Description

Production and use of a type of roller and walking wheel

Technical field to which the present invention pertains

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a type of roller and a walker wheel having a transmission structure, and more particularly to the manufacture of a roller which can be driven on a walking or running manner by means of a pair of legs. This type of roller is mounted behind a vertical swing frame or a parallelogram swing frame. The method of making and using a walking wheel that is driven by a walking or running style with a vertical frame.

Prior art prior to the present invention

In order to achieve the purpose of speeding up the walking speed, the force of the user's leg to be depressed after lifting the leg during walking or running is converted into the forward driving force of the roller, and the existing various types of feet with the transmission mechanism There are many different designs in the tactile roller product. However, from the perspective of the final use effect, these known structures have problems in almost two degrees. First, the complexity of the transmission structure is not only high in cost, but also has certain reliability and durability. For example, under the impact of leg running, the transmission rack gear may be damaged. Second, the diameter of the roller is small. When most of the structure is in use, the height of the user's sole from the ground is greater than the diameter of the roller. This brings a dilemma. In order to improve the roller passing ability, it is desirable that the diameter of the roller is larger. However, in order to lower the standing height of the user, it is desirable that the diameter of the roller is smaller.

In various wheeled vehicles driven in a standing manner, the current mainstream mode is also frame type, that is, the wheels are mounted on the frame, and the user's hand grasps the balance of the vehicle and balances the direction of the vehicle during operation. The user drives the roller on the frame with walking or running on the legs. This type of device runs smoothly, but its basic force-bearing structure is actually a reduced-type bicycle or scooter. It also requires a solid frame to support the user's weight, thus reducing the size and weight. The effect is not satisfactory. In order to avoid these deficiencies, there are some typical structures of different parallel two-wheeled standing wheels, such as The "XEGLET" car that won the gold medal at the 2003 International Bicycle Design Awards in Taiwan, China, is the typical "SEGWAY" electric scooter produced by SEGWAY in the United States in recent years. From the perspective of the use effect, there are still major limitations. For example, the former wheel is only a pulley without a transmission structure, and the wheel diameter is also small, and the walking speed is too slow. The latter is a simple electric drive, and the structure is complicated and expensive, which is not conducive to popularization.

Purpose of the invention

The invention has the following two purposes:

A. In terms of the structure of the roller, it is to avoid the disadvantages such as the complicated driving mechanism, the vulnerability of the transmission mechanism, the small diameter of the wheel, and the like, and the provision of a simple, reliable, durable and durable structure. The relatively large wheel diameter and the method of making and using the pedal-driven roller that fully conforms to the walking or running motion of the human leg and foot.

B. The structure of the walking wheel is to avoid the shortcomings of the existing standing wheel vehicles in the driving mode, and the disadvantages of large volume, heavy weight and high cost in different degrees, and provide a class of the invention. The roller is combined with a vertical swinging frame or a parallel quadrilateral swing frame to make and use a walking wheel, which is small in size, light in weight, simple to use, convenient to drive, and versatile. All types of people can use the transport or both.

Technical solution adopted by the invention

In order to achieve the above two objectives, the present invention is implemented using the following technical solutions.

In terms of the manufacture and use of the roller structure, a set of roller system has two rollers arranged in parallel or in-line, with a crank between the two rollers, the crank can rotate around the axis of the two rollers, and the pedal shaft has a pedal shaft at the top. The pedal is mounted on the pedal shaft, and a strap is provided at a suitable place on the pedal for fixing the user's foot. One of the rollers is driven by the overrunning clutch and the crank, when the foot of the person's leg is stepped on the pedal and tied After the belt is fixed, when the legs swing and walk or run, the foot can swing forward when it is swung backwards at the lowest point of the crank, or when the foot is lifted to turn the crank to the highest point and then step down. Rolling, the trajectory of the foot is basically the same as the sinusoid of the roller driven by the pedal pedal.

From the point of view of the use effect, the roller structure of the present invention has greater advantages and obvious beneficial effects in the following two aspects in comparison with the existing various types of structures in terms of production and use methods:

1. When the user walks or runs, especially when jumping a lot, the impact force on the foot is very large. These impact forces have certain mechanical damage to the rollers driven by the gears such as the rack gear. At the same time, this type of transmission does not have any cushioning protection for the joints such as the human leg. The roller structure of the present invention can better avoid these defects, because the user's foot stepped on the pedal and the roller is rotated by the crankshaft through the overrunning clutch, and there is no damage problem of the rack and pinion, and the most important is that the crankshaft is The circular motion around the axis of the roller has a certain buffering protection for the joints such as the human leg, and the rotational inertia of the crank and the wheel can be well utilized in rapid motion.

2. There are various types of rollers equipped with transmission structure. In order to balance the stroke requirements of the transmission mechanism and ensure a certain height of the center of gravity, the diameter of the roller can only be reduced, resulting in a decrease in the ability to pass the road. The roller structure is a two-wheel type, and the two basic structures can be arranged in parallel or in a straight line, and the crank rotates around the axis of the two rollers between the two rollers, and is mounted on one of the roller shafts. Overrunning clutch with crank drive. The height at which the user stands at the center of gravity of the roller in this configuration does not depend on the diameter of the roller, but on the length of the crank. Therefore, the roller structure can also obtain a lower standing center of gravity while using a larger diameter roller.

The above describes the two kinds of pedal driving rollers that can be worn on the feet. When using, the feet can be directly used on the pedals of the roller, and the horizontal thrust of the legs can be grounded due to the large diameter of the wheel. And the vertical pressure can be converted into the driving force of the roller, which can achieve faster taxiing speed and strong road pass. Ability.

On the other hand, like all kinds of wheel shoes, roller skates, and inline roller shoes that need to be worn on the feet, these rollers require some skill in use, but for many people, because they can't keep their body during exercise. Balance can't make it widely used like a bicycle.

In order to solve the above problems, the method for manufacturing and using the walking wheel of the present invention can mount the roller on a frame of different structure on the basis of completely retaining the roller and the transmission structure, and driving the legs to swing or run. By simultaneously controlling the wheel and the vehicle by the user's hands and feet, the roller can be combined with the vertical swinging frame or the parallelogram swinging frame to become a popular wheeled and freight car.

In terms of the production and use of the walking wheel, the basic arrangement of two different walking wheels composed of a vertical swinging frame or a parallelogram swinging frame can be added to the different arrangement of the rollers of the present invention.

1. The walking wheel consists of two sets of side-by-side rollers or in-line rollers plus a vertical swinging frame. The frame consists of two vertical bars and a cross bar that can swing about the axis of both ends of the crossbar. One end of the two vertical rods is mounted on the rotating shaft of the two sets of parallel rollers by bearings, or on the rotating shafts of the front wheels of the two sets of in-line rollers, and the other end can be used by the user's hands to control the balance of the body.

2. The pedestrian wheel consists of two sets of in-line rollers plus a parallelogram swing frame. The frame consists of two sets of two parallel bars and a parallel bar and a crossbar. The two sets of parallelogram side frames can swing parallel around the axis of the two ends of the crossbar. The lower ends of the two sets of parallelogram side frames are mounted on the rotating shafts of the two sets of in-line rollers by bearings, and the two front vertical bars at the upper end are longer, so that the user's hands can hold the balance of the control body.

When in use, the user's feet stand on the pedals of the two sides of the roller, and the two hands hold the two vertical bars respectively. The top handle of the frame, and the brakes are added to the corresponding parts. While walking, the hands and feet on the same side swing in opposite directions. When the two legs swing and walk or run, the trajectory of the foot is basically the same as the sinusoid of the roller driven by the pedal pedal, and the driving roller rotates forward. At the same time, the two hands hold the two vertical frame to control the balance of the body. Through the brake control of the side rollers during cornering, the purpose of smooth and safe operation is achieved. When towing, the wheeler can be a hand-drawn trolley without any modification.

In view of the use effect, the pedestrian wheel vehicle of the present invention has the following advantages and obvious beneficial effects in comparison with the existing similar standing wheel vehicles.

First of all, the weight of the user of the wheeler is basically carried by the pedal, the pedal shaft, the crank and the roller, and the frame is basically unstressed. It can greatly reduce the weight ratio and volume ratio of the frame in the whole vehicle.

Secondly, compared with the XICLET car with the closest structure, the frame structure of the wheeler has a crossbar, so that the two vertical bars swing around the axis of the two ends of the crossbar at a certain distance. When used, it is more in line with the physiological movement structure of ergonomics. It is also more convenient to maintain body balance while running. More importantly, the roller has a crank transmission structure that passes the overrunning clutch. When the user swings the legs and walks or runs, the leg swings backwards at the lowest point of the crank, or the foot lifts up to turn the crank. When the highest point is pressed down, it can drive the wheel car to move forward. Its running speed can be close to the running speed of ordinary bicycles.

Third, compared with the US "SEGWAY" electric scooter, because it does not require a complicated balance system, the wheel is much superior in terms of structure, weight, cost, etc., and can also be mounted on the vertical frame. The motorized drive mechanism becomes a motorized scooter.

The two-sided symmetrical crank 4 is mounted on the pedal shaft 5 at the outer end of the crank, the bearing seat of the pedal 6 is sleeved on the pedal shaft 5, and the foot strap 7 is provided at a suitable place on the pedal 6.

When in use, the user's one foot is stepped on the pedal 6 and fixed with the strap 7, when the foot is depressed to make the crank After going to the bottom dead center, the foot starts to lift upwards while dragging the entire roller group to slide forward. When the foot is lifted to the top dead center of the crank 4, the pedal 6 is pushed down, and the crank 4 is driven by the overrunning clutch 2. The roller 1 is rotated forward until the crank 4 is turned back to the bottom dead center, and the roller 8 is always in a freely rotating state.

In Fig. 2, the front roller 9 and the rear roller 19 of the in-line roller have the same diameter, the crank 12 and the crank 21 have the same size, the front roller 9 is provided with an overrunning clutch 13, and the axle 14 is equipped with a frame 15 to connect the front and rear wheels. At the outer ends of the crank 12 and the crank 21, the pedal shafts 10 and 20 are coupled with the swinging rod 11, and the pedal 16 is fixed at a suitable place of the swinging rod 11. The pedal 16 is provided with a foot strap 17 on the upper side of the pedal 16 for the user's foot 18 is fixed on it.

When the pedal of the foot drives the cranks 12 and 21 to the bottom dead center, the foot 18 starts to lift upwards while dragging the entire roller set. Slide forward, when the foot is raised to the top dead center of the cranks 12 and 21, the pedal 16 is depressed downward, and the roller 9 is driven forward by the crank 12 via the overrunning clutch 13 until the cranks 12 and 21 are turned back to the lower end. Point, while the roller 19 is always in a freely rotating state.

In Fig. 3, the basic structural schematic diagram of the walking wheel after the vertical roller is mounted on the vertical swinging frame. In the vehicle structure, there are two sets of mirror-symmetrical roller systems. One of the trains has left and right rollers 22 and 29, an axle 23, a connecting frame 24 of the roller 22 and the roller 29, a crank 27 between the two wheels, a pedal 25, a strap 26 on the pedal 25, and a crank 27 passing through The overrunning clutch 28 and the roller 29 are driven, and the two sets of wheels have vertical frame 30 and 38. The appropriate part of the frame 30 has a rotating shaft seat 32, and a U-shaped cross frame 36 is fixed on the vertical frame 38. At one end of the frame 36, there is a rotating shaft seat 34. The rotating shaft 35 passes through the bearing housing 34 and the bearing housing 32, and is coupled by a nut 31. The two side frames can swing around the shaft 35, and are respectively mounted on the top of the frame 30 and the frame 38. There are brake devices 31 and 37 for braking the outer rollers of the two sets of trains, respectively. When in use, the user's left and right feet are respectively stepped on the pedals of the two sets of roller cars, and tied with straps, and the two hands grasp the handles of the frame of the two vertical bars, and can walk normally. For example, when the left leg is taken forward, the frame 30 and the frame 38 are swung around the shaft 35, and the left foot is raised until the crank 27 is turned to the top dead center, the pedal 26 is depressed downward, and the crank 27 is passed through the overrunning clutch. 28 drive roller 29 rolls forward until the crank 27 turns to the bottom dead center. At this time, the right foot starts the same process, and the two legs alternately swing and lift up like a road, because one of the rollers on both sides is equipped with a roller. Clutch, this roller can't be reversed when rolling. At this time, whether the two feet are swinging or stepping on the pedal, it can push the forward sliding of the walking wheel. When it is necessary to turn, the brake device 33 or 37 which needs the turning direction can be grasped by both sides, and the wheeled vehicle can be turned, and the brake devices 33 and 37 can be grasped on both sides to stop the vehicle.
