JP3003286U - Chain for tire with shape memory alloy - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a snow tire chain that can be completely installed and removed with a single touch even for a woman with weak power in the cold wind, and for small children. [Structure] The inner and outer side chains at both lower ends of a so-called tire chain made of rope, tape, or a chain that wraps the tire from above with the contact surface of the tire (1) sandwiched, It is characterized in that it is connected with a shape memory alloy (5) such as a spring or a spring, which is warmed and stretched in advance but contracts firmly at low temperatures.

Description

[Detailed description of the device]

[Field of Industrial Application] The present invention relates to a chain for an automobile tire on a snowy road.

[Prior Art] Conventional attachment / detachment of an automobile chain is not a one-touch operation.

[Problems to be solved by the invention] [0003] In the conventional one, a car is moved to mount a chain to wrap a tire, and many parts such as a spring, a spring, and a rubber are used on the side surface of the tire, It required many steps and required a lot of power and time.

[Means for Solving the Problems] Tire (1) A rope, tape, or chain made of metal or fiber-reinforced composite material that wraps the tire from above with the ground contacting surface The inner and outer side chains at both lower ends of the tire chain (2) are connected to each other by a shape memory alloy (5) such as a spring or a spring that contracts at a low temperature of 10 ° C or less. If you connect the outer side chains to each other with a shape memory alloy (5) that has been warmed in advance with a heater, lighter, hot water, disposable warmer, etc. and immediately cool it with cold wind, snow, cold water, etc., it will shrink immediately. By tightening the chain (2) strongly and running the car evenly, the tightening of the chain (2) will be made uniform, and after that it will always be cooled by outside cold air, so this state will be maintained. You can run on a snowy road without changing the chain. When removing the chain (2), it can be easily removed together with the chain (2) because it can be extended again by warming the shape memory alloy (5) with a heater, a lighter, hot water, a disposable warmer, etc. Of course, at the time of installation, the chain (2) with a mark in the center is fitted to the upper part of the tire, and the weight (6) is attached around the chain (2) to balance the rotation with the spring shape memory alloy (5). To do.

[Operation] Even if a woman and a small child alone expand the chain, sandwich the grounding surface of the tire (1) from above and wrap the tire (1) with the chain (2). When the chains are connected with the warmed shape memory alloy (5), the chains are cooled by cold air, snow, etc. and contract, and the chain is firmly attached to the tire (1) with one touch. To remove it, warm it up and remove it.

[Advantage of the Invention] A woman with weak strength can easily attach and detach a tire chain with a single touch even for small children.

Claims (1)

[Scope of utility model registration request] 1. A metal (1) which wraps a tire (1) from the upper side with the ground contact surface interposed therebetween. Or, if the inner and outer side chains at both lower ends of the so-called tire chain (2) of a belt-shaped rope, tape or chain made of fiber reinforced composite material are warmed, it will extend, for example at a low temperature of 10 ° C or less. A chain for snow road tires connected with a shape memory alloy (5) such as springs and springs that shrink at.
