Description

  The present invention relates to a passage opening and closing device, and more particularly to a passage opening and closing device having a mechanism in which a door member expands and contracts when opening and closing.

In recent years, gates for automatically controlling the entry and exit of users are often provided at the entrances and exits of station buildings, amusement parks, large-scale facilities, and the like. These gate devices are configured to open and close a door member provided in the gate device by reading information recorded on an admission ticket or an IC card and judging whether or not to enter. In addition, for the user who passes through the passage, the width of the passage is designed to allow the adult to pass with a margin. Therefore, the length of the door member is configured to cover the entire width of the passage when the passage is closed. In other words, when the door member is opened, it is necessary to store the door member in its length on the gate device main body side. For this reason, the length direction dimension of a gate apparatus main body needs more than the length of a door member. Further, when entering / exiting (two-way traffic) with one gate device, the gate device needs to be rotated within a range of about 180 degrees, so that the length of the gate device main body is further increased. It is necessary to secure a large space for installing the.
In order to reduce the size of the gate device described above, Patent Document 1 discloses a security gate that reduces the size in the thickness direction of the gate device and ensures safety when an excessive force is applied to the door. ing.

However, the prior art disclosed in Patent Document 1 is based on the folding direction of the door member according to the difference in the user's traveling direction in order to reduce the dimension in the thickness direction of the gate device and ensure safety. There is a problem that the mechanism is complicated and the maintenance cost increases.
The present invention has been made in view of such problems, and includes an opening / closing unit having a door member that is supported by the passage opening / closing device body and moves between the passage opening position and the passage closing position. The size of the passage opening / closing device body in the length direction is reduced by extending and contracting the protrusion length into the passage while rotating between the passage opening position and the passage closing position about the rotation axis, It is an object of the present invention to provide a passage opening and closing device that simplifies the expansion and contraction mechanism and suppresses maintenance costs.

In order to solve such a problem, the present invention provides a passage opening and closing device that determines whether or not a passage target is allowed to pass through a passage and controls the opening and closing of the passage, at least on one side of the passage. A disposed passage opening / closing device main body, a door member that is supported by the passage opening / closing device main body and that opens / closes between a passage opening position retracted from the passage and a passage closing position protruding into the passage. An opening / closing unit and an opening / closing drive mechanism for driving the opening / closing unit to open / close, wherein the door member rotates between the passage opening position and the passage closing position about a rotation shaft. It is characterized by extending and contracting the protruding length to the.
The passage opening / closing device of the present invention includes an opening / closing unit supported by a passage opening / closing device body, and the opening / closing unit includes a door member that opens and closes to a passage opening position and a passage closing position. The projection length into the passage is expanded and contracted while rotating around the center. That is, when the opening / closing unit is in the passage closing position, the protruding length of the door member is extended, and when the opening / closing unit is in the passage opening position, the protruding length of the door member is reduced. Thereby, the dimension of the length direction of a channel | path opening / closing apparatus can be shortened.

According to a second aspect of the present invention, the opening / closing unit includes the rotation shaft that is rotated by the opening / closing drive mechanism, and a first door member that is fixed to the rotation shaft and that opens and closes with the rotation of the rotation shaft. An operating mechanism that is supported by the first door member and that operates by receiving the rotational force of the rotating shaft; and a second that moves forward and backward in the direction parallel to the first door member by the operation of the operating mechanism. A door member, and when the opening / closing unit is in the passage opening position, the second door member is retracted to a shortened position overlapping the first door member, and the opening / closing drive mechanism closes the passage. The second door member that was in the retracted position when the rotation shaft is rotated in the direction to move is rotated in the closing direction together with the first door member, and the first mechanism is operated by the operation mechanism. It moves to the extended position which protruded from the door member.
The opening / closing unit of the present invention includes two door members and an operating mechanism. That is, a first door member that is fixed to the rotation shaft and opens and closes together with the rotation of the rotation shaft, an operation mechanism that converts the rotation operation of the rotation shaft into an advance / retreat operation, and the first door by this operation mechanism A second door member that advances and retreats in a direction parallel to the member is integrally configured. With this configuration, when the opening / closing unit opens the passage, the two door members are retracted to the overlapping position, and when the opening / closing unit is rotated to the position for closing the passage, the two door members are closed. The second door member protrudes from the first door member while rotating in the direction. Thereby, when the opening / closing unit is opened, the length of the passage opening / closing device main body can be reduced to the length of the first door member.

According to a third aspect of the present invention, the operating mechanism is engaged with a rotational force transmitting member that is driven by receiving the rotational force of the rotating shaft, a pinion gear that rotates by receiving the driving force from the rotational force transmitting member, and the pinion gear. A rack gear member that linearly reciprocates in response to the rotational force of the pinion gear, and a part of which is pivotally supported by the first door member to convert the linear motion of the rack gear member into a swinging motion. And a swing lever that moves the second door member back and forth between the shortened position and the extended position.
The most important feature of the present invention is that the second door member is converted into a movement in the advancing / retreating direction by an operating mechanism using the rotational force of the rotating shaft. That is, the operating mechanism transmits the rotational force of the rotation shaft to the pinion gear by the rotational force transmission member. The rotational force of the pinion gear is converted into a linear reciprocating motion by the rack gear portion. Since the operating range of the reciprocating motion of the rack gear portion is small, it is amplified by a swing lever and converted into a swing motion. Since the second door member is attached to the swing lever, the second door member can be moved back and forth between the shortened position and the extended position by the swing motion of the swing lever. As a result, a slight rotational force of the rotating shaft can be amplified and converted into a swinging motion.

According to a fourth aspect of the present invention, the opening / closing drive mechanism continuously advances and retracts the second door member between the shortened position and the extended position according to a rotation angle of the rotation shaft. .
The rotation of the rotating shaft is continuously transmitted to the pinion gear via the rotational force transmitting member. Therefore, since the continuous change in the rotation angle of the rotation shaft is directly transmitted to the pinion gear, the advancement / retraction of the second door member continuously operates in conjunction with the rotation angle of the rotation shaft. Thereby, the 2nd door member can be operated smoothly.

According to the present invention, the protrusion length of the door member is extended when the opening / closing unit is in the passage closing position, and the protrusion length of the door member is reduced when the opening / closing unit is in the passage opening position. The dimension in the vertical direction can be shortened.
Further, when the opening / closing unit opens the passage, the two door members are retracted to the overlapping position, and when the opening / closing unit is rotated to the position for closing the passage, the two door members are rotated in the closing direction. Since the second door member protrudes from the first door member while moving, when the opening / closing unit is opened, the size of the passage opening / closing device body in the length direction is reduced to the length of the first door member. Can do.
Further, since the second door member is attached to the swing lever, the second door member can be moved back and forth between the shortened position and the extended position by the swing motion of the swing lever. As a result, a slight rotational force of the rotating shaft can be amplified and converted into a swinging motion.
In addition, since the continuous change in the rotation angle of the rotation shaft is directly transmitted to the pinion gear, the advancement / retraction of the second door member continuously operates in conjunction with the rotation angle of the rotation shaft. Thereby, the 2nd door member can be operated smoothly.

Next, a series of operations of the passage opening and closing device 50 of the present invention will be described.

FIG. 1A is a diagram showing a state in which the opening / closing unit 51 of the passage opening / closing device 50 is in the passage closing position. At this time, the first door member 4 is positioned substantially orthogonal to the passage opening / closing device main body 1. The second door member 5 supported by the first door member 4 is in the most extended position and closes the passage 9. In this state, when the passing object 7 brings an IC card (not shown) close to the reader / writer 6, a control device (not shown) verifies the recorded information read from the reader / writer 6 and determines whether or not the passing is permitted.
In FIG. 1B, when the control device permits the passage, it is determined that the passage target 7 advances from the direction of the thick arrow (the lower side in the figure), and the opening / closing drive mechanism (not shown) is operated to move the rotating shaft 3. By turning in the opening direction indicated by the arrow B, the opening / closing unit 51 is opened so as not to prevent the traveling object 7 from proceeding. At that time, the opening / closing unit 51 opens while the second door member 5 moves in the direction of arrow A (reduction direction). Note that the determination of the traveling direction of the passage object 7 can be made based on which of the two reader / writers 2 and 6 has read the recorded information.

In FIG. 1C, the opening / closing unit 51 is completely stored in the passage opening / closing apparatus main body 1 (retracted from the passage 9), and the passage 9 is opened.
