Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a back guard shelf for a sink that projects from the front of the back guard of the sink.

(Prior Art and its Problems) Examples of conventional back guard shelves for sinks include those shown in FIGS. 4 to 6, for example. In the figure, 1 is the top plate of a stainless steel sink, and 1a is its back guard.

In the device shown in FIG. 4, sheet metal hook fittings 2 as shown in detail in FIG. 4b are attached to two places on the back guard 1a as shown in FIG. Hook fittings 2
Hook portion 4a of a flat shelf 4 made of wire material as shown in the figure.
The shelf 4 is attached to the back guard 1a by hooking it.

However, since the one shown in Fig. 4 is made of sheet metal, it is easy to get your hand caught on the protrusion, and the shelf 4 is easy to come off, and since the shelf 4 is flat, there are problems in that objects placed on it tend to fall. be.

In addition, as shown in FIG. 5 b and c, protrusions 5 b are provided on both sides of the central shaft portion 5 a that protrudes from the back surface of the round bar-shaped hook 5, and
A long hole 1b made in the back guard 1a as shown in
After inserting the hook 5 into the back guard 1a, the hook 5 is fixed to the back guard 1a by rotating it 90 degrees. The raised curved portion 6a is engaged.

However, although the one shown in FIG. 5 is easy to install, there are problems in that the central shaft portion 5a is structurally thin and easily breaks, and since the shelf 6 is flat, items placed on it are likely to fall.

In addition, in the case shown in FIG. 6, hook fittings 7 made of sheet metal as shown in detail in FIG. As shown, the hook portion 9a of a flat shelf 9 made of wire rod is hooked to attach the shelf 9 to the back guard 1a.

However, the device shown in FIG. 6 has the problem that the shelves 9 are easy to come off, and because the shelves 9 are flat, objects placed on them are likely to fall.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, the top surface is open and four of the transverse wire rods of the wire back guard shelf having rising edges on the four circumferences are removed from the rear. It extends over the edge and forms two chevron-shaped bent parts, and provides screw holes in the back guard of the sink corresponding to these two bent parts, respectively.
A hook having a screw insertion hole in the center and an annular groove on the outer periphery is fixed to the back guard by screwing a tassel pin screw inserted into the screw insertion hole into the screw hole, and attaching the bent portion to these two hooks. A back guard shelf for a sink is constructed by attaching the back guard shelf to the sink by engaging the two.

(Function) As mentioned above, in the present invention, the back guard shelf is made of wire material and the upper surface is open, and
Since it is constructed in the shape of a basket with rising edges on all four sides, there is no risk of items placed on the shelf falling off.

In addition, each back guard of the sink is provided with a screw pilot hole, and a hook with a screw insertion hole in the center and an annular groove on the outer periphery is inserted into the hook, and a tassel pin screw inserted into the screw insertion hole is screwed into the screw pilot hole. Since the back guard shelf is attached to the sink by engaging the bent portions formed integrally with the back guard shelf with the hooks fixed at two places on the back guard, installation is easy, and The engagement between the hook and the back guard shelf is also reliable, eliminating the risk of the hook falling off.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, 1 is the top plate of the sink, and 1a is a back guard integrally formed on the rear edge.

In this embodiment, a wire rod 10 such as a stainless steel wire is used as a material, and the upper surface is open, and
A basket-shaped back guard shelf 11 having rising edges on all four sides is formed. 10a is the upper edge wire of the rising edge formed around the four circumferences of the back guard shelf 11;
10b is a vertical wire rod arranged parallel to the longitudinal direction of the back guard shelf 11, and 10c is a vertical wire rod 1 of these rods.
This is a transverse wire arranged perpendicular to 0b.

Four of these transverse wire rods 10c (two each on the left and right) are extended onto the rear edge of the back guard shelf 11, and two chevron-shaped bent portions 10d are formed by these extension wires (one each on the left and right). )Form.

As shown in detail in FIG. 2, it has a screw insertion hole 12a in the center and an annular groove 12 in the outer circumference
The hook 12 having the shape b is made of metal such as stainless steel or synthetic resin.

On the other hand, the back guard 1 of the sink corresponds to the two bent portions 10c formed on the back guard shelf 11.
A pilot hole 13 (see Fig. 2) is provided in each of the holes 13 and 2.
The back guard shelf 11 is attached to the sink by fixing two hooks 12 to the back guard 1a and engaging the bent parts 10d of the back guard shelf 11 with these two hooks 12.

As described above, in the present invention, the hook 12 can be fixed to the back guard 1a by screwing the tap pin screw 14 into the screw hole 13 from the front of the back guard 1a through the hook 12, so that the installation work is easy. Furthermore, even if the screw 14 becomes loose, it can be tightened from the front with a screwdriver, making maintenance work easier.

On the other hand, as shown in Fig. 7, there is a method in which a screw hole 15a is provided on the back side of the hook 15 and a small screw 16 is screwed in from the back side of the back guard 1a, but if this method is used, the screw 16 may become loose or fall off. In such cases, the back side of the back guard 1a cannot be accessed normally, making repairs extremely troublesome.

(Effect of the invention) As described above, in the present invention, the back guard shelf 11 is made of the wire rod 10, has an open top surface, and is configured in the shape of a basket with rising edges on all four sides, so that objects placed on the shelf 11 are prevented from falling. This has the effect of eliminating the risk of

Further, a screw pilot hole 13 is provided in each back guard 1a of the sink, and a hook 12 having a screw insertion hole 12a in the center and an annular groove 12b on the outer periphery is inserted into the screw insertion hole 12a. The bent portion 1 is fixed to the back guard 1a by screwing into the lower hole 13, and is formed integrally with the back guard shelf 11 on the hook 12 fixed in two places on the back guard 1a in this way.
Since the back guard shelf 11 is attached to the sink by engaging 0d, the attachment is easy, and the hook 12 and the back guard shelf 11 are securely engaged, eliminating the risk of the shelf 11 falling off. can get.
