[Detailed description of the invention] (Field of industrial application) The present invention is a tire slip prevention device used when driving on slippery places such as snowy roads. The present invention relates to an anti-slip device having a connecting mechanism for connecting the main body.

(Prior art) Conventionally, a tire skid device configured with this type of coupling mechanism uses a coupling device as described in Utility Model Application No. 146703/1983, and the tire slip prevention device main body is This helps reduce the labor involved in connecting the inside.

The above-mentioned connection mechanism is composed of a connecting member that is attached to the main body of the anti-slip device at once, and a connected member that is attached to the other end. When the anti-slip device body is wound around the tire, the connecting member and the connected member are connected. Then, insert the insertion piece of the connecting member into the insertion hole of the connected member, and the inserted piece of the connecting member engages the engagement portion at the tip of the insertion piece with the engaging claw operated by the spring member. It was connected by engaging with.

(Problem to be solved by the invention) However, since the tire slip prevention device using the above-mentioned conventional connection mechanism uses a spring member, there is a risk that the spring member may come off due to vibrations while driving or shocks caused by some external application. This resulted in the connection member being released, resulting in poor safety.

The present invention was devised in view of the problems of the prior art, and its purpose is to engage the connected member by utilizing the elasticity of the insertion engagement piece of the connecting member itself.

The structure can be arbitrarily set, and it goes without saying that it may be used in a desired anti-slip device such as a conventionally known anti-slip device for ladder-type tires.

(Effects of the invention) Since the present invention has the above-mentioned configuration, it has the following effects.

Place the insertion engagement piece of the connecting member into the insertion hole of the connected member in an inclined shape, push it into the insertion hole against the elasticity of the engagement piece body, and when the engagement piece is located below the engagement recess. The mechanism is such that the force that resists the elasticity is released and the engagement and connection is made, and unlike in the past, a separate elastic member such as a spring member is not used. There is no problem of the member coming off, which is a problem in the prior art, and as a result, there is no risk of unexpected release of the connecting member, resulting in a high degree of safety.

Furthermore, the insertion engagement piece has a two-stage shape of a first engagement part and a second engagement part, and the insertion hole is provided with a recess for the first engagement part and a recess for the second engagement part. Fitting protrusions were provided in parallel on the mating pieces, and fitting holes that matched with the fitting protrusions were provided on the connected members so that they could be engaged and fitted at several locations, so that the vehicle could be driven in the above-mentioned connected state. The load placed on the long flat plate-like body of the engaging piece that is inserted into the
Since they are dispersed at the respective engaging portions and fitting portions, there is no risk of breakage of the engaging piece main body, and it is possible to further improve safety in addition to the above-mentioned effects.

In addition, as soon as the engagement between the connecting member and the connected member is completed, the tightening rope that has been installed across both can tighten the side edge of the anti-slip device, so there is no need to separately tighten the tightening rope. This eliminates the need for the anti-slip device and reduces the overall labor involved in installing the anti-slip device.
