Description

【0001】
【発明の属する技術分野】
本発明は、住宅や事務所の部屋、トイレ、風呂場等の三角コーナ部の壁面に取り付けて使用されるコーナ棚に関するものである。
【0002】
【従来の技術】
部屋等の三角コーナ部の壁面にコーナ棚を取り付ける通常の方法は、L字形金具などを用いて、コーナ壁面にコーナ棚を釘付けしたり、ネジ締めしたりする方法である。しかしこの取り付け方法では、別部材のL字形金具などを用いるため、取り付け作業が煩雑になると共に、見栄えが悪いという問題があり、特にコーナ壁面からコーナ棚を取り外す作業が困難であるという問題があった。
【0003】
このような問題点を解消するため、実用新案第303098号公報にL字形金具などの別部材を用いることなく、比較的簡便にコーナ壁面に対する取り付け、取り外し作業を行えるコーナ棚が提案されている。この従来例は図16に示すように、コーナ棚本体51にスライド可能に収容されると共に先端に針52を備えた左右の針付きスライダ53を有し、コーナ棚本体51の裏面に設けた操作つまみ54を回転させることにより、この回転動作をベベルギヤ55、回転シャフト56等を介して左右の針付きスライダ53の進退動に変換するように構成したものである。この従来例によれば、前記操作つまみ54を正方向に回転することにより、左右の針付きスライダ53を外方に移動させて、これらの針52をコーナ壁面に突き刺してコーナ棚を取り付けることができ、また前記操作つまみ54を逆方向に回転することにより、左右の針付きスライダ53を内方に移動させて、これらの針52をコーナ壁面から抜き取り、コーナ棚を取り外すことができる。
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来例では、操作つまみ、ベベルギヤ、回転シャフト等を設ける必要があって、構造が複雑で高価になると共に、嵩張ってコンパクトに構成することが困難になり、また見栄えが悪くなるという問題があった。また針付きスライダをコーナ壁面に突き刺すために大きな力を要するのであるが、そのためには操作つまみ1回転当りの針付きスライダの移動量を小さく設定する必要があって、コーナ棚の取り付け、取り外しを完了するまでには操作つまみを多数回回転させなければならず、作業に比較的長い時間を要するという問題点もあった。
【0005】
【課題を解決するための手段】
本発明のコ−ナ棚は上記従来例の問題点を解消するため、コーナ壁面に接する左右取付面と正面とを側周に備えた棚本体と、それぞれ棚本体にスライド可能に収容されると共に先端に針を備えた左右の針付きスライダと、棚本体に正面から挿脱可能に挿入される操作板とを備え、操作板の表面には押出し用カムが、裏面には引込み用カムがそれぞれ形成され、操作板の表面を上下の一方側に向けて棚本体内に挿入して押動すると、前記押出し用カムにより左右の針付きスライダが外方に移動してそれぞれの針が前記左右取付面の外方に突出し、操作板の裏面を前記上下の一方側に向けて棚本体内に挿入して押動すると、前記引込み用カムにより左右の針付きスライダが内方に移動してそれぞれの針が前記左右取付面の内方に退入するように構成したことを特徴とする。
【0006】
上記発明において、左右の針付きスライダは基端側にカム従動用突部を備え、押出し用カムは先端側に三角形状に突出するカム面部を備えて、操作板の前進により前記カム面部に接する左右の前記カム従動用突部を介して左右の針付きスライダが外方に移動するように構成される一方、引込み用カムは先端側にハ字状に開くカム面部を備えて、操作板の前進により前記カム面部に接する左右の前記カム従動用突部を介して左右の針付きスライダが内方に移動するように構成されていると好適である。
【0007】
本発明は、実施形態に示される略二等辺直角三角形の板状棚本体を有するコーナ棚に適用しうる外、図16に示す平面視形状が略四分の一円形(扇形)のものや、平面視形状が略五角形のもの等にも適用でき、この場合には円弧面等が本発明で云う正面となる。
【0008】
また本発明のコーナ棚には、キャビネット、抽き出し、吊り棚等を棚本体に一体的に備えた、いわゆるコーナ部設置家具が含まれている。
【0009】
また本発明の左右針付きスライダは、実施形態に示されるように、前後2組備わっている場合の外、3組以上の場合や単に1組のみの場合であってもよい。
【0010】
さらに上記発明のコーナ棚では、1枚の操作板に押出し用カムと引込み用カムとを形成し、構造の一層の簡単化を図っているが、多少この点を犠牲にして、押出し用カムが形成された取り付け用操作板と、引込み用カムが形成された取り外し用操作板との2枚の操作板を有する構造とすることも可能である。
【0011】
【発明の効果】
本発明によれば、板状の操作板の挿入押動動作によって、左右の針付きスライダを進退動させることができ、しかも好適には1枚の操作板によりコーナ棚の取り付け、取り外しの両作業を行うことができるので、構造が簡単で安価なものとすることができる上に、コンパクトで見栄えの良いものとすることができる。また操作板に形成した押出し用カムや引込み用カムを利用して、操作板の押動操作で針付きスライダの進退動を行うので、コーナ棚の取り付け、取り外し作業を迅速に行うことができる。
【0012】
【発明の実施の形態】
以下、本発明の実施形態について、図面を参照しながら説明する。
【0013】
図1〜図7において、1は平面視形状が略二等辺直角三角形で板状の棚本体であって、上板2と下板3とを接着一体化して構成されている。この棚本体1の側周に位置する左右の面は、コーナ壁面4L、4Rに接する左取付面5L、右取付面5Rとなっていて、両者は同長で直角に交っている。前記棚本体1の側周の前側に位置する正面6には、操作板7を挿脱可能に案内する操作板ガイド穴8が、正面6の中央部からこれに直交する方向に奥側に向けて設けられている。左取付面5Lの前側には前側の左針付きスライダ9Lをスライド可能に案内する左前案内穴10Lが、左取付面5Lの後側には後側の左針付きスライダ11Lをスライド可能に案内する左後案内穴12Lが、それぞれ左取付面5Lに開口するようにして設けられている。右取付面5Rの前側には前側の右針付きスライダ9Rをスライド可能に案内する右前案内穴10Rが、右取付面5Rの後側には後側の右針付きスライダ11Rをスライド可能に案内する右後案内穴12Rが、それぞれ右取付面5Rに開口するようにして設けられている。図1に示すように、左前案内穴10Lと右前案内穴10Rとは、正面6に平行に一直線上に位置するように設けられ、それぞれの内端は前記操作板ガイド穴8に交わってこれと連通している。左後案内穴12Lと右後案内穴12Rとは、正面6に平行に一直線上に位置するように設けられ、それぞれの内端は前記操作板ガイド穴8に交わってこれと連通している。上記4つの案内穴10L、10R、12L、12Rは、横断面形状が同一の長方形状である。なお、棚本体1の上面13および下面14は平坦面に形成されている。
【0014】
前記上板2は樹脂板からなり、その下面に前記操作板ガイド穴8、各案内穴10L、10R、12L、12R等を構成するための凹凸部が一体形成されている。前記下板3は樹脂板からなり、その上面に前記操作板ガイド穴8等を構成するための凹凸部が一体形成されている。
【0015】

【0016】
前記押出し用カム16は、図5に示すように、操作板7の中心線に対し左右対称の略T形状の板状カムであって、基端側に広幅部19を有すると共に先端側に鋭角の二等辺三角部21を有し、その2辺がカム面(カム面部)18、18となっている。また押出し用カム16の広幅部19の近傍位置には指掛け用凹部20が形成されている。
【0017】
前記引込み用カム17は、図6に示すように、操作板7の中心線に対し左右対称の略U形状の板状カムであって、基端辺部22と左右の側辺部23、23とからなり、両側辺部23、23の先端部の内面側が斜めに切欠かれたカム面(カム面部)24、24となっている。両カム面24、24は先端側に向けてハ字状に開き、両者のなす角は鋭角となっている。
【0018】
前記押出し用カム16の広幅部19の左右端および前記引込み用カム17の両側辺部23、23の左右端に対し前記基板部15の左右端がそれぞれ側方に張り出した位置にあり、図5等に示すようにこの左右の張出部25、25が棚本体1の操作板ガイド穴8の両内側面に設けた溝26、26に嵌合するようになっている。
【0019】
前記操作板7の基端面27の形状は、図2、図3、図5に示すように、横長の長方形を基本形状とし、その両側面に前記張出部25、25が突出する形状となっているが、棚本体1の操作板ガイド穴8の横断面形状も同様の形状となっていて、操作板7が操作板ガイド穴8に案内されてスムースに前後動できるように構成されている。また図1に示すように、操作板7を操作板ガイド穴8の最奥まで挿入したとき、操作板7の基端面27が棚本体1の正面6と面一となるように構成されている。
【0020】
棚本体1の下面14の正面側左右方向中央には、図4に示すように、切欠窓部28を設け、前記指掛け用凹部20や前記基端辺部22を利用して、操作板7を引き出しやすくしている。
【0021】
前記前側の左針付きスライダ9Lは、図1、図7〜図11に示すように、樹脂製のスライダ本体29の外端面30に植設された2本の金属製の針31、31を備えると共に、内端側下面にカム従動用突部32を一体に備えている。
【0022】
前記スライダ本体29の横断面形状は、棚本体1の左前案内穴10Lのそれと同一の長方形状となっている。そして前記針付きスライダ9Lは、図1に示すように、前記左前案内穴10L内に左右動自在に収容され、その左右動によって前記針31、31が棚本体1の左取付面5Lから出没するように構成されている。前記針31、31が図6等に示すように、最大限外部に突出するとき、スライダ本体29の外端面30が前記左取付面5Lと面一となるよう、外端面30は斜面に形成されている。
【0023】
前記スライダ本体29の内端側部分は、図7、図9に示すように下面側が抉られて薄肉部33となっており、この薄肉部33の下面に前記カム従動用突部32が円柱状に一体形成されている。スライダ本体29の薄肉部33以外の部分の下面と、前記カム従動用突部32の下端面とは同一高さ位置にある。
【0024】
前記前側の右針付きスライダ9Rは、前記前側の左針付きスライダ9Lと左右対称な形状に形成され、同様に2本の針31、31、カム従動用突部32を備え、同様に前記右前案内穴10R内に左右動自在に収容されている。
【0025】
前記後側の左右の針付きスライダ11L、11Rは、互いに左右対称となる形状を有している。また後側の左右針付きスライダ11L、11Rは、図1、図12、図13に示すように、外端面30に1本の針31しか有さず、又短寸である点で前側の針付きスライダ9L、9Rと相違している点を除き、これと基本的に同一形態に形成され、同様のカム従動用突部32を備えると共に、同様に前記左後案内穴12Lおよび右後案内穴12Rに左右動自在に収容されている。
【0026】
次に前記操作板7の挿入押動操作と各針付きスライダ9L、9R、11L、11Rの動きの関係につき説明する。
【0027】
前記操作板7を図5、図14に示すように、押出し用カム16が形成された表面を上側にして、前記操作板ガイド穴8に挿入して押動すると、各針付きスライダ9L、9R、11L、11Rのカム従動用突部32に押出し用カム16のカム面18、18が当接して、各針付きスライダ9L、9R、11L、11Rを左右方向外方に移動させ、それぞれの針31が棚本体1の左右取付面5L、5Rの外方に突出するように構成されている。図14の(a)は、各針付きスライダ9L、9R、11L、11Rが退入位置にあって、棚本体1に挿入された操作板7の押出し用カム16のカム面18、18が前側の左右針付きスライダ9L、9Rのカム従動用突部32に当接する直前の状態を示している。この状態からさらに操作板7を前進させると、図14の(b)に示すように、前側の左右針付きスライダ9L、9Rは押出し用カム16によって左右方向外方に移動させられ、これらの外端面30が棚本体1の左右取付面5L、5Rと面一となる位置に達し、これらの針31は完全に外方に突出する。続いて操作板7を前進させると、後側の左右針付きスライダ11L、11Rは押出し用カム16によって左右方向外方に移動させられ、これらの外端面30が前記左右取付面5L、5Rと面一となる位置に達し、これらの針31も完全に外方に突出する。図14の(c)は、操作板7を最奥位置まで挿入した状態を示しているが、この(c)に示すように、各針付きスライダ9L、9R、11L、11Rの針31は、棚本体1の左右取付面5L、5Rの外方に突出しているのである。
【0028】
一方前記操作板7を図1、図6、図15に示すように、引込み用カム17が形成された裏面を上側にして、前記操作板ガイド穴8に挿入して押動すると、各針付きスライダ9L、9R、11L、11Rのカム従動用突部32に引込み用カム17のカム面24、24が当接して、各針付きスライダ9L、9R、11L、11Rを左右方向内方に移動させ、それぞれの針31が棚本体1の左右取付面5L、5Rの内方に退入するように構成されている。図15の(a)は、各針付きスライダ9L、9R、11L、11Rが突出位置にあって、棚本体1に挿入された操作板7の引込み用カム17のカム面24、24が前側の左右針付きスライダ9L、9Rのカム従動用突部32に当接する直前の状態を示している。この状態からさらに操作板7を前進させると、図15の(b)に示すように、前側の左右針付きスライダ9L、9Rは引込み用カム17によって左右方向内方に移動させられ、最内方に達し、これらの針31は棚本体1の左右取付面5L、5Rの内方に退入する。続いて操作板7を前進させると、後側の左右針付きスライダ11L、11Rは引込み用カム17によって左右方向内方に移動させられ、最内方に達し、これらの針31も前記左右取付面5L、5Rの内方に退入する。そして図1に示すように、操作板7を最奥位置まで挿入したとき、各針付きスライダ9L、9R、11L、11Rの針31は、棚本体1の左右取付面5L、5Rの内方に退入しているのである。
【0029】
なお操作板7の挿入押動操作によって、各針付きスライダ9L、9R、11L、11Rの上記移動がスムースになされるよう、各カム面18、24と各カム従動用突部32との位置関係等が、図面に示すように、適正に定められている。また上記実施形態では、操作板7の挿入方向と各針付きスライダ9L、9R、11L、11Rの移動方向とが直交する関係となっているが、直交しなくてもよい。
【0030】
次に上記構成のコーナ棚を部屋の三角コーナ部の壁面4L、4Rに取り付ける作業について説明する。
【0031】
先ず、棚本体1を、その左右取付面5L、5Rがコーナ壁面4L、4Rに接するようにして保持し、次いで押出し用カム16が形成された表面を上側に向けて操作板7を棚本体1の正面6の操作板ガイド穴8に挿入して押し込む。この押し込み力によって図14の(a)〜(c)で説明したように、各針付きスライダ9L、9R、11L、11Rは左右方向外方に移動し、各々の針31がコーナ壁面4L、4Rに刺し込まれ、コーナ棚の取り付け作業が終了する。通常のコーナ壁面4L、4Rに対しては、操作板7の押動力が押出し用カム16の増力作用(カム面18、18間のなす角が小さい程増力倍率は大となる。)によって増大されるので、人の押し込み力だけで十分コーナ棚の取り付け作業を行うことができるが、コーナ壁面4L、4Rが硬い材質のものである場合などは、木ハンマーなどによって操作板7を打ち込むことによって、前記取り付け作業を行えばよい。
【0032】
コーナ棚の取り付け作業が終了すると、前記操作板7は棚本体1内にそのまま収容され、その基端面27は棚本体1の正面6と面一状態になり、見栄えが悪くなるのを防ぐと共に、コーナ棚の取り外し作業時にすぐに使える状態にしておくことができる。
【0033】
次に上記コーナ棚を前記コーナ壁面4L、4Rから取り外す作業について説明する。
【0034】
先ず、棚本体1に収容されている操作板7を前記操作板ガイド穴8から抜き取る。次いで操作板7の上下を逆にして、引込み用カム17が形成された裏面を上側に向けて操作板7を前記操作板ガイド穴8に挿入して押し込む。この押し込み力によって図15の(a)、(b)および図1で説明したように、各針付きスライダ9L、9R、11L、11Rは左右方向内方に移動し、各々の針31は壁面4L、4Rから抜け、コーナ棚の取り外し作業を行うことができる。この取り外し作業は、一旦コーナ壁面4L、4Rに刺し込まれた針31を抜き取るだけでよく、抜き取るための力はそれほど大きなものは必要ではないので人の押し込み力だけで十分である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a corner shelf used by being attached to a wall surface of a triangular corner portion of a room of a house or office, a toilet, a bathroom, or the like.
[0002]
[Prior art]
A usual method of attaching a corner shelf to the wall surface of a triangular corner portion of a room or the like is a method of nailing the corner shelf to the wall surface of the corner using an L-shaped bracket or the like or tightening screws. However, in this mounting method, since a separate member such as an L-shaped bracket is used, the mounting operation is complicated and the appearance is poor. In particular, it is difficult to remove the corner shelf from the corner wall surface. Was.
[0003]
In order to solve such problems, Japanese Utility Model No. 303098 proposes a corner shelf that can be relatively easily attached to and detached from a corner wall without using another member such as an L-shaped bracket. As shown in FIG. 16, this conventional example has left and right needle-attached sliders 53 slidably housed in a corner shelf main body 51 and provided with needles 52 at the tips, and is provided on the back surface of the corner shelf main body 51. By rotating the knob 54, the rotation is converted into forward and backward movements of the left and right needle sliders 53 via the bevel gear 55, the rotating shaft 56 and the like. According to this conventional example, by rotating the operation knob 54 in the forward direction, the sliders 53 with left and right needles are moved outward, and the needles 52 are pierced into the corner wall surface to mount the corner shelf. By rotating the operation knob 54 in the opposite direction, the left and right needle sliders 53 can be moved inward, the needles 52 can be pulled out from the corner wall surface, and the corner shelf can be removed.
[0004]
[Problems to be solved by the invention]
However, in the above-mentioned conventional example, it is necessary to provide an operation knob, a bevel gear, a rotating shaft, and the like, so that the structure is complicated and expensive, and it is difficult to make the device bulky and compact, and the appearance is deteriorated. There was a problem. In addition, a large force is required to penetrate the needle slider with the corner wall surface. For this purpose, it is necessary to set a small amount of movement of the needle slider per rotation of the operation knob. Until the operation is completed, the operation knob must be rotated many times, and there is a problem that the operation requires a relatively long time.
[0005]
[Means for Solving the Problems]
In order to solve the problems of the above-described conventional example, the corner shelf of the present invention is provided with a shelf main body having left and right mounting surfaces and a front surface in contact with a corner wall surface on the side circumference, and slidably accommodated in the shelf main body, respectively. A slider with left and right needles with needles at the tip, and an operation plate that can be inserted and removed from the front of the shelf body from the front, a push-out cam on the front surface of the operation plate, and a retraction cam on the back surface When the surface of the operation plate is inserted into the shelf main body with the surface of the operation plate directed to one of the upper and lower sides and pushed, the slider with the left and right needles is moved outward by the pushing cam, and the respective needles are attached to the left and right sides. When the rear side of the operation plate is inserted into the shelf main body with the back surface of the operation plate facing one of the upper and lower sides and pushed, the left and right needle sliders are moved inward by the retracting cam, and the respective sliders are moved inward. Make sure that the needle retracts inside the left and right mounting surfaces. Characterized in that it was.
[0006]
In the above invention, the left and right needle sliders have a cam follower projection on the base end side, and the pushing cam has a triangularly protruding cam surface section on the distal end side, and comes into contact with the cam surface section by advancing the operation plate. The left and right needle sliders are configured to move outward through the left and right cam follower protrusions, while the retracting cam has a cam surface portion that opens in a C-shape on the tip side, It is preferable that the left and right needle sliders be configured to move inward via the left and right cam follower protrusions that come into contact with the cam surface portion by advancing.
[0007]
The present invention can be applied to a corner shelf having a plate-shaped shelf body of a substantially isosceles right triangle shown in the embodiment, and a plane view shape shown in FIG. The present invention can also be applied to a device having a substantially pentagonal shape in plan view, and in this case, an arc surface or the like is the front in the present invention.
[0008]
The corner shelves of the present invention include so-called corner-installed furniture in which cabinets, drawers, hanging shelves, and the like are integrally provided on the shelf body.
[0009]
Further, as shown in the embodiment, the slider with left and right needles of the present invention may be provided with two sets of front and rear needles, but may be provided with three or more sets or simply with one set.
[0010]
Further, in the corner shelf of the invention described above, an extrusion cam and a retraction cam are formed on a single operation plate to further simplify the structure, but at the expense of this point, the extrusion cam is used. It is also possible to adopt a structure having two operation plates, that is, a mounting operation plate formed and a detachment operation plate formed with a retracting cam.
[0011]
【The invention's effect】
