  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.

  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.

  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.

  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.

  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 as a handrail, and it is possible to improve safety by preventing the fall of the article by the baseboard, etc. 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.

Is possible. Also, the vertical rail can be shortened by the height of the baseboard, and the strength can be increased.

  The invention according to claim 2 is a handrail erected along the edge of the top plate of the work table, wherein the handrail is provided with a column erected at both ends in the length direction of the table, and between the columns. The gist of the present invention is that it is constituted by an upper rail and a baseboard that are installed horizontally, and a vertical rail that is detachably disposed by a mounting bracket at an appropriate interval between the upper rail and the baseboard.

  According to the second aspect of the present invention, the vertical rail is provided on the handrail and the horizontal rail is not provided as in the prior art. Therefore, there is no horizontal rail for hanging the leg, and the vertical rail can be hung on the leg. Because it is not, it will be difficult to go up to the upper rail, thus preventing accidents such as crashes and falls. Furthermore, since the vertical beam is detachable, it can be easily attached to an existing handrail composed only of a U-shaped frame, and the interval between attachments can be set freely.

  As described above, the handrail of the work table of the present invention can be provided with a baseboard at the same time as the handrail, and the safety can be further improved by preventing an article from dropping by the baseboard.

  In addition, since the handrail has a vertical rail, it is impossible to put a leg on it, and it is possible to prevent the leg from being lifted by a leg without increasing the weight of the handrail. Can prevent accidents from falling and falling, further improve safety, and prevent handrails from being damaged.
