Description

TECHNICAL FIELD The present invention relates to a method for manufacturing a door and a door frame, and more particularly to a door and a door frame for constructing a toilet booth or other partition, and a method for manufacturing them with high quality and low cost. It is about the method.

A toilet booth is a partition that forms a private toilet space, and is installed in public facilities, office buildings, hospitals, etc., and is composed of a door, door frames on both sides of the door, and a depth panel. In many cases, a metal edge material such as aluminum or stainless steel is attached to the edge (timber edge) of the door and door frame to protect the panel butt edge. In the past, most door frames had the same height as the door, but these days, they are often made to reach the ceiling.

In any of the above types of toilet booths, the metal edging of the door and door frame is exposed, but needless to say, the metal edging is bland, cold, aesthetically pleasing and soft. It is far from the texture. The same applies to partitions other than toilet booths.

Japanese Patent Application Laid-Open No. 2018-3389

As mentioned above, many of the conventional common toilet booths have door and door frame edges made of metal such as aluminum or stainless steel, so they feel dull and cold, and are far from aesthetic and soft textures. And from there, no comfortable rest space can be created. Therefore, it is conceivable to attach a common decorative resin sheet to the door, the door frame, and their edge material to give them a sense of unity.

However, in that case, resin decorative sheets with a wide variety of colors, patterns, and patterns are prepared, but these are adhesive-attached decorative sheets having an adhesive layer on the back surface, which increases the cost. In addition, since the adhesive maintains a gel state, the adhesive may stretch and the adhesive-attached decorative sheet as an adherend may gradually slip and move, impairing the appearance.

The present invention has been made in view of the problems associated with the use of such a decorative sheet with an adhesive. An object of the present invention is to provide a door frame and a method for manufacturing the door and the door frame, which can manufacture the door and the door frame with high quality and low cost.

The invention according to claim 1 for solving the above problems is a door and a door frame comprising a panel and an edge material fitted to the butt end thereof,
A door and a door, wherein a resin decorative sheet having no adhesive layer is attached to the back surface of the panel via an adhesive, and a decorative sheet with an adhesive is attached to the edge member. It's a frame.

The invention according to claim 4 for solving the above problem is a method for manufacturing a door and a door frame comprising a panel and an edge material fitted to the end of the panel,
A decorative resin sheet having no adhesive layer on the back surface is attached to the panel via an adhesive, and a decorative sheet with an adhesive is attached to the edge member. manufacturing method.

In one embodiment, the decorative sheet to be attached to the panel and the adhesive-attached decorative sheet to be attached to the edge material are of the same color and pattern, and the adhesive applied to the panel is a PUR adhesive. It is considered a melt adhesive.

The door, door frame and manufacturing method thereof according to the present invention are as described above. Adopting a method of applying an adhesive with a high adhesive strength on the factory line and attaching it, there is no risk that the attached decorative sheet will shift over time and spoil the appearance, and a door and door frame that creates a sense of quality can be obtained. Also, there is an effect that the door and door frame can be manufactured with high quality and low cost.

1 is an exploded perspective view of the door and top of the door frame according to the present invention; FIG. FIG. 3 is a cross-sectional view of the face plate of the door and door frame panel according to the present invention;

BEST MODE FOR CARRYING OUT THE INVENTION Below, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. Since the door and door frame according to the present invention are mainly for toilet booths, the door and door frame of the toilet booth will be described in the following description. It has the same configuration.

FIG. 1 is an exploded perspective view of the top of a door 1 and a door frame 11 according to the present invention. As shown there, the door 1 consists of a panel 2 and an edge member 4 fitted to the butt end of the panel 2 via an aluminum receiving member 3. As shown in FIG. Similarly, the door frame 11 consists of a panel 12 and an edge material 14 fitted to the butt end of the panel 12 with an aluminum receiving material 13 interposed therebetween.

The panel 2 is composed of a frame member 5 , a core member such as a paper core placed inside the frame member 5 , and a surface plate 6 covering both sides of the frame member 5 . The surface plate 6 is, for example, a 4 mm-thick MDF (medium density fiberboard) 7 with a decorative sheet 8 attached to its surface and, if necessary, a moisture-proof sheet 9 attached to its back surface (Fig. 2). Generally, on the top surface of the panel 2, a hard vinyl chloride tape 10 of a similar color (single color) to the decorative sheet 8 is attached.

The decorative sheet 8 is printed with a variety of patterns such as a wood grain pattern and colored patterns. The decorative sheet 8 used does not have an adhesive layer on its back surface. The attachment of the decorative sheet 8 to the MDF 7 is performed in advance on the factory line, preferably using a PUR-based hot-melt adhesive. This adhesive has the advantage that it has a high adhesive strength, requires a small amount of application, and is resistant to deterioration over time. In the present invention, since the relatively inexpensive decorative sheet 8 having no pressure-sensitive adhesive layer on the back surface is adhered in advance to the MDF 7, which is a flat plate material, in the factory line, the operation of attaching the decorative sheet 8 is eliminated. It can be performed efficiently and at low cost.

On the other hand, for the edge material 4, which often has a curved cross-section to improve its appearance, "Dynoc Film" manufactured by 3M and "Belvian" manufactured by Takiron C.I. A decorative film 8a with an adhesive is used, the release paper on the back surface is peeled off, and the surface of the edge material 4 is adhered. In that case, both ends of the adhesive-attached decorative film 8a are wound inside the edge material 4. As shown in FIG.

Here, I will explain the difference between adhesives and pressure sensitive adhesives. The adhesive is liquid before use and becomes solid after being applied. However, since it takes time to harden, the progress of the hardening reaction depends on the adhesive strength. On the other hand, the adhesive always maintains a wet state (gel state) stably, and maintains that state even after being applied. Since the adhesive reaction is completed instantaneously, the attachment is completed in a short time, but the attachment strength does not increase beyond a certain level. In addition, because of the gel state, there is a problem in adhesive strength and holding power, and the adhesive may stretch over time, causing the adherend to gradually shift.

Since there is a difference between an adhesive and a pressure-sensitive adhesive, in the present invention, the decorative sheet 8 having no pressure-sensitive adhesive layer on the back surface of the panel 2 is adhered by a PUR-based hot-melt adhesive. By using a high-strength adhesive and adhering to the MDF 7 on the factory line, sufficient adhesive strength can be obtained. In the case of this configuration, the decorative sheet 8, which is the adherend, does not shift over time.

On the other hand, the adhesive-attached decorative film 8a is attached to the edge member 4 whose surface is not flat. The agent-attached decorative film 8a is strongly held between the aluminum receiving material 3 and prevented from slipping. As mentioned above, the adhesive reaction is completed instantly, so it can be applied at the construction site of the toilet booth. not suitable to do

The above is the description of the door 1, but the door frame 11, which consists of the panel 12 and the edge material 14 to be fitted to the edge of the door 1, has the same structure as the door 1 and is manufactured by the same method as the door 1. .

The door, door frame and manufacturing method thereof according to the present invention are as described above, and the panel does not use an expensive adhesive-attached decorative film and is a relatively inexpensive decorative sheet that does not have an adhesive layer on the back. However, since the adhesive with strong adhesive strength is applied on the factory line, there is no risk that the attached decorative sheet will shift over time and damage the appearance, and the door and door frame that exudes a sense of luxury. In addition, the door and door frame can be produced with high quality and low cost, and the industrial applicability is great.
