6, since the grounding portion of the mounting member has a shape equivalent to the grounding surface of the studless tire, It is possible to reduce vibration and noise while the vehicle is running in a state where the grip force for the road or the road on which snow or water is frozen is maintained. As a result, for example, the steering wheel does not swing like a conventional metal chain, and the running performance of the vehicle can be extremely stabilized, so that the ride comfort of the vehicle can be greatly improved. It becomes possible. Therefore, it is possible to reliably ensure safety during vehicle travel.

  In particular, it is possible to improve the riding comfort of the tire with the tire anti-slip device attached to the tire, so for example, when going out to a ski resort in a mountainous area with snow on the road from a road without snow, a few days in advance An anti-slip device can be attached to the tire. Thereby, when going out to a ski resort etc., an anti-slip | skid tool can be mounted | worn with a tire at the time when there is time. In addition, because the ride comfort of the vehicle can be improved, if a snow forecast is given in the weather forecast, etc., a non-slip device is attached to the tire several days before the expected snowfall date, and there is no snow on the road. It is convenient to remove the anti-slip tool from Therefore, it is not necessary to perform a dangerous work such as attaching an anti-slip device to the tire at the end of the road and removing the anti-slip device from the tire at the end of the road where there is no snow. It is convenient because it is possible to ensure the safety when attaching and detaching. In addition, since it is easy to attach and detach the anti-skid tool to the tire, if the anti-skid tool is attached to the tire for several weeks before or after running on a snowy road or a road where snow and water are frozen In addition, the gripping force of the anti-skid tool can be maintained for a long time.

  According to the invention of claim 8, in addition to any one of claims 1 to 7, the light emitting body is incorporated in the binding member, and the light emitting body emits light outward from the binding member. The anti-skid tool can be seen without having to hold the flashlight by hand even in a dark place such as at night. This makes it possible to easily attach the anti-skid tool even in a dark place. Therefore, it is possible to greatly improve the mounting workability of the anti-skid tool.

  The main feature of the present invention is that a mounting member divided into a plurality of parts in the circumferential direction of the outer surface of the tire is provided in order to easily mount the anti-skid tool on the tire, and at the same time, high-speed running can be performed. For the purpose of easily attaching the anti-skid tool to the tire and enabling high-speed running, a first holding member for detachably holding the anti-skid tool and the tire is provided, and each grounding portion of the attaching member is used as a road surface. This is achieved by making it the same shape as the ground contact surface of studless tires with high grip power.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a tire 10 equipped with a tire anti-skid tool 20 according to an embodiment of the present invention. FIG. 2 is a longitudinal side view of a mounting member 22 constituting the tire anti-skid tool 20 of the present invention. 3 is a longitudinal sectional view of the mounting member 22 constituting the tire anti-skid tool 20 of the present invention.

  The tire anti-skid tool 20 is used when a tire (such as a snowy road or a frozen road) is slippery on a road (not shown) such as a large or small freight car or a passenger car on a road where the tire 10 is slippery. 10 is used by being attached to the outer surface of the tire 10, and as shown in FIG. 1, a plurality of mounting members 22 that are divided and arranged in the circumferential direction of the tire 10, and a tire for holding the tire 10 and each mounting member 22 1 holding member 40 and a binding member 60 mounted across the holding portions 28 of all the mounting members 22.

  The anti-skid tool 20 to be mounted around the tire 10 is divided into six parts and configured by a plurality of mounting members 22, and each mounting member 22 has a substantially equivalent shape. Further, the divided mounting members 22 can be connected in the circumferential direction of the tire 10. As shown in FIG. 2, the mounting member 22 is continuously provided on the outer side of the grounding surface 12 (shown in FIG. 6) of the tire 10 and on both sides of the grounding portion 24. The mounting member 22 is formed in an inverted U shape with one side open.

  The both side surface portions 26 are provided with holding portions 28 for holding the binding members 60 (shown in FIGS. 1 and 7) at the end portions of the tire 10 that extend in a predetermined direction in the center direction. The holding portion 28 is provided so as to extend in the circumferential direction of the tire 10, and the inside thereof is formed to be hollow, and when the binding member 60 is inserted into the hollow portion, the mounting member is attached by the binding member 60. 22 can be held. The binding member 60 is for securing and fixing each mounting member 22 in a state in which the plurality of mounting members 22 are mounted around the outer surface of the tire 10 with almost no gap. A rubber wire or a metal wire having a predetermined strength is used. Etc. The binding member 60 will be described in detail later.

  The grounding portion 24 (surface that contacts the ground) of the mounting member 22 is formed in a shape substantially the same as the grounding surface of the studless tire and is wider than the grounding surface 12 of the tire 10 by a predetermined size. As a result, the stopper 20 is configured not to slip even on snowy roads or frozen roads, just like studless tires. That is, the mounting member 22 is configured by a member such as a predetermined low-hardness rubber that is substantially equivalent to the studless tire, and is formed in a state where the substantially studless tire is divided into six when mounted on the tire 10. Further, the tire 10 can be urged with a predetermined urging force by the both side surface portions 26 and the holding portion 28 of the mounting member 22 in a state where the tire 10 is inserted into the opening of the mounting member 22. As a result, even when a plurality of mounting members 22 are mounted on the tire 10 and the tire 10 is rotated, the mounting member 22 can be prevented from falling off or shifting. Further, since the tire 10 can be urged by the mounting member 22 with a predetermined urging force, each mounting member 22 causes a lateral shift or twists due to a load applied to the mounting member 22 during traveling. The inconvenience can be surely prevented.

  On the inner side of the ground contact portion 24 (the surface in contact with the ground contact surface 12 of the tire 10), a large number of support columns 32 are erected at a predetermined interval. The support column 32 is configured to have a length of about 2.0 mm to 5.0 mm and a diameter of about 1.5 mm to 3.0 mm. As shown in FIG. 3, the struts 32 are formed to be long and short in the circumferential direction of the tire 10. As a result, the length of the tip end portion of each column 32 is formed in a wave shape (dotted line in FIG. 3) in the circumferential direction of the tire 10 as a whole. Since it is a well-known technique that the studless tire is difficult to slip on a snowy road or a frozen road, a detailed description thereof will be omitted.

  Moreover, the recessed part 34 is formed in the front-end | tip part of each support | pillar 32, and these recessed parts 34 are formed in the suction cup shape. That is, by forming the tip of each column 32 in a wave shape in the circumferential direction of the tire 10, a short column among the columns 32 is on the ground contact surface 12 of the tire 10, and a long column 32 is the ground contact surface 12 on the tire 10. It abuts in the groove formed. When the tire 10 rotates, the air in the recess 34 is discharged from the recess 34, and the recess 34 formed at the tip of each support column 32 passes through the recesses 34 formed in the tire 10. Can be adsorbed inside. As a result, the mounting member 22 can be securely and firmly fixed to the ground contact surface 12 of the tire 10 by suction.

  In addition, engagement portions 36 and 38 are provided on the ground contact portion 24 of the mounting member 22, and the engagement portions 36 and 38 are arranged in a state where the mounting member 22 is mounted on the outer surface of the tire 10.

  The one engaging portion 36 of the mounting member 22 can be superposed on the engaging portion 38 of the adjacent mounting member 22. As a result, the surface of the ground contact portion 24 of the tire anti-skid tool 20 is flat so that there is no step, and no gap is formed between the adjacent mounting member 22 and the mounting member 22. . That is, by providing the engaging portions 36 and 38 that engage with each other on one side and the other side of the mounting member 22, a step due to a gap between the adjacent mounting member 22 and the mounting member 22 can be prevented. Thereby, the vibration and noise during vehicle travel can be reduced by the steps of the adjacent mounting members 22.

  Further, in a state in which the mounting member 22 is mounted on the tire 10, both ends of each mounting member 22 extend in the center direction of the tire 10 with a predetermined dimension, and both ends approach each other as extending in the center direction from there. Inclined in the direction. In other words, in a state where the tire anti-skid tool 20 is mounted on the tire 10, a gap of a predetermined dimension is formed on the tire 10 center side of the adjacent mounting member 22.

The operation portion 70A of the switch 70 protrudes within the locking tool 63 by a predetermined dimension. 70 A of operation parts are covered with waterproofing members (not shown), such as rubber | gum which can operate the said operation part 70A, The operation of 70 A of operation parts and light emission of the light-emitting body 64 are carried out with snow and water with this waterproofing member. There is no problem.

  When the operation unit 70A is pressed, the light emitter 64 emits light by the power of the battery 68, and when the operation unit 70A is pressed again, the light emitter 64 is extinguished. The light emitting body 64 emits light toward the outside of the cylindrical body 66 (the binding member 60). Accordingly, the periphery of the binding member 60 is brightly illuminated, and the anti-skid tool 20 is used even in a dark place such as at night. Can be easily attached to the tire 10. The light emitter 64 is not limited to the LED, and may be an electrical resistor (light bulb) as long as the anti-skid tool 20 can be easily mounted by brightly illuminating the periphery of the binding member 60 in a dark place such as at night. In this case, since the LED consumes less power than the light bulb, the LED is used in this embodiment.

  Further, the hook 72 is connected to the wire 62 via the tightening device 74. The tightening device 74 is constituted by a worm gear composed of a screw-like internal gear 75 and an external gear 76 formed linearly in the cylinder. The external gear 76 is rotatably connected to the other side of the wire 62, and the internal gear 75 is fixed to the hook 72. In other words, the tightening device 74 rotates the external gear 76 in a predetermined direction so that the internal gear 75 moves in the back direction (wire 62 side) in the external gear 76 and rotates in the reverse direction. 75 is separated from the inner depth of the external gear 76. The worm gear is held in the state where the internal gear 75 is located in the back of the external gear 76, and the internal gear 75 that has moved in the back of the external gear 76 is held there even if the external gear 76 is released. It is well-known that it is configured not to do so.

  Next, a method of mounting the tire anti-skid tool 20 with the above configuration will be described. The internal gear 75 constituting the tightening device 74 is attached to the end of the external gear 76 (a state in which the binding member 60 is extended to the maximum). Further, it is assumed that the first member 42 constituting the first holding member 40 is attached only to the inside of the tire 10 (vehicle main body side). In addition, a normal tire having a normal width is mounted on the tire 10 of the vehicle, and the tire 10 is not jacked up and a part of the ground contact surface 12 is in contact with the ground. First, the binding member 60 is inserted into both the holding portions 28 of the mounting member 22, and the first mounting member 22 covers the outer surface of the tire 10 with the insertion hole 45 side of the mounting member 22 disposed inside the tire 10.

  At this time, the projection 44 provided in the first member 42 is inserted into the insertion hole 45 provided in the mounting member 22 of the anti-skid tool 20, and the first member 52 and the mounting member 22 fixed to the tire 10 are inserted. The fixed second member 56 is fixed. That is, each mounting member 22 is positioned by the protrusion 44 provided on the tire 10, and the tire 10 and the mounting member 22 are held by the first holding member 40. As a result, the mounting member 22 is held at a predetermined position of the tire 10 (FIG. 8). It is to be noted that the workability of mounting the mounting member 22 is improved when the engaging portion 36 provided on one side of the mounting member 22 is superposed on the engaging portion 38 provided on the other side. The mounting is started from a position substantially in contact with the ground.

  The binding member 60 inserted into the holding portion 28 of the first mounting member 22 is inserted into both the holding portions 28 of the second mounting member 22, and the insertion hole 45 side of the mounting member 22 is connected to the tire 10. The second mounting member 22 is placed on the outer surface of the tire 10 in a state of being disposed inside. At this time, the engaging portion 36 of the second mounting member 22 is superposed on the engaging portion 38 provided on the first mounting member 22 mounted on the tire 10.

  Then, the projection 44 provided on the first member 42 of the tire 10 is inserted into the insertion hole 45 provided on the second mounting member 22, and the first member 42 and the mounting member 22 fixed to the tire 10. The second member 46 fixed to is held. The second member 56 provided on the first mounting member 22 and the first member 52 provided on the second mounting member 22 are held. That is, also in this case, the second mounting member 22 is positioned by the protrusion 44 provided on the tire 10, and the tire 10 and the second mounting member 22 are held by the first holding member 40.

Is done. This is repeated, and the mounting member 22 is mounted at five portions where the tire 10 is not in contact with the ground. Next, the vehicle is moved a little to rotate the tire 10 until the location where the mounting member 22 is not mounted is positioned above. At this time, since the mounting member 22 is held on the tire by the first holding member 40, even when the tire 10 is rotated, the mounting member 22 can be prevented from being dropped or displaced.

  Finally, the sixth mounting member 22 is mounted on the tire 10 like the mounting member 22 described above. At this time, the engaging portions 38 of the sixth mounting member 22 are inserted between the engaging portions 36 of the fifth mounting member 22 and the ground contact surface 12 of the tire 10, and all the mounting members 22 are inserted. The binding member 60 is inserted between the holding portions 28. Then, the hooking tool 72 is hooked on the locking tool 63 provided at the end of the binding member 60 inserted through the holding portion 28 of each mounting member 22. Next, the external gear 76 of the tightening device 74 is rotated in a predetermined direction, and each mounting member 22 is firmly fixed by the binding member 60. The tire anti-skid tool is attached to all four wheels of the vehicle. Each mounting member 22 is firmly fixed by a binding member 60 provided inside and outside the mounting member 22.

  As described above, the tire anti-skid tool 20 includes a plurality of mounting members 22 that are divided and arranged in the circumferential direction of the tire 10, and a first holding member that detachably holds the mounting members 22 on the outer surface of the tire 10. 40 and a holding portion 28 provided on each mounting member 22 and positioned on the outer sides of both sides of the tire 10 and extending in the circumferential direction of the tire 10. The anti-skid tool 20 (the plurality of mounting members 22) can be held on the tire 10.

  Then, if the tire 10 is rotated about a half turn and the ground contact surface 12 of the tire 10 on which the mounting member 22 is not mounted is positioned upward, the mounting member 22 is mounted without the mounting member 22 falling off the tire 10. The mounting member 22 can be mounted at a location that is not. Thereby, since the mounting member 22 can be easily mounted on the outer surface of the tire 10 that has been difficult to mount, for example, even a weak woman can easily mount the tire anti-skid tool 20 to the tire 10. .

  In addition, since each mounting member 22 is provided with the engaging portion 36 that engages with the adjacent mounting member 22, the step between the adjacent mounting members 22 can be reduced. Specifically, since the step between adjacent mounting members 22 can be reduced and formed in a substantially flat surface, it is possible to greatly reduce noise during vehicle travel due to the step between the mounting members 22.

  Moreover, since the 2nd holding member 50 for hold | maintaining each mounting member 22 so that attachment or detachment is mutually possible is provided in the position used as the side surface of the tire 10, each mounting member 22 can be couple | bonded firmly. . As a result, it is possible to maintain a stable state in which the mounting members 22 are not displaced or twisted by a load applied to the mounting members 22 during traveling. Accordingly, it is possible to exhibit a good grip force between each mounting member 22 and the road surface, and it is possible to greatly improve the safety during vehicle travel.

  Further, the mounting member 22 is provided with a plurality of support columns 32 that are in contact with the ground contact surface 12 of the tire 10, and the lengths of the support columns 32 are set in the circumferential direction of the tire 10 so that the tip ends of the support columns 32 are entirely disposed. And a recess 34 is formed at the tip of each strut 32, and the recess 34 has a suction cup shape. It can be engaged in the groove. Further, the recess 34 formed at the tip of the column 32 can be adsorbed in the tread surface of the tire 10 and the groove of the tread. Thereby, the mounting member 22 can be reliably sucked and fixed to the ground contact surface 12 including the inside of the groove of the tire 10. Therefore, when the mounting member 22 is mounted on the tire 10, it is possible to reliably prevent inconveniences such as deterioration of the acceleration performance and braking performance of the vehicle.

  The first holding member 40 and the second holding member 50 include a first member 42 having a plurality of loops, and a second member having a plurality of hooks that can be detachably locked to the first member 42. Therefore, each mounting member 22 can be easily attached and detached. Thereby, the attachment / detachment work of the anti-skid tool 20 for the tire 10 can be performed very easily, which is convenient.

  Further, a projection 44 provided on one of the first member 42 and the second member 46 of the first holding member 40 and an insertion hole 45 into which the projection 44 can be inserted are provided on the other. Then, the projection 44 and the insertion hole 45 in a state where one of the first member 42 and the second member 46 of the first holding member 40 is attached to the mounting member 22 and the other is attached to the tire 10. Are positioned opposite to each other. For example, one of the first member 42 and the second member 46 constituting the first holding member 40 is placed on the tire 10 so that the distance between the mounting members 22 is equal. If attached, the end portions of the adjacent mounting members 22 overlap each other only by inserting the projection 44 provided on one holding member into the insertion hole 45 of the other holding member, or between adjacent mounting members 22 It is possible to prevent such inconveniences that the gaps in the gaps vary. As a result, when the mounting member 22 is mounted on the tire 10, the step of the adjacent mounting member 22 can be reduced so that it can be formed in a substantially flat surface, so that the mounting workability of the anti-skid tool 20 is greatly improved. It becomes possible. In addition, since the steps of each mounting member 22 mounted on the tire 10 can be reduced and formed in a substantially flat surface, noise during vehicle travel can be greatly reduced.

  In addition, since the ground contact portion 24 of the mounting member 22 is formed in a shape substantially equivalent to the ground contact surface of the studless tire, the snow road or snow and water is frozen in a state where vibration and noise during vehicle running are reduced. It becomes possible to maintain the grip force against the road. As a result, the steering wheel does not swing like a conventional metal chain or rubber chain, and the running performance of the vehicle can be extremely stabilized. Therefore, it is possible to greatly improve the riding comfort of the vehicle, so that it is possible to reliably ensure safety when the vehicle is traveling.

  In particular, since noise and safety during vehicle traveling are ensured and the ride comfort is improved, the tire 10 has the anti-skid tool 20 attached to the tire 10 and the mountainous area where there is snow on the road. When going out to a ski resort or the like, the anti-skid tool 20 can be attached to the tire 10 for several days in advance. Thereby, when going out to a ski resort etc., when there is room in mounting | wearing of the anti-skid tool 20, the anti-skid tool 20 can be mounted | worn with the tire 10. FIG.

  Further, since the riding comfort of the vehicle is improved with the tire anti-skid tool 20 attached to the tire 10, if a snowfall forecast is given by a weather forecast or the like, the tire 10 is several days before the expected snowfall date. It is convenient that the anti-skid tool 20 is mounted on the road, and the anti-skid tool 20 can be removed after the road has no snow. Therefore, it is not necessary to perform a dangerous work such as attaching the anti-skid tool 20 to the tire 10 at the end of the road and removing the anti-skid tool 20 from the tire 10 at the end of the road where there is no snow. In addition, significant safety can be ensured in the attaching / detaching work of the anti-skid tool 20.

  In addition, since the light emitter 64 is built in the binding member 60 and the light emitter 64 emits light outward from the binding member 60, the flashlight can be held by hand even in a dark place such as at night. The anti-skid tool 20 can be visually recognized. This makes it possible to attach the anti-skid tool 20 very easily even in a dark place. Therefore, it is possible to greatly improve the mounting workability of the anti-skid tool 20, which is convenient.

  In the embodiment, the tire 10 to which the tire anti-skid tool 20 is attached is described as a normal tire having a normal width. However, the tire 10 to which the anti-skid tool 20 is attached is attached to a tire having a wider width than a normal tire having a normal width.

Although the side is cut out in a stepped shape with a predetermined dimension, both the engaging portions 36 and 38 are not cut out in a stepped shape, and both end portions of each mounting member 22 may be obliquely overlapped. In this case, one side of the mounting member 22 is cut obliquely so as to be separated from the center side of the tire 10 in the circumferential direction, and the other side is closer to the center side as it goes from the outside of the tire 10 in the circumferential direction. In this way, when the engaging portions 36 and 38 are overlapped with each other, the steps between the mounting members 22 may be reduced so as to be substantially flat. Also in this case, since the space between the mounting members 22 can be formed in a substantially flat surface, it is convenient because the noise during vehicle travel can be greatly reduced.

  Further, the anti-skid tool 20 is constituted by the mounting member 22 divided into six parts. However, the anti-skid tool 20 is not limited to six parts, but is divided into three parts, four parts, five parts or more than six parts 7, 8, 9, 10 There is no problem even if it is divided. Also in this case, the same effect as in the case of 6 divisions can be obtained, and the convenience of the tire anti-skid tool 20 can be improved, which is convenient.

  Further, the first member 42 constituting the first holding member 40 is attached at a predetermined position after the tire 10 is removed from the vehicle, but the first holding member 40 is attached to the vehicle without removing the tire 10 from the vehicle. The first member 42 can also be attached while visually recognizing the inside of the tire 10. In this case, the first member 42 can be attached without removing the tire 10, and the tire anti-skid tool 20 can be attached to the tire 10 in a short time, which is convenient.

  In addition, when the anti-skid tool 20 is attached to the tire 10, the first member 42 is attached and fixed to the tire 10 after marking the tire 10 where the first member 42 is fixed in advance. The first member 42 can be fixed by preparing a guide tool in the tire 10 so that the mounting members 22 have substantially the same gap, and attaching the tire anti-skid tool 20 using the guide tool as a guide. The members 22 can be attached so as to have substantially the same gap. This is convenient because the first member 42 can be easily and reliably attached to the tire 10.

  Further, although the mounting member 22 is held on the tire 10 using the first holding member, a band (not shown) that can be inserted into a hole (not shown) provided in advance in the rim 14 is provided, and the first and second bands are provided at both ends of the band. A holding member equivalent to the first member 42 may be provided, and the mounting member 22 may be held on the outer surface of the tire 10 by this holding member. In this case, the mounting member 22 does not fall off the tire 10 even when the tire 10 is rotated, and the mounting member 22 can be mounted at a location where the mounting member 22 is not mounted.

  Moreover, although the shape and dimension of the anti-skid tool 20 for tire were described in the Example, it cannot be overemphasized that a shape and a dimension may be changed in the range which does not deviate from the summary of the anti-skid tool 20 for tire.
