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. 13 or Fig. 14. (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. 13 or 14) As shown in FIGS. 15 and 16, both ends 11a and 11b of 11 are locked by being inserted and engaged with the other end in an overlapping manner. 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. As the tire heats up, the parts wrapped along both sides of the tire (both sides in the circumferential direction of the tire) try to restore to the original flat state due to the self-elastic stress of the net body 11, and as a result, the tire The fit to both sides is poor, and the net main body 11
Not only is there a risk that the net may easily come off from the outer circumferential surface of the tire, but since both ends of the net main body are connected in an overlapping state, there is a large range in which the winding dimensions can be adjusted to suit the size of the tire. There were some problems, such as not being able to do it. 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. Moreover, the width of the net-like anti-slip member is made smaller than the width of the tire's outer peripheral surface (contact surface) by making the entire width into a drum shape with a constriction in the center.
Due to the restoring force due to the self-elastic stress of the net-shaped anti-skid member, when the tire comes off the outer circumferential surface and the vehicle suddenly stops, the net-shaped anti-skid member acts on each connecting portion of the net-shaped anti-skid member and the ladder-shaped anti-slip member in the tire circumferential direction. It prevents extreme fatigue due to parallel compressive force, allows a wide range of adjustment of the winding dimensions to suit the tire size, and reliably prevents spike pins from coming off due to deformation and wear and loosening. At the same time, it is an object of the present invention to provide a non-slip member for a vehicle that can reduce the thickness of the entire non-slip member as much as possible, thereby reducing the weight of the non-slip member and reducing the vibration of the vehicle caused by the non-slip member. It is. (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 a ladder-like non-slip member that has an inner shape and a required width that can be adapted to at least the outer peripheral surface of the tire between the ladder-like non-slip members. It consists of a ladder-like non-slip member and a net-like non-slip member integrally formed, and the net-like non-slip member has an overall shape of a drum with a constriction in the center,
Moreover, in the center there is a diamond-shaped hole of the required size with the long axis in the circumferential direction of the tire, and on the left, right, top and bottom of the diamond-shaped hole, the diamond-shaped hole is approximately 1/2 the size of the diamond-shaped hole and has two sides. A triangular hole is formed symmetrically, parallel to one side of each of the constricted portion and the diamond-shaped hole, and the remaining side is parallel to the net forming side edge of the ladder-shaped anti-slip member, and the ladder-shaped The anti-slip member has the tip of the spike pin slightly protruding from the ground surface of the ladder-like anti-slip member, and a protective protrusion that is flush with or slightly lower than the tip of the spike pin is provided around the spike pin. It is constructed by providing a required gap and a required width. (Function) The anti-slip member 1 is attached to the tire A as shown in the fourth to sixth figures.
It is used by attaching it to the As shown in the fourth diagram above, each anti-slip member 1 attached to the tire A is protected by the drum-shaped net-like anti-slip member 1b provided between the ladder-like anti-slip members 1a, 1a when the car is running. It is possible to prevent the shock caused by the tire A coming into contact with the road surface between the ladder-like anti-slip members 1a, 1a, and also to prevent the net-like anti-slip member 1b from coming off the outer peripheral surface of the tire A. In addition, even if a compressive force parallel to the tire circumferential direction is applied to each connecting portion of the net-shaped anti-skid member 1b and the ladder-shaped anti-skid members 1a, 1a when the vehicle suddenly stops, the net-shaped anti-slip member By easily deforming the net-like non-slip member 1b from the central constriction of the member 1b, the burden on each connecting portion is reduced, and the tip portion 2a of the spike pin 2 embedded in the ladder-like non-slip member 1a can be easily deformed. Before coming into contact with the road surface, the protective protrusion 3 provided around the spike pin 2 comes into contact with the road surface and is compressed and deformed as shown in Figure 8, and then the spike pin 2 is compressed as shown in Figure 9. Since the spike pin 2 contacts the road surface, the impact when the spike pin 2 contacts the road surface is greatly buffered, and as a result, deformation wear and loosening of the spike pin 2 is prevented, and the spike pin 2 is prevented from collapsing into the ladder type anti-slip member. 1
It is possible to prevent the vehicle from easily slipping out from inside a and to perform stable driving. (Example) Figures 1 to 12 show an example of the present invention, in which 1 is an elastic material such as rubber or synthetic resin that has an inner shape that can be adapted to the outer circumferential 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,

Either of the following types: one that is bent and molded, or one that is flat at both ends when not in use, and is bent along both sides C of the tire A only when in use. It can be anything. The net-like anti-slip member 1b is formed in the shape of a drum with a constricted part _1b1 at the center, and has a diamond shape of a required size in the center with its long axis in the circumferential direction of the outer circumferential surface B of the tire A. Approximately 1/2 of the diamond-shaped hole 1b ₂ is located on the left, right, upper and lower bottom of the hole 1b ₂ and the diamond-shaped hole 1b ₂ .

Reference numeral 4 denotes engagement holes with side opening notches 4a, 4a, which are bored at both ends of the ladder-like anti-slip member 1a. Note that the engagement holes 4, 4 may be simple holes,
Moreover, the number may be one. Reference numeral 5 denotes a connecting fitting, which is made by bending a bar into a substantially O-shape, and bending its upper end slightly horizontally or downward to form a ladder-like non-slip member attachment part 5a; The lower end is bent upward to form a connecting rope attachment part 5b, and the connecting rope attachment part 5b is caulked to the connecting rope 6 (including wire, chain, etc.) at appropriate intervals to attach the connecting fitting 5 to the connecting rope 6. It is to be fixed at appropriate intervals. The connecting fitting 5 may be of the type shown in FIG. 12a, or may be formed by bending a bar into a substantially U-shape from the center and forming the bent portion into a ladder shape, as shown in FIG. 12b. The ladder-like non-slip member mounting portion 5'a may be secured to the hole 4 of the non-slip member 1a, and the tip portion 5'b may be wrapped around the connecting rope 6 and crimped. In the case of a chain, the connecting rope attachment portion 5b of the connecting fitting 5 as shown in FIG.

Reference numeral 8 denotes a connecting hook body for connecting the connecting ropes 6, 6, 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 9 denotes a tightening device attached to one end of the connecting rope 6 located outside the tire A, and the tightening force of the connecting rope 6 can be freely adjusted, such as with a band buckle or other appropriate tightening device. Any structure may be used as long as it is possible. In summary, in the present invention, any means that can attach the anti-slip member 1 to the tire A,
The structure is not limited to this example and may be of any structure. (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-shaped non-slip member formed with a shape and a required width; and a ladder-shaped non-slip member integrated with the ladder-shaped non-slip member with an inner shape and a required width that can fit at least the outer peripheral surface of the tire between the ladder-like non-slip members. and a net-like non-slip member formed in the shape of a drum;
Moreover, in the center there is a diamond-shaped hole of the required size with the long axis in the circumferential direction of the tire, and on the left, right, top and bottom of the diamond-shaped hole, the diamond-shaped hole is approximately 1/2 the size of the diamond-shaped hole and has two sides. A triangular hole is formed symmetrically, parallel to one side of each of the constricted portion and the diamond-shaped hole, and the remaining side is parallel to the net forming side edge of the ladder-shaped anti-slip member, and the ladder-shaped The anti-slip member has the tip of the spike pin slightly protruding from the ground surface of the ladder-like anti-slip member, and a protective protrusion that is flush with or slightly lower than the tip of the spike pin is provided around the spike pin. Since it is provided with the required gap and width,
The net-like non-slip member can prevent the impact caused by the spacing between the respective non-slip members, which is a defect of the conventional ladder-type non-slip device, and the width of the net-like non-slip member can be By making the width smaller than the width of the outer circumferential surface of the tire, the width of the ladder-like non-slip member is made to fit well with the outer circumferential surface of the tire, and by fitting both ends of the ladder-like non-slip member to both sides of the tire, the net-like non-slip member This prevents the tire from easily coming off the outer peripheral surface of the tire, and the ladder-like anti-slip members located at both ends of the connection remain close to each other and do not overlap at all when attached to the tire. Unlike conventional net-type anti-slip devices, overlapping protrusions are not formed at both ends, and as a result, the impact caused by the overlapping protrusions can be completely eliminated, and wear of the parts is reduced, and the connection part is Not only can early damage be prevented, but it can also be easily attached to the tire, and the wrapping dimensions can be adjusted over a wide range according to the size of the tire, making it suitable for several types of tires. In addition to being able to be used for a variety of purposes, it is possible to continue using the device by replacing only that part with a new one, instead of being unusable due to one part being damaged like with conventional net-type anti-slip devices. Furthermore, when the vehicle is running, before the tips of the spike pins come into contact with the road surface, the protective projections provided around the spike pins come into contact with the road surface and are compressed and deformed, and then the spike pins come into contact with the road surface. The impact when the spike pin comes into contact with the road surface is greatly buffered by the protective protrusion, and as a result, deformation wear (wear due to abnormal contact with the road surface) and loosening of the spike pin are reliably prevented. The spike pin can be prevented from easily slipping out from inside the ladder type anti-slip member, and at the same time, the protective protrusion has a required gap and width between it and the spike pin. Since the spike pin is formed into a protrusion, it can be easily compressed and deformed, and the original purpose and function of the spike pin can be fully achieved without interfering with the spike pin's penetration into the road surface. As a result, the entire thickness of the anti-slip member can be made thinner, resulting in various effects such as reducing the weight of the anti-slip member and reducing the vibration of the vehicle caused by the anti-slip member.
