Abstract

PURPOSE:To provide slip prevention effect of wheel easily and sufficiently by installing a tension pulley so as to press the loose side of a slip prevention belt which is detachably wound around a driven wheel and a wheel so that it may be attached and removed to or from them. CONSTITUTION:A pair of slip prevention devices 2 are installed on both sides of a wheel 1. Namely, a driven wheel 4 is installed rotatably through the first support plate 5 which is vertically-installed on the vehicle 1, being positioned at the rear side of a wheel 3 as a driving wheel. Besides, a slip prevention belt 7 is detachably wound around the wheel 3 and the driven wheel 4. The slip prevention belt is formed with both peripheral parts 7a, 7b of endless shape each inside of which is made into a little 'R', and a number of small projections 8 for slip prevention are formed on its outer peripheral surface 7c. Moreover, a tension pulley 9 is rotatably installed at one end part of an arm 10 which is journaled to the vehicle 1 so as to press the loose side of the slip prevention belt 7. When the slip prevention belt 7 is used, the vehicle 1 is lifted up, and the slip prevention belt 7 is wound around the wheel 3 and the driven wheel 4 to rotate the slip prevention belt 7 and the wheel 3 together.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a slip prevention device for automobile wheels, which has a function as a substitute for tire chains attached to automobile wheels.

``Prior Art'' Generally, during snowfall in winter, vehicles run with tire chains attached to their wheels to prevent slipping. However, attaching and detaching this tire chain is troublesome.

Therefore, there is currently a demand for an automobile wheel slip prevention device that can function as a substitute for tire chains.

[Problems to be Solved by the Present Invention] In view of the above-mentioned conventional problems, the present invention has a function as a substitute for tire chains, and also provides an anti-slip belt to the wheels compared to the conventional work of attaching and detaching tire chains. An object of the present invention is to obtain an anti-slip device for an automobile wheel which can be easily installed and removed and which can sufficiently prevent the wheels from slipping.

``Means for Solving Problem U'' In order to achieve the above object, the automobile wheel slip prevention device of the present invention includes a wheel as an original vehicle and a support plate provided in front or behind the wheel. A freely movable driven vehicle, an anti-slip belt removably wrapped around the driven vehicle and the wheels, and an anti-slip belt pivotally supported on the vehicle so as to be able to hold down the slack side of the anti-slip belt. It is characterized by consisting of a tension wheel rotatably provided at one end of the arm.

``Example'' The present invention will be described in detail below using examples shown in the drawings.

1 to 5 show an embodiment of the present invention.

1 is a vehicle. Although this embodiment shows an ordinary passenger car, it may also be a freight vehicle such as a dump truck.

Reference numeral 2 denotes an automobile wheel slip prevention device attached to the vehicle 1. This anti-slip device 2 is constructed as shown in FIGS. 2 and 3, and is installed in pairs on the left and right sides of the vehicle 1.

Therefore, 3 is the wheel as the original vehicle. In this embodiment, it is the rear wheel of a normal passenger.

Reference numeral 4 designates a follower vehicle which is located on the rear side of the wheels 3 and is rotatably provided via a first support plate 5 which is fixedly vertically installed on the vehicle 1. This follower vehicle 4 is pivotally supported by a first horizontal shaft 6 fixedly provided on a first support plate 5, as shown in FIG. Note that the follower vehicle 4 may be provided in front of the wheels 3.

Reference numeral 7 denotes an anti-slip belt that is removably wrapped around the wheels 3 and the follower vehicle 4, respectively. This anti-slip belt 7
As shown in FIGS. 4 and 5, both endless end edges 7a and 7b are formed slightly rounded inwardly, and 1. A large number of small protrusions 8 for preventing slippage are formed on the outer peripheral surface 7C.

Reference numeral 9 denotes a tension wheel rotatably provided at one end of an arm 10 pivotally supported on the vehicle 1 so as to be able to hold down the slack side of the anti-slip belt 7. The arm 10
is located in front of the first support plate 5 in this embodiment,
Further, it is provided via a support shaft 12 at the lower end of a second support plate 11 fixedly vertically installed on the vehicle 1 . Further, a weight 13 is attached to the other end of the arm 10. Therefore, the arm 10 plays the role of a lever using the support shaft 12 as a fulcrum.

In addition, in this embodiment, the first support plate 5 and the second support plate 1
Both support plates 5. and 1 are shown separately.
11 may be integrated.

Function J In the above configuration, when using the anti-slip belt 7, first lift the vehicle 1 appropriately using a portable jack (not shown), then attach the anti-slip belt 7 to the wheels 3 and the follower vehicle 4. At this time, lift the weight 13 slightly by hand so that the tension wheel 9 does not get in the way, and separate the tension wheel 9 from the anti-slip belt 7.

Therefore, the anti-slip belt 7 has a slack side on the tensioned wheel 9.
It rotates together with wheel 3 when it is strongly pressed.

"Effects of the Invention" As is clear from the above explanation, the present invention has the following effects.

(1) It has a function as a substitute for a tire chain, and the anti-slip belt 7 can be easily attached and detached from a wheel compared to the conventional attachment and detachment work of a tire chain.

(2) A sufficient wheel slip prevention effect can be obtained.
