[0008] 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 comprises a pair of left and right front columns 2·2, a pair of left and right rear columns 3·3, front and rear connecting members 4 that connect the upper and lower ends of the front columns 2 and rear columns 3 located on the same side, a rear connecting member 5 that connects the upper and lower ends of the rear columns 3·3, a front connecting member 6 that connects the upper ends of the front columns 2·2, and a tabletop 7 and a shelf 8 supported by the front columns 2·2 and rear columns 3·3.

[0009] The front column 2 and rear column 3 are elongated rectangular prism-shaped members. The front and rear connecting members 4, rear connecting member 5, and front connecting member 6 are elongated 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 column 2 and rear column 3, which are arranged vertically, by welding, screws, bolts and nuts, etc. This configuration increases the overall rigidity of the frame that makes up the desk 1.

[0010] Adjusters 9 are provided at the lower ends 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 adjusters 9 from the front and rear columns 2 and 3.

[0011] In the desk 1, as shown in FIG. 2, side plates 11·11 are assembled to the front columns 2 and the rear columns 3 on the same side on the left and right. Further, as shown in FIG. 3, a back plate 12 and braces 13·13 are assembled to the rear columns 3·3. Further, a net panel 14 is spanned as a ceiling member over the front and rear connecting members 4·4 on the left and right.

[0012] As shown in FIGS. 1 to 3, in the desk 1 according to the present embodiment, the side plates 11 and the back plate 12 are made of plain plate members. Note that either or all of the side plates 11 and the back plate 12 can be made of perforated boards or net panels. Further, with respect to the front and rear connecting members 4·4, a configuration can be adopted in which another plate member is provided as a ceiling member instead of the net panel 14.

[0013] In the desk 1 according to the present embodiment, the front columns 2, the rear columns 3, the front and rear connecting members 4, the rear side connecting members 5, and the front side connecting members 6 are each made of steel members. This makes it possible to further increase the rigidity of the desk 1. Note that for all or part of the above members, other materials such as metal materials other than steel, resin materials, wood, carbon materials, etc. can be adopted.

[0014] In the desk 1 according to the present embodiment, a plurality of front and rear connecting members 4 and rear side connecting members 5 are arranged vertically. This makes it possible to increase the rigidity of the desk 1. Note that a configuration can be adopted in which either the front and rear connecting members 4 or the rear side connecting members 5 are provided only at one of the upper and lower ends of the front columns 2 and the rear columns 3.

[0015] In the desk 1, the front columns 2 and the rear columns 3 are formed in a U-shaped cross section perpendicular to the longitudinal direction, and the front columns 2 and the rear columns 3 on the same side on the left and right are arranged facing each other with the concave sides. And on both left and right side surfaces of the front columns 2 and the rear columns 3, engaged holes 2a·3a, which are a large number of holes, are formed along the vertical direction.

[0016] The engaged holes 2a and 3a in the front column 2 and the rear column 3 are used when assembling the top plate 7 and the shelf 8. Note that the top plate 7 and the shelf 8 may be directly supported by the front column 2 and the rear column 3 using the engaged holes 2a and 3a, or may be indirectly supported by the front column 2 and the rear column 3 by engaging other members with the engaged holes 2a and 3a.

[0017] In the desk 1 according to the present embodiment, the top plate 7 is assembled to the front column 2 and the rear column 3 via the top plate bracket 21 and the beam member 22. Specifically, as shown in FIGS. 2 and 5, the engaging portions of the top plate bracket 21 are engaged with the engaged holes 2a and 3a of the front column 2 and the rear column 3 on the same side on the left and right. Then, the beam member 22 is bridged over the pair of left and right top plate brackets 21, and the top plate 7 is fixed to the upper surface of the beam member 22. A wiring duct 23 is provided on the lower surface of the top plate 7.

[0018] In the desk 1 according to the present embodiment, above the top plate 7, the shelf 8 is supported by the front column 2 and the rear column 3. In the present embodiment, the shelf 8 is composed of a shelf bracket 31, a shelf board 32, a locking member 33, and a shaft 34 which is a fall prevention part.

[0019] As shown in FIGS. 2 and 5, the engaging portions of the shelf bracket 31 are engaged with the engaged holes 2a and 3a of the front column 2 and the rear column 3 on the same side on the left and right. Then, the shelf 8 is formed by bridging the shelf board 32 over the pair of left and right shelf brackets 31.

[0020] In the shelf bracket 31, a locking member 33 which is a plate-like member for locking the shaft 34 is assembled to the front side of the shelf board 32. As shown in FIG. 6, a long hole 33a is opened in the middle part of the locking member 33 along the vertical direction. Further, a semi-circular notch 33b is formed at the upper end of the locking member 33.

[0021] As shown in Figures 2, 4, and 6(a), the shaft 34 is a rod-shaped member positioned in front of the upper side of the shelf 32 to prevent items placed on the upper surface of the shelf 32 from falling from the front end of the shelf 32. As shown in Figure 6, connecting portions 34b are formed at both the left and right ends of the shaft 34, extending in a direction perpendicular to the shaft 34. At the tip of the connecting portion 34b, an engaging portion 34a is formed facing inward in the longitudinal direction of the shaft 34.

[0022] The engaging portion 34a formed on the shaft 34 engages with the locking member 33 when inserted through the elongated hole 33a of the locking member 33. As a result, the shaft 34 is locked to the locking member 33 via the connecting portion 34b. In this way, the connecting portion 34b functions as a support member that supports the shaft 34.

[0023] The connecting portion 34b is rotatable in the front-rear direction around the engaging portion 34a. That is, the connecting portion 34b is rotatable relative to the shelf plate 32 around a rotation axis (the line connecting the engaging portions 34a and 34a) oriented in the horizontal direction.

[0024] When using the shelf board 32, the shaft 34 is locked into the notch 33b of the locking member 33 as shown in Figure 6(a). This results in the shaft 34 being in a restrained position above the shelf board 32.

[0025] When placing an item on or removing an item from the shelf 32, the shaft 34 is lifted as shown by the dashed line in Figure 6(b), and then the shaft 34 and the connecting part 34b are rotated forward. This causes the shaft 34 to be in the released position, which is below the shelf 32, as shown in Figure 6(b).

[0026] As described above, in the desk 1 according to this embodiment, the shaft 34 is displaceable between a restraining position located above the shelf 32 and a release position located below the restraining position by the rotation of the connecting portion 34b. In this way, in the desk 1, the restraint on items falling from the shelf 32 can be released by displacing the shaft 34.

[0027] In this invention, as shown in the modified desk 1A in Figure 7, other optional members can be attached to the front column 2 and rear column 3. In desk 1A, long magazine racks 41-41 are attached to the rear columns 3-3 on the back side. In this modified example, the rigidity of desk 1A is ensured by attaching two long magazine racks 41 to the rear columns 3-3 instead of braces 13-13. In addition, in desk 1A, short magazine racks 42 and a whiteboard 43 are attached to the front column 2 and rear column 3 on the side using engagement holes 2a-3a.

[0028] As described above, in the desk 1 according to this embodiment, the tabletop 7 and shelf 8 are directly or indirectly supported by the front column 2 and rear column 3 using engagement holes 2a and 3a, which are holes opened in the front column 2 and 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 upper surface of the shelf board 32 from falling from the front end of the shelf board 32. As a result, the desk 1 can be connected to other desks or shelves, and the height of the tabletop 7 can be adjusted by using the engagement holes 2a and 3a opened in the front column 2 and rear column 3.

[0029] Specifically, as shown in Figures 8 and 9, the front column 2 and rear column 3 of the desk 1 according to this embodiment are formed in a U-shape with a cross-section perpendicular to the longitudinal direction. By using the engagement holes 2a and 3a opened on both sides of the front column 2 and rear column 3, the front column 2 and rear column 3 can be easily shared between adjacent desks 1 and 1. In other words, desk 1 can be easily connected to other desks 1. It is also possible to provide a shelf without a top plate 7 instead of another desk 1 adjacent to desk 1.

[0030] Furthermore, in desk 1, by providing a shelf 8 above the tabletop 7, the space above the tabletop 7 can be effectively utilized. In addition, the shaft 34, which is a fall prevention part, makes it possible to prevent items placed on the upper surface of the shelf 32 from falling.

[0031] Furthermore, in the desk 1 according to this embodiment, as shown in Figure 5, the front-to-back width of the shelf 32 is shorter than the front-to-back 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 of the shelf 32.

[0032] Furthermore, in the desk 1 according to this embodiment, the fall prevention mechanism in the shelf 8 is made of a shaft 34, which is a rod-shaped member extending in the left-right direction. This allows for a simple construction of the fall prevention mechanism in the shelf 8 of the desk 1.

[0033] Furthermore, in the desk 1 according to this embodiment, the shaft 34 is supported via a connecting portion 34b, which is a support member. The connecting portion 34b is rotatable relative to the shelf 32 about a rotation axis oriented horizontally. In addition, the shaft 34 is displaceable between a restraining position located above the shelf 32 and a release position located below the restraining position by the rotation of the connecting portion 34b. In this way, in the desk 1, the fall restraint can be released by displacing the shaft 34.

[0034] Furthermore, in the desk 1 according to this embodiment, the shelf 8 includes a shelf bracket 31 that spans between the front column 2 and the rear column 3 located on the same side, and the shelf board 32 is supported by the shelf bracket 31. This makes it easy to attach and detach the shelf board 32 by attaching and detaching the shelf bracket 31 to the front column 2 and the rear column 3.

[0035] [Other variations] The above embodiment can be modified as appropriate, as shown in the following modifications. Each modification may be applied in combination with other modifications, provided that no inconsistencies arise.

[0036] In the desk according to the present invention, the front-to-back width of the shelf board can be configured to be approximately the same as the front-to-back width of the tabletop. Furthermore, the tabletop and shelf board can be directly assembled to the front and rear columns without using brackets.

[0037] Furthermore, the fall prevention mechanism on the shelf can be made of a shape other than a shaft. It is also possible to configure the fall prevention mechanism so that it does not displace. Additionally, the fall prevention mechanism can be made to slide, allowing it to move between a suppressed position and a released position. [Explanation of Symbols]
