Making a dynamic toy "gymnast". Board game "fantastic gymnastics" Creative project movable toy gymnast on the horizontal bar
Iron tempers steel, and steel tempers the spirit. The soul, hardened by steel, has formed the strong steel spirit of our magnificent gymnast, who performs on the crossbar. "Street Workout", like popular street workouts, captures the attention of everyone who has ever watched the performance of a turnstile. Let's try to reproduce one of them from the easiest means at hand.
The final look of the craft.
To create such a mobile toy you will need:
1. Wire with a total length of 50 cm. It can be an insulated aluminum wire, or copper wire - whatever it is.
2. Nippers.
3. Small pliers and pliers.
4. Ruler, plastic cap from the pen.
5. Sandpaper, veselok or grinder with a grinding disc.
6. Napfel round thin.
7. A small nail the thickness of wires without insulation, or a drill with a drill bit of similar thickness.
8. Stove / candle / heating pad / stove.
Work begins with the preparation of aluminum wire. It needs to be insulated. You can do this in any way possible. For example, burn the insulation: in the stove, in the burner, above the candle. If there is a stove, then simply lower the wire into the fire, and it will burn easily and quickly.
Burnt insulation is removed with pliers. Then, with wire cutters, you need to cut the wire 14 cm long. Thus, you need to cut only 3 pieces of aluminum wiring.
Black and charred wire is cleaned with sandpaper.
The ends of the segments need to be sanded more diligently: aluminum should become light and clean.
Instead of a veselka, you can use a grinder with a grinding disc for metal.
Now let's start creating holes in the pen cap with a nail and pliers.
The nail must be calcined in an oven or use the flame of a candle, electric stove, gas burner.
After that, you need to try to pierce the cap through the upper part - for the hands of the gymnast. If it doesn’t work the first time, then you need to ignite the nail again and again.
The same must be done to pierce the bottom of the cap - for the legs.
The design of the head is as follows: the extra elongated part of the cap must be removed with wire cutters. Get a head with a nose.
We proceed to the most crucial moment - assembly: the first wire is threaded through the top of the cap.
With the help of small pliers we form the arms of the turnstile.
Properly placed hands on the body:
The legs are formed in the same way. In this case, you need to pay special attention to the corner bends.
Now you need to bend your arms and bite off the excess. The length of the arm together with the elbow should be slightly longer than the torso.
The hands are attached to the horizontal bar with the help of wire cutters. First, the end of the wire must be bent, and then rounded and clamped tightly to the crossbar.
It remains to bend the feet of the athlete - and the toy is ready!
The final look of the craft.
What is attractive about this turnstile model?
1. To create a toy, it is not at all necessary to spend money: everything you need for work can be found at home.
2. Even a child can make such simplicity.
3. You can decorate the gymnast with colored paper and plasticine. A large spectrum has been created to embody the most daring fantasy.
2. Due to the simple structure, the gymnast is very agile in structure.
3. All "Street Workout" lovers can play with it, regardless of gender and age.
4. And the combination of maneuvers, dynamics of movements and gracefulness of the performed acrobatic elements can excite the heart and imagination of anyone who sees the turnstile in action.

Knowledge update.
Before you know the topic of our lesson,we'll play. Your task on my command is to solve puzzles. Having solved the puzzles, we will find out what tool we will work with and what to make. And so, we started. Well done boys. As you understand today, we will work with a jigsaw and start manufacturing dynamic toy"Gymnast".
Write down the topic of our today's lesson. Making a dynamic toy "Gymnast ».
This wonderful toy is distributed all over the world: from South America to China. Who its author is unknown, but, of course, he was a very talented person.
It consists of two long sticks, which are connected in the middle of a short one. A figurine of a gymnast is suspended on threads at the ends of long sticks. With a slight compression of the lower ends of the sticks, the figure begins to move, imitating the exercises of a gymnast on the crossbar.
These toys will go to the school playroom.
(Jig saw on the screen).
Please tell me what the jigsaw is intended for, and what parts does it consist of?
Jigsaw- This hand tool with interchangeable saw blade, designed for curved cutting of plywood and thin boards along an internal, closed contour, consists of a frame, a handle, upper and lower clamps
Now try to formulate what you need to know and be able to .
Know : jigsaw device, safety precautions when working with a jigsaw,
Be able to : install a file, cut curved surfaces according to a template, transfer a drawing through a carbon paper,
And now let's listen, the history of the development of artistic sawing has prepared a short message for usIvan.
HISTORY OF THE DEVELOPMENT OF ARTISTIC CUTTING
(1Slide) Saw-cutting is an ancient kind of arts and crafts, the traditions of which are still alive in our time. Sawing with a jigsaw is not a fashionable hobby today, it is rather a call of the heart and a wonderful way to cultivate not only patience, perseverance and accuracy, but also a sense of beauty!
Artistic sawing out of wood is one of the most common types of arts and crafts available to the general public. Saw-cutters create wonderful patterns and drawings on wood, and also make artistically designed products that adorn our everyday life (vases, caskets, watches, various coasters, etc.)
(2 slide) ANDThe history of artistic sawing originates from the second half of the 19th century, improving each time. The options for drawings, ornaments, products are as wide and varied as the master can afford.
(3 slide) Artistic sawing out of plywood has grown from openwork, slotted and house carving, which distinguishes it only by the material, plywood, and the absence of a cutter. When artistic sawing out of plywood, the edges and ribs are served only for finishing and processing with fine-grained sanding paper.
(4 slide) Currently, there are 4 main types of artistic wood carving:
Geometric;
Embossed;
sculptural;
slotted.
Artistic sawing out of plywood was formed from slotted carving.
(5 slide) The main feature of a slotted thread is the removal of the background, sawing through the workpiece.
Slotted carving has become widespread due to the fact that it is the least laborious, simple in execution technique and therefore accessible to anyone, even children.
(6 slide) From the second halfXIXcenturies, Russian and Ukrainian peasants began to move from the Central regions of the Russian Empire to the East, including Kazakhstan. After the resettlement, they founded new villages here. Nadezhdinka, Terentyevka, Verenka, and others were founded on the territory of our district. The settlers brought their culture with them, including house carving.
(7 slide) The tool with which cutting occurs is called a jigsaw. The history of the appearance and development of this instrument goes back to distant centuries and countries!
Today, the manual jigsaw is not forgotten, it is being improved and new models of jigsaws appear.
(8 slide) The first such patented tool appeared in 1876 and was called the Boule saw.
(9 slide) It looked like a stationary jigsaw with a foot drive.
(10 slide) Modern stationary jigsaw with electric motor.
(11 Slide) Volumetric products made at technology lessons.
As I already said , today in the lesson you will make a dynamic toy "Gymnast". Look at the screen.
And tell me what are the main criteria that everyone who is going to produce this or that product must rely on:
· Durability
Aesthetics
Material consumption
・Practical to use
Manufacturability
・Low labor intensity
Originality of forms
material availability
・Mass production capability
We will do the practical work in pairs, so let me divide you into pairs.
Before starting practical work, let's get acquainted with the execution order. (On the screen)

Board game"Fantastic gymnastics" (Fantastic Gymnastics) from Hasbro Gaming - a new exciting entertainment for a child or a whole group of children bottom, for example, a bottle of water, etc. It can be said with due confidence that Fantastic Gymnastics will arouse genuine interest not only among children, but also among adults!
To start the game, you first need to make a simple assembly of the horizontal bar. In the set you will find: a figure of a gymnast; crossbar, fixed on two racks; base with buttons for unwinding and jumping of the gymnast; a special rug (like a mat) on which your athlete will land; detailed instructions, including the tournament bracket. When the assembly of toy sports equipment is completed, and the gymnast is fixed on the crossbar, you can safely start the competition.
The essence of the game "Fantastic Gymnastics" is to have your gymnast make a certain number of revolutions in the air, and then land clearly on his feet, thus receiving the highest score for the completed difficult element! In order to properly spin the figure, you need to press the yellow button at a certain pace. As soon as you understand that the gymnast is ready to let go of his hands and make a dizzying jump, immediately press the red button, so the figure will immediately unhook from the crossbar! It is worth noting that it is not so easy to implement such a spectacular trick “cleanly”, and even with the maximum number of revolutions in the air. It is necessary to stock up on patience in order to develop dexterity and acquire dexterity, then the impeccable performance of an incredible gymnastic element will only be a matter of technique!
You can buy the Fantastic Gymnastics board game from the Hasbro Gaming brand at the lowest price in our online store website with delivery in Moscow, St. Petersburg and all of Russia!
Homemade children's toys have always been interesting. Every toy made for a child has the love and energy that goes into its construction. No wonder children are sometimes very careful about seemingly unsightly toys.
Currently, there are a lot of different colored and beautiful children's toys in stores, so homemade toys are very rarely made. But the hidden meaning in the self-made technical toy that is precisely the process of creating a toy, thinking, building it with your own hands with the help of a tool. Moreover, such a process takes place together with one of the parents or older brothers and sisters, especially when the children are small and cannot work with the instrument on their own, this is both a game and a learning process.
Purchased educational toys(like the "Lego" constructor) are very good, they allow you to assemble many structures, but the weak link is that everything is assembled from ready-made bricks - just fasten these bricks together and get the intended design.
In such a game, the original elements of creativity disappear - the choice of materials, processing them by hand with the help of various tools until the required shape is obtained, fastening in the necessary ways, achieving the necessary function.
Therefore, a homemade toy is a truly educational toy.
As children, we were forced to build ourselves toys and equipment for games. Many of them are undeservedly forgotten. Let's try to recall some homemade toys for boys May they bring joy to children and their parents.
Wooden reel tractor
Such a tractor is interesting for boys 3-7 years old. It is made from a spool of thread or, as we called it, a katonchik.
Indentations are carefully cut out on the wooden cheeks of the katon with a sharp knife - this is the prototype of the tread on the wheels or the hooks on the tracks. 
Such hooks allow reel tractor crawl freely on sofas and pillows. The basis of the engine is rubber. Its length should be slightly longer than the coil. The best rubber is aircraft model, good rubber can be carefully pulled out of ordinary clothing gum. This tire gives you a lot of power.
On one side, a small carnation or two is hammered into the katon. The rubber band can be hooked with one end to the carnation, or you can place a piece of a match behind the carnations - then the rubber motor is fixed exactly in the center, which gives another half a meter of travel. 
In order for the rubber to spin at a low speed, a sleeve made of laundry soap.
Its diameter should be slightly smaller than the diameter of the wheel (so as not to interfere with movement), and the thickness is about a centimeter. A hole with a diameter of 4-5 mm is made in the center, for a supporting match - a small groove. You can make a muff from bath soap - it is a little softer, you can use a candle or ski wax. The softer the material of the clutch, the stronger it slows down and, consequently, the slower the tractor goes.
Assembling and starting the tractor is shown in the video.
Such a tractor does not spoil anything and does not make any sounds. Only the child himself growls a little when he plays.
Toy "Pinocchio with a ring"
This toy is cut out of 4mm plywood with a jigsaw. First, a pattern is applied to the plywood through a copy, then it is cut out. The edges are treated with sandpaper, then everything is painted and varnished. A small hole is drilled at the end of Pinocchio's nose and a harsh thread 50-70 cm long is tied. A ring 3-7 cm in diameter is tied to the end of the thread.
The ring can also be cut out of plywood or you can find a suitable ready-made one.
Holding the Pinocchio profile in your hand, you need to throw the ring up with a jerk of the thread and put it on your nose. The smaller the diameter of the ring, the more difficult it is to do.
Several people play at once, trying to score as many effective throws as possible in a certain number of attempts.
Working model sailboat
Being on vacation near the water in the summer, you can with great pleasure engage in the manufacture and launch of small sailing boats.
To make these, it is enough to have only a sharp knife with you. A suitable piece of dry wood is taken, or, even better, pine bark, which sometimes comes across on the banks of a river or lake. The hull of the boat is cut with a knife - a flat-bottomed boat with a sharp bow and a rounded stern.
The hull is tested for lack of roll.
Then two cuts are made in the hull - one vertical in the middle of the stern for attaching the rudder and another cut with the tip of a knife right in the middle of the hull along the fibers for attaching the mast.
The mast is made of a round twig, light and durable. One end of the twig is sharpened with a spatula and hammered into a cut in the middle of the body with a knife handle. The rudder is pulled out of a flat piece of wood about the thickness of a ship's hull and about one-third the length of the hull. The rudder is also driven with a knife into a notch in the stern of the hull, and the rudder must be completely immersed in water.
The sail is also cut out of birch bark with a knife. Round holes are made at the top and bottom of the sail, with the help of which the sail is carefully pushed tightly onto the mast.
It is possible to equip one mast with several sails.
Sails can be made from plastic bottles, and the body is made of foam. You can build a frigate by equipping the ship with three masts and big amount sails. The main thing is that he does not roll over from the severity of the equipment and tolerates pitching well.
After several buildings, experience comes and the ships keep their course well and gain good speed.
If you have several sailboats, you can arrange a small regatta for speed and accuracy. It is very convenient when there is a shallow closed reservoir, where you can work out launches without fear and without loss of ships.
paper planes
A child of 5 - 7 years old is usually already easily controlled with scissors, and he is quite capable of building these schematic flying models of aircraft himself.
The best thing paper planes are obtained from postcards - they have good thick paper and suitable sizes. Planes keep their shape well and fly well inside the room. 
You can cut out models of various shapes and designs, you can test a flying wing, make two stabilizers, make wings of various sweeps. 
Each form of the model has its own flight characteristics, its own flight speed and its own stability in flight. When building a flying model, it should be taken into account that one hundred and all lines of the aircraft must be perfectly straight, that is, the paper should not be wrinkled. The folds of the papers are gently ironed with a fingernail.
The center of gravity of the model should be in the first third of the wing. The angle of attack of the hind wings should be within 15-20 degrees, it is selected experimentally and then obtained automatically. A well-gliding, slow-moving model should come out of a vertical dive with an outstretched arm and land smoothly on the floor. An airplane launched up from the floor makes a dead loop and makes a soft landing.
Gymnast on the bar
The basis of the toy is an "H"-shaped frame made of two wooden slats fastened in the middle with a bar. Two parallel threads are stretched in the upper part of the frame, threaded through the holes in the hands of the gymnast figurine in the "feet up" position.
The figurine of a gymnast is cut out of veneer or other thin material. The arms and legs of the gymnast are articulated with the body using a thin wire.
In the initial state, the gymnast hangs on the threads with his feet down, and the threads are twisted 180 degrees to the left and right of him.
If now you slightly squeeze the lower ends of the crossbar with your hand, then the threads at the top will stretch and the gymnast will do a handstand. If at this moment the ends of the crossbar are unclenched, then the gymnast, by inertia, will turn over to the other side and the threads will twist again, only in the other direction.
By changing the strength and sharpness of the pressures, you can get very interesting pirouettes of the gymnast.
Ship models with a rubber motor
Creation boat models with a rubber motor, even a very simple, already the process of creating a technique. There are already shafts, screws and brackets, there is something to think about and do.The simplest ship model is a wooden boat with a rubber engine.
The hull of the boat is cut out of a wooden plank, and a cutting is made from a suitable block or piece of foam. Next we build a rubber motor. For the operation of the screw from tin, we make a bracket with a tube for the shaft (we beat the nail) and bend the ears for fastening. The bracket can be attached with nails or small self-tapping screws.
We cut out the screw from tinned sheet, solder the axis from a paper clip in the middle and bend the propeller blades.
Then we put a bead on the axis as a bearing, insert the axis into the bracket and bend the hook.
In front of the body we hammer in a wire hook for an elastic band. The rubber motor is made from aircraft model or fishing gum. The number of rubber bands is selected empirically. In the free position, the rubber motor should sag about half the length of the rubber. The ends of the rubber can be covered with threads by inserting rope loops.
The rudder blade of the boat should be directly in the center of the propeller. The axis on which the rudder blade rests must ensure that the rudder turns at least 45 degrees, then the model can be launched in an arc.
For the convenience of planting a rubber motor, instead of a hook in the bow of the hull, you can put a nose bracket with a fixed handle.
On the rubber motor, you can build a submarine that can dive to a depth of up to a meter or even more.
In order for a submarine to dive into the water on the move, it needs depth rudders and very little positive buoyancy. Two pairs of depth rudders are also made of tin. To control buoyancy, we use flat lead weights. We strive to ensure that only the cabin of the boat is visible from the water afloat. The trim should be zero, that is, the boat should not peck down either bow or stern.
Before adjusting the buoyancy, the submarine must be painted, otherwise, after several launches, the wood will get wet and the submarine will go under water forever.
The longer the hull of a ship model with a rubber motor, the greater its power reserve. The quality of the lead screw also affects the power reserve.
boomerang frame
Being in nature, you can make a very simple boomerang in two minutes - a frame of five flat wooden slats 20-25 centimeters long. For this, the slats are intertwined according to the figure. The design is held by the bending of the rails.
The frame is taken in hand by the lower part of the central rail and thrown into vertical position forward and slightly up, and she, like a real boomerang, lies on her side and, making a circle, returns back.
If it hits a hard object, it shatters into pieces. It's cool, you can collect again.
A simple car with an electric motor
The simplest car with an electric motor has wooden frame made of plank or plywood, four wheels in pairs on two axles, no steering, direct transmission - from the engine shaft, on which a rubber tube is dressed - right on rubber wheel car.
The meaning of such a car is to feel the excitement of construction, to see the dynamics and power of the electric motor, to study the basics of electrical engineering. The wheels of the model are taken ready-made from a suitable toy, the axles are made from bicycle spokes. The axle mounting brackets are cut out of tin and fastened with self-tapping screws or screws.
The electric motor is attached with a bracket to the frame.
It would be better to fix the electric motor on a non-rigid elastic loop bracket, then the grip with the wheel will be more reliable.
The car is powered by a double wire (from any low-voltage adapter). Batteries and the stop-forward-back switch are assembled in any plastic box of suitable sizes.
You can play just by running after the car, or you can make a circular track and fix the wire in the center of the circle.
Developing the interest of the child, you can design with him the speed controller, steering, and then he himself will design cool controllable car models and disassemble your favorite car.
Cannon of two cannons
The children's cannon is assembled from 2 wooden cannons.One of the ends of the first katon is planed straight, leaving the front sight, at the second end the lower edge is cut off to the level of the middle, and a cutout is made in the upper part of the sight. This will be the barrel of the gun with the shield.
The second katon is used without modification. These will be the wheels of the cannon.
You also need a piece of rail 2 cm wide and 4-6 mm thick, about one and a half lengths of the caton. This will be a kind of emphasis and hook for the ramrod.
The most difficult part in the gun is the ramrod. Its pushing part should be round and without friction enter the barrel. Length - slightly shorter than the barrel of the gun. The back part: width - along the width of the stop, height from above 1-2mm, height from below 2-3mm, but so as not to wedge when shooting. All edges in contact with the shield of the barrel (except the top to avoid injury) must be steep so as not to jam. The length of the back is 2.5-3 cm, on the back there is a small cutout for an elastic band. Material - birch. Pine is also good, but more often falls apart when shooting.
A cannon is assembled on threads for sewing.
First, a rubber loop is tightly tied with threads with ends on both sides. Then the emphasis is tied and immediately we tie the lower caton - the wheels across, tightly fitting the threads crosswise.
We insert the ramrod and put on the back of the rubber. The gun is ready.
We shoot with peas or whatever we find. We cock the ramrod, hook it on the edge of the stop, load the pea, put it in the firing position.
Now, if you press your finger on the top of the shield, the cannon will fire.
Bow and arrows
Bow and arrows are acceptable for playing outside the city, because an arrow shot from a bow flies relatively far. This is not a sports bow, but its distant analogue for playing and training with its own shooting techniques and techniques.
The bow is made from an even piece of willow with skin or veres (juniper), which is even better. A piece of the barrel 50-100 cm long is selected with the necessary rigidity so that there is enough strength to pull the bow.
The bowstring is made of strong kapron thread. the bowstring is tied at the ends of the bow into cut grooves, and is tied in an unstretched state.
In order to pull the bowstring, one end of the bow rests on the ground, with the other hand and body they bend the bow and wind the bowstring into the groove to the required tension. Therefore, the groove for winding the bowstring should be made deeper with a channel for pulling.
The arrow is cut with a knife from a lath split off from an even piece of wood, precisely split off so that the knife is processed exactly along the fibers. Otherwise, the arrow will be impossible to craft.
In front of the arrow, a thick wooden tip is left in the form of a thickening, which is rounded off so that the arrow cannot do much harm. A shallow groove for the bowstring is cut from the back of the arrow. The shooting technique is the most common, the only thing with this design is that the grip of the arrow shank is not athletic - on the bowstring, but playful - with two fingers on the arrow shank.
A simple toy self-propelled tank with an electric motor
Approximately in the same technology as for a simple car, you can build toy self-propelled tank. It is even more interesting to play such a tank, because it can overcome significant obstacles.
Its speed is small, so it is convenient to work with a wired remote control. Simple design the tank does not provide for its turns, only forward and backward movement.
The design of a tank's transmission is much more complex than that of a car. It uses a multi-stage gearbox made of gears from toy cars. You can choose a suitable ready-made gearbox, or you can assemble a simple gearbox yourself.
First you need to pick up the gears.
The main running gear is tightly hammered or soldered onto the axle. To fasten the gears, studs of the desired diameter are selected and bitten to the desired length.
A suitable rectangular block of strong wood is taken. The position of the gear adjacent to the running gear and, accordingly, the position of the bar are tried on.
Then we work separately with the bar. In the marked place we pin the tried-on gear, then try on and pin the next one.
We press the bar with the gearbox to the running gear and fasten it to the tank frame with self-tapping screws.
When hammering a small gear onto the motor shaft, the second end of the shaft must be rested against the anvil so as not to break the engine. We press the gear of the electric motor to the gearbox and fasten it with a clamp.
We select the drive shafts and sloths of the tank from unnecessary cars.
Rollers are more of a problem. They can be made from playing plastic checkers.
We drill holes with a diameter of 2.5-3 mm in the centers of the checkers, connect the two checkers with the planes inward, thread a tight suitable piece of PVC tubing into the holes and hammer in the axis. As long as the measurements are correct, everything will fit perfectly.
We glue the caterpillars from a rubber strip from the bicycle camera, rubber lugs can be glued, or wooden ones can be sewn from matches. Caterpillars should be tightly put on the tank rollers. When scrolling the caterpillar, the drive roller can be rubbed with rosin.
Such caterpillars sometimes fall off during operation, but this can be corrected by restrictive collars on sloths. In general, full scope for modernization.
Tank superstructures can be glued from any suitable material.
If you put a separate gearbox with an electric motor on each tank track, you get a fully functional model. The axles of rollers and sloths must be replaced with separate axle shafts for each side.
The control unit will also have to be modified to be able to control two engines.
So, to make a gymnast on the crossbar, we need pieces of plywood, a jigsaw, sandpaper, a strong rope, small shoe studs and ... perhaps that's enough, we'll find the rest in the process of work.
To begin with, we will cut out two strips of 200 mm by 20 mm with a jigsaw on wood from plywood - these will be the side racks of our sports equipment. Now we need a crossbar between them, which we will make from a width of 20 mm and a length of 60 mm, any thickness can be made.
We burn out two holes from one end of the racks using a thin tip of the burner, or try to drill with a very thin drill, only carefully so that the thin racks do not split. Now, between the uprights in the lower part, we will beat the bar with thin shoe nails.
The figurine of the gymnast will be made of plywood
Next, we need the gymnast himself. We will also cut it out of plywood, having previously drawn the outline of the gymnast. In principle, you can cut out anyone: a gymnast, a bear, everything that your imagination is capable of. But in our case, we are making a gymnast. There are two drawings here, they are not much different, but the manufacturing principle is the same.
For example, in one drawing, the gymnast's torso is sawn out together with the legs, in the other, the legs were sawn out separately, as well as the arms. Which way to choose is up to you. In the hands you need to drill three holes: two in the palms and one in the forearm.
We attach the hands to the body of the gymnast with studs or thin bolts, so that they freely rotate around the body. Attach the legs in the same way if you made them separately.
First, sand all parts of the gymnast's body with sandpaper so that his figure becomes smooth and beautiful.
Now we put the gymnast between the racks and connect the double holes with a strong rope, nylon thread, you can put plastic straws from the juice on them. All our cheerful gymnast is ready. Cross it by throwing it back, and now press the lower ends of the crossbars, and the gymnast will begin to rotate.
The gymnast on the crossbar is very cheerful and. See how cool the figure of the gymnast is spinning on its crossbar. You can present a gymnast on the crossbar to your best friend, and he will surely be endlessly happy for your attention.
