Description

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 for a vehicle which is mounted on wheels to prevent the tire from slipping when traveling on a snowy road or the like.

[0002]

2. Description of the Related Art Conventionally, as an anti-slip device for a vehicle, an integrated type and a split type are known from the form thereof. Although those made of rubber and those made of synthetic resin are known, fixing to the tire is generally performed at the rear edge (in the axle direction) and the front edge (the axle direction), respectively. is there.

On the other hand, Japanese Patent Application Laid-Open No. 8-142618 discloses that a tire chain is divided into a plurality of units along the direction of wheel rotation, and a rear edge and a front edge of each are formed on a wheel. An arrangement configured to connect through a hole is disclosed. By employing such a tire chain, it is not necessary to connect the tire chain on the rear side of the wheel, and it is possible to facilitate the chain mounting operation.

[0004]

However, the tire chain described in the above publication has the following problems.

That is, in each of the divided units constituting the tire chain, one end of a belt mechanism composed of a plurality of rigid members is connected to the inner edge of the chain body covering the tire, and the other end of the belt mechanism is connected to the chain. Since the front side edge of the main body is connected with the buckle mechanism, the structure is complicated, and it is difficult to insert the belt mechanism into the hole of the wheel.

The present invention has been made in view of such circumstances, and has as its object to provide a tire anti-slip device for a vehicle that can be easily mounted on wheels with a simple configuration. Things.

[0007]

According to the present invention, a belt insertion hole is formed in a non-slip body made of a plate-shaped member, and a belt inserted through the hole is inserted into inner and outer through holes of a wheel so that both ends of the belt are inserted. The above-mentioned object is achieved by adopting a configuration for linking.

That is, the vehicle tire slip prevention device according to the present invention comprises a plate-like member having both surfaces set as a ground contact surface and a tire contact surface. A non-slip body having a belt insertion hole formed between the contact surface and a belt inserted into the belt insertion hole of the anti-slip body, and both ends of the belt are adjusted to a predetermined belt length and connected. And an adjusting connector, wherein the tire contact surface of the non-slip body is brought into contact with the outer peripheral surface of the tire, and both ends of the belt are adjusted and connected in a state where the belt is inserted into the inner and outer through holes of the wheel. The anti-slip body is configured to be mounted on a tire by adjusting and connecting with a tool.

The specific configuration such as the shape and material of the "anti-slip body" and the "belt" is not particularly limited, but the material of the "anti-slip body" is selected from the viewpoint of its anti-slip function. For example, it is preferable to use a synthetic resin, rubber, or the like. As for the “belt”, for example, a material using nylon-based cloth or the like is preferable from the viewpoint of securing the tensile strength.

The specific configuration of the "adjustment coupler" such as the shape and material is not particularly limited.
For example, a general-purpose adjustment connector used for a shoulder belt of a bag, a belt for slacks, or the like can be employed.

The above-mentioned "inner and outer through-holes" mean holes that penetrate the wheel in the axle direction, and the size, shape, and the like are particularly limited as long as the belt can be inserted. is not.

[0012]

As described above, in the anti-skid device for a vehicle according to the present invention, a belt is inserted through a belt insertion hole of a non-slip body made of a plate-shaped member, and the tire of the anti-slip body is used. With the contact surface in contact with the outer peripheral surface of the tire, and with the belt inserted through the inner and outer through holes of the wheel, both ends are adjusted and connected with the adjusting connector so that the tire can be mounted on the non-slip body. With the configuration, the following operation and effect can be obtained.

That is, in the case of a vehicle provided with wheels having inner and outer through holes through which a belt can be inserted, the vehicle is stopped when it is necessary to attach a tire anti-slip device such as when entering a snowy road. By taking out the above-mentioned tire anti-slip device and inserting the belt through the inner and outer through holes of the wheel and adjusting and connecting with the adjusting connecting tool, it is a very simple work,
The tire anti-slip device can be mounted. At this time, the belt may be inserted through the inner and outer through holes located at a rotation angle position where it can be easily inserted, and there is no need to jack up wheels or move the vehicle as in the related art.

In this case, even if only one of the above-mentioned tire anti-skid devices is mounted, the anti-slip body grips the road surface each time the wheel makes one rotation, so that the road surface grip can be used to rotate the wheel without idling. The force can be transmitted to the road surface, so that the vehicle can run smoothly even on a snowy road or the like.

However, as in the case of traveling on a steep uphill road,
Under a situation in which a large force for retreating the vehicle is applied even during one rotation of the wheel, it may be impossible to travel only with one tire slip prevention device. In such a case, the vehicle can run smoothly by mounting the tire anti-slip device at a plurality of locations on the wheel. In this case, the mounting location is 3,
With about four locations, mounting can be performed without the need for jack-up or the like.

As described above, according to the present invention, the tire anti-slip device can be easily mounted on wheels. In addition, since the tire anti-skid device can be configured only with the anti-slip body, the belt, and the adjusting connector, the configuration can be made extremely simple and inexpensive. In addition, when not in use, the belt can be folded down to make it very compact, and a large storage space is not required, so it is easy to always keep it in the trunk or the like and appropriately deal with unexpected snowfall etc. It becomes possible.

The tire anti-slip device according to the present invention may be directly mounted on wheels.
It may be mounted on a normal tire chain mounted on wheels. By doing so, a very large road surface grip force can be obtained.

Even if the outer shape of the "anti-slip body" is set to a simple rectangular parallelepiped shape or the like, the anti-slip function itself is exhibited by the fact that the anti-slip body protrudes from the outer peripheral surface of the tire. , As described in claim 2,
If the ground contact surface is formed in an uneven shape, the tire slip prevention function can be further enhanced. Furthermore, if the tire contact surface of the non-slip body is also formed in an uneven shape, the effect of preventing the slip-preventive body from being displaced with respect to the tire can be enhanced.

In the above construction, if the belt is provided with a wraparound preventing portion to prevent the adjustment coupler from wrapping around the outer peripheral surface of the tire, the vehicle can be displaced. It is possible to prevent a situation in which the adjustment connector is shifted during running and goes around to the outer peripheral surface to be stepped on by the tire and damaged.

The belt insertion hole and the belt may be single, but a plurality of them may be provided.
At this time, as described in claim 4, a pair of belt insertion holes are formed near both ends of the non-slip body in the wheel rotation direction, and the belt is inserted into each of the pair, so that the non-slip body is adapted to the tire. The mounting posture can be further stabilized.

[0021]

Embodiments of the present invention will be described below with reference to the drawings.

First, a first embodiment of the present invention will be described.

FIG. 1 is a longitudinal sectional view showing a tire anti-slip device 10 of a vehicle according to the present embodiment mounted on a wheel 2, and FIGS. 2 and 3 are views taken along arrows II and III. is there.

As shown in these figures, the wheel 2 to which the tire anti-slip device 10 according to the embodiment is mounted has a plurality of inner and outer through holes 6a formed in the circumferential direction as the wheel 6 for supporting the tire 4. Aluminum wheels are used.

The tire anti-slip device 10 is made of a rubber (for example, neoprene) plate-like member having both surfaces set as a ground contact surface 12a and a tire contact surface 12b.
Non-slip body 12 having a belt insertion hole 12c formed between ground contact surface 12a and tire contact surface 12b, and belt 1 inserted through belt insertion hole 12c of anti-slip body 12
4 and an adjustment connector 16 for adjusting the both ends 14a, 14b of the belt 14 to a predetermined belt length for connection.

In the tire anti-skid device 10, the tire contact surface 12b of the anti-slip body 12 is brought into contact with the outer peripheral surface 4a of the tire 4, and the belt 14 is inserted through the inner and outer through holes 6a of the wheel 6. The both ends are adjusted and connected by the adjustment connecting tool 16 so that the non-slip body 12 is mounted on the tire.

As shown in FIG. 4, the non-slip body 12 has a contact surface 12a and a tire contact surface 12b.
Are each formed in an uneven shape. The unevenness of the grounding surface 12a is formed by a plurality of ribs 12a1 having a rectangular cross section and extending in the same direction as the belt insertion hole 12c.
The central portion of 2a is in a state where the ribs have been cut. Thus, the tire slip prevention function in the wheel rotation direction is sufficiently enhanced, and the tire slip prevention function in the axle direction is sufficiently ensured. On the other hand, tire contact surface 1
The unevenness 2b has a fine zigzag cross section and extends in the same direction as the belt insertion hole 12c. Since the non-slip body 12 is made of rubber, slip between the anti-slip body 12 and the tire 4 is unlikely to occur. To increase. Since the non-slip body 12 has the same cross-sectional shape except for its central portion, the extruded product is subjected to partial post-processing (the ground contact surface 1).
By cutting the central portion of the rib 12a1 of 2a), it can be manufactured at low cost.

As shown in FIG. 5, the adjusting connecting member 16 comprises a male connecting member 16A and a female connecting member 16B.
By inserting a pair of engagement pieces 16Aa of the male side connection tool 16A into the engagement holes 16Ba of the female side connection tool 16B to a predetermined position, the two connection tools 16A, 16B are engaged, and the both engagement pieces 16Aa are engaged. With both connectors 1 pressed from both sides
The engagement is released by separating 6A and 16B. A belt engaging bar 16Ab and a belt retaining bar 16Ac are formed on the male connecting member 16A, and a belt engaging bar 16A is formed on the female connecting member 16B.
Bb is formed.

The belt 14 is made of a nylon resin. One end 14a of the belt 14 is inserted through the belt locking bar 16Bb of the female connector 16B.
In the vicinity of a, it is folded three times and sewn, thereby forming the wraparound preventing portion 14c. Since the wraparound portion 14c has a thickness three times the thickness of the belt 14, the vertical width of the belt insertion hole 12c of the anti-slip body 12 (1.5 to 2 times the thickness of the belt 14).
The thickness is much larger than that. For this reason, even if the adjusting connector 16 gradually shifts due to repetition of elastic deformation of the tire 4 during running of the vehicle and tries to sneak toward the outer peripheral surface 4 a of the tire 4, the sneaking prevention unit is provided before that. Since the end of 14c abuts against the end face of the non-slip body 12 to prevent the adjustment connector 16 from wrapping around, it is possible to prevent the adjustment connector 16 from being broken by the tire 4 and being damaged. Is done. On the other hand, the other end 14b of the belt 14 is double-folded and sewn. On the other end 14b side, the belt 14 is locked by the belt locking bar 16Ab of the male-side connecting tool 16A and folded back while being pressed against the edge of the belt retaining bar 16Ac. Has become.

When the tire anti-slip device 10 is mounted on the wheel 2, the belt 14 is slightly extended (ie, the belt folding length at the other end 14 b side is shortened). Male connector 1 of fixture 16
6A and the female connector 16B are connected, and the other end 14b of the belt 14 is pulled to tighten the belt 14 so that the belt 14 is not loosened. Since the belt 14 passes through the belt retaining bar 16Ac of the male-side connecting member 16A, the belt 14 once tightened does not loosen.

Once the length of the belt 14 has been adjusted in this way, when the tire anti-slip device 10 is released or mounted next time, the male coupling 16A is used.
It is only necessary to perform the work of disengaging or re-engaging the female connector 16B with the female connector 16B, thereby improving the workability.

When it is necessary to prevent the tires from slipping while the vehicle is running, such as when entering a snowy road, the vehicle is stopped and the tire slip preventing device 10 is taken out.
The tire 2 is brought into contact with the outer peripheral surface 4a of the tire 4, the belt 14 is inserted into the inner and outer through holes 6a of the wheel 6, and both ends thereof are adjusted and connected by the adjusting connector 16. The device 10 can be mounted. At this time, the belt 14 may be inserted through the inner / outer through-hole 6a at a rotation angle position where it can be easily inserted, and there is no need to jack up wheels or move the vehicle as in the related art.

In this case, the tire anti-slip device 1
Even if only 0 is mounted, the slip prevention body 12 grips the road surface each time the wheel 2 makes one rotation, so that the road surface grip can transmit the rotational driving force to the road surface without causing the wheel 2 to idle. Therefore, the vehicle can run smoothly even on a snowy road or the like.

However, as in the case of driving on a steep uphill road,
In a situation in which a large force is applied to move the vehicle backward even while the wheel 2 makes one rotation, as shown in FIG. Can run smoothly.
In this case, if the number of mounting locations is about four as shown in the figure, mounting can be performed without requiring jack-up or the like.

As described above, according to the present embodiment, the tire anti-slip device 10 can be easily mounted on wheels.
In addition, since the tire anti-slip device 10 includes only the anti-slip body 12, the belt 14, and the adjustment coupler 16, the configuration can be made extremely simple and inexpensive. Also, when not in use, the belt 14 can be folded down to make it very compact, and a large storage space is not required, so it is easy to always keep it in the trunk or the like and appropriately cope with unexpected snowfall. Becomes possible.

In this embodiment, the wheel 6
Is an aluminum wheel, but a steel wheel or the like may be used as long as the inner and outer through holes 6a through which the belt 14 can be inserted are formed. However, since a brake mechanism is generally provided near the rear side of the wheel, the inner and outer through holes 6a need to be formed at positions where the belt 14 does not interfere with a brake disk or the like.

In this embodiment, the anti-slip body 12
In the above description, the belt insertion hole 12c was formed over the entire length of the belt insertion hole.
4 to prevent the slipper main body 12 and the belt 14 from being inserted.
The belt insertion hole 12c may be formed only in a part of the position as long as the positional relationship with the position can be maintained constant.

Next, a second embodiment of the present invention will be described.

FIG. 7 is a longitudinal sectional view showing the tire anti-slip device 20 of the vehicle according to the present embodiment mounted on the wheel 2, and FIGS. 8 and 9 are views taken along arrows VIII and IX. is there.

As shown in these figures, the tire anti-slip device 20 according to the embodiment also comprises a non-slip body 22, a belt 24 and an adjusting connector 26, but the following configuration is different from that of the first embodiment. ing.

That is, the anti-slip body 22 is a rubber press-formed product, and a pair of belt insertion holes 22c is formed near both ends in the wheel rotation direction. Each of the belts 24 is inserted. The configuration of each of the belts 24 is the same as that of the belt 14 of the first embodiment.

Further, the contact surface 22 of the non-slip body 22
The concavo-convex shape a is formed by a combination of a plurality of ribs 22a1 extending in the same direction as the belt insertion hole 22 and a plurality of ribs 22a2 extending in a direction orthogonal to the belt insertion hole 22 (ie, the wheel rotation direction). The stop function has been enhanced sufficiently.

The adjusting connector 26 comprises a rectangular ring 28 and a fastener 30.

One end 2 of the belt 24 is attached to the rectangular ring 28.
The portion near 4a and the other end 24b is inserted and locked. The belt 24 has one end 24
In the vicinity of a, it is folded three times and sewn, thereby forming the wraparound preventing portion 24c. The other end 24b of the belt 24 is double-folded and sewn, and is sandwiched by the fastener 30 in the vicinity thereof, thereby preventing the belt 24 from being loosened.

When the tire slip prevention device 20 is mounted on the wheel 2, the belt 24 is wound around the tire 4 and
8, the belt 24 is tightened by pulling the other end 24b of the belt 24. In this state, the belt 24 is fixed by the fastener 30. As shown in FIG. 8, the fastener 30 is configured such that the main body 30 a is attached to the belt 14 and the tire 4.
, And the flaps 30b and 30c are sequentially rotated in the direction of the arrow shown in the figure to fit the flaps 30b and 30c, thereby sandwiching the belt 24.

As described above, also in the present embodiment, similarly to the first embodiment, mounting of the tire anti-skid device 20 on wheels can be easily performed, and a very simple and inexpensive configuration can be achieved. The storage space in use can be reduced in size.

Further, in the present embodiment, the belt 24 is inserted into each of the pair of belt insertion holes 22c formed near both ends of the non-slip body 22 in the wheel rotation direction. 4 can be further stabilized than in the first embodiment.

When the tire slip preventing device 20 is mounted on the wheel 2, the pair of belts 24 are inserted into the inner and outer through holes 6a of the wheel 6. At this time, both belts 24 are connected to the same inner and outer through holes 6a. However, it is preferable to insert the anti-slip main body 22 into the tire 4 more stably by inserting the anti-slip main body 22 into different inner and outer through holes 6a (for example, adjacent inner and outer through holes 6a as shown in FIG. 8).

FIG. 10 is a view showing a state in which the above-mentioned tire anti-slip device 20 is mounted at four positions of the wheel 2. The operation and effect of mounting the tire anti-slip device 20 at a plurality of locations of the wheel 2 in this manner are the same as those of the first embodiment,
Also, as shown in the figure, if the number of mounting locations is about four, mounting can be performed without the need for jack-up or the like.
