Abstract

<P>PROBLEM TO BE SOLVED: To more surely prevent a return rotation of a gate arm from its retreating position in a simple structure, in an open/close device for a gate for a vehicle in which the gate arm is rotatable to the retreating position. <P>SOLUTION: In an interception position indicated by a solid line, a shaft center O<SB>2</SB>of a hinge pin allowing the gate arm 34 to rotate to the retreating position indicated by a chain line in Fig.(b) is inclined in a passing direction of the vehicle by a predetermined angle of inclination when the vehicle running on a running road 14 in its advancing direction indicated by an arrow A collides against the gate arm 34. The gate arm 34 is inclined obliquely downward while rotating toward the retreating position, and the bounce is restrained since a momentum to rotate the gate arm 34 toward the retreating position works due to a force of gravity. In cooperation with the mechanical engagement by means of a stopper device 46, the return rotation caused by the bounce of the gate arm 34 from its retreating position is more surely prevented. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a vehicular gate opening / closing device, and more particularly to an improvement in a vehicular gate opening / closing device in which a blocking bar for blocking the passage of a vehicle can be rotated in the passing direction of the vehicle.

  A blocking position for supporting the longitudinal blocking rod in a cantilevered manner, and holding the blocking rod in a substantially horizontal position through the supporting member to block the vehicle from passing; For example, a gate opening / closing device for a vehicle that moves to an open position that permits the use of a toll is used in a toll road or a toll gate of a parking lot. In such a vehicle gate opening / closing device, in order to prevent the vehicle and the opening / closing device from being damaged when the vehicle collides with the blocking rod at the blocking position, the blocking rod is rotated around the hinge pin in the substantially vertical direction. At the blocking position, the blocking rod is normally held at a blocking position protruding so as to block the passage of the vehicle, but when a predetermined evacuation load is applied in the passing direction of the vehicle. For example, Patent Document 1 proposes providing a retracting device that allows the hinge pin to rotate to a retracted position that rotates in the passing direction.

JP 2001-226923 A

  However, even in the gate opening / closing device for a vehicle provided with such a retracting device, there is a possibility that the blocking rod that has been rotated to the retracted position will bounce back and rotate, and collide with the side surface of the vehicle or the window. It is conceivable to provide a stopper device that mechanically prevents the return rotation of the blocking rod when the blocking rod is rotated to the retracted position, but depending on the degree of collision, that is, the rotation speed of the blocking rod. It is difficult to reliably prevent return rotation due to damage or deformation, and the use of a large, high-strength stopper device increases the manufacturing cost.

  The present invention has been made against the background of the above circumstances. The object of the present invention is to provide a vehicle gate opening / closing device in which the blocking bar can be rotated to the retracted position. An object of the present invention is to more reliably prevent the return rotation with a simple configuration.

  In order to achieve such an object, the first invention has (a) a support member that cantilever-supports a long blocking bar, and the blocking bar is placed in a substantially horizontal posture through the support member. And a moving device that moves to a blocking position that holds and prevents the vehicle from passing, and an open position that allows the vehicle to pass, and (b) a hinge pin that rotatably attaches the blocking bar to the support member. In the blocking position, normally, the blocking rod is held at a blocking position protruding so as to block the passage of the vehicle. When a predetermined evacuation load acts in the passing direction of the vehicle, the passing direction around the hinge pin (C) the hinge pin is configured such that the upper part in the vertical direction at the blocking position is the passing direction of the vehicle, There is characterized in that it is arranged in a posture which is inclined to the roadway opposite side of the vehicle.

  According to a second aspect of the present invention, in the gate opening and closing device for a vehicle according to the first aspect of the present invention, the blocking bar is disposed across the blocking member and the support member, and the blocking rod is rotated from the blocking position to the retracted position. And a stopper device that mechanically engages the blocking bar and the support member to prevent the blocking bar from rotating back toward the blocking position.

  In such a vehicular gate opening / closing device, the hinge pin that allows the blocking bar to rotate to the retracted position at the shut-off position is inclined such that the upper part in the vertical direction is the vehicle passing direction or the opposite side of the vehicle traveling path. Since the blocking bar is inclined obliquely downward as it rotates in the retracted position, the protrusion side (tip side) is longer than the hinge pin and the center of gravity is located on the protrusion side. Therefore, a moment that rotates in the direction of the retracted position due to gravity acts. Therefore, the return rotation due to the rebound from the retracted position is suppressed, and re-collision with the side surface of the vehicle, the window, etc. is avoided or reduced, and it is only necessary to incline the attitude of the hinge pin. The In particular, in the case of inclining in the passing direction of the vehicle, it is only necessary to incline the entire body including the support member and the blocking bar, so that it can be easily applied to the conventional apparatus without requiring a significant design change.

  The second invention is a combination of a stopper device that mechanically prevents the return rotation of the blocking rod, and in combination with the inclination of the hinge pin, the return rotation of the blocking rod is more reliably prevented, and a small and inexpensive stopper. The device can be adopted.

  The moving device, for example, reciprocally rotates the support member around a substantially horizontal opening / closing axis, and includes a blocking bar disposed on the supporting member so as to protrude in a direction substantially perpendicular to the opening / closing axis. It is configured with an electric motor so that it can be rotated to a horizontal blocking position and an open position that is rotated upward. Various modes such as a moving object can be adopted.

  For example, the position where the blocking bar protrudes substantially right is appropriate, but the opening position is appropriately determined within a range that does not hinder the traveling of the vehicle. As for the retreat position, a position that is rotated approximately 90 ° from the blocking position and is approximately parallel to the traveling path of the vehicle is appropriate, but is appropriately determined within a range that allows the vehicle to pass.

  The retracting device normally holds the blocking bar at the blocking position, but when the predetermined retracting load is applied, the blocking bar is positioned at the blocking position by, for example, a spring so that the blocking bar can be rotated to the retracted position. It is configured with a moderation device that allows free rotation when it is detached from the position.

  For example, the hinge pin is inclined in the vehicle passing direction (traveling direction) in a vertical plane parallel to the traveling path, that is, in a vertical plane parallel to the traveling path (in the state shown in FIG. 2), and in a vertical plane perpendicular to the traveling path. In the state shown in FIG. 1 (a), it is arranged so as to be held substantially vertically, but in the vertical plane perpendicular to the road (in the state shown in FIG. 1 (a)), the upper part is opposite to the road. It can also be disposed so as to be held substantially vertically in a vertical plane (state shown in FIG. 2) that is inclined to the side and parallel to the passing direction of the vehicle. In the vertical plane parallel to the passing direction of the vehicle (state of FIG. 2), the upper part is inclined in the passing direction (traveling direction) of the vehicle and in the vertical plane perpendicular to the traveling path (in FIG. 1 (a)). In the state), the upper part can be disposed in a posture in which the upper part is inclined to the opposite side of the traveling path. In short, the position of the hinge pin is such that the blocking bar, which is held in a substantially horizontal position at the blocking position, tilts downward as it is rotated toward the retracted position side, that is, the vehicle passing direction. For example, in the vertical plane perpendicular to the road (state shown in FIG. 1 (a)), even if the upper part is inclined toward the road, the vertical plane parallel to the passing direction of the vehicle (see FIG. In the state (2), the upper part is inclined in the vehicle passing direction (traveling direction), so that the blocking bar may be inclined downward along with the rotation toward the retracted position.

  The inclination angle of the hinge pin can be set as appropriate as long as the blocking bar does not interfere with the road surface or the like. For example, the inclination angle of the hinge pin is determined within a range of several degrees to several tens of degrees.

  In the stopper device of the second invention, the blocking bar is mechanically engaged with the blocking bar by rotating the blocking bar to the retracted position by an urging force such as a spring or gravity, and the blocking bar is blocked. It is configured so as to prevent it from rotating back to the position side, and various modes such as an engagement pin, a hook, and a ratchet are possible. In implementing the first invention, such a stopper device is not necessarily required, and an electrically controlled stopper device, a brake device, or the like can be used in combination.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a state in which a pair of vehicle gate opening and closing devices 10 and 12 according to an embodiment of the present invention are disposed on both sides of a vehicle traveling path 14 such as a toll gate on a highway. a) is a front view perpendicular to the traveling road 14 and viewed from the same direction as the traveling direction of the vehicle, (b) is a plan view, and a white arrow A in (b) represents the traveling direction of the vehicle. Each of the gate opening / closing devices 10 and 12 for a vehicle is provided with opening and closing arms 16 and 18, respectively, and as shown by a solid line, the vehicle passes at a blocking position that protrudes toward the traveling road 14 at a substantially horizontal position and substantially perpendicular to the traveling road 14. On the other hand, by turning the open / close arms 16 and 18 to the open position projecting upward as shown by the one-dot chain line in FIG. Is acceptable. Since these vehicle gate opening and closing devices 10 and 12 are configured substantially symmetrically and have substantially the same configuration, the right vehicle gate opening and closing device 10 will be described in detail below, and the left vehicle The gate opening / closing device 12 is denoted by the same reference numeral, and detailed description thereof is omitted. Note that the traveling path 14 can be configured to be opened and closed with only one of the gate opening / closing devices 10 or 12 for a vehicle, and is not necessarily provided in pairs.

The vehicular gate opening / closing device 10 is mainly composed of the opening / closing arm 16 and the main body case 20, and the main body case 20 controls the electric servomotor 22 functioning as a moving device and the operation of the electric servomotor 22. A control panel, a control circuit, and the like are disposed. Then, the open / close arm 16 is reciprocally rotated in an angle range of about 90 ° around the open / close axis O ₁ which is substantially horizontal and parallel to the travel path 14 by the electric servo motor 22 via the rotation shaft 24 shown in FIG. And rotated to the blocking position and the opening position. The opening / closing axis O ₁ corresponds to the axis of the rotating shaft 24, and the opening / closing arm 16 projects in a direction substantially perpendicular to the opening / closing axis O ₁ and is integrated with the tip of the rotating shaft 24 by a bolt or the like. Fixed. The rear end portion of the opening and closing arm 16, i.e. on the opposite side of the opening and closing axis O _1, the balance weight 26 for a load of about opening and closing axis O ₁ substantially uniformly are provided.

3 is a plan view in which a part of the opening / closing arm 16 is cut out. FIGS. 4 to 8 are cross sections taken along lines IV-IV, VV, VI-VI, VII-VII and VIII, respectively, in FIG. It is a figure which shows -VIII cross section, and the opening-and-closing arm 16 is comprised including the support member 30, the connection member 32, and the blocking bar 34. FIG. In these drawings, the opening / closing arm 16 is fixed to the rotary shaft 24 in a posture orthogonal to the opening / closing axis O ₁ through the support member 30 in a state where the opening / closing arm 16 is held at the blocking position. In addition, as is apparent from FIG. 4, in the vertical plane parallel to the axial direction of the rotating shaft 24, that is, the passing direction of the vehicle, the upper portion has a predetermined inclination angle toward the passing direction (traveling direction) of the vehicle. It is arranged in a posture inclined by θ (for example, about 5 °). The balance weight 26 is integrally attached to the support member 30.

The support member 30 has a substantially U-shaped cross section, and is disposed in a posture that opens in a direction opposite to the vehicle passing direction. 3 and 5 are arranged so as to overlap in parallel, and rotate around a retraction axis O _2, which is the axis of the hinge pin 36, via the hinge pin 36 at the tip of the support member 30 as shown in FIGS. Connected as possible. A blocking bar 34 is integrally fixed to the connecting member 32 in a cantilevered manner, and the blocking bar 34 rotates around the retraction axis O ₂ together with the connecting member 32 with respect to the support member 30. It is possible to rotate from the blocking position indicated by the solid line in FIGS. 1B and 3 to the retracted position indicated by the alternate long and short dash line. The blocking position is a position where the connecting member 32 overlaps in parallel with the support member 30 and the blocking bar 34 protrudes in a horizontal direction substantially perpendicular to the opening / closing axis O ₁ to block the passage of the vehicle, and the retracted position is As shown in FIG. 1 (b) by the alternate long and short dash line and as shown in FIG. 2, the blocking bar 34 is rotated approximately 90 ° in the vehicle passing direction and is substantially parallel to the traveling path 14. FIG. 2 is a side view of the vehicle gate opening / closing device 10 as viewed from the traveling road 14 side, and is a view showing a state where the blocking bar 34 is rotated to the retracted position.

  The hinge pin 36 is disposed on a pair of brackets 38 fixed to the support member 30 and rotatably supports the connecting member 32 via the bracket 40. In the parallel vertical plane (state of FIGS. 2 and 5), the upper portion is inclined at the inclination angle θ in the vehicle passing direction (traveling direction), and in the vertical plane perpendicular to the travel path 14 (FIG. 1). In the state (a), it is disposed in a substantially vertical posture. Therefore, the blocking bar 34 is tilted downward as it is rotated from the blocking position to the retracted position, and is moved downward at the same angle as the tilt angle θ as shown in FIG. Tilted to.

  As shown in FIG. 4, the support member 30 is provided with a pair of moderation devices 42, and a ball at the tip is urged by a built-in spring in a direction parallel to the hinge pin 36 and fixed to the connecting member 32. By pressing and engaging the recess of the positioning block 44, the connecting member 32 is positioned at the blocking position with a predetermined positioning load. As a result, the connecting member 32 and the blocking bar 34 are normally held at the blocking position for blocking the passage of the vehicle, and a predetermined retracting load corresponding to the positioning load is applied to the vehicle by, for example, the vehicle colliding with the blocking bar 34. The ball of the moderation device 42 is allowed to move away from the recess of the positioning block 44 and the connecting member 32 is allowed to rotate around the hinge pin 36. The moderation device 42 constitutes a retracting device together with the hinge pin 36, and thus the blocking bar 34 is rotated to the retracted position, whereby damage to the vehicle and the vehicle gate opening / closing device 10 is suppressed.

  Further, the retracted position is defined by the contact of the connecting member 32 to the bracket 38, and the stopper device 46 provided on the support member 30 as shown in FIG. It has been stopped. Similarly to the moderation device 42, the stopper device 46 urges the engaging pin 48 in a direction parallel to the hinge pin 36 by a built-in spring and presses it against the connecting member 32. The connecting member 32 reaches the vicinity of the retracted position. Then, the engagement with the connecting member 32 is released, and the engaging pin 48 protrudes as shown by a one-dot chain line, and is engaged with the connecting member 32 when the connecting member 32 bounces back from the retracted position and rotates. This prevents the return rotation.

  As shown in FIG. 6, the blocking bar 34 is integrally fixed to the aggregate 50 made of light metal such as square tube-shaped FRP (fiber reinforced plastic) or aluminum, and the periphery of the aggregate 50 by insert molding. The one end part of the aggregate 50 protrudes outside from the foamed polystyrene 52 and is fixed to the connecting member 32. The aggregate 50 has substantially the same size as the inside dimension of the U-shaped connecting member 32 and is positioned by being fitted inside the connecting member 32. The foamed polystyrene 52 is connected to the connecting member 32 in the longitudinal direction. It is prescribed | regulated by contact | abutting to the front-end | tip. Further, the width dimension (the dimension in the left-right direction in FIG. 7) of the aggregate 50 is slightly larger than the inner dimension of the connecting member 32, protrudes toward the U-shaped opening side, and is pressed by the flat lid member 54. Thus, the connecting member 32 is integrally fixed.

  As shown in FIG. 8, the lid member 54 is rotatably attached to a hinge pin 56 disposed on the connecting member 32, and is brought into close contact with the aggregate 50 protruding toward the opening side of the connecting member 32. It is like that. The hinge pin 56 is disposed in parallel with the hinge pin 36. In addition, as shown in FIG. 7, a clamp screw 58 is inserted into a through hole provided in the lid member 54, the aggregate 50, and the connecting member 32, and screwed into a nut 60 fixed to the connecting member 32. As a result, the aggregate 50 (blocking bar 34) together with the lid member 54 is integrally fixed to the connecting member 32 so as not to be extracted. A handle 62 is integrally provided on the clamp screw 58, and the lid member 54 is opened and closed by gripping and rotating the handle 62, and the blocking bar 34 is connected from the left in FIG. The blocking bar 34 can be easily and quickly attached to and detached from the connecting member 32 by being inserted into the inside 32 and withdrawn leftward.

  Here, in this embodiment, the hinge pin 36 that allows the blocking bar 34 to rotate to the retracted position in the blocking position is disposed in a posture that is inclined at an inclination angle θ in the passing direction of the vehicle. As shown in FIG. 4, the blocking bar 34 is inclined obliquely downward along with the rotation in the retracted position direction, and a moment that rotates in the retracted position direction due to gravity acts, so that the return rotation due to the rebound is performed. It is suppressed. The blocking bar 34 is rotated around the hinge pin 36 integrally with the connecting member 32, but the length of the protruding side, that is, the side where the foamed polystyrene 52 of the blocking bar 34 is provided is sufficiently longer than the hinge pin 36. In addition, since the center of gravity is located on the protruding side, a moment that rotates in the direction of the retracted position due to gravity acts.

  Further, since the stopper device 46 for mechanically blocking the return rotation of the blocking bar 34 by the engagement pin 48 is provided, the return rotation of the blocking bar 34 is more reliably prevented in combination with the inclination of the hinge pin 36, It is satisfactorily avoided that the blocking bar 34 collides with the side surface of the vehicle, the window, or the like due to the return rotation by the rebound from the retracted position. In this case, since gravity acts on the blocking bar 34 toward the retracted position, the force in the rebounding direction (return rotation) is weakened, and a small and inexpensive stopper device 46 can be adopted, and the hinge pin Since it is only necessary to incline the posture of 36, the apparatus is configured simply and inexpensively as a whole.

  Further, in this embodiment, when the opening / closing arm 16 including the blocking bar 34 is attached to the rotating shaft 24, it is only necessary to incline in the vehicle passing direction as shown in FIG. Can be used, and can be easily applied to conventional devices without requiring significant design changes.

In the above-described embodiment, the hinge pin 36 is inclined in the vehicle passing direction. However, as shown in FIG. 9, the retraction axis O ₂ , which is the axis of the hinge pin 36, is arranged on the upper side with the traveling path 14 of the vehicle. Even if it is inclined to the opposite side, the blocking bar 34 is inclined obliquely downward with the rotation in the retracted position direction, and the same effect as in the above embodiment can be obtained.

  In the above embodiment, the blocking bar 34 rotated toward the retracted position is directly brought into contact with the bracket 38. However, as shown in FIG. 10, urethane rubber, hydraulic type, gas pressure type, etc. The shock absorbing damper 70 such as a shock absorber is disposed on the bracket 38 or the like, and the blocking rod 34 is brought into contact with the shock absorbing damper 70 immediately before reaching the retracted position, thereby absorbing the kinetic energy of the blocking rod 34. Thus, the rebound from the retracted position can be more effectively suppressed. In that case, since the impact acting on the stopper device 46 due to the rebound is further reduced, the stopper device 46 can be more reliably prevented from being damaged, and a smaller and cheaper stopper device 46 can be adopted. Such a shock absorbing damper 70 only needs to be provided across the blocking bar 34 and the support member 30 and can also be disposed on the blocking bar 34 side.

  As mentioned above, although the Example of this invention was described in detail based on drawing, these are one Embodiment to the last, This invention is implemented in the aspect which added the various change and improvement based on the knowledge of those skilled in the art. be able to.
