Description

[0001] The present invention relates to a device for mounting a monitor on an elevator door,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitor fixing apparatus for an elevator door, and more particularly, to an apparatus for fixing a monitor for providing various information to an elevator door made of metal or glass.

1 is an overall schematic view for operating a car monitor (CM) installed in a cage or a car of an existing elevator. Since the conventional car monitor CM is installed inside the elevator cage, it is always necessary to move up and down like an elevator. In order to accommodate such up and down movements, a cable Is also integrated with a traveling cable (TC) for supplying power to the elevator, and this traveling cable (TC) is generally connected to a server computer of a remote control room.

Since the power line and the network line of the car monitor CM are connected to the traveling cable for the elevator cage in this way, they are bundled together with various other wires. Therefore, when a signal is supplied to the car monitor CM, signal interference with signals of other electric wires is apt to occur. Therefore, in many cases, the car monitor CM can not perform its function, TC), which makes installation and maintenance difficult and costly.

In addition, since the passenger can see the car monitor (CM) only while the passenger is traveling on the elevator, and moreover, only the target floor number is checked, the advertisement and information transmission effect through the car monitor (CM) to be.

SUMMARY OF THE INVENTION The present invention has been conceived in view of the above problems and it is an object of the present invention to provide a monitor in an elevator door that does not move up and down so that a separate connecting line can be fixed along a hoistway of an elevator without using a conventional traveling cable Thereby reducing installation and maintenance costs.

The present invention also provides a monitor on the elevator door to enable the elevator passenger to easily acquire various advertisements and information through the monitor during the time of waiting for the elevator to arrive, And to be able to obtain information.

The present invention also aims to provide a fixing device for fixing information providing means including such a monitor to an elevator door made of metal as well as a glass elevator door.

In order to accomplish the object of the present invention as described above, the present invention is characterized in that it is fixed to the rear surface of the door D on the rear side of the opening 15 of the elevator door D made of metal and projects to the rear side of the elevator door, A monitor box (MB) in the form of a rectangular parallelepiped for storing therein;

A monitor (M) fixed in the monitor box (MB);

A tempered glass plate (20) disposed behind the opening (15) of the elevator door (D) and having a size covering the entire monitor to protect the monitor (M) from impact on the front surface;

Reinforced glass plate fixing means (30) for fixing the tempered glass plate (20) to the rear side of the elevator door (D) so as to cover the opening (15); And

And ventilation means (40) for discharging heat generated from the monitor (M) to the outside of the elevator door (D).

In the meantime, the present invention provides a monitor box MB (MB) which is fixed to the rear surface of an elevator door D fixed to a door frame 10 and is protruded to the rear side of the elevator door, );

A monitor (M) fixed in the monitor box (MB);

A horizontal reinforcing bar 30 installed at the upper and lower ends of the monitor box MB to fix the monitor box MB to the door frame 10;

A vertical reinforcing bar 32 vertically connecting the upper and lower horizontal side reinforcing bars 30 to fix the monitor box MB to the upper and lower side horizontal reinforcing bars 30; And

And ventilation means (40) for discharging the heat generated from the monitor (M) to the outside of the elevator door (D).

In the monitor fixing device of the present invention, the ventilation means 40 may include an air inlet 42 formed at the lower end of the monitor box MB and an air outlet 44 formed at the upper end of the monitor box MB.

According to the monitor fixing device of the elevator door of the present invention constructed as described above, the information providing means including the monitor can be easily fixed to the elevator door made of glass as well as the elevator door made of metal, The monitor can be replaced.

Fig. 2 is a schematic view showing an elevator hoistway and an elevator door D embodying the present invention and a passenger standing in front of the door. Fig. As shown in the drawings, according to the present invention, a passenger can acquire information through a monitor M provided on an elevator door D regardless of an elevator cage.

3 to 6 are views showing a first embodiment of the present invention. Specifically, the elevator door D is an embodiment in which the elevator door D is made of a general metal.

FIG. 3 is a front perspective view of a metal elevator door installed with a monitor, FIG. 4 is a rear perspective view of the door of FIG. 4, FIG. 5 is a sectional view taken along line V-V of FIG. 3, and FIG. 6 is a sectional view taken along line VI-VI of FIG.

As shown in the figure, an opening 15 is formed in the middle of the elevator door D made of metal, and a monitor box MB in the form of a rectangular parallelepiped is fixed to the rear side of the door D at the rear side of the opening. In this way, the monitor M is installed in the monitor box MB projecting to the rear side of the elevator door. Since it is general to fix the monitor M in the monitor box MB, detailed description is omitted. The screen of the monitor M installed in this manner can be seen from the front of the elevator door D through the opening 15.

Such a monitor M is susceptible to an external impact, particularly an impact from the front, and a means for protecting it is needed. Therefore, a tempered glass plate 20 is provided as a means for protecting the monitor behind the opening 15 of the elevator door D. The tempered glass plate 20 should be sized to cover the entire monitor to protect the monitor M from the impact of the front (see Figs. 5 to 6).

The tempered glass plate fixing means 30 is used to fix the tempered glass plate 20 to the rear side of the elevator door D so as to cover the opening 15. [ 5 to 6, the fixing means 30 extends along the edge of the tempered glass plate 20 and is fixed to the rear surface of the elevator door D with fasteners such as screws or bolts, .

On the other hand, since the monitor M generates considerable heat during operation, a ventilation means 40 for discharging such heat to the outside is required. Although it is preferable to use natural convection of air such as the air inlet 42 formed at the lower end of the monitor box MB and the air outlet 44 formed at the upper end of the monitor box MB as the ventilation means 40, Accordingly, a ventilator (not shown) may be installed inside or outside the monitor box MB to forcibly circulate the air.

Figs. 7 to 10 show a second embodiment of the present invention. In this case, the elevator door D is not made of metal but made of glass. Since the elevator door D is a glass plate, a means for fixing the monitor box MB to the metal door frame 10 is separately required, and the structure of the first embodiment is not required, Similar.

That is, since the monitor box MB which is the same as or similar to the first embodiment can not be fixed to the glass door D, it must be fixed to the door frame 10. To this end, the horizontal reinforcing bars 30 are disposed at the upper and lower ends of the monitor box MB, respectively, and both end portions of the horizontal reinforcing bars are fixed to the door frame 10. As a means for fixing the monitor box MB to the upper and lower end horizontal reinforcing bars 30, a vertical reinforcing bar 32 is vertically provided between the upper and lower end horizontal reinforcing bars 30, and a monitor box MB).

If necessary, the back sheet 12 may be attached to the entire rear surface of the door D of the other portion except the portion for exposing the monitor M to the front of the door D. The backsheet 12 may be transparent, translucent, or colored.

Other structures are similar to those of the first embodiment and thus will not be described.
