[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-slip device which prevents slipping of a tire which is mounted on an outer peripheral portion of a tire of an automobile when traveling on a snowy road or a frozen road.

[0002]

2. Description of the Related Art Recently, as an anti-skid device for a tire, a plurality of non-slip belts formed of elastic material such as synthetic resin in a belt shape or a knotted net shape between two parallel side ropes are appropriately spaced. There is known a tire non-slip device in which a blade or a spike is fixed to the surface of the tire, which is arranged in a ladder shape and is in contact with the road surface. (See, for example, Japanese Utility Model Laid-Open No. 64-40706).

[0003]

In the conventional anti-skid device, when it is attached to a tire, it is usually applied to the outer rope or the outer side of an anti-slip belt formed in a knot net shape as the last work. A method of attaching a fixing band to the C-shaped hook, tensioning it toward the center, and mounting it on the tire is adopted. However, in recent years, since a greater anti-slip effect is required, the mesh shape of individual anti-slip belts and the connecting portion also have a more complicated structure, and accordingly, a tough material is naturally adopted. However, by simply hooking the conventional C-shaped hook on the outer rope or the outer side of the non-slip belt and simply tightening it with the fixing band toward the center side, the individual anti-slip belts can be sufficiently stretched along the tire surface. In addition, it is difficult to secure an appropriate size for the connection distance between the individual anti-slip strips on the outer side, and therefore the outer side of the anti-slip wear is more than the inner side of the slipper until the final work when tightening with the fixing band. The length of the side is long enough to fit easily on the tire, and when tightening with the final fixing band, the pulling force of the individual anti-slip belts along the surface of the tire and the individual slippage. Of strap The secure dimension of the binding interval is guaranteed, and after tightening with the fixing band, the center part of the tire anti-slip band swells to the optimum shape that closely adheres to the tire surface, and the tire anti-slip band is It is an object of the present invention to provide a slip preventer for a tire that can be correctly mounted at right angles to the forward direction of the vehicle.

[0004]

In order to achieve the above-mentioned object, a slip preventer for a tire according to the present invention is a hook body in which a hook of a fixing band is bent forward in a U shape at the tip of a lower half portion. In the longitudinal direction, a long groove is provided in parallel with the hook, and at the upper end of the long groove, a pulling groove communicating with the long groove is provided at a right angle to the long groove. The connecting wheels inserted into the outer ends of the front and rear side strips are loosely fitted.

[0005]

[Operation] When the main body of the hook is laid down sideways, one connecting wheel can be positioned at one end of the long groove and the other connecting wheel can be positioned in the pulling groove, so that the distance between the left and right connecting wheels can be increased. When the hook main body is raised vertically with the hooks on the bottom so that the fixing band can be hung, the connecting wheels in the long groove slide in the long groove and both connecting wheels gather in the pulling groove. ,
Because the left and right connecting wheels are attracted due to the gap between the two connecting wheels, the outer edge of the non-slip belt is also drawn together, and the center position of the anti-slip belt is inflated along the tire surface. Alternatively, the widths of the inner and outer sides can be made equal by ensuring an appropriate connection interval dimension, and the tire can be mounted at a right angle to the traveling direction of the tire.

[0006]

EXAMPLES Examples will be described with reference to the drawings. 1 to 4, the hook 1 for hanging the fixing band is made of, for example, iron or iron wire, and the lower end side (left side in FIG. 1) is bent forward in a U shape to hook the fixing band. Form the hook 2. Reference numeral 3 denotes a long groove provided in the hook body 4 in the direction parallel to the hook 2 in the longitudinal direction from the lower end of the hook body 4 toward the upper end. The attracting groove 5 is provided on the upper end side of the long groove 4 so as to communicate with the long groove 4 in the direction perpendicular to the long groove 4 and to be provided. The connecting wheels 6 and 6 are formed by bending, for example, an iron wire into a substantially O shape, and one end of the bent wheel has a long groove 3 and an attracting groove 5.
Each of them is loosely fitted inside, and the other end side is inserted into each of the front and rear side strips 8 of the anti-slip strip 7 and the end portions 9 outside (downward in FIG. 1) of the strips 8.

Further, in FIG. 5, when the anti-slip band 10 has a narrow width, the bent one ends of the connecting wheels 6 are inserted into one ends of the connecting rods 11 attached to the outside of the anti-slip band 10. To do.

[0008]

Since the present invention is constructed as described above, it has the following effects. When mounting on the surface of the tire, keep the hook body in the horizontal direction until it completely covers the surface of the tire.One connecting wheel is located at the lower end of the long groove, and the other connecting wheel is in the pulling groove. Since it is located at, the distance L between the side bands can be ensured to be long enough to be easily attached to the tire, and when the hook body is raised with the hook hook down, the fixed band A is naturally raised. One of the connecting wheels from the lower end side of the long groove slides in the long groove and fits into the attraction groove, and the left and right side surface bands 8 and 8 are attracted to the inside, so that the width between the side surface bands is smaller than L. The center of the non-slip belt body reduced in size to 1 and formed into a knotted net can bulge and be surely along the curved tire surface. In addition, the width of the non-slip strips is narrow, and if a hook is provided between the connecting rods of the adjacent non-slip strips, the spacing between the connecting rods on the outside of the anti-slip strips can be widened for easy mounting, By raising the hook so that the fixing band can be hung, the widths of the inside and outside sides of the anti-skid device become the same, and it is possible to more reliably attach the anti-slip device at right angles to the traveling direction of the tire.
