JPH0356387A - Luggage elevator - Google Patents

Abstract

PURPOSE:To unnecessitate the attendance of a porter during the conveyance of a luggage by an elevator so as to improve work efficiency by providing a cage with a lockable box for enclosing a luggage and constructing this lockable box in such a way that the lock thereof is released only when the cage stops at a specific floor. CONSTITUTION:A drawer 8 with a luggage enclosed therein is pulled out by the release of an electromagnetic lock 10 only when a cage 4 stops at a specific floor. Attendance is not therefore required during the conveyance of the luggage by an elevator, as well as a burglary accident due to an emergency stop other than the specific floor can be prevented.

Description

[Detailed description of the invention] [Purpose of the invention] (Industry” second field of use) The present invention relates to a luggage elevator.

(Prior art) Traditionally, small precious metals such as coins (hereinafter referred to as luggage)
When transporting items such as items within a building using an elevator, the person carrying them either holds them in their hands or places them on a wheelbarrow, etc., and stays close to the item and watches over it from beginning to end. In other words,
A transporter was also required during transportation by elevator.

(Problem to be solved by the invention) Therefore, it is not possible to carry out other work while the cargo is being transported, which is one of the causes of lower work efficiency.

On the other hand, if no person is present, there is a risk that someone else will stop the elevator while the elevator is being transported, leading to a theft accident in which the luggage is stolen.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cargo elevator that does not require the assistance of a transporter during transport and can transport cargo safely.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a cargo elevator equipped with a car that moves up and down in a hoistway via a drive device, in which a drawer for storing cargo is provided in the car, and , this drawer is unlocked only when the car stops at a specific floor.

(Function) The drawer containing the luggage can be unlocked and pulled out only when the car stops at a specific floor. This eliminates the need for an attendant while the luggage is being transported in the elevator. Furthermore, theft accidents due to emergency stops on floors other than those on specific floors can be prevented.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional view showing one embodiment of the present invention, and FIG.
The figure is a perspective view showing essential parts of an embodiment of the present invention.

In Figs. 1 and 2, 1 is a hoistway, and an entrance/exit 2 is provided on the floor, and in this entrance/exit 2, a door opening/closing device ( A door 3 that is opened and closed by a door (not shown) is provided. The car 4 is moved up and down within the hoistway 1 via a main rope 5 by a drive device (not shown).

A drawer box 6 is integrally attached to the basket 4 with screws 7. The drawer box 6 is provided with guides (not shown) along the front-rear direction on the inner surfaces of both sides, and the drawer 8 is inserted through the guides.
is installed. The drawer 8 is attached to the drawer box 6 so that it can be manually pulled out from inside the car 4 to the landing side by grasping the handle 9.

This drawer box 6 includes an electromagnetic lock 10 on the inner surface of the back side, which has a locking member that is displaced by energizing and deenergizing the coil.
is installed, and the drawer 8 is electrically locked and unlocked by signals from the operating system circuit. This unlocking is performed by registering a specific floor in the floor selection relay provided on the control panel (not shown) that controls the elevator, and then the car 4 stops at this specific floor level and the door 3 of the entrance/exit 2 opens. When the door is opened and the door opening detection switch 1l is opened, the electromagnetic lock is also released by a locking device release signal. or,
Locking is performed by inserting the drawer 8 into the drawer box 6, closing the door 3 of the opening 2, and locking the electromagnetic lock 10 again when the door opening detection switch 11 is closed.

On the other hand, in addition to the electromagnetic lock 10 described above, a mechanical lock 12 may be installed in the drawer 8 and locked and unlocked using an attached key, which is effective for long-term locking. As described above, an electrical or mechanical lock box is configured inside the car 4.

Next, the operation of the embodiment with the above structure will be explained. First, on the luggage delivery floor, load the luggage into the drawer 8, insert it into the drawer box 6, and press the switch on the hall operation panel (not shown) attached to the edge of the slot 2. As shown in Figure 3, the specific floor is registered, and the electromagnetic lock 10 is locked when the door 3 is closed and the door opening detection switch l1 is closed.
The drive device (not shown) starts and stops the car 4 within the level of a specific floor (stopping at a level is based on a steady operation circuit, so an explanation of determining whether it is inside or outside the level will be omitted).
let When the car 4 stops and the door 3 opens, the door open detection switch 1 operates to unlock the electromagnetic lock 1o. Therefore, the drawer 8 can be pulled out from the drawer box 6 and the loaded cargo can be taken out.

After that, when the drawer 8 is inserted into the drawer box 6 and a switch on the hall operation panel (not shown) is pressed, a new specific floor is registered, and the door 3 is closed and the door opening detection switch 11 is closed. The lock 10 is locked and the car 544 is stopped within the new specific floor level by means of a drive (not shown).

On the other hand, the mechanical lock 12 locks the car 4 regardless of the operating circuit.
If the door is stopped at a certain level, it can be locked and unlocked at will, which is effective for long-term locking.

Therefore, in the embodiment mentioned above, when the car stops at a specific floor,
Drawers can be taken in and out with normal movements without any other movements. In addition, since it is not possible to unlock floors other than specific floors even if there is an emergency stop, there is no problem with regular operation.

The present invention is not limited to the above embodiments, and the operation circuit may be equipped with a power outage countermeasure such as a storage battery so that it is effective even during a power outage. In addition, the installation location is not limited to the lower part of the car, it may be installed at any other arbitrary position, and the car may be lowered using a hydraulic cylinder.

[Effects of the Invention] As explained above, according to the present invention, the drawer is unlocked only when the vehicle stops at a specific floor 6.
To improve business efficiency by eliminating the need for a transporter to be accompanied during elevator transportation, and to provide a freight elevator capable of safely transporting luggage while preventing theft accidents.
