Description

本発明は、建築工事現場、建築物の天井や壁面などの内外装作業、電気配線作業などに使用する可搬式作業台に関するものである。   The present invention relates to a portable work table used for construction work sites, interior / exterior work such as ceilings and wall surfaces of buildings, electrical wiring work, and the like.

かかる可搬式作業台１は、従来、例えば図１８に示すように、一対の支柱脚４ａ間に複数の踏み桟５を適宜間隔で取り付けて梯子状の主脚４を形成し、該梯子状の主脚４の一対間に長方形状の天板３を回動自在に取り付け、さらに、天板３と主脚４との間に途中で屈曲自在なステイ７を介装している。   Conventionally, as shown in FIG. 18, for example, the portable work table 1 has a ladder-shaped main leg 4 formed by attaching a plurality of step bars 5 at appropriate intervals between a pair of support legs 4a. A rectangular top plate 3 is rotatably mounted between a pair of main legs 4, and a stay 7 is interposed between the top plate 3 and the main legs 4.

また、天板３の四隅に棒状の手掛かり部材６を立設して、主脚４を昇降する際の手掛かりとしている。この手掛かり部材６は可搬式作業台の認定基準で備え付けが規定されているもので、天板３面高さが１．５ｍを超える可搬式作業台には必ず付設されるものである。   Further, bar-like clue members 6 are erected at the four corners of the top plate 3 to serve as clues when the main leg 4 is raised and lowered. The clue member 6 is provided for provision according to the certification standards for portable worktables, and is always attached to a portable worktable whose top plate 3 surface height exceeds 1.5 m.

しかしながら、前記手掛かり部材６は主脚４を昇降する際の安全を確保するためのものであり、天板３上を歩行し、また、この上で作業する際に、天板３からの転落防止を図ることはできない。   However, the clue member 6 is intended to ensure safety when the main leg 4 is raised and lowered, and prevents falling from the top plate 3 when walking on the top plate 3 and working on it. Can not be planned.

そこで、図１９に示すように天板３からの転落防止手段としてはコ字型の枠状の手摺り２１を別途用意し、これを天板３の長手方向にそって手掛かり部材６の間に別途立設している。   Therefore, as shown in FIG. 19, a U-shaped frame-shaped handrail 21 is separately prepared as means for preventing the fall from the top plate 3, and this is arranged between the clue members 6 along the longitudinal direction of the top plate 3. Separately set up.

そして、使用時には主脚４を昇り、手掛かり部材６を掴んで、天板３の上に上りこの上に立って、または歩行しながら作業する。この場合、作業に気を取られるなどして天板３上で滑ったりしても、手摺り２１により天板３から転落、墜落することが防止される。   In use, the main leg 4 is lifted, the clue member 6 is gripped, and the work is performed while standing on the top plate 3 or walking. In this case, even if the work is distracted and slips on the top plate 3, the handrail 21 prevents the fall or fall from the top plate 3.

前記先行技術は当業者間で一般的に行われているものであり、文献公知発明にかかるものではない。   The prior art is generally performed by those skilled in the art, and does not relate to a known literature.

前記のような可搬式作業台は、脚立などに代わる安全な作業台として急速に普及している。しかしながら、前記手摺り２１は認定基準で備え付けが規定されているものではないため、現実には後付けのオプション部品になっていることが多い。このため、作業者にとっては、手摺りの取り付け・取り外しの手間と時間が嵩むことから、手摺りを取り付けないで作業することも多く、転落・墜落事故を起こすことも多い。   The portable work table as described above is rapidly spreading as a safe work table to replace a stepladder or the like. However, since the handrail 21 is not stipulated by the accreditation standard, in reality, it is often a retrofitted optional part. For this reason, since it takes time and effort to attach and remove the handrail for the worker, the work is often performed without attaching the handrail, and a fall / fall accident is often caused.

また、手摺り２１は別部品となるため、部品点数が増え、運搬や保管場所のスペースも必要とするだけでなく、発注などの伝票処理業務も煩雑となり、面倒である。   Further, since the handrail 21 is a separate part, the number of parts is increased, and not only a space for transportation and storage is required, but also a slip processing work such as ordering becomes complicated and troublesome.

本発明の目的は前記従来例の不都合を解消するものとして、手掛かり部材を備えた可搬式作業台においては、この手掛かり部材を利用することで手摺りを後付けではなく、常設のものとし、しかも天板側方への組み立ても容易で簡単に設置でき、天板からの転落・墜落事故発生を防止し安全性を向上できる可搬式作業台を提供することにある。   An object of the present invention is to eliminate the inconvenience of the conventional example, and in a portable work table provided with a clue member, a handrail is made permanent, not retrofitted, by using this clue member. It is an object of the present invention to provide a portable work table that can be easily and easily assembled on the side of a plate, can prevent a fall / fall accident from the top plate, and can improve safety.

本発明は前記目的を達成するため、請求項１記載の発明は、一対の梯子状の主脚間に天板を架け渡し、前記天板の４隅に中空管の手掛かり部材を立設した可搬式作業台において、前記手掛かり部材内に、その上部から手摺り上桟を上方に引き出し自在に収納するとともに、手掛かり部材の上部と手摺り上桟の端部とを回動自在に連結し、この連結部は、手掛かり部材の上部に装着され手摺り上桟引出し用の長孔を形成したキャップと、手摺り上桟の端部に形成され前記引出し用の長孔よりも径の大きい係止突出部とで構成することを要旨とするものである。   In order to achieve the above object, according to the present invention, a top plate is bridged between a pair of ladder-shaped main legs, and a clue member for a hollow tube is erected at four corners of the top plate. In the portable work table, the handrail upper rail is housed in the handhold member so as to be freely drawn upward from the upper portion thereof, and the upper portion of the handhold member and the end portion of the handrail upper rail are rotatably connected. This connecting part is a cap that is mounted on the upper part of the clasp member and has a long hole for pulling out the handrail upper rail, and a lock that is formed at the end of the handrail upper rail and has a larger diameter than the long hole for the drawer. The gist of the invention is that it is constituted by a protruding portion.

請求項１記載の発明によれば、手摺り上桟が手掛かり部材に取り付けてあるから、手掛かり部材に対して手摺り上桟を引き出して回動するだけで手摺り上桟を天板の長手方向の上方にそって配置でき、天板側部上方の開口を手摺り上桟で遮断でき、よって、天板からの転落や墜落を防止できる。   According to the first aspect of the present invention, since the handrail upper bar is attached to the clue member, the handrail upper bar is moved in the longitudinal direction of the top plate only by pulling the handrail upper bar with respect to the handcuff member and turning it. The opening above the side of the top plate can be blocked by the handrail upper rail, and therefore, the fall or fall from the top plate can be prevented.

そして、手摺り上桟は後付けで取り付けるものではなく、前記のように予め手掛かり部材に取り付けてあるから、手摺り上桟を別途用意する必要もなく、取り付けや取り外しの手間も省け、保管スペースや運搬も不要で、ワンタッチ的にしかも必ず取り付けることができる。   And the handrail upper rail is not attached retrofit, but it is attached to the clue member in advance as described above, so there is no need to prepare the handrail upper rail separately, it is possible to save the installation and removal, storage space and There is no need for transportation, and it can be attached with one touch.

また、手摺り上桟の不使用時には、手摺り上桟は手掛かり部材の内部に収納できるので邪魔にならないから、複数の天板を連結して大きなステージとして使用するような場合に便利である。   Further, when the upper rail of the handrail is not used, the upper rail of the handrail can be housed inside the clue member and does not get in the way, so it is convenient when a plurality of top plates are connected and used as a large stage.

さらに、既存の可搬式作業台であっても、手掛り部材が中空であれば、手掛かり部材内に手摺り上桟をスライド自在に収納して、手掛り部材の上にキャップを取り付ければ、手摺り上桟を簡単に取り付けられる。   Furthermore, even in the case of an existing portable work table, if the handhold member is hollow, the handrail upper bar can be slidably stored in the handhold member, and a cap can be mounted on the handhold member to raise the handrail. Easy to attach the crosspiece.

請求項２記載の発明は、前記キャップは、断面円弧状で、円弧面にそって長孔を形成し、手摺り上桟に形成した係止突出部は前記円弧面に合致する曲面を有することを要旨とするものである。   According to a second aspect of the present invention, the cap has an arc shape in cross section, a long hole is formed along the arc surface, and the locking protrusion formed on the handrail upper rail has a curved surface that matches the arc surface. Is a summary.

請求項２記載の発明によれば、手摺り上桟には係止突出部が形成してあるから、これがキャップの長孔の縁に係止する。よって、手摺り上桟が長孔から抜け出ることはない。そして、手摺り上桟を手掛かり部材から垂直方向に最大長引出した状態で、これを回動すれば、係止突出部の曲面がキャップの円弧面にそって滑るから、水平方向にスムーズに方向を変換でき、手摺り上桟を所定位置に容易に配設できる。   According to the second aspect of the invention, since the locking projection is formed on the handrail upper rail, this locks to the edge of the long hole of the cap. Therefore, the handrail upper rail does not come out of the long hole. When the upper rail of the handrail is pulled out from the clue member in the maximum length in the vertical direction, if this is rotated, the curved surface of the locking projection slides along the arc surface of the cap, so the direction is smooth in the horizontal direction. The handrail upper rail can be easily disposed at a predetermined position.

以上述べたように本発明の可搬式作業台は、手摺り上桟を手掛かり部材に垂直方向にスライド自在で、かつ水平方向に回動自在に取り付けたから、手掛かり部材から手摺り上桟を引上げ、さらに天板の長手方向にそって水平に回動するだけで、手摺り上桟を天板の側方上部に配設でき、手摺り部材を別途用意することなく、また、格別の工具も必要とせずに、天板に手摺り上桟を簡単に設けることができる。   As described above, the portable workbench of the present invention is such that the handrail upper rail is attached to the handhold member so as to be slidable in the vertical direction and pivotable in the horizontal direction, so that the handrail upper rail is pulled up from the handhold member, Furthermore, by simply rotating horizontally along the longitudinal direction of the top plate, the upper rail of the handrail can be placed on the upper side of the top plate, and there is no need for a separate handrail member, and a special tool is required. Without the handrail, a handrail upper rail can be easily provided on the top board.

そして、手摺り上桟を水平に９０度回動した状態ではキャップに形成してある長孔の縁に手摺り上桟の側部が載置するようにして係止されるから、この状態で手摺り上桟は水平に係止される。   When the upper rail of the handrail is rotated 90 degrees horizontally, the side portion of the upper rail of the handrail is locked so as to be placed on the edge of the long hole formed in the cap. The handrail upper rail is locked horizontally.

そして、手摺り上桟のために格別に保管スペースや運搬スペースも必要とせず、保管や運搬の際には手掛かり部材の内部に収納でき、別部材として突出することなくコンパクトにできる。   Further, no special storage space or transport space is required for the balustrade upper rail, and it can be stored inside the clue member during storage and transport, and can be made compact without protruding as a separate member.

以下、図面について本発明の実施形態を詳細に説明する。図１は、本発明の可搬式作業台の実施形態を示す正面図、図２は同上側面図で、本発明の可搬式作業台の基本構造は、図１８、図１９に示した従来例と基本的には同様であるから、同一の参照符号を付してここでの詳細な説明は省略する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of the portable worktable of the present invention, FIG. 2 is a side view of the same, and the basic structure of the portable worktable of the present invention is the same as the conventional example shown in FIGS. Since they are basically the same, the same reference numerals are assigned and detailed description thereof is omitted here.

本発明の可搬式作業台も、基本構造は従来と同様、一対の支柱脚４ａ間に複数の踏み桟５を適宜間隔で取り付けて梯子状の主脚４を形成し、該梯子状の主脚４の一対間に長方形状の天板３を回動自在に取り付け、さらに、天板３と主脚４との間に途中で屈曲自在なステイ７を介装している。   The basic structure of the portable work table of the present invention is the same as in the prior art, and a plurality of step bars 5 are attached at appropriate intervals between a pair of support legs 4a to form a ladder-shaped main leg 4, and the ladder-shaped main leg. A rectangular top plate 3 is rotatably mounted between a pair of four, and a stay 7 that is bendable midway is interposed between the top plate 3 and the main leg 4.

また、天板３の四隅、すなわち主脚４と天板３との昇降口に位置させて円管、角管などによる中空管の手掛かり部材６を主脚４から取付金具で回動自在に立設した。これら、主脚４、天板３は材質としてはアルミニウムを使用する。   In addition, a clue member 6 of a hollow tube such as a circular tube or a square tube is positioned at the four corners of the top plate 3, that is, at the elevation opening between the main leg 4 and the top plate 3, and can be rotated from the main leg 4 with a mounting bracket. Established. The main legs 4 and the top plate 3 are made of aluminum as a material.

本発明はかかる構成の可搬式作業台１において、図１に示すように両側のそれぞれの手掛かり部材６内に、その上部から手摺り上桟８を上方に引き出し自在に収納するとともに、手掛かり部材６の上部と手摺り上桟８の端部とを垂直方向に回動自在に連結する。   According to the present invention, in the portable work table 1 having such a configuration, as shown in FIG. And an end of the handrail upper rail 8 are connected so as to be rotatable in the vertical direction.

この連結部の構造は、手掛かり部材６の上部に装着されるキャップ２と、手摺り上桟８の下端部に形成した係止突出部８ａとで構成され、前記キャップ２には手摺り上桟８の引出し用の長孔２ａを形成し、前記係止突出部８ａは前記引出し用の長孔２ａよりも径を大きく形成して抜け出し防止部材を兼用する。   The structure of this connecting portion is composed of a cap 2 mounted on the upper portion of the clue member 6 and a locking projection 8a formed on the lower end portion of the handrail upper rail 8. The cap 2 has an upper rail for the handrail. 8 is formed with a diameter larger than that of the drawer long hole 2a and also serves as a pull-out preventing member.

また、前記キャップ２は、少なくとも内面側の上面を球面または円筒形状の円弧状とした断面蒲鉾状に形成し、長孔２ａは円弧面にそって、かつ、下端縁が手掛かり部材６と直角の水平に位置するように形成されて、手摺り上桟８に形成した係止突出部８ａは前記円弧面に合致する曲面を有するものとして例えば図４に示す円筒状、図３、図５に示す略球状などに形成する。   Further, the cap 2 is formed in a cross-sectional shape having at least an upper surface on the inner surface side having a spherical or cylindrical arc shape, the long hole 2a is along the arc surface, and the lower end edge is perpendicular to the clue member 6 The locking projection 8a formed on the handrail upper bar 8 is formed in a horizontal position and has a curved surface matching the arc surface, for example, a cylindrical shape shown in FIG. 4, and shown in FIGS. It is formed into a substantially spherical shape.

手掛かり部材６および手摺り上桟８の材質は、軽量で適度な強度を有するものとしてアルミニウムまたはアルミニウム合金がよいが、鉄、樹脂などを使用することも可能である。   The material of the clue member 6 and the handrail upper bar 8 is preferably aluminum or an aluminum alloy as being lightweight and having an appropriate strength, but iron, resin, or the like can also be used.

図６〜１０は、両側の手掛り部材６からそれぞれ引き出した手摺り上桟８ｃ同士の連結部の構造を示し、一方の手摺り上桟８の上部にコイルバネ１０を巻回し、このコイルバネ１０の巻回部分の手摺り上桟８に連結パイプ１１を被覆する。   6 to 10 show the structure of the connecting portion between the handrail upper bars 8c drawn from the handhold members 6 on both sides. A coil spring 10 is wound around the upper part of one handrail upper bar 8, and the coil spring 10 is wound. The connecting pipe 11 is covered with the handrail upper rail 8 of the turning portion.

この連結パイプ１１に連結用の溝条１２を正面矢印状に形成する。図中１３はコイルバネ１０の外れ防止用のストッパーとなるプレートで連結パイプ１１の底部開口を閉塞する。   A groove 12 for connection is formed in the connection pipe 11 in a front arrow shape. In the figure, reference numeral 13 denotes a plate serving as a stopper for preventing the coil spring 10 from coming off, and closes the bottom opening of the connecting pipe 11.

他方の手摺り上桟８の先端には図１０に示すように前記溝条１２に挿入するピン１４を突設しておく。   As shown in FIG. 10, a pin 14 to be inserted into the groove 12 is projected from the tip of the other handrail upper bar 8.

次に使用法を図１１〜図１６について説明する。図１１は手摺り上桟８が手掛かり部材６内に収納された状態で、主脚４と一体になるようにこれに並行に折り畳まれている。この状態から図１２に示すように手掛り部材６を天板３の上方にひきおこせば、図１３に示すように手摺り上桟８が手掛り部材６内に収納されている状態で天板３の端部に立設される。   Next, the usage will be described with reference to FIGS. FIG. 11 shows a state in which the handrail upper bar 8 is housed in the clue member 6 and is folded in parallel with the main leg 4 so as to be integrated therewith. If the handle member 6 is raised above the top plate 3 as shown in FIG. 12 from this state, the top plate 3 of the top plate 3 is stored in the state where the handrail upper rail 8 is housed in the handle member 6 as shown in FIG. Stands at the end.

この状態から手摺り上桟８を天板３の側部上方に配設するには、図１４に示すように手摺り上桟８の上部をつかんで長孔２ａから引き出してそのまま垂直方向の上方に引上げれば、下端の係止突出部８ａがキャップ２の内面上部に当接し、それ以上の引上げが阻止される。   In order to dispose the handrail upper bar 8 above the side of the top plate 3 from this state, as shown in FIG. When pulled up, the locking projection 8a at the lower end comes into contact with the upper part of the inner surface of the cap 2, and further pulling is prevented.

この状態で、図１５に示すように手摺り上桟８を天板３の側部にそってその長手方向に倒せば、手摺り上桟８は手掛かり部材６から抜け出ることなく、連結状態で係止突出部８ａがキャップ２の内側で回動し、手摺り上桟８は長孔２ａにそってが水平位置まで垂直方向に回動する。   In this state, as shown in FIG. 15, if the handrail upper bar 8 is tilted in the longitudinal direction along the side of the top plate 3, the handrail upper bar 8 does not come out of the clue member 6 and is engaged in the connected state. The stop protrusion 8a rotates inside the cap 2, and the handrail upper rail 8 rotates vertically along the long hole 2a to the horizontal position.

そして、図１６に示すように長孔２ａの下端縁に手摺り上桟８が当接しそれ以上の回動が阻止された状態で水平位置に手摺り上桟８が保持され、手摺り上桟８が天板３の側部上方に配設される。   Then, as shown in FIG. 16, the handrail upper rail 8 is held in a horizontal position in a state where the handrail upper rail 8 is in contact with the lower end edge of the long hole 2a and further rotation is prevented, and the handrail upper rail 8 is held. 8 is disposed above the side of the top 3.

他方の側の手摺り上桟８も同様にして引き出し、天板３の側部上方に水平に配設する。そして、図１０に示すように両方の手摺り上桟８の端部をつき合わせ、コイルバネ１０の弾力に抗して他方の手摺り上桟８に突設してあるピン１４を一方の手摺り上桟８の先端に設けた連結パイプ１１に形成してある溝条１２に挿入し、その後ピン１４の位置を溝条１２の端部に移動させれば、コイルバネ１０の弾力によりピン１４はこの位置に係止される（図１７の状態）。   Similarly, the handrail upper rail 8 on the other side is pulled out and disposed horizontally above the side of the top plate 3. Then, as shown in FIG. 10, the ends of both handrail upper rails 8 are brought together, and the pin 14 protruding from the other handrail upper rail 8 against the elasticity of the coil spring 10 is attached to one handrail. When the pin 14 is inserted into the groove 12 formed on the connecting pipe 11 provided at the tip of the upper bar 8 and then the position of the pin 14 is moved to the end of the groove 12, the pin 14 is moved by the elasticity of the coil spring 10. The position is locked (the state shown in FIG. 17).

これにより図１に示すように両方の側の手摺り上桟８，８が連結される。   Thereby, as shown in FIG. 1, the handrail upper bars 8 and 8 of both sides are connected.

不使用時には前記とは逆の動作で手摺り上桟８を手掛かり部材６内に収納すれば、可搬式作業台１を扁平に折り畳む際に突出することがない。   When the handrail upper bar 8 is housed in the clasp member 6 by the reverse operation to the above when not in use, the portable workbench 1 does not protrude when folded flat.

また、手掛かり部材６には、角管を使用するから強度も十分確保できる。   In addition, since the clue member 6 uses a square tube, sufficient strength can be secured.

なお、全ての実施形態において手掛かり部材６や手摺り上桟８が折り畳まれた状態は、複数の可搬式作業台１を連結して大きなステージとして使用する場合などに、天板３から上方に突出する部材をなくす場合にも対応できる。   In all the embodiments, the state in which the clue member 6 and the handrail upper rail 8 are folded protrudes upward from the top plate 3 when a plurality of portable worktables 1 are connected and used as a large stage. It is possible to cope with the case where the member to be removed is eliminated.
