DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to improvement of a tire slip prevention device, and an object of the present invention is to simplify the installation work on a tire.

(Prior Art) Various types of ladder-type tire slip prevention devices have been proposed in the past, but in all cases, the tire slip prevention device is installed after being installed facing the tire running line on the ground. , move the vehicle and position the tire on one side of the anti-slip device, then hold the other side and place it over the tire, then connect the tip and rear end of the side band endlessly and attach it. Or, leave the vehicle stopped and place the anti-skid device over the tires, then
Generally, the front end and rear end of the sight band are connected to each other in an endless manner near the grounding point of the tire.

(Problem to be Solved by the Invention) However, in the case of the former mounting method, it is difficult to position the tire in the center of the tread width of the anti-slip device when moving the vehicle, and if proper positioning is not performed, This makes it difficult to connect the tip and rear end of the side hand, causing it to come loose while driving.

Furthermore, even in the case of the latter method of attachment, the working posture is extremely uncomfortable since the front and rear ends of the sidebands are joined at a position close to the ground, making the attachment work extremely difficult and only staining clothes. However, there were drawbacks such as the need for sufficient skill.

(Means for Solving the Problems) The present invention solves the problems of the prior art described above, and enables the installation of a tire anti-slip device easily and reliably without requiring special skill. Specifically, the tire slip prevention device attached to the tire consists of a pair of left and right side bands, and a plurality of ladders supported at equal intervals between the pair of side bands, and each The rudder is abbreviated as U to straddle the tire tread.
The present invention relates to a tire anti-slip device, which is constructed in a letter-shaped configuration, and in which at least one of the ladders near the joining end of a side band is given elasticity capable of being pressed against the sidewall surface of the tire.

In addition, as another means for press-fitting the rudder near the connecting end of the side band to the tread side surface of the tire, a pair of left and right side hands whose both ends can be connected endlessly according to the circumferential length of the tire, and A plurality of ladders configured in a substantially U-shape to straddle the tread of the tire supported at equal intervals between the side hands, and at least a ladder near the joint end of the side hand among the plurality of ladders. This invention relates to a tire anti-slip device consisting of a clip that is press-fitted onto the sidewall surface of the tire (a clip that has a resilient force and is press-fitted from above the rudder).

In addition, when installing a tire anti-slip device, in order to make it easier to confirm the position of the tip of the side hand when moving the vehicle, at least the ladder near the joining end of the side hand out of multiple ladders, or this rudder against the sidewall of the tire. The present invention relates to a tire anti-slip device in which a display bar that protrudes in the axial direction of the tire when attached to the tire is attached to a clip having a resilient force that is press-fitted from above the ladder to press the tire against the surface.

Furthermore, the present invention provides a rudder near the joining end of the sideband of the rudder configured in a substantially U-shape to straddle the tread of the tire, which is supported at equal intervals between a pair of side hands. A process of temporarily fixing the rudder to the tread, a process of moving the vehicle in the rudder wrapping direction after temporarily fixing the rudder to wrap each rudder sequentially around the tread part of the tire circumference, and fixing the tip and rear end of the side hand. The present invention also relates to a method for installing a tire anti-slip device, which comprises a step of endlessly joining.

In this case, as another means of temporarily fixing the rudder near the joint end of the side hand to the sidewall surface of the tire to the tread part, a plurality of the side hands are supported at equal intervals between the pair of side hands. When temporarily fixing the ladder near the joining end of the side band to the tread of the tire, out of the rudder configured in a substantially U-shape so as to straddle the tread of the tire, after placing the rudder over the tread of the tire, A tire slip prevention device in which a roughly U-shaped clip having elasticity is enlarged from above to hold a rudder to a tire, and the clip is removed after the tip and rear end of a side hand are endlessly connected. It also concerns how to wear it.

(Function) Press the rudder near the joining end of the side hand to the tire sidewall surface of both left and right tires to temporarily fix it to the tread.

For temporary fixing, the U-shaped rudder itself is crimped against both left and right sides of the tread by its own elastic force, or after the U-shaped rudder is placed over the tread, a substantially U-shaped elastic force is applied from above. Adjust the clip to hold the rudder against the tire.

Next, move the vehicle in the direction in which the rudder tires are wrapped.
Insert the following U-shaped ladders into the tread surface of the tire one by one, and when the first temporarily secured ladder passes the tire's grounding point and rises above the ground again, and reaches a height that is easy to work on, the vehicle is removed. stop.

Next, after the tip and rear end of the side band on the far side are joined endlessly, the tip and rear end of the side hand on the outside side of this side are similarly joined endlessly, and a clip with elasticity is used for temporary fixing. Remove this to complete the installation process.

(Embodiment) Below, the specific content of the present invention will be explained based on the embodiment shown in the figure. 1 is a side band, 5 is a pair of side hands 1.1 and 1 is a ladder supported at equal intervals between shows.

The sideband 1 is made of a rope made of wire or synthetic fiber, and has an appropriate length when attached to the tire IO to be attached, and the inner sideband (1) has a glasses loop 2 formed at one end thereof, A hook 3 that can be attached to the eyeglass loop 2 is attached to the other end.

The side bands 1 form a pair for the back side and the front side of the tire with a predetermined interval between them, and the side band 1 for the front side has a known hook between it and the hook 3 for adjusting the length of the side band 1. For tightening, the hook 3 described above is integrated with the tool 4 and interposed therebetween.

Rudders 5 are supported at equal intervals between the pair of sight hands 1.1 described above, and the ladders 5 are made of rubber, urethane, or other synthetic resin materials, and the tires 10 to be mounted
A tread surface 6 that can come into close contact with the tread surface of the tire, a rising surface 7.7 rising along the side surface of the tire, and a rising surface 7.7.
and a support part 7b at the end of the tire 10. Each ladder 5 is integrally fixed to the pair of left and right side bands 1.1 by inserting the rudder 7a through the pair of left and right side bands 1.1, and by inserting and fixing caulking members 8 at the front and rear of the through hole 7a.

On the outside of the tread surface 6 of each ladder 5 described above, uneven parts (not shown) are carved as necessary to further improve the anti-slip on the road surface, and on the inside as well, tires are installed as necessary.
Concave and convex portions (not shown) are carved to prevent friction between the O and the tread surface.

Further, the rudder 5 is molded from a relatively hard material and retains a certain degree of elasticity, and the left and right rising surfaces 7.7 centered on the tread surface 6 are pressed against the sidewall surface of the tire 10 to form a tread. Alternatively, by embedding a metal plate spring or the like (not shown) in the Ugu 5 to give it appropriate elasticity, it can be similarly pressure-bonded to the sidewall surface of the tire 10. It may be configured as follows.

Only one piece of padder 5 imparted with elasticity near the joint end of the side hand is required.

Moreover, when the rudder 5 itself is not provided with elasticity, a clip 9 shown in FIG. 4 is used.

This clip 9 has a trunk portion 9a that matches the tread surface 6 of the rudder 5.
and clamping parts 9b and 9C1 which are pressed against the axial direction of the tire 10, that is, the sidewall surface, on both sides of the tire 10 with the body part 9a as the center.

In the embodiment of the clip shown in FIG. 4, the clamping portion 9C
An indicator bar 9d that protrudes in the side surface direction of the tire 10 when mounted continuously and a mark 9e attached to the tip of the indicator bar 9d are integrally provided.

Note that this display bar may be detachably attached directly to the ladder 5 near the connecting end of the side hand.

The clip 9 is made by placing the rudder 5 near the joint end of the side hand over the tread portions of the tires of the left and right wheels at approximately the same position, and then starting from above the rudder 5 with a substantially U-shaped elastic clip. The rudder 5 is compressed by the tire l.
Press it onto the side wall surface of O and hold it temporarily.

After temporarily fixing, move the axle in the wrapping direction of the anti-slip device and wrap each side wheel rudder in turn around the tread part of the circumferential surface of the tire lO, until the first temporarily fixed rudder 5 passes the grounding point of the tire. The vehicle then rises to the ground again and stops when it reaches a height that is easy to work on. In this case display bar 9
d and mark 9e are visible from the driver's seat, making it easy to confirm the position. Next, after endlessly joining the glasses loop 2 at the tip of the side band l on the back side (on the back side of the tire) and the hook 3 on the rear end, the glasses loop 2 on the tip of the side hand l on the front outside side (on the front side of the tire) and the back After connecting the hook 3 at the end in the same way, the end 1a of the side hand is tightened by pulling the end 1a of the side hand, removing the slack through the tool 4, and using the clip 9 having elastic force for temporary fixing. If so, remove it and complete the installation process.

(Effects of the Invention) As described above, the present invention provides a tire slip prevention device to be attached to a tire, which includes a pair of left and right side bands and a tire tread supported at equal intervals between the pair of side bands. It consists of multiple rudders arranged in a roughly U-shape so that they can be straddled. After temporarily fixing the rudder near the joint end of the side hand to the tread of the left and right wheels at approximately the same position, the vehicle is placed on the rudder. The rudder is moved in the winding direction of the tire so that each rudder is wound around the tread on the circumferential surface of the tire, and then the tip and rear end of the side hand are endlessly connected. When installing, the U-shaped ladder is easy to fit along the tread surface of the tire, and the center alignment is performed automatically, making installation easy and reliable without requiring special skill. This greatly contributes to safe driving by preventing soiling of clothes and accidents occurring during or after wearing, and eliminating road surface damage.

At this time, it is especially important to temporarily fix the anti-slip devices on the tires of the left and right wheels in the position between the roads and wrap the anti-slip devices around the tires on the left and right wheels by moving the vehicle once. It has very good properties and is very quick.

In addition, if a display bar or mark that protrudes in the axial direction of the tire is attached to the resilient clip when attached to the tire, the tip position of the side hand can be confirmed when the tire slip prevention device is attached when the vehicle is moved. becomes even easier.
