Abstract

[Problem] The mechanisms of conventional vehicle traffic blockers and the like that are installed at exits of one-way street roads and exits of highways employ computers using images, sensors, etc., and require electricity for indicators and acoustic warnings and for the operation of crossing gates, etc. Meanwhile, wrong-way travel preventing roller type mechanisms which do not use electricity are unsafe since being unable to put a brake on a vehicle moving forward can be hazardous. Furthermore, warnings may be ignored and mechanical-type wrong-way travel preventing mechanisms etc., may be forcefully defeated. [Solution] As shown as 3A in figure 3, D-shaped-roller rows 102R which are laid parallel to each other at intervals are arranged sequentially so as to intersect with the approach direction of a wheel 01 of a wrong-way travelling moving body in such a manner as to form an upward slope for the wheel 01. When the wheel 01 moves in the wrong way in direction 003 and reaches the upward slope of the roller rows 102R, the roller rows 102R start spinning, thereby making it impossible for the wrong-way travelling moving body to go forward any further. At that moment, vibration is generated so as to notify the driver of an anomaly, making it is possible to safely back up the moving body. On the other hand, the moving body has no problem moving forward or applying a brake, and generates less noise during transition on the flat portion of the roller rows 102R.

Description

Mobile blockers and restraints

The present invention relates to the prevention of reverse running from a one-way road exit or a moving body, or the restraining of a moving body entering a specific place.

Conventional intruder-moving object prevention technology combines sensors and computers, issues warnings by image recognition, etc., draws noticeable signs on the road surface to call attention, and has different inclination angles of the road surface in the forward and reverse directions When bumps and protrusions were arranged and the vehicle traveled in the opposite direction, there were cases in which the shock caused by the steps caused the driver to feel abnormal.

However, because of the necessity of passing safely in the forward direction, all of them only issue warnings, require electric power, and those who dare run backwards can get over obstacles of boards and projections There were many things that forgave it.

In the case of a roller with a built-in non-return ratchet, it is possible to prevent intrusion by rotating the wheels of the reverse running mobile, but when the mobile is traveling in the forward direction, pressing the brake on the roller causes the roller to idle By doing so, the wheels were in the same state as the slip, and it was dangerous especially during traffic jams.

China Application No. 201210106097 Publication No. 10260528 JP-A-2017-066682 JP-A-2017-96028 JP-A-2017-107559

Reverse vehicles on one-way streets can cause serious accidents, whether intentional or negligible. In particular, although there are many reverse runs due to the negligence of the elderly, it is difficult to prevent reverse runs only with a simple step or a signal or sign that warns the driver.

In the case of the non-return ratchet roller type described in Reference 1, even when the brake was applied in the forward direction, the roller idled and the brake did not work.

In addition, the one in which a computer is interposed as in Document 4 requires electricity, its structure is complicated including input and output, and the risk of failure and frequent maintenance are required. Also, the method of displaying a warning has no physical deterrent.

In addition, it is difficult to completely block traffic with a movable physical projection on the road surface as described in Reference 3, and if the intruder has a strong intention to intrude, such as terrorism, the vehicle must be prevented from entering. Is completely difficult.

Also, it is possible to try to re-enter the vehicle by restraining the invading vehicle in the specific area, and from the apparent appearance, if it enters, it will be stuck and the vehicle may be damaged. Although barricades can be expected to be avoided naturally, it is possible to search for another intrudable place and try again, so it is necessary to restrain such vehicles on the spot and deprive them of their freedom It is.

Therefore, based on the problem, it is possible to use a device that does not use electric power, has a simple and durable structure, and allows a moving object to pass safely in the forward direction, but does not physically allow the intruding moving object to pass. Or, we devised a wheel restraint that restrains an intruding moving object.

For example, on a muddy road or a snowy road, a state in which a vehicle wheel slips due to a significant reduction in friction with a road surface in contact with the wheel due to mud, snow, ice, or the like so that the vehicle does not remain forward or retreat is referred to as a stuck. In particular, it is difficult to climb the slope in this state.
In the present invention, a state close to this is insulated from the friction between the wheel and the road surface by a plurality of rollers, thereby depriving the moving body of thrust and freedom of steering, thereby preventing the invading moving body.

(Roller height)
According to the present invention, a freely rotatable roller is disposed so as to be able to contact a wheel (drive wheel) of a moving body, to eliminate contact friction with a road surface, and to increase the height of the roller in the traveling direction of the moving body. By providing a portion that sequentially raises the height, the roller that touches the wheel idles, loses its foothold due to the friction of the wheel (drive wheel), and effectively creates a state in which the wheel slips on the spot, and advances the moving body Block.

(Roller height and movable arrangement)
The following describes a moving object traffic blocker that is arranged or movable so that a difference occurs in the vertical height of a portion where at least two or more rollers can come into contact with the wheels of the moving object. explain.

The means is arranged on the road surface where the reverse running vehicle is desired to be prevented, intersects with the rotation axis of the wheels of the reverse running vehicle parallel to or perpendicular to the road surface, crosses the approach direction of the wheels of the reverse running vehicle, Out of a plurality of roller rows each having a freely rotatable rotation axis, the outer peripheral portions of at least two or more of the roller rows can come into contact with the wheels of the reverse moving body and move in the direction in which the reverse vehicle travels. The height of at least the second and subsequent roller rows of the plurality of rollers is higher than the height of the preceding roller row, or at least one of the plurality of rollers as shown in FIG. 5B or FIG. One or more of the reverse running moving bodies have a mechanism in which the rotation axis of the rear roller moves compared to the roller on the front side and a difference occurs in the height of the rollers. Can stop moving objects.

That is, when there is a difference in the relative height of at least two rollers that are arranged in parallel, in a direction intersecting with the wheel, and intersect also in the vertical direction, and only the roller is touching the wheel, Of the rollers, the wheel cannot travel in a higher roller direction, and the roller that contacts the wheel idles, so that the rotation of the wheel should occur due to friction with a ground contact surface. Can take away the propulsion of

In particular, the height of the rollers is gradually increased in the vertical direction (plumb line) as the vehicle moves in the direction to be propelled by the wheels of the moving body, so that it is extremely difficult for the wheels to pass through the rollers. become.

(Slope roller)
Further, since it is sufficient that the height of the rollers is gradually increased as the wheels advance, if the road surface on which the wheels of the moving body are to contact the ground is a slope, along the slope, the slope direction of the slope. Even if rollers are provided and are arranged in parallel with each other so as to intersect with the traveling direction of the road surface, the height of the rollers will be increased gradually, and the effect of inhibiting the moving body will be exhibited in the same manner as described above.

When the wheel on the lower roller crosses the next contacting higher roller, the wheel kicks off the lower roller and advances, contacting the lower roller with the higher roller. The wheels cannot move forward unless they switch to contact with the roller. However, since the lower roller and the higher roller that are in contact with the wheel both rotate freely, the wheel cannot be used as a foothold for advancing. Therefore, the propulsive force generated by the moment of the wheels is lost by the rollers and cannot be advanced.

(Uneven roller)
A general roller (equal roller) is one in which the cross section of the surface perpendicular to the rotation axis is a perfect circle, and the rotation axis passes through the center of the perfect circle, but the non-uniform roller used in the present application will be described. I do.
The non-uniform roller in the present application refers to a roller including an eccentric roller in which a distance between a rotation axis of the roller and an outer peripheral portion of the roller that can contact a wheel (drive wheel) of a moving body is not equal.

Further, if a roller having an eccentric rotation axis or an uneven roller having an elliptical, polygonal or irregular cross-sectional shape is used, the weight due to the weight of the moving body and the wheels may be applied to the uneven roller compared to the uniform roller. This causes uneven rotation resistance in the rotation of the uneven roller, but the moment at which the uneven roller can rotate is smaller than the traveling moment of the driving wheels of the moving body.

In addition, since the uneven roller which is stepped on by the weight of the moving body and the wheels hardly rotates, that is, a rotational resistance occurs, and unlike the case of the uniform roller due to the brake, the uneven roller generates a constant resistance. The brake is activated.

(Uneven roller and height)
For example, the wheel of a moving object that enters in reverse from a one-way exit,
When the height of the roller enters a group of rollers that are sequentially increasing in the vertical direction, the height of a plurality of rollers that can contact the wheel (drive wheel) gradually increases as the wheel of the moving body advances. By going, the only foothold to get over them is the roller, and even if the roller is an uneven roller, the uneven roller has resistance when rotating in a state where a load is applied in the vertical direction. When they exceed a certain moment, they idle and consequently the wheels begin to slip in place, the intruding vehicle cannot move forward and consumes the thrust of the wheels by the uneven rollers.

The driving wheel of the moving body cannot go to the height of the higher uneven roller unless the lower uneven roller has a rotational resistance exceeding the moment by the driving wheel of the moving body,
Even if there is sufficient rotational resistance on the rotation axis of the lower roller, the non-uniform roller having the rotation axis of the next higher roller may be used unless there is a similar rotation resistance on the rotation axis of the next higher roller. You cannot exceed it.

(Roller movement)
Also, each axis of one or more of the plurality of roller rows, including the uniform roller and the non-uniform roller, is also movable in a height direction, and a relative height between the roller rows is adjusted. The means of moving the rollers may be different.
As the wheels of the moving body enter the roller group,
The rotational force of the wheel of the moving body, the weight of the moving body and the wheel, the moving force of the moving body, a chain, a wire, a lever, a spring, a gear, used alone or in combination, and further using electromagnetic force Power and hydraulic pressure may be used.

(Restraint)
For the purpose of preventing the intruding moving body of the present invention and further restraining the intruding moving body, it is possible to surround a part of the outer peripheral portion of the wheel of the invading moving body so as to be able to contact, and is parallel to the wheel rotation axis. Two or more rollers having an axis, each roller that can freely rotate can also move in the height direction, and its position is maintained after the movement, the wheels are used by the rollers on the road surface. Insulated from contact,
Originally, the wheels (drive wheels) were brought into contact with the road surface, so that the friction of the wheels did not generate the thrust of the intruding moving body, and a state in which the vehicle could not move forward or backward was obtained.

(Constrainer turntable)
The rotation axis of the roller group and the rotation axis of the wheel of the intrusion moving body are parallel to the roller group for the purpose of preventing or restraining the intrusion moving body, or the rotation axis of the roller group and the rotation axis of the wheel of the intrusion movement body. It is desirable that the approach direction is a right angle, but in reality, the intruding moving body to be restrained does not always enter the rotation angle of the roller group exactly at a right angle, and between the wheel and the axis of the roller. Angle twist can occur.

Therefore, a part or all of the roller group for the purpose of preventing or restraining the intruding moving body is placed on a turntable, and the wheels of the intruding moving body are stepped on the roller group on the turntable. A plurality of rollers that are individually rotatable freely in the axial direction of the roller row stepped on by the wheels above are rotated at individual speeds and directions, whereby the twist of the approach angle is transmitted to the turntable, By rotating the turntable, the torsion is eliminated and, at the same time, the approach angle is corrected.

At this time, the turntable must be able to rotate freely, and the axis of rotation of the roller that the wheel of the intruding mobile should first step on should be in a direction that is almost perpendicular to the direction in which the intruding mobile enters. In general, an elastic body such as a spring is used to direct the light in a certain direction.

However, if the plurality of rollers on the turntable are rotated in the direction of the wheels of the invading moving body so that the plurality of rollers are aligned at the stage when the invading moving body steps on the rollers, the elasticity of the spring becomes a resistance and becomes an obstacle. .

Therefore, the balance between the rotation axis of the turntable and the turntable is decentered so that the "roller portion on which the wheels of the intruding moving body should be first stepped" becomes heavy, and the turntable using gravity is used. Can be determined in a specific direction, and at the same time, the approach angle of the intruding moving body can be corrected.
In addition, the mechanism of the turntable of the present application may be used for a moving object blocking device.

(Deceleration assistance)
In order to achieve a more reliable intrusion prevention effect or restraint effect of the present invention, the wheel of the moving body has a rotation axis in a direction intersecting with the moving body approaching direction on a road surface before stepping on the moving body preventer. Either disposing a plurality of the roller groups, disposing one or more deceleration load bumps before passing through the moving object blocker, or stopping the moving object at any place immediately before and after a curve of a road. By arranging the container or the restraint, the moving body can be decelerated.
Further, the arrangement of the moving object stoppers may be repeated depending on the height of the rollers, and the arrangement of the heights of the rollers in the moving object stoppers may be arranged in a pattern such as a step-like shape, a sawtooth shape, or a waveform.

In addition, the roller group for the purpose of blocking and restricting the moving body does not have to be particularly fixed to the road surface. If the driving wheels are constrained, it is impossible to move forward further, and even with a 4WD or RF vehicle, the freedom of steering is lost and the rollers not fixed to the road surface cause the wheels of the moving body to rotate. By being integrated with the wheel while being restrained, the front wheel becomes equal to or more than the locked brake, so that a large restraining force still remains.

(Definition)
Terms in this application are defined below.
The moving body referred to in the present application refers to a moving body having a plurality of wheels (tires or the like), any one of which is a driving wheel, which can be moved by the moving body itself.

In the present application, the wheel in the reverse movement preventing use moving object traffic blocker refers to a driving wheel of the moving object, and the wheel in the moving object restraining application is not limited to the driving wheel of the moving object.

In the present application, for example, as shown in 101 to 111 of FIG. 4, the cross-sectional shape of the surface perpendicular to the rotation axis direction of the roller is a polygon, an ellipse, a combination of a straight line and a curve, an irregular shape, or the like. Regardless of where the rotation axis is set in the shape, it is assumed that the distance between the roller rotation axis and the outer peripheral portion of the roller that can contact the wheel of the moving body is uneven, and that the roller is perpendicular to the rotation axis direction of the roller. Even if the cross-section of the surface is a perfect circle having a center, the distance between the roller outer peripheral portion and the roller rotation shaft that can be in contact with the wheel of the moving body including a case where the rotation axis does not pass through the center (eccentricity) Are called "unequal rollers" or "unequal rollers".

In the present application, a general roller in which a cross section of a plane perpendicular to the rotation axis is a perfect circle and the center of the perfect circle is a rotation axis is a “uniform roller” or “a uniform roller”. This is distinguished from the above-mentioned "uneven roller". Further, when simply referred to as “roller”, it refers to a roller including both “even roller” and “unequal roller”.

In the present application, a plurality of individually rotatable rollers having a rotation axis on an extension of one rotation axis are referred to as “roller rows”. Further, as shown in FIG. 8, a plurality of composite rollers in which one or more rollers are arranged in a frame having a rotation axis have a plurality of roller rows forming a position having a rotation axis on an extension of a common rotation axis. May then be moved from that location to another location. A group in which a plurality of roller rows are mechanically connected to each other is referred to as a “roller group”.

The roller rows described in the present application should be arranged at intervals and should not interfere with each other, but if some of the rollers are movably arranged, for example, they are arranged on composite rollers, wheel restraint frames or tension arms, etc. Depending on the position of the moved roller, the rollers may interfere with each other.

The `` composite roller '' referred to in the present application means that the rotation axes of a plurality of roller rows are arranged in parallel with each other, and the plurality of roller rows are such that individual rollers can rotate on respective rotation axes. The specific one or more roller rows are arranged in a frame that relatively restrains the positional relationship with a pivot axis set at a specific position parallel to the rotation axis, and as a result, the specific one or more roller rows It means that the vertical height of a row changes.

The “wheel restraint frame” referred to in the present application means that a part of the outer peripheral portion of the wheel is sandwiched between a specific roller row and one or more other specific roller rows in the plurality of roller rows in the moving body restrainer. A frame and the roller row, which are moved or arranged in such a position and have a structure for maintaining the positional relationship, by physically insulating wheels from ground friction caused by friction with a road surface, a moving body. The wheel restraining frame is included in the composite wheel.

`` Roller height '' in this application means that the wheels of the moving body can be contacted, regardless of the diameter of the roller and the position of the rotation axis of the roller, unless otherwise specified. Refers to the vertical height of any part. Therefore, the height of a roller in which the distance between the rotation axis of the roller and the outer peripheral portion is not equal, that is, the “uneven roller”, changes depending on the rotation angle.

Therefore, “high” and “low” between the rollers are relative comparisons of the vertical height of a portion of the outer peripheral portion of the roller that can contact the wheel of the moving body.

In the present application, the description is mainly made of “an eccentric roller” and “a roller in which a part of the cylindrical shape of the uniform roller is cut by a plane parallel to the rotation axis of the uniform roller = D-type roller”. In place of the roller having the above-described shape, a roller having a non-uniform distance between the rotation axis and the outer peripheral portion other than 100 as an example shown in FIG. 4 may be used, or a uniform roller may be included in a part of the roller. good.
Furthermore, the shape of the meridional section perpendicular to the axis of the roller, which is in contact with the bearing with the rotating shaft, does not have to be a perfect circle, and in this case, the distance between the outer peripheral portion and the roller rotating shaft is not uniform.

The turntable in the present application refers to a member in which a plurality of roller members and the like are arranged on a member having a pivotable upward turning shaft when the movable body restraint is installed on a road.

The “perpendicular meridional section” in the present application is a section cut by a plane perpendicular to the axis of rotation.

In this application, the term “moving object blocking device” and “moving object restraining device” refer to a mechanism including a roller group composed of a plurality of roller rows.

Some of the rollers arranged in the moving object blocking device according to the present invention may be arranged such that rollers having the same shape are spaced apart from each other by a rotation axis having the same vertical height. That is, there may be a portion where rollers of the same height are arranged.

What is shown in the drawings of the present application is merely an example for explaining the purpose of the application, and is for the purpose of deepening the understanding, and the content of the right is not limited to the drawings.

In the moving object blocker according to the present invention, the vehicle can pass through the one-way road in the forward direction without any problem, and in this case, the brake can be used. I do.
At this time, the vibration can make the driver feel an abnormality and give a warning, and if the driver who notices the reverse intrusion attempts to back, it becomes possible. This is a very important function for safely passing the moving object in the forward direction.

(Uneven roller)
The advantage of using a “roller having an uneven distance between the rotating shaft and the outer peripheral portion = a non-uniform roller” including a roller having a cross section of a perfect circle having an eccentric rotating shaft will be described below.
A uniform circle with a closed cross section of rollers, with a rotation axis at the center, and a plurality of evenly rotatable equal roller rows lined up in parallel at the same height. When an object is loaded, the load resistance is low, so it does not stop easily, and the same applies to the wheels of the moving body.

However, in place of the uniform roller, a "roller group having an uneven distance between the shaft and the outer peripheral portion" is disposed and a moving heavy object having inertia is placed thereon as described above. A part of the “uneven roller group” comes into contact with the moving weight, and the friction causes the angular velocity and load resistance of the roller rotating on the shaft to change periodically. At this time, the heavy object is moved up and down by a width corresponding to the distance between the heavy object in contact with the outer peripheral portion and the rotation axis of the roller. At this time, the vertical movement also consumes the inertia of the heavy object and contributes to the deceleration of the heavy object.

The same applies when this heavy object is replaced with a moving object such as a car with wheels, and the deceleration effect of the vehicle itself and the moment of the drive wheels of the moving object are reduced by the fact that the wheels do not come into contact with the road surface, and the thrust of the wheels is reduced. Can be expected not to be transmitted to the road surface, and the vibration caused by the roller having an unequal distance between the rotating shaft and the outer peripheral portion can draw attention to the driver of the moving body, or can transmit an abnormality to the driver.

In addition, if the driver of the moving body notices reverse running from the above situation and tries to get out of these roller groups with a back, if the speed is slow, the eccentric roller does not run idle, so it comes out of the eccentric roller group. Things are possible.

(Brake can be used)
As described in Reference 1, an intruding moving body that enters one-way from the opposite direction into the area covered with rollers with a ratchet mechanism is applied to the drive wheel in the forward direction by a ratchet mechanism. Rollers do not idle and exhibit the same friction as ordinary road surfaces, and there are methods of reverse vehicles that idle their driving wheels to prevent intrusion, but in this method, a moving body moving in the forward direction Depressing the brake on the ratchet roller is very dangerous because the wheel does not grip the ratchet roller and slips.

However, in the case of the uniform roller group, the brakes do not work because the rollers of the roller group idle, and the wheels of the moving body slide on the rollers while being locked, so the arrangement of the uniform rollers in the moving direction of the moving body. Should be as short as possible.However, when the forward traveling mobile body passes through the uneven roller group, it does not hinder the passage, and if the brake is applied on the uneven roller group, the Due to the rotational resistance of the uniform roller, friction occurs between the wheel and the uneven roller, so that a braking effect is obtained.

(Continuity of rotation resistance)
In addition, since the uneven roller is rotatable by a rotating wheel in contact with it and the rotational resistance of the uneven roller is not due to the frictional resistance of the rotating shaft of the roller, even if the roller is operated for a long time, its sectional shape and shaft As long as the state does not change, the resistance remains the same.

(Simplicity of mechanism)
In the case of preventing reverse vehicles that try to invade from the exit of the expressway, the probability of failures increases for complicated structures and mechanisms that require frequent maintenance, and the maintenance of the expressway is safe and uninterrupted. Although this may have a significant effect on operation, the present invention using "rollers with different heights and an uneven distance between the shaft and the outer periphery" can be constructed with simple moving parts with a minimum structure. Therefore, the function can be maintained for a long time with high reliability.

Further, in the moving body restrainer, the relative height between at least one or more movable rollers and another roller changes due to the intrusion of the wheel, and the movable body restrictor moves to a position surrounding a part of the wheel outer peripheral portion. I do.
Thereby, the frictional contact between the wheel and the road surface is eliminated, and the rotation and steering of the wheel are physically insulated from the road surface, so that the moving body is prevented from moving forward and backward, and the moving body itself can be restrained.

(D-type roller)
In the case of a roller (D-type roller) having a rotation axis at the center of the cylindrical roller and having a flat part in which a part of the outer peripheral part is cut in a plane parallel to the rotation axis, the flat part has a relationship with the center of gravity. Since they face upward, by arranging and arranging a plurality of them, there is almost no height difference between the rollers when they come into contact with the wheels, and in particular, the running noise of the moving body passing in the forward direction is reduced.

Further, even when a person steps on the D-type roller and walks, the D-type roller is unlikely to rotate, and an accident such as a pedestrian falling down due to unexpected rotation of the roller is unlikely to occur.

The structure is simple, so there are few troubles and there is little trouble in maintenance, etc.In addition, even if it breaks down, it is a hindrance that does not hinder forward traffic, and stops on the reverse drive prevention device during forward traffic The moving body that has moved can move forward again.

In addition, by placing a speed reduction load bump, or a similar group of rollers in front of the moving object traffic blocker or moving object restraint of the present application, or by arranging the roller group before or after a curve or in the middle thereof, The moving body is decelerated, and the blocking effect and the restraining effect of the present invention become more reliable.

(Material and shape of roller)
First, the material of the roller to be used in the backstop device of the present application will be described.
A sufficiently high-strength and lightweight material that does not deform or break even when subjected to the weight and wheel moments of the moving body that passes through, and the force in the moving direction of the moving body is required, and is used outdoors for a long time When used at the exit of a highway, etc., it does not deteriorate due to rust or the like when used in a vehicle. For example, the outer peripheral portion and the rotating shaft portion are made of stainless steel, and a composite material such as FRP or CFRP, a thinned stainless steel, or a high strength ceramic or the like may be partially or entirely used.

In addition, even if the shape of the roller is not a combination of a reinforcing structure in a cylindrical shape, a plate washer-like material molded in a plane cross-sectional shape perpendicular to the roller's rotation axis direction is rotated separately and alternately with the spacer. It may be arranged as possible.

In particular, in order to improve the braking performance of the forward moving body, the surface of the roller according to the present invention may be subjected to processing of unevenness having a large friction coefficient, application of a friction material, baking, or soft material and hard material (for example, , A soft material and a steel), or a roller made of a friction material itself.

The length of the roller in the rotation axis direction in the specification and drawings of the present application does not need to be one long roller for one axis. By arranging a plurality of rollers in a short axial direction, such as arranging them, the inertia of the roller unit is reduced, and the rotation responsiveness is improved.
In addition, the contact area between the roller and the bearing supporting the rotating shaft is small, and the shaft contact resistance can be reduced.

The arrangement interval of the rollers to be used in the present application has an outer peripheral portion capable of contacting the wheel of the moving object to be passed, but even if it can be contacted by a small-diameter wheel of a small moving object such as a light car, Depending on the position of the roller, there may be a roller having a roller outer peripheral portion that cannot contact a wheel of a large truck or the like.

In addition, there may be a plurality of rollers rotating on one material axis, and even if each roller rotates, it has a positional relationship that does not cause interference / collision with each other, and the weight of the moving body is added. Are also arranged on a bearing having a strength that does not hinder rotation.

The roller of the present application is intended to insulate the vehicle from contact with the road surface in contact with the wheels of the moving body. When the friction of the roller is reduced, there is a possibility that the moving body may skid or the like, and the wheel may separate from the roller. Therefore, it is better that the outer peripheral portion of the roller has friction with the wheel. For example, a roller having an uneven portion formed on the outer peripheral portion of the roller, or a member having a high friction material printed thereon may be used.

The roller member exemplified in the drawings of the present application is made of, for example, a lightened stainless steel material, and has an axial length of 10 to 20 mm and a maximum diameter of the roller of 20 to 100 mm on the same shaft. Although it is described with the drawings that rollers of the same dimensions are arranged at intervals from each other, in actuality, the present invention is not limited to the example of the present application, but also considers the application, use environment and strength, durability, wear resistance, and the like. Thus, the dimensions and materials of the members may be determined.

The length of a roller constituting a roller row is made smaller than the width of one wheel of an expected intruding moving body, and a checker pattern when viewed from above, or the rotation axis interval between adjacent roller rows is set to a radius of rotation of the roller. Closer, and may be a group of rollers arranged alternately so that adjacent rollers do not interfere with each other, whereby the height of the rollers constituting the group of rollers is continuous, so that there are fewer irregularities for the wheel. The running noise on the rollers can be reduced.

(Fig. 1)
In order to show the best mode of the present invention, a specific description will be given using examples shown in the drawings. In the first example, as shown in FIG. 1, the rotation axes of a plurality of roller rows 100R having the same diameter determined between, for example, 20 to 100 mm are parallel to each other and the plurality of roller rows move. Most of the plurality of roller rows 100R are arranged in a direction intersecting with the invasion direction of the body, and the height in the vertical direction of the surface that can contact the wheel 01 of the driving wheel of the intruding moving body continuously changes. Are installed on the road surface so as to form a slope for the wheels 01.
Here, when 01 enters from the 011 direction, the thrust of the moving body, which should be obtained by the friction between the wheels and the road surface, is consumed only by rotating the rollers by a plurality of 100Rs, and further, the higher the rollers in the vertical direction It is difficult to get over, and entry of the moving body can be prevented, but traffic from the forward direction 002 is possible.

(Fig. 2)
In the second example, as shown in FIG. 2, the rotation axes of the eccentric roller rows 101 </ b> R, on each of which a plurality of eccentric rollers 101 are arranged on the axis, are parallel to each other, and are arranged in a direction intersecting the direction of entry 001 of the moving object. Since the rotation axis of the roller is eccentric as in the roller row 101R, the roller in contact with the wheel requires a certain moment or more to start rotating, and as the roller rotates, the roller row 101R moves to the outer periphery of the wheel. The increase in the distance between the portion in contact with and the rotation axis of 101R raises the wheel and its moving body itself. That means that a part of the moving energy of the intruding moving body is consumed.

Further, some of the plurality of eccentric rollers 101 vibrate due to intermittent changes in the vertical height of a surface that can contact the wheel 01 of the intruding moving body, causing the driver to pay attention. The 101Rs arranged horizontally take off the acceleration of the wheels 01 due to their idling, and furthermore, since the plurality of 101R groups form a slope for 01, 01 passes over the plurality of eccentric rollers 101R. It is extremely difficult to do.

In the example of FIG. 2, an eccentric roller having a cross-sectional shape like 101 in FIG. 4 is described as an example, but the cross-sectional shape of the roller constituting the present invention on a surface perpendicular to the rotation axis direction is as follows. The roller is not necessarily required to be a perfect circle, and may be replaced with a roller having a cross-sectional shape as in the examples of 103 to 111 and having an uneven distance between the roller shaft and the outer peripheral portion of the roller. The cross-sectional shape of the surface perpendicular to the rotation axis of the roller is a state in which a part of a circle is cut out, that is, a D-type roller in which a part of a curved surface of a cylindrical roller is a flat portion, a polygon, an ellipse, The shape may be a polygon with a fillet or a contour formed by a closed curve. Further, the individual cross-sectional shapes constituting the plurality of roller groups do not need to be the same shape and the same diameter, and a plurality of types including a shape having a perfect circle and a rotation axis passing through the center of the perfect circle are mixed. May be.

(Fig. 3)
In the third example, a D-type roller having a flat portion at a part of the outer peripheral portion like the roller shape 102 shown in FIG. 4 may be used, and the shape will be described with reference to FIG. In particular, when there is a flat portion parallel to the rotation axis of the roller at a part of the outer peripheral portion of the roller like the roller row 102R, a certain amount of moment is required for a part of the roller 102R to start rotating. Then, as it rotates, the distance between the portion where 102R comes into contact with the wheel surface and the rotation axis of 102R increases, and the wheel of the intruding moving body and the moving body are lifted. That means that a part of the moving energy of the intruding moving body is consumed. Therefore, the horizontally arranged 102Rs take the acceleration moment of the wheels by the rotation.

Further, when the moving body traveling in the forward direction applies a brake on a part where the roller is flat, friction acts on the flat part, and even when the roller rotates, the same applies as described above. The movement energy is consumed, and the braking effect of the wheel and its moving body can be expected as compared with the case of the uniform roller.

When passing through the flat portion of the roller 102 without applying a brake in the forward direction (direction 004) and without particular acceleration, the 102 does not rotate, and the continuous flat portion of the roller 102 is significantly different from a road surface having no unevenness. There is no merit, so that there is an advantage that no loud noise is generated especially when it comes into contact with the wheels.

Further, unlike a normal roller having a circular cross section and the center of the circle as a rotation axis, a roller in which the distance between the roller rotation axis and the outer peripheral portion of the roller is not uniform does not easily rotate. Therefore, even if a person walks on a roller in which the distance between the plurality of roller rotation shafts and the outer periphery of the roller is uneven, the roller does not rotate carelessly, and an accident such as slipping and falling down occurs. This tendency is particularly strong in the case of 102 which is a D-shaped roller.

(5A in FIG. 5)
5A, which is a fourth example, is an example in which the rollers are arranged at the corners with a step. At the same time as the operation of the rollers, the rollers 101a arranged at the corners are wheeled. Attempting to get over the 101a on the scaffolding rollers is equivalent to slipping the rotation of the wheel relative to the road surface because all the rollers in contact with the wheel idle. Therefore, unless all the rotations of these rollers are fixed, the wheel cannot get over these rollers.

(5B in FIG. 5)
In 5B of FIG. 5 which is a fifth example, an eccentric roller 101b is disposed at the tip of the tension arm 10, and 4 is a 10 axis of rotation and 10 which can be moved to a position of 10a is a torsion spring 7 in FIG. It is arranged so that it may become the position of 10.
When the reverse moving body enters from the direction of 003 as in 5B, the wheels of the intruding moving body idle the rollers 101b arranged at 10 while stepping on the roller groups 101g to 101j, but 10 does not move, As described above, the intruding moving body cannot move forward.
In the case of a moving body entering from the forward direction 008, the user can push down the rising 10 at 7 and proceed in the 008 direction.
At this time, the wheel 10 can absorb the impact that the wheel receives due to the step by the force of 7, and by moving to the position 10a, the wheel can pass while reducing the impact by reducing the step.

(FIG. 6)
In FIG. 6, which is the sixth example, the eccentric rollers 101d to 101f are arranged on the composite roller 11 that can freely rotate on the rotation axis 4, and the eccentric roller prevents the reverse moving body from entering as in FIG. I can do things. Even if one of the rollers 101d to 101f is overwhelmed by the wheel of the reverse moving body, 11 rotates around 4 so that the wheel of the intruding moving body is arranged at 11 only by its own moment. It cannot exceed the set rollers 101d to 101f. The shock of the step received by the wheels of the moving body entering from the forward direction can be passed without any trouble while being reduced by the rotation of the wheel 11 with the movement of the wheels.

(sensor)
Vibration caused when a wheel enters a plurality of rollers with unequal distances between the rotating shaft and the outer periphery can sufficiently alert the driver, but the vibration generated by the contact between the wheels and the rollers is transmitted to the sounding body. The vibration may be output, and the vibration may be converted into an electric signal.
Further, the vibration may be detected by a sensor such as a piezoelectric element, a microphone, an electric contact, or a Hall element, and the sensor input may be converted into an electronic sound or a light signal including a human voice.
In addition, it detects a state of staying at the place for a certain period of time or more and issues a warning display, warning sound, and voice warning indicating `` reverse running '' oriented in a direction that only the driver of the reverse traveling mobile can see. May be. At this time, if it is recognized through the video analysis or the sensor that the moving object is within a predetermined range, the moving object may be regarded as staying due to traffic in the forward direction and no warning is issued.

(Fig.12,13 Speed reduction road bump, roller, curve)
One or more deceleration load bumps or one or more deceleration load bumps may be placed on the road surface before the intruding moving object to be blocked or restrained reaches the moving object blocker according to the present invention, which is disposed on the intruding path of the moving object. By arranging the above-mentioned roller group or a combination of both, the arrangement promotes deceleration by the driver of the intruding moving body, and also physically slows down the intruding moving body. Alternatively, the restraining effect can be further enhanced.
Further, the present invention may be arranged at any place on the uphill where the wheels of the moving body can pass, or from 10 m before the start of the curve requiring deceleration to 10 m from the end of the curve. Alternatively, any combination of the deceleration load bump, a roller group other than the moving object restrictor main body or the moving object restrictor main body, and a curve may be used.

(Motorcycle traffic area)
A portion without rollers may be provided in the center of the lane on the road surface (the area where the four-wheeled vehicle will not be stepped on, the center of the mobile traffic zone) or the roadside zone to provide a two-wheeled vehicle traffic area.

In addition, in response to a four-wheel drive vehicle (4WD vehicle), at least the front wheels and the rear wheels are in contact with the ground even if there is not necessarily a roller group in the entire continuous area sufficiently covering the wheelbase (farthest wheelbase) of the vehicle. If there are a plurality of the rollers in each area, as in the case of other FF vehicles, FR vehicles, and MR vehicles, an effect of inhibiting the moving body is exhibited.
In this case, among the plurality of roller groups disposed in the respective regions where the front wheel and the rear wheel are in contact with the ground, the rollers of any one of the plurality of roller groups may not have a difference in height.

(Roller group installation environment)
Water, high-pressure gas, or the like may be discharged into the space on the road surface where the plurality of rollers are disposed to remove dust, sand, soil, snow, ice, and the like accumulated inside.
Further, a belt conveyor or the like may be placed on the bottom of the space to operate periodically to remove dust, sand, soil, snow, ice, and the like accumulated inside.
Freezing may be prevented by arranging a current-carrying electric heater or spraying water at a temperature that does not freeze, inside or around the roller of the moving object block using the roller group.
Further, the space may be opened without providing a bottom surface.
The bottom surface of the space may be an inclined surface or a sufficiently wide space may be provided for the purpose of removing foreign substances or draining water.

(Figs. 9 and 10)
An example of the moving object restrainer according to the present invention for preventing an intruding moving object and further restraining the intruding moving object will be described with reference to FIG.
When the wheel 01 of the moving object to be restrained enters as shown at 9A and falls between the wheel restraint frames 3a and 3b, rollers 100a to 100d around the turning axes 2a and 2b surround the wheel 01 as at 9B. 5a and 5b are simultaneously jumped up by a spring like 011 by a spring, and 3a or 3b is supported by 5a and 5b so that 3a or 3b does not fall down again by the wheel of the moving body which is going to move forward or backward. It has become.
In such a state, the rotation of the wheel 01 does not touch the road surface, and the turning shaft of 2a or 2b is pulled out, the support of 5a or 5b is removed, or the moving body restraint is released by jacking up or the like. You cannot escape from this mechanism unless you lift the moving object and wheels.
Similarly, FIG. 10 corresponds to a wheel of a large vehicle, in which 4a and 4b having a length corresponding to the wheel diameter are added, and 6a and 6b that can withstand a large load are arranged.

(FIG. 14)
Note that the positions of the pivot axes 2, 2a, 2b of the supporting plates / rods shown in FIGS. 7 to 11 are merely examples, and may be arranged outside the roller group as shown in FIG. The shafts arranged outside the roller group are the turning shafts 14a and 14b, and the members 8a and 8b extending therefrom and holding the rollers 100g and 100h are housed in parallel with the road surface. When the user steps on the moving body restrainer, the roller and the holding portion are turned around the turning axis and rise up by the force of a spring or the like, and receive the force of the wheel to escape, and the rollers 100g and 100j are just received. The holding portions 8a and 8b and the irreversibly expanding 9a and 9b limit the degree of reform of the 8a and 8b, thereby receiving a greater force.

7 to 11 and 14 for restraining an intruding moving object are merely examples of the present invention, and the rotational force of the wheel of the invading moving object, the weight of the moving object and the wheels, the weight of the moving object, If the plurality of rollers capable of contacting the wheels by any one of a moving force, a spring, an electric motor, and a hydraulic pressure have a structure capable of changing their mutual height, the intruding moving body can be restrained.

Also, as shown in FIGS. 7, 9, 10, 11, and 14, the wheel restraint frames 3a, 3b and 4a, 4b, 8a and 8b once raised by the intrusion of the wheels are centered on the shafts 2a, 2b, 14a and 14b. In order to be able to get up and maintain the state, the supporting members 5a, 5b, 6a, 6b, 9a, 9b, or the ratchet structure or the freewheel structure added to the shafts 2a, 2b, 14a, 14b, etc. The reverse rotation preventing structure may be used to prevent the device from falling down again.

(Composite roller turning / turntable)
In the restraining use of the intruding moving body, it is desirable that the actual wheel entry direction of the moving body is close to a right angle with respect to the rotation axis of the roller group, but may be an angle other than a right angle depending on the direction of the invading moving body.
In view of this, a turntable that can turn so that the entire member holding the roller group approaches a right angle to the roller group may be used.
Thereby, the wheel can be more securely restrained.

(FIGS. 7 and 8)
A method of making the direction of the rotation axis of a plurality of roller groups for wheel restraint disposed on a turntable having a rotation axis as shown in FIG. 7 and FIG. 8 perpendicular to the approach direction of the wheel of the intruding moving body will be described. I do.
For example, as shown in FIG. 8A, when the wheel of the intruding moving body enters the wheel restraining turntable obliquely with respect to the rotation axis of the roller group, the plurality of rollers in contact with the wheel become In this way, the turntable may be rotated so that the axis of rotation of the roller on the turntable is perpendicular to the direction of travel, or may enter the axis of rotation of the roller on the turntable, depending on the weight of the wheel and the moving body that have entered. The turntable is automatically corrected and turned around the turning axis 0a so that the rotation axes of the wheels of the moving body are parallel.

The mechanism of the correction turning, the wheel is not perpendicular to the axial direction of the plurality of rollers, but when entering obliquely, when the weight of the moving body and the wheel is added to the roller, the wheel is inclined with respect to the wheel. The roller on the contact surface is subjected to a twisting force, but the plurality of rollers arranged in the rotation axis direction rotate in different rotation directions and different rotation speeds, and the twist is eliminated by turning the turntable. The direction of the plurality of rollers arranged on the turntable is automatically corrected.

(Fig. 11 Deflection of the center of gravity of the turntable)
However, at the time of waiting for the invading mobile unit on the turntable, at least the approach direction of the wheel of the invading mobile unit and the rotation axis of the roller group arranged on the turntable must have a positional relationship close to a right angle. For example, automatic rotation correction by the turntable cannot be expected.

Therefore, among the plurality of rollers arranged on the turntable, the first roller to be stepped on by the wheel, in order to naturally turn in the assumed direction in which the vehicle enters, besides a method using a spring, for example, As in the example shown in FIG. 11, the center of the rotation axis of the turntable is not the center of gravity of the turntable, but the center of the roller 100d that the wheel first steps is eccentric to a position where it becomes heavier in balance,
A rotating shaft 0b is provided by, for example, weighting members near 100d (shaded portions of 11B and 11C), and the entire turntable including the turning shaft of the turntable is vertically moved in a direction in which the intruding vehicle enters. Tilt at least 0.1 degree like θb to the direction,
11C, the meridional section of the turntable having the turning axis in the vertical direction is inclined in the direction in which the intruding vehicle enters, and the turntable is perpendicular to the inclined turntable such as 0c (PL). By re-setting the turntable axis on the plumb line)
The turntable turns and stands still at a position where the center of gravity of the turntable is biased toward 100d and faces the direction in which the invading vehicle enters.

In this way, the rollers can be directed in a specific direction using gravity, and the direction of the intruding wheel does not prevent the turntable from automatically correcting rotation to match the direction of the wheel. Furthermore, by using the turntable, even if the driver of the moving body restrained by the rollers arranged on the turntable tries to steer the wheel by operating the steering wheel to escape from the moving body restraint, the wheel is restrained. Escape is difficult because the turntable you follow moves accordingly.

The turntable does not necessarily need to have a bearing on the rotating shaft, and may be a thrust bearing (bearing that receives a force acting in the axial direction of the rotating body) at a position away from the rotating shaft in the shape of an arc rail. Since it is not necessary to have a turning angle of 90 ° or more, the thrust bearing does not necessarily have to be a closed circle, and may have an arc shape having a part of a circle around the turning axis.

As described above, in the constraining application of the invasive moving body, two or more rollers including the specific two rollers are provided with an axis passing through a plane formed by the rotation axis of some specific two rollers among the plurality of rollers. It is possible to use a turntable that has a rotating shaft that holds a frame that rotatably arranges, and that the center of gravity is biased in the assumed invasion direction of the intruding moving body, not necessarily a turntable in which the entire roller group can rotate with one rotating shaft May be.

(Material of turntable)
If the weight of the members constituting the turntable for the purpose of restraining the intruding moving body is heavy, the follow-up speed at which the rotation angle of the turntable and the wheels match due to its inertia becomes slow. However, it should be made of a lightweight composite material such as FRP or CFRP, or a light metal such as an aluminum alloy, as opposed to the purpose of preventing reverse running described in this application. There is no need to worry about the wear of the rollers and the like due to the passage of air, and it should be selected based on pure strength against load and impact and its lightness.
