The entrance / exit frame 2 has a pair of vertical columns 3 located on both sides of the entrance / exit 1 and an upper beam 4 located above the entrance / exit 1 and connected between upper ends of the vertical columns 3. .

  A hanger case (not shown) fixed to the car is disposed at the upper part of the doorway 1. The hanger case supports a door rail (not shown) arranged along the frontage direction (width direction) of the doorway 1. A pair of sliding doors (cage doors) 5 are hung on the door rail. As shown in FIGS. 2 and 3, each sliding door 5 is arranged so as to be shifted from the entrance / exit frame 2 in the depth direction of the entrance / exit 1, and is arranged on the opposite side (hoistway side) from the inside of the cage as seen from the entrance / exit frame 2. .

  The respective sliding doors 5 are movable in opposite directions along the entrance direction of the doorway 1 while being guided by the door rail by a driving force of a door driving device (not shown) provided in the car. Moreover, each sliding door 5 is located between the door closing position (FIG. 2) which closes the doorway 1 and the door opening position (FIG. 3) which is located in the entrance direction 1 outer side of the doorway 1 rather than the door closing position. It can be moved. That is, each sliding door 5 opens and closes the doorway 1 by receiving the driving force of the door driving device and moving in the opposite directions along the opening direction of the doorway 1.

  Each sliding door 5 includes a door body 6 including a door panel, and a first door leg 7 and a second door leg 8 (a pair of door legs 7 and 8) provided at the lower end of the door body 6. Have. As shown in FIGS. 2 and 3, each sliding door 5 is moved in the entrance direction of the entrance 1 while securing a gap between the door body 6 and the vertical column 3 in the depth direction of the entrance 1.

  A sill (cage sill) 9 fixed to the floor of the car is disposed below the doorway 1. On the upper surface of the sill 9, a sill groove 10 opened upward is provided along the moving direction of each sliding door 5 (that is, the frontage direction of the doorway 1). The elevator entrance / exit device has each sliding door 5 and threshold 9.

  The first and second door legs 7 and 8 each have a sliding member 11 inserted into the sill groove 10. In this example, the shape of the sliding member 11 is a substantially rectangular parallelepiped arranged along the length direction of the sill groove 10 (the moving direction of the sliding door 5). Each sliding door 5 is moved between the door closing position and the door opening position in a state where the legs 7 and 8 of the first and second doors are inserted into the sill groove 10.

  As shown in FIGS. 2 and 3, the threshold groove 10 includes a guide groove 10 a that guides the legs 7 and 8 of the first and second doors in the moving direction of the sliding door 5, and a guide groove 10 a in the moving direction of the sliding door 5. And a first widened groove portion 10c and a second widened groove portion 10c each having a larger width dimension than the guide groove portion 10a. The first widening groove 10b and the second widening groove 10c are provided in pairs in the sill groove 10 corresponding to the number of legs 7 and 8 of the first and second doors.

  The width dimension of the guide groove 10a is the same dimension at any position in the moving direction of the sliding door 5. Moreover, the width dimension of the guide groove part 10a is made into the predetermined dimension which controls the displacement of the sliding member 11 to the width direction of the guide groove part 10a.

  The first widening groove portion 10b and the second widening groove portion 10c are respectively located at predetermined positions on the door opening side with respect to the positions of the legs 7 and 8 of the first and second doors when the sliding door 5 is in the door closing position. Is provided. In this example, the first widening groove portion 10 b is provided in the vicinity of the vertical column 3. The 2nd widening groove part 10c is provided in the position away from the 1st widening groove part 10b to the door opening side. The distance between the first widening groove 10b and the second widening groove 10c is equal to the distance between the first door leg 7 and the second door leg 8 provided on the common sliding door 5. I'm doing it. The first widened groove portion 10 b is provided at a symmetrical position with respect to the center line of the doorway 1, and the second widened groove portion 10 c is also provided at a symmetrical position with respect to the central line of the doorway 1.

  The 1st widening groove part 10b and the 2nd widening groove part 10c are formed so that it may spread on the opposite side to the entrance / exit frame 2 rather than the guide groove part 10a. That is, of the pair of inner surfaces of the sill groove 10, one of the inner surfaces closer to the entrance / exit frame 2 is the sliding door 5 in any of the guide groove portion 10a, the first widened groove portion 10b, and the second widened groove portion 10c. Are formed on a common plane along the moving direction. The other inner surface of the sill groove 10 on the side far from the entrance / exit frame 2 is formed at a position away from one inner surface by a predetermined dimension in the guide groove portion 10a, and one in the first and second widened groove portions 10b and 10c. It is formed at a position separated from the inner surface by a dimension larger than the width dimension of the guide groove 10a.

  The width dimension of the 2nd widening groove part 10c is smaller than the width dimension of the 1st widening groove part 10b. Further, the other inner side surface (the inner side surface far from the entrance / exit frame 2) located at both ends in the length direction of the first and second widening groove portions 10b, 10c is provided with the first and second widening groove portions 10b, Inclined surfaces 12 that continuously reduce the width dimension of 10c toward the guide groove 10a are provided.

  When the sliding door 5 is in the door closed position, as shown in FIG. 2, each of the legs 7 and 8 of the first and second doors is disposed in the guide groove portion 10a. When the sliding door 5 reaches the door open position, as shown in FIG. 3, the leg 7 of the first door enters the first widening groove portion 10b and the leg 8 of the second door is the second widening groove portion. Enter 10c. When the leg 7 of the first door enters the first widening groove 10b and the leg 8 of the second door enters the second widening groove 10c, the space between the vertical column 3 and the door body 6 Displacement of the first and second door legs 7 and 8 in the direction in which the gap is widened (that is, the direction in which the door body 6 is separated from the vertical column 3) is allowed.

  Here, when the sliding door 5 is moving in the door opening direction, as shown in FIG. 3, a foreign object (for example, a passenger's baggage) 21 is drawn between the vertical column 3 and the door body 6, so As a result, the foreign material 21 may be damaged.

  FIG. 4 is an enlarged view showing a state in which a foreign substance 21 is sandwiched between the vertical column 3 and the door body 6 of FIG. FIG. 5 is a cross-sectional view taken along the line VV in FIG. When the foreign object 21 is sandwiched between the vertical column 3 and the door body 6 when the sliding door 5 is in the door open position, the door body 6 is pushed by the foreign object 21 and the legs of the first and second doors 7 and 8 are displaced in a direction away from the vertical column 3, and the gap between the vertical column 3 and the door body 6 is widened. Thereby, the impact and compression which the foreign material 21 receives are reduced greatly. At this time, since the width dimension of the second widening groove portion 10c is smaller than the width dimension of the first widening groove portion 10b, the leg 7 of the first door is connected to the second door as shown in FIG. The sliding door 5 is displaced more than the leg 8 and is inclined with respect to the length direction of the sill groove 10 (moving direction of the sliding door 5). Thereby, the foreign material 21 is easily detached from between the vertical column 3 and the door body 6.

  In this example, the normal gap dimension d (FIG. 5) between the vertical column 3 and the door body 6 is about 3 mm to 6 mm. Moreover, in this example, the width dimension of the 1st widening groove part 10b is 8 mm or more larger than the width dimension of the guide groove part 10a. Thereby, when the sliding door 5 is in the door open position, the sliding door 5 with respect to the vertical column 3 is until the gap dimension d between the vertical column 3 and the door main body 6 becomes about 11 mm or more at the height position of 500 mm on the car floor. Displacement of is acceptable.

  FIG. 6 is a cross-sectional view showing a state when the leg 8 of the second door of FIG. 2 enters the first widening groove 10b. When the sliding door 5 opens and closes the doorway 1, the leg 8 of the second door may pass through the first widening groove 10b. At this time, since the leg 8 of the second door is disengaged from the guide groove portion 10a, there is no restriction on the width direction of the leg 8 of the second door. However, since the leg 7 of the first door is guided by the guide groove portion 10 a, the first door leg 7 is prevented from being inclined with respect to the moving direction of the sliding door 5. Thereby, even if the leg 8 of the 2nd door passes the 1st widening groove part 10b in the middle of opening and closing of the entrance / exit 1, it is suppressed that the sliding door 5 shakes to right and left.

  Next, the operation will be described. When the doorway 1 is opened and closed, the sliding doors 5 are moved while the legs 7 of the first and second doors are guided by the guide grooves 10a, and the swinging of the sliding doors 5 to the left and right is suppressed.

  When the sliding door 5 reaches the door open position, the legs 7 and 8 of the first and second doors enter the first and second widening grooves 10b and 10c, respectively, and the first in the direction away from the vertical column 3 And displacement of the second door legs 7, 8 is possible. At this time, when the foreign material 21 is sandwiched in the gap between the vertical column 3 and the door main body 6, the gap between the vertical column 3 and the door main body 6 is as shown in FIGS. It spreads and the foreign material 21 becomes easy to remove from the gap between the vertical column 3 and the door body 6.

  In such an elevator doorway apparatus, the first and second widened groove portions 10b and 10c have a larger width dimension than the guide groove portion 10a, and the gap between the vertical column 3 and the door main body 6 is widened. Since the displacement of the legs 7 and 8 of the first and second doors is allowed, the vertical column 3 can be obtained only by forming a part of the sill groove 10 as the first and second widening groove portions 10b and 10c. And the door body 6 can be easily widened. Thereby, when the foreign material 21 is pinched in the gap between the vertical column 3 and the door main body 6, it is possible to reduce the impact and pressure on the foreign material 21, and from the gap between the vertical column 3 and the door main body 6. The foreign matter 21 can be easily removed. Therefore, the foreign substance 21 can be prevented from being drawn into the gap between the vertical column 3 and the sliding door 5 with a simple configuration.

  When the first and second door legs 7 and 8 are provided at the lower end of the door body 6 and the sliding door 5 is in the door open position, the first door leg 7 is the first widening groove 10b. Since the second door leg 8 enters the second widening groove 10c, not only can the foreign material 21 be easily removed from the gap between the vertical column 3 and the door body 6, but also the opening / closing operation. Sometimes, the sliding door 5 can be guided more stably toward the frontage of the doorway 1.

  Moreover, since the width dimension of the 2nd widening groove part 10c located in the door opening side rather than the 1st widening groove part 10b is smaller than the width dimension of the 1st widening groove part 10b, the vertical column 3 and the door main body The sliding door 5 can be inclined with respect to the length direction of the sill groove 10 when the gap between the sill groove 10 and the sill groove 10 increases. Thereby, the clearance dimension between the vertical pillar 3 and the door main body 6 can be made to spread continuously toward the entrance direction inner side of the entrance / exit 1, and from the gap between the vertical pillar 3 and the door main body 6. The foreign material 21 can be further easily removed.

  In the above example, the width of the second widened groove 10c is smaller than the width of the first widened groove 10b, but the width of the second widened groove 10c is changed to the width of the first widened groove 10b. If the expansion of the gap between the vertical column 3 and the door body 6 is ensured, the width of the second widening groove 10c is the first widening groove 10b. It may be larger than the width dimension.

  In the above example, the number of door legs provided on the common sliding door 5 is two of the first and second door legs 7, 8. The number of legs may be one, or may be three or more. In this case, the number and position of the widening groove are set in accordance with the number and position of the door legs.

Embodiment 2. FIG.
FIG. 7 is a horizontal sectional view showing an elevator doorway apparatus according to Embodiment 2 of the present invention. FIG. 8 is a horizontal cross-sectional view showing a state in which the foreign matter 21 is sandwiched in the gap between the sliding door 5 and the vertical column 3 in FIG. In the figure, the sill groove 10 includes a guide groove portion 10a similar to that of the first embodiment, and a pair of widened groove portions 10d that are continuous with the guide groove portion 10a and have a width dimension larger than that of the guide groove portion 10a.

  Each widening groove portion 10d is provided at a predetermined position on the door opening side with respect to any position of the legs 7 and 8 of the first and second doors when the sliding door 5 is in the door closing position. The widening groove 10 d is provided at a symmetrical position with respect to the center line of the entrance 1.

  The length dimension of the widened groove part 10d is longer than the length dimension of the first widened groove part 10b in the first embodiment. That is, the length dimension of the widening groove portion 10d is set such that the leg 8 of the second door can move within the widening groove portion 10d by a predetermined distance in the moving direction of the sliding door 5. The length of the widening groove 10d is such that the legs 7 and 8 of the first and second doors provided in the common sliding door 5 can be accommodated together. The other configuration of the widened groove portion 10d is the same as the configuration of the first widened groove portion 10b in the first embodiment.

  The leg 7 of the first door has a sliding member 31 inserted into the threshold groove 10. The shape of the outer peripheral surface of the sliding member 31 in the leg 7 of the first door is the shape of the outer peripheral surface of a cylinder having an axis along the vertical direction. Therefore, the sliding door 5 is rotatable about the axis line along the vertical direction of the first door leg 7 in a state where the first door leg 7 is inserted into the guide groove 10a. . Other configurations are the same as those in the first embodiment.

  Next, the operation will be described. When each sliding door 5 is moved in the door opening direction from the door closing position, first, the leg 8 of the second door enters the widening groove portion 10d. Thereafter, the leg 7 of the first door enters the widening groove 10d, and the sliding door 5 reaches the door open position. When the sliding door 5 is in the door open position, the legs 7 and 8 of the first and second doors both enter the widening groove portion 10d, and the gap between the vertical column 3 and the door body 6 is widened. The first and second door legs 7 and 8 can be displaced.

  In addition, as shown in FIG. 8, in the state where only the second door leg 8 of the first and second door legs 7 and 8 enters the widening groove portion 10d, the vertical column 3 and the door main body are provided. When the foreign object 21 is sandwiched between the gaps 6, the sliding door 5 is rotated around the leg 7 of the first door, and the leg 8 of the second door is displaced in a direction away from the vertical column 3. . Thereby, the clearance gap between the vertical pillar 3 and the door main body 6 spreads, and the foreign material 21 becomes easy to remove | deviate from the clearance gap between the vertical pillar 3 and the door main body 6. FIG.

  In such an elevator doorway apparatus, the shape of the outer peripheral surface of the sliding member 31 in the first door leg 7 disposed on the door closing side of the first and second door legs 7 and 8 is: Since it is made into the shape of the outer peripheral surface of the cylinder with the axis line along an up-down direction, even if it is in the state where the leg 7 of the 1st door exists in the guide groove part 10a, it is a sliding door centering on the leg 7 of the 1st door 5 can be made rotatable. As a result, if the leg 8 of the second door has entered the widening groove 10d, the foreign object 21 can be separated from the vertical column 3 and the sliding door 5 even if the leg 7 of the first door has not entered the widening groove 10d. The gap between the vertical column 3 and the sliding door 5 can be widened when sandwiched between the gaps. Accordingly, it is possible to further reliably suppress the foreign material 21 from being drawn into the gap between the vertical column 3 and the sliding door 5.

  Further, the length dimension of the widening groove portion 10d is such that the leg 8 of the second door is movable within the widening groove portion 10d by a predetermined distance in the moving direction of the sliding door 5. It is possible to avoid the foreign substance 21 from being drawn into the gap between them in a wider range.

  In the above example, of the first and second door legs 7 and 8, only the shape of the outer peripheral surface of the sliding member 31 in the first door leg 7 is the shape of the outer peripheral surface of the cylinder.
