Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tire anti-slip device, and more particularly to a non-metallic tire anti-slip device that suppresses eccentricity of a net-like anti-slip member attached to a tire.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, non-metallic tire slip prevention devices made of rubber or the like are shown in FIGS. The tire anti-slip device shown in FIG. 2 attaches caulking brackets 22 at predetermined intervals in the longitudinal direction to the end portions in the width direction corresponding to the inside of the tires of the net-like anti-slip member 21 and fastens them to the caulking brackets 22. The non-extension rope 23 is inserted.
[0003]
In this way, the anti-slip device 21 is firmly held on the tire T by attaching the net-like anti-slip member 21 to the tire T with the non-extension rope 23 via the caulking fitting 22 as shown in FIG.
[0004]
However, as the speed of the vehicle increases, a large centrifugal force acts on the net-like anti-slip member 21, so that the anti-slip member 21 is lifted from the tire T, and the anti-slip member 21 lifted up on the ground is hit against the road surface. . Therefore, when the tire anti-skid device is attached, the caulking metal fitting 22 is arranged on the non-extendable rope 23 substantially equally in the longitudinal direction (corresponding to the tire circumferential direction) to hold the anti-slip member 21 uniformly. The non-extension rope 23 side of the caulking metal fitting 22 is gradually displaced greatly, and the holding of the anti-slip member 21 becomes uneven. As a result, the anti-slip member 21 is held eccentrically in the tire width direction, and the anti-slip It may adversely affect the grip performance of the device.
[0005]
On the other hand, in the tire anti-slip device of FIG. 3, the metal fitting 24 for caulking at a predetermined interval at the end in the width direction (on the opposite side to the end in the width direction in FIG. 2 ) corresponding to the tire mounting outside of the net-like anti-slip member 21. Are attached to the hooks 26 that are engaged with the portions of the non-extensible rope 25 between the caulking fittings 24. Thus, those using the caulking metal fitting 24 and the non-extension rope 25 have the same problem as described above, and the improvement thereof has been demanded.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a tire anti-skid device capable of suppressing eccentricity of a net-like anti-slip member and suppressing a decrease in grip performance.
[0007]
[Means for Solving the Problems]
In the tire anti-slip device of the present invention, a net-like anti-slip member is composed of a plurality of net bodies, and the net-like anti-slip member is arranged in the longitudinal direction of the net-like anti-slip member at the end in the width direction corresponding to the tire mounting inside of each net body. In the tire slip prevention device in which the locking pieces are attached at predetermined intervals and the fastening pieces are engaged with the non-extending rope for fastening, the distance between the locking pieces between the net bodies is the longest between the locking pieces. A tube member for restricting the movement of the locking piece is fitted only to the non-extendable rope portion .
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
[0018]
Figure 1 is an example of a tire antiskid apparatus of the present invention shows, the tire antiskid device D2 is in the state of being attached to the tire T. This tire slip prevention device D2 has a slip prevention member 1 in which a core material such as a tire cord is covered with rubber or synthetic resin, is knitted into a net shape, and has a stitch structure continuous in the longitudinal direction (tire circumferential direction). ing. Net-like slip member 1 is composed of a plurality of net member 1X, caulking fittings at predetermined intervals in the longitudinal direction in the width direction end portion 1X _a corresponding to the tire inner side of each net member 1X (locking pieces) 2 mounting, Ru engage Tei a non-extendable ropes 3 for fastening these to the caulking fitting 2. Both end portions of the non-extendable ropes 3 is formed on the ring portion 3a, the ring portion 3a is in a disengageably relative fastener 4 provided in the end portion 1X _a side of the stop member 1 slip.
[0019]
In this way, the tire anti-skid device D2 in which the net-like anti-slip member 1 has a divided structure, when mounted on the tire T, lifts the vehicle body with a jack to float the tire T, or expands the anti-slip member 1 There is no need to move the tire T upward, and the road surface contact portion can be removed and attached to the tire T of the vehicle as it is.
[0020]
At that time, when the road surface grounding portion is removed, the distance between the caulking brackets 2 becomes the longest between the net bodies 1X, and when a large centrifugal force is applied during travel, the caulking brackets 2Y at the portion reduce the distance. The easiest to move in the direction. Therefore, in the tire slip preventing device D2, the tube member 5 for restricting the movement of the caulking metal fitting 2 is mounted on the non-extension rope portion 3b between the both caulking metal fittings 2Y.
[0021]
Although it is preferred to attach the tube member 5 to a non-extended rope portion between the caulking fitting 2, in the tire antiskid device D2 in which the slip member 1 of net-like split structure, between at least net member 1X with What is necessary is just to provide the tube member 5 in the non-extension rope part 3b between the caulking metal fittings 2Y where the distance between the caulking metal fittings becomes the longest.
With this configuration, a large centrifugal force acts as the speed increases, and even if the net-like anti-slip member 1 is lifted from the tire T and the anti-slip member 1 lifted up on the ground is struck against the road surface, it is used for caulking. The non-extension rope 3 side of the metal fitting 2Y does not shift. Accordingly, since the interval between the caulking fittings 2Y on the non-extendable rope 3 can be kept constant at all times, the net-like anti-slip member 1 is difficult to be eccentric in the tire width direction, which adversely affects the grip performance of the anti-slip device. There is nothing.
[0028]
In the present invention, the tube member 5 may be made of any material as long as the movement of the caulking metal fitting 2 can be restricted, and is not particularly limited. For example, synthetic resin, aluminum, hard rubber and the like can be preferably used .
[0034]
【The invention's effect】
Tire antiskid device of the present invention, among the engaging piece mounted at predetermined intervals on the end of the net-like slip member comprised of a plurality of net member, and most engaging pieces distance between net member Since the tube member that restricts the movement of the locking piece is attached to the portion of the non-extendable rope between the locking pieces that becomes long, the eccentricity of the net-like non-slip member can be suppressed and the decrease in grip performance can be suppressed.
