【発明の属する技術分野】
本発明は、物品を載置する載置面を備えた棚構造に関する。
【0002】
【従来の技術】
従来、書籍を陳列する際には、本棚が用いられていた。
【0003】
この本棚の棚受けには、棚板が架橋されており、この棚板上に書籍を載置できるように構成されている。
【0004】
【発明が解決しようとする課題】
しかしながら、陳列される書籍には、複数のサイズがあり、各サイズでの書籍の奥行き寸法が異なる。
【0005】
このため、奥行きが大きなサイズの書籍に合わせて作られた本棚に、小さなサイズの書籍を陳列した場合、本棚の手前から書籍までの距離が遠くなる一方、奥行きが小さなサイズの書籍に合わせて作られた本棚に、大きなサイズの書籍を陳列する場合、書籍が本棚の手前に飛び出してしまうという問題があった。
【0006】
本発明は、このような従来の課題に鑑みてなされたものであり、奥行きを変更することができる棚構造を提供することを目的とするものである。
【0007】
【課題を解決するための手段】
前記課題を解決するために本発明の請求項1の棚構造にあっては、物品が載置される載置面を、棚受けの手前側に配設される棚板と、該棚板の奥側に配設される延長部材とで構成し、前記延長部材の奥行き方向の一縁を手前側に配置した第1状態と奥側に配置した第2状態との両状態で当該延長部材を支持する支持領域を前記棚受けに設定する一方、前記延長部材に載置領域の奥行きを定める壁部を立設し、該壁部を、前記延長部材の奥行き方向中心からずらした位置に設けた。
【0008】
すなわち、延長部材に起立した壁部は、当該延長部材の奥行き方向中心からずれた位置に設けられており、この延長部材を支持する棚受けには、前記延長部材の奥行き方向の一縁を、手前側に配置した第1状態と奥側に配置した第2状態との両状態で支持可能な支持領域が設定されている。
【0009】
このため、前記延長部材の向きを変えることによって、棚板の手前側の縁から前記延長部材の前記壁部までの奥行きが変更される。
【0010】
また、請求項2の棚構造においては、前記壁部を、前記延長部材の前記一縁に設けた。
【0011】
これにより、延長部材の向きを変えた際の奥行きの変化量が、前記延長部材の奥行き寸法となる。
【0012】
さらに、請求項3の棚構造では、前記延長部材の底面中央部に下方開口状の係止用挿入部を設定するとともに、前記棚板の底面に下方開口状の位置決め用挿入部を設定する一方、前記棚受けに、前記延長部材の前記係止用挿入部へ挿入した状態で当該延長部材に係合する前記手前側に延出した鉤状の係止部と、前記棚板の前記位置決め用挿入部に挿入した状態で当該棚板を位置決めする位置決め部とを設けた。
【0013】
すなわち、延長部材の係止用挿入部へ棚受けの係止部を挿通した後、延長部材を奥側へスライドすることによって、前記係止部が前記延長部材に係合し、当該延長部材が取り付けられる。
【0014】
そして、棚板の位置決め用挿入部へ棚受けの位置決め部を挿入することで、当該棚板の手前側へのズレが防止される。
【0015】

【0019】
前記支持面22の端縁には、図1にも示したように、長方形状の位置決め部41が上方へ向けて折曲形成されており、該位置決め部41より本棚1の奥側Bの部位には、係止部42が折曲形成されている。この係止部42は、上方へ向けて折曲された起立部43と、該起立部43より前記位置決め部41側に延出した延出部44とからなり、鉤状に形成されている。
【0020】
前記側壁部11の相対向する部位に取り付けられた前記棚受け14,14間には、棚受け14の手前側Fに配置される棚板51と、該棚板51の奥側Bに配置される延長部材52とが架橋されており、両部材51,52によって物品としての本を載置する載置面が形成されている。
【0021】
前記棚板51は、金属板によって形成されており、奥行き方向の両縁部には、下方へ折曲された下方折曲部61,61が形成されている。該下方折曲部61,61の先端部は、内方へ折曲されており、前記棚受け14に支持される支持面62,62が形成されている。該支持面62の先端部は、上方へ折曲されており、上方折曲部63が形成されている。この棚板51の両縁部に形成された上方折曲部63,63間の離間寸法は、前記位置決め部41を挿入できる寸法に設定されており、前記棚板51の底面には、前記位置決め部41を挿入可能な下方開口状の位置決め用挿入部64が、前記両上方折曲部63,63間に形成されている。
【0022】
これにより、前記棚板51は、前記位置決め用挿入部64に位置決め部41が挿入された状態で、前記両上方折曲部63,63が前記位置決め部41に当接して移動規制されることにより、位置決めされるように構成されている。
【0023】
前記延長部材52も、図2にも示したように、金属板によって形成されており、奥行き方向の一方の縁部には、下方へ折曲された下方折曲部71が形成されている。該下方折曲部71の下端部は、内方へ折曲されており、前記棚受け14に支持される支持面72が形成されている。また、前記延長部材52における奥行き方向の他方の縁部は、上方へ折曲された後、下方へ折り返されてなる壁部73が形成されており、当該延長部材52の奥行き方向の他方の縁部、すなわち奥行き方向中心より他方側へずらした位置には、載置領域の奥行きを定める前記壁部73が立設されている。
【0024】
この壁部73より下方に延出した延出部81の下端部は、内方へ折曲され、前記棚受け14に支持される支持面が82形成されており、当該延長部材52の奥行き方向の両縁部には、前記棚受け14に支持される支持面72,82が形成されている。両支持面72,82間の離間寸法は、前記係止部42を挿入できる寸法に設定されており、前記延長部材52の底面中央部には、前記係止部42を挿入可能な下方開口状の係止用挿入部83が、前記両支持面72,82間に形成されている。
【0025】
これにより、図3にも示したように、前記延長部材52の前記一方の縁部を手前側Fに配置した第1状態91と、奥側Bに配置した第2状態92とを任意に形成できるように構成されており、前記棚受け52には、図1に示したように、前記棚板51を支持する棚板支持領域93の奥側Bに、前記延長部材52を前記両状態91,92にて支持可能な支持領域94が設定されている。
【0026】
そして、前記第1状態91において、前記延長部材52の上面101が前記棚板51の上面102の延長上に配置され、両上面101,102で面一な載置面を形成するように構成されており、前記棚板51の手前側Fの縁から前記延長部材52の前記壁部73までの奥行き寸法D1が、A4サイズの書籍に適合した210mmとなるように設定されている。また、前記第2状態92では、前記延長部材52の上面101と前記棚板51の上面102とが前記壁部73で区画されるように構成されており、前記棚板51の手前側Fの縁から前記延長部材52の前記壁部73までの奥行き寸法D2が、B5サイズの書籍に適合した180mmとなるように設定されている。
【0027】
そして、前記各状態91,92において、前記係止用挿入部83に挿入された前記係止部42の延出部44が、いずれかの支持面72,82上に位置した状態で、前記係止部42が延長部材52と係合するように構成されている。
【0028】
以上の構成にかかる本実施の形態において、この本棚1の下段にA4サイズの書籍を載置して陳列する棚を形成する際には、先ず、起立した壁部73が本棚1の手前側Fとなるように延長部材52をセットし、棚受け14の係止部42を延長部材52の係止用挿入部83へ挿入する。この状態で、前記延長部材52を本棚1の奥側Bへスライドさせ、係止部42の延出部44を延長部材52の支持面72に係止して延長部材52を棚受け14に固定し、当該延長部材52の抜けが防止された第1状態91を形成する。
【0029】
そして、棚受け14の位置決め部41を棚板51の位置決め用挿入部64へ挿入し、当該棚板51の奥行き方向への移動を規制する。すると、前記棚板51の手前側Fの縁から前記延長部材52の前記壁部73までの奥行き寸法D1がA4サイズの書籍に適合した210mmとなり、A4サイズの書籍を載置可能な載置面を、前記棚板51の上面102と前記延長部材52の上面101とによって形成することができる。
【0030】
このとき、前記延長部材52の手前側Fへの移動を、前記棚板51によって阻止することができる。よって、前記延長部材52の不用意な外れを防止することができる。
【0031】
また、この上段にB5サイズの書籍を載置して陳列する棚を形成する際には、前記壁部73が本棚1の手前側Fとなるように延長部材52をセットし、棚受け14の係止部42を延長部材52の係止用挿入部83へ挿入する。この状態で、前記延長部材52を本棚1の奥側Bへスライドさせ、係止部42の延出部44を延長部材52の支持面82に係止して延長部材52を棚受け14に固定し、当該延長部材52の抜けが防止された第2状態92を形成する。
【0032】
そして、棚受け14の位置決め部41を棚板51の位置決め用挿入部64へ挿入し、当該棚板51の奥行き方向への移動を規制する。すると、前記棚板51の手前側Fの縁から前記延長部材52の前記壁部73までの奥行き寸法D2が、B5サイズの書籍に適合した180mmとなり、B5サイズの書籍を載置可能な載置面を、前記棚板51の上面102によって形成することができる。
【0033】
このとき、前記延長部材52の手前側Fへの移動を、前記棚板51によって阻止することができる。よって、前記延長部材52の不用意な外れを防止することができる。
【0034】
このように、棚受け14に取り付けられる延長部材52の向きを変えるだけで、棚板51の手前側Fの縁から延長部材52の壁部73までの奥行きを変更することができ、載置される書籍のサイズに合わせた奥行きの棚を形成することができる。したがって、奥行きがA4サイズの書籍に合わせて作られた本棚に、B5サイズの書籍を陳列し、本棚の手前から書籍までの距離が遠くなり、書籍の取り出しが困難になったり、奥行きがB5サイズの書籍に合わせて作られた本棚に、A4サイズの書籍を陳列し、書籍が本棚の手前に飛び出してしまうといった不具合を解消することができる。
【0035】
そして、奥行きを定める前記壁部73は、前記延長部材52の一縁に設けられているので、前記壁部73が延長部材52の奥行き方向中央部寄りに設定された場合と比較して、延長部材52の向きを変えた際の奥行きの変化量を大きくすることができる。よって、前記延長部材52で形成される載置面を有効に利用することができる。
【0036】
【発明の効果】
以上説明したように本発明の請求項1の棚構造にあっては、棚板の奥側に配設され該棚板と共に載置面を形成する延長部材の向きを変えて配置するだけで、棚板の手前側の縁から前記延長部材に立設された壁部までの奥行きを変更することができる。
【0037】
このように、載置される物品に合わせて奥行きを変更することができるため、小さな物品を奥行きの大きな棚に載置し物品の取り出しが困難になたり、大きな物品を奥行きの小さな棚に載置して物品が手前に飛び出してしまうといった不具合を解消することができる。
【0038】
また、請求項2の棚構造においては、延長部材の向きを変えた際の奥行きの変化量を、前記延長部材の奥行き寸法とすることができる。
【0039】
このため、壁部が延長部材の中央部寄りに設定された場合と比較して、奥行き変更時の変化量を大きくすることができる。
【0040】
さらに、請求項3の棚構造では、延長部材の位置決め用挿入部へ棚受けの係止部を挿通した後、延長部材を奥側へスライドすることによって、前記係止部を延長部材に係合した状態で、該延長部材を固定することができる。また、棚板の位置決め用挿入部へ棚受けの位置決め部を挿入することによって、当該棚板の手前側のズレを防止することができる。
【0041】
これにより、前記延長部材の手前側へのズレを前記棚板で規制することができるので、前記延長部材の不用意な外れを防止することができる。

Then, the depth dimension D1 from the edge of the front side F of the shelf board 51 to the wall portion 73 of the extension member 52 becomes 210 mm suitable for an A4 size book, and a mounting surface on which an A4 size book can be mounted. Can be formed by the upper surface 102 of the shelf 51 and the upper surface 101 of the extension member 52.
[0030]
At this time, the movement of the extension member 52 to the front side F can be prevented by the shelf board 51. Therefore, the careless detachment of the extension member 52 can be prevented.
[0031]
When forming a shelf on which B5 size books are placed and displayed on the upper stage, the extension member 52 is set so that the wall 73 is located on the front side F of the bookshelf 1, and The locking portion 42 is inserted into the locking insertion portion 83 of the extension member 52. In this state, the extension member 52 is slid to the back side B of the bookshelf 1 and the extension portion 44 of the locking portion 42 is locked to the support surface 82 of the extension member 52 to fix the extension member 52 to the shelf receiver 14. Then, the second state 92 in which the extension member 52 is prevented from coming off is formed.
[0032]
Then, the positioning part 41 of the shelf receiver 14 is inserted into the positioning insertion part 64 of the shelf 51 to restrict the movement of the shelf 51 in the depth direction. Then, the depth dimension D2 from the edge of the front side F of the shelf board 51 to the wall portion 73 of the extension member 52 becomes 180 mm, which is suitable for a B5 size book, and the placement on which the B5 size book can be placed A surface can be formed by the upper surface 102 of the shelf 51.
[0033]
At this time, the movement of the extension member 52 to the front side F can be prevented by the shelf board 51. Therefore, the careless detachment of the extension member 52 can be prevented.
[0034]
In this way, the depth from the edge of the front side F of the shelf board 51 to the wall 73 of the extension member 52 can be changed only by changing the direction of the extension member 52 attached to the shelf receiver 14 and placed. The depth of the shelf can be formed according to the size of the book. Therefore, a B5 size book is displayed on a bookshelf made to fit an A4 size book, and the distance from the front of the bookshelf to the book becomes longer, making it difficult to take out the book or making the B5 size book. An A4 size book is displayed on a bookshelf made in accordance with the book, and the problem that the book jumps out of the bookshelf can be solved.
[0035]
Since the wall portion 73 that determines the depth is provided at one edge of the extension member 52, the wall portion 73 is extended compared to the case where the wall portion 73 is set closer to the center in the depth direction of the extension member 52. The amount of change in the depth when the direction of the member 52 is changed can be increased. Therefore, the mounting surface formed by the extension member 52 can be effectively used.
[0036]
【The invention's effect】
As described above, in the shelf structure according to claim 1 of the present invention, it is only necessary to change the direction of the extension member that is disposed on the back side of the shelf plate and forms a mounting surface together with the shelf plate, and The depth from the front edge of the shelf to the wall standing on the extension member can be changed.
[0037]
In this way, the depth can be changed according to the article to be placed, so that it is difficult to remove a small article on a shelf with a large depth and remove the article, or place a large article on a shelf with a small depth. It is possible to solve the problem that the article is placed and the article jumps out toward the user.
[0038]
Further, in the shelf structure according to the second aspect, the amount of change in the depth when the direction of the extension member is changed can be used as the depth dimension of the extension member.
[0039]
For this reason, compared with the case where the wall is set near the center of the extension member, the amount of change at the time of changing the depth can be increased.
[0040]
Further, in the shelf structure according to the third aspect, after the locking portion of the shelf receiver is inserted into the positioning insertion portion of the extension member, the extension member is slid to the rear side so that the locking portion is engaged with the extension member. In this state, the extension member can be fixed. In addition, by inserting the positioning portion of the shelf receiver into the positioning insertion portion of the shelf, it is possible to prevent the front side of the shelf from shifting.
[0041]
Accordingly, the shift of the extension member toward the front side can be regulated by the shelf plate, so that careless detachment of the extension member can be prevented.
