Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is mounted along the outer edge of a tire slip stopper (hereinafter, simply referred to as a slip stopper) wound around a tire so that the side edge of the slip stopper is tightened toward the center of the tire side surface. It is related to the outside tightening member that ensures close contact with the tire.

[0002]

[Prior Art]

 Conventionally, this type of tightening member includes an outer ring 300 formed to have a diameter smaller than that formed by the outer edge 201 of the anti-skid device 200 wound around the tire 100 as shown in FIG. A nuclear ring 400 that is smaller in diameter than the outer ring 300 and is concentrically located at the center of the outer ring 300, and an arm portion that radially extends from the outer surface of the nuclear ring 400 toward the inner surface of the outer ring 300. The wire diameters (wall thicknesses) were all the same.

[0003]

[Problems to be solved by the device]

 However, the arbitrary portion 301 of the outer ring 300, which corresponds to the connecting position 700 of the both ends 202, 202 of the anti-slip device 200 wound around the tire 100, when the connecting part 700 is pulled outward by the centrifugal force during traveling, Since it is easy to swell in the direction of the connecting portion 700 (outward), it is difficult to say that the anti-slip device 200 was sufficiently adhered to the tire 100, and there was a risk that the anti-skid device 200 would slip. In particular, in the so-called butt type anti-slip device 200 (illustrated in the figure), in which both ends 202, 202 are butted, and they are joined by the connecting metal fitting 800, the above-mentioned adverse effect is likely to occur.

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 provide an outer tightening member having a partially increased tensile strength so that centrifugal force during traveling can be improved. This is to prevent outward bulging caused by force and eliminate the slippage of the anti-slip device that is wound around the tire and attached.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the technical means of the present invention is to construct an arm portion at an arbitrary position into a substantially V-shaped front face that expands from the core ring to the outer ring.

Further, one or a plurality of arm portions may be added between the arm portions at arbitrary positions.

[0007]

[Action]

 By the above technical means, the tensile strength in the vicinity of the substantially V-shaped arm portion provided on the front is increased, and the V-shaped arm is attached to the locking hook at the outer edge corresponding to the both end connection portion of the slip stopper wound around the tire. When the circumferential part of the outer ring located above the joint is locked and attached, the V-shaped arm is located below the connecting part, and even if the connecting part is pulled outward by the eccentric force during traveling. Even if it does, the circumferential portion of the outer ring located below the connecting portion is unlikely to bulge outward.

Further, when one or a plurality of arm portions are added between the arm portions at arbitrary positions, the tensile strength at the added portions is increased and the outward bulging of the outer ring is prevented.

【Example】

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

The outer tightening member A is entirely formed of elastic rubber or the like, and is attached along the outer edges 4 of a desired tire slip stopper C wound around the tire B to provide the above-mentioned slip stopper. The outer side of C (outer edge 4 ...) is tightened toward the center of the side surface of the tire B so as to be in close contact with the tire B. The tightening member A according to claim 1 in FIGS. An outer ring 1 formed to have a diameter smaller than that formed by the outer edges 4 of the anti-slip device C wound around and a center of the outer ring 1 having a diameter smaller than the outer ring 1. And a core ring 2 that is concentrically positioned, and an arm portion 3 that extends from the outer surface of the core ring 2 toward the inner surface of the outer ring 1. It should be noted that the illustrated example is merely an example, and the present invention is not limited thereto. For example, the ratio of the diameter of the outer ring 1 and the core ring 2 or the number of the arm portions 3 can be arbitrarily set.

The arm portion 3 is formed by radially extending a plurality of arms from the outer surface of the nuclear ring 2 toward the inner surface of the outer ring 1 at equal intervals, and most of the arm portions 3b, 3c ... In addition to being formed in a straight rod shape (wire diameter), an arbitrary arm portion 3a is formed in a substantially V-shaped plane that expands from the outer surface of the nuclear ring 2 toward the inner surface of the outer ring 1. Therefore, the space between the arm portions 3b and 3h located on both sides of the V-shaped arm portion 3a is subdivided by the provision of the arm portion 3a. The portion 1a) has improved tensile strength, and in the present embodiment, the other arm portions 3b ... Have substantially the same thickness (wire diameter) as the outer ring 1 and the core ring 2, and the V-shaped arm portion 3a is formed. Since the other arm portions 3b, 3c ..., The outer ring 1 and the core ring 2 are formed to be thicker (the wire diameter is thicker), the tensile strength is further improved. The above example is only one example, and the arm portion 3a may have the same thickness as the other arm portions 3b, 3c ...

Further, only a part of the circumference of the outer ring 1, for example, the circumference part 1a extending between the front ends 3a 'and 3a' of the substantially V-shaped arm part 3a shown in the figure, and the other circumference part 1b. Alternatively, the tensile strength in the vicinity of the circumferential portion 1a (thickness portion) may be further increased by forming it to be thicker (the wire diameter is thicker) than the nuclear ring 2.

The slip stopper C shown in the figure is a conventionally well-known net-type slip stopper, and is provided with locking hooks 5 on the outer edge 4 of the net body c, but this is merely an example. Other net shapes may be shown, and although not shown, a so-called ladder-type non-slip device may be used.

Here, the mounting method of the tightening member A will be described. First, the slip stopper C is wound around the outer periphery of the tire B, and the end surfaces of both ends c and c ′ thereof are butted and connected to each other to form an outer edge. 4 are positioned on the side surface of the tire B, and the outer ring 1 of the tightening member A is extended and locked along the locking hooks 5 provided on the outer edge 4 to a desired extent. At this time, the circumferential portion (thickness portion) 1a on the V-shaped arm portion 3a is attached to the engaging hooks 5a of the outer edges 4a and 4b corresponding to the connecting portions D of the both ends c and c'of the slip stopper C. 5b is locked and attached, and the V-shaped arm portion 3a is positioned below the connecting portion D. Therefore, when the connecting portion D is pulled outward by the centrifugal force during traveling, the circumferential portion 1a of the outer ring 1 located below the connecting portion D has a flat V-shaped arm portion 3a. As a result, it is difficult to swell outward, and the pulling force is sufficiently resisted.

Next, in FIG. 3, one or a plurality of arm portions between the arm portions 3b and 3h at arbitrary positions, in this embodiment, two straight rod-shaped arm portions 3i and 3j are added. The tightening member A described above is shown, and by adopting this configuration, the arm portions 3b and 3h are subdivided to improve the tensile strength of the circumferential portion 1a of the outer ring 1. Further, in the illustrated example, the thicknesses of the arm portions 3a, 3b ... 3j are all substantially the same shape (same wire diameter), but the invention is not limited to this and the arm portions 3a, 3i near the circumferential portion 1a are not limited thereto. , 3j and the like may be formed to be thicker (the wire diameter is thicker) than the other arm portions 3c and the like, which can be appropriately changed.

Since other configurations, mounting methods and the like are the same as those of the tightening member A in claim 1, the same portions are denoted by the same reference numerals and the description thereof will be omitted.

As described above, the tightening member A according to claims 1 and 2 has been described in detail above. As a result, the clasp member C, which is wound around the tire B, is provided below the connecting portion D of both ends c and c ′ of the slip stopper C. A structure for improving the tensile strength of the circumferential portion 1a of the outer ring 1 which is stopped and positioned, that is, in the present embodiment, one arm portion 3 having a desired shape is formed so as to subdivide between the arm portions 3b and 3h. Alternatively, it is sufficient that the tensile strength of the circumference of the outer ring 1 can be partially improved by straddling a plurality of them, and changes and the like within the scope of the present invention are free.

[Effect of the device]

 The present invention relates to a fastening member in which an outer ring and a nuclear ring having a smaller diameter than the outer ring are connected by a plurality of arms, and an arm at an arbitrary position is directed from the nuclear ring to the outer ring. Since it has a substantially V-shaped front surface that expands, the tensile strength in the vicinity of the V-shaped arm is improved. Therefore, when the anti-slip device wound around the tire is attached to the outer edge, the outer edge of the outer ring on the V-shaped arm that corresponds to both ends of the anti-slip device wound around the tire is joined. If you attach it by locking it with the locking hook of the above, the circumference part with high tensile strength will be located under the above connecting part, and even if the connecting part of the anti-slip device is pulled outward by the centrifugal force during running. Even if this is the case, the circumferential portion located below the connecting portion is unlikely to bulge outwards and can sufficiently withstand the above-mentioned pulling, so there is no risk of causing slippage of the anti-slip device attached to the tire. It is possible to eliminate the conventional problems and improve the safety when traveling on snowy roads.

Further, when one or a plurality of arm parts are added between the arm parts at any place, the tensile strength at the added part is increased and the outer ring is prevented from bulging outward, which is the same as above. The effect is obtained.
