Description

[Technical field]

[0001] The present invention relates to an anti-skid device for vehicle tires, and more particularly to an anti-skid device in which an annular anti-skid band can be easily and reliably removed. Regarding. [Background technology]

[0002] 2. Description of the Related Art Conventionally, anti-skid devices are often used to reduce or prevent tires from slipping on icy roads during severe winters.

[0003] For example, an anti-slip device is known in which the inner wheel sides of multiple anti-slip bands are connected with a connecting member and a pulling member is provided between the outer wheel sides, the multiple anti-slip bands are placed over the tread surface of the tire, the inner wheel sides of adjacent anti-slip bands are connected in a ring shape, and the outer wheel sides are pulled in the longitudinal direction to fit tightly against the tread surface of the tire (Patent Document 1).

[0004] Also, an anti-slip device has been proposed in which an annular anti-slip band is made of woven fiber fabric and is fitted over the tread surface of a tire (Patent Document 2).

[0005] Furthermore, an anti-slip device has been proposed (Patent Document 3) in which an annular anti-slip band is made oversized compared to the tire diameter using a fiber fabric woven with warp and weft threads, the annular anti-slip band is placed over the tire tread surface, and the anti-slip band is pulled in and reduced in diameter by an elastic member on at least the inner wheel side of the tire, suppressing the anti-slip band from lifting up against the tire tread surface and preventing the anti-slip band from coming off the tire when traveling at high speeds.

[0006] [Patent Document 1] JP 2022-136456 A [Patent Document 2] Special Publication No. 2002-541007 [Patent Document 3] JP 2011-51588 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0007] However, in the tire anti-slip device described in Patent Document 3, at least the inner wheel side of the annular anti-slip band is tightened with an elastic member, so when trying to remove the anti-slip band, an operator must insert their hand into the inner wheel side of the tire and hook their hand onto the edge of the anti-slip band and pull it.However, this stretches the elastic member, making it difficult to smoothly remove the edge of the anti-slip band. Furthermore, since the annular anti-slip strip is made of a woven fiber fabric made of warp and weft threads, the anti-slip strip tends to adhere firmly to the tire tread, making it difficult to remove.

[0008] SUMMARY OF THE PRESENT EMBODIMENT In view of the above problems, an object of the present invention is to provide an anti-skid device for vehicle tires that enables an annular anti-skid band to be easily and reliably removed. [Means for solving the problem]

[0009] Therefore, the anti-slip device for vehicle tires according to the present invention is provided with an anti-slip band, which has flange portions on the inner wheel side and outer wheel side of the annular body, the annular body being made of a woven fabric made of woven fibers, and an elastic member being provided on at least the edge of the flange portion on the inner wheel side of the tire, the annular body of the anti-slip band being placed over the tread surface of the tire, and the annular body of the anti-slip band being configured to be pulled by the elastic member to reduce its diameter, while a gripping tongue is formed on the edge of the flange portion on the inner wheel side and / or outer wheel side of the annular body of the anti-slip band, and the gripping tongue is gripped by the fingers of an operator to pull the edge of the flange portion on the inner wheel side or outer wheel side of the tire, thereby allowing the anti-slip band to be removed.

[0010] One of the features of the present invention is that a gripping tongue is formed on the flange portion of the inner side, outer side, or inner and outer side of the tire, which can be gripped and pulled by the worker's fingers.

[0011] This allows an operator to insert his or her hand into the inner wheel side of the tire, grasp the gripping tongue with his or her fingers, and pull to easily and reliably remove the annular anti-slip band. Furthermore, by hooking and pulling the gripping tongue on the outer wheel side of the tire with the worker's fingers, the annular anti-slip band can be removed easily and reliably.

[0012] The material of the fiber fabric is not particularly limited, and any known material can be used. The weaving method of the fiber fabric is not particularly limited, and may be any of plain weave, twill weave, and satin weave. [Brief description of the drawings]

[0013] [Figure 1] 1A and 1B are diagrams showing the outer wheel side and the inner wheel side of a preferred embodiment of an anti-skid device for a vehicle tire according to the present invention. [Diagram 2] FIG. 2 is a diagram showing a main part of the embodiment. [Diagram 3] FIG. 13 is a diagram showing a main part of a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The present invention will be described in detail below with reference to the specific examples shown in the drawings. Figures 1 and 2 show a preferred embodiment of an anti-skid device for a vehicle tire according to the present invention. In the drawings, The anti-slip band 11 is provided as a main component of the stop device 10, and the anti-slip band 11 has flanges 13, 14 on the outer and inner sides of an annular body 12. The annular body 12 is knitted using warp and weft threads to a diameter larger than the outer diameter of the tire 20 by a predetermined dimension, and the flanges 13, 14 are made of a mesh material. The materials of the warp and weft threads are not particularly limited, and known materials can be used. The annular body 12 and the flanges 13, 14 may be knitted and manufactured as an integral unit.

[0015] In addition, an elastic ring (elastic member) 15 is attached in a tensioned state to the edges of the outer ring side flange portion 13 and the inner ring side flange portion 14 of the anti-slip band 11, so as to urge the edges of the outer ring side flange portion 13 and the inner ring side flange portion 14 in the pulling direction.

[0016] Furthermore, radially elongated gripping tongues 16 are attached by stitching at a predetermined angular interval to the back surface of the edge of the inner wheel side flange portion 14 of the anti-slip band 11, and when the edge of the inner wheel side flange portion 14 of the anti-slip band 11 is pulled by the worker's fingers and the gripping tongues 16 are grasped, the edge of the flange portion 14 on the inner wheel side of the tire of the annular body 12 of the anti-slip band 11 is pulled in the removal direction.

[0017] The direction in which the anti-slip device 10 is attached to the tire 20 is known for the anti-slip devices of Patent Documents 2 and 3, and therefore a detailed description thereof will be omitted.

[0018] When removing the anti-slip device 10, an operator can insert his / her hand into the inner wheel side of the tire 20 and move his / her hand along the edge of the inner wheel side flange portion 14 to find the gripping tongue 16. Then, by pulling the edge of the inner wheel side flange portion 14 of the annular body 12 of the anti-slip band 11 with his / her fingers and grasping and pulling the gripping tongue 16, the anti-slip band 11 can be securely removed from the tire 20.

[0019] Fig. 3 shows a second embodiment, in which the same reference numerals as in Fig. 1 and Fig. 2 indicate the same or corresponding parts. In the first embodiment, the gripping tongue 16 is provided on the back surface of the edge of the flange portion 14 of the annular body 12 of the anti-slip band 11 on the tire inner wheel side, but it may also be provided on the back surface of the edge of the flange portion 14 of the annular body 12 of the anti-slip band 11 on the tire outer wheel side. It is also possible to provide the anti-slip band 11 only on the rear surface of the edge of the flange portion 14 of the annular body 12 of the anti-slip band 11 on the outer wheel side of the tire.
