DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-slip mechanism for an automobile, and more particularly, to an anti-slip mechanism that can be easily attached to and detached from a tire when running in snow or in a mud. The present invention relates to a non-slip mechanism for a vehicle.

[0002]

2. Description of the Related Art In a vehicle such as an automobile, a chain or the like is generally used as a non-slip when snow is snowing or the like, and a spike tire or a snow tire is used. However,
In the case of a chain, many people are unfamiliar with chain mounting, and in such a case, the vehicle body is once lifted with a jack and mounted, and the same applies to spike tires and snow tires. Since attaching and detaching the anti-slip is complicated as described above, it places a considerable burden on female drivers and the like.

[0003] In view of such a problem, the present inventor has previously described, "Attaching a pulley rotatably to a shaft protruding sideways concentrically with the tire, and adjoining the pulley close to the tire. A plurality of arms (supports) each having a substantially hook shape extending from the side wall to the inner side wall beyond the tread surface and having a non-slip ridge at a portion corresponding to the tread surface are rotatably mounted, and two arms are provided between the supports. An elastic non-slip band in which a number of anti-slip ridges are laid across the elastic arcs is attached so as to surround the tread surface of the tire except for a ground contact portion, and a driving wire (string) is provided between supports at the ends of the anti-slip band. ), The other end of the cord is attached to the pulley, and the pulley is rotated to wind up the cord, whereby the support rotates around the tire to extend the elastic arc of the non-slip band. Thailand with the support , And the strap is released from the ground contact portion of the tire together with the support by releasing the winding of the string on the pulley. See JP-A-62-83024).

In order to mount the non-slip around the tire, a tool is inserted into a tool hole for mounting and the pulley is rotated to spread the non-slip around the tire. In order to remove the non-slip, you can remove the non-slip from around the tire by pulling the wire by operating from the driver's seat, so workability is easier than when handling chains etc. by hand Can be greatly improved.

[0005]

However, in the case of the anti-slip mechanism for a vehicle as described above, there are the following problems. That is: 1) The work of attaching the anti-skid around the tire still needs to be done manually by a person going out of the car. Therefore, when the snow starts suddenly, the driver has to work while exposing himself to the falling snow, and is forced to work hard. 2) Since a special tool is required to install the non-slip, if this tool is not provided on the car, the non-slip cannot be installed and the vehicle will get stuck on the road. 3) In this way, even though the removal of the non-slip can be operated easily, the mounting procedure is troublesome as in the case of mounting a conventional chain, and it is not possible to quickly respond to sudden snowfall. And other issues.

The spike 3b has a shape that is wrapped around the tread surface 50a of the tire 50 from the wheel 51, and a spike 3b having an arc-shaped cross section is formed on the surface corresponding to the tread surface 50a. Similarly, the other arms 4 to 6 also form bases 4a to 6a and are rotatably connected to the pulley 2, and have spikes 4b to 6b at portions corresponding to the tread surfaces 50a.

Between the first arm 3 and the second arm 5 except between the first arm 3 and the fourth arm 4, the second arm 5 and the third
Between the arm 6 and between the third arm 6 and the fourth arm 4, a pair of connectors 7 running on both side surfaces of the tire 50 are respectively incorporated. The connector 7 is formed of a stretchable elastic material using rubber or other suitable synthetic resin, and a metal roller 7

6 are rotatable independently of each other, but are connected to each other by a telescopic connector 7 except between the first arm 3 and the fourth arm 4, so that they are interlocked with each other around the pulley 2. And rotate.

As shown in FIG. 2, the first arm 3 has a U
A letter-shaped guide tube 8 is attached, and a drive wire 9 is inserted through the guide tube 8. This drive wire 9 is
The distal end of the arm 4 is guided by a guide roll 4d provided on the distal end side of the arm 4, and is connected to the pulley 2 through a flexible tube 10 provided between the arm 4 and the outer peripheral surface of the pulley 2 (see FIG. 3). . Therefore, in FIG.
When rotated in the counterclockwise direction, the drive wire 9
And the first arm 3 is
In FIG. 1, the arms 4 to 6 connected by the connector 7 at the same time as they move in the counterclockwise direction are also changed in position as shown in FIG. For this reason, the roll 7a of the connector 7 and each arm 3
To 6 spikes 3b to 6b are developed over the entire circumference of the tread surface 50a of the tire 50.

FIG. 5 is an enlarged cross-sectional view showing the details of the pulley 2 and the clutch mechanism and the brake mechanism connected thereto, which correspond to the state of FIG. A base plate 11 is incorporated as a separate body on the surface side of the pulley 2, and the base plate 11 is attached to the axle 1 and the pulley 2 so as to be non-rotatable. Using the base plate 11, a clutch mechanism and a brake mechanism and their driving systems are mounted. The clutch mechanism includes a clutch plate 12 attached to a spline 1b at the tip of the axle 1. Transmission and disengagement of the driving force can be performed by the clutch teeth 2a of the pulley 2 and the clutch teeth 12a of the clutch plate 12. As shown in FIGS. 1 and 4, proximity switches A to E are provided on the base plate 11 at predetermined intervals, and strikers 29 for operating the proximity switches A to E are provided on the arms 3 to 6. .

Next, returning to FIG.
A support rod 13 connected to the vehicle body 20 is fixed to the left side of the vehicle (see FIG. 11), and a clutch wire 14 is wired along the support rod 13. Clutch wire 14
Is an auxiliary block 1 wired to an output device 21 provided on a vehicle body 20 and slidably provided on a support rod 13.
3a is connected to one end thereof. And the output device 21
Is connected to the operation unit 24 of the driver's seat 23 via the control unit 22. On the other hand, the auxiliary block 13a is urged rightward by an operation spring 13b in FIG. 1 and is connected to a spring 11a on the base plate 11 side by a connection wire 13d.

As shown in FIGS. 1 and 4, the spring 11a is pivotally connected by a pin 11b at one end thereof and away from the auxiliary block 13a. Are connected to the connection wire 13d. The spring 11a rotates the clutch plate 1 counterclockwise in FIGS.
The clutch teeth 2a and 12a are normally disengaged. Therefore, in this state, even if the axle 1 rotates, the rotation is not transmitted to the pulley 2, and the pulley 2 remains stopped together with the bearing 1 a against the rotation of the axle 1.

When the clutch device 12 in the state shown in FIGS. 1 and 2 is operated in the direction in which the clutch wire 14 is pulled by the output device 21, the spring 11a connected to the connection wire 13d is biased. It is deformed in the opposite direction. For this reason, the clutch teeth 2a and 12a in the disengaged state as shown in FIGS. 2 and 5 mesh with each other as shown in FIG. Therefore, when the axle 1 rotates, the pulley 2
, And the pulley 2 rotates integrally with the tire 50.

On the other hand, the brake mechanism includes a brake drum 4c formed on the base 4a of the fourth arm 4 and a brake shoe 15 that slides on the brake drum 4c. As shown in FIGS. 5 and 6, the brake drum 4c is integrated with the base 4a, and the brake shoe 15 is
Shoe case 15 connected and fixed to stay 15b
a.

FIG. 7 is an exploded perspective view showing a main part of a brake shoe 15 and a member for driving the brake shoe 15 by a brake wire 16. The brake shoe 15 is, for example,
The outer peripheral surface side is elastically deformable backed by a spring steel 15c. One end of the spring steel 15c is fixed and the other end is movable, so that the brake shoe 15 is attached to the peripheral surface of the brake drum 4c. It is configured to perform an operation of abutting or moving away from it. For such an operation, a bracket 17 is provided on the base plate 11 as shown in FIG. 1, and a rotator 18 rotatably connected to the bracket 17 is provided.

The bracket 17 is fixed to the base plate 11, and a pin 17a protruding from the back of the bracket 17 is
5c. On the other hand, a rotator 18 having one end connected to the brake wire 16 is rotatably connected at an intermediate portion thereof by a pin 17b of a bracket 17, and the other end is connected to the other end. Pin 18a provided on the part
Is inserted into one end of the spring steel 15c. With this configuration, one end of the spring steel 15c is restrained by the bracket 17, and when the brake wire 16 is pulled in the direction of the arrow in FIG. 7, the rotator 18 rotates clockwise around the pin 17b,
This winds up the spring steel 15c. Therefore, the inner diameter of the brake shoe 15 is reduced, and the brake shoe 15 can contact and brake the brake drum 4c.

Further, between the first arm 3 and the support rod 13, there is provided a lock mechanism (or an arm reverse prevention mechanism) for holding the first arm 3 when the first arm 3 is set at the mounting position. ing. As shown in FIGS. 1 and 5,
A movable element 19 is extrapolated to the base end of the first arm 3, and the movable element 19 is urged toward the base 3a by a spring 19a. The movable member 19 is provided with a retracting roller 19b on the front side and a locking roller 19c on the back surface of the distal end portion. On the other hand, as shown in FIG. 1, a notch 4a large enough to fit the lock roller 19c around the periphery of the base 4a of the fourth arm 4.
-1 is provided. In addition, an evacuation roller 19b abuts on an auxiliary block 13a provided on the support rod 13, and at this time, a projection 13c for moving the movable element 19 to the left in the drawing is provided.

FIG. 8 is a schematic view corresponding to FIG. 4, in which the lock roller 19c is fitted in the notch 4a-1. FIG.
FIG. 5 is a schematic diagram showing a positional relationship between the moving member 19 and the projection 13c when the first arm 3 overlaps the support rod 13 concentrically. The retracting roller 19b is located outside the projection 13c, and when the first arm 3 rotates counterclockwise, the retractor 19b operates freely without the retracting roller 19b interfering with the projection 13c. When the first arm 3 moves and comes to the state shown in FIG. 8, the movable element 19 urged by the spring 19a moves to the base 4a side of the fourth arm 4 when the first arm 3 moves and the state shown in FIG. It moves and the locking roller 19c at the tip thereof is notched 4a-1.
It is configured to fit inside. Thus, the first arm 3 and the fourth arm 4 which are connected to each other by the connector 7 and located at both ends are locked by being restrained between the locking roller 19c of the movable member 19 and the notch 4a-1. (See FIG. 8). In this state, the auxiliary block 13 of the support rod 13 is
By moving a to the left in the drawing, the protrusion 13c pushes the retraction roller 19b, and the moving element 19 moves outward from the base end of the first arm 3 as shown in FIG. 19b can ride on the projection 13c and release the restraint by the lock roller 19c.

In the above configuration, in the state shown in FIGS. 1 and 2, the non-slip is held at a position away from the tire 50, and the non-slip has no relation to the rotation of the tire 50. That is, the clutch teeth 12a of the clutch plate 12
The clutch teeth 2a of the pulley 2 are disengaged, and the roller 7a of the connector 7 and the distal ends of the arms 3 to 6 are separated from the tread surface 50a of the tire 50. And brake wire 1
Reference numeral 6 denotes a pulled state, in which the brake shoe 15 tightens around the brake drum 4c and regulates the rotation of the fourth arm 4.

As described above, the disengagement of the clutch mechanism and the operation of the brake allow the tire 50 to travel when the vehicle is running.
The arms 3 to 6 and the rollers 7a keep the tire 50
And the pulley 2 is kept stationary even when the axle 1 rotates. For this reason,
When normal running is possible without snow on the road, only the tire 50 rotates and the non-slip does not hit the road surface.

Next, the operation of attaching and detaching the anti-slip mechanism of this embodiment to and from the tire 50 will be described. First, the non-slip around the tire 50
During this rotation, the clutch mechanism and the brake mechanism are simultaneously operated. That is, when the operation unit 24 arranged in the driver's seat 23 shown in FIG.
The clutch motor 26 shown in FIG.
8, the clutch wire 14 is loosened, and the spring 11a pushes the clutch plate 12 toward the pulley 2 as shown in FIG.
a and 12a are engaged with each other. On the other hand, the operation of the brake mechanism is continued, and the rotation of the fourth arm 4 is regulated. When the tire 50 rotates in the forward direction of the vehicle body (counterclockwise in FIG. 1), the drive wire 9 is wound around the rotating pulley 2 as shown in FIG. At this time, since the fourth arm 4 is maintained in the stopped posture, the other arms 3, 5, and 6 connected by the elastic connector 7 move in a direction of developing around the tire 50. FIG. 4 shows a state in which the arms 3 to 6 have been deployed, and the locking roller 19c of the mover 19 provided in the first arm 3 fits into the notch 4a-1 of the fourth arm 4, and The arms 3 to 6 are set around the tire 50 in the posture shown in the state of FIG. And at this time,
The tire 5 is formed by the tips of the arms 3 to 6 and the roller 7a.
A non-slip is formed around the 0 peripheral surface.

After the non-slip is mounted around the tire 50 in this manner, the vehicle is driven and the proximity switches A and B are driven.
Simultaneously operate (the state of FIG. 2), the brake motor 27 operates, the moving nut 28 moves to the right in FIG. 12, the brake is released, and the non-slip mounting on the tire 50 is completed. . The arms 3 to 6 connected around the pulley 2 rotate integrally with the tire 50 due to the friction between the tire 50 and the ground contact portion on the road surface. Therefore, according to the running of the tire 50, each of the arms 3 to 6
Can rotate integrally with the relationship of the posture shown in FIG. 4 and can travel on the road surface with the tips of the arms 3 to 6 around the tire 50 and non-slip by the roller 7a.

Further, when the anti-slip is removed from around the tire 50, the clutch mechanism is disengaged while the tire 50 is slowly rotated to run. That is, when the operation section 24 of the driver's seat section 23 is operated, the clutch motor 26
Is operated, the moving nut 28 moves to the left, the clutch wire 14 is pulled to the left in FIG. 5, and the auxiliary block 13a also moves together. Then, as described with reference to FIG. 10, the first block is moved by the movement of the auxiliary block 13a.
The mover 19 of the arm 3 also moves to the left, the roller 19b rides on the protrusion 13c, and the lock roller 19c
The arm 4 comes out of the notch 4a-1. Then, the arms 3 to 6 which have formed the wheels return to the original interval shown in FIG. 1 by the elastic force of the connector 7 while rotating integrally with the tire 50, and the roller 7 a also separates from the tread surface 50 a of the tire 50.

The anti-slip spikes 3b to 6b
When is located on the road surface, it receives the rotational force of the wheels, and generates its own inertial force and rotational force due to friction between the support shaft 1 and the bearing 1a. The non-slip rotates with the wheel as long as the wheel rotates at a certain speed or higher. Therefore, when the automobile is driven at a certain speed or more, the anti-slip rotates, and when the arms 3 to 6 come to the position shown in FIG. 1, the brake wire 16 is pulled, the brake drum 4c is tightened by the brake shoe 15, and the fourth arm When the lock 4 is locked, the other arms 3, 5, 6 are restrained at the positions shown in FIG. 1, and only the tire 50 can rotate. Here, when the speed of the vehicle is higher than a certain speed, when the proximity switch C of FIG. 1 is operated by the striker 29 of the fourth arm 4, the brake motor 27 is operated, and the moving nut 28 is about half in FIG. The nut moves to the left, and the moving nut 28 stops with the brake slightly applied. When the speed is lower than the predetermined speed, the brake motor 27 does not operate even if the proximity switch C operates. Further, when the proximity switches D and E are simultaneously operated, the brake motor 27 is operated again, and the moving nut 28 is moved to the left movement limit in FIG. 12, and the braking effect is maximized. 4
Is held at a substantially predetermined position, and the removal of the non-slip is completed.

As described above, the anti-slip attachment / detachment mechanism for a vehicle according to the present embodiment uses the clutch wire 14 and the brake wire 16 for operating the clutch mechanism and the brake mechanism, respectively, and allows the vehicle to slide while traveling. The stop can be easily attached to and detached from the tire 50, so that the driver does not need to work outside the vehicle even in a sudden snowfall.

It should be noted that the present invention is not limited to the above-described embodiment, but includes a configuration that can be modified and implemented without changing the gist of the present invention. Incidentally, in the above-described embodiment, the description has been made in the form of the band brake as the brake mechanism. However, a configuration using an electromagnetic brake or the like may be used.
Also, the case of four arms has been described, but the number of arms may be five or more, or three.

Claims (1)

(57) [Claims] 1. A pulley is rotatably mounted coaxially with an end of an axle passing through a wheel of a tire, and an annular base having a base end rotatably connected around the pulley is provided around the pulley. N arms including a first arm to an N-th arm that cover and extend from the side surface to the tread surface of the tire, and a pair of adjacent arms between the first arm and the N-th arm are provided on the side surface of the tire. Along with the pulley, one end of a driving wire is connected to the pulley, and the other end of the driving wire is connected to the Nth arm and the first arm which are not connected by the connector. Connected to the first arm via the N-th arm so as to be able to freely separate from each other, the tip of the n arms and the connector covering the tread surface of the tire as a non-slip, and between the pulley and the axle. Kula A clutch mechanism, a brake mechanism between the pulley and the N-th arm, and operating the clutch mechanism and the brake mechanism, whereby the n arms are connected via the connector and the drive wire. A non-slip attachment / detachment mechanism for an automobile that is capable of being deployed and folded over the entire circumference of the tire, wherein an operation unit for operating the clutch mechanism and the brake mechanism is arranged in a driver's seat of the automobile, an arm reversing prevention mechanism for preventing the n arms from returning to the original state when the n arms are deployed in the entire surrounding of the tire; and engaging the axle and the pulley with the clutch mechanism. Rotating the pulley integrally with the axle, applying a brake to the Nth arm by the brake mechanism to generate a rotation difference between the pulley and the arm, and The n arms are deployed to the entire surroundings of the tire by winding the wire around the pulley against the elastic force of the connector, and after the deployment is completed, the arm is prevented from rotating by the arm reverse rotation preventing mechanism. The distance between the N-th arm and the first arm, which are connected with each other, is fixed to prevent reverse rotation of the arm, and the brake by the brake mechanism is released to complete the mounting of the non-slip. The mounting means and the clutch mechanism disengage the engagement between the axle and the pulley, and the arm reversing prevention mechanism releases the fixed state between the Nth arm and the first arm connected by the drive wire. The n arms are folded back to the original state by the elastic force of the connector, and the n arms are rotated by the brake mechanism while rotating together with the tire. Serial slip detaching mechanism for a motor vehicle, characterized in that it comprises a slip removal means complete removal of the slip by locking the first N arms in place.
