Description

The present invention relates to a structure of a top part of a top plate, which is mainly used in a system kitchen.

Conventionally, as shown in FIG. 7 and FIG. 8, as a material of the kitchen top plate, there is one in which a particle board (31, 33) is used as a core and a decorative board (32, 34) such as melamine resin is attached to the surface. (For example, refer to Patent Documents 1 and 2).

Conventionally, in a plate material in which a particle board is used as a core material and a decorative plate is provided on the surface, there is a structure that prevents the core material from penetrating water into the particle board. In this known plate material, a sealing material that hermetically shields the fine gap is provided at a position directly below the joint between the surface (upper layer) and the edge material to prevent water permeation (see Patent Document 3).

Particleboard is excellent in workability and light weight, but has high water absorption. Melamine resins are excellent in impact resistance, heat resistance, water resistance, and wear resistance. Therefore, a kitchen top plate is often used in which a particle board is used as a core material and a decorative plate such as a melamine resin is attached to the outer surface. The thickness of the melamine resin decorative board in this case is 0.8 mm to 1.2 mm.

Such a kitchen top plate does not break under normal stimulation, but when concentrated stress is applied, for example, when a sharp substance collides with the outer peripheral side edge surface, it breaks and is partially missing or surface May be deformed or scratched. As a result, the particle board was exposed and absorbed, thereby causing the top plate to rot, the surface decorative plate to peel off due to swelling, warping, and cracking. When such a failure occurs, it is difficult to repair, so to regain the beauty and function of the kitchen, the entire top plate had to be replaced.

In Claim 1, it is a board | plate material used for a top plate, Comprising: It has the same cross section as a panel-shaped core material and the core of the said core material, is affixed on the said tree mouth, and extends in the plane direction of the said core material, The said core material A reinforcing material having impact resistance that constitutes the outer edge, a top decorative plate having impact resistance that covers the front surface of the core material and the end of the outer edge of the core material, and the reinforcing material. The problem is solved by a plate material comprising a side decorative plate having impact resistance that covers the side surface of the outer edge to be formed.

Since the portion of the top plate that should be reinforced most is the outer edge portion, only the portion extending in the plane direction of the core material is sufficient for providing the reinforcing material. As the core material, a material that can be easily molded, such as particle board, plywood, or synthetic resin plate, is used. As the reinforcing material, a material having impact resistance such as melamine resin is used. A thermoplastic resin plate material (polyester, polystyrene, etc.), a thermosetting resin plate material (phenol resin, etc.), or a metal plate such as aluminum or stainless steel can be used for the top decorative plate and the side decorative plate.

In Claim 2, it is a board | plate material used for a top plate, Comprising: It has the same cross section as the core of a particle board, and the core of the said core, It is affixed on the said neck and extends in the plane direction of the said core, and the said core Reinforcing material having impact resistance constituting the outer edge of the material, top decorative plate having impact resistance covering the front surface of the core material and the end of the outer edge of the core material, and the reinforcing material A side decorative plate with impact resistance that covers the side surface of the outer edge formed by the reinforcing member, and the reinforcing member and the top decorative plate and the side decorative plate are plate members made of a melamine resin plate. The problem is solved by a plate material having a length of 7.5 mm or less extending in the plane direction.

When the core material is a particle board, the reinforcing material is a melamine resin plate, and the top decorative plate and the side decorative plate are melamine resin plates, the reinforcing material functions sufficiently if provided for a length of 7.5 mm.

The reinforcing material may be configured to extend 3 mm in the planar direction of the core material. Three 1 mm reinforcing plates may be used to make 3 mm, one 1.5 mm reinforcing material may be used, or one 3 mm reinforcing material may be used. If the number of melamine resin plates is reduced, the production process can be reduced because one bonding step is reduced. Since a melamine resin plate having a thickness of 1.5 mm is currently most popular, inexpensive and easily available, the use of this material has the effect of being easy to manufacture and reducing manufacturing costs.

A decorative board can also be set as the structure affixed on the surface of a core material, a reinforcing material, and the back surface of a core material by roll forming. By sticking by roll forming, a decorative sheet having water resistance can be stuck to the outermost layer without any gap, and there is no risk of moisture absorption into the inner layer.

A very simple structure in which a reinforcing plate is provided only on the outer edge side wall between the core material and the outer decorative plate greatly improves impact resistance, breaks the top plate, and absorbs water, such as particle board. Accidents such as material swelling, decay, peeling of the decorative board and core can be prevented.

Even when the outermost melamine resin plate of the top plate is scratched, the interior of the melamine resin plate with excellent water resistance prevents water from entering the damaged part and allows moisture to reach the particle board. Absent.

[Example 1]
The target of Example 1 is the top plate of the kitchen stand of the system kitchen. Examples thereof are A, B, and C surrounded by broken lines in FIG. As shown in FIGS. 1 and 2, the top plate (7) is affixed with two reinforcing members (2, 3) made of a melamine resin plate overlapped on the end portion of the core material (1) made of particle board. Each of the two melamine resin plates has a thickness of 1.5 mm, and the total thickness becomes 3 mm by stacking the two sheets. A side edge face decorative board (5) made of a melamine resin decorative board is attached to the outside of the reinforcing members (2, 3).

The melamine resin plate is used as the reinforcing member because the melamine resin plate has impact resistance. The reason why two sheets of 1.5 mm are used is that a melamine resin plate having a thickness of 1.5 mm is currently the most readily available and cheap in the market. A synthetic rubber adhesive is used for bonding. The adhesive strength can be improved by roughening the adhesive surface of the melamine resin plate with sandpaper or the like in advance.

[Example 2]
The object of the second embodiment is also the top plate of the kitchen stand of the system kitchen as in the first embodiment, and has a structure in which the shape of the lip portion is rounded. The top plate (15) of Example 2 is shown in FIG.3 and FIG.4. The core material (11) made of particle board is processed into a desired shape. A notch (16) corresponding to the thickness of the reinforcing plate (12) is provided in the upper part of the core material (11). The reinforcing member (12) is made of melamine resin. The reinforcing plate (12) is bonded by roll forming from the notch (16) to the bottom surface of the end. The reinforcing member (14) is bonded to the outer periphery of the core member (11) and the reinforcing member (12) by roll forming as in the conventional case. In the case where the shape of the end portion is rounded, the effect of reducing one production process is great, and therefore there is only one melamine resin plate as a reinforcing member. The thickness of the melamine resin plate is determined according to the required impact resistance.

With reference to FIG. 5, the top plate according to the present invention is incorporated in the system kitchen such as the top plate of the kitchen table (20), the top plate of the dining table (21), the top plate of the storage shelf counter (23), and the like. It can be used for the top plate of various furniture. Using a common top plate in one system kitchen is extremely effective in unifying the design of the system kitchen.

The melamine resin decorative board is widely used for the top plate of the kitchen table because it has water resistance and heat resistance. However, the case where it uses as a top plate, such as a dining table and a storage shelf counter, was not assumed. For this reason, when the user selects furniture for dining, a material different from that for the kitchen has to be used, and there has been a restriction on unification in design. However, in recent years, the number of cases in which a kitchen is installed in the center as a part of a living-dining space is increasing, and there is a high demand for unifying the design of dining furniture arranged in the kitchen and its surroundings.

As shown in FIG. 5, the top plate according to the present invention is used not only for the kitchen table (20) but also for dining furniture such as the dining table (21), and further, the thickness of the top plate and the decorative material for the mouthpiece. By making the same as the kitchen stand, it is possible to give a unified design as a whole.

Furthermore, by using the top plate according to the present invention for the bathroom vanity, toilet counter, living furniture top plate, waist wall top plate, lower leg storage top plate, etc., the entire furniture in the house can be used as dining furniture. It becomes easy to make a unified design.

When the top plate according to the present invention is used for a dining table, an IH heater (25) can be incorporated in the dining table (21) as shown in FIGS. Conventionally, each time a food is heated or kept warm by a dining table, a table type gas stove or a plate heater that takes electricity from an indoor outlet is prepared and used for the table. The problem with gas stoves is that they cause indoor air to become dirty. In addition, the plate heater had to be powered from the wall outlet of the room, and the cords crawled from the table to the wall surface. Further, the gas stove and the plate heater need a storage place when not in use.

Therefore, a hole is made in the top plate (21) of the dining table, and a built-in type IH cooking heater is incorporated into the aggregate (24) on the back side of the top plate and attached to the dining table. In order to prevent the power cord from being exposed, a wiring path is provided in the dedicated cabinet under the table, and an AC 100V outlet is provided in the dedicated cabinet portion so as to secure a power source for the electrical appliances used on the dining table. Thereby, heating and heat insulation of a foodstuff can be easily performed on a dining table.
