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, anti-slip devices for vehicles that are attached to tires have been developed, for example, as disclosed in Japanese Patent Publication No. 57-53201, or as shown in Fig. 18 or Fig. 19.

(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 ends 11a and 11b of 11 are inserted and engaged with each other in an overlapping manner as shown in FIGS. 20 and 21, the overlapping is unavoidable. One of the shaped insertion and locking portions has a protruding shape 11c relative to the road surface, and due to friction with the road surface, this portion is prone to wear and damage more quickly than other portions, and also causes 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).
The net body 11 attempts to restore itself to its original flat state due to its self-elastic stress, and as a result, there is a risk that the net body 11 will not only become less conformable to both sides of the tire, but also become more likely to come off from the outer circumferential surface 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 parts, and eliminating impact caused by the protrusions. Moreover, the width of the net-shaped anti-slip member is made approximately equal to the width of the tire outer peripheral surface (contact surface), and at least one to several ladder-shaped anti-slip members are formed in the net-shaped anti-slip member. The rope connector locking tongue portions of the parallel strips on both sides of the non-slip member are locked to the cable, and the rope connector locking tongue portions of the both parallel strips, the rope connector locking tongue portions and the diagonal strips are By integrally molding a reinforcing core material inside each piece, the strength of the net-like anti-slip member is increased, and the restoring force due to self-elastic stress prevents the net-like anti-slip member from coming off the tire outer circumferential surface and during high-speed rotation. It is an object of the present invention to provide an anti-slip member for a vehicle, which prevents floating of the tire and at the same time allows a wide range of adjustment of the winding dimension according to the size of the tire.

(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. The reinforcing core material is integrally molded into the aggregation part, the parallel strip parts on both sides, the diagonal strip part, and the tongue part for locking the cable coupling device.

(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,
The ladder-like anti-slip members 1a, 1 have at least one to several ladder-like anti-slip members 1'a between 1a, and have an inner shape and a required width that can be adapted to the outer peripheral surface C of the tire A. This is a non-slip member constituted by a net-shaped non-slip member 1b made of the same material and integrally formed with the member 1a. 1b ₁ is the parallel strip portion on both sides of the net-like anti-slip member 1b, 1b ₂ is the tongue piece for locking the cable connector, 1b ₃ is the oblique strip portion, and 1b ₄ is the cable connector. The proximal end of the locking tongue portion _1b2 , _1b5 is a connector locking hole, and _1b6 is a reinforcing core material. The reinforcing core material _1b6 may be a metal wire such as a wire, a synthetic fiber string, a band, or any other suitable material. Further, the ladder-like anti-slip members 1a, 1'a
The rope connector locking tongue piece 1b ₂ may have both ends bent in advance to fit along both side surfaces C of the tire A, or one end may be bent in advance to fit along the inner side of the tire A. Either a curved tire or a tire with both ends flat when not in use and bent along both sides C of the tire A only when in use. good. 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-like anti-slip member 1a and the net-like 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 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 cutout grooves 2a and 2a formed at both ends of the ladder-like anti-slip members 1a and 1'a.
Note that the engaging holes 2, 2 may be simple holes, and the number thereof may be one. 3 is a connecting fitting,
Bend the bar into a roughly O-shape, bend the upper end slightly horizontally or bend it downward to form the ladder-shaped anti-slip member attachment part 3a, and then bend the lower end upward to form the rope. The cable attachment part 3b is caulked to the cable 4 (including ropes, wires, chains, etc.) at appropriate intervals, and the connecting fittings 3 are attached to the cable 4 at appropriate intervals. It is fixed. In addition, when the cable 4 is a chain, the cable attachment part 3b of the connecting fitting 3 is loosely wound around the chain and attached as shown in FIG. 13. Further, the connecting fitting may be formed of a plate material as shown in FIG. 14. Reference numerals 4a and 4a are ring portions formed at both ends of the cable 4, and may be of any type as long as they can lock a connecting hook body 5, which will be described later. Reference numeral 5 denotes a connecting hook body for connecting the cables 4, 4, and several types of hooks with different lengths are prepared according to the size of the tire A, and the one that matches the size is used. Reference numeral 6 denotes a tightening device attached to one end of the cable 4 located on the outside of the tire A, which can freely apply the tightening force of the cable 4, such as a band buckle or other suitable tightening device. Any structure may be used as long as it can be adjusted. Reference numeral 7 denotes a band, which is a tongue piece that is locked in the connector locking hole _1b5 of the cable connector locking tongue piece part _1b2 of the net-like anti-slip member 1b, as shown in FIG. 9a. This is to lock onto the locking hook 8 and prevent the net-shaped anti-slip member 1b from floating up. The hook body 8 for locking the tongue portion is made of a bar material such as metal or plastic, or a plate material, and as shown in _FIG . It may be configured to be locked to the cable 4. 9 indicates a spike.

In short, in the present invention, any means and structure may be used as long as the anti-slip member 1 can be attached to the tire A without being limited to the present embodiment.

(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 desired shape and width; and an inner side having at least one to several ladder-like non-slip members between the ladder-like non-slip members, and adapted to fit the outer peripheral 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 reinforcing core material is integrally molded within the parallel strips on both sides and the diagonal strips and the rope connector locking tongue, each anti-slip member is free from defects in conventional ladder-type anti-slip devices. It is possible to prevent the impact caused by the gap between the net-like non-slip members by making the width of the net-like non-slip member approximately equal to the width of the outer peripheral surface of the tire, and At least one or several ladder-like non-slip members are interposed in the middle part of the net-like non-slip member, and the cable connecting device locking tongues of the parallel strips on both sides of the net-like non-slip member are engaged with the cable. By stopping the net-like anti-slip member, the conformability of the net-like anti-slip member to the outer circumferential surface of the tire is improved, and the net-like anti-slip member can easily come off from the outer circumferential surface of the tire due to the restoring force due to self-elastic stress, or It can prevent the tire from easily floating off the outer circumferential surface of the tire due to centrifugal force during rotation, and the proximal end of the cable coupling locking tongue can be attached to both sides of the net-like anti-slip member. The parallel strip portion and the diagonal strip portion are integrated, and a reinforcing core material is integrally molded into the rope coupling locking tongue portion, the parallel strip portions on both sides, and the diagonal strip portion, respectively. By doing so, it is possible to reinforce the rope coupling device locking tongue portion and the entire net-like anti-slip member, and the ladder-like anti-slip members located at both ends of the connection of the anti-slip member are close to each other when attached to the tire. Since the state is maintained and the polymerization state does not occur at all, no polymerization protrusions are generated at both ends of the connection unlike in conventional net-type anti-slip devices, and as a result, the impact caused by the polymerization protrusions can be completely eliminated, and the parts It can reduce wear on the joints, prevent premature failure of the connecting parts, and also allows a wide range of adjustment of the winding dimensions according to the size of the tire, and can be used for several types of tires. I can do it, etc.
