Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a cabinet, in which concave portions and convex portions are formed on each board, this is placed on a jig, and a decorative film is closely attached to this surface to form concave portions and convex portions. The object of the present invention is to provide a method for easily manufacturing a cabinet using only general-purpose machines such as woodworking machines and vacuum forming machines.

As an example of a conventional method for manufacturing cabinets such as television receivers and speaker boxes, the so-called U-cut method is a method that uses lauan plywood with a decorative film 1 attached to the surface, as shown in Fig. 1. Cut U-shaped grooves 4 at four locations on the back surface of 2 using a U-shaped groove cutting tool (U-cut machine) 3, and then bend the U-shaped grooves 4 inward, as shown in Figure 2. As shown, a top plate 2a and side plates 2b and 2c are constructed, a core 5 is fitted into the U-shaped groove 4 and bonded together, and finally a base plate 6 is bonded to the side plates 2b and 2c.

However, this method requires a special instrument 3 called a U-cut machine to form the U-shaped groove 4;
It cannot be manufactured cheaply, and when bending is taken into account, the thickness a of the bottom of the U-shaped groove 4 must be approximately 0.2 nm, which may result in processing defects. In addition, since the thickness a of the U-shaped groove 4 is relatively small, it is difficult to form a corner part with an accurate shape when bent, which causes problems in appearance. It is difficult to form with a radius of 10 degrees or less, and furthermore, it requires a large number of man-hours to fit and bond the cores 5 one by one into the U-shaped grooves 4, which also has the disadvantage that it cannot be manufactured at a low cost. there were.

The present invention eliminates the above-mentioned drawbacks, and each embodiment thereof will be described with reference to FIG. 3 and subsequent figures.

During manufacturing, as shown in FIG. 3, a top plate 7, side plates 8 and 9, and a base plate 10 made of shrinkable plates are prepared, and grooves 7 a t 7 b are formed on the back side of the opposing sides of the top plate 7. and curved surfaces 7c and 7d are formed on both sides of the surface,
A concave groove 7a of the top plate 7 is provided on one side of the side plates 8 and 9.

7b, and grooves 8b and 9b are formed on the back side of the other side, and curved surfaces 8c and 9c are formed on the front side of the other side. Convex portions 10a and 10b of a size that can fit into the grooves 8b+9b of the side plates 8 and 9 are formed on opposing sides.

These processes can be easily performed with common woodworking machines, and can be manufactured more easily and at a lower cost than the conventional U-cut method using a special U-cut machine.

Next, as shown in FIG. 4, the top plate 7 is placed in the center on a convex jig 11 formed to correspond to the size of the top plate 7 and the side plates 8, 9, and the top plate 7 is placed on both sides of the convex jig 11. ridge line 7' on both sides and side plates 8, 9
Side plates 8, 9 so that the ridge lines 8', 9' of one side are in contact with each other.
, and position the top plate I and side plates 8 and 9, respectively.
A suitable adhesive is applied to the surfaces of the top plate 7 and side plates 8 and 9 by spraying.

On the other hand, a decorative film 12 made of vinyl chloride or DAP laminate or the like with a size corresponding to the size of the top plate T and side plates 8 and 9 and having wood grain printed on its surface is prepared, and an adhesive is sprayed on the back surface of the decorative film 12. is applied and placed on top plate 7 and side plate 8.9.

When this state is placed in a vacuum forming machine using rubber or the like as a medium and heated under vacuum, the decorative film 12 is brought into close contact with the surfaces of the top plate 7 and side plates 8 and 9 by heating and suction.

After that, the jig 11 with each plate placed thereon is taken out from the vacuum forming machine, and the jig 11 is removed from each plate.
As shown in FIG. 5, top plates 7 whose surfaces are covered with a decorative film 12 and which are connected to each other by the decorative film 12
, side plates 8 and 9 are obtained.

This vacuum forming machine is a general-purpose machine, and is easier to obtain than the U-cut machine used in the conventional U-cut construction method, and from this point of view, it can be manufactured at a lower cost.

Next, adhesive is applied to the grooves 7 a t 7 b of the top plate 7 and the grooves Bb and gb of the side plates 8 and 9, and the ridge line 7' of the top plate 7 is
Bend the parts and attach the side plates 8 to the concave grooves 7a and 7b of the top plate 7.
The convex parts 8a and 9a of the main plate 10 are fitted and adhesively bonded to make the whole into a U-shape as shown in FIG. Then, the cabinet is completed.

As another method, as shown in Fig. 7, the side plate 8, top plate 7, side plate 9, and base plate 10 are placed on a jig (not shown) in this order from the left end, and the sizes of these are placed on the jig (not shown). A decorative film 12' corresponding to the above is placed, and placed in a vacuum forming machine in the same manner as in the above embodiment, the film 12' is brought into close contact with the surfaces of the top plate 7, side plates 8, 9, and base plate 10. The shape shown in FIG. 6 may be obtained by applying an adhesive to the surface, bending it, and fitting and bonding the convex portion into the groove.

Note that the ends of the top plate 7 and side plates 8 and 9 do not necessarily have curved surfaces 7c.
, 7d, 8c, and 9c are not necessary, and may remain in a right-angled shape.

As mentioned above, the method for manufacturing a cabinet according to the present invention includes:
A concave portion and a convex portion that can fit into each other are formed on one side of the opposing sides of each plate that takes over the cabinet, so that when one of the plates is bent, the concave portion and the convex portion fit into each other. The opposite sides of each board are brought together and placed on a jig to position them, and a decorative film is placed on top of this using an adhesive, and the decorative film is applied to the surface of each board. Since the cabinet is formed by closely fitting each board, bending the sides of each board, and fitting the concave and convex parts to each other, the concave and convex parts of each board can be easily processed using ordinary woodworking machines. In addition, since the vacuum forming machine that brings the film into close contact is a very common general-purpose machine, it can be manufactured at a lower cost than the conventional so-called U-cut method, and it can also form thinner parts unlike the U-cut method. There is no risk of machining defects because it is not necessary, and since the thin wall part is not bent as in the U-cut method when obtaining the corner part, an accurate corner shape can be obtained when bending. It is possible,
Furthermore, when forming a corner into a curved surface, there is no restriction by equipment as in the U-cut method, and since the curved surface is simply processed with a woodworking machine, the corner can be formed with any radius. Unlike the cutting method, there is no need to fit and glue the cores one by one inside the curved surface after bending, and simply fit and glue the concave part and the convex part, so it can be manufactured without using any man-hours. Also from this point of view, it has the advantage of being able to be manufactured at low cost.
