Description

Technical Field

[0001] The present invention relates to a frame kitchen and an assembly method thereof.

Background Art

[0002] Conventionally, cabinet-type kitchens for housing such as single-family houses and condominiums have been mainstream. Also, such cabinet-type kitchens are generally prefabricated in factories or the like, and the completed kitchens are transported to single-family houses and installed at predetermined locations. However, in recent years, kitchens have become larger in size, and when installing a completed cabinet-type kitchen, it is difficult to pass through the entrance or stairs of a single-family house, and there has also been a situation where the kitchen or the house is damaged during the move-in process. Moreover, in residential areas, the roads connecting to single-family houses are narrow, and trucks or cranes with lifting devices cannot enter, and there is also a problem that they have to be transported manually. Also, in the renovation of apartment houses or other multi-family dwellings, whether it can be loaded onto an elevator has become a major key to the move-in process, and various problems have occurred during the move-in process.

[0003] In order to solve such problems, a knockdown-type kitchen that transports parts and assembles them locally has also been proposed. For example, Patent Document 1 discloses a method for assembling a knockdown-type storage cabinet including a step of attaching an upper back panel to a wall, a step of attaching an upper box to the wall such that the lower end thereof contacts the upper end of the upper back panel, a step of attaching a lower back panel to the wall at an interval from the upper back panel, a step of attaching a lower box so as to cover a part of the upper back panel and a part of the lower back panel, and a step of attaching side plates to the upper box and the lower box so as to cover from the upper end of the upper box to the lower end of the lower back panel (see Claim 1 of the claims of Patent Document 1, paragraphs

[0021] ~

[0027] of the specification, FIG. 1 of the drawings, etc.).

[0004] The assembly method for storage cabinets described in Patent Document 1 allows panels and parts to be packaged together in a compact state, transported, and assembled on-site. However, because the parts are in the form of cabinets, there are constraints on dimensions and other specifications, making it difficult to adjust the dimensions to match the layout of a residential kitchen. Furthermore, cabinet-type kitchens tend to be relatively expensive.

[0005] On the other hand, in recent years, frame kitchens have been proposed that prioritize simple functionality and design, consisting of a minimum number of parts such as frames and shelves. However, because frame kitchens are based on a frame made of assembled metal pipes and consist of a minimum number of parts, there is a problem that when assembled on-site, there are many connecting parts, and the assembly work takes a long time. In addition, when joining the support members and horizontal members (crossbars), if the screws are not lightly tightened while someone holds the frame in place for a preliminary assembly, the assembled structure will be warped and the shelves will not be able to be attached, which requires two people to work on, and thus the cost of assembly work has also increased.

[Modes for carrying out the invention]

[0018] Hereinafter, one embodiment for implementing the frame kitchen and heating / cooling method according to the present invention will be described in detail with reference to the drawings.

[0019] [First Embodiment] <Frame Kitchen> First, a frame kitchen 1 according to the first embodiment of the present invention (hereinafter also simply referred to as frame kitchen 1) will be described using Figures 1 to 8. Figure 1 is a perspective view showing the completed frame kitchen 1 according to the first embodiment of the present invention, and Figure 2 is a perspective view showing the support structure 2 with the countertop 3 of the frame kitchen 1 according to the first embodiment removed. Figure 3 is an exploded perspective view showing the configuration of each part of the support structure 2 of the frame kitchen 1 according to the first embodiment.

[0020] The frame kitchen 1 according to this embodiment is a kitchen based on a frame made of connected metal pipes, and consists of a support structure 2 made of a frame that supports the kitchen, a countertop 3 placed on the support structure 2, and a stainless steel sink 4 installed on the countertop 3.

[0021] (Tabletop) The countertop 3 is a component based on a kitchen counter 30 made of wooden planks. As shown in Figure 1, the kitchen counter 30 has a sink hole 31, which is a rectangular hole for setting the sink 4 described later, and a stove hole 32, which is a rectangular hole for setting a stove (not shown). In addition, a faucet hole 33, which is a circular through-hole for installing a faucet, is drilled on the back side near the center of the sink hole 31. It goes without saying that the kitchen counter 30 is not limited to wooden planks, but may be formed from other planks such as stainless steel, artificial marble, or stone.

[0022] ((Support structure)) As shown in Figures 2 and 3, the support structure 2 consists of a pair of left and right freestanding units 5, 5 and a rectangular connecting frame 6 in plan view that connects the freestanding units to each other. Depending on the kitchen layout, it is preferable to attach a side panel 7 for concealment to the external side of the freestanding unit 5 where a side wall is not installed.

[0023] (Self-supporting unit) The self-supporting unit 5 is a self-supporting unit assembled in a rectangular shape in plan view from four metal pipe supports 50 and multiple horizontal bars 51, 52 that connect the upper ends of these supports 50 horizontally.

[0024] The horizontal bars are as follows: the first horizontal bar 51 connects the upper ends of the support columns 50 in the longitudinal direction on the front and back sides; the second horizontal bar 52 connects the upper ends of the support columns 50 in the short direction on the left and right sides; and the third horizontal bar 53 connects the middle sections of the support columns 50 in three stages in the short direction on the sides.

[0025] Furthermore, as shown in Figures 1 to 3, a front panel 54 is attached to the top of the support column 50 and the front side of the first horizontal bar 51 to conceal the stove installed in the stove hole 32 or the piping portion of the sink 4 in the sink hole 31.

[0026] (Connecting frame) The connecting frame 6 is a rectangular frame in plan view, formed by welding together angle members 60 made of three steel materials and a steel flat bar 61 on the front side.

[0027] <Connection point between the freestanding unit and the connecting frame> Next, the details of the connection between the self-supporting unit 5 and the connecting frame 6 will be explained using Figures 4 to 6. Figure 4(a) is a partially enlarged perspective view showing the side of the self-supporting unit 5 on the side connected to the connecting frame 6, and Figure 4(b) is a partially enlarged perspective view showing a further enlargement of the area around the screw hole 52a. Figure 5(a) is a partially enlarged view showing the connection between the self-supporting unit 5 and the connecting frame 6, and Figure 5(b) is a partially enlarged view showing a further enlargement of the connection between the self-supporting unit 5 and the connecting frame 6. Finally, Figure 6(a) is an exploded perspective view showing the components of the connection between the self-supporting unit 5 and the connecting frame 6, and Figure 6(b) is an enlarged exploded perspective view showing a further enlargement of the connection between the self-supporting unit 5 and the connecting frame 6.

[0028] As shown in Figures 5 and 6, the side surface 60a of the connecting angle material 60, which is connected to the self-supporting unit 5 of the connecting frame 6, has a notch 60b formed therein for inserting and fastening a screw S1, which will be described later.

[0029] On the other hand, as shown in Figure 4, a screw hole 52a is drilled in the side surface of the second crossbar 52 on the connecting side, which is connected to the connecting frame 6 of the self-supporting unit 5, for screw fastening with a screw S1. As shown in Figures 5 and 6, the screw S1 is fixed to this screw hole 52a. Therefore, as will be described later, it becomes easy and quick for one person to connect the self-supporting units 5 with the connecting frame 6. Although the example shows the use of a screw S1 in the screw hole 52a, a button-shaped projection or rivet with a predetermined gap can be used instead of a screw S1, as they can be fastened in a similar manner.

[0030] <Spacing material for self-supporting units> Next, the spacing member 9 of the self-supporting unit 5 will be explained using Figures 7 to 9. Figure 7 is a partially enlarged perspective view mainly showing the spacing member 9 attached to the lower part of the self-supporting unit 5. Figure 8 is a partially enlarged perspective view showing the joint between the shelf support plate 8 and the spacing member 9 before joining, and Figure 9 is a partially enlarged perspective view showing the joint between the shelf support plate 8 and the spacing member 9 when joined.

[0031] As shown in Figure 7, a pair of left and right shelf support plates 8, 8 are attached to the inside of the second and third horizontal bars 53 from the top, which are stretched between the support columns 50, 50 along the short side of the self-supporting unit 5, on which shelves are placed.

[0032] Furthermore, as shown in Figure 7, a spacing member 9 made of a U-shaped steel material is installed between these shelf support plates 8, 8 to connect them and maintain the spacing between them. As shown in Figure 8, a locking claw 9a, 9a is formed at both ends in the longitudinal direction of this spacing member 9, which is used to hook onto the shelf support plates 8.

[0033] On the other hand, the shelf support plate 8 has a rectangular through hole 8a into which the locking claws 9a are inserted. As a result, the locking claws 9a at both ends of the spacing material 9 are locked together by the through holes 8a of the pair of shelf support plates 8, 8, preventing the lower ends of the third crossbars 53 and the support columns 50 joined to these third crossbars 53 from spreading or narrowing, allowing the shelf board to be placed and fixed quickly and easily.

[0034] In the center of the shelf support plate 8, a connecting recess 81 is formed, which is recessed by the thickness of the spacing member 9, and a through hole 8a is drilled on the outside of this connecting recess 81. As a result, as shown in Figure 9, by simply fitting the latching claws 9a of the spacing member 9 into the through hole 8a from above, the spacing member 9 maintains the spacing between the third horizontal bars 53 and the support columns 50 joined to these third horizontal bars 53 at a predetermined distance, and the upper surface of the spacing member 9 and the upper surface of the shelf support plate 8 become flush, allowing the shelf board to be easily and quickly placed on the shelf support plate 8 without having to perform any processing such as counterboring on the shelf board to be placed on it.

[0035] Furthermore, screw holes 8b for screwing and fixing the shelf board are drilled in the connecting recess 81, and screw holes 9b for screwing and fixing the shelf board are also drilled on the inside of the retaining claws 9a near both ends of the spacing member 9. These screw holes 8b and screw holes 9b overlap and communicate simply by fitting the retaining claws 9a of the spacing member 9 into the through holes 8a of the shelf support plate 8 from above, making it easy to screw in the shelf board from below.

[0036] <How to assemble a frame kitchen> Next, using Figures 10 to 15, a method for assembling the frame kitchen 1 according to the first embodiment of the present invention will be described.

[0037] (Installation process of the self-supporting unit) Figure 10 is a process diagram illustrating the freestanding unit installation process of the assembly method for a frame kitchen according to the first embodiment. As shown in Figure 10, in the assembly method for a frame kitchen according to the first embodiment, first, a freestanding unit installation process is performed in which a pair of left and right freestanding units 5, 5 are installed in predetermined positions.

[0038] However, as will be explained later, the spacing between the freestanding units 5,5 is determined simply by fitting the connecting frame 6 into place. Therefore, in this process, one freestanding unit 5 is installed along the side wall, and the other freestanding unit 5 is installed at an approximate distance, and there is no need to precisely measure and install them using a scale or the like.

[0039] (Screw installation process) Figure 11 is a process diagram illustrating the screw fastening process in the assembly method of the frame kitchen according to the first embodiment, Figure 12(a) is a magnified view showing the vicinity of the screw S1 in the connection part between the freestanding unit 5 and the connecting frame 6, and Figure 12(b) is a further magnified view showing one of the screws S1. As shown in Figures 11 and 12, in the assembly method of the frame kitchen according to the first embodiment, the next step is to install the screw S1, which is a fastening material, into the screw hole 52a drilled in the side surface of the second horizontal bar 52.

[0040] However, in this step, the screw S1 is not screwed completely into the screw hole 52a, but rather installed with a gap so that the screw head of the screw S1 does not come into contact with the second crossbar 52. This is to leave space for inserting the connecting frame 6 in the next step. As mentioned above, instead of the screw S1, a button-shaped or other projection that forms a predetermined gap with the second crossbar 52 may be provided.

[0041] (Connecting frame installation process) Figure 13 is a process diagram illustrating the connecting frame installation step of the assembly method for the frame kitchen according to the first embodiment, and Figure 14 is a perspective view showing the state in which the freestanding units 5, 5 are connected to each other by the connecting frame 6. As shown in Figures 13 and 14, in the assembly method for the frame kitchen according to the first embodiment, the next step is to install the connecting frame 6 by inserting it into the gap between the screw head of the screw S1 installed in the previous step and the second horizontal bar 52.

[0042] Specifically, the screw S1 is inserted through a notch 60b formed on the side surface 60a of the angle material 60 of the connecting frame 6 into the gap between the screw head of the screw S1 and the second crossbar 52, and then fastened. In this way, the spacing between the self-supporting units 5,5 is defined and their positioning is determined simply by fitting the connecting frame 6 into the gap between the screw head of the screw S1 and the second crossbar 52. Therefore, the support structure 2 can be assembled by one person without the need for two people as in the conventional method, thereby reducing the cost of assembly work. After that, as shown in Figure 14, the screw S1 is further tightened to connect and fix the self-supporting units 5 together with the connecting frame 6.

[0043] (Spacing material installation process) Figure 15 is a perspective view showing the state after the spacing material installation step of the frame kitchen assembly method according to the first embodiment has been performed, and the spacing material 9 has been installed between the shelf support plates 8, 8. As shown in Figures 7 to 9 and Figure 15, in the frame kitchen assembly method according to the first embodiment, the next step is to install the spacing material 9 by bridging it between the shelf support plates 8, 8.

[0044] Specifically, in this step, the locking claws 9a of the spacing member 9 are fitted into the through holes 8a of the shelf support plate 8 from above. In this step, the spacing member 9 maintains the spacing between the third horizontal bars 53 and the support columns 50 joined to these third horizontal bars 53 at a predetermined interval. Moreover, as mentioned above, a connecting recess 81 is formed in the center of the shelf support plate 8, where the part to which the spacing member 9 is joined is recessed by the thickness of the spacing member 9. Therefore, simply by fitting the locking claws 9a of the spacing member 9 into the through holes 8a of the shelf support plate 8, the upper surface of the spacing member 9 and the upper surface of the shelf support plate 8 become flush. For this reason, the shelf board can be easily and quickly placed on the shelf support plate 8 without having to perform any processing such as counterboring on the shelf board to be placed in the next step.

[0045] Furthermore, as mentioned above, simply by fitting the retaining claws 9a of the spacing member 9 into the through holes 8a of the shelf support plate 8 from above, the positions of the screw holes 8b and 9b overlap and communicate. This makes it easy to fasten the screws to secure the shelf board in the next step.

[0046] (Shelf fixing process) Subsequently, in the assembly method of the frame kitchen according to the first embodiment, a wooden shelf board is placed on the shelf support plate 8 and the spacing material 9, and the shelf board is fixed in place using tapping screws through the screw holes 8b and screw holes 9b that overlapped and communicated in the previous step. Upon completion of this step, the assembly of the frame kitchen 1 according to the assembly method of the frame kitchen according to the first embodiment is completed.

[0047] According to the frame kitchen 1 and the assembly method for the frame kitchen according to the first embodiment of the present invention described above, the spacing between the self-supporting units 5, 5 is determined and positioned simply by fitting the connecting frame 6 into the gap between the screw head of the screw S1 and the second horizontal bar 52. Therefore, the support structure 2 can be assembled by one person without the need for two people as in the conventional method, thereby reducing the cost of assembly work.

[0048] Furthermore, according to the frame kitchen 1 and the assembly method of the frame kitchen according to the first embodiment, the spacing material 9 maintains the spacing between the third horizontal bars 53 and the support columns 50 joined to these third horizontal bars 53 at a predetermined interval, so that even with one person working, the support structure 2 can be assembled accurately in a short time without distortion.

[0049] Furthermore, according to the frame kitchen 1 and the assembly method of the frame kitchen according to the first embodiment, a connecting recess 81 is formed in the center of the shelf support plate 8, where the portion to which the spacing material 9 is joined is recessed by the thickness of the spacing material 9. Therefore, by simply fitting the latching claws 9a of the spacing material 9 into the through holes 8a of the shelf support plate 8, the upper surface of the spacing material 9 and the upper surface of the shelf support plate 8 become flush, and the shelf board B1 can be easily and quickly placed on the shelf support plate 8 without having to perform any processing such as counterboring on the shelf board B1.

[0050] [Second Embodiment] <Frame Kitchen> First, the frame kitchen 1' (hereinafter also simply referred to as frame kitchen 1') according to the second embodiment of the present invention will be described using Figures 16 to 24. Figure 16 is a perspective view showing the completed frame kitchen 1' according to the second embodiment of the present invention, and Figure 17 is a perspective view showing the support structure 2' with the countertop 3' of the frame kitchen 1' according to the second embodiment removed. Figure 18 is an exploded perspective view showing the configuration of each part of the support structure 2' of the frame kitchen 1' according to the second embodiment.

[0051] The frame kitchen 1' according to this embodiment is a kitchen based on a frame made of connected metal pipes, similar to the frame kitchen 1 described above. It consists of a support structure 2' made of a frame that supports the kitchen, a countertop 3' placed on the support structure 2', and a stainless steel sink 4 installed on the countertop 3'. Components identical to those in the frame kitchen 1 according to the first embodiment are denoted by the same reference numerals, and detailed descriptions are omitted.

[0052] (Tabletop) The countertop 3' is a component based on the kitchen counter 30' made of wooden planks, and is longer in depth than the aforementioned kitchen counter 30 by the amount of space for piping at the back. As shown in Figure 16, this kitchen counter 30' has a sink hole 31', which is a rectangular hole for setting the sink 4, and a stove hole 32', which is a rectangular hole for setting a stove (not shown), similar to the aforementioned kitchen counter 30. In addition, a faucet hole 33', which is a circular through-hole for installing a faucet, is drilled on the back side near the center of the sink hole 31'. It goes without saying that the kitchen counter 30' is not limited to wooden planks, but may also be made from other planks such as stainless steel, artificial marble, or stone.

[0053] ((Support structure)) As shown in Figures 17 and 18, the support structure 2' consists of a central self-supporting unit 5', side panels 6' made of metal pipe material, and a rectangular connecting panel 7' in front view that connects the self-supporting unit 5' and the side panels 6'. Reference numeral 10' denotes a connecting bar 10' made of strip steel plate.

[0054] (Self-supporting unit) The self-supporting unit 5' is a self-supporting unit assembled in a rectangular shape in plan view from four metal pipe supports 50', a first horizontal bar 51' connecting the upper ends of these supports 50' in the left-right direction, a second horizontal bar 52' ​​connecting the upper ends of these supports 50' in the depth direction, an intermediate panel 53' connecting the middle sections of the second horizontal bar 52', and a third horizontal bar 54' connecting the middle sections of the supports 50' in three rows in the shorter direction on the side. The intermediate panel 53' is a panel with a rectangular frame made of metal pipes to which a cover plate such as perforated metal is attached.

[0055] (Side panel) The side panel 6' is composed of a pair of support columns 60' made of metal pipe material, an upper rail 61' connecting the upper ends of these support columns 60', a lower rail 62' connecting the lower ends of these support columns 60', a vertical rail 63' connecting the middle sections of the upper rail 61' and the lower rail 62', and a middle rail 64' connecting the middle sections of the vertical rail 63' and the support columns 60', and so on. In addition, a privacy panel 65' made of perforated metal is attached to one of the side panels 6' for concealment.

[0056] (Connecting panel) The connecting panel 7' consists of two types of connecting panels: a front panel 71' provided at the front and an intermediate panel 72' installed on the same plane as the aforementioned intermediate panel 53'. The front panel 71' is a panel intended to conceal the piping portion of the stove installed in the stove hole 32' or the sink 4 in the sink hole 31', while the intermediate panel 72', like the intermediate panel 53', is a panel intended to conceal the piping portion of the water supply and drainage of the frame kitchen 1'.

[0057] Both the front panel 71' and the intermediate panel 72' are panels in which flat bars are joined together by welding or other means to form a rectangular frame (a horizontally elongated rectangle when viewed from the front), and a concealing panel made of perforated metal or the like is attached to it.

[0058] <Connection point between the freestanding unit and side panel and the connecting panel> Next, Figures 19 to 21 will be used to describe in detail the connection between the freestanding unit 5' and the side panel 6' and the connecting panel 7'. Figure 19(a) is a partially enlarged perspective view showing the side of the freestanding unit 5' that connects to the connecting panel 7', and Figure 19(b) is a partially enlarged perspective view showing the side of the side of the side of the side of the side of the connecting panel 6' that connects to the connecting panel 7'. Figure 20(a) is a partially enlarged view showing the connection between the freestanding unit 5' and the connecting panel 7', and Figure 20(b) is a partially enlarged view showing an enlarged view of the connection between the side panel 6' and the connecting panel 7'. Finally, Figure 21(a) is an exploded perspective view showing the components of the connection between the freestanding unit 5' and the connecting panel 7', and Figure 21(b) is an exploded perspective view showing the components of the connection between the side panel 6' and the connecting panel 7'.

[0059] As shown in Figure 19(a), a screw hole 53a' is drilled in the side surface of the connecting intermediate panel 53' that connects to the connecting panel 7' of the self-supporting unit 5', for screwing in and fixing a fastening material, a screw S1. As shown in Figures 20(a) and 21(a), the fastening material, the screw S1, is fixed in this screw hole 53a'.

[0060] Furthermore, as shown in Figure 19(b), screw holes 63a' are drilled in the side surface of the connecting vertical bar 63' that connects the side panel 6' to the connecting panel 7', and as shown in Figures 20(a) and 21(a), the screws S1 are fixed to these screw holes 63a'.

[0061] On the other hand, as shown in Figures 21(a) and 21(b), L-shaped notches 72b' are formed on the side surface 72a' of the connecting flat bar that connects to the self-supporting unit 5' of the intermediate panel 72', which is the connecting panel 7', and on the side surface 72a' of the connecting flat bar that connects to the side panel 6' of the intermediate panel 72', respectively, for which the aforementioned screws S1 are inserted and fastened.

[0062] Therefore, as described later, it becomes easy and quick for one person to connect the self-supporting unit 5' and the side panel 6' with the connecting panel 7'. Although the example shows the case where screws S1 are attached to the screw holes 53a' and 63a', instead of screws S1, protrusions such as button-shaped projections or rivets with a predetermined gap may be provided. This is because they can be fastened in the same way.

[0063] <Maintaining distance between the freestanding unit and the side panel> Next, Figures 22 to 24 will be used to describe the spacing member 9' that maintains the distance between the freestanding unit 5' and the side panel 6'. Figure 22 is a partially enlarged perspective view mainly showing the spacing member 9' that spans the lower parts of the freestanding unit 5' and the side panel 6'. Figure 23 is a partially enlarged perspective view showing the joint between the shelf support plate 8' attached to the lower rail 62' of the side panel 6' and the spacing member 9' before joining, and Figure 24 is a partially enlarged perspective view showing the joint between the shelf support plate 8' attached to the lower rail 62' of the side panel 6' and the spacing member 9' when they are joined.

[0064] As shown in Figure 22, a pair of left and right shelf support plates 8', 8' for supporting shelf board B1 are attached to the outside of the second and third horizontal bars 54' from the top, which are spanned between the support columns 50', 50' of the freestanding unit 5'. Similarly, shelf support plates 8', 8' for supporting shelf board B1 are attached to the inside of the bottom bar 62' and middle bar 64' of the side panel 6'.

[0065] Furthermore, as shown in Figure 22, a spacing member 9' made of a U-shaped steel material is installed between these shelf support plates 8', 8' to connect the shelf support plates 8', 8' and maintain the distance between the self-supporting unit 5' and the side panel 6'. As shown in Figure 23, a locking claw 9a', 9a' is formed at both ends in the longitudinal direction of this spacing member 9' to be hooked onto the shelf support plate 8'.

[0066] On the other hand, as shown in Figure 23, the shelf support plate 8' has a rectangular through-hole 8a' into which the locking claws 9a' are inserted. Therefore, the locking claws 9a' at both ends of the spacing material 9' are locked together by the through-holes 8a' of the pair of left and right shelf support plates 8', 8', preventing the gap between the self-supporting unit 5' and the side panel 6' from widening or narrowing, and allowing the shelf board B1 to be placed and fixed easily in a short time.

[0067] Furthermore, a connecting recess 81' is formed in the center of the shelf support plate 8', where the space-holding member 9' is joined, and a through hole 8a' is drilled on the outside of this connecting recess 81'. As a result, as shown in Figure 24, by simply fitting the latching claws 9a' of the space-holding member 9' into the through hole 8a' from above, the space-holding member 9' maintains the distance between the self-supporting unit 5' to which the shelf support plate 8' is attached and the side panel 6' at a predetermined distance. At the same time, the upper surface of the space-holding member 9' and the upper surface of the shelf support plate 8' become flush, allowing the shelf board B1 to be easily and quickly placed on the shelf support plate 8' without requiring any processing such as counterboring on the shelf board B1.

[0068] Furthermore, screw holes 8b' are drilled in the connecting recess 81' for screwing in the shelf board B1, and screw holes 9b' are also drilled inside the retaining claws 9a' near both ends of the spacing member 9' for screwing in the shelf board B1. These screw holes 8b' and screw holes 9b' overlap and communicate simply by fitting the retaining claws 9a' of the spacing member 9' into the through holes 8a' of the shelf support plate 8' from above, making it easy to screw in the shelf board B1 from below.

[0069] <How to assemble a frame kitchen> Next, using Figures 25 to 33, a method for assembling the frame kitchen 1' according to the second embodiment of the present invention will be described.

[0070] (Installation process of the self-supporting unit) Figure 25 is a process diagram illustrating the freestanding unit installation process of the frame kitchen assembly method according to the second embodiment. As shown in Figure 25, in the frame kitchen assembly method according to the second embodiment, first, a freestanding unit installation process is performed in which the central freestanding unit 5' is installed in a predetermined position.

[0071] However, as will be explained later, the distance between the freestanding unit 5' and the side panel 6' is determined simply by fitting the connecting panel 7', so in this process, it is not necessary to take precise measurements with a scale or the like before installation.

[0072] (Screw installation process) Figure 26 is a process diagram illustrating the screw fastening process in the assembly method of the frame kitchen according to the second embodiment, Figure 27(a) is a magnified view showing the vicinity of the screw S1 at the connection portion between the freestanding unit 5' and the connecting panel 7', and Figure 27(b) is a magnified view showing the vicinity of the screw S1 at the connection portion between the side panel 6' and the connecting panel 7'. As shown in Figures 26 and 27, in the assembly method of the frame kitchen according to the second embodiment, the next step is to install screws S1, which are fasteners, into screw holes 53a' and screw holes 63a' drilled in the side surface of the intermediate panel 53' of the freestanding unit 5' and in the vertical ribs 63' of the side panel 6'.

[0073] However, in this process, the screws S1 are not screwed completely into the screw holes 53a' and 63a', but are installed with a gap so that the screw heads of the screws S1 do not come into contact with the intermediate panel 53' or vertical bars 63'. This is to leave space for inserting the connecting panel 7' in the next process. As mentioned above, instead of screws S1, button-shaped protrusions or rivets or other protrusions that form a predetermined gap with the intermediate panel 53' or vertical bars 63' may be provided.

[0074] (Connecting panel installation process) Figure 28 is a process diagram illustrating the process of attaching the intermediate panel 72', which is the connecting panel 7', in the assembly method of the frame kitchen according to the second embodiment. Figure 29 is a perspective view showing the state after the connecting panel attachment process has been performed and the freestanding unit 5' and the side panel 6' are connected by the connecting panel 7'. Figure 30 is a process diagram illustrating the process of attaching the front panel 71', which is the connecting panel 7', in the assembly method of the frame kitchen according to the second embodiment. Figure 31 is an enlarged perspective view showing the state before the front panel 71' is attached in the connecting panel attachment process, with an enlarged view of the joint between the freestanding unit 5' and the connecting panel 7'. Figure 32 is an enlarged perspective view showing the state after the front panel 71' has been attached in the connecting panel attachment process, with an enlarged view of the joint between the freestanding unit 5' and the connecting panel 7'.

[0075] As shown in Figures 28 and 29, in the assembly method of the frame kitchen according to the second embodiment, the next step is to install the connecting panel 7' by inserting it into the gap between the screw head of the screw S1 installed in the previous step and the intermediate panel 53' and the gap between the screw head of the screw S1 and the vertical support 63'.

[0076] Specifically, the screw S1 is inserted through the L-shaped notch 72b' formed on the flat bar side surface 72a' of the intermediate panel 72' and fastened in the gap between the screw head of the screw S1 and the intermediate panel 53', and the screw S1 is also inserted through the L-shaped notch 72b' formed on the side surface 72a' of the intermediate panel 72' and fastened in the gap between the screw head of the screw S1 and the vertical bar 63'.

[0077] Subsequently, as shown in Figures 30 to 32, the screw S1 is inserted through the L-shaped notch 71b' formed in the flat bar side surface 71a' of the front panel 71' into the gap between the screw head of the screw S1 and the intermediate panel 53', and secured in place. At the same time, the screw S1 is inserted through the L-shaped notch 71b' formed in the side surface 71a' of the front panel 71' into the gap between the screw head of the screw S1 and the vertical bar 63', and secured in place. Of course, it goes without saying that the intermediate panel 72' and the front panel 71', which are connecting panels 7', can be installed in either order.

[0078] In this way, the distance between the self-supporting unit 5' and the side panel 6' is defined and positioned simply by fitting the L-shaped notches 71b' and 72b' onto the screw S1. Therefore, the support structure 2' can be assembled by one person without the need for two people as in the conventional method, thereby reducing assembly costs. After that, the screw S1 is further tightened to connect and fix the self-supporting unit 5' and the side panel 6' with the connecting panel 7'.

[0079] Similarly, on the opposite side of the central freestanding unit 5' shown in Figures 28 to 32, the freestanding unit 5' and the side panel 6' are connected and fixed together with the connecting panel 7'.

[0080] (Spacing material installation process) Figure 33 is a perspective view showing the state after the spacing material installation step of the frame kitchen assembly method according to the second embodiment has been performed, and the spacing material 9' has been installed between the shelf support plates 8', 8'. As shown in Figures 22 to 24 and Figure 33, in the frame kitchen assembly method according to the second embodiment, the next step is to install the spacing material 9' by bridging it between the shelf support plates 8', 8'.

[0081] Specifically, in this process, the retaining claws 9a' of the spacing material 9' are fitted into the through holes 8a' of the shelf support plate 8' from above. This process maintains the spacing between the third horizontal bars 54' of the second and third rows of the self-supporting unit 5' to which the shelf support plate 8' is attached, and the bottom bars 62' and middle bars 64' of the side panel 6', thereby maintaining the spacing between the self-supporting unit 5' and the side panel 6'.

[0082] Moreover, as mentioned above, a connecting recess 81' is formed in the center of the shelf support plate 8' where the spacing member 9' is joined, and a through hole 8a' is drilled on the outside of this connecting recess 81'. Therefore, by simply fitting the latching claws 9a' of the spacing member 9' into the through hole 8a' of the shelf support plate 8', the upper surface of the spacing member 9' and the upper surface of the shelf support plate 8' become flush. For this reason, the shelf board B1 to be placed in the next step can be easily and quickly placed on the shelf support plate 8' without having to perform any processing such as counterboring on the shelf board B1.

[0083] Furthermore, as mentioned above, the connecting recess 81' has screw holes 8b' for screwing the shelf board B1 in place, and screw holes 9b' for screwing the shelf board B1 in place are also drilled inside the retaining claws 9a' near both ends of the spacing member 9'. As a result, these screw holes 8b' and screw holes 9b' overlap and communicate simply by fitting the retaining claws 9a' of the spacing member 9' into the through holes 8a' of the shelf support plate 8' from above, making it easy to screw the shelf board B1 in place from below.

[0084] Subsequently, in the assembly method of the frame kitchen according to the second embodiment, other parts such as connecting bars 10' made of strip steel plates are screwed in or fitted together to assemble the support structure 2'.

[0085] (Shelf fixing process) Finally, in the assembly method of the frame kitchen according to the second embodiment, a wooden shelf board B1 is placed on the shelf support plate 8' and the spacing material 9', and the shelf board is fixed in place by screwing it with tapping screws using the screw holes 8b' and 9b' that overlapped and communicated in the previous step. Upon completion of this step, the assembly of the frame kitchen 1 according to the assembly method of the frame kitchen according to the second embodiment is completed.

[0086] According to the frame kitchen 1' and the assembly method for the frame kitchen according to the second embodiment of the present invention described above, the distance between the self-supporting unit 5' and the side panel 6' is defined and positioned simply by fitting the L-shaped notches 71b' and 72b' onto the screws S1. Therefore, the support structure 2' can be assembled by one person without the need for two people, as in the conventional method, thereby reducing the cost of assembly work.

[0087] Furthermore, according to the frame kitchen '1 and the assembly method of the frame kitchen according to the second embodiment, the spacing between the third horizontal bars 54' of the second and third rows of the freestanding unit 5' to which the shelf support plates 8' are attached by the spacing-holding material 9' and the lower bars 62' and middle bars 64' of the side panel 6' is maintained, thereby maintaining the spacing between the freestanding unit 5' and the side panel 6'. As a result, the support structure 2' can be assembled accurately in a short time without distortion, even by one person.

[0088] Furthermore, according to the frame kitchen 1' and the assembly method of the frame kitchen according to the second embodiment, a connecting recess 81' is formed in the center of the shelf support plate 8', where the space-holding member 9' is joined, and the portion recessed by the thickness of the space-holding member 9' is formed. Therefore, by simply fitting the latching claws 9a' of the space-holding member 9' into the through holes 8a' of the shelf support plate 8', the upper surface of the space-holding member 9' and the upper surface of the shelf support plate 8' become flush, and the shelf board B1 can be easily and quickly placed on the shelf support plate 8 without having to perform any processing such as counterboring on the shelf board B1.

[0089] Although the frame kitchens 1,1' and the assembly method of the frame kitchens according to embodiments of the present invention have been described in detail above, the dimensions, materials, etc. of the embodiments described above or illustrated are merely examples of embodiments that have been materialized in carrying out the present invention. Therefore, the technical scope of the present invention should not be interpreted as being limited by these. [Explanation of Symbols]
