Abstract

PURPOSE:To improve tightening/locking performance and durability, and lower noise so as to make a riding feeling desirable by winding the tightening rope of a tire slip preventing device between both hooks more than the specific times, and then securing a locking fitting provided at the tip of the tightening rope engagedly to the side clip or the like of the tire slip preventing device. CONSTITUTION:Elastic material 7 such as rubber is interposed at the tip part of a tightening rope 5 to mount ladder bands circumferentially along the tire peripheral surface, and the hooks 4, 4' of side bands on both ends of each ladder band are butted at each other. The tightening rope 5 connected to one hook 4 is engagedly secured to the other hook 4' and folded, engagedly secured again to the former hook 4 and folded, and then engagedly fixed another time to the hook 4' and folded. A locking hook 9 provided at the tip of the rope 5 is engagedly secured to a side clip 3, the former hook 4 or the like to perform locking. With this multiple winding of the tightening rope 5, frictional force generated between the rope parts acts upon the wound parts in this mutually overlapped state of the tightening rope 5, so that looseness between both hook 4, 4' is hardly generated.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to the improvement of a tire anti-slip device.When attached to the outer circumferential surface of a tire, by strongly pulling both ends of the tire anti-slip device, The purpose is to prevent damage, wear, and deterioration of running performance due to loosening of the rudder, hitting the road surface due to centrifugal force of the rudder, twisting, etc.

(Prior Art) Various structures have been developed to connect both ends of a tire anti-slip device, but - for boat fishing, a rope with multiple ladders connected is used, as shown in Figure 5 as an example. 2 annular portions 2a are formed, and the annular portions 2a are drawn together and held under tension by a C-shaped hook 12, or as shown in FIG. In addition, a metal tension buckle 13 is used, and the other end of the rope 2 is fastened to it as shown in the figure, and furthermore, as shown in FIG. If a chain 15 is used, the base of the end hook 14 is fixed to one end of the end hook 14, and the end hook 14 is folded back with the chain ring 15a at the other end inserted, and the tip is attached to the chain 15.
There are known devices that are tensioned by being hooked to a hooking ring 15b attached to one end of the tube.

(Problem to be solved by the invention B) However, in the case of the one shown in FIG. Since the tire gets caught on the uneven tread surface of the tire, the frictional resistance is large, and therefore it is difficult to maintain sufficient tension.

Furthermore, in the case of the one shown in Fig. 6, the tension of the rope 2 is doubled, which is advantageous compared to the one shown in Fig. 5, but the frictional resistance of the rope 2 against the tension buckle 13, which is made of metal and has a circular cross section. Since the force is small, it has the disadvantage that it tends to loosen while driving.

Furthermore, in the case of the one in Figure 7, chain 1 is attached from the beginning.
It is almost impossible to tighten the link because the slack is less than the length of the link, so a chain hand such as a rubber ring is used along the side of the tire to elastically absorb the slack. In any of the above configurations, if the rope 2 or chain 15 becomes loose, each rudder will bulge away from the trend surface of the tire in a radial direction as the vehicle travels, and will remain on the road surface. As a result of the impact and torsion of the rudder, the rudder suffered severe wear and tear and was easily damaged, as well as high noise and vibration, making the ride uncomfortable.

(Means for Solving the Problems) Therefore, the present invention solves the various difficulties in the above-mentioned prior art, improves the tension fastening performance of the anti-slip device, eliminates the tread hitting the road surface and twisting due to loosening, and improves durability. This device improves noise and ride comfort, and specifically, in a tire skid device that is installed along the outer circumferential surface of a tire, both ends of the cut end of the tire skid device are installed along the outer circumferential surface of the tire. At the same time, locking hooks are provided oppositely to each other, and one of the hooks is locked to the other hook between the opposing hooks, and this is folded back and locked to the one hook again, and further folded back to lock the other hook. This relates to a fastening structure for a tire anti-slip device, which is formed by connecting tension ropes of sufficient length to be tensioned by folding back at least two turns or more by being hooked to a hook and folded back, and the tip of the rope is fixed at an appropriate location.

The present invention also provides a tire anti-slip device that is installed along the outer circumferential surface of a tire, in which locking hooks are provided opposite to each other at both ends of the cut end of the anti-slip device, and the hooks are connected to one of the hooks. The present invention also relates to a fastening structure for a tire slip prevention device, characterized in that a locking metal fitting is attached to the tip of a tension rope with an elastic material interposed therebetween.

(Function) After the tire slip prevention device is placed along the outer circumferential surface of the tire, the tension rope whose base end is connected to one hook at the end of the cut in the device is hooked to the hook at the end of the cut in the other device. After the rope is folded back, tensioned, and then folded again, the rope is wound two or more times around at least one hook while maintaining tension between both hooks, and then the locking metal fitting at the tip of the rope is locked to a side clip or the like of the device.

In this case, if an elastic material is interposed near the tip of the tension rope, the slack of the tension rope can be completely absorbed.

(Example) Below, the specific contents of the present invention will be explained based on the examples shown in Figs. On the other hand, the rudder 2 disposed in the cross direction connects the rudder 1 through a side chest and a bar 3, and a side hand 5 forming a rudder band has hooks 4 and 4' at both ends of the rudder band. A tension rope is connected to one hook 4 of the side band 2.

The ladder 1 is made of a wear-resistant material such as plastic rubber, and is connected to the side band 2 at equal intervals by side clips 3 attached to both ends of the ladder 1. The side hand 2 is most preferably made of a rope with little elongation, and may be made of a wire rope or a metal chain. Also, hooks 4 are attached to both ends of the side band 2.
4' is attached. The hook 4.4' is fixed to the side clip of the ladder 1 at the cut end of the device, and a portion thereof is bent into a U-shape to form a hook, and furthermore, the bent portions of the hook are opposite to each other. It is attached. The spacing between the U-shaped bent portions in hook 4.4' is preferably such that at least a portion of the ropes overlaps each other when the rope is folded back two or more times to avoid attachment. . Furthermore, the tension rope 5 has one end attached to one hook 4 of the side hand 2.
It also has a locking hook 9 at its tip, and its length is such that when the ladder band is attached to the outer circumferential surface of the tire, it can be locked by folding back at least two turns between the hooks 4 and 4'. It is necessary to set it to a sufficient level to allow it to occur.

In addition, if an elastic material 7 such as rubber is interposed at the tip of the above-mentioned tension rope 5, it will be even better.

In the above configuration, the ladder band is installed in the circumferential direction along the outer circumferential surface of the tire, and after the hooks 4 and 4' of the side bands at both ends are butted against each other, one side band is attached as shown in FIG. Tension rope 5 connected to hook 4
is attached to the other hook 4', folded back, and then attached to the original hook 4 again, folded back again, and again attached to the other hook 4'.
is attached to the side clip 3 or the original hook 4, etc., and the fastening work is completed.

Further, as shown in FIG. 4, after the tension rope 5 connected to one hook 4 is hooked to the other hook 4' and folded back, the tension rope 15 on the outward path is crossed diagonally and reversed. The tension rope 5 is hooked to the original hook 4 from the side, and the tension rope 5 that has been folded back crosses the tension rope 5 on the return route diagonally again, and is hooked to the other hook 4' again and folded back, and then the tension rope 5 is hooked to the other hook 4' and folded back. It may be fastened so as to be attached to the side clip 3 or the original flap 7 4 or the like.

(Effects of the Invention) As described above, the present invention includes hooks formed at both ends of a tire anti-slip device that is attached along the outer peripheral surface of a tire, and one end of which is connected to one of the hooks and is latched to the tip. When the tire anti-slip device having a hook is attached to the outer peripheral surface of the tire, the tension rope is long enough to be folded back and tied at least two times between the two hooks. The winding tension between both hooks 4.4 can be set to at least two windings or more, and as a result, the tension between the side hooks is sequentially doubled according to the number of windings, making it possible to strongly pull both ends of the device. When the vehicle is running, each rudder is hit by the road surface and is not twisted and worn out or damaged (almost no noise or vibration is generated. Also, the tension rope between both hooks 4 and 4' As a result of overlapping windings, the tension ropes overlap and the frictional force between the ropes acts on the windings, resulting in both hooks 4.4'
There is almost no looseness between the two.

Further, in the above tire slip prevention device, when one end is connected to one of the hooks formed at both ends of the tire slip prevention device and a ladder band having a locking hook at the tip is attached to the outer peripheral surface of the tire, the above-mentioned At least 2 between both hooks
If an elastic material is interposed at the tip of a tension rope that is long enough to be folded back and tied, it is possible to absorb the slight loosening of the tension rope placed between both hooks 4 and 4'. It can be complete.

It goes without saying that the locking structure of this anti-slip tire device can also be used for binding ladder-type treads, net-type trends, metal chains, cable chains, and the like.
