Description

【0001】
【発明の属する技術分野】
この発明は収容ケースに使用することを前提とした車輪部材及びそれを使用した収容ケースに関する。
【0002】
【従来の技術】
衣類や日用品を収容するためのプラスチック製の収納ケースが公知である。この種の収納ケースは押し入れやクローゼット等の収納スペースや、家具間の隙間やベランダ等のデッドスペースを利用して置かれることが一般的であり、又、多段式に積み重ねられて使用されることも多かった。
【0003】
そのため、恒常的に設置されるインテリア家具と異なり、一旦置いたものを必要に応じて移動させたりずらせたりする機会が多く、移動を容易にするために底部に車輪を設置することが従来から行われていた。この場合、車輪としてキャスターを使用するものの他、収納ケース自体に車輪を組み込んだもの(例えば、特開平8−64657)が公知であった。
【0004】
【発明が解決しようとする課題】
前記の従来技術のうちの前者のものにおいては、収納ケースに対する回動軸を備えたキャスター本体に車輪を回転自在に保持するというキャスターの構造上、製造コストが嵩む問題があった。更に、回動軸の分の高さが増す結果、その分収納ケース自体の高さが高くなり、限られたスペースに置くことを考慮した場合この問題は無視できなかった。又、後者のものにおいては、車輪による移動を望まない需要者においては車輪を取り外す作業が面倒であるいう問題があり、これは前者にも共通する問題であった。更に、以上の従来技術には収納ケースに対し、車輪による転動機能を付加するかしないかの二者択一的な発想しかなく、車輪及びそれの取り付け機構をそれ以外の用途に活用するという発想がなかった。
【0005】
【課題を解決するための手段】
この発明は以上の従来技術の問題点に鑑みて創作されたものであり、単に従来技術の問題点を解消するに止まらず、更にそれに新たな機能を付加することを可能とした車輪部材を提供することを目的とする。
【0006】
【課題を解決するための手段】
即ち、この発明の車輪部材は下記(イ)の構成よりなる車輪部材を挿入する挿入凹部を底部又は底部及び天井部に設けると共に、上記挿入凹部の形状を車輪部材を異なる2方向に挿入可能な形状としたことを特徴とする。
(イ)上下端の少なくとも一方を開口部とした中空状の車輪ケースと、転動面が開口部より外部に露出するようにこの車輪ケース内に回転自在に設けられる車輪からなり、車輪ケースの上下方向の中途周側には外方に突出した係止突起が設けられ、この係合突起の上下の車輪ケースの周側形状は同一であることを特徴とする車輪部材
【0007】
【発明の実施の形態】
図1乃至図5はこの発明の車輪部材の実施例を示す図である。この発明の車輪部材は車輪6とそれが収容される車輪ケース2から構成される。車輪ケース2はプラスチックにより一方を開口部3とした中空状に構成されるものであり、ここでは周側形状が矩形の直方体に構成される。そして、車輪ケース2の上下方向の中途周側には外方に突出した係止突起4が設けられ、ここでは係止突起は車輪ケースの外周に渡り連続するフランジ状突起として構成される。この場合、係合突起の上下の車輪ケースの周側部分2A及び2Bの形状は同一であることが必須であり、これはこの発明の特徴部分である。
【0008】
次に車輪6はプラスチックにより一体に成形した回転軸7が両側に突出するよう構成されるものであり、車輪ケース2の開口部3の両側壁面に設けられた下端を開放側とした円状の切り欠き溝5、5に回転軸7が嵌め込まれることにより、転動面が開口部より外部に露出した状態で車輪ケース内に回転自在に設けられる。この場合、車輪ケース2の切り欠き溝5、5の円の直径は車輪6の回転軸7の直径より大に構成されると共に、切り欠き溝の開放側の幅は回転軸の直径より小に構成される。その結果、車輪6の回転軸7を車輪ケース2の切り欠き溝5に対し開放側から圧入すれば両者の変形により回転軸は開放側を通過して切り欠き溝内に遊嵌・保持されることとなる。
【0009】
尚、以上の実施例において、車輪ケース2は上下に開口部を設けてもよく、又、周側形状は矩形に限らず、正方形であってもよいことは勿論である。
【0010】
図6乃至1はこの発明の車輪部材を使用した収容ケースの参考例を示す図である。ここでは収容ケースとして多段式に積み重ね可能なプラスチック製の収納ケース(便宜上、下段の収容ケースの符号を11A、上段の収容ケースの符号を11Bとする。)を想定している。これらの収容ケースの底部には車輪部材1を挿入するための挿入凹部11A(11B)が4箇所に設けられる(図11参照)。又、下段の収容ケースの天井部には車輪部材1を挿入するための挿入凹部13Aが4箇所に設けられる。これらの場合において、挿入凹部11A(13A、11B)は車輪部材の車輪ケース2の周側形状に合致した形状に構成されるが、前記の実施例においては車輪ケースの円状の切り欠き溝に遊嵌・保持された車輪の回転軸7端が車輪ケースより突出するので、ここではこの部分を逃げるための凸状の逃げ部12A、12Aが挿入凹部の両側に設けられる(図10参照)。尚、収容ケースの底部に設けられる挿入凹部11A(11B)は車輪部材1の脱落を防ぐために、この実施例では車輪部材の車輪ケース2の外形より若干小さく構成し、プラスチックの弾性を利用して車輪ケースが嵌入・保持されるように構成している。一方、収容ケースの天井部に設けられる挿入凹部13Aは上記のような必要がなく、逆に積み重ねた上段の収納ケースを容易に持ち上げることを可能とするために、車輪部材の車輪ケース2の外形より若干大きく構成して遊嵌するように構成している。
【0011】
車輪部材1は使用に当たっては収納ケースの挿入凹部11A(13A、11B)に挿入されるが、図7に示すようにこの場合に周側の係止突起4が挿入凹部の周側に当接することによりそれ以上の挿入を規制するためのストッパーとなる。
【0012】
以上の構成よりなる収納ケースに対し、車輪部材は次のように使用可能である。
(1) 下段に位置する収容ケース10Aの底部の挿入凹部11Aに、車輪部材1の車輪ケースの2A側を挿入することにより車輪6の転動面が収容ケースの下方に位置し、収納ケースの移動用の車輪となる(図6及び図7参照)。
(2) 車輪部材1を上下に反転し、車輪ケースの2B側を下段に位置する収容ケース10Aの底部の挿入凹部11Aに挿入することにより車輪部材の非車輪側が収容ケースの下方に位置し、収納ケースの載置用のアジャスターとなる(図8参照)。
(3) 車輪部材1の車輪ケースの2B側を上段に位置する収容ケース10Bの底部の挿入凹部11Bに挿入すると共に、車輪ケースの2A側を下段に位置する収容ケース10Aの天井部の挿入凹部13Aに挿入することにより上下の収容ケースを結合するためのジョイントとなる(図6及び図9参照)。尚、この場合、車輪部材の上下は逆であってもよい。
【0013】
図12乃至14はこの発明の収納ケースの実施例を示す図である。この実施例においては底部に設けられる挿入凹部20Aを十字形状とすることによりは、車輪部材1を異なる2方向に挿入可能としている。即ち、図13に示すように車輪部材の車輪の回転方向を収容ケース10Aの前後方向に合致するように車輪ケース2を挿入すれば収納ケースは前後方向に移動可能となり、図14に示すように車輪部材の車輪の回転方向を収容ケース10Aの左右方向に合致するように車輪ケース2を挿入すれば収納ケースは左右方向に移動可能となる。
【0014】
【発明の効果】
以上の構成よりなるこの発明は次の特有の効果を奏する。
(1) 車輪を組み込んだ車輪部材を収納ケースの挿入凹部に挿入するだけで車輪を収納ケースに装着できるので、需要者において必要に応じてワンタッチで収納ケースへ車輪を脱着できる。
(2) 車輪ケースの上下方向の中途周側に外方に突出した係止突起が設けられ、この係合突起の上下の車輪ケースの周側形状は同一であるので、車輪部材を反転して収納ケースの挿入凹部に挿入すれば車輪部材の非車輪面が収容ケースの下方に位置し、車輪部材を収納ケースの載置用のアジャスターとして利用できる。
(3) 同様に、車輪部材を上下の収納ケースの挿入凹部間に挿入すれば、上下の収納ケースを結合するジョイントとして利用できる。
(4) 以上のように、車輪部材を多目的に利用できるので、従来それぞれの用途に応じて複数種用意していた部材が一本化され製造効率が合理化してコストダウンに寄与する。一方、需要者においても、一種類の部材をもって収納ケースの組み合わせ及び機能を自由に組み換えることが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a wheel member premised on use in a storage case and a storage case using the same.
[0002]
[Prior art]
A plastic storage case for storing clothing and daily necessities is known. This type of storage case is generally placed using storage spaces such as closets and closets, gaps between furniture, and dead spaces such as verandas, and is used by being stacked in multiple stages. There were also many.
[0003]
For this reason, unlike interior furniture that is always installed, there are many opportunities to move and displace items once placed as necessary, and wheels have been conventionally installed at the bottom to facilitate movement. It was broken. In this case, in addition to those using casters as wheels, those in which wheels are incorporated in the storage case itself (for example, JP-A-8-64657) have been known.
[0004]
[Problems to be solved by the invention]
The former of the above prior arts has a problem that the manufacturing cost increases due to the structure of the caster in which the wheel is rotatably held on the caster main body having a rotation shaft for the storage case. Furthermore, as a result of the height of the rotating shaft being increased, the height of the storage case itself is increased accordingly, and this problem cannot be ignored when considering placing in a limited space. In the latter case, there is a problem that the operation of removing the wheel is troublesome for a consumer who does not want to move by the wheel, and this is a problem common to the former. Furthermore, the above prior art has only an alternative idea of whether or not to add a rolling function by wheels to the storage case, and the wheel and its mounting mechanism are used for other purposes. There was no idea.
[0005]
[Means for Solving the Problems]
The present invention was created in view of the above-mentioned problems of the prior art, and provides a wheel member that not only solves the problems of the prior art but also allows new functions to be added thereto. The purpose is to do.
[0006]
[Means for Solving the Problems]
That is, the wheel member of the present invention is provided with an insertion recess for inserting the wheel member having the following configuration (a) in the bottom or the bottom and the ceiling, and the shape of the insertion recess can be inserted in two different directions. It is characterized by its shape.
(B) a hollow wheel case having at least one of upper and lower ends as an opening and a wheel rotatably provided in the wheel case so that the rolling surface is exposed to the outside from the opening. A wheel member characterized in that a locking projection protruding outward is provided on the middle circumferential side in the vertical direction, and the circumferential shape of the upper and lower wheel cases of the engagement projection is the same .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
1 to 5 are views showing an embodiment of the wheel member of the present invention. The wheel member of the present invention includes a wheel 6 and a wheel case 2 in which the wheel 6 is accommodated. The wheel case 2 is formed in a hollow shape with one opening 3 made of plastic, and here, the peripheral side shape is formed in a rectangular parallelepiped. And the latching protrusion 4 which protrudes outward is provided in the middle peripheral side of the up-down direction of the wheel case 2, and the latching protrusion is comprised as a flange-shaped protrusion which continues over the outer periphery of a wheel case here. In this case, it is essential that the peripheral side portions 2A and 2B of the upper and lower wheel cases of the engaging projections have the same shape, which is a characteristic portion of the present invention.
[0008]
Next, the wheel 6 is configured such that a rotating shaft 7 integrally formed of plastic protrudes on both sides, and has a circular shape with lower ends provided on both side walls of the opening 3 of the wheel case 2 as open sides. When the rotary shaft 7 is fitted into the notched grooves 5 and 5, the rolling surface is provided rotatably in the wheel case with the rolling surface exposed to the outside through the opening. In this case, the diameter of the circle of the notch grooves 5 and 5 of the wheel case 2 is configured to be larger than the diameter of the rotating shaft 7 of the wheel 6, and the width of the notch groove on the open side is smaller than the diameter of the rotating shaft. Composed. As a result, if the rotary shaft 7 of the wheel 6 is press-fitted into the cutout groove 5 of the wheel case 2 from the open side, the rotary shaft passes through the open side and is loosely fitted and held in the cutout groove due to deformation of both. It will be.
[0009]
In the above embodiment, the wheel case 2 may be provided with openings at the top and bottom, and the peripheral shape is not limited to a rectangle, but may be a square.
[0010]
6 to 1 1 is a diagram showing a reference example of the housing case using the wheel member of the present invention. Here, it is assumed that the storage case is a plastic storage case that can be stacked in a multistage manner (for convenience, the lower storage case is denoted by 11A and the upper storage case is denoted by 11B). Insertion recesses 11 </ b> A (11 </ b> B) for inserting the wheel member 1 are provided at four locations on the bottoms of these storage cases (see FIG. 11). Further, four insertion recesses 13A for inserting the wheel member 1 are provided in the ceiling portion of the lower storage case. In these cases, the insertion recess 11A (13A, 11B) is configured in a shape that matches the circumferential shape of the wheel case 2 of the wheel member, but in the embodiment described above, the insertion recess 11A (13A, 11B) is formed in the circular notch groove of the wheel case. Since the end of the rotary shaft 7 of the loosely fitted and held wheel protrudes from the wheel case, convex relief portions 12A and 12A for escaping this portion are provided on both sides of the insertion concave portion (see FIG. 10). In this embodiment, the insertion recess 11A (11B) provided at the bottom of the housing case is configured to be slightly smaller than the outer shape of the wheel case 2 of the wheel member in order to prevent the wheel member 1 from falling off. The wheel case is configured to be fitted and held. On the other hand, the insertion recess 13A provided in the ceiling portion of the storage case does not need to be as described above, and conversely, the outer shape of the wheel case 2 of the wheel member can be easily lifted so that the upper storage case stacked can be easily lifted. It is configured to be slightly larger and loosely fitted.
[0011]
When the wheel member 1 is used, it is inserted into the insertion recess 11A (13A, 11B) of the storage case. As shown in FIG. 7, in this case, the circumferential locking projection 4 abuts the circumferential side of the insertion recess. Therefore, it becomes a stopper for restricting further insertion.
[0012]
The wheel member can be used as follows for the storage case having the above-described configuration.
(1) By inserting the 2A side of the wheel case 1 of the wheel member 1 into the insertion recess 11A at the bottom of the storage case 10A located at the lower stage, the rolling surface of the wheel 6 is positioned below the storage case, It becomes a wheel for movement (refer to Drawing 6 and Drawing 7).
(2) The wheel member 1 is turned upside down, and the non-wheel side of the wheel member is positioned below the housing case by inserting the 2B side of the wheel case into the insertion recess 11A at the bottom of the housing case 10A located at the lower stage. It becomes an adjuster for placing the storage case (see FIG. 8).
(3) Insert the wheel case 1B side of the wheel member 1 into the insertion recess 11B at the bottom of the housing case 10B located at the upper stage, and insert the recess at the ceiling of the housing case 10A located at the lower side of the wheel case 2A. By inserting it into 13A, it becomes a joint for connecting the upper and lower housing cases (see FIGS. 6 and 9). In this case, the wheel member may be upside down.
[0013]
12 to 14 are views showing an embodiment of the storage case of the present invention. In this embodiment, the wheel member 1 can be inserted in two different directions by forming the insertion recess 20A provided at the bottom into a cross shape. That is, if the wheel case 2 is inserted so that the rotation direction of the wheel of the wheel member matches the front-rear direction of the storage case 10A as shown in FIG. 13, the storage case can move in the front-rear direction, as shown in FIG. If the wheel case 2 is inserted so that the rotational direction of the wheel of the wheel member matches the left-right direction of the housing case 10A, the housing case can be moved in the left-right direction.
[0014]
【The invention's effect】
The present invention configured as described above has the following specific effects.
(1) Since the wheel can be attached to the storage case simply by inserting the wheel member incorporating the wheel into the insertion recess of the storage case, the customer can attach and detach the wheel to the storage case with a single touch if necessary.
(2) Since a locking projection protruding outward is provided on the middle circumferential side of the wheel case in the vertical direction, and the circumferential shape of the upper and lower wheel cases of this engagement projection is the same, the wheel member is reversed. When inserted into the insertion recess of the storage case, the non-wheel surface of the wheel member is positioned below the storage case, and the wheel member can be used as an adjuster for placing the storage case.
(3) Similarly, if the wheel member is inserted between the insertion recesses of the upper and lower storage cases, it can be used as a joint for coupling the upper and lower storage cases.
(4) As described above, since the wheel member can be used for multiple purposes, a plurality of members conventionally prepared according to each application are unified, and the manufacturing efficiency is rationalized, contributing to cost reduction. On the other hand, the consumer can freely recombine the combination and function of the storage case with one kind of member.
