[Prior Art]

 In advanced and complicated urban spaces such as airports, business parks, shopping centers, and resort facilities, there is a demand for low-noise, low-vibration and safe short-distance transportation. In order to meet this demand, the applicant has proposed a horizontal elevator as shown in FIGS. 4 to 6 as a system in which the elevator lifting principle is applied in the horizontal direction (Japanese Patent Publication No. Sho 63-49669, Japan Society of Mechanical Engineers). (See No.910-3) Proceedings of Technical Lecture Meeting).

In FIG. 4, a vehicle 101 is not provided with wheels for traveling on a track 104, but is provided with an air levitation device 102 for levitating from the track 104. In order to run the vehicle 101, a closed-loop steel rope 103 is arranged along a track 104 laid as shown in FIG. 5, and the steel rope 103 is attached to the vehicle 101. When the steel rope 103 is towed by the hoist 105, the levitating vehicle 101 travels horizontally between the halls 106 and 107.

By the way, when there are a large number of passengers at the halls 106 and 107, some of the passengers are pushed to the track 104 side. If this happens, the passengers may come into contact with the vehicle 101 and cause an accident, which is dangerous. In order to prevent such a contact accident from occurring, it is necessary to provide hall doors 108 and 109 on the track side of the hall 106 as shown in FIG. The hall doors 108 and 109 are opened by the electric motor when the vehicle 101 arrives, and closed when the vehicle 101 starts.

[0005]

However, when the hall doors 108 and 109 are provided on the track side of the hall 106 in this manner, if the electric motors that open and close the hall doors 108 and 109 fail and do not operate, the hall doors. 108 and 109 cannot be opened or closed. In particular, if the landing doors 108 and 109 stop when they are opened, the above-mentioned failure may occur.

On the other hand, the passengers in the hall 106 need to visually recognize the arriving vehicle 101. Therefore, in order to improve the visibility on the track side, transparent glass must be used for the landing doors 108 and 109. Therefore, if the hall doors 108 and 109 are provided with a mechanism for solving the above-mentioned problem, that is, a mechanism for automatically closing the hall doors 108 and 109, this mechanism does not prevent the line of sight from being obstructed. There must be.

It is an object of the present invention to provide an automatic closing mechanism for a landing door that automatically closes the landing door and does not hinder the visibility on the track side.

[0008]

[Means for Solving the Problems]

 In order to achieve such an object, according to the present invention, an opening / closing arm is provided above a landing door provided at a landing of a horizontal elevator, and an opening / closing arm connected to the landing door is provided. The opening / closing arm is provided with a supporting arm extending toward the opening direction of the landing door, and a closing weight attached to the supporting arm.

[0009]

[Action]

 If the driving means fails and does not drive when the hall door is opened, the hall door may remain open. In this case, the opening / closing arm receives a biasing force by the closing weight attached via the support arm, and automatically closes the hall door.

On the other hand, since the landing door is opened and closed by the opening and closing arm disposed above this, the closing weight attached to this opening and closing arm via the support arm is located above the landing door. To position.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. 1 to 3 are views showing an embodiment of an automatic closing mechanism for a horizontal elevator hall door according to the present invention.

In FIG. 1, a pillar (not shown) is erected on the track side of the landing 1, and a support frame 2 and a guide rail 3 are horizontally installed above the pillar. A pair of landing doors 6 and 7 made of glass are slidably supported on the guide rail 3 via rollers 4 and 5 which are in sliding contact with the upper and lower sides. As shown in FIG. 2, a motor 9 is provided in the substantial center of the support frame 2 via a support base 8, and a pulley 10 is attached to the motor 9 via a reduction mechanism. Links 11 and 12 are attached. The links 11 and 12 are connected to a pair of links 13 and 14 (opening / closing arms) rotatably provided on the support frame 2. The ends of the links 11 and 13 have adjusting members 11a and 13a. If bolts are fastened to the elongated holes formed in the adjusting members 11a and 13a, respectively, the respective lengths of the links 11 and 13 can be reduced. Can be fine-tuned. The links 12 and 14 also have similar adjusting members 12a and 14a. The pair of landing doors 6 and 7 are attached to the tips of the links 13 and 14 via auxiliary links 15 and 16.

When the motor 9 is driven, the hall doors 6 and 7 are moved and opened in the directions of arrows A and B via the links 11 and 13 and the links 12 and 14, respectively. Further, the hall doors 6 and 7 are closed by moving in the directions of arrows C and D, respectively. The arrow A direction side 13b of the link 13 is the hall door opening direction side, and the arrow C direction side 13c is the hall door closing direction side. The arrow B direction side 14b of the link 14 is the hall door opening direction side, and the arrow D direction side 14c is the hall door closing direction side.

Supporting arms 17 and 18 are extended to the hall opening direction sides 13b and 14b, which are rotation centers of the links 13 and 14, and closing weights 19 and 20 are attached thereto. That is, mounting panels 21 and 22 are welded to the base ends of the support arms 17 and 18, and the mounting panels 21 and 22 are fixed to the links 13 and 14 by bolts. At the front end side of the support arms 17 and 18 in the opening direction of the landing door, a cold rolled steel plate (SPC) having a substantially square shape and notched corners is used as the closing weights 19 and 20 by two bolts 23 and 24. It is detachably attached. As shown in FIG. 3, the closing weights 19 and 20 are made up of a plurality of (two in this embodiment) cold-rolled steel plates, and the closing weights are changed by changing the number of the cold-rolled steel plates. The weight of 19, 20 can be adjusted.

When the vehicle 25 arrives at the landing 1 and the door of the vehicle 25 opens, at the same time, the motor 9 rotates in the forward direction to rotate the pulley 10, and the pair of landing doors are connected via the links 11 and 13 and the links 12 and 14. Open 6 and 7. When the door of the vehicle 25 is closed, the motor 9 is also reversed at the same time, and this time the hall doors 6 and 7 are closed.

When the pair of hall doors 6 and 7 are opened by the rotation of the motor 9 and the motor 9 fails and does not rotate, the hall doors 6 and 7 remain open. Then, the links 13 and 14 receive a biasing force in the directions of arrows C and D in FIG. 1 by the closing weights 19 and 20 attached via the support arms 17 and 18, so that the pair of landing doors 6 and 7 are closed. Close automatically. When the hall doors 6 and 7 are closed, the passengers in the hall 1 are not in contact with the vehicle 25, and the safety of the passengers is secured. The closing speed varies depending on the weight of the landing doors 6 and 7, but the closing speed is adjusted by changing the number of cold-rolled steel sheets of the closing weights 19 and 20 or changing the mounting position.

On the other hand, since the landing doors 6 and 7 are configured to be opened and closed by the links 13 and 14 disposed above the landing doors 6, 7 for closing, which are attached to the links 13 and 14 via the support arms 17 and 18, respectively. The weights 19 and 20 are located above the landing doors 6 and 7. Therefore, the support arms 17 and 18 and the closing weights 19 and 20 do not partially block the landing doors 6 and 7.
