Description

[[Technical Field]]

[0001] The present invention relates to a frame and a table. [[Background Art]]

[0002] Tables such as kitchen counters, washstands and tables comprise a frame provided with legs and crosspieces, and a top plate fixed onto the frame. The table may also include a shelf. As the top plate, in addition to resin top plates that can be designed into free shapes, there are also stone top plates such as marble and artificial stone, tiled top plates, metal top plates and the like.

[0003] Conventionally, in the manufacturing of such tables, it is common practice to prepare a top plate formed by bonding a structural material such as plywood to the back surface of a surface material, and fix the structural material on the frame and the frame with metal fittings such as screws. In addition, Patent Document 1 proposes a technique of fixing a top plate to a frame with an adhesive without using such metal fittings. [[Prior Art Documents]] [[Patent Documents]]

[0004] [[Patent Document 1]] Japanese Unexamined Patent Publication No. 2000-139738 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0005] Fig. 10 is a schematic diagram of a table according to the prior art. As shown in Fig. 10, in this table 100, the top plate 110 comprises a surface material 111 located on the upper surface side and a structural material 112 located on the lower surface side. The structural material 112 is fixed by screws 130 while being placed on the frame 120. Further, the structural material 112 is provided with an edge member 113 on its side surface so that the side surface cannot be seen from the outside. However, in such a table 100, the top plate 110 has a total thickness of the surface material 111 and the structural material 112, which reduces the degree of freedom in the shape of the top plate, for example, the top plate 110 cannot be made thin.

[0006] If the method described in Patent Document 1 assumes that the top plate is bonded to the frame, there is a problem in that the transport size becomes large.

[0007] One of the objectives of the present invention is to provide a frame and a base that offer a high degree of freedom in the shape of the top plate. [Means for solving the problem]

[0008] The present invention is characterized by the frame described in (1) below and the base described in (2) below.

[0009] (1) A frame for a stand having a top plate, wherein the frame comprises legs, crossbars, and a support fitting for connecting the top plate and the frame, and the support fitting is attached to the inside of the crossbars such that its upper surface is positioned at a first position lower than the upper surface of the crossbars.

[0010] (2) A stand having a top plate and the frame described above. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a frame and a base that offer a high degree of freedom in the shape of the top plate. [Brief explanation of the drawing]

DESCRIPTION OF EMBODIMENTS

[0013] Hereinafter, the table and the frame body according to embodiments will be described with reference to the drawings. Fig. 1 is a perspective view showing an example of the table. Fig. 2 is a perspective view showing an example of the frame body. Fig. 3 is a partial cross-sectional view showing an example of the frame body.

[0014] Regarding the table As shown in Fig. 1, the table 10 includes a top plate 11 and a frame body 12. The table 10 is not limited to the table shown in Fig. 1, and examples thereof include kitchen counters, washstands, tables, and the like. The table 10 may include a shelf (not shown).

[0015] Examples of the top plate 11 include screwable resin top plates and wooden top plates, as well as stone top plates such as marble and artificial stone, tiled top plates, and metal top plates. When the top plate 11 is made of a material that is difficult to screw like a stone top plate, a top plate having a surface material 11a located on the upper surface side and a structural material 11b located on the lower surface side is used. In this case, as shown in Fig. 3, the outer edge of the structural material 11b is arranged inside the inner edge of the crosspiece 12a of the frame body 12, and the top plate 11 is attached to the receiving bracket 12c with a screw 13b or the like in a state where the lower surface of the surface material 11a is in contact with the upper surface of the crosspiece 12a and the lower surface of the structural material 11b is in contact with the upper surface of the receiving bracket 12c.

[0016] Thus, the top plate 11 can be reliably fixed to the frame body 12, and since the structural member 11b is accommodated inside the crosspiece portion 12a, it is not visible from the outside, and only the surface material 11a is visible from the outside, thereby increasing the degree of freedom in the shape of the top plate 11. For example, even when a thin top plate such as marble with a thickness of 10 mm is used as the surface material 11a, the structural member 11b can be accommodated inside the remaining portion 11a, so a table with a sophisticated high-grade feel and a sharp impression can be provided.

[0017] For example, the top plate 11 may be configured such that the outer edge of the surface material 11a is arranged outside the outer edge of the crosspiece portion 12a. Further, when thin wood is used for the top plate 11, similar to the above, a material having a surface material 11a made of wood and a structural member 11b located on the lower surface side may be used, or the top plate 11 made of thick wood may be prepared, and the edge portion may be cut out to provide a recess, thereby processing the top plate into a shape including a thin surface material 11a and a structural member 11b.

[0018] (Regarding the Frame Body) As shown in Figure 2, the frame body 12 includes a crosspiece portion 12a, leg portions 12b, and a receiving bracket 12c. As shown in Figure 3, the receiving bracket 12c is an L-shaped member, and is provided with through holes into which a screw (bolt) 13a and a screw 12c can be inserted respectively on two surfaces thereof; the receiving bracket 12c is connected to the crosspiece portion 12a via the bolt 13a, and connected to the top plate 11 (structural member 11b) via the screw 12c. The receiving bracket 12c is attached to the inside of the crosspiece portion 12a such that the upper surface thereof is arranged at a first position lower than the upper surface of the crosspiece portion 12a. Accordingly, even when the top plate 11 including the surface material 11a and the structural member 11b is used, the top plate 11 and the frame body 12 can be connected such that the structural member 11b is not visible from the outside.

[0019] As shown in the example in Figure 3, if the vertical length between the upper surface of the crossbar 12a and the upper surface of the mounting bracket 12c is made to match the thickness of the structural material 11b, the lower surface of the surface material 11a can be made to contact the upper surface of the crossbar 12a. However, if there is concern that the surface material 11a may be damaged by direct contact between the surface material 11a and the crossbar 12a, a gap can be created between the surface material 11a and the crossbar 12a by making the vertical length between the upper surface of the crossbar 12a and the upper surface of the mounting bracket 12c shorter than the thickness of the structural material 11b. In this case, it is also possible to insert a cushioning material between the surface material 11a and the crossbar 12a. In these cases as well, the vertical length between the upper surface of the crossbar 12a and the upper surface of the mounting bracket 12c can be said to be matched to the thickness of the structural material 11b. The same applies in the following explanation.

[0020] As shown in the example in Figure 3, a square pipe can be used as the crossbar 12a. This is because the square pipe is lightweight while possessing sufficient strength. Alternatively, an L-shaped angle can be used as the crossbar 12a. In this case, one of the two sides of the L-shaped angle will also serve as the support bracket 12c. However, it is preferable to use a square pipe due to the balance between strength and mass. Furthermore, the crossbar 12a is preferably connected to the leg portion 12b by welding or the like to form the frame 12.

[0021] As shown in Figure 2, it is preferable that the crossbars 12a are connectable. That is, the crossbars 12a can be made by connecting the end crossbars 18 and the middle crossbars 19 in the longitudinal crossbars that constitute the longitudinal direction of the frame 12. Both ends of the middle crossbars 19 are provided with connecting parts that have an outer surface shape that is slidable against the inner surface of the end crossbars 18. Threaded holes are cut into the connecting parts of the middle crossbars 19, and holes are provided on the inner edge of the end crossbars 18 at positions corresponding to these threaded holes. The end crossbars 18 and the middle crossbars 19 can be connected by fixing them with screws (bolts) 30 or the like, so that these holes and the threaded holes align. With such a configuration, it becomes easy to assemble frame 12 of various sizes by changing the length of the middle crossbars 19. In addition, the packaging size during transport can be reduced, and transportation costs can be lowered.

[0022] In the example shown in Figure 2, two members, each consisting of one horizontal bar 17, two end bars 18, and two leg sections 12b welded together, are connected to two intermediate bars 19. In the example shown in the figure, a horizontal bar 17 of approximately 700 mm is assumed, so the horizontal bar 17 is constructed as a single unit, but like the vertical bars, it may also be constructed by connecting them.

[0023] In the example shown in Figure 2, the leg portion 12b is exemplified as being welded to the outside of the corner of the crossbar portion 12a, but the leg portion 12b can be of various shapes to match the design of the base 10. From the viewpoint of facilitating assembly work and transportation, it is preferable that it be welded to all or part of the crossbar portion 12a in advance.

[0024] In the example shown in Figure 3, the receiving bracket 12c is an L-shaped member with through holes in each of its two planes and is connected to the crossbar 12a by bolts 13a. However, the bolts 13a may be connected to the crossbar 12a by welding or other methods.

[0025] In the example shown in Figure 3, the top plate 11 is attached to the support bracket 12c with screws 13b or the like. However, since the structure 11b is housed in a space enclosed by the inner edge of the crossbar 12a and its horizontal movement is restricted, it is not necessary to fix the top plate 11 to the support bracket 12c with screws 13b or the like.

[0026] (Regarding other frame types) The following sections will explain examples of other frame structures using Figures 4-8. Figure 4 is a partial cross-sectional view showing an example of a mounting bracket. Figure 5 is a partial cross-sectional view showing an example of how to use the mounting bracket (an example when using thick structural material). Figure 6 is a partial cross-sectional view showing an example of how to use the mounting bracket (an example when using thin structural material). Figure 7 is a partial cross-sectional view showing an example of how to use the mounting bracket (an example when the top plate can be fastened with screws). Figure 8 is a partial cross-sectional view showing an example of how to use the mounting bracket (an example when the top plate cannot be fastened with screws).

[0027] As shown in Figure 4, a support bracket 12d is used in this example. The support bracket 12d is an L-shaped member having two facing members 12e and 12f, with one through-hole 14a in one facing member 12e and two through-holes 14b and 14c in the other facing member 12f. When the distance from the corner of the through-hole 14a is L1, the distance from the corner of the through-hole 14b is L2, and the distance from the corner of the through-hole 14c is L3, the distances L1, L2, and L3 are all different. Furthermore, distance L1 coincides with the relative vertical distance from the through-hole 15 of the crossbar 12a to the upper surface of the crossbar 12a. The frame 12 using this support bracket 12d will be described below.

[0028] First, in the example shown in Figure 5, the top plate 11 is composed of a surface material 11a and a relatively thick structural material 11b (for example, 18mm structural plywood). The horizontal rail 12a and the support bracket 12d are connected at a position where the through hole 15 and the through hole 14b coincide. At this time, the vertical length between the upper surface of the rail 12a and the upper surface of the support bracket 12c is equal to the thickness of the structural material 11b, so the top plate 11 is attached to the support bracket 12d and connected to the frame 12 with the lower surface of the surface material 11a in contact with the upper surface of the rail 12a and the lower surface of the structural material 11b in contact with the upper surface of the support bracket 12d.

[0029] Next, in the example shown in Figure 6, the top plate 11 is composed of a surface material 11a and a relatively thin structural material 11c (for example, 12mm structural plywood). The horizontal rail 12a and the support bracket 12d are connected at a position where the through holes 15 and 14c coincide. In this case, the vertical length between the upper surface of the rail 12a and the upper surface of the support bracket 12c is equal to the thickness of the structural material 11c. Thus, this support bracket 12d can also be used when the thickness of the structural material 11c is thin.

[0030] Next, in the example shown in Figure 7, the top plate 11 is made of a top plate that can be fastened with screws. The horizontal bar 12a and the support bracket 12d are connected at a position where the through hole 15 and the through hole 14a coincide. At this time, the upper surface of the bar 12a and the upper surface of the support bracket 12c coincide. Thus, this support bracket 12d can also be used in the case of a surface material 11a that can be fastened with screws.

[0031] Next, in the example shown in Figure 8, the top plate 11 is made of a material that cannot be fastened with screws. An elastic material 16, such as resin, is attached to the upper surface of the horizontal bar 12a as a cushioning material, and the top plate 11 is placed on top of this elastic material 16. In this way, if the mounting bracket is configured to be detachable from the horizontal bar 12a, a top plate that cannot be fastened with screws can be placed on it.

[0032] Thus, a frame 12 using a mounting bracket 12d whose upper surface position can be changed in various ways can accommodate various tabletop shapes. As a result, parts can be standardized, which contributes to reducing inventory burden and also to reducing manufacturing costs.

[0033] As shown in Figure 4, the mounting bracket 12d is provided with two through holes 14b and 14c in the facing material 12f at different distances from the corners, but the through holes may be elongated holes extending away from the corners. In the above example, the mounting bracket has an L-shaped cross-section, but it may also have a U-shaped or square-shaped cross-section. Furthermore, the mounting bracket may be a short member or a long member (so-called angle).

[0034] Figure 9 is a perspective view showing an example of a frame using U-shaped support brackets. As shown in Figure 9, the frame 12 comprises a crossbar 12a, a leg portion 12b, and support brackets 12c and 12h. As shown in Figure 3, the support bracket 12c is an L-shaped member with through holes on each of its two faces into which bolts and screws can be inserted, and the support bracket 12h is a U-shaped member (angle) with through holes on each of its three faces into which bolts and screws can be inserted. Both the support brackets 12c and 12h are connected to the crossbar 12a by bolts and connected to the top plate by screws. The support brackets 12c and 12h are attached to the inside of the crossbar 12a such that their upper surfaces are positioned at a first position below the upper surface of the crossbar 12a. This makes it possible to connect the top plate 11 and the frame 12 in a way that prevents the structural material 11b from being visible from the outside, even when using a top plate 11 that includes a surface material 11a and a structural material 11b. The 12h mounting bracket is useful in situations where particularly high strength is required, such as with long tabletops. [Industrial applicability]
