Description

  The present invention relates to a system desk including a desk and a bookcase that can store books and the like.

  Conventionally, as an example of a set of a desk and a bookcase, a learning desk with a bookcase composed of a learning desk and a bookcase placed on the top plate of the learning desk is known (for example, Patent Literature 1). In such a learning desk, it is generally difficult to form a large bookcase due to its structure, and the bookcase has a relatively small volume. For this reason, for example, this configuration can be adequately accommodated when the number of books that should be stored by the user in the lower grades of elementary school is relatively small. However, if the number of books to be stored increases as the user grows, the storage volume There is a problem that tends to be short.

  To solve this problem, for example, as shown in Patent Document 2, there is known a system desk provided with a desk and a self-supporting bookcase with a sufficient storage capacity. This self-supporting bookcase (bookcase) is composed of an upper bookcase and a lower bookcase, so that the upper bookcase can be placed on the top of the desk according to the user's preference, or the upper bookcase can be placed on the lower bookcase. Can be placed. Further, in Patent Document 2, a book shelf (an upper book shelf and a lower book shelf) is formed in accordance with the left and right width dimensions of the desk and the book shelf is placed on the back side of the desk (see FIG. 1), or the side of the desk. (See FIG. 4).

A desk provided with a side top plate (for example, the top plate 16 in the embodiment), a pair of side plates extending vertically and opposed to each other with a predetermined interval, and a shelf board supported substantially horizontally between the pair of side plates. And a storage shelf (for example, the wide book shelf 30 and the narrow book shelf 50 in the embodiment) that is used in parallel with the desk. The plurality of storage shelves have a total interval value that is the sum of the predetermined intervals in each of the plurality of storage shelves. Neighborhood One of the plurality of storage shelves is formed such that the predetermined interval substantially matches the short side length of the desk-side top plate, and the plurality of storage shelves Are arranged side by side on the long side of the desk side top plate, and the plurality of storage shelves are arranged in the long side direction along the long side with the side plates adjacent to each other, and the long side direction The side plate at the one side end of the desk side top plate is aligned with the one side end portion in the long side direction of the desk side top plate, and the side plate at the other side end portion in the long side direction is aligned with the long side of the desk side top plate Can be juxtaposed along the other side end in the direction, and when any one of the storage shelves is juxtaposed to the side of the short side of the desk side top plate, While positioning the side plates of the storage shelf to be substantially parallel, The side plate on one side in the short side direction along the side is aligned with the one side end portion in the short side direction of the desk side top plate, and the side plate on the other side in the short side direction is aligned with the desk side top plate. It is possible to align the other side end in the short side direction.

  In the system desk, the storage shelf is supported by the pair of lower side plates (for example, the side plate 41 and the side plate 61 in the embodiment) opposed to each other with the predetermined interval, and the plane supported substantially horizontally by the lower side plate. A lower storage shelf (for example, the wide lower shelf 30L and the narrow lower shelf 50L in the embodiment) provided with a rectangular shelf-side top plate (for example, the top plate 45 and the top plate 65 in the embodiment), and the predetermined interval And a pair of upper side plates opposed to each other (for example, the side plate 31 and the side plate 51 in the embodiment), and the shelf plate supported substantially horizontally between the pair of upper side plates, The upper storage shelf (for example, the wide upper shelf 30U and the narrow upper shelf 50U in the embodiment) that can be placed on the upper side is configured, and the shelf-side top plate has at least one pair of opposing side lengths having the predetermined interval. And almost one While being formed so as to, it is preferable that the said lower plate is supported at a height substantially the same as the desk-side top plate.

  The system desk according to the present invention is formed such that a total interval value obtained by summing a predetermined interval between the side plates in each of the plurality of storage shelves substantially coincides with the long side length of the desk side top plate. One of them is formed such that the predetermined interval substantially coincides with the short side length of the desk-side top plate. Therefore, the storage shelves can be neatly arranged to match the dimensions of the desk both when the storage shelves are placed beside the desk and when the storage shelves are placed behind the desk.

Then, the direction of the narrow lower shelf 50 </ b> L is made from the left side so that books and the like can be taken in and out, and is brought to the desk 10, and the storage wagon 20 is brought to the left below the desk 10. By doing so, books and the like can be taken in and out of the narrow lower shelf 50L while sitting on a chair, and usability is improved.

  With reference to FIG. 14, a system desk 8 as a seventh modification will be described.

  The system desk 8 has an arrangement configuration in which a wide book shelf 30 and a narrow book shelf 50 are arranged on the left side of the desk 10. Such an arrangement is effective particularly for a room having a relatively large space in the left-right direction. In the case of this arrangement configuration, it is possible to grasp at a glance what kind of books are stored in the wide book shelf 30 and the narrow book shelf 50.

  In the above, the modification (system desk 2-8) which changed only the arrangement configuration using the same component as the system desk 1 was demonstrated. By the way, the top plate 16 of the desk 10 can be formed in various sizes, and the left and right widths and the front and rear widths may be formed larger than the top plate 16 in some cases. It is possible to maintain the above dimensional relationship by widening the left and right widths of the wide book shelf 30 and the narrow book shelf 50 with respect to the expansion of the top plate, but in such a case, the wide book shelf 30 and the narrow book shelf 50 are maintained. The strength of the steel tends to decrease. An example of a configuration that is particularly effective in such a case is a system desk 100 shown in FIGS. 15A and 15B, and the system desk 100 will be described below. In FIGS. 15A and 15B, the same components as those of the system desk 1 are denoted by the same reference numerals.

  As shown in FIG. 15A, the system desk 100 is provided with a desk 10 ′ having a top plate 16 ′ formed in a size of a front-rear width D4 (> D1) with a left-right width W4 (> W1). For example, two wide bookcases 30 and one narrow bookcase 50 are combined. Here, the dimension obtained by adding the left and right width W3 of the narrow book shelf 50 to twice the left and right width W2 of the wide book shelf 30 is coincident with the left and right width W4 of the desk 10 ′. Further, the dimension obtained by adding the left and right width W3 of the narrow book shelf 50 to the left and right width W2 of the wide book shelf 30 coincides with the front and rear width D4 of the desk 10 ′.

  In the configuration of the system desk 100, for example, when it is desired to make the arrangement configuration as compact as possible in the left-right direction, as shown in FIG. 15A, two wide bookcases 30 and one narrow width are provided behind the desk 10 '. It is preferable to arrange the bookshelf 50 side by side. By doing so, while ensuring the strength of each of the wide book shelf 30 and the narrow book shelf 50, the left and right widths of the top plate 16 'can be made to coincide with each other, thereby providing a clean arrangement as a whole.

  For example, when the space in the front-rear direction is limited, as shown in FIG. 15 (b), one wide book shelf 30 is separated into a wide lower shelf 30L and a wide upper shelf 30U, and the width is narrow. The book shelf 50 is separated into a narrow lower shelf 50L and a narrow upper shelf 50U. The separated wide upper shelf 30 </ b> U and narrow upper shelf 50 </ b> U are placed on the top plate 16 ′, and are connected and fixed to the top plate 16 ′ using the connecting metal fitting 70. On the other hand, the separated wide lower shelf 30L and narrow lower shelf 50L are arranged side by side on the left side of the top plate 16 'so as to be accessible from the right side. Then, the wide book shelf 30 in which the wide lower shelf 30L and the wide upper shelf 30U are integrated is positioned on the right side of the top plate 16 '. With this arrangement, the wide lower shelf 30L and the narrow lower shelf 50L do not jump out in the front-rear direction with respect to the top plate 16 'while ensuring the strength of each of the wide book shelf 30 and the narrow book shelf 50. Can be arranged.
