Description

[Detailed Description of the Invention] This invention relates to a swinging door device for an elevator in which a swinging door is provided at the entrance/exit of a hall.

Generally, a swinging door is provided with an automatic door-closing mechanism and a holding device that holds the swinging door in a fully open state. When a passenger using a wheelchair gets into a car from an elevator hall equipped with such a swinging door, it is easy to open the swinging door and hold it in the fully open position, but after getting into the car, the door is held in the fully open position. There was a problem that it was difficult to close the hinged door, and it took a long time to close the hinged door and start the car running.

The present invention aims to solve the above-mentioned drawbacks of this invention and to provide a swing door device for an elevator that allows a passenger in a wheelchair to easily close the door.

An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 is the elevator hoistway, 2 is the landing entrance/exit provided there, and 3 is the landing entrance/exit 2 on one side.
3a is a handle of the hinged door, 3b is a recess provided on the upper end surface of the hinged door 3 and has a hole 3c in the center, and 3d is a recess provided on the front side of the hinged door 3. A cam arranged corresponding to 3b,
3e is an opening on the back side of the hinged door 3, and is provided in the vertical direction at an intermediate position of the height of the hinged door 3 near the edge of the hinged end of the hinged door 3, that is, at the height of the normal hinged door handle as shown in FIG. 4 is a well-known door closing mechanism that urges the hinged door 3 in the closing direction; 5 is a holding device fixed to the edge of the landing entrance 2; 5a is a frame thereof; 5a is a frame 5a; 5c is the flange fixed to this, and 5d is the actuation rod 5 that is loosely inserted into it.
A compression coil spring is fitted to b and disposed between the collar 5c and the upper end of the frame 5a, 5e is a roller pivoted to the lower end of the operating rod 5b and corresponds to the recess 3b, and 6 is a hinged door. 3 is an operating device provided near the edge of the hinged end of the hinged door 3, 6a is an operating rod inserted through the support piece 6b and held so as to be slidable in the vertical direction, and 6c is the operating rod 6a. An operating portion whose lower end is bent and protrudes from the slot 3e; a pressing portion 6d is formed by bending the upper end of the operating rod 6a so that it can fit into the hole 3c and presses the roller 5e;
Reference numeral 7 designates a holding detection switch which is mounted on the frame 5a and is disposed in the operating section facing the upper end of the operating rod 5b. 7a is a normally closed contact of this switch, 8 is a timed relay, and 8a is a switch of this switch. Time-limited normally closed contact, 9
is an alarm device consisting of a buzzer, (+) (-) is a power supply,
10 is a car that runs on the hoistway 1.

That is, the hinged door 3 is closed by the door closing mechanism 4, and at this time, the operating device 6 is placed in the lowered position by its own weight. Then, when the car 10 arrives at the entrance/exit of the hall, the hinged door 3 is closed by the passenger via the handle 3a. When the swing door 3 moves near the fully open position, the roller 5e is pushed up by the cam 3d, and when the swing door 3 reaches the fully open position, the spring 5d presses the roller 5e against the recess 3b. As a result, the hinged door 3 is held in the fully open position by the holding device 5 against the door closing force of the door closing mechanism 4. When a passenger gets into the car 10 in this state and pushes up the operating part 6c, the pressing part 6d rises from the hole 3c and pushes up the roller 5e. As a result, the holding of the holding device 5 is released, and the swinging door 3 is automatically closed by the door closing mechanism 4. As shown in FIG. 1, the operating section 6c of the operating device 6 is located near the edge of the landing entrance 2, so even a passenger using a wheelchair can use the operating section 6c, for example, while sitting in a wheelchair and facing toward the back of the car 10. Even if there is a problem, the operation section 6c can be easily operated. Therefore, the swing door 3 can be closed and the car 10 can be driven by a simple operation. Further, when the hinged door 3 is closed, the holding detection switch 7 becomes inactive, the contact 7a is closed, and the time relay 8 is energized by the (+)-7a-8-(-) circuit, and the contact 8a is closed. It will be released. When the hinged door 3 is held in the fully open position, the contact 7a is opened, so the time relay 8 is deenergized and the contact 8a is closed after a predetermined time has elapsed. As a result, the alarm device 9 is energized by the (+)-8a-9-(-) circuit, prompting the passenger to close the hinged door 3, and warning that the passenger has forgotten to close it.

As explained above, this idea has a door closing mechanism,
An operating device for a swinging door equipped with a holding device that holds the door in the fully open position, with an operating section located at a position equivalent to the height of the normal handle on the back side of the edge near the pivoted end of the swinging door, and releasing the holding of the holding device by manual operation. The apparatus is also provided with an alarm device which is activated via a timer after the holding detection device is activated by the holding operation of the holding device. As a result, even a passenger using a wheelchair can easily close and close the hinged door via the operating section of the operating device, making it convenient to use.
Furthermore, the present invention provides an elevator swinging door device in which a warning device warns of forgetting to close the swinging door, thereby preventing a situation in which the elevator cannot be operated due to forgetting to close the door.
