Description

[Detailed description of the invention] [Industrial application field] The present invention allows a long bookshelf to protrude above the top plate or to the front of the top plate on one side of the top plate. Regarding the unit desk.

[Conventional technology]

As shown in FIG. 5, a unit desk in which the upper half of a vertically long bookshelf A projects upward from one side of a top plate B is well known.

In this type of unit desk, a part of the top board B is cut into the bookshelf A, so the occupied area is smaller than when a desk and a bookshelf with the same planar dimensions are placed side by side. It is widely used because it significantly reduces

[Problem that the invention attempts to solve]

However, in conventional unit desks, since the area of the top plate B is constant, in order to increase the desk area, it is necessary to place a separately prepared auxiliary table or the like against the top plate B, which is uneconomical.

[Means for solving problems]

The purpose of the present invention is to provide a unit desk that uses a bookshelf that protrudes upward from the top plate to greatly increase the actual usable area of the top plate, if necessary. In a unit desk in which one side end is supported by a fixed shelf at the middle part in the height direction of a vertically elongated bookshelf, the bookshelf is supported by a top plate, a bottom plate, a side plate and a fixed shelf board in the middle part of equal thickness. The storage space has square storage space sections of the same size on the top and bottom, and is characterized in that locking sections for attaching shelf boards are provided on the left and right and top and bottom opposing surfaces of the storage space sections.

〔Example〕

In FIG. 1, reference numeral 1 denotes a top plate, whose right end is supported by a drawer sleeve 2, and its left end is supported by a fixed shelf board 4 in the center of a bookshelf 3.

As shown in FIG. 2, the bookshelf 3 has a frame formed by connecting the opposing surfaces of the side ends of a top plate 5 and a bottom plate 6 with side plates 7, 7, and closes the rear surface of the frame with a rear plate 8. A fixed shelf board 4 is installed at the center in the height direction of the shelves 7, 7, and a movable shelf board 10 with a drawer 9 and a movable shelf board 11 without a drawer are installed above and below the fixed shelf board 4, respectively.

That is, protrusions 12, 12 are provided at the front ends of the upper and lower end surfaces of the side plates 7, 7, and these are provided at the front and rear of the lower surface of the side ends of the top plate 5, and at the front and rear of the upper surface of the side ends of the bottom plate 6. It is tightly fitted into the engagement holes 13, 13. Note that the engagement hole in the top plate 5 is not shown in the figure.

Further, in the center of the opposing surfaces of the side plates 7, 7, protruding plugs 14, 1 protruding from the front and rear side end surfaces of the fixed shelf board 4 are provided.
Above and below the engagement holes 15, 15 into which the movable shelf boards 10, 11 are fitted, there are a number of engagement holes 17 into which support pieces 16 for supporting the front and rear parts of the movable shelf boards 10, 11 can be fitted, respectively. It's open.

Engagement holes 18 and 19 into which the support pieces 16 can be fitted are also formed in the front and rear portions of the opposing surfaces of the top plate 5 and the fixed shelf plate 4, as well as the fixed shelf plate 4 and the bottom plate 6.

A receiving piece 20 having a shape capable of supporting the front edge of the fixed shelf board 4 is attached to the lower surface of the top plate 1 slightly to the right of the left end.

As shown in FIG. 3, the height h from the bottom surface of the bottom plate 6 to the top surface of the fixed shelf board 4 and the height h from the bottom surface of the fixed shelf board 4 to the top surface of the top surface board 5 are both is equal to the height of the bottom left edge of .

The width b of the frame body, that is, the outer dimension of the side plates 7, 7 is equal to the height h of the fixed shelf board 4.

Top plate 5, bottom plate 6, side plate 7 and fixed shelf board 4
All plate thicknesses t are equal.

Therefore, the two upper and lower storage spaces partitioned by the fixed shelf board 4 form squares of the same size.

Since the dimensions and shape of the bookshelf 3 are as described above, as shown in FIG. If you make it stick out in front of 1,
An L-shaped desk with a wide top area can be formed.

At this time, a movable shelf board 10 or 11 can be attached between the top board 5 and the fixed shelf board 4 and between the fixed shelf board 4 and the bottom board 6 in the bookshelf 3 that is tilted forward.
