Abstract

PURPOSE:To prevent forgetting to shut the door by detecting open-and-close condition of a door of a manually operated and closed elevator by a sensor, starting a timer simultaneously with opening the door, and giving a warning when a door shut signal is not given until a designated time elapses. CONSTITUTION:A door 12a of a cage 1 of an easy elevator for a personal house, which is adapted to elevate the first floor-the third floor, for example and doors 6-8 of the respective floors are manually opened and closed. The cage 1 is elevated by a pulley 2, a rope 2a, a winding drum 3, a motor 5 and a speed reducer 4. When detecting means 51 detect opening of the respective doors 6-8 and 12a, timer means 52 are started. When the closing of every door is detected within a designated time, the timer means 52 are turned off, but when a door shut signal is given until time is counted up, warning means 54 are driven through control means 53, whereby a warning is given by a buzzer disposed on the upper portion of the cage 1. Thus, forgetting to shut the door can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Application The present invention relates to a prevention device for preventing forgetting to close a manual door in a private residential elevator having a manual door.

[Conventional technology]

In general, in general passenger elevators for buildings, as shown in Japanese Patent Laid-Open No. 60-197574, it is customary to open and close the doors automatically. The door will automatically close after a predetermined period of time has elapsed, and forgetting to close the door will not be a problem unless the control device malfunctions.

However, in recent years, with the arrival of an aging society and the spread of three-story houses, elevators have been installed in private residences, and doors for private residences are now being opened manually.

(Problems to be Solved by the Invention) Incidentally, in elevators having manual doors, forgetting to close the doors poses a major problem. That is, for safety reasons, elevators are usually provided with an interlock circuit that prevents the elevator from moving up or down unless the door is closed. For this reason, if an elevator with a manual door is forgotten to close, the elevator will not move even if a call signal is input from another floor.
There is a problem that it becomes extremely difficult to use.

The present invention has been made to solve this problem, and an object of the present invention is to provide a device for preventing forgetting to close a door of an elevator for a private residence, which can effectively prevent forgetting to close a manual door.

[Means to solve the problem]

The device for preventing forgetting to close the door of an elevator for a private residence according to the present invention includes a detection means for detecting the open/closed state of a manual door of an elevator for a private residence, and a detection means that is set by inputting a door open signal from the detection means. This configuration includes a timer means that is reset by a door closing signal from the timer means, and a control means that activates an alarm means provided in the elevator car by inputting a time-up signal from the timer means.

[Effect]

In this invention, the detection means detects whether the manual door is open or closed, and the timer means is set by the input of the door open signal from the detection means, and the input of the door close signal from the detection means. The timer means is reset. And after the timer means are set,
If the door close signal is not input within the set time, a time-up signal is output from the timer means, and the alarm means provided in the elevator car is driven by the control means.

For this reason, forgetting to close the door is effectively prevented.

Further, by using the above-mentioned alarm means also as an alarm means used in the event of an abnormality, the device configuration is simplified.

It is determined whether (7) and (8) are open or closed. Specifically, each limit switch (23).

It is determined whether (24) and (25) are ONh)OFF.

If any of the manual doors (8), (7), (8) is open, it is determined in step (35) whether or not the timer has timed up, and if the timer has timed up, step (36) Set the alarm buzzer (12) with . Also, if the time-up does not occur, step (37)
It is determined whether or not the timer is in operation. If it is in operation, the timer is incremented in step (38), and if it is not in operation, the timer is set in step (39).

Meanwhile, in step (34) manual doors (6), (7)
, (8) are closed, the alarm buzzer (12) is stopped in step (40), and the timer is reset in step (41).

In addition, in the above embodiment, the manual door (
8), (7), and (8) are closed or not, and if they are closed, the alarm buzzer (12) is stopped, but in step (36) the alarm buzzer is - (12) may be set and then the alarm buzzer (12,) may be stopped after a certain period of time has elapsed. Further, instead of the alarm buzzer (12), a chime or an audio output device may be used, or a flashing light may be used in combination with these.

(Effects of the Invention) As described above, in the present invention, the alarm means is activated by inputting a time-up signal from the timer means, so that forgetting to close the manual door can be reliably prevented. In addition, since the alarm means is installed in the elevator car, only one alarm is required regardless of the number of floors in the house.
Moreover, since the elevator car is stopped at the floor where the door is forgotten to be closed, an accurate warning can be given to the user. In addition, by making this alarm means also serve as an alarm means for abnormal situations, it is necessary to provide an alarm means for abnormal situations, so a device to prevent forgetting to close the door can be realized without adding the same amount of hardware. There are effects such as being able to do it.
