Abstract

A sports equipment being fixed to both feet just like a roller skate and increasing the walking speed by rolling the wheels through walking motion. The sports equipment comprises a drive mechanism functioning to rotate the wheels by the force of a foot and the force of a spring when the ankle is raised, wherein the drive mechanism incorporates, in the middle thereof, at least one unidirectional rotary clutch so that the walking speed can be increased while preventing the kicking foot from flowing rearward by performing the kicking operation simultaneously with the motion for raising the ankle at some specified point. In Fig. 1, the motion for raising the ankle acts as a rotating force onto a sprocket (8a) incorporated in the unidirectional rotary clutch to rotate the wheels (13) unidirectionally. The walking speed can be increased while preventing the kicking foot from flowing rearward by performing the kicking operation simultaneously with the motion for raising the ankle at a specified point where the wheels (13) are accelerated through rotation of the sprocket (8a).

Specification

Sports equipment for assisting walking

Technical field

The present invention relates to a sports equipment that rolls and moves by a wheel, such as a roller skate or an in-line skate, in which a drive mechanism is provided for a sports equipment of a style in which one is mounted on one foot and two are mounted on both feet. The drive mechanism is related to sports equipment that generates driving force by raising or kicking the heel.

Background art

Conventional sports equipment that rolls with wheels, such as roller skates and in-line skates, has two types of sports equipment, one on each leg and two on both legs. No one had a drive mechanism that produced

Also, conventional sports equipment such as roller skates and in-line skates use a ratchet-type anti-reverse wheel, or have a one-way One that incorporates a rotary clutch between the wheel frame and the wheel to prevent the wheel from reversing is known to be easy to kick out when kicking forward. Also have common weaknesses. It is moving forward, while the wheel is rolling, if you kick it with your feet and try to accelerate, the kicking foot will flow backwards, working to counteract the rotation of the wheel, The point is that you can not kick until it stops against the wheel frame. The moment I can kick and accelerate is a wheel frame Both the wheel and the wheel are at rest against the ground. In other words, it is effective for kicking from a stopped position, but is not effective for continuous acceleration during rolling movement. And because the feet flow backward, energy is wasted.

When a similar drive mechanism is used, a skateboard with a one-way rotating clutch incorporated in the middle of the transmission of power as shown in the publication number of Japanese Patent Application Laid-Open No. 8-164234, such as a skateboard or a bicycle, may be used. The technique of incorporating a one-way rotating latch / patch in the middle of transmission is well known. However, all of these methods use the foot to depress the pedal or plate to rotate the wheel, and do not generate driving force by raising the heel or kicking. This method has no example. Nor are they sporting equipment, one on each leg and two on both legs.

In the case of conventional sports equipment that moves with rolling wheels, such as roller skates and inline skates, sports equipment with one on one foot and two on both feet is moving forward, that is, moving with the wheel rolling If you try to accelerate by kicking in a walking motion, the kicking feet will flow backward, and continuous acceleration will not be possible. When kicking and accelerating, there was a problem that the kick foot or the wheel was always stopped with respect to the ground, or the wheel was in a reversed state, resulting in a large energy loss. The present invention has been devised so as to eliminate such a state, minimize energy loss, enable continuous acceleration, and allow the wheel to be rolled and moved lightly.

In addition, when a mechanism that depresses a pedal or a plate to rotate a wheel, as in the prior art, is incorporated into a sporting equipment of the style of the present invention, the foot is stepped forward in a walking-like motion, and the foot is moved from the heel. If you try to lower the heel first, it is too hard to lower your heel. There was a problem that it was not possible to stand, and that when trying to stand still on the spot, trying to lower the heel caused the force to move forward due to the load, making it difficult to stand up. The present invention has been made to solve this problem. DISCLOSURE OF THE INVENTION 'In order to solve the above problems, the present invention incorporates a drive mechanism that acts to accelerate the rolling of the wheel when the heel is raised in a walking motion. When the heel is raised or the foot is kicked, the rolling motion of the wheel keeps moving forward, and the wheel does not reverse. The specific point is defined as the point at which the rotational force generated by the heel-raising or kicking motion is synchronized with the rotation of the wheel.At this specific point, the heel is lifted with a stronger force and kicked, thereby causing the wheel to reverse. You can accelerate the forward movement of the wheel without it. In order to provide this function, the present invention adopts a structure in which one or more unidirectional rotating clutches are incorporated in the middle of the power transmission path from the drive plate that transmits the operation of raising the heel to the rotation of the wheel. It is. As a result, raising the heel not only has the effect of rotating the wheel, but also allows the player to kick at the same time, thus solving the above problem.

In addition, the present invention incorporates a drive mechanism that operates when the heel is raised and this one-way rotating clutch ratchet, so that when the heel is lowered, no load is applied or the load can be reduced. In addition, when the foot is stepped forward in a walking-like manner, it is easy to lower the heel to the ground first, and even when standing still on the spot, the heel can be easily lowered and the foot kept horizontal. And solved the above problems.

In addition, the present invention provides a drive mechanism from a drive plate to a wheel. This sports equipment has one or more one-way clutches and ratchets in the middle of the power transmission path. For example, in the places where the one-way rotating clutch perimeter can be attached, see the examples in Figs. 1 and 2, and in addition to the sprocket 8a in the figure, the rotating parts such as the sprockets 9a and 9b and the wheels 13 Are mentioned.

This drive mechanism can be combined with various one-way rotating clutches, ratchets, bearings, shafts, gears, belts, pulleys, chains, sprockets, cranks, springs, spiral springs, constant torque panels, etc.

In addition, as shown in 4a of Fig. 1 of the embodiment, an elastic body such as a spring is incorporated in the middle of the power transmission path from the shoe or the driving plate to the wheel, so that when the heel is raised or kicked. It can absorb and mitigate the impact transmitted to the feet and shoes, and reduce foot fatigue.

In addition, by attaching an elastic body such as a spring, air spring, spring spring, etc. between the drive plate and the body frame as shown in FIG. The force accumulated when lowering the heel in this elastic body acts as a driving assist force, and the driving plate can be raised lightly. The ability to raise the drive plate lightly can enhance the kicking action.

The elastic body that generates the driving assisting force has a shape that can be adjusted to any strength.

In addition, the front wheel or the rear wheel can be moved up and down with respect to the main body frame, and a mechanism that can adjust the balance of up and down movement by an elastic body such as a plate panel, a spring, an air spring, and a mainspring panel is provided. When the foot is carried forward, the toes no longer float and stabilize, providing good directional stability, making it easier to lower the heels and lift the feet horizontally, The operation at the time of traveling can be performed smoothly.

By making the body frame extendable back and forth, the running stability when extended can be increased.

In this method of extending the main frame, the shape of the main frame is attached between the wheels, or the shape of the auxiliary wheel is attached to the front or rear to prevent deformation of the main frame due to weight. However, it can be used as a long and stable sports equipment.

In the case of a drive mechanism that generates driving force by reciprocating the chain or belt as shown in Figs. 1 and 2 of the embodiment, the force is used to return the chain or belt pulled by raising the heel. As shown in Fig. 1 (7c in Fig. 1), by incorporating a constant current panel and a constant torque panel, it is possible to reduce the size and weight while absorbing the elongation during use of chains and belts, which may cause slack. There is no advantage.

Furthermore, as shown in 2c in Fig. 1 of the embodiment, by attaching an elastic body or a bending member around the thumb hill, it becomes possible to concentrate the kicking force on the thumb hill portion during the kicking operation, and the walking motion Above all, you can kick strongly using the snap of the ankle.

Also, by incorporating a brake mechanism and pressing the knee, or by using a shape that can be operated with a lever, handle, push button, etc. near the hand and the west, safety was dramatically improved, and the brake was applied. By making the shape that can be licked in the state, it is possible to stop the rotation of the wheel and at the same time prevent the drive plate from rising, so when mounting on the foot, when standing still on the spot, walk without rolling the wheel At times, operations such as going up and down stairs become easier.

In addition, the safety is dramatically improved by using the stock together, and the danger of falling is reduced and stable driving can be performed. Furthermore, by making the stock expandable and contractable or removable, it becomes excellent in portability and storage.

In addition, the displacement angle of the drive plate, which changes due to the heel raising or kicking motion, is detected by a sensor such as a potentiometer, and another drive source such as a motor or solenoid is controlled and linked to the kicking motion. It can be used as an assist for human power.

Also, the number of wheels can be as large as one or more for each of the front and rear.

Also, the driving wheels can be front, rear or other wheels and wheels of infinite orbit.

In addition, the use of a swivel wheel, forward or backward, allows for smooth turning during exercise.

By using a generator or a generator-type motor as a part of the drive mechanism, power can be generated while the vehicle is running, and warning sounds and warning lights can be generated to improve safety.

If another drive source is used together, separate the power supply and controller from the frame, hold it separately as a waste belt type, shoulder type, etc., and supply electricity from one power source to the two frames on the left and right In addition, by controlling two frames with one controller, the weight of the entire frame at the foot can be reduced.

In addition, when using another drive source together, a remote control using weak radio waves or infrared rays can be used to operate two feet with one remote control. The advantage of this is that the power is easily turned on and off, and the control is easy to operate. BRIEF DESCRIPTION OF THE FIGURES

The present invention relates to a sports equipment that rolls and moves by a wheel, such as a roller skate or an inline skate, in which two sports shoes are mounted on one foot with two feet each having the following drive mechanism. It is a thing. It has a plate integrated with the shoe or a plate to which the shoe can be fixed, and this plate is connected to the body frame supporting the wheel at the front of the shoe as a drive plate, and has a shape that allows the heel to be raised and lowered. By raising the heel or kicking the drive plate from the body frame, it generates a rotational force that accelerates the rotation of the wheels, and uses this rotational force as the driving force. The drive mechanism uses a specific point as the point at which the rotational force generated by the heel-lifting and kicking operations is synchronized with the rotation of the wheel, and performs the heel-up and kicking operations more continuously at this specific point. By doing so, it is a mechanism that can kick the ground without kicking feet flowing backward even while rolling, and is a sports equipment with this drive mechanism.

An example of the embodiment will be described with reference to FIGS. 1 and 2. First, FIG. 1 is a side view, and FIG. 2 is a plan view of FIG. This is an example of driving the rear wheels with two wheels at the front and rear, showing the basic functions. In FIG. 1, assume that drive plates 2a, 2b, and 2c allow the shoes 1 to be attached and detached. The drive plates 2a, 2b, and 2c are of an integral type, and 2c is bendable using a flexible material. The drive plate 2a is connected to the main frame 3a at the shaft 6a, and is movable up to about 30 degrees with respect to the main frame 3a about the shaft 6a. By these, the heel of the drive plate 2b The part has a structure that allows it to move freely up and down, and a structure that allows the heel to be raised and kicked at the thumb hill.

The driving hardware 5 is also connected to the body frame 3a at the shaft 6a, and has a structure in which the driving hardware 5 moves up and down around the shaft 6a. A guide bin 4b that supports the spring 4a and passes through the drive plate 2b is fixed to the drive hardware 5. When the drive plate 2b moves up and down by the guide bin 4b and the spring 4a, the drive hardware 5 moves up and down in cooperation, and by raising the heel, the drive hardware 5 is also lifted via the spring 4a. It is done. In the event of a collision, the spring 4a also serves to absorb the shock. The spring 4a has a structure in which the strength can be adjusted by the guide pin 4b.

The driving hardware 5 has a shape in which a force is applied by a force of a spring 11a attached to the shaft 6a so as to be lifted from the main body frame 3a around the shaft 6a. The strength of the spring 11a can be freely adjusted by the spring retainer 12a. As a result, by lowering the heel, the driving hardware 5 is pushed down by the main body frame 3a, and the spring 11a is compressed and the force is stored. By raising the heel, the driving hardware 5 is compressed, and is lifted from the main body frame 3a by the repulsive force of the spring 11a in which the force is stored.

A chain 7a is connected to the drive hardware 5, and when the drive hardware 5 is lifted, the chain 7a is pulled and the sprocket 8a with a built-in one-way rotation clutch centering on the shaft 6b rotates. The chain 7a is guided by an idler sprocket 8b, and is connected to a constant torque spring panel 7c and hardware 7b. When the driving hardware 5 is pushed down, the constant torque spring 7c works to pull back the chain 7a. The reciprocating motion of this chain 7a makes it possible to 1864

The 14 kets 8a rotate intermittently. With this alternate rotation, the shaft 6b is intermittently rotated in one direction.

A sprocket 9a is attached to the shaft 6b, and a sprocket 9b and wheels 13 are attached to the shaft 6c. The rotation of the shaft 6b is transmitted from the sprocket 9a to the sprocket 9b via the chain 7d, and rotates the shaft 6c and the wheel 13.

A brake disk 15 is attached to the shaft 6c, and the brake 16 is extended by a wire 17 and can be operated at hand. At the hand operation part, a lever 18a is attached to a telescopic stock 19, and the brake 16 is actuated by gripping this lever 18a, and the disc 15 is sandwiched to operate the brake. By applying the band 20 to the lever 18a with this brake applied, the brake can be kept applied.

Further, a shaft 6e is attached to the main body frame 3a, and a front wheel frame 3b which is movable up and down around the shaft 6e is attached. A wheel 14 is attached to the front wheel frame 3b around a shaft 6d. A spring lib is attached to the shaft 6e, and the force acts to lower the front wheel frame 3b from the body frame 3a around the shaft 6e. The body frame 3a and the front wheel frame 3b have a structure integrated by putting weight on them. The strength of this spring lib can be freely adjusted by the spring holder 12b. Further, also _c Split ring 11c is also useful to suppress the impact between the body frame 3a and the front wheel frame 3b, in each Schaff bets a structure bearing 10 is mounted.

The operation of the first embodiment of the present invention will be described with reference to the drawings.In FIGS. 1 and 2, the drive plate 2b vertically moves about the shaft 6a by the movement of raising and lowering the heel of the shoe 1. . This movement is sprocketed from drive plate 2Tb. Picture 2/11864

15 Transmitted to the drive hardware 5 via the ring 4a. Since the drive hardware 5 is connected to the chain 7a, when the drive hardware 5 moves upward by the heel-up motion, the chain 7a is pulled and the sprocket 8a with a built-in one-way rotation clutch is moved. Rotate. At this time, the one-way rotating clutch works to rotate the shaft 6b. This is the forward rotation of sprocket 8a. Next, when the driving hardware 5 is lowered, the force of the chain 7a that has been pulled is released, and the chain 7a is returned to its original state by the constant torque spring 7c. At this time, the sprocket 8a having a built-in one-way rotation clutch idles with respect to the shaft 6b. This is the reverse rotation of sprocket 8a. The rotation of the shaft 6b is transmitted to the wheel 13 as it is, and the shaft 6b and the wheel 13 always rotate in synchronization.

Here, assuming that the wheel 6 is rolling and moving, the shaft 6b is rotating according to the speed at which the wheel 6 is moving. When the sprocket 8a with a built-in one-way rotation clutch tries to rotate forward at a speed higher than this rotation speed, the rotation of the shaft 6b is synchronized with the sprocket 8a and is subjected to a force to accelerate. The point at which this rotational speed is synchronized is set as a specific point, and the heel is strongly lifted at this specific point and a strong kicking operation is performed with the foot, whereby the shaft 6b is accelerated and the wheel 13 is also accelerated. In other words, the rolling motion of the wheel produces continuous acceleration according to the kicking force, which is a weak point of the conventional technology.When kicking, the foot and wheel are always stopped with respect to the ground, Or, the feet do not flow backwards.

At a particular point, this heel-up and kicking attempt will cause wheel 13 to rotate. At the same time, the body frame 3a is pushed rearward by the heel raising and kicking operations, so that the wheel 13 receives the force of reverse rotation due to friction with the ground, and attempts to lower the drive plate 2b and the drive hardware 5. Power It is also a form that repels heel raising and kicking. Simultaneously, the heel is lifted and kicked with a stronger force to suppress the reverse rotation of the wheel 13, thereby allowing the ripper to kick without flowing backward, thereby accelerating the forward movement. It is.

At this time, it is effective to provide an elastic body such as a spring 4a in the middle of the transmission of power from the drive plate 2b to the wheel 13 so that the force applied to the heel raising operation and the vibration of the wheel 13 do not cause an impact. is there. When lowering the heel, the sprocket 8a rotates in the reverse direction, so the only load is the force to compress the spring 11a. The compression force of this spring 11a can be adjusted according to the weight and physical strength, and can be used comfortably. Also, before reaching a specific point, the rotation speed of the sprocket 8a having a built-in one-way rotation clutch is lower than the rotation speed of the shaft 6b, and is rotating so as to follow the shaft 6b. Even in such a case, if there is no large difference in the rotation speed, the forward rotation of the sprocket 8a and the rotation of the shaft 6b will be synchronized when the stairs flow backward by the difference, so it is also a specific point. You can kick with your toes.

Also, when the heel is lowered, the spring 11a is compressed and stored as a force when the heel is lowered, and when the heel is raised, the repulsion of this compressed force is used to raise the heel raising force, drive plate 2b, and drive hardware 5. It can be used as an auxiliary force to raise.

It should be noted here that the movement of the kicking foot in the walking movement is a complex movement of raising the heel, stretching the ankle, falling forward, and kicking with the tip of the foot That is. When walking, he kicks with one foot and at the same time moves his weight to the other foot, which he alternates left and right. Due to this combined movement of the kicker's foot, the movement of raising the heel attempts to rotate the wheel 13 and, at the same time, can be kicked with the tip of the foot. 02 11864

17

In addition, when walking, it is natural for a foot that steps forward to be lifted off the ground as if to lift its foot, and then to reach the ground from the heel. In this case, the toe wheel 14 on the side that steps forward is easy to separate from the ground, the toe fluctuates when it comes to the ground from the heel, and the toe wheel 14 is turned in a direction different from the direction in which it has proceeded. It may become unstable due to contact with the ground or adjustment of the spring 11a. In order not to create such a situation, and to be able to walk stably, the front wheel frame 3b with the shaft 6e as the axis and the wheel 14 attached should move at an angle of about 60 degrees from the body frame 3a. It was done. Spring llb and 11c were attached between the main body frame 3a and the front wheel frame 3b to make it move with elasticity, so that a smooth walking motion could be performed.

In addition, the use of stock and brakes makes it easy to put on and take off this sporting equipment, stand still, stand up, stop running, walk without rolling the wheels, and climb up and down stairs. This made it easy to do.

In this way, the sporting equipment has little or no backlash, so it can be used effectively with less energy wasted, and it can be used safely and comfortably for long periods of walking. You can do it.

By increasing the speed of raising and lowering the heel and increasing the power transmission ratio to the wheel, it is possible to accelerate faster even when the wheel 13 is rotating. You can kick hard.

If the walking speed of an adult is 3.6 km Z, it will be lmZ seconds. When accelerating above this speed, kick the wheel 13 at a peripheral speed close to lmZ seconds. We can accelerate to 18. By repeating this, the sports equipment can be used by accelerating to a moderately fast speed according to the physical strength of each person using the equipment.

Here, by selecting the type, size, number, and material of each part, it is possible to make a selection according to the physical strength and preference of each person who uses this sports equipment. Of course, it is possible to use gears and belts other than the chain sprocket to drive or change gears.

A second example of the embodiment will be described with reference to FIGS. 3 and 4. First, FIG. 3 is a side view, and FIG. 4 is a plan view of FIG. This differs from the basic functions shown in Figs. 1 and 2 in the first example in that the shaft 6e, the front wheel frame 3b and the idler 8b are omitted, the shaft 6d and the wheel 14 are attached to the body frame 3a, and another drive This is an example of incorporating them so that they can be used together.

In this mechanism that uses another drive source, the sensor 21, the servo motor 22, the controller 23, the power supply 24, the signal cable 25, the switch 26, and the adjustment switch 27 are placed in the positions shown in Figs. Fix to the body frame 3a and the stock 19 with screws.

The sensor 21 has a structure that can detect the displacement angle of the drive plate 2b. In addition, a sprocket 8c, a chain 7e, and a sprocket 8d with a built-in one-way rotation clutch are added to transmit power from the servo motor 22 to the shaft 6b. The switch 26 is a switch for turning off the thermo-motor 22 when the brake 16 is operated by grasping the lever 18a. The switch 27 is a switch capable of turning on / off the power of the servo motor 22 as another drive source and its control system and adjusting the rotation speed.

This is an invention that uses the movement of time to assist the acceleration of the rotation of the wheel, making it easy to move and accelerate. This sports equipment is an extension of walking 1864

20 Anyone can easily use it and can climb and accelerate on gentle hills, so everyone can enjoy it as a convenient cycling tool instead of a bicycle when going to a vacation spot with family or friends. Because it is small, it can be put in the trunk of a car for everyone. This is expected to increase the sports population and increase the number of healthy people.

The invention also finds application as a vehicle to replace a short distance bicycle. If a structure incorporating safety into the present invention is used, it can be used as a foot for commuting or going to school, from home to a company or school, or from home to a station. The advantage is that the storage area is not bulky like a bicycle, especially because it is a compact.If it is stored in a coin locker, there is a possibility that a large bicycle parking area in front of the station and abandoned bicycles will be reduced, and modern storage is possible. This is an invention that has the potential to solve the major problem of station-side bicycles. This has the potential to create new industries, such as the addition and management of new coin lockers and the improvement of the station environment. If used as a substitute for a bicycle, it can be stored in a small space, such as indoors, at home without leaving it in the garden or on the road like a bicycle. By highly utilizing this invention, it is expected that a new industry will be created in society and the social environment will be completely changed.
