Description

DETAILED DESCRIPTION OF THE INVENTION Chains are attached to passenger cars to prevent them from slipping when frozen, and this invention is a model devised to help people become familiar with attaching and detaching chains.

There are demonstrations of simple ways to put on and take off on TV, but although it seems simple, it is quite difficult and it is not easy to master it to the point where it is practical.

Challenge your colleagues, friends, and children to real vehicles □
Even if you give them practical training using a computer, they may seem to understand it, but they will not be able to master it. It is difficult to master this technique by following instructions and practicing in the cold wind. The process of thinking for oneself is completely ignored.

Because you just do it randomly, you won't be able to master it to the practical level.

It's not easy to put on and take off, so don't worry about the weather.

They don't want to put on and take off their clothes on a case-by-case basis, they don't want to put them on if they freeze for a while, and they don't want to take them off even if they're not needed anymore. Chains and snow tires on snow-free asphalt are not good for the road or the ride quality, but while there is a possibility of snowfall, don't use snow tires.
There are many things.

The real chain is surprisingly heavy, and unless you are fully experienced in putting it on and taking it off, it won't go smoothly.

What is the purpose of this invention?

(b) Ability to understand the mechanism of attachment and detachment indoors.

(b) Since it is a model, it is easy to carry and put on and take off, so there is no burden on the practitioner.

(c) Since you can practice putting on and taking off in a variety of ways, the process of understanding the simple to difficult ones will arouse curiosity like a quiz, so everyone from children to adults can have fun trying out the 9 magic tricks. You can easily understand the mechanism of putting on and taking off.

With a real tire and chain, it's heavy and it's a burden to try different methods, but with a model, you can try out all kinds of scenarios.

Next, let's talk about the structure, usage, and effects of this model. Although this machine is a model, the exact same operations can be performed with full-size tires, wheels, axles, chains, etc., so the word "model" will be omitted in some parts of the explanation below.

■ The wheel model is one that does not touch the ground and is removable from the axle, and the Cheno model is not fixed.

Figure 1-21 with the chain attached Figure 1-3 with the chain removed Figure 1-1 and Figure 1-4゜If you have never attached or taken it off before, the best idea is to remove it and put it back on) Easy to understand. This involves tying the back or front end of the fake chain, spreading the chain model over the tire model, and tying the other side to attach the wheel. In actual applications, it is extremely troublesome to lift the wheels and remove them.

■Next, the wheel cannot be removed in the condition (■), and the chain model (■-) is fixed to the upper surface 1-1' of the tire. Figure 2-11 Figure 2-2゜The wheels are rotatable and difficult to operate. Connect o' and o' on the back side, spread the chain all around the tire from the back side, and finally connect 0 and O at the lower part 3 on the front side to complete Y. When connecting on the back side, see Figure 9. Try to understand the key points in 4-2.

■ Parts ■-■' of the chain model are fixed on the grounding point 3-3' of the tire model. Figure 3-1゜Figure 3-21Figure 3
Since it is in contact with the ground at -3°, there is no rotation of the wheels. At this time, 1 Connect @' and 0' on the back as shown in Figure 3-4, put the inner chain over the upper part 1' of the tire, and spread it all around the tire. Combine them to create the finished product. Although this is a method often used by the general public, the idea shown in Figure 3-4 is often not clearly recognized.

■ In this case, ■ is grounded, and the tire model is fixed at the axle and the grounding point, and the chain model is also fixed to the top of the tire model as in Figure 2-1. Connect 07 and 0' as shown in Figure 4-2, cover the inner chain model over the tire model, and connect O and 0 at position 3 on the front to complete the chain. Help students understand that they are joined on the outside of tire model 2 or 4. Figure 4-19 Figure 4-2゜Now let the radius of the tire model be ``=1''.

The length of the wrapped chain should be equal to the circumference of the tire model, and should be 0' from the chain model ■' or,
■If the length of O' is equal to L from '', then the money profit △ that appears outside of 2 or 4 is 2L = 2 'π - 2π, l = π.
, Δ+=L 2'=π-2=1.14, which means that you can earn as much money as the radius.

(2) Next, in (2), instead of (2) fixing (2) - (2) to 1-1/, (2) fixing (2) to (1) - (5') so as to have linear mobility. Figure 5-12 Figure 5-21 Figure 5-3゜At this time,
It is better to attach a string to ■ and bring it to the front side, or fix it to something on the front side (such as 5.IO in Figure 10-1) while making money.

At this time, ■' can be further slid from the 1' position to the 5' position. Figure 5-42Figure 5-5゜The money gain △ at this time is L-r=-r-1=2.14, and a margin close to the diameter of the tire model can be obtained. 2 dorsal chain models
Or, connect 0' and 0' on the outside of 4, pull up ■ and ■' to the 1 and 1/ position of the tire model, cover the tire model with the chain model, and connect O and 0 at position 3. It's done.

It is a good idea to pull the string attached to ■ when pulling it up from the axle.

This sliding fixation may be achieved by shifting ■ from 1 to 1', and nine different modes are possible.

This method is so simple that it can be applied to actually attaching and detaching tires and chains by simply attaching a string to ■. In actual application, sliding accessories will of course not be used, but the idea of attaching a string to ■ is useful. When you take it off, do exactly the opposite of when you put it on. That is, remove the joints 0 and 0 on the front side of 1, place the chain model onto the axle on the back side, and remove the joints O' and O' on the back side on the outside of tire model 2 or 4.

In the relationship between a practical tire and chain, there is no sliding attachment, so when removing the actual tire/chain model, in addition to the above method, first remove the 0 and O connections in step 3, and .

When the OI is pulled up, the oI and 0/ connections are pulled up to the position of the axle 5/, and finally, ay 1'.

9 can take the form exactly as shown in Figure 7-4. From this idea, we can understand method ■.

■ Next is a variation of ■ (5) in Figure 6-1.
An example of a large slide from →(6)→(6)′→(5)′. As expected, put two strings on ■.

Once the connection between OI and OI is formed at the outer part of 2 or 4, pull this string and pull up ■ to make the operation smoother.

■ When you remove the sliding attachment, ■' becomes l',
This is an application of climbing over ■ to form the shape shown in Figure 7-4. First, a and O' are combined and slidably fixed at (5Y→(6)'. Figure 7-1゜Figure 7-21Figure 7-
37 Fig. 7-4゜ Pull up the o'0 joint part in the direction of (6)'-(5)' and the axle directions 2 and 4, and then cross over the 07 part in the order of 1→1'. Fig. 7-57 Fig. 7-6, Fig. 7-7, Fig. 7-8 o Then, cover the tire model with ■, ■, ■ and connect O and O at part 3 to complete.

■ Figure 8-1 shows three lines surrounding the grounding point of the tire model.
O' and O' are combined at the part, and this joint becomes (6) → (
It is fixed so that it can be slidably moved in the direction of 7)→(7)′→(6)′→(5)′. First, move the a connection part from (6) to (7) to (7)' to (6y).

■, ■Pull out l towards 3. When the time comes, ■゛,
■I comes up to the 3rd part. The rest is 1 Figure 7-4 according to ■
1 Figure 7-59 The chain model can be attached to the tire model in the manner shown in Figures 7-6, 7-7, and 7=8.

■ Do the same thing as ■ with a tire model fixed to the axle and grounding point and a chain model that is not fixed.

That is, first, rotate the back chain model a around the grounding point of the tire model like a donut.

Figure 9-1゜Next, connect O' and O' in 3 parts, turn it, and send the joint part of 0' and Ol back to the 3' part. 1 Figure 7-41 Figure 7-51 Figure 7 -6, Figure 7-7゜ Place part 07 on the dorsal side as shown in Figure 7-8, ■.

Cover ■ and ■, combine @ and 0 with part 3, and complete.

To remove it, remove the current reverse bond between O and 0, raise ay, bring 0' and 0' closer to 5', and change ■' to 1' →
Climb over 1 as shown in Figure 7-4, pull out the 0' and 0' joints of the inner chain to part 3, and remove.

Consideration of other specific examples Since the purpose of this model is to learn the principles, the material can be freely selected as long as it has the above functions. Models of all possible combinations, such as those made with inexpensive materials (
You can also make a large number of independent models with a model of the question) and the completed model (correct answer) in symmetrical positions on the back.

Alternatively, you can arrange them in order from easy to understand to difficult to understand, and make one or several sets.Furthermore, you can put a model of a train or car on the top of the seven soles. may be tethered.

Another idea is to make a more precise model and place the correct model in a symmetrical position (or to the right or left). In this one practice area, you can incorporate and remove all kinds of combinations, from simple to difficult, fixing with accessories, sliding fixation, etc.It is like a plastic model. is possible. Of course, one practice area may be expanded to several.

It is important to provide a quiz feature to arouse the user's curiosity by specifying (restricting) how the user puts on and takes off the item.

How to attach accessories is shown in Figure 10 on the tire model and wheel model.
-1. Figure 10-2, Figure 10-3. Figure 10-4゜Figure 10
You can add a mechanism like the example in 7-7, or you can add a mechanism like the one shown in Figure 10-5 to the axle model. One idea is to attach an adapter like the one shown in Figure 10-6 to the axle and stop the adapter from rotating.

In addition, it is necessary to provide details such as rubber-like material to tighten the slack in the chain model.
