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 as a separate body from the bulletin board, the magnet may fall or be lost during the mounting work of the bulletin board. There is a problem that work efficiency is poor.

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 by paying attention to the above-mentioned problems, and an object of the present invention is to provide a bulletin board tool in which a magnet does not come off from a bulletin board and the work of attaching and detaching a 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。 The bulletin board according to the present invention is provided with a bulletin board for stopping the bulletin board, and at least a part of the bulletin board has a bulletin board member which is a mounting surface made of a magnetic material and a magnet attracting the magnetic material. It is provided with a fastener for sandwiching and fixing a bulletin board between the surface and an elastic member that connects the fastener to the bulletin board member and urges the fastener in a direction away from the bulletin board 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 fastener provided with the magnet is connected to the bulletin board by an elastic member, the fastener may fall or be lost when the bulletin board is fixed to the bulletin board. There is no, and the work efficiency of attachment and detachment is good.

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 fastener is urged by the elastic member in the direction away from the bulletin board member, when the operator brings the fastener closer to the bulletin board surface, the attractive force between the magnet and the bulletin board surface becomes elastic at a certain position. It is superior to the urging force of the member, and the fastener is attracted to the bulletin board surface by the suction force without applying force by the operator. Further, when the worker separates the fastener from the bulletin board member, the urging force of the elastic member exceeds the attractive force between the magnet and the bulletin board member at a certain position, and the urging force causes the worker to apply no force. The fasteners should be separated from the bulletin board. The fastener is supported by the elastic member at a position corresponding to the weight of the fastener and the urging 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, when the operator first applies force to the fastener to bring the fastener closer to or away from the bulletin board surface, the fastener is displayed as a magnet from a certain position without the operator applying force. Since it is attracted by the suction force between the surface and the elastic member is separated from the bulletin board surface by the urging force, the operator does not need an extra force and the work is easy.

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, the end of the yoke protrudes from the end face of the magnet, and the end of the yoke contacts the attachment 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 comprises a main body for accommodating the magnet, and the main body is provided with a locking portion for an operator to hook a finger on 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 made of a rod-shaped member, a plurality of the fasteners, and a plurality of elastic members for connecting each of the fasteners to the bulletin board member are provided, and the plurality of fasteners are the bulletin board members at predetermined intervals.

In the following description, the bulletin board 21 side to which the fastener 30 is attached in FIG. 2 will be described as the front side or the front side. The fastener 30 is provided on the surface of the bulletin board member 20 opposite to the audience seat side so that the bulletin board 10 cannot be seen from the audience seat side when the bulletin board 10 descends 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。 The shape of the bulletin board member 20 is not limited to this embodiment, and the cross-sectional shape may be, for example, a substantially square shape or a polygonal shape. Further, the bulletin board member 20 may be made of a non-magnetic material, and at least a part 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 form the mounting surface 22. Further, 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 the present embodiment, a picture rail 12 having substantially the same length as the bulletin board member 20 is screwed to the lower surface of the bulletin board member 20, and a hook with a wire is locked to the picture rail 12 to post a picture or the like. The object P can be attached. The 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 40 in which the magnet 31 is embedded. The magnet 31 is formed in 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 joint iron and is made of a soft magnetic material such as silicon iron or stainless steel. The yoke 32 is formed in a U-shaped cross section having a bottom wall 32A and both side walls 32B and 32B. Screw holes 32a are provided through the bottom wall 32A at two locations, and countersunk screws 33 for fixing the yoke 32 are passed through the screw holes 32a, and as shown in FIG. 3, The screw hole 32a has a shape corresponding to the head 33a of the countersunk screw 33. The number of screw holes 32a and the types of screws are not limited to this embodiment. The magnet 31 is fixed to the inside of the yoke 32 by an adhesive means such as an adhesive so that the bottom wall 32A and the side walls 32B and 32B of the yoke 32 come into contact with the front surface 31a, the upper surface 31b, and the lower surface 31c, respectively. .. Since the heights of the side walls 32B and 32B of the yoke 32 are set higher than the height of the magnet 31, as shown in FIGS. 3, 4 and 6, the tips 32b of the side walls 32B and 32B of the yoke 32 , 32b project to the rear side of the back surface 31d (end face) of the magnet 31. As shown in FIGS. 3 and 4, the tip portions 32b and 32b of the yoke 32 come into contact with the mounting surface 22 via the bulletin board P, so that the bulletin board P is fixed to the bulletin board 21 by the fastener 30. Will be possible. By providing the yoke 32 in this way, the yoke 32 forms a magnetic circuit together with the magnet 31, and attractive force is generated at the tip portions 32b and 32b of the yoke 32, so that the fastener 30 is compared with the case where the yoke 32 is not used. The suction power of the magnet is improved. The yoke 32 may have a bottom wall 32A and four side walls, and the tips of the four side walls may project to the rear side of the back surface 31d of the magnet 31.

The upper end portion of the first member 41 on the front surface 41d side 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 plate-shaped 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 the screw 14 into the screw hole of the leaf spring 11 and the screw hole 24 formed in the upper surface 23 of the bulletin board member 20. The leaf spring 11 urges the fastener 30 in a direction away from the bulletin board member 20 (opening direction). In the present embodiment, since the leaf spring 11 follows the second rounded portion 43a when the fastener 30 is opened and closed, the leaf spring is compared with a state in which the fastener 30 is not provided with the second rounded portion 43a and the corner portion is left. The fastener 30 is smoothly opened and closed without the 11 hitting the corner. The leaf spring 11 is fixed to the first member 41 and the bulletin board member 20 by a screw, but the leaf spring 11 is not limited to the screw and may be welded, for example, and the leaf spring 11 is attached to the first member 41 and the bulletin board member 20. 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。 The elastic member is not limited to the leaf spring 11, as long as the fastener 30 can be urged in the direction away from the bulletin board member 20, and may be, for example, 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 an adhesive means such as an adhesive. The second member 45 also covers the leaf spring 11 fastened to the front surface 41d of the first member 41 with a screw 13, but since the thickness of the leaf spring 11 is sufficiently small, the second member 45 is attached. Does not affect. The second member 45 is a substantially rectangular flat plate member, which is formed to be one size larger than the first member 41, and the portion of the second member 45 protruding from the first member 41 is an operator. Consists of a locking portion 45a on which a finger is hooked. Further, the second member 45 hides the screw hole 41c for attaching the yoke 32 appearing on the front surface 41d of the first member 41, and the screw hole 43b and the screw 13 for attaching the leaf spring 11. As shown in FIG. 4, a recess for accommodating the screw head of the screw 13 is provided on the back surface of the second member 45 at a position corresponding to the screw hole for fixing the leaf spring 11 of the first member 41. The 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 by an adhesive means such as an adhesive. The third member 46 is formed to be one size smaller than the second member 45, has a larger thickness than the second member 45, and is set to have a smaller thickness than the first member 41. The third member 46 constitutes a locking portion on which the operator hooks a finger, and the operator can hook a finger on the lower surface or the upper surface of the third member 46 to open the fastener 30. The third member 46 may have any shape as long as it is easy for the operator to hook his / her finger to work.

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。 It is sufficient that the main body 40 accommodates the magnet 31 and can be attached with an elastic member such as a leaf spring 11, and does not necessarily have to be composed of the first member 41, the second member 45, and the third member 46. Absent. For example, the second member 45 and the third member 46 may be integrally formed, the entire main body 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. For example, the operator locks 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 to move the fastener 30 in the opening direction. Then, at a certain position, the urging force of the leaf spring 11 exceeds the attractive force between the magnet 31 and the bulletin board 21, and the fastener 30 is made of the bulletin board member 20 by the urging force of the leaf spring 11 even if the operator does not apply 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 urging 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 worker arranges 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 exceeds the urging force of the leaf spring 11, and the fastener 30 is attracted to the bulletin board 21 by the attractive force even if the operator does not apply any force.

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 above embodiment, since the fastener 30 provided with the magnet 31 is connected to the bulletin board member 20 by the leaf spring 11, when the bulletin board P is stopped at the bulletin board 10 The fastener 30 does not fall or the fastener 30 is not lost, and the attachment / detachment work efficiency is good.

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。 Further, since the fastener 30 and the bulletin board member 20 are connected by an elastic member such as a leaf spring 11, when the operator performs an operation of bringing the fastener 30 closer to the bulletin board 21 and an operation of releasing the fastener 30, the operator can move the fastener 30 from a certain position. Even if no force is applied, the fastener 30 is attracted by the attractive force between the magnet 31 and the bulletin board 21 or separated from the bulletin board 21 by the urging force of the elastic member, and the operator does not need an extra force to perform the work. 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, 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 as compared with 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, a portion of the fastener 30 that protrudes from the third member 46 or the first member 41 of the second member 45 constitutes a locking portion on which the operator hangs a finger, and such a locking portion is provided. This makes it easier for the operator to grip the fastener 30 and makes it easier to open and close the fastener 30.
