Abstract
Description
Technical Field
[0001] The present invention relates to a frame and a base.
Background Art
[0002] Bases such as kitchen sinks, washbasins, and tables include a frame having legs and crossbars, and a top plate fixed on the frame. The base may include a shelf. As the top plate, in addition to a resin top plate that can be designed in a free shape, there are stone top plates such as marble and artificial stone, tiled top plates, metal top plates, and the like.
[0003] Conventionally, for manufacturing such a base, a top plate with a structural material such as plywood attached to the back surface of the surface material is prepared, and a technique of fixing the structural material on the frame and the frame with a metal fitting such as a screw is common. Further, Patent Document 1 proposes a technique of fixing the top plate to the frame with an adhesive without using such a metal fitting.

Summary of the Invention
Problems to be Solved by the Invention
[0005] FIG. 10 shows a schematic view of a base according to the prior art. As shown in FIG. 10, in this base 100, the top plate 110 includes 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 a screw (bolt) 130 in a state of being placed on the frame 120. And the structural material 112 is provided with an edge member 113 on the side surface so that the side surface is not visible from the outside. However, in such a base 100, the top plate 110 has a total thickness of the surface material 111 and the structural material 112, and for example, the degree of freedom of the top plate shape is reduced such that the top plate 110 cannot be made thinner.
[0006] If adhesion to the top plate frame is assumed as in the method of Patent Document 1, there is a problem that the conveyance size increases.
[0007] One object of the present invention is to provide a frame and a base with a high degree of freedom in the shape of the top plate.
Means for Solving the Problems
[0008] The present invention mainly comprises the frame of the following (1) and the base of the following (2).
[0009] (1) A frame of a base having a top plate, the frame comprising legs, crossbars, and a receiving fitting for connecting the top plate and the frame, the receiving fitting being attached inside the crossbars such that its upper surface is disposed at a first position below the upper surface of the crossbars.
[0010] (2) A base having a top plate and the above-described frame.
Effects of the Invention
[0011] According to the present invention, it is possible to provide a frame and a base with a high degree of freedom in the shape of the top plate.

DETAILED DESCRIPTION OF THE INVENTION
[0013] Hereinafter, the table and the frame according to the embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a table. FIG. 2 is a perspective view showing an example of a frame. FIG. 3 is a partial cross-sectional view showing an example of a frame.
[0014] (Regarding the table) As shown in FIG. 1, the table 10 includes a top plate 11 and a frame 12. Examples of the table 10 include not only the table shown in FIG. 1 but also tables such as a kitchen table, a washstand, and a table. The table 10 may include a shelf (not shown).
[0015] Examples of the top plate 11 include a resin top plate that can be screwed, a wooden top plate, a stone top plate such as marble or artificial stone, a tiled top plate, and a metal top plate. When the top plate 11 is made of a material that is difficult to screw, such as a stone top plate, the top plate 11 uses an object having a surface material 11a located on the upper surface side and a structural material 11b located on the lower surface side. 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 12, and the top plate 11 is attached to the receiving fitting 12c with a screw 13b or the like in a state where the lower surface of the surface material 11a contacts the upper surface of the crosspiece 12a and the lower surface of the structural material 11b contacts the upper surface of the receiving fitting 12c.
[0016] This enables the top plate 11 to be securely fixed to the frame body 12. Since the structural member 11b is housed inside the crossbar portion 12a, it is not visible from the outside, and only the surface material 11a is visible from the outside. Therefore, the degree of freedom in the shape of the top plate 11 increases. For example, even when using a thin top plate such as marble with a thickness of 10 mm as the surface material 11a, since the structural member 11b can be housed inside the remaining portion 11a, it is possible to provide a refined and luxurious feeling and a sharp impression of the base.
[0017] For example, it is also possible to arrange the outer edge of the surface material 11a of the top plate 11 outside the outer edge of the crossbar portion 12a. When using thin wood as the top plate 11, similar to the above, an object having a surface material 11a made of wood and a structural member 11b located on the lower surface side may be used, or a top plate 11 made of thick wood may be prepared, the edge portion may be notched, and a swelling may be provided to process it into the shape of the thin surface material 11a and the structural member 11b.
[0018] (Regarding the frame body) As shown in FIG. 2, the frame body 12 includes a crossbar portion 12a, a leg portion 12b, and a receiving fitting 12c. As shown in FIG. 3, the receiving fitting 12c is an L-shaped member and has through holes into which screws (bolts) 13a and screws (wood screws) 12c can be inserted on each of the two surfaces. It is connected to the crossbar portion 12a by bolts 13a and connected to the top plate 11 (structural member 11b) by screws 12c. The receiving fitting 12c is attached inside the crossbar portion 12a so that its upper surface is disposed at a first position below the upper surface of the crossbar portion 12a. Thereby, even when using the top plate 11 including the surface material 11a and the structural member 11b, it is possible to connect the top plate 11 and the frame body 12 so that the structural member 11b is not visible from the outside.
[0019] As shown in the example of FIG. 3, if the length in the vertical direction between the upper surface of the crosspiece 12a and the upper surface of the receiving fitting 12c is made to coincide with the thickness of the structural material 11b, the lower surface of the surface material 11a can be brought into contact with the upper surface of the crosspiece 12a. However, if there is a concern about damage to the surface material 11a due to direct contact between the surface material 11a and the crosspiece 12a, in order to provide a gap between the surface material 11a and the crosspiece 12a, the length in the vertical direction between the upper surface of the crosspiece 12a and the upper surface of the receiving fitting 12c can be made shorter than the thickness of the structural material 11b to provide a slight gap. In this case, it is also possible to sandwich a cushioning material between the surface material 11a and the crosspiece 12a. In both of these cases, it can be said that the length in the vertical direction between the upper surface of the crosspiece 12a and the upper surface of the receiving fitting 12c is in a state of coinciding with the thickness of the structural material 11b. The same applies in the following description.
[0020] As the crosspiece 12a, as shown in the example of FIG. 3, a square pipe can be used. This is because the square pipe has sufficient strength and is lightweight. Note that an L-shaped angle can also be used as the crosspiece 12a. In this case, one of the two sides of the L-shaped angle will also serve as the receiving fitting 12c. However, it is preferable to use a square pipe in terms of the balance between strength and mass. Also, the crosspiece 12a is preferably connected to the leg portion 12b by welding or the like to form the frame body 12.
[0021] As shown in FIG. 2, it is preferable that the crosspiece 12a can be connected. That is, as the crosspiece 12a that constitutes the longitudinal direction of the frame body 12, one that connects the end crosspiece 18 and the middle crosspiece 19 can be used. Both ends of the middle crosspiece 19 are provided with connection portions having an outer surface shape that can slide on the inner surface of the end crosspiece 18. A screw hole is cut in the connection portion of the middle crosspiece 19, and a hole is provided at a position corresponding to this screw hole on the inner edge of the end crosspiece 18. By fixing with a screw (bolt) 30 or the like so that this hole and the screw hole coincide, the end crosspiece 18 and the middle crosspiece 19 can be connected. With such a configuration, by changing the length of the middle crosspiece 19, it becomes easy to assemble frame bodies 12 of various sizes. Also, the packaging size during transportation can be reduced, and the transportation cost can be lowered.
[0022] In the example shown in FIG. 2, two members obtained by welding one horizontal crossbar 17, two end crossbars 18, and two leg portions 12b are connected to two middle crossbars 19. In the example shown in the figure, since a horizontal crossbar 17 of about 700 mm is assumed, the horizontal crossbar 17 is integrally formed, but like the vertical crossbar, it may be configured to be connected.
[0023] As the leg portion 12b, in the example shown in FIG. 2, an example of a member welded to the outside of the corner of the crossbar 12a is illustrated, but the leg portion 12b can be of various shapes according to the design of the base 10. From the viewpoint of facilitating the assembly work and transportation, it is preferably welded to all or part of the crossbar 12a in advance.
[0024] In the example shown in FIG. 3, the receiving fitting 12c is an L-shaped member having through holes in each of the two planes and is configured to be connected to the crossbar 12a by bolts 13a. However, the bolts 13a may be connected to the crossbar 12a by other methods such as welding.
[0025] In the example shown in FIG. 3, the top plate 11 is attached to the receiving fitting 12c with screws 13b or the like. However, since the structure 11b is housed in the space surrounded by the inner edge of the crossbar 12a and the horizontal movement is restricted, it is not necessary to fix the top plate 11 to the receiving fitting 12c with screws 13b or the like.
[0026] (Regarding other frames) Hereinafter, with reference to FIGS. 4 to 8, examples of other frames will be described. FIG. 4 is a partial cross-sectional view showing an example of a receiving fitting. FIG. 5 is a partial cross-sectional view showing an example of a method of using the receiving fitting (an example when using a thick structural material). FIG. 6 is a partial cross-sectional view showing an example of a method of using the receiving fitting (an example when using a thin structural material). FIG. 7 is a partial cross-sectional view showing an example of a method of using the receiving fitting (an example in the case of a top plate that can be screwed). FIG. 8 is a partial cross-sectional view showing an example of a method of using the receiving fitting (an example in the case of a top plate that cannot be screwed).
[0027] As shown in FIG. 4, in this example, the receiving fitting 12d is used. The receiving fitting 12d is an L-shaped member having two facing members 12e and 12f, with one facing member 12e provided with one through-hole 14a and the other facing member 12f provided with two through-holes 14b and 14c. 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. And the distance L1 coincides with the relative distance in the vertical direction from the through-hole 15 in the cross-bar portion 12a to the upper surface of the cross-bar portion 12a. Hereinafter, the frame body 12 using this receiving fitting 12d will be described.
[0028] First, in the example shown in FIG. 5, the top plate 11 is composed of a surface material 11a and a relatively thick structural material 11b (such as a 18 mm structural plywood, etc.). And the cross-bar 12a and the receiving fitting 12d are connected at the position where the through-hole 15 and the through-hole 14b coincide. At this time, since the length in the vertical direction between the upper surface of the cross-bar portion 12a and the upper surface of the receiving fitting 12c coincides with the thickness of the structural material 11b, the top plate 11 is attached to the receiving fitting 12d and connected to the frame body 12 in a state where the lower surface of the surface material 11a contacts the upper surface of the cross-bar portion 12a and the lower surface of the structural material 11b contacts the upper surface of the receiving fitting 12d.
[0029] Next, in the example shown in FIG. 6, the top plate 11 is composed of a surface material 11a and a relatively thin structural material 11c (such as a 12 mm structural plywood, etc.). And the cross-bar 12a and the receiving fitting 12d are connected at the position where the through-hole 15 and the through-hole 14c coincide. At this time, the length in the vertical direction between the upper surface of the cross-bar portion 12a and the upper surface of the receiving fitting 12c coincides with the thickness of the structural material 11c. Thus, this receiving fitting 12d can be used even when the thickness of the structural material 11c is thin.
[0030] Next, in the example shown in FIG. 7, the top plate 11 is composed of a top plate that can be screwed. And the horizontal crossbar 12a and the receiving fitting 12d are connected at the position where the through hole 15 and the through hole 14a coincide. At this time, the upper surface of the crossbar portion 12a and the upper surface of the receiving fitting 12c coincide. In this way, this receiving fitting 12d can also be used in the case of the surface material 11a that can be screwed.
[0031] Next, in the example shown in FIG. 8, the top plate 11 is composed of a top plate that cannot be screwed. And on the upper surface of the horizontal crossbar 12a, an elastic material 16 such as resin is attached as a buffer material, and the top plate 11 is placed on this elastic material 16. In this way, if the receiving fitting is configured to be detachable from the horizontal crossbar 12a, a top plate that cannot be screwed can be placed.
[0032] In this way, for the frame body 12 using the receiving fitting 12d whose upper surface position can be variously changed, it can correspond to various top plate shapes. As a result, the parts can be made common, which contributes to reducing the inventory burden and also contributes to reducing the manufacturing cost.
[0033] As shown in FIG. 4, the receiving fitting 12d is provided with two through holes 14b and 14c having different distances from the corner in the facing material 12f, but the through hole may be a long hole extending in a direction away from the corner. Also, in the above example, a receiving fitting having an L-shaped cross-sectional shape was exemplified, but a receiving fitting having a U-shaped cross-sectional shape or a C-shaped cross-sectional shape may also be used. Further, the receiving fitting may be a short member or a long member (so-called angle).
[0034] FIG. 9 is a perspective view showing an example of a frame using a U-shaped receiving fitting. As shown in FIG. 9, the frame 12 includes a cross member 12a, legs 12b, and receiving fittings 12c and 12h. As shown in FIG. 3, the receiving fitting 12c is an L-shaped member having through holes into which bolts and screws can be inserted on each of two surfaces, and the receiving fitting 12h is a U-shaped member (angle) having through holes into which bolts and screws can be inserted on each of three surfaces. The receiving fittings 12c and 12h are both connected to the cross member 12a by bolts and connected to the top plate by screws. And the receiving fittings 12c and 12h are attached inside the cross member 12a so that their upper surfaces are disposed at a first position below the upper surface of the cross member 12a. Thereby, even when using the top plate 11 provided with the surface material 11a and the structural material 11b, it becomes possible to connect the top plate 11 and the frame 12 so that the structural material 11b is not visually recognized from the outside. The receiving fitting 12h is useful in cases where particularly high strength is required, such as for a long top plate.
