Description

Photovoltaic device installation structure of elevator {STRUCTURE FOR FOUNDING PHOTOELECTRICITY APPARATUS OF ELEVATOR}

The present invention relates to an elevator door that opens and closes in one direction, and more particularly, to an elevator photoelectric device installation structure which detects the presence of a passenger when the door is closed and reopens the door.

In general, an elevator door is opened and closed by a door driving device. The door driving device is a car door driving device mounted on a car on which a passenger rides to drive a car door, and a driving force of the car door mounted on a building side. It is divided into an entrance door driving device that opens and closes the entrance door, and the entrance door is driven in connection with the car door.

However, since the elevator door opened and closed by the door driving device operates in direct contact with a passenger, a thorough examination of safety accidents should be made. A safety device for preventing such safety accidents is installed to be interlocked with the door. It is a contact detection bar that operates when contacting the passenger at the moment of closing and reopens the door, and a light emitting sensor and a light receiving sensor that transmit the beam when the door is closed and detect the entry of the passenger without the door touching the passenger and reopen the door. There is a photoelectric device made.

Conventional elevator doors equipped with such safety devices are illustrated in FIGS. 1 to 4, which will be described below.

A drive link (1) is installed on the upper side of the conventional elevator door to open and close the door (D1) when the passengers and cargo ride and unload, and the door (1) at one end of the door (D1) to be interlocked when driving the door (D) The contact detection bar (SAFETY) 2 is installed in the vertical direction at the part in contact with the elevator vertical frame 3 forming the skeleton of D1) (D2) so that the contact detection bar 2 is closed when the door D1 is closed. Upon contact with the passenger, a micro switch (not shown) is operated to open the door D1 again, and the elevator is supported by the platform vertical frame 4 constituting the structure.

One end of the drive link 1 is fixedly connected to an engaging member (not shown) fixed to the door D1, and the engaging member is coupled to an elevator door (not shown) to form an operation of the driving link 1. When the door (D1) is opened and closed it acts to interlock and open the landing door.

On the other hand, the light emitting sensor (S1) is attached to the lower side of the platform vertical frame (4), one side of the door (D1) detects the light emitted from the light emitting sensor (S1) of the passenger entered into the car A light receiving sensor S2 is attached to a position and a height corresponding to the light emitting sensor S1 so as to detect the presence or absence thereof, and the contact detecting bar 2 and the elevator vertical frame 3 at the same position as the photoelectric device are provided. Each light emitting hole having a predetermined size is formed, and each light emitting hole transmits a beam emitted from the light emitting sensor S1 to prevent a safety accident caused by the light emitting hole and to enhance a design effect. The transparent lens 5 is attached to reach the light receiving sensor S2.

Therefore, when the passenger enters the inside of the car when the door D1 is closed, the light emitting sensor is located between the light emitting sensor S1 installed in the platform vertical frame 4 and the light receiving sensor S2 installed in the door D1. As the beam emitted from S1 does not reach the light receiving sensor S2, the door D1 is opened again.

However, in the prior art as described above, when the door D1 is driven, the contact detection bar 3 installed in the door D1 is also interlocked so that the beam emitted from the light emitting sensor S1 passes through the contact detection bar 3. In this case, the focus of the beam is not accurately bound to the light receiving sensor S2 due to the flow of the contact detecting bar 3, and thus there is a problem in that the function of the elevator safety device cannot be faithfully performed.

In addition, conventionally, the lens 5 is attached to the elevator vertical frame 3 so as to protrude, the lens 5 collides when the passengers get on and off, or damaged, or the passengers are hurt by the lens (5) There was this.

Accordingly, an object of the present invention is to provide a photovoltaic device installation structure of an elevator to achieve a safe getting on and off of passengers by preventing the focus mismatch between the light emitting sensor and the light receiving sensor in order to solve the above problems.

Another object of the present invention is to provide an elevator photovoltaic device installation structure for improving the aesthetics of the elevator by removing the lens protruding in the conventional vertical frame of the elevator, and also to prevent injury to passengers.

As shown in the figure, a drive link 11 for opening and closing the door D when the passengers and the cargoes are loaded and unloaded is fixedly installed on a mating member (not shown) connected to the landing door (not shown). One side end portion of the door D is vertically contacted with a part of the door vertical frame 13 which forms a frame of the door D so as to be interlocked with the door D when the door D is driven. The sensing bar (SAFETY) 12 is installed, the elevator vertical frame 14 is installed on one side of the elevator vertical frame 13 to form an elevator structure.

A light emitting sensor S1 is attached to a lower portion of the platform vertical frame 14, and a light emitted from the light emitting sensor S1 is sensed inside the door D1 to detect the presence of a passenger entering the car. The light receiving sensor S2 is attached to a position and a height corresponding to the light emitting sensor S1.

That is, the light receiving sensor S2 is installed inside the door D1 and is disposed so that the beam center of the light receiving sensor S2 coincides with the side center of the door D1 when viewed in plan view, and the light emitting sensor S1. The beam center is positioned on the landing vertical frame 14 at a position coinciding with the beam center of the light receiving sensor S1.

The light emitting sensor S1 and the light receiving sensor S2 are fixed to the optoelectronic device support 15 with bolts B, and the optoelectronic device support 15 is also door D and the boarding point respectively by the bolt B. It is fixed to the vertical frame 14.

In addition, as shown in FIGS. 7 and 8, the elevator vertical frame 13 at the side surface of the door D1 and the position corresponding to the photoelectric device S1 and S2 is provided from the light emitting sensor S1. A plurality of light emitting holes 16 and 13a each having a predetermined diameter are formed so that the emitted beam passes through and reaches the light receiving sensor S2.
