Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tightening ring for a tire anti-slip device, which is attached to an outer peripheral surface of a tire and is fastened toward the center of the tire by engaging with an outer edge of the anti-slip device for a tire to improve the adhesion to the tire.

[0002]

[Prior Art]

 Conventionally, the tightening ring of the anti-slip device for tires has an outer ring formed to have a smaller diameter than the outer edge of the anti-slip device, and a smaller diameter than the outer ring through a connecting rod at the inner center of the outer ring. Some have a double annular clamping ring with a ring-shaped core ring, or only one elastic ring of smaller diameter than the outer edge of the cleat.

[0003]

[Problems to be solved by the device]

 However, the double annular tightening ring consisting of the outer ring and the core ring as described above is extremely strong against pulling (extension) when attached to and detached from the anti-skid device for tires, and requires excessive labor. In addition, in order to improve the tightening force, a desired tightening jig (a tool arranged at the center position of the tightening ring to tighten the ring toward the center) may be attached to the core ring. However, when it was tightened with the jig, the nuclear ring partially deflected and was not even, and it could not be tightened into a balanced shape. On the other hand, with the tightening ring consisting of only one elastic ring, the tightening force was weaker than that of the double ring type, and normally three hooks were used, and the mounting work was troublesome. Further, since this type of tightening ring does not have a jig engaging portion, it is impossible to use the above-mentioned tightening jig and it is practically impossible to use.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to easily attach and detach the anti-skid device to the outer edge of the tire, and The purpose of the present invention is to provide a tightening ring for a slip stopper for a tire, which can provide a strong and reliable tightening force with a desired tightening jig and can be tightened more evenly and in a well-balanced manner.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the technical means of the present invention include an outer ring that is locked along the outer edge of a non-slip device for a tire mounted on the outer peripheral surface of a tire, and an inner ring from the inner wall surface of the outer ring. A desired number of the connecting arms are individually extended toward each other and are connected to a desired tightening jig arranged at the center of the side surface of the tire.

[0006]

[Action]

 By the above-mentioned technical means, a force that resists the pulling of the outer ring by the conventional nuclear ring is not generated, and a desired tightening jig is connected to the connecting arm extending toward the center of the ring. The arm is tightened toward the center of the tire.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, A indicates a tightening ring, and the tightening ring A is composed of an outer ring 1 and a desired number of connecting arms 2 ..., A tire slip stopper B wound around a tire C. It is locked to a hook 4 fixed to the outer edge b'of the same, and is tightened with the desired tightening jig 3 toward the center of the side surface of the tire C.

The outer ring 1 is made of, for example, an elastic material such as rubber, and is formed to have a diameter smaller than the diameter of the outer edge b ′ of the slip stopper B when wound around the tire C.

The connecting arms 2 are made of, for example, an elastic material such as rubber like the outer ring 1, and are individually spaced at equal intervals in the circumferential direction from the inner wall surface 1 a of the outer ring 1 toward the inner side (center). The desired number, for example, four in a diagonal line as shown in the figure, are each integrally formed in a substantially trapezoidal plane shape.

The tightening jig 3 is arranged at the center position of the side surface of the tire C, and when the connecting arms 2 are locked, the tightening jig 3 is not particularly limited in its shape and structure as long as it is pulled toward the center of the ring. For example, in the illustrated octagonal shape, four locking portions 3a are erected on opposite sides of each side, and the tip ends of the extended connecting arms 2 ... They are locked to the facing locking portions 3a, respectively, and pulled toward the center of the ring. Needless to say, the locking portions 3a are provided in the number corresponding to the number of the connecting arms 2 of the tightening ring A.

The tire anti-slip device B shown in the drawing is a conventionally known net-type anti-slip device, which is provided with hooks 4 ... on the outer edge b ′ of the net body b. Only one example is shown, and other net shapes may be used, and although not shown, so-called ladder-type non-slip devices may also be used.

Therefore, the tire slip stopper B is wound around the outer periphery of the tire C, the both ends are connected to position the outer edge b ′ on the side surface of the tire C, and the latch provided on the outer edge b ′. The outer ring 1 of the tightening ring A is locked along the hooks 4 so that the tire slip stopper B is accurately set on the tire C and preliminarily tightened.

Then, after that, each connecting arm 2 of the tightening ring A is pulled (extended) toward the corresponding locking portion 3a of the corresponding tightening jig 3 by a desired extension tool D as shown in FIG. By retaining the ring A in a tensioned state by evenly retaining the respective retaining portions 3a, the outer edge b'is tightened inward (center) and the slip stopper B is attached to the tire. Place it in close contact with C. The extension tool D is not limited to the shape shown in the figure and may be any shape.

The connecting arm 2 described above is merely an example, and may be configured as shown in FIG. 4, for example, (a) a substantially triangular shape in a plane, (b) a fastening jig locking at the tip. With a locking hole 5 for use, (c) The locking hole 5'may have any shape such as a laterally wide elliptical shape, and has a structure that can be connected to a desired fastening portion of a fastening jig. Any modification is possible within the scope of the present invention, and particularly in the case of the connecting arm 2 shown in (b) and (c) above, when the extension tool D pulls it toward the tightening jig 3. , The hooking arm d of the extension tool D is hooked to the inside of the connecting arm 2 and pulled, and the locking hole 5 or 5 ′ at the tip end is locked in the locking portion 3 a of the tightening jig 3 because it is in a free state. It is convenient to use and has a great practical value.

Further, the material of the tightening ring A is not limited to the one made entirely of rubber as in the above embodiment, but may be synthetic resin or other elastic material such as a spring. A part (the outer ring 1 or the connecting arm 2) or the whole (the outer ring 1 and the connecting arm 2) of the tightening ring A may be made of a non-stretchable material such as a wire, a rope or a string. Even when the non-stretchable material is used, the non-stretchable material may be covered with rubber or the like. In addition, Table 1 shows examples of proper use. The connecting arm 2 is divided into a vertical rod 2a and a horizontal rod 2b.

[0017]

[Table 1]

Further, when the entire tightening ring A, that is, the outer ring 1 and the connecting arm 2 is made of a non-stretchable material as described above, tightening of the locking portion 3a fixed type as in the above embodiment Move the tightening ring 1 toward the center of the tire, not with the jig 3, but with a type of tightening jig that pulls the ring 1 by moving the locking part by a desired operation (for example, Japanese Patent Application No. 2-130655). A type that has a configuration in which it is gradually pulled and tightened by the desired operation shall be used. The outer ring 1 in this case has a diameter slightly larger than the outer edge b ′ diameter of the tire slip stopper B. Further, the tightening jig of the above-mentioned type (Japanese Patent Application No. 2-130655 etc.) may be used in place of the illustrated tightening jig 3 in which the outer ring 1 and the connecting arm 2 are made of non-stretchable material. Needless to say, the locking part is optional, such as one hook and two hooks.

[Effect of the device]

 The present invention is directed to an outer ring that is fitted along the outer edge of a tire anti-slip device that is mounted on the outer peripheral surface of a tire, and a desired number of individual members that extend inward from the inner wall surface of the outer ring. Since it is a tightening ring for a tire anti-slip device that is composed of a connecting arm of a desired shape that is connected to a desired tightening jig arranged in the center position, it is similar to a conventional double annular tightening ring. A force that resists the pulling of the outer ring by the nuclear ring does not occur easily, that is, the outer ring can be attached to and detached from the side edge of the tire anti-skid device without undue labor, By connecting a desired tightening jig to the extended connecting arm and tightening the connecting arm toward the tire center, a strong and reliable tightening force can be obtained, which is very useful and highly practical. ..

Further, since a desired tightening jig is connected and tightened to the connecting arms individually provided on the outer ring, there is no bending portion like the conventional core ring, and the tightening is even and balanced. be able to.
