Description

この発明は、主材と延長材とを長手方向に突き合わせた状態で着脱自在に接続する接続構造に関する。 The present invention relates to a connection structure in which a main member and an extension member are removably connected in a state where they abut against each other in the longitudinal direction.

大型で重量のある医療機器や電子機器、冷蔵庫、サーバー、精密機器、光学機器等を設置する場合には、その設置場所周辺におけるスペースの有効活用や通路の確保等の観点から、このような機器類を建物の壁面に近接させて配置したり、入隅コーナ部分に納まるように配置したりするのが一般的である。 When installing large and heavy medical equipment, electronic equipment, refrigerators, servers, precision equipment, optical equipment, etc., such equipment should be It is common to place such items close to the wall of a building, or in a corner.

ところで、上記のような機器類では、その構造や機能、操作性、デザイン性等を考慮して、メンテナンスや修理を行うための点検口や修理口を機器本体の側面や後面に設けていることが多いが、特に点検口や修理口を機器本体の後面に設けた機器類は、建物の壁面や入隅コーナ部分に沿わせて配置した場合、メンテナンスや修理の際に、その作業を行えるだけの空間を機器類の後面と建物の壁面との間に確保するために、建物の壁面から離れる方向に移動させる必要がある。 By the way, in the above-mentioned devices, inspection ports and repair ports for maintenance and repairs are provided on the side or rear of the device body, taking into consideration its structure, function, operability, design, etc. However, especially for equipment that has an inspection or repair port on the rear of the device itself, if it is placed along the wall or inside corner of a building, it may be difficult to carry out maintenance or repair work. In order to secure space between the rear of the equipment and the wall of the building, it is necessary to move it away from the wall of the building.

そして、床面に直接設置されている機器類の移動作業は、機器類を持ち上げて移動させることになるので、その機器類が大型で重量のあるものである場合には、安全性の確保に留意する必要があるし、多くの人手を確保したり重機や工具等を用意したりするために、メンテナンスや修理の本来の作業とは別の手間や費用がかかるという問題がある。 Moving equipment installed directly on the floor requires lifting and moving the equipment, so if the equipment is large and heavy, it may be difficult to ensure safety. It is necessary to take this into account, and there is a problem in that it requires a lot of manpower, heavy equipment, tools, etc., which requires additional effort and expense in addition to the original maintenance and repair work.

このような機器類の移動作業における問題点を解決する手段としては、例えば特許文献1に記載されているようなガイドレール装置を用いることが考えられる。すなわち、特許文献1のガイドレール装置は、断面コの字状のレールの内側に長手方向移動可能な可動部材を設けたものであり、そのレールを機器類の移動方向に沿って床面上に配し、可動部材に機器類を支持させるようにすれば、メンテナンスや修理の際にも機器類をレールに沿って安全かつ省力的に移動できるようになり、多くの人手や重機、工具等を用意する必要がなくなる。 As a means for solving such problems in moving equipment, it is conceivable to use a guide rail device as described in Patent Document 1, for example. That is, the guide rail device of Patent Document 1 has a movable member that is movable in the longitudinal direction inside a rail having a U-shaped cross section, and moves the rail onto a floor surface along the moving direction of equipment. If the equipment is supported by movable parts, the equipment can be moved safely and labor-savingly along the rails during maintenance or repair, saving a lot of manpower, heavy equipment, tools, etc. There is no need to prepare anything.

しかし、上記のようなガイドレール装置を設置する場合、通常、そのレールの長さは機器類の移動距離を確保するために機器類の前後方向の寸法よりも長くなっているので、そのレールの先端側部分が機器類の設置位置よりも前方の床面まで突出することになり、機器類の前方で人がレールにつまずいて転倒したり、レールが別の機器類や工具等の運搬の妨げになったりするという問題が生じる。 However, when installing a guide rail device like the one above, the length of the rail is usually longer than the longitudinal dimension of the equipment in order to ensure the distance the equipment can move. The tip end protrudes to the floor in front of the equipment installation position, which may cause people to trip over the rail in front of the equipment and fall, or the rail to interfere with the transportation of other equipment or tools. The problem arises that it becomes

この問題に対しては、ガイドレール装置のレールを、機器類の前後方向の寸法に合わせた長さの主レール(主材)と、主レールの先端に着脱自在に接続される延長レール(延長材)とに分割して、機器類を移動させるときだけ主レールに延長レールを接続し、機器類が通常の設置位置にあるときは主レールから延長レールを取り外しておくようにすることが考えられる。 To solve this problem, the rail of the guide rail device has a main rail (main material) with a length that matches the longitudinal dimensions of the equipment, and an extension rail (extension rail) that is detachably connected to the tip of the main rail. A good idea would be to connect the extension rail to the main rail only when moving the equipment, and remove the extension rail from the main rail when the equipment is in its normal installation position. It will be done.

上記のようにレール同士を着脱自在に接続する接続構造としては、2つのレールの互いの突き合わせ端面の間に複数のピンを配置するもの(例えば、特許文献2参照。)や、一方のレールの突き合わせ端部で幅方向に延びるピンに、他方のレールの突き合わせ端部に設けたフックを引っ掛けた状態で一方のレールを回動させて、両レールの突き合わせ端部を互いに係合させるもの(例えば、特許文献3参照。)が知られている。 Connection structures for removably connecting rails as described above include those in which a plurality of pins are arranged between the abutting end surfaces of two rails (see, for example, Patent Document 2), and those in which one rail is A hook provided at the butt end of the other rail is hooked to a pin extending in the width direction at the butt end, and one rail is rotated to engage the butt ends of both rails with each other (e.g. , see Patent Document 3) are known.

しかしながら、上記特許文献2で提案されているピン結合による接続構造は、大きな引張強度や耐折れ曲がり強度(以下、あわせて「接続強度」ともいう。)を必要とされる用途には採用しにくいという難点がある。 However, the pin connection structure proposed in Patent Document 2 is difficult to adopt for applications that require high tensile strength and bending strength (hereinafter also referred to as "connection strength"). There are some difficulties.

すなわち、例えば上記のピン結合による接続構造を前述のガイドレール装置の主レールと延長レールの接続に採用した場合、機器類を延長レール上へ移動させるときには、延長レールを主レールから引き離す方向の力が作用するので、接続構造の引張強度が低いと、主レールと延長レールの間に隙間が生じ、その隙間に機器類を支持している可動部材の一部が落ち込んで機器類の移動ができなくなるおそれがある。また、主レールと延長レールの突き合わせ端面どうしが密着しなくなると耐折れ曲がり強度も低くなるので、床面の性状によっては、両レール上を移動する機器類の重量が延長レールに加わったときに、延長レールが主レールとの接続部分を支点として先端下がりに傾斜し、機器類をスムーズに主レール上に戻せなくなるおそれもある。このため、重量の大きい機器類を移動させるためのレールの接続構造は、高い接続強度が得られるようにピンの本数を増やす必要があり、それによって接続作業に手間のかかるものとなり、構造的にも複雑なものとなる。 In other words, for example, if the above-mentioned pin connection connection structure is used to connect the main rail and extension rail of the guide rail device described above, when moving equipment onto the extension rail, a force in the direction of separating the extension rail from the main rail is applied. If the tensile strength of the connection structure is low, a gap will be created between the main rail and the extension rail, and a part of the movable member supporting the equipment will fall into the gap, making it impossible for the equipment to move. There is a risk that it will disappear. Also, if the butt ends of the main rail and extension rail no longer come into close contact with each other, the bending strength will decrease, so depending on the nature of the floor surface, when the weight of equipment moving on both rails is added to the extension rail, There is also a risk that the extension rail will tilt downward at the end of the extension rail using the connection part with the main rail as a fulcrum, making it impossible to smoothly return the equipment onto the main rail. For this reason, the rail connection structure for moving heavy equipment needs to increase the number of pins in order to obtain high connection strength, which makes the connection work time-consuming and structurally It also becomes complicated.

一方、上記特許文献3で提案されている接続構造を前述のガイドレール装置に採用した場合には、主レールにその本体とは別部材のピンを、延長レールにその本体とは別部材のフックをそれぞれ設ける必要があり、構造が複雑で、製造コストも高くなるという問題がある。また、主レールと延長レールの互いの突き合わせ端部は、その突き合わせ端面が互いに嵌合するように傾斜して、先端ほど厚みが薄く強度が小さくなるので、床面の性状によっては、機器類の重量が延長レールに加わったときに、主レールの突き合わせ端部が撓んで延長レールが先端下がりに傾斜し、ピン結合による接続構造の場合と同様、機器類をスムーズに主レール上に戻せなくなるおそれがある。 On the other hand, when the connection structure proposed in Patent Document 3 is adopted in the above-mentioned guide rail device, the main rail has a pin that is a separate member from the main body, and the extension rail has a hook that is a separate member from the main body. It is necessary to provide each of them, which poses a problem that the structure is complicated and the manufacturing cost is also high. In addition, the butt ends of the main rail and extension rail are sloped so that the butt ends fit into each other, and the thickness and strength decrease toward the ends, so depending on the nature of the floor surface, equipment may When weight is applied to the extension rail, the butt end of the main rail will bend, causing the extension rail to tilt downward, making it impossible to smoothly return equipment onto the main rail, as in the case of a pin-joint connection structure. There is.

そこで、この発明は、簡単な構成で、長手方向で互いに突き合わされる主材と延長材とを着脱自在に、かつ高い接続強度で接続できる接続構造を提供することを課題とする。 SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a connection structure that has a simple configuration, can connect a main member and an extension member that are butted against each other in the longitudinal direction removably and with high connection strength.

上記の課題を解決するために、この発明の接続構造は、長手方向に延びる底壁および縦壁を有する主材と、前記主材の底壁および縦壁にそれぞれ長手方向で突き合わされる底壁および縦壁を有する延長材とを、前記主材と延長材の互いの突き合わせ端部に設けられ、凹凸嵌合により長手方向に係合する係合機構によって着脱自在に接続する構成とした。 In order to solve the above problems, the connection structure of the present invention includes a main member having a bottom wall and a vertical wall extending in the longitudinal direction, and a bottom wall that abuts against the bottom wall and the vertical wall of the main member in the longitudinal direction. and an extension member having a vertical wall are detachably connected to each other by an engagement mechanism that is provided at the abutting ends of the main member and the extension member and engaged in the longitudinal direction by concave-convex fitting.

すなわち、長手方向で互いに突き合わされる主材と延長材とを着脱自在に接続する接続構造の係合機構として、凹凸嵌合により長手方向に係合するものを採用することにより、主材と延長材との接続状態において、その係合機構の係合部位が主材と延長材とを引き離す方向の力を支持し、それによって互いに密着した状態で保持される主材と延長材の突き合わせ端面が主材と延長材とを折り曲げる方向の力を確実に支持することができ、高い接続強度(引張強度および耐折れ曲がり強度)が得られるようにしたのである。 In other words, by employing an engagement mechanism in the connection structure that removably connects the main member and the extension member that are butted against each other in the longitudinal direction, the main member and the extension member are engaged in the longitudinal direction through concave-convex fitting. In the state of connection with the material, the engagement portion of the engagement mechanism supports the force in the direction of separating the main material and the extension material, thereby causing the abutting end surfaces of the main material and the extension material to be held in close contact with each other. It is possible to reliably support the force in the direction of bending the main member and the extension member, and to obtain high connection strength (tensile strength and bending strength).

また、この係合機構は主材と延長材の互いの突き合わせ端部を凹凸嵌合させるものであるから、前述のピン結合による接続構造やフックを幅方向に延びるピンに引っ掛ける接続構造に比べて簡単な構成となっている。 In addition, since this engagement mechanism engages the butt ends of the main member and the extension member in a concave-convex manner, it is better than the above-mentioned connection structure using a pin connection or the connection structure in which a hook is hooked on a pin extending in the width direction. It has a simple configuration.

ここで、前記係合機構としては、前記主材と延長材のうちの一方の縦壁の突き合わせ端面から斜め上方または斜め下方に突出する係合突起と、他方の縦壁の突き合わせ端面で開口し、前記係合突起が嵌まり込む係合凹部とからなるものを採用することができる。そして、前記係合機構を、前記主材と延長材の互いの突き合わせ端部を近接させた状態で、前記延長材を主材に対して傾斜した姿勢から直線状に延長された姿勢に移行させることにより、前記係合突起が係合凹部に嵌まり込むように形成されているものとすれば、主材が他の設置物等で囲まれた状態でも、主材に対する延長材の接続作業や取り外し作業が、延長材と主材の周囲の設置物等との干渉を生じることなくスムーズに行えるようになる。そのための具体的な構成としては、例えば、前記係合機構の係合突起が、前記主材または延長材の縦壁の突き合わせ端面から上向きに湾曲するように突出しており、前記係合凹部は、前記係合突起が嵌まり込む湾曲形状に形成されているものとすることができる。 Here, the engagement mechanism includes an engagement protrusion that projects obliquely upward or downward from the abutting end surface of one of the vertical walls of the main member and the extension member, and an opening at the abutting end surface of the other vertical wall. , and an engagement recess into which the engagement protrusion fits. Then, the engagement mechanism is caused to shift the extension member from an inclined position relative to the main member to a linearly extended position with the butted ends of the main member and the extension member brought close to each other. Therefore, if the engaging protrusion is formed so as to fit into the engaging recess, it is possible to connect the extension member to the main member even when the main member is surrounded by other installation objects. Removal work can be carried out smoothly without interference between the extension member and objects installed around the main member. As a specific configuration for this purpose, for example, the engagement protrusion of the engagement mechanism protrudes upwardly from the abutting end surface of the vertical wall of the main member or the extension member, and the engagement recess is configured such that: The engagement protrusion may be formed into a curved shape into which it fits.

あるいは、前記係合機構として、前記主材と延長材のうちの一方の縦壁の突き合わせ端の近傍の上端面または下端面で開口する係合凹部と、他方の縦壁の突き合わせ端から一方の縦壁の外側面または内側面に沿って長手方向に延びる腕部と、前記腕部から幅方向に突出して前記係合凹部に嵌まり込む係合突起とからなるものを採用することもできる。 Alternatively, the engagement mechanism may include an engagement recess that opens at the upper end surface or lower end surface near the abutting end of one of the vertical walls of the main member and the extension member, and a recess that opens from the abutting end of the other vertical wall. It is also possible to employ one that consists of an arm extending in the longitudinal direction along the outer or inner surface of the vertical wall, and an engagement protrusion that protrudes from the arm in the width direction and fits into the engagement recess.

ここで、上記のような係合機構の具体的な構成によらず、前記主材および延長材が、それぞれ前記底壁の幅方向両側に前記縦壁が形成された断面コの字状の部材である場合は、前記係合機構は、前記主材および延長材の幅方向両側で互いに突き合わされる縦壁にそれぞれ設けるとよい。 Here, irrespective of the specific configuration of the engagement mechanism as described above, the main member and the extension member each have a U-shaped cross section with the vertical walls formed on both sides of the bottom wall in the width direction. In this case, it is preferable that the engagement mechanism is provided on each vertical wall that abuts against each other on both sides in the width direction of the main member and the extension member.

また、前記主材の底壁と延長材の底壁の互いの突き合わせ端部に、凹凸嵌合により前記延長材を主材に対して上下方向に拘束する補強機構を設ければ、その補強機構でも接続状態の主材と延長材とを折り曲げる方向の力を支持するようになるので、耐折れ曲がり強度を一層向上させることができる。 Further, if a reinforcing mechanism is provided at the butt ends of the bottom wall of the main material and the bottom wall of the extension material to restrain the extension material in the vertical direction with respect to the main material through concave-convex fitting, the reinforcing mechanism However, since it supports the force in the direction of bending the main member and the extension member in the connected state, the bending resistance can be further improved.

また、前記主材の底壁と延長材の底壁の互いの突き合わせ端部に、凹凸嵌合により前記延長材を主材に対して幅方向に拘束する拘束機構を設ければ、接続状態の主材と延長材の幅方向の位置ずれを防止できるようになる。 Furthermore, if a restraining mechanism is provided at the butt ends of the bottom wall of the main member and the bottom wall of the extension member to restrain the extension member in the width direction with respect to the main member through concave-convex fitting, the connection state can be maintained. Misalignment of the main material and the extension material in the width direction can be prevented.

さらに、前記主材と延長材のうちの一方の縦壁の突き合わせ端部に、他方の縦壁の突き合わせ端部に幅方向で摺接して、前記延長材を主材に対して幅方向に位置決めする位置決め片を設ければ、主材と延長材の接続作業における幅方向の位置合わせがしやすくなるうえ、接続状態の幅方向の位置ずれを防止する効果も得られる。 Further, the extension member is positioned in the width direction with respect to the main member by slidingly contacting the butting end of one vertical wall of the main member and the extension member in the width direction with the butting end of the other vertical wall. If a positioning piece is provided, it becomes easier to align the main member and the extension member in the width direction during the connection work, and it is also possible to prevent misalignment in the width direction in the connected state.

この発明の接続構造は、上述したように、主材と延長材の互いの突き合わせ端部に設けられ、凹凸嵌合により長手方向に係合する係合機構を採用したものであるから、主材と延長材とを着脱自在に接続でき、かつその接続状態において高い接続強度を得ることができる。したがって、この接続構造によって接続される主材と延長材は、必要に応じて着脱でき、その接続状態において引張荷重や曲げ荷重のかかる用途でも、接続部分に隙間や折れ曲がりを生じにくく安定して使用することができる。 As described above, the connection structure of the present invention employs an engagement mechanism that is provided at the abutting ends of the main member and the extension member and engaged in the longitudinal direction by fitting the main member and the extension member. and the extension member can be detachably connected, and high connection strength can be obtained in the connected state. Therefore, the main member and extension member connected by this connection structure can be attached and detached as necessary, and even in applications where tensile loads or bending loads are applied in the connected state, the connection part is unlikely to have gaps or bends and can be used stably. can do.

It is laid on the floor surface a in a posture extending in the direction. The rear end portions of the extension rails 3 are connected to the respective tip ends of the main rails 2 in a butted state. The length of the extension rail 3 is such that when the device b is pulled out to the tip of the extension rail 3, there is a gap between the back of the device b, where an inspection port or a repair port is provided, and the wall of the building during maintenance or repair. The workspace is designed to create the necessary work space.

前記主レール2および延長レール3は、図2および図3に示すように、それぞれ帯状の金属板の折り曲げ加工によって形成された断面コの字状の部材であり、長手方向に延びる底壁2a、3aとその幅方向両側に起立する一対の縦壁2b、3bとを有し、互いの端面が突き合わせ可能な同一の断面形状となっている。 As shown in FIGS. 2 and 3, the main rail 2 and the extension rail 3 are members each having a U-shaped cross section formed by bending a band-shaped metal plate, and have a bottom wall 2a extending in the longitudinal direction, 3a and a pair of vertical walls 2b, 3b standing up on both sides in the width direction, and have the same cross-sectional shape so that their end surfaces can butt against each other.

図2に示すように、主レール2の内側には、主レール2とほぼ同じ長さで前記可動部材4を主レール2の長手方向に誘導する第1誘導レール5が設けられている。第1誘導レール5は、帯状の金属板を折り曲げ加工して上面が開放する溝形に形成したもので、長手方向に延びる底板5aと、その幅方向両側に起立する一対の側板5bと、両側板5bの上端から内側へ延びる上板5cとからなり、その底板5aが主レール2の底壁2aの上面に固定されている。また、底板5aの上面の幅方向中央には、後述するように可動部材4の横振れを防ぐための金属帯板製の第1ガイド6が、底板5aの全長にわたって設けられている。なお、この第1ガイドは、図2に示したもの以外の断面形状であってもよく、第1誘導レールの底板の幅方向中央位置を、上方に突出する角形や山形、円弧状のものや、複数となるW形、逆m形等、単、複数含め最適な形状に折り曲げ加工して形成するようにしてもよい。 As shown in FIG. 2, a first guide rail 5 is provided inside the main rail 2 and has approximately the same length as the main rail 2 and guides the movable member 4 in the longitudinal direction of the main rail 2. The first guide rail 5 is formed by bending a band-shaped metal plate into a groove shape with an open top surface, and includes a bottom plate 5a extending in the longitudinal direction, a pair of side plates 5b standing up on both sides in the width direction, and a bottom plate 5a extending in the longitudinal direction. It consists of an upper plate 5c extending inward from the upper end of the plate 5b, and its bottom plate 5a is fixed to the upper surface of the bottom wall 2a of the main rail 2. Further, a first guide 6 made of a metal band plate is provided at the center in the width direction of the upper surface of the bottom plate 5a over the entire length of the bottom plate 5a to prevent the movable member 4 from wobbling laterally. Note that this first guide may have a cross-sectional shape other than that shown in FIG. , a plurality of W-shapes, inverted m-shapes, etc., single or plural, may be bent into an optimal shape.

また、図3に示すように、延長レール3の内側には、延長レール3とほぼ同じ長さで、主レール2から出てきた可動部材4を延長レール3の長手方向に誘導する第2誘導レール7が設けられている。第2誘導レール7は、第1誘導レール5の底板5aと同じ厚みで同程度の幅を有する帯状の金属板であり、その上面の幅方向中央に第1ガイド6と同じ断面寸法の金属帯板製の第2ガイド8が全長にわたって設けられている。なお、この第2ガイドも、図3に示したもの以外の断面形状であってもよく、第2誘導レールの底板の幅方向中央位置を、上方に突出する角形や山形、円弧状のものや、複数となるW形、逆m形等、単、複数含め最適な形状に折り曲げ加工して形成するようにしてもよい。 In addition, as shown in FIG. 3, a second guide is provided inside the extension rail 3, which has approximately the same length as the extension rail 3, and which guides the movable member 4 coming out from the main rail 2 in the longitudinal direction of the extension rail 3. A rail 7 is provided. The second guide rail 7 is a band-shaped metal plate having the same thickness and approximately the same width as the bottom plate 5a of the first guide rail 5, and a metal band having the same cross-sectional size as the first guide 6 at the center of the upper surface in the width direction. A second guide 8 made of a plate is provided over the entire length. Note that this second guide may also have a cross-sectional shape other than that shown in FIG. , a plurality of W-shapes, inverted m-shapes, etc., single or plural, may be bent into an optimal shape.

そして、主レール2と延長レール3とを直線状に接続したときには、第1誘導レール5の底板5aと第2誘導レール7が突き合わされるとともに、第1ガイド6と第2ガイド8が突き合わされるようになっている。 When the main rail 2 and the extension rail 3 are connected linearly, the bottom plate 5a of the first guide rail 5 and the second guide rail 7 are butted against each other, and the first guide 6 and the second guide 8 are butted against each other. It has become so.

前記可動部材4は、図1および図5に示すように、第1誘導レール5と同程度の長さを有する支持台9の長手方向両端部に機器bの設置脚cの下端部が嵌まり込む受け部9aを設け、その支持台9の各受け部9aの前後に左右一対の車輪10を取り付けたもので、各車輪10が第1ガイド6および第2ガイド8の左右両側で第1誘導レール5の底板5a上および第2誘導レール7上を転動することにより、機器bを支持した状態で主レール2および延長レール3の内側を長手方向に移動するようになっている。そして、各対の左右の車輪10の間隔を第1ガイド6および第2ガイド8の幅とほぼ同じ寸法に設定することにより、可動部材4の直線的な前後移動を誘導して横振れを防止している。 As shown in FIGS. 1 and 5, in the movable member 4, the lower ends of the installation legs c of the equipment b fit into both longitudinal ends of the support base 9, which has a length comparable to that of the first guide rail 5. A pair of left and right wheels 10 are attached to the front and rear of each receiving portion 9a of the support base 9, and each wheel 10 is provided with a first guide on both the left and right sides of the first guide 6 and the second guide 8. By rolling on the bottom plate 5a of the rail 5 and on the second guide rail 7, it moves in the longitudinal direction inside the main rail 2 and the extension rail 3 while supporting the device b. By setting the interval between the left and right wheels 10 of each pair to be approximately the same as the width of the first guide 6 and the second guide 8, the movable member 4 is guided to move back and forth in a straight line, thereby preventing lateral vibration. are doing.

次に、このガイドレール装置1の主レール2と延長レール3を接続する接続構造について説明する。この接続構造は、図1と図4乃至図6に示すように、主レール2の縦壁2bと延長レール3の縦壁3bの互いの突き合わせ端部に設けた係合機構11と、主レール2の底壁2aと延長レール3の底壁3aの互いの突き合わせ端部に設けた補強機構12および拘束機構13を含む。 Next, a connection structure for connecting the main rail 2 and the extension rail 3 of this guide rail device 1 will be explained. As shown in FIGS. 1 and 4 to 6, this connection structure consists of an engagement mechanism 11 provided at the abutting ends of the vertical wall 2b of the main rail 2 and the vertical wall 3b of the extension rail 3, and the main rail. The extension rail 3 includes a reinforcing mechanism 12 and a restraining mechanism 13 provided at the abutting ends of the bottom wall 2a of the extension rail 2 and the bottom wall 3a of the extension rail 3.

前記係合機構11は、ガイドレール装置1の左右両側に設けられており、延長レール3の両側の縦壁3bの突き合わせ端面から斜め上方に突出する係合突起14と、主レール2の両側の縦壁2bの突き合わせ端面で開口し、係合突起14が嵌まり込む係合凹部15とからなる。 The engagement mechanism 11 is provided on both left and right sides of the guide rail device 1, and includes an engagement protrusion 14 that projects obliquely upward from the abutting end surfaces of the vertical walls 3b on both sides of the extension rail 3, and an engagement protrusion 14 on both sides of the main rail 2. It consists of an engaging recess 15 that opens at the butting end surfaces of the vertical wall 2b and into which the engaging protrusion 14 fits.

図1乃至図4に示すように、係合突起14は、フック状に形成されており、延長レール3の縦壁3bの突き合わせ端面から後方に突出する根元部14aと、根元部14aの後端から上向きに湾曲する湾曲部14bとからなる。その根元部14aは、上縁がほぼ長手方向に沿って延びているのに対して、下縁が根元から斜め上方へ延びており、後端に向かって上下の幅が狭くなる形状とされている。また、湾曲部14bは、上端縁が半円状に形成されている。 As shown in FIGS. 1 to 4, the engagement protrusion 14 is formed in a hook shape, and includes a root portion 14a that projects rearward from the abutting end surface of the vertical wall 3b of the extension rail 3, and a rear end of the root portion 14a. It consists of a curved portion 14b that curves upward from the bottom. The root portion 14a has a shape in which the upper edge extends substantially along the longitudinal direction, while the lower edge extends obliquely upward from the root, and the vertical width becomes narrower toward the rear end. There is. Moreover, the upper end edge of the curved portion 14b is formed in a semicircular shape.

一方、係合凹部15は、主レール2の縦壁2bの突き合わせ端面で開口する開口部15aと、開口部15aの後端から上向きに湾曲する湾曲凹部15bとからなり、係合突起14に対応する形状に形成されている。すなわち、その開口部15aは、上縁がほぼ長手方向に沿って延びているのに対して、下縁が開口端から斜め上方へ延びており、後端に向かって上下の幅が狭くなる形状とされている。また、湾曲凹部15bは、上端縁が半円状に形成されている。 On the other hand, the engagement recess 15 consists of an opening 15a that opens at the abutting end surfaces of the vertical wall 2b of the main rail 2, and a curved recess 15b that curves upward from the rear end of the opening 15a, and corresponds to the engagement protrusion 14. It is formed in a shape that That is, the opening 15a has a shape in which the upper edge extends substantially along the longitudinal direction, while the lower edge extends obliquely upward from the opening end, and the vertical width becomes narrower toward the rear end. It is said that Further, the upper edge of the curved recess 15b is formed in a semicircular shape.

したがって、図7に示すように、延長レール3を後端下がりに傾斜させた状態で、その後端部を主レール2の先端部に近接させ、延長レール3の係合突起14を主レール2の係合凹部15に挿入しながら、延長レール3を先端が下がる方向に回動させていくと、延長レール3が水平に(主レール2に対して直線状に延長された姿勢に)なったときに、係合突起14の全体が係合凹部15に嵌まり込んで、主レール2と延長レール3とを接続することができる。 Therefore, as shown in FIG. 7, with the rear end of the extension rail 3 tilted downward, the rear end is brought close to the tip of the main rail 2, and the engaging protrusion 14 of the extension rail 3 is connected to the main rail 2. When the extension rail 3 is rotated in the direction in which the tip is lowered while being inserted into the engagement recess 15, the extension rail 3 becomes horizontal (in a posture extended linearly with respect to the main rail 2). In addition, the entire engagement protrusion 14 fits into the engagement recess 15 to connect the main rail 2 and the extension rail 3.

すなわち、この係合機構11では、主レール2が機器bと床面aとに上下で挟まれていても、延長レール3を機器bおよび床面aと干渉することなくスムーズに主レール2に接続することができる。そして、係合突起14全体が係合凹部15に嵌まり込むと同時に、主レール2の縦壁2bと延長レール3の縦壁3bとが突き合わされて面一となって、主レール2と延長レール3の接続状態が保持されるようになる。 That is, with this engagement mechanism 11, even if the main rail 2 is vertically sandwiched between the device b and the floor surface a, the extension rail 3 can be smoothly attached to the main rail 2 without interfering with the device b and the floor surface a. Can be connected. Then, at the same time that the entire engagement protrusion 14 fits into the engagement recess 15, the vertical wall 2b of the main rail 2 and the vertical wall 3b of the extension rail 3 are butted against each other and become flush with each other, so that the main rail 2 and the extension The connected state of the rail 3 is now maintained.

前記補強機構12は、図2乃至図6に示すように、第1誘導レール5の底板5aに、その先端の幅方向中央位置で開口して第1ガイド6の先端部の下方に入り込む略台形状の凹欠部16を設け、第2誘導レール7の後端に第1誘導レール5の凹欠部16に嵌合する嵌合突部17を設けたもので、その嵌合突部17を凹欠部16に嵌合させると、同時に嵌合突部17が第1ガイド6の先端部と主レール2の底壁2aとの間に形成されている上下の隙間に嵌まり込み、延長レール3が主レール2に対して幅方向および上下方向に拘束されるようになっている。 As shown in FIGS. 2 to 6, the reinforcing mechanism 12 is a substantially pedestal that opens in the bottom plate 5a of the first guide rail 5 at the center position in the width direction of its tip and enters below the tip of the first guide 6. A shaped recessed notch 16 is provided, and a fitting protrusion 17 that fits into the concave notch 16 of the first guide rail 5 is provided at the rear end of the second guide rail 7. When it is fitted into the recessed notch 16, the fitting protrusion 17 is simultaneously fitted into the vertical gap formed between the tip of the first guide 6 and the bottom wall 2a of the main rail 2, and the extension rail 3 is restrained from the main rail 2 in the width direction and the vertical direction.

なお、この補強機構12では、第1誘導レール5の底板5aと第2誘導レール7の互いの凹凸嵌合部のうち、可動部材4の車輪10が通過する部分がその車輪10の通過方向に対して水平面内で傾いているので、その車輪10が通過するときに衝撃や抵抗を受けにくいものとなっている。 In addition, in this reinforcing mechanism 12, among the mutually uneven fitting parts of the bottom plate 5a of the first guide rail 5 and the second guide rail 7, the part through which the wheels 10 of the movable member 4 pass is aligned in the direction in which the wheels 10 pass. On the other hand, since the wheel 10 is inclined in the horizontal plane, it is less susceptible to impact or resistance when passing the wheel 10.

前記拘束機構13は、図2、図3および図6に示すように、主レール2の底壁2aに、その先端から前方に突出する略台形状の嵌合突部18を幅方向に2つ並べて設け、延長レール3の底壁3aの後端に主レール2の2つの嵌合突部18のそれぞれに嵌合する凹欠部19を設けたもので、その嵌合突部18を凹欠部19に嵌合させると、延長レール3が主レール2に対して幅方向に拘束されるようになっている。 As shown in FIGS. 2, 3 and 6, the restraint mechanism 13 has two substantially trapezoidal fitting protrusions 18 in the width direction that protrude forward from the tip of the bottom wall 2a of the main rail 2. They are arranged side by side, and the rear end of the bottom wall 3a of the extension rail 3 is provided with a concave notch 19 that fits into each of the two fitting protrusions 18 of the main rail 2. When fitted into the portion 19, the extension rail 3 is restrained in the width direction with respect to the main rail 2.

また、図3および図4に示すように、延長レール3の両縦壁3bには、その後端部の外側面に、後端面から後方に突出して、主レール2の縦壁2bの先端部の外側面に幅方向で摺接し、延長レール3を主レール2に対して幅方向に位置決めする位置決め片20が設けられている。その位置決め片20は、後端部分が幅方向外側へわずかに折り曲げられ、延長レール3を主レール2に接続する際の幅方向位置合わせが容易に行えるようになっている。なお、位置決め片20の後端部分は、全体を幅方向外側へ折り曲げる代わりに、内側面を後端に向かって幅方向外側へ傾斜させた形状としてもよい。また、位置決め片20は両縦壁3bに複数設けてもよい。 In addition, as shown in FIGS. 3 and 4, both vertical walls 3b of the extension rail 3 have a rear end protruding from the outer surface of the rear end, and a tip of the vertical wall 2b of the main rail 2. A positioning piece 20 is provided that slides on the outer surface in the width direction and positions the extension rail 3 in the width direction with respect to the main rail 2. The rear end portion of the positioning piece 20 is slightly bent outward in the width direction, so that alignment in the width direction when connecting the extension rail 3 to the main rail 2 can be easily performed. Note that the rear end portion of the positioning piece 20 may have a shape in which the inner surface is inclined outward in the width direction toward the rear end, instead of bending the entire rear end portion outward in the width direction. Further, a plurality of positioning pieces 20 may be provided on both vertical walls 3b.

次に、このガイドレール装置1の使用方法について説明する。まず、主レール2上に設置される機器bを通常使用するときには、図8に示すように、延長レール3を主レール2に接続しない。ここで、主レール2は通常の設置位置にある機器bの前面よりも前方へ突出しないように敷設されており、機器bはその設置脚cを支持する可動部材4に対するストッパ(図示省略)の作動により前後移動を拘束されている。また、図示は省略するが、機器bは建物の壁面に近接して配置されており、機器bの後面と建物の壁面との間にはメンテナンスや修理等を行うための作業空間がない状態となっている。 Next, how to use this guide rail device 1 will be explained. First, when the device b installed on the main rail 2 is normally used, the extension rail 3 is not connected to the main rail 2, as shown in FIG. Here, the main rail 2 is laid so that it does not protrude forward beyond the front surface of the device b in the normal installation position, and the device b has a stopper (not shown) for the movable member 4 that supports the installation leg c. Due to the operation, forward and backward movement is restricted. Although not shown, equipment b is placed close to the wall of the building, and there is no work space for maintenance or repair between the rear of equipment b and the wall of the building. It has become.

そして、機器bのメンテナンスや修理を行うときのみ、延長レール3を主レール2に接続して床面a上に一時的に敷設する。その接続方法は、図7に基づいて説明したように、後端下がりに傾斜させた延長レール3の後端部の係合突起14を主レール2の先端部の係合凹部15に挿入しながら、延長レール3を主レール2に対して直線状に延長された姿勢になるまで回動させて、係合突起14の全体を係合凹部15に嵌め込めばよい。 Then, only when performing maintenance or repair of device b, the extension rail 3 is connected to the main rail 2 and temporarily laid on the floor surface a. The connection method is as explained based on FIG. , the extension rail 3 may be rotated until it assumes a linearly extended position relative to the main rail 2, and the entire engagement protrusion 14 may be fitted into the engagement recess 15.

このとき、延長レール3の両縦壁3bに設けた位置決め片20が、それぞれ主レール2の縦壁2bの先端部の外側面に摺接するので、延長レール3の主レール2に対する幅方向位置合わせは容易に行える。 At this time, the positioning pieces 20 provided on both vertical walls 3b of the extension rail 3 come into sliding contact with the outer surfaces of the tips of the vertical walls 2b of the main rail 2, so that the width direction positioning of the extension rail 3 with respect to the main rail 2 is adjusted. can be easily done.

また、このようにして係合突起14を係合凹部15に嵌め込むと、同時に、第2誘導レール7の嵌合突部17が第1誘導レール5の凹欠部16および第1ガイド6と主レール2の底壁2aとの隙間に嵌まり込むとともに、延長レール3の2つの凹欠部19のそれぞれに主レール2の嵌合突部18が嵌まり込んで、延長レール3が主レール2に接続される(図1、図4乃至図6の状態)。 Furthermore, when the engagement protrusion 14 is fitted into the engagement recess 15 in this manner, the engagement protrusion 17 of the second guide rail 7 is simultaneously fitted into the recess cutout 16 of the first guide rail 5 and the first guide 6. It fits into the gap between the main rail 2 and the bottom wall 2a, and the fitting protrusions 18 of the main rail 2 fit into each of the two recessed notches 19 of the extension rail 3, so that the extension rail 3 becomes the main rail. 2 (states shown in FIGS. 1 and 4 to 6).

延長レール3を主レール2に接続できれば、可動部材4のストッパを解除して、図9に示すように機器bを延長レール3上へ引き出した後、メンテナンスや修理の際、機器bが後ろに戻らないよう再びストッパを作動させて前後移動を拘束し、機器bの後面と建物の壁面との間に作業空間を確保する。そして、その作業空間でのメンテナンスや修理の作業が完了すれば、再びストッパを解除して機器bを主レール2上へ戻した後、ストッパを作動させて前後移動を拘束してから、図7に基づいて説明した接続手順と逆の手順で延長レール3を主レール2から取り外しておけばよい。 If the extension rail 3 can be connected to the main rail 2, after releasing the stopper of the movable member 4 and pulling out the device b onto the extension rail 3 as shown in Fig. 9, the device b can be moved backwards during maintenance or repair. The stopper is operated again to restrict the back and forth movement so that it does not return, and a work space is secured between the rear surface of device b and the wall of the building. When the maintenance and repair work in that work space is completed, the stopper is released again and device b is returned to the main rail 2, and the stopper is activated to restrict its forward and backward movement. What is necessary is to remove the extension rail 3 from the main rail 2 in the reverse order of the connection procedure explained based on .

上述したように主レール2と延長レール3とを着脱自在に接続されるものとし、その主レール2は通常の設置位置にある機器bの前面よりも前方へ突出しないように敷設することにより、機器bの通常使用時には、機器bの前方のスペースでガイドレール装置1が障害物とならず、そのスペースを有効かつ安全な作業空間とすることができる。 As mentioned above, the main rail 2 and the extension rail 3 are connected removably, and the main rail 2 is installed so that it does not protrude beyond the front of the device b in its normal installation position. When the device b is normally used, the guide rail device 1 does not become an obstacle in the space in front of the device b, and the space can be used as an effective and safe work space.

なお、延長レール3の両縦壁3bには、上端縁の所定の長手方向位置に切欠き21が設けられており(図3および図9参照)、延長レール3を主レール2に対して接続したり取り外したりする作業(着脱作業)の途中で、延長レール3が機器bの前面下側のコーナ部と干渉しないようになっている。したがって、この実施形態のように設置位置の機器bの前面が主レール2の先端よりも前方にある場合や、機器bの下面と床面aとの間隔が狭い場合でも、主レール2に対する延長レール3の傾斜角度が大きくとれ、延長レール3の着脱作業が楽な姿勢で、あるいは狭いスペースで行えるという利点がある。なお、この切欠きは、機器の形状や状況に合わせて干渉しないように、適宜形状や数を自由に選択することができる。 Note that both vertical walls 3b of the extension rail 3 are provided with notches 21 at predetermined longitudinal positions on the upper edge (see FIGS. 3 and 9), which allow the extension rail 3 to be connected to the main rail 2. The extension rail 3 is designed not to interfere with the lower front corner of the device b during the work of attaching or removing it (attachment/detaching work). Therefore, even if the front surface of the device b at the installation position is in front of the tip of the main rail 2 as in this embodiment, or even if the distance between the bottom surface of the device b and the floor surface a is narrow, the extension to the main rail 2 There is an advantage that the inclination angle of the rail 3 can be large, and the work of attaching and detaching the extension rail 3 can be done in a comfortable posture or in a narrow space. Note that the shape and number of these notches can be freely selected according to the shape and situation of the device so as not to interfere with each other.

そして、このガイドレール装置1の主レール2と延長レール3との接続構造は、延長レール3の縦壁3bの突き合わせ端面から斜め上方に突出する係合突起14を、主レール2の縦壁2bの突き合わせ端面で開口する係合凹部15に嵌め込んで長手方向に係合させる係合機構11を採用したので、簡単な構成で主レール2と延長レール3とを着脱自在に接続できるだけでなく、その接続状態において、係合機構11の係合部位が主レール2と延長レール3とを引き離す方向の力を支持し、それによって互いに密着した状態で保持される主レール2と延長レール3の互いの突き合わせ端面が主レール2と延長レール3とを折り曲げる方向の力を確実に支持することができ、高い接続強度(引張強度および耐折れ曲がり強度)が得られる。 The connection structure between the main rail 2 and the extension rail 3 of this guide rail device 1 is such that the engagement protrusion 14 that projects obliquely upward from the abutting end surface of the vertical wall 3b of the extension rail 3 is connected to the vertical wall 2b of the main rail 2. Since the engagement mechanism 11 is fitted into the engagement recess 15 that opens at the butting end faces of the rails and engages in the longitudinal direction, it is possible to not only connect the main rail 2 and the extension rail 3 detachably with a simple configuration, but also In the connected state, the engagement portion of the engagement mechanism 11 supports the force in the direction of separating the main rail 2 and the extension rail 3, thereby holding the main rail 2 and the extension rail 3 in close contact with each other. The abutted end faces of the main rail 2 and the extension rail 3 can reliably support the force in the direction of bending, and high connection strength (tensile strength and bending strength) can be obtained.

ここで、主レール2の底壁2aと延長レール3の底壁3aの互いの突き合わせ端部に設けた補強機構12および拘束機構13の構成要素はそれぞれ凹凸嵌合しており、その分、主レール2と延長レール3の折り曲げ方向の力を支持する突き合わせ端面の合計面積が大きくなっていることも、耐折れ曲がり強度の向上に寄与している。また、補強機構12が延長レール3を主レール2に対して上下方向に拘束する作用によっても、耐折れ曲がり強度の向上が図られている。 Here, the components of the reinforcing mechanism 12 and the restraining mechanism 13, which are provided at the butt ends of the bottom wall 2a of the main rail 2 and the bottom wall 3a of the extension rail 3, are fitted in a concave and convex manner, respectively, and the main The increased total area of the abutting end surfaces of the rail 2 and the extension rail 3 that support the force in the bending direction also contributes to improving the bending resistance. Further, the bending resistance is also improved by the action of the reinforcing mechanism 12 restraining the extension rail 3 in the vertical direction with respect to the main rail 2.

したがって、このガイドレール装置1では、床面aの性状によらず、主レール2と接続された延長レール3は、機器bを引き出すときに延長レール3を主レール2から引き離す方向の力が作用しても、主レール2と延長レール3との間に隙間が生じることがなく、延長レール3上に引き出された機器bの重量が加わっても、主レール2との接続部分を支点として先端下がりに傾斜することもない。 Therefore, in this guide rail device 1, regardless of the properties of the floor surface a, the extension rail 3 connected to the main rail 2 is subjected to a force in the direction of separating the extension rail 3 from the main rail 2 when pulling out the device b. Even if the weight of device b pulled out onto the extension rail 3 is added, there will be no gap between the main rail 2 and the extension rail 3. It doesn't slope downward either.

また、主レール2と延長レール3の接続状態において、補強機構12および拘束機構13が延長レール3を主レール2に対して幅方向に拘束する作用と、延長レール3の両縦壁3bに設けた位置決め片20が主レール2の縦壁2bの外側面に摺接する作用によって、延長レール3の主レール2に対する幅方向の位置ずれも防止することができる。 In addition, when the main rail 2 and the extension rail 3 are connected, the reinforcing mechanism 12 and the restraint mechanism 13 act to restrain the extension rail 3 in the width direction with respect to the main rail 2, and the By the action of the positioning piece 20 slidingly contacting the outer surface of the vertical wall 2b of the main rail 2, it is possible to prevent the extension rail 3 from shifting in the width direction with respect to the main rail 2.

そして、これらの特長により、大型で重い機器bのメンテナンスや修理を行うために、主レール2と延長レール3を接続して機器bを延長レール3上に引き出したり、延長レール3上に引き出した機器bを主レール2上に戻したりするときに、その機器bを小さい力でスムーズに前後移動させることができる。 With these features, in order to perform maintenance or repair on large and heavy device b, the main rail 2 and extension rail 3 can be connected and device b can be pulled out onto the extension rail 3 or pulled out onto the extension rail 3. When returning device b onto the main rail 2, device b can be smoothly moved back and forth with a small force.

図10は、この実施形態の接続構造における係合機構11の変形例を示す。この変形例では、係合機構11の係合突起14が、延長レール3の縦壁3bの突き合わせ端面から長手方向に沿って延びる根元部14aと、根元部14aの後端側から上方へ延びたうえで前方へ折れ曲がる屈曲部14cとからなる。そして、この係合突起14と、主レール2の縦壁2の突き合わせ端面で開口し、係合突起14の全体が嵌まり込む形状に形成された係合凹部15とが、凹凸嵌合により長手方向に係合するようになっている。 FIG. 10 shows a modification of the engagement mechanism 11 in the connection structure of this embodiment. In this modification, the engagement protrusion 14 of the engagement mechanism 11 has a root portion 14a extending in the longitudinal direction from the abutting end surfaces of the vertical wall 3b of the extension rail 3, and a root portion 14a extending upward from the rear end side of the root portion 14a. It consists of a bent part 14c that is bent forward at the top. This engagement protrusion 14 and an engagement recess 15 that opens at the abutting end surfaces of the vertical wall 2 of the main rail 2 and are formed in a shape into which the entire engagement protrusion 14 fits are formed in the longitudinal direction by convex-concave fitting. It is adapted to engage in the direction.

なお、上述した第1実施形態の接続構造の係合機構は、主材および延長材の設置場所によっては、係合突起が斜め下方に突出する形態、すなわち係合突起および係合凹部の上下方向の向きを図1乃至図9に示した例と逆にした形態とすることもできる。その場合は、延長材を主材に対して先端下がりに傾斜させた状態で、その後端部を主材の先端部に近接させ、係合突起を係合凹部に挿入しながら、延長材を先端が上がる方向に回動させていくことにより、係合突起の全体を係合凹部に嵌め込んで、主材と延長材とを接続することができる。 Note that the engagement mechanism of the connection structure of the first embodiment described above may have a form in which the engagement protrusion protrudes diagonally downward depending on the installation location of the main member and the extension member, that is, in the vertical direction of the engagement protrusion and the engagement recess. It is also possible to have a configuration in which the direction of the ? is reversed from the example shown in Figs. In that case, with the extension member tilted downward relative to the main member, bring the rear end close to the tip of the main member, and while inserting the engagement protrusion into the engagement recess, insert the extension member at the tip. By rotating in the upward direction, the entire engagement protrusion can be fitted into the engagement recess, thereby connecting the main member and the extension member.

図11乃至図13は、この発明の第2実施形態に係る接続構造を用いたガイドレール装置31の主レール32と延長レール33の接続部分を示す。その主レール32および延長レール33は、それぞれ第1実施形態のものと同じく、帯状の金属板の折り曲げ加工によって形成された断面コの字状の部材であり、長手方向に延びる底壁32a、33aとその幅方向両側に起立する一対の縦壁32b、33bとを有し、互いの端面が突き合わせ可能な同一の断面形状となっている。そして、図示は省略するが、機器を支持した可動部材が主レール32および延長レール33の内側を長手方向に移動するようになっている。 FIGS. 11 to 13 show a connecting portion between a main rail 32 and an extension rail 33 of a guide rail device 31 using a connecting structure according to a second embodiment of the present invention. The main rail 32 and the extension rail 33 are members each having a U-shaped cross section formed by bending a band-shaped metal plate, respectively, as in the first embodiment, and have bottom walls 32a, 33a extending in the longitudinal direction. and a pair of vertical walls 32b, 33b standing up on both sides in the width direction, and have the same cross-sectional shape so that their end surfaces can be butted against each other. Although not shown in the drawings, a movable member supporting the equipment moves in the longitudinal direction inside the main rail 32 and the extension rail 33.

この第2実施形態の接続構造の係合機構41は、ガイドレール装置31の左右両側に設けられており、主レール32の縦壁32bの突き合わせ端の近傍の上端面で開口する矩形の係合凹部42と、延長レール33の縦壁33bの突き合わせ端から主レール32の縦壁32bの外側面に沿って長手方向に延びる腕部43と、その腕部43の後端側の上部から幅方向内側に突出して係合凹部42に嵌まり込む矩形板状の係合突起44とからなる。 The engagement mechanism 41 of the connection structure of the second embodiment is provided on both the left and right sides of the guide rail device 31, and has a rectangular engagement mechanism that opens at the upper end surface near the abutting end of the vertical wall 32b of the main rail 32. An arm portion 43 extends in the longitudinal direction along the outer surface of the vertical wall 32b of the main rail 32 from the butt end of the recess 42 and the vertical wall 33b of the extension rail 33, and an arm portion 43 extends in the width direction from the upper part of the rear end side of the arm portion 43. It consists of a rectangular plate-shaped engagement protrusion 44 that projects inward and fits into the engagement recess 42 .
