Description

[Detailed Description of the Invention] [Field of Business Application] The present invention is an endless belt-like gliding material made of an elastic member made of rubber or synthetic resin, which is attached to the tire of a vehicle running on a wet and snowy road surface. This invention relates to an improvement of a side rope for binding a fastener.

[Prior art]

Conventionally, it consists of an elastic member of rubber or synthetic resin,
Tire anti-slip devices, which have an endless band shape overall, are generally made of synthetic fibers such as nylon on one side edge in the length (circumferential) direction, similar to those with ends. It has a length equal to or slightly shorter than the tire length, and has only one connecting part in the entire length, and has a bonding side rope that is connected to the tire to form an annular shape, and has a bonding side rope on the other side edge. When this anti-slip device is attached to a tire, the annular portion and the hook forming one connection portion of the side rope are left in an unconnected state. And, after attaching the anti-skid device to the tire so that the side rope is located on the inside of the tire (the side facing the center of the vehicle), and then connecting the connecting portion of the side rope, the length of the non-skid device is determined. Pull and adjust the other side edge of the anti-slip device so that the (circumferential) center is aligned with the tire circumferential center, position it in the proper position, and attach one or more rubber rings to the multiple hooks attached to the other side edge. Hang them one by one and tie them up to complete the installation. One anti-skid device is now commonly used for tires of different sizes, and therefore, depending on the size of the tire to be installed, the length (circumference) of the side rope may vary depending on the tire binding. There are cases where the circumference is shorter than the circumference of the part, and therefore, in such cases, there is a problem in that it is extremely difficult to attach and remove the anti-slip device from the tire. In addition, when removing an endless strip-shaped anti-slip device from a tire, unlike an end-shaped anti-slip device, the tire must be jacked up in advance, which is a problem.

In the specification of Japanese Patent Application No. 61-126959, the present applicant has proposed a tire slip prevention device in which a large number of net-like unit units made of elastic members of rubber or synthetic resin are connected to each other, and the overall shape is an endless belt-like net. At the time of disclosure, it was also disclosed that the side rope for bondage can be easily attached to a tire by providing a total of two connecting portions in the length (circumferential) direction and having two openings. Disclosed.

[Problem that the invention attempts to solve]

The side ropes disclosed by the present applicant having connecting openings at two locations have made it possible to perform attachment and detachment work relatively easily even when the circumferences of the bound parts of the tires differ to some extent. In the case of a tire with a wide total width (maximum width in the cross-sectional direction of the tire), even if the side rope has two connecting openings, there is still a problem that it is difficult to cover the tire with the anti-slip device when installing it. Furthermore, there is still an unresolved problem that the tire cannot be separated from the tire unless the tire is jacked up to some extent above the road surface.

It is an object of the present invention to solve the above-mentioned problems and provide a side rope for a tire anti-slip device that makes it extremely easy to install and remove even a wide tire.

[Means for solving problems]

The basic structure of the present invention is to provide a tire skid device that is provided with a side rope for binding on one side in the length direction, and that is made of an elastic member of rubber or synthetic resin with a core material and has an endless band shape as a whole. The rope is cut and split in at least three places,
In addition, each of the cutting division points can be removably connected by a connecting means.

[Effect]

With the above-described structure, the side rope for bonding of the present invention can be used for tires with a wide total width, since the entire circumference of the periphery of the anti-skid device located inside the tire is expanded by at least three connecting openings. When installing, it is no longer necessary to cover the upper half of the tire with the anti-skid device and then drop the covered anti-skid device inside the tire, making it possible to smoothly cover the lower half of the tire with the anti-skid device. I can do it again.
When removing the tire, pull out the anti-skid device from the top half of the tire to the outside of the tire, and then pull the anti-skid device from the bottom half of the tire by simply moving the car a little, making it easy to stop the tire from skidding. The tool can be removed.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an anti-slip device, which is a metal fitting for fixing a large number of net-like unit units 2 made of an elastic member of rubber or synthetic resin in the length direction with a core material of fiber cord such as nylon or Kevlar. The overall shape is an endless belt-like net. In other embodiments, the anti-slip device is, for example, disclosed in Japanese Patent Publication No. 57-12689, in which a rubber string having a single core material is repeatedly wound spirally around the circumferential direction of the tire, and adjacent rubber strings are tied together. It may be a net that is connected by a large number of fixing metal fittings at predetermined intervals to form a mesh and has an endless band-like overall shape, or it may be an endless band-like non-slip device with a different configuration.

A braided cord (braided or twisted) of synthetic fibers such as nylon or a core material such as nylon is placed on one side of the anti-slip device 1 in the length (circumferential) direction, that is, on the side that is located inside the tire when attached to the tire. A bondage side rope 4 made of a non-stretchable string made of rubber or synthetic resin is connected to the anti-slip device main body 1 by a connecting fitting 5, and this side rope 4 is connected at four points in the length (circumferential) direction. It is cut and divided at approximately equal intervals from A to D, and each cutting division point A to D is connected to a connecting means 8 consisting of an annular portion 6 formed at one cut end and a hook 7 provided at the other cut end. The openings are detachably connected to each other, and a plurality of dividing openings are formed as necessary. In other embodiments, the number of cutting division points may be three, five, or six or more, and the division lengths may be at unequal intervals. If there are less than two cutting division points, it is often difficult to cover the tire with the anti-slip device.
Also, the more there is, the easier it is to cover, but on the other hand,
It takes time to attach and detach each dividing point. A particularly preferred embodiment is 3 to 6 locations in the case of passenger car tires. The connecting means 8 is not limited to that of the above embodiment, and for example, as shown in FIG. A structure in which the parts are fitted together may also be used.

In the figure, 9 is a tire, 10 is a wheel, 11 is a tire mounting shaft, and 12 is one or more rubber rings 13 for binding after being attached to the other side of the anti-slip device, that is, the side located on the outside of the tire when attached to the tire. It is a hook for passing things over.

The procedure for attaching the endless belt-like anti-slip device 1 having the binding side rope 4 of the present invention to a tire is as follows. First, all or arbitrary dividing points A to D of the side rope 4 of the anti-slip device 1 are uncoupled to create a plurality of divided openings. Jack up tire 9. An anti-slip device is placed over the upper half of the tire 9 so that the side rope 4 is located inside the tire. Anti-slip device 1 on the lower half of tire 9
cover. The hooks 7 of the divided openings A to D of the side rope 4 are connected to the corresponding annular parts 6 on the inside of the tire to form an endless annular shape as a whole. Adjust the length (circumferential) center of the anti-slip device and the tire circumferential center by pulling on the other side. Anti-slip device 1
A first rubber ring 13 is first hung in the right angle direction on a large number of hooks 12 located in the circumferential direction on the outside of the tire, and then sequentially hung on the remaining hooks 12. Similarly, wrap the remaining rubber rings 13 around the hooks 12 one by one. Also, the anti-slip device 1 is attached to the tire 9.
The procedure for removing it from is as follows. First, the rubber rings 13 located on the outside of the tire are removed from the hook 12 one by one. The anti-slip device 1 is attached to the entire tire 9.
Move it inside. The hooks 7 and annular portions 6 of the plurality of connecting portions A to D of the side rope 4 are removed to form a plurality of divided openings. Pull out the anti-slip device from the top half of the tire to the outside of the tire. The vehicle is moved a little to rotate the tire and the entire anti-slip device 1 is removed from the tire.

〔effect〕

The side rope for binding a tire anti-skid device of the present invention is cut and divided at at least three points in the circumferential direction, and each dividing point is removably connected by a connecting means to form a plurality of divided openings as necessary. Because of this structure, it is possible to install it extremely easily without requiring much effort even on tires with a wide total tire width.In addition, when removing the tire, the trouble of jacking up the tire can be omitted, making the removal work easier. This has an extremely excellent practical effect.
