First, a desk 1 according to one embodiment of the present invention will be described with reference to Figures 1 to 5. As shown in Figures 1 to 3, the desk 1 according to this embodiment includes a pair of left and right front columns 2, a pair of left and right rear columns 3, a front and rear connecting member 4 connecting the upper and lower ends of the front columns 2 and rear columns 3 located on the same left and right side, a rear connecting member 5 connecting the upper and lower ends of the rear columns 3, a front connecting member 6 connecting the upper ends of the front columns 2, 2, and a top plate 7 and a shelf 8 supported by the front columns 2 and the rear columns 3.

The front and rear columns 2 and 3 are long rectangular column-shaped members. The front and rear connecting members 4, rear connecting member 5, and front connecting member 6 are long plate-shaped members. The front and rear connecting members 4, rear connecting member 5, and front connecting member 6 are firmly attached to the front and rear columns 2 and 3, which are arranged vertically, by welding, screwing, bolts and nuts, etc. This increases the overall rigidity of the frame that constitutes the desk 1.

An adjuster 9 is provided at the lower end of each of the front and rear columns 2 and 3. The user of the desk 1 can adjust the height of the desk 1 from the floor by adjusting the extension length of the adjuster 9 from the front and rear columns 2 and 3.

As shown in Figure 2, in the desk 1, side panels 11, 11 are attached to the front column 2 and rear column 3 on the same left and right side. Also, as shown in Figure 3, a back panel 12 and braces 13, 13 are attached to the rear columns 3, 3. Also, a mesh panel 14 is hung as a ceiling member between the front and rear connecting members 4, 4 on the left and right.

As shown in Figures 1 to 3, in the desk 1 according to this embodiment, the side panels 11 and the back panel 12 are made of plain plate-like materials. It is also possible for any or all of the side panels 11 and the back panel 12 to be perforated boards or mesh panels. It is also possible to provide other plate-like materials as ceiling members instead of the mesh panels 14 for the front and rear connecting members 4, 4.

In the desk 1 according to this embodiment, the front column 2, rear column 3, front and rear connecting member 4, rear connecting member 5, and front connecting member 6 are each made of steel. This makes it possible to further increase the rigidity of the desk 1. It is also possible to use other materials, such as metal materials other than steel, resin materials, wood, and carbon materials, for all or part of the above-mentioned components.

In the desk 1 according to this embodiment, multiple front and rear connecting members 4 and multiple rear connecting members 5 are arranged vertically. This increases the rigidity of the desk 1. It is also possible to provide either the front and rear connecting members 4 or the rear connecting members 5 on only one of the upper and lower ends of the front column 2 and the rear column 3.

In the desk 1, the front and rear columns 2 and 3 are U-shaped in cross section perpendicular to the longitudinal direction, and the front and rear columns 2 and 3 on the same left and right side are arranged with their concave sides facing each other. Numerous engaging holes 2a and 3a are formed in the vertical direction on both the left and right side surfaces of the front and rear columns 2 and 3.

The engaged holes 2a and 3a in the front and rear columns 2 and 3 are used when assembling the top plate 7 and shelf 8. The top plate 7 and shelf 8 may be directly supported by the front and rear columns 2 and 3 using the engaged holes 2a and 3a, or may be indirectly supported by the front and rear columns 2 and 3 by engaging other members with the engaged holes 2a and 3a.

In the desk 1 according to this embodiment, the top plate 7 is attached to the front and rear columns 2 and 3 via the top plate brackets 21 and the beam members 22. Specifically, as shown in Figs. 2 and 5, the engaging portions of the top plate brackets 21 engage with the engaging holes 2a and 3a of the front and rear columns 2 and 3 on the same left and right side. Then, the beam members 22 are stretched across the pair of left and right top plate brackets 21, and the top plate 7 is fixed to the upper surface of the beam members 22. A wiring duct 23 is provided on the underside of the top plate 7.

In the desk 1 according to this embodiment, a shelf 8 is supported above the top board 7 by the front column 2 and the rear column 3. In this embodiment, the shelf 8 is composed of a shelf bracket 31, a shelf board 32, a locking member 33, and a shaft 34 that acts as a fall prevention part.

As shown in Figures 2 and 5, the engaging portion of the shelf bracket 31 engages with the engaging holes 2a, 3a of the front column 2 and rear column 3 on the same left and right side. Then, the shelf board 32 is spanned across the pair of left and right shelf brackets 31 to form the shelf 8.

In the shelf bracket 31, a locking member 33, which is a plate-shaped member that locks the shaft 34, is attached to the front side of the shelf board 32. As shown in FIG. 6, a long hole 33a is opened in the middle of the locking member 33 along the vertical direction. In addition, a semicircular cutout portion 33b is formed in the upper end portion of the locking member 33.

As shown in Figures 2, 4, and 6(a), the shaft 34 is a rod-shaped member that is disposed in front of the upper side of the shelf board 32 to prevent items placed on the upper surface of the shelf board 32 from falling off the front end side of the shelf board 32. As shown in Figure 6, linking portions 34b extending in a direction perpendicular to the shaft 34 are formed at both left and right ends of the shaft 34. An engagement portion 34a is formed at the tip of the linking portion 34b toward the inside in the longitudinal direction of the shaft 34.

The engaging portion 34a formed on the shaft 34 is inserted into the long hole 33a of the locking member 33 and engaged with the locking member 33. As a result, the shaft 34 is locked to the locking member 33 via the linking portion 34b. In this way, the linking portion 34b functions as a support member that supports the shaft 34.

The linking portion 34b can rotate in the front-rear direction around the engaging portion 34a. In other words, the linking portion 34b can rotate relative to the shelf board 32 around a horizontal rotation axis (a line connecting the engaging portions 34a and 34a).

When the shelf 32 is in use, the shaft 34 is engaged with the notch 33b of the engaging member 33 as shown in FIG. 6(a). This places the shaft 34 in a restraining position in which it is positioned above the shelf 32.

When placing an item on the shelf 32 or removing an item from the shelf 32, the shaft 34 is lifted as shown by the two-dot chain line in FIG. 6(b), and then the shaft 34 and the linking portion 34b are rotated forward. This places the shaft 34 in a release position below the shelf 32 as shown in FIG. 6(b).

As described above, in the desk 1 according to this embodiment, the shaft 34 can be displaced between a restraining position in which the shaft 34 is positioned above the shelf 32 and a release position in which the shaft 34 is positioned below the restraining position by rotating the linking portion 34b. In this way, in the desk 1, the prevention of items from falling from the shelf 32 can be released by displacing the shaft 34.

In the present invention, as in the modified desk 1A shown in FIG. 7, other optional components can be attached to the front and rear columns 2 and 3. In the desk 1A, long magazine racks 41 are attached to the rear columns 3 on the rear side. In this modified example, two long magazine racks 41 are attached to the rear columns 3 instead of the braces 13, ensuring the rigidity of the desk 1A. In addition, in the desk 1A, a short magazine rack 42 and a whiteboard 43 are attached to the front and rear columns 2 and 3 on the side using the engaging holes 2a and 3a.

As described above, in the desk 1 according to this embodiment, the top plate 7 and shelf 8 are directly or indirectly supported by the front column 2 and the rear column 3 using the engaging holes 2a and 3a, which are holes opened in the front column 2 and the rear column 3. The shelf 8 is composed of a shelf board 32 and a shaft 34, which is a fall prevention part that prevents items placed on the top surface of the shelf board 32 from falling from the front end side of the shelf board 32. This makes it possible for the desk 1 to be connected to another desk or shelf body and to adjust the height of the top plate 7 by using the engaging holes 2a and 3a opened in the front column 2 and the rear column 3.

Specifically, as shown in Figures 8 and 9, the front and rear columns 2 and 3 of the desk 1 according to this embodiment are formed with a U-shaped cross section perpendicular to the longitudinal direction. By using the engaging holes 2a and 3a opened on both side surfaces of the front and rear columns 2 and 3, the front and rear columns 2 and 3 can be easily shared by adjacent desks 1 and 1. In other words, the desk 1 can be easily connected to other desks 1. It is also possible to provide a shelf body without a top plate 7 in place of the other desk 1 adjacent to the desk 1.

In addition, by providing a shelf 8 above the top plate 7 of the desk 1, the space above the top plate 7 can be effectively utilized. Furthermore, the shaft 34, which acts as a fall prevention part, can prevent items placed on the top surface of the shelf plate 32 from falling.

In addition, as shown in FIG. 5, in the desk 1 according to this embodiment, the front-to-rear width of the shelf 32 is shorter than the front-to-rear width of the tabletop 7, and the front end of the shelf 32 is positioned further back than the front end of the tabletop 7. This makes it easier for the user of the desk 1 to see the top side of the shelf 32.

In addition, in the desk 1 according to this embodiment, the fall prevention unit in the shelf 8 is configured with a shaft 34, which is a rod-shaped member extending in the left-right direction. This allows the fall prevention unit to be easily configured in the shelf 8 of the desk 1.

In addition, in the desk 1 according to this embodiment, the shaft 34 is supported via the linking portion 34b, which is a support member. The linking portion 34b is rotatable relative to the shelf 32 around a horizontal axis of rotation. Furthermore, the shaft 34 can be displaced between a restraining position in which it is positioned above the shelf 32 and a release position in which it is positioned below the restraining position by rotating the linking portion 34b. In this way, in the desk 1, the fall restraint can be released by displacing the shaft 34.

In addition, in the desk 1 according to this embodiment, the shelf 8 includes a shelf bracket 31 that is bridged between the front column 2 and the rear column 3 that are located on the same side, and the shelf board 32 is supported by the shelf bracket 31. This allows the shelf board 32 to be easily attached/detached by attaching/detaching the shelf bracket 31 to/from the front column 2 and the rear column 3.

[Other Modifications]
The above embodiment can be modified as appropriate as shown in the following modifications. Each modification may be applied in combination with other modifications as long as no contradiction occurs.

In the desk of the present invention, it is possible to configure the front-to-rear width of the shelf board to be approximately the same as the front-to-rear width of the tabletop. It is also possible to configure the tabletop and shelf board to be directly attached to the front and rear columns without using brackets.

The fall suppression part on the shelf can also be shaped in a way other than a shaft. It is also possible to configure the fall suppression part so that it does not displace. It is also possible for the fall suppression part to be displaceable between the suppression position and the release position by sliding.
