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作業台の手摺りに関するものである。 The present invention relates to a handrail for a work table used for a construction site, interior / exterior work such as a ceiling or wall surface of a building, and electrical wiring work.

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作業台として、可搬式作業台がある。かかる可搬式作業台１は、従来、例えば図１４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。 A portable work table is used as a work table used for construction work sites, interior / exterior work such as ceilings and walls of buildings, and electrical wiring work. Conventionally, as shown in FIG. 14, 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の面の高さが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 stipulated for installation 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、下記特許文献１にも提案されているように、さらに天板３からの転落防止手段としては横桟２２を有する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。図中２３は上桟を示す。 Therefore, as proposed in Patent Document 1 below, a U-shaped frame-shaped handrail 21 having a horizontal rail 22 is additionally prepared as means for preventing the fall from the top plate 3, and this is used as a top plate. 3 is separately provided between the clue members 6 along the longitudinal direction 3. In the figure, 23 indicates an upper rail.

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。
特開２００１−１５２６５９号公報 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.
JP 2001-152659 A

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。そして、安全対策上、横桟２２に脚を掛けて作業することは禁止されているが、実際には、高さが不足する場合には横桟２２に脚を掛けて作業したり、横桟を利用して上桟２３に上がって作業する場合がある。 The portable work table as described above is rapidly spreading as a safe work table to replace a stepladder or the like. For safety reasons, it is forbidden to work with the legs on the horizontal rail 22, but in reality, if the height is insufficient, you can work with the legs on the horizontal rail 22, There is a case where the user goes up to the upper rail 23 and works.

そのため、横桟２２が変形、破損したり、外れたりすることがあり、補修の必要が生じたり、あるいは、作業中に作業台が転倒し、墜落・転倒などの事故が発生することもある。 For this reason, the horizontal rail 22 may be deformed, damaged, or detached, so that it may be necessary to repair it, or the work table may fall during the work, causing an accident such as a fall or a fall.

前者の不都合に対しては、横桟２２の強度をアップして作業員の体重に耐えられるものにすればよいが、このようにすると手摺りの重量が大きくなり、コストアップとなるだけでなく、可搬式の作業台であることを勘案すれば使い勝手のよくないものになってしまう。 For the former inconvenience, it is sufficient to increase the strength of the cross rail 22 so that it can withstand the weight of the worker. However, this does not only increase the weight of the handrail, but also increases the cost. Considering that it is a portable work table, it becomes unusable.

また、前記のような可搬式作業台では、作業床である天板３上のものが落下するのを防止する幅木の取り付けについては何ら考慮されていなかった。なお、幅木を前記手摺りに対して、または、天板に直接取り付けるのでは、部材点数が増加するとともに、取付・撤去の面倒さが増す。 Further, in the portable work table as described above, no consideration has been given to the attachment of the baseboard that prevents the work table 3 as the work floor from falling. Note that, when the skirting board is attached to the handrail or directly to the top plate, the number of members increases and the troublesomeness of attachment / removal increases.

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、手摺りとともに幅木も同時に設けることができ、幅木による物品の落下等の防止により、より安全性を高めることができるとともに、手摺りに脚を掛けることができなくなり、手摺りの重量を大きくすることなしに、墜落や転倒の事故発生を防ぐことができ、安全性をさらに向上でき、また、手摺りの破損も防止できる作業台の手摺りを提供することにある。 The purpose of the present invention is to eliminate the inconvenience of the conventional example, and a baseboard can be provided at the same time with a handrail, and it is possible to improve safety by preventing the fall of the article by the baseboard. Work that can prevent you from putting your feet on the rails, prevents accidents such as falls and falls without increasing the weight of the railings, further improves safety, and prevents damage to the railings It is to provide a handrail for the table.

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手摺りの実施形態を示す斜視図で、可搬式作業台に取り付ける場合である。図２は同上要部の手摺りの第１例を示す正面図、図３は同上側面図で、可搬式作業台の基本構造は、図１４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 perspective view showing an embodiment of the handrail of the portable workbench according to the present invention, which is a case where the handrail is attached to the portable workbench. 2 is a front view showing a first example of the handrail of the main part of the above, FIG. 3 is a side view of the same, and the basic structure of the portable work table is basically the same as the conventional example shown in FIG. Therefore, the same reference numerals are assigned and detailed description thereof is omitted here.

可搬式作業台１は、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。 In the portable work table 1, 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. A rectangular ceiling is formed between the pair of ladder-shaped main legs 4. A plate 3 is rotatably attached, and a stay 7 that can be bent 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.

本発明の手摺り１１はかかる構成の可搬式作業台１において、天板３の長さ方向にそってその縁に立設するが、この手摺り１１は、図１に示すように天板３の長さ方向の両端に立設される支柱１２と、この支柱１２間に水平に架設される上桟１３および幅木１４と、上桟１３と幅木１４との間に適宜間隔で配設される縦桟１５とで構成する。 The handrail 11 of the present invention is erected on the edge of the portable workbench 1 having such a configuration along the length direction of the top plate 3. The handrail 11 is provided on the top plate 3 as shown in FIG. Are arranged at appropriate intervals between the support poles 12 erected at both ends in the longitudinal direction, the upper rail 13 and the baseboard 14 horizontally installed between the support pillars 12, and the upper rail 13 and the baseboard 14. It is comprised with the vertical beam 15 made.

幅木１４は１０ｃｍを超える高さの角型の中空材で形成され、縦桟１５も角型の中空材で形成され、縦桟１５の上桟１３と幅木１４への取り付けは、図４、図５に示すようにプレート状の取付金具１７を用いてボルトまたはリベットなどで固定される。 The skirting board 14 is formed of a rectangular hollow material having a height exceeding 10 cm, the vertical beam 15 is also formed of a rectangular hollow material, and the vertical beam 15 is attached to the upper rail 13 and the skirting board 14 as shown in FIG. As shown in FIG. 5, it is fixed with a bolt or rivet using a plate-like mounting bracket 17.

図示の例では２本の縦桟１５の上下端がそれぞれ上桟１３の下面と幅木１４との上面とに固定されるが、縦桟１５の取り付け数はこれに限定されるものではなく任意に決定できる。また、取付金具１７を使用して上桟１３と幅木１４に取り付けるから、縦桟１５のない既存の手摺りにも簡単に取り付けられる。 In the illustrated example, the upper and lower ends of the two vertical beams 15 are fixed to the lower surface of the upper beam 13 and the upper surface of the skirting board 14, respectively, but the number of vertical beams 15 is not limited to this and is arbitrary. Can be determined. Moreover, since it attaches to the top rail 13 and the baseboard 14 using the attachment bracket 17, it can also be easily attached to the existing handrail without the vertical rail 15.

図中１６は支柱１２の下部に取り付けた取付金具で、この取付金具１６を介して支柱１２が天板３の下縁に取り付けられ、手摺り１１が天板３に固定される。 In the figure, reference numeral 16 denotes a mounting bracket attached to the lower portion of the support 12. The support 12 is attached to the lower edge of the top plate 3 through the mounting bracket 16, and the handrail 11 is fixed to the top 3.

取付金具１６は垂直部１６ａと先端の立ち上がり部１６とを備えるもので、図示は省略した天板３の長辺側の側壁とこの側壁の内側に位置する長辺側中間壁とにそれぞれが当接してボルトやリベットなどで天板３に固定され、固定状態では船底構造となる。 The mounting bracket 16 is provided with a vertical portion 16a and a rising portion 16 at the front end, and the long side wall of the top plate 3 and the long side intermediate wall located inside the side wall are not shown. In contact, it is fixed to the top plate 3 with bolts, rivets, etc., and in the fixed state it has a ship bottom structure.

手摺り１１の天板３の長辺側への着脱可能の固定は、前記特許文献１でも記載されているように、手摺り１１の支柱１２の下部に固定用部材を設けることにより行われる。例えば、固定用部材の垂直部を支柱１２の下部にボルト・ナットなど適宜の手段で固定し、固定用部材の垂直部から延びる立ち上がり部を天板の下面部に当接させ、Ｌ字形金具などからなる板状部材を手摺り１１の支柱１２と天板３にボルト・ナットなどの手段で固着することにより行われる。 The detachable fixing of the handrail 11 to the long side of the top plate 3 is performed by providing a fixing member at the lower portion of the column 12 of the handrail 11 as described in Patent Document 1. For example, the vertical portion of the fixing member is fixed to the lower portion of the support column 12 with an appropriate means such as a bolt and a nut, and the rising portion extending from the vertical portion of the fixing member is brought into contact with the lower surface portion of the top plate, so This is done by fixing a plate-like member made of the above to the support column 12 of the handrail 11 and the top plate 3 by means of bolts and nuts.

手摺り１１の天板３の長辺側への他の固定方式としては、天板３の長辺側に、長辺側側壁と長辺側側壁から内方に位置する長辺側中間壁を設ける。特許文献１の図３〜５に示すように、手摺り１１の支柱１２の下部に、天板３の長辺側側壁に当接する垂直部と、垂直部から延び天板３の長辺側中間壁が形成する溝部に嵌入する立ち上がり部を具えた固定用部材を、例えばボルト・ナットやリベットで取り付けることにより設けるとともに、天板３の上面に当接するＬ字形金具などの板状部材を例えばボルト・ナットやリベットで取り付けることにより設け、特許文献１の図３に示すように、板状部材と固定用部材とにより天板３の長辺側端部を挟持し、板状部材と天板３に穿設した孔を合わせ、この孔にピンを挿通することにより天板３の長辺側に手摺り１１を取り付ける。 As another method for fixing the handrail 11 to the long side of the top plate 3, a long side wall and a long side intermediate wall located inward from the long side wall are provided on the long side of the top plate 3. Provide. As shown in FIGS. 3 to 5 of Patent Document 1, a vertical portion that contacts the long side wall of the top plate 3 and a middle portion on the long side of the top plate 3 that extends from the vertical portion are provided below the support column 12 of the handrail 11. A fixing member having a rising portion that fits into a groove formed by a wall is provided by, for example, bolts, nuts, or rivets, and a plate-like member such as an L-shaped bracket that comes into contact with the upper surface of the top plate 3 is, for example, a bolt As shown in FIG. 3 of Patent Document 1, the long side end of the top plate 3 is sandwiched between the plate-like member and the fixing member, and the plate-like member and the top plate 3 are provided. The handrail 11 is attached to the long side of the top plate 3 by aligning the hole drilled in the hole and inserting a pin into the hole.

以上のようにして天板３の長さ方向に手摺り１１が立設され、この手摺り１１には縦桟１５が取り付けてあるから、天板３での作業中にこの縦桟１５には脚を掛けることができず、また、脚掛りがないから上桟１３にも上がることはできず、安全である。 As described above, the handrail 11 is erected in the length direction of the top plate 3, and the vertical rail 15 is attached to the handrail 11. A leg cannot be hung, and since there is no leg hanger, it cannot go up to the upper rail 13, and it is safe.

さらに、幅木１４の上には上がることはできるが、手摺り１１は取付金具１６により船底構造になって天板３に固定されているから、揺れは少なく、強度も確保できる。 Further, although it can be raised above the skirting board 14, the handrail 11 has a ship bottom structure and is fixed to the top plate 3 by the mounting bracket 16, so that the shaking is small and the strength can be secured.

図６〜図１０は手摺りの第２例を示し、第１例では縦桟１５を角パイプで形成したが、第２例では丸パイプで形成した。そして、縦桟１５の幅木１４への固定手段としてＬ型の取付金具１７を用いた。その他の構成および作用は第１例と同様である。 6 to 10 show a second example of the handrail. In the first example, the vertical rail 15 is formed by a square pipe, but in the second example, it is formed by a round pipe. Then, an L-shaped mounting bracket 17 was used as a means for fixing the vertical rail 15 to the skirting board 14. Other configurations and operations are the same as those in the first example.
