There are bicycles and kickboards that can be moved forward without human power.

Bicycles are a means of transportation with a long history and can be speeded up without much effort, and they can be ride with just a little learning regardless of the conditions of the road. In addition, it is recommended that you exercise without wasting any energy.

Such a bicycle also has many disadvantages. First, as a means of exercise is not much lacking in the effect of walking, as well as prolonged riding the prostate gland may damage the health and cause hemorrhoids. In addition, the two wheels were dangerous and difficult for beginners to ride, and it was especially difficult to climb hills.

Kickboards are mainly children's play equipment, which is one-footed, moving forward with a lot of energy, and it is not suitable for adults to ride. In addition, it was suggested that the above-mentioned kickboard to get the driving force by rotating the pedal, but this is no different from the principle of the existing bicycle, and the method of propelling by stepping up and down the footboard has also been proposed, but it has not been put to practical use.

In the present invention to solve the above problems,

The moving means of the present invention can be easily and safely used by anyone who can walk without a separate technology as a three-wheel, it is possible to move forward by generating power by weight only by the operation of walking upright, rather it is not difficult to carry the load or go uphill The purpose is to provide a means of movement that will be more powerful when climbing.

In addition, the movement of walking, but can achieve a sufficient speed, no matter how many ride side effects, and the purpose of providing a new form of transportation that can see the same exercise effect as walking.

In order to achieve the above object, an inclined surface was used in the present invention. A pair of scaffolds equipped with rollable rollers are installed on the guide rails that make up the slope, and when they are stepped on, the pairs of scaffolds are rolled down by weight to perform relative movements alternately up and down. The direction of the movement of the present invention is advanced by connecting the direction by the roller provided vertically and adding a rack gear to the rear part of the roller scaffold, and the rack gear rotates a series of gears to transmit the rotational power to the wheels. Will be done.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 is a front view and a top view showing a state of use of the three-wheel scooter according to the invention, Figure 3 is a perspective view of the guide rail and the gearbox.

The guide rail will be described first, so that assembly and disassembly may be possible in the process of implementation, but in this drawing, the guide rail 40 and the gear box 41 are integrally represented. The guide rail portion forms an inclined surface, and the gearbox includes a part of the rear wheel shaft 14 to surround and protect the gear, as well as being supported by the rear wheel shaft to move up and down about the shaft, and the first and second gear shafts 53 It is also coupled to the outer wall of the gearbox is to serve to support the gear shaft.

The guide rail and the gearbox are moved up and down by the height adjusting device 60 supporting the front of the guide rail. At this time, the guide rail and the gearbox are moved about the rear wheel shaft 14, and the gear is smoothly operated without changing the phase of the gear. will be.

In addition, when the roller gear roller scaffold connected to the scaffold is lowered to go back to the rear, the gearbox rear is provided with two rack gear access holes (44).

The guide rail is a hollow double plate, and the lower part is a flat rolling plate supporting the roller scaffold which will be described later, and the wheel can be rolled. The upper plate has a rectangular opening 42 vertically up and down to allow the scaffold to reciprocate. Prepared side by side. The depth of the guide rail is higher than the diameter of the roller wheels to accommodate the roller wheels and smoothly roll the wheels in the guide rails. The width of the footrest reciprocating section covers the roller wheels and a part of the bottom plate of the footrest so that the footrest is upward. It should be avoided to escape (Fig. 5c).

Figure 4 is another embodiment when the gear box is not installed by using the power transmission device according to another embodiment without using the gear.

Figure 5 shows the roller scaffold to be rolled on the inclined guide rail, the roller scaffold 30 is composed of the upper plate 31 and the lower plate 32, the lower plate has four roller wheels 34 in front and rear Batch mounted. It is important to select a wheel of the appropriate size because the roller wheel 34 should roll as small as possible friction coefficient on the inclined surface. If too large, it is not suitable for the application and if it is too small, the coefficient of friction becomes large, and according to the present invention, it may be desirable to be similar to or slightly smaller than the wheel of the roller blade. In addition, the lower plate is inclined because it is parallel to the guide rail, so the upper plate on which the foot is placed is made as horizontal as possible to reduce the fatigue of the occupant. It is desirable that the angle between the top plate and the bottom plate of the roller scaffold is approximately 15 degrees. That is, when the inclination of the guide rail is 15 degrees means that the upper plate 31 is to be horizontal, which is to control the inclination of the guide rail in the present invention, but in general, when the inclination is 15 degrees, it is not too difficult This is because the state will be comfortable to use mainly.

In FIG. 6, the left and right roller scaffolds 30 are connected to the wires 36, and the rollers 37 are vertically provided at the upper ends of the guide rails so that the direction of the wire tips is 180 degrees. As described above, the left and right roller scaffolds connected by a wire become relative movements in which one roller scaffold goes down, and the other roller scaffold rises, so that the step of stepping on the scaffold alternately causes walking.

In summary, the pair of roller scaffold 30 having the roller 34 mounted on the guide rail 40 constituting the inclined surface is connected to the wire 36 to always move relative to each other. If a person stands on the rollers of the step on the top of the step down and the bottom of the step is to go up and repeat the motion is going to be walking like climbing a little slope.

If a person climbs on the roller scaffold as described above, the scaffold may momentarily slip and lose the center of the body and fall down. However, in the present invention, the power sliding device by the weight on the inclined surface as described above will rotate the wheels by using the power transmission device to move the moving mechanism in the completed device according to the present invention stepped on the footrest of the bicycle It is as safe as stepping on a pedal.

6 and 7 are diagrams showing the coupling state of the scaffold, guide rail and the gear showing one power transmission structure for transmitting the force of the scaffold to the wheel shaft.

The bottom plate of the roller scaffold of FIG. 5 is elongated to add a rack gear 33 so that the gear is formed under the rack gear 33. The rack gear 33 is a first gear 51 provided in parallel with the rear wheel shaft 14. Rotated). The first gear transmits a counterclockwise force to the coaxial second gear 52 when the scaffold is lowered, that is, when the rack gear goes backward, and on the contrary, when the rack gear is raised, i.e., rotates clockwise. Will be idle. In other words, the first gear to the left and right of the second gear is a one-way gear that transmits force only counterclockwise.

Since the second gear, which receives the rotational force from the first gear, rotates in engagement with the shaft gear 50, the rotation direction of the shaft gear and the shaft becomes clockwise opposite to the second gear. Therefore, the sliding force carried by the weight on the roller scaffold is transmitted to the wheel shaft 14 through the rack gear, the first gear, the second gear, the rear wheel shaft gear, and the wheel rotates clockwise so that the moving mechanism moves forward.

The sliding force (F = m * g * sinθ) on the inclined surface is larger and faster as the inclination increases, so that the occupant may change the inclination of the guide rail when he / she wants to run fast or requires a large force while driving the vehicle. It should be easy to adjust as needed.

12 is an exploded perspective view, a front view, and a top view of the height adjusting device 60 which supports the front part of the guide rail and increases the inclination to increase the height and decreases the inclination to decrease.

Two square columns 61 and 62 or cylinders are provided, one of which is inserted into the other and has a size that allows flow. Pin holes 65 are formed at regular intervals so that one side of the pillar 62 entering the inside is arranged up and down in a straight line, and the upper end of the inner pillar is blocked. One pinhole 66 is provided on one side of the outer pillar 61 so as to coincide with the uppermost pin hole of the inner pillar so that the two pillars can be fixed by inserting the inner pillar and inserting the pin. ) Is coupled to one of the inner pin holes 65 and the fixing pin 64 to fix the inner pillar.

In addition, the length is longer than the sum of the length of the two pillars and the diameter is provided with a compression spring (63) that can enter the inside of the inner pillar is inserted into the spring to the inner pillar and then inserted into the outer pillar and fixed pin ( 64) to fix the two pillars.

By providing two height adjusting devices provided as described above, the fixing pins are spaced 20 to 30 cm apart so as to be horizontal to face each other, and the lower part thereof is fixed to the intermediate frame 12 of the vehicle body (b of FIG. 12).

The two fixing pins 64 facing each other are accommodated in the pin holder 67 and further provided with a spring 70 for pushing the fixing pins to push the fixing pins out. In addition, the inner ends of the two fixing pins are fixedly connected by one wire 69 and connected to another wire in the middle of the wires, and pulled in one direction, so that both fixing pins are equally pulled from the inner pillar. The pin will come off. At this time, the inner pillar, which is under the force to rise by the spring, is raised up. The rollers 71 and 72 are provided to smoothly pull the fixing pin in the pin holder. In addition, the wire 69 for pulling the fixing pin is connected to the lever 68 provided in the handle so that the passenger can easily adjust the height using the lever as needed.

When adjusting the height, release the force on the foot of the guide rail and pull the height adjustment lever 68 once to raise the inner column one by one.When lowering the height, press the foot to lower the height while lowering the lever, and then release the lever. It is a height adjuster that is fixed in position.

In addition, since the impact is transmitted downward because the weight is continuously stepped on from the foot, it is preferable to install the shock absorbing member 73 on the top of the inner pillar of the height adjusting device supporting the guide rail, and the height adjusting device is made of a straight line. And the lower part is fixed so that when the height is adjusted, the point of contact with the lower side of the guide rail changes. Therefore, the upper part of the height adjustment device should not be fixed.

The following describes other embodiments that can achieve the above object.

Fig. 9 shows a cylindrical gear 55 vertically provided at the bottom of the guide rail, that is, just below the bottom dead center of the scaffold and between the left and right rack gears without connecting wires in the reciprocating device of the roller gear roller scaffold, and the left and right rack gears. Gears 56 are formed on the inner side thereof so as to be engaged with the intermediate gear 55, so that the rack gears connected to the left and right scaffolds move in opposite directions.

Figure 7 shows that the guide rail and the rack gear portion is made of a straight line, but Figure 8 shows that the curved surface is made of a constant surface like an arc that is part of a large circle. There will be advantages and disadvantages for straight lines and curved surfaces, but this can be used selectively during implementation.

13 and 14 are a front view and a right side view of another embodiment of a power transmission device using a wire and a coil spring.

The power transmission device using the roller gear roller scaffold and a series of gears described above had a bad appearance because the rack gear portion protrudes backward when the roller scaffold descends, but this is to compensate for such disadvantages.

The wire 83 is fixedly coupled to the lower plate of the roller scaffold, and a few turns are wound around the drum 80 provided on the rear wheel shaft with the groove 85 provided at the top of the guide rail and the next guide rail through the roller 84. After the end is fixed. The length of the wire is wound around the drum about 7 to 8 turns when the roller foot is at the top dead center so that some of the wire is wound around the drum without lowering even when the roller foot is lowered.

 The drum provided on the wheel axle is rotated clockwise as the roller foot is lowered and the wire is pulled while the wire is wound on the drum. At the same time, the rotating force is transmitted to the shaft. It will be a one-way clutch to be automatically wound when the step is raised is made by the coil spring (81).

In general, coil springs are used to rewind electric wires in home appliances and are used in clockwork. In this case, the wire is wound around the outer peripheral surface of the one-way clutch, and at the same time, the roller scaffold of the bottom dead center is pulled up to the top dead center.

As described above, the inner end of the coil spring is fixed to one side of the wire drum and the other end of the coil spring is fixed to one part of the vehicle body, and according to the present invention, it is fixed to the rear lower end 82 of the guide rail. In other words, the outer end of the coil spring is fixed to the vehicle body, and the inner end is fixed to the clutch drum. Therefore, when the drum rotates under external force, the spring is forcibly wound or released and the drum is reacted when the external force is released. Rotate in the opposite direction to rewind the wire to lift the footrest.

In this case, even if the left and right footboards are not connected by a single wire, when the user steps on the foot, the wire wound by the weight is released and the rotation force is transmitted to the shaft through the clutch.When the foot is released, the coil spring automatically winds the wire and the footrest is turned to top dead center. Put up and down in the end will be working separately.

The power transmission device configured as described above is capable of transmitting power by rotating the wheel shaft by pulling the wire wound on the drum by the force of the roller scaffold descending by the weight, and being able to move forward by the repetitive action of rewinding the wire. .

FIG. 15 is a perspective view of a wire connected to a lower portion of a guide rail as an example of another power transmission method, as viewed from below. FIG.

Two chain gears (91a, 91b) on the rear wheel shaft is provided with a one-way clutch that transmits power to the shaft and idle in the opposite direction when rotated clockwise spaced apart by the distance of the foot plate.

Referring to the drawings, the one-way clutch 91a, 91b will be described how relative movement is possible in accordance with the up and down reciprocating motion of the roller scaffold.

According to the present invention, since the first step is exerted when the roller scaffold is lowered, one roller scaffold should be rotated to rotate one clutch in the forward rotation direction and the other scaffold rises to reversely rotate the other clutch.

First, one string 92a, 92b, which is connected in series in the order of wire-chain-wire-chain-wire, is provided, the wire is for the roller portion, and the chain is reciprocated only in the chain gear portion. As a line)

One end of the wire connected in series as described above is fixedly coupled to the roller scaffold A and the other end passes through the wire entrance 95a to the top of the chain gear 91a and passes through the rollers 93a and 93b to the bottom of the chain gear 91b to the top of the wire entrance 95b. Once inside, it is fixed to foot B. At this time, the footholds A and B should be positioned at the top dead center and the bottom dead center, respectively, to fix the wire. In addition, it is most important that the two chain parts 92b in the middle do not leave the chain gear while the left and right roller scaffolds are reciprocated between the top dead center and the bottom dead center during operation after being combined and the present invention connected in the above manner. The power transmission device of the roller is to rotate the chain gear of the near side when the roller step is lowered, the other chain gear is rotated reversely, and the other side is raised.

The most important point in this embodiment is that the clutches 91a and 91b rotate in opposite directions when either wire is pulled. If the order of wire and chain connection is not the same as above and the wrong one is in any part, the two chain gears will always rotate in the same direction, and then only one foot should be used and the other foot will be There is a problem that is not balanced because it does not cost. If it is a normal moving mechanism, it is natural to balance the left and right.

As described above, the pair of left and right roller scaffolding is connected to one row, and the object of the present invention is achieved by alternately rotating the two chain gears forward and backward.

In addition, the chain and the wires alternately connected in order to be able to change direction and operate smoothly only if the wire through the roller to be flexible and bendable. Of course, the chain is not only flexible, but also bends only in one direction, and thus, a wire is used at the portion passing through the roller in this embodiment, which is a feature.

In addition, the chain around the chain gear should be prevented from being separated well, but in the present state, the left and right roller scaffolds are not always held tight. If one roller scaffold is always at the top dead center and the other is at the bottom dead center, the tension of the chain and wires 92a and 92b is maintained, but when the user lifts the scaffold at the bottom dead center, the above line is loosened and the chain is peeled off. It can be lost.

Therefore, the wire holding rollers 96a and 96b are further provided as part of maintaining the tension of the chain and the wire around the chain gear at all times. In other words, the wires coming out of the roller scaffold through the wire entrances 95a and 95b are sandwiched between two rollers which are engaged with each other by a suitable force by a spring (not shown), so that the rollers are held by the rollers. The tension of the chain and wire around the chain gear will remain the same.

As described above, in the present invention, the roller scaffold that can be rolled well on the inclined surface by using the inclined surface and the weight transfers power to the rear wheel by the method of various embodiments to move forward by the weight of the new embodiment, which enables the forward movement. It is a form of transportation.

As shown in Figures 1 and 2, the moving means of the present invention is a three-wheeled vehicle having an A-shaped frame (11, 12) structure and the front wheel and the steering wheel has a steering function.

In the present invention, since the power transmission device is finally transmitted to the rear wheel shaft, the wheel must be fixed to the shaft in order to rotate the wheel, and the rear wheel shaft rotates, so that the shaft can be rotated at the connection with the frame. It is to be provided that the combined shaft rotation 22.

In addition, the braking device for the safety of the vehicle is mounted on the rear wheels, and the brakes 17 provided on the two rear wheels are connected by one wire 19 to operate the lever 18 of the handle so that the left and right brakes are the same at the same time. It was to be braked by the force of strength.

The mobile means of the present invention made as described above is stable and can be easily worn by anyone, men and women, and can be used regardless of the outfit because it is standing, and because the weight is transmitted to the wheel as it is, it can make a great effort to climb uphill without difficulty. Not only that, but also can be easily used to carry the load.

Therefore, by properly modifying the shape of the three-wheeled scooter of the present invention can be used for more various applications. In other words, the front of the guide rail to load the luggage compartment 20 to create a space that can be used for carrying luggage and to place a stroller chair for carrying a child will be combined with a stroller. In addition, it is possible to stop and stand. When the reciprocating motion on the footrest is installed so that the rear wheel floats in the air, the wheels are idle and become a non-powered treadmill.

As such, the present invention provides a revolutionary upright walking-type three-wheeled scooter with various useful applications.

Although it is described in detail above, even if it is not described, it is to be considered that the present invention can be applied by common sense within the scope of the present invention within the claims of the present invention.

The walkable three-wheeled scooter of the present invention made as described above has various advantages in that it can stand and ride.

It is a perfect exercise effect because it is standing or walking or running, and it is not harmful to any part of the body even after a long ride.

In addition, it is a useful invention that has the advantage over the bicycle when carrying a load or going uphill because it is able to carry weight in a standing posture can be a great force without too much effort.

In addition, because it is three-wheel stability, you do not need to learn how to ride separately to balance, and anyone who can walk can ride it.

As such, the present invention provides a simple structure by using an inclined surface and a weight, and also provides a walking-type three-wheeled scooter that anyone can use casually due to the low manufacturing cost.
