Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an aluminum handrail with a flocking process.

[0002]

[Prior art]

 Aluminum is also used as a handrail because it is lightweight, has good workability, and has excellent durability. In addition, many of them are surface-treated to prevent corrosion and improve their appearance, and they have the feature that they do not require painting work after construction. However, because of the cold texture unique to aluminum, the texture was hard and cold, and only a cold appearance and feel was obtained, which was sometimes uncomfortable and inferior in terms of decorativeness.

Therefore, conventionally, in order to alleviate the above points, synthetic resin or wooden pipe-shaped handrails have been used. There is also a handrail made of aluminum with a colored coating to give a decorative effect. Furthermore, a plurality of recessed grooves are provided along the entire length of the aluminum handrail main body in the longitudinal direction, and a colored synthetic resin strip material is fitted into the recessed grooves to give decorativeness (Act. No. 42436) or a handrail made by immersing an aluminum pipe in a molten synthetic resin liquid to form a synthetic resin layer on the outer periphery of the pipe (invention No. 61-13736).

[0004]

[Problems to be solved by the device]

 However, the aluminum handrail, which is simply colored and painted on the background, has a drawback that it is flat and that the painted part peels off in a short period of time. In addition, the desired heat insulation was not obtained.

On the other hand, an aluminum handrail in which a synthetic resin strip is fitted or whose outer periphery is covered with a synthetic resin layer has a hard and cold handrail, and almost no warmth can be felt. The surface was also easily scratched and its repair was almost impossible. In addition, manufacturing was complicated and uneconomical.

Since aluminum is inferior in heat insulating property, a plastic shape material or a wooden material may be used, but it has drawbacks in strength, durability, light resistance and the like.

In view of the above-mentioned circumstances, the present invention has a very good heat insulating property due to the flocking, and has a warm feeling similar to that of a carpet when viewed or touched with a hand. In addition, the flocked aluminum has good flocking adhesion and is suitable for partial attachment in terms of appearance and securing the flocking fixation, and is also excellent in fire resistance. The purpose was to provide handrails.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention forms a coating film by synthetic resin coating on the upper surface of the surface of an aluminum substrate on which an anodized film is applied, and a heat resistant pile is formed on the coating film. An aluminum handrail with flocked and flocked processing was constructed.

[0009]

[Action]

 Since the aluminum handrail is configured as described above, air is retained in the flocked layer, but since the coating film mainly blocks the conduction of heat, the heat retention of the air in the flocked layer is improved. , Exhibits extremely high heat insulation.

Regarding coating, a coating material having a good bond with a metal has been developed, and by forming a coating film with the coating material, the fixing property of the hair transplant can be enhanced. Therefore, there is no possibility that the flock will be removed from the end even if the flocking form is like partial attachment.

Examples of the paint that strongly binds to the oxide film of aluminum include fluororesin, delacron (melamine resin processing), acrylic resin, and the like.

Regarding the fire resistance, since the pile has heat resistance, even in the case of a fire, the flocked hair has a heat insulating property and the disadvantage that the aluminum melts is prevented as much as possible.

[0013]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 show an example in which the present invention is applied to an indoor aluminum base handrail P extruded into a pipe shape having a circular cross section. A coating film 3 is formed on the background 1 of the lumi substrate A, and flocked 5 is applied on the coating film 3. In FIG. 1, 2 is a support, 4 is a wall surface, 6 is a screw, and 8 is an anchor bolt.

Explaining the procedure of flocking, first, a coating of a fluororesin is applied by coating on the surface of a pipe made of an aluminum base material A having an anodized film on the surface to form a coating film 3.

After the paint is dried, the adhesive 9 is applied to the coating film 3 in order to attach the pile 7. For that purpose, a method such as a spray gun, a roll coater, a knife coater, dipping, and a brushing method is used.

To attach the pile 7, electrostatic flocking is performed. The flocking method includes an up-method method in which piles fly upward from below, a down-method method in which piles fly downward from above, an up-down-method method in which both methods are performed in the same manner, and a side-method method in which sideways fly. .

As a material of the pile 7, a material having excellent heat resistance such as nylon or carbon fiber is used. The pile 7 is generally colored with a dye. A special type is called so-called dying dyeing (raw material dyeing), in which the pigment is dissolved in the yarn at the stage of making the yarn. There are three types of gloss, bright (glossy), semi-dull (semi-glossy), and dull (matte). Such colors and luster are selected in consideration of harmony with the color of the underlying coating film 3.

It is not always necessary to implant hair on the support 2. However, if the coating film 3 of the same color as the flocked hair 5 is formed on the entire outer surface of the support 2, the handrail P having a good appearance and good appearance can be obtained. Further, the flocked hair 5 according to the present invention has no fear of being peeled off from its end even if it is partially applied.

[0020]

[Effect of device]

 As described above, according to the handrail made of flocked aluminum of the present invention, the synthetic resin coating film is formed on the upper surface of the base of the aluminum base material, and the heat-resistant pile is formed on the coating film. Since the hair is planted, it has the following excellent effects.

1) There is an advantage that the human being has a warm feeling similar to that of a carpet, even if it is visually or touched, and that any color other than gold and silver can be freely selected.

2) Even if the material aluminum is a defective product (scratch on the surface), it can be used as a satisfactory product because the flocked hair covers the surface, and it is economically and environmentally friendly. Is also preferable.

3) Further, even if the surface is repaired, there is an advantage that it can be easily done by attaching a flocked sheet.

4) Since the coating film mainly blocks heat conduction, the heat-retaining property of air in the flocked layer becomes good, and the heat insulating property is very high.

5) Since the flocking is performed on the synthetic resin coating film, the fixing property of the flocking can be enhanced. Therefore, even if the flocking form is like partial sticking, there is no fear that the flocking will come off from the edge, and the handrail excellent in design can be obtained by the harmony of the color of the coating film and the graceful texture of the flocking.

6) If the coating film has the same color tone as the flock, even if the flock is worn out, the color is complemented by the shade of the base, so that it is not conspicuous and the durability is improved in appearance.

7) Since the pile has heat resistance, even in the unlikely event of a fire, the flocked hair retains heat insulation properties and prevents the inconvenience that aluminum melts, so the fire resistance is very good.

8) As described above, the handrail of the present invention is excellent in touch, aesthetics, economy, workability, heat insulation, and noncombustibility.
