Abstract

PROBLEM TO BE SOLVED: To provide a gate opening/closing device for vehicle such that a bar member does not move to a passing place without receiving force which is large to some extent and can be put back to its original position with relatively small force.SOLUTION: A bar member 5 of a gate opening/closing device 1 for vehicle can rotate between a no-passing permission position and a passing permission position. When the bar member 5 comes into contact with a vehicle at the no-passing permission position, a root end part of the bar member 5 comes out of a storage part 7 and rotates to a retreat position. When the bar member 5 is at the no-passing permission position, a lock surface part 10 is locked to a lock stage part 13 with the root end part of the bar member 5 stored in the storage part 7. When the bar member 5 is put back from the retreat position to the passing permission position, a guide surface part 14 moves beyond a slope surface part 11 and the root end part of the bar member 5 can be stored in the storage part 7.

Description

  The present invention relates to a vehicle gate opening / closing device used in an ETC system or the like.

  In a vehicular gate opening / closing device used in an ETC system, a gate (bar) is opened / closed in accordance with payment of a fee, and passage of the vehicle is permitted / not permitted. In such a gate opening / closing device for a vehicle, if the payment of the charge cannot be confirmed, the bar member remains in the passage non-permitted position, but the vehicle may enter (forced approach) nevertheless. .

  Conventionally, a vehicular gate opening / closing device has been proposed in which a bar (blocking bar) can be rotated from a passage non-permitted position (blocking position) to a retracted position on the assumption of such forced entry of the vehicle (for example, Patent Document 1). This conventional gate opening and closing device for a vehicle is configured such that after the bar (blocking bar) is retracted to the retracted position, it does not return from the retracted position.

JP 2005-68886 A

  However, in the conventional gate opening / closing device for a vehicle, a large force is required to return the bar (blocking bar) from the retracted position to the passage non-permitted position (blocking position). That is, the bar (blocking bar) is configured to move to the retracted position with the force when the vehicle collides. Usually, the force required to retract the bar (blocking bar) to the retracted position; The force required to return to the original position is the same. Therefore, if a large force (force when the vehicle collides) is required to retract the bar (blocking bar), the same force (same as the vehicle collides) can be used to return the bar (blocking bar). A large force) is required.

  Therefore, in a conventional gate opening / closing device for a vehicle, if an attempt is made to return the bar (blocking bar) to the original position by automatic control or remote control, a motor with a large output is required, which is difficult to realize with a small motor. There was a problem that there was. If the bar (blocking bar) can be returned to its original position with a force (small force) that can be obtained with a small motor, the force required to retract the bar (blocking bar) to the retracted position is usually Since the force required to return to the original position is the same, this time, there is a problem that the bar (blocking bar) retracts even with a small force (force such as wind).

  The present invention has been made to solve the above-described conventional problems. When the bar member is retracted to the retracted position, the bar member is not retracted unless it receives a certain amount of force (such as a force received when contacting the vehicle). To provide a gate opening / closing device for a vehicle that does not require a large force when returning the bar member to its original position and can return the position of the bar member with a relatively small force (such as a driving force of a motor). With the goal.

  The gate opening / closing device for a vehicle according to the present invention includes a main body unit and a bar unit rotatably attached to a front surface of the main body unit, the bar unit including a bar member for restricting passage of the vehicle, And a bar holding member that holds the bar member, and the bar member is rotatable between a passage non-permission position that blocks passage of the vehicle and a passage permission position that permits passage of the vehicle. In the opening / closing device, the bar holding member includes a storage portion that stores a root end portion of the bar member, and the bar member is in contact with a vehicle when in the passage non-permission position, The root end portion of the bar member can be pulled out of the storage portion and rotated to a retracted position retracted from the traveling path of the vehicle, and the storage portion includes a bending spring having a locking surface portion and an inclined surface portion. Provided A locking step portion and a guide surface portion are provided at the root end portion of the bar member, and when the bar member is in the passage non-permitted position, the root end portion of the bar member is stored in the storage portion. Then, when the locking surface portion is locked to the locking step portion and the bar member is returned from the retracted position to the passage permission position, the guide surface portion gets over the inclined surface portion and the root of the bar member is The end portion can be stored in the storage portion.

  With this configuration, the bar member can be held / released (released). When the bar member is in the passage non-permitted position, the locking surface portion of the bending spring is locked to the locking step portion of the bar member in a state where the root end portion of the bar member is stored in the storage portion of the bar holding member. . In this way, the bar member is held and locked to the bar holding member, and the root end portion of the bar member is made difficult to come out of the storage portion of the bar holding member. Therefore, the root end portion of the bar member does not come out of the storage portion of the bar holding member unless receiving a certain amount of force (such as a force received when the bar member comes into contact with the vehicle). On the other hand, when the bar member is in the retracted position, when the root end portion of the bar member is pushed into the storage portion of the bar holding member, the guide surface portion of the bar member gets over the inclined surface portion of the bending spring, and the root end portion of the bar member is moved. It can be stored in the storage section. In this manner, the bar member is released (released) from the bar holding member, and the root end portion of the bar member easily enters the storage portion of the bar holding member. Therefore, the root end portion of the bar member can be easily stored in the storage portion of the bar holding member with a relatively small force (such as a driving force of the motor).

  Hereinafter, a gate opening and closing device for a vehicle according to an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a case of a vehicle gate opening / closing device used in an ETC system or the like is illustrated.

(First embodiment)
A configuration of a vehicle gate opening / closing device according to a first embodiment of the present invention will be described with reference to the drawings. FIGS. 1-13 is explanatory drawing which shows the gate opening / closing apparatus for vehicles of 1st Embodiment. As shown in FIGS. 1 to 4, the gate opening / closing device 1 for a vehicle has a box-shaped main body unit 2 and a front surface of the main body unit 2 (a surface on which the vehicle is directed, a lower surface in FIG. 3). A bar unit 3 that is rotatably attached and a return unit 4 that is attached to the upper surface of the main unit 2 are provided.

  The bar unit 3 includes a bar member 5 for restricting (permitting / disallowing) the passage of the vehicle and a bar holding member 6 for holding the bar member 5. The bar member 5 is rotatably attached to the bar holding member 6, and the bar holding member 6 is provided with a storage portion 7 for storing the root end portion of the bar member 5 (see FIG. 1). Further, the return unit 4 is provided with an arm member 8 for pushing up the bar member 5 (see FIG. 4).

  Here, with reference to the drawings, the four positions of the bar member 5 of the vehicle gate opening / closing device 1 (passage-not-permitted position, pass-permitted position, retracted position, and return preparation position) will be described. As shown in FIG. 1A, at the passage non-permission position, the bar member 5 is supported so as to be substantially parallel (horizontal) to the ground and substantially perpendicular to the vehicle traveling direction. At this passage non-permitted position, the vehicle is blocked from passing. On the other hand, as shown in FIG. 1B, at the passage permission position, the bar member 5 is supported so as to be substantially perpendicular (vertical) to the ground. At this passage permission position, passage of the vehicle is permitted. The vehicle gate opening / closing device 1 normally rotates (opens / closes) the bar member 5 between the passage-permitted position and the passage-permitted position (that is, when payment has been confirmed by the ETC system). (See FIG. 2). In this operation (bar opening / closing operation), the bar holding member 6 is rotated with respect to the main body unit 2 by the driving force of a motor (not shown) built in the main body unit 2. At this time, the root end portion of the bar member 5 is kept in the storage portion 7 of the bar holding member 6.

  On the other hand, if the payment of the charge could not be confirmed by the ETC system, the bar member 5 remains in the passage-permitted position, but if the vehicle entered (forced approach) nevertheless, The vehicle will come into contact. In such a case, the bar member 5 is rotated from the passage non-permitted position to the retracted position by an impact of contact with the vehicle (see FIG. 3). As shown in FIG. 1C, in the retracted position, the bar member 5 is supported so as to be substantially parallel (horizontal) to the ground and substantially parallel to the vehicle traveling direction. At this retracted position, the bar member 5 is retracted from the traveling path of the vehicle, and the return rotation (rebound rotation) of the bar member 5 is locked. The return rotation lock (return lock) will be described in detail later. In the above operation (bar retracting operation), the bar member 5 is rotated with respect to the bar holding member 6 by the impact force of contact with the vehicle. Therefore, the root end portion of the bar member 5 comes out of the storage portion 7 of the bar holding member 6.

  When returning the bar member 5 from the retracted position, first, as shown in FIG. 4A, the bar member 5 is rotated from the retracted position to the return preparation position. At this time, the bar holding member 6 is rotated with respect to the main unit 2. As shown in FIG. 1D, at the return preparation position, the bar member 5 is supported so as to be substantially parallel (horizontal) to the ground and substantially parallel to the vehicle traveling direction. In this return preparation position, the bar member 5 is supported on the upper side of the main unit 2. In this operation (rotation from the retracted position to the return preparation position), the bar holding member 6 is rotated with respect to the main body unit 2 by the driving force of a motor (not shown) built in the main body unit 2.

  Next, as shown in FIG. 4B, the bar member 5 is rotated from the return preparation position to the passage permission position. At this time, the bar member 5 is rotated with respect to the bar holding member 6 by the bar member 5 being pushed up by the arm member 8 of the return unit 4. When the bar member 5 rotates to the passage permission position, the root end portion of the bar member 5 is stored in the storage portion 7 of the bar holding member 6. In this operation (rotation from the return preparation position to the passage permission position), the arm member 8 is rotated so as to push up the bar member 5 by the driving force of a motor (not shown) built in the return unit 4.

  Here, the characteristic structure of the present invention will be described in detail with reference to the drawings. 5 and 6 show a configuration for holding lock / holding lock release (release) of the bar member 5 in the bar retracting operation. As shown in FIGS. 5 and 6, a pair of bending springs 9 are provided on the inner wall of the storage portion 7 of the bar holding member 6. A locking surface portion 10 is provided at a tip side portion of the bending spring 9, and an inclined surface portion 11 is provided at a root end side portion of the bending spring 9. On the other hand, holding lock members 12 for holding and locking the bar member 5 in the storage portion 7 of the bar holding member 6 are provided on the outer side surfaces on both sides of the root end portion of the bar member 5. A locking step 13 for locking the locking surface 10 of the bending spring 9 is formed at the central portion of the outer surface of the holding lock member 12, and a tip side portion (in FIG. 5) of the holding lock member 12. A guide surface portion 14 that abuts against the inclined surface portion 11 of the bending spring 9 is formed on the lower portion.

  As shown in FIGS. 5A and 6A, when the bar member 5 is held and locked to the bar holding member 6, the locking surface portion 10 of the bending spring 9 is locked to the locking step of the holding lock member 12. The root end portion of the bar member 5 may come out of the storage portion 7 of the bar holding member 6 unless it is locked to the portion 13 and receives a certain large force (the force received when the bar member 5 comes into contact with the vehicle). Absent. In this case, the locking surface portion 10 of the bending spring 9 and the locking step portion 13 of the holding lock member 12 have an angle close to a right angle with respect to the direction in which the root end portion of the bar member 5 comes out (upward direction in FIG. 5). For example, it is set to 90 degrees to 80 degrees or the like, and the root end portion of the bar member 5 is difficult to come out of the storage portion 7 of the bar holding member 6. When a certain amount of force (force received when the bar member 5 comes into contact with the vehicle) is received, the bar member 5 is stored in the storage portion 7 of the bar holding member 6 as shown in FIGS. 5B and 6B. The holding lock is released.

  On the other hand, when the bar member 5 is held and locked to the bar holding member 6 from the state in which the holding lock is released, the bar member 5 is rotated with respect to the bar holding member 6 around the rotation shaft 15, and the bar member 5 is rotated. 5 is pushed into the storage portion 7 of the bar holding member 6. At this time, the guide surface portion 14 of the holding lock member 12 can easily get over the inclined surface portion 11 of the bending spring 9. In this case, the inclined surface portion 11 of the bending spring 9 and the guide surface portion 14 of the holding lock member 12 are inclined with respect to the direction in which the root end portion of the bar member 5 is pushed (downward direction in FIG. 5) (for example, 40 The root end portion of the bar member 5 can easily enter the storage portion 7 of the bar holding member 6.

  7 to 13 show a configuration for returning lock / returning lock release of the bar member 5 after the bar retracting operation. Here, with reference to FIGS. 7-10, the structure for the return lock of the bar member 5 is demonstrated first. As shown in FIGS. 7 and 8, a flap plate 16 for return locking is attached to the lower surface of the bar member 5 (the lower surface in FIG. 8A). On the other hand, a return lock unit 17 is attached to the lower part of the bar holding member 6 (lower part in FIG. 8).

  The flap plate 16 is provided with a guide contact portion 19 with which the lock guide member 18 provided on the return lock unit 17 contacts, and a guide relief hole 20 into which the tip of the lock guide member 18 falls. A leaf spring 21 is attached to the inside of the flap plate 16, and the flap plate 16 is biased by a spring elastic force in a direction away from the bar member 5. Further, the flap plate 16 is provided with a lock piece 23 that is engaged with the lock groove 22 of the return lock unit 17. Further, the flap plate 16 is provided with a long hole 25 into which the slide pin 24 provided on the bar member 5 is inserted.

  As shown in FIG. 9, when the bar member 5 is only rotated within a predetermined angle range (for example, 0 to 89 degrees) with respect to the bar holding member 6 after the bar retracting operation is started, the return lock unit. The 17 lock guide members 18 are in contact with the guide contact portion 19 of the flap plate 16. Thereafter, as shown in FIG. 10, when the bar retracting operation proceeds and the bar member 5 rotates to the maximum angle range (for example, 90 degrees) with respect to the bar holding member 6, the lock guide member of the return lock unit 17. 18 is in a state where it falls into the guide relief hole 20 of the flap plate 16.

  When the lock guide member 18 of the return lock unit 17 falls into the guide relief hole 20 of the flap plate 16, the flap plate 16 receives the urging force (spring elastic force) of the leaf spring 21 and moves away from the bar member 5 (see FIG. 10 (to the right). Further, the flap plate 16 slides downward with respect to the bar member 5 (downward in FIG. 10) in response to a force such as a centrifugal force generated by the bar retracting operation. At this time, the slide pin 24 slides in the long hole 25 of the flap plate 16. As a result, as shown in FIG. 10, the lock piece 23 of the flap plate 16 is engaged with the lock groove 22 of the return lock unit 17, and the return lock of the bar member 5 is performed.

  Next, a configuration for releasing the return lock of the bar member 5 will be described with reference to FIGS. As shown in FIG. 11, the return lock release of the bar member 5 is performed during the bar return operation. As shown in FIGS. 12 and 13, the flap plate 16 is provided with a guide groove 27 for guiding a guide pin 26 provided on the bar member 5.

  When the bar return operation is performed and the flap plate 16 is pushed up by the arm member 8 of the return unit 4, the flap plate 16 slides in a direction approaching the bar member 5. Further, the flap plate 16 receives a reaction force when the guide pin 26 is guided by the guide groove 27, and slides in a direction to return to the original position (right direction in FIG. 12) (see FIGS. 12 and 13). ). At this time, the slide pin 24 slides in the long hole 25 of the flap plate 16. As a result, as shown in FIG. 13, the locking of the lock piece 23 of the flap plate 16 to the lock groove 22 of the return lock unit 17 is released, and the return lock of the bar member 5 is released.

  In the present embodiment, as shown in FIG. 8, the bar member 5 includes a base portion 28 and a cover portion 29, and the cover portion 29 is detachable from the base portion 28. The bar holding member 6 (return lock unit 17) is provided with a retaining pin 31 that is inserted into a pin hole 30 provided in the base portion 28 and the cover portion 29. Therefore, in a state where the retaining pin 31 is inserted into the pin hole 30 of the base portion 28 and the cover portion 29, the cover portion 29 cannot be removed from the base portion 28. On the other hand, as shown in FIG. 11, when the bar return operation is performed and the flap plate 16 is pushed up by the arm member 8 of the return unit 4, the retaining pin 31 is connected to the pin hole 30 of the base portion 28 and the cover portion 29. The cover part 29 can be removed from the base part 28 by slipping out of the base part 28.

  According to the vehicle gate opening / closing apparatus 1 of the first embodiment of the present invention, when the bar member 5 is retracted to the retracted position, a certain amount of force (such as force received when contacting the vehicle) is applied. However, when the bar member 5 is returned to the original position, a large force is not required, and the position of the bar member 5 can be returned with a relatively small force (such as a motor driving force).

  That is, in the present embodiment, the bar member 5 can be held / released (released). When the bar member 5 is in the passage-permitted position, the locking surface portion 10 of the bending spring 9 locks the bar member 5 while the root end portion of the bar member 5 is stored in the storage portion 7 of the bar holding member 6. Locked to the step 13. In this way, the bar member 5 is held and locked to the bar holding member 6, so that the root end portion of the bar member 5 is difficult to come out of the storage portion 7 of the bar holding member 6. Therefore, the root end portion of the bar member 5 does not come out of the storage portion 7 of the bar holding member 6 unless a certain amount of force (such as a force received when the bar member 5 comes into contact with the vehicle) is received. On the other hand, when the bar member 5 is in the retracted position, when the root end portion of the bar member 5 is pushed into the storage portion 7 of the bar holding member 6, the guide surface portion 14 of the bar member 5 gets over the inclined surface portion 11 of the bending spring 9. The root end portion of the bar member 5 can be stored in the storage portion 7. In this way, the holding lock is released (released) from the bar holding member 6 so that the root end portion of the bar member 5 can easily enter the storage portion 7 of the bar holding member 6. Therefore, the root end portion of the bar member 5 can be easily stored in the storage portion 7 of the bar holding member 6 with a relatively small force (such as a driving force of the motor).

  Further, in the present embodiment, the return lock / return lock release of the bar member 5 becomes possible. When the bar member 5 is in the retracted position, the lock piece 23 is engaged with the lock groove 22 and the return lock of the bar member 5 is performed. On the other hand, when the bar member 5 is rotated from the retracted position to the passage permission position, the locking of the lock piece 23 and the lock groove 22 is released, and the return lock is released. Thus, by performing the return lock of the bar member 5, it is possible to prevent the bar member 5 from returning and rotating and colliding with a side surface of the vehicle body or a window.

  Further, in the present embodiment, when the bar member 5 rotates from the passage-permitted position to the retracted position, the lock guide member 18 contacts the guide contact portion 19 of the flap plate 16, and the bar member 5 moves to the retracted position. When the rotation to is completed, the lock guide member 18 falls into the guide relief hole 20 of the flap plate 16. At this time, the flap plate 16 moves in a direction away from the bar member 5 due to the spring ineffective force, and the lock piece 23 is engaged with the lock groove 22 so that the bar member 5 can be returned and locked. On the other hand, when the bar member 5 is rotated from the retracted position to the passage permission position, the flap unit 16 is pushed in the direction approaching the bar member 5 by the return unit 4, and the lock piece 23 and the lock groove 22 are locked. Once released, the return lock can be released.

  Further, in the present embodiment, when the bar member 5 completes the rotation to the retracted position, the slide pin 24 slides in the elongated hole 25, and the lock piece 23 is locked in the lock groove 22, and the bar The return lock of the member 5 becomes possible.

  In this embodiment, when the bar member 5 is rotated from the retracted position to the passage permission position, when the flap plate 16 is pushed in the direction approaching the bar member 5 by the return unit 4, the guide pin 26 is guided.
