[0011] The tabletop structure 1 is formed by a tabletop 2 and an arrangement of members around the tabletop 2 for stably holding the tabletop 2. As shown in Fig. 2, the tabletop structure 1 has a tabletop 2, a frame 3, a groove 4, a gap 5, and a backing material 6. In this specification, the outside means the outer edge side of the tabletop 2 and the side away from the outer edge of the tabletop 2. The inside means the center side of the tabletop 2.

[0012] As shown in FIG. 1, the top plate 2 is generally rectangular in plan view and has a thin, generally rectangular parallelepiped plate shape. The top plate 2 has an upper surface 21, a lower surface 22, a top plate end surface 23, a long edge 24, and a short edge 25. The top surface 21 is located on the upper side when placed in the kitchen unit 10, and is a surface that extends in a generally horizontal direction. The lower surface 22 is a surface that faces the top surface 21 and extends downward. The long edges 24 are outer edges that are arranged in a pair along the longitudinal direction of the top plate 2. The short edges 25 are outer edges that are arranged in a pair along the lateral direction of the top plate 2. The top plate 2 is made of, for example, ceramic.

[0013] The top plate end surface 23 is a surface that connects the upper surface 21 and the lower surface 22 and extends in the up-down direction. The top plate end surface 23 has a chamfered portion 230. The chamfered portion 230 is disposed at the upper end of the top plate end surface 23, and is formed by cutting the corners of the plate-shaped top plate so that they are inclined. The chamfered portion 230 is inclined downward and outward from the upper surface 21 of the top plate 2 toward the top plate end surface 23.

[0014] The frame 3 is a long member that is arranged below the end portion 2a of the tabletop 2 and along the long edge 24 of the tabletop 2. The frame 3 has a support portion 30, a rising portion 35, a water return groove 36, and a printed portion 37. The frame 3 is made of aluminum.

[0015] The support portion 30 is configured by a hollow structure having a generally rectangular cross section, and supports the underside of the end portion 2a of the top plate 2. The support portion 30 has a support portion upper surface portion 31, a support portion lower surface portion 32 as the lower surface of the support portion 30, an outer end surface 33 as the support portion end surface, and an inner end surface 34. The support portion upper surface portion 31 is a surface that constitutes the upper surface of the hollow structure and contacts the lower surface 22 of the top plate 2. The support portion lower surface portion 32 is a surface that constitutes the lower surface of the hollow structure and is disposed opposite the support portion upper surface portion 31. The outer end surface 33 is a surface that is located on the outer edge side of the top plate 2 among the end surfaces extending in the vertical direction of the support portion 30. The inner end surface 34 is a surface that extends in the vertical direction opposite the outer end surface 33. The inner end surface 34 is located closer to the center in the width direction of the short edge 25 of the top plate 2 than the outer end surface 33, and contacts the backing material 6 described later. The outer end surface 33 and the inner end surface 34 both connect the support upper surface portion 31 and the support lower surface portion 32 .

[0016] The rising portion 35 extends upward from the upper end of the outer end surface 33 of the support portion 30, and rises so as to cover the top plate end surface 23. The upper end of the rising portion 35 extends to the upper part of the top plate end surface 23. A part of the upper end side of the rising portion 35 contacts the lower end of the chamfered portion 230. The rising portion 35 has a cover portion 351 and an inclined portion 352.

[0017] The cover portion 351 is a flat surface extending along the top plate end surface 23 and approximately parallel to the top plate end surface 23. A gap 5, which will be described later, is formed between the cover portion 351 and the top plate end surface 23. The cover portion 351 is continuous with the outer end surface 33 of the support portion 30 and extends upward while being flush with the outer end surface 33.

[0018] The inclined portion 352 is a portion inclined from the upper end side of the cover portion 351 toward the top plate end surface 23. The inclined portion 352 has a triangular cross-sectional portion 3521 and a tip portion 3522. The triangular cross-sectional portion 3521 is a generally triangular portion in cross section formed between an imaginary line 3521a extending in a substantially horizontal direction at the upper end of the cover portion 351, a linear surface 3521b inclined from the outer surface of the cover portion 351 toward the top plate end surface 23, and an imaginary line 3521c extending from the inner surface of the cover portion 351 to the upper end of the surface 3521b. The tip portion 3522 has an upper portion that abuts against the lower end of the chamfered portion 230 of the top plate 2. The tip portion 3522 is a portion that protrudes inward from a portion of the triangular cross-sectional portion 3521 facing the top plate end surface 23 until it abuts against the top plate end surface 23. The tip portion 3522 has, on the upper side, an upper curved surface 3522a that slopes downward from the upper end of the triangular cross-section portion 3521. The tip portion 3522 has, on the lower side, a lower curved surface 3522b that slopes upward from the inner end portion of the cover portion 351.

[0019] The water return groove 36 is formed on the lower end side of the outer end face 33 of the support part underside 32, and extends along the long arm direction of the frame 3. The water return groove 36 is a recess formed by recessing upward from the lower end of the outer end face 33 and the support part underside 32, and is formed in a generally U-shape in cross section with an open lower portion.

[0020] The printed portion 37 is a printed surface applied to the rising portion 35 and the outer surface of the outer end face 33. The printed portion 37 is colored by anodizing.

[0021] The groove 4 is formed between the chamfered portion 230 of the tabletop 2 and the tip 3522 of the inclined portion 352 in the rising portion 35. The groove 4 is a small recess that is approximately V-shaped in cross section. The groove 4 is formed when the chamfered portion 230, which slopes downward toward the outside of the tabletop 2, comes into contact with the upper curved surface 3522a of the tip 3522 at a position slightly lower than the upper surface 21 of the tabletop 2. The groove 4 is filled with a colored adhesive 41 that has been adjusted to match the color of the tabletop 2 and the color of the frame 3.

[0022] The gap 5 is formed between the frame 3 and the top plate 2, and has a generally L-shaped cross section. The long side of the gap 5 is formed between the inner surface of the cover portion 351 at the rising portion 35 and the top plate end surface 23 at the end 2a of the top plate 2. The short side of the gap 5 is formed between the part of the support portion upper surface portion 31 on the rising portion 35 side and the lower surface 22 at the end 2a of the top plate. The gap 5 is filled with an adhesive 51 that bonds the top plate 2 and the frame 3 together.

[0023] The backing material 6 is a plate that is disposed on the underside of the top plate 2 and reinforces the top plate 2. The backing material 6 has a backing material upper surface portion 61, a backing material lower surface portion 62, and a backing material end surface 63. The backing material upper surface portion 61 is adhered to the underside 22 of the top plate 2. The backing material lower surface portion 62 is the surface opposite to the backing material upper surface portion 61, and is supported by the cabinet 12. The backing material end surface 63 is adhered to the inner end surface 34 of the support portion 30. The backing material 6 is made of, for example, wood, medium density fiberboard (MDF), etc.

[0024] According to this embodiment, the following effects are achieved. The top plate structure 1 is configured to include a plate-shaped top plate 2 and a frame 3 arranged under the end 2a of the top plate 2 along the direction in which the long edge 24 of the top plate 2 extends. The frame 3 is configured to include a support part 30 that supports the underside of the end 2a of the top plate 2, and a rising part 35 that extends from the outer end surface 33 extending in the vertical direction of the support part 30 and rises up to cover the top plate end surface 23 of the end 2a of the top plate 2, and the upper end of the rising part 35 is formed to extend to the upper part of the top plate end surface 23. Since the rising part 35 extends to the upper part of the top plate end surface 23 at the end 2a of the top plate 2, the top plate 2 can be easily protected. Although the rising part 35 extends to the upper part, it does not cover the upper surface 21 of the top plate 2, so that when viewed from above the kitchen unit 10, the rising part 35 is not noticeable in a plan view, and a good appearance is obtained.

[0025] According to this embodiment, the upper end of the tabletop end surface 23 is configured to include an inclined chamfered portion 230, and the upper end side of the rising portion 35 is configured to be in contact with the lower end of the chamfered portion 230. When the rising portion 35 is configured to extend to the upper end of the tabletop end surface 23, it may be difficult to make the upper end of the rising portion 35 reach the exact same height as the upper end of the tabletop end surface 23 from the viewpoint of the convenience of the manufacturing process and the nature of the material. By arranging the rising portion 35 to be in contact with the lower end of the chamfered portion 230, it is possible to extend the rising portion 35 to the very near vicinity of the upper end of the tabletop end surface 23, and since the tabletop end surface 23 has the chamfered portion 230, it is possible to avoid inconveniences such as chipping of the corners of the tabletop 2 or the installer or user hitting the corners.

[0026] According to this embodiment, the rising portion 35 includes a cover portion 351 extending along the top plate end surface 23, and an inclined portion 352 inclined from the upper end side of the cover portion 351 toward the top plate end surface 23, the upper portion of which abuts against the lower side of the chamfered portion 230 on the top plate end surface 23. A groove portion 4 is formed between the chamfered portion 230 and the tip of the inclined portion 352. When the rising portion 35 is extended to the upper portion of the top plate end surface 23, the groove portion 4 is formed between the chamfered portion 230 and the inclined portion 352. For example, a colored adhesive 41 is filled in this groove portion, so that the appearance of the end portion 2a of the top plate 2 viewed from above can be improved.

[0027] According to this embodiment, the support portion 30 is configured with a hollow structure having an approximately rectangular cross section and includes a support portion upper surface portion 31 that contacts the underside 22 of the tabletop 2, and a gap 5 that is approximately L-shaped in cross section is arranged between the rising portion 35 and the portion of the support portion upper surface portion 31 on the rising portion 35 side and the tabletop end surface 23 and the underside 22 of the end portion 2a of the tabletop 2. By forming a substantially L-shaped gap 5 between the top plate end face 23 and the rising portion 35, and between the part of the support part upper surface portion 31 on the rising portion 35 side and the underside 22 of the top plate 2, when adhesive is applied to the top plate 2 and attached to the frame 3, the excess adhesive fills the gap 5, so that the top plate 2 and the frame 3 can be accurately attached. The top plate end face 23 does not necessarily have a completely flat surface, and depending on the material, the surface may be uneven. However, by forming the gap 5 between the rising portion 35 and the end 2a of the top plate 2, it becomes possible to absorb the variation in shape depending on the material of the top plate 2.

[0028] According to this embodiment, the support part 30 is configured to include a water return groove 36 formed on the lower end side of the outer end face 33 of the support part underside 32, recessed upward. Even if water used on the kitchen counter 11 falls from the upper surface of the top board 2, along the rising part 35 of the frame 3 and the outer end face 33 of the support part 30, the water return groove 36 can prevent the water from flowing around from the lower end of the outer end face 33 towards the support part underside 32.

[0029] The present disclosure is not limited to the above embodiment, and modifications, improvements, etc. within the scope of achieving the object of the present disclosure are included in the present disclosure. As shown in FIG. 3A and FIG. 3B, the thickness of the tabletop 2 and the height of the support parts 30A and 30B can be changed as appropriate. The tabletop 2A shown in FIG. 3A is thicker than the tabletop 2 shown in FIG. 2 described in the above embodiment, and the height of the support part 30A is lower than the support part 30 shown in FIG. 2. The tabletop 2B shown in FIG. 3B is thicker than the tabletop 2A shown in FIG. 3A, and the height of the support part 30B shown in FIG. 3B is lower than the support part 30A shown in FIG. 3A. The thickness and height of the tabletop and the support part are not limited. In FIG. 3A and FIG. 3B, the thickness of the tabletop structure is the same. In this case, by changing the height of the support part according to the thickness of the tabletop, the end surface of the tabletop can be protected without changing the thickness of the tabletop structure. On the other hand, the thickness of the entire tabletop structure may also be changed as appropriate. [Explanation of symbols]
