  In this example, the support 2 accommodates an elastic force applying means 9, an arm rotating means 8 and a resistance applying means 10. The support 3 has an elastic force configured in the same manner as the elastic force applying means 9. The applying means is accommodated, but this may be reversed, and the support 3 is also configured in the same manner as the arm rotating means and the resistance applying means 10 configured in the same manner as the arm rotating means 8. There may be provided a resistance applying means. In addition, since the elastic force provision means (not shown) provided in the support | pillar 3 side is comprised similarly to the elastic force provision means 9, the detailed description is abbreviate | omitted.

  The arm means 4 disposed on the column 2 side in the lateral direction is mounted on the column 2 at one end 31 via a rotation shaft 33 so as to be rotatable in the A and B directions in the vertical plane. An arm member 34 having a rectangular cross section fixed to the door 6 at the end 32 is provided. The arm member 34 is fixed to a rotating shaft 33, and the rotating shaft 33 is supported by the support column 2 via a bearing or the like so as to be rotatable. Since the arm means 5 disposed on the support column 3 side in the lateral direction is configured in the same manner as the arm means 4, detailed description thereof is omitted.

  The door 6 includes a frame body 41 having a rectangular shape when viewed from the front, and a large number of blind lattices 42 attached to the frame body 41. For example, instead of the horizontal lattice 42, the door 6 is attached to the frame body 41. A large number of vertical lattices may be provided.

  For example, as shown in FIG. 3, the arm rotation means 8 includes the electric motor 7 and a transmission means 71 that transmits the rotation of the output rotation shaft of the electric motor 7 to the arm means 4. The electric motor 7 is attached to the column 2.

Note that the speed reduction mechanism 76 may include a tooth row 74 formed on the peripheral edge located on the spiral gear 73 side of the cam plate 51 instead of the gear 75.

  In addition to the above-described configuration, the arm rotation means 8 is configured to reach the position immediately before the fully opened door of the door 6 that moves toward the fully opened position by the rotation of the arm means 4 and 5 in the A direction, and the arm means 4. And the arrival detection means 14 for detecting the arrival of the door 6 that moves toward the fully closed position by the rotation in the B direction to the position immediately before the fully closed position, respectively. Based on this, the operation of the electric motor 7 is controlled. For example, as shown in FIG. 10, the arrival detection means 14 is attached to the support plate 2 and the circular plate 82, which is fixed to the rotating shaft 33 and is integrally formed with the arc projection 81, and is provided with an arm. When the door 6 that moves toward the fully opened position by the rotation of the means 4 and 5 in the A direction arrives at the position just before the fully opened door, the door 6 is brought into contact with the arc projection 81 to operate completely.

And a limit switch 84 that detects the arrival of the door 6 at a position immediately before the fully closed door by operating in contact with the arc-shaped protrusion 81 when the door arrives. In this example, the limit switch 83 is in contact with the arc projection 81 when the door 6 is moved in the A direction and is disposed, for example, at a position 10 degrees before the fully opened position (position immediately before the fully opened door). It is arranged to operate and to maintain the operation until the door 6 reaches the fully open position. In this example, the limit switch 84 operates by abutting against the arc projection 81 when the door 6 is moved in the B direction and is disposed, for example, at a position 10 degrees before the fully closed position (position immediately before the fully closed door). And it arrange | positions so that the said operation | movement may be maintained until the door 6 reaches a fully closed position. The operation of each of the limit switches 83 and 84 by the contact with the arcuate protrusion 81 is the above-described and later-described operation of the electric motor 7 as an arrival detection signal at the position immediately before the fully opening of the door 6 and the position immediately before the fully closing. It is sent to a control unit (not shown) for control. The flip-up gate 1 is provided with an opening and closing door 6 and an operation switch (not shown) for stopping the door 6.

A chain member 57 in which the portion 53 abuts on the cam edge 54 of the cam plate 51 and is guided to be bent, and the other end portion 55 is rotatably connected to the connector 56 via a pin, and one end 61 is connected to the connector 56. The other end 63 has a coil spring 67 that is hooked in the hole 66 of the connector 65 attached to the column 2. The coil spring 67 urges the cam plate 51 to rotate in the A direction by its contraction elastic force.

  For example, as shown in FIGS. 4 to 7, the resistance force applying means 10 includes a resistance force generating mechanism 21 that generates a resistance force that resists the movement of the door 6 in the flip-up direction, and the resistance force generating mechanism 21 includes the complete door 6. The door 6 that moves in the flip-up direction from the position immediately before the fully opened position and the resistance generating mechanism 21 are connected to generate a resistance force that resists the movement in the flip-up direction from the position immediately before opening to the fully open position. On the other hand, there is provided a connecting mechanism 22 that brings the door 6 positioned closer to the fully closed position than the position immediately before the fully opened door and the resistance generating mechanism 21 into a non-connected state.

  For example, as shown in FIG. 5, the resistance generating mechanism 21 includes a gap forming body 25 made of a housing fixed to the support column 2, and is relatively rotatable with respect to the gap forming body 25 and the gap forming body 25. Are accommodated in a gap 26 formed by the gap forming body 25 and the gap forming body 27, and a gap forming body 27 including a plurality of discs 49 and shafts 50 that form the gap 26 in cooperation with A viscous body 28 that generates a resistance force by the relative rotation of the gap forming body 27 with respect to the gap forming body 25 and a rotation of the gear 29 (described later) in the R1 direction based on the rotation of the arm means 4 in the A direction. The gear 29 and the gap forming body 27 are connected so as to transmit to the gear 27, while the gear 29 and the gap forming body 27 are released by the rotation of the gear 29 in the R2 direction based on the rotation of the arm means 4 in the B direction. And it includes a one-way clutch 24 is interposed between the 27.

  For example, as shown in FIGS. 4 to 7, the coupling mechanism 22 includes a gear 29 attached to the gap forming body 27 so that the gap forming body 27 is rotated by rotation, and the door 6 is in a position immediately before the door is completely opened. A tooth row attached to the arm means 4 so as to be disengaged when the door 6 is positioned on the side of the fully-closed position with respect to the position immediately before the fully-opening door while being engaged with the gear 29 when positioned. Member 30. The tooth row member 30 is in mesh with the gear 29 so as to cause the resistance force generation mechanism 21 to generate a resistance force that resists movement in the flip-up direction from the position immediately before the door 6 is fully opened to the fully opened position. The arm means 4 is arranged to transmit the rotation in the A direction to the gear 29 as a rotational force.

  The gear 29 is fixed to the gap forming body 27 and has a gear member 36 having a plurality of teeth 35 on the periphery, and is displaced in the rotational direction of the gear 29 from the teeth 35 of the gear member 36. A movable gear member 38 which has a plurality of teeth 37 on the periphery and is adjacent to the gear member 36 so as to be movable with respect to the gear member 36 in the rotational direction of the gear 29, and A of the arm means 4. And a biasing means 39 that elastically biases the movable gear member 38 in the rotation direction (R2 direction) opposite to the rotation direction (R1 direction) of the gear 29 based on the rotation of the direction.

  The biasing means 39 is provided on one of the gear member 36 and the movable gear member 38, in this example, the movable gear member 38, and the other of the gear member 36 and the movable gear member 38, in this example, the gear member. The pin 45 projecting toward 36 and the pin 45 elastically toward the rotation direction (R2 direction) opposite to the rotation direction (R1 direction) of the gear 29 based on the rotation of the arm means 4 in the A direction. A coil spring 46 is provided as a biasing member provided on the gear member 36 so as to be biased. The coil spring 46 is accommodated in a groove 47 formed in the gear member 36 so as to extend in the rotational direction.

  A one-way clutch 24 is attached to a portion of the shaft body 50 protruding from the inside of the gap forming body 25. The one-way clutch 24 includes a case body 91 fixed to the gear member 36 in the rotational direction, one end 92 fitted to the case body 91 and the other end being a free end. And a coil member 93 that is wound around the portion of the shaft body 50 and is capable of elastic expansion and contraction. The one-way clutch 24 transmits the rotation in the R1 direction to the gap forming body 27 by the reduced diameter of the coil member 93 that is rotated in the R1 direction together with the case body 91 based on the rotation of the gear member 36 in the R1 direction. The rotation in the R2 direction is not transmitted to the gap forming body 27 due to the diameter expansion of the coil member 93 that rotates in the R2 direction together with the case body 91 based on the rotation of the member 36 in the R2 direction. Note that the one-way clutch 24 includes the coil member 93 in this example, but may include, for example, a so-called one-way bearing.

  The prohibiting means 11 is formed on the support column 2 and is a prohibiting member that abuts on the cam plate 51 so as to prohibit the movement of the door 6 in the flip-up direction when the door 6 is disposed at the fully open position. The stopper 16 is formed on the lower edge of the door 6 and as a prohibiting member that abuts the ground so as to prohibit the movement of the door 6 in the downward direction when the door 6 is disposed at the fully closed position. And a stopper 17.

  Hereinafter, the operation of the flip-up gate 1 of this example will be described. First, the arm means 4 is rotated in the A direction by the rotation of the output rotation shaft of the electric motor 7 based on the operation of the operation unit (not shown), and the door 6 in the fully closed position is moved in the flip-up direction. The movement of the door 6 is assisted by the elastic force in the flip-up direction by the elastic force applying means 9. The elastic force in the spring-up direction of the coil spring 67 biased by the arm means 4 and 5 and the door 6 through the cam plate 51 and the chain member 57 by the rotation of the arm means 4 in the A direction is the force of the coil spring 67. Decrease gradually due to shrinkage. In this example, the arm means 5 is rotated in the A direction when the rotation of the arm means 4 in the A direction is transmitted through the door 6.

  When the door 6 moved in the flip-up direction is disposed at a position immediately before the fully opened door, the circular plate 82 is disposed at a position indicated by a solid line in FIG. Due to the contact, the limit switch 83 is actuated to detect the arrival of the door 6 immediately before the fully opened door, and the arm rotation means 8 reduces the rotation (rpm) of the output rotation shaft of the electric motor 7 based on the detection. Let The arm rotation means 8 is configured to generate an overcurrent to the electric motor 7 generated when the door 6 to be moved in the flip-up direction is disposed at the fully open position and the cam plate 51 comes into contact with the stopper 16 as shown in FIG. The operation of the electric motor 7 is detected and the door 6 is stopped at the fully open position.

  When the door 6 moved in the flip-up direction is disposed at a position immediately before the door is completely opened, the teeth 40 of the dentition member 30 rotated in the A direction together with the rotation of the arm means 4 in the A direction are shown in FIG. As shown in FIG. When the movable gear member 38 is rotated in the R1 direction against the elastic force of the coil spring 46 by the further rotation of the tooth row member 30 in the direction A, the teeth 40 of the tooth row member 30 are shown in FIG. Contacts the teeth 35 of the gear member 36. When the gear member 36 is rotated in the R1 direction by the further rotation in the A direction as shown in FIG. 11 of the tooth row member 30, this rotation is transmitted to the gap forming body 27 via the one-way clutch 24, By this transmission, the gap forming body 27 rotates relative to the gap forming body 25 to generate a viscous shear resistance force on the viscous body 28, and thus the door 6 is fully opened from the position immediately before the door is fully opened. The movement in the flip-up direction toward the position is attenuated by the viscous shear resistance.

  Further, the arm means 4 is rotated in the B direction by the reverse rotation of the output rotation shaft of the electric motor 7 based on the operation of the operation unit (not shown), and the door 6 at the fully opened position is flipped up by the elastic force applying means 9. Move in the downward direction against the elastic force of the direction. The elastic force in the spring-up direction of the coil spring 67 biased by the arm means 4 and 5 and the door 6 via the cam plate 51 and the chain member 57 by the rotation of the arm means 4 in the B direction is the force of the coil spring 67. It gradually increases with elongation. In this example, the arm means 5 is rotated in the B direction when the rotation of the arm means 4 in the B direction is transmitted through the door 6.

  When the door 6 is moved in the downward direction between the fully opened position and the position immediately before the fully opened position, the dentition member 30 is rotated in the B direction by the rotation of the arm means 4 in the B direction. Thus, the gear 29 is rotated in the R2 direction. However, since such rotation is not transmitted to the gap forming body 27 via the one-way clutch 24, a viscous shear resistance force against the downward movement of the door 6 does not occur.

  When the door 6 moved in the downward direction is disposed at a position immediately before the complete closing, the disk 82 is disposed at a position indicated by a two-dot chain line in FIG. The limit switch 84 is actuated by contact to detect the arrival of the door 6 at a position immediately before the fully closed door, and the arm rotation means 8 reduces the reverse rotation (rpm) of the output rotation shaft of the electric motor 7 based on the detection. . The arm rotating means 8 detects an overcurrent to the electric motor 7 generated when the door 6 to be moved in the downward direction is disposed at the fully closed position and the stopper 17 comes into contact with the ground as shown by a solid line in FIG. Thus, the operation of the electric motor 7 is stopped, and thus the door 6 is stopped at the fully closed position.

  According to the flip-up type gate 1 of this example, the support columns 2 and 3, and the arm means 4 and 5 supported by the support columns 2 and 3 at one end 31 so as to be rotatable in the A and B directions in the vertical plane; Attached to the other end 32 of the arm means 4 and 5, the arm means 4 and 5 move in the spring-up direction toward the fully open position by turning in the A direction, while the arm means 4 and 5 B The door 6 moves in the downward direction toward the fully closed position by rotating the direction, and the door 6 is given resistance to resist the movement of the door 6 in the flip-up direction from the position immediately before the fully opened position toward the fully opened position. The resistance force applying means 10 includes a resistance force generating mechanism 21 that generates a resistance force that resists movement of the door 6 in the flip-up direction, and the resistance force generating mechanism 21 has a door 6. In the direction of jumping from the position immediately before full opening to the full opening position. While the door 6 that moves in the spring-up direction from the position just before the fully opened door and the resistance generating mechanism 21 are connected to generate a resistance force that resists movement, the door is moved closer to the fully closed position than the position just before the fully opened door. Since the door 6 and the resistance generating mechanism 21 that are positioned are provided with the connecting mechanism 22 that disconnects the door 6 and the resistance generating mechanism 21, the door 6 and the resistance generating mechanism 21 that are positioned immediately before the fully opened position and between the fully closed positions are provided. And the door 6 can be moved smoothly, and the resistance force against the door 6 that moves in the direction of flip-up from the position immediately before the complete opening to the fully opening position. A resistance force by the generating mechanism 21 can be applied, and a collision of the door 6 with the stopper 16 or the like at the fully open position can be prevented.

  According to the flip-up type gate 1, since it has the elastic force applying means 9 for applying the elastic force in the spring-up direction against the dead weight of the door 6 and the arm means 4 and 5 to the arm means 4 and 5, The door 6 can be moved more smoothly, and the resistance-applying means 10 can prevent a collision of the door 6 with the stopper 16 and the like that has been easily moved in the flip-up direction by the elastic force-applying means 9.

  According to the flip-up type gate 1, the resistance generating mechanism 21 is rotatable relative to the one gap forming body 25 and the gap forming body 25 and cooperates with the gap forming body 25 to form the gap 26. The gap forming body 27 is formed in the gap 26 formed by the other gap forming body 27 and the gap forming body 25 and the gap forming body 27, and the gap forming body 27 is relative to the gap forming body 25. The coupling mechanism 22 includes a gear 29 attached to the gap forming body 27 so that the gap forming body 27 is rotated by the rotation, and the door 6 is completely connected. The arm means 4 and 5 are engaged with the gear 29 when positioned at the position immediately before opening the door, while the engagement is released when the door 6 is positioned closer to the fully closed position than the position immediately before opening the door. , Arm in this example And a dentition member 30 attached to the step 4, and the dentition member 30 has a resistance to resist the movement of the door 6 in the flip-up direction from the position immediately before the fully opened position toward the fully opened position. In order to generate the resistance force generating mechanism 21, since the rotation of the arm means 4 in the direction A is transmitted to the gear 29 as a rotational force in the meshed state with the gear 29, the door 6 bounces. A resistance force depending on the moving speed in the raising direction can be generated, and thus the door 6 can be smoothly moved in the flip-up direction from the position immediately before the fully opened position to the fully opened position, A large resistance force corresponding to an excessive moving speed of the door 6 in the flip-up direction can be generated.

  According to the flip-up type gate 1, the resistance generating mechanism 21 has the gear 29 and the gap forming body so as to transmit the rotation in the R1 direction of the gear 29 based on the rotation of the arm means 4 in the A direction to the gap forming body 27. The one-way clutch interposed between the gear 29 and the gap forming body 27 so as to release the connection by the rotation of the gear 29 in the R2 direction based on the rotation of the arm means 4 in the B direction. 24, the resistance force against the movement of the door 6 in the flip-up direction between the position immediately before the fully opened position and the position of the fully opened door is generated, and the movement of the door 6 in the downward direction is resisted. It is possible to eliminate the generation of resistance, and thus the door 6 can be smoothly moved in the downward direction between the position immediately before the fully opened door and the position of the fully opened door.

  According to the flip-up gate 1, the gear 29 is fixed to the gap forming body 27 and has a gear member 36 having a plurality of teeth 35 on the periphery thereof, and the gear 29 has more gears than the teeth 35 of the gear member 36. A movable gear that has a plurality of teeth 37 that are displaced in the rotational direction at the periphery and is adjacent to the gear member 36 so as to be movable with respect to the gear member 36 in the rotational direction of the gear 29. A biasing force that elastically biases the movable gear member 38 in the rotation direction (R2 direction) opposite to the rotation direction (R1 direction) of the gear 29 based on the rotation of the member 38 and the arm means 4 in the A direction. In the movement of the door 6 in the flip-up direction, the movable gear member 38 is brought into contact with the dentition member 30 prior to the gear member 36, and the movable gear member 38 is in contact with the dentition member 30. After being pushed and moved to By bringing the wheel member 36 into contact with the dentition member 30, the collision sound between the gear 29 and the dentition member 30 can be reduced, and the burden on each of these when the gear 29 and the dentition member 30 are in contact with each other. Can also be reduced.

  In addition, although not shown in the figure, the resistance applying means 10 of the flip-up type gate 1 is not limited to the other resistance generation mechanism that generates a resistance against the movement of the door 6 in the downward direction, and the door to the other resistance generation mechanism. The door 6 that moves in the downward direction from the position immediately before the fully closed door and another resistance force generating mechanism are connected to generate a resistance force that resists the downward movement from the position immediately before the fully closed position 6 toward the fully closed position. On the other hand, the door 6 may be further provided with another connecting mechanism that disconnects the door 6 located on the fully opening position side from the position immediately before the complete closing and the other resistance generating mechanism. The generating mechanism is configured in substantially the same way as the resistance generating mechanism 21, and is rotatable relative to the one gap forming body and cooperates with the one gap forming body. The other gap forming body forming the gap and the other It is accommodated in a gap formed by one gap forming body of the drag generating mechanism and the other gap forming body of the other resistance generating mechanism, and the other gap forming body is relative to the one gap forming body. The other coupling mechanism is configured in substantially the same manner as the coupling mechanism 22 and rotates the other gap forming body of the other resistance generating mechanism by rotation.

And a dentition member attached to the arm means 4 so that the engagement is released when positioned on the door position side. The dentition member of the other coupling mechanism is immediately before the door is completely closed. Down from the position toward the fully closed position In order to cause another resistance generating mechanism to resist the movement in the direction, the rotation of the arm means 4 in the B direction is transmitted to the gear as a rotational force in a meshed state with the gear of the other coupling mechanism. Is arranged. According to such a flip-up gate 1, the door 6 positioned between the position immediately before the complete door closing and the fully open position and the other resistance generating mechanism can be disconnected from each other, and the door 6 can be smoothly moved. It is possible to move the door 6 that moves in the downward direction from the position immediately before the fully closed position toward the fully closed position, and to apply a resistance force by another resistance force generation mechanism, so that the door in the fully closed position 6 can be prevented from colliding with the ground and the like, and a resistance force depending on the moving speed of the door 6 in the lowering direction can be generated. While being able to move smoothly, the big resistance force according to the excessive moving speed of the downward direction of the said door 6 can be produced.

  The other resistance force generation mechanism transmits the rotation in one direction of the gear of the other coupling mechanism based on the rotation of the arm means 4 in the B direction to the other gap forming body of the other resistance force generation mechanism. The gear and the other gap forming body are connected to each other, while the gear and the gear are so disengaged by the rotation of the gear of the other connecting mechanism based on the rotation of the arm means 4 in the other direction. A one-way clutch interposed between the other gap forming body may be provided, and in such a case, the door 6 resists movement in the lowering direction between the position immediately before the complete closing and the position between the complete closing. While generating a resistance force, it is possible to eliminate a resistance force against the movement of the door 6 in the flip-up direction, and thus the door 6 is flipped up between the position immediately before the fully closed position and the fully closed position. It can move smoothly in the direction.
