本発明は、主として壁体などに沿って設けられる棚や吊り掛け物体を支持するのに用いられる荷重支持装置に関するものである。   The present invention relates to a load support device used mainly to support a shelf or a suspended object provided along a wall or the like.

従来、建物の屋内で壁面に棚を設けたり、厨房用具などを吊り掛けるには、棚を設置する場合、その棚支持アームもしくはブラケットを少なくとも二つ、所要の間隔を置いて主に柱など構造物の頑丈な部材に基部を取り付けて前方へ並行して突き出すようにされ、それら支持アームもしくはブラケット上に棚板を載せて支持されるようにされている。   Conventionally, in order to install shelves on the wall surface inside a building or to hang kitchen utensils etc., when installing shelves, at least two shelves supporting arms or brackets, mainly pillars structure with a required interval A base is attached to a sturdy member of the object and protrudes in parallel to the front, and a shelf board is placed on the support arm or bracket to be supported.

ところで、前記棚支持アーム（またはブラケット）は建物の壁面、好ましくは柱の位置に基部を釘もしくは木ねじなどによって固定され、固定されたその棚支持アーム（またはブラケット）の支持面に棚板を受支させて棚が形成されることになり、構造的にがたつきのない支持構造が求められている。また、店舗などで商品を展示する陳列棚などは、店舗装飾の観点から装飾性も必要となり、その支持具について取付部が露出するものでは好ましくない。そこで、取付部を簡素化して壁面に装着できるように、壁構造部に孔をあけて、その孔に基部を挿入して固定できるようにされた陳列用アタッチメント（支持具）が、例えば特許文献１によって知られている。   By the way, the shelf support arm (or bracket) is fixed to the wall surface of the building, preferably a column, by a nail or a wood screw, and the shelf support arm (or bracket) receives the shelf plate on the support surface. A shelf is formed by supporting it, and a support structure that is structurally free from shaking is required. In addition, display shelves that display products in stores and the like also require decorativeness from the viewpoint of store decoration, and it is not preferable that the mounting portion is exposed for the support. In view of this, a display attachment (support) in which a hole is formed in a wall structure portion and a base portion can be inserted and fixed so that the mounting portion can be simplified and mounted on a wall surface is disclosed in, for example, Patent Document Known by 1.

前記特許文献１によって知られるものは、陳列用アタッチメントとして、二重構造の支持部材に設けられた支持孔に、外部で操作できるラッチ爪を内蔵させたアタッチメントの一端部に設けた当接面が支持部材の表面に当接するまで延長軸部を挿入すると、前記ラッチ爪と当接面とによって支持部材を挟み付けるとともに、その延長軸の先端と支持部材に設けられた延長軸先端を受入れる孔とでアタッチメントを支持する。そして取り外すときにはラッチ爪を外部から操作できるようにして、そのラッチ爪による係止を解いて簡単に抜き出せるようにされたものが記載されている。   As disclosed in Patent Document 1, a contact surface provided at one end of an attachment in which a latch claw that can be externally operated is built into a support hole provided in a support member having a double structure as a display attachment. When the extension shaft portion is inserted until it comes into contact with the surface of the support member, the support member is sandwiched between the latch claw and the contact surface, and the tip of the extension shaft and a hole for receiving the tip of the extension shaft provided on the support member, Support the attachment with. In addition, it is described that the latch pawl can be operated from the outside when it is removed, and the latch pawl is unlocked so that it can be easily pulled out.

しかしながら、前記先行技術にあって、例えば特許文献１によって知られるものでは、壁構造部に対するアタッチメントの着脱操作が簡単にできるので便利であるが、その支持部材、すなわち壁体として二重構造の壁体が必要で、その外面から内部の支持部材に対する装着部（延長軸）の長さが特定されるので、この物品の寸法に合った支持壁に対してでないと使用できないという問題点がある。さらに、その二重構造の壁体に前と後（奥部）とに軸心を合致させて現場作業で挿入支持孔を設ける必要があるため、その軸心を合致させた挿入孔の形成が困難である。そのために、どうしても手前側の挿入孔の口径が所定寸法より大きくしないと、アタッチメントの挿入支持ができず、理想的には簡単で有効な支持具とされるも、現実には装着後取付部でガタが生じて安定せず不具合であるという問題点がある。   However, in the above-mentioned prior art, for example, what is known from Patent Document 1 is convenient because the attachment / detachment operation of the attachment to / from the wall structure can be easily performed. Since the body is necessary and the length of the mounting portion (extension shaft) with respect to the internal support member is specified from the outer surface, there is a problem that the body cannot be used unless the support wall matches the size of the article. Furthermore, since it is necessary to provide an insertion support hole in the field work by matching the axial center of the double-structured wall body to the front and rear (back), it is possible to form an insertion hole that matches the axial center. Have difficulty. Therefore, if the diameter of the insertion hole on the front side is not larger than the predetermined size, the attachment cannot be inserted and supported, and it is ideally a simple and effective support tool. There is a problem that it is not stable because of looseness.

また、一般に、商品を販売する店舗などでは、定期的にあるいは不定期で店舗内に展示販売している商品を載せる商品棚や吊下げ具などを店舗のデザインに合わせて配置換えすることがしばしば行われている。そのために、壁面に取付けられる棚などの支持部材は、状態に応じて位置換えする必要が生じる。このようなことから位置移動が容易な棚とその支持部材が要望され、棚の移動に伴う壁面の装飾性の維持が求められるが、前述のような支持具ではその支持孔の形成と管理に問題があり好ましくない。   Also, in general, in stores that sell products, it is often the case that product shelves and hanging tools on which products that are displayed and sold in stores are placed regularly or irregularly are rearranged according to the store design. Has been done. Therefore, the support member such as a shelf attached to the wall surface needs to be repositioned according to the state. For this reason, there is a demand for a shelf and its supporting member that can be moved easily, and it is required to maintain the decorativeness of the wall surface as the shelf moves. There is a problem and it is not preferable.

本発明はこのような問題点を解決するためになされたもので、建物の壁面構造に対して厚さ寸法を極薄くしてガイド溝を備えた構造で壁体側に埋設できるレール状の支持部材に、棚などの荷重支持体を、所要の位置に固定できて支持基部が露出しないで安定状態に支持できる荷重支持装置を提供することを目的とする。   The present invention has been made to solve such problems, and is a rail-like support member that can be embedded on the wall body side with a structure having a guide groove with an extremely thin thickness dimension relative to the wall structure of the building. Another object of the present invention is to provide a load support device that can fix a load support such as a shelf in a required position and can support it in a stable state without exposing a support base.

このような目的を達成するために、本発明による荷重支持装置は、
開口の両縁に内向き突縁部を備えた案内溝を全長にわたり形成されて建物などの躯体に固定される支持部材と、この支持部材の前記案内溝に嵌って所要の位置で拡張させると係止固定できる拡張固定部材、およびこの拡張固定部材によって前記支持部材に保持されて前方に突出す荷重支持体とでなり、その荷重支持体にて被支持体を支持するようにした荷重支持装置において、
前記拡張固定部材は、受部片と押え部片とで構成され、この受部片と押え部片を組合わせた状態で、これらに直交する方向に中央部を貫通して荷重支持部材取付孔が設けられ、前記受部片と押え部片とがその肉厚方向に互いに形成される段部を重ね合わせて、前記受部片の側端部と前記押え部片の段形成部内側部とに両部片が押え作用力を受けると幅方向に拡張できる傾斜面が形成され、前記荷重支持部材取付孔に挿入される荷重支持部材の基部を回動させることで前記案内溝内でその幅方向に前記受部片と押え部片とが拡張して係止固定されるように構成されていることを特徴とするものである（第１発明）。 In order to achieve such an object, the load supporting device according to the present invention is:
A guide groove having a inwardly projecting edge on both edges of the opening is formed over the entire length and the support member that will be fixed to the skeleton, such as a building, when expanded in desired position fitted in the guide groove of the support member expansion fixing member that can be locked and fixed, and this extension fixing member thus being retained in the support member becomes between load bearing body protruding forward and adapted to support the supported member at the load support In the load support device,
The expansion fixing member is composed of a receiving piece and a holding piece, and in a state in which the receiving piece and the holding piece are combined, the load fixing member mounting hole penetrates the central portion in a direction perpendicular to the receiving piece and the holding piece. The receiving part piece and the pressing part piece are overlapped with each other in the thickness direction, and the side end part of the receiving part piece and the step forming part inside part of the pressing part piece are overlapped. An inclined surface that can expand in the width direction is formed when both pieces receive a pressing force, and the width of the load support member inserted into the load support member mounting hole is turned by rotating the base of the load support member. The receiving piece and the holding piece are expanded and locked in the direction (first invention).

前記第１発明において、前記受部片と押え部片との拡縮方向の外側面には、前記支持部材における案内溝に形成される突縁部と係合して抜け出しを防止する凹み部がそれぞれ形成されているのがよい（第２発明）。 In the first aspect of the present invention, the outer surface in the expansion / contraction direction of the receiving portion piece and the holding portion piece has a recess portion that engages with a protruding edge portion formed in a guide groove in the support member to prevent the supporting portion piece from coming out. It is good to be formed ( 2nd invention).

また、前記拡張固定部材における受部片には、鍵穴状の前記荷重支持部材取付孔がその細径部が長軸方向に直交するようにして設けられ、かつ裏面に前記荷重支持部材の基部に取付く係止ピンの移動カム面が前記細径部位置からほぼ９０度の範囲で扇形状に刻設されているのがよい（第３発明）。 Further, the receiving piece in the expansion fixing member is provided with the load supporting member mounting hole in the shape of a keyhole so that the small diameter portion is orthogonal to the major axis direction, and on the back surface on the base of the load supporting member The moving cam surface of the locking pin to be attached is preferably engraved in a fan shape within a range of approximately 90 degrees from the position of the narrow diameter portion ( third invention).

さらに、前記荷重支持部材は、基端部を前記拡張固定部材取付孔に挿入して締結固定する軸部を備える基軸部材と、この基軸部材に着脱可能に連結して荷重を支える支持アームとで構成され、前記基軸部材を軸周りに回転操作することにより前記拡張固定部材を前記支持部材の案内溝部に固定あるいは固定解除できる構成であるのがよい（第４発明）。 Further, the load support member in the base shaft member having a shaft portion fastened by inserting the proximal end portion to the extended fixing member attachment hole, a support arm for supporting a load and removably coupled to the base shaft member is configured, the base shaft member it is preferable the extended fixing member by rotational operation around an axis which is fixed or unlocking can Ru configuration in the guide groove of the support member (fourth invention).

また、前記支持アームは、所要の間隔で配置される少なくとも二本の前記支持部材に組み込まれた前記拡張固定部材に、基端を固定される前記基幹部材にて連結保持されて平行に配置され、それらの上側に棚部材を載置して棚が支持形成される構成であるのがよい（第５発明）。 Moreover, the support arm is in the extended fixing member incorporated in said support member of at least two arranged at required intervals, arranged in parallel coupled held by the core member secured to the proximal end It is preferable that the shelf member is placed on the upper side thereof so that the shelf is supported and formed (the fifth invention).

本発明においては、建物などの壁面に取付けた支持部材の案内溝内に拡張機能を備える拡張固定部材を挿入し、この拡張固定部材に設けられている荷重支持部材取付孔に支持アームを連結した荷重支持部材の基部を挿入し、その荷重支持部材を軸周りに回動することにより、前記拡張固定部材を構成する受部片と押え部片とが重ね合わせ部における段部と側端部との傾斜面に沿って幅方向にスライドして案内溝の両突縁部の内側に前記受部片と押え部片との側端部が係合されて接触摩擦力を高め、当該位置にて支持部材に荷重支持部材が固定保持される。したがって、本発明によれば、建物側に前記支持部材を付設してあれば、その支持部材の案内溝に前記拡張固定部材を外部から挿入し、その拡張固定部材の荷重支持部材取付孔に荷重支持部材の基部を差し込んで軸周りに回動させるだけで、拡張固定部材を当該位置にて拡張固定すると同時に荷重支持部材が固定されて前方に突出した状態で取付けられるので、この要領で所要の間隔をおいて配設された支持部材にそれぞれ荷重支持部材を取付ければ、それら荷重支持部材の支持アーム部によって被支持体（棚板など）を簡単に架設することができる。 In the present invention, by inserting an expansion fixing member comprising an extension to the guide groove of the support member mounted on the wall, such as a building, and connecting the support arm to the load bearing member mounting holes are provided in this expansion fixing member By inserting the base portion of the load support member and rotating the load support member around the axis, the receiving piece and the presser piece constituting the expansion fixing member are separated from the step portion and the side end portion in the overlapping portion. The side end portions of the receiving piece and the holding piece are engaged with the inner sides of the two protruding edges of the guide groove to increase the contact friction force at the position. The load support member is fixedly held on the support member. Therefore, according to the present invention, if the support member is provided on the building side, the extension fixing member is inserted from the outside into the guide groove of the support member, and a load is applied to the load support member mounting hole of the extension fixing member. Just by inserting the base of the support member and rotating it around the axis, the expansion fixing member is expanded and fixed at that position and at the same time the load support member is fixed and attached in a protruding state. If load support members are attached to the support members arranged at intervals, a supported body (a shelf board or the like) can be easily installed by the support arm portions of the load support members.

また、本発明によれば、支持部材の案内溝内で拡張固定部材を、装着する荷重支持部材によって重ね合わせ方向に加える推力で、受部片と押え部片との係合する傾斜面によって拡張方向に作用させて案内溝内での固定力を確保できるので、簡単に固定操作ができる。また、その推力を除くことにより拡張固定部材による案内溝内での係止力が解除でき、その操作は荷重支持部材を回動操作するだけで簡単に行うことができるという利点がある。 Further , according to the present invention , the expansion fixing member is expanded in the guide groove of the support member by the inclined surface where the receiving piece and the holding piece are engaged by the thrust applied in the overlapping direction by the load supporting member to be mounted. Since the fixing force in the guide groove can be secured by acting in the direction, the fixing operation can be easily performed. Further, by removing the thrust force , the locking force in the guide groove by the expansion fixing member can be released, and the operation can be easily performed only by rotating the load support member.

また、第２発明の構成を採用することにより、支持部材に形成される案内溝内で拡張固定部材を挿入して荷重支持部材を支持させる際、大きく荷重が作用しても外向きに抜け出すのを確実に防止できる。また、案内溝内をスライドさせるときにも抜け落ちるのを防止できるという利点がある。 In addition, by adopting the configuration of the second invention, when the expansion support member is inserted into the guide groove formed in the support member to support the load support member, the load support member is pulled out outward even if a large load is applied. Can be reliably prevented. Further, there is an advantage that it can be prevented from falling off when sliding in the guide groove.

また、第３発明によれば、拡張固定部材を拡張固定する操作が荷重支持部材の回動によって背後から締め付けて確実に行えるようにするとともに、その荷重支持部材の基軸部が抜け出すのを防止する。また、固定操作と逆に操作することで固定を解除させることができる。したがって、支持部材の案内溝に沿って支持位置を変える場合、固定力を解除させれば、そのままスライドさせて任意の位置に変更することができるという利点がある。 In addition, according to the third aspect of the present invention, the operation for expanding and fixing the expansion fixing member can be reliably performed by tightening from behind by the rotation of the load support member, and the base portion of the load support member is prevented from coming out. . Further, the fixing can be released by operating in the reverse direction to the fixing operation. Therefore, when changing the support position along the guide groove of the support member, if the fixing force is released, there is an advantage that it can be slid as it is and changed to an arbitrary position .

さらに、第４発明および第５発明によれば、荷重支持部材が拡張固定部材に取付く軸部を備える基軸部とその基軸部に着脱可能に連結される支持アームとからなるので、その支持アームを交換することにより棚板の支持以外に、例えば支持アームを傾斜して取付く構造のものとすれば、多数の衣料（例えば服）などを位置をずらせて吊り掛けて展示するような陳列支持具とすることができる。なお、棚支時部材として用いる場合は、等条件で少なくとも二本の支持部材を配列して棚板を支持するようにするのがよい。 Further, according to the fourth invention and the fifth invention, since the load bearing member comprises a base shaft portion having an attachment rather shank to extend the fixed member and the supporting arm is detachably connected to the base shaft portion, the support arm In addition to supporting the shelf board by exchanging the rack, for example, if the support arm is tilted and mounted, the display support is such that a large number of clothes (for example, clothes) are suspended and displayed at different positions. Can be used as a tool. In the case of using as a shelf支時member, it is preferable so as to support the shelf plate by arranging at least two support members at equal conditions.

次に、本発明による荷重支持装置の具体的な実施の形態について、図面を参照しつつ説明する。   Next, specific embodiments of the load supporting device according to the present invention will be described with reference to the drawings.

前記支持部材２は、断面が扁平なハット形に形成された長尺の部材で、例えばアルミニウムの押出し成形により得られるもので、その中央部に案内溝３が形成されて、両外側に張出す部分が取付座４となっている。また、前記案内溝３の開口部３ａ寄りの内側には相対向して突縁部５がそれぞれ形成されており、それらの突縁部５に案内溝３の開口方向にそれぞれ細い溝６が形成されている。この支持部材２は、両外側の取付座４に設けた取付孔（図示せず）で釘・小ネジなどによって壁面Ａなど構築物支持面に固定できるようになっている。   The support member 2 is a long member formed in a hat shape with a flat cross section, and is obtained, for example, by extrusion molding of aluminum. A guide groove 3 is formed in the center portion of the support member 2 and projects outward. The part is a mounting seat 4. Further, projecting edge portions 5 are formed on the inner side of the guide groove 3 near the opening portion 3a so as to face each other, and narrow grooves 6 are formed on the projecting edge portions 5 in the opening direction of the guide groove 3, respectively. Has been. The support member 2 can be fixed to a structure support surface such as a wall surface A by a nail, a small screw or the like through mounting holes (not shown) provided in the mounting seats 4 on both outer sides.

前記拡張固定部材１０は、図３および図４に示されるように、受部片１１と押え部片１２と両者を前面側から囲って保持するカバー部片１６とで構成されている。受部片１１は、中央に鍵孔状の軸挿入孔１４（本発明の荷重支持部材取付孔に相当）が設けられて、幅が前記案内溝３よりも狭い幅寸法で、やや肉厚にされて幅方向に一側端を受け勾配１１ｃに形成され、その反対側端部には案内溝３内に挿入して一方の突縁部５と係合する段付き１１ａの形状とされている。また、その受部片１１上面は、段部１１ｂを付して押え部片１２と重ね合わすと前記案内溝３内で摺動できる厚さ寸法となるようにされている。さらに、受部片１１の裏面には、前記鍵孔状の軸挿入孔１４における細径部１４ａに隣接して扇形状のカム面１３が刻設され、そのカム面１３は孔位置から回転方向に次第に高くなるように形成されている。   As shown in FIGS. 3 and 4, the expansion fixing member 10 includes a receiving piece 11, a holding piece 12, and a cover piece 16 that surrounds and holds both from the front side. The receiving piece 11 is provided with a keyhole-shaped shaft insertion hole 14 (corresponding to the load supporting member mounting hole of the present invention) in the center, and has a width that is narrower than the guide groove 3 and is slightly thicker. Then, one side end in the width direction is formed to have a slope 11c, and the opposite end is formed into a stepped shape 11a that is inserted into the guide groove 3 and engages with one protruding edge 5. . Further, the upper surface of the receiving piece 11 has a thickness dimension that allows sliding within the guide groove 3 when the stepped portion 11 b is provided and the holding piece 12 is overlapped with the holding piece 12. Further, a fan-shaped cam surface 13 is engraved on the back surface of the receiving piece 11 adjacent to the narrow-diameter portion 14a of the keyhole-shaped shaft insertion hole 14, and the cam surface 13 rotates in the direction of rotation from the hole position. It is formed so as to gradually become higher.

一方、押え部片１２は、前記受部片１１とほぼ同幅寸法で、その受部片１１の上面に重ね合える薄肉の部分と受部片１１の受勾配にされた側端部に係合して幅方向に拡張動作できるようにされる勾配面１２ａを内側に形成たれた段付き形状にされ、受部片１１と重ね合わせた状態で前記鍵孔状の軸挿入孔１４と孔位置がほぼ合致する軸の挿入孔１４’が形成され、かつその軸の挿入孔１４’からやや離れて前後位置を切欠いた形状１２ｃにされている。なお、前記受部片１１の軸挿入孔１４を挟んで図上左右に小ネジ孔１１ｄが設けられており、カバー部片１６と組合わせたときに押え部片１２を挟んで小ネジ１７により離脱しないように組み付けられる構成となっている。   On the other hand, the holding piece 12 has substantially the same width as the receiving piece 11 and is engaged with a thin portion that can be overlapped with the upper surface of the receiving piece 11 and a side end portion of the receiving piece 11 that is made to have a receiving gradient. Then, the stepped shape is formed on the inner side of the inclined surface 12a that can be expanded in the width direction, and the key hole-shaped shaft insertion hole 14 and the hole position are in a state of being overlapped with the receiving piece 11. A substantially matching shaft insertion hole 14 ′ is formed, and a shape 12 c is formed in which the front and rear positions are notched slightly apart from the shaft insertion hole 14 ′. In addition, small screw holes 11d are provided on the left and right in the figure across the shaft insertion hole 14 of the receiving piece 11, and when combined with the cover piece 16, the holding piece 12 is sandwiched by the small screw 17. It is configured to be assembled so as not to leave.

前記カバー部片１６は、前記支持部材２の開口部３ａ両側に形成されている細い溝６（カバー部片装着溝）に両端突縁１６ａがそれぞれ係合できるようにされた平板で、ほぼ中央部に前記鍵孔状の軸挿入孔１４と同形の軸挿入孔１６ｂが形成されている。なお、このカバー部片１６の長さ寸法は、前記受部片１１・押え部片１２と同程度になっている。   The cover piece 16 is a flat plate in which both end protrusions 16a can be engaged with the narrow grooves 6 (cover piece mounting grooves) formed on both sides of the opening 3a of the support member 2, respectively. A shaft insertion hole 16b having the same shape as the keyhole-shaped shaft insertion hole 14 is formed in the part. The length of the cover piece 16 is approximately the same as that of the receiving piece 11 and the holding piece 12.

前記荷重支持部材２０は、先端部に二股フォーク状の支持アーム取付部２１を備える軸体で、その基軸部２２から基端軸部２２ａを段付きで小径となるようにされ、その基端軸部２２ａを前記拡張固定部材１０の軸挿入孔１４に挿入して固定するようにされており、基端部分に軸線に直交してロックピン２３が植設されている。また、基軸部２２にも軸線に直交して係止ピン２４が植設されている。   The load support member 20 is a shaft body having a bifurcated fork-shaped support arm attachment portion 21 at the distal end portion, and is configured such that the proximal shaft portion 22a is stepped from the proximal shaft portion 22 to have a small diameter, and the proximal shaft thereof is provided. The portion 22a is inserted into and fixed to the shaft insertion hole 14 of the expansion fixing member 10, and a lock pin 23 is implanted in the base end portion perpendicular to the axis. A locking pin 24 is also implanted in the base shaft portion 22 so as to be orthogonal to the axis.

このように形成される荷重支持部材２０の基軸部２２には、保持部材２５が被嵌して拡張固定部材１０に対する保持力が高められるようにされている。この保持部材２５は、鍔付きの環状に形成されて、その中央の軸挿入孔２５ａを前側（鍔部２５ｃと反対の側）から所要寸法（端面から全体のほぼ半分）を太い径にした段付き孔２５ｂとされ、後側に係止ピン２４が挿入される切込み溝２６を形成されている。そして、前記鍔部２５ｃは前記カバー部片１６の幅寸法程度の直径に形成されており、保持部材２５後端部には、そのカバー部片１６における鍵状孔の細径部１４ａにはまり込む突起２５ｄが形成されている。前記突起２５ｄは、カバー部片１６の鍵状孔の細径部１４ａに嵌り込むことによって回り止めの役目を果たす。なお、図中符号２７はコイルスプリングで、荷重支持部材２０の基軸部２２と保持部材２５の段付き孔２５ｂとの間に介挿されて荷重支持部材２０の抜け止め機能を発揮できるようにされている。   A holding member 25 is fitted on the base shaft portion 22 of the load support member 20 formed in this way, so that the holding force for the expansion fixing member 10 is increased. The holding member 25 is formed in a ring shape with a flange, and the shaft insertion hole 25a at the center thereof has a required diameter (almost half of the whole from the end face) with a large diameter from the front side (the side opposite to the flange portion 25c). A cut-out groove 26 is formed on the rear side to form a locking hole 24b. The flange portion 25c is formed to have a diameter approximately equal to the width of the cover piece 16, and the holding member 25 is fitted into the narrow end portion 14a of the key hole in the cover piece 16 at the rear end portion thereof. A protrusion 25d is formed. The protrusion 25d serves as a detent by being fitted into the narrow diameter portion 14a of the key hole of the cover piece 16. In the figure, reference numeral 27 denotes a coil spring which is inserted between the base shaft portion 22 of the load support member 20 and the stepped hole 25b of the holding member 25 so as to exhibit a function of preventing the load support member 20 from coming off. ing.

荷重支持部材２０の支持アーム取付部２１は、荷重となる被支持体として、例えば棚支持部材の場合、その基端を溝部２１ａに嵌め合わせて連結ピン２８により支持アーム３０を結合できるようにされている。そのために、支持アーム３０（主に棒状のもの。ただし、これに限定されない）の基端は、前記支持アーム取付部２１の溝２１ａ内端（溝底）と当接して係止されるようにするのがよい。また、例えば傾斜する支持アームを装着する場合は、その基端が前記支持アーム取付部２１の溝２１ａ底と当接して所要の傾斜角で固定されるように形成したものを用いるのがよい。   For example, in the case of a shelf support member, the support arm mounting portion 21 of the load support member 20 can be coupled to the support arm 30 by the connecting pin 28 by fitting the base end thereof to the groove portion 21a. ing. Therefore, the base end of the support arm 30 (mainly rod-shaped but not limited thereto) is brought into contact with and locked to the inner end (groove bottom) of the groove 21a of the support arm mounting portion 21. It is good to do. Further, for example, when mounting an inclined support arm, it is preferable to use one that is formed so that its base end is in contact with the bottom of the groove 21a of the support arm mounting portion 21 and fixed at a required inclination angle.

このように構成される本実施形態の荷重支持装置１にあっては、例えば陳列棚を設置する場合、構築物の壁体に対して装飾壁面を構築するボードの取付時、支持部材２の本体部分が内側に嵌り込むような間隔を置いてボードを取り付け、その間隔を置いて形成された空間部に支持部材２を嵌め込んで両側の取付座４，４を釘や小ネジによってボードに固着し配置する。したがって、この支持部材２はボードの厚みよりやや厚い寸法であるのが好ましい。また、その取付位置はボードの取付作業時に設定できるので、棚支持に適合した間隔で複数列設ける。なお、前記ボードの取付座４，４が当接する部分は、図２によって示されるように、その取付座４の肉厚相当分切り込んで、取付後には支持部材２の取付座４表面がボードの他の表面と一致するようにされるのがよい。   In the load support device 1 of the present embodiment configured as described above, for example, when a display shelf is installed, the main body portion of the support member 2 is attached at the time of mounting a board for constructing a decorative wall surface to the wall body of the structure. Attach the board with an interval that fits inside, and insert the support member 2 into the space formed at that interval, and fix the mounting seats 4 and 4 on both sides to the board with nails or small screws. Deploy. Therefore, it is preferable that the supporting member 2 has a dimension slightly thicker than the thickness of the board. Further, since the mounting position can be set at the time of board mounting work, a plurality of rows are provided at intervals suitable for shelf support. As shown in FIG. 2, the portion of the board on which the mounting seats 4 and 4 abut is cut by an amount corresponding to the thickness of the mounting seat 4 so that the surface of the mounting seat 4 of the support member 2 is the surface of the board after mounting. It should be matched with other surfaces.

配設された支持部材２に対する拡張固定部材１０の組み込みは、まず、受部片１１と押え部片１２とを，図３（ａ）で示すように、受部片１１の端部の勾配面１１ｃと押え部片１２の内側段付き部における勾配面１２ａとを係合するように重ね合わせる。この状態で押え部片１２の外側にカバー部片１６を重ね、カバー部片１６側から小ネジ１７（皿頭小ネジが好ましい）を受部片１１の小ネジ孔１１ｄに合致させて三枚重ねで仮固定する。こうすることにより受部片１１と押え部片１２とは分離しない状態に保たれるので、前記支持部材２の案内溝３に対して端部から挿入して、その案内溝３内で移動可能な状態とする。   As shown in FIG. 3 (a), first, the extension fixing member 10 is assembled into the support member 2 disposed, and the receiving piece 11 and the holding piece 12 are inclined at the end surface of the receiving piece 11 as shown in FIG. 11c and the inclined surface 12a in the inner stepped portion of the presser piece 12 are overlapped so as to be engaged. In this state, the cover piece 16 is overlapped on the outer side of the holding piece 12, and a small screw 17 (preferably a flat head screw) is aligned with the small screw hole 11 d of the receiving piece 11 from the cover piece 16 side. Temporarily fix in layers. By doing so, the receiving piece 11 and the holding piece 12 are kept in a state where they are not separated, so that they can be inserted into the guide groove 3 of the support member 2 from the end and moved in the guide groove 3. State.

組合された拡張固定部材１０は、棚設置対応位置に移動させてカバー部片１６表面から三枚重ねで仮結合している小ネジ１７をゆるく締め込むことにより、カバー部片１６が支持部材２に固定される。この固定操作に際して、拡張固定部材１０の軸挿入孔１４が支持部材２に設けられている受孔とほぼ合致する位置に合わせる。この位置合わせには、例えば孔に挿入できる直径の棒材を用いると良い。   The combined expansion and fixing member 10 is moved to the position corresponding to the shelf installation, and the cover piece 16 is loosely tightened from the surface of the cover piece 16 by temporarily tightening three screws 17 so that the cover piece 16 is supported by the support member 2. Fixed to. In this fixing operation, the shaft insertion hole 14 of the expansion fixing member 10 is adjusted to a position that substantially matches the receiving hole provided in the support member 2. For this alignment, for example, a rod having a diameter that can be inserted into the hole may be used.

一方、荷重支持部材２０は、その基軸部２２に保持部材２５を外嵌めして組合わせた状態で基端軸部２２ａを、付設されるロックピン２３が拡張固定部材１０の鍵孔状の軸挿入孔１４の細径孔部１４ａに通じるようにして挿入する。   On the other hand, the load support member 20 has a base end shaft portion 22a in a state in which the holding member 25 is externally fitted to the base shaft portion 22, and the lock pin 23 attached thereto is a keyhole-shaped shaft of the expansion fixing member 10. The insertion hole 14 is inserted so as to communicate with the narrow hole portion 14a.

基端軸部２２ａを所定の位置まで挿入すると、ロックピン２３が拡張固定部材１０の受部片１１裏面側に設けられているカム面１３に対応する位置となる。さらに、荷重支持部材２０をその状態で基軸部２２に外嵌めしているコイルスプリング２７の復元力に抗して押し込むと、ロックピン２３がカム面１３上に当接するようになるので、そのまま荷重支持部材２０を回転させると、前記ロックピン２３がカム面１３により基軸部２２を支持部材２の内部方向に引き付けるように作用する。基軸部をほぼ９０°回転させる間に、ロックピン２３を介して受部片１１が押え部片１２との間で密接状態に変位することにより、その受部片１１の側端勾配面１１ｃと押え部片１２の内側段部の勾配面１２ａとの接触によって軸方向の挟持力が幅方向の拡張力に変換され、受部片１１と押え部片１２との両外側面が案内溝３の内側面に強く押付けられて接触摩擦力が高められるのである。また、同時に拡張固定部材１０の両外側の表側段部１１ｂ，１２ｂが支持部材２の案内溝３開口部両側の突縁部５，５と係合する。   When the proximal end shaft portion 22 a is inserted to a predetermined position, the lock pin 23 is positioned corresponding to the cam surface 13 provided on the back surface side of the receiving portion piece 11 of the expansion fixing member 10. Further, when the load supporting member 20 is pushed against the restoring force of the coil spring 27 that is externally fitted to the base shaft portion 22 in this state, the lock pin 23 comes into contact with the cam surface 13, so When the support member 20 is rotated, the lock pin 23 acts to attract the base shaft portion 22 toward the inside of the support member 2 by the cam surface 13. While the base shaft portion is rotated by approximately 90 °, the receiving piece 11 is displaced in close contact with the holding piece 12 via the lock pin 23, so that the side end slope surface 11c of the receiving piece 11 and The holding force in the axial direction is converted into an expanding force in the width direction by contact with the inclined surface 12 a of the inner step portion of the presser piece 12, and both outer side surfaces of the receiving piece 11 and the presser piece 12 are formed on the guide groove 3. It is strongly pressed against the inner surface to increase the contact friction force. At the same time, the front side step portions 11 b and 12 b on both outer sides of the expansion fixing member 10 are engaged with the protruding edge portions 5 and 5 on both sides of the opening of the guide groove 3 of the support member 2.

その結果、拡張固定部材１０が支持部材２の案内溝３内で固定され、この固定された拡張固定部材１０に基軸部２２が支持されると同時に、その軸端が支持部材２の孔に嵌合挿入されので、最早移動することなく固定される。したがって、この荷重支持部材２０の先端の支持アーム取付部２１に対して被支持体を支持する支持アーム３０の基端を連結ピン２８で連結すれば、壁面から前に支持アーム３０が水平に突き出された状態で維持される。このようにして所要間隔で配された複数の支持アーム３０上に棚部材３５を載せて支持させればよい。また、例えば衣服などの陳列吊掛けを行う傾斜支持アームの場合は、その支持アームの基端を前記支持アーム取付部２１に接続すれば直ちに使用可能な状態とすることができる。なお、荷重支持部材２０にはその基軸部２２に植設された係止ピン２４によって保持部材２５の内側段孔部２５ｂに嵌るコイルスプリング２７の蓄勢力で軸方向の引抜き方向への推力が作用して拡張固定部材１０の受部片１１と押え部片１２との係合力が高められて、支持部材２への固定力が維持される。   As a result, the expansion fixing member 10 is fixed in the guide groove 3 of the support member 2, and the base shaft portion 22 is supported by the fixed expansion fixing member 10, and at the same time, the shaft end is fitted in the hole of the support member 2. Because it is inserted, it is fixed without moving anymore. Therefore, if the base end of the support arm 30 that supports the supported body is connected to the support arm mounting portion 21 at the tip of the load support member 20 by the connecting pin 28, the support arm 30 protrudes horizontally from the wall surface. Maintained. In this way, the shelf members 35 may be placed and supported on the plurality of support arms 30 arranged at a required interval. For example, in the case of an inclined support arm that hangs clothes or the like, if the base end of the support arm is connected to the support arm attachment portion 21, it can be immediately put into use. The load supporting member 20 receives a thrust force in the axial pulling direction by the stored force of the coil spring 27 fitted into the inner step hole 25b of the holding member 25 by the locking pin 24 implanted in the base shaft portion 22. By acting, the engaging force between the receiving piece 11 and the holding piece 12 of the expansion fixing member 10 is increased, and the fixing force to the support member 2 is maintained.

こうして壁面Ａに対して支持部材２と拡張固定部材１０とを介して支持される支持アーム３０は、その拡張固定部材１０に取り付く荷重支持部材２０の基軸部２２が保持部材２５によってカバー部片１６の前面にて補助的に支持されるので、大きな負荷が作用しても無理なく保持することができる。なお、支持部材２の案内溝３の開口部については、前記カバー部片１６と同様断面の無孔で長尺のものを空白部の前に嵌め込むことで、全体として体裁よく仕上げることができる。したがって、装飾的な壁面が得られて効果的である。   In this way, the support arm 30 supported on the wall surface A via the support member 2 and the extension fixing member 10 has the base shaft portion 22 of the load support member 20 attached to the extension fixing member 10 by the holding member 25 and the cover piece 16. Since it is supported in an auxiliary manner on the front surface, it can be held without difficulty even when a large load is applied. In addition, about the opening part of the guide groove 3 of the supporting member 2, the non-hole of a cross section like the said cover part piece 16 and a long thing can be fitted in front of a blank part, and it can finish finely as a whole. . Therefore, a decorative wall surface is obtained and effective.

このようにして設けられた荷重支持装置１における荷重支持部材２０を取り外す際は、支持アーム３０を取り外して後に、保持部材２５を内装されているコイルスプリング２７の作用力に抗して手前に引き、突起２５ｄを軸挿入孔１４の細径部１４ａから引き離して回り止めを解除し、その後に荷重支持部材２０を組立時と逆の操作で、すなわち、逆回転させてロックピン２３が鍵孔状の軸挿入孔１４の細径部１４ａに合致するようにして、そのまま前方に引き戻すと、軸挿入孔１４から取り外すことができる。この荷重支持部材２０の逆回転操作によってロックピン２３とカム面１３との接触力が急速に除かれて拡張固定部材１０の受部片１１と押え部片１２との接合が緩められることにより、支持部材２の案内溝３内側面に対する拡張固定部材１０の接触力が消去することになり、固定が解かれる。   When removing the load support member 20 in the load support device 1 thus provided, after removing the support arm 30, the holding member 25 is pulled forward against the acting force of the coil spring 27 incorporated therein. The protrusion 25d is pulled away from the small-diameter portion 14a of the shaft insertion hole 14 to release the rotation prevention, and then the load supporting member 20 is operated in the reverse operation during assembly, that is, reversely rotated, so that the lock pin 23 is shaped like a keyhole. If the shaft insertion hole 14 is pulled back forward so as to match the small diameter portion 14a of the shaft insertion hole 14, the shaft insertion hole 14 can be removed. By the reverse rotation operation of the load support member 20, the contact force between the lock pin 23 and the cam surface 13 is rapidly removed and the joint between the receiving piece 11 and the holding piece 12 of the expansion fixing member 10 is loosened. The contact force of the expansion fixing member 10 with respect to the inner surface of the guide groove 3 of the support member 2 is erased, and the fixing is released.

次に、荷重支持装置の他の実施形態が図５によって示されている。この実施形態のものは、前記実施形態とその基本構成において同じものであるから、前記実施形態と異なる部分を除いて同一もしくは同様の部分について同一の符号を付して、その説明を省略する。   Next, another embodiment of the load bearing device is illustrated by FIG. The thing of this embodiment is the same as that of the said embodiment in the said embodiment, The same code | symbol is attached | subjected about the same or similar part except a different part from the said embodiment, and the description is abbreviate | omitted.

この実施形態の支持部材２Ａは、取付座４ａ，４ａとなる鍔部が後面側の両側に形成され、案内溝３の開口部を一部内側へ絞縮させた形状にされている。したがって、開口部の両外側に段部５ａ，５ａが形成され、ここにカバー部片１６の両側突縁部１６ａが係合して開口部を覆うようにされている。また、拡張固定部材１０は、前述のものとほぼ同様のものが組み込まれる。   The support member 2A of this embodiment has a shape in which the flanges to be the mounting seats 4a and 4a are formed on both sides on the rear side, and the opening of the guide groove 3 is partially contracted inward. Accordingly, stepped portions 5a and 5a are formed on both outer sides of the opening, and both side protrusions 16a of the cover piece 16 are engaged with each other to cover the opening. Further, the expansion fixing member 10 is incorporated substantially the same as described above.

使用に際しては、前記支持部材２Ａを壁面構成時取付座４ａ，４ａがボードの裏面側に位置するようにして、その取付座４ａ，４ａをボードに対して小ネジなどで固定するので、壁表面を仕上げる際に取付座４ａ，４ａが存在せず、体裁よく仕上げることができる。なお、機能的には前記実施形態のものと同様である。   When using the support member 2A, the mounting seats 4a, 4a are positioned on the back side of the board when the wall surface is configured, and the mounting seats 4a, 4a are fixed to the board with a small screw or the like. The mounting seats 4a and 4a are not present when finishing, so that it can be finished with good appearance. The function is the same as that of the above embodiment.

以上の説明においては、支持部材を縦方向に配置して使用するものについて記載したが、その支持部材を棚あるいは吊りかけ支持具の配置に相応した高さ位置で横向きに配置して使用することも可能である。このような方式の場合は、拡張固定部材の向きが前述とは９０°変位した状態で支持部材の案内溝内に収まることになる。このような使用形式にあっては、拡張固定部材に固定力を加えない場合でも、落ちることがないので、案内溝に沿って任意の位置に移動させて固定することができる。したがって、荷重支持位置が変更される頻度が高い場合は、好都合である。また、この形式によれば、無負荷時に落下する恐れがないので、支持部材の案内溝底面に軸受け孔を設けることなく使用できる。   In the above description, the support member is described as being used in the vertical direction. However, the support member should be used in a horizontal position at a height corresponding to the position of the shelf or hanging support. Is also possible. In the case of such a system, the direction of the expansion fixing member is accommodated in the guide groove of the support member in a state in which the direction of the expansion fixing member is displaced by 90 °. In such a usage form, even if a fixing force is not applied to the expansion fixing member, it does not fall, so that it can be fixed by being moved to an arbitrary position along the guide groove. Therefore, it is advantageous when the load support position is frequently changed. Moreover, according to this form, since there is no possibility of falling at the time of no load, it can be used without providing a bearing hole on the bottom surface of the guide groove of the support member.

なお、前述の支持部材２を縦型配置する場合、図示省略するが、その長さ方向に複数箇所で拡張固定部材１０を前記の要領で使用して、荷重支持部材を取付けるようにして被支持体を取り付け支持することが任意に行える。   When the above-described support member 2 is vertically disposed, although not shown in the figure, the extended fixing members 10 are used in the above-described manner at a plurality of locations in the length direction to support the load support member. The body can be attached and supported arbitrarily.

また、図示省略するが、前述の支持部材をそのまま横向きにして壁体に取り付け、その横向きの支持部材内案内溝に、拡張固定部材を挿入して、前記要領で荷重支持部材を前記拡張固定部材に装着するようにすれば、前記同様に複数の荷重支持部材と拡張固定部材とを所要の間隔で配置することにより棚支持を行える。この方式によるならば、支持部材内に組込まれた拡張固定部材が横方向にスライドさせることが容易であるので、所望位置に移動させて簡単に棚構成ができるのである。   Although not shown, the support member is mounted on the wall body in the horizontal direction as it is, and the extension fixing member is inserted into the guide groove in the horizontal support member, and the load support member is connected to the expansion fixing member in the manner described above. If it mounts | wears with, a shelf support can be performed by arrange | positioning a several load support member and an expansion fixing member at a required space | interval similarly to the above. According to this method, the expansion and fixing member incorporated in the support member can be easily slid in the horizontal direction, so that it can be easily moved to a desired position to form a shelf structure.

さらに、図６に示されるのは、荷重支持装置の他の実施形態を表わす平面視図である。この実施形態の荷重支持装置は、基本的の前述の実施形態のものと同様であるが、支持部材の一部を異にするものである。したがって、前述の実施形態のものと同一の部分については同一の符号を付して詳細な説明を省略する。   FIG. 6 is a plan view showing another embodiment of the load supporting device. The load support device of this embodiment is the same as that of the basic embodiment described above, but a part of the support member is different. Therefore, the same parts as those of the above-described embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

この実施形態では、支持部材２Ｂが取付座部を有しないものであり、その他の構成である拡張固定部材１０や荷重支持部材２０については前述のものと同様である。したがって、この実施形態の荷重支持装置では、支持部材を壁体の内部に埋め込んで保持するような方式を採用する。機能については前述のものとほぼ同様に機能する。   In this embodiment, the support member 2B does not have a mounting seat portion, and the expansion fixing member 10 and the load support member 20 which are other configurations are the same as those described above. Therefore, the load support device of this embodiment employs a method in which the support member is embedded and held inside the wall body. The functions are almost the same as those described above.

また、この実施形態の荷重支持装置にあっては、支持部材２Ｂを床面などに敷設して、荷重支持部材２０を直立状態にして、支持アーム３０を直立した支柱として下端を荷重支持部材２０に支持させることにより、その支柱（支持アーム）に図示省略するが別途支持アームを周囲に向けて取付けるようにすれば直立した展示物品の支持体として使用することができる。   Further, in the load support device of this embodiment, the support member 2B is laid on the floor or the like, the load support member 20 is set upright, and the support arm 30 is set up as an upright column with the lower end at the load support member 20. Although not shown in the figure, the support arm can be used as a support for an upright display article if it is separately attached to the support (support arm).
