Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a non-slip member for a vehicle that is attached to the tires of an automobile or the like on snowy days.

(Prior Art) Conventionally, as anti-slip devices for vehicles that are attached to tires, for example, those shown in Japanese Patent Publication No. 57-53201, or those shown in FIG. 18 or 19 have been developed.

(Problem to be solved by the invention) However, the former anti-slip member (Japanese Patent Publication No. 57-53201) in the above-mentioned conventional anti-slip device for vehicles consists of a mere narrow rod-shaped body made of rubber or synthetic resin. Therefore, when used attached to a tire, there is a problem in that an impact occurs in the space between the anti-slip members, and the latter (Fig. 18 or 19) Since both end portions 11a and 11b of 11 are inserted and engaged with each other in an overlapping manner as shown in FIGS. 20 and 21, the above-mentioned overlapping is inevitable. One of the shaped insertion and locking parts protrudes from the road surface 11c, and this part is prone to wear and breakage more quickly than other parts due to friction with the road surface, and is also susceptible to impact. Along with Atsuta, the above model has a part that is wrapped along both sides of the tire (both sides in the longitudinal direction).
However, due to the self-elastic stress of the net body 11, the net body 11 attempts to restore itself to its original flat state, and as a result, there is not only a fear that the net body 11 may easily come off from the outer circumferential surface of the tire, but also that it will not conform to both sides of the tire. Since both ends of the connecting portion of the net main body are connected in an overlapping state, there are problems such as not being able to adjust the winding dimensions to a large extent according to the size of the tire.

The present invention solves the above problems and connects both ends of the net main body without overlapping, thereby eliminating friction caused by overlapping protrusions, preventing early breakage of the connecting part, and reducing impact caused by the protrusions. In addition, the width of the net-like anti-slip member is made approximately equal to the width of the outer circumferential surface of the tire (tread surface), and at least one to several ladder-like anti-slip members are formed in the net-like anti-slip member. The rope connector locking tongue pieces of the parallel strips on both sides of the net-shaped anti-slip member are locked to the cables, and reinforcing core materials are integrated into the parallel strips on both sides and the diagonal strips, respectively. By molding the net-like anti-slip member into It is an object of the present invention to provide a non-slip member for a vehicle whose winding dimensions can be adjusted over a wide range according to the size of the vehicle.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is a non-slip member for a vehicle that is attached to a tire and is made of an elastic material such as rubber or synthetic resin to prevent the outer peripheral surface of the tire from slipping. A ladder-like non-slip member formed with an inner shape and a required width that can be adapted to both side surfaces, and at least one to several ladder-like non-slip members between the ladder-like non-slip members, and It consists of a net-like non-slip member integrally formed with the ladder-like non-slip member and having an inner shape and a required width that can be adapted to the outer peripheral surface, and the net-like non-slip member has ropes on both parallel strips. A rope connector locking tongue piece is provided, and the proximal end of the rope connector locking tongue piece is connected to a diagonal strip portion that intersects the parallel strip portions on both sides at a required angle. It is constructed by integrally molding a reinforcing core material into the aggregation portion, and into the parallel strip portions on both sides and the diagonal strip portion.

(Function) The anti-slip member 1 is used by being attached to the tire A as shown in the 8th to 12th figures.

As shown in the 8th to 9th figures above, each anti-slip member 1 attached to the tire A has a net-like anti-slip member 1b provided between the ladder-like anti-slip members 1a, 1a when the car is running. The ladder-like anti-slip members 1'a and 1'a can prevent shocks generated when the tire A comes into contact with the road surface between the ladder-like anti-slip members 1a and 1a, and the ladder-like anti-slip members 1'a and The above-mentioned effect is achieved by reinforcing core materials integrally molded into the parallel strip portions 1b ₁ on both sides, the tongue portion 1b ₂ for locking the rope coupling device, and the diagonal strip portion 1b ₃ of the net-shaped anti-slip member 1b, respectively. The strength of the net-like anti-slip member is increased, the durability is improved, and it is made to conform well to the outer circumferential surface of the tire, so that the net-like anti-slip member 1b is prevented from coming off from the outer circumferential surface of the tire A due to the restoring force due to self-elastic stress. Alternatively, it is possible to prevent the tire A from floating off the outer circumferential surface of the tire A during high-speed rotation, thereby allowing stable running.

(Example) Figures 1 to 17 show an example of the present invention, in which 1 is an elastic material such as rubber or synthetic resin with an inner shape that can fit the outer peripheral surface B and both side surfaces C of the tire A, and the required a ladder-shaped non-slip member 1a formed with a width; and the ladder-shaped non-slip member 1a,

Reference numerals 1c and 1c are shock-absorbing tongue pieces having a required width and a required length, which are protruded in a required number from the connecting side surfaces of the ladder-like anti-slip members 1a, 1a as needed; It is integrally formed of the same material as the ladder-shaped anti-slip member 1a and the net-shaped anti-slip member 1b.
Although it is preferable that the protruding positions of the shock absorbing tongues 1c and 1c are shifted so that they can engage with each other, the present invention is not limited thereto.

1a ₁ is a core member integrally molded within the ladder-like anti-slip member 1a, with several wires 1a ₂ and both ends of each of the wires 1a ₂ skewered in a substantially orthogonal manner. It consists of a die-cast rod-shaped rigid locking member _1a3 that is solidified into one body. Reference numerals 2 and 2 designate engagement holes with side opening notch grooves 2a and 2a formed at both ends of the ladder-like anti-slip members 1a and 1'a.

(Effects) As explained above, according to the present invention, there is provided an anti-slip member for a vehicle that is used by being attached to a tire. A ladder-like non-slip member formed with a shape and a required width, and an inner side that has at least one to several ladder-like non-slip members between the ladder-like non-slip members, and that can be adapted to the outer circumferential surface of the tire. It consists of a net-like non-slip member integrally formed with the ladder-like non-slip member having a shape and a required width, and the net-like non-slip member has tongues for locking cable coupling devices on both parallel strips thereof. A piece is provided, and the proximal end of the rope connector locking tongue piece is formed as a gathering part of the diagonal strip that intersects the parallel strip on both sides at a predetermined angle; Since the reinforcing core material is integrally molded inside the parallel strips on both sides and the diagonal strips, the impact caused by the spacing between each anti-slip member, which is a defect of conventional ladder-type anti-slip devices, can be avoided. This can be prevented by a net-like anti-slip member, and the width of the net-like anti-slip member is made approximately equal to the width of the outer peripheral surface of the tire, and at least one The net-like non-slip member is interposed with at least several ladder-like non-slip members, and the rope connector locking tongues of the parallel strips on both sides of the net-like non-slip member are locked to the cable. The material conforms well to the outer circumferential surface of the tire, and the net-like anti-slip member is easily detached from the outer circumferential surface of the tire due to the restoring force due to self-elastic stress, or the outer circumferential surface of the tire is prevented from being easily detached from the outer circumferential surface of the tire due to centrifugal force during high-speed rotation. The proximal end of the rope coupling locking tongue piece is connected to both parallel strips and diagonal strips of the net-like anti-slip member. By integrally molding reinforcing core materials into the parallel strip portions and the diagonal strip portions, the entire net-shaped anti-slip member can be reinforced, and the connection of the anti-slip members can be strengthened. Since the ladder-shaped anti-slip members located at both ends remain close to each other when attached to the tire and do not overlap at all, no overlapping protrusions are produced at both ends of the connection unlike in conventional net-type anti-slip devices. As a result, it is possible to completely eliminate the impact caused by the overlapping protrusion, reduce wear on the part, prevent early failure of the connecting part, and adjust the winding dimensions to suit the size of the tire. It has various effects, such as a wide adjustable range and the ability to be used with several types of tires.
