Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handrail lighting device for a passenger conveyor such as an escalator, and more particularly to a handrail lighting device suitable for dissipating lamp lighting heat.

In general, the design of a passenger conveyor is evaluated by the part of the railing that exposes the entire figure, so this part includes expensive glass panels that emphasize transparency, brightly colored handrails, and beautifully decorated railings. It is common for a deck to be installed to create a more unique and innovative design effect.

In addition to the above-mentioned design effects, it is well known that the installation of handrail lighting that brightly illuminates the feet of passengers and helps them get on and off the train is widely adopted as an important design point.

As described above, it is easy to understand that the design quality of a passenger conveyor is judged by the overall design of each part of the railing, and that this, along with its ability to transport people, is an important selling point of a passenger conveyor.

Here, the structure of a conventional passenger conveyor will be explained with reference to Figs. However, overall strength maintenance is left to the building floor 5 to which the passenger conveyor is attached.

The above-mentioned handrail section 4 is made of long materials that span the entire length of the passenger conveyor, such as guides 6, decks 7, glass panels 8, etc., which are fixed with bolts 6a to support the running of the handrail 2, and are made of long materials with appropriate intervals l1 and l2. The railing 4 is supported by pillars 9 having a width W1.

Further, a lamp 10 having a length corresponding to the spacing l1 and l2 between the pillars 9 is disposed in the space Z opening downward in the deck 7, and its base pin 10a is connected to a socket 11 located near the pillar 9. has been done.

The socket 11 is fixed to the deck 7 with screws 12, and is further connected to a lead wire 13 that passes through the interior 9a of the column 9 to supply electricity, thereby lighting the lamp 10.

On the other hand, around the lamp 10, there is provided a milky-white illumination cover 14 made of vinyl chloride, acrylic plate, or the like, and which usually has a light transmittance of about 80 to 90%.

This lighting cover 14 is attached to the deck 7 as shown in FIG.
Support piece 7a protrudes inward with width W2 at the lower side of
and 7b, it is first compressed from both sides as shown by arrows A and B to reduce its width, and then pushed upward as shown by arrow C, and finally the supporting piece 7 is compressed as shown by the phase line.
The most common configuration is to release the compressive force at the upper sides of a and 7b and allow the parts to elastically return to their original state before being attached.

Therefore, since the material of the lighting cover 14 is required to have the property of transmitting light rays and having a certain degree of elasticity, vinyl chloride or an acrylic plate as described above has been commonly used for a long time.

Further, as the type of lamp 10, an instant-start hot cathode fluorescent discharge lamp, generally referred to as a slimline lamp, is used.

The principle of this slim line lamp is that the discharge starts instantaneously by a faint discharge, and then the cation bombardment generated at that time heats the electrodes and immediately transforms into a solitary light discharge. (Figure R part),
Slimline lamps, which are good at curved irradiation, are most suitable for applications where lighting is done in a curved manner.Furthermore, they are highly reliable and widely used because they can be turned on instantaneously without the need for a growth tartar like regular fluorescent lamps. It is something.

In the railing configuration of a passenger conveyor equipped with lighting devices such as the lamp 10 and the lighting cover 14 as described above, discharge heat when lighting the lamp 10 is transferred to the lighting cover 14.
There is a problem that thermal deformation occurs, and a solution to this problem is desired.

This deformation phenomenon is caused by the lamp 10 emitting high heat while it is lit, increasing the temperature in the space Z of the deck 7 and the lighting cover 14 that almost completely blocks this space Z. When the light is on for about 10 hours a day, which is the average operating time of a passenger conveyor, the above temperature is 60 to 7.
It has been confirmed that temperatures can reach temperatures as high as 0 degrees.

In this case, the deck 7 is made of an aluminum alloy material, so it will not be deformed by heat, but the lighting cover 14 is made of a thermoplastic material, such as vinyl chloride, so it will noticeably soften and deform. Falling off from the bottom of the deck 7,
Furthermore, in the worst case scenario, there is a risk that the lighting cover 14 itself may burst into flames, so prompt action is required.

When considering the phenomenon of falling off due to such deformation, the following deficiencies are pointed out in the conventional balustrade structure.

That is, the direct cause of the deformation of the lighting cover 14 is that the lamp 10 emits high temperature when lit, but the lighting cover 14 completely covers the lower surface of the space Z that opens downward with a width W2 around the lamp 10. In addition, since both ends of the lighting cover 14 are partitioned by pillars 9 with a width of W1 (the pillar 9 closes the opening of the deck 7 with a width of W1 and W2), the space in which the lamp 10 exists is The structural problem of the building being almost completely sealed with little ventilation and gradually becoming hot cannot be overlooked.

In view of this point, the present invention has been made in order to promote heat dissipation of the above-mentioned lighting device and to provide a parapet lighting device that is free from problems such as falling off.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 5 and FIG. 6, glass panels 8 pillars 9,
The configuration of the lamp 10, socket 11, etc. is completely the same as the conventional one, but in the present invention, the illumination cover (corresponding to the conventional illumination cover 14) is divided into two illumination covers 15 and 16 in the longitudinal force direction l2, and A feature is that a cover 15a is attached to the end of one illumination cover 15 to cover the abutting portion of the two illumination covers and prevent light from leaking.

Here, the cover 15a is integrally joined (glued, etc.) to the illumination cover 15, and there is a slight gap Q between the adjacent illumination covers 16 at a distance l3, as shown in FIG. It is formed along.

Then, from the above distance l3 and gap Q, the lamp 10
The lighting heat is released as shown by arrow P.

Therefore, as mentioned above, the air in the space Z part, which is quite hot, circulates naturally, and as a result, problems such as the lighting heat of the lamp 10 deforming the lighting covers 15 and 16 are eliminated. be.

According to the present invention as described above, there is an advantage that it is possible to provide a parapet lighting device that is free from problems such as falling off of the lighting cover.

In addition, in the above-mentioned example, the gap Q1 interval l3 etc. was intentionally provided between the illumination cover 15 and the cover 15a and the illumination cover 16, but this is not limited to this.
As shown in the figure, there are gaps R1 and R that naturally occur due to work errors when installing these two lighting covers.
2 may be used to emit it as shown by the arrow P1.

In this way, the present invention divides the lighting cover into at least two parts between the pillars of the parapet, and furthermore, the end of one lighting cover is joined with a cover that covers the end of the adjacent lighting cover. All things belong to this range.
