しかし、特許文献1に記載の掲示具においては、磁石は掲示板とは別体として設けられているため、掲示物の取付作業中に磁石が落下したり、磁石が失われたりすることがあり、作業効率が悪いという問題がある。 However, in the bulletin board described in Patent Document 1, since the magnet is provided separately from the bulletin board, the magnet may fall or be lost during the installation work of the bulletin board. There is a problem of poor work efficiency.

本発明は、上記した課題に着目してなされたものであり、磁石が掲示板から外れず、掲示物の着脱作業効率が良い掲示具を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a bulletin board in which the magnet does not come off the bulletin board and the work of attaching and removing the bulletin board is efficient.

本発明による掲示具は、掲示物を止めるための掲示面を備え、前記掲示面の少なくとも一部は磁性材料からなる取付面である掲示部材と、前記磁性材料と引き合う磁石を有し、前記掲示面との間に掲示物を挟んで止めるための留め具と、前記留め具を前記掲示部材に連結し、前記留め具を前記掲示部材から離れる方向に付勢する弾性部材とを備える。 A bulletin board according to the present invention includes a bulletin board surface for stopping a bulletin board, a bulletin board member in which at least a part of the bulletin board surface is a mounting surface made of a magnetic material, and a magnet that attracts the magnetic material; The display device includes a fastener for sandwiching and fixing a notice between the surfaces, and an elastic member that connects the fastener to the notice member and urges the fastener in a direction away from the notice member.

上記の構成によれば、磁石を備える留め具が弾性部材により掲示部材と連結されているため、掲示物を掲示具に止める際に、留め具が落下したり留め具が失われたりすることがなく、着脱作業効率が良い。 According to the above configuration, since the clasp including the magnet is connected to the bulletin board member by the elastic member, there is no possibility that the clasp will fall or be lost when securing the bulletin board to the bulletin board. Easy to attach and detach.

また、弾性部材により留め具は掲示部材から離れる方向に付勢されているため、作業者が留め具を掲示面に近づけていくと、ある位置で磁石と掲示面との間の吸引力が弾性部材による付勢力に勝り、作業者が力を加えなくても吸引力により留め具が掲示面に吸着する。また、作業者が留め具を掲示部材から離していくと、ある位置で弾性部材の付勢力が磁石と掲示面との間の吸引力に勝り、作業者が力を加えなくても付勢力により留め具は掲示部材から離れる。留め具は、留め具の重量や弾性部材の付勢力に応じた位置で弾性部材に支持される。 In addition, since the elastic member biases the fastener in the direction away from the bulletin board member, as the worker approaches the fastener to the bulletin board surface, the attractive force between the magnet and the bulletin board at a certain position becomes elastic. The fastener is attracted to the bulletin board by the suction force, which overcomes the biasing force of the member and requires no force from the operator. Additionally, as the worker moves the fastener away from the bulletin board member, the biasing force of the elastic member will overcome the attractive force between the magnet and the bulletin board surface at a certain position, and the biasing force will increase even if the worker does not apply any force. The fastener separates from the bulletin board member. The fastener is supported by the elastic member at a position corresponding to the weight of the fastener and the biasing force of the elastic member.

このように、作業者は最初に留め具に力を加えて留め具を掲示面に近づける動作、離す動作を行うと、ある位置からは作業者が力を加えなくても留め具は磁石と掲示面との間の吸引力により吸着し、また、弾性部材の付勢力に掲示面から離れていくため、作業者に余分な力が不要であり、作業が楽である。 In this way, if the worker first applies force to the clasp and moves the clasp closer to the bulletin board and then moves it away from the bulletin board, the clasp will become a magnet and the bulletin board from a certain position without the worker applying any force. Since the bulletin board is attracted by the suction force between the bulletin board and the bulletin board surface, and is moved away from the bulletin board by the biasing force of the elastic member, the operator does not need to apply any extra force, making the work easier.

好ましい実施形態においては、前記磁石にヨークが取付けられており、前記ヨークの端部は前記磁石の端面よりも突出しており、前記ヨークの端部が前記取付面と掲示物を介して接触する。 In a preferred embodiment, a yoke is attached to the magnet, an end of the yoke protrudes beyond an end surface of the magnet, and the end of the yoke contacts the mounting surface via a bulletin board.

好ましい実施形態においては、弾性部材は板バネである。 In a preferred embodiment, the elastic member is a leaf spring.

好ましい実施形態においては、前記留め具は、前記磁石を収容する本体部を備え、前記本体部には、作業者が前記留め具に指を掛けるための係止部が設けられている。 In a preferred embodiment, the fastener includes a main body portion that accommodates the magnet, and the main body portion is provided with a locking portion for an operator to hook his/her finger onto the fastener.

棒状部材からなる前記掲示部材と、複数の前記留め具と、前記各留め具をそれぞれ前記掲示部材に連結する複数の前記弾性部材とを備え、前記複数の留め具は所定の間隔で前記掲示部材の長さ方向に配置されている。 The bulletin board member is made of a rod-shaped member, a plurality of the fasteners, and a plurality of elastic members that respectively connect the fasteners to the bulletin board member, and the plurality of fasteners are connected to the bulletin board member at predetermined intervals. are arranged along the length of the

本発明による掲示装置は、上記のいずれかに記載の掲示具と、前記掲示具を昇降させる昇降機構とを有する。 A bulletin board device according to the present invention includes any one of the bulletin boards described above and a lifting mechanism that raises and lowers the bulletin board.

本発明によれば、磁石を備える留め具が弾性部材により掲示部材と連結されているため、掲示物を掲示具に止める際に、留め具が落下したり留め具が失われたりすることがなく、着脱作業効率が良い。 According to the present invention, since the clasp including the magnet is connected to the bulletin board member by the elastic member, the clasp will not fall or be lost when the bulletin board is attached to the bulletin board. , good efficiency in attaching and detaching work.

本発明の実施形態を図面を参照して説明する。図1は本発明の一実施形態を示しており、本発明の掲示具10が用いられる掲示装置1を示す。掲示装置1は、例えば体育館、ホールの舞台に設けられ、観衆に、ポスターや看板などの掲示物Pを掲示するものである。掲示装置1は、掲示具10と、掲示具10を昇降させる昇降機構2とを備える。 Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows one embodiment of the present invention, and shows a bulletin board device 1 in which a bulletin board 10 of the present invention is used. The bulletin board device 1 is installed, for example, on a stage in a gymnasium or hall, and displays bulletin materials P such as posters and signboards to the audience. The bulletin board device 1 includes a bulletin board 10 and a lifting mechanism 2 that raises and lowers the bulletin board 10.

昇降機構2は、舞台の天井に設けられており、ボックスケース3内に、長尺のシャフト4と、シャフト4の一端部に設けられシャフト4を回転させるモータ5と、シャフト4の両端及び両端の間の所定の複数箇所に設けられた複数のワイヤー巻取プーリー6とを備えている。ワイヤー巻取プーリー6に巻かれたワイヤー7の先端には、掲示具10が水平となるように取付けられている。モータ5によりシャフト4を正逆方向に回転させることで、ワイヤー巻取プーリー6がワイヤー7を巻き取って掲示具10を上昇させ、ワイヤー巻取プーリー6がワイヤー7を繰り出して掲示具10を下降させる。これにより、掲示具10の高さを調整する。なお、昇降機構2は本実施形態に限定されず、掲示具10を昇降させることができれば、例えば、ウインチやリニアモータ等により構成してもよい。 The elevating mechanism 2 is installed on the ceiling of the stage, and inside the box case 3 includes a long shaft 4, a motor 5 installed at one end of the shaft 4 to rotate the shaft 4, and both ends of the shaft 4. A plurality of wire winding pulleys 6 are provided at a plurality of predetermined locations between the two. A bulletin board 10 is attached horizontally to the tip of the wire 7 wound around the wire take-up pulley 6. By rotating the shaft 4 in the forward and reverse directions by the motor 5, the wire take-up pulley 6 winds up the wire 7 and raises the sign 10, and the wire take-up pulley 6 lets out the wire 7 and lowers the sign 10. let Thereby, the height of the bulletin board 10 is adjusted. Note that the elevating mechanism 2 is not limited to this embodiment, and may be configured by, for example, a winch, a linear motor, or the like, as long as it can raise and lower the bulletin board 10.

掲示装置1を使用するには、まず、昇降機構2のモータ5を動作させて、掲示具10を作業者が作業しやすい高さに位置させる。作業者により掲示具10に掲示物Pを固定した後、再びモータ5を動作させて掲示具10を上昇させて所定の高さに位置させることで、掲示具10に掲示物Pが吊り下げられる。 To use the bulletin board device 1, first, the motor 5 of the lifting mechanism 2 is operated to position the bulletin board 10 at a height that is convenient for the operator to work with. After the worker fixes the bulletin board P to the bulletin board 10, the motor 5 is operated again to raise the bulletin board 10 and position it at a predetermined height, thereby suspending the bulletin board P from the bulletin board 10. .

なお、掲示装置1は掲示具10を備えていればいずれの形態でもよく、例えば、昇降機構2を設けず、シャフト4にワイヤー7で掲示具10を吊り下げた構成であって掲示具10が昇降しない掲示装置1であってもよい。 Note that the bulletin board device 1 may have any form as long as it is equipped with the bulletin board 10. For example, the bulletin board device 1 may have a configuration in which the lifting mechanism 2 is not provided and the bulletin board 10 is suspended from the shaft 4 by a wire 7, and the bulletin board 10 is The bulletin board device 1 may not be raised or lowered.

次に、掲示具10の詳細について説明する。掲示具10は、磁性材料から構成される取付面22を有する掲示部材20と、磁石31を有する留め具30と、留め具30と掲示部材20とを連結する弾性部材である板バネ11とを備えており、留め具30と掲示部材20の取付面22との間に吸引力を作用させて留め具30と掲示部材20との間に掲示物Pを留めるものである。なお、以下の説明では、留め具30が掲示部材20から離れる方向(図7に示す矢印Aの方向)を「開方向」といい、留め具30に掲示面21に近づく方向(矢印Aと反対の方向)を「閉方向」という。 Next, details of the bulletin board 10 will be explained. The bulletin board 10 includes a bulletin board member 20 having a mounting surface 22 made of a magnetic material, a fastener 30 having a magnet 31, and a leaf spring 11 that is an elastic member that connects the fastener 30 and the bulletin board member 20. A suction force is applied between the fastener 30 and the mounting surface 22 of the notice member 20 to fix the notice P between the fastener 30 and the notice member 20. In the following explanation, the direction in which the fastener 30 moves away from the bulletin board member 20 (the direction of arrow A shown in FIG. ) is called the "close direction".

掲示部材20は1本の棒状部材からなり、複数の留め具30が所定の間隔で掲示部材20の長さ方向に配置されている。掲示部材20は、図3、図4に示すように、断面が縦長の長方形の筒状の棒状部材であり、外周面のうちの一方の側面は、掲示物Pを挟んで止めるための掲示面21である。本実施形態においては、掲示部材20は、その全体が例えば鉄、ニッケル、コバルト、フェライト等の磁性材料から構成されており、掲示面21全体が磁石31との間で吸引力が発生する取付面22となっている。また、掲示部材20の上面23には、板バネ11を取付けるためのネジ孔24が形成されている。なお、以下の説明では、図2において留め具30が取付けられる掲示面21側を正面側または前側として説明する。留め具30は、掲示具10が舞台の天井から降下した時に、客席側から見えないように、掲示部材20の客席側とは反対側の面に設けられる。 The bulletin board member 20 is made of one rod-shaped member, and a plurality of fasteners 30 are arranged at predetermined intervals in the length direction of the bulletin board member 20. As shown in FIGS. 3 and 4, the bulletin board member 20 is a cylindrical bar member with a vertically elongated rectangular cross section, and one side of the outer peripheral surface is a bulletin board surface for sandwiching and stopping the bulletin board P. It is 21. In this embodiment, the entire bulletin board member 20 is made of a magnetic material such as iron, nickel, cobalt, ferrite, etc., and the entire bulletin board surface 21 is a mounting surface where an attractive force is generated between the bulletin board member 20 and the magnet 31. It is 22. Further, a screw hole 24 for attaching the leaf spring 11 is formed in the upper surface 23 of the bulletin board member 20. In the following description, the side of the bulletin board 21 to which the fastener 30 is attached in FIG. 2 will be referred to as the front side or front side. The fastener 30 is provided on the surface of the bulletin board member 20 opposite to the audience seat side so that it cannot be seen from the audience seat side when the bulletin board 10 is lowered from the ceiling of the stage.

なお、掲示部材20の形状は本実施形態には限定されず、例えば、断面形状が略正方形であってもよく、多角形であってもよい。また、掲示部材20を非磁性材料により構成し、掲示面21のうちの少なくとも一部、すなわち、留め具30の磁石31に対応する領域を磁性材料により構成して取付面22としてもよい。さらに、掲示部材20は2本以上の棒状部材から構成され、棒状部材が長さ方向に配置されたものであってもよい。この場合、各棒状部材毎にワイヤー7が取付けられる。 Note that the shape of the bulletin board member 20 is not limited to this embodiment, and for example, the cross-sectional shape may be approximately square or polygonal. Alternatively, the bulletin board member 20 may be made of a non-magnetic material, and at least a portion of the bulletin board surface 21, that is, a region corresponding to the magnet 31 of the fastener 30, may be made of a magnetic material to serve as the mounting surface 22. Furthermore, the bulletin board member 20 may be composed of two or more rod-shaped members, and the rod-shaped members may be arranged in the length direction. In this case, the wire 7 is attached to each rod-shaped member.

本実施形態では、掲示部材20の下面には、掲示部材20と略同じ長さのピクチャーレール12がネジ止めされており、ピクチャーレール12にワイヤーが付いたフックを係止して絵などの掲示物Pが取付けられるようになっている。なお、ピクチャーレール12の取付は任意である。 In this embodiment, a picture rail 12 having approximately the same length as the bulletin board member 20 is screwed to the bottom surface of the bulletin board member 20, and a hook with a wire attached to the picture rail 12 is locked to display a bulletin board such as a picture. Object P can be attached. Note that attachment of the picture rail 12 is optional.

留め具30は、磁石31と、磁石31が埋め込まれる本体部40とを備えている。磁石31は、図6に示すように直方体に形成されており、磁石31にはヨーク32が取付けられている。ヨーク32は継鉄とも呼ばれ、珪素鉄やステンレス鋼である軟質磁性材料からなる。ヨーク32は、底壁32A及び両側壁32B、32Bを有する断面コ字形状に形成されている。底壁32Aの2箇所にネジ孔32aが貫通して設けられており、ネジ孔32aには、本体部40にヨーク32を固定するための皿ネジ33が通され、図3に示すように、ネジ孔32aは皿ネジ33の頭部33aに対応する形状となっている。なお、ネジ孔32aの個数やネジの種類は本実施形態に限定されない。磁石31は、その正面31a、上面31b、下面31cに、それぞれ、ヨーク32の底壁32A及び両側壁32B、32Bが接触するように、ヨーク32の内部に接着剤等の接着手段で固定される。ヨーク32の両側壁32B、32Bの高さは磁石31の高さよりも高く設定されているため、図3、図4、図6に示すように、ヨーク32の両側壁32B、32Bの先端部32b、32bは磁石31の背面31d(端面)よりも後側に突出している。図3、図4に示すように、ヨーク32の先端部32b、32bが取付面22と掲示物Pを介して接触することで、留め具30により掲示物Pを掲示面21に固定した状態とすることが可能になる。このようにヨーク32を設けることで、ヨーク32は、磁石31とともに磁気回路を構成し、ヨーク32の先端部32b、32bにおいて吸引力が発生し、ヨーク32を用いない場合に比べて留め具30の吸引力が向上する。なお、ヨーク32は、底壁32Aと4つの側壁を有する形状としてもよく、4つの側壁の先端部が磁石31の背面31dよりも後側に突出していてもよい。 The fastener 30 includes a magnet 31 and a main body portion 40 in which the magnet 31 is embedded. The magnet 31 is formed into a rectangular parallelepiped, as shown in FIG. 6, and a yoke 32 is attached to the magnet 31. The yoke 32 is also called a yoke and is made of a soft magnetic material such as silicon iron or stainless steel. The yoke 32 has a U-shaped cross section and has a bottom wall 32A and side walls 32B, 32B. Screw holes 32a are provided penetrating the bottom wall 32A at two locations, and countersunk screws 33 for fixing the yoke 32 to the main body portion 40 are passed through the screw holes 32a, as shown in FIG. The screw hole 32a has a shape corresponding to the head 33a of the countersunk screw 33. Note that the number of screw holes 32a and the types of screws are not limited to those in this embodiment. The magnet 31 is fixed inside the yoke 32 by adhesive means such as adhesive so that the front surface 31a, upper surface 31b, and lower surface 31c are in contact with the bottom wall 32A and both side walls 32B, 32B of the yoke 32, respectively. . Since the heights of the side walls 32B, 32B of the yoke 32 are set higher than the height of the magnet 31, the tips 32b of the side walls 32B, 32B of the yoke 32, as shown in FIGS. , 32b protrude rearward from the back surface 31d (end surface) of the magnet 31. As shown in FIGS. 3 and 4, the tips 32b, 32b of the yoke 32 come into contact with the mounting surface 22 through the bulletin board P, thereby fixing the bulletin board P to the bulletin board surface 21 by the fastener 30. It becomes possible to do so. By providing the yoke 32 in this way, the yoke 32 constitutes a magnetic circuit together with the magnet 31, and an attractive force is generated at the tip portions 32b, 32b of the yoke 32. The suction power is improved. The yoke 32 may have a bottom wall 32A and four side walls, and the tips of the four side walls may protrude rearward from the back surface 31d of the magnet 31.

本体部40は、例えば合成樹脂から構成されており、磁石31が埋め込まれる第1の部材41と、第1の部材41の正面41d側に設けられる板状の第2の部材45と、第2の部材45の正面側に設けられる第3の部材46とから構成されている。なお、本体部40は合成樹脂に限らず例えばアルミニウムなどの金属素材から構成されていてもよい。 The main body part 40 is made of, for example, synthetic resin, and includes a first member 41 in which the magnet 31 is embedded, a plate-shaped second member 45 provided on the front surface 41d side of the first member 41, and a second member 45. The third member 46 is provided on the front side of the member 45. Note that the main body portion 40 is not limited to synthetic resin, and may be made of a metal material such as aluminum.

図5は留め具30の背面図であり、第1の部材41は二つの等しい長さの平行線と二つの略半円形により囲まれる角円長方形状であって、長さ方向の両端部は面取りされた第1の丸み部41a、41aとなっている。図2、図3に示すように、第1の部材41の掲示部材20の掲示面21と対向する背面41bには凹部42が形成され、凹部42には長さ方向の両端側の2箇所にヨーク32を取付けた磁石31が収容されている。 FIG. 5 is a rear view of the fastener 30, and the first member 41 has a square rectangular shape surrounded by two parallel lines of equal length and two approximately semicircles, and both ends in the length direction are The first rounded portions 41a, 41a are chamfered. As shown in FIGS. 2 and 3, a recess 42 is formed in the back surface 41b of the first member 41 facing the bulletin board surface 21 of the bulletin board 20, and the recess 42 has two locations on both ends in the length direction. A magnet 31 with a yoke 32 attached thereto is housed.

図3に示すように、凹部42にヨーク32を取付けた磁石31が収容された状態で、凹部42の底部においてヨーク32の底壁32Aのネジ孔32aに対応する位置にネジ溝が設けられたネジ孔41cが貫通している。凹部42にヨーク32及び磁石31を収容するには、まず、凹部42にヨーク32を皿ネジ33で留める。このとき、皿ネジ33の頭部33aはヨーク32のネジ孔32a内に収容され、皿ネジ33のネジ部は第1の部材41のネジ孔41cと螺合する。そして、磁石31を接着剤等の接着手段によりヨーク32の底壁32A及び両側壁32B、32Bに固定する。なお、ヨーク32の本体部40への固定は皿ネジ33に限らず、ヨーク32が本体部40へ固定できればいずれの手段を用いてもよく、例えば、接着剤等の接着手段を用いても良い。また、磁石31のヨーク32への固定も接着剤等の接着手段に限定されず、磁石31がヨーク32へ固定できればいずれの手段を用いても良い。また、ヨーク32を用いずに磁石31が直接凹部42に嵌め込まれて固定されていてもよい。 As shown in FIG. 3, when the magnet 31 with the yoke 32 attached is accommodated in the recess 42, a screw groove is provided at the bottom of the recess 42 at a position corresponding to the screw hole 32a of the bottom wall 32A of the yoke 32. A screw hole 41c passes through it. In order to accommodate the yoke 32 and the magnet 31 in the recess 42 , first, the yoke 32 is fastened to the recess 42 with flat head screws 33 . At this time, the head 33a of the countersunk screw 33 is accommodated in the screw hole 32a of the yoke 32, and the threaded portion of the countersunk screw 33 is screwed into the screw hole 41c of the first member 41. Then, the magnet 31 is fixed to the bottom wall 32A and both side walls 32B, 32B of the yoke 32 by adhesive means or the like. Note that fixing the yoke 32 to the main body part 40 is not limited to the countersunk screw 33, and any means may be used as long as the yoke 32 can be fixed to the main body part 40. For example, adhesive means such as adhesive may be used. . Furthermore, fixing the magnet 31 to the yoke 32 is not limited to adhesive means such as adhesive, and any means may be used as long as the magnet 31 can be fixed to the yoke 32. Alternatively, the magnet 31 may be directly fitted into the recess 42 and fixed without using the yoke 32.

図3、図4に示すように、第1の部材41の正面41dには、弾性部材を構成する板バネ11を取付けるためのネジ穴43bが形成されている。ネジ穴43bは、図2における横方向において、2箇所に設けられたネジ孔41cの間の中央に位置する。第1の部材41の正面41d側の上端部は、角部が面取りされた第2の丸み部43aとなっている。 As shown in FIGS. 3 and 4, a screw hole 43b is formed in the front surface 41d of the first member 41 to attach the leaf spring 11 constituting the elastic member. The screw hole 43b is located at the center between the two screw holes 41c in the lateral direction in FIG. 2. The upper end portion of the first member 41 on the front side 41d is a second rounded portion 43a with chamfered corners.

板バネ11は、矩形状の平板状のバネであり、長さ方向の両端部にネジ孔が形成されている。板バネ11の一端部は、第1の部材41の正面42d上の上端部に配置され、ネジ穴43bと板バネ11のネジ孔とにネジ13を螺合することで留め具30に固定されている。板バネ11の他端部は、板バネ11のネジ孔と掲示部材20の上面23に形成されたネジ孔24にネジ14を螺合することで固定されている。この板バネ11により、留め具30を掲示部材20から離れる方向(開方向)に付勢している。本実施形態では、留め具30の開閉時に板バネ11は第2の丸み部43aに沿うため、留め具30に第2の丸み部43aを設けず角部を残した状態と比べて、板バネ11が角部に当たることなく留め具30の開閉がスムーズに行われる。なお、板バネ11は、ネジにより第1の部材41と掲示部材20に固定されているが、ネジに限定されず、例えば溶接でもよく、板バネ11を第1の部材41と掲示部材20に固定することができればいずれの手段を用いても良い。 The leaf spring 11 is a rectangular flat spring, and screw holes are formed at both ends in the length direction. One end of the leaf spring 11 is arranged at the upper end on the front surface 42d of the first member 41, and is fixed to the fastener 30 by screwing the screw 13 into the screw hole 43b and the screw hole of the leaf spring 11. ing. The other end of the leaf spring 11 is fixed by screwing a screw 14 into a screw hole of the leaf spring 11 and a screw hole 24 formed in the upper surface 23 of the bulletin board member 20. This plate spring 11 urges the fastener 30 in a direction away from the bulletin board member 20 (opening direction). In this embodiment, since the leaf spring 11 follows the second rounded part 43a when the fastener 30 is opened and closed, the leaf spring 11 is more flexible than a state in which the second rounded part 43a is not provided on the fastener 30 and the corner part is left. The fastener 30 can be opened and closed smoothly without the clasp 11 hitting the corner. Note that the leaf spring 11 is fixed to the first member 41 and the bulletin board member 20 with screws, but is not limited to screws, and may be, for example, welded. Any means may be used as long as it can be fixed.

なお、弾性部材は板バネ11に限定されず、留め具30を掲示部材20から離れる方向に付勢できるものであればよく、例えば、スプリングを有する蝶番であってもよい。 Note that the elastic member is not limited to the leaf spring 11, and may be any member that can bias the fastener 30 in a direction away from the bulletin board member 20. For example, it may be a hinge having a spring.

第1の部材41の正面41dには、第2の部材45が接着剤等の接着手段により取付けられている。第2の部材45は、第1の部材41の正面41dにネジ13で止められた板バネ11の上にも被さるが、板バネ11の厚みは十分に小さいため、第2の部材45の取付けに影響を与えない。第2の部材45は、略矩形状の平板部材であって、第1の部材41よりも一回り大きく形成されており、第2の部材45の第1の部材41からはみ出た部分は作業者が指を引っ掛ける係止部45aを構成する。また、第2の部材45により、第1の部材41の正面41dに現われるヨーク32を取付けるためのネジ孔41cや、板バネ11を取付けるためのネジ穴43b及びネジ13を隠している。図4に示すように、第2の部材45の背面であって、第1の部材41の板バネ11を固定するネジ穴に対応する位置には、ネジ13のネジ頭を収容するための窪み部45bが形成されている。 A second member 45 is attached to the front surface 41d of the first member 41 by adhesive means such as adhesive. The second member 45 also covers the leaf spring 11 fixed to the front face 41d of the first member 41 with the screw 13, but since the thickness of the leaf spring 11 is sufficiently small, the attachment of the second member 45 is difficult. does not affect. The second member 45 is a substantially rectangular flat plate member and is formed to be one size larger than the first member 41, and the portion of the second member 45 that protrudes from the first member 41 is constitutes a locking portion 45a on which a finger is hooked. Further, the second member 45 hides a screw hole 41c for attaching the yoke 32 appearing on the front surface 41d of the first member 41, a screw hole 43b for attaching the leaf spring 11, and the screw 13. As shown in FIG. 4, on the back surface of the second member 45, a recess for accommodating the screw head of the screw 13 is provided at a position corresponding to the screw hole for fixing the leaf spring 11 of the first member 41. A portion 45b is formed.

第2の部材45の正面には、第3の部材46が接着剤等の接着手段で固定されている。第3の部材46は、第2の部材45よりも一回り小さく形成され、第2の部材45よりも厚みが大きく、第1の部材41よりも厚みが小さく設定されている。第3の部材46は作業者が指を引っ掛ける係止部を構成し、第3の部材46の下面や上面に作業者が指を掛けて留め具30を開くことができる。第3の部材46は、作業者が指を引っ掛けて作業しやすい形状であればいずれの形状でもよい。 A third member 46 is fixed to the front surface of the second member 45 using an adhesive such as an adhesive. The third member 46 is formed one size smaller than the second member 45, has a larger thickness than the second member 45, and is set smaller than the first member 41. The third member 46 constitutes a locking portion on which the operator hooks his/her finger, and the operator can open the fastener 30 by hooking his/her finger on the lower surface or upper surface of the third member 46 . The third member 46 may have any shape as long as it is a shape that allows the operator to easily hook his or her fingers thereon.

なお、本体部40は磁石31を収容し、板バネ11などの弾性部材を取付けることができればよく、必ずしも第1の部材41、第2の部材45、第3の部材46から構成される必要はない。例えば、第2の部材45と第3の部材46とが一体形成されていてもよく、本体部40全体が一体形成されていてもよく、4つ以上の部材から構成されていてもよい。 Note that the main body portion 40 only needs to be able to accommodate the magnet 31 and attach an elastic member such as the leaf spring 11, and does not necessarily need to be composed of the first member 41, the second member 45, and the third member 46. do not have. For example, the second member 45 and the third member 46 may be integrally formed, the entire main body portion 40 may be integrally formed, or may be composed of four or more members.

掲示具10は、初期状態において留め具30が掲示部材20に接触している。作業者は例えば留め具30の第2の部材45の係止部45aや第3の部材46の上面に指を係止して留め具30を開方向に移動させる。すると、ある位置で板バネ11の付勢力が磁石31と掲示面21との間の吸引力に勝り、作業者が力を加えなくても板バネ11の付勢力により留め具30は掲示部材20から離れていき、留め具30は、図7に示すように、留め具30の重量と弾性部材の付勢力とが釣り合う位置で板バネ11に支持される。 In the bulletin board 10, the fastener 30 is in contact with the bulletin board member 20 in the initial state. The operator moves the fastener 30 in the opening direction by, for example, locking a finger on the locking portion 45a of the second member 45 of the fastener 30 or the upper surface of the third member 46. Then, at a certain position, the urging force of the leaf spring 11 overcomes the attractive force between the magnet 31 and the bulletin board surface 21, and the urging force of the leaf spring 11 causes the fastener 30 to move against the bulletin board member 20 without the operator applying any force. As shown in FIG. 7, the fastener 30 is supported by the leaf spring 11 at a position where the weight of the fastener 30 and the biasing force of the elastic member are balanced.

そして、作業者は、掲示物Pを掲示部材20の掲示面21上に配置し、留め具30を閉方向に移動させる。ある位置で磁石31と掲示面21との間の吸引力が板バネ11による付勢力に勝り、作業者が力を加えなくても吸引力により留め具30が掲示面21に吸着する。 Then, the operator places the bulletin board P on the bulletin board surface 21 of the bulletin board member 20 and moves the fastener 30 in the closing direction. At a certain position, the attractive force between the magnet 31 and the bulletin board 21 overcomes the urging force by the leaf spring 11, and the fastener 30 is attracted to the bulletin board 21 by the attractive force without any force applied by the operator.

上記の実施形態の掲示具10及び掲示装置1によれば、磁石31を備える留め具30が板バネ11により掲示部材20と連結されているため、掲示物Pを掲示具10に止める際に、留め具30が落下したり留め具30が失われたりすることがなく、着脱作業効率が良い。 According to the bulletin board 10 and the bulletin board device 1 of the embodiments described above, since the fastener 30 including the magnet 31 is connected to the bulletin board member 20 by the leaf spring 11, when the bulletin board P is fastened to the bulletin board 10, There is no possibility that the fastener 30 will fall or be lost, and the attachment/detachment work is efficient.

また、留め具30と掲示部材20は板バネ11などの弾性部材により連結されているため、作業者は留め具30を掲示面21に近づける動作、離す動作を行うと、ある位置からは作業者が力を加えなくても留め具30は磁石31と掲示面21との間の吸引力により吸着または弾性部材の付勢力により掲示面21から離れ、作業者に余分な力が不要であり、作業が楽である。 In addition, since the fastener 30 and the bulletin board member 20 are connected by an elastic member such as the leaf spring 11, when the worker moves the fastener 30 closer to or away from the bulletin board 21, the worker can Even without applying any force, the fastener 30 separates from the bulletin board 21 due to the attractive force between the magnet 31 and the bulletin board 21 or due to the biasing force of the elastic member, eliminating the need for the operator to apply extra force and making the work easier. is easy.

また、磁石31にヨーク32を取付けているため、ヨーク32の先端部32b、32bにおいて吸引力が発生し、ヨーク32を用いない場合に比べて留め具30の吸引力を向上させることができる。 Further, since the yoke 32 is attached to the magnet 31, an attractive force is generated at the tip portions 32b, 32b of the yoke 32, and the attractive force of the fastener 30 can be improved compared to the case where the yoke 32 is not used.

また、板バネ11を用いることで、簡単に留め具30を掲示部材20に取付けることができる。 Further, by using the leaf spring 11, the fastener 30 can be easily attached to the bulletin board member 20.

さらに、留め具30の第3の部材46や第2の部材45の第1の部材41からはみ出た部分は、作業者が指を掛ける係止部を構成し、このような係止部が設けられていることで、作業者は留め具30を把持しやすく、留め具30の開閉の作業が行いやすくなる。 Further, the third member 46 of the fastener 30 and the portion of the second member 45 protruding from the first member 41 constitute a locking portion on which the operator hangs his/her finger, and such a locking portion is provided. This makes it easier for the operator to grasp the fastener 30 and to open and close the fastener 30.
