Description

本発明は可搬式作業台に関するものである。   The present invention relates to a portable work table.

建築工事において使用される可搬式作業台１３の作業床１４には、図６に示すように、長辺方向の両端部に踏み外しを防ぐための感知用突起１５を設けている。この感知用突起１５は、プラスチック製のキャップであり、これを作業床１４の既存孔１６に差し込んで設置している。また、その他の可搬式作業台としては、例えば特開２００４−６８４３６号の発明が知られている。
特開２００４−６８４３６号公報 As shown in FIG. 6, the work floor 14 of the portable work table 13 used in the construction work is provided with sensing protrusions 15 for preventing stepping off at both ends in the long side direction. The detection projection 15 is a plastic cap, which is installed by being inserted into the existing hole 16 of the work floor 14. As another portable work table, for example, the invention of Japanese Patent Application Laid-Open No. 2004-68436 is known.
JP 2004-68436 A

しかし、上記の可搬式作業台における感知用突起はプラスチック製であるため、キャップの部分が折れやすく、メンテナンス費用が余分に掛かってしまうという問題があった。また感知用突起が小さく、しかもその設置間隔が大きいため作業者の足裏で感知し難いという問題もあった。   However, since the sensing protrusions in the portable workbench are made of plastic, the cap portion is easily broken, and there is a problem that extra maintenance costs are required. There is also a problem that it is difficult to detect with the soles of the workers because the detection protrusions are small and the installation interval is large.

本発明は、上記のような問題に鑑みてなされたものであり、その目的は、作業者の足裏の感覚、視覚および聴覚で作業床の端部が感知できる可搬式作業台を提供することである。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a portable work table in which the end of the work floor can be sensed by the sense, visual and auditory sense of the soles of the workers. It is.

以上の課題を解決するための可搬式作業台は、作業床の長辺方向の両端部に踏み外し防止用の感知板を短辺方向に沿ってボルトで設置し、該感知板が短辺幅とほぼ同じ幅でかつ中央部が高くなった山形状の鋼板であり、その上面に突起が設けられてなることを特徴とする。また感知板が有彩色で着色されていることを含むものである。
また可搬式作業台は、作業床の長辺側の両端部に踏み外し防止用の感知板を短辺方向に沿って設け、該感知板が空気入りのチューブであり、該チューブが複数の空気室に仕切られて形成され、該仕切部に、二つの空気室をつなぐ空気笛が設けられてなることを特徴とする。また感知板が有彩色で着色されていることを含むものである。 In order to solve the above problems, a portable work table is constructed by installing a sensing plate for preventing stepping off at both ends in the long side direction of the work floor with bolts along the short side direction, and the sensing plate has a short side width. It is a mountain-shaped steel plate having substantially the same width and a raised central portion , and a protrusion is provided on the upper surface thereof. It also includes that the sensing plate is colored with a chromatic color.
Further, the portable work table is provided with a sensing plate for preventing stepping off at both ends on the long side of the work floor along the short side direction, the sensing plate is a pneumatic tube, and the tube is a plurality of air chambers. It is formed by partitioning, and the partition portion is provided with an air whistle that connects two air chambers. It also includes that the sensing plate is colored with a chromatic color.

作業床の長辺方向の両端部に短辺幅とほぼ同じ幅で、かつ山形形状の感知板を設けたことにより、作業者の足裏で作業床の端部を感知することができる。また感知板が有彩色で着色されたことにより、作業者の視覚により作業床の端部を感知することができる。空気入りのチューブからなる感知板の一方の空気室を作業者が踏むと、この空気室からの他の空気室への空気の流れで空気笛が鳴らされるので、作業者の聴覚により作業床の端部を感知することができる。   By providing a chevron-shaped sensing plate having the same width as the short side at both ends in the long side direction of the work floor, it is possible to sense the end of the work floor with the soles of the workers. Further, since the sensing plate is colored with a chromatic color, the end of the work floor can be sensed by the operator's vision. When an operator steps on one of the air chambers of a sensing plate made of a pneumatic tube, an air whistle is generated by the flow of air from this air chamber to the other air chamber. The edge can be sensed.

以下、本発明の可搬式作業台（以下、作業台という）の実施の形態を図面に基づいて説明する。本実施の形態において、同じ構成は同じ符号を付して説明し、異なった構成にのみ異なった符号を付して説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a portable work table (hereinafter referred to as a work table) according to the present invention will be described with reference to the drawings. In the present embodiment, the same components are described with the same reference numerals, and only different components are described with different reference numerals.

図１および図２は、第１の実施の形態の作業台１を示したものである。この作業台１は、４本の脚２で支持された、長さ1130〜1500mmの作業床３の長辺方向の両端部に踏み外し防止用の感知板４がボルト５で固定されて構成されている。この感知板４は短辺幅とほぼ同じ幅でかつ中央部が高くなった山形状の鋼板であり、その上面に突起６が設けられている。また感知板４は作業者の視覚で感知しやすいように赤、青、黄色などの有彩色で着色されている。また感知板４は作業者がつまずかず、かつ感知できる高さに形成されている。このように感知板４は作業床３にボルト５でしっかりと固定されているため、使用後の洗浄時において容易に外れたり、破損したりすることがない。 1 and 2 show a work table 1 according to the first embodiment. This work table 1 is constituted by a detection plate 4 for preventing a stepping off being fixed with bolts 5 at both ends in a long side direction of a work floor 3 having a length of 1130 to 1500 mm supported by four legs 2. Yes. The sensing plate 4 is a mountain-shaped steel plate having a width substantially equal to the short side width and having a high central portion , and a projection 6 is provided on the upper surface thereof. The sensing plate 4 is colored with chromatic colors such as red, blue, and yellow so that it can be easily sensed by the operator's vision. The sensing plate 4 is formed at a height that can be sensed by an operator without tripping. As described above, since the sensing plate 4 is firmly fixed to the work floor 3 with the bolts 5, the sensing plate 4 is not easily detached or damaged during cleaning after use.

図３〜図５は、第２の実施の形態の作業台７を示したものである。この作業台７はゴムチューブまたはビニールチューブの感知板８が両面テープやマジックテープ（登録商標）などの接着部材９で作業床３に接着されたものであり、これ以外は上記の作業台１と同じ構成である。この感知板８はゴムチューブまたはビニールチューブが二つの空気室１０に仕切られ、この仕切部１１に空気笛１２が二つの空気室１０にわたって設けられたものである。したがって、この空気室１０は空気笛１２で繋がっているため、図５に示すように、作業者が一方の空気室１０に乗ると、その空気で空気笛１２を鳴らすため、作業者が聴覚により作業床３の端部を感知できるようになっている。   3 to 5 show a workbench 7 according to the second embodiment. The work table 7 is a rubber tube or vinyl tube sensing plate 8 bonded to the work floor 3 with an adhesive member 9 such as double-sided tape or Velcro (registered trademark). It is the same configuration. In this sensing plate 8, a rubber tube or a vinyl tube is partitioned into two air chambers 10, and an air whistle 12 is provided in the partition portion 11 over the two air chambers 10. Accordingly, since the air chamber 10 is connected by the air whistle 12, as shown in FIG. 5, when the operator gets on one air chamber 10, the air whistle 12 is sounded by the air. The end of the work floor 3 can be sensed.
