Description

  The present invention relates to a traffic direction regulating device that prevents reverse running such that, for example, a road with a predetermined traffic direction such as an entry / exit road of an automobile road is erroneously passed in the reverse direction.

  In recent times when traffic conditions have become complicated, there are many roads with a fixed direction of traffic, such as roads for exclusive use of automobiles and service areas, and the structure of these roads is also becoming more complex.

In such a situation, for example, if a vehicle runs backward on an exit road, there is a possibility of a frontal collision between a vehicle that correctly passes the exit road and exits and a vehicle that runs backward by mistake.
Therefore, it is important to check a vehicle that passes in the wrong direction, shut it off, and stop it. For example, the reverse running vehicle stop device disclosed in Patent Document 1 is one of them.

  The reverse running vehicle stop device is provided on the exit side of the one-way street, and includes a detecting means for detecting the reverse running vehicle and a stopping means capable of stopping the reverse running vehicle. When reverse running of the vehicle is detected, the stop means is operated to stop the reverse running vehicle.

The reverse running vehicle stop device configured as described above detects the reverse running vehicle using a sensor and controls the stopping means based on the detection result, and can detect and stop the reverse running vehicle with high accuracy. It is supposed to be possible.
However, the reverse running vehicle stop device requires a large amount of installation work and running costs for the installation of sensors and control devices that accurately detect reverse running vehicles and the operation using electricity. It was difficult to do.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a traffic direction regulating device that can safely block a reverse movement of a moving body and can pass safely with a simple structure.

The present invention is installed on a passage where the direction of travel is set in one direction, and projects on the road surface in a reverse direction of a moving body that moves by rolling means that rolls on the road surface. The blocking means for blocking rolling of the rolling means, and the moving body in the forward direction from the blocking state for blocking the passage of the moving body in the reverse direction by protruding from the road surface by passing the moving body in the forward direction. The blocking means that has shifted to a passage-permitted state that allows passage is constituted by return means that returns to the blocked state after passing in the forward direction of the moving body, and is arranged with two intervals arranged at predetermined intervals in the passage direction An elevating unit and a balance mechanism that supports the elevating unit from below in the form of an upper pan, and the elevating unit is inclined on the front side in the forward direction, which is the side facing the moving body that passes in the forward direction. And the blocking means is the road The lifting and lowering portion is in the protruding position that is in a blocking state that protrudes from above and blocks the passage of the moving body in the reverse direction, and the return means is configured such that one of the two lifting and lowering portions is the road surface. In the state where it protrudes from above and is in a protruding position that is a blocking state that blocks the passage of the moving body in the reverse direction, the other lifting portion is in a low position that is a passage-permitted state that allows passage of the moving body, and is in the forward direction The rolling means of the moving body that moves to the low position is moved along with the movement from the protruding position to the low position by rolling on the lifting part at the protruding position through the inclined side surface. It is a traffic direction control apparatus comprised by the said balance mechanism supported in the aspect which the other raising / lowering part moves to a protrusion position, It is characterized by the above-mentioned.

The above-mentioned traffic road can be an automobile exclusive road, a bicycle exclusive road, a general road, a railway, a track, a monorail, or the like.
The rolling means may be a tire, a wheel, or the like, and the moving body is a moving body that is moved by a rolling means such as an automobile such as a passenger car or a truck, a motorcycle, a bicycle, a train, a monorail, or a battery. be able to.
The return means may be a means for returning by a leaf spring, a coil spring, compressed air, an electromagnet or the like.

  According to the present invention, the moving body is installed in a traffic path having a one-way direction, and the moving body that travels in the reverse direction protrudes from the road surface and is blocked. It is possible to allow passage of the moving body in the positive direction by shifting from the blocked state to the passage-permitted state.

Therefore, a simple structure, it is possible to realize a safe passage to surely block the reverse passage of the moving body.

Specifically, it is possible to reliably block the backward passage of the moving body with the lifting part located at the protruding position protruding from the road surface among the two lifting parts arranged at a predetermined interval in the passage direction.

  In addition, when the two lifting parts arranged at a predetermined interval in the passage direction are in a protruding position where one of them is blocked by the balance mechanism, the other lifting part allows passage of the moving body. The rolling means of the moving body that moves in the forward direction is a low position, and the rolling means moves from the protruding position to the low position by rolling on the elevating part at the protruding position via the inclined side surface. As the other lift part at the low position moves to the protruding position as it moves, the two lifting parts move between the protruding position and the low position by moving the moving body in the forward direction. The body can be allowed to pass in the positive direction.

  Further, in the state where the return means is in a protruding position in which one of the two lifting parts protrudes from the road surface and blocks the passage of the moving body in the reverse direction, The elevating part is in a low position where the moving body is allowed to pass, and the rolling means of the moving body moving in the forward direction rolls on the elevating part at the protruding position via the inclined side surface. Since the balance mechanism is configured to support the other lifting unit in the low position as it moves from the projecting position to the low position by moving the projecting position to the projecting position, another driving force is required. Instead, it is possible to effectively use the energy of the moving body in the forward direction that is moved from the protruding position of one lifting section to the low position, and to return the other lifting section from the low position to the protruding position. Therefore, with a simple structure that does not require a separate power source, it is possible to reliably block the reverse passage of the moving body and realize safe passage.

Can be provided.

  The reverse direction passage detection mechanism is a mechanism for detecting rolling on the back side lifting unit by the rolling means of the moving body that passes in the reverse direction, and by the rolling of the rolling means of the moving body that passes in the reverse direction. It can be a mechanism that detects by moving in the reverse direction, moving in the positive direction by the rolling reaction force, sinking by rotating on the back side lifting unit at the low position, rotating, and the like.

  The blocking effect increasing means is, for example, means for increasing the size of the front-side blocking lifting / lowering section, means for projecting another member from the front-side blocking lifting / lowering section, or LED, It can be set as an electro-optical display means.

  According to the present invention, it is possible to block the passage of the moving body in the reverse direction by the front side blocking lift at the protruding position. In addition, the reverse passage detection means detects the reverse passage by the moving body and increases the blocking effect on the moving body of the reverse passage by the front side blocking elevating part. Can be blocked.

  Further, as an aspect of the present invention, the balance mechanism includes a connection arm that connects the lifting unit and supports the lower part, and a balance fulcrum that pivotally supports the connection arm, and is in front of the balance fulcrum. A near-side moment to the side blocking lift can be set to be smaller than a back-side moment from the balance fulcrum to the back-side lift.

  The front moment from the balance fulcrum to the front side blocking lift is set to be smaller than the back moment from the balance fulcrum to the back lift. If the weight of the front side blocking lift is configured to be lighter than the weight of the back lifting unit, or the front side blocking lifting unit and the back lifting unit are configured with the same weight, the connecting arm The arm length on the near side from the balance fulcrum is configured to be shorter than the arm length on the back side, or the arm weight of the front arm on the connecting arm is configured to be lighter than the arm weight of the back arm. Including setting the moment to be smaller than the back moment.

  As a result, the near-side blocking lifting and lowering unit supported by the balance mechanism in the form of an upper pan balance from below can be configured such that the near-side blocking lifting and lowering unit is in the protruding position in the normal state. .

  Specifically, by setting the near side moment from the balance fulcrum to the near side cutoff lifting part to be smaller than the back side moment from the balance fulcrum to the far side lifting part, the balance mechanism makes an upper scale-like shape. In the no-load state, the front side lifting and lowering part supported from below is the low position of the large rear side lifting part and the front side blocking lifting part having the small moment is the protruding position. Balance.

  Therefore, in the no-load state where the rolling means does not roll on the lifting part, that is, in the normal state, the front-side blocking lifting part is held at the protruding position and the rear lifting part is held at the low position without providing another mechanism. can do. Therefore, it is possible to reliably block the reverse passage of the moving body.

  In addition, as an aspect of the present invention, the compressed air is stored in the compressed air tank, and has a pressure valve for releasing the compressed air at a predetermined pressure or higher, and the compressed air in the compressed air tank by a balance operation by the balance mechanism. And the blocking effect increasing means is constituted by a protruding amount increasing mechanism for moving the near-side blocking elevating part in a direction to increase the protruding amount by the compressed air stored in the compressed air tank. be able to.

  In the above balance operation, one of the two lifting parts is in the protruding position, the other is in the low position, and the other lifting part is moved from the low position as the one lifting part moves from the protruding position to the low position. It can be set as the operation | movement which moves to a protrusion position.

  According to the present invention, since the front side blocking lift is moved in the direction of increasing the amount of protrusion by the compressed air stored in the compressed air tank, the reverse passage by the moving body can be reliably blocked.

  In addition, since the air pump for supplying the compressed air to the compressed air tank by a balance operation by the balance mechanism is provided, the compressed air is stored in the compressed air tank by passing the moving body in the forward direction, and the compressed air tank In order to move the front side blocking lift by the compressed air stored in the front, the moving energy of the moving body that passes in the forward direction is stored without the need of another drive source, and the front side blocking lift is moved and moved. Reverse passage by the body can be reliably blocked.

  Moreover, since the compressed air tank which stores compressed air inside is provided with a pressure valve for releasing the compressed air above a predetermined pressure, even when the compressed air above the predetermined pressure is supplied by an air pump Compressed air can be stored safely.

  Further, the present invention allows a traveling vehicle that is installed on a one-way road whose traveling direction is set to one direction and moves by a tire that rolls on the road surface to travel in the forward direction, and is reverse to the traveling vehicle. Is a traffic direction regulating device that regulates the traveling of the vehicle, and is disposed at a predetermined interval in the traveling direction, is located on the near side in the traveling vehicle that travels in the forward direction, and the near side blocking elevation that is an inclined surface on the near side , A back side elevating part serving as a back side, a balance mechanism for supporting both the elevating parts in the form of an upper pan from below, and a compressed air tank that stores the compressed air and releases a pressure of a predetermined value or more And an air pump that supplies the compressed air to the compressed air tank by a balance operation by the balance mechanism, and a bulging body that is normally folded and stored and bulges by the supply of compressed air to the inside. Structure The lifting mechanism is composed of a connecting arm for connecting and lowering the lifting unit and a balance fulcrum for pivotally supporting the connecting arm. In the projecting position that is a blocking state that blocks the vehicle in the reverse direction by protruding from the road surface, the other elevating part is in a low position that is a traffic permitting state that allows the vehicle to pass, and is in the positive direction As the tire of the vehicle that moves to the vehicle rolls on the lifting part at the protruding position via the inclined side surface, the other lifting / lowering at the low position is caused by the movement from the protruding position to the low position. The front side moment from the balance fulcrum to the near side cutoff lift is the back side moment from the balance fulcrum to the back side lift. The slide mechanism configured to be slidable in the travel direction with respect to the balance mechanism, and the reverse travel on the back side lift at the low position. A reverse travel detection mechanism that detects reverse travel by sliding of the back side lifting unit by the slide mechanism as the tire of the travel vehicle travels, and the reverse travel detection means detects the reverse travel of the travel vehicle. By the detection, the compressed air is supplied from the compressed air tank to the bulging body to bulge the bulging body.

  The traveling vehicle may be a car such as a passenger car or a truck, a motorcycle, or a bicycle.

  The reverse-direction detection mechanism is a mechanism that detects the rolling of the tire of a traveling vehicle that travels in the reverse direction. The sliding mechanism moves and rolls in the reverse direction due to the rolling of the tire of the traveling vehicle that travels in the reverse direction. It can be a mechanism that detects by moving the slide mechanism in the positive direction due to the reaction force.

  The distance from the balance fulcrum to the lifting part, that is, the connecting arm, is set so that the near side moment from the balance fulcrum to the near side cutoff lifting part is smaller than the back side moment from the balance fulcrum to the back lifting part. The same configuration on the back side and the front side, when the weight of the front side blocking lifting part is configured to be lighter than the weight of the back side lifting part, or the front side blocking lifting part and the back side lifting part are configured with the same weight, Configure the arm length on the near side from the balance fulcrum in the connection arm shorter than the arm length on the back side, configure the arm weight of the front arm on the connection arm to be lighter than the arm weight of the back arm, or combine them, Including setting the near side moment to be smaller than the back side moment.

  In the above balance operation, one of the two lifting parts is in the protruding position, the other is in the low position, and the other lifting part is moved from the low position as the one lifting part moves from the protruding position to the low position. It can be set as the operation | movement which moves to a protrusion position.

  According to the present invention, the two lifting parts installed on the one-way road with the one-way direction set at a predetermined interval and arranged at a predetermined interval in the one-way direction are protruded from the road surface by the balance mechanism and are reversely directed. It is composed of an elevating part at a protruding position that is a blocking state that blocks the passage of the traveling vehicle, reliably blocks reverse traveling of the traveling vehicle, and moves the elevating part from the blocked state by passing in the forward direction of the traveling vehicle. It is possible to allow passage of the traveling vehicle in the positive direction by shifting to the passage permission state.

  Therefore, with a simple structure, the reverse passage of the traveling vehicle can be reliably blocked and safe passage can be realized.

  Further, when the two lifting parts arranged at a predetermined interval in the passage direction are in the protruding position where one of them is blocked by the balance mechanism, the other lifting part allows the passage of the traveling vehicle. Is the low position. And, as the tire of the traveling vehicle moving in the forward direction rolls on the elevating part at the protruding position through the inclined side surface, the low position is moved along with the movement from the protruding position to the low position. The other lifting / lowering part is supported in such a manner that it moves to the protruding position. Accordingly, the two elevating parts can switch the protruding position and the low position by allowing the traveling vehicle to pass in the forward direction, and allow the traveling vehicle to pass in the forward direction.

  In addition, the balance mechanism is configured to move up and down from the protruding position to the low position by rolling the tire of the traveling vehicle moving in the forward direction on the lifting section at the protruding position via the inclined side surface. As the other lifting / lowering part in the low position is supported in a manner to move to the protruding position with the movement of the other, no separate driving force is required, and the movement of one lifting / lowering part from the protruding position to the low position is performed. The energy of the traveling vehicle traveling in the forward direction can be effectively used, and the other lifting / lowering unit can be returned from the low position to the protruding position. Therefore, with a simple structure that does not require a separate power source, the reverse passage of the traveling vehicle can be reliably blocked and safe passage can be realized.

  In addition, by setting the near side moment from the balance fulcrum to the near side cutoff lifting part to be smaller than the back side moment from the balance fulcrum to the back side lifting part, the balance mechanism makes an upper pan like a balance. The near-side lifting / lowering part supported from below is balanced with the rear-side lifting / lowering part with a large moment at the low position and the front-side breaking / lifting part with a small moment at the protruding position in the no-load state. . Therefore, in a no-load state where the tire does not roll on the lifting part, that is, in a normal state, the front side blocking lifting part is held at the protruding position and the rear lifting part is held at a low position without providing another mechanism. Can do. Therefore, the reverse passage of the traveling vehicle can be reliably blocked.

  In addition, the reverse passage detection means detects reverse passage by the traveling vehicle and supplies the compressed air from the compressed air tank to the bulging body to bulge the bulging body. In addition, it is possible to reliably block the reverse travel of the traveling vehicle.

  In addition, since it includes an air pump that supplies the compressed air to the compressed air tank by a balance operation by the balance mechanism, the compressed air is stored in the compressed air tank by passing in the forward direction of the traveling vehicle. In order to move the front side blocking lift by the compressed air stored in the vehicle, the traveling energy of the traveling vehicle that passes in the forward direction is stored without a separate drive source, and the front side blocking lift is moved to travel. Reverse traffic by the vehicle can be reliably blocked.

  Moreover, since the compressed air tank which stores compressed air inside is provided with a pressure valve for releasing the compressed air above a predetermined pressure, even when the compressed air above the predetermined pressure is supplied by an air pump Compressed air can be stored safely.

  According to the present invention, it is possible to provide a traffic direction restricting device that can safely pass with a simple structure and reliably block the backward traffic of a moving body.

  An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram of the elevating traveling direction regulating device 1 shown in a perspective view, and FIG. 2 is an explanatory diagram of the elevating traveling direction regulating device 1 shown in a side sectional view.
1A shows a perspective view of the elevating traveling direction regulating device 1 at the protruding position U that blocks the traveling of the reverse traveling vehicle traveling in the direction of arrow B, and FIG. The perspective view of the raising / lowering type traveling direction control apparatus 1 in the lowest position D which accept | permits driving | running | working of the positive direction driving | running | working motor vehicle which drive | works in a positive direction is shown.

  2A is a side sectional view of the elevating traveling direction regulating device 1 at the protruding position U that blocks the traveling of the vehicle in the direction of arrow B, and FIG. 2B is the traveling of the forward traveling vehicle. The side sectional drawing of the raising / lowering type traveling direction control apparatus 1 in the lowest position D which accept | permits is shown.

  The elevating traveling direction regulating device 1 is formed in a triangular column shape in a sleeping position that is long in the orthogonal direction and protrudes upward from the road surface 100a with respect to the one-way street 100 in which the direction of travel is determined with the arrow A direction as the forward direction. ing.

  Specifically, the one-way street 100 is an automobile road or service area exit, and a car exiting the one-way street 100 travels in the forward direction indicated by arrow A and travels in the reverse direction indicated by arrow B. It is a one-way road that regulates the traffic of reverse-running cars. It may be a one-way road such as an entrance.

  Further, as shown in FIG. 2, the elevating traveling direction regulating device 1 is elevating together with an elevating block 10 having a substantially right triangle shape in side view, a coil spring 17 that urges the elevating block 10 upward, and a coil spring 17. It is comprised with the accommodation space 20 which accommodates the raising / lowering block 10 as possible.

The accommodation space 20 has a projecting opening 21 that penetrates to the road surface 100a in the upper part and allows the lifting block 10 to project upward, and a spring opening 22a that allows the coil spring 17 to penetrate. It is an internal space of the one-way road 100 that is configured by a partition board 22 that partitions in a direction.
In addition, the protrusion opening 21 forms the to-be-latched part 21a which accept | permits the latching | locking rod 13 of the raising / lowering block 10 mentioned later in a peripheral part.

  The partition plate 22 is formed at a height position where the lift block 10 is placed on the upper surface of the partition plate 22 in a state where the later-described lift block 10 is at the lowest position D, and at the lowest position D. The top part 16 of a certain raising / lowering block 10 is formed so that it may become substantially the same height as the road surface 100a.

The elevating block 10 is formed in a triangular prism shape in a sleeping position having a width direction length that is slightly wider than a vehicle width of a normal automobile (not shown).
The lifting block 10 is placed on the upstream side in the positive direction indicated by the arrow A direction (the back right side in FIG. 1 and the right side in FIG. 2), and on the inclined surface 11, the downstream side (the left front side in FIG. 1 and the left side in FIG. 2). ) Is a right-angled triangle in a side sectional view having a vertical surface 12. And the locking rod 13 which protrudes in the front-back direction in the arrow A direction at the lower end of the boarding inclined surface 11 and the vertical surface 12 is provided.

Further, a bottom surface 14 having a substantially right triangle shape in a side sectional view is provided with a spring fitting hole 15 that allows the coil spring 17 to be fitted.
The upper end of the coil spring 17 is fitted in the spring fitting hole 15 of the elevating block 10 and is placed on the bottom surface 23 of the accommodating space 20. Although not shown, the urging force that urges the elevating block 10 upward is omitted. In order to ensure this, a plurality of lifting blocks 10 are arranged at predetermined intervals in the width direction W (FIG. 1).

  The lifting block 10 having the above-described configuration is placed on the bottom surface 23 and is housed in the housing space 20 with the upper end of the coil spring 17 penetrating the spring opening 22a fitted in the spring fitting hole 15 so as to move up and down. The restriction device 1 is configured. At this time, in a normal state F in which no load from above is applied to the lifting block 10, the lifting block 10 penetrating the protruding opening 21 is in the road surface 100a in a state where the locking rod 13 is locked to the protruding opening 21. It becomes the protrusion position U which protrudes from.

In the elevating block 10 at the protruding position U, the upstream side forms a slope that continues from the road surface 100a by the entering slope surface 11, and the downstream side is in a state in which the vertical surface 12 stands vertically from the road surface 100a. Incidentally, the top of the up to 16 height of the lifting block 10 from the road surface 100a in the protruding position U, that is, the height of the vertical surface 12, that are formed at approximately the same height as the radius of the tire 200 illustrated omitted vehicles ( FIG. 2 (a)) .
Further, as shown in FIG. 1 (a), the vertical surface 12 that stands up from the road surface 100 a has the characters “reverse” or “×” that can be seen by the driver of the vehicle in the reverse direction indicated by the arrow B. "Is displayed.

In the elevating traveling direction regulating device 1 having such a configuration, as shown in FIG. 2A, the tire 200 of the forward traveling vehicle in the direction of arrow A enters the inclined surface 11 as it is from the road surface 100 a at the protruding position U. Roll over.

  The lifting block 10 on which the tire 200 rolls on the loading inclined surface 11 moves downward against the urging force of the coil spring 17 and descends to the lowest position D. Since the top portion 16 has been lowered to the lowest position D where the road surface 100a is almost the same height as the road surface 100a, the tire 200 of the automobile traveling in the direction of arrow A can roll and move downstream (FIG. 1 (b). ) And FIG. 2 (b)).

  On the other hand, the reverse running tire 200a of the reverse running vehicle that runs in the reverse direction (arrow B direction) from the downstream side to the upstream side in the forward direction indicated by the arrow A is in a state of standing vertically from the road surface 100a. The height from the road surface 100 a to the top portion 16 abuts on the vertical surface 12 set to the same height as the radius of the tire 200. However, the reverse running tire 200a running in the direction of the arrow B cannot get over the lifting block 10 and roll upstream, and the lifting tire 10a at the protruding position U rolls the running tire 200a from the arrow B direction. Is cut off.

  In addition, since a warning display 18 of “reverse” and “x” is displayed above the road surface 100a of the vertical surface 12 at the protruding position U, the driver of the reverse running vehicle uses the lifting block 10 to move the reverse running tire 200a. Even if the rolling is not interrupted, it is possible to recognize the display of the warning display 18 and recognize the traveling in the arrow B direction.

  In this way, the one-way road 100 is provided with the lifting block 10 that protrudes upward from the road surface 100a at the protruding position U, so that the reverse running tire 200a of the reverse running vehicle rolls against the vertical surface 12 of the lifting block 10. Therefore, it is possible to increase the safety of traffic on the one-way road 100 in which the direction of traffic with the arrow A direction as the positive direction is set.

  In addition, although the one-way street 100 is configured in a continuous shape that is slightly longer than the vehicle width of a general automobile, the left and right tires 200 based on the vehicle width of the one-way street 100 are independent of each other. The elevating traveling direction regulating device 1 may be formed.

A posture regulating unit 42 for regulating the posture is provided.
In addition, as shown in FIG. 4A, the blocking plate 40 in the standing posture S is formed so as to have almost the same height as the radius of the automobile tire 200 (not shown).

  In addition, the inclined curved surface 41 displays an upward arrow display 41a in the standing posture S, and the downstream side surface 40a of the blocking plate 40 in the standing posture S is directed to the vehicle driver in the reverse direction indicated by the arrow B. A “reverse” character that can be visually confirmed and a warning display 40b of “×” are displayed.

  The torsion spring 35 is a torsion spring fitted to the outer periphery of the hinge 31 and is formed in a reverse letter shape as shown in FIG. It is energizing in the opening direction.

  As shown in FIG. 1 of FIG. 4, the tilting travel direction regulating device 1 a configured as described above is configured so that, in the normal state F, the blocking plate 40 is a reverse running tire indicated by an arrow B by the urging force of the torsion spring 35. The standing posture S, which is a blocking state that blocks the rolling of 200a, is held. At this time, as shown in the enlarged view of part a in FIG. 4B, the restricting convex portion 34 abuts on the posture restricting portion 42 of the blocking plate 40 to restrict the tilting of the blocking plate 40 toward the upstream side. ing.

  In this state, when the tire 200 rides up from the inclined curved surface 32 and hits the blocking plate 40 in the standing posture S from the upstream side, the blocking plate 40 tilts in the positive direction indicated by the arrow A against the urging force of the torsion spring 35. (Fig. 2).

  Further, as the rolling of the tire 200 progresses, the blocking plate 40 tilts to the tilting posture X, and enters a passage permission state that allows rolling downstream (FIG. 3). In this state, the torsion spring 35 is urged inward as shown in the enlarged view of portion b in FIG. 4C, so that when the tire 200 passes over the blocking plate 40, the torsion spring 35 Due to the urging force, the blocking plate 40 in the tilted posture X returns to the standing posture S (FIG. 4).

  On the other hand, the reverse running tire 200a of the reverse running vehicle that runs in the reverse direction (arrow B direction) from the downstream side to the upstream side in the forward direction indicated by the arrow A is set to a height that is substantially the same as the radius, and is standing. It cannot roll over the blocking plate 40 in the posture S to the upstream side. Therefore, the rolling of the reverse running tire 200a from the direction of the arrow B can be blocked by the blocking plate 40 in the standing posture S.

  Further, since the warning display 40b is displayed on the downstream side surface 40a of the blocking plate 40 in the standing posture S, the warning display 40b of “reverse” and “×” is displayed, so that the driver of the reverse running vehicle can run backward with the blocking plate 40. Even if the rolling of the tire 200a is not interrupted, it is possible to recognize the display of the warning display 40b and recognize the traveling in the arrow B direction.

  In this way, the one-way road 100 is provided with the tilting traveling direction regulating device 1a having the blocking plate 40 protruding upward from the road surface 100a in the standing posture S, so that the reverse traveling tire 200a of the reverse traveling vehicle is provided. Since the rolling is blocked by the blocking plate 40 in the standing posture S, it is possible to increase the safety of traffic on the one-way road 100 in which the direction of traffic with the arrow A direction as the positive direction is set.

  In addition, since the tilting travel direction regulating device 1a mounts and fixes the base plate 30 on the one-way street 100, it can be easily installed without requiring a large installation work or the like, and convenience is improved. .

  Furthermore, as a return means for returning the blocking plate 40 tilted to the tilted posture X to the standing posture S, the biasing force of the torsion spring 35 when the blocking plate 40 is tilted by rolling of the tire 200 of the forward traveling vehicle is used. Therefore, the traveling energy of the forward traveling vehicle can be effectively utilized and returned. Therefore, with a simple structure that does not require a separate power source, it is possible to reliably block reverse traffic of the reverse running vehicle and realize safe traffic.

  Although the tilting traveling direction regulating device 1a for mounting and fixing the base plate 30 on the one-way street 100 has been described, as shown in FIG. 5, the tilting traveling direction of the type configured to be embedded in the one-way street 100. Even with the regulating device 1a ′, the same effect can be obtained.

  In addition, the one-way road 100 is configured to have a continuous shape that is slightly longer than the vehicle width of a general automobile. However, the one-way road 100 is independent in the portion through which the left and right tires 200 pass based on the vehicle width of the one-way road 100. The tilting traveling direction regulating device 1a may be formed.

A reverse running tire 200a that rolls in the direction of arrow B is detected, and an expanded state Z in which the air balloon 71 is expanded is shown.

  The balance-type traveling direction regulating device 1b includes two blocking blocks 60 arranged at a predetermined interval in the direction of arrow A, a balance mechanism 50 that supports the blocking blocks 60 in the form of an upper balance, and an air balloon mechanism 70. And an internal space 80 in which the balance mechanism 50 and the air balloon mechanism 70 are accommodated.

  The blocking block 60 is placed on the upstream side (right rear side in FIGS. 6 and 7 and on the right side in FIG. 8) in the positive direction indicated by the arrow A direction, and on the inclined side 61 on the downstream side (left front side in FIG. 1 and left side in FIG. 2). ) In the side view half tilted trapezoid formed by the vertical surface 62, the boarding inclined surface 61 and the horizontal upper surface 63 disposed at the upper end of the vertical surface 62. And the locking rod 64 which protrudes in the front-back direction in the arrow A direction is provided in the lower end of the boarding inclined surface 61 and the vertical surface 62. As shown in FIG.

  Of the two blocking blocks 60 arranged at a predetermined interval in the direction of arrow A, the upstream upstream side in the direction of arrow A is an upstream blocking block 60b, and the downstream side is a downstream blocking block 60a.

  Further, as shown in the enlarged view of FIG. 8 (b), a pump cylinder 72a protrudes downward from the bottom surface inside the upstream blocking block 60b, and an air pump 72 that supplies compressed air and a supply from the air pump 72. An air tank 73 for storing the compressed air, an air balloon 71 bulging by the compressed air discharged from the air tank 73, and a discharge switch 74 for releasing the compressed air from the air tank 73 to the air balloon 71. .

  The air balloon 71 is folded and accommodated inside the upstream blocking block 60b, and a swivel lid that is pivoted by a hinge 75a disposed on the upper side is placed on the inclined slope 61 on the upper side of the folded air balloon 71. 75 is formed.

  In addition, since the air tank 73 includes a pressure valve 73a that releases the compressed air at a predetermined pressure or higher, even if the compressed air is excessively supplied from the air pump 72, the air tank 73 is compressed with a storage amount exceeding the predetermined pressure. Compressed air can be stored safely without storing air.

The balance mechanism 50 includes a support arm 54 that supports the blocking block 60, a connection arm 52 that includes a swing arm 53 that is pivotally connected to both ends of the support arm 54, and a connection arm 52 that supports the connection arm 52 in a swingable manner. The balance fulcrum shaft 51 is configured.
Three sets of connecting arms 52 are arranged at a predetermined interval in the width direction W, and the balance fulcrum shaft 51 is arranged to connect the three sets of connecting arms 52 in the width direction W.

  The support arm 54 is pivotally supported by a pivot shaft 55 (FIG. 7 (a)) disposed inside the blocking block 60. As shown in the enlarged view of part a in FIG. 8 (b), the support arm 54 is pivotally supported. An arc locking groove 65 convex in a side view is formed in the upstream blocking block 60b so that the shaft 55 can move in the front-rear direction in the direction of arrow A (left-right direction in FIG. 8).

  Similarly, as shown in the enlarged view of the portion b in FIG. 8C, the arc-shaped latch that is convex in a side view so that the pivot shaft 55 can move in the front-rear direction in the arrow A direction (left-right direction in FIG. 8). A groove 65 is formed inside the downstream blocking block 60a.

  In the swing arm 53, the length from the balance fulcrum shaft 51 to the back support arm 54a that supports the downstream blocking block 60a is the back arm length L1, and the upstream blocking block 60b is supported from the balance fulcrum shaft 51. The length to the near side support arm 54b to be performed is the near side arm length L2.

  Further, of the moment M acting on the balance fulcrum shaft 51, the downstream blocking block 60a side is the downstream moment M1, and the upstream blocking block 60b side is the upstream moment M2. In this embodiment, the upstream moment M2 that is upstream in the positive direction of the arrow A is configured to be smaller than the downstream moment M1 on the downstream side.

  Specifically, since the moment M is determined by a multiplier of the arm length L from the balance fulcrum shaft 51 to the blocking block 60 and the weight from the balance fulcrum shaft 51 to the blocking block 60, the near side arm length L2 is set to the back side arm length. The upstream moment M2 is made smaller than the downstream moment M1 by forming it shorter than L1 or by forming the weight from the balance fulcrum shaft 51 to the upstream blocking block 60b to be lighter than the weight from the balance fulcrum shaft 51 to the downstream blocking block 60a. It is configured to be smaller.

  As shown in FIG. 8, the internal space 80 for accommodating the balance mechanism 50 and the blocking block 60 includes a downstream block receiving section 80a for storing the downstream blocking block 60a, a balance receiving section 80c for storing the balance mechanism 50, This is an internal space formed inside the one-way street 100, which communicates with the upstream block housing section 80 b that houses the upstream blocking block 60 b.

  As shown in the enlarged view of part b in FIG. 8C, the downstream block housing section 80a has a protruding opening 81 that penetrates up to the road surface 100a and allows the downstream blocking block 60a to protrude upward. A slide flange 83 provided near the center in the height direction of the downstream side surface in the side block housing section 80a, and a height restricting portion 84 for restricting the downstream blocking block 60a slid by the slide collar 83 to a position lowered by one step. It consists of and. And it is connected to the balance accommodation section 80c below the slide collar 83 and the height regulation section 84 of the downstream block accommodation section 80a.

  The slide collar 83 includes a first collar 83a with which the bottom surface of the downstream blocking block 60a at the lowest position D abuts, and a bottom surface of the downstream blocking block 60a whose height is regulated by the height regulating unit 84. Is formed in a stepped shape with the second flange 83b with which it comes into contact.

  Further, the height restricting portion 84 is configured to protrude inward in the width direction W on the side surfaces on both sides in the width direction of the downstream block accommodation section 80a so as not to hinder the swing of the swing arm 53. Further, the protruding opening 81 forms a locked portion 82 that allows the locking rod 64 of the downstream blocking block 60a to be locked at the peripheral edge.

  Due to the configuration of the downstream block housing section 80a, the downstream blocking block 60a can be moved up and down in the up-down direction above the first flange 83a, and from the lowest position D where the bottom surface abuts on the first flange 83a. While sliding to the upstream side (right side in FIG. 8), it is possible to move to another position where the bottom surface is in contact with the upper surface of the height regulating portion 84 (reverse running detection position G). The slide hook 83 and the circular arc engaging groove 65 constitute a slide mechanism in which the downstream blocking block 60a can slide in the front-rear direction of the arrow A direction.

  As shown in the enlarged view of a part in FIG. 8 (b) and the enlarged view of part c in FIG. 8 (d), the upstream block accommodation section 80b penetrates to the road surface 100a in the upper part and is located above the upstream blocking block 60b. A protrusion opening 81 that allows protrusion to the upper surface, a pressing surface 85 provided near the center in the height direction of the upstream block housing section 80 b, and a bottom surface of the upstream blocking block 60 b at the lowest position D where the bottom surface is located on the pressing surface 85. Is connected to the balance accommodation section 80c below the height regulation section 84 of the upstream block accommodation section 80b.

  The height restricting portion 84 is configured to protrude inward in the width direction W on the side surfaces on both sides in the width direction of the upstream block accommodation section 80b so as not to hinder the swing of the swing arm 53. Further, the protruding opening 81 forms a locked portion 82 that allows the locking rod 64 of the upstream blocking block 60b to be locked at the peripheral edge.

  The operation of the balance type travel direction regulating device 1b configured as described above will be described. First, in the normal state F, since the upstream moment M2 is set to be smaller than the downstream moment M1, the upstream blocking block 60b protrudes above the road surface 100a from the protruding opening 81 of the upstream block accommodating section 80b. The downstream blocking block 60a connected to the upstream blocking block 60b via the balance mechanism 50 becomes the lowest position D accommodated in the downstream block accommodating section 80a (FIG. 7A). ) And FIG. 8 (a)). At this time, the upper horizontal upper surface 63 of the downstream blocking block 60a slightly protrudes from the road surface 100a.

  In this state, the tire 200 of the forward traveling vehicle rolls from the upstream side of the balance-type traveling direction regulating device 1b and rides on the sloping surface 61 of the upstream blocking block 60b at the protruding position U and travels downstream. As a result, the upstream blocking block 60b is lowered to the lowest position D due to the weight of the vehicle and enters the upstream passage allowable state Ya. Then, the downstream blocking block 60a connected via the balance mechanism 50 rises to the protruding position U (see FIGS. 7B and 8B).

  At this time, the air pump 72 b that protrudes downward from the bottom surface of the upstream blocking block 60 b is compressed by the pressing surface 85, and the air pump 72 is activated to supply compressed air to the air tank 73.

  Further, rolling of the tire 200 in the positive direction in the direction of arrow A proceeds, and rides on the loading inclined surface 61 of the downstream blocking block 60a in the protruding position U and proceeds downstream, so that the weight of the vehicle The downstream blocking block 60a descends to the lowest position D and enters the downstream passage allowable state Yb. Then, the upstream blocking block 60b connected via the balance mechanism 50 rises to the protruding position U and returns to the normal state F shown in FIGS. 7 (a) and 8 (a). In this way, the balance-type traveling direction regulating device 1b can permit passage of a forward traveling vehicle.

  On the other hand, when the reverse running tire 200a of the reverse running vehicle rolls from the downstream side, in the normal state F, the downstream blocking block 60a at the lowest position D of the aspect in which the horizontal upper surface 63 slightly protrudes from the road surface 100a is upstream. Press to the side. The downstream blocking block 60a pressed against the upstream side by the reverse running tire 200a is, as shown in the enlarged view of part b of FIG. Move upstream.

  When the reverse running tire 200a in the opposite direction rolls and rides on the horizontal upper surface 63 of the downstream blocking block 60a, the height of the downstream blocking block 60a is regulated by the height regulating portion 84 due to the weight of the automobile. Descends to the reverse running detection position G (FIG. 8D).

  At this time, the upstream blocking block 60b connected by the balance mechanism 50 is restricted in the height direction by the locked portion 82 locked by the locking rod 64, and therefore cannot move further upward. . Therefore, the support arm 54b is lifted from below by the swing arm 53, and the upper end of the support arm 54b moves upstream along the arc locking groove 65, and the support arm 54b tilts upstream (FIG. 8D). C section enlarged view).

  Then, the release switch 74 is pressed and actuated by the tilting of the support arm 54b toward the upstream side, and the compressed air stored in the air tank 73 is released to bulge the air balloon 71.

  At this time, the air balloon 71 accommodated in the folded state inside the upstream blocking block 60b bulges upward due to the inflow of compressed air and penetrates the rotary lid 75 to the outside of the upstream blocking block 60b. Spread upward.

  The reverse running detection mechanism for detecting the reverse running of the reverse running tire 200a of the reverse running vehicle is a slide mechanism of the downstream blocking block 60a formed by the arc locking groove 65 and the slide flange 83, and slides downstream. It is composed of a release switch 74 that abuts on the support arm 54b of the upstream blocking block 60b connected by the balance mechanism 50 as the blocking block 60a moves to the reverse running detection position G and is ON-controlled.

  With the above configuration, the balance mechanism 50 supports the two blocking blocks 60 arranged at predetermined intervals in the direction of arrow A from below in the form of an upper balance, and the tire 200 is placed on the upstream blocking block 60b at the protruding position U. After descending to the lowest position D by riding on the sloped inclined surface 61 and proceeding downstream, the tire 200 further rides on the sloped inclined surface 61 of the downstream blocking block 60a at the projecting position U and travels downstream. By proceeding, the upstream blocking block 60b connected via the balance mechanism 50 rises to the protruding position U and returns to the normal state F, so that no additional driving force is required and the energy of the forward armored vehicle is saved. The normal state F can be restored by making effective use. Therefore, with a simple structure that does not require a separate power source, it is possible to securely block the reverse running vehicle and realize safe traffic.

  Further, by setting the upstream moment M2 to be smaller than the downstream moment M1, in the normal state F, the downstream blocking block 60a having a large moment M becomes the lowest position D, and the upstream blocking block 60b having a small moment M is set. Will become the protruding position U and balance. Therefore, in the normal state F, the upstream blocking block 60b can be held at the protruding position U and the downstream blocking block 60a can be held at the lowest position D without providing another mechanism. Therefore, it is possible to reliably block the passage of the reverse traveling vehicle.

  In addition, the air balloon 71 bulges upward from the upstream blocking block 60b located in front of the traveling direction with respect to the vehicle traveling in the direction opposite to the arrow B direction, so that visibility is high and the vehicle travels in the reverse direction. be able to.

  The compressed air for inflating the air balloon 71 is applied to the pressing surface 85 each time the upstream blocking block 60b moves up and down by the air pump 72 in which the pump cylinder 72a projects downward from the bottom surface of the upstream blocking block 60b. The compressed air can be supplied to the air tank 73 by contacting.

  In this embodiment, the air balloon 71 is inflated with the compressed air supplied by the air pump 72 to block the passage of the reverse vehicle in the direction of arrow B. However, as shown in FIG. 9, the upstream side blocking block 60b. The base-side upstream blocking block 60bb serving as the base and the top-side upstream blocking block 60ba that can bulge upward with respect to the base-side upstream blocking block 60bb, and reverse using a slide mechanism By detecting the reverse running tire 200a of the reverse running car by the running detection mechanism, the top upstream upstream blocking block 60ba may be moved upward by the air jack 76 with the compressed air stored in the air tank 73.

  Further, instead of the air pump 72 or in combination with the air pump 72, electricity is stored by raising and lowering the upstream side blocking block 60b or swinging the balance mechanism 50, and for example, an LED lamp embedded in the vertical surface 62 by the electricity is used. A configuration may be used in which the vehicle is turned on and the reverse vehicle in the direction of arrow B is prompted to run backward.

  Further, in the above embodiment, when the reverse running tire 200a of the reverse running vehicle rolls from the downstream side by the slide mechanism of the downstream blocking block 60a formed by the arc locking groove 65 and the slide flange 83, the road surface 100a The downstream blocking block 60a located at the lowest position D in a state in which the horizontal upper surface 63 slightly protrudes is pressed to the upstream side and lowered to the reverse running detection position G. For example, the slide mechanism is moved downstream from the downstream blocking block 60a. You may comprise so that a slide to the side is possible. In this case, the downstream blocking block 60a can be slid to the downstream side by the rolling reaction force of the reverse running tire 200a. Even with this method, a reverse running vehicle can be detected.

The near side moment from the balance fulcrum to the near side cutoff lifting part is set to be smaller than the back side moment from the balance fulcrum to the back side lifting part,
A slide mechanism configured to be slidable in the traveling direction with respect to the back side lifting unit with respect to the balance mechanism;
A reverse travel detection mechanism that detects reverse travel by sliding of the back lift unit by the slide mechanism when a tire of the traveling vehicle traveling in the reverse direction on the back lift unit at the low position travels. And
A traffic direction regulating device for supplying the compressed air from the compressed air tank to the bulging body to bulge the bulging body by detecting the backward traveling of the traveling vehicle by the reverse direction traveling detecting means.
