Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a furniture top plate, particularly a furniture top plate, in which a decorative board made of synthetic resin is laminated on the top surface of a wooden substrate, and a water tank is attached to the central opening. .

In recent years, the tops of furniture with water tanks, such as sinks and washstands, have been formed by laminating a synthetic resin decorative board on the top of a wooden substrate, with a metal water tank attached to the opening formed in the center. An integrated top plate that combines both has been proposed and put into practical use. Such a top plate is required to be able to easily connect the top plate and the water tank and to ensure watertightness at the joint, but conventional top plates of this type do not fully satisfy these requirements. There was nothing I could do.

The present invention aims to provide a method for manufacturing a top plate that fully satisfies these demands, and will be described in detail below with reference to the drawings. Referring to FIGS. 1 to 7, reference numeral 1 denotes a wooden board on which a decorative board 2 made of synthetic resin is laminated, and an opening 4 for mounting an aquarium 3 is formed at an appropriate center position. A groove 5 that opens inward is formed on the inner circumferential surface of 4 (FIG. 1). The wooden board 1 is made of plywood, particle board, etc. with a thickness of about 20 mm.
The decorative board 2 is made of a water-resistant synthetic resin board such as melamine resin. A backer 1a is bonded to the back surface of the wooden substrate 1, if necessary, to prevent warping due to lamination of the decorative board 2.

As shown in FIG. 1, after forming an opening 4 and a groove 5 in a wooden substrate 1, the opening 4 is closed and a decorative board 2 is bonded and laminated on the upper surface of the wooden substrate 1 (second
figure). Separately from the process shown in FIG.
(Figure 3). The thickness of the spacer is 1
mm or more is preferable, and the water tank 3 is placed on the top surface of the flange portion 3a.
It is arranged in an annular shape so as to surround the or,
A mold release agent is applied to the outer peripheral surface 6a as necessary.

Next, as shown in FIGS. 4 and 5, a spacer 6 is brought into contact with the lower surface of the decorative board 2 that is laminated on the wooden substrate 1 and closes the opening 4, and the spacer 6 is brought into contact with the inner peripheral surface of the opening 4 and the aquarium 3.
A bonding material 7 made of synthetic resin is filled into the gap with the outer circumferential surface of the water tank 3 and the opening 4 of the wooden substrate 1 is filled and cured.
to be bonded to the inner circumferential surface of the At this time, since a predetermined gap is secured between the flange part 3a of the aquarium 3 and the decorative board 2 by the spacer 6, the bonding material 7 is also filled in this gap, and the flange part 3a and the decorative board 2 are filled with the bonding material 7. The plates 2 are reliably joined. Holes 3b are formed at appropriate intervals in the flange portion 3a in order to improve the injection of the synthetic resin into the gap and to strengthen the bond between the bonding material 7 and the flange portion 3a.
As the bonding material 7, a thermosetting synthetic resin such as epoxy resin, urethane resin, or polyester resin is suitable.
As shown in Figure 5, it will be possible to perform the pouring work easily by turning the wooden board 1 upside down with the decorative board 2 facing down and placing the spacer-equipped water tank 3 on the wooden board 1. . Further, it may be preferable to apply a primer to the outer surface of the water tank 3 to be bonded to the bonding material 7, if necessary.

After joining the water tank 3 to the inner peripheral surface of the opening 4 and the decorative board 2 with the joining material 7 as shown in FIGS. 4 and 5,
As shown in FIG. 6, a V-shaped groove 8 is cut at the boundary between the spacer 6 and the bonding material 7 using a router.
Remove spacer 6. As a result, a part of the decorative board 2 blocking the opening 4 is removed at the same time, and the upper part of the water tank 3 is opened. (Figure 7). In this way, since the flange portion 3a of the water tank 3 is located one step lower than the top surface of the decorative board 2, drainage can be improved, and since the bonding material 7 has entered into the groove 5 on the inner circumferential surface of the opening 4. , the bonding state between the bonding material 7 and the wooden substrate 1 becomes extremely strong. still,
Instead of such a groove 5, the portion indicated by the dotted line in FIG. 6 may be cut out to form a stepped portion.

8 to 14 show that in order to strengthen the connection between the wooden substrate 1 and the water tank 3, a joining plate 10 is attached to the flange 3a of the water tank 3 so as to be able to move in and out from the side. Groove 5 on the inner peripheral surface of opening 4 at the tip
The other points are the same as those shown in FIGS. 1 to 7 above. A reinforcing frame 9 is attached to the bottom of the top plate over the wooden board 1 and the bonding material 7, and is used as reinforcement is required.

In the case shown in FIGS. 8 and 9, the connecting plate 10 is connected to the elongated hole 1.
1 and a pin 12 that engages in the elongated hole so that it can be moved in and out by sliding it laterally, and the one shown in FIGS.
0' is rotatably attached to the flange portion 3a by a shaft 13, so that it can be freely moved in and out from the side.
Then, as shown in FIG. 12, the bonding board 10 is inserted into the groove 5 of the wooden substrate 1, and the bonding material 7 is filled and cured, and then grooved with a router (see FIG. 13). ), remove a part of the decorative board 2 that closes the opening 4 and the spacer 6 (FIG. 14).

As described above, according to the method for manufacturing a furniture top plate of the present invention, a water tank can be firmly and reliably attached to a top plate made of a wooden substrate laminated with a decorative board, and the watertight state of the joint can be maintained. This can be done more reliably, and the water tank can be placed one step below the top surface of the top plate, allowing for better drainage. Furthermore, since the injection space for the bonding material is limited by the inner circumferential surface of the opening of the wooden substrate, the decorative board, the outer circumferential surface of the water tank, and the spacer, there is an advantage that a mold required for injecting the synthetic resin is not required.
