BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide apparatus, and more particularly to a guide indicator apparatus in which the guide indicators are arranged in a strip form along a coated surface.

It is necessary to guide people from one place to another in a structure.

Such a guide device includes an emergency signal device for quickly guiding to an emergency exit side in case of an emergency along with a constant guide device for guiding a person in a structure.

Structures in which these devices will be used include fixed structures that gather in the public, such as hospitals, offices, or hotels, and structures for transport such as ships, trains, buses, and airplanes.

In these types of structures, suitable locations on which these guides can be placed are the floor and walls of the structure.

In the case of the flight indication signal of the airplane, as shown in US Pat. No. 4,347,499, it is known that the floor is suitable as a place which is less disturbed by cigarette smoke than the wall or ceiling of the structure.

It is desirable to use these “floor mounted” emergency indicators in accordance with the provisions of the FAA.

See D. Massey's ＂FAA's Floor Lighting Rule Opens Market to Suppliers＂ Commuter Air, page 46 (June 1986).

It is therefore an object of the present invention to provide a guide light apparatus suitable for installation under the floor or wall in order to provide a display means which can be electrically operated to emit light and is visible to the eye.

Another object of the present invention is to provide a guide light apparatus for floor installation in a structure suitable for use as a guide means for a person in the structure.

A special object of the present invention is to provide a guide light suitable for installation under a carpet.

The above and other objects of the present invention can be achieved or attained in the embodiment described as a light on a strip which allows the light to be visually installed along a covering surface, such as a carpeted floor, with the advantages of the present invention.

The light on the strip consists of a long, flexible, plastic sheet of ribbon with a series of electrical leads embedded at regular intervals laterally.

A series of translucent plastic housings are longitudinally disposed along the common outer surface of the ribbon of plastic sheet material.

Light emitting means are disposed in each housing and electrically connected to the selected one of a series of conductors embedded in a ribbon of sheet material.

Also provided in the present invention is a device for guiding a person through a passageway along a floor in a structure.

Such a device consists of a carpet covering the floor and a strip-shaped light as mentioned above extending below the carpet.

The carpet has a number of through holes corresponding to the series of translucent housings in the strip-shaped indicators arranged in a straight line.

The housing is arranged in the through-hole of the carpet so that the passage marks can appear along the surface of the carpet when the light emitting means arranged in the housing emits light.

The above-mentioned devices can be used by electrically connecting a series of conductors to a power source within a structure with such a passageway and adjacent to the passageway for marking passages at the bottom of the passageway so that people in the structure can find the exit. have.

The material which forms the long, flexible ribbon of the plastic sheet material used for the light on a strip is a material with relatively high toughness.

This toughness confers flexural rigidity in the longitudinal or widthwise direction of the ribbon to help excrete the ribbon in a straight line along the bottom surface.

This feature has the advantage of greatly simplifying the arrangement or installation of the strip light.

Moreover, because this material is a relatively tough material, it gives enough flexibility to roll or store the thin sheet constituting the strip-shaped indicator in the form of a roll.

Referring to the present invention in more detail based on the accompanying drawings as follows.

1 shows a passenger plane 10 in which the present invention is embodied.

The airliner consists of a cabin 11 with a floor 12, a number of seats 13 arranged on the floor, and a passage 14 extending across the center of the cabin.

The emergency exit 15 is located near the passage as shown in FIG.

In FIG. 1, a carpet 16 is laid at the bottom of the passageway and a strip-shaped indicator light 17 extends below the carpet.

The strip-shaped indicator 17, which is explained in more detail in FIG. 3, consists of a long, flexible ribbon of plastic sheet material.

This elongated ribbon is composed of united upper and lower plastic sheets 18 and 19.

Suitable materials for such plastic sheets include aromatic polyimides such as CAPTON® (manufactured by DuPont).

Other materials include polyethylene terephthalate such as " MYLAR " (also manufactured by DuPont) although the fire resistance is poor.

A tape-shaped metal ribbon 20 made of copper is embedded between the upper and lower sheets of the ribbon at regular intervals in the lateral direction.

This copper metal was coated with tin for corrosion resistance.

The electrical lead extends in the longitudinal direction of the sheet material ribbon.

A series of translucent plastic housings 21 are arranged on the top surface of the sheet material ribbon (see FIG. 1).

This housing is bonded to the ribbon with a suitable adhesive, such as a cyanoacrylate adhesive.

Suitable materials for the light transmissive housing include polycarbonates such as Duplex's “LEXAN”.

The housing is colored with a clear or thin liquid.

The housing is arranged longitudinally on a common wire among the tape-shaped metal wires, and is preferably disposed at a small distance of about 6 inches.

Carpets laid on the strip-shaped indicators are perforated through the holes 22, which are aligned in line with the arrangement of a series of translucent housings connected to the sheet material ribbon.

The diameter of the through hole formed in the carpet is equal to or slightly smaller than the outer diameter of the housing so that the housing can be elastically inserted therein.

4 and 5 show the translucent housing 21 disposed in the through-hole 22 extending through the carpet by removing a portion of the carpet.

The carpet is cut pile fabric 23 and the first reinforcing paper 24 is connected to the cut pile fabric and the second reinforcing paper 25 is bonded to the lower side of the first reinforcing paper to serve as a cushion layer.

The plastic housing 21 has a flange 26 extending laterally outward underneath (FIG. 6).

The flange forms an enlarger portion 27 for easily adhering the housing to the ribbon of the plastic sheet material and secures the housing so that the housing is not pulled upward through the through hole of the carpet.

The upper part 29 of the housing is curved so as not to be caught by a shoe.

When placed underneath the carpet, the upper portion 29 of the housing is slightly recessed from the surface 30 of the carpet so that when the carpet is compressed to an average weight, the carpet surface and the upper surface of the housing become substantially coincident.

The housing is formed with a space 31 open to the bottom side thereof (see FIG. 6).

A groove 32 is formed in the bottom of the housing and extends from the space portion to the outer edge of the flange.

A small incandescent lamp 33 (also referred to as a wheat grain bulb only by the size of a grain of wheat) is inserted into the space portion of the light transmissive housing.

This bulb has two leads 34, 35 which extend through each groove formed in the base of the housing when the housing is mounted on the ribbon (see FIG. 5).

The uniaxial conductor 35 is soldered to the tape-shaped conductor 20a at the lower side of the housing (FIG. 5), and the other conductor is connected to one of the conductors 20b (FIG. 4 and 5) predetermined in advance among the remaining tape-like conductors. It is electrically connected.

This electrical connection is made by soldering a short insulated conductor 36 between the conductor and the tape-like conductor (see Figure 4).

Of course, all electrical connections are made through the top layer of sheet material.

The conductive wire 34 and the insulated wire 36 are fixed to the ribbon of the plastic sheet material with the insulating tape 37.

The other conductive wire 35 is also deposited by the insulating tape 38.

Those skilled in the art will appreciate that such electrical connections are made in a number of ways.

For example, insulated wire can be replaced with a conductor printed with an electrically conductive ink.

7 is a schematic circuit diagram showing a device of the present invention showing a plurality of incandescent lamps 33.

This figure shows that one of the pairs of conductors extending from each incandescent bulb is connected to the common conductor 20a of the tape-like conductor of one conductor.

The translucent housing rests on this common tape-shaped lead.

Each pair of different conductors is electrically connected to a tape-like conductor close to the common conductor among the tape-like conductors.

One of the other pairs of conductors is electrically connected to the tape-shaped conductors across one compartment from the common conductor in turn.

In this arrangement, the light emitting means can be operated in sequence to present a guiding direction to a person.

Nine successive light bulbs are connected to each lead 20b-20j of the tape-shaped metal lead in a predetermined display pattern.

This display pattern repeats itself throughout the entire length of the light on the strip.

In general, the length of the strip-shaped indicator can extend to 300 feet.

Such devices include a low voltage power source 39, such as a 6 volt AC power source powered from a transformer and supplemented with a 6 volt DC battery.

Auxiliary batteries should be kept in trickle chargers.

Also, for safety, the light emitting means can be operated only by direct current from the trickle-charged battery.

If the light emitting means is operated in sequence, as shown, the sequence device 40 is connected between the power supply and each tape-shaped metal lead.

Finally, the actuator 41 can be connected as shown in FIG. 7 so that proper operation can be made.

Such devices are known.

7 may also be provided with metal conductors 20k which are continuously operated during the operation of the device in addition to the common metal conductors 20a and in addition to the metal conductors 20b-20j which are operated in sequence. have.

The lead wire 20k is electrically connected to the lead of the auxiliary indicator light 42 along the common lead 20a, and the auxiliary light 42 is part of the entire floor-mounted indicator device but is not operated in sequence. Lights up.

The number of metal conductors used for the strip-shaped indicators can vary as needed.

An example of an auxiliary light that is continuously lit is shown in the arrow-shaped floor-mounted auxiliary light 42 shown in FIG.

Such auxiliary lamps may be constructed in the same manner as described in the US Patent Application No. 869,001, or may be constructed by disposing a plurality of bulbs in the space formed in the housing by the same basic method as the translucent housing of the present invention. have.

The strip-shaped indicator of the present invention can be installed in the basic carpet while the through hole in the carpet using a small die in the field.

The new carpets allow pre-holes to be manufactured with standard presses.

The carpet used in the present invention may be any type of carpet, including carpet tile form or roll form.

The invention has been described above in one typical embodiment.

Although not specifically mentioned, the present invention is not limited only to this embodiment, and the scope of the present invention will be set forth in the following claims.
