The door is never opened at positions other than a predetermined position. Unless the door opened at the predetermined position is closed, the lifting operation of the elevator cannot be performed. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

    The present invention relates to an elevator.

    Some conventional elevators have a plate-shaped sliding door type door, and some have an extendable screen door type door that can be seen through from inside and outside.

    Therefore, since the door of the conventional method can be opened and closed spatially regardless of the position of the elevator, the door can be opened even if it is not at the predetermined stop position due to malfunction of the control device or malfunction of the brake mechanism. This may cause an accident in which a user who does not notice the level difference between the elevator floor and the floor of the building falls or falls.

    Further, even when the user gets on and off the elevator, there is a possibility that the user may move up and down while the door is open due to a malfunction, which may cause a serious accident.

Problems to be solved by the invention

    In view of the conventional drawbacks as described above, the present invention does not open the door except in the normal stop position, and the elevator can be operated even if the control device malfunctions against the will of the user when the door is open. The purpose is to provide a safe elevator that does not start.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying documents.
However, the drawings are for explanation only, and do not limit the technical scope of the present invention.

Means for solving the problem

    In order to achieve the above object, the present invention is configured such that a door attached to a hinge on one or both sides of an elevator door opens to the outside of the elevator body with the hinge as a fulcrum.

    The present invention will be described below with reference to embodiments shown in the drawings.

    In the first embodiment of the present invention shown in FIG. 1 to FIG. 4, the elevator body 1 is constituted by a door 2 that opens and closes outwardly with a hinge 3 as a fulcrum on one side or both sides.

    FIG. 5 shows a state in which the door 2 cannot be opened to the outside when the elevator body 1 is not at the opening of the building 5 but at an inappropriate stop position.

    FIG. 6 shows a state in which the door 2 can be opened to the outside when the elevator is at an appropriate stop position. Even if the control device malfunctions and issues a signal for raising / lowering the drive device, Since it is locked by the door 2 and the building 5, it shows a state where it cannot move.

Different embodiments of the invention

    The second embodiment of the present invention shown in FIGS. 7 to 10 is different from the first embodiment of the present invention in that one door is vertically divided into a plurality of pieces and connected by hinges or hinges. The door 4 is opened and closed by the door 4, and the user can get on and off more smoothly by occupying less space.

The invention's effect

    As is apparent from the above description, the elevator equipped with the structure of the present invention guarantees the safety of the user against the malfunction of the control device which may not occur by any chance.
