The length of the second support member 53 can be adjusted by the length adjusting unit 58 according to the length from the end to the connecting member 24.

  And, as the limiting means 51 is pivotally connected to the support column 2 and the door body 3 in this way, the second support member 53 is only in a range in which the second support member 53 is rotatable with respect to the first support member 52. The rotation range of the door 3 in the horizontal direction is limited. In other words, in the closed state, the connecting member main body 14 abuts against the inner edge of the engaging member 62 so that the range of rotation in the closing direction is limited. When the portion comes into contact with the inner edge of the first support member 52, the range of rotation in the opening direction is limited.

  Next, the operation of the first embodiment will be described.

  When the animal apparatus in the barn is brought out of the barn from the doorway and when the animal outside the barn is put into the barn from the doorway, the door holding member 45 is used when the door unit 1 for the barn is changed from the closed state to the open state. The lock by the lock means 47 is released.

  When the lock by the locking means 47 is released, the door body 21 is rotated upward about the horizontal axis X1 by the urging force of the urging means 31.

  Further, the door main body 21 rotating upward is manually rotated to one side in the horizontal direction around the vertical axis Y1 with respect to the support column 2 together with the connection member 4.

  That is, the door 3 is rotated to one side in the horizontal direction around the vertical axis Y1 while being rotated upward about the horizontal axis X1.

  By rotating the door body 3 upward and in the horizontal direction, the restricting means 51 locks the rotation to one side in the horizontal direction. It becomes the opening state arrange | positioned on the upper side of 2 extended lines.

  In this open state, the door body 3 is not disposed on the entrance / exit, and the door body 3 is not disposed on the path along which the animal moving in / out from the entrance / exit moves.

  Thus, after opening the door apparatus 1 for livestock houses, an animal is moved in and out of the livestock house.

  When the entry / exit of the animal is completed, the door 3 is rotated to the other side in the horizontal direction around the vertical axis Y1 and is moved downward around the horizontal axis X1 against the biasing force of the biasing means 31. Rotate.

  When the door body 3 is rotated in the closing direction, when the door main body 21 is disposed on the doorway, the rotation to the other side in the horizontal direction is locked by the restricting means 51 and the lower constituent member 23b. The abutting portion 26 abuts on the locking portion 27 of the connecting member main body 14 and the downward rotation of the door body 3 is locked.

  That is, the rotation of the door body 3 in the closing direction is locked in a closed state in which the door body 21 is disposed so as to block the entrance / exit.

  Next, effects and the like of the first embodiment will be described.

  According to the barn door device 1, the doorway is opened and closed based on the vertical and horizontal rotation of the door body 3, and in the open state, the door body 3 is located above the extension line of the column 2 in front view. Placed in. Therefore, not only the door body 3 is not disposed on the entrance / exit, but also the door body 3 is not disposed on the path through which the animal entering / exiting the entrance / exit can move. Therefore, for example, even when an animal entering / exiting from the entrance / exit is unexpectedly moved to the side, the door 3 is not arranged on the path in which the animal can move, and therefore, an animal entering / exiting the barn is a door. It is difficult to come into contact with the body 3, and the door 3 is less likely to be an obstacle to animal movement.

  By adopting a configuration in which the door body 3 is rotatably attached to the support column 2 via the connecting member 4, a horizontal axis X1 that is a vertical rotation axis and a vertical axis that is a horizontal rotation axis. Since Y1 can be disposed separately, the door body 3 can be rotated more stably in the vertical direction and the horizontal direction.

  Further, since the urging means 31 for urging the rotation and the lock means 47 for maintaining the closed state against the urging force of the urging means 31 are provided, the lock of the lock means 47 in the closed state is provided. Since the door 3 can be rotated in the opening direction simply by releasing the operability, the operability can be improved.

  Further, since the range of rotation of the door body 3 in the horizontal direction can be restricted by the restricting means 51, the door body 3 can be easily placed at an appropriate position in the open state and the closed state, and switching between the open state and the closed state can be performed. It can be performed stably.

  In addition, in the said 1st Embodiment, although it was set as the structure provided with the support | pillar 2 and the connection member 4, it is not limited to such a structure, These support | pillar 2 and the connection member 4 are each selected as needed. However, it is possible to adopt a configuration in which none is provided.

  The door body 3 is configured to include the biasing means 31 and the locking means 47, but is not limited to such a configuration, and may be configured such that the biasing means 31 and the locking means 47 are not provided.

  Moreover, in the case of the configuration in which the biasing means 31 is provided, the biasing means 31 is not limited to the configuration in which only the vertical rotation of the door body 3 is biased. Any configuration may be used as long as it is biased to rotate in at least one of the horizontal direction and the horizontal direction.

  Further, the door body 3 is not limited to the urging force of the urging means 31 and the configuration of manually rotating the door body 3, and may be configured to operate the rotation electrically using a driving device such as a motor.

  In addition, the configuration in which the urging means 31 is provided is not limited to the configuration in which the door body 3 is rotated upward by the urging force of the urging means 31, and the urging means 31 is energized in the closed state. By adjusting the force and the weight of the door body 3 to be balanced, when the door body 3 is opened, the balanced state is released simply by applying a force to manually lift the door body 21 upward slightly. In this case, it may be configured to rotate.

  In addition, the restricting means 51 for restricting the range of rotation of the door body 3 in the horizontal direction is provided. However, the structure is not limited to such a structure, and the restricting means 51 is not provided. Good.

  Further, in the case of a configuration in which the limiting means 51 is provided, the configuration of the limiting means 51 can be changed as appropriate.

  For example, instead of the limiting means 51, a configuration in which the limiting means 61 is provided as in the second embodiment shown in FIG.

  The restricting means 61 has a cylindrical engaging member 62 fixed to the rod member 12 of the column 2 and a protruding engaged member 63 fixed to the connecting member 4.

  The engaging member 62 is provided so as to cover a part of the rod member 12 slightly below the portion of the rod member 12 where the rotation attachment portion 15 is attached.

  Further, the engaging member 62 includes a cylindrical portion 64 fixed to the rod member 12, and a groove portion 65 provided in a partial range in the circumferential direction at the upper end edge of the cylindrical portion 64. .

  The groove portion 65 is formed so as to cut out a part of the tubular portion 64 from the upper end edge portion of the tubular portion 64 downward.

  Further, the groove portion 65 can be engaged with the engaged member 63, and the engaged member 63 in an engaged state can slide in the horizontal direction along the groove portion 65.

  The groove 65 has a first locking portion 66 and a second locking portion 67 that lock the sliding of the engaged member 63 in the engaged state.

  The first locking portion 66 and the second locking portion 67 are constituted by circumferential ends of the groove portion 65.

  Further, a boundary portion formed in a convex arc shape above the first locking portion 66 and the second locking portion 67 between the first locking portion 66 and the second locking portion 67. 68 is formed continuously with the first locking portion 66 and the second locking portion 67.

  The engaged member 63 has a columnar protrusion 69 provided so as to protrude slightly from below the rotation attachment portion 15 on one side surface of the connection member main body 14.

  The protrusion 69 can be engaged with the engagement member 62 so that the outer peripheral surface is in contact with the groove 65. Further, the protrusion 69 is slidable along the groove 65 as the connecting member 4 is rotated with respect to the support column 2 in the horizontal direction in a state of being engaged with the engaging member 62. In other words, the engaged member 63 can be rotated with respect to the engaging member 62 as the door body 3 rotates in the horizontal direction in a state where the engaged member 63 is engaged with the engaging member 62.

  Further, the protrusion 69 has a horizontal rotation range limited by the first locking portion 66 and the second locking portion 67. That is, in a state where the doorway is closed by the door body 3, the projecting portion 69 contacts the first locking portion 66, and the rotation of the engaged member 63 in the closing direction in the horizontal direction is locked. The Further, in a state where the doorway is opened, the protrusion 69 abuts on the second locking portion 67 and the rotation of the engaged member 63 in the horizontal direction is locked.

  Thus, in the configuration in which the rotation range in the horizontal direction of the door body 3 is limited by the engagement state of the engagement member 62 and the engaged member 63, the rotation range can be reliably limited with a simple configuration.
