Description

[Detailed description of the invention] This invention relates to a worktop back guard mounting structure.

As shown in Figure 1, a typical kitchen sink has a work top 2 with a sink 1 attached to its upper surface, and a back guard 3 is attached to the part of the work top 2 that comes into contact with the rear wall to prevent water from leaking through the gap between the work top 2 and the wall.

However, when trying to make the back guard 3 maintain sufficient watertightness, there was a problem in that it took time and effort to install it.

Therefore, an object of this invention is to provide a worktop back guard mounting structure that allows the back guard to be easily mounted on the work top while ensuring watertightness.

An embodiment of this invention will be explained based on FIG. In other words, the worktop back guard mounting structure is as shown in Fig. 2.
A back guard 6 placed on the edge of the
The work top 4 is tightened and fixed by a threaded rod 7 fixed to and hanging downward and a wing nut 8 screwed onto the threaded rod 7 on the back surface of the work top 4, and a groove 5 formed on the bottom surface of the partition plate 6a of the back guard 6. It is equipped with a watertight material 9 that is filled in the inside and is pressed and compressed by tightening the back guard 6 against the surface of the work top 4 and comes into close contact with the work top 4.

The back guard 6 is an extruded aluminum member, and has a partition plate 6a provided inside and a groove 5 formed on the lower surface. A threaded rod 7 hanging downward is connected to the partition plate 6a by welding or the like. On the other hand, the worktop 4 is provided with a through hole 10 through which the threaded rod 7 is inserted. Tighten and secure 6. In order to fix the threaded rod 7 to the partition plate 6a of the back guard 6, for example, the back guard 6 is divided into a plurality of parts, and the threaded rod 7 is welded or caulked near the open ends of each short back guard material. An example of this method is to twist and fix the back guard material, and then join the end faces of each back guard material to each other. Also, another method is
It is possible to adopt a method such as providing several opening windows (not shown) on the back of the back guard where the screw rods are fixed, and fixing the screw rods 7 to the partition plate 6a through these opening windows by welding, caulking, etc. be.

The watertight material 9 is filled in the groove 5 on the lower surface of the partition plate 6a of the back guard 6, and is brought into close contact with the work top 4 by pressure when the back guard 6 is installed, closing the gap between the back guard 6 and the work top 4. Prevent water from entering. In order to provide sufficient watertightness to the back guard 6 by the watertight material 9, it is preferable that the watertight material 9 is in complete contact with the worktop 4 on the lower surface.
During construction, a material with a thickness slightly larger than the distance A from the lower surface of the partition wall 6a to the upper surface of the worktop 4 is used so that the watertight material 9 is compressed to the thickness A when the back guard 6 is pressed.

With this structure, when attaching the back guard 6 to the worktop 4, a watertight material 9 of an appropriate thickness is fixed in the groove 5 on the bottom surface of the back guard 6 using double-sided adhesive tape or the like (not shown).
Then, simply insert the threaded rod 7 of the back guard 6 into the through hole 10 of the work top 4 and tighten it with the wing nut 8 from the back side of the work top 4.
The back guard 6 can be easily attached, and watertightness between the back guard 6 and the worktop 4 can also be ensured.

As described above, the worktop back guard mounting structure of this invention includes a back guard that is placed on the edge of the work top and has a groove on the bottom surface, and a back guard that is fixed inside the back guard and hangs downward and passes through the through hole of the work top. a threaded rod protruding from the back surface of the work top; a nut that is screwed into the threaded rod on the back surface of the work top to tighten and fix the back guard to the work top surface; By tightening the
By having a compressed watertight material that is in close contact with the worktop, the back guard can be easily attached to the worktop, and the watertightness between the back guard and the worktop is ensured. Since it is stored inside, it is completely hidden from the outside and has the effect of not detracting from its aesthetic appearance.
