Abstract

PURPOSE: To improve productivity of a draining plate in a manner such after a plate main body is housed in a predetermined position in a mold, a decorative peripheral member and a projection are formed by pouring a synthetic resin fluid into a cavity, so that a work of attaching the decorative peripheral member and the projection by screws or the like is unnecessary. CONSTITUTION: In a draining plate for a sink, a decorative periphery member 4 made of a synthetic resin is attached along the periphery of a metal plate main body 2 and projections 5 and 5 are provided in a line in facing front/rear positions with respect to the plate main body 2. In the plate main body 2, a number of drain holes are formed and a lowered periphery 12 is formed along the periphery of a portion 8 on which goods are put and which has a descending inclined portion 10 toward the outside. When such a draining plate is manufactured, the plate main body 2 is housed in a lower-half mold 19 of a mold 18 in an upside-down manner. After that, an upper-half mold 20 is put and a synthetic resin fluid is poured into a space 21 corresponding to the decorative periphery member 4 and the projections 5. The synthetic resin fluid is poured into a through hole of the decorative periphery member 4 so as to cover a folded edge of the plate main body 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain board for a sink, which is placed on the front and rear edges of a water tank of a sink so as to straddle the water tank.

[0002]

2. Description of the Related Art Conventionally, the following types of drainage plates for sinks have been known. That is, there is known one having a plate-shaped main body and a pair of front and rear projecting protrusions made of synthetic resin fixed to the front and rear edges of the plate-shaped main body with screws. By placing the front and rear overhanging projections on the front and rear edges of the water tank of the sink, the draining plate for the sink is placed on the top of the sink so as to be slidable left and right so as to straddle the water tank. Is.

[0003]

DISCLOSURE OF THE PRIOR ART The conventional draining plate for a sink has the following defects. That is, since the pair of front and rear projecting protrusions are fixed to the front and rear edges of the plate-shaped main body with screws, the screwing work is troublesome, resulting in poor productivity,
Moreover, there is a drawback that the cost is high.

[0004]

[Means for Solving the Disadvantages] The present invention employs the following means in order to eliminate the above disadvantages. The present invention
A plate-shaped main body, a synthetic resin decorative edge member provided on the peripheral edge of the plate-shaped main body, and a pair of projecting protruding pieces that are continuously provided at portions of the decorative edge member that face each other across the plate-shaped main body. The plate-shaped main body has an article placing portion, a hanging edge formed at the periphery of the article placing portion in a hanging shape and having at least one through hole, and a hanging edge of the hanging edge. It has a folded edge continuously provided at the lower end of the required part, and the decorative edge material is configured to cover the hanging edge from below, and the decorative edge material and the overhanging projecting piece form them. After the plate-shaped main body is housed in a predetermined position in the mold, the synthetic resin fluid is poured into a space corresponding to the decorative edge member and the protruding protrusion of the molding die.

[0005]

The present invention has the following functions. Since it is not necessary to fix the decorative edge member and the projecting protruding piece to the plate-shaped body with a screw or the like, productivity can be improved and cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments with reference to the drawings. In this specification, the front means the lower side of FIG. 1, the rear means the upper side of FIG. 1, and the left means the left side of FIG.
Right means the right side of the figure.

The draining plate 1 for the sink is a plate-shaped main body 2 made of metal such as stainless steel, and a decorative edge member 4 made of synthetic resin such as polypropylene / ABS resin provided on the periphery of the plate-shaped main body 2. The decorative edge member 4 has a pair of front and rear projecting protrusions 5 that are continuously provided in front and rear portions of the decorative edge member 4 that face each other across the plate-shaped body 2.

The plate-shaped main body 2 is a planar rectangular shape having four curved corners each having an arc of a quarter. The plate-shaped body 2
Is an article mounting portion 8 having a large number of drain holes 9 and an inclined portion 10 which is inclined downward toward the outside, and a hanging edge 12 formed in a pendant shape on the peripheral portion of the article mounting portion 8. Have The hanging edge 12 includes left and right edge portions 12a and front and rear edge portions 12a.
It has b and a curved edge 12c (see FIG. 5). The folded edge 13 is continuously provided upward only at the lower ends of the left and right edges 12a (long edges). In addition, both left and right edges 1
Through holes 14 are formed in the front and rear portions of 2a. That is,
A total of four through holes 14 are formed in the left and right edge portions 12a. The curved edge portion 12c is shorter than the lengths of the left and right edge portions 12a and the front and rear edge portions 12b (see FIG. 5). The lengths of the left and right edge portions 12a and the lengths of the front and rear edge portions 12b are equal.

The decorative edge member 4 covers the hanging edge 12 from below. Further, the front and rear portions of the decorative edge member 4 cover the inclined portion 10. Overhanging protrusion 5
Reinforcing ribs 15 are formed on the lower surface of the sheet at predetermined intervals in the left-right direction. The decorative edge member 4 and the overhanging protruding piece 5 are molded as follows. That is, as shown in FIGS. 6 and 7, after the plate-shaped main body 2 is placed upside down in the lower mold 19 of the molding mold 18 and stored at a predetermined position, the lower mold 19 is covered with the upper mold 20 and the decorative edge member 4 is formed. Further, the synthetic resin fluid is poured into the space 21 corresponding to the projecting protruding piece 5, and is cured and demolded. As is clear from this description, the synthetic resin fluid enters the through hole 14 and hardens, and also hardens so as to wrap around the folded edge 13. As a result, the synthetic resin that has entered the through hole 14 and hardened and the folded edge 13 act as a stopper for the decorative edge member 4.

[0010]

[Modifications, etc.] Modifications will be described below. (1) The hanging edges 12 may all have the same length. (2) The folded edge 13 may be formed on at least one of the front and rear edges 12b and the curved edge 12c. (3) The plate-shaped body 2 may be made of artificial marble or the like instead of being made of metal.

[0011]

The present invention has the following effects due to the above-described structure. According to the invention of claim 1, since it is not necessary to fix the decorative edge member and the projecting protruding piece to the plate-shaped main body with screws or the like,
The productivity can be improved and the cost can be reduced. According to the first aspect of the present invention, the synthetic resin that has entered the through hole and hardened and the folded edge act as a retaining member, so that the decorative edge member can be firmly fixed to the plate-shaped body. According to the invention of claim 1, since the folded edge functions as a reinforcing edge, the drain board for the sink can be made durable. According to the invention of claim 2, since the hanging parts of the curved portions at the four corners are made shorter than the hanging parts of the other parts, it is possible to suppress wrinkling of the hanging parts during bending of the hanging parts as much as possible.
