Description

【0001】
【発明の属する技術分野】
本発明は、支柱と連結杆とを連結する装置に関し、例えば、軽量または中重量の商品を陳列する陳列棚の支柱と連結杆との連結に好適な装置に関する。
【0002】
【従来の技術】
従来、図5に示すように、陳列棚、本棚、及び物品保管棚等の棚類における陳列棚(20)の支柱(21)と連結杆(22)(23)は、ボルト(24)とナット(25)からなる連結装置によって連結されている。
【0003】
【発明が解決しようとする課題】
しかし、上記の連結装置は、支柱(21)と連結杆(22)(23)とを組立るとき、ボルト(24)とナット(25)とを互い螺合するため、支柱(21)と連結杆(22)(23)との組立に手間を要するという問題がある。
また、分解する時、ボルトとナットを回転させて外すため、分解に手間を要するという問題がある。
さらに、外したボルトとナットを紛失しないように保管しなければならないという問題もある。
【0004】
なお、連結装置は、棚類の支柱と連結杆の他に、プレハブ式の簡易物置、家屋等における支柱と連結杆とを連結固定する場合もある。この場合においても、上記と同様な問題を有している。
【0005】
本発明は、上記の問題点に鑑み、支柱と連結杆との組立を容易に行なえ、かつ互いに位置がずれにくい連結装置を提供することを目的としている。
【0006】
【課題を解決するための手段】
本発明によると、上記課題は、左右1対の支柱の上部の対向面に、支柱の上端に開口する前後1対の係止孔を設けることにより、両係止孔間に弾性片を形成し、前記両係止孔に、左右方向を向く連結杆の両端に設けた前後1対の係止爪を係止して、前記支柱と前記連結杆とを連結するとともに、前記弾性片と、それに対向するように、前記連結杆の端部における両係止爪間に設けた弾性舌片との一方に突設した突部を、他方に形成した受入部に嵌合して、前記支柱と前記連結杆とが互いに外れないようにすることにより解決される。
【0007】
【発明の実施の形態】
以下、本発明の実施の形態を、図1〜図4に基づいて説明する。
この例では、連結固定装置は、図1に示す、商品の陳列棚(1)の支柱(2)と連結杆(3)(4)とを連結する装置としてある(棚板は省略してある)。
左右1対の支柱(2)は、角筒状をなし、その下端には、前後方向を向く角筒状の脚(5)が設けられている。脚(5)の前後端には、キャップ(6)が装着されている。
【0008】
図3及び図4に示すように、1対の支柱(2)の対向面(2a)の上部と下部には、前後1対の縦長のスリット状の係止孔(7)(8)が形成されている。
図3に示すように、支柱(2)の最上部に形成された前後1対の係止孔(7)は、支柱の上端に開口する溝になっている。このため、支柱(2)の上端には、前後1対の係止孔(7)によって、それらの間に左右方向に弾性撓曲しうる弾性片(9)が形成されている。
【0009】
図4に示すように、支柱(2)の下部には、前後1対の係止孔(8)が、上下2段として、したがって合計4個形成されている。
【0010】
支柱(2)の上部に設けた1対の係止孔(7)の間、すなわち弾性片(9)のほぼ中央と、支柱(2)の下部に設けた下位の1対の係止孔(8)の間とには、後述する突部(10)が嵌合する受入部である貫通孔(11)が設けられている。
なお、受入部には、貫通孔(11)の他に図示しない凹部もある。
【0011】
また、図1の陳列棚(1)は、支柱(2)を1対しか有していない単連の棚であるが、支柱(2)が左右方向に3本以上配列された多連の棚の中間の支柱には、係止孔(7)と受入部を、支柱の左右両側面に形成する。
【0012】
図3において、左右方向を向いた上部連結杆(3)は、断面下向きコ字状に形成され、その左右両端に、ブラケット(12)がねじ(13)によって取付けられている。
ブラケット(12)の先端部には、前後1対の下向きフック状の係止爪(14)と、この係止爪(14)の間に位置する下向きの弾性舌片(15)とが形成されている。弾性舌片(15)のほぼ中央には、支柱(2)の上部に形成された貫通孔(11)に嵌合する突部(10)が、外向きに突設されている。
【0013】
図4において、左右方向を向く下部連結杆(4)は、断面ほぼ上向きコ字状の連結杆本体(16)と、この連結杆本体(16)に被さる断面下向きコ字状のカバー(17)とを備えている。連結杆本体(16)の上部は、前後に屈曲し、その屈曲部(16a)には、ねじ(18)によってカバー(17)が取付けられ、両者(16)(17)が一体化されている。
【0014】
連結杆本体(16)の左右両端には、前後1対の係止爪(14)が下向きに、かつ弾性舌片(19)が上向きに形成されている。なお、係止爪(14)は、上下2段に形成されており、その上下間隔は、支柱の下部に形成された係止孔(8)の上下間隔と同じである。
【0015】
弾性舌片(19)には、支柱(2)の下部に設けた貫通孔(11)に嵌合する突部(10)が、外向きに突設されている。
以上説明した前後1対の係止孔(7)(8)と係止爪(14)の前後間隔は、同一である。また、係止孔(7)(8)のスリット幅は、係止爪(14)の厚さよりやや広く形成されている。
【0016】
次に、支柱(2)と連結杆(3)(4)の連結の手順について説明する。
先ず、1対の支柱(2)を左右方向に配設し、支柱下部の係止孔(7)に下部連結杆(4)の係止爪(14)を落とし込むようにして係合させるとともに、突部(10)を貫通孔(11)に嵌合させる。
その後、支柱上部の係止孔(7)に、上部連結杆(3)の係止爪(14)を支柱(2)の上方から落とし込むようにして係合させる。これと同時に、突部(10)を貫通孔(11)に嵌合させる。
【0017】
突部(10)を貫通孔(11)に嵌合させるとき、弾性舌片(15)(19)は、一旦、支柱(2)から離れる方向に撓んだ後、弾力によって戻り、その後は、突部(10)が貫通孔(11)から外れないよう嵌合状態を保持する。特に、支柱上部の貫通孔(11)は、弾性片(9)に形成されているため、弾性片(9)と弾性舌片(15)とが互いに押し合って、突部(10)と貫通孔(11)との嵌合状態が確実に保持される。
【0018】
これによって、ボルトとナットを使用せず、支柱(2)に上部、及び下部連結杆(3)(4)をワンタッチで組み付けることができる。
また、支柱(2)と上部、及び下部連結杆(3)(4)との分解は、マイナスドライバーのような先端が扁平な工具を、支柱(2)と弾性舌片(15)(19)との間に差し込み、弾性舌片(15)(19)を支柱(2)から離れる方向に撓ませて、突部(10)を貫通孔(11)から外した後、上部、及び下部連結杆(3)(4)を持ち上げることによって、可能である。
従って、支柱(2)と上部、及び下部連結杆(3)(4)との分解もワンタッチで簡単に行なうことができる。
【0019】
なお、この連結装置は、棚類の支柱と連結杆との連結固定の他に、プレハブ式の簡易物置、家屋等における支柱と連結杆とを連結することもでき、本発明の連結装置は、棚類の支柱と連結杆との連結のみに限定されるものではない。
【0020】
【発明の効果】
請求項1の発明の連結装置は、支柱と連結杆とを、係止孔と係止爪との係合と、突部と受入部との嵌合とによって連結させているため、支柱と連結杆との組立、分解を容易に行なえるとともに、支柱と連結杆との相対位置ずれを防止して、強固に連結することができる。
【0021】
部と受入部とのいずれか一方を、弾性舌片に設けてあるので、その弾性舌片を弾性撓曲させることにより、突部と受入部とを容易に嵌合させることができるとともに、一度それらが嵌合すると、弾性舌片の弾力により、その嵌合状態が保持され、支柱と連結杆とを強固に連結することができる。
【0022】
止孔を、支柱の上端に開口するように支柱に形成してあるので、係止爪を係合孔に落とし込むだけで、連結杆を支柱に組み付けることができるため、組立が容易になる。
【0023】
止孔と係止爪とを前後に1対形成し、かつそれらの間に突部と受入部とを配設してあるので、支柱のねじれや連結杆の前後方向への傾きを阻止することができるとともに、突部と受入部との外れ防止することができ、支柱と連結杆とを確実に連結することができる。
