Description

【０００１】
【発明の属する技術分野】
本発明は、各種の紙類を挟んで、磁性の壁面やホワイトボード等に磁着しておける磁石付きクリップに関する。
【０００２】
【従来の技術】
この種の従来のクリップとしては、下面側に磁石が取付けられた固定板と、該固定板の上面に回動自在に枢着され、ばねにより固定板の一方の端部側が常時閉塞されるようにした可動板とを備えたものがある（例えば特許文献１参照）。
【０００３】
【特許文献１】
特開平７−２９０８７２号公報（図１〜図６等）
【０００４】
【発明が解決しようとする課題】
上記特許文献１に記載されている従来のクリップでは、固定板の端縁を下方に直角に折曲することにより、矩形の収納空間を形成し、この収納空間に、比較的厚さの大きい磁石を収納して固定しているため、固定板の厚さが大となり、クリップ全体も厚型となっている。
また、磁石を接着剤を用いて固定しているため、それを塗布する工程が増えるとともに、長期間使用すると、接着剤が劣化して磁石が剥離する恐れがある。
【０００５】
本発明は、上記問題点を解決するためになされたもので、磁石が取付けられる台座の厚さを最小限として、クリップ全体の薄型化を図るとともに、接着剤やねじ等の固定手段を用いることなく、磁石を容易に固定しうるようにした磁石付きクリップ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】
上記目的を達成するために、本発明の磁石付きクリップは、磁石を有し、かつ下面が前記磁石により磁性金属板に吸着される平板状台座と、その上面に上下に回動可能に取付けられたレバー板と、前記台座とレバー板との前方の対向端を常時閉塞するように付勢する付勢手段とを備える磁石付きクリップにおいて、
前記台座に嵌合孔を穿設し、該嵌合孔内に、台座の板厚とほぼ等しい厚さの磁石を、抜け止め手段により台座の下方への脱落を防止して収容するとともに、前記レバー板の下面にレバー板の回動中心となる突部を突設し、該突部の下端面を、磁石の幅方向の上面に当接する円弧状の曲面として、前記嵌合孔内に磁石を保持したことを特徴としている。
上記構成の本発明によると、磁石は、台座の嵌合孔内収納されているため、台座の上下寸法はもとより、クリップ全体の薄型化が可能となる。
また、磁石は、抜け止め手段とレバー板の突部とにより、嵌合孔内に保持されているので、接着剤やねじ等の固定手段を用いる必要がない。しかもレバー板の円弧状の曲面により回動が支障なく円滑に行われるとともに、磁石の上面が均一かつ安定的に押圧される。
【０００８】
上記クリップにおいて、抜け止め手段を、嵌合孔の下面側の開口縁に内向き対向状に突設した少なくとも１対の係止突片とするのが好ましい。
このようにすると、別部材としての抜け止め手段を設けたりすることなく、嵌合孔に磁石を収容するだけで、簡単に下方への脱落が防止される。
【０００９】
上記クリップにおいて、嵌合孔を、磁石の外形形状と同じ形状に形成するのが好ましい。
このようにすると、嵌合孔内において磁石ががた付くのが防止される。
【００１０】
上記クリップにおいて、嵌合孔の上面側の開口縁の隅部に、１対の内向き保持片を突設するのが好ましい。
このようにすると、磁石が嵌合孔の上方に抜け出ることがないので、台座に予め磁石を組込んでおくことができ、組立工数が削減される。
【００１１】
上記クリップにおいて、台座とレバー板との対向面における回動中心部に、前方を向くとともに、後方が開口された凹部を形成し、双方の凹部内に、付勢手段としての側面視コ字状をなす板ばねの上下の前向片をそれぞれ嵌合することにより、台座とレバー板とを連結し、かつ板ばねの付勢力により、台座とレバー板との前方の対向端が常時閉塞されるようにするのが好ましい。
このようにすると、コ字状の板ばねは、台座とレバー板との連結部材も兼ねているので、部品点数が削減されるとともに、台座とレバー板との連結部の構造が簡単となる。
【００１２】
上記クリップにおいて、レバー板の左右両側部下面に、板ばねの外側端を覆いうる大きさのカバー片を下向きに突設するのが好ましい。
このようにすると、板ばねが側方より見えなくなるので、クリップの見栄えが向上する。
【００１３】
上記クリップにおいて、台座とレバー板との回動中心における対向面に、レバー板の回動を許容可能として互いに係合し合う突部と凹部を設けるのが好ましい。
このようにすると、台座とレバー板との位置決めが容易となるとともに、回動中心である互いの当接面が位置ずれするのが防止される。
【００１４】
上記クリップにおいて、台座におけるカバー板の回動中心よりも前方の上面に、紙類の端面が当接するストッパー部を上向きに突設するのが好ましい。
このようにすると、紙類を重ねて挟む際に、端面を揃えて挟持することができる。
【００１５】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて説明する。
【００１６】
図１は、本発明の磁石付きクリップの側面図、図２は同じく中央縦断側面図、図３は分解斜視図である。
【００１７】
本発明の磁石付きクリップは、平面視ほぼ矩形平板状をなす合成樹脂製の台座１と、それよりも若干小形の合成樹脂製のレバー板２と、鉄製ヨーク３の下面に固着された矩形の薄形磁石４と、側面視コ字状の１対の板ばね５，５とからなっている。
【００１８】
台座１の後方寄り（以下、図１の左方を前として説明する。）の中央部には、上下寸法が台座１の厚さとほぼ等しい下向きコ字状のヨーク３が収容される、それと同形の矩形をなす嵌合孔６が穿設されている。
【００１９】
嵌合孔６の下方の開口縁には、前後１対の係止突片７，７が、内向き対向状に一体的に形成され、両係止突片７には、上記磁石４の前後両端部下面が受支されて、嵌合孔６の下方への脱落が防止されるようになっている。

【００２１】
なお、嵌合孔６内に磁石４を有するヨーク３を収容した際、ヨーク３の左右の下端面が、台座１の下面と同一面に整合するか、又は台座１の下面より若干上方に位置するようになっている。
【００２２】
台座１における嵌合孔６を挟む上面には、左右１対の上向き膨出部９，９が形成され、その平坦面をなす前後方向の中間部上面には、突部１０と凹部１１とが形成されている。
【００２３】
また、両膨出部９の後半部の傾斜面には、上記板ばね５の下方の前向片５ａが挿入可能な開口部１２が形成され、この開口部１２は、図５に示すように、膨出部９の前半部下方に形成された、下方が開口する凹部１３と連通している。
【００２４】
左右の膨出部９の前端面は、垂直をなすストッパー面１４とされ、図６に示すように、複数枚の紙類Ｐを挿入した際、その端面が当接することにより、端面同士を揃えて挟むことができるようになっている。
【００２５】
レバー板２の前端部には、台座１の前端部上面と面接触しうるように下向き円弧状の折曲部２ａが形成されている。
なお、折曲部２ａの下端面に、滑り止め用の凹凸条を設けたり、ゴム材等を貼着してもよい。
【００２６】
図４の底面斜視図にも示すように、レバー板２の回動中心である下面のほぼ中央部には、下面（図４では上面）が円弧状の曲面をなす突部１５が、左右方向を向いて突設されている。
【００２７】
上記突部１５の左右寸法は、ヨーク３の左右寸法とほぼ等しい寸法とされ、図２に示すように、台座１にレバー板２を組付けた際、突部１５の下端は、ヨーク３における前後方向の中間部上面に当接するようになっている。
【００２８】
レバー板２の下面における突部１５を挟む両側には、前後方向の中間部が下向き山形状をなす左右１対の下向き膨出部１６、１６が形成され、その回動中心となる最下端面には、上記台座１の突部１０と凹部１１とに係合される突部１０と凹部１１が形成されている。なお、レバー板２を支障なく回動させうるように、凹部１１の大きさを突部１０の径よりも若干大としている。
【００２９】
両膨出部１６における後半部には、上記板ばね５の上方の前向片５ａが挿入可能な開口部１７が形成され、この開口部１７は、図５に示すように、膨出部１６の前半部上方に形成された凹部１８と連通している。
【００３０】
レバー板２における膨出部１６の外側方の下面には、板ばね５を取付けた際に、その側端を覆いうる大きさのカバー片１９が下向きに突設されている。
【００３１】
次に、上記実施形態のクリップの組立て要領を説明する。
まず台座１の嵌合孔６内に、予め磁石４を固着してなるヨーク３を上方より収容する。
【００３２】
次いで、台座１の上向き膨出部９と、レバー板２の下向き膨出部１６との対向面に設けた突部１０と凹部１１とを互いに係合させるようにして、台座１の上面にレバー板２を載置する。
【００３３】
次いで、台座１とレバー板２の膨出部９、１６に形成した開口部１２、１７より、板ばね５を挿入し、その上下の前向片５ａを、それぞれ台座１とレバー板２の凹部１３、１８内に押し込む。
【００３４】
この際、上下の前向片５ａが上下方向に互いに反対向きに弾性変形されることにより、台座１とレバー板２との膨出部９、１６の対向面同士が強く当接して互いに連結され、かつ両前向片５ａの前端が回動中心よりも前方を押圧することにより、レバー板２の前端が台座１の上面と当接して閉塞状態に保持される（図５参照）。
【００３５】
なお、板ばね５が上下の凹部１３、１８から抜け出るのを防止するために、上下の前向片５ａの前端部に内向き円弧状の係止突条５ｂ、５ｂを形成し、両係止突条５ｂを、台座１の膨出部９の下面と、レバー板２の膨出部１６の上面とに形成した係合溝２０に、それぞれ係合させるようにするのがよい。
【００３６】
紙類Ｐを挟持する際は、レバー板２の後端部を、板ばね５の付勢力に抗して下向きに押圧して回動させ、前端を台座１に対して開けばよい。
【００３７】
また、台座１の下面を磁性の壁面やホワイトボード等に当接させると、磁石４とヨーク３の磁着力により、紙類Ｐを挟んだ状態でクリップを吸着しておくことができる。
【００３８】
以上説明したように、上記実施形態の磁石付きクリップにおいては、台座１に嵌合孔６を設け、この嵌合孔６内に、台座１の板厚とほぼ等しい上下寸法の、磁石４と一体をなすヨーク３を収容しているため、台座１の上下寸法はもとより、クリップ全体を薄型化することができる。
【００３９】
また、ヨーク３及び磁石４は、係止突片７により下方への脱落が阻止され、かつ上面がレバー板２の下面の突部１５により押えられているため、接着剤やねじ等の固定手段を用いる必要はなく、組立て工数や部品点数を削減することができる。
【００４０】
なお、上記実施形態では、台座１の中央部に磁石４を配置し、それを挟む両側にレバー板２の支点を有するようにしているが、その反対に、台座１の中央部をレバー板２の支点とし、それを挟む両側に１対の嵌合孔６を形成して、その中に磁石４を嵌合するようにしてもよい。
【００４１】

BACKGROUND OF THE INVENTION
The present invention relates to a clip with a magnet that can be magnetically attached to a magnetic wall surface, a whiteboard or the like with various papers interposed therebetween.
[0002]
[Prior art]
In this type of conventional clip, a fixed plate having a magnet attached to the lower surface side, and pivotally attached to the upper surface of the fixed plate so that one end side of the fixed plate is always closed by a spring. There is a thing provided with the movable plate made into (for example, refer to patent documents 1).
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 7-290872 (FIGS. 1 to 6 etc.)
[0004]
[Problems to be solved by the invention]
In the conventional clip described in Patent Document 1, a rectangular storage space is formed by bending the edge of the fixing plate at a right angle downward, and a relatively thick magnet is formed in this storage space. Since the container is stored and fixed, the thickness of the fixing plate is large, and the entire clip is also thick.
In addition, since the magnet is fixed using an adhesive, the number of steps for applying the magnet increases, and when used for a long period of time, the adhesive may deteriorate and the magnet may peel off.
[0005]
The present invention has been made in order to solve the above-described problems. The thickness of the pedestal to which the magnet is attached is minimized, the entire clip is thinned, and a fixing means such as an adhesive or a screw is used. It aims at providing the clip with a magnet which enabled it to fix a magnet easily.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a clip with a magnet according to the present invention is provided with a flat base that has a magnet and whose lower surface is attracted to the magnetic metal plate by the magnet, and is attached to the upper surface so as to be vertically rotatable. A clip with a magnet comprising: a lever plate; and a biasing means that biases the front and opposite ends of the pedestal and the lever plate at all times.
A fitting hole is formed in the pedestal, and a magnet having a thickness substantially equal to the plate thickness of the pedestal is accommodated in the fitting hole while preventing the pedestal from falling off by the retaining means, and A protrusion that serves as the center of rotation of the lever plate protrudes from the lower surface of the lever plate, and the lower end surface of the protrusion is an arcuate curved surface that contacts the upper surface in the width direction of the magnet. It is characterized by holding.
According to the present invention having the above configuration, since the magnet is housed in the fitting hole of the pedestal, the entire clip can be thinned in addition to the vertical dimension of the pedestal.
Further, since the magnet is held in the fitting hole by the retaining means and the protrusion of the lever plate, it is not necessary to use fixing means such as an adhesive or a screw. In addition, the arcuate curved surface of the lever plate allows smooth rotation without hindrance, and the upper surface of the magnet is pressed uniformly and stably.
[0008]
In the above clip, it is preferable that the retaining means is at least one pair of locking projections projecting inwardly facing the opening edge on the lower surface side of the fitting hole.
If it does in this way, falling off will be easily prevented only by accommodating a magnet in a fitting hole, without providing a retaining means as another member.
[0009]
In the clip, the fitting hole is preferably formed in the same shape as the outer shape of the magnet.
This prevents the magnet from rattling in the fitting hole.
[0010]
In the above clip, it is preferable that a pair of inward holding pieces protrude from the corner of the opening edge on the upper surface side of the fitting hole.
If it does in this way, since a magnet does not slip out above a fitting hole, a magnet can be beforehand built into a base and an assembly man-hour is reduced.
[0011]
In the above clip, a concave portion that is directed forward and opened at the rear is formed at the center of rotation of the opposed surface of the base and the lever plate, and a U-shape in a side view as a biasing means is formed in both concave portions. The plate spring and the lever plate are connected to each other by fitting the upper and lower forward pieces of the plate spring, and the urging force of the plate spring always closes the front facing end of the plate spring and the lever plate. It is preferable to do so.
In this way, the U-shaped leaf spring also serves as a connecting member between the base and the lever plate, so that the number of parts is reduced and the structure of the connecting portion between the base and the lever plate is simplified.
[0012]
In the above clip, it is preferable that a cover piece having a size capable of covering the outer end of the leaf spring is protruded downward on the lower surfaces of the left and right side portions of the lever plate.
If it does in this way, since a leaf | plate spring will become invisible from the side, the appearance of a clip will improve.
[0013]
In the above clip, it is preferable to provide a projecting portion and a recessed portion that engage with each other so that the lever plate is allowed to rotate on the opposing surface at the center of rotation between the base and the lever plate.
If it does in this way, positioning with a base and a lever board will become easy, and it will prevent that the mutual contact surface which is a rotation center shifts | deviates.
[0014]
In the above clip, it is preferable that a stopper portion with which the end face of the paper comes into contact with the upper surface in front of the rotation center of the cover plate in the base protrudes upward.
If it does in this way, when papers are stacked and pinched, it can be pinched by aligning an end face.
[0015]
