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 movement systematically as a whole, to effectively use the space and to improve the function of the movement. 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 can be seen from the figure, the equipment for this three-dimensional door (e) is needed on the front of the drawer cabinet (ki) that is used by taking it in and out of the cabinet body (f), through the small item storage (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 edge 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 object, the method for manufacturing a three-dimensional door of the present invention configures the bent portion of the three-dimensional door and engages with the bent portion concave portions of the front and back flexible sheet attaching plates. Arrange a plurality of core materials corresponding to the shape of the three-dimensional door through a spacer having a protrusion,
It is characterized in that flexible sheet adhering plates are arranged on the upper and lower sides and press working is performed to laminate and integrate them.

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 according to the method of the present invention. As shown in FIG. 1, in the method of the present invention, the three-dimensional door (1) is composed of a plurality of members. That is, the three-dimensional door (1) includes a spacer (2) forming the bent portion and a plurality of core materials (3) (4) (5).
And the flexible sheet attaching plates (7) and (8) to which the flexible sheets (6) arranged above and below are attached.

The second one shows the manufacturing method of the present invention in more detail.
It is a figure and FIG.

FIG. 2 shows the positional relationship of members used in the method of the present invention at the stage of press working. A plurality of spacers (2) and cores (3), (4) and (5) are arranged corresponding to the shape of the three-dimensional door (1), and flexible sheet sticking plates (7) and (8) are arranged from above and below. Arrange and press die (9)
Pressurize in (10).

The core materials (3), (4) and (5) are preferably subjected to double-sided primer treatment. Further, an adhesive is applied to the inner adhesive surfaces of the flexible sheet attaching plates (7) and (8).

The conditions such as the pressure of the press work depend on the type of member used,
It can be appropriately selected depending on the required dimensions, strength and the like. For example, it is pressed at a pressure of 30 to 70 kg / cm ₂ for about 10 to 60 seconds.

As the spacer (2), as shown in an enlarged view in FIG. 2, it has a shape bent at an angle corresponding to the bent portion of the three-dimensional door, and as shown in FIG. It has a protrusion that engages with the bent concave portion of the attachment plates (7) and (8). More specifically, one protrusion (11) and two protrusions (12) (13) at the valley are provided on the top of the bent portion.
This spacer (2) can be carried.

These protrusions (11) (12) (13) are recesses (14) (15) (16) at the bent portions of the flexible sheet attaching plates (7) (8) which can be shown in FIG. 3, for example. ) Is firmly engaged. Therefore, the flexible sheet attaching plates (7) and (8) can be positioned.

As the flexible sheet (6), Japanese paper, vinyl chloride resin sheet, or any other suitable sheet can be used. It can be used for the purpose of protecting the surface of the three-dimensional door (1), moisture resistance, oil resistance and the like.

In the manufacturing method of the present invention as described above, the plurality of members forming the three-dimensional door are separated from each other with reference to FIGS.
Since it is not necessary to directly join by doweling as in the method shown in the figure, the adjustment of the gap at the joining portion and the accuracy are not affected at all.

By pressing the spacer (2), the core material (3) (4) (5), and the flexible sheet sticking plates (7) (8) which are set to a predetermined size and shape, the three-dimensional door can be accurately manufactured. Mass production of (1) is possible. Core material as a member (3)
Regarding (4) and (5) as well, unlike the conventional methods, it is not necessary to obliquely process the connecting edge. It is possible to realize a three-dimensional door with a high degree of processing that is free from the constraint of accuracy.

Of course, the present invention is not limited to the above examples. Various modes are possible for the specific shape of the spacer.

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