Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for effectively converting human power into rotational motion.

Conventionally, as a mechanism for converting human power into rotational motion, there is a lever mechanism used for a roller through the crank mechanism of a bicycle or the like.

Most bicycles have a crank mechanism, but since the crank requires rotational movement of the legs, in the case of a seated rower, pedal effort is wasted at the dead center, and if you stand up, the motion becomes unnatural and difficult to row. There are drawbacks such as.

To raise the pedal from the lower end to the upper end, a crank uses part of the pedal force from the opposite foot to convert it into rotational motion, and a roller through uses spring force, so part of the pedal force is used to turn the pedal into rotational motion. I use it to effectively rotate the pedal force.
I haven't changed it into a movement.

Also, there are bicycles that have toe clips attached to the pedals, but since the left and right pedals are linked in the crank mechanism, the pedal cannot be pulled up unless the foot that is pulling it up is fast enough, even if the speed of the opposite foot is not as fast. I can't. Therefore, as the name suggests, toe clips are thought to be attached to prevent your feet from slipping off the pedals when you pedal fast, such as in a bicycle race, when the speed at which you pull up becomes too fast. That is, in the case of a crank-type bicycle, there are drawbacks such as the fact that at normal pedaling speeds, the speed at which the bicycle is pulled up is slow and the pedals must be pressed down a little, and even if a toe clip is attached, it does not have the effect of pulling up the pedals.

The purpose of this invention is to provide a mechanism that makes it easy to row by foot and allows for quick rotational movement.The outline of the invention is as follows.

First, the natural movement pattern of the foot is reciprocating motion.

Therefore, in place of the crank, we used a lever mechanism that swings left and right independently to make it easier to row by foot.

Since only one foot makes a reciprocating motion, use this to attach a return buckle to the pedal to make the lever swing. The left and right levers are not interlocked and move independently, so even if you row at normal speed, you can swing the levers with just the power of one foot. The oscillating motion of a set of levers matches the natural reciprocating motion of the foot and effectively generates rotational force, and if the pedals are fitted with return hooks and swing back and forth, rotational motion can be obtained efficiently.

An example of applying the present invention to a bicycle will be described with reference to the drawings.

A return buckle is a device that is attached to the pedal in order to return the pedal to its original position by using only one foot to return to its original position after pedaling. The material of the return metal must be hard so that the foot does not come off the pedal when the pedal is lifted, but it must be made of a soft leaf spring-like material so that there is no play between the foot and the foot even if the feet are different sizes due to footwear etc. Made of elastic material. In order to make it easier to put your foot inside the return metal, a conductor 5 is attached with a diagonally spread out opening, but there is also a conductor edge 10 with a large green area so that it can be easily separated.

There are two types: horizontal type 3, which is attached to the side of the pedal, and front type M9, which is attached to the front. The return buck shown in Figures 5 and 6 is a slippery type 14, which can be used when swinging the lever at an angle close to the vertical direction as shown in Figure 6. If the pedal stopper 16 is attached, the pedal can be returned to its original position even if the foot leaves the pedal, making it suitable for a treadle type bicycle. Also, make the hook-type return metal 14 square! 7. If the tube 15 is made circular, it will be a line contact, so it won't be easy on the bell and it won't damage your footwear.

When you put a return metal on the pedal, the front becomes heavier and the rotation becomes vertical. This makes it difficult to ride the bike, so adding a pedal stopper 4.24 will make it easier to ride the bike while it is slightly tilted. However, if your bicycle falls over, you may get injured if your feet do not come off the pedals easily, so it is better to allow the pedals to rotate as freely as possible without having a stopper. Therefore, the fourth step is to make sure that the pedals are not vertical and can rotate so that they are easy to ride on the bicycle.
As with the pedals shown in Figures and Figure 12, the rear can be made a little longer to accommodate the weight of the return metal for better balance. There are two types: horizontal type 8, which is attached to the side of the lever, and front type 21, which is attached to the front. Since lever #'i only swings, depending on the arrangement of the mechanism, the tip of the lever may be slightly bent inward, and the width of the left and right pedals may be narrowed so that the foot does not become crooked.

The different types of return buckles and pedals can be combined appropriately and attached to each lever.

The levers are divided into two types: a foot-operated lever as shown in FIGS. 1 to 4, and a step-operated lever as shown in FIGS. 5 to 10.

For foot pedals, use the pedal so that the pedal force or kick force acts on the lever at a right angle as much as possible. For the stepping type, use the lever so that the resultant force of the stepping force and walking force acts at right angles to the lever. Walking power is the force you get when walking on a flat road, and because it is the frictional force with the ground, you stand and pedal so that your weight is on the pedals.

The treading type is the resultant force of treading force and walking force, which is similar to the force when climbing a slope. When walking, it is natural to lift the legs instead of leaning on them, so we designed the hook-type return hook 14 and the telescoping lever 18 so that the legs can be moved in a natural shape. As shown in FIG. 9, the fixed side 18 of the telescoping lever has a rectangular (polygonal) cross section, and the telescoping side 19 has a circular cross section to form a line contact, making it easy to expand and contract with less friction. The longer the sliding portion is, the easier it will be to slide even if a force other than the expansion/contraction direction is applied.

Next is the speed increasing mechanism, but since this lever can use leg force more effectively than a crank, it has a greater rotational force. However, the swinging motion of the lever is less than half the rotation of a single saw. Therefore, if you pedal the same way, your speed will be slower than a conventional bicycle unless you increase your speed by at least twice as much.

An easy way to do this is to increase the magnification of a conventional chain gear, but to increase speed, an internal gear is used.

Using an internal gear (as opposed to using an external gear) requires one less gear and simplifies the speed increasing mechanism. Internal gears are either attached to a lever and rotated, or attached to a freewheel shaft and rotated. When attached to a lever, it is joined by welding or the like, but if it is necessary to increase the strength by narrowing the distance between the arms at both ends, the arms 26 are made outside the plane of the tooth row. The internal gear 25 is then welded or riveted to the arm plate.

By attaching the freewheel 11 directly to the lever and attaching a chain gear or internal gear to the shaft to increase speed, the swing inertia can be reduced.

Figures 11 and 12 show a foot-pedal bicycle, which converts pedal effort into rotational force. It burns as naturally as possible with foot movements and effectively converts it into rotational force. Unlike a crank, the left and right pedals do not work together, so you can burn without shaking your body even if you stand up. In the mechanism, the lever 31 is swung between the upper end B and the lower end A around the swing shaft 3 (F) by stepping on the pedal 32 with the return metal 33 attached. An internal gear 34 attached to the lever meshes with a gear 37 with a freewheel 38 to increase speed. The internal gears attached to the freewheel shaft 36 #i and the left and right levers act in this manner to rotate. Therefore, rotational motion can be transmitted from the chain gear 39 attached to the freewheel shaft to the chain gear 40 and chain 41. of the rear wheel.

There is a stopper so that the lower end A is the lower limit for the standing K, but the end of the lever should come into contact with the diagonal pipe 28 of the frame and stop. If there is a sound, the sound can be reduced by pasting hard rubber or the like on the affected part or by creating a stopper near the swing shaft 30. If you are rowing seated,
It will stop when it hits the stopper, but if you stop without hitting the stopper, you can use the pedal force effectively to the end. Therefore, the height of the stool should be adjustable, rather than letting it burn just above the lower limit.
Adjust the height to suit your leg length.

Figures 13 and 14 are treadle type bicycles, which generate rotational force from the resultant force of pedal force and walking force. The treadle-type rower has a motion similar to climbing stairs, but the treadle-type rower has a gentler incline and rows like climbing a hill, so you won't get tired even if you stand and row for a long time.

The mechanism uses a telescoping lever 47 to swing a pedal 48 with a return metal 49 in a walking motion from the front end to the rear end C around a lever swing shaft 46. The internal gear 53 attached to the collar 1 is the gear 5 attached to the freewheel 560.
5 and increases speed.

The freewheel shaft 54 rotates as the internal gears attached to the left and right levers act as freewheels, respectively. Therefore, rotational motion can be transmitted from the chain gear 57 attached to the freewheel shaft to the chain gear 58 of the rear wheel by the chain 591. The lever stopper is located at the bent part 51 of the diagonal pipe 42 of the frame or at the joint between the vertical pipe 43 and the arcuate pipe 44, but K, which reduces the hit one sound, should be placed as close to the swing axis 46 as possible. You can attach hard rubber, etc.

Since this mechanism uses a forward-extending pedal 48, the width of the left and right pedals is narrow and does not overlap. The longer the length of the lever, the closer the pedal travel will be to a straight line instead of an arc, and it will burn with a more natural movement shape, but there is a limit because it has to be a small si#, which can be used manually.

Although the above description has been made using a bicycle as an example, this mechanism can be used in a boat or other applications in which rotational motion is obtained by human power.

As explained above, this invention is a mechanism that obtains rotational motion by human power, and if the crank is replaced by a lever that swings independently, a return metal is attached to the pedal, and an internal gear is used to increase the speed, Human power can be used more effectively and turned into rotational force. This makes it easier for people to burn because they only have to make back-and-forth movements, and even if they stand, they can burn using natural movement. Also, since the rotational force increases, the rotation speed becomes faster, and it becomes easier to climb up a slope.

(Continued to line 18) 14 from the top of page 8 . Add line 15 to the next sentence and correct it. Therefore, the front type return metal 9 can improve the spring strength, but since the front of the pedal is not heavy, it needs to be balanced at the back.Horizontal type return metal 3 Is it desirable to have the pedal tilt too vertically even if the balance is not set at the rear, or do you need to devise a way to control the spring?The diagonal return bracket 63 is in the middle. 8 and the front-loading type 21. Then, it continues to the 16th line, ri) Correct the lines 1 to 5 from the top of page 10 to the following sentence. Sorry. However, the lever (,1' swings) In this case, the speed will not be faster than the conventional rotation! 11" unless it speeds up several times. (Line break continued from line 6) 10 from the top of page 10 The 14th line has been corrected to the following sentence.The internal gears have two different types: δ when they oscillate on the lever, when they rotate separately on the lever shaft. When attaching an internal gear, place the arms on both ends of the tooth row in the same plane (j, as shown in Figure 1.2, move the lever %, Ii
Something to do is coming. If you want to improve the spacing between the arms (1'l'11), place the arm 26 outside the plane of the tooth row (continued to line 15) Next to line 19 from J- on page 10. Add a new line and add the next sentence. Next, as accessory parts, I added the bicycle 1□2 shown in Figures 15 to 20 to include a riding wheel and a stand so that when you are riding a bicycle and want to stop, you can do so by bending your toes. With conventional crank-type bicycles, you only need to lower your legs when you stop and move, but this lever-equipped bicycle has full return levers, so it is a little difficult to lower your legs. Heavy wheel stand 73.93 , 112 is activated by pressing the pedal 1.
4 Near stopping points F, H, A, turn the tip of your foot to the pedal (Pedal claw for bicycle stand 80.9'8,1
17. This acts on the heavy wheel stand to ground it, allowing you to stop while riding the bicycle. There are weight type and spring type to keep the riding stand from touching the ground when not in operation.
．． Figure 18, Figure 1-J, Figure 19.20 is an example of the latter. The weight type requires a weight of 76.95 mm, but if you make it so that it roughly balances the weight of the bicycle stand, you can ground the heavy bicycle stand with just a light turn of the pedal. Also, the point where you turn the pedal when sitting is a little above the lower stop points F, H, and Δ, which requires some ingenuity, so you have to turn the pedal near that point so that the heavy wheel stand (B) will touch the ground. Here, the part where the pedal pawl acts is made into a cam curve. In the case of Figures 17 and 18 and Figures 19 and 20 (j
2.The position where you sit down and turn the pedal to activate it is close to the bottom end point, so I shifted the shape of the heavy wheel stand at the pedal claw or the action part to the cam curve (where to turn the pedal near the bottom end point? However, in the case of Figures 15 and 16, it is activated when the pedal is seated, and it is activated at position 1 or I2' when the pedal is seated. Then, as shown in the figure, a cam 75 for the raiwa stand is made separately using a heavy wheel stand Wli aid that uses a link mechanism, and the pedal claw 8 (F) is applied to it. When the pedal pawl acts on the cam 75, the link mechanism integrated with the cam 75 operates, and the pin touches the heavy wheel stand to the ground.
It is meant to work like that. As a result, the swinging range E is not extended near the upper end of the pedal.
, F can be operated by turning the pedals at the lower part between them. Also, if you have to bend your toes while stopping, or if you make the operating angle of the pedal pawl and cam curve at right angles, you can maintain the heavy-wheel stand for a little while and stop easily. I feel sluggish. 3-3 was mostly made like that, but 19th.
The spring type shown in Figure 20 requires a little maintenance force because the spring counter-cam is applied. The heavy wheel stand can be used by making a ground contact part diagonal to the direction of travel and using it as a light auxiliary brake gear 8, or by attaching a small wheel to the ground with one foot and pushing with one foot to make it easier to advance gradually. The thing to be careful about is to make sure that the pedal claws are as far inward as possible so that they don't get in the way (k), and the width of the heavy-wheel stand should be narrow, or it should be wide enough so that it won't fall over when it gets a little bit of crosswind while it's stopped. , conventional saddles are hard and uncomfortable to sit on, t7)
Te, is it the waist of the net like each figure of 15.19.21 (
[J] [J] This has a vibration-proofing effect and is good for riding, and if you leave your bicycle outside on Mt. 11, you can use the internet. You can get on the bus right away. However, due to the way the chair is pedaled, the rear kick type bicycle chair shown in Figures 17 and 18 has been made narrower than the conventional zatle, so that people can sit astride it.However, the core frame is wrapped with a soft elastic layer. , Cover it tightly with plastic to prevent it from becoming uncomfortable. (Page 10) Continued from line break ivy line 20) On page 13, add a line break and add the legal text after lines 2 to 9. Figures 15 and 16 show a front-kick type rocking internal gear bicycle, which converts the forward kicking force into rotational force. This bicycle has a pedal swing range between E' and I"' that corresponds to sitting pedaling.
When rowing while standing, it is difficult to row because the pedal swing range is backwards diagonally. Then, if you take a sufficient length downward from F' and set it at the bottom end point F, when rowing while standing, the part of the pedal swing range E and F that is perpendicular to the bicycle's direction of travel will be the part of the pedal that is perpendicular to the direction of bicycle travel. To make this possible, the lever's swing axis was positioned at the rear wheel axis, and the length of the lever was made longer. However, since the rear wheel rotates at increased speed, install a lever on the rear wheel shaft (instead of a lever, attach the lever to the core frame or support rod of the rear wheel. Also, install a long lever with a swinging internal gear. Since the oscillating inertia becomes large and difficult to row, make it as light as possible with 4-rows and a light feed material such as aluminum alloy or fiber-containing synthetic resin. Is a stopper necessary so that the lever can oscillate within the oscillating ranges E and F? As with other types of bicycles, the explanation of the lever stopper will be omitted below.In order to make stable rocking movement of the swinging internal gear 64 of the lever, it is necessary to install it on the side of the main frame. A line contact guide is attached (just pull the pedal).The method of pedaling differs for each model, but in the case of the oscillating internal gear type,
The mechanism for rotating the rear wheel using the chain by rotating the lever by an oscillating motion is basically the same as that explained in FIGS. 1112 and 13.14, so the explanation will be omitted. Figures 17 and 18 show a rear-kick type rocking internal gear bicycle, which leans slightly forward and uses rotational force to kick backwards. In order to make it easier to push with the force of kicking backwards, the length of the lever was increased by changing the position of the swing axis 8I of the lever to the position below the rear wheel. Since it is a long lever with a swinging internal gear, it has a streamlined shape and is lightweight, just like the front kick type swinging internal gear type.
4 to reduce the swinging inertia force. In this figure, the basic mechanism is the 1st +
, 12, 13. Since this is the same as in Figure 1/1 and Figures 15 and 16, the explanation of the mechanism will be omitted. Tilt the zattle slightly forward (the reason for this is because it is easier to row with a backward kick in a forward leaning position. In a forward leaning position, air resistance is reduced by 6). Figure 19.20 ( '' A foot-type rotary internal gear-type bicycle turret converts the force of the foot into rotational force. To achieve natural foot movement, lengthen the lever and connect the upper end B and the lower end A. It is better to make the tilt angle a little smaller.However, as the swing angle of the balance and the saw becomes smaller, the speed must be increased (the No. 1 rate must be made thicker.The mechanism of the iron must be made smaller. Therefore, the speed increase magnification cannot be set very carefully.Then, in order to reduce the swinging inertia of the lever, the swinging internal gears were added (instead of the lever shaft, the internal gears rotating in the second direction were turned one by one). The mechanism has a freewheel 103 on each lever (when the lever swings), an internal gear 104 on the lever shaft rotates in a fixed direction.
The speed is increased by meshing with the 4-wheel vehicle 105. Chain 10 from chain gear +07 on the same axis as small gear 105
8 transmits rotational motion to the rear wheels. It is a simple and efficient bicycle with a small oscillating part. A type of bicycle in which the swinging shaft of the lever is placed under the foot of the pedal kick-type bicycle, and the direction of the pedal is fixed in the direction of the swinging radius, so that it does not rotate around the pedal shaft. δ is obtained. Therefore, since this bicycle is pedaled by applying a constant force at right angles to the radial direction of the oscillation, it is possible to efficiently obtain rotational motion, even though the bicycle is first pedaled and then pedaled by the kicking force. However, since the direction of the pedals on this bicycle is fixed, C) it is necessary to use a tricycle to make it easier to get on and off. Also, since the direction of the pedals is fixed, it is difficult to pedal while standing, so Section 1 is omitted. Figure 21.20 shows a simple pedal type bicycle, which is pedaled by rotating the pedals half a turn to convert the pedaling force into rotational force. Instead of a conventional crank, this bicycle uses a lever with a return lever, so the speed increase ratio cannot be increased. Therefore, it is necessary to shorten the lever and widen the swing angle of the row, and the short lever is more like a half-turn row than a foot pedal. Therefore, as for constant force, there is no way to row a conventional crank pedal in a long radius of rotational force other than near the top and bottom dead center where it is efficient to obtain a large rotational force. Adjust the height of the seat so that you can sit down to a point slightly above the bottom end of the pedal.
] can be used effectively until the end. The mechanism is as follows: ``A freewheel 122 is attached to each bar to turn the swinging motion of the lever into a rotational movement in a fixed direction, and a chain ridge 123 attached to the lever shaft is rotated.
This is a simple foot pedal bicycle. Mukobe 2 is a winter type bicycle, and each bicycle has a f.
-The levers, internal gears, pedals, and stand for one-wheel return are not limited to the combinations shown, but other types of parts may be used if appropriate. In addition, since the rotation speed of the lever set with return metal is a little faster than each type, it is better to install the transmission. Although the above description has been made using a bicycle as an example, this mechanism can also be used in other applications such as a boat where rotation is obtained by human power. As explained above, this invention is a mechanism that obtains rotational motion by human power, and instead of a crank, each lever is swung separately, and the lever's pedal has a return metal, and the speed is increased using an internal gear, etc. , 6 manpower! :(-J effect is used to obtain rotational force. 1) It is easy for the rider to row because he only needs to shift the reciprocating movements such as stepping on his feet, and especially when rowing while standing, he can use natural foot movements. It burns.Also, since the pedal spacing can be made a little narrower than on a conventional bicycle, it burns instead of crabbing.Also, since the rotational force is increased compared to a crank type bicycle, the speed increases,
It has the effect of making it easier to climb up a slope by adjusting the b speed. (Detailed description of the invention.

Claims (1)

[Claims] 1. A mechanism in which a lever (31) is caused to swing by a pedal equipped with a return metal (33), and rotational movement is obtained by using a freewheel (38).

Adjust the height of the seat so that you can row a little above that level when rowing seated. Speed increase is performed by a swinging internal gear (34) and a chain gear (39) attached to the lever. 3. ``Pedal type bicycle with rotating internal gear type speed increase device'' points are 2.
It is the same as the foot-operated type described above, but the lever with a freewheel (7) and speed increase are performed by a rotating internal gear and chain gear attached to the freewheel shaft. ○ "Front kick type bicycle" The key points for sitting down are as follows. The angle between the line connecting the base end (E) and the front end (F) of the pedal and the horizontal line is approximately 50°, and the horizontal distance from the base end to the front end is approximately 35 cm. The front end is not the stopping point of the lever's swing, and it still moves forward a little. ○ ``Rear-kick type bicycle'' This bicycle can be used for both sitting and standing riding, and the details are as follows. The angle between the line connecting the base end (G) and the rear end (H) of the pedal and the horizontal line is approximately 30°, and the horizontal distance from the base end to the rear end is approximately 35 cm. Adjust the height of the saddle so that when rowing standing, the rear end becomes the stopping point, and when rowing seated, you can row just a little before that point. ○ ``Pedal type bicycle'' This is a seated type bicycle, and the key points are as follows. Place the pivot shaft of the lever just below the saddle, and make the lever approximately 40cm long. The rear end (J) is not the end point of the lever's swing and is still moved a little further back. 4. ``Tread-pedal bicycle'' The key points for standing bicycle are as follows. The angle between the line connecting the rear end (C) and the front end (D) of the pedal and the horizontal line is approximately 30°, and the horizontal distance from the rear end to the front end is approximately 40 cm. A telescoping lever (18) with an internal gear or a hook-type return metal (14) is used. 5. ``Vertical foot-pedal bicycle'' It can be used for both sitting and standing bicycles, and the details are as follows. The line connecting the bottom end (K) and top end (L) of the pedal is almost vertical, and the height from the bottom end to the top end is approximately 35 cm. Adjust the height of the seat so that when rowing standing, the lower end is the lower limit, and when rowing seated, you can row a little above that limit. It is a simple mechanism consisting of a lever with a freewheel (7) and a chain gear.
