Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tire anti-slip device that can be easily attached and detached from the outer surface of an automobile wheel.

[Conventional technology]

Conventionally, as this type of tire slip prevention device, for example, Japanese Patent Application Laid-Open No. 62-155109 and Japanese Patent Application Laid-Open No. 62-1
A technique disclosed in Japanese Patent No. 55110 is known. The device disclosed in the publication includes a center member consisting of three bearing members rotatably supported around a shaft, and a center member that is rotatably supported longitudinally by first and second bearing members of the center member. A telescopic member made of an elastic member has one end fixed to the third bearing member of the center member, and a snow chain connected to one end of each arm.

When installing this tire anti-slip device, the snow chain is placed on the tire tread surface at the top of the outer side of the automobile wheel, and after the snow chain is pulled to the tire tread surface at the contact point, the elastic member is extended. Attach a hook to its free end and hook it to a ventilation hole provided in the disc part of the wheel. When the car is started from this mounting position and the wheels are rotated, the snow chains follow the movement of the wheels and are pulled into a predetermined position, covering the entire circumference of the tire tread surface. The anti-slip device is held in the operative position by being supported by arms extending radially outward from a center member attached to the wheel.

[Problem to be solved by the invention]

The above tire slip prevention device has a structure in which the elastic member fixed to the center member is attached to the ventilation hole provided in the disc part of the automobile wheel. It cannot perform its original function unless it is mounted on a wheel with the required number of holes at predetermined positions.

However, the location and number of ventilation holes in a wheel vary depending on the type, model, and design of the wheel, and commercially available wheels have holes that are required to accommodate the elastic member of the tire anti-slip device with the above structure. Few wheels are equipped with a certain number of ventilation holes, and many light alloy wheels in particular are designed with an emphasis on fashion. However, most of these devices are not compatible with the above-mentioned devices, and there is a restriction that only a few types of wheels can be properly fitted with this tire anti-slip device.

Also, if the position and number of ventilation holes are not appropriate,
When using a tire slip prevention device that uses force, the elastic member cannot be securely attached to the ventilation hole, so the elastic member may become unlatched while the tire is running, causing tire slippage. There is a problem in that the locking device cannot stably perform its original function.

This invention aims to solve the above problems.
This type of tire slip prevention device can be accurately mounted on all wheels, regardless of the type, model, design, etc. of the wheel, whether or not there are ventilation holes, and the location and number of ventilation holes.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, the anti-slip device is composed of an anti-slip device main body and an anti-slip device anchoring body.

The anti-slip device body includes a tread member that is placed on the tread surface of the tire and covers the entire circumference of the tread surface, and one lengthwise end of the tread member that is connected to one side edge of the tread member at intervals, and is attached to the outer surface of the wheel. a plurality of arm members arranged on the sides of the wheel and narrowing radially toward the axis of the wheel;
An annular main member that is disposed close to and substantially coaxial with the axis of the wheel and loosely connects the other ends of the arm members in the longitudinal direction while maintaining a distance from each other, and connects approximately the center portion of the adjacent arm members. Consisting of a pair of links, one end of each link is attached rotatably around the direction perpendicular to the length direction of the arm member via a hinge that is rotatable around the length direction of each arm member, and the other An opening/closing member whose end is bendably attached to one side toward the tread member via a common pin, and a band-shaped member with one lengthwise end fixed to each opening/closing member and a hook attached to the other end. and an elastic member.

The non-slip device attachment body includes a fixing member fixed to the wheel and having a shaft coaxially with the wheel, and a hook of each band-shaped elastic member of the non-slip device main body, which is rotatably attached to the shaft of the fixing member. and a rotating member provided with an engaging portion that engages the.

[Effect]

The anti-slip device anchoring body of the tire anti-slip device of this invention is attached in advance to the wheel of the automobile to which the device is to be installed.

When attaching the anti-slip device to a tire, place the tread member so as to surround the tire tread surface from the outer side of the wheel, and then slide the hook of the band-shaped elastic member fixed to the opening/closing member. Temporary attachment is achieved by engaging with a retaining portion provided on the rotating member of the retaining device retaining body. When the car is started in this state and the wheels are rotated, the tread member is pulled into a position covering the entire circumference of the tread surface of the tire, resulting in a state in which it is fully installed.

When removing the anti-slip device from the tire, detach the hook of the band-shaped elastic member that is attached to the engagement part of the anti-slip device attachment body, and remove the tread from the tire, leaving only the ground-contacting part of the tread member intact. If you pull it out from the tread surface towards you and start the car in this state and rotate the wheel, it will be completely removed from the wheel.

When storing the anti-slip device body removed from the tire in the trunk of a car, bend the link of the opening/closing member toward the tread member using the pin as a fulcrum, and fold the arm member into an umbrella shape relative to the main member. At the same time, the tread member is compressed to have a compact shape.

They are arranged in a radially narrowed manner at intervals.

A spacer 15a is attached to the main member 15 to maintain the locking portions 14b of the arm member 14 at approximately equal circumferential intervals. Although the illustrated spacer 15a uses a spring, it may be replaced with another one. This main member 15 is molded using a material having sufficient rigidity to collectively support the plurality of arm members 14, and may be molded into a polygonal ring shape instead of the circular ring shape shown.

The opening/closing member 16 is composed of a pair of links 17 and 18 that connect substantially central portions of adjacent arm members 14, and one end of each of the 14 arm members of each link 17 and 18 is connected to the arm member as shown in FIG. 14 via a pin 19a, and each link 19.18 is rotatable around the Y-Y axis (the length direction of the arm member 14). and Z-Z perpendicular to the Y-Y axis
It is also possible to rotate around the axis.

One end of each link 17, 18 on the side opposite to the arm member 14 side is bendably connected to each other via a common pin 23, but one link 18 is provided with a stopper 24, and each link 17.18 is fixed in a straight line position, and from this state the pin 2 toward the tread member 11 side is
Only refraction around 3 is possible (see Figure 4).

Further, a hook 25 having a hook hole 26 at the tip is attached to the pin 23 connecting each link 17, 18. This hook has gold 25 hook holes 26 for each link 17.1
8 may be provided directly.

The band-shaped elastic member 27 is made of a coil spring material having an elastic force capable of holding the tread member 11 mounted on the tread surface of the tire 42 in a tensioned state, and a hook 28 at one end in the length direction is attached to the opening/closing member 16. The hook is fixed to a hook hole 26 of the metal 25, and a hook 29 is also provided at the other end in the length direction.

A rubber material may be used instead of the coil spring material.

The fixing member 31 of the non-slip device attachment body 30 is a disc-shaped body with a shaft portion 32 provided in the center, and the stud of the automobile axle 50 provided on the disc portion 41 of the wheel 40 is attached to the peripheral edge thereof. A bolt hole is arranged on the same center as the bolt 51 insertion hole.

The rotating member 33 is a dish-shaped body provided with a bearing hole 34 in the center into which the shaft portion 32 of the fixed member 31 is fitted, and its outer diameter is larger than the diameter of the main member 15. has the same number of hook holes (latching portions) 35 as the band-like elastic member 27.
are provided at equal intervals in the circumferential direction. This hook hole 3
5 may be replaced with a hook.

In the tire anti-slip device having the above configuration, the anti-slip device attachment body 30 is attached in advance to the wheel of the automobile on which the device is to be mounted.

When attaching the anti-slip device attachment body 30 to the wheel 4o, attach the fixing member 31 via the nut 52 to the stud bolt 51 of the automobile axle 50 through which the disc portion 41 of the wheel 40 is inserted, adjusting the position of the bolt hole on the periphery. After inserting them together, tighten the fixing nut 53 onto the head of the stud bolt 51.
Screw together.

As a result, the fixing member 31 is in a fixed state with the shaft portion 32 positioned coaxially with the wheel 40. Next, the shaft portion 32 of the fixed member 31 is fitted into the bearing hole 34 of the rotating member 33, and the retaining ring 54 is attached to the tip of the shaft portion 32. Thereby, the rotating member 33 is in a state where it is rotatably attached around the shaft portion 320 of the fixed member 3I.

When attaching the anti-slip device main body 10 to the tire 42,
Each link 17, 18 of the opening/closing member 16 is extended in a straight line to open each arm member 14 radially. In this state, as shown in FIG. 6(a), the tread member 1
1 is placed over the tread surface on the top side of the tire 42 and encircled around the tread surface on the ground contact side of the tire 42, and then the band-shaped elastic member 27 is fixed to the opening/closing member 16.
The hook 29 at the tip of the wheel 40 is inserted into the hook hole 35 of the rotating member 33 of the anti-slip device attachment body 30 attached to the wheel 40.
(See Figure 2).

In this way, after temporarily installing the anti-slip device main body 10, when the car is started and the wheels 40 are rotated, the tires 4
Tread member 11 that was not covered with the tread surface of No. 2
As shown in FIG. 6 (C), the tread member 11 follows the movement of the wheel 40 and is gradually drawn into a predetermined position on the tread surface, and finally, as shown in FIG. This will cover the entire circumference of the tread surface of 42.

Since the anti-slip device main body 1° attached to the tire 42 is drawn toward the wheel 40 by the tension of the band-shaped elastic member 27, this force is applied to approximately the center of the arm member 14, and the main component 15 side of the arm member 14 is The end portion of the arm member 14 serves as a fulcrum on the rotating member 33 side of the anti-slip device attachment body 30 attached to the wheel 40, and the coupling fitting 13 of the 11 examples of the tread member of the arm member 14 is pressed against the tire 42. The force with which this coupling fitting 13 is pressed causes the tread member 11 to
is held on the tread surface of the tire 42.

The main member 15 is pressed against the rotating member 33 by the band-shaped elastic member 27 even while the tire 42 is running, and is held at a position substantially coaxial with the axis of the wheel 40.

When removing the anti-slip device main body 10 attached to the tire 42, the hook 29 of the band-shaped elastic member 27 is engaged and disengaged from the hook hole 35 of the rotating member 33 of the anti-slip device attachment body 30 attached to the wheel 40. After that, the other portions of the tread member 11 are removed from the tread surface of the tire 42 while leaving the ground-contact side portion of the tread member 11 as is. When the car is started in this state and the wheel 40 is rotated, the movement of the wheel 40 is The tread member 11 follows
is completely removed from the tread surface of the tire 42.

The anti-slip device body IO removed from the tire 42 is attached to the link 1 of the opening/closing member 16 as shown in FIGS. 7 and 8.
7.18 is bent toward the tread member 11 side using the pins 21.22 on the arm member 14 side as a fulcrum, and the links 17.18 are rotated around the mutual connection pin 23 and folded,
Connect each link 1718 to arm member 14 via hinge 19.20.
, and each arm member 14 is closed in an umbrella-like manner relative to the main member 15. At the same time, tread member 1
The individual treads 11a and Ilb of 1 are bent together via links 12 to form a reduced shape. As a result, the anti-slip device main body 10 has a small volume and is compact, and can be stored in the trunk of an automobile without taking up much space.

When the tread member 11 deforms according to the deflection of the tire 42 or changes its position on the tread surface while the wheel 40 equipped with this anti-slip device is running, the arm member 14 and the main member 15 may The locking portion 14b follows and moves in the radial direction to absorb the movement of the tread member 11.

In addition, the arm member 14 has a locking portion 14a at one end in the longitudinal direction rotatably coupled to the annular portion 13a of the coupling fitting 13 of the tread member 11, and a locking portion 14b at the other end in the lengthwise direction. The main member 15 to be coupled is pressed against the rotating member 33 of the anti-slip device anchoring body 30, and the portion of the arm member 14 other than the locking portion 14a on the tread member 11 side is attached to the side of the tire 42. Since it is spaced apart from the wall surface, even if the tire 42 bends while the wheel 40 is running, the locking portion 1 of the arm member 14 on the tread member 11 side
4a rotates and follows, and the arm member 14 itself does not receive the expansion force due to the deflection of the tire 42.

Further, while the wheel 40 is running, the tread member 11 rotates slightly less than the wheel 30.
Although the position of the tread member 11 in the circumferential direction with respect to the tire 42 is shifted due to the difference in rotation speed, the hook hole of the anti-slip device anchoring body 30 to which the hook 29 of the band-shaped elastic member 27 is engaged. 35 is provided on the rotating member 33 that rotates around the shaft portion 32 of the fixed member 31, so that even if the position of the tread member 11 relative to the tire 42 shifts, a forced tensile force will not act on the band-shaped elastic member 27. Therefore, breakage of the band-shaped elastic member 27 can be prevented.

In the embodiment, the arm member 14 of the anti-slip device main body IO.
The opening/closing member 16 and the band-like elastic member 27 are combined into a 6
Although the number of each of these members is provided in pairs, an appropriate number of three or more pairs may be selected depending on the size of the device, usage conditions, etc.

〔Effect of the invention〕

As explained above, according to the present invention, the tire slip prevention device is constituted by the anti-slip device main body and the anti-skid device attachment body, and the tire is attached to the engagement portion of the anti-slip device attachment body attached to the wheel. Since the hooks of the band-shaped elastic member of the attached anti-slip device body are to be engaged, the position and number of the engagement parts must be adjusted in advance in accordance with the position and number of hooks of the band-shaped elastic member to be engaged. An anti-slip device anchorage designed for this purpose can be attached to the wheel. For this reason, even if the wheel does not have ventilation holes or the number of ventilation holes is incorrect, it can be applied to all types and models of conventional wheels without making any modifications to the wheel itself. Not only can it be installed, but it also eliminates the drawback of not being able to stably perform the original function of the device as in the past.
A highly reliable tire slip prevention device can be obtained.

Further, according to the present invention, by bending the link of the opening/closing member of the anti-slip device main body, the arm members and the tread member can be opened and closed like an umbrella. The volume when removed from the container can be reduced, and the storage space can also be reduced.
