Description

The present invention relates to a mounting structure of a wooden top plate for a kitchen.

Conventionally, a structure for attaching a top plate to furniture has been proposed, and there is a method of attaching a wooden top plate while correcting the warp of the top plate (see, for example, Patent Document 1). In addition, there are some that devise a structure so that the top plate itself does not warp (see, for example, Patent Document 2). Further, it is known that the back surface of the table top plate is grooved, one side of an L-shaped angle is inserted, and the table top plate is attached with a wood screw to prevent warpage.

JP-A-2007-222460 JP-A-2002-357

In the above-mentioned conventional technique, the problem is that the top plate itself warps due to its nature, or how to attach the warped top plate, and a solution thereof is presented.

In addition, it is known that wood-based materials absorb a lot of moisture from the end of the wood, but due to the warping nature of the wood-based material, the groove processing on the table top plate is L-shaped by providing grooves in the direction perpendicular to the fiber direction of the wood. Since the angle of the wood is attached, the area of the wood end increases, and in the case of such a structure, caulking is difficult, and when water infiltrates, it tends to accumulate due to surface tension, and it is difficult to dry, so there is a lot of water and moisture. It is counterproductive in places.

Here, a kitchen can be mentioned as a place with a lot of water and humidity, but since wood materials have the property of expanding and contracting according to the moisture content, when using a wood top plate for a system kitchen, the wood top plate expands and contracts. It is necessary to have a mounting structure that prevents the wood top plate from warping by treating the stress generated between the kitchen and the kitchen body due to the occurrence of. In particular, there is an increasing desire in the market to use high-grade solid wood and laminated wood alone for kitchen doors, etc., and it will be necessary to use this for the top plate in the future. However, since the top plate itself cannot be configured so as not to expand and contract by, for example, a combination of plywood and wood materials, a solution by a mounting structure is required.

On the other hand, in the wooden top plate of the conventional frame type kitchen, a round hole penetrating up and down is arranged in a frame in which iron square pipes are assembled in a square shape, and the top plate is placed on it. The top plate was fixed by passing wood screws through the round holes from below. Alternatively, a nut or the like that serves as a receiver was inserted into the top plate and fixed with bolts from below. With such a mounting structure, when the top plate is a solid plate or laminated wood, there is a problem that it expands and contracts due to changes in the water content, the fixed frame is deformed, and the top plate itself is deformed in a wavy manner. It was.

The present invention solves the above-mentioned conventional problems, and when a wooden top plate is used for a system kitchen, the stress generated between the wooden top plate and the kitchen body due to the expansion and contraction of the wooden top plate according to the water content is generated. It provides a mounting structure for a wooden top plate for kitchen, which can be processed to prevent warping or cracking of the wooden top plate, distortion of the frame, and the like.

In order to solve the above problems, the mounting structure of the kitchen wood top plate of the present invention is a mounting structure of the kitchen wood top plate fixed on a plurality of frames, and the wood top plate is the plurality of frames. It is fixed by a fixing member passing through a round hole formed in at least one of the above and a fixing member passing through a long hole in the front-rear direction formed in at least one of the plurality of frames, and is fixed in front of and behind the wooden top plate. It is characterized in that the fixing member passing through the elongated hole moves with expansion and contraction in the direction.

It is also preferable that the plurality of frames include frames arranged with the longitudinal direction as the left-right direction.

It is also preferable that the plurality of frames include frames arranged with the longitudinal direction as the front-rear direction.

Further, it is preferable that the round hole is arranged near the center in the front-rear direction.

Further, it is preferable that the round hole is arranged in the vicinity of the rear in the front-rear direction.

Further, it is preferable that the fiber direction of the wooden top plate is the left-right direction.

It is also preferable that another kitchen element or wall is arranged adjacent to at least one of the left and right sides of the wooden top plate.

Further, it is preferable that a gap is provided between the wooden top plate and another kitchen element or wall adjacent to the wooden top plate, and the sealing material is inserted into the gap.

Further, it is preferable that the frame is subjected to uneven processing.

The "other kitchen elements" include sink worktops and stove worktops (worktops for ordinary stoves that emit flames using gas, as well as worktops for heating equipment such as IH cooking heaters and halogens. .), Which is arranged as a combination of system kitchens. The "front-back direction" is the direction of the depth of the kitchen, and the "left-right direction" is the direction of the width of the kitchen. The side where a person normally stands and works is described as the front, and the back is described as the back.

In the mounting structure of the kitchen wood top plate of the present invention, the kitchen wood top plate is fixed on a plurality of frames. The wooden top plate is fixed by a fixing member that passes through a round hole formed in at least one of a plurality of frames and a fixing member that passes through a long hole in the front-rear direction formed in at least one of the plurality of frames. .. Then, as the wooden top plate expands and contracts in the front-rear direction, the fixing member passing through the elongated hole moves. Therefore, when the wooden top plate expands and contracts according to the water content, the fixing member passing through the round hole does not move, but the fixing member passing through the long hole moves, thereby treating the stress generated with the kitchen body. As a result, it is possible to prevent warping and cracking of the wooden top plate, distortion of the frame, and the like.

Further, when the plurality of frames include frames arranged with the longitudinal direction as the left-right direction, the structure may be such that either a round hole or an elongated hole is formed for each frame in the left-right direction.

Further, when the plurality of frames include a frame arranged with the longitudinal direction as the front-rear direction, the structure may have both round holes and elongated holes formed in the front-rear direction frame.

Further, when the round hole is arranged near the center in the front-rear direction, the fixing member near the center does not move and the fixing member other than the vicinity of the center moves, so that both the extension from the vicinity of the center to the front-rear direction is allowed. By doing so, the length of elongation (stress) can be dispersed.

Further, when the round hole is arranged in the vicinity of the rear in the front-rear direction, the fixing member in the vicinity of the rear does not move and the fixing member other than the vicinity of the rear moves, so that only the extension from the vicinity of the rear to the front is allowed. As a result, it is possible to secure a stretch margin when the rear is a wall or the like.

Further, when the fiber direction of the wood top plate is set to the left-right direction, the direction of the elongated holes can be adjusted to the direction in which the wood top plate is easily expanded and contracted.

When another kitchen element or wall is arranged adjacent to at least one of the left and right sides of the wooden top plate, the other kitchen element or wall is arranged while avoiding the direction in which the wooden top plate easily expands and contracts. be able to.

In addition, if there is a gap between the wooden top plate and other kitchen elements or walls adjacent to it, and a sealing material is inserted in the gap, the wooden top plate will expand and contract slightly in the left-right direction. , It can be dealt with by the gap and the elasticity of the sealing material.

Further, when the frame is unevenly processed, the frame can be made slippery so that the fixing member passing through the elongated hole can be easily moved.

As described above, according to the mounting structure of the wooden top plate for kitchen of the present invention, when the wooden top plate is used for the system kitchen, it is between the wooden top plate and the kitchen body due to the expansion and contraction of the wooden top plate according to the water content. It is possible to prevent warping and cracking of the wooden top plate, distortion of the frame, etc. by treating the stress generated in.

Next, the mounting structure of the wooden top plate for kitchen according to the embodiment of the present invention will be described with reference to FIGS. 1 to 7. In the following description, the "front-back direction" is the direction of the depth of the kitchen, and the "left-right direction" is the direction of the width of the kitchen.

(Frame type kitchen)
FIG. 1 is a perspective view showing a frame-type kitchen 100 according to an embodiment of the present invention. The frame-type kitchen 100 has a structure in which a sink worktop 2 and a stove worktop 3 are arranged on the left and right sides of a central cooking work top plate 1. The sink worktop 2 and the stove worktop 3 are made of stainless steel, and the sink 4 and the stove 5 are arranged respectively, and a shelf plate 6 and a front plate 7 are attached to the frame. The stove worktop includes a worktop for a normal stove that emits a flame using gas, an IH cooking heater, and a worktop for a heating device such as a halogen.

The cooking work top plate 1 is made of wood, and for example, laminated wood made of oak can be used. The mounting structure of the wooden top plate for kitchen according to the present embodiment is for the mounting structure of the top plate 1 for cooking work.

The top plate 1 for cooking work uses urethane coating that is resistant to water so that it can withstand use as a counter worktop in the kitchen, and in addition, the intermediate coating process is increased compared to the normal coating process. As a result, the finish is even more resistant to water than the side plates of conventional urethane-painted system kitchens. Not only the flat surface, but also the end surface and the end surface of the tree are painted.

As a result of conducting a weather resistance test using a xenon weather meter for 1000 hours on the top plate 1 for cooking work (oak laminated wood of about 90 cm square), no cracks in the coating film or infiltration of water were observed. However, when left in a water vapor environment, it stretched in a direction perpendicular to the fiber direction, and the stretch reached 3 to 5 mm. Compared with this, the elongation in the fiber direction was very small and did not reach 1 mm. This elongation is a dimensional change of wood due to a change in moisture content.

For this reason, the problem with water vapor is greater than that of water itself, and furniture in an environment such as ordinary furniture (for example, a dining table) where water spills on the top plate and is wiped off, or the surface is wiped with water. In a kitchen with a stove and a rice cooker and a pot beside it, there is a big difference in the performance and fixing method required for the top plate from the kitchen exposed to the steam environment.

Therefore, the frame-type kitchen 100 whose left and right sides are sandwiched between stainless steel worktops does not have much dimensional allowance to the left and right, so that there are no front-rear restrictions and wall-mounted kitchens with no front-rear restrictions. In this case, it is preferable that the fiber direction of the cooking work top plate 1 is in the left-right direction.

(Frame structure)
FIG. 2 is a perspective view showing the frame structure of the frame type kitchen 100. The frame material is iron, and is composed of a sink frame 20 on the left side, a stove frame 30 on the right side, and a top plate frame 10 connecting them. The vicinity of the center of the stove frame 30 in the front-rear direction is vertically covered with a stainless steel plate 9 in order to take measures against heat and the like, strengthen the rigidity of the frame, and cope with shaking.

The top plate frame 10 is composed of a central frame 11, a front frame 12, and a rear frame 13. The front frame 12 and the rear frame 13 are iron pipe rods having a quadrangular cross section, and the central frame 11 is an iron channel rod having a C-shaped cross section. After the left and right sink frames 20 and the stove frame 30 are assembled, the central frame 11 is temporarily fixed to one of them with screws, and then the front and rear frames 12 and 13 are temporarily fixed with screws. , Temporarily fix them to the other one, fasten them all, and then tighten them to make an integrated kitchen frame.

Since the central frame 11 is a channel having a C-shaped cross section and a long square shape in the front-rear direction, it is possible to reduce the bias of the positions of the left and right sink frames 20 and the stove frame 30 during assembly, and the center. It has the effect of making it difficult for the frame to be assembled in a diamond shape.

Iron does not expand and contract with humidity, and the expansion and contraction (linear expansion coefficient) with temperature is about 0.3 mm to 0.5 mm per 30 degrees (per 1 m length for iron and stainless steel), which is expected to change at room temperature, and the humidity change of wood materials It is smaller than the above and can be absorbed within the clearance range between the wood screw and the hole in the frame.

Each worktop is placed on top of each frame as shown in FIG. That is, the sink worktop 2 including the sink 4 is provided on the sink frame 20, and the stove worktop 3 provided with a groove for installing the stove 5 on the stove frame 30 is the top plate frame 10. A cooking work top plate 1 is placed on the top as a worktop.

Then, each worktop is fixed from below through a hole formed in each frame by a fixing member such as a wood screw or a bolt. In this embodiment, wood screws are used as the fixing member of the top plate. At this time, a gap of 2 to 3 mm is provided between the worktops to facilitate the construction.

The gaps between the worktops and the walls are caulked, that is, sealed, as shown in FIG. As the sealing material 8, for example, a silicone sealing material containing a fungicide can be used. In addition, both sides of the cooking work top plate 1 are finished with a clear color sealing material to ensure the design, and the color sealing material between the wall and the kitchen interior building material is considered as appropriate. It is preferable to use. The properties of the cooking work top plate made of wood-based material have been described earlier. By setting the fiber direction to the left and right, the gaps on both sides of the cooking work top plate 1 and the elasticity of the sealing material make it possible to use the cooking work top plate. It can correspond to the expansion and contraction of the plate 1 in the left-right direction.

As described above, the frame-type kitchen 100 according to the present embodiment has a configuration in which different materials having different dimensional change rates due to moisture and heat, such as a wooden top plate and a metal frame, are combined.

(Correspondence to expansion and contraction in the front-back direction)
Next, with reference to FIGS. 4 to 7, the correspondence to the expansion and contraction of the cooking work top plate 1 in the front-rear direction in the frame-type kitchen 100 will be described. FIG. 4 is a plan view showing the top plate frame 10. As described above, the top plate frame 10 is composed of a central frame 11, a front frame 12, and a rear frame 13. The central frame 11, the front frame 12, and the rear frame 13 are arranged in parallel with the longitudinal direction as the left-right direction.

The central frame 11 is provided with two round holes RH ₁₁ and RH ₁₁ . Further, the front frame 12 and the rear frame ₁₃ are provided with two elongated holes LH ₁₂ , LH ₁₂ , LH ₁₃ and LH ₁₃ , respectively. In each drawing, the reference numeral "RH" indicates a round hole (Round Hole), and "LH" indicates a long hole (Long Hole). The elongated hole LH is formed so as to extend in the front-rear direction of the frame-type kitchen 100. In other words, it is formed so as to extend in the depth direction of each frame.

In other words, the arrangement of the round hole RH and the long hole LH is such that the round hole RH ₁₁ is near the center in the front-rear direction, the long hole LH ₁₂ is near the front in the front-rear direction, and the long hole LH ₁₃ is near the rear in the front-rear direction. , Each is arranged.

FIG. 5 is a cross-sectional view showing a state in which the cooking work top plate 1 is attached, and is viewed in the direction AA of FIG. The cooking work top plate 1 placed on the central frame 11, the front frame 12, and the rear frame 13 was formed on the wood screw S ₁₁ and the front frame 12 passing through the round hole RH ₁₁ formed in the central frame 11. is fixed by wood screws _{S 13} through the long hole _{LH 13} formed in the wood screws _{S 12} and the rear frame 13 through the elongated hole _{LH 12.}

FIG. 6 is an enlarged cross-sectional view of the fixed portion by the wood screws S ₁₁ passing through the round hole RH ₁₁ , and FIG. 7 is an enlarged cross-sectional view of the fixed portion by the wood screws S ₁₂ and S ₁₃ passing through the elongated holes LH ₁₂ and LH _13. It is a figure.

The round hole RH ₁₁ is large enough for the wood screw S _{11 to} pass through. Therefore, by fixing the cooking operation for the top plate 1 with wood screws S _11, it is determined longitudinal position of the cooking operation for the top plate 1. Meanwhile, the long hole _LH 12, _{LH 13} is wood screws _{S 12, S 13} are formed so as to be movable in the longitudinal direction, wood screws _{S 12, S 13} Where the long hole _LH 12, _{LH 13} It is fixed at that position.

The distance between the center of the round hole RH ₁₁ of the central frame 11 and the center of the elongated hole LH ₁₂ of the front frame 12 on the lower surface of the cooking work top plate 1 between when it is stretched and when it is shrunk due to a change in humidity. , and to come to a position corresponding to the distance between the long hole LH ₁₃ center of the round hole RH ₁₁ center and the rear frame 13 of the center frame 11, it is preferable to provide a fixing hole of the preliminarily wood screws S.

When the top plate 1 for cooking work expands and contracts in the front-rear direction due to a change in humidity, as shown in FIGS. 5 to 7, the position of the wood screw S ₁₁ passing through the round hole RH ₁₁ does not change, but the long hole LH ₁₂ , The wood screws S ₁₂ and S ₁₃ passing through the LH ₁₃ slide and move in the elongated hole. As a result, even if the top plate 1 for cooking work expands and contracts in the front-rear direction, it is possible to prevent warping and cracking of the wood top plate, distortion of the frame, and the like.

Here, for comparison, the mounting structure of the wooden top plate for kitchen according to the conventional example will be described. FIG. 8 is a plan view showing a top plate frame according to a conventional example, and FIG. 9 is a cross-sectional view showing a state in which the cooking work top plate 1 according to the conventional example is attached, and FIG. It is a view in the direction. The top plate frame according to the conventional example is composed of a front frame 92 and a rear frame 93, and round holes RH ₉₂ and RH ₉₃ are formed in each of them. When the top plate 1 for cooking work is fixed to this frame by wood screws S ₉₂ and S ₉₃ and placed in a humidity atmosphere, the top plate extends in the front-rear direction. At this time, since the parts fixed by the wood screws S ₉₂ and S ₉₃ do not move, a force is applied to the top plate. Since the amount of elongation is as large as 3 to 5 mm, as a result, warpage occurs as shown in FIG. 9, and when used as a cooking workbench, the placed object becomes unstable.

On the other hand, according to the mounting structure of the wooden top plate for kitchen according to the present embodiment, the large force applied by the elongation of the top plate is absorbed by the movement of the wood screws S ₁₂ and S _{13 in} the elongated holes. It is possible to prevent the top plate from warping.

In the case of a wall-mounted kitchen, if the top plate extends backward, it will approach the wall, but as mentioned above, the margin due to the gap at the time of installation and the elasticity of the sealing material will not hinder the elongation of the top plate. Can be constructed in.

Further, in the present embodiment, the position of the central frame is slightly shifted rearward. By arranging in this way, it is possible to reduce the amount of extension of the top plate to the rear, and it is effective to obtain a sufficient margin even with a small gap in the rear where the degree of freedom is less than that in the front.

Further, it is preferable that the frame having the elongated holes LH is subjected to uneven processing so that the wood screws S can easily slide when the top plate is expanded and contracted to make it slippery. For example, it is possible to apply a coating having irregularities on the surface.

In addition, by making the end face on the extending side of the top plate chamfered such as a curved surface at the corner in the thickness direction and the corner in the left-right direction, the top plate for cooking work extending forward can be placed on the left and right sides. The design can be designed to eliminate the discomfort that appears in front of the adjacent worktop, and it will not get caught during work.

Further, since both the center and the front and rear are fixed along the frame surface, even if the top plate is distorted or warped from the beginning, it is fixed while being corrected. That is, if it is warped upward, it is corrected along the frame surface by the wood screw of the center frame, and if it is warped upward, it is corrected so that it is along the frame surface by the wood screw of the front and rear frames. Will be done. At this time, if the number of round holes RH or long holes LH formed in each frame is increased, the correction effect can be further provided. Further, by providing the elongated hole LH at a position as far as possible from the central round hole RH and fixing it, the warp can be effectively suppressed.

In the mounting structure of the kitchen wood top plate according to the present embodiment, the kitchen wood top plate 1 is fixed on the three frames 11, 12, and 13. The wooden top plate 1 has a fixing member S ₁₁ passing through a round hole RH ₁₁ formed in the frame 11 of the three frames and a long hole in the front-rear direction formed in the frames 12 and 13 of the three frames. It is fixed by the fixing members S ₁₂ and S ₁₃ passing through the LH ₁₂ and LH ₁₃ . Then, as the wood top plate 1 expands and contracts in the front-rear direction, the fixing members S ₁₂ and S ₁₃ passing through the elongated holes LH ₁₂ and LH ₁₃ move. Therefore, when the wooden top plate 1 expands and contracts according to the water content, the fixing member S ₁₁ passing through the round hole RH ₁₁ does not move, and the fixing members S ₁₂ and S ₁₃ passing through the long holes LH ₁₂ and LH ₁₃ do not move. By moving, it is possible to treat the stress generated with the kitchen body and prevent the wooden top plate 1 from warping or cracking, distortion of the frame, or the like.

Further, since the three frames 11, 12, and 13 are arranged with the longitudinal direction as the left-right direction, it is possible to form a structure in which either a round hole RH or a long hole LH is formed for each frame.

Further, since the round hole RH ₁₁ is arranged near the center in the front-rear direction, the fixing members S ₁₁ near the center do not move and the fixing members S ₁₂ and S ₁₃ other than near the center move. By allowing both elongations to, the length of elongation (stress) can be dispersed.

Further, since the fiber direction of the wood top plate 1 is set to the left-right direction, the directions of the elongated holes LH ₁₂ and LH ₁₃ can be aligned with the direction in which the wood top plate is easily expanded and contracted.

Further, since the sink worktop 2, the stove worktop 3 or the wall is arranged adjacent to the wooden top plate 1, the sink worktop 2, the stove worktop 3 or the wooden top plate 1 avoids the direction in which the wooden top plate 1 easily expands and contracts. Walls can be placed.

Further, since a gap is provided between the wood top plate 1 and the adjacent sink work top 2, the stove work top 3, or the wall, and the sealing material 8 is inserted in the gap, the wood top plate 1 is oriented in the left-right direction. The slight expansion and contraction that occurs in the above can be dealt with by the gap and the elasticity of the sealing material 8.

Further, when the frame is unevenly processed, the frame can be made slippery so that the fixing member S passing through the elongated hole LH can easily move.

Further, when the fixing hole S of the fixing member S is provided in advance on the back surface of the wooden top plate 1, it is easy to fix by the fixing member S.

As described above, according to the mounting structure of the wooden top plate for kitchen according to the present embodiment, when the wooden top plate is used for the system kitchen, the kitchen main body and the kitchen main body are caused by the expansion and contraction of the wooden top plate according to the water content. By treating the stress generated between the wooden top plates, it is possible to prevent warping and cracking of the wooden top plate, distortion of the frame, and the like.

Although the mounting structure of the wooden top plate for kitchen according to the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various other modifications are possible.

For example, in the above embodiment, the number of frames is three, but if a round hole is formed in one frame and an elongated hole is formed in the remaining frame, the number of frames may be two or four or more. It is possible. It is also possible to form round holes in the two frames. However, in that case, it is preferable to arrange the two frames close to each other to shorten the distance that cannot correspond to the expansion and contraction of the wooden top plate. In consideration of the balance between cost and stability, it is preferable to set the number of frames to three.

Further, in the above embodiment, the number of round holes RH or elongated holes LH formed in each frame is set to two, but the number is not particularly limited.

Further, in the above embodiment, the left side is a sink worktop and the right side is a stove worktop, but the left and right sides may be reversed, and one side may be another kitchen element (such as another worktop, a system kitchen). It may be arranged as a combination) or a wall.

Further, in the above embodiment, the top plate is made of laminated oak, but any wood-based material having anisotropy in dimensional change due to the water content causes the same problem, and these can be solved by the above structure. .. Corresponding anisotropy wood-based materials include solid boards, weft strips, laminated wood, vertical slabs, LVL (single board laminates), or laminates that are laminated by changing the fiber direction of a small number of layers. and so on. As these materials, hardwoods such as oak are preferably used. Hardwood has a high specific gravity and excellent durability, but on the other hand, it has a strong expansion and contraction force due to water and humidity, and it is necessary to treat stress and use it as a wooden top plate.

Further, in the above embodiment, wood screws are used as the fixing member, but bolts and nuts or the like can also be used.

Further, in the above embodiment, the wooden top plate for kitchen is used as the top plate for cooking work, but the top plate of kitchen furniture used in the kitchen can also be applied.

Further, like the frame for the top plate according to the other embodiment shown in FIG. 10, the central frame 41 can be provided in the center in the front-rear direction to make the intervals even (D ₁ = D ₂ ). By doing so, it is possible to cope with the expansion and contraction of the wooden top plate 1 in the front-rear direction in a well-balanced manner.

Further, as in the frame for the top plate according to another embodiment shown in FIG. 11, the rear frame ₅₃ may be provided with the round hole RH ₅₃ , and the central frame 51 and the front frame 52 may be provided with the elongated holes LH ₅₁ and LH _52. it can. In other words, the round hole RH ₅₃ is arranged near the rear in the front-rear direction, the elongated hole LH ₅₁ is arranged near the center in the front-rear direction, and the elongated hole LH ₅₂ is arranged near the front in the front-rear direction. In this way, the fixing member in the vicinity of the rear does not move and the fixing member other than the vicinity of the rear moves. Therefore, by allowing only the extension from the vicinity of the rear to the front, the elongation allowance can be increased when the rear is a wall or the like. Can be secured. Further, the elongated hole LH ₅₂ is preferably longer than the central elongated hole LH ₅₁ . In addition, by making the end face on the extending side of the top plate chamfered such as a curved surface at the corner in the thickness direction and the corner in the left-right direction, the top plate for cooking work extending forward can be placed on the left and right sides. The design can be designed to eliminate the discomfort that appears in front of the adjacent worktop, and it will not get caught during work.

Further, like the top plate frame according to another embodiment shown in FIG. 12, the two vertical frames 61, 61 are parallel to each other with the longitudinal direction as the front-rear direction so as to connect the front frame 62 and the rear frame 63. Each vertical frame 61 may be provided with a round hole RH ₆₁ and an elongated hole LH ₆₁ . In this way, it is possible to form a structure in which both the round hole RH and the long hole LH are formed in each frame. By doing so, since the round hole RH ₆₁ and the long hole LH ₆₁ are present in one material (frame 61), the deformation elements of the frame 61 are reduced, and the distortion of the frame can be further suppressed.

Further, as in the frame for the top plate according to another embodiment shown in FIG. 13, one vertical frame 71 is arranged with the longitudinal direction as the front-rear direction so as to connect the front frame 72 and the rear frame 73, and vertically. Round holes RH ₇₁ may be provided in the frame 71, and elongated holes LH ₇₂ and LH ₇₃ may be provided in the front and rear frames 72 and ₇₃ .

As described above, in the mounting structure of the wooden top plate for kitchen of the present invention, the arrangement of the plurality of frames for fixing the top plate is not particularly limited, and at least one of the plurality of frames is formed with a round hole RH. It is sufficient that a long hole LH is formed in at least one of the frames.

Further, the plurality of frames can be appropriately configured by combining a frame having the longitudinal direction in the left-right direction and a frame having the longitudinal direction in the front-rear direction. Further, it is also possible to form a round hole RH or a long hole LH in the diagonal frame by combining the frames whose longitudinal direction is oblique.

Further, when a plurality of round holes RH are formed, the positions of the round holes RH in the front-rear direction do not necessarily have to be the same, but if the positions of the fixing members that do not move are too far in the front-rear direction, the wooden top plate Since it is possible that the treatment of stress generated between the kitchen body and the kitchen body during expansion and contraction will be non-uniform, it is preferable to match as much as possible. Further, it is more preferable that any of the holes is near the center of the top plate.

Further, it can be applied to the mounting structure of the shelf board shown in FIG. The frame-type kitchen shelf board 80 shown in FIG. 14 is attached to the vertical frames 81 and 81 via the fixing bracket 82. A round hole RH is formed in the center of the fixing bracket 82, and elongated holes LH are formed at both ends, and the shelf board 80 is fixed by a wood screw S via the fixing bracket 82.
