DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illumination handrail capable of projecting natural heat.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No. 3-64789 discloses a known technique in which a handrail made of natural wood is provided with a lighting function.
Has been proposed, which is believed to be the closest approximation to the present invention.

[0003]

SUMMARY OF THE INVENTION In the case of this known invention,
A single groove (1a) extending in the longitudinal direction of the handrail body (1) having a circular or elliptical cross-section is cut out and arranged from a solid wood material, and is arranged along the groove (1a). And a plurality of micro lamps (small light bulbs) (2) are respectively inserted into sockets (4) interposed and distributed at predetermined intervals of the power cord (3). It is plugged and connected to the buried state, which is almost flush.

A separate packing material (5) such as rubber, wood, plastic or the like is also provided at the place where the groove (1a) is exposed between adjacent micro lamps (2). The power cord (3) is pressed down and covered so as to be almost flush with (1).

[0005]

However, the configuration of the above-mentioned known invention has the following problems.

That is, first, since the micro lamp (2) is in a state of being embedded in the groove (1), it is impossible to project the natural texture of the handrail body (1) made of wood material. As a result, the light projection direction of the microlamp (2) is limited to one direction in which the groove (1a) is opened, so that the construction of the bent handrail is particularly restricted.

Secondly, since each of the micro lamps (2) is exposed to the outside from the handrail body (1), even if the micro lamps (2) are flush with the surface thereof, they are in use at any location. It is easy to cause damage accident or theft accident.

Third, since each of the fillers (5) is also exposed to the outside from the handrail body (1), it is easy to encounter a breakage accident or a theft accident during use depending on the installation location. Depending on the material of the material (5), the wooden surface of the handrail body (1) and the appearance of the handrail give an uncomfortable feeling.

Fourth, a large number of micro lamps (2), their sockets (4), and fillers (5) are required, and each of these must be embedded or inserted, which greatly complicates the operation. Inferior in workability.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a first embodiment of the present invention; FIG. This figure shows a relatively short handrail (commonly referred to as a grip bar) for use near the bed in the bedroom. (10) is a hollow handrail body, (11) is a support bracket, and its receiving cylinder. (11a) receives the end of the handrail body (10) into the inside, and the mounting seat (11b) also has a plurality of screws (1).
2) and the like, it is attached and fixed to the wall surface (W) of the building.

In the case of the present invention, the handrail body (10) is made of a lightweight and high-strength FRP pipe (P) manufactured as described below. I have.

More specifically, in FIGS. 5 to 12 showing the manufacturing process, (13) is a fiber sheet prepreg used as a material of the FRP pipe (P), and is made of glass fiber, carbon fiber, aramid fiber, and other various fiber sheets Is previously impregnated with a thermosetting resin such as an epoxy resin, a phenol resin, or a polyester, and is formed in a semi-cured state (prepreg). (M) is a mandrel (die) having a circular cross section processed from iron or another metal round bar, and has a pair of journals (14) projecting from both ends.

Therefore, in manufacturing the FRP pipe (P) to be the handrail body (10) of the present invention, first, the mandrel (M) is rotated to apply the fiber sheet prepreg (13) to the surface thereof. Wrap as shown in FIGS. The number of windings (the number of plies) and the arrangement angle of the fibers are arbitrary, but in consideration of the durability of the handrail body (10) and the light transmittance of a lighting device described later, for example, the fiber sheet prepreg (13) is used. It is preferable that the thickness of the FRP tube (P) is set to about 2 mm by winding by 8 plies. The light transmittance of the lighting fixture can also be adjusted by the number of turns.

Next, the fiber sheet prepreg (13)
Thickness with natural heat treatment to cover the surface of
2 to 0.7 mm thin decorative veneer (so-called wood board) (15)
Is wound up by one ply as shown in FIGS.
At that time, the wound edges are kept in a state of overlapping by a certain amount (X) so that the seam of the decorative veneer (15) does not open unsightly later.

Then, a bleeder tape (16) having heat resistance and releasability is wound in a compacted state so that the surface of the decorative veneer (15) is continuously covered as shown in FIGS. A certain temperature (for example, about 130 ° C. to above) at which the thermosetting resin of the fiber sheet prepreg (13) can be thermally deformed.
The fiber sheet prepreg (13) is completely cured by inserting it into a heating furnace (not shown) for maintaining the fiber sheet prepreg (160 ° C.) for a required time.

In this case, the thermosetting resin impregnated in advance in the fiber sheet prepreg (13) is once softened by heating and becomes a fluid state, and the decorative veneer (15) is mixed therewith. However, as a result of being cured in a state in which they are fused together, a peeling interface such as through a secondary adhesive does not occur between them.

In this regard, it is particularly preferable to employ a phenol resin or another addition condensation type resin (formalin resin) as the thermosetting resin.
5) As the back surface, a buffer film (17) that can be impregnated with the above-mentioned thermosetting resin such as Japanese paper or non-woven fabric is previously attached and integrated, and this is used as the fiber sheet prepreg (13). It is desirable to wrap around the surface.

The above-mentioned addition condensation type resin undergoes a condensation reaction when the fiber sheet prepreg (13) is cured by heating, and accordingly water (H ₂ O) is separated and produced, and the water content is changed to a decorative veneer. In the case of (15), steaming acts on itself, and it is smoothly softened so that it adheres to the surface of the FRP pipe (P) in a well-adhered manner. Because you do.

More specifically, in the heating and curing process of the fiber sheet prepreg (13), the thermosetting resin once fluidized into a liquid state by the heating as shown in FIG. It penetrates from the fiber sheet forming the material into the buffer film (17) of the decorative veneer (15) and is impregnated into the tissue, and the decorative veneer (1)
5) and the fiber sheet of the FRP pipe (P) are tightly bound together.

Then, the thermosetting resin finally becomes an infusible hardened state and is not thermally deformed again.
There is no danger of the decorative veneer (15) peeling off from the fiber sheet of the P pipe (P), and excellent durability and light weight can be maintained. Moisture separated and generated by heating the above-mentioned addition condensation type resin, before its hardening, is applied to the decorative veneer (1).
It will evaporate itself from the surface of 5).

Although an epoxy resin is used in place of the addition condensation type resin such as the above-mentioned phenol resin, if sodium hydroxide is mixed with the epoxy resin, the same operation and effect as those described above can be achieved. Since the epoxy resin has flame retardancy corresponding to the self-extinguishing property of the phenol resin, it can be said that the epoxy resin is useful for manufacturing the FRP pipe (P) serving as the handrail body (10).

When the fiber sheet prepreg (13) is completely cured, it is removed from the heating furnace, cooled to room temperature, and then released from the mandrel (M) (core removal). And finally, the bleeder tape (1
It goes without saying that 6) is peeled off.

FIGS. 13 and 14 show the FRP pipe (P) manufactured in this manner. The cross-sectional shape is not limited to a circle, but can be formed into an ellipse or a semicircle. It is also possible to form the tapered shape whose thickness gradually changes from one end to the other end in the longitudinal direction.
Due to the tapered shape, a pedestrian can be guided in one direction for use as a handrail body described later.

In any case, the FRP pipe (P) is made of a fiber sheet prepreg (1) such as glass fiber or carbon fiber.
The decorative veneer (15), which is made of 3) and is fused and integrated into the surface by one ply in a coated state, is also a thin fibrous material cut in the form of a peel from a log, and therefore has light transmission. Has the property.

In the present invention, such an FRP tube (P) is cut into a required length to be used as a handrail main body (10), and into the hollow interior thereof, as shown in FIGS. , Which are turned on by supplying power from an external power supply, so as to project the natural texture of the decorative veneer (15).

As the lighting fixture (L), in particular, a uniform brightness over the entire length of the handrail body (10) is ensured, and the durability against vibration and impact is enhanced.
It is preferable to use light emitting diodes connected in parallel to a power source such as 5-19.

That is, (18) is a bendable insulating support member that is thinner than the handrail body (10), and is made of a plastic such as a transparent synthetic resin (preferably soft vinyl chloride resin) or rubber that functions as a reflective member. It is made in the form of a rope from an object, in which an electrode wire (19) consisting of a pair of parallel metal wires extending in the longitudinal direction is embedded and arranged.

Similarly, a large number of metal pins (20) are embedded in the insulating support member (18) at regular intervals in a relationship perpendicular to the two electrode wires (19). In other words, the insulating support member (18) can be smoothly bent as a bending fulcrum. The electrode wire (19) of the metal wire also serves to make the bent state.

Numerals (21) are a number of light emitting diodes embedded between adjacent metal pins (20) in a dotted distribution parallel to the metal pins (20). (22) is continuously unified along the longitudinal direction of the insulating support member (18) via the metal pin (20) serving as a protection resistor.

Moreover, the continuous unified lead wire (22) is connected to one of the electrode wires (19) at the base end of the insulating support member (18). Is connected to the other electrode wire (19) at the tip of the.

(23) is a pair of pin-shaped terminals inserted from the base end of the insulating support member (18) into a state of connection with both electrode wires (19), and (24) is a support member (18).
Is an end cap attached to the tip of the head, and is made of an insulating plastic such as synthetic resin or rubber.

Reference numeral (25) denotes a connector attached to the end of the power cord (26).
8) It is used by being freely inserted into and removed from a pin-like terminal (23) projecting from the base end. (27) is an insulative cover bush for covering the insertion portion, and the male screw (27a) of the large-diameter base end thereof cannot be detached from the connector (25) via the cap nut (28). While being fastened, the male screw (27b) having the same small diameter at the tip is further secured to the insulating support member (1) by another cap nut (29).
8) is also fastened irremovably. In addition, (27
c) is a split groove for reducing the diameter of the cover bush (27), which is provided at the small end of the cover bush (27).

In this case, in the embodiment shown in FIGS. 1 to 4, the wiring support member (18) for the lighting device (L) is supported by the handrail body (10) as a retrofitted lighting handrail for a toilet or a bathroom. Bracket (11) receiving cylinder (1
1a), the pin-like terminal (23) and the connector (25) of the power cord (26) are inserted and connected, and a plug (30) attached to the base end of the power cord (26) is inserted. A power switch (32) is inserted in the power outlet (31) and a lighting switch (32) is inserted in the middle of the power cord (26), as suggested by a modified embodiment of FIG. 20 corresponding to FIG. Then, the power supply cord (26) is passed through the hollow inside of the support bracket (11) of the handrail body (10), and is embedded and not exposed from the wall surface (W) of the building. Of course, only the lighting switch (32) may be mounted so as to be exposed on the wall surface (W) of the building.

Further, as the illuminating lamp (L) used for the illuminating handrail of the present invention, a plurality of heat-producing miniature bulbs (33) instead of the light emitting diodes (21) are adopted, as shown in FIG. Alternatively, the electrodes may be connected in parallel to the pair of electrode wires (19a) in a dotted distribution at regular intervals.

According to this, the handrail main body (10) is heated moderately warm by the miniature bulb (33) which is penetrated into the hollow interior and wired, so that the handrail can be used in winter or in cold regions. As a result, it is possible to give a suitable feeling in holding and using. The handrail body (10) is about 13
Since the fiber sheet prepreg (13) is made of the FRP tube (P) which does not melt unless heated at 0 ° C to 160 ° C, it is needless to say that it has heat resistance to the miniature bulb (33).

FIGS. 22 and 23 show a second embodiment of the present invention, which is a relatively long handrail for guiding a walk, which is used in indoor and outdoor stairs, hospital corridors, hotel gardens, mountain roads, parks and the like. However, in this case, the support (34) instead of the support bracket (11) of the first embodiment may be erected from the ground or the floor (F) of the building, and the support (34) may be used. The power cord (26) passes through the hollow inside of ()) and is wired. Since other configurations are substantially the same as those of the first embodiment, FIGS.
Only the reference numeral corresponding to 20 is entered, and a detailed description thereof will be omitted.
