[Prior Art]

 This type of desk with an upper shelf device (so-called learning desk) is known in design gazettes (Registration Nos. 3381 07 and 569703), and the upper shelf device is installed on the left and right sides of the upper rear portion of the top of the desk. It is disclosed that a pair of left and right side plates to be installed and an upper shelf plate and a lower shelf plate that are horizontally mounted between the inner surfaces of the left and right side plates are provided, and that the lower shelf side of the upper shelf plate is provided with a lighting fixture having left and right lengths. There is.

[0003]

[Problems to be solved by the device]

 In this way, in the conventional upper shelf device in the learning desk, the front edge of the upper shelf plate is formed in a backward convex curved shape at the left and right central parts, and at least the left and right central parts of the lighting fixtures provided on the lower surface side of the upper shelf plate are formed. It was designed so that the illumination light from could be emitted upwards and the letters on the back of books placed on the upper shelf could be seen easily.

Incidentally, as for the lower shelf, the front edge of the lower shelf has been formed in parallel with the rear edge of the top plate, just like an ordinary shelf for mounting books and notebooks. Therefore, if the depth dimension of the lower shelf board is set to be large so that a large-sized book can be placed, the area of the rear portion of the top plate of the desk to be used decreases, and conversely if the depth dimension of the lower shelf board is reduced, There was the inconvenience that large format books could not be placed.

An object of the present invention is to solve the above-mentioned conventional drawbacks and to provide a convenient desk for learning.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention mounts an upper shelf device which is detachably mounted on a rear portion of a top surface of a desk, in a substantially horizontal shape between left and right side plates standing on the top plate. It consists of a lower shelf and an upper shelf, and lighting fixtures are installed on the lower front of the upper shelf in the left and right directions, while the plan view of the lower shelf is such that the front edge of the lower shelf is at the center. The depth dimension is shortened so that it approaches the rear part of the plate, and the depth dimension is large so as to project to the front edge side of the side plate at the parts near the inner surfaces of the left and right side plates, and the depth dimension decreases toward the central part. It is formed in an inclined shape like this.

[0007]

【Example】

 Next, an embodiment embodying the present invention will be described. Reference numeral 1 indicates a top plate on a learning desk, and reference numeral 2 indicates an upper shelf device. The upper shelf device 2 which can be detachably mounted on the top plate 1 includes a pair of left and right side plates 3 and 3, a back plate 4 standing upright between rear end edges of the left and right side plates 3 and 3, and left and right side plates 3 and 3. The upper shelf plate 5 and the lower shelf plate 8 are horizontally attached between the inner surfaces of the three. A lighting fixture 6 which is long in the left-right direction is attached to the lower shelf front part of the upper shelf plate 5 so as to be movable back and forth. Reference numeral 7 is a shade made of a light-transmissive material provided on the front end side of the lighting fixture 6.

As can be understood from FIG. 1, the lower shelf plate 8 in this embodiment has a central portion 8a that covers the upper surfaces of the pair of left and right small drawers 9 and 9 at a high position in the left and right central portions, and the left and right side portions thereof. Set 8b and 8b to a low position. Reference numerals 10 and 10 denote intermediate partition plates that partition the central portion 8a and the left and right side portions 8b and 8b. Further, as can be understood from FIG. 2, the lower shelf 8 has a plan view shape such that a depth dimension is short and rectangular so that the lower shelf front edge 11 approaches the rear of the top 1 in the central portion 8a. The front edges 12 and 12 of the left and right side portions 8b 1 and 8b are substantially connected to the front edge 11 of the central portion 8a and approach the front edges of the left and right side portions 3 and 3, respectively. It is formed in an inclined shape so as to be located in front of the top plate 1. In other words, the inner surface of the side plates 3 and 3 is formed in an inclined shape such that the depth dimension L1 is large and the depth dimension L2 becomes shorter toward the central portion.

Reference numeral 13 is a partition plate in the upper shelf plate 5, reference numeral 14 is a partition plate in the lower shelf plate 8, and reference numerals 15 and 16 are holes of a power cord formed in the back plate 4 to the lighting fixture 6. It is for the power cord and the power cord to the outlet 17 on the front of the left side 8b of the lower shelf. In addition, the front edges of the left and right side plates 3 and 3 have a depth dimension capable of sufficiently supporting the side surfaces of the respective shelves at the upper shelves 5 and the lower shelves 8 as shown in FIG. 3 in a side view. Then, the front portions of the side plates 3 and 3 in the middle of the upper and lower sides are cut out in a convex shape rearward so that the side plates 3 are formed in a U-shape in a side view, and the decoration columns 18 are attached. Further, in the embodiment, the upper shelf device 2 is configured to be clamped and fixed to the top plate 1 via the clamps 19 and 19 in the mounting holes formed in the left and right side plates 3 and 3.

With this configuration, the left and right side portions 8b, 8b of the lower shelf plate 8 of the upper shelf device 2 placed on the rear side of the top plate 3 of the desk are trapezoidal in plan view, and have a depth near the inner surface of the side plate 3. Since the size is large and the depth dimension becomes shorter as it approaches the central portion 8a of the lower shelf plate 8, if a large-sized book is leaned to the side plate 3 side, and a small-sized book is leaned to the left and right central portions of the lower shelf plate 8. Well, both large and small books can be placed. Moreover, since the front edge of the left-right central portion 8a of the lower shelf 8 is retracted toward the rear of the top plate 1 of the desk, the top plate 1 can be widely used.

The upper shelf device 2 of the present invention may be an integral one in which a side plate or the like is fixed to the top plate 3 of the desk. Further, the back plate 4 may be omitted. Further, the lower shelf plate 8 may be formed such that the central portion 8a and the left and right side portions 8b, 8b have the same height.

[0012]

[Operation and effect of the device]

 As described above, according to the present invention, the lower shelf plate 8 of the upper shelf device 2 placed on the rear side of the upper surface of the top plate 3 of the desk has a trapezoidal plan view on both left and right sides 8b and 8b. Since the depth dimension is large near the inner surface of the side plate 3 and becomes smaller as it approaches the central portion 8a of the lower shelf plate 8, a large-sized book is leaned toward the side plate 3 and a small-sized book is placed on the lower shelf plate. It suffices to lean the right and left central portion 8a or the left and right side portions 8b, 8b close to the central portion 8a, and both large and small books can be placed. Moreover, since the front edges of the left and right central portions of the lower shelf 8 are retracted toward the rear of the top plate 1 of the desk, the top plate 1 can be widely used. In other words, due to the shape of the lower shelf plate in the upper shelf device 2, the top plate of the desk can be widely used, but any large or small book can be placed, and a convenient desk can be provided. Of.
