Description

TECHNICAL FIELD The present invention relates to a method for manufacturing a three-dimensional door.
More specifically, the present invention relates to a method for manufacturing a three-dimensional door that is easy to process and has good accuracy and that is suitable for mass production.

(Background Art) In recent years, with the increasing demand for higher functionality of housing equipment, from the viewpoint of efficient use of living space and convenience of operation, design and construction that do not care about the layout and shape of conventional equipment. Is beginning to spread.

For example, as shown in FIG. 4, in the system kitchen equipment, a part of the counter (a) is projected to functionally use the cooker (a), and the storage section under the counter (a) is also used. Attempts have been made to use it efficiently.

Such an attempt is to grasp the user's movements in a systematic manner, to effectively use the space and to improve the efficiency of movements, so that the protrusion (U) on the counter (A), which has not been considered so far, can be considered. The formation of () has cast a ripple on the future design of the kitchen and the ideal way of housing equipment.

However, there are some problems left to be solved concretely in such an equipment having an irregular shape. One of them is the problem of how to manufacture an oddly shaped three-dimensional door.

In the system kitchen of FIG. 4, for example, by forming the protruding portion (C) on the counter (A), it becomes possible to use the storage space at the corner portion together with the storage unit provided with the flat door (D). For this purpose, it becomes necessary to provide a three-dimensional three-dimensional door (e) at the corner. Fifth corner storage space is shown as a cabinet unit
As is clear from the figure, it is necessary to install this three-dimensional door (e) on the front of the drawer cabinet (ki) that is used by putting it in and out of the cabinet body (f) via the accessory storage part (ku). .

Until now, this three-dimensional door (e) is shown in Figs.
As shown in the figure, each member of the left horizontal portion (K), the inclined portion (K) and the right horizontal portion (S) was joined by doweling and mortaring.

However, depending on such a manufacturing method up to now, there is a problem that it is difficult to adjust a gap at a joint portion of each member (K), (K), and (C), and accuracy is not obtained. At the same time, at the time of this joining, as is clear from FIG. 7, at the joining portions (A) and (B), each member (K) (K)
Although it is necessary to obliquely process the edges of (S), it is difficult to improve the accuracy of this processing. For these reasons, it has been difficult to mass-produce the three-dimensional door (e) by the conventional methods.

Therefore, in order to cope with the future increase in demand, it is absolutely necessary to realize a highly accurate mass production method for this three-dimensional door.

(Object of the Invention) The present invention has been made in view of the circumstances as described above, overcomes the drawbacks of the conventional manufacturing method, is easy to process and highly accurate, and is suitable for mass production. It is an object of the present invention to provide a method for manufacturing a three-dimensional door that has been manufactured.

DISCLOSURE OF THE INVENTION In order to achieve the above-mentioned object, the method for manufacturing a three-dimensional door of the present invention has a structure in which a plurality of plate bodies that form a three-dimensional door are separated from each other at their joints at opposite edges. As shown in the figure, it is placed at a predetermined position on the mold surface corresponding to the door shape provided in the press mold, and then resin is injected between the edges facing the plates to perform press molding, and the plates are joined together by this resin. In addition, the corners formed from only the resin are formed at the joints to manufacture a three-dimensional door.

The manufacturing method of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an example of a three-dimensional door plate manufactured by the manufacturing method of the present invention. As is clear from FIG. 1, in the method of the present invention, a plurality of plate bodies (2) constituting a three-dimensional door, that is, a three-dimensional door (1).
(3) and (4) are joined by the resin (5) at the connection edge. The respective plate bodies (2), (3) and (4) do not have their joint edges directly interconnected at the joint, as shown in FIGS. 6 and 7, for example. Therefore, there is no need to worry about the adjustment and accuracy of the gap at the joint portion, unlike the case of the conventional doweling method.

One of the features of the manufacturing method of the present invention is that the three-dimensional door (1) is manufactured in a press mold. That is, in the present invention, as shown in FIG.
A plurality of plate bodies (2), (3) and (4) are pressed by a press die (6) so that connecting edges facing each other at a joint are separated from each other.
It is placed at a predetermined position on the mold surface provided in (7). The mold surface is formed in a shape corresponding to the door shape, and the plate body (2) (3)
As a result, (4) will be arranged on mutually different surfaces. Next, the resin (5) is injected between the opposed edges of the plate bodies (2), (3) and (4), and press molding is performed.

Here, as the press die, a silicone rubber die can be exemplified as a preferable one. As the resin used for joining, an appropriate adhesive synthetic resin, for example, an appropriate thermosetting resin such as urethane resin or acrylic resin can be used. Urethane resin can be illustrated as a preferable example.

As the plurality of plates (2), (3) and (4), not only wood plates but also decorative materials may be used. Furthermore, ceramics, metals, synthetic resins, and composite materials of these may be used. May be.

FIG. 3 shows the above method of the present invention in series. As shown in FIG. 3, in this method, first, (a) and (b): the plate body (8) is processed into a desired size by cutting or the like by a usual method, and a plurality of plate bodies (2) are processed.
(3) Obtain (4). At this time, the diagonal processing at the connection edge, which is indispensable in the conventional methods, is not necessary at all. Next, (b) and (c): this plurality of plate bodies (2)
(3) and (4) are joined by the resin (5).

At this time, a corner formed of only resin is formed in the joint by press molding as shown in FIG. Therefore, the corners of the three-dimensional door can be easily formed into various shapes including the curved surface R processing, and
Excellent processing accuracy. Further, the corners are effectively prevented from being damaged or broken.

Of course, the method for manufacturing a three-dimensional door of the present invention is not limited to the above example, and for example, it is possible to easily manufacture a door having a more complicated three-dimensional shape, and a three-dimensional door with a high degree of processing can be mass-produced. Can be manufactured by.

(Effects of the Invention) As described in detail above, according to the present invention, a three-dimensional door can be formed with high accuracy by press molding without being restricted by the processing accuracy at the joint unlike the conventional methods, and by a mass production process. It becomes possible to manufacture.
