Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire anti-slip device attachment device for attaching a tire anti-slip device to the outer periphery of a tire and a tire anti-slip device capable of reliably transmitting a driving force and a braking force to a road surface.

[0002]

2. Description of the Related Art As a vehicle tire anti-slip device for use in snow, etc., in addition to a generally used metal chain, an anti-slip device made of rubber or urethane elastomer has been proposed. 54-8484). Further, there is a tire slip preventing device in which rubber is stretched in a net shape in order to reduce vibration during traveling.

[0003]

In each of these anti-skid devices, the widthwise end portions thereof are hooked with a wire rope, rubber or the like and arranged on the side surface of the tire. If these wires are weakly tightened, the tire non-slip device swells due to centrifugal force during traveling, and mounting on the tire becomes uncertain. This often occurs especially when the anti-skid device is installed without the tires being jumped up, and the rope connecting the ends of the tire anti-skid device is installed eccentrically. When the rope is mounted eccentrically in this way, the rope on the front side, that is, on the outer side of the vehicle is loosened by about 40 to 50 mm during some traveling (about 100 m), and it is necessary to stop the vehicle and retighten the rope.

Further, in the case where a rubber ring is used instead of the rope, the ends of the tire anti-skid device can be pulled together by the tension of the rubber ring, but the rubber ring has a large local extension, so a small force is applied. Since it stretches due to (vehicle side force, centrifugal force, etc.), this rubber ring stretches when the tire suddenly spins or runs at high speeds, making attachment to the tire uncertain.

In consideration of the above facts, the present invention does not need to retighten the tire after traveling, and can always surely attach the tire anti-slip device to the outer circumference of the tire. It is an object to obtain a tire anti-skid device capable of transmitting power.

A flexible elongate body having a second closed loop including a portion is wrapped and used.

The flexible elongated body is made into a multi-loop state of a first closed loop not including an elastic portion and a second closed loop including an elastic portion by the multiple loop forming means,
One end side of the first closed loop and one end side of the second closed loop are connected to the multiple loop forming means. Here, since the first closed loop is supported by the support means so as to be movable only in the direction in which the loop length is shortened, when the flexible elongated body is wound around the width direction end of the tire antiskid body, The first closed loop that does not include the elastic portion, that is, the non-stretchable portion of the first closed loop that includes only the non-stretchable portion moves only in the direction in which the elastic portion applies tension to shorten the loop length. As a result, the diameter of the first closed loop is reduced, the widthwise end portion of the tire non-slip body is pulled in the direction of the rotation axis of the tire, and the tire non-slip body is mounted on the tire outer periphery without loosening.

Here, since the flexible elongated body is relatively movable in the longitudinal direction with respect to the end portion in the width direction, it is possible to urge the end portion in the width direction of the tire antiskid body in the circumferential direction. There is no problem, and the widthwise end portion of the tire non-slip body can be uniformly pulled in the rotation axis direction, whereby the tire non-slip body can be evenly attached to the tire outer periphery.

Further, even if the tire anti-slip body is loosened during the process in which the tire anti-slip body fits in with the outer circumference of the tire due to running, the first closed loop is pulled toward the second closed loop side including the elastic portion. As a result, the looseness of the tire anti-slip body is immediately eliminated. Moreover, since the first closed loop is supported by the support means so as to be movable only in the direction in which the loop length is shortened, the first closed loop does not loosen during traveling, that is, the tire antiskid body does not loosen. As a result, the tire anti-slip body can reliably transmit the driving force and the braking force to the road surface.

Further, since the flexible elongated body including the elastic portion is annularly arranged around the tire rotation axis, there is no fear that the rotational balance of the tire is disturbed. Furthermore, since the mounting device for a tire anti-skid device of the present invention uses the flexible elongated body, it can be folded in a small size and can be stored in a small space.

Further, in the tire anti-skid device according to the second aspect, first, the tire anti-slip body is arranged on the outer circumference of the tire,
Next, a flexible length having a first closed loop that does not include an elastic portion and a second closed loop that includes an elastic portion at a plurality of widthwise end portions provided in the circumferential direction of the tire antiskid body. Wrap the scale to use.

The flexible elongated body is made into a multi-loop state of a first closed loop including no elastic portion and a second closed loop including an elastic portion by the multiple loop forming means,
One end of the closed loop and one end of the second closed loop are connected to the multiple loop forming means. Here, since the first closed loop is supported by the support means so as to be movable only in the direction in which the loop length is shortened, when the flexible elongated body is wound around the width direction end of the tire antiskid body, A first closed loop that does not include an elastic part, ie
The non-stretchable part of the first closed loop consisting only of the non-stretchable part,
The elastic portion applies tension and moves only in the direction in which the loop length is shortened. As a result, the diameter of the first closed loop is reduced, the widthwise end portion of the tire non-slip body is pulled in the direction of the rotation axis of the tire, and the tire non-slip body is mounted on the tire outer periphery without loosening.

Since the flexible elongated body is movable in the longitudinal direction relative to the widthwise end portion, the widthwise end portion of the tire anti-slip body is urged in the circumferential direction. There is no such problem, and the widthwise end portion of the tire anti-slip body is evenly pulled in the rotation axis direction, and the tire anti-slip body is evenly adhered to the tire outer periphery.

Further, in the process in which the tire anti-slip body fits to the outer circumference of the tire by running, even if the tire anti-slip body is loosened, the first closed loop is pulled toward the second closed loop side including the elastic portion. As a result, the looseness of the tire anti-slip body is immediately eliminated. Moreover, since the first closed loop is supported by the support means so as to be movable only in the direction in which the loop length is shortened, the first closed loop does not loosen during traveling, that is, the tire antiskid body does not loosen. As a result, the tire anti-slip body can reliably transmit the driving force and the braking force to the road surface.

FIG. 1 shows a main portion of a mounting device 10 as a mounting device for a tire antiskid device of a tire antiskid device 12 according to a first embodiment of the present invention, and FIG.
Indicates that the tire antiskid device 12 is attached to the tire 14.

The tire anti-skid device 12 is made of a flexible thin rubber material, and has a substantially diamond-shaped main body 1 in plan view.
6, the mounting pieces 18 project at equal intervals in the width direction, and the hooks 2 as the width direction end portions are provided at the tip end portions of these mounting pieces 18.
The intermediate portion of the wire 22 as a flexible elongated body is hooked via 0. In addition, the tire slip prevention device 1
2 is not only formed of a thin rubber material, but may be formed of synthetic resin such as urethane resin as long as it is a flexible member.

Further, the mounting piece 18 is a tire slip preventing device 12.
Of the hook 2 are locked by bifurcated hooks 24 at both ends in the longitudinal direction of the hook 2 and are connected to each other at the both ends in the longitudinal direction.
4 is for hooking the hook 20 and an intermediate portion of the wire 22.

Although FIG. 2 shows only the mounting state of the tire 14 on the outside of the vehicle, the mounting state of the inside of the vehicle on the back side of the drawing is substantially the same as the front side. However, the attachment device 10 is not provided on the back side, and the width direction end portion of the tire anti-skid device 12 is simply hooked in a loop by a wire.

As shown in FIG. 1, one end of the wire 22 is attached to a main body 26 forming a part of the supporting means of the locking device 11. That is, the main body 26 has a cylindrical shape, and one end of the wire 22 is fixed to the outer periphery of the main body 26 by a bracket 28.

The main body 26 has a small-diameter portion 30 at the opposite end to which the wire 22 is attached, and a tapered portion 32 at the middle portion.

A cylindrical slider 34, which constitutes another part of the support means, is housed in the small diameter portion 30 and the tapered portion 32. This slider 34 has a through hole 36 at its axial center.
The wire 22 is inserted near the other end.

The slider 34 is provided with a plurality of through holes 38 (preferably three at equal intervals around the axis) in the radial direction from the axis, and each of the lock balls 40 constitutes another part of the supporting means. Is housed.

The slider 34 is provided with a lid 42 attached to one end of the main body 26, and a compression coil spring 44 constituting another part of the supporting means is interposed between the lid 34 and the lid 42.
4 is urged in the direction of pulling out from the small diameter portion 30. Therefore, the lock ball 40 is pressed by the inner side of the taper portion 32 in the axial direction, that is, the outer side of the wire 22 inserted through the through hole 36, and the movement of the wire 22 to the left in FIG. 1 is prevented. ing.

In this case, the inner slope of the taper portion 32 pushes the lock ball 40 toward the inner slope of the taper portion 32 when the wire 22 tries to move to the left through the through hole 36, so that the lock ball 40 is further moved toward the wire 22. Force to move to a plurality of rock balls 4
At 0, the wire 22 is firmly held and movement to the left in FIG. 1 is blocked.

From the small diameter portion 30 to the operating portion 4 of the slider 34.
6 protrudes, and if the operating portion 46 is pushed into the small diameter portion 30, a gap is created between the lock ball 40 and the inner slope of the taper portion 32, so that the firm pressing force on the wire 22 is released, and the wire 22 is released. 1 can slide to the left in FIG. 1 through the through hole 36.

A loop portion 48 is formed at the tip of the wire 22 protruding from the through hole 36, and one end of a tension coil spring 50 as an urging means is attached to the loop portion 48. The other end of the tension coil spring 50 is hooked at an appropriate position during assembly as shown in FIG. 2, and has a function of generating a force to pull the wire 22 rightward in FIG.

A bracket 52 for hooking the main body 26 on the hook 20 or the like is preferably attached to the outer periphery of the main body 26.

Next, the operation of this embodiment will be described. When the tire anti-slip device 12 is attached to the tire 14, the tire anti-slip device 12 is wrapped around the outer periphery of the tire 14 and a wire (not shown) on one side in the width direction and on the vehicle rear side, that is, the paper rear side in FIG. Hang on each other with.

Here, the wire 22 is hooked on the other side in the width direction, that is, the hook 20 and the hook 24 on the front side in FIG.

If the tip end of the tension coil spring 50 is hooked at an appropriate position such as the hook 20, the wire 22 is appropriately tensioned by the tension force of the tension coil spring 50.
Install the tire anti-skid device 12 in the tire 14 without slack.
Will be attached to the outer periphery of.

During running, some running-in (100 m
The tire 14 and the tire anti-skid device 12 are adapted to each other by centrifugal force depending on the degree), the eccentric state is corrected, and the wire 22 is changed from an elliptical shape to a circular shape. Therefore, the wire 22 is 30-
Although about 50 mm loosens excessively, the loose wire 22 passes through the through hole 36 and is pulled by the tension of the tension coil spring 50. Further, after the loosened portion is pulled, the lock ball 40 prevents the wire 22 from returning backward, so that the wire 22 does not come off from the hooks 20 and 24, and the tire antiskid device 12 is securely attached to the tire 14.
Keep attached to.

When the operating portion 46 is pushed into the main body 26 at the time of removal, the lock ball 40 disengages from the wire 22, so that the wire 22 can be easily moved in the opposite direction and the entire wire 22 is loosened, so that the hooks 20 and 24 are released. Can be removed from.

FIG. 3 shows a mounting device 10 according to a second embodiment of the present invention. In this embodiment, the locking device 11 is provided with a ratchet mechanism, a ratchet fitting 54 attached to one end of the wire 22 penetrates through the main body 56, and one end of the compression coil spring 44 is attached to the penetrating tip. . Further, the pin 58 is provided in the main body 56 with the ratchet pole 6
The middle part of 0 is pivotally supported, and one end is pressed by the compression coil spring 44 against the ratchet surface of the ratchet fitting 54. Therefore, one end of the wire 22 can move through the main body 56 toward the tension coil spring 50, but cannot move in the opposite direction due to the engagement between the ratchet pole 60 and the ratchet fitting 54.

Therefore, also in this embodiment, the same effect as the above embodiment can be obtained, and when the other end of the ratchet pawl 60 projecting from the main body 56 is pressed and rotated at the time of removal, the engagement between the ratchet pawl 60 and the ratchet metal fitting 54 can be achieved. Since the binding is released, the wire 22 can be loosened.

FIG. 4 shows a locking device 11 of the mounting device 10 according to the third embodiment of the present invention. In this embodiment, a plurality of cam cleats 68 are axially supported in the main body 64 by pins 66 at equal intervals around the axis. The cam cleat 68 has its ratchet portion pressed against the wire 22 by the biasing force of the compression coil spring 44. This pressing surface is the wire 2
It is arranged on the right side in FIG. 4 with respect to the position connecting the plurality of pins 66 so as to press the wire 22 more firmly when the wire 2 moves backward.

Further, since the arm 70 projects from the back of these cam cleats 68 and is arranged outside the main body 64, if this arm 70 is operated against the biasing force of the compression coil spring 44, the cam cleat 68 will move. The ratchet bar separates from the wire 22 and allows the wire 22 to move in the opposite direction.

It should be noted that the tire slip prevention device 12 is attached to the tire 1
In order to attach the wire to the wire 4, it is more effective if, in addition to the attachment device 10, a stretchable elongated body such as a rubber ring is hooked on the hooks 20 and 24 to easily tighten the wire 22.
In this case, instead of the hooks 20 and 24 having the shape shown in FIG. 2, as shown in FIG. 5, a hook 80 having two hook portions 80a and 80c is attached by a caulking portion 80b. Used by crimping to 18 and two hooks 80
It is convenient if the wire 22 is hooked to either a or 80c and the rubber ring or the like is hooked to the other. The same applies to the following examples.

FIG. 6 shows a mounting device 10 according to a fourth embodiment of the present invention. In this embodiment, the wire 22 and the locking device 11 have the same structure as in the first embodiment, but the first
Instead of the tension coil spring 50 of the embodiment, a long rubber band 90 as an elastic portion is used. A loop portion 92 is formed at one end of the rubber band 90, and the loop portion 92 is linked to the loop portion 48 of the wire 22 as a non-stretchable portion. The other end of the rubber band 90 is attached to the locking device 11 by a bracket 94 as a multiple loop forming means.
It is fixed through. With this configuration, the rubber band 90 has a loop shape like the wire 22. In this embodiment, the loop of only the wire 22 is the first closed loop, and the loop including the rubber band 90 is the second closed loop.
It becomes a closed loop of.

In this attachment device 10, first, the loop-shaped wire 22 is hooked on the hooks 20 and 24 shown in FIG. 7, and then the loop-shaped rubber band 90 is attached to the hooks 20 and 24. Be hung up. As a result, the wire 22 is appropriately tensioned by the pulling force of the rubber band 90, and as shown in FIG. 7, the tire anti-slip device 12 is attached to the outer periphery of the tire 14 without slack.

In this embodiment, as in the previous embodiment, the looseness of the wire 22 caused by running-in is removed by the tension of the rubber band 90, but unlike the above embodiment, the rubber band 90 is different.
The end portion of is fixed to the locking device 11 so that it is not necessary to select the end locking position. Therefore, as a result of the locking position being different depending on the amount of force applied by the person operating the rubber band 9,
There is no difference in the tension applied to 0, and the tension of the set value is always applied.

Further, the wire 2 constituting the mounting device 10
Since the rubber band 90 and the rubber band 90 are annularly arranged around the tire rotation axis, there is no fear that the rotational balance of the tire will be lost as compared with the case where the springs and the like are arranged eccentrically with respect to the tire rotation axis.

Further, in this embodiment, the rubber band 90 is not pulled linearly in the longitudinal direction but is pulled in the crossing direction of the longitudinal direction and is hooked on the hooks 20 and 24. It is easy to stop and remove. The operation force is reduced even when compared with the conventional one using three ring-shaped rubber bands.

Further, since the rubber band 90 applies the same tightening force as that of the ring-shaped rubber band, the wire 22 is constrained in a loop shape, so that the tire 14 and the tire antiskid device 12 are displaced from each other. In addition, the effect of preventing wheel slipping and rolling of the tire slip prevention device 12 is extremely large.

The locking device 11 can be hung between the hooks 20 and the like instead of being hooked on the hooks 20 and the like.

Also, the end of the rubber band 90 is fixed to the locking device 1
1 so that it can be detachably hooked, and when it becomes necessary to adjust the tension, it can be hooked on the hook 20 or the like,
The rubber band 90 may be used so as to be hooked on the locking device 11 after the rubber band 90 is rotated once. Furthermore, the end of the rubber band 90 may be set so as to be hooked on the hook 20 or the like from the beginning. In this case, the rubber band 90 does not need to make a complete round, and conversely may make one round or more.

When attaching the tire antiskid device 12, the wire 22 is pulled from the locking device 11 to the rubber band 90.
If the rubber band 90 is excessively pulled out in the direction, tension is not applied to the rubber band 90. Therefore, in order to prevent this, it is preferable to provide means for limiting the maximum length of the wire 22 pulled out from the locking device 11. As an example of a specific means for this, as shown by an imaginary line in FIG. 6, the stopper metal fitting 96 may be fixed to a predetermined position of the wire 22 by caulking or the like.

The fourth embodiment can be implemented by replacing the locking device 11 with the one shown in the second or third embodiment, but can be implemented by other various structures. .

If the hook 150 shown in FIG. 17 is used instead of the hooks 20 and 24 shown in FIG. 7, the rubber band 90 and the wire 22 are entangled with each other,
It is possible to reliably prevent the sides of the wires 22 from being pressed against each other and the slippage of the wires 22 deteriorates, which prevents the wires 22 from being narrowed down.
Such a hook 150 is also preferably used in a seventh embodiment (shown in FIGS. 15 and 16) described later.

Although the wire 22 loosens and becomes tense as the tire 14 rotates, the wire 22 is preferably made so that the rotating direction of the tire 14 and the urging direction of the wire 22 are opposite to each other. It is easy to narrow down. Therefore, in FIG. 7 (similarly in the case of FIG. 2) showing the mounted state, it is preferable that the left wheel rotates left.

Incidentally, the tire anti-slip device 12 of the present embodiment.
Is different from a conventional tire antiskid device of a type in which a pair of metal rings arranged on the tire side are connected by a plurality of chains (for example, JP-A-51-98806). Since the mounting device 10 is also formed of the flexible wire 22 and the rubber band 90, it can be folded small as a whole and can be stored in a small space. it can. Further, since the tire antiskid device 12 and the mounting device 10 can be separated from each other, they can be stored separately.

8 to 10 show a mounting device 10 according to a fifth embodiment of the present invention. In the mounting device 10 of this embodiment, a tension member 100 as a long body is formed of plastics or steel. The tension member 100 is composed of a cylindrical main body member 102 having a cutout portion extending in the axial direction, and a columnar end member 104 having a partially cutaway cross section and fixed to one end portion of the main body member 102. There is. The locking device 11 is fixed to the other end of the main body member 102.

The tension member 100 is formed in an annular shape, and the end of the end member 104 enters the inside of the main body member 102 through the housing 106 of the locking device 11. One end of a rubber band 108 serving as an elastic portion is locked to the tip of the end member 104. Rubber band 1
08 passes through the inside of the main body member 102, and further the end member 1
The other end is locked to the housing 106 through a through hole 110 formed in the housing 04.

As a result, the tension member 100 is urged by the rubber band 108 to reduce its diameter from a state in which no external force is applied. The tension member 100 at this time
2 is set to be smaller than the diameter of the circle passing through the hooks at the tips of the hooks 20 and 24 arranged annularly in FIG. 2 of the first embodiment.

A saw-toothed claw 112 is continuously formed on the inner peripheral surface of the end member 104. Further, the locking device 11 is provided with a lock lever 116 made of a spring material, one end of which is fixed to the housing 106 and the other end of which is an operating portion 114. A pawl portion 118 is formed in the middle of the lock lever 116.

The lock lever 116 is fitted between the claw portion 112 and the claw portion 112 as shown by the solid line in FIG. 9 when the operating force is not applied to the operating portion 114. Since the claw portion 112 is formed such that the inclination angles of the two sides sandwiching the apex are sharp on one side and gentle on the other side, when the end member 104 receives a load directed in the arrow A direction relative to the main body member 102, The part 112 can press the pawl part 118 to elastically deform the rock lever 116. This allows
The end member 104 can move in the direction of arrow A.
Therefore, the locking device 11 does not prevent the tension member 100 from being urged by the rubber band 108 to be reduced in diameter.

When the end member 104 receives a relative load directed in the direction opposite to the arrow A, the pawl portion 118 is moved to the claw portion 1.
The end member 104 cannot move because it blocks the movement of 12. When the operating force is applied to the operating portion 114 and the lock lever 116 is elastically deformed as shown by the chain line in FIG. 9, the end member 104 is released from the restraint by the locking device 11.

In the present embodiment constructed as described above, the operating portion 114 is pressed to bring the lock lever 116 into the state shown by the chain line in FIG. 9, and the tension member 100 is urged by the rubber band 108 in this state. The hook of the anti-slip device is expanded by increasing the diameter (reference numeral 2 in FIG. 2 of the first embodiment).
0, 24). After that, the operation unit 11
When the pressing of No. 4 is released, the pawl portion 118 and the claw portion 112 engage with each other, but regardless of this, the tension member 100 is urged by the rubber band 108 and contracted until it comes into pressure contact with the hook.

When running is started from this state and the tire and the tire anti-skid device start to fit in, the tension member 100 is urged by the rubber band 108 to be further reduced in diameter, and the diameter reduction continues until both are completely fitted. . The diameter of the tension member 100 is the operating portion 1 of the lock lever 116.
The diameter does not increase unless 14 is pressed.

In the mounting device 10 of this embodiment, the fourth
It is possible to set a large amount of diameter reduction similarly to the embodiment, and it is possible to move the inside of the main body member 102 without causing the end member 104 to generate a large frictional force with other portions. Therefore, the diameter can be reduced smoothly.

Further, in this embodiment, the tension member 10 is used.
Since 0 has a single ring shape, the appearance is simple and the appearance is improved, and there is no confusion during mounting.

In this embodiment, the tension member 10 is used.
Since 0 is made of plastic or steel, the tension member 100 itself has an elastic force, but the material of the tension member 100 may be any material having flexibility, and it is not always necessary to have elasticity. Absent.

11 to 14 show a mounting device 10 according to a sixth embodiment of the present invention. In the mounting device 10 of this embodiment, the wire 22 as a flexible elongated body is used as the locking device 1.
It can be wound up to 1.

One end of the wire 22 is locked to the housing 120 of the locking device 11. The other end of the wire 22 is locked to the outer circumference of a cylindrical reel 122 that is rotatably housed inside the housing 120.

Inside the reel 122, there is arranged a full-spring spring 124, one end of which is locked to the housing 120 and the other end of which is locked to the inner peripheral portion of the reel 122. As a result, the reel 122 is urged in the direction of arrow B in FIG.

A lock cam 128 fixed to one end of a shaft 126 penetrating the housing 120 is arranged inside the reel 122. Lock cam 128
The coil portion is wound around the shaft 126, and the other hook portion of the torsion coil spring 130 in which one hook portion is locked in the housing 120 is locked. As a result, the lock cam 128 is urged in the direction of arrow C in FIG. 13 by the torsion coil spring 130 so that the tip end thereof comes into pressure contact with the inner peripheral surface of the reel 122.

This torsion coil spring 130 is the whole dance spring 1
The biasing force of 24 is set so as not to prevent the reel 122 from winding the wire 22. Further, when the lock cam 128 receives a load in a direction in which the wire 22 is pulled out from the reel 122, the lock cam 128 strongly presses and abuts the reel 122 so that the rotation of the reel 122 can be prevented by a frictional force.

A lock release lever 132 arranged on the front surface wall 120A of the housing 120 is fixed to the other end of the shaft 126. The lock release lever 132 resists the biasing force of the torsion coil spring 130 and is indicated by the arrow D in FIG.
By rotating in the direction (counter arrow C direction), the lock cam 1
28 is separated from the inner peripheral surface of the reel 122.

In the locking device 11, a pair of mounting portions 134 projecting in a hook shape on the back wall 120B of the housing 120 are hooked on the tire anti-slip device.

In the mounting device 10 of this embodiment, a locking device 11 similar to the locking device 11 (FIG. 4) of the third embodiment is applied to the mounting device 10 (FIG. 6) of the fourth embodiment.

The locking device 11 is formed with a first through hole 102 and a second through hole 104 which are parallel to each other at one end of a body 100 made of a material such as aluminum casting and reinforced resin. The first through hole 102 has a resin-coated rope 10
6, one end of the rope 6 is inserted, and this portion of the rope 106 is formed in the loop portion 108. An intermediate portion of the rope 106 is inserted into the second through hole 104, and the other end portion thereof is the rubber band 11
It is locked to one end of 0 through a caulking metal fitting 112. The other end of the rubber band 110 is locked to the loop portion 108.

The second through hole 104 has a rectangular cross section, and the rope 106 can move in the second through hole 104 not only in the longitudinal direction but also in the longitudinal crossing direction. A pin 114 is attached to the body 100 in the second through hole 104.
A cam cleat 116 is pivotally supported by. This cam cleat 116 is urged in the direction of arrow E by a spring (not shown) to clamp the rope 106 with the inner wall of the second through hole 104, and an arm 118 formed on the cam cleat 116.
When the rope 106 is rotated in the direction opposite to the arrow E direction against the urging force, the clamped state of the rope 106 is released.

At the other end of the body 100, a pair of hooks 1
20 are formed. The hook 120 replaces the hook 24 in the fourth embodiment, and is adapted to connect both ends in the longitudinal direction of the tire antiskid device 12.

The mounting device 10 of this embodiment is a hook 120.
To the tire anti-skid device 12 and then to the tire anti-skid device 12 in the same manner as in the fourth embodiment.
The locking device 11 operates similarly to the third embodiment.

By forming the locking device 11 with a lightweight material such as reinforced resin, a good weight balance with respect to the tire rotation shaft can be achieved.

18 and 19 show a modified example of the locking device 11 of the seventh embodiment, in which the hook 120 can swing with respect to the body 100.
The locking device 11 can be miniaturized by shortening the length L under the neck shown in FIG. That is, the hook 120 is shown in FIG.
This is because it can be attached to the attachment piece 18 of the tire anti-skid device 12 by inclining as shown in FIG. In the case of this example, since the arm 118 of the cam cleat 116 projects laterally, the size can be reduced also from this point.

Further, as shown in FIG. 21, after the tire is mounted, the tire 14 is swung optimally along the shoulder portion of the tire 14, so that the tire 14 is fitted well.
