JP 2006-29062 A

  However, in Patent Document 1, there is a case where the safety door body is stretched at a portion where the safety door body is caught, and thus it is difficult to smoothly swing to the winding opening posture. Has been.

  The present invention has been made to meet the above-described demand, and an object of the present invention is to provide a highly safe revolving door device that can reliably prevent entrainment.

  In order to solve the above-mentioned problems, the present invention provides a rotating door portion of a rotating partition member that can rotate in one direction along the inner surface of an outer frame in a cylindrical outer frame having an entrance and exit at opposing positions. In the revolving door device, a safety door body that is located inward of the revolving door portion and protrudes in the revolving direction from the front end portion of the revolving door portion is disposed on the revolving door front end side of the revolving partition portion. The safety door body is supported by the rotating partition body via a support mechanism, and moves to a normal position approaching the rotating door section and a retreat position moving substantially inwardly away from the rotating door section. A revolving door device characterized by being capable of being provided is provided.

  According to a second aspect of the present invention, the support mechanism is a link mechanism that forms a parallelogram by a pair of links having one end connected to the rotating partition body and the other end connected to the safety door body. It is preferable that the body is temporarily held so as not to move from the normal position at all times.

  According to a third aspect of the present invention, the support mechanism is attached to the rotating partition, and is attached to a pair of rails extending obliquely in a direction opposite to the rotation direction of the rotating partition, and a safety door, and is guided by the rails. It is preferable that the safety door body is temporarily held so as not to move from the normal position.

  According to a fourth aspect of the present invention, the rotating partition is continuously rotated by a motor, and a control means is provided for urgently stopping the rotation of the motor when it is detected that the safety door body has moved from the normal position. It is preferable.

  As in claim 5, the dimension in which the safety door body protrudes in the rotational direction from the distal end portion of the rotary door part of the rotary partition body and the dimension in which the safety door body moves substantially inward are the rotary partition body. It is preferable that the dimension is set such that a clearance for preventing entrainment is ensured between the outer frame stand and the safety door body in a state where the emergency stop is completely stopped.

  According to the present invention, on the front end side in the rotation direction of the rotary door portion of the rotary partition, the normal position approaching the rotary door portion and the retracted position away from the rotary door portion and moving substantially inwardly are moved. Since a possible safety door body is provided, when a passerby is about to be caught between the outer frame stand and the safety door body, the safety door body moves substantially parallel to the revolving door and moves to the retracted position. Because it always moves, the gap between the rotating door part of the rotating partition and the outer frame and the safety door body widens widely, and the part that is likely to be caught from this widened gap can be quickly extracted, so the entrainment is ensured Can be prevented.

  Further, the safety door body is supported by the rotating partition body via a support mechanism, and can move to a normal position approaching the rotating door part and a retracted position away from the rotating door part and substantially parallel to the inside. Since it did in this way, a safety door body comes to be able to move smoothly so that the clearance gap between the rotation door part and outer frame of a rotation partition body may spread widely.

  According to the second aspect, since the safety door body is supported by the rotary partition body via the support mechanism which is a parallelogram link, the safety door body can move more smoothly. In addition, the safety door body is temporarily held in the normal position at all times, and in the event of an emergency, the temporary holding can be released by simply pulling the safety door body with a slightly strong force, thereby improving safety and release operability. It becomes like this.

  According to the third aspect, since the safety door body is supported by the rotary partition body via the support mechanism constituted by the rail and the door pulley, the safety door body can move more smoothly. In addition, the safety door body is temporarily held in the normal position at all times, and in the event of an emergency, the temporary holding can be released simply by pulling the safety door body with a slightly strong force. To improve. Furthermore, since the safety door body moves in the direction opposite to the rotation direction of the rotary partition body by the rail, the impact when the safety door body collides with the part that is about to be caught is reduced.

  According to the fourth aspect, when the safety door body moves from the normal position, the rotation of the motor is urgently stopped, so that the rotation partition body is urgently stopped and the rotation partition body itself is in a free state. Will become more improved.

  According to the fifth aspect, if the clearance for preventing the entrainment is set to a dimension such as the head of the infant, the safety for the infant or the like is further improved.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  1 and 2 show the rotary door device according to the first embodiment. FIG. 1 is a plan sectional view, FIG. 2 (a) is a side sectional view of the AA portion in FIG. 1, and FIG. It is a principal part top view of Fig.2 (a).

  The revolving door device includes a cylindrical outer frame 1 having a pair of entrances 1a at opposing positions, and a revolving door portion 2c (described later) around the inner surface of the outer frame 1 in one direction. a is provided with a rotatable partition 2. The rotating partition 2 is continuously rotated at a constant speed around a direction a by a motor 4 (see FIG. 5). In addition, the rotation partition 2 may be rotated around a direction a by a passer's hand pushing it.

  The rotary partition 2 is attached to the plate-like partition 2a passing through the rotation center O, the V-shaped attachment 2b attached to both ends of the partition 2a, and the outer end of the attachment 2b. An arcuate rotating door portion 2c extending along the inner surface of the outer frame 1, and the rotating door portion 2c is provided on a side wall 1b of the entrance / exit 1a of the outer frame 1 located on the rear side of the rotating partition 2 in the rotation direction. When the front end portion 2d matches, the entrance / exit 1a is fully opened, and the front end portion 2d of the rotary door portion 2c matches the vertical 1c of the entrance / exit 1a of the outer frame 1 located on the front side in the rotation direction of the rotary partition 2 When this is done, the doorway 1a is fully closed.

  A safety door body 3 is located on the distal end side in the rotational direction a of the rotating door portion 2c of the rotating partition 2 and is located inward of the rotating door portion 2c and protrudes in the rotational direction a from the distal end portion of the rotating door portion 2c. Is arranged. The safety door body 3 is supported on the upper part of the rotary door portion 2 c of the rotary partition 2 via a support mechanism 5.

  As shown in detail in FIGS. 2 (a) and 2 (b), the support mechanism 5 has one end connected to the front and rear positions in the rotational direction a on the upper part of the rotary door 2 c of the rotary partition 2, and the other end It comprises a link mechanism that forms a parallelogram by a pair of links 8 respectively connected to the upper end of the safety door body 3.

  And by this support mechanism 5, the safety door body 3 moves away from the normal position (refer to a broken line) N approaching the revolving door portion 2c and the revolving door portion 2c, and substantially translates inward (see arrow b). It can move to the retracted position (see solid line) S.

  For example, the safety door body 3 is temporarily held at the normal position N by an urging force of a spring mechanism (not shown) so that the safety door body 3 does not always move from the normal position N. Then, the temporary holding can be canceled and the retreat position S can be moved by simply performing an operation such as pulling with a slightly strong force. Further, the safety door body 3 is temporarily held by fitting a click mechanism (not shown). In an emergency, the safety door body 3 can be temporarily moved by pulling it with a slightly strong force so that the safety door body 3 can be pulled out of the fitting. The holding can be released. In the case of the spring mechanism, when the operation such as pulling the safety door body 3 is stopped, the safety door body 3 automatically returns to the normal position N by the biasing force, and in the case of the click mechanism, the safety door body 3 When an operation such as pressing is performed, the safety door body 3 can be manually returned to the normal position N.

  Further, the dimension P that the safety door body 3 projects in the rotational direction from the tip of the rotary door portion 2c of the rotary partition body 2 and the dimension Q that the safety door body 3 moves substantially inwardly are the rotary partition body. 2 is set to a dimension (see a white circle on the broken line) that secures a clearance T for preventing entrainment between the vertical frame 1c of the outer frame 1 and the safety door body 3 in a state where the emergency stop is completely stopped.

  In the case of the revolving door device of the first embodiment, the normal position N approaching the revolving door portion 2c and the revolving door portion 2c on the front end side in the rotating direction of the revolving door portion 2c of the revolving partition 2 are separated from the revolving door portion 2c. Since the safety door body 3 that is movable to the retreat position S that moves substantially in parallel to the direction is provided, when the passerby is about to be caught between the vertical stand 1c of the outer frame 1 and the safety door body 3, the safety door Since the body 3 moves substantially parallel to the revolving door portion 2c and always moves to the retracted position S, the clearance T between the revolving door portion 2c and the outer frame 1 of the revolving partition 2 and the safety door body 3 is large. Since it spreads and the part which was likely to be caught from this widened gap T can be quickly extracted, it is possible to reliably prevent the entrainment.

  In addition, the safety door body 3 is supported by the rotary partition 2 via the support mechanism 5 and moves substantially inward away from the normal position N approaching the rotary door part 2c and away from the rotary door part 2c. Since it can move to the retreat position S, the safety door body 3 can move smoothly so that the gap T between the rotary door portion 2c of the rotary partition 2 and the outer frame 1 widens greatly.

  Furthermore, since the safety door body 3 is supported by the rotary partition body 2 via the support mechanism 5 which is a parallelogram link, the safety door body 3 can move more smoothly. In addition, the safety door 3 can be temporarily held at the normal position N at all times, and the temporary holding can be released simply by pulling the safety door 3 with a slightly strong force in an emergency. Operability is improved.

  Furthermore, if the clearance T for preventing entrainment is set to a dimension such as the head of an infant, for example, the safety for the infant or the like is further improved.

  The support mechanism 5 is different from the first embodiment. That is, as shown in detail in FIGS. 4A and 4B, the support mechanism 5 has a pair of rails 11 attached to the front and rear positions in the rotational direction a on the upper part of the rotary door portion 2c of the rotary partition 2. The rail 11 is set to extend obliquely in the direction opposite to the rotation direction a of the rotary partition 2.

  In addition, a pair of door pulleys 12 that are respectively guided by the rails 11 are attached to the safety door body 3. Reference numeral 15 denotes a stopper for the door pulley 12.

  And by this support mechanism 5, the safety door body 3 moves away from the normal position (refer to a broken line) N approaching the revolving door portion 2c and the revolving door portion 2c, and substantially translates inward (see arrow b). It can move to the retracted position (see solid line) S. Other configurations are the same as those of the first embodiment.

  In the case of the revolving door device of the first embodiment, the safety door body 3 is supported by the rotating partition body 2 via the support mechanism 5 constituted by the rails 11 and the door pulleys 12. You can move more smoothly. In addition, the safety door 3 can be temporarily held at the normal position N at all times, and in the event of an emergency, the temporary holding can be released simply by pulling the safety door 3 with a slightly strong force. Will be improved.

  Furthermore, since the safety door body 3 is moved by the rail 11 in the direction opposite to the rotation direction a of the rotary partition body 2, the impact when the safety door body 3 collides with the part that is about to be caught is reduced. Become.

  In the first and second embodiments, as shown in FIG. 5, when the rotary partition 2 is continuously rotated by the motor 4, the limit switch or the like 14 indicates that the safety door body 3 has moved from the normal position N. If the control circuit 13 for urgently stopping the rotation of the motor 4 is provided, the rotating partition body 2 is urgently stopped and the rotating partition body 2 itself becomes free, so that the safety is further improved. become.
