Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an artificial marble worktop in a system kitchen.

[0002]

2. Description of the Related Art As shown in FIGS. 4 to 6, a conventional worktop of this type has a frame member 21 made of wood fixed on the back surface of a top body 20 around adhesive openings 22 and 23 with an adhesive. In this case, the top body 20 is placed on the cabinet via the frame member 21 and is positioned and mounted with wood screws or the like.

[0003]

The problem lies in the separation and recovery of waste. Conventional worktop is top body 2
When the top body 20 is to be recycled, the frame material 21 has to be peeled off from the top body 20 because the 0 and the frame material 21 are made of wood and synthetic resin. Was overhanging. However, if synthetic resin molding is performed integrally with the frame member 21 on the back surface of the top main body 20 made of artificial marble, the manufacturing cost increases.

Accordingly, an object of the present invention is to obtain a work top made entirely of plastic, which can be obtained at the same manufacturing cost as using a wooden frame material as a backing material. In addition, an object of the present invention is to obtain an artificial marble wort top suitable for recycling.

[0005]

A worktop according to the present invention is a synthetic marble top body 2 made of synthetic resin.
And a top rib 2 formed of a different kind of synthetic resin material, and a group of back ribs 11 integrally bonded to the back surface of the top body 2 at appropriate intervals. The left and right horizontally long top body 2 is provided with an opening (3.4) for a water tank and / or a stove, and a group of back ribs 11 is disposed on the left and right around the opening (3.4). Have been. The top main body 2 is primarily molded with epoxy resin, and the back ribs 11 each having a linear shape can be secondary molded with the top main body 2 using vinyl ester resin or the like.

[0006]

When the top body 2 is placed and fixed on the cabinet in the same manner as the conventional wooden frame material, the back ribs 11 fill the space between the upper surface of the cabinet and the lower surface of the top body 2 to cover the cabinet. In addition to preventing the top main body 2 from being received in a one-sided state, it also functions to stop the top main body 2 from the cabinet.

The back rib 11 is integrally formed on the back surface of the top body 2 by secondary molding using a mold. Therefore, the back rib 11
The groups are formed in a line and connected in series so that the vinyl ester resin injected into the mold goes around the whole. Although the back rib 11 was considered to be formed of urethane resin for adhesion, the urethane resin hardened very quickly, so when trying to form a large number of back ribs 11, the back rib 11 was separated from the injection-side back rib formation portion. Urethane resin does not flow to the part where the back rib is formed. In addition, it has been found that when the back rib 11 is to be molded with a polyester resin, the adhesiveness is difficult. In this regard, the vinyl ester resin can secure the adhesiveness, and the curing time is not too short, and is excellent in molding workability.

[0008]

According to the worktop of the present invention, the top body 2 and the back ribs 11 integrated on the back side of the top body 2 are both made of a synthetic resin material. Can be reused. Although the artificial marble top body 2 is expensive in terms of material, a group of back ribs 11 for placing and fixing the top body on a cabinet and positioning and fixing it is sufficient if the function thereof is exhibited to the minimum necessary, and is inexpensive. Since a resin material can be used, the entire worktop can be manufactured at low cost. The top body 2 is primarily molded with epoxy resin, and the rear ribs 11 are secondarily molded while injecting a vinyl ester resin into the top body 2 using a mold. In addition, it was possible to obtain a material that can be integrally bonded with high adhesiveness and excellent workability.

[0009]

1 to 3 illustrate a worktop for a system kitchen according to the present invention. FIG. 1 shows a state in which the entire worktop 1 is viewed from the rear side. A left and right side of a horizontally long top main body 2 is provided with a water tank (sink) mounting opening 3 and a gas stove mounting opening 4 vertically. It is provided in a penetrating manner. In the figure, the peripheral portion 3a on the back surface side of the left mounting opening 3 is shown.
Urethane resin is injected into the water tank 5 to fix the upper end flange portion. Reference numeral 6 denotes an injection material of a urethane resin for fixing the water tank. Then, a gas stove (not shown) is dropped into the right attachment port 4 and attached.

On the back side of the top main body 2, a protruding edge portion 7 is formed to protrude from the front edge, left edge and rear edge on three sides. The protruding edge portion 7 has a front edge portion 7a protruding long downward. On the outer upper surface of the top body 2, a front edge 9 is formed with a small protruding height in a round shape and a rear edge 1 is formed.
0 is formed to protrude high so as to be in contact with the wall surface of the kitchen room.

The top body 2 is made of artificial marble molded of an epoxy resin, and on the back side of the top body 2, a number of back ribs 11 are provided around the openings 3 and 4 each consisting of a ridge. In FIG. 1, the stippled portion is the back rib 1.
It is one. The back rib 11 is made of a synthetic resin material that is less expensive than the molding resin material of the top main body 2 and has excellent adhesion to the top main body 2, for example, a vinyl ester resin. That is, a group of back ribs 11 is secondarily formed using a mold on the top main body 2 that has been previously formed in advance, and the group of back ribs 11 is integrally welded and fixed to the top main body 2. Therefore, each back rib 1
1 are all formed in a linear shape, a part of which is entirely connected, and the vinyl ester resin injected from at least one location flows into the entire formation portion of the back rib 11.

An arrangement of the back rib 11 will be described with reference to FIG. First, on the left outer side of the water tank attachment 3, a lateral rib 12 of the top main body 2 provided in the left-right direction inside the front edge portion 7 a of the protruding edge portion 7 of the top main body 2, Part 7b
Attach the vertical back rib 11a of 15mm left and right width
The rib 1 is provided in the vicinity of the left edge of the left side, and has a front-rear rib 20a having a front-rear width of 20 mm across the vertical rear rib 11a and the left edge 7c of the protruding edge 7.
5 are provided at equal intervals. A horizontal back rib 11c having a front-rear width of 20 mm is provided in the left-right direction so as to fill a space between the vicinity of the rear edge of the mounting opening 3 and the rear edge portion 7b of the protruding edge portion 7.

In the vicinity of the right edge of the water tank attachment 3 and the left edge of the gas stove attachment 4, a top body 2 provided in the left and right direction inside the front edge portion 7a of the protruding edge 7 is provided. The left and right vertical ribs 11d and 11e each having a width of 15 mm are arranged between the horizontal rib 13 on the side and the rear edge portion 7b of the protruding edge portion 7 in two directions.
Five horizontal back ribs 11f each having a width of 20 mm in the front-rear direction are provided at equal intervals between the two vertical back ribs 11d and 11e. The left and right ends of the horizontal back rib 11c on the rear side of the water tank attachment opening 3 are connected to the vertical back ribs 11a and 11d. In the drawing, reference numeral 14 denotes a front portion formed by injecting urethane resin provided in the left-right direction inside the front edge portion 7a.

Two right and left vertical back ribs 11g and 11h each having a width of 15 mm are provided in parallel on the right side edge of the gas stove opening 4 and the right side edge of the top main body 2 close thereto. And
At the front and rear edges of the attachment opening 4, horizontal back ribs 11i and 11j having a front and rear width of 15 mm are provided between both vertical back ribs 11e and 11g, and a horizontal back rib having a front and rear width of 20 mm is further provided between the preceding vertical back ribs 11g and 11h. Five back ribs 11k are provided at equal intervals. The back rib 11 group is arranged as described above,
Each is formed linearly, and all the back ribs 11 are connected at least in part to allow the vinyl ester resin injected into the mold to run around.

The protruding edge portion 7 on the back side of the top body 2 has a left edge portion 7c and a rear edge portion 7b, together with the other lateral ribs 12 and 13, having a projection height of 15 mm, except for a front edge portion 7a. The rear ribs 11 are also set to a projection height of 15 mm. The left and right vertical back ribs 11e and 11g and the front and rear horizontal back ribs 11i and 11j of the gas stove attachment opening 4 define a square edge of the attachment opening 4.

In this manner, the back rib 11 is attached to the top body 2.
Is integrally fixed to the upper surface of the cabinet via a back rib 11. For example,
A metal fitting is fixed on the upper surface of the cabinet, and the metal fitting is fitted between the back ribs 11 or the back rib 11 is fitted and engaged with the groove of the metal fitting, whereby the worktop 1 is positioned and fixed on the cabinet. The back rib 11 is disposed almost entirely on the back surface of the top body 2, and unlike the form in which the back surface of the top body 2 directly contacts the cabinet entirely, the lower end surface of the back rib 11 is placed on the cabinet. Since the top body 2 comes into contact with a small area, the top body 2 can be received so as to receive the load evenly over the entire surface without rattling the cabinet.

When the worktop 1 is separated from the cabinet at the time of waste collection and disposal, the worktop 1
Since both the top body 2 and the back ribs 11 are made of a synthetic resin material, there is no need for an operation of separating the two 2 and 11, and the two can be reused by being crushed and pelletized as they are.

As a worktop to which the present invention is applied, the attachment 3 for the water tank may be located on the right and the attachment 4 for the gas stove is located on the left, contrary to the illustrated example. Also,
A configuration having only the attachment port 3 for the water tank may be used. In that case, the rear rib 11 group may be provided on the left and right outer sides of the attachment port 3. Of course, there is also a form having only the gas stove opening 4. In this case, the rear rib 11 group may be provided on the left and right outer sides of the opening 4. In each of these embodiments, it is not always necessary to provide the back ribs 11 before and after the attachment port (3 and / or 4). It goes without saying that a part of the back rib group 11 may be provided in a lattice shape crossing vertically and horizontally as shown in FIG.

In the illustrated example, the back ribs 11a and 11b on the left side of the attachment opening 3 and the back ribs 11d, 11e and 11
f is communicated with the back rib 11c.
May be omitted, and the left and right back ribs may be separately formed of vinyl ester resin separately. When the resin injection points are provided at a plurality of positions, all the back ribs 11 are partially connected. You don't need to.
