Further, the desk unit 1 may be provided with other optional members.

In the following description, the front side of the desk unit 1 as seen from the office worker working at the desk unit 1 will be referred to as the front, the rear side will be referred to as the rear, the left hand side will be referred to as the left, and the right hand side will be referred to as the right. That is, as shown in FIG. 1, the direction in which a pair of legs 10 of the desk 2, which will be described later, are spaced apart from each other is defined as the left-right direction, and the horizontal direction perpendicular to the left-right direction is defined as the front-back direction. Further, the direction of gravity (the direction along the normal line of the floor surface on which the desk 2 is placed) is defined as the vertical direction.

FIG. 2 is a perspective view of the desk 2. Further, FIG. 3 is an exploded perspective view of a part of the desk 2. The desk 2 is a fixture that provides a work surface on which electronic devices and the like used by an office worker can be placed.As shown in FIGS. 2 and 3, the desk 2 has a pair of legs 10 (support structure) and a ceiling. It includes a board 11, a curtain board 12, a wiring duct 13, a cover part 14, and a vertical wiring duct 15.

Each leg 10 includes a frame 10a formed by connecting four linear frames into a square frame, and an adjuster 10b connected to the lower end of the frame 10a. These legs 10 bring the adjuster 10b into contact with the floor surface and support the top plate 11 from below.
As shown in FIG. 2, these pair of legs 10 are spaced apart in the left-right direction with the frame-like frames 10a facing each other. That is, in this embodiment, the left-right direction is the direction in which the pair of legs 10 are separated. In addition, the leg body 10 can also adopt the structure provided with the panel which closes the opening part of the frame-shaped frame 10a, or the structure provided with a panel-shaped frame in place of the frame-shaped frame 10a, for example.

FIG. 4 is a schematic cross-sectional view of the frame 10a. As shown in this figure, the frame-like frame 10a has a frame base body 10a1 and a frame coating film 10a2.

The top plate coating film 11c is a coating coated on at least the upper surface 11b1 of the top plate base 11b. The surface of this top plate coating film 11c located on the opposite side from the top plate base 11b forms the top surface 11a (work surface) of the top plate 11. As shown in FIG. 5, the top plate coating film 11c is a multilayered coating film formed by laminating a thermal sensation adjusting layer 11c1 (functional coating layer) and a colored coating layer 11c2.

The thermal sensation adjusting layer 11c1 is formed of a paint having a lower heat transfer coefficient than the paint forming the colored paint layer 11c2, and is a paint layer having a lower heat transfer coefficient than the colored paint layer 11c2. Furthermore, in this embodiment, the thermal sensation adjustment layer 11c1 is a transparent layer that can transmit light.

Such a thermal sensation adjustment layer 11c1 can be formed of, for example, a transparent paint containing hollow particles whose outer shell is made of silica and which has a space inside. It is also possible to form the thermal sensation adjusting layer 11c1 with a paint containing at least one of hollow particles, hollow fibers, and porous particles. It is also possible to form the thermal sensation adjusting layer 11c1 with a paint containing a crosslinked poly-γ-glutamic acid, a resin, and a solvent.

It is also possible to form the thermal sensation adjusting layer 11c1 with a paint containing hygroscopic heat-generating fine particles. Note that the thermal sensation adjustment layer 11c1 is not limited to a structure including hollow particles, and may be formed, for example, by a paint layer in which a large number of voids are formed.

The colored paint layer 11c2 is a paint layer that covers the thermal sensation adjustment layer 11c1 from the side opposite to the top plate base 11b and is visible from the outside of the top plate 11, and determines the color tone of the top plate 11. The surface of this colored paint layer 11c2 located on the opposite side from the top plate base 11b forms the upper surface 11a of the top plate 11. The colored paint layer 11c2 is formed by drying the colored paint applied to the surface of the temperature sensation adjustment layer 11c1.

The thickness dimensions of the thermal sensation adjusting layer 11c1 and the colored paint layer 11c2 are approximately the same. Further, the thickness of each of the thermal sensation adjusting layer 11c1 and the colored paint layer 11c2 is approximately the same as that of the frame coating film 10a2. That is, in this embodiment, the top plate coating film 11c has a two-layer structure, which has more layers than the single-layer frame coating film 10a2, and the thickness dimension of the top plate coating film 11c is equal to the thickness of the frame coating film 10a2. It is said to be about twice the size. That is, in this embodiment, the work surface of the top plate 11 is kept away from the metal top plate base 11b, and heat transfer between a hand or the like touching the top plate 11 and the top plate base 11b is suppressed.

Such a top plate coating film 11c does not necessarily have to have two paint layers, and it is also possible to adopt a configuration in which the number of paint layers is three or more layers. However, even when the number of laminated paint layers in the top plate coating film 11c is increased, the number of laminated paint layers forming the top plate coating film 11c is equal to the number of laminated paint layers forming the frame coating film 10a2. More than numbers.

As shown in FIGS. 1 to 3, the curtain plate 12 is a plate-shaped member that connects the rear end of one leg 10 and the rear end of the other leg 10. As shown in FIGS.

Subsequently, in the top plate forming step, as shown in FIG. 6(b), a thermal sensation adjustment layer forming step is performed in which a thermal sensation adjustment layer 11c1 is formed on the upper surface 11b1 of the top plate base 11b. Here, the thermal sensation is adjusted by applying a paint (a different paint from the forming material of the colored paint layer 11c2) to be the forming material of the thermal sensation adjusting layer 11c1 onto the upper surface 11b1 of the top plate base 11b, and then drying the paint. A layer 11c1 is formed. That is, in the thermal sensation adjustment layer forming step, the thermal sensation adjustment layer 11c1 having a lower thermal conductivity than the other paint layers (in this embodiment, the colored paint layer 11c2) forming the top plate coating film 11c is formed.

Subsequently, in the top board forming step, as shown in FIG. 6(c), a colored paint layer forming step is performed in which a colored paint layer 11c2 is formed so as to cover the thermal sensation adjustment layer 11c1 from the side opposite to the top board base 11b. . Here, the colored paint layer 11c2 is formed by applying a paint serving as a material for forming the colored paint layer 11c2 to the temperature sensation adjusting layer 11c1 so as to be laminated thereon, and then drying the paint. That is, in the colored paint layer forming step, a colored paint layer 11c2 that covers the thermal sensation adjusting layer 11c1 from the side opposite to the top plate base 11b and is visible from the outside of the top plate 11 is formed.

Through these thermal sensation adjustment layer forming steps and colored paint layer forming steps, a top plate coating film 11c consisting of a plurality of laminated paint layers is formed. That is, in the method for manufacturing the desk 2, the top plate coating film 11c is formed by applying the paint twice. In these thermal sensation adjusting layer forming step and colored paint layer forming step, paint is laminated and applied on at least the upper surface 11b1 of the metal top plate base 11b to form a colored paint layer 11c2 and a thermal sensation adjusting layer 11c1. This constitutes a top plate coating layer forming step for forming the top plate coating film 11c.

As shown in FIG. 7A, in the leg forming step, a frame base 10a1 having a predetermined shape is formed by processing a sheet metal. Note that the frame base body 10a1 does not need to be assembled into a frame shape here, and is formed by dividing the frame base body 10a1 into four rod-shaped frames.

Subsequently, in the leg forming step, as shown in FIG. 7(b), a frame coating film forming step is performed in which a frame coating film 10a2 is formed on the surface of the frame base body 10a1. Here, the frame coating film 10a2 is formed by coating the surface of the frame base body 10a1 with a paint serving as a material for forming the frame coating film 10a2, and then drying the paint. That is, in the frame coating film forming step, a frame coating film 10a2 that is in contact with the surface of the frame base body 10a1 and visible from the outside of the leg body 10 is formed. Thereafter, the leg body 10 is formed by assembling the disassembled frame base body 10a1 and attaching the adjuster 10b. Note that the adjuster 10b may be attached after the legs 10 and the top plate 11 are assembled.

FIG. 8 is a perspective view schematically showing a part of the assembly process. In the assembly process, the legs 10 formed in the leg formation process described above and the top plate 11 formed in the top plate formation process described above are assembled using fasteners or the like (not shown). In addition, in the assembly process, in addition to the legs 10 and the top plate 11, the curtain plate 12, the wiring duct 13, the cover part 14, and the vertical wiring duct 15 may be assembled. The desk 2 is completed through such an assembly process.

In the top plate forming process of this embodiment, paint is laminated and applied on at least the upper surface of the metal top plate base 11b to form a colored paint layer 11c2 that is visible from the outside of the top plate 11, and a colored paint layer 11c2. It has a top plate coating film forming step of forming a top plate coating film 11c that is disposed between the top plate base body 11b and includes a colored paint layer 11c2 and a functional paint layer formed of a different paint.

According to such a top plate forming process, the top plate coating film 11c includes a colored paint layer 11c2 that is visible from the outside and a functional paint layer disposed between the colored paint layer 11c2 and the top plate base 11b. It is possible to manufacture the top plate 11 having the following properties. Therefore, functions different from color adjustment are carried out by the functional paint layer, and there is no need to add components for functions different from color adjustment to the colored paint layer 11c2. Therefore, according to such a top plate forming process, it is possible to prevent a change in the color tone of the top plate 11 and provide the paint layer of the top plate 11 with a function different from color adjustment.

Further, in the top plate forming step in this embodiment, a thermal sensation adjustment layer 11c1 having a lower thermal conductivity than the colored paint layer 11c2 is formed as a functional paint layer. Therefore, the top plate 11 including the thermal sensation adjustment layer 11c1 can be formed, suppressing the feeling of coldness or heat of the top plate base 11b by the office worker, etc. Discomfort when touched can be reduced.

Further, in the top plate forming step in this embodiment, a thermal sensation adjusting layer 11c1 made of a transparent layer that can transmit light is formed as a functional paint layer. Therefore, even if the thickness of the colored paint layer 11c2 is small, the color tone of the functional paint layer (thermal sensation adjustment layer 11c1) is prevented from being visible to outsiders through the colored paint layer 11c2. , it is possible to prevent the functional paint layer (thermal sensation adjustment layer 11c1) from affecting the color tone of the top plate 11.

Further, the method for manufacturing the desk 2 as described above includes a top plate forming step of forming the top plate 11 with the upper surface 11a serving as a work surface, and a leg forming step of forming the legs 10 that support the top plate 11. , and an assembly step of assembling the top plate 11 and the legs 10. Therefore, it is possible to manufacture the desk 2 in which the paint layer of the top plate 11 has a function different from color adjustment while preventing changes in the color tone of the top plate 11.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above embodiments. The various shapes and combinations of the constituent members shown in the embodiments described above are merely examples, and can be variously changed based on design requirements and the like without departing from the spirit of the present invention.

For example, in the above embodiment, the top plate coating film 11c has a structure in which the thermal sensation adjustment layer 11c1 and the colored paint layer 11c2 are laminated. However, the present invention is not limited thereto. FIG. 9 is a schematic cross-sectional view showing a modification of the top plate coating film 11c. For example, as shown in FIG. 9(a), a configuration may be adopted in which a cushion layer 11c3 (functional paint layer) that provides cushioning properties as a function to the top plate 11 is provided in place of the thermal sensation adjustment layer 11c1. It is possible. Such a cushion layer 11c3 is, for example, a layer whose elastic modulus is smaller than that of the colored paint layer 11c2, and is formed by applying paint. Further, as shown in FIG. 9(b), it is also possible to adopt a configuration including a hard layer 11c4 that provides a function to improve the hardness of the top plate 11 in place of the thermal sensation adjustment layer 11c1. Such a hard layer 11c4 (functional paint layer) is a layer having, for example, a larger elastic modulus than the colored paint layer 11c2, and is formed by applying a paint.

Even with the configurations shown in FIGS. 9(a) and 9(b), the top plate coating film 11c can be made thicker than the frame coating film 10a2, and the top plate coating film 11c can be made thicker than the frame coating film 10a2. The distance dimension to the base body 11b can be made larger than the distance dimension from the surface of the frame coating film 10a2 to the frame base body 10a1. Therefore, even with the configurations shown in FIGS. 9(a) and 9(b), it is possible to prevent the office worker from feeling the coldness or heat of the top plate base 11b, and to prevent the office worker from feeling the coldness or heat of the top plate base 11b.
