Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an aquarium, and is particularly applicable to restaurants,
It was invented as a sink suitable for so-called commercial sinks used in hotels, restaurants, cafeterias, etc., and small bathtubs for medical purposes in which hands and feet are placed.

[Prior Art] Aquariums such as household sinks have a shallow depth and can be formed by drawing in one piece, but commercial sinks generally have a deep bottom. , and because they are often custom-made according to customer requests, they are constructed by cutting out and bending stainless steel plates with at least the sink portion expanded, without drawing.

Therefore, in the assembled state, the side plates are welded together at the center of the radius.

(Refer to Japanese Utility Model Publication No. 36-33084.) There is also an example of using a separate part for this rounded portion (Japanese Patent Publication No. 52-13477).

[Problems to be Solved by the Invention] If the side plates are welded to each other at the center of the radius, it is difficult to form a water tank with a large radius, and in fact 25 radius seems to be the limit.

Further, if a separate part is used for the rounded part, this drawback can be solved, but the number of welding and polishing parts increases, and the processing of the part becomes relatively time-consuming.

[Means for Solving the Problems] Therefore, the present invention reduces the number of welding points and eliminates wasted material by cutting out the rounded part that connects the sink part and the side plate in a single expanded shape and bending it. It was made possible to do so.

In addition, the welding points between the side plates are not rounded portions but flat portions so that the rounded portions can be beautifully finished, a water tank with a large radius can be obtained, and welding polishing is facilitated.

The gist of this invention is that the front side plate 2 extends from the bottom plate l in all directions.
, a rear side plate 3, a left side plate 4, and a right side plate 5 are installed in series, and fan-shaped projecting portions 6.6.6.6 are provided at adjacent parts of the side plates 2.3.4 and 5 on the bottom plate 1 side. Constructed as follows, corner parts are connected to the opposite edges of the left and right sides & 4.5, and these are cut out from a single stainless steel plate, and the side plates are butted against each other by these corner parts. It is characterized in that the edges of the overhanging portion also butt against each other to form a sink portion.

[Example] The following description will be made based on the embodiments shown in the drawings.

Figure 1 shows an exploded view of the sink according to the present invention, which is made by blind punching or cutting out a stainless steel plate, so that the sink part and the deck part can be made into one piece. .

Methods to be used after the blind work include punching with a punching press, shearing and cutting with scissors, and cutting with a pipe roller shear. These means are appropriately selected depending on the thickness of the manufacturing loft. Also, finish the cut surface with a sandpaper if necessary.Furthermore, in the following explanation, a fold line and a curved line will appear, but a fold line is a bend line when bending approximately 90 degrees, and a curved line is a line that serves as a starting line when bending and bending, and is for convenience of explanation. Therefore, the marking work is done using the outline. Bending is done using a hydraulic pengu, crank bender, or hydraulic press.

A front side plate 2, a rear side plate 3, a left side plate 4, and a right side plate 5 are arranged in a row in four directions from the bottom plate 1, and the side plates 2, 3°4.5 have an appropriate length depending on the depth of the sink. This side plate 2.3.4
．． The adjacent part on the bottom plate l side of 5 is a fan-shaped overhang part 6.
6.6.6 should be provided. This overhang 6
constitute the rounded portions from the bottom plate 1 to the side plates 2.3 and 4.5 at the four corners of the sink. Therefore, the overhang part 6
Side plate 2.3.4.5 from the curved line 40 connecting the center of the edge of
The length of the sink to the opposite end is the depth of the sink.

The front plate 7 is connected to the front plate 2 via a broken line 50, and the front plate 7 is continuous with quarter-circular notches 8 on both sides corresponding to the fan-shaped overhang 6. This is provided. On three sides of this front deck 7, hanging boards 9, 9, 9 are connected through the fold line 60.
is the provision.

In the rear side plate 3, the rear deck 10 is continuous with cuts 8 similar to the above-mentioned cuts 8 arranged on both sides of the rear deck 10 via a broken line 50. Drop plates 11, 11 are provided on both sides of the rear deck 10 via a fold line 60, and an upright plate 12 and a horizontal plate 13 constituting a back guard are attached to the rear deck 10 via a fold line 70, 80. They are installed consecutively.

On the opposite side of the left side plate 4 from the bottom plate 1, the left deck 14 is connected via a fold line 50, and a hanging plate 15 is further connected integrally via a fold line 60, and on both sides of the left side plate 4, Corner portions 16 and 16 forming rounded portions between the left side plate 4 and the front side plate 2, and between the left side plate 4 and the rear side plate 3 are connected via curved lines 90.

On the right side plate 5, similarly to the left side plate 4, a right deck 17 is provided along a fold line 50, a hanging plate 18 is provided along a fold line 60, and a corner portion 19, 19 is provided along a curved line 90.

Although not shown, a drainage hole is provided in the bottom plate 1, and an overflow hole is provided in the side plates 2, 3, 4, and 5, if necessary.

A method of assembling a sink having such a configuration will be explained.

First, side plate 2.3.4.5 and deck 7.10.14.17
Bend it 90 degrees along the connecting fold line 50. Next, the corner portions 16, 16, 19, and 19 are bent inwardly using the curved line 90 as a starting line. Furthermore, the sector-shaped extensions 6.6, 6 between the bottom plate l and the side plates 2.3.4.5
．． Bend the side plate 2.3.4.5 approximately 90 degrees with the curved line 40 connecting the centers of the circular arc-shaped portions 61 on the edges of the side plate 2.3.4.5.
(See Figure 2).

Next, deck 7, io, connected from side plate 2.3.4.5,
14.17 and the edges A and A of the hanging plates 9, 9.11.15.18 are butted against each other, welded together, and assembled into a box shape. Note that by welding this area first, it will prevent twisting when finished, so the deck 7.10.14.17 will be nicely level.

Furthermore, the three edges B, C, and D of the corner portion 16.19 are the arc-shaped edges Bl of the front and rear decks 7.10, the front and rear side plates 2,
3 and the edge D2 of the overhanging part 6 and weld them to each other.

At this time, the welding between the edge and the edge D2 of the overhanging portion is done last (see Fig. 3).

In this way, the sink part is completed.

Next, bend the hanging board 9.11.15.18 by 90 degrees from the deck 7.10.14.17 along the fold line 60,
The structure is approximately parallel to 3.4.5. At this time, it is desirable to bend the edges of the hanging plates 9, 11, 15, 18 in advance to prevent injury during handling.

Further, the upright plate 12 and the horizontal plate 13, which are connected to the rear side plate 3 and which are connected to the rear deck 10, are bent along fold lines 70 and 80 to provide a back guard part. At this time, both sides of 1 are open, but a rectangular steel plate 20 is separately applied here and welded.
. 1 (Of course, the welding area should be polished for finishing.

[Effects of the Invention] The present invention has the above-described configuration, and the present invention reduces the number of welding points by cutting out the rounded portion that connects the side plates into a single expanded shape and bending it. This allows you to avoid wasting materials.

In addition, the welded parts between the side plates can be made into flat parts instead of rounded parts, so that the rounded parts can be beautifully finished, making it possible to obtain an aquarium with a large rounded radius.

In addition, if only the sink part was expanded and punched and bent, the deck part would have to be made separately and welded. However, if the structure is configured as in the example, the deck part can also be cut out, so the aquarium can be cut out. Manufacturing becomes extremely simple.
