Description

Technical Field

[0001] The present invention relates to a table with a movable stand that can be provided for people to stand and eat, and also to a standing table that allows each person to recognize a dedicated area for placing their own tableware when shared and used by multiple people, and also to a standing meal service system that generates magnetic lines of force between tableware placed on the tabletop of the table to stably arrange the tableware on the tabletop and pay attention to keeping the cooking dishes warm, and also to a standing table system that connects these movable standing tables and standing meal service systems to dynamically configure a large table and a method for connecting movable standing tables.

Background Art

[0002] Conventionally, at a standing party, it is common to gather around a plurality of large round tables arranged separately in the venue and chat. As a tool devised to hold cups and glasses used, only a plate held by being grasped by a finger is provided. The former is restricted by the arrangement of the large round table, inconvenient for freely inviting others and starting individual business talks or confidential conversations. The latter is inconvenient for clapping or shaking hands even if one can move freely. Moreover, it cannot create an atmosphere of sharing a social space of surrounding the same table, and is not suitable for a standing party to create an opportunity for a close personal relationship.

[0003] When chatting around a large round table, the conversation partners are limited to those sitting next to each other. Even if three people chat along the round table, they have to speak loudly, which is far from a conversation method suitable for this era of the spread of airborne infectious diseases. On the other hand, if it is a small round table, it is possible to gather several like-minded people around the round table and chat in a calm atmosphere. However, as the number of round tables increases, the organizer has trouble arranging them.

[0004] Rather, small round tables can be configured to be movable, and since they are easy to move, it would be appropriate to allow participants to move them around as they like and leave the arrangement of the round tables to them. However, in this case, it is possible that dishes may accidentally tip over due to movement, so appropriate precautions would be desirable.

[0005] By the way, while a party style with a round table can foster an atmosphere of sharing a social space by sitting around the same table, everyone has probably experienced at least once wondering, "Which glass was mine?" after putting their glasses down, chatting, and eating.

[0006] Alternatively, at parties, except when cold or dry dishes are served in small plates, hot dishes are served on a large platter with a heat source underneath before being portioned into smaller plates. For example, a heating candlestick might be placed at a distance below the platter, or the bottom of the platter might be heated by a warm bath. However, once the food is placed in small plates, it has no choice but to cool down. Lighting candlesticks on a small round table, or using a warm bath to keep food warm in a movable setup, both raise safety concerns.

[0007] On the other hand, in self-service restaurants, when people with disabilities use these establishments, they may hesitate to use them if it is difficult for them to obtain or have the opportunity to receive support from other able-bodied people. Occasionally, large four-wheeled carts are provided for self-service use to facilitate the use of these establishments by people with disabilities, but such restaurants are rare.

[0009] At standing receptions, making the round tables as small as possible allows for more hygienic behavior, as it reduces the need to raise voices to those on the other side of the table. However, making the round tables small also means that people are positioned closer to each other, increasing the risk of mixing up one's own tableware with that of the person being conversed with. Furthermore, smaller round tables mean fewer participants per table, leading to a dramatic increase in the number of round tables and a greater burden on the reception venue manager. At many standing receptions, people become so engrossed in conversation that they linger on their plates for extended periods, causing the food to cool down.

[0010] The present invention was made in view of these circumstances, and its purpose is to provide a movable table for standing receptions that increases opportunities for participants to converse without increasing the burden on administrators in setting up round tables.

[Modes for carrying out the invention]

[0080] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. First, an embodiment of the standing table 1 according to the present invention will be described with reference to Figures 1 and 2. Figures 1 and 2 are schematic perspective views and schematic top views of a standing table according to a preferred embodiment of the present invention. The standing table 1 has a plurality of legs 2 that are movable adjacent to the floor surface A, A single pillar 3 is joined to the leg 2 and supported upward relative to the floor surface A, The standing table 1 is characterized by having a tabletop 4 horizontally supported by the pillar 3, and having markings 8 on the upper surface 5 of the tabletop 4 that, when viewed from above in a plan view, should be identifiable as a plurality of sections 6, 7. As disclosed in Figure 1, casters 9 may be attached to the lowest part of the legs 2 so as to be rotatable about a vertical axis and movable on the floor surface A. The tabletop and pillars may be made of wood or plastic resin material, and in the following embodiments, glass material may be used for the top plate when heat resistance is a concern, unless otherwise specified.

[0081] The effects and advantages of a standing buffet table 1 disclosed in one embodiment of the present invention will be explained with reference to Figures 1 and 2. A standing buffet table 1 is, for example, a table that is to be shared by multiple people, and is intended for placing individual tableware such as cups and mugs for drinks, and plates for individual servings of food such as à la carte dishes and main courses. When multiple people use such a table while conversing, it is often unclear who is using which piece of tableware. In such cases, asking for additional tableware spoils the mood and can interrupt the conversation. On the other hand, with the spread of airborne infectious diseases these days, sharing food plates should also be avoided for public health reasons.

[0082] In response to such needs, the standing table 1 according to the present invention is characterized by having markers 8 to distinguish multiple sections 6 and 7. In Figure 1, the linear grooves 10 provided on the tabletop 4 act as markers 8 for the sections to be used by each person, and each person can recognize that the sections 6 and 7 separated by the linear grooves 10 and surrounded by the outer edge of the tabletop 4 are their own dedicated areas. In the standing table 1 shown in this embodiment 1, the top surface 5 of the tabletop 4 is divided into two sections 6 and 7 by a single straight linear groove 10. However, the linear groove 10 does not necessarily have to be straight, and although not shown in the figure, in a plan view from above, it may also be wavy, broken, or a free curve. In this embodiment, the standing table 1, as shown in the schematic plan view 2 of the top surface, has a circular top plate 4 in plan view. However, it does not have to be a perfect circle; it may be an ellipse or a flat plate forming a closed region with a free curve. The number of sections to be separated is not necessarily limited to two as shown in the figures. It may also be a linear groove that separates the table into three sections by three straight linear grooves (not shown) passing through the center of the top surface 5 of the top plate 4, or a linear groove that separates the table into four sections by two straight linear grooves (not shown) passing through the center of the top surface 5 of the top plate 4 and intersecting at the center. Thus, the number of sections is not limited to two as shown in Figures 1 and 2.

[0083] Thus, the standing table 1 shown in Figure 1 is disclosed, which has a plurality of legs 2 adjacent to the floor surface A so as to be movable, a single pillar 3 joined to the legs 2 and supported upward relative to the floor surface, and a tabletop 4 horizontally supported by the pillar 3, and the upper surface 5 of the tabletop 4 has markings 8 which should be identified as a plurality of sections 6,7 in a plan view from above, and the markings 8 include linear grooves 10 provided on the upper surface 5 of the tabletop 4.

[0084] At the standing table 1, each person recognizes their own dedicated area as a private section 6,7 enclosed by the linear groove 10 and the outer edge of the tabletop 4. By placing their own tableware in this area, they can prevent the mixing of tableware with others and enjoy the benefit of a safer eating environment.

[0085] Next, an embodiment 100 of the standing table 1 according to the present invention, based on the first embodiment, will be described with reference to Figures 3 and 4. Figure 3 is a schematic perspective view of the upper surface 105 of the tabletop 104 of the standing table 101 in embodiment 100, viewed from above, and Figure 4 is a schematic plan view of the upper surface 105 of the tabletop 104 of the standing table 101, viewed from above. In embodiment 100, in Figure 3, linear projections 110 provided on the upper surface 105 of the tabletop 104 act as markers 108 for areas to be used by each person, and each person can recognize that the areas 106 and 107 separated by the linear projections 110 and surrounded by the outer edge of the tabletop are their own dedicated areas. In embodiment 100, casters 109 may also be attached to the lowest part of the legs 102 to allow movement on the floor surface A.

[0086] Thus, the standing table 101 shown in Figures 3 and 4 is disclosed, which has a plurality of legs 102 adjacent to the floor surface A so as to be movable, a single pillar 103 joined to the legs 102 and supported upward relative to the floor surface A, and a tabletop 104 horizontally supported by the pillar 103, and the upper surface 105 of the tabletop 104 has markings 108 which should be identified as a plurality of sections 106, 107 in a plan view from above, and the markings 108 include linear projections 110 provided on the upper surface 105 of the tabletop 104.

[0087] At the standing table 101, each person recognizes their own dedicated area as a private section 106, 107 enclosed by the linear projections 110 and the outer edge of the tabletop 104, and by placing their own tableware in this area, the mixing of tableware with others is prevented, and a safer eating environment is provided.

[0088] In one embodiment 100, the top plate 104 is divided into two dedicated compartments 106 and 107 by a single linear projection 110. However, the dedicated compartments are not limited to two; they may be divided by two or more linear projections, resulting in three or more or four or more compartments, as in the case of embodiment 1.

[0089] Next, an embodiment 200 of a variation of the standing table 1 according to the present invention, based on the first embodiment, will be described with reference to Figures 5 and 6. Figure 5 is a schematic perspective view of the upper surface 205 of the tabletop 204 of the standing table 201 in the embodiment 200, viewed from above, and Figure 6 is a schematic plan view of the upper surface 205 of the tabletop 204 of the standing table 201, viewed from above. The standing table 201 is characterized in that the indicator 208 includes a configuration in which the upper surface 205 of the tabletop 204 is identified by coloring each section 206, 207 with a color 211, 212. The color 211 is, for example, white, and the color 212 is, for example, black. In the case of the standing table 201, what corresponds to the marker 208 of the standing table 201 is the boundary of the crescent-shaped colored areas 211 and 212 in a plan view. This is not formed as a marker 208 in itself, but is represented as the boundary of the colored areas 211 and 212 of each section 206 and 207, and can also be considered a marker. In the case of the standing table 201, casters 209 may be attached to the lowest part of the legs 202 so as to be rotatable around a vertical axis, allowing it to move freely on the floor surface A.

[0090] At the standing table 201, each person recognizes their own dedicated area as a designated zone 206, 207, with the boundary of the colored areas 211, 212 marked by a marker 208 and the areas on either side of it designated as dedicated sections. By placing their own tableware in this area, the mixing of tableware with others is prevented, and a safer eating environment is provided.

[0091] Thus, the standing table 201 shown in Figures 5 and 6 is disclosed, which includes a plurality of legs 202 adjacent to the floor surface A so as to be movable, a single pillar 203 joined to the legs 202 and supported upward relative to the floor surface A, and a tabletop 204 horizontally supported by the pillar 203, and the upper surface 205 of the tabletop 204 has markings 208 that should be identified as a plurality of sections 206, 207 in a plan view from above, and the upper surface 205 of the tabletop 204 is identified by coloring each of the sections 206, 207.

[0092] In one embodiment 200, the top surface 205 of the top plate 204 is divided into two dedicated sections 206 and 207 by two colors 211 and 212. However, the number of dedicated sections is not limited to two. The top surface 205 of the top plate 204 may be divided by three or more colors, or it may be separated into four or more sections by four or more colors, as in the first embodiment.

[0093] Next, an embodiment 300 of the standing table 1 according to the present invention, based on the first embodiment, will be described with reference to Figures 7 and 8. Figure 7 is a schematic perspective view looking down from above at the upper surface 305 of the tabletop 304 of the standing table 301 in the embodiment 300, and Figure 8 is a schematic plan view of the upper surface 305 of the tabletop 304 of the standing table 301, viewed from above. A step 310 is formed on the upper surface 305 of the tabletop 304, and the upper surface 311 and lower surface 312 adjacent to the step 310 are recognized as dedicated sections 306 and 307, respectively. By placing each person's tableware in this area, the mixing of tableware with others is prevented, and a safer eating environment is provided. In the standing table 301 of one embodiment 300 shown in Figure 7, the upright wall surface 310 adjacent to the upper surface 311 and lower surface 312 of the stepped portion 310 is designated as a marker 308 to identify sections 306 and 307.

[0094] At the standing table 301, each person recognizes their own dedicated area as a marker 308 on the upright wall 310 connecting the upper surface 311 and the lower surface 312, which are separated by a step 310. The areas adjacent to this marker on each step surface are recognized as dedicated sections 306 and 307, and by placing their own tableware in these areas, the mixing of tableware with others is prevented, and a safer eating environment is provided.

[0095] Thus, the standing table 301 shown in Figures 7 and 8 is disclosed, which has a plurality of legs 302 adjacent to the floor surface A so as to be movable, a single pillar 303 joined to the legs 302 and supported upward relative to the floor surface A, and a tabletop 304 horizontally supported by the pillar 303, and has markings 310 on the upper surface 305 of the tabletop 304 which should be identified as a plurality of sections 306, 307 in a plan view from above, and the markings are configured such that the upper surface 305 of the tabletop 304 includes a step 310, and the upper surface 306 and lower surface 307 of the step 310 are adjacent to the wall surface 310.

[0096] In one embodiment 300, the top surface 305 of the top plate 304 is divided into two dedicated sections 306 and 307 by a sign 308. However, the number of dedicated sections is not limited to two. Multiple stepped surfaces of different heights can be provided, and the upright walls 310 of adjacent stepped surfaces can be used as the boundary between the dedicated sections 306 and 307 and recognized as signs 308. The top surface 305 of the top plate 304 may be divided by the formation of three or more stepped surfaces, or it may be separated into four or more sections by four or more stepped surfaces.

[0097] Furthermore, the step may be formed by creating a recessed planar region (not shown) that is lowered from the upper surface 305 of the top plate 304. A marker 308 may be formed with an upright wall surface connecting the recessed planar region and the upper surface as a boundary so that this recessed planar region can be recognized as one of the dedicated compartments, and a desired number of dedicated compartments may be formed by creating a desired number of recessed surfaces (not shown) on the upper surface 305 of the top plate 304.

However, if the sole purpose is to lighten the standing table 351, a standing table including reinforcing ribs extending vertically downward from the tabletop 354 may be constructed (not shown), provided that areas for separating individual tableware by markings are provided in the other forms described above. In other words, the tabletop 354 may include reinforcing ribs extending vertically upward or downward from the tabletop 354 in order to achieve the objective of the above invention.

[0101] Figure 9 discloses a standing table 351 equipped with reinforcing ribs 361, 362, and 363 as markers 358 that constitute sections 366, 367, and 368.

More preferably, as shown in Figure 13, the support structure 407 for the DC power module may be housed at the upper end of the single pillar 403, making it easy to load a battery or rechargeable battery 410.

[0110] A standing table 401 configured to include an electromagnetic induction heating (IH) heater mechanism 416 as an electrical component disclosed in one embodiment of the present invention will be described in more detail with reference to Figure 14. In the standing table 401 according to Embodiment 400, the tableware 414 is kept warm by the IH coil of the electromagnetic induction heating (IH) heater mechanism 416 (hereinafter, "the IH coil of the electromagnetic induction heating (IH) heater mechanism 416" will also be simply referred to as "the IH coil 416"). Figure 14 is a block diagram showing the configuration of a preferred electromagnetic induction heating (IH) heater mechanism 416 and an electromagnetic induction heating (IH) heater control device 417 of the standing table 401 according to one embodiment of the present invention. Figure 14 shows a configuration block diagram representing the DC power supply module 1100, the main control module 1101 configured within the electromagnetic induction heating (IH) heater control device 417 for controlling the electromagnetic induction heating (IH) heater mechanism 416, and the inverter control module 1102 for generating high-frequency current and supplying it to the IH coil 416. The configuration block diagram conceptually represents the electromagnetic induction heating (IH) heater mechanism 416 and the electromagnetic induction heating (IH) heater control device 417, which are located inside the tableware 414 and the countertop 404 below it, as shown in Figure 13. A partially enlarged section of a schematic cross-sectional view of the countertop 404 from a side view is superimposed to show the configuration block diagram. In Figure 14, the component blocks of each control module constituting the electromagnetic induction heating control device 417 built into the standing table 401 are described as follows: Block 1100 schematically represents the DC power supply module of the battery or storage battery 410; Block 1101 represents the main control module 1101 for controlling the IH coil of the electromagnetic induction heating (IH) heater mechanism 416; and Block 1102 represents the inverter control module 1102 for converting the DC supplied from the DC power supply module 1100 to AC in order to generate the high-frequency current that flows to the IH coil of the electromagnetic induction heating (IH) heater mechanism 416.The DC power supplied from the battery 410, which is held in the support structure 407 of the DC power module built into the pillar 403 of the standing table 401 shown in Figure 13, is supplied from the DC power module 1100, as shown by the arrow → in Figure 14, and is converted to a high-frequency current of, for example, 20k~30kHz or higher by the inverter control module 1102 via the control of the main control module 1101, and the IH coil (hereinafter referred to as "IH coil of the electromagnetic induction heating (IH) heater mechanism 416") located inside the tabletop 404 When a high-frequency current flows through the coil (which is also simply called the "IH coil 416"), magnetic field lines 418 are generated surrounding the IH coil 416. These magnetic field lines 418 generated from the IH coil 416 induce eddy currents through electromagnetic induction in a metal material 415 embedded in or attached to the bottom of a dish 414 separated by an insulator, the top plate 1013. Joule heat is generated in the metal material 415 at the bottom of the dish 414 due to electrical resistance, and adjacent dishes 414 are heated by heat conduction through the metal material 415 heated by induction. The IH coil 416 uses Litz copper wire, which is made by twisting together dozens of thin copper wires, to minimize the effects of the skin effect in the high-frequency range. Thus, a standing table 401 is disclosed which, by using DC power supplied from the DC power module 1100, electromagnetic induction heats the metal material 415 through the electromagnetic induction action of the IH coil 416, thereby keeping the dishes 414 warm.

As shown in Figure 15, the standing table 1001 receives DC power from a battery or storage battery built into the pillar 1003, via the support structure 1037 of the DC power module, and the DC power supplied from the DC power module 1100 is converted to a high-frequency current of, for example, 20k~30kHz or higher by the inverter control module 1102 via the control of the main control module 1101, as shown in Figure 18. This power is then used to power the induction heating (IH) coil of the electromagnetic induction heating (IH) heater mechanism 1016 located inside the tabletop 1004 (hereinafter referred to as "the induction heating (IH) coil of the electromagnetic induction heating (IH) heater mechanism 1016"). When a high-frequency current flows through the IH coil (also simply called "IH coil 1016"), magnetic field lines 1018 are generated surrounding the IH coil 1016. These magnetic field lines from the IH coil induce eddy currents through electromagnetic induction in the iron-based metal material 1015 embedded in or attached to the bottom of the dishware 1014, separated by the insulator top plate 1013. Joule heat is generated in the metal material 1015 at the bottom of the dishware 1014 due to electrical resistance, and the adjacent dishware 1014 is heated by heat conduction through the metal material 1015 heated by induction. The IH coil 1016 uses Litz copper wire, which is made by twisting together dozens of thin copper wires, to minimize the effects of the skin effect in the high-frequency range. Thus, a standing table 1001 is disclosed, in which the DC power supplied from the DC power module 1100 causes the metal material 1015 to be electromagnetically heated by the electromagnetic induction action of the IH coil 1016, thereby keeping the tableware 1014 warm.Furthermore, a standing table 1001 is provided in which a more suitable eating environment can be provided, preferably by arranging a temperature sensor (not shown) directly below the top plate 1013 and providing the output from the temperature sensor to the main control module 1101.

[0116] As shown in Figure 15, in the standing buffet table 1001 according to Embodiment 1000, a warming function is provided for the tableware 1014 placed in the section 1007 in which an electromagnetic induction heating (IH) heater mechanism 1016 is embedded, thereby providing a more comfortable dining environment. The upper surface 1005 of the tabletop 1004 of the standing buffet table 1001 has markings 1008 formed at the boundaries of the colors 1011 (white) and 1012 (black), forming multiple sections 1006 and 1007. Since the upper surface of the tabletop has markings to be identified by the multiple sections, each participant can easily remember the position of their tableware relative to the markings. Recalling memories This helps prevent the mixing of tableware and also has the effect of suppressing the spread of infectious diseases.

[0117] As described above, several embodiments of standing buffet tables including an electromagnetic induction heating (IH) heater mechanism have been explained. However, the standing buffet tables described herein may also be further configured to have markings on the top surface of the tabletop that, when viewed from above in a plan view, indicate that the top surface of the tabletop is divided into multiple sections by means other than coloring. These also have the effect described above of markings on the top surface of the tabletop that indicate that the top surface is divided into multiple sections, that is, each participant can easily remember the position of the tableware they place in relation to the markings. Recalling memories This can help prevent the mixing of tableware, and it goes without saying that this directly contributes to suppressing the spread of infectious diseases.

[0118] In this case, the markings may be a standing table characterized by a configuration that includes linear grooves or linear protrusions provided on the top surface of the tabletop, or a configuration in which the top surface of the tabletop is identified by coloring each section, or a configuration in which the top surface of the tabletop is identified by coloring each section, or a configuration in which the top surface of the tabletop includes a step and includes wall surfaces adjacent to the upper and lower surfaces of the step, or a configuration in which sections are formed by reinforcing ribs extending vertically upward from the top surface of the tabletop, or includes at least two of these configurations, and the sections formed by the upright wall surfaces formed by the stepped surface formed by the step may be recessed surfaces, and the effect of each marking to be identified in these multiple sections is that each participant can easily remember the position of the tableware they place in relation to the markings, Recalling memories It goes without saying that this can help prevent the mixing of tableware and thus have the effect of suppressing the spread of infectious diseases.

[0119] Next, an embodiment 1400 of the standing table 1401 according to the present invention, which is a variation of the standing table 371 according to the present invention in embodiment 370, in which a structure including a magnet is embedded on the upper surface side of the tabletop of the standing table, will be described with reference to Figures 19 to 22. Figure 19 is a schematic perspective view of the top surface 1405 of the tabletop 1404 of a standing table 1401 in one embodiment 1400, viewed from above; Figure 20 is a schematic plan view of the top surface 1405 of the tabletop 1404 of the standing table 1401, viewed from above; Figure 21 is a schematic cross-sectional view of a side view of a partially enlarged section showing the tabletop portion of the XX-XX cross-section of the tabletop 1404 in Figure 20; and Figure 22 is a schematic perspective view of the standing serving system 1420 and the standing table 1401, viewed from above, when a cup 1414 of tableware, which includes a structure made of iron and stainless steel material that is attracted to magnets at its base, is placed on the top surface 1405 of the tabletop 1404 of the standing table 1401. One embodiment 1400 discloses a standing table 1401 characterized in that a structure 1413 including a magnet is embedded on the upper surface 1405 side of the tabletop 1404 of the standing table 1401. Embodiment 1400 discloses a standing-only serving system 1420 that includes a standing-only table 1401 and tableware 1414 to be used simultaneously with the standing-only table 1401, wherein the tableware 1414 is made of a metal material including iron or a magnetic stainless steel member, or a metal material (not shown) including iron or a magnetic stainless steel member is attached or embedded to the bottom surface of the tableware 1414, and a magnetic member 1413 is attached or embedded to at least a part of the upper surface 1405 of the tabletop 1404 of the standing-only table 1401 that faces the bottom surface of the tableware 1414, and the tableware 1414 is configured to be attracted to the tabletop 1404 by magnetic force when placed on it.

[0120] As shown in Figure 19, in one embodiment 1400, a standing table 1401 is disclosed that has a plurality of legs 1402 adjacent to a floor surface A so as to be movable via casters 1409, a single pillar 1403 joined to the legs 1402 and supported upward relative to the floor surface A, and a tabletop 1404 horizontally supported by the pillar 1403, and a support structure 1437 for a DC power module including a battery or rechargeable battery 1410, in which an annular magnet 1413 is embedded in the upper surface 1405 of the tabletop 1404 when viewed from above, and as shown in Figure 22, a metal material (not shown) is included in at least the bottom of the tableware 1414, or the entire tableware 1414 is made of a metal material, and the tableware 1414 is placed in a position opposite the magnet 1413, and an embodiment of the standing table 1401 according to the present invention is disclosed that utilizes the magnetic attraction force acting between them.

[0121] A magnet 1413 is embedded in the upper surface 1405 of the tabletop 1404, so that tableware 1414 made of a magnetic material, such as a stainless steel cup 1414 made of SUS430, is attracted to it. When such tableware 1414 is used with a standing table 1401, the magnetic force on the upper surface 1405 of the tabletop 1404 holds the cup 1414 in place on the upper surface 1405 of the tabletop 1404, preventing the tableware from shaking when the standing table 1401, which is movable on the floor A, is moved, and providing a more comfortable eating environment. Furthermore, a standing serving system 1420 having the standing table 1401 and the cup 1414 as components is also disclosed in Figure 22.

[0122] Specifically, Figure 22 discloses a standing-only serving system 1420 characterized by including the above-mentioned standing-only table 1401 and tableware 1414 to be used simultaneously with the table 1401. The standing-only serving system 1420 includes a standing-only table 1401 on which a magnetic member 1413 is attached or embedded, and tableware 1414 made of a metal material having magnetic properties, such as a stainless steel cup 1414 made of SUS430.

[0123] The tableware 1414 used in the standing-style serving system 1420 may be a cup 1414 made entirely of a magnetic material, but even if it is not, the standing-style serving system 1420 is disclosed herein which can achieve the required effect with any tableware, including a cup 1414 or other tableware such as a plate, as long as a metal material, including an iron or magnetic stainless steel member, is attached to or embedded in the bottom surface of the tableware 1414.

[0124] The magnetic material 1413 does not have to be embedded across the entire surface; it may be embedded scattered on the upper surface 1405 of the top plate 1404 in a plan view from above, or it may be embedded in a horseshoe shape in a plan view from above, or it may be configured in an annular shape as disclosed in Figures 19, 20, and 22. The N and S poles of the magnetic material may be configured to be magnetized in the height direction, if the direction from the top surface to the bottom surface within the top plate is called the height direction, so that the N and S poles are oriented, or the N and S poles may be oriented so that they are magnetized in the radial direction of the disk in the plane.

[0125] In one embodiment 1400, the magnet 1413 is embedded in the upper surface 1405 of the top plate 1404, but even if the magnet is not embedded, a component containing a magnet may be attached to the surface 1405 of the top plate 1404. Furthermore, the magnetic component 1413 may be individually placed within the sections 1406 and 1407, which are divided by the colors 1411 and 1412 and separated by the mark 1418, or multiple magnetic components may be placed within these sections.

[0126] Therefore, focusing on the standing table 1401, Figures 19-22 show a standing serving system 1420 including the standing table and tableware 1414 to be used simultaneously with the standing table, which has a plurality of legs 1402 adjacent to the floor A so as to be movable via casters 1409, a single pillar 1403 joined to the legs 1402 and supported upward relative to the floor A, and a tabletop 1404 horizontally supported by the pillar 1403, and a direct battery or rechargeable battery 1410 included Disclosed is a standing table 1401 having a support structure 1437 for a power supply module, wherein a magnetic member 1413 is attached to or embedded in at least a part of the upper surface 1405 of the tabletop 1404 of the standing table 1401, which is positioned opposite the bottom surface of a dish 1414 that includes a metal member including an iron or magnetic stainless steel member at least at its bottom, and the dish 1414 is configured to be attracted to the tabletop 1404 by magnetic force. With this configuration of the present invention, the tabletop of the standing table according to the present invention and the dish work together to increase the attractive force, and even when the standing table is moved, the attractive force due to the magnetic lines of field makes the dish more stable and provides a more comfortable dining environment.

[0127] Furthermore, in embodiment 1400, as shown in Figure 21 (a schematic cross-sectional view of a partially enlarged view of the tabletop portion of the tabletop 1404 at the XX-XX cross-section in Figure 20), the tabletop 1404 of the standing dining table 1401 includes, at least a part thereof, a coil member 1435 for an electromagnet and an electromagnet control device 1436 for controlling the current to the electromagnet coil 1435. The electromagnet control device 1436, which is supplied with DC power via a support structure 1437 of a DC power module including a battery or rechargeable battery 1410, controls the attractive force between the tabletop 1404 and the tableware 1414. This provides the effect of making the tableware more stable and providing a more comfortable dining environment even when the standing dining table is moved. When moving a standing-style dining table, a magnetic field is dynamically generated by the current flowing through a coil, stabilizing tableware with magnetic attraction when needed. During eating, the electromagnetic force is dissipated via an electromagnet control device, preventing the attraction from interfering with eating, thus providing a more comfortable dining environment.

[0128] Furthermore, the magnetic force used in the standing-style serving system 1420 may be configured as follows. In the configuration according to the present invention, the tableware 1414 is a cup or glass that should hold liquid, and the magnetic force generated between the magnet embedded in the top plate 1404 and the tableware 1414, which is made of a metal material including iron or a magnetic stainless steel member, is such that when the cup or glass is filled to about 80% with liquid, even if the top plate 1404 is suddenly moved horizontally to the point where the liquid should spill out, the cup or glass will remain in the position it was placed on the top plate 1404 despite the horizontal movement of the top plate 1404. Here, horizontal movement refers to movement along a horizontal plane, in a direction perpendicular to gravity. This is different from movement that follows the floor surface when the floor surface is inclined. The standing-style serving system 1420 discloses a suitable standing-style serving system 1420 that, with respect to the magnetic force between the tabletop 1404 and the tableware 1414, ensures that no abnormalities occur in the position where cups or glasses are placed under conditions of normal use. With this configuration of the present invention, the appropriate magnetic force to be generated can be quantified, and the sliding and tipping of cups or glasses can be prevented more reliably.

[0129] Furthermore, in the standing-style serving system 1420 according to the embodiment described herein, the tableware is a cup or glass that should hold liquid, and the magnetic force generated between the tableware 1414, which contains at least a portion of a magnetic material such as a metal material including iron or a magnetic stainless steel member, and the magnetic member 1413 embedded in the top plate 1404 is such that, when the cup or glass is filled to eight-tenths of the capacity with liquid, the tableware is configured to generate a predetermined magnetic force sufficient to prevent the cup or glass from moving relative to the top plate 1404 even when the top plate 1404 is tilted to the extent that the liquid would spill out. The standing-style serving system 1420 hereby provides a suitable standing-style serving system 1420 that, with respect to the attractive force between the top plate 1404 and the tableware 1414, does not cause any abnormalities in the use of the cup or glass under conditions that would normally be used. With the configuration of the present invention, the appropriate magnetic force to be generated can be quantified, and the slipping and tipping of the cup or glass can be prevented more reliably.

[0130] Next, an embodiment 1500 of the standing table 1401 according to the present invention, which relates to Embodiment 1400, will be described with reference to Figures 23 to 26. Figure 23 is a schematic perspective view from above of a standing table 1501 whose top surface is covered with a metal material 1515, which is to be used as a component of a preferred standing serving system 1520 according to one embodiment of the present invention. Figure 24 is a schematic perspective view from above of a standing serving system 1520 in which tableware 1514, held in a sleeve 1516 containing a magnet 1513 on its bottom surface, is placed on the standing table 1501. Therefore, Figure 24 shows the standing table 1501, the sleeve 1516 containing a magnet 1513 on its bottom surface, and a cup which is tableware 1514 held in the sleeve 1516 as components of the standing serving system 1520. Figure 25 is a schematic plan view from above of a standing-only serving system 1520 in which tableware held in a sleeve containing a magnet on its bottom surface is placed on a standing-only table in one embodiment 1500. Figure 26 is a schematic cross-sectional view of a standing-only serving system 1520 in side view, in which a suitable tableware 1514 according to one embodiment of the present invention is held in a sleeve 1516 containing a magnet 1513 on its bottom surface. Figure 26 is a schematic cross-sectional view of the standing-only table 1501 and the tableware 1514 held in the sleeve 1516, which are components of the standing-only serving system 1520 in Figure 25, in which the tableware 1514 is held in the sleeve 1516 and placed on the standing-only table 1501. In one embodiment 1500, the standing table 1501, which is a component of the standing serving system 1520, is a standing table 1501 as shown in Figure 23, having a plurality of legs 1502 adjacent to each other so as to be movable with respect to the floor surface A via casters 1509, a single pillar 1503 joined to the legs 1502 and supported upward relative to the floor surface A, and a tabletop 1504 horizontally supported by the pillar 1503, and having a support structure 1537 for a DC power module including a battery or rechargeable battery 1510, and the standing table 1501 is characterized in that the upper surface 1505 of the tabletop 1504 is covered with a metal material 1515 including a metal material including iron or a magnetic stainless steel member.

[0131] Therefore, focusing on the standing table 1501, Figures 23-26 show a standing serving system 1520 including the standing table 1501 and tableware 1514 to be used simultaneously with the standing table 1501, comprising a plurality of legs 1502 adjacent to each other and movable via casters 1509 to the floor A, a single pillar 1503 joined to the legs 1502 and supported upward relative to the floor A, and a tabletop 1504 horizontally supported by the pillar 1503, and a DC power module including a battery or rechargeable battery 1510. A standing table 1501 having a support structure 1537 is disclosed, characterized in that a metal material 1515 including an iron or magnetic stainless steel member is attached or embedded to at least a part of the upper surface 1505 of the tabletop 1504 of the standing table 1501 that faces the bottom surface of the tableware 1514 to which a magnet 1513 is attached or embedded, or a sleeve 1516 for holding the tableware, and the tableware 1514 is attracted to the tabletop 1504 by magnetic force.

[0132] As shown in Figure 26, the top surface 1505 of the tabletop 1504 is covered with a metal material 1515 including an iron or magnetic stainless steel member, and the tableware 1514 is attracted by the magnetic force of a magnetic dish or a sleeve 1516 for holding the dish, thus providing the function of keeping the dish 1514 in the position it is placed on the tabletop 1504, preventing the dish from shaking when the movable standing table 1501 is moved, and potentially providing a more comfortable dining environment. Disclosed hereby are a standing table 1501 and a standing serving system 1520.

[0133] Figure 26 discloses a standing-only serving system 1520 in which a standing-only table 1501 and tableware 1514 to be used simultaneously with the table 1501 are held in a sleeve 1516. The standing-only serving system 1520 includes a standing-only table 1501 whose top plate 1504 is covered with a metal material 1515 including iron or a magnetic stainless steel member, and tableware 1514 and a sleeve 1516 in which a structure 1513 including a magnet is attached to or embedded in the bottom surface of the sleeve 1516 that holds the tableware 1514.

[0134] The tableware 1514 used in the standing-style serving system 1520 may have a configuration in which a structure containing a magnet is directly attached to or embedded in the bottom surface of the tableware 1514 (not shown in Figures 24-26), or, as disclosed in Figure 26, the tableware 1514 may be held on the outside by a sleeve 1516, and a structure containing a magnet 1513 may be disposed on the bottom of the inner surface of the sleeve 1516, and the tableware 1514 may have a structure containing a magnet 1513 disposed on the bottom surface of the sleeve 1516 and on the top surface of the tabletop 1504 of the standing-style serving system 1520 on the standing-style table 1501 The magnetic force acting between the attached magnetic metal material 1515 and the tableware 1514 is attracted to the tabletop 1504 via the sleeve 1516, and the tableware 1514 may be attracted and held on the upper surface 1505 of the tabletop 1504 via the sleeve 1516. With this configuration that utilizes magnetic force, the tableware 1514 can be a cup 1514 or other tableware such as a plate, and the required effect can be achieved. A standing table 1501 that provides a more comfortable eating environment is disclosed. Simultaneously, Figure 26 also discloses a standing serving system 1520 consisting of the standing table 1501 and a cup of tableware 1514. The structure 1513 containing the magnets does not have to be embedded across the entire bottom surface; it may be embedded scattered across the bottom surface of the dishware 1504 or the sleeve 1516 that holds the dishware, or it may be embedded in a horseshoe shape when viewed from above, or it may be configured in an annular shape as shown in Figure 24 (see the shape of the magnet 1513 shown by the dotted line in the plan view of Figure 25). The N and S poles of the magnetic material may be configured to be magnetized in the depth direction, if the direction from the top surface to the bottom surface is called the depth direction, so that the N and S poles are oriented, or the N and S poles may be oriented so that they are magnetized in the radial direction of the disc in the plane of the top plate 1504.

[0135] In one modified embodiment 1500, the top plate 1504 is covered with a metal material 1515 that includes a metal material containing iron or a magnetic stainless steel member on its upper surface 1505 side. However, even if the metal material 1515 that includes iron or a magnetic stainless steel member is not covered, the member 1515 that includes iron or a magnetic stainless steel member may be attached to at least a part of the upper surface 1505 of the top plate 1504 (not shown).

[0136] Furthermore, in embodiment 1500, as shown in Figure 26, the control of the magnetic force used in the standing-style serving system 1520 may also be configured as follows. In the configuration according to the present invention, the tabletop 1504 of the standing table 1501 includes, at least a part thereof, a coil member 1535 for an electromagnet and an electromagnet control device 1536 for controlling the current to the coil, and the electromagnet control device 1536, which is supplied with DC power via a support structure 1537 (see Figures 23 and 25) of a DC power module including a battery or rechargeable battery 1510, controls the repulsive force of the electromagnetic force generated by the electromagnet including the magnet 1513 of the tableware 1514 and the coil member 1535, and controls the attractive force between the tableware 1514 and the standing table 1501 by canceling out the attractive force due to the magnetic force acting between the metal material 1515 of the standing table 1501 and the magnet 1513 of the tableware 1514 and the repulsive force due to the magnetic force acting between the magnet 1513 of the tableware 1514 and the electromagnetic force, thereby providing a standing table 1501. With the configuration described herein, the attractive force generated by the cooperation of the tabletop 1504 of the standing table 1501 according to the present invention and the tableware 1514 is partially or completely canceled out by the repulsive force generated by the control of the electromagnet including the coil member 1535, which opens up further possibilities for the present invention to become more effective. For example, when it is undesirable for an attractive force to act by the cooperation of the tabletop 1504 of the standing table 1501 and the tableware 1514, for example, when placing the tableware 1514 on the standing table 1501, or when moving the tableware 1514 on the standing table 1501, or when removing the tableware 1514 from the standing table 1501, the electromagnet control device 1536 can be used to cancel out the attractive force by the magnet with the repulsive force of the electromagnet, providing the effect of enabling gentler placement, movement, and removal of tableware.

[0137] As shown in Figure 26, the pillar 1503 including the boss portion 1522 is integrally joined with the top plate 1504, and as shown in Figure 23, an internal cavity with a bottom facing downward is drilled at the upper end of the pillar 1503, and a support structure 1537 for a DC power module including a battery or rechargeable battery 1510 is disposed inside therein, and when the battery or rechargeable battery 1510 is loaded into the support structure 1537 the DC power module becomes capable of supplying power to the electrical components of the standing table 1501. The standing table 1501 according to the present invention shown in Figures 23 to 26 is characterized in that the support structure 1537 for a DC power module for supplying power to the electrical components of the standing table 1501 is housed in the single pillar 1503.

[0138] Furthermore, the magnetic force used in the standing-style serving system 1520 is preferably configured as follows. In the configuration according to the present invention, the tableware 1514 is a cup or glass that should hold liquid, and the magnetic force generated between the tableware 1514 and a magnet 1513 integrated via a sleeve 1516, and a top plate 1504 covered with a metal material 1515 including iron or a magnetic stainless steel member, is such that when the cup or glass 1514 is filled to about 80% with liquid, even if the top plate 1504 is suddenly moved horizontally to the point where the liquid should spill, the cup or glass will remain held in the position it was placed on by the horizontal movement of the top plate 1504. The standing-style serving system 1520 discloses a suitable standing-style serving system 1520 that, with respect to the magnetic force between the tabletop 1504 and the tableware 1514, ensures that no abnormalities occur in the use of cups or glasses under normal operating conditions. The configuration of the present invention allows for the quantitative determination of the appropriate magnetic force to be generated, thereby more reliably preventing cups or glasses from slipping and tipping over. Here, 50% of a sufficient predetermined magnetic force may be provided by the magnetic force generated between the magnet 1513, which is integrated with the tableware 1514 via the sleeve 1516, and the top plate 1504, which is covered with a metal material 1515 including iron or a magnetic stainless steel member. The remaining 50% may be provided by the electromagnet coil member 1535 shown in Figure 26 and the electromagnet control device 1536 for controlling the current to the coil. The electromagnet control device 1536 receives a DC power supply via a support structure 1537 of a DC power module including a battery or rechargeable battery 1510, and controls the electromagnet control device 1536 so that an attractive force acts between the magnet 1513 embedded in the bottom of the sleeve 1516 holding the tableware 1514 and the electromagnetic force generated by the electromagnet including the coil member 1535, thereby providing a sufficient predetermined magnetic force. By dividing the work in this way, the coil member 1535 for the electromagnet and the electromagnet control device 1536 for controlling the current to the coil can be miniaturized, and the required power consumption can also be reduced, thus providing a more energy-efficient configuration.

[0139] Furthermore, in the standing-style serving system 1520 according to the embodiment described herein, the tableware 1514 is a cup or glass that should hold liquid, and the magnetic force generated between the tableware 1514 and the magnet 1513 embedded in the sleeve 1516 that holds the tableware 1514, the top plate 1504 covered with a metal material 1515 including iron or a magnetic stainless steel member, is configured to generate a predetermined magnetic force sufficient to prevent the cup or glass from moving relative to the top plate 1504 even when the top plate 1504 is tilted to the extent that the liquid would spill out when the cup or glass is 80% full of liquid. The standing-style serving system 1520 discloses herein a suitable standing-style serving system 1520 that, with respect to the attractive force between the top plate 1504 and the tableware 1514, does not cause any abnormalities in the use of the cup or glass under conditions that would normally be used. The configuration described in this invention allows for the quantitative determination of the appropriate magnetic force to be generated, and more reliably prevents cups or glasses from slipping and tipping over to the required extent.

[0140] As described above, several embodiments of a standing buffet table have been described, characterized in that tableware is attracted to the tabletop by magnetic force. However, the standing buffet tables described herein may also be further configured to have markings on the top surface of the tabletop that, when viewed from above, should be identifiable as multiple sections. The effect of the markings on the top surface of the tabletop that should be identifiable as multiple sections, as described above, is that since the top surface of the standing buffet table has markings that should be identifiable as multiple sections, each participant can easily remember the position of their tableware relative to the markings. Recalling memories It goes without saying that this contributes to preventing the mixing of tableware and also allows us to enjoy the effect of suppressing the spread of infectious diseases.

[0141] In this case, the markings may be a standing table characterized by a configuration that includes linear grooves or linear protrusions provided on the upper surface of the tabletop, or a configuration in which the upper surface of the tabletop is identified by coloring each of the sections, or a configuration in which the upper surface of the tabletop is identified by coloring each of the sections, or a configuration in which the upper surface of the tabletop includes a step and includes wall surfaces adjacent to the upper and lower surfaces of the step, or a configuration in which the sections are formed by reinforcing ribs extending vertically upward from the upper surface of the tabletop, or a configuration that includes at least two of these configurations, and the sections formed by the upright wall surfaces formed by the stepped surface formed by the step may also be recessed surfaces, and the effect of each marking to be identified in these multiple sections is that each participant can easily remember the position of the tableware they place in relation to the markings, Recalling memories It goes without saying that this can help prevent the mixing of tableware and thus have the effect of suppressing the spread of infectious diseases.

[0142] The tabletop of the standing-style serving system according to the present invention, as described above, may be a disc, as shown in each figure. A disc is easy to handle when moving, and because it has no corners, it also reduces the risk of contact when moving.

[0143] Next, with reference to Figure 27, an additional embodiment 2300 of the standing table 2301 according to the present invention will be described. Figure 27 is a schematic perspective view of the standing table 2301 from above. The standing table 2301 according to the additional embodiment 2300 of the present invention has a plurality of legs 2302 that are adjacent to the floor surface A and movable via casters 2309, A single pillar 2303 is joined to the leg 2302 and supported upward relative to the floor surface A, The top plate 2304 is horizontally supported by the pillar 2303, A standing table 2301 is disclosed, characterized in that it has a top plate 2304 and is provided with at least one connector 2306 configured to engage with other members on the edge 2305 of the top plate 2304.

[0144] There are various configurations for how the coupler 2306 is connected to the top plate 2304, but preferably, as shown in Figure 27, a groove 2360 is provided along the outer circumference of the edge 2305 of the top plate 2304, and the coupler 2306 is engaged with the groove. If we refer to the direction along the outer circumference of the edge 2305 of the top plate 2304 as the longitudinal direction L, and the direction perpendicular to the longitudinal direction vertically as the width direction D, then the groove 2360 is formed to be wide towards the center of the top plate 2304, and the cylindrical head portion of the connector 2306 of the connecting portion 2350 has a larger diameter than the opening width of the groove 2306 at the outer circumference of the edge 2305, and the connecting portion 2350 is engaged while being restrained to move freely along the longitudinal direction L of the groove within the groove 2360, and in this way the connector 2306 of the connecting portion 2350 is configured to be able to engage with the opening of the groove 2360. As shown in Figure 27, a maintenance spot 2370 is provided to position the coupler 2306 into the groove 2360 of the connecting section 2350. The head of the connecting section 2350 can be fed from the maintenance spot 2370 into the groove 2360. A notch may be provided in a part of the edge 2305 of the tabletop 2304 of the standing table 2301, which is called the maintenance spot 2370, so that the head of the coupler 2306 of the connecting section 2350 can be used not only when it is manufactured but also for subsequent additions or repairs / replacements during maintenance. In this case, it is preferable to insert a plug (not shown in Figure 27; 2471 in Figure 28 corresponds to this) into the maintenance spot 2370 when not being used for maintenance. By inserting the desired number of connecting sections 2350 into the groove 2360 from the maintenance spot, the desired connection of standing tables 2301 can be formed by connecting the couplers to each other.

[0145] Thus, the standing buffet table 2301 is configured to be dynamically connectable to other tables or auxiliary members via the connecting section 2350. When the standing buffet table 2301 is used at a party venue, it can be dynamically connected in a free layout, allowing for flexible grouping of participants. This flexibility allows for groupings of several people to over ten people, and in some cases, participants themselves can dynamically change the layout at the venue. Furthermore, the ability to freely set up groupings of two or three people to over ten people in a single venue is convenient for the venue manager. For example, at a class reunion party, when arranging tables by class, it is possible to allocate tables to classes with only two or three people, or to create a larger table for a class with over ten participants. There is no need to keep tables of various sizes in stock. By connecting multiple standing buffet tables 2301 on the day, five standing buffet tables 2301 can be connected to immediately provide a table for ten people. By using rod materials with connecting parts of the same specifications as 2350, multiple connected standing tables 2301 can be configured in various assembly shapes via connections with auxiliary members, enabling a wide variety of table arrangements.

[0146] Furthermore, the effects of the connection described herein also apply to the following standing table configuration, which has already been explained in detail: a plurality of legs adjacent to the floor surface that can move freely, A single pillar is attached to the leg and supported upward relative to the floor surface, The tabletop is horizontally supported by the pillar, A standing table having a top surface that, when viewed from above in a plan view, has markings on the top surface that indicate the top surface of the top surface should be divided into multiple sections, If a configuration is added to the edge of the tabletop in which at least one connector configured to engage with other members is provided, it goes without saying that the standing buffet table will also produce the effects described in the previous paragraph. Furthermore, variations in the configuration of standing buffet table connections that will be described in detail below will also produce the effects of the invention provided by the markings on the top surface of the standing buffet table in this paragraph, namely, because the top surface of the standing buffet table has markings that should be identified as multiple sections, each participant can easily remember the position of the tableware they place in relation to the markings. Recalling memories This system helps prevent the mixing of tableware and has the added benefit of suppressing the spread of infectious diseases. Furthermore, the combined effect of connecting standing tables ensures a more reliable, comfortable, and safer dining environment.

[0147] Next, there are multiple legs that are adjacent to the floor and can move freely, A single pillar is attached to the leg and supported upward relative to the floor surface, The tabletop is horizontally supported by the pillar, In a standing-only dining table characterized by having a support structure for a DC power module including a battery or rechargeable battery, the standing-only dining table is further characterized by having at least one connector configured to engage with other members on the edge of the tabletop. Needless to say, the effects described in the previous paragraph will also be produced. Furthermore, variations in the configuration of connecting standing-only dining tables, which will be described in detail below, will also be able to utilize the electrical components described in this paragraph. The effects of connecting standing-only dining tables will be superimposed on the effects of the invention provided by the support structure for the DC power module of the standing-only dining table, thus providing a more reliable and comfortable dining environment.

[0148] Next, with reference to Figure 28, an embodiment 2400 of the standing buffet table 2401 according to the present invention will be described. Figure 28 is a schematic perspective view of the standing buffet table 2401 from above. Embodiment 2400 discloses a configuration that is advantageous in that multiple standing buffet tables 2401 can be connected, and the configuration of the standing buffet tables can be flexibly and easily changed according to the situation at various party venues. In Figure 28, at the edge 2405 of the tabletop 2404 of the standing buffet table 2401, a connector rail 2407 is embedded along the outer peripheral vertical surface of the tabletop 2404 to form a groove along the outer circumference of the edge 2405 of the tabletop 2404 (the "connector rail 2407" is also simply referred to as "rail 2407"), and here it is referred to as "rail" because, as already explained, the groove of the rail 2407 has a groove A cylindrical runner 2408, having a head portion wider than the groove opening 2431, is rotatably engaged with the rail 2407 around a vertical axis and is configured to slide in the longitudinal direction L of the groove (hereafter, the direction along the outer circumference of the top plate 2404 of the rail 2407 will be referred to as the longitudinal direction L). The coupler 2409 is engaged to move freely in the longitudinal direction of the groove, so the member in which the groove is formed will be referred to as the rail 2407. In Figure 28, the groove opening 2431 is shown on the edge 2405 of the top plate 2404.A runner 2408, configured to move freely along the outer vertical surface of the tabletop 2404 along the rail 2407 of one standing table 2401, has a through hole 2410 at its tip. A ring-shaped coupler 2409 is engaged with this through hole, and similarly, another ring-shaped coupler 2409 is engaged with a cylindrical runner 2408 engaged with the rail 2407 of another standing table 2401. A connecting pin 2451 is passed through both of these, and each ring-shaped coupler 2409 is passed through the connecting pin 2451 which has a head portion. A connecting plug 2452 is connected from the opposite end of the head portion to prevent the ring portion of the coupler 2409, which is engaged with the cylindrical portion of the connecting pin 2451, from falling out of the cylindrical portion. Disclosed is a standing table 2401 configured such that two opposing standing tables 2401 can engage with each other so that two couplers 2409 can be connected, by fitting into the cylindrical portion of the pin 2451 and being sandwiched between the head portion of the connecting pin 2451 and the connecting plug 2452. Thus, the ring portions of the two couplers 2409 are axially restrained in the cylindrical portion of the connecting pin 2451. In this way, a rail 2407 embedded and fixed in the top plate 2404, a runner 2408 that engages with the rail 2407 so as to be able to move freely in the longitudinal direction L, a coupler 2409 whose ring portion engages with the runner 2408 via a through hole 2410, and the head portion of the connecting pin 2451 that passes through the ring portions of the two couplers 2409 and being sandwiched between the connecting plug 2452. In the connecting portion 2450 of the standing table 2401, the runner 2408, which engages with the rail 2407 and is configured to slide freely along the rail 2407, engages with the coupler 2409. When the runner 2408 moves along the rail 2407 so as to be able to travel around the outer vertical surface of the edge 2405 of the tabletop 2404, the coupler 2409 can also travel along the rail 2407 so as to be able to travel around the outer vertical surface of the edge 2405 of the tabletop 2404. Therefore, when two standing tables 2401 are to be connected, there are no restrictions on the position of the connecting portion 2450, which consists of the runner 2408 and the coupler 2409, on the outer vertical surface.On the other hand, when three standing tables 2401, each having a disc-shaped top plate 2404 of the same diameter, are to be connected, the position of the connecting portion 2450, which consists of runners 2408 and connectors 2409, on the outer vertical surface is constrained to a predetermined position where the centers of the top plates of the standing tables 2401 form an equilateral triangle in plan view. However, the connecting portion 2450, which is connected to the runner 2408 of each standing table 2401, is constrained to a position that is 120 degrees relative to the center of the top plate, and can freely rotate and move along the rail 2407 around the center of the top plate 2404 together with the runner 2408. Therefore, even though the sliding rotation position of the rail 2407 of the runner 2408, which is a component of the connecting portion 2450, differs depending on the number of standing tables 2401 to be connected, the connecting portion 2450 can slide freely to this predetermined position. Then, by passing the connecting pin 2451 through the connecting ring 2409 of each of the two connectors, the two connectors 2409 are successfully engaged with each other, and once the connection of the other set of connectors 2409 is also completed, the connection of the standing tables 2401 is established by the constraint of the three connection points, and the connection of the three standing tables 2401 is rigidly completed. In this way, with the circumferential position of the outer vertical surface as a constraint condition, the number of standing tables 2401 can be automatically determined whether it is three, four, or five, and flexible configuration changes are made without requiring any special additional processing or assembly work on site, thus disclosing a connection configuration for standing tables 2401 that makes it possible to easily connect multiple standing tables 2401. Here, the rail 2407 may be made of a metal material that is smooth and resistant to wear, the runner 2408 may be made of a plastic resin material such as nylon resin or polyacetal resin that has excellent wear resistance, and the ring-shaped part of the coupler 2409 may be a ring-shaped metal fitting, and the ring shape is not limited to an annular shape, but may be a closed shape, or a rectangular metal fitting.

[0149] As shown in Figure 28, maintenance spots 2470 are provided for adding or replacing runners 2408, and a notch may be provided in the rail 2407 at a portion of the edge 2405 of the tabletop 2404 of the standing table 2401. In this case, the maintenance spot 2470 can be fitted with a plug 2471 when not performing maintenance to prevent the runner 2408 from falling off the rail 2407. That is, the rail 2407 may be provided with opposing starting and ending portions, and the gap distance between the starting and ending portions is sufficient to allow the head portion of the runner 2408, which engages with the rail 2407, to be inserted into the groove or to retrieve the runner 2408. Alternatively, the standing table may be provided characterized in that a plug 2471 for preventing the runner 2408 from detaching is fitted into the starting and ending portions of the rail 2407. Plug 2471 prevents runner 2408 from detaching, ensuring more stable operation, and provides the convenience of being able to remove the plug and replace runner 2480 when necessary.

[0150] The standing table 2401 disclosed in Figure 28 has a plurality of legs 2402 that are adjacent to each other and can be moved via casters 2419 to the floor surface A, A single pillar 2403 is joined to the leg 2402 and supported upward relative to the floor surface A, The top plate 2404 is horizontally supported by the pillar 2403, A standing buffet table 2401 is disclosed, characterized in that it has a top plate 2404 with markings 2413 on the upper surface 2405 that are to be identified as a plurality of sections 2411, 2412 in a plan view from above, and is further characterized in that at least one connector 2409 is provided on the edge 2405 of the top plate 2404 that is configured to be engageable with other members, and a configuration that enables connection according to the present invention is also disclosed for the standing buffet table 2401 characterized in that it has markings 2413 that are to be identified as a plurality of sections 2411, 2412, and the effect of each of these markings that are to be identified as a plurality of sections is that each participant can easily remember the position of the tableware they place in relation to the marking, Recalling memories This helps prevent the mixing of tableware and has the effect of suppressing the spread of infectious diseases. The linking function allows for the dynamic and free arrangement of standing tables 2401, and participants can be freely configured into grouping units. This offers flexibility, allowing for grouping units of a few people to more than ten people, and in some cases, participants themselves can dynamically change the layout at the venue. Furthermore, the ability to freely set up grouping units of two or three people to more than ten people in a single venue is a benefit for venue managers, as is the effect of dynamic table linking. As the number of participants in a grouping unit increases through linking, the need to identify one's own private area by partitioning increases.

[0151] Looking back at Figure 28, Multiple legs 2402 are adjacent to the floor surface A and are movable via casters 2419, A single pillar 2403 is joined to the leg 2402 and supported upward relative to the floor surface A, The top plate 2404 is horizontally supported by the pillar 2403, A standing table 2401 is disclosed, characterized in that it has a support structure 2427 for a DC power module including a battery or rechargeable battery, and the edge 2405 of the tabletop 2404 is provided with at least one connector 2409 configured to engage with other members, and a configuration that enables connection according to the present invention is also disclosed for a standing table 2401 that makes electrical equipment usable by the support structure 2427 for the DC power module. The standing buffet table according to the present invention has a support structure 2427 for a DC power module including a battery or rechargeable battery. By attaching the DC power module including a battery or rechargeable battery to the support structure 2427, power can be supplied to various electrical accessories of the standing buffet table 2401 without providing a general power cord. Users can move the standing buffet table 2401 according to the present invention, which is configured to be freely movable on the floor, providing a dining environment in which each participant can freely move to their desired position within the party venue. Furthermore, the linking function allows for the dynamic and free layout of the standing buffet tables, enabling the free configuration of grouping units for participants. This system offers flexibility, allowing for group sizes ranging from a few people to over ten, and even enabling participants to dynamically change the layout on-site. Furthermore, it allows for flexible grouping of participants from two or three to over ten people within a single venue, providing convenience for venue managers through dynamic table linking. These two effects create a synergistic benefit: if at least one of the linked tables includes an electromagnetic induction heater (a type of electrical component), it provides a designated area for food requiring warming, making it a desirable variation.

[0152] Next, with reference to Figures 29-31, the usage configuration when two standing tables 2401 according to the present invention are connected will be described in more detail. Figure 29 is a schematic plan view from above showing two standing tables 2401 facing each other left and right, connected via the connectors 2409 of the connecting parts 2450 of each standing table 2401. Figure 30 is a schematic cross-sectional view of the tabletop 2404 in a side view when two standing tables 2401 are facing each other left and right, at the point W-W in Figure 29. Figure 31 is a schematic exploded perspective view from below of the connecting part of two standing tables to illustrate a usage configuration when two preferred standing tables according to one embodiment of the present invention are connected.

[0153] In Figure 29, two standing tables 2401 are shown facing each other left and right. At the connecting section 2450 of each table, the ring portions of the couplers 2409 are connected by a connecting pin 2451, which penetrates from front to back on the paper. The couplers 2409 are connected so that they can rotate freely around the connecting pin 2451 by a plug (not shown in Figure 29). In Figure 30, two standing tables 2401 are shown facing each other left and right. A side view shows the configuration in which the head portion of the connecting pin 2451 is housed in a groove 2430 formed in the interior of the rail 2407, and the configuration in which the ring-shaped portion of the coupler 2409 engages with the cylindrical portion of the connecting pin 2451. In Figure 30, the groove 2430 formed in the interior of the rail 2407 is filled in black to represent the inner wall surface of the interior of the rail 2407, and does not represent coloring as in the other drawings. Figure 31 is a schematic, exploded perspective view from below of the connection section 2450 of two standing tables in use when the two standing tables are connected, illustrating the connection structure of the connection section 2450 of Figure 30. In the connection section 2450 of each standing table 2401, the connecting pin 2451 passes through the ring sections of the couplers 2409 shown on the left and right in Figure 31 from top to bottom, and the vertical movement range is constrained by the plug 2452, so that the coupler 2409 cannot be disengaged from the engagement state with the connecting pin 2451, and the movement of both couplers 2409 is constrained within the cylindrical length of the connecting pin 2451 so that they can rotate freely around the connecting pin 2451. The coupler 2409 is ring-shaped and rotatably engages with the rail 2407 of the tabletop 2404 via a through hole 2410 provided in the runner 2408, which engages with the rail 2407 embedded in the outer vertical surface of the edge 2405 of the tabletop 2404. The connecting portion 2450 of the two opposing standing tables 2401 is configured such that the rails 2407 of the two standing tables 2401 are connected to each other via the coupler 2409 and runner 2408 by a connecting pin 2451.In other words, the connecting portion 2450 of the standing table 2401 engages with a rail 2407 embedded in the tabletop 2404, and the connecting pin 2451 is restrained by the head portion of a connecting pin 2451 that can pass through the ring of a ring-shaped connector 2409 which is rotatably engaged with a through hole provided in a runner 2408 that is engaged so as to be able to rotate around the outer vertical surface of the edge portion 2405 of the tabletop 2404 along the rail 2407, and a plug 2452 that is fitted to close the tip portion of the connecting pin after it has passed through the ring, and the standing table 2401 is disclosed in which two standing tables 2401 are engaged by connecting pins 2501 that pass through the ring portions of each other's connectors 2409.

[0154] The tabletop of the standing table according to the present invention, as described above, may be a disc. A disc is convenient because it is easy to handle when moving, and because it has no corners, the risk of contact during movement is reduced. Furthermore, if rails are provided along the outer circumference of the disc, the connecting part can be connected to other tables anywhere along the circumference, providing greater flexibility in configuration and making it a more preferable configuration.

[0155] The edges of the tabletop of the standing table according to the present invention, as described above, may be colored. The edges of the standing table are easily visible in a side view, and the coloring makes it easier to identify the table when viewed from a distance. If the table is identifiable within a venue, users can identify the table with their own designated area, providing a safer eating environment and a more suitable standing table. In Figure 38, shown later, the outer vertical surface of the edge 3209 of the tabletop 3204 of the standing table 3201 is colored 3219 (e.g., red), 3220 (e.g., blue), and 3221 (e.g., yellow). The coloring of the edge 3209 makes it easier to identify the table when viewed from a distance. If the table is identifiable within a venue, users can identify the table with their own designated area, providing a safer eating environment and a more suitable standing table.

[0156] Thus, looking back at the standing table 2401 according to an additional embodiment 2400 of the present invention, Multiple legs 2402 are adjacent to the floor surface A and are movable via casters 2409, A single pillar 2403 is joined to the leg 2402 and supported upward relative to the floor surface A, The top plate 2404 is horizontally supported by the pillar 2403, A standing table 2401 is characterized by having at least one connector 2409 that is configured to engage with other members along the outer vertical surface of the edge 2405 of the tabletop 2404, A standing table 2401 is disclosed, in which the rail 2407 has a groove structure provided on the outer vertical surface of the top plate 2404 along the circumferential direction L, and the groove has a cross-sectional shape such as a C-shape or a square shape, with an opening 2431 connecting to the outside of the groove 2430, which is narrower than the width of the groove portion 2430 in the inner part of the rail, and the cylindrical runner 2408 has a head portion for housing in the groove 2430 in the inner part of the rail, the head portion having a diameter larger than the opening 2431 of the groove, the head portion is housed in the groove portion 2430 in the inner part of the rail 2407 and is engaged so as to be rotatable around an axis perpendicular to the longitudinal direction L of the rail 2407, and a ring-shaped connector 2409 is engaged in a through hole 2410 provided at the tip of the runner 2408.

[0157] Furthermore, the overall length of the runner 2408 of the standing table 2401 is longer than the groove depth from the bottom surface of the groove 2430 (the surface furthest from the opening) to the opening 2431, thereby preventing the runner 2408 from falling into the groove 2430 and facilitating handling. The rail may be made of a metal material as shown in Figure 30 and manufactured by fitting the metal rail into an outer groove processed on the edge of the tabletop, or a tabletop with grooves may be made by cutting an annular groove into a disc that is divided into upper and lower halves and joining the upper and lower discs, and then joining this to a single pillar, or a thin metal sheet may be attached to the surface of the groove, or the tabletop with grooves may be manufactured by molding it using a plastic resin material (not shown).

[0158] Here, a standing-only table 2401 may be provided, characterized in that the rail 2407 includes opposing starting and ending portions, and the gap between the starting and ending portions is configured to be wide enough to allow the runner 2408 to be inserted into or retrieved from the groove 2430. Alternatively, a standing-only table may be provided, characterized in that plugs 2471 for preventing the runner 2408 from detaching are configured to be fitted into the starting and ending portions of the rail 2407 (see Figure 28). The plugs 2471 prevent the runner 2408 from detaching, ensuring more stable operation, and providing the convenience of being able to remove the plug and replace the runner 2408 when necessary.

[0159] Thus, if we consider the connected standing tables as a group, and refer to the various forms of standing tables disclosed so far, the components invented for constructing standing tables, the standing table groups that are connected to form various islands in a standing reception venue, and the group of components and parts that are configured in the venue as sets of multiple table groups, with each of these various standing table groups being a single unit, then here, Multiple legs 2402 are adjacent to the floor surface A and are movable, A single pillar 2403 is joined to the leg 2402 and supported upward relative to the floor surface A, A standing table system comprising a standing table 2401 having a top plate 2404 horizontally supported by the pillar 2403, and at least one connector 2409 configured to engage with other members on the edge 2405 of the top plate 2404, wherein at least two standing tables 2401 are connected to each other by the connector 2409 to form at least one table group, wherein one standing table 2401 is connected by a cylindrical connecting pin 2451 having a head portion and a cylindrical portion The standing table system is provided characterized in that the two standing tables 2409 are connected via the connecting pin 2451, with the ring portion of the connector 2409 passing through the ring-shaped portion of the connector 2409, the ring-shaped portions of the two connectors 2409 being held in place by the cylindrical portion, the other end of the head portion being fitted into the cylindrical portion, and the ring-shaped portions of the two connectors 2409 being sandwiched between the head portion of the connecting pin 2451 and the plug 2452, thereby connecting the two connectors 2409 to each other via the connecting pin 2451. This configuration enables easy connection, making it possible to easily provide the standing table system at the venue.

[0160] Here, the venue, as in the previous paragraph, refers to a standing reception venue, a standing reception table system, or standing reception tables if the purpose is a standing reception. However, the uses of the present invention are not limited to these, and it is useful for venues where people gather ad hoc for the purpose of eating and drinking, business negotiations, socializing, or entertainment, and when people gather in ad hoc groups of ad hoc numbers to enjoy themselves. It is suitable for a variety of situations, such as standing reception venues, exhibition meeting venues, travel lounges, and casino venues.

[0161] Now, in relation to the usage modes of the standing table system according to the present invention described above, as another embodiment, a connection method for connecting two standing tables is further disclosed below. That is, this will be explained with reference to the flowchart of each step of preferred connection method M1 for a standing table 2401 according to one embodiment of the present invention, shown in Figure 41. That is, when connecting one standing table 2401 to another standing table 2401 using a standing table 2401 characterized by having a plurality of legs 2402 adjacent to the floor surface A so as to be movable, a single pillar 2403 joined to the legs 2402 and supported upward relative to the floor surface A, and a top plate 2404 horizontally supported by the pillar 2403, and having at least one connector 2409 configured to be engageable with other members at the edge 2405 of the top plate 2404, <Step (S1) of aligning the ring-shaped parts of both couplers> The first step (S1) is to align the ring 2409 that engages with the runner 2408 of one of the standing tables 2401 with the ring-shaped portion of the connector 2409 that engages with the runner 2408 of the other standing table 2401. Subsequently, step (S2) is performed. <Step (S2) of passing the connecting pin 2451 through the two ring sections> Step (S2) is performed following step (S1), in which a cylindrical connecting pin 2451 having a head portion and a cylindrical portion is passed through two ring portions 2409 provided on one standing table 2401 and the other standing table 2401, thereby holding the ring-shaped portions of the two connectors 2409 in place with the cylindrical portions.

The method M1 for connecting standing buffet tables 2401 according to the present invention, which includes the three steps (S1) to (S3) described above, discloses a method M1 for connecting standing buffet tables 2401 in a dynamically free layout by connecting them. This provides flexibility, allowing for the free configuration of participant grouping units, from a few people to a dozen or so people, and in some cases, allowing participants themselves to dynamically change the layout at the venue. Furthermore, it provides the convenience of being able to freely arrange table groups in a variety of ways in one venue, from two or three people to a dozen or so people, and also benefits the venue manager from the effect of dynamic table connection. The present invention provides a simple method for connecting standing tables, which allows for easy connection even in venues where standing tables are used, through a concise method.

[0162] In relation to the usage modes of the standing table system according to the present invention described above, the following connection method for connecting two standing tables is disclosed. That is, this will be explained with reference to the flowchart of each step of preferred connection method M2 for standing tables 2401 according to one embodiment of the present invention, shown in Figure 42. A standing table 2401 comprising a plurality of legs 2402 adjacent to a floor surface A so as to be movable, a single pillar 2403 joined to the legs 2402 and supported upward relative to the floor surface A, and a tabletop 2404 horizontally supported by the pillar 2403, wherein the tabletop 2404 is provided with at least one connector 2409 configured to engage with other members, wherein the standing table 2401 further comprises a rail 2407 embedded on the outer peripheral vertical surface of the tabletop 2404 at the edge 2405, and the connector 2409 configured to engage with a runner 2408 that engages with the rail 2407, wherein the rail 2407 is a grooved rail 2407 provided along the circumferential direction L on the outer peripheral vertical surface of the tabletop 2404, and The groove has a cross-sectional shape in which the opening 2431 connecting to the outside of the groove 2430 portion of the inner part of the rail is configured to be narrower than the width of the groove 2430 portion of the inner part, and the cylindrical runner 2408 having a head portion for being housed in the groove portion 2430 has a diameter larger than the width of the opening 2431 of the groove 2430, and the head portion is housed in the groove 2430 portion of the inner part of the rail 2407, and the cylindrical runner 2408 is engaged so as to be rotatable about an axis perpendicular to the longitudinal direction L of the rail 240c7, and a ring-shaped connector 2409 is engaged in a through hole 2410 provided at the tip of the runner 2408, and when it is necessary to connect one of the standing tables 2401 to another standing table 2401, the method for connecting standing tables 2401 according to the present invention is a method in which the following steps are performed in stages. <Preparation step (PS) to rotate each runner on the rails and move the couplers on both sides to opposing positions> First, as a preparatory step for coupling, a step (PS) is performed in which the ring-shaped portion of the coupler 2409 that engages with the runner 2408 of one standing table 2401 and the ring-shaped portion of the coupler 2409 that engages with the runner 2408 of the other standing table 2401 are moved to opposing positions by rotating the respective runners 2408 on the rail 2407. <Step (S1) of aligning the ring-shaped parts of both couplers> The first step (S1) is to align the ring-shaped portion of the connector 2409 that engages with the runner 2408 of one of the standing tables 2401 with the ring-shaped portion of the connector 2409 that engages with the runner 2408 of the other standing table 2401.

Subsequently, the next step (S3) is performed. <Step (S3) of fitting the plug 2452 onto the connecting pin 2451 and joining the two ring portions 2409> The final step following step (S2) is step (S3), in which the plug 2452 is fitted from the other end of the head portion of the connecting pin 2451 to the cylindrical portion, and the ring-shaped portions of the two connectors 2409 are sandwiched between the head portion of the connecting pin 2451 and the plug 2452. The method M2 for connecting standing buffet tables 2401 according to the present invention, which includes the above steps (PS) and steps (S1) to (S3), discloses a method for connecting standing buffet tables 2401 in a dynamically free layout by connecting them. This allows for the free configuration of participant grouping units, from a few people to a dozen or so people, and in some cases, allows participants themselves to dynamically change the layout at the venue, demonstrating flexibility. Furthermore, it provides the convenience of being able to freely set up participant grouping units from two or three people to a dozen or so people in a single venue, and also benefits venue managers by providing the effect of dynamic table connection. In addition, the method M2 further provides a method for connecting standing buffet tables in which the runner is freely rotated by sliding it on a rail by the preparation step (PS), making it easier to align the ring-shaped parts of both connectors.

[0163] Various standing table systems can be provided by connecting standing table systems equipped with connectors using the above-described connection method, based on the various standing table systems according to the present invention described in detail above.

[0164] Thus, a standing table system 2530 including a standing table 2501 according to the present invention is provided in an additional embodiment 2500. An embodiment 2500 of the standing table 2501 according to the present invention will be described with reference to Figures 32 and 33. Figure 32 is a schematic perspective view from above of a preferred three-table standing system 2530 according to one embodiment of the present invention. Figure 33 is a schematic plan view from above of a preferred three-table standing system 2530 according to one embodiment of the present invention. The connecting portion 2550 is positioned at an optimal location on the outer vertical surface together with a runner that is slidably engaged with a rail, so that three standing tables 2501 are connected to each other via the connecting portion 2550, and a standing table system 2530 is disclosed in which imaginary lines connecting the centers of adjacent tabletops form an equilateral triangle.

[0165] Alternatively, a standing table system 2630 including a standing table 2601 according to the present invention is disclosed in an additional embodiment 2600. A further additional embodiment 2600 of the standing table 2601 according to the present invention is described with reference to Figures 34 and 35. Figure 34 is a schematic perspective view from above of a preferred four-table standing table system 2630 according to one embodiment of the present invention. Figure 35 is a schematic plan view from above of a preferred four-table standing table system 2630 according to one embodiment of the present invention. A standing table system 2630 is disclosed, which includes a table group in which four standing tables 2601 are connected to each other via connecting parts 2650, and the standing tables 2601 are arranged such that the imaginary lines connecting the centers of adjacent tabletops form a square, and the connecting parts 2650 are positioned at an optimal position on the outer vertical surface together with runners that are slidably engaged with rails.

[0166] Alternatively, a standing table system 2730 including a standing table 2701 according to the present invention is disclosed in an additional embodiment 2700. An additional embodiment 2700 of the standing table system 2730 according to the present invention will be described with reference to Figures 36 and 37. Figure 36 is a schematic perspective view from above of a preferred five-unit standing table system 2730 according to one embodiment of the present invention. Figure 37 is a schematic plan view from above of a preferred five-unit standing table system 2730 according to one embodiment of the present invention. A standing table system 2730 is disclosed, which includes a table group in which five standing tables 2701 are connected to each other via connecting parts 2750, and the standing tables 2701 are arranged such that the imaginary lines connecting the centers of adjacent tabletops form a regular pentagon, and the connecting parts 2750 are positioned at an optimal position on the outer vertical surface together with runners that are slidably engaged with rails.

[0167] As in one embodiment 2700, when five standing tables 2701 are connected to each other by a connector, the five standing tables 2701 spread out in the shape of a cherry blossom with a central gap. If a dealer is placed in the central gap, it is suitable for a game room. The ability to provide such diverse usage forms is a characteristic of the standing table system provided by the present invention.

[0168] Various standing reception party systems, which include multiple standing reception tables connected to each other by couplers, can be provided by combining the various variations of standing reception tables described above in various ways. That is, Standing tables used in a standing reception system may be configured so that a standing table with a colored tabletop can be identified among multiple standing tables by the coloring of the top surface of the tabletop. The coloring of the tabletop may be provided by coloring the edges of the tabletop.

[0169] Furthermore, a standing buffet table in a standing buffet party system may be characterized by having markings on the top surface of the tabletop that, when viewed from above in a plan view, indicate that the top surface of the tabletop is divided into multiple sections.

[0170] Furthermore, the standing tables in a standing party system are tables that are meant to be shared by multiple people, and the markings may be linear grooves or linear protrusions provided on the top surface of the tabletop.

[0171] Furthermore, the signage for the standing buffet table in a standing buffet system may be on the wall adjacent to the upper and lower surfaces of the stepped portion, with the top surface of the tabletop having a stepped design.

[0172] Furthermore, in a standing buffet party system, the top surface of the tabletop may have markings that, when viewed from above, indicate that the top surface of the tabletop is divided into multiple sections, and these markings may be identified by coloring the top surface of the tabletop according to each section. By coloring, the sections on a single standing buffet table, i.e., the dedicated areas for each participant on that table, are identified, and by placing each person's tableware in these areas, the mixing of tableware with others is prevented, and a standing buffet party system that provides a safer eating environment is disclosed here.

[0173] Next, a standing table system 3230 including a standing table 3201 according to the present invention is disclosed in an additional embodiment 3200. An additional embodiment 3200 is described with reference to Figures 38 and 39. Figure 38 is a schematic perspective view from above showing three islands of standing tables 3201 forming separate islands. Figure 39 is a schematic perspective view from above showing a configuration in which one island, or table group, is formed from three standing tables 3201. In the standing buffet party system 3230, in the color space formed by the colors 3211 (e.g., black), 3212 (e.g., white) of the top surface 3205 of the tabletop 3204 and the colors 3219 (e.g., red), 3220 (e.g., blue), 3221 (e.g., yellow) of the edge 3209, sections 3206 and 3207 on the top surface 3205 of the tabletop 3204 are represented by the colors 3216, 3217, and 3219, or 3206 (achromatic), so that their colors can be identified within the standing buffet party system 3230. Therefore, in the color space, if we refer to them as Table (1), Table (2), and Table (3) from left to right in Figure 38, the color pairs (color 1, color 2) in the color space of each section are: Table (1) Section 3206 (achromatic 3206, red 3219), Section 3207 (white 3212, red 3219) Table (2) Section 3206 (Achromatic 3206, Blue 3220), Section 3207 (Black 3211, Blue 3220) Table (3) Section 3206 (Achromatic 3206, Yellow 3221), Section 3207 (Black 3211, Yellow 3221) Therefore, since each participant's color pair is unique in the color space, the coloring of the standing buffet party system 3230 is configured so that by remembering the color pair as a combination, one can identify their own dedicated area from among multiple tables. For example, if (achromatic 3206, blue 3220) is remembered, then among the three tables, the table with this two-color pair will be identified as table (2), and it will be necessary to identify the area on the top surface of the tabletop that is either achromatic or blue. Even if the tables within the table group are rearranged or moved slightly, one can easily identify their own dedicated area table and area on the table by the color pair. Furthermore, even though there are only two colors, there is no confusion as to whether the table edge 3209 is achromatic, which area on the table is achromatic, or whether the table edge 3209 is blue, which area on the table is blue. Thus, the standing buffet party system 3230 is disclosed here, which provides a more reliable and safe eating environment in terms of preventing contact infection. In the usage embodiment shown in Figure 39, where a table group consisting of three standing tables 3201 is formed from three standing tables 3201, the definition of the standing table system configuration based on color pairs is significant because each section is uniquely identified within the group by the color pair.

[0174] Thus, a standing table system is provided, characterized in that the upper surface 3205 of the tabletop 3204 of the standing table 3201 has markings to be identified by color in a plan view from above, and each section and edge of the standing table 3201 is colored in a color space configured to be identified by a combination of colors of a color pair formed by the coloring of the tabletop 3204 and the coloring of the edge 3209.

[0175] Therefore, focusing on the color space of the standing reception table system 3230 at a standing reception venue, a standing reception table system is provided which is characterized by being managed in a closed manner within a table group. In this system, the color space is defined by a combination of colors of a color pair formed by the coloring of the tabletop and the coloring of the edges, and the coloring is configured such that the sections are defined by color pairs within a standing reception table group.

[0176] Furthermore, a standing buffet table system 3240 may be provided, characterized in that a single color space is managed as a unified color space across table groups within the venue. In this case, for example, if the color of one's designated area is achromatic and the color of the table edge is blue, then by remembering (achromatic, blue), the table and area with this two-color pair can be identified within the standing buffet table system of the entire party venue. Even if the tables are moved or the layout is slightly altered across table groups within the standing buffet table system of the venue, one's designated area table and the area on the table can be reliably identified within the standing buffet table system of the venue (see Figure 38), thus providing a reliably safe eating environment in terms of preventing contact infection. On the other hand, pairs may be identified by permutations rather than by color combinations. In this case, (the section is colored achromatic, the table edge is colored blue) and (the section is colored blue, the table edge is achromatic) are distinguished, making it possible to reduce the color variations by half and to make the color differences stand out more in the primary color system. This is a more convenient configuration when dividing the table into three or more sections (not shown).

[0177] Next, another preferred use of one embodiment of the standing table system according to the present invention will be described using Figure 40. Figure 40 is a schematic perspective view of a usage configuration in which a standing table system consisting of five tables connected in a row is pulled in the direction of the arrow. The standing table 3301 shown here can be used in restaurants that provide self-service for serving food, and when used by a person with a physical disability, without the need for support from other able-bodied people, for example, if a standing table 3301 is provided at the end of the serving counter, the person can move around the restaurant on the standing table 3301 and eat in their preferred location. Even after finishing their meal, they can leave the standing table 3301 in place and signal completion of their meal by setting a flag, and the restaurant staff can then clear the table. In this case, as long as a straight passageway to the table clearing area is secured, the restaurant staff can clear multiple used standing tables. As shown in Figure 40, the tables 3301 can be connected in a row to each other by, for example, five connecting units 3350, and can be pulled and moved simultaneously in the direction of the arrows. This allows for efficient clearing of tables in self-service restaurants and provides a suitable dining environment suitable for providing standing-style cafeteria service even in self-service restaurants. This provides a suitable dining environment where even people with physical disabilities can use self-service restaurants without hesitation. Here, the standing-style tables 3301 are not specially adjusted for the standing-style table system 3330, and any of the standing-style tables introduced here that are equipped with connectors can be used. However, standing-style tables connected in the middle should be equipped with at least two connectors.

[0178] As described above, several embodiments of connectable standing tables have been explained, but as already stated, the standing tables described herein may also be further configured to have markings on the top surface of the tabletop that, when viewed from above, should be identifiable as multiple sections. Furthermore, as described above, the effect of the markings on the top surface of the tabletop that should be identifiable as multiple sections is that, because the standing table has markings on the top surface of the tabletop that should be identifiable as multiple sections, each participant can easily remember the position of their tableware relative to the markings. Recalling memories It goes without saying that this contributes to preventing the mixing of tableware and helps to suppress the spread of infectious diseases, and the linking function allows for the dynamic and free arrangement of standing tables, enabling the free configuration of participant grouping units, from a few people to a dozen or so people, and in some cases, allowing participants themselves to dynamically change the layout at the venue, demonstrating flexibility. Furthermore, the ability to freely set up participant grouping units from two or three people to a dozen or so people in a single venue, along with the benefit of dynamic table linking which is convenient for venue managers, can be enjoyed, and as already mentioned, as the number of participants in a grouping unit increases through linking, the need to identify one's own private area by partitioning increases.

[0179] Furthermore, as already stated here, the markings are not limited to those made by color, but may also be a standing buffet table characterized by a configuration that includes linear grooves or linear protrusions provided on the top surface of the tabletop, or a configuration in which the top surface of the tabletop is identified by coloring each section, or a configuration in which the top surface of the tabletop is identified by coloring each section, or a configuration in which the top surface of the tabletop includes steps and includes wall surfaces adjacent to the upper and lower surfaces of the steps, or a configuration in which sections are formed by reinforcing ribs extending vertically upward from the top surface of the tabletop, or includes at least two of these configurations, and the sections formed by the upright wall surfaces formed by the stepped surfaces formed by the steps may also be recessed surfaces, and the effect of each marking to be identified in these multiple sections is that each participant can easily remember the position of the tableware they place in relation to the markings, Recalling memories It goes without saying that this can help prevent the mixing of tableware and thus have the effect of suppressing the spread of infectious diseases.

[0180] Conversely, multiple legs that are adjacent to the floor and can move freely, A single pillar is attached to the leg and supported upward relative to the floor surface, The tabletop is horizontally supported by the pillar, A standing buffet table having a top surface that, in a plan view from above, has markings on the top surface of the top surface that indicate the top surface of the top surface should be identifiable as being divided into multiple sections, and the standing buffet table having at least one connector configured to engage with other members at the edge of the top surface, the same flexibility in connection variations provided by a standing buffet table, in particular, where a rail is embedded on the outer vertical surface of the top surface at the edge of the top surface, and the connector is configured to engage with a runner that engages with the rail, will also apply. Needless to say, the same connection effects of the standing buffet tables disclosed herein will be obtained, and the use of a dedicated area for each participant provided by the markings will undoubtedly provide a safer and more comfortable eating environment.

[0181] Similarly, multiple legs are adjacent to the floor surface and are movable, A single pillar is attached to the leg and supported upward relative to the floor surface, The tabletop is horizontally supported by the pillar, A standing-only table characterized by having a support structure for a DC power module including a battery or rechargeable battery, further characterized by having at least one connector configured to engage with other members at the edge of the tabletop, also applies to the variations in configuration of standing-only tables described in detail above, in particular the flexibility of connection variations provided by a standing-only table further configured in which a rail is embedded on the outer vertical surface of the tabletop at the edge of the tabletop, and the connector is configured to engage with a runner that engages with the rail. It is certain that the effects of connecting similar standing-only tables disclosed herein, in particular the effects of standing-only tables equipped with electrical components, can be provided to a group of connected tables, thereby providing a more reliable and comfortable dining environment.

With this configuration of the present invention, the attractive force generated by the cooperation between the tabletop of the standing table according to the present invention and the tableware is controlled by the electromagnet, which has the advantage of opening up further avenues for the present invention to become more effective. For example, when the standing table is moved, a magnetic field is generated by the current flowing through the coil, the tableware is stabilized by the attractive force due to magnetic field lines when necessary, and during eating, the electromagnetic force is dissipated via the electromagnet control device to prevent the attractive force from interfering with eating, thereby providing a more comfortable eating environment.

[0196] As a reference embodiment for achieving the above objective, in an embodiment in which an additional configuration is added to the standing table described in the seventh paragraph of this section, "Means for Solving the Problem," a standing table is provided characterized in that a metal material including an iron or magnetic stainless steel member is attached or embedded to at least a part of the upper surface of the tabletop of the standing table that faces the bottom surface of the tableware or sleeve for holding the tableware to which a magnet is attached or embedded, so that the tableware is attracted to the tabletop by magnetic force. With this configuration of the present invention, the cooperation between the tabletop of the standing table according to the present invention and the tableware exerts an effect that increases the attractive force, and there is an advantage that the present invention will have further room to produce even greater effects.

[0197] The standing table described in the preceding paragraph is provided, characterized in that the tabletop of the standing table includes, at least a part thereof, a coil member for an electromagnet and an electromagnet control device for controlling the current to the coil, and the electromagnet control device controls the repulsive force between the magnet of the tableware and the electromagnet, thereby controlling the attractive force between the tableware and the metal material of the standing table and the magnet by canceling out the attractive force due to the magnetic force acting between them and the repulsive force. With the configuration described in the present invention, the attractive force generated by the cooperation between the tabletop of the standing table according to the present invention and the tableware is partially or completely canceled out by the repulsive force generated by the control of the electromagnet, which has the advantage of opening up further avenues for the present invention to become more effective. For example, when you don't want an attractive force to act between the tabletop of a standing-style dining table and the tableware, such as when serving tableware on the table, moving tableware on the table, or clearing tableware from the table, an electromagnet control device can be used to counteract the attractive force of magnets with the repulsive force of electromagnets, enabling gentler serving, moving, and clearing of tableware.
