　この従来の棚付き机では、第１使用形態から第２使用形態又は第３使用状態への変更に伴って取外された上側棚を、そのまま机本体の膝入れ空間の奥側に横架姿勢で支持させることにより、該上側棚を収納棚として再利用することができるから、使用形態の変更に伴って机上から取外される上側棚を廃棄する必要がなく、資源の無駄使いを抑制することができる利点がある。 In this conventional desk with shelves, the upper shelf removed along with the change from the first use mode to the second use mode or the third use state is directly laid on the back side of the lap space of the desk body. By supporting the upper shelf, the upper shelf can be reused as a storage shelf, so that there is no need to dispose of the upper shelf that is removed from the desk in accordance with a change in the use form, thereby suppressing waste of resources. There are advantages that can be.

　しかしながら、上側棚をそのまま机本体の膝入れ空間内に架設するため、上側棚の左右最大長さを、膝入れ空間を形成する机本体の両側板の左右方向での相対向面間隔よりも少し小さく構成しなければならず、しかも、それと同じ寸法分だけ、下側棚の左右最大長さも、机本体の両側板の左右方向での相対向面間隔よりも小に構成する必要があり、その結果、机本体と下側棚及び上側棚との形態上の大きな制約になるとともに、上側棚の再利用の形態が、机本体の膝入れ空間内での収納棚に用いる一形態だけであるため、使用者側の選択の余地がなかった。 However, since the upper shelf is directly installed in the kneeling space of the desk main body, the maximum left and right length of the upper shelf is set to be slightly smaller than the distance between the opposing surfaces in the left and right direction of both side plates of the desk main body forming the kneeling space. It must be configured to be small, and the maximum length of the left and right sides of the lower shelf must be smaller than the distance between the opposing surfaces in the left and right direction of both side plates of the desk body by the same dimension. As a result, the form of the desk body, the lower shelf, and the upper shelf is greatly restricted, and the form of reuse of the upper shelf is only one form used for the storage shelf in the lap space of the desk body. , There was no choice for the user.

　また、上述のような従来の不都合を解消する方法として、本願発明者は、図１４〜図１６に示すような棚付き机を開発した。この棚付き机の上側棚Ｃを、左右一対の棚側板２０と、該両棚側板２０を固定連結する背面板２１、及び、前記両棚側板２０間に亘って脱着自在に固定連結される単独で載置使用可能な単一の本立て５０とから構成するとともに、前記本立て５０の左右最大長さＷ５を、机本体Ａの膝入れ空間Ｓの奥側に入り込み配置可能な寸法に構成した。 As a method for solving the above-mentioned conventional inconveniences, the present inventor has developed a desk with shelves as shown in FIGS. The upper shelf C of the desk with shelves is composed of a pair of left and right shelf side plates 20, a back plate 21 for fixedly connecting the two shelf side plates 20, and a single detachably fixedly connected between the two shelf side plates 20. And a single main stand 50 that can be placed and used, and the maximum left and right length W5 of the main stand 50 is configured to be able to enter the back side of the knee space S of the desk main body A and be arranged.

　前記本立て５０は、左右一対の外側板５０Ａと、両外側板５０Ａの後端部に亘って固定連結される背面板５０Ｂと、両外側板５０Ａの前端部に亘って固定連結される前脚としての前面板５０Ｃ、及び、これらに三者５０Ａ，５０Ｂ，５０Ｃに亘って水平姿勢で固定連結される載置板５０Ｄとから構成されていて、机本体Ａの天板１上面等に単独で載置使用可能に構成されている。 The book stand 50 includes a pair of left and right outer plates 50A, a rear plate 50B fixedly connected to the rear ends of both outer plates 50A, and front legs as fixed legs connected to the front ends of the both outer plates 50A. It comprises a front plate 50C and a mounting plate 50D fixedly connected to the three members 50A, 50B, 50C in a horizontal posture, and is independently mounted on the top surface of the top plate 1 of the desk body A or the like. It is configured to be usable.

　また、前記机本体Ａのうち、膝入れ空間Ｓを挟んで左右方向で相対向する側板２の各板厚ｔ１と、上側棚Ｃの両棚側板２０の各板厚ｔ２とを同一又はほぼ同一寸法に構成するとともに、前記机本体Ａの両側板２の左右方向での外面間隔Ｗ１と、上側棚Ｃの両棚側板２０の左右方向での外面間隔Ｗ２とを同一又はほぼ同一寸法に構成し、更に、前記机本体Ａの両側板２の左右方向での相対向面間隔Ｗ３と、上側棚Ｃの両棚側板２０の左右方向での相対向面間隔Ｗ４とを、前記本立ての左右最大長さＷ５よりも少し大となる同一又はほぼ同一寸法に構成して、前記上側棚Ｃから分解された本立て５０を、机本体Ａの両側板２間に入り込み配置自在に構成してある。 Further, in the desk main body A, the plate thickness t1 of the side plate 2 facing each other in the left-right direction across the knee space S and the plate thickness t2 of both the shelf side plates 20 of the upper shelf C are the same or substantially the same. The width W1 of the both side plates 2 of the desk main body A in the left-right direction and the width W2 of the outer surfaces of the two side plates 20 of the upper shelf C in the left-right direction are the same or substantially the same. Further, the distance W3 between the opposing surfaces in the left-right direction of the side plates 2 of the desk body A and the distance W4 between the opposing surfaces in the left-right direction of the two side plates 20 of the upper shelf C are determined by the maximum left-right length of the bookstand. The bookshelf 50, which is configured to have the same or substantially the same size slightly larger than the height W5, is disassembled from the upper shelf C, and is configured to be freely disposed by being inserted between both side plates 2 of the desk body A.

　前記本立て５０の各外側板５０Ａには、上側棚Ｃの棚側板２０に埋設されたナット部材及び机本体Ａの側板２に埋設されたナット部材５１に螺合固定するボルト５２に対する取付孔が貫通形成されているとともに、前記机本体Ａの両側板２と背面板３とに亘って、膝入れ空間Ｓの奥側位置において本立て５０を載置支持する棚板５３が取付けられている。
　尚、前記上側棚Ｃとしては、少なくとも左右一対の棚側板２０と単独で載置使用可能な単一の本立て５０とを備えていればよい。 A mounting hole for a bolt 52 screwed and fixed to a nut member embedded in the shelf side plate 20 of the upper shelf C and a nut member 51 embedded in the side plate 2 of the desk body A penetrates through each outer plate 50A of the main stand 50. A shelf plate 53 for mounting and supporting the bookstand 50 at the back of the knee space S is attached to both sides 2 and the back plate 3 of the desk body A.
Note that the upper shelf C only needs to include at least a pair of left and right shelf side plates 20 and a single book stand 50 that can be placed and used independently.

　また、前記下側棚Ｂの構成は、後述する第１実施形態の下側棚Ｂと実質的に同一で、同じ構成部材には同一記号を付記してそれの説明は省略する。 The structure of the lower shelf B is substantially the same as that of the lower shelf B of the first embodiment described later, and the same components are denoted by the same reference numerals and description thereof is omitted.

　この棚付き机による場合は、上側棚Ｃの両棚側板２０の左右方向での相対向面間隔Ｗ２と机本体Ａの両側板２の左右方向での外面間隔Ｗ１とを同一又はほぼ同一寸法に統一構成しながらも、第１使用形態から第２使用形態又は第３使用状態への変更に伴って取外された上側棚Ｃのうち、両棚側板２０間から分離された本立て５０を机本体Ａの膝入れ空間Ｓの奥側に支持させることができるばかりでなく、この本立て５０を机本体Ａの天板１上面に単独で載置して使用することもできる。 In the case of this desk with shelves, the distance W2 between the opposing surfaces in the left-right direction of both side plates 20 of the upper shelf C and the distance W1 between the outer surfaces in the left-right direction of both side plates 2 of the desk body A are the same or almost the same. While having the unified configuration, the bookstand 50 separated from the space between the both shelf side plates 20 in the upper shelf C removed in accordance with the change from the first use mode to the second use mode or the third use state is used as a desk body. In addition to being able to be supported on the back side of the knee space S of A, the book stand 50 can also be used alone by being placed on the upper surface of the top plate 1 of the desk body A.

　従って、従来のような机本体と下側棚及び上側棚との形態上の大きな制約を解消して、机本体と下側棚及び上側棚との設計の自由度を高めることができるようにしながらも、第１使用形態から第２使用形態又は第３状態への変更に伴って取外された上側棚を再利用する際、机本体の膝入れ空間内での収納棚に用いる形態と、机本体の天板上面等に載置使用する形態とに選択することができる。 Therefore, it is possible to eliminate the great limitation on the configuration of the desk body and the lower shelf and the upper shelf as in the related art, and to increase the degree of freedom in designing the desk body and the lower shelf and the upper shelf. Also, when reusing the upper shelf removed in accordance with the change from the first usage mode to the second usage mode or the third state, the upper shelf is used as a storage shelf in the lap space of the desk body, It can be selected to be mounted on the top plate or the like of the main body.

　本発明は、上述の開発された棚付き机に更に改良を加え、机本体と下側棚及び上側棚との設計の自由度を高めることができるようにしながらも、第１使用形態から第２使用形態又は第３使用状態への変更に伴って取外された上側棚の再利用形態の選択肢を拡大することができるようにする点にある。 The present invention further improves the above-developed desk with shelves, so that the degree of freedom in designing the desk body, the lower shelf, and the upper shelf can be increased, while the second mode is changed from the first mode of use. The present invention is intended to allow the user to expand the options of the reusable form of the upper shelf removed with the change to the use form or the third use state.
