Description

Bench-integrated table and its manufacturing method

The present invention relates to a bench-integrated table in which a table and a bench are integrally formed, and a method for manufacturing the same.

In general, a bench-integrated table is an integrally formed top plate forming a table and a top plate forming a bench by a substructure, and may be referred to as an outdoor bench or an outdoor table as described below.

As an exemplary embodiment of the bench-integrated table, Korean Patent No. 1695665 (announced on December 12, 2017) includes a first seating unit provided with a first seating plate; An outdoor bench comprising a table unit provided with a main plate; and a second seating portion provided with a second seating plate; is invented. In this way, the conventional outdoor bench includes a main plate (top plate of the table) and the first and second seating plates (top plate of the bench) and the lower frames (substructures) connecting them are made of wood. Such a conventional outdoor bench is very vulnerable to fire because it is made of wood only, and as time goes by, the bonding strength of each connection part (joint part using nails, screws, and bolts) decreases, and stability decreases. Not only is it difficult to manage, such as the need to paint, but there is a disadvantage in that it is heavy because many materials are used to increase the stability of the structure.

In order to compensate for the above problems, Korean Patent No. 1921724 (announced on Nov. 23, 2018) includes a support frame 10, which is a steel structure having a'U' shape but one end higher than the other end; A table 20 made of solid wood and fixed to the other end of the support frame 10; An outdoor table comprising a wooden chair 30 fixed to one end of the support frame 10; This outdoor table has the advantage that stability is maintained over time and the structure of the lower frame is simplified and relatively light, but it is still vulnerable to fire due to the table and chair made of solid wood, and must be painted or varnished. There is a problem in that management is inconvenient.

On the other hand, it is the following problems to simply combine the flat top plate of the metal material to the bent substructure of the metal material by welding or a conventional fastening method.

First, the upper plate of the metal material is vulnerable to corrosion when formed of aluminum to prevent corrosion, and vulnerable to corrosion and heavy when formed of iron to increase durability. That is, although a table formed of aluminum is provided in the past, in this case, since the thickness of the table is thin, it is easily pressed or stamped during use. Therefore, usually, an upper plate is formed using an iron plate. In this case, a phenomenon of easily rusting due to dew or rain occurs.

Second, if the thickness of the upper plate of the metal material is thick, there is a disadvantage that it is heavy and difficult to manufacture. That is, when the top plate is formed of a metal material, a minimum thickness of 3 mm or more is required to secure safety. In this case, the thickness is thicker and heavy, so it is of course inconvenient to move, and the thick top plate is bent or cut or punched. There are many difficulties in manufacturing such as forming.

Third, the top plate of the metal material has a disadvantage of poor thermal properties. That is, since the simple aluminum plate or the iron plate is easily cooled or heated by external heat, it is difficult to use when the external temperature is low or hot.

Fourth, it is possible to fasten by welding or bolts (screws) as a method of installing the top plate of the metal material on the lower structure. In the former case, the metal panel and the lower frame are not separated, and in the latter case, the bolt is placed on the metal panel. (Screw) There is a disadvantage that the head is exposed. In this way, when formed integrally by welding, it is difficult to move or store, and when the bolt head is exposed, not only the appearance is damaged, but corrosion is easily generated therefrom.

The present invention is to form a table and a bench integrally by using a metal upper plate and a substructure to reduce the risk of fire, but structurally stable, lightweight and corrosion-free, a bench-integrated table with little heat change and a method for manufacturing the same will be.

The present invention allows the metal plate to be easily coupled and separated by fastening the upper plate and the lower structure with bolts/nuts, while the bench-integrated table does not expose bolts (screws) or nuts to the surface of the top plate and a method for manufacturing the same Is to provide

The first and second upper plates of the bench-integrated table of the present invention are formed of a composite panel filled with an inorganic flame-retardant resin (FR) layer between upper and lower aluminum layers and a frame for supporting it, and the lower structure connects the first and second upper plates. It is formed of a metal material connecting rod connecting the front and rear metal support legs and the front and back support legs.

In the first and second upper plates, as an example, the edge of the composite panel is bent to surround the lower end of the frame, and a ceramic coating layer is formed on the surface of the composite panel, and a plurality of through holes may be formed.

The first and second upper plates form a fixing bolt protruding to the lower portion of the frame, while the lower structure is formed with a fastening plate so that the bolts are fastened through the support legs.

According to the bench-integrated table and its manufacturing method of the present invention, safety against fire is improved, and stability, convenience, and usability of use are further improved.

According to the bench-integrated table of the present invention and a method for manufacturing the same, installation and storage are further improved through easy separation movement and storage, and there is an effect that the beauty is further improved by exposing the bolt or nut.

Therefore, the bench-integrated table of the present invention has an effect that can be safely and conveniently used indoors as well as outdoors.

Forming the upper aluminum layer 110a thicker than the lower aluminum layer 110c in this way is because durability for scratching or scratching from the upper side is more required for use. The inorganic flame-retardant resin layer (110b) is a mixture of inorganic materials that do not burn, and is more fire-resistant and fire-resistant than conventional synthetic resin foams that burn easily. Therefore, according to the composite panel 110, it is prevented from being corroded by the upper and

lower aluminum layers

110a and 110c, and the durability is improved as compared to that formed only by a thin aluminum panel, and lightness is high, but not only the stability against fire is high. , Since the inorganic material forming the inorganic flame retardant resin layer 110b absorbs heat and compensates for the phenomenon in which the upper and

lower aluminum layers

110a and 110c are rapidly changed by external heat, it can be safely used outdoors as well as outdoors. .

The ceramic coating layer 110d is coated using a ceramic resin, and not only forms various patterns or textures on the surface, but also prevents contamination from external environments such as acid rain, ultraviolet rays, dust, and scratches due to external pressure. It has a function to increase durability.

In the first and second

upper plates

100a and 100b, as another embodiment, a plurality of through holes H are formed in the composite panel 110 as illustrated in each drawing. The through-hole (H) not only allows the water to flow out smoothly, but also makes the ventilation smoothly. In this case, the through hole (H) may be formed on the first top plate (110a) forming a table, but is preferably formed on a composite panel of the second top plate (100b) forming a bench, the first top plate (110a) ), a hole is formed to fit the parasol.

On the other hand, as shown in FIG. 4, the first and second

upper plates

100a and 100b are formed with braille so that the visually impaired may know them, so that the visually impaired can use them freely.

At this time, the support leg 210, for example,'L' as shown in Figure 1 or'S' as shown in Figure 2 as the motif of the first upper plate (100a) coupled to the frame 120 and the upper portion of the first 2 As the upper end coupled with the frame 120 of the top plate 100b is integrally connected, it is formed in an integrally bent shape using a circular or square pipe to increase stability. In addition, the connecting rod 220 is to connect the front and rear support legs 310 to be easily separated and combined.

As the embodiment 200, as shown in FIG. 9, the fixing bolt 130 penetrates into the upper part connected to the first and second

upper plates

100a and 100b while being in close contact with the frame 120. The fastening plate 230 is formed to be fastened. That is, the fastening plate 230 is a means for easily coupling and separating the support leg 210 with the fixing bolt 130 to the frame 120. At this time, a hole is formed in the fastening plate 230 so that the fixing bolt is fitted, and it is preferable that the upper end of the support leg 210 is fixed by welding.

In the lower structure 200, as shown in FIGS. 9 and 10, coupling protrusions 211 protruding inward are formed on the front and rear support legs 210, respectively, while end portions of the connecting rod 220 are formed. It is formed to be fastened with a bolt / nut in the state where the engaging projection is fitted.

And the method for separation is applied from the features of the overall configuration described above.

In the step of cutting the composite panel 110, as shown in the upper part of FIG. 11, the composite panel 110 filled with an inorganic flame retardant resin (FR:Flame Resistance) layer between the upper and lower aluminum layers is cut to fit the dimensions. Cutting), but the front and rear or right or left edge corresponding to each corner to form a wing 111 for wrapping the side and bottom surfaces of the frame 120 integrally. That is, the present invention integrally cuts the flat composite panel 110 provided in a certain width into a form including the blade 111 using a separate cutting device. At this time, it is preferable that the cutting device is automatically cut by the input program. On the other hand, it is preferable to grind this part with a grinder because each blade 111 of the cut composite panel 110 may have a sharp edge or a burr in the process of cutting.

The step of forming the bending groove 112 is as shown in the center of FIG. 11, the bending groove 112 for wrapping the side and bottom surfaces of the frame on the lower aluminum layer 110c of each wing 111 ) Side by side. The bending groove 112 is formed by pressing using a press or roller, so that the wing 111 is easily bent. At this time, by forming the bending groove 112 on the lower aluminum layer 110c, the inorganic flame retardant resin layer 110b is formed with a pressing corresponding to the bending groove, but the upper aluminum layer 110a is not pressed. .

The step of wrapping and fixing the frame 120 is to place the frame 120 on the lower aluminum layer 110c of the composite panel 110 as shown in the lower portion of FIG. 11, and to fly along the bending groove 112. By bending (111), it is fixed by wrapping the side and bottom surfaces of the frame. At this time, it is preferable to prevent the wings from being opened by use by fixing a screw to the wing surrounding the lower surface of the frame by the bending as shown in the drawing.

The present invention comprises a step of closing the gap between the bent wings in contact with each other in a state in which the bent wings surround the frame, as shown in FIG. That is, since a gap occurs due to the thickness of the composite panel at the joint where the bent wings come into contact with each other, the part is grinded with a grinder and then the filling gap 113 is filled in the gap. At this time, the closing of the filling material 113 is particularly necessary in a portion where the bent wings, such as the corners of the first top plate, abut at a right angle, and the edge wings are separately separated through'V' cutting, such as the edge of the second top plate. In the case of formation, the gap in the contact portion during bending is small, so that the filling material can be selectively filled to finish.

According to the configuration and manufacturing method of the present invention, since the first and second upper plates and the lower structure are made of a metal material, the risk of fire is reduced, and the use of the composite panel itself is stable, light and without corrosion. It is very convenient to use because there is little heat change.

In addition, the present invention allows the first and second upper plates and substructures of a metal material to be easily coupled and separated by bolts/nuts, while bolts (screws) or nuts are used as the surfaces of the first and second upper plates. There is a feature that is not exposed.

Therefore, the present invention can be installed and used outdoors, such as a pension or a park, as well as less risk of fire, easy disassembly and assembly, and has a beautiful appearance, so that it can be installed and used indoors, such as a kitchen or cafe. .
